# A MESSAGE FROM THE CEO

John Fortson | President and Chief Executive Officer

## DEAR INGEVITY STOCKHOLDERS,

2023 was a busy year for Ingevity. In 2023, Ingevity accelerated the implementation of several key strategic initiatives that broaden our capabilities and diversify our product portfolio to meet the needs of global customers across all our businesses. In an environment that remained dynamic and challenging, our team doubled down on our commitment to being an innovative, forward thinking, best-in-class specialty chemicals business, and I am incredibly proud of their performance. We are excited about where we’re heading.

In early 2023, we began to see recovery in North American auto manufacturing following the downturn during the coronavirus pandemic and China’s production followed later in the year. Energy price spikes in Europe due to the conflict in the Ukraine moderated over the course of the year, providing cost relief for our manufacturing operations in the United Kingdom, but Europe entered an overall industrial slowdown, and we saw customer destocking in many of our businesses as customers remained cautious among economic uncertainty. Mid-year, the paper processing plant co-located on our North Charleston, South Carolina, manufacturing site for over 75 years announced it was closing, necessitating a complete transition of all shared site services to our plant. By the end of the year, increasing demand for crude tall oil (CTO) due to its use in the regulatory driven European biofuels market pushed prices for CTO to levels that rendered the feedstock inefficient for use in low margin chemicals markets. Despite these challenges in our Industrial Specialties markets, Pavement Technologies, hereafter known as Road Technologies, continued its strong performance and had a terrific year.

## Executing our strategy

In the midst of these economic and industry challenges, our team moved forward through 2023 with agility and zeal, and advanced key strategic initiatives to set the foundation for growth to propel our results in upcoming years. We took aggressive actions to mitigate the impact of CTO pricing on our legacy businesses and stabilize the company against the market’s volatile dynamics longer term. In April, we fully transitioned our Crossett, Arkansas, plant to oleo-based feedstocks such as soy, palm and canola oils, to eliminate reliance on single sourcing and broaden our capabilities to expand into new end markets. In November, we took further action to reduce our dependence on CTO by making the difficult decision to close our DeRidder, Louisiana, Performance Chemicals plant and exit some low margin Industrial Specialties markets served by chemistries manufactured in that location. These strategic changes marked a significant inflection point for Ingevity and I’m proud of the focus and dedication demonstrated by every employee as we advanced our repositioning plan and worked through the associated headwinds, and still achieved record results in other businesses in our portfolio.

## Delivering results

Performance Materials delivered record revenue and segment EBITDA* in 2023 and continued to see strong segment growth as global auto production recovered from diminished coronavirus pandemic production levels over the course of the year, particularly in Asia and North America. Advanced Polymer Technologies (APT), formerly known as our Engineered Polymers business, was reported as a separate segment at the beginning of the year to specifically delineate sales of our specialty caprolactone products with tremendous sustainability characteristics, and also have a name more relevant to our expanding product portfolio. APT continued strong business development, expanding into growth markets such as apparel and agriculture. Our Performance Chemicals segment was a tale of two businesses in 2023. Our Road Technologies business achieved another record year as the unique environmental benefits of our product portfolio drove global technology adoption, and our Industrial Specialties business, impacted by unprecedented CTO price levels, focused on diversifying the product portfolio to enter higher margin, less cyclical end markets and exit certain low margin markets while diversifying our raw material feedstocks.

## Investing in growth initiatives for our future

Ingevity fully integrated Ozark Materials into our newly named Road Technologies business (formerly Pavement Technologies) to broaden our impact in the pavement industry by offering products to meet customer needs from the base of the asphalt to the striping on the top of the road. We opened a new APT




# “We are confident in our ability to be a best-in-class specialty chemicals provider that is a leader in sustainability and our markets.”

Innovation Center to support technology development at our Warrington, United Kingdom, location, and advanced our strategic investment in Nexeon to identify more opportunities to support the electric battery industry using our carbon and our production and engineering capabilities.

## Prioritizing our world class team

As always, the safety of our team remains our top priority. In 2023 we launched a global Safety Pledge campaign, reaffirming each employee's commitment to our collective responsibility to prioritize the well-being and care of every individual at Ingevity, and saw results of our focus with a significant increase in near miss hazard reporting to identify and prevent future safety incidents. Our talent management teams were recognized for providing the highest positive candidate experience and received industry awards for our commitment to offering a robust benefits program to support employee health and financial wellness. We added international marketing and business strategy development expertise to our board of directors by electing Bruce Hoechner to the board, and also invested in talent to support our oleochemicals transition and battery technology initiatives.

## Advancing sustainability initiatives to Purify, Protect, and Enhance the world around us

Ingevity was awarded a Silver rating by EcoVadis, the independent evidence-based sustainability assessment organization. Our EcoVadis rating places us in the top quartile of all responding companies. Our Capa \( ^{\circledR} \)  caprolactone products earned additional biodegradability and compostability certifications that further endorsed the sustainable nature of our company and our products. Recognizing we all have a role to play as stewards for our environment, we took steps to address Scope 2 emissions related to Ingevity's United States manufacturing locations by entering into a renewable product purchase agreement to produce offsetting renewable energy and advance the company toward greenhouse gas reduction targets, and also added capacity to our environmental data collection and reporting capabilities to enable greater transparency for our sustainability initiative efforts.

Thank you for your interest and investment in Ingevity. We hope you share our enthusiasm for Ingevity and the exciting opportunities ahead as we advance bold plans to better ourselves, our company and our communities. We are excited about the future and confident in our ability to be a best-in-class specialty chemicals company that is a leader in sustainability and our markets. Looking forward to great things in 2024!

Best regards,

J. C. Fortson

## PART I

## ITEM 1. BUSINESS

## General

Ingevity Corporation provides products and technologies that purify, protect, and enhance the world around us. Through a diverse team of talented and experienced people, we develop, manufacture, and bring to market solutions that are largely renewably sourced and help customers solve complex problems while making the world more sustainable. Our products are used in a variety of demanding applications, including adhesives, agrochemicals, asphalt paving, bioplastics, coatings, elastomers, lubricants, pavement markings, publication inks, oil exploration and production and automotive components. We operate in three reporting segments: Performance Materials, Performance Chemicals and Advanced Polymer Technologies.

During the first quarter of 2023, we realigned our segment reporting structure to increase transparency for our investors and better align with how our chief operating decision maker intends to measure segment operating performance and allocate resources across our operating segments. We separated our engineered polymers product line from the Performance Chemicals reportable segment into its own reportable segment, Advanced Polymer Technologies. This reportable segment change also resulted in our Performance Chemicals reporting unit for goodwill being split into two separate reporting units for the purposes of goodwill impairment testing. In November of 2023, we announced an initiative to reposition our Performance Chemicals segment to enhance profitability and earnings stability as we execute our corporate strategy to focus on higher margin and higher growth specialty products, diversify feedstocks and optimize our manufacturing network. This initiative will result in the reduction, and in some cases exit, of historical primary end uses of our Industrial Specialties product line such as adhesives, publication inks, and oilfield as well as the closure of our Performance Chemicals' manufacturing facility in DeRidder, Louisiana. Refer to the section: Performance Chemicals, within Item 1: BUSINESS for more information.

Throughout this Annual Report on Form 10-K, except where otherwise stated or indicated by the context, "Ingevity," the "Company," "we," "us," or "our" means Ingevity Corporation and its consolidated subsidiaries and their predecessors.

Our business originated as part of the operations of our former parent company, Westvaco Corporation, in 1964, and we operated as a division of Westvaco Corporation and its corporate successors, including MeadWestvaco Corporation and WestRock Company (“WestRock”) until our separation from WestRock in May 2016. Our common stock began "regular-way" trading on the New York Stock Exchange in May 2016 under the symbol "NGVT."

Our principal executive offices are located at 4920 O'Hear Avenue, Suite 400, North Charleston, South Carolina 29405. Ingevity maintains a website at www.ingevity.com. We make available, free of charge through our website, our filings with the Securities and Exchange Commission (the "SEC"), including our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports, as soon as reasonably practicable after such items are filed with, or furnished to, the SEC. We also use our website to publish additional information that may be important to investors, such as presentations to analysts. Information contained in or connected to our website is not incorporated by reference into this Annual Report on Form 10-K. Reports we file with the SEC may also be viewed at www.sec.gov.

The table below illustrates our product lines and the primary end uses for our products by segment, as well as our revenue by segment for the fiscal year 2023. For more information on our U.S. and foreign operations, see Notes 4 and 19, to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K.

(2) In November of 2023 we announced an initiative to reposition our Performance Chemicals segment to enhance profitability and earnings stability as we execute our corporate strategy to focus on higher margin and higher growth specialty products, diversify feedstocks and optimize our manufacturing network. This initiative will result in the reduction, and in some cases exit, of historical end-use markets of our Industrial Specialties product line such as adhesives, publication inks, and oilfield. Refer to the section: Performance Chemicals, within Item 1: BUSINESS for more information.

## Seasonality

There are a variety of seasonal dynamics, including global climate and weather conditions, that impact our businesses, though none have currently materially affected our financial results, except in the case of the road technologies product line, where roughly 70 to 75 percent of revenue is generated between April and September. From a supply perspective, this seasonality is effectively managed through pre-season inventory build and active inventory management throughout the year.

## Energy

Our manufacturing processes require a significant amount of energy. We are dependent on natural gas to fuel the processes in our chemical refineries and activated carbon plants. Although we believe that we currently have a stable natural gas supply and infrastructure for our operations, we are subject to volatility in the market price of natural gas. We enter into certain derivative financial instruments to mitigate expected fluctuations in market prices and the resulting volatility of earnings and cash flow. All of our manufacturing processes also consume a significant amount of electricity and are located in regulated service areas that have stable electricity rate structures with reliable supply.

## Leveraging Sustainability

Throughout our Performance Materials, Performance Chemicals, and Advanced Polymer Technologies portfolios, we are a leader in adding value to products made from renewable materials and in derivatizing technologies that impart desirable environmental benefits in their use. To create a majority of our chemistries, we take crude tall oil ("CTO") from pine trees, hardwood sawdust (both co-products of the lumber, paper, and furniture-making industries), and plant based oils and convert them into products that benefit customers, the environment, and society. For the caprolactone-based products in our Advanced Polymer Technologies segment – although derived from traditional feedstocks – these products provide solutions that enable performance attributes in end-use markets that directly help customers and consumers meet sustainability goals.

Put simply: Ingevity’s products help customers reduce their ecological impact. Our asphalt emulsifiers enable pavement recycling that reuses up to 100 percent of existing materials to create longer-lasting roads. Our automotive activated carbon products improve the air we breathe by recovering 8 million gallons of gasoline daily. Our agriculture adjuvants provide enhanced performance in crop protection. And our alternative-fuel vehicle technology enables the use of renewable natural gas as fuel for pickup trucks and buses. The superior durability of caprolactone-based polyurethane technologies extends product life and the biodegradable performance of our thermoplastic polycaprolactones offers compostable end of-life solutions.

Our business is built on our ability to maximize the value and utility of materials over their lifecycle, and we will continue to enhance this value proposition through future acquisitions and new product development.



## Human Capital Management

## Core Values

Developed collaboratively by Ingevity employees in 2017, the IngeviWay is the cultural framework that shapes Ingevity’s future and enables our success. It describes who we are, what we want to be, and what’s important to us as we work together to fulfill our purpose to purify, protect and enhance the world around us.

In early 2022, we reinforced our IngeviWay foundation by launching “The IngeviWay in Action,” an initiative that raises the bar on expectations to build, inspire and lead, and better aligns how we work as a team to create the Ingevity of the future. By focusing on making a positive impact through everyday actions, “The IngeviWay in Action” bolsters the way we live our core values of safety and sustainability, maximize value for our people and our customers, continue our commitment to excellence, integrity and ethical behavior and drive to create innovative solutions.

## Talent

Our employees are critical to our success, and we strive to provide a safe, rewarding, and respectful workplace where our people have opportunities to pursue career paths based on skills, performance, and potential. Our success depends, in part, on our ability to attract, retain and motivate critical resources across production, technical, engineering, sales, and various functional disciplines.

## Labor Relations and Collective Bargaining

We currently employ approximately 1,700 employees (excluding employees at our DeRidder, LA manufacturing facility which will be closed in 2024), of whom approximately 75 percent are employed in the U.S. Approximately 56 percent of our production employees are represented by labor unions under various collective bargaining agreements ("CBA"). We engage in negotiations with labor unions for new CBAs from time to time based on expiration dates of agreements and statutory requirements. We consider our relationships with all salaried, union-hourly, and non-hourly employees to be positive and collaborative.

In 2023, the United Steel, Paper, Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, on behalf of its affiliated Local Union 0775 at our Wickliffe, Kentucky Performance Materials manufacturing facility ratified a four-year CBA, which expires on February 1, 2027. Also in 2023, the IBEW LOCAL Union No. 1753 at our Charleston, South Carolina Performance Chemicals manufacturing facility ratified a four-year CBA, which expires on June 20, 2026.

The Advanced Polymer Technologies manufacturing facility in Warrington, United Kingdom is in the process of their annual negotiations with the GMB Union. Further, the CBA at our Crossett, Arkansas Performance Chemicals manufacturing facility with the International Association of Machinists and Aerospace Workers Union ("IAM") expires on March 1, 2024. These combined CBA impact approximately 40 percent of the workforce at these two locations. The parties began contract renewal negotiations during the first quarter of 2024 and continue to operate under the same terms and conditions while negotiations are pending.

## Diversity, Equity, Inclusion and Belonging

Ingevity is guided by our IngeviWay vision for how we work together to engage the diversity, knowledge, energy, talents and expertise of all employees. This vision reflects our commitment to actively supporting an inclusive environment where all employees are heard, respected and empowered to grow to their fullest potential. Driving meaningful and sustainable growth as a company includes attracting and retaining top talent with a broad range of skills, experience and ideas, and we are focused on increasing recruitment of diverse talent.

A strategic and intentional focus on diversity, equity, inclusion and belonging enhances the employee experience and satisfaction. It also supports more effective innovation, enhanced customer experience, and a deeper understanding of the communities Ingevity serves. Our diversity recruiting strategy is focused on ensuring everyone has an equitable experience by diversifying our talent pipeline through diverse candidate slates and interview teams as well as gender-neutral job descriptions.

Our focus on advancing the diversity makeup of our leadership continues to positively impact our growth and success. Today, our board of directors is 30 percent women and 20 percent racially and ethnically diverse, and our executive team is 43 percent women-led and 14 percent racially and ethnically diverse.



## Performance Management

We assess employee performance comprehensively, taking into account behaviors and direct input from the employee, feedback, and the individual's progress toward goals, as well as their level of business impact. Achievements that bolster the team, our business, and our clients—internal and external—and our fundamental values are all included in the performance evaluation process. Our method involves keeping a codified record of employee performance at mid-year and end-of-year. It also includes a requirement for all Ingevity employees to ask for feedback from those who are aware of their performance and contributions. In order to boost productivity, provide positive business outcomes, and raise employee engagement, we encourage managers and their employees to have regular discussions. With our all-encompassing strategy, Ingevity is able to gain a comprehensive understanding of each worker's strengths and identify opportunities for growth and development.

## Health & Safety

Ingevity has a world-class safety program and a strong safety culture. Personal, process, and public safety are core values at Ingevity. We work hard to protect employees, contractors, and the communities where we operate from injuries, illnesses and incidents through the design and delivery of safe operations, continuous improvement of personal and process safety performance, management systems, and programs, a strong culture of compliance, and a commitment to zero harm to people and the environment.

In 2023, we continued our efforts to increase reporting of and response to near miss incidents to prevent more serious injuries before they occur. This included efforts to increase the number of near misses reported and an increase in reporting by a broader number of employees. We also continued to improve safety training, further expanded the use of leading indicators to ensure effective initiatives are proactively implemented, and improved incident investigation quality to ensure contributing factors are appropriately identified and addressed. Employees were trained on the importance of our Life-Saving Rules, put in place to prevent fatalities and serious injuries through leadership videos, monthly interactive training packages, and upgraded procedures, checklists, work permits, and audits. Additionally, in North America where the majority of our bulk shipments are executed, we abide by the American Chemistry Council’s Responsible Care practices for transporting our chemicals safely. We strategically utilize logistics providers that have committed to these higher standards of safety, security, stewardship, and sustainability.

## Governmental Regulations

Our manufacturing operations are subject to regulation by governmental and other regulatory authorities with jurisdiction over our operations. These regulations include the discharge of materials into the environment, the handling, storage, transportation, disposal, and clean-up of chemicals and waste materials, and otherwise relating to the protection of the environment, as well as other operational regulations, such as the Occupational Safety and Health Act ("OSHA") and the Toxic Substances Control Act ("TSCA") in the U.S., and the Registration, Evaluation and Authorization of Chemicals ("REACH") directives in the European Union, the United Kingdom, and other countries. It is not possible to quantify with certainty the material effects that compliance with these regulations may have upon the capital expenditures, earnings, or competitive position of Ingevity, but we currently anticipate that such compliance will not have a material adverse effect on any of the foregoing. Environmental and other regulations and related legal proceedings have the potential to involve significant costs and liability for Ingevity.

## Intellectual Property

Intellectual property, including patents, closely guarded trade secrets, and highly proprietary manufacturing know-how, as well as other proprietary rights, is a critical part of maintaining our technology leadership and competitive edge. Our business strategy includes filing patent and trademark applications where appropriate for proprietary developments, as well as protecting our trade secrets. We actively create, protect, and enforce our intellectual property rights. We are filing for and being granted patents for product and process developments for our Performance Materials business that we believe are both novel and consistent with trends in the technological development of engines. Our Evotherm \( ^{®} \)  Warm Mix Asphalt technology is supported by numerous global patents. Additionally, our caprolactone and related technologies are supported by numerous global patents and trademarks, as well as proprietary manufacturing and technical know-how. The protection afforded by our patents and trademarks varies based on country, scope, and coverage, as well as the availability of legal remedies. Although our intellectual property taken as a whole is material to the business, there is no individual patent or trademark the loss of which could have a material adverse effect on the business.



On July 19, 2018, we filed suit against BASF Corporation (“BASF”) in the U.S. District Court for the District of Delaware (the “Delaware Proceeding”) alleging BASF infringed Ingevity’s patent covering canister systems used in the control of automotive gasoline vapor emissions (U.S. Patent No. RE38,844) (the “844 Patent”). On February 14, 2019, BASF asserted counterclaims against us in the Delaware Proceeding, alleging two claims for violations of U.S. antitrust law (one for exclusive dealing and the other for tying) as well as a claim for tortious interference with an alleged prospective business relationship between BASF and a BASF customer (the “BASF Counterclaims”). The BASF Counterclaims relate to our enforcement of the 844 Patent and our entry into several supply agreements with customers of our fuel vapor canister honeycombs. The U.S. District Court dismissed our patent infringement claims on November 18, 2020, and the case proceeded to trial on the BASF Counterclaims in September 2021.

On September 15, 2021, a jury in the Delaware Proceeding issued a verdict in favor of BASF on the BASF Counterclaims and awarded BASF damages of approximately $28.3 million, which will be trebled under U.S. antitrust law to approximately $85.0 million. On May 18, 2023, the court in the Delaware Proceeding entered judgment on the jury's verdict, which commenced the post-trial briefing stage. On February 13, 2024, the court in the Delaware Proceeding denied BASF's motion for pre-judgment interest on its tortious interference claim as well as and our motion seeking judgment as a matter of law, or a new trial in the alternative. In addition, BASF has indicated it will seek attorneys' fees and costs in amounts that they will have to support at a future date. Unless the judgment is set aside, BASF will be entitled to post-judgment interest pursuant to the rate provided under federal law.

We disagree with the verdict, including the court’s application of the law and entry of judgment and intend to appeal. In addition, we may challenge the U.S. District Court’s November 2020 dismissal of our patent infringement claims against BASF. Ingevity believes in the strength of its intellectual property and the merits of its position and intends to pursue all legal relief available to challenge these outcomes in the Delaware Proceeding. Final resolution of these matters could take up to 24 months.

## Segments

## Performance Materials

We engineer, manufacture, and sell hardwood-based, chemically activated carbon products which are produced through a highly technical and specialized process primarily for use in gasoline vapor emission control systems in internal combustion engines and hybrid electric vehicles including cars, trucks, motorcycles, and boats. To maximize the productivity of our manufacturing assets, we also produce several other activated carbon products for food, water, beverage, and chemical purification applications.

Our automotive activated carbon products primarily take the form of granules, pellets, and honeycomb "scrubbers," which are primarily utilized in vehicle-based gasoline vapor emission control systems to capture gasoline vapors that would otherwise be released into the atmosphere as volatile organic compounds. The captured gasoline vapors are largely purged from the activated carbon and re-directed to the engine where they are used as supplemental power for the vehicle. In this way, our automotive activated carbon products are part of a system that improves the environment and fuel efficiency. Performance Materials' net sales for 2023, 2022, and 2021 were $586.0 million, $548.5 million, and $516.8 million, respectively. The chart below reflects our 2023 Performance Materials' net sales by geography. Sales are assigned to geographic areas based on the location of the party to which the product was shipped.




## Raw Materials and Production

Our Performance Materials segment serves customers globally from three manufacturing locations in the U.S. and two in China. The primary raw material (by volume) used in the manufacture of our activated carbon is hardwood sawdust. Sawdust is readily available and is sourced through multiple suppliers to protect against supply disruptions and to maintain competitive pricing.

We also utilize phosphoric acid to chemically activate the hardwood sawdust. This phosphoric acid is sourced through multiple suppliers to protect against supply disruptions and to maintain competitive pricing. The market price of phosphoric acid is affected by the global agriculture market as the majority of global phosphate rock production is used for fertilizer production and only a portion of that production is used to manufacture purified phosphoric acid.

## Customers

We sell our automotive technologies products to approximately 60 customers around the globe. In 2023, our ten largest customers accounted for approximately 82 percent of sales. We are the trusted source of these products for many of the world’s largest automotive parts manufacturers, including PHINIA Inc. (previously BorgWarner Inc.), A. Kayser Automotive System GmbH, Korea Fuel-Tech Corporation, MAHLE GmbH, and many other large and small component manufacturers throughout the global automotive supply chain. Our food, water, beverage, and chemical purification products are sold to approximately 50 customers globally. We sell our products primarily through our own direct sales force in North America, Europe, South America, Asia, and a smaller, focused network of third-party distributors that have established a strong direct sales and marketing presence in North America and China.

## Competition

Our competitors include Norit, Kuraray Co., Ltd., and several domestic U.S. manufacturers and distributors of imported products and Chinese manufacturers. Ingevity has a decades-long track record of providing activated carbon that achieves life-of-vehicle emission standards. Given the imperative for automotive manufacturers to produce vehicles for the U.S., Canada, and China markets capable of meeting life-of-vehicle emission standards, or potentially face expensive recalls and unfavorable publicity, our automotive activated carbon products provide our customers the low-risk choice for this high-performance application. Additionally, we are well-positioned to meet increasing emissions standards around the world.



## Performance Chemicals

Our Performance Chemicals segment is comprised of two product lines: road technologies (previously named pavement technologies) and industrial specialties. Our products are utilized in pavement construction, pavement preservation, pavement reconstruction and recycling, road markings, agrochemical dispersants, paper chemicals, and other diverse industrial uses. Our application expertise is often called upon by our customers to provide unique solutions that maximize resource efficiency. We have a broad and diverse customer base in this segment. In 2023, our top ten customers accounted for approximately 22 percent of our segment revenue, with the next 100 customers making up approximately 47 percent of our segment revenue. Performance Chemicals' net sales for 2023, 2022, and 2021 were $902.1 million, $875.1 million, and $688.9 million, respectively. The chart below reflects our 2023 Performance Chemicals' net sales by geography. Sales are assigned to geographic areas based on the location of the party to which the product was shipped.

In 2023, Ingevity began a transformation of the Performance Chemicals' industrial specialties product line. In the spring of 2023, Ingevity ceased the processing of CTO at the Crossett Arkansas facility and converted the facility to the processing of a variety of plant based feedstocks. In addition, during the fourth quarter of 2023, Ingevity announced the planned closure of the DeRidder, Louisiana CTO refinery and derivatives operations. Once this transformation is complete, Ingevity's participation in the rosin based adhesive and publication printing ink markets along with emulsifiers for drilling into the oilfield markets will be substantially reduced.

2023 Net Sales by Geography



## Raw Materials and Production

Our Performance Chemicals segment serves customers globally from six manufacturing locations in the U.S. Most of our industrial specialties and some of our road technologies products are derived from CTO, a co-product produced by softwood kraft pulp processors, such as WestRock and Georgia-Pacific LLC (“Georgia-Pacific”). We also produce products derived from lignin, which is extracted from black liquor, another co-product of softwood kraft pulp processing.

