Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General Nature of Business Organization and operations - Mativ Holdings, Inc. is a global leader in specialty materials, solving our customers’ most complex challenges by engineering bold, innovative solutions that connect, protect, and purify our world. Mativ manufactures globally through our family of business-to-business and consumer product brands. Mativ targets premium applications across diversified and growing end-markets, from filtration to healthcare to sustainable packaging and more. Our broad portfolio of technologies combines polymers, fibers, and resins to optimize the performance of our customers’ products across multiple stages of the value chain. On July 6, 2022, Schweitzer-Mauduit International, Inc. ("SWM") completed a 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"). On November 30, 2023, the Company completed the sale of the Engineered Papers business ("EP business") to Evergreen Hill Enterprise Pte. Ltd. ("Evergreen Hill Enterprise"). With the sale of the EP business (the "EP Divestiture"), Mativ ceased participating in tobacco-based products markets. The EP business is presented as a discontinued operation for all periods and certain prior period amounts have been retrospectively revised to reflect these changes. The unaudited condensed consolidated financial statements and the notes thereto, unless otherwise indicated, are on a continuing operations basis. Refer to Note 15. Discontinued Operations of the Notes to Condensed Consolidated Financial Statements for more information on the discontinued operations and transaction. Reportable Segments - As part of an organizational realignment effective during the first quarter of 2024, we reorganized into two new reportable segments: (1) Filtration & Advanced Materials ("FAM"), focused primarily on filtration media and components, advanced films, coating and converting solutions, and extruded mesh products, and (2) Sustainable & Adhesive Solutions ("SAS") focused primarily on tapes, labels, liners, specialty paper, packaging and healthcare solutions. The change in reportable segments reflects the realignment of management and the related internal review of our operating segments. The prior period presentation has been revised to align with our current segment reporting structure. 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 ("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, 2024 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, 2023, as filed with the SEC on February 29, 2024. Reclassifications Certain prior year amounts on the unaudited Condensed Consolidated Statements of Income (Loss), unaudited Condensed Consolidated Balance Sheets, unaudited Condensed Consolidated Statements of Cash Flows, and unaudited Notes to Condensed Consolidated Financial Statements have been reclassified to conform to the current year presentation as continuing and discontinued operations and for comparative purposes. Certain prior year amounts in the unaudited Notes to Condensed Consolidated Financial Statements have been reclassified to conform to the current year segments for comparative purposes. Use of Estimates The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the revenues and expenses during the reporting period. Actual results could differ significantly from these estimates. The significant estimates underlying our unaudited condensed consolidated financial statements include, but are not limited to, inventory valuation, goodwill valuation, useful lives of tangible and intangible assets, business acquisitions, equity-based compensation, derivatives, receivables valuation, pension, postretirement and other benefits, taxes and contingencies. Recently Issued Accounting Standards In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." The amendment enhances reportable segment disclosure requirements, primarily regarding significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of other segment items and expanded interim disclosures that align with those required annually, among other provisions. The amendments in this ASU are effective on a retrospective basis for annual periods beginning January 1, 2024, and interim periods within those annual periods beginning January 1, 2025, with early adoption permitted. We do not expect the adoption of ASU 2023-07 to have a significant impact on our financial statement presentation or results. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." The amendment enhances income tax disclosure requirements, particularly regarding the effective tax rate reconciliation and income taxes paid. The amendments in this ASU are effective for fiscal years beginning after December 15, 2024. The Company is in the process of evaluating the effect that the adoption of this standard will have on its consolidated financial statements.
