T-Mobile

T-Mobile US Inc. is the second-largest US wireless carrier by subscriber count, listed on NASDAQ under TMUS and headquartered in Bellevue, Washington. Deutsche Telekom AG retains majority ownership of T-Mobile US through its approximately 51% equity stake, with the remaining float held across institutional and retail shareholders. CEO Mike Sievert has led the company since April 2020, succeeding John Legere whose decade-long tenure transformed T-Mobile from a distant fourth-place carrier into the “Un-carrier” challenger that fundamentally reshaped US wireless competition.

The 2020 merger with Sprint Corporation closed at a transaction value of approximately $26 billion, consolidating the US wireless market from four major carriers to three (T-Mobile, Verizon, and AT&T) and giving the combined T-Mobile a substantially expanded 5G spectrum portfolio anchored by Sprint’s 2.5 GHz mid-band holdings. T-Mobile reported total revenue of approximately $81.4 billion in fiscal year 2024, up 4% year-over-year, with the company’s continued postpaid net-add leadership driving market share gains against Verizon and AT&T. The product range covers wireless voice, data, and messaging services across consumer and business accounts, T-Mobile Home Internet (the company’s fixed-wireless-access broadband product launched 2021), Metro by T-Mobile (the prepaid value-segment banner), and the various enterprise-and-government wireless services. T-Mobile completed the acquisition of UScellular’s wireless operations announced in May 2024 and finalized through 2025, further expanding its network coverage particularly in rural markets. The Un-carrier brand-marketing platform launched in 2013 continues as the company’s defining commercial identity.

T-Mobile operates approximately 7,500 retail stores across the United States and Puerto Rico under the T-Mobile and Metro by T-Mobile banners, with the network combining company-operated and authorized-dealer locations. The typical T-Mobile store occupies 1,500 to 3,500 square feet, with formats integrating handset displays, plan-and-service consultation areas, accessory merchandising, and the company’s increasingly important in-store activation and customer-service operations. For mall operators, T-Mobile is a Class A and Class B+ specialty wireless tenant for regional and super-regional centers, typically positioned in the technology-and-electronics cluster alongside Apple, Verizon, AT&T, and Best Buy Mobile. The wireless carrier category has consolidated in mall positioning as carriers rationalized retail networks following the merger activity of recent years, with T-Mobile typically maintaining one primary location per regional center alongside Metro by T-Mobile presence in value-tier centers.
