What Melrose Industries does

Melrose Industries PLC is a UK-domiciled FTSE 100 aerospace and defence technology company (LSE: MRO), headquartered in Birmingham and operating manufacturing facilities across 12 countries. Founded in 1985 as an engineering investment vehicle, Melrose acquired GKN plc for approximately £8.1 billion in 2018 and subsequently divested its automotive businesses via the 2023 demerger of Dowlais Group for £2.9 billion, leaving a focused two-division pure-play aerospace business operating under the GKN Aerospace brand: Engines and Airframes. FY2025 revenue was £3.6 billion with an 18.0% operating margin and £647 million of operating profit; market capitalisation stood at £5.8 billion as of June 2026.

The company's product portfolio spans engine components (structural and rotating parts, parts repair services, additive fabrication), airframe structures (wing components, fuselages, empennages for civil and military aircraft), transparencies (military canopies and commercial cockpit and cabin windows using proprietary coatings), and electrical wiring interconnection systems. Core proprietary technologies include world-leading additive fabrication for flight-critical engine components, lightweight thermoplastic composites, transparent coating technology, and the H2GEAR hydrogen electric propulsion programme. The company holds 650+ patents and its components are on-board approximately 100,000 flights daily. Strategic technology positions include sole-source positions on 100% of the world's high-volume aircraft and design partner status on both the Airbus-led RISE and Pratt & Whitney GTF next-generation engine programmes.

Melrose operates a B2B Tier 1 supplier model with direct long-term contracts to a small set of major aerospace and defence OEMs, including Boeing, Airbus, Rolls-Royce, Lockheed Martin, GE Aerospace, Pratt & Whitney, Saab, Gulfstream, and HondaJet. Revenue is generated through three streams: original equipment manufacturing for new aircraft production, aftermarket services (parts repair, MRO), and 19 Risk and Revenue Sharing Partnerships (RRSPs) with engine OEMs that entitle Melrose to a share of aftermarket profits, providing $27 billion of contracted future cash flow with 85%+ of future engine profit coming from aftermarket. The company serves civil aerospace (single-aisle, widebody, business jets), defence aerospace (F-35, Gripen, Chinook, Apache, NH90), and emerging segments including space, eVTOL with Supernal, and hydrogen propulsion. Distribution is exclusively through direct enterprise relationships; there are no intermediaries or indirect channels.
