American Tower Corporation

American Tower Corporation (AMT) is one of the largest global Real Estate Investment Trusts (REITs) and a leading independent owner, operator, and developer of multitenant communications real estate. Headquartered in Boston, Massachusetts, the company owns and operates a vast portfolio of more than 148,957 communications sites as of December 2024, including cell towers, distributed antenna systems (DAS), and data center facilities across the United States and internationally.

With a trailing 12-month revenue of $10.3 billion as of June 2025 and operations spanning six continents, American Tower serves wireless service providers and broadcasters by leasing space on its infrastructure. The company's portfolio includes 42,222 sites in the U.S. and Canada, 26,642 sites in Asia-Pacific and Africa, 31,786 sites in Europe, and 48,307 sites in Latin America. Additionally, through its CoreSite subsidiary acquired in 2021, American Tower operates a highly interconnected network of U.S. data center facilities.

Founded in 1995 as a unit of American Radio Systems, American Tower went public in 1998 and elected REIT status in 2012, a pivotal decision that transformed its business model. The company has grown through strategic acquisitions including Global Tower Partners ($4.8B, 2013), Verizon towers (11,448 sites, 2015), Telxius ($9.6B, 2021), and CoreSite ($10.4B, 2021). This aggressive M&A strategy has positioned AMT as a dominant player in wireless infrastructure.

As 5G networks expand globally and demand for AI-ready infrastructure accelerates, American Tower is well-positioned to benefit from increasing data consumption and network densification. The company's focus on high-quality assets in strategic locations, combined with long-term tenant contracts and built-in escalators, provides stable cash flows and attractive growth prospects for investors seeking exposure to the digital infrastructure megatrend.
