For information regarding CMS Energy’s and Consumers’ purpose and impact on the “triple bottom line” of people, planet, and profit, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.

Presented in the following illustration is Consumers’ 20212022 electric utility operating revenue of $5.0$5.4 billion by customer class:

Consumers’ electric utility operations are not dependent on a single customer, or even a few customers, and the loss of any one or even a few of Consumers’ largest customers is not reasonably likely to have a material adverse effect on Consumers’ financial condition.

In 2022, Consumers’ electric deliveries were 37 billion kWh, which included ROA deliveries of three billion kWh, resulting in net bundled sales of 34 billion kWh. In 2021, Consumers’ electric deliveries were 36 billion kWh, which included ROA deliveries of three billion kWh, resulting in net bundled sales of 33 billion kWh. In 2020, Consumers’ electric deliveries were 35 billion kWh, which included ROA deliveries of three billion kWh, resulting in net bundled sales of 32 billion kWh.

Consumers’ electric utility operations are seasonal. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment.

Presented in the following illustration are Consumers’ monthly weather-normalized electric deliveries (deliveries adjusted to reflect normal weather conditions) to its customers, including ROA deliveries, during 20212022 and 2020:2021:

Consumers’ 20212022 summer peak demand was 7,9518,061 MW, which included ROA demand of 581532 MW. For the 2020-20212021-2022 winter season, Consumers’ peak demand was 5,3865,559 MW, which included ROA demand of 465447 MW. As required by MISO reserve margin requirements, Consumers owns or controls, through long-term PPAs and short-term capacity purchases, all of the capacity required to supply its projected firm peak load and necessary reserve margin for summer 2022.2023.

Consumers is interconnected to the interstate high-voltage electric transmission system owned by METC and operated by MISO. Consumers is also interconnected to neighboring utilities and to other transmission systems.

In June 2022, Consumers received approval of its 2021 IRP, which updated its Clean Energy Plan. With these updates, Consumers expects to meet 90 percent of its customers’ needs with clean energy sources by 2040 through execution of its 2021 IRP,plan, which calls for replacing its coal-fueled generation predominantly with investment in renewable energy. CarbonNew technologies and carbon offset measures including, but not limited to, carbon sequestration, methane emission capture, and forest preservation, and reforestation may be used to close the gap to achieving net-zero carbon emissions. Specifically, the 2021 IRPClean Energy Plan provides for a full transition away from coal-fueled generation by the end of 2025 and includes the retirement of the D.E. Karn oil/gas-fueled and coal-fueled generating units in 2023 and the J.H. Campbell coal-fueled generating units in 2025. For further information on Consumers’ progress towards its net-zero carbon emissions goal, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.

Presented in the following table are details about Consumers’ 20212022 electric generation and supply mix:

Presented in the following table are the sources of Consumers’ electric supply for the last three years:

During 2021,2022, Consumers acquired 47 percent of the electricity it provided to customers through long-term PPAs and the MISO energy market. Consumers offers its generation into the MISO energy market on a day-ahead and real-time basis and bids for power in the market to serve the demand of its customers. Consumers is a net purchaser of power and supplements its generation capability with purchases from the MISO energy market to meet its customers’ needs during peak-demand periods.market.

At December 31, 2021,2022, Consumers had future commitments to purchase capacity and energy under long-term PPAs with various generating plants. These contracts require monthly capacity payments based on the plants’ availability or deliverability. The payments for 20222023 through 20482050 are estimated to total $8.0$8.5 billion and, for each of the next five years, range from $0.6$0.7 billion to $0.8 billion annually. These amounts may vary depending on plant availability and fuel costs. For further information about Consumers’ future capacity and energy purchase obligations, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Resources and Liquidity—Other Material Cash Requirements and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Contingencies and Commitments—Contractual Commitments.

During 2021, 322022, 29 percent of the energy Consumers provided to customers was generated by its coal-fueled generating units, which burned six million tons of coal and produced a combined total of 10,86110,217 GWh of electricity. In order to obtain the coal it needs, Consumers enters into physical coal supply contracts.

At December 31, 2021,2022, Consumers had future commitments to purchase coal through 2023;2024; payment obligations under these contracts totaled $116$104 million. Most of Consumers’ rail-supplied coal contracts have fixed prices, although some contain market-based pricing. Consumers’ vessel-supplied coal contracts have fixed base prices that are adjusted monthly to reflect changes to the fuel cost of vessel transportation. At December 31, 2021,2022, Consumers had 9585 percent of its 20222023 expected coal requirements under contract, as well as a 23-day34-day supply of coal on hand.

