S T H G I L H G I H L A I C N A N I F A message from the CEO. Dear Shareholders, In many respects, 2017 was a remarkable year for Ingevity. After having successfully spun off into an independent, publicly-traded company in 2016, we focused on articulating our purpose as an organization; executed our business plans and strategies superbly; orchestrated a significant turnaround in our Performance Chemicals segment; maintained strong growth in our Performance Materials segment; leveraged the new, lower cost structure we created in 2016; announced our first acquisition; and delivered outstanding financial results. More importantly than all of this, 2017 was a record year for Ingevity’s safety performance. Our total personal and process safety incidents were an all-time low, and all but one of our manufacturing facilities completed the year without any personal injuries. Our process safety record improved as well. We completed our fourth consecutive year with zero Tier 1 process safety incidents and reduced Tier 2 process safety incidents by 80 percent. Early in the year, we introduced The IngeviWay which outlines who we are, our aspirations for the future, and the values we hold dear. It serves as a blueprint that will enable us to fulfill our purpose and realize our vision. At Ingevity, our purpose is to purify, protect and enhance the world around us. Through a team of talented and experienced people, Ingevity develops, manufactures and brings to market products and processes that help customers solve complex problems in industrial, oilfield, pavement and carbon technologies. Our innovations enable oil to flow better. They help crops grow fuller. They make roads last longer. And they ensure that the air we all breathe is cleaner. In addition, our employees embrace this calling and The IngeviWay has become the cornerstone for our work toward enhancing our unique culture and driving employee engagement. In late 2015, our Performance Chemicals segment began to face market conditions that were more difficult than anticipated. In 2016, we took some difficult steps to “right-size” our business; and in 2017, the team was able to bring to fruition a significant reversal in the momentum of the business. Our Performance Chemicals team executed their strategy, held the line on costs, and is now turning in stronger financial results with the aid of abating headwinds in the market. Our pavement technologies team continued to drive adoption of our innovative Evotherm warm mix asphalt products in the U.S.; our oilfield team developed new products and technologies to help customers in a demanding application; and in industrial specialties, we continued to battle against competitive pressures impacting prices and volumes by winning profitable, new business in several niche applications. Our Performance Materials segment continued to grow rapidly as sales of our activated carbon products accelerated due primarily to increasingly stringent regulations for automotive gasoline vapor emissions control. Despite softening light vehicle production in the U.S., our business grew largely on sales of our “honeycomb” scrubbers used by the automotive industry to comply with U. S. Environmental Protection Agency (EPA) Tier 3 and California LEV III standards. The business continues to take the steps necessary to meet rapidly growing demand, provide outstanding technical support and advocacy for our customers, and to adeptly prepare to meet increased global demand. In addition, the team has focused on the business at hand and their efforts have resulted in EBITDA margins of about 40 percent or more each quarter of the year. Aiding our financial performance in 2017 was the benefit we received from a lower cost structure built through a set of strategic initiatives implemented the prior year. What’s more, we realized tailwinds from deflated costs for our key raw material, crude tall oil. Our contracted position for CTO is expected to continue to benefit us into 2018. In August, we announced our proposed acquisition of the pine chemicals business of Georgia-Pacific. Our businesses are very complementary despite relatively low customer overlap. In combination, we will have a stronger, more competitive Performance Chemicals segment which will provide a stronger platform from which we will accelerate profitable growth. We expect the acquisition to be accretive to earnings in the first year and to derive approximately $11 million in net synergies. As a result of all of our efforts, for the full year, net sales were $972.4 million, up 7.1 percent versus the prior year. Adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) of $242.7 million were up 19.9 percent versus 2016. And, Ingevity’s 2017 adjusted EBITDA margin of 25.0 percent was up 270 basis points from the prior year’s adjusted EBITDA margin of 22.3 percent. To a degree, these numbers speak for themselves. We’re proud of our performance for the year. That said, I remain convinced that even stronger growth lies ahead of us. As we continue to work to fulfill our vision of purifying, protecting and enhancing the world around us, we are focused on enhancing our position as a leading specialty chemicals and materials company and executing our growth strategies. We believe that in so doing we are well-positioned to reward shareholders now and into the future. Best regards, D.

Business General PART I Ingevity’s business originated as part of the operations of its initial parent company, Westvaco Corporation, a paper and packaging company, using co-products of the kraft pulping process, primarily crude tall oil ("CTO") and lignin, as well as hardwood sawdust. Ingevity has operated as a division of Westvaco Corporation and its corporate successors, including MeadWestvaco Corporation and WestRock Company, since 1964. On May 15, 2016, we completed the separation of Ingevity from WestRock Company (“WestRock”) (herein referred to as the "Separation"). The Separation was completed by way of a distribution of all of the then outstanding shares of common stock of Ingevity through a dividend in kind of Ingevity's common stock (par value $0.01) to holders of record of WestRock common stock (par value $0.01) as of the close of business on May 4, 2016 (the "Record Date"). Ingevity's common stock began "regular- way" trading on the New York Stock Exchange ("NYSE") on May 16, 2016 under the symbol "NGVT." Ingevity Corporation was incorporated in Delaware on March 27, 2015. The address of Ingevity’s principal executive offices is 5255 Virginia Avenue, North Charleston, South Carolina 29406. Ingevity maintains a website at www.ingevity.com. Ingevity’s website and the information contained in or connected to the website will not be deemed to be incorporated in this document.

Ingevity Ingevity is a leading global manufacturer of specialty chemicals and high performance activated carbon materials. We provide innovative solutions to meet our customers’ unique and demanding requirements through proprietary formulated products. We report in two business segments: Performance Materials and Performance Chemicals. Our Performance Materials segment consists of our automotive technologies and process purifications product families. Automotive technologies produces automotive carbon products used in gasoline vapor emission control systems in cars, trucks, motorcycles and boats. Process purifications produces a number of activated carbon products for food, water, beverage and chemical purification applications. Our Performance Chemicals segment primarily addresses applications in three product families: pavement technologies, oilfield technologies and industrial specialties. Ingevity’s Performance Chemical products serve as critical inputs used in a variety of high performance applications, including asphalt paving, oil exploration and production, printing inks, adhesives, agrochemicals, and lubricants. Our global engineering, technical, sales and application support teams closely collaborate with our customers, and, importantly, with their customers. With our deep technical expertise and experience in our customers’ applications and end markets, we have the capacity and flexibility to anticipate and respond to changing market conditions and customer demands and to develop proactive solutions that provide our customers, and therefore us, with a distinct competitive advantage. Additionally, the quality and diversity of our product portfolio, and the flexibility of our manufacturing assets, gives us the capability to direct our resources towards their most profitable and attractive uses and geographies in response to changing market conditions. The chart below illustrates our revenue by segment, product family and sales by geography in 2017. For more information about our U.S. and foreign operations, see Note 19 of Notes to the Consolidated Financial Statements. 3 Index Product Families Primary End Uses Performance Materials Performance Chemicals Carbon Technologies Pavement Technologies Oilfield Technologies Industrial Specialties Automotive gasoline vapor emissions control Process purification Pavement preservation Well service additives Adhesives Adhesion promotion Warm mix asphalt technology Production and downstream chemicals Agrochemicals Lubricants Publication inks Industrial intermediates Revenue $349.3 million $623.1 million Sales are assigned to geographic areas based on location to which product was shipped to a third party. Our Core Strengths Ingevity is committed to continued value creation by focusing on its core strengths: Leading Global Market Positions We are a leader in the global pine chemicals industry, further distinguished by our focus on target markets that offer the potential for profitable growth, supported by long-term secular growth trends such as infrastructure preservation and development, innovation in unconventional oil exploration and production, and increasing global food production demands. Our products serve as critical inputs used in a variety of high performance applications, including asphalt paving, oil exploration and production, printing inks, adhesives, agrochemicals, and lubricants. The quality and diversity of our product portfolio, and the flexibility of our manufacturing assets, gives us the capability to direct our differentiated products towards their most profitable and attractive uses and geographies. Ingevity is the leading global manufacturer of activated carbon used in gasoline vapor emission control systems in cars, trucks, motorcycles and boats. This business is expected to benefit from increasingly stringent vehicle emission standards worldwide that our products are designed and qualified to meet. The annual global sales of light duty vehicles (i.e., passenger and light 4 Index commercial vehicles) that are powered with gasoline are forecast to grow from approximately 74 million to approximately 90 million vehicles, an increase of 22% from 2016 to 2026. Most of this growth is expected to occur outside of the United States and Canada in countries and regions where gasoline vapor emission standards significantly lag the modern, highly effective standards of the United States and Canada. This provides significant upside potential in addition to the already favorable macroeconomic growth trends of the global automotive industry. Flexible Manufacturing Capabilities Optimize Asset Utilization The quality and diversity of our product portfolio, and the flexibility of our manufacturing assets, gives us the capability to direct our resources to their most profitable uses and geographies. Our Performance Materials assets, which primarily produce automotive grade carbon, are also capable of producing a number of other activated carbon products for food, water, beverage and chemical purification applications, maximizing the productivity of these assets. Our Performance Chemical assets include multipurpose chemical reactors that are capable of manufacturing products of varying chemistries that can serve multiple markets. For example, in our South Carolina facility, the newest reactor that was commissioned in 2015 is capable of producing products for pavement, oilfield and adhesives applications, while our Louisiana assets can be redirected with relative ease among various applications including inks, adhesives, oilfield, and asphalt. Deep Technical Expertise and Product Innovation Capability and Experience We have deep technical expertise and market knowledge and insights, derived from customer relationships and research and development capabilities, that enable our ability to innovate. Innovation efforts are led and supported by our teams of technical experts and industry veterans, many of whom are considered the foremost experts in their fields, spread throughout our organization in key positions from product development to manufacturing to sales. Each of our business units has its own development and application laboratories that work in partnership with our customers to refine existing products and develop new innovative products that will drive value for Ingevity and our customers. With our technical expertise and product innovation capability and experience, and by working closely with our customers, our technical experts offer application solutions that address our customers’ most difficult challenges. For example, when our road contractor customers vary the aggregate and/or asphalt to be used in a particular job mix, they call on our expertise to quickly reformulate the Ingevity additive chemistry needed for the revised mix, so that they can meet the original job specifications on time, regardless of the change. Our ability to swiftly understand and address our customers’ performance needs allows Ingevity to maintain and grow its partnerships with its customer base. Unique Decades-Long Track Record of Automotive Carbon Products Meeting Emission Compliance Standards Current U.S. Federal and California regulatory standards and the China 6 national standard, promulgated in December 2016, require that gasoline vapor control devices remain effective for the entire life of the vehicles on which they are installed. Ingevity has a substantial, decades-long track record of providing life-of-vehicle product performance in a properly designed gasoline vapor control system. Our capability to engineer very specific mesoporous carbons on a large commercial scale allows the system designers to minimize the system’s size based on our carbon’s ability to remain highly effective over a vehicle’s lifetime. Given the imperative for automotive manufacturers to produce vehicles capable of meeting these long-term requirements, or potentially face expensive recalls and unfavorable publicity, there is an increased risk to use the products of other producers who do not have a comparable, proven history and technical capability, particularly given the significant costs associated with non- compliance should a competitor’s product fail to maintain its effectiveness over vehicle lifetimes. Global Manufacturing and Supply Chain Reach We have a global reach that allows us to effectively service multinational customers through a combination of our manufacturing facilities located in the United States and China and local talent strategically placed around the globe. In addition, our technology centers located in the United States, China, Europe and India give us the ability to service our customers throughout these regions, and provide us with market insights that allow us to develop customized solutions for local and regional markets. Our global engineering, technical, sales and application support teams serve customers in approximately 70 countries. This capability also allows us to take advantage of future market trends. For example, our oilfield technology business has in the past been primarily focused on the North American market. Our global reach allows us to pursue growth opportunities in oil and gas producing regions outside of the United States, particularly in the Middle East. 5 Index Collaborative Customer and End User Relationships Drive Profitable Growth Opportunities We take a partnership approach with our customers, investing resources to deeply understand their customers’ needs so that we can provide technologically advanced, tailored solutions that allow our customers to maintain a competitive advantage in the markets they serve. Our knowledge of our customers’ end markets provides us with insights that enable us to develop solutions that address opportunities or challenges and create value for our customers. For example, through our relationships with several automobile Original Equipment Manufacturers, or "OEMs" (often, our customers’ customer), we learned that certain vehicles were having trouble passing emissions certification tests based on a small amount of volatile organic compounds ("VOCs") migrating from the engine via the vehicles’ air intake systems. To address this issue, we developed several generations of activated carbon- based solutions, including activated carbon honeycombs and engineered activated carbon sheets, that manage these emissions while minimizing pressure drop in the air intake system-a key performance advantage to the OEMs. This drove demand for our product by addressing the needs of our customers’ customer. We believe this approach-driving demand for our products by developing solutions for our customers’ end markets-has been and will continue to be a significant driver of profitable growth. Education of Government and Regulatory Bodies on Scientifically Based Policies and Specifications Many of our customers are subject to increasing regulatory standards and mandates. For example, more stringent air quality standards drive reductions in automotive emissions or the use of recycled materials in the case of pavement technologies. With our technical expertise and experience, our teams are a valued resource and work directly with government and regulatory bodies, in support of our customers, as experts in their field to educate regulators about existing and innovative technologies that support their objectives or solve specific challenges. As the trend continues in mature and emerging markets towards more advanced solutions, we believe the ability to leverage our expertise to educate, advocate and promote sensible regulatory solutions will benefit our customers while driving incremental value within those markets. For example, Ingevity has globally recognized expertise in the highly specialized field of automotive gasoline vapor emissions. While tailpipe emissions on vehicles are well recognized, understood and regulated, gasoline vapor emissions from vehicles have been lightly regulated in many countries outside the United States and Canada. Our experts have educated authorities in other countries to help them understand and quantify the magnitude of these emissions and evaluate the highly effective solutions currently in use in the United States and Canada that can reduce these gasoline vapor emissions to “near zero” levels at a relatively low cost per vehicle. Our engagement with regulators allows us to then work with our customers in order to help them respond and adapt to evolving and varying regulatory standards. For example, because of the stringent and differing regulatory compliance standards applicable to the global oilfield industry, our oilfield customers often turn to us over smaller, less sophisticated vendors in order to help them manage the complexities of compliance risk in chemical distribution and use throughout the world. Highly Engaged, Performance and Safety-Driven Culture We have assembled a highly talented, collaborative, committed and creative team which drives the success of our business. We believe in empowerment and accountability and encourage our employees to think boldly. Our collective ambition is keenly focused on creating value for today and tomorrow. Further, we are committed to protecting human health and the environment while using resources in a responsible and sustainable manner: as a long-standing member of the American Chemistry Council ("ACC"), we subscribe to the Guiding Principles of the Responsible Care program-a global chemical industry performance initiative that is implemented in the United States through the ACC. Our ISO 9001, IATF 16949 and Responsible Care Certifications are internationally recognized measures of consistent superior performance and responsibility to health, safety, security and the environment. Long-term Secured Raw Material Supply At the time of the Separation, we entered into a long-term supply agreement with WestRock pursuant to which we purchase all of the CTO output from WestRock’s existing (at the time of separation) kraft mills, subject to certain exceptions. This relationship with WestRock is strategically important to our Performance Chemicals business due to the limited supply of CTO globally, of which we believe a significant portion is already under long-term supply agreements with other consumers of CTO. We believe this incremental supply, under this long-term supply agreement with WestRock, in conjunction with other contracted sources of CTO, will allow us to serve expected customer demand. 6 Index Our Plans for Additional Growth We have a demonstrated history of profitable growth. Looking ahead, we believe we will continue our growth while maintaining our profitability by taking the following steps: Expand Sales to Existing Customers and into New Geographies We believe we are well positioned to organically expand our sales through a combination of continued global sales growth, leveraging our significant application knowledge to apply our existing products to new applications and capitalizing on the investments we have made in our global manufacturing sales, technical centers and distribution network. Our global reach allows us to effectively compete in new geographies, delivering proven innovative solutions where opportunities to apply our technologies exist. We continue to leverage our significant application knowledge and intimate customer relationships to target opportunities where we know our products perform and to create demand for our products by driving value for our customers. We intend to continue to strengthen our position in emerging markets where we believe there are significant opportunities for growth. Opportunities include the expansion of sales of our pavement products into areas increasingly in need of newly paved roads and increased sales of activated carbon solutions driven by anticipated regulatory changes in global automotive vapor emissions control standards. Increase Our Offering of Specialized, Higher Margin Products We employ a world-class team of engineering, technical, sales and application specialists, along with experienced industry professionals, which provide us with deep technical knowledge and the ability to be a leading provider of specialty products in the markets we serve. We have the experience and capability to further develop and expand upon the products we currently produce, further differentiating them into higher value, increasingly specialized products, or developing new applications and end uses. We have a history of success in product development and differentiation. For example, our oilfield technologies business transitioned from providing basic tall oil fatty acid ("TOFA") to our customers to the development and marketing of specialized TOFA emulsifiers and corrosion inhibitors. We also grew our pavement technologies from asphalt chemicals into specialized additives used in ultra-thin paving technologies. We believe that there is significant upside in further developing and expanding upon products produced from TOFA, displacing some of our lower margin business where we sell TOFA directly to certain customers. This will have the added benefit of improved insulation from the cyclical nature of the direct natural fats and oils market of which TOFA is a part. Over the next few years, our goal is to increase the portion of our sales of specialized, higher value products derived from TOFA, including addressing new markets or opportunities to upgrade TOFA into product categories where we might not participate today. Additionally, we search to supply the right chemistry for the applications within our market segments regardless of the raw materials required. Applying our unique insights into the end use applications of our products, our team searches to find novel solutions, outside of our current CTO-based materials, to problems and our team also works to create the supply chain needed to provide those products to our customers. As an example, we have developed and now manufacture and sell product solutions in our pavement technologies business that are TOFA and hydrocarbon based. Innovate to Enable Our Customers to Adapt to Increasingly Stringent Regulatory Standards We are a valued resource with government and regulatory agencies around the world, from California to China, including national, regional and local environmental regulatory bodies. We work directly with such bodies, in support of our customers, to help them develop sensible standards based on the availability of technological solutions that make such standards commercially achievable. As standards are adopted and become increasingly demanding, the products that can be used to achieve compliance with such standards become increasingly technologically complex to design and manufacture on a commercial level. Our ability to meet these complexities provides Ingevity with a distinctive commercial edge-as our customers in many applications depend on us to help them meet their compliance standards. We also work closely with automotive companies and their suppliers to ensure that they understand and can meet increasingly stringent vehicle emission standards. Invest Organically and Selectively Pursue Acquisitions that Further Strengthen Our Product Portfolio We plan to continue to invest capital organically in attractive cost reduction projects and in capacity expansions as necessary to meet demand growth. For example, in 2016, to meet the growing demand for our activated honeycomb products that 7 Index help meet the U.S. and Canadian Low Emission Vehicle, or LEV III, and Tier 3 regulations, we began a capital expansion at our Purification Cellutions, LLC, Waynesboro, Georgia honeycomb extrusion joint venture facility that effectively doubled the capacity output by year end 2017. To support future demand for the China 6 regulation, we will be expanding activated carbon pellet extrusion capacity in Changshu, China and expect the capacity to come online in late 2018. In 2018, we also expect to commence a brownfield expansion at our Covington, Virginia activated carbon facility in order meet the growing demand for the China 6 regulation. As demand for these products grows, we will continue to evaluate additional capacity expansion as needed. In addition, we intend to pursue value-creating acquisitions, such as the acquisition of Georgia Pacific's Pine Chemicals business acquisition (which is described under “Pending Georgia Pacific's Pine Chemical Business Acquisition”), that represent attractive opportunities in our target markets as well as in high-value niche applications that complement our current product portfolio and capabilities. We continue to seek to add product lines and portfolios, as well as marketing and manufacturing alliances, that will play an important role in strengthening our leadership positions. We are evaluating acquisitions both domestically and globally. Segments Performance Materials We engineer, manufacture and sell wood-based, chemically activated carbon products, produced through a highly technical and specialized process primarily for use in gasoline vapor emission control systems in cars, trucks, motorcycles and boats. We are a global leader in automotive applications. In 2017, our Performance Materials segment generated net sales of $349.3 million and segment operating profit of $122.0 million. We also produce a number of other activated carbon products for food, water, beverage and chemical purification applications, to maximize the productivity of our manufacturing assets. Our automotive carbon products capture gasoline vapor emissions that would otherwise be released into the atmosphere as VOCs, which contain hazardous air pollutants and can photochemically react to form ozone and secondary organic aerosols. These gasoline vapor emissions (which are distinct from tailpipe emissions) are released primarily (i) during refueling, (ii) when a vehicle is parked during the daytime, as a result of evaporation and expansion of vapors in the fuel tank in warmer daytime temperatures and (iii) as “running loss,” as a result of evaporation and expansion of vapors in the fuel tank from increased temperatures as a result of operation of the vehicle. Our automotive carbon products are typically part of vehicle based gasoline vapor emissions control systems which can range from systems equipped with an approximately one liter carbon canister that captures one day of diurnal parking emissions, to more sophisticated Onboard Refueling Vapor Recovery (“ORVR”), running loss and multi-day diurnal parking systems with a two to three-liter carbon canister that is over 98% efficient. The captured gasoline vapors are largely purged from the carbon and directed to the engine where they are used as supplemental power for the vehicle. In this way, our automotive carbon products are part of a system that provides for both environmental control and energy recovery. We estimate that our products collectively prevented over 20,000 metric tons of VOC emissions each day from being lost to the atmosphere and returned the equivalent of 8 million gallons of gasoline each day to supplementary power vehicles. Environmental standards drive the implementation of gasoline vapor emission control systems by automotive manufacturers. While tailpipe emissions on vehicles are well recognized, understood and regulated, gasoline vapor emissions from vehicles have been lightly regulated in many countries outside the United States and Canada. For those countries that have not significantly regulated gasoline vapor emissions, enacting more stringent regulations represents a low-cost, high-return opportunity to address their air quality issues. The annual global sales of light duty vehicles (i.e., passenger and light commercial vehicles) that are powered with gasoline are forecast to grow from approximately 74 million to approximately 90 million vehicles, an increase of 22% from 2016 to 2026. Most of this growth is expected to occur outside of the United States and Canada in countries and regions where gasoline vapor emission standards significantly lag the modern, highly effective standards of the United States and Canada. Adoption of modern gasoline vapor emission standards in these regions would have significant, positive environmental and energy efficiency impacts and provide significant upside growth potential for our automotive carbon business. The United States and Canada have led the world in recognizing and addressing the harm to air quality caused by gasoline vapor emissions, and in early 2014 enacted regulatory standards that will further reduce these emissions to “near zero” levels by phasing in Tier 3 and LEV III evaporative emission standards through 2022, which will result in significant increases in the use of our “canister bleed emissions” system patent over that same period. The Tier 3 and LEV III phase in schedule requires compliance with the standard as follows: 40% of model year 2017’s vehicles, 60% of model year 2018’s vehicles, 80% of model year 2020’s 8 Index vehicles and 100% of model year 2022’s vehicles. The most commonly applied embodiment of the patent uses our activated carbon in the main part of the canister and our activated carbon honeycomb(s) as a “scrubber” on the outlet side of the canister to reduce the canister’s emissions to “near zero.” One of our significant “canister bleed emissions” patents expires in April 2022. The honeycombs are manufactured through an activated carbon ceramic extrusion process at our joint venture facility, Purification Cellutions, LLC, located in Waynesboro, Georgia. We have a 70 percent controlling ownership and operating responsibility in this JV and the JV is included in our consolidated results. The other 30 percent interest is owned by a U.S. based third party and the partner’s income is represented in our noncontrolling interest elimination. Most countries outside the United States and Canada have significantly lagged in the adoption of regulatory standards that would reduce these gasoline vapor emissions, focusing instead on regulating the more “visible” tailpipe emissions. These countries are using a gasoline vapor emission standard that is functionally equivalent to a 1981 U.S. regulatory standard. As a result, in Europe, Asia and Latin America, gasoline vapor emissions are the primary source of automotive VOC emissions. China recently promulgated a new national standard, China 6, that is functionally equivalent to the 2009 alignment of U.S. Tier 2 with California LEV II. This new national standard, containing ORVR and multi-day diurnal parking emission controls, is scheduled to be fully phased in by July 2020 with the potential for earlier implementation in several large municipal regions. As recognized experts in the field of gasoline vapor emission control, Ingevity has been working with regulatory bodies and relevant third parties in China, Japan, Mexico, and the European Union to help them understand and move towards more effective regulatory standards similar to those in place in the United States and Canada. Regulatory indications of adoption and implementation of more stringent vapor emissions standards outside of the United States and Canada include the following: • The European Commission has adopted more stringent gasoline vapor emission regulations with its Euro 6c standard, which will begin implementation in September 2019. This new standard is more stringent than the current standards and includes a 2-day diurnal parking emission test that will generally result in a 30 - 70% increase in canister capacities and a shift in some volumes to pellets and higher activity carbon. • On December 23, 2016, the China Ministry of Environmental Protection and the China State Administration of Quality Supervision, Inspection, and Quarantine released its China 6 National Standard on the Limits and Measurement Methods for Emissions from Light-Duty Vehicles (GB 18352 6-2016). In the new standard, diurnal control is increased to 48 hours, running loss conditions are simulated, and ORVR is added. Emissions limits are also reduced and will be similar to those in U.S. Tier 2. As a result, canister volumes are expected to increase by 2 to 3 times and the majority of the canisters are expected to shift to high activity carbons and pellets. This new standard implements nationally on July 1, 2020 but Hebei Province has announced a January 1, 2019 early implementation. • South Korea is currently phasing in some U.S. Tier 2 diurnal parking emission standards, which generally require activated carbon canister volumes greater than 1.3 liters and an increased use of pelletized carbon. In 2018, South Korea will begin phasing in portions of the U.S. Tier 3 “near zero” full vehicle diurnal parking emission standards that will favor the use of low emission and air induction system diurnal parking emission activated carbon technologies. See also “Risk Factors-Risks Related to Ingevity’s Business-Adverse conditions in the automotive market may adversely affect demand for our automotive carbon products” and “Risk Factors-Risks Related to Ingevity’s Business-If increasingly more stringent air quality standards worldwide are not adopted, our growth could be impacted.” Current regulatory standards in the United States and Canada require that gasoline vapor control devices remain effective for the entire life of the vehicles on which installed. The end of lifetime requirements for most vehicles is 10 years or 120,000 miles, but will increase to 15 years or 150,000 miles for a large segment of these U.S. vehicles. China 6 standards also include a lifetime requirement of 12 years or 160,000 kilometers. Ingevity has a substantial, decades long track record of providing life-of- vehicle product performance based on our unique capability to engineer a very specific mesoporous carbon on a large commercial scale. Given the imperative for automotive manufactures to produce vehicles capable of meeting these long term requirements, or potentially face expensive recalls and unfavorable publicity, there is an increased risk to using other producers who do not have a comparable, proven history, particularly given the significant costs associated with non-compliance should a competitor’s offering fail to maintain effectiveness over vehicle lifetimes. Additionally, because these gasoline vapor control systems are certified as “environmental devices” for models currently in production, it is time consuming and costly to replace our products within the 9 Index vehicle’s control system with a competitive product during the vehicle’s model/ platform production life due to the high cost of recertification. As a result of decades of innovation and production, Ingevity is able to produce products that are effective in smaller amounts than competitors’ offerings, meaning less product is required-which results in savings through the use of a smaller and less costly canister in the overall emissions control system. Continued innovation and manufacturing know-how should allow this advantage to continue even as competitors improve their product offerings. Ingevity is further uniquely positioned to capitalize on the opportunity afforded by the adoption of these modern vapor emission regulatory standards, which will, as a practical matter (given current technology), require manufacturers of light duty vehicles in countries adopting these standards to incrementally install advanced gasoline vapor control technology with carbon capable of meeting the new regulatory standards. Based on the regulatory trends and expected growth in vehicles, Ingevity management estimates that the revenue for its automotive emissions products could double within five to seven years from 2015. Ingevity, through its proprietary technology, trade secrets and confidential manufacturing know-how, has unparalleled capability and expertise to manufacture the high performance activated carbon products required to meet these regulatory standards, as well as more stringent standards likely to be imposed in the years to come. These same capabilities and expertise will help Ingevity to maintain its position in the United States and Canada automotive markets as they advance their standard to “near zero” gasoline vapor emission levels. We also produce a number of other activated carbon products for food, water, beverage and chemical purification applications to maximize the productivity of our manufacturing assets. Additionally, as automotive engine technology continues to evolve and engines become more efficient, the amount of airflow available in the fuel system to purge the gas vapor from the activated carbon products is expected to decline (“low-purge”). We believe that the pore structure characteristics of our activated carbon products additionally advantages us versus competitors’ offerings in low purge conditions. Ingevity is actively investing in product and process development that is designed to deal with low-purge engines. For further information on measures of profitability used by managers of the business and its segments, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Raw Materials and Production 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 consume phosphoric acid, which is used 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. In the recent past, there have been price run-ups in phosphoric acid due to increased phosphate rock demands in global agriculture, which have in turn negatively affected our business. Activated carbon is an amorphous form of carbon characterized by a high volume of nanoscale pores. “Activation” refers to the process of developing these pores. The size, shape and volume of the pore structure and the surface chemistry of the pore are critical for driving performance in various applications. Activated carbons are typically produced from either a thermal or chemical process utilizing a wide variety of carbonaceous raw materials. The thermal process, the most widely used activation process, uses rotary kilns or multi-hearth furnaces to carbonize and activate the raw material. This process operates at a much higher temperature and at a lower yield than the chemical activation process. Typical raw materials include bituminous coal, lignite and coconut husks. Thermally activated carbons are usually used for “catch and dispose” applications, whereby the carbon is used to capture certain compounds and the carbon product is then disposed of or thermally regenerated. 10 Index Ingevity employs a more specialized activation process, whereby chemical catalysts (most often phosphoric acid or zinc chloride) and various heating methods are used to facilitate the development of porosity. This process operates at a lower temperature and typically has higher yields than a thermal process. Carbons produced by this method typically have larger pores than thermally activated carbons and can be used in both “catch and dispose” applications and “catch and release” applications, whereby the carbon is used to capture and temporarily hold on to certain compounds which are then released in a controlled manner under specific operating conditions. We use hardwood sawdust to produce chemically activated carbon, which, because of its higher pore volume, pore structure and high surface area, is well-matched for a variety of applications and ideally suited for the “catch and release” automotive application of capturing and reusing gasoline vapor emissions. We further process activated carbon after it is activated into different forms using a variety of extrusion processes. One of our extrusion processes is to use activated carbon and various binders to make a formed pellet. Pelleted carbon is typically used in canister applications where a low pressure drop system is required such as ORVR. Another extrusion process we employ is with our honeycomb “scrubber.” We utilize an activated carbon infused ceramic extrusion process. These honeycomb “scrubbers” are used with the Company’s patented system to reduce the canister’s emissions to “near zero” and are manufactured at our joint venture facility, Purification Cellutions, LLC, located in Waynesboro, Georgia. Customers We sell our automotive products to over 60 customers around the globe. In 2017, our ten largest customers accounted for 79% of the segment's sales. We are the trusted source of these products for many of the world’s largest automotive parts manufacturers, including Aisan Industry, Delphi Automotive, MAHLE, and many other large and small component manufacturers throughout the global supply chain. Our relationship with many of our customers and their customers-the vehicle manufacturers themselves-have been in place for most of our history in this application. Ingevity also produces activated carbon products for food, water, beverage and chemical purification applications, which are sold to over 90 customers throughout the world. We operate primarily through a direct sales force in North America and our other major markets and also have a smaller, focused network of agents and distributors that have established a strong direct sales and marketing presence. Competition In automotive carbon, Ingevity has a unique decades-long track record of providing life-of-vehicle performance. Given the imperative for automotive manufacturers to produce vehicles for the United States and Canadian markets capable of meeting life-of-vehicle emission standards, or potentially face expensive recalls and unfavorable publicity, our automotive carbon products provide our customers the low-risk choice in this high performance application. Our competitors in automotive carbon include Cabot Corp., Kuraray, and several Chinese manufacturers. Our process purification business competes mainly in the United States in the food, beverage, chemical and water purification applications. Competitors in our process purification product line include Cabot Corp., Calgon Carbon, Jacobi Carbons and several domestic U.S. manufacturers and distributors of imported products. Refer to Item 1A - "Risk Factors-We face competition from producers of alternative products and new technologies." Performance Chemicals Ingevity’s Performance Chemicals segment, which is comprised of three application areas (pavement technologies, oilfield technologies and industrial specialties), develops, manufactures and sells a wide range of specialty chemicals primarily derived from co-products of the kraft pulping process. Products include performance chemicals derived from pine chemicals used in asphalt paving, oilfield exploration and production, printing inks, adhesives, agrochemical dispersants, lubricants, and other diverse industrial uses. Our application expertise is often called upon to provide unique solutions to our customers that maximize resource efficiency. We have a broad and diverse customer base in this segment. In 2017, our top ten customers accounted for approximately 35% of our segment revenue; the next 100 customers made up approximately 44% of our segment revenue. For 2017, our Performance Chemicals segment had revenue and segment operating profit of $623.1 million and $80.3 million, respectively. For further information on measures of profitability used by managers of the business and its segments, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” 11 Index Raw Materials and Production Our Performance Chemicals business serves customers globally from two manufacturing locations in the United States. Most of our performance chemicals are derived from CTO, a co-product of the kraft pulping process, where pine is used as the source of the pulp. CTO is produced by acidulating black liquor soap skimmings ("BLSS"), which are recovered during the kraft pulping process. Consumers of CTO can purchase BLSS from pulping mills that do not have acidulation capacity (in which case the BLSS will need to be acidulated into CTO), and purchase CTO from pulping mills that do have acidulation capacity. The CTO is further separated by distillation into tall oil rosin ("TOR"), TOFA and other biofractions. As such products are further refined or chemically modified, higher value derivative products are created, making their way into a wide variety of industrial and consumer goods. We also produce performance chemicals derived from lignin, also a co-product of the kraft pulping process. TOR and TOFA are sold directly to customers in some instances, or, along with lignin, further refined or chemically modified into higher value derivative products. Our differentiated performance chemicals are engineered to meet specific industry standards and customer requirements. The primary raw material used in our Performance Chemicals segment is CTO. The availability of CTO is directly linked to the production output of kraft mills using pine as their source of pulp, which is the predominant fiber source for packaging grades of paper. As a result, there is a finite global supply of CTO-with global demand for kraft pulp driving the global supply of CTO, rather than demand for CTO itself. Most of the CTO made available for sale by its producers is covered by long-term supply agreements, further constraining availability. At the time of the Separation, we entered into a long-term supply agreement with WestRock pursuant to which we purchase all of the CTO output from WestRock’s existing (at the time of separation) kraft mills, subject to certain exceptions. Beginning in 2025, either party may provide a notice to the other party terminating the agreement five years from the date of such notice. Beginning one year after such notice, the quantity of products provided by WestRock under the agreement will be gradually reduced over a four-year period based on the schedule set forth in the agreement. In addition, from 2022 until 2025, either party may provide one-year notice to remove a kraft mill as a supply source. The two largest kraft mills under the agreement currently are expected to supply approximately 18% to 19% and 15% to 16%, respectively, of the total amount of products expected to be supplied under our agreement with WestRock. In the event that WestRock exercises its right to terminate our supply agreement with them or remove a kraft mill as a supply source, we may be able to obtain substitute supplies of CTO from other suppliers, spot purchases or a new contract with WestRock. The agreement with WestRock includes pricing terms based on market prices. Under this agreement, based on WestRock’s current output, we currently expect to source approximately 45% to 55% of our CTO requirements through 2025 based on the maximum operating rates of our two Performance Chemicals' facilities. We also have agreements with other suppliers to satisfy substantially all of the balance of our expected requirements of CTO through 2018. We believe that we are well positioned to have sufficient CTO required for our operations. However, if any of our suppliers (including WestRock) fail to meet their respective obligations under our supply agreements or we are otherwise unable to procure an adequate supply of CTO, we would be unable to maintain our current levels of production. In addition, if WestRock exercises its rights to terminate the agreement or remove a kraft mill as a supply source, and we are unable to arrange a substitute supply of CTO, we would be unable to maintain our current levels of production. Additionally, there are other pressures on the availability of CTO. Some kraft pulp mills may choose to consume their production of CTO to meet their energy needs rather than sell the CTO to third parties. Furthermore, 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 meeting our quality standards. See “Risk Factors- Risks Related to Ingevity’s Business-Our Performance Chemicals segment is highly dependent on CTO which is limited in supply; lack of access to sufficient CTO would impact our ability to produce CTO-based products.” Also, regulatory incentives and mandates in Europe for the use of biofuel have placed additional pressure on CTO availability. See “Risk Factors-Risks Related to Ingevity’s Business-The European Union’s Directive 2009/28 on the promotion of the use of energy from renewable resources (“Renewable Energy Directive” or “RED”) and similar legislation in the United States and elsewhere may incentivize the use of CTO as a feedstock for production of alternative fuels.” Finally, CTO as a raw material may be subject to significant pricing pressures. See “Risk Factors- Risks Related to Ingevity’s Business-Pricing for CTO is subject to particular pricing pressures by reason of limited supply and competing demands for end use, and we may be limited in our ability to pass on increased costs to our customers” and “Risk Factors-Risks Related to Ingevity’s Business-The Company’s oilfield technologies business is significantly affected by trends in oil and natural gas prices that affect the level of exploration, development and production activity.” 12 Index The other key raw materials used in the Performance Chemicals business are nonylphenol, pentaerythritol and ethylene amines. These are sourced where possible through multiple suppliers to protect against supply disruptions and to maintain competitive pricing.

