Nature of Business

Organization and operations - Mativ Holdings, Inc. ("Mativ," "we," "our," or the "Company") 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.

The Engineered Papers business ("EP business"), sold in November 2023 (the "EP Divestiture"), is presented as a discontinued operation where applicable. The unaudited condensed consolidated financial statements and the notes thereto, unless otherwise indicated, are on a continuing operations basis.

Reportable Segments - the Company hastwo 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.

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 months ended March 31, 2025 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, 2024, as filed with the SEC on February 27, 2025.

Reclassifications

Selling expense and General expense prior year amounts in the Condensed Consolidated Statements of Income (Loss) have been reclassified to Selling and general expense and Intangible asset amortization expense to conform to the current year presentation 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 Adopted Accounting Pronouncements

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 became effective on a retrospective basis for annual periods beginning January 1, 2024, and interim periods within those annual periods beginning January 1, 2025. The adoption of this standard is reflected in Note 14. Segment Information.

Recently Issued Accounting Pronouncements

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. We do not expect the adoption of this accounting standard to have an impact on our consolidated financial statements, but this standard will require certain additional disclosures.

In November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures." The ASU requires a public business entity to provide disaggregated disclosures of certain categories of expenses on an annual and interim basis including purchases of inventory, employee compensation, depreciation, and intangible asset amortization for each income statement line item that contains those expenses. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

Note 2. Revenue Recognition

The Company recognizes revenues when control of a product is transferred to the customer. Control is transferred when the products are shipped from one of the Company’s manufacturing facilities to the customer. Any freight costs billed to and paid by a customer are included in Net sales. The cost the Company pays to deliver finished goods to our customers is recorded as a component of Cost of products sold. These costs include the amounts paid to a third party to deliver the finished goods.

Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied, which generally occurs when control of the promised goods or services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Generally, the Company considers collectability of amounts due under a contract to be probable upon inception of a sale based on an evaluation of the credit worthiness of each customer. If collectability is not considered to be probable, the Company defers recognition of revenue on satisfied performance obligations until the uncertainty is resolved. We record estimates for credit losses based on our expectations for the collectability of amounts due from customers, considering historical collections, expectations for future activity and other discrete events as applicable.

Variable consideration, such as discounts or price concessions, is set forth in the terms of the contract at inception and is included in the assessment of the transaction price at the outset of the arrangement. The transaction price is allocated to the individual performance obligations due under the contract based on the relative stand-alone fair value of the performance obligations identified in the contract. The Company typically uses an observable price to determine the stand-alone selling price for separate performance obligations.

The Company does not typically include extended payment terms or significant financing components in its contracts with customers. Certain sales contracts may include cash-based incentives (volume rebates or credits), which are accounted for as variable consideration. We estimate these amounts at least quarterly based on the expected forecast quantities to be provided to customers and adjust revenues recognized accordingly. Incidental items that are immaterial in the context of the contract are recognized as expense in the period incurred. The Company generally expenses sales commissions when incurred because the amortization period is one year or less. These costs are recorded within Selling expense. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less and contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. As a practical expedient, the Company treats shipping and handling activities that occur after control of the good transfers as fulfillment activities, and therefore, does not account for shipping and handling costs as a separate performance obligation.

Net sales are attributed to the following geographic locations of the Company’s direct customers (in millions):

Net sales as a percentage by product category for the business were as follows:

FAM is focused primarily on filtration media and components, advanced films, coating and converting solutions, and extruded mesh products. The FAM segment supplies customers directly, serving a diverse set of generally high-growth end markets.

Filtration & netting – includes high efficiency filtration media and components used in transportation applications, water filtration, industrial processes, life science, HVAC, and air pollution control, as well as extruded mesh products used in agriculture, and various packaging applications.

Advanced films – includes paint protection films used in the transportation aftermarket channel, optical films for glass and glazing applications, interlayer films and lamination for ballistic resistance, medical films and composites for advanced wound care and consumer products, security glass, high-performance graphic substrates, and emerging smart glass applications.