In conjunction with its coal supply contracts, Consumers leases a fleet of railcars and has transportation contracts with various companies to provide rail and vessel services for delivery of purchased coal to Consumers’ generating facilities. Consumers’ coal transportation contracts are future commitments and expire on various dates through 2025; payment obligations under these contracts totaled $533$428 million at December 31, 2021.2022.

During 2021, 162022, 19 percent of the energy Consumers provided to customers was generated by its natural gas‑fueled generating units, which burned 4049 bcf of natural gas and produced a combined total of 5,5556,684 GWh of electricity.

In order to obtain the gas it needs for electric generation fuel, Consumers’ electric utility purchases gas from the market near the time of consumption, at prices that allow it to compete in the electric wholesale market. For units 3 & 4 of D.E. Karn and for the Jackson and Zeeland plants, Consumers utilizes an agent that owns firm transportation rights to each plant to purchase gas from the market and transport the gas to the facilities. For units 3 & 4 of D.E. Karn, Consumers holds gas transportation contracts to transport to the plant gas that Consumers or an agent purchase from the market.

Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at ten percent of Consumers’ sales, with certain exceptions. At December 31, 2021,2022, electric deliveries under the ROA program were at the ten‑percent limit. Of Consumers’ 1.9 million electric customers, fewer than 300, or 0.02 percent, purchased electric generation service under the ROA program. For additional information, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties.

Consumers also faces competition or potential competition associated with industrial customers relocating all or a portion of their production capacity outside of Consumers’ service territory for economic reasons; municipalities owning or operating competing electric delivery systems; and customer self-generation. Consumers addresses this competition in various ways, including:

Presented in the following illustration is Consumers’ 20212022 gas utility operating revenue of $2.1$2.7 billion by customer class:

Consumers’ gas utility operations are not dependent on a single customer, or even a few customers, and the loss of any one or even a few of Consumers’ largest customers is not reasonably likely to have a material adverse effect on Consumers’ financial condition.

In 2022, deliveries of natural gas through Consumers’ pipeline and distribution network, including off-system transportation deliveries, totaled 391 bcf, which included GCC deliveries of 34 bcf. In 2021, deliveries of natural gas through Consumers’ pipeline and distribution network, including off-system transportation deliveries, totaled 347 bcf, which included GCC deliveries of 33 bcf. In 2020, deliveries of natural gas through Consumers’ pipeline and distribution network, including off-system transportation deliveries, totaled 360 bcf, which included GCC deliveries of 36 bcf. Consumers’ gas utility operations are seasonal. The consumption of natural gas typically increases in the winter, due primarily to colder temperatures and the resulting use of natural gas as heating fuel. Consumers injects natural gas into storage during the summer months for use during the winter months. During 2021, 462022, 48 percent of the natural gas supplied to all customers during the winter months was supplied from storage.

Presented in the following illustration are Consumers’ monthly weather-normalized natural gas deliveries (deliveries adjusted to reflect normal weather conditions) to its customers, including GCC deliveries, during 20212022 and 2020:2021:

In 2019, Consumers releasedUnder its Methane Reduction Plan, whichConsumers has set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers plans to reduce methane emissions from its system by about 80 percent by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will likely be offset by purchasing and/or producing renewable natural gas. For further information on Consumers’ progress towards its net-zero methane emissions goal, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.

Firm gas transportation or firm city-gate contracts are those that define a fixed amount, price, and delivery time frame. Consumers’ firm gas transportation contracts are with Panhandle Eastern Pipe Line Company and Trunkline Gas Company, LLC, each a non‑affiliated company. Under these contracts, Consumers purchases and transports gas to Michigan for ultimate delivery to its customers. Consumers’ firm gas transportation contracts expire on various dates through 2023 and provide for the delivery of 372024 with planned contract volumes providing 38 percent of Consumers’ total forecasted gas supply requirements in 2022.for 2023. Consumers purchases the balance of its required gas supply under firm city-gate contracts and through authorized suppliers under the GCC program.

CMS Energy’s enterprises segment,NorthStar Clean Energy, through various subsidiaries and certain equity investments, is engaged in domestic independent power production, including the development and operation of renewable generation, and the marketing of independent power production. The enterprises segment’sNorthStar Clean Energy’s operating revenue was $445 million in 2022, $308 million in 2021, and $229 million in 2020, and $248 million in 2019.

CMS Energy, Consumers, and their subsidiaries are subject to regulation by various federal, state, and local governmental agencies, including those described in the following sections. If CMS Energy or Consumers failed to comply with applicable laws and regulations, they could become subject to fines, penalties, or disallowed costs, or be required to implement additional compliance, cleanup, or remediation programs, the cost of which could be material. For more information on the potential impacts of government regulation affecting CMS Energy and Consumers, see Item 1A. Risk Factors, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook, and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 2, Regulatory Matters.

