(LDOS) Leidos Holdings, Inc. Company Overview

What does Leidos Holdings do?

Leidos Holdings, Inc. is a Reston, Virginia-based technology, engineering, and mission-support contractor listed on the NYSE under ticker LDOS. Its practical role is to turn complex government and regulated commercial missions into operating systems, software, cyber programs, health services, energy engineering, aviation systems, and defense products. The company describes itself as serving government and commercial customers with digital and mission innovations, and its investor materials frame the current strategy around national security, health, and critical infrastructure. The business is not a pure weapons prime, not a pure IT outsourcer, and not a traditional consulting firm; it sits between those categories, integrating technical talent, cleared labor, program management, and mission-specific platforms.

What customers define the business?

Leidos’ customer map is highly concentrated in the public sector. In the 2025 annual report, the company said U.S. government contracts generated 87% of FY2025 revenue, while contracts with the Department of War and the U.S. Intelligence Community represented about 49% of total revenue. Key customers include defense, intelligence, homeland security, the FAA, the Department of Veterans Affairs, other U.S. civilian agencies, state and local agencies, foreign governments, and selected commercial businesses. Only about 8% of FY2025 revenue came from entities outside the United States, so the primary analytical lens is U.S. mission spending and contract execution rather than global consumer demand.

How does the mission mix shape risk?

The same public-sector exposure that creates durable demand also makes Leidos sensitive to federal budgets, continuing resolutions, procurement delays, bid protests, and stop-work orders. That is the central trade-off in the Leidos model: demand is often mission-critical and long duration, but revenue conversion depends on appropriated funding, customer priorities, and contract performance. The company’s official company overview emphasizes five growth engines, but the financial model still starts with government contract economics and backlog conversion.

How does Leidos make money?

Leidos makes money by winning and performing contracts for technology-enabled services, systems integration, engineering, analytics, cyber, managed health, logistics, mission software, aviation, energy, and defense programs. Revenue usually arrives through negotiated contracts rather than through retail transactions. In FY2025, Leidos’ disclosed contract mix was 44% cost-reimbursement and fixed-price-incentive-fee, 43% firm-fixed-price, and 13% time-and-materials or fixed-price-level-of-effort. That mix is important because a services contractor can grow revenue but still miss margin expectations if fixed-price work is poorly estimated or if customer requirements change.

What are the main revenue mechanics?

The revenue engine begins with contract vehicles, proposals, task orders, renewals, and modifications. Leidos competes for definitive awards, IDIQ contracts, GSA schedule work, other transaction authority agreements, and subcontract roles. In a DCF model, this means revenue is less about one product price and more about win rate, funding conversion, labor availability, contract duration, backlog, and recompete performance. High funded backlog can support near-term visibility, while unfunded backlog can create longer-term visibility that still depends on appropriations, options, task orders, and customer execution.

How does contract type affect margin?

Cost-reimbursement work typically reduces cost-overrun risk but can also limit upside. Firm-fixed-price contracts can reward tight execution but punish schedule delays, technical surprises, or changing customer requirements. The Q1 FY2026 release showed this clearly: Homeland non-GAAP margin fell partly because of changing requirements on a fixed-price program, and Defense margin was pressured by schedule delays on a fixed-price development program. For analysts, contract mix is not a footnote; it is a direct driver of operating margin volatility.

Which Leidos segments matter most after the 2026 reporting realignment?

Beginning in fiscal 2026, Leidos began reporting four segments: Intelligence & Digital, Health, Homeland, and Defense. This changed the segment lens from the FY2025 annual report structure of National Security & Digital, Health & Civil, Commercial & International, and Defense Systems. The realignment matters because it makes the current investment debate easier to see: Intelligence & Digital is the largest Q1 FY2026 revenue contributor, Health is the strongest margin engine, Homeland now houses energy infrastructure momentum and Entrust-related costs, and Defense carries product and development-program execution risk.

Which segment generated the most Q1 FY2026 revenue?

What does backlog say about segment durability?

Backlog shows the revenue that Leidos expects to recognize from negotiated contracts and certain sole-source IDIQ task orders when execution and funding are considered probable. At Apr. 3, 2026, total backlog was $48.4B, including $9.6B funded and $38.8B unfunded. Intelligence & Digital had the largest total backlog at $19.3B, followed by Defense at $12.6B, Homeland at $9.9B, and Health at $6.6B. This mix tells researchers that the largest revenue segment also has the largest future work pool, while Health’s margin strength is not the same thing as backlog dominance.

What does Leidos' latest reported period show?

