Proprietary Products

In addition to providing cash and spot markets, derivative markets, and data and access solutions, we also offer for trading proprietary products and are a leader in the volatility space with our proprietary products. These proprietary products are built both through our in-house research and development staff of the Data and Access Solutions business and our strategic relationships and license agreements with index providers, which are both described below in further detail. Our most frequently traded proprietary products include SPX options and VIX options and futures.

SPX Options

The S&P 500 Index is an index comprised of 500 large-cap U.S. listed companies. It is one of the most commonly followed indices and is considered a bellwether for the U.S. economy. The SPX options we offer on the S&P 500 Index are exclusive to Cboe and contribute substantially to our volumes and transaction fees. Because of the S&P 500 Index’s status as a bellwether, SPX options are used in many different trading strategies by customers with different goals, including pension funds hedging their equity exposure by buying put options, asset managers seeking enhanced returns by selling covered call options and hedge funds using risk-managed strategies to capture so-called “risk premia” embedded in option prices. We also offer SPX Weeklys options, which have settlements on Mondays, Wednesdays, Fridays and on the last trading day of each month and nearly 24x5 trading in SPX options. We believe these additional expirations provide customers with more precision when hedging overall portfolio risk.

Volatility Trading

Cboe pioneered the trading of exchange-traded volatility products with its introduction of VIX futures in 2004 and VIX options in 2006. The VIX Index (as defined below), although not directly tradable, is based on the mid-point of real-time quotes of SPX options and is designed to reflect investors’ consensus view of future 30-day expected stock market volatility. The VIX methodology provides the basis for the creation of VIX options and futures. The final settlement value of VIX derivatives is determined on their expiration date through a Special Opening Quotation (“SOQ”) of the VIX Index. The SOQ calculation uses opening trade prices of selected options; unless there is no opening price, in which case the opening price used in the SOQ calculation is the midpoint of the highest bid and lowest offer at the time of the opening. Since we started offering these products, we have seen trading from a number of different customer segments utilizing a number of different trading strategies, including hedging extreme stock market declines, also known as “tail risk” hedging, and risk-managed strategies that seek to capture the relative price changes of expected volatility at different times in the future. We also offer VIX Weeklys options and futures, mini VIX futures, and nearly 24x5 trading in VIX options and futures to provide investors with additional tools to trade volatility.

Proprietary Indices

We also calculate and disseminate proprietary indices that are licensed for use by third parties or are used as the basis for other proprietary products. These proprietary indices are built both through our in-house research and development staff of the Data and Access Solutions business and our strategic relationships and license agreements with index providers, which are both described below in further detail. Our proprietary indices include:

In addition to any transaction fee revenue generated on products created based on these indices, we have granted licenses for third parties to use and sublicense some of these proprietary indices to create third-party indices and products. Accordingly, we generate revenue from proprietary indices by distributing them for reference purposes, using them as the basis for proprietary products and licensing them for use for third-party indices and products.

Strategic Relationships

The Company has long-term business relationships with several providers of market indices. We license their indices, including on an exclusive basis, as the foundation for indices, index options and other products. The Company also acquires interests in and agrees to work jointly with key providers to develop new products and services that are expected to capitalize on our core competencies and diversify our sources of revenue. Of particular note are the following:

Data and Access Solutions

The Data and Access Solutions business provides an offering of market data and information solutions products across multiple asset classes and geographic regions that are designed to suit our customers’ diverse needs. The Data and Access Solutions business consists of five product groups:

Front-End Platforms.In addition to the requirements related to operating our U.S. markets imposed by the SEC Cboe provides multiple trading solutions and the CFTC, we also have certain responsibilities for regulating the TPHsservices including Cboe Silexx, LiveVol Pro, FT Options and members that trade on our exchanges. While we have entered into agreements under which FINRA, with respect to our options and equities exchanges, and NFA, with respect to our futures exchange, provide certain regulatory services, we retain ultimate responsibility for the regulation of our TPHs and members. We have begun to perform internally more of the regulatory services that FINRA used to handle. Our ability to comply with applicable laws and rules is largely dependent on the establishment and maintenance of appropriate systems and procedures, our ability to attract and retain qualified personnel, the ability of FINRA and NFA to perform under the RSAs, the ability of FINRA to transition to us any other potential responsibilities under its revised RSA, our ability to complete the new additional responsibilities for regulating our TPHs and members and our oversight of the work done by FINRA and NFA. The SEC and CFTC have broad powers to audit, investigate and enforce compliance and to punish noncompliance by, as applicable, SROs, DCMs and SEFs pursuant to applicable laws, rules and regulations. If a regulatory authority were to find one of our programs of enforcement or compliance to be deficient, our SROs, DCM, or SEF could be the subject of investigations and enforcement proceedings that may result in substantial sanctions, including revocation of registration as a national securities exchange, DCM, or SEF. Any such investigations or proceedings, whether successful or unsuccessful, could result in substantial costs, the diversion of resources, including management time, and potential harm to our reputation, which could have a material adverse effect on our business, financial condition and operating results. In addition, our SROs, DCM, or SEF may be required to modify or restructure their regulatory functions in response to any changes in the regulatory environment, or they may be required to rely on third parties to perform regulatory and oversight functions, each of which may require us to incur substantial expenses and may harm our reputation if our regulatory services are deemed inadequate. In addition, SROs are required by federal law to perform a variety of regulatory functions. In light of these responsibilities, some courts have held that SROs are immune to certain private causes of action relating to the performance of these regulatory functions. There is a risk that some courts may not apply this immunity doctrine to all claims. There is also a risk that legislative or regulatory developments may change the application of this immunity doctrine. Limitations on the application of the immunity doctrine could result in an increased exposure to litigation, and increase liability and/or other legal expenses. Further under the Commodity Exchange Act, CFE and Cboe SEF may be subject to litigation alleging that they have acted in bad faith. We also could be exposed to liability to regulators or other governmental authorities even in situations where immunity would bar a civil claim. Our business may be adversely affected by price competition. The securities industry is characterized by intense price competition, especially with respect to transaction fees. We may be required to adjust pricing to respond to actions by new or existing competitors, which could adversely impact our business, financial condition and operating results. We also compete with respect to the pricing of market data and value-added market data, such as historical market data. In our options segment, the pricing model for trade execution has changed in response to competitive market conditions, and our competitors have adjusted transaction fees and fee structures accordingly, including by opening new exchanges, which allow them to offer multiple pricing models that can appeal to different segments of market participants. These changes have resulted in significant pricing pressures on us, especially on transaction fees and incentives for multi-listed products. As a result of these pricing pressures, our average rate per multi-listed options contract may decrease. It is likely that this pressure will continue and even intensify as our competitors continue to seek to increase their share of trading by further reducing their transaction fees or by offering other financial incentives to order providers and liquidity providers to induce them to direct orders to their markets. In addition, one or more competitors may engage in aggressive pricing strategies and significantly decrease or completely eliminate their profit margin for a period of time in order to capture a greater share of trading volume. Some order-providing firms on our exchanges have taken ownership positions in options exchanges that compete with us and such exchanges have given those firms added economic incentives to direct orders to them. 27 Table of Contents With respect to our proprietary products, we compete with futures exchanges and swap execution facilities that offer similar products and other financial market participants that offer over-the-counter derivatives. We also compete against certain multi-listed options products, including SPY, which offer some of the features of our proprietary products. To attract market share, we may offer “inverted” pricing specials or no-transaction fee trading from time to time. BZX also offers a “cross-asset add volume tier” that gives a bigger rebate for additional volume on both the BZX equities and options platforms. These forms of promotions may adversely affect our profitability. If we are unable to compete successfully with respect to the pricing of our services and products, our business, financial condition and operating results may be adversely affected. We could lose a substantial percentage of our share of trading if we are unable to price transactions in a competitive manner. Also, our profits could decline if competitive pressures or regulatory changes, such as the transaction fee pilot, force us to reduce fees. A significant portion of our operating revenues is generated by our transaction-based business. If the amount of trading volume on our exchanges decreases, or the product mix shifts to lower revenue products, our revenues from transaction fees will most likely decrease. In 2019, approximately 62.9% of our net revenues were generated by our transaction-based business. This business is dependent on our ability to attract and maintain order flow, both in absolute terms and relative to other market centers. If the amount of trading volume on our exchanges, CFE or notional value traded on Cboe FX, Cboe SEF and Cboe Europe Equities exchanges decreases, we are likely to see a decrease in transaction fees. Our total trading volumes could decline if our market participants reduce their trading activity for any reason, such as: ● heightened capital requirements;Trade Alert. ● transaction tax; In 2021, we started to provide data services to market participants globally through Cboe Global Cloud with a plan to disseminate most of Cboe’s real-time market data and analytics products via the cloud as an additional distribution channel. ● regulatory or legislative actions; ● reduced need to trade due to changes in volatility and/or passive investment trends; ● reduced access to capital required to fund trading activities; ● consolidation among market participants; or ● significant market disruptions. Over the past few years, a number of legislative actions have been taken, both domestically and internationally, that may cause market participants to be subject to increased capital requirements and additional compliance burdens. These actions, including the Collins Amendment to Dodd-Frank, MiFID II and MiFIR, may cause market participants to reduce trading activity on our exchanges. In addition, the transaction fees generated are different based on type of product and other factors, including the type of customer and certain volume discounts. If the amount of our trading volume decreases, the mix traded shifts to our lower revenue per contract products or the transaction fee pilot is implemented, our revenues from transaction fees will most likely decrease. We can offer no assurance that we would be able to reduce our costs to match the amount of any such decrease. Revenues from our market data fees and access and capacity fees may be reduced due to declines in our market share, trading volumes or regulatory changes. The occurrence of any event that reduces the amount of market data fees that we receive, whether as a result of fee reductions, fewer members subscribing to the U.S. tape plans, declines in market share or trading volumes (or notional volume in the case of Cboe Europe Equities) or regulatory changes, will have a direct negative impact on our business, financial condition and operating results. For example, if our market share of U.S. listed equities and options, or Cboe’s European equities trading, were to decline, our share of market data fees could also decline. Moreover, market data fees could decline as a result of a reduction in the numbers of market data users, for example because of consolidation among 28 Table of Contents market data subscribers or due to a decline in professional subscriptions as a result of staff reductions in the financial services industry or otherwise. Regulatory and legal developments could also impact the fees we receive from market data and access and capacity, or our cost in providing such services. In the U.S., we are generally required to file with the SEC any changes to the fees that we charge for our securities market data products and access and capacity fees. In recent years, certain industry groups have objected to the ability of exchanges to charge for certain market data products. Specifically, the Securities Industry and Financial Markets Association (“SIFMA”) has filed a number of denial of access applications with the SEC to set aside proposed rule changes to establish or modify fees for our market data products, access and capacity fees and related services. Further, the SEC and some media have scrutinized market data and market access. An adverse ruling in these matters or additional scrutiny could cause the SEC to more closely examine exchange market data and access and capacity fees, which in turn could result in our having to reduce the fees we charge for market data and access and capacity and there could be a negative impact on our revenues. See “Legal Proceedings” for more information. In addition, as discussed above, in January 2020, the SEC issued for public comment the Proposed Order that would require U.S. equities exchanges and FINRA to develop and file a new consolidated data plan. If a final order were to be issued, it may have a negative impact on the market data fees we charge and there could be a negative impact on our revenues. We believe Cboe Europe Equities currently offers market data to customers on a non-discriminatory basis at a reasonable cost. As regulators determine how market data should be disaggregated and what is a reasonable commercial basis for providing market data, it could affect our ability to offer market data products in the same manner that we do today thereby causing an adverse effect on our European market data revenues. While MiFID II and MiFIR aim to encourage a commercial solution to a consolidated tape in Europe, should this fail to materialize, policy makers might be encouraged to implement a mandatory solution that could impact our ability to develop our own commercial offering. Legislative or regulatory changes affecting our markets could have a material adverse effect on our business, financial condition and operating results. Changes in regulation by the SEC, CFTC, FCA, AFM, foreign regulators or other government action, including SEC approval of rule filings by other SROs or entities, including OCC, could materially affect our markets. In recent years, the securities and derivatives industries have been subject to regulatory changes as a result of increasing government and public scrutiny of the securities and derivatives industries. We have also experienced an increase in rulemaking and legislation that could affect our business. Starting in 2015, large U.S. banks were required to use a calculation methodology known as the current exposure method (“CEM”) to compute regulatory capital requirements associated with the clearing guarantee provided by bank-affiliated OCC clearing members. U.S. banks, as well as European banks that also apply CEM, are required to maintain regulatory capital that is disproportionate to the risk of clearing options contracts and has led to further increases in capital requirements for bank holding companies and bank subsidiaries involved in the trading and clearing of derivatives. In November 2019, the Board of Governors of the Federal Reserve, the Federal Deposit Insurance Corporation, and the Office of the Comptroller of the Currency approved replacing CEM with a more risk-sensitive calculation method known as the standardized approach to counterparty credit risk (“SA-CCR”), which is expected to reduce capital requirements associated with the clearing of listed options. Banks are required to adopt SA-CCR by January 1, 2022, but may do so as early as April 1, 2020. If the implementation of SA-CCR does not occur earlier than 2022, during that time we may experience a reduction in trading in options and futures due to bank-affiliated clearing members charging their customers more to trade, reducing the type or number of customers or withdrawing from the business of market-maker clearing. Further, Congress, regulators and some media have been increasingly scrutinizing electronic trading and the structure of equity markets in recent years. The SEC continues to consider various potential market structure changes, which could result in reduced trading volumes, or which could negatively affect our business. To the extent the SEC adopts regulatory changes, our business, financial condition and operating results could be negatively impacted. In addition, high frequency trading has been the subject of private litigation and we are party to one such matter. See Note 29 Table of Contents 24 (“Commitments, Contingencies, and Guarantees—Legal Proceedings”) for more information. To the extent the SEC adopts regulatory changes related to market data and access and capacity, such as the Proposed Order, our business, financial condition and operating results could be negatively impacted. In addition, as discussed above, in December 2018, the SEC approved the transaction fee pilot. The transaction fee pilot may cause Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or challenge the transaction fee pilot and it may have a material impact on our business, financial condition and operating results if, for example, shifts in order flow away from exchanges were to occur. See “Legal Proceedings” for more information. Under E.U. regulations, European banks and other European financial institutions become subject to punitive capital charges if they transact options or futures through a non-qualifying clearinghouse. OCC, our clearinghouse for options and futures, is not currently recognized as a qualified clearinghouse by the E.U.; however, the OCC is working with the E.U. to qualify as a foreign clearinghouse equivalent. As a prerequisite to becoming qualified, OCC could be required by the E.U. to contribute significant capital to its default waterfall applicable in the event of clearing member default. This capital could be required to be drawn before the default fund contributions of non-defaulting clearing members in the event that a defaulting clearing member’s margin and other contributions were to be exhausted. OCC’s stockholders, including Cboe Options, could effectively be required to fund this capital. If the E.U. does not recognize OCC as a qualified clearinghouse by June 15, 2021 (or by a subsequent date in the event that the current deadline is extended), then European market participants that clear through OCC would become subject to punitive capital charges. As a result, we could experience the loss of a significant number of European market participants and a significant reduction in trading activity on our options and futures markets, which could have a material adverse effect on our business, financial condition and operating results. The implementation of MiFID II and MiFIR in Europe at the beginning of 2018 has encouraged competition among market centers in Europe. MiFID II and MiFIR have introduced a number of new rules, including enhanced internal organizational and compliance monitoring requirements, which apply directly to European trading venues such as our MTF and RM. The impact of MiFID II and MiFIR is significant, and the increased competition among market centers could reduce trading volumes and trading fees, while increasing our costs of operating in Europe. Additionally, European authorities are planning to review MiFID in 2020 as a result of which new rules may come into effect that could have a material impact on our business. The legislative and regulatory environment in which the spot FX market operates is evolving and has undergone significant changes in the recent past, and there may be future regulatory changes in the spot FX industry. The FX Global Code was published in 2017 and sets forth standards of conduct agreed by market participants and central banks on a global basis to apply to the wholesale FX market, and the effect of its publication on conduct and future regulation continues to evolve. Changes in the interpretation or enforcement of existing laws and regulations by applicable governmental bodies and regulatory organizations, or the adoption of new legal or regulatory requirements, may also adversely affect our spot FX business.  Further, our FX non-deliverable forwards business may also be adversely affected by proposed regulatory changes to the rules governing swap execution facilities.   It is also possible that there will be additional legislative and regulatory changes or efforts in the environment in which we operate our businesses. Actions on any of the specific regulatory issues currently under review in the U.S. or Europe and other proposals could have a material impact on our business. In addition, U.S. and foreign legislatures and regulators and other regulatory authorities could impose legislative or regulatory changes that could adversely impact the ability of our market participants to use our markets or participate in the securities industry at all. Any such changes could result in the loss of a significant number of market participants or a reduction in trading activity on our markets, either of which could have a material adverse effect on our business, financial condition and operating results. Changes or proposed changes in regulation may also result in additional costs of compliance and modification of market participants’ trading activity on our exchanges and markets. 30 Table of Contents The technology upon which we rely, including those of our service providers, may be vulnerable to security risks, cybersecurity risks, insider threats, unauthorized disclosure of confidential information, operational disruptions, and other risks and events that could harm our business. The secure and reliable operation of our technology, including our computer systems and communications networks, and those of our service providers and market participants, is a critical element of our operations. These systems and networks may be subject to various cybersecurity incidents, improper or inadvertent access to or disclosure of confidential, commercially sensitive, or personally identifiable information, data theft, corruption or destruction, cyber-attack, malware and other security problems, as well as acts of terrorism, natural disasters, human error, criminal insider activity, power loss and other events that are beyond our control. For example, in 2018, we discovered and in 2018 and 2019 we investigated an incident involving a suspected theft of computer servers and networking devices. We currently maintain physical, technical, and administrative safeguards to protect the confidentiality, integrity, availability and reliability of our systems, networks and information more broadly, and to guard against cybersecurity incidents and unauthorized access. We also maintain and continue to enhance policies, procedures and controls for tracking and appropriately disposing of technology equipment hardware during technology updates and around the protection of our computer systems and communications networks. Collectively, these safeguards and measures may prove inadequate to prevent the attendant risk posed by cybersecurity incidents, subjecting us to contractual restrictions, liability and damages, loss of business, penalties, unfavorable publicity, and increased scrutiny by our regulators, and materially impacting our financial condition and operating results. We may be required to expend significant resources in the event of any real or threatened breaches in security or system failures, including to protect against threatened breaches, to alleviate harm caused by an actual breach, and to address any reputational harm or litigation or regulatory liability. Such harms also could cause us to lose market participants, experience lower trading volume, and negatively impact our competitive advantage and business, financial condition and operating results. Additionally, as threats continue to evolve and increase, and as the regulatory environment related to information security, data collection and use, and privacy becomes increasingly rigorous, we may be required to devote significant additional resources to modify and enhance our security controls and to identify and remediate any security vulnerabilities, which could have an adverse effect on our business, financial condition and operating results. Intense competition could materially adversely affect our market share and financial performance. The market for trade execution services and products is intensely competitive in the asset classes and geographies in which we operate. Increased competition may result in a decline in our share of trading activity and a decline in our revenues from transaction fees and market data fees, thereby adversely affecting our operating results. We compete with a number of entities on several different fronts, including the cost, quality and speed of our trade execution, functionality and ease of use of our trading platform, range of our products and services, our technological innovation and adaptation and our reputation. See “Business – Competition.” Some of our competitors and potential competitors have greater financial, marketing, technological, personnel and other resources than we do. These factors may enable them to develop similar or more innovative products, to offer lower transaction fees or better execution to their customers or to execute their business strategies more quickly or efficiently than we can. In addition, our business, financial condition and operating results may be adversely affected if we cannot successfully develop, introduce and/or market new services and products or if we need to adopt costly and customized technology for our services and products. Furthermore, new or existing competitors may: ● respond more quickly to competitive pressures; ● develop products that compete with our products or are preferred by our customers; ● offer products and services at prices below ours to gain market share and to promote other businesses; ● develop and expand their technology and service offerings more efficiently; ● provide better, more user-friendly and more reliable technology; ● take greater advantage of acquisitions, alliances and other opportunities; 31 U.S. Tape Plans We also derive a portion of our revenue from market data fees from U.S. tape plans, including Unlisted Trading Privileges (“UTPs”), the Consolidated Tape Association (“CTA”) and OPRA. Fees, net of plan costs, from UTP, CTA, and OPRA are allocated and distributed to plan participants like us according to their share of tape fees based on a formula, required by Regulation NMS, which may take into account both trading and quoting activity. Our Market Models We operate a variety of derivatives and cash and spot markets. Our markets use a combination of pricing and market models to differentiate them from each other and from our competitors. For our U.S. derivatives options markets, Cboe Options is a hybrid market combining open outcry floor trading with electronic trading. For multi-listed products, we utilize public customer priority, market turner in certain products, participation rights and pro-rata allocation market models, combined with the “classic” pricing model. Under the classic pricing model, professional participants pay transaction fees, public customers generally do not pay transaction fees and market makers compensate brokers for sending order flow to the exchange (known as payment for order flow). For proprietary products, we use price-time or pro-rata allocation, sometimes with public customer priority, and market turner market models, combined with a pricing model where all market participants generally pay fees. Our other three options markets are fully electronic. BZX options utilizes a price-time market model, combined with a “maker-taker” pricing model. Under the maker-taker pricing model, market participants who make the market (a “maker”) generally receive a rebate, while market participants who trade against those markets (a “taker”) pay a transaction fee. EDGX options utilizes customer priority, participation rights and pro-rata allocation market models, combined with the classic pricing model. C2 options utilizes a pro-rata allocation market model, combined with the maker-taker pricing model. For our U.S. derivatives futures market, which is fully electronic, CFE utilizes a price-time market model, combined with a pricing model where all market participants generally pay fees, subject to specified exceptions. For our cash and spot markets, the U.S. equities exchanges, which are fully electronic, offer various market models. BZX equities utilizes a price-time market model, combined with the maker-taker pricing model. EDGX equities utilizes a price-time with retail priority market model, combined with the maker-taker pricing model. BYX equities utilizes a price-time with price improvement for retail customers market model, combined with the “taker-maker” pricing model. Under the taker-maker pricing model, market participants who make the market pay a transaction fee, while market participants who trade against those markets receive a rebate. EDGA equities utilizes a price-time market model, combined with a taker-maker pricing model. In addition to these market models, each of the U.S. equity exchanges provides numerous specific order types that are designed to enhance their respective market models. For our cash and spot markets, MATCHNow, the Canadian equities ATS, which is fully electronic, utilizes a model that combines frequent call matches and continuous execution opportunities in a confidential trading book. The system uses real-time quotes for protected transparent Canadian markets, and orders may be firm or conditional. Firm orders matched within MATCHNow are executed at three levels of price improvement: (1) the mid-point between the Canadian best bid and offer (the “CBBO”); (2) one price increment better than the CBBO or; (3) at the bid or offer for orders that meet a specified large threshold. Trading fees are typically calculated as a function of trade volume and share price. In Europe, following the implementation of the Directive on Markets in Financial Instruments (Directive 2014/65/EU) (“MiFID II”), for the derivatives and cash and spot markets, rebates are generally available if they are tied to a market making scheme or specific service. For our cash and spot markets, BIDS Trading, the U.S. equities ATS market, which is fully electronic, utilizes a sponsored access model to provide anonymous executions in NMS stocks. BIDS Trading provides numerous order types, including both firm and conditional orders. All orders matched within BIDS Trading are executed at or better than the 13 Table of Contents ● market, promote, bundle and sell their products and services more effectively; ● leverage existing relationships with customers and alliance partners more effectively or exploit brand names to market and sell their services; and ● exploit regulatory disparities between traditional, regulated exchanges and alternative markets, including over-the-counter markets, that benefit from a reduced regulatory burden and lower-cost business model. If our products, markets, services and technology are not competitive or we fail to anticipate or respond adequately to changes in technology, customer preferences and regulatory requirements or any significant delays in product development efforts our business, financial condition and operating results could be materially harmed. We depend on third-party service providers for certain services that are important to our business. An interruption, significant increase in fees or cessation or impairment of such service by any third party could have a material adverse effect on our business, financial condition and operating results. We depend on a number of service providers, including clearing organizations such as OCC, NSCC, LCH, EuroCCP and SIX x-clear; securities information processors such as the CTA, UTP Securities Information Processor and OPRA; regulatory and other service providers such as FINRA, NFA and OCC; the hosts of our data and disaster recovery centers; and various vendors of communications and networking products and services. In addition, we also depend on third party routing and clearing firms who are involved in processing transactions on our behalf. More specifically: ● If OCC, NSCC, EuroCCP, LCH and SIX x-clear were unable to perform clearing services for existing or new products, or their clearing members were unable or unwilling to clear through them, transactions could likely not occur on our markets or there may be delays, including until clearing is moved to another clearing agency. In 2019, approximately 64.8% of our net transaction fees were generated by options and futures that were cleared through OCC. ● OPRA, UTP Securities Information Processor and the CTA consolidate options and equities market information such as last sale reports and quotations. If any of them were unable to provide this information for a sustained period of time, we may be unable to offer trading on our options and equities markets. ● We are heavily dependent on technology for our markets, including our data and disaster recovery centers, some of which are housed by third parties, and certain communications and networking products and services. If this technology is unavailable, and cannot be replaced in a sufficiently short time period, we may be unable to operate our markets. ● We plan to utilize Amazon Web Services (“AWS”) to maintain secondary offsite backups of our and our customers’ data and may utilize AWS in the future for additional services. We do not control the operations of AWS or their facilities and may be vulnerable to disruptions in our access to the platform as a result of a number of potential causes, including technical failure, natural disasters, fraud or security attacks that we cannot predict or prevent. Additionally, any vulnerability of AWS could expose our or our customers’ confidential data, which could result in harm to our business reputation. ● FINRA, OCC, and NFA provide certain regulatory services and functions for our options, equities and futures exchanges, while we retain regulatory responsibilities for such services. If FINRA, OCC, or NFA stopped providing services, or provided inadequate services, we may be subject to action by the SEC or CFTC, or may have limitations placed upon our markets. ● We rely on FINRA to provide services for the implementation of the CAT. If FINRA stops providing services or provides inadequate services, we and the other execution venues may incur regulatory liability including enforcement action by the SEC or limitations placed upon our markets. In addition, until the SEC approves a funding model that shares the cost of the CAT between the SROs and industry members, the SROs may continue to incur additional significant costs, including as a result of replacing the plan processor, or result in not being able to collect on the promissory notes related to the funding of the implementation and operation of the CAT. ● We rely on third party routing and clearing firms to clear trades in U.S. listed equity securities routed by us to other markets, and to execute trades in options that we route to other markets.  32 Table of Contents With respect to options, all contracts traded on our exchanges must be cleared through clearing members of OCC. At December 31, 2019, there were 98 TPHs that are clearing members of OCC. Two clearing members accounted for approximately 48.9% of transaction and other fees collected through OCC in 2019. The next largest clearing member accounted for approximately 16.6% of transaction and other fees collected through OCC. Additionally, the two largest clearing members clear the majority of the market-maker sides of transactions at Cboe Options, C2, BZX, EDGX and at all of the options exchanges. Should one of these clearing members or liquidity providers exit the business or withdraw from our options exchanges, impose additional market-maker financial requirements or if market-makers were unable to transfer to another clearing member or other liquidity providers were unable to provide additional liquidity, this could create a significant disruption to the options markets, including ours. We cannot provide assurance that any of these providers will be able to continue to provide these services in an efficient manner or that they will be able to adequately expand their services to meet our needs. An interruption or malfunction in or the cessation or impairment of an important service by a third party or disruption of a third party’s operations could cause us to halt trading in some or all of our products or our services, make us unable to conduct other aspects of our business, cause us to experience the loss of a significant number of market participants or cause us to experience a significant reduction in trading activity on our options and futures markets, each of which could have a material adverse effect on our business, financial condition and operating results. In addition, our inability to make alternative arrangements, such as moving clearing to another clearing agency, in a timely manner, or at all, could have a material adverse impact on our business, financial condition and operating results. Our operations outside of the U.S. expose us to currency risk. In addition to our operations in the U.S., we have operations in the U.K., continental Europe, Ecuador, Hong Kong and Singapore. We, therefore, have exposure to exchange rate movements between the British pound, the Euro, the Hong Kong dollar, and the Singapore dollar against the U.S. dollar. Significant inflation or changes in foreign exchange rates with respect to one or more of these currencies could occur as a result of general economic or political conditions, acts of war or terrorism, changes in governmental monetary or tax policy, Brexit or changes in local interest rates. These exchange rate differences will affect the translation of our non-U.S. results of operations and financial condition into U.S. dollars as part of our consolidated financial statements. If one or more of the index providers from which we have licenses or service providers with respect to proprietary products fails to maintain the quality and integrity of their indices or fails to perform under our agreements with them or if customer preferences change, or if we fail to maintain the quality and integrity of our proprietary indices, revenues we generate from trading in these proprietary products or the calculation and dissemination of index values may suffer. We are a party to a number of license agreements pursuant to which we may list for trading securities options on various indices including license agreements that we have with S&P, for the S&P 500, S&P 100 and S&P Select Sectors Indices, DJIA, LSEG and MSCI. These license agreements provide that we are authorized to list products based on their indices, and some of the resulting index options and futures are among the most actively traded products on our exchanges. We also enter into licensing agreements pursuant to which we calculate and disseminate values of proprietary indices. The quality and integrity of each of these indices are dependent on the ability of the index providers, including us, to maintain the index, including by means of the calculation and rebalancing of the index, and are dependent on the index providers for a number of things, including the provision of index data. We also rely on index providers to enforce intellectual property rights against unlicensed uses of the indices and uses of the indices that infringe on our licenses. Furthermore, some of our agreements concerning our proprietary products provide for the parties to those agreements to provide important services to us. If any of our index providers, including us, are unable to maintain the quality and integrity of their indices, or if any of the index providers or service providers fail to perform their obligations under the agreements, trading in these products, and therefore transaction fees we receive, may be adversely affected or we may not receive the financial benefits of the agreements that we negotiated. 33 Table of Contents We and our licensors may not be able to protect our respective intellectual property rights. We rely on patent, trade secret, copyright and trademark laws, the law of the doctrine of misappropriation and contractual protections to protect our proprietary technology, proprietary products, index methodologies and other proprietary rights. In addition, we rely on the intellectual property rights of our licensors in connection with our listing of exclusively-licensed index options and futures products. We and our licensors may not be able to prevent third parties from copying, or otherwise obtaining and using, our intellectual property without authorization, listing our proprietary or exclusively-licensed index products without licenses or otherwise infringing on our rights. We and our licensors may have to rely on litigation to enforce our intellectual property rights, determine the validity and scope of the proprietary rights of others or defend against claims of infringement or invalidity. We and our licensors may not be successful in this regard. Such litigation, whether successful or unsuccessful, could result in substantial costs to us, diversion of our resources or a reduction in our revenues, any of which could materially adversely affect our business. Any infringement by us on intellectual property rights of others could result in litigation and could have a material adverse effect on our operations. Our competitors, as well as others, have obtained, or may obtain, patents or may otherwise hold intellectual property rights that are related to our technology or the types of products and services we offer or plan to offer. We may not be aware of all intellectual property that may pose a risk of infringement by our products, services or technologies. In addition, some potential patent applications in the U.S. are confidential until a patent is issued, and therefore we cannot evaluate the extent to which our products, services or technologies may be covered or asserted to be covered in pending patent applications. Thus, we cannot be sure that our products, services or technologies do not infringe on the rights of others or that others will not make claims of infringement against us. Claims of infringement are not uncommon in our industry, and even if we believe that such claims are without merit, they can be time-consuming and costly to defend and divert management resources and attention. If one or more of our products, services or technologies were determined to infringe a patent or other intellectual property right held by another party, we may be required to pay damages, stop using, developing or marketing those products, services or technologies, obtain a license from the intellectual property rights holders, or redesign those products, services or technologies to avoid infringement. If we were required to stop using, developing or marketing certain products, services or technologies, our business, financial condition and operating results could be materially harmed. Moreover, if we were unable to obtain required licenses, we may not be able to redesign our products, services or technologies to avoid infringement, which could materially adversely affect our business, financial condition and operating results. If we fail to attract or retain highly skilled management and other employees our business may be harmed. Our success largely depends on the skills, experience and continued efforts of management and other key personnel. As a result, to be successful, we must retain and motivate executives and other key employees. However, we have no assurances that these employees will remain with us. The roles and responsibilities of departing executive officers and employees will need to be filled either by existing or new officers and employees, which may require us to devote time and resources to identifying, hiring and integrating replacements for the departed executives and employees that could otherwise be used to pursue business opportunities, which could have a material adverse effect on our overall business, financial condition and operating results. There is substantial competition for qualified and capable personnel in the technology space, which may make it difficult for us to retain and recruit qualified employees in sufficient numbers. If we fail to retain our current employees, it would be difficult and costly to identify, recruit and train replacements needed to continue to conduct and expand our business. In particular, failure to retain and attract qualified technology personnel could result in systems failures. Consequently, our reputation may be harmed, we may incur additional costs and our profitability could decline. There can be no assurance that we will be able to retain and motivate our employees in the same manner as wehave historically done. Additionally, effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving our management team and key employees could hinder our strategic planning and execution. 34 Table of Contents Computer and communications systems failures and capacity constraints could harm our reputation and our business. Our business depends on the integrity and performance of our computer and communications systems. If our systems cannot expand to cope with increased demand or otherwise fail to perform, we could experience unanticipated disruptions in service, slower response times and delays in the introduction of new products and services. These consequences could result in trading outages, lower trading volumes, financial losses, decreased customer service and satisfaction and regulatory sanctions and could have a material adverse effect on our ability to conduct our business. Although we have a back-up plan of significant trading and key corporate systems, the back-up systems or disaster recovery plans may prove to be inadequate in the event of a systems failure or cyber-security breach. Despite having disaster recovery facilities, there can be no guarantees that we will be able to open an efficient, transparent and liquid marketplace, if we can open at all, following a systems failure. Moreover, with extended trading hours, we have to operate our systems longer and have fewer non-trading hours to address any potential concerns with the systems on which we rely. Our markets have experienced occasional systems failures and delays in the past and in the future our systems may fail, in whole or in part, or may operate slowly, causing one or more of the following: ● unanticipated disruption in service to our participants; ● failures or delays during peak trading times or times of unusual market volatility; ● slower response times and delays in trade execution and processing; ● incomplete or inaccurate accounting, recording or processing of trades; and ● distribution of inaccurate or untimely market data to participants who rely on this data in their trading activity. Any of these events may cause: ● a loss in transaction or other fees due to the inability to provide services for a time; ● requests by market participants or others that we reimburse them for financial loss, either within the constraints of the limited liability provisions of our exchanges’ rules or in excess of those amounts; ● trading volume to diminish on our exchanges due to dissatisfaction with the platform; and ● one or more of our regulators to investigate or take enforcement action against us. As a consequence of any of these events, our business, financial condition and results of operations could suffer materially. In addition to other measures, we test our systems to confirm whether they will be able to handle anticipated present and future peak trading activity or times of unusual market volatility. However, we cannot assure you that our estimates of future trading volume will be accurate or that our systems will always be able to accommodate actual trading volume without failure or degradation of performance. We anticipate that we will need to continue to make significant investments in hardware, software and telecommunications infrastructure to accommodate the increases in traffic. If we cannot increase the capacity and capabilities of our systems to accommodate increasing trading activity and to execute our business strategy, our ability to maintain or expand our businesses would be adversely affected. Misconduct by our TPHs, members, participants or others could harm us. We run the risk that our TPHs, members, participants or other persons who use our markets or our products or our employees may engage in fraud, market or product manipulation or other misconduct, which could result in regulatory sanctions and serious harm to our reputation, especially because we are the parent company of SROs. It is not always possible to deter misconduct, or market or product manipulation, and the precautions we take to prevent and detect this activity may not be effective in all cases. In addition, misconduct, or market or product manipulation by, or failures of, 35 Table of Contents participants on our or other exchanges may discourage trading on our exchanges or of our products, which could reduce revenues. Our use of open source software code may subject our software to general release or require us to re-engineer our software, which could harm our business. Our technology platform uses open source software code. Companies that incorporate open source software into their products have, from time to time, faced claims challenging the ownership of open source software. As a result, we could be subject to suits by parties claiming ownership of what we believe to be open source software. In addition, some open source software licenses require users who distribute open source software as part of their software to publicly disclose all or part of the source code in their software and make any derivative works of the open source code available on unfavorable terms or at no cost. Open source license terms may be ambiguous, and many of the risks associated with usage of open source software cannot be eliminated. We believe that our use of open source software is in compliance with the relevant open source software licenses and does not require disclosure of any of our source code. However, if we were found to have inappropriately used open source software, we may be required to release our proprietary source code, re-engineer or discontinue use of our software or take other remedial action any or all of which could cause disruptions in, or impose significant costs on, our business. Potential conflicts of interest between our for-profit status and our regulatory responsibilities may adversely affect our business. As a for-profit business with regulatory responsibilities, we are responsible for disciplining TPHs and members for violating our rules, including by imposing fines and sanctions. This may create a conflict of interest between our business interests and our regulatory responsibilities. Any failure by us to fulfill our regulatory obligations could significantly harm our reputation, increase regulatory scrutiny or cause the SEC or CFTC to take action against us, all of which could adversely affect our business, results of operations or financial condition. Brexit could have a negative impact on the U.K. and E.U. economies and lead to considerable uncertainty while new treaties are negotiated. In addition to the economic uncertainty the Brexit Vote, Brexit and Transition Period bring, there are a number of potential risks that investors should consider: NBBO. BIDS Trading charges fees based on disclosed, objective criteria: (i) means of access; (ii) the type of order; and (iii) the total volume of executions during the calendar month. ● Political uncertainty. Following the Brexit Vote, the U.K. entered into a period of acute political uncertainty both as to the nature and timing of the negotiations with the E.U. Such uncertainty led to a high degree of economic and market disruption and legal uncertainty. While some certainty has been established following the joint U.K./E.U. approval of the Withdrawal Agreement, including the agreement of a Transition Period up to the end of 2020, it is not possible to predict the outcome of trade negotiations and the impact they will have on the U.K. in general and markets more broadly. ● Legal uncertainty. A significant proportion of English law currently derives from or is designed to operate in concert with E.U. law. This is especially true of English law relating to financial markets, financial services, prudential and conduct regulation of financial institutions, bank recovery and resolution, payment services and systems, settlement finality, and market infrastructure. Depending on the terms of the U.K.’s exit from the E.U. entered into during the Transition Period, significant changes to English law are likely, and we cannot predict what these changes will be and how they may affect our business. ● Regulatory uncertainty. There is significant uncertainty about how the remaining E.U. countries (“EU27”) financial institutions with assets (including branches) in the U.K. and U.K. financial institutions with assets in the EU27 will be regulated. At present, E.U. single market regulation allows regulated financial institutions (including credit institutions, investment firms, alternative investment fund managers, insurance and reinsurance undertakings) to benefit from a passporting system for regulatory authorizations required to conduct their businesses, as well as facilitating mutual rights of access to important elements of market infrastructure 36 In Australia, for our derivatives and cash and spot markets, Cboe Australia, a regulated stock exchange, which is fully electronic, utilizes a model that charges a different ad valorem fee rate depending on whether a participant is making or taking liquidity. Fee waivers are also provided to participants registered as market makers, but payments for order flow are prohibited. In Japan, for our cash and spot markets, Cboe Japan, offers two fully electronic displayed markets, Chi-Alpha, which utilizes a price-time market model, combined with the “maker-taker” pricing model and Chi-Select, which utilizes a price-time retail customers focused market model, combined with the “taker-maker” pricing model. Cboe Japan also offers two fully electronic non-displayed markets, Chi-Match, which matches VWAP orders during pre-market hours and Kai-X, which utilizes a price-time market model aiming for primary market mid-point trades. For our FX spot markets, the Cboe FX platform utilizes a price-firmness-time priority market model, combined with a pricing model where users are charged either a flat or tiered commission rate based upon the notional amount traded on the platform. For our FX NDF markets, Cboe SEF and Cboe Swiss platforms utilize a price-firmness-time priority market model and charge a flat commission based upon the notional amount traded on the platform and the capacity in which a participant is trading. Our markets also charge fees for the opportunity to trade or access our markets, including fees for trading-related functionality. To facilitate trading, we also charge fees for certain technology services, terminal and other equipment rights, maintenance services, trading floor space and telecommunications services. Listing Cboe serves as a listing destination for ETPs in the U.S., the UK, Europe and Australia, and its markets are structured and designed for ETP issuers and their investors. In 2021, Cboe added 121 ETP listings in the U.S. and won 25% of all new U.S. ETP listings. There are now 643 ETPs globally listed on Cboe from 84 different issuers. We offer fully-automated opening, closing and halt reopening auctions for our listed securities, which are designed to maximize the efficiency of the price discovery process. Clearing Our subsidiary EuroCCP, a European central counterparty (“CCP”), provides post-trade services, including clearing, to stock exchanges, multilateral trading facilities and for over-the-counter equities trades and derivatives trades. EuroCCP acts as a central counterparty that, for its clearing participants, becomes the buyer to every seller and the seller to every buyer. As a result, it guarantees the timely performance of the obligations of buyers and sellers and takes on the risk of the performance of the transactions that it clears. Additionally, as a critical Financial Market Infrastructure, EuroCCP is subject to strict business continuity requirements and regulatory oversight. In 2021, EuroCCP provided CCP protection for an average of €43 billion of cleared value on a daily basis. Through the process of netting, in 2021, EuroCCP eliminated 72%, or €31 billion of the average daily cleared value, leaving an average daily settlement value of €12 billion. In 2020, EuroCCP provided CCP protection for an average of €41 billion of cleared value on a daily basis. Through the process of netting, in 2020, EuroCCP eliminated 80%, or €30 billion of the average daily cleared value, leaving an average daily settlement value of €11 billion. Customers Our customers generally include financial institutions, trading platforms, institutional and individual investors, and professional traders. Our equities and options customers in the United States include trading permit holders and members of Cboe Options, C2, BZX, BYX, EDGX, and EDGA, which are SEC-registered broker-dealers, and the customers of those broker-dealers. Our Canadian equities customers include subscribers of MATCHNow, which are Canadian registered investment dealers, and certain clients of those dealers. Our Australian customers include trading participants of Cboe Australia, which are Australian registered investment dealers, and certain clients of those dealers. Our Japanese customers include participants of Chi-Alpha, Chi-Select, Chi-Match and Kai-X, which are Japanese registered broker-dealers, and certain clients of those dealers. Our ATS equities participants in the United States include subscribers of BIDS Trading, which are SEC-registered broker-dealers, and certain customers of those broker-dealers. Our futures customers include banks, futures commission merchants and their customers, hedge funds, asset managers, proprietary trading firms, and Commodity Trading Advisors. Similarly, our equities’ customers in Europe are European Union (“EU”) 14 Table of Contents such as payment and settlement systems. E.U. law is also the framework for mutual recognition of bank recovery and resolution regimes. regulated brokerage and proprietary trading firms, as well as sponsored access clients of these brokerage firms and certain non-EU regulated and unregulated direct access participants. EuroCCP clears equities, equity like instruments from 18 European markets and from the United States. EuroCCP also clears equity derivative instruments as traded on Cboe NL. EuroCCP clearing participants include EEA regulated banks and brokerage trading firms. Our institutional global FX customers include banks, broker-dealers, hedge funds, asset managers, proprietary trading firms, Commodity Trading Advisors, and corporates. Access to our markets and trading rights and privileges depend upon the nature of the customer, such as whether the individual or firm is (or is eligible to become) a trading permit holder, trading privilege holder, member, participant, or subscriber of one of our markets. Competition The industry in which we operate is intensely competitive. We believe we face competition on a number of factors, including: ● price, quality and speed of our trade and clearing execution; Once the U.K. ceases to be a member state ● functionality and ease of the E.U., the current passporting arrangements are expected to cease to be effective, as will the current mutual rightsuse of our trading and clearing platforms; ● reliability, integrity, range and functionality of our products and services; ● integrity of our marketplaces; ● technological innovation and adaption; ● our brand awareness; and ● our reputation. We believe that we compete favorably with respect to these factors through a variety of methods, including: ● offering access to a broad array of products and services, including proprietary products and market infrastructure and current arrangements for mutual recognition of bank recovery and resolution regimes. The ability of regulated financial institutions to continue to do business between the U.K. and the EU27 after the U.K. ceases to be a member state of the E.U. would therefore be subject to separate arrangements between the U.K. and the EU27. There can be no assurance that there will be any such arrangements concluded and, if they are concluded, on what terms. ● Market uncertainty. Since the Brexit Vote and Brexit, there has been volatility and disruption of the capital, currency, exchange rates and credit markets. If this disruption continues, it may adversely impact our business, financial condition and operating results.data; In 2019, we derived 7.7% ● offering fee schedules and pricing models that both attract order flow and provide incentives to liquidity providers; ● providing advanced technology that offers broad functionality, low latency, fast execution, ease of our total net revenues from our U.K. operations. Depending on the outcome of the Brexituse, scalability, reliability and Transition Period negotiations, companiessecurity; ● offering efficient, transparent and liquid marketplaces; ● offering deep and liquid markets with operationsopportunities for price improvement; ● offering broad trading platform access in the U.K. may face unfavorable business conditions to access the single market. In preparation for Brexit, Cboe Europe Equities established a regulated entity in the E.U. in addition to its existing entity in the U.K. so that it can continue offering its services to customers in both jurisdictions. Nevertheless, if the E.U. or the U.K. introduce new legislation that could restrict free competition or access to capital markets, the impact of such legislation could have a material adverse effect on our business, financial condition and operating results. Damage to our reputation could have a material adverse effect on our business, financial condition and operating results. We believe one of our competitive strengths is our strong industry reputation. Various issues may give rise to reputational risk, including issues relating to: ● the representation of our business in the media; ● the quality and benefits of using our proprietary products, including the reliability and functionality of our transaction-based business and the accuracy of our market data; ��� the ability to execute our business plan, key initiatives or new business ventures and the ability to keep up with changing customer demands and regulatory initiatives; ● our regulatory compliance and our enforcement of compliance on our customers; ● the accuracy of our financial statements and other financial and statistical information; ● the quality of our corporate governance structure; ● the quality of our disclosure controls and internal controls over financial reporting, including any failures in supervision; ● the integrity and performance of our computer and communications systems; ● security breaches, including any unauthorized delivery of proprietary data to third parties; ● management of our outsourcing relationships, including our relationship with FINRA and NFA; ● any misconduct or fraudulent activity by our employees, especially senior management, or other persons formerly or currently associated with us; ● our listings business and our enforcement of our listing rules; and ● any negative publicity surrounding the ETPs that we serve as the listing destination.EU; Damage to our reputation could cause ● maintaining close relationships with customers; and ● providing customers with a reduction in the trading volumecomprehensive source of our proprietary products orinformation on our exchanges or cause us to lose customers. This, in turn, may have a material adverse effect on our business, financial conditionoptions and operating results. 37 Table of Contents If our risk management and compliance methods are not effective, our business, financial condition and operating results may be adversely affected. Our ability to comply with all applicable laws and rules is largely dependent on our establishment and maintenance of compliance, risk, audit, and reporting systems and procedures,ETPs as well as our abilityextensive options education. In our proprietary products, we compete against other futures exchanges and swap execution facilities that offer similar products, as well as against financial market participants that offer similar over-the-counter derivatives. We also compete against certain multi-listed options products, such as options on SPY, which may offer similar market exposure of our proprietary products, such as SPX options. The multi-listed options industry is extremely competitive. We expect this trend to continue. As of December 31, 2021, we compete with 12 U.S. options exchanges, in large part due to existing exchange holding companies opening new exchanges that offer different markets and pricing models on existing technology. Most of the equity and ETP options listed and traded on our exchanges are also listed and traded on the other exchanges. In addition, the options exchanges that we compete with set fees and rebates to attract multi-listed options business to their exchanges, which has historically reduced the net revenue per contract that we generate from multi-listed options, and the options exchanges that we compete with structure their options businesses in partnership with established market participants, such as consolidators, and other order flow providers, to increase their volume traded. Our U.S. listed equity securities and listing services and the BIDS Trading ATS compete against 12 other exchanges as of December 31, 2021, and several other ATSs and single dealer platforms. Market participants have multiple venues for the execution of orders, including national securities exchanges and numerous off-exchange venues, including other ATSs and broker-dealers who internalize orders off-exchange. Additionally, issuers have multiple venues for the listing of their products. In Canada, our equities ATS, MATCHNow, competes with several Canadian exchanges and other ATSs. In Australia, our exchange, Cboe Australia, competes with other Australian exchanges and ATSs. In Japan, our equities exchanges and ATSs, compete with several Japanese exchanges and other ATSs. 15 Table of Contents The market for execution and clearing services in Europe became more competitive following the introduction of MiFID II and the Regulation on Markets in Financial Instruments (Regulation (EU) No 600/2014) (“MiFIR”). Furthermore, MiFID II and MiFIR placed more onerous conditions on trading venues and investment firms and restricted certain types of trading activity. Our major competitors in Europe include national stock exchanges, other pan-European MTFs, European clearinghouses, dark pools, and systematic internalizers. The global FX market remains severely fragmented, with transparent automated marketplaces such as Cboe FX challenging a small number of similarly situated competitors. While the global FX market has experienced a shift from competing interbank platforms to ECNs, the electronification of the spot and NDF FX market may encounter resistance from customers that still prefer to utilize the phone, instant chats, terminals and key banking relationships for price discovery and trading. Furthermore, electronification of the FX market appears to be experiencing more resistance outside the United States. The electronic spot FX market is also intensely competitive, with over 10 other venues competing for market share as of December 31, 2021. Cboe measures and reports on market share against a narrower set of competitors, included in those venues. In addition, our data and access solutions face competition from other securities exchanges, technology companies, third-party market data providers, and information and software vendors, which have their own substantial market data distribution capabilities that serve as alternative means for receiving open market data feeds instead of connecting directly to our exchanges or trading venues. The sale of our proprietary data products is also under competitive threat from ATSs and trading venues that offer similar products. Distributors and consumers of our market data may also use our market data as an input into a product that competes against one of our traded or cleared products. Technology Cboe Trading Technology The trading platform for our equities, options, and futures markets is developed, owned, and operated in-house and is designed to optimize reliability, speed, scalability, and versatility. Each of our exchanges provide different market models, appealing to different user bases, and the trading technologies support all of them. Further, the technologies are designed to support many specialized features for each of the markets, such as: dark pools, trade reporting facility, systematic internalizer, Large-in-Scale, smart order routing, FLEX options, 24x5 trading, and hybrid trading (combining electronic and open outcry). In addition, Cboe and its applicable subsidiaries operate separate trading and/or clearing platforms, as applicable, for BIDS Trading, MATCHNow, EuroCCP, Global FX, Cboe Australia, and Cboe Japan. Our trading platforms have experienced very low operational downtime and low latency. The trading platforms use readily available hardware, thereby minimizing capital outlays required for each new market entry. Also, in order to continue to implement new enhancements to our trading platforms, new releases of software are generally deployed routinely in all of the applicable markets. Disaster Recovery We operate and maintain geographically diverse disaster recovery facilities for all of our markets. We expect that the disaster recovery facilities can be up and running in a short period of time and in certain instances we work with our market participants to try to quickly reopen marketplaces. We regularly test our data center recovery plans and periodically carry out weekend tests using our back-up data centers, as well as an annual test with our U.S. trading participants. In Canada, as required by local regulations, MATCHNow conducts internal testing of its disaster recovery data processing capabilities at least annually, and it participates in the bi-annual testing coordinated by IIROC. In Australia and Japan, Chi-X Asia Pacific conducts internal testing of its disaster recovery data processing capabilities at least annually. In Europe, we also regularly test our data center recovery plans and periodically carry out weekend tests which use our back-up data center, as well as an annual test with our European trading participants. We continue to work to improve both the availability of our technology and our disaster recovery facilities. Routing and Clearing OCC is the sole provider of clearing on all of our U.S. options and futures exchanges. National Securities Clearing Corporation (“NSCC”), a subsidiary of the Depository Trust and Clearing Corporation (“DTC”), is the sole provider of clearing on our U.S. listed equity exchanges. The Canadian Depository for Securities (“CDS”) is the sole provider of clearing on all equities transactions occurring on MATCHNow. With respect to Australian equities and derivatives, Cboe Australia delivers matched trades of its customers to ASX Clear Pty Ltd and ASX Settlement Pty Ltd. ASX Clear Pty Ltd acts as a central counterparty on all transactions occurring on Cboe Australia. The Japan Securities Clearing Corporation 16 Table of Contents (“JSCC”) is the sole provider of clearing on all equities transactions occurring on Cboe Japan’s Chi-Alpha, Chi-Select,Chi-Match and Kai-X. BofA Securities, Inc. (“BOA”) is the sole provider of clearing on all equities transactions occurring on BIDS Trading. Cboe Europe Equities and Derivatives relies on LCH Limited and LCH SA (“LCH”), EuroCCP, which is described above, and SIX x-clear Ltd (“SIX x-clear”) to clear trades in European listed equity securities and derivatives as part of an interoperable clearing model. Cboe Trading is a routing broker-dealer used by our four U.S. equities exchanges and our four U.S. options exchanges, including the electronic platform portion of Cboe Options. Cboe Trading’s clearings firms are Wedbush Securities, Inc. (“Wedbush”) and Morgan Stanley & Co. LLC (“Morgan Stanley”). Regulatory Environment and Compliance Various aspects of our business are subject to regulation by the SEC, CFTC, FINRA, IIROC, the Ontario Securities Commission (the “OSC”), the Australian Securities & Investments Commission (“ASIC”), JFSA, JSDA, ESMA, FCA, the Central Bank of the Netherlands (“DNB”), AFM, and other international regulatory authorities where our exchanges or EuroCCP may be authorized to act as foreign exchanges or provide clearing services, and market participants may be subject to regulation by the SEC, CFTC, FINRA, National Futures Association (“NFA”), FCA, Board of Governors of the Federal Reserve, U.S. Department of the Treasury and/or foreign regulators. The following is a discussion of the more significant areas of regulation of us by the SEC, the CFTC, and certain European regulators. Recent Developments Laws and regulations regarding our business are frequently modified or changed to address perceived problems, new products, or competition or at the request of market participants. The following is a brief discussion of recent regulatory developments that may significantly impact our business. United States Consolidated Data Plan Order On May 6, 2020, the SEC issued an order (the “Consolidated Data Plan Order”) that would require U.S. equities exchanges and FINRA to develop and file a new consolidated data plan (the “Plan”) that would replace the three current U.S. equities tape data plans and require certain governance provisions, such as changes to the voting structure. Pursuant to the Consolidated Data Plan Order, we and the other U.S. equities exchanges and FINRA were required to file the proposed Plan for public comment before the SEC takes any definitive action on such new plan. The proposed Plan was filed on August 11, 2020 and on August 6, 2021 the SEC approved such Plan. The Plan was subsequently challenged by exchanges and the courts granted a stay of the Plan. Until a decision is made by the courts, the current data plans will continue to govern. Our equities exchanges, BZX, BYX, EDGX, and EDGA, may require additional resources to comply with or challenge the Consolidated Data Plan Order and the Plan may have a material impact on our business, financial condition and operating results if, for example, there is a negative impact on the applicable market data revenues that we receive that are generated from such new plan. See “Risk Factors” and “Legal Proceedings” for more information. Financial Transaction Taxes A number of federal, state and local jurisdictions in the U.S. and EU Member States have considered a financial transaction tax, but many details remain to be discussed and agreed, including how to assess the tax.Additionally, legislation has been proposed from time to time on a federal level that would introduce in the U.S. mark-to-market tax treatment for all derivatives contracts and require gains and losses be taxed at ordinary income tax rates. Implementation of such taxes could result in a reduction in volumes and liquidity, which would have a negative impact on our operations. See “Risk Factors” for more information. Market Data Infrastructure Rule On December 9, 2020, the SEC issued a Market Data Infrastructure Final Rule, which makes significant additions to the content available on the Securities Information Processors (“SIPs”) and replaces the exclusive processors with a competing consolidator model. The implementation of the new rules could cause Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or to challenge the new rules and they may have a 17 Table of Contents material impact on our business, financial condition and operating results if, for example, there are lower SIP plan revenues or we must reduce the fees we charge for market data. See “Risk Factors” and “Legal Proceedings” for more information. Europe Capital Markets Union The European Council (“E.C.”) has highlighted one of its top priorities as being the establishment of a fully functioning, well-regulated Capital Markets Union (“CMU”). An Action Plan of concrete steps was set out in September 2015, and an update of the list of initiatives was published in September 2016. In November 2019, the E.C. set up a High Level Forum on CMU, resulting in a final report published in June 2020. On September 24, 2020, the E.C. published a new CMU Action Plan, and on November 25, 2021, published a set of legislative proposals in furtherance of the CMU, including proposals to amend the Markets in Financial Instruments Regulation (“MiFIR”) described in the EU Transparency Rules section below. This therefore remains an ongoing project for the E.C., which may result in additional regulation or legislation. In November 2021 the EU Commission published an update regarding progress against the CMU Action Plan alongside a number of new legislative proposals designed to contribute to the objectives of CMU. These included proposals to: ● Create a European Single Access Point (“ESAP”) which will be a common source of public, free information about EU companies and investment products, regardless of where in the EU they are located or originated. ● Amendments to attractthe ELTIF framework to promote long-term investments through European Long-Term Investment Funds (“ELTIFs”). ● Making funding more diversified for companies by reviewing the Alternative Investment Fund Managers Directive (“AIFMD”). ● Enhancing market transparency by reviewing the Markets in Financial Instruments Regulation (“MiFIR”). OTC Derivatives, Central Counterparties and Trade Repositories Regulation (EU) No 648/2012 of the European Parliament and of the Council of July 4, 2012 on OTC derivatives, central counterparties and trade repositories (the “European Market Infrastructure Regulation” or “EMIR”) sets out rules relating to over-the-counter (“OTC”) derivatives markets, central counterparties and trade repositories. The rules introduce a reporting obligation for OTC derivatives markets, a clearing obligation for eligible OTC derivatives markets, measures to reduce counterparty credit and operational risk for bilateral OTC derivatives markets, CCPs, and trade repositories, and rules on the establishment of interoperability between CCPs. EMIR was enhanced and amended in June 2019. In addition, regulation governing the authorization and supervision of Central Securities Depositories (“CSDR”) was approved in September 2014, with the publication of most “Level 2” Regulatory Technical Standards in March 2017, with implementation in March 2019. CSDR may result in the introduction of mandatory buy-ins for OTC business in 2022 although recent communications from ESMA and the EU Commission have indicated that the intended implementation date of February 1, 2022 will be postponed pending a further review of those proposals by the EU Commission during 2022. Rules in relation to the calculation and collection of cash penalties are expected to come in to force in February 2022. The Central Counterparty Recovery and Resolution Regulation (“R&R Regulation”) was published in the Official Journal of the EU on January 22, 2021, which may, among other things, increase the amount of prefunded capital EuroCCP is required to maintain. This additional prefunded capital may be required to be drawn before any recovery measures can be taken by the CCP. On July 12, 2021, and November 18, 2021, ESMA proposed a set of level 2 and level 3 guidance pursuant to the R&R Regulation. As European authorities finalize and potentially adopt level 2 and 3 guidance, the final R&R Regulation may have a material adverse effect on our clearing business, financial condition and operating results. EU Transparency Rules On November 11, 2021, the European Council (“E.C.”) published its proposal for a review of EU market structure legislation, including proposed amendments to Markets in Financial Instruments Regulation (“MiFiR”) and Directive 2014/65/EU on markets in financial instruments (“MiFID II”). The proposal includes, among other provisions, provision for 18 Table of Contents a consolidated tape for the EU and changes to the transparency regime for equities. These proposals are expected to be implemented in late 2023 or early 2024. In addition, the European Securities and Markets Authority (“ESMA”) also published its proposal for a review of EU transparency rules. The proposal includes, among other provisions, provision for increased pre-trade transparency for periodic auctions and post-trade flagging. These proposals may be implemented in the second half of 2022 although they may also be incorporated into the wider MiFiR review. As proposed, these proposals may have a material adverse effect on our business, financial condition and operating results. See “Risk Factors” for more information. Compliance U.S. Securities Industry Federal securities laws have established a two-tiered system for the regulation of securities exchanges and market participants. The first tier consists of the SEC, which has primary responsibility for enforcing federal securities laws. The second tier consists of self-regulatory organizations (“SROs”), which are non-governmental entities that must register with and are regulated by the SEC. The Exchanges are SROs, each registered under Section 6 of the Exchange Act of 1934, as amended (“Exchange Act”) as a “national securities exchange,” and are subject to oversight by the SEC. SROs are an essential component of the regulatory scheme of the Exchange Act for providing fair and orderly markets and protecting investors. To be registered as a national securities exchange, an exchange must successfully undergo an application and review process with the SEC prior to beginning operations. Among other things, the SEC must determine that the SRO has the ability to comply with the Exchange Act and to enforce compliance by its members and persons associated with its members with the provisions of the Exchange Act, the rules and regulations thereunder and the rules of the exchange. In general, an exchange SRO is responsible for operating its trading platforms consistent with its rules, and regulating its members through the adoption and enforcement of rules governing the business conduct of its members. The rules of the exchange must also assure fair representation of its members in the selection of its directors and administration of its affairs and, among other things, provide that one or more directors be representative of issuers or investors and not be associated with a member of the exchange or with a broker or dealer. Additionally, the rules of the exchange must be adequate to ensure fair dealing and to protect investors and may not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Exchange Act. As registered national securities exchanges, virtually all facets of our Exchange operations are subject to the SEC’s oversight, as prescribed by the Exchange Act. The Exchange Act and the rules thereunder impose on us many regulatory and operational responsibilities, including record keeping and the day-to-day responsibilities for market operations and broker-dealer oversight. Furthermore, as SROs, the Exchanges are potentially subject to regulatory or legal action by the SEC or other interested parties. The SEC also has broad enforcement powers to censure, fine, issue cease-and-desist orders, prohibit us from engaging in some of our businesses, suspend or revoke our designation as a registered securities exchange or remove or censure any of our officers or directors who violate applicable laws or regulations. For example, in 2013, Cboe Options and C2 and, in 2015, EDGX and EDGA, entered into consent orders with the SEC, under which they were censured, ordered to cease and desist from violating certain sections of the Exchange Act, paid fines and agreed to complete certain undertakings. We have certified to the completion of these undertakings and are no longer required to certify. As part of its regulatory oversight, the SEC conducts periodic reviews and inspections of exchanges, and the Exchanges have been subject to such routine reviews and inspections. To the extent such reviews and inspections result in regulatory or other changes, we may be required to modify the manner in which we conduct our business, which may adversely affect our business. We collect certain fees to cover Section 31 fees charged to the Exchanges by the SEC and certain fees derived from our regulatory function and fines in connection with our disciplinary proceedings. The Exchanges are responsible for the ultimate payment of Section 31 fess to the SEC. Additionally, under the rules of each of our exchanges, as required by the SEC, any revenue derived from the regulatory fees and fines cannot be used for non-regulatory purposes. Section 19 of the Exchange Act also provides that we must submit to the SEC proposed changes to any of the Exchanges’ rules, including revisions of their certificates of incorporation, bylaws, or other governing documents of the 19 Table of Contents SROs or their parent companies. The SEC will typically publish the proposal for public comment, following which the SEC may approve or disapprove the proposal, as it deems appropriate. Certain categories of rule changes, like fee changes, can be effective on filing, but the SEC retains the ability to suspend or reject such filings within a prescribed period of time. Canadian Securities Industry MATCHNow is subject to comprehensive regulation and oversight by its primary provincial securities regulatory authority, the OSC, and by IIROC. The regulations applicable to MATCHNow cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability. Australian Securities Industry Cboe Australia is subject to comprehensive regulation and oversight by the ASIC. The regulations applicable to Cboe Australia cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability. Japanese Securities Industry Cboe Japan is subject to comprehensive regulation and oversight by the JFSA and the JSDA. The regulations applicable to Cboe Japan cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability. Futures and Swaps Industry-CFE and Cboe SEF The operations of each of CFE and Cboe SEF are subject to regulation by the CFTC under the Commodity Exchange Act. The Commodity Exchange Act generally requires that futures trading in the United States be conducted on a designated contract market and, in some cases, requires swaps trading to be conducted on swap execution facility (“SEF”) or designated contract market (“DCM”). The Commodity Exchange Act and CFTC regulations establish criteria for an exchange to be designated as a contract market on which futures and futures options contracts may be traded, and for a trading platform to be designated as a swap execution facility on which certain swaps may be traded. Designation as a contract market or swap execution facility for the trading of specified futures or swaps contracts is non-exclusive. This means that the CFTC may permit additional exchanges or trading platforms to be contract markets or swap execution facilities for trading the same or similar contracts. CFE is a designated contract market, and Cboe SEF is a swap execution facility, each of which is subject to the oversight of the CFTC and to a variety of ongoing regulatory and reporting responsibilities under the Commodity Exchange Act. As a designated contract market, CFE is required to comply with the applicable core principles and regulations under the Commodity Exchange Act, as is Cboe SEF as a swap execution facility. Each of CFE and Cboe SEF has surveillance and regulatory operations and procedures to monitor and enforce compliance by trading privilege holders with CFE rules, and by participants with Cboe SEF rules, as applicable. If CFE or Cboe SEF fails to comply with applicable laws, rules or regulations, it may be subject to censure, fines, cease-and-desist orders, suspension of its business, removal of personnel or other sanctions, including revocation of CFE’s designation as a contract market or Cboe SEF’s designation as a swap execution facility. Europe Cboe Europe is located in London and is subject to regulation in the UK and to certain European regulations. The current UK regulatory system was established by the Financial Services Act 2012 (“FSA12”), which amended the Financial Services and Markets Act 2000. The legislation replaced the previous financial services regulator, the Financial Services Authority, with three new bodies: The Financial Policy Committee (“FPC”), The Prudential Regulation Authority, and the FCA. Financial conduct of markets, including activity on, and the operation of, markets is regulated by the FCA, which is an independent non-governmental body, given statutory powers by the FSA12. The FCA has three statutory objectives: to secure an appropriate degree of protection for consumers; to protect and enhance the integrity of the UK financial system; and to promote effective competition in the interests of consumers in the markets for financial services. The FCA is accountable to Her Majesty’s Treasury Ministers and, through them, to Parliament. 20 Table of Contents EuroCCP and Cboe NL are located in Amsterdam and subject to Dutch law and regulation. The current Dutch regulatory system was established by the Act on Financial Supervision. Financial conduct of markets, including activity on, and the operation of, markets is regulated by the AFM. Financial conduct of CCPs, including clearing activity is regulated by the AFM and DNB. The AFM is an independent non-governmental body, given statutory powers by the Act on Financial Supervision. The AFM has three strategic objectives: to promote the fair and conscientious provision of financial services, to promote the fair and efficient operation of the capital markets and to contribute to the stability of the financial system. The AFM is accountable to the Minister of Finance. The DNB is the Dutch central bank, financial sector supervisor and resolution authority. The DNB is committed to a stable financial system: stable prices, solid financial institutions and properly functioning payment transfers. Much of the UK and Dutch financial services regulation originates from the EU. Such regulation includes organizational requirements, capital resources requirements and the specific requirements for RMs and MTFs and are applicable to both Cboe Europe and Cboe NL. MiFID II and MiFIR set out requirements for RMs and MTFs with respect to the establishment of transparent and non-discretionary rules and procedures governing access and for fair and orderly trading and the efficient execution of orders, as well as to facilitate the efficient settlement of transactions conducted on RMs and MTFs and monitoring compliance with the rules. EMIR governs the CCPs operating in the EU and requires them to meet common risk management, governance and capital adequacy standards. The regulatory functions required of Cboe Europe Equities and Derivatives, including EuroCCP, by MiFID II, MiFIR, EMIR and other relevant legislation and regulations are performed by in-house staff. Cboe Europe Equities and Derivatives utilizes the same state-of-the-art, real-time surveillance system is used on the U.S. to monitor trading and market activities on BZX, BYX, EDGA, and EDGX. EuroCCP utilizes proprietary risk management software to monitor settlement and funding flows. Global FX While the global institutional spot FX market remains largely unregulated, the enactment of the Dodd Frank Act and its related regulations in the United States and the ongoing implementation of MiFID II and MiFIR in Europe have impacted the regulatory landscape for currency derivative products. For example, certain standardized currency derivative products are required to trade on an organized trading venue such as a SEF or DCM in the United States or on an MTF or organized trading facility in Europe. Moreover, even in the largely unregulated spot FX market, this movement towards additional trading standards and norms is highlighted by the publication of the FX Global Code in 2017 by the Global Foreign Exchange Committee, reflecting principles of good conduct for the wholesale FX market, and whose publication may lead to additional oversight in the global FX market. Cboe FX issued a Statement of Commitment declaring its commitment to conduct its FX market activities in a manner consistent with the principles of the FX Global Code. Following the publication of the FX Global Code regulators are taking a new look at the spot FX market, and any decision to impose new regulations may affect our spot FX business line. Broker-Dealer Cboe Trading and BIDS Trading are registered broker-dealers regulated by the SEC, FINRA, other SROs of which they are members and various state securities regulators. Cboe Trading currently operates as a routing broker-dealer for sending orders from the Exchanges to other venues for execution, including routing orders among the Exchanges. Cboe Trading is considered a facility of each of the Exchanges and is subject to the rules of the Exchanges. The Exchanges are responsible for enforcing Cboe Trading’s compliance with their rules, including to ensure Cboe Trading is not given preferential treatment. BIDS Trading currently operates an ATS, which is designed to bring counterparties together to anonymously trade large blocks of U.S. equities. BIDS Trading is not a member of any of the U.S. national securities exchanges and is not subject to exchange rules. Cboe Trading and BIDS Trading are subject to SEC and SRO rules, as applicable, and, as registered broker-dealers, regulations concerning all aspects of their businesses, including trading practices, order handling, best execution, anti-money laundering, handling of material non-public information, safeguarding data, reporting, capital adequacy, record retention, market access and the conduct of their officers, employees and other associated persons. The SEC, SROs and state securities commissions may conduct proceedings which can result in injunctions or other sanctions, censures, fines, the issuance of cease and desist orders or the suspension or expulsion of a broker-dealer, its officers or employees. The SEC and FINRA impose certain minimum capital requirement rules that require notification when a broker-dealer’s net capital falls below certain predefined criteria, dictate the ratio of debt to equity in the regulatory capital composition of a broker-dealer, constrain the ability of a broker-dealer to expand its business under certain circumstances and impose certain requirements that may have the effect of prohibiting a broker-dealer from distributing or withdrawing capital. 21 Table of Contents In addition, the ATS operated by BIDS Trading is not a registered national securities exchange or a facility thereof, as such, Cboe intends to maintain the BIDS ATS as an independently managed and operated trading venue, separate from and not integrated with the Exchanges. The Chief Executive Officer of BIDS Trading is expected to lead BIDS Trading as an independent business within Cboe, reporting into an independent committee of the board of Cboe Global Markets. Further, Cboe Trading will not route orders to BIDS Trading on behalf of the Exchanges. Cboe Global Markets Certain aspects of Cboe Global Markets are also subject to SEC, FCA and AFM oversight, including certain ownership and voting restrictions on its stockholders. The focus of the SEC’s regulation of Cboe Global Markets is to assure fair representation of members in the selection of the directors of the Exchanges, public participation in the governance of the Exchanges and that the Exchanges can satisfy their regulatory responsibilities under the Exchange Act. Furthermore, the SEC requires that Cboe Global Markets give due regard to the preservation of the independence of the self-regulatory function of the Exchanges and to Cboe Global Markets’ obligations to investors and the general public. The SEC also requires that Cboe Global Markets not take any actions that would interfere with the effectuation of any decisions by the Board of Directors of any of the Exchanges relating to its regulatory functions or the structure of the market that it regulates or that would interfere with the ability of such Exchange to carry out its responsibilities under the Exchange Act. To the extent that Cboe Global Markets’ business activities involve or relate to the Exchanges, the officers and directors of Cboe Global Markets may be deemed to be officers and directors of the exchanges for purposes of and subject to oversight under the federal securities laws. Accordingly, the SEC may exercise direct supervision and disciplinary authority over certain Cboe Global Markets’ activities and those activities may be subject to SEC approval and, in some cases, public notice and comment. In addition, Cboe Global Markets indirectly holds all of the issued share capital and voting rights in Cboe Europe and its wholly owned subsidiaries, Cboe Chi-X Europe and Cboe NL. As a result, we and any person who holds, or has voting power with respect to, 10% or more of the outstanding shares of Cboe Global Markets common stock may be subject to certain regulatory requirements under UK and Dutch law. U.S. Regulatory Responsibilities Our U.S.-based exchanges are responsible for assessing the compliance of their TPHs or members, including Cboe Trading, with the respective exchange’s rules and the applicable rules of the SEC and/or CFTC. The main activities that the exchanges, as applicable, are required to monitor for the purpose of compliance with these rules include: ● surveillance designed to detect violations of exchange trading rules; ● surveillance designed to detect violations of SEC and/or CFTC rules; ● investigation of matters involving potential rule violations; ● the investigation of complaints about possible rule violations brought by customers, TPHs, members or other SROs; and retain qualified compliance, risk and audit management personnel. These systems and procedures may not be fully effective. We face ● the riskexamination of intervention by regulatory authorities, including extensive examination and surveillance activity. In the case of actualTPHs or alleged non-members for compliance with applicable laws or regulations, we could be subjectrules such as those related to investigationsnet capital, books and judicial or administrative proceedings that may result in penalties, settlements or civil lawsuits, including by customers, for damages, which may be substantial. In the past, the SEC has brought actions against exchange operators, including us, for failing to fulfill their obligations to have an effective regulatory system. Any failure to comply with applicable laws and rules could adversely affect our business, reputation, financial condition and operating results and, in extreme cases, our ability to conduct our business or portions thereof. As the parent company for SROs, we are responsible for maintaining exchanges that comply with securities and futures laws, SEC, FCA, AFM and CFTC regulations and the rules of the respective exchanges. We have methods to identify, monitor and manage our risks. Management of legal and regulatory risk requires policies and procedures to properly monitor and manage risk. If our policies, procedures, and compliance systems are not effective or we are not successful in monitoring or evaluating the risks to which we are or may be exposed, our business, reputation, financial condition and operating results could be materially adversely affected. We cannot provide assurance that our policies and procedures will always be effective, or that our management, compliance department, risk department and related enterprise risk management program and internal audit department would be able to identify any such ineffectiveness. If these departments or the enterprise risk program, and related policies and procedures are not effective, we may be subject to monetary or other penalties by our regulators, and our insurance policies may not provide adequate coverage. Financial or other problems experienced by third parties could have an adverse effect on our business. We are exposed to credit risk from third parties, including customers, clearing agents and counterparties. For example, we are exposed to credit risk for transaction fees we bill to customers on a monthly basis in arrears. Our customersrecords, market access and other third parties may default on their obligations to us due to a lack of liquidity, operational failure, bankruptcy or other reasons. In addition, with respect to orders Cboe Trading routes to other markets for execution on behalf of our customers, Cboe Trading is exposed to counterparty credit risk in the case of failure to perform on the part of our routing and clearing firms who are involved in processing equities and options transactions on our behalf, as well as failure on the part of such brokers to pass back any transactional rebates. Wedbush Securities Inc. (“Wedbush”), and Morgan Stanley & Co. LLC (“Morgan Stanley”) guarantee equity trades until one day after the trade date, after which time NSCC provides a guarantee. Thus, Cboe Trading is potentially exposed to credit risk to the counterparty to an equity trade routed to another market center between the trade date and one day after the trade date in the event that Wedbush or Morgan Stanley fails to perform. With respect to U.S. listed equity options and futures, we deliver matched trades of our customers to the OCC, which acts as a central counterparty on all transactions occurring on Cboe Options, C2, BZX, EDGX, and CFE and, as such, guarantees clearance and settlement of all of our matched options and futures trades. With respect to U.S. equities, Cboe Trading has counterparty credit risk exposure to Wedbush and Morgan Stanley related to clearing until the day following the trade date. Cboe Trading uses Wedbush to clear trades routed through affiliates of Credit Suisse Securities (USA) LLC as well as for trades routed directly to other exchanges and optionally dark pools. Morgan Stanley clears trades routed through the Morgan Stanley routing brokers and also clears executions routed to most dark pools. Cboe Trading maintains counterparty credit risk exposure from routing brokers with respect to rebates earned until completion of the routing brokers next invoice cycle following the execution. With respect to U.S. listed equity and exchange traded product options, Cboe Trading is subject to counterparty credit risk exposure with respect to rebates earned from routing brokers until completion of the routing brokers’ next invoice cycle has completed for an execution. 38 Table of Contents Our exposure to credit risk may be further impacted by volatile securities markets that may affect the ability of our customers and other third parties to satisfy their contractual obligations to us. Moreover, we may not be successful in managing our credit risk through reporting and control procedures or by maintaining credit standards. Any losses arising from such defaults or other credit losses could adversely affect our financial condition and operating results. While neither Cboe FX nor Cboe SEF has direct counterparty risk, Cboe FX or Cboe SEF may suffer a decrease in transaction volume if a bank or prime broker experiences an event that causes other prime brokers to decrease or revoke the credit available to the prime broker experiencing the event. Therefore, Cboe FX and Cboe SEF may have risk that ismatters related to the creditTPHs’ or members’ exchange business functions. In order to ensure market integrity, we regulate and monitor our TPHs’ and members’ trading activities by using both our employees and third parties under regulatory services agreements (“RSAs”). See “Regulatory Agreements” below. Providing effective regulation is important for attracting and retaining the confidence and participation of market-makers, broker-dealers and institutional and retail investors. We expend considerable time, financial resources and effort to ensure that the exchanges’ rules and regulations conform to regulatory best practices within the securities and futures exchange industries and within the regulatory regime overseen by the SEC and CFTC, our primary regulators. In order to support our efforts and those of our market participants to comply with applicable law and our exchange rules, we developed a regulatory program to monitor market activity on our exchanges. All of our Exchanges and CFE are participants in the Intermarket Surveillance Group (“ISG”). ISG is an international information-sharing cooperative governed by a written agreement that provides for a comprehensive surveillance sharing arrangement. In addition to the agreement for confidential information sharing, the ISG provides a framework for the coordination of regulatory efforts among exchanges trading securities, commodity futures and related products to address potential intermarket manipulations and trading abuses. 22 Table of Contents As part of the regulatory program, each of our Exchanges and CFE have rules pertaining to their respective disciplinary processes. U.S. Regulatory Agreements The Exchanges and CFE have entered into agreements under which third parties have agreed to perform regulatory functions on behalf of our markets (e.g., RSAs). As discussed below, in addition, in certain other instances for our Exchanges, a third party has been allocated the regulatory responsibility under Rule 17d-1 or Rule 17d-2 under the Exchange Act, while in others, we retain the regulatory responsibility for the activities. Regulatory Services Agreement with FINRA The Exchanges have entered into agreements with FINRA under which FINRA has agreed to provide regulatory services to the Exchanges. Under these agreements, FINRA performs certain regulatory functions on behalf of the Exchanges and, to avoid any potential conflicts of interest concerning the regulation and oversight of Cboe Trading, certain regulatory services specific to Cboe Trading. The Exchanges remain responsible for the regulation of their TPHs, members and marketplaces, and retain the authority for bringing disciplinary actions against their TPHs and members, although FINRA performs certain disciplinary-related functions on behalf of the Exchanges. Over the course of 2019 through 2021, certain regulatory and disciplinary-related functions that FINRA had performed on behalf of the Exchanges have been moved back in-house from FINRA. Regulatory Services Agreements with NFA and OCC Through December 31, 2020, the NFA performed regulatory functions on behalf of CFE pursuant to an RSA with CFE. The RSA has been terminated and, starting January 1, 2021, these regulatory functions were moved in-house from the NFA. In addition, OCC has also performed and continues to perform certain regulatory functions on behalf of CFE pursuant to an RSA with CFE. CFE also performs other regulatory and disciplinary-related functions in-house. Whether performed under an RSA or in-house, CFE retains overall responsibility for the regulation of its marketplace and for bringing disciplinary actions. CFE is also a party to cooperative and regulatory information sharing agreements with other SROs and is a member of the ISG, described above. Rule 17d-1 Designations and Rule 17d-2 Agreements Section 17(d) of the Exchange Act and the related Exchange Act rules permit SROs to allocate certain regulatory responsibilities to avoid duplicative oversight and regulation. Under Exchange Act Rule 17d-1, the SEC designates one SRO to be the designated examining authority (“DEA”) for each broker-dealer that is a member of more than one SRO. The DEA is responsible for the regulatory oversight of applicable financial responsibility rules pertaining to that broker-dealer. Cboe Options is the DEA for several of its TPHs. Cboe Trading’s assigned DEA is FINRA. Exchange Act Rule 17d-2 permits SROs to enter into agreements, commonly called Rule 17d-2 agreements, which are approved by the SEC and concern the allocation of regulatory responsibility for rules applicable to TPHs and members that those SROs have in common. The Exchanges have entered into certain bi-lateral Rule 17d-2 agreements under which FINRA is allocated responsibility for enforcing certain federal securities laws and certain exchange rules that are common with FINRA rules. The Exchanges have entered into certain other multi-party Rule 17d-2 agreements that allocate responsibility among the participating SROs, which may include the Exchanges, for oversight of their allocated common members compliance with certain rules governing, among other items, options related sales practices, options related market surveillance, insider trading, NMS and consolidated audit trail NMS plan (“CAT”) compliance. National Market System Plans We are member participants of several NMS plans including, but not limited to, the following: Cboe Options, C2, BZX, and EDGX are member exchanges in OPRA, which is the designated securities information processor for market information that is generated through the trading of exchange-listed securities options in the United States, and it disseminates certain core trading information, such as last sale reports and quotations. Cboe Options, BZX, BYX, EDGA, and EDGX also participate in the CTA/CQ and the UTP Plans, which perform analogous services for the U.S. equities market. Securities Information Automation Corporation (“SIAC”) acts as the “processor” for OPRA and the CTA/QC Plans. Nasdaq Stock Market, LLC acts as the processor for the Nasdaq Unlisted Trading Privileges Plan. Also, see “Regulatory Environment and Compliance - Recent Developments - United States - Consolidated Data Plan Order”, “Risk Factors” and “Legal Proceedings” for more information regarding the Consolidated Data Plan Order and the Plan. 23 Table of Contents Cboe Options, C2, BZX, and EDGX are also parties to the Options Order Protection and Locked/Crossed Market Plan, which is designed to prohibit trade-throughs and avoid locked/crossed markets. Cboe Options, C2, BZX, and EDGX are also parties to the Options Listing Procedures Plan, which sets forth the procedures that the options exchanges must follow to list new options. Cboe Options, BZX, BYX, EDGA, and EDGX are also parties to the NMS plan for the selection and reservation of securities symbols. Under the Options Regulatory Surveillance Authority Plan (“ORSA Plan”), U.S. securities options exchanges are permitted to act jointly in the administration, operation and maintenance of a regulatory system for the surveillance, investigation and detection of the unlawful use of undisclosed, material information in trading in one or more of their markets. The ORSA Plan is intended to enhance the effectiveness and efficiency with which the exchanges regulate their respective markets and to avoid duplication of certain regulatory efforts. FINRA operates the ORSA Plan facility for options insider trading. The CAT involves the creation of a comprehensive audit trail that strives to enhance regulators’ ability to monitor trading activity in the U.S. securities markets through a phased implementation. Upon final implementation of the provisions of the CAT, data will be required to be reported to a central repository the following day by each SRO (a “Plan Participant”) and broker-dealer (an “Industry Member”). On November 15, 2016, the SEC approved the CAT. The first of various phases of CAT were originally required to begin in November 2017; however, there have been some delays. In 2017, Thesys CAT LLC (“Thesys”), a subsidiary of Thesys Technologies, LLC, was selected as the plan processor with the responsibility to build and operate the CAT. The first phase of CAT ultimately went live in November 2018, at which time we and other SROs/Plan Participants began initial reporting to the CAT. In 2019, Thesys was replaced by a new plan processor, FINRA CAT, LLC, a subsidiary of FINRA. The second phase for Industry Member order and trade file submissions is now live and began in June 2020 (for equities), June/July 2020 (for options), and additional sub-phases related to order and trade file submissions were implemented through December 2021. The final implementation sub-phase, related to broker-dealer customer and account information submissions by Industry Members, is now scheduled to go live in July 2022 (or by a subsequent date in the event the current deadline is extended). While the funding of the CAT is ultimately expected to be provided by both the SROs/Plan Participants (which includes our U.S.-based securities exchanges) and Industry Members, until fee filings associated with the funding model are effective with or approved by the SEC, the funding to date has solely been provided by the SROs/Plan Participants. The funding by the SROs/Plan Participants has been done in exchange for promissory notes expected to be repaid once such Industry Member fees are collected. Until those fees are collected, the SROs/Plan Participants may continue to incur additional significant costs, including as a result of replacing the plan processor, or result in the uncollectibility of promissory notes related to the funding of the implementation and operation of the CAT. See Note 8 (“Credit Losses”) and Note 9 (“Other Assets, Net”) for further information. In addition, on February 14, 2021, Consolidated Audit Trail, LLC, formed by SRO Plan Participants to implement the CAT requirements, filed motions to stay all or portions of two exemptive orders the SEC issued on December 16, 2020 related to the implementation of the CAT. On February 16, 2021, Consolidated Audit Trail, LLC also petitioned the U.S. Court of Appeals for the District of Columbia Circuit (“D.C. Circuit”) for judicial review of the two exemptive orders, asserting that the orders are unlawful. On April 7, 2021, the D.C. Circuit ordered the case to remain in abeyance, directed the filing of status reports every 60 days and ordered the parties “to file motions to govern future proceedings within 30 days after the discussions between the parties and the agency proceedings are completed.” Intellectual Property We own or have rights to a number of intellectual property assets, including trademarks, service marks, domain names, trade names, copyrights, trade secrets and patents. While the majority of our intellectual property is protected under U.S. law, we have many intellectual property assets protected by laws in Europe, Asia and other parts of the world. We license some intellectual property assets to other entities. We attempt to protect our intellectual property rights, while respecting the legitimate intellectual property rights of others. Human Capital Management Cboe has a robust human capital management program in place focused on equal opportunities including diversity, equity and inclusion (“DEI”), performance and career development, health and well-being, comprehensive benefits, training, talent acquisition, and succession planning. Additional information on our approach to human capital and ESG issues can be found in the Cboe Global Markets, Inc. Environmental, Social and Governance Report located in the Corporate Social Responsibility section of our website at https://markets.cboe.com/about/corporate-social-responsibility, which does not form a part of this Form 10-K. 24 Table of Contents Equal Opportunity, Diversity, and Pay Equity Cboe believes in a culture of diversity and inclusion that promotes creativity, collaboration and innovation, which is critical to the success of our business and defining the markets of tomorrow.

