Stepan Increases CASE Polyol Prices

November 18, 2021

Dear Valued Customer

Due to the continued escalation of costs to manufacture products including raw materials,
transportation, labor and energy, the price of CASE Stepanpol® polyols in the Americas will increase
by up to $0.20/lbs depending on grades. This increase will be effective for all shipments on January
1, 2022 or as contracts allow.

Your Stepan Sales Representative will be in contact with you to address any questions or concerns.
We appreciate your support and value your continued business.
