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. With annual revenues in the $6–7 billion range and over 23,000 employees, CACI is recognized as one of the fastest-growing defense prime contractors, having successfully pivoted from pure IT services into high-margin electronic warfare (EW) and signals intelligence hardware.\n\nCACi's core portfolio spans intelligence solutions, SIGINT, electronic warfare systems, C5ISR (Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance), cloud modernization, and enterprise IT. The company's move into EW hardware has differentiated it from peers and driven above-market growth, including wins on DoD programs requiring domestically produced EW systems. CACI has bolstered its hardware and spectrum capabilities through strategic acquisitions including LGS Innovations in 2018.\n\nCACi serves customers across the military branches, intelligence community, and DHS. 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.
