In a significant move to bolster its wireless operations, T-Mobile US, Inc. (TMUS) has completed its acquisition of U.S. Cellular, renaming the entity to Array Digital Infrastructure, Inc. The transaction, valued at $4.4 billion, was finalized on August 1, 2025, following regulatory approvals [1].

Under the terms of the agreement, T-Mobile acquired U.S. Cellular's wireless operations and approximately 30% of its spectrum assets. The remaining spectrum and towers will be retained by U.S. Cellular, which will now operate as a tower company known as Array Digital Infrastructure [2]. The acquisition will add around 4.4 million customers to T-Mobile's customer base, enhancing its market position [1].

Douglas W. Chambers, the current CFO of U.S. Cellular, will serve as the interim President and CEO of Array Digital Infrastructure, overseeing a portfolio of 4,400 towers and some spectrum assets [3]. The transaction was led by Citigroup Global Markets Inc. as the lead financial advisor, with Centerview Partners LLC and PJT Partners LP also playing key roles [2].

The acquisition is expected to have a positive impact on T-Mobile's financials, with the company assuming up to $2 billion in debt from U.S. Cellular. The transaction is also subject to certain financial and operational metrics that could further adjust the purchase price [2]. T-Mobile anticipates that the integration of U.S. Cellular's assets will enhance its network coverage and capacity, particularly in rural areas where U.S. Cellular has a strong presence [1].

Bloomberg financial analysts have noted that the acquisition aligns with T-Mobile's strategy to expand its network and compete more effectively in the wireless market. The renaming of U.S. Cellular to Array Digital Infrastructure reflects the company's new focus on providing infrastructure services to other wireless carriers [3].
