The Company's headquarters is located in Parsippany, New Jersey.

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 is a key driver of caprolactam prices because it is the common chemical compound used in the petrochemical derivatives, such as phenol and cyclohexane, which are the key feedstock materials for caprolactam, depending on the chosen manufacturing technology. Asphenol or cyclohexane, are derived from benzene. This price spread has historically experienced variation as a result theof global prices for caprolactam typically track as a spread over the price of benzene. Generally,changes in supply and demand. Nylon 6 resin prices generally track the cyclicality of caprolactam prices, although to the extent Nylon 6 resin producers are able to manufacture specialized nylon resin products, prices set above the average commodity spread are achievable.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 believe that Nylon 6 end-market growth will continue to generally track global GDP over the long-term. Carpet is the largest end-use for Nylon 6 in North America and has seen stable to declining demand growth for a number of years reflecting shifts in consumer preferences to hard flooring versus soft and the previous substitution to lower-cost polyester. The housing sector had seen an improving trend in recent years, however, residential construction markets have slowed through 2023 reflecting the rise in interest rates. While Nylon 6 has a stronger presence in commercial carpet applications, including hospitality and office, where the material is preferred for its durability and performance characteristics, growth in both residential and commercial markets are challenged. Applications such as engineered plastics and packaging have potential to grow at faster rates given certain macrotrends.

The global market for Nylon 6 resin and caprolactam has undergone significant change inover the past seven yearsdecade. Following a peak in 2011 through the first half of 2016, nylon and caprolactam prices experienced a cyclical period of downturn as Chinese manufacturers have entered the market and increased global supply at a time when demand growth has remained relatively stable. As a result of the increased capacity and competitive intensity, industry margins for Nylon 6 resin and caprolactam have declined to historic lowscompressed over this period. Throughout 2017, industryperiod to a low point in mid-2016. In the second half of 2016, capacity reductions by our competitors occurred in North America and Europe improved supply/demand fundamentals in North America while conditions globally remained dynamic. Industry spreads had fluctuated near marginal producer cost.cost since 2016, but, slowing global growth and soft end-market demand, combined with capacity increases and an uncertain macro environment, pressured pricing and spreads during the second half of 2019 and throughout 2020. In 2021, strong end-use demand, combined with industry operational upsets and supply chain disruptions, created an environment for robust performance in Nylon 6. Nylon end-uses are sensitive to consumer demand, which was softer overall through 2023, particularly in consumer durables and residential end markets. However, buyers have explored using Nylon 6 as a substitute for other resins where applications allow, based on the need for reliable, secure long-term supply and performance needs.

Competition across our product offerings is based on a variety of factors including price, reliability of supply, quality, product innovation, and quality. Other competitive factors include breadth of product line, R&D efforts and technical and managerial capability. While the competitive position of our individual products varies, we believe we are a significant competitor in each major product class. AdvanSix competesGenerally, we compete in global, fragmented markets against competitors with integrated manufacturers, such as BASF Corporation, Sinopec Limited, DOMO Chemicals GmbH, LANXESS AG and Ube Industries, Ltd. We also compete with manufacturers such as Li Peng Enterprise Co. Ltd. and Zig Sheng Industrial Co., Ltd. that produce only polymer resin; synthetic manufacturers of ammonium sulfate, such as Pasadena Commodities International; and phenol producers, such as Ineos. A number of our products are sold in markets with many competitors, some of whom have substantial financial resources and significant technological capabilities. Additionally, our competitors include companies withboth global operations as well as those operating only within specific geographic regions. AdvanSix competes with integrated manufacturers, such as Highsun Group Holdings Ltd., BASF Corporation, Sinopec Limited, DOMO Chemicals GmbH, Envalior and UBE Corporation. We also compete with synthetic manufacturers of ammonium sulfate, such as Pasadena Commodities International and Nutrien Ltd.; and stand-alone phenol and acetone producers, such as INEOS Phenol and Altivia. In the U.S. Amines business, the key alkyl amines U.S.-based competitor is Eastman Chemical Company.

We produce caprolactam, the key monomer used in the production of Nylon 6 resin, at our Hopewell plant using phenol produced at our Frankford plant and sulfur and natural gas obtained from third-party suppliers. In 2017,2023, caprolactam generated $288$298 million of sales. In 2017, 20162023, 2022 and 2015,2021, caprolactam sales were 19%, 17%16% and 18%19% of our total sales, respectively.

