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

Introduction

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

27

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

All references to notes (herein referred to as "Note") in this section refer to the notes accompanying the Consolidated Financial Statements included in Part II. Item 8 within this Form 10-K.

Overview

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

Recent Developments

Interest Rate Risk Management

During the third quarter of 2024, we entered into a floating-to-fixed interest rate swap with a notional amount of $200.0 million to manage the variability of cash flows in the interest rate payments associated with our existing Secured Overnight Financing Rate ("SOFR") based interest payments, effectively converting $200.0 million of our floating rate debt to a fixed rate. In accordance with the terms of this instrument, we receive floating rate interest payments based upon one-month U.S. dollar SOFR and in return are obligated to pay interest at a fixed rate of 3.84 percent until August 2026. The fair value of outstanding interest rate instruments at December 31, 2024 and 2023 was an asset of $0.6 million and zero, respectively.

Measurement Alternative Investments

For the year ended December 31, 2024, the Company identified triggering events indicating that investments being accounted for under the measurement alternative may be impaired and recognized impairment charges of $11.5 million, recorded in Other (income) expense, net on the consolidated statement of operations.

Impairment Assessment(s) and Goodwill Impairment Charge

Impairment Assessment

Our fiscal year 2024 annual goodwill impairment assessment was performed as of October 1, 2024. We determined that the fair value of our reporting units were in excess of their carrying value and therefore concluded that no goodwill impairment existed.

The results of our October 1st annual review calculated that our APT reporting unit headroom, defined as the percentage difference between the fair value of a reporting unit and its carrying value, is 12 percent. Since the fair value of our APT reporting unit is higher than the carrying value, we have concluded that no impairment to goodwill is necessary. Our analysis includes significant assumptions such as revenue growth rate, Earnings before Interest, Taxes, Depreciation and Amortization ("EBITDA") margin, and discount rate, which are judgmental, and variations in any assumptions could result in materially different calculations of fair value.

28

There were no events or circumstances indicating that goodwill might be impaired as of December 31, 2024.

Goodwill Impairment Charge

Beginning in fiscal year 2023, we began to see depressed volumes in our industrial end markets, constraining our ability to offset the continued crude tall oil (“CTO”) price inflation we were experiencing, and negatively impacting earnings and cash flow within our Performance Chemicals reporting unit, particularly in our industrial specialties product line. As a result, we concluded that a triggering event occurred in the third quarter of 2023. Our third quarter 2023 impairment analysis included significant assumptions, such as the execution of several measures in 2023 to pursue greater cost efficiency, including a reorganization to streamline certain functions and reduce ongoing costs, and expectations of decreased CTO costs beginning in the second half of 2024. We concluded that no impairment was necessary as a result of that third quarter 2023 interim analysis or at our annual impairment assessment, dated October 1, 2023.

During the second quarter of 2024, our contracted long-term supplier of CTO provided new information regarding the cost of CTO for the second half of 2024, which significantly exceeded our forecasted costs, resulting in a triggering event for our Performance Chemicals reporting unit. We performed an analysis of the reporting unit’s goodwill, intangibles, and long-lived assets. Our analysis included significant assumptions such as: revenue growth rate, EBITDA margin, and discount rate, which are judgmental, and variations in any assumptions could result in materially different calculations of fair value.

Our analysis reassessed the expected cash flows in light of current performance and expected lack of near term recovery in our industrial specialties product line, resulting in lower volume and profitability expectations. As a result, we concluded that the carrying amount of the Performance Chemicals reporting unit exceeded its fair value, resulting in a non-cash goodwill impairment charge of $349.1 million, which represented all of the goodwill within the Performance Chemicals' reportable segment. The charge was is included within Goodwill impairment charge on the consolidated statements of operations for the year ended December 31, 2024. Specific to our long-lived assets, we determined that the undiscounted cash flows were in excess of the carrying values and therefore concluded that no impairment existed.

