Deutsche Telekom: Spectrum Swap Clears US Hurdle, Yet Merger Jitters Keep Stock in Check

US regulator approves T-Mobile's $2.9B spectrum exchange with Grain Management, but Deutsche Telekom shares remain weighed by takeover speculation and Musk rumors.

The US regulator has given the green light to a $2.9 billion spectrum swap between T-Mobile US and investor Grain Management, a deal that strengthens the mobile carrier’s network assets at a time when its parent company’s stock is wrestling with takeover uncertainty. The Federal Communications Commission approved the transaction on July 1 and 2, imposing shorter buildout deadlines than originally proposed — three and eight years instead of six and twelve — to prevent the frequencies from sitting idle.

T-Mobile US will hand over its 800 MHz licenses to Grain, which are of limited use to the operator, in exchange for Grain’s 600 MHz holdings plus $2.9 billion in cash. Analysts see the move as a clear win for the US subsidiary, since the 600 MHz spectrum can be deployed to improve both capacity and connection speeds for customers. The deal had been announced back in March 2024 but needed regulatory sign-off.

While the FCC’s decision removes one overhang, the parent company’s shares remain under pressure from a different source. Deutsche Telekom stock closed Friday at €25.22, down 0.32%, after hitting a 52-week low of €23.54 in late June. The subsequent bounce has lifted the stock 7.14% above that trough, but it still sits 26.58% below the year’s high of €34.35 reached on February 27. Over the past 30 days the shares have shed 10.09%, and the year-to-date loss stands at 9.51% — or 18.70% on a 12-month view.

The technical picture shows a market that is weak but no longer screaming oversold. The relative strength index reads 37.4, marginally better than the extreme levels seen during the plunge. That improvement partly reflects a rebound in T-Mobile US shares on Wall Street, which climbed 4% this week. Deutsche Telekom holds roughly 53% of the US operator, and that stake accounts for 65.4% of group revenue in the first nine months of 2025, giving the parent stock a direct line to T-Mobile’s fortunes.

But the driver of the original selloff — speculation that CEO Tim Höttges is pushing for a full integration of T-Mobile US — continues to rattle investors. No official statement has been made, and the market remains split on whether a tie-up would create value or pile on complexity. Adding to the noise are unconfirmed reports that Elon Musk is exploring a closer link to the US mobile market, possibly via a partnership with SpaceX or Starlink. Satellite-based telecoms are seen as a long-term threat to traditional carriers, and the prospect of Musk entering the fray has kept the entire sector on edge.

Deutsche Telekom’s €560 million buyback program, in its third tranche running through the end of September, is providing a modest cushion in Frankfurt. The company is using the repurchases to support earnings per share, though the effect has been swamped by the broader uncertainty.

For now, investors are waiting on two catalysts: fresh quarterly figures from T-Mobile US, scheduled for July 23, 2026, and any clarification from Bonn on the merger front. Until then, the stock remains caught between a solid operational story at the US unit — now backed by better spectrum — and a cloud of unanswered questions closer to home.
