AdvanSix (NYSE:ASIX), an integrated chemistry company serving diverse end markets, today announced its financial results for the fourth quarter and full year ending December 31, 2025. Overall, the Company had a strong finish to the year with its focus on optimizing operational and commercial performance to successfully navigate dynamic industry conditions.

Full Year 2025 Summary

Summary full year 2025 financial results for the Company are included below:

Sales by product line and approximate percentage of total sales are included below:

"The AdvanSix team executed well to close out 2025. We delivered full year Adjusted EBITDA of $157 million and generated positive free cash flow in a year characterized by continued cyclical trough market conditions for Nylon Solutions, robust Plant Nutrients supply and demand fundamentals amid a higher raw material input cost environment, and mixed Chemical Intermediates industry conditions with lower net pricing as anticipated," said Erin Kane, president and CEO of AdvanSix. "We generated these results while successfully executing our planned plant turnarounds, delivering record annual production across both of our key ammonia and sulfuric acid unit operations, funding key growth and enterprise initiatives including our SUSTAIN program, claiming additional 45Q carbon capture tax credits, receiving final settlement proceeds related to the 2019 PES supplier shutdown claim, preserving our competitive dividend and maintaining conservative debt leverage levels."

Fourth Quarter 2025 Summary

Summary fourth quarter 2025 financial results for the Company are included below:

Sales of $360 million in the quarter increased approximately 9% versus the prior year. Sales volume increased approximately 11% primarily driven by the prior year impact of the 4Q24 extended planned turnaround. Market-based pricing was favorable by approximately 2% driven by continued strength in Plant Nutrients, reflecting favorable North American ammonium sulfate supply and demand conditions, partially offset by lower acetone prices as anticipated. Raw material pass-through pricing was down approximately 4% following a net cost decrease in benzene and propylene (inputs to cumene which is a key feedstock to our products).

Sales by product line and approximate percentage of total sales are included below:

Adjusted EBITDA of $24.8 million in the quarter increased $14.5 million versus the prior year primarily driven by the favorable year-over-year volume and cost impact of plant turnarounds, partially offset by a decline in Chemical Intermediates pricing, net of raw material costs.

Adjusted earnings per share of $0.03 decreased $0.06 versus the prior year driven primarily by the factors discussed above, which were more than offset by the $9.7 million in 45Q carbon capture tax credits claimed in the fourth quarter of 2024.

Cash flow from operations of $63.7 million in the quarter decreased $0.4 million versus the prior year primarily due to lower ammonium sulfate pre-buy cash advances partially offset by other changes in working capital. Capital expenditures of $27.6 million in the quarter decreased $6.8 million versus the prior year.

Outlook

• Anticipate continued strength in Plant Nutrients supply and demand fundamentals amid meaningfully higher sulfur input costs
• Acetone spread over propylene costs expected to hold near cycle averages; Anti-dumping duties into U.S. renewed for another five years
• Navigating an extended trough in the nylon cycle - focused on controllable levers to optimize performance
• Expect Capital Expenditures of $75 to $95 million in 2026 versus approximately $116 million in 2025, reflecting a risk-based prioritization of base investments and enterprise programs with continued progression of growth programs including SUSTAIN
• Expect pre-tax income impact of plant turnarounds to be $20 to $25 million in 2026 versus approximately $25 million in 2025
• Expect cash flow benefit in 2026 and beyond from 45Q carbon capture tax credits and 100% bonus depreciation

"The end market environment entering 2026 remains mixed overall. We've seen continued strength in Plant Nutrients and acetone margins remain near cycle averages, while nylon has plateaued in its trough. Conversely, there have been several recent industry announcements pointing to capacity rationalization and lower operating rates, which we believe should lead to more favorable supply and demand conditions over time. We remain highly focused on delivering on controllable levers including continued optimization of production output and sales volume mix while driving productivity to support through-cycle profitability. We have embarked on a multi-year non-manpower fixed cost savings program targeting approximately $30 million of annual savings. In addition, we now anticipate capital expenditures to be in the range of $75 to $95 million in 2026 driven by a risk-based prioritization of our capital investments and keen focus on cash flow generation and conversion. Our strategic initiatives, unique combination of assets and business model are core to our durable competitive advantage and long-term positioning," concluded Kane.

Dividend

The Company's Board of Directors declared a quarterly cash dividend of $0.16 per share on the Company's common stock. The dividend is payable on March 23, 2026 to stockholders of record as of the close of business on March 9, 2026.