FERC has exercised limited jurisdiction over several independent power plants and exempt wholesale generators in which CMS EnterprisesNorthStar Clean Energy has ownership interests, as well as over CMS ERM, CMS Gas Transmission, and DIG. FERC’s jurisdiction includes, among other things, acquisitions, operations, disposals of certain assets and facilities, services provided and rates charged, and conduct among affiliates. FERC also has limited jurisdiction over holding company matters with respect to CMS Energy. FERC, in connection with NERC and with regional reliability organizations, also regulates generation and transmission owners and operators, load serving entities, purchase and sale entities, and others with regard to reliability of the bulk power system.

FERC regulates limited aspects of Consumers’ gas business, principally compliance with FERC capacity release rules, shipping rules, the prohibition against certain buy/sell transactions, and the price-reporting rule.

FERC also regulates certain aspects of Consumers’ electric operations, including compliance with FERC accounting rules, wholesale and transmission rates, operation of licensed hydroelectric generating plants, transfers of certain facilities, corporate mergers, and issuances of securities.

Consumers is subject to the jurisdiction of the MPSC, which regulates public utilities in Michigan with respect to retail utility rates, accounting, utility services, certain facilities, certain asset transfers, corporate mergers, and other matters.

The Michigan Attorney General, ABATE, the MPSC Staff, residential customer advocacy groups, environmental organizations, and certain other parties typically participate in MPSC proceedings concerning Consumers. These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief. The parties also have appealed significant MPSC orders.

The U.S. Secretary of Energy regulates imports and exports of natural gas and has delegated various aspects of this jurisdiction to FERC and the U.S. Department of Energy’s Office of Fossil Fuels.

The U.S. Department of Transportation’s Office of Pipeline Safety regulates the safety and security of gas pipelines through the Natural Gas Pipeline Safety Act of 1968 and subsequent laws.

The Transportation Security Administration, an agency of the U.S. Department of Homeland Security, regulates certain activities related to the safety and security of natural gas pipelines.

CMS Energy and Consumers are committed to protecting the environment; this commitment extends beyond compliance with applicable laws and regulations. In 2020, Consumers announced aConsumers’ Clean Energy Plan details its strategy to meet customers’ long-term energy needs and provides the foundation for its goal of achievingto achieve net-zero carbon emissions from its electric business by 2040. This goal includes not only emissions from Consumers’ owned generation, but also emissions from the generation of power purchased through long-term PPAs and from the MISO energy market.

Consumers expects to meet 90 percent of its customers’ needs with clean energy sources by 2040 through execution of its 2021 IRP,Clean Energy Plan, which calls for replacing its coal-fueled generation predominantly with investment in renewable energy. CarbonNew technologies and carbon offset measures including, but not limited to, carbon sequestration, methane emission capture, and forest preservation, and reforestation may be used to close the gap to achieving net-zero carbon emissions.

During 2021,In June 2022, Consumers provided 13 percentreceived approval of its electricity (self-generated2021 IRP, which updated its Clean Energy Plan. With these updates, Consumers will eliminate the use of coal-fueled generation in 2025 and purchased) from renewable sources. In February 2021, Consumers took ownership and began operation of a 166-MW wind generation project in Hillsdale, Michigan. Additionally, during 2021, Consumers entered into agreements to purchase two solar generating facilities as well as PPAs to purchaseforecasts renewable energy from solar generating facilities presently being developed by other parties.capacity levels of over 60 percent in 2040.

The safety of employees, customers, and the general public is a priority of CMS Energy and Consumers. Accordingly, CMS Energy and Consumers have worked to integrate a set of safety principles into their business operations and culture. These principles include complying with applicable safety, health, and security regulations and implementing programs and processes aimed at continually improving safety and security conditions. On an annual basis, CMS Energy and Consumers set various safety goals, with their primary measure being the OSHA recordable incident rate. The recordable incident rate was 1.17 in 2022 and 1.54 in 2021 and 1.22 in 2020.2021. The target recordable incident rate for 20222023 is 1.13. Since 2010,1.07. Over the last ten years, Consumers’ OSHA recordable incident rate has decreased by 4034 percent.

Within the utility industry, there is strong competition for rare, high-demand talent, including those related to renewable energy generation, technology, and data analytics. In order to address this competition and to be able to meet their human capital needs, CMS Energy and Consumers provide

This talent strategy allows CMS Energy and Consumers to shape employees’ experience and enable leaders to coach and develop co-workers, source talent, and anticipate and adjust to changing skill sets in the business environment.

