Masonite Shareholders Approve Transaction with Owens Corning

Masonite International Corporation (“Masonite”) announced that its shareholders have voted to approve the Company’s proposed transaction with Owens Corning at its Special Meeting of Shareholders. As previously announced, under the terms of the transaction, Masonite shareholders will receive $133.00 per share in cash in connection with the closing of the transaction.

Howard Heckes, President and Chief Executive Officer of Masonite, said, “We thank our shareholders for their overwhelming support of this transaction. Together with Owens Corning, we will be even better positioned to continue transforming the door industry through the execution of our proven Doors That Do More™ strategy. We will continue working to complete the transaction and are committed to a smooth transition for our stakeholders.”

Masonite continues to expect to complete the transaction in mid-2024, subject to remaining regulatory approvals and other customary closing conditions including issuance of the final order by the Supreme Court of British Columbia approving the plan of arrangement.
