NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands, except share and per share amounts and as otherwise noted)

1. Organization, Operations and Basis of Presentation

Description of Business

AdvanSix Inc. ("AdvanSix," the "Company," "we" or "our") is a diversified chemistry company that produces essential materials for our customers in a wide variety of end markets and applications that touch people’s lives. Our integrated value chain of our five U.S.-based manufacturing facilities plays a critical role in global supply chains and enables us to innovate and deliver essential products for our customers across building and construction, fertilizers, agrochemicals, plastics, solvents, packaging, paints, coatings, adhesives, electronics and other end markets. Guided by our core values of Safety, Integrity, Accountability and Respect, AdvanSix strives to deliver best-in-class customer experiences and differentiated products in the industries of nylon solutions, plant nutrients, and chemical intermediates.

Basis of Presentation

The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the Company's financial position as of September 30, 2025, and its results of operations for the three and nine months ended September 30, 2025 and 2024 and cash flows for the nine months ended September 30, 2025 and 2024. The year-end Condensed Consolidated Balance Sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. The results of operations of any interim period are not necessarily indicative of the results of operations to be expected for the full fiscal year. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. All intercompany transactions have been eliminated.

Certain prior period amounts have been reclassified for consistency with the current period presentation.

It is our practice to establish actual quarterly closing dates using a predetermined fiscal calendar, which requires our businesses to close their books on a Saturday in order to minimize the potentially disruptive effects of quarterly closing on our business processes. Historically, the effects of this practice have generally not been significant to reported results for any quarter and only existed within a reporting year. In the event that differences in actual closing dates are material to year-over-year comparisons of quarterly or year-to-date results, we will provide the appropriate disclosures. Our actual closing dates for the three and nine months ended September 30, 2025 and 2024 were September 27, 2025 and September 28, 2024, respectively.

Liabilities to creditors to whom we have issued checks that remained outstanding at September 30, 2025 and December 31, 2024 aggregated to $6.4 million and $7.3 million, respectively. These were included in Cash and cash equivalents and Accounts payable in the Condensed Consolidated Balance Sheets.

The Company previously reported a business impact associated with the June 2019 fire that shut down the Philadelphia Energy Solutions refinery in Philadelphia, Pennsylvania. The Company actively pursued a business interruption claim and reached a final omnibus settlement in January 2025 which resulted in insurance settlement proceeds of approximately $26 million in the first quarter of 2025. The total aggregate insurance proceeds since the original claim submission are approximately $39 million. The proceeds have been recognized as a reduction to Costs of Goods Sold on the Condensed Consolidated Statements of Operations in the periods in which they were received.

As of September 30, 2025, the Company has repurchased a total of 6,313,789 shares of common stock, including 1,068,333 shares withheld to cover tax withholding obligations in connection with the vesting of awards, for an aggregate of $194.1 million at a weighted average market price of $30.74 per share. As of September 30, 2025, approximately $62.0 million remained available for share repurchases under the current authorization approved by the Company's Board of Directors (the "Board") on February 17, 2023. During the period October 1, 2025 through October 31, 2025, no additional shares were repurchased for tax withholding obligations or under the currently authorized repurchase program.

Repurchases may be made from time to time on the open market in accordance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), including through the use of trading plans intended to qualify under Rule 10b5-1 of the Exchange Act. The size and timing of these repurchases will depend on pricing, market and economic conditions,

legal and contractual requirements and other factors. The share repurchase program has no expiration date and may be modified, suspended or discontinued at any time. The par value of the shares repurchased is applied to Treasury stock and the excess of the purchase price over par value is applied to Additional paid-in capital.

2. Recent Accounting Pronouncements

Recent Accounting Pronouncements – The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (“FASB”). ASUs not discussed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations.

In August 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Practical Expedient for Measuring Expected Credit Losses on Certain Financial Assets. The amendments in this ASU provide a simplified approach for estimating credit losses on certain financial assets, including current accounts receivable, by permitting entities to elect a practical expedient when measuring expected credit losses. Under current guidance, when estimating expected credit losses, an entity must (1) consider not only historical loss experience but also adjust that information to reflect current conditions and reasonable and supportable forecasts and (2) include a measure of expected credit loss even if that risk is remote. The amendments in this ASU allow an entity, as a practical expedient, to: (1) Assume that current conditions as of the balance sheet date will remain unchanged over the remaining life of the financial asset; and (2) continue to adjust historical loss information to reflect current conditions to the extent that historical information does not already do so. The amendments are effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual periods. Early adoption is permitted in any interim or annual period for which financial statements have not yet been issued or made available for issuance. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments in this ASU require disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity will: (1) disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil-and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)-(e); (2) include certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as other disaggregation requirements; (3) disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively; and (4) disclose the total amount of selling expense and, in annual reporting periods, an entity's definition of selling expense. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this ASU should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this ASU or (2) retrospectively to any or all prior periods presented in the financial statements. The Company is evaluating the pronouncement and does not expect adoption to have a material impact on the Company's consolidated financial position or results of operations.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this ASU require that public business entities, on an annual basis, disclose specific categories in the rate reconciliation and provide additional information for reconciling items that are equal to or greater than 5 percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate. The amendments also require that the Company disclose the following (net of refunds received): (1) the amount of income taxes paid disaggregated by federal (national), state, and foreign taxes and (2) the amount of income taxes paid disaggregated by individual jurisdictions in which income taxes paid is equal to or greater than 5 percent of total income taxes paid. Additionally, the amendments in this update eliminate the requirement for all entities to disclose the nature and estimate of the range of the reasonably possible change in the unrecognized tax benefits balance in the next 12 months or to make a statement that an estimate of the range cannot be made, and remove the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of the exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures. This pronouncement is effective for annual periods beginning after December 31, 2024 and the required disclosures will be adopted in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

(Dollars in thousands, except share and per share amounts and as otherwise noted)

Revenue Recognition

AdvanSix serves around 390 customers annually, primarily in the United States, spanning a wide variety of industries worldwide. For the nine months ended September 30, 2025 and 2024, the Company's ten largest customers accounted for approximately 41% and 38% of total sales, respectively.

