Insights

M&A valuation analyst

Supplemental proxy data outlines projections and valuation anchors; neutral impact.

The filing adds quantitative inputs that advisors used to evaluate the merger, including stand‑alone projections, trading comps, precedent deals, and DCF assumptions. These items frame how value was assessed without changing stated transaction mechanics.

Key anchors include EV/EBITDA ranges for peers, projected revenue and Adjusted EBITDA profiles through 2029, and DCF settings of 2.0%–2.5% perpetuity growth with 9.5%–10.5% discount rates. Such disclosures help compare each company’s earnings power against sector benchmarks.

The practical effect depends on how stakeholders weigh these metrics in their vote decisions; the filing itself lists methods and figures but does not alter terms. Subsequent company materials may provide additional context around these projections and analyses.

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”) with American Woodmark Corporation, a Virginia corporation (“American Woodmark”), and Maple Merger Sub, Inc., a Virginia Corporation and a wholly owned subsidiary of MasterBrand (“Merger Sub”). The Merger Agreement provides for, among other things and subject to the satisfaction or waiver of specified conditions set forth therein, the merger of Merger Sub with and into American Woodmark with American Woodmark surviving as a wholly owned subsidiary of MasterBrand (the “Merger”). On September 5, 2025, MasterBrand filed with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-4 (File No. 333-290071) (the “Registration Statement”), containing a joint proxy statement of MasterBrand and American Woodmark that also constitutes a prospectus of MasterBrand (the “Joint Proxy Statement/Prospectus”). MasterBrand subsequently filed with the SEC an amended Registration Statement on Form S-4/A on September 23, 2025, and the Registration Statement as amended was declared effective by the SEC on September 25, 2025. Following the effectiveness of the Registration Statement, MasterBrand and American Woodmark commenced mailing the Joint Proxy Statement/Prospectus to their respective stockholders on September 25, 2025.

Certain Litigation

Since the filing of the Registration Statement, the Company and American Woodmark have received several demand letters from counsel representing purported stockholders of the Company and/or American Woodmark, as applicable, alleging, among other things, that the Joint Proxy Statement/Prospectus filed in connection with the Merger omitted certain purportedly material information which rendered such document incomplete and misleading. In addition, following the filing of the Joint Proxy Statement/Prospectus, a lawsuit was filed by a purported stockholder of the Company in connection with the Merger under the caption Dean Drulias v. R. David Banyard, Jr., et al. No. 25-125754 (OH) and lawsuits were filed by a purported stockholder of American Woodmark in connection with the Merger under the captions Matthew Hamilton v. American Woodmark, et al., No. 656018/2025 (NY) and Eric Muller v. American Woodmark, et al., No. 656014/2025 (NY) (collectively, the “Complaints”). The Complaints similarly allege that the Joint Proxy Statement/Prospectus filed in connection with the Merger omitted certain purportedly material information which rendered the Joint Proxy Statement/Prospectus incomplete and misleading.

While the Company, American Woodmark and the other defendants named in the matters, as applicable, believe that the disclosures set forth in the Joint Proxy Statement/Prospectus comply fully with all applicable laws and deny the allegations in the demand letters and the Complaints, in order to moot the plaintiffs’ disclosure claims and avoid nuisance and possible expense and business delays, the Company and American Woodmark have determined to voluntarily supplement certain disclosures in the Joint Proxy Statement/Prospectus related to the plaintiff’s claims with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal merit, necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, the Company and American Woodmark specifically deny all allegations that any additional disclosure was or is required or material.

SUPPLEMENTAL DISCLOSURES

This supplemental information should be read in conjunction with the Joint Proxy Statement/Prospectus, which should be read in its entirety, including the cautionary notes regarding the risks and limitations associated with relying on prospective financial information. The inclusion in this supplement to the Joint Proxy Statement/Prospectus of certain summary unaudited prospective financial information should not be regarded as an indication that any of the Company, American Woodmark or their respective affiliates, officers, directors or other representatives, or any other recipient of this information, considered, or now considers, it to be material or to be necessarily predictive of actual future results, and the unaudited prospective financial information should not be relied upon as such. To the extent defined terms are used but not defined herein, they have the meanings set forth in the Joint Proxy Statement/Prospectus. For clarity, new text within restated paragraphs from the Joint Proxy Statement/Prospectus is highlighted with bold, underlined text, and deleted text within restated paragraphs from the Joint Proxy Statement/Prospectus is highlighted with strikethrough text.

Amending and restating in its entirety the below paragraph on page 79 of the Joint Proxy Statement/Prospectus in the section entitled “The Merger–Background of the Merger” as follows:

On April 8, 2025, Mr. Banyard and Mr. Culbreth met in person in Paris, Virginia to discuss further the potential business combination and next steps. During the conversation, Mr. Banyard shared his thoughts regarding why timing of the potential business combination made sense particularly during a down market, including that each company would be better placed to withstand challenging macroeconomic conditions together, as opposed to independently, and that the companies’ share prices moved largely in-line with each other over time, regardless of stronger or weaker market conditions. Mr. Banyard also discussed MasterBrand’s experience with integration and synergies achievement in connection with MasterBrand’s recent purchase of Supreme, his thoughts on certain benefits of the potential business combination to shareholders, customers and consumers and his proposal to select a small group of advisors and build a “clean team virtual data room” for each company to complete a review of the potential value creation from a potential business combination before taking further substantive steps. Mr. Culbreth also indicated to Mr. Banyard that further support was still needed from the American Woodmark board of directors before taking further substantive steps. It was agreed that Mr. Culbreth would discuss potential next steps with his management team, the American Woodmark board of directors and outside legal and financial advisors. After the meeting, Mr. Culbreth informed the remaining American Woodmark management team regarding the discussions with Mr. Banyard.

