Notes to the Condensed Consolidated Financial Statements

(Unaudited)

1. Organization and Basis of Presentation

Revelation Biosciences, Inc. (collectively with its wholly-owned subsidiaries, the “Company” or “Revelation”), formerly known as Petra Acquisition, Inc. (the “Company” or “Petra”(“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 entitiesentities. 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”). The Company is not limited to a particular industry or sector for purposes of consummating aSince the Business Combination. The Company is an early stage and emerging growth company and, as such,Combination, the Company is subject to alla clinical-stage biopharmaceutical company and has been focused on the development and commercialization of the risks associated with early stageimmunologic therapeutics and emerging growth companies.diagnostics.

AsThe 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 unaudited condensed consolidated financial statements represents the accounts of September 30, 2021,Revelation Sub as if Revelation Sub is the Company had not commenced any operations. All activity for the period from November 20, 2019 (Inception) through September 30, 2021 relatespredecessor to the Company’s formation, initial public offering (“Initial Public Offering”),Company. The common stock and search for an acquisition target, which is described below. The Company will not generate any operating revenues until afternet loss per share, prior to the completion of aMerger, have been retroactively restated as common stock and net loss per share reflecting the exchange ratio established in the Business Combination at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.(

2.725

The registration statement for the Company’s Initial Public Offering became effective on October 7, 2020. On October 13, 2020, the Company consummated the Initial Public Offering of 7,000,000 units (the “Units” and, with respect to the shares of common stock included in the Units sold, the “Public Shares”) at $10.00 per Unit, generating gross proceedsfor 1 share of $70,000,000, which is described in Note 3.Revelation Sub common stock (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).

Simultaneously withThe Company has incurred recurring losses since its inception, including a net loss of $6.6 million for the closingthree months ended March 31, 2022. As of the Initial Public Offering,March 31, 2022, the Company consummated the salehad an accumulated deficit of 3,150,000 warrants (the “Private Placement Warrants”) at$21.1 million, a pricestockholders’ deficit of $1.00 per Private Placement Warrant in a private placement$98,511 and available cash and cash equivalents of $7.2 million. The Company expects to Petra Investment Holdings, LLC, a Delaware limited liability company (the “Sponsor”), for gross proceeds of $3,150,000. The fundscontinue to incur significant operating and net losses, as well as negative cash flows from operations, for the Private Placement Warrants had been placed in our Trust account in anticipation offoreseeable 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-99a, REVTx-99b, REVDx-501 or other product candidates, which the exercise priorCompany expects will not be for at least several years, if ever. The Company does not anticipate that its current cash and cash equivalents balance will be sufficient to September 30, 2020.sustain operations within one year after the date that the Company’s unaudited financial statements for March 31, 2022 were issued, which raises substantial doubt about its ability to continue as a going concern.

Transaction costs amounted to $4,682,736, consisting of $4,366,980 of underwriting discounts ($2,911,260 of which payment is deferred) and $315,846 of professional fees, printing, filing, regulatory and other costs which have been charged to additional paid in capital upon completion of the Initial Public Offering.

Following the closing of the Initial Public Offering on October 13, 2020, an amount of $70,700,000 ($10.00 per Unit, plus $700,000 trust deposit premium) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”) which are to be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in any open-ended investment company that holds itself outTo continue as a money market fund selected by the Company meeting the conditions of Rule 2a-7 of the Investment Company Act of 1940, as amended (the “Investment Company Act”), as determined by the Company, until the earlier of: (i) the consummation of a Business Combination and (ii) the distribution of the funds in the Trust Account, as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the private warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance thatgoing 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 complete a Business Combination successfully.obtain financing on acceptable terms, or at all. The Company must complete a Business Combination having an aggregate fair market valueterms of at least 80% ofany financing may adversely affect the assets held in the Trust Account (as defined below) (excluding taxes payable on income earned on the Trust Account) at the time of the agreement to enter into an initial Business Combination. The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”).

The Company will provide its holders of the outstanding Public Shares (the “Public Stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.10 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income tax obligations and up to $250,000 per 12-month period for working capital requirements). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants.

The Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law,holdings or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Company’s Sponsor have agreed to vote their Founder Shares (See Notes 5 and 7), and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination and not to convert any shares in connection with a stockholder vote to approve a Business Combination or sell any shares to the Company in a tender offer in connection with a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or don’t vote at all.

