Red flag score: 84 / 100 · very high

Computed only from the verified red flags below: each flag earns points for its severity, loses half its weight every 180 days, and companies with several different flag types in the past year get a bonus. Total points 91.3 → score = 100 × (1 − e−points/50) = 84. Full method
