PART I

Overview

We own, operate and lease shared communications infrastructure that is geographically dispersed throughout the U.S., including (1) more than 40,000 towers and other structures, such as rooftops (collectively, "towers"), (2) approximately 105,000 small cell nodes either currently generating revenue or under contract and (3) approximately 90,000 route miles of fiber primarily supporting small cells and fiber solutions. We refer to our towers, small cells and fiber assets collectively as "communications infrastructure," and, at times, to our customers on our communications infrastructure as "tenants." Our operating segments historically consisted of (1) Towers and (2) Fiber, which includes both small cells and fiber solutions.

On March 13, 2025, management signed a definitive agreement ("Strategic Fiber Agreement") to sell our Fiber segment, together with certain supporting assets and personnel ("Fiber Business"), with Zayo Group Holdings Inc. ("Zayo") acquiring the fiber solutions business and EQT Active Core Infrastructure fund ("EQT") acquiring the small cell business ("Strategic Fiber Transaction"). Under the agreement, we will receive $8.5 billion in aggregate, subject to certain closing adjustments. The Strategic Fiber Transaction is expected to close in the first half of 2026, subject to certain closing conditions and regulatory approvals.

As the aforementioned sale represents a material strategic shift for the Company, the Fiber Business' results and net assets are presented herein as discontinued operations and comparable prior periods have been recast to reflect this change. Pending the closing of the Strategic Fiber Transaction, we will continue to operate the Fiber Business in accordance with the Strategic Fiber Agreement. Following the classification of the Fiber Business as discontinued operations, the Company has one reportable segment, which is also its operating segment, that constitutes consolidated results consisting of its towers operations. Unless otherwise noted, all activities and amounts reported in this document relate to the continuing operations of the Company and exclude activities and amounts related to the Fiber Business.

Our core business is providing access, including space or capacity, to our towers via long-term contracts in various forms, including lease, license, sublease and service agreements (collectively, "tenant contracts"). We seek to increase our site rental revenues by adding more tenants on our towers, which we expect to result in significant incremental cash flows due to our low incremental operating costs. We operate as a REIT for U.S. federal income tax purposes. See "Item 1. Business—REIT Status" and notes 2 and 10 to our consolidated financial statements.

Approximately 56% and 71% of our towers are located in the 50 and 100 largest U.S. basic trading areas ("BTAs"), respectively. Our towers have a significant presence in each of the top 100 BTAs. We derive approximately 40% of our towers Adjusted Site Rental Gross Margin from towers located on land that we own, including through fee interests and perpetual easements, and we derive approximately 60% of our towers Adjusted Site Rental Gross Margin from towers located on land that we lease, sublease, manage or license. The contracts for the land under our towers have an average total remaining life of approximately 35 years (including all renewal terms exercisable at our option), weighted based on towers Adjusted Site Rental Gross Margin.

Our largest tenants are T-Mobile, AT&T and Verizon Wireless, which collectively accounted for approximately 90% of our 2025 site rental revenues. See note 15 to our consolidated financial statements for further information regarding our largest tenants. Site rental revenues represented 95% of our 2025 net revenues. The vast majority of our site rental revenues are of a recurring nature and are derived from long-term tenant contracts. See "Item 1. Business—The Company" for further information. As of December 31, 2025, exclusive of renewals exercisable at the tenants' option, our tenant contracts had a weighted-average remaining life of approximately six years and represented $23.7 billion of expected future cash inflows, exclusive of amounts owed from DISH Wireless L.L.C. ("DISH"). See note 18 to our consolidated financial statements for a discussion of the notice of default and termination delivered to DISH.

As part of our effort to provide comprehensive tower solutions, as an ancillary business, we also offer certain services relating to our towers predominately consisting of pre-construction site development services relating to existing or new tenant equipment installations, including: site acquisition, architectural and engineering, or zoning and permitting (collectively, "site development services").

See note 17 to our consolidated financial statements for a discussion of the July 2023 restructuring ("2023 Restructuring Plan"), which included discontinuing tenant equipment installations and subsequent augmentations (collectively, "installation services") as a towers product offering and (2) the June 2024 restructuring plan ("2024 Restructuring Plan," and together with the 2023 Restructuring Plan, "2023 and 2024 Restructuring Plans"). In February 2026, we initiated a restructuring plan ("2026 Restructuring Plan") as part of our efforts to enhance the efficiency and effectiveness of our tower business. See note 18 to our consolidated financial statements for a discussion of the 2026 Restructuring Plan.

Strategy

As a leading provider of towers in the U.S., our strategy is to create long-term stockholder value via a combination of (1) growing cash flows generated from our existing portfolio of towers, (2) returning a meaningful portion of our cash generated by operating activities to our common stockholders in the form of dividends and (3) investing capital efficiently to grow cash flows and long-term dividends per share. Our strategy is based, in part, on our belief that the U.S. is the most attractive market for tower investment with the greatest long-term growth potential. We measure our efforts to create "long-term stockholder value" by the combined payment of dividends to stockholders and growth in our per-share results. The key elements of our strategy are to:

*•*Grow cash flows from our existing towers. We are focused on maximizing the recurring site rental cash flows generated from providing our tenants with long-term access to our towers, which we believe is the core driver of value for our stockholders. Tenant additions or modifications of existing tenant equipment (collectively, "tenant additions") enable our tenants to expand coverage and capacity in order to meet increasing demand for data while generating high incremental returns for our business. We believe our towers provide an efficient and cost-effective solution for our wireless tenants' growing networks that provides an opportunity to generate cash flows and increase stockholder return.

• Return cash generated by operating activities to stockholders in the form of dividends and share repurchases. We believe that distributing a meaningful portion of our cash generated by operating activities appropriately provides stockholders with increased certainty for a portion of expected long-term stockholder value while still allowing us to retain sufficient flexibility to invest in our business and deliver growth. We believe this decision reflects the translation of the high-quality, long-term contractual cash flows of our business into stable capital returns to stockholders.

• Invest capital efficiently to grow cash flows and long-term dividends per share. In addition to adding tenants to existing towers, we seek to invest our available capital, including the net cash generated by our operating activities and external financing sources, in a manner that will increase long-term stockholder value on a risk-adjusted basis. These investments include constructing and acquiring new towers that we expect will generate future cash flow growth and attractive long-term returns by adding tenants to those assets over time. Our historical investments have included the following (in no particular order):

◦acquisitions of land interests (which primarily relate to land assets under towers);

◦construction of towers;

◦acquisitions of towers;

◦improvements and structural enhancements to our existing towers;

◦purchases of shares of our common stock from time to time; and

◦purchases, repayments or redemptions of our debt.

