Federal contract history
| Fiscal year | Obligated, prime contracts |
|---|---|
| FY2024 | $1.1 million |
| FY2025 | $2.5 million |
| FY2026 (incomplete) | -$150,035 |
FY2026 is still incomplete and will rise until about early January 2027 as Defense data arrives: USAspending.gov publishes Defense contracts 90 days after they're signed.
These are every prime contract USAspending.gov records under UEI VMLJB3E2LLT6, 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: Department of the Army ($3.7 million), Public Buildings Service ($94,576) and Department of the Navy ($57,728). USAspending.gov works out these by-agency figures separately from the yearly totals, so they can come to a little more than the total above.
