SBA Communications Corporation is an independent owner and operator of wireless communications infrastructure, structured as a real estate investment trust (REIT). The company primarily acquires, develops, and leases antenna space on multi-tenant towers to wireless service providers. Headquartered in Boca Raton, Florida, SBA operates a vast portfolio of nearly 40,000 communication sites across the Americas, Africa, and select Asian markets.
SBA depends on a small number of customers, with three nationwide wireless carriers each accounting for at least 10% of total revenues in fiscal 2025: T-Mobile (31.1%), AT&T Wireless (20.3%), and Verizon Wireless (15.1%).