Our strategy to create long-term stockholder value is based on our belief that there will be considerable future demand for our towers based on the location of our assets and the rapid and continuing growth in the demand for data. We believe that such demand for our towers will continue, will result in growth of our cash flows due to tenant additions on our existing towers, and will create other growth opportunities for us, such as demand for newly constructed or acquired towers, as described above. Further, we seek to augment the long-term value creation associated with growing our recurring site rental cash flows by offering certain ancillary site development services.

REIT Status

We operate as a REIT for U.S. federal income tax purposes. As a REIT, we are generally entitled to a deduction for dividends that we pay and, therefore, are not subject to U.S. federal corporate income tax on our net taxable income that is currently distributed to our stockholders. We may be subject to certain federal, state, local and foreign taxes on our income or assets, including (1) taxes on any undistributed income, (2) taxes related to our taxable REIT subsidiaries ("TRSs"), (3) franchise taxes, (4) property taxes and (5) transfer taxes. In addition, we could, under certain circumstances, be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Internal Revenue Code of 1986, as amended ("Code"), to maintain qualification for taxation as a REIT. Qualified REIT dividends (within the meaning of Section 199A(e)(3) of the Code) constitute a part of a non-corporate taxpayer's "qualified business income amount" and thus our non-corporate U.S. stockholders may be eligible to take a qualified business income deduction in an amount equal to 20% of such dividends received from us. This deduction was made permanent with Public Law 119-21, commonly referred to as the "One Big Beautiful Bill Act", being signed into law in the U.S. on July 4, 2025.

The vast majority of our assets and revenues are in the REIT. See notes 2 and 10 to our consolidated financial statements. Additionally, we have included in TRSs certain other assets and operations. Those TRS assets and operations will continue to be subject, as applicable, to federal and state corporate income taxes or to foreign taxes in the jurisdictions in which such assets and operations are located.

Our foreign assets and operations (primarily our tower operations in Puerto Rico) most likely will be subject to foreign income taxes in the jurisdictions in which such assets and operations are located, regardless of whether or not they are included in a TRS.

To remain qualified and be taxed as a REIT, we are generally required to annually distribute to our stockholders at least 90% of our REIT taxable income, after the utilization of our net operating loss carryforwards "NOLs" (determined without regard to the dividends paid deduction and excluding net capital gain). See notes 2 and 10 to our consolidated financial statements. Our quarterly common stock dividend will delay the utilization of our NOLs and may cause certain of the NOLs to expire without utilization. See "Item 1A. Risk Factors" for risks associated with our REIT status.

Industry Overview

Consumer demand for data continues to grow due to increases in data consumption and increased penetration of bandwidth-intensive devices. This increase in data consumption is driven by factors such as growth in (1) mobile entertainment (such as mobile video, mobile applications and social networking), (2) mobile internet usage (supporting web browsing and trends in telehealth, remote working, online learning and other remote communications), (3) machine-to-machine applications or the "Internet of Things" (such as connected cars and wearables), and (4) the adoption of other bandwidth-intensive applications (such as cloud services, artificial intelligence and video communications). As a result, consumer wireless devices are trending toward bandwidth-intensive devices, including smartphones, laptops, tablets and other emerging and embedded devices, and U.S. wireless carriers are among the first carriers in the world to offer commercial 5th Generation ("5G") mobile cellular communications services to further support such growth.

We expect the following factors to contribute to potential demand for our towers:

• consumers' growing wireless data consumption leading major wireless carriers to upgrade and enhance their networks through the efficient use of towers, including in connection with 5G deployments, in an effort to improve network quality and capacity and customer retention or satisfaction;

• prior and future potential spectrum auctioned, licensed or made available by the Federal Communications Commission ("FCC") enabling additional wireless carrier network development;

• next-generation technologies and new uses for wireless communications may potentially result in new entrants or increased demand in the wireless industry, which may include companies involved in the continued evolution and deployment of the Internet of Things;

• the continued adoption of bandwidth-intensive applications, including artificial intelligence; and

• increased government initiatives to expand broadband infrastructure to support connectivity throughout the U.S.

The Company

Virtually all of our towers operations are located in the U.S. Following the classification of the Fiber Business as discontinued operations, the Company has one reportable segment, which is also its single operating segment, that constitutes consolidated results consisting of its towers operations. For more information, see "Item 7. MD&A—Results of Operations" and note 15 to our consolidated financial statements. Our core business is providing access, including space or capacity, to our towers via long-term tenant contracts in the U.S. We believe our towers are integral to our tenants' networks and organizations. See "Item 1. Business—Strategy."

We believe towers are the most efficient and cost-effective solution for providing coverage and capacity for wireless carrier network deployments. We acquired ownership interests or exclusive rights to the majority of our towers directly or indirectly from the largest U.S. wireless carriers (or their predecessors) through transactions consummated since 1999, including towers from (1) AT&T in 2013, (2) T-Mobile in 2012, (3) companies now part of T-Mobile in 2007, (4) companies now part of Verizon Wireless in 1999 and 2000 and (5) companies now part of AT&T in 1999 and 2000.

We generally receive monthly rental payments and, in some cases, upfront payments, from our tenants pursuant to long-term tenant contracts with (1) initial contract terms generally between five to 15 years, (2) multiple renewal periods of generally five years each, exercisable at the option of the tenant, (3) limited termination rights for our tenants and (4) contractual escalations of the rental price. We strive to negotiate with our existing tenant base for longer contractual terms, which often contain fixed escalation rates.

Our tenant contracts, while amended and re-negotiated over time, have historically led to a long-term relationship with tenants on our towers, resulting in a retention rate generally between 98% and 99% each year. In general, each renewable tenant contract automatically renews at the end of its term unless (1) the tenant provides prior notice of its intent not to renew or (2) the contract is amended or re-negotiated. See "Item 1A. Risk Factors" for additional information regarding higher non-renewals (which we define as the reduction in site rental revenues as a result of tenant churn, terminations and, in limited circumstances, reductions of existing lease rates) incurred as a result of the T-Mobile and Sprint network consolidation as well as in relation to the notice of default and termination delivered to DISH. See notes 4 and 18 to our consolidated financial statements for a tabular presentation of the minimum rental payments due to us by tenants pursuant to tenant contracts without consideration of tenant renewal options as of December 31, 2025 and discussion of the DISH default and termination, respectively.