We typically sell to customers under master service agreements, with primarily one-year terms, or by purchase orders. We have historically experienced low customer turnover and have long-standing customer relationships, which span decades. Our largest customer is Shaw Industries Group, Inc. (“Shaw”), a significant consumer of caprolactam and Nylon 6 resin, to whom we sell under a long-term agreement. For the three months ended September 30, 2025 and 2024, the Company's sales to Shaw were 12% and 10% of our total sales, respectively. For the nine months ended September 30, 2025 and 2024, the Company's sales to Shaw were 10% and 9% of our total sales, respectively.

The Company's revenue by product line, and related approximate percentage of total sales, for the three and nine months ended September 30, 2025 and 2024 were as follows:

The computation of basic and diluted earnings per share ("EPS") is based on Net income (loss) divided by the basic weighted average number of common shares outstanding and, where appropriate, diluted weighted average number of common shares outstanding, respectively. The details of the basic and diluted EPS calculations for the three and nine months ended September 30, 2025 and 2024 were as follows:

For each of the nine months ended September 30, 2025 and September 30, 2024, the Company recorded amortization expense on intangible assets of $2.3 million.

9. Commitments and Contingencies

The Company is subject to a number of lawsuits, investigations and disputes, some of which may involve substantial amounts claimed, arising out of the conduct of the Company or other third-parties in the normal and ordinary course of business. A liability is recognized for any contingency that is probable of occurrence and reasonably estimable. The Company continually assesses the likelihood of adverse judgments or outcomes in these matters, as well as potential ranges of possible losses, based on an analysis of each matter with the assistance of legal counsel and, if applicable, other experts.

Given the uncertainty inherent in such lawsuits, investigations and disputes, the Company does not believe it is possible to develop estimates of reasonably possible loss in excess of current accruals for these matters. Considering the Company’s past experience and existing accruals, the Company does not expect the outcome of these matters, either individually or in the aggregate, to have a material adverse effect on the Company’s consolidated financial position or results of operations. Potential liabilities are subject to change due to new developments, changes in settlement strategy or the impact of evidentiary requirements, which could cause the Company to pay damage awards or settlements (or become subject to equitable remedies) that could have a material adverse effect on the Company’s consolidated results of operations, balance sheet and/or operating cash flows in the periods recognized or paid.

We assumed from Honeywell International Inc. ("Honeywell") all health, safety and environmental (“HSE”) liabilities and compliance obligations related to the past and future operations of our current business, as well as all HSE liabilities associated with the three manufacturing locations assumed from Honeywell that are used in our current operations, including any cleanup or other liabilities related to any contamination that may have occurred at such locations in the past. Honeywell retained all HSE liabilities related to former business locations or the operation of our former businesses. Although we have ongoing environmental remedial obligations at certain of our facilities, in the past three years, the associated remediation costs have not been material, and we do not expect our known remediation costs to have a material adverse effect on the Company's consolidated financial position or results of operations.

10. Income Taxes

The provision (benefit) for income taxes was ($0.9 million) and $7.5 million for the three months ended September 30, 2025 and 2024, respectively, resulting in an effective tax rate of 25.6% and 25.1%, respectively. The provision for income taxes was $5.0 million and $14.6 million for the nine months ended September 30, 2025 and 2024, respectively, resulting in an effective tax rate of 8.7% and 25%, respectively.

The Company’s provision (benefit) for income taxes in interim periods is computed by applying an estimated annual effective tax rate against Income (loss) before taxes for the period in addition to recording any tax effects of discrete items for the quarter. The Company’s effective tax rate for the three and nine months ended September 30, 2025 and 2024 differed from the U.S. federal statutory rate due to state taxes and executive compensation deduction limitations which generally increase the rate, offset by research tax credits and the foreign-derived intangible income deduction that generally decrease the rate. During the nine months ended September 30, 2025, discrete tax adjustments recorded relating to Internal Revenue Code (IRC) Section 45Q tax credits of $9.7 million and return to provision adjustments related to the filing of the Company's 2024 U.S. federal income tax return of $0.2 million, offset slightly by state tax legislation changes and the vesting of equity compensation, resulted in a net 5% increase and 17% decrease to the estimated annual effective tax rate for the three and nine months ended

(Dollars in thousands, except share and per share amounts and as otherwise noted)

September 30, 2025, respectively. In 2024, the Company recorded discrete tax adjustments related to the vesting of equity compensation, changes to state tax legislation, and return to provision adjustments related to the filing of the Company's 2023 U.S. federal income tax return which resulted in a net 3.3% and 1.5% increase to the estimated annual effective tax rate for the three and nine months ended September 30, 2024, respectively.

On July 4, 2025, President Trump signed into law legislation commonly referred to as the One Big Beautiful Bill Act (the "Act"), which includes numerous tax provisions affecting businesses, including the reinstatement of full expensing of domestic research and experimental expenditures, modification of the limitation on business interest and making permanent full expensing for certain business property. These provisions resulted in an approximate $10 million reduction in cash taxes in our financial results for the three and nine months ended September 30, 2025, however due to the elective applicability of these provisions, we continue to evaluate the full impact and timing that these provisions will have on our financial results.

