Recast Historical Segment Information and certain Non-GAAP Financial Measures (Unaudited)
Beginning with our 2025 Form 10-K, Ingevity will remove Corporate and other costs from our Segment Operating Results, which are recorded within "Selling, general, and administrative expenses" on our Consolidated Statements of Operations. These costs are associated with corporate administrative functions (e.g., executive office, corporate finance, legal, human resources) and other compliance costs to operate as a NYSE listed entity. Additionally, these costs are managed at a corporate level and not directly attributable to our reportable segments. Reporting these costs separately will provide greater transparency into our segment results and cost structure.
Ingevity is providing, within this exhibit, unaudited recast Segment Operating Results and Adjusted EBITDA for continuing operations, a Non-GAAP Financial Measure, for the years ended December 31, 2025, 2024 and 2023 as well as the three month periods ended March 31, 2025 and 2024, June 30, 2025 and 2024, September 30, 2025 and 2024, and December 31, 2025 and 2024, that reflect the Corporate and other costs removed from our Segment Operating Results. These reporting changes have been retrospectively applied for all periods presented.
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.
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, goodwill impairment charges, long lived asset impairment charge, acquisition and other-related (income) costs, litigation verdict charges, (gain) loss on strategic investments, proxy contest charges, portfolio alignment costs, and pension and postretirement settlement and curtailment (income) charges, net.