SAS is focused primarily on tapes, labels, liners, specialty paper, packaging and healthcare solutions. The SAS segment supplies customers through distribution and directly, serving growing and mature end markets.

Tapes, labels & liners – includes substrates for tapes used in building & construction, infrastructure, DIY, athletic, and industrial applications, substrates critical to protection and adhesive separation (including release liners and carriers) for applications in the personal care, label, tape, industrial, graphic arts, composites, and medical categories, as well as performance labels, and cable wrapping.

Paper & packaging –includes premium printing and other specialty papers and packaging applications used for print collateral, advertising, direct mail, product packaging, graphics, wallpaper, and education, as well as consumer office, stationery and craft papers sold to large retailers, for small business, personal use and educational applications.

Healthcare & other – includes advanced wound care, consumer wellness, device fixation, medical packaging, as well as a wide range of other solutions and applications.

Transfer of Receivables

On December 23, 2022, and further amended on October 20, 2023, the Company entered into an accounts receivables sales agreement (the "Receivables Sales Agreement") to sell certain trade receivables arising from revenue transactions of the Company's U.S. subsidiaries on a revolving basis. The maximum funding commitment of the Receivables Sales Agreement is $175.0 million. The agreement has an initial term ofthree years and can be renewed.

In connection with the Receivables Sales Agreement, the Company formed a separate bankruptcy-remote special purpose entity ("SPE"), which is a wholly owned and controlled subsidiary. The Company continuously transfers receivables to the SPE and the SPE transfers ownership and control of certain receivables that meet certain qualifying conditions to a third-party financial institution in exchange for cash. Certain receivables are held by the SPE and are pledged to secure the collectability of the sold receivables.

The amount of receivables pledged as collateral as of March 31, 2025 and December 31, 2024 was $28.0 million and $28.7 million, respectively. The SPE incurs fees due to the third-party financial institution related to accounts receivable sales transactions.

The Company has continuing involvement with the receivables transferred by the SPE to the third-party financial institution by providing collection services.

The Company also participates in uncommitted trade accounts receivable sales programs ("Reverse Receivables Programs") under which certain trade receivables are sold, without recourse, to a third-party financial institution in exchange for cash. The Company does not retain any interest in or continuing involvement with the invoices after they are sold. The invoices are sold at face value, less a transaction fee.

The Company accounts for transactions under the Receivables Sales Agreement and Reverse Receivables Programs as sales of financial assets, with the associated receivables derecognized from the Company’s unaudited Condensed Consolidated Balance Sheets. Total fees related to the Receivables Sales Agreement and Reverse Receivables Programs are considered to be a loss on the sale of financial assets. Continuous cash activity related to the Receivables Sales Agreement and Reverse Receivables Programs is reflected in cash from operating activities in the unaudited Condensed Consolidated Statements of Cash Flows.

The following table summarizes the activity under the Receivables Sales Agreement and Reverse Receivables Programs (in millions):

Note 3. Other Comprehensive Loss

Comprehensive loss includes Net loss, as well as items charged directly to stockholders' equity, which are excluded from Net loss. The Company has presented Comprehensive loss in the unaudited Condensed Consolidated Statements of Comprehensive Income (Loss). Reclassification adjustments of derivative instruments from Accumulated other comprehensive income, net of tax are presented in Other income (expense), net or Interest expense in the unaudited Condensed Consolidated Statements of Income (Loss). Refer to Note 10. Derivatives for additional information. Amortization of accumulated pension and other post-employment benefit ("OPEB") liabilities are included in the computation of net pension and OPEB costs, which are discussed in Note 12. Postretirement and Other Benefits.

