The verdict

Lumentum Corporate runs at 4% of its industry's injury rate - far safer than the typical Semiconductor devices manufacturing workplace, earning a grade A.

Lumentum Corporate: 0.1 TCR = 4% of Semiconductor devices manufacturing BLS 3.3 · 3y Form 300A (see methodology below)

Lumentum Corporate safety composite

Lumentum Corporate scores strongest on total case rate (tcr) (safer than 95% of same-industry peers) and weakest on dart rate (safer than 49%), 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).

Lumentum Corporate (650 employees, TCR 0.1) among 29 same-industry peers, split at the industry median of 216 employees and a TCR of 0.9

Lumentum Corporate has more employees than the Semiconductor devices manufacturing median and a lower injury rate than the industry's median TCR of 0.9. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
