The Department of Defense's NAICS 541990 (All Other Professional, Scientific and Technical Services) market: incumbents, spending trend, set-asides and open solicitations — from FY2026 USAspending awards and live SAM.gov notices.
Contract data as of Oct 18, 2026 (USAspending) · recent coverage verified weekly
| Quarter | Awards | Obligated | Change |
|---|---|---|---|
| Q1 FY2026 | 134 | $891.5M | — |
| Q2 FY2026 | 182 | $387.9M | -56% |
| Q3 FY2026 | 34 | $90.5M | -77% |
| Q4 FY2026 · partial | 53 | $267.9M | +196% |
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.
| # | Contractor | Obligated | Share |
|---|---|---|---|
| 1 | THE MITRE CORPORATION | $622.8M | 38.0% |
| 2 | LOCKHEED MARTIN CORP | $318.1M | 19.4% |
| 3 | INSTITUTE FOR DEFENSE ANALYSES | $108.5M | 6.6% |
| 4 | SIERRA NEVADA COMPANY, LLC | $90.9M | 5.6% |
| 5 | THE RAND CORPORATION | $44.2M | 2.7% |
Registrations are rolled up to their corporate parent (USAspending parent UEI), so a company with several SAM registrations ranks once.

| 8(a) | $21.1M | 1.8% |

Share of obligations on awards whose set-aside type is recorded — 73% of this market's dollars. Most USAspending bulk-archive records leave the field blank, so blank awards are excluded rather than counted as full & open.
