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 loss of $612.9 million on Thursday in its first quarter of 2025. The company also said on Friday it will be temporarily laying off 250-350 workers, beginning May 12.