The average monthly rental payment from a new tenant added to towers can vary based on (1) aggregate tenant volume, (2) the location of the tower, or (3) the amount of tower and ground space leased to a tenant, which can be influenced by the quantity, size, and weight of the tenant's antenna installation or related equipment. When possible, we seek to receive rental payment increases in connection with tenant contract amendments, pursuant to which our tenants add antennas or other equipment to our towers or ground space on which they already have equipment pursuant to preexisting tenant contracts. Our tenant contracts and pricing are not influenced by whether or not we perform the site development services.

As of December 31, 2025, the average number of tenants (calculated as a unique license together with any related amendments thereto) per tower was approximately 2.4.

Additional Site Rental Information. We have existing master agreements with our largest tenants, including T-Mobile, AT&T and Verizon Wireless. Such agreements provide certain terms (including economic terms) that govern underlying contracts (entered into during the term of the master agreements) regarding the right to use our towers by such tenants.

Approximately 75% of our site rental costs of operations, exclusive of depreciation, amortization, and accretion, which is shown separately, consists of ground lease expenses, and the remainder includes employee compensation or related benefit costs, property taxes, repairs and maintenance, and utilities. Assuming current leasing activity levels, our operating expenses generally tend to escalate at approximately the rate of inflation. We seek to add tenants to our existing towers at low incremental operating cost, delivering high incremental returns to our business. Once constructed, our towers require minimal sustaining capital expenditures, including maintenance or other non-discretionary capital expenditures, which are typically approximately 1% of net revenues. See note 14 to our consolidated financial statements for a tabular presentation of the rental payments we owe to landlords pursuant to our operating lease agreements.

Services. As part of our effort to provide comprehensive tower solutions, as an ancillary business, we also offer certain services primarily relating to pre-construction site development services. See note 17 to our consolidated financial statements for a discussion of the July 2023 restructuring plan, which included discontinuing installation services as a towers product offering. In 2025, our services and other revenues primarily related to site development services. We seek to grow our services revenues through capitalizing on (1) increased leasing volumes that may result from carrier network upgrades, (2) promoting site development services, (3) expanding the scope of our services, and (4) focusing on tenant service and deployment speed. We do not always provide the site development services for our tenants on our towers as other service providers also provide these services (see also "—Competition" below). Typically, our site development services are non-recurring and are billed on a fixed fee basis, and the terms and pricing of site development services are negotiated separately from our tenant contracts.

Customers. Our largest customers are primarily comprised of wireless carriers that operate national networks.

Our three largest tenants are T-Mobile, AT&T and Verizon Wireless. Collectively, these three tenants accounted for approximately 90% of our 2025 site rental revenues. See "Item 1A. Risk Factors" for risks associated with our dependence on a small number of customers and note 15 to our consolidated financial statements. For 2025, our site rental revenues by tenant were as follows:

Sales and Marketing. Our sales organization markets our towers with the objective of contracting access with tenants to existing towers. We seek to become the critical partner and preferred independent tower provider for our tenants and increase tenant satisfaction relative to our peers by leveraging our (1) existing unique tower footprint, (2) tenant relationships, (3) process-centric approach, and (4) technological tools.

Our sales team is organized based on a variety of factors, including tenant type (such as large wireless carriers, vertical customers and organizations) and geography. A team of national account directors maintains our relationships with our largest tenants. These directors work to develop new business opportunities, as well as to ensure that tenants' needs are efficiently translated into new contracts for our towers. Sales personnel develop and maintain relationships with our tenants that are expanding their networks, entering new markets, seeking new or additional tower offerings, bringing new technologies to market or requiring maintenance or add-on business. In addition to our full-time sales or marketing staff, a number of senior-level employees spend a significant portion of their time on sales and marketing activities and call on existing or prospective tenants.

Competition. We face competition for site rental tenants from various sources, including (1) other independent tower owners or operators, including competitors that own, operate, or manage towers, rooftops, broadcast or transmission towers, (2) owners or operators of small cells, including the operators of our small cell assets following the closure of our Strategic Fiber Transaction, (3) tenants who own or operate their own towers or (4) new alternative deployment methods for towers.

Some of our largest competitors are American Tower Corporation and SBA Communications Corporation. We believe that location, existing tower footprint, deployment speed, quality of service, expertise, reputation, capacity and price have been and will continue to be the most significant competitive factors affecting our businesses. See "Item 1A. Risk Factors" for a discussion of competition in our industry.

Competitors to our services offering can include site acquisition consultants, zoning consultants, real estate firms, right-of-way consulting firms, construction companies, tower owners or managers, radio frequency engineering consultants, our tenants' internal staff or contractors, or telecommunications equipment vendors who can provide turnkey site development services through multiple subcontractors. We believe that our tenants base their decisions on the outsourcing of services on criteria such as a company's experience, record of accomplishment, reputation, price and time for completion of a project.

Sustainability

Our multi-tenant towers model results in the use of fewer resources, including water, energy, metals and other materials, than would otherwise be needed to construct and maintain towers under a single-tenant infrastructure model. We are committed to operating responsibly and ethically and considering social and environmental impacts as we make business decisions. We currently maintain annual sustainability targets in our senior unsecured credit facility.

The Nominating and Governance Committee assists the board of directors with sustainability oversight. Our executive management team and senior management keep our board of directors apprised of our sustainability priorities, goals and initiatives.

Additional information regarding our sustainability initiatives and progress is also available through the Investors section of our website at https://investor.crowncastle.com. The information on our website, including our sustainability reports, is not, and shall not be deemed to be, incorporated by reference into this 2025 Form 10-K or any other filings with the SEC unless expressly noted in any such other filings.

Human Capital

The people who work for Crown Castle are essential to our ability to execute on our strategy. As of January 31, 2026, we employed approximately 4,000 people, including approximately 2,500 people recorded in our discontinued operations. All of our employees are based in the U.S. See note 18 to our consolidated financial statements for a discussion of the 2026 Restructuring Plan, which will reduce our employee headcount. From time to time, we also add contingent workers to support our business.

We believe attracting, developing and retaining talented employees is paramount to serving our customers and our communities and creating value for our stockholders. We also periodically conduct company-wide employee surveys to help us understand how our employees feel about working at our company and track the results to inform our human capital strategies. We focus on building and retaining a strong and innovative workforce with a variety of backgrounds, experiences and points of view.

