T-Mobile Surges 1.59% on $4.3B Array Deal Ranks 82nd in $990M Daily Volume Array Transforms to Tower Operator as Telecom Sector Restructures Asset Chains

T-Mobile US (TMUS) closed on August 11, 2025, with a 1.59% gain, trading at a daily volume of $0.99 billion, placing it 82nd in market activity. The move followed a strategic transaction that reshaped its competitive landscape.

Array Digital Infrastructure, formerly United States Cellular Corporation, finalized a $4.3 billion sale of its wireless operations to T-Mobile on August 1, 2025. This transaction marked a pivotal shift for Array, transitioning from a wireless carrier to a tower infrastructure provider. The deal included a $23-per-share special dividend to Array shareholders, reflecting the transaction’s value realization. Array’s CEO highlighted the strategic benefits, including access to 4,400 towers and a Master License Agreement with T-Mobile, positioning the company to expand colocation opportunities.

While Array’s Q2 earnings report showed a 1.2% decline in operating revenues year-over-year, the transaction’s completion signaled a structural repositioning. The company’s pending spectrum sales to AT&T and Verizon, expected in late 2025 and 2026, further underscore its evolving role in the telecom infrastructure sector. These developments indirectly support T-Mobile’s long-term asset optimization strategy, though Array has withheld 2025 financial guidance amid its transformation.

The strategy of purchasing the top 500 stocks by daily trading volume and holding them for one day delivered a 166.71% return from 2022 to the present, outperforming the benchmark return of 29.18% by 137.53%. This underscores the role of liquidity concentration in short-term stock performance, particularly in volatile markets.
