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 playing a critical role in global supply chains, innovating and delivering essential products for our customers in a wide variety of end markets and applications that touch people’s lives, such as building and construction, fertilizers, agrochemicals, plastics, solvents, packaging, paints, coatings, adhesives and electronics. Our reliable and sustainable supply of quality products emerges from the integrated value chain of our five U.S.-based manufacturing facilities. AdvanSix strives to deliver best-in-class customer experiences and differentiated products in the industries of nylon solutions, chemical intermediates and plant nutrients, guided by our core values of Safety, Integrity, Accountability and Respect.

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, 2023, and its results of operations for the three and nine months ended September 30, 2023 and 2022 and cash flows for the nine months ended September 30, 2023 and 2022. 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, 2022 (the "2022 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, 2023 and 2022 were September 30, 2023 and October 1, 2022, respectively.

Liabilities to creditors to whom we have issued checks that remained outstanding at September 30, 2023 and December 31, 2022 aggregated to $5.0 million and $9.0 million, respectively, and were included in Cash and cash equivalents and Accounts payable in the Condensed Consolidated Balance Sheets.

The Company was party to three transactions during the third quarter of 2023: (i) exit from its alliance with Oben Holding Group S.A. resulting in a pre-tax gain of approximately $11.4 million, (ii) notification from a licensee of certain legacy ammonium sulfate technology assets operated at the licensee’s fertilizer manufacturing facility, that it intends to close its facility no later than August 2024, resulting in a non-cash, pre-tax charge of approximately $4.5 million and (iii) a strategic decision to exit production of certain low-margin oximes products resulting in a non-cash, pre-tax charge of approximately $2.4 million. Each of these transactions, totaling a net pre-tax gain of approximately $4.5 million, was recorded during the third quarter of 2023 and included as a component of Other non-operating (income) expense, net on the Condensed Consolidated Statements of Operations and a non-cash transaction on the Condensed Consolidated Statements of Cash Flows.

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

ADVANSIX INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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


Date of Authorization	Authorized Amount (millions)		Authorized Amount Remaining as of September 30, 2023 (millions)
May 4, 2018	$	75.0	$	—
February 22, 2019	75.0		1.6
February 17, 2023	75.0		75.0
Totals	$	225.0	$	76.6

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, 2023, the Company has repurchased a total of 5,541,948 shares of common stock, including 854,340 shares withheld to cover tax withholding obligations in connection with the vesting of awards, for an aggregate of $173.6 million at a weighted average market price of $31.33 per share. As of September 30, 2023, $76.6 million remained available for share repurchases under the current authorization. During the period October 1, 2023 through October 27, 2023, the Company repurchased an additional 101,387 shares at a weighted average market price of $29.07 per share primarily under the current 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.

In September 2022, the FASB issued ASU No. 2022-04, Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations. The amendments in this ASU require that a buyer in a supplier finance program disclose sufficient quantitative and qualitative information about its supplier finance programs to allow a user of the financial statements to understand the program’s nature, activity during the period, changes from period to period and potential magnitude. On a retrospective basis, for each annual reporting period, an entity should disclose the key terms of the program, including a description of the payment terms, assets pledged as security or other forms of guarantees, the confirmed amount outstanding that remains unpaid, a description of where the obligations are presented in the balance sheet and a roll-forward of those obligations confirmed as well as the amount of obligations subsequently paid. In each interim reporting period, an entity should disclose the amount of confirmed obligations outstanding. The guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on roll-forward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption of the amendments in this update is permitted. The Company adopted ASU 2022-04, effective January 1, 2023, which did not have a material impact on the Company's consolidated financial position or results of operations upon adoption.

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 calculations for the three and nine months ended September 30, 2023 and 2022 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, 2023 and 2022 were as follows:

However, approximately 9% was valued at average cost using the first-in, first-out (“FIFO”) method at September 30, 2023.

