On April 25, 2024, Masonite International Corporation, a British Columbia corporation (“Masonite”) held a special meeting of shareholders (the “Special Meeting”) to consider certain proposals related to the Arrangement Agreement, dated as of February 8, 2024 (as may be further amended or supplemented from time to time, the “Arrangement Agreement”), by and among Masonite, Owens Corning, a Delaware corporation (“Owens Corning”), MT Acquisition Co ULC, a British Columbia unlimited liability company and an indirect wholly owned subsidiary of Owens Corning (“Purchaser”), pursuant to which, among other things, Purchaser will acquire all of the issued and outstanding common shares of Masonite at a purchase price of $133.00 per share (the “Arrangement”). The Arrangement will be implemented by way of a statutory, court-approved plan of arrangement under Division 5 of Part 9 of the Business Corporations Act (British Columbia), with Masonite surviving as an indirect wholly owned subsidiary of Owens Corning.

As of the close of business on March 21, 2024, the record date for the Special Meeting (the “Record Date”), there were 21,975,850 shares of common stock of Masonite, no par value per share (“Common Shares”), outstanding and entitled to vote at the Special Meeting. At the Special Meeting, the holders of a total of 16,403,875 Common Shares were present in person or represented by proxy, representing approximately 74.65% of the shares entitled to vote, and at least three shareholders, constituting a quorum.

At the Special Meeting, the following proposals were considered. For more information on the following proposals, please refer to Masonite’s definitive proxy statement (the “Proxy Statement”) for the Special Meeting, filed with the United States Securities and Exchange Commission (the “SEC”) on March 22, 2024.

The proposals were approved by the requisite vote of Masonite’s shareholders. Sufficient votes were received to approve the Adjournment Proposal, but such an adjournment was not necessary in light of the approval of the Arrangement Resolution Proposal. The final voting results for each proposal are described below.

Pursuant to the terms of the Arrangement Agreement, the completion of the Arrangement remains subject to various conditions, including, among other things, (a) the issuance of interim and final orders by the Supreme Court of British Columbia approving the Arrangement, (b) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (as amended) and the receipt of certain required regulatory clearances and approvals in other jurisdictions under applicable antitrust and foreign direct investment laws and regulations and (c) the absence of any law, injunction, order or other judgment prohibiting, rendering illegal or permanently enjoining the consummation of the Arrangement, certain of which are still pending. Each of Masonite’s and Owens Corning’s obligation to consummate the Arrangement is also subject to the accuracy of the other party’s representations and warranties contained in the Arrangement Agreement (subject, with specified exceptions, to materiality or “Material Adverse Effect” standards), the other party’s performance of its covenants and agreements in the Arrangement Agreement in all material respects, and in the case of Purchaser’s obligation to consummate the Arrangement, the absence of any “Material Adverse Effect” on Masonite. As of the date of this Current Report on Form 8-K, the Arrangement is currently expected to close mid-2024, subject to the aforementioned closing conditions.

On April 25, 2024, Masonite issued a press release announcing the voting results of the Special Meeting. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
