Leidos (LDOS): What This Company Actually Does

How Leidos makes money

Leidos designs, builds, and operates the systems the U.S. government — mostly the Department of Defense and intelligence agencies — needs but doesn't build itself: cyber defense, reconnaissance hardware, space and maritime systems, and health-data processing. Its own engineers and scientists do the work directly, and the government pays out of its annual budget.

Where the revenue comes from

Revenue by segment — FY2025

National Security & Digital
$7.61B (44%)
Health & Civil
$5.07B (30%)
Commercial & International
$2.32B (13%)
Defense Systems
$2.18B (13%)

Health & Civil is the most profitable segment at 23.7% operating margin, versus 10.0% for National Security & Digital and 7.2% each for the other two. Source: 10-K FY2025, Note 20.

Reading the geography International revenue is a thin 8.2%, mostly from Australia and the U.K., so currency risk is limited. The real concentration is that 87% of revenue ultimately comes from the U.S. federal budget — the risk here is Washington's budget calendar and politics, not exchange rates.

Customers and competitors

Leidos sells almost exclusively to government: 49% to defense and intelligence agencies, 38% to other federal and state agencies, and just 13% to commercial and international customers.

  • Booz Allen Hamilton — stronger in consulting-oriented intelligence and cyber advisory work.
  • SAIC — the closest direct competitor by scale and customer base.
  • CACI International — focused on specific defense niches like signals intelligence and electronic warfare.

The metric that matters most in this sector

For a government-services contractor, revenue can be lumpy quarter to quarter, but backlog — contracts already won — tells you what's coming one to two years out. If backlog grows faster than revenue, that's a signal growth will continue.

Of the $49B total, $9.7B (about 20%) is funded backlog with budget already appropriated; the rest depends on option exercises. Total backlog is now about 2.8 times FY2025 revenue. Source: 10-K FY2021–FY2025.

Leadership and ownership

CEO Thomas A. Bell took over in May 2023, about three years ago, arriving from Rolls-Royce North America (chairman and CEO) and before that a career in Boeing's defense sales organization — a professional executive with no ties to founder Robert Beyster, who founded the company in 1969 and is no longer involved. Insider ownership is thin at 0.77%; the largest shareholders are institutional index managers Vanguard (about 12.2%) and BlackRock (about 6.8%).

Capital returns

Leidos pays a dividend yielding 1.33% ($1.72 annually), with the per-share payout rising from $1.54 in FY2024 to $1.63 in FY2025, up 5.8%. Buybacks have grown sharply — from $250M in FY2023 to $910M in FY2024 to $940M in FY2025 — and shares outstanding actually fell 3.7% over the year (131.2M to 126.4M), meaning the repurchases are genuinely retiring shares rather than just offsetting new stock-based compensation. A 20-million-share buyback authorization was approved in February 2022.

How this company could fail

Failure scenario If a federal budget crisis or prolonged shutdown forces sharp cuts to defense and intelligence spending, the customer base that accounts for 87% of Leidos's revenue closes its wallet all at once.
  • Federal budget and debt-ceiling risk — defense and intelligence agencies alone are 49% of revenue; budget caps or debt-ceiling standoffs can delay contract awards directly.
  • Contract termination and bid-protest risk — the government can terminate contracts "for convenience" at any time, and competitors can delay large awards by filing bid protests.
  • Cybersecurity and data-breach risk — handling sensitive defense and intelligence data means a security incident could mean an immediate loss of trust-dependent contracts.

Worth noting FY2023's operating-income drop wasn't an operating problem — it was a one-time $596M goodwill impairment in the Commercial & International segment's airport-security-equipment business. Free cash flow actually rose that same year, which is why it's worth separating accounting charges from real cash generation here.

What we still don't know

  • How the January 2026 Entrust acquisition ($2.4B, funded with a $1.4B bridge loan) will affect leverage and margins once it closes isn't visible in this 10-K alone.
  • How segment profitability shifts under the FY2026 reorganization into Intelligence & Digital, Health, Homeland, and Defense — replacing the current four segments — needs to be checked against upcoming quarterly filings.
  • The status and outcome of a 2022 DOJ antitrust criminal investigation (grand jury subpoena) isn't disclosed in enough detail to determine here.
