Business Overview: Science Applications International Corporation (NASDAQ: SAIC)

---

Executive Summary

Science Applications International Corporation (SAIC) is a technical, engineering, and enterprise IT services provider whose business is built almost entirely on the U.S. federal government. Roughly 98% of revenue in recent fiscal years has come from U.S. government prime contracts or subcontracts, with the Department of Defense and the Intelligence Community together accounting for the large majority of that total.

SAIC generated approximately $7.5 billion in revenue in fiscal 2025 and reorganized in February 2024 into five business groups aggregated under two reportable segments — Defense and Intelligence and Civilian — reflecting a push to align delivery teams more tightly with mission areas like undersea dominance, border security, and next-generation space, rather than organizing purely around contract type.

1. Core Business Model & How They Work

SAIC's revenue is earned by staffing and delivering technical work under government contracts, with the economics varying significantly by contract type.

[ Government Agency Need ] ➡️ [ Contract Award (prime or sub) ] ➡️ [ Staffing & Delivery ] ➡️ [ Billing by Contract Type ] ➡️ [ Recompete / Extension ]

Contract Type Mix (Fiscal 2025)

1. Cost-reimbursable (62% of revenue) — SAIC is paid for allowable costs plus a fee; lower risk, but also a capped upside.
2. Time-and-materials (22% of revenue) — SAIC bills negotiated hourly rates plus direct costs; margin depends on utilization and rate realization.
3. Firm-fixed-price (16% of revenue) — SAIC is paid a set price regardless of actual cost, so it captures the upside of efficient delivery but bears the risk of cost overruns.

Customer Concentration

• Department of Defense: ~52% of revenue (FY2025 and FY2024)
• Intelligence and other federal agencies: ~46%
• Commercial, state/local, and international: the remainder
• Virtually all revenue is U.S.-based, and the company manages roughly 1,700 active contracts and task orders across every branch of the U.S. military plus DoD, NASA, State, Justice, DHS, and the Intelligence Community.

Both segments draw on five underlying business groups, and an internal "Innovation Factory" develops enterprise-class solutions that get deployed across both segments rather than siloed by customer type.

                   (pure-play government IT/technical
                    services peers)

• Large defense primes with IT divisions (General Dynamics, Northrop Grumman, RTX) compete on scale and platform ownership but are less purely IT/services-focused than SAIC.
• Pure-play government technical/IT services firms (Booz Allen Hamilton, CACI, Leidos, ManTech, Serco) are SAIC's closest peer set, competing on cleared personnel, past performance, and pricing — and are frequently also teaming partners on joint bids.
• Diversified commercial IT providers (Accenture, IBM) bring broader technology capability but typically less depth in cleared, mission-specific government work.

SAIC competes on technical expertise, the size of its cleared workforce, cost-effective and timely innovation, past performance and reputation, pricing, and overall scale and geographic presence.

5. Strategic Strengths & Risks

Strengths

• Security-cleared workforce: A large base of cleared personnel (SAIC employs roughly 24,000 people, including more than 6,000 active military or veterans) is a genuine, slow-to-replicate asset in a labor market where clearances are scarce and valuable.
• Entrenchment in long-lifecycle programs: Weapon systems, ground vehicle, and sustainment work tends to run for years or decades, creating high switching costs once SAIC is the incumbent.
• Certifications and compliance infrastructure: ISO 9001, ISO/IEC 27001, AS9100D, and CMMI-DEV Maturity Level 3 certifications are table stakes for competing on many government bids and represent a real, if modest, barrier to new entrants.
• Diversified contract base: ~1,700 active contracts and task orders reduce single-contract concentration risk relative to smaller competitors.

Risks

• Near-total dependence on U.S. government spending: ~98% of revenue is tied to government budgets and political priorities; a sustained defense or civilian-agency budget slowdown, continuing resolutions, or shutdowns can directly disrupt bookings and billing.
• Guidance and delivery delays: SAIC has trimmed its sales outlook in recent periods and cited delivery delays even as it reiterated longer-term revenue guidance (roughly $7.6–$7.75 billion for fiscal 2026), signaling execution and contract-timing risk even with a healthy backlog.
• Firm-fixed-price exposure: The 16% of revenue under firm-fixed-price contracts carries real downside if SAIC underestimates delivery costs.
• Recompete risk: Government contracts are periodically re-bid; losing a recompete on a major program can create a sudden, material revenue gap.
• Talent competition: Cleared technical talent is in high demand across the sector, and wage inflation or attrition can pressure margins on cost-reimbursable and T&M work.

7. Summary Conclusion

SAIC's moat rests on a deep, cleared technical workforce and long-duration incumbency across defense and civilian government programs — assets that are genuinely difficult and slow for a new entrant to assemble, but that also tie the company's fortunes almost entirely to U.S. government budget cycles and political priorities. The February 2024 reorganization into Defense and Intelligence and Civilian segments, built around five underlying business groups and an internal Innovation Factory, is a bet that aligning delivery around mission areas (rather than contract type) will sharpen SAIC's competitive position against both pure-play peers like Leidos and CACI and larger defense primes. The bigger near-term question is execution: management has both reiterated multibillion-dollar revenue guidance and acknowledged delivery delays in the same breath, making the pace of contract conversion the key variable to watch.
