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.

Investor context
  • $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
  • $CTS reported $550.4M revenue in FY2025. The median single-winner award in these 7 past awards, $17.0M, is 3% of that. 10-K

One award's total value against one year of revenue; many awards are paid over several years.

Latest awards

Materiality: one award's value as a share of the winner's revenue over the latest 12 months in its SEC filings (or its last fiscal year, as noted when you point at it). Low under 1%, Medium 1 to 5%, High 5% or more. Many awards are paid over several years, so this overstates a single year's share.