Components of Accumulated other comprehensive income, net of tax, were as follows (in millions):

Changes in the components of Accumulated other comprehensive income, net of tax, were as follows (in millions):

Note 4. Net Loss Per Share

The Company uses the two-class method to calculate Net loss per share. The Company has granted restricted stock that contains non-forfeitable rights to dividends on unvested shares. Since these unvested shares are considered participating securities under the two-class method, the Company allocates loss per share to common stock and participating securities according to dividends declared and participation rights in undistributed earnings.

Diluted net loss per common share is computed based on Net loss divided by the weighted average number of common and potential common shares outstanding. Potential common shares during the respective periods are those related to dilutive stock-based compensation, including long-term stock-based incentive compensation and directors’ accumulated deferred stock compensation, which may be received by the directors in the form of stock or cash.

A reconciliation of the average number of common and potential common shares outstanding used in the calculations of basic and diluted net loss per share follows (in millions, shares in thousands):

(1)Diluted loss per share excludes an immaterial amount of weighted average potential common shares for the three months ended March 31, 2025 and 2024 as their inclusion would be anti-dilutive.

Note 5. Inventories, Net

Inventories, net are valued at the lower of cost (using the first-in, first-out and weighted average methods) or net realizable value. The Company's costs included in inventory primarily include resins, pulp, chemicals, direct labor, utilities, maintenance, depreciation, finishing supplies and an allocation of certain overhead costs. Machine start-up costs or unplanned machine shutdowns are expensed in the period incurred and are not reflected in inventory. The Company reviews inventories at least quarterly to determine the necessity of write-offs for excess, obsolete or unsalable inventory. The Company estimates write-offs for inventory obsolescence and shrinkage based on its judgment of future realization. These reviews require the Company to assess customer and market demand. There were no material inventory write-offs during the three months ended March 31, 2025 and 2024.

The following table summarizes inventories by major class (in millions):

Note 6. Goodwill

The changes in the carrying amount of goodwill by reportable segment were as follows (in millions):

Accumulated impairment loss for the FAM segment was $411.9 million as of March 31, 2025. Accumulated impairment loss for the SAS segment was $401.0 million as of March 31, 2025.

During the first quarter of 2025, primarily in response to a sustained decline in the Company's share price, an interim quantitative goodwill impairment test was performed.

The fair value of a reporting unit is determined based on an income approach, utilizing estimated future cash flows discounted at a rate commensurate with the risk involved. This approach considers significant assumptions including projections of future performance, specifically our ability to sustain and grow market share at forecasted margins. It also includes significant assumptions around the rate a market participant would use to discount those cash flows. Changes in these assumptions could have a significant impact on the assessment of fair value. The fair value of each reporting unit was ultimately estimated using the income approach; however, management also evaluated fair value under the market approach to ensure the reasonableness of the estimated fair values.

While significant estimates and assumptions related to forecasted future cash flows used in the March 1, 2025, interim impairment test were generally aligned with those used in the annual impairment test performed as of October 1, 2024, the discount rate for the FAM reporting unit which is aligned with the operating and reportable segment, was increased to 14%, to reflect a market participant view of additional risk associated with achieving forecasted cash flows in the growing end markets with which FAM is aligned. The interim impairment test resulted in a full impairment of all goodwill attributable to the FAM reporting unit.

The fair value of the SAS reporting unit, also aligned with the operating and reportable segment, was estimated to exceed its carrying value by approximately 6% as of March 1, 2025. Forecasted cash flows for SAS are primarily aligned with both growing and mature end markets, therefore it is subject to less risk than FAM. The interim impairment test for SAS utilized a discount and long-term growth rates of 10.5% and 2%, respectively.

The Company’s ability to achieve forecasted cash flows in SAS may be negatively impacted by factors including, but not limited to, deterioration of general economic conditions, seasonal or cyclical market and industry fluctuations, adverse changes in our end-market sectors, and the imposition of tariffs and other trade barriers.

