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, 2024, and its results of operations for the three and nine months ended September 30, 2024 and 2023 and cash flows for the nine months ended September 30, 2024 and 2023. 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, 2023 (the "2023 Form 10-K"). 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, 2024 and 2023 were September 28, 2024 and September 30, 2023, respectively.

Liabilities to creditors to whom we have issued checks that remained outstanding at September 30, 2024 and December 31, 2023 aggregated to $2.4 million and $2.9 million, respectively, and were included in Cash and cash equivalents and Accounts payable in the Condensed Consolidated Balance Sheets.

The Company's Board of Directors (the "Board") has authorized share repurchase programs to repurchase shares of the Company's common stock as follows:

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.

As of September 30, 2024, the Company has repurchased a total of 6,252,129 shares of common stock, including 1,006,673 shares withheld to cover tax withholding obligations in connection with the vesting of awards, for an aggregate of $192.4 million at a weighted average market price of $30.78 per share. As of September 30, 2024, $62.0 million remained available for share repurchases under the current authorization. During the period October 1, 2024 through October 25, 2024, no additional shares were repurchased for tax withholding obligations or under the currently authorized repurchase program.

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.

On December 13, 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. The guidance is effective for public business entities for annual periods beginning after December 15, 2024. Early adoption of the amendments in this update are permitted for annual financial statements that have not yet been issued. 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 November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280). The amendments in this ASU require incremental disclosures about the Company's reportable segments, but do not change the definition of a segment or the guidance for determining reportable segments. The incremental disclosures should include (1) significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss, (2) an amount for other segment items by reportable segment and a description of its composition, (3) profit or loss and assets currently required by Topic 280 in interim periods, (4) clarification if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources and (5) the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The guidance is effective for public entities with fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. Additionally, public entities should apply the amendments retrospectively to all prior periods presented in the financial statements, unless impractical. 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.

3. Revenues

Revenue Recognition

AdvanSix serves around 400 customers annually, primarily in the United States, spanning a wide variety of industries worldwide. For each of the three months ended September 30, 2024 and 2023, the Company's ten largest customers accounted for approximately 41% of total sales. For the nine months ended September 30, 2024 and 2023, the Company's ten largest customers accounted for approximately 38% and 39% 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, 2024 and 2023 the Company's sales to Shaw were 10% and 12% of our total sales, respectively. For the nine months ended September 30, 2024 and 2023, the Company's sales to Shaw were 9% and 11% 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, 2024 and 2023 were as follows:

• The previously reported amounts have been corrected for a misclassification which overstated Ammonium Sulfate and understated Chemical Intermediates by $5.5 million (2%) and $26.6 million (2%) for the three and nine months ended September 30, 2023, respectively. Total revenue amounts were not impacted for either period.

The Company's revenues by geographic area, and related approximate percentage of total sales, for the three and nine months ended September 30, 2024 and 2023 were as follows:

Deferred Income and Customer Advances

The Company defers revenues when cash payments are received in advance of our performance. Below is a roll-forward of Deferred income and customer advances for the nine months ended September 30, 2024:

The Company expects to recognize as revenue the September 30, 2024 ending balance of Deferred income and customer advances within one year or less.

4. Earnings Per Share

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 diluted weighted average number of common shares outstanding, respectively. The details of the basic and diluted EPS calculationsfor thethree and nine months ended September 30, 2024 and 2023 were as follows:

Diluted EPS is computed based upon the weighted average number of common shares outstanding for the period plus the dilutive effect of common stock equivalents using the treasury stock method and the average market price of our common stock for the period.

The diluted EPS calculations exclude the effect of stock options when the options’ assumed proceeds exceed the average market price of the common shares during the period. The anti-dilutive common stock equivalents outstanding at the three and nine months ended September 30, 2024 and 2023 were as follows:

Dividend activity for the three and nine months ended September 30, 2024 and 2023 was as follows:

5. Accounts and Other Receivables–Net

6. Inventories

Substantially all of the Company’s inventories at September 30, 2024 and December 31, 2023 are valued at the lower of cost or market using the last-in, first-out (“LIFO”) method. However, approximately 8% was valued at average cost using the first-in, first-out (“FIFO”) method at September 30, 2024.

