Hedge fund Elliott builds stake in Deutsche Telekom and opposes merger with T-Mobile US, sources say

Elliott is one of the most experienced activist investors in the world and is known for buying significant stakes in companies to push strategic changes. At Telekom, headed by Tim Höttges, who will turn 64 in a few days, such a campaign would directly target the strategic direction of the Dax-listed company.

Deutsche Telekom holds a majority stake in T-Mobile US, the second-largest US mobile operator, which has gained significant value in recent years. Proponents of a merger point to the ability to consolidate control and simplify structures. Opponents, however, warn of dilution, higher costs, and dependence on an already volatile US market.

Strategic debate over T-Mobile US

The exact terms of a possible campaign remain open. The sources added that Elliott is seeking dialogue with management and the supervisory board before potentially taking formal steps at the next annual general meeting. Political support would thus be needed, for example, from the German federal government, which holds an indirect stake in Telekom through the KfW banking group.

The timing of the stakebuilding comes amid an already tense monetary policy environment. An interest rate hike by the European Central Bank next week is considered likely by market participants; at the same time, more observers expect an increase in US key interest rates by the Federal Reserve following Fed Chair Kevin Warsh's remarks the previous Friday, which were viewed as restrictive.

Monetary policy as backdrop

Deutsche Telekom's stock showed slight price movements on the day of the reporting, without a clear trend being discernible. Analysts pointed out that the engagement of an activist investor creates short-term uncertainty but could also serve as a corrective for corporate strategy over the medium term. No statement from the German government was initially available.

Observers see the move as a signal to the company's management not to put at risk the strategic independence of T-Mobile US and the associated corporate value through a merger. In comparable cases, such as at AT&T or at the energy company Phillips 66, Elliott has pushed for a change of course through public letters and alternative proposals. No formal request for an extraordinary general meeting has been filed so far.

The developments are likely to attract attention at the European level in the coming weeks as well, as a possible merger would have implications for digital sovereignty and the availability of mobile spectrum. Deutsche Telekom referred to its usual communication channels for further details and announced it would comment at the appropriate time.

Outlook: Talks rather than confrontation

Overall, it remains to be seen how the supervisory board, management, and political stakeholders will position themselves. At the same time, the sources said the hedge fund is open to talks and is seeking a constructive dialogue to find a sustainable long-term solution for the group's structure. The outcome of the current contest of strength therefore remains open for now.

The coming weeks are seen as crucial to observe whether Elliott will expand its stake further and whether management will send initial strategic signals regarding T-Mobile US. Should the pressure intensify, the question of a merger could be taken off the table once and for all — or it could end up on the agenda of the next ordinary annual general meeting.
