This Quarterly Report on Form 10-Q (this “Quarterly Report”) contains statements about future events and expectations, or “forward-looking statements,” which relate to our goals, beliefs, strategies, plans or current expectations and other statements that are not of historical facts. For example, when we use words such as “project,” “plan,” “believe,” “anticipate,” “expect,” “forecast,” “estimate,” “intend,” “should,” “would,” “could,” “may” or other words that convey uncertainty of future events or outcomes, we are making forward-looking statements. Certain important factors may cause actual results to differ materially from those indicated by our forward-looking statements, including those factors set forth under the caption “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”). Forward-looking statements represent management’s current expectations, beliefs and assumptions, and are inherently uncertain. We do not undertake any obligation to update our forward-looking statements.

The discussion and analysis of our financial condition and results of operations that follow are based upon our consolidated and condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of our financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates and such differences could be material to the financial statements. This discussion should be read in conjunction with our consolidated and condensed consolidated financial statements herein and the accompanying notes, information set forth under the caption “Critical Accounting Policies and Estimates” in the 2024 Form 10-K, and in particular, the information set forth therein under Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

During the fourth quarter of 2024, following recent divestitures, including the ATC TIPL Transaction (as defined below), and changes to our organizational structure, we reviewed and changed our reportable segments. Our APAC property segment and our Africa property segment were combined into the Africa & APAC property segment. As a result, we now report our results in six segments: U.S. & Canada property (which includes all assets in the United States and Canada, other than our data center facilities and related assets), Africa & APAC property, Europe property, Latin America property, Data Centers and Services. In evaluating financial performance in each business segment, management uses, among other factors, segment gross margin and segment operating profit (see note 14 to our consolidated and condensed consolidated financial statements included in this Quarterly Report). Historical financial information included in Management’s Discussion and Analysis of Financial Condition and Results of Operations has been adjusted to reflect the change in reportable segments.

In 2023, we initiated a strategic review of our India business, as further discussed below under “Results of Operations—Income from Discontinued Operations, Net of Taxes.” The strategic review concluded in January 2024 with the signed agreement for the ATC TIPL Transaction. The ATC TIPL Transaction received all government and regulatory approvals during the three months ended September 30, 2024. On September 12, 2024, we completed the ATC TIPL Transaction and received total consideration of 182 billion INR (approximately $2.2 billion). ATC TIPL’s operating results are presented as discontinued operations. See discussion below and note 15 to our consolidated and condensed consolidated financial statements included in this Quarterly Report (“Note 15”) for further discussion. Historical financial information included in Management’s Discussion and Analysis of Financial Condition and Results of Operations has been adjusted to reflect the operating results of ATC TIPL as discontinued operations for all periods presented.

Overview

We are one of the largest global real estate investment trusts and a leading independent owner, operator and developer of multitenant communications real estate. Our primary business is the leasing of space on communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in a number of other industries. In addition to the communications sites in our portfolio, we manage rooftop and tower sites for property owners under various contractual arrangements. We also hold other telecommunications infrastructure and property interests that we lease primarily to communications service providers and third-party tower operators, and, as discussed further below, we hold a portfolio of highly interconnected data center facilities and related assets in the United States. Our customers include our tenants, licensees and other payers. We refer to the business encompassing the above as our property operations, which accounted for 97% of our total revenues for the three months ended March 31, 2025 and includes our U.S. & Canada property, Africa & APAC property, Europe property and Latin America property segments and Data Centers segment.

We also offer tower-related services in the United States, including site application, zoning and permitting, structural and mount analyses, and construction management, which primarily support our site leasing business, including the addition of new tenants and equipment on our sites.

The following table details the number of communications sites, excluding managed sites, that we owned or operated as of March 31, 2025:

Interest Rate Risk

Changes in interest rates can cause interest charges to fluctuate on our variable rate debt. Variable rate debt as of March 31, 2025 consisted of $50.0 million under the 2021 Multicurrency Credit Facility, $360.0 million under the 2021 Credit Facility and $1.0 billion under the 2021 Term Loan. A 10% increase in current interest rates would result in an additional $1.9 million of interest expense for the three months ended March 31, 2025.

Foreign Currency Risk

We are exposed to market risk from changes in foreign currency exchange rates primarily in connection with our foreign subsidiaries and joint ventures internationally. Any transaction denominated in a currency other than the U.S. Dollar is reported in U.S. Dollars at the applicable exchange rate. All assets and liabilities are translated into U.S. Dollars at exchange rates in effect at the end of the applicable fiscal reporting period and all revenues and expenses are translated at average rates for the period. The cumulative translation effect is included in equity as a component of Accumulated other comprehensive loss. We may enter into additional foreign currency financial instruments in anticipation of future transactions to minimize the impact of foreign currency exchange rate fluctuations. For the three months ended March 31, 2025, 31% of our revenues and 37% of our total operating expenses were denominated in foreign currencies.

As of March 31, 2025, we have incurred intercompany debt that is not considered to be permanently reinvested and similar unaffiliated balances that were denominated in a currency other than the functional currency of the subsidiary in which it is recorded. As this debt had not been designated as being a long-term investment in nature, any changes in the foreign currency exchange rates will result in unrealized gains or losses, which will be included in our determination of net income. An adverse change of 10% in the underlying exchange rates of our unsettled intercompany debt and similar unaffiliated balances would result in $31.3 million of unrealized losses that would be included in Other income (expense) in our consolidated statements of operations for the three months ended March 31, 2025. As of March 31, 2025, we have 7.5 billion EUR (approximately $8.1 billion) denominated debt outstanding. An adverse change of 10% in the underlying exchange rates of our outstanding EUR debt would result in $0.9 billion of foreign currency losses that would be included in Other expense in our consolidated statements of operations for the three months ended March 31, 2025.

Disclosure Controls and Procedures

We have established disclosure controls and procedures designed to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this Quarterly Report. Based on this evaluation, our principal executive officer and principal financial officer concluded that these disclosure controls and procedures were effective as of March 31, 2025 and designed to ensure that the information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the requisite time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the fiscal quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

We periodically become involved in various claims and lawsuits that are incidental to our business. While our management, after consultation with counsel, currently believes the ultimate outcome of these legal proceedings, individually and in the aggregate, will not have a material adverse impact on our consolidated financial position, results of operations or liquidity, litigation is subject to inherent uncertainties. Were an unfavorable ruling to occur, there exists the possibility of a material adverse impact on our financial condition and results of operations.

There were no material changes to the risk factors disclosed in Item 1A of the 2024 Form 10-K.

(c) Insider Trading Arrangements and Policies

Rule 10b5-1 Plans

Eugene M. Noel, our Executive Vice President and Chief Operating Officer, entered into a pre-arranged stock trading plan on February 26, 2025. Mr. Noel’s plan provides for the potential exercise of vested stock options and the associated sale of up to 41,209 shares of our common stock between May 28, 2025 and March 2, 2026.

This trading plan was entered into during an open insider trading window and is intended to satisfy the affirmative defense of Rule 10b5-1 under the Exchange Act and our policies regarding transactions in our securities. Generally, this trading plan pre-establishes the amounts, prices and dates of future purchases or sales of our stock, including shares issued upon the exercise or vesting of equity awards. Under this trading plan, the individual officer relinquishes control over the transactions once the trading plan is put into place. Accordingly, sales under this plan may occur at any time, including possibly before, simultaneously with, or immediately after, significant Company events.
