Business Overview: Leonardo DRS, Inc. (NASDAQ: DRS)

---

Executive Summary

Leonardo DRS, Inc. is a mid-sized U.S. defense technology company headquartered in Arlington, Virginia, with more than 55 years of history supplying advanced sensing, network computing, force protection, and electric power and propulsion technologies to the U.S. military and allied defense forces. The company took its current public form in 2022 through the de-SPAC-style merger of RADA Electronic Industries (an Israeli-American defense electronics firm) with the U.S. defense business Leonardo DRS, creating a NASDAQ-listed entity that remains majority-owned by Leonardo S.p.A. of Italy, one of the world's largest aerospace, defense, and security groups.

The company organizes its work into two reportable segments — Advanced Sensing and Computing (ASC) and Integrated Mission Systems (IMS) — and serves customers across land, air, sea, space, and cyber domains. Roughly 80% of revenue flows from the U.S. government, with the remainder from foreign militaries and commercial buyers, and the company most often acts as a subcontractor or system provider to larger prime contractors rather than as the lead prime on major platforms.

Why it matters: Leonardo DRS sits inside many of the U.S. Department of War's highest-priority modernization programs — submarine electric propulsion, counter-drone (C-UAS) defense, infrared sensing, and tactical network computing — giving it durable, incumbent positions in programs that are difficult for competitors to displace and that benefit from rising U.S. and allied defense budgets.

1. Core Business Model & How They Work

Leonardo DRS operates the classic defense-electronics subcontractor/prime model: it wins competitively bid or sole-source government and prime-contractor awards, then designs, engineers, and manufactures specialized sensing, computing, power, and protection systems that are integrated onto military platforms (ships, vehicles, aircraft, satellites, and soldier systems). In 2025, 39% of revenue came from prime contracts directly with the U.S. government and 61% from subcontracts where DRS supplies a system or subsystem to another platform integrator. Contracts are a mix of firm-fixed-price (the majority, $3.2B in 2025) and flexibly priced cost-type/time-and-materials work ($443M in 2025), and the company's long production-phase and incumbent positions mean no single contract exceeded 10% of revenue in any of the last three years.

2. Business Segments

Leonardo DRS FY2025 Revenue: $3.648B
├── Advanced Sensing and Computing (ASC) ........ ~65% ($2,355M, +11% YoY)
└── Integrated Mission Systems (IMS) ............ ~35% ($1,307M, +15% YoY)

Advanced Sensing and Computing (ASC) designs, develops, and manufactures sensing and network computing technology for real-time situational awareness. Its sensing portfolio spans electro-optical/infrared (EO/IR), signals intelligence (SIGINT), electronic warfare (EW), ground-vehicle sensing, active electronically scanned array (AESA) tactical radars, dismounted-soldier sensing, and space sensing. Its network computing products provide rugged edge computing for shipboard and ground platforms, built on the company's proprietary SAGEcore™ open-architecture software. ASC generated $316M of segment Adjusted EBITDA in 2025 (13.4% margin).

Integrated Mission Systems (IMS) designs, develops, manufactures, and integrates power conversion and distribution systems, ship propulsion, motors, and variable frequency drives, force protection systems, and transportation/logistics systems. Flagship programs include electric propulsion for the Columbia Class ballistic missile submarine, other Navy electrical and thermal systems, and short-range air defense and counter-unmanned aircraft systems (C-UAS) mounted on ground vehicles. IMS generated $137M of segment Adjusted EBITDA in 2025 (10.5% margin).

4. Competitive Landscape

Leonardo DRS competes against divisions of much larger defense primes as well as mid-tier and smaller specialized firms, and it frequently teams with the same companies it competes against:

• L3Harris Technologies — broad overlap in EO/IR sensors, network computing, and electronic warfare; larger scale and R&D budget.
• BAE Systems — competes in ground-vehicle sensing, force protection, and combat systems; a much larger, diversified prime.
• Elbit Systems of America — close competitor in EO/IR, soldier systems, and night-vision/targeting technology.
• Teledyne FLIR — direct competitor in thermal/infrared imaging sensors.
• RTX (Raytheon) and Lockheed Martin — compete in select radar, missile-defense, and sensing niches, and are also major customers/partners on integrated platforms.
• General Dynamics — overlaps in ground-vehicle electronics and naval systems.

DRS's 10-K notes that the U.S. government's growing use of multi-award contract vehicles increases pricing pressure, and that larger competitors can sometimes price aggressively given their greater resources, while smaller/non-traditional entrants can undercut on cost or speed. DRS differentiates on product performance, embedded/incumbent positions, past performance, delivery schedule, and innovation rather than competing purely on price.

5. Strategic Strengths & Risks

Moat Sources

• Program incumbency: Decades-long embedded positions (e.g., Columbia Class propulsion, legacy EO/IR programs) are difficult and costly for the government to re-compete or re-qualify elsewhere.
• Security clearances & ITAR barriers: Defense electronics work requires facility and personnel security clearances and compliance with U.S. export-control regimes (ITAR/EAR), which raise the bar for new entrants, especially foreign ones.
• Specialized IP: Proprietary technology such as SAGEcore™ open-architecture computing and advanced IR-sensor know-how create switching costs once designed into a platform.
• Majority ownership by Leonardo S.p.A. provides access to European defense relationships, co-development opportunities, and balance-sheet support.

Key Risks

• U.S. defense budget and appropriations cyclicality, including continuing-resolution/shutdown risk and shifting DoW priorities, can delay funding and bookings.
• Program/customer concentration, with roughly 80% of revenue tied to the U.S. government and Navy/Army together making up 72% of U.S. government revenue in 2025.
• Geopolitical and export-control exposure, given foreign military sales and the company's structural ties to an Italian parent, which is itself subject to a government proxy/voting agreement governing DRS's U.S. operations.
• Supply chain pressure, with the 10-K specifically citing shortages of germanium and other raw materials, castings, and electronic components.
• Pricing pressure from multi-award contract vehicles and larger competitors with greater resources.

7. Summary Conclusion

Leonardo DRS occupies a durable, specialized niche within the U.S. and allied defense-industrial base: it is not the lead prime on the largest weapons platforms, but it supplies the sensing, computing, power, and force-protection "nervous system" that those platforms depend on. That embedded, subcontractor-heavy model — combined with multi-decade program incumbency, security-clearance barriers, and majority ownership by Leonardo S.p.A. — gives the company meaningfully better earnings visibility (an $8.7B backlog against ~$3.6B of annual revenue) than a typical industrial company.

The near-term growth story is reinforced by urgent, well-funded priorities — counter-drone defense, submarine modernization, and tactical network computing — that played directly into 13% revenue growth and 31% net-earnings growth in 2025. The principal risks remain structurally tied to U.S. defense appropriations cycles, customer concentration in the Navy and Army, and supply-chain/export-control exposure, but the company's FY2026 guidance points to continued growth as these defense priorities remain funded.
