Material Changes vs. Prior Period
- Revenue Growth: Total revenue increased 5% year-over-year. Growth was driven by the Services segment (+75%), Data Centers (+14%), Africa & APAC (+18%), and Europe (+12%). The U.S. & Canada segment remained flat (0%), while Latin America declined 4% primarily due to foreign currency translation impacts and increased revenue reserves.
- Profitability: Net income increased 15% to $2.63 billion, largely due to the absence of the $978 million loss from discontinued operations recorded in 2024. Adjusted EBITDA grew 5% to $7.13 billion.
- Foreign Currency Impact: The company recorded $809.4 million in foreign currency losses in 2025, compared to $308.3 million in gains in 2024, significantly impacting "Other expense."
- Divestitures: Completed the sale of South Africa Fiber assets in 2025, resulting in a $53.6 million gain. The India business (ATC TIPL) was sold in 2024 and is reported as discontinued operations.
Guidance, Outlook, and Risks
Management Commentary and Outlook
- Capital Allocation: The company expects 2026 total capital expenditures to range between $1.795 billion and $1.905 billion. This includes discretionary projects, ground lease purchases, and data center construction.
- Distributions: As a REIT, the company expects to distribute at least 90% of REIT taxable income. Total distributions declared in 2025 were $3.18 billion ($6.80 per share). The company expects 2026 total distributions to be approximately $3.3 billion.
- Share Repurchases: The company repurchased $364.6 million of stock in 2025. As of February 2026, $1.6 billion remains available under the 2017 Buyback program.
Key Risks and Contingencies
- Customer Disputes:
- AT&T Mexico: Engaged in arbitration regarding lease calculations. AT&T Mexico represented ~$300 million in 2025 revenue. The company recorded $30 million in reserves in 2025 and expects to record future reserves until settlement.
- DISH: DISH notified the company of an intent to be excused from its Strategic Collocation Agreement (SCA) and is in default as of January 2026. DISH represented ~2% of total property revenue in 2025. The company has filed a complaint seeking a declaratory judgment.
- Customer Concentration: The top four customers (T-Mobile, AT&T, Verizon, Telefónica) accounted for 59% of total revenues in 2025.
- Foreign Operations: Significant exposure to foreign currency fluctuations and political/economic risks in international markets (e.g., Brazil, Mexico, Nigeria).
- Goodwill Impairment: Recorded a $6.5 million goodwill impairment charge related to the Bangladesh reporting unit in 2025.
Investor Verification Checklist
- Dispute Resolution: Monitor the status of the AT&T Mexico arbitration and the DISH litigation, as adverse outcomes could materially impact revenue and reserves.
- Foreign Currency Sensitivity: Verify the impact of currency fluctuations on Latin American and African segments, which drove a significant portion of the "Other expense" variance.
- Debt Maturity Wall: Review the schedule of debt maturities, noting $3.4 billion in current portion of long-term obligations due in 2026.
- Data Center Growth: Assess the performance of the Data Centers segment, which grew 14% in revenue and is a key strategic growth driver.
- REIT Compliance: Confirm that distribution levels remain sufficient to maintain REIT tax status, particularly given the high payout ratio.
