Elliott Management Opens Multi-Billion Telecom Campaign, Targets Deutsche Telekom and T-Mobile Parent

Elliott Management has disclosed stakes in both Deutsche Telekom and its U.S. subsidiary T-Mobile, opening a rare two-tier activist campaign that reaches across the Atlantic telecom hierarchy. The New York-based fund now holds positions worth an estimated $2.5 billion combined, according to filings parsed Wednesday, and is publicly calling for Deutsche Telekom to abandon merger speculation while demanding a strategic review of its European footprint.

Deutsche Telekom shares in Frankfurt rose 3.2% on the disclosure, while T-Mobile US gained 1.8% in New York trading. Elliott's letter to Deutsche Telekom's supervisory board, dated May 14, urges the parent to monetize legacy assets in Poland and the Netherlands and to stop entertaining cross-border merger discussions that would dilute its 48.4% economic interest in T-Mobile. Separately, Elliott is pressing T-Mobile management to resist any strategic combination with its German parent, arguing that U.S. wireless margins justify standalone premium valuation. The dual-front structure is uncommon: activist funds typically choose one entity in a parent-subsidiary relationship to avoid conflicts, but Elliott is treating the telecom value chain as a single broken capital allocation story.

The timing matters because Deutsche Telekom has spent eighteen months in quiet talks with Orange and Telefónica over potential European consolidation, discussions that stalled in March but never formally ended. Elliott's entry kills that optionality. The fund's thesis is straightforward: Deutsche Telekom trades at 8.2x forward EBITDA while T-Mobile trades at 10.1x, a gap that persists because the parent's European operations drag down the multiple and because management has signaled willingness to use T-Mobile equity as M&A currency. Elliott wants Deutsche Telekom to divest non-core European assets, buyback its own stock, and treat T-Mobile as a passive cash-generating stake rather than a strategic chess piece. For T-Mobile, the ask is simpler—ignore the parent, keep buying back shares, and avoid any transaction that would re-introduce Deutsche Telekom operational influence.

This is a capital structure argument dressed as activism. Deutsche Telekom's market cap is €112 billion; its T-Mobile stake alone is worth roughly €95 billion at current prices. The parent's enterprise value implies the European business is worth nearly nothing after netting out the U.S. asset, a valuation Elliott argues is both accurate and fixable. The fund has not yet filed a 13D in the U.S., suggesting its T-Mobile position may sit just below the 5% disclosure threshold, but the Deutsche Telekom stake is confirmed above 1% of shares outstanding. The board pressure is immediate: Elliott has requested seats on Deutsche Telekom's supervisory board and is scheduling meetings with T-Mobile's independent directors in the next thirty days.

Allocators should watch for three follow-on moves. First, whether Deutsche Telekom announces asset sale processes in Poland or the Netherlands by mid-June, which would confirm management is negotiating rather than resisting. Second, whether T-Mobile accelerates its buyback authorization, currently $19 billion remaining, in the August earnings call. Third, whether Elliott expands its telecom book beyond these two names—filing patterns suggest the fund has been accumulating positions across the European telecom sector since March, and additional disclosures could surface in the next two weeks as 13F and European transparency deadlines converge.

The campaign structure tells you Elliott believes the mispricing is permanent without intervention. The fund does not build positions in parent and subsidiary simultaneously unless it expects management to actively destroy value through consolidation. That expectation is now public, and the clock is running.