The excess of replacement cost over the carrying value of total inventories subject to LIFO was $61.4 million and $58.2 million at September 30, 2023 and December 31, 2022, 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:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022

As of September 30, 2023, we have additional operating leases that have not yet commenced for approximately $1.4 million. These leases will commence during December 2023 and January 2024 with lease terms of up to 7 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, 2023.

Finite-Lived Intangible Assets

Intangible assets subject to amortization were as follows:

For each of the three months ended September 30, 2023 and September 30, 2022, the Company recorded amortization expense on intangible assets of $0.8 million. For the nine months ended September 30, 2023 and September 30, 2022, the Company recorded amortization expense on intangible assets of $2.3 million and $2.0 million, respectively.

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 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 (benefit) provision for income taxes was ($2.1 million) and $2.7 million for the three months ended September 30, 2023 and 2022, respectively, resulting in an effective tax rate of 20.7% and 21.4%, respectively. The provision for income taxes was $17.8 million and $41.9 million for the nine months ended September 30, 2023 and 2022, respectively, resulting in an effective tax rate of 22.9% and 23.2%, respectively.

The Company’s provision 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, 2023 and 2022 differed from the U.S. federal statutory rate, due to the impacts of state taxes and executive compensation deduction limitations, offset by tax credits and the foreign-derived intangible income deduction. 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.

On August 16, 2022, the Inflation Reduction Act of 2022 (the "IRA") was signed into law. This legislation includes significant changes relating to tax, climate change, energy and health care. Among other provisions, the IRA introduces a corporate alternative minimum tax (CAMT) on adjusted financial statement income of certain large corporations and a 1% excise tax on share repurchases. The Company is not currently subject to the CAMT which became effective for tax years beginning after December 31, 2022. The 1% excise tax is generally applicable to publicly traded corporations for the net value of certain stock that the corporation repurchases during the year and is also effective for tax years beginning after December 31, 2022. The impact of any excise tax imposed on the Company for share repurchases is generally accounted for as an equity transaction with no consequences to the Company's results in operations, and this provision of the law is not expected to have a material impact on the Company's financial condition. The IRA also includes significant extensions, expansions and enhancements related to climate and energy tax credits designed to encourage investment in the adoption and expansion of renewable and alternative energy sources. The Company continues to evaluate these energy credit provisions of the law in relation to our sustainability and environmental, social and governance initiatives.

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. In July 2019, the Company entered into an interest rate swap transaction related to its credit agreement. The interest rate swap, considered a Level 2 liability, expired February 21, 2023.

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 March 31, 2023 and we concluded that an impairment for goodwill did not occur.

12. Derivative and Hedging Instruments

The specific credit and market, commodity price and interest rate risks to which the Company is exposed in connection with its ongoing business operations are described below. This discussion includes an explanation of any hedging instrument and interest rate swap agreement, used to manage the Company’s interest rate risk associated with a fixed and floating-rate borrowing.

For cash flow hedges, the entire change in the fair value of the hedging instrument included in the assessment of hedge effectiveness is recorded in Other comprehensive income. Those amounts are reclassified to earnings in the same income statement line item that is used to present the earnings effect of the hedged item when the hedged item affects earnings.

Credit and Market Risk – Financial instruments, including derivatives, expose the Company to counterparty credit risk for non-performance and to market risk related to changes in commodity prices, interest rates and foreign currency exchange rates. The Company manages its exposure to counterparty credit risk through specific minimum credit standards, diversification of counterparties, and procedures to monitor concentrations of credit risk. The Company’s counterparties in derivative transactions are substantial investment and commercial banks with significant experience using such derivative instruments. The Company monitors the impact of market risk on the fair value and cash flows of its derivative and other financial instruments considering reasonably possible changes in commodity prices, interest rates and foreign currency exchange rates and restricts the use of derivative financial instruments to hedging activities.