We producemanufacture, market and sell chemical intermediates to a range of customers for use in many different types of end-products. In 2017, our2023, chemical intermediates generated $487$438 million of sales, of which $399$297 million, or 82%68%, came from sales of acetone, phenol and cyclohexanone, and $88$141 million, or 18%32%, came from sales of our other chemical intermediates. In 2017, 20162023, 2022 and 2015,2021, sales of chemical intermediates were 33%29%, 31%26% and 30%32% of our total sales, respectively.

PhenolThe phenol we produce at our Frankford plant is a key chemical intermediate of caprolactam, and we produce the phenol we useused in our caprolactam manufacturing process at our Frankford plant. Approximately 75% to 80%process. The majority of the phenol we produce is used in production of caprolactam and other chemical intermediates at Hopewell, and approximately 20% to 25% of ourHopewell. Any remaining phenol is sold to customers for use in their product applications such as phenolic resins, epoxies and Bisphenol A.

All our acetone is sold to customers for use in end-productsproducts such as adhesives, paints, coatings,methyl methacrylate, polycarbonate, epoxy resins, ketones and solvents herbicidesused widely in automotive and other engineered plastic resins.construction, as well as agrochemicals. Acetone is typically used by our customers as a key raw material in the production of a variety of other chemicals which are then used in the applications listed above.

We also produce and sell alpha methylstyrene ("AMS"), methyl ethyl ketoxime ("MEKO"),AMS, cyclohexanone, cyclohexanol, acetaldehyde oximeoximes and 2-pentanone oxime. We use some of these products in our manufacturing process and sell somecyclohexanol to customers for use in end-products such as resins, inks, paints, coatings and agricultural chemicalelectronic components. The majority of cyclohexanone we produce is used in our caprolactam manufacturing process with the remainder sold to customers.

As a result of the U.S. Amines acquisition during the first quarter of 2022, we also produce and sell alkyl and specialty amines which are used in agrochemical intermediates, water treatment and detergents.pharmaceutical applications.

The primary raw material used in our manufacturing process is cumene, which is produced from benzene and propylene. We purchase cumene from multiple suppliers to ensure stability of supply and optimal terms. Other important raw materials used in our manufacturing process are natural gas and sulfur, which are used to produce caprolactam and ammonium sulfate. We purchase natural gas and sulfur from a diverse set of suppliers.

Historically, we have been able to renew contracts with our suppliers and obtain sufficient quantities of cumene, sulfur, natural gas and any other key raw materials. Global supply and demand can significantly impact the price of our key raw materials, and historically prices have been cyclical. We primarily mitigate our exposure to commodity price risk primarily through the use of medium- and long-term, formula-based price contracts with our suppliers and formula-based price agreements with customers. We continually seek to reduce costs of keycustomers which structurally pass through increases or decreases in raw materials and do not foresee any material constraints in the near term resulting from pricing or availability.costs.

We have a global sales force with global reach, long-standing customer relationships and deep expertise with our products, product applications and end-markets. We predominantly sell directly to our customers, primarily under contracts but also through spot transactions under purchase orders.orders and through distributors.

Such forward-looking statements are based on the beliefs of management, as well as assumptions made by, and information currently available to, our management. They are not guarantees of future performance and actual results could differ materially from those contemplated by the forward-looking statements as a result of certain factors detailed in our filings with the SEC. All subsequent written or oral forward-looking statements attributable to us or persons acting on our behalf are qualified in their entirety by this paragraph. We do not undertake to update or revise any of our forward-looking statements. Our forward-looking statements are also subject to risks and uncertainties that can affect our performance in both the near-andnear- and long-term. These forward-looking statements should be considered in light of the information included in this Form 10-K, including, in particular, the factors discussed below. These factors may be revised or supplemented in subsequent reports on Forms 10-Q and 8-K.

Risk Factors

You should carefully consider all information in this Form 10-K and each of the risks described below, which we believe are the principal risks we face. Any of the following risks could materially and adversely affect our business, financial condition and results of operations and the actual outcome of matters as to which forward-looking statements are made in this Form 10-K.

The industries in which we operate are highly competitive and experience cyclicality which can cause significant fluctuations in our cash flows. These industry dynamicsflows and may adversely affect our business, financial condition and results of operations.

