The quarters ended March 31, 2022 and June 30, 2022 included in Exhibit 99.2 also reflect the adjustments for the Neenah Merger previously reported on the December 22, 2022 Current Report on Form 8-K.

EXHIBIT 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Introduction

As previously disclosed on a Current Report on Form 8-K, on August 1, 2023, Mativ Holdings, Inc. (the “Company”) entered into a final, binding and irrevocable offer letter (the “Offer Letter”) with Evergreen Hill Enterprise Pte. Ltd., an affiliate of PT Bukit Muria Jaya (“Buyer”) pursuant to which Buyer made a binding offer (the “Offer”) to acquire the Company’s Engineered Papers business (the “Transaction”). The Company accepted Buyer’s Offer and countersigned the Purchase Agreement, dated as of August 1, 2023 (the “Purchase Agreement”), with respect to the EP Divestiture on October 4, 2023. On November 30, 2023, and pursuant to the Purchase Agreement, the Buyer acquired the Company’s Engineered Papers business. The gross purchase price was $620.0 million in cash, subject to certain customary adjustments as set forth in the Purchase Agreement.

The unaudited pro forma condensed consolidated balance sheet as of September 30, 2023, presents the Company’s consolidated financial position giving pro forma effect to the Transaction as if it had occurred on September 30, 2023. The following unaudited pro forma condensed consolidated statement of income (loss) for the nine months ended September 30, 2023, and consolidated statements of income (loss) for the years ended December 31, 2022, 2021, and 2020 present the Company’s consolidated results of operations giving pro forma effect to the Transaction as if it had occurred on January 1, 2020.

The unaudited pro forma condensed consolidated financial statements presented below have been derived from the Company’s historical consolidated financial statements. While the historical consolidated financial statements reflect the past financial results of the Company, the pro forma condensed consolidated financial statements are included for informational purposes only and are intended to illustrate how the Transaction might have affected the historical consolidated financial statements had it been completed at an earlier time as indicated herein. The Transaction constituted a significant disposition for purposes of Item 2.01 of Form 8-K and these unaudited pro forma condensed consolidated financial statements have been prepared in accordance with Article 11 of Regulation S-X, Pro Forma Financial Information, and include adjustments to the extent that they are directly attributable to the Transaction. The following unaudited pro forma condensed consolidated financial statements give rise to the following transactions:

The elimination of the net assets and financial performance of the Company’s Engineered Papers business in<br>accordance with rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”).
The Company’s use of net sale proceeds to make a debt repayment in accordance with the Company’s credit<br>agreement.
--- ---

These pro forma adjustments are based on currently available information, estimates and assumptions that the Company believes are reasonable in order to reflect, on a pro forma basis, the impact of the Transaction on the Company’s historical information, and are not necessarily indicative of the Company’s future financial position and future results of operations and do not reflect all actions that may be taken by the Company following the closing of the Transaction. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors.

The unaudited pro forma condensed consolidated financial statements do not reflect the realization of any expected cost savings, synergies or dis-synergies as a result of the Transaction. We considered the impact of the Transition Services Agreement and determined that no further pro forma adjustments were necessary as we do not believe presenting such adjustments would enhance an understanding of the pro forma effects of the Transaction as the agreement is not expected to have a material impact on the unaudited pro forma condensed consolidated balance sheet as of September 30, 2023 or the unaudited pro forma condensed consolidated statements of income (loss) for the nine months ended September 30, 2023 and the years ended December 31, 2022, 2021, and 2020.

These unaudited pro forma condensed consolidated financial statements should be read in connection with:

the Company’s historical audited consolidated financial statements, the accompanying notes and<br>“Managements Discussion of Analysis of Financial Condition and Results of Operations” included in the Company’s Annual Reports on Form 10-K for the years ended December 31, 2022, 2021, and<br>2020 filed with the SEC on March 1, 2023, March 1, 2022, and March 1, 2021, respectively;
the Company’s unaudited interim historical consolidated financial statements, the accompanying notes and<br>“Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in the Company’s Quarterly Report on Form 10-Q for the three and nine months ended<br>September 30, 2023, filed with the SEC on November 9, 2023; and