Our commitment and responsibility in this regard starts at the top, with leadership and support from the full Cboe Board of Directors and executive team. One of the most compelling examples of our pledge to equality, diversity and inclusion throughout our Company is the completion of our first pay equity study in 2019. In 2020, we finalized the implementation of the findings of our inaugural study. To maintain and strengthen our efforts in this area, we also review the critical touchpoints across the employee journey with Cboe to keep a level playing field, from the talent selection, promotion, leadership development and succession planning processes and make adjustments, as necessary, to ensure opportunity parity across the Company. Our goal is to ensure that equal pay and equal opportunity for all that results in a collaborative, high performing organization bringing new innovations to market and providing superior service to our customers. The Cboe Women’s Initiative works toward its mission: to increase representation, strengthen voices, and build a culture of opportunity and advancement for the women of Cboe. The Women’s Initiative is led by an associate board and engages women throughout the Company on a variety of programs. More specifically, the Women’s Initiative is comprised of three committees that target areas where its membership strives to promote change, such as networking events, building a formal mentorship program and an advocacy group aimed at gathering input on topics of importance for its membership. This outreach helps shape the planning and focus for the Initiative. Networking events include the “Trailblazers” events where senior women share their success stories through personal accounts of career growth and impact and speakers on Male Allyship in the workplace. In its first year, the mentorship program paired over 45 mentors with mentees across the Company. We are also proud to share that Cboe recently formed an employee Diversity Leadership Council in 2020 focused on unlocking the potential of a variety of perspectives, capabilities and cultural experiences. We believe in a culture of diversity and inclusion that promotes creativity, collaboration and innovation, which is critical to the success of our business and defining the markets of tomorrow. To reinforce this belief, this council is a collective voice on how Cboe strives to create a diverse workforce that reflects the world in which we operate. Further, they are charged with oversight on how we build an inclusive culture where every employee feels welcome, safe and empowered. In 2021, we also created a new DEI leadership position within our human resources organization to be accountable for helping to establish the strategy and execution of our DEI approach to attract develop and retain top diverse talent while fostering a community of belonging and inclusion. To reinforce our commitment to organizational wide education and commitment to diversity and inclusion we provided a full-day Unconscious Bias training through third-party experts for all managers around the globe in 2020 with the commitment to continue the rollout of this program for all employees. In addition, in 2021, we launched Cboe Empowers and Cboe’s Veterans Initiative. Cboe Empowers is a community engagement program that provides mentorship, scholarship and guidance to under-resourced students throughout their educational journey through access to Cboe's associates, resources, work environment and other learning and experience opportunities. Initially launched in Chicago, the vision for Cboe Empowers is to support students through all stages of education from elementary or primary school to career by providing mentorship, learning and experience opportunities, professional development and scholarships to students within the Chicago Public School system and graduates pursuing higher education. Cboe Empowers expects to supplement its own programs by collaborating with local partners, including the Greenwood Project and Working in the Schools, to help create maximum impact for its participants. The Cboe Veterans Initiative is an Associate Resource Group that operates based on four main pillars: recruiting, mentorship, service, and networking. The vision for the Cboe Veterans Initiative is to actively seek Veteran talent, provide mentorship to veterans within and outside of the Company, commit to giving back to the Veteran community through financial and non-monetary support, and encourage outreach to Cboe Veterans. 25 Table of Contents Performance and Career Development Cboe expects employees to perform their duties to the best of their ability and to develop their competencies for career growth. We recognize the need to provide ongoing, timely, and constructive performance feedback. Cboe has designed a Performance Management Program that drives the professional development of our employees while also providing fair and equitable rewards and recognition. The principles of performance management include: ● align performance expectations with strategy and goals of the banksbusiness, ● ongoing open dialogue regarding performance and prime brokers that trade spot FX on the Cboe FX platform, or non-deliverable forward FX transactions on Cboe SEF.development, ● foster accountability for behaviors and actions which contribute to a positive culture, and ● commitment to deliver results which drive our business. To help promote employee career development, we started in 2021 and are planning to launch in 2022, SCOUT, which is an AI powered talent management tool that will help us deliver internal mobility and career development opportunities for our employees. Employee Health and Well-Being and Comprehensive Benefits Program Cboe’s vision is to support the overall wellness of employees and their families through education and activities that encourage a healthy lifestyle, resulting in improved health and productivity. Our programs and benefit plans provide a corporate atmosphere of collective well-being that incorporate strategies for physical, emotional, mental and financial wellness. Our programs focused on enhanced employee assistance programs, wellness programs and challenges, that include both mental and physical wellbeing, and webinars and classes through our retirement vendor to support the financial health of our employees. To further these efforts, we launched the CboeFit program that creates an opportunity to elevate these programs and strengthen employee engagement as we execute against our wellness vision and strategies. With the global pandemic in 2020 and 2021, there was further focus on our Employee Assistance program that was strengthened across the globe with a diverse set of mental health resources aimed at supporting our employees during a unique and challenging time. Employee Engagement and Pulse Surveys, Town Halls and an Open-Door Policy In 2021, Cboe conducted our fourth annual employee engagement survey and has implemented career, leadership, and culture focused programs in response to the survey findings. Our participation rate exceeds standard benchmarks and a significant majority of our employees would recommend Cboe as a great place to work. To further cement our commitment to Diversity and Inclusion, we added new, enhanced questions in this area. Our Diversity Leadership Council hosted a special focus group to review these specific results to listen to the voices of our diverse population, prioritize their feedback and ideas, and create commitments for actionable improvements. Our senior management team continues to hold the commitment to an open-door policy and encourages the free flow of information and communication in furtherance of active transparency. With the global pandemic, our ability to tap into the voice of our employees was critically important. We conducted regular pulse surveys to gauge sentiment in making critical decisions. Our CEO also issues weekly letters to help connect with our employees. Human Resources also provided ongoing regular resources and tips to help support the variety of challenges from the new reality of fully remote work to childcare and elder care that our employees faced throughout 2021. Cboe also continues to create an open and frank atmosphere in which any grievance, complaint, suggestion or question receives a timely response. Cboe offers a whistleblower hotline for complaints, which can be made anonymously. Additionally, employees can raise questions and suggestions to the Cboe Human Resources team either in-person or via a group email address and are either responded to individually or addressed at our Global Town Hall meetings. The objective of these town halls is to provide employees an update on Company news, share updates from major business lines, as well as provide a forum to ask questions and offer feedback. Town halls can include updates on anything from legislation that may impact our business to ESG topics. Employees are encouraged to participate in free 26 Table of Contents flow of information and communication and to offer positive and constructive feedback in furtherance of active transparency. To further reinforce our commitment to employee engagement as a result of changing work styles due to COVID-19, we began in late 2021 a future-of-work study with a third party to help determine where Cboe employees might be best suited to work from in the future, whether it is in the office, remotely, or a hybrid mix. Training and Succession Planning We believe that the development of all Cboe employees helps drive our collective success. Through skill and competency development we signal our investment in all while also enabling enhanced productivity. Through our tuition reimbursement program, our employees receive financial support in their pursuit of specialized university courses and degrees. In addition to our ongoing offering of online courses on diverse topics through our corporate university, CboeU, employees can participate in the CboeLearns hybrid program focused on virtual classroom instruction combined with work application and CboeLive, which is focused on business topics to foster organizational-wide knowledge sharing and education. Leadership is another critical element to our success at Cboe. People managers globally participated in a two-day training focused on the “4 Essential Roles of Leadership” (1. Inspire Trust; 2. Create Vision; 3. Execute Strategy; 4. Coach Potential). We expanded on our leadership training through the design and launch of a bespoke 8-week program, CboeLeads, expanding on the development of our high potential leaders further strengthening the leadership bench and accelerating readiness of this key talent pool. The senior management team participated in an additional one-day workshop focused on their roles that was also accompanied by Leadership toolkits to guide an enhanced approach to coaching and career conversations. Cboe has held several succession planning discussions with the Compensation Committee and Board of Directors to plan for the fulfillment of essential roles, such as the CEO and other senior officers. This process includes investments in advanced development planning for targeted successors to accelerate their readiness through key internal projects and assignments as well as tailored training. Diversity and inclusion are a formal part of Cboe's succession planning process as we work to identify and advance internal diverse talent and, in parallel, continually scan external talent pools for successors. Employees As of December 31, 2021, we employed 1,196 individuals, 820 of whom are based in the United States, 128 of whom are located in London, England, 9 of whom are located in Belfast, Northern Ireland, 9 of whom are located in the Greater Toronto Area, Ontario, Canada, 18 of whom are located in Calgary, Alberta, Canada, 1 of whom are located in Coquitlam, British Columbia, 86 of whom are located in Amsterdam, Netherlands, 35 of whom are located in Sydney, Australia, 17 of whom are located in Tokyo, Japan, 51 of whom are located in Manila, Philippines, 15 of whom are located in Hong Kong, 5 of whom are located in Singapore, and 2 of whom are located in Switzerland. Of these employees, 447 were involved in technology or operations and 123 were involved in direct support of trading operations. The remaining 626 employees provide business development, financial, regulation, human resources, compliance, legal, planning and research, administrative, and managerial support. We have 6 building engineers that are covered by a collective bargaining agreement, which expires on May 31, 2022, with the International Union of Operating Engineers Local 399, AFL-CIO. Management believes that we have strong relationships with our employees, and we have never experienced a work stoppage. 27 Table of Contents Information about our Executive Officers Set forth below is information regarding our executive officers: Name Age Position We may be required to assume ownership of a position in securities in connection with our order routing service, which could subject us to trading losses when our broker-dealer disposes of that position.Edward T. Tilly We offer a smart-order routing service through our broker-dealer subsidiary, Cboe Trading, which provides its customers with access to other market centers when we route their orders to those market centers for execution. In connection with this service, we may assume ownership of a position in securities. This may occur, for example, when a market center to which we have routed a customer’s order experiences systems problems and is unable to determine the status of that order. When this happens, we may make a business decision to provide a cancellation notice to our customer, relieving our customer of any liability with respect to the order. We may be informed later, however, that the order was executed at the market center to which we routed it, in which case Cboe Trading would be required to take ownership of that securities position. Our third party clearing brokers maintain error accounts on behalf of Cboe Trading into which such positions settle, and we require the respective clearing broker to trade out of those positions as expeditiously as possible, which could result in our incurring trading losses.​ We may not effectively manage our growth, which could materially harm our business, financial condition and operating results.58 We expect that our business will continue to grow, which may place a significant strain on our management, personnel, systems and resources. We must continually improve our operational, financial and regulatory systems and managerial controls and procedures, and may need to continue to expand, train and manage our workforce. We must also maintain close coordination among our technology, legal, accounting, finance, marketing, sales, regulatory and compliance functions. If we fail to manage our growth effectively, our business, financial condition and operating results could be materially harmed. Furthermore, failure to successfully expand into new asset classes or new geographies may adversely affect our growth strategy and our future profitability. Our continued growth will require increased investment by us in technology, facilities, personnel, and financial and management systems and controls. It also will require expansion of our procedures for monitoring and assuring our compliance with applicable regulations, and we will need to integrate, train and manage a growing employee base. The expansion of our existing businesses, any expansion into new businesses and the resulting growth of our employee base will increase our need for internal audit and monitoring processes, which may be more extensive and broader in scope than those we have historically required. We may not be successful in identifying or implementing all​ Chairman of the processes that are necessary. Further, unless our growth results in an increase in our revenues that is proportionally greater than or equal to the increase in our costs associated with this growth, our business, financial conditionBoard, President and operating results will be adversely affected.Chief Executive Officer Our ability to implement or amend rules could be limited or delayed because of regulation, which could negatively affect our ability to implement needed changes.Christopher A. Isaacson Our exchanges registered with the SEC must submit proposed rule changes to the SEC for its review and, in many cases, its approval. Even where a proposed rule change may be effective upon filing with the SEC, the SEC retains the right to suspend and disapprove such a rule change. Also, the CFTC may stay or disapprove rules that we file with it for CFE or Cboe SEF. The rule review process can be lengthy and can significantly delay the implementation of proposed rule changes that we believe are necessary to the operation of our markets. If the SEC or CFTC delays, including 39 Table of Contents because of a government shutdown, or does not allow one of our exchanges to implement a rule change, this could negatively affect our ability to make needed changes or implement business activities. Similarly, the SEC must approve amendments to our exchange subsidiaries’ certificates of incorporation and bylaws as well as certain amendments to the certificate of incorporation and bylaws of Cboe Global Markets. The SEC may decide not to approve a proposed amendment or may delay such approval in a manner that could negatively affect our ability to make a desired change, which could prevent or delay us from improving the operations of our markets or recognize income from new products. Changes in the tax laws and regulations affecting us, our products and our market participants could have a material adverse effect on our business. Legislation may be proposed, both domestically and internationally, that could add a transaction tax on our products or change the way that our market participants are taxed on the products they trade on our markets. If such proposals were to become law, they could have a negative impact on the securities industry and on us by making transactions more costly to market participants, which may reduce trading and could make our markets less competitive. In addition to proposed tax changes that could affect our market participants, like other corporations, we are subject to taxes at federal, state and local levels, as well as in non-U.S. jurisdictions. Changes in tax laws, regulations or policies or successful claims by tax authorities could result in our having to pay higher taxes, which would in turn reduce our net income. If this occurs, we may experience a higher effective tax rate. We selectively explore acquisition opportunities and strategic alliances relating to other businesses, products or technologies. We may not be successful in integrating other businesses, products or technologies with our business. Any such transaction also may not produce the results we anticipate, which could adversely affect our business, financial condition and operating results. We selectively explore and pursue acquisition and other opportunities to strengthen our business and grow our company. We may enter into business combination transactions, make acquisitions or enter into strategic partnerships, joint ventures or alliances, any of which may be material. The market for acquisition targets and strategic alliances is highly competitive, which could make it more difficult to find appropriate merger or acquisition opportunities. If we are required to raise capital by incurring debt or issuing additional equity for any reason in connection with a strategic acquisition or investment, financing may not be available or the terms of such financing may not be favorable to us and our stockholders, whose interests may be diluted by the issuance of additional stock. For example, in 2019, we entered into a definitive agreement to acquire all of the outstanding shares of stock of EuroCCP, other than the shares of EuroCCP already owned by us (the “Transaction”). The Transaction, which we plan to fund with cash on hand, is expected to close in the first half of 2020 and is subject to the satisfaction or waiver of conditions precedent including (i) the receipt of required regulatory clearances and approvals and (ii) the successful implementation of a supporting Euro 1.5 billion committed syndicated credit liquidity facility at the EuroCCP clearing entity level. Additionally, in February 2020, we acquired Hanweck Associates, LLC (“Hanweck”), a real-time risk analytics company based in New York, and the business of FT Providers, LLC, a portfolio management platform provider based in Chicago, commonly referred to as FT Options (“FT”). The process of integration may produce unforeseen regulatory issues and operating difficulties and expenditures and may divert the attention of management from the ongoing operation of our business and harm our reputation. We may not successfully achieve the integration objectives, and we may not realize the anticipated cost savings, revenue growth and synergies in full or at all, or it may take longer to realize them than expected, any of which could negatively impact our business, financial condition and operating results. We may be required to inject further capital into OCC or EuroCCP or return dividends received back to OCC. OCC is the sole provider of clearing on all of our options and futures exchanges. In addition, Cboe Europe currently owns 20% of EuroCCP, which is one of three interoperable central counterparties used to clear trades conducted on 40 Table of Contents Cboe Europe. On January 24, 2020, upon receipt of SEC approval, OCC established a capital management policy providing that, if OCC’s equity capital falls below certain defined thresholds, OCC can access additional capital through an operational loss fee charged to clearing members. Although Cboe Options does not have a legal or contractual obligation to contribute capital to OCC under OCC’s capital management policy or otherwise, given OCC’s importance to Cboe Options’ business, if OCC were to experience financial difficulties, Cboe Options might nevertheless effectively (but not legally) be required to inject further capital into it in order for OCC to maintain sufficient working or regulatory capital. Likewise, notwithstanding the pending Transaction, if EuroCCP were to experience financial difficulties, Cboe Europe might effectively be required to inject further capital into EuroCCP in order to maintain sufficient working or regulatory capital. In a worst case scenario, OCC or EuroCCP, as applicable, might have their regulatory license suspended or withdrawn, or might have to wind down. This may result in a loss to Cboe Options and Cboe Europe of their respective investments in OCC and EuroCCP and withdrawals of OCC or EuroCCP as clearing houses, which could have a material adverse effect on our business, financial condition and operating results. In addition, while OCC’s new capital management policy is now effective, there remains some degree of uncertainty as to the terms and conditions of the wind-down of OCC’s prior capital plan, under which OCC’s shareholders (including Cboe Options) provided equity capital to OCC and received annual dividends in respect thereof, and which was disapproved by the SEC on February 13, 2019. Depending on the terms on which the prior OCC capital plan is ultimately required to be unwound, Cboe Options could potentially be required to return dividend payments received from OCC during the time the capital plan was in effect. We have outstanding indebtedness, which may decrease our business flexibility and adversely affect our business, financial condition and operating results. As of December 31, 2019, we had $225 million outstanding under our term loan facility, $650 million of senior unsecured notes and no funds outstanding under our revolving credit facility. The financial and other covenants to which we have agreed and our indebtedness may have the effect of reducing our flexibility to respond to changing business and economic conditions, thereby placing us at a competitive disadvantage compared to competitors that have less indebtedness and making us more vulnerable to general adverse economic and industry conditions. Our indebtedness will also increase future borrowing costs, and the covenants pertaining thereto may also limit our ability to repurchase shares of our common stock, increase dividends or obtain additional financing to fund working capital, capital expenditures, acquisitions or general corporate requirements. We are also required to dedicate a larger portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow for other purposes, including working capital, capital expenditures and general corporate purposes. Further, a portion of our borrowings are at variable rates of interest, which exposes us to the risk of increased interest rates unless we enter into offsetting hedging transactions. Our ability to make payments on and to refinance our debt obligations and to fund planned capital expenditures depend on our ability to generate cash from our operations. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. We may not be able to refinance any of our indebtedness on commercially reasonable terms, or at all. If we cannot service our indebtedness, we may have to take actions such as selling assets, seeking additional equity or reducing or delaying capital expenditures, strategic acquisitions, investments and alliances, any of which could impede the implementation of our business strategy or prevent us from entering into transactions that would otherwise benefit our business. Additionally, we may not be able to effect such actions, if necessary, on commercially reasonable terms, or at all. Any of the foregoing consequences could adversely affect our business, financial condition and operating results. Deterioration in our credit profile may increase our costs of borrowing money. As of December 31, 2019, we have investment grade credit ratings from S&P Global Ratings (A-) and Moody’s Investor Service (A3). Ratings from credit agencies are not recommendations to buy, sell or hold our securities, and each rating should be evaluated independently of any other rating. There is no assurance that we will maintain such credit ratings, since credit ratings may be lowered or withdrawn entirely by a rating agency if, in its judgment, the circumstances warrant. If a rating agency were to downgrade our rating below investment grade, our borrowing costs could increase. 41 Table of Contents If our goodwill, long-lived assets, investments in non-consolidated subsidiaries and intangible assets become impaired, the resulting charge to earnings may be significant. We are required to assess investments in non-consolidated subsidiaries and intangible assets for impairment at least annually. Goodwill impairment testing is performed annually in the fiscal fourth quarter or more frequently if conditions exist that indicate that the asset may be impaired. In the future, we may take charges against earnings resulting from impairment. Any determination requiring the write-off of a significant portion of our goodwill, long-lived assets, intangible assets or investments in non-consolidated subsidiaries could adversely affect our results of operations and financial condition. Any decision to pay dividends on our common stock is at the discretion of our board of directors and depends upon the earnings and cash flow of our operating subsidiaries. Accordingly, there can be no guarantee that we will pay dividends to our stockholders. Any decision to pay dividends on our common stock in the future will be at the discretion of our board of directors, which may determine not to declare dividends at all or at a reduced amount. The board’s determination to declare dividends will depend upon our profitability and financial condition, contractual restrictions, restrictions imposed by applicable law and the SEC and other factors that the board deems relevant. As a holding company with no significant business operations of its own, Cboe Global Markets depends entirely on distributions, if any, it may receive from its subsidiaries to meet its obligations and pay dividends to its stockholders. If these subsidiaries are not profitable, or even if they are and they determine to retain their profits for use in their businesses, we will be unable to pay dividends to our stockholders. Certain provisions in our organizational documents and governing law could prevent or delay a change of control. Our organizational documents contain provisions that could block actions that stockholders might find favorable, including discouraging, delaying or preventing a change of control or any unsolicited acquisition proposals for us. These include provisions: ● prohibiting stockholders from acting by written consent; ● requiring advance notice of director nominations and of business to be brought before a meeting of stockholders; and ● limiting the persons who may call special stockholders’ meetings. ​ In addition, our organizational documents include provisions that:43 ​ Executive Vice President and Chief Operating Officer Brian N. Schell ● restrict any person from voting or causing the voting of shares of stock representing more than 20% of our outstanding voting capital stock; and ● restrict any person from beneficially owning shares of stock representing more than 20% of the outstanding shares of our capital stock. Furthermore, our board of directors has the authority to issue shares of preferred stock in one or more series and to fix the rights and preferences of these shares without stockholder approval. Any series of our preferred stock is likely to be senior to our common stock with respect to dividends, liquidation rights and, possibly, voting rights. The ability of the board of directors to issue preferred stock also could have the effect of discouraging unsolicited acquisition proposals, thus adversely affecting the market price of our common stock. Delaware law makes it difficult for stockholders that have recently acquired a large interest in a corporation to cause the merger or acquisition of the corporation against the board’s wishes. Under Section 203 of the Delaware General Corporation Law, a Delaware corporation may not engage in any merger or other business combination with an interested stockholder for a period of three years following the date that the stockholder became an interested stockholder except in limited circumstances, including by approval of the corporation’s board of directors. 42 Table of Contents Furthermore, the European countries where we operate regulated entities, such as the U.K. and Netherlands, may require prior governmental approval before an investor acquires 10% or more of the outstanding shares of our common stock.

We believe that our properties are in good operating condition and adequately serve our current business operations. Generally, our properties are not earmarked for use by a particular segment. Instead, most of our properties are used by two or more segments. We also anticipate that suitable additional or alternative space will be available at commercially reasonable terms for future expansion to the extent necessary. Item 3.Legal Proceedings Cboe incorporates herein by reference the discussion set forth in Note 22 (“Income Taxes”) and Note 24 (“Commitments, Contingencies, and Guarantees”) of the consolidated financial statements included herein. Transaction Fee Pilot In December 2018, the SEC approved a transaction fee pilot in national market system (“NMS”) stocks (the “pilot”). The pilot will subject stock exchange transaction fee pricing, including maker-taker fee-and-rebate pricing models, to new temporary pricing restrictions across two test groups, and require the exchanges to prepare data to be submitted to the SEC. The pilot includes a test group that will prohibit rebates and linked pricing, as well as a test group that will impose a cap of $0.0010 for removing or providing displayed liquidity. Once commenced, the pilot will last for up to two years with an automatic sunset at one year unless extended by the SEC. On February 15, 2019, the Company filed a Petition for Review in the Court of Appeals for the D.C. Circuit (the “D.C. Circuit”) asserting the pilot is unlawful. The pilot was published in the Federal Register on February 20, 2019 and was scheduled to become effective on April 22, 2019. On March 28, 2019, the SEC granted a partial stay of the pilot, agreeing to delay implementing its fee-and-rebate and data-publication requirements until after the D.C. Circuit decides the pending challenges. The data- 43 Table of Contents gathering requirement of the pilot’s pre-pilot period remains in effect. On May 21, 2019, the SEC issued its notice to announce the effective period for the pre-pilot, which was designated as July 1, 2019 through December 31, 2019. On June 3, 2019, the Company, along with other equities exchanges, filed an opening brief with the D.C. Circuit. The SEC filed its opening brief with the D.C. Circuit on July 25, 2019, the exchanges’ reply brief was filed on August 26, 2019 and final briefs were filed on September 10, 2019. Oral arguments were held on October 11, 2019. The pilot may cause the Company’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or challenge the pilot and it may have a material impact on our business, financial condition and operating results if, for example, shifts in order flow away from exchanges were to occur. The Company intends to litigate the matter vigorously.

Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Common Stock The Company’s common stock is listed on Cboe BZX under the trading symbol CBOE. As of January 31, 2020, there were approximately 143 holders of record of our common stock. Dividends Each share of common stock, including restricted stock awards and restricted stock units, is entitled to receive dividend and dividend equivalents, respectively, if, as and when declared by the board of directors of the Company. The Company’s expectation is to continue to pay dividends. The decision to pay a dividend, however, remains within the discretion of the Company's board of directors and may be affected by various factors, including our earnings, financial condition, capital requirements, level of indebtedness and other considerations our board of directors deems relevant. Future debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, our ability to pay dividends. As a holding company, the Company’s ability to declare and continue to pay dividends in the future with respect to its common stock will also be dependent upon the ability of its subsidiaries to pay dividends to it under applicable corporate law.

