Why this number?

Amounts are obligations (money committed), not outlays (money paid).
Location is where the work is performed, not where the recipient is based.
Medicare payments are published as aggregate records placed where Medicare's claims contractors are (mostly Minnesota, Indiana, Pennsylvania, Kentucky, North Dakota, Connecticut, Florida and South Carolina), not where patients live, so those states show far more HHS money than their population suggests (ask for Medicare payments by patients' home state for where beneficiaries live).
'(outside the US)' is work performed abroad; '(not reported)' has no location in the source.
Company roll-ups match names and parent companies; some subsidiaries may be missed.

$72.86MOther than small (large)

Top 1 by obligations in FY2026. Leading: Other than small (large) ($72.86M).

Business type	Obligations
Other than small (large)	$72.86M

Why this number?

Amounts are obligations (money committed), not outlays (money paid).
Business types are the vendor's status as certified for each contract action (small or other than small, woman-owned, veteran-owned, 8(a), HUBZone...). They overlap (a firm can be small, woman-owned and 8(a) at once), so they don't add up to the total. This is who got the money, not whether the contract was set aside.
Contracts only (industry, product, set-aside and business-type details exist only for contracts).
Company roll-ups match names and parent companies; some subsidiaries may be missed.