As a part of their Talent Roadmap,People Strategy, CMS Energy and Consumers also employ a comprehensive diversity, equity, and inclusion strategy designed to embed diversity, equity, and inclusion into all aspects of their business. This is done through embedding standards for diversity, equity, and inclusion into all company processes and ensuring these standards are incorporated into all employee experiences. To measure their success, CMS Energy and Consumers utilize select questions in the annual engagement survey to create a diversity, equity, and inclusion index. For the year ended December 31, 2021,2022, the diversity, equity, and inclusion index score was 78 percent; 72 percent.

CMS Energy and Consumers have a goalare committed to achieve a scorebuilding an inclusive workplace that embraces the diverse makeup of 80 percent in 2022.the communities that they serve. The following table presents the composition of CMS Energy’s and Consumers’ workforce:

Presented in the following table are the company positions held during the last five years for each of CMS Energy’s and Consumers’ executive officers as of February 4, 2022:3, 2023:

CMS Energy’s internet address is www.cmsenergy.com. CMS Energy routinely posts important information on its website and considers the Investor Relations section, www.cmsenergy.com/investor-relations, a channel of distribution.distribution for material information. Information contained on CMS Energy’s website is not incorporated herein. CMS Energy’s and Consumers’ annual reports on Form 10‑K, quarterly reports on Form 10‑Q, current reports on Form 8-K, and any amendments to those reports filed pursuant to Section 13(a) or 15(d) of the Exchange Act are accessible free of charge on CMS Energy’s website. These reports are available soon after they are electronically filed with the SEC. Also on CMS Energy’s website are CMS Energy’s and Consumers’:

The SEC maintains an internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC. The address is www.sec.gov.

CMS Energy and Consumers are exposed to a variety of factors, often beyond their control, that are difficult to predict and that involve uncertainties that may materially adversely affect CMS Energy’s or Consumers’ business, liquidity, financial condition, or results of operations. Additional risks and uncertainties not presently known or that management believes to be immaterial may also adversely affect CMS Energy or Consumers. The risk factors described in the following sections, as well as the other information included in this report and in other documents filed with the SEC, should be considered carefully before making an investment in securities of CMS Energy or Consumers. Risk factors of Consumers are also risk factors of CMS Energy.

Due to its holding company structure, CMS Energy depends on dividends from its subsidiaries to meet its debt service and other payment obligations. If sufficient dividends were not paid to CMS Energy by its subsidiaries, CMS Energy might not be able to generate the funds necessary to fulfill its payment obligations.

Consumers’ ability to pay dividends or acquire its own stock from CMS Energy is limited by restrictions contained in Consumers’ preferred stock provisions and potentially by other legal restrictions, such as certain terms in its articles of incorporation and FERC requirements.

The level of CMS Energy’s present and future indebtedness could have several important effects on its future operations, including, among others, that:

CMS Energy’s ability to meet its debt service obligations and to reduce its total indebtedness will depend on its future performance, which will be subject to general economic conditions, industry cycles, changes in laws or regulatory decisions, and financial, business, and other factors affecting its operations, many of which are beyond its control. CMS Energy cannot make assurances that its businesses will continue to

CMS Energy and Consumers rely on the capital markets, as well as on bank syndications, to meet their financial commitments and short-term liquidity needs not otherwise funded internally.

Disruptions in the capital and credit markets, or the inability to obtain required FERC authorization for issuances of securities including debt, could adversely affect CMS Energy’s and Consumers’ access to liquidity needed for their businesses. Any liquidity disruption could require CMS Energy and Consumers to take measures to conserve cash including, but not limited to, deferring capital expenditures, changing commodity purchasing strategies to avoid collateral-posting requirements, and reducing or eliminating future share repurchases, dividend payments, or other discretionary uses of cash.

Entering into new financings is subject in part to capital market receptivity to utility industry securities in general and to CMS Energy’s and Consumers’ securities in particular. CMS Energy and Consumers continue to explore financing opportunities to supplement their respective financial strategies. These potential opportunities include refinancing and/or issuing new debt, issuing CMS Energy preferred stock and/or common equity, or entering into commercial paper, bank financing, and leasing arrangements. CMS Energy and Consumers cannot guarantee the capital markets’ acceptance of their securities. CMS Energy may also, from time to time, repurchase (either in open market transactions or through privately negotiated transactions), redeem, or otherwise retire its outstanding debt. Such activities, if any, will depend on prevailing market conditions, contractual restrictions, and other factors. The amounts involved may or may not be material.

