Specialty chemical manufacturer Stepan Company posted double-digit North American volume gains across its rigid-foam, spray-foam, and phthalic-anhydride businesses in the third quarter of 2026. Net sales in the company’s Polymers segment surged 24% year over year to $178.7 million, up from $143.9 million in Q3 2025. Group net income climbed 64% to $17.8 million over the same period.
The operational momentum in Stepan’s Polymers segment was driven by North American insulation markets, counterbalancing lower demand across Europe and Asia to generate an overall 3% increase in global polymer sales volumes.
Pricing Mechanisms and Segment Profitability
The segment's operational delivery reflected strong pricing discipline and cost recovery:
Raw Material Cost Pass-Through: Average selling prices advanced 22%, primarily reflecting contractual mechanisms to pass through elevated raw material feedstock costs.
Foreign Exchange Impact: Negative currency translations trimmed segment sales by 1%.
Adjusted EBITDA: Polymers adjusted EBITDA rose 4% to $23.3 million, compared with $22.4 million in the prior-year period. Sustained North American volume deliveries fully absorbed the turnaround expenses tied to a statutory five-year maintenance shutdown at the company's German plant.
Operating Income: Polymer operating income increased 3% to $14.6 million.
Stepan’s polymer portfolio encompasses polyester polyols engineered for rigid polyurethane foam insulation in construction applications, alongside phthalic anhydride and specialty polyol formulations.
