SRA International, Inc. to Acquire Constella Group, LLC

FAIRFAX, Va., June 20 /PRNewswire-FirstCall/ -- SRA International, Inc. (NYSE: SRX), a leading provider of technology and strategic consulting services and solutions to federal government organizations, today announced the signing of a definitive agreement to acquire Constella Group, LLC, a privately-held provider of global health consulting services.

Headquartered in Durham, NC, Constella employs more than 1,500 professionals organized by three interrelated service offerings: domestic health sciences, international health development and global drug development. The domestic health sciences business provides research, technology, communications and strategy support to U.S. government agencies charged with protecting and advancing the health of their constituents. Constella's international health development business helps emerging nations across the world create and implement health policy, primarily through contracts with the governments of the U.S. and the United Kingdom. The global drug development business provides blue-chip pharmaceutical, biotechnology and medical device firms with the strategic insight and services needed to take a drug, biologic or device through the development process from concept to market. The company's combination of capabilities, domain expertise and geographic reach enable it to offer differentiated solutions to address the world's most complex health issues. Constella acquired two companies during calendar year 2006. Excluding pre-acquisition revenue for those two companies, Constella revenue for calendar year 2006 was approximately $169 million.

SRA President and CEO Stan Sloane said, "Constella's deep domain expertise, combined with the capabilities of our existing health business, will offer a comprehensive solution in the global health marketplace. We're delighted to welcome Constella's employees and customers to SRA. They will form the foundation of a new health business unit to be led by Don Holzworth, which will bring even greater focus to this growing market in the future."

Commenting on the sale, Constella's founder and CEO Donald Holzworth added, "We've worked with SRA for many years and have high respect for their management and culture. Our companies were both built on a powerful vision, and we look forward to significant opportunities for growth and expansion together."

SRA Executive Vice President and Chief Financial Officer Stephen Hughes stated, "Constella's health market credentials address a key element of our long-term strategy. We expect this transaction to be accretive to earnings in Fiscal Year 2008, with significant cash tax benefits. We believe the strength and stability of our cash flows provide ample borrowing capacity to make further acquisitions in the near term."

Completion of the transaction is subject to customary closing conditions and the Hart-Scott-Rodino waiting period, and closing is expected within approximately one month. William Blair & Company, LLC acted as the exclusive advisor to Constella Group in this transaction.