11. Supplier Finance Programs

The Company has entered into a supply chain finance program with a financial intermediary providing participating suppliers the option to be paid by the intermediary earlier than the original invoice due date. AdvanSix’s responsibility is limited to making payments to the intermediary based upon payment terms negotiated with the suppliers, regardless of whether the intermediary pays the supplier in advance of the original due date. The Company’s payment terms with suppliers are consistent, regardless of whether a vendor participates in the supply chain finance program or not. All related agreements are terminable by either party upon at least 30 days’ notice.

The total amount due to the financial intermediary to settle supplier invoices under the Company's supply chain finance program was approximately $5.8 million as of September 30, 2025 and approximately $19.2 million as of December 31, 2024. These amounts outstanding are included in Accounts payable.

12. Segment Related Information

The Company has concluded that it is a single operating segment and a single reportable segment: chemical manufacturing. Its larger manufacturing sites are vertically integrated and leverage cross-plant resources, including centralized supply chain and procurement functions. This production process uses one key raw material, cumene, as the input to products produced for sale through the sales channels and end markets the Company serves. Production rates and output volumes are managed across locations to align with the Company’s overall operating plan. Additionally, the Company’s operating results, which are evaluated regularly to make decisions about resource allocation and performance assessment by the chief operating decision maker ("CODM"), our CEO and President, are on a consolidated basis.

The chemical manufacturing segment derives its revenues by innovating and delivering essential products in the industries of nylon solutions, plant nutrients, and chemical intermediates to its customers in a wide variety of end markets and applications, such as building and construction, fertilizers, agrochemicals, plastics, solvents, packaging, paints, coatings, adhesives and electronics.

The CODM’s performance assessment and resource allocation for the chemical manufacturing segment is based on net income which is also reported on the income statement as net income, the measure of segment assets which is also reported on the balance sheet as total assets, and capital expenditures which is also reported in management’s discussion and analysis.

The CODM uses net income generated from segment assets in deciding whether to reinvest profits into the segment or into other parts of the entity, such as for acquisitions or to pay dividends. The CODM also uses net income to monitor budget versus actual results. Monitoring budgeted versus actual results is used in assessing performance of the segment and in establishing management’s compensation. Lastly, the CODM uses capital expenditures to estimate the cash-generating potential and cash requirements of the segment.

Significant expense information reviewed by the CODM was as follows (in thousands):

Business Overview

AdvanSix is a diversified chemistry company that produces essential materials for our customers in a wide variety of end markets and applications that touch people’s lives. Our integrated value chain of our five U.S.-based manufacturing facilities plays a critical role in global supply chains and enables us to innovate and deliver essential products for our customers across

building and construction, fertilizers, agrochemicals, plastics, solvents, packaging, paints, coatings, adhesives, electronics and other end markets. Guided by our core values of Safety, Integrity, Accountability and Respect, AdvanSix strives to deliver best-in-class customer experiences and differentiated products in the industries of nylon solutions, plant nutrients, and chemical intermediates. Our key product lines are as follows:

•Nylon Solutions

◦Nylon – We sell our Nylon 6 resin globally, primarily under the Aegis® brand name. Nylon 6 is a polymer resin which is a synthetic material used by our customers to produce fibers, filaments, engineered plastics and films that, in turn, are used in such end-products as carpets, automotive and electric components, sports apparel, food packaging and other industrial applications.

◦Caprolactam – Caprolactam is the key monomer used in the production of Nylon 6 resin. We internally polymerize caprolactam into Aegis® Nylon 6 Resins, and we also market and sell the caprolactam that is not consumed internally to customers who use it to manufacture polymer resins to produce fibers, compounds and other nylon products. Our Hopewell, VA manufacturing facility is one of the world’s largest single-site producers of caprolactam as of September 30, 2025.

•Plant Nutrients – Our ammonium sulfate is used by customers as a fertilizer containing nitrogen and sulfur, two key plant nutrients. Ammonium sulfate fertilizer is derived from the integrated operations at the Hopewell manufacturing facility. Because of our Hopewell facility’s size, scale and technology design, we are the world’s largest single-site producer of ammonium sulfate fertilizer as of September 30, 2025. We market and sell ammonium sulfate primarily to North American and South American distributors, farm cooperatives and retailers to fertilize crops. We also manufacture sulfuric acid, ammonia and carbon dioxide as part of our integrated operations at Hopewell and occasionally sell any excess material not consumed internally to customers externally.

•Chemical Intermediates – We manufacture, market and sell a number of chemical intermediate products that are derived from the manufacturing processes within our integrated supply chain. Most significant is acetone which is used by our customers in the production of solvents, paints, coatings, adhesives, resins and herbicides. Other intermediate chemicals that we manufacture, market and sell include phenol, alpha-methylstyrene, cyclohexanone, oximes, cyclohexanol, and alkyl and specialty amines. Additional end-products for intermediates include automotive components, and water treatment and pharmaceutical intermediates.

Global demand for Nylon 6 resin spans a variety of end-uses such as textiles, engineered plastics, industrial filament, food and industrial films, and carpet. The market growth typically tracks global GDP growth over the long-term but varies by end-use. We produce and sell caprolactam as a commodity product and produce and sell our Nylon 6 resin as both a commoditized and differentiated resin product. Our results of operations are primarily driven by production volume and the spread between the sales prices of our products and the costs of the underlying raw materials built into market-based and value-based pricing models. The global prices for nylon resin typically track a spread over the price of caprolactam, which in turn tracks as a spread over benzene because the key feedstock materials for caprolactam, phenol or cyclohexane, are derived from benzene. This price spread has historically experienced cyclicality as a result of global changes in supply and demand. Generally, Nylon 6 resin prices track the cyclicality of caprolactam prices, although prices set above the spread are achievable when nylon resin manufacturers, like AdvanSix, formulate and produce differentiated nylon resin products for current and new customer applications, such as our wire and cable and co-polymer offerings.