In our adhesives business, our products compete against other tackifiers, including other TOR-based tackifiers as well as tackifiers produced from gum rosin and hydrocarbon starting materials. In addition, the choice of polymer used in an adhesive formulation drives the selection of tackifier. In agrochemicals, the selection of a dispersant is made early in the product development cycle and the formulator has a choice among Ingevity’s sulfonated lignin products, lower quality lignosulfonates and other surfactants such as naphthalene sulfonates. In lubricants, we compete against other producers of distilled tall oil and additives. In inks, our products compete against other resins that can be derived from TOR, gum rosin and, to a lesser extent, hydrocarbon sources. In our intermediates business, our TOFA competes against widely available fats and oils derived from soy, rapeseed, palm, cotton and tallow sources. Competitors are different depending on the product, application and region and include Kraton, Eastman Chemical, ExxonMobil, Borregaard, Lawter, Respol/Forchem, DRT, as well as several others. 14 Index Pending Georgia Pacific's Pine Chemical Business Acquisition On August 22, 2017, we entered into an Asset Purchase Agreement (the "Purchase Agreement") with Georgia-Pacific Chemicals LLC, Georgia-Pacific LLC (together with Georgia-Pacific Chemicals LLC, "GP") and Ingevity Arkansas, LLC, a wholly-owned subsidiary of Ingevity, to purchase substantially all the assets primarily used in GP's pine chemical business (the "Pine Chemical Business"), including assets and facilities related to tall oil fractionation operations and the production or modification of tall oil fatty acids, tall oil rosins, rosin derivatives and formulated products (the "Acquisition"). The purchase price for the Acquisition is $315 million, subject to a customary adjustment to reflect normalized working capital for the Pine Chemical Business. In addition to the purchase price, at the closing of the Acquisition, we will assume certain liabilities related to the Pine Chemical Business. The closing of the Acquisition is subject to regulatory clearance and other customary closing conditions, which are currently ongoing. We intend to use the net proceeds from the $300.0 million senior unsecured notes issued on January 24, 2018, to finance the Acquisition. Pursuant to the Purchase Agreement, GP has agreed to indemnify the Company for losses resulting from a breach of certain representations and warranties and excluded liabilities, subject to certain limitations. Furthermore, the Purchase Agreement contains various termination provisions available to the parties thereto. In addition, at the closing of the Acquisition, the Company and GP intend to enter into certain transition and shared services agreements to effectuate the transfer of the assets pursuant to the Acquisition. Separately, at the closing of the Acquisition, Ingevity and GP will also enter into a supply agreement, whereby certain GP paper mills will supply CTO to Ingevity at market- based prices for a term of 20 years. 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. All of our manufacturing processes also consume a significant amount of electricity. All of our facilities are located in regulated service areas that have stable rate structures with reliable electricity supply. Environment Our operations are subject to extensive regulation by federal, state and local authorities, as well as regulatory authorities with jurisdiction over the foreign operations of Ingevity, including relating to the discharge of materials into the environment and the handling, disposal and clean-up of waste materials, and otherwise relating to the protection of the environment. 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 it is anticipated that such compliance will not have a material adverse effect on any of the foregoing. For a further discussion, see “Risk Factors-Risks Related to Ingevity’s Business-Our business involves hazards associated with chemical manufacturing, storage, transportation and disposal” and “Risk Factors-Risks Related to Ingevity’s Business-The Company’s operations are subject to a wide range of general and industry specific environmental laws and regulations.” Environmental regulation and legal proceedings have the potential for involving significant costs and liability for Ingevity. Backlog In general, we do not manufacture our products against a backlog of orders and do not consider backlog to be a significant indicator of the level of future sales activity. Production and inventory levels are based on the level of incoming orders as well as projections of future demand. Therefore, we believe that backlog information is not material to understanding our overall business and should not be considered a reliable indicator of our ability to achieve any particular level of revenue or financial performance. 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. 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, other than our “canister bleed emissions” patent, which is part of our automotive business and expires in April 2022, there is no individual patent or trademark the loss of which could have a material adverse effect 15 Index on the business. The most commonly applied embodiment of the “canister bleed emissions” patent uses our activated carbon in the main part of the canister and our activated carbon honeycomb(s) from our joint venture, Purification Cellutions, LLC, facility, as a “scrubber” on the outlet side of the canister to reduce the canister’s emissions to “near zero.” 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. See “Risk Factors-Risks Related to Ingevity’s Business-If we are unable to adequately protect our intellectual property, we may lose significant competitive advantages,” and “Risk Factors-Risks Related to Ingevity’s Business- We are subject to cyber-security risks related to our intellectual property and certain other data.” Research and Technical Development We employ a world-class team of engineering and scientific professionals, many of whom hold Doctor of Philosophy ("Ph.D.") degrees and are considered some of the foremost experts in their fields, with deep knowledge of our customers’ markets. We spent $19.8 million, $17.6 million and $17.4 million for the years ended December 31, 2017, 2016 and 2015, respectively, on research and technical expense, which was expensed as incurred. Seasonality There are a variety of seasonal dynamics that impact our businesses, though none materially affect financial results, except in the case of the pavement technologies business, where roughly 74% of its revenue is generated between April and September. From a supply perspective, this seasonality is effectively managed through pre-season inventory build then active inventory management throughout the year. Employees We currently employ approximately 1,500 employees, of whom 82% are employed in the United States. Approximately 17% are represented by labor unions, domestic and international, under various collective bargaining agreements. We engage in negotiations with labor unions for new collective bargaining agreements from time to time based upon expiration dates of agreements and statutory requirements. We consider our relationships will all salaried, union hourly and non-hourly employees to be positive and collaborative. During 2017, Ingevity ratified new labor agreements with International Brotherhood of Electrical Workers (“IBEW”) and Covington Paperworkers Union at our Covington, Virginia location, and United Steel Workers (“USW”) at our Wickliffe, Kentucky location. The collective bargaining agreements with the USW, representing production and maintenance employees; the IBEW, representing instrument and electrical workers; and the International Association of Machinists and Aerospace Workers (“IAM”), representing maintenance employees at our North Charleston plant, will expire June 30, 2018. Ingevity has begun to prepare for negotiations with all three unions representing employees at the North Charleston plant in 2018. 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 our company. However, the risks and uncertainties our company faces 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 develops 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. General Business 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 the value of local currency versus the U.S. dollar or the impact 16 Index of a stronger U.S. dollar which may negatively impact our ability to compete. Macro-economic challenges, including conditions in financial and capital markets and levels of unemployment, and the ability of the United States 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. We are exposed to the risks inherent in international sales and operations. In 2017, export sales from the United States made up approximately one third of our total sales, and we sell our products to customers in approximately 70 countries. We have exposure to risks of operating in many foreign countries, including: • • • • • • • • • • • • fluctuations in foreign currency exchange rates, including the euro, Japanese yen and Chinese renminbi; restrictions on, or difficulties and costs associated with, the repatriation of cash from foreign countries to the United States; difficulties and costs associated with complying with a wide variety of complex laws, treaties and regulations; 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; political and economic instability; import and export restrictions and other trade barriers; 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. We have also expanded our participation in certain markets. As our international operations and activities expand, we inevitably have greater exposure to the risks of operating in many foreign countries. Our reported results could be adversely affected by currency exchange rates and currency devaluation could impair our competitiveness. Due to our international operations, we transact in many foreign currencies, including but not limited to the euro, Japanese yen and Chinese renminbi. As a result, we are subject to the effects of changes in foreign currency exchange rates. During times of a strengthening U.S. dollar, our reported net revenues and operating income will be reduced because the local currency will be translated into fewer U.S. dollars. During periods of local economic crisis, local currencies may be devalued significantly against the U.S. dollar, potentially reducing our margin. Ingevity may enter forward exchange contracts and other financial contracts in an attempt to mitigate the impact of currency rate fluctuations. However, there can be no assurance that such actions will eliminate any adverse impact from variation in currency rates. Also, actions to recover margins may result in lower volume and a weaker competitive position, which may have an adverse effect on our profitability. 17 Index Our operations outside the United States require us to comply with a number of U.S. and foreign regulations, violations of which could have a material adverse effect on our financial condition and results of operations. Our operations outside the United States require us to comply with a number of U.S. and international regulations. For example, our operations in countries outside the United States are subject to the United States Foreign Corrupt Practices Act (“FCPA”), which prohibits U.S. companies and their agents and employees from providing anything of value to a foreign official for the purposes of influencing any act or decision of these individuals in their official capacity to help obtain or retain business, direct business to any person or corporate entity, or obtain any unfair advantage. Our activities may create the risk of unauthorized payments or offers of payments by our employees, agents or joint venture partners that could be in violation of anti-corruption laws, even though these parties are not subject to our control. We have internal control policies and procedures and training and compliance programs for our employees and agents with respect to the FCPA. However, we cannot assure that our policies, procedures and programs always will protect us from reckless or criminal acts committed by our employees or agents. Allegations of violations of applicable anti-corruption laws may result in internal, independent or government investigations. Violations of anti-corruption laws may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could have a material adverse effect on our financial condition and results of operations. In addition, the shipment of goods, services and technology across international borders subjects us to extensive trade laws and regulations. Our import activities are governed by the unique customs laws and regulations in each of the countries where we operate. Moreover, many countries, including the United States, control the export and re-export of certain goods, services and technology and impose related export record-keeping and reporting obligations. Governments may also impose economic sanctions against certain countries, persons and entities that may restrict or prohibit transactions involving such countries, persons and entities, which may limit or prevent our conduct of business in certain jurisdictions. The laws and regulations concerning import activity, export record-keeping and reporting, export control and economic sanctions are complex and constantly changing. These laws and regulations can cause delays in shipments and unscheduled operational downtime. Moreover, any failure to comply with applicable legal and regulatory trading obligations could result in criminal and civil penalties and sanctions, such as fines, imprisonment, debarment from governmental contracts, seizure of shipments and loss of import and export privileges. In addition, investigations by governmental authorities as well as legal, social, economic and political issues in these countries could have a material adverse effect on our business, results of operations and financial condition. We are also subject to the risks that our employees, joint venture partners and agents outside of the United States may fail to comply with other applicable laws. Risks Related to Ingevity’s Business We are dependent on attracting and retaining key personnel. The Company is dependent upon its senior management, as well as upon engineering, technical, sales and application specialists, together with experienced industry professionals. Our success depends, in part, on our ability to attract, retain and motivate these key performers. Our failure to attract and retain those making significant contributions could adversely affect our financial condition and results of operations. Adverse conditions in the automotive market may adversely affect demand for our automotive carbon products. Sales of our automotive activated carbon products are tied to global automobile production levels. Automotive production in the markets we serve can be affected by macro-economic factors such as interest rates, fuel prices, consumer confidence, employment trends, regulatory and legislative oversight requirements and trade agreements. For example, the global economic downturn in 2008/2009 led to a drastic reduction in vehicle sales and an even greater reduction in vehicle production as OEMs right-sized their inventories to meet the lower sales volumes. Regional disruptions such as those caused by the Japan earthquake and resulting tsunami in March 2011 and Hurricane Sandy in October 2012 can also significantly impact vehicle production and therefore demand for our automotive carbon. In addition, growth in alternative vehicles, such as all-electric vehicles and hydrogen fuel cell vehicles, which do not use gasoline, may also adversely affect the demand for our products. If increasingly more stringent air quality standards worldwide are not adopted, our growth could be impacted. 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 18 Index gasoline vapor emissions, enacting more stringent regulations governing gasoline vapor emissions represents a significant upside to the Company’s automotive carbon business. However, regulators may react to a variety of considerations, including economic and political, that may mean that any such more stringent regulations are 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 a significant impact on the growth prospects for these products. The Company’s printing inks business serves customers in a market that is facing declining volumes. In recent years, the use of inks in which our printing ink resins are used, such as those made for magazines and catalogues, has significantly decreased, as the printing industry has experienced a reduction in demand due to various factors including the great recession of 2008 and 2009, which severely impacted volumes, and competition from alternative sources of communication, including email, the Web, electronic readers, interactive television and electronic retailing. The impacts of these changes have led to continued intense competition and downward pricing pressures on printing inks, and therefore, our ink products. The Company’s pavement technologies business is heavily dependent on government infrastructure spending. A significant portion of our customers’ revenues in our pavement technologies business is derived from contracts with various foreign and U.S. governmental agencies, and therefore, when government spending is reduced, our customers’ need 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, 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 the expenditures and delays 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. The Company’s oilfield technologies business is significantly affected by trends in oil and natural gas prices that affect the level of exploration, development and production activity. Demand for our oilfield technologies services and products is particularly sensitive to the level of exploration, development and production activity of, and the corresponding capital spending by, oil and natural gas companies, including national oil companies. The level of exploration, development and production activity is directly affected by trends in oil and natural gas prices, which historically have been volatile. Crude oil prices have declined significantly since 2014, with West Texas Intermediate oil spot prices declining from a high of $108 per barrel in June 2014 to a low of $27 per barrel in February 2016, a level which had not been experienced since 2003. Since February 2016, pricing has climbed to a trading range of $55 to $65 per barrel in the November 2017 to January 2018 time frame. Pricing is not currently forecasted to improve significantly from these levels during 2018. While these pricing levels are significantly above the February 2016 levels, they remain off their highs seen in the last decade. Any prolonged low pricing environment for oil and natural gas is likely to result in reduced demand for our oilfield technology products, which may have a material adverse effect on our results of operations. In order to compete successfully, we must develop new products and technologies meeting evolving market and customer needs; disruptive technologies could reduce the demand for the Company’s products. Our industries and the end-use markets into which we sell our products experience periodic technological change and product improvement. Our future growth will depend on our ability to gauge the direction of commercial and technological progress in key end-use markets and on our ability to fund and successfully develop, manufacture and market products in such changing end-use markets. If we fail to keep pace with the evolving technological innovations in our end-use markets on a competitive basis, including with respect to innovation with regard to the development of alternative uses for, or application of, products developed that utilize such end-use products, our financial condition and results of operations could be adversely affected. Similarly, we face competition in our applications. Disruptive technology involving new or superior solutions could reduce the demand for the Company’s products. 19 Index If we are unable to adequately protect our intellectual property, we may lose significant competitive advantages. 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 our “canister bleed emissions” patent. We will 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. 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. A failure to protect, defend or enforce our intellectual property 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. We also rely materially 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. 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. If we must take legal action to protect, defend or enforce our intellectual property rights, any suits or proceedings could result in significant costs and diversion of our resources and our management’s attention, and we may not prevail in any such suits or proceedings. A failure to protect, defend or enforce our intellectual property rights could have an adverse effect on our results of operations. Our Performance Chemicals segment is highly dependent on CTO, which is limited in supply; lack of access to sufficient CTO would impact our ability to produce CTO-based products. The availability of CTO is essential to the Company’s Performance Chemicals segment. Availability of CTO is directly linked to the production output of kraft mills using pine as their source of pulp, which is the predominant fiber source for packaging grades of paper. As a result, there is a finite global supply of CTO-with global demand for kraft board driving the global supply of CTO, rather than demand for CTO itself. Most of the CTO made available for sale by its producers in North America is covered by long-term supply agreements, further constraining availability. At the time of the Separation, we entered into a long-term supply agreement with WestRock pursuant to which we purchase all of the CTO output from WestRock’s existing (at the time of separation) kraft mills, subject to certain exceptions. This agreement includes pricing terms based on market prices. Under this agreement, based on WestRock’s current output, we currently expect to source approximately 45% to 55% of our CTO requirements based on the maximum operating rates of our two Performance Chemicals' facilities. We also have agreements with other suppliers to satisfy substantially all of the balance of our expected requirements of CTO through 2018. Pricing for the products in our agreement with WestRock is based on the prevailing market prices of products at the time of purchase. The pricing formulas are subject to certain pricing floors as set forth in the agreement. Given the take-or-pay requirements of the agreement, in adverse market conditions we could be required to purchase CTO from WestRock at prices where our results of operations could be materially and adversely affected. If any of our suppliers (including WestRock) fail to meet their respective obligations under our supply agreements or we are otherwise unable to procure an adequate supply of CTO, we would be unable to maintain our current level of production and our results of operations would be materially and adversely affected. Beginning in 2025, either party to the WestRock agreement may provide a notice to the other party terminating the agreement five years from the date of such notice. Beginning one year after such notice, the quantity of products provided by WestRock under the agreement will be gradually reduced over a four-year period based on the schedule set forth in the agreement. In addition, from 2022 until 2025, either party may provide a one-year notice to remove a kraft mill as a supply source. The two largest kraft mills under the agreement currently supply approximately 18% to 19 % and 15% to 16%, respectively, of the total amount of products supplied under our agreement with WestRock. If WestRock exercises its rights to terminate the agreement or 20 Index remove a kraft mill as a supply source, and we are unable to arrange for a substitute supply of CTO, we would be unable to continue to produce the same quantity of products and our results of operations could be materially and adversely affected. There are other pressures on the availability of CTO. Some pulp or paper mills may choose to consume their production of CTO to meet their energy needs rather than sell the CTO to third parties. Also, as described below, there are regulatory pressures that may incentivize suppliers of CTO to sell CTO into alternative fuel markets rather than to historical end users such as Ingevity. Furthermore, 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 meeting Ingevity’s quality standards. For example, the combined impact of Hurricane Katrina in August 2005 and Hurricane Rita in September 2005 caused significant damage to forests throughout the southern United States. This significantly affected the availability and quality of the supply of CTO during late 2005 and into 2006. The European Union’s Directive 2009/28 on the promotion of the use of energy from renewable resources (“Renewable Energy Directive” or “RED”) and similar legislation in the United States and elsewhere may incentivize the use of CTO as a feedstock for production of alternative fuels. In December 2008, the European Union (“EU”) adopted the Renewable Energy Directive, which established a 20% EU- wide target for energy consumed from renewable sources relative to the EU’s gross final consumption of energy, as well as a 10% target for energy consumed from renewable sources in the transport section. In order to reach these targets, the RED established mandatory targets for each Member State and required each Member State to adopt a national renewable energy action plan setting forth measures to achieve its national targets. The RED also established sustainability criteria for biofuels, which must be satisfied in order for the consumption of a fuel to count toward a Member State’s national targets. CTO-based biofuel currently satisfies the RED’s biofuel sustainability criteria. In spring 2015, the EU adopted amendments to the Renewable Energy Directive. RED now expressly lists CTO as a residue-type feedstock whose use in biofuel would make that biofuel eligible for double counting towards national targets of the Member States, and at least two Member States additionally have or plan fiscal incentives for the domestic marketing of CTO- based and other qualifying biofuels. The EU is drafting legislation for RED II, which, if adopted, will replace RED as the renewal energy policy for 2020 to 2030. In addition to these developments in the European Union, various pieces of legislation regarding the use of alternative fuels have been introduced in the U.S. Currently, none of the U.S. legislation mandates or provides incentives for the use of CTO as a transportation fuel. Some regional cap and trade programs may incentivize the use of CTO in stationary sources. Because the supply of CTO is inherently constrained by the volume of kraft pulp processing, any diversion of CTO for production of alternative fuels would reduce the available supply of CTO as the principal raw material of the pine chemicals industry. As described above, the Company is highly dependent on CTO as an essential raw material, and if the Company is unable to procure an adequate supply of CTO due to competing new uses such as for biofuel production, the Company’s results of operations would be materially and adversely affected. Pricing for CTO is subject to particular pricing pressures by reason of limited supply and competing demands for end use, and we may be limited in our ability to pass on increased costs to our customers. Pricing for CTO (which accounted for approximately 13 percent of all of our cost of sales and 35 percent of our raw materials purchases for 2017) is subject to particular pricing pressures by reason of the limited supply elasticity of the product and competing demands for its use, all of which drive pressure on price: • CTO is a product of the kraft pulping process, and the global supply of CTO is inherently constrained by the volume of kraft pulping processing; • CTO can be burned as alternative fuels, either in support of the originating pulp mill operations, by energy companies or biofuel companies; and • Regulations or other incentives to mandate or encourage the consumption of biofuels as alternatives, including CTO. We may not have the ability to pass through any increases in our cost of CTO to our customers in the form of price increases or other adjustments, with a resulting material adverse effect on our results of operations. Additionally, we may be placed at a competitive disadvantage relative to our competitors who rely on different primary raw materials or who have more favorable terms with their suppliers. 