Westlake Q4 Report 2022

Fourth quarter 2022 net income of $232 million decreased by $169 million sequentially as compared to the third quarter of 2022. The sequential decrease in net income compared to the prior quarter was primarily due to lower sales prices in Performance Materials, inclusive of negative mix shifts towards export markets; and lower Housing and Infrastructure Products volumes due to both seasonal trends and continued slowing demand. These impacts were partially offset by higher sales prices for caustic soda.