Overview Cboe Global Markets, Inc., a leading provider of market infrastructure and tradable products, delivers cutting-edge trading, clearing and investment solutions to market participants around the world. The Company is committed to operating a trusted, inclusive global marketplace, and to providing leading products, technology and data solutions that enable participants to define a sustainable financial future. Cboe provides trading solutions and products in multiple asset classes, including equities, derivatives and FX, across North America, Europe, and Asia Pacific. Cboe’s subsidiaries include the largest options exchange and the third largest stock exchange operator in the U.S. In addition, the Company operates one of the largest stock exchanges by value traded in Europe, and owns EuroCCP, a leading pan-European equities and derivatives clearinghouse, BIDS Trading, a leading block-trading ATS by volume in the U.S., MATCHNow, a leading equities ATS in Canada, Cboe Australia, an operator of trading venues in Australia, and Cboe Japan, an operator of trading venues in Japan. Cboe also is a leading market globally for exchange-traded products (“ETPs”) listings and trading. The graphic below provides a brief overview of Cboe’s history: ​ 8 Table of Contents Our Business Cboe Global Markets reports on the following five business segments: ● Options. The Options segment includes options on market indices (“index options”), as well as on the stocks of individual corporations (“equity options”), and options on ETPs, such as exchange-traded funds (“ETFs”) and exchange-traded notes (“ETNs”), which are “multi-listed” options and listed on a non-exclusive basis. These options are eligible to trade on Cboe Options, C2, BZX, EDGX, and other U.S. national security exchanges. Cboe Options is the Company’s primary options market and offers trading in listed options through a single system that integrates electronic trading and traditional open outcry trading on the Cboe Options trading floor in Chicago. C2 Options, BZX Options, and EDGX Options are all-electronic options exchanges, and typically operate with different market models and fee structures than Cboe Options. The Options segment also includes applicable market data revenue generated from the consolidated tape plans, the licensing of proprietary options market data, index licensing, and access and capacity services. ● North American Equities. The North American Equities segment includes listed U.S. equities and ETP transaction services that occur on fully electronic exchanges owned and operated by BZX, BYX, EDGX, and EDGA, equities transactions that occur on the BIDS Trading platform, and Canadian equities and other transaction services that occur on or through the MATCHNow ATS. The North American Equities segment also includes ETP listings on BZX, the Cboe Global Markets, Inc. common stock listing, applicable market data revenue generated from the consolidated tape plans, the licensing of proprietary equities market data, routing services, and access and capacity services. ● Europe and Asia Pacific. The Europe and Asia Pacific segment includes the pan-European listed equities and derivatives transaction services, ETPs, exchange-traded commodities, and international depository receipts that are hosted on MTFs operated by Cboe Europe Equities (Cboe Europe and Cboe NL) and Cboe Europe Derivatives (“CEDX”). It also includes the ETP listings business on RMs and clearing activities of EuroCCP, as well as the equities transaction services of Cboe Australia and Cboe Japan, each operators of trading venues in Australia and Japan. This segment was previously referred to as the European Equities segment but was updated to the Europe segment in the first quarter of 2021 as a result of the launch of Cboe Europe Derivatives, a pan-European derivatives platform, in September 2021. The segment was subsequently updated to Europe and Asia Pacific to reflect the acquisition of Chi-X Asia Pacific in July 2021. Cboe Europe operates lit and dark books, a periodic auctions book, and a Large-in-Scale (“LIS”) trading negotiation facility for UK symbols. Cboe NL, launched in October 2019 and based in Amsterdam, operates similar business functionality to that offered by Cboe Europe, and provides for trading only in European Economic Area (“EEA”) symbols. The new Cboe Europe Derivatives venue offers futures and options based on Cboe Europe equity indices. This segment also includes Cboe Europe, Cboe NL, CEDX, Cboe Australia and Cboe Japan revenue generated from the licensing of proprietary market data and from access and capacity services. ● Futures. The Futures segment includes transaction services provided by the Company’s fully electronic futures exchange, CFE, which includes offerings for trading of VIX futures and other futures products, the licensing of proprietary market data, as well as access and capacity services. ● Global FX. The Global FX segment includes institutional FX trading services that occur on the Cboe FX fully electronic trading platform, non-deliverable forward FX transactions (“NDFs”) offered for execution on Cboe SEF and Cboe Swiss, as well as revenue generated from the licensing of proprietary market data and from access and capacity services. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 16 (“Segment Reporting”) in the notes to our Consolidated Financial Statements for discussion of revenues and certain operational and financial metrics, and operating income (or loss) by business segment. Certain activities within our segments operate globally. For information regarding risks related to our international operations see “Risk Factors.” ​ 9 Table of Contents Competitive Strengths Cboe is a leading provider of market infrastructure and tradable products across cash and spot markets, derivative markets and data and access solutions. Cboe delivers cutting-edge trading, clearing and investment solutions across the globe through a comprehensive ecosystem that helps drive innovation and growth. ● Information is as of December 31, 2021. Key Growth Strategy Initiatives Our strategy is to build one of the world’s largest global derivatives and securities networks to create value and drive growth by: ● Innovating to capture growing demand for trading products and data services, globally.We plan to increase access to data products and trading solutions, provide unrivaled transaction capabilities, have a global presence in high value markets, and develop indices and products to meet growing environmental, social, and governance (“ESG”) needs. In 2021, we delivered on this initiative by launching nearly 24x5 trading for VIX and SPX options, distributing real-time data via Cboe Global Cloud, launching mini-options on the Russell 2000 Index, and preparing to launch in 2022, subject to regulatory approval, Nanos by Cboe, smaller and simpler options designed for retail traders. ● Integrating across ecosystems to increase efficiency and better serve customers. We aim to seamlessly integrate across ecosystems to increase operating efficiency and better serve our customers. We leverage industry-leading technology, apply a non-siloed approach for organic and inorganic initiatives and generate strong free cash flow as we improve operating efficiency. In 2021, we delivered on this initiative by integrating EuroCCP and its technology to launch pan-European derivatives in 2021, integrating our acquisition of BIDS Trading and beginning the integration of Chi-X Asia Pacific. ● Growing by accessing untapped addressable markets. We are expanding and diversifying our revenue opportunity set through both organic investment and merger and acquisition activity. In 2021, we delivered on this initiative by launching Pan-European Derivatives and expanding into new key markets in the Asia-Pacific region. In addition, in 2022, we are planning to further expand into Canada by acquiring the NEO exchange, subject to regulatory approvals and other customary closing conditions, and into the digital asset space by acquiring ErisX, an operator of a U.S.-based digital asset spot market, subject to regulatory approvals and other customary closing conditions. ​ 10 Table of Contents Proprietary Products In addition to providing cash and spot markets, derivative markets, and data and access solutions, we also offer for trading proprietary products and are a leader in the volatility space with our proprietary products. These proprietary products are built both through our in-house research and development staff of the Data and Access Solutions business and our strategic relationships and license agreements with index providers, which are both described below in further detail. Our most frequently traded proprietary products include SPX options and VIX options and futures. SPX Options The S&P 500 Index is an index comprised of 500 large-cap U.S. listed companies. It is one of the most commonly followed indices and is considered a bellwether for the U.S. economy. The SPX options we offer on the S&P 500 Index are exclusive to Cboe and contribute substantially to our volumes and transaction fees. Because of the S&P 500 Index’s status as a bellwether, SPX options are used in many different trading strategies by customers with different goals, including pension funds hedging their equity exposure by buying put options, asset managers seeking enhanced returns by selling covered call options and hedge funds using risk-managed strategies to capture so-called “risk premia” embedded in option prices. We also offer SPX Weeklys options, which have settlements on Mondays, Wednesdays, Fridays and on the last trading day of each month and nearly 24x5 trading in SPX options. We believe these additional expirations provide customers with more precision when hedging overall portfolio risk. Volatility Trading Cboe pioneered the trading of exchange-traded volatility products with its introduction of VIX futures in 2004 and VIX options in 2006. The VIX Index (as defined below), although not directly tradable, is based on the mid-point of real-time quotes of SPX options and is designed to reflect investors’ consensus view of future 30-day expected stock market volatility. The VIX methodology provides the basis for the creation of VIX options and futures. The final settlement value of VIX derivatives is determined on their expiration date through a Special Opening Quotation (“SOQ”) of the VIX Index. The SOQ calculation uses opening trade prices of selected options; unless there is no opening price, in which case the opening price used in the SOQ calculation is the midpoint of the highest bid and lowest offer at the time of the opening. Since we started offering these products, we have seen trading from a number of different customer segments utilizing a number of different trading strategies, including hedging extreme stock market declines, also known as “tail risk” hedging, and risk-managed strategies that seek to capture the relative price changes of expected volatility at different times in the future. We also offer VIX Weeklys options and futures, mini VIX futures, and nearly 24x5 trading in VIX options and futures to provide investors with additional tools to trade volatility. Proprietary Indices We also calculate and disseminate proprietary indices that are licensed for use by third parties or are used as the basis for other proprietary products. These proprietary indices are built both through our in-house research and development staff of the Data and Access Solutions business and our strategic relationships and license agreements with index providers, which are both described below in further detail. Our proprietary indices include: ● volatility indices based on broad-based market indices, such as the S&P 500 and the Russell 2000, ● volatility indices based on ETFs, and ● options strategy benchmark indices, such as the Cboe BuyWrite, PutWrite and Collar indices based on the S&P 500 and Russell 2000, BuyWrite and PutWrite indices based on MSCI EAFE and MSCI Emerging Markets, and BuyWrite indices based on other broad-based market indices. In addition to any transaction fee revenue generated on products created based on these indices, we have granted licenses for third parties to use and sublicense some of these proprietary indices to create third-party indices and products. Accordingly, we generate revenue from proprietary indices by distributing them for reference purposes, using them as the basis for proprietary products and licensing them for use for third-party indices and products. 11 Table of Contents Strategic Relationships The Company has long-term business relationships with several providers of market indices. We license their indices, including on an exclusive basis, as the foundation for indices, index options and other products. The Company also acquires interests in and agrees to work jointly with key providers to develop new products and services that are expected to capitalize on our core competencies and diversify our sources of revenue. Of particular note are the following: ● S&P.

Our exclusive license from FTSE Russell is through 2030. We offer options on the Russell 2000, Russell 1000, Russell 1000 Value and Russell 1000 Growth Indices and mini-options on the Russell 2000 Index. ● MSCI. We have an exclusive license from MSCI Inc. (“MSCI”) until April 1, 2031 to offer U.S.-listed options on ten of MSCI’s indices including the MSCI EAFA and MSCI Emerging Markets indices. We use market data from the trading of these options to calculate several versions of BuyWrite and PutWrite strategy indices. ● IHS Markit. Under our licensing agreement with IHS Markit Ltd., we have the worldwide exclusive license through August 2023 to offer options and futures on indices benchmarked to a diverse array of U.S. corporate bonds. We currently offer futures on high yield and investment grade corporate bond indices. ● Dow Jones. We have the exclusive right during standard U.S. trading hours to offer listed options contracts on the Dow Jones Industrial Average (“DJIA”) and Dow 10 Index, and non-exclusive rights to offer listed options on several other Dow Jones indices including the Dow Jones Utilities Average and Dow Jones Transportation Average.

U.S. Tape Plans We also derive a portion of our revenue from market data fees from U.S. tape plans, including Unlisted Trading Privileges (“UTPs”), the Consolidated Tape Association (“CTA”) and OPRA. Fees, net of plan costs, from UTP, CTA, and OPRA are allocated and distributed to plan participants like us according to their share of tape fees based on a formula, required by Regulation NMS, which may take into account both trading and quoting activity. Our Market Models We operate a variety of derivatives and cash and spot markets. Our markets use a combination of pricing and market models to differentiate them from each other and from our competitors. For our U.S. derivatives options markets, Cboe Options is a hybrid market combining open outcry floor trading with electronic trading. For multi-listed products, we utilize public customer priority, market turner in certain products, participation rights and pro-rata allocation market models, combined with the “classic” pricing model. Under the classic pricing model, professional participants pay transaction fees, public customers generally do not pay transaction fees and market makers compensate brokers for sending order flow to the exchange (known as payment for order flow). For proprietary products, we use price-time or pro-rata allocation, sometimes with public customer priority, and market turner market models, combined with a pricing model where all market participants generally pay fees. Our other three options markets are fully electronic. BZX options utilizes a price-time market model, combined with a “maker-taker” pricing model. Under the maker-taker pricing model, market participants who make the market (a “maker”) generally receive a rebate, while market participants who trade against those markets (a “taker”) pay a transaction fee. EDGX options utilizes customer priority, participation rights and pro-rata allocation market models, combined with the classic pricing model. C2 options utilizes a pro-rata allocation market model, combined with the maker-taker pricing model. For our U.S. derivatives futures market, which is fully electronic, CFE utilizes a price-time market model, combined with a pricing model where all market participants generally pay fees, subject to specified exceptions. For our cash and spot markets, the U.S. equities exchanges, which are fully electronic, offer various market models. BZX equities utilizes a price-time market model, combined with the maker-taker pricing model. EDGX equities utilizes a price-time with retail priority market model, combined with the maker-taker pricing model. BYX equities utilizes a price-time with price improvement for retail customers market model, combined with the “taker-maker” pricing model. Under the taker-maker pricing model, market participants who make the market pay a transaction fee, while market participants who trade against those markets receive a rebate. EDGA equities utilizes a price-time market model, combined with a taker-maker pricing model. In addition to these market models, each of the U.S. equity exchanges provides numerous specific order types that are designed to enhance their respective market models. For our cash and spot markets, MATCHNow, the Canadian equities ATS, which is fully electronic, utilizes a model that combines frequent call matches and continuous execution opportunities in a confidential trading book. The system uses real-time quotes for protected transparent Canadian markets, and orders may be firm or conditional. Firm orders matched within MATCHNow are executed at three levels of price improvement: (1) the mid-point between the Canadian best bid and offer (the “CBBO”); (2) one price increment better than the CBBO or; (3) at the bid or offer for orders that meet a specified large threshold. Trading fees are typically calculated as a function of trade volume and share price. In Europe, following the implementation of the Directive on Markets in Financial Instruments (Directive 2014/65/EU) (“MiFID II”), for the derivatives and cash and spot markets, rebates are generally available if they are tied to a market making scheme or specific service. For our cash and spot markets, BIDS Trading, the U.S. equities ATS market, which is fully electronic, utilizes a sponsored access model to provide anonymous executions in NMS stocks. BIDS Trading provides numerous order types, including both firm and conditional orders. All orders matched within BIDS Trading are executed at or better than the 13 Table of Contents NBBO. BIDS Trading charges fees based on disclosed, objective criteria: (i) means of access; (ii) the type of order; and (iii) the total volume of executions during the calendar month. In Australia, for our derivatives and cash and spot markets, Cboe Australia, a regulated stock exchange, which is fully electronic, utilizes a model that charges a different ad valorem fee rate depending on whether a participant is making or taking liquidity. Fee waivers are also provided to participants registered as market makers, but payments for order flow are prohibited. In Japan, for our cash and spot markets, Cboe Japan, offers two fully electronic displayed markets, Chi-Alpha, which utilizes a price-time market model, combined with the “maker-taker” pricing model and Chi-Select, which utilizes a price-time retail customers focused market model, combined with the “taker-maker” pricing model. Cboe Japan also offers two fully electronic non-displayed markets, Chi-Match, which matches VWAP orders during pre-market hours and Kai-X, which utilizes a price-time market model aiming for primary market mid-point trades. For our FX spot markets, the Cboe FX platform utilizes a price-firmness-time priority market model, combined with a pricing model where users are charged either a flat or tiered commission rate based upon the notional amount traded on the platform. For our FX NDF markets, Cboe SEF and Cboe Swiss platforms utilize a price-firmness-time priority market model and charge a flat commission based upon the notional amount traded on the platform and the capacity in which a participant is trading. Our markets also charge fees for the opportunity to trade or access our markets, including fees for trading-related functionality. To facilitate trading, we also charge fees for certain technology services, terminal and other equipment rights, maintenance services, trading floor space and telecommunications services. Listing Cboe serves as a listing destination for ETPs in the U.S., the UK, Europe and Australia, and its markets are structured and designed for ETP issuers and their investors. In 2021, Cboe added 121 ETP listings in the U.S. and won 25% of all new U.S. ETP listings. There are now 643 ETPs globally listed on Cboe from 84 different issuers. We offer fully-automated opening, closing and halt reopening auctions for our listed securities, which are designed to maximize the efficiency of the price discovery process. Clearing Our subsidiary EuroCCP, a European central counterparty (“CCP”), provides post-trade services, including clearing, to stock exchanges, multilateral trading facilities and for over-the-counter equities trades and derivatives trades. EuroCCP acts as a central counterparty that, for its clearing participants, becomes the buyer to every seller and the seller to every buyer. As a result, it guarantees the timely performance of the obligations of buyers and sellers and takes on the risk of the performance of the transactions that it clears. Additionally, as a critical Financial Market Infrastructure, EuroCCP is subject to strict business continuity requirements and regulatory oversight. In 2021, EuroCCP provided CCP protection for an average of €43 billion of cleared value on a daily basis. Through the process of netting, in 2021, EuroCCP eliminated 72%, or €31 billion of the average daily cleared value, leaving an average daily settlement value of €12 billion. In 2020, EuroCCP provided CCP protection for an average of €41 billion of cleared value on a daily basis. Through the process of netting, in 2020, EuroCCP eliminated 80%, or €30 billion of the average daily cleared value, leaving an average daily settlement value of €11 billion. Customers Our customers generally include financial institutions, trading platforms, institutional and individual investors, and professional traders. Our equities and options customers in the United States include trading permit holders and members of Cboe Options, C2, BZX, BYX, EDGX, and EDGA, which are SEC-registered broker-dealers, and the customers of those broker-dealers. Our Canadian equities customers include subscribers of MATCHNow, which are Canadian registered investment dealers, and certain clients of those dealers. Our Australian customers include trading participants of Cboe Australia, which are Australian registered investment dealers, and certain clients of those dealers. Our Japanese customers include participants of Chi-Alpha, Chi-Select, Chi-Match and Kai-X, which are Japanese registered broker-dealers, and certain clients of those dealers. Our ATS equities participants in the United States include subscribers of BIDS Trading, which are SEC-registered broker-dealers, and certain customers of those broker-dealers.

EuroCCP clearing participants include EEA regulated banks and brokerage trading firms. Our institutional global FX customers include banks, broker-dealers, hedge funds, asset managers, proprietary trading firms, Commodity Trading Advisors, and corporates. Access to our markets and trading rights and privileges depend upon the nature of the customer, such as whether the individual or firm is (or is eligible to become) a trading permit holder, trading privilege holder, member, participant, or subscriber of one of our markets. Competition The industry in which we operate is intensely competitive. We believe we face competition on a number of factors, including: ● price, quality and speed of our trade and clearing execution; ● functionality and ease of use of our trading and clearing platforms; ● reliability, integrity, range and functionality of our products and services; ● integrity of our marketplaces; ● technological innovation and adaption; ● our brand awareness; and ● our reputation. We believe that we compete favorably with respect to these factors through a variety of methods, including: ● offering access to a broad array of products and services, including proprietary products and market data; ● offering fee schedules and pricing models that both attract order flow and provide incentives to liquidity providers; ● providing advanced technology that offers broad functionality, low latency, fast execution, ease of use, scalability, reliability and security; ● offering efficient, transparent and liquid marketplaces; ● offering deep and liquid markets with opportunities for price improvement; ● offering broad trading platform access in the EU; ● maintaining close relationships with customers; and ● providing customers with a comprehensive source of information on options and ETPs as well as extensive options education. In our proprietary products, we compete against other futures exchanges and swap execution facilities that offer similar products, as well as against financial market participants that offer similar over-the-counter derivatives. We also compete against certain multi-listed options products, such as options on SPY, which may offer similar market exposure of our proprietary products, such as SPX options. The multi-listed options industry is extremely competitive. We expect this trend to continue. As of December 31, 2021, we compete with 12 U.S. options exchanges, in large part due to existing exchange holding companies opening new exchanges that offer different markets and pricing models on existing technology. Most of the equity and ETP options listed and traded on our exchanges are also listed and traded on the other exchanges. In addition, the options exchanges that we compete with set fees and rebates to attract multi-listed options business to their exchanges, which has historically reduced the net revenue per contract that we generate from multi-listed options, and the options exchanges that we compete with structure their options businesses in partnership with established market participants, such as consolidators, and other order flow providers, to increase their volume traded. Our U.S. listed equity securities and listing services and the BIDS Trading ATS compete against 12 other exchanges as of December 31, 2021, and several other ATSs and single dealer platforms. Market participants have multiple venues for the execution of orders, including national securities exchanges and numerous off-exchange venues, including other ATSs and broker-dealers who internalize orders off-exchange. Additionally, issuers have multiple venues for the listing of their products. In Canada, our equities ATS, MATCHNow, competes with several Canadian exchanges and other ATSs. In Australia, our exchange, Cboe Australia, competes with other Australian exchanges and ATSs. In Japan, our equities exchanges and ATSs, compete with several Japanese exchanges and other ATSs. 15 Table of Contents The market for execution and clearing services in Europe became more competitive following the introduction of MiFID II and the Regulation on Markets in Financial Instruments (Regulation (EU) No 600/2014) (“MiFIR”). Furthermore, MiFID II and MiFIR placed more onerous conditions on trading venues and investment firms and restricted certain types of trading activity. Our major competitors in Europe include national stock exchanges, other pan-European MTFs, European clearinghouses, dark pools, and systematic internalizers. The global FX market remains severely fragmented, with transparent automated marketplaces such as Cboe FX challenging a small number of similarly situated competitors. While the global FX market has experienced a shift from competing interbank platforms to ECNs, the electronification of the spot and NDF FX market may encounter resistance from customers that still prefer to utilize the phone, instant chats, terminals and key banking relationships for price discovery and trading. Furthermore, electronification of the FX market appears to be experiencing more resistance outside the United States. The electronic spot FX market is also intensely competitive, with over 10 other venues competing for market share as of December 31, 2021. Cboe measures and reports on market share against a narrower set of competitors, included in those venues. In addition, our data and access solutions face competition from other securities exchanges, technology companies, third-party market data providers, and information and software vendors, which have their own substantial market data distribution capabilities that serve as alternative means for receiving open market data feeds instead of connecting directly to our exchanges or trading venues. The sale of our proprietary data products is also under competitive threat from ATSs and trading venues that offer similar products. Distributors and consumers of our market data may also use our market data as an input into a product that competes against one of our traded or cleared products. Technology Cboe Trading Technology The trading platform for our equities, options, and futures markets is developed, owned, and operated in-house and is designed to optimize reliability, speed, scalability, and versatility. Each of our exchanges provide different market models, appealing to different user bases, and the trading technologies support all of them. Further, the technologies are designed to support many specialized features for each of the markets, such as: dark pools, trade reporting facility, systematic internalizer, Large-in-Scale, smart order routing, FLEX options, 24x5 trading, and hybrid trading (combining electronic and open outcry). In addition, Cboe and its applicable subsidiaries operate separate trading and/or clearing platforms, as applicable, for BIDS Trading, MATCHNow, EuroCCP, Global FX, Cboe Australia, and Cboe Japan. Our trading platforms have experienced very low operational downtime and low latency. The trading platforms use readily available hardware, thereby minimizing capital outlays required for each new market entry. Also, in order to continue to implement new enhancements to our trading platforms, new releases of software are generally deployed routinely in all of the applicable markets. Disaster Recovery We operate and maintain geographically diverse disaster recovery facilities for all of our markets. We expect that the disaster recovery facilities can be up and running in a short period of time and in certain instances we work with our market participants to try to quickly reopen marketplaces. We regularly test our data center recovery plans and periodically carry out weekend tests using our back-up data centers, as well as an annual test with our U.S. trading participants. In Canada, as required by local regulations, MATCHNow conducts internal testing of its disaster recovery data processing capabilities at least annually, and it participates in the bi-annual testing coordinated by IIROC. In Australia and Japan, Chi-X Asia Pacific conducts internal testing of its disaster recovery data processing capabilities at least annually. In Europe, we also regularly test our data center recovery plans and periodically carry out weekend tests which use our back-up data center, as well as an annual test with our European trading participants. We continue to work to improve both the availability of our technology and our disaster recovery facilities. Routing and Clearing OCC is the sole provider of clearing on all of our U.S. options and futures exchanges. National Securities Clearing Corporation (“NSCC”), a subsidiary of the Depository Trust and Clearing Corporation (“DTC”), is the sole provider of clearing on our U.S. listed equity exchanges. The Canadian Depository for Securities (“CDS”) is the sole provider of clearing on all equities transactions occurring on MATCHNow. With respect to Australian equities and derivatives, Cboe Australia delivers matched trades of its customers to ASX Clear Pty Ltd and ASX Settlement Pty Ltd. ASX Clear Pty Ltd acts as a central counterparty on all transactions occurring on Cboe Australia. The Japan Securities Clearing Corporation 16 Table of Contents (“JSCC”) is the sole provider of clearing on all equities transactions occurring on Cboe Japan’s Chi-Alpha, Chi-Select,Chi-Match and Kai-X. BofA Securities, Inc. (“BOA”) is the sole provider of clearing on all equities transactions occurring on BIDS Trading. Cboe Europe Equities and Derivatives relies on LCH Limited and LCH SA (“LCH”), EuroCCP, which is described above, and SIX x-clear Ltd (“SIX x-clear”) to clear trades in European listed equity securities and derivatives as part of an interoperable clearing model. Cboe Trading is a routing broker-dealer used by our four U.S. equities exchanges and our four U.S. options exchanges, including the electronic platform portion of Cboe Options. Cboe Trading’s clearings firms are Wedbush Securities, Inc. (“Wedbush”) and Morgan Stanley & Co. LLC (“Morgan Stanley”). Regulatory Environment and Compliance Various aspects of our business are subject to regulation by the SEC, CFTC, FINRA, IIROC, the Ontario Securities Commission (the “OSC”), the Australian Securities & Investments Commission (“ASIC”), JFSA, JSDA, ESMA, FCA, the Central Bank of the Netherlands (“DNB”), AFM, and other international regulatory authorities where our exchanges or EuroCCP may be authorized to act as foreign exchanges or provide clearing services, and market participants may be subject to regulation by the SEC, CFTC, FINRA, National Futures Association (“NFA”), FCA, Board of Governors of the Federal Reserve, U.S. Department of the Treasury and/or foreign regulators. The following is a discussion of the more significant areas of regulation of us by the SEC, the CFTC, and certain European regulators. Recent Developments Laws and regulations regarding our business are frequently modified or changed to address perceived problems, new products, or competition or at the request of market participants. The following is a brief discussion of recent regulatory developments that may significantly impact our business. United States Consolidated Data Plan Order On May 6, 2020, the SEC issued an order (the “Consolidated Data Plan Order”) that would require U.S. equities exchanges and FINRA to develop and file a new consolidated data plan (the “Plan”) that would replace the three current U.S. equities tape data plans and require certain governance provisions, such as changes to the voting structure. Pursuant to the Consolidated Data Plan Order, we and the other U.S. equities exchanges and FINRA were required to file the proposed Plan for public comment before the SEC takes any definitive action on such new plan. The proposed Plan was filed on August 11, 2020 and on August 6, 2021 the SEC approved such Plan. The Plan was subsequently challenged by exchanges and the courts granted a stay of the Plan. Until a decision is made by the courts, the current data plans will continue to govern. Our equities exchanges, BZX, BYX, EDGX, and EDGA, may require additional resources to comply with or challenge the Consolidated Data Plan Order and the Plan may have a material impact on our business, financial condition and operating results if, for example, there is a negative impact on the applicable market data revenues that we receive that are generated from such new plan. See “Risk Factors” and “Legal Proceedings” for more information. Financial Transaction Taxes A number of federal, state and local jurisdictions in the U.S. and EU Member States have considered a financial transaction tax, but many details remain to be discussed and agreed, including how to assess the tax.Additionally, legislation has been proposed from time to time on a federal level that would introduce in the U.S. mark-to-market tax treatment for all derivatives contracts and require gains and losses be taxed at ordinary income tax rates. Implementation of such taxes could result in a reduction in volumes and liquidity, which would have a negative impact on our operations. See “Risk Factors” for more information. Market Data Infrastructure Rule On December 9, 2020, the SEC issued a Market Data Infrastructure Final Rule, which makes significant additions to the content available on the Securities Information Processors (“SIPs”) and replaces the exclusive processors with a competing consolidator model. The implementation of the new rules could cause Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or to challenge the new rules and they may have a 17 Table of Contents material impact on our business, financial condition and operating results if, for example, there are lower SIP plan revenues or we must reduce the fees we charge for market data. See “Risk Factors” and “Legal Proceedings” for more information. Europe Capital Markets Union The European Council (“E.C.”) has highlighted one of its top priorities as being the establishment of a fully functioning, well-regulated Capital Markets Union (“CMU”). An Action Plan of concrete steps was set out in September 2015, and an update of the list of initiatives was published in September 2016. In November 2019, the E.C. set up a High Level Forum on CMU, resulting in a final report published in June 2020. On September 24, 2020, the E.C. published a new CMU Action Plan, and on November 25, 2021, published a set of legislative proposals in furtherance of the CMU, including proposals to amend the Markets in Financial Instruments Regulation (“MiFIR”) described in the EU Transparency Rules section below. This therefore remains an ongoing project for the E.C., which may result in additional regulation or legislation. In November 2021 the EU Commission published an update regarding progress against the CMU Action Plan alongside a number of new legislative proposals designed to contribute to the objectives of CMU. These included proposals to: ● Create a European Single Access Point (“ESAP”) which will be a common source of public, free information about EU companies and investment products, regardless of where in the EU they are located or originated. ● Amendments to the ELTIF framework to promote long-term investments through European Long-Term Investment Funds (“ELTIFs”). ● Making funding more diversified for companies by reviewing the Alternative Investment Fund Managers Directive (“AIFMD”). ● Enhancing market transparency by reviewing the Markets in Financial Instruments Regulation (“MiFIR”). OTC Derivatives, Central Counterparties and Trade Repositories Regulation (EU) No 648/2012 of the European Parliament and of the Council of July 4, 2012 on OTC derivatives, central counterparties and trade repositories (the “European Market Infrastructure Regulation” or “EMIR”) sets out rules relating to over-the-counter (“OTC”) derivatives markets, central counterparties and trade repositories. The rules introduce a reporting obligation for OTC derivatives markets, a clearing obligation for eligible OTC derivatives markets, measures to reduce counterparty credit and operational risk for bilateral OTC derivatives markets, CCPs, and trade repositories, and rules on the establishment of interoperability between CCPs. EMIR was enhanced and amended in June 2019. In addition, regulation governing the authorization and supervision of Central Securities Depositories (“CSDR”) was approved in September 2014, with the publication of most “Level 2” Regulatory Technical Standards in March 2017, with implementation in March 2019. CSDR may result in the introduction of mandatory buy-ins for OTC business in 2022 although recent communications from ESMA and the EU Commission have indicated that the intended implementation date of February 1, 2022 will be postponed pending a further review of those proposals by the EU Commission during 2022. Rules in relation to the calculation and collection of cash penalties are expected to come in to force in February 2022. The Central Counterparty Recovery and Resolution Regulation (“R&R Regulation”) was published in the Official Journal of the EU on January 22, 2021, which may, among other things, increase the amount of prefunded capital EuroCCP is required to maintain. This additional prefunded capital may be required to be drawn before any recovery measures can be taken by the CCP. On July 12, 2021, and November 18, 2021, ESMA proposed a set of level 2 and level 3 guidance pursuant to the R&R Regulation. As European authorities finalize and potentially adopt level 2 and 3 guidance, the final R&R Regulation may have a material adverse effect on our clearing business, financial condition and operating results. EU Transparency Rules On November 11, 2021, the European Council (“E.C.”) published its proposal for a review of EU market structure legislation, including proposed amendments to Markets in Financial Instruments Regulation (“MiFiR”) and Directive 2014/65/EU on markets in financial instruments (“MiFID II”). The proposal includes, among other provisions, provision for 18 Table of Contents a consolidated tape for the EU and changes to the transparency regime for equities. These proposals are expected to be implemented in late 2023 or early 2024. In addition, the European Securities and Markets Authority (“ESMA”) also published its proposal for a review of EU transparency rules. The proposal includes, among other provisions, provision for increased pre-trade transparency for periodic auctions and post-trade flagging. These proposals may be implemented in the second half of 2022 although they may also be incorporated into the wider MiFiR review. As proposed, these proposals may have a material adverse effect on our business, financial condition and operating results. See “Risk Factors” for more information. Compliance U.S. Securities Industry Federal securities laws have established a two-tiered system for the regulation of securities exchanges and market participants. The first tier consists of the SEC, which has primary responsibility for enforcing federal securities laws. The second tier consists of self-regulatory organizations (“SROs”), which are non-governmental entities that must register with and are regulated by the SEC. The Exchanges are SROs, each registered under Section 6 of the Exchange Act of 1934, as amended (“Exchange Act”) as a “national securities exchange,” and are subject to oversight by the SEC. SROs are an essential component of the regulatory scheme of the Exchange Act for providing fair and orderly markets and protecting investors. To be registered as a national securities exchange, an exchange must successfully undergo an application and review process with the SEC prior to beginning operations. Among other things, the SEC must determine that the SRO has the ability to comply with the Exchange Act and to enforce compliance by its members and persons associated with its members with the provisions of the Exchange Act, the rules and regulations thereunder and the rules of the exchange. In general, an exchange SRO is responsible for operating its trading platforms consistent with its rules, and regulating its members through the adoption and enforcement of rules governing the business conduct of its members. The rules of the exchange must also assure fair representation of its members in the selection of its directors and administration of its affairs and, among other things, provide that one or more directors be representative of issuers or investors and not be associated with a member of the exchange or with a broker or dealer. Additionally, the rules of the exchange must be adequate to ensure fair dealing and to protect investors and may not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Exchange Act. As registered national securities exchanges, virtually all facets of our Exchange operations are subject to the SEC’s oversight, as prescribed by the Exchange Act. The Exchange Act and the rules thereunder impose on us many regulatory and operational responsibilities, including record keeping and the day-to-day responsibilities for market operations and broker-dealer oversight. Furthermore, as SROs, the Exchanges are potentially subject to regulatory or legal action by the SEC or other interested parties. The SEC also has broad enforcement powers to censure, fine, issue cease-and-desist orders, prohibit us from engaging in some of our businesses, suspend or revoke our designation as a registered securities exchange or remove or censure any of our officers or directors who violate applicable laws or regulations. For example, in 2013, Cboe Options and C2 and, in 2015, EDGX and EDGA, entered into consent orders with the SEC, under which they were censured, ordered to cease and desist from violating certain sections of the Exchange Act, paid fines and agreed to complete certain undertakings. We have certified to the completion of these undertakings and are no longer required to certify. As part of its regulatory oversight, the SEC conducts periodic reviews and inspections of exchanges, and the Exchanges have been subject to such routine reviews and inspections. To the extent such reviews and inspections result in regulatory or other changes, we may be required to modify the manner in which we conduct our business, which may adversely affect our business. We collect certain fees to cover Section 31 fees charged to the Exchanges by the SEC and certain fees derived from our regulatory function and fines in connection with our disciplinary proceedings. The Exchanges are responsible for the ultimate payment of Section 31 fess to the SEC. Additionally, under the rules of each of our exchanges, as required by the SEC, any revenue derived from the regulatory fees and fines cannot be used for non-regulatory purposes. Section 19 of the Exchange Act also provides that we must submit to the SEC proposed changes to any of the Exchanges’ rules, including revisions of their certificates of incorporation, bylaws, or other governing documents of the 19 Table of Contents SROs or their parent companies. The SEC will typically publish the proposal for public comment, following which the SEC may approve or disapprove the proposal, as it deems appropriate. Certain categories of rule changes, like fee changes, can be effective on filing, but the SEC retains the ability to suspend or reject such filings within a prescribed period of time. Canadian Securities Industry MATCHNow is subject to comprehensive regulation and oversight by its primary provincial securities regulatory authority, the OSC, and by IIROC. The regulations applicable to MATCHNow cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability. Australian Securities Industry Cboe Australia is subject to comprehensive regulation and oversight by the ASIC. The regulations applicable to Cboe Australia cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability. Japanese Securities Industry Cboe Japan is subject to comprehensive regulation and oversight by the JFSA and the JSDA. The regulations applicable to Cboe Japan cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability. Futures and Swaps Industry-CFE and Cboe SEF The operations of each of CFE and Cboe SEF are subject to regulation by the CFTC under the Commodity Exchange Act. The Commodity Exchange Act generally requires that futures trading in the United States be conducted on a designated contract market and, in some cases, requires swaps trading to be conducted on swap execution facility (“SEF”) or designated contract market (“DCM”). The Commodity Exchange Act and CFTC regulations establish criteria for an exchange to be designated as a contract market on which futures and futures options contracts may be traded, and for a trading platform to be designated as a swap execution facility on which certain swaps may be traded. Designation as a contract market or swap execution facility for the trading of specified futures or swaps contracts is non-exclusive. This means that the CFTC may permit additional exchanges or trading platforms to be contract markets or swap execution facilities for trading the same or similar contracts. CFE is a designated contract market, and Cboe SEF is a swap execution facility, each of which is subject to the oversight of the CFTC and to a variety of ongoing regulatory and reporting responsibilities under the Commodity Exchange Act. As a designated contract market, CFE is required to comply with the applicable core principles and regulations under the Commodity Exchange Act, as is Cboe SEF as a swap execution facility. Each of CFE and Cboe SEF has surveillance and regulatory operations and procedures to monitor and enforce compliance by trading privilege holders with CFE rules, and by participants with Cboe SEF rules, as applicable. If CFE or Cboe SEF fails to comply with applicable laws, rules or regulations, it may be subject to censure, fines, cease-and-desist orders, suspension of its business, removal of personnel or other sanctions, including revocation of CFE’s designation as a contract market or Cboe SEF’s designation as a swap execution facility. Europe Cboe Europe is located in London and is subject to regulation in the UK and to certain European regulations. The current UK regulatory system was established by the Financial Services Act 2012 (“FSA12”), which amended the Financial Services and Markets Act 2000. The legislation replaced the previous financial services regulator, the Financial Services Authority, with three new bodies: The Financial Policy Committee (“FPC”), The Prudential Regulation Authority, and the FCA. Financial conduct of markets, including activity on, and the operation of, markets is regulated by the FCA, which is an independent non-governmental body, given statutory powers by the FSA12. The FCA has three statutory objectives: to secure an appropriate degree of protection for consumers; to protect and enhance the integrity of the UK financial system; and to promote effective competition in the interests of consumers in the markets for financial services. The FCA is accountable to Her Majesty’s Treasury Ministers and, through them, to Parliament. 20 Table of Contents EuroCCP and Cboe NL are located in Amsterdam and subject to Dutch law and regulation. The current Dutch regulatory system was established by the Act on Financial Supervision. Financial conduct of markets, including activity on, and the operation of, markets is regulated by the AFM. Financial conduct of CCPs, including clearing activity is regulated by the AFM and DNB. The AFM is an independent non-governmental body, given statutory powers by the Act on Financial Supervision. The AFM has three strategic objectives: to promote the fair and conscientious provision of financial services, to promote the fair and efficient operation of the capital markets and to contribute to the stability of the financial system. The AFM is accountable to the Minister of Finance. The DNB is the Dutch central bank, financial sector supervisor and resolution authority. The DNB is committed to a stable financial system: stable prices, solid financial institutions and properly functioning payment transfers. Much of the UK and Dutch financial services regulation originates from the EU. Such regulation includes organizational requirements, capital resources requirements and the specific requirements for RMs and MTFs and are applicable to both Cboe Europe and Cboe NL. MiFID II and MiFIR set out requirements for RMs and MTFs with respect to the establishment of transparent and non-discretionary rules and procedures governing access and for fair and orderly trading and the efficient execution of orders, as well as to facilitate the efficient settlement of transactions conducted on RMs and MTFs and monitoring compliance with the rules. EMIR governs the CCPs operating in the EU and requires them to meet common risk management, governance and capital adequacy standards. The regulatory functions required of Cboe Europe Equities and Derivatives, including EuroCCP, by MiFID II, MiFIR, EMIR and other relevant legislation and regulations are performed by in-house staff. Cboe Europe Equities and Derivatives utilizes the same state-of-the-art, real-time surveillance system is used on the U.S. to monitor trading and market activities on BZX, BYX, EDGA, and EDGX. EuroCCP utilizes proprietary risk management software to monitor settlement and funding flows. Global FX While the global institutional spot FX market remains largely unregulated, the enactment of the Dodd Frank Act and its related regulations in the United States and the ongoing implementation of MiFID II and MiFIR in Europe have impacted the regulatory landscape for currency derivative products. For example, certain standardized currency derivative products are required to trade on an organized trading venue such as a SEF or DCM in the United States or on an MTF or organized trading facility in Europe. Moreover, even in the largely unregulated spot FX market, this movement towards additional trading standards and norms is highlighted by the publication of the FX Global Code in 2017 by the Global Foreign Exchange Committee, reflecting principles of good conduct for the wholesale FX market, and whose publication may lead to additional oversight in the global FX market. Cboe FX issued a Statement of Commitment declaring its commitment to conduct its FX market activities in a manner consistent with the principles of the FX Global Code. Following the publication of the FX Global Code regulators are taking a new look at the spot FX market, and any decision to impose new regulations may affect our spot FX business line. Broker-Dealer Cboe Trading and BIDS Trading are registered broker-dealers regulated by the SEC, FINRA, other SROs of which they are members and various state securities regulators. Cboe Trading currently operates as a routing broker-dealer for sending orders from the Exchanges to other venues for execution, including routing orders among the Exchanges. Cboe Trading is considered a facility of each of the Exchanges and is subject to the rules of the Exchanges. The Exchanges are responsible for enforcing Cboe Trading’s compliance with their rules, including to ensure Cboe Trading is not given preferential treatment. BIDS Trading currently operates an ATS, which is designed to bring counterparties together to anonymously trade large blocks of U.S. equities. BIDS Trading is not a member of any of the U.S. national securities exchanges and is not subject to exchange rules. Cboe Trading and BIDS Trading are subject to SEC and SRO rules, as applicable, and, as registered broker-dealers, regulations concerning all aspects of their businesses, including trading practices, order handling, best execution, anti-money laundering, handling of material non-public information, safeguarding data, reporting, capital adequacy, record retention, market access and the conduct of their officers, employees and other associated persons. The SEC, SROs and state securities commissions may conduct proceedings which can result in injunctions or other sanctions, censures, fines, the issuance of cease and desist orders or the suspension or expulsion of a broker-dealer, its officers or employees. The SEC and FINRA impose certain minimum capital requirement rules that require notification when a broker-dealer’s net capital falls below certain predefined criteria, dictate the ratio of debt to equity in the regulatory capital composition of a broker-dealer, constrain the ability of a broker-dealer to expand its business under certain circumstances and impose certain requirements that may have the effect of prohibiting a broker-dealer from distributing or withdrawing capital. 21 Table of Contents In addition, the ATS operated by BIDS Trading is not a registered national securities exchange or a facility thereof, as such, Cboe intends to maintain the BIDS ATS as an independently managed and operated trading venue, separate from and not integrated with the Exchanges. The Chief Executive Officer of BIDS Trading is expected to lead BIDS Trading as an independent business within Cboe, reporting into an independent committee of the board of Cboe Global Markets. Further, Cboe Trading will not route orders to BIDS Trading on behalf of the Exchanges. Cboe Global Markets Certain aspects of Cboe Global Markets are also subject to SEC, FCA and AFM oversight, including certain ownership and voting restrictions on its stockholders. The focus of the SEC’s regulation of Cboe Global Markets is to assure fair representation of members in the selection of the directors of the Exchanges, public participation in the governance of the Exchanges and that the Exchanges can satisfy their regulatory responsibilities under the Exchange Act. Furthermore, the SEC requires that Cboe Global Markets give due regard to the preservation of the independence of the self-regulatory function of the Exchanges and to Cboe Global Markets’ obligations to investors and the general public. The SEC also requires that Cboe Global Markets not take any actions that would interfere with the effectuation of any decisions by the Board of Directors of any of the Exchanges relating to its regulatory functions or the structure of the market that it regulates or that would interfere with the ability of such Exchange to carry out its responsibilities under the Exchange Act. To the extent that Cboe Global Markets’ business activities involve or relate to the Exchanges, the officers and directors of Cboe Global Markets may be deemed to be officers and directors of the exchanges for purposes of and subject to oversight under the federal securities laws. Accordingly, the SEC may exercise direct supervision and disciplinary authority over certain Cboe Global Markets’ activities and those activities may be subject to SEC approval and, in some cases, public notice and comment. In addition, Cboe Global Markets indirectly holds all of the issued share capital and voting rights in Cboe Europe and its wholly owned subsidiaries, Cboe Chi-X Europe and Cboe NL. As a result, we and any person who holds, or has voting power with respect to, 10% or more of the outstanding shares of Cboe Global Markets common stock may be subject to certain regulatory requirements under UK and Dutch law. U.S. Regulatory Responsibilities Our U.S.-based exchanges are responsible for assessing the compliance of their TPHs or members, including Cboe Trading, with the respective exchange’s rules and the applicable rules of the SEC and/or CFTC. The main activities that the exchanges, as applicable, are required to monitor for the purpose of compliance with these rules include: ● surveillance designed to detect violations of exchange trading rules; ● surveillance designed to detect violations of SEC and/or CFTC rules; ● investigation of matters involving potential rule violations; ● the investigation of complaints about possible rule violations brought by customers, TPHs, members or other SROs; and ● the examination of TPHs or members for compliance with rules such as those related to net capital, books and records, market access and other matters related to the TPHs’ or members’ exchange business functions. In order to ensure market integrity, we regulate and monitor our TPHs’ and members’ trading activities by using both our employees and third parties under regulatory services agreements (“RSAs”). See “Regulatory Agreements” below. Providing effective regulation is important for attracting and retaining the confidence and participation of market-makers, broker-dealers and institutional and retail investors. We expend considerable time, financial resources and effort to ensure that the exchanges’ rules and regulations conform to regulatory best practices within the securities and futures exchange industries and within the regulatory regime overseen by the SEC and CFTC, our primary regulators. In order to support our efforts and those of our market participants to comply with applicable law and our exchange rules, we developed a regulatory program to monitor market activity on our exchanges. All of our Exchanges and CFE are participants in the Intermarket Surveillance Group (“ISG”). ISG is an international information-sharing cooperative governed by a written agreement that provides for a comprehensive surveillance sharing arrangement. In addition to the agreement for confidential information sharing, the ISG provides a framework for the coordination of regulatory efforts among exchanges trading securities, commodity futures and related products to address potential intermarket manipulations and trading abuses. 22 Table of Contents As part of the regulatory program, each of our Exchanges and CFE have rules pertaining to their respective disciplinary processes. U.S. Regulatory Agreements The Exchanges and CFE have entered into agreements under which third parties have agreed to perform regulatory functions on behalf of our markets (e.g., RSAs). As discussed below, in addition, in certain other instances for our Exchanges, a third party has been allocated the regulatory responsibility under Rule 17d-1 or Rule 17d-2 under the Exchange Act, while in others, we retain the regulatory responsibility for the activities. Regulatory Services Agreement with FINRA The Exchanges have entered into agreements with FINRA under which FINRA has agreed to provide regulatory services to the Exchanges. Under these agreements, FINRA performs certain regulatory functions on behalf of the Exchanges and, to avoid any potential conflicts of interest concerning the regulation and oversight of Cboe Trading, certain regulatory services specific to Cboe Trading. The Exchanges remain responsible for the regulation of their TPHs, members and marketplaces, and retain the authority for bringing disciplinary actions against their TPHs and members, although FINRA performs certain disciplinary-related functions on behalf of the Exchanges. Over the course of 2019 through 2021, certain regulatory and disciplinary-related functions that FINRA had performed on behalf of the Exchanges have been moved back in-house from FINRA. Regulatory Services Agreements with NFA and OCC Through December 31, 2020, the NFA performed regulatory functions on behalf of CFE pursuant to an RSA with CFE. The RSA has been terminated and, starting January 1, 2021, these regulatory functions were moved in-house from the NFA. In addition, OCC has also performed and continues to perform certain regulatory functions on behalf of CFE pursuant to an RSA with CFE. CFE also performs other regulatory and disciplinary-related functions in-house. Whether performed under an RSA or in-house, CFE retains overall responsibility for the regulation of its marketplace and for bringing disciplinary actions. CFE is also a party to cooperative and regulatory information sharing agreements with other SROs and is a member of the ISG, described above. Rule 17d-1 Designations and Rule 17d-2 Agreements Section 17(d) of the Exchange Act and the related Exchange Act rules permit SROs to allocate certain regulatory responsibilities to avoid duplicative oversight and regulation. Under Exchange Act Rule 17d-1, the SEC designates one SRO to be the designated examining authority (“DEA”) for each broker-dealer that is a member of more than one SRO. The DEA is responsible for the regulatory oversight of applicable financial responsibility rules pertaining to that broker-dealer. Cboe Options is the DEA for several of its TPHs. Cboe Trading’s assigned DEA is FINRA. Exchange Act Rule 17d-2 permits SROs to enter into agreements, commonly called Rule 17d-2 agreements, which are approved by the SEC and concern the allocation of regulatory responsibility for rules applicable to TPHs and members that those SROs have in common. The Exchanges have entered into certain bi-lateral Rule 17d-2 agreements under which FINRA is allocated responsibility for enforcing certain federal securities laws and certain exchange rules that are common with FINRA rules. The Exchanges have entered into certain other multi-party Rule 17d-2 agreements that allocate responsibility among the participating SROs, which may include the Exchanges, for oversight of their allocated common members compliance with certain rules governing, among other items, options related sales practices, options related market surveillance, insider trading, NMS and consolidated audit trail NMS plan (“CAT”) compliance. National Market System Plans We are member participants of several NMS plans including, but not limited to, the following: Cboe Options, C2, BZX, and EDGX are member exchanges in OPRA, which is the designated securities information processor for market information that is generated through the trading of exchange-listed securities options in the United States, and it disseminates certain core trading information, such as last sale reports and quotations. Cboe Options, BZX, BYX, EDGA, and EDGX also participate in the CTA/CQ and the UTP Plans, which perform analogous services for the U.S. equities market. Securities Information Automation Corporation (“SIAC”) acts as the “processor” for OPRA and the CTA/QC Plans. Nasdaq Stock Market, LLC acts as the processor for the Nasdaq Unlisted Trading Privileges Plan. Also, see “Regulatory Environment and Compliance - Recent Developments - United States - Consolidated Data Plan Order”, “Risk Factors” and “Legal Proceedings” for more information regarding the Consolidated Data Plan Order and the Plan. 23 Table of Contents Cboe Options, C2, BZX, and EDGX are also parties to the Options Order Protection and Locked/Crossed Market Plan, which is designed to prohibit trade-throughs and avoid locked/crossed markets. Cboe Options, C2, BZX, and EDGX are also parties to the Options Listing Procedures Plan, which sets forth the procedures that the options exchanges must follow to list new options. Cboe Options, BZX, BYX, EDGA, and EDGX are also parties to the NMS plan for the selection and reservation of securities symbols. Under the Options Regulatory Surveillance Authority Plan (“ORSA Plan”), U.S. securities options exchanges are permitted to act jointly in the administration, operation and maintenance of a regulatory system for the surveillance, investigation and detection of the unlawful use of undisclosed, material information in trading in one or more of their markets. The ORSA Plan is intended to enhance the effectiveness and efficiency with which the exchanges regulate their respective markets and to avoid duplication of certain regulatory efforts. FINRA operates the ORSA Plan facility for options insider trading. The CAT involves the creation of a comprehensive audit trail that strives to enhance regulators’ ability to monitor trading activity in the U.S. securities markets through a phased implementation. Upon final implementation of the provisions of the CAT, data will be required to be reported to a central repository the following day by each SRO (a “Plan Participant”) and broker-dealer (an “Industry Member”). On November 15, 2016, the SEC approved the CAT. The first of various phases of CAT were originally required to begin in November 2017; however, there have been some delays. In 2017, Thesys CAT LLC (“Thesys”), a subsidiary of Thesys Technologies, LLC, was selected as the plan processor with the responsibility to build and operate the CAT. The first phase of CAT ultimately went live in November 2018, at which time we and other SROs/Plan Participants began initial reporting to the CAT. In 2019, Thesys was replaced by a new plan processor, FINRA CAT, LLC, a subsidiary of FINRA. The second phase for Industry Member order and trade file submissions is now live and began in June 2020 (for equities), June/July 2020 (for options), and additional sub-phases related to order and trade file submissions were implemented through December 2021. The final implementation sub-phase, related to broker-dealer customer and account information submissions by Industry Members, is now scheduled to go live in July 2022 (or by a subsequent date in the event the current deadline is extended). While the funding of the CAT is ultimately expected to be provided by both the SROs/Plan Participants (which includes our U.S.-based securities exchanges) and Industry Members, until fee filings associated with the funding model are effective with or approved by the SEC, the funding to date has solely been provided by the SROs/Plan Participants. The funding by the SROs/Plan Participants has been done in exchange for promissory notes expected to be repaid once such Industry Member fees are collected. Until those fees are collected, the SROs/Plan Participants may continue to incur additional significant costs, including as a result of replacing the plan processor, or result in the uncollectibility of promissory notes related to the funding of the implementation and operation of the CAT. See Note 8 (“Credit Losses”) and Note 9 (“Other Assets, Net”) for further information. In addition, on February 14, 2021, Consolidated Audit Trail, LLC, formed by SRO Plan Participants to implement the CAT requirements, filed motions to stay all or portions of two exemptive orders the SEC issued on December 16, 2020 related to the implementation of the CAT. On February 16, 2021, Consolidated Audit Trail, LLC also petitioned the U.S. Court of Appeals for the District of Columbia Circuit (“D.C. Circuit”) for judicial review of the two exemptive orders, asserting that the orders are unlawful. On April 7, 2021, the D.C. Circuit ordered the case to remain in abeyance, directed the filing of status reports every 60 days and ordered the parties “to file motions to govern future proceedings within 30 days after the discussions between the parties and the agency proceedings are completed.” Intellectual Property We own or have rights to a number of intellectual property assets, including trademarks, service marks, domain names, trade names, copyrights, trade secrets and patents. While the majority of our intellectual property is protected under U.S. law, we have many intellectual property assets protected by laws in Europe, Asia and other parts of the world. We license some intellectual property assets to other entities. We attempt to protect our intellectual property rights, while respecting the legitimate intellectual property rights of others. Human Capital Management Cboe has a robust human capital management program in place focused on equal opportunities including diversity, equity and inclusion (“DEI”), performance and career development, health and well-being, comprehensive benefits, training, talent acquisition, and succession planning. Additional information on our approach to human capital and ESG issues can be found in the Cboe Global Markets, Inc. Environmental, Social and Governance Report located in the Corporate Social Responsibility section of our website at https://markets.cboe.com/about/corporate-social-responsibility, which does not form a part of this Form 10-K. 24 Table of Contents Equal Opportunity, Diversity, and Pay Equity Cboe believes in a culture of diversity and inclusion that promotes creativity, collaboration and innovation, which is critical to the success of our business and defining the markets of tomorrow. Cboe is an equal opportunity employer and provides equal employment opportunities to all qualified persons without regard to sex, race, color, ethnicity, creed, religion, national origin, ancestry, citizenship status, age, veteran or military status, disability, marital status, domestic partnership or civil union status, pregnancy, sexual orientation, genetic status, gender identity or expression, and any other characteristic protected by law (a “Protected Characteristic”). Cboe is committed to applying our Equal Employment Opportunity Policy to all employment practices that impact the terms and conditions of employment including, but not limited to, hiring, evaluation, discipline, promotion, training, compensation, transfer, and termination. Actively nurturing and maintaining a diverse and inclusive culture at Cboe is a core imperative. We believe that our collective and unique perspectives fuel our capabilities, enhance our team spirit and enable us to attract and retain top talent as we define the markets of the future. Our commitment and responsibility in this regard starts at the top, with leadership and support from the full Cboe Board of Directors and executive team. One of the most compelling examples of our pledge to equality, diversity and inclusion throughout our Company is the completion of our first pay equity study in 2019. In 2020, we finalized the implementation of the findings of our inaugural study. To maintain and strengthen our efforts in this area, we also review the critical touchpoints across the employee journey with Cboe to keep a level playing field, from the talent selection, promotion, leadership development and succession planning processes and make adjustments, as necessary, to ensure opportunity parity across the Company. Our goal is to ensure that equal pay and equal opportunity for all that results in a collaborative, high performing organization bringing new innovations to market and providing superior service to our customers. The Cboe Women’s Initiative works toward its mission: to increase representation, strengthen voices, and build a culture of opportunity and advancement for the women of Cboe. The Women’s Initiative is led by an associate board and engages women throughout the Company on a variety of programs. More specifically, the Women’s Initiative is comprised of three committees that target areas where its membership strives to promote change, such as networking events, building a formal mentorship program and an advocacy group aimed at gathering input on topics of importance for its membership. This outreach helps shape the planning and focus for the Initiative. Networking events include the “Trailblazers” events where senior women share their success stories through personal accounts of career growth and impact and speakers on Male Allyship in the workplace. In its first year, the mentorship program paired over 45 mentors with mentees across the Company. We are also proud to share that Cboe recently formed an employee Diversity Leadership Council in 2020 focused on unlocking the potential of a variety of perspectives, capabilities and cultural experiences. We believe in a culture of diversity and inclusion that promotes creativity, collaboration and innovation, which is critical to the success of our business and defining the markets of tomorrow. To reinforce this belief, this council is a collective voice on how Cboe strives to create a diverse workforce that reflects the world in which we operate. Further, they are charged with oversight on how we build an inclusive culture where every employee feels welcome, safe and empowered. In 2021, we also created a new DEI leadership position within our human resources organization to be accountable for helping to establish the strategy and execution of our DEI approach to attract develop and retain top diverse talent while fostering a community of belonging and inclusion. To reinforce our commitment to organizational wide education and commitment to diversity and inclusion we provided a full-day Unconscious Bias training through third-party experts for all managers around the globe in 2020 with the commitment to continue the rollout of this program for all employees. In addition, in 2021, we launched Cboe Empowers and Cboe’s Veterans Initiative. Cboe Empowers is a community engagement program that provides mentorship, scholarship and guidance to under-resourced students throughout their educational journey through access to Cboe's associates, resources, work environment and other learning and experience opportunities. Initially launched in Chicago, the vision for Cboe Empowers is to support students through all stages of education from elementary or primary school to career by providing mentorship, learning and experience opportunities, professional development and scholarships to students within the Chicago Public School system and graduates pursuing higher education. Cboe Empowers expects to supplement its own programs by collaborating with local partners, including the Greenwood Project and Working in the Schools, to help create maximum impact for its participants. The Cboe Veterans Initiative is an Associate Resource Group that operates based on four main pillars: recruiting, mentorship, service, and networking. The vision for the Cboe Veterans Initiative is to actively seek Veteran talent, provide mentorship to veterans within and outside of the Company, commit to giving back to the Veteran community through financial and non-monetary support, and encourage outreach to Cboe Veterans. 25 Table of Contents Performance and Career Development Cboe expects employees to perform their duties to the best of their ability and to develop their competencies for career growth. We recognize the need to provide ongoing, timely, and constructive performance feedback. Cboe has designed a Performance Management Program that drives the professional development of our employees while also providing fair and equitable rewards and recognition. The principles of performance management include: ● align performance expectations with strategy and goals of the business, ● ongoing open dialogue regarding performance and development, ● foster accountability for behaviors and actions which contribute to a positive culture, and ● commitment to deliver results which drive our business. To help promote employee career development, we started in 2021 and are planning to launch in 2022, SCOUT, which is an AI powered talent management tool that will help us deliver internal mobility and career development opportunities for our employees. Employee Health and Well-Being and Comprehensive Benefits Program Cboe’s vision is to support the overall wellness of employees and their families through education and activities that encourage a healthy lifestyle, resulting in improved health and productivity. Our programs and benefit plans provide a corporate atmosphere of collective well-being that incorporate strategies for physical, emotional, mental and financial wellness. Our programs focused on enhanced employee assistance programs, wellness programs and challenges, that include both mental and physical wellbeing, and webinars and classes through our retirement vendor to support the financial health of our employees. To further these efforts, we launched the CboeFit program that creates an opportunity to elevate these programs and strengthen employee engagement as we execute against our wellness vision and strategies. With the global pandemic in 2020 and 2021, there was further focus on our Employee Assistance program that was strengthened across the globe with a diverse set of mental health resources aimed at supporting our employees during a unique and challenging time. Employee Engagement and Pulse Surveys, Town Halls and an Open-Door Policy In 2021, Cboe conducted our fourth annual employee engagement survey and has implemented career, leadership, and culture focused programs in response to the survey findings. Our participation rate exceeds standard benchmarks and a significant majority of our employees would recommend Cboe as a great place to work. To further cement our commitment to Diversity and Inclusion, we added new, enhanced questions in this area. Our Diversity Leadership Council hosted a special focus group to review these specific results to listen to the voices of our diverse population, prioritize their feedback and ideas, and create commitments for actionable improvements. Our senior management team continues to hold the commitment to an open-door policy and encourages the free flow of information and communication in furtherance of active transparency. With the global pandemic, our ability to tap into the voice of our employees was critically important. We conducted regular pulse surveys to gauge sentiment in making critical decisions. Our CEO also issues weekly letters to help connect with our employees. Human Resources also provided ongoing regular resources and tips to help support the variety of challenges from the new reality of fully remote work to childcare and elder care that our employees faced throughout 2021. Cboe also continues to create an open and frank atmosphere in which any grievance, complaint, suggestion or question receives a timely response. Cboe offers a whistleblower hotline for complaints, which can be made anonymously. Additionally, employees can raise questions and suggestions to the Cboe Human Resources team either in-person or via a group email address and are either responded to individually or addressed at our Global Town Hall meetings. The objective of these town halls is to provide employees an update on Company news, share updates from major business lines, as well as provide a forum to ask questions and offer feedback. Town halls can include updates on anything from legislation that may impact our business to ESG topics. Employees are encouraged to participate in free 26 Table of Contents flow of information and communication and to offer positive and constructive feedback in furtherance of active transparency. To further reinforce our commitment to employee engagement as a result of changing work styles due to COVID-19, we began in late 2021 a future-of-work study with a third party to help determine where Cboe employees might be best suited to work from in the future, whether it is in the office, remotely, or a hybrid mix. Training and Succession Planning We believe that the development of all Cboe employees helps drive our collective success. Through skill and competency development we signal our investment in all while also enabling enhanced productivity. Through our tuition reimbursement program, our employees receive financial support in their pursuit of specialized university courses and degrees. In addition to our ongoing offering of online courses on diverse topics through our corporate university, CboeU, employees can participate in the CboeLearns hybrid program focused on virtual classroom instruction combined with work application and CboeLive, which is focused on business topics to foster organizational-wide knowledge sharing and education. Leadership is another critical element to our success at Cboe. People managers globally participated in a two-day training focused on the “4 Essential Roles of Leadership” (1. Inspire Trust; 2. Create Vision; 3. Execute Strategy; 4. Coach Potential). We expanded on our leadership training through the design and launch of a bespoke 8-week program, CboeLeads, expanding on the development of our high potential leaders further strengthening the leadership bench and accelerating readiness of this key talent pool. The senior management team participated in an additional one-day workshop focused on their roles that was also accompanied by Leadership toolkits to guide an enhanced approach to coaching and career conversations. Cboe has held several succession planning discussions with the Compensation Committee and Board of Directors to plan for the fulfillment of essential roles, such as the CEO and other senior officers. This process includes investments in advanced development planning for targeted successors to accelerate their readiness through key internal projects and assignments as well as tailored training. Diversity and inclusion are a formal part of Cboe's succession planning process as we work to identify and advance internal diverse talent and, in parallel, continually scan external talent pools for successors.

