Uniti Group Inc. (the “Company”, “Uniti”, “we”, “us” or “our”) is an independent, internally managed real estate investment trust (“REIT”)REIT engaged in the acquisition, construction and leasing of mission critical infrastructure in the communications industry. We are principally focused on acquiring and constructing fiber optic, copper and coaxial broadband networks and data centers.

As of December 31, 2022,2023, Uniti and its subsidiaries own approximately 136,000140,000 fiber network route miles, representing approximately 8.08.5 million fiber strand miles, approximately 230,000231,000 route miles of copper cable lines, central office land and buildings across 44 states and beneficial rights to permits, pole agreements and easements. Refer to Part I, Item 2 “Properties” of this Annual Report on Form 10-K for a more detailed breakdown of our telecommunications properties.

Refer to Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Significant Business Developments,” of this Annual Report on Form 10-K for information regarding significant developments in our business in 2022.2023.

The current communications infrastructure industry is marked by the growing demand for and use of bandwidth-intensive devices and applications, such as smart devices, real-time and online streaming video, cloud-based applications, social media and mobile broadband. This growth in consumption requires the support of robust communications infrastructure, of which fiber networks and communications towers are critical components. Substantial investments have been made in recent years in fiber networks, lit services and colocation facilities to keep pace with the increased bandwidth use of both enterprise and consumer-end users. As companies attempt to keep pace with this rapidly evolving business sector, communications infrastructure continues to increase in priority and economic importance. We believe this considerable demand creates significant opportunities for us as an operator and as a funding source for operators seeking to capitalize on these trends through build outs and acquisitions of infrastructure assets.

The wireless communications industry is a prime example of the growing importance of the bandwidth infrastructure industry. As wireless traffic and mobile data consumption continue to grow worldwide, participants in the wireless communications industry are increasing their network capacity through the development of new wireless cell sites and the addition of bandwidth capacity. Consumers are demanding network quality and coverage, and as a result, wireless carriers are making significant capital investments to improve quality, expand their coverage and remain relevant in a highly competitive industry. We expect this continued growth in capital expenditures to generate high demands for bandwidth infrastructure services.

Our primary goal is to create long-term stockholder value by (i) generating reliable and growing cash flows, (ii) diversifying our tenant and asset base, (iii) paying a dividend and (iv) maintaining our financial strength and liquidity. To

We actively seek to acquirediversify our overall portfolio by acquiring communications infrastructure assets from communication service providers and leaseleasing these assets back to the communication service providers on a long-term basis. We believe

this type of transaction benefits the communication service providers with incremental liquidity which can be used to reduce indebtedness or for other investments, while they continue to focus on their existing business. We willseek to employ a disciplined, opportunistic acquisition strategy and seek to price transactions appropriately based on, among other things, growth opportunities, the mix of assets acquired, length and terms of the lease, and credit worthiness of the tenant.

Bandwidth intensive devices and applications are rapidly fueling worldwide consumption of bandwidth, which in turn fuels a continuously growing demand for stable and secure bandwidth options. Communications service providers and other enterprises whose services and businesses require substantial amounts of bandwidth are increasingly looking to infrastructure providers to support their bandwidth needs and to expand the reach, performance and security of their networks. We believe Uniti Fiber iswe are well positioned to capitalize on this ongoing demand for bandwidth infrastructure solutions.

We believe the communications infrastructure industry in the United States is currently going through an upgrade cycle driven by consumers’ general desire for greater bandwidth and wireless services. These upgrades require significant capital expenditures, and we believe Uniti provides a non-competitive funding source for communication service providers to help accelerate expansion of their networks.expenditures.

We intend to support our tenant operators and other communication service providers by providing capital topartnering with them for a variety of purposes, includingon infrastructure improvements such as capacity augmentation projects, tower construction and network expansions. We expect to structure these investments as lease arrangements that produce attractive returns for Uniti. For example, under the leases with our anchor tenant, Windstream, we have agreed to fund up to $1.75 billion in value accretive upgrades to the network we lease to Windstream in exchange for an 8% return and future rental rate increases. For more information on this program with Windstream, refer to Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of this Annual Report on Form 10-K.

The highly fragmented nature of the communication service sector is expected to result in more consolidation, which we believe will provide us ample opportunity to pursue these typesM&A transactions, including the acquisition or disposition of transactions.assets or businesses by Uniti or as a capital partner to potential acquirers in the communication service sector. For example, we may partner with operators through use of “OpCo-PropCo” structures, pursuant to which we acquire the underlying network and other assets and the operator acquires the operations.

We seek to maintain a capital structure that provides the resources and financial flexibility to position us to capitalize on strategic growth opportunities. Our access to, and cost of, external capital is dependent on various factors, including general market conditions, credit ratings on our securities, interest rates and expectations of our future business performance. We intend to maintain a strong balance sheet through disciplined use of leverage, aiming to lower our relative cost of capital over time, and continuing to have access to multiple sources of capital and liquidity. As of December 31,

We compete for investments in the communications industry with telecommunications companies, investment companies, private equity funds, hedge fund investors, sovereign funds and other REITs who focus primarily on specific segments of the communications infrastructure industry. The communications infrastructure industry is characterized by a high degree of competition among a large number of participants, including many local, regional and global corporations. Some of our competitors are significantly larger and have greater financial resources and lower costs of capital than we have. In addition, revenues from our network properties are dependent, to an extent, on the ability of our operating partners like Windstream, to compete with other communication service providers.

OurUniti's primary lines of business are Uniti Leasing and Uniti Fiber, which are described in further detail below.

