Election of Directors

On September 28, 2025, the Board of Directors (the “Board”) of Orion Group Holdings, Inc. (the “Company”) elected to increase the size of the Board from seven directors to eight directors effective November 19, 2025 and appointed Mr. Robert Ledford to fill the resulting vacancy at such time.

Mr. Ledford has served since 2019 as the President and Chief Executive Officer, and as a director, of Prime Electric, a major electrical contracting firm on the West Coast of the U.S. Mr. Ledford also currently serves as a director of Trademark Concrete, a position he has held since 2023. Prior to working at Prime Electric, Mr. Ledford held various domestic and international operations roles at AECOM (NYSE: ACM) from 2013 to 2019, including serving as Chief Operating Officer of Middle East Operations from 2013 to 2014, Global Head of Project Delivery for 2015, and Chief Operating Officer of Design and Consulting Services Americas from 2016 to 2019. Prior to joining AECOM, he worked for Parsons Corporation (NYSE: PSN) from 2005 to 2013, serving in various finance and operations roles, including Chief Financial Officer for their Civil Construction business, Chief Operating Officer for their Water and Infrastructure business, and Global Water and MENA Director of Infrastructure. Prior to joining Parsons, he served as Chief Financial Officer for over a decade at different private companies, including Sasco Electric (US West Coast) and Hermanson Corporation. He graduated from Washington State University in 1986 with a Bachelor of Arts degree, with a major in Finance and a minor in Economics.

Mr. Ledford will stand for election to the Board at our 2026 Annual Meeting of Stockholders. Mr. Ledford has not yet

been appointed to any committees of the Board. The Board has affirmatively determined that Mr. Ledford is “independent” as that term is defined by The New York Stock Exchange listing standards and the standards set forth in the Company’s Corporate Governance Guidelines. Mr. Ledford does not have a material interest in any transaction that is required to be disclosed under Item 404(a) of Regulation S-K. There is no arrangement or understanding between Mr. Ledford and any other person pursuant to which he was selected as a director. In connection with his appointment as a member of the Board, Mr. Ledford has not entered into any agreements or contracts with the Company. On November 19, 2025, Mr. Ledford will start his service on the Board and will receive a pro-rated annual equity award at that time in the form of shares of common stock of the Company consistent with that provided to other non-employee members of the Board. Mr. Ledford will also participate in the Company’s other director compensation programs on the same basis as other non-employee directors.