Global prices for ammonium sulfate fertilizer are influenced by several factors including the price of urea, which is the most widely used source of nitrogen-based fertilizer in the world. Other global factors driving ammonium sulfate fertilizer demand are general agriculture trends, including planted acres and the price of crops. Our ammonium sulfate product is positioned with the added value proposition of sulfur nutrition to increase yields of key crops. In addition, due to its nutrient density, the typical ammonium sulfate product delivers pound for pound the most readily available sulfur and nitrogen to crops as compared to other fertilizers. We also directly supply packaged ammonium sulfate to customers, primarily in North and South America, and have diversified and optimized our offerings to include spray-grade adjuvants to support crop protection, as well as other specialty fertilizers and products for industrial use.

Our ammonium sulfate fertilizer experiences quarterly sales seasonality reflecting both geographical and product sales mix considerations based on the timing and length of the growing seasons in North and South America. The North American fertilizer season typically runs from July, when the value chain begins restocking fertilizer, through June of the following year, when most application for the year’s planting is completed. The new season fill begins in the third quarter and proceeds sequentially into the following spring, which is the peak period for crop fertilizer application. As a result of this pattern, North American ammonium sulfate demand and pricing, particularly for our higher-value granular product, are typically strongest in

the first half of the year through application for the spring crop and then decline in the second half of the year. Ammonium sulfate industry prices in the corn belt have declined approximately 12% from the second quarter to the third quarter, on average, since 2016. Due to the ammonium sulfate fertilizer sales cycle, we occasionally build up higher inventory balances because our production is continuous throughout the year and not tied to seasonal demand for fertilizers. Sales of most of our other products have generally been subject to minimal, or no, seasonality.

We also manufacture, market and sell a number of chemical intermediate products that are derived from the manufacturing processes within our integrated supply chain. Most significant is acetone, the price of which is influenced by its own supply and demand dynamics but can also be influenced by the underlying move in propylene input costs. Our differentiated product offerings include high-purity applications and high-value intermediates including our U.S. Amines portfolio as well as our oximes-based EZ-Blox™ anti-skinning agent used in paints and Nadone® cyclohexanone, which is a solvent used in various high-value applications.

We seek to run our production facilities on a nearly continuous basis for maximum efficiency as several of our intermediate products are key feedstock materials for other products in our integrated manufacturing chain. While our integration, scale and range of product offerings make us one of the most efficient manufacturers in our industry, these attributes also expose us to increased risk associated with material disruptions at any one of our production facilities or logistics operations which could impact the overall manufacturing supply chain. Further, although we believe that our sources of supply for our raw materials, including cumene, natural gas and sulfur, are generally robust, it is difficult to predict the impact that shortages, increased costs and related supply chain logistics considerations may have in the future. In order to mitigate the risk of unplanned interruptions, we schedule planned plant turnarounds each year to conduct routine and major maintenance across our facilities. We also utilize maintenance excellence and mechanical integrity programs, targeted buffer inventory of intermediate chemicals necessary for our manufacturing process, and co-producer swap arrangements, which are intended to mitigate the extent of any production losses as a result of planned and unplanned downtime; however, the mitigation of all or part of any such production impact cannot be assured.

Recent Developments

Amendment to Credit Agreement

On October 23, 2025, the Company entered into Amendment No. 2 (the “Amendment”) to the Credit Agreement (as defined below). See “Liquidity and Capital Resources - Credit Agreement” for a discussion regarding the Amendment.

Anti-Dumping Duty Petition - Acetone

On November 4, 2024, the U.S. Department of Commerce ("Commerce") initiated the first five-year review of the anti-dumping orders on imports of acetone from Belgium, Singapore, South Africa, South Korea, and Spain. On November 1, 2024, the U.S. International Trade Commission ("ITC") issued its notice of initiation of its five-year review of the orders. The anti-dumping orders and applicable duties will continue for another five-year period if Commerce finds that revocation of the orders is likely to lead to continuation or recurrence of dumping and if the ITC finds that revocation is likely to lead to continuation or recurrence of material injury to the U.S. domestic industry. On December 26, 2024, Commerce notified the ITC that it would conduct an expedited review and issue its results no later than March 4, 2025. On February 4, 2025, the ITC voted to conduct a full review and is expected to issue its results in the fourth quarter of 2025. On March 7, 2025, Commerce determined that revocation of the anti-dumping orders would likely lead to continuation of recurrence of dumping. The anti-dumping duties will continue to apply during the ITC's pending review.

Philadelphia Energy Solutions’ Shut Down

The Company previously reported a business impact associated with the June 2019 fire that shut down the Philadelphia Energy Solutions (“PES”) refinery in Philadelphia, Pennsylvania. PES was one of multiple suppliers to the Company of cumene, a feedstock material used to produce phenol, acetone and other chemical intermediates. The Company has been actively pursuing the claim over several years, with a final omnibus settlement in January 2025 which resulted in insurance settlement proceeds of approximately $26 million in the first quarter of 2025. The total aggregate insurance proceeds since the original claim submission are approximately $39 million.

The change in sales compared to the prior year period is attributable to the following:


	Three Months Ended September 30, 2025	Nine Months Ended September 30, 2025
Volume	(3.2)%	(1.9)%
Price	(2.8)%	(0.3)%

	(6.0)%	(2.2)%

Sales decreased in the three months ended September 30, 2025 compared to the prior year period by $23.7 million (approximately 6%) due to (i) lower raw material pass through pricing (approximately 5%) following a net cost decrease in benzene and propylene (inputs to cumene which is a key feedstock to our products) and (ii) decreased volume (approximately 3%) primarily driven by softer demand in chemical intermediate and nylon end markets, partially offset by favorable market-based pricing (approximately 2%) driven by continued strength in Plant Nutrients reflecting favorable North American ammonium sulfate supply and demand conditions.

