EXPLANATORY NOTE

DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 (this “Post-Effective Amendment”) to the Registration Statement of Enviri Corporation (the "Company") on Form S-3 (File No. 033-56885), originally filed with the Securities and Exchange Commission on December 15, 1994 (such Registration Statement, including as amended on January 12, 1995, the “Registration Statement”), is being filed to deregister any and all securities that remain unsold under each such Registration Statement as of the date hereof.

Reference is made to (i) an Agreement and Plan of Merger, dated as of November 20, 2025 (the “Merger Agreement”), by and among the Company, CLEH, Inc. (“CLEH”), Enviri LLC (“Enviri LLC”), Veolia Environnement S.A. (“Buyer”), and Liberty Merger Sub Inc. (“Merger Sub”), and (ii) a Separation Agreement, dated as of November 20, 2025 (the “Separation Agreement”), by and among the Company, CLEH, Buyer, and Enviri II Corporation (“New Enviri”).

On June 1, 2026, pursuant to the terms of the Merger Agreement and the Separation Agreement: (i) the Company merged with and into Enviri LLC, with Enviri LLC being the surviving entity of such merger, and each outstanding share of Common Stock exchanged for one share of common stock, par value $1.25 per share, of CLEH (the “Holding Company Merger”); (ii) following the Holding Company Merger, CLEH and its subsidiaries, including Enviri LLC and New Enviri, effected a reorganization (the “Reorganization”), resulting in (x) CLEH holding the Clean Earth segment of the Company and owning all the outstanding shares of common stock, $0.00001 per share, of New Enviri ("New Enviri Common Stock"), (y) New Enviri owning all of the equity interests of Enviri LLC and (z) Enviri LLC holding the Harsco Environmental and Rail segments of the Company; (iii) following the Reorganization, CLEH distributed all of the outstanding shares of New Enviri Common Stock to the stockholders of CLEH (the former stockholders of the Company) on a pro rata basis (the “Distribution”); and (iv) immediately after the Distribution, Merger Sub, a wholly owned subsidiary of Buyer, merged with and into CLEH, with CLEH surviving as an indirect wholly owned subsidiary of Buyer.

As a result of the Holding Company Merger and the other transactions contemplated by the Merger Agreement and the Separation Agreement, the Company has terminated all offerings of the Company’s securities registered pursuant to its existing registration statements under the Securities Act of 1933, as amended, including the Registration Statement. Enviri LLC, as successor by merger to the Company, by filing this Post-Effective Amendment, hereby terminates the effectiveness of the Registration Statement and removes from registration any and all securities registered for issuance under the Registration Statement that remain unsold as of the date hereof. This filing is made in accordance with an undertaking made by the Company in the Registration Statement to remove from registration by means of a post-effective amendment any securities that had been registered for issuance that remain unsold at the termination of the offering.
