Spirit AeroSystems said there is "substantial doubt about the company's ability to continue as a going concern" though Boeing and Airbus are planning to acquire portions of the parts maker.

Spirit AeroSystems, a key Boeing supplier, is temporarily laying off workers on its 737 production line to manage an inventory surplus, the company said Friday.

Spirit AeroSystems reported a drop in revenue for Q1 2025 mainly due to reduced production on most Boeing programs, especially the Boeing 737.