We typically source our CTO needs primarily through supply contracts. Most of our contracted volumes are sourced through two primary parties: WestRock and Georgia-Pacific. During 2023, we sourced approximately 82 percent of our CTO from WestRock and Georgia-Pacific combined. CTO accounted for approximately 26 percent of our consolidated cost of sales and 51 percent of our consolidated raw materials purchases in 2023.

The supply of CTO is generally inelastic and governed by the volume of softwood kraft pulp processing around the world. Also, there are regulatory pressures that may incentivize suppliers of CTO to sell CTO into alternative fuel markets (i.e., biofuels) rather than to historical end users such as Ingevity. CTO-based biofuel has been deemed to meet the EU’s Renewable Energy Directive, second phase (“RED II”) biofuel sustainability criteria. As a result of RED II and related government incentives, there has been a significant increase in demand for CTO and its derivatives during 2023. The increased demand, combined with the rationalization of softwood kraft pulp processing during 2023, has created pressure on CTO pricing and driven the cost of CTO to unprecedented levels, higher by as much as 300 percent in some cases.



In addition to these developments in the EU, various pieces of legislation regarding the use of alternative fuels have been introduced in the U.S. at both the federal and state level. Currently, none of the U.S. legislation mandates or provides incentives for the use of CTO or its derivatives as a biofuel. Future legislation in the U.S. and elsewhere may promote the use of CTO or its derivatives as a feedstock for the production of biofuels, further constraining supply.

In 2023, we took further actions to diversify our raw materials stream and began a transformation of the Performance Chemicals' industrial specialties product line. In April 2023, we converted our Crossett, Arkansas CTO facility to run on non-CTO plant-based natural oils including soy, canola and palm-based oils. We currently sell these products as well as derivatives into end markets for industrial applications. We have invested in production capability at our Crossett, Arkansas facility as we expand the commercialization of our product offerings in existing and new markets, which may include the personal care; home and industrial cleaners, as well as the biofuels market. Additionally, in November 2023, we announced the planned closure of the DeRidder, Louisiana CTO facility. With these combined actions we have CTO supply contracted for volumes that exceed our post-transformation manufacturing capacity. We are evaluating our requirements and working with our suppliers to adjust our contracted volumes. However, we expect to procure CTO volumes, under an existing long-term contract, in excess of production needs and will therefore need to balance our working capital requirements and sell, as necessary, excess CTO volumes to the open market.

The other key raw materials used in the Performance Chemicals business are maleic anhydride, ethoxylates, and ethylene amines. These are sourced where possible through multiple suppliers to protect against supply disruptions and to maintain competitive pricing.

## Markets Served

## Road Technologies

Our road technologies product line produces a broad line of innovative additives and technologies utilized globally in road construction and pavement preservation, including pavement reconstruction and recycling. With the 2022 acquisition of Ozark Materials, LLC and Ozark Logistics, LLC (collectively, “Ozark Materials”), we have added road striping technologies to the portfolio.

Road Construction. Evotherm \( ^{®} \) , our premier road construction additive, is a warm mix asphalt technology that promotes adhesion by acting as both a liquid antistrip and a warm mix asphalt. Once Evotherm \( ^{®} \)  is mixed into the binder utilized for road layer construction, production temperatures can be significantly cooler than conventional hot mix asphalt. Lower production temperatures allow our customers to reduce emissions and fuel use during road construction as well as extend their paving seasons into colder months.

Pavement Preservation. We provide an array of pavement preservation products that eliminate many traditional asphalt heating, mixing, and transportation demands – saving our customers time, energy, and money. Our technical team matches the right emulsifier and design to our customers' materials and conditions to create high-performing emulsions.

## ITEM 1A. RISK FACTORS

Based on the information currently known to us, we believe that the following information identifies the most significant risk factors affecting the Company. However, the risks and uncertainties we face are not limited to those set forth in the risk factors described below. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business. In addition, past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods.

If any of the following risks and uncertainties develop into actual events, these events could have a material adverse effect on our business, financial condition. or results of operations. In such case, the trading price of our Common Stock could decline.

## Operational Risks

There may be negative impacts to our business arising out of the closure of our plant in DeRidder, Louisiana.

On November 1, 2023, we announced our plan to close our plant in DeRidder, Louisiana (the "DeRidder Plant"). The anticipated timing, charges, and costs of the closure of the DeRidder Plant could materially differ from our estimates if the plant closure results in adverse legal or regulatory actions, if personnel required to effect the shutdown become unavailable, or we are affected by other factors not currently contemplated. As a result of the Deridder Plant closing and reduced CTO refining capacity, we may be obligated, under an existing CTO supply contract, to purchase CTO volumes through 2025 at amounts in excess of needed CTO volumes. We intend to manage our CTO inventories by reselling excess volumes in the open market. Depending on the then current market price for CTO at the time of such sales, we may have to sell the CTO at a loss when our contracted price exceeds market, which may adversely affect our financial condition and results of operations.

We are dependent upon third parties for the provision of certain critical operating services at several of our facilities.

We are dependent upon third parties for the provision of certain critical operating services, primarily utilities and related services (depending on the site, e.g., steam, compressed air, energy, water, wastewater treatment, hydrogen peroxide), at our Covington, Virginia Performance Materials facility, at our Warrington, United Kingdom Advanced Polymer Technologies facility, and at the following Performance Chemicals facilities: Crossett, Arkansas and North Charleston, South Carolina.

The third party providers of critical and non-critical services at our location in North Charleston, South Carolina have announced the cessation of these services. The services in North Charleston are currently being wound down, with only certain water supply and treatment services to be transitioned in 2024. We have incurred and expect to incur significant costs to provide these services ourselves or obtain these services from other third parties. While we are executing our plans to minimize disruption to our business, there is no guarantee that we will be able to replace these services on a timely and cost-effective basis. The costs associated with replacing these services may be significant and any delay in our ability to replace these services could result in interruptions to our operations, both of which could adversely affect our financial condition and results of operations.

For the third-party services that remain, any such services would be at risk if any of the counterparties were to idle or permanently shut down the associated mill or plant, or if operations at the associated mill or plant were disrupted due to natural or other disaster, or by reason of strikes or other labor disruptions, or if there were a significant contractual dispute between the parties. In the event that the applicable counterparty were to fail to provide the contracted services, we would be required to obtain these services from other third parties, most likely at an increased cost, or to expend capital to provide these services ourselves. The expenses associated with obtaining or providing these services, as well as any interruption in our operations as a result of the failure of the counterparty to provide these services, may be significant and may adversely affect our financial condition and results of operations.

Furthermore, in the event that WestRock’s Covington, VA paper mill’s wastewater treatment operations do not comply with permits or applicable law and WestRock is unable to determine the cause of such non-compliance, then we will be responsible for between 10 percent and 50 percent of the costs and expenses of such noncompliance (increasing in 10 percent increments per violation during each twelve-month period) despite representing less than 3 percent of the total wastewater volume. These costs and expenses may be significant and may adversely impact our financial condition and results of operations.



Additionally, several of our manufacturing facilities are leased. In the event we were to have a dispute with the landlord regarding the terms of the relevant lease agreements, or we were otherwise unable to fully access or utilize the leased property, the associated business disruption may be significant and may adversely affect our financial condition and results of operations.

Disruptions at any of our facilities could negatively impact our production, financial condition and results of operations.

Disruptions to any of our manufacturing operations or other facilities, due to natural disasters and extreme weather, such as a hurricane, tropical storm, earthquake, tornado, severe weather, flood, fire or other unanticipated problems such as labor difficulties, pandemics, equipment failure, cyberattacks or other cybersecurity incidents, capacity expansion difficulties or unscheduled maintenance, could cause operational disruptions of varied duration. Also, many of our production employees are governed by collective bargaining agreements (“CBAs”). The CBA at our Warrington, United Kingdom Advanced Polymer Technologies manufacturing facility with GMB Union expired on January 15, 2024. The parties began contract renewal negotiations during the first quarter of 2024 and continue to operate under the expired CBA while negotiations are pending. Further, the CBA at our Crosssett, Arkansas Performance Chemicals' manufacturing facility with the International Association of Machinists and Aerospace Workers Union ("IAM") expires on March 1, 2024. The parties began contract renewal negotiations during the first quarter of 2024. While the Company has generally positive relations with its labor unions, there is no guarantee the Company will be able to successfully negotiate new union contracts without work stoppages, labor difficulties or unfavorable terms. In addition, existing CBAs may not prevent a strike or work stoppage at the applicable plant.

These types of disruptions could materially adversely affect our financial condition and results of operations to varying degrees depending upon the facility, the duration of the disruption, and our ability to shift business to another facility or find alternative sources of manufacturing capacity. Any losses due to these events may not be covered by our existing insurance policies or may be subject to certain deductibles. In certain cases, we have products, such as our extruded honeycomb and caprolactone products, that are only made at one facility. While we have some redundancies within the facilities that are the sole manufacturer of certain products, we have limited ability to make these products at other facilities.

## Supply Chain Risks

Our Performance Chemicals segment is highly dependent on CTO as a raw material, which is in limited supply, and has been and may continue to be subject to significant price increases resulting in costs that we may not be able to pass through to customers.

CTO is a key raw material in our industrial specialties and some of our road technologies product lines within our Performance Chemicals segment. Availability of CTO is directly linked to (as it is a co-product of) the production output of kraft paper mills using softwood, primarily pine trees, as their feedstock, (i.e., pulp). Softwood pulp is the predominant fiber source for packaging grades of paper as well as fluff pulp for personal care products. As a result, there is a finite global supply of CTO, with global demand for softwood pulp driving the global supply of CTO. Further, some pulp or paper mills may choose to consume their production of CTO to meet their energy needs or reduce their carbon footprint rather than sell the CTO to third parties, further constraining the availability of CTO and increasing inflationary pricing pressure as a result. Weather conditions have in the past and may in the future affect the availability and quality of pine trees used in the kraft pulping process and, therefore, the availability of CTO that meets Ingevity's quality standards. Geopolitical risk factors could constrain CTO availability. For example, sanctions imposed on Russia in 2022 have constrained the global CTO supply by approximately 10 percent.

CTO-based biofuel has been deemed to meet the EU’s Renewable Energy Directive, second phase (“RED II”) biofuel sustainability criteria. As a consequence of RED II and related government incentives, there has been a significant increase in demand for CTO and its derivatives resulting in exponential price increases for CTO and its derivatives. Pricing for CTO (which accounted for approximately 26 percent of all of our cost of sales and 51 percent of our raw materials purchases for 2023) is subject to pricing pressures due to limited supply elasticity of the product and competing demands for its use. The impacts of RED II coupled with a reduction in demand in industrial end markets have negatively impacted our ability to pass through any increases in our cost of CTO to our customers, with a resulting negative impact on our results of operations. If we remain unable to pass through the increased CTO costs to our customers or transition to lower cost raw materials on a timely and cost-effective basis, our results of operations could continue to be negatively impacted and we may be placed at a competitive disadvantage relative to certain competitors who rely on different primary raw materials or who have more favorable terms with their CTO suppliers.



We typically source our CTO needs through supply contracts. Some of our CTO supply contracts permit periodic adjustment or negotiation of pricing and other terms that may result in an unfavorable impact on our financial results. There can be no guarantee that pricing, CTO volume, and other terms will not be materially impacted as a result of these adjustments or negotiations. If any of our suppliers fail to meet their respective obligations under our supply agreements or we are otherwise unable to procure an adequate supply of CTO, or are unable to pass through significant cost increases to customers, our current level of production could be constrained and our results of operations could be materially and adversely affected.

We purchase a variety of other raw materials, which are also subject to pricing pressures and limited availability; inability to procure these raw materials or to pass on price increases could negatively impact our operations or financial results.

The Company purchases a variety of other raw materials from third parties for its manufacturing operations, including, but not limited to, hardwood sawdust, phosphoric acid, ethylene amines, black liquor, maleic/fumaric acid, hydrogen peroxide, cyclohexanone, and ethoxylates. Each raw material is subject to its own supply and demand dynamics which may, at times, limit availability and/or cause price volatility. The Company may be unable to procure the quantities of raw materials it needs which could negatively impact our operations or we may be unable to pass through price increases to our customers which could negatively impact our financial results. For example, our Performance Chemicals segment produces many products derived from lignin, which, like CTO, is a co-product of the kraft pulping process. Lignin is in limited supply and if we are unable to secure a sufficient amount of lignin on a cost-effective basis we could suffer disruption to our road technologies business, which could negatively impact our financial results and our results of operations.

Disruptions within our supply chain have negatively impacted, and could continue to negatively impact, our production, financial condition and results of operations.

We have been, and could continue to be, adversely affected by disruptions within our supply chain and transportation network. Our products are transported by truck, rail, barge or ship primarily by third-party providers. The costs of transporting our products could be negatively affected by factors outside of our control, including rail service interruptions or rate increases, extreme weather events, tariffs, rising fuel costs, and capacity constraints. Recently, the Panama Canal drought and Suez Canal attacks have, and could continue to, adversely impact the reliability and cost of our export shipments to customers. Significant delays or increased costs relating to transportation could materially affect our financial condition and results of operations. Disruptions at our suppliers could lead to volatility or increases in raw material or energy costs and/or reduced availability of materials or energy, potentially affecting our financial condition and results of operations.

## Market Risks

Adverse conditions in the automotive market may negatively impact demand for our automotive carbon products.

Sales of our automotive activated carbon products are tied to global internal-combustion-engine (“ICE”) and hybrid electric vehicle automobile (“HEV”) production levels. ICE and HEV automotive production in the markets we serve can be affected by macro-economic factors such as interest rates, fuel prices, shifts in vehicle mix (including shifts toward alternative energy vehicles), consumer confidence, employment trends, regulatory and legislative oversight requirements, and trade agreements.

The Company’s road technologies product line is heavily dependent on government infrastructure spending.

A significant portion of our customers’ revenues in our road technologies business is derived from contracts with various foreign and U.S. governmental agencies, and therefore, when government spending is reduced, our customers’ demand for our products is similarly reduced. While we do not do business directly with governmental agencies, our customers provide paving services to, for example, the governments of various jurisdictions within North America, South America, Europe, China, Brazil and India, and revenue either directly or indirectly attributable to such government spending continues to remain a significant portion of our revenues. Government business is, in general, subject to special risks and challenges, including: delays in funding and uncertainty regarding the allocation of funds to federal, state and local agencies; delays in spending or reductions in other state and local funding dedicated for transportation projects; other government budgetary constraints, cutbacks, delays or reallocation of government funding; long purchase cycles or approval processes; our customers’ competitive bidding and qualification requirements; changes in government policies and political agendas; and international conflicts or other military operations that could cause the temporary or permanent diversion of government funding from transportation or other infrastructure projects.



Certain of the Company’s products are sold into cyclical end-markets, such as the automotive market and the apparel market, which are impacted by changes in consumer and industrial demand.

Certain of our products are sold into end-markets that are cyclical and subject to frequent and rapid technology changes, changes in consumer preferences, evolving standards, and changes in product supply and demand. For example, demand for our Advanced Polymer Technologies products in the automotive market, where our products are formulated into automotive resins and coatings and various components, may be affected by technological advances, changing automotive original equipment manufacturer ("OEM") specifications, and global automobile production levels. Demand for our Advanced Polymer Technologies products which are sold into footwear adhesives and structural support, may be affected by consumer discretionary spending and changes in consumer preferences. Additionally, sales of our industrial specialties products may be negatively impacted due to reduced global industrial demand. The impact of these changes may lead to increased competition from competing and substitute products and downward pricing pressures on our customers, and therefore, our Advanced Polymer Technologies and industrial specialties product offerings.

## We face competition from new technologies and new or emerging competitors.

Our industries and the end-use markets into which we sell our products experience periodic technological change and product improvement. Our future growth depends on our ability to gauge the direction of commercial and technological progress in key end-use markets, to swiftly identify and respond to disruptive technologies, and to fund and successfully develop, manufacture, and market products in such changing end-use markets. If we fail to keep pace with the evolving or disruptive technological innovations in our end-use markets on a competitive basis, our financial condition and results of operations could be adversely affected.

In the Performance Materials segment, there is competition from other activated carbon manufacturers. These competitors are trying to develop more advanced and alternative activated carbon products that could more effectively compete with our products in automotive applications. There is also competition in automotive applications from non-activated carbon competitors and product offerings. For example, multiple OEMs are using sealed tanks in certain subsets of their vehicles to comply with the strict emission regulations (i.e., Tier 3/LEV III) in the U.S. While sealed tank fuel systems generally require an increased sized pelleted activated carbon canister to deal with refueling emissions, in most cases, they do not use an extruded honeycomb to meet current U.S. and California regulations. There is also emerging competition in the "honeycomb" space, which may impact sales of the Company's products. If a competitor were to succeed in developing products that are better suited than ours for automotive evaporative emissions capture applications and/or a competitive technology, such as, but not limited to, sealed gas tanks, our financial results could be negatively impacted.

In addition, the adoption of electric and hydrogen fuel cell vehicles is increasing in the U.S. and other parts of the world. Consumer demand for these alternative-fueled vehicles is expected to continue to increase significantly in future years as certain states and international governments implement limits on the sale of vehicles with ICE with various time lines to phase out sales of ICE vehicles. A reduction in the sales of vehicles with internal combustion engines would reduce demand for our activated carbon automotive products. Our long-term strategy is to grow our sales of products for applications in all-electric and hydrogen fuel cell vehicles to off-set the expected decline in activated carbon sales for ICE. If we are unable to develop products for all-electric and hydrogen fuel cell vehicles or grow sales fast enough, our business and results of operations could be adversely impacted. The process of designing and developing new technology and related products is complex, costly, and uncertain and may require us to retain and recruit talent in areas of expertise outside of our current core competencies. There can be no assurance that such advances in technology will be feasible or will occur in a timely and efficient manner.

Certain of our products face competition from substitute products where the costs of different raw material inputs can impact the price competitiveness of our products and negatively impact our sales and/or profits as we respond to substitute product competition.

Gum rosin-based products and hydrocarbon resins compete with our TOR-based resins in the adhesives market. The price of gum rosin has a significant impact on the market price for TOR and rosin derivatives and is driven by labor rates for harvesting, land leasing costs, and various other factors that are not within our control. Hydrocarbon resins, for example, C5 resins, are co-products from the manufacture of isoprene (synthetic rubber). Availability and pricing are determined by the supply/demand dynamics for synthetic rubber as well as the price of crude oil as the feedstock for isoprene and various other factors that are not within our control. Animal and plant based fatty acids compete with TOFA products in lubricant and industrial specialties. The market price for our TOFA and oleochemical products are impacted by the prices of other fats and



oils, and the prices for other fats and oils are driven by actual and expected harvest rates, petroleum oil prices, and the biofuel market. Other monomers, thermoplastics, and polyols compete with our caprolactone-based products. The price for our products is impacted by the prices of competitive substitutes which are influenced by oil prices as well as other supply and demand factors. We may not be able to pass through raw material cost increases, or we may lose market share if we do not effectively manage our pricing, which in either case could negatively impact our financial results.

Additionally, the price of energy may directly or indirectly impact demand, pricing or profitability for certain of our products. As petroleum oil prices can change rapidly, Ingevity products may be disadvantaged due to the fact that CTO is a thinly traded commodity with pricing commonly established for periods ranging from one quarter to one-year periods of time. Due to this, alternative technologies which compete with product offerings provided by Ingevity may be advantaged from time to time in the marketplace. Protracted periods of high volatility or sustained oversupply of petroleum oil may also translate into increased competition from petroleum-based alternatives. In addition, pricing for competing oleochemicals such as palm or soybean is likely to put further pressure on pricing of the Company’s products during periods of depressed petroleum prices. We are diversifying our raw materials to include oleochemical based products, however, there can be no guarantee that we will be able to produce and commercialize oleochemical based products on an efficient and profitable basis in the near term.

## We are dependent on certain large customers.

We have certain large customers in particular businesses, the loss of which could have a material adverse effect on the applicable segment’s sales and, depending on the significance of the loss, our results of operations, financial condition or cash flows. Sales to the Company’s ten largest customers (across all three segments) accounted for 31 percent of total sales for 2023. No customer accounted for more than 10 percent of total sales for 2023. With some exceptions, our business with those large customers is based primarily upon individual purchase orders. As such, our customers could cease buying our products from us at any time, for any reason, with little or no recourse. If a major customer or multiple smaller customers elected not to purchase products from us, our financial condition and results of operations could be materially adversely affected.

## We are dependent on attracting and retaining key personnel.

We are dependent upon our production workers, as well as upon engineering, technical, sales, and application specialists, together with experienced industry professionals and senior management. Our success depends, in part, on our ability to attract, retain and motivate key talent. Our failure to attract and retain individuals making significant contributions to our business could adversely affect our financial condition and results of operations.

## The inability to make or effectively integrate future acquisitions may negatively affect our results.

As part of our growth strategy, we may pursue acquisitions of businesses and product lines or invest in joint ventures. The ability to grow through acquisitions or other investments depends upon our ability to identify, negotiate, finance, complete, and integrate suitable acquisitions or joint venture arrangements. There can be no assurances that we will be able to integrate these acquisitions in an efficient and cost-effective manner or that these acquisitions or joint ventures will generate the expected value.

Acquisitions and other investments may expose us to liability from the target company and/or joint venture partner. Acquisition and investment target companies may be or may become involved in disputes regarding intellectual property and other aspects of their businesses or may be subject to liabilities that are unknown at the time of the transaction, including liabilities under environmental or tax laws. Depending on the nature of our investment and/or structure of an acquisition, we may take on or be exposed to such liability, which could materially impact our business, financial condition, or results of operations.

As we rely on information technologies to conduct our business, cyber-attacks, data and privacy breaches, or a failure of information technology systems could disrupt our operations and expose us to liability, which could cause our business and reputation to suffer.

We rely on our information technology systems, some of which are managed by third parties, to support, manage and maintain the day-to-day operations and activities of our business, including our manufacturing facilities, customer and vendor transactions, and financial, accounting, and business records. In addition, we collect and store certain data, including proprietary business information, and may have access to confidential or personal information that is subject to privacy and security laws and regulations.



The secure processing, storage, and transmission of sensitive, confidential, and personal data is critical to our operations and business strategy. We have instituted a system of security policies, procedures, capabilities, internal controls and audits based on our pursuit of ISO 27001 certification, designed to protect this information. Additionally, we engage third-party threat detection, penetration testing, and monitoring services which includes a global cybersecurity incident response team. Despite our security architecture and controls, and those of our third-party providers, we may be vulnerable to cyber-attacks, computer viruses, security breaches, ransomware attacks, inadvertent or intentional employee actions, system failures, and other risks that could potentially lead to the compromising of sensitive, confidential or personal data, improper use of our, or our third-party provider systems, solutions or networks, unauthorized access, use, disclosure, modification or destruction of information, and operational disruptions. We also maintain an information security risk insurance policy to help mitigate the financial consequences of these risks, however, there is no guarantee that such a policy will be sufficient to address such costs. In addition, the global regulatory environment pertaining to information security and privacy is increasingly complex, with new and changing requirements, such as the European Union’s General Data Protection Regulation (“GDPR”), California Consumer Privacy Act (“CCPA”), and the China Cybersecurity Law and Personal Information Protection Law. GDPR, which applies to the collection, use, retention, security, processing, and transfer of personally identifiable information of residents of EU countries, mandates new compliance obligations and imposes significant fines and sanctions for violations. CCPA requires companies to provide new data disclosure, access, deletion, and opt-out rights to consumers in California. Implementing and complying with these laws and regulations may be more costly or take longer than we anticipate, or could otherwise affect our business operations. Information security breaches, cyber incidents, and disruptions, or failure to comply with laws and regulations related to information security or privacy, could result in legal claims or proceedings against us by governmental entities or individuals, significant fines, penalties or judgements, disruption of our operations, remediation requirements, changes to our business practices, and damage to our reputation, which could adversely affect our business, financial condition or results of operations.

Complications with the design or implementation of our new enterprise resource planning (“ERP”) system could adversely impact our business and operations.

We have recently completed a complex, multi-year implementation of a new ERP system that was necessary due to the finite life of the existing operating system. The ERP system implementation required the integration of the new ERP system with multiple new and existing information systems and business processes in order to maintain the accuracy of our books and records and to provide our management team with information important to the operation of our business. If the ERP system does not operate as intended, the effectiveness of our internal control over financial reporting could be negatively impacted.

## International Operations Risks

## We are exposed to the risks inherent in international sales and operations.

In 2023, sales to customers outside of the U.S. made up approximately 37 percent of our total sales, and we sell our products to customers in approximately 75 countries. We have exposure to risks of operating outside the U.S., including: fluctuations in foreign currency exchange rates, including the euro, pound sterling, Japanese yen and Chinese renminbi; restrictions on, or difficulties and costs associated with, the repatriation of cash from foreign countries to the U.S.; difficulties and costs associated with complying with a wide variety of complex laws, treaties and regulations, which may carry significant penalties for non-compliance; unexpected changes in political or regulatory environments; earnings and cash flows that may be subject to tax withholding requirements or the imposition of tariffs, exchange controls or other restrictions; geopolitical and economic instability, including the wars in Ukraine and the Gaza region; general country strikes or work stoppages; unforeseen public health crises, such as pandemic and epidemic diseases; import and export restrictions, tariffs, and other trade barriers or retaliatory actions; difficulties in maintaining overseas subsidiaries and international operations; difficulties in obtaining approval for significant transactions; government limitations on foreign ownership; government takeover or nationalization of business; and government mandated price controls.

