Ingevity Corporation (NYSE:NGVT) today reported its financial results for the second quarter 2025.

Net sales of $365.1 million declined 7% primarily due to lower sales in the Performance Chemicals segment. Net loss of $146.5 million and diluted loss per share of $4.02 reflected solid earnings growth offset by a pre-tax non-cash goodwill impairment charge of $183.8 million ($5.03 per share) associated with the Advanced Polymer Technologies segment. This impairment was recorded as a result of an impact assessment of heightened global trade uncertainty due to tariff announcements during the quarter, which prompted reevaluation of prior assumptions regarding the pace and strength of industrial demand recovery in key markets.

Adjusted earnings increased 39% to $51.1 million and diluted adjusted earnings per share (EPS) increased 38% to $1.39. Adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) was $110.0 million, an increase of 9%, with adjusted EBITDA margin of 30.1%. The EBITDA improvement is primarily attributed to the successful execution of repositioning actions in the Performance Chemicals segment which resulted in reduced raw material costs and improved product mix.

"Our strong profitability, robust free cash flow and improved leverage this quarter demonstrate our successful execution as well as the strength and resilience of our business model," said David Li, president and CEO of Ingevity. "We are also advancing our portfolio evaluation with a focus on retaining and investing in businesses that leverage our core competencies and also allow us to continue driving sustainable growth and delivering best-in-class EBITDA margins."

Performance Materials

Performance Materials sales were down 2% to $153.9 million as higher sales in North America partially offset lower sales in Asia and Europe, attributable primarily to tariff uncertainty. Segment EBITDA was down 6% to $77.1 million from last year's record quarter as favorable regional mix partially offset investments in innovation to drive future growth and certain one-time employee compensation costs. Segment EBITDA margins were 50.1%.

Advanced Polymer Technologies

Sales in Advanced Polymer Technologies were down $4.6 million, or 10%, to $43.3 million primarily as a result of softening customer demand, which intensified late in the quarter due to indirect impacts from tariffs, particularly in Europe. Segment EBITDA decreased from $9.8 million to $0.9 million largely due to the planned extended outage in Q2 to install new boilers noted last quarter, and lower volumes attributed to slow industrial demand and tariff-related pressures.

Performance Chemicals

Sales in Performance Chemicals were $167.9 million, down 10%. Industrial Specialties product line sales of $48.4 million were down 14% primarily due to the impact of repositioning actions implemented during 2024. Road Technologies product line sales of $119.5 million were down 7%, primarily due to unusually wet weather across parts of the U.S. that delayed road construction projects. Segment EBITDA was $32.0 million, an improvement of $22.7 million, reflecting the successful execution of repositioning actions, which included improved product mix from the exit of certain lower-margin end markets and lower raw material costs as the remaining high-cost crude tall oil inventory was consumed during the quarter.

Liquidity/Other

Operating cash flow was $79.0 million with free cash flow of $66.8 million, reflecting improved profitability, lower repositioning spend in Performance Chemicals and disciplined capital spend. There were no share repurchases for the quarter and $353.4 million remains available under the current $500 million Board authorization. Net leverage continued to improve to 3.0 times.

Full Year 2025 Guidance

Due to solid first half results and improved North America auto production forecasts, the Company is raising the low-end of adjusted EBITDA guidance with updated guidance of between $390 million and $415 million and maintaining sales guidance between $1.25 billion and $1.40 billion.

Use of non-GAAP financial measures: This press release includes certain non‐GAAP financial measures intended to supplement, not substitute for, comparable GAAP measures. Reconciliations of non‐GAAP financial measures to GAAP financial measures are provided within the Appendix to this press release. Investors are urged to consider carefully the comparable GAAP measures and the reconciliations to those measures provided. The company does not attempt to provide reconciliations of forward-looking non-GAAP guidance to the comparable GAAP measure because the impact and timing of the factors underlying the guidance assumptions are inherently uncertain and difficult to predict and are unavailable without unreasonable efforts. In addition, Ingevity believes such reconciliations would imply a degree of certainty that could be confusing to investors.

Ingevity Corporation

Non-GAAP Financial Measures

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

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

Ingevity uses the following non-GAAP measures:

Adjusted earnings (loss) is defined as net income (loss) plus restructuring and other (income) charges, net, goodwill impairment charges, acquisition and other-related (income) costs, pension and postretirement settlement and curtailment (income) charges, loss on CTO resales, CTO supply contract termination charges, (gain) loss on strategic investments, debt refinancing fees, litigation verdict charges, proxy contest charges, and the income tax expense (benefit) on those items, less the provision (benefit) from certain discrete tax items.