We hold exclusive licenses to list securities index options on the S&P 500 Index, the Russell 2000 Index, as well as others, granted to us by the owners of such indices, and additionally hold exclusive rights to our proprietary VIX methodology that provides the basis for VIX options and futures. In 2021, approximately 53.2% of our net transaction and clearing fees (defined below) were generated by futures and index options, the overwhelming majority of which were 30 Table of Contents generated by our exclusively-licensed products (e.g., SPX options) and products based on our proprietary VIX methodology (e.g., VIX options and futures). The bulk of this revenue is attributable to our SPX options and VIX options and futures. As a result, our revenues less cost of revenues are dependent in large part on the exclusive licenses we hold for these products and our ability to maintain our exclusive proprietary rights in the VIX methodology and related products and indices. There is a risk, with respect to each of our current exclusive licenses, that the owner of the index may not renew the license with us on an exclusive basis or at all. In the first event, we would be subject to multiple listing in the trading of what is now an index product traded by us on an exclusive basis, which could result in a loss of market share and negatively impact our profitability. In the second event, we could lose the right to list the index product entirely. The loss or limited use of any of our exclusive index licenses, especially for the S&P 500 Index, for any reason could have a material adverse effect on our business and profitability. In addition to the risks related to our exclusive licenses, if we are unable to retain exclusive proprietary rights in the VIX methodology and related products and indices, our volatility products could be subject to multiple listing which could have a material adverse effect on us. The EU has adopted legislation affecting providers and users of benchmark indices in the EU. MiFIR requires benchmarks used to value a financial instrument in the EU to be made available on a non-discriminatory basis to all EU trading venues and central counterparty clearinghouses for the purposes of trading and clearing. As a result, owners of such benchmarks must provide licenses on fair, reasonable and non-discriminatory terms. While similar legislation to MiFIR has not been proposed in the U.S., if it were passed, it could cause us to lose our exclusive rights to list and trade proprietary and licensed index products. Further, in 2018, the EU implemented the EU Benchmark Regulation, which regulates users, data providers and calculators of benchmarks (“administrators”) in the EU, and among other things, prohibits use of benchmarks provided by administrators outside the EU in connection with EU financial instrument unless the administrator is deemed to be subject to an EU equivalent regulatory regime and the benchmark is registered in an EU member state. These regulations and other emerging regulatory regimes around the world may impact international customers’ interest in or ability to trade index-based products listed on our U.S. exchanges, as well as impact our expansion into foreign trading of our index-based products and our ability to license proprietary indices for use outside of the U.S. Furthermore, our competitors may succeed in developing, offering and providing a market for the trading of index-based or volatility products that are economically similar to those that we offer and they may become successful and take away volume from our products. It is also possible that a third party may offer trading in index-based products that are the same as those that are the subject of one of our exclusive licenses, but in a jurisdiction in which the index owner cannot require a license or in a manner otherwise not limited by our exclusive license. The value of our licenses to exclusively list securities index options and futures also depends on the continued ability of index owners to require licenses for the trading of options and futures based on their indices. Although we and other index owners have prevailed in legal actions seeking to challenge our rights to exclusively license indices, we may be subject to changes in the law or other actions taken in the future that might impede our ability to exclusively offer trading in certain index options and futures. General economic conditions and other factors beyond our control could significantly reduce demand for our products and services and harm our business. The volume of trading and clearing transactions and the demand for our products and services are directly affected by economic, political and market conditions in the U.S., Europe and elsewhere in the world that are beyond our control, including: ● economic, political and included the financial results of Bats in our consolidated financial results from March 1, 2017. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​      2019      2018      2017      2016      2015 ​ ​ (in millions, except per share data) Consolidated Statements of Operations Data: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Transaction fees ​ $ 1,716.2 ​ $ 1,986.9 ​ $ 1,564.9 ​ $ 509.3 ​ $ 485.3 Access and capacity fees ​ ​ 221.9 ​ ​ 211.0 ​ ​ 181.6 ​ ​ 98.7 ​ ​ 95.5 Market data fees ​ ​ 213.5 ​ ​ 204.0 ​ ​ 164.5 ​ ​ 33.2 ​ ​ 30.0 Regulatory fees ​ ​ 311.7 ​ ​ 333.9 ​ ​ 291.5 ​ ​ 48.3 ​ ​ 33.5 Other revenue ​ ​ 32.8 ​ ​ 33.0 ​ ​ 26.6 ​ ​ 13.6 ​ ​ 19.5 Total revenues ​ ​ 2,496.1 ​ ​ 2,768.8 ​ ​ 2,229.1 ​ ​ 703.1 ​ ​ 663.8 Cost of revenues: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liquidity payments ​ ​ 964.7 ​ ​ 1,113.0 ​ ​ 849.7 ​ ​ 35.8 ​ ​ 29.2 Routing and clearing ​ ​ 35.8 ​ ​ 39.1 ​ ​ 37.6 ​ ​ 11.1 ​ ​ 2.3 Section 31 fees (1) ​ ​ 271.4 ​ ​ 302.4 ​ ​ 260.0 ​ ​ 11.8 ​ ​ — Royalty fees ​ ​ 86.8 ​ ​ 97.4 ​ ​ 86.2 ​ ​ 78.0 ​ ​ 70.6 Other ​ ​ 0.5 ​ ​ — ​ ​ — ​ ​ — ​ ​ — Total cost of revenues ​ ​ 1,359.2 ​ ​ 1,551.9 ​ ​ 1,233.5 ​ ​ 136.7 ​ ​ 102.1 Revenues less cost of revenues ​ ​ 1,136.9 ​ ​ 1,216.9 ​ ​ 995.6 ​ ​ 566.4 ​ ​ 561.7 Operating expenses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Compensation and benefits ​ ​ 199.0 ​ ​ 228.8 ​ ​ 201.4 ​ ​ 113.2 ​ ​ 105.9 Depreciation and amortization ​ ​ 176.6 ​ ​ 204.0 ​ ​ 192.2 ​ ​ 44.4 ​ ​ 46.3 Technology support services ​ ​ 46.2 ​ ​ 47.9 ​ ​ 42.1 ​ ​ 22.5 ​ ​ 20.7 Professional fees and outside services ​ ​ 68.3 ​ ​ 68.3 ​ ​ 66.0 ​ ​ 53.1 ​ ​ 50.1 Travel and promotional expenses ​ ​ 11.9 ​ ​ 13.0 ​ ​ 17.2 ​ ​ 11.0 ​ ​ 9.0 Facilities costs ​ ​ 11.0 ​ ​ 11.5 ​ ​ 10.3 ​ ​ 5.7 ​ ​ 5.0 Acquisition-related costs ​ ​ 48.5 ​ ​ 30.0 ​ ​ 84.4 ​ ​ 13.6 ​ ​ — Other expenses ​ ​ 38.2 ​ ​ 14.0 ​ ​ 10.1 ​ ​ 4.7 ​ ​ 4.8 Total operating expenses ​ ​ 599.7 ​ ​ 617.5 ​ ​ 623.7 ​ ​ 268.2 ​ ​ 241.8 Operating income ​ ​ 537.2 ​ ​ 599.4 ​ ​ 371.9 ​ ​ 298.2 ​ ​ 319.9 Non-operating (expenses) income: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest expense, net ​ ​ (35.9) ​ ​ (38.2) ​ ​ (41.3) ​ ​ (5.7) ​ ​ — Other income, net ​ ​ 0.1 ​ ​ 10.0 ​ ​ 3.8 ​ ​ 14.1 ​ ​ 4.1 Income before income tax provision ​ ​ 501.4 ​ ​ 571.2 ​ ​ 334.4 ​ ​ 306.6 ​ ​ 324.0 Income tax provision ​ ​ 130.6 ​ ​ 146.0 ​ ​ (66.2) ​ ​ 120.9 ​ ​ 119.0 Net income ​ $ 370.8 ​ $ 425.2 ​ $ 400.6 ​ $ 185.7 ​ $ 205.0 Net loss attributable to noncontrolling interest ​ ​ 4.1 ​ ​ 1.3 ​ ​ 1.1 ​ ​ 1.1 ​ ​ — Net income excluding noncontrolling interest ​ ​ 374.9 ​ ​ 426.5 ​ ​ 401.7 ​ ​ 186.8 ​ ​ 205.0 Change in redemption value of noncontrolling interest ​ ​ (0.5) ​ ​ (1.3) ​ ​ (1.1) ​ ​ (1.1) ​ ​ — Net income allocated to participating securities ​ ​ (1.7) ​ ​ (3.1) ​ ​ (3.9) ​ ​ (0.8) ​ ​ (0.9) Net income allocated to common stockholders ​ $ 372.7 ​ $ 422.1 ​ $ 396.7 ​ $ 184.9 ​ $ 204.1 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic earnings per share ​ $ 3.35 ​ $ 3.78 ​ $ 3.70 ​ $ 2.27 ​ $ 2.46 Diluted earnings per share ​ $ 3.34 ​ $ 3.76 ​ $ 3.69 ​ $ 2.27 ​ $ 2.46 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic weighted average shares outstanding ​ ​ 111.4 ​ ​ 111.8 ​ ​ 107.2 ​ ​ 81.4 ​ ​ 83.1 Diluted weighted average shares outstanding ​ ​ 111.8 ​ ​ 112.2 ​ ​ 107.5 ​ ​ 81.4 ​ ​ 83.1 Distributions per share ​ $ 1.34 ​ $ 1.16 ​ $ 1.04 ​ $ 0.96 ​ $ 0.88 (1) As national securities exchanges, Cboe Options, C2, BZX, BYX, EDGX, and EDGA are assessed fees pursuant to Section 31 of the Exchange Act.

Any of these factors, individually or collectively, could have a material adverse effect on our business, financial condition and operating results by causing a substantial decline in the financial services markets and reducing trading and clearing volumes and demand for market data. Our business may be adversely affected by price competition. The securities industry is characterized by intense price competition, especially with respect to transaction fees. We may be required to adjust pricing to respond to actions by new or existing competitors, which could adversely impact our business, financial condition and operating results. We also compete with respect to the pricing of market data and value-added market data, such as historical market data. In our options segment, the pricing model for trade execution has changed in response to competitive market conditions, and our competitors have adjusted transaction fees and fee structures accordingly, including by opening new exchanges, which allow them to offer multiple pricing models that can appeal to different segments of market participants. These changes have resulted in significant pricing pressures on us, especially on transaction fees and incentives for multi-listed products. As a result of these pricing pressures, our average rate per multi-listed options contract may decrease. It is likely that this pressure will continue and even intensify as our competitors continue to seek to increase their share of trading by further reducing their transaction fees or by offering other financial incentives to order providers and liquidity providers to induce them to direct orders to their markets. In addition, one or more competitors may engage in aggressive pricing strategies and significantly decrease or completely eliminate their profit margin for a period of time in order to capture a greater share of trading volume. Some order-providing firms on our exchanges have taken ownership positions in options exchanges that compete with us and such exchanges have given those firms added economic incentives to direct orders to them. With respect to our proprietary products, we compete with futures exchanges and swap execution facilities that offer similar products and other financial market participants that offer over-the-counter derivatives. We also compete against certain multi-listed options products, such as SPY, which offer some of the features of our proprietary products, such as SPX. To attract market share, we may offer “inverted” pricing specials or no-transaction fee trading from time to time, per various fee schedules across our equities exchanges. These forms of promotions, along with other supplemental liquidity programs, may adversely affect our profitability. Further, regulatory and legal developments could also impact our ability to adjust pricing to respond to actions by new or existing competitors. In the U.S., we are generally required to file with the SEC any changes to the fees that we charge and in recent years the SEC has more heavily scrutinized pricing changes. If we are unable to compete successfully with respect to the pricing of our services and products, our business, financial condition and operating results may be materially and adversely affected. We could lose a substantial percentage of our share of trading if we are unable to price transactions in a competitive manner. Also, our profits could decline if competitive pressures or regulatory changes force us to reduce fees. 32 Table of Contents A significant portion of our operating revenues is generated by our transaction and clearing-based business. If the amount of trading volume on our markets or clearing volume decreases, or the product mix shifts to lower revenue products, our revenues from transaction and clearing fees will most likely decrease. In 2021, approximately 64.7% of our revenues less cost of revenues were generated by our transaction and clearing-based business. This business is dependent on our ability to attract and maintain order flow, both in absolute terms and relative to other market centers. If the amount of trading volume on our Exchanges, CFE, BIDS Trading, and MATCHNow, notional value traded on Cboe FX, Cboe SEF, Cboe Europe Equities and Derivatives, Cboe Australia, and Cboe Japan or clearing volumes at EuroCCP decreases, we are likely to see a decrease in fees. Our total trading or clearing volumes could decline if our market participants reduce their trading or clearing activity for any reason, such as: ● heightened capital requirements; ● transaction tax; ● regulatory or legislative actions; ● reduced need to trade due to changes in volatility and/or passive investment trends; ● reduced access to capital required to fund trading activities; ● consolidation among market participants; ● suspensions of open outcry trading; or ● significant market disruptions. Over the past few years, a number of legislative actions have been taken, both domestically and internationally, that may cause market participants to be subject to increased capital requirements and additional compliance burdens. These actions, including the Collins Amendment to Dodd-Frank, MiFID II and MiFIR, may cause market participants to reduce trading activity on our markets. In addition, the transaction fees generated are different based on type of product and other factors, including the type of customer and certain volume discounts. If the amount of our trading volume decreases, the mix traded shifts to our lower revenue per contract products, our revenues from transaction fees will most likely decrease. We can offer no assurance that we would be able to reduce our costs to match the amount of any such decrease. Revenues from our market data fees and access and capacity fees may be reduced due to declines in our market share, trading volumes or regulatory changes. The occurrence of any event that reduces the amount of market data fees that we receive, whether as a result of fee reductions, fewer members subscribing to the U.S. tape plans or other market data offerings, declines in market share, trading volumes, or notional volumes, or regulatory changes may have a direct negative impact on our business, financial condition, and operating results. For example, if our market share of U.S. listed equities and options or Cboe’s European equities trading volume were to decline, our share of market data fees could also decline. Moreover, market data fees could decline as a result of a reduction in the number of market data users, for example because of consolidation among market data subscribers or due to a decline in professional subscriptions as a result of staff reductions in the financial services industry or otherwise. Regulatory and legal developments could also impact the fees we receive from market data and access and capacity, or our cost in providing such services. In the U.S., we are generally required to file with the SEC any changes to the fees that we charge for our securities market data products and access and capacity fees. In recent years, certain industry groups have objected to the ability of exchanges to charge for certain market data products. In addition, the SEC and some media have scrutinized market data and market access. As discussed above, the implementation of the new Market Data Infrastructure rules could cause Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or to challenge the new rules, which may have a material impact on our business, financial condition, and operating results, including if, for example, there are lower SIP plan revenues or we must reduce the fees we charge for market data. See “Legal Proceedings” for more information. In addition, as discussed above, the SEC approved a Consolidated Data Plan to replace the three equity data plans that govern the dissemination of real-time, consolidated market data for NMS stocks. Such plan is being challenged, but if such Consolidated Data Plan were to be implemented, it may have a negative impact on the applicable market data revenues that we receive that are generated from such new plan. See “Legal Proceedings” for more information. 33 Table of Contents We believe Cboe Europe Equities and Derivatives currently offers market data to customers on a non-discriminatory basis at a reasonable cost. As European regulators determine how market data should be disaggregated and what is a reasonable commercial basis for providing market data, it could affect our ability to offer market data products in the same manner that we do today thereby causing an adverse effect on our European market data revenues. While MiFID II and MiFIR aim to encourage a commercial solution to a consolidated tape in Europe, should this fail to materialize, policy makers might be encouraged to implement a mandatory solution that could impact our ability to develop our own commercial offering. As discussed above, the E.C. published provisions for a consolidated tape for the EU, which is expected to be implemented in late 2023 or early 2024. As proposed, these provisions may have a material impact on our business, financial condition and operating results if, for example, we must reduce the fees we charge for market data. The technology upon which we rely, including those of our service providers, may be vulnerable to security risks, cybersecurity risks, insider threats, unauthorized disclosure of confidential information, operational disruptions, and other risks and events that could harm our business. The secure and reliable operation of our technology, including our computer systems and communications networks, and those of our service providers, market participants and other third-parties, is a critical element of our operations. These systems and networks may be subject to various cybersecurity incidents, improper or inadvertent access to or disclosure of confidential, commercially sensitive, or personally identifiable information, data theft, corruption or destruction, cyber-attack, ransomware, supply chain attack, denial of service attack, malware and other security problems, as well as acts of terrorism, attacks by threat actors including criminal groups, political activist groups and nation-state actors, attacks in connection with geopolitical activity such as the recent escalating tensions along the Russia-Ukraine border, natural disasters, human error, criminal insider activity, employee error, power loss, service provider, market participant or third-party disruptions or security breaches and other events that are beyond our control. Our increased adoption of remote working, initially driven by the COVID-19 pandemic, usage of mobile and cloud-based technologies and amount of newly acquired companies and related integrations may increase our risk for a cybersecurity incident. Moreover, given our position in the global financial services industry and as critical infrastructure, we may be more likely than other companies to be a direct target, or an indirect casualty, of such events. While we have experienced in the past, and we expect to continue to experience, cybersecurity threats and events of varying degrees, we are not aware of any of these threats or events having a material impact on our business, financial condition or operating results to date, however we cannot assure you that we will not experience future threats or events that may be material. We currently maintain policies, procedures and controls designed to reasonably protect the confidentiality, integrity, availability and reliability of our systems, networks and information more broadly, and to guard against cybersecurity incidents and unauthorized access. These policies, procedures and controls are subject to periodic monitoring, auditing, and evaluation practices, pursuant to our enterprise risk management program, which is supported by a three lines of defense approach, and our other governance practices. Further, we developed and maintain cybersecurity and data privacy training programs for our employees and our third-party consultants who have access to our systems, which includes simulations, tabletop exercises, and response readiness tests. Independent third-party cybersecurity penetration assessments are also routinely performed. Collectively, these safeguards and measures or those of our third-party providers, including any cloud technologies, may prove inadequate to prevent the attendant risk posed by cybersecurity incidents, subjecting us to contractual restrictions, liability and damages, loss of business, penalties, unfavorable publicity, and increased scrutiny by our regulators, and materially impacting our business, financial condition and operating results. We may be required to expend significant resources in the event of any real or threatened breaches in security or system failures, including to protect against threatened breaches, to alleviate harm caused by an actual breach, and to address any reputational harm or litigation or regulatory liability. Despite our cybersecurity measures, it is possible for security vulnerabilities or breaches to remain undetected for an extended period of time. Such harms also could cause us to lose market participants, experience lower trading volume, and negatively impact our competitive advantage and business, financial condition and operating results.    Additionally, as threats continue to evolve and increase, and as the domestic and international regulatory environment related to information security, data collection and use, and privacy becomes increasingly rigorous, we may be required to devote significant additional resources to modify and enhance our security controls and to identify and remediate any security vulnerabilities, which could have an adverse effect on our business, financial condition and operating results. If we fail to attract or retain highly skilled management and other employees our business may be harmed. Our success largely depends on the skills, experience and continued efforts of management and other key personnel. As a result, to be successful, we must retain and motivate executives and other key employees. However, we have no assurances that these employees will remain with us. The roles and responsibilities of departing executive 34 Table of Contents officers and employees will need to be filled either by existing or new officers and employees, which may require us to devote time and resources to identifying, hiring and integrating replacements for the departed executives and employees that could otherwise be used to pursue business opportunities, which could have a material adverse effect on our overall business, financial condition and operating results. There is substantial competition for qualified and capable personnel in the technology space, which may make it difficult for us to retain and recruit qualified employees in sufficient numbers. This competition has become exacerbated by the increase in employee resignations currently taking place throughout the United States as a result of the COVID-19 pandemic, which is commonly referred to as the “great resignation,” as well as the growth of new asset classes such as the digital asset space. During this great resignation, we have faced increased challenges in retaining and attracting qualified employees. If we fail to retain our current employees, it would be difficult and costly to identify, recruit and train replacements needed to continue to conduct and expand our business. In particular, failure to retain and attract qualified technology personnel could result in systems failures. Consequently, our reputation may be harmed, we may incur additional costs and our profitability could decline. There can be no assurance that we will be able to retain and motivate our employees in the same manner as wehave historically done. Additionally, effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving our management team and key employees could hinder our strategic planning and execution. Intense competition could materially adversely affect our market share and financial performance. The market for trade execution services, clearing and products is intensely competitive in the asset classes and geographies in which we operate. Increased competition may result in a decline in our share of trading activity and a decline in our revenues from transaction and clearing fees and market data fees, thereby materially adversely affecting our operating results. We compete with a number of entities on several different fronts, including the cost, quality and speed of our trade execution, functionality and ease of use of our trading and clearing platforms, range of our products and services, our technological innovation and adaptation and our reputation. In particular, we have seen increased competition from off-exchange venues, which have increased their share of trading activity. See “Business – Competition” for more information. Some of our competitors and potential competitors have greater financial, marketing, technological, personnel and other resources than we do. These factors may enable them to develop similar or more innovative products, to offer lower transaction and clearing fees or better execution to their customers or to execute their business strategies more quickly or efficiently than we can. In addition, our business, financial condition and operating results may be materially adversely affected if we cannot successfully develop, introduce and/or market new services and products or if we need to adopt costly and customized technology for our services and products. Furthermore, new or existing competitors may: ● respond more quickly to competitive pressures; ● develop products that compete with our products or are preferred by our customers; ● offer products and services at prices below ours to gain market share and to promote other businesses; ● develop and expand their technology and service offerings more efficiently; ● provide better, more user-friendly and more reliable technology; ● take greater advantage of acquisitions, alliances and other opportunities; ● market, promote, bundle and sell their products and services more effectively; ● leverage existing relationships with customers and alliance partners more effectively or exploit brand names to market and sell their services; and ● exploit regulatory disparities between traditional, regulated exchanges and alternative markets, including over-the-counter markets, that benefit from a reduced regulatory burden and lower-cost business model. If our products, markets, services and technology are not competitive or we fail to anticipate or respond adequately to changes in technology, customer preferences and regulatory requirements or any significant delays in product development efforts our business, financial condition and operating results could be materially harmed. 35 Table of Contents We depend on third-party service providers for certain services that are important to our business. An interruption, significant increase in fees or cessation or impairment of such service by any third party could have a material adverse effect on our business, financial condition and operating results. We depend on a number of service providers, including clearing organizations such as OCC, NSCC, DTC, CDS, LCH, EuroCCP, our wholly-owned subsidiary, JSCC, ASX Clear Pty Ltd, and SIX x-clear; securities information processors such as the CTA, UTP Securities Information Processor and OPRA; regulatory and other service providers such as FINRA and OCC; the hosts of our data and disaster recovery centers; and various vendors of communications and networking products and services. In addition, we also depend on third party routing and clearing firms that are involved in processing transactions on our behalf. More specifically: ● If OCC, NSCC, DTC, CDS, LCH, EuroCCP, JSCC, ASX Clear Pty Ltd, and SIX x-clear were unable to perform clearing services for existing or new products, or their clearing members were unable or unwilling to clear through them, transactions could likely not occur on our markets or there may be delays, including until clearing is moved to another clearing agency. In 2021, approximately 53.2% of our net transaction and clearing fees were generated by options and futures that were cleared through OCC. ● OPRA, UTP Securities Information Processor and the CTA consolidate options and equities market information, respectively, such as last sale reports and quotations. If any of them were unable to provide this information for a sustained period of time, we may be unable to offer trading on our options and equities markets. ● We are heavily dependent on technology for our markets, including our data and disaster recovery centers, some of which are housed by third parties, and certain communications and networking products and services. If this technology is unavailable, and cannot be replaced in a sufficiently short time period, we may be unable to operate our markets. ● We utilize a third-party cloud service provider to maintain secondary offsite backups of our and our customers’ data and to distribute real-time data, and we may utilize third-party cloud service providers in the future for additional services. We do not control the operations of third-party cloud service providers or their facilities and may be vulnerable to disruptions in our access to the platform as a result of a number of potential causes, including technical failure, natural disasters, fraud or security attacks that we cannot predict or prevent. Additionally, any vulnerability of third-party cloud service providers could expose our or our customers’ confidential data, which could result in harm to our business reputation. ● FINRA and OCC provide certain regulatory services and functions for our options, equities and futures exchanges, while we retain regulatory responsibilities for such services. If FINRA or OCC stopped providing services, or provided inadequate services, we may be subject to action by the SEC or CFTC, or may have limitations placed upon our markets. ● We rely on FINRA CAT LLC, a subsidiary of FINRA, to provide services for the implementation of the CAT. If FINRA CAT LLC stops providing services or provides inadequate services, we and the other execution venues may incur regulatory liability including enforcement action by the SEC or limitations placed upon our markets. In addition, until the SEC approves a funding model that shares the cost of the CAT between the SROs and industry members, the SROs may continue to incur additional significant costs, including as a result of replacing the plan processor, or result in not being able to collect on the promissory notes related to the funding of the implementation and operation of the CAT. ● We rely on third party routing and clearing firms to clear trades in U.S. listed equity securities routed by us to other markets, and to execute trades in options that we route to other markets.  With respect to options, all contracts traded on our exchanges must be cleared through clearing members of OCC. At December 31, 2021, there were 97 TPHs that are clearing members of OCC. Two clearing members accounted for approximately 61.5% of transaction and other fees collected through OCC in 2021. The next largest clearing member accounted for approximately 23.5% of transaction and other fees collected through OCC. Additionally, the two largest clearing members clear the majority of the market-maker sides of transactions at Cboe Options, C2, BZX, EDGX and at all of the options exchanges. Should one of these clearing members or liquidity providers exit the business or withdraw from our options exchanges, impose additional market-maker financial requirements or if market-makers were unable to transfer to another clearing member or other liquidity providers were unable to provide additional liquidity, this could create a significant disruption to the options markets, including ours. We cannot provide assurance that any of these providers will be able to continue to provide these services in an efficient manner or that they will be able to adequately expand their services to meet our needs. An interruption or malfunction in or the cessation or impairment of an important service by a third party or disruption of a third party’s operations could cause us to halt trading in some or all of our products or our services, make us unable to conduct other aspects of our business, cause us to experience the loss of a significant number of market participants or cause us to 36 Table of Contents experience a significant reduction in trading activity on our options and futures markets, each of which could have a material adverse effect on our business, financial condition and operating results. In addition, our inability to make alternative arrangements, such as moving clearing to another clearing agency, in a timely manner, or at all, could have a material adverse impact on our business, financial condition and operating results. If an index provider from which we have a license or a service provider with respect to proprietary products fails to maintain the quality and integrity of their indices or fails to perform under our agreements with them, if we fail to maintain the quality and integrity of our proprietary indices or indices and other values that we calculate as an index provider, or if customer preferences change, the revenues that are generated from the trading of proprietary products or the calculation and dissemination of index values may suffer. We are a party to a number of license agreements that permit us to list tradeable products related to various indices that are among the most actively traded products on our exchanges. We also enter into agreements pursuant to which we act as an index provider and calculate and disseminate proprietary indices and other values. We believe that demand for our products is based in part on market perception of the quality and integrity of these indices. The quality and integrity of these indices are dependent on the ability of index providers, including us, to maintain the index. Maintenance includes ongoing index calculation, index rebalancing and dependance on index providers for a number of things, including the provision of index data. We also rely on index providers to enforce intellectual property rights against unlicensed uses of the indices and uses of the indices that infringe on our licenses. Some of our agreements concerning our proprietary products obligate the parties to those agreements to provide important services to us. If any of our index providers, including us, are unable to maintain the quality and integrity of indices, or if any of the index providers or service providers, including us, fail to perform their obligations under the agreements, trading in these products, and therefore transaction fees we receive, may be materially adversely affected or we may not receive the financial benefits of the agreements that we negotiated. Differences in the calculations from methodologies described in published materials or incorrect calculations of spot VIX Index values or our other spot volatility indices, including those instances that we announced on July 30, 2021, or the failure to implement any planned remedial changes may result in the loss of perceived quality and integrity of our indices, loss of demand for our products, increased potential for investigations and enforcement proceedings, increased potential for failure to perform our obligations under agreements concerning our products or in our capacity as an index provider, and increased exposure to third party claims and related litigation expenses, which could have a material adverse effect on our business, financial condition and operating results. The COVID-19 pandemic and its effects have had significant impacts on economies around the world. Further impacts of the COVID-19 pandemic could have a material adverse effect on our business, financial condition, operating results and cash flows. The COVID-19 pandemic has had significant impacts on economies around the world. Governments, public institutions, and other organizations around the world have taken, and may take additional or reimpose previous, emergency measures to combat COVID-19’s spread, including vaccination requirements, implementation of travel bans, stay-at-home orders, border closures, and closures of offices, factories, schools, public buildings and businesses. These measures may disrupt the supply chain and may interfere with the ability of our employees, vendors, technology equipment suppliers, data and disaster recovery centers, and other service providers to perform their respective responsibilities and obligations relative to the conduct of our business. In addition to uncertain expenses and impacts to our business we may incur due to COVID-19 as part of us providing a safe and healthy work and trading environment, employees working remotely from different locations and in connection with our return to our offices, we may also be subject to claims from employees or customers alleging failure to maintain safe premises and restrictions with respect to protocols relating to COVID-19. Further, changes in trading behavior, impacts to trading behavior due to market disruptions, additional temporary suspensions of open outcry trading, temporary regulatory measures and other future developments caused by the effects of COVID-19, including a re-occurrence of cases and the emergence of variants, could impact trading volumes and the demand for our products, market data and services, which could have a material adverse effect on our business, financial condition, operating results and cash flows and could heighten many of the other risks described herein. Our operations outside of the U.S. expose us to currency risk. In addition to our operations in the U.S., we have operations in the UK, continental Europe, Canada, Hong Kong, Australia, Japan, Philippines, and Singapore. We, therefore, have exposure to exchange rate movements between the British pound, the Euro, the Canadian dollar, the Hong Kong dollar, the Australian dollar, the Japanese Yen, the 37 Table of Contents Philippine Peso, and the Singapore dollar against the U.S. dollar. Significant inflation or changes in foreign exchange rates with respect to one or more of these currencies could occur as a result of general economic or political conditions, acts of war or terrorism, changes in governmental monetary or tax policy, or changes in local interest rates. These exchange rate differences would affect the translation of our non-U.S. results of operations and financial condition into U.S. dollars as part of our consolidated financial statements. We and our licensors may not be able to protect our respective intellectual property rights. We rely on patent, trade secret, copyright and trademark laws, the law of the doctrine of misappropriation and contractual provisions to protect our proprietary technology, proprietary products, index methodologies and other proprietary rights. In addition, we rely on the intellectual property rights of our licensors in connection with our listing of exclusively-licensed index options and futures products. We and our licensors may not be able to prevent third parties from copying, or otherwise obtaining and using, our intellectual property without authorization, listing our proprietary or exclusively-licensed index products without licenses or otherwise infringing on our rights. We and our licensors may have to rely on litigation to enforce our intellectual property rights, determine the validity and scope of the proprietary rights of others or defend against claims of infringement or invalidity. We and our licensors may not be successful in this regard. Such litigation, whether successful or unsuccessful, could result in substantial costs to us, diversion of our resources or a reduction in our revenues, any of which could materially adversely affect our business. Our clearinghouse operations expose us to associated risks, including credit, liquidity, market and other risks related to the defaults of clearing participants and other counterparties. ​ We are subject to risks related to operating our clearinghouse, EuroCCP, including the risks of failing to meet strict business continuity requirements and regulatory oversight, risks of default by clearing participants and counterparties, due to bankruptcy, lack of liquidity, operational failure or other reasons, and the risks associated with the adequacy of participants’ margin and default funds. These risks could subject our business to substantial losses, reputational harm, regulatory consequences, including litigation, fines and enforcement actions, and the inability to operate our business, including the continued development of the European derivatives buildout. ​ To mitigate the credit risks related to defaults of clearing participants and other counterparties, including the market risk that we would only be able to close out a defaulting participant’s positions at a loss, there are minimum participation criteria to become a clearing participant and clearing participants are required to provide collateral to cover the margin requirement and default fund contributions. No guarantee can be given that the collateral provided will at all times be sufficient or provide absolute assurance against us experiencing financial losses from defaults by the participants or counterparties on their obligations. In addition, although such collateral is preferably held in European central banks and central securities depositories, there are occasions where commercial banks are used, which can expose us to risk of default by those banks. In addition, EuroCCP entered into a €1.5 billion committed syndicated multicurrency revolving and swingline credit facility that is available to be drawn by EuroCCP towards (a) financing unsettled amounts in connection with the settlement of transactions in securities and other items processed through EuroCCP’s clearing system and (b) financing any other liability or liquidity requirement of EuroCCP incurred in the operation of its clearing system, however we can give no assurance that this facility will be sufficient to meet all such obligations or sufficiently mitigate EuroCCP’s liquidity risk to meet its payment obligations when due. Substantial amounts of the collateral, and any amounts drawn under this facility, may be at risk if a clearing participant defaults on its obligations to our clearinghouse and its margin and default fund deposits are insufficient to meet its obligations. This facility is expected to terminate on June 30, 2022 and we may not be able to enter into a replacement facility on commercially reasonable terms, or at all. We cannot assure you that the mitigating measures, policies, safeguards and risk management procedures will be sufficient to detect problems or to protect us from a default or that we will not be materially and adversely affected in the event of a significant default. Computer and communications systems failures and capacity constraints could harm our reputation and our business. Our business depends on the integrity and performance of our computer and communications systems. If our systems cannot expand to cope with increased demand or otherwise fail to perform, we could experience unanticipated disruptions in service, slower response times and delays in the introduction of new products and services. These consequences could result in trading outages, lower trading and clearing volumes, financial losses, decreased customer service and satisfaction and regulatory sanctions and could have a material adverse effect on our ability to conduct our business. Although we have a back-up plan with respect to our significant trading and key corporate systems, the back-up systems or disaster recovery plans may prove to be inadequate in the event of a systems failure or cyber-security breach. Despite having disaster recovery facilities, there can be no guarantees that we will be able to open an efficient, transparent and liquid marketplace, if we can open at all, following a systems failure. Moreover, with extended trading 38 Table of Contents hours, we have to operate our systems longer and have fewer non-trading hours to address any potential concerns with the systems on which we rely. Our markets and clearinghouse have experienced occasional systems failures and delays in the past and in the future our systems may fail, in whole or in part, or may operate slowly, causing one or more of the following: ● unanticipated disruption in service to our participants; ● failures or delays during peak trading times or times of unusual market volatility; ● slower response times and delays in trade execution, clearing and processing; ● incomplete or inaccurate accounting, recording, clearing or processing of trades; and ● distribution of inaccurate or untimely market data to participants who rely on this data in their trading activity. Any of these events may cause: ● a loss in transaction, clearing or other fees due to the inability to provide services for a time; ● requests by market participants or others that we reimburse them for financial loss, either within the constraints of the limited liability provisions of our exchanges’ rules or in excess of those amounts; ● trading and clearing volumes to diminish on our markets and clearinghouse due to dissatisfaction with the platforms; and ● one or more of our regulators to investigate or take enforcement action against us. As a consequence of any of these events, our business, financial condition and results of operations could suffer materially. In addition to other measures, we test our systems to confirm whether they will be able to handle anticipated present and future peak trading and clearing activity or times of unusual market volatility. However, we cannot assure you that our estimates of future trading or clearing volume will be accurate or that our systems will always be able to accommodate actual trading or clearing volume without failure or degradation of performance. We anticipate that we will need to continue to make significant investments in hardware, software and telecommunications infrastructure to accommodate the increases in traffic. If we cannot increase the capacity and capabilities of our systems to accommodate increasing trading or clearing activity and to execute our business strategy, our ability to maintain or expand our businesses would be materially adversely affected. Our use of open source software code may subject our software to general release or require us to re-engineer our software, which could harm our business. Our technology platform uses open source software code. Companies that incorporate open source software into their products have, from time to time, faced claims challenging the ownership of open source software. As a result, we could be subject to suits by parties claiming ownership of what we believe to be open source software. In addition, some open source software licenses require users who distribute open source software as part of their software to publicly disclose all or part of the source code in their software and make any derivative works of the open source code available on unfavorable terms or at no cost. Open source license terms may be ambiguous, and many of the risks associated with usage of open source software cannot be eliminated. We believe that our use of open source software is in compliance with the relevant open source software licenses and does not require disclosure of any of our source code. However, if we were found to have inappropriately used open source software, we may be required to release our proprietary source code, re-engineer or discontinue use of our software or take other remedial action any or all of which could cause disruptions in, or impose significant costs on, our business. Damage to our reputation could have a material adverse effect on our business, financial condition and operating results. We believe one of our competitive strengths is our strong industry reputation. Various issues may give rise to reputational risk, including issues relating to: ● the representation of our business in the media; ● the quality and benefits of using our proprietary products, including the reliability, integrity and functionality of our transaction-based business and index calculations and the accuracy of our market data; 39 Table of Contents ● the ability to execute our business plan, key initiatives or new business ventures and the ability to keep up with changing customer demands and regulatory initiatives; ● our regulatory compliance and our enforcement of compliance on our customers; ● the accuracy of our financial statements and other financial and statistical information; ● the quality of our corporate governance structure; ● the quality of our disclosure controls and internal controls over financial reporting, including any failures in supervision; ● the integrity and performance of our computer and communications systems; ● the ability to successfully complete technology migrations; ● the failure to successfully expand into new asset classes, such as the digital asset space or U.S. Treasuries, or new geographies; ● security breaches, including any unauthorized delivery of proprietary data to third parties; ● management of our outsourcing relationships, including our relationship with FINRA and NFA; ● any misconduct or fraudulent activity by our employees, especially senior management, or other persons formerly or currently associated with us; ● our listings business and our enforcement of our listing rules; and ● any negative publicity surrounding the ETPs that we serve as the listing destination. Damage to our reputation could cause a reduction in the trading volume of our proprietary products or on our markets or cause us to lose customers. This, in turn, may have a material adverse effect on our business, financial condition and operating results. Financial or other problems experienced by third parties could have an adverse effect on our business. We are exposed to credit risk from third parties, including customers, clearing agents and counterparties. For example, we are exposed to credit risk for transaction fees we bill to customers on a monthly basis in arrears. Our customers and other third parties may default on their obligations to us due to a lack of liquidity, operational failure, bankruptcy or other reasons. For additional credit risks related to our clearinghouse operations, see the Risk Factor “Our clearinghouse operations expose us to associated risks, including credit, liquidity, market and other risks related to the defaults of clearing participants and other counterparties.” In addition, with respect to orders Cboe Trading routes to other markets for execution on behalf of our customers, Cboe Trading is exposed to counterparty credit risk in the case of failure to perform on the part of our routing and clearing firms that are involved in processing equities and options transactions on our behalf, as well as failure on the part of such brokers to pass back any transactional rebates. Wedbush and Morgan Stanley guarantee equity trades until one day after the trade date, after which time NSCC provides a guarantee. Thus, Cboe Trading is potentially exposed to credit risk to the counterparty to an equity trade routed to another market center between the trade date and one day after the trade date in the event that Wedbush or Morgan Stanley fails to perform. Additionally, BIDS Trading has counterparty credit risk exposure to BOA related to clearing until the day following the trade date, after which time NSCC provides a guarantee. With respect to U.S. listed equity options and futures, we deliver matched trades of our customers to the OCC, which acts as a central counterparty on all transactions occurring on Cboe Options, C2, BZX, EDGX, and CFE and, as such, guarantees clearance and settlement of all of our matched options and futures trades. With respect to Canadian equities, we deliver reports of matched trades of our customers to CDS, which acts as a central counterparty on all transactions occurring on MATCHNow and, as such, guarantees clearance and settlement of all of our matched Canadian equities trades. With respect to Australian equities and derivatives, we deliver matched trades of our customers to ASX Clear Pty Ltd and ASX Settlement Pty Ltd. ASX Clear Pty Ltd acts as a central counterparty on all transactions occurring on Cboe Australia and, as such, guarantees clearance and settlement on all of our matched trades in Australia. With respect to Japanese equities, we deliver matched trades of our customers to the JSCC, which acts as a central counterparty on all transactions occurring on Cboe Japan and, as such, guarantees clearance and settlement on all of our matched trades in Japan. With respect to routed U.S. equity transactions, Cboe Trading has counterparty credit risk exposure to Wedbush and Morgan Stanley related to clearing until the day following the trade date. Cboe Trading uses Wedbush to clear trades routed through affiliates of Credit Suisse Securities (USA) LLC as well as for trades routed directly to other exchanges and optionally dark pools. Morgan Stanley clears trades routed through the Morgan Stanley routing brokers and also clears executions routed to most dark pools. Cboe Trading maintains counterparty credit risk exposure from routing brokers with respect to rebates earned until completion of the routing brokers next invoice cycle following the execution. 40 Table of Contents With respect to U.S. listed equity and exchange traded product options, Cboe Trading is subject to counterparty credit risk exposure with respect to rebates earned from routing brokers until completion of the routing brokers’ next invoice cycle has completed for an execution. Our exposure to credit risk may be further impacted by volatile securities markets that may affect the ability of our customers, counterparties and other third parties to satisfy their obligations to us. Moreover, we may not be successful in managing our credit risk through mitigating measures, policies, safeguards and risk management procedures, reporting and control procedures or by maintaining credit standards. Any losses arising from such defaults or other credit losses could materially adversely affect our financial condition and operating results. While neither Cboe FX nor Cboe SEF has direct counterparty risk, Cboe FX or Cboe SEF may suffer a decrease in transaction volume if a bank or prime broker experiences an event that causes other prime brokers to decrease or revoke the credit available to the prime broker experiencing the event. Therefore, Cboe FX and Cboe SEF may have risk that is related to the credit of the banks and prime brokers that trade spot FX on the Cboe FX platform, or NDFs on Cboe SEF. We may be required to assume ownership of a position in securities in connection with our order routing service, which could subject us to trading losses when our broker-dealer disposes of that position. We offer a smart-order routing service through our broker-dealer subsidiary, Cboe Trading, which provides its customers with access to other market centers when we route their orders to those market centers for execution. In connection with this service, we may assume ownership of a position in securities. This may occur, for example, when a market center to which we have routed a customer’s order experiences systemic issues and is unable to determine the status of that order. When this happens, we may make a business decision to provide a cancellation notice to our customer, relieving our customer of any liability with respect to the order. We may be informed later, however, that the order was executed at the market center to which we routed it, in which case Cboe Trading would be required to take ownership of that securities position. Our third party clearing brokers maintain error accounts on behalf of Cboe Trading into which such positions settle, and we require the respective clearing broker to trade out of those positions as expeditiously as possible, which could result in our incurring trading losses. We may not effectively manage our growth, which could materially harm our business, financial condition and operating results. We expect that our business will continue to grow, which may place a significant strain on our management, personnel, systems and resources. We must continually improve our operational, financial and regulatory systems and managerial controls and procedures, and may need to continue to expand, train and manage our workforce. We must also maintain close coordination among our technology, legal, accounting, finance, marketing, sales, regulatory and compliance functions. If we fail to manage our growth effectively, our business, financial condition and operating results could be materially harmed. Furthermore, failure to successfully expand into new asset classes, such as the digital asset space or U.S. Treasuries, or new geographies may materially adversely affect our growth strategy and our future profitability. Our continued growth will require increased investment by us in technology, facilities, personnel, and financial and management systems and controls. It also will require expansion of our procedures for monitoring and assuring our compliance with applicable regulations, and we will need to integrate, train and manage a growing employee base. The expansion of our existing businesses, any expansion into new businesses and the resulting growth of our employee base will increase our need for internal audit and monitoring processes, which may be more extensive and broader in scope than those we have historically required. We may not be successful in identifying or implementing all of the processes that are necessary. Further, unless our growth results in an increase in our revenues that is proportionally greater than or equal to the increase in our costs associated with this growth, our business, financial condition and operating results may be materially adversely affected. We selectively explore acquisition opportunities and strategic alliances relating to other businesses, products or technologies. We may not be successful in integrating other businesses, products or technologies with our business. Any such transaction also may not produce the results we anticipate, which could materially adversely affect our business, financial condition and operating results. We selectively explore and pursue acquisition and other opportunities to strengthen our business and grow our Company. We may enter into business combination transactions, make acquisitions or enter into strategic partnerships, joint ventures or alliances, any of which may be material. The market for acquisition targets and strategic alliances is 41 Table of Contents highly competitive, which could make it more difficult to find appropriate merger or acquisition opportunities. If we are required to raise capital by incurring debt or issuing additional equity for any reason in connection with a strategic acquisition or investment, financing may not be available or the terms of such financing may not be favorable to us and our stockholders, whose interests may be diluted by the issuance of additional stock. For example, at the end of 2021, we announced the planned acquisitions of ErisX, an operator of a U.S. based digital asset spot market, a regulated futures exchange and a regulated clearinghouse, and NEO, a Canadian securities exchange with a diverse product and services set ranging from corporate listings to cash equity trading. These planned acquisitions are expected to close in the first half of 2022, subject to regulatory approvals and other customary closing conditions. Further, in 2021 we purchased Chi-X Asia Pacific, a holding company of alternative market operators in Australia and Japan, and in 2020, we purchased Hanweck and the assets of FT Options, which are providers of risk analytics market data, the assets of Trade Alert, a real-time alerts and order flow analysis service provider, EuroCCP, an operator of a European clearinghouse, and MATCHNow, an operator of an equities ATS in Canada. At the end of 2020, we also purchased BIDS Trading, a registered broker-dealer and operator of the BIDS ATS in the U.S., which is not a registered national securities exchange or a facility thereof. Cboe intends to maintain the BIDS ATS as an independently managed and operated trading venue, separate from and not integrated with the Exchanges. The process of integration, including in new geographies and asset classes with new regulatory regimes, may expose us to a number of unforeseen risks and operating difficulties, including risks relating to information technology integration and security, regulatory issues and employee issues, and may divert the attention of management from the ongoing operation of our business and harm our reputation. We may not successfully achieve the integration objectives, and we may not realize the anticipated cost savings, revenue growth and synergies in full or at all, or it may take longer to realize them than expected, any of which could negatively impact our business, financial condition and operating results. For additional risks related to our potential consummation of the ErisX acquisition, see the Risk Factors Section entitled “Risks Relating to Our Business Following Consummation of ErisX Acquisition” below. Risks Relating to Legal and Regulatory Matters We operate in a highly regulated industry and may be subject to censures, fines and other legal proceedings if we fail to comply with legal and regulatory obligations. Cboe Options, C2, BZX, BYX, EDGX, and EDGA are registered national securities exchanges and SROs, and, as such, are subject to comprehensive regulation by the SEC. CFE is a DCM and Cboe SEF is a SEF, each registered with the CFTC and subject to comprehensive regulation by the CFTC. In addition to its other SRO responsibilities, BZX, as a listing market, also is responsible for evaluating applications submitted by issuers interested in listing their securities on BZX and monitoring each issuer’s compliance with BZX’s continued listing standards. The Exchanges may be subject to additional responsibilities in other international jurisdictions where the Exchanges may be authorized to act as foreign exchanges. Failure to comply with these SRO and other responsibilities could result in potential sanctions or fines and a negative impact on Cboe’s reputation and/or branding. Our European businesses are subject to regulatory oversight in the UK by the FCA and in the Netherlands by the DNB and the AFM, which, through the “passporting” regime, provides authorization to carry on business in other Member States of the EU and the EEA in accordance with the applicable EU legislation and regulation to which our European business is subject. MATCHNow is subject to regulatory oversight in Canada by the IIROC and the OSC. Cboe Australia is subject to regulatory oversight in Australia by the ASIC. Cboe Japan is subject to regulatory oversight in Japan by the JFSA and the JSDA. BIDS Trading is a registered broker-dealer subject to regulatory oversight in the U.S. by the SEC and FINRA and is expected to be maintained as an independently managed and operated trading venue, separate from and not integrated with the SROs. The Chief Executive Officer of BIDS Trading is expected to lead BIDS Trading as an independent business within Cboe, reporting into an independent committee of the Board of Directors of Cboe Global Markets. If a regulatory authority makes a finding of non-compliance, conditional fines could be imposed, and our licenses could be revoked. Any such fine or revocation of a license could have a material adverse effect on our business, financial condition and operating results. In addition to the requirements related to operating our U.S. markets imposed by the SEC and the CFTC, we also have certain responsibilities for regulating the TPHs and members that trade on our Exchanges. While we have entered into agreements under which FINRA, with respect to our options and equities exchanges provides certain regulatory services, we retain ultimate responsibility for the regulation of our TPHs and members. We have begun to perform 42 Table of Contents internally more of the regulatory services that FINRA used to handle and now perform internally the regulatory functions that NFA previously handled on behalf of CFE. Our ability to comply with applicable laws and rules is largely dependent on the establishment and maintenance of appropriate systems and procedures, our ability to attract and retain qualified personnel, the ability of FINRA and OCC to perform under their respective RSAs, the ability of FINRA and OCC to transition to us any other potential responsibilities under their respective RSAs, our ability to complete the new additional responsibilities for regulating our TPHs and members and our oversight of the work done by FINRA and OCC. The SEC and CFTC have broad powers to audit, investigate and enforce compliance and to punish noncompliance by, as applicable, SROs, DCMs and SEFs pursuant to applicable laws, rules and regulations. If a regulatory authority were to find one of our programs of enforcement or compliance to be deficient, our SROs, DCM, or SEF could be the subject of investigations and enforcement proceedings that may result in substantial sanctions, including revocation of registration as a national securities exchange, DCM, or SEF. Any such investigations or proceedings, whether successful or unsuccessful, could result in substantial costs, the diversion of resources, including management time, and potential harm to our reputation, which could have a material adverse effect on our business, financial condition and operating results. In addition, our SROs, DCM, or SEF may be required to modify or restructure their regulatory functions in response to any changes in the regulatory environment, or they may be required to rely on third parties to perform regulatory and oversight functions, each of which may require us to incur substantial expenses and may harm our reputation if our regulatory services are deemed inadequate. In addition, SROs are required by federal law to perform a variety of regulatory functions. In light of these responsibilities, some courts have held that SROs are immune to certain private causes of action relating to the performance of these regulatory functions. There is a risk that some courts may not apply this immunity doctrine to all claims. There is also a risk that legislative or regulatory developments may change the application of this immunity doctrine. Limitations on the application of the immunity doctrine could result in an increased exposure to litigation, and increase liability and/or other legal expenses. Further under the Commodity Exchange Act, CFE and Cboe SEF may be subject to litigation alleging that they have acted in bad faith. We also could be exposed to liability to regulators or other governmental authorities even in situations where immunity would bar a civil claim. Legislative or regulatory changes affecting our markets could have a material adverse effect on our business, financial condition and operating results. Changes in regulation by the SEC, CFTC, FCA, Central Bank of the Netherlands (“DNB”), AFM, IIROC, OSC, ASIC, JFSA, JSDA, other foreign regulators or other government action, including SEC approval of rule filings by other SROs or entities, including OCC, could materially affect our markets, products and clearinghouse. In recent years, the securities and derivatives industries have been subject to regulatory changes as a result of increasing government and public scrutiny of the securities and derivatives industries. We have also experienced, and we may also experience due to changes in administrations in the U.S. and expansion into other asset classes, such as the digital asset space or U.S. Treasuries and geographies, an increase in rulemaking and legislation that could affect our business. Further, Congress, regulators and some media have been increasingly scrutinizing electronic trading, payment for order flow and other forms of remuneration, and the structure of equity markets in recent years. The SEC continues to consider various potential market structure changes, which could result in reduced trading volumes, or which could negatively affect our business. To the extent the SEC adopts regulatory changes, our business, financial condition and operating results could be negatively impacted. In addition, high frequency trading has been the subject of private litigation and we are party to one such matter. See Note 23 (“Commitments, Contingencies, and Guarantees—Legal Proceedings”) for more information. To the extent the SEC adopts additional regulatory changes related to market data and access and capacity, our business, financial condition and operating results could be negatively impacted. Under EU and UK regulations, European and UK banks and other European and UK financial institutions become subject to punitive capital charges if they transact options or futures through a third country central counterparty (“CCP”) that is not recognized in the applicable jurisdiction. OCC, our clearinghouse for U.S. options and futures, is not currently recognized as a third country CCP by the EU or the UK. However, the European Commission has issued equivalency determinations for CCPs regulated by the CFTC and SEC, which includes OCC, and OCC’s application for recognition as a third country CCP in the EU is pending. The UK has not issued any equivalency determination with respect to U.S. CCPs, and accordingly OCC has not yet submitted its application for recognition in the UK but is instead operating under the UK’s temporary recognition regime. As a prerequisite to ultimately achieving recognition in the EU or UK, it is possible that OCC could be required by the EU or UK to contribute capital to its default waterfall applicable in the event of clearing 43 Table of Contents member default. This capital could be required to be drawn before the default fund contributions of non-defaulting clearing members in the event that a defaulting clearing member’s margin and other contributions were to be exhausted. OCC’s stockholders, including Cboe Options, could effectively be required to fund this capital. If the EU or UK do not recognize OCC as a third country CCP, then European or UK market participants that clear through OCC would become subject to punitive capital charges. As a result, we could experience the loss of a significant number of European or UK market participants and a significant reduction in trading activity on our options and futures markets, which could have a material adverse effect on our business, financial condition and operating results. The implementation of MiFID II and MiFIR in Europe at the beginning of 2018 has encouraged competition among market centers in Europe. MiFID II and MiFIR have introduced a number of new rules, including enhanced internal organizational and compliance monitoring requirements, which apply directly to European trading venues such as our MTF and RM. The impact of MiFID II and MiFIR is significant, and the increased competition among market centers could reduce trading volumes and trading fees, while increasing our costs of operating in Europe. Additionally, European authorities are planning to continue to review MiFID in the second half of 2021 as a result of which new rules may come into effect that could have a material impact on our business. As discussed above, in 2021 the E.C. and ESMA published proposals for the review of EU market structure, including provisions for a consolidated tape for the EU, changes to the transparency regime for equities, increased pre-trade transparency for periodic auctions, and post-trade flagging. These proposals are expected to be implemented from the middle of 2022 to late 2023 or early 2024. As proposed, these new rules may have a material adverse effect on our business, financial condition and operating results. The legislative and regulatory environment in which the spot FX market operates is evolving and has undergone significant changes in the recent past, and there may be future regulatory changes in the spot FX industry. The FX Global Code was published in 2017 and sets forth standards of conduct agreed by market participants and central banks on a global basis to apply to the wholesale FX market, and the effect of its publication on conduct and future regulation continues to evolve. Cboe FX issued a Statement of Commitment declaring its commitment to conduct its FX market activities in a manner consistent with the principles of the FX Global Code. Amendments to the FX Global Code, changes in the interpretation or enforcement of existing laws and regulations by applicable governmental bodies and regulatory organizations, or the adoption of new legal or regulatory requirements, may also adversely affect our spot FX business. Further, our FX NDF business may also be adversely affected by proposed regulatory changes to the rules governing swap execution facilities.   It is also possible that there will be additional legislative and regulatory changes or efforts in the environment in which we operate, or plan to operate, our businesses. Actions on any of the specific regulatory issues currently under review in the U.S. or internationally and other proposals could have a material impact on our business. In addition, U.S. and foreign legislatures and regulators could impose legislative or regulatory changes that could materially adversely impact the ability of our market participants to use our markets or participate in the securities industry at all. Any such changes could result in the loss of a significant number of market participants or a reduction in trading activity on our markets, either of which could have a material adverse effect on our business, financial condition and operating results. Changes or proposed changes in regulation may also result in additional costs of compliance and modification of market participants’ trading activity on our Exchanges and markets. Any infringement by us on intellectual property rights of others could result in litigation and could have a material adverse effect on our operations. Our competitors, as well as others, have obtained, or may obtain, patents or may otherwise hold intellectual property rights that are related to our technology or the types of products and services we offer or plan to offer. We may not be aware of all intellectual property that may pose a risk of infringement by our products, services or technologies. In addition, some potential patent applications in the U.S. are confidential until a patent is issued, and therefore we cannot evaluate the extent to which our products, services or technologies may be covered or asserted to be covered in pending patent applications. Thus, we cannot be sure that our products, services or technologies do not infringe on the rights of others or that others will not make claims of infringement against us. Claims of infringement are not uncommon in our industry, and even if we believe that such claims are without merit, they can be time-consuming and costly to defend and divert management resources and attention. If one or more of our products, services or technologies were determined to infringe a patent or other intellectual property right held by another party, we may be required to pay damages, stop using, developing or marketing those products, services or technologies, obtain a license from the intellectual property rights holders, or redesign those products, services or technologies to avoid infringement. If we were required to stop using, 44 Table of Contents developing or marketing certain products, services or technologies, our business, financial condition and operating results could be materially harmed. Moreover, if we were unable to obtain required licenses, we may not be able to redesign our products, services or technologies to avoid infringement, which could materially adversely affect our business, financial condition and operating results. Misconduct by our TPHs, members, participants or others could harm us. We run the risk that our TPHs, members, participants, other persons who use our markets or our products, other persons for whom we clear transactions, our employees or those with which we have business relationships may engage in fraud, market or product manipulation, or other misconduct, which could result in regulatory and legal sanctions and penalties and serious harm to our reputation, especially because we are the parent company of SROs. It is not always possible to deter misconduct, or market or product manipulation, and the precautions we take to prevent and detect this activity may not be effective in all cases. In addition, misconduct, or market or product manipulation by, or failures of, participants on our or other exchanges may discourage trading on our Exchanges or of our products, which could reduce revenues. Potential conflicts of interest between our for-profit status and our regulatory responsibilities may adversely affect our business. As a for-profit business with regulatory responsibilities, we are responsible for disciplining TPHs and members for violating our rules, including by imposing fines and sanctions. This may create a conflict of interest between our business interests and our regulatory responsibilities. Any failure by us to fulfill our regulatory obligations could significantly harm our reputation, increase regulatory scrutiny or cause the SEC or CFTC to take action against us, all of which could materially adversely affect our business, results of operations or financial condition. BIDS Trading’s ability to operate under its current regulatory framework is dependent upon the sufficiency of a novel operational and governance framework we have developed to govern our relationship with BIDS Trading and our ability to comply with such framework and if we fail to adhere to such framework or the BIDS Trading ATS is otherwise deemed a “facility” of our registered national securities exchanges, our business, financial condition and operating results may be adversely affected. ​ The U.S. equities ATS operated by BIDS Trading is regulated as a broker-dealer sponsored alternative trading system and not a registered national securities exchange. Because we acquired BIDS Trading, it is now under common ownership with our registered national securities exchanges that, in some cases, offer trading in the same securities as those traded on the BIDS Trading ATS. Absent sufficient separation, this common ownership of an ATS and registered national securities exchanges offering trading in the same securities presents the potential for the BIDS Trading ATS to be deemed a “facility” of our registered national securities exchanges. If the BIDS Trading ATS were to be deemed to be a “facility” of our registered national securities exchanges, certain exchange regulations could be extended to the BIDS Trading ATS, which could have a material adverse impact on BIDS Trading’s business model. This could reduce the BIDS Trading ATS’ competitiveness and volumes and could result in a reduction of the value of the BIDS Trading ATS to us. This could also potentially result in fines or other penalties being assessed against us for our failure to operate the BIDS Trading ATS as a “facility,” which could have a material adverse effect on our business, financial condition and operating results. ​ To mitigate the risk that the BIDS Trading ATS is deemed a “facility” of our registered national securities exchanges, we have developed and implemented an operational and governance framework for our ownership of BIDS Trading that is intended to preserve the strategic, technological, business, and operational independence of the BIDS Trading ATS from our registered national securities exchange businesses, such that the BIDS Trading ATS and our registered national securities exchanges would not be deemed to be integrated or otherwise linked for “facility” purposes. This framework is supported by highly detailed policies, procedures and controls. However, because of the lack of precedent for common ownership of an ATS and registered national security exchanges offering trading in the same securities, there is risk that our framework and supporting policies, procedures and controls could be deemed to be insufficient to prevent the BIDS Trading ATS from being deemed to be a “facility” of our registered national securities exchanges. In addition, because of the comprehensive and highly detailed nature of our framework and supporting policies, procedures and controls, there is risk that we could inadvertently fail to fully adhere to our operational and governance framework and related policies, procedures and controls. There is also risk that new legislation or regulation, or changes in existing regulation or other government action, relating to “facilities” of registered national securities exchanges and/or the common ownership of an ATS and registered national securities exchanges offering trading in the same securities could materially affect our ability to own and operate the BIDS Trading ATS under the current operational and governance framework, including without the BIDS Trading ATS being deemed a “facility” of our registered national securities exchanges. Occurrence of any of the 45 Table of Contents risks described in this paragraph could result in the BIDS Trading ATS being deemed to be a “facility” of our registered national securities exchanges, which could reduce the BIDS Trading ATS’ competitiveness and volumes and could result in a reduction of the value of the BIDS Trading ATS to us, and could also potentially result in fines or other penalties being assessed against us for our failure to operate the BIDS Trading ATS as a “facility,” which could have a material adverse effect on our business, financial condition and operating results. If our risk management and compliance methods are not effective, our business, financial condition and operating results may be adversely affected. Our ability to comply with applicable laws and rules is largely dependent on our establishment and maintenance of compliance, risk, audit, and reporting systems and procedures, as well as our ability to attract and retain qualified compliance, risk and audit management personnel. These systems and procedures may not be fully effective. We face the risk of intervention by regulatory authorities, including extensive examination and surveillance activity. In the case of actual or alleged non-compliance with applicable laws or regulations, we could be subject to investigations and judicial or administrative proceedings that may result in penalties, settlements or civil lawsuits, including by customers, or third parties, for damages, which may be substantial. For example, the SEC has previously brought actions against exchange operators, including us, for failing to fulfill their obligations to have an effective regulatory system. Any failure to comply with applicable laws and rules could materially adversely affect our business, reputation, financial condition and operating results and, in extreme cases, our ability to conduct our business or portions thereof. As the parent company for SROs, other markets, and a clearinghouse, we are responsible for maintaining markets that comply with securities and futures laws, SEC, FCA, AFM, DNB, IIROC, OSC, ASIC, JFSA, JSDA, ESMA, and CFTC regulations and the rules of the respective exchanges, markets and clearinghouse. We have methods to identify, monitor and manage our risks. Management of legal, compliance, and regulatory risk, among other risks, requires policies and procedures to properly monitor and manage risk. If our policies, procedures, and compliance systems are not effective or we are not successful in monitoring or evaluating the risks to which we are or may be exposed, our business, reputation, financial condition and operating results could be materially adversely affected. We cannot provide assurance that our policies and procedures will always be effective, or that our management, compliance department, risk department and related enterprise risk management program and internal audit department would be able to identify any such ineffectiveness. If these departments or the enterprise risk program, and related policies and procedures are not effective, we may be subject to monetary or other penalties by our regulators, and our insurance policies may not provide adequate coverage. Our ability to implement or amend rules could be limited or delayed because of regulation, which could negatively affect our ability to implement needed changes. Our Exchanges registered with the SEC must submit proposed rule changes to the SEC for its review and, in many cases, its approval. Even where a proposed rule change may be effective upon filing with the SEC, the SEC retains the right to suspend and disapprove such a rule change. Also, the CFTC may stay or disapprove rules that we file with it for CFE or Cboe SEF. The rule review process can be lengthy and can significantly delay the implementation of proposed rule changes that we believe are necessary to the operation of our markets. If the SEC or CFTC delays, including because of a government shutdown, or does not allow one of our Exchanges to implement a rule change, this could negatively affect our ability to make needed changes or implement business activities. Similarly, the SEC must approve amendments to our exchange subsidiaries’ certificates of incorporation and bylaws as well as certain amendments to the certificate of incorporation and bylaws of Cboe Global Markets. The SEC may decide not to approve a proposed amendment or may delay such approval in a manner that could negatively affect our ability to make a desired change, which could prevent or delay us from improving the operations of our markets or recognize income from new products. Changes in the tax laws and regulations affecting us, our products and our market participants could have a material adverse effect on our business. Legislation may be proposed, both domestically and internationally, that could add a transaction tax on our products or change the way that our market participants are taxed on the products they trade on our markets. More recently, a number of federal, state and local jurisdictions in the U.S. and EU Member States have considered a financial transaction tax, but many details remain to be discussed and agreed, including how to assess the tax. Additionally, the proposed Modernization of Derivatives Tax Act of 2021 would introduce in the U.S. mark-to-market tax treatment for all derivatives contracts and require gains and losses be taxed at ordinary income tax rates. If such proposals were to become law, they 46 Table of Contents could have a negative impact on the securities industry and on us by making transactions more costly to market participants, which may impact derivatives trading behavior, reduce trading or clearing and could make our markets less competitive, and they could result in a reduction in volumes and liquidity, which would have a negative impact on our operations. In addition to proposed tax changes that could affect our market participants, like other corporations, we are subject to taxes at federal, state and local levels, as well as in non-U.S. jurisdictions. Changes in tax laws, regulations or policies or successful claims by tax authorities could result in our having to pay higher taxes, which would in turn reduce our net income. If this occurs, we may experience a higher effective tax rate. We are subject to litigation risks and other liabilities. Many aspects of our business involve substantial risks of litigation and other liabilities. Although under current law we expect to be immune from private suits arising from conduct within our regulatory authority and from acts and forbearances incident to the exercise of our regulatory authority, we expect this immunity will only cover certain of our activities in the U.S., and we could be exposed to liability under foreign, national and local laws, court decisions and rules and regulations promulgated by regulatory agencies. Some of our other liability risks arise under the laws and regulations relating to the tax, employment, intellectual property, anti-money laundering, technology export, cybersecurity, foreign asset controls, foreign corrupt practices, employee labor and employment areas, including anti-discrimination and fair-pay laws and regulations. Liability could also result from disputes over the terms of a trade executed on one of our markets, claims that a system failure or delay cost a customer money, claims we entered into an unauthorized transaction or claims that we provided materially false or misleading statements in connection with a transaction. For example, we are subject to on-going legal disputes that could result in the payment of fines, penalties or damages and could expose us to additional liability in the future. See Item 3 “Legal Proceedings” in this Annual Report for a general description of our legal proceedings and claims and Note 23 (“Commitments, Contingencies, and Guarantees – Legal Proceedings”) to the consolidated financial statements and related notes, which are included elsewhere in this Annual Report, for a summary of specific legal proceedings. Further, we could incur significant expenses vigorously defending the claims mentioned above (including those found to be barred due to immunity) and any future claims, even those without merit, which could adversely affect our business, financial condition and operating results. The outcomes of existing claims and any future claims cannot be determined and an adverse resolution of any lawsuit or claim against us may require us to pay substantial damages or impose restrictions on how we conduct business, either of which could adversely affect our business, financial condition and operating results. In addition, we may have to establish accruals for those matters in circumstances when a loss contingency is considered probable and the related amount is reasonably estimable. Any such accruals may be adjusted as circumstances change. Risks Related to Our Common Stock and Indebtedness We have outstanding indebtedness, which may decrease our business flexibility and adversely affect our business, financial condition and operating results. As of December 31, 2021, we had $159.5 million outstanding under our term loan facility, $646.5 million of senior unsecured notes due 2027, $493.3 million of senior unsecured notes due 2030, no funds outstanding under our revolving credit facility and no funds outstanding under the EuroCCP credit facility. The financial and other covenants to which we have agreed and our indebtedness may have the effect of reducing our flexibility to respond to changing business and economic conditions, thereby placing us at a competitive disadvantage compared to competitors that have less indebtedness and making us more vulnerable to general adverse economic and industry conditions. Further, we may default on our obligations or violate the covenants, in which case, we may be required to seek a waiver of such default or the debt obligations may be accelerated. A default under any of our indebtedness with cross default provisions could result in a default on our other indebtedness. Our indebtedness may also increase future borrowing costs, and the covenants pertaining thereto may also limit our ability to repurchase shares of our common stock, increase dividends or obtain additional financing to fund working capital, capital expenditures, acquisitions or general corporate requirements. We are also required to dedicate a larger portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow for other purposes, including working capital, capital expenditures and 47 Table of Contents general corporate purposes. Further, a portion of our borrowings are at variable rates of interest, which exposes us to the risk of increased interest rates unless we enter into offsetting hedging transactions. Our ability to make payments on and to refinance our debt obligations and to fund planned capital expenditures depend on our ability to generate cash from our operations. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. We may not be able to refinance any of our indebtedness on commercially reasonable terms, or at all. If we cannot service our indebtedness, we may have to take actions such as selling assets, seeking additional equity or reducing or delaying capital expenditures, strategic acquisitions, investments and alliances, any of which could impede the implementation of our business strategy or prevent us from entering into transactions that would otherwise benefit our business. Additionally, we may not be able to affect such actions, if necessary, on commercially reasonable terms, or at all. Any of the foregoing consequences could materially adversely affect our business, financial condition and operating results. Deterioration in our credit profile may increase our costs of borrowing money. As of December 31, 2021, we have investment grade credit ratings from S&P Global Ratings (A-) and Moody’s Investor Service (A3). Ratings from credit agencies are not recommendations to buy, sell or hold our securities, and each rating should be evaluated independently of any other rating. There is no assurance that we will maintain such credit ratings, since credit ratings may be lowered or withdrawn entirely by a rating agency if, in its judgment, the circumstances warrant. If a rating agency were to downgrade our rating below investment grade, our borrowing costs could increase. If our goodwill, long-lived assets, investments in non-consolidated subsidiaries and intangible assets become impaired, the resulting charge to earnings may be significant. We are required to assess investments in non-consolidated subsidiaries and intangible assets for impairment at least annually. Goodwill impairment testing is performed annually in the fiscal fourth quarter or more frequently if conditions exist that indicate that the asset may be impaired. In the future, we may take charges against earnings resulting from impairment. Any determination requiring the write-off of a significant portion of our goodwill, long-lived assets, intangible assets or investments in non-consolidated subsidiaries could materially adversely affect our results of operations and financial condition. Any decision to pay dividends on our common stock is at the discretion of our Board of Directors and depends upon the earnings and cash flow of our operating subsidiaries. Accordingly, there can be no guarantee that we will pay dividends to our stockholders. Any decision to pay dividends on our common stock in the future will be at the discretion of our Board of Directors, which may determine not to declare dividends at all or at a reduced amount. The board’s determination to declare dividends will depend upon our profitability and financial condition, contractual restrictions, restrictions imposed by applicable law and the SEC and other factors that the board deems relevant. As a holding company with no significant business operations of its own, Cboe Global Markets depends entirely on distributions, if any, it may receive from its subsidiaries to meet its obligations and pay dividends to its stockholders. If these subsidiaries are not profitable, or even if they are and they determine to retain their profits for use in their businesses, we will be unable to pay dividends to our stockholders. Certain provisions in our organizational documents and governing law could prevent or delay a change of control. Our organizational documents contain provisions that could block actions that stockholders might find favorable, including discouraging, delaying or preventing a change of control or any unsolicited acquisition proposals for us. These include provisions: ● prohibiting stockholders from acting by written consent; ● requiring advance notice of director nominations and of business to be brought before a meeting of stockholders; and ● limiting the persons who may call special stockholders’ meetings. ​ ​ 48 Table of Contents In addition, our organizational documents include provisions that: ​ ● restrict any person from voting or causing the voting of shares of stock representing more than 20% of our outstanding voting capital stock; and ● restrict any person from beneficially owning shares of stock representing more than 20% of the outstanding shares of our capital stock. Furthermore, our Board of Directors has the authority to issue shares of preferred stock in one or more series and to fix the rights and preferences of these shares without stockholder approval. Any series of our preferred stock is likely to be senior to our common stock with respect to dividends, liquidation rights and, possibly, voting rights. The ability of the Board of Directors to issue preferred stock also could have the effect of discouraging unsolicited acquisition proposals, thus materially adversely affecting the market price of our common stock. Delaware law makes it difficult for stockholders that have recently acquired a large interest in a corporation to cause the merger or acquisition of the corporation against the board’s wishes. Under Section 203 of the Delaware General Corporation Law, a Delaware corporation may not engage in any merger or other business combination with an interested stockholder for a period of three years following the date that the stockholder became an interested stockholder except in limited circumstances, including by approval of the corporation’s Board of Directors. Furthermore, the European countries where we operate regulated entities, such as the UK and Netherlands, may require prior governmental approval before an investor acquires 10% or more of the outstanding shares of our common stock. Risks Relating to Our Business Following Consummation of Pending ErisX Acquisition We may not realize the expected benefits of our pending acquisition of ErisX and the acquisition introduces additional risks to our business due to its evolving business model. We expect to acquire ErisX, a U.S.-based digital asset spot market, a regulated futures exchange and a regulated clearinghouse, which we plan to rebrand as Cboe Digital following close. This planned acquisition is expected to close in the first half of 2022, subject to regulatory approvals and other customary closing conditions. Leveraging digital asset data from ErisX’s and our existing index calculation capabilities, we intend to develop and distribute digital asset indices for potential use in exchange traded products and other derivative product opportunities. We also plan to develop a robust market data offering based on actionable bid and offer prices from the ErisX spot crypto market, and ultimately intend to develop a benchmark to help ErisX’s industry partners and other market participants evaluate the appropriateness of crypto execution prices and offer digital asset trading to their clients. We expect to have increased financial and reputational risks if there is a failure to develop and launch one or more of anticipated products resulting from this potential acquisition, or if the development or launch of a new product is unsuccessful. Also, there can be no assurance that we will be able to maintain the necessary regulatory approvals or receive support from market participants, industry partners and users to develop and launch products as planned, that ErisX will continue to operate as anticipated, or that we will realize the expected return on our investment. Furthermore, our potential investment in ErisX entails numerous risks, including risks relating to our ability to: ● manage the complexity of its business model to stay current with the industry; ● successfully enter categories and markets in which it may have limited or no prior experience; ● successfully develop and integrate products, systems or personnel into its business operations; and ● maintain required licenses and regulatory approvals for its business. In addition, we expect that certain market participants intend to acquire minority ownership interests in Cboe Digital and to serve as partners in the growth of the business. If these market participants do not acquire minority ownership interests or serve as partners in the growth of the business, then we may not be able to realize the expected return on our investment. Insufficient participation from market participants in ownership and partnership may adversely affect the ability of ErisX to operate as anticipated or grow, which may have a material adverse effect on our business following the acquisition. As digital assets technologies evolve, once under our management, ErisX may add, modify or discontinue certain aspects of its business model relating to the product mix and service offerings. Future additions and modifications to ErisX’s business will increase the complexity of its business and may place significant strain on ErisX’s management, personnel, operations, systems, technical performance, financial resources and internal financial control and reporting 49 Table of Contents functions. We cannot offer any assurance that these or any other additions or modifications will be successful or will not result in harm to our business following the acquisition. Additionally, sources of ErisX revenue are dependent on digital assets and the broader blockchain ecosystem. Due to the highly volatile nature of the blockchain ecosystem and the prices of digital assets, ErisX’s operating results have fluctuated, and may continue to fluctuate, significantly from period to period in accordance with market sentiments and movements in the broader blockchain ecosystem. Additionally, the blockchain ecosystem is highly innovative, rapidly evolving and characterized by intense competition, experimentation and frequent introductions of new products and services, and is subject to uncertain and evolving industry and regulatory requirements. We expect competition to increase in the future as existing and new competitors introduce new products or enhance existing products that may compete with ErisX. We have limited experience in the digital assets space, and ErisX has limited experience applying its digital platform to a global exchange and clearing infrastructure for digital assets. The creation and operation of a global cryptocurrency spot and derivatives trading market is subject to potential technical, legal and regulatory constraints. Any problems that we encounter with the operation of the ErisX systems, including technical, legal and regulatory problems, could negatively impact our business and plan of operations following the acquisition. ErisX may be unsuccessful in retaining its key personnel. The success of ErisX will depend in part on the ability to retain its key employees, while the acquisition is pending and following our acquisition of ErisX. If ErisX is unable to retain key employees, including management, who are critical to the successful integration and future operations, we and ErisX could face disruptions in our respective operations, loss of customers, loss of key information, expertise or know-how and unanticipated additional recruitment costs. In addition, if key employees terminate their employment, ErisX’s business activities may be adversely affected and management’s attention may be diverted from successfully integrating ErisX to hiring suitable replacements, all of which may cause ErisX’s business to suffer. In addition, hiring qualified and experienced personnel in this specialized technology space is difficult due to the high level of competition and scarcity of experience. We and ErisX may have difficulty finding, hiring and integrating qualified employees to fill positions following the acquisition. The characteristics of digital assets and digital asset platforms have been, and may in the future continue to be, exploited to facilitate illegal activity such as fraud, money laundering, tax evasion, ransomware scams and other types of cybercrime, as well as other technical issues, which could adversely affect ErisX. Digital assets and the digital asset industry are relatively new and, in many cases, lightly regulated or largely unregulated. Digital asset platforms on which digital assets trade pose special risks, as these platforms are generally new and the rules governing their activities are unsettled and their activities may be largely unregulated, and may therefore be more exposed to theft, fraud, and failure than established, regulated exchanges for other products. Some types of digital assets, particularly cryptocurrencies, have characteristics, such as the speed with which transactions can be conducted, the ability to conduct transactions without the involvement of regulated intermediaries, the ability to engage in transactions across multiple jurisdictions, the irreversible nature of certain transactions and encryption technology that anonymizes these transactions, that make those assets potentially susceptible to use in illegal activity such as fraud, money laundering, tax evasion, ransomware scams and other types of cybercrime. Digital asset platforms have been shut down or experienced losses of assets placed on the platform as a result of cybercrime, and any such event is likely to result in the complete loss of assets placed on such a platform. Any governmental or regulatory action against such a digital asset trading platform may cause assets on such platform to become frozen for a substantial period of time or forfeited, and could result in material opportunity costs or even in the total loss of such assets. In addition, banks may refuse to process or support wire transfers to or from digital asset trading platforms. While we believe that ErisX’s risk management and compliance framework is reasonably designed to detect any such illicit activities, we cannot ensure that we and ErisX will be able to detect such illegal activity in all instances. Because the speed, irreversibility and anonymity of certain digital asset transactions potentially makes them difficult to track, fraudulent transactions may be more likely to occur. ErisX may be specifically targeted by individuals seeking to conduct transfers for fraudulent purposes, and it may be difficult or impossible for us and ErisX to detect and avoid such transactions in certain circumstances. Various other technical issues with blockchain networks have also been uncovered from time to time that resulted in disabled functionality, exposure of certain users’ personal data, theft of users’ assets, and other negative consequences, and which required resolution with the attention and efforts of their global miner, user and development communities. If any 50 Table of Contents such risks or other risks materialize, the development and growth of digital assets may be significantly affected and, as a result, ErisX’s business, operating results and financial condition could be adversely affected. The acquisition of ErisX may increase regulatory costs and risks, and there can be no assurance that our or ErisX’s employees or agents will not violate applicable laws and regulations. Various aspects of the business that ErisX is engaging in, or planning to engage in, are heavily regulated. ErisX's futures exchange and clearinghouse are regulated by the CFTC, and ErisX's clearinghouse is registered with the Financial Crimes Enforcement Network and is licensed as a money transmitter in many U.S. states and territories. The trading, clearance, and settlement of digital asset transactions may be subject to the federal securities laws and regulated by the SEC if the asset is considered a security. We and ErisX are also subject to federal and state anti-money laundering and counter-terrorism financing laws and regulations. We and ErisX currently maintain policies and procedures designed to reasonably help ensure compliance with applicable laws and regulations, but there can be no assurance that our or ErisX’s employees or agents will not violate such laws and regulations. A failure by us or ErisX, including the respective employees or agents, to comply with such laws and regulations and subsequent judgment or settlement against us or ErisX under these laws could subject us or ErisX to monetary penalties, damages, and/or have a significant reputational impact. Regulatory or other legislative changes or actions may restrict the use of digital assets in a manner that adversely affects ErisX’s business, prospects or operations and, consequently, our potential investment in ErisX. Regulatory or other legislative changes or actions may impact the ability of ErisX to continue to operate, and such actions could affect the ability of ErisX to continue as a going concern. The regulatory and legislative framework is unsettled with respect to many forms of digital assets, which means that federal or state regulators or legislators may in the future curtail or prohibit the acquisition, use or redemption of certain digital assets. Ownership of, holding or trading in certain digital assets may become subject to sanction. Federal or state regulators or legislators may also take regulatory or legislative action that may increase the cost and/or subject companies to additional regulations and laws regarding custody or facilitating the trading of digital assets. In addition, as ErisX expands its business to new products and services, it will come under the jurisdiction of additional regulators - both with respect to jurisdiction and subject matter. Any failure or perceived failure to comply with existing or new laws, regulations, or orders of any governmental authority (including changes to or expansion of the interpretation of those laws, regulations, or orders), including those discussed in this risk factor, may subject us and ErisX to significant fines, penalties, criminal and civil lawsuits, forfeiture of significant assets, and enforcement, result in additional compliance and licensure requirements, increase regulatory scrutiny of its business, restrict ErisX’s operations, and force ErisX to change its business practices, make product or operational changes, or delay planned product launches or improvements. We and ErisX currently maintain policies and procedures designed to reasonably help ensure compliance with applicable laws and regulations, but there can be no assurance that our or ErisX’s employees, contractors, or agents will not violate such laws and regulations. Digital asset custodial solutions and related technology, including ErisX’s systems and custodial arrangements, are subject to risks related to a loss of funds due to theft of digital assets, employee or vendor sabotage, security and cybersecurity risks, system failures and other operational issues which could cause damage to our and ErisX’s reputation and brand.   The secure storage and transmission of digital assets and data over networks is a critical element of ErisX’s operations. Threats to ErisX’s storage and transmission of digital assets and data may come from external factors such as governments, organized crime, hackers and other third parties such as outsourced or infrastructure-support providers and application developers, or may originate internally from an employee or service provider to whom ErisX has granted access to its systems. Digital asset transactions may be irrevocable, and stolen or incorrectly transferred digital assets may be irretrievable. Once a transaction has been verified and recorded in a block that is added to the blockchain, an incorrect transfer of a digital asset generally will not be reversible, and ErisX may not be capable of seeking compensation for any such transfer or theft. It is possible that, through computer or human error, or through theft or criminal action, the digital asset could be transferred in incorrect amounts or to unauthorized third parties, or to uncontrolled accounts. Such events would have a material adverse effect on the ability of ErisX to continue as a going concern, which may have an adverse effect on our business following the acquisition. 51 Table of Contents While we and ErisX maintain cybersecurity procedures and policies, those procedures and policies may not be adequate to avoid the potential losses caused by security breaches, and ErisX may lose digital assets without any recourse. Unlike bank accounts or accounts at some other financial institutions, in the event of loss or loss of utility value, there is no public insurer, such as the Securities Investor Protection Corporation or the FDIC, to offer recourse to us, ErisX, or to any investor and the misappropriated digital assets may not easily be traced to the bad actor. Further, when cryptocurrency custodial solutions (whether involving ErisX systems or others) experience system failures or other operational issues, such events could result in a reduction in cryptocurrency prices or confidence and impact the success of ErisX and have a material adverse effect on the ability of ErisX to continue as a going concern, which may have an adverse effect on our business following the acquisition. ErisX’s clearinghouse operations are exposed to risks, including credit, liquidity, market and other risks related to the potential defaults of clearing members and other counterparties. ErisX is subject to risks related to operating its clearinghouse, Eris Clearing, which is a derivatives clearing organization (“DCO”), registered with the CFTC. Risks associated with the operation of Eris Clearing include failing to meet strict business continuity requirements and regulatory oversight, risks of default by clearing members and counterparties due to bankruptcy, lack of liquidity, operational failure or other reasons, and the risks associated with the adequacy of participants’ margin and guaranty funds. There is no guarantee the collateral deposited will continue to maintain its value, and the use of digital assets as collateral may introduce additional volatility in value. Please also refer to the risk factors above for a discussion of other risks associated with the use of digital assets. These risks could subject ErisX to substantial losses, reputational harm, regulatory consequences, including litigation, fines and enforcement actions, and the inability to operate its business.