Uniti Leasing is engaged in acquiring and constructing mission-critical communications assets, such as fiber, data centers, next-generation consumer broadband, coaxial and upgradeable copper, and leasing them back to anchor customers on

either an exclusive or shared-tenant basis. Presently, a substantial portion of Uniti Leasing’s revenue is rental revenues from leasing the Distribution Systems to Windstream as described below in the section titled “Significant Customers.” We believeWith Uniti Leasing, our attractive cost of capital and advantageous REIT structure will enable Uniti Leasinggoal is to provide creative and tax-efficient solutions to additional customers, including (i) sale leasebacksale-leaseback transactions, whereby Uniti Leasing acquires existing infrastructure assets from communications service providers and leases them back on a long-term basis; (ii) capital investment financing, whereby Uniti Leasing offers communications service providers a cost-efficient method of raising funds for discrete capital investments to upgrade or expand their network; and (iii) mergers and acquisitions financing, whereby Uniti Leasing facilitates mergers and acquisition transactions as a capital partner. Results for Uniti Leasing are reported in our consolidated financial statements in our Uniti Leasing business segment.

Uniti Fiber is a leading provider of infrastructure solutions, including cell site backhaul and small cell for wireless operators and ethernet, wavelengths and dark fiber for telecommunications carriers and enterprises. With Uniti Fiber, our goal is to capitalize on the rising demand by carriers and enterprises for dark fiber, establish ourselves as a proven small-cell systems provider and leverage wholesale enterprise opportunities as well as opportunities through the School and Libraries Program (commonly referred to as "E-Rate") administered by the Universal Service Administrative Company (also known as USAC). We believe fiber is the mission-critical focal point in the modern communications infrastructure industry and that Uniti Fiber will accelerate our growth and diversification strategy and expand our relationships with high quality national and international wireless carriers.

At December 31, 2022,2023, Uniti Fiber’s revenues under contract were over $1.1 billion, with a network consisting of approximately 2.93.0 million strand miles of fiber and approximately 28,13728,599 customer connections. Results for Uniti Fiber are reported in our consolidated financial statements in our Uniti Fiber Infrastructure business segment.

Uniti Group Inc. was incorporated in the state of Maryland on September 4, 2014.

Uniti operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally not subject to U.S. federal income taxes on income generated by its REIT operations. We have elected to treat the subsidiaries through which we operate our fiber business, Uniti Fiber, and certain aspects of our leasing business, Uniti Leasing, certain aspects of our former towers business, and our former small consumer competitive local exchange carrier business (the "Consumer CLEC Business" or “Talk America”), as taxable REIT subsidiaries (“TRSs”). TRSs enable us to engage in activities that result in income that does not constitute qualifying income for a REIT. Our TRSs are subject to U.S. federal, state and local corporate income taxes.

The Company operates through a customary up-REIT structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner. This structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership as a tax-efficient acquisition currency. As of December 31, 2022,2023, we are the sole general partner of the Operating Partnership and own approximately 99.96% of the partnership interests in the Operating Partnership. In addition, we have undertaken a series of transactions to permit us to hold certain of our assets indirectly through subsidiaries that are taxed as REITs, which may also facilitate future acquisition opportunities.

On December 31, 2022,2023, we employed 784813 people, of whom 460467 work directly developing and maintaining network operations, 110132 in sales and sales support, 68 in shared services, 7876 accounting and finance related positions and 6870 in operations support roles. None of our employees are subject to a collective bargaining agreement.

Our employees are our most important resources and their success ultimately creates our own. We fuel their success by offering career growth, recognition and appreciation programs, fulfilling work relationships, empowerment, mentoring, and training and development opportunities. We demonstrate the value we place in our employees financial, physical and emotional health by providing our employees with competitive salaries, health benefits, investment opportunities, vacation options and a generous paid volunteer program, among other benefits.

For the last foursix years Uniti has been certified as a Great Place to Work®. Our management team strives to embody and promote our company values of united, necessary, innovative, tenacious, and integrity. As a certified Great Place to Work®, 91%95% of our employees say they are treated fairly and are made to feel welcome. 80%89% of them agree that Uniti is a great place to work. We believe our energetic and collaborative work environment is a contributing factor to our limited employee turnover and high levels of engagement.

Within our organization, we believe in unity and know that it can only be generated through connection, collaboration and respect. We are committed to fostering these ideals by hiring, developing and supporting a diverse and inclusive workplace that encourages, supports and celebrates the diverse voices of our team members. Two women sit on our board of directors and women represent approximately 22%25% of leadership positions across our company. A key component to our commitment includes our Diversity and Inclusion Groups (“DIGs”) which support employees and allies in various experiences including diverse backgrounds, lifestyle, characteristics, and more. Uniti currently has fivesix active DIGs that allow for enrichment, connection and growth for our employees. Each DIG is sponsored and supported by senior leaders across the organization.

We value our strong ethical foundation and have instituted policies and procedures designed to preserve and prioritize corporate integrity. To actively promote honest, ethical and respectful conduct, we engage in a top-down approach by requiring our directors and executives to set high standards of integrity, responsibility, and transparency. We insist all employees adhere to a code of conduct that sets standards for appropriate behavior and includes information on preventing, identifying, reporting and stopping any type of discrimination or unethical behavior.

Uniti will continue to seek opportunities to support the overall health and well-being of our employees as we continue to realize significant value for our stockholders, customers and communities.

For the years ended December 31, 2023, 2022, and 2021, 67.3%, 66.5% and 2020, 66.5%, 66.4% and 65.8% of our revenues, respectively, were derived from leasing our Distribution Systems to Windstream.

