Cabot Microelectronics Corporation - 845: 0.8 TCR = 23% of Semiconductor devices manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Cabot Microelectronics Corporation - 845 safety composite

Cabot Microelectronics Corporation - 845 scores strongest on dart rate (safer than 77% of same-industry peers) and weakest on fatalities (safer than 51%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
