T-Mobile outlined two new transactions built around equal-share partnerships. In one deal, the company will work with Oak Hill Capital to acquire and combine GoNetspeed and Greenlight Networks. In the other, it will pair with Wren House to acquire i3 Broadband. The company said those agreements will expand its fiber footprint and extend internet service to more than 1 million additional homes nationwide.
The Oak Hill venture centers on two existing fiber operators that serve residential customers in several Northeastern states. T-Mobile said the combined GoNetspeed and Greenlight platform is expected to pass more than 1.3 million households by the end of 2026. Those markets include Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Pennsylvania and Rhode Island. In a separate Midwest-focused step, the i3 Broadband platform is expected to pass about 500,000 households by the end of 2026 across current markets in Missouri, Illinois and Rhode Island.
These deals fit into a broader broadband strategy that pairs T-Mobile’s 5G offering with a growing fiber business. The company said fixed wireless access has led industry growth for four straight years, while fiber has grown quickly as a complementary part of its portfolio. It added that wholesale partnerships and joint ventures have helped it reach about 1 million fiber customers in two years.
T-Mobile said fiber gives it another way to serve targeted markets by adding multi-gig speeds and extra capacity alongside its 5G service. The company also said these ventures combine its retail presence, brand and customer experience with the network-building capabilities of GoNetspeed, Greenlight and i3 Broadband, as well as the infrastructure investing experience of Oak Hill and Wren House. The businesses are expected to operate under wholesale models designed to scale efficiently.
The company said the Oak Hill transaction is expected to close in the first half of 2027, with an investment of about $2.0 billion for a 50% equity interest and substantially all existing residential fiber customers. The Wren House transaction is expected to close in the second half of 2026, with about $700 million committed on the same basis. T-Mobile said both deals remain subject to customary closing conditions and regulatory approvals, and that the added scale supports its path toward serving 18 million to 19 million total broadband customers by the end of 2030, including 3 million to 4 million fiber customers.
📊 What This Means (Our Analysis)
These transactions show how T-Mobile is building its broadband business with more than one tool. The company is not relying only on 5G growth; it is also using partnerships to add fiber capacity in defined markets, giving it a broader service mix and a wider geographic reach.
The structure matters, too. By using joint ventures and wholesale models, T-Mobile is expanding with established operators rather than starting from scratch, which gives the company a faster route to scale while supporting its long-term target for broadband and fiber customers.
📌 Our Take: These deals make fiber a larger part of T-Mobile’s national broadband equation.
