Section 1 – Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

Conflict Minerals Disclosure

The Company performed a reasonable country of origin inquiry, in which it surveyed 51 direct suppliers regarding whether its necessary cassiterite, columbite-tantalite, wolframite, gold, and their derivatives, which are limited to tin and gold1 (3TG or Conflict Minerals), have been sourced from the Democratic Republic of the Congo or an adjoining country (Covered Countries). Most of the responses the Company received indicated that the 3TG in the suppliers’ components and materials either 1) were not sourced from smelters located in a Covered Country, or 2) were not necessary to the functionality of the components and materials. One direct supplier informed the Company that its 3TG (tin) originated from 100% recycled sources. Further information regarding the Company’s reasonable country of origin inquiry is included in Section 2 of the Company’s Conflict Minerals Report, which is attached to this specialized disclosure report on Form SD as Exhibit 1.01. Section 2 of the Conflict Minerals Report is incorporated by reference into this Item 1.01.

During its reasonable country of origin inquiry, the Company determined that some of its necessary Conflict Minerals may have been sourced from the Democratic Republic of the Congo or an adjoining country. As such, the Company proceeded to exercise due diligence in accordance with the Organization for Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas framework on the source and chain of custody of the Conflict Minerals. The Conflict Minerals Report includes a discussion of the due diligence procedures performed, the ultimate determination of origin and conflict status reached, and the disclosures required by the SEC. The Company has disclosed the information above, along with a copy of its Conflict Minerals Report and related materials, on its website at https://www.atmus.com/ethics-and-compliance-0.
