Deutsche Telekom's US Engine Powers the Group, but Shareholders Capture Less of It Than They Think

Two-thirds of Deutsche Telekom's revenue now flows through T-Mobile US, yet a fresh Warren-Wise analysis published by CPT GmbH argues that operating momentum at the American subsidiary is not the same thing as value delivered to shareholders of the parent. Currency effects and the minority holders in the US business sit between the two — a distinction that matters more than usual as a new competitive threat takes shape.

The scale of the US operation is hard to overstate. T-Mobile US counts nearly twice as many mobile customers as Telekom Deutschland, and Deutsche Telekom holds roughly 54% of the subsidiary. That stake, rather than the German home market, is the single biggest swing factor in how the group is valued.

Growth and shareholder return are not the same ledger

For 2025, the analysis puts revenue growth at a little over 4%, adjusted for currency movements and acquisitions. Free cash flow after leases came in at around EUR 19.5 billion. Guidance was raised several times over the course of the year — evidence of genuine operating dynamism.

The picture inside the group is uneven, though. Germany is described as the more profitable but slower-growing part of the business, while the US supplies the expansion. Investors are left weighing two different sets of strengths against each other rather than reading a single growth number.

The Warren-Wise work is model-driven and does not constitute an independent analyst rating. Its contribution is the separation it draws between operational growth and what actually reaches Telekom shareholders — a gap that exchange rates and the structure of the US shareholding both widen or narrow.

A spectrum deal, not yet a rival network

Competition has entered the calculation alongside currency. SpaceX agreed in early October to buy a nationwide low-band spectrum portfolio from Grain Management, a move first reported by Reuters on 9 October. The FCC has not yet approved use of those frequencies.

Markets read the announcement as a signal of a stronger mobile challenger, and Telekom shares felt the weight of it. The reaction is understandable given the size of the US exposure, but an announced spectrum purchase is not the same as an established competitive position, and it does not by itself show how forcefully Starlink will compete once — and if — it launches.

ODDO-BHF analyst Stéphane Beyazian expects that a competitive SpaceX mobile offering without a roaming partner could take years to build. That view tempers fears of a rapid market entry without disposing of the longer-term question.

AI: two levers, one long horizon

Back in Germany, management's own case rests on confirmed targets. At its AI investor day on 5 October, Deutsche Telekom reaffirmed both its outlook and its medium-term goals. The company expects roughly EUR 800 million in AI-related revenue from its enterprise business outside the US by 2030, and around EUR 2.5 billion in indirect cost savings from AI and automation by 2030 compared with 2023.

The two figures do different jobs. New revenue demonstrates demand; lower indirect costs feed earnings from a different direction. Neither is a fully realised contribution today, and the announced relief should not be assumed to be immediately available — nor to offset any US headwind automatically.

A product launch in the mix

On Tuesday the group began German sales of the Meta Ray-Ban Display, priced at EUR 899 without a plan and also available bundled with a mobile contract. It is a useful addition to the product range and can support trading, but it is not the reason to own the stock. Confirmed targets and the prospect of efficiency gains carry more weight.

November 5 is the next real test

Third-quarter results, scheduled for 5 November, will give investors the first hard data point since the guidance was reaffirmed. What matters then is the link between reported performance and the confirmed outlook — a more informative signal than a single device launch or the mere announcement of a possible new competitor.

If operations hold up the targets while AI initiatives begin to show through, the investment case rests on more than incremental sales. If confidence in target delivery slips at the same time as US competitive risks become concrete, the balance should tilt more cautiously. Long-run AI expectations on their own would not be enough to answer near-term operating strain.
