The Linde Shadow: Deutsche Telekom's Stock Rout Deepens as M&A Blueprint Spooks Investors

Stock falls 22% from high after WSJ report of T-Mobile US merger plan; World Cup viewership and labor deal ignored as market focuses on uncertainty.

It took just one report from the Wall Street Journal to knock Deutsche Telekom's stock into a tailspin. Since June 11, when the paper outlined a plan for a multinational holding company that could merge the Bonn-based group with its US-listed majority stake T?Mobile US, the shares have slid more than 22% from their 52?week high. At €26.72, the equity is barely above its yearly low of €25.99 and trades almost 8% below the 200?day moving average — a clear technical warning.

The proposed structure, modelled on the Linde?Praxair merger, calls for a double listing in the US and Europe. T?Mobile US already contributes roughly two?thirds of group revenue, and a combined entity would dilute the influence of German shareholders further. Chief Executive Timotheus Höttges has refused to comment on the speculation, and the German government, a significant stakeholder, dismissed the reports as “rumour”. Any formal offer would require regulatory clearances in both Germany and the US, a process that could drag on for months or even years. Höttges also needs the backing of T?Mobile US minority investors and political approval from Berlin — both uncertain.

That merger overhang has overwhelmed a raft of positive operational news. The exclusive broadcast rights for the 2026 FIFA World Cup have driven record viewership on the MagentaTV platform. In the first seven days of the tournament, more than 36 million people tuned in; the France?Senegal match peaked at 6.5 million concurrent viewers. During the German national team’s opening game, data traffic for MagentaTV alone hit 14,700 Gbps. Subscription sales have more than doubled compared with the 2024 European Championship.

Away from the pitch, the labour front has also stabilised. The ver.di union has approved a new collective agreement covering around 60,000 staff. The deal delivers an 8.5% pay increase spread over 33 months and rules out compulsory redundancies until the end of 2028. The end of weeks of walkouts removes a recurring headache for management.

Meanwhile, the share buyback programme — the second tranche of up to €550 million runs to the end of June as part of a €2 billion scheme through 2026 — has done little to prop up the stock. Since April 2, the company has bought back 15.3 million shares, most of which are earmarked for cancellation. The market has yawned.

The underlying business data, however, paints a resilient picture. First?quarter 2026 revenue rose 4.7% organically to €29.9 billion, and adjusted EBITDA AL climbed 7.5%. Management raised the full?year targets: adjusted EBITDA AL is now expected at around €47.5 billion, with free cash flow AL above €19.8 billion. The 2025 dividend of €1.00 per share, up 11% year?on?year, yields a robust return at current price levels — yet the shares have ignored it.

The market’s focus remains fixed on the merger uncertainty. The stock’s worst weekly performance since late April — a drop of more than 3% in the week after the WSJ report — echoed an earlier Bloomberg story in April that first flagged merger talks. With the next set of results due on August 6, investors will get their first hard look at the financial impact of the World Cup bonanza. Until Berlin signals whether it is willing to bless a deal, the merger fog shows no sign of lifting.
