Ingevity Corporation (NYSE:NGVT) today reported its financial results for the first quarter of 2026.

The results and guidance in this release include non-GAAP financial measures. Additional information, including definitions and reconciliations to the most comparable GAAP measures, can be found in the section titled "Use of non‑GAAP financial measures." Unless otherwise stated, all comparisons below are made versus the same period in 2025 and are presented on a continuing operations basis.

Full Company Results

Net sales of $258.0 million increased 4% driven primarily by annual pricing actions in Performance Materials and Pavement Technologies and favorable foreign exchange. The company reported net income from continuing operations of $23.4 million and diluted earnings per share (EPS) of $0.65, which includes $22.7 million of pre-tax special charges, inclusive of a $16.2 million charge related to the reimbursement of legal fees payable to BASF as part of the final settlement of the outstanding litigation. Adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) was similar to the prior year at $91.5 million, as pricing actions and higher volume were offset by weaker operating performance in the Performance Chemicals Road Markings product line, and lower asset utilization in the Advanced Polymer Technology segment. Adjusted earnings increased to $41.4 million and diluted EPS was $1.15 compared to $37.0 million and $1.01 in the prior year. First quarter adjusted EBITDA margin was 35.5% compared to 36.8% in the prior year.

"I am proud of our team's strong execution in the face of macroeconomic volatility and rising energy costs. Closing both the Industrial Specialties and Road Markings divestitures early in the year was a significant achievement and enabled us to deploy $52 million in share repurchases ahead of our original plan. We are maintaining our full-year outlook and are encouraged by early trends and momentum at the start of the year," said Ingevity President and CEO, Dave Li.

Segment Results

Performance Materials

Performance Materials grew sales 6% across most regions to $155.4 million. The higher sales were driven by annual pricing actions, favorable mix as a shift in consumer preferences from battery electric vehicles to hybrids continued, and an increase in volume. Segment EBITDA was up 10% to $92.0 million driven by improved price and mix, higher volume, and higher plant utilization in the quarter to build inventory ahead of planned outages in the second quarter, which more than offset higher SG&A and other expenses. Segment EBITDA margin improved 230 basis points to 59.2% compared to 56.9% in the prior year.

Performance Chemicals

Performance Chemicals sales, which include the Road Markings product line divested on April 15, 2026, were $58.3 million, similar to the prior year. Pavement Technologies sales were flat, as improvements in price and mix were offset by lower volumes. Sales in Road Markings declined 10 percent, driven by continued competitive pressure impacting volumes, while pricing remained stable. Segment EBITDA of $0.6 million declined $5.2 million from the prior year driven primarily by lower plant utilization in Road Markings compared to the first quarter of 2025. Segment EBITDA margin was 1.0% compared to 9.8% in the prior year.

Advanced Polymer Technologies

Advanced Polymer Technologies sales of $44.3 million increased 5% as favorable foreign exchange and higher volume more than offset decline in price due to unfavorable mix. Segment EBITDA for the quarter was $7.6 million compared to $13.6 million in the prior year due primarily to an inventory build in the first quarter of 2025, in anticipation of a material planned outage in the second quarter 2025. Segment EBITDA margin was 17.2% compared to 32.2% in the prior year.

Corporate and Other

Corporate and other expenses, which are not included in segment financial results, were $8.7 million, similar to the prior year. Indirect costs associated with the divested Industrial Specialties product line were zero compared to $3.2 million in the first quarter of 2025 as approximately one third of the costs were eliminated and the remaining costs were allocated to the business segments.

Liquidity/Other Continuing and Discontinued Operations

First quarter operating cash flow was negative $2.0 million, a decrease of $27.4 million versus the same quarter in 2025 as the business reverted to its historical seasonality, resulting in negative free cash flow of $12.3 million. First quarter of 2026 reflects a typical cadence of cash outflow from Pavement Technologies given the seasonality of the business, and an inventory build in Performance Materials ahead of planned outages in the second quarter. In 2025, the first quarter had an outsized contribution from a working capital benefit of approximately $15 million primarily related to inventory management within the divested Industrial Specialties product line.

Share repurchases totaled $52 million for the first quarter, with approximately $246 million available capacity remaining under the company's current share repurchase authorization. Net leverage held steady at 2.6 times versus the fourth quarter of 2025 and is down from 3.3 times versus the same quarter last year.

Full Year 2026 Outlook:

The company reaffirms full year 2026 guidance updated for the recently announced divestiture of Road Markings. It expects full year 2026 net sales between $1.05 billion and $1.15 billion, adjusted EBITDA between $370 million and $395 million, and adjusted EPS of $4.70 to $5.20. Free cash flow is expected to be between $215 million and $245 million, excluding $113.2 million in the pre-tax litigation settlement paid to BASF. The company intends to utilize the strong free cash flow to reduce leverage to within our long-term target range of 2.0-2.5 times and return cash to shareholders in 2026. The 2026 outlook includes full year financial results for Advanced Polymer Technologies but excludes the divested Industrial Specialties product line for the full year and the Road Markings product line beginning April 15, 2026.

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 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) from continuing operations is defined as net income (loss) from continuing operations plus restructuring and other (income) charges, net, goodwill impairment charges, long lived asset impairment charge, acquisition and other-related (income) costs, pension and postretirement settlement and curtailment (income) charges, impairment of license agreement, debt refinancing fees, litigation charge, proxy contest charges, portfolio realignment costs, and the income tax expense (benefit) on those items, less the provision (benefit) from certain discrete tax items.

Diluted adjusted earnings (loss) from continuing operations per share is defined as diluted earnings (loss) from continuing operations per share plus restructuring and other (income) charges, net, per share, acquisition and other-related (income) costs per share, pension and postretirement settlement and curtailment (income) charges per share, impairment of license agreement per share, debt refinancing fees per share, litigation charge per share, proxy contest charges per share, portfolio realignment costs 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 from continuing operations is defined as net income (loss) from continuing operations plus interest expense, net, provision (benefit) for income taxes, depreciation, amortization, restructuring and other (income) charges, net, acquisition and other-related (income) costs, litigation charge, impairment of license agreement, proxy contest charges, portfolio realignment costs, and pension and postretirement settlement and curtailment (income) charges, net.

Total adjusted EBITDA is defined as Adjusted EBITDA from continuing operations and Adjusted EBITDA from discontinued operations.

Adjusted EBITDA margin from continuing operations is defined as Adjusted EBITDA from continuing operations divided by Net sales from continuing operations.

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 from continuing operations.

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

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 from continuing operations and Adjusted EBITDA Margin from continuing operations are useful measures because they exclude the effects of financing and investment activities as well as non-operating activities.

GAAP Reconciliation of 2026 Adjusted EBITDA Guidance

A reconciliation of net income to Adjusted EBITDA from continuing operations as projected for 2026 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 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 from continuing operations, that have a similar impact on the comparability of periods, and which are not known at this time, may exist and impact Adjusted EBITDA from continuing operations.
