Boston, Massachusetts-based American Tower Corporation (AMT) is a global real estate investment trust (REIT) that owns, operates, and develops wireless communications infrastructure, primarily cell towers, distributed antenna systems (DAS), and data-center assets. Mobile network operators lease space on its towers to host antennas and equipment needed for cellular voice and data transmission, typically under long-term, inflation-linked contracts that generate stable recurring rental revenue.
With a market cap of $85.4 billion, American Tower clearly qualifies as a “large-cap” company, as firms valued above $10 billion are generally classified in this category. Its market leadership stems from its global scale, strategic tower locations, deep carrier relationships, and structural demand growth from rising mobile data usage, 5G densification, and network coverage expansion.