Sales decreased in the nine months ended September 30, 2025 compared to the prior year period by $26.2 million (approximately 2%) due to decreased volume (approximately 2%) driven by softer demand in nylon end markets partially offset by higher granular ammonium sulfate sales supported by our SUSTAIN (Sustainable U.S. Sulfate to Accelerate Increased Nutrition) program. Pricing was flat, primarily reflecting favorable market-based pricing across our Plant Nutrients and Nylon Solutions product lines offset by lower raw material pass through pricing following a net cost decrease in benzene and propylene.

Costs of Goods Sold


	Three Months Ended September 30,				Nine Months Ended September 30,
	2025		2024		2025		2024
Costs of goods sold	$	349,088	$	340,885	$	1,024,716	$	1,046,860
% change compared with prior year period	2.4%				(2.1)%
Gross Margin percentage	6.8%		14.4%		11.8%		11.9%

Costs of goods sold increased in the three months ended September 30, 2025 compared to the prior year period by $8.2 million (approximately 2%) due to (i) increased plant costs (approximately 2%) driven primarily by utility costs and (ii) increased raw material costs (approximately 1%) driven by sulfur and natural gas.

Costs of goods sold decreased in the nine months ended September 30, 2025 compared to the prior year period by $22.1 million (approximately 2%) due to (i) insurance proceeds collected as a result of the PES supplier shutdown (approximately 3%),and (ii) decreased sales volume (approximately 3%), partially offset by (i) increased raw material costs (approximately 2%) driven by sulfur and natural gas and (ii) increased plant costs driven primarily by utility costs (approximately 1%).

Gross margin percentage decreased in the three months ended September 30, 2025 compared to the prior year period (approximately 8%) due primarily to (i) the impact of pricing, net of raw material costs (approximately 3%), (ii) increased plant costs driven primarily by utility costs (approximately 2%), and (iii) lower sales volumes as discussed above (approximately 2%).

Gross margin percentage was approximately flat in the nine months ended September 30, 2025 compared to the prior year period due to insurance proceeds collected as a result of the PES supplier shutdown (approximately 2%), offset by the impact of pricing, net of raw material costs (approximately 2%).

Selling, General and Administrative Expenses


	Three Months Ended September 30,				Nine Months Ended September 30,
	2025		2024		2025		2024
Selling, general and administrative expenses	$	27,425	$	24,265	$	76,250	$	72,290
Percentage of Sales	7.3%		6.1%		6.6%		6.1%

Selling, general and administrative expenses increased by $3.2 million in the three months ended September 30, 2025 compared to the prior year period due primarily to legal and professional fees associated with strategic regulatory matters and potential inorganic growth options, and the planned investment to upgrade our enterprise resource planning system.

Selling, general and administrative expenses increased by $4.0 million in the nine months ended September 30, 2025 compared to the prior period due primarily to legal and professional fees associated with strategic regulatory matters and potential inorganic growth options, and the planned investment to upgrade our enterprise resource planning system.

Income Tax Expense (Benefit)


	Three Months Ended September 30,				Nine Months Ended September 30,
	2025		2024		2025		2024
Income tax expense (benefit)	$	(909)	$	7,479	$	4,955	$	14,603
Effective tax rate	25.6%		25.1%		8.7%		25.0%

The Company’s provision (benefit) for income taxes in interim periods is computed by applying an estimated annual effective tax rate against Income (loss) before taxes for the period in addition to recording any tax effects of discrete items for the quarter. The Company’s effective tax rate for the three and nine months ended September 30, 2025 and 2024 differed from the U.S. federal statutory rate due to state taxes and executive compensation deduction limitations which generally increase the rate, offset by research tax credits and the foreign-derived intangible income deduction that generally decrease the rate. During the nine months ended September 30, 2025, discrete tax adjustments recorded relating to Internal Revenue Code (IRC) Section 45Q tax credits of $9.7 million and return to provision adjustments related to the filing of the Company's 2024 U.S. federal income tax return of $0.2 million, offset slightly by state tax legislation changes and the vesting of equity compensation, resulted in a net 5% increase and 17% decrease in the estimated annual effective tax rate for the three and nine months ended September 30, 2025, respectively. In 2024, the Company recorded discrete tax adjustments related to the vesting of equity compensation, changes to state tax legislation, and return to provision adjustments related to the filing of the Company's 2023 U.S. federal income tax return which resulted in a net 3.3% and 1.5% increase to the estimated annual effective tax rate for the three and nine months ended September 30, 2024, respectively.

The Company’s effective tax rate for the three months ended September 30, 2025 was marginally higher than the prior year period. The increase was mainly attributed to the effect of return-to-provision adjustments on the tax rate during the three months ended September 30, 2025, relative to the prior year period, partially offset by a reduction in state taxes during the three months ended September 30, 2025 relative to the prior year period.

The Company’s effective tax rate for the nine months ended September 30, 2025 was lower than the prior year period due primarily to the impact of the IRC Section 45Q tax credits recorded in the current year-to-date period compared to the prior year-to-date period.

On July 4, 2025, President Trump signed into law legislation commonly referred to as the One Big Beautiful Bill Act (the "Act"), which includes numerous tax provisions affecting businesses, including the reinstatement of full expensing of domestic research and experimental expenditures, modification of the limitation on business interest and making permanent full expensing for certain business property. These provisions resulted in an approximate $10 million reduction in cash taxes in our financial results for the three and nine months ended September 30, 2025 and we anticipate that it will also reduce our cash taxes in future periods. However, due to the elective applicability of these provisions, we are still evaluating the full impact and timing that these provisions will have on our financial results. We do not currently anticipate that the Act will have a material impact on our effective tax rate.

