2016 Business Outlook and Guidance Item FY16 Revenue $880M to $910M Adjusted EBITDA (1) $180M to $195M Effective tax rate 36-38% Capital expenditures $60M to $70M Free Cash Flow(2) $40M to $50M Net Debt Ratio(3) 2.0-2.5x (1) A reconciliation of Net Income to Adjusted EBITDA as projected for 2016 is not provided because we do not forecast Net Income as we cannot, without unreasonable effort, estimate or predict with certainty various components of Net Income. These components include additional separation costs associated with the Separation and further restructuring and other income (charges) incurred in 2016 as well as the related tax impacts of these items. 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. (2) Defined as Cash from Operations expected to range from $100M to $120M less Capital Expenditures. (3) Defined as Cash & cash equivalents, restricted investment less long term debt including capital lease obligation excluding deferred financing fees divided by annualized Adjusted EBITDA. 2nd Half Headwinds: • Planned maintenance outages at several U.S. facilities • Continued pressure in industrial specialties and oilfield • Historical slowness in Q4 Countered by: • Continued automotive carbon growth • Continued adoption of our pavement chemistries • Cost reduction on track for $25 million to $30 million 9

Appendix 11

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. These financial measures are not meant to be considered in isolation or as a substitute for the most directly comparable financial measure calculated in accordance with GAAP. The company believes these non-GAAP measures provide 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 and projected future results. Ingevity uses the following non-GAAP measures, inclusive of pro forma adjustments: Adjusted earnings (loss) is defined as net income (loss) attributable to Ingevity stockholders plus restructuring and other (income) charges, separation costs, and the income tax expense (benefit) on those items. Diluted adjusted earnings (loss) per share is defined as diluted earnings (loss) per common share attributable to Ingevity stockholders plus restructuring and other (income) charges per share, separation costs per share, and the income tax expense (benefit) per share on those items. Adjusted EBITDA is defined as net income (loss) plus provision for income taxes, interest expense, depreciation and amortization, separation costs and restructuring and other (income) charges. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by Net Sales Segment EBITDA is defined as segment operating profit plus depreciation and amortization. Segment EBITDA Margin is defined as Segment EBITDA divided by Net Sales. The Company also uses the above financial measures as the primary measures of profitability used by managers of the business and its segments. These non-GAAP financial measures are 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. Reconciliations of these non-GAAP financial measures are set forth within the following pages. 12