The Sponsor has agreed (a) to waive their redemption rights with respect to their Founder Shares and Public Shares held by it in connection with the completion of a Business Combination, (b) to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to consummate a Business Combination, and (c) not to propose an amendment to the Amended and Restated Certificate of Incorporation that would affect a public stockholder’s ability to convert or sell their shares to the Company in connection with a Business Combination or affect the substance or timing of the Company’s obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

The Company will have until 12 months from the closing of the Initial Public Offering to complete a Business Combination (the “Combination Period”), which was extended as disclosed in Note 9.stockholders. If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equalobtain funding, it could be required to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Accountdelay, reduce or eliminate research and not previously released to the Company to pay franchise and income taxes, divided by the number of then outstanding Public Shares,development programs, product portfolio expansion or future commercialization efforts, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval ofcould adversely affect the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period.

In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below $10.10 per Public Share, except as to any claims by a third party who executed a valid and enforceable agreement with the Company waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Insiders will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Insiders will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.operations.

Liquidity

The accompanying unaudited condensed consolidated financial statements for March 31, 2022, have been prepared on the basis that the Company will continue as a going concern, which contemplates realizationand does not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and satisfyingclassification of liabilities inthat may result from the normal course of business. At September 30, 2021,possible inability for the Company had an accumulated deficit of approximately $6,604,000 and working capital deficiency of approximately $3,698,000. For the nine months ended September 30, 2021, the Company hadto continue as a loss from operations of approximately $2,155,000 and negative cash flows from operations of approximately $500,000.going concern.

Based on the funds received from the Initial Public Offering and funds available under borrowing arrangements management believes that the Company will have sufficient working capital and borrowing capacity to successfully complete the Business Combination. Over this time period, the Company will be using these funds for paying operational expenses, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

Emerging Growth Company

April 22, 2022. The Company is an “emerging growth company,”accompanying condensed consolidated balance sheet as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptionsMarch 31, 2022 has been derived from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.audited balance sheet at December 31, 2021 contained in the above referenced Form 8-K/A.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any sch election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of the condensed consolidated financial statementstatements in conformityaccordance with GAAP requires the Company’s management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities and disclosure ofreported, disclosures about contingent assets and liabilities, at the date of the financial statement and the reported amounts of revenuesexpenses. These estimates and expenses duringassumptions are based on the reporting period.

MakingCompany’s best estimates requires management to exercise significantand judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statement, which management considered in formulatingThe Company regularly evaluates its estimate, could change in the near term due to one or more future confirming events. Accordingly, theestimates and assumptions using historical and industry experience and other factors; however, actual results could differ significantlymaterially from those estimates.these estimates and could have an adverse effect on the Company’s condensed consolidated financial statements.

The Company accounts for its common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value.

Level 1 — Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable inputs for similar assets or liabilities. These include quoted prices for identical or similar assets or liabilities in active markets and overallotment upon completionquoted prices for identical or similar assets or liabilities in markets that are not active;

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the IPOassets or liabilities.

Warrant LiabilityLeases

The Company accountsdetermines if an arrangement is a lease at inception. Lease right-of-use assets represent the right to use an underlying asset for the Private Warrantslease term and lease liabilities represent the obligation to make lease payments arising from the lease. For operating leases with an initial term greater than 12 months, the Company recognizes operating lease right-of-use assets and operating lease liabilities based on the present value of lease payments over the lease term at the commencement date. Operating lease right-of-use assets are comprised of the lease liability plus any lease payments made and excludes lease incentives. Lease terms include options to renew or terminate the lease when the Company is reasonably certain that the renewal option will be exercised or when it is reasonably certain that the termination option will not be exercised. For an operating lease, if the interest rate used to determine the present value of future lease payments is not readily determinable, the Company estimates the incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in accordancesimilar economic environments. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for the development of the Company’s lead product candidates, REVTx-99a/b and lead diagnostic product, REVDx-501. Research and development costs are charged to expense as incurred. The Company records accrued expenses for estimated preclinical, clinical study and research expenses related to the services performed but not yet invoiced pursuant to contracts with research institutions, contract research organizations, and clinical manufacturing organizations that conduct and manage preclinical studies, clinical studies, research services, and development services on the guidance containedCompany’s behalf. Payments for these services are based on the terms of individual agreements and payment timing may differ significantly from the period in ASC 815 under which the Private Warrants do not meetservices were performed. Estimates are based on factors such as the criteria for equity treatmentwork completed, including the level of patient enrollment. The Company monitors patient enrollment levels and must be recorded as derivative liabilities. Accordingly,related activity to the Company classifiesextent reasonably possible and makes judgments and estimates in determining the Private Warrants as liabilities at their fair value and adjusts the Private Warrants to fair value ataccrued balance in each reporting period. This liabilityThe Company’s estimates of accrued expenses are based on the facts and circumstances known at the time. If the Company underestimates or overestimates the level of services performed or the costs of these services, actual expenses could differ from estimates. As actual costs become known, the Company adjusts accrued expenses. To date, the Company has not experienced significant changes in estimates of clinical study and development services accruals.

