Springfield, VA – September 3, 2013, – Versar, Inc. (NYSE MKT: VSR) announced today it has acquired Geo-Marine, Inc., a business with more than $20 million in annual revenues. The purchase price was paid with a combination of cash and seller notes. Geo-Marine, headquartered in Plano, Texas, provides engineering design, construction management, environmental planning and programming, and other services in support of a wide range of government, industry, and commercial clients. Key long-term clients include the U.S. Navy, the U.S. Air Force and the U.S. Army Corps of Engineers.

Geo-Marine is expected to be accretive to earnings in year one and adds contracted backlog of over $15 million.

Tony Otten, CEO of Versar said, “Geo-Marine is a great strategic fit for Versar. Our cultures are similar and Geo-Marine’s technical capabilities complement our own very well. In particular, Geo-Marine’s environmental expertise and customer base will allow us to expand our reach in terms of clients, technical capabilities and geography.”

“Of particular note,” Mr. Otten continued, “is Geo-Marine’s long-term relationship with the U.S. Navy. Just this past July, they were selected, along with two other firms, for a new, $75 million five-year ID/IQ with NAVFAC. We have identified the U.S. Navy as a key market that Versar wanted to penetrate, and with the acquisition of Geo-Marine, we believe we have accomplished that. We look forward to providing the U.S. Navy the same high-quality service that we have provided other branches of DOD.”
