In the OEM segment, the company develops and manufactures engine modules, components, and parts, often in collaboration with major industry partners like Pratt & Whitney, General Electric, and Rolls-Royce. The MRO segment provides comprehensive lifecycle support, maintenance, and repair services for commercial aircraft engines and industrial gas turbines. MTU's components are featured in prominent aircraft programs, including the Airbus A320neo, Boeing 787, and the Eurofighter Typhoon. With a global footprint spanning Europe, North America, and Asia, the company benefits significantly from recurring revenue streams generated by its aftermarket services.