21 Index We are also dependent on other raw materials, and these are also subject to pricing pressures; lack of access to these raw materials and inability to pass on price increases could adversely affect our financial condition and results of operations. The Company is dependent on other raw materials, including, but not limited to, sawdust, phosphoric acid, ethylene amines, lignin, nonylphenol, and pentaerythritol. Raw material costs are a significant operating expense of the Company. The cost of raw materials can be volatile and subject to increases as a result of, among other things, changing economic conditions, political or policy considerations, supply and demand levels, instability in energy producing nations, and natural events such as extreme weather events or even insect infestations. Any interruption in the supply of the raw materials on which we depend, and any increases in the cost of raw materials that we are not able to pass on to customers in the form of price increases or other adjustments, may materially impact our financial condition and results of operations. A prolonged period of low energy prices may materially impact our results of operations. The price of energy may directly or indirectly impact demand, pricing or the profitability for certain Ingevity products. As petroleum oil prices fall or change rapidly, Ingevity products may be disadvantaged due to the fact that CTO and BLSS are thinly traded commodities 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 market place. Protracted periods of high volatility or sustained oversupply of petroleum oil may also translate into increased competition from petroleum-based alternatives which would otherwise be consumed in petroleum transportation fuel blends. In addition, pricing for competing naturally derived oils such as palm or soybean is likely to provide further pressure on pricing of the Company’s products during periods of depressed petroleum prices. We face competition from producers of alternative products and new technologies. In the Performance Materials segment, there is competition from various other activated carbon manufacturers. These competitors are actively trying to develop more advanced and alternative activated carbon products that would more effectively compete with our products in the automotive applications. There is also competition in the automotive applications from non- activated carbon competitors or product offerings. For example, at least one OEM is using sealed tanks in certain subsets of its vehicles to comply with the LEV III/Tier 3 regulations. While the sealed tank fuel systems generally require a similarly sized pelleted activated carbon canister to deal with refueling emissions, in most cases, they do not use a honeycomb to meet current U.S. and California regulations. If a competitor were to succeed in developing products that are better suited for automotive evaporative emissions capture applications and/or a competitive technology, such as, but not limited to, sealed gas tanks, were to be implemented across a material number of vehicle platforms, our financial results could be negatively impacted. In the Performance Chemicals segment, hydrocarbon resins and gum rosin-based products compete with TOR-based resins in the adhesives and inks markets. The price of gum rosin has a significant impact on the market price for TOR and rosin derivatives and the price of gum rosin is driven by labor rates, land leasing costs and various other factors that are not within our control. Hydrocarbon resins, for example, C5 resins, are co-products from isoprene (synthetic rubber). Availability and pricing are determined by the supply and demand for synthetic rubber as well as crude oil prices as the feedstock for isoprene and various other factors that are not within our control. Animal and vegetable-based fatty acids compete with TOFA products in lubricant and industrial specialties. The market price for TOFA products is impacted by the prices of other fats and oils and the prices for other fats and oils is driven by actual and expected harvest rates, crude oil prices and the biofuel market. Additionally, the Company faces competition from competitors that are actively developing new technologies and competing products across the segment. A significant investment by a competitor in a competitive technology or product line could negatively impact our financial results. Disruptions at any of our manufacturing facilities or within our supply chain could negatively impact our production, financial condition and results of operations. An operational disruption in any of our facilities could negatively impact production and our financial results. The occurrence of a natural disaster, such as a hurricane, tropical storm, earthquake, tornado, severe weather, flood, fire or other unanticipated problems such as labor difficulties, equipment failure, capacity expansion difficulties or unscheduled maintenance could cause operational disruptions of varied duration. These types of disruptions could materially adversely affect our financial condition and results of operations to varying degrees dependent upon the facility, the duration of the disruption, our ability to shift business to another facility or find alternative sources of materials or energy. In certain cases, we have some products that are only made at one facility. For example, in the case of our Purification Cellutions, LLC, Waynesboro, Georgia honeycomb joint venture, while we have some redundancies within the facility, we only have one facility that makes these extruded honeycomb products. As another example, we make the vast majority of our ink resin products in our DeRidder, Louisiana facility. While we 22 Index have redundancies within the facility, we have limited ability to make these products at other facilities. Any losses due to these events may not be covered by our existing insurance policies or may be subject to certain deductibles. We could be similarly adversely affected by disruptions within our supply chain and transportation network. Our products are transported by truck, rail, barge or ship 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, tariffs, rising fuel costs and capacity constraints. Significant delays or increased costs affecting these transportation methods could materially affect our financial condition and results of operations. Disruptions at our suppliers could lead to short term or longer rises in raw material or energy costs and/or reduced availability of materials or energy, potentially affecting 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 at our Covington, Virginia Performance Materials facility and at our North Charleston, South Carolina Performance Chemicals facility. We are dependent on the WestRock Covington, Virginia paper mill (“WestRock Paper Mill”) for the provision of electricity, water, compressed air, steam and wastewater treatment to our Covington Performance Materials facility and we are similarly dependent on the KapStone Paper and Packaging Corporation (“KapStone”) North Charleston, South Carolina paper mill (“KapStone Paper Mill”) for the provision of water, compressed air, steam and wastewater treatment at our North Charleston Performance Chemicals facility. We have existing long-term contractual arrangements covering these services for our Covington and North Charleston facilities. The provision of these services would be at risk if any of the counterparties were to idle or permanently shut down the associated mill, or if operations at the associated mill 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 WestRock Paper Mill or KapStone Paper Mill were to fail to provide the contracted services, we would be required to obtain these services from other third parties 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 Paper Mill wastewater treatment operations do not comply with permits or applicable law and the WestRock Paper Mill is unable to determine the cause of such compliance, then we will be responsible for between 10% and 50% of the costs and expenses of such noncompliance (increasing in 10% increments per violation during each twelve month period) despite representing less than 3% of the total wastewater volume. These costs and expenses may be significant and may adversely affect our financial condition and results of operations. Additionally, our Covington Performance Materials facility is located on real property leased from WestRock pursuant to a long-term lease agreement, and is surrounded by the WestRock Paper Mill, and a portion of our North Charleston Performance Chemicals facility is located on real property leased from KapStone and is adjacent to the KapStone Paper Mill. In the event we were to have a dispute with WestRock or KapStone regarding the terms of the relevant lease agreement, 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. We are also dependent on third parties for the disposal of brine, which results from our own conversion of BLSS into CTO. If these service providers do not perform under their contracts, the costs of disposing of brine ourselves, including, for example, the transportation costs, could be significant. Work stoppages and other labor relations matters may have an adverse effect on our financial condition and results of operations. A number of our employees are governed by collective bargaining agreements (“CBAs”). From time to time the Company engages in negotiations to renew CBAs as those contracts are scheduled to expire. During 2017, we ratified new labor agreements with the International Brotherhood of Electrical Workers (“IBEW”) and the Covington Paperworkers Union (“CPU”) at our Covington, Virginia location and the United Steel Workers (“USW”) at our Wickliffe, Kentucky location. The CBAs with the USW, representing 103 production and maintenance employees; the IBEW, representing eight instrument and electrical workers; and the International Association of Machinists and Aerospace Workers (“IAM”), representing five maintenance employees at our North Charleston, South Carolina plant, will expire on June 30, 2018. We have begun to prepare for bargaining with all three unions representing employees at the North Charleston plant in 2018. 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 23 Index stoppages, labor difficulties or unfavorable terms. If we were to experience any extended interruption of operations at any of our facilities as a result of strikes or other work stoppages, our results of operations and financial condition could be materially and adversely affected. In addition, due to the co-location of our Covington, Virginia and North Charleston, South Carolina facilities within the WestRock Paper Mill and KapStone Paper Mill facilities, a strike or work stoppage at either of those facilities could cause disruptions at our facilities, and our results of operations could be materially and adversely affected. Our business involves hazards associated with chemical manufacturing, storage, transportation and disposal. 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 the following potential hazards: 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 to our business, we may have inadequate insurance or cash flow to offset any associated costs. Such outcomes could adversely affect our financial condition and results of operations. Regulation of exposure to certain process chemicals could require expenditures or changes to our product formulations. Certain regulations applicable to our operations, including the Occupational Safety and Health Act and the Toxic Substances Control Act in the United States and the Registration, Evaluation and Authorization of Chemicals, or REACH, directive in Europe, prescribe limits restricting exposure to a number of chemicals used in our operations, including certain forms of formaldehyde, a raw material used in the manufacture of phenolic modified rosin-based ink resins and some lignin-based dispersants. Future studies on the health effects of chemicals used in our operations, including alkylphenols, such as bisphenol A, which are used in our TOR-based ink resins, may result in additional regulation or new requirements in the United States, Europe and elsewhere, which might further restrict or prohibit the use of, and exposure to, these chemicals. Additional regulation of or requirements for these or other 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. The Company’s operations are subject to a wide range of general and industry-specific environmental laws and regulations. The Company’s operations are subject to a wide range of general and industry-specific environmental laws and regulations, including, for example, related to bisphenol A, formaldehyde and air emissions. Changes in environmental laws and regulations, or their application, could subject the Company to significant additional capital expenditures and operating expenses in future years. However, any such changes are uncertain and, therefore, it is not possible for the Company 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. We are subject to cyber-security risks related to our intellectual property and certain other data. We use information technologies to retain certain of our intellectual property, as well as to securely manage operations and various business functions. Our systems are potentially subject to attempts by third parties to access information or to disrupt our systems. Despite our security design and controls, and those of our third-party providers, we could become subject to cyber- attacks which could result in operational disruptions or the misappropriation of sensitive data. There can be no assurance that such disruptions or misappropriations and the resulting repercussions will not be material to our financial condition or results of operations. We are dependent on certain 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 both segments) accounted for 37% of total sales for 2017. No customer accounted for more than 10% of total sales for 2017. With some exceptions, our business with those large customers is based 24 Index 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 business prospects, financial condition and results of operations would be materially adversely affected. Challenges in the commercial and credit environment may materially adversely affect Ingevity’s future access to capital. Ingevity’s 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 Ingevity’s products or in the solvency of its 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 Ingevity’s ability to gain access to the capital markets, which could have a material adverse effect on Ingevity’s competitive position, business, financial condition, results of operations and cash flows. Our current level of debt could adversely affect our financial health and prevent us from fulfilling our debt obligations. Our debt requires significant interest and principal payments. Our ability to make scheduled payments on or to refinance our debt obligations and to fund working capital, planned capital expenditures and expansion efforts and any strategic alliances or acquisitions we may make in the future depends on our ability to generate cash in the future and our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business, regulatory and other factors beyond our control. There can be no assurance that we will maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our debt. If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital or restructure or refinance our debt, including the notes. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. If our operating results and available cash are insufficient to meet our debt service obligations, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. We may not be able to consummate those dispositions or to obtain the proceeds sought from them, and these proceeds may not be adequate to meet any debt service obligations then due. Further, we may need to refinance all or a portion of our debt on or before maturity, and there can be no assurances we will be able to refinance any of our debt on commercially reasonable terms or at all. Any inability to generate sufficient cash flow or refinance our indebtedness on favorable terms could have a material adverse effect on our business, results of operations, and financial condition. The inability to make or effectively integrate future acquisitions may affect our results. As part of our growth strategy, we may pursue acquisitions of complementary businesses and product lines (including our planned acquisition of the Pine Chemicals Business) or invest in joint ventures. The ability to grow through acquisitions or other investments depends upon our ability to identify, negotiate, complete and integrate suitable acquisitions or joint venture arrangements. If we fail to successfully integrate acquisitions into our existing business, our financial condition and results of operations could be adversely affected. Ingevity may not be able to engage in certain corporate actions under the terms of the Tax Matters Agreement. To preserve the tax-free treatment to WestRock of the Separation and the distribution, under the tax matters agreement that Ingevity entered into with WestRock (the “Tax Matters Agreement”) Ingevity and its subsidiaries are restricted from taking or failing to take any action that prevents the distribution and/or certain related transactions from being tax-free for U.S. federal income tax purposes. Under the Tax Matters Agreement, prior to or on the 25-month anniversary of the Distribution Date, Ingevity is prohibited, except in certain circumstances, from: • entering into any transaction resulting in the acquisition of 50% or more of its stock (by vote or value, taking into account the stock indirectly acquired by the stockholders of Rock-Tenn Company (“Rock-Tenn”) in the combination (the “Merger”) of MeadWestvaco Corporation and Rock-Tenn, completed on July 1, 2015) or a substantial portion of its assets, whether by merger or otherwise; • merging, consolidating, dissolving or liquidating, or permitting any of its subsidiaries to merge, consolidate, dissolve or liquidate; • • issuing equity securities beyond certain thresholds; taking any action affecting the relative voting rights of Ingevity stock; 25 Index • • redeeming or repurchasing its capital stock beyond certain thresholds; and ceasing to actively conduct certain businesses. These restrictions may limit Ingevity’s ability to pursue certain strategic transactions or other transactions that it may believe to be in the best interests of its stockholders or that might increase the value of its business. In addition, under the Tax Matters Agreement, Ingevity is required to indemnify WestRock against any of WestRock’s tax liabilities as a result of the acquisition of Ingevity’s stock or assets, even if Ingevity did not participate in or otherwise facilitate the acquisition. We are subject to continuing contingent tax-related liabilities of WestRock. Under the U.S. Internal Revenue Code of 1986, as amended (the “Code”), each corporation that was a member of WestRock’s consolidated tax reporting group during any taxable period or portion of any taxable period ending on or before the effective time of the distribution is severally liable for the U.S. federal income tax liability of the entire consolidated tax reporting group for such taxable period. In connection with the Separation, we entered into the Tax Matters Agreement with WestRock that allocates the responsibility for prior period taxes of WestRock’s consolidated tax reporting group between Ingevity and WestRock. If WestRock were unable to pay any prior period taxes for which it is responsible, however, we could be required to pay the entire amount of such taxes, and such amounts could be significant. The Tax Matters Agreement generally gives WestRock discretion to handle consolidated tax returns and audits for pre-distribution periods in a manner which may be unfavorable to us and which may result in additional tax costs to us. Our accounting and other management systems and resources may not be adequately prepared to meet the financial reporting and other requirements to which we are subject following the Separation. Our financial results previously were included within the consolidated results of WestRock, and our reporting and control systems were appropriate for those of subsidiaries of a public company. Prior to the Separation, we were not directly subject to reporting and other requirements of the Exchange Act and Section 404 of the Sarbanes-Oxley Act of 2002. Following the Separation, we are subject to such reporting and other requirements, which require, among other things, annual management assessments of the effectiveness of our internal controls over financial reporting and a report by our independent registered public accounting firm addressing these assessments. These and other obligations place significant demands on our management, administrative and operational resources, including accounting and Information Technology resources. To comply with these requirements, we have upgraded and continue to upgrade our systems, including computer hardware infrastructure, implementation of additional financial and management controls, reporting systems and procedures, and we continue to hire additional accounting, finance and Information Technology staff. If we are unable to upgrade our financial and management controls, reporting systems, Information Technology and procedures in a timely and effective fashion, our ability to comply with our financial reporting requirements and other rules that apply to reporting companies could be impaired. Any failure to achieve and maintain effective internal controls could have an adverse effect on our business, financial condition, results of operations and cash flows. Our tax rate is dependent upon a number of factors; a change in any of which could impact our future tax rates and net income. Our future tax rates may be adversely affected by a number of factors, including: future changes in the jurisdictions in which our profits are determined to be earned and taxed; changes in estimated realization of our deferred tax assets; the repatriation of non-U.S. earnings for which we have not previously provided U.S. income and non-U.S. withholding taxes; adjustments to estimated taxes upon finalization of various tax returns; increases in expenses that are non-deductible for tax purposes; changes in available tax credits; the resolution of issues arising from tax audits with various tax authorities; and changes in tax laws or interpretation of such tax laws. Losses for which no tax benefits can be recorded could materially impact our tax rate and its volatility from one quarter to another. Our planned acquisition of Georgia Pacific's ("GP") Pine Chemical Business may not occur in the expected time frame, which may negatively affect the benefits we expect to obtain from the transaction and increase transaction costs, or may not occur at all. The Agreement for the Acquisition contains customary representations, warranties, indemnities and closing conditions (including the expiration or early termination of the waiting period under the HSR Act, and receipt of other required antitrust approvals in certain foreign jurisdictions). On November 9, 2017, the Company received a request for additional information and documentary material, often referred to as a “second request,” from the Federal Trade Commission ("FTC") in connection with the Agreement. The second request was issued under the Hart-Scott-Rodino Antitrust Improvements Act, or "HSR Act." GP 26 Index received a similar second request from the FTC in connection with the Acquisition. Consummation of the Acquisition is conditioned on expiration of the waiting period applicable under the HSR Act, among other conditions. Issuance of a second request is a standard part of the regulatory approval process for transactions of this type. The effect of the second request is to extend the waiting period under the HSR Act until 30 days after all parties to the Agreement have substantially complied with the second request, unless the waiting period is terminated earlier by the FTC or the parties voluntarily extend the time for closing. The Company will continue to work closely and cooperatively with the FTC and currently anticipates closing the Acquisition in the first quarter of 2018, assuming receipt of FTC clearance. Completion of the Acquisition is subject to the satisfaction or waiver of a number of other conditions as set forth in the Agreement, including the receipt of certain governmental approvals. We and GP may not be able to satisfy the closing conditions; closing conditions beyond our or their control may not be satisfied or waived and the Acquisition may not be consummated by reason of failure to satisfy such conditions. If the Acquisition is not completed within the expected time frame, such delay could result in additional transaction costs, termination fees, loss of revenue or other effects associated with uncertainty about the Acquisition, as well as could negatively affect the benefits we expect to obtain from the Acquisition. We may not realize the growth opportunities and cost synergies that are anticipated from the Acquisition. The benefits that are expected to result from the Acquisition will depend, in part, on our ability to realize the anticipated growth opportunities and the expected synergies derived from manufacturing optimization and lower logistic costs. Our success in realizing these growth opportunities and synergies, and the timing of this realization, depends on the successful integration of the Pine Chemical Business. There is a significant degree of difficulty and management distraction inherent in the process of integrating an acquisition as sizable as the Pine Chemical Business. The process of integrating operations could cause an interruption of, or loss of momentum in, our and the Pine Chemical Business’ activities. Members of our senior management may be required to devote considerable amounts of time to this integration process, which will decrease the time they will have to manage other aspects of our business, service existing customers, attract new customers and develop new products or strategies. If senior management is not able to effectively manage the integration process, or if any significant business activities are interrupted as a result of the integration process, our business could suffer. There can be no assurance that we will successfully or cost-effectively integrate the Pine Chemical Business. The failure to do so could have a material adverse effect on our business, financial condition or results of operations. Even if we are able to integrate the Pine Chemical Business successfully, this integration may not result in the realization of the full benefits of the growth opportunities and synergies that we currently expect from this integration, and we cannot guarantee that these benefits will be achieved within anticipated time frames or at all. For example, we may not be able to achieve the expected synergies from manufacturing optimization and lower logistics costs, or the associated costs may be greater than we expect. Any of these would offset the anticipated benefits from the planned Acquisition. Risks Relating to Ingevity’s Common Stock The price of Ingevity’s common stock may fluctuate significantly. The market price of Ingevity common stock may fluctuate significantly due to a number of factors, some of which may be beyond Ingevity’s control, including: • • • • • actual or anticipated fluctuations in Ingevity’s operating results; changes in earnings estimated by securities analysts or Ingevity’s ability to meet those estimates; the operating and stock price performance of comparable companies; changes to the regulatory and legal environment under which Ingevity operates; and domestic and worldwide economic conditions. We cannot guarantee the timing, amount or payment of any dividends on our common stock in the future. The payment and amount of any dividend is subject to the sole discretion of our board of directors and will depend upon many factors, including our financial condition and prospects, our capital requirements and access to capital markets, covenants 27 Index associated with certain of our debt obligations, legal requirements and other factors that our board of directors may deem relevant, and there can be no assurances that we will pay a dividend. Your percentage of ownership in Ingevity may be diluted in the future. A stockholder's percentage ownership in Ingevity may be diluted because of equity issuances for acquisitions, capital market transactions or otherwise, including, without limitation, equity awards that we may be granting to our directors, officers and employees. Such awards will have a dilutive effect on Ingevity’s earnings per share, which could adversely affect the market price of Ingevity’s common stock. From time to time, Ingevity will issue additional options or other stock-based awards to certain employees under Ingevity’s employee benefits plans. In addition, Ingevity’s amended and restated certificate of incorporation authorizes Ingevity to issue, without the approval of Ingevity’s stockholders, one or more classes or series of preferred stock having such designation, powers, preferences and relative, participating, optional and other special rights, including preferences over Ingevity’s common stock respecting dividends and distributions, as Ingevity’s board of directors generally may determine. The terms of one or more classes or series of preferred stock could dilute the voting power or reduce the value of Ingevity’s common stock. For example, Ingevity could grant the holders of preferred stock the right to elect some number of Ingevity’s directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences Ingevity could assign to holders of preferred stock could affect the residual value of the common stock. Certain provisions in Ingevity’s amended and restated certificate of incorporation and amended and restated bylaws, and of Delaware law, may prevent or delay an acquisition of Ingevity, which could depress the trading price of Ingevity’s common stock. Ingevity’s amended and restated certificate of incorporation and amended and restated bylaws contain, and Delaware law contains, provisions that are intended to deter coercive takeover practices and inadequate takeover bids by making such practices or bids unacceptably expensive to the bidder and to encourage prospective acquirers to negotiate with Ingevity’s board of directors rather than to attempt a hostile takeover. These provisions include, among others: • • • • • • • the inability of Ingevity’s stockholders to act by written consent; rules regarding how stockholders may present proposals or nominate directors for election at stockholder meetings; the right of Ingevity’s board to issue preferred stock without stockholder approval; the ability of Ingevity’s remaining directors to fill vacancies on Ingevity’s board of directors; the separation of Ingevity’s board of directors into three classes of directors, which classification will terminate beginning at the Company’s 2019 annual meeting; the inability of Ingevity’s stockholders to remove directors other than for cause while the board is classified; and the requirement that the affirmative vote of holders of at least 75% of Ingevity’s outstanding voting stock is required to amend certain provisions of Ingevity’s amended and restated certificate of incorporation and amended and restated bylaws. In addition, because Ingevity has not chosen to be exempt from Section 203 of the Delaware General Corporation Law (the “DGCL”), this provision could also delay or prevent a change of control that you may favor. Section 203 provides that, subject to limited exceptions, persons that acquire, or are affiliated with persons that acquire, more than 15% of the outstanding voting stock of a Delaware corporation shall not engage in any business combination with that corporation, including by merger, consolidation or acquisitions of additional shares, for a three-year period following the date on which that person or its affiliates becomes the holder of more than 15% of the corporation’s outstanding voting stock. Ingevity believes these provisions will protect its stockholders from coercive or otherwise unfair takeover tactics by requiring potential acquirers to negotiate with Ingevity’s board of directors and by providing Ingevity’s board of directors with more time to assess any acquisition proposal. These provisions are not intended to make Ingevity immune from takeovers. However, these provisions will apply even if the offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that Ingevity’s board of directors determines is not in the best interests of Ingevity and Ingevity’s stockholders. These provisions may also prevent or discourage attempts to remove and replace incumbent directors. 28 Index There could be significant liability if the separation were determined to be a taxable transaction. In connection with the separation, our former parent received an opinion from outside tax counsel to the effect that the requirements for tax-free treatment under Section 355 of the Code would be satisfied. The opinion relied on certain facts, assumptions, representations and undertakings from our former parent and us regarding the past and future conduct of the companies’ respective businesses and other matters. If any of these facts, assumptions, representations or undertakings were incorrect or not satisfied, we and our stockholders may not be able to rely on the opinion of tax counsel and could be subject to significant tax liabilities. Notwithstanding the opinion of tax counsel, the IRS could determine upon audit that the separation is taxable if it determines that any of these facts, assumptions, representations or undertakings were incorrect or violated or if it disagrees with the conclusions in the opinion, or for other reasons, including as a result of certain significant changes in the share ownership of our company or our former parent after the separation. If the separation were determined to be taxable for U.S. federal income tax purposes, our former parent and its stockholders that are subject to U.S. federal income tax could incur significant U.S. federal income tax liabilities, and we could incur significant liabilities. Ingevity’s amended and restated bylaws designate the state courts within the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by Ingevity’s stockholders, which could discourage lawsuits against Ingevity and Ingevity’s directors and officers. Ingevity’s amended and restated bylaws provide that unless the board of directors otherwise determines, a state court within the State of Delaware will be the sole and exclusive forum for any derivative action or proceeding brought on behalf of Ingevity, any action asserting a claim of breach of a fiduciary duty owed by any director of officer of Ingevity to Ingevity or Ingevity’s stockholders, creditors or other constituents, any action asserting a claim against Ingevity or any director or officer of Ingevity arising pursuant to any provision of the DGCL, or Ingevity’s amended and restated certificate of incorporation or bylaws, or any action asserting a claim against Ingevity or any director or officer of Ingevity governed by the internal affairs doctrine. However, if no state court located within the State of Delaware has jurisdiction, the action may be brought in the federal district court for the District of Delaware. Although Ingevity’s amended and restated bylaws include this exclusive forum provision, it is possible that a court could rule that this provision is inapplicable or unenforceable. This exclusive forum provision may limit the ability of Ingevity’s stockholders to bring a claim in a judicial forum that such stockholders find favorable for disputes with Ingevity or Ingevity’s directors or officers, which may discourage such lawsuits against Ingevity and Ingevity’s directors and officers. Alternatively, if a court were to find this exclusive forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings described above, Ingevity may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect Ingevity’s business, financial condition or results of operations.

