Segment Performance

• Composites net sales decreased 14% to $620 million in second-quarter 2023 compared with second-quarter 2022, primarily due to lower volumes and the expected net headwind from the impact of previously announced divestitures and acquisitions. EBIT decreased $67 million to $87 million while maintaining 14% EBIT margins and 21% EBITDA margins, on the impact of lower sales volumes and the resulting production downtime. Additionally, the net impact from the divestitures and acquisitions contributed to the year-over-year EBIT decline. Positive price realization and favorable delivery more than offset input cost inflation.

• Insulation net sales decreased 3% to $905 million in second-quarter 2023 compared with second-quarter 2022, primarily due to lower volumes partially offset by positive price realization and favorable product and customer mix. EBIT increased $6 million to $163 million, expanding EBIT margins to 18% and EBITDA margins to 24%, on positive price realization and favorable customer and product mix, which more than offset lower volumes, input cost inflation, and higher manufacturing costs.
