General	General Nature of Business On July 6, 2022, Schweitzer-Mauduit International, Inc. ("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," "we," "our", or the "Company"). Mativ is a global leader in specialty materials headquartered in Alpharetta, Georgia, United States of America.

Combined with global manufacturing, supply chain, innovation, and material science capabilities, our broad portfolio of technologies combines polymers, fibers, and resins to optimize the performance of customers' products across multiple stages of the value chain. Effective with the Merger, the Company changed the name of its two reporting segments to: Advanced Technical Materials ("ATM") and Fiber-Based Solutions ("FBS"). There was no change to the historical reporting segments or historical results for the segments. Refer to Note 16. Segment Information for additional information on our segments. We conduct business in over 100 countries and operate 48 production locations worldwide, with offices and facilities in the United States, United Kingdom, China, Germany, France, Belgium, Poland, India, Brazil, Canada, Spain, Italy, Mexico, Netherlands, Malaysia, and Luxembourg. Basis of Presentation The accompanying unaudited condensed consolidated financial statements and the notes thereto have been prepared in accordance with the instructions on Form 10-Q and Rule 10-01 of Regulation S-X of the Securities and Exchange Commission ("SEC") and do not include all the information and disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP"). However, such information reflects all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of results for the interim periods. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the full year. The unaudited condensed consolidated financial statements and these notes thereto included herein should be read in conjunction with the audited consolidated financial statements and the related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 1, 2022. Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned, majority-owned and controlled subsidiaries. The Company’s share of the net income of its 50%-owned joint ventures in China is included in the unaudited Condensed Consolidated Statements of Income/(Loss) as Income from equity affiliates, net of income taxes. Intercompany balances and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures of contingent assets and liabilities in the unaudited condensed consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, inventory valuation, useful lives of tangible and intangible assets, business acquisitions, equity-based compensation, derivatives, sales returns and rebates, receivables valuation, pension, postretirement and other benefits, restructuring and impairment, taxes and contingencies. Recently Adopted Accounting StandardsIn March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The new standard provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform and the anticipated discontinuance of the London Interbank Offered Rate ("LIBOR") if certain criteria are met. The amendments in this ASU are effective for all entities as of March 12, 2020, through December 31, 2022. We adopted this ASU as of April 1, 2022 with no material impact to our financial statements.
