TransDigm Group, Inc. (TDG) has announced an agreement to acquire Jet Parts Engineering and Victor Sierra Aviation Holdings from Vance Street Capital for approximately $2.2 billion in cash. The deal, which includes certain tax benefits, aims to enhance TransDigm’s portfolio in the commercial aviation sector.
This acquisition is expected to bolster TransDigm’s revenues, as nearly all revenues generated by the acquired companies come from the commercial aftermarket. The demand for aftermarket components is rising due to aging aircraft fleets and increased maintenance activity, resulting in a strong need for cost-efficient aftermarket solutions.
TransDigm’s growth strategy aligns with the recent trend of mergers and acquisitions in the aerospace sector, where companies are seeking to diversify their offerings amid increasing competition. Notably, TransDigm previously acquired Stellant Systems, Inc. for nearly $960 million in December 2025.
