SBA COMMUNICATIONS CORP (SBAC)

SBA Communications is a leading independent owner and operator of wireless communications infrastructure, primarily towers, rooftops, and other structures that support antennas, operating principally in the United States and its territories as well as in South America, Central America, Canada, South Africa, the Philippines, and Tanzania. Its core business is site leasing, which contributed 97.4% of total segment operating profit in 2023, comprising domestic and international reportable segments; the company leases antenna space on its multi-tenant towers to wireless service providers through individual site leases or master lease agreements, and also manages rooftop and tower sites for property owners. As of December 31, 2023, it owned 39,618 towers globally—17,487 domestic sites (73.4% of total site leasing revenue, with major customers including T-Mobile, AT&T Wireless, Verizon Wireless, and DISH Wireless) and 22,131 international sites across 14 countries (with Brazil representing about 30% of total towers)—averaging 1.9 tenants per tower.

Its secondary business line is site development, assisting wireless carriers in building and maintaining their own networks, though this contributes a smaller, more cyclical share of profit. Strategically, the company focuses on maximizing tower capacity, leveraging its scale and long operating history (developing towers since 1989 and owning/operating them since 1997), growing its portfolio through disciplined acquisitions and new tower construction (including build-to-suit arrangements), expanding selectively into international markets with favorable economic and regulatory conditions, controlling underlying land positions through easements and long-term leases (with about 71% of towers on land controlled for over 20 years), and exploring ancillary and emerging opportunities such as edge data centers, open-access networks, data offloading, and energy-as-a-service solutions including battery backup and solar systems. Revenue drivers include rising mobile data consumption, spectrum auctions, and continued 5G deployment by carriers, with lease terms typically spanning five to fifteen years featuring fixed or inflation-linked rent escalators, and international leases often denominated in a mix of U.S. dollars and local currencies depending on the market.