Certain of CMS Energy’s and Consumers’ securities and those of their affiliates are rated by various credit rating agencies. A reduction or withdrawal of one or more of its credit ratings could have a material adverse impact on CMS Energy’s or Consumers’ ability to access capital on acceptable terms and maintain commodity lines of credit, could increase their cost of borrowing, and could cause CMS Energy or Consumers to reduce capital expenditures. If either or both were unable to maintain commodity lines of credit, CMS Energy or Consumers might have to post collateral or make prepayments to certain suppliers under existing contracts. Further, since Consumers provides dividends to CMS Energy, any adverse developments affecting Consumers that result in a lowering of its credit ratings could have an adverse effect on CMS Energy’s credit ratings.

The performance of various markets affects the value of assets that are held in trust to satisfy future obligations under CMS Energy’s and Consumers’ pension and postretirement benefit plans. CMS Energy and Consumers have significant obligations under these plans and hold significant assets in these trusts. These assets are subject to market fluctuations and will yield uncertain returns, which could fall below CMS Energy’s and Consumers’ forecasted return rates. A decline in the market value of the assets or a change in the level of interest rates used to measure the required minimum funding levels could significantly increase the funding requirements of these obligations. Also, changes in demographics, including an increased number of retirements or changes in life expectancy assumptions, could significantly increase the funding requirements of the obligations related to the pension and postretirement benefit plans.

Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at ten percent of Consumers’ sales, with certain exceptions. The proportion of Consumers’ electric deliveries under the ROA program and on the ROA waiting list is over ten percent. Consumers’ rates are regulated by the MPSC, while alternative electric suppliers charge market-based rates, putting competitive pressure on Consumers’ electric supply. If the ROA limit were increased or if electric generation service in Michigan were deregulated, it could have a material adverse effect on CMS Energy and Consumers.

Michigan law allows customers to use distributed energy resources for their electric energy needs. These distributed energy resources are connected to Consumers’ electric grid. The state distributed generation program is currently capped by the 2016 Energy Law at one percent of utilities’ peak loads, but in the settlement of its 2022 electric rate case, Consumers has voluntarily agreed to increase the cap to twofour percent on its system. Consumers is required to purchase distributed generation customers’ excess generation at rates determined by the MPSC. Recent FERC policy will also soon allow many customer-owned behind-the-meter and grid-connected distributed energy resources to participate in and receive revenue from wholesale electricity markets. Increased customer use of distributed energy resources could result in a reduction of Consumers’ electric sales. Third parties’ operations of distributed energy resources could also potentially have a negative impact on the stability of the grid. An increase in customers’ use of distributed energy resources, and the rate structure for distributed energy resources customers’ use of Consumers’ system and Consumers’ purchases of their excess generation, could have a material adverse effect on CMS Energy and Consumers.

CMS Energy and Consumers are subject to rate regulation. Consumers’ electric and gas retail rates are set by the MPSC and cannot be changed without regulatory authorization. If rate regulators fail to provide adequate rate relief, it could have a material adverse effect on Consumers or Consumers’ plans for making significant capital investments. Additionally, increasing rates could result in additional regulatory scrutiny, regulatory or legislative actions, and increased competitive or political pressures, all of which could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations.

Orders of the MPSC could limit recovery of costs of providing service. These orders could also result in adverse regulatory treatment of other matters. For example, MPSC orders could prevent or curtail Consumers from shutting off non‑paying customers or could prevent or limit the implementation of a gas revenue mechanism. Regulators could face competitive or political pressures to avoid or limit rate increases for a number of reasons, including economic downturn in the state or decreased customer base, among others.

The various risks associated with the MPSC and FERC regulation of CMS Energy’s and Consumers’ businesses, which include the risk of adverse decisions in any number of rate or regulatory proceedings before either agency, as well as judicial proceedings challenging any agency decisions, could have a material adverse effect on CMS Energy and Consumers. Changes to the tariffs or business practice manuals of certain wholesale market operators such as MISO, PJM, or ERCOT could also have a material adverse effect on CMS Energy and Consumers.

CMS Energy and Consumers are subject to, or affected by, extensive utility regulation and state and federal legislation. If it were determined that CMS Energy or Consumers failed to comply with applicable laws and regulations, they could become subject to fines, penalties, or disallowed costs, or be required to implement additional compliance, cleanup, or remediation programs, the cost of which could be material. CMS Energy and Consumers cannot predict the impact of new laws, rules, regulations, principles, or practices by federal or state agencies or wholesale electricity market operators, or challenges or changes to present laws, rules, regulations, principles, or practices and the interpretation of any adoption or change. Furthermore, any state or federal legislation concerning CMS Energy’s or Consumers’ operations could also have a material adverse effect.