On April 24, 2015, we were separated and spun-off from Windstream pursuant to which Windstream contributed the Distribution Systemscertain telecommunications network assets, including fiber and copper networks and other real estate (the "Distribution Systems") and the Consumer CLEC Business to Uniti and Uniti issued common stock and indebtedness and paid cash obtained from borrowings under Uniti’s senior credit facilities to Windstream. In connection with the Spin-Off, we entered into a long-term exclusive triple-net lease (the “Master Lease”) with Windstream, pursuant to which a substantial portion of our real property is leased to Windstream and from which a substantial portion of our leasing revenues are currently derived. In connection with Windstream’s emergence from bankruptcy, Uniti and Windstream bifurcated the Master Lease and entered into two structurally similar master leases (collectively, the “Windstream Leases”), which amended and restated the Master Lease in its entirety. The Windstream Leases consist of (a) a master lease (the "ILEC MLA") that governs Uniti owned assets used for Windstream’s incumbent local exchange carrier (“ILEC”) operations and (b) a master lease (the "CLEC MLA") that governs Uniti owned assets used for Windstream’s CLEC operations.

As of the date of this Annual Report on Form 10-K, Windstream is current on all lease payments. We note that in August 2020, Moody’s Investors Service assigned a B3 corporate family rating with a stable outlook to Windstream in connection with its post-emergence exit financing. At the same time, S&P Global Ratings assigned Windstream a B- issuer rating with a stable outlook. Both ratings remain current as of the date of this filing. In addition, in order to assist us in our continuing assessment of Windstream’s creditworthiness, we periodically receive certain confidential financial information and metrics from Windstream. Refer to Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of this Annual Report on Form 10-K for additional information regarding this assessment.

Our subsidiaries and our tenants operate in a regulated market. As operators of telecommunications facilities and services, both we and the current and future tenants of our telecommunications assets are typically subject to extensive and complex federal, state and local telecommunications laws and regulations. The Federal Communications Commission (“FCC”) regulates the provision of interstate and international telecommunications services, and state public utility commissions (“PUCs”) regulate intrastate telecommunications services. Federal and state telecommunications laws and regulations are wide-ranging, and violations of them can subject us and our tenants to civil, criminal and administrative sanctions. We expect that the telecommunications industry, in general, will continue to face increased regulation. Changes in laws and regulations and violations of federal or state laws or regulations by us or our tenants could have a significant direct or indirect effect on our operations and financial condition, as detailed below and set forth under “Risk Factors—Risks Related to Our Business.”

Our operations require that certain of our subsidiaries across all segments hold licenses or other forms of authorization from the FCC and state PUCs in those states where we operate, and in some jurisdictions our subsidiaries must file tariffs or other price lists describing their rates, terms and conditions of the services they provide. The FCC and PUCs can modify or terminate a service provider’s license or other authority to provide telecommunications services for failure to comply with applicable laws and regulations. The FCC and PUCs may also investigate our subsidiaries’ operations and may impose fines or other penalties for violations of the same. In addition, our subsidiaries are required to submit periodic reports to the FCC and PUCs documenting their revenues and other data. Some of this information is used as the basis for the imposition of various regulatory fees and other assessments. In order to engage in certain transactions in some jurisdictions, including changes of control, the encumbrance of certain assets, the issuance of securities, the incurrence of indebtedness, the guarantee of indebtedness of other entities, including subsidiaries of ours, and the transfer of assets, we may be required to provide notice and/or obtain prior approval from certain governmental agencies. Failure to obtain required approvals could subject us to fines or other penalties.

Our subsidiaries are subject to a number of federal, state, and local regulations that govern the way we can conduct our business. Such regulations may impose requirements and costs for our entities to operate and utilize local rights of way. They may also impose other operating costs on our businesses, including restrictions on pricing flexibility for certain products, minimum service quality standards, service reporting, intercarrier compensation, contributions to universal service, and other obligations. Further, the relaxation of regulatory requirements on our competitors, such as those granting us access to incumbent local exchange carrier facilities and/or services or the prices that such carriers may charge for such services or access to their facilities, may also have a detrimental effect on the businesses of our subsidiaries and/or tenants.

We have sought to structure the operations for our core real estate business in a manner to minimize the likelihood that we may be required to become regulated as a public utility or common carrier by the FCC or PUCs, but a number of our business operations are nonetheless subject to federal, state, and local regulation, and we cannot guarantee that our core real estate business will not become further subject to federal, state, and local regulation in the future.

neutrality” decision that declared broadband internet access services to be subject to certain “telecommunications services” regulation under Title II of the Communications Act of 1934. These regulations would have limited the ways that broadband internet access service providers could structure business arrangements and manage their networks and spurred additional restrictions, including rate regulation, which could adversely affect broadband investment and innovation. In 2017, the FCC voted to return broadband internet access service to its prior classification as “information services.” As a resultIn 2023 the FCC announced its intention to consider rules aimed at subjecting broadband internet service to regulation under Title II again. The regulatory classification of these decisions,broadband internet service is likely to continue to be subject to evolving standards set by the FCC. Further, state legislators and governors in some jurisdictions have introduced, and in some cases passed, state laws and executive orders requiring different levels of adherence to “network neutrality” principles for broadband internet access service providers active in the applicable states. As a result of thesethe FCC's activities, as well as state laws and regulations, it is unclear at this time how broadband internet services will be regulated in the future, and the potential impact those regulations may have on our broadband internet service business. In addition, while they have not sought to specifically regulate the manner in which broadband internet service providers manage network traffic, the FCC has nonetheless continued to adopt other forms of regulation over such services, such as broadband labelling requirements, which may affect our operations and subject us to sanctions if we fail to comply with them. We cannot anticipate what additional requirements may be imposed on our broadband internet access business by federal, state or local authorities in the future.

