CACI, founded in the early 1960s as California Analysis Center Inc., is almost entirely a Beltway Bandit—some 94 percent of its revenue is derived from contracts with the U.S. government. About two-thirds of that revenue comes from the Pentagon, but CACI also enjoys the patronage of the Departments of Homeland Security, State, Commerce, Justice and Transportation. At the end of its last fiscal year, CACI had a contract backlog worth some $6.4 billion.
