Array Digital Infrastructure, formerly UScellular, has completed the sale of $1.08 billion worth of spectrum to AT&T.

The sale, first announced in November 2024, was finalized earlier this week.

Approval of the deal follows the Federal Communications Commission (FCC) giving its blessing to the deal last month after AT&T agreed to ditch its DEI-related policies.

As part of the agreement, AT&T snaps up 1,250 million MHz-Pops of 3.45 GHz and 331 million MHz-Pops of 700 MHz B/C block licenses.

The FCC said that the deal will enable AT&T to enhance its network coverage, capacity, and performance.

Array noted that following the close of the sale, its board of directors has declared a special cash dividend of $10.25 per common share and Series A common share. The special dividend is payable on February 2, 2026, to shareholders of record on January 23, 2026.

"We are pleased with the significant value realized in this sale," said Anthony Carlson, president and CEO, Array Digital Infrastructure. "And we are continuing to return value to our shareholders in the form of a special dividend."

UScellular was previously a regional wireless player, but sold its wireless operations, which included the company's 4.5 million customers, to T-Mobile for $4.4bn in August.

As part of that deal, T-Mobile has acquired UScellular's operations, including its customer base and around 30 percent of the company's wireless spectrum. The telco separately struck a separate spectrum sale deal with Verizon for $1bn.

UScellular has instead pivoted its T-Mobile sale to become a tower infrastructure-focused business and has rebranded as Array Digital Infrastructure.
