AdvanSix Q2 2026 Earnings: Sales Rise but Plant Nutrients Weigh on Profit

AdvanSix (NYSE: ASIX) reported Q2 2026 sales of $421.3 million, up 3% from $410.0 million a year earlier, while diluted EPS fell to $0.12 from $1.15. The revenue increase was pricing-led, with an 18% favorable pricing effect offsetting a 15% volume decline, while weaker Plant Nutrients demand and reduced production output weighed on earnings. Operating cash flow was $10.0 million, but free cash flow remained negative at $10.7 million.

Core financial results

For the quarter ended June 30, 2026, higher sales did not translate into higher profit. Adjusted EBITDA declined 43%, its margin contracted by 600 basis points, and net income fell 90% as lower volume, production output and a higher effective tax rate outweighed lower SG&A expense.

*Gross profit and gross margin are calculated from reported sales and cost of goods sold. Adjusted EPS, adjusted EBITDA and free cash flow are non-GAAP measures.

Business and product-line performance

Product-line results diverged considerably. Growth in Nylon and Chemical Intermediates more than offset lower Plant Nutrients and Caprolactam sales at the consolidated revenue level, but the Plant Nutrients volume decline was a major drag on profitability.

Management attributed the Plant Nutrients weakness primarily to challenging farmer economics and lower in-season fertilizer purchases during the spring planting season. Nylon Solutions and Chemical Intermediates performed at or above management’s expectations despite subdued industrial end-market demand.

Pricing protected revenue, but not earnings

AdvanSix’s 18% favorable pricing effect included 13% from raw-material pass-through pricing after benzene and propylene costs increased. Another 5% came from market-based pricing, primarily higher Plant Nutrients pricing associated with nitrogen markets and increased sulfur input costs.

Those pricing mechanisms supported reported sales, but they did not offset the earnings effects of the 15% volume decline and reduced production output. Cost of goods sold rose to $390.2 million from $351.3 million even as sales increased only 3%, contributing to the contraction in calculated gross margin.

A planned reduction in SG&A expense provided a partial offset, with spending declining to $22.1 million from $25.4 million. Below the operating line, adjusted EPS also faced a higher effective tax rate because the prior-year quarter benefited from 45Q carbon-capture tax credits.

Cash flow and balance sheet

Operating cash flow fell by $11.1 million to $10.0 million, primarily because of lower net income. Capital expenditures declined to $20.7 million from $28.3 million, but still exceeded operating cash generation, resulting in negative free cash flow of $10.7 million.

At June 30, cash and cash equivalents stood at $7.2 million, down from $19.8 million at the end of 2025. Inventories decreased to $194.1 million from $236.5 million, while accounts and other receivables increased to $187.4 million from $154.1 million. The long-term line-of-credit balance rose to $275.0 million from $215.0 million over the same period, placing greater importance on the cash-flow improvement management expects in the second half.

2026 outlook

AdvanSix reaffirmed its capital-spending range and now expects approximately $17 million of pre-tax impact from planned plant turnarounds. Management also expects sequential cash-flow improvement in the second half as the capital-spending run rate declines and working-capital and cash-tax factors become more favorable.

For Q3 2026, the North American ammonium sulfate fill program is expected to produce a sequential decline in domestic pricing amid competitive conditions and continued high sulfur input costs. AdvanSix also expects the full-year acetone spread over propylene costs to remain near cycle averages and plans to keep optimizing Nylon Solutions production, inventories and sales mix during the extended period of soft industrial demand.

Recent insider transactions

The supplied insider summary shows no open-market purchases or sales during the latest six-month period, leaving net shares purchased or sold at zero. Total insider holdings were reported at approximately 849,750 shares, while the most recent reported transactions were stock awards rather than market purchases.

These grants should not be interpreted as open-market buying or as evidence of insiders’ views on valuation.

Risks investors should monitor

• Plant Nutrients demand and pricing: Weak farmer profitability already reduced fertilizer purchases, while management expects domestic ammonium sulfate pricing to decline sequentially in Q3.
• Input-cost pressure: Higher benzene, propylene and sulfur costs are supporting pass-through pricing but remain a challenge for profitability when volumes and production output decline.
• Soft industrial demand: The extended weakness affecting Nylon Solutions and Chemical Intermediates could continue to constrain production, inventory management and sales mix.
• Cash conversion: Free cash flow remained negative, cash declined and the line-of-credit balance increased. The expected second-half recovery depends on lower capital spending and anticipated working-capital and tax benefits.
• Turnaround costs: Planned plant turnarounds are expected to reduce 2026 pre-tax income by approximately $17 million.

Summary

AdvanSix preserved modest revenue growth in Q2 2026 through raw-material pass-through and market-based pricing, but lower Plant Nutrients volume, reduced production output and a less favorable tax comparison caused a much steeper decline in profit. The next key tests are the expected Q3 ammonium sulfate pricing pressure and whether lower capital spending and working-capital tailwinds produce the second-half cash-flow improvement management anticipates.
