New Cingular Wireless PCS, LLC entered into an agreement to acquire Select Spectrum Assets from United States Cellular Corporation (NYSE:USM) for approximately $1 billion on November 6, 2024. Some of the licenses being sold to AT&T are owned by a third party.

The agreement with AT&T includes the sale of 1,250 million MHz-Pops of 3.45 GHz and 331 million MHz-Pops of 700 MHz B/C block licenses for a total of $1.018 billion. The consideration of approximately $1.018 billion payable in cash is subject to certain potential adjustments. Approximately $232 million of the AT&T Purchase Price has been allocated to certain Licenses in the 700 MHz band. Substantially all of the transaction is contingent upon the closing of the sale of the UScellular wireless operations and select spectrum assets to T-Mobile and is subject to the receipt of regulatory approvals, the expiration or termination of the waiting period under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended and satisfaction of customary closing conditions.
