The verdict

MACOM Ann Arbor runs at 24% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

MACOM Ann Arbor: 0.8 TCR = 24% of Semiconductor devices manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

MACOM Ann Arbor safety composite

MACOM Ann Arbor 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).
