Forged Fiber 37 and Gigapower are soon to be the same joint venture.

When the sale was announced I thought if ATT couldn't find a different JV partner that the Lumen network would eventually be merged with the Blackrock JV Gigapower in some way.
ATT will own 50% of the new JV when it closes in the first half of 2027.