Performance Chemicals' Repositioning

On November 1, 2023, we announced a number of strategic actions designed to reposition our Performance Chemicals reportable segment to improve profitability and reduce the cyclicality of the Company as a whole. These actions increased our focus on growing our most profitable Performance Chemicals product lines, such as road technologies, and diversifying our raw material stream to non-CTO based fatty acids. The repositioning focused on reducing exposure to lower margin end-use markets of our industrial specialties product line, such as adhesives, publication inks, and oilfield, representing approximately 45 percent of our industrial specialties product line's historical annualized net sales. The repositioning included the permanent closure of our Performance Chemicals CTO refinery and our manufacturing plant located in DeRidder, Louisiana (the “DeRidder Plant”), including the polyol production assets associated with the APT reportable segment. All production at the DeRidder Plant ceased in the first quarter of 2024. The Performance Chemicals’ repositioning initiative included additional corporate and business cost reduction actions executed in November 2023.

Additionally, in July 2024, we announced plans to transition the refining of oleo-based products manufactured for our Performance Chemicals reportable segment from our Crossett, Arkansas manufacturing plant (the “Crossett Facility”) to our North Charleston, South Carolina manufacturing plant. This action included the closure of the Crossett Facility, as well as additional corporate and business cost reduction actions. We ceased production at the Crossett Facility in the third quarter of 2024.

The actions referenced above, when combined with other targeted workforce reduction initiatives, during 2024 and 2023 resulted in the reduction of Ingevity's global workforce by 23 percent. Specific to Performance Chemicals, the reduction represented approximately 40 percent of the reportable segment's workforce.

Expected Charges

We expect to incur total charges of approximately $350.0 million, excluding CTO resale activity as described below, associated with the Performance Chemicals repositioning, consisting of approximately $250.0 million in asset-related charges, approximately $25.0 million in severance and other employee-related costs, and approximately $75.0 million in other restructuring costs including decommissioning, dismantling and removal charges, and contract termination costs. We expect approximately $250.0 million of the total charges to be non-cash and $100.0 million to be settled in cash. Through December 31, 2024, we have incurred $311.8 million associated with these actions, including $244.8 million of non-cash asset-

29

related charges, excluding $7.4 million related to an asset retirement obligation ("ARO"), and $67.0 million of charges to be settled in cash, which includes the aforementioned ARO. As of December 31, 2024, $54.5 million of the charges to be settled in cash have been paid and all non-cash charges have been incurred. In total, we expect approximately $100 million of cash charges, including approximately $20-$25 million during 2025.

Inventory Charges

The Company believes the collective actions of workforce, operational, and regional business exits will hinder our ability to dispose of the associated inventory on hand. As a result, in the years ended December 31, 2024 and 2023, we recorded $6.3 million and $19.7 million, respectively, of non-cash, lower of cost or market, inventory charges to adjust the carrying value of the impacted inventory to what we will realize upon disposal, less disposal costs. These inventory charges are recorded to Cost of sales on the consolidated statement of operations. Since these inventory charges are directly attributable to the Performance Chemicals’ repositioning, that is, they do not represent normal, recurring expenses necessary to operate our business, we have excluded such impact from the financial results of our Performance Chemicals reportable segment. Refer to Note 19 for more information.

CTO Resale Activity

The DeRidder Plant closure, and the corresponding reduced CTO refining capacity, significantly reduced our CTO volume requirements. However, we were obligated under an existing CTO supply contract to purchase CTO volumes through 2025 at amounts in excess of the CTO volumes needed to support our business operations. To manage this excess inventory, we sold CTO volumes (herein referred to as "CTO resales") in the open market. During the years ended December 31, 2024 and 2023, we incurred $52.7 million and $22.0 million of CTO resale losses, which are recorded as Other (income) expense, net on the consolidated statements of operations. Refer to Note 2, under the section: Non-operating income and expense, for more information.

As of July 1, 2024, we terminated the CTO supply contract that resulted in these excess CTO volumes. As consideration for the early termination of the CTO supply contract, we made cash payments totaling $100.0 million. The total charge was recorded within Other (income) expense, net on the consolidated statements of operations for the year ended December 31, 2024. As a result of the termination, the purchases under the CTO supply contract ended effective June 30, 2024. The CTO resale activity described above ended in 2024 and no excess CTO volumes were on hand at December 31, 2024.