The well-being of our employees is a crucial element of our safety culture, employee engagement and productivity. We offer a comprehensive total rewards package which includes market-based pay, performance-based annual incentive awards, healthcare and retirement benefits, mental health benefits, parental and family leave, holiday and paid time off and tuition assistance. We further invest in our employees' professional growth and development by providing resources and opportunities to hone their skills and expand their subject-matter expertise, which empowers them to advance their careers and enables our business to prosper.

We are not a party to any collective bargaining agreements and have not experienced any strikes or work stoppages. See "Item 1A. Risk Factors" and note 17 to our consolidated financial statements for further discussion of our 2023 and 2024 Restructuring Plans, which resulted in a reduction of total employee headcount in prior years.

Regulatory and Environmental Matters

We are required to comply with a variety of federal, state and local regulations and laws in the U.S., including FCC and Federal Aviation Administration ("FAA") regulations and those discussed under "—Environmental" below. To date, we have not incurred any material fines or penalties or experienced any material adverse effects to our business as a result of any domestic or international regulations, including any environmental regulations. The summary below is based on regulations currently in effect, and such regulations are subject to review or modification by the applicable governmental authority from time to time. If we fail to comply with applicable laws and regulations, we may be fined or lose our rights to conduct some of our business.

Federal Regulations. Both the FCC and the FAA regulate towers used for wireless communications, radio, or television broadcasting. Such regulations control the siting, construction, modification, lighting, and marking of towers and may, depending on the characteristics of particular towers, require the registration of tower facilities with the FCC and the issuance of determinations confirming no hazard to air traffic. Wireless communications devices operating on towers are separately regulated and independently licensed based upon the particular frequency used. In addition, the FCC and the FAA have developed standards to consider proposals for new or modified tower or antenna structures based upon the height or location, including proximity to airports. Proposals to construct or to modify existing tower or antenna structures above certain heights are reviewed by the FAA to ensure the structure will not present a hazard to aviation, which determination may be conditioned upon compliance with lighting or marking requirements. The FCC requires its licensees to operate communications devices only on towers that comply with FAA rules and are registered with the FCC, if required by its regulations. Where tower lighting is required by FAA regulation, tower owners bear the responsibility of notifying the FAA of any tower lighting outage and ensuring the timely restoration of such outages.

State and Local Regulations. The U.S. Telecommunications Act of 1996 amended the Communications Act of 1934 to preserve state and local zoning authorities' jurisdiction over the siting of communications towers. The law, however, limits state and local zoning authority by prohibiting actions by such authorities that discriminate between different service providers of wireless communications or prohibit altogether (actually or effectively) the provision of wireless communications. Additionally,

the law prohibits state and local restrictions based on the environmental effects of radio frequency emissions to the extent the facilities comply with FCC regulations.

Local regulations include city and other local ordinances (including subdivision and zoning ordinances), approvals for construction, modification and removal of towers, and restrictive covenants imposed by community developers. These regulations vary greatly, but typically require us to obtain prior approval from local officials. Local zoning authorities may render decisions that prevent the construction or modification of towers, or place conditions on such construction or modifications that are responsive to community residents' concerns regarding the height, visibility, or other characteristics of such infrastructure. Over the last several years, the FCC has adopted regulations and 32 states have passed legislation intended to expedite and streamline the deployment of wireless networks, including establishing presumptively reasonable timeframes for reviews by local and state governments. Notwithstanding such developments, decisions of local regulatory authorities and utilities in certain jurisdictions may continue to adversely affect deployment timing and cost.

Certain of our subsidiaries hold state authorizations to provide intrastate telecommunication services in addition to FCC authorization to provide domestic interstate telecommunication services. State authorizations often allow us to deploy such infrastructure in locations where zoning restrictions might otherwise delay, restrict, or prevent building or expanding traditional wireless tower and rooftop sites. See "Item 1A. Risk Factors" for additional information regarding rights to our infrastructure.

Environmental. We are required to comply with a variety of federal, state and local environmental laws and regulations protecting environmental quality, including air and water quality, and wildlife. To date, we have not incurred any material fines or penalties or experienced any material adverse effects to our business as a result of any domestic or international environmental regulations or matters. See "Item 1A. Risk Factors" for additional information regarding compliance with laws and regulations.

The construction of new towers or, in some cases, their modification in the U.S. may be subject to environmental review under the National Environmental Policy Act of 1969, as amended ("NEPA"), which requires federal agencies to evaluate the environmental impact of major federal actions. NEPA regulations require applicants to investigate the potential environmental impact of the proposed tower construction. If the FCC determines that the proposed tower construction or modification presents a significant environmental impact, the FCC is required to prepare an environmental impact statement, which is subject to public comment. Such determination could significantly delay the FCC's approval of the construction or modification.

Our operations are also subject to federal, state and local laws and regulations relating to the management, use, storage, disposal, emission, or remediation of, or exposure to, hazardous or non-hazardous substances, materials, or wastes. As an owner, lessee, or operator of real property, we are subject to certain environmental laws that impose strict, joint-and-several liability for the cleanup of on-site or off-site contamination relating to existing or historical operations; or we could also be subject to personal injury or property damage claims relating to such contamination. In general, our tenant contracts prohibit our tenants from using or storing any hazardous substances on our tower sites in violation of applicable environmental laws and require our tenants to provide notice of certain environmental conditions caused by them.

We are subject to Occupational Safety and Health Administration and similar guidelines regarding employee protection from radio frequency exposure. In recent years, the scientific community has extensively studied low-level radio frequency emissions to determine whether they have any connection to certain negative health effects, such as cancer.

We have compliance programs and monitoring projects designed to promote compliance with applicable environmental laws and regulations. Nevertheless, there can be no assurance that the costs of compliance with existing or future environmental laws will not have a material adverse effect on us.

Summary of Risk Factors

The following summarizes our material risk factors, including risk factors relating to our Fiber Business. However, this summary is not intended to be a comprehensive and complete list of all risk factors identified by the Company. Refer to the following pages of this section for additional details regarding these summarized risk factors.

Risks Relating to Our Business and Industry:

• Our business depends on the demand for our communications infrastructure (including towers, small cells and fiber), driven primarily by demand for data, and we may be adversely affected by any slowdown in such demand. Additionally, a reduction in the amount or change in the mix of network investment by our tenants may materially and adversely affect our business (including reducing demand for our communications infrastructure or services).

• A substantial portion of our revenues is derived from a small number of tenants, and the loss, consolidation or financial instability of any of such tenants may materially decrease revenues, reduce demand for our communications infrastructure and services and impact our dividend per share growth.

