On December 22, CACI International Inc announced that it has entered into a definitive agreement to acquire ARKA Group L.P. from funds managed by Blackstone Tactical Opportunities (Blackstone) in an all-cash transaction for $2.6 billion. Aligned with CACI’s commitment to delivering advanced technology for national security customers, ARKA supports national security missions through its space-based sensor portfolio and ground-based software processing, accelerating the delivery of actionable intelligence to the warfighter.
“The acquisition of ARKA represents a significant step forward in our space strategy,” said John Mengucci, CACI president and chief executive officer. “They bring deep experience and proven performance as a best-in-class provider of national security space and defense capabilities, which has been enhanced by Blackstone’s constructive stewardship of the business during their ownership. With a shared heritage spanning more than sixty years, CACI and ARKA address complex mission requirements and deliver future-ready solutions at the speed and scale required to expand the limits of national security.”
“For our shareholders, the acquisition of ARKA positions CACI to capture significant future opportunities in the space domain across Intelligence Community, U.S. Space Force, and other Department of War customers,” said Mengucci. “The combination enhances our ability to drive long-term growth in free cash flow and generate additional shareholder value.”
“I am confident that CACI will provide outstanding pathways for our employees to thrive,” said Andreas Nonnenmacher, ARKA president and chief executive officer. “Our aligned mission-focused cultures and deep engineering roots create a strong foundation for future innovation and growth, and our customers will benefit right away from the expanded capabilities of the combined company.”
As a result of the $2.6 billion all-cash transaction, CACI expects to realize a tax benefit with a present value of $225 million. CACI expects the transaction to close in the third quarter of fiscal year 2026, subject to regulatory approvals and customary closing conditions.
