(Unaudited)

Note 1: Background

Description of Business

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

Basis of Consolidation and Presentation

These unaudited Condensed Consolidated Financial Statements reflect the consolidated operations of the company and have been prepared in accordance with United States Securities and Exchange Commission ("SEC") interim reporting requirements. Accordingly, the accompanying Condensed Consolidated Financial Statements do not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP") for full financial statements and should be read in conjunction with the Annual Consolidated Financial Statements for the years ended December 31, 2024, 2023 and 2022, collectively referred to as the “Annual Consolidated Financial Statements,” included in our Annual Report on Form 10-K for the year ended December 31, 2024 (the "2024 Annual Report").

In the opinion of management, the Condensed Consolidated Financial Statements contain all adjustments which include only normal recurring adjustments necessary to fairly present the financial position, results of operations, and cash flows for the interim periods presented and contain adequate disclosures to make the information presented not misleading. The consolidated results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.

The preparation of the Condensed Consolidated Financial Statements requires management to make estimates and assumptions with respect to the reported amounts of assets, liabilities, revenue, and expenses and the disclosure of contingent assets and liabilities. Actual results could differ from these estimates.

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

Note 2: New Accounting Guidance

The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC" or "Codification") is the sole source of authoritative GAAP other than SEC issued rules and regulations that apply only to SEC registrants. The FASB issues an Accounting Standards Update ("ASU") to communicate changes to the Codification. We consider the applicability and impact of all ASUs. Recently issued ASUs that are not listed within this Form 10-Q have been assessed and determined to be either not applicable or are not expected to have a material impact on the Condensed Consolidated Financial Statements.

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures,” which is intended to enhance income tax disclosures around the rate reconciliation and income taxes paid. The purpose of the amendment is to provide readers of the financial statements with information to better assess the differences between the effective tax rate and the statutory tax rate across multiple jurisdictions, enabling them to understand tax implications around operational opportunities and potential future cash flows. The guidance is effective beginning with our 2025 fiscal year Form 10-K. We are currently evaluating the potential impact of adopting this new guidance on our Condensed Consolidated Financial Statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses,” which is intended to enhance disclosures regarding significant expenses. The purpose of the amendment is to provide readers of the financial statements with information to better understand an entity’s overall performance, assess potential future cash flows, and compare an entity's performance over time and with that of other entities. The guidance is effective beginning with our

Nonrecurring Fair Value Measurements

There were no nonrecurring fair value measurements on the condensed consolidated balance sheets during the periods ended June 30, 2025, and December 31, 2024.

Strategic Investments

Equity Method Investments

The aggregate carrying value of all strategic equity method investments totaled $15.9 million and $15.4 million at June 30, 2025 and December 31, 2024, respectively. As of June 30, 2025, we had approximately $4.6 million of unfunded commitments associated with a venture capital fund investment accounted for under the equity method of accounting. We anticipate this will be paid over a period of 10 years, beginning from the fourth quarter of 2022.

For the three and six months ended June 30, 2024, the company recognized a $0.1 million gain related to the sale of an equity method investment. There were no adjustments to the carrying value of equity method investments for impairment for the periods ended June 30, 2025 and December 31, 2024, respectively.

Measurement Alternative Investments

The aggregate carrying value of all measurement alternative investments where fair value is not readily determinable totaled $69.4 million and $71.9 million at June 30, 2025 and December 31, 2024, respectively.

During the second quarter of 2025 and the first quarter of 2024, the company identified trigger events indicating that certain investments being accounted for under the measurement alternative may be impaired. For the three and six months ended June 30, 2025, the company recognized an impairment of $2.5 million recorded in "Other (income) expense, net" on the condensed consolidated statements of operations. For the three and six months ended June 30, 2024, the company recognized an impairment of zero and $4.8 million, respectively, recorded in "Other (income) expense, net" on the condensed consolidated statements of operations.

Restricted Investment

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

At June 30, 2025 and December 31, 2024, the carrying value of our restricted investment was $83.0 million and $81.6 million, net of an allowance for credit losses of $0.2 million and $0.2 million, and included restricted cash of $29.8 million and $18.2 million, respectively. The fair value at June 30, 2025 and December 31, 2024 was $82.2 million and $80.3 million, respectively, based on Level 1 inputs.

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

_______________

(1) For both periods presented, the carrying value of our variable interest rate debt, including the impact of a $200.0 million floating-to-fixed interest rate swap, and excluding debt issuance fees is considered a reasonable estimate of the fair value.

(2) The carrying value of our fixed interest rate debt, for both periods presented, included the impact of a $200.0 million floating-to-fixed interest rate swap. As of June 30, 2025 and December 31, 2024, the fair value of our fixed rate debt was $725.5 million and $703.2 million, respectively, based on Level 2 inputs.

(3) At June 30, 2025 and December 31, 2024, the fair value of our $80.0 million finance lease obligation associated with our Performance Materials' Wickliffe, Kentucky manufacturing site was $82.1 million and $82.2 million, respectively, based on Level 2 inputs. The fair value of all other finance lease obligations approximates their carrying values.

During the six months ended June 30, 2025, lower raw material prices, primarily Crude Tall Oil ("CTO") within our Performance Chemicals reportable segment domestic inventory, resulted in a reduction to our LIFO reserve. Additionally, LIFO inventory quantities, primarily in our Performance Chemicals reportable segment domestic inventory, were reduced, which led to liquidations of LIFO inventory quantities. These planned reductions in inventory are not expected to be replaced by the end of the year and have resulted in a pre-tax decrease to the LIFO reserve of $6.5 million, recorded in "Cost of sales" on our condensed consolidated statement of operations.

