I am also delighted to have finished our board refresh with an outstanding leader like Mark”.

Mr. Caylor is a seasoned aerospace and defense executive with over 35 years of experience in driving, planning and executing corporate strategy, and identifying and capitalizing on global market opportunities that drive revenue and profitable growth. Mr. Caylor has served as a director on the board of LightPath Technologies, Inc., since October 2025 and retired as Corporate Vice President and President of Northrop Grumman’s Mission Systems Sector, a supplier of advanced sensing, processing and communications technologies for defense customers across the United States and Europe in 2024.

Mr. Caylor earned his bachelor’s degree in aeronautical and astronautical engineering from the Massachusetts Institute of Technology, and a master’s degree in aeronautics and astronautics from the California Institute of Technology. He later earned a master’s degree in business administration from UCLA’s Anderson School of Management before starting his career in 1988 at Hughes Aircraft Company, which was subsequently acquired by the Boeing Company.

Mr. Caylor commented: “It’s exciting to join Ducommun as it continues its successful transformation over the past several years by sharpening its strategic focus and reshaping its portfolio towards higher growth and margin areas. Having worked in the aerospace and defense industry for decades, I know and respect Ducommun’s well-earned reputation as a leading supplier of innovative value-added manufacturing solutions, and I am honored to join its Board of Directors. I am eager to work with Steve and the rest of the Board as they continue to execute the VISION 2027 Strategy to drive long-term value for shareholders.”

This appointment is part of Ducommun’s Board refreshment program designed to help ensure that the Company’s Board has the best mix of skills and experience necessary to support Ducommun’s leadership team in driving VISION 2027 and shareholder value. The Corporate Governance and Nominating Committee conducted a thorough search with the assistance of a leading independent search firm, who evaluated over fifty prospects for this role. This process spanned several months and culminated in Mr. Caylor being identified from among several highly qualified candidates.

Ducommun’s Board and management team have overseen a successful business transformation over the past nine years and are well positioned to continue to focus on driving sustained shareholder value through execution of the Company’s VISION 2027 Strategy.