See Note 7 (“Property and Equipment, Net”) and Note 24 (“Leases”) to the consolidated financial statements included herein for further information. ​ ​ 53 Table of Contents Item 3.Legal Proceedings Cboe incorporates herein by reference the discussion set forth in Note 21 (“Income Taxes”) and Note 23 (“Commitments, Contingencies, and Guarantees”) of the consolidated financial statements included herein. CT Plan Order (Continuation of Consolidated Data Plans Proceeding) ​ On May 6, 2020, the SEC issued an order (the “Consolidated Data Plan Order”) that directed the U.S. equities exchanges and FINRA to submit a new National Market System (“NMS”) Plan regarding Consolidated Equity Market Data. The contemplated new NMS Plan is referred to as the “CT Plan” and it will replace three Equity Data Plans that govern the dissemination of real-time, consolidated market data for NMS stocks. The Consolidated Data Plan Order set forth certain changes to be included in the proposed CT Plan, including governance structure changes related to voting rights and a deadline of August 11, 2020 by which the proposed CT Plan had to be filed. ​ On June 29, 2020, the Company filed a Petition for Review (“PFR”) with the Court of Appeals for the D.C. Circuit Court (“D.C. Circuit) challenging the Consolidated Data Plan Order. Briefing concluded on March 12, 2021 and oral argument was held on April 26, 2021. On June 15, 2021, the D.C. Circuit issued an order dismissing the PFR for lack of jurisdiction, holding that the Consolidated Data Plan Order was not a “final order” because the SEC had not determined whether the challenged features would make it into the new CT Plan. ​ On August 6, 2021, the SEC issued an order approving the CT Plan that was previously filed on August 11, 2020 (as mandated by the Consolidated Data Plan Order) and subject to public comment (“CT Plan Order”). On August 9, 2021, the Company filed another PFR with the D.C. Circuit challenging the CT Plan Order and the prior Consolidated Data Plan Order. On September 13, 2021, the Company filed a motion requesting that the D.C. Circuit stay the CT Plan Order pending resolution of the appeal and also requesting that the D.C. Circuit expedite the appeal. On October 13, 2021, the D.C. Circuit granted the motion to stay the CT Plan order and to expedite the appeal and established a briefing schedule. Briefing concluded in January 2022 and oral argument is scheduled for March 24, 2022. ​ The new CT Plan approved by the SEC may cause the Company’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or challenge such new consolidated data plan and it may have a material impact on our business, financial condition and operating results if, for example, there is a negative impact on the applicable market data revenues that we receive that are generated from such new plan. ​ Market Data Infrastructure Final Rule ​ On December 9, 2020, the SEC issued a Market Data Infrastructure Final Rule (“Final Rule”), which makes significant additions to the content available on the Securities Information Processors (“SIPs”) and replaces the exclusive processors with a competing consolidator model. The Final Rule is limited to market data disseminated by the equities SIPs and does not apply to proprietary market data, or the dissemination of options market data through OPRA. ​ On February 5, 2021, the Company filed a Petition for Review (the “2/5 PFR”) with the Court of Appeals for the D.C. Circuit challenging the Final Order. Additionally, on February 5, 2021, the Company filed a motion for stay of the Final Rule with the SEC, which the SEC denied on March 24, 2021. ​ On March 24, 2021, the SEC filed a Motion to Dismiss (“MTD”) with the D.C. Circuit: (1) arguing that the PFR is not ripe because the Final Rule had not been published in the Federal Register (“FR”), (2) suggesting (if there is ambiguity) that the D.C. Circuit clarify whether publication in the FR opens the filing window, and (3) suggesting that the D.C. Circuit could hold the case in abeyance pending filing of a PFR after publication in the FR. ​ On April 9, 2021, the Final Rule was published in the FR. On April 13, 2021, the Company filed another PFR (the “4/ PFR””) as a protective measure in the event the D.C. Circuit determined that the time to file a PFR does not commence until publication of the Final Rule in the FR. ​ On June 15, 2021, the D.C. Circuit entered an order granting the SEC’s MTD respecting the 2/5 PFR. This order does not affect the 4/13 PFR, which was filed after publication of the Final Rule in the FR on April 9, 2021. On July 9, 2021, the D.C. Circuit entered a briefing schedule, which concluded in January 2022. Oral argument is scheduled for March 18, 2022. ​ The implementation of the Final Rule could cause Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with or to challenge the new rules and they may have a material impact on our 54 Table of Contents business, financial condition and operating results if, for example, there are lower SIP plan revenues or we must reduce the fees we charge for market data. The Company intends to litigate the matter vigorously. ​ Item 4.Mine Safety Disclosures Not applicable. PART II Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Common Stock The Company’s common stock is listed on Cboe BZX under the trading symbol CBOE. As of January 31, 2022, there were approximately 123 holders of record of our common stock. Dividends Each share of common stock, including restricted stock awards and restricted stock units, is entitled to receive dividend and dividend equivalents, respectively, if, as and when declared by the Board of Directors of the Company. The Company’s expectation is to continue to pay dividends. The decision to pay a dividend, however, remains within the discretion of the Company's Board of Directors and may be affected by various factors, including our earnings, financial condition, capital requirements, level of indebtedness and other considerations our Board of Directors deems relevant. Future debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, our ability to pay dividends. As a holding company, the Company’s ability to declare and continue to pay dividends in the future with respect to its common stock will also be dependent upon the ability of its subsidiaries to pay dividends to it under applicable corporate law. Recent Sales of Unregistered Securities Not applicable. Use of Proceeds Not applicable. Purchases of Equity Securities by the Issuer and Affiliated Purchasers Share Repurchase Program In 2011, the Board of Directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and approved additional authorizations of $100 million in each of 2012, 2013, 2014, 2015 and 2016, $250 million in each of 2018, 2019 and 2020, and $200 million in February 2021, for a total authorization of $1.6 billion. The program permits the Company to purchase shares through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation. Under the program, for the year ended December 31, 2021, the Company repurchased 822,005 shares of common stock at an average cost per share of $98.82, totaling $81.3 million. Since inception of the program through December 31, 2021, the Company has repurchased 18,072,129 shares of common stock at an average cost per share of $68.12, totaling $1.2 billion.

Since its launch, Cboe LIS has grown to become one of the largest block-trading platforms in Europe. BIDS Trading’s proven block-trading capability provides the Company a foothold in the off-exchange segment of the U.S. equities market.

Components of Cost of Revenues Liquidity Payments Liquidity payments are directly correlated to the volume of securities traded on our markets. As stated above, we record the liquidity rebates paid to market participants providing liquidity, in the case of C2, BZX, EDGX, and Cboe Europe, Limited, as cost of revenue. BYX and EDGA offer a pricing model pursuant to whichwhere we rebate liquidity takers for executing against an order resting on our book, which is also recorded as a cost of revenue.revenues. Routing and Clearing Various rules require that U.S. options and equities trade executions occur at the National Best Bid/Offer (“NBBO”)NBBO displayed by any exchange. Linkage order routing consists of the cost incurred to provide a service whereby Cboe equities and options exchanges deliver orders to other execution venues when there is a potential for obtaining a better execution price or when instructed to directly route an order to another venue by the order provider. The service affords exchange order flow providers an opportunity to obtain the best available execution price and may also result in cost 52 Table of Contents benefits to those clients. Such an offering improves our competitive position and provides an opportunity to attract orders which would otherwise bypass our exchanges.

Since the regulatory transaction fees recorded in revenues are equal to the Section 31 fees recorded in cost of revenues, there is no impact on our operating income. CFE, Cboe Europe, LimitedCboe NL, BIDS, MATCHNow, Cboe FX, Cboe Australia and Cboe FXJapan are not U.S. national securities exchanges, and accordingly are not charged Section 31 fees. 62 Table of Contents Royalty Fees Royalty fees primarily consist of license fees paid by us for the use of underlying indices in our proprietary products usually based on contracts traded.

The Company is committed to operating a trusted, inclusive global marketplace, providing leading products, technology and data solutions that enable participants to define a sustainable financial future. Cboe provides trading solutions and products in multiple asset classes, including equities, derivatives and FX, across North America, Europe, and Asia Pacific. Cboe’s subsidiaries include the largest options exchange and the third largest stock exchange operator in the U.S. In addition, the Company operates one of the largest stock exchanges by value traded in Europe, and owns EuroCCP, a leading pan-European equities and derivatives clearinghouse, BIDS Trading, a leading block-trading ATS by volume in the U.S., MATCHNow, a leading equities ATS in Canada, and Cboe Australia, an operator of trading venues in Australia, and Cboe Japan, an operator of trading venues in Japan. Cboe also is a leading market globally for exchange-traded products (“ETPs”) listings and trading.

BIDS Holdings owns BIDS Trading, a registered broker-dealer and the operator of the BIDS ATS, the largest block-trading ATS by volume in the U.S. The BIDS ATS is not a registered national securities exchange or a facility thereof. The acquisition follows Cboe and BIDS Trading’s successful partnership in Europe, which began in 2016 with the creation of Cboe LIS for European equities block-trading. Since its launch, Cboe LIS has grown to become one of the largest block-trading platforms in Europe. BIDS Trading’s proven block-trading capability provides the Company a foothold in the off-exchange segment of the U.S. equities market. Additionally, BIDS Trading’s differentiated network of global buy-side investment managers and sell-side constituents provides the foundation for Cboe to potentially build more off-exchange products and services in non-U.S. equities or options products and in geographies beyond the U.S. Acquisition of Chi-X Asia Pacific On July 1, 2021, the Company completed the acquisition of Chi-X Asia Pacific Holdings, Ltd., a holding company of alternative market operators and providers of innovative market solutions. This acquisition provides the Company with a single point of entry into two key capital markets, Australia and Japan, helps enable it to expand its global equities and market data business into the Asia Pacific region, bring other products and services to the region, and further expand access to its unique proprietary product suite in the region. The transaction closed on July 1, 2021 based upon the time zone of both the acquiree, Chi-X Asia Pacific, and the acquiror, Cboe Worldwide Holdings Limited, a subsidiary of the Company. Investment in Trading Technologies On October 31, 2021, the Company, through a wholly-owned subsidiary, became a limited partner of 7Ridge Investments 3 LP (“7Ridge Fund”) in connection with 7Ridge Fund’s planned acquisition of Trading Technologies International, Inc.

ErisX operates a U.S.-based digital asset spot market, a regulated futures exchange and a regulated clearinghouse. Ownership of ErisX presents a unique opportunity for the Company to enter the digital asset spot and derivatives marketplaces through a digital-first platform developed with industry partners to focus on robust regulatory compliance, data and transparency. The transaction is expected to close in the first half of 2022; subject to regulatory review and other customary closing conditions. Planned acquisition of NEO On November 15, 2021, the Company announced it entered into a definitive agreement to acquire Aequitas Innovations, Inc. (“NEO”).

Ownership of NEO will help allow the Company to provide a more fulsome Canadian equities offering, operating the NEO Exchange, a national securities exchange with trading, listings, and other services, in addition to MATCHNow, the ATS acquired by the Company in 2020. The transaction is expected to close in the first half of 2022; subject to regulatory review and other customary closing conditions. Business Segments The Company reports five business segments: Options, North American Equities, Europe and Asia Pacific, Futures, and Global FX. Segment performance is primarily based on operating income (loss). The Company has aggregated all of its corporate costs and eliminations, as well as other business ventures, within Corporate Items and Eliminations; 59 Table of Contents however, operating expenses that relate to activities of a specific segment have been allocated to that segment. Our management allocates resources, assesses performance and manages our business according to these segments: Options. The Options segment includes options on market indices (“index options”), as well as on the stocks of individual corporations (“equity options”), and options on ETPs, such as exchange-traded funds (“ETFs”) and exchange-traded notes (“ETNs”), which are “multi-listed” options and listed on a non-exclusive basis. These options are eligible to trade on Cboe Options, C2, BZX, EDGX, and other U.S. national security exchanges. Cboe Options is the Company’s primary options market and offers trading in listed options through a single system that integrates electronic trading and traditional open outcry trading on the Cboe Options trading floor in Chicago. C2 Options, BZX Options, and EDGX Options are all-electronic options exchanges, and typically operate with different market models and fee structures than Cboe Options. The Options segment also includes applicable market data revenue generated from the consolidated tape plans, the licensing of proprietary options market data, index licensing, and access and capacity services. North American Equities. The North American Equities segment includes listed U.S. equities and ETP transaction services that occur on fully electronic exchanges owned and operated by BZX, BYX, EDGX, and EDGA, equities transactions that occur on the BIDS Trading platform, and Canadian equities and other transaction services that occur on or through the MATCHNow ATS. The North American Equities segment also includes ETP listings on BZX, the Cboe Global Markets, Inc. common stock listing, applicable market data revenue generated from the consolidated tape plans, the licensing of proprietary equities market data, routing services, and access and capacity services. Europe and Asia Pacific. The Europe and Asia Pacific segment includes the pan-European listed equities and derivatives transaction services, ETPs, exchange-traded commodities, and international depository receipts that are hosted on MTFs operated by Cboe Europe Equities (Cboe Europe and Cboe NL) and Cboe Europe Derivatives (“CEDX”). It also includes the ETP listings business on RMs and clearing activities of EuroCCP, as well as the equities transaction services of Cboe Australia and Cboe Japan, each operators of trading venues in Australia and Japan. This segment was previously referred to as the European Equities segment but was updated to the Europe segment in the first quarter of 2021 as a result of the launch of Cboe Europe Derivatives, a pan-European derivatives platform in September 2021. The segment was subsequently updated to Europe and Asia Pacific to reflect the acquisition of Chi-X Asia Pacific in July 2021. Cboe Europe operates lit and dark books, a periodic auctions book, and a Large-in-Scale (“LIS”) trading negotiation facility for UK symbols. Cboe NL, launched in October 2019 and based in Amsterdam, operates similar business functionality to that offered by Cboe Europe, and provides for trading only in European Economic Area (“EEA”) symbols. The new Cboe Europe Derivatives venue offers futures and options based on Cboe Europe equity indices. This segment also includes Cboe Europe, Cboe NL, CEDX, Cboe Australia, and Cboe Japan revenue generated from the licensing of proprietary market data and from access and capacity services. Futures. The Futures segment includes transaction services provided by the Company’s fully electronic futures exchange, CFE, which includes offerings for trading of VIX futures and other futures products, the licensing of proprietary market data, as well as access and capacity services.

General Factors Affecting Results of Operations In broad terms, our business performance is impacted by a number of drivers, including macroeconomic events affecting the risk and return of financial assets, investor sentiment, the regulatory environment for capital markets, geopolitical events, tax policies, central bank policies and changing technology, particularly in the financial services industry. We believe our future revenues and net income will continue to be influenced by a number of domestic and international economic trends, including: ​ ● trading volumes on our proprietary products such as VIX options and futures and SPX options; ● trading volumes in listed equity securities, options, futures, and ETPs in North America, Europe, and Asia Pacific, clearing volumes in listed equity securities and ETPs in Europe, volumes in listed equity options, and volumes in institutional FX trading; ● the demand for and pricing structure of the year ended December 31, 2019 compared toU.S. tape plan market data distributed by the same period in 2018, due to a decline in amortization underSecurities Information Processors (“SIPs”), which determines the discounted cash flow method forpool size of the intangibles acquiredindustry market data revenue we receive based on our market share; ● consolidation and expansion of our customers and competitors in the Bats acquisition, as well as a change in the accounting classification for the Chicago headquarters building to held for sale, which resulted in depreciation ceasing on the building.

Travel and Promotional Expenses Travel and promotional expenses decreased for the year ended December 31, 2019 compared to the same period in 2018, primarily due to a $0.7 million reduction in travel expenses and a reduction in marketing expenses of $0.2 million. 63industry; 60 Table of Contents Facilities Costs Facilities costs decreased ● the demand for information about, or access to, our markets and products, which is dependent on the year ended December 31, 2019 compared toproducts we trade, our importance as a liquidity center, quality and integrity of our proprietary indices, and the same periodquality and pricing of our data and access and capacity services; ● continuing pressure in 2018, primarilytransaction fee pricing due to a $1.2 million decline in rent expense and a $0.5 million decline in repairs and maintenance expense, partially offset by a $0.5 million increase in real estate taxes and a $0.3 million increase in utilities expenses. Acquisition-Related Costs Acquisition-related costs increased for the year ended December 31, 2019 compared to the same period in 2018, primarily due to an increase in severance costs, impairment charges recorded, which included the write down of goodwill attributed to a 2016 acquisition, a loss on disposal of data processing software recordedintense competition in the fourth quarterNorth American, European, and Asia Pacific markets; ● significant fluctuations in foreign currency translation rates or weakened value of 2019,currencies; and the write down ● regulatory changes and obligations relating to market structure and increased capital requirements, and those which affect certain types of the Chicago headquarters location attributed to the reduction in employee workspace needed in Chicago as a result of the Bats acquisition. Acquisition-related costs include fees for investment banking advisors, lawyers, accountants, tax advisors, public relations firms, severance and retention costs, impairment of goodwill, capitalized software and facilities, and other external costs directly related to the mergers and acquisitions, as well as compensation-related expenses. Other Expenses Other expenses increased for the year ended December 31, 2019 compared to the same period in 2018, primarily due to a $23.4 million provision for the notes receivable recorded in the fourth quarter of 2019 as a result of circumstances associated with the development of the consolidated audit trail. Operating Income As a result of the items above, operating income for the year ended December 31, 2019 was $537.2 million, compared to $599.4 million for the year ended December 31, 2018, a decrease of $62.2 million,instruments, transactions, products, pricing structures, capital market participants or 10.4%.

Other Income, Net Net other income decreased in the year ended December 31, 2019 compared to the same period in 2018 due to the reversal of the $8.8 million OCC dividend declared in 2018, which was to be paid in 2019, as a result of the SEC’s disapproval of the prior OCC capital plan during the first quarter of 2019. Income Before Income Tax Provision As a result of the above, income before income tax provision for the year ended December 31, 2019 was $501.4 million compared to $571.2 million for the year ended December 31, 2018, a decrease of $69.8 million,reporting or 12.2%.compliance requirements.