Note 7. Intangible Assets

The gross carrying amount and accumulated amortization for intangible assets as of March 31, 2025 consisted of the following (in millions):

The gross carrying amount and accumulated amortization for intangible assets as of December 31, 2024 consisted of the following (in millions):

Amortization expense of intangible assets was $15.4 million and $15.8 million for the three months ended March 31, 2025 and 2024. Intangibles are expensed using the straight-line amortization method.

Note 8. Restructuring and Other Impairment Activities

In January 2024, we announced an organizational realignment initiative (the "Plan") that is expected to streamline organizational size and complexity and leverage business critical resources to enhance customer support and reduce overhead cost. Restructuring and other impairment expenses related to the Plan were comprised primarily of severance charges. Activities associated with the first wave of the Plan were completed during 2024. Charges were $12.7 million for the three months ended March 31, 2024, of which $2.4 million, $7.3 million and $3.0 million incurred within FAM, SAS and Unallocated, respectively.

Restructuring and other impairment expenses in the FAM segment, excluding costs associated with the Plan, were primarily attributable to a facility closure announced in prior years. Through March 31, 2025, the FAM Segment has recognized accumulated restructuring and other impairment charges of $10.7 million related to the facility closure. During the remainder of 2025, the Company expects to record additional restructuring costs in the FAM segment, not expected to exceed $1.5 million related to the closure of this facility.

Restructuring and other impairment expenses in the SAS segment were immaterial.

Assets held for sale of $5.0 million and $10.3 million were included in Other current assets as of March 31, 2025 and 2024, respectively.

The following table summarizes total restructuring and other impairment expense (in millions):

The following table summarizes changes in restructuring liabilities (in millions):

Restructuring liabilities were classified within Accrued expenses and other current liabilities and Other liabilities in the unaudited Condensed Consolidated Balance Sheets.

Note 9. Debt

Total debt, net of debt issuance costs, is summarized in the following table (in millions):

Credit Facility

On September 25, 2018, the Company entered into a $700.0 million credit agreement (the "Credit Agreement"), which replaced the Company’s previous senior secured credit facilities and provides for afive-year $500.0 million revolving line of credit (the "Revolving Credit Facility") and aseven-year $200.0 million bank term loan facility (the "Term Loan A Facility"). Subject to certain conditions, including the absence of a default or event of default under the Credit Agreement, the Company may request incremental loans to be extended under the Revolving Credit Facility or as additional Term Loan Facilities so long as the Company is in pro forma compliance with the financial covenants set forth in the Credit Agreement and the aggregate of such increases does not exceed $400.0 million.

On February 10, 2021, the Company amended its Credit Agreement to, among other things, add a newseven-year $350.0 million Term Loan B Facility (the "Term Loan B Facility") and to decrease the incremental loans that may be extended at the Company’s request to $250.0 million. The amended Credit Agreement was further amended effective February 22, 2022 to adjust the step-down schedule for the maximum net debt to EBITDA ratio.

On May 6, 2022, the Company further amended its Credit Agreement in order to extend the maturity of the Revolving Credit Facility and the Term Loan A Facility to May 6, 2027, and to increase the availability under the Revolving Credit Facility, to $600.0 million. Additionally, the Company added a $650.0 million delayed draw term loan facility (the "Delayed Draw Term Loan Facility"), which the Company borrowed on July 5, 2022, in connection with the Neenah merger. The Delayed Draw Term Loan Facility matures on May 6, 2027.

Borrowings under the amended Term Loan A Facility ("Term Loan A Credit Facility") will bear interest, at a rate equal to either (1) a forward-looking term rate based on the Secured Overnight Financing Rate ("Term SOFR"), plus the applicable margin or (2) the highest of (a) the federal funds effective rate plus 0.5%, (b) the rate of interest as published by the Wall Street Journal as the "bank prime loan" rate, and (c) Term SOFR plus 1.0%, in each case plus the applicable margin. The applicable margin for borrowings under the Term Loan A Credit Facility is expected to range from 1.25% to 3.00% for SOFR loans and from 0.25% to 2.00% for base rate loans, in each case depending on the Company’s then current net debt to EBITDA ratio.