Any one or more of the above factors could adversely affect our international operations and could significantly affect our financial condition and results of operations. For example, Chinese government agencies have in the past required companies to reduce or suspend manufacturing operations from time to time, with little or no notice, for reasons such as energy restrictions and air quality concerns. The timing and length of these suspensions, which are expected to continue occurring, are difficult to predict. These unpredictable events could negatively impact our results of operations and cash flows. Further, any of these factors may impact our customers' non-U.S. operations, which could reduce demand for our products. As our



international operations and activities expand, we inevitably have greater exposure to the risks associated with operating in many foreign countries.

## Legal and Regulatory Risks

From time to time, we may be engaged in legal actions associated with our intellectual property rights; if we are unsuccessful, these could potentially result in an adverse effect on our 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. See “Intellectual Property” included within Part I. Item 1 of this Form 10-K for more information on the 844 Patent. We endeavor to protect our intellectual property rights in key jurisdictions in which our products are produced or used, in jurisdictions into which our products are imported, and in jurisdictions where our competitors have significant manufacturing capabilities. Our success will depend to a significant degree upon our ability to protect and preserve our intellectual property rights. However, we may be unable to obtain or maintain protection for our intellectual property in key jurisdictions and the Company’s patents and other intellectual property may not prevent competitors from independently developing or selling similar or duplicative products and services. Although we own and have applied for numerous patents and trademarks throughout the world, 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. We are currently involved in several legal actions relative to the intellectual property associated with the 844 Patent. On September 15, 2021, a jury in the lawsuit filed by the Company against BASF Corporation for patent infringement in the U.S. District Court for the District of Delaware (the “Delaware Proceeding”) issued a verdict in favor of BASF on certain counterclaims filed by BASF in the Delaware Proceeding. The jury awarded BASF damages of approximately $28.3 million, which will be trebled under U.S. antitrust law to approximately $85.0 million when the court enters judgment. On May 18, 2023, the court in the Delaware Proceeding entered judgment on the jury’s verdict, which commenced the post-trial briefing stage. On February 13, 2024, the court in the Delaware Proceeding denied BASF’s motion for pre-judgment interest on its tortious interference claim as well as and our motion seeking judgment as a matter of law, or a new trial in the alternative. In addition, BASF may seek post-judgment interest and attorneys’ fees and costs in amounts that they will have to prove at a future date. Earlier in the Delaware Proceeding, the U.S. District Court dismissed the Company’s patent infringement claims against BASF alleging BASF infringed the 844 Patent and invalidated some, but not all, of the claims in our 844 patent, which expired in March 2022.

The Company disagrees with the verdict, including the court’s application of the law and entry of judgment, and intends to appeal. The Company also intends to challenge the U.S. District Court’s previous dismissal of the Company’s patent infringement claims against BASF in the Delaware Proceedings. The final resolution of these matters could take up to twenty-four months and there can be no assurance that the Company will prevail in its attempts to challenge the verdict. Because the outcome of the Company’s post-trial motions and possible appeal is difficult to predict, as of December 31, 2023, the Company has accrued a total of $85.0 million, the full amount of the jury’s verdict (including treble damages). The amount accrued for this matter is included within Other liabilities on the consolidated balance sheet as of December 31, 2023, and the charge is included within Other (income) expense, net on the consolidated statement of operations for the twelve months ended December 31, 2021. The amount of any liability the Company may ultimately incur related to the Delaware Proceeding could be more or less than the amount accrued. The Company has and may continue to incur additional fees, costs and expenses for as long as the post-trial motions and possible appeal are ongoing. If the Company is required to pay the entire jury verdict (together with any associated fees, costs, and expenses), or the Company must make certain changes to its business when the matters associated with the Delaware Proceeding are eventually resolved, such outcomes could have an adverse effect on the Company’s business, financial condition, and operating results.

The Delaware Proceeding and other legal actions to protect, defend or enforce our intellectual property rights 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, which could have an adverse effect on our 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. If the Company is found to infringe any third-party rights, it could be required to pay substantial damages, or it could be enjoined from offering some of its products and services.

We also rely heavily upon unpatented proprietary technology, know-how, and other trade secrets to maintain our competitive position. While we maintain policies to enter into confidentiality agreements with our employees and third parties to protect our proprietary expertise and other trade secrets, these agreements may not be enforceable or, even if legally



enforceable, we may not have adequate remedies for breaches of such agreements. We also may not be able to readily detect breaches of such agreements. For instance, we manufacture some of our products in China where we may be at a greater risk of a third party misappropriating our intellectual property despite the foregoing policies, procedures and agreements. The failure of our patents or confidentiality agreements to protect our proprietary technology, know-how or trade secrets could result in significantly lower revenues, reduced profit margins, or loss of market share.

## Environmental and Sustainability Risks

Certain elements of our strategic growth are dependent on the adoption of more stringent air quality standards around the world.

Environmental standards drive the implementation of gasoline vapor emission control systems by automotive manufacturers. Given increasing societal concern over global warming and health hazards associated with poor air quality, there is growing pressure on regulators across the globe to take meaningful action. For those countries that have not significantly regulated gasoline vapor emissions, enacting more stringent regulations governing gasoline vapor emissions represents a significant upside to our Performance Materials' automotive carbon business. However, regulators may react to a variety of considerations, including economic and political, that may result in any such more stringent regulations being delayed or shelved entirely, in one or more countries or regions. As the adoption of more stringent regulations governing gasoline vapor emissions is expected to drive significant growth in our automotive carbon applications, the failure to enact such regulations will have an impact on the growth prospects for these products.

Our business involves hazards associated with chemical manufacturing, storage, transportation and disposal; the legal and regulatory environment related to such chemicals and other environmental impacts (such as climate change and extreme weather) could require expenditures or changes to our product formulations and operations.

There are hazards associated with the chemicals we manufacture and the related storage and transportation of our raw materials, including common solvents, such as toluene and methanol, and reactive chemicals, such as acrylic acid, all of which fall under the OSHA Process Safety Management Code. These hazards could lead to an interruption or suspension of operations and 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 and performance by third parties, and as a result we could face potential hazards, including the following: 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 adversely to us, or there is an associated economic impact on our business, we may have inadequate insurance or cash flow to offset any associated costs.

Increasing weather-related impacts on our operations and plant sites may impact the cost or availability of insurance. Furthermore, the potential impact of climate change and related regulations on our suppliers and customers is highly uncertain and there can be no assurance that it will not have an adverse effect on the availability over time of our suppliers' and customers' businesses, and on our financial condition and results of operations.

Our operations are subject to a wide range of general and industry-specific environmental laws and regulations; changes to this legal and regulatory landscape could limit our business activities and increase our operating costs.

Our operations are subject to a wide range of general and industry-specific environmental laws and regulations. Certain regulations applicable to our operations, including the OSHA and the TSCA in the U.S. and the REACH directive in Europe, the United Kingdom and other countries, prescribe limits restricting exposure to several chemicals used in our operations, including certain forms of formaldehyde, a raw material used in the manufacture of some lignin-based dispersants. Future studies on the health effects of chemicals used in our operations may result in additional regulation or new requirements, which might further restrict or prohibit the use of, and exposure to, these chemicals. Additional regulation of or requirements for such chemicals could require us to change our operations, and these changes could affect the quality or types of products we manufacture and/or materially increase our costs.

Increased focus by governmental entities on environmental issues and sustainability may result in new or increased regulations. Changes in environmental laws and regulations, or their application, could subject Ingevity to significant additional



capital expenditures and operating expenses in future years. Additionally, changes in the regulation of greenhouse gases, as well as future climate change laws and regulations, depending on their nature and scope, could subject our operations to significant additional costs or limits on operations. Our manufacturing facilities use energy, including electricity and natural gas and some of our plants emit amounts of greenhouse gas that may in the future be affected by legislative and regulatory efforts to limit greenhouse gas emissions. Potential consequences could include increased energy, transportation, and raw material costs and may require us to make additional investments in facilities and equipment or limit our ability to grow. Any such changes are uncertain and, therefore, it is not possible for Ingevity to predict with certainty the amount of additional capital expenditures or operating expenses that could be necessary for compliance with respect to any such changes.

Independent of any such regulation, increased public awareness and adverse publicity about potential impacts on climate change or environmental harm from us or our industry could harm our reputation or otherwise impact Ingevity adversely. In recent years, investors have also begun to show increased interest about sustainability and climate change as it relates to their investment decisions. We have set targets for greenhouse gas reductions and related sustainability goals. There can be no assurance that we will meet these targets and goals. If we fail to achieve our sustainability goals or reduce our impact on the environment or if we are unable to respond or are perceived to be inadequately responding to sustainability concerns, we may receive adverse publicity, and certain investors may divert from, or avoid investing in, our securities, which could have a negative impact on our business and reputation.

## Financial and Economic Risks

## We may be adversely affected by general global economic and financial conditions beyond our control.

Our businesses may be affected by a number of factors that are beyond our control such as general economic and business conditions, changes in tax laws, or tax rates and conditions in the financial services markets including counterparty risk, insurance carrier risk, rising interest rates, inflation, deflation, fluctuations in currencies, which factors may negatively impact our ability to compete. Macroeconomic challenges, including conditions in financial and capital markets and levels of unemployment, and the ability of the U.S. and other countries to deal with their rising debt levels, may continue to put pressure on the economy or lead to changes in tax laws or tax rates. There can be no assurance that changes in tax laws or tax rates will not have a material impact on our future cash taxes, effective tax rate, or deferred tax assets and liabilities. Adverse developments in global or regional economies could drive an increase or decrease in the demand for our products that could increase or decrease our revenues, increase or decrease our manufacturing costs, and ultimately increase or decrease our results of operations, financial condition and cash flows. As a result of negative changes in the economy, customers, vendors, or counterparties may experience significant cash flow problems or cause consumers of our products to postpone or refrain from spending in response to adverse economic events or conditions. If customers are not successful in generating sufficient revenue or cash flows or are precluded from securing financing, they may not be able to pay or may delay payment of accounts receivable that are owed to us or we may experience lower sales volumes. Our financial condition and results of operations could be materially and adversely affected by any of the foregoing.

## Inflation could result in an adverse impact on our results of operations.

We are affected by general global economic and financial conditions that are beyond our control, including inflation and significant spikes in energy costs. We attempt to reduce our inflation risk and mitigate the effects of other adverse economic and financial conditions by passing on price increases where appropriate to our customers. A significant portion of our business with our customers is purchase order based, which allows us to increase prices in response to inflation and other market conditions. However, to the extent our customers are under fixed-price contracts with limited or no price adjustment mechanisms, we are unable to mitigate the impact of inflation by passing on price increases through to our customers, and we could experience an adverse impact on our results of operations as a result.

## Challenges in the commercial and credit environment may materially adversely affect Ingevity’s future access to capital.

We have, at times, relied on various forms of credit to satisfy working capital needs. Our ability to issue debt or enter into other financing arrangements on acceptable terms could be materially adversely affected if there is a material decline in the demand for our products or in the solvency of our customers or suppliers or if other significantly unfavorable changes in economic conditions occur. Volatility in the world financial markets could increase borrowing costs or affect our ability to gain access to the capital markets, which could have a material adverse effect on our competitive position, business, financial condition, results of operations, and cash flows.



## ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

## ITEM 1C. CYBERSECURITY

At Ingevity, we recognize the paramount importance of cybersecurity in safeguarding sensitive information. We are aligned with industry standards, such as the ISO 27001 cybersecurity framework. Our comprehensive cybersecurity program is led by a team of diverse, highly skilled professionals, and we invest in modern technologies, including artificial intelligence and machine learning, to fortify our defenses. We continue to collaborate with local, state and federal agencies and peers in the chemical manufacturing industry to identify the latest threats and implement effective defenses to protect our employees and customers.

## Key Components of Our Cybersecurity Program:

Leadership and Governance. Led by our Chief Information Security Officer ("CISO"), we have a team of skilled internal and external cybersecurity professionals. Our Board of Directors ("the Board") has oversight of our cybersecurity and risk management programs. The Board receives at least semiannual updates from the Chief Information Officer and CISO on cybersecurity matters and our risk management program, and periodic updates from external cybersecurity experts on the overall risk landscape. We have implemented processes for continual monitoring of our information systems, including the deployment of advanced security measures and system audits to identify potential vulnerabilities. If a cybersecurity incident were to occur, we are equipped with an incident response plan that includes immediate actions to mitigate the impact and long-term strategies for remediation and prevention of future incidents. Additionally, our cybersecurity team regularly meets with our executive management leadership team to provide updates on our cybersecurity risks and incidents ensuring management is keenly aware of any potential threat.

Protection of Sensitive Information. We maintain collection, storage, and access controls of personal, proprietary, and confidential information, focusing on protecting trade secrets, intellectual property, clinical trial data, third-party information, and employee data.

Industry-Standard Frameworks and Policies. We incorporate industry-standard frameworks, policies, and practices such as ISO 27001 which are designed to protect the confidentiality and privacy of information.

Protection Mechanisms. We currently follow the ISO 27001 cybersecurity framework and are progressing toward program certification. We continuously monitor our enterprise network and have deployed detective and preventative controls. In-depth third-party security assessments are conducted annually.

Incident Response and Testing. We have a robust cybersecurity incident response plan that incorporates regular simulations, drills, and vulnerability scans, penetration testing and third-party assessments of our cybersecurity controls and resilience.

Third-Party Monitoring. We employ a managed security services provider that provides 24/7 monitoring of our enterprise network. We require third-party service providers with access to personal, confidential or proprietary information to implement and maintain comprehensive cybersecurity practices consistent with applicable legal standards and industry best practices.

Insurance Coverage. We maintain insurance coverage that includes cybersecurity protection.

Our proactive approach to cybersecurity involves the integration of leading technologies and collaboration with third-party experts to ensure alignment with industry standards. We believe these measures contribute to the protection of both our organization's and our clients' sensitive information.

During the past year, there have been no material risks from cybersecurity threats or prior cybersecurity incidents that have materially affected or are reasonably likely to materially affect the Company’s business strategy, results of operations, or financial condition. Despite our security architecture and controls, and those of our third-party providers, we may be vulnerable to cyber-attacks, computer viruses, security breaches, ransomware attacks, inadvertent or intentional employee actions, system failures, and other risks that could materially impact our financial results and our results of operations.

## ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

## Introduction

Management’s discussion and analysis of Ingevity’s financial condition and results of operations (“MD&A”) should be read in conjunction with Item 8. Financial Statements and Supplementary Data. Investors are cautioned that the forward-looking statements contained in this section and other parts of this Annual Report on Form 10-K involve both risk and



uncertainty. Several important factors could cause actual results to differ materially from those anticipated by these statements. Many of these statements are macroeconomic in nature and are, therefore, beyond the control of management. See "Cautionary Statements about Forward-Looking Statements" at the beginning of this Annual Report on Form 10-K for further discussion.

## Overview

Ingevity Corporation ("Ingevity," "the company," "we," "us," or "our") provides products and technologies that purify, protect, and enhance the world around us. Through a diverse team of talented and experienced people, we develop, manufacture, and bring to market solutions that are largely renewably sourced and help customers solve complex problems while making the world more sustainable. Our products are used in a variety of demanding applications, including adhesives, agrochemicals, asphalt paving, bioplastics, coatings, elastomers, lubricants, pavement markings, publication inks, oil exploration and production, and automotive components. We operate in three reporting segments: Performance Materials, Performance Chemicals, and Advanced Polymer Technologies.

Our Performance Materials segment manufactures products in the form of powder, granular, extruded pellets, extruded honeycombs, and activated carbon sheets. Performance Materials engineers, manufactures, and sells hardwood-based, chemically activated carbon products which are produced through a highly technical and specialized process primarily for use in gasoline vapor emission control systems in internal combustion engines and hybrid electric vehicles including cars, trucks, motorcycles, and boats. To maximize the productivity of our manufacturing assets, we also produce several other activated carbon products for food, water, beverage, and chemical purification applications.

Our Performance Chemicals segment consists of our road technologies (previously named pavement technologies) and industrial specialties product lines. Performance Chemicals products serve as critical inputs used in a variety of high-performance applications, including pavement construction, pavement preservation, pavement reconstruction and recycling, road markings (road technologies product line), as well as agrochemical dispersants, paper chemicals, and other diverse industrial uses (industrial specialties product line).

Our Advanced Polymer Technologies segment produces caprolactone and caprolactone-based specialty polymers for use in coatings, resins, elastomers, adhesives, bioplastics, and medical devices.

## Recent Developments

## Restructuring Charges

## Performance Chemicals Repositioning

Throughout 2023 we initiated several measures across the organization to pursue greater cost efficiency which included a reorganization to streamline certain functions and reduce ongoing costs. On November 1, 2023, we announced a number of strategic actions designed to further reposition our Performance Chemicals operating segment to improve the profitability and reduce the cyclicality of the Company as a whole. These actions increase our focus on growing our most profitable Performance Chemicals product lines such as road technologies and accelerate our transition to non-crude tall oil (“CTO”)-based fatty acids. The announced actions include the permanent closure of our Performance Chemicals’ CTO refinery and the closure of our manufacturing plant located in DeRidder, Louisiana (the “DeRidder Plant”), including the polyol production assets associated with the Advance Polymer Technologies reportable segment, as well as additional corporate and business cost reduction actions. We expect to close the DeRidder Plant by the end of the first half of 2024.

We expect to incur aggregate charges of approximately $280.0 million associated with these actions, consisting of approximately $180.0 million in asset-related charges, approximately $15.0 million in severance and other employee-related costs, and approximately $85.0 million in other restructuring costs including decommissioning, dismantling and removal charges, and contract termination costs. We expect approximately $180.0 million of the total charges to be non-cash. The majority of non-cash charges and 50-60 percent of cash charges are expected to be recognized in 2024. Excluded from the $280.0 million of estimated aggregate charges are potential costs we may incur associated with excess volumes of CTO that we may be obligated to purchase through October 2025 under an existing CTO supply contract. We intend to manage our CTO inventories by reselling excess volumes in the open market which, based on what we believe to be market rates today, may result in $30.0 million to $80.0 million of incremental losses in 2024.

During the year ended December 31, 2023, we incurred $5.1 million in cash charges and $127.7 million in non-cash charges related to the strategic actions initiated during the fourth quarter of 2023.



The charges we currently expect to incur in connection with these actions are subject to a number of assumptions and risks, and actual results may differ materially. We may also incur other material charges not currently contemplated due to events that may occur as a result of, or in connection with, these actions.

## Alternative Fatty Acid Transition

In April 2023, we implemented the feedstock transition of our Crossett, Arkansas manufacturing plant (“Crossett”). To execute this transition, we halted all CTO-based production at Crossett in April. This transition converted Crossett from a CTO-based feedstock production facility to produce fatty acids from non-CTO plant-based feedstocks. During the year ended December 31, 2023, we incurred $22.1 million in costs that, in accordance with GAAP, could not be capitalized.

## North Charleston Plant Transition

Our North Charleston, South Carolina Performance Chemicals manufacturing plant has historically been co-located with a WestRock Company (“WestRock”) paper mill. In May 2023, WestRock announced that it would permanently cease operating its North Charleston paper mill by August 31, 2023 and notified us that it was terminating the shared services in accordance with our operating agreement. WestRock ceased production at their North Charleston paper mill in June 2023. During 2023, we executed a transition plan to separate certain critical operating services WestRock had historically provided to us such as steam, water and wastewater treatment. During the year ended December 31, 2023, we incurred $14.8 million of expense. We expect to incur an additional $3-5 million of costs as we complete this transition in the first half of 2024.

## Supply Agreements

On March 20, 2023, Ingevity and WestRock Shared Services, LLC and WestRock MWV, LLC, on behalf of the affiliates of WestRock Company (“WestRock”), entered into an amended and restated crude tall oil and black liquor soap skimmings agreement, which amends and restates that certain crude tall oil and black liquor soap skimmings agreement, dated as of January 1, 2016, by and between Ingevity and WestRock, as amended by that Amendment No.1 to Crude Tall Oil And Black Liquor Soap Skimmings Agreement, dated as of March 1, 2017, and Amendment No.2 to Crude Tall Oil And Black Liquor Soap Skimmings Agreement, dated as of November 3, 2020.

On November 1, 2023, Ingevity Corporation and WestRock entered into Amendment No.1 to that certain Amended and Restated Crude Tall Oil and Black Liquor Soap Skimmings Agreement, dated as of March 20, 2023, by and between the Company and WestRock.

On March 21, 2023, Ingevity, Georgia-Pacific LLC, on behalf of itself and its subsidiaries (“Georgia-Pacific”), and GP Pine Chemicals LLC, a direct subsidiary of Georgia-Pacific LLC, entered into a Second Amendment to the Crude Tall Oil Supply Agreement, to amend certain terms of the Crude Tall Oil Supply Agreement, dated as of March 9, 2018, by and between Ingevity and Georgia-Pacific, as amended by that Amendment to the Crude Tall Oil Supply Agreement, dated as of May 1, 2020.

## Performance Chemicals Reporting Unit

During the third quarter of 2023, continued reduction in demand in industrial end markets had negatively impacted our ability to offset elevated CTO costs through pricing actions within our Performance Chemicals' reportable segment, particularly in our industrial specialties product line. CTO is essential to our industrial specialties and some of our road technologies product lines within our Performance Chemicals reportable segment. As a result, we concluded that a triggering event occurred for our Performance Chemicals' reporting unit, and we performed an analysis of the reporting unit's goodwill, intangibles and long-lived assets as of September 1, 2023. Our analysis included significant assumptions such as: revenue growth rate, Earnings before Interest, Taxes, Depreciation and Amortization ("EBITDA") margin, and discount rate which are judgmental and variations in any assumptions could result in materially different calculations of fair value. We concluded that there was no impairment for the quarter ended September 30, 2023.

Our fiscal year 2023 annual goodwill impairment test was performed as of October 1, 2023. We determined that the fair value of our reporting units were in excess of their carrying value and therefore concluded that no goodwill impairment existed. There were no events or circumstances indicating that goodwill might be impaired as of December 31, 2023.



## Segment Change

During the first quarter of 2023, we realigned our segment reporting structure to increase transparency for our investors and better align with how our chief operating decision maker intends to measure segment operating performance and allocate resources across our operating segments. Effective in the first quarter of 2023, we separated our engineered polymers product line from the Performance Chemicals reportable segment into its own reportable segment, Advanced Polymer Technologies. This reportable segment change also resulted in our Performance Chemicals reporting unit for goodwill being split into two separate reporting units for the purposes of goodwill impairment testing. This reportable segment change has no impact on our consolidated operating results or the historical operating results of our Performance Materials operating segment.

## Equity Method Investment

During the first quarter of 2023, we sold a strategic equity method investment for $31.5 million, resulting in a $19.3 million gain, recorded within "Other (income) expense, net" on the consolidated statement of operations.

## Net sales

The table below shows 2023 and 2022 Net sales and variances from 2022 and 2021, respectively.

<table><tr><td rowspan="2">In millions</td><td rowspan="2">Prior year Net sales</td><td colspan="4">Change vs. prior year</td></tr><tr><td>Volume</td><td>Price/Mix</td><td>Currency effect</td><td>Current year Net sales</td></tr><tr><td>Year Ended December 31, 2023 vs. 2022</td><td>$ 1,668.3</td><td>(106.3)</td><td>142.3</td><td>(12.2)</td><td>$ 1,692.1</td></tr><tr><td>Year Ended December 31, 2022 vs. 2021</td><td>$ 1,391.5</td><td>9.4</td><td>294.2</td><td>(26.8)</td><td>$ 1,668.3</td></tr></table>

## Year Ended December 31, 2023 vs. 2022

The sales increase in 2023 was driven by favorable pricing and sales composition (mix) of $142.3 million (nine percent), primarily attributed to an increase in Performance Chemicals of $93.1 million, partially offset by volume decline of $106.3 million (six percent), and unfavorable foreign exchange impacts of $12.2 million (one percent).



## Year Ended December 31, 2022 vs. 2021

The sales increase in 2022 was driven by favorable pricing and sales composition (mix) of $294.2 million (21 percent), primarily attributed to an increase in Performance Chemicals of $216.9 million, and a volume increase of $9.4 million (one percent), offset slightly by unfavorable foreign exchange impacts of $26.8 million (two percent).

## Gross profit

## Year Ended December 31, 2023 vs. 2022

Gross profit decrease of $98.2 million was driven by increased manufacturing costs of $158.6 million due primarily to significant CTO raw material cost pressure within our industrial specialties product line in our Performance Chemicals reportable segment, unfavorable sales volume of $46.9 million, inventory charges of $19.7 million and unfavorable foreign exchange impacts of $0.9 million, partially offset by favorable pricing and sales composition (mix) of $127.9 million. Refer to the Segment Operating Results section included within this MD&A for more information on the drivers of the changes in gross profit period over period for both segments.

