Stepan Reports Fourth Quarter and Full Year 2025 Results

Northbrook, Illinois, February 23, 2026 -- Stepan Company (NYSE: SCL) today reported:

Fourth Quarter 2025 Highlights

Full Year 2025 Highlights

“2025 was a transformational year for Stepan as we divested two plant sites and completed preliminary work that has positioned us to further optimize our footprint and asset base in 2026. Despite many challenges in 2025, we delivered growth in several of our core businesses, advanced several strategic initiatives and have an operational plan in place to accelerate profitable growth moving forward. Full year adjusted EBITDA grew 6% versus prior year despite a significant increase in oleochemical raw material costs and start-up expenses at our Pasadena site. Volume grew 1%, organic volume grew 2% and net sales were up 7% driven by pricing actions and favorable product and customer mix. We delivered $25.4 million of free cash flow and increased our dividend for the 58th consecutive year, while reducing our Net Debt by $31.7 million and our Leverage Ratio to 2.5," said Luis E. Rojo, President and Chief Executive Officer. "Fourth quarter adjusted EBITDA was down 3% primarily due to a challenging North American Surfactant environment. We continue to recover margins in Surfactants despite an unprecedented run-up in raw material costs.

Polymer volume was up 11% as our Rigid, Specialty Polyols and Phthalic Anhydride businesses all delivered volume growth. I want to personally thank all of our Stepan colleagues around the world for their hard work and resilience during the year."

Financial Summary

Percentage Change in Net Sales

Net sales in the fourth quarter of 2025 increased 5% year-over-year. This increase reflects higher selling prices, that were mainly attributable to the pass-through of higher raw material costs and more favorable product mix, and the favorable impact of foreign currency translation. A 3% decline in sales volume partially offset the above.

Segment Results

Consolidated adjusted EBITDA(2) decreased $1.2 million, or 3%, in the quarter. This decrease was primarily due to a 7% decline in Surfactant sales volume, driven by lower demand in the global commodity Laundry & Cleaning end markets. Polymer sales volume growth of 11% and lower corporate expenses partially offset the above.

.

Income Taxes

The Company's effective tax rate was 21.7% in 2025 versus 16.7% in 2024. This increase was primarily attributable to the non-recurrence of favorable deferred tax adjustments recognized in 2024.

Outlook

“As we look forward to 2026, we remain focused on delivering superior shareholder returns with a balanced approach between top line growth and productivity cost out efforts. Today we announced Project Catalyst, which is a comprehensive plan designed to further optimize our asset base and create a more productive and agile organization to enable growth. Project Catalyst is expected to deliver approximately $100 million in pre-tax savings over the next two years. As part of Project Catalyst, Stepan will close its Fieldsboro, NJ site and decommission select assets at its Millsdale, IL and Stalybridge, UK facilities. Additionally, we are analyzing other opportunities to optimize our asset base, organization structure and operating model. We will announce future interventions once approved plans are in place," said Luis E. Rojo, President and Chief Executive Officer. "With these actions, we believe we are positioned to deliver full year Adjusted EBITDA growth and positive free cash flow in 2026, despite the ongoing market and tariff uncertainties."