Expected Savings and Impact

The Performance Chemicals' repositioning, which began in November 2023, was focused on reducing exposure to lower margin end-use markets of our industrial specialties product line, such as adhesives, publication inks, and oilfield. Sales into these end-use markets represented approximately 45 percent of our industrial specialties product line historical annualized net sales. As a result of this initiative, we expect to realize savings of approximately $95 million to $110 million. These cash savings are derived from headcount reductions, plant operating efficiencies, and reduced supply chain costs. During the year ended December 31, 2024, we realized cash savings of approximately $84.0 million, including $68.0 million in Cost of sales, $12.0 million in Selling, general, and administrative expenses, and $4.0 million in Research and technical expenses, respectively. Collectively, these savings are realized in the following financial statement captions: 70-80 percent in Cost of sales, 15-25 percent in Selling, general, and administrative expenses, and ~5 percent in Research and technical expenses, all presented on our consolidated statements of operations. We expect to realize the remaining savings in 2025.

In addition to the cash savings, we expect to realize approximately $15 million to $17 million in depreciation and intangible amortization expenses, respectively. During the year ended December 31, 2024, we realized savings of approximately $10 million. We expect to realize the remaining savings in 2025.

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

Results of Operations

Net sales

The table below shows 2024 and 2023 Net sales and variances from 2023 and 2022, respectively.

2024 Performance Summary

The Net sales decrease was driven primarily by the Performance Chemicals industrial specialties product line due to repositioning actions that have resulted in the reduction of sales to lower margin end-use markets, therefore reducing Net sales during the year by approximately $210 million. Also contributing to the lower sales was unfavorable weather in key North American regions impacting the Performance Chemicals road technologies product line contributing to the decline in Net sales of $27.5 million, continued weakness in certain industrial end markets that negatively impacted sales in the Performance Chemicals industrial specialties product line that contributed to the reduction in Net sales of $56.4 million, and lower sales in our Advanced Polymer Technologies reportable segment of $15.4 million, partially offset by an increase in our Performance Materials reportable segment of $23.6 million.

Year Ended December 31, 2024 vs. 2023

The Net sales decrease in 2024 was driven by volume decline of $274.9 million (16 percent), unfavorable foreign exchange impacts of $9.8 million (one percent), and unfavorable pricing and sales mix of $1.0 million (zero percent).

Year Ended December 31, 2023 vs. 2022

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

31

Gross profit

Year Ended December 31, 2024 vs. 2023

Gross profit decrease of $17.2 million was driven by unfavorable sales volume of $35.8 million, unfavorable pricing and sales mix of $6.4 million, and unfavorable foreign exchange impacts of $2.9 million, partially offset by decreased manufacturing costs of $27.9 million. Gross profit includes the realized savings of $68.0 million from the Performance Chemicals repositioning action initiated in 2023. Refer to the Segment Operating Results section included within this MD&A for more information on the drivers of the changes in gross profit period over period for all segments.

Year Ended December 31, 2023 vs. 2022

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

Selling, general, and administrative expenses

Year Ended December 31, 2024 vs. 2023

Selling, general, and administrative ("SG&A") expenses were $166.7 million (12 percent of Net sales) and $183.7 million (11 percent of Net sales) for the years ended December 31, 2024 and 2023, respectively. Overall, SG&A decreased by approximately $17.0 million or nine percent. Our Performance Chemicals' repositioning actions resulted in a non-cash reduction of intangible amortization expense of $11.4 million and $12.0 million in cash savings. These combined savings were partially offset by increased spending on commercial activities of $1.0 million and increased variable incentive compensation of $5.4 million, driven by adjustments recognized in the year ended December 31, 2023, that did not repeat in 2024.