• The expansion or development of our business, including through acquisitions, increased product offerings or other strategic opportunities, may cause disruptions in our business, which may have an adverse effect on our business, operations or financial results.

• Our Fiber business model contains certain differences from our Towers business model, resulting in different operational risks. If we do not successfully operate our Fiber business model or identify or manage the related operational risks through the closing of the Strategic Fiber Transaction, such operations may produce results that are lower than anticipated.

• Failure to timely, efficiently and safely execute on our construction projects could adversely affect our business.

• New technologies may reduce demand for our communications infrastructure or negatively impact our revenues.

• If we fail to retain rights to our communications infrastructure, including the rights to land under our towers and the right-of-way and other agreements related to our small cells and fiber, our business may be adversely affected.

• Our services business has historically experienced significant volatility in demand, which reduces the predictability of our results.

• As a result of competition in our industry, we may find it more difficult to negotiate favorable rates on our new or renewing tenant contracts.

• New wireless technologies may not deploy or be adopted by tenants as rapidly or in the manner projected.

• If radio frequency emissions from wireless handsets or equipment on our communications infrastructure are demonstrated to cause negative health effects, potential future claims could adversely affect our operations, costs or revenues.

• Cybersecurity breaches or other information technology disruptions could adversely affect our operations, business, and reputation.

• If we do not continue to make appropriate investments in, and effectively implement and maintain, our information technology systems and digital capabilities, our business and operating results could be adversely affected.

• Our business may be adversely impacted by climate-related events, natural disasters, including wildfires, and other unforeseen events.

• Failure to attract, recruit and retain qualified and experienced employees could adversely affect our business, operations and costs.

• Changes to management, including turnover of our top executives, could have an adverse effect on our business.

• Actions that we are taking, or have completed, to restructure our business in alignment with our strategic priorities may not be as effective as anticipated.

• Actions of activist stockholders could impact the pursuit of our business strategies and adversely affect our results of operations, financial condition, or stock price.

Risks Relating to Our Pending Sale of the Fiber Business:

• The pendency of the sale of our Fiber Business to Zayo and EQT may have an adverse effect on our business, results of operations, cash flows and financial position.

• Completion of the Strategic Fiber Transaction is subject to the conditions contained in the Strategic Fiber Agreement, including regulatory approvals, which may not be received, and separation of the Fiber Business from our current operations, and if these conditions are not satisfied or waived, the transaction will not be completed.

• The failure to complete the planned sale of the Fiber Business to Zayo and EQT could have a material and adverse effect on our business, results of operations, financial condition, cash flows, and stock price.

Risks Relating to Our Debt and Equity

• Our substantial level of indebtedness could adversely affect our ability to react to changes in our business, and the terms of our debt instruments limit our ability to take a number of actions that our management might otherwise believe to be in our best interests. In addition, if we fail to comply with our covenants, our debt could be accelerated.

• We have a substantial amount of indebtedness. In the event we do not repay or refinance such indebtedness, we could face substantial liquidity issues and might be required to issue equity securities or securities convertible into equity securities, or sell some of our assets, possibly on unfavorable terms, to meet our debt payment obligations.

• Sales or issuances of a substantial number of shares of our common stock or securities convertible into shares of our common stock may adversely affect the market price of our common stock.

• Certain provisions of our restated certificate of incorporation ("Charter") and second amended and restated by-laws, as amended ("By-laws") and operative agreements, and domestic and international competition laws may make it more difficult for a third party to acquire control of us or for us to acquire control of a third party, even if such a change in control would be beneficial to our stockholders.

Risks Relating to Corporate Compliance

• If we fail to comply with laws or regulations which regulate our business and which may change at any time, we may be fined or even lose our right to conduct some of our business.

Risks Relating to Our REIT Status

• Future dividend payments to our stockholders will reduce the availability of our cash on hand available to fund future discretionary investments, and may result in a need to incur indebtedness or issue equity securities to fund growth opportunities. In such event, the then current economic, credit market or equity market conditions will impact the availability or cost of such financing, which may hinder our ability to grow our per share results of operations.

• Remaining qualified to be taxed as a REIT involves highly technical and complex provisions of the Code. Failure to remain qualified as a REIT would result in our inability to deduct dividends to stockholders when computing our taxable income, thereby increasing our tax obligations and reducing our available cash.

• Complying with REIT requirements, including the 90% distribution requirement, may limit our flexibility or cause us to forgo otherwise attractive opportunities, including certain discretionary investments and potential financing alternatives.

• REIT related ownership limitations and transfer restrictions may prevent or restrict certain transfers of our capital stock.

Our Company maintains a comprehensive Information Security Program ("IS Program") focused on detection, assessment and mitigation of cybersecurity risks. Our dedicated enterprise security team, led by our Chief Information Security Officer ("CISO"), administers the IS Program and is responsible for identification, investigation and response to cyber threats and vulnerabilities. The enterprise security team also implements, manages, and assesses our Company's cyber policies, standards and procedures, which leverage our team's expertise and the National Institute of Standards and Technology Cybersecurity Framework. We have developed an incident response plan to handle suspected loss of, or unauthorized access to, information. We regularly conduct tabletop exercises, red team exercises, simulations, and other exercises to evaluate the effectiveness of our IS Program and to position our Company for a coordinated, strategic response in the event of an actual security incident. All employees are required to complete cybersecurity trainings and employees in higher-risk roles are required to complete additional customized training tailored to address their specific risk exposure. Our Security Operations Center ("SOC"), which operates 24 hours a day, 365 days a year, is designed to provide visibility of security events across our Company and a mechanism for swiftly addressing cyber threats before they compromise data security. Through a combination of a threat management platform and our team of cybersecurity specialists, our SOC continuously monitors and proactively isolates and analyzes cybersecurity alerts to help us address cybersecurity risks.

The identification, assessment and management of cybersecurity risks are integrated into our existing enterprise risk management ("ERM") framework. Cybersecurity related risks are included in the risk universe that the ERM function evaluates to assess top risks to the enterprise on an annual basis, which are presented to and reviewed by the Audit Committee.

We engage third-party providers to conduct evaluations of our security controls, including through vulnerability assessments and penetration testing, independent audits or consulting on best practices. These evaluations include testing both the design and operational effectiveness of security controls. Additionally, our internal audit team regularly evaluates the effectiveness of the IS Program, with results reported to the board of directors.

