Melrose Industries PLC is a United Kingdom-based pure-play aerospace manufacturing company. Operating primarily through its GKN Aerospace business, the company provides advanced aerospace components and systems to major original equipment manufacturers across both civil and defense markets. The company operates through two primary divisions: Engines and Structures. The Engines segment is a global tier-one supplier of structural engineered components, parts repair, and aftermarket services to engine OEMs. The Structures segment supplies civil and defense airframes, including lightweight composite and metallic structures, as well as electrical distribution systems. Historically known for its 'buy, improve, sell' strategy of acquiring underperforming industrial businesses, Melrose transformed into a focused aerospace entity following the 2023 demerger of its automotive and powder metallurgy divisions into the Dowlais Group. The company maintains a global manufacturing footprint with over 30 sites across multiple countries.
