Overview

• Gopalan will take the top job on November 1, 2025, as Mike Sievert moves into a newly created vice chairman role advising on long‑term strategy, innovation and talent development.
• Gopalan became COO in March 2025 after nearly four years on T‑Mobile’s board and previously led Deutsche Telekom’s Germany business, with earlier senior roles at Bharti Airtel, Vodafone and Capital One.
• T‑Mobile says the new leader will help drive an initiative to become a more data‑driven, AI‑enabled, digital‑first company while reinforcing network investments in fiber and spectrum.
• Shares were little changed to slightly lower after the announcement, and analysts described the move as orderly succession while flagging execution challenges in a saturated U.S. wireless market and rising cable competition.
• The transition follows Sievert’s five‑year tenure integrating Sprint and expanding through deals such as Mint Mobile, Metronet, U.S. Cellular and Lumos, plus a Starlink tie‑up, during which T‑Mobile became the No. 2 U.S. carrier by subscribers.
