DCO Ducommun Inc

Ducommun Incorporated (NYSE: DCO) (“Ducommun” or the “Company”), a global supplier of innovative electronic and structural solutions for the aerospace & defense industry, is proud to announce that it has earned the Northrop Grumman Mission Systems (“NGMS”) Platinum Supplier Designation. The designation recognizes Ducommun’s continuous high level of quality and on-time delivery performance in providing micro power supplies to ground-based radar systems used to eliminate missile threats to the warfighter. The micro power supplies are produced at Ducommun’s world-class circuit card assembly engineering and manufacturing performance center in Tulsa, Oklahoma.

“We are thrilled to have met and exceeded quality and delivery requirements for this strategic program by providing the highest level of value for Northrop Grumman Mission’s Systems along with continuing to build out our radar business for Ducommun’s defense customers. This designation is another step forward in our developing relationship with Northrup Grumman for new applications along with off-loading opportunities in the future. Our Tulsa business now moves more and more into radar systems, complementing its already significant circuit card assembly business for missiles” said Stephen G. Oswald, chairman, president, and chief executive officer.

“The other great news is this is our third OEM Customer award over the past the past six weeks with the other two being the 2023 Supplier of the Year from Gulfstream and the 2023 Elite Supplier Award from Lockheed Martin. Again, this proves that everyone here at Ducommun is focused and relentless on quality, on-time delivery, providing significant value to all stakeholders and achieving the Vision 2027 goals”.

With the Platinum Supplier Designation, the Company is well positioned to competitively win as a top value provider and further support off-loading from its strategic defense customers, which is expected to benefit shareholders for years to come. Ducommun currently provides NGMS with leading defense products on both legacy and emerging programs.
