Exhibit 99.1 Stepan Reports Second Quarter 2026 Results Northbrook, Illinois, July 29, 2026 — Stepan Company (NYSE: SCL) today reported: Second Quarter 2026 Highlights • Reported net income was $22.9 million, up 102% versus the prior year. Adjusted net income(1) was $27.1 million, up 126% versus the prior year. • EBITDA(2) was $69.1 million and Adjusted EBITDA(2) was $74.4 million, up 37% and 45% respectively, year-over-year. • Global sales volume was up 3% year-over-year. Organic sales volume was up 6% year-over-year. • Cash from Operations was $8.4 million during the quarter. Free cash flow(3) for the quarter was a negative $15.0 million, driven by higher working capital requirements. Excluding the impact of higher working capital, free cash flow was $32.7 million, up 69% versus the prior year. • Pre-tax earnings include a $5.1 million restructuring charge largely related to the previously announced closure of the Company’s Fieldsboro, NJ site and decommissioning of select assets at its Elwood (Millsdale), IL and Stalybridge, UK facilities. • The Company announced today a plan to reduce its global salaried workforce by approximately 100 positions. This action is part of the previously announced Project Catalyst efficiency initiative. The majority of this restructuring expense is expected to be recognized during the second half of 2026. The Company anticipates full year restructuring charges in the range of $75.0 to $80.0 million, which is in line with prior communications, with a projected cash impact between $14.0 and $18.0 million. First Half 2026 Highlights • Reported net income was a $18.5 million loss versus $31.1 million of income in the prior year. The current year loss is entirely due to a $70.5 million pre-tax restructuring charge. The cash impact associated with this restructuring charge was approximately $7.0 million year-to-date. Adjusted net income(1) was $37.4 million, up 20% versus the prior year. • EBITDA(2) was $52.7 million and Adjusted EBITDA(2) was $124.1 million. Adjusted EBITDA was up 14% year-over-year. • Organic sales volume was up 3% year-over-year. 1

“Quarterly earnings were up significantly driven by improved Surfactant and Polymer results. Second quarter adjusted EBITDA of $74.4 million was up 45% year-over-year due to global volume growth, margin recovery and Project Catalyst savings. We believe the quarter also benefited from customer pre-buys as a result of the global geopolitical situation. Surfactant and Polymer adjusted EBITDA were up 59% and 22%, respectively,” said Luis E. Rojo, President and Chief Executive Officer. “Surfactant organic sales volume was up 7% and Polymer sales volume was up 5% in the quarter. The Surfactant volume growth was broad-based and across all end markets and all regions. Within Polymers, the North American Rigid and Phthalic Anhydride businesses delivered double digit volume growth. We are pleased with the growth we achieved in several of our key strategic end markets despite ongoing global economic uncertainties and supply chain disruptions. We continue to execute Project Catalyst safely and in line with expectations. As part of the organizational-effectiveness component of Project Catalyst, today we announced a plan to reduce the Company’s global salaried workforce by around 100 roles before the end of the year. During the past few quarters, we took a disciplined and deliberate approach to minimize the impact of these actions through normal attrition, pausing external hiring and emphasizing internal talent. We are committed to supporting our affected colleagues through this transition in line with our People First culture.” Financial Summary Three Months EndedJune 30, Six Months EndedJune 30, ($ in thousands, except per share data) 2026 2025 %Change 2026 2025 %Change Net Sales $684,109 $594,689 15% $1,288,618 $1,187,944 8% Operating Income (Loss) $ 37,210 $ 17,965 107% $ (12,412) $ 46,253 NM Net Income (Loss) $ 22,911 $ 11,341 102% $ (18,495) $ 31,052 NM Earnings per Diluted Share $ 1.00 $ 0.50 100% $ (0.81) $ 1.36 NM Adjusted Net Income * $ 27,052 $ 11,952 126% $ 37,365 $ 31,262 20% Adjusted Earnings per Diluted Share * $ 1.18 $ 0.52 127% $ 1.63 $ 1.37 19% * See Table II for reconciliations of non-GAAP adjusted net income and adjusted earnings per diluted share.

This increase was primarily due to higher Surfactant and Polymer earnings driven by sales volume growth and margin recovery. • Surfactant net sales were $483.9 million for the quarter, up 18% versus the prior year. Selling prices were up 12% primarily due to pass through of higher raw material costs, improved product and customer mix, along with pricing actions. Global Sales volume was up 2% and organic sales volume increased 7%. All global regions recognized organic volume growth and our strategic end markets combined grew high single digits. Foreign currency translation positively impacted net sales by 4%. Surfactant adjusted EBITDA(2) for the quarter increased $20.4 million, or 59%, versus the prior year. This increase was primarily due to sales volume growth and margin recovery. 3

• Polymer net sales were $178.0 million for the quarter, a 9% increase versus the prior year. Selling prices were up 3%, primarily due to the pass-through of higher raw material costs and margin recovery. Sales volume increased 5% in the quarter. North American sales volume was up double digits, inclusive of significant growth in Spray Foam, partially offset by lower volumes in Europe and Asia. Foreign currency translation positively impacted net sales by 1% during the quarter. Polymer adjusted EBITDA(2) increased $5.6 million, or 22%, versus the prior year primarily due to sales volume growth and global margin improvement. • Specialty Products net sales were $22.2 million for the quarter, an 8% increase versus the prior year. Specialty Products volume increased 4% while adjusted EBITDA(2) decreased $0.2 million, or 3%. The slight decrease in adjusted EBITDA(2) was primarily due to less favorable product mix within the medium chain triglycerides product line that was mostly offset by higher earnings in the food and flavor business. Outlook “We believe we are positioned to continue delivering growth in all our key strategic businesses such as Crop Productivity, Oilfield, Tier 2/3 Surfactants and North American Polymers. We continue to execute on Project Catalyst, which is our comprehensive plan designed to further optimize our asset base and create a more productive and agile organization to enable balanced growth,” said Luis E. Rojo, President and Chief Executive Officer. “Despite the ongoing and significant market uncertainties and challenges, the organization is focused on executing our growth opportunities, productivity plans and cash interventions. With these actions and the strong first half results, we believe we will deliver full year Adjusted EBITDA growth, positive free cash flow and continue to de-leverage the balance sheet in 2026.” Notes (1) Adjusted net income and adjusted earnings per share are non-GAAP measures which exclude deferred compensation income/expense, certain environmental remediation-related costs as well as other significant and infrequent/non-recurring items.

The Company uses this non-GAAP information as an indicator of business performance and evaluates management’s effectiveness with specific reference to these indicators. Management believes that these non-GAAP financial measures provide useful supplemental information because they exclude non-operational items that affect comparability between years. These measures should be considered in addition to, not as substitutes for or superior to, measures of financial performance prepared in accordance with GAAP and may differ from similarly titled measures presented by other companies. The Company’s Annual Report on Form 10-K for the year ended December 31, 2025 contains additional information regarding the use of non-GAAP financial measures. Summary of Second Quarter 2026 Adjusted Net Income Items Adjusted net income excludes non-operational deferred compensation income/expense, certain environmental remediation costs and other significant and infrequent or non-recurring items. • Deferred Compensation: The second quarter of 2026 reported net income includes $0.1 million of after-tax expense versus $0.1 million of after-tax expense in the prior year. • Environmental Remediation: The second quarter of 2026 reported net income includes $0.1 million of after-tax expense versus $0.5 million of after-tax expense in the prior year. • Business Restructuring: The second quarter of 2026 reported net income includes $4.0 million of after-tax expense related to restructuring charges.