Recent Developments 2018 Senior Notes On January 24, 2018, we issued $300.0 million aggregate principal amount of 4.50 percent senior unsecured notes due 2026 (the “Notes”). The Notes were issued pursuant to an indenture dated as of January 24, 2018 (the “Indenture”), by and among Ingevity, the subsidiary guarantors party thereto and U.S. Bank National Association, as trustee. The Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A and to certain non-U.S. persons outside the U.S. pursuant to Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). The Notes have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the U.S. absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws. The net proceeds from the sale of the Notes, after deducting deferred financing fees of $5.6 million, were approximately $294.4 million. We intend to use the net proceeds from the sale of the Notes to finance our planned purchase of substantially all the assets primarily used in the pine chemicals business of Georgia-Pacific Chemicals LLC and Georgia-Pacific LLC and for general corporate purposes. Interest payments on the Notes are due semiannually in arrears on February 1st and August 1st of each year, beginning on August 1, 2018, at a rate of 4.50 percent per year. The Notes will mature on February 1, 2026. The Indenture contains certain customary covenants (including covenants limiting Ingevity and our 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 our 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 36 periods). The occurrence of an event of default under the Indenture could result in the acceleration of the Notes and could cause a cross-default that could result in the acceleration of other indebtedness of Ingevity and our subsidiaries. Pending Georgia Pacific's Pine Chemical Business Acquisition On August 22, 2017, we entered into the Purchase Agreement with GP and Ingevity Arkansas, LLC, a wholly-owned subsidiary of Ingevity, to purchase Pine Chemical Business, including assets and facilities related to tall oil fractionation operations and the production or modification of tall oil fatty acids, tall oil rosins, rosin derivatives and formulated products. The purchase price for the Acquisition is $315 million, subject to a customary adjustment to reflect normalized working capital for the Pine Chemical Business. In addition to the purchase price, at the closing of the Acquisition, we will assume certain liabilities related to the Pine Chemical Business. The closing of the Acquisition is subject to regulatory clearance and other customary closing conditions, which are currently ongoing. We intend to use the net proceeds from the $300.0 million senior unsecured notes issued on January 24, 2018, to finance the Acquisition. Pursuant to the Purchase Agreement, GP has agreed to indemnify the Company for losses resulting from a breach of certain representations and warranties and excluded liabilities, subject to certain limitations. Furthermore, the Purchase Agreement contains various termination provisions available to the parties thereto. In addition, at the closing of the Acquisition, the Company and GP intend to enter into certain transition and shared services agreements to effectuate the transfer of the assets pursuant to the Acquisition. Separately, at the closing of the Acquisition, Ingevity and GP will also enter into a supply agreement, whereby certain GP paper mills will supply CTO to Ingevity at market-based prices for a term of 20 years. Separation and Distribution On May 15, 2016 (the "Distribution Date"), WestRock Company (“WestRock”) completed the previously announced separation of the business comprising WestRock's Specialty Chemicals reporting segment, and certain other assets and liabilities, into Ingevity, a separate public company (herein referred to as the "Separation"). The Separation was completed by way of a distribution of all of the then outstanding shares of common stock of Ingevity through a dividend in kind of Ingevity's common stock (par value $0.01) to holders of record of WestRock common stock (par value $0.01) as of the close of business of May 4, 2016 (the "Record Date"). On the Distribution Date, each holder of WestRock's common stock received one share of Ingevity's common stock for every six shares of WestRock's common stock held on the Record Date. The Separation was completed pursuant to a Separation and Distribution Agreement and other agreements with WestRock related to the Separation, including an Employee Matters Agreement ("EMA"), a Tax Matters Agreement, a Transition Services Agreement and an Intellectual Property Agreement (collectively, the "Separation Agreements"), each of which was filed as an exhibit to our Current Report on Form 8-K, filed with the Securities and Exchange Commission on May 16, 2016. The Separation Agreements govern the relationship among Ingevity and WestRock following the Separation and provide for the allocation of various assets, liabilities, rights and obligations. The Separation Agreements also include arrangements for transition services to be provided by WestRock to Ingevity. The Registration Statement was declared effective by the SEC on April 25, 2016, and Ingevity's common stock began "regular-way" trading on the New York Stock Exchange ("NYSE") on May 16, 2016, under the symbol "NGVT". Unless the context otherwise requires, references to "we," "us," "our," "Ingevity" and the "Company" refer to Ingevity Corporation and its consolidated subsidiaries after giving effect to the Separation. 37 Results of Operations In millions, except per share data Net sales Cost of sales Gross profit Selling, general and administrative expenses Research and technical expenses Separation costs Restructuring and other (income) charges, net Acquisition costs Other (income) expense, net Interest expense Interest income Income (loss) before taxes Provision (benefit) for income taxes Net income (loss) Years Ended December 31, 2017 2016 2015 $ 972.4 $ 908.3 $ 643.4 329.0 106.4 19.8 0.9 3.7 7.1 0.5 18.1 (2.3) 174.8 29.6 145.2 18.7 126.5 $ 633.9 274.4 96.4 17.6 17.5 41.2 — (3.2) 19.3 (1.4) 87.0 42.6 44.4 9.2 35.2 $ 958.3 682.9 275.4 92.7 17.4 17.2 (7.5) — (1.0) 20.1 — 136.5 52.2 84.3 4.6 79.7 Less: Net income (loss) attributable to noncontrolling interests Net income (loss) attributable to Ingevity stockholders $ Net Sales Comparison of Years Ended December 31, 2017, 2016 and 2015 In millions Year Ended December 31, 2017 Year Ended December 31, 2016 Year Ended December 31, 2017 vs. 2016 Percentage change vs. prior year Net sales $ 972.4 908.3 Total change 7% (5)% Currency effect —% —% Price/Mix (1)% (3)% Volume 8% (2)% Net sales were $972.4 million and $908.3 million for the years ended December 31, 2017 and 2016, respectively. The sales increase in 2017 was driven by favorable volume of $72.7 million (eight percent of sales). Performance Materials and Performance Chemicals contributed $54.5 million and $18.2 million, respectively, to the volume impacts during the year. The sales increase was tempered by unfavorable pricing and product mix of $7.6 million (one percent of sales) across both segments, as well as unfavorable foreign exchange impacts of $1.0 million. Year Ended December 31, 2016 vs. 2015 Net sales were $908.3 million and $958.3 million for the years ended December 31, 2016 and 2015, respectively. The sales decrease in 2016 was driven by a volume decline of $59.5 million (six percent of sales) across all Performance Chemicals' product lines as well as unfavorable pricing and product mix of $34.7 million (four percent of sales) in certain industrial specialties and oilfield technologies products within Performance Chemicals and $0.2 million in Performance Materials due to pricing pressure from competing materials and foreign exchange of $1.0 million. The sales decrease was partially offset by volume gains of $43.4 million (five percent of sales) in Performance Materials due to strong growth in high content vehicle production for sale into the North American automotive market and increased vehicle content due to regulatory adoption, favorable pricing and product mix of $2.0 million in Performance Chemicals' pavement technologies. 38 Cost of sales Year Ended December 31, 2017 vs. 2016 Cost of sales were $643.4 million (66% of sales) and $633.9 million (70 percent of sales) for the years ended December 31, 2017 and 2016, respectively. Increased cost of sales was driven by the sales volume increase resulting in a $31.2 million increase to cost of sales and depreciation and amortization of $0.5 million. These increases were partially offset by lower input costs related to petroleum-based raw materials, energy, and CTO impacting cost of sales by $14.1 million, manufacturing-related spending of $8.0 million due to favorable productivity costs and reduced cost of sales in foreign locations stemming from the strength of the U.S. dollar of $0.1 million. Year Ended December 31, 2016 vs. 2015 Cost of sales were $633.9 million (70% of sales) and $682.9 million (71 percent of sales) for the years ended December 31, 2016 and 2015, respectively. Reduced cost of sales was driven by sales volume declines resulting in a $35.8 million reduction to cost of sales, lower input costs related to petroleum-based raw materials, energy, and CTO impacting cost of sale by $19.9 million, and reduced cost of sales in foreign locations stemming from the strength of the U.S. dollar of $1.8 million. These decreases were partially offset by increased depreciation and amortization of $4.2 million and manufacturing-related spending of $4.3 million due to unfavorable productivity costs, a portion of which related to the startup of our Performance Materials’ activated carbon manufacturing facility in Zhuhai, China. Selling, general and administrative expenses Year Ended December 31, 2017 vs. 2016 Selling, general and administrative ("SG&A") expenses were $106.4 million (11 percent of sales) and $96.4 million (11 percent of sales) for the years ended December 31, 2017 and 2016, respectively. The increase in SG&A is primarily due to higher incentive compensation costs driven by the improvements in gross profit as compared to the prior period. Increased gross profit translates into higher Adjusted EBITDA which is our primary metric for incentive-based compensation. Adjusted EBITDA is defined under the section entitled "Use of Non-GAAP Financial Measures" within this MD&A. SG&A expenses as a percentage of sales were relatively flat year over year. Year Ended December 31, 2016 vs. 2015 SG&A expenses were $96.4 million (11 percent of sales) and $92.7 million (10 percent of sales) for the years ended December 31, 2016 and 2015, respectively. SG&A expenses increased due to higher employee-related costs partially offset by cost reduction initiatives that commenced in early 2016. Separation costs Year Ended December 31, 2017 vs. 2016 Separation costs of $0.9 million and $17.5 million for the years ended December 31, 2017 and 2016, respectively, were expenses related to the Separation. See Note 14 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information. Year Ended December 31, 2016 vs. 2015 Separation costs of $17.5 million and $17.2 million for the years ended December 31, 2016 and 2015, respectively, were expenses related to the Separation. See Note 14 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information. 39 Restructuring and other (income) charges, net 2017 activities In January 2017, we initiated a reorganization to streamline our leadership team, flatten the organization and reduce costs. As a result of this reorganization, we recorded $1.3 million, in severance and other employee-related costs for the year ended December 31, 2017. During the year ended December 31, 2017, we also recorded $2.4 million of additional miscellaneous exit costs primarily associated with the exit of our Performance Chemicals' manufacturing operations in Palmeira, Santa Catarina, Brazil which began in the fourth quarter of 2016 (see 2016 activities below). 2016 activities As a result of continued deteriorating market conditions within the South America region, on October 31, 2016, our Board of Directors approved a plan to exit our Performance Chemicals' manufacturing operations in Palmeira, Santa Catarina, Brazil. As a result, we recorded a non-cash pre-tax impairment charge to property, plant and equipment in the amount of $30.2 million and recorded severance costs of $1.8 million. The severance costs began to be paid in the fourth quarter of 2016. Refinery production ceased before year end and the facility was decommissioned in 2017. We recorded $2.6 million of additional miscellaneous exit costs during the year ended December 31, 2016. During the first quarter of 2016, we announced the closure of the Performance Chemicals' derivatives operation in Duque de Caxias, Rio de Janeiro, Brazil. As a result of this closure, we recorded $0.1 million impairment charge on fixed assets, $1.8 million in severance and other employee-related costs and $1.7 million of additional miscellaneous exit costs during year ended December 31, 2016. During the first quarter of 2016, we also announced a company-wide restructuring to better align our workforce in light of changing macroeconomic and market realities. The restructuring decision resulted in workforce reductions at several of our locations. As a result, during the year ended December 31, 2016, we recorded severance and other employee-related charges of $2.7 million ($1.9 million related to Performance Chemicals segment and $0.8 million related to Performance Materials segment). We also recorded an impairment charge on fixed assets of $0.3 million in the year ended December 31, 2016 (related to the Performance Chemicals segment). 2015 activities During 2015, we sold our 60 percent interest in a subsidiary in China for cash proceeds of $11.5 million and recorded a gain on the sales of the subsidiary of $10.3 million. Prior to its sale, this subsidiary operated under our Performance Materials operating segment. Additionally during 2015, we recognized income of $1.2 million associated with the sale of our Performance Materials' air purification business in 2014. As part of a plan that was implemented to restructure a portion of our operations during 2015, we recorded an impairment of $4.0 million to write down inventory and property, plant and equipment associated with certain manufacturing operations of our Performance Chemicals segment. 40 Detail on the restructuring charges and asset disposal activities is provided below.

