CACI International is a defense and intelligence technology company that provides software, sensors, and specialized expertise to the U.S. military and national security agencies. In its most recently completed fiscal year, the business generated $8.63 billion in revenue, growing more than 12% compared to the prior year. It currently maintains a massive $33.4 billion backlog of signed contracts, which is roughly three and a half times its annual sales.
The investment thesis on CACI is that its multi-year shift from low-margin services to high-end mission technology is finally showing up in faster revenue growth and higher profit margins. Management is aggressively using its cash to buy companies with specialized intellectual property in electronic warfare, space sensors, and artificial intelligence. If it continues to win these high-tech contracts while converting its record backlog into cash, the business should grow significantly faster than the overall defense budget.
We think CACI is a high-quality business that the market is valuing like a slow-moving government contractor, despite its accelerating growth and strong competitive position. The combination of record funding for national security and CACI's shift into high-demand areas like space and electronic warfare makes for a very strong outlook.
CACI stock climbed steadily for years before dropping recently as the market cooled down. The company has been growing by winning huge defense contracts and building high-tech gear for the military. Even though it is making more money than ever, the stock price has fallen back lately from its earlier highs.
What does it do?
CACI International is a growth-stage business that earns money by providing specialized technology and expertise to U.S. government agencies through long-term contracts. The company operates as a primary partner for the Department of Defense and the intelligence community, helping them modernize their digital systems and deploy advanced hardware like signal-intelligence sensors. Money flows through three main contract types: cost-plus, which covers expenses plus a fee; time-and-materials, where CACI is paid for hours worked; and fixed-price, where CACI earns more profit by being efficient. Customers keep paying because CACI embeds itself in mission-critical tasks, such as managing the U.S. Army’s personnel and pay systems, which are difficult and risky to transition to a competitor.
Where does revenue come from?
The vast majority of CACI's revenue comes from providing high-end expertise and technology to defense and intelligence agencies. Expertise revenue includes professional services like intelligence analysis and engineering support, while technology revenue comes from developing and maintaining software platforms and advanced hardware. Roughly 95% of its sales come from the U.S. federal government, making its revenue stream highly dependable and tied to national security spending.
Revenue Breakdown
Revenue by Geography
Who are its customers?
CACI International serves the U.S. Department of Defense, the intelligence community, and federal civilian agencies. The Department of Defense is its largest customer, accounting for 73% of total revenue in the most recent quarter. The company also supports intelligence agencies, which make up about 22% of sales, and various federal civilian departments that account for the remaining 5%. In its most recent reported quarter, CACI secured $2.2 billion in new contract awards, which included a $371 million intelligence contract and a $287 million modernization deal for the U.S. Army. Total backlog has grown to $33.4 billion, with $5.0 billion of that already funded and ready for immediate work.
What gives it staying power?
CACI has staying power because it manages massive, complex government systems with extremely high switching costs. Once a company has spent years migrating a military branch's pay system or mission-critical workloads to a new cloud platform, the risk and cost of replacing them are prohibitive.
Where is it headed?
CACI is aggressively moving into high-end mission technology through major acquisitions in space sensors and electronic warfare. By spending $2.6 billion to buy ARKA Group and another $1.275 billion for Azure Summit, management is pivoting the business toward high-margin hardware and AI software. This strategy aims to capture the growing demand for geospatial intelligence and space-based defense.
Verdict: Revenue is growing at its fastest pace in years as CACI wins larger, more complex technology contracts. Revenue grew 8.5% in the most recent quarter, reaching $2.35 billion, while organic growth stayed healthy at 6.8%. This acceleration shows CACI is successfully taking market share in high-priority defense areas.
Verdict: Free cash flow is robust and tracks closely with net income, though recent acquisitions have temporarily increased debt. The company generated $221 million in free cash flow in the latest quarter, up 18% year-over-year. Management is consistently converting over 100% of its adjusted net income into cash, providing the fuel for its aggressive M&A strategy.
Verdict: The balance sheet is heavily leveraged following two multibillion-dollar acquisitions, but the cash flow profile remains supportive. CACI’s debt-to-equity ratio sits at 1.31x after funding the $2.6 billion ARKA deal. While debt is higher than its historical average, the company’s $33.4 billion backlog provides the revenue visibility needed to comfortably pay down these obligations.