Year Ended December 31, 2023 vs. 2022

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

Research and technical expenses

Years Ended December 31, 2024, 2023, and 2022

Research and technical expenses as a percentage of Net sales remained relatively consistent period over period, totaling 2.0 percent of sales in the year ended December 31, 2024, compared to 1.9 percent in the year ended December 31, 2023, and 1.8 percent in the year ended December 31, 2022. Research and technical expenses as a percentage of Net sales increased due to lower sales. Overall, Research and technical expense decreased by $3.7 million in 2024, compared to 2023, which included approximately $4.0 million realized from the Performance Chemicals repositioning actions initiated in 2023.

Segment Operating Results

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

Performance Materials

2024 Performance Summary

Performance Materials delivered record Net sales, Segment EBITDA, and Segment EBITDA margins. Sales growth of four percent was driven by higher volume and improved price and mix. There are two components to mix that are key to understanding this reportable segment. The segment benefits from larger vehicles, such as trucks and sport utility vehicles, as well as more hybrids and internal combustion engine vehicles versus all electric vehicles, as these vehicles contain more of our activated carbon content. Regional mix is also important as North America, which is nearly 50 percent of Performance Material sales, is our most profitable region due to the typically larger size of vehicles requiring more content, and this region also has the highest emissions control standards in the world requiring more advanced forms of our activated carbon product. Asia Pacific is also an important region, representing about 40 percent of total Performance Materials net sales. Within Asia Pacific, about half of our net sales are in China and the remaining are made up primarily of South Korea and Japan. All of these countries have strict emissions control standards or strong export markets where our activated carbon plays an important role in meeting regulations. Europe is our least impactful region due to the regulatory environment favoring electric vehicles, and also because European emissions standards lag behind North America and Asia Pacific. Segment EBITDA for Performance Materials increased 11 percent to $319.1 million, with Segment EBITDA margins for the year of 52.3 percent. This record result was primarily driven by operational improvements that enabled our production operations to run more efficiently which reduced our input costs by using less natural gas and also improved yields.

Net Sales Comparison of Years Ended December 31, 2024, 2023, and 2022

Year Ended December 31, 2024 vs. 2023

Segment net sales. The increase of $23.6 million in 2024 was driven by favorable pricing and sales mix of $17.3 million (three percent), and a volume increase of $11.2 million (two percent), partially offset by unfavorable foreign currency exchange impacts of $4.9 million (one percent).

35

Segment EBITDA. The increase of $32.5 million in 2024 was driven by decreased manufacturing costs of $26.0 million, pricing and sales mix of $11.9 million, and favorable volume of $6.3 million. The increase was partially offset by higher SG&A expenses and research and technical costs of $10.9 million, and unfavorable foreign currency exchange and other charges of $0.8 million.

Year Ended December 31, 2023 vs. 2022

Segment net sales. The increase in 2023 was driven by favorable pricing and sales mix of $32.2 million (six percent), and a volume increase of $17.3 million (three percent), partially offset by unfavorable foreign currency exchange impacts of $12.0 million (two percent).

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

Performance Chemicals

2024 Performance Summary

Performance Chemicals net sales of $608.2 million declined almost $300 million, a 33 percent decline, versus the prior year primarily as a result of our repositioning actions. Approximately $210 million of the decline in net sales reflects the exit of lower-margin end markets in our industrial specialties product line as we continue to focus on maximizing profitability. The remaining net sales decline was due primarily to lost sales as customers sought alternative suppliers in light of our repositioning actions and lower road technologies product line sales attributed to adverse weather in the key states within the U.S. The segment generated Segment EBITDA of $14.7 million for the year. The year over year decline in Segment EBITDA was driven by higher CTO costs and lower volumes, particularly in the road technologies product line, partially offset by cost savings realized due to the Performance Chemicals repositioning.

Net Sales Comparison of Years Ended December 31, 2024, 2023, and 2022

Year Ended December 31, 2024 vs. 2023

Segment net sales. The decrease of $293.9 million in 2024 was driven by a volume decrease of $293.2 million (33 percent), as a result of a decrease in industrial specialties ($262.4 million) and road technologies ($30.8 million), and unfavorable foreign currency exchange of $1.2 million (zero percent). The decrease was partially offset by favorable pricing

36

and sales mix of $0.5 million (zero percent), comprised of road technologies ($3.7 million), offset by industrial specialties ($3.2 million).

