Senator Markwayne Mullin sold shares of T-Mobile US Inc (TMUS) valued between $50,000 and $100,000 on November 2, 2025. The transaction was reported on November 20, 2025, 18 days later, in compliance with the STOCK Act's 30-day reporting requirement.
This sale was made through a joint account. The STOCK Act of 2012 mandates that members of Congress report stock transactions to promote transparency and prevent insider trading. While such transactions are legal when disclosed, they should be considered as one of many data points by investors.
T-Mobile US Inc, headquartered in Bellevue, Washington, is a major player in the telecommunications industry, employing 70,000 full-time staff. The company provides wireless communications services under the T-Mobile and MetroPCS brands, utilizing its 4G LTE and 5G networks. T-Mobile's primary service plan, Go5G Plus, offers unlimited talk, text, and data, along with 5G access at no additional cost.
The company's market capitalization stands at $235.8 billion, with a price-to-earnings ratio of 19.87 and an earnings per share of 10.40. T-Mobile is set to announce its upcoming earnings on July 21, 2026, with an estimated EPS of $2.93 and revenue of $23.5 billion.
Such decisions reflect the financial activities of elected officials, and while research shows mixed results on the predictive value of congressional trading, they highlight the importance of transparency in government.
