Telekom's Success Paradox: When Outperformance Becomes the Bear Case
Published on 09/02/2026 at 12:31 | Editorial boerse-global.de
There is an uncomfortable irony hanging over Deutsche Telekom's stock right now. The very engine of its recent success — the relentless growth of T-Mobile US — has become the reason analysts are telling investors to temper their enthusiasm.
Kepler Cheuvreux cut its rating on the German telecom giant from "Buy" to "Hold" on August 27, trimming the price target from €35 to €32. Analyst Florian Treisch framed the downgrade in strikingly counterintuitive terms: the company has become a victim of its own achievements. The problem isn't operational weakness — it's that expectations have simply run ahead of what the market can reasonably price in.
A Stock Drifting From Its Peak
The shares, currently trading at €28.33, sit roughly 18 percent below their 52-week high of €34.35 reached in February. Over the past seven trading sessions alone, they have shed 2.3 percent. The stock now hovers barely one percent above its 200-day moving average of €28.61 — a technical signal that suggests a relatively stable, if uninspired, medium-term trajectory.
Treisch's caution centers on two fronts: intensifying competitive pressure at T-Mobile US and questions over margin stability across the broader group as the second half of 2026 approaches.
The $300 Billion Deal That Wasn't
Far more consequential than the downgrade, however, is the quiet collapse of a transatlantic mega-merger. Late in July, T-Mobile US leadership informed its German parent that they could no longer support a planned $300 billion combination. The reasoning was pragmatic: management concluded that non-controlling shareholders of T-Mobile US would reject the transaction, making minority approval an unrealistic prospect. By early August, media reports confirmed the deal was officially dead.
Should investors sell immediately? Or is it worth buying Deutsche Telekom?
The failure deals a blow to Deutsche Telekom's ambitions to restructure its American operations — even if the underlying business there continues to hum along. T-Mobile US posted 9.6 percent organic EBITDA growth in the first half and added 0.5 million customer accounts. Operationally, nothing has changed; strategically, the questions about long-term group structure are now harder to ignore.
Solid Numbers, Rising Ambitions
The contrast between these headwinds and the group's actual financial performance is stark. In the second quarter, revenue grew organically by 3.3 percent to €29.9 billion, while adjusted EBITDA advanced 7.3 percent to €11.8 billion. Free cash flow climbed 3.1 percent to €5.0 billion, prompting management to lift its full-year guidance to approximately €20.0 billion — up from the previous forecast of over €19.8 billion.
That cash flow figure is the metric that matters most. It underpins both the dividend and an expanding share buyback programme that the board enlarged in August by up to €3 billion, bringing the total for the year to as much as €5 billion. Roughly €1.2 billion of repurchases are already underway, signalling that management sees ample financial headroom to return capital without straining the balance sheet.
The guidance upgrades have followed a consistent pattern: revenue and EBITDA forecasts were raised in May, followed by the cash flow increase in August. This is a company that keeps beating its own targets — a habit that bolsters the bull case that Kepler's downgrade may prove a snapshot rather than a turning point.
A Security Flaw Adds to the Noise
Beyond the strategic and valuation concerns, a separate issue has put the company on the defensive. Investigations by Bavarian public broadcaster BR, involving more than 70 test calls conducted in August, revealed that IMEI numbers were leaking to callers across networks operated by Deutsche Telekom and Telefónica. In isolated cases involving Telekom and Vodafone, callers could even discern smartphone models and operating system versions — a vulnerability traced to VoLTE connections.
The GSMA industry association stressed that user identities were not exposed, but the reputational risk is real. Deutsche Telekom says it has implemented network changes to strip affected metadata at the network boundary and is in discussions with industry bodies and the Federal Network Agency. Regulatory consequences remain unclear, yet the episode adds another layer of uncertainty to a stock already wrestling with multiple narratives.

The political backdrop doesn't help: the ongoing debate over Huawei technology in German mobile networks keeps cybersecurity firmly in the public eye, meaning any technical lapse carries outsized reputational weight.
What Comes Next
The bull case rests on momentum. If T-Mobile US continues to perform and the cash flow guidance holds, the current €32 price target could soon look conservative. The recently agreed acquisition of Polish fibre operators Fiberhost and Inea for around €1 billion — still pending regulatory approval — suggests management is willing to buy growth as well as generate it organically.
The bear case is equally coherent. When an analyst downgrades a stock precisely because its strongest division is doing too well, it reveals fragile expectations: any slowdown at T-Mobile US could hit the parent's share price disproportionately. Add the security questions and the regulatory scrutiny around network infrastructure, and there is no shortage of potential catalysts for further caution.
Investors will get their next clues on October 5, when the company hosts its AI Investor Day, followed by third-quarter results on November 5. Until then, the central question remains whether Telekom's success story continues to drive the share price — or becomes the very weight that holds it down.
