Deutsche Telekom's Transatlantic Puzzle: Buybacks, Merger Talk, and a Share Price Under Pressure

Deutsche Telekom's €36M buyback fails to lift stock as T-Mobile merger talks, political hurdles, and overbought signals pressure shares to €27.70.

The German telecoms giant is fighting on multiple fronts. While management deploys a €36 million share buyback to shore up confidence, the spectre of a transatlantic restructuring is weighing heavily on the stock. The result? A share price that has shed roughly ten percent over the past month, landing at €27.70 — well below its 50-day moving average of around €31.

A Buyback Blitz Meets Structural Headwinds

In the final week of April alone, the Bonn-based group repurchased approximately 1.3 million of its own shares, channelling more than €36 million into the market. Since the programme kicked off at the start of April, Deutsche Telekom has retired nearly 5.8 million shares, a move designed to shrink the capital base and boost earnings per share for remaining holders.

Yet the market has barely blinked. The stock now sits roughly 19 percent below its 52-week high, and technical indicators flash warning signals: the relative strength index hovers near 72, a level that historically suggests an overbought condition and creates downward pressure.

The Elephant in the Room: A US-German Holding Structure

The real drag on sentiment stems from speculation about a potential merger of Deutsche Telekom and its US subsidiary T-Mobile under a single holding company. The proposal, still in its early stages according to reports, would see the new entity listed on both American and European exchanges, modelled on the Praxair-Linde tie-up of 2018 that used an Irish holding company as a neutral wrapper.

The logic is compelling. More than 70 percent of Deutsche Telekom's enterprise value — roughly €135 billion — is already tied to its T-Mobile stake. Frankfurt has become little more than a shell around a US wireless powerhouse. Currently, the parent consolidates 100 percent of T-Mobile's operating results but receives only 54 percent of its cash flow. A holding structure would eliminate that inefficiency.

Berlin's Red Line and Washington's Scrutiny

Political obstacles loom large. The German government and state-owned KfW together hold around 28 percent of Deutsche Telekom. A merger would dilute that stake to an estimated 17-18 percent, slipping below the informal 25 percent threshold that Berlin has historically viewed as a floor for strategically important companies.

Across the Atlantic, US Congressman Jim Jordan has already signalled that any deal will face close examination. On the corporate side, any capital measure would require 75 percent approval from Telekom shareholders. T-Mobile has dismissed the reports as "speculation" and declined to comment further, while Deutsche Telekom has refused all statements. Management could still decide to walk away from the project entirely.

T-Mobile's Operational Strength vs. Rising Churn

The US arm continues to deliver. T-Mobile US reported first-quarter 2026 revenue of $23.1 billion, a gain of more than ten percent. The operator added 217,000 new postpaid customers — ahead of expectations — and raised its full-year net customer addition forecast. Core EBITDA climbed twelve percent.

But the competitive landscape is tightening. DZ Bank recently trimmed its fair value estimate for T-Mobile US to $250, with analyst Matthias Volkert pointing to a slight uptick in customer churn in North America. Still, the bank maintains a buy rating, noting that the strong overseas earnings continue to fund the parent's hefty European infrastructure investments.

Fibre in the Fields, Eyes on the Balance Sheet

While the transatlantic drama plays out, the domestic network build-out presses ahead. This week, the group launched a new regional fibre project in Edling, Upper Bavaria, targeting hundreds of households for high-speed connections by 2028. The expansion is part of a broader push that sees the telecoms giant laying thousands of kilometres of glass fibre across Germany.

All eyes now turn to May 13, when Deutsche Telekom publishes its first-quarter results. The group has guided for full-year adjusted EBITDA of roughly €47.4 billion and free cash flow of about €19.8 billion. Strong numbers would lend concrete fundamental support to the merger narrative — and test whether T-Mobile's operational firepower is truly translating into group-level returns.
