Rheinmetall AG is reconsidering its plans to acquire German Naval Yards Kiel (GNYK), a move that would significantly alter the landscape of European defense consolidation.

The company indicated it may withdraw from the transaction following mounting concerns that the German government could cancel the billion-euro F126 frigate program, which was the primary strategic rationale for the acquisition.

The stock dropped approximately 16% in early trading on Thursday and fell another 13% on Tuesday, reflecting investor anxiety over the potential loss of a major revenue stream and the strategic value of the GNYK asset.

Rheinmetall stated that it had only submitted a non-binding offer for the Kiel-based shipyard, leaving the door open to exit the deal without significant penalty.

This development comes as the defense sector faces heightened scrutiny over large-scale naval projects, with political and budgetary pressures intensifying in Berlin.

The news adds to a week of severe volatility for Rheinmetall shares, which have already suffered steep declines amid fears that the F126 program might be scrapped.