The effective tax rate for the year ended December 31, 2019 was 26.0%, compared to a rate of 25.6% for the year ended December 31, 2018. 64 Table of Contents Net Income As a result of the items above, net income for the year ended December 31, 2019 was $370.8 million, or 32.6% of revenues less cost of revenues, compared to $425.2 million, or 34.9% of revenues less cost of revenues, for the year ended December 31, 2018, a decrease of $54.4 million, or 12.8%. Segment Operating Results We report results from our five segments: Options, U.S. Equities, Futures, European Equities, and Global FX. Segment performance is primarily based on operating income (loss). We have aggregated all corporate costs, as well as other business ventures, within the Corporate Items and Eliminations as those activities should not be used to evaluate a segment's operating performance. All operating expenses that relate to activities of a specific segment have been allocated to that A number of significant structural, political and monetary issues and the COVID-19 pandemic continue to confront the global economy, and instability could continue, resulting in an increased or subdued level of inflation, market volatility, supply chain constraints, changes in trading volumes and greater uncertainty. Inflationary increases in our expenses, such as compensation inflation, may have an adverse effect on our financial results. We continue to closely monitor developments around COVID-19 and follow guidance provided by governmental and public health agencies. In response to COVID-19, we have provided frequent communications to employees, customers, regulators, critical vendors, technology equipment suppliers, data and disaster recovery centers, and other service providers and instructed non-essential employees to work from home on a temporary basis, implemented travel restrictions, and temporarily suspended open outcry trading between March 13, 2020 and June 14, 2020, without any known significant disruptions to our business or control processes. We expect to continue to take further actions as necessary in response to addressing COVID-19. Our business and operations could be materially and adversely affected by the effects of COVID-19, however, the extent to which our results could be affected by COVID-19 largely depends on future developments which cannot be accurately predicted and are uncertain. Further, changes in trading behavior, additional suspensions of open outcry trading, market disruptions and other future developments caused by the effects of COVID-19 could impact trading volumes and the demand for our products, market data, and services, which could have a material adverse effect on our business, financial condition, operating results and cash flows for fiscal year 2021 and could be material during any future period impacted either directly or indirectly by this pandemic. Components of Revenues Transaction and Clearing Fees Transaction fees represent fees charged by the Company for the performance obligation of executing a trade on its markets. These fees can be variable based on trade volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis. Transaction fees are recognized across all segments. Clearing fees, which include settlement fees, are charged by the Company for transactions cleared and settled by EuroCCP. Clearing fees can be variable based on trade volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis. Clearing fees are recognized in the Europe and Asia Pacific segment. Transaction and clearing fees, as well as any tiered volume discounts, are calculated and billed monthly in accordance with the Company’s published fee schedules. Access and Capacity Fees Access and capacity fees represent fees assessed for the opportunity to trade, including fees for trading-related functionality across all segments, terminal and other equipment rights, maintenance services, trading floor space and telecommunications services. Facilities, systems services and other fees are generally monthly fee-based. These fees are billed monthly in accordance with the Company’s published fee schedules and recognized on a monthly basis when the performance obligation is met. All access and capacity fees associated with the trading floor are recognized in the Options segment. There is no remaining performance obligation after revenue is recognized. Market Data Fees Market data fees represent the fees from the U.S. tape plans and fees from customers for proprietary market data. Fees from the U.S. tape plans are collected monthly based on published fee schedules and distributed quarterly to the Exchanges based on a known formula using trading and/or quoting activity. A contract for proprietary market data is entered into and charged on a monthly basis in accordance with the Company’s published fee schedules as the service is provided. Both types of market data are satisfied over time, and revenue is recognized on a monthly basis as the customer receives and consumes the benefit as the Company provides the data. U.S. tape plan market data is 61 Table of Contents recognized in the North American Equities and Options segments. Proprietary market data fees are recognized across all segments. Regulatory Fees Regulatory fees primarily represent fees collected by the Company to cover the Section 31 fees charged to the Exchanges under the authority of the SEC (Cboe Options, C2, BZX, BYX, EDGX, and EDGA) and are charged by the SEC. Consistent with industry practice, the fees charged to customers are based on the fee set by the SEC per notional value of U.S. Equities exchange transactions and per round turn of Options transactions executed on the Company’s U.S. securities markets. These fees are calculated and billed monthly and are recognized in the North American Equities and Options segments. As the Exchanges are responsible for the ultimate payment to the SEC, the Exchanges are considered the principals in these transactions. Regulatory fees also include the options regulatory fee (“ORF”) which supports the Company’s regulatory oversight function in the Options segment, along with other miscellaneous regulatory fees, and neither can be used for non-regulatory purposes. The ORF and miscellaneous fees are recognized when the performance obligation is fulfilled. Other Revenue Other revenue primarily consists of revenue from various licensing agreements, interest income from clearing operations, all fees related to the trade reporting facility operated in the Europe and Asia Pacific segment, and listing fees. Components of Cost of Revenues Liquidity Payments Liquidity payments are directly correlated to the volume of securities traded on our markets. As stated above, we record the liquidity rebates paid to market participants providing liquidity, in the case of C2, BZX, EDGX, and Cboe Europe, as cost of revenue. BYX and EDGA offer a pricing model where we rebate liquidity takers for executing against an order resting on our book, which is also recorded as a cost of revenues. Routing and Clearing Various rules require that U.S. options and equities trade executions occur at the NBBO displayed by any exchange. Linkage order routing consists of the cost incurred to provide a service whereby Cboe equities and options exchanges deliver orders to other execution venues when there is a potential for obtaining a better execution price or when instructed to directly route an order to another venue by the order provider. The service affords exchange order flow providers an opportunity to obtain the best available execution price and may also result in cost benefits to those clients. Such an offering improves our competitive position and provides an opportunity to attract orders which would otherwise bypass our exchanges. We utilize third-party brokers or our broker-dealer, Cboe Trading, to facilitate such delivery. Also included within routing and clearing are the Order Management System and Execution Management System (“OMS” and “EMS”, respectively) fees incurred for U.S. Equities Off-Exchange order execution, as well as settlement costs incurred for the settlement process executed by EuroCCP. Section 31 Fees Exchanges under the authority of the SEC (Cboe Options, C2, BZX, BYX, EDGX, and EDGA) are assessed fees pursuant to the Exchange Act designed to recover the costs to the U.S. government of supervision and regulation of securities markets and securities professionals. We treat these fees as a pass-through charge to customers executing eligible listed equities and listed equity options trades. Accordingly, we recognize the amount that we are charged under Section 31 as a cost of revenues and the corresponding amount that we charge our customers as regulatory transaction fees revenue. Since the regulatory transaction fees recorded in revenues are equal to the Section 31 fees recorded in cost of revenues, there is no impact on our operating income. CFE, Cboe Europe, Cboe NL, BIDS, MATCHNow, Cboe FX, Cboe Australia and Cboe Japan are not U.S. national securities exchanges, and accordingly are not charged Section 31 fees. 62 Table of Contents Royalty Fees Royalty fees primarily consist of license fees paid by us for the use of underlying indices in our proprietary products usually based on contracts traded. The Company has licenses with the owners of the S&P 500 Index, S&P 100 Index and certain other S&P indices, FTSE Russell indices, the DJIA, MSCI, and certain other index products. This category also includes fees related to the dissemination of market data related to S&P indices and other products through Cboe Streaming Market Indices (“CSMI”). Other Cost of Revenues Other cost of revenues primarily consists of interest expense from clearing operations, electronic access permit fees and other miscellaneous costs associated with other revenue. Components of Operating Expenses Compensation and Benefits Compensation and benefits represent our largest expense category and tend to be driven by our staffing requirements, financial performance, and the general dynamics of the employment market. Stock-based compensation is a non-cash expense related to equity awards. Stock-based compensation can vary depending on the quantity and fair value of the award on the date of grant and the related service period. Depreciation and Amortization Depreciation and amortization expense results from the depreciation of long-lived assets purchased, the amortization of purchased and internally developed software, and the amortization of intangible assets. Technology Support Services Technology support services consists primarily of costs related to the maintenance of computer equipment supporting our system architecture, circuits supporting our wide area network, support for production software, operating system license and support fees, fees paid to information vendors for displaying data and off-site system hosting fees. Professional Fees and Outside Services Professional fees and outside services consist primarily of consulting services, which include supplemental staff activities primarily related to systems development and maintenance, legal, regulatory and audit, and tax advisory services. Travel and Promotional Expenses Travel and promotional expenses primarily consist of advertising, costs for special events, sponsorship of industry conferences, options education seminars and travel-related expenses. Facilities Costs Facilities costs primarily consist of expenses related to owned and leased properties including rent, maintenance, utilities, real estate taxes and telecommunications costs. Acquisition-Related Costs Acquisition-related costs relate to acquisitions and other strategic opportunities, including the Merger. The acquisition-related costs include fees for investment banking advisors, lawyers, accountants, tax advisors, public relations firms, severance and retention costs, impairment of goodwill, capitalized software and facilities, and other external costs directly related to the mergers and acquisitions. 63 Table of Contents Other Expenses Other expenses represent costs necessary to support our operations that are not already included in the above categories. Non-Operating (Expenses) Income Income and expenses incurred through activities outside of our core operations are considered non-operating and are classified as other (expense) income. These activities primarily include interest earned on the investing of excess cash, interest expense related to outstanding debt facilities, dividend income, income and unrealized gains and losses related to investments held in a trust for the Company’s non-qualified retirement and benefit plans, and equity earnings or losses from our investments in other business ventures. RESULTS OF OPERATIONS The following are summaries of changes in financial performance and include certain non-GAAP financial measures. Management uses these non-GAAP measures internally in conjunction with GAAP measures to help evaluate our performance and to help make financial and operational decisions. These non-GAAP financial measures assist management in comparing our performance on a consistent basis for purposes of business decision making by removing the impact of certain items management believes do not reflect our underlying operations. We believe our presentation of these measures provides investors with greater transparency into financial measures used by management and is useful to investors for period-to-period comparisons of our ongoing operating performance.   These non-GAAP financial measures are not presented in accordance with, or as an alternative to, GAAP financial measures and may be calculated differently from non-GAAP measures used by other companies, which reduces their usefulness as comparative measures. We encourage analysts, investors and other interested parties to use these non-GAAP measures as supplemental information to the GAAP financial measures included herein, including our consolidated financial statements, to enhance their analysis and understanding of our performance and in making comparisons. Please see the footnotes below for definitions, additional information, and reconciliations from the closest GAAP measure. ​ 64 Table of Contents Comparison of Years Ended December 31, 2021 and 2020 Overview The following summarizes changes in financial performance for the year ended December 31, 2021, compared to the year ended December 31, 2020: ​ (1) These are Non-GAAP figures for which reconciliations are provided below (in millions, except percentages, earnings per share, and as noted below). ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended      ​ ​      ​   ​ ​ December 31, ​ Increase/ ​ Percent   ​      2021      2020      (Decrease)      Change   Total revenues ​ $ 3,494.8 ​ $ 3,427.1 ​ $ 67.7 ​ 2 % Total cost of revenues   ​ 2,018.7   ​ 2,172.8   ​ (154.1)   (7) % Revenues less cost of revenues   ​ 1,476.1   ​ 1,254.3   ​ 221.8   18 % Total operating expenses   ​ 670.2   ​ 592.1   ​ 78.1   13 % Operating income   ​ 805.9   ​ 662.2   ​ 143.7   22 % Income before income tax provision   ​ 756.1   ​ 660.4   ​ 95.7   14 % Income tax provision   ​ 227.1   ​ 192.2   ​ 34.9   18 % Net income ​ $ 529.0 ​ $ 468.2 ​ $ 60.8   13 % Basic earnings per share ​ $ 4.93 ​ $ 4.28 ​ $ 0.65 ​ 15 % Diluted earnings per share ​ ​ 4.92 ​ ​ 4.27 ​ ​ 0.65 ​ 15 % Organic net revenue (1) ​ $ 1,393.3 ​ $ 1,254.3 ​ $ 139.0 ​ 11 % EBITDA (2) ​ $ 969.2 ​ $ 855.3 ​ $ 113.9   13 % EBITDA margin (3) ​   65.7 %     68.2 %     (2.5) %       * Adjusted EBITDA (2) ​ $ 987.1 ​ $ 874.6 ​ $ 112.5   13 % Adjusted EBITDA margin (4) ​   66.9 %     69.7 %     (2.8) %       * Adjusted earnings (5) ​ $ 648.8 ​ $ 576.5 ​ $ 72.3   13 % Adjusted earnings margin (5) ​ ​ 44.0 %   ​ 46.0 %   ​ (2.0) %   ​ * Diluted weighted average shares outstanding ​ ​ 107.2 ​ ​ 109.3 ​ ​ (2.1) ​ (2) % Adjusted Diluted earnings per share (6) ​ $ 6.05 ​ $ 5.27 ​ $ 0.78   15 % * Not meaningful 65 Table of Contents The following summarizes our total revenues by segment: (1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Percentage of   ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total   ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues   ​ ​ Year Ended ​ ​ ​ Year Ended   ​ ​ December 31, ​ Percent ​ December 31,   ​      2019      2018      Change      2019      2018   ​ ​ (in millions, except percentages) ​ Options ​ $ 983.1 ​ $ 1,057.5 ​ (7.0) %   39.4 %   38.2 %   U.S. Equities ​   1,213.1 ​   1,373.1 ​ (11.7) %   48.6 % 49.6 % Futures ​   135.9 ​   149.8 ​ (9.3) %   5.4 % 5.4 % European Equities ​   110.8 ​   131.6 ​ (15.8) %   4.4 % 4.8 % Global FX ​ ​ 53.0 ​ ​ 56.4 ​ (6.0) %   2.1 % 2.0 % Corporate ​ ​ 0.2 ​ ​ 0.4 ​ (50.0) %   — % — % Total revenues ​ $ 2,496.1 ​ $ 2,768.8 ​ (9.8) %   100.0 % 100.0 % ​ 66 Table of Contents The following summarizes ourOrganic net revenue is defined as revenues less cost of revenues by segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Percentage of   ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Revenues   ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ less Cost of Revenues   ​ ​ Year Ended ​ ​ ​ Year Ended   ​ ​ December 31, ​ Percent ​ December 31,   ​      2019      2018      Change      2019      2018   ​ ​ (in millions, except percentages) ​ Options ​ $ 564.1 ​ $ 611.2 ​ (7.7) %   49.6 %   50.2 %   U.S. Equities ​   300.8 ​   310.2 ​ (3.0) %   26.5 % 25.6 % Futures ​   131.3 ​   144.1 ​ (8.9) %   11.5 % 11.8 % European Equities ​   87.5 ​   94.6 ​ (7.5) %   7.7 % 7.8 % Global FX ​ ​ 53.0 ​ ​ 56.4 ​ (6.0) %   4.7 % 4.6 % Corporate ​ ​ 0.2 ​ ​ 0.4 ​ (50.0) %   — % — % Total revenues less cost of revenues ​ $ 1,136.9 ​ $ 1,216.9 ​ (6.6) %   100.0 % 100.0 % ​ 67 Table of Contents Options The following summarizesexcluding revenues less cost of revenues of any acquisition that has been owned for less than one year. Revenues from acquisitions that have been owned at least one year are considered organic and are no longer excluded from organic net revenue from either period for comparative purposes. Organic net revenue does not represent, and should not be considered as, an alternative to revenues less cost of revenues, or net revenue, as determined in accordance with GAAP. We have presented organic net revenue because we consider it an important supplemental measure of our performance and we use it as the basis for monitoring our operating expenses, operatingfinancial performance before the effects of acquisitions. We also believe that it is frequently used by analysts, investors and other interested parties in the evaluation of companies. We believe that investors may find this non-GAAP measure useful in evaluating our performance compared to that of peer companies in our industry. Other companies may calculate organic net revenue differently than we do. Organic net revenue has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. ​ ​ ​ ​ ​ ​ ​ ​ Year Ended   ​ December 31,   ​ 2021 ​ 2020 ​ Revenues less cost of revenues $ 1,476.1 ​ $ 1,254.3 ​ Recent acquisitions: ​ ​ ​ ​ ​ ​ Acquisition revenues less cost of revenues $ (82.8) ​ $ — ​ Organic net revenue $ 1,393.3 ​ $ 1,254.3 ​ ​ (2) EBITDA is defined as income before interest, income taxes, depreciation and amortization.

Other companies may calculate EBITDA and adjusted EBITDA differently than we do. EBITDA and adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP. (3) EBITDA margin represents EBITDA divided by revenues less cost of revenues. Revenue less cost of revenues decreased $47.1 million for the year ended December 31, 2019 compared to the year ended December 31, 2018, primarily due to a 5.4% decrease in overall options market ADV, including a 13.6% decrease in index options ADV. For the year ended December 31, 2019, the operating income decreased $56.6 million compared to the year ended December 31, 2018 due to lower revenues less cost of revenues. Operating expenses increased $9.5 million for the year ended December 31, 2019, compared to the prior period, primarily due to the provision for notes receivable related to circumstances associated with the development of the consolidated audit trail recorded in the fourth quarter of 2019, coupled with increases in acquisition-related costs and higher compensation and benefits as a result of higher cost allocations and the loss on disposal of data processing software due to the migration of Cboe Options to the Bats technology platform in 2019, partially offset by a decrease in depreciation and amortization.

For the year ended December 31, 2019, the U.S. Equities segment's operating income decreased $8.0 million compared to the year ended December 31, 2018 as a result of lower revenues less cost of revenues. Operating expenses remained flat for the year ended December 31, 2019 compared to the year ended December 31, 2018, primarily due to thepurchased intangibles, acquisition-related costs, provision for notes receivable, relatedbargain purchase gain, impairment of investment, change in contingent consideration, release of tax reserves, deferred tax re-measurements, and net income allocated to circumstances associated with the developmentparticipating securities, net of the consolidated audit trail recordedincome tax effects of these adjustments. Adjusted earnings does not represent, and should not be considered as, an alternative to net income, as determined in accordance with GAAP. We have presented adjusted earnings because we consider it an important supplemental measure of our performance and we use it as the basis for monitoring our own core operating financial performance relative to other operators of exchanges. We also believe that it is frequently used by analysts, investors and other interested parties in the fourth quarterevaluation of 2019, offsetcompanies. We believe that investors may find this non-GAAP measure useful in evaluating our performance compared to that of peer companies in our industry. Other companies may calculate adjusted earnings differently than we do. Adjusted earnings has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP.

BIDS Holdings owns BIDS Trading, a registered broker-dealer and the operator of the BIDS ATS, the largest block-trading ATS by volume in the U.S. The BIDS ATS is not a registered national securities exchange or a facility thereof. The acquisition follows Cboe and BIDS Trading’s successful partnership in Europe, which began in 2016 with the creation of Cboe LIS for European equities block-trading. Since its launch, Cboe LIS has grown to become one of the largest block-trading platforms in Europe.

The transaction is expected to close in the first half of 2022; subject to regulatory review and other customary closing conditions. Business Segments The Company reports five business segments: Options, North American Equities, Europe and Asia Pacific, Futures, and Global FX. Segment performance is primarily based on operating income (loss). The Company has aggregated all of its corporate costs and eliminations, as well as other business ventures, within Corporate Items and Eliminations; 59 Table of Contents however, operating expenses that relate to activities of a specific segment have been allocated to that segment. Our management allocates resources, assesses performance and manages our business according to these segments: Options. The Options segment includes options on market indices (“index options”), as well as on the stocks of individual corporations (“equity options”), and options on ETPs, such as exchange-traded funds (“ETFs”) and exchange-traded notes (“ETNs”), which are “multi-listed” options and listed on a non-exclusive basis. These options are eligible to trade on Cboe Options, C2, BZX, EDGX, and other U.S. national security exchanges. Cboe Options is the Company’s primary options market and offers trading in listed options through a single system that integrates electronic trading and traditional open outcry trading on the Cboe Options trading floor in Chicago. C2 Options, BZX Options, and EDGX Options are all-electronic options exchanges, and typically operate with different market models and fee structures than Cboe Options. The Options segment also includes applicable market data revenue generated from the consolidated tape plans, the licensing of proprietary options market data, index licensing, and access and capacity services. North American Equities. The North American Equities segment includes listed U.S. equities and ETP transaction services that occur on fully electronic exchanges owned and operated by BZX, BYX, EDGX, and EDGA, equities transactions that occur on the BIDS Trading platform, and Canadian equities and other transaction services that occur on or through the MATCHNow ATS. The North American Equities segment also includes ETP listings on BZX, the Cboe Global Markets, Inc. common stock listing, applicable market data revenue generated from the consolidated tape plans, the licensing of proprietary equities market data, routing services, and access and capacity services. Europe and Asia Pacific. The Europe and Asia Pacific segment includes the pan-European listed equities and derivatives transaction services, ETPs, exchange-traded commodities, and international depository receipts that are hosted on MTFs operated by Cboe Europe Equities (Cboe Europe and Cboe NL) and Cboe Europe Derivatives (“CEDX”). It also includes the ETP listings business on RMs and clearing activities of EuroCCP, as well as the equities transaction services of Cboe Australia and Cboe Japan, each operators of trading venues in Australia and Japan. This segment was previously referred to as the European Equities segment but was updated to the Europe segment in the first quarter of 2021 as a result of the launch of Cboe Europe Derivatives, a pan-European derivatives platform in September 2021. The segment was subsequently updated to Europe and Asia Pacific to reflect the acquisition of Chi-X Asia Pacific in July 2021. Cboe Europe operates lit and dark books, a periodic auctions book, and a Large-in-Scale (“LIS”) trading negotiation facility for UK symbols. Cboe NL, launched in October 2019 and based in Amsterdam, operates similar business functionality to that offered by Cboe Europe, and provides for trading only in European Economic Area (“EEA”) symbols. The new Cboe Europe Derivatives venue offers futures and options based on Cboe Europe equity indices. This segment also includes Cboe Europe, Cboe NL, CEDX, Cboe Australia, and Cboe Japan revenue generated from the licensing of proprietary market data and from access and capacity services. Futures. The Futures segment includes transaction services provided by the Company’s fully electronic futures exchange, CFE, which includes offerings for trading of VIX futures and other futures products, the licensing of proprietary market data, as well as access and capacity services. Global FX. The Global FX segment includes institutional FX trading services that occur on the Cboe FX fully electronic trading platform, non-deliverable forward FX transactions (“NDFs”) offered for execution on Cboe SEF and Cboe Swiss, as well as revenue generated from the licensing of proprietary market data and from access and capacity services. General Factors Affecting Results of Operations In broad terms, our business performance is impacted by a number of drivers, including macroeconomic events affecting the risk and return of financial assets, investor sentiment, the regulatory environment for capital markets, geopolitical events, tax policies, central bank policies and changing technology, particularly in the financial services industry. We believe our future revenues and net income will continue to be influenced by a number of domestic and international economic trends, including: ​ ● trading volumes on our proprietary products such as VIX options and futures and SPX options; ● trading volumes in listed equity securities, options, futures, and ETPs in North America, Europe, and Asia Pacific, clearing volumes in listed equity securities and ETPs in Europe, volumes in listed equity options, and volumes in institutional FX trading; ● the demand for the foreseeable future. In the near term, we expect that our cash from operations and availability under our revolving credit facility will meet our cash needs to fund our operations, capital expenditures, interest payments on debt, debt repayments, any dividends, potential strategic acquisitions, and opportunities for common stock repurchases under the previously announced program. We may also utilize excess cash on hand to pay down amounts outstanding under the Term Loan Agreement. See Note 13 (“Debt”)pricing structure of the consolidated financial statements for further information.  Our long-term cash needs will dependU.S. tape plan market data distributed by the Securities Information Processors (“SIPs”), which determines the pool size of the industry market data revenue we receive based on many factors, including an introduction of new products, enhancements of current products, the geographic mixour market share; ● consolidation and expansion of our businesscustomers and any potential acquisitions. We believe our cash from operations andcompetitors in the availability under our revolving credit facility will meet any long-term needs unless a significant acquisition is identified, in which case we expect that we would be able to borrow the necessary funds to complete such an acquisition. In February 2020, we acquired Hanweck Associates, LLC (“Hanweck”), a real-time risk analytics company based in New York, and the business of FT Providers, LLC, a portfolio management platform provider based in Chicago, commonly referred to as FT Options (“FT”) with cash on hand. Cash and cash equivalents include cash in banks and all non-restricted, highly liquid investments with original maturities of three months or less at the time of purchase. Cash and cash equivalents as of December 31, 2019 decreased 71industry; 60 Table of Contents $45.8 million from December 31, 2018 primarily ● the demand for information about, or access to, our markets and products, which is dependent on the products we trade, our importance as a liquidity center, quality and integrity of our proprietary indices, and the quality and pricing of our data and access and capacity services; ● continuing pressure in transaction fee pricing due to share repurchases of $156.9 million and dividends of $150.0 million, offset by net income and other operating activities. See “Cash Flow” below for further discussion. Our cash and cash equivalents held outside of the United States in various foreign subsidiaries totaled $85.1 million and $72.9 million as of December 31, 2019 and December 31, 2018, respectively. The remaining balance was heldintense competition in the United StatesNorth American, European, and totaled $144.1 millionAsia Pacific markets; ● significant fluctuations in foreign currency translation rates or weakened value of currencies; and $202.2 million as ● regulatory changes and obligations relating to market structure and increased capital requirements, and those which affect certain types of December 31, 2019 and December 31, 2018, respectively. The majority of cash held outside the United States is available for repatriation, but under current law, could subject us to additional United States income taxes, less applicable foreign tax credits. Our financial investments include deferred compensation plan assets, as well as investments with originalinstruments, transactions, products, pricing structures, capital market participants or acquired maturities longer than three months but that mature in less than one year from the balance sheet date and are recorded at fair value. As of December 31, 2019 financial investments consisted of U.S. Treasury securities and deferredreporting or compliance requirements. A number of significant structural, political and monetary issues and the COVID-19 pandemic continue to confront the global economy, and instability could continue, resulting in an increased or subdued level of inflation, market volatility, supply chain constraints, changes in trading volumes and greater uncertainty. Inflationary increases in our expenses, such as compensation inflation, may have an adverse effect on our financial results. We continue to closely monitor developments around COVID-19 and follow guidance provided by governmental and public health agencies. In response to COVID-19, we have provided frequent communications to employees, customers, regulators, critical vendors, technology equipment suppliers, data and disaster recovery centers, and other service providers and instructed non-essential employees to work from home on a temporary basis, implemented travel restrictions, and temporarily suspended open outcry trading between March 13, 2020 and June 14, 2020, without any known significant disruptions to our business or control processes. We expect to continue to take further actions as necessary in response to addressing COVID-19. Our business and operations could be materially and adversely affected by the effects of COVID-19, however, the extent to which our results could be affected by COVID-19 largely depends on future developments which cannot be accurately predicted and are uncertain. Further, changes in trading behavior, additional suspensions of open outcry trading, market disruptions and other future developments caused by the effects of COVID-19 could impact trading volumes and the demand for our products, market data, and services, which could have a material adverse effect on our business, financial condition, operating results and cash flows for fiscal year 2021 and could be material during any future period impacted either directly or indirectly by this pandemic. Components of Revenues Transaction and Clearing Fees Transaction fees represent fees charged by the Company for the performance obligation of executing a trade on its markets. These fees can be variable based on trade volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis. Transaction fees are recognized across all segments. Clearing fees, which include settlement fees, are charged by the Company for transactions cleared and settled by EuroCCP. Clearing fees can be variable based on trade volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis. Clearing fees are recognized in the Europe and Asia Pacific segment. Transaction and clearing fees, as well as any tiered volume discounts, are calculated and billed monthly in accordance with the Company’s published fee schedules. Access and Capacity Fees Access and capacity fees represent fees assessed for the opportunity to trade, including fees for trading-related functionality across all segments, terminal and other equipment rights, maintenance services, trading floor space and telecommunications services. Facilities, systems services and other fees are generally monthly fee-based. These fees are billed monthly in accordance with the Company’s published fee schedules and recognized on a monthly basis when the performance obligation is met. All access and capacity fees associated with the trading floor are recognized in the Options segment. There is no remaining performance obligation after revenue is recognized. Market Data Fees Market data fees represent the fees from the U.S. tape plans and fees from customers for proprietary market data. Fees from the U.S. tape plans are collected monthly based on published fee schedules and distributed quarterly to the Exchanges based on a known formula using trading and/or quoting activity. A contract for proprietary market data is entered into and charged on a monthly basis in accordance with the Company’s published fee schedules as the service is provided. Both types of market data are satisfied over time, and revenue is recognized on a monthly basis as the customer receives and consumes the benefit as the Company provides the data. U.S. tape plan market data is 61 Table of Contents recognized in the North American Equities and Options segments. Proprietary market data fees are recognized across all segments. Regulatory Fees Regulatory fees primarily represent fees collected by the Company to cover the Section 31 fees charged to the Exchanges under the authority of the SEC (Cboe Options, C2, BZX, BYX, EDGX, and EDGA) and are charged by the SEC. Consistent with industry practice, the fees charged to customers are based on the fee set by the SEC per notional value of U.S. Equities exchange transactions and per round turn of Options transactions executed on the Company’s U.S. securities markets. These fees are calculated and billed monthly and are recognized in the North American Equities and Options segments. As the Exchanges are responsible for the ultimate payment to the SEC, the Exchanges are considered the principals in these transactions. Regulatory fees also include the options regulatory fee (“ORF”) which supports the Company’s regulatory oversight function in the Options segment, along with other miscellaneous regulatory fees, and neither can be used for non-regulatory purposes. The ORF and miscellaneous fees are recognized when the performance obligation is fulfilled. Other Revenue Other revenue primarily consists of revenue from various licensing agreements, interest income from clearing operations, all fees related to the trade reporting facility operated in the Europe and Asia Pacific segment, and listing fees. Components of Cost of Revenues Liquidity Payments Liquidity payments are directly correlated to the volume of securities traded on our markets. As stated above, we record the liquidity rebates paid to market participants providing liquidity, in the case of C2, BZX, EDGX, and Cboe Europe, as cost of revenue. BYX and EDGA offer a pricing model where we rebate liquidity takers for executing against an order resting on our book, which is also recorded as a cost of revenues. Routing and Clearing Various rules require that U.S. options and equities trade executions occur at the NBBO displayed by any exchange. Linkage order routing consists of the cost incurred to provide a service whereby Cboe equities and options exchanges deliver orders to other execution venues when there is a potential for obtaining a better execution price or when instructed to directly route an order to another venue by the order provider. The service affords exchange order flow providers an opportunity to obtain the best available execution price and may also result in cost benefits to those clients. Such an offering improves our competitive position and provides an opportunity to attract orders which would otherwise bypass our exchanges. We utilize third-party brokers or our broker-dealer, Cboe Trading, to facilitate such delivery. Also included within routing and clearing are the Order Management System and Execution Management System (“OMS” and “EMS”, respectively) fees incurred for U.S. Equities Off-Exchange order execution, as well as settlement costs incurred for the settlement process executed by EuroCCP. Section 31 Fees Exchanges under the authority of the SEC (Cboe Options, C2, BZX, BYX, EDGX, and EDGA) are assessed fees pursuant to the Exchange Act designed to recover the costs to the U.S. government of supervision and regulation of securities markets and securities professionals. We treat these fees as a pass-through charge to customers executing eligible listed equities and listed equity options trades. Accordingly, we recognize the amount that we are charged under Section 31 as a cost of revenues and the corresponding amount that we charge our customers as regulatory transaction fees revenue. Since the regulatory transaction fees recorded in revenues are equal to the Section 31 fees recorded in cost of revenues, there is no impact on our operating income. CFE, Cboe Europe, Cboe NL, BIDS, MATCHNow, Cboe FX, Cboe Australia and Cboe Japan are not U.S. national securities exchanges, and accordingly are not charged Section 31 fees. 62 Table of Contents Royalty Fees Royalty fees primarily consist of license fees paid by us for the use of underlying indices in our proprietary products usually based on contracts traded. The Company has licenses with the owners of the S&P 500 Index, S&P 100 Index and certain other S&P indices, FTSE Russell indices, the DJIA, MSCI, and certain other index products. This category also includes fees related to the dissemination of market data related to S&P indices and other products through Cboe Streaming Market Indices (“CSMI”). Other Cost of Revenues Other cost of revenues primarily consists of interest expense from clearing operations, electronic access permit fees and other miscellaneous costs associated with other revenue. Components of Operating Expenses Compensation and Benefits Compensation and benefits represent our largest expense category and tend to be driven by our staffing requirements, financial performance, and the general dynamics of the employment market. Stock-based compensation is a non-cash expense related to equity awards. Stock-based compensation can vary depending on the quantity and fair value of the award on the date of grant and the related service period. Depreciation and Amortization Depreciation and amortization expense results from the depreciation of long-lived assets purchased, the amortization of purchased and internally developed software, and the amortization of intangible assets. Technology Support Services Technology support services consists primarily of costs related to the maintenance of computer equipment supporting our system architecture, circuits supporting our wide area network, support for production software, operating system license and support fees, fees paid to information vendors for displaying data and off-site system hosting fees. Professional Fees and Outside Services Professional fees and outside services consist primarily of consulting services, which include supplemental staff activities primarily related to systems development and maintenance, legal, regulatory and audit, and tax advisory services. Travel and Promotional Expenses Travel and promotional expenses primarily consist of advertising, costs for special events, sponsorship of industry conferences, options education seminars and travel-related expenses. Facilities Costs Facilities costs primarily consist of expenses related to owned and leased properties including rent, maintenance, utilities, real estate taxes and telecommunications costs. Acquisition-Related Costs Acquisition-related costs relate to acquisitions and other strategic opportunities, including the Merger. The acquisition-related costs include fees for investment banking advisors, lawyers, accountants, tax advisors, public relations firms, severance and retention costs, impairment of goodwill, capitalized software and facilities, and other external costs directly related to the mergers and acquisitions. 63 Table of Contents Other Expenses Other expenses represent costs necessary to support our operations that are not already included in the above categories. Non-Operating (Expenses) Income Income and expenses incurred through activities outside of our core operations are considered non-operating and are classified as other (expense) income. These activities primarily include interest earned on the investing of excess cash, interest expense related to outstanding debt facilities, dividend income, income and unrealized gains and losses related to investments held in a trust for the Company’s non-qualified retirement and benefit plans, and equity earnings or losses from our investments in other business ventures. RESULTS OF OPERATIONS The following are summaries of changes in financial performance and include certain non-GAAP financial measures. Management uses these non-GAAP measures internally in conjunction with GAAP measures to help evaluate our performance and to help make financial and operational decisions. These non-GAAP financial measures assist management in comparing our performance on a consistent basis for purposes of business decision making by removing the impact of certain items management believes do not reflect our underlying operations. We believe our presentation of these measures provides investors with greater transparency into financial measures used by management and is useful to investors for period-to-period comparisons of our ongoing operating performance.   These non-GAAP financial measures are not presented in accordance with, or as an alternative to, GAAP financial measures and may be calculated differently from non-GAAP measures used by other companies, which reduces their usefulness as comparative measures. We encourage analysts, investors and other interested parties to use these non-GAAP measures as supplemental information to the GAAP financial measures included herein, including our consolidated financial statements, to enhance their analysis and understanding of our performance and in making comparisons. Please see the footnotes below for definitions, additional information, and reconciliations from the closest GAAP measure. ​ 64 Table of Contents Comparison of Years Ended December 31, 2021 and 2020 Overview The following summarizes changes in financial performance for the year ended December 31, 2021, compared to the year ended December 31, 2020: Cash Flow The following table summarizes our cash flow data for the years ended December 31, 2019, 2018 and 2017: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Year Ended   ​ ​ December 31,   ​      2019      2018      2017   ​ ​ (in millions)   Net cash provided by operating activities ​ $ 632.8 ​ $ 534.7 ​ $ 374.4 ​ Net cash used in investing activities ​   (15.9) ​   (25.6) ​   (1,436.5) ​ Net cash (used in) provided by financing activities ​   (662.9) ​   (371.6) ​   1,099.7 ​ Effect of foreign currency exchange rate changes on cash and cash equivalents ​   0.2 ​   (5.9) ​   8.6 ​ (Decrease) increase in cash and cash equivalents ​ $ (45.8) ​ $ 131.6 ​ $ 46.2 ​ ​ (1) Net Cash Flows Provided by Operating Activities During the year ended December 31, 2019, net cashThese are Non-GAAP figures for which reconciliations are provided by operating activities was $262.0 million higher than net income.

Net cash provided by operating activities was $632.8 million and $534.7 million for the years ended December 31, 2019 and 2018, respectively. The increase in net cash flows provided by operating activities was primarily due to decreases in accounts receivable and increases in income tax liability, and Section 31 fees payable, partially offset by the decline in net income. Net cash provided by operating activities was $109.5 million higher than net income for the fiscal year ended December 31, 2018.

Net cash provided by operating activities was $534.7 million and $374.4 million for the years ended December 31, 2018 and 2017, respectively. The increase in net cash flows provided by operating activities was primarily due to higher net income. Net Cash Flows Used in Investing Activities Net cash flows used in investing activities were $15.9 million and $25.6 million for the years ended December 31, 2019 and 2018, respectively.

Organic net revenue does not represent, and should not be considered as, an alternative to revenues less cost of available-for-sale investments, offsetrevenues, or net revenue, as determined in accordance with GAAP.

For the year ended December 31, 2019, the Company paid down $350.0 million of long-term debt, repurchased $156.9 million of common stock, and paid dividends totaling $150.0 million. Net cash flows used in financing activities totaled $371.6 million for the year ended December 31, 2018.

Purchase of common stock totaled $140.9 million, and dividends paid totaled $130.3 million. Net cash flows provided by financing activities totaled $1.1 billion for the year ended December 31, 2017. The $1.4 billion decrease in net cash flows provided by financing activities resulted primarily from proceeds from long-term debt not recurring in 2018.

In addition to the debt outstanding, as of December 31, 2019 we had an additional $150.0 million available through our revolving credit facility, with the ability to borrow another $100.0 million by increasing the commitments under the facility. Together with Adjusted Cash, we had $357.9 million available to fund our operations, capital expenditures, potential acquisitions, debt repayments and any dividends as of December 31, 2019. Dividends The Company’s expectation is to continue to pay dividends. The decision to pay a dividend, however, remains within the discretion of the Company's board of directors and may be affected by various factors, including our earnings, financial condition, capital requirements, level of indebtedness and other considerations our board of directors deems relevant. Future debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, our ability to pay dividends. Share Repurchase Program In 2011, the board of directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 millionequity securities and approved additional authorizations of $100 million in each of 2012, 2013, 2014, 2015 and 2016, $150 million in February 2018, $100 million in August 2018, and $250 million in October 2019, for a total authorization of $1.1 billion. The Company expects to fund repurchases primarily through the use of existing cash balances. The program permits the Company to purchase shares through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation. Under the program, for the year ended December 31, 2019, the Company repurchased 1,420,654 shares of common stock at an average cost per share of $110.42, totaling $156.9 million. Since inception of the program through December 31, 2019, the Company has repurchased 13,716,009 shares of common stock at an average cost per share of $58.38, totaling $800.8 million. As of December 31, 2019, the Company had $299.2 million of availability remaining under its existing share repurchase authorizations. OCC Capital Plan In December 2014, OCC announced a newly-formed capital plan, under which each of OCC's existing exchange stockholders agreed to contribute its pro-rata share, based on ownership percentage, of $150 million in equity capital, which would increase OCC's shareholders' equity, and to provide its pro rata share in replenishment capital, up to a maximum of $40 million per exchange stockholder, if certain capital thresholds were breached. OCC also adopted policies under the plan with respect to fees, customer refunds, and stockholder dividends, which envisioned an annual 74 Table of Contents dividend payment to the exchange stockholders. On March 3, 2015, in accordance with the plan, Cboe Options contributed $30 million to OCC. That contribution has been recorded under investments in the consolidated balance sheets as of December 31, 2019 and 2018. The SEC initially issued a notice of no objection to OCC’s advance notice filing regarding the capital plan and subsequently approved OCC’s proposed rule filing for the capital plan, but certain petitioners appealed the SEC approval order to the U.S. Court of Appeals for the D.C. Circuit. The court ultimately remanded the matter to the SEC, and on February 13, 2019, the SEC issued an order disapproving the proposed rule change implementing OCC’s capital plan. In an effort to achieve compliance with its target capital requirements in the absence of an approved capital plan, OCC (i) retained funds that otherwise would have been paid to stockholders as dividends and to clearing members as refunds with respect to 2018, and (ii) raised its clearing fees. In connection with the disapproval of the capital plan, OCC returned the capital that had been contributed by its shareholders under the disapproved plan (equal to $30.0 million for Cboe Options) to the respective shareholders in 2019, of which $22.0 million was returned to Cboe Options in the first quarter of 2019 and $8.0 million in the fourth quarter of 2019. With each return of capital described in this paragraph, the Company also incurred a tax expense. OCC agreed to reimburse the Company for part of that tax liability and paid the Company $1.1 million in the third quarter and $0.4 million in the fourth quarter of 2019. OCC did not pay its shareholders any dividend or other return on the retained portion of their capital contributions. As such, the Company reversed the $8.8 million OCC dividend declared in 2018, which was to be paid in 2019, in other income in the consolidated statement of income for the year ended December 31, 2019. The remaining contributed capital has been recorded under investments in the consolidated balance sheet as of December 31, 2019. On January 24, 2020, upon receipt of SEC approval, OCC established a new capital management policy intended to replace the disapproved capital plan. The new capital management policy provides that, if OCC’s equity capital falls below certain defined thresholds, OCC can access additional capital through an operational loss fee charged to clearing members. None of OCC’s shareholders (including Cboe Options) has any obligation to contribute capital to OCC under the new capital management policy, nor does any shareholder have the right to receive dividends from OCC under such policy. Lease and Obligations The Company currently leases additional office space, data centers and remote network operations center, with lease terms remaining from 4 months to 180 months as of December 31, 2019. In September 2019, we entered into two leases that will commence in 2020 for a new principal office space and trading floor space, both located in Chicago, Illinois. Total rent expense related to current and former lease obligations for the years ended December 31, 2019, 2018 and 2017 totaled $12.4 million, $10.1 million and $7.6 million, respectively. In addition to our lease obligations, we have contractual obligations related to certain operating leases, data and telecommunications agreements, and our long-term debt outstanding. Future minimum payments under these leases and agreements were as follows as of December 31, 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Payments Due by Period ​ ​ ​ ​ ​ ​ Less than ​ ​ ​ ​ ​ ​ ​ ​ More than ​      Total      ​ 1 year      ​ 1-3 years      ​ 4-5 years      ​ 5 years Contractual Obligations ​ (in millions) Operating leases ​ $ 164.3 ​ $ 11.3 ​ $ 30.5 ​ $ 25.9 ​ $ 96.6 Principal payments of debt ​   875.0 ​   — ​   225.0 ​   — ​   650.0 Interest payments on debt ​   187.0 ​   32.1 ​   80.9 ​   48.8 ​   25.2 Total ​ $ 1,226.3 ​ $ 43.4 ​ $ 336.4 ​ $ 74.7 ​ $ 771.8 ​ ​ 75 Table of Contents Off-Balance Sheet Arrangements As of December 31, 2019 and 2018, we did not have any off-balance sheet arrangements. Guarantees We use Wedbush and Morgan Stanley to clear our routed equities transactions in our U.S. Equities segment. Wedbush and Morgan Stanley guarantee the trade until one day after the trade date, after which time the NSCC provides a guarantee. In the case of failure to perform on the part of one of our clearing firms, Wedbush or Morgan Stanley, we provide the guarantee to the counterparty to the trade. OCC acts as a central counterparty on all transactions in listed equity options in our Options segment, and as such, guarantees clearance and settlement of all of our options transactions. We believe that any potential requirement for us to make payments under these guarantees is remote and accordingly, have not recorded any liability in the consolidated financial statements for these guarantees. Similarly, with respect to U.S. listed equity options and futures, we deliver matched trades of our customers to the OCC, which acts as a central counterparty on all transactions occurring on Cboe Options, C2, BZX, EDGX, and CFE and, as such, guarantees clearance and settlement of all of our matched options and futures trades. Critical Accounting Policies The preparation of consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of the amounts of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to areas that require a significant level of judgment or are otherwise subject to an inherent degree of uncertainty. The Company bases its estimates on historical experience, observance of trends in particular areas, information available from outside sources and various other assumptions that are believed to be reasonable under the circumstances. Information from these sources form the basis for making judgments about the carrying values of assets and liabilities that may not be readily apparent from other sources. We have identified the policies below as critical to our business operations and the understanding of our results of operations. The impact of, and any associated risks related to, these policies on our business operations is discussed throughout "Management's Discussion and Analysis of Financial Condition and Results of Operations." For a detailed discussion on the application of these and other accounting policies, see Note 2 (“Summary of Significant Accounting Policies”) to our consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K. Revenue Recognition For further discussion related to revenue recognition of fees, such as transaction fees and liquidity payments, access and capacity fees, market data fees, and regulation transaction and Section 31 fees, see Note 4 (“Revenue Recognition”). Goodwill and Other Intangible Assets Our acquisitions of Bats, Cboe Vest Financial Group Inc. (“Vest”), Silexx Financial Systems, LLC (“Silexx”), and LiveVol resulted in the recording of goodwill and other intangible assets. In accordance with ASC 350—Intangibles—Goodwill and Other, we test the carrying values of goodwill and indefinite-lived intangible assets for impairment at least annually, or more frequently when events or changes in circumstances signal indicators of impairment are present. We perform our annual impairment test of goodwill and other indefinite-lived intangible assets during the fourth quarter of our fiscal year, using the October 1 carrying values. Goodwill is tested for impairment at the reporting unit level in accordance with ASC 350-20. If the carrying value of the reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to the excess. If the fair value of indefinite-lived intangible assets is less than their carrying value, an impairment loss will be recognized in an amount equal to the difference. We performed our annual goodwill impairment test as of October 1, 2019 and determined that no impairment existed. 76 Table of Contents The estimated fair values of our reporting units are based on the market approach and the income approach (using discounted estimated future cash flows). The estimated fair values of indefinite-lived intangibles used the income approach. The discounted cash flow analysis requires significant judgment, including judgments about the discount rate, anticipated revenue growth rate, and operating expenses, that are inherent in these fair value estimates over the estimated remaining operating period. As such, actual results may differ from these estimates and lead to a revaluation of our goodwill and indefinite-lived intangible assets. If updated estimates indicate that the fair value of goodwill or any indefinite-lived intangibles is less than the carrying value of the asset, an impairment charge is expected to be recorded in the consolidated statements of income in the period of the change in estimate. Purchase Accounting Tangible and intangible assets acquired and liabilities assumed in an acquired business are recorded at their estimated fair values on the date of acquisition. The difference between the purchase price amount and the net fair value of assets acquired and liabilities assumed is recognized as goodwill on the balance sheet if the purchase price exceeds the estimated net fair value or as a bargain purchase gain on the income statement if the purchase price is less than the estimated net fair value. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment, often utilizes independent valuation experts and involves the use of significant estimates and assumptions with respect to the timing and amounts of future cash inflows and outflows, discount rates, market prices and asset lives, among other items. The judgments made in the determination of the estimated fair value assigned to the assets acquired and liabilities assumed, as well as the estimated useful life of each asset and the duration of each liability, could significantly impact the financial statements in periods after acquisition, such as through depreciation and amortization expense. When available, the estimated fair values of these assets and liabilities are determined based on observable inputs, such as quoted market prices, information from comparable transactions, offers made by other prospective acquirers, in such cases where we may have certain rights to acquire additional interests in existing investments, and the replacement cost of assets in the same condition or stage of usefulness (Level 1 and 2). Unobservable inputs, such as expected future cash flows orETFs internally developed estimates of value (Level 3), are used if observable inputs are not available. As noted in ASC 805—Business Combinations, the allocation of the purchase price may be modified up to twelve months after the acquisition date as more information is obtained about the fair value of assets acquired and liabilities assumed. See Note 5 (“Acquisitions”) for additional information. Stock-Based Compensation We have historically granted stock-based compensation to our employees in the form of restricted stock units. With the acquisition of Bats, we also assumed Bats’ grants of restricted stock and stock options to certain employees. We record the related stock-based compensation expense based on the grant date fair value calculated in accordance with the authoritative guidance issued by FASB. The Company used the Monte Carlo valuation model method to estimate the fair value of the total shareholder return performance share units, which incorporated the following assumptions: risk-free interest rate, three-year volatility, and three year correlation with S&P 500 Index. We recognize these stock-based compensation costs on a straight-line basis over the requisite service period of the award. We recognized stock-based compensation expense of approximately $21.8 million, $35.1 million, and $50.1 million for the years ended December 31, 2019, 2018 and 2017, respectively. This expense is included in the compensation and benefits expense and acquisition related costs in the consolidated statements of income. Income Taxes Deferred taxes are provided on a liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that all or some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based upon the technical merits of the position. The 77 Table of Contents tax benefit recognized in the consolidated financial statements from such a position is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Also, interest and penalties expense is recognized on the full amount of deferred benefits for uncertain tax positions. The Company’s policy is to include interest and penalties related to unrecognized tax benefits in the income tax provision within the consolidated statements of income. Recent Accounting Pronouncements See Note 3 (“Recent Accounting Pronouncements”) to the consolidated financial statements for further discussion of recently adopted and recently issued accounting pronouncements that are applicable to the Company. ​ ​ 78 Table of Contents Item 7A.      Quantitative and Qualitative Disclosures about Market Risk As a result of our operating activities, we are exposed to market risks such as foreign currency exchange rate risk, equity risk, credit risk, and interest rate risk. We have implemented policies and procedures to measure, manage and monitor and report risk exposures, which are reviewed regularly by management and our board of directors. Foreign Currency Exchange Rate Risk Our operations in Europe and Asia are subject to increased currency translation risk as revenues and expenses are denominated in foreign currencies, primarily the British pound, Singapore dollar, Hong Kong dollar, and the Euro. We also have de minimis exposure to other foreign currencies, including the Swiss Franc, Norwegian Kroner, Swedish Krona and Danish Kroner. For the year ended December 31, 2019, our exposure to foreign-denominated revenues and expenses is presented by primary foreign currency in the following table: ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ ​ December 31, 2019 ​ ​ ​ ​ ​ ​ British ​ ​      Euro (1)    ​ Pound (1) ​ ​   (in millions, except ​ ​   percentages) ​ Foreign denominated % of: ​ ​ ​ ​ ​ ​ Revenues ​ 0.3 % ​ 4.0 % Cost of revenues ​ 0.1 % ​ 1.4 % Operating expenses ​ 0.2 % ​ 5.5 % Impact of 10% adverse currency fluctuation on: ​ ​ ​ ​ ​ ​ Revenues $ 0.3 ​ $ 4.3 ​ Cost of revenues ​ 0.1 ​ ​ 0.6 ​ Operating expenses ​ 0.1 ​ ​ 1.0 ​ (1) An average foreign exchange rate to the U.S. dollar for the period was used. Equity Risk Our investment in European operations is exposed to volatility in currency exchange rates through translation of our net assets or equity to U.S. dollars. The assets and liabilities of our European business are denominated in British pounds or Euros. Fluctuations in currency exchange rates may create volatility in our reported results as we are required to translate foreign currency reported statements of financial condition and operational results into U.S. dollars for consolidated reporting. The translation of these non-U.S. dollar statements of financial condition into U.S. dollars for consolidated reporting results in a cumulative translation adjustment, which is recorded in accumulated other comprehensive loss (income) within stockholders' equity on our consolidated balance sheet. ​ Our primary exposure to this equity risk as of December 31, 2019 is presented by foreign currency in the following table: ​ ​ ​ ​ ​ ​ British ​      Pound (1) ​   (in millions) Net equity investment in Cboe Europe   $ 727.9 Impact on consolidated equity of a 10% adverse currency fluctuation   ​ 72.8 (1) Converted to U.S. dollars using the foreign exchange rate of British pounds per U.S. dollar as of December 31, 2019. 79 Table of Contents Credit Risk We are exposed to credit risk from third parties, including customers, counterparties and clearing agents. These parties may default on their obligations due to bankruptcy, lack of liquidity, operational failure or other reasons. We limit our exposure to credit risk by considering such risk when selecting the counterparties with which we make investments and execute agreements. We do not have counterparty credit risk with respect to trades matched on our exchanges inor routed to and executed on an external market center. (2) Average revenue per contract, for options and futures represents total net transaction fees recognized for the U.S.period divided by total contracts traded during the period. (3) Net capture per one hundred touched shares refers to transaction fees less liquidity payments and Europe. With respect to listed equities, we deliver matched tradesrouting and clearing costs divided by the product of our customers to the NSCC without taking on counterparty risk for those trades.

(15) Net capture per matched notional value refers to transaction fees less liquidity payments in Japanese Yen divided by the product of ADNV in Japanese Yen of shares matched on Cboe Japan and as such, guarantees clearancethe number of Japanese Equities trading days. (16) Net capture per one million dollars traded refers to net transaction fees less liquidity payments, if any, divided by the Spot and settlementSEF products of allone-thousandth of our matched options and futures trades. With respect to orders Cboe Trading routes to other markets for execution on behalf of our customers, Cboe Trading is exposed to some counterparty credit risk in the case of failure to perform on the part of our clearing firms, Morgan Stanley or Wedbush. Morgan Stanley and Wedbush guarantee trades until one day after the trade date, after which time NSCC provides a guarantee. Thus, Cboe Trading is potentially exposed to credit risk to the counterparty to a trade routed to another market center between the trade date and one day after the trade date in the event that Morgan Stanley or Wedbush fails. We believe that any potential requirement for us to make payments under these guarantees is remote and accordingly, have not recorded any liability in the consolidated financial statements for these guarantees. Historically, we have not incurred any liability due to a customer’s failure to satisfy its contractual obligations as counterparty to a system trade. Credit difficulties or insolvency, or the perceived possibility of credit difficulties or insolvency, of one or more larger or more visible market participants could also result in market-wide credit difficulties or other market disruptions. We do not have counterparty credit risk with respect to institutional spot FX trades occurring on our platform because Cboe FX is not a counterparty to any FX transactions. All transactions occurring on our platform occur bilaterally between two banks or prime brokers as counterparties to the trade. While Cboe FX does not have direct counterparty risk, Cboe FX may suffer a decrease in transaction volume if a bank or prime broker experiences an event that causes other prime brokers to decrease or revoke the credit available to the prime broker experiencing the event. Therefore, Cboe FX may have risk that is related to the credit of the banks and prime brokers that trade FXADNV traded on the Cboe FX platform. We also have credit risk related to transaction feesMarkets and the number of trading days, divided by two, which represents the buyer and seller that are billed in arrears to customers on a monthly basis. Our potential exposure to credit losses on these transactions is represented by the receivable balances in our balance sheet. Our customers are financial institutions whose ability to satisfy their contractual obligations may be impacted by volatile securities markets. On a regular basis, we review and evaluate changes in the status of our counterparties’ creditworthiness. Credit losses such as those described above could adversely affect our consolidated financial position and results of operations. Any such effects to date have been minimal. Interest Rate Risk We have exposure to market risk for changes in interest rates relating to our cash and cash equivalents, financial investments, and indebtedness. As of December 31, 2019 and 2018, our cash and cash equivalents and financial investments were $300.3 million and $310.8 million, respectively, of which $85.1 million and $72.9 million is held outside of the United States in various foreign subsidiaries in 2019 and 2018, respectively. The remaining cash and cash equivalents and financial investments are denominated in U.S. dollars. We do not use our investment portfolio for trading or other speculative purposes. Due to the nature of these investments, we have not been exposed to, nor do we 80 Table of Contents anticipate being exposed to, material risks due to changes in interest rates, assuming no change in the amount or composition of our cash and cash equivalents and financial investments. As of December 31, 2019, we had $875.0 million in outstanding debt, of which $650.0 million relates to our Senior Notes, which bear interest at fixed interest rates. Changes in interest rates will have no impactboth charged on the interest we pay on fixed-rate obligations. The remaining amount outstanding of $225.0 million relates to the Term Loan Agreement, which bears interest at fluctuating rates and, therefore, subjects us to interest rate risk. A hypothetical 100 basis point increase in interest rates relating to the amounts outstanding under the Term Loan Agreement as of December 31, 2019 would decrease annual pre-tax earnings by $2.3 million, assuming no change in the composition of our outstanding indebtedness. We are also exposed to changes in interest rates as a result of borrowings under our Revolving Credit Agreement, as this facility bears interest at fluctuating rates. As of December 31, 2019, there were no outstanding borrowings under our Revolving Credit Agreement. See Note 13 (“Debt”) to the consolidated financial statements for a discussion of debt agreements.transaction. ​ 70 Table of Contents Revenues Total revenues for the year ended December 31, 2021 increased $67.7 million, or 2%, compared to the prior period primarily due to a $275.1 million, or 11%, increase in transaction and clearing fees as a result of increased volumes traded on the Options exchanges and additional revenues attributable to acquisitions made in 2020 and 2021, partially offset by a decrease in regulatory fees as a result of a decline in the Section 31 fee rate.

Access and Capacity Fees Access and capacity fees increased for the year ended December 31, 2021 compared to the same period in 2020 primarily due to increases in subscribers which results in an increase in logical port revenue across the Options, Europe and Asia Pacific, and North American Equities segments, coupled with an increase in physical port revenue in the North American Equities and Options segments. Market Data Fees Market data fees increased for the year ended December 31, 2021 compared to the same period in 2020 primarily due to an increase in subscribers and additional revenue attributed to Chi-X Asia Pacific, which the Company acquired in the third quarter of 2021.

