SBA Communications, one of the largest owners of cell towers in the United States, reported second-quarter results that beat analyst forecasts and raised its 2026 revenue guidance by a small amount. The company said the improvement reflects continued spending by major wireless carriers—Verizon, AT&T, and T-Mobile—on upgrading their networks for 5G.
The news is a positive signal for the broader telecom infrastructure sector, which has seen uneven demand as carriers balance network investments with cost-cutting efforts. SBA's update suggests that, at least for now, the big carriers are still willing to write checks for tower space and equipment upgrades.
What SBA Communications does
SBA Communications is a real estate investment trust (REIT) that owns and operates wireless communications infrastructure. Its primary business is leasing space on its towers to wireless carriers and other tenants. The company earns recurring rental revenue, much like a landlord, and its financial health is closely tied to how much carriers are willing to spend on expanding and upgrading their networks.
As of June 30, SBA owned or operated 46,390 sites. The key growth driver right now is carriers adding new equipment to existing towers—a process known as colocation, where multiple tenants share the same structure. Colocations are more profitable than building new towers because they require less capital and generate additional rental income from the same asset.
The company's outlook for 2026 was nudged higher, reflecting management's confidence that carrier spending will remain steady through next year. This is a modest but notable upgrade, as many investors have worried that the pace of 5G buildout could slow after an initial wave of investment.
Why carrier spending matters
Verizon, AT&T, and T-Mobile are SBA's main customers. When these carriers upgrade a site—adding new antennas, radios, or other equipment—they typically sign new or extended leases with tower owners. That translates into higher rental revenue for SBA.
The carriers have been investing heavily in 5G, the latest generation of wireless technology, which promises faster speeds and lower latency. But 5G deployment is capital-intensive, and carriers have at times signaled they want to be more disciplined with spending. SBA's upbeat commentary suggests that, at least for now, the carriers are still prioritizing network quality and coverage.
This is consistent with broader trends in the telecom industry. While some companies have trimmed their outlooks due to economic uncertainty or supply chain issues, the demand for data continues to grow, and carriers need to keep upgrading their networks to stay competitive. For tower owners like SBA, that means a steady stream of leasing activity.
What it means for investors
For everyday investors, SBA's report is a reminder that the companies that own the physical infrastructure behind wireless networks can be a way to benefit from the ongoing 5G rollout without directly owning carrier stocks. Tower REITs like SBA, American Tower, and Crown Castle are often seen as relatively stable income investments because they generate predictable rental cash flows.
However, these stocks are also sensitive to interest rates. Because REITs pay out most of their earnings as dividends, they are often compared to bonds, and higher interest rates can make them less attractive. SBA's raised outlook is a positive fundamental signal, but the stock's performance will also depend on the broader rate environment.
Investors should also note that SBA's guidance is for 2026, which is more than a year away. The company is essentially saying it expects carrier spending to remain healthy through next year. That is a longer-term view, and it could change if the economy weakens or if carriers decide to cut back on capital expenditures.
For now, the message from SBA is that the 5G buildout is far from over. Carriers are still adding equipment to towers, and that is translating into higher revenue for the companies that own the towers. It's a steady, if not spectacular, growth story—one that could appeal to investors looking for income and moderate growth in the telecom space.
As always, it's worth keeping an eye on the broader market and the interest rate outlook. If rates stay elevated, tower stocks may face headwinds despite solid fundamentals. But SBA's latest numbers suggest the underlying business remains on solid footing.
