1. Organization and Basis of PresentationRevelation Biosciences, Inc. (collectively with its wholly-owned subsidiaries, the “Company” or “Revelation”), formerly known as Petra Acquisition, Inc. (“Petra”), was incorporated in Delaware on November 20, 2019. The Company was formed for the purpose of entering into a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or similar business combination with one or more businesses or entities. On January 10, 2022 (the “Closing Date”) the Company consummated its business combination, with Revelation Biosciences Sub, Inc. (“Old Revelation” or “Revelation Sub”), the Company's wholly owned subsidiary (the “Business Combination”). Since the Business Combination, the Company is a clinical-stage biopharmaceutical company and has been focused on the development and commercialization of immunologic therapeutics and diagnostics.The Business Combination was accounted for as a reverse recapitalization with Revelation Sub as the accounting acquirer and Petra as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the audited consolidated financial statements represents the accounts of Revelation Sub as if Revelation Sub is the predecessor to the Company. The common stock and net loss per share, prior to the Merger, have been retroactively restated as common stock and net loss per share reflecting the exchange ratio established in the Business Combination (the “Common Stock Exchange Ratio”).Petra’s Common Stock, Public Warrants and Units were historically listed on the Nasdaq Capital Market under the symbols “PAIC,” “PAICW” and “PAICU,” respectively. On January 10, 2022, the Company’s units, common stock and warrants were listed on the Nasdaq Capital Market under the symbols “REVBU”, “REVB” and “REVBW”, respectively, (see Note 3).On January 13, 2023, the Company’s units were mandatorily separated into one share of common stock and one Public Warrant and ceased trading on the Nasdaq Capital Market.On January 30, 2023, the Company filed a Certificate of Amendment of the Third Amended and Restated Certificate of Incorporation (the “Certificate of Amendment”) reflecting the change in authorized shares of common stock from <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">100,000,000 to <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">500,000,000 and effecting a reverse stock split as of 12:01 a.m. Eastern Standard Time on February 1, 2023 with a ratio of 1-for-35 (the “Reverse Split”). As a result of the Reverse Split, every <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">35 shares of the Company’s issued and outstanding common stock automatically converted into <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">one share of common stock, without any change in the par value per share. No fractional shares will be outstanding following the Reverse Split. Any holder who would have received a fractional share of common stock will automatically be entitled to receive an additional fraction of a share of common stock to round up to the next whole share. In addition, effective as of the same time as the Reverse Split, proportionate adjustments were made to all then-outstanding equity awards and warrants with respect to the number of shares of common stock subject to such award or warrant and the exercise price thereof. Furthermore, the number of shares of common stock available for issuance under the Company’s equity incentive plans were proportionately adjusted for the Reverse Split ratio, such that fewer shares will be subject to such plans. All share numbers and preferred stock conversion numbers included herein have been retroactively adjusted to reflect the 1-for-35 Reverse Split. (See Note 10).The Company has incurred recurring losses since its inception, including a net loss of $<span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">10.8 million for the year ended December 31, 2022. As of December 31, 2022, the Company had an accumulated deficit of $<span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">25.3 million, a stockholders’ equity of $<span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">1.1 million and available cash and cash equivalents of $<span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">5.3 million. The Company expects to continue to incur significant operating and net losses, as well as negative cash flows from operations, for the foreseeable future as it continues to complete all necessary product development or future commercialization efforts. The Company has never generated revenue and does not expect to generate revenue from product sales unless and until it successfully completes development and obtains regulatory approval for REVTx-300, REVTx-100, REVTx-200, REVTx-99b, REVDx-501 or other product candidates, which the Company expects will not be for at least several years, if ever. Additionally, taking into consideration the net proceeds of approximately $<span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">14.0 million received in connection with the public offering completed in February of 2023, the Company does not anticipate that its current cash and cash equivalents balance will be sufficient to sustain operations within one year after the date that the Company’s audited financial statements for December 31, 2022 were issued, which raises substantial doubt about its ability to continue as a going concern.To continue as a going concern, the Company will need, among other things, to raise additional capital resources. The Company plans to seek additional funding through public or private equity or debt financings. The Company may not be able to obtain financing on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. If the Company is unable to obtain funding, it could be required to delay, reduce or eliminate research and development programs, product portfolio expansion or future commercialization efforts, which could adversely affect the Company’s business operations.The audited consolidated financial statements for December 31, 2022, have been prepared on the basis that the Company will continue as a going concern, and does not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the possible inability for the Company to continue as a going concern.The accompanying financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All inter-company transactions and balances have been eliminated in consolidation. Certain amounts previously reported in the financial statements have been reclassified to conform to the current year presentation. Such reclassifications did not affect net loss, stockholders’ deficit or cash flows.

