How American Tower Makes Money
American Tower earns recurring revenue by leasing vertical space, ground space, power, cooling, and related infrastructure to wireless carriers, broadcasters, governments, and cloud or data-center customers. Its tower leases tend to be long-term contracts with high switching costs because moving antennas can disrupt network coverage.
The CoreSite data-center business adds colocation and interconnection exposure, giving American Tower a second infrastructure platform tied to cloud, enterprise, and network connectivity demand.
American Tower Origin Story
The company began as American Tower Systems inside American Radio Systems. Steven B. Dodge and the ARS team recognized that towers used for broadcasting could become a dedicated wireless infrastructure business as carriers needed more leased antenna space.
FY2025 Strategic Context
The FY2025 profile reflects portfolio reshaping, including the India divestiture, plus continued focus on high-quality towers, disciplined capital allocation, and CoreSite data centers. CEO Steven Vondran leads the company through the next phase of mobile data, cloud connectivity, and edge infrastructure demand.
