The Director Who Crossed the Table

On January 27, 2025, T-Mobile US told the market that one of its own directors would stop supervising management and join it. Srinivasan Gopalan had sat on the board since 2022. On March 1 he would become chief operating officer, reporting to chief executive Mike Sievert, with the Consumer, Business and Technology groups all reporting to him.

The brief he described for himself was plumbing. Transformation across Consumer and Business. The orchestration of technology delivery. "This is an important time for the company, the most exciting chapter yet" was as far as he went.

Eight months later the board gave him the company.

The Succession He Walked Into

On September 22, 2025, T-Mobile named Gopalan chief executive effective November 1. Sievert did not leave. He was appointed Vice Chairman, a newly created management position, and stayed on the board and the management team, advising on strategy, innovation, talent development and external relations.

Read that announcement for what it loaded onto the incoming man. It recorded that T-Mobile had added more than $200 billion in market capitalisation under Sievert, and described his tenure, in the company's own words, as the most value-creating in global telecom history. The person inheriting that scoreboard was 55 years old and had been a T-Mobile employee for less than eight months.

Gopalan's reply was deference first. "I am honored and grateful for the trust Mike and the Board have placed in me," he said. Then came the sentence he would spend the next year trying to make arithmetic out of: "Customers no longer need to make tradeoffs".

The Record Came From Germany

Everything he brought was built somewhere else. From January 2017 to October 2020 Gopalan sat on Deutsche Telekom's Board of Management with responsibility for the Europe segment. From October 2020 to February 2025 he ran Telekom Deutschland GmbH, the parent's largest operating country. T-Mobile's proxy statement records what he did there: doubled the company's growth rate, scaled fiber to connect millions of homes, achieved record mobile market share.

Before Deutsche Telekom there was Bharti Airtel in India, Capital One in the United Kingdom, Vodafone, and T-Mobile UK, where he worked on the joint venture with Orange. He studied business administration at St. Stephen's College in New Delhi and took his MBA at the Indian Institute of Management in Ahmedabad. He has sat on the boards of Mercedes-Benz Group AG, Henkel and BT Group.

Thirty years inside the same industry, on the far side of an ocean - and for four of them, on the far side of T-Mobile's own boardroom table.

The First Year Paid Out

The 2025 books closed well. Net cash provided by operating activities of $28.0 billion. Adjusted Free Cash Flow of $18.0 billion. Fourteen billion dollars returned to stockholders. J.D. Power rated T-Mobile highest for network quality in five of six U.S. regions, against a previous best of two, ending a run of 35 consecutive reports in which a competitor had led the category. "In 2025, more new postpaid customers chose the Un-carrier than ever before," Gopalan said on February 11.

He used the same day to raise the target rather than bank it. At a Capital Markets Day Update, T-Mobile lifted the multi-year plan it had set in September 2024: service revenues of roughly $77.0 billion in 2026 and $80.5 to $81.5 billion in 2027, Core Adjusted EBITDA of $40.0 to $41.0 billion by 2027, 18 to 19 million total broadband customers by 2030, and nearly $3 billion of incremental Core Adjusted EBITDA from digitalisation and AI by the end of 2027. As he put it that day: "T-Mobile is raising the bar on what customers, stockholders, and the industry can expect from the Un-carrier."

Two quarters later the raising ran into the counting.

The Accounts Slowed Down

The first quarter of 2026 grew accounts and shrank earnings. Postpaid net account additions of 217 thousand were up 6 percent; net income of $2.5 billion was down 15 percent and diluted earnings per share of $2.27 down 12 percent, carrying $476 million of UScellular merger-related costs net of tax.

The second quarter reversed the pattern. Service revenues of $19.0 billion grew 9 percent. Core Adjusted EBITDA of $9.5 billion grew 12 percent. Adjusted Free Cash Flow reached $4.8 billion. And postpaid net account additions came in at 277 thousand - down 41 thousand, or 13 percent, from a year earlier - while postpaid account churn rose to 0.99 percent from 0.92 percent.

Gopalan led with the number that had gone his way - "including achieving our highest-ever wireless NPS score of 46" - and restated the proposition underneath it: "Our strategy is simple: give customers the best network, the best value, and the best experience, all in one place."

The accounts he is defending still total 34.7 million, against 31.5 million a year before. The rate of addition is what slowed.

Then He Rebuilt The Room

The response was not to the numbers but to the org chart. On July 7, 2026, T-Mobile announced that Chris Sambar, chief operating officer of Public Storage and formerly president of AT&T's network organisation, would join as Chief Enterprise Officer no later than October 14. Gopalan's assessment of him was brief: "Chris is a seasoned wireless industry leader with proven experience". The same release moved Andre Almeida to Chief Marketing, Brand and Broadband Officer, consolidated network, technology, product engineering and cyber under chief technology officer John Saw, and recorded that Chief Business and Product Officer Mike Katz was stepping away, staying as an adviser through December 2026.

Eight weeks after that, on September 3, he replaced his chief financial officer. Jessica Uhl, formerly CFO of Shell and most recently president of GE Vernova, joins as CFO designate in mid-September and succeeds Peter Osvaldik in February 2027; Osvaldik, CFO since 2020, becomes a strategic adviser until his retirement on July 1, 2027. "After a thorough search process, I am confident Jessica is the right leader to help shape our growth agenda as CFO," Gopalan said, adding that "We have a long growth runway to continue our leadership in consumer wireless".

Ten months into the job, the man who arrived from the board has changed the enterprise chief, the marketing chief, the technology reporting lines and the finance chief.

The Count Is Due

The same September 3 release reaffirmed the 2026 guidance: between 900 thousand and 1.0 million postpaid net account additions for the year. Through six months, T-Mobile has 494 thousand - behind the 523 thousand booked over the same stretch of 2025.

That leaves between roughly 406 and 506 thousand accounts to find in two quarters, with a new enterprise chief who does not start until October and a finance chief who does not take the seat until February.

The third quarter closed on September 30. The first number of Gopalan's second year is the one that will be counted.
