American Tower Corporation's Growth & Acquisition 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 Corporation Makes Money

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.
