Deutsche Telekom Waits on T-Mobile US Earnings After Historic 8-Million-Customer Tariff Overhaul

Deutsche Telekom shares edge lower as T-Mobile migrates 8M legacy users to higher-priced tiers. Analysts bullish, but stock down 13% over 12 months.

T-Mobile US, the American cash cow that powers the bulk of Deutsche Telekom's profits, has kicked off the largest forced tariff migration in its corporate history. Beginning this week, more than 8 million customers on legacy Magenta, ONE and Simple Choice plans are being shifted into new, pricier "Experience" tiers, with monthly bills rising by as much as $6 per line. The move marks a clean break from the Un-Carrier brand that fueled the company's growth under former CEO John Legere, and puts Deutsche Telekom's stock under a fresh spotlight as investors weigh the revenue uplift against the risk of customer churn.

The Bonn-based parent saw its shares edge lower on Tuesday, trading at €26.57, a 0.6% decline from Monday's close of €26.73. The dip comes despite two major sell-side endorsements. JPMorgan reaffirmed its Overweight rating with a €40 price target, implying upside of more than 50%, while UBS analyst Polo Tang stuck to his Buy rating and €36.20 target, citing expectations for solid second-quarter results. Deutsche Telekom itself is due to report on August 6, while T-Mobile US will unveil its numbers on July 23 — the first hard look at the financial fallout from the tariff revamp.

Short-term performance tells a mixed story. On a seven-day basis, the stock has gained 2.98%, bouncing from last week's low. But the downtrend over longer horizons remains intact: the shares have lost 4.70% in the past month, 4.66% year-to-date, and 13.23% over the past twelve months. From the 52-week high of €34.35 touched in late February 2026, the stock has fallen 22.65%; from the June low of €23.54, it sits 12.87% higher. Technical indicators show a neutral posture — the relative strength index stands at 51.7, while the annualised 30-day volatility of 31.30% reflects persistent jitters. The stock currently trades just below its 50-day moving average of €27.35 and well beneath the 200-day average of €28.74.

Chart-watchers see the recent retreat as overdone, noting that resistance in the €26.00 to €26.50 zone has been cleared. Next upside targets are pegged at €28.81 and €28.83. Analysts also expect double-digit earnings-per-share growth as the tariff migration starts to feed through — the first higher bills will land in August, just as the autumn smartphone cycle begins.

At the corporate level, Deutsche Telekom continues to execute a €2 billion share buyback programme for the current year. In the first week of July alone, the company repurchased 909,000 of its own shares. The programme, alongside analyst confidence, offers a floor for the equity even as strategic uncertainty lingers. Plans to create a holding structure around T-Mobile US have drawn criticism from major shareholders, including the German government, which owns 28% of Deutsche Telekom. The outcome of that debate remains open.

For the US subsidiary, the tariff overhaul is the third tightening measure in 2026. It follows cuts to device-subsidy limits in April and the forced migration of Magenta Plus and MAX subscribers to the Go5G Plus plan earlier this year. To ease the transition, T-Mobile is offering a five-year price guarantee, free streaming add-ons, and the preservation of existing free lines and tax structures. The company has introduced 62 new tariff codes to replace 1,100 old ones. Competitors AT&T and Verizon have already launched targeted campaigns to lure disaffected T-Mobile customers.

Despite the near-term pressures, Wall Street sees significant value in T-Mobile US. The consensus of 28 analysts points to a median price target of $257.35, implying a 39.31% upside from the last closing price of $184.73. For Deutsche Telekom, which commands a market capitalisation of €122.6 billion, the performance of its US jewel remains the single most important variable — and Thursday’s earnings will provide the clearest gauge yet of whether the price hike gamble is paying off.
