**Section 1 - Conflict Minerals Disclosure**

**Item 1.01 Conflict Minerals Disclosure and Report**

In accordance with the disclosure requirements promulgated by the U.S. Securities and Exchange Commission ("SEC"), Enviri Corporation ("we," "our," "Enviri," or the "Company") has undertaken efforts to determine the Company's conflict minerals reporting requirements<sup>1</sup> for the period from January 1 to December 31, 2025. The Company is a market-leading, global provider of environmental solutions for industrial and specialty waste streams and innovative equipment and technology for the rail sector. Our three reportable business segments are Harsco Environmental, Clean Earth and Harsco Rail. The Company was incorporated in 1956 and has locations in over 30 countries, including the U.S.

We are subject to this rule as we have determined that, during 2025, conflict minerals were likely necessary to the functionality or production of products we manufactured or are contracted to manufacture. The Company, as a purchaser of component parts, is several steps removed from the mining of conflict minerals. We do not purchase raw ore or unrefined conflict minerals and we conduct no purchasing activities directly in the DRC or adjoining countries.

The Company has developed a policy statement to support the goals expressed by Congress in enacting Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The policy highlights the Company's commitment to complying with the reporting and due diligence obligations required by SEC rules and regulations, and the Company's expectations from its suppliers. In addition, the policy includes language encouraging suppliers to source responsibly. The policy resides on our corporate website (https://www.enviri.com/sustainability). The information on the Company's website does not constitute part of this Form SD.

We have conducted a good faith reasonable country of origin inquiry ("RCOI") to determine whether the necessary conflict minerals originated in the DRC or an adjoining country or came from recycled or scrap sources.

We began our RCOI by identifying product categories and consumables that may contain conflict minerals. Initial product categories and consumables within this scope included fittings, paint, motors, coatings, air motors, admiralty brass, pipes, welding wire, wire, electrical fittings, lubricants, glass, bushings, electronics, cables, steel parts, fabricated parts, machine parts, castings, hydraulic parts, bearings, power transmissions and tubular parts. Using information derived from Enviri's procurement systems, supplemented by information supplied by personnel in Enviri's divisional supply chain, we produced a list of direct suppliers of components and raw materials that may contain conflict minerals. We then conducted a good faith RCOI to determine whether the necessary conflict minerals originated in the DRC or an adjoining country or came from recycled or scrap sources. Our RCOI process included conducting an inquiry of our direct suppliers using the Responsible Minerals Initiative's Conflict Minerals Reporting Template ("CMRT"). We sent reminders to those suppliers that did not respond to our request to complete a CMRT. Based on the results of our RCOI, which indicated sourcing from the covered countries, we exercised due diligence on the source and chain of custody of the conflict minerals in accordance with the Organization for Economic Co-operation and Development framework<sup>2</sup>.

The Company has elected not to file disclosure under Item 1.01(c) of Form SD in accordance with the "Updated Statement on the Effect of the Court of Appeals Decision on the Conflict Minerals Rule" issued by the Division of Corporation Finance of the SEC on April 7, 2017.

<sup>1</sup> The term "conflict mineral" is defined in Section 1502(e)(4) of the Dodd-Frank Wall Street Reform and Consumer Protection Act as (A) columbite-tantalite, also known as coltan (the metal ore from which tantalum is extracted); cassiterite (the metal ore from which tin is extracted); gold; wolframite (the metal ore from which tungsten is extracted); or their derivatives; or (B) any other mineral or its derivatives determined by the Secretary of State to be financing conflict in the Democratic Republic of the Congo ("DRC") or an adjoining country.
