In February 2026, the U.S. Supreme Court ruled that the International Emergency Economic Powers Act ("IEEPA") does not authorize the imposition of tariffs. Subsequently, on April 20, 2026, U.S. Customs and Border Protection launched an administrative portal through which eligible importers could submit claims for refunds. During the three months ended June 30, 2026, the Company filed certain claims and received tariff refunds of $82 ($0.11 per share), and the benefit was recorded in Cost of sales. This benefit is reflected in Corporate and Other in the table above. The timing and amount of any further tariff refunds remain uncertain, and, accordingly, no benefit was recognized as of June 30, 2026 for any additional potential refunds related to IEEPA tariffs previously paid.
