The Thesis
CACI International is a national security technology company that builds high-tech tools and provides expertise for the U.S. military and intelligence agencies. Revenue for the most recently completed fiscal year reached $8.63 billion, representing 13% growth over the prior year. The $2.6 billion acquisition of ARKA Group in 2026 marks the structural shift that pivots CACI toward high-margin space and geospatial intelligence.
If you own CACI, you're betting on four things at once.
In our view, there is meaningful upside still ahead, driven by the massive gap between the current stock price and the value of CACI's record contract backlog. The case breaks if organic growth slows below 5% for two quarters, or if integration costs from ARKA eat the expected margin gains. Both would be visible in the funded backlog and EBITDA margin lines. For long-term investors, CACI is one of the cleaner ways to own the modernization of national security.
Numbers at a Glance
What does it do?
CACI International is a maturing business that earns money by providing technical expertise and specialized technology for U.S. national security missions. The company operates as a prime contractor for the Department of Defense and intelligence agencies, winning long-term contracts that typically last three to ten years. CACI provides everything from signals intelligence and cyber defense tools to the modernization of legacy government IT systems. Customers pay through a mix of fixed-price and cost-plus contracts, which create a highly predictable and recurring revenue stream.
Where does revenue come from?
The vast majority of revenue comes from the U.S. government, with a heavy focus on the Department of Defense and the Intelligence Community. Revenue is split between expertise services, where CACI provides high-end consulting, and technology products like electronic warfare systems. The company also maintains a smaller international segment that supports allied defense missions.
Revenue Breakdown
Revenue by Geography
Who are its customers?
CACI International serves the U.S. Department of Defense and Intelligence Community, with a total contract backlog of $33.4 billion as of March 2026. This massive backlog includes $5.0 billion in funded backlog, which grew 19% year-over-year. The customer base is concentrated within federal agencies, with high-profile wins including a $371 million intelligence community extension and a $287 million U.S. Army modernization project. Management tracks the book-to-bill ratio and the funded backlog as primary indicators of customer demand and future revenue security.
What gives it staying power?
CACI has staying power because its technology is embedded into the most sensitive, multi-year national security programs where switching costs are extremely high. Replacing a primary contractor mid-mission is risky and expensive for the government. This creates a sticky relationship with agencies that have worked with CACI for decades.
Where is it headed?
The company is making a major strategic bet on space and geospatial intelligence through its $2.6 billion acquisition of ARKA Group. Management wants to move CACI away from lower-margin labor services toward high-end sensing and satellite technology. If this works, it will increase the company's pricing power and expand its total addressable market within the rapidly growing space defense sector.
Organic revenue growth of 6.8% in the most recent quarter proves the business is successfully capturing new market share. This growth led to an 8.5% total revenue increase, showing that CACI is expanding through both new contract wins and strategic additions.
Free cash flow of $480 million in the last fiscal year tracks closely with net income, indicating high earnings quality. The company maintains a reliable cash conversion cycle, with days sales outstanding holding steady at 55 days.
The balance sheet now carries significant debt following the $2.6 billion cash acquisition of ARKA Group. While leverage has increased, the company's $33.4 billion backlog provides a massive cushion to service this debt through predictable future cash flows.
CACI is a financially disciplined compounder that is successfully trading service volume for higher-margin technology work.
Funded backlog grew by 19% to $5.0 billion, providing a massive amount of guaranteed revenue for the coming quarters. This growth in the funded portion of the backlog suggests that agencies are moving quickly to deploy capital into CACI's specific technology areas.
Interest expense is rising significantly due to the debt taken on for the ARKA acquisition. We need to watch if higher interest costs eat too much of the operational profit gains before the company can pay down the balance.

[INDUSTRY] The government technology services market is roughly $150 billion today and is growing at a steady 7% clip as agencies modernize legacy systems. The industry is on track to exceed $200 billion by 2029 as national security priorities shift toward cyber defense and space-based intelligence. Pricing power is structural because high-level security clearances and deep mission knowledge create massive barriers to entry. CACI stands as a dominant mid-tier leader that is successfully moving up the value chain to compete with the largest defense primes.
[COMPETITION] The competitive dynamic is rationally structured but requires constant investment in technical talent and security clearances. Barriers to entry are incredibly high because it takes years for new entrants to gain the necessary trust and cleared personnel to bid on prime contracts. This limits the pool of competition to a handful of established players.
Leidos and Booz Allen are the most dangerous threats because they possess the same level of cleared technical expertise and global scale as CACI. Booz Allen in particular is a threat due to its aggressive push into AI and high-end intelligence consulting. SAIC competes more on scale and price in the civilian and enterprise IT segments.
CACI is gaining share in the high-end technology market, evidenced by its 19% growth in funded backlog. The company is successfully outgrowing the broader defense budget by specializing in high-demand niches like electronic warfare.
[MOAT] The primary source of protection is high switching costs coupled with specialized mission knowledge that cannot be easily replicated. CACI's deep integration into the U.S. Navy and intelligence community creates a structural advantage where the cost of failure for a customer is too high to risk a change. The $33.4 billion backlog is the concrete proof of this stickiness.
Net margins of 5.9% are thin, but the 13.1% ROE proves that CACI is capital-efficient in a service-heavy industry. The combination of a 19% funded backlog growth rate and steady margins proves the moat is real rather than just a cyclical tailwind. The business is effectively using its incumbent position to win higher-margin work.
The moat is strengthening as CACI pivots from labor-based services to proprietary technology platforms.
Organic revenue growth of 6.8% beat internal targets in Q3 FY2026.
Spent $2.6 billion to acquire ARKA, pivoting toward higher-margin space technology.

Capital Allocation Track Record
Management has built a reputation for conservative guidance and consistent delivery on organic growth targets. The decision to spend $2.6 billion on ARKA is a bold but necessary move to diversify away from labor services into high-tech space sensing. Their ability to maintain a 1.0x book-to-bill ratio while integrating large acquisitions proves they are capable operators who prioritize long-term contract visibility.