Segment EBITDA. The decrease of $51.0 million in 2024 was driven by a volume decrease of $45.0 million, higher manufacturing costs of $21.4 million, primarily due to higher cost CTO, and unfavorable foreign currency exchange and other charges of $5.1 million. The decrease was partially offset by favorable pricing and sales mix of $0.5 million and lower SG&A expenses of $20.0 million, which benefited from the Performance Chemicals' repositioning and cost savings initiatives implemented in 2023.

Year Ended December 31, 2023 vs. 2022

Segment net sales. The sales increase was driven by favorable pricing and sales mix of $93.1 million (11 percent), comprised of industrial specialties ($62.7 million) and road technologies product lines ($30.4 million), respectively. The increase was partially offset by a volume decline of $65.3 million (seven percent), driven by a decline in industrial specialties ($163.7 million), partially offset by growth in road technologies ($98.4 million). Unfavorable foreign currency exchange also impacted Net sales by $0.8 million (zero percent).

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

Advanced Polymer Technologies

2024 Performance Summary

Advanced Polymer Technologies generated higher volumes year over year as the segment made progress in end markets such as elastomers, adhesives, and coatings; however, unfavorable overall product mix and selective price concessions contributed to a revenue decline of eight percent. The segment benefited from lower energy costs and an improvement in utilization rates as a result of higher volumes but these cost savings were more than offset by the revenue decline, resulting in segment EBITDA of $35.2 million and a segment EBITDA margin of 18.7 percent.

Net Sales Comparison of Years Ended December 31, 2024, 2023, and 2022

Year Ended December 31, 2024 vs. 2023

Segment net sales. The decrease of $15.4 million in 2024 was driven by unfavorable pricing and sales mix of $18.8 million (nine percent), and unfavorable foreign currency exchange of $3.7 million (two percent), partially offset by volume growth of $7.1 million (three percent).

Segment EBITDA. The decrease of $9.3 million in 2024 was driven by unfavorable pricing and sales mix of $18.8 million, and unfavorable foreign currency exchange impacts and other charges of $2.8 million. The decrease was partially offset by lower manufacturing costs of $8.8 million, volume growth of $2.9 million, and lower SG&A expenses of $0.6 million.

37

Year Ended December 31, 2023 vs. 2022

Segment net sales. The sales decrease was driven by a volume decline of $58.3 million (24 percent), partially offset by favorable pricing and sales mix of $17.0 million (seven percent), and favorable foreign currency exchange of $0.6 million (zero percent).

Segment EBITDA. Segment EBITDA increased $4.5 million, mainly due to favorable pricing and sales mix of $17.1 million, decreased manufacturing costs of $9.9 million, and decreased SG&A expenses of $5.9 million. These increases were partially offset by volume declines of $23.7 million, and unfavorable foreign currency exchange impacts and other miscellaneous charges of $4.7 million.

38

Use of Non-GAAP Financial Measures

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

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

Adjusted EBITDA is defined as net income (loss) plus interest expense, net, provision (benefit) for income taxes, depreciation, amortization, restructuring and other (income) charges, net, acquisition and other-related (income) costs, goodwill impairment charge, litigation verdict charges, (loss) gain on strategic investments, loss on CTO resales, CTO supply contract termination charges, and pension and postretirement settlement and curtailment (income) charges, net.

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

(1) Refer to Note 19 for more information.

(2) We regularly perform strategic reviews and assess the return on our operations, which sometimes results in a plan to restructure the business. These costs are excluded from our reportable segment results and for the purposes of calculating our non-GAAP financial performance measures. Refer to Note 15 for more information on the charges.

(3) Refer to Note 8 for more information.

(4) Charges represent costs incurred to complete and integrate acquisitions and other strategic investments and include the expensing of the inventory fair value step-up resulting from the application of purchase accounting for acquisitions and certain legal and professional fees associated with the completion of acquisitions and strategic investments. Refer to Note 16 for more information.

