Spirit AeroSystems Overview

About Spirit AeroSystems

Spirit AeroSystems is an aerostructures manufacturer headquartered in Wichita, Kansas, and one of the world's largest makers of commercial aircraft fuselages and structures. It builds the complete fuselage of the Boeing 737, major structures for the 767, 777 and 787, and fuselages for the military P-8 and KC-46, and also supplies aftermarket parts and repairs. Spirit earns revenue from long-term supply contracts, chiefly with Boeing, and reported revenue of USD 6.05 billion in 2023. The company was formed in June 2005 when Onex bought Boeing's commercial aircraft operations in Wichita, Kansas and in Oklahoma, and it listed on the New York Stock Exchange in 2006. Boeing agreed in July 2024 to buy Spirit back for about USD 4.7 billion in equity, or USD 8.3 billion including debt, and completed the acquisition in December 2025, when Spirit's Airbus-related operations passed to Airbus and its Belfast business became a Boeing subsidiary branded Short Brothers. Its Wichita, Dallas and Tulsa plants and its Prestwick innovation centre, with about 15,000 employees, were integrated into Boeing.

Spirit AeroSystems Acquisition

Spirit AeroSystems was acquired by Boeing for $8.3B on 1 July 2024.

The acquisition price implies a 1.3x revenue multiple on $6.3B of revenue.

Spirit AeroSystems, a leading aerostructures manufacturer based in Wichita, Kansas, produces fuselages for Boeing's 737 program and major structures for the 767, 777, and 787 Dreamliner programs, along with fuselages for the P-8 and KC-46, and operates facilities in Wichita, Dallas, Tulsa, Prestwick in Scotland, and Belfast in Ireland. Boeing, a major aerospace company, announced on July 1, 2024, a definitive agreement to acquire Spirit in an all-stock transaction valued at $4.7 billion equity or $8.3 billion enterprise value, equating to $37.25 per share—a 30% premium over Spirit's February 29, 2024, closing price of $28.60. The strategic rationale focuses on reintegrating Spirit to align commercial production systems, safety and quality management, engineering, and manufacturing capabilities, while improving supply chain stability, aviation safety, and continuity for U.S. defense programs; Spirit's defense operations will continue independently as Spirit Defense. The deal required Spirit to divest Airbus-related commercial work packages via a term sheet with Airbus for asset transfer, approved alongside the merger by Spirit's board and nearly 78 million shareholders in early 2025. Subject to regulatory approvals and customary conditions, the transaction closed on December 8, 2025, bringing Spirit's 15,000 employees and Boeing-related commercial, aftermarket, and defense operations under Boeing, with aftermarket aligning under Global Services and Belfast operations forming an independent subsidiary named Short Brothers. This acquisition addresses Boeing's production challenges post-737 MAX issues by internalizing its largest supplier, enhancing maintenance, repair, and overhaul capabilities, and stabilizing workforce across key U.S. sites amid ongoing financial pressures, as Spirit reported a $2.1 billion loss in 2024.