Patent Costs

Legal costs in connection with approved patents and patent applications are expensed as incurred, as recoverability of such expenditures is subjectuncertain. These costs are recorded in general and administrative expense in the statements of operations.

Stock-based Compensation

The grant date fair value of the endstock-based awards, which have graded vesting, is recognized using the straight-line method over the requisite service period of each reportingstock-based award, which is generally the vesting period using a Monte Carlo simulation (See Note 8).of the respective stock-based awards. The Company recognizes forfeitures as they occur.

Income Taxes

Income Taxes

Deferredtaxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the unaudited condensed consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases.bases and operating loss and tax credit carryforwards. Deferred tax assets including tax loss and credit carry forwards, and liabilities are measured using enacted tax rates expected to applyapplied to taxable income in the years in which those temporary differences are expected to be recovered or settled.realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized inas income or loss in the period that includes the enactment date.

The Company utilizes ASC 740, Income Taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the unaudited condensed consolidated financial statements or tax returns. The Company accounts for income taxes using the asset and liability method to compute the differences between the tax basis of assets and liabilities and the related financial amounts, using currently enacted tax rates. A valuation allowance is recordedestablished when it is “more likely than not” that anecessary to reduce deferred tax asset will notassets to the amount expected to be realized. At September 30, 2021 and December 31, 2020, the Company’s net deferred tax asset has been fully reserved.

For uncertain tax positions that meet a “more likely than not” threshold, the Company recognizes the benefit of uncertain tax positions in the unaudited condensed consolidated financial statements. The Company’s practice is to recognize interestInterest and penalties if any, related to uncertainunrecognized tax positions inbenefits are included within the provision of income tax.

Recent Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. This guidance is effective for fiscal years beginning after December 15, 2021, and interim periods within the fiscal years beginning after December 15, 2022. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s financial statements.

3. Business Combination

As disclosed in Note 1, the Company consummated the Business Combination, pursuant to the terms of the agreement and plan of merger, dated as of August 29, 2021 (the “Business Combination Agreement”), by and among Petra, Petra Acquisition Merger, Inc., a Delaware corporation and wholly-owned subsidiary of Petra (“Merger Sub”), and Old Revelation. Pursuant to the Business Combination Agreement, on the Closing Date, (i) Merger Sub merged with and into Old Revelation (the “Merger”), with Old Revelation as the surviving company in the Merger, and, after giving effect to such Merger, Old Revelation was renamed Revelation Biosciences Sub, Inc. and became a wholly-owned subsidiary of the Company and (ii) the Company changed its name to “Revelation Biosciences, Inc.”

In accordance with the terms and subject to the conditions of the Business Combination Agreement, at the effective time of the Merger (the “Effective Time”), (i) each share of common stock and preferred stock of Old Revelation outstanding as of immediately prior to the Effective Time was exchanged for shares of common stock, par value $0.001 per share, of Revelation based on the agreed upon Common Stock Exchange Ratio; (ii) each Old Revelation RSU award outstanding as of immediately prior to the Effective Time was assumed by Revelation and was converted into that number of whole rollover RSU awards based on the Common Stock Exchange Ratio (“Rollover RSU”); and (iii) each Old Revelation warrant outstanding as of immediately prior to the Effective Time was assumed by Revelation and was converted into that number of whole rollover warrants based on the Common Stock Exchange Ratio, at an exercise price per share of common stock equal to (x) the exercise price per share of Old Revelation common stock of such Old Revelation warrant divided by (y) the Common Stock Exchange Ratio (“Rollover Warrant”).

