Federal contract history
| Fiscal year | Obligated, prime contracts |
|---|---|
| FY2024 | $271,714 |
| FY2025 | -$122,970 |
These are every prime contract USAspending.gov records under UEI FM8DNMBUN6R6, from its award search. For a company that is part of a parent company, USAspending's recipient page can show a different figure for a year, because it counts the company's own record and its parent's record separately.
A negative year means cuts to older contracts (de-obligations, often when work finishes under budget or is descoped) took off more than new awards added.
Its biggest federal customers since fiscal year 2024: Forest Service ($79,200) and Office of the Chief Financial Officer ($69,544).

Subcontract work reported by primes
Prime contractors reported 15 subcontracts to it worth about $1.4 million in the last five years, according to USAspending.gov. Primes only have to report subcontracts of $40,000 or more (since October 1, 2025; $30,000 before that), so smaller jobs are missing. Amounts are net of any cuts primes reported. None of this is in the prime contract figures.

How to check or correct this record
The file sometimes leaves a certification out, and a newer one won't be in it yet. Self-reported business types are what the firm says about itself on SAM.gov; they aren't SBA certifications. This page doesn't show SBA's VetCert certification for veteran-owned firms; SBA's search below does.
Check or correct this record at the source: open its SAM.gov entry, or search UEI FM8DNMBUN6R6 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications including VetCert. The business can update its details in its SAM.gov registration and its certifications at certifications.sba.gov.

Open contracts in Circinus, LLC's NAICS codes
391 open federal opportunities on SAM.gov use one of Circinus, LLC's NAICS codes and may be open to it: no set-aside, or, in the codes it is registered small under, a small business set-aside or one for a status it reports about itself on SAM.gov (service-disabled veteran-owned). Here are a few, those in its primary code first, then those in Virginia, then the soonest due.
Confirm eligibility first. Circinus, LLC's service-disabled veteran-owned status is self-reported on SAM.gov, and this page can't confirm an SBA certification for it, so set-asides for it may be relevant but may not be open to it: SDVOSB and VOSB set-asides need SBA VetCert certification. SBA's Small Business Search shows a firm's current certifications.