(1) Represents the Company’s unaudited condensed consolidated balance sheet as contained in the Quarterly<br>Report on Form 10-Q for the nine months ended September 30, 2023, filed with the SEC on November 9, 2023.
(2) These adjustments reflect the estimated cash proceeds of $669.4 million from the Transaction, as adjusted<br>per the terms of the Purchase Agreement for estimated levels of cash, debt-like items, transaction costs and net working capital, and the elimination of the assets and liabilities attributable to the Engineered Papers business in accordance with ASC<br>205, less estimated transaction costs of $23.2 million (primarily legal and other advisor fees) that are directly attributable to the Transaction. In addition, approximately $5.0 million income tax payable associated with the gain on sale.<br>
--- ---
(3) This adjustment reflects the estimated pro forma gain on disposal, which is calculated as the difference<br>between estimated net cash proceeds from the Transaction (refer to adjustment (2) above) and the historical carrying value of the Engineered Papers business disposal group as of September 30, 2023, net of estimated income taxes. The actual<br>gain on disposal, and the Company’s estimate of income taxes, will be based on the balance sheet information as of the Closing and the finalization of the Company’s current fiscal year tax provision, and may differ significantly. The pro<br>forma gain on disposal has not been reflected in the unaudited pro forma condensed consolidated statements of operations as this amount pertains to discontinued operations and does not impact income from continuing operations.
--- ---
(4) This adjustment reflects the release of the unrealized foreign currency translation adjustments into earnings<br>for disposed foreign entities.
--- ---
(5) These adjustments reflect the Company’s debt repayment of $641.2 million, in accordance with the<br>Company’s credit agreement.

EX-99.2

Exhibit 99.2

As previously disclosed on a Current Report on Form 8-K, on August 1, 2023, Mativ Holdings, Inc. (the “Company”) entered into a final, binding and irrevocable offer letter (the “Offer Letter”) with Evergreen Hill Enterprise Pte. Ltd., an affiliate of PT Bukit Muria Jaya (“Buyer”) pursuant to which Buyer made a binding offer (the “Offer”) to acquire the Company’s Engineered Papers business (the “EP Divestiture”). The Company accepted Buyer’s Offer and countersigned the Purchase Agreement, dated as of August 1, 2023 (the “Purchase Agreement”), with respect to the EP Divestiture on October 4, 2023. On November 30, 2023 and pursuant to the Purchase Agreement, the Buyer acquired the Company’s Engineered Papers business. The gross purchase price was $620 million in cash, subject to certain customary adjustments as set forth in the Purchase Agreement.

Supplemental Comparable FinancialInformation

Due to the significance of the EP Divestiture which is accounted for as discontinued operations, the Company is providing the supplemental financial information set forth in the attached schedules to enhance its shareholders’ ability to evaluate the Company’s performance from continuing operations on a comparable basis. The purpose of the supplemental financial information provided in the attached schedules is to reflect the impact of the EP Divestiture as discontinued operations and to present certain non-GAAP financial measures quarterly on a comparable basis beginning with the first quarter of 2022. The Company previously filed a Current Report on Form 8-K on December 22, 2022 to provide supplemental combined legacy financial information to reflect the changes to the Company’s reportable segments following the closing of the merger with Neenah, Inc. (“Neenah”). The quarters ended March 31, 2022 and June 30, 2022 included in the attached schedules also reflect the adjustments for the Neenah merger previously reported on the December 22, 2022 Current Report on Form 8-K.

The supplemental financial information in the attached schedules is not necessarily indicative of the operating results of the Company had the EP Divestiture and the Neenah merger been completed at the beginning of or prior to the periods presented or of the operating results of the Company in the future. The supplemental financial information is not pro forma information prepared in accordance with Article 11 of Regulation S-X of the SEC, and the preparation of information in accordance with Article 11 would result in a different presentation. Pro forma financial information prepared pursuant to Article 11, including unaudited pro forma condensed consolidated statements of operations for the Company for the nine months ended September 30, 2023, as well as the years ended December 31, 2022, 2021, and 2020, and an unaudited pro forma condensed consolidated balance sheet as of September 30, 2023, in each case giving effect to the EP Divestiture, is attached as Exhibit 99.1 to the Company’s Current Report on Form 8-K/A filed on December 6, 2023.

Non-GAAP Financial Measures

Certain financial measures and comments contained herein exclude restructuring, impairment and other expenses, certain purchase accounting adjustments related to the Advanced Technical Materials and Fiber-Based Solutions segment acquisitions, acquisition/merger and integration related costs, stock-based compensation, and depreciation and amortization. Financial measures which exclude or include these items have not been determined in accordance with accounting principles generally accepted in the United States (“GAAP”) and are therefore “non-GAAP” financial measures. Reconciliations of these non-GAAP financial measures to the most closely analogous measure determined in accordance with GAAP for the quarters ended March 31, 2022 and June 30, 2022, are included in the financial schedules attached hereto.

The Company believes the presentation of non-GAAP financial measures in addition to the related GAAP measures provides investors with greater transparency on the information used by the Company’s management in its financial and operational decision-making. Management also believes the non-GAAP financial measures provide additional insight for analysts and investors in evaluating the Company’s financial and operational performance in the same way that management evaluates the Company’s financial performance. Management believes providing this information enables investors to better understand the Company’s operating performance and financial condition. These non-GAAP financial measures are not calculated or presented in accordance with, and are not intended to be considered in isolation or as alternatives or substitutes for, or superior to, financial measures prepared and presented in accordance with GAAP, and should be read only in conjunction with the Company’s financial measures prepared and presented in accordance with GAAP. The non-GAAP financial measures used in this release may be different from the measures used by other companies.