Net Income


	Three Months Ended September 30,				Nine Months Ended September 30,
	2025		2024		2025		2024
Net income (loss)	$	(2,638)	$	22,266	$	52,077	$	43,797

As a result of the factors described above, Net income (loss) was ($2.6) million and $52.1 million for the three and nine months ended September 30, 2025, respectively, as compared to $22.3 million and $43.8 million in the corresponding prior year period.

Non-GAAP Measures

(Dollars in thousands, unless otherwise noted)

The following tables set forth the non-GAAP financial measures of Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net income and Adjusted EPS. Adjusted EBITDA is defined as Net income before Interest, Income taxes, Depreciation and amortization, Non-cash stock-based compensation, Non-recurring, unusual or extraordinary expenses, Non-cash amortization from acquisitions and One-time merger and acquisition costs. Adjusted EBITDA Margin is equal to Adjusted EBITDA divided by Sales. The Company believes these non-GAAP financial measures provide meaningful supplemental information as they are used by the Company’s management to evaluate the Company’s operating performance, enhance a reader’s understanding of the financial performance of the Company, and facilitate a better comparison among fiscal periods and performance relative to its competitors, as the non-GAAP measures exclude items that management believes do not reflect the Company’s ongoing operations.

These non-GAAP results are presented for supplemental informational purposes only and should not be considered a substitute for the financial information presented in accordance with U.S. GAAP. Non-GAAP financial measures should be read only in conjunction with the comparable U.S. GAAP financial measures. The Company's non-GAAP measures may not be comparable to other companies' non-GAAP measures.

The following is a reconciliation between the non-GAAP financial measures of Adjusted Net income, Adjusted EBITDA and Adjusted EBITDA Margin to their most directly comparable U.S. GAAP financial measure:

Liquidity and Capital Resources

(Dollars in thousands, unless otherwise noted)

Liquidity

We believe that cash balances and operating cash flows, together with available capacity under our credit agreement, as utilized in the third quarter of 2025, will provide adequate funds to support our current short-term operating objectives as well as our longer-term strategic plans, subject to the risks and uncertainties outlined below, in our "Note Regarding Forward-Looking Statements" above, and in the risk factors previously disclosed in Item 1A of Part I of our 2024 Form 10-K. Our principal source of liquidity is our cash flow generated from operating activities, which is expected to provide us with the ability to meet the majority of our short-term funding requirements for the next twelve months and beyond. Our cash flows are affected by capital requirements and production volume, which may be materially impacted by unanticipated events such as unplanned downtime, material disruptions at our production facilities, the prices of our raw materials, general economic and industry trends and customer demand. The Company applies a proactive and disciplined approach to working capital management to optimize cash flow and to enable capital allocation options in support of the Company’s strategy. We utilize supply chain financing and trade receivables discount arrangements with third-party financial institutions which optimize terms and conditions related to accounts receivable and accounts payable in order to enhance liquidity and enable us to efficiently manage our working capital needs. Although we continue to optimize supply chain financing and trade receivable programs in the ordinary course, our utilization of these arrangements has not had a material impact on our liquidity. In addition, we monitor the third-party depository institutions that hold our cash and cash equivalents. Our emphasis is primarily on the safety of principal and secondarily on maximizing yield on those funds. We diversify our cash and cash equivalents among counterparties to minimize exposure to any one of these entities.

On a recurring basis, our primary future cash needs will be centered on operating activities, working capital, capital expenditures, dividends and liquidity reflecting disciplined capital deployment. Capital expenditures are deployed for various ongoing investments and initiatives to improve reliability, yield and quality, expand production capacity and comply with health, safety and environmental ("HSE") regulations. We believe that our future cash from operations, cash on hand and available capacity under our credit agreement, as well as our access to credit and capital markets, will provide adequate resources to fund our expected operating and financing needs and obligations. Our ability to fund our capital needs, however, will depend on our ongoing ability to generate cash from operations and access to credit and capital markets, both of which are subject to the risk factors previously disclosed in Item 1A of Part I of our 2024 Form 10-K, as well as general economic, financial, competitive, regulatory and other factors that are beyond our control.

As of the end of the third quarter of 2025, the Company had approximately $23.7 million of cash on hand with approximately $249 million of additional capacity available under the revolving credit facility. The Company’s Consolidated Leverage Ratio financial covenant of its credit facility allows it to net up to $75 million of cash with debt. Capital expenditures are expected to

be approximately $120 million to $125 million in 2025 compared to $134 million in 2024, reflecting the planned progression of our SUSTAIN growth program, and refined execution timing to address critical enterprise risk mitigation.

We assumed from Honeywell International Inc. ("Honeywell") all HSE liabilities and compliance obligations related to the past and future operations of our current business as of the spin-off, as well as all HSE liabilities associated with the three manufacturing locations assumed from Honeywell that are used in our current operations, including any cleanup or other liabilities related to any contamination that may have occurred at such locations in the past. Honeywell retained all HSE liabilities related to former business locations or the operation of our former businesses. Although we have ongoing environmental remedial obligations at certain of our facilities, in the past three years, the associated remediation costs have not been material, and we do not expect our known remediation costs to have a material adverse effect on the Company's consolidated financial position or results of operations.

We expect that our primary cash requirements for 2025 will be to fund costs associated with ongoing operations, capital expenditures, and amounts related to other contractual obligations.

The Company made no cash contributions to the defined benefit pension plan during the nine months ended September 30, 2025 as there were no funding requirements for the period. Additional contributions may be made in future periods sufficient to satisfy pension funding requirements in those periods or on a discretionary basis.