CACI is a financially disciplined business that is successfully using its strong cash flow to buy its way into higher-margin technology markets.
The $33.4 billion total backlog is at a record high and provides incredible visibility into future revenue. This growing mountain of contracted work, which rose 6% this year, ensures that CACI can sustain its growth even if new contract awards slow down temporarily.
Interest expense is rising sharply as the company takes on debt to fund its $2.6 billion ARKA acquisition. Higher rates could eat into the earnings gains from these new businesses if CACI does not pay down its debt as quickly as management expects.
The U.S. government technology services market is roughly $100 billion today and grows at about 5% annually, largely tracking the Department of Defense budget. This market is on track to exceed $125 billion by 2029 as the military prioritizes digital modernization over traditional hardware. It is a structurally stable industry with high barriers to entry due to security clearances and complex regulatory requirements. CACI stands as a top-tier leader, successfully shifting from a niche services provider to a broad technology prime contractor with a massive multi-year runway.
Competition in the federal space is intense but largely rational, focused on long-term contract bids rather than daily price wars. Barriers to entry are high because winning work requires deep institutional knowledge and thousands of employees with top-secret clearances. Pricing power is protected by the complexity of the work, which prevents customers from easily switching providers.
Leidos and Booz Allen Hamilton are the most formidable rivals, often bidding for the same $500 million-plus technology programs. Leidos uses its massive scale to bid on the largest enterprise contracts, while Booz Allen focuses on high-end consulting. CACI’s strategic threat comes from these larger peers using their scale to underbid on major system integrations.
CACI is currently gaining share in technology-heavy segments like electronic warfare and space. Its 6.8% organic growth outpaces many peers, proving its specialized offerings are winning in the market. CACI is a dominant player in its chosen niches.
CACI's primary protection comes from extremely high switching costs embedded in its long-term technology contracts. When CACI manages a mission-critical platform like the U.S. Army's integrated personnel system, the "rip and replace" risk is so high that the government rarely switches providers once a system is operational. Its $33.4 billion backlog is the best evidence of this lock-in, representing more than three years of guaranteed work.
The company's financials support this narrow moat, with a healthy 12.3% EBITDA margin that has remained resilient even as the company scales. While its ROIC of 6.6% is modest, it reflects the heavy capital used for recent acquisitions rather than a lack of pricing power. The numbers prove CACI is a durable business that can defend its margins through cycles.
CACI’s moat is strengthening as it moves from labor-based services to proprietary technology and hardware. The shift toward specialized IP in space and AI makes its services even harder to replicate or replace.
Beaten and raised revenue guidance for three consecutive quarters in FY2026.
Deployed over $4B for high-margin tech acquisitions like ARKA and Azure Summit.
CEO John Mengucci holds substantial equity and pay is tied to EBITDA targets.
Capital Allocation Track Record
John Mengucci has proven to be a decisive leader who is successfully transforming CACI from a steady services firm into a high-growth technology power. Since taking over as CEO, he has hit or exceeded guidance consistently and orchestrated a series of smart, high-tech acquisitions that have expanded the company’s margins. His decision to focus the company on electronic warfare and space-based intelligence has aligned perfectly with the U.S. government's recent spending priorities.
The primary governance risk is the high level of execution required to integrate nearly $4 billion in recent acquisitions, making the strategy highly dependent on Mengucci’s leadership. While CACI has a deep bench of experienced executives, like CFO Jeff MacLauchlan, the rapid pivot to a technology-first model is a complex transition. However, the board is independent and incentives are well-aligned with long-term EBITDA and cash flow targets rather than short-term stock moves.
We expect revenue to grow from $9.6B in FY2026 to $14.8B in FY2031 (~9% CAGR), with EPS growing from $28.23 to $44.92 (~10% CAGR). Growth is driven by a steady increase in long-term national security contracts and government modernization projects. Profit margins improve as the company shifts toward higher-value technology services and spreads administrative costs over a larger business. EPS grows faster than revenue because profit margins are expanding and the company is buying back its own shares. Operating margin expected to reach ~11% by FY2031.
Space-based intelligence becomes a massive new revenue pillar. The $2.6 billion ARKA acquisition gives CACI dominant sensors for the next generation of satellite-based surveillance.