The Company continually monitors the creditworthiness of its customers to which it grants credit terms in the normal course of business. The terms and conditions of credit sales are designed to mitigate or eliminate concentrations of credit risk with any single customer. The Company did not have any customers with significant concentrations of trade accounts receivable – net at September 30, 2023 or December 31, 2022. Allowance for doubtful accounts is calculated based upon the Company's estimate of expected credit losses over the life of exposure based upon both historical information as well as future expected losses.

Commodity Price Risk Management – The Company's exposure to market risk for commodity prices can result in changes in the cost of production. We primarily mitigate our exposure to commodity price risk by using long-term, formula-based price contracts with our suppliers and formula-based price agreements with customers. Our customer agreements provide for price adjustments based on relevant market indices and raw material prices and generally do not include take-or-pay terms. We may also enter into forward commodity contracts with third-parties designated as hedges of anticipated purchases of several commodities. Forward commodity contracts are marked-to-market, with the resulting gains and losses recognized in earnings, in the same category as the items being hedged, when the hedged transaction is recognized. At September 30, 2023 and 2022, we had no financial contracts related to forward commodity agreements.

Interest Rate Risk Management – The Company had entered into one interest rate swap agreement for a total notional amount of $50 million to exchange floating for fixed rate interest payments for our LIBOR-based borrowings. The interest rate swap had a fair value of zero at inception and was effective July 31, 2019 and matured on February 21, 2023. In accordance with ASC 815, the Company designated the interest rate swap as a cash flow hedge of floating-rate borrowings. The interest rate swap converted the Company’s interest rate payments on the first $50 million of variable-rate, 1-month LIBOR-based debt to a fixed interest rate. The interest rate swap involved the receipt of floating rate amounts in exchange for fixed rate interest payments over the life of the interest rate swap without an exchange of the underlying principal amount.

In February 2022, the Company acquired the stock of U.S. Amines, a leading North American producer of alkyl and specialty amines serving high-value end markets such as agrochemicals and pharmaceuticals for a purchase price of approximately $97.5 million, net of cash acquired.

In January 2021, the Company acquired certain assets associated with ammonium sulfate packaging, warehousing and logistics services in Virginia from Commonwealth Industrial Services, Inc. ("CIS") for approximately $9.5 million.

14. 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 $17 million as of September 30, 2023 and December 31, 2022. These amounts outstanding are included in Accounts payable.

15. Subsequent Events

As announced on November 3, 2023, the Board declared a quarterly cash dividend of $0.160 per share on the Company's common stock, payable on November 28, 2023 to stockholders of record as of the close of business on November 14, 2023.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the Company’s financial condition and results of operations, which we refer to as our “MD&A,” should be read in conjunction with the Condensed Consolidated Financial Statements and the notes thereto contained in this Quarterly Report on Form 10-Q (this "Form 10-Q"), as well as the MD&A section included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”) on February 17, 2023 (the “2022 Form 10-K”).

Business Overview

AdvanSix is a diversified chemistry company playing a critical role in global supply chains, innovating and delivering essential products for our customers in a wide variety of end markets and applications that touch people’s lives, such as building and

construction, fertilizers, agrochemicals, plastics, solvents, packaging, paints, coatings, adhesives and electronics. Our reliable and sustainable supply of quality products emerges from the integrated value chain of our five U.S.-based manufacturing facilities. AdvanSix strives to deliver best-in-class customer experiences and differentiated products in the industries of nylon solutions, chemical intermediates and plant nutrients, guided by our core values of Safety, Integrity, Accountability and Respect. Our four key product lines are as follows:

•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. In addition, our Nylon 6 resin is used to produce nylon films which we sell to our customers primarily under the Capran® brand name.

•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 nylon fibers, films 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, 2023.

•Chemical Intermediates – We manufacture, market and sell a number of other 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 adhesives, paints, coatings, solvents, herbicides and engineered plastic resins. Other intermediate chemicals that we manufacture, market and sell include phenol, alpha-methylstyrene (“AMS”), cyclohexanone, 2-pentanone oxime, cyclohexanol, sulfuric acid, ammonia and carbon dioxide. With the acquisition of U.S. Amines Limited (“U.S. Amines”), we now produce alkyl and specialty amines serving high-value end markets such as agrochemicals and pharmaceuticals.