FERC, through NERC and its delegated regional entities, oversees reliability of certain portions of the electric grid. CMS Energy and Consumers cannot predict the impact of FERC orders or actions of NERC and its regional entities on electric system reliability. Additionally, national gas pipeline infrastructure has recently been under scrutiny following disruptions related to extreme weather and cyber incidents. In 2021, the Transportation Security Administration issued two mandatory security directives related to natural gas pipelines that apply to Consumers. Additional regulation in this area could adversely affect Consumers’ gas operations.

Consumers has announced a long-term strategy for delivering clean, reliable, resilient, and affordable energy, including a plan to end coal use in 2025 as set forth in the 2021 IRP. The MPSC, FERC, other regulatory authorities, or other third parties may prohibit, delay, impair, or deny approval or consent ofimpair the 2021 IRP and some or all of the 2021 IRP-associated natural gas-fueled plant acquisitions of owned or deny reasonable rate recovery of the undepreciated plant balances associated with the retirement of coal-fueled plants necessary to proceed with the 2021 IRP.purchased electric generation capacity. Consumers may be unable to acquire, site, and/or permit some or all of the generation capacity proposed in the 2021 IRP. Consumers’ ability to implement the 2021 IRP may be affected by global supply chain disruptions and changes in the cost, availability, and supply of generation capacity. While CMS Energy and Consumers continue to advocate for advances in technologies required to reduce or eliminate greenhouse gases on a cost-effective basis, such advances are largely outside of CMS Energy’s and Consumers’ control. Advancements in technology related to items such as battery storage and electric vehicles may not become commercially available or economically feasible as projected in the 2021 IRP. Customer programs such as energy efficiency and demand response may not realize the projected levels of customer participation.

CMS Energy and Consumers could suffer financial loss, reputational damage, litigation, or other negative repercussions if they are unable to achieve their ambitious plan.plans.

CMS Energy and Consumers are required to make judgments regarding the potential tax effects of various financial transactions and results of operations in order to estimate their obligations to taxing

The Dodd-Frank Act provides for regulation by the Commodity Futures Trading Commission of certain commodity-related contracts. Although CMS Energy, Consumers, and certain subsidiaries of CMS EnterprisesNorthStar Clean Energy qualify for an end-user exception from mandatory clearing of commodity-related swaps, these regulations could affect the ability of these entities to participate in these markets and could add additional regulatory oversight over their contracting activities.

CMS Energy and Consumers are subject to costly and stringent environmental regulations that will likely require additional significant capital expenditures for CCR disposal and storage, cooling water intake equipment, effluent treatment, and PCB remediation. In addition, regulatory action on PFAS at the state and/or federal level could cause CMS Energy and Consumers to further test and remediate some sites if PFAS is present at certain levels. Present and reasonably anticipated state and federal environmental statutes and regulations will continue to have a material effect on CMS Energy and Consumers.

CMS Energy and Consumers have interests in fossil-fuel-fired power plants, other types of power plants, and natural gas systems that emit greenhouse gases. Federal, state, and statelocal environmental laws and rules, as well as international accords and treaties, could require CMS Energy and Consumers to install additional equipment for emission controls, undertake heat-rate improvement projects, purchase carbon emissions allowances, curtail operations, invest in generating capacity with fewer carbon dioxide emissions, or take other significant steps to manage or lower the emission of greenhouse gases. Similarly,

The following risks related to climate change, emissions, and environmental regulations could also have a material adverse impact on CMS Energy and Consumers:

Consumers expects to collect fully from its customers, through the ratemaking process, expenditures incurred to comply with environmental regulations, but cannot guarantee this outcome. If Consumers were unable to recover these expenditures from customers in rates, CMS Energy or Consumers could be required to seek significant additional financing to fund these expenditures.

For additional information regarding compliance with environmental regulations, see Item 1. Business—CMS Energy and Consumers Environmental Strategy and Compliance and Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook.

A delay or failure by CMS Energy or Consumers to obtain or maintain any necessary environmental permits or approvals to satisfy any applicable environmental regulatory requirements or install emission or pollution control equipment could:

Consumers expects to incur additional substantial costs related to the remediation of its former MGP sites and other response activity costs at a number of other sites, including, but not limited to, sites of retired coal-fueled electric generating units, under NREPA and CERCLA. Consumers believes these costs should be recoverable in rates, but cannot guarantee that outcome.