At the Closing Date, up to 10,500,000 shares of common stock were to be issued constituting the merger consideration, (i) an aggregate of 9,871,343 shares of common stock, including conversion of all outstanding shares of the Series A Preferred Stock and Series A-1 Preferred Stock of Old Revelation, were issued in exchange for the Old Revelation stock outstanding as of immediately prior to the Effective Time, (ii) 167,867 shares of common stock were reserved for issuance for Rollover Warrants outstanding as of

8


immediately prior to the Effective Time and (iii) 460,706 shares of common stock were reserved for issuance for Rollover RSU awards outstanding as of immediately prior to the Effective Time.

Immediately after giving effect to the Business Combination, there were 12,944,213 shares of common stock outstanding, and 1,294,421 shares of common stock reserved for future issuance under the 2021 Equity Incentive Plan. The pre-merger stockholders of Petra retained an aggregate of 3,072,870 shares of common stock of Petra, representing 23.7% ownership of the post-Merger company. Therefore, upon consummation of the Business Combination, there was a change in control of Petra, with the former owners of Revelation Sub acquiring control of Petra.

Prior to the Closing date, on December 21, 2021, Petra entered into certain backstop agreements (the “Backstop Agreements”) with AXA Prime Impact Master Fund (“AXA”) (through a backstop agreement with Old Revelation), LifeSci Venture Partners (“LifeSci”) and other Petra and Old Revelation institutional, and individual investors, including Dr. Tidmarsh, Chairman of Old Revelation and present Chairman of the Company (such additional institutional and individual investors, together with LifeSci and Old Revelation collectively, the “Backstop Subscribers”). Pursuant to the Backstop Agreements, the Backstop Subscribers agreed to purchase, in the aggregate, up to $4.5 million of shares of Petra’s common stock, par value $0.001 per share, in the earningsevent that more than $31.5 million was redeemed from the trust account in connection with the Business Combination. On January 6, 2022, pursuant to the Backstop Agreements, the Backstop Subscribers purchased an aggregate of 432,072 shares of Petra Common Stock that had been surrendered for redemption totaling $4.5 million. Petra also entered into a forward share purchase agreement (the “Forward Share Purchase Agreement”) with Meteora Capital Partners and its affiliates (collectively, “Meteora”) pursuant to which Meteora committed, to purchase additional shares of the Company's common stock in open market transactions or from redeeming stockholders so that Meteora held at least 750,000 shares of common stock as of the closing of the Business Combination. The Forward Share Purchase Agreement provides that Meteora may elect to sell and transfer to the Company, on the one month anniversary of the closing of the Business Combination up to 750,000 shares of common stock held by Meteora at the time of closing of the Business Combination at a price of $10.2031 per share.

Additionally, in connection with the Business Combination, stockholders holding 3,480,692 shares of Petra common stock exercised their right to redeem such shares for cash at a price of approximately $10.20 per share for payments in the aggregate of approximately $35.5 million. On the Closing Date, approximately $7.7 million was escrowed pursuant to the Forward Share Purchase Agreement entered into by and between Petra and Meteora and approximately $4.2 million was released to Revelation. On February 4, 2022, Meteora exercised the Forward Share Purchase Agreement entered into by and between the Company. 750,000 shares were repurchased by the Company and approximately $7.7 million that was escrowed was paid to Meteora.

At the Closing Date of the Business Combination, Petra adopted the third amended and restated certificate of incorporation, which became effective upon filing with the Secretary of State of the State of Delaware on the Closing Date.

Subsequent to the Closing Date on February 10, 2022 and February 22, 2022 the Company paid $105,490 and $691,392, respectively, to the three holders of promissory notes made to Petra in connection with the Business Combination (Promissory Notes Payable). The Promissory Notes Payable had a total principal of $750,000, and had accrued interest of $46,882 at the time of repayment.

The Business Combination has been accounted for as a reverse recapitalization, in accordance with U.S. GAAP. Under this method of accounting, although Petra issued shares for outstanding equity interests of Old Revelation in the Business Combination, Petra was treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination was treated as the equivalent of Old Revelation issuing stock for the net assets of Petra, accompanied by a recapitalization. The net assets of Petra have been stated at historical cost, with 0 goodwill or other intangible assets recorded. Operations prior to the Business Combination are those of Revelation.

In January 2022, in connection with the Business Combination, the Board of Directors adopted the 2021 Equity Incentive Plan (the “2021 Plan”) and reserved 1,294,421 authorized shares of common stock the Company could issue. As of March 31, 2022, there were 939,969 shares available for future grant under the 2021 Plan.

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 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 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.

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.