Our subsidiaries that compose Uniti Fiber own and operate significant fiber and other communications facilities throughout various regions of the United States. The provision of such services is often subject to FCC and PUC licensure in many jurisdictions, and the companies are typically licensed as CLECs and/or interexchange carriers in those states where they operate. The companies also hold various FCC wireless licenses in order to provide microwave backhaul and other wireless services. Because of the nature of the licenses that these companies hold, and the nature of the services that they provide, they are subject to various federal and state regulatory requirements, including, but not limited to, revenue and other reporting requirements and tariffing requirements. The companies must also maintain their wireless licenses with the FCC, which requires construction and notification reporting and other regulatory requirements. New fiber network construction is also subject to certain state and local governmental permitting and licensing requirements. Delays in the local and state permitting process can delay the construction of new facilities. Failure to abide by permit requirements can subject the company to fines and other penalties.

In some cases, our subsidiaries that compose Uniti Fiber utilize services or facilities of incumbent local exchange carriers through arrangements established under the Telecommunications Act of 1996 and FCC regulations. The FCC has recently issued orders allowing ILECs to stop offering such elements and/or to increase the rates that they may charge competitive providers for access to such elements. The loss of these elements, or significant price increases associated with our use of such elements, may increase our costs to maintain and construct new network facilities to replace those we may no longer access, or have other negative effects on our business such as a loss of ability to continue to provide services to certain customers.

A number of our subsidiaries that compose Uniti Fiber provide services to customers within the FCC’s E-Rate and Rural Healthcare (“RHC”) programs. E-Rate and RHC are a federally funded programs that provide discounts to assist eligible schools, libraries, and healthcare providers to fund the acquisition and operation of certain communications services and technology. These programs are administered by the Universal Service Administrative Company under the direction of the FCC. The E-Rate and RHC programs are subject to regulatory requirements that change often, and require strict-adherence to program requirements and deadlines. Failure to abide by program and regulatory requirements can result in loss of funding, claw back of prior funding, and fines or other sanctions. The E-Rate, RHC and other programs are funded by the universal service fund ("USF") programprogram. The USF program design, including the manner in which USF contributions are made by service providers, is currently subject to federal court challenges. They could also be modified by Congress or the FCC in the future. We cannot predict future developments or changes to the regulatory environment with respect to the USF, E-Rate or RHC programs, or the impact such developments or changes would have on our business.

Future revenues, costs, and capital investment in the communication businesses of our tenants, Uniti Fiber, and other related entities could be adversely affected by material changes to, or decisions regarding applicability of, government requirements, including, but not limited to, changes in rules governing inter-carrier compensation, interconnection access to network facilities, state and federal USF support, rules governing the prices that can be charged for business data services,

infrastructure location and siting rules, access to unbundled network elements, and other requirements. Federal and state

A wide variety of federal, state and local environmental and occupational health and safety laws and regulations affect telecommunications operations and facilities. These laws and regulations, and their enforcement, involve complex and varied requirements, and many such laws and regulations impose strict liability for violations. Some of these federal, state and local laws may directly impact us. Under various federal, state and local environmental laws, ordinances and regulations, an owner of real property, such as us, may be liable for the costs of removal or remediation of hazardous or toxic substances at, under or disposed of in connection with such property, as well as other potential costs relating to hazardous or toxic substances (including government fines and damages for injuries to persons and adjacent property). The cost of any required remediation, removal, fines or personal property damages and the owner’s liability therefore could exceed or impair the value of the property and/or the assets of the owner. In addition, the presence of such substances, or the failure to properly dispose of or remediate such substances, may adversely affect the owner’s ability to sell or rent such property or to borrow using such property as collateral, which, in turn, could reduce revenues.

We maintain, or will require in our leases (including the Windstream Leases) that our tenants maintain, applicable lines of insurance on our properties and their operations. Under the Windstream Leases, Windstream has the right to self-insure or use a captive provider with respect to its insurance obligations. We believe that the amount and scope of insurance coverage provided by our policies and the policies maintained by our tenants are customary for similarly situated companies in the telecommunications industry. However, our tenants may elect not to, or be able to, maintain the required insurance coverages, and the failure by any of them to do so could have a material adverse effect on us. We may not continue to require the same levels of insurance coverage under our leases, including the Windstream Leases, and such insurance may not be available at a reasonable cost in the future or fully cover all losses on our properties upon the occurrence of a catastrophic event. Moreover, we cannot guarantee the future financial viability of the insurers.

Our principal executive offices are located at 2101 Riverfront Drive, Suite A, Little Rock, AR 72202 and our telephone number is (501) 850-0820. We maintain a website at www.uniti.com. Our 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 or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act are available on our website, free of charge, as soon as reasonably practicable after we electronically file such materials with, or furnish them to, the Securities and Exchange Commission. Our Exchange Act filings can also be found at www.sec.gov.

Windstream is the lessee of the Distribution Systems pursuant to the Windstream Leases and, therefore, is presently the source of a substantial portion of our revenues. Thererevenues.There can be no assurance that Windstream will have sufficient assets, income and access to financing to enable it to satisfy its payment and other obligations under the Windstream Leases. In recent years, Windstream has experienced annual declines in its total revenue, sales and cash flow and has undergone a restructuring under Chapter 11 of the U.S. Bankruptcy Code.