As of September 30, 2025, the Company has repurchased a total of 6,313,789 shares of common stock life-to-date, including 1,068,333 shares withheld to cover tax withholding obligations in connection with the vesting of awards, for an aggregate of $194.1 million at a weighted average market price of $30.74 per share. As of September 30, 2025, approximately $62.0 million remained available for share repurchases under the current authorization approved by the Board on February 17, 2023. During the period October 1, 2025 through October 31, 2025, no additional shares were repurchased for tax withholding obligations or under the currently authorized repurchase program.

Repurchases may be made from time to time on the open market in accordance with Rule 10b-18 of the Exchange Act, including through the use of trading plans intended to qualify under Rule 10b5-1 of the Exchange Act. The size and timing of these repurchases will depend on pricing, market and economic conditions, legal and contractual requirements and other factors. The share repurchase program has no expiration date and may be modified, suspended or discontinued at any time. The par value of the shares repurchased is applied to Treasury stock and the excess of the purchase price over par value is applied to Additional paid-in capital.

As of September 30, 2025, the Company did not have any off-balance sheet arrangements as described in Instruction 8 to Item 303(b) of Regulation S-K and did not have any material changes in the commitments or contractual obligations detailed in the 2024 Form 10-K (see Part II, Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" under "Liquidity and Capital Resources - Liquidity"). The Company has not guaranteed any debt or commitments of other entities or entered into any options on non-financial assets.

The timing, declaration, amount and payment of future dividends to stockholders, if any, will fall within the discretion of our Board. Holders of shares of our common stock will be entitled to receive dividends when, and if, declared by our Board at its discretion out of funds legally available for that purpose, subject to the terms of our indebtedness, the preferential rights of any preferred stock that may be outstanding, legal requirements, regulatory constraints, industry practice and other factors that our Board deems relevant.

Credit Agreement

On October 27, 2021, the Company entered into a Credit Agreement, as amended on June 27, 2023 (the “Credit Agreement”), among the Company, the lenders party thereto, the swing line lenders party thereto, the letter of credit issuers party thereto and Truist Bank, as administrative agent, which provides for a senior secured revolving credit facility in an aggregate principal amount of $500 million (the “Revolving Credit Facility”).

Borrowings under the Revolving Credit Facility are subject to customary borrowing conditions.

The Revolving Credit Facility provided for a scheduled maturity date of October 27, 2026. The Credit Agreement permits the Company to utilize up to $40 million of the Revolving Credit Facility for the issuance of letters of credit and up to $40 million for swing line loans. The Company has the option to establish a new class of term loans and/or increase the amount of the Revolving Credit Facility in an aggregate principal amount for all such incremental term loans and increases of the Revolving Credit Facility of up to the sum of (x) $175 million plus (y) an amount such that the Company’s Consolidated First Lien Secured Leverage Ratio (as defined in the Credit Agreement) would not be greater than 2.75 to 1.00, in each case, to the extent that any one or more lenders, whether or not currently party to the Credit Agreement, commits to be a lender for such amount or any portion thereof.

Borrowings under the Credit Agreement bear interest at a rate equal to either the sum of a base rate plus a margin ranging from 0.25% to 1.25% or the sum of an Adjusted Term SOFR rate plus a margin ranging from 1.25% to 2.25%, with either such margin varying according to the Company’s Consolidated Leverage Ratio (as defined in the Credit Agreement). The Company is also required to pay a commitment fee in respect of unused commitments under the Revolving Credit Facility, if any, at a rate ranging from 0.15% to 0.35% per annum depending on the Company’s Consolidated Leverage Ratio.

Substantially all tangible and intangible assets of the Company and its domestic subsidiaries are pledged as collateral to secure the Company's obligations under the Credit Agreement.

The Credit Agreement contains customary covenants limiting the ability of the Company and its subsidiaries to, among other things, pay cash dividends, incur debt or liens, redeem or repurchase stock of the Company, enter into transactions with affiliates, make investments, make capital expenditures, merge or consolidate with others or dispose of assets. The Credit Agreement also contains financial covenants that require the Company to maintain a Consolidated Interest Coverage Ratio (as defined in the Credit Agreement) of not less than 3.00 to 1.00 and to maintain a Consolidated Leverage Ratio of (ii) 3.75 to 1.00 or less (subject to the Company’s option to elect a consolidated leverage ratio increase in connection with certain acquisitions). If the Company does not comply with the covenants in the Credit Agreement, the lenders may, subject to customary cure rights, require the immediate payment of all amounts outstanding under the Revolving Credit Facility. We were in compliance with all of our covenants at September 30, 2025 and through the date of the filing of this Form 10-Q.

We had a borrowed balance of $195 million under the Revolving Credit Facility at December 31, 2024. We borrowed an incremental net amount of $55 million during the nine months ended September 30, 2025, bringing the balance under the Revolving Credit Facility to $250 million, and available credit for use of approximately $249 million as of September 30, 2025. We expect that Cash provided by operating activities will fund future interest payments on the Company's outstanding indebtedness.

On October 23, 2025, the Company entered into Amendment No. 2 (the “Amendment”) to the Credit Agreement, (as further amended by the Amendment, the “Amended Credit Agreement”), among the Company, the guarantors, the lenders party thereto and Truist Bank, as administrative agent.

The Credit Agreement includes a senior secured revolving credit facility with aggregate commitments of $500 million (the “Revolving Credit Commitments”). Pursuant to the Amendment, the Credit Agreement was amended to, among other things: (i) extend the maturity date of revolving credit commitments of participating Revolving Credit Lenders, as defined in the Amended Credit Agreement, in an aggregate principal amount of $452 million to the earlier of (x) October 27, 2027 and (y) the date of the termination in whole of the Revolving Credit Commitments, pursuant to the terms of the Amended Credit Agreement, and (ii) effect certain other conforming changes and modifications consistent with the foregoing. The remaining $48 million of revolving credit commitments under the Credit Agreement that were not extended will continue to mature on the earlier of (x) October 27, 2026 and (y) the date of the termination in whole of the Revolving Credit Commitments, pursuant to the terms of the Amended Credit Agreement.