The latest full reporting package before this article was Leidos’ Q1 FY2026 release and Form 10-Q for the three months ended Apr. 3, 2026. The quarter showed revenue growth, strong adjusted profitability, higher operating cash flow, and a more leveraged balance sheet after the Entrust acquisition. In the Q1 FY2026 results release, revenue increased 4% year over year to $4.4B, including 3% organic growth, while net income fell to $335M because acquisition and pending joint venture costs affected GAAP results. Non-GAAP diluted EPS rose 5% to $3.13, which is why the quarter looked stronger on an adjusted basis than on reported net income alone.

What changed in Q1 FY2026?

The most important change was not merely the 4% revenue growth. It was the combination of organic growth, Entrust closing, the security products joint venture signing, and raised full-year guidance. Leidos raised FY2026 revenue guidance to $18.00B-$18.40B, kept adjusted EBITDA margin guidance around the mid-13% range, raised non-GAAP diluted EPS guidance to $12.10-$12.50, and increased expected operating cash flow to about $1.80B. In valuation terms, the quarter supports a thesis of modest revenue acceleration with strong adjusted profitability, but it also adds integration and leverage questions.

What does the balance sheet show after Entrust?

The Q1 FY2026 Form 10-Q reflected a balance sheet that had absorbed a major acquisition. Cash and cash equivalents declined to $457M at Apr. 3, 2026 from $1.108B at Jan. 2, 2026, while total debt increased to about $6.3B from $4.6B. Goodwill rose to $8.094B from $6.342B, and intangible assets increased to $993M from $458M. That is a clear signal that Entrust is not just a small add-on; it changes leverage, goodwill exposure, and the importance of energy-infrastructure execution in the DCF narrative.

What turning points still shape Leidos today?

Leidos’ history matters because the company’s current model was built through separation, merger, capability acquisitions, and portfolio reshaping. The useful history is not a list of trivia; it is the sequence of moves that explains why Leidos now combines cleared federal IT, health services, defense systems, cyber, maritime engineering, security detection, and energy infrastructure. The company’s annual report traces its origin to 1969, when physicist Dr. Robert Beyster founded the predecessor business, while later transaction materials and company releases explain the 2013 separation, the 2016 Lockheed Martin IS&GS combination, and the acquisitions that expanded technical scope.

1. 1969
   The predecessor business was founded by Dr. Robert Beyster, creating the scientific and engineering culture that still frames Leidos as a mission-technology contractor.
2. 2013
   SAIC separated into two public companies; the larger solutions business adopted the Leidos name, clarifying its focus on national security, health, and engineering markets.
3. 2016
   Leidos combined with Lockheed Martin’s IS&GS business in a major Reverse Morris Trust transaction, increasing scale in federal technology and mission services.
4. 2020
   The $1.65B Dynetics acquisition added applied research, defense systems, and advanced technology capabilities.
5. 2021
   Gibbs & Cox expanded naval architecture and maritime engineering capabilities, deepening the space and maritime strategy pillar.
6. 2025
   Kudu Dynamics added AI-enabled cyber capabilities for defense, intelligence, and homeland security customers; FY2025 acquisition consideration was $293M net of cash acquired.
7. 2026
   Leidos completed the roughly $2.4B Entrust acquisition and signed a security products joint venture, shifting the portfolio toward energy resilience and focused security-detection economics.

Which historical moves matter today?

The 2016 IS&GS combination matters because scale and customer intimacy are central in federal technology contracting. Dynetics matters because it helped Leidos move beyond labor-heavy services into more product and development exposure. Kudu Dynamics matters because AI-enabled cyber and mission software are now part of Leidos’ stated NorthStar 2030 strategy. The Entrust acquisition matters because it expands utility engineering and grid modernization at a time when energy resilience, data-center power demand, and electric infrastructure investment are becoming strategic themes.

What gives Leidos a competitive advantage in government technology?

Leidos’ moat is not a consumer brand or patent wall. It is a combination of scale, past performance, cleared talent, mission relationships, proposal infrastructure, compliance systems, cyber credibility, data-management capability, and the ability to integrate commercial technologies into government missions. The annual report says Leidos competes with large defense contractors, federal IT specialists, commercial technology providers, smaller specialists, government in-house capabilities, and federal nonprofit research centers. It also says the company competes through technical expertise, mission understanding, qualified staff with security clearances, fair pricing, program execution, cybersecurity and compliance, reliable supply chain, data management, and AI integration at scale.

Where is the moat strongest?

Who competes with Leidos?

Leidos names competitors including Accenture Federal Services, Amentum, BAE Systems, Booz Allen Hamilton, CACI, Deloitte, General Dynamics, GovCIO, IBM, L3Harris, Lockheed Martin, ManTech, Northrop Grumman, Optum, Parsons, Peraton, RTX, and SAIC. That list shows why the market is both attractive and difficult: Leidos competes against defense primes, IT integrators, consulting firms, health specialists, and focused government contractors. The competitive battle is often less about the lowest nominal price and more about past performance, technical labor, contract vehicle access, cost realism, security clearance coverage, and the ability to absorb program complexity.

