Q4 FY2026 · partial20$16.4M-83%

Federal fiscal quarters (Q1 = Oct–Dec). Awards are counted in the quarter they start; obligations are the award's obligated amount. The Department of Defense publishes contract awards to USAspending with a 90-day delay, so Q4 FY2026 is still missing most DoD awards — treat that quarter as incomplete, not as a spending decline.

Registrations are rolled up to their corporate parent (USAspending parent UEI), so a company with several SAM registrations ranks once.