Our historical operating results reflect the cyclical and sometimes volatile nature of the industries in which we operate including with respect to our Nylon 6 resin, caprolactam, and ammonium sulfate industries.fertilizer, phenol and acetone products. We experience cycles of fluctuating supply and demand for each of theour products we sell resulting in changes in selling prices and margins. Periods of high demand, tight supply and increasing operating margins tend to result in increases in capacity and production until supply exceeds demand, generally followed by periods of oversupply and declining prices. For example, in the past, nylon and caprolactam prices have experienced a cyclical period of downturn as the global market has experienced large increases in supply without a commensurate increase in demand. Decreases in the average selling prices of our products could have an adverse effect on our profitability. While we strive to maintain or increase our profitability by reducing costs through improving production efficiency, by emphasizing higher margin products and by controllingseeking to control transportation, selling and administration expense, we cannot assure you that these efforts will be sufficient to offset, fullyin whole or in part, the effect of possible decreases in pricing on our operating results. BecauseAs a result of the cyclical nature of our businesses,potential cyclicality, we cannot assure you that pricing or profitability in the future will be comparable to any historical period, including the most recent period shown in our operating results. Structural changes in industry and customer trends for our products could adversely affect our business, financial condition and results of operations.

We seek to run our complex production facilities on a nearly continuous basis for maximum efficiency and we rely on the integrity of our logistics operations for the uninterrupted operations of our business. While we have made significant annual capital improvements at our manufacturing plants and utilize maintenance excellence and mechanical integrity programs, operational issues have occurred for us in the past and may occur in the future, which could cause damage to our manufacturing and production equipment and ancillary facilities. Unplanned interruptions in our production capabilities may adversely affect our production costs, product lead times, our ability to supply our customers on a timely basis, potential loss of customers, and our earnings during the affected period.

Although our integrated manufacturing,As a result of the scale and the quantity and range of our product offerings, make us one of the most efficient manufacturers in our industry,as well as the significant level of integration across our manufacturing facilities, exposes uswe are also exposed to increased risk associated with unplanned downtime or material disruptions at any one of our production facilities, which have occurred in the past and which may occur in the future, and which could impact our supply chain and our manufacturing process.

We seek to mitigate the risk of unplanned downtime through regularly scheduled maintenance for both major and minor repairsUnplanned interruptions at all of our production facilities. We also utilize maintenance excellencefacilities have occurred in the past and mechanical integrity programsmay occur in the future, and maintain what we believe is an appropriate buffer inventory of intermediate chemicals necessary for our manufacturing process, both of which are intended to mitigate the extent of any production losses as a result of unplanned downtime. However, unplanned outages may still occur or we may not have enough intermediate chemical inventory at any given time to offset production losses. Our business interruption insurance coverage may not cover all costs or losses associated with unplanned downtime, or such insurance may not continue to be available in amounts or on terms acceptable to us, or at all. Moreover, taking our production facilities offline for regularly scheduled repairs can be an expensive and time-consuming operation with risk that discoverable items and delays during the repair process may cause additional unplanned downtime. Any such unplanned downtime at any of our production facilities may adversely affect our business, financial condition and results of operations.

Raw material price fluctuations and the ability of key suppliers to meet delivery requirements can increase the cost of our products and services, impact our ability to meet commitments to customers and cause us to incur significant liabilities.

The cost of raw materials, including cumene, natural gas and sulfur, is a key element in the cost of our products. Our inability to offset material price inflation through increased prices to customers, formula-based or long-term fixed price contracts with suppliers, productivity actions or commodity hedges could adversely affect our business, financial condition and results of operations.

Although we believe that our sources of supply for raw materials are generally robust,appropriate for our expected needs, it is difficult to predict what effectsthe impact that shortages of raw materials or price increases may have in the future. Our ability to manage inventory and meet delivery requirements may be constrained by our suppliers’ inability to scale production and adjust delivery of long lead-time products during periods of fluctuating demand. Our inability to fillsatisfy our supply needs would jeopardize our ability to fulfill obligations under contracts, which could, in turn, result in reduced sales and profits, contract penalties or terminations and damage to customer relationships.

When possible, we have purchased, and we plan to continue to purchase, raw materials, including cumene, natural gas and sulfur, through negotiated medium- or long-term contracts. To the extent we have been able to achieve favorable terms in our existing negotiated contracts, we may not be able to renew such contracts at the current terms or at all, and this may adversely impact our

results of operations. To the extentFurther, if the markets for our raw materials significantly change, we may be bound by the terms of our existing supplier contracts and obligated to purchase raw materials at disadvantaged terms as compared to other market participants.

