American Tower AMT

Real EstateMarket cap $79B5 connections

American Tower owns 220,000+ wireless towers globally - the steel structures that every cell carrier must lease to reach customers. 5G requires 3-5x more tower sites than 4G - every network upgrade drives tower lease renewals at higher rates. Its international towers (India, Africa, Europe) are its fastest-growing segment as 4G and 5G penetrate emerging markets. Tower leases escalate 3% annually in perpetuity.
