UK Regulator Reviews Boeing-Spirit AeroSystems Deal for Competition Concerns

Spirit AeroSystems

CMA begins assessment of Boeing’s acquisition

The UK Competition and Markets Authority (CMA) has opened an information-gathering phase into Boeing’s acquisition of Spirit AeroSystems. The CMA is inviting comments from stakeholders until 15 July to determine whether the deal could significantly reduce competition in the UK aerospace supply chain. Boeing agreed to acquire Spirit in July 2024, while Airbus secured a parallel agreement to take over Spirit’s facilities tied to Airbus programmes.

Implications for Airbus and UK facilities

Spirit AeroSystems operates two major UK plants, in Prestwick, Scotland, and Belfast, Northern Ireland. These sites manufacture key wing structures for Airbus’ A320, A350, and A220 models. Airbus is set to acquire both sites as part of its agreement with Spirit, along with production of A220 mid-fuselage sections in Belfast if no alternative buyer is found. This parallel arrangement ensures Airbus retains access to strategic UK-based component production, even as Boeing consolidates Spirit’s broader operations.

The CMA has jurisdiction over foreign acquisitions with material UK impact. It can intervene if a target has UK turnover exceeding £100mn, if the merged firms will supply more than 25pc of a UK product market, or if one firm has turnover above £350mn and a significant UK supply share. Spirit’s UK presence clearly meets these thresholds.

Strategic and competitive outlook

While the CMA’s initial inquiry focuses on Boeing’s acquisition, it has not confirmed whether Airbus’ parallel acquisition of UK operations will also fall under review. The CMA’s assessment could shape future aerospace industrial policy, especially as Boeing and Airbus dominate global aircraft production and compete closely across supply chains. Any ruling will influence the structure of UK aerospace manufacturing and its integration into transatlantic aircraft programmes.

The Metalnomist Commentary

The CMA’s review underscores the strategic importance of Spirit’s UK operations for both Boeing and Airbus. If the deal proceeds without remedies, it may consolidate power within the duopoly but also ensure stability of critical aerospace supply lines. The decision will likely balance competition with national industrial resilience.