Our operations require substantial capital and we may not be able to obtain additional capital that we needDisruptions in the future on favorable termstransportation or at all.

The developmentfacilities and commercializationship products to our customers. Transport and pipeline operators are exposed to various risks, such as extreme weather conditions, natural disasters, work stoppages, personnel shortages, and operating hazards, as well as interstate and international transportation requirements.

However, our failure to obtain raw materials, ship products or maintain sufficient buffer inventory could materially and technologies is uncertain and could adversely affectimpact our business, financial condition and results of operations.

The loss of one or more of our significant customers could adversely affect our business, financial condition and results of operations.

Our business depends on significant customers, many of whom have been doing business with us for decades. The loss of one or several significant customers may have an adverse effect on our business, financial condition and results of operations. In 2017,2023, our 10 largest customers accounted for approximately 44%39% of our total sales.sales across all product lines. Our largest customer is Shaw, Industries Group, Inc. (“Shaw”), one of the world’s largest consumers of Nylon 6 resin and caprolactam. We sell caprolactam and Nylon 6 resin which we sell to themShaw under a long-term contract.agreement. We typically sell to other customers under short-term contractsmaster services agreements, with one- to two-yearprimarily one-year terms, or by purchase orders. If our sales to any of our significant customers were to decline, we may not be able to find other customers to purchase the excess supply of our products. The loss of one or several of our significant customers, or a significant reduction in purchase volume by any of them, or significant unfavorable changes to pricing or other terms in contracts with any of them, could have an adverse effect on our business, financial condition and results of operations. We are also subject to credit risk associated with customer concentration. If one or more of our largest customers were to become bankrupt or insolvent, or otherwise were unable to pay for our products, we may incur significant write-offs of accounts that may have an adverse effect on our business, financial condition and results of operations.

We are subjectOur competitive position, as well as our failure to extensive environmental, healthdevelop and safety lawscommercialize new products or technologies to address our customers’ needs and regulations that may result in unanticipated loss or liability, whichto effectively compete, could adversely affect our business, financial condition and results of operations.

Various federal, state, localCompetition in the industries we serve is based on factors such as price, product quality and foreign governments regulateservice. Additionally, the dischargemarkets for our products are characterized by significant competition, both regionally and internationally, new industry standards, evolving distribution models, customer price sensitivity, and disruptive product and manufacturing process innovations. In addition to changes in regulations, the impact of materialshealth, sustainability, and safety concerns could increase the costs incurred by our customers to use our products and otherwise limit the use of these products, which could lead to decreased demand for these products. Any of these factors

could create pressure on pricing and gross margins and could adversely impact our business. As a result, our competitors may be able to deliver greater innovation, respond more quickly to new or emerging technologies and changes in market demand, allocate more resources to the development, marketing and sale of their products, successfully expand into emerging markets, improve their cost structures, or price their products more aggressively than us.

Our continued ability to enhance our existing product offerings, as well as the environmentsuccessful development and can impose substantial finescommercialization of new products and criminal sanctionstechnologies, are drivers to our future strategy.

Our ability to keep pace with our competitors and Environmental Matters” for more information on the environmental laws and regulations to which we are subject.

Hazards and nitrous oxide and because natural gas, a fossil fuel, is a primary raw material used in our production process. In addition, to the extent that GHG restrictions are not imposed in countries where our competitors operate or are less stringent than regulations that may be imposed in the United States, our competitors may have cost or other competitive advantages over us.

There are hazards associated with chemical manufacturing and the related storage and transportation of raw materials, products and wastes. These hazards could lead to an interruption or suspension of operations and could have an adverse effect on the productivity and profitability of a particular manufacturing facility, or on us as a whole. While we endeavor to provide adequate protection for the safe handling of these materials, issues could be created by various events, including natural disasters, severe weather events, acts of sabotage, human error, and performance by third parties, and as a result, we could face potential hazards such as piping and storage tank leaks and ruptures, mechanical failure, employee exposure to hazardous substances and chemical spills and other discharges or releases of toxic or hazardous substances or gases.

