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.

See every expiring NAICS 237110 at Department of Defense contract in the Recompete Tracker →

Contracts with at least $250K obligated whose final end date — every option exercised — falls in the window, counted from Oct 31, 2026. These are the Recompete Tracker's default filters (18 months, ≥$250K), so the figures match the tracker for NAICS 237110 at Department of Defense. “Obligated to date” is what has been obligated on the contract so far, not the value of the follow-on. An end date is when the work stops, not when the replacement is solicited — that usually happens 6–18 months earlier. Source: USAspending.gov prime awards.

From FPDS fields on contract awards that started in FY2026. Offers received is recorded on 49% of these 148 awards and extent competed on 100% — much of the USAspending bulk archive leaves both blank — so each share is over the awards where the field is recorded, not all awards. FPDS's placeholder count of 999 offers is excluded. Task orders under multiple-award vehicles often report the vehicle's offer count, which inflates averages; the single-offer share is the steadier signal. “Not competed” = not competed, not competed under simplified acquisition, or not available for competition (sole-source authorities, including 8(a) directed awards).

Registrations are rolled up to their corporate parent (USAspending parent UEI), so a company with several SAM registrations ranks once. Track record: fiscal years FY2015–FY2024 in which the company family received prime awards from any agency (USAspending.gov, by UEI; earlier years aren't loaded), and how many of those years Department of Defense was its largest customer by dollars. Awards and obligations in this table are FY2026.
