CACI Named to GI Jobs Top 100 Military-Friendly Employers

Company Places 31st for Excellence in Supporting Military Personnel Transitioning to Civilian Employment

Arlington, VA, November 12, 2009 - CACI International Inc (NYSE:CACI) announced today that it has placed 31st in GI Jobs magazine's Top 100 military-friendly employers, up from 36th last year. The award honors the company's outstanding support for hiring former military and Guard/Reserve personnel.

GI Jobs magazine is the premier publication for military transitioning to civilian employment, providing education, transition assistance, and job opportunities. Companies are chosen to the Top 100 in recognition of their level of dedication to military hiring, observance of Reserve/Guard policies, percentage of new veteran hires, veteran training programs, and previous years' rankings.

CACI participates in many military-friendly recruitment opportunities and devotes a special section of its recruiting website (http://www.caci.com/careers.shtml) to military hiring. The company provides meaningful careers for veterans with disabilities through its Deploying Talent - Creating Careers program and works with the Department of Labor on the Hire Vets First initiative. Its support for Guard/Reserve employees was recognized in 2008 with the Employer Support of the Guard and Reserve's "Above and Beyond" award.

CACI also provides funds and volunteers to help the United Service Organization (USO), and President of U.S. Operations Bill Fairl sits on the USO-Metropolitan Washington board of directors. CACI is a co-founding sponsor of Cause (Comfort for America's Uniformed Services), a nonprofit organization that helps warfighters recuperating from wounds and injuries. The company has supported the Special Operations Warrior Foundation, which helps the surviving children of lost military personnel, Walter Reed Hospital, and the Fisher House program, which provides housing to family members of hospitalized serviceman and women.

Bill Fairl, President of U.S. Operations, said, "For CACI, recruiting and hiring veterans and Reserve/Guard employees is good business. We have a constant demand for top-notch talent, and former military professionals fill the bill. They understand our client base, are highly motivated, and bring solid skills and experience to the job. We're enhancing our competitive position by recruiting from this superb talent pool."

According to President and CEO Paul Cofoni, "CACI is proud to be named a GI Jobs Military-Friendly Employer for the second year in a row and even more gratified that we're able to assist veterans in finding meaningful, rewarding careers. These individuals are dedicated to their mission, have a strong work ethic, and have a unique perspective on the requirements of our DoD clients. As long as our company serves national missions, CACI will be seeking to hire those who served our nation."