These hazards may cause personal injury and loss of life, damage to property and contamination of the environment, which could lead to government fines, work stoppage injunctions, lawsuits by injured persons, damage to our public reputation and brand and diminished product acceptance. If such actions are determined to be adverse to us or there is an associated economic impact to our business, we may have inadequate insurance or cash flow to offset any associated costs. Such outcomes could adversely affect our business, financial condition and results of operations.

Our business, financial condition and results of operations could be adversely affected by litigation and other commitments and contingencies.

We face risks arising from various unasserted and asserted litigation matters, including, but not limited to, product liability and claims for third-party property damage or personal injury stemming from alleged environmental or other torts.torts or otherwise. We have noted a nationwide trend in purported class actions against chemical manufacturers generally seeking relief such as medical monitoring, property damages, off-site remediation and punitive damages arising from alleged environmental or other torts without claiming present personal injuries. We also have noted a trend in public and private nuisance suits being filed on behalf of states, counties, cities and utilities alleging harm to the general public.

Various factors or developments can lead to changes in current estimates of liabilities such as a final adverse judgment, significant settlementsettlements or changes in applicable law. An adverse outcome or unfavorable development in any one or more of these matters could be material to our financial results and could adversely impact the value of any of our brands associated with any such matters.

In the ordinary course of business, we may make certain commitments, including representations, warranties and indemnities relating to current and past operations, including those related to divested businesses, and issue guarantees of third-party obligations. Additionally, we willmay be required to indemnify Honeywell for amounts related to liabilities allocated to, or assumed by, us under each of the Separation and Distribution Agreement, the Employee Matters Agreement and the Tax Matters Agreement entered into in connection with the Spin-Off.our spin-off. If we are required to make any such payments, the payments could be significant and could exceed the amounts we have accrued with respect thereto, adversely affecting our business, financial condition and results of operations.

Any acquisition, strategic relationship, joint venture or investment could disrupt our business and harm our financial condition. Our inability to successfully acquire and integrate other businesses, assets, products or technologies or realize the financial and strategic goals that were contemplated at the time of any transaction could adversely affect our business, financial condition and results of operations.

We actively evaluate acquisitions, strategic relationships, joint ventures, collaborations, and strategic investments in businesses, products or technologies that we believe could complement or expand our business, broaden our technology and intellectual property increase market share in our current markets or expand into adjacent markets or otherwise offer growth or cost-saving opportunities. Any of these transactions may be complex, time consuming and expensive, and may present numerous challenges and risks. In 2021, we completed the acquisition of certain assets of Commonwealth Industrial Services, Inc., and in February 2022, we completed the acquisition of U.S. Amines, Ltd.

Lack of control over the actions of our business partners in any strategic relationship, joint venture or collaboration could significantly delay the introduction of planned products or otherwise make it difficult or impossible to realize the expected benefits of such relationship. Any transactions may be complex, time consuming and expensive, and may present numerous challenges and risks. An investment in, or acquisition of, complementary businesses, products or technologies in the future could materially decrease the amount of our available cash or require us to seek additional equity or debt financing. We may not be successful in

negotiating the terms of any potential acquisition, conducting thorough due diligence, financing the acquisition or effectively integrating the acquired business, product or technology into

Failure to protect our intellectual property could adversely affect our business, financial condition and results of operations.

Intellectual property rights, including patents, trade secrets, confidential information, trademarks, trade names and trade dress, are important to our business. We will endeavor to protect our intellectual property rights in key jurisdictions in which our products are produced or used. However, we may be unable to obtain protection for our intellectual property in such key jurisdictions. Although we own and have applied for numerous patents and trademarks, we may have to rely on judicial enforcement of our patents and other proprietary rights. Our patents and other intellectual property rights may be challenged, invalidated, circumvented, and rendered unenforceable or otherwise compromised. If we must take legal action to protect, defend or enforce our intellectual property rights, any suits or proceedings could result in significant costs and diversion of our resources and our management’s attention, and we may not prevail in any such suits or proceedings. A failure to protect, defend or enforce our intellectual property could have an adverse effect on our business, financial condition and results of operations. Similarly, third parties may assert claims against us and our customers and distributors alleging our products infringe upon third-party intellectual property rights. Such claims could result in significant costs and diversion of our resources and our management’s attention and we may not prevail in any resulting suits or proceedings.