Goodwill Impairment Charge - Advanced Polymer Technologies

During the second quarter of 2025, the announcements and subsequent modifications of international tariffs escalated global trade tensions and contributed to increased consumer uncertainty, which negatively impacted parts of our businesses, particularly Advanced Polymer Technologies (“APT”). As a result, we conducted an analysis of the APT reporting unit’s goodwill, intangible assets, and long-lived assets. This analysis incorporated revised expectations regarding the pace and strength of industrial demand recovery in key markets. In addition, the macroeconomic changes experienced during the quarter contributed to unfavorable movements in key valuation inputs, including an increase in the risk-free rate used in calculating the discount rate.

Our analysis included significant assumptions such as the revenue growth rate, earnings before interest, taxes, depreciation, and amortization ("EBITDA") margin, and discount rate, which are judgmental. Variations in any assumptions could result in materially different calculations of fair value.

Based on the results of the quantitative analysis, we concluded that the carrying value of the APT reporting unit exceeded its fair value. As a result, we recorded a non-cash goodwill impairment charge of $183.8 million, representing all of the goodwill associated with the APT reporting unit. The charge is included within Goodwill impairment charge on the condensed consolidated statements of operations for the three and six months ended June 30, 2025. 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.

Goodwill Impairment Charge - Performance Chemicals

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. 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 value 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 included within Goodwill impairment charge on the condensed consolidated statements of operations for the three and six months ended June 30, 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.

Commodity Price Risk Management

As of June 30, 2025, we had 1.8 million mmBTUS (millions of British Thermal Units) in open natural gas derivative contracts, designated as cash flow hedges. As of June 30, 2025, open natural gas derivative contracts hedge a portion of forecasted transactions until September 2026. The fair value of the open natural gas derivative contracts was a net asset (liability) of $(0.5) million and $0.3 million as of June 30, 2025 and December 31, 2024, respectively.

Interest Rate Risk Management

During the third quarter of 2024, we entered into a floating-to-fixed interest rate swap to convert a notional amount of $200.0 million of the variable, Secured Overnight Financing Rate ("SOFR") based interest component of our 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, which was 4.32 percent as of June 30, 2025, and in return are obligated to pay interest at a fixed rate of 3.84 percent until August 2026. The fair value of the interest rate swap was an asset (liability) of $(0.2) million and $0.6 million at June 30, 2025 and December 31, 2024, respectively.

Debt Covenants

Our indenture contains certain customary covenants (including covenants limiting Ingevity's and its restricted subsidiaries’ ability to grant or permit liens on certain property securing debt, declare or pay dividends, make distributions on or repurchase or redeem capital stock, make investments in unrestricted subsidiaries, engage in sale and lease-back transactions, and engage in a consolidation or merger, or sell, transfer or otherwise dispose of all or substantially all of the assets of Ingevity and our restricted subsidiaries, taken as a whole) and events of default (subject in certain cases to customary exceptions, as well as grace and cure periods). The occurrence of an event of default under the 2028 Senior Notes could result in the acceleration of the notes of such series and could cause a cross-default resulting in the acceleration of other indebtedness of Ingevity and its subsidiaries. We were in compliance with all covenants under the indenture as of June 30, 2025.

The credit agreement governing our revolving credit facility contains customary default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-compliance with covenants and cross-defaults to other material indebtedness. The occurrence of an uncured event of default under the credit agreement could result in all loans and other obligations becoming immediately due and payable and our revolving credit facility being terminated. The credit agreement also contains certain customary covenants, including financial covenants. The revolving credit facility financial covenants require Ingevity to maintain on a consolidated basis a maximum total net leverage ratio of 4.0 to 1.0 (which may be increased to 4.5 to 1.0 under certain circumstances) and a minimum interest coverage ratio of 3.0 to 1.0. As calculated per the credit agreement, our net leverage for the four consecutive quarters ended June 30, 2025 was 2.9, and our actual interest coverage for the four consecutive quarters ended June 30, 2025 was 5.0. We were in compliance with all covenants under the credit agreement at June 30, 2025.

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

(3) During 2024 and 2025, we took further steps to streamline our cost structure and improve profitability, resulting in additional restructuring charges for the three and six months ended June 30, 2025 of $9.7 million and $10.9 million, respectively.

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 historical annualized net sales. The repositioning included the closure of the

INGEVITY CORPORATION

Notes to the Condensed Consolidated Financial Statements

June 30, 2025

(Unaudited)

Performance Chemicals CTO refinery and manufacturing plant located in DeRidder, Louisiana (the “DeRidder Plant”), including the polyol production assets associated with the Advanced Polymer Technologies ("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 the 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 aggregate charges of approximately $365 million, excluding the CTO resale activity as described below, associated with the Performance Chemicals repositioning, consisting of approximately $255 million in asset-related charges, approximately $25 million in severance and other employee-related costs, and approximately $85 million in other restructuring costs, including decommissioning, dismantling and removal charges, and contract termination costs.

Through June 30, 2025, we have incurred $335.1 million associated with these actions, including $248.0 million of non-cash asset-related charges, and $87.1 million of charges to be settled in cash. As of June 30, 2025, $71.1 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 $110 million of cash charges, including approximately$10 to $15 million during the remainder of 2025.

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

Inventory Charges

The company believes the collective actions of workforce, operational, and regional business exits hindered our ability to dispose of the associated inventory on hand. As a result, we recorded zero and $2.5 million of non-cash, lower of cost or market, inventory charges for the three and six months ended June 30, 2024, respectively. These charges were made to adjust the carrying value of the affected inventory to its estimated realizable value, net of disposal costs, and are recorded to "Cost of sales" on the condensed consolidated statements 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 14 for more information.

CTO Resale Activity

The CTO resale activity described below ended in 2024 and no excess CTO volumes were on hand at June 30, 2025. The DeRidder Plant closure, and the corresponding reduction in 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. For the three and six months ended June 30 2024, we incurred $23.5 million and $50.0 million, respectively, of CTO resale losses, which are recorded as "Other (income) expense, net" on the condensed consolidated statements of operations.

