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.
- $GD reported $53.8B revenue (12 months to Apr 5, 2026). The median single-winner award in these 21 past awards, $2.5M, is under 0.1% of that. SEC filing
One award's total value against one year of revenue; many awards are paid over several years.
