Deutsche Telekom: Buyback Support and Fiber Momentum Face a T-Mobile Litmus Test

DT shares climb above 50-day moving average ahead of August 6 half-year results, but T-Mobile US weakness and 12% YTD decline temper optimism.

The Deutsche Telekom share has clawed its way back above a key technical threshold, but the real test arrives on August 6 when the group's half-year numbers will reveal whether the recovery has genuine legs or is merely a temporary reprieve.

Shares climbed 2.19 percent to €27.51 on Tuesday, pushing through the 50-day moving average of €27.12 — a level that had trapped the stock for weeks. The move extends a monthly gain of roughly 10.5 percent, though the year-to-date picture remains bleak with a decline of nearly 12 percent. At €27.51, the stock still sits almost 20 percent below its 52-week high of €34.35, a reminder of how much ground remains to be recovered after a three-month slide that wiped out roughly a third of the share price and drove it as low as €24.

The Buyback Cushion

Management has been quietly shoring up the stock from the sidelines. Between July 20 and 24 alone, the company repurchased roughly 1.35 million of its own shares, bringing the July total to around five million. These buybacks act as a demand buffer, absorbing excess supply and providing a floor beneath the recovery.

On the operational front, the domestic business is delivering. Deutsche Telekom added 240,000 new fiber connections in June, widening its lead in the German broadband market. By contrast, rival Vodafone shed 85,000 mobile and 98,000 broadband customers over the same period. The home market is strengthening even as competitors retreat.

The T-Mobile Overhang

Yet the real weight on the stock comes from across the Atlantic. T-Mobile US delivered a strong second quarter — earnings per share of $2.99 comfortably beat expectations — but the market focused on what was missing. Revenue fell short of forecasts, and customer additions disappointed. The stock dropped roughly 4 percent in pre-market trading, dragging its German parent lower in sympathy.

That reaction exposed a structural vulnerability. T-Mobile US accounts for a dominant share of the group's growth story, and any wobble in the subsidiary's market reception reverberates directly through the parent's share price. JPMorgan recently trimmed its price target for Deutsche Telekom from €40 to €38, citing more cautious estimates for the US unit.

Adding to the uncertainty, reports emerged on July 27 of network outages at T-Mobile US. Whether those disruptions translate into meaningful customer churn remains unclear, but they add another layer of risk ahead of the earnings release.

There is also a near-term headwind baked into the US outlook. T-Mobile US has warned that the third quarter will see temporarily weaker subscriber growth as customers transition to new, more expensive tariff plans — a shift that historically triggers some cancellations before stabilizing.

The Chart Battle

The technical picture is cautiously constructive but far from resolved. The 50-day moving average has been recaptured, and the relative strength index at 57.7 leaves room for further upside before overbought territory is reached. But the next hurdles are steep: the 100-day average sits at €28.56, and the 200-day average at €28.64. A sustained break above both would signal that the multi-month downtrend is genuinely reversing.

The downside risks are equally concrete. The 30-day annualized volatility stands at 33.7 percent, underscoring how quickly sentiment can shift. Should the stock lose the €27.12 level again, the €26 mark would likely be tested as support. A disappointing earnings report could accelerate a slide toward the 52-week low of €23.54, a level touched as recently as late June and currently only about 16 percent below the current price.

What August 6 Will Decide

The half-year report on August 6 will be the decisive catalyst. Investors will scrutinize two metrics in particular: the operating margin in the German fiber business and the adjusted EBITDA guidance for the US operations. The group has already laid out ambitious targets — adjusted EBITDA after leasing costs of roughly €47.5 billion for 2026, up from €44.7 billion on a pro-forma basis, with free cash flow after leasing seen at €19.8 billion versus €19.3 billion in 2025. T-Mobile US has also raised its adjusted free cash flow guidance for 2026 to a range of $18.4 billion to $18.8 billion, up from $18.1 billion to $18.7 billion.

The question is whether the operational strength in Germany and the buyback support can offset the headwinds from the US. If the August 6 numbers confirm that the domestic business is compensating for any softness at T-Mobile, the stock has a credible path toward testing the €28.60 resistance zone. If the US outlook disappoints, the fragile recovery could unravel quickly, with the 52-week low looming as the next reference point.
