Owens Corning — Call Transcript 2026

Good morning, and welcome to the Owens Corning 2026 Annual Meeting of Stockholders. I would now like to introduce the first presenter, Brian Chambers, Chair and Chief Executive Officer. Good morning, everyone. I'm pleased to welcome you to Owens Corning's 2026 Annual Meeting of Stockholders. We appreciate your attendance, your interest, and most importantly, your support of Owens Corning. Before we begin, I would like to thank our global teams who continue to successfully execute our enterprise strategy in 2025, despite challenging markets, delivering strong margins and making great progress on key initiatives to enhance our operational efficiency and accelerate our organic growth. Now, I will begin our annual meeting by calling it to order. I will serve as Chair of the meeting. After introducing the directors and others in attendance, we will focus on the meeting proposals. Now, I would like to introduce my fellow members of the Board of Directors of Owens Corning, who are in attendance today. We welcome Edward F. Lonergan, Lead Independent Director, Michelle Collins, Eduardo Cordeiro, Adrienne D. Elsner, Alfred E. Festa, Paul E. Martin, Suzanne P. Nimocks, and John D. Williams. Also attending the meeting is Holly Bowman, a representative from PricewaterhouseCoopers, our independent registered public accounting firm. We're also joined by Gina Beredo, Owens Corning's Executive Vice President, Chief Administrative Officer, and General Counsel, who will serve as the Secretary of the meeting. In addition, our Board of Directors has appointed Tracy Oates, a representative from Broadridge Financial Solutions, to serve as the Inspector of Election for this meeting. I request that she file her oath of office with the Secretary of the meeting for inclusion in the minutes of this meeting. Gina will now report on the distribution of the notice of the meeting and proxy materials. Thank you, Brian. The Board fixed February 17th, 2026, as the record date for determining stockholders entitled to vote at this meeting. Broadridge has certified by affidavit that the notice of the meeting, the proxy statement, and the 2025 Annual Report were mailed on or about March 13th, 2026, to all stockholders as of the record date. Broadridge's affidavit will be incorporated into the meeting minutes. I also have the list of record holders of common stock as of the close of business on February 17th, 2026. I will file a copy of this list with the company records. The stockholder list shows that as of the record date, there were 80,383,165 shares of common stock outstanding and entitled to vote at this meeting. I have been informed by the Inspector of Election that there are, represented in person or by proxy, shares of common stock constituting a majority of the total shares entitled to vote at this meeting. Therefore, a quorum is present for purposes of transacting business and the meeting may proceed. Thank you, Gina. On the basis of the reports of the Secretary and the Inspector of Election, I find that proper notice has been given and that a quorum is present. Accordingly, this meeting has been properly convened, and I declare the polls open. Now, I will present the matters to be voted upon. The first item is the election of Directors. At this meeting, we will be electing each of the nine nominees for Director for a one-year term expiring at the 2027 Annual Meeting of Stockholders. The nominees are Brian Chambers, Michelle Collins, Eduardo Cordeiro, Adrienne D. Elsner, Alfred E. Festa, Edward F. Lonergan, Paul E. Martin, Suzanne P. Nimocks, and John D. Williams. No other nominations have been received in accordance with our bylaws, and the nominations are now closed. The second proposal is the ratification of the selection of PricewaterhouseCoopers LLP as the company's independent registered public accounting firm for Fiscal Year 2026. The final proposal asks stockholders to approve an advisory resolution on the Fiscal Year 2025 compensation of our Named Executive Officers, as described in the Proxy Statement. While our Board and Compensation Committee intend to carefully consider the stockholder vote resulting from the proposal, the final vote will not be binding and is advisory in nature. Now that everyone has had the opportunity to vote, I declare the polls closed for the 2026 Annual Meeting of Stockholders. Gina, please report on the results of the voting. I have been advised by the Inspector of Election that based on a preliminary tabulation of the votes, each of the nine nominees for Director in the proxy statement has received a majority of votes cast and has been elected to serve for a one-year term expiring at the 2027 Annual Meeting of Stockholders, and each of the other Company proposals were approved. We will report the final vote results in accordance with the relevant securities laws. Thank you, Gina. Thank you to our stockholders for their participation in today's meeting and for their votes. Before we close, I would like to note that we did not receive any questions from stockholders for this annual meeting. Therefore, I declare that the 2026 Annual Meeting of Stockholders has concluded and is adjourned. I want to thank everyone who made time to join us on today's call and for your ongoing support of Owens Corning. Thank you, and have a safe day. Thank you.
