SHERWIN WILLIAMS CO

SEC regulations require disclosure of certain environmental matters when a governmental authority is a party to the proceedings and such proceedings involve potential monetary sanctions that the Company reasonably believes will exceed a specified threshold. Pursuant to these regulations, the Company uses a threshold of $1 million for purposes of determining whether disclosure of any such proceedings is required.

On May 12, 2025, a subsidiary of the Company, The Sherwin-Williams Manufacturing Company (SWM), was served with a Petition and Application for Injunctive Relief from the State of Texas, through its Attorney General on behalf of the Texas Commission on Environmental Quality, filed in the District Court of Travis County, Texas, and on January 30, 2026, the State filed a First Amended Petition and Application for Injunctive Relief (together, the Petition). The Petition alleges that one of SWM’s Garland, Texas facility’s past operations violated Texas environmental regulations related to air and water emissions, and includes events related to the fire experienced at that facility on August 8, 2023. The Petition seeks injunctive relief, civil penalties, reimbursement of response costs, expenses, and attorney fees and costs. SWM denies the violations and claims for relief as alleged and intends to vigorously defend these claims if SWM is unable to resolve this matter to the mutual satisfaction of the parties.