Consumers’ planned investments include the construction or acquisition of electric generation, electric and gas infrastructure, conversions and expansions, environmental controls, electric grid modernization

technology, and other electric and gas investments to upgrade delivery systems, as well as decommissioning of older facilities. The success of these capital investments depends on or could be affected by a variety of factors that include, but are not limited to:

It is possible that adverse events associated with these factors could have a material adverse effect on Consumers.

The agreements that CMS Energy and Consumers enter into for the sale of assets customarily include provisions whereby they are required to:

Many of these contingent liabilities can remain open for extended periods of time after the sales are closed. Depending on the extent to which the buyers might ultimately seek to enforce their rights under these contractual provisions, and the resolution of any disputes concerning them, there could be a material adverse effect on CMS Energy’s or Consumers’ liquidity, financial condition, and results of operations.

Consumers’ electric and gas utility businesses are affected by the economic conditions impacting the customers they serve. If the Michigan economy becomes sluggish or declines, Consumers could experience reduced demand for electricity or natural gas that could result in decreased earnings and cash flow. In addition, economic conditions in Consumers’ service territory affect its collections of accounts receivable and levels of lost or stolen gas.

Technology advances, government incentives and subsidies, and recent regulatory decisions could increase the cost effectiveness of customer-owned methods of producing electricity and managing energy use resulting in reduced load, cross subsidization, and increased costs.

Customers could also reduce their consumption through demand-side energy conservation and energy waste reduction programs.

CMS Energy’s and Consumers’ utility operations are seasonal. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment, while peak demand for natural gas typically occurs in the winter due to colder temperatures and the resulting use of natural gas as heating fuel. Accordingly, CMS Energy’s and Consumers’ overall results may fluctuate substantially on a seasonal basis. Mild temperatures during the summer cooling season and winter heating season as well as the impact of extreme weather events on Consumers’ system could have a material adverse effect.

In the regular course of business, CMS Energy and Consumers handle a range of sensitive confidential security and customer information. In addition, CMS Energy and Consumers operate in a highly regulated industry that requires the continued operation of sophisticated information and control technology systems and network infrastructure. Despite implementation of security measures, technology systems, including disaster recovery and backup systems, are vulnerable to failure, cyber crime, unauthorized access, and being disabled. These events could impact the reliability of electric generation and electric and gas delivery and also subject CMS Energy and Consumers to financial harm. Cyber crime, which includes the use of malware, computer viruses, and other means for disruption or unauthorized access against companies, including CMS Energy and Consumers, is increasing in frequency, scope, and potential impact. While CMS Energy and Consumers have not been subject to cyber incidents that have had a material impact on their operations to date, their security measures in place may be insufficient to prevent a major cyber incident in the future. If technology systems, including disaster recovery and backup systems, were to fail or be breached, CMS Energy and Consumers might not be able to fulfill critical business functions, and sensitive confidential and proprietary data could be compromised. In addition, because CMS Energy’s and Consumers’ generation, transmission, and distribution systems are part of an interconnected system, a disruption caused by a cyber incident at another utility, electric generator, system operator, or commodity supplier could also adversely affect CMS Energy or Consumers.

A variety of technological tools and systems, including both company-owned information technology and technological services provided by outside parties, support critical functions. The failure of these technologies, including backup systems, or the inability of CMS Energy and Consumers to have these technologies supported, updated, expanded, or integrated into other technologies, could hinder their business operations.

Consumers’ electric and gas delivery systems, power plants, gas infrastructure including storage facilities, wind energy or solar equipment, and energy products, and the independent power plants owned in whole or in part by CMS Energy could be involved in incidents, failures, or accidents that result in injury, loss of life, or property loss to customers, employees, or the public. Although CMS Energy and Consumers have insurance coverage for many potential incidents (subject to deductibles, limitations, and self-insurance amounts that could be material), depending upon the nature or severity of any incident, failure, or accident, CMS Energy or Consumers could suffer financial loss, reputational damage, and negative repercussions from regulatory agencies or other public authorities.

Natural disasters, severe weather, wars, terrorist acts, civil unrest, vandalism, theft, cyber incidents, pandemics, and other catastrophic events could result in severe damage to CMS Energy’s and Consumers’ assets beyond what could be recovered through insurance policies (which are subject to deductibles, limitations, and self-insurance amounts that could be material), could require CMS Energy and Consumers to incur significant upfront costs, and could severely disrupt operations, resulting in loss of service to customers. There is also a risk that regulators could, after the fact, conclude that Consumers’ preparedness or response to such an event was inadequate and take adverse actions as a result.

