PepGen Inc. runs at 964% of its industry's injury rate - far more dangerous than the typical Nucleic acid chemistry research and experimental development laboratories workplace, earning a grade F.

PepGen Inc.: 4.8 TCR = 964% of Nucleic acid chemistry research and experimental development laboratories BLS 0.5 · 2y Form 300A (see methodology below)

PepGen Inc. safety composite

PepGen Inc. scores strongest on dart rate (safer than 69% of same-industry peers) and weakest on total case rate (tcr) (safer than 5%), 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).

PepGen Inc. has fewer employees than the Nucleic acid chemistry research and expe median and a higher injury rate than the industry's median TCR of 1.5. 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.