## Year Ended December 31, 2022 vs. 2021

Gross profit increase of $57.3 million was driven by favorable pricing and sales composition (mix) of $291.5 million, and favorable sales volume of $6.3 million, partially offset by increased manufacturing costs of $238.0 million primarily due to raw material and energy cost inflationary pressure, and unfavorable foreign currency exchange of $2.5 million. Refer to the Segment Operating Results section included within this MD&A for more information on the drivers to the changes in gross profit period over period for both segments.

## Selling, general, and administrative expenses

## Year Ended December 31, 2023 vs. 2022

Selling, general, and administrative ("SG&A") expenses were $183.7 million (11 percent of Net sales) and $198.8 million (12 percent of Net sales) for the years ended December 31, 2023 and 2022, respectively. The decrease in SG&A expenses is primarily due to lower employee-related costs of $18.4 million, and decreased travel and other miscellaneous costs of $6.9 million, partially offset by increased amortization expense of $10.2 million due to the Ozark Materials acquisition.

## Year Ended December 31, 2022 vs. 2021

SG&A expenses were $198.8 million (12 percent of Net sales) and $179.3 million (13 percent of Net sales) for the years ended December 31, 2022 and 2021, respectively. The increase in SG&A expenses is primarily due to higher employee-related costs of $11.3 million and increased travel and other miscellaneous costs of $10.6 million. This was partially offset by a decrease in litigation defense costs of $2.4 million.

## Research and technical expenses

## Years Ended December 31, 2023, 2022, and 2021

Research and technical expenses as a percentage of Net sales remained relatively consistent period over period, totaling 1.9 percent of sales in the year ended December 31, 2023, compared to 1.8 percent in the year ended December 31, 2022, and 1.9 percent in the year ended December 31, 2021.

## Restructuring and other (income) charges, net

## Years Ended December 31, 2023, 2022, and 2021

Restructuring and other (income) charges, net, were $170.2 million, $13.8 million, and $16.2 million for the years ended December 31, 2023, 2022, and 2021, respectively. For the year ended December 31, 2023, asset disposal charges were $105.6 million, severance and other employee-related costs were $18.4 million, and other restructuring charges were $1.6 million. Additionally, alternative fatty acid transition costs were $22.1 million, costs associated with the North Charleston plant transition were $14.8 million, and costs related to our digital transformation initiative were $7.7 million. For the years ended December 31, 2022 and 2021, the majority of the charges were related to our digital transformation initiative.

## Segment Operating Results

In addition to the information discussed above, the following sections discuss the results of operations for each of Ingevity's segments. Our segments are (i) Performance Materials, (ii) Performance Chemicals, and (iii) Advanced Polymer Technologies. Segment Earnings before Interest, Taxes, Depreciation and Amortization ("EBITDA") is the primary measure used by the Company's chief operating decision maker to evaluate the performance of and allocate resources among our operating segments. Segment EBITDA is defined as segment net sales less segment operating expenses (segment operating expenses consist of costs of sales, selling, general and administrative expenses, other (income) expense, net, excluding depreciation and amortization). We have excluded the following items from segment EBITDA: interest expense, net, associated with corporate debt facilities, income taxes, depreciation, amortization, restructuring and other (income) charges, net, including inventory lower of cost or market charges associated with restructuring actions, acquisition and other-related (income) costs, litigation verdict charges, (losses) gains from the sale of strategic investments, (losses) gains on CTO resales, and pension and postretirement settlement and curtailment (income) charge, net. In general, the accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies in Note 2 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K.

## Performance Materials

## Performance Summary

Our Performance Materials segment experienced solid automotive volume growth from improved semiconductor chip availability and China automobile production stimulus. The segment also recognized volume improvement in food, water, beverage, and chemical purification products and we were able to increase prices to capture more of the value from our highly differentiated carbon. These top-line improvements were largely offset by continued pressure from higher raw material input costs and higher logistic costs driven by inflation. The strengthening of the U.S. dollar against the Chinese renminbi and the euro also contributed to the pressure on EBITDA when compared to the prior year.

Segment EBITDA increased by $34.4 million due to pricing and sales composition (mix) of $21.1 million, decreased SG&A expenses and research and technical costs of $11.6 million, and favorable volume of $10.9 million. The increase was partially offset by higher manufacturing costs of $8.8 million, and unfavorable foreign currency exchange impacts of $0.4 million.



## Year Ended December 31, 2022 vs. 2021

Segment net sales. The increase in 2022 was driven by a volume increase of $28.6 million (six percent) and favorable pricing of $14.9 million (three percent), partially offset by unfavorable foreign currency exchange impacts of $11.8 million (two percent).

Segment EBITDA. Segment EBITDA increased by $2.8 million due to favorable volume of $15.6 million, pricing and sales composition (mix) of $13.8 million, and decreased SG&A expenses and research and technical costs of $0.5 million. The increase was largely offset by higher manufacturing costs of $21.5 million, and unfavorable foreign currency exchange impacts of $5.6 million.

## Performance Chemicals

## Performance Summary

Our Performance Chemicals segment grew revenue versus the prior year on continued price improvement and favorable mix upgrade to higher margin products. These price increases were necessary to keep pace with the inflationary increases related to raw material, energy, and logistic costs.

Road Technologies sales increased by 53.3 percent due primarily to improved volumes and price increases. Volume growth was driven by technology adoption and highway funding in the United States, as well as the acquisition of Ozark Materials.

Industrial Specialties sales decreased by 16.0 percent driven by volume declines attributed primarily to weak demand across all end markets, particularly adhesives and printing inks.

Year Ended December 31, 2023 vs. 2022

Segment net sales. The sales increase was driven by favorable pricing and sales composition (mix) of $93.1 million (11 percent), comprised of industrial specialties ($62.7 million) and road technologies product lines ($30.4 million), respectively. The increase was partially offset by a volume decrease of $65.3 million (seven percent), driven by a decline in industrial specialties ($167.7 million), partially offset by growth in road technologies ($102.4 million). Unfavorable foreign currency exchange also impacted Net sales by $0.8 million (zero percent).

Segment EBITDA. Segment EBITDA decreased $94.7 million, mainly due to higher manufacturing costs of $157.8 million primarily due to increased CTO cost, a volume decline of $34.1 million, and unfavorable foreign currency exchange of $0.1 million. These increases were partially offset by favorable pricing and sales composition (mix) of $89.7 million and decreased SG&A expenses of $7.6 million.

Segment net sales. The sales increase was driven by favorable pricing and product mix of $216.9 million (31 percent) in industrial specialties ($201.8 million) and road technologies product lines ($15.1 million), partially offset by a volume decline of $26.1 million (four percent), and unfavorable foreign currency exchange impacting Net sales by $4.6 million (one percent).

Segment EBITDA. Segment EBITDA increased $19.9 million, mainly due to favorable pricing and product mix of $217.8 million, and favorable foreign currency exchange impacts and other miscellaneous charges of $1.6 million. These increases were partially offset by higher manufacturing costs of $167.5 million due to inflationary raw material and energy costs, increased SG&A expenses of $20.0 million due to increased spending on growth initiatives, compensation, and travel, and volume decline of $12.0 million.

## Advanced Polymer Technologies

## Performance Summary

Our Advanced Polymer Technologies segment sales decreased compared to the prior year due to market weakness across the segment's end markets in all regions, partially offset by higher prices. Segment EBITDA increase was driven primarily by profit recovery initiatives, including pricing actions and product mix management, and lower input costs.

## Use of Non-GAAP Financial Measures

Inevency has presented the financial measure, Adjusted EBITDA, defined below, which has not been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and has provided a reconciliation to net income, the most directly comparable financial measure calculated in accordance with GAAP. Adjusted EBITDA is not meant to be considered in isolation nor as a substitute for the most directly comparable financial measure calculated in accordance with GAAP. Adjusted EBITDA is utilized by management as a measure of profitability.

We believe this non-GAAP financial measure provides management as well as investors, potential investors, securities analysts, and others with useful information to evaluate the performance of the business, because such measure, when viewed together with our financial results computed in accordance with GAAP, provides a more complete understanding of the factors and trends affecting our historical financial performance and projected future results. We believe Adjusted EBITDA is a useful measure because it excludes the effects of financing and investment activities as well as non-operating activities.

Adjusted EBITDA is defined as net income (loss) plus interest expense, net, provision (benefit) for income taxes, depreciation, amortization, restructuring and other (income) charges, net, including inventory lower of cost or market charges associated with restructuring actions, acquisition and other-related (income) costs, litigation verdict charges, gain on sale of strategic investments, loss on CTO resales, and pension and postretirement settlement and curtailment (income) charges, net.

This non-GAAP measure is not intended to replace the presentation of financial results in accordance with GAAP and investors should consider the limitations associated with these non-GAAP measures, including the potential lack of comparability of these measures from one company to another. A reconciliation of Adjusted EBITDA to net income is set forth within this section.

(1) We regularly perform strategic reviews and assess the return on our operations, which sometimes results in a plan to restructure the business. These costs are excluded from our reportable segment results and for the purposes of calculating our non-GAAP financial performance measures. Additionally, this adjustment includes $19.7 million of inventory charges recorded in Cost of sales on our consolidated statement of operations, associated with the repositioning of our Performance Chemicals segment in the year ended December 31, 2023. Refer to Note 15 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information on the charges.

(2) Charges represent costs incurred to complete and integrate acquisitions and other strategic investments and include the expensing of the inventory fair value step-up resulting from the application of purchase accounting for acquisitions and certain legal and professional fees.



associated with the completion of acquisitions and strategic investments. Refer to Note 16 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information.

(3) Due to the DeRidder Plant closure, as noted in footnote 1 above, and the corresponding reduced CTO refining capacity, we may be obligated, under an existing CTO supply contract, to purchase CTO through 2025 at amounts in excess of required CTO volumes. We intend to manage our CTO volumes by reselling excess volumes (herein referred to as "CTO resales") in the open market. Since these CTO resale activities are directly attributable to the Performance Chemicals' repositioning, that is, they do not represent normal, recurring expenses necessary to operate our business, we have excluded the CTO resale (income) charges for the purposes of calculating our non-GAAP financial performance measures. For the year ended December 31, 2023, the loss on CTO resales relates to the Performance Chemicals segment. Refer to Note 2 and Note 15 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information.

(4) We exclude gains and losses from sales of strategic investments from our segment results, as well as our non-GAAP financial measures, because we do not consider such gains or losses to be directly associated with the operational performance of the segment. We believe that the inclusion of such gains or losses, would impair the factors and trends affecting the historical financial performance of our reportable segments. We continue to include undistributed earnings or loss, distributions, amortization or accretion of basis differences, and other-than-temporary impairments for equity method investments that we believe are directly attributable to the operational performance of such investments, in our reportable segment results. Refer to Note 5 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information.

(5) For the year ended December 31, 2021, litigation verdict charge relates to the Performance Materials segment. Refer to Note 18 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information.

(6) Our pension and postretirement settlement and curtailment charges (income) are related to the acceleration of prior service costs, as a result of a reduction in the number of participants within the Union Hourly defined benefit pension plan. These are excluded from our segment results because we consider these costs to be outside our operational performance. We continue to include the service cost, amortization of prior service cost, interest costs, expected return on plan assets, and amortized actual gains and losses in our segment EBITDA. Refer to Note 14 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information.

## Adjusted EBITDA

## Year Ended December 31, 2023, 2022 and 2021

The factors that impacted Adjusted EBITDA period to period are the same factors that affected earnings discussed in the sections entitled "Results of Operations" and "Segment Operating Results" within MD&A.

## Current Full Year Company Outlook vs. Prior Year

Net sales are expected to be between $1.40 billion and $1.55 billion for 2024. We expect growth in our Performance Materials reportable segment on improved global automotive production over the prior year. While our Performance Chemicals reportable segment revenue will reflect the impact of our Performance Chemicals repositioning, including the exit of certain low-margin businesses in our Industrial Specialties product line, we expect continued growth from our Road Technology product line due to technology adoption and continued geographic expansion. Our Advanced Polymer Technologies reportable segment is expected to see demand rebound in industrial markets in the second half of the year as well as growth from their sustainable products in the consumer packing, agriculture chemicals, and apparel end-use markets.

Adjusted EBITDA is expected to be between $365 million and $390 million for 2024. We expect growth in our Performance Materials EBITDA, as volumes shift to higher-margin automotive carbon due to improved global automotive production and ongoing hybrid vehicle adoption. In Performance Chemicals, we will have less exposure to certain lower-margin businesses in the Industrial Specialties product line due to the repositioning of the segment, and we expect to see continued growth in our Road Technologies product line. Performance Chemicals will continue to be impacted by elevated CTO costs, which we expect to abate in the second half of the year. We anticipate improved Advanced Polymer Technologies EBITDA on a combination of increased volumes and favorable manufacturing throughput.

A reconciliation of net income to adjusted EBITDA as projected for 2024 is not provided. Ingevity does not forecast net income as it cannot, without unreasonable effort, estimate or predict with certainty various components of net income. These components, net of tax, include further restructuring and other income (charges), net; additional acquisition and other-related income (costs); litigation verdict charges; additional pension and postretirement settlement and curtailment (income) charges; and revisions due to legislative tax rate changes. Additionally, discrete tax items could drive variability in our projected effective tax rate. All of these components could significantly impact such financial measures. Further, in the future, other items with similar characteristics to those currently included in adjusted EBITDA, that have a similar impact on comparability of periods, and which are not known at this time, may exist and impact adjusted EBITDA.



## Liquidity and Capital Resources

The primary source of liquidity for our business is the cash flow provided by operating activities. We expect our cash flow provided by operations combined with cash on hand and available capacity under our revolving credit facility to be sufficient to fund our planned operations and meet our interest and other contractual obligations for at least the next twelve months. As of December 31, 2023, our undrawn capacity under our revolving credit facility was $259.5 million. Over the next twelve months, we expect to fund the following: interest payments, capital expenditures, expenditures related to our business transformation initiative, debt principal repayments, income tax payments, purchases pursuant to our stock repurchase program (and related excise tax payments), income tax payments, additional spending associated with our Performance Materials' intellectual property litigation, and restructuring activities such as the North Charleston plant transition, and the repositioning of our Performance Chemicals operating segment as further described within Note 15 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K. In addition, we may also evaluate and consider strategic acquisitions, joint ventures, or other transactions to create stockholder value and enhance financial performance. In connection with such transactions, or to fund other anticipated uses of cash, we may modify our existing revolving credit facility, redeem all or part of our outstanding senior notes, seek additional debt financing, issue equity securities, or some combination thereof.

Cash and cash equivalents totaled $95.9 million at December 31, 2023. We continuously monitor deposit concentrations and the credit quality of the financial institutions that hold our cash and cash equivalents, as well as the credit quality of our insurance providers, customers, and key suppliers.

Due to the global nature of our operations, a portion of our cash is held outside the U.S. The cash and cash equivalents balance at December 31, 2023, included $90.7 million held by our foreign subsidiaries. Cash and earnings of our foreign subsidiaries are generally used to finance our foreign operations and their capital expenditures. We believe that our foreign holdings of cash will not have a material adverse impact on our U.S. liquidity. If these earnings were distributed, such amounts would be subject to U.S. federal income tax at the statutory rate less the available foreign tax credits, if any, and would potentially be subject to withholding taxes in the various jurisdictions. The potential tax implications of the repatriation of unremitted earnings are driven by facts at the time of distribution, therefore, it is not practicable to estimate the income tax liabilities that might be incurred if such cash and earnings were repatriated to the U.S.. Management does not currently expect to repatriate cash earnings from our foreign operations in order to fund U.S. operations.

## Debt and Finance Lease Obligations

Refer to Note 10 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for a summary of our outstanding debt obligations and revolving credit facility.

## Other Potential Liquidity Needs

## Share Repurchases

On July 25, 2022, our Board of Directors authorized the repurchase of up to $500.0 million of our common stock and rescinded the prior outstanding repurchase authorization with respect to the shares that remained unused under the prior authorization. Shares under the current repurchase authorization may be purchased through open market or privately negotiated transactions at the discretion of management based on its evaluation of market prevailing conditions and other factors, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended.

During the year ended December 31, 2023, we repurchased $92.1 million in common shares (inclusive of $0.8 million in excise tax), representing 1,269,373 shares of our common stock at a weighted average cost per share of $71.93. At December 31, 2023, $353.4 million remained available for purchase under our Board-authorized repurchase program.

## Capital Expenditures

Projected 2024 capital expenditures are expected to be $90 million to $110 million. We have no material commitments associated with these projected capital expenditures as of December 31, 2023.

## Cash flows provided by (used in) operating activities

Cash provided by (used in) operating activities, which consists of net income (loss) adjusted for non-cash items including the cash impact from changes in operating assets and liabilities (i.e., working capital), totaled $205.1 million for the year ended December 31, 2023.

Cash provided by (used in) operating activities for 2023 was driven by lower cash earnings of $57.2 million and a net increase in overall working capital of $48.3 million, despite a decrease in trade working capital (accounts receivable, inventory, and accounts payable) of $15.6 million, compared to 2022. Cash flow from operations was further reduced by an increase in cash interest paid of $27.9 million due to higher average debt levels resulting from the October 2022 acquisition of Ozark Materials and rising interest rates during 2023. This was partially offset by a reduction in tax payments of $25.1 million.

Cash provided by (used in) operating activities for 2022 was driven by higher cash earnings of $41.4 million offset by a net increase in overall working capital of $12.9 million which includes an increase in trade working capital (accounts receivable, inventory, and accounts payable) of $8.3 million. The build in trade working capital was due primarily to higher end of year accounts receivable on higher sales and higher inventory value due to inflation experienced during 2022 compared to 2021. Cash flow from operations was further reduced by an increase in cash interest paid of $7.3 million primarily due to rising interest rates during 2022 compared to 2021, as well as an increase in cash tax payments of $1.1 million. The higher tax payments were driven by the higher year over year earnings offset by refunds received in 2022 on prior years' earnings.

## Cash flows provided by (used in) investing activities

For the year ended December 31, 2023, investing activities were driven by capital spending, offset partially by the proceeds from the sale of a strategic investment. Capital spending included the base maintenance capital supporting ongoing operations and cost improvement and growth spending in our Advanced Polymer Technologies segment. Also, during the year ended December 31, 2023, we sold a strategic investment (refer to Note 5 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information).

For the year ended December 31, 2022, investing activities were driven by capital spending, the Ozark Materials acquisition, and the purchase of strategic investments. Capital spending included the base maintenance capital supporting ongoing operations and cost improvement and growth spending primarily related to our business transformation initiative (refer to Note 15 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information). Also, during the year ended December 31, 2022, we acquired Ozark Materials (refer to Note 16 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information) and we entered into multiple strategic investments (refer to Note 5 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information).

## Cash flows provided by (used in) financing activities

Cash used in financing activities for the year ended December 31, 2023, was $99.9 million and was driven by share repurchases of $92.1 million, net payments on the revolving credit facility of $87.9 million, and offset by proceeds from our accounts receivable securitization facility of $81.3 million.

Cash provided by financing activities for the year ended December 31, 2022, was $48.1 million and was driven by net proceeds from the revolving credit facility of $828.0 million, offset by payments on long-term borrowings of $628.1 million, payments, and share repurchases of $145.2 million.

## New Accounting Guidance

Refer to Note 3 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for a full description of recent accounting pronouncements including the respective expected dates of adoption and expected effects on our Consolidated Financial Statements.

## Critical Accounting Policies and Estimates

Our principal accounting policies are described in Note 2 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K. Our Consolidated Financial Statements are prepared in conformity with GAAP. The preparation of our financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses. We have reviewed these accounting policies, identifying those that we believe to be critical to the preparation and understanding of our financial statements. Critical accounting policies are central to our presentation of results of operations and financial condition and require management to make estimates and judgments on certain matters. We base our estimates and judgments on historical experience, current conditions, and other reasonable factors.

The following is a list of those accounting policies that we have deemed most critical to the presentation and understanding of our results of operations and financial condition:

## Revenue recognition

Our revenue is derived from contracts with customers, and substantially all our revenue is recognized when products are either shipped from our manufacturing and warehousing facilities or delivered to the customer. Revenue, net of returns and customer incentives, is based on the sale of manufactured products. Revenues are recognized when performance obligations under the terms of a contract with our customer are satisfied; generally, this occurs with the transfer of control of our products. For certain limited contracts, where we are producing goods with no alternative use and for which we have an enforceable right to payment for performance completed to date, we are recognizing revenue as goods are manufactured, rather than when they are shipped. Revenues are presented as Net sales on the consolidated statements of operations.

Since Net sales are derived from product sales only, we have disaggregated our Net sales by our product lines within each reportable segment. Net sales are measured as the amount of consideration we expect to receive in exchange for transferring goods. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Sales returns and allowances are not a normal practice in the industry and are not significant. Certain customers may receive cash-based incentives, including discounts and volume rebates, which are accounted for as variable consideration and included within Net sales. Shipping and handling fees billed to customers are included in Net sales. If we pay for the freight and shipping, we recognize the cost when control of the product has transferred to the customer as an expense within Cost of sales on the consolidated statements of operations. Payment terms with our customers are typically in the range of zero to sixty days. Because the period between when we transfer a promised good to a customer and when the customer pays for that good will be one year or less, we elect not to adjust the promised amount of consideration for the effects of any financing component, as it is not significant.

## Valuation of tangible and intangible long-lived assets and goodwill

Our long-lived assets primarily include property, plant, and equipment, and other intangible assets. We periodically evaluate whether current events or circumstances indicate that the carrying value of long-lived assets to be held and used may not be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the long-lived asset, or the appropriate grouping of assets, is compared to carrying value to determine whether an impairment exists.



If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows. We report an asset to be disposed of at the lower of its carrying value or its estimated net realizable value.

Goodwill represents the excess of cost of an acquired business over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed in a business combination. We conduct a required annual review of goodwill for potential impairment at October 1, or sooner if events or changes in circumstances indicate that the fair value of a reporting unit is below its carrying value. Our reporting units are our operating segments, i.e., Performance Materials, Performance Chemicals and Advanced Polymer Technologies. If the carrying value of a reporting unit that includes goodwill exceeds its fair value, which is determined using both the income approach and market approach, goodwill is considered impaired. The income approach determines fair value based on discounted cash flow model derived from a reporting unit's long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to the projected earnings of the reporting unit. The amount of impairment loss is measured as the difference between the carrying value and the fair value of a reporting unit but is limited to the total amount of goodwill allocated to the reporting unit. In performing the fair value analysis, management makes various judgments, estimates, and assumptions, the most significant of which are the assumptions related to revenue growth rates, Earnings before Interest, Taxes, Depreciation and Amortization ("EBITDA") margin, and discount rate.

The factors we considered in developing our estimates and projections for cash flows include, but are not limited to, the following: (i) macroeconomic conditions; (ii) industry and market considerations; (iii) costs, such as increases in raw materials, labor, or other costs; (iv) our overall financial performance; and (v) other relevant entity-specific events that impact our reporting units.

The determination of whether goodwill is impaired involves a significant level of judgment in the assumptions underlying the approach used to determine the estimated fair values of our reporting units. We believe that the estimates and assumptions used in our impairment assessment are reasonable; however, these assumptions are judgmental and variations in any assumptions could result in materially different calculations of fair value. We will continue to evaluate goodwill on an annual basis as of October 1, and whenever events or changes in circumstances, such as significant adverse changes in operating results, market conditions, or changes in management's business strategy indicate that there may be a probable indicator of impairment. It is possible that the assumptions used by management related to the evaluation may change or that actual results may vary significantly from management's estimates.

## Business Combinations

Accounting for business combinations, which requires, among other things, the acquiring entity in a business combination to recognize the fair value of the assets acquired and liabilities assumed; the recognition of acquisition-related costs within the consolidated results of operations; the recognition of restructuring costs within the consolidated results of operations for which the acquirer becomes obligated after the acquisition date; and contingent purchase consideration to be recognized at fair value on the acquisition date with subsequent adjustments recognized on the consolidated statements of operations. We generally use qualified third-party consultants to assist management in determining the fair value of assets acquired and liabilities assumed. This includes, when necessary, assistance with the determination of lives and valuation of tangible property, plant, and equipment and identifiable intangibles, assisting management in determining the fair value of obligations associated with employee-related liabilities and assisting management in assessing obligations associated with legal and environmental claims.

