What Amentum Holdings, Inc. told the SEC could break it.
Amentum's fortunes hinge almost entirely on government demand: about 81% of fiscal 2025 revenue came from direct contracts with U.S. agencies (DoD, the Intelligence Community, NASA, DOE), and substantially all of its contracts — backing a $47.1 billion backlog — can be cancelled, terminated or suspended at the customer's discretion and depend on congressional appropriations. That exposure narrows further in specific policy areas, with a material share of work providing nuclear services to the U.S. and U.K. governments that a de-emphasis of nuclear policy would directly hurt, and 2025 U.S. trade-policy changes adding supply-chain cost and delivery uncertainty. Its other main risk is financial leverage — a SOFR-based floating-rate term loan plus $1.0 billion of 7.250% senior notes due 2032, which it has been paying down voluntarily.
5 self-disclosed vulnerabilities, pulled from its own filings — each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Regulatory & policy
- congressional appropriations / contract cancellationmedium
Substantially all contracts — backing $47.1B of backlog — are subject to cancellation, termination or suspension at the customer's discretion and contingent on congressional appropriations.
“In accordance with industry practice, substantially all of our contracts, including our U.S. federal government contracts, are subject to cancellation, termination, or suspension at the discretion of the customer, and may be subject to changes in the scope of services to be provided, as well as adjustments to the costs relating to the contracts, and may be subject to other contingencies such as congressional appropriations.”
SEC filing →As of 2025 - U.S./U.K. nuclear-policy demandmedium
A material share of contracts provides nuclear services to U.S. and U.K. governments; a policy shift de-emphasizing nuclear matters would materially harm the business.
“In addition, certain of our contracts provide a wide range of nuclear services to the U.S. and U.K. governments. If the policies of those governments were to de-emphasize nuclear matters, it may have a material adverse impact on our business, financial condition and results of operations.”
SEC filing →As of 2025 - U.S. tariffs / trade policy on supply chainmedium
New/increased U.S. and foreign tariffs under 2025 trade-policy changes create supply-chain cost and delivery-delay uncertainty for Amentum's U.S. and international operations.
“As a result of major U.S. Government trade policy changes announced by President Trump, there is currently significant uncertainty with respect to tariffs that may impact our supply chain.”
Customer concentration
- U.S. federal governmenthigh
~81% of FY2025 revenue came from direct contracts with U.S. Government agencies (DoD, Intelligence Community, NASA, DOE), making federal demand the dominant revenue driver.
“Approximately 81% of the Company's revenues were derived through direct contracts with agencies of the U.S. Government for the year ended October 3, 2025.”

Liquidity & debt
- floating-rate term loan + senior notes leveragemedium
Amentum carries a SOFR-based floating-rate Term Loan plus $1.0B of 7.250% Senior Notes due 2032; debt service depends on future performance, prompting $722M of voluntary FY2025 paydowns.
“The interest rates applicable to the Term Loan are floating interest rates equal to an Alternate Base Rate or Adjusted Term Secured Overnight Financing Rate (“SOFR”) plus an applicable margin based upon our net leverage ratio.”

We rely on Amentum to satisfy its performance obligations under these agreements.