Borrowings under the amended Revolving Facility or the Delayed Draw Term Loan facility in U.S. dollars will bear interest, at the Company’s option, at a rate equal to either (1) a forward-looking term rate based on Term SOFR, plus the applicable margin or (2) the highest of (a) the federal funds effective rate plus 0.5%, (b) the rate of interest as published by the Wall Street Journal as the "bank prime loan" rate, and (c)one-month Term SOFR plus 1.0%, in each case plus the applicable margin. Borrowings under the Revolving Facility in Euros will bear interest at a rate equal to the reserve-adjusted Euro interbank offered rate, or EURIBOR, plus the applicable margin. The applicable margin for borrowings under the revolving credit agreement is expected to range from 1.00% to 2.75% for SOFR loans and EURIBOR loans, and from 0.00% to 1.75% for base rate loans, in each case, depending on the Company’s then current net debt to EBITDA ratio.

Borrowings under the Term Loan B Facility will bear interest, equal to a forward-looking term rate based on Term SOFR (subject to a minimum floor of 0.75%) plus 2.75%. Borrowings under the Term Loan B Facility in Euros will bear interest equal to EURIBOR (subject to a minimum floor of 0% ) plus 3.75%.

Under the terms of the amended Credit Agreement, the Company is required to maintain certain financial ratios and comply with certain financial covenants, including maintaining a net debt to EBITDA ratio, as defined in the amended Credit Agreement, calculated on a trailing four fiscal quarter basis, not greater than 5.50 x and an interest coverage ratio, also as defined in the amended Credit Agreement, of not less than 2.50 x. In addition, borrowings and loans made under the amended Credit Agreement are secured by substantially all of the Company’s and the guarantors’ personal property, excluding certain customary items of collateral, and will be guaranteed by the Company’s existing and future wholly-owned direct material domestic subsidiaries and by Mativ Luxembourg (formerly known as SWM Luxembourg).

The Company was in compliance with all of its covenants under the amended Credit Agreement at March 31, 2025.

Indenture for 8.000% Senior Unsecured Notes Due 2029

On October 7, 2024, the Company closed a private offering of $400.0 million of 8.000% senior unsecured notes due 2029 (the “2029 Notes”). The 2029 Notes were sold in a private placement in reliance on Rule 144A and Regulation S under the Securities Act of 1933, as amended, pursuant to a purchase agreement between the Company, certain subsidiaries of the Company and a third-party financial institution, as representative of the initial purchasers. The 2029 Notes are senior unsecured obligations of the Company and are guaranteed on a senior unsecured basis by each of the Company’s existing and future wholly-owned subsidiaries that is a borrower under or that guarantees obligations under the Company’s senior secured credit facilities or that guarantees certain other indebtedness, subject to certain exceptions.

The 2029 Notes were issued pursuant to an Indenture (the “Indenture”), dated as of October 7, 2024, among the Company, the guarantors listed therein and a third-party financial institution, as trustee. The Indenture provides that interest on the 2029 Notes will accrue from October 7, 2024 and is payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2025, and the 2029 Notes mature on October 1, 2029, subject to earlier repurchase or redemption.

The Company may redeem some or all of the 2029 Notes at any time on or after October 1, 2026, at the redemption prices set forth in the Indenture, together with accrued and unpaid interest, if any, to, but excluding, the redemption date. If the Company sells certain assets or consummates certain change of control transactions, the Company will be required to make an offer to repurchase the 2029 Notes, subject to certain conditions.

The Indenture contains certain covenants that, among other things, limit the Company’s ability and the ability of its restricted subsidiaries to incur additional indebtedness, make certain dividends, repurchase Company stock or make other distributions, make certain investments, create liens, transfer or sell assets, merge or consolidate and enter into transactions with the Company’s affiliates. Such covenants are subject to a number of exceptions and qualifications set forth in the Indenture. The Indenture also contains certain customary events of default, including failure to make payments in respect of the principal amount of the 2029 Notes, failure to make payments of interest on the 2029 Notes when due and payable, failure to comply with certain covenants and agreements and certain events of bankruptcy or insolvency. The Company was in compliance with all of its covenants under the Indenture at March 31, 2025.