The fair value assigned to identifiable intangible assets acquired is determined primarily by using an income approach, which is based on assumptions and estimates made by management. Significant assumptions utilized in the income approach are the attrition rate, revenue growth rates, EBITDA margins, royalty rates, and the discount rate. These assumptions are based on company-specific information and projections, which are not observable in the market and are therefore considered Level 2 and Level 3 measurements. The excess of the purchase price over the fair value of the identified assets and liabilities is recorded as goodwill. Based on the acquired business' end markets and products, as well as how the chief operating decision maker will review the business results, determines the most appropriate operating segment for which to integrate the acquired business. Goodwill acquired, if any, is allocated to the reporting unit within or at the operating segment for which the acquired business will be integrated. Selection of the appropriate reporting unit is based on the level at which discrete financial information is



available and reviewed by business management post-integration. Operating results of the acquired entity are reflected within the Consolidated Financial Statements from the date of acquisition.

## Income taxes

We are subject to income taxes in the U.S. and numerous foreign jurisdictions, including China and the United Kingdom. The provision for income taxes includes income taxes paid, currently payable or receivable, and deferred taxes. We follow the liability method of accounting for income taxes in accordance with current accounting standards regarding the accounting for income taxes. Under this method, deferred income taxes are recorded based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws in effect at the time the underlying assets or liabilities are recovered or settled. The ability to realize deferred tax assets is evaluated through the forecasting of taxable income, historical and projected future operating results, the reversal of existing temporary differences, and the availability of tax planning strategies. Valuation allowances are recognized to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. We do not provide income taxes on undistributed earnings of consolidated foreign subsidiaries as it is our intention that such earnings will remain invested in those companies.

We recognize income tax positions that are more likely than not to be realized and accrue interest related to unrecognized income tax positions, which is included as a component of the income tax provision, on the consolidated statements of operations.

## ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

## Foreign currency

We have foreign-based operations, primarily in Europe, South America, and Asia, which accounted for approximately 22 percent of our net sales in 2023. We have designated the local currency as the functional currency of our significant operations outside of the U.S. The primary currencies for which we have exchange rate exposure are the U.S. dollar versus the euro, the Japanese yen, the pound sterling, and the Chinese renminbi. In addition, certain of our domestic operations have sales to foreign customers. In the conduct of our foreign operations, we also make inter-company sales. All of this exposes us to the effect of changes in foreign currency exchange rates. Our earnings are therefore subject to change due to fluctuations in foreign currency exchange rates when the earnings in foreign currencies are translated into U.S. dollars. In some cases, to minimize the effects of such fluctuations, we use foreign exchange forward contracts to hedge firm and highly anticipated foreign currency cash flows. Our largest exposures are to the Chinese renminbi and the euro. A hypothetical 10 percent adverse change, excluding the impact of any hedging instruments, in the average Chinese renminbi and euro to U.S. dollar exchange rates during the year ended December 31, 2023, would have decreased our net sales and income before income taxes for the year ended December 31, 2023, by approximately $18 million or one percent and $6 million or two percent, respectively. Comparatively, a hypothetical 10 percent adverse change in the average Chinese renminbi and euro to U.S. dollar exchange rates during the year ended December 31, 2022 would have decreased our net sales and income before income taxes for the year ended December 31, 2022, by approximately $19 million or one percent and $7 million or two percent, respectively.

## Concentration of credit risk

The financial instruments that potentially subject Ingevity to concentrations of credit risk are accounts receivable. We limit our credit risk by performing ongoing credit evaluations and, when necessary, requiring letters of credit, guarantees, or collateral. Our largest customer as of December 31, 2023, had accounts receivable of $7.5 million and $9.3 million as of December 31, 2023 and 2022, respectively. Sales to our largest customer, which is from our Performance Materials segment, were approximately four percent of total net sales for each of the years ended December 31, 2023, 2022, and 2021, respectively. Sales to the automotive industry, which represents our largest industry concentration, were approximately 30 percent of our consolidated Net sales. No customers individually accounted for greater than 10 percent of Ingevity's consolidated Net sales.

## Commodity price risk

A portion of our manufacturing costs includes purchased raw materials, which are commodities whose prices fluctuate as market supply and demand fundamentals change. Accordingly, product margins and the level of our profitability tend to fluctuate with the changes in these commodity prices. The cost of energy is a manufacturing cost that is exposed to commodity pricing. Our sources of energy costs are diversified among electricity, steam and natural gas, with natural gas comprising our largest energy input.



## Crude tall oil price risk

Our results of operations are directly affected by the cost of our raw materials, particularly CTO, which represents approximately 26 percent of consolidated cost of sales and 51 percent of our full company raw materials purchases for the year ended December 31, 2023. Pricing for CTO is driven by the limited supply of the product and competing demands for its use, both of which drive pressure on its price. Our gross profit and margins could be adversely affected by increases in the cost of CTO if we are unable to pass the increases on to our customers. Based on average pricing during the year ended December 31, 2023, a hypothetical unhedged, unfavorable 10 percent increase in the market price for CTO would have increased our cost of sales for the year ended December 31, 2023, by approximately $31.6 million or three percent, which we may not have been able to pass on to our customers. Comparatively, based on average pricing during the year ended December 31, 2022, a hypothetical unhedged, unfavorable 10 percent increase in the market price for CTO would have increased our cost of sales for the year ended December 31, 2022 by approximately $13.4 million or one percent.

## Natural gas price risk

Natural gas, both direct and indirect, is our largest form of energy costs constituting approximately five percent of our cost of goods sold for the year ended December 31, 2023. Increases in natural gas costs, unless passed on to our customers, would adversely affect our results of operations. If natural gas prices increase significantly, our business or results of operations may be adversely affected. We enter into certain derivative financial instruments to mitigate expected fluctuations in market prices and the volatility to earnings and cash flow resulting from changes to the pricing of natural gas purchases. Refer to Note 9 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information on our natural gas price risk hedging program. For the year ended December 31, 2023, a hypothetical, unhedged 10 percent increase in natural gas pricing would have resulted in an increase to cost of sales of approximately $6.5 million or 53 basis points. As of December 31, 2023, we had 0.8 million and 0.2 million mmBTUS (millions of British Thermal Units) in the aggregate notional volume of outstanding natural gas commodity swap contracts and zero-cost collar option contracts, respectively, designated as cash flow hedges. Comparatively, for the year ended December 31, 2022, a hypothetical, unhedged 10 percent increase in natural gas pricing would have resulted in an increase to cost of sales of approximately $7.9 million or 70 basis points. As of December 31, 2023, open commodity contracts hedge forecasted transactions until December 2024. The fair value of the outstanding designated natural gas commodity hedge contracts as of December 31, 2023 and 2022 was a net liability of $0.9 million and $1.6 million, respectively.

## Interest Rate Risk

As of December 31, 2023, approximately $821 million of our borrowings include a variable interest rate component. As a result, we are subject to interest rate risk with respect to such floating-rate debt. For the year ended December 31, 2023, a hypothetical 100 basis point increase in the variable interest rate component of our borrowings would increase our annual interest expense by approximately $8 million or 10 percent. Comparatively, for the year ended December 31, 2022, a hypothetical 100 basis point increase in the variable interest rate component of our borrowings would have increased our annual interest expense by approximately $8 million or 11 percent.

During 2022, we had floating-to-fixed interest rate swaps with a combined notional amount of $166.2 million to manage the variability of cash flows in the interest rate payments associated with our existing LIBOR-based interest payments, effectively converting $166.2 million of our floating rate debt to a fixed rate. Per the terms of these instruments, we received floating rate interest payments based upon the three-month U.S. dollar LIBOR and in return were obligated to pay interest at a fixed rate of 3.79 percent until July 2023. Due to the repayment of our term loan (refer to Note 10 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information), in 2022, we terminated these interest rate swap instruments. Upon termination of the interest rate swap instruments, we reclassified a $1.7 million gain from AOCI into Interest income on the consolidated statement of operations. The fair value of outstanding interest rate instruments at December 31, 2023 and 2022 was an asset (liability) of zero.

Management's Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. The Company's internal control over financial reporting includes those policies and procedures that:

i. pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

ii. provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP and that receipts and expenditures of the Company are being made only in accordance with authorization of management and directors of the Company; and

iii. provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use or disposition of the Company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2023, based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013).

# Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Ingevity Corporation

## Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Ingevity Corporation and its subsidiaries (the "Company") as of December 31, 2023 and 2022, and the related consolidated statements of operations, of comprehensive income (loss), of stockholders' equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

## Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

## Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.



## Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

## Interim and Annual Goodwill Impairment Assessments – Performance Chemicals Reporting Unit

As described in Notes 2 and 8 to the consolidated financial statements, the Company’s consolidated goodwill balance was $527.5 million as of December 31, 2023, of which $349.4 million relates to the Performance Chemicals reporting unit. Management conducts an annual review of goodwill for potential impairment at October 1, or sooner if events or changes in circumstances indicate that the fair value of a reporting unit is below its carrying value. During the third quarter of 2023, management concluded that a triggering event occurred for the Performance Chemical’s reporting unit and, as a result management performed an analysis of the reporting unit’s goodwill as of September 1, 2023. The fair value of the reporting unit was determined using both the income approach and market approach. The income approach determines fair value based on a discounted cash flow model derived from a reporting unit’s long-term forecasted cash flows, and the market approach determines fair value based on the application of earnings multiples of comparable companies to projected earnings of the reporting unit. The amount of impairment loss is measured as the difference between the carrying value and the fair value of a reporting unit but is limited to the total amount of goodwill allocated to a reporting unit. The calculated estimated fair value of the reporting unit reflects a number of significant management assumptions and estimates including forecasted revenue growth rates, forecasted Earnings before Interest, Taxes, Depreciation and Amortization (“EBITDA”) margins, and discount rate. Management concluded that there was no impairment for the quarter ended September 30, 2023 or for the year ended December 31, 2023.

The principal considerations for our determination that performing procedures relating to the interim and annual goodwill impairment assessments of the Performance Chemicals reporting unit is a critical audit matter are (i) the significant judgment by management when determining the fair value estimates of the reporting unit, (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to forecasted revenue growth rates, forecasted EBITDA margins, and discount rate used in the income approach; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s interim and annual goodwill impairment assessments, including controls over the valuation of the Performance Chemicals reporting unit. These procedures also included, among others (i) testing management’s process for determining the fair value estimates of the reporting unit; (ii) evaluating the appropriateness of the discounted cash flow model; (iii) testing the completeness and accuracy of underlying data used in the discounted cash flow model; and (iv) evaluating the reasonableness of the significant assumptions used by management related to the forecasted revenue growth rates, forecasted EBITDA margins, and discount rate. Evaluating management’s significant assumptions related to the forecast of forecasted revenue growth rates and forecasted EBITDA margins involved evaluating whether the significant assumptions used by management were reasonable considering (i) the current and past performance of the Performance Chemicals reporting unit; (ii) the consistency with external market data; and (iii) whether these significant assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating (i) the appropriateness of the Company’s discounted cash flow model and (ii) the reasonableness of the discount rate.

## Note 1: Background

## Description of Business

Ingevity Corporation ("Ingevity," "the company," "we," "us," or "our") provides products and technologies that purify, protect, and enhance the world around us. Through a diverse team of talented and experienced people, we develop, manufacture, and bring to market solutions that are largely renewably sourced and help customers solve complex problems while making the world more sustainable. Our products are used in a variety of demanding applications, including adhesives, agrochemicals, asphalt paving, bioplastics, coatings, elastomers, lubricants, pavement markings, publication inks, oil exploration and production and automotive components. We operate in three reporting segments: Performance Materials, Performance Chemicals and Advanced Polymer Technologies.

During the first quarter of 2023, we realigned our segment reporting structure to increase transparency for our investors and better align with how our chief operating decision maker intends to measure segment operating performance and allocate resources across our operating segments. We separated our engineered polymers product line from the Performance Chemicals reportable segment into its own reportable segment, Advanced Polymer Technologies. This reportable segment change also resulted in our Performance Chemicals reporting unit for goodwill being split into two separate reporting units for the purposes of goodwill impairment testing.

Our Performance Materials segment manufactures products in the form of powder, granular, extruded pellets, extruded honeycombs, and activated carbon sheets. Performance Materials engineers, manufactures, and sells hardwood-based, chemically activated carbon products which are produced through a highly technical and specialized process primarily for use in gasoline vapor emission control systems in internal combustion engines and hybrid electric vehicles including cars, trucks, motorcycles, and boats. To maximize the productivity of our manufacturing assets, we also produce several other activated carbon products for food, water, beverage, and chemical purification applications.

Our Performance Chemicals segment consists of our road technologies (previously named pavement technologies) and industrial specialties product lines. Performance Chemicals products serve as critical inputs used in a variety of high-performance applications, including pavement construction, pavement preservation, pavement reconstruction and recycling, road markings (road technologies product line), as well as agrochemical dispersants, paper chemicals, and other diverse industrial uses (industrial specialties product line). On November 1, 2023 we announced a number of strategic actions designed to further reposition our Performance Chemicals reportable segment to improve the profitability and reduce the cyclicality of the Company as a whole. These actions increase our focus on growing our most profitable Performance Chemicals' product lines such as road technologies and accelerate our transition to non-crude tall oil ("CTO") based fatty acids. This initiative will result in the reduction, and in some cases exit, of certain historical end-use markets of our industrial specialties product line such as adhesives, publication inks, and oilfield, representing approximately $300.0 million of net sales. The announced actions include the permanent closure of our Performance Chemicals' CTO refinery and the closure of our manufacturing plant located in DeRidder, Louisiana (the "DeRidder Plant"), including the polyol production assets associated with the Advance Polymer Technologies reportable segment, as well as additional corporate and business cost reduction actions.

Our Advanced Polymer Technologies segment produces caprolactone and caprolactone-based specialty polymers for use in coatings, resins, elastomers, adhesives, bioplastics, and medical devices.

## Basis of Consolidation and Presentation

The accompanying Consolidated Financial Statements of Ingevity were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The significant accounting policies described in Note 2, together with the other notes that follow, are an integral part of the Consolidated Financial Statements. The Consolidated Financial Statements include the accounts of Ingevity and subsidiaries in which a controlling interest is maintained.

## Note 2: Summary of Significant Accounting Policies

Estimates and assumptions: We are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Our estimates are based on historical experiences, facts, and circumstances available at the time and various other assumptions that we believe are reasonable. Actual results may differ from those estimates.



# Ingevity Corporation
Notes to the Consolidated Financial Statements
December 31, 2023

Cash equivalents: Highly liquid securities with an original maturity of three months or less are considered cash equivalents.

Accounts receivable, net of allowance: Accounts receivable, net on the consolidated balance sheets are comprised of trade receivables less allowances for doubtful accounts and credit losses (herein referred to as "credit losses"). Trade receivables consist of amounts owed to Ingevity from customer sales and are recorded at the invoiced amounts when revenue is recognized and generally do not bear interest. The allowance for credit losses is our best estimate of the amount of probable loss in the existing accounts receivable. We determine the allowance based on our expected future credit losses, which is partly based on historical write-off experience, current collection trends, and external business factors such as economic factors, including regional bankruptcy rates and political factors. Past-due balances over a specified amount are reviewed individually for collectability. Account balances are charged off against the allowance when it is probable that the receivable will not be recovered. Allowance for credit losses at December 31, 2023 and 2022, was $1.1 million and $0.5 million, respectively.

Concentration of credit risk: The financial instruments that potentially subject Ingevity to concentrations of credit risk are accounts receivable. We limit our credit risk by performing ongoing credit evaluations and, when necessary, requiring letters of credit, guarantees, or collateral. Our largest customer as of December 31, 2023 had accounts receivable of $7.5 million and $9.3 million as of December 31, 2023 and 2022, respectively. Sales to our largest customer were approximately four percent of total net sales for each of the years ended December 31, 2023, 2022, and 2021, respectively. Sales to the automotive industry, which represents our largest industry concentration, were approximately 30 percent of our consolidated Net sales. No customers individually accounted for greater than 10 percent of Ingevity's consolidated Net sales.

Inventories, net: Inventories are valued at lower of cost or net realizable value, except for inventories determined using the last-in, first-out method (“LIFO”), which are valued at the lower of LIFO or market cost. The value of our U.S. inventories is determined using LIFO for the majority of our raw materials, finished goods, and production materials. The value of all other inventories, including stores and supplies inventories and inventories of non-U.S. operations, is determined by the first-in, first-out ("FIFO") or average costs methods. Elements of cost in inventories include raw materials, direct labor, and manufacturing overhead. We routinely assess inventory for both potential obsolescence and potential declines in anticipated selling prices to derive a market value for the inventory on hand. This review also includes an analysis of potentially obsolete, unmarketable, slow-moving, or overvalued inventory. If necessary, we will impair any inventories by an amount equal to the difference between the value of the held inventory (i.e., cost) and its estimated net realizable value for FIFO and average cost inventories and market value for LIFO inventories.

Property, plant, and equipment: Owned assets are recorded at cost. Also included in the cost of these assets is interest on funds borrowed during the construction period. When assets are sold, retired or disposed of, their cost and related accumulated depreciation are removed from the consolidated balance sheet, and any resulting gain or loss is reflected within the consolidated statement of operations. Repair and maintenance costs that materially add to the value of the asset or prolong its useful life are capitalized and depreciated based on the extension of the useful life.

Repair and maintenance costs: We expense routine repair and maintenance costs as we incur them. We defer expenses incurred during planned major maintenance activities and record these amounts to Prepaid and other current assets on our consolidated balance sheet. Deferred amounts are recognized as expense ratably over the shorter of the estimated interval until the next major maintenance activity or the life of the deferred item. The cash outflows related to these costs are included in operating activities within the consolidated statement of cash flows. The timing of this maintenance can vary by manufacturing plant and has a significant impact on our results of operations in the period performed primarily due to lost production during the maintenance period.

Depreciation: The cost of property, plant, and equipment is depreciated, utilizing the straight-line method, over the estimated useful lives of the assets, the majority of which range from 20 to 40 years for buildings and leasehold improvements and 5 to 30 years for machinery and equipment. The following table provides details on the useful lives and proportion of our machinery and equipment (“M&E”) in each useful life category.

Leases: We lease various assets for use in our operations that are classified as both operating and financing leases. At contract inception, we determine that a lease exists if the contract conveys the right to control an identified asset for a period of time in exchange for consideration. Control is considered to exist when the lessee has the right to obtain substantially all of the economic benefits from the use of an identified asset as well as the right to direct the use of that asset. If a contract is considered to be a lease, we recognize a lease liability based on the present value of the future lease payments, with an offsetting entry to recognize a right-of-use asset. As a majority of our leases do not provide an explicit rate within the lease, an incremental borrowing rate is used, which is based on information available at the commencement date. The determination of the incremental borrowing rate for each individual lease was impacted by the following assumptions: lease term, currency, and the economic environment for the physical location of the leased asset.

Our operating leases principally relate to the following leased asset classes:

<table><tr><td>Leased Asset Class</td><td>Remaining Lease Term</td></tr><tr><td>Administrative offices</td><td>1 to 15 years</td></tr><tr><td>Manufacturing buildings</td><td>4 to 50 years</td></tr><tr><td>Manufacturing and office equipment</td><td>0 to 11 years</td></tr><tr><td>Warehousing and storage facilities</td><td>3 to 10 years</td></tr><tr><td>Vehicles</td><td>3 to 5 years</td></tr><tr><td>Rail cars</td><td>0 to 10 years</td></tr></table>

Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet. Lease expense is recognized on a straight-line basis over the expected lease term. Some of our leases include options to extend the lease term at our sole discretion. We account for lease and non-lease components together as a single component for all lease asset classes. The depreciable life of assets and leasehold improvements is limited by the expected lease term unless there is a transfer of title or purchase option reasonably certain of exercise. Certain leases provide for escalation of the lease payments, as well as maintenance costs and taxes increase.

Asset retirement obligations: We record asset retirement obligations (“AROs”) at fair value at the time the liability is incurred if we can reasonably estimate the settlement date. The associated AROs are capitalized as part of the carrying amount of related long-lived assets. In future periods, the liability is accreted to its present value and the capitalized cost is depreciated over the useful life of the related asset. We also adjust the liability for changes resulting from the passage of time and/or revisions to the timing or the amount of the original estimate. Upon the retirement of the long-lived asset, we either settle the obligation for its recorded amount or incur a gain or loss. The carrying amounts for the AROs for the years ended December 31, 2023 and 2022 are $12.9 million and $4.3 million, respectively, and are included in Accrued expenses and Other liabilities on the consolidated balance sheet.

Impairment of long-lived assets: We periodically evaluate whether current events or circumstances indicate that the carrying value of our long-lived assets, including intangible assets, to be held and used may not be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the long-lived asset, or the appropriate grouping of assets, is compared to carrying value to determine whether impairment exists.

If an asset is determined to be impaired, the loss is measured based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques,



# Ingevity Corporation
Notes to the Consolidated Financial Statements
December 31, 2023

including a discounted value of estimated future cash flows. We report an asset to be disposed of at the lower of its carrying value or its estimated net realizable value.

Goodwill and other intangible assets: Goodwill represents the excess of cost of an acquired business over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed in a business combination. We conduct a required annual review of goodwill for potential impairment at October 1, or sooner if events or changes in circumstances indicate that the fair value of a reporting unit is below its carrying value. Our reporting units are our operating segments, i.e., Performance Materials, Performance Chemicals, and Advanced Polymer Technologies. If the carrying value of a reporting unit that includes goodwill exceeds its fair value, which is determined using both the income approach and market approach, goodwill is considered impaired. The income approach determines fair value based on discounted cash flow model derived from a reporting unit's long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to projected earnings of the reporting unit. The amount of impairment loss is measured as the difference between the carrying value and the fair value of a reporting unit but is limited to the total amount of goodwill allocated to the reporting unit. In performing the fair value analysis, management makes various judgments, estimates and assumptions, the most significant of which are the assumptions related to revenue growth rates, Earnings before Interest, Taxes, Depreciation and Amortization ("EBITDA") margin, and discount rate.

The factors we considered in developing our estimates and projections for cash flows include, but are not limited to, the following: (i) macroeconomic conditions; (ii) industry and market considerations; (iii) costs, such as increases in raw materials, labor, or other costs; (iv) our overall financial performance; and (v) other relevant entity-specific events that impact our reporting units.

The determination of whether goodwill is impaired involves a significant level of judgment in the assumptions underlying the approach used to determine the estimated fair values of our reporting units. We believe that the estimates and assumptions used in our impairment assessment are reasonable; however, these assumptions are judgmental and variations in any assumptions could result in materially different calculations of fair value. We will continue to evaluate goodwill on an annual basis as of October 1, and whenever events or changes in circumstances, such as significant adverse changes in operating results, market conditions, or changes in management's business strategy indicate that there may be a probable indicator of impairment. It is possible that the assumptions used by management related to the evaluation may change or that actual results may vary significantly from management's estimates.

Our fiscal year 2023 annual goodwill impairment test was performed as of October 1, 2023. We determined that the fair value of our reporting units were in excess of their carrying value and therefore concluded that no goodwill impairment existed. There were no events or circumstances indicating that goodwill might be impaired as of December 31, 2023. No impairment charges have been recognized historically.

Other intangible assets are comprised of finite-lived intangible assets consisting primarily of brands (representing trademarks, trade names and know-how), customer contracts and relationships, and developed technology. Other intangible assets are amortized over their estimated useful lives which range from 3 to 20 years. Any potential impairment for definite-lived intangible assets will be calculated in the same manner as disclosed under impairment of property, plant and equipment. Customer relationships are amortized in a manner that reflects the pattern in which the economic benefits of the intangible asset are consumed.

Capitalized software: Capitalized software for internal use is included within Other assets on the consolidated balance sheets. Amounts capitalized are presented in Capital expenditures on our consolidated statements of cash flow. Capitalized software is amortized using the straight-line over the estimated useful lives ranging from 3 to 15 years. Amortization is recorded to Costs of sales on our consolidated statements of operations for software directly used in the production of inventory and Selling, general, and administrative expenses on our consolidated statements of operations for software used for non-production related activities.

Strategic investments: We have a variety of strategic investments that are classified as long-term assets on the consolidated balance sheets. Our strategic investments are accounted for under either the equity method of accounting or the measurement alternative, where fair value is not readily determinable. We use the equity method of accounting for investments that we do not control, but for which we have the ability to exercise significant influence.

For strategic investments that are accounted for under the equity method of accounting, our initial investment is recorded at cost. Subsequently, the carrying value for these investments will be impacted by our proportionate share of



# Ingevity Corporation
Notes to the Consolidated Financial Statements
December 31, 2023

undistributed earnings or loss, distributions, amortization or accretion of basis differences, and other-than-temporary impairments. Subsequent adjustments to our initial investment are recorded within Other (income) expense, net on the consolidated statement of operations.

Strategic investments accounted for under the measurement alternative, where fair value is not readily determinable, are accounted for at cost. Adjustments for observable changes in prices or impairments are recognized in Other (income) expense, net in our consolidated statements of operations.

At each reporting period, we evaluate each investment to determine whether events or changes in business circumstances indicate that the carrying value of the investment may not be fully recoverable.

