Where these figures come from

Source. Every figure on this page is public federal spending data from USAspending.gov, the federal government's official record of its own spending. Public record, free to read, with no data vendor in between. Each award below links to its own record there, so any number here can be checked against the government's own page.
Scope. This record covers federal PRIME contract awards (award types A, B, C and D) published by USAspending.gov. It does not include subcontracts, grants, loans, state or local government work, commercial revenue, or any award outside the fiscal years loaded here. It is a slice of one company's federal contracting and not a complete business history — treat the totals as a floor.
Identity. Awards are grouped by Unique Entity ID (CHEUP6NNZHL9), not by name, because the same company files under several spellings and unrelated companies share names. The name shown is the spelling that appears most often on these awards, reproduced as stored.
Missing values. Where USAspending records no amount, agency, NAICS code or location, we leave it out instead of filling it in. An award with no reported amount is still counted as an award but does not enter any total or average, which is why a row's award count can outrun its dollars.
Corrections. Federal award data is revised by the agencies that report it. If something here disagrees with the linked USAspending record, the government's record is authoritative and ours is the copy that needs fixing — the link on each award is there so you never have to take our word for it.

This page reports what the federal contract award record contains. It is not a review, a rating, a recommendation or an endorsement, and nothing here is an assessment of the company or its work. We publish it because federal award history is public record and because knowing who currently holds a contract is the single most useful thing a small business can learn before bidding against them.
