Direct is the company's own reviewed UEIs. Reported by USAspending is subsidiaries as reported by USAspending: recipients that name this company as their parent, not yet reviewed ownership.

Directly matched recipients (up to 12)

UEIs matched to this organization, largest obligations first. Subsidiary recipients are not included in this list; their attributed obligations can appear in the company totals above.

Each action is credited by the ownership basis shown in its column. Reported-parent rows count for ThayerMahan only for the period a subsidiary reported ThayerMahan as its parent; reviewed links follow their reviewed dates. Net of de-obligations; these are obligations, not ceilings. They come from the whole USAspending baseline (every recipient size, contracts and assistance) and are a separate view from the curated contract totals on this page. FY2026 and later are partial, as on Markets.
