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 (2 here). Revenue next to a ticker is the company's revenue over the latest 12 months in its SEC filings.
- $RTX reported $93.5B revenue (12 months to Jun 30, 2026). The median single-winner award in these 5 past awards, $5.2M, 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.
