Primoris Services Corporation Joins Russell 2000(r) Index


LAKE FOREST, Calif., June 30, 2009 (GLOBE NEWSWIRE) -- Primoris Services Corporation (Nasdaq:PRIM) (Nasdaq:PRIMU) (Nasdaq:PRIMW) ("Primoris" or "Company"), one of the largest specialty contractors and engineering companies in the United States, today announced that it was added to the Russell 3000(r) Index and the subset Russell 2000(r) Index. Primoris' inclusion became effective upon the close of trading on Friday, June 26, 2009 following the Russell Investment Group's annual reconstitution of these lists. Primoris was also added to the Russell Microcap(r) Index and Russell Global(r) Index.

Brian Pratt, Chairman, President and Chief Executive Officer of Primoris, commented, "Our inclusion in the Russell 2000 less than one year after becoming a public company evidences our continued development and reflects the success of our industry expansion efforts. We expect that being part of the Russell 2000 will serve to further elevate and broaden our profile among those investors who utilize the Russell indexes in making their investment decisions."

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $4 trillion in assets currently are benchmarked to them. These investment tools originated from Russell's multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers.
