Who Are the Core Customers in SBA Communications Company's Target Market?

T-Mobile, AT&T, and Verizon drive the core U.S. revenue mix and typically account for roughly 75 – 80% of domestic site leasing revenue; these wireless carriers require dense coverage and high-capacity sites for 5G rollouts, making them the highest-value SBA Communications customers.

Secondary tower tenants include Dish Network, municipal and federal agencies, enterprise private network customers, and smaller regional telecom operators; these telecom operators and 5G network providers add diversification and incremental tenancy on existing sites.

SBA Communications primarily serves businesses and institutions – mobile network operators, broadcasters, and broadband providers – acting as a wireless infrastructure provider that leases tower space and manages site operations for telecom companies expanding 5G coverage.

The U.S. Tier – 1 carriers are the most important segment by revenue and scale; international counterparts – Vivo and Claro in Brazil, Vodacom in South Africa – play the same strategic role abroad, anchoring multi – year contracts and supporting SBA Communications customers during capital investment cycles.

Demand concentrates in US suburban and per-urban corridors where mid-band C-Band and 2.5 GHz densification forces higher site counts; fixed wireless access (FWA) adoption is driving peak data loads and new colocations.

Brazil shows the fastest organic volumetric growth as 5G moves from megacities into secondary cities and regional networks, creating steady demand from major carriers that lease from SBA Communications and regional wireless carriers as SBA Communications customers.

SBA Communications is strongest on reach and revenue mix in the US and Brazil, with a large tenant base of wireless carriers and mobile network operators driving stable tenancy and high-margin site amendments; tower tenants and telecom operators boost recurring cash flow.

For 2025/2026 the biggest incremental growth is site amendments – existing tenants adding antennas and equipment – accounting for a disproportionate share of near-term revenue expansion and margin upside as 5G network providers and broadband providers lease extra capacity.

SBA Communications acquires new tenants by expanding into emerging markets like Tanzania and South Africa where 4G-to-5G migration creates fresh demand; it also targets regional wireless carriers, broadband providers, and enterprise private network customers to reach adjacent segments. Strategic site-build programs and site acquisition partnerships add capacity for international carriers and small cell providers.

High physical switching costs keep churn low – typically below 1.5 percent excluding carrier consolidations – since relocating equipment and re-permitting is disruptive and costly for mobile network operators. Fixed annual lease escalators in the US of 3 – 4 percent and inflation-linked adjustments abroad preserve revenue per tenant and make long-term contracts attractive to wireless carriers and telecom operators.

Repeat demand comes from assisting tenants with upgrades – zoning, permitting, structural engineering – and from multi-site deals with major carriers that lease from SBA Communications. This operational support increases ecosystem stickiness for tower tenants, IoT network operators, and 5G network providers, driving higher tenancy per site and renewal rates.

The key lever in 2025/2026 is geographic expansion into high-growth international markets plus contractual rent escalators: these together create a long runway for new tenant acquisition and ensure revenue growth outpaces operating expenses. For context, SBA Communications reported net lease revenues driving margin stability in 2025 while maintaining sub-1.5 percent churn among core tenants; see Competitive Landscape of SBA Communications Company for further detail: Competitive Landscape of SBA Communications Company