CMS Energy and Consumers are exposed to changes in market prices for commodities including, but not limited to, natural gas, coal, electric capacity, electric energy, emission allowances, gasoline, diesel fuel, and RECs. CMS Energy and Consumers manage commodity price risk using established policies and procedures, and they may use various contracts to manage this risk, including swaps, options, futures, and forward contracts. No assurance can be made that these strategies will be successful in managing CMS Energy’s and Consumers’ risk or that they will not result in net liabilities to CMS Energy or Consumers as a result of future volatility.

A substantial portion of Consumers’ operating expenses for its electric generating plants and vehicle fleet consists of the costs of obtaining these commodities. The contracts associated with Consumers’ fuel for electric generation and purchased power are executed in conjunction with the PSCR mechanism, which is designed to allow Consumers to recover prudently incurred costs associated with its positions in these commodities. If the MPSC determined that any of these contracts or related contracting policies were imprudent, recovery of these costs could be disallowed.

Natural gas prices in particular have been historically volatile. Consumers routinely enters into contracts for natural gas to mitigate exposure to the risks of demand, market effects of weather, and changes in commodity prices associated with the gas distribution business. These contracts are executed in conjunction with the GCR mechanism, which is designed to allow Consumers to recover prudently incurred costs associated with its natural gas positions. If the MPSC determined that any of these contracts or related contracting policies were imprudent, recovery of these costs could be disallowed.

CMS Energy and Consumers do not always hedge any or all of the exposure of their operations from commodity price volatility. Furthermore, the ability to hedge exposure to commodity price volatility depends on liquid commodity markets. As a result, to the extent the commodity markets are illiquid,

CMS Energy and Consumers might not be able to execute their risk management strategies, which could result in larger unhedged positions than preferred at a given time. To the extent that unhedged positions exist, fluctuating commodity prices could have a negative effect on CMS Energy and Consumers. Changes in laws that limit CMS Energy’s and Consumers’ ability to hedge could also have a negative effect on CMS Energy and Consumers.

Consumers has natural gas and coal supply and transportation contracts in place for the natural gas and coal it requires for its electric generating capacity. Consumers also has interstate transportation and

If Consumers were unable to obtain its supply requirements, it could be required to purchase natural gas or coal at higher prices, or implement its natural gas curtailment program filed with the MPSC.MPSC, or purchase replacement power at higher prices.

Unforeseen outages or maintenance of the electric and gas delivery systems, power plants, gas infrastructure including storage facilities and compression stations, wind energy or solar equipment, and energy products owned in whole or in part by CMS Energy or Consumers may be required for many reasons. When unplanned outages occur, CMS Energy and Consumers will not only incur unexpected maintenance expenses, but may also have to make spot market purchases of electric and gas commodities that may exceed CMS Energy’s or Consumers’ expected cost of generation or gas supply, be forced to curtail services, or retire a given asset if the cost or timing of the maintenance is not reasonable and prudent. Unplanned generator outages could reduce the capacity credit CMS Energy or Consumers receives from MISO and could cause CMS Energy or Consumers to incur additional capacity costs in future years.

Adverse economic conditions or financial difficulties experienced by counterparties with whom CMS Energy and Consumers do business could impair the ability of these counterparties to pay for

CMS Energy’s and Consumers’ services and/or fulfill their contractual obligations, including performance and payment of damages. CMS Energy and Consumers depend on these counterparties to remit payments and perform contracted services in a timely and adequate fashion. Any delay or default in payment or performance, including inadequate performance, of contractual obligations could have a material adverse effect on CMS Energy and Consumers.

Volatility and disruptions in capital and credit markets could have a negative impact on CMS Energy’s and Consumers’ lenders, vendors, contractors, suppliers, customers, and other counterparties, causing them to fail to meet their obligations.

CMS Energy and Consumers could suffer negative impacts to their reputations as a result of operational incidents, violations of corporate policies, regulatory violations, inappropriate use of social media, or other events. Reputational damage could have a material adverse effect and could result in negative customer perception and increased regulatory oversight.

UnionsAt December 31, 2022, unions represent 42 percent of Consumers’ employees. Consumers’ union agreements expire in 2025. If these employees were to engage in a strike, work stoppage, or other slowdown, Consumers could experience a significant disruption in its operations and higher ongoing labor costs.

In some areas, competition for skilled employees is high and if CMS Energy and Consumers were unable to match skill sets to future needs, they could encounter operating challenges and increased costs. These challenges could include a lack of resources, loss of knowledge, and delays in skill development. Additionally, higher costs could result from the use of contractors to replace employees, loss of productivity, and safety incidents. Failing to train replacement employees adequately and to transfer internal knowledge and expertise could adversely affect CMS Energy’s and Consumers’ ability to manage and operate their businesses.
