Summary
Summary of the 10-K filed February 25, 2025. Cited figures are marked; the original filing is the authoritative source.
American Tower (AMT) closed 2024 with total revenues of $10.13 billiona (up 1% year over year), Adjusted EBITDA of $6.81 billion (up 2%), and AFFO attributable to common stockholders of $4.93 billion (up 7%).
Growth was tempered by foreign currency headwinds in Africa, Latin America and Nigeria, while the U.S. & Canada segment was flat on revenue as expected churn from T-Mobile's legacy Sprint lease cancellations is projected to stay elevated through 2025. Reported net income rose to $2.28 billionb, but this was driven largely by favorable non-cash items: a $378 million other income gain (mostly FX and equity securities), a $730 million lower depreciation expense from a tower useful-life extension from 20 to 30 years, and offset by a $978 million loss from discontinued operations, which includes a $1.2 billion loss on the sale of the India business (ATC TIPL) completed September 2024. The balance sheet deleveraged meaningfully.
Total debt fell to about $36.8 billionc, and the company used ATC TIPL proceeds (about $2.2 billion) and cash flow to repay revolving borrowings and maturing notes. Liquidity was $12.0 billion at year-end, and investment-grade ratings were maintained. Operating cash flow rose to $5.29 billion, while capex was $1.6 billion, and distributions to common stockholders totaled $3.1 billion ($6.56/share).
Management guides 2025 capex to $1.635d-1.745 billion and expects a 2025 distribution total of $3.2 billion. Investors should note the company's large non-cancellable lease backlog (about $54 billion), its concentration in four customers (60% of revenue), and significant foreign currency exposure (32% of revenue denominated in foreign currencies). Key watch items include the T-Mobile churn trajectory, the potential REIT Pillar 2 tax exposure starting in 2026 if AMT does not qualify as a Real Estate Investment Vehicle, ongoing data center expansion (29 facilities, about 3.3 million NRSF), and continued execution of the portfolio simplification strategy, including the pending sale of South Africa fiber for about $133 million.
02—Key points
Key Highlights
- Total revenue of $10.13B (+1% YoY); property operations are 98% of revenue, with U.S. & Canada (52%) the largest segment and Data Centers growing 11% to $925M.
- Adjusted EBITDA of $6.81B (+2%) and AFFO attributable to common stockholders of $4.93B (+7%), which is the key cash-flow metric for REIT distributions.
- Reported net income of $2.28B was boosted by a $730M lower D&A from extending tower useful lives to 30 years; the India sale produced a $1.2B loss within discontinued operations.
- Debt reduced to about $36.8B with $12.0B of liquidity; the January 2025 amendments extended the 2021 Multicurrency Credit Facility to 2028 and the 2021 Credit Facility to 2030.
- Churn was about 2% in 2024, primarily from U.S. & Canada, and is expected to remain elevated through 2025 due to T-Mobile lease cancellations and non-renewals (including legacy Sprint leases).
- Non-cancellable tenant lease backlog of nearly $54B, with 60% of revenue from four customers (T-Mobile 19%, AT&T 18%, Verizon 13%, Telefónica 10%), creating concentration risk.
- 2025 capex guided to $1.635-1.745B, with about 1,950-2,550 new communications sites and $610M of planned data center spend; distributions expected at $3.2B for 2025.

05—Questions
Frequently Asked Questions
How did American Tower perform financially in 2024, and what drove the reported net income increase?
Revenue grew 1% to $10.13B and Adjusted EBITDA grew 2% to $6.81B. Reported net income rose 67% to $2.28B, but much of that reflects non-operating and accounting items: a $730M reduction in depreciation and amortization from the tower useful-life change, a $378M other income gain (largely favorable FX and $70M of equity-security gains), and a lower goodwill impairment versus 2023. These were partly offset by the $978M loss from discontinued operations, mainly the $1.2B loss on the India sale. Investors typically focus on AFFO, which rose 7% to $4.93B.
What is the impact of the useful-life change on towers, and should investors treat it as recurring?
Management extended the estimated useful life of towers from 20 to 30 years, effective January 1, 2024. This lowered 2024 depreciation and amortization by about $730M ($649M after tax, or $1.39 per diluted share) and increased right-of-use assets and lease liabilities by about $515M. It is a one-time accounting estimate change that boosts GAAP earnings in the near term, but it does not change cash flows. Investors should adjust for it when comparing GAAP earnings with prior years.
What risks does the T-Mobile relationship pose?
T-Mobile is AMT's largest customer at 19% of 2024 revenue. Churn in the U.S. & Canada segment is expected to stay elevated through 2025 because of contractual lease cancellations and non-renewals under the September 2020 T-Mobile master lease agreement, including legacy Sprint leases. While the company says churn has not been materially adverse historically, the concentration means any further reduction in T-Mobile's footprint could meaningfully affect revenue growth and cash flow.
How strong is the balance sheet and what are the key debt maturities?
Total debt was about $36.8B at year-end 2024, with $3.7B current. Liquidity was $12.0B, including $10.0B available under credit facilities and $2.0B of cash. The company maintains investment-grade ratings and was in compliance with its bank covenants (total leverage of about 5.4x capacity headroom and senior secured leverage tests). Subsequent to year-end, it repaid $650M of 2.95% notes due 2025 and extended its bank facilities to 2028 and 2030. Investors should monitor the roughly $3.3B of 2026 maturities and the securitization DSCR tests, which can trap cash flow if coverage falls.
What are the main foreign exchange and international risks?
About 32% of 2024 revenue and 39% of operating expenses were denominated in foreign currencies, and AMT has historically not hedged most non-USD operations. The company recorded a $1.07B reclassification of cumulative translation losses on the India exit and large FX losses in OCI. A 10% adverse move in EUR debt would cause about $0.9B of foreign currency losses. Emerging-market exposure (Nigeria, Ghana, Brazil, Mexico) also brings regulatory, tax, and repatriation risks, and Nigeria and Ghana now use the U.S. dollar as functional currency under highly inflationary accounting.