Electronic warfare systems reach full-rate production. CACI's Spectral program moving into full production would drive significantly higher hardware margins than traditional services.
Modernization of legacy federal systems accelerates. As more government agencies move to the cloud, CACI's record in large-scale ERP migrations positions it to win massive new contracts.
High debt levels limit flexibility for future deals. Carrying over $3 billion in debt following recent acquisitions leaves CACI vulnerable if interest rates stay high for years.
A major shift in defense spending priorities. If the U.S. pivots away from the specific tech niches CACI has bought into, its expensive acquisitions could face impairments.
Integration failure of the ARKA and Azure Summit deals. Failing to meld these large, high-tech cultures could lead to talent flight and missed growth targets.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach (price-to-earnings applied to next year's earnings) as our primary framework. It fits CACI because the company has predictable, GAAP-profitable earnings backed by multi-year government contracts, and the shift toward higher-margin "Technology" revenue is most cleanly captured by the expansion of its earnings multiple.
Multiplying the FY2027 EPS estimate of $31.25 by a 20x multiple results in a fair value of $625 per share. Our 20x multiple sits at the higher end of the peer range (Booz Allen 22x, Leidos 19x, SAIC 15x), which we believe is justified by CACI's superior backlog-to-revenue ratio and its faster transition toward proprietary defense technology. We used the FY2027 EPS of $31.25 directly from the deterministic projection to ensure consistency across the report.
A cross-check using EV/EBITDA (FY2027 EBITDA $1.2B × 14x peer multiple) yields a fair value of $511, which is within 18% of our primary $625 target. While the EV/EBITDA method is more sensitive to CACI's $5.4 billion net debt, the 18% difference is well within our 25% tolerance for agreement. We trust the Forward P/E framework more in this instance because CACI’s ongoing debt paydown and transition to software-driven contracts will likely cause net income to grow faster than EBITDA, making P/E the more forward-looking signal for equity holders.
We are assuming CACI successfully transitions its revenue mix toward "Technology" contracts, reaching 60% of total sales by FY2028. The company is pivoting from labor-intensive services to proprietary software, space sensors, and AI-driven platforms, which carry significantly higher margins and higher barriers to entry. Current trends show Technology Service already at 55.4% of revenue, making this shift highly probable.
We're assuming the ARKA acquisition and new AI-focused products expand the adjusted net margin toward 7% over the next three years. Management has guided toward margin expansion, and recent results show a 16.6% year-over-year jump in net income, which supports the thesis that CACI is finding operational leverage as it scales its technology portfolio.
We are assuming the massive $34 billion total backlog converts to revenue at a steady 20% annual rate. This conversion is consistent with historical patterns and is supported by the 2.2x book-to-bill ratio seen in recent quarters, providing high visibility into cash flows that insulate the stock from broader economic volatility.
The single biggest risk is a prolonged U.S. government budget stalemate or debt ceiling fight that halts funding for "new start" programs. This would freeze the conversion of CACI's $34 billion backlog into recognized revenue, potentially knocking $20 to $30 off the fair value as the forward multiple compresses. Watch the "Days Sales Outstanding" (DSO) and funded backlog levels for early signs of government payment or award delays.
Bear case ($480): Funding delays from a "Continuing Resolution" last more than six months, stalling the $22 billion bid pipeline; or Integration issues with the ARKA acquisition lead to a 150-basis-point drop in projected operating margins.
Bull case ($750): Book-to-bill ratio exceeds 1.5x for three consecutive quarters, signaling a structural acceleration in contract awards; or Agentic AI and space sensor software grow to represent over 15% of total revenue, driving a multiple re-rating.

The market is leaning bullish because CACI is successfully swapping low-margin labor work for high-profit mission technology contracts. The company is hitting double-digit revenue growth while securing a massive 33 billion dollar backlog. This shift toward advanced software and space sensors creates a predictable pipeline that protects earnings from routine competition.
Skeptics think that CACI's heavy reliance on government budgets makes its long-term growth ceiling far lower than the current stock price implies. Because nearly all income depends on federal military contracts, the company has no way to sell to private businesses if security spending stagnates or specific government priorities shift away from their current capabilities.
