Deutsche Telekom Secures Landmark A- Rating and Lifts Guidance, Yet Labour Dispute and Domestic Pricing Woes Weigh on Stock

Despite first-ever A- credit rating and T-Mobile US driving higher guidance, Deutsche Telekom's share price stays flat due to domestic tariff competition, labor strikes, and costly fiber rollout.

The German telecoms giant finds itself caught between a string of positive corporate developments and stubborn headwinds that continue to pin down its share price. On Thursday, the stock changed hands at €27.79, a decline of 1.59% on the day, extending its year-to-date retreat to just above flat. The muted performance comes despite a credit-rating upgrade that pushes the company into an elite category for the first time and a guidance lift driven by its high-flying US subsidiary.

S&P Global Ratings raised Deutsche Telekom’s long-term credit rating to A- on 12 May 2026, marking the first time the group has entered the A band. For a capital-intensive telecom operator constantly ploughing money into networks and spectrum, the move signals a materially stronger balance sheet and could lower refinancing costs. Yet the timing is awkward: the domestic market is under pressure from tariff competition, and the same week the upgrade was announced, quarterly earnings painted a mixed picture of modest revenue growth and a profit dip, though management did tweak the full-year forecast modestly higher.

A key driver of that improved outlook is T-Mobile US. The American arm, in which Deutsche Telekom now holds nearly 54%, is expected to lift adjusted group EBITDA to around €47.5 billion in 2026, with free cash flow rising above €19.8 billion. In the first quarter, the entire group generated an operating result of €11.5 billion – a figure that would have shown stronger growth without the headwind from a weaker US dollar. Management is betting on artificial intelligence to sustain momentum: a new chatbot already routed one million calls in Q1, a volume set to double over the year, and Nvidia chip capacity in Munich is fully booked.

The fibre rollout remains a costly but essential pillar of the strategy. Last year Deutsche Telekom connected 3.6 million European households to its fibre network, and around 2.2 million German customers are now active fibre users. To maintain the expansion pace, the company is adding €800 million to its investment budget. That spending commitment, however, comes at a time when the home market is grappling with an escalating labour dispute. The Ver.di union is demanding a 6.6% wage increase for tariff employees, and 9,000 workers recently downed tools in warning strikes that, for the first time, included staff at sales and IT subsidiaries.

Analysts on the sell side remain broadly constructive despite the share price weakness. UBS reaffirmed a Buy rating on 14 May with a €36.20 target, while JPMorgan stuck with Overweight and a €40 target the day before, calling the quarterly trends “in line”. Goldman Sachs and Deutsche Bank also issued positive notes on Thursday, highlighting the underlying operational strength and the improved credit profile. Still, the stock sits below its 50-day moving average, and technical indicators suggest caution rather than euphoria.

The next catalyst will come when the fourth round of wage negotiations begins in a few weeks. Until then, investors are weighing the tailwinds from a stronger balance sheet and a US-driven earnings upgrade against the drag from domestic cost inflation and pricing pressure. For the share price to finally catch up with the fundamentals, the company will need to deliver on its slightly raised guidance and find a resolution to the labour standoff – neither of which is a given in the current environment.
