About
CACI International is a defense and federal IT company founded in 1962 and headquartered in Reston, Virginia, trading on the NYSE under ticker CACI.

The company is frequently named to Washington Technology's Top 100 Government Contractors list and has a strong competitive position in contested-environment warfare systems—a direct beneficiary of DoD's increased spending on multi-domain operations and spectrum warfare.
