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.

Investor context
  • $IBM reported $69.1B revenue (12 months to Jun 30, 2026). The median single-winner award in these 10 past awards, $81.2M, is 0.1% of that. SEC filing

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.
