Who owns GoNetspeed and Greenlight Networks

GoNetspeed and Greenlight Networks - Profile

GoNetspeed and Greenlight Networks are two independent fibre to the home internet providers in the northeastern United States that are being combined inside a 50/50 joint venture formed by T-Mobile and the private equity firm Oak Hill Capital, announced in April 2026 and expected to close in the first half of 2027. Both companies design, build and operate their own fibre networks and sell symmetrical broadband of up to 8 Gbps to residential and business customers, and together they are described as the largest independent fibre providers in the Northeast. The combined footprint spans Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Pennsylvania and Rhode Island and is expected to pass more than 1.3 million homes by the end of 2026, with capacity sold wholesale to T-Mobile for its T-Fiber retail service.

The disclosed stakes

One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

• T-Mobile US, Inc., as of 25 Apr 2026. NOT YET CLOSED. On April 25, 2026, T-Mobile entered definitive agreements with affiliates of Oak Hill Capital Management, LLC to establish a joint venture that will acquire and combine GoNetspeed and Greenlight Networks, two of Oak Hill's existing fiber portfolio companies, into a single JV. Expected to close in the first half of 2027, subject to customary closing conditions and regulatory approvals, at which time T-Mobile expects to invest approximately $2.0 billion to acquire a 50% equity interest and substantially all existing residential fiber customers. Modelled/estimated because the transaction had not closed as of the Q2 2026 10-Q; the $2.0 billion is management's own stated expectation, not a completed investment. Confidence is 'contingent' rather than 'estimated': the brief reserves 'estimated' for a figure this research derived, which would carry low_shares, high_shares and the arithmetic, whereas this value is the transaction's own announced consideration and the stake itself does not exist until the deal closes. Same treatment as the Comcast NBCUniversal spin-off entities elsewhere in this database. source
