SBA Communications has sold its tower assets in Chile and Ecuador.

The company announced the sales during its Q3 earnings report, while also noting that it has reached an agreement to sell all of its towers and related assets held in Peru. SBA's sale in Peru remains subject to regulatory approvals.

Financial terms of SBA's exit from Chile and Ecuador were not disclosed, but the company did note that it has impacted the company's 2026 full-year outlook by approximately $10 million for site leasing revenue, plus $6m for tower cash flow, and $4m for adjusted EBITDA.

It follows on from the company's exit from Colombia last year, as SBA ramps up its move to exit most South American markets, with the exception of Brazil.

"Internationally, we continued to sharpen our focus, agreeing to sell our towers in three South American markets, completing our exit from the region outside of Brazil, while more than doubling our new tower builds in the markets where we have scale," said Brendan Cavanagh, president and CEO of SBA Communications.

For the quarter itself, SBA Communications reported site rental revenues of $665.4 million, which was an increase of 1.4 percent year-on-year (YoY).

“Demand for our tower assets remains strong as wireless carriers continue to expand and upgrade their networks,” said Cavanagh. “Mobile data traffic continues to grow, and meeting that demand requires more equipment on more towers."

The company is bullish on future spectrum auction opportunities in the US, where it operates more than 17,000 tower sites. The FCC is set to auction spectrum in the upper C-Band next year.

"Looking ahead, we are excited about the next wave of network investment. The upper C-band auction, a growing pipeline of new spectrum, and the industry’s move toward 6G is expected to drive new deployments on our sites, and we are seeing new opportunities from satellite and Edge compute providers that value the reach and infrastructure of our portfolio."

SBA continues to Edge its bets

The company's mention of Edge is pretty significant, given SBA has been exploring how its tower infrastructure can support Edge compute deployments.

In July, SBA launched an Edge data center site in Corpus Christi, Texas, and Cavanagh said the company will continue to push its Edge strategy at its tower sites in the US, where he anticipates the ability to bring compute.

"Through our SBA Edge entity, we offer access to the power and infrastructure needed so that AI customers can deploy quickly and efficiently. We have several Edge sites up and running with a handful of different companies building out distributed AI inference capacity," said Cavanagh during SBA's earnings call.

"So far, the incremental capital remains minimal as these Edge deployments use vacant space and excess power at our tower."

The company began exploring Edge computing modules at tower sites in 2018 in partnership with Packet before its acquisition by Equinix.

One of the first places the companies trialed an at-tower deployment was Foxborough, Massachusetts. The firm has also deployed one in Arlington, Texas.

Jared Benson, director of strategic Edge infrastructure at SBA, said the company is working on a second Edge site in Arlington and has one deployed near Jacksonville, Florida.
