Underlying organic sales growth plus the addition of Magenta's fiber colorant business and Kraton's TPE business was more than offset by lower year-over-year selling prices in Distribution, PP&S, and Designed Structures and Solutions (DSS), due to lower hydro-carbon based raw material costs.

Polymers are a class of organic materials that are generally produced by converting natural gas or crude oil derivatives into monomers, such as ethylene, propylene, and styrene. The ongoing conflict between Russia and Ukraine has impacted global energy markets, particularly in Europe, leading to high volatility and increasing prices for crude oil, natural gas and other energy supplies.

Strong perforff mance in these segments helped to overcome several headwinds, including: lower selling prices in Distribution and PPS due to hydro-carbon based raw material deflatff ion; unfavff orable foreign exchange; a decline in demand in certain industries, such as oil and gas, heavy truck and agriculture; and weaker performance by our Designed Structures and Solutions (“DSS”) business.
