T-Mobile US COO Sells Portion of 580 Billion Won Stake

T-Mobile US, Inc. (NASDAQ: TMUS) disclosed that on May 21, 2026, Chief Operating Officer John Pryor sold approximately 4,800 shares of the company’s common stock at roughly $190 per share under a pre-established Rule 10b5-1 trading plan, generating about $910,000 (approximately KRW 1.3 billion) in proceeds. Following this sale, Pryor still holds around 217,000 shares—worth about $41.3 million (roughly KRW 58 billion) at current market prices—including shares acquired through the employee stock purchase plan.

On June 16, outside directors Raúl Marcelo Clare and Srikant M. Datar were each granted approximately 1,384 restricted stock units (RSUs) under the company’s 2023 Incentive Plan. Director Datar also restructured his indirect holdings by transferring a portion of the shares he and his spouse held jointly into a personal investment vehicle.

Separately, T-Mobile US has been raising certain regulatory fees and ancillary service charges over the past few months. Effective June 25, the carrier will double its per-minute international calling rate for U.S. customers from $0.25 to $0.50. On June 10, the company announced the nationwide rollout of its AI-driven “Dynamic CX” technology, which automatically reallocates 5G network capacity in advance by predicting data-traffic congestion during major events such as the 2026 FIFA World Cup.

Headquartered in Bellevue, Washington, T-Mobile US is the third-largest wireless carrier in the United States, with Germany’s Deutsche Telekom holding about a 54 percent stake. Since its 2020 merger with Sprint, the company has broadened its offerings to include 5G mobile services, home internet and fiber-broadband, thereby diversifying both its subscriber base and revenue streams.
