Who won similar work

15 award notices on SAM.gov in the last 24 months. Matched by: Same agency (National Park Service), same product/service code (PSC) F108.

Single-winner award sizes (15): middle half $25K to $519K, median $72K; range $8K to $2.3M.

Value counts new single-winner awards. "Shared" awards are multiple-award contracts that list every winner with the same total ceiling (same contract, or the same office, day and amount); that ceiling is not one company's win, so it is not added in. Contract modifications are not new awards and are not added in either. Revenue next to a ticker is the company's revenue over the latest 12 months in its SEC filings.
