Contracts with the US government

What the federal government committed in contracts to the company and its subsidiaries, by federal fiscal year (October to September).

$821M Fiscal year 2025

In federal fiscal year 2025 (October 2024 to September 2025) the US government committed $821M in contracts to the company and its subsidiaries. The year before it was $1.1B. That is about 15% of its revenue in the fiscal year to September 28, 2025 ($5.4B), though an amount committed is not revenue.

From USAspending.gov, the federal government's public spending records, as of November 1, 2026. An amount committed is not revenue of the same year: a contract running several years counts when it is signed, and the company is paid as it does the work. The company is matched through the parent company the government records it under, which adds up its subsidiaries. A subsidiary recorded under another parent can be missing.
