A government shutdown does not hit every federal contractor the same way. When appropriations lapse, agencies without funding generally cannot sign new contracts or orders, and work that needs federal staff or federal sites can stop. The companies with the most direct exposure are those that get a large share of revenue from Washington and whose contracts come mainly from civilian agencies rather than the Department of Defense.
By that test, Science Applications International and Leidos stand out. Science Applications International reports 98% of its revenue from the U.S. government, and civilian agencies awarded 53.4% of its federal contract obligations in federal fiscal year 2025. Leidos reports 87% of its revenue from the U.S. government, and civilian agencies awarded 57.2% of its federal contract obligations. Maximus depends less on the federal government overall, at 55% of revenue, but 99.8% of its federal contract obligations came from civilian agencies.

Why the agency matters
Congress funds the government through a set of separate appropriations bills. Defense has its own bill; civilian departments are spread across the others. When some bills pass and others don't, only the agencies under the unpassed bills lose funding. Much defense procurement and research money is also appropriated to stay available for more than one year, so contracts already funded with earlier money can often keep going. Many civilian operating accounts must be used within the year.
None of this makes defense contractors immune. If the defense bill lapses too, the Pentagon faces the same legal limits as every other agency. But a civilian-agency contractor is exposed whenever its agencies' bills lapse, whether or not defense is funded. Every lapse is different: which agencies close, for how long, and which activities are exempt depend on the bills in force at the time. See the glossary for the legal mechanics.
What we measure. "Civilian share" is the part of a company's matched prime contract obligations in federal fiscal year 2025 awarded by any agency other than the Department of Defense. Obligations are commitments to pay, not revenue: they can cover several years of work and arrive in lumps. The measure shows where a company's contracts come from. It does not predict how much revenue a shutdown would cost.
Both measures, side by side
The table lists every company we cover, ranked by the civilian share of its contract obligations. The reported share is the company's own figure for revenue from the U.S. government. Companies marked † have a contract match we are still reviewing, so their agency mix is less certain.

What the table shows
Civilian-agency contractors. Maximus, ICF International, Leidos, Science Applications International and Fluor each get more than half of their contract obligations from civilian agencies and disclose a U.S. government share. Maximus is the clearest case. The Department of Veterans Affairs accounts for more of its contract obligations than any other agency, and almost none of its federal contract money comes from the Pentagon. Its 10-K also shows how much of its business sits with other levels of government: "In fiscal year 2025, approximately 55% of our total revenue was derived from the U.S. federal government, and approximately 33% of our total revenue was derived from contracts with state …" That part of its revenue is not paid directly by federal agencies, although some state programs draw on federal money.
Booz Allen Hamilton and Parsons get most of their obligations from civilian agencies too, but neither discloses a company-wide U.S. government share. Booz Allen's 10-K says "substantially all" of its revenue comes from the U.S. government without giving a percentage; we show both as "not disclosed" rather than estimate.
Mixed portfolios. CACI International, Palantir, Amentum and KBR get between 22.8% and 42.1% of their obligations from civilian agencies. Their exposure depends heavily on which bills lapse. Amentum's civilian work is concentrated at the Department of Energy; KBR's at NASA.
Defense-heavy companies. Leonardo DRS, Oshkosh, TransDigm, Lockheed Martin, RTX, Textron, Boeing and Huntington Ingalls get 90% or more of their contract obligations from the Department of Defense. For them, the question in any funding fight is whether the defense bill has passed. Their overall dependence varies widely, from 99.9% of revenue at Huntington Ingalls to 20% at Oshkosh.
BWX Technologies shows one of the highest civilian shares, almost all of it from the Department of Energy. Its contract match is under review, because matched obligations are far below the government revenue it reports, so we don't draw conclusions from its mix yet.
One caveat: who signs is not who pays
Our civilian share counts the agency that signed the contract. That is not always the agency whose budget pays for the work. The General Services Administration (GSA), through its Federal Acquisition Service, often buys on behalf of other agencies, including the Department of Defense. GSA signed 31.4% of Booz Allen Hamilton's obligations, 24.6% of CACI International's, 23.2% of Science Applications International's, and 17.5% of Parsons'. For these companies the civilian share may overstate exposure to civilian budgets. The records we use do not show, contract by contract, whose money it was.
What this doesn't tell you
- How much revenue a shutdown would cost. That depends on its length, which activities are exempt, stop-work orders on individual contracts, and how much work was funded before the lapse.
- Subcontract work. Revenue a company earns as a subcontractor shows up in another company's prime contracts, not its own. Leidos and CACI, among others, say their reported share includes such work.
- Anything about a particular year. The agency mix covers one federal fiscal year, 2025, and a single large award can move it.
The point is narrower: a company that gets most of its revenue from Washington, through civilian agencies, has more of its business tied to agencies that lose funding whenever a civilian bill lapses. That is a description of exposure, not a forecast. Rankings by reported share for every company are on the rankings page.
How we did this
For each company we took the share of revenue its latest 10-K attributes to the U.S. government, as reported. From USAspending.gov we took prime contract obligations to the recipients we matched to the company in federal fiscal year 2025, grouped by awarding agency, and calculated the share awarded by agencies other than the Department of Defense. Matching rules are on the methodology page.