How financially strong is Leidos through the contract cycle?

Leidos is financially strong in operating terms, but its balance sheet became more leveraged after the Entrust acquisition. FY2025 revenue was $17.174B, operating income was $2.109B, operating margin was 12.3%, and net income was $1.462B. Operating cash flow was $1.750B in FY2025, compared with $1.435B in FY2024 and $1.187B in FY2023. That three-year cash-flow pattern is a positive signal for a government services company because working capital, collections, tax timing, and contract mix can create quarterly lumpiness. The key question is whether the higher leverage following Entrust is matched by durable cash flow and synergy realization.

What cash-flow ratios matter?

For DCF work, operating cash flow matters more than headline backlog alone. Leidos generated $1.750B of operating cash flow in FY2025. In Q1 FY2026, operating cash flow was $301M and free cash flow was $270M after $31M of property, equipment, and software payments. The Q1 free-cash-flow conversion looks strong, but it is a short period and includes normal timing effects. Analysts should model full-year cash generation against management’s FY2026 operating cash flow guidance of approximately $1.80B, then test the pace of debt reduction, buybacks, dividends, and acquisition integration.

Who owns Leidos stock and why does governance matter?

Leidos is not a founder-controlled dual-class company. The ownership profile is more typical of a large U.S. public contractor: broad institutional ownership, one class of common stock, and relatively low insider economic ownership. The 2026 proxy statement reported 126,118,109 shares outstanding for beneficial ownership calculations as of Feb. 27, 2026. Vanguard was listed at 15,405,579 shares, or 12.2% of the class, while BlackRock was listed at 8,587,375 shares, or 6.8%. Directors and executive officers as a group beneficially owned 969,081 shares, or approximately 0.77% of the class.

How concentrated is voting influence?

The proxy data suggests dispersed institutional governance rather than controlling-shareholder governance. That matters because capital allocation decisions, acquisition discipline, executive compensation, board composition, and shareholder-return policy are more likely to be evaluated through institutional voting standards. For a contractor with long-term government programs, governance risk is less about a founder overriding minority holders and more about whether the board and management maintain discipline on fixed-price programs, leverage, cybersecurity, acquisition integration, and compliance.

What opportunities and risks could change the Leidos story?

The opportunity side of Leidos is strongest where mission demand is expanding faster than traditional federal IT budgets: AI-enabled cyber, mission software, integrated air defense, intelligence modernization, energy infrastructure, grid reliability, and health services. The Q1 FY2026 release highlighted awards such as a five-year, $869M MACRO II task order for AI-enabled U.S. Army decision systems, more than $461M of DISA GSM-O II cyber task orders, a two-year $335M NSA TechSIGINT modernization contract, and a roughly $284M SEC infrastructure-support contract. The company also signed a security screening joint venture with Analogic, which could sharpen focus around advanced detection systems while leaving Leidos with a minority economics stake.

Which risks are most company-specific?

Leidos’ official risk language is unusually relevant to the financial statements. Government funding delays can directly slow program starts and payments. Bid protests can delay work after an award. Fixed-price program problems can pressure margins. Cybersecurity is both a market opportunity and an operational risk because Leidos handles sensitive systems and data. Acquisitions can create growth but also integration risk, goodwill exposure, financing costs, and execution demands.

Which opportunities are most important?

The most important upside cases are not generic “innovation” claims. They are specific to Leidos’ mix: intelligence modernization, AI-enabled mission software, cyber operations, managed health services, integrated air defense, FAA and air traffic modernization, and energy resilience through Entrust. If these growth engines expand while Leidos maintains double-digit operating margins and converts backlog to cash, the company can support a stronger DCF than a slow-growth services multiple would imply. If execution slips, the same backlog and fixed-price exposure can produce lower-margin revenue.

Why does Leidos matter for valuation and what is the key takeaway?

Leidos matters for valuation because it combines backlog-driven revenue visibility with meaningful execution risk. A simple revenue multiple misses the point. The correct DCF drivers are contract wins, funded backlog conversion, organic revenue growth, adjusted EBITDA margin, operating cash flow, fixed-price program performance, acquisition integration, debt cost, and the durability of U.S. government mission spending. FY2025 showed a $17.174B revenue base, 12.3% operating margin, $1.750B operating cash flow, and $17.5B of net bookings. Q1 FY2026 showed 4% revenue growth, $614M adjusted EBITDA, $270M free cash flow, and a raised FY2026 outlook, but it also showed higher debt and deal-related costs.