As of March 31, 2025, the average interest rate was 7.00% on outstanding Revolving Facility borrowings,7.17% on outstanding Term Loan A Credit Facility borrowings,8.19% on outstanding Term Loan B Facility borrowings, and 6.92% on outstanding Delayed Draw Term Loan Facility borrowings. The effective rate on the Notes was 8.000%. The weighted average effective interest rate on the Company's debt facilities, including the impact of interest rate hedges, was approximately 7.44% and 5.94% for the three months ended March 31, 2025 and 2024, respectively.

Principal Repayments

The following is the expected maturities for the Company's debt obligations, net of fair value adjustments associated with interest rate swaps, as of March 31, 2025 (in millions):

Fair Value of Debt

At March 31, 2025 and December 31, 2024, the fair market value of the 2029 Notes was $345.0 million and $383.5 million, respectively. The fair market value for the Notes was determined using quoted market prices, which are directly observable Level 1 inputs. The fair market value of all other debt as of March 31, 2025 and December 31, 2024 approximated the respective carrying amounts as the interest rates approximate current market indices.

Note 10. Derivatives

In the normal course of business, the Company is exposed to foreign currency exchange rate risk and interest rate risk on its variable-rate debt. To manage these risks, the Company utilizes a variety of practices including derivative instruments. The Company has no derivative instruments for trading or speculative purposes or derivatives with credit risk-related contingent features. All derivative instruments used by the Company are either exchange traded or are entered into with major financial institutions to reduce credit risk and risk of nonperformance by third parties. The fair values of the Company’s derivative instruments are determined using observable inputs and are considered Level 2 assets or liabilities.

Foreign Currency Risk Management

The Company utilizes currency forward, swap and, to a lesser extent, option contracts to selectively hedge its exposure to foreign currency risk when it is practical and economical to do so. The use of these contracts minimizes transactional exposure to exchange rate changes. We designate certain of our foreign currency hedges as cash flow hedges. Changes in the fair value of cash flow hedges are reported as a component of Accumulated other comprehensive loss, net of tax and reclassified into earnings when the forecasted transaction affects earnings. Changes in the fair value of foreign exchange contracts not designated as hedges are recorded to Net income (loss) each period.

The Company also uses cross-currency swap contracts to selectively hedge its exposure to foreign currency related changes in our net investments in certain foreign operations. We designate these cross-currency swap contracts as net investment hedges based on the spot rate of the EUR. Changes in the fair value of these hedges are deferred within the foreign currency translation component of Accumulated other comprehensive loss, net of tax and reclassified into earnings when the foreign investment is sold or substantially liquidated. Future changes in the components related to the spot change on the notional will be recorded in Other Comprehensive Income ("OCI") and remain there until the hedged subsidiaries are substantially liquidated. Gains and losses excluded from the assessment of hedge effectiveness are recognized in earnings (Interest expense) over the term of the swap. Gains and losses associated with the settlement of derivative instruments designated as a net investment hedge are classified within investing activities in the Consolidated Statement of Cash Flows. As of March 31, 2025 and December 31, 2024 the gross notional amount of outstanding cross-currency swaps contracts designated as a net investment hedge was €450 million.

Interest Rate Risk Management

The Company selectively hedges its exposure to interest rate increases on variable-rate, long-term debt when it is practical and economical to do so. Changes in the fair value of pay-fixed, receive-variable interest rate swap contracts considered cash flow hedges are reported as a component of Accumulated other comprehensive loss, net of tax and reclassified into earnings when the forecasted transaction affects earnings. The terms of the interest rate swaps mirror the terms of the underlying debt, including timing of the payments and interest rates. As of March 31, 2025 and December 31, 2024 the gross notional amounts of outstanding interest rate swaps designated as a cash flow hedge were $589.2 million and $589.2 million, respectively.

