Softening demand conditions in the fourth quarter most heavily impacted the Performance Products and Solutions (PP&S) and Specialty Engineered Materials (SEM) segments. Specifically, end markets negatively impacting PP&S were building & construction and appliance.

This quarter, our Specialty Engineered Materials, Performance Products & Solutions (PP&S) and Distribution segments led the way, as all three achieved year-over-year increases in operating income." Underlying organic sales growth, plus contributions from the company's recently acquired businesses, offset 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.

The company noted customers are citing concerns over tariffs and persistent inflation as possible drivers of these demand conditions, which most heavily impacted the Performance Products and Solutions (PP&S) and Distribution segments.  If so, lower operating income from PP&S and Distribution could offset continued growth in Color, Additives & Inks and Engineered Materials in the fourth quarter.