The inability or unwillingness of Windstream to meet its rent obligations under the Windstream Leases could materially adversely affect our business, financial position or results of operations, including our ability to pay dividends to our stockholders as required to maintain our status as a REIT. The inability of Windstream to satisfy its other obligations under the Windstream Leases, such as the payment of insurance, taxes and utilities, could materially and adversely affect the condition of the Distribution Systems as well as the business, financial position and results of operations of Windstream. In addition, Windstream will be dependent on distributions from its subsidiaries in order to satisfy the payment obligations under the Windstream Leases, as such, if its subsidiaries were to experience a material and adverse effect on their business, financial position or results of operations, our business, financial position or results of operations could also be materially and adversely affected.

Failure by Windstream to comply with the terms of the Windstream Leases or to comply with the regulations to which the Distribution Systems are subject could require us to find another lessee for such Distribution Systems, or a portion thereof, and there could be a decrease or cessation of rental payments by Windstream.

There is no assurance that we would be able to lease the Distribution Systems to another lessee on substantially equivalent or better terms than the Windstream Leases, or at all, successfully reposition the Distribution Systems for other uses or sell the Distribution Systems on terms that are favorable to us. It may be more difficult to find a replacement tenant for a telecommunications property than it would be to find a replacement tenant for a general commercial property due to the specialized nature of the business. Even if we are able to find a suitable replacement tenant for the Distribution Systems, transfers of operations of communication distribution systems are subject to regulatory approvals not required for transfers of other types of commercial operations, which may affect our ability to successfully transition the Distribution Systems.

The initial term of the Windstream Leases expires on April 30, 2030. There can be no assurance that Windstream will renew the Windstream Leases upon their expiration.

If Windstream elects to renew the Windstream Leases, we and Windstream will need to reach a mutual agreement on the rent for the renewal term. The Windstream Leases require that the renewal rent be “Fair Market Rent,” and if we and Windstream are unable to agree on that amount, the renewal Fair Market Rent will be determined by an independent appraisal process. If the current rent payable by Windstream exceeds the Fair Market Rent at the time of renewal, then the renewal term rent will be lower than the current rent payable by Windstream. We are confident that any renewal will be at a rate reflecting fair value as required by the terms of the Windstream Leases and should be at an amount that will at least approximate current rent amounts, but we can provide no assurance as to the outcome of any negotiation or appraisal process. Any significant decrease in the renewal rent of the Windstream Leases could have a material adverse effect on our results of operations, financial condition and future prospects.

As of December 31, 2022,2023, we had outstanding long term indebtedness of approximately $5.26$5.62 billion consisting of senior notes and a revolving credit facility provided by a syndicate of banks and other financial institutions, which, as of December 31, 2022,2023, provided for an aggregate committed amount of borrowings up to approximately $500.0 million. Additionally, on February 23, 2024, we entered into the ABS Loan Agreement (as defined herein) which provides for the

ABS Loan Facility (as defined herein) of $350 million. See “Significant Business Developments” in Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Annual Report on Form 10-K for more information. Subject to the restrictions set forth in our debt agreements, our board of directors may establish and change our leverage

We intend to pursue acquisitions of additional properties and seek acquisitions and other strategic opportunities. Accordingly, we currently are, and expect in the future to be, engaged in evaluating potential transactions and other strategic alternatives. Although there is uncertainty that any of these discussions will result in definitive agreements or the completion of any transaction, we may devote a significant amount of our management resources to such a transaction, which could negatively impact our operations. We may incur significant costs in connection with seeking acquisitions or other strategic opportunities regardless of whether the transaction is completed. In the event that we consummate an acquisition or strategic alternative in the future, there is no assurance that we would fully realize the potential benefits of such a transaction. Integration may be difficult and unpredictable, and acquisition-related integration costs, including certain non-recurring charges, could materially and adversely affect our results of operations. Moreover, integrating assets and businesses may significantly burden management and internal resources, including the potential loss or unavailability of key personnel. If we fail to successfully integrate the assets and businesses we acquire, we may not fully realize the potential benefits we expect, and our operating results could be adversely affected.

Media outlets have recently reported, and may report in the future, that certain unaffiliated third parties are interested in acquiring us.us or that we may combine with another company. There can be no assurance that any such transaction will occur. We generally do not confirm or deny rumors, and we also do not generally announce negotiations or discussions

until definitive documentation has been executed. Such rumors and any related actions taken by third parties could adversely affect our business, as responding to such reports and activity can be costly and time-consuming, disruptive to our operations and divert the attention of management and our employees. Moreover, such reports and activities may create perceived uncertainties among current and potential customers, employees and other constituencies as to our future direction, which could result in the loss of business

As the owner, lessor and provider of communications services and distribution systems serving the communications industry, we are impacted by the risks associated with the communications industry. Therefore, our success is to some degree dependent on the communications industry, which could be adversely affected by economic conditions in general, changes in consumer trends and preferences, changes in communications technology designed to enhance the efficiency of communications distribution systems (including lit fiber networks and wireless equipment), and other factors over which we and our tenants have no control. As we are subject to risks inherent in substantial investments in a single industry, a decrease in the communications business or development and implementation of any such new technologies would likely have an adverse effect on our revenues.

The Windstream Leases require, and we expect that additional lease agreements that we enter into will require, that the tenant maintain comprehensive insurance and hazard insurance or self-insure its insurance obligations. However, there are certain types of losses, generally of a catastrophic nature, such as earthquakes, hurricanes and floods that may be uninsurable or not economically insurable. Insurance coverage may not be sufficient to pay the full current market value or current replacement cost of a loss. Inflation, changes in ordinances, environmental considerations, and other factors also might make it infeasible to use insurance proceeds to replace the property after such property has been damaged or destroyed. Under such circumstances, the insurance proceeds received might not be adequate to restore the economic position with respect to such property.

