T-Mobile US stock gains as Elliott pressure on Deutsche Telekom reshapes merger debate

T-Mobile US stock has moved higher after reports that activist investor Elliott wants parent Deutsche Telekom to abandon a potential USD 300 billion merger structure, reinforcing expectations for continued buybacks while the core U.S. business delivers double-digit revenue growth.

T-Mobile US stock (ISIN US8725901040) has attracted fresh attention after activist Elliott Investment Management reportedly pushed parent company Deutsche Telekom to drop ideas for a potential USD 300 billion full merger structure, while the U.S. carrier continues to post double-digit revenue growth in 2026 and its share price climbs toward its recent high of 187.30 USD as of September 2, 2026, according to data cited by Investing.com.

Elliott challenges merger ideas and backs buybacks

According to the report summarized by Investing.com on September 3, 2026, Elliott Investment Management has built a sizeable stake in Deutsche Telekom and is urging the German group to abandon a potential full merger of Deutsche Telekom and T-Mobile US valued at around USD 300 billion in favor of larger share buybacks at the parent.

The same article notes that T-Mobile US shares closed at 187.30 USD on September 2, 2026, up 2.8% on the day, while Deutsche Telekom shares also gained, underlining that equity investors broadly welcomed the focus on capital returns and a clearer ownership structure for the U.S. business.

Stock performance and valuation signals for T-Mobile US

Market data cited by Investing.com show that T-Mobile US closed at 187.30 USD on September 2, 2026, which represented a 2.8% gain on that day and leaves the stock roughly 10.3% lower year to date compared with the start of 2026, while a separate overview from Zacks highlights that AT and T is up 4.7% and Verizon is up 23.5% over the same period.

This means that despite the strong absolute level of 187.30 USD, T-Mobile US has underperformed its two main U.S. wireless peers in 2026 by around 15 to 20 percentage points year to date, an underperformance that helps explain why an activist sees scope for value creation at the Deutsche Telekom and T-Mobile US equity complex.

Operating momentum and recent financial figures

In its most recent reported quarter, T-Mobile US highlighted continued growth in the core U.S. wireless business, with external summaries of the latest earnings season pointing to double-digit percentage revenue growth versus the comparable period of the prior year and stable profitability levels for the U.S. carrier in the first half of 2026; while individual line items vary by source, the consistent picture is of a company that is expanding its service revenue faster than many peers and maintaining a solid margin profile in 2026.

Compared with historical results from fiscal year 2023, when the company was still integrating earlier acquisitions, the current 2026 run rate implies a noticeably higher revenue base and a larger customer footprint, underlining that the fundamental story of T-Mobile US is one of scaling up its 5G network and monetizing higher usage and premium tariff plans.

DACH angle via Deutsche Telekom listing

For investors in the DACH region, the Elliott intervention matters because T-Mobile US is majority owned by Deutsche Telekom, which is listed in Frankfurt and on platforms such as Xetra and Tradegate; according to a Tradegate-based indication compiled by MarketScreener on September 3, 2026, Deutsche Telekom shares were recently quoted around 29.02 EUR, around 5.03% higher than at the start of 2026.

This link means that part of the value created at T-Mobile US flows into German and European portfolios via Deutsche Telekom, and activist pressure on the parent company to optimize the T-Mobile US stake and capital allocation could therefore influence both the New York quoted T-Mobile US stock and the Frankfurt traded Deutsche Telekom stock in parallel.

5G network and mobile plans as key product drivers

A central product pillar for T-Mobile US in 2026 is its 5G mobile service portfolio, which includes postpaid and prepaid plans targeted at consumers and business customers across the United States, supported by nationwide 5G coverage and bundled offers that combine mobile data, voice and additional services such as streaming partnerships.

The company also markets home internet access based on 5G fixed wireless technology, using its mobile network to offer broadband access in areas where cable or fiber connections are limited, and has highlighted in recent presentations, including notices about upcoming investor conferences on September 2026 published via its own investor conference announcements, that this product category is an incremental growth area alongside traditional mobile revenue.
