Evaluating Expansion of Integrated Ammonia Platform to Meet Growing Regional Demand for Diesel Exhaust Fluid (DEF)

Appointed Patrick Day as SVP and CFO, effective April 27th

Parsippany, N.J., May 8, 2026 - AdvanSix (NYSE: ASIX), a vertically integrated chemistry company serving diverse end markets, today announced its financial results for the first quarter ending March 31, 2026. Overall, the Company navigated a dynamic market environment while progressing on key growth, cost savings and strategic initiatives.

First Quarter 2026 Summary

"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. "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. 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."

Summary first quarter 2026 financial results for the Company are included below:

Sales of $404 million in the quarter increased approximately 7% versus the prior year comprised of 6% volume growth and 1% favorable price. Sales volume growth was primarily driven by favorable Chemical Intermediates sales. Market-based pricing improved by 3% primarily driven by an increase in Plant Nutrients reflecting higher nitrogen pricing amid increased sulfur input costs. Raw material pass-through pricing was down 2% 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:

Total$404,183 100%$377,791 100%

Adjusted EBITDA of $4.8 million in the quarter decreased $46.9 million versus the prior year primarily driven by the absence of $26 million of prior year insurance proceeds, the unfavorable impact of higher sulfur and natural gas raw material prices, and higher plant costs primarily driven by utilities costs and $11 million of winter storm impact.

Adjusted earnings per share of ($0.50) decreased $1.43 versus the prior year driven primarily by the factors discussed above.

Cash flow from operations of ($15.3) million in the quarter decreased $26.8 million versus the prior year

primarily due to lower net income including the impact of insurance proceeds, partially offset by net changes in working capital. Capital expenditures of $35.9 million in the quarter increased $1.9 million versus the prior year, as expected.

Outlook

•Anticipate balanced U.S. ammonium sulfate supply and demand fundamentals in heart of domestic planting season amid meaningfully higher sulfur input costs

•Acetone spread over propylene costs expected to hold near cycle averages for the full year 2026

•Continue to optimize Nylon Solutions production output, inventories and sales volume mix in extended soft industrial end market environment

•Continue to expect Capital Expenditures of $75 to $95 million in 2026 versus approximately $116 million in 2025, reflecting risk-based prioritization of base investments and enterprise programs with continued progression of growth programs including SUSTAIN

•Now expect pre-tax income impact of plant turnarounds to be $17 t