On July 1, 2024, the CTO supply contract that resulted in these excess CTO volumes was terminated. As consideration for the termination of the CTO supply contract, we made cash payments totaling $100.0 million during 2024. The charge was recorded within "Other (income) expense, net" on the condensed 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.

Our North Charleston, South Carolina Performance Chemicals manufacturing plant has historically been co-located with a WestRock Company (“WestRock”) paper mill. In May 2023, WestRock announced that it would permanently cease operating its North Charleston paper mill by August 31, 2023 and notified us that it was terminating the shared services in accordance with our operating agreement. WestRock ceased production at their North Charleston paper mill in June 2023. During 2023, we executed a transition plan, which was completed in 2024, to separate certain critical operating services WestRock had historically provided to us such as steam, water and wastewater treatment. During the three and six months ended June 30, 2024, we incurred charges of $3.1 million and $3.6 million, respectively.

Restructuring and Other (Income) Charges, net Reserves

The following table shows a roll forward of restructuring reserves that will result in cash spending, the majority of which relate to the Performance Chemicals repositioning.

(3) Primarily foreign currency translation adjustments.

Note 12: Income Taxes

The effective tax rates, including discrete items, were as follows:

			Three Months Ended June 30,												Six Months Ended June 30,
			2025						2024						2025						2024
Effective tax rate (1)			(2.7)		%				15.2		%				(8.7)		%				16.4		%

_______________

(1) The decrease in the effective rate for the three and six months ended June 30, 2025, was primarily due to the goodwill impairment charge within our Advanced Polymers Technologies reportable segment, resulting in an overall book loss with a net tax liability.

We determine our interim tax provision using an Estimated Annual Effective Tax Rate methodology (“EAETR”). The EAETR is applied to the year-to-date ordinary income, exclusive of discrete items. The tax effects of discrete items are then included to arrive at the total reported interim tax provision.

The determination of the EAETR is based upon a number of estimates, including the estimated annual pre-tax ordinary income in each tax jurisdiction in which we operate. As our projections of ordinary income change throughout the year, the EAETR will change period-to-period. The tax effects of discrete items are recognized in the tax provision in the period they occur. Depending on various factors, such as the item’s significance in relation to total income and the rate of tax applicable in the jurisdiction to which it relates, discrete items in any quarter may materially impact the reported effective tax rate. As a global enterprise, our tax expense may be impacted by changes in tax rates or laws, the finalization of tax audits and reviews, as well as other factors. As such, there may be significant volatility in interim tax provisions.

(1) See Note 11 for further information. For the three and six months ended June 30, 2024, the charge includes zero and $2.5 million of lower of cost or market charges associated with the Performance Chemicals repositioning. Amounts are included in "Cost of sales" on the condensed consolidated statements of operations.

(2) See Note 4 for further information.

(3) See Note 7 for further information.

(4) See Note 14 for further information.

(5) Decrease in EAETR for the three and six months ended June 30, 2025, as compared to June 30, 2024, primarily reflects a shift in the projected mix of earnings across jurisdictions with varying tax rates, most notably in the U.S. Additionally, the increase in U.S. taxable income in 2025 is driving an increased benefit from the foreign-derived intangible income deduction as compared to 2024. The EAETR tax percentage shown for three and six months ended June 30, 2024 may not precisely recalculate due to rounding.

At June 30, 2025 and December 31, 2024, we had deferred tax assets of $12.0 million and $11.0 million, respectively, resulting from certain historical net operating losses from our Brazil and U.S. state tax credits for which a valuation allowance has been established. The ultimate realization of these deferred tax assets depends on the generation of future taxable income during the periods in which these net operating losses and tax credits are available to be used. In evaluating the realizability of these deferred tax assets, we consider projected future taxable income and tax planning strategies in making our assessment. As of June 30, 2025, we cannot objectively assert that these deferred tax assets are more likely than not to be realized and therefore

22

we have maintained a valuation allowance. We intend to continue maintaining a valuation allowance on these deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. A release of all or a portion of the valuation allowance could be possible if we determine that sufficient positive evidence becomes available to allow us to reach a conclusion that the valuation allowance will no longer be needed. A release of the valuation allowance would result in the recognition of certain deferred tax assets and a reduction to income tax expense for the period the release is recorded. However, the exact timing and amount of the valuation allowance release are subject to change based on the level of profitability that we are able to actually achieve.

Pillar Two, released by the Organisation for Economic Cooperation and Development (OECD), went into effect on January 1, 2024. Pillar Two’s intent is to create a 15% global minimum tax for all jurisdictions in which multinational enterprises operate. To date, fourteen of our reporting jurisdictions have enacted final legislation adopting Pillar Two. While we do not anticipate that this legislation will have a material impact on our tax provision or effective tax rate, we continue to monitor evolving tax legislation in the jurisdictions in which we operate. No tax impacts of Pillar Two were recorded for the quarter ended June 30, 2025.

Note 13: Commitments and Contingencies

Legal Proceedings

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

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

We disagree with the verdict, including the court’s application of the law and entry of judgment. Therefore, on March 13, 2024, we appealed the verdict as well as the U.S. District Court’s November 2020 dismissal of our patent infringement claims against BASF. Ingevity believes in the strength of its intellectual property and the merits of its position and intends to pursue all legal relief available to challenge these outcomes in the Delaware Proceeding. Final resolution of these appeals could take up to 12 months.

As of June 30, 2025, nothing has occurred in the post-trial proceedings to warrant any change to our conclusions as disclosed within our Annual Report on Form 10-K for the year ended December 31, 2024. The full amount of the trebled jury's verdict, $85.0 million, is accrued in "Accrued expenses" on the condensed consolidated balance sheets as of June 30, 2025 and the charge was included within "Other (income) expense, net" on the condensed consolidated statements of operations for the year ended December 31, 2021. In addition, as a result of the judgment being entered on May 18, 2023, we have started accruing for post-judgment interest at the legally mandated interest rate. We expect that final resolution of these appeals will be complete within twelve months of the balance sheet date and, as a result, have reclassified the full amount of the verdict and post-judgment interest accrued to "Current liabilities." As of June 30, 2025 and December 31, 2024, the total amount accrued, inclusive of post-judgement interest, was $93.4 million and $91.4 million, respectively. The amount of any liability we may ultimately incur could be more or less than the amount accrued.

