T‑Mobile Strengthens Next-Generation Broadband Portfolio with Two Strategic Fiber Partnerships

T-Mobile has entered into definitive agreements to form two strategic fiber joint ventures (JVs): a 50/50 partnership with Oak Hill Capital to acquire and combine GoNetspeed and Greenlight Networks, and a separate 50/50 joint venture with Wren House to acquire i3 Broadband. The transactions expand T-Mobile’s fiber footprint to bring fast, reliable internet to more than 1 million additional homes nationwide.

• JV with Oak Hill Capital for GoNetspeed & Greenlight Networks
  T-Mobile and Oak Hill, a private equity firm with deep digital infrastructure experience, have agreed to form a 50/50 JV through which T-Mobile will acquire a 50% stake in a joint venture integrating two of Oak Hill’s existing fiber portfolio companies, GoNetspeed and Greenlight. The businesses will expand T-Fiber by T-Mobile to residential customers across attractive markets primarily in the Northeastern U.S. with a current presence in states including Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, and Rhode Island. The combined platform is expected to pass over 1.3 million households by the end of 2026.

• JV with Wren House for i3 Broadband
  In a separate transaction, T-Mobile will form a 50/50 JV with global infrastructure investor Wren House to acquire i3 Broadband, a high-quality fiber-to-the-premises (FTTP) provider serving residential customers. The partnership brings i3 Broadband into T-Mobile’s growing fiber portfolio, adding another scalable FTTP platform backed by strong operational expertise and long-term infrastructure capital. i3 Broadband is expected to pass approximately 500 thousand households by the end of 2026, across current markets including those in Missouri, Illinois and Rhode Island.
