AdvanSix posted higher sales in the first quarter of 2026 but swung to a loss as raw material costs surged and operational headwinds weighed on margins.
The vertically integrated chemical producer reported Q1 sales of $404 million, up 7% year over year, driven by stronger volumes and pricing gains in key segments. But profitability took a sharp hit, with the company posting a net loss of $15.5 million, compared with a profit of $23.3 million a year earlier.
Adjusted EBITDA plunged to $4.8 million, down dramatically from $51.6 million a year earlier, reflecting higher input costs, winter storm disruptions, and the absence of prior-year insurance benefits.
“The AdvanSix team delivered a solid first quarter performance consistent with our expectations while navigating a number of headwinds, including the early quarter winter storm-related impacts and new geopolitical challenges amid continued subdued industrial end market demand,” said Erin Kane, president and CEO of AdvanSix.
Kane highlighted strength in volumes and pricing in parts of the portfolio, noting: “We generated 7% sales growth year-over-year, supported by improvements in Chemical Intermediates volume and Plant Nutrients market pricing, partially offsetting the margin impacts driven by increased sulfur and natural gas costs.”
She added that the company remains positioned for improvement heading into the next quarter.
“We remain well positioned to serve our customers across our diversified portfolio including fertilizer as the domestic planting season progresses, in chemical intermediates amid a tightening acetone global supply and demand environment, and across a modestly recovering nylon industry supporting expected meaningful sequential performance improvement into the second quarter.”
The earnings decline was driven by a mix of factors: higher sulfur and natural gas costs, winter storm disruptions estimated at $11 million, and the absence of roughly $26 million in insurance proceeds from the prior year.
Operating cash flow also turned negative at ($15.3 million), compared with a positive $11.4 million a year earlier. Free cash flow worsened to ($51.3 million).
Despite weaker earnings, AdvanSix is pushing forward with strategic investments, including a potential expansion of its ammonia platform to meet rising demand for diesel exhaust fluid (DEF).
The company is currently advancing engineering work with a final investment decision expected in 2027 and potential startup in 2029.
“Our strategic initiatives, unique combination of assets and business model are core to our durable competitive advantage and long-term positioning,” Kane said, pointing to the company’s integrated production system and cost-saving programs.
