Paragraphs with nothing like them in last year's 10-K
21 paragraphs in Risk Factors of the 10-K filed Feb 24, 2026 with nothing like them in the 10-K filed Feb 25, 2025. Quoted exactly. Paragraphs that were only edited are under 10-K change.
Compared with the Risk Factors in the latest 10-K of the other 29 Real estate companies: a paragraph with at least half its words the same at another company is called similar, and the companies are listed under it. A paragraph most of them have is marked boilerplate. No line means no other company has one like it. This counts text; it does not say how serious a risk is.
Our business, results of operations and financial condition could be negatively impacted by disputes with our customers.

For example, we are currently engaged in a legal dispute (the “Arbitration”) with one of our customers in Mexico, AT&T Comunicaciones Digitales, S. de R.L. de C.V. and related entities (collectively, “AT&T Mexico”). AT&T Mexico, which represented approximately $300 million of tenant revenue in 2025, is challenging the calculation of the monthly lease amount established under our Master Lease Agreement with AT&T Mexico (the “MLA”), as well as certain other provisions of the MLA, seeking rent abatement both retroactively and prospectively, and withheld certain tower rents during 2025. As previously discussed, on September 23, 2025, we and AT&T Mexico reached an agreement pursuant to which AT&T Mexico has remitted payment of the majority of the withheld tower rents and has resumed monthly payments of the majority of its owed tower rents. The remainder of the outstanding receivables and the future monthly unpaid tower rent amounts are being deposited into an irrevocable escrow account, overseen by an independent trustee, to be released in accordance with a final ruling in the Arbitration or by mutual consent of us and AT&T Mexico. We incurred approximately $30 million of reserves during the year ended December 31, 2025 related to this customer. We expect to record future reserves until the Arbitration is settled.
Additionally, on September 24, 2025, one of our U.S. customers, DISH Wireless L.L.C., a subsidiary of DISH Network Corporation (“DISH”), delivered a notice purporting to be excused from its contractual obligations under our Strategic Collocation Agreement entered into in March 2021 (the “SCA”). DISH has failed to meet its payment obligations, and as of January 2026 is in default under the SCA. We filed a complaint seeking a declaratory judgment that DISH has not been excused from its obligations under the SCA, that the SCA remains in full force and effect, and that DISH remains required to perform all of its obligations under the SCA. This matter is still pending.
The outcomes of these matters are uncertain, and there can be no assurance that our positions will be upheld. Adverse rulings in one or both of these disputes could have a material negative impact on our results of operations and financial condition.

We have a substantial amount of indebtedness. As of December 31, 2025, we had approximately $37.2 billion of consolidated debt and the ability to borrow additional aggregate amounts of approximately $9.6 billion under our $6.0 billion senior unsecured multicurrency revolving credit facility, as amended and restated in December 2021, as further amended (the “2021 Multicurrency Credit Facility”) and our $4.0 billion senior unsecured revolving credit facility, as amended and restated in December 2021, as further amended (the “2021 Credit Facility”), net of approximately $36.8 million of outstanding undrawn letters of credit.

Additionally, our Board has approved a share repurchase program allowing us to repurchase common stock through various methods, including open market purchases. The program does not require any specific amount or number of shares to be repurchased, and management will determine timing and volume based on market conditions and other factors. Repurchases could impact stock price, liquidity and cash reserves, potentially affecting future growth opportunities. While intended to enhance long-term shareholder value, there is no guarantee of success, and short-term price fluctuations could reduce the program’s effectiveness. Additionally, our share repurchase program could diminish our available cash, which may impact our ability to finance future growth and pursue possible future strategic opportunities and acquisitions.

Our data centers segment is also subject to various federal, state and local environmental and health and safety laws and regulations in the United States, as set forth in Item 1A of this Annual Report under the caption “Risk Factors— Our data center segment contains certain operational differences from our tower leasing operations resulting in different operational risks. If we do not successfully operate our data center segment or identify or manage the related operational risks, such operations may produce results that are lower than anticipated.”

