SBA Communications Corporation (SBAC) — Business Overview
Business Description
SBA Communications is a leading independent owner and operator of wireless communications tower infrastructure, structured as a REIT. Founded in 1989 and headquartered in Boca Raton, Florida, the company leases space on its 46,328 towers to wireless carriers under long-term contracts with annual rent escalators. Approximately 97.9% of segment operating profit comes from site leasing — making SBAC one of the purest tower infrastructure plays in the market. The company operates primarily in the U.S. (72.6% of site leasing revenue) and select international markets, having recently exited Canada, Philippines, and Colombia to focus capital on higher-growth regions.
Revenue Model
SBA Communications generates revenue almost entirely from multi-tenant tower leases. Carriers pay recurring monthly rents to co-locate antennas and related equipment on SBA's tower structures. Lease terms typically run 5–10 years with 3–4% annual rent escalators, creating highly predictable, inflation-linked cash flow streams. A second, smaller segment — Site Development — provides network build-out services (site acquisition, zoning, construction) to carriers building new towers, generating modest project-based revenue (~2% of operating profit). Tower leases are essentially fixed-cost infrastructure with incremental margins above 90% when additional tenants are added.
Products & Services
Site Leasing (~98% of operating profit):
- Multi-tenant tower leasing (macro towers, rooftop installations)
- Distributed Antenna Systems (DAS) and small cells
- Long-term lease agreements with built-in CPI or fixed annual escalators
- New tower builds for carrier customers (build-to-suit)
Site Development (~2% of operating profit):
- Site acquisition and zoning services
- Tower construction and equipment installation
- Network build-out project management for MNOs
Customer Base & Go-to-Market
SBA Communications' three largest customers — T-Mobile, AT&T, and Verizon — accounted for 66.5% of total revenues in 2025 (T-Mobile alone ~35%). Revenue concentration among the major U.S. carriers creates both durable relationships and meaningful tenant risk. International exposure (~27% of revenue) spans Brazil, Central America (expanded through the 7,000-tower Millicom/TIGO acquisition), and other Latin American markets. Customer churn is primarily driven by carrier M&A (Sprint/T-Mobile consolidation) and financial distress (EchoStar/DISH default).
Competitive Position
SBAC is the third-largest U.S. tower REIT behind American Tower and Crown Castle, competing in a rational oligopoly where infrastructure sharing reduces carrier costs and creates high barriers to entry. Tower building requires years of permitting, community negotiation, and significant upfront capital — giving existing owners a structural moat. With 80% Tower Cash Flow margins and escalating rents, SBA generates superior cash yields on invested capital. The company has been the most aggressive in international expansion among the big three, with ~27% of revenue from international markets (vs. AMT's ~50% and CCI's ~0%).

Growth Profile
SBA Communications' revenue declined modestly in FY2024 due to elevated carrier churn — primarily Sprint/T-Mobile consolidation ($51M in 2025 churn) and EchoStar/DISH network default ($56M annual churn impact). Beneath the headline, organic leasing activity remains healthy: new leases and amendments added tenants at 3–4% organic growth rates, partially offset by the above churn. AFFO per share still grew 2.2% in FY2024, demonstrating the cash generation resilience of the business model even through headwinds. Once churn normalizes (expected "significant step down" by 2026), organic growth should accelerate to 4–6%.
Forward Estimates
- FY2025 Revenue: ~$2.8B (Millicom/TIGO acquisition adds tower count; core revenue recovers)
- Q1 2026 Revenue: $703.4M (up YoY despite ongoing churn headwinds)
- Management FY2026 Churn Guide: $36–40M international + $56M EchoStar + ~$75M Sprint/T-Mo cumulative
- Target investment-grade credit by FY2026, enabling dividend growth and lower cost of capital
