Huntsman HUN Performance Products — Restructuring Charges

Beginning in the first quarter of 2024, our Advanced Materials segment implemented a restructuring program to optimize the segment’s manufacturing processes and cost structure in the U.S. to better align with future market opportunities. During the first quarter of 2026, this program was expanded to further realign and reduce the segment’s U.S. manufacturing and other global organizational structure costs. In connection with this restructuring program, we recorded net restructuring expense of approximately $4 million and $1 million during the three months ended March 31, 2026 and 2025, respectively, primarily related to workforce reductions and accelerated depreciation. We expect to record further restructuring expenses of approximately $7 million through 2027, primarily related to accelerated depreciation and workforce reductions.
