Deutsche Telekom Balances Labour Strife and Defence Moves as T-Mobile US Merger Talks Heat Up

Deutsche Telekom battles a 20,000-worker wage strike while pursuing AI, defense partnerships, and a potential T-Mobile US merger that could create a $300B telecom behemoth.

A cold war is brewing at Deutsche Telekom on two fronts. At home, more than 20,000 employees have walked out in a wage dispute that shows no signs of cooling. Abroad, the company is exploring a transatlantic tie-up that would create a telecom behemoth with a market value approaching $300bn. Between them lie strategic bets on artificial intelligence and defence technology that could recast the group’s identity.

Wage Revolt Gathers Momentum

The third round of collective bargaining, held in Potsdam on 11 and 12 May, ended without a deal. Ver.di, the union representing the workforce, flatly rejected Deutsche Telekom’s initial structural offer. “It doesn’t even come close to securing real wages,” said negotiator Frank Sauerland.

Since strike action began on 28 April, some 20,000 employees have taken part in walkouts. A rally in Potsdam drew around 2,500 people, and for the first time workers from subsidiaries T-Systems and Telekom Services Europe joined the protest.

Ver.di is demanding a 6.6% salary increase over twelve months, plus an annual member bonus of €660 and an extra €120 per month in training allowances. The next — and currently final — round of talks is scheduled for 26 and 27 May. If no agreement is reached, escalation remains a real possibility.

Drones, Defence and Digital Infrastructure

While labour tensions simmer, Deutsche Telekom is pushing into unexpected territory. In May it announced a partnership with Rheinmetall to protect cities and critical infrastructure from drones and sabotage. The collaboration, unveiled ahead of the AFCEA security trade fair in Bonn, combines Rheinmetall’s sensor technology and countermeasures with Telekom’s mobile networks and digital expertise.

The focus is on drones that operate over mobile networks — a growing threat from both commercial and homemade devices. The company is also working with the Helmut Schmidt University in Hamburg on detection methods. For CEO Tim Höttges, digitalisation is a central pillar of modern defence systems. The group’s venture capital arm will invest in high-tech defence companies, reflecting a broader European trend where secure networks, cybersecurity and anti-drone capabilities are converging.

Artificial intelligence is another strategic spearhead. Deutsche Telekom has already taken stakes in Perplexity, 11labs and Lovable to accelerate technology adoption. It plans to expand its own AI factory in Germany and is in talks with Nvidia to boost computing capacity and processor utilisation.

The T-Mobile US Option

The most ambitious move, however, remains a potential merger with T-Mobile US, in which Deutsche Telekom already holds a 53% stake. Early-stage discussions envision a combined entity serving more than 200 million mobile customers, with a transatlantic footprint worth nearly $300bn.

T-Mobile US has been the group’s primary growth engine for years, and deeper integration could unlock significant synergies. Yet the regulatory hurdles are formidable. Any deal would face intense scrutiny in the United States over competition, national security and market concentration. For now, the stock market is taking a wait-and-see approach.

Financial Firepower

Deutsche Telekom’s balance sheet gives it room to pursue these ambitions. In the first quarter, organic revenue rose 4.7% to €29.9bn, driven largely by its US operations. The group raised its full-year guidance for adjusted EBITDA AL to roughly €47.5bn, up from €47.4bn, and expects free cash flow AL to exceed €19.8bn. The first quarter alone delivered adjusted EBITDA of €11.5bn.

On the domestic front, fibre adoption is improving: the FTTH connection rate climbed from 15.5% to 17.1%, with more than 13 million households now able to access the network.

Despite the solid numbers, the share price has struggled to gain momentum. The stock closed on Wednesday at €28.15, up 1.77% on the week but down 2.05% over the past 30 days. The relative strength index stood at 77.5, indicating overbought territory, while the price remained 7.31% below its 50-day moving average. Over twelve months the decline is 11.34%.

With a multi-week labour dispute unresolved and strategic options still in the exploratory phase, Deutsche Telekom’s next move may define whether operational strength translates into lasting shareholder value — or remains trapped between domestic unrest and transatlantic ambition.