We also have policies and procedures in place to manage cybersecurity risks associated with third-party service providers. We impose security requirements on our suppliers, which include maintaining a security management program, complying with information handling requirements, and notifying us in the event of any known or suspected cyber incident. Where appropriate, we assess third-party cybersecurity controls and include security and privacy addenda to our vendor contracts.

Our CISO is informed about and monitors prevention, detection, mitigation, and remediation efforts through regular communication with and reporting from the enterprise security team, many of whom hold cybersecurity certifications, and through the use of technological tools and software and results from third-party assessments. Our CISO has extensive experience assessing and managing cybersecurity programs and risk. Our CISO has over 25 years of cybersecurity experience, including as Chief Technology Officer/CISO and co-founder of two cybersecurity companies and as the Director of Security Services for a large network infrastructure company. The CISO periodically reports to the Audit Committee regarding cybersecurity risk exposure and risk mitigation strategies. The Audit Committee oversees the Company's internal controls regarding cybersecurity and reviews with management the Company’s significant cybersecurity and other information technology risks, controls and procedures, including internal policies, plans and processes to monitor, mitigate or remediate such risks. The board of directors also may review and assess cybersecurity risks as part of its role in overseeing the Company's enterprise risk management, including in connection with its review of the Company's mission critical risks.

While we have not, as of the date of this 2025 Form 10-K, experienced a cybersecurity threat or incident that resulted in a material adverse impact to our business or operations, there can be no guarantee that we will not experience such an incident in the future. See "Item 1A. Risk Factors" for more information on our cybersecurity-related risks.

Towers

We own, lease or manage approximately 40,000 towers geographically dispersed throughout the U.S. Towers are vertical metal structures generally ranging in height from 50 to 300 feet. Our tenants' wireless equipment may be placed on towers, building rooftops and other structures. Our towers are located on tracts of land that support the towers, equipment shelters and, where applicable, guy-wires to stabilize the tower.

See the following for further information regarding our towers:

• "Item 1. Business—Overview" for information regarding our tower and fiber portfolios and the pending sale of the Fiber Business.

• "Item 7. MD&A—Liquidity and Capital Resources—Material Cash Requirements" for information regarding our lease obligations.

• "Schedule III - Schedule of Real Estate and Accumulated Depreciation" for further information on our productive properties.

Approximately 55% of our towers are leased or subleased or operated and managed under master leases, subleases, or other agreements with AT&T and T-Mobile (including those which T-Mobile assumed in its merger with Sprint). We have the option to purchase these towers at the end of their respective lease terms. We have no obligation to exercise such purchase options. See note 5 to our consolidated financial statements and "Item 1A. Risk Factors" for a further discussion.

Substantially all of our towers can accommodate additional tenancy, either as currently constructed or with appropriate modifications. Additionally, if so inclined as a result of a request for a tenant addition, we could generally replace an existing tower with another tower, subject to certain restrictions.

Discontinued Operations

As of December 31, 2025, the Company owned or leased certain properties previously used in its Fiber segment, which has been classified as a discontinued operation. These properties consist of approximately 90,000 route miles of fiber primarily supporting our (1) approximately 105,000 small cell nodes either currently generating revenue or under contract and (2) fiber solutions. The majority of our fiber assets are located in major metropolitan areas, including a presence in most major U.S. markets.

As a result of the Strategic Fiber Transaction, these properties are classified as discontinued operations and are not utilized in the Company's continuing operations. See "Item 1. Business", "Item 7. MD&A—General Overview", and note 3 to our consolidated financial statements for further discussion of the Strategic Fiber Transaction.

Offices

Following the closure of the Strategic Fiber Transaction, which we expect to occur in the first half of 2026, we anticipate having four offices, including our principal corporate headquarters located in Houston, Texas. We believe that our facilities are suitable and adequate to meet our anticipated needs. See "Item 1. Business—Overview" for further discussion of the pending sale of the Fiber Business, which includes the sale of certain of our office buildings.

We are periodically involved in legal proceedings that arise in the ordinary course of business. Most of these proceedings arising in the ordinary course of business involve disputes with landlords, vendors, collection matters involving bankrupt tenants, zoning or siting matters, construction, condemnation, tax, employment, or wrongful termination matters. While the outcome of these matters cannot be predicted with certainty, management does not expect any pending matters to have a material adverse effect on us.

See the disclosure in note 13 to our consolidated financial statements.

PART II

Market Information and Holders

Our common stock is listed and traded on the NYSE under the symbol "CCI."

As of February 19, 2026, there were approximately 509 holders of record of our common stock.

Dividend Policy

We operate as a REIT for U.S. federal income tax purposes. To remain qualified and be taxed as a REIT, we are generally required to annually distribute to our stockholders at least 90% of our REIT taxable income after the utilization of any available NOLs (determined without regard to the dividends paid deduction and excluding net capital gain).

We have updated our capital allocation framework to focus more on free cash flow generation and financial flexibility, which primarily drove our decision to reduce our dividend in the second quarter of 2025. As we grow cash flows, we expect to increase our dividend per share. Whether dividends are to be declared and the amount and timing thereof remain subject to the discretion of our board of directors, based on then-current or anticipated future conditions, including our earnings, net cash generated by operating activities, capital requirements, financial condition, our relative market capitalization, our existing NOLs, or other factors deemed relevant by our board of directors. In addition, our ability to pay dividends is limited under certain circumstances by the terms of our debt instruments. See also "Item 1. Business—Overview," "Item 1. Business—REIT Status," "Item 1A. Risk Factors," "Item 7. MD&A—General Overview—Common Stock Dividend," "Item 7. MD&A—Liquidity and Capital Resources—Financing Activities—Common Stock" and notes 10 and 11 to our consolidated financial statements.

Recent Sales of Unregistered Equity Securities

There were no sales of of unregistered equity securities for the twelve months ended December 31, 2025.

2024 At-the-Market Stock Offering Program

As of February 19, 2026, we had $750 million of gross sales of common stock availability remaining on our 2024 ATM Program. See "Item 7. MD&A—Liquidity and Capital Resources" and note 11 to our consolidated financial statements.

Performance Graph

The following performance graph is a comparison of the five-year cumulative total stockholder return on our common stock against the cumulative total return of the S&P 500 Market Index and the FTSE NAREIT All Equity REITs Index for the period commencing December 31, 2020 and ending December 31, 2025. The performance graph assumes an initial investment of $100.00 and the reinvestment of all dividends in our common stock and in each of the indices. The performance graph and related text are based on historical data and are not necessarily indicative of future performance.