Note 14: Segment Information

Ingevity’s reportable segments are (i) Performance Materials ("PM"), (ii) Performance Chemicals ("PC"), and (iii) Advanced Polymer Technologies ("APT"). Our reportable 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. Segment EBITDA is the primary measure used by the chief operating decision maker ("CODM"), the CEO and President of Ingevity, to evaluate the performance of and allocate resources among our reportable segments. The CODM utilizes Segment EBITDA for each reportable segment in the annual budgeting and forecasting process. Segment EBITDA enables the CODM to compare each business and make informed and consistent resource allocation decisions.

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

Introduction

Management’s discussion and analysis of Ingevity Corporation's (“Ingevity,” “the company,” “we,” “us,” or “our”) financial condition and results of operations (“MD&A”) is provided as a supplement to the Condensed Consolidated Financial Statements and related notes included elsewhere herein to help provide an understanding of our financial condition, changes in financial condition and results of our operations. The following discussion should be read in conjunction with Ingevity’s consolidated financial statements as of and for the year ended December 31, 2024, filed on February 19, 2025, with the Securities and Exchange Commission ("SEC") as part of the company's Annual Reporting on Form 10-K ("2024 Annual Report") and the unaudited interim Condensed Consolidated Financial Statements and notes to the unaudited interim Condensed Consolidated Financial Statements, which are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

All references to notes (herein referred to as "Note") in this section refer to the notes accompanying the Condensed Consolidated Financial Statements included in Item 1 within this Form 10-Q.

Investors are cautioned that the forward-looking statements contained in this section and other parts of this Quarterly Report on Form 10-Q involve both risk and uncertainty. Several important factors could cause actual results to differ materially from those anticipated by these statements. Many of these statements are macroeconomic in nature and are, therefore, beyond the control of management. See "Cautionary Statements About Forward-Looking Statements" below and at the beginning of our 2024 Annual Report.

Cautionary Statements Regarding Forward-Looking Statements

This section and other parts of this Quarterly Report on Form 10-Q contain forward-looking statements, within the meaning of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the Private Securities Litigation Reform Act of 1995 that reflect our current expectations, beliefs, plans or forecasts with respect to, among other things, future events and financial performance. Forward-looking statements are often characterized by words or phrases such as “may,” “will,” “could,” “should,” “would,” “anticipate,” “estimate,” “expect,” “outlook,” “project,” “intend,” “plan,” “believe,” “target,” “prospects,” “potential” and “forecast,” and other words, terms and phrases of similar meaning. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. We caution readers that a forward-looking statement is not a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statement. Such risks and uncertainties include, among others, those discussed in Part I, Item 1A. Risk Factors of our 2024 Annual Report, as well as in our unaudited Condensed Consolidated Financial Statements, related notes, and the other information appearing elsewhere in this report and our other filings with the SEC. We do not intend, and undertake no obligation, to update any of our forward-looking statements after the date of this report to reflect actual results or future events or circumstances. Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. In addition to any such risks, uncertainties and other factors discussed elsewhere herein, risks, uncertainties and other factors that could cause or contribute to actual results differing materially from those expressed or implied by the forward-looking statements include, but are not limited to the following:

•the anticipated timing, charges, costs and results of any current or future repositioning of our Performance Chemicals segment, including the oleo-based product refining transition and the closure of our plants in DeRidder, Louisiana and Crossett, Arkansas may differ materially from our estimates due to events that may occur as a result of, or in connection with, such repositioning efforts;

•our announced review of strategic alternatives for the industrial specialties product line and North Charleston, South Carolina crude tall oil (“CTO”) refinery may not result in a transaction and any transaction entered into may not yield the expected results or benefits;

•we may be adversely affected by general global economic, geopolitical, and financial conditions beyond our control, including inflation, the Russia-Ukraine war, and the conflict in the Middle East;

•leadership transitions within our organization;

•we are exposed to risks related to our international sales and operations, including changes in tariffs;

•adverse conditions in the automotive market have and may continue to negatively impact demand for our automotive carbon products;

28

•if more stringent air quality standards worldwide are not adopted, our growth could be impacted;

Overview

Ingevity Corporation provides products and technologies that purify, protect, and enhance the world around us. Through a diverse team of talented and experienced people, we develop, manufacture, and bring to market solutions that are largely renewably sourced and help customers solve complex problems while making the world more sustainable. Our products are used in a variety of demanding applications, including adhesives, agrochemicals, asphalt paving, bioplastics, coatings, elastomers, lubricants, 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 and Updates

Measurement Alternative Investments

During the second quarter of 2025, the company identified a trigger event indicating that an investment being accounted for under the measurement alternative may be impaired. For the three and six months ended June 30, 2025, the company recognized an impairment of $2.5 million recorded in "Other (income) expense, net" on the condensed consolidated statements of operations.

Goodwill Impairment Charge - Advanced Polymer Technologies

During the second quarter of 2025, the announcements and subsequent modifications of international tariffs escalated global trade tensions and contributed to increased consumer uncertainty, which negatively impacted parts of our businesses, particularly Advanced Polymer Technologies (“APT”). As a result, we conducted an analysis of the APT reporting unit’s goodwill, intangible assets, and long-lived assets. This analysis incorporated revised expectations regarding the pace and strength of industrial demand recovery in key markets. In addition, the macroeconomic changes experienced during the quarter contributed to unfavorable movements in key valuation inputs, including an increase in the risk-free rate used in calculating the discount rate.

Our analysis included significant assumptions such as the revenue growth rate, earnings before interest, taxes, depreciation, and amortization ("EBITDA") margin, and discount rate, which are judgmental. Variations in any assumptions could result in materially different calculations of fair value.

