Management Change/Compensation, Changes in Control (Form 8-K)

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On August 17, 2026, the Compensation Committee of the Board of Directors (the "Compensation Committee") of Revelation Biosciences, Inc. (the "Company") approved grants of restricted shares of the Company's common stock (the "Restricted Stock Awards"), including to James Rolke, the Company's Chief Executive Officer, and Chester S. Zygmont, III, the Company's Chief Financial Officer, pursuant to the Revelation Biosciences, Inc. Amended and Restated 2021 Equity Incentive Plan (the "2021 Plan"). The Restricted Stock Awards were granted effective August 17, 2026.

Mr. Rolke received a Restricted Stock Award covering 208,076 shares of the Company's common stock, and Mr. Zygmont received a Restricted Stock Award covering 208,073 shares of the Company's common stock.

Subject to each executive's continued service with the Company or one of its subsidiaries through the applicable vesting date, each Restricted Stock Award will vest in four equal 25% tranches in accordance with the following:

(i) for the first tranche, upon the earlier occurrence of the Company achieving a market capitalization of $30 million for twenty (20) consecutive trading days or the second anniversary of the grant date;

(ii) for the second tranche, upon the earlier occurrence of the Company achieving a market capitalization of $60 million for twenty (20) consecutive trading days or the second anniversary of the grant date;

(iii) for the third tranche, upon the earlier occurrence of the Company achieving a market capitalization of $90 million for twenty (20) consecutive trading days or the fourth anniversary of the grant date; and

(iv) for the fourth tranche, upon the earlier occurrence of the Company achieving a market capitalization of $120 million for twenty (20) consecutive trading days or the fourth anniversary of the grant date.

For these purposes, market capitalization is determined by multiplying the closing sale price of the Company's common stock on the principal exchange by the number of shares of common stock outstanding as of the close of business on that trading day.

The Restricted Stock Awards will become fully vested immediately before (and contingent upon the consummation of) a Change in Control (as defined in the 2021 Plan), except as otherwise provided in an individual agreement between the Company and the applicable executive. If the executive's service terminates due to death, by the Company without Cause (as defined in the 2021 Plan), or by the executive for Good Reason (as defined in the award agreement), the Restricted Stock Award will become fully vested and nonforfeitable. Unless otherwise provided in the 2021 Plan or an individual agreement, unvested shares will be forfeited upon a termination of service for any other reason, including for Cause, Disability, or Retirement (as such terms are defined in the 2021 Plan).

The Restricted Stock Awards are subject to the terms and conditions of the 2021 Plan and the Company's form of Restricted Stock Award Agreement. The Company's form of Restricted Stock Award Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The 2021 Plan was previously filed as Appendix A to Revelation Biosciences, Inc.'s definitive proxy statement filed with the Securities and Exchange Commission on June 9, 2025 and is incorporated by reference herein.