Legal liabilities: We recognize a liability for legal contingencies when a loss is probable and reasonably estimable. Third-party fees for legal services are expensed as incurred. If only a range of estimated losses can be determined, we accrue an amount that reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, we accrue the low end of the range. If an unfavorable outcome is reasonably possible but not probable, we will disclose an estimate of the reasonably possible loss or range of loss. If we cannot estimate the loss or range of losses arising from a legal proceeding, we will disclose that an estimate cannot be made. In assessing the materiality of a legal proceeding, we evaluate, among other factors, the amount of monetary damages claimed, as well as the potential impact of non-monetary remedies sought by plaintiffs that may require us to change our business practices in a manner that could have a material adverse impact on our business.

Revenue recognition: Our revenue is derived from contracts with customers, and substantially all our revenue is recognized when products are either shipped from our manufacturing and warehousing facilities or delivered to the customer. Revenue, net of returns and customer incentives, is based on the sale of manufactured products. Revenues are recognized when performance obligations under the terms of a contract with our customer are satisfied; generally, this occurs with the transfer of control of our products. For certain limited contracts, where we are producing goods with no alternative use and for which we have an enforceable right to payment for performance completed to date, we are recognizing revenue as goods are manufactured, rather than when they are shipped. Revenues are presented as Net sales on the consolidated statements of operations.

Since Net sales are derived from product sales only, we have disaggregated our Net sales by our product lines within each reportable segment. Net sales are measured as the amount of consideration we expect to receive in exchange for transferring goods. Sales, value add, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Sales returns and allowances are not a normal practice in the industry and are not significant. Certain customers may receive cash-based incentives, including discounts and volume rebates, which are accounted for as variable consideration and included within Net sales. Shipping and handling fees billed to customers are included within Net sales. If we pay for the freight and shipping, we recognize the cost when control of the product has transferred to the customer as an expense within Cost of sales on the consolidated statements of operations. Payment terms with our customers are typically in the range of zero to sixty days. Because the period between when we transfer a promised good to a customer and when the customer pays for that good will be one year or less, we elect not to adjust the promised amount of consideration for the effects of any financing component, as it is not significant.

Cost of sales: Costs primarily consist of the cost of inventory sold and other production related costs. These costs include raw materials, direct labor, manufacturing overhead, packaging costs, and maintenance costs. Shipping and handling costs are recorded within Cost of sales on the consolidated statements of operations.

Royalty expense: We have licensing agreements with third parties requiring us to pay royalties for certain technologies we use in the manufacturing of our products. Royalty expense is recognized as incurred and recorded within Cost of sales on the consolidated statements of operations.

Selling, general, and administrative expenses: Costs are expensed as incurred and primarily include employee compensation costs related to sales and office personnel, office expenses, and other expenses not directly related to our manufacturing operations. Costs also include advertising and promotional costs.

Research and technical expenses: Costs are expensed as incurred and primarily include employee compensation, technical equipment costs, material testing, and innovation-related expenses.

Notes to the Consolidated Financial Statements
December 31, 2023

Restructuring and other (income) charges, net: We regularly perform strategic reviews and assess the return on our operations, which sometimes results in a plan to restructure the business. The cost and benefit of these strategic restructuring initiatives are recorded within Restructuring and other (income) charges, net on the consolidated statement of operations. These costs are excluded from our operating segment results.

We record an accrual for severance and other costs under the provisions of the relevant accounting guidance. Additionally, in some restructuring plans, write-downs of long-lived assets may occur. Two types of assets are impacted: assets to be disposed of by sale and assets to be abandoned. Assets to be disposed of by sale are measured at the lower of carrying amount or estimated net proceeds from the sale. Assets to be abandoned with no remaining future service potential are written down to amounts expected to be recovered. The useful lives of assets to be abandoned that have a remaining future service potential are adjusted and depreciation is recorded over the adjusted useful life.

Non-operating income and expense: Non-operating income and expenses are included within Other (income) expense, net on the consolidated statement of operations. Included within Other (income) expense, net, among other items, are gains and losses associated with crude tall oil ("CTO") resales. As further described in Note 1 and Note 15, due to the DeRidder Plant closure and the corresponding reduced CTO refining capacity, we may be obligated, under an existing CTO supply contract, to purchase CTO volumes through 2025 at amounts in excess of required CTO volumes. We intend to manage our CTO volumes by reselling excess volumes (herein referred to as "CTO resales") in the open market.

Our Performance Chemicals reportable segment is in the business of producing, primarily from CTO-based feedstocks, derivative specialty chemicals for sale to third-party customers. As a result of the Performance Chemicals' repositioning, we are selling excess CTO volumes, which is outside of the ordinary course of business, that is, not a normal ongoing part of our operations and not core to our business. The excess CTO volumes, calculated as the volume directly attributable to reduced CTO refining capacity as defined under the contractual terms of the CTO supply contract, on hand at period end will be valued at the lower of cost or expected selling price, less costs to sell. Volumes on hand at period end and any pending CTO resale receivables will be recorded to Other current assets on the consolidated balance sheet. Any liabilities associated with the purchases of the excess CTO volumes will be recorded to Accrued expenses on the consolidated balance sheet. We will recognize the net gains or losses associated with the CTO resale activities within Other (income) expenses, net on the consolidated statement of operations.

Income taxes: We are subject to income taxes in the U.S. and numerous foreign jurisdictions, including China and the United Kingdom ("UK"). The provision for income taxes includes income taxes paid, currently payable or receivable, and deferred taxes. We follow the asset and liability method of accounting for income taxes in accordance with current accounting standards regarding the accounting for income taxes. Under this method, deferred income taxes are recognized based on the temporary differences between the financial reporting and tax bases of assets and liabilities, and are measured using the enacted tax rates and laws in effect at the time the underlying assets or liabilities are recovered or settled. The ability to realize deferred tax assets is evaluated through the forecasting of taxable income, historical and projected future operating results, the reversal of existing temporary differences, and the availability of tax planning strategies. Valuation allowances are recognized to reduce deferred tax assets when it is more-likely-than-not that a tax benefit will not be realized. We do not provide income taxes on undistributed earnings of consolidated foreign subsidiaries, as it is our intention that such earnings will remain invested in those companies.

We recognize income tax positions that are more-likely-than-not to be realized and accrue interest related to unrecognized income tax positions, which is included as a component of the income tax provision, on the consolidated statements of operations.

Earnings per Share: Basic earnings (loss) per share is computed by dividing net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share reflects the dilution that could occur if the outstanding stock-based compensation awards, including any unvested awards, were vested and exercised, resulting in the issuance of common stock as determined under the treasury stock method. Diluted earnings (loss) per share is computed by dividing net income (loss) for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding for the period. The calculation of diluted net income per share excludes all antidilutive common shares. In periods where we incur a net loss, stock-based compensation awards are excluded from the calculation of earnings per share as their inclusion would have an anti-dilutive effect.

Pension and postretirement benefits: We provide both qualified and non-qualified pension and postretirement benefit plans to our employees. The expense related to the current employees, as well as the expense related to retirees, are included within the Consolidated Financial Statements. The costs (or benefits) and obligations related to these benefits reflect key assumptions related to general economic conditions, including interest (discount) rates, healthcare cost trend rates, and expected return on plan assets. The costs (or benefits) and obligations for these benefit programs are also affected by other assumptions, such as average retirement age, mortality rates, employee turnover, and plan participation. To the extent our plans' actual experience, as influenced by changing economic and financial market conditions or by changes to our own plans' demographics, differs from these assumptions, the costs and obligations for providing these benefits, as well as the plans' funding requirements, could increase or decrease. When actual results differ from our assumptions, the difference is typically recognized over future periods. In addition, the unrealized gains and losses related to our pension and postretirement benefit obligations may also affect periodic benefit costs (or benefits) in future periods.

Share-based compensation: We recognize compensation expense within our Consolidated Financial Statements for all share-based compensation arrangements. Share-based compensation cost is measured at the date of grant, based on the fair value of the award, and expense is recognized over the grantee's requisite service period; forfeitures are recognized as they occur. We calculate the fair value of our stock options using the Black-Scholes option pricing model. The fair value of restricted stock units ("RSUs"), non-employee director deferred stock units ("DSUs"), and performance-based restricted stock units ("PSUs") is determined using our closing stock price on the date of the grant. Beginning in 2023, certain granted PSUs include a market condition, relative total shareholder return ("rTSR"), which requires that the fair value of the award be calculated using a Monte Carlo simulation. Substantially all compensation expense related to share-based awards is recorded as a component of Selling, general and administrative expenses within the consolidated statements of operations.

Operating segments: Our operating segments are Performance Materials, Performance Chemicals, and Advanced Polymer Technologies. Our operating segments were determined based upon the nature of the products produced, the nature of the production process, the type of customer for the products, the similarity of economic characteristics, and the manner in which management reviews results. Our chief operating decision maker evaluates the business at the segment level when making decisions about allocating resources and assessing the performance of Ingevity as a whole.

Fair value measurements: We have categorized our assets and liabilities that are recorded at fair value, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the assets and liabilities fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair value measurement of the instrument. The carrying value of our financial instruments: cash and cash equivalents, other receivables, other payables, and accrued liabilities, approximate their fair values due to the short-term nature of these financial instruments.

Derivative financial instruments: We are exposed to market risks, such as the impact of changes in interest rates on our floating rate debt, foreign currency exchange rates due to transactions denominated in a variety of foreign currencies, and commodity prices due to purchases of certain raw materials and inputs. Changes in these rates and prices may have an impact on our future cash flow and earnings. We formally document all relationships between the derivative financial instrument and the hedged item, as well as the risk management objective and strategy for undertaking various hedge transactions. We do not hold or issue derivative financial instruments for speculative or trading purposes. We enter into derivative financial instruments which are governed by policies, procedures, and internal processes set forth by our Board of Directors.

Our risk management program also addresses counterparty credit risk by selecting only major financial institutions with investment grade ratings. Once the derivative financial instrument is entered into, we continuously monitor the financial institutions' credit ratings and our credit risk exposure held by the financial institution. When appropriate, we reallocate exposures across multiple financial institutions to limit credit risk. If a counterparty fails to fulfill its performance obligations under the derivative financial instrument, then Ingevity is exposed to credit risk equal to the fair value of the financial instrument. Derivative assets and liabilities are recorded on our consolidated balance sheets at fair value and are presented on a gross basis. Due to our proactive mitigation of these potential credit risks, we anticipate performance by our counterparties to these contracts, and therefore, no material loss is expected. In order to mitigate the impact of market risks, we have and may enter into both net investment hedges and cash flow hedges.

Cash flow hedges: Cash flow hedges are derivative financial instruments designated as and used to hedge the exposure to variability in expected future cash flows that are attributable to a particular risk. The derivative financial instruments that are



# Ingevity Corporation
Notes to the Consolidated Financial Statements
December 31, 2023

designated and qualify as a cash flow hedge are recorded on the consolidated balance sheet at fair value, and the changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the anticipated cash flows of the underlying exposures being hedged. The gains and losses arising from qualifying hedging instruments are reported as a component of Accumulated other comprehensive income (loss) ("AOCI") located within the consolidated balance sheets and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The reclassification gain or losses of the hedge from AOCI are recorded in the same financial statement caption on the consolidated statements of operations as the hedged item. For example, designated cash flow hedges entered to minimize foreign currency exchange risk of forecasted revenue transactions are recorded to Net sales on the consolidated statements of operations when the forecasted transaction occurs. Designated commodity cash flow hedges gains or losses recorded in AOCI are recognized within Cost of sales on the consolidated statements of operations when the inventory is sold.

Net investment hedges: Net investment hedges are defined as derivative or non-derivative instruments, which are designated as and used to hedge the foreign currency exposure of the net investment in certain foreign operations. The net of the change in the hedge instrument and the item being hedged against for qualifying net investment hedges is reported as a component of the foreign currency adjustments ("CTA") within AOCI on the consolidated balance sheet. The gains (losses) on net investment hedges are reclassified to earnings only when the related CTA are required to be reclassified, usually upon the sale or liquidation of the investment.

Treasury stock: We record shares of common stock repurchased at cost as treasury stock, resulting in a reduction of stockholders' equity on the consolidated balance sheets. When the treasury shares are contributed under our employee benefit plans or issued for option exercises, we use a first-in, first-out ("FIFO") method for determining cost. The difference between the cost of the shares and the market price at the time of contribution to an employee benefit plan is added to or deducted from Additional paid-in capital on the consolidated balance sheets.

Translation of foreign currencies: The local currency is the functional currency for all of our significant operations outside the U.S., consisting primarily of the euro, the Japanese yen, the pound sterling, and the Chinese renminbi. The assets and liabilities of our foreign subsidiaries are translated into U.S. dollars using period-end exchange rates, and adjustments resulting from these financial statement translations are reported as a component of CTA within AOCI on the consolidated balance sheets. Revenues and expenses are translated at average rates prevailing during each period.

Business combinations: Accounting for business combinations which requires, among other things, the acquiring entity in a business combination to recognize the fair value of the assets acquired and liabilities assumed; the recognition of acquisition-related costs within the consolidated results of operations; the recognition of restructuring costs within the consolidated results of operations for which the acquirer becomes obligated after the acquisition date; and contingent purchase consideration to be recognized at fair value on the acquisition date with subsequent adjustments recognized on the consolidated statement of operations. We generally use qualified third-party consultants to assist management in determining the fair value of assets acquired and liabilities assumed. This includes, when necessary, assistance with the determination of lives and valuation of tangible property, plant, and equipment and identifiable intangibles, assisting management in determining the fair value of obligations associated with employee-related liabilities, and assisting management in assessing obligations associated with legal and environmental claims. The purchase price allocation process allows us to refine these estimates over a measurement period not to exceed one year to reflect new information obtained surrounding facts and circumstances existing at the acquisition date.

The fair value assigned to identifiable intangible assets acquired is determined primarily by using an income approach, which is based on assumptions and estimates made by management. Significant assumptions utilized in the income approach are the attrition rate, revenue growth rates, EBITDA margins, royalty rates, and the discount rate. These assumptions are based on company-specific information and projections, which are not observable in the market and are therefore considered Level 2 and Level 3 measurements. The excess of the purchase price over the fair value of the identified assets and liabilities is recorded as goodwill. Based on the acquired business' end markets and products, as well as how the chief operating decision maker will review the business results, determines the most appropriate operating segment for which to integrate the acquired business. Goodwill acquired, if any, is allocated to the reporting unit within or at the operating segment for which the acquired business will be integrated. Selection of the appropriate reporting unit is based on the level at which discrete financial information is available and reviewed by business management post-integration. Operating results of the acquired entity are reflected within the Consolidated Financial Statements from the date of acquisition.

Reclassifications: Certain prior year amounts have been reclassified to conform with the current year's presentation.

## Note 3: New Accounting Guidance

The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC" or "Codification") is the sole source of authoritative GAAP other than the U.S. Securities and Exchange Commission ("SEC") issued rules and regulations that apply only to SEC registrants. The FASB issues an Accounting Standards Update ("ASU") to communicate changes to the Codification. We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are not expected to have a material impact on the Consolidated Financial Statements.

## Recently Issued Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting: Improvements to Reportable Segment Disclosures”, which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The purpose of the amendment is to provide readers of the financial statements with information to better understand an entity’s overall performance and assess potential future cash flows. The guidance is effective beginning with our 2024 fiscal year consolidated financial statements and will be applied to all prior periods presented in the financial statements. We are currently evaluating the potential impact of adopting this new guidance on our Consolidated Financial Statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures”, which is intended to enhance income tax disclosures around the rate reconciliation and income taxes paid. The purpose of the amendment is to provide readers of the financial statements with information to better assess the differences between the effective tax rate and the statutory tax rate across multiple jurisdictions, enabling them to understand tax implications around operational opportunities and potential future cash flows. The guidance is effective beginning with our 2025 fiscal year consolidated financial statements. Early adoption is permitted and we are currently evaluating the potential impact of adopting this new guidance on our Consolidated Financial Statements and related disclosures.

Both the asset and liability related to investment securities are recorded at fair value and are included within "Other assets" and "Other liabilities" on the consolidated balance sheets, respectively. In addition to the investment securities, we also had company-owned life insurance related to the deferred compensation arrangement recorded at cash surrender value in "Other assets" of $14.9 million and $13.3 million at December 31, 2023 and 2022, respectively.

## Nonrecurring Fair Value Measurements

There were no nonrecurring fair value measurements on the consolidated balance sheet during the years ended December 31, 2023 and 2022.

## Strategic Investments

## Equity Method Investments

The aggregate carrying value of all strategic equity method investments was $16.0 million and $28.2 million at December 31, 2023 and 2022, respectively. During the first quarter of 2023, we sold a strategic equity method investment for $31.5 million, resulting in a $19.3 million gain, recorded within "Other (income) expense, net" on the consolidated statement of operations. There were no adjustments to the carrying value of equity method investments for impairment for the periods ended, December 31, 2023 and 2022.

During 2022, we entered into an investment with a venture capital fund for $0.8 million, which is accounted for under the equity method of accounting. As of December 31, 2023 and 2022, respectively, we had approximately $5.6 million and $6.7 million of unfunded commitments, which we anticipate will be paid over a period of 10 years. The carrying value of our strategic equity investment was $1.7 million and $0.7 million at December 31, 2023 and 2022, respectively.

## Measurement Alternative Investments

The aggregate carrying value of all measurement alternative investments where fair value is not readily determinable totaled $83.2 million and $80.8 million at December 31, 2023 and 2022, respectively. There were no adjustments to the carrying value of the measurement alternative method investments for impairment or observable price changes for the periods ended December 31, 2023 or 2022.

## Restricted Investment

Our restricted investment is a trust managed in order to secure repayment of the finance lease obligation associated with Performance Materials' Wickliffe, Kentucky, manufacturing site at maturity. The trust, presented as Restricted investment on our consolidated balance sheets, originally purchased long-term bonds that mature through 2026. The principal received at maturity of the bonds, along with interest income that is reinvested in the trust, are expected to be equal to or more than the $80.0 million finance lease obligation that is due in 2027. Because the provisions of the trust provide us the ability, and it is our intent, to hold the investments to maturity, the investments held by the trust are accounted for as held to maturity ("HTM"); therefore, they are held at their amortized cost. The investments held by the trust earn interest at the stated coupon rate of the invested bonds. Interest earned on the investments held by the trust is recognized and presented as interest income on our consolidated statement of operations. As interest from the bonds is received and as bonds mature, any proceeds not reinvested are held in highly liquid securities and treated as restricted cash.

At December 31, 2023 and 2022, the carrying value of our restricted investment, which is accounted for as HTM and therefore held at amortized costs, was $79.1 million and $78.0 million, net of an allowance for credit losses of $0.2 million and $0.6 million and included restricted cash of $15.4 million and $7.0 million, respectively. The fair value at December 31, 2023 and 2022 was $76.7 million and $74.7 million, respectively, based on Level 1 inputs.

The following table shows the total amortized cost of our HTM debt securities by credit rating, excluding the allowance for credit losses and cash. The primary factor in our expected credit loss calculation is the composite bond rating. As the rating decreases, the risk present in holding the bond is inherently increased, leading to an increase in expected credit losses.

<table><tr><td rowspan="2">In millions</td><td colspan="6">HTM Debt Securities</td></tr><tr><td>AA+</td><td>AA-</td><td>A</td><td>A-</td><td>BBB+</td><td>Total</td></tr><tr><td>December 31, 2023</td><td>$ 13.3</td><td>10.4</td><td>13.2</td><td>17.0</td><td>10.0</td><td>$ 63.9</td></tr><tr><td>December 31, 2022</td><td>$ 13.4</td><td>10.5</td><td>13.2</td><td>14.1</td><td>20.4</td><td>$ 71.6</td></tr></table>

## Debt and Finance Lease Obligations

At December 31, 2023 and 2022, the carrying value of finance lease obligations was $101.1 million and $101.9 million, respectively, and the fair value was $105.7 million and $106.2 million, respectively. The fair value of our finance lease obligations is based on the period-end quoted market prices for the obligations, using Level 2 inputs. The fair value of all other finance lease obligations approximates their carrying values.

The carrying value, excluding debt issuance fees, of our variable rate debt was $821.4 million and $828.0 million as of December 31, 2023 and 2022, respectively. The carrying value of our variable rate debt is a reasonable estimate of the fair value.

At December 31, 2023 and 2022, the carrying value of our fixed rate debt was $550.0 million and $550.0 million, respectively, and the fair value was $494.6 million and $471.8 million, respectively, based on Level 2 inputs.

(1) The increase in the LIFO balance in 2023 is primarily attributable to the significant inflation in the price of crude tall oil ("CTO") which is the primary raw material for our Performance Chemicals reportable segment.

As of December 31, 2023, approximately 27 percent, 8 percent, and 65 percent of our Inventories, net, were accounted for under the FIFO, average cost, and LIFO methods, respectively. As of December 31, 2022, approximately 47 percent, 8 percent, and 45 percent of our Inventories, net, were accounted for under the FIFO, average cost, and LIFO methods, respectively.

## Note 7: Property, Plant, and Equipment, net

Property, plant, and equipment, net consist of the following:

<table><tr><td rowspan="2">In millions</td><td colspan="2">December 31,</td></tr><tr><td>2023</td><td>2022</td></tr><tr><td>Machinery and equipment</td><td>$ 1,244.6</td><td>$ 1,162.7</td></tr><tr><td>Buildings and leasehold improvements</td><td>217.4</td><td>200.9</td></tr><tr><td>Land and land improvements</td><td>26.3</td><td>24.9</td></tr><tr><td>Construction in progress</td><td>92.8</td><td>120.9</td></tr><tr><td>Total cost</td><td>$ 1,581.1</td><td>$ 1,509.4</td></tr><tr><td>Less: accumulated depreciation \( ^{(1)} \)</td><td>(818.9)</td><td>(710.8)</td></tr><tr><td>Property, plant, and equipment, net \( ^{(2)} \)</td><td>$ 762.2</td><td>$ 798.6</td></tr></table>

(1) As a result of the Performance Chemicals repositioning, as further described in Note 15, we accelerated the depreciation of certain property, plant and equipment assets in 2023. This resulted in $46.3 million of additional expense in 2023, which is included in Restructuring and other (income) charges, net within the consolidated statement of operations.

(2) This includes finance leases related to machinery and equipment of $94.2 million and $94.3 million, and net carrying value of $22.7 million and $25.2 million; buildings and leasehold improvements of $39.2 million and $39.6 million, and net carrying value of $32.3 million and $34.9 million, respectively. Amortization expense associated with these finance leases is included within depreciation expense. The payments remaining under these finance lease obligations are included within Note 13.

Depreciation expense was $81.5 million, $70.9 million, and $70.6 million for the years ended December 31, 2023, 2022, and 2021, respectively.

## Note 8: Goodwill and Other Intangible Assets, net

## Goodwill

As described in Note 1, we reorganized our segment reporting structure to increase transparency for our investors and better align with the markets and customers we serve through each of our segments. This structure is also consistent with the manner in which information is presently used internally by our chief operating decision maker to evaluate performance and make resource allocation decisions. This reportable segment change impacted the identification of our Performance Chemicals reporting unit, resulting in two reporting units, Performance Chemicals and Advanced Polymer Technologies.

We have reallocated goodwill as of January 1, 2023, to align to our new reporting unit structure by using a relative fair value approach and tested goodwill for impairment immediately before and after the realignment; no impairment was identified.

During the third quarter of 2023, continued reduction in demand in industrial end markets has negatively impacted our ability to offset elevated CTO costs through pricing actions within our Performance Chemicals' reportable segment, particularly in our industrial specialties product line. CTO is essential to our industrial specialties and some of our road technologies product lines within our Performance Chemicals reportable segment. As a result, we concluded that a triggering event occurred for our Performance Chemicals' reporting unit, and we performed an analysis of the reporting unit's goodwill, intangibles and long-lived assets as of September 1, 2023. Our analysis included significant assumptions such as: revenue growth rate, Earnings before Interest, Taxes, Depreciation and Amortization ("EBITDA") margin, and discount rate, which are judgmental and variations in any assumptions could result in materially different calculations of fair value. We concluded that there was no impairment for the quarter ended September 30, 2023.

Our fiscal year 2023 annual goodwill impairment test was performed as of October 1, 2023. We determined that the fair value of our reporting units were in excess of their carrying value and therefore concluded that no goodwill impairment existed. There were no events or circumstances indicating that goodwill might be impaired as of December 31, 2023.

Based on the current carrying values of intangible assets, estimated pre-tax amortization expense for the next five years is as follows: 2024 - $53.8 million, 2025 - $29.5 million, 2026 - $28.8 million, 2027 - $28.8 million and 2028 - $28.8 million. The estimated pre-tax amortization expense may fluctuate due to changes in foreign currency exchange rates.

## Note 9: Financial Instruments and Risk Management

## Net Investment Hedges

During 2022, we terminated our fixed-to-fixed cross-currency interest rate swaps, accounted for as net investment hedges, and received net proceeds of $14.7 million. The proceeds are presented within cash provided by investing activities within the consolidated statement of cash flows. The $14.7 million gain is reported as a component of the CTA within AOCI on the consolidated balance sheet. Gains from net investment hedges are reclassified to earnings only when the related CTA are required to be reclassified, usually upon the sale or liquidation of the investment (i.e., the legal entity).