(5) Due to the DeRidder Plant closure, and the corresponding reduced CTO refining capacity, we were obligated, under an existing CTO supply contract, to purchase CTO at amounts in excess of required CTO volumes. As of July 1, 2024, we terminated the CTO supply contract that resulted in these excess CTO volumes. As a result of the termination of this contract the purchases under the CTO supply contract ended, effective June 30, 2024, and we ended our CTO resale activity as of December 31, 2024. Since these CTO resale activities

39

are directly attributable to the Performance Chemicals’ repositioning, that is, they do not represent normal, recurring expenses necessary to operate our business, we have excluded the CTO resale (income) charges for the purposes of calculating our non-GAAP financial performance measures. For the years ended December 31, 2024 and 2023, the loss on CTO resales relates to the Performance Chemicals segment. Refer to Note 2 and Note 15 for more information.

(6) As consideration for the termination of the CTO supply contract, we made cash payments totaling $100.0 million during 2024. Since this contract termination is directly attributable to the Performance Chemicals’ repositioning, that is, it does not represent normal, recurring expenses necessary to operate our business, we have excluded the CTO supply contract termination charges for the purposes of calculating our non-GAAP financial performance measures. Refer to Note 2 and Note 15 for more information.

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

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

Revision to Previously Reported Adjusted EBITDA (Non-GAAP)

We revised our December 31, 2023 non-GAAP Adjusted EBITDA calculation to remove previous adjustments of $19.7 million related to inventory lower of cost or market charges associated with the Company's Performance Chemicals repositioning. This change was made to address a request from the Securities and Exchange Commission to revise future filings to no longer exclude these adjustments from non-GAAP performance measures. The following table presents the twelve months ended December 31, 2023 as previously reported and as revised.

Adjusted EBITDA

Year Ended December 31, 2024, 2023 and 2022

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

Current Full Year Company Outlook vs. Prior Year

Net sales are expected to be between $1.3 billion and $1.4 billion for 2025. We expect growth in our Performance Materials reportable segment due to increased pricing on select products while global automotive production remains flat compared to the prior year. For our Performance Chemicals reportable segment, we expect the industrial specialties product line to deliver Net sales between $160 and $200 million, which reflects the impact of our repositioning actions to improve profitability by focusing on higher margin end markets, as well as continued weak industrial demand. Additionally, we expect our road technologies product line Net sales to improve compared to 2024 as adverse weather conditions experienced in key states within the U.S. negatively impacted 2024. Our Advanced Polymer Technologies reportable segment anticipates modest growth as industrial demand recovery will be tempered by continued competitive dynamics, particularly in Asia.

Adjusted EBITDA is expected to be between $400 million and $415 million for 2025. We expect modest improvement in our Performance Materials reportable segment EBITDA, while maintaining segment EBITDA margins around 50 percent, as improved pricing and continued operational efficiencies will be muted by expected higher input costs, particularly energy, and higher spend on innovation activities. In our Performance Chemicals reportable segment, we expect improved segment EBITDA, with segment EBITDA margins in the mid-to-high single digits. The segment will benefit from revenue growth in our road technologies product line and further savings from our repositioning actions. While we expect to benefit from lower CTO costs in the latter part of the year, we expect these benefits to be offset by price concessions to align with market pricing. We anticipate that our Advanced Polymer Technologies segment EBITDA will improve versus prior year as our enacted pricing and mix strategies will produce segment EBITDA margins of around 20 percent.

A reconciliation of net income to adjusted EBITDA as projected for 2025 is not provided. Ingevity does not forecast net income as it cannot, without unreasonable effort, estimate or predict with certainty various components of net income. These components, net of tax, include further restructuring and other income (charges), net; additional acquisition and other-related income (costs); additional pension and postretirement settlement and curtailment (income) charges; and revisions due to legislative tax rate changes. Additionally, discrete tax items could drive variability in our projected effective tax rate. All of these components could significantly impact such financial measures. Further, in the future, other items with similar characteristics to those currently included in adjusted EBITDA, that have a similar impact on comparability of periods, and which are not known at this time, may exist and impact adjusted EBITDA.

