Merger Speculation, Lapsed Buyback, and a Regulatory Storm Pile Pressure on Deutsche Telekom

Deutsche Telekom stock plunges 7% to year low on unconfirmed T-Mobile merger reports, buyback expiration, and regulatory risks, overshadowing strong Q1 earnings.

Strong operating momentum and a freshly upgraded credit rating have done little to protect Deutsche Telekom from a vicious market rout. The stock plunged more than 7% on Monday to €24.37, hitting a new year low of €24.20 intraday. That extends its year-to-date decline to nearly 13%, turning the Bonn-based telecoms group into one of the worst performers in the Dax.

The sell-off was triggered by unconfirmed media reports that the company is considering a full merger with its U.S. subsidiary, T?Mobile US. Deutsche Telekom currently owns just over half of the American mobile operator, which already dominates the group’s earnings. Investors fear that a full integration could result in unfavorable exchange ratios for existing Telekom shares. Management has officially denied any sale plans for 2026, but has signaled it is exploring ways to further expand the lucrative U.S. stake. Bloomberg has described any such deal as potentially one of the largest acquisition in corporate history.

Adding to the pressure, a key buyer is stepping away from the market. A tranche of the ongoing share?buyback program, which has seen the company repurchase roughly 17 million of its own shares since April, expires on Tuesday. That dependable source of demand will now vanish, at least temporarily, leaving the stock without a crucial support cushion.

Meanwhile, the Federal Network Agency (Bundesnetzagentur) is testing actual network quality across Germany. The results, due in the autumn, could impose costly new requirements on infrastructure spending. These regulatory risks are overshadowing an otherwise robust operational picture. The rating agency Fitch recently upgraded Deutsche Telekom’s credit rating to A-, citing strong cash?flow generation.

Technical indicators reflect the severity of the sell?off. The relative strength index (RSI) has plunged to 22.8, deeply into oversold territory. The stock is now trading well below the previous year?to?date low of €25.71 that some analysts had flagged as a potential floor.

On the fundamental side, the group delivered a solid first?quarter performance: revenue rose to just under €29.9 billion, while adjusted EBITDA climbed 7.5% to €11.5 billion. Management has reaffirmed its full?year targets, including EBITDA of around €47.5 billion and free cash flow exceeding €19 billion. But these strong numbers have been largely ignored by a market fixated on corporate structure and regulatory risk.

The immediate catalyst for a potential turnaround is the second?quarter results, due on August 6. By then, the board will need to provide clear answers on the M&A rumors to arrest the current downtrend. Until that clarity arrives, the stock remains exposed to further weakness, especially without the buyback as a backstop.