The fair value of our net investment hedge was a net asset (liability) of zero at December 31, 2023 and 2022. During the years ended December 31, 2023, 2022, and 2021, we recognized net interest income associated with this financial instrument of zero, $1.1 million, and $0.5 million, respectively.

## Cash Flow Hedges

## Foreign Currency Exchange Risk Management

We manufacture and sell our products in several countries throughout the world and thus, we are exposed to changes in foreign currency exchange rates. To manage the volatility relating to these exposures, we net the exposures on a consolidated basis to take advantage of natural offsets. To manage the remaining exposure, from time to time, we utilize forward currency exchange contracts and zero cost collar option contracts to minimize the volatility to earnings and cash flows resulting from the effect of fluctuating foreign currency exchange rates on export sales denominated in foreign currencies (principally the euro). These contracts are generally designated as cash flow hedges. As of December 31, 2023, open foreign currency exchange contracts hedge forecasted transactions until June 2024. Designated cash flow hedges entered to minimize foreign currency exchange risk of forecasted revenue transactions are recorded to Net sales on the consolidated statement of operations when the forecasted transaction occurs. As of December 31, 2023, there were $4.0 million in open foreign currency derivative contracts. The fair value of the designated foreign currency hedge contracts was an asset (liability) of zero and $(0.5) million as of December 31, 2023 and 2022, respectively.

(3) Debt maturing within one year is included within "Notes payable and current maturities of long-term debt" on the consolidated balance sheet.

## Revolving Credit Facility

On June 23, 2022, we entered into an Amendment and Restatement Agreement (the “Amendment”) together with the other parties named therein, which amends and restates our existing credit agreement, dated as of March 7, 2016, as amended, supplemented or otherwise modified.

Among other things, the Amendment (a) extends the maturity date from October 28, 2025 to June 23, 2027 and increases the aggregate principal amount of revolving commitments thereunder from $500 million to $1 billion, (b) adds Ingevity UK as a borrower under the revolving credit facility, and (c) modifies certain leverage ratio tests and thresholds.

Borrowings under the revolving credit facility bear interest at a rate per annum equal to either (a) the Secured Overnight Financing Rate ("SOFR"), subject to a zero floor, or (b) a base rate, in each case, plus an applicable margin of 1 percent to 1.75 percent for term benchmark loans and 0.00 percent to 0.75 percent for base rate loans. The weighted average interest rate associated with our revolving credit facility was 6.36 percent and 3.99 percent for the periods ended December 31, 2023, and 2022, respectively. There were no borrowings associated with our revolving credit facility as of December 31, 2021.

Fees of zero, $3.0 million, and zero were incurred in 2023, 2022, and 2021, respectively, to secure the various amendments associated with our revolving credit facility. These fees have been deferred and will be amortized over the term of the facility.

## Term Loan Repayment

During 2022, we repaid our outstanding term loan in an aggregate principal amount of $323.0 million. Upon repayment, we recognized $1.3 million in outstanding interest and $0.4 million in repayment fees and accelerated the remaining deferred finance fees of $0.4 million. The interest, fees, and accelerated deferred finance fees were recorded to Interest expense on the consolidated statements of operations. Legal expenses associated with this repayment have been recorded as incurred.

## Senior Notes

## Senior Note due 2026

On April 27, 2022, we redeemed the $300 million outstanding aggregate principal balance of our 4.50% Senior Notes due in 2026 prior to maturity. The redemption was primarily funded utilizing the outstanding capacity under our revolving credit facility. At redemption, we recognized a $3.4 million redemption premium and accelerated the remaining deferred finance fees of $2.7 million. Both the redemption premium and accelerated deferred finance fees were recorded to Interest expense on the consolidated statements of operations. Legal expenses associated with this redemption have been recorded as incurred.

## Senior Note due 2028

On October 28, 2020, we issued $550 million aggregate principal amount of 3.88% senior unsecured notes due 2028 (the “2028 Notes”). The 2028 Notes were issued pursuant to an indenture dated as of October 28, 2020, by and among Ingevity, the subsidiary guarantors party thereto and U.S. Bank National Association, as trustee. The net proceeds from the sale of the 2028 Notes, after deducting deferred financing fees of $8.8 million, were used to repay the existing term loan and the outstanding balances under our revolving credit facility. Interest payments on the 2028 Notes are due semiannually in arrears on November 1st and May 1st of each year, at a rate of 3.88 percent per year. The 2028 Notes mature on November 1, 2028.

## Accounts Receivable Securitization

On October 2, 2023, we entered into a revolving accounts receivable securitization facility (“Facility”). The Facility enables us to borrow, on a revolving basis, up to a maximum of $100.0 million based upon eligible trade receivables. The Facility expires in October 2024, unless renewed by the mutual consent of the parties. The program's effective borrowing cost is based upon an asset-backed commercial paper conduit rate plus a negotiated margin. In addition, a fee is assessed for any undrawn portion of the facility. The Facility required the establishment of a bankruptcy-remote special purpose entity (“SPE”), wholly owned and fully consolidated by Ingevity Corporation. Trade receivables will be sold to this SPE and held as secured collateral for the borrowings under the Facility. Ingevity maintains continuing involvement as it acts as the servicer for the eligible trade receivables and guarantees payment to the bank. Such receivables, recorded on the consolidated balance sheet, totaled $81.3 million as of December 31, 2023. The borrowings will be presented on the consolidated balance sheet as short-term debt, and cash flows will be presented as financing on our cash flow statement. Fees of $0.4 million were incurred in 2023 to secure the Facility. These fees have been deferred and will be amortized over the term of the Facility. The interest rate associated with our accounts receivable securitization program was 5.61 percent for the period ended December 31, 2023.

## Debt Covenants

Our indentures contain certain customary covenants (including covenants limiting Ingevity's and its restricted subsidiaries' ability to grant or permit liens on certain property securing debt, declare or pay dividends, make distributions on or repurchase or redeem capital stock, make investments in unrestricted subsidiaries, engage in sale and lease-back transactions, and engage in a consolidation or merger, or sell, transfer or otherwise dispose of all or substantially all of the assets of Ingevity and our restricted subsidiaries, taken as a whole) and events of default (subject in certain cases to customary exceptions, as well as grace and cure periods). The occurrence of an event of default under the 2028 Senior Notes could result in the acceleration of the note of such series and could cause a cross-default resulting in the acceleration of other indebtedness of Ingevity and its subsidiaries. We were in compliance with all covenants under the indenture as December 31, 2023.

The credit agreements governing our revolving credit facility contain customary default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-compliance with covenants and cross-defaults to other material indebtedness. The occurrence of an uncured event of default under the credit agreement could result in all loans and other obligations becoming immediately due and payable and our revolving credit facility being terminated. The credit agreement also contains certain customary covenants, including financial covenants. The revolving credit facility financial covenants require Ingevity to maintain on a consolidated basis a maximum total net leverage ratio of 4.0 to 1.0 (which may be increased to 4.5 to 1.0 under certain circumstances) and a minimum interest coverage ratio of 3.0 to 1.0. As calculated per the credit agreement, our net leverage for the four consecutive quarters ended December 31, 2023 were 2.5 and our actual interest coverage for the four consecutive quarters ended December 31, 2023 was 6.2. We were in compliance with all covenants at December 31, 2023.

## Note 11: Share-based Compensation

## Equity Incentive Plan

The Ingevity Corporation 2016 Omnibus Incentive Plan, adopted on May 15, 2016, grants certain corporate officers, key employees, and non-employee directors of Ingevity and subsidiaries different forms of benefits, including stock options, RSU, DSU, and PSU. The Ingevity Corporation 2016 Omnibus Incentive Plan has a maximum shares reserve of 4,000,000 for the grant of equity awards. As of December 31, 2023, 2,066,651 shares under the Ingevity Corporation 2016 Omnibus Incentive Plan are still available to be granted, assuming that Ingevity performs at the target performance level in each year of the three-year performance period for PSU awards. The Talent and Compensation Committee of Ingevity's Board of Directors ("Compensation Committee") determines the long-term incentive mix, including stock options, RSUs, and PSUs, and may authorize new grants annually. We typically issue new common shares for the vesting of awards under our equity incentive plan.

## Employee Stock Purchase Plan

On December 9, 2016, our Compensation Committee and Board of Directors approved the 2017 Ingevity Corporation Employee Stock Purchase Plan ("ESPP"), which was approved by Ingevity's stockholders on April 27, 2017. The ESPP allows eligible employee participants to purchase no more than 5,000 shares of our common stock at a discount through payroll deductions up to 15 percent of their compensation deducted during the purchase period. However, no participant shall be permitted to purchase common stock with a value greater than $25,000 in any calendar year. The ESPP is a tax-qualified plan under Section 423 of the Internal Revenue Code. The ESPP consists of a one-month enrollment period preceding the three-month purchase period. Employees purchase shares in each purchase period at 85 percent of the market value of our common stock at either the beginning of the offering period or the end of the purchase period, whichever price is lower.

On April 27, 2023, the ESPP was amended to add an additional 300,000 shares of Ingevity's common stock, increasing the total amount of shares under the ESPP to 550,000 shares, those additional shares were registered with the SEC on May 4, 2023. The shares are reserved and authorized for issuance to participating U.S. employees, as defined by the ESPP, excluding certain officers of Ingevity. We typically issue treasury shares for issuances under the ESPP. As of December 31, 2023, 319,611 shares under the ESPP are still available for issuance. During fiscal year 2023, there were 34,036 shares issued under the ESPP at an average price of $55.82. All purchases under the ESPP were suspended during the third quarter of 2023.

Our share-based compensation and ESPP expense is included in the table below.

## Stock Options

All stock options vest in accordance with vesting conditions set by the Compensation Committee. The Compensation Committee, with the addition of rTSR to the PSUs, did not grant stock options in 2023. Stock options granted to date have vesting periods of one to three years from the date of grant. Incentive and non-qualified options granted under the Plan expire no later than 10 years from the grant date. Expense related to stock options granted is based on the assumptions shown in the table below:

<table><tr><td rowspan="2">Weighted-average assumptions used to calculate expense for stock options</td><td colspan="3">Years Ended December 31,</td></tr><tr><td>2023</td><td>2022</td><td>2021</td></tr><tr><td>Risk-free interest rate</td><td>— %</td><td>1.8 %</td><td>1.0 %</td></tr><tr><td>Average life of options (years)</td><td>0.0</td><td>6.0</td><td>6.5</td></tr><tr><td>Volatility</td><td>— %</td><td>40.0 %</td><td>46.0 %</td></tr><tr><td>Dividend yield</td><td>—</td><td>—</td><td>—</td></tr><tr><td>Fair value per stock option</td><td>$ —</td><td>$ 28.80</td><td>$ 33.07</td></tr></table>

The following table summarizes Ingevity's stock option activity.

<table><tr><td></td><td>Number of Options (in thousands)</td><td>Weighted-average exercise price (per share)</td><td>Weighted-average remaining contractual term (years)</td><td>Aggregate intrinsic value (in thousands)</td></tr><tr><td>Outstanding, December 31, 2022</td><td>335</td><td>$ 63.18</td><td>6.1</td><td>$ 4,100</td></tr><tr><td>Granted</td><td>—</td><td>—</td><td></td><td></td></tr><tr><td>Exercised</td><td>(43)</td><td>52.67</td><td></td><td></td></tr><tr><td>Forfeited</td><td>(14)</td><td>80.49</td><td></td><td></td></tr><tr><td>Cancelled</td><td>—</td><td>—</td><td></td><td></td></tr><tr><td>Outstanding, December 31, 2023</td><td>278</td><td>$ 63.86</td><td>5.1</td><td>$ 863</td></tr><tr><td>Exercisable, December 31, 2023</td><td>227</td><td>$ 62.78</td><td>4.5</td><td>$ 863</td></tr></table>

The aggregate intrinsic values in the table above represent the total pre-tax intrinsic value (the difference between Ingevity's closing stock price on the last trading day of the period and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their in-the-money options at each year end. The amount changes based on the fair market value of Ingevity's stock.

As of December 31, 2023, $0.3 million of total unrecognized compensation expense related to stock options is expected to be recognized over a weighted-average period of 0.5 years.

## Restricted Stock Units, Deferred Stock Units, and Performance-based Restricted Stock Units

All RSUs, DSUs, and PSUs vest in accordance with vesting conditions set by the Compensation Committee. RSUs and DSUs granted to date have vesting periods ranging from less than one year to three years from the date of grant. PSUs granted to date have vesting periods of three years from the date of grant, including grants that have a cumulative three-year performance period, subject to the satisfaction of the applicable performance goals established for the respective grant. We periodically assess the probability of achievement of the performance criteria and adjust the amount of compensation expense accordingly. Beginning in 2023, certain granted PSUs include a rTSR modifier that, when combined with the performance criteria could modify the final PSU payout by +/- 15 percent depending on the Company's rTSR performance over a three year performance period. The rTSR component of the 2023 PSU awards is a market condition requiring the use of a Monte Carlo simulation on the grant date to estimate the fair value. The assumptions utilized to calculate the fair value of the 2023 PSUs are shown in the table below. Compensation expense is recognized over the vesting period and adjusted for the probability of achievement of the performance criteria.

## Share Repurchases

On July 25, 2022, our Board of Directors authorized the repurchase of up to $500.0 million of our common stock (the "2022 Authorization"), and rescinded the prior outstanding repurchase authorization with respect to the shares that remained unused under the prior authorization. Shares under the current repurchase authorization may be purchased through open market or privately negotiated transactions at the discretion of management based on its evaluation of market prevailing conditions and other factors, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended.

During the year ended December 31, 2023, we repurchased $92.1 million (inclusive of $0.8 million in excise tax) in common stock, representing 1,269,373 shares of our common stock at a weighted average cost per share of $71.93. At December 31, 2023, $353.4 million remained unused under our Board-authorized repurchase program. During the year ended December 31, 2022 and 2021, we repurchased $145.2 million and $109.4 million in common stock, representing 2,112,463 and 1,421,379 shares of our common stock at a weighted average cost per share of $68.73 and $76.98, respectively.

(1) Operating lease assets, net are recorded net of accumulated amortization of $40.7 million and $40.8 million as of December 31, 2023, and 2022, respectively.

(2) Finance lease assets, net are recorded net of accumulated amortization in Property, plant, and equipment, net and Other assets, net of $78.4 million and $1.5 million, as of December 31, 2023, and $73.8 million and $1.4 million, as of December 31, 2022.

(3) Operating lease liabilities include $0.5 million and $0.2 million of accrued interest, as of December 31, 2023 and 2022, respectively.

## Finance Leases

Our finance lease obligations of $101.1 million, and $101.9 million at December 31, 2023 and 2022, respectively, primarily consist of two leases. The first obligation of $80.0 million, at December 31, 2023, is owed to the city of Wickliffe, Kentucky, associated with Performance Materials' Wickliffe, Kentucky, manufacturing site, which is due at maturity in 2027. This obligation will be settled upon maturity utilizing liquid assets that have been placed into a trust established strictly for this purpose. The trust is presented as Restricted investment on the consolidated balance sheet in the amount of $79.1 million as of December 31, 2023, see Note 5 for more information. The remaining obligation of $20.9 million, at December 31, 2023, is primarily owed to the lessor of our corporate headquarters in North Charleston, South Carolina. The lease commenced in July 2020, with a term of 15 years, and is structured as a traditional rental with payments due on a monthly basis.

We also have a finance lease obligation due in 2031 for certain assets located at our Performance Materials' Waynesboro, Georgia, manufacturing facility. The lease is with the Development Authority of Burke County (“Authority”). The Authority established the sale-leaseback of these assets by issuing an industrial development revenue bond. The bond was purchased by Ingevity and the obligations under the finance lease remain with Ingevity. Accordingly, we offset the finance lease obligation and bond on our consolidated balance sheets.

## Note 14: Retirement Plans

## Defined Contribution Plans

Eligible employees may participate in our retirement savings plan ("Plan"), a qualified salary-reduction plan under Section 401(k) of the U.S. Internal Revenue Code by contributing a portion of their compensation. For non-union eligible employees participating in the Plan, Ingevity makes matching contributions up to six percent of the employee deferral. In addition to the matching contributions, Ingevity also makes a non-elective contribution of three percent of eligible compensation per payroll for non-union employees. For eligible union employees participating in the Plan, Ingevity makes matching contributions up to 100 percent of the first three percent of the employee deferrals and 50 percent on the next two percent of deferrals. Employee contributions, as well as Ingevity's match contributions, are made to funds designated by the participant, none of which are based on Ingevity's common stock.

Charges associated with employer contributions to the Plan were $11.4 million, $11.2 million, and $9.5 million for the years ended December 31, 2023, 2022, and 2021, respectively.

## Defined Benefit Pension and Postretirement Plans

Ingevity has both established qualified and non-qualified benefit plans to provide pension and post-retirement benefits to certain employees and retirees. Our retirement obligations consist of accrued defined benefit obligations earned by Ingevity domestic hourly union employees; accrued obligations from a frozen non-qualified defined benefit pension plan for certain salaried and former salaried employees of Ingevity; and other post-retirement medical and life insurance benefits.

We are required to recognize on our consolidated balance sheets the overfunded and underfunded status of our defined benefit postretirement plans. The overfunded and underfunded status is defined as the difference between the fair value of plan assets and the projected benefit obligation. We are also required to recognize, as a component of other comprehensive income, the actuarial gains and losses and the prior service costs and credits that arise during the period.

(1) The discount rate used to calculate pension and other post-retirement obligations was based on a review of available yields on high-quality corporate bonds. In selecting a discount rate, we placed particular emphasis on a discount rate yield-curve provided by our third-party actuary, which takes into consideration the projected cash flows that represent the expected timing and amount of our plans' benefit payments.

(2) Amounts are recorded to "Cost of sales" on our consolidated statements of operations consistent with the employee compensation costs that participate in the plan.

(3) Amounts are recorded to "Other (income) expense, net" on our consolidated statements of operations.

(4) Our pension and postretirement settlement and curtailment (income) charges are related to the acceleration of prior service costs as a result of a reduction in the number of participants within the Union Hourly defined benefit pension plan during 2022.

## Contributions

We made a $2.0 million voluntary cash contribution to our domestic hourly union defined benefit pension plan during the year ended December 31, 2023. There were no voluntary cash contributions to our domestic hourly union defined benefit pension plan in the years ended December 31, 2022, and 2021. The minimum required contribution to our domestic hourly union defined benefit plan for fiscal year 2024 is $0.2 million.

## Fair Value Hierarchy

Following is a description of the valuation methodologies used for the investment measure at fair value. See Note 5 for the definition of fair value and the descriptions of Level 1, 2, and 3 in the fair value hierarchy.

- Cash and short-term funds — Cash and quoted short-term instruments are valued at the closing price or the amount held on deposit by the custodian bank.

- Mutual Funds — Mutual funds are valued at the closing price reported on the major market on which the individual securities are traded. Substantially all mutual funds are classified within Level 1 of the valuation hierarchy.

- Pooled Funds — These investment vehicles are valued using the Net Asset Value (NAV) provided by the fund administrator. The NAV is based on the value of the underlying assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding.

- Other — Other assets are represented by investments in a series limited partnership. These assets are not actively traded and are classified as Level 2.

## Estimated Future Benefit Payments

The following table reflects the estimated future benefit payments for our pension and other postretirement benefit plans. These estimates take into consideration expected future service, as appropriate.

<table><tr><td>In millions</td><td>Pensions</td><td>Other Benefits</td></tr><tr><td>2024</td><td>$     1.2</td><td>$     0.1</td></tr><tr><td>2025</td><td>1.3</td><td>0.1</td></tr><tr><td>2026</td><td>1.5</td><td>0.1</td></tr><tr><td>2027</td><td>1.6</td><td>0.1</td></tr><tr><td>2028</td><td>1.8</td><td>0.1</td></tr><tr><td>2029-2033</td><td>11.0</td><td>0.3</td></tr></table>

## Sensitivity Analysis

A one-half percent increase in the assumed discount rate would have decreased our qualified pension benefit obligations by $2.2 million at December 31, 2023 and decreased our qualified pension benefit costs by $0.1 million for 2023. A one-half percent decrease in the assumed discount rate would have increased our qualified pension obligations by $2.4 million at December 31, 2023 and increased our qualified pension benefit cost by $0.1 million for 2023.

A one-half percent increase in the assumed expected long-term rate of return on plan assets would have decreased our qualified pension costs by $0.1 million for 2023. A one-half percent decrease in the assumed expected long-term rate of return on plan assets would have increased our qualified pension costs by $0.1 million for 2023.

(1) Primarily represents costs associated with contract terminations, plant and equipment decommissioning charges and other miscellaneous exit costs.

(2) Primarily represents property, plant and equipment and finite-lived intangible asset write-downs, accelerated depreciation and amortization, and impairment charges on certain assets, which were or are to be disposed of or abandoned. Also included, to the extent incurred, the acceleration effect of re-estimating settlement dates and revised cost estimates associated with asset retirement obligations related to asset disposal charges that are included within restructuring charges.

(3) During 2023, we incurred severance and asset charges associated with targeted workforce reduction initiatives.

Throughout 2023 we initiated several measures across the organization to pursue greater cost efficiency which included a reorganization to streamline certain functions and reduce ongoing costs. On November 1, 2023 we announced a number of strategic actions designed to further reposition our Performance Chemicals reportable segment to improve the profitability and reduce the cyclicality of the Company as a whole. These actions increase our focus on growing our most profitable Performance Chemicals' product lines such as road technologies and accelerate our transition to non-crude tall oil ("CTO") based fatty acids. This initiative will result in the reduction, and in some cases exit, of certain historical end-use markets of our industrial specialties product line such as adhesives, publication inks, and oilfield, representing approximately $300.0 million of net sales. The announced actions include the permanent closure of our Performance Chemicals' CTO refinery and the closure of our manufacturing plant located in DeRidder, Louisiana (the "DeRidder Plant"), including the polyol production assets associated with the Advance Polymer Technologies reportable segment, as well as additional corporate and business cost reduction actions. We expect to close the DeRidder Plant by the end of the first half of 2024. These actions are referred to as Performance Chemicals' repositioning.

The Performance Chemicals' repositioning, when combined with earlier targeted workforce reduction initiatives, during 2023 resulted in the reduction of Ingevity's global workforce by almost 20 percent, 25 percent of these reductions being employees directly associated with commercial sales activities of the soon-to-be exited and/or reduced end-use markets of our industrial specialties product line. Specific to Performance Chemicals, the reduction represented approximately 30 percent of the reportable segment's workforce. The collective actions of workforce, operational, and regional business exits, we believe, will hinder our ability to dispose of the associated inventory on hand, as of December 31, 2023. As a result, we have recorded $19.7 million of non-cash, lower of cost or market, inventory charges to adjust the carrying value of the impacted inventory to what we will realize upon disposal, less disposal costs. These inventory charges are recorded to Cost of sales on the consolidated statement of operations. Since these inventory charges are directly attributable to the Performance Chemicals'

repositioning, that is, they do not represent normal, recurring expenses necessary to operate our business, we have combined these charges with the restructuring charges, noted above, and have excluded such impact from the financial results of our Performance Chemicals reportable segment, refer to Note 19 for more information.

We expect to incur aggregate charges of approximately $280.0 million associated with the Performance Chemicals' repositioning, consisting of approximately $180.0 million in asset-related charges, approximately $15.0 million in severance and other employee-related costs, and approximately $85.0 million in other restructuring costs including decommissioning, dismantling and removal charges, and contract termination costs. We expect approximately $180.0 million of the total charges to be non-cash. The majority of non-cash charges and 50-60 percent of cash charges are expected to be recognized in 2024. Due to the DeRidder Plant closure and the corresponding reduced CTO refining capacity, we may be obligated, under an existing CTO supply contract, to purchase CTO volumes through 2025 at amounts in excess of required CTO volumes. We intend to manage our CTO volumes by reselling excess volumes (herein referred to as "CTO resales") in the open market. Excluded from the estimated $280.0 million of estimated aggregate charges are potential costs we may incur associated with the CTO resales which, based on what we believe to be market rates today, may result in $30.0 million to $80.0 million of incremental losses in 2024. Refer to Note 2, under the section: Non-operating income and expense, for more information.

During the year ended December 31, 2023, we incurred $5.1 million in cash charges and $127.7 million in non-cash charges related to the strategic actions initiated during the fourth quarter of 2023.

The charges we currently expect to incur in connection with these actions are subject to a number of assumptions and risks, and actual results may differ materially. We may also incur other material charges not currently contemplated due to events that may occur as a result of, or in connection with, these actions.

## Other (income) charges, net

## Alternative feedstock transition

In April 2023, we implemented the feedstock transition of our Crossett, Arkansas manufacturing plant (“Crossett”). This transition converted Crossett from a CTO-based feedstock production facility to produce fatty acids from alternative plant-based feedstocks. During the year ended December 31, 2023, we incurred $22.1 million in costs, including $8.8 million in asset disposal costs.