•Ammonium Sulfate – 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, 2023. We market and sell ammonium sulfate primarily to North American and South American distributors, farm cooperatives and retailers to fertilize crops.

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. Generally, prices for Nylon 6 resin and caprolactam reflect supply and demand trends in the marketplace as well as the value of the basic raw materials used in the production of caprolactam, consisting primarily of benzene and, depending on the manufacturing process utilized, natural gas and sulfur. 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 variation as a result of global changes in supply and demand. Nylon 6 resin prices generally track caprolactam prices, although prices set above the average commodity spread are achievable when nylon resin manufacturers, like AdvanSix, formulate and produce differentiated nylon resin products for current and new customer applications. Our differentiated Nylon 6 products, such as our wire and cable and co-polymer offerings, are typically valued at a higher level than commodity resin products.

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.

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 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.

We produce ammonium sulfate fertilizer continuously throughout the year as part of our manufacturing process, however, quarterly sales experience 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 America planting season runs from July through June. The new season fill typically occurs in the third quarter and proceeds sequentially into the following spring which is the peak period for fertilizer application for key crops in North America. As a result of this typical pattern, North American ammonium sulfate demand and pricing, particularly for our higher-value granular product, are typically the strongest in the first half of the year through application for the spring crop and then decline in the second half. Our export sales, primarily into South America, are predominantly of the standard grade product. Due to the ammonium sulfate fertilizer sales cycle, we occasionally build up higher inventory balances because our production is continuous 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 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

Business Operations

In the second quarter of 2019, the Company entered into an alliance with Oben Holding Group S.A. (“Oben”), a third-party producer of films for the flexible packaging industry. On September 8, 2023, the Company entered into an agreement to exit its alliance with Oben. The exit of the alliance provides a termination fee payable by Oben to AdvanSix in exchange for full transition of AdvanSix’s share of the alliance. The Company recorded a gain of $11.4 million in the third quarter of 2023. The gain represents management’s estimate of the value of the termination fee, which is calculated based upon a formula that takes into account a combination of historical and future performance, and is included as a component of Other non-operating (income) expense, net. Approximately 60% of the termination fee is subject to change as it is based on an estimate of future performance. This fee is payable in 3 installments, with the first installment of $4.4 million received in the fourth quarter of 2023. Subsequent installments are expected to be paid in the third quarters of 2024 and 2025.

On September 21, 2023, the Company was notified by a licensee of certain legacy ammonium sulfate fertilizer technology assets operated at the licensee's fertilizer manufacturing facility that it intends to close its facility no later than August 2024. As a result, the Company recognized a non-cash, pre-tax charge related to the assets located at the licensee's facility of approximately $4.5 million in the third quarter of 2023. The charge is included as a component of Other non-operating (income) expense, net. The remaining asset balance of $2.6 million, an amount equal to the cash-flows expected to be received through the end of the contract, will be depreciated through August 2024.

During the third quarter of 2023, the Company made a strategic decision to cease production of certain low-margin products in the oximes family. The Company incurred an approximately $2.4 million unfavorable impact to pre-tax income during the third quarter of 2023 primarily as a result of a non-cash write-down of the assets associated with these products.

Share Repurchase Authorization

On February 17, 2023, the Company announced that the Board authorized a share repurchase program of up to an additional $75 million of the Company's common stock, which was in addition to the remaining capacity available under the previously approved share 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 repurchase program has no expiration date and may be modified, suspended or discontinued at any time.