Other Income primarily represents favorable developments on previously recorded exit costs as recoveries associated with restructuring activities. Acquisition costs Years Ended December 31, 2017, 2016, and 2015 Acquisition costs of $7.1 million, zero and zero for the years ended December 31, 2017, 2016 and 2015, respectively, were charges incurred in connection with the planned acquisition of GP's Pine Chemical Business. See Note 16 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information. Interest expense Interest expense was as follows for the years ended December 31, 2017, 2016, and 2015.

Interest income is primarily related to the interest earned on our restricted investment. Provision (benefit) for income taxes Additional detail explaining the change in the U.S. Generally Accepted Accounting Principles, or "GAAP", effective tax rate is presented in Note 17 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K. 41 Year Ended December 31, 2017 vs. 2016 The Company’s effective tax rate was 16.9 percent and 49.0 percent for the years ended December 31, 2017 and 2016, respectively. The decrease in our effective tax rate is mainly due to U.S. Tax Reform, which was enacted in December 2017 and non-deductible costs incurred in 2016 that did not recur in 2017. Due to U.S. Tax Reform, our U.S. net deferred tax liabilities as of December 31, 2017 were remeasured from 35 percent to 21 percent, resulting in $24.5 million of a provisional deferred income tax benefit and a reduction in our effective tax rate of 14.0 percent. The remaining difference in our effective tax rate for the year ended December 31, 2017 as compared to 2016 is due to non-deductible transaction costs incurred in 2016 associated with the Separation, higher restructuring and other (income charges) incurred in 2016 in legal entities with full valuation allowances and acquisition-related charges incurred in 2017. Excluding the impact of U.S.Tax Reform, separation costs, acquisition-related charges and restructuring and other (income charges) in legal entities with full valuation allowances the change in the effective tax rate period over period was primarily due to a shift in earnings mix as it relates to domestic versus foreign income earned. Foreign profits are generally taxed at lower rates compared to domestic income. See Note 17 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information. Year Ended December 31, 2016 vs. 2015 The Company’s effective tax rate was 49.0% and 38.2% for the years ended December 31, 2016 and 2015, respectively. The differences in these effective rates compared to the combined statutory rates were primarily due to non-deductible transaction costs associated with the Separation in 2016 and the unfavorable results of legal entities with full valuation allowances, including the $32.0 million charge associated with the exit of our refinery operations in Palmeira, Santa Catarina, Brazil. Excluding the impact of restructuring and other (income charges), separation costs and losses from legal entities with full valuation allowances the change in the effective tax rate period over period was primarily due to a shift in earnings mix as it relates to domestic versus foreign income earned. Foreign profits are generally taxed at lower rates compared to domestic income. See Note 17 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information. Net income (loss) attributable to noncontrolling interests Year Ended December 31, 2017, 2016, and 2015 Net income (loss) attributable to noncontrolling interests was $18.7 million, $9.2 million and $4.6 million for the years ended December 31, 2017, 2016, and 2015, respectively. Our noncontrolling interest represents the 30 percent ownership interest held by a third-party U.S.-based company in our consolidated Purification Cellutions LLC legal entity. Purification Cellutions LLC is the legal entity that manufactures our structured honeycomb products within our Performance Materials segment. Refer to the Performance Materials’ operating profit discussion below within the Segment Operating Results section for further discussion of the segment’s performance for the years ended December 31, 2017, 2016, and 2015. Net income (loss) attributable to Ingevity stockholders Year Ended December 31, 2017 vs. 2016 Net income (loss) attributable to Ingevity stockholders was $126.5 million and $35.2 million for the years ended December 31, 2017 and 2016, respectively. The year over year impact was primarily driven by a reduction in separation and restructuring and other charges of $54.1 million, slightly offset by acquisition-related charges of $7.1 million. The favorable impact of U.S. Tax Reform for 2017, compared to 2016, was a tax benefit of $24.5 million. Excluding these changes, Net income (loss) attributable to Ingevity stockholders increased by $22.1 million. This increase was primarily driven by strong segment operating profits from both segments, including an increase of $23.6 million in Performance Chemicals and $15.1 million in Performance Materials, offset by an increase in non-controlling interest of $9.5 million. Year Ended December 31, 2016 vs. 2015 Net income (loss) attributable to Ingevity stockholders was $35.2 million and $79.7 million for the years ended December 31, 2016 and 2015, respectively. This decrease of $44.5 million was primarily driven by the $32.0 million charge associated with the exit of our Performance Chemicals' refinery operations in Palmeira, Santa Catarina, Brazil as well as declines in segment 42 operating profit in Performance Chemicals of $29.9 million partially offset by increased segment operating profit in Performance Materials of $27.2 million and a tax provision which is lower by $9.6 million in 2016 compared to 2015. Segment Operating Results In addition to the information discussed above, the following sections discuss the results of operations for each of our segments. Our segments are (i) Performance Materials and (ii) Performance Chemicals. In general, the accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies in Note 3 to the Consolidated Financial Statements included within Part II.

Segment operating profit increased $23.6 million due to favorable manufacturing productivity of $27.3 million, as well as favorable volume of $7.5 million. These gains were offset by unfavorable foreign currency exchange impacts of $5.3 million, unfavorable SG&A expenses of $3.8 million, and unfavorable pricing and product mix of $2.1 million. Year Ended December 31, 2016 vs. 2015 Segment net sales for the Performance Chemicals segment were $607.3 million and $701.9 million for the years ended December 31, 2016 and 2015, respectively. The sales decrease was driven by volume declines of $59.5 million (eight percent of sales) driven by unfavorable volume in all Performance Chemicals' product lines, $34.7 million (five percent of sales) of unfavorable pricing and product mix in certain industrial specialties and oilfield technologies products due to pricing pressure from competing materials and $2.4 million of unfavorable foreign currency exchange. These decreases were partially offset by price and product mix growth of $2.0 million in high value strategic markets for pavement technologies compared to 2015. 44 Segment operating profit for the Performance Chemicals segment was $56.7 million and $86.6 million for the years ended December 31, 2016 and 2015, respectively. Segment operating profit decreased $28.7 million due to unfavorable pricing and product mix, $17.4 million due to lower sales volume, and $3.0 million due to reduced throughput partially offset by cost savings initiatives. These decreases were partially offset by $18.2 million of deflation on petroleum-based raw materials, energy and CTO compared to 2015 and $1.0 million of lower depreciation and amortization expense in 2016 compared to 2015. Use of Non-GAAP Financial Measures 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. These financial measures are not meant to be considered in isolation or as a substitute for the most directly comparable financial measure calculated in accordance with GAAP. The company believes these non-GAAP measures provide 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 and projected future results. Ingevity uses the following non-GAAP measures: Adjusted EBITDA is defined as net income (loss) plus interest expense, net, provision (benefit) for income taxes, separation costs, restructuring and other (income) charges, net, acquisition costs and depreciation and amortization. Segment EBITDA is defined as segment operating profit plus depreciation and amortization. We use the above financial measures as the primary measures of profitability used by managers of the business and its segments. In addition, we believe Adjusted EBITDA and Segment EBITDA are useful measures because they exclude the effects of financing and investment activities as well as non-operating activities. These non-GAAP financial measures are 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. Reconciliations of these non-GAAP financial measures are set forth within this section.

Total Company Outlook and 2018 Guidance For revenue, favorable volume in Performance Materials and Performance Chemicals oilfield and pavement technologies are expected to be partially offset by negative volume in Performance Chemicals industrial specialties applications as we continue to derivatize higher quantities of TOFA into oilfield and pavement products. We expect to deliver fiscal year 2018 Net sales of $1.07 billion to $1.13 billion. 2018 Adjusted EBITDA is expected to grow by 17% to 26%, which includes expected closure of the Acquisition. This is driven by mix improvement due to volume growth in our higher margin Performance Materials and Performance Chemicals pavement technologies applications, volume growth in oilfield technologies, favorable year over year CTO costs, partially offset by reduced volume in industrial specialties. Some risks to the 2018 outlook include reductions in U.S. vehicle sales and production in automotive applications, higher non-CTO raw materials costs with higher oil prices, a shift towards smaller vehicles in the U.S. (versus the 2016 and 2017 shift towards light-trucks), lower automotive product sales in China driven by a reduction in tax incentives versus 2017, lower oil prices and a reduction in oil drilling and production in oilfield technologies, and a delay in the Georgia- Pacific Pine Chemicals acquisition. We expect to deliver fiscal year 2018 Adjusted EBITDA of $285 million to $305 million. A reconciliation of Net income to Adjusted EBITDA as projected for 2018 is not provided because we do not forecast Net income as we cannot, without unreasonable effort, estimate or predict with certainty various components of Net income. These components, net of tax, include additional separation costs associated with the separation from WestRock; further restructuring and other income (charges); acquisition-related charges in connection with the planned acquisition of Pine Chemical Business; and revisions due to future guidance and assessment of U.S. Tax Reform. 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 Net income (loss) attributable to Ingevity stockholders and Adjusted EBITDA. Liquidity and Capital Resources The primary source of liquidity for Ingevity’s business is the cash flow provided by operations, which has historically been transferred to WestRock to support its overall cash management strategy. Transfers of cash to and from WestRock prior to the Separation have been reflected in Net parent investment in the historical consolidated balance sheets, statements of cash flows and statements of stockholders' equity. Cash and cash equivalents totaled $87.9 million at December 31, 2017. Management continuously monitors deposit concentrations and the credit quality of the financial institutions that hold Ingevity's cash and cash equivalents, as well as the credit quality of its 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, 2017 included $18.0 million held by our foreign subsidiaries. Cash and earnings of our foreign subsidiaries are generally used to finance our foreign operations and capital expenditures. We believe that our foreign holdings of cash will not have a material adverse impact on our U.S. liquidity. Management does not currently expect to repatriate cash earnings from our foreign operations in order to fund U.S. operations. 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 potentially 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 United States. Revolving Credit and Term Loan Facility Amendment On August 21, 2017, we entered into an Incremental Facility Agreement and Amendment No. 1 (the "Amendment") to our existing Credit Agreement, dated as of March 7, 2016 (the "Existing Credit Agreement"). The Amendment established 47 incremental term loan commitments in the aggregate principal amount of $75.0 million and increased the revolving commitments under our Existing Credit Agreement by $150.0 million. The Amendment also extended the maturity date for the loans and commitments under the Existing Credit Agreement by one year, to May 9, 2022. The Amendment was entered to consummate the planned acquisition of Pine Chemical Business. 2018 Senior Notes On January 24, 2018, we issued $300.0 million aggregate principal amount of 4.50 percent senior unsecured notes due 2026 (the “Notes”). The Notes were issued pursuant to an indenture dated as of January 24, 2018 (the “Indenture”), by and among Ingevity, the subsidiary guarantors party thereto and U.S. Bank National Association, as trustee. The Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A and to certain non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). The Notes have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws. The net proceeds from the sale of the Notes, after deducting deferred financing fees of $5.6 million were approximately $294.4 million. We intend to use the net proceeds from the sale of the Notes to finance our planned purchase of substantially all the assets primarily used in the pine chemicals business of Georgia-Pacific Chemicals LLC and Georgia-Pacific LLC and for general corporate purposes. Interest payments on the Notes are due semiannually in arrears on February 1st and August 1st of each year, beginning on August 1, 2018, at a rate of 4.50 percent per year. The Notes will mature on February 1, 2026. The Indenture contains certain customary covenants (including covenants limiting Ingevity and our 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 our 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 Indenture could result in the acceleration of the Notes and could cause a cross-default that could result in the acceleration of other indebtedness of Ingevity and our subsidiaries. Other Potential Liquidity Needs Georgia Pacific's Pine Chemical Business On August 22, 2017, we entered into the Purchase Agreement with GP and Ingevity Arkansas, LLC, a wholly-owned subsidiary of Ingevity, to purchase substantially all the assets primarily used in the Pine Chemical Business, including assets and facilities related to tall oil fractionation operations and the production or modification of tall oil fatty acids, tall oil rosins, rosin derivatives and formulated products. The purchase price for the Acquisition is $315 million, subject to a customary adjustment to reflect normalized working capital for the Pine Chemical Business. In addition to the purchase price, at the closing of the Acquisition, we will assume certain liabilities related to the Pine Chemical Business. The closing of the Acquisition is subject to regulatory clearance and other customary closing conditions, which are currently ongoing. We intend to use the net proceeds from the $300.0 million senior unsecured notes issued on January 24, 2018, to finance the Acquisition. Pursuant to the Purchase Agreement, GP has agreed to indemnify the Company for losses resulting from a breach of certain representations and warranties and excluded liabilities, subject to certain limitations. Furthermore, the Purchase Agreement contains various termination provisions available to the parties thereto. In addition, at the closing of the Acquisition, the Company and GP intend to enter into certain transition and shared services agreements to effectuate the transfer of the assets pursuant to the Acquisition. Separately, at the closing of the Acquisition, Ingevity and GP will also enter into a supply agreement, whereby certain GP paper mills will supply CTO to Ingevity at market- based prices for a term of 20 years. Share Repurchases On February 20, 2017, our Board of Directors authorized the repurchase of up to $100.0 million of our common stock. As of December 31, 2017, we have repurchased $6.6 million, which leaves $93.4 million remaining available for repurchase. The repurchase program does not include a specific timetable or price targets and may be suspended or terminated at any time. Shares 48 may be purchased through open market or privately negotiated transactions at the discretion of management based on its evaluation of prevailing market conditions and other factors. Capital Expenditures Projected 2018 capital expenditures are expected to be $80 million to $90 million. We have no material commitments associated with these projected capital expenditures as of December 31, 2017.

For the years ended December 31, 2017 and 2016, capital spending included base maintenance capital supporting ongoing operations and growth spending, primarily related to the construction of an activated carbon manufacturing facility in China and new Performance Chemicals derivative equipment in North Charleston, South Carolina supporting the adhesives, pavement and oilfield markets. For the year ended December 31, 2016, cash used in investing activities was primarily related to $69.7 million invested in a trust. In accordance with the Separation Agreements, we used a portion of the proceeds from our debt borrowing to be held in a restricted trust. The trust, presented as restricted investment on our consolidated balance sheet, was to secure the principal payment under our $80.0 million capital lease obligation which is payable upon maturity in 2027.

Item 8 of this Form 10-K for more information on our Revolving Credit and Term Loan Facility Amendment), noncontrolling interest distributions of $12.3 million, and $6.6 million to repurchase shares according the publicly announced Share Repurchase program. Cash used by financing activities in the year ended December 31, 2016 was $3.4 million, and was driven by net borrowings of $402.5 million (refer to Note 9 in the Consolidated Financial Statements for more information) and an inflow from transactions with WestRock of $51.9 million offset by a distribution to WestRock at Separation of $448.5 million. As WestRock managed the Company’s cash and financing arrangements before the Separation, all excess cash generated through earnings was remitted to WestRock and all sources of cash were funded by WestRock prior to May 15, 2016. Off-Balance Sheet Arrangements Ingevity is not a party to any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on Ingevity's financial condition, results of operations or cash flows. Contractual Obligations We enter into various contractual obligations throughout the year. Presented below are the contractual obligations of Ingevity as of December 31, 2017, and the time period in which payments under the obligations are due. Included below are disclosures regarding the amounts due under purchase obligations. A purchase obligation is defined as an agreement to purchase goods or services that is enforceable and legally binding on Ingevity and that specifies all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. We have included in the below disclosure all normal and recurring purchase orders, take-or-pay contracts and supply arrangements as well as other purchase commitments that management believes meet the above definition of a purchase obligation. 50 In millions Contractual obligations(1) Debt maturities Contractual interest (2) Capital lease obligations (3) Operating lease obligations Purchase obligations Pending acquisition (4) Payments due in period Total at December 31, 2017 2018 2019-2020 2021-2022 2023 and beyond $ 375.0 $ 9.4 $ 34.3 138.3 56.9 151.8 315.0 5.1 6.1 19.1 148.7 315.0 46.9 19.1 12.2 22.9 3.1 — $ 318.7 $ 10.1 12.2 8.5 — — — — 107.8 6.4 — — Total $ 1,071.3 $ 503.4 $ 104.2 $ 349.5 $ 114.2 _______________ (1) Amounts included in this Contractual Obligations table do not include any obligations associated the $300.0 million senior unsecured notes issued on January 24, 2018.

