Shares of Array Digital Infrastructure Inc. (USM), formerly known as United States Cellular, are soaring 5.72% in pre-market trading on Monday following the release of its second-quarter 2025 results. The company reported better-than-expected earnings and revenue, while also announcing the completion of a significant asset sale.

Array Digital Infrastructure posted a diluted earnings per share (EPS) of $0.36 for Q2, significantly surpassing the analyst consensus estimate of $0.30. This represents an 80% increase from $0.20 per share in the same period last year. The company's total operating revenue came in at $916 million, slightly beating the expected $907.6 million, despite a 1.19% year-over-year decrease.

Investors are particularly encouraged by the company's strategic moves, including the completion of a $4.3 billion sale of its wireless operations and select spectrum assets to T-Mobile. This transaction is expected to strengthen Array's position as a tower company, with 4,400 towers and a new Master License Agreement with T-Mobile. The company anticipates growth opportunities in colocations, revenues, and margin expansion. Additionally, Array has pending spectrum transactions with AT&T and Verizon, expected to close in the second half of 2025 and Q3 2026, respectively. While the company is not providing financial guidance for 2025, these strategic initiatives seem to be driving investor optimism about Array's future prospects in the tower business.
