Ingevity Corporation (the “Registrant” or “Company”) filed a Registration Statement on Form S-8 (File No. 333-211430) with the Securities and Exchange Commission (the “Commission”) on May 18, 2016 (the “Original Registration Statement”) registering 4,000,000 shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), issuable under the Ingevity Corporation 2016 Omnibus Incentive Plan (the “2016 Plan”).

On April 30, 2025, the Company’s stockholders approved the Ingevity Corporation 2025 Omnibus Incentive Plan (the “2025 Plan”), and on such date (the “Effective Date”) the 2025 Plan became effective. Following the Effective Date, no further awards were authorized for grant under the 2016 Plan. The total number of shares of Common Stock authorized for issuance under the 2025 Plan includes, in addition to 425,000 new shares of Common Stock (registered on a new registration statement on Form S-8 filed contemporaneously with this Post-Effective Amendment), (a) shares of Common Stock that remain available under the 2016 Plan immediately prior to the Effective Date, and (b) shares of Common Stock underlying any equity awards previously granted under the 2016 Plan as of the Effective Date that, on or after the Effective Date, are forfeited, terminated, expire or lapse without being exercised, or any such awards that are settled for cash (collectively, the shares of Common Stock described in clauses (a) and (b) above, the “Rollover Shares”). On and after the Effective Date, the Rollover Shares may be issued under the 2025 Plan.

The Company is filing this Post-Effective Amendment No. 1 to the Original Registration Statement (the “Post-Effective Amendment”) pursuant to Item 512(a)(1)(iii) of Regulation S-K to cover the offering of the Rollover Shares under the 2025 Plan. No additional shares of Common Stock are being registered hereby.
