Filing receipts
“The decrease in gross profit margin in the first quarter of 2026 as compared to the first quarter of 2025 was primarily due to lower sales volumes and prices for many of our major products across both segments, higher fuel costs and the recognition of a litigation charge of $67 million related to the settlement of certain PVC pipe antitrust litigation in the first quarter of 2026, as compared to the first quarter of 2025.”
“The increase in net loss and loss from operations was primarily due to lower sales volumes for PVC resin, caustic soda, chlorine and building products, lower sales prices for PVC resin, polyethylene and pipe and fittings, and higher fuel costs in the quarter ended March 31, 2026 as compared to March 31, 2025.”
“The net loss attributable to Westlake Corporation was also affected by higher interest expense in the quarter ended March 31, 2026, which resulted from a higher average debt balance as compared to the quarter ended March 31, 2025.”
