Revenue Model & Pricing
American Tower owns the tower structure and controls the land beneath it, then leases vertical space to mobile operators such as T-Mobile, AT&T and Verizon so they can mount antennas. The economics turn on colocation: once a tower stands, adding a second or third tenant costs comparatively little, so incremental rent converts largely into operating profit. In FY2025, property revenue of $10,305 million made up 97% of the $10,645 million total, with CoreSite data centers contributing $1,053 million of that and services and other work adding $340 million.

Growth Strategy
After selling its India business in 2024, American Tower concentrates capital on developed markets and on data centers. About 85% of planned 2026 discretionary capital spending goes to developed markets, including more than $700 million for CoreSite data center development, where revenue grew about 14% in 2025. Outside the United States, growth now comes from Africa, Asia-Pacific and Europe: Africa and Asia-Pacific property revenue rose 17.8% in 2025 and Europe rose 12.3%. At home the emphasis is adding tenants and equipment to existing towers rather than building large numbers of new sites, since US and Canada property revenue was flat in 2025.
How American Tower Makes Money: FAQ
How does American Tower generate revenue across its global infrastructure?
American Tower generates revenue primarily through long-term, non-cancellable real estate site leases with wireless service providers, power and fuel pass-through fees in developing markets, and interconnection and colocation fees via CoreSite data centers.
What are the typical lease terms for American Tower's telecom leases?
Lease contracts typically run for initial non-cancellable terms of 5 to 10 years with multiple 5-year renewal periods, featuring contractual annual rent escalators (around 3% in the U.S. and linked to local CPI internationally).
How does the multitenant tower business model drive operating leverage?
Adding a second or third carrier tenant to an existing macro tower incurs minimal capital expenditure, allowing gross operating margins on individual towers to expand from approximately 40% with one tenant to over 80% with three tenants.
What is American Tower's Master Lease Agreement (MLA) structure with major carriers?
Holistic Master Lease Agreements (such as long-term MLAs with T-Mobile and AT&T) provide carriers with predictable recurring pricing and streamlined equipment deployment rights across thousands of tower sites simultaneously.
How does CoreSite monetize interconnection and colocation services?
CoreSite charges enterprise, cloud, and network customers monthly recurring fees for cabinet and cage space, power consumption, and direct cross-connect cabling linking into hyperscale cloud on-ramps.
What is American Tower's land ownership strategy under its towers?
American Tower secures long-term land control under its towers through fee-simple land purchases or multi-decade ground leases, ensuring that over 90% of gross property margin is protected on land with at least 20 years of remaining control.
How does American Tower monetize distributed antenna systems (DAS) and small cells?
In dense urban centers, stadiums, and tunnels where macro towers cannot be built, American Tower deploys shared indoor/outdoor DAS and micro-towers, leasing access to multiple mobile operators over unified fiber feeds.
