AMT · Plain-English company overview
A stock is a share of ownership in a company. Owning one means you own a small piece of that business.
In the company's own words, from Item 1 (Business) of its latest annual report (Form 10-K) filed with the SEC on 2026-02-24.
We are one of the largest global real estate investment trusts and a leading independent owner, operator and developer of multitenant communications real estate. Our primary business is the leasing of space on communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in a number of other industries. We refer to this business, inclusive of our data center business discussed below, as our property operations, which accounted for 97% of our total revenues for the year ended December 31, 2025. We also offer tower-related services in the United States, which we refer to as our services operations. These services include site application, zoning and permitting, structural and mount analyses, and construction management services, together with program management offerings that support customer deployment needs from project scoping through construction. Our services operations primarily support our site leasing business, including the addition of new tenants and equipment on our sites. Our customers include our tenants, licensees and other payers.
Since inception, we have grown our communications real estate portfolio through acquisitions, long-term lease arrangements and site development. Our portfolio primarily consists of towers that we own and towers that we operate pursuant to long-term lease arrangements, as well as distributed antenna system (“DAS”) networks, which provide seamless coverage solutions in certain in-building and outdoor wireless environments. In addition to the communications sites in our portfolio, we manage rooftop and tower sites for property owners under various contractual arrangements. We also hold other telecommunications infrastructure, fiber and property interests that we lease primarily to communications service providers and third-party tower operators, and, as discussed further below, we hold a portfolio of highly interconnected data center facilities and related assets in the United States that we provide for the leasing of space primarily to enterprises, network operators, cloud providers and supporting service providers.