In the near term, we expect that our cash from operations and availability under the Revolving Credit Facility will meet our cash needs to fund our operations, capital expenditures, interest payments on debt, debt repayments, any dividends, and opportunities for common stock repurchases under the previously announced program. We may also utilize excess cash on hand to pay down amounts outstanding under the Term Loan Agreement. See Note 12 (“Debt”) to the consolidated financial statements for further information. To the extent that our cash sources are insufficient to fund our potential acquisitions, we may participate in future financing transactions to obtain additional capital. EuroCCP also has a €1.5 billion committed syndicated multicurrency revolving and swingline credit facility agreement with EuroCCP as borrower and the Company as guarantor of scheduled interest and fees on borrowings (but not the principal amount of any borrowings), (the “Facility”). The Facility is available to be drawn by EuroCCP towards (a) financing unsettled amounts in connection with the settlement of transactions in securities and other items processed through EuroCCP’s clearing system and (b) financing any other liability or liquidity requirement of EuroCCP incurred in the operation of its clearing system. Borrowings under the Facility are secured by cash, eligible bonds and eligible equity assets deposited by EuroCCP into secured accounts. As a result, should the Facility be drawn by EuroCCP it could potentially impact EuroCCP’s liquidity, and we can give no assurance that this Facility will be sufficient to meet all of such obligations or sufficiently mitigate EuroCCP’s liquidity risk to meet its payment obligations when due. Additionally, a default of the Facility may allow lenders, under certain circumstances, to accelerate any related drawn amounts and may result in the acceleration of the Company’s other outstanding debt to which a cross-acceleration or cross-default provision applies, which may limit the Company’s liquidity, business and financing activities. The Facility is expected to terminate on June 30, 2022 and we may not be able to enter into a replacement facility on commercially reasonable terms, or at all. Our long-term cash needs will depend on many factors, including an introduction of new products, enhancements of current products, the geographic mix of our business and any potential acquisitions. We believe our cash from operations and the availability under our Revolving Credit Facility will meet any long-term needs unless a significant acquisition or acquisitions are identified, in which case we expect that we would be able to borrow the necessary funds and/or issue additional shares of our common stock to complete such acquisition(s). In addition, we do not expect COVID-19 to have a material impact on our liquidity or capital resources, including cash from operations or uses of cash, or change our ability to access capital markets in the near term or the foreseeable future. Cash and cash equivalents include cash in banks and all non-restricted, highly liquid investments with original maturities of three months or less at the time of purchase. Cash and cash equivalents as of December 31, 2021 increased 81 Table of Contents $96.5 million from December 31, 2020 primarily due to results of operations, adjustment for depreciation expense, proceeds from available-for-sale financial investments, and proceeds from the term loan modification, partially offset by contributions to investments, cash dividends paid on common stock, and acquisitions, net of cash acquired. See “Cash Flow” below for further discussion. Our cash and cash equivalents held outside of the United States in various foreign subsidiaries totaled $185.9 million and $128.2 million as of December 31, 2021 and December 31, 2020, respectively. The remaining balance was held in the United States and totaled $156.0 million and $117.2 million as of December 31, 2021 and December 31, 2020, respectively. The majority of cash held outside the United States is available for repatriation, but under current law, could subject us to additional United States income taxes, less applicable foreign tax credits. Our financial investments include deferred compensation plan assets as well as investments with original or acquired maturities longer than three months but that mature in less than one year from the balance sheet date and are recorded at fair value. As of December 31, 2021, financial investments consisted of U.S. Treasury securities and deferred compensation plan assets. Our off-balance sheet arrangements include clearing operations related to EuroCCP. See Note 14 (“Clearing Operations”) for discussion of contingent assets and liabilities related to clearing operations in connection with the Company’s acquisition of EuroCCP. Cash Flow The following table summarizes our cash flow data for the years ended December 31, 2021, 2020 and 2019 (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Year Ended   ​ ​ December 31,   ​      2021      2020      2019   Net cash provided by operating activities ​ $ 596.8 ​ $ 1,458.8 ​ $ 632.8 ​ Net cash used in investing activities ​   (352.7) ​   (430.5) ​   (15.9) ​ Net cash used in financing activities ​   (200.3) ​   (201.7) ​   (662.9) ​ Effect of foreign currency exchange rate changes on cash, cash equivalents, and restricted cash and cash equivalents ​   (9.1) ​   1.6 ​   0.2 ​ Increase (decrease) in cash, cash equivalents, and restricted cash and cash equivalents ​ $ 34.7 ​ $ 828.2 ​ $ (45.8) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, ​ ​ ​ 2021      2020      2019 ​ Reconciliation of cash, cash equivalents, and restricted cash and cash equivalents: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 341.9 ​ $ 245.4 ​ $ 229.3 ​ Restricted cash and cash equivalents (margin deposits and clearing funds) ​ ​ 745.9 ​ ​ 812.1 ​ ​ — ​ Restricted cash and cash equivalents (included in other current assets) ​ ​ 4.4 ​ ​ — ​ ​ — ​ Total ​ $ 1,092.2 ​ $ 1,057.5 ​ $ 229.3 ​ ​ Net Cash Flows Provided by Operating Activities During the year ended December 31, 2021, net cash provided by operating activities was $67.8 million higher than net income. The variance is primarily attributable to the adjustment for depreciation and amortization expense of $167.4 million, the change in accounts payable and accrued liabilities of $45.0 million, and the change in unrecognized tax benefits of $33.2 million, partially offset by the change in Section 31 fees payable of $112.1 million and the change in restricted cash and cash equivalents, driven by a $66.2 million decrease in margin deposits and clearing funds related to EuroCCP for the year ended December 31, 2021. Net cash flows provided by operating activities were $596.8 million and $1,458.8 million for the years ended December 31, 2021 and 2020, respectively. The change in net cash flows provided by operating activities was primarily due to the change in restricted cash and cash equivalents, driven by margin deposits and clearing funds related to EuroCCP, as well as the change in Section 31 fees payable, partially offset by the change in accounts receivable, as well as the change in the bargain purchase gain and provision for deferred income taxes for the year ended December 31, 2021 compared to the year ended December 31, 2020. 82 Table of Contents Net cash provided by operating activities was $990.6 million higher than net income for the fiscal year ended December 31, 2020. The variance is primarily attributed to the addition of $812.1 million of restricted cash and cash equivalents, driven by margin deposits and clearing funds related to EuroCCP, the adjustment for depreciation and amortization expense of $158.5 million, the change in accounts payable and accrued liabilities of $59.4 million, and the change in Section 31 fees payable of $53.9 million, partially offset by the change in accounts receivable of $90.0 million. Net cash provided by operating activities was $1,458.8 million and $632.8 million for the years ended December 31, 2020 and 2019, respectively. The increase in net cash flows provided by operating activities was primarily due to the addition of margin deposits and clearing funds resulting from the EuroCCP acquisition and the increase in net income. Net Cash Flows Used in Investing Activities During the year ended December 31, 2021, net cash used in investing activities primarily consisted of contributions to investments of $209.8 million, acquisitions, net of cash acquired of $151.5 million, and purchases of available-for-sale financial investments of $101.2 million, partially offset by proceeds from available-for-sale financial investments of $160.2 million. Net cash flows used in investing activities were $352.7 million and $430.5 million for the years ended December 31, 2021 and 2020, respectively. The variance is primarily due to the change in acquisitions, net of cash acquired, and the change in purchases of available-for-sale financial investments, partially offset by contributions to investments and the change in proceeds from available-for-sale financial investments for the year ended December 31, 2021 compared to the year ended December 31, 2020. Net cash flows used in investing activities totaled $430.5 million and $15.9 million for the years ended December 31, 2020 and 2019, respectively. The variance is primarily due to acquisitions, net of cash acquired in 2020 and the return of capital from investments in 2019. Capital expenditures are expected to be in the range of $47.0 million to $52.0 million, reflecting expenditures associated with the Company’s trading floor relocation, which is anticipated to occur in the second quarter of 2022, ongoing capacity and technology-related investments, as well as anticipated project delays due to supply chain interruptions. Net Cash Flows Used in Financing Activities During the year ended December 31, 2021, net cash used in financing activities primarily consisted of cash dividends paid on common stock of $193.3 million and share repurchases of $81.3 million, partially offset by proceeds from long-term debt of $110.0 million. Net cash flows used in financing activities were $200.3 million and $201.7 million for the years ended December 31, 2021 and 2020, respectively. The variance is primarily due to the change in share repurchases, as well as the change in principal payments of long-term debt, partially offset by the change in proceeds from long-term debt. For the year ended December 31, 2020, the Company received proceeds from long-term debt of $493.7 million, of which $70.0 million was used to pay down the revolving credit facility draw taken in the third quarter of 2020, repurchased $349.1 million of common stock, paid dividends totaling $170.6 million, and paid down $155.0 million of long-term debt. Net cash flows used in financing activities totaled $662.9 million for the year ended December 31, 2019. The Company paid down $350.0 million of long-term debt, repurchased $156.9 million of common stock, and paid dividends of $150.0 million. 83 Table of Contents Financial Assets The following summarizes our financial assets excluding margin deposits and clearing funds as of December 31, 2021, 2020 and 2019 (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, ​      2021      2020      2019 Cash and cash equivalents ​ $ 341.9 ​ $ 245.4 ​ $ 229.3 Financial investments ​   37.1 ​   92.4 ​   71.0 Less deferred compensation plan assets ​ ​ (28.0) ​ ​ (24.5) ​ ​ (23.4) Less cash collected for Section 31 fees ​ ​ (25.9) ​ ​ (103.0) ​ ​ (69.0) Adjusted cash (1) ​ $ 325.1 ​ $ 210.3 ​ $ 207.9 (1) Adjusted cash is a non-GAAP measure and represents cash and cash equivalents plus financial investments, minus deferred compensation plan assets and cash collected for Section 31 fees. We have presented adjusted cash because we consider it an important supplemental measure of our liquidity and believe that it is frequently used by analysts, investors and other interested parties in the evaluation of companies. Debt ​ The following summarizes our debt obligations as of December 31, 2021, 2020 and 2019 (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, ​      2021      2020      2019 Term Loan Agreement ​ $ 160.0 ​ $ 70.0 ​ $ 225.0 3.650% Senior Notes ​   650.0 ​   650.0 ​   650.0 1.625% Senior Notes ​ ​ 500.0 ​ ​ 500.0 ​ ​ — Revolving Credit Agreement ​ ​ — ​ ​ — ​ ​ — EuroCCP Credit Facility ​ ​ — ​ ​ — ​ ​ — Less unamortized discount and debt issuance costs ​ ​ (10.7) ​ ​ (16.1) ​ ​ (7.4) Total debt ​ $ 1,299.3 ​ $ 1,203.9 ​ $ 867.6 ​ At December 31, 2021, we were in compliance with the covenants of our debt agreements. In addition to the debt outstanding, as of December 31, 2021, we had an additional $250.0 million available through our revolving credit facility, with the ability to borrow another $100.0 million by increasing the commitments under the facility. Together with adjusted cash, we had $675.1 million available to fund our operations, capital expenditures, potential acquisitions, debt repayments and any dividends as of December 31, 2021. Dividends The Company’s expectation is to continue to pay dividends. The decision to pay a dividend, however, remains within the discretion of the Company's Board of Directors and may be affected by various factors, including our earnings, financial condition, capital requirements, level of indebtedness and other considerations our Board of Directors deems relevant. Future debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, our ability to pay dividends. Share Repurchase Program In 2011, the Board of Directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and approved additional authorizations of $100 million in each of 2012, 2013, 2014, 2015 and 2016, $250 million in each of 2018, 2019 and 2020, and $200 million in February 2021, for a total authorization of $1.6 billion. The program permits the Company to purchase shares through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation. ​ 84 Table of Contents Under the program, for the year ended December 31, 2021, the Company repurchased 822,005 shares of common stock at an average cost per share of $98.82, totaling $81.3 million. Since inception of the program through December 31, 2021, the Company has repurchased 18,072,129 shares of common stock at an average cost per share of $68.12, totaling $1.2 billion. As of December 31, 2021, the Company had $318.9 million of availability remaining under its existing share repurchase authorizations. Lease and Obligations The Company currently leases additional office space, data centers and remote network operations center, with lease terms remaining from 7 months to 186 months as of December 31, 2021. In September 2019, we entered into two leases that commenced in 2020 for a new principal office space and trading floor space, both located in Chicago, Illinois. Additionally, in October 2021, the Company signed a new lease that commenced in February 2022 for a new principal office space in Amsterdam. See Note 24 (“Leases”) to the consolidated financial statements for additional information. Total rent expense related to current and former lease obligations for the years ended December 31, 2021, 2020 and 2019 totaled $25.6 million, $20.2 million and $12.4 million, respectively. In addition to our lease obligations, we have contractual obligations related to certain operating leases, data and telecommunications agreements, and our long-term debt outstanding. Purchase obligations include our estimate of the minimum outstanding obligations under agreements to purchase goods or services that we believe are enforceable and legally binding and that specify all significant terms, including fixed or minimum quantities to be purchased; fixed or minimum and maximum amounts to be paid; and the approximate timing of the transaction. Purchase obligations include certain licensing agreements with various licensors which contain annual minimum fee requirements as well as payments calculated using agreed upon contract rates and reported cleared volumes. Purchase obligations exclude agreements that are cancellable at any time without penalty. We have excluded from the contractual obligations listed below $745.9 million in cash margin deposits and clearing funds. Clearing participants of EuroCCP are required to make deposits to a clearing fund. The cash deposits made by clearing participants are recorded in the consolidated balance sheet as current assets with equal and offsetting current liabilities. See Note 14 (“Clearing Operations”) to the consolidated financial statements for additional information on EuroCCP and the margin deposits and clearing funds. Future minimum payments under these leases and agreements were as follows as of December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Payments Due by Period ​ ​ ​ ​ ​ ​ Less than ​ ​ More than ​      Total      ​ 1 year      ​ 1 year Contractual Obligations ​ ​ Operating leases ​ $ 149.1 ​ $ 19.3 ​ $ 129.8 Purchase obligations ​ ​ 871.5 ​ ​ 69.0 ​ ​ 802.5 Principal payments of debt ​   1,310.0 ​   — ​   1,310.0 Interest payments on debt ​   194.7 ​   33.1 ​   161.6 Total ​ $ 2,525.3 ​ $ 121.4 ​ $ 2,403.9 ​ Commercial Commitments and Contractual Obligations As of December 31, 2021, our commercial commitments and contractual obligations included operating leases, data and telecommunications agreements, equipment leases, our long-term debt outstanding, contingent considerations and other obligations. See Note 23 (“Commitments, Contingencies, and Guarantees”) to the consolidated financial statements for a discussion of commitments and contingencies, Note 12 (“Debt”) for a discussion of the outstanding debt, Note 14 (“Clearing Operations”) for information on EuroCCP’s clearinghouse exposure guarantee, and Note 24 (“Leases”) for discussion on operating leases and equipment leases.

Wedbush and Morgan Stanley guarantee the trade until one day after the trade date, after which time the NSCC provides a guarantee. The BIDS Trading ATS platform delivers matched trades to BOA, which delivers the matched trades to the NSCC. BOA guarantees the trade until one day after the trade date, after which time the NSCC provides a guarantee.

In the case of failure to perform on the part of BOA on transactions for the BIDS Trading ATS platform, BIDS has obligations to the counterparties to satisfy the trades. OCC acts as a central counterparty on all transactions in listed equity options in our Options segment, and as such, guarantees clearance and settlement of all of our options transactions. We believe that any potential requirement for us to make payments under these guarantees is remote and accordingly, have not recorded any liability in the consolidated financial statements for these guarantees.

CRITICAL ACCOUNTING ESTIMATES The preparation of consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of the amounts of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to areas that require a significant level of judgment or are otherwise subject to an inherent degree of uncertainty. The Company bases its estimates on historical experience, observance of trends in particular areas, information available from outside sources and various other assumptions that are believed to be reasonable under the circumstances. Information from these sources form the basis for making judgments about the carrying values of assets and liabilities that may not be readily apparent from other sources. We have identified the estimates below as critical to our business operations and the understanding of our results of operations. The impact of, and any associated risks related to, these estimates on our business operations is discussed throughout "Management's Discussion and Analysis of Financial Condition and Results of Operations." For a detailed discussion on these estimates and other accounting policies, see Note 2 (“Summary of Significant Accounting Policies”) to the consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K.

(“Vest”), Silexx Financial Systems, LLC (“Silexx”), LiveVol, Hanweck, FT Options, Trade Alert, MATCHNow, BIDS Holdings and Chi-X APAC resulted in the recording of goodwill and other intangible assets, while our acquisition of EuroCCP, resulted in a bargain purchase gain and other intangible assets. In accordance with ASC 350—Intangibles—Goodwill and Other, we test the carrying values of goodwill and indefinite-lived intangible assets for impairment at least annually, or more frequently when events or changes in circumstances signal indicators of impairment are present. Judgments and Uncertainties The estimated fair values of our reporting units are based on the market approach and the income approach (using discounted estimated future cash flows). The estimated fair values of indefinite-lived intangibles used the income approach. The discounted estimated future cash flow analysis requires judgments about the discount rate, forecasted revenue growth rate, and operating expenses, that are inherent in these fair value estimates over the estimated remaining operating period. Additionally, the analysis contains uncertainty surrounding future events. As such, actual results may differ from these estimates and lead to a revaluation of our goodwill and indefinite-lived intangible assets. ​ 86 Table of Contents Effect if Actual Results Differ from Assumptions ​ If updated estimates indicate that the fair value of goodwill or any indefinite-lived intangibles is less than the carrying value of the asset, an impairment charge is expected to be recorded in the consolidated statements of income in the period of the change in estimate, which could result in a material change to the consolidated financial statements. However, due to the results of our impairment analyses in 2021, in which all reporting units estimated fair value exceeded their carrying value, we do not consider our goodwill and indefinite-lived intangibles to have a significant risk of impairment. ​ Income Taxes ​ Description The Company’s consolidated global income tax provision, deferred tax assets and liabilities, valuation allowances, and liabilities for unrecognized tax benefits are determined through the interpretation of tax laws and assumptions of future events to calculate an expectation of future tax consequences. Judgments and Uncertainties On an ongoing basis, the Company evaluates its tax estimates and judgments. This evaluation is based on factors including historical experience, such as the conclusions of examinations by tax authorities, changes in tax laws or rates, new examination activity, and results of any related legal processes. We use judgment in the evaluation of uncertain tax positions and the estimation of unrecognized tax benefits when determining the largest amount greater than 50% likely to be realized upon ultimate settlement with the taxing authority, assessing the likelihood of the benefit being realized upon settlement, and the calculating expected ultimate settlement amount. Effect if Actual Results Differ from Assumptions Significant changes in these estimates or judgments may result in an increase or decrease to our tax provision in a future period. Additionally, it is possible that the ultimate settlement may differ from the liabilities for unrecognized tax benefits currently reported if tax authorities ultimately reach a conclusion that differs from the Company’s expectation. We believe assumptions made regarding income taxes to be reasonable and do not believe any change in the judgments made by management would result in a material change to the consolidated financial statements.

Item 7A.      Quantitative and Qualitative Disclosures about Market Risk As a result of our operating activities, we are exposed to market risks such as foreign currency exchange rate risk, equity risk, credit risk, interest rate risk, and liquidity risk. We have implemented policies and procedures to measure, manage and monitor and report risk exposures, which are reviewed regularly by management and our Board of Directors. Foreign Currency Exchange Rate Risk Our operations in Europe, Canada and Asia are subject to increased currency translation risk as revenues and expenses are denominated in foreign currencies, primarily the British pound, Canadian dollar, Singapore dollar, Hong Kong dollar, Euro, Australian dollar, and Japanese Yen. We also have de minimis exposure to other foreign currencies, including the Swiss Franc, Norwegian Kroner, Swedish Krona, Danish Kroner, and Philippine Peso. 87 Table of Contents For the year ended December 31, 2021, our exposure to foreign-denominated revenues and expenses is presented by primary foreign currency in the following table (in millions, except percentages): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended   ​ December 31, 2021 ​ ​ British ​ ​ ​ ​ ​ Australian ​ ​ Pounds (1) ​ ​ Euros (1) ​ ​ Dollars (1) ​ Foreign denominated % of: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues ​ 1.9 %   ​ ​ 2.8 %   ​ ​ 0.3 %   Cost of revenues ​ 0.2 % ​ ​ 2.1 % ​ ​ 0.0 % Operating expenses ​ 3.5 % ​ ​ 5.7 % ​ ​ 1.4 % Impact of 10% adverse currency fluctuation on: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenues $ 6.6 ​ ​ $ 9.5 ​ ​ $ 1.1 ​ Cost of revenues ​ 0.4 ​ ​ ​ 4.0 ​ ​ ​ 0.0 ​ Operating expenses ​ 2.3 ​ ​ ​ 3.8 ​ ​ ​ 0.9 ​ (1) An average foreign exchange rate to the U.S. dollar for the period was used. See Item 7 (“Management’s Discussion and Analysis of Financial Condition and Results of Operations”) for the table summarizing the changes in certain operational and financial metrics for more information. Equity Risk Our investment in European, Canadian, and Asia Pacific operations is exposed to volatility in currency exchange rates through translation of our net assets or equity to U.S. dollars. The assets and liabilities of our European businesses are denominated in British pounds or Euros. The assets and liabilities of our Canadian businesses are denominated in Canadian dollars. The assets and liabilities of our Asia Pacific businesses are denominated in Hong Kong dollars, Australian dollars, Japanese Yen, or Philippine Pesos. Fluctuations in currency exchange rates may create volatility in our reported results as we are required to translate foreign currency reported statements of financial condition and operational results into U.S. dollars for consolidated reporting. The translation of these non-U.S. dollar statements of financial condition into U.S. dollars for consolidated reporting results in a cumulative translation adjustment, which is recorded in accumulated other comprehensive income, net within stockholders' equity on our consolidated balance sheet. Our primary exposure to this equity risk as of December 31, 2021 is presented by foreign currency in the following table (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ British ​ ​ ​ Canadian ​      Pounds (1) ​ Euros (1) ​ Dollars (1) Net equity investment in Cboe Europe, EuroCCP, and MATCHNow   $ 657.0 ​ $ 101.5 ​ $ 151.9 Impact on consolidated equity of a 10% adverse currency fluctuation   ​ 65.7 ​ ​ 10.1 ​ ​ 15.2 (1) Converted to U.S. dollars using the foreign exchange rate of British pounds per U.S. dollar, Euros per U.S. dollar, and Canadian dollars per U.S. dollar, respectively, as of December 31, 2021. Credit Risk We are exposed to credit risk from third parties, including customers, counterparties and clearing agents. These parties may default on their obligations due to bankruptcy, lack of liquidity, operational failure or other reasons. We limit our exposure to credit risk by considering such risk when selecting the counterparties with which we make investments and execute agreements. We do not have counterparty credit risk with respect to trades matched on our exchanges in the U.S., Canada, and Europe. With respect to listed equities, we deliver matched trades of our customers to the NSCC without taking on counterparty risk for those trades. NSCC acts as a central counterparty on all equity transactions occurring on BZX, BYX, EDGX and EDGA and, as such, guarantees clearance and settlement of all of our matched equity trades. Similarly, with respect to U.S. listed equity options and futures, we deliver matched trades of our customers to the OCC, which acts as a central counterparty on all transactions occurring on Cboe Options, C2, BZX, EDGX and CFE and, as such, guarantees clearance and settlement of all of our matched options and futures trades. With respect to Canadian equities, we deliver matched trades of our customers to The Canadian Depository for Securities, which acts as a central counterparty on all transactions occurring on MATCHNow and, as such, guarantees clearance and settlement of all of our matched Canadian equities trades. The BIDS Trading ATS platform delivers matched trades to BOA, which delivers the matched trades to the NSCC. BOA guarantees the trade until one day after the trade date, after which time the NSCC provides a guarantee. 88 Table of Contents Thus, BIDS Trading is potentially exposed to credit risk to the counterparty between the trade date and one day after the trade date in the event BOA fails. With respect to Australian equities and derivatives, we deliver matched trades of our customers to ASX Clear Pty Ltd and ASX Settlement Pty Ltd. ASX Clear Pty Ltd acts as a central counterparty on all transactions occurring on Cboe Australia and, as such, guarantees clearance and settlement on all of our matched trades in Australia. With respect to Japanese equities, we deliver matched trades of our customers to the Japanese Securities Clearing Corporation, which acts as a central counterparty on all transactions occurring on Cboe Japan and, as such, guarantees clearance and settlement on all of our matched trades in Japan. With respect to orders Cboe Trading routes to other markets for execution on behalf of our customers, Cboe Trading is exposed to some counterparty credit risk in the case of failure to perform on the part of our clearing firms, Morgan Stanley or Wedbush. Morgan Stanley and Wedbush guarantee trades until one day after the trade date, after which time NSCC provides a guarantee. The BIDS Trading ATS platform delivers matched trades to BOA, which delivers the matched trades to the NSCC. Thus, Cboe Trading is potentially exposed to credit risk to the counterparty to a trade routed to another market center between the trade date and one day after the trade date in the event that Morgan Stanley or Wedbush fails. The BIDS Trading ATS platform is potentially exposed to counterparty credit risk on equities trades between the trade date and one day after the trade date in the event that BOA fails. We believe that any potential requirement for us to make payments under these guarantees is remote and accordingly, have not recorded any liability in the consolidated financial statements for these guarantees. Historically, we have not incurred any liability due to a customer’s failure to satisfy its contractual obligations as counterparty to a system trade. Credit difficulties or insolvency, or the perceived possibility of credit difficulties or insolvency, of one or more larger or more visible market participants could also result in market-wide credit difficulties or other market disruptions. We do not have counterparty credit risk with respect to institutional spot FX trades occurring on our platform because Cboe FX is not a counterparty to any FX transactions. All transactions occurring on our platform occur bilaterally between two banks or prime brokers as counterparties to the trade. While Cboe FX does not have direct counterparty risk, Cboe FX may suffer a decrease in transaction volume if a bank or prime broker experiences an event that causes other prime brokers to decrease or revoke the credit available to the prime broker experiencing the event. Therefore, Cboe FX may have risk that is related to the credit of the banks and prime brokers that trade FX on the Cboe FX platform. We also have credit risk related to transaction fees that are billed in arrears to customers on a monthly basis. Our potential exposure to credit losses on these transactions is represented by the receivable balances in our balance sheet. Our customers are financial institutions whose ability to satisfy their contractual obligations may be impacted by volatile securities markets. As a result of the acquisition of EuroCCP on July 1, 2020, the Company is exposed to further credit risk through our clearing operations. EuroCCP holds material amounts of clearing participant collateral, both cash and non-cash deposits, which are held or invested primarily to provide security of capital while minimizing credit risk as well as liquidity and market risks. The following is a summary of the risks associated with these deposits and how these risks are mitigated: •Credit Risk -The credit risk is predominantly in the event a clearing participant fails to meet a financial or contractual obligation. EuroCCP attempts to mitigate this risk through minimum participant requirements for clearing participants and monitoring their financial health. To cover potential loss to EuroCCP in the event of a clearing participant default, collateral is required from clearing participants. Besides potential defaults of clearing participants, the main credit risk faced by the clearinghouse is exposure to clearing participants when a trade fails to settle. To help mitigate this risk, a fail fee is charged to discourage late settlements. This fee covers EuroCCP’s costs but also acts as a deterrent as required by Regulation (EU) No 236/2012 on short selling, together with certain aspects of credit default swaps. •Liquidity Risk -Liquidity risk is the risk EuroCCP may not be able to meet its payment obligations in the right currency, in the right place and at the right time. To help mitigate this risk, EuroCCP monitors its liquidity requirements closely and maintains funds and assets in a manner which attempt to minimize the risk of loss or delay in the access by the clearinghouse to such funds and assets. For example, holding funds with a central bank where possible or making only short-term investments serves to help reduce liquidity risks. Liquidity is mainly required for securities settlement. The payment and settlement obligations generally stem from the function of EuroCCP as a cash equity clearinghouse: shares are bought and sold by clearing participants on a trading platform or OTC, and netted to settle two days later. During the settlement the actual payment for and delivery of the shares take place, this process requires intraday liquidity. If 89 Table of Contents counterparties, which receive shares against payment, are unable to settle, an overnight liquidity need arises. The overnight liquidity is typically very short term, and is usually limited to a few days. •Market Risk - EuroCCP is also exposed to market risk in the event that a clearing participant defaults and the market prices of the securities in its open positions have moved adversely so the clearinghouse can only close out the participant’s obligations at a loss. To help mitigate market risk, EuroCCP collects collateral from clearing participants to cover for the probable loss during normal market conditions, together with contributions to the clearing fund to cover losses if a default occurred during extreme but plausible market conditions. Adverse movements in exchange rates affecting the value of obligations and collateral are factored into the calculation of the amount of collateral to be collected. On a regular basis, we review and evaluate changes in the status of our counterparties’ creditworthiness. Credit losses such as those described above could adversely affect our consolidated financial position and results of operations. Any such effects to date have been minimal. Interest Rate Risk We have exposure to market risk for changes in interest rates relating to our cash and cash equivalents, financial investments, and indebtedness. As of December 31, 2021 and 2020, our cash and cash equivalents and financial investments were $379.0 million and $337.8 million, respectively, of which $185.9 million and $128.0 million is held outside of the United States in various foreign subsidiaries in 2021 and 2020, respectively. The remaining cash and cash equivalents and financial investments are denominated in U.S. dollars. We do not use our investment portfolio for trading or other speculative purposes. Due to the nature of these investments, we have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates, assuming no change in the amount or composition of our cash and cash equivalents and financial investments. As of December 31, 2021, we had $1,299.3 million in outstanding debt, of which $1,139.9 million relates to our Senior Notes, which bear interest at fixed interest rates. Changes in interest rates will have no impact on the interest we pay on fixed-rate obligations. The remaining amounts outstanding of $159.5 million relates to the Term Loan Agreement, which bears interest at fluctuating rates and, therefore, subjects us to interest rate risk. A hypothetical 100 basis point increase in interest rates relating to the amounts outstanding under the Term Loan Agreement as of December 31, 2021 would decrease annual pre-tax earnings by $1.6 million, assuming no change in the composition of our outstanding indebtedness. We are also exposed to changes in interest rates as a result of borrowings under our Revolving Credit Agreement and the EuroCCP Credit Facility, as these facilities bear interest at fluctuating rates. As of December 31, 2021, there were no outstanding borrowings under our Revolving Credit agreement and no outstanding borrowings under the EuroCCP Credit Facility. See Note 12 (“Debt”) to the consolidated financial statements for a discussion of debt agreements. Liquidity Risk We are exposed to liquidity risk under certain circumstances in relation to the cross-acceleration and cross-default provisions within the Term Loan Agreement and the Revolving Credit Agreement as a result of the Company, as guarantor, entering into the EuroCCP Credit Facility. A default of the Facility may allow lenders to accelerate any related drawn amounts and may result in the acceleration of the Company’s other outstanding debt to which a cross-acceleration or cross-default provision applies, which may limit the Company’s liquidity, business and financing activities. See Note 12 (“Debt”) to the consolidated financial statements for a discussion of debt agreements. ​ 90 Table of Contents Item 8.      Financial Statements and Supplementary Data INDEX TO CONSOLIDATED FINANCIAL STATEMENTS ​ ​ Cboe Global Markets, Inc. and Subsidiaries ​ Reports of Independent Registered Public Accounting FirmFirms (PCAOB ID 185 and 34) 8392 Consolidated Financial Statements: ​ Consolidated Balance Sheets 8697 Consolidated Statements of Income 8798 Consolidated Statements of Comprehensive Income 8899 Consolidated Statements of Changes in Stockholders’ Equity 89100 Consolidated Statements of Cash Flows 90101 Notes to Consolidated Financial Statements 91102 ​ ​ ​ ​ 8291 Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMReport of Independent Registered Public Accounting Firm To the Stockholders and the Board of Directors of Cboe Global Markets, Inc.: ​ Opinion on the Consolidated Financial Statements ​ We have audited the accompanying consolidated balance sheets of Cboe Global Markets, Inc. and subsidiaries (the "Company")Company) as of December 31, 20192021 and 2018,2020, the related consolidated statements ofincome, comprehensive income, stockholders'changes in stockholders’ equity, and cash flows for each of the three years in the periodthen ended, December 31, 2019, and the related notes (collectively, referred to as the "financial statements")consolidated financial statements).

The communication of a critical audit mattersmatter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Evaluation of unrecognized tax benefits Goodwill — US Equities, European Equities, and Global FX Reporting Units—and Indefinite-lived Intangible Assets — Refer toAs discussed in Notes 2 and 1121 to the consolidated financial statements, Critical Audit Matter Description The Company’s evaluation of goodwill for impairment involves the comparisonCompany recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based upon the technical merits of the fair valueposition. The tax benefit recognized in the consolidated financial statements from such a position is measured based upon the largest benefit that has greater than 50% likelihood of each reporting unit to its carrying value. The Company’s evaluation of indefinite-lived intangibles (i.e., trading registrations and licenses) for impairment involves the comparison of the aggregate fair value to carrying value. The Company determines the fair value of its reporting units using both income and market approaches, and the fair value of indefinite-lived intangiblesbeing realized upon ultimate settlement. 8392 Table of Contents using an income approach. The determinationWe identified the evaluation of fair value using an income approach requires management to make significant estimates and assumptions related to future revenues. The goodwill balance was $2.68 billionunrecognized tax benefits in certain jurisdictions as of December 31, 2019, of which $1,740.4 million, $435.1 million, and $267.2 million was allocated to the US Equities, European Equities, and Global FX reporting units, respectively. The indefinite-lived intangibles balance was $850.4 million as of December 31, 2019. The fair values of the US Equities, European Equities, and Global FX reporting units, and the indefinite-lived intangibles exceeded their carrying values as of the measurement date and, therefore, no impairment was recognized. Given the significant judgments made by management to estimate future revenues, auditing the future revenue assumptions for the US Equities, European Equities, and Global FX reporting units and indefinite-lived intangibles required a highcritical audit matter. A higher degree of auditor judgment and an increased extentthe involvement of effort,professionals with specialized skills and knowledge was required to evaluate the Company’s estimate of tax benefits to be realized upon ultimate settlement of its tax positions. The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s unrecognized tax benefits process, including controls over the estimate of tax benefits to be realized upon ultimate settlement of tax positions. We evaluated the Company’s ability to estimate its unrecognized tax benefits by comparing historical unrecognized tax benefits to actual results upon the conclusion of examinations by applicable taxing authorities. In addition, we involved tax professionals with specialized skills and knowledge who assisted in: —analyzing the Company’s tax positions, including the need to involve our fair value specialists, given the difference between the carrying valuemeasurement of unrecognized tax benefits —evaluating changes in applicable laws and the fair value for each. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the future revenue assumptions for the US Equities, European Equities, and Global FX reporting units and indefinite-lived intangibles included the following, among others: ● We tested the effectiveness of controls over goodwill and indefinite-lived intangibles, including those over the future revenue assumptions.regulations ● We evaluated management’s ability to accurately forecast future revenues by comparing actual revenues to management’s historical forecasts. ● We evaluated the reasonableness of management’s future revenue assumptions by: o Comparing management’s forecasts with: —inspecting settlements with applicable taxing authorities. ◾ Historical revenues. ◾ Internal communications to management and the Board of Directors. ◾ Forecasted information included in Company press releases, as well as analyst and industry reports of the Company and companies in its peer group. o Evaluated the impact of changes in the regulatory environment for exchanges and of industry developments on management’s forecasts. o Evaluated the impact of changes in management’s forecasts subsequent to October 1, 2019, the annual assessment date. o Performed sensitivity analyses to identify potential bias in the determination of the future revenue assumptions. ● With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodologies and (2) long-term revenue growth rates by: o Testing the underlying source information and the mathematical accuracy of the calculations o Developing a range of independent estimates and comparing those to the long-term revenue growth rates selected by management. ​ /s/ DELOITTE & TOUCHEKPMG LLP Chicago, Illinois February 21, 2020 ​ We have served as the Company’s auditor since 1973.2020.

Definition and Limitations of Internal Control overOver Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely 95 Table of Contents detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ DELOITTE & TOUCHEKPMG LLP Chicago, Illinois February 21, 202018, 2022 ​ ​ ​ ​ 8596 Table of Contents Cboe Global Markets, Inc. and Subsidiaries

(b) Basis of Presentation The accompanying financial statements are presented on a consolidated basis to include the accounts and transactions of Cboe Global Markets, Inc. and its majority owned subsidiaries and all significant intercompany accounts and transactions have been eliminated. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, valuation of redeemable noncontrolling interest and reported amounts of revenues and expenses. On an ongoing basis, management evaluates its estimates based upon historical experience, observance of trends, information available from outside sources and various other assumptions that management believes to be reasonable under the circumstances. Actual results may differ from these estimates under different conditions or assumptions. For those consolidated subsidiaries in which the Company’s ownership is less than 100% and for which the Company has control over the assets and liabilities and the management of the entity, the outside stockholders’ interests areinterest is shown as non-controllingnoncontrolling interest. Segment information The Company has 5 business segments: Options, U.S.North American Equities, Europe and Asia Pacific, Futures, European Equities, and Global FX, which is reflective of how the Company’s chief operating decision-maker reviews and operates the business. See Note 1716 (“Segment Reporting”) for more information. 91 Table of Contents (c) Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as well as disclosure of the amounts of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of 102 Table of Contents revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the valuation of goodwill, indefinite-lived intangible assets, and unrecognized tax benefits. (d) Cash and Cash Equivalents The Company’s cash and cash equivalents are exposed to concentrations of credit risk. The Company maintains cash at various regulated financial institutions and brokerage firms which, at times, may be in excess of the federal depository insurance limit. The Company’s management regularly monitors these institutions and believes that the potential for future loss is remote. The Company considers all liquid investments with original or acquired maturities of three months or less to be cash equivalents. (e) Financial Investments Financial investments are classified as trading or available-for-sale. Trading financial investments represent financial investments held by the Company’s broker-dealer subsidiaryCboe Trading that retain the industry-specific accounting classification required for broker-dealers and marketable securities held in a rabbi trust for the Company’s non-qualified retirement and benefit plans. The investments held by the broker-dealer subsidiary are recorded at fair value with changes in unrealized gains and losses reflected within interest expense, net in the consolidated statements of income. The investments held in a rabbi trust are recorded at fair value with changes in unrealized gains or losses recorded within other income (expense) and the equal and offsetting charges in the related liability are recorded in compensation and benefits expense in the consolidated statements of income. Available-for-sale financial investments are comprised of the financial investments not held by the broker-dealer subsidiary,Cboe Trading, including highly liquid U.S. Treasury securities. Unrealized gains and losses, net of income taxes, are included as a component of accumulated other comprehensive income in the accompanying consolidated balance sheets. Interest on financial investments, including amortization of premiums and accretion of discounts, is recognized as income when earned. Realized gains and losses on financial investments are calculated using the specific identification method and are included in interest expense, net in the accompanying consolidated statements of income. A decline in the fair value of any available-for-sale investment below carrying amountvalue that is deemed to be other-than-temporary results in an impairment to reduce the carrying amountvalue to realizable value. To determine whether an impairment is other-than-temporary, the Company considers all available information relevant to the collectability of the investment, including past events, current conditions, and reasonable and supportable forecasts when developing estimate of cash flows expected to be collected. Evidence considered in this assessment includes the reasons for the impairment, the severity and duration of the impairment, changes in value subsequent to year-end, forecasted performance of the investee, and the general market condition in the geographic area or industry in which the investee operates. (f) Accounts Receivable, Net Accounts receivable are concentrated with the Company’s member firms and market data distributors and are carried at amortized cost. The Company nets transaction fees and liquidity payments for each member firm on a monthly basis and recognizes the total owed from a member firm as an assetaccounts receivable, net and the total owed to a member firm as a liability.accounts payable and accrued liabilities in the consolidated balance sheets. On a periodic basis, management evaluates the Company’s receivablesaccounts receivable and determinesrecords an appropriate allowance for uncollectibleexpected credit losses using an aging schedule. The aging schedule applies loss rates based on historical loss information and, as deemed necessary, is adjusted for differences in the nature of the receivables that exist at the reporting date from the historical period. Due to the short-term nature of the accounts receivable, basedchanges in future economic conditions are not expected to have a significant impact on anticipated collections. In circumstances where a specific customer’s inability to meet its financial obligations is probable, the Company records a specific provisionexpected credit losses. The accounts receivable are presented net of allowance for uncollectible accounts againstcredit losses on the consolidated balance sheets and the associated losses are presented in other operating expenses on the consolidated statements of income. 92103 Table of Contents amounts due to reduce the receivable to the amount the Company estimates will be collected. Once the Company determines an allowance for an uncollectible account is necessary, interest on the receivable ceases to be accrued. (g) Property and Equipment, Net Property and equipment, net is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated lives of the assets, generally ranging from three to seven years. Expenditures for repairs and maintenance are charged to expense as incurred. Depreciation of leasehold improvements is calculated using the straight-line method over the shorter of the related lease term or the estimated useful life of the assets. Long-lived assets to be held and used are reviewed to determine whether any events or changes in circumstances indicate that the carrying amountsvalues of the assets may not be recoverable. The Company bases this evaluation on such impairment indicators as the nature of the assets, the future economic benefit of the assets, any historical or future profitability measurements, as well as other external market conditions or factors that may be present. If such impairment indicators are present that would indicate that the carrying amountvalue of any asset may not be recoverable, the Company determines whether an impairment has occurred through the use of an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. In the event of impairment, the Company recognizes a loss for the difference between the carrying amountvalue and the estimated value of the asset as measured using quoted market prices or, in the absence of quoted market prices, a discounted cash flow analysis. The Company expenses software development costs as incurred during the preliminary project stage, while capitalizing costs incurred during the application development stage, which includes design, coding, installation and testing activities. (h) Goodwill and Intangible Assets, Net Goodwill represents the excess of purchase price over the value assigned to the net tangible and identifiable intangible assets of a business acquired. Goodwill is allocated to the Company’s reporting units based on the assignment of the fair values of each reporting unit of the acquired company. The Company tests goodwill for impairment at the reporting unit level annually, or in interim periods if certain events occur indicating that the carrying value may be impaired. The impairment test is performed during the fourth quarter using October 1st carrying values, and if the fair value of the reporting unit is found to be less than the carrying value, an impairment loss is recorded. The Company performed its 20192021 annual goodwill impairment test and determined that no0 impairment existed. Intangible assets, net, primarily include acquired trademarks and trade names, customer relationships, strategic alliance agreements, licenses and registrations and non-compete agreements. Intangible assets with finite lives are amortized based on the discounted cash flow method applied over the estimated useful lives of the intangible assets and are tested for impairment if certain events occur indicating that the carry value may be impaired. Intangible assets deemed to have indefinite useful lives are not amortized, but instead are tested for impairment at least annually, usually concurrently with goodwill. Impairment exists if the fair value of the asset is less than the carrying amount,value, and in that case, an impairment loss is recorded. The Company performed its 20192021 annual intangible assets impairment test using October 1, 20192021 carrying values and determined that 0 impairment existed. (i) Treasury Stock The Company accounts for the purchase of treasury stock under the cost method with the shares of stock repurchased reflected as a reduction to Cboe stockholders’ equity and included in common stock in treasury, at cost in the consolidated balance sheets. Shares repurchased under the Company’s share repurchase program are either available to be redistributed or they are retired. The Company accounts for the retirement of treasury stock by deducting its par value from common stock and reflecting any excess of cost over par value as a deduction from additional paid-in-capital on the consolidated balance sheets. (j) Foreign Currency The financial statements of foreign subsidiaries where the functional currency is not the U.S. dollar are translated into U.S. dollars using the exchange rate in effect as of each balance sheet date. Statements of income and cash flow amounts are translated using the average exchange rate during the period. The cumulative effects of translating the balance sheet accounts from the functional currency into the U.S. dollar at the applicable exchange rates are included in accumulated other comprehensive income (loss), net in the accompanying consolidated balance sheet.sheets. Foreign currency gains and losses are recorded as other (expense) income, net in the consolidated statements of income. The Company’s operations in the United Kingdom, Amsterdam, Canada, Singapore, andPhilippines, Hong Kong, are recorded in Pounds sterling, Singapore dollars,Australia and Hong Kong dollars, respectively.Japan are 93104 Table of Contents recorded in Pounds sterling, Euros, Canadian dollars, Singapore dollars, Philippine pesos, Hong Kong dollars, Australian dollars and Japanese Yen, respectively. (j)(k) Income Taxes Deferred taxes are recorded on a liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based upon the technical merits of the position. The tax benefit recognized in the consolidated financial statements from such a position is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Also, interest and penalties expense is recognized on the full amount of deferred benefits for uncertain tax positions. The Company’s policy is to include interest and penalties related to unrecognized tax benefits in the income tax provision within the consolidated statements of income. We haveThe Company elected to account for global intangible low-taxed income (“GILTI”) in the period in which it is incurred, and therefore, havehas not provided any deferred tax impacts of GILTI in ourthe consolidated financial statements. (k)(l) Revenue Recognition For further discussion related to revenue recognition of fees, such as transaction and clearing fees and liquidity payments, access and capacity fees, market data fees, and regulation transaction and Section 31 fees, see Note 4 (“Revenue Recognition”). Concentrations of Revenue and Liquidity Payments For the years ended December 31, 2021, 2020, and 2019, 2018, and 2017, 2 members accounted for 18%, 23%, and 17%, respectively, of the Company’s transaction fees. NaN member0 customer accounted for more than 15%13% of the Company’s total revenue during the years ended December 31, 2019, 2018, and 2017. For the years ended December 31, 2019, 2018, and 2017, revenue.0 member accounted for more than 15% of the Company’s liquidity payments. No membercustomer is contractually or otherwise obligated to continue to use the Company’s services. The loss of, or a significant reduction of, participation by these memberscustomers may have a material adverse effect on the Company’s business, financial position, results of operations and cash flows. The 2 largest clearing members mentioned above clear the majority of the market-maker sides of transactions at all of the Company’s U.S. options exchanges. If either of these clearing members were to withdraw from the business of market-maker clearing and market-makers were unable to transfer to another clearing member, this could create significant disruption to the U.S. options markets, including ours.Cboe’s. (l)(m) Earnings Per Share The computation of basic earnings per share is calculated by reducing net income for the period by dividends paid or declared and undistributed net income for the period that are allocated to participating securities to arrive at net income allocated to common stockholders. Net income allocated to common stockholders is divided by the weighted average number of common shares outstanding during the period to determine net income per share allocated to common stockholders. The computation of diluted earnings per share is calculated by dividing net income allocated to common stockholders by the sum of the weighted average number of common shares outstanding plus all additional common shares that would have been outstanding if the potentially dilutive common shares had been issued. The dilutive effect is calculated using the more dilutive of the two-class or treasury stock method. 94 Table of Contents (m)(n) Stock-Based Compensation The Company grants stock-based compensation to its employees through awards of restricted stock units. InAdditionally, in connection with the acquisition of Bats, Bats previously awardedthe Company inherited stock options and restricted stock awards.awards 105 Table of Contents that had been previously awarded by Bats. As all stock options were exercised in 2020, none were outstanding in 2021. The Company grants stock-based compensation to its employees through restricted stock units and grants restricted stock awards to its board members. The Company records stock-based compensation expense for all stock-based compensation granted based on the grant-date fair value. The Company recognizes stock-based compensation expense related to stock-based compensation awards with graded vesting that have a service condition on a straight-line basis over the requisite service period of the entire award. In connection with the acquisition of Bats, as discussed in Note 20 (“Stock-Based Compensation’) in further detail, each outstanding Bats stock option granted under any of the Bats Plans that was outstanding immediately prior to the effective time of the acquisition of Bats was converted into an option to purchase our common stock, on the same terms and conditions (including vesting schedule) as were applicable to such Bats stock option. All stock options are currently vested. In addition, each award of Bats restricted shares granted under any of the Bats Plans that was unvested immediately prior to the effective time of the acquisition of Bats was assumed by the Company and converted into an award of restricted shares of our common stock, subject to the same terms and conditions (including vesting schedule) that applied to the applicable Bats restricted shares.   The amount of stock-based compensation expense related to awards of restricted stock and restricted stock units is based on the fair value of Cboe Global Markets, Inc. common stock at the date of grant. The fair value is based on a current market-based transaction of the Company’s common stock. If a market-based transaction of the Company’s common stock is not available, then the fair value is based on an independent third-party valuation using equal weighting of two valuation analysis techniques, discounted cash flows and valuation multiples observed from publicly traded companies in a similar industry. (n)(o) Business Combinations The Company records identifiable assets, liabilities and goodwill acquired in a business combination at fair value at the acquisition date. Additionally, transaction-related costs are expensed in the period incurred. (o)(p) Debt Issuance Costs All costs incurred to issue debt are capitalized as a contra-liability and amortized over the life of the loandebt using the interest method. (p)(q) Cost and Equity Method Investments The Company usesgenerally accounts for investments using the cost method to accountmeasurement alternative when it owns less than 20% of the outstanding voting stock of a company, there is an absence of readily determinable fair value for a non-marketable equitythe respective investment, inand the Company has an entity that it does not control and for which it does not have the abilityinability to exercise significant influence over an entity’s operating and financial policies. When it does not have a controlling financial interest in an entity but can exercise significant influence over the entity's operating and financial policies, such investment is accounted for usingbased upon the equity method.respective ownership interests held. The Company recognizes dividend income when declared. In general, the equity method of accounting is used when the Company owns 20% to 50% of the outstanding voting stock of a company and when it is able to exercise significant influence over the operating and financial policies of a company. The Company has an investment where it has significant influence and as such accounts for the investments under the equity method of accounting. For equity method investments, the Company records the pro-rata share of earnings or losses each period and records any dividends received as a reduction in the investment balance. The equity method investment is evaluated forinclusive of other-than-temporary declines in value, recognized by consideringthe investee, who considers a variety of factors such as the earnings capacity of the investment and the fair value of the investment compared to its carrying amount.value. If the estimated fair value of the investment is less than the carrying amountvalue and the decline in value is considered to be other than temporary, the excess of the carrying amountvalue over the estimated fair value is recognized in the financial statements as an impairment. 95 Table of Contents (q)(r) Leases The Company determines if an arrangement contains a lease at inception. For arrangements where the Company is the lessee, operating leases are included in operating lease right of use (“ROU”) assets, accrued liabilities, and non-current operating lease liabilities on the balance sheet as of December 31, 2019.2021. The Company does not have any finance leases as of December 31, 2019.2021. ROU assets and operating lease liabilities are recognized based on the present value of the future lease payments over the lease term at commencement date. ROU assets also include any initial direct costs incurred and any lease payments made at or before the lease commencement date, less lease incentives received. The Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the lease liabilities, as the rate implicit in the Company’s leases are generally not reasonably determinable. Lease terms may include options to extend or terminate when the Company is reasonably certain that the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term. The Company also has lease arrangements with lease and non-lease components. The Company elected the practical expedient not to separate non-lease components from lease components for the Company’s leases. The Company elected to apply the short-term lease measurement and recognition exemption in which ROU assets and lease 106 Table of Contents liabilities are not recognized for short-term leases. For short-term operating leases, lease expense is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet and the Company recognizes lease expense in facilities costs within the consolidated statements of income for these leases on a straight-line basis over the lease term. Certain leases include one or more options to renew, with renewal terms that can extend the lease term from one to five years or more, and some of which include the Company’s option to terminate the leases within one year. When the implicit rate in the Company’s lease is not reasonably determinable, the Company applies an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. (s) Margin Deposits and Clearing Funds Margin deposits and clearing funds in the form of cash contributions by EuroCCP’s clearing participants where title has transferred to EuroCCP are included as current assets with equal and offsetting current liabilities in the consolidated balance sheet. These margin deposits and clearing funds are deposited with De Nederlandsche Bank (“DNB”), can only be used for specified EuroCCP operations, and fluctuate over time due to changes in deposit requirements. Certain non-cash margin deposits and clearing fund deposits, as well as interoperability fund deposits, are not reflected in the accompanying consolidated balance sheet, as EuroCCP does not take economic ownership of these balances. Cash held as margin deposits and clearing fund deposits may be invested at an approved bank in accordance with EuroCCP’s investment policy, and any interest or gain received, or loss incurred on invested funds is recorded in other revenue in the consolidated statements of income. 3.  RECENT ACCOUNTING PRONOUNCEMENTS Recent Accounting Pronouncements – Adopted In February 2016,December 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes. This ASU 2016-02, Leases. This update requires a lesseeremoved certain income tax exceptions and modifies existing guidance to recognize onsimplify the balance sheet a liability to make lease payments and a corresponding ROU asset. The guidance also requires certain qualitative and quantitative disclosures about the amount, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases ASU 2018-11, Leases (Topic 842) Targeted Improvements, ASU 2018-20, Leases (Topic 842) Narrow-Scope Improvementsaccounting for Lessors, and ASU 2019-01, Leases (Topic 842) Codification Improvements, to clarify the implementation guidance. This updated guidance provides an optional transition method, which allows for the initial application of the new accounting standard at the adoption date and the recognition of a cumulative-effect adjustment to the opening balance of retained earnings as of the beginning of the period of adoption. These updates are effective for annual and interim periods beginning after December 15, 2018. The Company adopted the new ASUs on January 1, 2019, using the alternative transition approach and will not restate comparative periods. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to not reassess contracts to determine if they contain leases, lease classification and initial direct costs. The Company’s application of the new standard resulted in changes to the balance sheet but did not have an impact on our consolidated income statements and statements of cash flows. See Note 25 (“Leases”) for more information. Recent Accounting Pronouncements - Issued, not yet Adopted In June 2016, the FASB issued ASU 2016-13, Credit Losses. This update replaces the incurred loss impairment methodology in current GAAP with a methodology that requires management to estimate an expected lifetime credit loss on financial assets. This includes loans, held-to-maturity debt securities, loan commitments, financial guarantees, and net investments in leases, as well as trade receivables. The update also amends the impairment model for available-for-sale debt securities. The forward-looking expected lifetime credit loss model generally will result in the earlier recognition of allowances for losses.taxes. For public entities, the update iswas effective for fiscal years and interim periodsperiod within those fiscal years, beginning after December 15, 2019, with early adoption permitted.2020. The Company adopted the newthis ASU on January 1, 2020 using the modified retrospective approach and will2021, which did not restate comparative periods. Upon the adoption of the standard, the Company expects to recognize an immaterial cumulative-effect adjustment to retained earnings for the expected lifetime credit loss on the financial instruments within the scope of the standard, including accounts 96 Table of Contents receivable, net. Based on the Company’s high turnover and collectability of accounts receivable, as well as the monthly billing process for the majority of revenue, the Company does not expect a significant varianceresult in the recognized loss between the incurred loss impairment methodology under the prior standard and the expected lifetime credit loss model under the update. The financial instruments other than accounts receivable, net that are within the scope of the standard are not materially impacted by the standard. The impact to the consolidated balance sheets is expected to be immaterial in nature and there is no expected impact on the consolidated income statements and statements of cash flows. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU removes certain disclosure requirements related to the fair value hierarchy, modifies existing disclosure requirements related to measurement uncertainty and adds new disclosure requirements. The new disclosure requirements include disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For public entities, the update is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019. The Company will adopt the update for the financial statements issued for the first quarter of 2020 and does not anticipate a material impact to the consolidated financial statements.statements and disclosures.

