Telekom's €3bn Buyback and Polish Fibre Deal Collide With a Fresh Security Scare

Deutsche Telekom expands buybacks and buys Polish fiber assets, but a data security issue pressures shares below key technical level.

The arithmetic of Deutsche Telekom's capital-return story is straightforward enough: buy back more than 1.6 million shares in a single week, expand the repurchase programme by €3bn, and add a €1bn fibre acquisition in Poland. The market's reaction, however, tells a more complicated tale.

On Wednesday, the stock closed at €28.97, having gained 5.2% over the prior 30 days and 4.2% since the start of the year. The following session, those gains came under immediate pressure as the shares slipped 3.3% to €28.02, dragging the price back below its 200-day moving average of €28.58 — a gap of roughly 2.0%.

The trigger was not a deterioration in the underlying business. Rather, it emerged that German mobile networks, including Telekom's, had transmitted sensitive device data — IMEI numbers, handset model and operating system versions — to callers during voice calls. Germany's Federal Office for the Protection of the Constitution classified the issue as security-relevant, and the GSMA alerted more than 1,000 companies. The network operators said they had already implemented countermeasures.

A Two-Track Strategy in Motion

The security disclosure lands at a moment when the company is executing on both sides of its capital-allocation playbook. Between 10 and 14 August, Telekom repurchased 1,601,600 of its own shares, the first interim update on a programme that was expanded in early August by up to €3bn — an increase announced alongside the second-quarter financial report.

That report showed earnings per share of €0.58 on revenue of just under €29.9bn. Management also raised the full-year free cash flow guidance, signalling that heavy investment in the fibre network would not come at the expense of shareholder distributions.

In parallel, the company has moved to expand its fixed-line footprint beyond Germany. Reuters reported that Telekom agreed to acquire Polish network operator Fiberhost and broadband and TV provider Inea from Macquarie Asset Management for around €1bn, with completion expected by the end of 2026.

The two initiatives — repurchases and the Polish acquisition — are independent of one another, yet they reinforce the same message: the company is generating enough cash to fund external growth while simultaneously reducing its share count.

Technical Levels in Focus

For chart-watchers, the immediate question is whether the stock can reclaim the 200-day average. A sustained failure to hold that level would undermine the case that the shares have broken out of their longer downtrend. The 50-day average at €27.11 could offer support if the pullback extends, though the current 30-day volatility reading of 34% suggests swings in either direction remain likely.

The RSI at 48.5 points to a market that is neither overbought nor oversold — an indication that investors are treating the security issue as an open question rather than a decisive negative.

Still, the stock sits 16% below its 52-week high of €34.35, reached in late February. The distance to that peak puts the recent recovery in perspective, even as the buyback programme provides a structural bid for the shares.

What Could Shift the Narrative

The security vulnerability carries a different risk profile than an operational miss. Because the Federal Office for the Protection of the Constitution has explicitly flagged the issue as security-relevant, the potential for regulatory follow-up cannot be dismissed. Should further details emerge about the scope of the data transmission, or should supervisory authorities pursue consequences, investor attention could shift from the growth story to reputational exposure.

The near-term signal to watch is the response of the authorities. If the technical measures already taken by the network operators prove sufficient, the episode may fade quickly from the market's radar. If it escalates — through additional regulatory steps or litigation — the buyback programme and the Polish deal could find themselves competing for attention with a more defensive narrative.

For now, the operational momentum from the quarterly results and the pace of the repurchase programme — more than 1.6 million shares absorbed within a handful of trading sessions — give the bulls a credible case. The question is whether that case can withstand the noise from Berlin.