On July 23, 2025, Mr. Banyard and Mr. Culbreth had a video meeting in which they discussed the number of directors from American Woodmark that would join the board of the combined company, American Woodmark’s proposal to receive a reverse termination fee, American Woodmark’s executive team, conversion of outstanding American Woodmark equity awards in connection with the potential business combination, communications resources, due diligence and synergies assessment progress, and employee retention considerations. Mr. Culbreth provided Mr. Banyard with additional information about the special retention awards made by American Woodmark to certain members of management on July 3, 2025, in connection with seeking to ensure executive management retention following Mr. Joachimczyk’s departure, due to the challenging business environment and increased economic uncertainty, and to further focus executive management on long-term value creation by further aligning their interests with those of American Woodmark’s shareholders. Mr. Culbreth noted that these special retention awards had previously been considered by the Compensation Committee of the American Woodmark board of directors over the past few months.

Unlevered free cash flow(3)		$	34.7			$	90.7			$	90.7			$	116.4			$	142.2

(1)(2) Adjusted EBITDA is calculated as GAAP net income before depreciation and amortization, interest expense, income taxes, and other non-cash or special items, including restructuring and restructuring-related charges, asset impairments, debt issuance and refinancing costs, acquisition-related costs and integration expenses.

(2)(3) Unlevered free cash flow is a non-GAAP measure calculated as Adjusted EBITDA, less cash taxes, non-cash equity-based compensation costs, capital expenditures and changes in net working capital. The number presented for unlevered free cash flow in the column labeled CY25E reflects unlevered free cash flow for the second half of 2025.

Selected Public Companies Trading Analysis

Rothschild & Co considered certain financial data for MasterBrand, American Woodmark and selected companies with publicly traded equity securities Rothschild & Co deemed relevant. Rothschild & Co used the same selected companies in its selected companies analysis for each of MasterBrand and American Woodmark. The selected companies were selected because they were deemed to be similar to MasterBrand and American Woodmark in one or more respects. As noted above, the selected companies used in the selected companies analysis for comparative purposes to MasterBrand and American Woodmark, other than MasterBrand and American Woodmark, respectively, are not identical to MasterBrand or American Woodmark, and an evaluation of the results of the selected companies analysis is not entirely mathematical. As a consequence, the ranges of multiples applied for purposes of the selected companies analysis were selected based on Rothschild & Co’s experience and judgment. Unless the context indicates otherwise, share prices for the selected companies used in the selected companies analysis described below were closing prices as of August 1, 2025. Estimates of future financial performance for the years ending December 31, 2025 and 2026 for the selected companies listed below, including MasterBrand and American Woodmark, were based on publicly available research analyst estimates for those companies.

The financial data reviewed included:

• Enterprise Value as a multiple of estimated Adjusted EBITDA for the year ended December 31, 2025, or “2025E EBITDA”;

6

• Enterprise Value as a multiple of estimated Adjusted EBITDA for the year ended December 31, 2026, or “2026E EBITDA”;

These selected companies (and corresponding multiples) used by Rothschild & Co in its analyses were:

Selected Precedent Transactions Analysis

Rothschild & Co considered the financial terms of certain business combinations and other transactions that had previously been announced and which Rothschild & Co deemed relevant. Rothschild & Co used the same transactions in its selected transactions analysis of each of MasterBrand and American Woodmark. The selected transactions were selected because the target companies were deemed similar to MasterBrand and American Woodmark in one or more respects. As noted above, none of the selected transactions used for comparative purposes is identical to a transaction involving MasterBrand or American Woodmark on the date of the announcement of the merger, and an evaluation of the results of the selected transactions analysis is not entirely mathematical. As a consequence, the ranges of multiples applied for purposes of the selected transactions analysis were selected based on Rothschild & Co’s experience and judgment. Financial data for the selected transactions were based on public filings, publicly available research analyst estimates and other publicly available information.

The financial data reviewed for the selected transactions analyses included Enterprise Value implied by the consideration proposed or paid in the selected transactions as a multiple of estimates of the target companies’ EBITDA, based on available data for the closest period to current year or trailing twelve-month period leading up to announcement of the transaction.

In addition, in the ordinary course of their asset management, merchant banking and other business activities, affiliates of Rothschild & Co may trade in the securities of MasterBrand, American Woodmark and their respective affiliates, for their own accounts or for the accounts of their affiliates and customers, and may at any time hold a long or short position in such securities. Rothschild & Co does not engage in the securities trading business and has policies and procedures designed to prevent the flow of non-public information from its employees to employees of affiliates of Rothschild & Co that engage in the securities trading business.

Amending and supplementing the fourth sentence of the second full paragraph in the section entitled “The Merger – Opinion of American Woodmark’s Financial Advisor” on page 121 of the Joint Proxy Statement/Prospectus as follows:

With respect to the selected public companies analyses summarized below, no company or business used as a comparison was identical to American Woodmark or Master Brand nor, except as otherwise disclosed, were individual multiples derived from the selected companies independently determinative of the results of such analyses.

The implied terminal values of American Woodmark and MasterBrand were derived by applying to their respective normalized unlevered after-tax free cash flows for fiscal year 2029 (assuming normalized depreciation, change in net working capital, and capital expenditures in such fiscal year) a selected range of perpetuity growth rates of 2.0% to 2.5%. The present values (as of June 30, 2025) of American Woodmark’s and Masterbrand’s respective cash flows and terminal values were then calculated using a selected range of discount rates of 9.5% to 10.5% derived from a weighted average cost of capital calculation.
