What Spirit Aerosystems does

Spirit AeroSystems is one of the largest independent (pre-acquisition) non-OEM designers and manufacturers of aerostructures for the global commercial and defense aerospace industry. The company designs, develops, and manufactures complex primary and secondary structures, including nacelles, pylons, fuselages, wings, wing-to-body fairings, thrust reversers, and control surfaces, supplied as Tier 1 hardware to Boeing and Airbus. Core platforms supported include the Boeing 737 MAX, 767, 777, 787 Dreamliner, defense platforms, and the Airbus A220, A320neo family, A321, and A350. Spirit also provides MRO services for aerostructure components through its Global Customer Support and Services division and operates Spirit Defense, a non-integrated subsidiary that serves defense prime contractors including Northrop Grumman.

The company's revenue model is a B2B contract-manufacturing model with long-term supply agreements to two anchor OEMs, and pricing is negotiated, non-public, and tied to multi-year program commitments. Spirit held a global manufacturing footprint spanning Wichita, Tulsa, Dallas, and Kinston (US); Prestwick and Belfast (UK); Saint-Nazaire (France); Casablanca (Morocco); Subang (Malaysia); and a composite materials joint venture in Jinjiang, China. Technology capabilities center on advanced composite and metallic aerostructure manufacturing, supported by NADCAP, AS9100, ISO 9001/14001/45001, FAA, and EASA certifications. Spirit has initiated AI-assisted inspection and digital-twin manufacturing initiatives in collaboration with national laboratories and universities, with reported but modest productivity gains.

On December 8, 2025, Boeing completed an all-stock acquisition of Spirit valued at approximately $4.7B in equity (~$8.3B total enterprise value including ~$3.6B of absorbed Spirit debt). Concurrently, Airbus acquired Spirit's Airbus-dedicated industrial assets (Kinston, Saint-Nazaire, Casablanca, Belfast A220 work, and Prestwick work) for $439M, effectively partitioning Spirit along OEM customer lines. Spirit Defense and the Short Brothers brand in Belfast were retained within Boeing. The FTC finalized its consent order in February 2026, requiring divestitures, information firewalls, and an independent monitor. Post-acquisition, Spirit operates as a wholly-owned Boeing subsidiary and is no longer independently reporting financials.