The rate assumed for the variable interest component of the contractual interest obligation was the rate in effect at December 31, 2017. Variable rates are determined by the market and will fluctuate over time. (3) Amounts include the interest payments under the capital lease as well as the principal payment due in 2027. (4) Amounts include the purchase price for the pending acquisition of GP's Pine Chemical Business. The closing is subject to regulatory clearance and other customary closing conditions, which are currently ongoing. See "Recent Developments - Pending Georgia Pacific's Pine Chemical Business Acquisition" included within Part II. Item 7 of this Form 10-K for more information. New Accounting Guidance Refer to the Note 4 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 Our principal accounting policies are described in Note 3 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of some assets and liabilities and, in some instances, the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Management believes the accounting policies discussed below represent those accounting policies requiring the exercise of judgment where a different set of judgments could result in the greatest changes to reported results. Revenue recognition: We recognize revenues at the point when title and the risk of ownership passes to the customer. Substantially all of Ingevity’s revenues are generated through product sales and shipping terms generally indicate when title and the risk of ownership have passed. Revenue is recognized at shipment for sales where shipping terms are FOB (free on board) shipping point unless risk of loss is maintained under freight terms. For sales where shipping terms are FOB destination, revenue is recognized when the goods are received by the customer. We provide allowances for estimated returns and other customer credits such as discounts and volume rebates, when the revenue is recognized, based on historical experience, current trends and any notification of pending returns. Amounts billed for sales and use taxes, value-added taxes and certain excise and other specific transactional taxes imposed on revenue-producing transactions are presented on a net basis and excluded from sales in the consolidated income statements. We record a liability until remitted to the respective taxing authority. Accounts receivable and allowance for doubtful accounts: Accounts 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 doubtful accounts is our best estimate of the amount of probable loss in the existing accounts receivable. We determine the allowance 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 51 individually for collectability. Account balances are charged off against the allowance when it is probable that the receivable will not be recovered. Accounts receivables have been reduced by an allowance for doubtful accounts of $0.4 million and $0.3 million at December 31, 2017 and 2016, 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. We had accounts receivable from our largest customer of $16.4 million and $15.5 million as of December 31, 2017 and 2016, respectively. Sales to this customer, which are included in our Performance Chemicals segment, were 8 percent, 9 percent and 11 percent of total net sales for the years ended December 31, 2017, 2016 and 2015, respectively. No other customers individually accounted for greater than 10 percent of Ingevity’s consolidated net sales. Impairment of long-lived assets: We periodically evaluate whether current events or circumstances indicate that the carrying value of 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, 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. Income taxes: The Company is subject to income taxes in the United States and numerous foreign jurisdictions, including China. 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 upon 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. Please see Note 17 to the Consolidated Financial Statements included within Part II. Item 8 of this Form 10-K for more information. The Company recognizes income tax positions that are more likely than not to be realized and accrues 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 16 percent of our net sales in 2017. Ingevity's significant operations outside the United States have designated the local currency as their functional currency. The primary currencies for which we have exchange rate exposure are the U.S. dollar versus the euro, the Japanese yen 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. During 2017, we began hedging this foreign currency exchange rate risk. Foreign exchange forward contracts are used to hedge firm and highly anticipated foreign currency cash flows. The U.S. dollar versus the euro is our most significant foreign currency exposure. A hypothetical 10 percent change in the average euro to U.S. dollar exchange rate during the year ended December 31, 2017, would have changed our net sales and income before income taxes by approximately $8 million or one percent and $4 million or two percent, respectively. Concentration of credit risk 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 52 of credit, guarantees or collateral. We had accounts receivable from our largest customer of $16.4 million and $15.5 million as of December 31, 2017 and 2016, respectively. Sales to this customer, which are included in our Performance Chemicals segment, were 8 percent, 9 percent and 11 percent of total net sales for the years ended December 31, 2017, 2016 and 2015, respectively. No other customers individually accounted for greater than 10 percent of Ingevity’s consolidated net sales. Commodity price risk A portion of our manufacturing costs include 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 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 is approximately 13 percent of all of our cost of sales and 35 percent of our raw materials purchases for the year ended December 31, 2017. Pricing for CTO is subject to particular pricing pressures by reasons of the limited supply elasticity of the product and competing demands for its use, both of which drive pressure on price. Our gross profit and margins could be adversely affected by changes in the cost of CTO if we are unable to pass the increases on to our customers. CTO is a thinly traded commodity with pricing commonly established for periods ranging from one quarter to one year periods of time. We try to protect against such pricing fluctuations through various business strategies. Based on average pricing during the year ended December 31, 2017, a hypothetical unhedged, unfavorable 10 percent change in the market price for CTO would have resulted in additional costs of sales of approximately $7 million or one percent, which we may or may not have been able to pass on to our customers. Natural gas price risk Natural gas is our largest form of energy purchases constituting approximately two percent of our cost of goods sold for the year ended December 31, 2017. 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. In December 2017, we entered into certain derivative financial instruments in order to mitigate expected fluctuations in market prices and the volatility to earnings and cash flow resulting from changes to pricing of natural gas purchases. Refer to the Note 5 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, 2017, a hypothetical, unhedged 10 percent increase in natural gas pricing would have resulted in an increase to cost of sales of approximately $1.4 million. As of December 31, 2017, open commodity contracts hedge forecasted transactions until December 31, 2018. The fair value of the outstanding designated natural gas commodity hedge contracts as of December 31, 2017 was less than $0.1 million. The net fair value of swap contracts and zero cost collar option contracts was less than $0.1 million and zero as of December 31, 2017 and 2016, respectively. The potential increase in fair value from a 10% favorable change in the underlying commodity prices, in U.S. dollar terms, would be $0.5 million and zero at December 31, 2017 and 2016, respectively. The potential decrease in fair value from a 10% adverse change in the underlying commodity prices, in U.S. dollar terms, would be $0.4 million and zero at December 31, 2017 and 2016, respectively. Interest Rate Risk As of December 31, 2017, approximately $375 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. A 100 basis point increase in the variable interest rate component of our borrowings would increase our annual interest expense by approximately $4 million or 22 percent. 53 ITEM 8.

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 generally accepted accounting principles 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, 2017, based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control- Integrated Framework (2013). Based on its assessment and those criteria, management concluded that the Company maintained effective internal control over financial reporting as of December 31, 2017. PricewaterhouseCoopers LLP, an independent registered public accounting firm, has audited the effectiveness of the Company's internal control over financial reporting as of December 31, 2017, as stated in their report, which is presented on the following page. Date: February 28, 2018 By: /S/ D. MICHAEL WILSON D. Michael Wilson /S/ JOHN C. FORTSON John C. Fortson President and Chief Executive Officer Executive Vice President and Chief Financial Officer 55 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 as of December 31, 2017 and December 31, 2016, and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2017, 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, 2017, 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, 2017 and December 31, 2016, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2017 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, 2017, 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. 56 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. /s/ PricewaterhouseCoopers LLP Charlotte, North Carolina February 28, 2018 We have served as the Company’s auditor since 2015. 57 INGEVITY CORPORATION

We provide innovative solutions to meet our customers’ unique and demanding requirements through proprietary formulated products. We report in two business segments, Performance Materials and Performance Chemicals. Our Performance Materials segment consists of our automotive technologies and process purifications product families. Automotive technologies produces automotive carbon products used in gasoline vapor emission control systems in cars, trucks, motorcycles and boats. Process purifications produces a number of activated carbon products for food, water, beverage and chemical purification applications. Our Performance Chemicals segment consists of our pavement technologies, oilfield technologies and industrial specialties product families. Ingevity’s Performance Chemical products serve as critical inputs used in a variety of high performance applications, including asphalt paving, oil exploration and production, printing inks, adhesives, agrochemicals, and lubricants. Separation and Distribution On May 15, 2016 (the "Distribution Date"), we completed the previously announced separation of Ingevity from WestRock Company (“WestRock”) (herein referred to as the "Separation"). The Separation was completed pursuant to a Separation and Distribution Agreement and other agreements with WestRock related to the Separation, including an Employee Matters Agreement ("EMA"), a Tax Matters Agreement ("TMA"), a Transition Services Agreement and an Intellectual Property Agreement (collectively, the "Separation Agreements"), each of which was filed as an exhibit to our Current Report on Form 8-K, filed with the Securities and Exchange Commission on May 16, 2016. The Separation was completed by way of a distribution of all of the then outstanding shares of common stock of Ingevity through a dividend in kind of Ingevity's common stock (par value $0.01) to holders of record of WestRock common stock (par value $0.01) as of the close of business of May 4, 2016 (the "Record Date"). Ingevity's common stock began "regular-way" trading on the New York Stock Exchange ("NYSE") on May 16, 2016 under the symbol "NGVT". Note 2: Basis of Consolidation and Presentation Ingevity did not operate as a separate, stand-alone entity for the full period covered by these Consolidated Financial Statements. Our consolidated balance sheet as of December 31, 2017 and 2016, respectively, our consolidated statement of operations and consolidated statement of comprehensive income (loss) for the year ended December 31, 2017, as well as our consolidated statement of cash flows for the year ended December 31, 2017 consists of the consolidated balances of Ingevity as prepared on a stand-alone basis. Our consolidated statements of operations and consolidated statements of comprehensive income (loss) for the years ended December 31, 2016 and 2015, respectively, as well as our consolidated statements of cash flows for the years ended December 31, 2016 and 2015, respectively, have been prepared on a “carve out” basis for the periods and dates prior to the spin-off on May 15, 2016. Prior to the Separation, Ingevity's operations were included in WestRock's financial results and were comprised of certain WestRock wholly owned legal entities for which Ingevity was the sole business and components of legal entities in which Ingevity operated in conjunction with other WestRock businesses. For periods prior to May 15, 2016, the accompanying Consolidated Financial Statements were prepared from WestRock's historical accounting records and are presented on a stand-alone basis as if the business operations had been conducted independently from WestRock. Prior to May 15, 2016, WestRock's net investments in these operations is shown in lieu of Ingevity stockholder's equity in the Consolidated Financial Statements. The Consolidated Financial Statements include the historical operations, assets and liabilities of the legal entities that are considered to comprise the Ingevity business. In all periods presented within these Consolidated Financial Statements all intercompany accounts and transactions have been eliminated. The Consolidated Financial Statements include the accounts of Ingevity and subsidiaries in which a controlling interest is maintained. If Ingevity's ownership is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. In all periods presented within the Consolidated Financial Statements, our noncontrolling interest represents the 30 percent ownership interest held by a third party U.S. based company in our consolidated Purification Cellutions LLC legal entity. Purification Cellutions LLC is the legal entity that owns technology associated with, and manufactures, our structured honeycomb products within our Performance Materials segment. 65 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 For purposes of these Consolidated Financial Statements, the term “WestRock” herein refers to the legacy operations of MeadWestvaco Corporation (“MWV”) and its subsidiaries prior to the July 1, 2015 merger of MWV and Rock-Tenn Company ("Rock-Tenn") (the "Merger") and the combined operations of Rock-Tenn and MWV subsequent to the Merger. References to Ingevity’s historical business and operations refer to the business and operations of the Specialty Chemicals Business of WestRock, or prior to the Merger, MWV, that were transferred to Ingevity in connection with the Separation. All of the allocations and estimates in the Consolidated Financial Statements prior to May 15, 2016 are based on assumptions that management believes are reasonable. However, the Consolidated Financial Statements included herein may not be indicative of the financial position, results of operations and cash flows of Ingevity in the future or if Ingevity had been a separate, stand-alone entity during the periods presented. Note 3: Summary of significant accounting policies Noncontrolling interests: When our ownership in a consolidated legal entity is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. Our noncontrolling interests for the periods ended December 31, 2017, 2016 and 2015, represents the 30 percent ownership interest held by a third party U.S. based company in our consolidated Purification Cellutions LLC ("PurCell") legal entity. PurCell is the legal entity that owns technology associated with, and manufactures, our structured honeycomb scrubber products within our Performance Materials segment. Net income (loss) attributable to noncontrolling interest as presented on our consolidated statement of operations also represents the 30 percent of the pre-tax earnings from PurCell owned by the third party. PurCell is a limited liability company which is treated as a "pass- through" entity for tax purposes. Although we consolidated 100 percent of PurCell, only 70 percent of PurCell's earnings are included in the calculation of Ingevity's provision for income taxes as presented on the consolidated statement of operations. 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. Actual results are likely to differ from those estimates, but we do not believe such differences will materially affect our financial position, results of operations or cash flows. Translation of foreign currencies: The local currency is the functional currency for all of Ingevity’s significant operations outside the United States (“U.S.”). The assets and liabilities of Ingevity's foreign subsidiaries are translated into U.S. dollars using period-end exchange rates, and adjustments resulting from these financial statement translations are included in accumulated other comprehensive income in the consolidated balance sheets. Revenues and expenses are translated at average rates prevailing during each period. Cash equivalents: Highly liquid securities with an original maturity of three months or less are considered to be cash equivalents. Accounts receivable and allowance for doubtful accounts: Accounts receivable, net on the consolidated balance sheets are comprised of trade receivable less allowances for doubtful accounts. 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 doubtful accounts is our best estimate of the amount of probable loss in the existing accounts receivable. We determine the allowance 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 doubtful accounts at December 31, 2017 and 2016, were $0.4 million and $0.3 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. We had accounts receivable from our largest customer of $16.4 million and $15.5 million as of December 31, 2017 and 2016, respectively. Sales to this customer, which are included in the Performance Chemicals segment, were 8 percent, 9 percent, and 11 percent of total net sales for the years ended December 31, 2017, 2016 and 2015, respectively. No other customers individually accounted for greater than 10 percent of the Ingevity's consolidated net sales. Inventories, net: Inventories are valued at net realizable value. Cost is determined using the last-in, first-out method (“LIFO”) for substantially all raw materials, finished goods and production materials of U.S. manufacturing operations. Cost of all other inventories, including stores and supplies inventories and inventories of non-U.S. manufacturing operations, is determined by the first-in, first-out ("FIFO") or average cost methods. As of December 31, 2017, approximately 21 percent, 13 percent and 66 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 66 percent of our inventories were accounted for under the FIFO, average cost, and LIFO methods, respectively. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead. 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 in cost of sales. 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; general costs of maintenance and repairs are charged to expense. 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 “Other 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 in 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 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 the detail behind the useful lives and proportion of our machinery and equipment (“M&E”) in each useful life category. Percent of M&E Cost Depreciable Life in Years Types of Assets 59 12 8 18 3 20 15 Production vessels and kilns, storage tanks, piping Control systems, instrumentation, metering equipment 25 to 30 Blending equipment, storage tanks, piping, shipping equipment and platforms, safety equipment 5 to 10 Production control system equipment and hardware, laboratory testing equipment 40 Machinery & equipment support structures and foundations 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, 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 review the recorded value of goodwill at least annually 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. If goodwill is required to be tested for impairment, a two-step process is utilized. The first step is to identify a potential impairment and the second step is to measure the amount of the impairment loss, if any. The second step is not necessary unless an impairment indicator is identified in step one. Goodwill is deemed to be impaired after step two if the carrying amount of a reporting unit’s goodwill exceeds its estimated fair value. Upon the adoption of ASU 2017-04, as further described in Note 4, "step two" of the two-step process will be eliminated, see more information on the impact of adopting this new accounting standard in Note 4. The fair value of each reporting unit is estimated primarily using an income approach, specifically the discounted cash flow method. The following assumptions are key to the income approach: 1). business projections; 2). growth rates; 3). discount rates; 4). tax rates. Other intangible assets are comprised of finite-lived intangible assets consisting primarily of brand, representing trademarks, trade names and know-how, customer contracts and relationships. Other intangible assets are amortized over their estimated useful lives which range from 5 to 20 years. See Note 8 for additional information. 67 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 Capitalized software: Capitalized software for internal use is included in "Other assets" on the consolidated balance sheets. Amount 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 1 to 7 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. Environmental and legal liabilities: Environmental expenditures that increase useful lives of assets are capitalized, while other environmental expenditures are expensed. Liabilities are recorded when remedial efforts are probable and the costs can be reasonably estimated. We recognize a liability for other legal contingencies when a loss is probable and reasonably estimable. Liabilities recorded for claims are limited to pending cases based on Ingevity’s historical experience, consultation with outside counsel and consultation with an actuarial specialist concerning the feasibility of reasonably estimating liabilities associated with claims that may arise in the future. We recognized insurance recoveries when collection is reasonably assured. Third-party fees for legal services are expensed as incurred. Revenue recognition: We recognize revenues at the point when title and the risk of ownership passes to the customer. Substantially all of Ingevity’s revenues are generated through product sales and shipping terms generally indicate when title and the risk of ownership have passed. Revenue is recognized at shipment for sales where shipping terms are FOB (free on board) shipping point unless risk of loss is maintained under freight terms. For sales where shipping terms are FOB destination, revenue is recognized when the goods are received by the customer. We provide allowances for estimated returns and other customer credits such as discounts and volume rebates, when the revenue is recognized, based on historical experience, current trends and any notification of pending returns. Amounts billed for sales and use taxes, value-added taxes and certain excise and other specific transactional taxes imposed on revenue-producing transactions are presented on a net basis and excluded from sales in the consolidated income statements. We record a liability until remitted to the respective taxing authority. Shipping and handling costs: Shipping and handling costs are classified as a component of cost of sales. Amounts billed to a customer in a sales transaction related to shipping and handling are classified as revenue. Cost of sales: Costs primarily consists 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 also recorded to cost of sales. 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: Cost are expensed as incurred and primarily include employee compensation, technical equipment costs and material testing and innovation related expenses. Royalty expense: Our Performance Materials and Performance Chemicals segments have licensing agreements with third parties requiring us to pay royalties for certain technologies we use in the manufacturing our of products. Royalty expense is recognized as incurred and recorded to "Cost of sales" on our consolidated statements of operations. Income taxes: The Company is subject to income taxes in the U.S. and numerous foreign jurisdictions, including China. 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 upon 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. Please see Note 17 for more information. The Company recognizes income tax positions that are more likely than not to be realized and accrues interest related to unrecognized income tax positions, which is included as a component of the income tax provision on the consolidated statements of operations. 68 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 Ingevity’s pre-Separation activity in the U.S. will be reported in WestRock’s U.S. consolidated income tax return and certain foreign activity will be reported in WestRock tax paying entities in those jurisdictions. Under the Tax Matters Agreement of the Separation, WestRock is responsible for the income tax liabilities associated with all U.S. operations prior to Separation and for the historic operations of certain foreign legal entities retained by WestRock after the Separation. For periods prior to the Separation, the income tax provision included in the Consolidated Financial Statements, related to domestic and certain foreign operations, was calculated on a separate return basis, as if Ingevity was a separate taxpayer and the resulting current tax receivable or liability, including any liabilities related to uncertain tax positions, was settled with WestRock through equity at Separation. In other foreign taxing jurisdictions, the operations of Ingevity were always conducted in discrete legal entities, each of which files separate tax returns, and all resulting income tax assets and liabilities, including any liabilities related to uncertain tax positions, are reflected in the consolidated balance sheets of Ingevity. Pension and postretirement benefits: Prior to the Separation, the employees of Ingevity were participants in various defined benefit pension and postretirement benefit plans (“the Plans”) sponsored by WestRock and the related assets and liabilities were combined with those related to other WestRock businesses. Expense allocated under the Plans was reported within Cost of sales and Selling, general and administrative expenses in the consolidated statements of operation. We considered the Plans to be part of a multi-employer plan with the other businesses of WestRock. In conjunction with the Separation, the employees of Ingevity stopped participating in WestRock pension and post- retirement benefit plans. We assumed certain domestic and international pension and other post-retirement benefit obligations from WestRock on the date of Separation. We established new qualified and non-qualified benefit plans to continue the pension and postretirement benefits provided to its employees and retirees based on the obligations assumed from WestRock. The expense related to the current employees of Ingevity as well as the expense related to retirees of Ingevity are included in 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, 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. See Note 13 for additional information. Share-based compensation: We recognize compensation expense in 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 ("RSU"s), non-employee director deferred stock units ("DSU"s) and performance-based restricted stock units ("PSU"s) is determined using our closing stock price on the day of the grant. Substantially all compensation expense related to share-based awards is recorded as a component of Selling, general and administrative expenses in the Consolidated Statements of Operations. See Note 10 for additional information. Operating segments: Ingevity’s operating segments are Performance Materials and Performance Chemicals. 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. Ingevity’s chief operating decision maker evaluates the business at the segment level when making decisions about allocating resources and assessing performance of Ingevity as a whole. We evaluate sales in a format consistent with our reportable segments: (1) Performance Materials, which includes wood-based, chemically activated carbon products and (2) Performance Chemicals, which includes specialty pine-based chemical co-products derived from the kraft pulping process. Each segment operates as a portfolio of various end uses for the relevant raw material used in that segment. Business decisions are made and performance is generally measured based upon the total mix of end uses each raw material is being directed at in the segment. See Note 19 for additional information. Derivative financial instruments: We mitigate certain financial exposures, including currency risk and commodity price exposures, through a controlled program of risk management that includes the use of derivative financial instruments. We formally document all relationships between the derivative financial instrument and hedged item, as well as the risk management objective and strategy for undertaking various hedge transactions. This process includes relating derivative financial instruments that are 69 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 designated as cash flow hedges to specific forecasted 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. On the date the derivative financial instrument is entered into, we generally designate the derivative as a hedge of the variability of cash flows to be received or paid related to a forecasted transaction (cash flow hedge). 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 designated and qualify as a cash flow hedge are recorded on the 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 in 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 statement of operations when the forecasted transaction occurs. Designated commodity cash flow hedges gains or losses recorded in AOCI are recognized in "Cost of sales" on the consolidated statements of operations when the inventory is sold. See Note 5 for more information regarding our derivative financial instruments. As further described in Note 4, in the fourth quarter of 2017 we adopted ASU 2017-12, the impact of adoption was not material to our Consolidated Financial Statement and related disclosures. Relationship with WestRock: For periods prior to May 15, 2016, these Consolidated Financial Statements include allocated expenses associated with centralized WestRock support functions including legal, accounting, tax, treasury, internal audit, information technology, human resources and other services. The costs associated with these functions generally include all payroll and benefit costs as well as related overhead costs. For periods prior to May 15, 2016, these Consolidated Financial Statements also include allocated costs associated with WestRock’s office facilities, corporate insurance coverage and medical, pension, post- retirement and other health plan costs attributed to Ingevity’s employees participating in WestRock’s sponsored plans. Allocations are generally based on a number of utilization measures including employee count and proportionate effort. In situations in which determinations based on utilization are impracticable, WestRock and Ingevity used other methods and criteria such as net sales which are believed to result in reasonable estimates of costs attributable to Ingevity. Such allocated expenses are components of net income in the consolidated statement of operations and are therefore included as a component of net cash provided by (or used in) operating activities in the consolidated statement of cash flows. All such amounts have been assumed to have been immediately settled by Ingevity to WestRock in the period in which the costs were recorded in the Consolidated Financial Statements. We believe the related-party allocations included in these Consolidated Financial Statements for periods prior to the Separation have been made on a reasonable basis. However, these Consolidated Financial Statements may not necessarily be indicative of the results of operations that would have been obtained if Ingevity had operated as a separate entity during the periods presented prior to May 15, 2016. Actual costs that may have been incurred if Ingevity had been a stand-alone business would depend on a number of factors, including organizational structure and what functions were outsourced or performed by employees, as well as strategic decisions made in areas such as information technology and infrastructure. Consequently, Ingevity’s future earnings while operated as an independent business could include items of income and expense that are materially different from what is included in the consolidated statements of operations prior to the Separation. Accordingly, the Consolidated Financial Statements for the periods presented prior to the Separation are not necessarily indicative of Ingevity’s future results of operations, financial position and cash flows. Treasury Stock: We record shares of common stock repurchased at cost as treasury stock, resulting in a reduction of stockholders’ equity in 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 the related capital in excess of par value of common stock. Reclassifications: Certain prior year amounts have been reclassified to conform with current year's presentation. Note 4: New accounting guidance In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-02 "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassifications of Certain Tax Effects from AOCI." 70 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 This ASU provides for the reclassification of the effect of remeasuring deferred tax balances related to items within accumulated other comprehensive income to retained earnings resulting from the provisions of the December 22, 2017, U.S. Tax Cuts and Jobs Act (the "U.S. Tax Reform"). We early adopted this new ASU in the fourth quarter of 2017 and as a result, we reclassified $0.3 million from AOCI to retained earnings. In August 2017, the FASB issued ASU 2017-12 "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" that amends the hedge accounting recognition and presentation requirements under hedge accounting. The new standard will make more financial and non-financial hedging strategies eligible for hedge accounting, amends the presentation and disclosure requirements, and simplifies how companies assess effectiveness. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those years, and early adoption is permitted. We early adopted this new ASU during the fourth quarter of 2017. The impact of adoption did not have a material effect on our Consolidated Financial Statements and related disclosures. In May 2017, the FASB issued ASU No. 2017-09 "Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting," which provided clarity on which changes to the terms or conditions of share-based payment awards require an entity to apply the modification accounting provisions required in Topic 718. We have early adopted this new standard during our second quarter of 2017. The impact of adoption did not have a material effect on our Consolidated Financial Statements and related disclosures. In March 2017, the FASB issued ASU 2017-07 "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendment in this new standard requires the service cost component to be presented separate from the other components of net benefit cost. Service cost will be presented with other employee compensation costs within operations. The other components of net benefit cost, such as interest cost, amortization of prior service cost, and gains or losses, are required to be separately presented outside of operations, if income or loss from operations is presented. Of the components of net periodic benefit cost, only the service cost component will be eligible for asset capitalization. We have early adopted this new standard during our first quarter of 2017 on a retrospective basis. The adoption of this new guidance had no impact on our Consolidated Financial Statements and related disclosures. In January 2017, the FASB issued ASU 2017-04 "Simplifying the Test for Goodwill Impairment (Topic 350)," which amends and simplifies the accounting standard for goodwill impairment. The new standard removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. The new standard is effective for annual and any interim impairment tests for periods beginning after December 15, 2019, and early adoption is permitted for any impairment tests performed after January 1, 2017. The Company will adopt this standard on January 1, 2018. This new guidance will not have a material impact on our Consolidated Financial Statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805), Clarifying the Definition of a Business." The new guidance narrows the existing definition of a business and provides a framework for evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities (collectively, the "set") is not a business. To be considered a business, the set would need to include an input and a substantive process that together significantly contribute to the ability to create outputs, as defined by the ASU. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods, and should be applied prospectively. We will adopt this standard on January 1, 2018 and will apply it prospectively to all applicable transactions after the adoption date. We have evaluated this new guidance and have determined that its adoption will not change our conclusions regarding the pending Georgia Pacific's Pine Chemical Business acquisition, refer to Note 16 for more information. In November 2016, the FASB issued new guidance on restricted cash in ASU 2016-18 "Statement of Cash Flows (Topic 230): Restricted Cash." The new guidance clarifies the guidance on the cash flow classification and presentation of changes in restricted cash or restricted cash equivalents. Amounts generally described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flow. We have early adopted this new standard during our first quarter of 2017. The impact of adoption did not have a material effect on our Consolidated Financial Statements and related disclosures. In October 2016, the FASB issued new guidance on tax accounting for intra-entity transfers of assets in ASU 2016-16 "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." The new guidance requires that entities 71 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, rather than when the asset is sold to an outside party. We have early adopted this new standard during our first quarter of 2017. The impact of adoption did not have a material effect on our Consolidated Financial Statements and related disclosures. In August 2016, the FASB issued final amendments to clarify how entities should classify certain cash receipts and cash payments in ASU 2016-15 "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments." The new guidance clarifies the classification on the statement of cash flows of certain cash receipts and disbursements such as distributions received from equity method investees, proceeds from settlement of insurance claims, and proceeds from the settlement of corporate-owned life insurance policies. The new standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those years. This new guidance will not have a material impact on our Consolidated Financial Statements and related disclosures. In February 2016, the FASB issued ASU 2016-02 "Leases." Under the new guidance, lessees will be required to recognize for all leases (with the exception of short-term leases) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are in the process of evaluating the impact of this guidance on our Consolidated Financial Statements and related disclosures, including identifying and analyzing all contracts that contain a lease. As a lessee, the majority of our leases under existing guidance are classified as operating leases and therefore not recorded on the balance sheet but are recorded in the statement of earnings as expense as incurred. Upon adoption of the new guidance, we may be required to record the vast majority of these operating leases on the balance sheet as a right-of-use asset and a lease liability. The timing of expense recognition and classification in the statement of earnings could change based on the classification of leases as either operating or financing; however, we have not completed our evaluation to determine to what extent. In July 2015, the FASB issued ASU 2015-11 "Simplifying the Measurement of Inventory." This new standard changes the criteria by which to measure inventory. Prior to the issuance of this new standard, inventory was measured at the lower of cost or market value. This required three separate data points in order to measure inventory. The three data points were cost, market with a ceiling of net realizable value and market with a floor of net realizable value less a normal profit margin. This amendment eliminates the two data points defining "market" and replaces them with one, net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This amendment does not impact inventory measured using last-in, first-out. We adopted this new standard during our first quarter of 2017. The impact of adoption did not have a material effect on our Consolidated Financial Statements and related disclosures. In May 2014, the FASB issued ASU 2014-09 which is codified in ASC 606 “Revenue from Contracts with Customers” and supersedes both the revenue recognition requirement to ASC 605 “Revenue Recognition” and most industry-specific guidance ("ASC 606"). The core principle of ASC 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity must also disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative information about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. In 2016 and 2017, the FASB issued several ASUs that provided additional clarity on numerous topics as well as providing technical corrections to the original ASU 2014-09. The new standard will be effective for Ingevity in the first quarter of 2018 and can be applied using a modified retrospective or full retrospective method. We have decided to adopt this new standard using the modified retrospective method, which results in the recognition of the cumulative effect of initially applying the new standard as an adjustment to the opening balance of equity. We have determined that the adoption of this new standard will not have a material impact to our Consolidated Financial Statements, financial condition or liquidity. We do however expect to have enhanced disclosures related to accounting policies, including disclosure of contract assets, contract liabilities as well as disaggregated revenue streams, which we expect to be similar to product line revenue disclosure included in Note 19. All other issued but not yet effective accounting pronouncements are not expected to have a material impact on our Consolidated Financial Statements. 72 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 Note 5: Financial Instruments, Risk Management and Fair Value Measurements Financial Instruments and Risk Management Ingevity’s operations are exposed to market risks, such as changes in foreign currency exchange rates and commodity prices due to transactions denominated in a variety of foreign currencies and purchases of certain commoditized raw materials and inputs. Changes in these rates and prices may have an impact on Ingevity’s future cash flow and earnings. To mitigate these market risks and their effects, 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 reported on a net basis by counterparty, to the extent governed by master netting agreements, in the consolidated balance sheets. Due to our proactive mitigation of these potential credit risk we anticipate performance by our counterparties to these contracts and therefore no material loss is expected. 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. We began our foreign currency exchange risk hedging program in July 2017 and therefore prior to this date we had no derivative financial instruments designated to foreign currency exchange risk. As of December 31, 2017 we had no forward currency exchange contracts or zero cost collar option contracts outstanding. Commodity Price Risk Management Certain energy sources used by the Company, are subject to price volatility caused by weather, supply and demand conditions, economic variables and other unpredictable factors. This volatility is primarily related to the market pricing of natural gas. To mitigate expected fluctuations in market prices and the volatility to earnings and cash flow resulting from changes to pricing of natural gas purchases, from time to time, we will enter into swap contracts and zero cost collar option contracts and designate these contracts as cash flow hedges. We began our commodity price risk hedging program in December 2017 and therefore prior to this date we had no derivative financial instruments designated to hedge commodity price risk. As of December 31, 2017, we had 1.4 million and 1.4 million mmBTUS (millions of British Thermal Units) in aggregate notional volume of outstanding natural gas commodity swap contracts and zero cost collar option contracts, respectively, designated as cash flow hedges. As of December 31, 2017, open commodity contracts hedge forecasted transactions until December 31, 2018. The fair value of the outstanding designated natural gas commodity hedge contracts as of December 31, 2017 was less than $0.1 million. 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. 73 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 The following information is presented for assets and liabilities that are recorded in the consolidated balance sheets at fair value measured on a recurring basis. There were no assets recorded at fair value measured on a recurring basis as of December 31, 2016. There were no significant transfers of assets and liabilities that are recorded at fair value between Level 1 and Level 2 during the period reported.

