Ducommun Wins Multiyear Contract from Rolls-Royce for Trent 1000-TEN Aircraft Engine

Ducommun Incorporated (NYSE: DCO) (“Ducommun” or the “Company”) today announced that it has been selected by Rolls-Royce Holdings plc (LSE: RR.L) to produce complex interconnect systems for the Trent 1000-Ten engine – which will power all variants of the Boeing 787 Dreamliner. Ducommun will manufacture these products through 2022 at its operation centers in Joplin, Mo. and Guaymas, Mexico.

“We’re very proud to begin a long-term relationship with Rolls-Royce on the powerful and proven Trent 1000 engine platform for large commercial, fixed-wing aircraft,” said Anthony J. Reardon, chairman and chief executive officer. “This agreement increases Ducommun’s content on the 787 Dreamliner as well as expands our customer base with a leading jet engine OEM – a core piece of our long-term growth strategy. We look forward to working with Rolls-Royce as they play a significant part in the Dreamliner production ramp over the coming years.”

The Trent 1000-TEN engine, scheduled to be certified by the European Aviation Safety Agency (EASA) before the end of 2015, incorporates proven, next-generation technology from the latest member of the Trent engine family, the Trent XWB, to produce a superior engine for the Boeing 787 Dreamliner. It will have more thrust and efficiency, offering up to a three percent reduction in fuel consumption compared with the current Trent 1000 standard.