We also rely materially upon unpatented proprietary technology, know-how and other trade secrets to maintain our competitive position. While we institute and maintain policies, and internal security measures, and agreements to protect our trade secrets and other intellectual property, any failure to protect this intellectual property could negatively affect our future performance and growth.

We may be required to make significant cash contributions to our defined benefit pension plan.

After the Spin-Off, we sponsoredWe sponsor a defined benefit pension plan under which certain eligible AdvanSix employees willwho were employed by Honeywell prior to the spin-off earn pension benefits following the Spin-Off as if they remained employed by Honeywell. Significant changes in actual investment return on pension assets, discount rates, retirement rates and other factors could require unplanned cash pension contributions in future periods. Changes in discount rates and actual asset returns different from our anticipated asset returns can result in significant non-cash actuarial gains or losses. With regard to cash pension contributions, funding requirements for our pension plans are largely dependent upon interest rates, actual investment returns on pension assets and the impact of legislative or regulatory changes related to pension funding obligations. Our pension contributions may be material and could adversely impact our financial condition, cash flow and results of operations. We made no pension contributions of approximately $17 million in 2017, and we plan toduring 2023, but may make pension contributions in future periods sufficient to satisfy funding requirements.

We are required under U.S. Generally Accepted Accounting Principles (“GAAP”) to test our goodwill for impairment annually or more frequently if indicators for potential impairment exist. Indicators that are considered include significant changes in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends, or a significant decline in the Company’s stock price and/or market capitalization for a sustained period of time. In addition, we periodically review our intangible and other long-lived assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Factors that may be considered a change in circumstances indicating that the carrying value of our workforce is represented by labor unionsintangible and ourother long-lived assets may not be recoverable include slower growth rates, the loss of a significant customer, burdensome new laws, or divestiture of a business could be harmedor asset for less than its carrying value. There are inherent uncertainties in management’s estimates, judgments, and assumptions used in assessing recoverability of goodwill, intangibles, and other long-lived assets. Any material changes in key assumptions, including failure to meet business plans, a deterioration in the event ofU.S. and global

financial markets, an increase in interest rates, an increase in inflation, or other unanticipated events and circumstances, may decrease the projected cash flows or increase the discount rates and could potentially result in an impairment charge. We may be required to record a prolonged work stoppage.

We are exposed to risks from various events that are beyond our control, which may have significant effects on our results of operations. While we attempt to mitigate these risks through appropriate loss prevention measures, we may not be able to anticipate all risks, or to mitigate or reasonably and cost-effectively manage those risks that we do anticipate. We maintain property, cyber liability, business interruption and casualty insurance but such insurance may not cover all risks, loss, damages or expenses associated with our business and is subject to limitations, including deductibles and limits on the liabilities covered. Consequently, our operations could be adversely affected by circumstances or events in ways that are significant and/or long lasting. The risks and uncertainties identified herein are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial also may adversely affect us. If any known or unknown risks and uncertainties develop into actual events, these developments could have a material adverse effect on our business, financial condition and results of operations.

We are a borrower of funds under a credit facility. Our ability to make payments on and to refinance our indebtedness, including the debt incurred, as well as any future debt that we may incur, will depend on our ability to generate cash in the recruitmentfuture from operations or financings. Our ability to generate cash is subject to general economic, financial, competitive, legislative, regulatory and retentionother factors that are beyond our control. In addition, the terms of qualified personnel,our indebtedness include a number of restrictive covenants that impose significant operating and financial restrictions on us and limit our failureability to attractengage in actions that may be in our long-term best interests. These restrictive covenants may restrict our ability to take some or all of the following actions:

Extensive environmental, health and safety laws and regulations applicable to our operations, including initiatives related to discharges into the complex nature of our manufacturing business, our future performance is highly dependent upon the continued services of our key engineering personnel, scientistsair and senior management, the development of additional management personnelwater, hazardous waste, sustainability, global warming and the hiring of new qualified engineering, manufacturing, marketing, salesclimate change, may result in substantial costs and management personnel for our operations. Competition for qualified personnel in our industry is intense, and we may not be successful in attractingunanticipated loss or retaining qualified personnel. The loss of key employees, our inability to attract new, qualified employees or adequately train employees, or the delay in hiring key personnel,liability, which could negativelyadversely affect our business, financial condition and results of operations.

