Scope and comparison rules
The latest period runs from Oct 24, 2025 through Oct 23, 2026. It is compared with Oct 24, 2024 through Oct 23, 2025.
Rankings cover this page’s 113 published profiles. A profile must contain at least 10 positive-obligation awards in each period, at least $1M in preceding-period net obligations, nonnegative latest-period net obligations, and at least $1M of absolute movement to appear.
Net obligations include deobligations and corrections. A historical increase or decline does not establish market attractiveness, requirement demand, future buying intent, or a forecast. Green and red indicate direction only, not favorability.
