Orion Group Holdings, Inc. was founded in 1994 as a marine construction project management business. Since then, we have expanded our reach both through organic growth and acquisitions. We have successfully acquired and fully integrated several companies into our operations, including the acquisition of T.A.S. Commercial Concrete Construction, LLC ("TAS") during 2015 and Tony Bagliore Concrete, Inc. ("TBC") during 2017. The TAS acquisition added another segment to our business, provided diversification of end market drivers and a diversified customer base. The TBC acquisition expanded the Company's current service offerings to an additional market within its concrete segment. These strategic acquisitions have also enhanced our operational capabilities, provided us with a larger geographic base, and added to our equipment fleet. Today we are focused on being the leading specialty construction company in the building, industrial, and infrastructure sectors and will continue to see growth opportunities through greenfield expansion, acquisitions, vertical integration, and diversification.