Hopewell, VA Collective Bargaining Agreements

On April 7, 2023, the Company issued a press release announcing that a labor strike had been initiated by the Hopewell South bargaining unit, consisting of the International Chemical Workers Union Council/the United Food and Commercial Workers, Local 591-C, the International Brotherhood of Electrical Workers, Local 666, the International Association of Machinists and Aerospace Workers, Local No. 10, and the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry, Local 851, affecting approximately 340 workers at the Company’s manufacturing facility in Hopewell, Virginia. The Company had robust contingency measures in place and was well prepared to support safe, stable and sustainable operations during this period. On May 8, 2023, the Company announced that the Hopewell South bargaining unit voted to ratify a new five-year collective bargaining agreement and that Hopewell South employees would return to work on May 10, 2023. The strike did not have a material impact on the Company’s results of operations.

On September 29, 2023, the Company’s Hopewell North bargaining unit, represented by the United Steelworkers, ratified a new five-year labor agreement in advance of the prior agreement’s anticipated expiration date of October 4, 2023. The ratified labor agreement affects approximately 130 workers at the Company’s manufacturing facility in Hopewell, Virginia.

Gross margin percentage decreased in the nine months ended September 30, 2023 compared to the prior year period (approximately 3%) due primarily to the impact of market-based pricing, net of raw material costs (approximately 3%).

Selling, General and Administrative Expenses


	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Selling, general and administrative expenses	$	21,585	$	23,069	$	70,711	$	65,120
Percentage of Sales	6.7%		4.8%		6.1%		4.2%

Selling, general and administrative expenses decreased by $1.5 million in the three months ended September 30, 2023 compared to the prior year period due to lower incentive-based compensation expense and reduction in IT and other functional support costs.

Selling, general and administrative expenses increased by $5.6 million in the nine months ended September 30, 2023 compared to the prior year period due primarily to increased functional support costs including upgrades to our enterprise resource planning system, costs associated with pursuing the business interruption insurance claim in connection with the June 2019 shutdown of cumene supplier, Philadelphia Energy Solutions, and a reduction in bad debt expense in the prior year period associated with a cash collection of a previously reserved customer receivable partially offset by lower incentive-based compensation costs.

Income Tax Expense


	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Income tax expense (benefit)	$	(2,076)	$	2,730	$	17,753	$	41,876
Effective tax rate	20.7%		21.4%		22.9%		23.2%

The Company’s effective tax rate for the three and nine months ended September 30, 2023 and 2022 differed from the U.S. federal statutory rate, due to the impacts of state taxes and executive compensation deduction limitations, offset by tax credits and the foreign-derived intangible income deduction. Additionally in 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.

The Company's effective tax rate for the three months ended September 30, 2023 slightly differed from the prior period due primarily to changes in state taxes, including the impact of state rate changes, additional tax credits, and a decrease in the foreign-derived intangible income deduction. The Company's effective tax rate for the nine months ended September 30, 2023 approximated the prior year.

On August 16, 2022, the Inflation Reduction Act of 2022 (the "IRA") was signed into law. This legislation includes significant changes relating to tax, climate change, energy and health care. Among other provisions, the IRA introduces a corporate alternative minimum tax (CAMT) on adjusted financial statement income of certain large corporations and a 1% excise tax on share repurchases. The Company is not currently subject to the CAMT which became effective for tax years beginning after December 31, 2022. The 1% excise tax is generally applicable to publicly traded corporations for the net value of certain stock that the corporation repurchases during the year and is also effective for tax years beginning after December 31, 2022. The impact of any excise tax imposed on the Company for share repurchases is generally accounted for as an equity transaction with no consequences to the Company's results of operations, and this provision of the law is not expected to have a material impact on the Company's financial condition. The IRA also includes significant extensions, expansions and enhancements related to climate and energy tax credits designed to encourage investment in the adoption and expansion of renewable and alternative energy sources. The Company continues to evaluate these energy credit provisions of the law in relation to our sustainability and environmental, social and governance initiatives.

