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.

Check or correct this record at the source: open its SAM.gov entry, or search UEI QV6NLEHN4Y26 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications including VetCert.
