EXPLANATORY NOTE

This Amendment No. 1 on Form 11-K/A (this “Amendment”) of Schweitzer-Mauduit International, Inc. ("SWM" or the “Company”) amends the Company’s Annual Report on Form 11-K of Schweitzer-Mauduit International, Inc. Retirement Savings Plan for the year ended December 31, 2021 (the “Annual Report”), originally filed with the Securities and Exchange Commission on July 13, 2022 (the “Original Filing Date”). This Amendment is being filed solely for the purpose of: (1) including this Explanatory Note, (2) indicating in the Notes that registrant consummated its previously announced merger transaction subsequent to the Annual Report; and (3) indicating that the Chief Human Resources Officer for the Schweitzer-Mauduit International, Inc. Retirement Savings Plan changed when the registrant consummated its previously announced merger transaction.

On July 6, 2022, SWM consummated its previously announced merger transaction involving Neenah, Inc. ("Neenah"). A wholly-owned subsidiary of SWM merged with and into Neenah (the "Merger"), with Neenah surviving the Merger as a direct and wholly-owned subsidiary of SWM. Effective as of the closing date of the Merger, SWM changed its name to Mativ Holdings, Inc. (“Mativ”). The name of the Schweitzer-Mauduit International, Inc. Retirement Savings Plan (the “Plan”) did not change as a result of the Merger. SWM will subsequently be referred to as Mativ and the SWM Stock Fund will subsequently be referred to as the Mativ Stock Fund.

Although this Annual Report on Form 11-K/A is filed after the completion of the Merger, unless otherwise specifically noted herein, information set forth herein is as of and for the period ended December 31, 2021; and, therefore, does not include the information of Neenah. Accordingly, unless otherwise specifically noted herein, references herein to "the Company" refer only to Mativ and its subsidiaries prior to the Merger and do not include Neenah and its subsidiaries.

In addition, effective as of the Merger on July 6, 2022, the Chief Human Resources Officer for the Plan changed from Mari Sifo to Mike Rickheim. As such, this Annual Report on Form 11-K/A is signed by Mike Rickheim.

This Amendment consists solely of this Explanatory Note, the Subsequent Events Note, and the Signatures page.

Other than as expressly set forth above, this Amendment does not, and does not purport to, amend, update or restate the information in the original filing of the Annual Report or reflect any events that have occurred after the original filing was made on July 13, 2022. No changes have been made to the financial statements of the Company as contained in the original filing of the Annual Report. Accordingly, this Amendment should be read in conjunction with the Original Report and the Company’s other filings with the Securities and Exchange Commission.