29

Based on the results of the quantitative analysis, we concluded that the carrying value of the APT reporting unit exceeded its fair value. As a result, we recorded a non-cash goodwill impairment charge of $183.8 million, representing all of the goodwill associated with the APT reporting unit. The charge is included within Goodwill impairment charge on the condensed consolidated statements of operations for the three and six months ended June 30, 2025. 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.

One Big Beautiful Bill

On July 4, 2025, the President signed into law the One Big Beautiful Bill ("OBBB"), which includes a comprehensive tax reform package that significantly modifies U.S. federal tax policy. We are currently evaluating the impacts of the OBBB, with preliminary observations indicating a notable impact on cash taxes due to the ability to accelerate deductions. We currently expect the OBBB will have minimal impact to our effective tax rate for 2025.

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 historical annualized net sales. The repositioning included the closure of the Performance Chemicals CTO refinery and manufacturing plant located in DeRidder, Louisiana (the “DeRidder Plant”), including the polyol production assets associated with the Advanced Polymer Technologies ("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 the 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 aggregate charges of approximately $365 million, excluding the CTO resale activity as described below, associated with the Performance Chemicals repositioning, consisting of approximately $255 million in asset-related charges, approximately $25 million in severance and other employee-related costs, and approximately $85 million in other restructuring costs, including decommissioning, dismantling and removal charges, and contract termination costs.

Through June 30, 2025, we have incurred $335.1 million associated with these actions, including $248.0 million of non-cash asset-related charges, and $87.1 million of charges to be settled in cash. As of June 30, 2025, $71.1 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 $110 million of cash charges, including approximately$10 to $15 million during the remainder of 2025.

30

Inventory Charges

The company believes the collective actions of workforce, operational, and regional business exits hindered our ability to dispose of the associated inventory on hand. As a result, we recorded zero and $2.5 million of non-cash, lower of cost or market, inventory charges for the three and six months ended June 30, 2024, respectively. These charges were made to adjust the carrying value of the affected inventory to its estimated realizable value, net of disposal costs, and are recorded to "Cost of sales" on the condensed consolidated statements 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 14 for more information.

CTO Resale Activity

The CTO resale activity described below ended in 2024 and no excess CTO volumes were on hand at June 30, 2025. The DeRidder Plant closure, and the corresponding reduction in 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. For the three and six months ended June 30 2024, we incurred $23.5 million and $50.0 million, respectively, of CTO resale losses, which are recorded as "Other (income) expense, net" on the condensed consolidated statements of operations.

On July 1, 2024, the CTO supply contract that resulted in these excess CTO volumes was terminated. As consideration for the termination of the CTO supply contract, we made cash payments totaling $100.0 million during 2024. The charge was recorded within "Other (income) expense, net" on the condensed 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.

Expected Savings and Impact

The Performance Chemicals repositioning, which began in November 2023, is 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 historical annualized net sales. For the three and six months ended June 30, 2025, we realized cash savings of approximately $11 million and $19 million, including $8 million and $14 million in Cost of sales, $3 million and $4 million in Selling, general, and administrative expenses, and zero and $1 million in Research and technical expenses, respectively.

Since November of 2023, we have realized total cash savings of approximately $103 million, including $82 million in Cost of sales, $16 million in Selling, general, and administrative expenses, and $5 million in Research and technical expenses, respectively. All cash savings have been realized as of June 30, 2025.

These cash savings have been derived from headcount reductions, plant operating efficiencies, and reduced supply chain costs. Collectively, these savings have been realized in the following financial statement captions: approximately 70-80 percent in Cost of sales, approximately 15-25 percent in Selling, general, and administrative expenses, and approximately 5 percent in Research and technical expenses, all presented on our condensed consolidated statements of operations.

In addition to the cash savings, we have realized savings of approximately $12 million in lower full year depreciation and intangible amortization expenses, respectively. All savings have been realized as of June 30, 2025.

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

Q2 2025 Performance Summary

Net sales declined primarily due to reduced performance in the Performance Chemicals segment, specifically within the road technologies and industrial specialties product lines. The decrease in industrial specialties sales was largely driven by strategic repositioning efforts aimed at reducing exposure to lower-margin end-use markets, resulting in an estimated $5 million reduction in quarterly sales. Additionally, unusually wet weather across much of the U.S. delayed road construction projects, negatively impacting the road technologies line. Further contributing factors included weaker customer demand, that accelerated toward the end of the quarter as a result of indirect tariff impacts within the Advanced Polymer Technologies reportable segment.

Net sales

The table below shows the 2025 Net sales and variances from 2024:

									Change vs. prior year

Performance Materials

Q2 2025 Performance Summary

Performance Materials Net sales decreased two percent compared to the prior year quarter. Sales in North America was offset by declines in Europe and Asia, excluding China where sales were flat year over year. Europe’s decline was attributed to tariff related uncertainty and the decline in Asia, excluding China, was due to timing of customer orders which benefited Q2 last year. Segment EBITDA for Performance Materials decreased $5.1 million or six percent, and Segment EBITDA margin declined to 50.1 percent. Segment EBITDA declined due to lower Net sales, investments in innovation, and one-time employee compensation costs.

Performance Chemicals

Q2 2025 Performance Summary

Performance Chemicals Net sales decreased $17.6 million (nine percent) compared to the prior year quarter, primarily as a result of our repositioning actions. Approximately $5 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 primarily due to wet weather across much of the U.S. that delayed road construction projects, impacting our road technologies product line, and weakness in industrial demand within our industrial specialties product line. Segment EBITDA improved $22.7 million compared to the prior year quarter, reflecting the positive impact of repositioning actions, including benefits from cost savings actions and lower raw material costs, primarily CTO.

