Overview

• T-Mobile said COO Srini Gopalan will succeed Mike Sievert as chief executive on November 1, with Sievert moving to a newly created vice chairman role focused on long-term strategy, innovation, and talent.
• Gopalan became COO in March 2025 after nearly four years on T-Mobile’s board and previously led Deutsche Telekom’s Germany unit, where reports credit him with doubling growth and scaling its fiber business.
• The company framed the transition as planned succession and part of a strategy to become the industry’s most data-driven, AI-enabled, digital-first operator.
• Market reaction was muted, with one early report noting a near 1% premarket dip and later trading little changed, while analyst Craig Moffett said he expects no fall-off in performance.
• Gopalan told Reuters the focus turns to investing in spectrum and fiber as carriers face slower subscriber growth and tougher competition, with analysts also watching new cable wholesale arrangements that could reshape business wireless dynamics.