On February 28, 2017, pursuant to the Agreement and Plan of Merger, dated as of September 25, 2016 (the “Merger Agreement”), by and among Cboe, Bats, CBOE Corporation, a Delaware corporation and a wholly-owned subsidiary of Cboe (“Merger Sub”), and Cboe Bats, LLC (formerly CBOE V, LLC), a Delaware limited liability company and a wholly-owned subsidiary of Cboe (“Merger LLC”), Cboe completed the merger of Merger Sub with and into Bats and the subsequent merger of Bats with and into Merger LLC. As a result of the Merger, Bats became a wholly-owned subsidiary of Cboe. Other Acquisitions In January 2016, the Company, through its subsidiary Cboe Vest, LLC (“Cboe Vest”), acquired a majority of the outstanding equity of Vest, an asset investment manager focused on Target Outcome Investment strategies. The purchase price consisted of $18.9 million in cash, reflecting payments of $14.9 million to former stockholders and $4.0 million to Vest for newly issued shares, and represented an ownership interest of 60% resulting in the consolidation of Vest operations. The remaining 40% noncontrolling interest was held by the remaining Vest stockholders. The remaining Vest stockholders had a put option that could have been exercised to Vest and Vest had a call option that could have been exercised to the remaining stockholders. The put and call options could have been exercised after five years though they could have been accelerated by certain employment-related actions. The combination of the noncontrolling interest and a redemption feature resulted in a redeemable noncontrolling interest, which was classified outside of permanent equity on the consolidated balance sheet. The Company’s ownership interest decreased in August 2019 which resulted in the deconsolidation of Vest operations and the elimination of the redeemable noncontrolling interest. See Note 7 (“Investments”) for further information on the deconsolidation and Note 16 (“Redeemable Noncontrolling Interest”) for further information on the redeemable noncontrolling interest. In November 2017, the Company completed the acquisition of assets of Silexx Financial Systems, LLC (Silexx) for $9.0 million in cash. Silexx is a developer and operator of a multi-asset order and execution management system. Of the purchase price, $6.7 million was allocated to goodwill, $2.1 million was allocated to intangible assets, and $0.2 million was allocated to working capital. Silexx is included in the Options segment. The Company expensed $48.5 million of acquisition-related costs during the year ended December 31, 2019 that included $19.3 million of compensation-related costs, $10.5 million of impairment of goodwill charges, $6.1 million of impairment of facilities charges, $4.5 million loss on disposal of data processing software, $3.9 million of professional fees, $2.2 million of termination fees related to an assigned lease agreement, and $2.0 million of general and administrative expenses. These expenses relate to Bats and other acquisitions, and are included in acquisition-related costs in the consolidated statements of income. 99 Table of Contents The Company expensed $30.0 million of acquisition-related costs during the year ended December 31, 2018 that included $23.6 million of compensation-related costs, $2.7 million of stock based compensation, $3.0 million of professional fees, and $0.6 million of general and administrative expenses. These expenses relate to Bats and other acquisitions, and are included in acquisition-related costs in the consolidated statements of income. The Company expensed $84.4 million of acquisition-related costs during the year ended December 31, 2017 that included $44.2 million of compensation-related costs, $24.4 million of professional fees, $14.9 million of an impairment of capitalized data processing software, and $0.9 million of facilities expenses. These expenses relate to Bats and other acquisitions, and are included in acquisition-related costs in the consolidated statements of income. 6.  SEVERANCE Subsequent to the Bats acquisition, the Company determined that certain employees' positions were redundant. As such, the Company communicated employee termination benefits to these employees. The following is a summary of the employee termination benefits recognized within compensation and benefits in the consolidated statements of income (in millions): ​ ​ ​ ​ ​ ​      Employee Termination Benefits   Balance at December 31, 2018 ​ $ 6.1 ​ Termination benefits accrued ​   10.7 ​ Termination payments made ​   (10.1) ​ Balance at December 31, 2019 ​ $ 6.7 ​ ​ ​ 7.  INVESTMENTS As of December 31, 2019 and 2018, the Company's investments were comprised of the following (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31,  ​      2019      2018 Equity method investments: ​ ​ ​ ​ ​ ​ Investment in Signal Trading Systems, LLC ​ $ 12.6 ​ $ 12.4 Investment in EuroCCP ​   10.3 ​   9.3 Total equity method investments ​ ​ 22.9 ​ ​ 21.7 ​ ​ ​ ​ ​ ​ ​ Cost method investments: ​ ​ ​ ​ ​ ​ Investment in OCC ​ ​ 0.3 ​ ​ 30.3 Investment in Eris Exchange Holdings, LLC ​ ​ 20.8 ​ ​ 20.0 Investment in American Financial Exchange, LLC ​ ​ 8.6 ​ ​ 5.9 Investment in Cboe Vest Financial Group, Inc. ​ ​ 2.9 ​ ​ — Other cost method investments ​   5.7 ​   8.3 Total cost method investments ​ ​ 38.3 ​ ​ 64.5 ​ ​ ​ ​ ​ ​ ​ Total investments ​ $ 61.2 ​ $ 86.2 ​ Equity Method Investments Equity method investments include investments in Signal Trading Systems, LLC, a 50% joint venture with FlexTrade System, Inc. to develop and market a multi-asset front-end order entry system, and EuroCCP, a Dutch domiciled clearing house. EuroCCP is one of 3 interoperable central counterparties, or CCPs, used to clear trades 100 Table of Contents conducted on Cboe Europe Limited’s and Cboe Europe NL’s markets. Cboe Europe Limited owns 20% of EuroCCP and can exercise significant influence over the entity as an equal shareholder with 4 other investors. Cost Method Investments The carrying amount of cost method investments totaled $38.3 million and $64.5 million as of December 31, 2019 and 2018, respectively, and is included in investments in the consolidated balance sheets. The Company accounts for these investments using the measurement alternative primarily as a result of the Company's inability to exercise significant influence as the Company is a smaller shareholder of these investments and the lack of readily determinable fair values. As of December 31, 2019, cost method investments primarily reflect a 20% investment in OCC and minority investments in American Financial Exchange, LLC, CurveGlobal, Vest, and Eris Exchange Holdings, LLC. In December 2014, OCC announced a newly-formed capital plan, under which each of OCC's existing exchange stockholders agreed to contribute its pro-rata share, based on ownership percentage, of $150 million in equity capital, which would increase OCC's shareholders' equity, and to provide its pro rata share in replenishment capital, up to a maximum of $40 million per exchange stockholder, if certain capital thresholds were to be breached. OCC also adopted policies under the plan with respect to fees, customer refunds, and stockholder dividends, which envisioned an annual dividend payment to the exchange stockholders. On March 3, 2015, in accordance with the plan, Cboe Options contributed $30 million to OCC. That contribution was recorded under investments in the consolidated balance sheets as of December 31, 2018. In 2019, OCC did not disburse annual dividends under the capital plan. In 2018 and 2017, OCC disbursed annual dividends under the capital plan and the Company, via its ownership interests, received $6.0 million in 2018 and $5.0 million in 2017. The SEC initially issued a notice of no objection to OCC’s advance notice filing regarding the capital plan and subsequently approved OCC’s proposed rule filing for the capital plan, but certain petitioners appealed the SEC approval order to the U.S. Court of Appeals for the D.C. Circuit. The court ultimately remanded the matter to the SEC, and on February 13, 2019, the SEC issued an order disapproving the proposed rule change implementing OCC’s capital plan. In an effort to achieve compliance with its target capital requirements in the absence of an approved capital plan, OCC has (i) retained funds that otherwise would have been paid to stockholders as dividends and to clearing members as refunds with respect to 2018, and (ii) raised its clearing fees. In connection with the disapproval of the capital plan, OCC returned the capital that had been contributed by its shareholders under the disapproved plan (equal to $30.0 million for Cboe Options) to the respective shareholders in 2019, of which $22.0 million was returned to Cboe Options in the first quarter of 2019 and $8.0 million in the fourth quarter of 2019. With each return of capital described in this paragraph, the Company also incurred a tax expense. OCC agreed to reimburse the Company for part of that tax liability and paid the Company $1.1 million in the third quarter and $0.4 million in the fourth quarter of 2019. OCC did not pay its shareholders any dividend or other return on the retained portion of their capital contributions. As such, the Company reversed the $8.8 million OCC dividend declared in 2018, which was to be paid in 2019, in other income in the consolidated statement of income for the year ended December 31, 2019. The remaining contributed capital has been recorded under investments in the consolidated balance sheet as of December 31, 2019. On January 24, 2020, upon receipt of SEC approval, OCC established a new capital management policy intended to replace the disapproved capital plan. The new capital management policy provides that, if OCC’s equity capital falls below certain defined thresholds, OCC can access additional capital through an operational loss fee charged to clearing members. None of OCC’s shareholders (including Cboe Options) has any obligation to contribute capital to OCC under the new capital management policy, nor does any shareholder have the right to receive dividends from OCC under such policy. In August 2019, the Company’s ownership in Vest was restructured, including a partial sale of its interest to a third-party. As a result of the restructuring, the Company’s ownership and voting interests decreased to less than 20% and less than 5%, respectively, and the Company deconsolidated Vest and changed the accounting methodology of the investment to the cost method. The deconsolidation resulted in a reduction of net assets of $14.5 million and noncontrolling interest of $5.8 million, as well as recognition of $2.9 million investment for the Company’s remaining ownership. The Company recorded an interest-bearing note receivable of $3.7 million for the consideration received from the third-party, which was recognized in other assets, net in the consolidated balance sheet as of December 31, 2019. Additionally, a loss on the sale of $2.0 million was recognized in acquisition-related costs in the consolidated statement of income for the year ended December 31, 2019. See Note 11 (“Goodwill and Intangibles, Net”) for further discussion of the Vest restructuring. 101 Table of Contents In the third quarter of 2019, the Company fulfilled a contractual obligation to American Financial Exchange, LLC to launch AMERIBOR futures. As a result of the fulfillment, an additional 5% ownership of American Financial Exchange, LLC was earned by the Company for an additional investment of $2.7 million. The additional revenue was recorded in the Futures segment and increased the Company’s investment in American Financial Exchange, LLC. 8.  FINANCIAL INVESTMENTS The Company’s financial investments with original or acquired maturities longer than three months, but that mature in less than one year from the balance sheet date and any money market funds that are considered cash and cash equivalents are classified as current assets.

As a result of the Merger, there is a reduction in employee workspace needed in Chicago, which led to the decision to market for sale the headquarters location. The Company classified the associated land, building, and certain furniture and equipment of the headquarters location as held for sale, performed an impairment assessment, and ceased depreciation effective May 1, 2019, as the Company anticipates selling the property held for sale in less than twelve months. As of December 31, 2019, the total value of the property classified as property held for sale on the consolidated balance sheet was $21.1 million. The impact of ceasing depreciation of the property held for sale did not result in a material impact to the consolidated financial statements. As a result of the impairment assessment, an impairment charge of $6.1 million was recorded in acquisition-related costs within the Options segment in the accompanying consolidated statements of income. 102 Table of Contents 10.  OTHER ASSETS, NET Other assets, net consisted of the following as of December 31, 2019 and 2018 (in millions): ​ ​ ​ ​ ​ ​ ​ ​      December 31,       December 31,  ​ ​ 2019 ​ 2018 Software development work in progress ​ $ 2.6 ​ $ 8.7 Data processing software (1) ​ ​ 84.3 ​ ​ 219.0 Less accumulated depreciation and amortization ​   (57.2) ​   (193.2) Data processing software, net ​   29.7 ​   34.5 Other assets (2) ​ ​ 21.9 ​ ​ 28.4 Data processing software and other assets, net ​ $ 51.6 ​ $ 62.9 (1) During the fourth quarter of 2019, the Company disposed of data processing software for the technology platform known as Cboe Command, as Cboe Options was migrated to the Company’s current platform on October 7, 2019. As a result of the disposal, a loss on disposal of $4.5 million was recorded in acquisition-related costs within the Options segment in the accompanying consolidated statements of income. (2) At December 31, 2019 and December 31, 2018, the majority of the balance included long-term prepaid assets and notes receivable. The notes receivable included within other assets, net on the consolidated balance sheets relate to the consolidated audit trail (“CAT”), which involves the creation of a comprehensive audit trail that strives to enhance regulators’ ability to monitor trading activity in the U.S. markets through a phased implementation. While the funding of the CAT is ultimately expected to be provided by both SROs (which includes the Exchanges) and industry members, until fee filings associated with the funding model are effective with or approved by the SEC, the funding to date has solely been provided by the SROs. The funding by the SROs has been done in exchange for promissory notes, which are expected to be repaid once such industry member fees are collected. Until the fee filings associated with the funding model are effective with or approved by the SEC, the SROs may continue to incur additional significant costs. Due to circumstances associated with the development of the CAT in the fourth quarter of 2019, the Company estimated a loss associated with the uncollectibility of the promissory notes, and recorded a provision for the notes receivable of $23.4 million. As of December 31, 2019 and December 31, 2018, the notes receivable, net balance was $9.2 million and $20.3 million, respectively. ​ Amortization expense related to data processing software was $13.5 million, $18.9 million, and $17.9 million for the years ended December 31, 2019, 2018, and 2017. 11.  GOODWILL AND INTANGIBLE ASSETS, NET The following table presents the details of goodwill by segment (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. ​ European ​ ​ ​ ​ Corporate ​ ​ ​   ​      Options      Equities      Equities      Global FX      and Other      Total   Balance as of December 31, 2017 ​ $ 239.4 ​ $ 1,740.4 ​ $ 441.6 ​ $ 267.2 ​ $ 18.8 ​ $ 2,707.4 ​ Additions ​   — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​   — ​ Dispositions ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ Changes in foreign currency exchange rates ​   — ​   — ​   (16.0) ​   — ​   — ​   (16.0) ​ Balance as of December 31, 2018 ​ $ 239.4 ​ $ 1,740.4 ​ $ 425.6 ​ $ 267.2 ​ $ 18.8 ​ $ 2,691.4 ​ Additions ​   — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​   — ​ Dispositions ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ (8.3) ​ ​ (8.3) ​ Impairment ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ (10.5) ​ ​ (10.5) ​ Changes in foreign currency exchange rates ​   — ​ ​ — ​ ​ 9.5 ​ ​ — ​ ​ — ​   9.5 ​ Balance as of December 31, 2019 ​ $ 239.4 ​ $ 1,740.4 ​ $ 435.1 ​ $ 267.2 ​ $ — ​ $ 2,682.1 ​ ​ 103108 Table of Contents Goodwill has been allocated to specific reporting units for purposes of impairment testing - Options, U.S. Equities, European Equities and Global FX.

These acquisition-related expenses are included in acquisition-related costs in the consolidated statements of income. ​ ​ 6.  INVESTMENTS As of December 31, 2021 and 2020, the Company's investments were comprised of the following (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31,  ​      2021      2020 Equity method investments: ​ ​ ​ ​ ​ ​ Investment in Signal Trading Systems, LLC ​ $ — ​ $ 2.0 Investment in 7Ridge Investments 3 LP ​ ​ 209.5 ​ ​ — Total equity method investments ​ ​ 209.5 ​ ​ 2.0 ​ ​ ​ ​ ​ ​ ​ Other equity investments: ​ ​ ​ ​ ​ ​ Investment in Eris Exchange Holdings, LLC ​ ​ 20.0 ​ ​ 20.0 Investment in American Financial Exchange, LLC ​ ​ 10.6 ​ ​ 10.6 Investment in Cboe Vest Financial Group, Inc. ​ ​ 2.9 ​ ​ 2.9 Investment in Eris Digital Holdings, LLC ​ ​ 1.1 ​ ​ 0.8 Investment in OCC ​ ​ 0.3 ​ ​ 0.3 Other equity investments ​   1.4 ​   6.1 Total other equity investments ​ ​ 36.3 ​ ​ 40.7 ​ ​ ​ ​ ​ ​ ​ Total investments ​ $ 245.8 ​ $ 42.7 ​ Equity Method Investments Equity method investments included investments in Signal Trading Systems, LLC (“Signal”), a 50% joint venture with FlexTrade System, Inc. (“FlexTrade”) to develop and market PULSe, a multi-asset front-end order entry system. In 2020, the Company commenced an initiative to migrate PULSe, and its related activity to Cboe Silexx, LLC, a wholly-owned subsidiary of the Company. PULSe was decommissioned as of December 31, 2020, and the joint venture with FlexTrade was wound down during the first quarter of 2021. The Company concluded that the remaining investment in Signal had no future economic value and the remaining balance was written off as of March 31, 2021. The loss related to the write-off was included within acquisition-related costs in the consolidated statements of income. On October 31, 2021, the Company, through a wholly-owned subsidiary, became a limited partner of 7Ridge Investments 3 LP (“7Ridge Fund”) in connection with 7Ridge Fund’s planned acquisition of Trading Technologies International, Inc. (“Trading Technologies”). On December 13, 2021, the Company’s subsidiary provided its financial commitment to 7Ridge Fund, and on December 21, 2021, 7Ridge Fund completed the acquisition of Trading Technologies. Trading Technologies is a global provider of next-generation professional trading software, connectivity and data solutions. The Company is strategically aligned with Trading Technologies’ vision of delivering a leading trading, connectivity and data network to the global trading community. The Company’s investment in the 7Ridge Fund, represents a nonconsolidated variable interest entity (“VIE”). The Company has determined that consolidation of the VIE is not required as the Company is not the primary beneficiary of the 7Ridge Fund, as it does not have controlling financial interest and lacks the ability to unilaterally remove the general partner, 7Ridge Investments 3 GP Limited, direct material strategic decisions, or dissolve the entity (i.e. the Company does not have unilateral substantive “kick-out” or “liquidation” rights). ​ 111 Table of Contents The Company’s interest in the 7Ridge Fund investment is equal to the carrying value of the investment as of December 31, 2021, or $209.5 million, which is included in investments within the consolidated balance sheets. The Company’s maximum loss exposure, in the unlikely event that all of the VIE’s assets become worthless, is limited to the carrying value of Company’s investment. Other Equity Investments The carrying value of other equity investments is included in investments in the consolidated balance sheets. The Company accounts for these investments using the measurement alternative given the absence of readily determinable fair values for the respective investments and due to the Company’s inability to exercise significant influence over the investments based upon the respective ownership interests held. As of December 31, 2021, other equity investments primarily reflect a 20% investment in OCC and minority investments in Eris Exchange Holdings, LLC, American Financial Exchange, LLC, and Cboe Vest Financial Group, Inc. In January 2016, the Company, through its subsidiary Cboe Vest, LLC (“Cboe Vest”), acquired a majority of the outstanding equity of Vest, an asset investment manager focused on Target Outcome Investment strategies. The purchase price consisted of $18.9 million in cash, reflecting payments of $14.9 million to former stockholders and $4.0 million to Vest for newly issued shares, and represented an ownership interest of 60% resulting in the consolidation of Vest operations. The remaining 40% noncontrolling interest was held by the remaining Vest stockholders. The remaining Vest stockholders had a put option that could have been exercised to Vest and Vest had a call option that could have been exercised to the remaining stockholders. The put and call options could have been exercised after five years though they could have been accelerated by certain employment-related actions. The combination of the noncontrolling interest and a redemption feature resulted in a redeemable noncontrolling interest, which was classified outside of permanent equity on the consolidated balance sheet. The Company’s ownership interest decreased in August 2019 which resulted in the deconsolidation of Vest operations and the elimination of the redeemable noncontrolling interest. In May 2020, Eris Exchange Holdings, LLC completed a restructuring transaction to spin out Eris Digital Holdings, LLC into a stand-alone entity. The restructuring qualifies as an exchange of ownership interest, though it required no additional consideration exchanged to execute the exchange of units. The restructuring did not result in a change in number of units owned by the Company or a substantial change in the Company’s ownership interest percentage. NaN gain or loss is recognized as a result of the restructuring.As discussed below, on October 19, 2021, the Company entered into an agreement to acquire all of the outstanding equity interests of Eris Digital Holdings, LLC. However, Eris Exchange Holdings, LLC is not a part of this transaction and the Company retains its minority equity ownership interest in Eris Exchange Holdings, LLC. In August 2020, the Company recorded within acquisition-related costs in the consolidated statements of income an impairment charge of $4.1 million on its investment in AFX based on management’s assessment of the fair value of the investment. On September 21, 2021, CurveGlobal Limited (“CurveGlobal”), a minority investment of the Company included within other equity investments, announced plans to wind down the company in January 2022. The Company concluded that the remaining investment in CurveGlobal had no future economic value, and thus, wrote off the investment as of September 30, 2021. CurveGlobal ceased operations on January 28, 2022. The loss related to the write-off was included within other (expense) income, net in the consolidated statements of income. As announced on October 20, 2021, the Company plans to acquire the remaining interest in Eris Digital Holdings, LLC. The closing of the transaction is subject to regulatory review and other customary closing conditions. As a result, the timing of the closing is uncertain, but the Company presently anticipates a closing in the first half of 2022.

As a result of the Merger, there was a reduction in employee workspace needed in Chicago, which led to the decision to market for sale the headquarters location. The Company classified the associated land, building, and certain furniture and equipment of the headquarters location as held for sale, performed an impairment assessment, and ceased depreciation effective May 1, 2019, as the Company anticipated selling the property held for sale in less than twelve months. As of December 31, 2021, the headquarters location remains on the market for sale and management’s intent to sell the property is unchanged. However, due to the time elapsed since active marketing for sale of the building commenced, the Company has reclassified the property to held and used, effective May 1, 2021, and the building was once again subject to depreciation. The total value of the property classified as property held and used was $11.7 million, which includes $2.3 million of land and $9.4 million of property and equipment, net on the consolidated balance sheet as of December 31, 2021. As a result of the headquarters location’s classification as held for sale during the second quarter of 2020, an impairment assessment was performed and an additional impairment charge of $8.1 million was recorded in acquisition related costs within the Options segment in the accompanying consolidated statements of income. 8.  CREDIT LOSSES Current expected credit losses are estimated for accounts receivable and certain notes receivable. The notes receivable included within other assets, net on the consolidated balance sheets primarily relate to the consolidated audit trail (“CAT”), which involves the creation of an audit trail that strives to enhance regulators’ ability to monitor trading activity in the U.S. markets through a phased implementation. The funding of the CAT is ultimately expected to be provided by both self-regulatory organizations (“SROs”) (which includes the Exchanges) and industry members; however, the funding to date has solely been provided by the SROs in exchange for promissory notes, which are expected to be repaid once fee filings and plan amendments associated with a funding model are approved by the SEC and such industry member fees are collected. Until those fees are collected, the SROs may continue to incur additional significant costs, including additional promissory notes to fund CAT operations. The allowance for notes receivable credit losses associated with the CAT are calculated using a probability of default methodology that is primarily based on various potential outcomes of the funding model proposals being discussed with the SEC. Accounts receivable represent amounts due from the Company’s member firms. The allowance for accounts receivable credit losses is calculated using an aging schedule. The following represents the changes in allowance for credit losses for the year ended December 31, 2021 (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at January 1, 2021 ​ Current period provision for expected credit losses ​ Write-offs charged against the allowance ​ Recoveries collected ​ Balance at December 31, 2021 Allowance for notes receivable credit losses ​ $ 30.1 ​ $ — ​ $ — ​ $ — ​ $ 30.1 Allowance for accounts receivable credit losses ​ ​ 0.6 ​ ​ 0.7 ​ ​ (0.3) ​ ​ — ​ ​ 1.0 Total allowance for credit losses ​ $ 30.7 ​ $ 0.7 ​ $ (0.3) ​ $ — ​ $ 31.1 ​ 113 Table of Contents 9.  OTHER ASSETS, NET Other assets, net consisted of the following as of December 31, 2021 and 2020 (in millions): ​ ​ ​ ​ ​ ​ ​ ​      December 31,       December 31,  ​ ​ 2021 ​ 2020 Software development work in progress ​ $ 5.6 ​ $ 8.4 Data processing software ​ ​ 103.8 ​ ​ 92.6 Less accumulated depreciation and amortization ​   (70.9) ​   (63.5) Data processing software, net ​   38.5 ​   37.5 Other assets (1) ​ ​ 87.3 ​ ​ 38.8 Other assets, net ​ $ 125.8 ​ $ 76.3 (1) At December 31, 2021 and December 31, 2020, the majority of the balance included long-term prepaid assets and notes receivable.

Loans under the Term Loan Agreement bear interest, at ourthe Company’s option, at either (i) the London Interbank Offered Rate (“LIBOR”) periodically fixed for an interest period (as selected by us)the Company) of one, two, three or six months plus a margin (based on ourthe Company’s public debt ratings) ranging from 1.00 percent per annum to 1.50 percent per annum or (ii) a daily floating 105 Table of Contents rate based on the agent’s prime rate (subject to certain minimums based upon the federal funds effective rate or LIBOR) plus a margin (based on ourthe Company’s public debt ratings) ranging from 0 percent per annum to 0.50 percent per annum. The Company was required to pay an up-front fee of 0.05 percent to the agent for the entry into the Term Loan Agreement. On May 29, 2020, the Company amended the Term Loan Agreement to, among other items, (i) permit liens on assets of the EuroCCP settlement and clearing business that secures indebtedness incurred in support of its settlement and clearing activities, and permit the Company’s subsidiaries to incur such indebtedness, provided that such amounts are repaid within 35 days; and (ii) provide that LIBOR, as used in the Term Loan Agreement, may be succeeded by one or more secured overnight financing rates (“SOFR”) published by the Federal Reserve Bank of New York or another alternate benchmark rate giving due consideration to any evolving or then-existing convention for similar agreements. On June 25, 2021, the Company further amended the Term Loan Agreement to, among other items, (i) extend the maturity date from December 15, 2021 to December 15, 2023; (ii) allow for an additional draw of $110 million, which the Company borrowed on June 25, 2021 in order to fund a portion of the previously announced acquisition of Chi-X Asia Pacific; (iii) modify the applicable margin paid on the loans to 65 basis points regardless of the Company’s debt rating; (iv) add LIBOR replacement provisions, generally transitioning to a hardwired approach based on SOFR, with certain adjustments as further described in the amendment; (v) increase the amount of indebtedness certain subsidiaries may incur from the greater of $250 million and 35% consolidated EBITDA for four consecutive quarters to the greater of $350 million and 35% consolidated EBITDA for four consecutive quarters; (vi) allow the Company to increase the maximum permitted consolidated leverage ratio to 4.00 to 1.00 (from 3.50 to 1.00) for four consecutive fiscal quarters following certain acquisitions, provided this increase may be made only once; and (vii) modify certain other provisions to be consistent with the Company’s Revolving Credit Agreement (as defined below). The Term Loan Agreement, which matures on December 15, 2021,2023, contains customary representations, warranties and affirmative and negative covenants for facilities of its type, including financial covenants, events of default, including cross-defaults from the Company’s other indebtedness, and indemnification provisions in favor of the lenders thereunder. The negative covenants include restrictions regarding the incurrence of liens, the incurrence of indebtedness by ourthe Company’s subsidiaries and fundamental changes, subject to certain exceptions in each case. The financial covenants require usthe Company to meet a quarterly financial test with respect to a minimum consolidated interest coverage ratio of not less than 4.00 to 1.00 and a maximum consolidated leverage ratio of not greater than 3.50 to 1.00.

The Company repaid $50 million of the outstanding indebtedness of the Term Loan Agreement with cash on hand during the year ended December 31, 2019. Senior Notes  On January 12, 2017, the Company entered into an indenture (the “Indenture”), by and between the Company and Wells Fargo Bank, National Association, as trustee, in connection with the issuance of $650 million aggregate principal amount of the Company’s 3.650% Senior Notes due 2027 ("(“3.650% Senior Notes" or the “Senior Notes”, as the context so requires)). The form and terms of the 3.650% Senior Notes were established pursuant to an Officer’s Certificate, dated as of January 12, 2017, supplementing the Indenture. The Company used a portion of the net proceeds from the 3.650% Senior Notes to fund, in part, the Merger, including the payment of related fees and expenses and the repayment of Bats’ existing indebtedness, and the remainder for general corporate purposes. The 3.650% Senior Notes mature on January 12, 2027 and bear interest at the rate of 3.650% per annum, payable semi-annually in arrears on January 12 and July 12 of each year, commencing July 12, 2017. 116 Table of Contents On June 29, 2017,December 15, 2020, the Company issued $300$500 million aggregate principal amount of 1.950%1.625% Senior Notes due 2019 (“1.950%2030 ("1.625% Senior Notes”Notes" and, together with the 3.650% Senior Notes, the “Senior Notes”"Senior Notes"),. The form and terms of the 1.625% Senior Notes were established pursuant to an Officer’s Certificate, dated as of December 15, 2020, supplementing the Indenture.

The Senior Notes are unsecured obligations of the Company and rank equally with all of the Company’s other existing and future unsecured, senior indebtedness, but are effectively junior to the Company’s secured indebtedness, to the extent of the value of the assets securing such indebtedness, and will be structurally subordinated to the secured and unsecured indebtedness of the Company’s subsidiaries. The Company has the option to redeem some or all of the Senior Notes, at any time in whole or from time to time in part, at the redemption prices set forth in the applicable Officer’s Certificate. The Company may also be required to offer to repurchase the Senior Notes upon the occurrence of a Change of Control Triggering Event (as such term is defined in the applicable Officer’s Certificate) at a repurchase price equal to 101% of the aggregate principal amount of Senior Notes to be repurchased. The Company repaid the aggregate principal amount of the 1.950% Senior Notes in full with cash on hand upon their maturity on June 28, 2019. Indenture Under the Indenture, the Company may issue debt securities, which includes the 3.650% Senior Notes and the 1.625% Senior Notes, at any time and from time to time, in one or more series without limitation on the aggregate principal amount. The Indenture governing the 3.650% Senior Notes and the 1.625% Senior Notes contains customary restrictions, including a limitation that restricts ourthe Company’s ability and the ability of certain of ourthe Company’s subsidiaries to create or incur secured debt.

The Company may also, subject to the agreement of the applicable lenders, increase the commitments under the Revolving Credit Facility by up to $100 million, for a total of $250$350 million. Subject to specified conditions, the Company may designate 1 or more of its subsidiaries as additional borrowers under the Revolving Credit Agreement provided that the Company guarantees all borrowings and other obligations of any such subsidiaries.subsidiaries under the Revolving Credit Agreement. As of December 31, 2019,2021, 0 subsidiaries were designated as additional borrowers. Funds borrowed under the Revolving Credit Agreement may be used to fund working capital and for other general corporate purposes.purposes, including the making of any acquisitions the Company may pursue in the ordinary course of its business. As of December 31, 2019,2021, 0 borrowings were outstanding under the Revolving Credit Agreement. Accordingly, at December 31, 2019, $1502021, $250 million of borrowing capacity was available for the purposes permitted by the Revolving Credit Agreement. Loans under the Revolving Credit Agreement will bear interest, at ourthe Company’s option, at either (i) LIBOR periodically fixed for an interest period (as selected by us) of one, two, three or six months plus a margin (based on ourthe Company’s public debt ratings) ranging from 1.000.875 percent per annum to 1.751.50 percent per annum or (ii) a daily floating rate based on ourthe agent’s prime rate (subject to certain minimums based upon the federal funds effective rate or LIBOR) plus a margin (based on ourthe Company’s public debt ratings) ranging from 0 percent per annum to 0.750.50 percent per annum. The Revolving Credit Agreement includes a mechanism to replace LIBOR with an alternate benchmark rate that includes the forward-looking term rate for any interest period that is based on the SOFR 117 Table of Contents published by the Federal Reserve Bank of New York, as may be adjusted pursuant to the terms of the Revolving Credit Agreement. Subject to certain conditions stated in the Revolving Credit Agreement, the Company and any subsidiaries designated as additional borrowers may borrow, prepay and reborrow amounts under the Revolving Credit Facility at any time during the term of the Revolving Credit Agreement. The Revolving Credit Agreement will terminate and all amounts owing thereunder will be due and payable on December 15, 2021,21, 2023, unless the commitments are terminated earlier, either at ourthe request of the Company or, if an event of default occurs, by the Revolving Lenders (or automatically in the case of certain bankruptcy-related events).

CLEARING OPERATIONS EuroCCP is a European equities central counterparty that provides post-trade services to stock exchanges, MTFs over-the-counter (“OTC”) equities trades, and an equity index derivatives exchange. EuroCCP clears equities from 18 European markets and the United States, as well as Depositary Receipts, ETFs, and exchange traded 119 Table of Contents currencies (“ETCs”). In September, 2021 EuroCCP began clearing equity index derivatives for 6 European markets. Through a novation process, EuroCCP becomes the buyer for every seller and the seller for every buyer, thereby protecting clearing participants from counterparty risk and allowing the settlement of trades in the event of a clearing participant default. EuroCCP only assumes the guarantor role if it has an equal and offsetting claim against a clearing participant. For the period ended December 31, 2021, there have been no events of default for which a liability is required to be recognized in accordance with GAAP. Clearing Participant Deposits EuroCCP generally requires all clearing participants to deposit collateral to help mitigate EuroCCP’s exposure to credit risk in the event that a clearing participant fails to meet a financial or contractual obligation. Margin Deposits Margin deposits, which are predominately in the form of cash and cash equivalents, are deposits made by each clearing participant to EuroCCP to cover some or all of the credit risk of its failure to fulfill its obligations in the trade. EuroCCP maintains and manages all cash deposits related to margin deposits. Substantially all risks and rewards of margin deposit ownership, including net interest income, belong to EuroCCP and are recorded in other revenue on the consolidated statements of income. In the event of a default, EuroCCP can access the defaulting participant’s margin deposits to cover the defaulting participant’s losses. For more information, see “Default and Liquidity Waterfalls” below. Clearing Funds The clearing fund mutualizes the risk of default among all clearing participants. Depending on their membership, clearing participants contribute to the cash-equity and/or derivatives segment of the clearing fund. Although the entire clearing fund is available to cover potential losses in the event that the margin deposits and the clearing fund deposits of a defaulting clearing participant are inadequate to fulfill that clearing participant’s outstanding financial obligations, the clearing fund first uses the product class segment of the Clearing Fund in which the defaulting participants was active (see Default and Liquidity Waterfalls below). In the event of a default, EuroCCP is generally required to liquidate the defaulting clearing participant’s open positions. To the extent that the positions remain open, EuroCCP is required to assume the defaulting clearing participant’s obligations related to the open positions. Clearing participants are required to make contributions to the clearing fund that are proportional to their risk exposure in the form of cash or non-cash contributions, which generally consist of highly liquid securities.   Interoperability Fund For the cash equity business line, EuroCCP has entered into interoperable arrangements with 2 other central counterparties (“CCPs”). Under these arrangements, margin is paid to, and received from, the other CCPs. The interoperability fund consists of collateral pledged by EuroCCP to the other interoperable CCPs, to cover margin calls EuroCCP received from other interoperable CCPs. For EuroCCP, the collateral pledged by the clearing participants is maintained in an interoperability fund designated account. EuroCCP does not have any economic interest or ownership in the collateral; therefore, these balances are not included in the consolidated balance sheet. 120 Table of Contents The following tables present the Company’s total clearing participant deposits as of December 31, 2021 and December 31, 2020 (in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ Cash Contributions      Non-Cash Contributions (1)      Total Contributions Margin deposits ​ $ 600.0 ​ $ 287.0 ​ $ 887.0 Clearing funds ​ ​ 145.9 ​ ​ 41.9 ​ ​ 187.8 Interoperability funds (1) ​ ​ 423.3 ​ ​ 92.6 ​ ​ 515.9 Total ​ $ 1,169.2 ​ $ 421.5 ​ $ 1,590.7 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ Cash Contributions      Non-Cash Contributions (1)      Total Contributions Margin deposits ​ $ 319.5 ​ $ 401.0 ​ $ 720.5 Clearing funds ​ ​ 492.6 ​ ​ 69.7 ​ ​ 562.3 Interoperability funds (1) ​ ​ 378.5 ​ ​ 175.2 ​ ​ 553.7 Total ​ $ 1,190.6 ​ $ 645.9 ​ $ 1,836.5 (1) These amounts are not reflected in the consolidated balance sheet, as EuroCCP does not take economic ownership of these balances. ​ Default and Liquidity Waterfalls The default waterfall is the priority order in which the capital resources are expected to be utilized in the event of a default where the defaulting clearing participant’s collateral would not be sufficient to cover the cost to liquidate its portfolio. If a default occurs and the defaulting clearing participant’s collateral, including margin deposits and clearing fund deposits, are depleted, then additional capital is utilized in the following order: • EuroCCP dedicated own resources: The EuroCCP default waterfall first utilizes its own dedicated resources ahead of clearing fund contributions of non-defaulting clearing participants, up to 25% of EuroCCP capital requirements discussed in Note 18 (“Regulatory Capital”). • Clearing fund: Second, the EuroCCP default waterfall utilizes traditional CCP risk mutualization, in the event that default losses fully exhaust EuroCCP’s dedicated own resources amount, whereby contributions applicable to a particular product class are applied first to any loss attributable to that product class. • Pro rata contributions: Third, if the default losses caused cannot be covered by the first two layers, the non-defaulting clearing participants shall on demand make additional payments to EuroCCP on a pro rata basis in proportion to the amount of their clearing fund contributions to cover any such remaining losses, which is limited to an amount equal to twice their clearing fund contribution as established under EuroCCP’s rules and regulations. In this scenario, contributions applicable to a particular product class are first applied to any losses attributable to that product class. In addition to the default waterfall, the liquidity waterfall is the priority order in which the liquidity resources are expected to be utilized for EuroCCP’s ordinary course business operations and in situations when additional liquidity resources and liquidity measures may be activated in case of a potential liquidity shortfall. Liquidity, intraday or overnight, is mainly required for securities settlement. In ordinary course business circumstances, liquidity resources include the collateral directly deposited with EuroCCP, FX swap arrangements, and reverse repurchase agreements, as well as the use of the Facility. 15.  FAIR VALUE MEASUREMENT Fair value is the price that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities should include consideration of non-performance risk, including the Company’s own credit risk. The Company applied FASB ASC 820— Fair Value Measurement and Disclosure, which provides guidance for using fair value to measure assets and liabilities by defining fair value and establishing the framework for measuring fair value. ASC 820 applies to financial and nonfinancial instruments that are measured and reported on a fair value basis. The three-level hierarchy of fair value measurements is based on whether the inputs to those measurements are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The fair-value hierarchy requires the use of observable market data when available and consists of the following levels: ● Level 1—Unadjusted inputs based on quoted markets for identical assets or liabilities. ● Level 2—Observable inputs, either direct or indirect, not including Level 1, corroborated by market data or based upon quoted prices in non-active markets. ● Level 3—Unobservable inputs that reflect management’s best assumptions of what market participants would use in valuing the asset or liability. 108121 Table of Contents Company’s market assumptions. The fair value hierarchy requires the use of observable market data when available and consists of the following levels: ● Level 1—Unadjusted inputs based on quoted markets for identical assets or liabilities. ● Level 2—Observable inputs, either direct or indirect, not including Level 1 measurements, corroborated by market data or based upon quoted prices in non-active markets. ● Level 3—Unobservable inputs that reflect management’s best assumptions of what market participants would use in valuing the asset or liability.

The deferred compensation plan assets have an equal and offsetting deferred compensation plan liability based on the value of the deferred compensation plan assets. These securities are valued by obtaining feeds from a number of live data sources, including active market makers and inter-dealer brokers and therefore categorized as Level 1. No material adjustments were made to the carrying value of financial investments for the period ended December 31, 2021. See Note 1817 (“Employee Benefit Plan”Plans”) for more information. 122 Table of Contents Contingent Consideration LiabilityLiabilities In connection with the acquisitions of Hanweck, MATCHNow, and Chi-X Asia Pacific, as well as the acquisition of the assets of Silexx Financial Systems, LLC (“Silexx”),FT Options and Trade Alert, the Company acquired aentered into contingent consideration arrangementarrangements with the former owners of Silexx.owners.

The fair values areThat value is based on estimatesthe Company’s estimate of discounted future cash payments,the likelihood that certain performance targets in the respective acquisition agreements are expected to be accomplished. In connection with the contingent consideration arrangements, the Company paid a significant unobservable input,total of $9.1 million in contingent consideration to Hanweck, FT Options, Trade Alert and Chi-X Asia Pacific in 2021. Because the fair value measurements relating to the contingent consideration liabilities are considered asubject to management judgment, measurement uncertainty is inherent in the valuation of the contingent consideration liabilities as of the reporting date. Based on the recorded balance of the liabilities, any measurement uncertainty related to this Level 3 measurement.measurement is immaterial as of December 31, 2021. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain assets, such as goodwill and intangible assets, are measured at fair value on a non-recurring basis. For goodwill, the process involves using a market approach and income approach (using discounted estimated cash flows) to determine the fair value of each reporting unit on a stand-alone basis. That fair value is compared to the carrying amountvalue of the reporting unit, including its recorded goodwill. ImpairmentIn connection with the annual impairment evaluation of goodwill and indefinite life intangibles, impairment is considered to have occurred if the fair value of the 109 Table of Contents reporting unit is lower than the carrying amountvalue of the reporting unit. For the intangible assets, the process also involves using a discounted cash flow method to determine the fair value of each intangible asset. Impairment is considered to have occurred if the fair value of the intangible asset is lower than theits carrying amount.value. These measurements are considered Level 3 and these assets are recognized at fair value if they are deemed to be impaired. Equity investments without readily determinable fair values that are valued using the measurement alternative are measured at fair value on a non-recurring basis. See Note 6 (“Investments”) for more information. During the year ended December 31, 2019, a goodwill impairment charge of $10.5 million was recorded within2021, no observable transactions or impairments materially impacted the Corporate and Other segment.

In addition, property held for sale as of December 31, 2019 was also measured at fair value at December 31, 2019.

These petitions resulted in the establishment of 3 cases before the U.S. Tax Court. The Company also filed a complaint on October 5, 2018 with the Court of Federal Claims for a refund of Section 199 claims related to tax years 2008 through 2010. The complaint resulted in the establishment of a single case before the Court of Federal Claims. 133 Table of Contents The first case that went to trial involved certain subsidiaries related to electronic trading for tax years 2011, 2012 and 2013. The U.S. Tax Court held the trial remotely from May 24, 2021 to June 1, 2021. Post-trial briefing in that case concluded on October 28, 2021. On July 9, 2021, the Company believessought a stay in the second U.S. Tax Court case involving certain subsidiaries related to hybrid trading for the same tax years, which was denied on August 8, 2021. As a result, 2 cases remain pending in U.S. Tax Court, as does the case pending before the Court of Federal Claims. Trial dates in those cases have not been established. Although there can be no assurances, the Company continues to believe, based on its current assessment of the Section 199 claims, that the reasonably expected aggregate amount of any additional liabilities that may result from these examinations,cases, if any, will not have a material adverse effect on the financial position, results of operations, or cash flows of the Company. As of December 31, 2019, we have2021, the Company has not resolved these matters, and proceedings continue in U.S. Tax Court and the Court of Federal Claims. 23.  NET INCOME22.  EARNINGS PER COMMON SHARE The computation of basic net income per common share is calculated by reducing net income for the period by dividends paid or declared and undistributed net income for the period that are allocated to participating securities to arrive at net income allocated to common stockholders. Net income allocated to common stockholders is divided by the weighted average number of common shares outstanding during the period to determine net income per share allocated to common stockholders. The computation of diluted net income per share is calculated by dividing net income allocated to common stockholders by the sum of the weighted average number of common shares outstanding plus all additional common shares that would have been outstanding if the potentially dilutive common shares had been issued. The dilutive effect is calculated using the more dilutive of the two-class or treasury stock method. Additionally, the change in the redemption value for the noncontrolling interest reduces net income allocated to common stockholders. The following table sets forth the computation of basic and diluted earnings per share (in millions, except per share data): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31,  (in millions, except per share amounts) ​ 2019 ​ 2018 ​ 2017 Basic EPS Numerator:      ​           ​      ​ ​      Net Income ​ $ 370.8 ​ $ 425.2 ​ $ 400.6 Loss attributable to noncontrolling interest ​ ​ 4.1 ​ ​ 1.3 ​ ​ 1.1 Net Income excluding noncontrolling interest ​   374.9 ​   426.5 ​   401.7 Change in redemption value of noncontrolling interest ​ ​ (0.5) ​ ​ (1.3) ​ ​ (1.1) Earnings allocated to participating securities ​   (1.7) ​   (3.1) ​   (3.9) Net Income allocated to common stockholders ​ $ 372.7 ​ $ 422.1 ​ $ 396.7 Basic EPS Denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding ​ ​ 111.4 ​ ​ 111.8 ​ ​ 107.2 Basic Net Income Per Common Share ​ $ 3.35 ​ $ 3.78 ​ $ 3.70 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Diluted EPS Numerator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Net Income ​ $ 370.8 ​ $ 425.2 ​ $ 400.6 Loss attributable to noncontrolling interest ​ ​ 4.1 ​ ​ 1.3 ​ ​ 1.1 Net Income excluding noncontrolling interest ​   374.9 ​   426.5 ​   401.7 Change in redemption value of noncontrolling interest ​ ​ (0.5) ​ ​ (1.3) ​ ​ (1.1) Earnings allocated to participating securities ​   (1.7) ​   (3.1) ​   (3.9) Net Income allocated to common stockholders ​ $ 372.7 ​ $ 422.1 ​ $ 396.7 Diluted EPS Denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding ​ ​ 111.4 ​ ​ 111.8 ​ ​ 107.2 Dilutive common shares issued under stock program ​ ​ 0.4 ​ ​ 0.4 ​ ​ 0.3 Total dilutive weighted average shares ​ ​ 111.8 ​ ​ 112.2 ​ ​ 107.5 Diluted Net Income Per Common Share ​ $ 3.34 ​ $ 3.76 ​ $ 3.69 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31,  ​ ​ 2021 ​ 2020 ​ 2019 Basic earnings per share numerator:      ​           ​      ​ ​      Net income ​ $ 529.0 ​ $ 468.2 ​ $ 370.8 Net loss attributable to noncontrolling interest ​ ​ — ​ ​ — ​ ​ 4.1 Net income excluding redeemable noncontrolling interest ​   529.0 ​   468.2 ​   374.9 Change in redemption value of redeemable noncontrolling interest ​ ​ — ​ ​ — ​ ​ (0.5) Net income allocated to participating securities ​   (1.7) ​   (1.2) ​   (1.7) Net income allocated to common stockholders ​ $ 527.3 ​ $ 467.0 ​ $ 372.7 Basic earnings per share denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding ​ ​ 107.0 ​ ​ 109.1 ​ ​ 111.4 Basic earnings per share ​ $ 4.93 ​ $ 4.28 ​ $ 3.35 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Diluted earnings per share numerator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income ​ $ 529.0 ​ $ 468.2 ​ $ 370.8 Net loss attributable to redeemable noncontrolling interest ​ ​ — ​ ​ — ​ ​ 4.1 Net income excluding redeemable noncontrolling interest ​   529.0 ​   468.2 ​   374.9 Change in redemption value of redeemable noncontrolling interest ​ ​ — ​ ​ — ​ ​ (0.5) Net income allocated to participating securities ​   (1.7) ​   (1.2) ​   (1.7) Net income allocated to common stockholders ​ $ 527.3 ​ $ 467.0 ​ $ 372.7 Diluted earnings per share denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average shares outstanding ​ ​ 107.0 ​ ​ 109.1 ​ ​ 111.4 Dilutive common shares issued under stock program ​ ​ 0.2 ​ ​ 0.2 ​ ​ 0.4 Total dilutive weighted average shares ​ ​ 107.2 ​ ​ 109.3 ​ ​ 111.8 Diluted earnings per share ​ $ 4.92 ​ $ 4.27 ​ $ 3.34 ​ For the periods presented, the Company did not have shares of stock-based compensation that would have an anti-dilutive effect on the computation of diluted net incomeearnings per common share.share. 120134 Table of Contents 24.23. COMMITMENTS, CONTINGENCIES, AND GUARANTEES Legal Proceedings As of December 31, 2019,2021, the Company was subject to the various legal proceedings and claims discussed below, as well as certain other legal proceedings and claims that have not been fully resolved and that have arisen in the ordinary course of business. The Company reviews its legal proceedings and claims, regulatory reviews and inspections and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for those contingencies where the incurrence of a loss is probable and can be reasonably estimated, and the Company discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for ourthe consolidated financial statements to not be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable, but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company'sCompany’s assessment of whether a loss is remote, reasonably possible, or probable is based on its assessment of the ultimate outcome of the matter following all appeals. As of December 31, 2019,2021, the Company does not believe that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these legal proceedings and claims, regulatory reviews, inspections or other legal proceedings, if any, has been incurred. While the consequences of certain unresolved proceedings are not presently determinable, the outcome of any proceeding is inherently uncertain and an adverse outcome from certain matters could have a material effect on our earningsthe financial position, results of operations, or cash flows of the Company in any given reporting period. City of Providence On April 18, 2014, the City of Providence, Rhode Island filed a securities class action lawsuit in the Southern District of New York against Bats and Direct Edge Holdings LLC, as well as 14 other securities exchanges. The action purports to be brought on behalf of all public investors who purchased and/or sold shares of stock in the United States since April 18, 2009 on a registered public stock exchange (“Exchange Defendants”) or a U.S.-based alternate trading venue and were injured as a result of the alleged misconduct detailed in the complaint, which includes allegations that the Exchange Defendants committed fraud through a variety of business practices associated with, among other things, what is commonly referred to as high frequency trading. On May 2, 2014 and May 20, 2014, American European Insurance Company and Harel Insurance Co., Ltd. each filed substantially similar class action lawsuits against the Exchange Defendants which were ultimately consolidated with the City of Providence, Rhode Island securities class action lawsuit. On June 18, 2015, the Southern District of New York (the “Lower Court”) held oral argument on the pending Motion to Dismiss and thereafter, on August 26, 2015, the Lower Court issued an Opinion and Order granting Exchange Defendants’ Motion to Dismiss, dismissing the complaint in full. Plaintiff filed a Notice of Appeal of the dismissal on September 24, 2015 and its appeal brief on January 7, 2016. Respondent's brief was filed on April 7, 2016 and oral argument was held on August 24, 2016. Following oral argument, the Court of Appeals issued an order requesting that the SEC submit an amicus brief on whether the Lower Court had jurisdiction and whether the Exchange Defendants have immunity in the claims alleged. The SEC filed its amicus brief with the Court of Appeals on November 28, 2016 and Plaintiff and the Exchange Defendants filed their respective supplemental response briefs on December 12, 2016. On December 19, 2017, the Court of Appeals reversed the Lower Court’s dismissal and remanded the case back to the Lower Court. On March 13, 2018, the Court of Appeals denied the Exchange Defendants’ motion for re-hearing. The Exchange Defendants filed their opening brief for their motion to dismiss May 18, 2018, Plaintiffs’ response was filed June 15, 2018 and the Exchange Defendants’ reply was filed June 29, 2018. On May 28, 2019, the Lower Court issued an opinion and order denying the Exchange Defendants’ motion to dismiss. On June 17, 2019, the Exchange Defendants filed a motion seeking interlocutory appeal of the May 28, 2019 dismissal order, which was denied July 16, 2019. Exchange Defendants filed their answers on July 25, 2019. Given the preliminary natureTargeted discovery regarding class certification and legal preclusion concluded on April 26, 2021. On May 28, 2021, (1) Plaintiffs filed a Motion for Class Certification, (2) Bats and NYSE filed a joint Motion for Summary Judgment on Grounds of Legal Preclusion and a joint Motion for Summary Judgment on Grounds of Lack of Article III Standing, and (3) Nasdaq filed a Motion for Summary Judgment for Legal Preclusion. Briefing on these dispositive motions concluded in December 2021. The parties also filed motions to exclude some of the proceedings,other’s experts. Oral argument regarding the joint Motion for Lack of Article III Standing and Exchange Defendant’s motion to exclude the testimony of one of Plaintiffs’ experts is scheduled for March 11, 2022. The Company is unable to estimate what, if any, liability may result from this litigation. However, the Company believes that the claims are without merit and intends to litigate the matter vigorously. 121135 Table of Contents SIFMA Securities Industry Financial Markets Association (“SIFMA”) has filed a number of denial of access applications with the SEC to set aside proposed rule changes to establish or modify fees for Cboe Options, C2, BZX, BYX, EDGX and EDGA (the “Exchanges”) market data products and related services (the “Challenged Fees”). The Challenged Fees were held in abeyance pending a decision, which was issued by the SEC on October 16, 2018, on a separate SIFMA denial of access application regarding fees proposed by Nasdaq and the NYSE for their respective market data products. In a second order entered on October 16, 2018, the SEC issued an order (the “Order”) that remanded the stayed Challenged Fees and ordered the Exchanges to: (i) within six months of the Order, provide notice to the SEC of developed or identified fair procedures for assessing the Challenged Fees (the “Procedures”) and (ii) within one year of the Order, apply the Procedures to the Challenged Fees and submit to the SEC a record explaining the Exchanges’ conclusions. On October 26, 2018, the Exchanges filed a motion to reconsider the Order with the SEC. On November 21, 2018, the Exchanges filed with the SEC a joinder motion to NYSE’s prior motion for stay of the Order. On December 3, 2018, SIFMA filed a response to NYSE’s motion for stay. Nasdaq withdrew its motion to reconsider the Order with the SEC on December 4, 2018, and on December 5, 2018, filed a Petition for Review with the Court of Appeals for the D.C. Circuit (the “D.C. Circuit”). On December 14, 2018, the SEC denied the motion for stay but tolled the compliance date set forth in the remand order until ruling is made on the motion to reconsider. The Exchanges and NYSE filed on January 4, 2019 a motion to intervene in the Nasdaq Petition for Review to ensure the ability to participate in the case; the motion to intervene was granted on January 25, 2019. On the same day, SIFMA filed a motion with the D.C. Circuit moving to dismiss or hold in abeyance the Petition for Review. The Exchanges and NYSE submitted on February 6, 2019 a statement of issues for consideration in connection with the Petition for Review pending before the D.C. Circuit. On March 29, 2019, the D.C. Circuit issued an order indicating that SIFMA’s motion to dismiss will be considered with the underlying merits of the Petition for Review. On May 7, 2019, the SEC denied the Exchanges and NYSE’s motion for reconsideration of the Order. The SEC also further tolled the effectiveness of the remand order subject to the resolution of the substantive SIFMA case against Nasdaq and NYSE Arca that is already before the D.C. Circuit. On June 17, 2019, the Exchanges filed a petition for review of the May 7, 2019 SEC order denying reconsideration of the Order with the D.C. Circuit and of the Order. The Exchanges’ joint opening brief was filed on October 23, 2019. Oral arguments were held on February 18, 2020. An adverse ruling in that matter or a subsequent appeal could adversely affect exchange market data fees. However, the Company believes that the claims are without merit and intends to litigate the matter vigorously. The Company is unable to estimate what, if any, liability may result from this litigation. VIX Litigation On March 20, 2018, a putative class action complaint captioned Tomasulo v. Cboe Exchange, Inc., et al., No. 18-cv-02025 was filed in federal district court for the Northern District of Illinois alleging that the Company intentionally designed its products, operated its platforms, and formulated the method for calculating VIX and the Special Opening Quotation, (i.e., the special VIX value designed by the Company and calculated on the settlement date of VIX derivatives prior to the opening of trading), in a manner that could be collusively manipulated by a group of entities named as John Doe defendants. A number of similar putative class actions, some of which do not name the Company as a party, were filed in federal court in Illinois and New York on behalf of investors in certain volatility-related products. On June 14, 2018, the Judicial Panel on Multidistrict Litigation centralized the putative class actions in the federal district court for the Northern District of Illinois.

Plaintiffs request a judgment awarding class damages in an unspecified amount, as well as punitive or exemplary damages in an unspecified amount, prejudgment interest, costs including attorneys’ and experts’ fees and expenses and such other relief as the court may deem just and proper. On November 19, 2018, the Company filed a motion to dismiss the master consolidated complaint and the plaintiffs filed their response on January 7, 2019. The Company filed its reply on January 28, 2019. On May 29, 2019, the federal district court for the Northern District of Illinois granted the Company’s motion to dismiss plaintiffs’ entire complaint against the Company. The state law negligence claim was dismissed with prejudice and the other claims were dismissed without prejudice with leave to file an amended complaint, which plaintiffs filed on July 19, 2019. On August 28, 2019, the Company filed its second motion to dismiss the amended consolidated complaint and 122 Table of Contents plaintiffs filed their response on October 8, 2019.

In addition, while Cboe Europe, Limited and Cboe Chi-X Europe, EuroCCP, Cboe NL, Cboe Australia, Cboe Japan, and MATCHNow have not been the subject of any material litigation or regulatory investigation in the past, there is always the possibility of such action in the future. As both companiesCboe Europe and Cboe Chi-X Europe are domiciled in the U.K.,UK, it is likely that any action would be taken in the U.K.UK courts in relation to litigation or by the FCA in relation to any regulatory enforcement action. As EuroCCP is domiciled in the Netherlands, it is likely that any action would be taken in the Dutch courts in relation to litigation or by the DNB or Dutch Authority for Financial Markets in relation to any regulatory enforcement action.
