Orion Group Holdings, Inc. (the “Company”) previously filed a Current Report on Form 8-K on September 28, 2023 to report that the Company had entered into an Employment Agreement with Mr. Travis J. Boone, effective September 27, 2023 (the “Boone Employment Agreement”), pursuant to which he has served as the President and Chief Executive Officer of the Company. The Company separately filed a Quarterly Report on Form 10-Q on April 26, 2024 that reported, among other things, that the Company had entered into an Employment Agreement with Mr. E. Chipman Earle, effective March 20, 2024 (the “Earle Employment Agreement,” and together with the Boone Employment Agreement, the “Executive Employment Agreements”), pursuant to which he has served as Executive Vice President, General Counsel, Chief Administrative Officer, Chief Compliance Officer and Corporate Secretary of the Company. Each of the Executive Employment Agreements was scheduled to expire pursuant to its terms on September 19, 2026. On September 18, 2026, the Company and each of Messrs. Boone and Earle entered into separate amendments which effectively extend the initial term of the Executive Employment Agreements to December 31, 2026, and provide for automatic annual extensions commencing January 1, 2027 (together, the “Amendments”). No other terms of the Executive Employment Agreements were impacted by the Amendments.