The following table presents the fair value of asset and liability derivatives and the respective balance sheet locations at March 31, 2025 (in millions):

The following table presents the fair value of asset and liability derivatives and the respective balance sheet locations at December 31, 2024 (in millions):

Gains (losses) on derivatives designated as cash flow and net investment hedges recognized in other comprehensive loss are summarized below (in millions) on a pretax basis:

The Company's designated derivative instruments are highly effective. As such, there were no gains or losses recognized immediately in income related to the hedge ineffectiveness or amounts excluded from hedge effectiveness testing for the three months ended March 31, 2025 or 2024, other than those related to derivatives designated as a net investment hedge, noted below.

Gains (losses) on derivatives within the Condensed Consolidated Statement of Income (Loss) were as follows (in millions):

Deferred gains of $8.2 million attributable to settled interest rate swaps designated as cash flow hedges are expected to be reclassified to Interest expense over the next twelve months.

Note 11. Commitments and Contingencies

Other Commitments

In connection with the EP Divestiture, we undertook to indemnify and hold Evergreen Hill Enterprise harmless from claims and liabilities related to the EP business that were identified as excluded or specified liabilities in the related agreements up to an amount not to exceed $10 million. As of March 31, 2025, there were no material claims pending under this indemnification.

Litigation

We are involved in various legal proceedings from time to time, including relating to contracts, commercial disputes, taxes, environmental issues, employment and workers' compensation claims, product liability and other matters. We periodically review the status of these proceedings with both inside and outside counsel. We believe that the ultimate disposition of these matters will not have a material effect on the results of operations in a given quarter or year.

Environmental Matters

The Company's operations are subject to various nations' federal, state and local laws, regulations and ordinances relating to environmental matters. The nature of the Company's operations exposes it to the risk of claims with respect to various environmental matters, and there can be no assurance that material costs or liabilities will not be incurred in connection with such claims. While the Company has incurred in the past several years, and will continue to incur, capital and operating expenditures in order to comply with environmental laws and regulations, it believes that its future cost of compliance with environmental laws, regulations and ordinances, and its exposure to liability for environmental claims and its obligation to participate in the remediation and monitoring of certain hazardous waste disposal sites, will not have a material effect on its financial condition or results of operations. However, future events, such as changes in existing laws and regulations, or unknown contamination or costs of remediation of sites owned, operated or used for waste disposal by the Company (including contamination caused by prior owners and operators of such sites or other waste generators) may give rise to additional costs which could have a material effect on its financial condition or results of operations.

Employees and Labor Relations

As of March 31, 2025, approximately 26% of the Company's U.S. workforce and 36% of its Non-U.S. workforce are under collective bargaining agreements. Approximately 19% of all U.S. employees and 18% of Non-U.S. employees are under collective bargaining agreements that will expire in the next 12 months.

For the Non-U.S. workforce, union membership is voluntary and does not need to be disclosed to the Company under local laws. As a result, the number of employees covered by the collective bargaining agreements in some countries cannot be determined.

General Matters

In the ordinary course of conducting business activities, the Company and its subsidiaries become involved in certain other judicial, administrative and regulatory proceedings involving both private parties and governmental authorities. These proceedings include insured and uninsured regulatory, employment, intellectual property, general and commercial liability, environmental and other matters. At this time, the Company does not expect any of these proceedings to have a material effect on its reputation, business, financial condition, results of operations or cash flows. However, the Company can give no assurance that the results of any such proceedings will not materially affect its reputation, business, financial condition, results of operations or cash flows.