Liquidity and Capital Resources

The primary source of liquidity for our business is the cash flow provided by operating activities. We expect our cash flow provided by operations combined with cash on hand and available capacity under our revolving credit facility to be sufficient to fund our planned operations and meet our interest and other contractual obligations for at least the next twelve months. As of December 31, 2024, our undrawn capacity under our revolving credit facility was $302.4 million. Over the next twelve months, we expect to fund the following: debt principal repayments, interest payments, capital expenditures, income tax payments, additional spending associated with our Performance Materials' intellectual property litigation, and restructuring activities such as the repositioning of our Performance Chemicals reportable segment as further described within Note 15. In addition, we may also evaluate and consider purchases pursuant to our stock repurchase program (and related excise tax payments), strategic acquisitions, joint ventures, or other transactions to create stockholder value and enhance financial performance. In connection with such transactions, or to fund other anticipated uses of cash, we may modify our existing revolving credit facility, redeem all or part of our outstanding senior notes, seek additional debt financing, issue equity securities, or some combination thereof.

Cash and cash equivalents totaled $68.0 million at December 31, 2024. We continuously monitor deposit concentrations and the credit quality of the financial institutions that hold our cash and cash equivalents, as well as the credit quality of our insurance providers, customers, and key suppliers.

Due to the global nature of our operations, a portion of our cash is held outside the U.S. The cash and cash equivalents balance at December 31, 2024, included $63.9 million held by our foreign subsidiaries. Cash and earnings of our foreign subsidiaries are generally used to finance our foreign operations and their capital expenditures. We believe that our foreign holdings of cash will not have a material adverse impact on our U.S. liquidity. If these earnings were distributed, such amounts would be subject to U.S. federal income tax at the statutory rate less the available foreign tax credits, if any, and would potentially be subject to withholding taxes in the various jurisdictions. The potential tax implications of the repatriation of unremitted earnings are driven by facts at the time of distribution, therefore, it is not practicable to estimate the income tax liabilities that might be incurred if such cash and earnings were repatriated to the U.S. Management does not currently expect to repatriate cash earnings from our foreign operations in order to fund U.S. operations.

Debt and Finance Lease Obligations

Refer to Note 10 for a summary of our outstanding debt obligations and revolving credit facility, and Note 13 for details of our lease obligations.

Other Potential Liquidity Needs

Share Repurchases

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

During the year ended December 31, 2024, we repurchased no common stock. At December 31, 2024, $353.4 million remained available for purchase under our Board-authorized repurchase program.

Capital Expenditures

Projected 2025 capital expenditures are expected to be $50 million to $70 million, the majority of which will be spent on maintenance and safety, health and environment projects. We have no material commitments associated with these projected capital expenditures as of December 31, 2024.

Cash flow comparison of Years Ended December 31, 2024, 2023, and 2022

Cash flows provided by (used in) operating activities

Cash provided by operating activities, which consists of net income (loss) adjusted for non-cash items including the cash impact from changes in operating assets and liabilities (i.e., working capital), totaled $128.6 million for the year ended December 31, 2024.

Cash provided by operating activities for 2024, when compared to 2023, decreased by $76.5 million. This decrease was driven by a payment to terminate a Performance Chemicals CTO contract of $100.0 million, reduced cash earnings of $75.8 million, CTO resale cash outflows of $35.5 million, increased spending on restructuring initiatives of $15.3 million, and an increase in cash interest paid of $2.7 million due primarily to rising interest rates when compared to 2023. Partially offsetting these cash outflows was a net reduction in trade working capital (accounts receivable, inventory, and accounts payable) of $108.5 million, reduced employee variable compensation of $41.5 million, and a reduction in tax payments of $2.8 million.

