AT&T (T) has finalized a strategic sale-leaseback agreement with the private real estate development firm Reign Capital, involving the underutilized central office facilities. This transaction yields over $850 million in upfront cash proceeds for AT&T and involves the transfer of 74 properties. The company highlighted that this approach not only monetizes real estate assets in light of AT&T's plans to exit most of its legacy copper network operations by 2029, but it also aligns with its strategic capital allocation priorities.