The decrease of $69.6 million in 2025 was driven by a volume decline of $78.6 million (24 percent), as a result of a decrease in industrial specialties ($64.1 million) and road technologies ($14.5 million). This was partially offset by favorable pricing and sales mix of $8.4 million (three percent), attributable to an increase in industrial specialties ($5.0 million) and road technologies ($3.4 million). Net sales was also impacted by favorable foreign currency exchange of $0.6 million (zero percent).

Segment EBITDA. The increase of $33.0 million in 2025 was driven by lower manufacturing costs of $20.4 million, primarily due to lower cost CTO, LIFO liquidation benefit of $10.8 million, favorable pricing and sales mix of $8.4 million,

37

lower SG&A of $3.2 million, which benefited from the Performance Chemicals repositioning, and decreased foreign currency exchange and other charges of $2.6 million. The increase was partially offset by a volume decline of $12.4 million.

Advanced Polymer Technologies

Q2 2025 Performance Summary

Advanced Polymer Technologies Net sales decreased 10 percent compared to the prior year quarter primarily due to weaker customer demand, partly attributed to tariff uncertainty, and price concessions to address competitive pressures. Segment EBITDA decreased by 91 percent, primarily driven by a planned extended outage in the second quarter to install new boilers, and lower volumes stemming from tariff-related pressures.

Three Months Ended June 30, 2025 vs. 2024

Segment net sales. The decrease of $4.6 million in 2025 was driven by a volume decline of $4.7 million (10 percent), and unfavorable pricing and sales mix of $0.9 million (two percent). The decrease was partially offset by favorable foreign currency exchange of $1.0 million (two percent).

Segment EBITDA. The decrease of $8.9 million in 2025 was driven by increased manufacturing costs of $5.0 million, a volume decline of $1.8 million, increased SG&A of $1.0 million, unfavorable pricing and sales mix of $0.9 million, and increased foreign currency exchange and other charges of $0.2 million.

Six Months Ended June 30, 2025 vs. 2024

Segment net sales. The decrease of $10.4 million in 2025 was driven by a volume decline of $8.7 million (nine percent), and unfavorable pricing and sales mix of $2.0 million (two percent). The decrease was partially offset by favorable foreign currency exchange of $0.3 million (zero percent).

Segment EBITDA. The decrease of $5.9 million in 2025 was driven by a volume decline of $3.3 million, unfavorable pricing and sales mix of $2.0 million, increased SG&A of $1.2 million, and increased foreign currency exchange and other charges of $0.5 million. The decrease was partially offset by decreased manufacturing costs of $1.1 million.

Use of Non-GAAP Financial Measure - Adjusted EBITDA

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, goodwill impairment charge, acquisition and other-related (income) costs, litigation verdict charges, (loss) gain on strategic investments, loss on CTO resales, CTO supply contract termination charges, proxy contest 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 14 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 11 for more information.

(3) Refer to Note 7 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.

39

(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 through 2025 at amounts in excess of required CTO volumes. On July 1, 2024, the CTO supply contract that resulted in these excess CTO volumes was terminated. 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 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 three and six months ended June 30, 2024, the loss on CTO resales relates to the Performance Chemicals segment. Refer to Note 11 for more information.

(6) 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 4 for more information.

(7) Charges represent legal and other professional service fees as well as incremental proxy solicitation costs related to a proxy contest.

Adjusted EBITDA

Three and Six Months Ended June 30, 2025 vs. 2024

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

Current Full Year Company Outlook vs. Prior Year

We continue to closely monitor the evolving macroeconomic environment, including the impacts of recent tariffs and ongoing trade uncertainty. Despite these challenges, we are reaffirming our prior 2025 outlook for Net sales between $1.25 billion and $1.4 billion.

This guidance reflects current industry forecasts, which project a ~4 percent decline in North America light vehicle production when compared to 2024. As a result, we expect Net sales in our Performance Materials reportable segment to be similar to prior year.

In our Performance Chemicals reportable segment:

•The road technologies product line is expected to see modest growth over 2024.

•The industrial specialties product line is projected to deliver Net sales between $160 million and $200 million.

For our Advanced Polymer Technologies reportable segment, we expect Net sales to be down mid-to-high single digits versus the prior year, reflecting weaker end-market demand due to the impact of tariffs and continued competitive pressures.

Our Adjusted EBITDA outlook for 2025 has been revised to reflect improved profitability in Performance Chemicals and current forecasts of North America light vehicle production. We expect Adjusted EBITDA to be between $390 million and $415 million.

Should the forecasted ~4 percent reduction in North America light vehicle production versus 2024 materialize, we anticipate EBITDA in our Performance Materials reportable segment will decline compared to the prior year. However, we expect to maintain Performance Materials segment EBITDA margins of around 50 percent, supported by improved pricing and continued operational efficiencies.

In our Performance Chemicals reportable segment, we expect segment EBITDA to improve, driven by:

•Modest revenue growth in our road technologies product line,

•Lower CTO input costs, and

•The benefits of successfully executed repositioning actions.

We anticipate Performance Chemicals segment EBITDA margins to be in the high-single to low-double digits.

40

For our Advanced Polymer Technologies reportable segment, as a result of expected weaker end-market demand impacting volumes, segment EBITDA margins are expected to be in the mid-teens to-low twenty percent range.

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.

41

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 June 30, 2025, our undrawn capacity under our revolving credit facility was $400.0 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 11. 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 $76.9 million at June 30, 2025. 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 June 30, 2025, included $65.7 million held by our foreign subsidiaries. Cash and earnings of our foreign subsidiaries are generally used to finance our foreign operations and their capital expenditures. We believe that our foreign holdings of cash will not have a material adverse impact on our U.S. liquidity. If these earnings were distributed, such amounts could be subject to U.S. federal income tax at the statutory rate less the available foreign tax credits, if any, and could 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 9 for a summary of our outstanding debt obligations and revolving credit facility.

Other Potential Liquidity Needs

Share Repurchases

On July 25, 2022, our Board of Directors authorized the repurchase of up to $500.0 million of our common stock (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 Exchange Act.

