Arka Group Acquisition
Arka Group was acquired by CACI International for $2.6B on 22 December 2025.
The acquisition price implies a 4.0x revenue and 17.3x EBITDA multiple on $650M of revenue.
CACI International Inc., a leading provider of IT and professional services to U.S. national security customers, completed its $2.6 billion all-cash acquisition of ARKA Group L.P. on March 9, 2026. ARKA specializes in industry-leading electro-optical/infrared (EO/IR) and hyperspectral imaging capabilities via space-based sensors, along with Agentic AI-based software for robust geospatial intelligence supporting critical national security missions. The deal, initially announced December 29, 2025, saw ARKA acquired from funds managed by Blackstone Tactical Opportunities, with over 1,100 ARKA employees joining CACI. The strategic rationale centers on accelerating CACI's space market expansion in a high-barrier domain, complementing its existing signals intelligence and multi-domain sensor portfolio across land, sea, air, and now space. ARKA's technologies enable CACI to deliver software-defined, multi-source intelligence more rapidly to military and intelligence customers, strengthening its position in national security space programs. CACI funded the purchase using an $800 million Incremental Term B-2 Loan maturing March 9, 2033, revolving credit borrowings, cash on hand, and a $500 million bond offering, with Wells Fargo as financial advisor and Gibson Dunn as legal counsel; J.P. Morgan, Evercore, and Simpson Thacher & Bartlett advised ARKA.
