- Current COO Srini Gopalan succeeds Mike Sievert as CEO
- Sievert moves to Vice Chair role, remains on Board
What happened: Succession plan at T-Mobile confirmed by Board and leadership
T-Mobile announced that Srini Gopalan, currently Chief Operating Officer, will become Chief Executive Officer effective 1 November 2025. He will succeed Mike Sievert, who has led T-Mobile through several years of growth under its “Un-carrier” strategy. Sievert will transition to Vice Chairman of the company and Board. In that position, he will continue advising on long-term strategy, innovation, talent development and external relations.
The Board described this move as part of a well-established succession planning process. Gopalan joined T-Mobile as COO following a tenure as CEO in Germany, where he delivered growth in fibre deployment, mobile market share and satisfaction metrics. He has led T-Mobile’s operations, technology, consumer and business units. Under his leadership the company completed multiple acquisitions and expanded 5G and broadband reach.

Why it’s important
This change is significant for several reasons. First, it demonstrates strong governance at T-Mobile by executing a planned leadership transition rather than a sudden change. Gopalan’s previous experience leading large technical and commercial teams gives reassurance to investors and regulatory bodies that he can continue T-Mobile’s performance and strategy. His track record in Germany includes scaling fibre infrastructure and improving customer satisfaction scores, which aligns with global standards for network quality and operator reliability.
Second, continuity in leadership supports ongoing initiatives in 5G, broadband expansion, and customer experience. Gopalan has been deeply involved in those programs as COO. His promotion helps maintain internal alignment around strategy execution. For customers and competitors, this move confirms that T-Mobile intends to double down on value, innovation and digital transformation. Confidence in management stability often plays a role in regulatory oversight, spectrum licensing, and capital investment decisions in telecoms.
