The Acquisition Playbook.

Three patterns run through CACI INTERNATIONAL's acquisitions — what it looks for, how it pays, and how it folds in what it buys.

01
Acquisition criteria
Buy mission technology, not just headcount.
CACI's recent flagship deals — ARKA Group ($2.6B, space-based sensing), Azure Summit ($1.275B, RF/electromagnetic spectrum), LGS Innovations and Mastodon ($975M, SIGINT/EW/cyber products) — all add differentiated, productized technology rather than commodity staffing. Management repeatedly frames these as expanding CACI's offerings across ISR, electronic warfare, and signals intelligence for escalating-threat environments.

02
Capital deployment
A disciplined cadence of cleared, government-facing tuck-ins.
From AlphaInsight and Information Systems Support (2006) through Athena, Dragon Development and IQM (2007) to ID Technologies (2021) and Applied Insight (2024), CACI consistently absorbs small-to-mid federal IT and intelligence firms — many with highly cleared workforces — to deepen its presence with the Intelligence Community, DoD, and federal civilian customers.

03
Integration approach
Debt-financed scale-ups timed to step-change capability.
The largest deals are paired with fresh credit facilities, term loans and senior notes (the L-3 NSS, Six3, Azure Summit and ARKA acquisitions each appear alongside financing 8-Ks), letting CACI move opportunistically into adjacent technology domains — space, electronic warfare, photonics — when assets become available.
