Airbus and Boeing finalize acquisition of Spirit AeroSystems Belfast operations

The landmark acquisition of Spirit AeroSystems' operations in Belfast, Northern Ireland, by aerospace giants Airbus and Boeing has officially concluded. This strategic transaction, finalized on December 9, 2025, marks a significant restructuring of a key aerospace manufacturing hub and secures critical production capabilities for both original equipment manufacturers (OEMs). The deal's completion follows extensive negotiations and regulatory approvals, aiming to streamline supply chains and enhance operational control over essential aircraft components.

Under the terms of the agreement, the portion of the Belfast facility responsible for manufacturing wings and mid-fuselage sections for the Airbus A220 aircraft program will be integrated directly into Airbus's global production network. This segment will now operate as 'Airbus Belfast,' ensuring the continued, dedicated supply of these crucial components for the rapidly growing A220 fleet. This move allows Airbus to bring a vital part of its A220 supply chain in-house, potentially improving efficiency and reducing reliance on external suppliers for this specific program.

The remaining operations at the Belfast site, which primarily support Boeing aircraft programs, have been transferred to Boeing. This ensures that the production of components for Boeing's commercial aircraft, previously handled by Spirit AeroSystems, will now fall under Boeing's direct management or a newly established entity controlled by the US manufacturer. This dual acquisition reflects a broader industry trend where OEMs are increasingly seeking to exert greater control over their critical suppliers, especially for complex aerostructures.

For Spirit AeroSystems, the divestiture of its Belfast operations represents a significant step in its ongoing strategic review and portfolio optimization efforts. While the full financial details were not disclosed, the transaction is expected to allow Spirit to focus on its core competencies and other strategic initiatives, potentially strengthening its balance sheet and operational focus. The move is anticipated to have long-term implications for the aerospace manufacturing landscape in Northern Ireland, solidifying its role within the supply chains of two of the world's largest aircraft producers.
