Spirit AeroSystems

Boeing and Airbus have completed landmark acquisitions of Spirit AeroSystems assets, fundamentally reshaping the commercial aerospace manufacturing landscape. The finalized deals, announced on December 8, 2025, represent a pivotal moment for both manufacturers and signal the end of Spirit’s tenure as an independent aerostructures supplier. Boeing’s Comprehensive Integration Boeing confirmed the acquisition of all Spirit-related commercial operations, including fuselages for the 737 program and major structures for the 767, 777, and 787 Dreamliner. The deal also encompasses commercially procured fuselages for military platforms including the P-8 and KC-46. Notably, the transaction brings Spirit’s extensive spare-parts business in-house, significantly expanding Boeing’s maintenance, repair, and overhaul (MRO) capabilities and strengthening its aftermarket portfolio.

The Federal Trade Commission has issued a landmark decision that could reshape Boeing’s acquisition of Spirit AeroSystems, requiring the aerospace giant to divest critical manufacturing operations to address competitive concerns. Under the consent order announced December 3, 2025, Boeing must sell Spirit’s aerostructures business in Subang, Malaysia to Composites Technology Research Malaysia (CTRM), along with all associated assets and personnel. The $8.3 billion acquisition, which Boeing announced in July 2024, aimed to reintegrate its former parts supplier and bring significant manufacturing in-house. Spirit AeroSystems is among the world’s largest producers of fuselages, wings, and aerostructures, supplying approximately 70% of the structural components for Boeing’s 737 series while also providing critical parts to competitor Airbus.