## North Charleston plant transition

Our North Charleston, South Carolina Performance Chemicals manufacturing plant has historically been co-located with a WestRock Company (“WestRock”) paper mill. In May 2023, WestRock announced that it would permanently cease operating its North Charleston paper mill by August 31, 2023 and notified us that it was terminating the shared services in accordance with our operating agreement. WestRock ceased production at their North Charleston paper mill in June 2023. During 2023, we executed a transition plan to separate certain critical operating services WestRock had historically provided to us such as steam, water and wastewater treatment. During the year ended December 31, 2023, we incurred $14.8 million of expense, including $4.3 million in asset disposal costs. We expect to incur an additional $3-5 million of costs as we complete this transition in the first half of 2024.

## Business transformation costs

We embarked upon a business transformation initiative that included the implementation of an upgraded enterprise resource planning ("ERP") system. The implementation of our new ERP system occurred in multiple phases beginning with our pilot deployment in the first quarter of 2022 and concluded with our final deployment in the first quarter of 2023. This business transformation initiative concluded in the fourth quarter of 2023. Costs incurred, during the years ended December 31, 2023, 2022, and 2021, of $7.7 million, $13.8 million, and $16.1 million, respectively, represent costs directly associated with the business transformation initiative that, in accordance with GAAP, could not be capitalized.

## Note 16: Acquisitions

## Ozark Materials

On October 3, 2022, we completed our acquisition of Ozark Materials, LLC ("OM"), and Ozark Logistics, LLC ("OL" and, together with OM, "Ozark Materials"), pursuant to that certain Equity Purchase Agreement (the "Purchase Agreement"), by and among Ingevity, Ozark Materials and Ozark Holdings, Inc. ("Seller"). In accordance with the Purchase Agreement, we acquired from Seller, all of the issued and outstanding limited liability company membership interests of Ozark Materials for a purchase price of $325.0 million, subject to customary adjustments for working capital, indebtedness and transaction expenses (the "Acquisition"). The Acquisition has been integrated into our Performance Chemicals segment and is included within our road technologies product line. We funded the Acquisition through a combination of borrowings under our existing credit facilities and cash on hand.

The Acquisition is not considered significant to our Consolidated Financial Statements for the year ended December 31, 2023; therefore, proforma results of operations have not been presented.

## Purchase Price Allocation

Ozark Materials is considered an acquisition of a business under business combinations accounting guidance, and therefore we applied acquisition accounting. Acquisition accounting requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The aggregate purchase price noted above was allocated to the major categories of assets acquired and liabilities assumed based upon their estimated fair values at the acquisition date using primarily Level 2 and Level 3 inputs. These Level 2 and Level 3 valuation inputs include an estimate of future cash flows and discount rates. Additionally, estimated fair values are based, in part, upon outside appraisals for certain assets, including specifically-identified intangible assets. See Note 5 for an additional explanation of Level 2 and Level 3 inputs. We finalized the purchase price allocation in the third quarter of 2023, with no material adjustments recorded.

(1) Fair value of finished goods inventories acquired included a step-up in the value of $1.8 million, of which $0.9 million was expensed during each of the years ended December 31, 2023 and December 31, 2022, respectively. The expense is included within "Cost of sales" on the consolidated statement of operations. Inventories are accounted for on a FIFO basis of accounting.

(2) The aggregate amortization expense was $10.9 million for the year ended December 31, 2023. Estimated amortization expense is as follows: 2024 - $10.9 million, 2025 - $10.7 million, 2026 - $10.0 million, 2027 - $10.0 million, and 2028 - $10.0 million.

(3) Goodwill largely consists of expected cost synergies and economies of scale resulting from the business combination. We expect the full amount to be deductible for income tax purposes. This acquired goodwill has been included within our Performance Chemicals reporting unit. See Note 8 for further information regarding our allocation of goodwill among our reporting segments.

(1) GILTI is defined as Global Intangible Low Tax Income

The increase in our effective tax rate from 2022 to 2023 was mainly driven by the mix of earnings, with U.S. losses, primarily due to the restructuring activities during the year (see Note 15), driving an overall global loss and tax benefit for the year. Furthermore, significant decline in U.S. taxable earnings drove a decrease in the foreign derived intangible income benefit as compared to prior years skewing the effective tax rate.

The decrease in our effective tax rate from 2021 to 2022 was primarily driven by the recognition of the UK's six percent legislative rate increase in 2021. During 2022, our effective tax rate benefited from reduced taxes at our China manufacturing plant associated with the purchases of our sustainably sourced raw material feedstock. This reduction was partially offset by an increase in foreign earnings deemed taxable in the U.S. mainly due to final U.S. foreign tax credit regulations modifying the definition of what foreign taxes qualify as creditable taxes, denying Brazilian taxes paid as qualifying taxes.

(1) Presentation in the table above is on a gross basis, however, due to jurisdictional netting, our net deferred tax asset and liability recorded on the consolidated balance sheets is $11.6 million and $70.9 million, respectively, as of December 31, 2023, and $5.7 million and $106.5 million, respectively, as of December 31, 2022.

Our net deferred tax liability decreased $41.5 million at December 31, 2023 as compared to December 31, 2022. As part of Tax Cuts and Jobs Act ("TCJA") enacted in December 2017 under Internal Revenue Code ("IRC") Section 174, beginning in 2022 we were required to capitalize and amortize research and experimental expenditures. This requirement continued to increase the deferred tax asset for 2023. Also as modified by TCJA, IRC Section 163(j) limits U.S. business interest expense deductions as a function of adjusted taxable income. In 2023 due to a reduction in taxable income, Ingevity was subject to these limitations creating a new deferred tax asset for 2023, labeled above as interest limitation. The increase in the LIFO reserve in 2023 flipped our 2022 deferred tax liability to a deferred tax asset in 2023. Further acceleration of book amortization on intangibles drove a decline in the overall deferred tax liability for the year.

We have deferred tax assets, including net operating loss and state tax credit carryforwards, which are available to offset future taxable income. A valuation allowance has been provided where management has determined that it is more likely than not that the deferred tax assets will not be realized. In 2023, we recognized tax expense of $1.3 million due to our expected inability to recognize the benefit associated with state tax credits prior to their expiration.

At December 31, 2023, foreign net operating loss carryforwards totaled $32.9 million; of this total, $0.1 million will expire in 1 year and $32.8 million has no expiration date.

Due to the global nature of our operations, a portion of our cash is held outside the U.S. The cash and cash equivalent balance at December 31, 2023 included $90.7 million held by our foreign subsidiaries. At December 31, 2023, 2022, and 2021, no deferred income taxes have been provided for our share of undistributed net earnings of foreign operations due to management’s intent to reinvest such amounts indefinitely. The determination of the amount of taxes that may be due if

earnings are remitted is not practicable because such liability, if any, is dependent on circumstances that exist if and when remittance occurs. The circumstances that would affect the calculations include the source location and amount of the distribution, the underlying tax rate already paid on the earnings, foreign withholding taxes, the opportunity to use foreign tax credits, and the potential impact of future tax reform. Positive undistributed earnings considered to be indefinitely reinvested totaled $90.0 million at December 31, 2023.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:

As of December 31, 2023, 2022, and 2021, $1.4 million, $0.9 million, and $0.4 million, respectively, of unrecognized tax benefit, including penalties and interest, would, if recognized, impact our effective tax rate. We recognize interest accrued related to unrecognized tax benefits and penalties as income tax expense.

On July 19, 2018, we filed suit against BASF Corporation (“BASF”) in the United States District Court for the District of Delaware (the “Delaware Proceeding”) alleging BASF infringed Ingevity’s patent covering canister systems used in the control of automotive gasoline vapor emissions (U.S. Patent No. RE38,844) (the “844 Patent”). On February 14, 2019, BASF asserted counterclaims against us in the Delaware Proceeding, alleging two claims for violations of U.S. antitrust law (one for exclusive dealing and the other for tying) as well as a claim for tortious interference with an alleged prospective business relationship between BASF and a BASF customer (the “BASF Counterclaims”). The BASF Counterclaims relate to our enforcement of the 844 Patent and our entry into several supply agreements with customers of its fuel vapor canister honeycombs. The U.S. District Court dismissed our patent infringement claims on November 18, 2020, and the case proceeded to trial on the BASF Counterclaims in September 2021.

On September 15, 2021, a jury in the Delaware Proceeding issued a verdict in favor of BASF on the BASF Counterclaims and awarded BASF damages of approximately $28.3 million, which will be trebled under U.S. antitrust law to approximately $85.0 million. On May 18, 2023, the court in the Delaware Proceeding entered judgment on the jury’s verdict, which commenced the post-trial briefing stage. On February 13, 2024, the court in the Delaware Proceeding denied BASF’s motion for pre-judgment interest on its tortious interference claim as well as and our motion seeking judgment as a matter of law, or a new trial in the alternative. In addition, BASF has indicated it will seek attorneys’ fees and costs in amounts that they will allege and have to demonstrate at a future date. Unless the judgment is set aside, BASF will be entitled to post-judgment interest pursuant to the rate provided under federal law.

We disagree with the verdict, including the court’s application of the law and entry of judgment, and intend to appeal. In addition, we may challenge the U.S. District Court’s November 2020 dismissal of our patent infringement claims against BASF. Ingevity believes in the strength of its intellectual property and the merits of its position and intends to pursue all legal relief available to challenge these outcomes in the Delaware Proceeding. Final resolution of these matters could take up to 24 months.

As of December 31, 2023, nothing has occurred in the post-trial proceedings to warrant any change to our conclusions as disclosed within our 2022 Annual Report. The full amount of the trebled jury verdict, $85.0 million, is accrued within Other liabilities on the consolidated balance sheet as of December 31, 2023 and the charge was included within Other (income) expense, net on the consolidated statement of operations for the year ended December 31, 2021. In addition, as a result of the judgment being officially entered on May 18, 2023, we have started accruing for post-judgment interest at the legally mandated interest rate. The amount of any liability we may ultimately incur could be more or less than the amount accrued.

## Note 19: Segment Information

## Segment change

As described in Note 1, effective in the first quarter of 2023, we separated our engineered polymers product line from the Performance Chemicals reportable segment into its own reportable segment, Advanced Polymer Technologies. We have recast the data below to reflect the changes in our reportable segments to conform to the current year presentation.

Ingevity’s operating segments are (i) Performance Materials, (ii) Performance Chemicals, and (iii) Advanced Polymer Technologies. A description of our operating segments is included in Note 1.

<table><tr><td rowspan="2">In millions</td><td colspan="4">Years Ended December 31,</td></tr><tr><td>2023</td><td>2022</td><td>2021</td><td></td></tr><tr><td>Net sales</td><td></td><td></td><td></td><td></td></tr><tr><td>Performance Materials</td><td>$     586.0</td><td>$     548.5</td><td>$     516.8</td><td></td></tr><tr><td>Performance Chemicals</td><td>902.1</td><td>875.1</td><td>688.9</td><td></td></tr><tr><td>Advanced Polymer Technologies</td><td>204.0</td><td>244.7</td><td>185.8</td><td></td></tr><tr><td>Total net sales  \( {}^{(1)} \)</td><td>$     1,692.1</td><td>$     1,668.3</td><td>$     1,391.5</td><td></td></tr><tr><td>Segment EBITDA  \( {}^{(2)} \)</td><td></td><td></td><td></td><td></td></tr><tr><td>Performance Materials</td><td>$     286.6</td><td>$     252.2</td><td>$     249.4</td><td></td></tr><tr><td>Performance Chemicals</td><td>65.7</td><td>160.4</td><td>140.5</td><td></td></tr><tr><td>Advanced Polymer Technologies</td><td>44.5</td><td>40.0</td><td>32.3</td><td></td></tr><tr><td>Total Segment EBITDA  \( {}^{(2)} \)</td><td>$     396.8</td><td>$     452.6</td><td>$     422.2</td><td></td></tr><tr><td>Interest expense</td><td>(93.3)</td><td>(61.8)</td><td>(51.7)</td><td></td></tr><tr><td>Interest income</td><td>6.3</td><td>7.5</td><td>4.0</td><td></td></tr><tr><td>(Provision) benefit for income taxes</td><td>4.7</td><td>(58.0)</td><td>(44.7)</td><td></td></tr><tr><td>Depreciation and amortization - Performance Materials</td><td>(38.3)</td><td>(36.1)</td><td>(36.8)</td><td></td></tr><tr><td>Depreciation and amortization - Performance Chemicals</td><td>(53.2)</td><td>(43.1)</td><td>(40.0)</td><td></td></tr><tr><td>Depreciation and amortization - Advanced Polymer Technologies</td><td>(31.3)</td><td>(29.6)</td><td>(33.1)</td><td></td></tr><tr><td>Restructuring and other income (charges), net  \( {}^{(3)(9)} \)</td><td>(189.9)</td><td>(13.8)</td><td>(16.2)</td><td></td></tr><tr><td>Acquisition and other-related income (costs), net  \( {}^{(4)} \)</td><td>(4.5)</td><td>(5.9)</td><td>(0.6)</td><td></td></tr><tr><td>Loss on CTO resales  \( {}^{(5)} \)</td><td>(22.0)</td><td>—</td><td>—</td><td></td></tr><tr><td>Gain (loss) on sale of strategic investment  \( {}^{(6)} \)</td><td>19.3</td><td>—</td><td>—</td><td></td></tr><tr><td>Litigation verdict charge  \( {}^{(7)} \)</td><td>—</td><td>—</td><td>(85.0)</td><td></td></tr><tr><td>Pension and postretirement settlement and curtailment income (charges), net  \( {}^{(8)} \)</td><td>—</td><td>(0.2)</td><td>—</td><td></td></tr><tr><td>Net income (loss)</td><td>$ (5.4)</td><td>$ 211.6</td><td>$ 118.1</td><td></td></tr></table>

(1) Relates to external customers only, all intersegment sales and related profit have been eliminated in consolidation.

(2) Segment EBITDA is the primary measure used by our chief operating decision maker to evaluate the performance of and allocate resources among our operating segments. Segment EBITDA is defined as segment net sales less segment operating expenses (segment operating expenses consist of costs of sales, selling, general and administrative expenses, research and technical expenses, other (income) expense, net, excluding depreciation and amortization). We have excluded the following items from segment EBITDA: interest expense associated with corporate debt facilities, interest income, income taxes, depreciation, amortization, restructuring and other income (charges), net, including inventory lower of cost or market charges associated with restructuring actions, acquisition and other-related income (costs), litigation verdict charges, gain on sale of strategic investments, loss on CTO resales, pension and postretirement settlement and curtailment income (charges), net.

(3) The table below provides an allocation of these charges between our three reportable segments to provide investors, potential investors, securities analysts and others with the information, should they choose, to apply such (income) charges to each respective reportable segment for which the charges relate.

(5) For the year ended December 31, 2023, charges relates to the Performance Chemicals reportable segment. Refer to Note 2, under the section: Non-operating income and expense, for more information.

(6) For the year ended December 31, 2023, gains related to our Performance Materials reportable segment. We exclude gains and losses from sales of strategic investments from our segment results, as well as our non-GAAP financial measures, because we do not consider such gains or losses to be directly associated with the operational performance of the segment. We believe that the inclusion of such gains or losses, would impair the factors and trends affecting the historical financial performance of our reportable segments. We continue to include undistributed earnings or loss, distributions, amortization or accretion of basis differences, and other-than-temporary impairments for equity method investments that we believe are directly attributable to the operational performance of such investments, in our reportable segment results. Refer to Note 5, under the section: Strategic Investments, for more information.

(7) For the year ended December 31, 2021, litigation verdict charge relates to the Performance Materials segment. Refer to Note 18 for additional information.

(8) For the year ended December 31, 2022 the charges relate to the Performance Materials reportable segment. Our pension and postretirement settlement and curtailment charges (income) are related to the acceleration of prior service costs, as a result of a reduction in the number of participants within the Union Hourly defined benefit pension plan. These are excluded from our segment results because we consider these costs to be outside our operational performance. We continue to include the service cost, amortization of prior service cost, interest costs, expected return on plan assets, and amortized actual gains and losses in our segment EBITDA.

(9) We regularly perform strategic reviews and assess the return on our operations, which sometimes results in a plan to restructure the business. These costs are excluded from our reportable segment results; details of which are included in the table below.

# ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

## ITEM 9A. CONTROLS AND PROCEDURES

The Company maintains a system of disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in the Company's reports filed or submitted under the Securities Exchange Act of 1934, as amended ("Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. These controls and procedures also provide reasonable assurance that information required to be disclosed in such reports is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosures.

As of December 31, 2023, the Company's Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), together with management, conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures pursuant to Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, the CEO and CFO concluded that these disclosure controls and procedures are effective at the reasonable assurance level.

# Non-GAAP Financial Measures Reconciliation

Ingevity has presented certain financial measures, defined below, which have not been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and has provided a reconciliation to the most directly comparable financial measure calculated in accordance with GAAP on the following pages. These financial measures are not meant to be considered in isolation nor as a substitute for the most directly comparable financial measure calculated in accordance with GAAP. Investors should consider the limitations associated with these non-GAAP measures, including the potential lack of comparability of these measures from one company to another.

We believe these non-GAAP financial measures provide management as well as investors, potential investors, securities analysts, and others with useful information to evaluate the performance of the business, because such measures, when viewed together with our financial results computed in accordance with GAAP, provide a more complete understanding of the factors and trends affecting our historical financial performance, liquidity measures, and projected future results. Reconciliations of these non-GAAP financial measures are set forth within the following pages.

The non-GAAP measures referenced herein are (i) Diluted Adjusted Earnings (Loss) Per Share, (ii) Adjusted EBITDA, (iii) Adjusted EBITDA Margin, and (iv) Net Debt Ratio.

Adjusted earnings (loss) is defined as net income (loss) plus restructuring and other (income) charges, net, including inventory lower of cost or market charges associated with restructuring actions, acquisition and other-related (income) costs, pension and postretirement settlement and curtailment (income) charges, loss on CTO resales, gain on sale of strategic investments, debt refinancing fees, litigation verdict charges, and the income tax expense (benefit) on those items, less the provision (benefit) from certain discrete tax items.

Diluted adjusted earnings (loss) per share is defined as diluted earnings (loss) per common share plus restructuring and other (income) charges, net, including inventory lower of cost or market charges associated with restructuring actions, per share, acquisition and other-related (income) costs per share, pension and postretirement settlement and curtailment (income) charges per share, loss on CTO resales per share, gain on sale of strategic investment per share, debt refinancing fees per share, litigation verdict charge per share, and the income tax expense (benefit) per share on those items, less the provision (benefit) from certain discrete tax items per share.

Adjusted EBITDA is defined as net income (loss) plus interest expense, net, provision (benefit) for income taxes, depreciation, amortization, restructuring and other (income) charges, net, including inventory lower of cost or market charges associated with restructuring actions, acquisition and other-related (income) costs, litigation verdict charges, gain on sale of strategic investment, loss on CTO resales, and pension and postretirement settlement and curtailment (income) charges, net.

Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by Net sales.

Net Debt is defined as the sum of notes payable, short-term debt, current maturities of long-term debt, long-term debt including finance lease obligations, and debt issuance costs, less the sum of cash and cash equivalents, restricted cash associated with our new market tax credit financing arrangement, and restricted investment associated with certain finance lease obligations, excluding the allowance for credit losses on held-to-maturity debt securities held within the restricted investment.

Net Debt Ratio is defined as Net Debt divided by last twelve months Adjusted EBITDA, inclusive of acquisition-related pro forma adjustments.

(1) We regularly perform strategic reviews and assess the return on our operations, which sometimes results in a plan to restructure the business. These costs are excluded from our reportable segment results; details of which are included in the table below.

(2) Charges represent (gains) losses incurred to complete and integrate acquisitions and other strategic investments. Charges may include the expensing of the inventory fair value step-up resulting from the application of purchase accounting for acquisitions and certain legal and professional fees associated with the completion of acquisitions and strategic investments.

(1) Included in Cost of sales on the condensed consolidated statement of operations.

(3) Our pension and postretirement settlement and curtailment charges (income) are related to the acceleration of prior service costs, as a result of a reduction in the number of participants within the Union Hourly defined benefit pension plan. These are excluded from our segment results because we consider these costs to be outside our operational performance. We continue to include the service cost, amortization of prior service cost, interest costs, expected return on plan assets, and amortized actual gains and losses in our segment EBITDA.

(4) We exclude litigation verdict charges from our segment results, as well as our non-GAAP financial measures, because we do not consider such charges to be directly associated with the operational performance of the segment. Refer to Note 18, Commitments and Contingencies in the Notes to the Consolidated Financial Statements included in the Company's Annual Report on the Form 10-K for the year ended December 31, 2023.

(5) Represents the acceleration of deferred financing fees, debt extinguishment premium paid and other fees incurred related to our senior note redemption, term loan repayment, revolving credit facility amendment, and termination of certain interest rate swaps during the period ended December 31, 2022. We exclude these costs from our segment results, as well as our non-GAAP financial measures, because we do not consider such costs to be directly associated with the operational performance of our segments or the Company as a whole.

(6) Refer to Note 5, under the section: Strategic Investments, Summary of Significant Accounting Policies in the Notes to the Consolidated Financial Statements included in the Company's Annual Report on the Form 10-K for the year ended December 31, 2023. Due to the DeRidder Plant closure and the corresponding reduced CTO refining capacity, we may be obligated, under an existing CTO supply contract, to purchase CTO through 2025 at amounts in excess of required CTO volumes. We intend to manage our CTO volumes by reselling excess volumes (herein referred to as "CTO resales") in the open market, which, based on what we believe to be market rates today, may result in a loss of $30.0 million to $80.0 million in 2024.

Our Performance Chemicals reportable segment is in the business of producing, primarily from CTO-based feedstocks, derivative specialty chemicals for sale to third-party customers. As a result of the Performance Chemicals' repositioning, we are selling excess CTO volumes, which is outside of the ordinary course of business, that is, not a normal ongoing part of our operations and not core to our business. The excess CTO volumes, calculated as the volume directly attributable to reduced CTO refining capacity as defined under the contractual terms of the CTO supply contract, on hand at period end will be valued at the lower of cost or expected selling price, less costs to sell. Volumes on hand at period end and any pending CTO resale receivables will be recorded to Other current assets on the condensed consolidated balance sheet. Any liabilities associated with the purchases of the excess CTO volumes will be recorded to Accrued expenses on the condensed consolidated balance sheet. We will recognize the net gains or losses associated with the CTO resale activities within Other (income) expenses, net on the condensed consolidated statement of operations. Since these CTO resale activities are directly attributable to the Performance Chemicals' repositioning, that is, they do not represent normal, recurring expenses necessary to operate our business, we have excluded the CTO resale (income) charges for the purposes of calculating our non-GAAP financial performance measures.

(7) We exclude gains and losses from sales of strategic investments from our segment results, as well as our non-GAAP financial measures, because we do not consider such gains or losses to be directly associated with the operational performance of the segment. We believe that the inclusion of such gains or losses, would impair the factors and trends affecting the historical financial performance of our reportable segments. We continue to include undistributed earnings or loss, distributions, amortization or accretion of basis differences, and other-than-temporary impairments for equity method investments that we believe are directly attributable to the operational performance of such investments, in our reportable segment results.

(8) Income tax impact of non-GAAP adjustments is the summation of the calculated income tax charge related to each pre-tax non-GAAP adjustment. The non-GAAP adjustments relate primarily to adjustments in the United States. As such, the income tax effect is calculated using the statutory tax rates of 21% for the United States and approximately 2.5% for state and local taxes, applied to the non-GAAP adjustments.

(9) Represents certain discrete tax items such as excess tax benefits on stock compensation and impacts of legislative tax rate changes. Management believes excluding these discrete tax items assists investors, potential investors, securities analysts, and others in understanding the tax provision and the effective tax rate related to continuing operating results thereby providing useful supplemental information about operational performance.

(10) The weighted average number of shares outstanding used in diluted adjusted earnings per share computation (Non-GAAP) for the twelve months ended December 31, 2023 includes 0.2 million diluted shares. This number of shares differs from the weighted average number of shares outstanding used in diluted loss per share computations (GAAP) as we had a net loss for the twelve months ended December 31, 2023.

(1) Includes $0.2 million of Restricted Cash related to the new market tax credit financing arrangement.

(2) Our restricted investment is a trust managed in order to secure repayment of the finance lease obligation associated with Performance Materials' Wickliffe, Kentucky, manufacturing site at maturity. The trust, presented as Restricted investment on our condensed consolidated balance sheets, originally purchased long-term bonds that mature through 2026. The principal received at maturity of the bonds, along with interest income that is reinvested in the trust, are expected to be equal to or more than the $80.0 million finance lease obligation that is due in 2027. The restricted investment balance excludes $0.2 million allowance for credit losses on held-to-maturity debt securities within the trust.