Note 12. Postretirement and Other Benefits

The Company sponsors a number of different defined contribution retirement plans, alternative retirement plans and/or defined benefit pension plans across its operations. Defined benefit pension plans are sponsored in the United States, France, United Kingdom, Germany, Italy, and Canada and OPEB benefits related to post-retirement healthcare and life insurance are sponsored in the United States, Germany, and Canada. As of March 31, 2025, retained contributions associated with our UK Pension scheme with the use restricted to obligations related to the scheme are included in the Restricted cash of $9.8 million.

The components of net pension cost (benefit) during the three months ended March 31, 2025 and 2024 were as follows (in millions):

The components of net pension cost (benefit) other than the service cost component are included in Other income (expense), net in the unaudited Condensed Consolidated Statements of Loss.

The Company's cost under the qualified defined contribution retirement plans was $3.8 million and $3.5 million, respectively, for the three months ended March 31, 2025 and 2024.

Note 13. Income Taxes

The Company's effective tax rate from continuing operations was 5.5% and 7.9% for the three months ended March 31, 2025 and 2024, respectively. The net change was primarily due to mix of earnings, impact from a $48.2 million increase to our valuation allowance, and goodwill impairment not deductible for tax purposes in the current period. The Company has historically calculated the provision or benefit for income taxes during interim reporting periods, by applying an estimate of the annual effective tax rate for the full fiscal year to “ordinary” income or loss (pre-tax income or loss excluding unusual or infrequently occurring discrete items) for the reporting period. The Company determined that since small changes in estimated “ordinary” income would result in significant changes in the estimated annual effective tax rate, the historical method would not provide a reliable estimate for the three-month period ended March 31, 2025. Accordingly, Mativ used a discrete effective tax rate method to calculate taxes for the three-month period ended March 31, 2025.

Prior to the passage of the Tax Cuts and Jobs Act of 2017 ("Tax Act"), the Company asserted that substantially all of the undistributed earnings of its foreign subsidiaries were considered indefinitely reinvested and accordingly, no deferred taxes were provided. Due to the Tax Act, the Company has significant previously taxed earnings and profits from its foreign subsidiaries, as a result of transition tax, that it is generally able to be repatriated free of U.S. federal tax. In addition, future earnings of foreign subsidiaries are generally expected to be able to be repatriated free of U.S. federal income tax because these earnings were taxed in the U.S. under the GILTI regime or would be eligible for a 100% dividends received deduction. As a result of the Company’s treasury policy to simplify and expediate its intercompany cash flows, as evidenced by the use of cash pooling, and in light of the Company’s demonstrated goal of driving growth though inorganic/acquisitional means, the Company does not assert indefinite reinvestment to the extent of each controlled foreign corporation's earnings and profits and to the extent of any foreign partnership’s U.S. tax capital accounts. As a result, the Company has provided for non-U.S. withholding taxes, U.S. federal tax related to currency movement on previously taxed earnings and profits, and U.S. state taxes on unremitted earnings.

All unrecognized tax positions could impact the Company's effective tax rate if recognized. There have been no material changes to the Company’s unrecognized tax positions for the three months ended March 31, 2025. With respect to penalties and interest incurred from income tax assessments or related to unrecognized tax benefits, the Company’s policy is to classify penalties as provision for income taxes and interest as interest expense in its unaudited Condensed Consolidated Statements of Income (Loss). There wereno material income tax penalties or interest accrued during the three months ended March 31, 2025 or 2024.

Many jurisdictions in which the Company operates have implemented Pillar Two legislation, and others are considering implementation of Pillar Two rules. While such new rules introduce complexity into the Company’s calculation of income tax expense, Pillar Two does not have a material impact as of the first quarter of 2025. Due to the novelty and complexity of Pillar Two, the Company continues to monitor for advancements and further guidance in Pillar Two rules, considering impacts of such developments on its tax expense.

General corporate expenses that do not directly support the operations of the business segments are unallocated expenses. Assets are managed on a total company basis and are therefore not disclosed at the segment level.

Net sales, costs of products sold, nonmanufacturing expense, restructuring and impairment expense, and operating profit (loss) by segments were (in millions):
