Orion Group Holdings Inc

Our corporate headquarters is currently located at 12000 Aerospace Avenue, Suite 300, Houston, Texas 77034, with 21,480 square feet of office space that we lease, with a current term expiring July 31, 2025 and with one five-year extension at our option. Our executive, legal, finance, and some accounting offices are located at this facility. In the summer of 2025, we are scheduled to relocate our corporate headquarters and consolidate our other operations offices in the greater Houston area to a new location at 2940 Riverby Road, Houston, Texas 77020. The lease for the new corporate headquarters and operations offices includes approximately 63,500 square feet of office space with a term expiring in 2036, subject to two five-year extensions at our option.

We lease office space in Alaska, Hawaii, Louisiana, Florida, Texas and Washington for our operations, including office and yard space. We may lease smaller project-related offices throughout our operating areas when the need arises.

We believe that our existing facilities are adequate for our operations. We do not believe that any single facility is material to our operations and, if necessary, we could readily obtain a replacement facility. Some of our real estate assets are pledged to secure our Credit Agreement.
