AdvanSix (NYSE:ASIX) delivered mixed results for the fourth quarter of 2025, posting healthy year-over-year sales growth and stronger operating metrics, though earnings failed to meet analyst expectations.
Shares ticked up 0.11% in after-hours trading following the announcement.
Quarterly revenue totaled $359.9 million, marking a 9% increase from $329.1 million in the same period last year. The growth was largely driven by an 11% rise in volumes and supportive pricing trends within the company’s Plant Nutrients segment.
Despite the revenue gains, profitability disappointed. On a GAAP basis, the company reported a loss per share of $0.10. Adjusted earnings per share came in at $0.03, significantly below the $0.43 consensus estimate and down from $0.09 a year earlier.
Adjusted EBITDA more than doubled to $24.8 million from $10.2 million in the prior-year quarter, with margins expanding to 6.9% from 3.1%. The improvement reflected better plant utilization following turnaround activity in the previous year. Operating cash flow remained robust at $63.7 million, while free cash flow reached $36.1 million during the quarter.
President and CEO Erin Kane pointed to strong execution in a challenging environment. “The AdvanSix team executed well to close out 2025.’”
He added, “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… and mixed Chemical Intermediates industry conditions,” Kane said.
For the full year, AdvanSix recorded revenue of $1.52 billion, slightly higher than in 2024, and net income of $49.3 million, or $1.80 per diluted share. Adjusted EBITDA rose to $156.8 million, with margin improving to 10.3%.
Looking ahead to 2026, management anticipates ongoing strength in the Plant Nutrients business, capital expenditures between $75 million and $95 million — down from roughly $116 million in 2025 — and additional cash flow support from 45Q carbon capture tax credits and accelerated depreciation benefits.
The company also declared a quarterly dividend of $0.16 per share, payable on March 23, 2026.