This amount represents an amount due to WestRock associated with WestRock equity awards held by Ingevity employees post Separation. In accordance with the Employee Matters Agreement between Ingevity and WestRock entered into in connection with the Separation, we are required to reimburse WestRock the fair market value of awards on the day Ingevity employees exercise their awards. The expense recognized during the years ended December 31, 2017 and 2016 was $0.3 million and $1.6 million, respectively. At December 31, 2017 and 2016, the book value of capital lease obligations was $80.0 million and $80.0 million, respectively, and the fair value was $92.9 million and $91.6 million, respectively. The fair value of our capital lease obligations is based on the period-end quoted market prices for the obligations, using Level 1 inputs. The carrying amount of our long-term debt was $365.6 million and $404.4 million as of December 31, 2017 and 2016, respectively. The carrying value is a reasonable estimate of the fair value of our outstanding debt as our outstanding debt is variable interest rate debt. At December 31, 2017 and 2016, the book value of our restricted investment was $71.3 million and $69.7 million, respectively, and the fair value was $69.6 million and $67.1 million, respectively, based on Level 1 inputs. The carrying value of our financial instruments: cash and cash equivalents, accounts receivable, other receivables, other payables and accrued liabilities approximate their fair values due to the short-term nature of these financial instruments. 74 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 Note 6: Inventories, net In millions Raw materials Production materials, stores and supplies Finished and in-process goods Less: excess of cost over LIFO cost $ Subtotal Inventories, net $ December 31, 2017 2016 40.1 13.4 114.3 167.8 (7.8) 160.0 $ $ 50.8 12.0 109.8 172.6 (21.4) 151.2 Approximately 66 percent and 68 percent of Inventories, net at December 31, 2017 and 2016, respectively, are valued using the LIFO method.

Note 9: Debt including Capital Lease Obligations 2018 Senior Notes On January 24, 2018, we issued $300.0 million aggregate principal amount of 4.50 percent senior unsecured notes due 2026 (the “Notes”). The Notes were issued pursuant to an indenture dated as of January 24, 2018 (the “Indenture”), by and among Ingevity, the subsidiary guarantors party thereto and U.S. Bank National Association, as trustee. The Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A and to certain non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). The Notes have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws. 76 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 The net proceeds from the sale of the Notes, after deducting deferred financing fees of $5.6 million were approximately $294.4 million. We intend to use the net proceeds from the sale of the Notes to finance our planned purchase of substantially all the assets primarily used in the pine chemicals business of Georgia-Pacific Chemicals LLC and Georgia-Pacific LLC and for general corporate purposes. Interest payments on the Notes are due semiannually in arrears on February 1st and August 1st of each year, beginning on August 1, 2018, at a rate of 4.50 percent per year. The Notes will mature on February 1, 2026. The Indenture contains certain customary covenants (including covenants limiting Ingevity and our 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 our 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 Indenture could result in the acceleration of the Notes and could cause a cross-default that could result in the acceleration of other indebtedness of Ingevity and our subsidiaries. Revolving Credit and Term Loan Facility Amendment On August 21, 2017, we entered into an Incremental Facility Agreement and Amendment No. 1 (the “Amendment”) to our existing Credit Agreement, dated as of March 7, 2016 (the “Existing Credit Agreement,” and as amended by the Amendment, the “Amended Credit Agreement”). Among other things, the Amendment (i) established incremental term loan commitments in the aggregate principal amount of $75.0 million (the incremental term loans made pursuant thereto, the “Incremental Term Loans”) and (ii) increased the revolving commitments under the Existing Credit Agreement by $150.0 million (the “Incremental Revolving Commitments”). The Amendment also extended the maturity date for the loans and commitments under the Existing Credit Agreement by one year, to May 9, 2022. The Incremental Term Loans have terms identical to those of the Term A Loans under the Existing Credit Agreement (the "Term A Loans"), as modified by the Amended Credit Agreement, and will be treated as a single class with such existing Term A Loans under the Amended Credit Agreement. The Incremental Revolving Commitments have terms identical to those of the Revolving Commitments under the Existing Credit Agreement, as modified by the Amended Credit Agreement, and will be treated as a single class with such existing commitments under the Amended Credit Agreement. Loans under the Amended Credit Agreement, including the Incremental Term Loans and loans with respect to the Incremental Revolving Commitments, bear interest at either (a) an adjusted base rate or (b) an adjusted LIBOR rate, in each case, plus an applicable margin, in the case of base rate loans, ranging between 0.25 percent and 1.00 percent, and in the case of adjusted LIBOR rate loans, ranging between 1.25 percent and 2.00 percent. The applicable margin is based on a total leverage based pricing grid. Fees to revolving lenders under the Amended Credit Agreement, including fees in respect of the Incremental Revolving Commitments, include (i) commitment fees, based on a percentage of the daily unused portions of the facility, ranging from 0.15 percent to 0.30 percent and (ii) customary letter of credit fees. As consideration for the Amendment, the Company paid to each lender under the Existing Credit Agreement a consent fee equal to 0.05 percent of the aggregate principal amount of the commitments and outstanding loans held by such lender immediately prior to the Closing Date. The credit facilities under the Amended Credit Agreement, including the incremental facilities described herein, will mature on May 9, 2022. The Incremental Term Loans and Term A Loans amortize at a rate equal to 0 percent per annum during the first and second years after the initial funding date of May 9, 2016, 5 percent per annum during the third and fourth years after the initial funding date and 10 percent per annum during the fifth and sixth years after the initial funding date, with the balance due at maturity. Fees incurred to secure the Amended Credit Agreement have been deferred and will be amortized over the term of the arrangement. The Amendment also makes certain additional modifications to the terms of the Existing Credit Agreement and related loan documents, including an increase of the maximum consolidated total leverage ratio permitted thereunder from 3.75 to 1.00 to 4.00 to 1.00 (which may be increased to 4.50 to 1.00 under certain circumstances). We were in compliance with all covenants at December 31, 2017. 77 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 As part of the Separation, WestRock required Ingevity to contribute $68.9 million in a trust managed by Bank of New York in order to secure repayment of the capital lease obligation at maturity. The trust, presented as restricted investment on our consolidated balance sheet, purchased long term bonds that mature in 2025 and 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 capital 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; therefore, they are held at their amortized cost. The fair value of the investments within the trust was $69.6 million and $67.1 million as of December 31, 2017 and 2016, respectively (see Note 5 for more information). 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 as interest income and presented within Interest income on our consolidated statement of operations.

Debt maturing within one year is included in "Current maturities of long-term debt" on the consolidated balance sheet. (2) Note 10: Share-based compensation Prior to the Separation, share-based compensation expense was allocated to Ingevity based on the portion of WestRock's incentive share-based compensation program in which Ingevity employees participated. Share-based compensation expense allocated by WestRock to Ingevity was zero, $0.5 million, and $2.3 million for the years ended December 31, 2017, 2016 and 2015, respectively. This allocated share-based compensation expense is included in the overall allocations from WestRock discussed further in Note 12. Equity Incentive Plan Adopted at Separation, the Ingevity Corporation 2016 Omnibus Incentive Plan grants certain corporate officers, key employees and non-employee directors of Ingevity and subsidiaries different forms of benefits, including stock options, RSUs, DSUs and PSUs. The Ingevity Corporation 2016 Omnibus Incentive Plan has maximum shares reserve of 4,000,000 for the grant of equity awards. As of December 31, 2017, 3,265,453 shares under the Ingevity Corporation 2016 Omnibus Incentive Plan are still available for grants, assuming that Ingevity performs at the target performance level in each year of the three-year performance period for PSU awards. Ingevity's Compensation Committee determines the long-term incentive mix, including stock options, RSUs and PSUs, and may authorize new grants annually. 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’ 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% 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 78 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 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% 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. Under the ESPP, a total of 250,000 shares of Ingevity's common stock are reserved and authorized for issuance to participating U.S. employees, as defined by the ESPP, which excludes certain officers of Ingevity. As of December 31, 2017, 243,261 shares under the ESPP are still available for issuance. The initial offering period under the ESPP began on July 1, 2017. During fiscal 2017, there were 6,739 shares purchased under the ESPP at an average price of $48.09. Our share-based compensation expense recognized post Separation associated with Ingevity's incentive plan and the ESPP is included in the table below.

The amount changes based on the fair market value of Ingevity's stock. As of December 31, 2017 and 2016, $2.3 million and $1.4 million, respectively, of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 1.4 and 2.2 years, respectively. 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 of Ingevity’s Board of Directors. 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 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. Compensation expense is recognized over the vesting period and adjusted for the probability of achievement of the performance criteria. 80 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 The following table summarizes Ingevity's RSUs, DSUs and PSUs activity for the period from the Separation through December 31, 2017, as there was no Ingevity stock option activity prior to Separation.

