Crown Castle maintains a dominant U.S. focus with significant investments in fiber and small cell technology.

Which tower infrastructure giant is the better fit for your portfolio in 2026?

The build-out of 5G networks remains a massive multiyear tailwind for the real estate sector. Choosing between SBA Communications (NASDAQ:SBAC) and Crown Castle (NYSE:CCI) requires weighing international growth against domestic fiber strength.

Both companies operate as real estate investment trusts (REITs), owning the essential infrastructure that allows your smartphone to function. While they share similar business models, their geographic focuses and asset mixes differ significantly. One prioritizes global expansion while the other bets heavily on U.S. small cells and fiber to complement its traditional tower portfolio.

SBA Communications provides essential infrastructure by leasing tower space to wireless providers. Its primary customers include T-Mobile , AT&T , and Verizon . T-Mobile alone accounted for more than 31% of total revenue in 2024, and customer concentration like this adds a layer of risk to the business.

In FY 2025, revenue reached nearly $2.8 billion, which was a growth rate of approximately 5.1% from the previous year. The company reported net income of roughly $1.1 billion during this period. This led to a net margin of approximately 37.4%, which measures how much of each dollar earned becomes profit.

As of its December 2025 balance sheet, the debt-to-equity ratio was -3.2x, indicating that total liabilities exceed shareholder equity. The current ratio, which compares short-term assets to short-term liabilities, was roughly 0.5x. For the year, the company generated free cash flow of close to $1.1 billion.