Net Income


	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Net income (loss)	$	(7,977)	$	10,032	$	59,705	$	138,262

As a result of the factors described above, Net income (loss) was ($8.0) million and $59.7 million for the three and nine months ended September 30, 2023 as compared to $10.0 million and $138.3 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 (Loss) and Adjusted Earnings Per Share. Adjusted EBITDA is defined as Net income (loss) 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 (Loss), 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, 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 2022 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. 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, together with cash on hand and 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 2022 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 2023, the Company had approximately $22.1 million of cash on hand with approximately $329 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 $115 million in 2023 compared to $89 million in 2022, reflecting increased spend due to critical infrastructure, other maintenance, and growth and cost savings projects.

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 2023 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, 2023 and does not expect to make cash contributions during the fourth quarter of 2023. Additional contributions may be made in future years sufficient to satisfy pension funding requirements in those periods.

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


Date of Authorization	Authorized Amount (millions)		Authorized Amount Remaining as of September 30, 2023 (millions)
May 4, 2018	$	75.0	$	—
February 22, 2019	75.0		1.6
February 17, 2023	75.0		75.0
Totals	$	225.0	$	76.6

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, 2023, the Company has repurchased a total of 5,541,948 shares of common stock life-to-date, including 854,340 shares withheld to cover tax withholding obligations in connection with the vesting of awards, for an aggregate of $173.6 million at a weighted average market price of $31.33 per share. As of September 30, 2023, $76.6 million remained available for share repurchases under the current authorization. During the period from October 1, 2023 through October 27, 2023, we repurchased an additional 101,387 shares at a weighted average market price of $29.07 per share primarily under the currently authorized repurchase program.

As of September 30, 2023, 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 Company's 2022 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.

Credit Agreement

On September 30, 2016, the Company as the borrower, entered into a Credit Agreement with Bank of America, as administrative agent (the "Original Credit Agreement"), which was amended on February 21, 2018 pursuant to Amendment No. 1 to the Original Credit Agreement (the "First Amended and Restated Credit Agreement"), and further amended on February 19, 2020 pursuant to Amendment No. 2 to the First Amended and Restated Credit Agreement (after giving effect to the Second Amendment, the “Second Amended and Restated Credit Agreement”). The Second Amended and Restated Credit Agreement had a five-year term with a scheduled maturity date of February 21, 2023.

On October 27, 2021, the Company completed a refinancing of the Second Amended and Restated Credit Agreement by entering into a new Credit Agreement (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 new 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 has 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.

With the cessation of LIBOR on June 30, 2023 and subject to the First Amendment to the Credit Agreement, dated as of June 27, 2023, the Eurodollar Rate was replaced with the Adjusted Term SOFR as an alternative benchmark rate for purposes of the Credit Agreement. The transition was effective July 1, 2023. 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. In conjunction with the cessation of LIBOR, as of July 1, 2023, the applicable margin under the Credit Agreement was 0.25% for base rate loans and 1.25% for Adjusted Term SOFR loans and the applicable commitment fee rate was 0.15% per annum.

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 (i) 4.00 to 1.00 or less for the fiscal quarter ending December 31, 2021, through and including the fiscal quarter ending September 30, 2023 and (ii) 3.75 to 1.00 or less for each fiscal quarter thereafter (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, 2023 and through the date of the filing of this Form 10-Q.

We had a borrowed balance of $115 million under the Revolving Credit Facility at December 31, 2022. We borrowed an incremental net amount of $55 million during the nine months ended September 30, 2023, bringing the balance under the Revolving Credit Facility to $170 million, and available credit for use of approximately $329 million as of September 30, 2023. We expect that Cash provided by operating activities will fund future interest payments on the Company's outstanding indebtedness.