On January 13, 2023, the Company’s units were mandatorily separated into one share of common stock and one Public Warrant and ceased trading on the Nasdaq Capital Market.

As a result of the Reverse Split, every 35 shares of the Company’s issued and outstanding common stock automatically converted into one share of common stock, without any change in the par value per share. No fractional shares are outstanding following the Reverse Split. Any holder who would have received a fractional share of common stock automatically received an additional fraction of a share of common stock to round up to the next whole share. In addition, effective as of the same time as the Reverse Split, proportionate adjustments were made to all then-outstanding equity awards and warrants with respect to the number of shares of common stock subject to such award or warrant and the exercise price thereof. Furthermore, the number of shares of common stock available for issuance under the Company’s equity incentive plans were proportionately adjusted for the Reverse Split ratio, such that fewer shares will be subject to such plans.

11. Stock-Based Compensation2020 Equity Incentive Plan and 2021 Equity Incentive PlanPrior to the Merger, Revelation Sub adopted the Revelation Biosciences, Inc. 2020 Equity Incentive Plan (the “2020 Plan”) on October 1, 2020 for the issuance of stock-based awards. There was a total of <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">13,154 shares that had been granted for RSU awards under the 2020 Plan. On the Closing Date of the Business Combination, the outstanding RSU awards from the 2020 Plan were exchanged for Rollover RSU awards and the 2020 Plan was cancelled and there are <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">no additional shares available for grant under the 2020 Plan.In January 2022, in connection with the Business Combination, the Board of Directors adopted the 2021 Equity Incentive Plan (the “2021 Plan”) and reserved <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">36,983 authorized shares of common stock the Company could issue. The 2021 Plan is administered by the Board of Directors. Vesting periods and other restrictions for grants under the 2021 Plan are determined at the discretion of the Board of Directors. Grants to employees, officers, directors, advisors, and consultants of the Company typically vest over one to four years. In addition, the number of shares of stock available for issuance under the 2021 Plan will be automatically increased each January 1, beginning on January 1, 2022, by <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">10% of the aggregate number of outstanding shares of our common stock from the first day of the preceding calendar year to the first day of the current calendar year or such lesser number as determined by our board of directors. On January 1, 2023, after effecting the Reverse Split the total shares available for issuance under the 2021 Equity Plan was increased to <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">68,288 authorized shares of common stock.Under the 2021 Plan, stock options and stock appreciation rights are granted at exercise prices determined by the Board of Directors which cannot be less than <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">100% of the estimated fair market value of the common stock on the grant date. Incentive stock options granted to any stockholders holding 10% or more of the Company's equity cannot be granted with an exercise price of less than <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">110% of the estimated fair market value of the common stock on the grant date and such options are not exercisable after five years from the grant date.As of December 31, 2022, there were <span style="font-size:10.0pt;font-family:"Times New Roman", serif;white-space:pre-wrap;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">58,707 shares available for future grant under the 2021 Plan.Restricted Stock UnitsAt the Closing Date of the Business Combination, all Revelation Sub RSU award holders received a Rollover RSU award in exchange for each RSU award of Revelation Sub that vest in accordance with the original terms of the award. The Company determined this to be a Type I modification but did not record any incremental stock-based compensation expense since the fair value of the modified awards immediately after the modification was not greater than the fair value of the original awards immediately before the modification.The Rollover RSU awards have time-based and milestone-based vesting conditions. Under time-based vesting conditions, the Rollover RSU awards vest quarterly over one year for grants to the Board of Directors and quarterly over four years or <span style="font-size:10.0pt;font-family:"Times New Roman", serif;background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">25% on the one year anniversary and the remainder vesting monthly thereafter for grants to officers, employees and consultants.

In determining the expected term of stock options, the Company uses the “simplified” method. Under this method, the expected term is presumed to be the midpoint between the average vesting date and the end of the contractual term. The risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of the stock options in effect at the time of the grants. The dividend yield assumption is based on the expectation of no future dividend payments by the Company. In addition to assumptions used in the Black-Scholes model, the Company reduces stock-based compensation expense based on actual forfeitures in the period that each forfeiture occurs.Stock-Based Compensation Expense<div style="font-size:10.0pt;font-family:"Times New Roman", serif;">For the years ended December 31, 2022 and 2021, the Company recorded stock-based compensation expense for the