Cash Flow Summary


	Nine Months Ended September 30,
	2025		2024
Cash provided by (used for):
Operating activities	$	59,141	$	71,248
Investing activities	(95,002)		(105,426)
Financing activities	39,993		21,708
Net change in cash and cash equivalents	$	4,132	$	(12,470)

Cash provided by operating activities decreased by $12.1 million for the nine months ended September 30, 2025 versus the prior year period due primarily to (i) the unfavorable cash impact of $17.7 million from Taxes receivable and Income taxes payable combined, driven by the timing of tax receipts and (ii) a $11.6 million unfavorable cash impact from working capital (comprised of Accounts and other receivables, Inventories, Accounts payable and Deferred income and customer advances) with $56.0 million unfavorable cash impact from working capital for the nine months ended September 30, 2025 compared to a $44.4 million unfavorable cash impact in the prior year period. These net unfavorable impacts were partially offset by (i) a favorable impact of $10.8 million from Deferred income taxes and (ii) an $8.3 million increase in Net income.

Cash used for investing activities decreased by $10.4 million for the nine months ended September 30, 2025 versus the prior year period due primarily to the timing of cash payments for capital expenditures and other enterprise programs.

Cash provided by financing activities increased by $18.3 million for the nine months ended September 30, 2025 versus the prior year period due primarily to (i) net borrowings of $55.0 million during the nine months ended September 30, 2025 compared to net borrowings of $45.0 million during the prior year period and (ii) payments for share repurchases of $1.7 million during the nine months ended September 30, 2025 compared to $10.4 million during the prior year period.

Capital Expenditures

(Dollars in thousands, unless otherwise noted)

Our operations are capital intensive, requiring ongoing investments that have consisted, and are expected to continue to consist, primarily of capital expenditures required to maintain and improve equipment reliability, expand production output, further improve mix, yield and cost position, and comply with environmental and safety regulations.

The following table summarizes ongoing and expansion capital expenditures:


	Nine Months Ended September 30, 2025
Capital expenditures in Accounts payable at December 31, 2024	$	23,645
Purchases of property, plant and equipment	80,098
Less: Capital expenditures in Accounts payable at September 30, 2025	(14,894)
Cash paid for capital expenditures	$	88,849

For 2025, we expect our total capital expenditures to be approximately $120 million to $125 million as discussed above.

Critical Accounting Policies and Estimates

The preparation of our Condensed Consolidated Financial Statements in accordance with U.S. GAAP is based on the selection and application of accounting policies that require us to make significant estimates and assumptions about the effects of matters that are inherently uncertain. We consider these accounting policies to be critical to the understanding of our Condensed Consolidated Financial Statements. For a full description of our critical accounting policies, refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our 2024 Form 10-K. While there have been no material changes to our critical accounting policies, or the methodologies or assumptions we apply under them since the filing of the 2024 Form 10-K, we continue to monitor such methodologies and assumptions.

Recent Accounting Pronouncements

See “Note 2. Recent Accounting Pronouncements” to the Condensed Consolidated Financial Statements included in Part I. Item 1 of this Form 10-Q.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our exposure to risk based on changes in interest rates during the nine-month period ended September 30, 2025 relates primarily to the Revolving Credit Facility. The Revolving Credit Facility bears interest at floating rates. For variable rate debt, interest rate changes generally do not affect the fair market value of such debt assuming all other factors remain constant but do impact future earnings and cash flows. Accordingly, we may be exposed to interest rate risk on borrowings under the Credit Agreement.

Based on current borrowing levels at September 30, 2025, a 25-basis point fluctuation in interest rates for the nine months ended September 30, 2025 would have resulted in an increase or decrease to our interest expense of approximately $0.6 million.

See “Note 2. Summary of Significant Accounting Policies” to the Consolidated Financial Statements included in Item 8 of our 2024 Form 10-K for a discussion relating to credit and market, commodity price and interest rate risk management.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to management, including the Chief Executive Officer and Interim Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives. Because there are inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud have been, or will be, detected.

Our Chief Executive Officer and Interim Chief Financial Officer, with the assistance of other members of our management, conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this quarterly report. Based upon such evaluation, our Chief Executive Officer and Interim Chief Financial Officer have concluded that our disclosure controls and procedures are effective at a reasonable assurance level as of September 30, 2025, the end of the period covered by this quarterly report.

Changes in Internal Control over Financial Reporting

Management has not identified any change in the Company's internal control over financial reporting that occurred during the quarter ended September 30, 2025 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

As previously reported, the Virginia Department of Environmental Quality ("VA DEQ") initiated discussions with the Company regarding certain alleged violations associated with air emissions and water discharges at the Company’s Hopewell facility. The Company entered into an Order by Consent with the VA DEQ in September 2025 in connection with the alleged water discharge violations of the State Water Control Law at the Company’s facility in Hopewell, Virginia, which provided for a civil charge of $55,841. The facility is continuing to assess and discuss the allegations associated with air emissions with the VA DEQ. Although the outcome of the matter cannot be predicted with certainty, we do not believe that it will have a material adverse effect on our consolidated financial position, results of operations or operating cash flows.

From time to time, we are involved in litigation relating to claims arising outside of the ordinary course of our business operations. We are not a party to, and, to our knowledge, there are no pending claims or actions against us, the ultimate disposition of which could be expected to have a material adverse effect on our consolidated financial position, results of operations or operating cash flows.