Cash Flow Summary


	Nine Months Ended September 30,
	2023		2022
Cash provided by (used for):
Operating activities	$	57,381	$	203,987
Investing activities	(71,429)		(160,053)
Financing activities	5,173		(34,340)
Net change in cash and cash equivalents	$	(8,875)	$	9,594

Cash provided by operating activities decreased by $146.6 million for the nine months ended September 30, 2023 versus the prior year period due primarily to (i) a $92.9 million unfavorable cash impact from working capital (comprised of Accounts and other receivables, Inventories, Accounts payable and Deferred income and customer advances) with a $51.9 million unfavorable cash impact from working capital for the nine months ended September 30, 2023 compared to a $41.0 million favorable cash impact in the prior year period, primarily due to the timing of payments and lower raw material prices in accounts payable of $81.8 million and the unfavorable impact of customer advances of $32.0 million driven by the unwinding of ammonium sulfate pre-buy advances and (ii) a $78.6 million decrease in net income. This was partially offset by (i) a $22.3 million favorable cash impact from Taxes receivable and (ii) a $14.4 million favorable cash impact from Other assets and liabilities driven primarily by a reduction in the net pension liability due to previous year cash contributions to the defined benefit pension plan during the nine months ended September 30, 2023 compared to the prior year period.

Cash used for investing activities decreased by $88.6 million for the nine months ended September 30, 2023 versus the prior year period due primarily to cash paid for the acquisition of U.S. Amines for approximately $97.5 million during the prior year period offset by increased cash payments for capital expenditures of approximately $8.0 million during the current year period due primarily to increased spend for critical infrastructure, other maintenance, and growth and cost savings projects.

Cash used for financing activities decreased by $39.5 million for the nine months ended September 30, 2023 versus the prior year period due primarily to payments for share repurchases of $37.7 million and cash paid for dividends of approximately $12.4 million during the nine months ended September 30, 2023 compared to $23.6 million and $11.1 million during the prior year period, respectively, partially offset by net borrowings of $55.0 million during the nine months ended September 30, 2023 compared to net borrowings of $0, where incremental borrowings equaled incremental repayments, 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, 2023
Capital expenditures in Accounts payable at December 31, 2022	$	14,879
Purchases of property, plant and equipment	75,334
Less: Capital expenditures in Accounts payable at September 30, 2023	(21,188)
Cash paid for capital expenditures	$	69,025

For 2023, we expect our total capital expenditures to be approximately $115 million compared to $89 million in 2022, reflecting increased spend due to critical infrastructure, other maintenance, and growth and cost savings projects. Capital expenditures are deployed for various ongoing investments and initiatives to improve reliability, yield and quality, expand production capacity and comply with HSE regulations.

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 2022 Form 10-K. While there have been no material changes to our critical accounting policies, or the methodologies or assumptions we apply under them, 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, 2023 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, 2023, a 25-basis point fluctuation in interest rates for the nine months ended September 30, 2023 would have resulted in an increase or decrease to our interest expense of approximately $0.4 million.

See “Note 12. Derivative and Hedging Instruments” to the Condensed Consolidated Financial Statements, included in Part I. Item 1 of this Form 10-Q, for a discussion relating to credit and market, commodity price and interest rate risk.

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 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 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 Chief Financial Officer have concluded that our disclosure controls and procedures are effective at a reasonable assurance level as of September 30, 2023, 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, 2023 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

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.

ITEM 1A. RISK FACTORS

There have been no material changes to our risk factors as previously disclosed in Item 1A of Part I of the Company’s 2022 Form 10-K, which are hereby incorporated by reference.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On May 4, 2018, the Company announced that the Board authorized a share repurchase program of up to $75 million of the Company’s common stock. On February 22, 2019, the Company announced that the Board authorized a share repurchase program of up to an additional $75 million of the Company's common stock, which was in addition to the remaining capacity authorized under the May 2018 share repurchase program. On February 17, 2023, the Company announced that the Board authorized a share repurchase program of up to an additional $75 million of the Company's common stock, which was in addition to the remaining capacity available under the previously approved share 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 repurchase program has no expiration date and may be modified, suspended or discontinued at any time.

