Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

Atkore Inc. (“Atkore” or the “Company”), together with its subsidiaries support the responsible sourcing of materials and are committed to working with our suppliers to ensure compliance with government regulations. Atkore follows a standard process to review all of our product lines in order to comply with the regulations of the Securities and Exchange Commission ("SEC"). While the current review for the 2023 calendar year and prior reviews do not indicate probable use of conflict minerals sourced from the Democratic Republic of the Congo ("DRC") that are essential to the functionality of our products, we will continue to conduct comprehensive reviews of our suppliers to determine their possible use of conflict minerals in the materials they supply to our Company. Our standard terms and conditions require suppliers to Atkore to be “conflict-free,” meaning they do not supply materials that contain 3T/G sourced from the DRC or adjoining countries.

As provided for in Rule 13p-1 under the Securities Exchange Act of 1934, as amended, and Form SD, a Conflict Minerals Report is provided as an Exhibit to this Form SD and is available on our website at https://investors.atkore.com. For inquiries concerning Conflict Minerals, please contact industryaffairs@atkore.com.