The performance graph above and related text are being furnished solely to accompany this 2025 Form 10-K pursuant to Item 201(e) of Regulation S-K, and are not being filed for purposes of Section 18 of the Exchange Act, and are not to be incorporated by reference into any filing of ours, whether made before or after the date hereof, regardless of any general incorporation language in such filing.

General Overview

Overview

We own, operate and lease shared communications infrastructure. See "Item 1. Business" for a further discussion of our business, including our long-term strategy, our REIT status, certain key terms of our tenant contracts and growth trends in the demand for data.

On March 13, 2025, management signed the Strategic Fiber Agreement to sell our Fiber Business, with Zayo acquiring the fiber solutions business and EQT acquiring the small cell business. Under the Strategic Fiber Agreement, we will receive $8.5 billion in aggregate, subject to certain closing adjustments. The Strategic Fiber Transaction is expected to close in the first half of 2026, subject to certain closing conditions and regulatory approvals. See "Item 1. Business—Overview" for further discussion of the pending sale of the Fiber Business.

As the aforementioned sale represents a material strategic shift for the Company, the Fiber Business' results and net assets are presented herein as discontinued operations and comparable prior periods have been recast to reflect this change. Related to the classification of the Fiber Business as "held for sale", we have recognized a loss from disposal of discontinued operations of approximately $1.6 billion, inclusive of estimated transaction fees, for the year ended December 31, 2025.

Following the classification of the Fiber Business as discontinued operations, we have one reportable segment that constitutes consolidated results of our tower operations. See notes 3 and 15 to our consolidated financial statements for a discussion of discontinued operations and our operating segment. Unless otherwise noted, all activities and amounts reported in this document relate to continuing operations and exclude activities and amounts related to discontinued operations.

Highlights of Business Fundamentals and Results

• Site rental revenues represented 95% of our 2025 net revenues. The vast majority of our site rental revenues is of a recurring nature and has been contracted for in prior years.

• We operate as a REIT for U.S. federal income tax purposes (see "Item 1. Business—REIT Status" and notes 2 and 10 to our consolidated financial statements)

• Potential growth resulting from the increasing demand for data

◦We expect existing and potential new tenant demand for our towers will result from (1) new technologies, (2) increased usage of mobile entertainment, mobile internet, and machine-to-machine applications, (3) adoption of other emerging and embedded wireless devices (including smartphones, laptops, tablets, wearables and other devices), (4) increasing smartphone penetration, (5) wireless carrier focus on expanding both network quality and capacity, (6) the adoption of other bandwidth-intensive applications (such as cloud services, artificial intelligence and video communications), (7) the availability of additional spectrum and (8) increased government initiatives to support connectivity throughout the U.S.

◦We expect U.S. wireless carriers will continue to focus on improving network quality and expanding capacity (including through 5G initiatives). We believe our towers provide an efficient and cost-effective solution to our wireless tenants' growing infrastructure needs.

◦Tenant additions on our towers are achieved at a low incremental operating cost, delivering high incremental returns.

◦Substantially all of our towers can accommodate additional tenancy, either as currently constructed or with appropriate modifications.

• Returning cash flows provided by operations to stockholders in the form of dividends (see also "Item 1. Business—Strategy")

◦During 2025, we paid common stock dividends totaling approximately $2.1 billion.

• Investing capital efficiently to grow cash flows

◦We had discretionary capital expenditures of $149 million for the year ended December 31, 2025, predominately related to improvements to existing towers to support additional tenants and purchases of land underneath our towers.

◦We expect to continue to construct and acquire new towers that we expect will generate future cash flow growth and attractive long-term returns by adding tenants to those assets over time.

◦We expect to continue to acquire land interests relating to land under our towers.

• Site rental revenues under long-term tenant contracts

◦Our tenant contracts have initial terms generally between five to 15 years with contractual escalators and multiple renewal periods generally between five to 10 years each, exercisable at the option of the tenant.

◦As of December 31, 2025, our weighted-average remaining term was approximately six years, exclusive of renewals exercisable at the tenants' option, currently representing approximately $23.7 billion of expected future cash inflows, exclusive of amounts due under the Master Lease Agreement and underlying agreements with DISH. See "Item 7. MD&A—General Overview—Outlook Highlights" for further discussion.

• Majority of our revenues from large wireless carriers

◦For the year ended December 31, 2025, approximately 90% of our site rental revenues were derived from T-Mobile, AT&T and Verizon Wireless. See "Item 1A. Risk Factors" and note 15 to our consolidated financial statements for a further discussion of our largest customers.

◦During 2025, our site rental revenues decreased approximately $200 million as a result of non-renewals related to the network consolidation of T-Mobile and Sprint.

• Majority of land under our towers under long-term control

◦For the year ended December 31, 2025, approximately 90% of our towers Adjusted Site Rental Gross Margin and approximately 80% of our towers Adjusted Site Rental Gross Margin was derived from towers located on land that we own or control for greater than 10 and 20 years, respectively. The aforementioned percentages include towers located on land that is owned, including through fee interests and perpetual easements, which represented approximately 40% of our towers Adjusted Site Rental Gross Margin.

• Minimal sustaining capital expenditure requirements

◦For the year ended December 31, 2025, sustaining capital expenditures represented less than 1% of net revenues.

• Debt portfolio with long-dated maturities extended over multiple years, with the vast majority of such debt having a fixed rate (see note 8 to our consolidated financial statements and "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for a further discussion of our debt)

◦As of December 31, 2025, our outstanding debt had a weighted average interest rate of 3.9% and weighted average maturity of approximately six years (assuming anticipated repayment dates on certain debt).

◦As of December 31, 2025, 84% of our debt has fixed rate coupons.

◦Our debt service coverage and leverage ratios are within their respective financial maintenance covenants. See "Item 7. MD&A—Liquidity and Capital Resources—Debt Covenants" for a further discussion of our debt covenants.

• During 2025, we repaid in full certain of our debt (see note 8 to our consolidated financial statements and "Item 7. MD&A—Liquidity and Capital Resources—Financing Activities" for further discussion of our debt transactions)

• Significant cash flows from operations

◦Net cash provided by operating activities was $3.1 billion for the year ended December 31, 2025.

◦In addition to the positive impact of contractual escalators, we expect to grow our core business of providing access to our towers as a result of future anticipated additional demand.

