Item 8.01. Other Events.

As previously disclosed, on August 5, 2025, MasterBrand, Inc., a Delaware corporation (the “Company” or “MasterBrand”), entered into an Agreement and Plan of Merger (the “Merger Agreement,” and the transactions contemplated thereby, the “Merger”) with American Woodmark Corporation, a Virginia corporation (“American Woodmark”), and Maple Merger Sub, Inc., a Virginia Corporation and a wholly owned subsidiary of the Company.

On October 3, 2025, MasterBrand received notice from the Federal Competition Commission of Mexico that it approved the Merger, in satisfaction of one of the regulatory approvals required to be obtained as a condition to the Merger.

In addition, as agreed by the parties, on October 6, 2025, MasterBrand, as the acquiring party, voluntarily withdrew its pre-merger Notification and Report Form filed pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), in order to provide the Federal Trade Commission (the “FTC”) with additional time to review the Merger.

In accordance with the regulations under the HSR Act, MasterBrand plans to resubmit its HSR Act Notification and Report Form by October 8, 2025, commencing a new 30-day waiting period under the HSR Act. Withdrawing and refiling pre-merger notifications is a standard procedure in order to provide additional time for antitrust review of certain transactions. The Company and American Woodmark continue to work constructively with FTC staff in the FTC’s review of the Merger and continue to expect to consummate the Merger in early 2026. In addition to the receipt of clearance of the Merger under the HSR Act, the Merger remains subject to the adoption by American Woodmark’s shareholders of the Merger Agreement and the related plan of merger, the approval by MasterBrand stockholders of the issuance of MasterBrand common stock to American Woodmark shareholders pursuant to the Merger Agreement, and the satisfaction or waiver of other customary closing conditions.

Cautionary Note Regarding Forward-Looking Statements

Certain statements contained in this Current Report on Form 8-K, other than purely historical information, including, but not limited to, statements as to the likelihood and anticipated timing of the closing of the proposed transaction, expected cost synergies and other expected benefits, effects or outcomes relating to the proposed transaction, including financial estimates and projections, MasterBrand’s business plans, objectives and expected operating results, and the assumptions upon which those statements are based, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Statements preceded by, followed by or that otherwise include the word “believes,” “expects,” “anticipates,” “intends,” “projects,” “estimates,” “plans,” “may increase,” “may fluctuate,” and similar expressions or future or conditional verbs such as “will,” “should,” “would,” “may,” and “could,” are generally forward-looking in nature and not historical facts. Where, in any forward-looking statement, an expectation or belief is expressed as to future results or events, such expectation or belief is based on the current plans and expectations of the management of MasterBrand or American Woodmark, as applicable. Although MasterBrand and American Woodmark, as applicable, believe that these statements are based on reasonable assumptions, they are subject to numerous factors, risks and uncertainties that could cause actual outcomes and results to be materially different from those indicated or implied in such statements. These factors include a failure by either party or both parties to satisfy one or more of the closing conditions set forth in the merger agreement, including a failure to obtain any required regulatory or governmental approvals or a failure to obtain the required approvals of either American Woodmark’s shareholders or MasterBrand’s stockholders; the occurrence of events or changes in circumstances that give rise to the termination of the merger agreement by either party or a delay in the closing of the transaction; potential litigation relating to the transaction; the effect of the proposed transaction on the ability of either party to retain customers, maintain relationships with suppliers and hire and retain key personnel; the effect of the proposed transaction and the announcement of the proposed transaction on the parties’ stock prices; disruptions in the ordinary course business of either party resulting from the transaction; the continued availability of capital and financing and any rating agency actions related to the transaction or otherwise; the risk that certain limitations in the merger agreement may impact either party’s ability to pursue certain business opportunities or strategic transactions; the diversion of the attention and time of management of either party from ordinary course business operations to the transaction and transaction-related issues; the impact of transaction and/or integration costs and any increases in such costs; the existence of unknown liabilities; the ability of MasterBrand to successfully integrate American Woodmark into its business and operations; and the risk that any anticipated economic benefits, cost savings or other synergies are not fully realized or take longer to realize than expected. Other factors include those listed under “Risk Factors” in Part I, Item 1A of MasterBrand’s Annual Report on Form 10-K for the fiscal year ended December 29, 2024, Part II, Item 1A of MasterBrand’s Quarterly Report on Form 10-Q for the quarterly period ended March 30, 2025, Part II, Item 1A of MasterBrand’s Quarterly Report on Form 10-Q for the quarterly period ended June 29, 2025, Part I, Item 1A of American Woodmark’s Annual Report on Form 10-K for the fiscal year ended April 30, 2025, Part II, Item 1A of American Woodmark’s Quarterly Report on Form 10-Q for the quarterly period ended July 31, 2025, and other MasterBrand and American Woodmark filings with the SEC.

The forward-looking statements included in this Current Report on Form 8-K are made as of the date of this Current Report on Form 8-K and, unless legally required, neither MasterBrand nor American Woodmark undertakes any obligation to update, amend or clarify any forward-looking statements to reflect events, new information or circumstances occurring after the date of this Current Report on Form 8-K.
