Value counts single-winner awards. "Shared" awards are multiple-award contracts that list every winner with the same total ceiling; that ceiling is not one company's win, so it is not added in. Revenue next to a ticker is the company's last annual revenue from its 10-K.
- $LHX reported $19.4B revenue in FY2025. The median single-winner award in these 7 past awards, $17.0M, is under 0.1% of that. 10-K
