Refer to Note 10, "Litigation," for information regarding legal proceedings in which we are involved.

Workplace safety

OSHA Form 300A summaries, 2019–2025

Larger establishments and those in higher-hazard industries must send OSHA a summary of their work-related injuries and illnesses each year (29 CFR 1904.41). These are the summaries filed under PLEXUS CORP’s Employer Identification Number — 3 establishments in 2025, not the whole organization.

These are summaries the employer submitted about itself — not OSHA inspections, citations or findings. Only establishments over the reporting threshold appear, so this covers part of an organization rather than all of it, and an employer with no summaries here is usually one that was never required to file. The Employer Identification Number is entered by the employer and is not verified by OSHA against IRS records. The rate is calculated from the two figures above using OSHA’s formula — cases × 200,000 ÷ hours worked, where 200,000 is 100 employees working a full year. Data as published by OSHA in May 2026.
