“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.

“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.
