Deutsche Telekom Faces a Tale of Two Signals: Analyst Optimism Meets T-Mobile's Risky Tariff Migration

T-Mobile US migrates 8M legacy customers to new plans with up to $6/month increases; JPMorgan sees 53% upside for Deutsche Telekom despite stock trading below key moving averages.

A massive price overhaul at T-Mobile US — affecting eight million legacy customers — is testing the resilience of Deutsche Telekom’s equity story even as JPMorgan insists the stock has more than 50% upside. The US subsidiary, which supplies the lion’s share of group earnings, began migrating subscribers from decades-old plans like Simple Choice, ONE, and Magenta to new "Experience" tiers on July 14. Monthly bills for some customers will rise by as much as $6, though a T-Mobile spokesman said the new rates typically remain below the standard new-customer price. The move, the largest tariff reform in the company’s history, comes with a five-year price guarantee and is aimed at rationalizing a base that still contains contracts from the 3G and 4G era.

JPMorgan analyst Akhil Dattani has kept his Overweight rating and €40 price target on Deutsche Telekom, implying a roughly 53% gain from current levels. In a note published July 10, Dattani pointed to what he calls a historic valuation gap, arguing that double-digit earnings-per-share growth remains sustainable. UBS’s Polo Tang is similarly bullish, reiterating a Buy rating with a €36.20 target and citing optimism for the second-quarter 2026 results from both T-Mobile US and the German home market. The analyst endorsements pushed the stock to the top of the DAX on Monday, when it rose as much as 2.57% to €26.79 via Xetra.

Yet the stock still has a mountain to climb. At Wednesday’s close of €26.49, the shares trade roughly 23% below the 52-week high of €34.35 touched in late February. The recovery from the June 30 low of €23.54 leaves a cushion of about 12%, but the longer-term picture remains weak: the stock is down 4.95% year-to-date, and the 50-day moving average of €27.33 and 200-day moving average of €28.73 both sit above the current price. The relative strength index hovers near 50 — neutral territory — while annualized volatility of 31.24% signals that swings are likely to continue.

Away from the price chart, T-Mobile US is also reshuffling its leadership. Mike Katz stepped down as Chief Business and Product Officer on July 8; Chris Sambar takes over as Chief Enterprise Officer, while André Almeida will now oversee consumer and broadband operations. The management shake-up comes as the carrier finalizes a separate spectrum transaction with investment firm Grain Management, approved by the FCC. T-Mobile is trading its 800 MHz licenses for $2.9 billion in cash plus Grain’s 600 MHz holdings — a deal analysts say cleans up unusable spectrum left over from the Sprint merger and adds valuable capacity.

The tariff migration has inevitably drawn competitive fire. AT&T has already raised prices on its own legacy plans, and Verizon is actively poaching disgruntled T-Mobile customers. Industry margins remain under pressure even as all three carriers push pricing higher. The first higher bills will land in August, coinciding with the autumn smartphone launch window — traditionally a period when churn spikes. T-Mobile’s next quarterly report, due July 23, will offer initial data on how the migration is affecting customer retention, with Deutsche Telekom following on August 6.

Meanwhile, a report in the Neue Zürcher Zeitung has stirred speculation that management is considering folding both Deutsche Telekom and T-Mobile US under a single holding structure to close the valuation gap with the higher-priced American shares. The company has not officially confirmed the plan, but the debate adds another layer of uncertainty to an already complex story. For now, investors are left weighing a torrent of bullish analyst forecasts against the operational risk of upending the plans of eight million customers — and waiting to see whether the new tariffs will ultimately prove a margin booster or a churn accelerator.