Diluted adjusted earnings (loss) per share is defined as diluted earnings (loss) per common share plus restructuring and other (income) charges, net, per share, goodwill impairment charges per share, acquisition and other-related (income) costs per share, pension and postretirement settlement and curtailment (income) charges per share, loss on CTO resales per share, CTO supply contract termination charges per share, (gain) loss on strategic investments per share, debt refinancing fees per share, litigation verdict charge per share, proxy contest charges per share and the income tax expense (benefit) per share on those items, less the provision (benefit) from certain discrete tax items per share.

Adjusted EBITDA is defined as net income (loss) plus interest expense, net, provision (benefit) for income taxes, depreciation, amortization, restructuring and other (income) charges, net, goodwill impairment charges, acquisition and other-related (income) costs, litigation verdict charges, (gain) loss 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.

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

Free Cash Flow is defined as the sum of net cash provided by (used in) the following items: operating activities less capital expenditures.

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

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

Ingevity's management also uses the above financial measures as the primary measures of profitability and liquidity of the business. In addition, Ingevity believes Adjusted EBITDA and Adjusted EBITDA Margin are useful measures because they exclude the effects of financing and investment activities as well as non-operating activities.

GAAP Reconciliation of 2025 Adjusted EBITDA Guidance

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; litigation verdict charges; additional pension and postretirement settlement and curtailment (income) charges; and revisions due to legislative tax rate changes. Additionally, discrete tax items could drive variability in our projected effective tax rate. All of these components could significantly impact such financial measures. Further, in the future, other items with similar characteristics to those currently included in adjusted EBITDA, that have a similar impact on the comparability of periods, and which are not known at this time, may exist and impact adjusted EBITDA.

________________
(1)	We regularly perform strategic reviews and assess the return on our operations, which sometimes results in a plan to restructure the business. These costs are excluded from our reportable segment results; details of which are included in the table below. For the details of these costs between our reportable segments, see Segment Operating Results on page 2.

________________
(i) Amounts are recorded within Restructuring and other (income) charges, net on the condensed consolidated statement of operations.
(ii) For information on our Workforce reductions and other, Performance Chemicals' repositioning, and North Charleston plant transition costs please refer to Note 15, Restructuring and Other (Income) Charges, net, in the Notes to the Consolidated Financial Statements included in the Company's Form 10-K for the year ended December 31, 2024, filed on February 19, 2025. Updates will be provided in subsequent filings of the Company's Form 10-Q in 2025.

(2)	During the second quarter of 2025, the company concluded that the carrying value of the Advanced Polymer Technologies reporting unit exceeded its fair value, resulting in a non-cash goodwill impairment charge. During the second quarter of 2024, the company concluded that the carrying value of the Performance Chemicals reporting unit exceeded its fair value, resulting in a non-cash goodwill impairment charge.
(3)	Charges represent (gains) losses incurred to complete and integrate acquisitions and other strategic investments. Charges may include the expensing of the inventory fair value step-up resulting from the application of purchase accounting for acquisitions and certain legal and professional fees associated with the completion of acquisitions and strategic investments. For the details of these costs between our reportable segments, see Segment Operating Results on page 2.
(4)	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, the purchases under the CTO supply contract ended effective June 30, 2024. The CTO resale activity described above ended in 2024.
(5)	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.
(6)	Charges represent legal and other professional service fees as well as incremental proxy solicitation costs related to a proxy contest.
(7)	Income tax impact of non-GAAP adjustments is the summation of the calculated income tax charge related to each pre-tax non-GAAP adjustment. The non-GAAP adjustments relate primarily to adjustments in the United States. As such, the income tax effect is calculated using the statutory tax rates of 21% for the United States and approximately 2.5% for state and local taxes, applied to the non-GAAP adjustments.
(8)	Represents certain discrete tax items such as excess tax benefits on stock compensation and impacts of legislative tax rate changes.
(9)	The average number of shares outstanding used in the three and six months ended 2025 diluted adjusted earnings (loss) per share computation (Non-GAAP) includes 0.2 and 0.3 million diluted shares, respectively. The average number of shares outstanding used in the three and six months ended 2024 diluted adjusted earnings (loss) per share computation (Non-GAAP) includes 0.2 million diluted shares, respectively. This number of shares differs from the average number of shares outstanding used in diluted earnings (loss) per share computations (GAAP) as we had a net loss on a GAAP basis.

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