Globally, the frequency, severity and sophistication of cybersecurity incidents have increased, and these trends will likely continue, especially during times of geopolitical tension or instability among countries from which a number of recent cybersecurity events have been alleged to have originated. Such cyber-attacks could be in the form of espionage, phishing campaigns and otherwise. Additionally, the use of AI technologies has led to increased exposure to cybersecurity threats globally. AI systems may be used by threat actors to exploit vulnerabilities more efficiently or to facilitate increasingly
sophisticated cyberattacks, any of which could result in data breaches, operational disruptions or liability. We are continuously evaluating and enhancing our cybersecurity and information security systems and creating new systems and processes. However, there can be no assurance that these measures are or will be effective in preventing or limiting the impact of future

Our data center segment contains certain operational differences from our tower leasing operations, resulting in different operational risks. If we do not successfully operate our data center segment or identify or manage the related operational risks, such operations may produce results that are lower than anticipated.
Similar paragraph at 1 of 29 other Real estate companies: CCIOver the last five years, we have significantly expanded our data centers business, which is a much less mature business for us than our tower leasing operations. Our data centers segment represented 10% of our total revenues for the year ended December 31, 2025. The business model for our data center business contains certain differences from our business model for our tower leasing operations, including those relating to customer base, competition, contract terms (including requirements for service level agreements regarding data center uptime and network performance), upfront capital requirements, ongoing capital improvements, expenditures required for maintenance of data center power, cooling and network equipment, landlord demographics, deployment and ownership of certain network assets, operational oversight requirements and government regulations. As we continue to invest in our data center segment, we may be required to commit significant operational and financial resources to data center developments, generally 12 to 18 months before securing customer contracts. Additionally, investments in data centers developments require a longer time to achieve stabilization and underwritten development yields than the development of new towers. If customer demand in our markets is insufficient once the data centers are built, we may have difficulty realizing expected or reasonable returns on these investments.
Moreover, we rely on third parties, governmental entities and suppliers to provide sufficient power for our data centers and to support future expansion, which is different than our tower leasing operations. Difficulties in securing contracted energy or obtaining adequate capacity for future data center developments may adversely affect our operations, financial performance and customer relationships. Power constraints, delays, unfavorable contractual terms and increased costs from utility providers could limit our ability to identify suitable sites and expand, particularly as evolving technologies, such as AI, increase power requirements. Our ability to scale remains dependent on reliable energy access amid rising electrification trends and associated infrastructure challenges.
Additionally, we are currently engaging in, or contemplating, data center expansions and new ground-up data center builds in new and existing markets. The construction projects associated with such expansion initiatives expose us to many risks that differ from those for our tower leasing operations, such as delays in site readiness, utility power and power grid constraints, the potential requirement for on-site power generation solutions where utility power is unavailable, lack of availability and delays for data center equipment, unexpected budget changes and unanticipated customer requirements that would necessitate alternative data center design, making our sites less desirable or leading to increased costs in order to make necessary modifications or retrofits. Construction projects are dependent on permitting from public agencies and utility companies. Any delay in permitting could affect our growth. While we do not currently anticipate any material long-term negative impact on our business due to construction delays, these types of delays and stoppages related to permitting from public agencies and utility companies could have an adverse effect on our revenue or growth.
Furthermore, we also may face pressure from certain stakeholders, such as the communities in which we operate, who are increasingly focused on climate change and shortages of power, land and water resources, which are different pressures than those faced by our tower leasing operations. Such pressure could lead to federal, state or municipal governments imposing more stringent regulations and requirements to control the growth and development of data centers in their communities. New builds and further expansion of data center operations in such markets are increasingly being evaluated and approvals, if required, may only be granted where we are not only able to demonstrate that our operations are efficient in their use of energy and water but also that they have and/or will bring positive and significant environmental, economic and social impact to their local community.

Our business depends on effective data governance, and failures in our data governance frameworks could adversely affect our operations.
Our business depends on our ability to appropriately collect, manage, integrate and use data across our operations. We maintain data governance policies, steering committees and standards and controls designed to promote data quality and appropriate use. However, these frameworks may not operate as intended or keep pace with changes in our business, technology or regulatory environment. Insufficient controls over data access and usage (such as role-based entitlements, segregation of duties and monitoring) increase the likelihood of the perpetration of fraud, unauthorized changes to site inventories or records, data leakage involving sensitive customer, landlord or vendor information and operational disruptions to provisioning, energy management and service-level performance. Any material failure in these areas could negatively impact customers, drive delays and increase operating costs. Additionally, we utilize AI technologies that rely on access to and use of significant amounts of data, which in some cases include sensitive information. Inadequate safeguards over AI training data and model inputs or outputs could result in misuse of such data, algorithmic bias or violations of applicable privacy and data protection requirements. Moreover, errors or limitations in AI systems may unintentionally expose sensitive information, which could subject us to regulatory action, contractual claims or reputational harm. Failures or deficiencies in our data governance practices could result in inaccurate or inconsistent data, impaired decision‑making, operational disruptions, regulatory noncompliance or reputational harm, which could adversely affect our business.
The transformation initiatives we undertake may not deliver the results we expect.
