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 (3 here). Notices whose amount is a placeholder such as $999,999,999 are not added in. Revenue next to a ticker is the company's revenue over the latest 12 months in its SEC filings.
One award's total value against one year of revenue; many awards are paid over several years.
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.
