NAICS 541990 in Nevada: questions vendors ask

How many federal contracts under NAICS 541990 in Nevada are expiring?

They are held by 9 different vendors and were bought by 4 agencies. The figures are counted from USAspending, the government’s own record of prime contract awards, and rebuilt nightly.

When does the next NAICS 541990 contract in Nevada end?

The soonest ends on Nov 30, 2026. The table on this page lists the 10 soonest to end, in order, with the incumbent, the awarding agency, the end date and the amount obligated so far. An end date is the date in the award record, not a forecast.

Which agencies buy all other professional, scientific, and technical services in Nevada?

The agencies with the most expiring work here are Department of Defense (8 contracts), Department of the Interior (3 contracts), Department of Commerce (2 contracts). In total 4 agencies have work under All Other Professional, Scientific, and Technical Services (NAICS 541990) in Nevada ending within 12 months.

Does an expiring contract mean a recompete is coming?

Not on its own. A period of performance that ends is work somebody has to win again, but agencies also extend, consolidate, insource or cancel, and the award record does not say which in advance. Findingbase shows the dates and a renewal score built from five fixed rules, with the reasons each one fired; it does not predict the outcome and does not publish solicitations. The solicitation, when there is one, appears on SAM.gov.

How this page is built

Every contract here comes from USAspending, the federal government’s own record of prime contract awards. A contract appears when its current period of performance ends within 365 days. The table lists the 10 soonest to end — not the largest, and not the highest scoring — so it is a sample of what is really coming rather than a showcase. Award identifiers link back to the source. This page was last rebuilt for Oct 20, 2026.

10 of the 10 contracts in the table above carry a renewal score, and 15 of the 15 in the whole list do. A contract with no score has not been through scoring yet: that is not a low score, it is no score. Scoring works through the soonest expiry dates first.
