Deutsche Telekom: Union Ballot and T-Mobile Merger Speculation Weigh on Stalling Shares

Shares drop 5% as Friday's union vote may secure labor peace, but full integration of T-Mobile US risks political backlash over German state stake dilution.

Deutsche Telekom finds itself caught between two powerful but opposing currents this week. A make-or-break union vote on Friday promises to remove a cloud of labour uncertainty, while escalating chatter about a full integration of T-Mobile US threatens to unleash a political firestorm that could depress the stock further. At €26.95, the shares have shed nearly 5% in the past week and sit more than 21% below the February peak – a stark contrast to the solid operational momentum the Bonn-based group is reporting.

The immediate catalyst for investors is tomorrow’s ballot by the ver.di trade union commission on the new pay package covering roughly 60,000 employees. If approved, the 33-month agreement will rule out compulsory redundancies until the end of 2028 and deliver a monthly pay supplement rising in two steps to a total of €290. From June 2028, base salary tables will be lifted by an additional 2.4%. Analysts peg the overall cost of the deal at about 8.5%. A “yes” vote would lock in labour peace and predictable personnel expenses for the next two and a half years, shielding the company from surprise strike costs and allowing management to refocus on the fibre roll-out.

Operationally, the first quarter was strong. Organic revenue climbed 4.7% and adjusted EBIT jumped 7.5%, prompting the board to raise its full-year guidance. For 2026, the group now targets an adjusted operating profit of roughly €47.5bn. The dividend for last year has been lifted to €1.00 per share, and an ongoing share buyback programme – whose latest tranche of up to €550m ends this month – is steadily supporting the equity. Last week alone, Telekom repurchased 1.6m of its own shares. Technical signals hint at a possible floor: the relative strength index has fallen to 34.6, close to oversold territory.

Yet the market’s gaze is fixed on a much larger structural question: the potential full integration of T-Mobile US. A Wall Street Journal report has revived speculation that the parent intends to create a new holding company that would issue an all-stock offer for both entities. Berlin, however, stands squarely in the way. The German federal government and state-owned KfW together hold approximately 28% of Deutsche Telekom. A full merger would dilute their combined stake to an estimated 17-18%, pushing the state below the politically sacrosanct 25% blocking minority threshold. Whether the coalition in Berlin would ever consent is unclear; US regulators and minority shareholders would also need to sign off.

Until a formal proposal emerges, the stock remains hostage to these twin unknowns. The positive Q2 figures, due on 6 August, could provide a fresh catalyst, but the most immediate event is Friday’s union verdict. A positive outcome would remove one layer of risk and give investors a fixed cost base through mid-2028. The merger speculation, however, seems unlikely to fade quickly – and the political dimensions mean it will remain a drag until Berlin’s position becomes clearer.