• 2023 and 2024 Restructuring Plans

◦There were no restructuring charges in 2025 relating to either the 2023 Restructuring Plan or the 2024 Restructuring Plan. See note 17 to our consolidated financial statements for further discussion of the 2023 Restructuring Plan and 2024 Restructuring Plan.

Common Stock Dividend

During the first quarter of the year ended 2025, we paid a common stock dividend of $1.565 per share

Our primary exposures to market risks are related to changes in interest rates, which may adversely affect our results of operations and financial position. We seek to manage exposure to changes in interest rates where economically prudent to do so by utilizing fixed rate debt. As of December 31, 2025 and December 31, 2024 we had no interest rate swaps.

Interest Rate Risk

Our interest rate risk as of December 31, 2025 relates primarily to the impact of interest rate movements on the following:

• the potential refinancing of our $24.3 billion in existing debt, compared to $24.1 billion as of December 31, 2024;

• our $3.9 billion of floating rate debt, compared to $2.5 billion as of December 31, 2024, representing approximately 16% and 10% of total debt respectively; potential future borrowings of incremental debt, including borrowings under our 2016 Credit Facility and issuances under our CP Program; and

• potential future borrowings of incremental debt, including borrowings under our 2016 Credit Facility and issuances under our CP Program.

See "Item 1a. Risk Factors" for a further discussion of risks stemming from interest rate increases.

Sensitivity Analysis. We manage our exposure to market interest rates on our existing debt by controlling the mix of fixed and floating rate debt. As of December 31, 2025, we had $3.9 billion of floating rate debt. A hypothetical unfavorable fluctuation in market interest rates on our existing floating rate debt of 1/4 of a percentage point over a 12-month period would increase our interest expense by approximately $10 million.

Potential Future Borrowings of Incremental Debt. We typically do not hedge our exposure to interest rates on potential future borrowings of incremental debt for a substantial period prior to issuance. See "Item 7. MD&A—Liquidity and Capital Resources" regarding our liquidity strategy.

Potential Refinancing of Existing Debt. Our contractual debt maturities over the next 12 months consist of Commercial Paper Notes that may be outstanding from time to time, the 4.450%, 3.700%, and 1.050% Senior Notes and principal payments on certain outstanding debt. See below for additional discussion as well as a tabular presentation of our scheduled contractual debt maturities as of December 31, 2025.

Future Principal Payments and Interest Rates

The following table provides information about our market risk related to changes in interest rates relating to the Company's continuing operations. The future principal payments and weighted-average interest rates are presented as of December 31, 2025. These debt maturities reflect final maturity dates, and do not consider the impact of the principal payments that will commence following the anticipated repayment dates of certain debt (see footnotes (b) and (d)). The information presented below regarding the variable rate debt is supplementary to our sensitivity analysis regarding the impact of changes in the interest rates. See note 8 to our consolidated financial statements for additional information regarding our debt.

(a)The fair value of our debt is based on indicative quotes, non-binding quotes from brokers that require judgment to interpret market information, including implied credit spreads for similar borrowings on recent trades or bid/ask offers. These fair values are not necessarily indicative of the amount, which could be realized in a current market exchange.

(b)The impact of principal payments that will commence following an anticipated repayment date is not considered (see footnote (d) below). The Tower Revenue Notes, Series 2018-2 have a principal amount of $750 million, with an anticipated repayment date in 2028.

(c)The average interest rate represents the weighted-average stated coupon rate (see also footnote (d)).

(d) If the Tower Revenue Notes, Series 2018-2 are not repaid in full by the anticipated repayment date, the interest rate increases by approximately 5% per annum and monthly principal payments commence using the Excess Cash Flow (as defined in the indenture governing the Tower Revenue Notes, Series 2018-2) of the issuers of the Tower Revenue Notes, Series 2018-2. The Tower Revenue Notes, Series 2018-2 are presented based on their contractual maturity date in 2048 and include the impact of an assumed 5% increase in interest rate that would occur following the anticipated repayment date but exclude the impact of monthly principal payments that would commence using Excess Cash Flow of the issuers of the Tower Revenue Notes, Series 2018-2. The full year 2025 Excess Cash Flow of the issuers of the Tower Revenue Notes, Series 2018-2 was approximately $1.0 billion. We currently expect to refinance or repay these notes on or prior to the anticipated repayment date.

(e) Consists of our 2016 Revolver and senior unsecured term loan A facility ("2016 Term Loan A" and, collectively, "2016 Credit Facility"), which mature in 2027, and issuances under our CP Program. See note 8 to our consolidated financial statements for information regarding potential upward or downward adjustments to the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility if we achieve specified annual sustainability targets or fail to meet annual sustainability thresholds. Each annual period presented assumes the downward adjustments in the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility.

(f) Predominately consists of outstanding indebtedness under our CP Program. Such amounts may be issued, repaid or re-issued from time to time.

We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

(a) Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

In connection with the preparation of the 2025 Form 10-K, the Company's management conducted an evaluation, under the supervision and with the participation of the Company's Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), of the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended ("Exchange Act")). Based upon their evaluation, the CEO and CFO concluded that as of December 31, 2025, the Company's disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by the Company in the reports filed or submitted by it under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and to provide reasonable assurance that information required to be disclosed by the Company in such reports is accumulated and communicated to the Company's management, including its CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

(b) Management's Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) for the Company. Under the supervision and with the participation of the Company's CEO and CFO, management assessed the effectiveness of the Company's internal control over financial reporting based on the framework described in Internal Control – Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. The Company's internal control over financial reporting includes those policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles in the United States of America, and that receipts and expenditures of the Company are being made only in accordance with authorization of management and directors of the Company; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use or disposition of the Company's assets that could have a material effect on the financial statements.

Management has assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2025. Based on the Company's assessment, management has concluded that the Company's internal control over financial reporting was effective as of December 31, 2025 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles in the United States of America.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2025 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears in Part II, Item 8 of the 2025 Form 10-K.

(c) Changes in Internal Control Over Financial Reporting

There have not been any changes in the Company's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the most recent fiscal quarter that have materially affected or are reasonably likely to materially affect the Company's internal control over financial reporting.

(d) Limitations on the Effectiveness of Controls

Because of its inherent limitations, the Company's internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

During the fiscal three months ended December 31, 2025, none of the Company’s directors or officers (as defined in Rule 16a1(f) under the Exchange Act) adopted or terminated any contract, instruction, or written plan for the purchase or sale of the Company’s securities intended to satisfy the conditions of the affirmative defense provided by Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement,” as defined in Item 408(a) of Regulation S-K.
