T-Mobile CEO Mike Sievert is Stepping Down in 2025
T-Mobile has made a significant leadership change. CEO Mike Sievert will be stepping down in early 2025. Sievert has successfully led the company through its major merger with Sprint and established its dominance in the 5G era. Mike Katz, the company’s current President of Marketing, Strategy, and Products, will succeed Sievert. Katz will bring stability and experience to guide T-Mobile into its next chapter.
A Transformative Tenure: The Legacy of Mike Sievert
Mike Sievert took over as CEO in April 2020, a pivotal moment for T-Mobile. He inherited the immense responsibility of merging Sprint, marking one of the largest mergers in telecommunications history. Despite facing numerous challenges, his tenure will primarily be remembered for solidifying T-Mobile’s position as a formidable competitor to AT&T and Verizon.
The Highs: Sprint Merger and 5G Dominance
Sievert’s crowning achievement was the seamless execution of the $26 billion Sprint merger. Under his leadership, T-Mobile rapidly combined disparate networks and retail operations, a process many industry analysts predicted would be fraught with difficulty. The result was the creation of the nation’s leading 5G network.
According to data from firms like Ookla and Opensignal, T-Mobile has consistently ranked first in 5G speed and availability in the U.S. for several years. This network superiority allowed the company to attract millions of new subscribers. During Sievert’s tenure, T-Mobile’s stock (TMUS) saw significant growth, reflecting investor confidence in his strategy.

The Lows: Data Breaches and Layoffs
Sievert’s leadership was not without its trials. The company suffered from several high-profile data breaches, which exposed the personal information of tens of millions of customers and damaged the brand’s reputation for trust. These incidents led to significant regulatory fines and mandated security overhauls.
Furthermore, in 2023, Sievert announced a plan to lay off approximately 5,000 employees, or about 7% of the company’s workforce. The move was framed as a necessary step to reduce redundancies post-merger but was met with criticism from labor advocates.
Meet the New Leader: Who is Mike Katz?
The appointment of Mike Katz as the next CEO signals a focus on continuity and brand strength. Katz is a T-Mobile veteran, having been with the company for over 25 years. He is widely regarded as one of the key architects of the ‘Un-carrier’ brand identity, the disruptive marketing strategy that transformed T-Mobile from a distant fourth-place carrier into a market leader.
As Chief Marketing Officer, Katz was instrumental in crafting the campaigns that attacked industry pain points like long-term contracts, overage fees, and international roaming charges. His deep understanding of the T-Mobile brand and its customer-centric ethos makes him a natural successor to Sievert.
In an interview with Reuters, telecom analyst Roger Entner commented, “Katz is T-Mobile’s DNA. He understands the ‘Un-carrier’ philosophy better than anyone. This is the safest and smartest choice they could have made.”
The Future of the ‘Un-carrier’: Challenges Facing T-Mobile
Mike Katz will inherit a company in a strong market position but facing a new set of challenges. With the 5G network build-out largely complete, the next phase of growth is less certain. Key challenges include:
- Intensifying Competition: AT&T and Verizon have ramped up their promotional activity, and cable companies like Comcast and Charter are becoming more aggressive in the mobile space.
- Growth Beyond Mobile: T-Mobile has invested heavily in new areas like 5G home internet. Sustaining momentum in these new markets will be crucial for continued growth.
- Rebuilding Customer Trust: Addressing the reputational damage from past data breaches and preventing future incidents must be a top priority.
- Maintaining Brand Identity: As T-Mobile has grown into an industry giant, a key challenge for Katz will be to maintain the agile, disruptive ‘Un-carrier’ spirit that defined its rise. For more analysis on the telecom industry, see reporting from the Financial Times.
