Section 1—Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

I. Overview

ATI Inc. (“ATI”) is a global producer of high performance materials and solutions for the global aerospace and defense markets, and critical applications in electronics, medical and specialty energy.

We have adopted a conflict minerals policy that is publicly available on our website at www.ATImaterials.com at “About ATI – Suppliers.” This Form SD is available at the “Investor Relations” page of our website, www.ATImaterials.com.

II. Conflict Minerals Disclosure

Based on ATI’s procedures described below, for products that we manufactured in 2022 the responses to ATI’s Reasonable Country of Origin Inquiry during the 2022 calendar year reporting period gave ATI no reason to believe that any tin, tungsten, tantalum or gold not from scrap or recycled sources that are intentionally added and necessary to the functionality or production of our products (“necessary conflict minerals”) originated in the Democratic Republic of the Congo or adjoining countries (the “Covered Countries”).

A. Conflict Minerals Procedures

With respect to 2022 production, ATI continued to utilize the risk-based approach that it established beginning for 2013, which consists of the following three main elements:

1. Product Risk Assessment:

All ATI business units performed a conflict minerals product risk assessment. This process required a review by qualified employees of material specifications and product requirements to determine which ATI products, in their manufacture, include necessary conflict minerals. This assessment considered all materials that become part of a final product. Each ATI business unit is required to maintain a narrative describing this assessment process and a product risk matrix that lists information about the products that include necessary conflict minerals. The product risk assessment is also conducted by the business units as new products are developed.

2. Supplier Risk Assessment

All ATI business units that manufacture products that include necessary conflict minerals performed a supplier risk assessment, which consisted of the identification of (i) all purchased materials that include necessary conflict minerals, and (ii) all suppliers of these materials. This assessment considered all materials that become part of a final product. Once the purchased materials and suppliers were identified, each business unit determined whether the necessary conflict minerals were from scrap or recycled sources. This supplier risk assessment was performed by qualified individuals and included review of applicable material specifications, purchasing records, and other documentation. The supplier risk assessment is also conducted as new suppliers are evaluated.

Each ATI business unit that performed the supplier risk assessment is required to maintain a narrative describing this assessment process and a supplier risk matrix that lists information about the suppliers and purchased materials.

3. Reasonable Country of Origin Inquiry (“RCOI”)

Once ATI identified the necessary conflict minerals in our supply chain that were not from scrap or recycled sources, ATI requested a completed Conflict Minerals Reporting Template (“CMRT” – available at http://www.responsiblemineralsinitiative.org /), at the product level, from each supplier of materials containing necessary conflict minerals. In addition, ATI requested that each supplier provide the country(ies) of origin of the necessary conflict minerals and supporting documentation from applicable smelters with the completed CMRT. Letters or statements from suppliers in support of or in place of a CMRT were also accepted as deemed appropriate.

All completed CMRTs and other responses were reviewed for completeness, consistency of information, and overall reasonableness. Further inquiry and engagement with suppliers was performed as deemed necessary to obtain additional or complete information or clarification.

Additionally, in further support of ATI’s RCOI process, direct/first tier suppliers of materials containing non-scrap/non-recycled necessary conflict minerals were screened using a third party online screening database to determine if there were any “red flags” (such as inclusion on regulatory watch lists/sanction lists or adverse media articles) which could cause us to question any RCOI information provided by the supplier. Supplier screening and resolution of any potential “red flags” were documented as part of the RCOI process. Following the initial screening, suppliers are monitored on an ongoing basis using this screening tool, and any potential supplier “red flags” that are raised will continue to be reviewed and resolved and additional actions will be taken with suppliers as required.

B. Results of RCOI for 2022

We believe that we have identified all of the products that we manufactured in 2022 that contain necessary conflict minerals and have identified all suppliers that provided us with non-scrap/non-recycled materials containing necessary conflict minerals in 2022.

In all cases, these suppliers provided us with a completed CMRT or other reasonable response, and appropriate information relating to the country(ies) of origin of the necessary conflict minerals. Furthermore, in accordance with our described RCOI process, any potential “red flags” raised in the suppliers’ responses were investigated and resolved.

With respect to the period covered by this report, calendar year 2022, the responses from our suppliers, our review of this information and additional investigatory measures taken as needed, as described in Part II.A.3. of this report, gave ATI no reason to believe that, in the manufacture of our products in 2022, non-scrap/non-recycled necessary conflict minerals originated in the Covered Countries.

III. Mitigating Conflict Minerals Risk

ATI has procurement controls for purchasing materials that contain necessary conflict minerals, which include completion of the RCOI process at the time that a supplier is on-boarded, flowing-down conflict minerals requirements to applicable suppliers, and implementing standard purchase terms and conditions to address conflict minerals compliance. In addition, within our supply chain, we continue to communicate ATI’s conflict minerals policy requirements and our expectations of our suppliers, as set forth on the “About ATI – Suppliers” page of our website, www.ATImetals.com. These measures reflect ATI’s ongoing commitment to full compliance with Section 1502 of the Dodd-Frank Act and supply chain transparency.