During the three and six months ended June 30, 2025 and 2024, we repurchased no common stock. At June 30, 2025, $353.4 million remained unused under the 2022 Authorization.

Capital Expenditures

Projected 2025 capital expenditures are $50-70 million. We have no material commitments associated with these projected capital expenditures as of June 30, 2025.

Cash flow comparison of the Six Months Ended June 30, 2025 and 2024

			Six Months Ended June 30,
In millions			2025						2024
Net cash provided by (used in) operating activities			$	104.4					$	17.6
Net cash provided by (used in) investing activities			(14.3)						(34.1)
Net cash provided by (used in) financing activities			(74.0)						33.7

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 $104.4 million for the six months ended June 30, 2025.

Cash provided by operating activities for the six months ended June 30, 2025, when compared to the six months ended June 30, 2024, increased by $86.8 million. This increase was driven by a decrease in CTO resale cash outflows of $51.5 million, increased cash earnings of $2.1 million, a decrease in tax payments of $16.6 million, a net reduction in trade working capital of $19.8 million (including accounts receivable, inventory, and accounts payable), and lower cash interest paid of $5.1 million. Partially offsetting these cash inflows was increased employee compensation payments of $3.9 million, and increased spending on restructuring initiatives of $0.2 million.

Cash flows provided by (used in) investing activities

Cash used in investing activities in the six months ended June 30, 2025 was $14.3 million and was primarily driven by capital expenditures of $22.2 million. In the six months ended June 30, 2025 and 2024, capital spending included the base maintenance capital supporting ongoing operations, and growth and cost improvement spending. The decrease in Net cash used in investing activities when compared to the prior year period is primarily due to reduced capital expenditures of $12.5 million.

Capital expenditure categories			Six Months Ended June 30,
In millions			2025						2024
Maintenance			$	14.4					$	21.2
Safety, health and environment			5.0						2.0
Growth and cost improvement			2.8						11.5
Total capital expenditures			$	22.2					$	34.7

Cash flows provided by (used in) financing activities

Cash used in financing activities in the six months ended June 30, 2025, was $74.0 million and was primarily driven by payments on our revolving credit facility and other borrowings of $229.3 million, partially offset by proceeds from our revolving credit facility and other borrowings of $158.5 million.

Cash provided by financing activities in the six months ended June 30, 2024 was $33.7 million and was primarily driven by proceeds from our revolving credit facility and other borrowings of $120.2 million, partially offset by payments on our revolving credit facility and other borrowings of $83.1 million.

Critical Accounting Policies and Estimates

Our Condensed 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 described our accounting policies in Note 2 to our consolidated financial statements included in our 2024 Annual Report. 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. For a description of our critical accounting policies and estimates, refer to Part II, Item 7, Critical Accounting Policies and Estimates in our 2024 Annual Report. Our critical accounting policies have not substantially changed from those described in the 2024 Annual Report.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign currency exchange rate risk

We have foreign-based operations, primarily in Europe, South America and Asia, which accounted for approximately 24 percent of our net sales in the first six months of 2025. We have designated the local currency as the functional currency of our significant operations outside of the U.S. The primary currencies for which we have exchange rate exposure are the U.S. dollar versus the euro, the Japanese yen, the pound sterling, the Brazilian real, and the Chinese renminbi. In addition, certain of our domestic operations have sales to foreign customers. In the conduct of our foreign operations, we also make inter-company sales. All of this exposes us to the effect of changes in foreign currency exchange rates. Our earnings are therefore subject to change due to fluctuations in foreign currency exchange rates when the earnings in foreign currencies are translated into U.S. dollars. In some cases, to minimize the effects of such fluctuations, we use foreign exchange forward contracts to hedge firm and highly anticipated foreign currency cash flows. Our largest exposures are to the Brazilian real, the Chinese renminbi and the euro. A hypothetical 10 percent adverse change, excluding the impact of any hedging instruments, in the average Brazilian real, Chinese renminbi and euro to U.S. dollar exchange rates during the six months ended June 30, 2025, would have decreased our net sales and income before income taxes by approximately $7.8 million or one percent, and $2.7 million or two percent, respectively. Comparatively, a hypothetical 10 percent adverse change, excluding the impact of any hedging instruments, in the average Brazilian real, Chinese renminbi and euro to U.S. dollar exchange rates during the six months ended June 30, 2024, would have decreased our net sales and income before income taxes by approximately $8.4 million or one percent, and $2.9 million or one percent, respectively.

Interest rate risk

During the third quarter of 2024, we entered into a floating-to-fixed interest rate swap to convert a notional amount of $200.0 million of the variable, Secured Overnight Financing Rate ("SOFR") based interest component of our 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, which was 4.32 percent as of June 30, 2025, and in return are obligated to pay interest at a fixed rate of 3.84 percent until August 2026. The fair value of the interest rate swap was an asset (liability) of $(0.2) million and $0.6 million at June 30, 2025 and December 31, 2024, respectively.

As of June 30, 2025, approximately $485 million of our borrowings, adjusted for our $200.0 million floating-to-fixed interest rate swap, included a variable interest rate component. The weighted average interest rate associated with our variable interest rate borrowings was 5.69 percent for the period ended June 30, 2025. A hypothetical 100 basis point increase in the variable interest rate component of our borrowings for the six months ended June 30, 2025, would have increased our annual interest expense by approximately $4.8 million or seven percent. Comparatively, a 100 basis point increase in the variable interest rate component of our borrowings for the six months ended June 30, 2024, would have increased our annual interest expense by approximately $8.5 million or 10 percent.

Commodity price risk

A portion of our manufacturing costs includes purchased raw materials, which are commodities whose prices fluctuate as market supply and demand fundamentals change. Accordingly, product margins and the level of our profitability tend to fluctuate with the changes in these commodity prices.

