#### DELINQUENT SECTION 16(a) REPORTS
Section 16(a) of the Exchange Act and SEC regulations require Owens Corning’s directors, certain officers and greater than ten percent stockholders to file reports of ownership on Form 3 and changes in ownership on Forms 4 or 5 with the SEC. Owens Corning undertakes to file such forms on behalf of our current reporting directors and officers pursuant to a power of attorney given to certain attorneys-in-fact. Reporting directors, officers and greater than ten percent stockholders are also required by the SEC rules to furnish Owens Corning with copies of all Section 16(a) reports they file.

Except as disclosed below, based solely on our review of copies of such reports received and/or written representations from such reporting directors, officers, and greater than ten percent stockholders, Owens Corning believes that all Section 16(a) filing requirements applicable to its reporting directors, officers, and greater than ten percent stockholders were complied with during fiscal year 2024, other than one Form 4 for Christopher O. Ball, our President, Doors, reporting one transaction related to the shares withheld upon vesting of RSUs to satisfy tax withholding obligations, which was filed one day late due to technical difficulties when filing.