For further information, refer to Note 4. (3) Share Repurchases On February 20, 2017, the Board of Directors authorized the repurchase of up to $100 million of our common stock. The repurchase program does not include a specific timetable or price targets and may be suspended or terminated at any time. Shares 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. During the year ended December 31, 2017, we repurchased 99,000 shares of our common stock at a weighted average cost per share of $66.28. At December 31, 2017, $93.4 million remained unused under our Board-authorized repurchase program. We record shares of common stock repurchased at cost as treasury stock, resulting in a reduction of stockholders’ equity in 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 the related capital in excess of par value of common stock. 82 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 Note 12: Transactions with WestRock and Related Parties For periods prior to May 15, 2016, our Consolidated Financial Statements include allocated expenses associated with centralized WestRock support functions including legal, accounting, tax, treasury, internal audit, information technology, human resources and other services. The costs associated with these functions generally include all payroll and benefit costs as well as related overhead costs. For periods prior to May 15, 2016, our Consolidated Financial Statements also include allocated costs associated with WestRock’s office facilities, corporate insurance coverage and medical, pension, post-retirement and other health plan costs attributed to Ingevity’s employees participating in WestRock’s sponsored plans. Allocations are generally based on a number of utilization measures including employee count and proportionate effort. In situations in which determinations based on utilization are impracticable, WestRock and Ingevity used other methods and criteria such as net sales which are believed to result in reasonable estimates of costs attributable to Ingevity. All such amounts have been assumed to have been immediately settled by Ingevity to WestRock in the period in which the costs were recorded in the Consolidated Financial Statements. Such amounts are included in net cash provided by operating activities in the consolidated statements of cash flows. We believe the related-party allocations for periods included in our Consolidated Financial Statements for periods prior to May 15, 2016 have been made on a reasonable basis. However, our Consolidated Financial Statements may not necessarily be indicative of the results of operations that would have been obtained if Ingevity had operated as a separate entity during the periods presented. Actual costs that may have been incurred if Ingevity had been a stand-alone business would depend on a number of factors, including organizational structure and what functions were outsourced or performed by employees, as well as strategic decisions made in areas such as information technology and infrastructure. Consequently, Ingevity’s future earnings may include items of income and expense that are materially different from what is included in our consolidated statements of operations for periods prior to May 15, 2016. Accordingly, our Consolidated Financial Statements for the periods presented are not necessarily indicative of Ingevity’s future results of operations, financial position and cash flows. The consolidated statements of operations prior to May 15, 2016, include allocations from WestRock as summarized below: In millions Cost of sales Selling, general and administrative expenses Interest expense, net Total allocated cost (1) Years Ended December 31, 2017 2016 2015 $ $ — $ — — — $ 5.7 6.5 7.2 19.4 $ $ 10.3 17.3 13.5 41.1 _______________ (1) Allocated costs represent costs necessary to support Ingevity's operations which include governance and corporate functions such as information technology, accounting, human resources, accounts payable and other direct services including the interest on WestRock debt incurred to provide such services. Prior to the Separation on May 15, 2016, we purchased certain raw materials from WestRock that were included in cost of sales. Purchases for the year ended December 31, 2016 and 2015 were $20.1 million and $35.3 million, respectively. Subsequent to May 15, 2016, Ingevity was no longer a related-party of WestRock. Accordingly, beginning May 16, 2016, sales to WestRock businesses are reflected in net sales in our consolidated statement of operations. Purchases of products from WestRock businesses are reflected as inventory in our consolidated balance sheet and prior to payment reflected as accounts payable in our consolidated balance sheet. Our ongoing relationship with WestRock is governed by the Separation Agreements including the long-term supply agreement for crude tall oil ("CTO"). Under this agreement, based on WestRock’s current output, we currently expect to source approximately 45% to 55% of our CTO requirements for the maximum operating rates of our two Performance Chemicals' facilities. As further described in Note 1, the Separation Agreements govern the relationship among Ingevity and WestRock following the Separation and provide for the allocation of various assets, liabilities, rights and obligations and include arrangements for transition services to be provided by WestRock to Ingevity. In accordance with the Separation Agreements at the Separation we recorded a payable to WestRock in the amount of $16.5 million primarily representing certain trade liabilities previously classified as related-party and included within net parent investment in the consolidated balance sheet. This amount has since been paid to WestRock. 83 Index Note 13: Retirement Plans Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 Prior to the Separation, WestRock offered various long-term benefits to its employees, including Ingevity employees. In these cases, the participation of our employees in these plans is reflected in the Consolidated Financial Statements as though Ingevity participated in a multi-employer plan with the other businesses of WestRock. For periods prior to the Separation, assets and liabilities of such plans were retained by WestRock. Net periodic benefit costs allocated to Ingevity associated with these pension plans, prior to the Separation, for the years ended December 31, 2016 and 2015 were $3.2 million and $7.8 million, respectively. This allocated net periodic benefit cost is included in the overall allocations from WestRock, discussed further in Note 12. The adoption of ASU 2017-07, as further discussed in Note 4, had no impact on these allocated balances. Defined Contribution Plans U.S. Ingevity employees ceased participating in the WestRock 401(k) plan on December 31, 2015 preceding the Separation. Effective January 1, 2016, the Ingevity Corporation Retirement Savings Plan ("Plan") was established. The Plan is a qualified salary-reduction plan under Section 401(k) of the U.S. Internal Revenue Code. Eligible U.S. employees may participate 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 union eligible 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. U.S. salaried employees who were no longer eligible to participate in the WestRock defined benefit pension plan, as of the date of Separation, were provided an enhanced contribution into the Plan. The enhanced benefits consist of a transition contribution of four or ten percent of the employee’s eligible compensation for employees who were grandfathered in the WestRock cash balance and final average pay pension plan, respectively. The transition contributions will continue to December 31, 2020, unless the grandfathered employee terminates employment sooner. Charges associated with employer contributions to the Plan were $9.3 million and $7.7 million for the years ended December 31, 2017 and 2016, respectively. Defined Benefit Pension and Postretirement Plans In conjunction with the Separation, Ingevity employees stopped participating in WestRock pension and post-retirement benefit plans. On May 16, 2016, Ingevity established new qualified and non-qualified benefit plans, similar in design to the WestRock plans, to continue the pension and post-retirement benefits provided to our employees and retirees based on the obligations assumed from WestRock. As further defined by the EMA, Ingevity assumed certain domestic and international pension and other post-retirement benefit obligations from WestRock on the date of Separation. The assumed retirement obligations consisted of accrued defined benefit obligations earned by Ingevity domestic hourly union employees, as of the day of Separation, net of contributed assets; 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 in 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. 84 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 The following table summarizes the weighted average assumptions used and components of our defined benefit postretirement plans.

Asset balance is included in "Other assets" and liability balances are included in "Other liabilities" on the consolidated balance sheet. 85 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 Amounts Recognized in Other Comprehensive Income (Loss) Changes in plan assets and benefit obligations recognized in other comprehensive income (loss) are as follows: Pensions Other Benefits Years Ended December 31, In millions Current year net actuarial loss (gain) Current year prior service cost (credit) Total recognized in other comprehensive (income) loss, before taxes Total recognized in other comprehensive (income) loss, after taxes 2017 2016 2017 2016 $ $ 1.1 — 1.1 0.7 $ $ 0.9 0.1 1.0 0.5 $ $ $ 0.1 — 0.1 — $ (0.1) — (0.1) 0.1 _______________ (1) This also represents the accumulated other comprehensive income (loss), net of tax as of December 31, 2017 and 2016. The estimated net actuarial loss and prior service cost that will be amortized from accumulated other comprehensive income (loss) into our net annual benefit cost during 2018 are zero and less than $0.1 million, respectively.

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. Amounts are recorded to "Cost of sales" on our consolidated statements of operations consistent with the employee compensation costs that participate in the plan. Amounts are recorded to "Other (income) expense, net" on our consolidated statements of operations. (2) (3) Contributions We made a voluntary cash contribution of $1.2 million to our Union Hourly defined benefit pension plan in the year ended December 31, 2017. There are no required cash contributions to our Union Hourly defined benefit pension plan in 2018, and we currently have no plans to make any voluntary cash contributions in 2018. 86 Index Fair Value Hierarchy Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 The following table presents our fair value hierarchy for our major categories of pension plan assets by asset class.

Prior to the Separation, these costs were primarily related to third-party professional fees associated with separation activities and one-time costs of new hires specifically required to separate and stand up Ingevity. Post-Separation, these costs represent legal, information technology and other advisory fees to transition from a division of WestRock to a stand- alone public company. In millions Separation costs Years Ended December 31, 2017 2016 2015 $ 0.9 $ 17.5 $ 17.2 Note 15: Restructuring and Other (Income) Charges, net We continually 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 as restructuring and other (income) charges, net recorded within Restructuring and other (income) charges, net on our consolidated statement of operations. These costs are excluded from our operating segment results. We record an accrual for severance and other non-recurring 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. Below provides detail of the restructuring and other (income) charges, net incurred. 2017 activities In January 2017, we initiated a reorganization to streamline our leadership team, flatten the organization and reduce costs. Because of this reorganization, we recorded $1.3 million, in severance and other employee-related costs for the year ended December 31, 2017. During the year ended December 31, 2017, we also recorded $2.4 million of additional miscellaneous exit costs primarily associated with the exit of our Performance Chemicals' manufacturing operations in Palmeira, Santa Catarina, Brazil which began in the fourth quarter of 2016 (see 2016 activities below). 2016 activities As a result of continued deteriorating market conditions within the South America region, on October 31, 2016, our Board of Directors approved a plan to exit our Performance Chemicals' manufacturing operations in Palmeira, Santa Catarina, Brazil. As a result, we recorded a non-cash pre-tax impairment charge to property, plant and equipment in the amount of $30.2 million and recorded severance costs of $1.8 million. The severance costs began to be paid in the fourth quarter of 2016. Refinery production ceased before year end, and the facility was decommissioned in 2017. We recorded $2.6 million of additional miscellaneous exit costs during the year ended December 31, 2016. During the first quarter of 2016, we announced the closure of the Performance Chemicals' derivatives operation in Duque de Caxias, Rio de Janeiro, Brazil. As a result of this closure, we recorded $0.1 million impairment charge on fixed assets, $1.8 million in severance and other employee-related costs and $1.7 million of additional miscellaneous exit costs during year ended December 31, 2016. During the first quarter of 2016, we also announced a company-wide restructuring to better align our workforce in light of changing macroeconomic and market realities. The restructuring decision resulted in workforce reductions at several of our locations. As a result, during the year ended December 31, 2016, we recorded severance and other employee-related charges of $2.7 million ($1.9 million related to Performance Chemicals segment and $0.8 million related to Performance Materials segment). We also recorded an impairment charge on fixed assets of $0.3 million in the year ended December 31, 2016 (related to the Performance Chemicals segment). 88 Index 2015 activities Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 During 2015, we sold our 60 percent interest in a subsidiary in China for cash proceeds of $11.5 million and recorded a gain on the sales of the subsidiary of $10.3 million. Prior to its sale, this subsidiary operated under our Performance Materials operating segment. Additionally during 2015, we recognized income of $1.2 million associated with the sale of our Performance Materials' air purification business in 2014. As part of a plan that was implemented to restructure a portion of our operations during 2015, we recorded an impairment of $4.0 million to write down inventory and property, plant and equipment associated with certain manufacturing operations of our Performance Chemicals segment.

The purchase price for the Acquisition is $315 million, subject to a customary adjustment to reflect normalized working capital for the Pine Chemical Business. In addition to the purchase price, at the closing of the Acquisition, we will assume certain liabilities related to the Pine Chemical Business. We intend to use the net proceeds from the sale of the the Notes to finance the Acquisition. The closing of the Acquisition is subject to regulatory clearance and other customary closing conditions, which are currently ongoing. Pursuant to the Purchase Agreement, GP has agreed to indemnify the Company for losses resulting from a breach of certain representations and warranties and excluded liabilities, subject to certain limitations. Furthermore, the Purchase Agreement contains various termination provisions available to the parties thereto. In addition, at the closing of the Acquisition, the Company and GP intend to enter into certain transition and shared services agreements to effectuate the transfer of the assets pursuant to the Acquisition. Separately, at the closing of the Acquisition, Ingevity and GP will also enter into a supply agreement, whereby certain of GP’s paper mills will supply CTO to Ingevity at market-based prices for a term of 20 years. Acquisition costs Pursuant to GAAP, costs incurred to complete the Acquisition are expensed as incurred. Charges incurred in connection with the planned Acquisition were $7.1 million, zero and zero for the years ended December 31, 2017, 2016 and 2015, respectively. These costs represent transaction costs and legal and professional third-party fees.

The decrease in our effective tax rate is mainly due to U.S. Tax Reform, which was enacted in December 2017. Our U.S. net deferred tax liabilities as of December 31, 2017 were remeasured from 35.0 percent to 21.0 percent, resulting in $24.5 million of provisional deferred income tax benefit and a reduction in our effective tax rate of 14.0 percent. The remaining difference in our effective tax rate for the years ended December 31, 2017 and 2016, respectively, is due to non-deductible transaction costs associated with the Separation in 2016, acquisition-related charges, restructuring and other (income charges) and the unfavorable results of legal entities with full valuation allowances. Excluding the impact of U.S. Tax Reform, acquisition-related charges, restructuring 91 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 and other (income charges), separation costs and losses from legal entities with full valuation allowances the change in the effective tax rate period over period was primarily due to a shift in earnings mix as it relates to domestic versus foreign income earned. The significant components of deferred tax assets and liabilities are as follows: In millions Deferred tax assets: Accrued restructuring Employee benefits Intangibles Investment in partnership Net operating losses Start-up costs Inventory Other Total deferred tax assets Valuation allowance Total deferred tax assets, net of valuation allowance Deferred tax liabilities: Fixed assets Inventory Other Total deferred tax liabilities Net deferred tax asset (liability) December 31, 2017 2016 $ $ $ $ $ $ $ $ $ $ 11.4 8.0 3.0 1.8 9.0 0.8 1.2 5.0 40.2 (20.4) 19.8 57.1 — 0.6 57.7 $ (37.9) $ 12.6 12.3 5.8 1.4 5.4 1.0 — 2.3 40.8 (18.8) 22.0 86.9 1.0 0.5 88.4 (66.4) On December 22, 2017, U.S. Tax Reform was signed into law making significant changes to the U.S. Internal Revenue Code ("IRC"). Changes include, but are not limited to, a corporate tax rate decrease from 35.0 percent to 21.0 percent effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. We have calculated our best estimate of the impact of U.S. Tax Reform in our year end income tax provision in accordance with our understanding of the changes to the IRC and guidance available as of the date of this filing. We recorded a provisional $24.5 million income tax benefit in the fourth quarter of 2017, the period in which the legislation was enacted. No additional expense was recorded in relation to the one-time transition tax on the mandatory deemed repatriation of foreign earnings. On December 22, 2017, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of U.S. Tax Reform. In accordance with SAB 118, we have determined that the $24.5 million of the provisional deferred tax expense recorded in connection with the re-measurement of certain deferred tax assets and liabilities and zero current tax expense recorded in connection with any other provisions of U.S. Tax Reform were reasonable estimates at December 31, 2017. Additional work may be necessary as the U.S. Treasury Department, the IRS, or other standard setting bodies interpret or issue new guidance on how the provisions of U.S. Tax Reform should be applied that may be different from our interpretation as of the date of this filing. Any subsequent adjustment to these amounts will be recorded to current tax expense in the period when the analysis is complete. In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income ("GILTI") provisions of the U.S. Tax Reform. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period cost are both acceptable methods subject to an accounting policy 92 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 election. Effective the first quarter of 2018, we will elect to treat any potential GILTI inclusions as a period cost as we are not projecting any material impact from GILTI inclusions and any deferred taxes related to any inclusion would be immaterial. We have deferred tax assets, including net operating loss 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. At December 31, 2017, foreign net operating loss carryforwards totaled $27.7 million. Of this total, $6.0 million will expire in 3 to 10 years and $21.7 million has no expiration date. At December 31, 2017 and 2016, 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 U.S. Tax Reform. Positive undistributed earnings considered to be indefinitely reinvested totaled less than $1.0 million at December 31, 2017. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows: In millions Balance at beginning of year Additions for tax positions related to current year Additions for tax positions related to prior years Reductions for tax positions related to prior years Reduction from lapse of statute of limitation Balance at end of year December 31, 2017 2016 2015 $ $ 0.6 — 0.1 — (0.4) 0.3 $ 0.7 $ — 0.1 (0.2) — $ 0.6 $ 0.8 0.1 0.1 (0.2) (0.1) 0.7 As of December 31, 2017, 2016 and 2015, $0.5 million, $1.0 million, and $1.2 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. As a result of lapse in statute of limitations, management anticipates a decrease in the accrual for unrecognized tax benefit of $0.4 million in the next twelve months. We operate in multiple jurisdictions around the world and as such are subject, at times, to tax audits in these jurisdictions. Under the TMA with WestRock, we are not responsible for U.S. federal, state and local income tax examinations prior to the Separation. Note 18: Commitments and Contingencies Lease commitments Capital leases The capital lease obligations consist of $80.0 million at December 31, 2017 and 2016 owed to the city of Wickliffe, Kentucky, associated with Performance Materials' Wickliffe, Kentucky site, which is due at maturity in 2027. The interest rate on the $80.0 million capital lease obligation is 7.67%. Interest payments are payable semi-annually. We have a capital lease obligation due in 2031, for certain assets located at our Purifications Cellutions manufacturing facility in Waynesboro, Georgia. 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 capital lease remain with Ingevity. Accordingly, we offset the capital lease obligation and bond on our consolidated balance sheets. Our DeRidder, Louisiana facility also had certain assets subject to a capital lease under 93 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 a similar arrangement as our Purifications Cellutions manufacturing facility. During the fourth quarter of 2017 the capital lease associated with the assets at our DeRidder, Louisiana facility subject to the lease was terminated. Thus, as of December 31, 2017, the assets are legally owned by Ingevity and no longer subject to a lease. The leased assets are presented within "Property, plant and equipment, net" on the consolidated balance sheets, see Note 7 for more information. Operating Leases We lease a variety of assets for use in our operations that are classified as operating leases. Our operating leases principally relate to leases for administrative offices, manufacturing equipment and buildings, warehousing and storage facilities, vehicles and rail cars. Certain leases provide for escalation of the lease payments as maintenance costs and taxes increase. Rental expense is recognized on a straight-line basis over the minimum lease term. Rental expense pursuant to operating leases was $16.8 million, $17.4 million and $16.5 million for the years ended December 31, 2017, 2016 and 2015, respectively. Minimum rental payments pursuant to agreements as of December 31, 2017, under operating leases that have non- cancelable lease terms in excess of 12 months and under capital leases are as follows: In millions 2018 2019 2020 2021 2022 Later years Minimum lease payments Less: amount representing interest Capital lease obligations Legal Proceedings Operating leases Capital leases $ $ 19.1 13.5 9.4 5.8 2.7 6.4 56.9 $ $ $ 6.1 6.1 6.1 6.1 6.1 107.8 138.3 (58.3) 80.0 We are, from time to time, involved in routine litigation incidental to our operations.

Note 19: Segment information Ingevity’s operating segments are (i) Performance Materials and (ii) Performance Chemicals, a description of both operating segments is included below. Performance Materials The Performance Materials segment manufactures and sells activated carbon products in the form of powder, granular, extruded pellets or structured honeycombs and activated carbon sheets which target gasoline vapor emission control within the automotive industry as well as the food, water, beverage and chemical purification industries. In addition, extruded pellets and structured honeycomb products are used for air emissions control, corrosion protection and odor reduction. Performance Chemicals The Performance Chemicals segment manufactures and sells products that are derived from CTO and lignin that are extracted from the kraft papermaking process. These materials are processed to make specialty chemicals that are used in the papermaking, adhesives, publication inks, rubber, asphalt, oilfield, bio-fuels, agriculture, dyestuffs and other industrial applications. The CTO-based products are produced by fractionating the CTO through a bio-refinery into intermediate products. The intermediates are either sold off or further processed into different specialty formulations to create increased value. 94 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 In millions Net sales Performance Materials Performance Chemicals Total net sales (1) Segment operating profit (2) Performance Materials Performance Chemicals Total segment operating profit (1) Separation costs (3) Restructuring and other income (charges) (4) Acquisition costs Interest expense Interest income (Provision) benefit for income taxes Years Ended December 31, 2017 2016 2015 $ $ 349.3 623.1 972.4 122.0 80.3 202.3 (0.9) (3.7) (7.1) (18.1) 2.3 (29.6) (18.7) 126.5 $ 301.0 607.3 908.3 106.9 56.7 163.6 (17.5) (41.2) — (19.3) 1.4 (42.6) (9.2) 35.2 $ $ 256.4 701.9 958.3 79.7 86.6 166.3 (17.2) 7.5 — (20.1) — (52.2) (4.6) 79.7 Net (income) loss attributable to noncontrolling interests Net income (loss) attributable to Ingevity stockholders $ _______________ (1) (2) Relates to external customers only, all intersegment sales and related profit have been eliminated in consolidation.

Note 20: Earnings (Loss) 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. The weighted average number of common shares outstanding for basic and diluted earnings (loss) per share for the year ended December 31, 2016 was based on the weighted average number of common shares outstanding for the period beginning after the Distribution Date. The weighted average number of common shares outstanding for basic and diluted earnings per share for the year ended December 31, 2015 was based on the number of shares of Ingevity common stock outstanding on the Distribution Date. On May 15, 2016, the Distribution Date, each holder of WestRock's common stock received one share of Ingevity's common stock for every six shares of WestRock's common stock held on the Record Date. 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 anti-dilutive common shares. 97 Index Ingevity Corporation Notes to the Consolidated Financial Statements December 31, 2017 In millions (except share and per share data) Net income (loss) attributable to Ingevity stockholders Basic and Diluted earnings (loss) per share (1) Basic earnings (loss) per share Diluted earnings (loss) per share Shares (2) Years Ended December 31, 2017 2016 2015 126.5 $ 35.2 $ 79.7 3.00 2.97 $ $ 0.83 0.83 $ $ 1.89 1.89 $ $ $ Weighted average number of shares of common stock outstanding - Basic Weighted average additional shares assuming conversion of potential common shares Shares - diluted basis 42,130 42,108 42,102 399 42,529 163 42,271 — 42,102 _______________ (1) Diluted earnings (loss) per share is calculated using net income (loss) available to common stockholders divided by diluted weighted-average shares of common shares outstanding during each period, which includes the dilutive effect of outstanding equity awards.

FORTSON John C. Fortson Executive Vice President, Chief Financial Officer and Treasurer 115 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. These financial measures are not meant to be considered in isolation or as a substitute for the most directly comparable financial measure calculated in accordance with GAAP. The company believes these non-GAAP measures provide 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 and projected future results. Ingevity also uses the above financial measures as the primary measures of profitability used by managers of the business and its segments. In addition, Ingevity believes Adjusted EBITDA, Adjusted EBITDA Margin and Segment EBITDA are useful measures because they exclude the effects of financing and investment activities as well as non-operating activities. These non-GAAP financial measures are 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. Reconciliations of these non-GAAP financial measures are set forth within the following pages. Unaudited Pro Forma Adjustments The non-GAAP financial measures noted above, adjusted for the Unaudited Pro Forma Adjustments, apply only to our quarterly periods within and fiscal year ended December 31, 2015. The Unaudited Pro Forma Adjustments are from the Unaudited Pro Forma Combined Financial Statements which were derived from the historical Combined Financial Statements of Ingevity, prepared in accordance with U.S. generally accepted accounting principles. These Unaudited Pro Forma Combined Financial Statements include adjustments required by SEC Staff Accounting Bulletin Topic 1:B-3 and Article 11 of SEC Regulation S-X. For more information regarding the Ingevity’s unaudited pro forma combined statements of operations for the year ended December 31, 2015, see “Unaudited Pro Forma Combined Financial Statements” in the Ingevity’s registration statement on Form 10 and amendments thereto (the “Form 10”), copies of which may be obtained by visiting the web site of the Securities and Exchange Commission, or the SEC, at www.sec.gov. The "Unaudited Pro Forma Combined Statement of Operations" included within Ingevity's registration statement on Form 10 is presented for the fiscal year ended December 31, 2015 and gives effect as if the pro forma adjustments had occurred on January 1, the first day of fiscal year 2015. Ingevity uses the following non-GAAP measures, inclusive of pro forma adjustments reconciled to the nearest GAAP financial measure, which are included below: Diluted adjusted earnings (loss) per share is defined as diluted earnings (loss) per common share attributable to Ingevity stockholders plus restructuring and other (income) charges, net per share, separation costs per share, acquisition costs per share, and the income tax expense (benefit) per share on those items less the per share tax benefit from U.S. Tax Reform.