44

Crude tall oil price risk

Our results of operations are directly affected by the cost of our raw materials, particularly CTO, which, excluding CTO resales, represented 7 percent and 16 percent of our condensed consolidated cost of sales for the six months ended June 30, 2025 and 2024, respectively. Raw material CTO spend was approximately $8 million and $18 million during the three and six months ended June 30, 2025. Comparatively, total raw material CTO spend was approximately $55 million and $111 million during the three and six months ended June 30, 2024. Pricing for CTO is driven by the limited supply of the product and competing demands for its use, both of which drive pressure on its price. Our gross profit and margins have been and could continue to be adversely affected by increases in the cost of CTO if we are unable to pass the increases on to our customers. Based on average pricing during the three and six months ended June 30, 2025, a hypothetical unhedged, unfavorable 10 percent increase in the market price for CTO would have increased our cost of sales by approximately $0.8 million (zero percent) and $1.8 million (zero percent), respectively, which we may not have been able to pass on to our customers. Comparatively, based on average pricing during the three and six months ended June 30, 2024, a hypothetical unhedged, unfavorable 10 percent increase in the market price for CTO would have increased our cost of sales by approximately $5.5 (two percent) and $11.1 million (two percent), respectively. The repositioning of the Performance Chemicals reportable segment and the termination of the long-term CTO supply contract have significantly reduced the company's volume requirements and exposure to CTO beginning in 2025.

Natural gas price risk

Natural gas, both direct and indirect, is our largest form of energy costs constituting approximately four percent of our cost of goods sold for the six months ended June 30, 2025. Increases in natural gas costs, unless passed on to our customers, would adversely affect our results of operations. If natural gas prices increase significantly, our business or results of operations may be adversely affected. We enter into certain derivative financial instruments to mitigate expected fluctuations in market prices and the volatility to earnings and cash flow resulting from changes to the pricing of natural gas purchases. Refer to Note 8 for more information on our natural gas price risk hedging program. For the three and six months ended June 30, 2025, a hypothetical, unhedged 10 percent increase in natural gas pricing would have resulted in an increase to cost of sales of approximately $0.7 million (28 basis points) and $1.6 million (39 basis points). Comparatively, for the three and six months ended June 30, 2024, a hypothetical, unhedged 10 percent increase in natural gas pricing would have resulted in an increase to cost of sales of approximately $0.9 million (33 basis points) and $1.9 million (36 basis points). As of June 30, 2025, we had 1.8 million mmBTUS (millions of British Thermal Units) in open natural gas derivative contracts, designated as cash flow hedges. As of June 30, 2025, open natural gas derivative contracts hedge a portion of forecasted transactions until September 2026. The fair value of the open natural gas derivative contracts was a net asset (liability) of $(0.5) million and $0.3 million as of June 30, 2025 and December 31, 2024, respectively.

Other market risks

Information about our other remaining market risks for the period ended June 30, 2025, does not differ materially from that discussed under Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk of our 2024 Annual Report.

45

ITEM 4.    CONTROLS AND PROCEDURES

a)    Evaluation of Disclosure Controls and Procedures 

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

As of June 30, 2025, Ingevity's Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), together with management, conducted an evaluation of the effectiveness of Ingevity's disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, the CEO and CFO concluded that these disclosure controls and procedures are effective at the reasonable assurance level.

b)    Changes in Internal Control over Financial Reporting 

There have been no changes in Ingevity's internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act) during the quarter ended June 30, 2025 that materially affected, or are reasonably likely to materially affect, Ingevity's internal control over financial reporting.

46

PART II.  OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

Information regarding certain of these matters is set forth below and in Note 13 – Commitments and Contingencies within the Condensed Consolidated Financial Statements.

ITEM 1A.    RISK FACTORS 

Part I, Item 1A, Risk Factors of our 2024 Annual Report sets forth information relating to important risks and uncertainties that could materially adversely affect the company’s business, financial condition and operating results. Except as set forth below, there have been no material changes in Ingevity's risk factors disclosed in Part I, Item 1A, Risk Factors of our 2024 Annual Report for the quarter ended June 30, 2025.

Recent changes to tariffs could negatively impact our business.

The U.S. government has imposed or announced new global tariffs, and is considering the imposition of additional tariffs. These new tariffs have resulted in retaliatory measures imposed, announced or under consideration by certain U.S. trading partners, most notably China. These changes to trade policy are expected to make it more difficult or costly for us to export our products and import raw materials. This in turn could require us to increase prices to our customers, which may reduce demand. Such demand reduction or inability to increase customer prices may negatively impact our profitability. The retaliatory tariff measures imposed by China, if not unwound, are expected to significantly lower our margin on Performance Materials and Performance Chemicals products sold from the United States into China. These tariff measures may also result in decreased demand for our customers’ products that incorporate our products, and adversely affect our financial condition and results of operations.

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

Disruptions to any of our manufacturing operations or other facilities due to natural disasters and extreme weather, such as a hurricane, tropical storm, earthquake, tornado, severe weather, flood or fire, or other unanticipated problems such as labor difficulties, pandemics, equipment failure, cyberattacks or other cybersecurity incidents, capacity expansion difficulties or unscheduled maintenance, planned or unplanned production slowdowns and shutdowns, turnarounds and outages, could cause operational disruptions of varied duration. Also, many of our production employees are governed by collective bargaining agreements (“CBAs”). The CBA at our Warrington, United Kingdom Advanced Polymer Technologies manufacturing facility with GMB Union is negotiated annually and the parties operate under the prior CBA until new terms are agreed. Further, the CBA at our Covington, Virginia Plant with the Covington Paperworkers Union Local 675, affiliated with the Association of Western Pulp and Paper Workers will expire on December 1, 2025. It is anticipated that the parties will begin contract renewal negotiations during the fourth quarter of 2025.

While the company has generally positive relations with its labor unions, there is no guarantee the company will be able to successfully negotiate new union contracts without work stoppages, labor difficulties or unfavorable terms. In addition, existing CBAs may not prevent a strike or work stoppage at the applicable plant.

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