Q4 FY2026 · partial6$6.0M-14%

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.
