QUEST DIAGNOSTICS INC

Its government footprint in one place: federal money, influence and market activity, each row linked to its source. Federal figures gathered Oct 25, 2026.

In plain words

The federal government obligated $70.0M in contracts to QUEST DIAGNOSTICS INC in the 12 months to Sep 2026, about 0.59% of its revenue over the same months. The most came from Department of Veterans Affairs. 1 of its contracts, with $10.1M obligated on them so far, end in the next 18 months and may be competed again. It appears on 46 Senate lobbying filings from 2023 to 2026; 20 of the lobbyists on them once held government posts. In the last 12 months insiders sold 5 times ($15.4M) and bought 0 times ($0); 3 of the 3 sales whose filing shows the plan box were planned in advance.

What these numbers are

Obligated means an agency committed the money to this company in that period (a signed contract action), as reported to USAspending. It is not a payment and not revenue: a contract can be funded for several years at once, and revenue is booked as the work is done. Some years can exceed revenue for that reason.

Prime contracts only, and only what is published. Work the company does as a subcontractor is not in these figures, and classified contracts are not published on USAspending at all. A low share can mean either. Contract values, ceilings and options are never added in.

Which units count: the USAspending recipient that is the company's SEC registrant; units of the company that USAspending's own records place under it (as parent, or in its family tree); and subsidiaries from the company's SEC Exhibit 21 that carry its name. Joint ventures, units now owned by someone else, and records that only share a name are held back. Both lists are below.

Earlier years count the units the company owns today. A unit we checked by hand (its USAspending parent is out of date) counts from the date the company bought it, or, where no filing gives that date, from the first date a filing shows the company owning it. Other units count for every year shown until their purchase dates are loaded.

Revenue bars are the company's own fiscal year from its 10-K, placed in the federal year it ends in; its fiscal year can end in a different month than the government's.

Fiscal year 2022 onward. Federal fiscal years run October to September; the company's own fiscal year may differ.

Units counted (19), held back (23)

Held back: a matching name we could not tie to this company firmly enough. A miss is better than a wrong link.
