## Summary

SBA Communications (SBAC) reported ~$2.3B revenue in FY2024. Independent wireless tower REIT owning 39,000+ cell towers in the Americas and South Africa. HQ: Boca Raton, FL.

## Company Overview

SBA Communications Corporation is a leading independent owner and operator of wireless communications infrastructure, primarily cell towers, in North America, Latin America, and South Africa. Founded in 1989 and structured as a real estate investment trust (REIT), SBA owns approximately 39,000 tower sites that it leases to wireless carriers including AT&T, T-Mobile, Verizon, and regional operators who install antennas to provide mobile coverage to their subscribers.

SBA reported approximately $2.3 billion in revenue in FY2024, with the tower business generating highly predictable, contracted cash flows. Tower REITs benefit from long-term leases (typically 5–10 years with automatic rent escalators of 3%) and high incremental margins — adding a new tenant to an existing tower requires minimal capital and flows almost entirely to profit. SBA has approximately 1.7 tenants per tower on average, with meaningful upside as 5G buildouts drive carriers to add equipment to existing sites rather than build new towers.

SBA differentiates through its international exposure — roughly 40% of sites are in Brazil and other Latin American markets where wireless infrastructure is less mature and organic growth is higher. The company has been actively managing its balance sheet after a period of significant leverage from international acquisitions, prioritizing debt reduction and share buybacks. Long-term, 5G densification, small cell deployment, and emerging market wireless penetration represent compelling secular growth drivers for tower infrastructure.

## Frequently Asked Questions

### What does SBA Communications do?
SBA Communications owns approximately 39,000 cell towers that it leases to wireless carriers (AT&T, T-Mobile, Verizon) who install antennas to provide mobile coverage. It earns recurring lease revenue with built-in escalators.

### How do cell tower companies make money?
Tower companies like SBA lease vertical space on their towers to multiple wireless carriers. Each additional tenant on a tower requires minimal cost but generates significant incremental revenue — creating very high margins as towers get more tenants.

### What is SBA Communications' ticker?
SBA Communications trades on the Nasdaq under the ticker SBAC. It is structured as a REIT and is a component of the S&P 500.

### What is the growth opportunity for SBA?
5G network densification requires carriers to add more equipment to existing towers (increasing revenue per tower) and build new sites. SBA also benefits from continued wireless penetration growth in Latin America, where mobile infrastructure is less mature.

### What is SBA Communications and what assets does it own?
SBA Communications is a publicly traded cell tower REIT and one of the largest independent owners and operators of wireless communications infrastructure in the Americas. Its portfolio includes tens of thousands of cell towers across the US, Latin America, Canada, South Africa, and other markets.

### How does SBA Communications generate revenue?
SBA generates revenue by leasing antenna space on its towers to wireless carriers like AT&T, Verizon, T-Mobile, and regional operators. Each tower can host multiple tenants, and SBA earns recurring rental income under long-term lease agreements that typically include annual escalator clauses.

### What drives demand for SBA Communications' tower assets?
Demand is driven by wireless carriers' ongoing need to expand and densify their networks to handle growing mobile data traffic from smartphones and connected devices. The deployment of 5G networks requires significant additional tower infrastructure, creating a multi-year demand tailwind for tower owners.

### How does SBA Communications differ from American Tower and Crown Castle?
While all three are major tower REITs, SBA Communications has a heavier concentration of international assets relative to peers, particularly in Latin America. SBA has also historically been more focused on towers rather than small cells or fiber, though the company continues to evaluate its portfolio strategy as network infrastructure needs evolve.
