Airbus faces challenges as engine supply strains lead to production delays and profit forecast reductions. CFM International's struggles to meet demands from Airbus and Boeing result in an 11% drop in Airbus's share price. Negotiations between Airbus and CFM to increase A320neo engine deliveries stalled, impacting the aerospace sector's stability. Additionally, Airbus is poised to take over operations of four Spirit AeroSystems plants, including crucial facilities in North Carolina, Northern Ireland, Morocco, and France, as part of a deal with Boeing. Airbus CEO cites engine supply shortages and uncertainties with Spirit AeroSystems as reasons for cutting output forecasts and hints at an imminent acquisition of Spirit's assets related to A350 and A220 programs.
