Introduction:

This is the Conflict Minerals Disclosure of Neogen Corporation (“Neogen” or the “Company”) for calendar year 2023. Certain terms in this report are defined in SEC Form SD.

If so, the registrant must conduct a Reasonable Country of Origin Inquiry (“RCOI”) that is reasonably designed to determine whether any of such Conflict Minerals originated in the Democratic Republic of the Congo (“DRC”) or any adjoining country (together with the DRC, the “Covered Countries”) or are from recycled or scrap sources.
