CACI International announced it has entered into a definitive agreement to acquire ARKA Group L.P. from funds managed by Blackstone Tactical Opportunities in an all-cash transaction valued at $2.6 billion, a deal the company says advances its strategy in space-based sensing and intelligence for national security customers.
CACI said ARKA’s portfolio spans space-based sensors and ground-based software processing that accelerates the delivery of actionable intelligence to military and defense stakeholders. CACI expects the acquisition to expand its addressable opportunities across the Intelligence Community, the U.S. Space Force, and other Department of Defense customers.
The transaction is expected to close in CACI’s third quarter of fiscal year 2026, subject to regulatory approvals and customary closing conditions. CACI also said it expects to realize a tax benefit with a present value of $225 million due to the all-cash structure.
Wells Fargo served as CACI’s exclusive financial advisor and provided committed financing, while Gibson Dunn acted as legal advisor to CACI. J.P. Morgan Securities and Evercore served as financial advisors to ARKA, with Simpson Thacher & Bartlett acting as ARKA’s legal advisor.
ARKA, headquartered in Danbury, Connecticut, describes itself as a fully integrated mission partner with capabilities spanning optical technologies, information processing and analytics, and trusted communications supporting U.S. and international mission partners.