The excess of replacement cost over the carrying value of total inventories subject to LIFO was $65.1 million and $65.3 million at September 30, 2024 and December 31, 2023, respectively.

7. Leases

We determine if an arrangement is a lease at inception. Operating leases are included in Operating lease right-of-use assets ("ROU"), Operating lease liabilities – short-term, and Operating lease liabilities – long-term in our Condensed Consolidated Balance Sheets. Finance leases are included in Property, plant and equipment – net, Accounts payable, and Other liabilities in our Condensed Consolidated Balance Sheets.

The components of lease expense were as follows:

As of September 30, 2024, we have additional operating leases that have not yet commenced for approximately $93.1 million. These leases are expected to commence during the second half of 2024 and in 2025 with lease terms of up to 6 years.

8. Goodwill and Intangible Assets

Intangible assets with finite lives acquired through a business combination are recorded at fair value, less accumulated amortization. Customer relationships and trade-names are amortized on a straight-line basis over their expected useful lives of 15 to 20 years and 5 years, respectively.

Goodwill

There was no change in the carrying amount of goodwill for the nine months ended September 30, 2024.

Finite-Lived Intangible Assets

Intangible assets subject to amortization were as follows:

For each of the three months ended September 30, 2024 and September 30, 2023, the Company recorded amortization expense on intangible assets of $0.8 million. For each of the nine months ended September 30, 2024 and September 30, 2023, 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 of the spin-off, as well as all HSE liabilities associated with thethree 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 $7.5 million and ($2.1 million) for the three months ended September 30, 2024 and 2023, respectively, resulting in an effective tax rate of 25.1% and 20.7%, respectively. The provision for income taxes was $14.6 million and $17.8 million for the nine months ended September 30, 2024 and 2023, respectively, resulting in an effective tax rate of 25.0% and 22.9%, respectively.

The Company’s provision (benefit) for income taxes in interim periods is computed by applying an estimated annual effective tax rate against Income 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, 2024 and 2023 differed from the U.S. federal statutory rate, due primarily to the impacts of state taxes and executive compensation deduction limitations, offset by tax credits and the foreign-derived intangible income deduction. 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% increase to the quarterly effective tax rate and a net 1.5% increase to the year-to-date effective tax rate. Additionally for 2023, discrete tax adjustments relating to the vesting of equity compensation, changes in state tax legislation, and return to provision adjustments related to the filing of the Company's

2022 U.S. federal income tax return resulted in a net 4.4% increase to the quarterly effective tax rate and a net 1.6% decrease to the year-to-date effective tax rate.

11. Fair Value Measurements

Financial and non-financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The pension plan assets are invested in collective investment trust funds. These investments are measured at fair value using the net asset value per share as a practical expedient. Investments valued using the net asset value method (NAV) (or its equivalent) practical expedient are excluded from the fair value hierarchy disclosure.

The Company’s Condensed Consolidated Balance Sheets also include Cash and cash equivalents, Accounts receivable and Accounts payable all of which are recorded at amounts which approximate fair value.

The Company also has assets that are required to be recorded at fair value on a non-recurring basis. These assets are evaluated when certain triggering events occur (including a decrease in estimated future cash flows) that indicate the asset should be evaluated for impairment which could result in such assets being measured at fair value. Goodwill must be evaluated at least annually. Our annual evaluation occurred on October 28, 2023 and we concluded that an impairment for goodwill didnot occur.

12. 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 intermediaries to settle supplier invoices under the supplier finance programs was approximately $15 million as of September 30, 2024 and approximately $17 million as of December 31, 2023. These amounts outstanding are included in Accounts payable.

13. Subsequent Events

As announced on November 1, 2024, the Board declared a quarterly cash dividend of $0.16 per share on the Company's common stock, payable on November 26, 2024 to stockholders of record as of the close of business on November 12, 2024.
