Spirit AeroSystems Holdings, Inc. is an American manufacturer of aerostructures for commercial airplanes, headquartered in Wichita, Kansas. The company produces fuselage sections for Boeing's 737 and 787 aircraft, as well as the flight deck sections for a majority of Boeing airliners. Spirit also supplies Airbus with fuselage sections and front wing spars for the A350 and wings for the A220. Spirit's primary competitors in the aerostructures market include Collins Aerospace, Kawasaki Heavy Industries, Leonardo, and Triumph Group. Spirit AeroSystems was established in 2005 when Boeing spun-off its Wichita division to an investment firm. Boeing entered into an agreement to re-acquire Spirit in July 2024 for $4.7 billion. Concurrently with the planned closing of the Boeing acquisition, expected in the third quarter of 2025, Spirit will transfer specific assets involved in Airbus production directly to Airbus under a definitive agreement announced in April 2025. Both transactions are subject to regulatory approvals and other closing conditions. Wikipedia
