Deutsche Telekom shelves T-Mobile US merger offer as board opposition bites

Deutsche Telekom has decided against making a formal offer to merge with its US subsidiary T-Mobile US for now, after the plan ran into resistance inside its own governance structure, Bloomberg reported. The German operator, which holds close to a 53% stake in T-Mobile US, has not abandoned the idea of a full combination, according to the report, and could still bring an offer later.

The obstacle is internal. Deutsche Telekom's works council and trade unions, which together account for 50% of the company's supervisory board seats, opposed the proposed transaction, Bloomberg stated. Under Germany's codetermination regime, employee representatives hold half the seats on the supervisory board of large companies, a structure that gives labour a direct veto position over strategic decisions of this scale. Any full-combination offer would have needed to clear that board before it could reach shareholders.

The plan is recent but not new. Bloomberg first reported in April that Deutsche Telekom was interested in a merger with T-Mobile US. The company became the majority stakeholder in the US operator in 2024 and now controls close to 53% of the shares.

What changed between April and now?

Two forces converged. First, the works council and union opposition. Second, an activist shareholder. Last month, Bloomberg reported that Elliott Investment Management had built a sizeable stake in Deutsche Telekom and was pressing the operator to drop the merger plan entirely.

Elliott's involvement adds a market-side counterweight to the boardroom resistance. An activist investor pressing against a transaction typically argues the deal would destroy value or divert capital from other uses, although Bloomberg's reporting did not detail the fund's specific objections. What is clear is that Deutsche Telekom now faces pressure from two directions at once: labour representatives inside the supervisory board and a hedge fund outside it.

The word from Bloomberg on timing matters. The outlet reported Deutsche Telekom could still bring an offer later. That framing suggests a delay rather than a termination. No formal offer was ever tabled, so nothing was formally withdrawn. The company has simply decided, for now, not to move.

What does this change for T-Mobile US?

In operational terms, very little. T-Mobile US continues to operate under its own leadership, and that leadership already has direct Deutsche Telekom pedigree. Srini Gopalan, formerly the head of Deutsche Telekom's German unit, is now chief executive of T-Mobile US. The US operator has been run for years with the German parent as its dominant shareholder, and Deutsche Telekom has steadily accumulated T-Mobile US shares in recent years, moving from a minority position to majority control in 2024 and on to close to 53% today.

What the stalled merger leaves open is the structural question of ownership. A full combination would have collapsed the remaining gap between parent and subsidiary, folding T-Mobile US entirely into Deutsche Telekom. That question remains unanswered, only postponed.

The timeline from here is undefined. Bloomberg's reporting points to three moving parts to watch: whether Deutsche Telekom can win over its supervisory board's employee representatives, whether Elliott escalates or settles, and whether the operator decides the economics still justify a renewed offer. None of these carries a date. The only firm marker in the record is April, when the merger interest first surfaced, and the gap since then has been filled with opposition rather than progress.

For now, Deutsche Telekom stays where it has been: a majority owner with a controlling near-53% stake, a former unit chief running the US business, and a merger plan parked rather than killed.