In addition, even if damage to our properties is covered by insurance, a disruption of business caused by a casualty event may result in loss of revenue for our tenants or us. Any business interruption insurance may not fully compensate them or us for such loss of revenue. If one of our tenants experiences such a loss, it may be unable to satisfy its payment obligations to us under its lease with us.

We rely on information technology networks and systems, including the internet, to process, transmit and store electronic information and to manage or support a variety of our business processes, including financial transactions and maintenance of records. We rely on commercially available systems, software, tools and monitoring to provide security for processing, transmitting and storing confidential information. Although we have taken steps to protect the security of the data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems’ improper functioning, or the improper disclosure of information in the event of cyber-attacks. Physical or electronic break-ins, computer viruses, attacks by hackers and similar security breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. Any failure to maintain proper function, security and availability of our information systems could interrupt our operations, damage our reputation, subject us to liability claims or regulatory penalties and could materially and adversely affect us.

Additionally, many of our employees may be working remotely from their homes, which could have the effect of exacerbating any of the foregoing risks. While we have taken steps to ensure the security of our data and to prevent security breaches, many of these measures are being deployed for the first time on a widespread and sustained basis, and there is no guarantee the data security and privacy safeguards we have put in place will be completely effective or that we will not encounter some of the common risks associated with employees accessing Company data and systems remotely. As a result, we may be required to expend significant capital and other resources to protect against security breaches or to alleviate problems caused by security breaches.

Uniti Fiber’sThe Company's business depends on providing customers with highly reliable service. The services provided are subject to failure resulting from numerous factors, including human error, power loss, improper maintenance, physical or electronic security breaches, fire, earthquake, hurricane, flood and other natural disasters, water damage, the effect of war, terrorism and any related conflicts or similar events worldwide, and sabotage and vandalism. Problems within Uniti Fiber’sour networks or facilities, whether within our control or the control of third-party providers, could result in service interruptions or equipment damage. We may not be able to efficiently upgrade or change Uniti Fiber’sour networks or facilities to meet new demands without incurring significant costs that we may not be able to pass on to customers. Given the service guarantees that may be included in Uniti Fiber’sthe Company's agreements with customers, such disruptions could result in customer credits; however, we cannot assume that customers will accept these credits as compensation in the future, and we may face additional liability or loss of customers.

We could be negatively impacted by unforeseen events, such as extreme weather events, natural disasters (including as a result of any potential effects of climate change), acts of vandalism or terrorism, or outbreak of highly infectious or contagious diseases. For example, the COVID-19 pandemic negatively impacted the global economy, disrupted global supply chains and created significant volatility and disruption of financial markets, and another pandemic or other

We operate as a REIT for U.S. federal income tax purposes, as does one of our principal operating subsidiaries. Our qualification as a REIT will depend on our satisfaction of certain highly technical and complex asset, income, organizational, distribution, stockholder ownership and other requirements, including at the level of our subsidiary REIT, on a continuing basis. Our ability to satisfy the asset tests depends upon our analysis of the characterization and fair market values of our assets, some of which are not susceptible to a precise determination and for which we may not obtain independent appraisals.

If we or our subsidiary REIT were to fail to qualify as a REIT in any taxable year, unless certain relief provisions apply, we would be subject to U.S. federal income tax on all of our taxable income at regular corporate rates and dividends paid to

our stockholders would not be deductible by us in computing our taxable income. As a result, we would no longer be required to pay dividends in order to qualify to be taxed as a REIT, and we could decide to reduce the amount of dividends we pay to our stockholders. Any resulting corporate liability could be substantial and could reduce the amount of cash available for distribution to our stockholders, which in turn could have an adverse impact on the value of our common stock and to service debt. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from re-electing to be taxed as a REIT for the four taxable years following the year in which we failed to qualify as a REIT.

The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Department of the Treasury (“Treasury”). Changes to the tax laws affecting REITs or TRSs, which may have retroactive application, could adversely affect our stockholders or us. We cannot predict how changes in the tax laws might affect our stockholders or us. Accordingly, we cannot provide assurance that new legislation, Treasury regulations, administrative interpretations or court decisions will not significantly affect our ability to remain qualified as a

Under applicable provisions of the Code, we will not be treated as a REIT unless we satisfy various requirements, including requirements relating to the sources of our gross income. Rents received or accrued by us from Windstream or other lessees will not be treated as qualifying rent for purposes of these requirements if the relevant lease is not respected as a “true lease” for U.S. federal income tax purposes and is instead treated as a service contract, joint venture or some other type of arrangement. If any of our leases, including the Windstream Leases, are not respected as a true lease for U.S. federal income tax purposes, we may fail to qualify as a REIT.

We generally must qualify as a REIT and distribute annually at least 90% of our REIT taxable income, determined without regard to the dividends paid deduction and excluding any net capital gains, for the U.S. federal corporate income tax not to apply to earnings that we distribute (assuming that certain other requirements are also satisfied). To the extent that we satisfy this distribution requirement and qualify for taxation as a REIT but distribute less than 100% of our REIT taxable income, determined without regard to the dividends paid deduction and including any net capital gains, we will be subject to U.S. federal corporate income tax on our undistributed net taxable income. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we distribute to our stockholders in a calendar year is less than a minimum amount specified for REITs under U.S. federal income tax laws. The same rules apply to our REIT subsidiary. We currently intend to make distributions to our stockholders, and to cause our REIT subsidiary to make distributions, to comply with the REIT requirements of the Code.

