Based on the last 12 months of reports, through 31 March 2026
The sector median covers every company in the sector on the US market, loss-making ones included.
American Tower owns mobile towers and leases them to carriers — one tower holds several tenants.
Tower economics are simple and very favourable: building and maintaining one costs the same regardless of tenant count, and each additional carrier pays nearly pure profit. The key metric is therefore not tower count but average tenants per tower.
Leases run for years with automatic escalators, and a carrier cannot terminate without losing coverage. That makes cash flow exceptionally predictable — which is why the company is structured as a property trust and distributes nearly all profit.
The weak point is debt and rates: building and buying towers was financed with cheap money, and dearer credit weighs directly on profit and valuation. The second factor is carrier consolidation: merging two tenants means giving up duplicate sites. The company pays a growing dividend.