Primarily because of past operations resultat our current manufacturing locations and other locations used in our operations as currently conducted, we may be subject to potentially material liabilities related to the remediation of environmental hazards and to claims of personal injuries or property damages that may have been or may be caused by hazardous substance releases and exposures or other hazardous conditions. Lawsuits, claims and costs involving these matters may arise in the lossfuture. In addition, changes in laws, regulations and enforcement of critical and confidentialpolicies, the discovery of previously unknown contamination or other information and adversely impactrelated to individual sites, the establishment of stricter state or federal toxicity standards with respect to certain contaminants or the imposition of new clean-up requirements or remedial techniques could require us to incur additional costs in the future that would have a negative effect on our reputationbusiness, financial condition and results of operations.

Global cybersecurity threatsAdditionally, there are substantial uncertainties as to the nature, stringency and incidents can range from uncoordinated individual attemptstiming of any future regulations or changes in regulations, including discharges into the air and water, handling and disposal of hazardous wastes, remediation of soil and groundwater, and greenhouse gas (“GHG”) and water nutrient regulations. Due to gain unauthorized accessconcerns about risks associated with air, water, global warming and climate change, more stringent regulations may be imposed which could require us to information technology (“IT”) systemsincur additional capital expenditures or make changes to sophisticatedour operating activities that would increase our operating costs, reduce our efficiency, limit our output, increase our costs for or limit the availability of energy, raw materials or transportation or otherwise adversely affect our business, financial condition and targeted measures knownresults of operations. If enacted, more stringent GHG limitations are likely to have a significant impact on us because our production facilities emit GHGs such as advanced persistent threats, directedcarbon dioxide and nitrous oxide and because natural gas, a fossil fuel, is a primary raw material used in our production process. To the extent that GHG or other restrictions are not imposed in countries where our competitors operate or are less stringent than regulations that may be imposed in the United States, our competitors may have cost or other competitive advantages over us. In addition, increasing regulation of fuel emissions could substantially increase the distribution and supply chain costs associated with our products. Consequently, legislative and regulatory programs to reduce emissions of GHG could have an adverse effect on our business, financial condition and results of operations.

Heightened public focus on climate change, sustainability, and environmental issues has also led to increased cybersecurity protectiongovernment regulation and remediationmay cause certain of our key stakeholders to require that we meet certain standards, including customers or suppliers who may impose environmental standards on us as a part of doing business with them, all of which could increase the costs incurred by our customers to use our products and otherwise limit the use of these products, which could lead to decreased demand for these products.

Failure to maintain effective internal controls could adversely impact our ability to meet our reporting requirements.

We are required, under the Sarbanes-Oxley Act of 2002, (the “Sarbanes-Oxley Act”), to maintain effective internal control over financial reporting and disclosure controls and procedures. This includes performing system and process evaluations and testing of our internal control over financial reporting to allow management and our independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting, as required by the Sarbanes-Oxley Act, with auditor attestation of the effectiveness of our internal controls. If we are not able to comply with these requirements, or if we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our common shares could decline and we could be subject to penalties or investigations by the NYSE, the SEC or other regulatory authorities, which would require additional financial and management resources.

Effective internal controls are necessary for us to provide reasonable assurance with respect to our financial reports and to effectively prevent fraud. Internal controls over financial reporting may not prevent or detect misstatements because of inherent limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud. Therefore, even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements. If we fail to maintain the effectiveness of our internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in their implementation, our business and operating results could be harmed, we could fail to meet our reporting obligations, and there could be a material adverse effect on our stock price.

The ongoing process of implementing internal controls requires significant attention from management and we cannot be certain that these measures will ensure that we implement and maintain adequate controls over our financial processes and reporting in the future. Difficulties encountered in their implementation could harm our results of operations or cause us to fail to meet our reporting obligations. If we fail to obtain the quality of services necessary to operate effectively or incur greater costs in obtaining these services, our profitability, financial condition and results of operations may be materially and adversely affected.