Our FFO is currently generated largely by rents paid under the Windstream Leases. From time to time, we may generate taxable income greater than our cash flow as a result of differences in timing between the recognition of taxable income and the actual receipt of cash or the effect of nondeductible capital expenditures, the creation of reserves or required debt or amortization payments. If we do not have other funds available in these situations, we could be required to borrow funds on unfavorable terms, sell assets at disadvantageous prices or distribute amounts that would otherwise be invested in future acquisitions in order to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT distribution requirement and to avoid corporate income tax and the 4% excise tax in a particular year. These alternatives could increase our costs or reduce our equity. Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our common stock and decrease cash available to service debt.

In addition to satisfying the distribution requirement described above in the immediately preceding risk factor, we and our subsidiary REIT must each satisfy a number of other requirements in order to qualify as a REIT. A deterioration in

Windstream’s financial condition could adversely affect our ability to satisfy several of these requirements and thus our ability to continue to qualify as a REIT.

For example, in order to qualify as a REIT for any year, at the end of each calendar quarter, at least 75% of the value of our assets must consist of cash, cash items, government securities and “real estate assets” (as defined in the Code), and no more than 20% of the value of our total assets can be represented by securities (other than qualified real estate assets) of one or more TRSs. If we fail to comply with either of these requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification. These same rules apply to our REIT subsidiary. Our ability to satisfy these requirements depends in substantial part on the value of the assets that are the subject of the Windstream Leases with Windstream, and any diminution in the value of such assets, including as a result of any diminution in the implied value of the Windstream Leases as a result of changes in the financial condition or creditworthiness of Windstream or Windstream’s inability or unwillingness to meet its rent and other obligations under the Windstream Leases, could adversely affect our ability to satisfy these requirements at the end of any calendar quarter, and there can be no assurance that we would be able to timely correct any such failure or otherwise qualify for any statutory relief provision. See “—Risks Related to Our Business—We are dependent on Windstream Holdings to make payments to us under the Windstream Leases, and an event that materially and adversely affects Windstream’s business, financial position or results of operations could materially and adversely affect our business, financial position or results of operations.” In addition, under applicable provisions of the Code, we

Even if we remain qualified for taxation as a REIT, we may be subject to certain U.S. federal, state and local taxes on our income and assets, including taxes on any undistributed income and state or local income, property and transfer taxes. For example, we hold some of our assets and conduct certain of our activities through a TRS that is subject to U.S. federal, state and local corporate-level income taxes as a regular C corporation. In addition, we may incur a 100% excise tax on transactions with a TRS if they are not conducted on an arm’s-length basis. Any of these taxes could decrease cash available for distribution to our stockholders and servicing our debt.

To qualify as a REIT for U.S. federal income tax purposes, we must ensure that, at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and “real estate assets” (as defined in the Code). The remainder of our investments (other than government securities, qualified real estate assets and securities issued by a TRS) generally cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value of our total assets (other than government securities, qualified real estate assets and securities issued by a TRS) can consist of the securities of any one issuer, no more than 20% of the value of our total assets can be represented by securities (other than qualified real estate assets) of one or more TRSs, and no more than 25% of the value of our total assets can be represented by nonqualified publicly offered REIT debt instruments (as defined in the Code). If we fail to comply with these requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. As a result of such asset limitations, we may be required to forego otherwise attractive investments. These actions could have the effect of reducing our income and amounts available for distribution to our stockholders and servicing our debt.

To qualify as a REIT, our annual dividend must not be less than 90% of our REIT taxable income on an annual basis, determined without regard to the dividends paid deduction and excluding any net capital gains. Our ability to pay dividends

may be adversely affected by a number of factors, including the risk factors herein. Dividends will be authorized by our board of directors and declared by us based upon a number of factors, including actual results of operations, restrictions under Maryland law or applicable debt covenants, our financial condition, our taxable income, the annual distribution requirements under the REIT provisions of the Code, our operating expenses and other factors our directors deem relevant. We cannot ensure that we will achieve investment results that will allow us to make a specified level of cash dividends or year-to-year increases in cash dividends in the future. Accordingly, because we are required to make distributions in certain amounts to our shareholders in order to maintain our REIT status and avoid incurring entity-level income and excise tax, we may elect to pay one or more dividends to our shareholders substantially in the form of additional shares of common stock. If we do so, the common stock that we distribute would be taxable dividend income to our shareholders, in whole or in part, based on the fair market value of our common stock at the time the dividend is paid.

Furthermore, while we are required to pay dividends in order to maintain our REIT status, (as described above under “Risks Related to the Status of Uniti as a REIT—REIT distribution requirements could adversely affect our ability to execute our business plan”), we may elect not to maintain our REIT status, in which case we would no longer be required to pay such dividends. Moreover, even if we do maintain our REIT status, after completing various procedural steps, we may elect to comply with the applicable distribution requirements by distributing, under certain circumstances, shares of our common stock in lieu of cash, which may result in holders of our common stock incurring tax liability without the receipt of a corresponding amount of cash. If we elect not to maintain our REIT status or to satisfy any required distributions in shares

We cannot predict the prices at which our common stock may trade. The market price of our common stock has fluctuated significantly since February 15, 2019 and may continue to fluctuate significantly, depending upon many factors, some of which may be beyond our control.

