## Industrial safety

### Annual safety improvement followed by a September-quarter increase [casey_injuries]

FY26 and September 2026 quarter · issuer reported · high materiality

AIC reported that rolling TRIFR improved from 12.0 in June 2025 to 5.7 in June 2026, then increased to 6.2 per million hours by September 2026. Two September-quarter recordable injuries were disclosed, involving an elevated work platform and a hammer.

**Relevance:** Both the annual improvement and subsequent injury-rate increase matter for critical-control oversight.

## Evidence gaps

- Prior employer exact titles and dates remain unverified; contact-enrichment websites were not used as evidence.

- No full professional-disciplinary or employment-case database screening was completed.

- The group program and annual/quarterly TRIFR are disclosed, but June incident root causes, individual corrective-action ownership and externally verified closure were not established.

- No comparable prior-employer workforce/safety series with consistent exposure-hour denominators was found in the targeted search.

- The prior dossier and its earlier search logs were preserved separately. Prior search execution and citations not re-opened in this audit were not treated as independently verified; omitted claims require fresh source-level review.
