## About

Originally a unit of American Radio Systems, American Tower was spun out in 1995 and became a public REIT in 1998. Steve Vondran took over as CEO in 2024, succeeding long-time chief Tom Bartlett, who oversaw a decade of aggressive international expansion. The firm is headquartered in Boston, Massachusetts. American Tower leases space on its tower, rooftop, and small-cell sites to tenants including AT&T, T-Mobile, and América Móvil. The business model works on multi-year contracts with fixed rent escalators, which produces visible, CPI-linked cash flows. Asset classes span macro towers, distributed antenna systems (DAS), and edge data centers. The portfolio leans heavily into North America and Latin America, but the firm has a substantial African presence through its ATC Africa operation and a large Indian footprint via ATC India. In 2023, the company completed the sale of its Polish business and exited a challenged receivable position in India by selling its stake in ATC India to Brookfield for approximately $2.5 billion. With a total enterprise value consistently above $100 billion, American Tower ranks among the largest publicly traded REITs globally. The company operates through a series of local joint ventures and wholly owned subsidiaries rather than external co-investor club structures. Its most notable adjacent vehicle is CoreSite, a data-center and interconnection business acquired in 2021 for roughly $10.1 billion, which adds a hybrid IT layer directly tied to its tower fiber backhaul network. In March 2024, the company promoted Steven Vondran to CEO after his tenure leading the U.S. tower division. Structurally, American Tower is a pure-play tower REIT positioned at the intersection of real estate and telecom infrastructure, with its moat defined by extreme zoning scarcity and low turnover costs. Unlike diversified infrastructure funds, it commits almost entirely to a single vertical, creating operational depth rather than cross-sector balance. Governance is standard public REIT with a board of directors and no controlling family or founder.

## Questions

### How is American Tower related to CoreSite?

American Tower acquired CoreSite for approximately $10.1 billion in December 2021. CoreSite operates carrier-neutral data centers and cloud interconnection facilities in major U.S. markets, and its assets complement American Tower's dense metro fiber and small-cell infrastructure.

### Which markets does American Tower explicitly avoid?

The company has exited or materially reduced exposure in regions where counterparty risk became unmanageable. It sold its Indian subsidiary to Brookfield in 2023 after sustained receivable challenges with Vodafone Idea and divested its Polish business the same year, signaling a preference for markets with stable tenant credit profiles.