In order for us to qualify as a REIT, not more than 50% in value of our outstanding shares of stock may be owned, beneficially or constructively, by five or fewer individuals at any time during the last half of each taxable year after the first year for which we elect to be taxed and qualify as a REIT. Additionally, at least 100 persons must beneficially own our stock during at least 335 days of a taxable year (other than the first taxable year for which we elect to be taxed and qualify as a REIT). Our charter, with certain exceptions, authorizes our board of directors to take such actions as are necessary or advisable to preserve our qualification as a REIT. Our charter also provides that, unless exempted by the board of directors, no person may own more than 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of our common stock or more than 9.8% in value of the aggregate of the outstanding shares of all classes and series of our stock. The constructive ownership rules are complex and may cause shares of stock owned directly or constructively by a group of related individuals or entities to be constructively owned by one individual or entity. These ownership limits could delay or prevent a transaction or a change in control of us that might involve a premium price for shares of our stock or otherwise be in the best interests of our stockholders.

Our common stock is traded on the NASDAQ Global Select Market under the symbol “UNIT.”

Distributions with respect to our common stock are characterized for federal income tax purposes as taxable ordinary dividends, capital gains dividends, non-dividend distributions or a combination thereof. It has been our policy to declare dividends to common shareholders so as to comply with the provisions of the Internal Revenue Code governing REITs.

Any dividends must be declared by our Board of Directors, which will take into account various factors including our current and anticipated operating results, our financial position, REIT requirements, conditions prevailing in the market, restrictions in our debt documents and additional factors they deem appropriate. Dividend payments are not guaranteed and our Board of Directors may decide, in its absolute discretion, at any time and for any reason, not to pay dividends or to change the amount paid as dividends.

As a result, we may be required to record a provision in our Consolidated Financial Statements for U.S. federal income taxes related to the activities of the REIT and its pass-through subsidiaries for any undistributed income. We are subject to the statutory requirements of the locations in which we conduct business, and state and local income taxes are accrued as deemed required in the best judgment of management based on analysis and interpretation of respective tax laws.

The following management’s discussion and analysis of financial condition and results of operations describes the principal factors affecting the results of our operations, financial condition, and changes in financial condition, as well as our critical accounting estimates.

Uniti is an independent, internally managed REIT engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We are principally focused on acquiring and constructing fiber optic, copper and coaxial broadband networks and data centers.

Uniti operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally not subject to U.S. federal income taxes on income generated by its REIT operations, which includes income derived from the Windstream Leases. We have elected to treat the subsidiaries through which we operate our fiber business, Uniti Fiber, and certain aspects of our leasing business, Uniti Leasing, certain aspects of our former towers business, and our former Consumer CLEC Business, as TRSs.taxable REIT subsidiaries ("TRSs"). TRSs enable us to engage in

activities that result in income that does not constitute qualifying income for a REIT. Our TRSs are subject to U.S. federal, state and local corporate income taxes.

The Company operates through a customary up-REIT structure, pursuant to which we hold substantially all of our assets through the Operating Partnership that we control as general partner. This structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership as a tax-efficient acquisition currency. As of December 31, 2022,2023, we are the sole general partner of the Operating Partnership and own approximately 99.96% of the partnership interests in the Operating Partnership. In addition, we have undertaken a series of transactions to permit us to hold certain assets indirectly through subsidiaries that are taxed as REITs, which may also facilitate future acquisition opportunities.

We aim to grow and diversify our portfolio and tenant base by pursuing a range of transaction structures with communication service providers, including (i) sale-leaseback transactions, whereby we acquire existing infrastructure assets from third parties, including communication service providers, and lease them back on a long-term triple-net basis;

We manage our operations as the two reportable business segments, in addition to our corporate operations, which include:operations:

The following tablestable sets forth our results of operations expressed as dollars and as a percentage of total revenues for the periods indicated:

Because a substantial portion of our revenue and cash flows are derived from lease payments by Windstream pursuant to the Windstream Leases, there could be a material adverse impact on our consolidated results of operations, liquidity, financial condition and/or ability to maintain our status as a REIT and service debt if Windstream were to become unable to generate sufficient cash to make payments to us.

Under the terms of the Windstream Leases, Windstream is required to provide us audited financial statements as of and for the year ended December 31, 20222023 (the “2022“2023 Financial Statements”) no later than 90-days after its fiscal year-end. After receipt of the 20222023 Financial Statements, Uniti expects to file a Form 10-K/A to include the 20222023 Financial Statements in our annual report. As of the date of this Annual Report on Form 10-K, Windstream is current on all lease payments required under the Windstream Leases.

For the years ended December 31, 20222023 and 2021,2022, we recognized $301.4$297.1 million and $299.0$301.4 million of revenue, respectively, in our Uniti Fiber Infrastructure segment. The changedecrease in revenues of $4.3 million is primarily due to an increasea decrease in E-rate and government revenues of $8.5 million driven primarily by a decrease in equipment and installation sales, lit backhaul services revenues of $4.4 million driven primarily by decreased one-time unsplicing and cancellation fees and $3.6 million of dark fiber and small cells revenues of $18.9 millionrevenue related to one-time early termination and cancellation revenues, andpartially offset by an increase in enterpriseEnterprise and wholesale revenues of $8.1$12.0 million related todriven primarily by increased internet services and customer connections, partially offset by decreases of $8.5 million within enterprise and wholesale revenues driven by decreased equipment and installation sales, $7.9 million within lit backhaul services revenues due to the sale of our Uniti Fiber Northeast operations on May 28, 2021, and $8.8 million within E-Rate and government revenues related to decreased non-recurring construction projects.services.

General and administrative expenses include compensation costs, including stock-based compensation awards, professional and legal services, corporate office costs and other costs associated with the administrative activities of our segments.