CompletionIn connection with our spin-off, if the October 1, 2016 distribution by Honeywell of all of the Spin-Off was conditioned on Honeywell’s receiptthen outstanding shares of a written opinion of Cravath, Swaine & Moore LLP to the effect that the Distribution should qualify for non-recognition of gain and loss under Section 355 of the Code. The opinion of counsel did not address any U.S. state, local or foreign tax consequences of the Spin-Off. The opinion assumed that the Spin-Off was completed according to the terms of the Separation and Distribution Agreement and relied on the facts as stated in the Separation and Distribution Agreement, the Tax Matters Agreement, the other ancillary agreements, the Information Statement filed as Exhibit 99.1 to the Form 10 and a number of other documents. In addition, the opinion was based on certain representations as to factual matters from, and certain covenants by Honeywell and us. The opinion cannot be relied on if any of the assumptions, representations or covenants is incorrect, incomplete or inaccurate or is violated in any material

stockholder’s share of Honeywell’s earnings and profits and the U.S. stockholder’s basis in its Honeywell common stock. A discussion of the material U.S. federal income tax consequences of the Spin-Offspin-off can be found in theour Form 10.

If, due to any of our representations being untrue or our covenants being breached, it were determined that the Distributiondistribution did not qualify for non-recognition of gain and loss under Section 355 of the Code, we could be required to indemnify Honeywell for the resulting taxes and related expenses. Any such indemnification obligation could adversely affect our business, financial condition and results of operations. In addition, Section 355(e) of the Code generally creates a presumption that the Distribution would be taxable to Honeywell, but not to stockholders, if we or our stockholders were to engage in transactions that result in a 50% or greater change by vote or value in the ownership of our stock during the four-year period beginning on the date that begins two years before the date of the Distribution, unless it were established that such transactions and the Distribution were not part of a plan or series of related transactions giving effect to such a change in ownership. If the Distribution were taxable to Honeywell due to such a 50% or greater change in ownership of our stock, Honeywell would recognize gain equal to the excess of the fair market value of our common stock distributed to Honeywell stockholders over Honeywell’s tax basis in our common stock and we generally would be required to indemnify Honeywell for the tax on such gain and related expenses. Any such indemnification obligation could adversely affect our business, financial condition and results of operations.

General or industry-specific market conditions, stock market performance or macroeconomic and geopolitical factors unrelated to our performance may also affect our stock price. For these reasons, investors should not rely on recent or historical trends to predict future stock prices, financial condition, results of operations or cash flows. Volatility in our stock price could expose us to litigation, which could result in substantial costs and the diversion of management time and resources.

We cannot guarantee the timing, declaration, amount or payment of any dividends, and the terms of our indebtedness willcould limit our ability to pay dividends on our common stock.

We will evaluate whether to pay cash dividends to our stockholders and theThe timing, declaration, amount and payment of future dividends to stockholders, if any, will fallbe within the sole discretion of our Board. Among the items we will considerconsidered when establishing a dividend policy will be the capital intensive nature of our business and opportunities to retain future earnings for use in the operation of our business and to fund future growth. Additionally, the terms of our indebtedness may limit our ability to pay cash dividends. There can be no assurance that we will continue to pay a dividend in the future or continue to pay any dividend if we do commence paying dividends.future.

Stockholder percentage ownership in AdvanSix may be diluted in the future.

A stockholder’s percentage ownership in AdvanSix may be diluted in the future because of common stock-based equity awards that we have granted and expect to grant in the future to our directors, officers and other employees. In addition, we may issue equity to raise capital to finance our ongoing operations or as all or part of the consideration paid for acquisitions and strategic investments that we may make in the future or as necessary to finance our ongoing operations.future.

Certain provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated By-laws and Delaware law may discourage takeovers.

Several provisions of our Amended and Restated Certificate of Incorporation, Amended and Restated By-laws and Delaware law may discourage, delay or prevent a merger or acquisition that is opposed by our Board. These include, among others, provisions that:

None.

We consider the manufacturing facilities and technology centers and the other properties that we own or lease to be in good condition and generally suitable for the purposes for which they are used. Our manufacturing facilities are maintained through ongoing capital investments, regular maintenance and equipment upgrades. We believe our facilities are adequate for our current operations.

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

The United States Environmental Protection Agency (“EPA”) notified the Company in December 2016 that alleged violations, involving the enhanced leak detection and repair program and emission testing requirements, at the Company’s manufacturing facility in Hopewell, Virginia, in each case that were self-reported by the Company, may potentially may subject the Company to stipulated penalties under the 2013 consent decree among the Company, the U.S. and the Commonwealth of Virginia. The Company has discussed this matter with the EPA and negotiations to resolve it are ongoing. Although the outcome of the matter cannot be predicted with certainty, we do not believe that it will have a material adverse effect on our consolidated financial position, results of operations or operating cash flows.