Cash provided by operating activities for 2023, when compared to 2022, decreased by $108.3 million. This decrease was driven by lower cash earnings of $41.4 million, increased employee compensation payments of $38.9 million, increased spending on restructuring initiatives of $30.2 million, an increase in cash interest paid of $27.9 million due to higher average debt levels resulting from the October 2022 acquisition of Ozark Materials and rising interest rates during 2023, and CTO resale cash outflows of $10.6 million. This was partially offset by a reduction in tax payments of $25.1 million, and a decrease in trade working capital (accounts receivable, inventory, and accounts payable) of $15.6 million.

Cash flows provided by (used in) investing activities

Cash used in investing activities for 2024 was primarily driven by capital spending. Capital spending included the base maintenance capital supporting ongoing operations and cost improvement and growth spending.

Cash used in investing activities for 2023 was driven by capital spending, offset partially by the proceeds from the sale of a strategic investment (refer to Note 5 for more information). Capital spending included the base maintenance capital supporting ongoing operations and cost improvement and growth spending in our Advanced Polymer Technologies segment.

Cash flows provided by (used in) financing activities

Cash used in financing activities for the year ended December 31, 2024, was $70.2 million and was primarily driven by net payments on the revolving credit facility and other borrowings of $66.1 million.

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

New Accounting Guidance

Refer to Note 3 for a full description of recent accounting pronouncements including the respective expected dates of adoption and expected effects on our Consolidated Financial Statements.

Critical Accounting Policies and Estimates

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

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

Revenue recognition

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

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

Valuation of tangible and intangible long-lived assets and goodwill

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

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

Goodwill represents the excess of cost of an acquired business over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed in a business combination. We conduct a required annual review of goodwill for potential impairment at October 1, or sooner if events or changes in circumstances indicate that the fair value of a reporting unit is below its carrying value. Our reporting units are our operating segments, i.e., Performance Materials, Performance Chemicals and Advanced Polymer Technologies. If the carrying value of a reporting unit that includes goodwill exceeds its fair

44

value, which is determined using both the income approach and market approach, goodwill is considered impaired. The income approach determines fair value based on discounted cash flow model derived from a reporting unit’s long-term forecasted cash flows. The market approach determines fair value based on the application of earnings multiples of comparable companies to the projected earnings of the reporting unit. The amount of impairment loss is measured as the difference between the carrying value and the fair value of a reporting unit but is limited to the total amount of goodwill allocated to the reporting unit. In performing the fair value analysis, management makes various judgments, estimates, and assumptions, the most significant of which are the assumptions related to revenue growth rates, Earnings before Interest, Taxes, Depreciation and Amortization ("EBITDA") margin, and discount rate.

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

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

The results of our October 1st annual review calculated that our APT reporting unit headroom, defined as the percentage difference between the fair value of a reporting unit and its carrying value, is 12 percent. Since the fair value of our APT reporting unit is higher than the carrying value, we have concluded that no impairment to goodwill is necessary. Our analysis includes significant assumptions such as revenue growth rate, Earnings before Interest, Taxes, Depreciation and Amortization ("EBITDA") margin, and discount rate, which are judgmental, and variations in any assumptions could result in materially different calculations of fair value.

The below table shows how changes in certain significant assumptions utilized in our annual goodwill testing, specific to our APT reporting unit, impacts the calculated headroom.

Business Combinations

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

The fair value assigned to identifiable intangible assets acquired is determined primarily by using an income approach, which is based on assumptions and estimates made by management. Significant assumptions utilized in the income approach are the attrition rate, revenue growth rates, EBITDA margins, royalty rates, and the discount rate. These assumptions are based on company-specific information and projections, which are not observable in the market and are therefore considered Level 2 and Level 3 measurements. The excess of the purchase price over the fair value of the identified assets and liabilities is recorded

45

as goodwill. Based on the acquired business’ end markets and products, as well as how the chief operating decision maker will review the business results, determines the most appropriate operating segment for which to integrate the acquired business. Goodwill acquired, if any, is allocated to the reporting unit within or at the operating segment for which the acquired business will be integrated. Selection of the appropriate reporting unit is based on the level at which discrete financial information is available and reviewed by business management post-integration. Operating results of the acquired entity are reflected within the Consolidated Financial Statements from the date of acquisition.

Income taxes

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

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