The below table sets forth the repurchases of Company common stock, by month, for the quarter ended September 30, 2023. During the quarter ended September 30, 2023, 261,884 shares were purchased under our share repurchase program and 5,075 shares were withheld to cover tax withholding obligations in connection with the vesting of equity awards.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	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 September 2022, the FASB issued ASU No. 2022-04, Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations. The amendments in this ASU require that a buyer in a supplier finance program disclose sufficient quantitative and qualitative information about its supplier finance programs to allow a user of the financial statements to understand the program’s nature, activity during the period, changes from period to period and potential magnitude. On a retrospective basis, for each annual reporting period, an entity should disclose the key terms of the program, including a description of the payment terms, assets pledged as security or other forms of guarantees, the confirmed amount outstanding that remains unpaid, a description of where the obligations are presented in the balance sheet and a roll-forward of those obligations confirmed as well as the amount of obligations subsequently paid. In each interim reporting period, an entity should disclose the amount of confirmed obligations outstanding. The guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on roll-forward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption of the amendments in this update is permitted. The Company adopted ASU 2022-04, effective January 1, 2023, which did not have a material impact on the Company's consolidated financial position or results of operations upon adoption.

Commitments and Contingencies	Sep. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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 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.

The provision for income taxes was $17.8 million and $41.9 million for the nine months ended September 30, 2023 and 2022, respectively, resulting in an effective tax rate of 22.9% and 23.2%, respectively. The Company’s provision 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, 2023 and 2022 differed from the U.S. federal statutory rate, due to the impacts of state taxes and executive compensation deduction limitations, offset by tax credits and the foreign-derived intangible income deduction. 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. On August 16, 2022, the Inflation Reduction Act of 2022 (the "IRA") was signed into law. This legislation includes significant changes relating to tax, climate change, energy and health care. Among other provisions, the IRA introduces a corporate alternative minimum tax (CAMT) on adjusted financial statement income of certain large corporations and a 1% excise tax on share repurchases. The Company is not currently subject to the CAMT which became effective for tax years beginning after December 31, 2022. The 1% excise tax is generally applicable to publicly traded corporations for the net value of certain stock that the corporation repurchases during the year and is also effective for tax years beginning after December 31, 2022. The impact of any excise tax imposed on the Company for share repurchases is generally accounted for as an equity transaction with no consequences to the Company's results in operations, and this provision of the law is not expected to have a material impact on the Company's financial condition. The IRA also includes significant extensions, expansions and enhancements related to climate and energy tax credits designed to encourage investment in the adoption and expansion of renewable and alternative energy sources. The Company continues to evaluate these energy credit provisions of the law in relation to our sustainability and environmental, social and governance initiatives.

Fair Value Measurements	Sep. 30, 2023
Fair Value Disclosures [Abstract]
Fair Value Measurements	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. In July 2019, the Company entered into an interest rate swap transaction related to its credit agreement. The interest rate swap, considered a Level 2 liability, expired February 21, 2023. 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 March 31, 2023 and we concluded that an impairment for goodwill did not occur.

Accounting Policies [Abstract]
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, 2023, and its results of operations for the three and nine months ended September 30, 2023 and 2022 and cash flows for the nine months ended September 30, 2023 and 2022. 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, 2022 (the "2022 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, 2023 and 2022 were September 30, 2023 and October 1, 2022, respectively.
New 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 September 2022, the FASB issued ASU No. 2022-04, Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations. The amendments in this ASU require that a buyer in a supplier finance program disclose sufficient quantitative and qualitative information about its supplier finance programs to allow a user of the financial statements to understand the program’s nature, activity during the period, changes from period to period and potential magnitude. On a retrospective basis, for each annual reporting period, an entity should disclose the key terms of the program, including a description of the payment terms, assets pledged as security or other forms of guarantees, the confirmed amount outstanding that remains unpaid, a description of where the obligations are presented in the balance sheet and a roll-forward of those obligations confirmed as well as the amount of obligations subsequently paid. In each interim reporting period, an entity should disclose the amount of confirmed obligations outstanding. The guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on roll-forward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption of the amendments in this update is permitted. The Company adopted ASU 2022-04, effective January 1, 2023, which did not have a material impact on the Company's consolidated financial position or results of operations upon adoption.