Restricted Stock Units

At the Closing Date of the Business Combination, all Revelation RSU holders received a Rollover RSU in exchange for each RSU of Revelation Sub at an exchange ratio of 2.725 that vest in accordance with the original terms of the award.

Agreement and Plan of Merger

On August 29, 2021, the Company entered into an Agreement and Plan of Merger (the “Agreement”) with Petra Acquisition Merger Inc., a Delaware corporation (“Merger Sub”), and Revelation Biosciences, Inc., a Delaware corporation (“RevBio”).

In accordance with the terms of the Agreement, at the Closing the Company will issue 10,500,000 shares of its common stock to RevBio as consideration for 100% of RevBio’s outstanding equity interests. Immediately following the Closing, the Company will have 12,319,538 (excluding 7,278,151 shares subject to redemption) shares of common stock issued and outstanding. The pre-merger shareholders of the Company will retain an aggregate of 1,819,538 shares of common stock of the Company, representing 14% ownership of the post-Merger Company. Therefore, upon consummation of the Merger, there will be a change in control of the Company, with the former owners of RevBio effectively acquiring control of the Company.

In connection with measuring the fair value of its assetscashless exercise right and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities basedexpire on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

January 25, 2027.

Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability.

The following table presents information about the Company’s assets that are measured at fair value on a recurring basis at September 30, 2021 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, and risk-free interest rate. The Company estimates the volatility of its common stock warrants based on implied volatility fromBlack-Scholes option pricing model with the Company’s traded warrants and from historical volatility of select peer companies’ common stock that matches the expected remaining life of the Warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the Warrants.

Throughout this section, unless otherwise noted, “we,” “our,” “us,” “Revelation” and the “Company” refer to Revelation Biosciences, Inc. and its subsidiary.

Overview

Revelation is a clinical-stage biopharmaceutical company founded in May 2020. We are focused on the Risk Factors sectiondevelopment or commercialization of immune system therapeutics and diagnostics. Our current product candidates are being developed for the prevention, treatment and detection of allergies and viral infections. REVTx-99a, is being developed as a broad anti-viral nasal drop for the potential prevention or treatment of respiratory viral infections. REVTx-99b is being developed for the prevention or treatment of nasal congestion due to allergies or chronic rhinosinusitis. Our lead diagnostic, REVDx-501 (REVIDTM Rapid Test Kit), is being developed as a rapid point of care diagnostic product that can potentially be used to detect various respiratory viral infections.

Since our inception in May 2020, we have devoted substantially all of our resources to organizing and staffing our Company, business planning, raising capital, and research and development of REVTx-99a/b and REVDx-501, our product candidates.

We have funded our operations since our inception in May 2020 to March 31, 2022 through the issuance and sale of our capital stock, from which we have raised net proceeds of $25.5 million. Our current cash and cash equivalents balance will not be sufficient to complete all necessary product development or future commercialization efforts. We anticipate that our current cash and cash equivalents balance will not be sufficient to sustain operations within one year after the date that our unaudited financial statements for March 31, 2022 were issued, which raises substantial doubt about our ability to continue as a going concern.

We plan to seek additional funding through public or private equity or debt financings. We 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 our stockholders. If we are unable to obtain funding we could be required to delay, reduce or eliminate research and development programs, product portfolio expansion or future commercialization efforts, which could adversely affect our business operations.

We have incurred recurring losses since our inception, including a net loss of $6.6 million and $2.6 million for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022 we had an accumulated deficit of $21.1 million. We expect to continue to generate operating losses and negative operating cash flows for the foreseeable future if and as we:

continue the research and development of our product candidates;
initiate clinical studies for, or preclinical development of, our product candidates;
further develop and refine the manufacturing processes of our product candidates;
change or add manufacturers or suppliers of product candidate materials;
seek regulatory and marketing authorizations for any of our product candidates that successfully complete development;
acquire or license other product candidates, technologies or biological materials;
make milestone, royalty or other payments under future license agreements;
obtain, maintain, protect and enforce our intellectual property portfolio;
seek to attract and retain new and existing skilled personnel;
create additional infrastructure to support our operations as a public company and incur increased legal, accounting, investor relations and other expenses; and
experience delays or encounter issues with any of the Company’s final prospectus for its Initial Public Offering filed with the U.S. Securitiesabove.

18


Our net losses may fluctuate significantly from quarter-to-quarter and Exchange Commission (the “SEC”). The Company’s securities filings can be accessedyear-to-year, depending on the EDGAR sectiontiming of our clinical studies and our expenditures on other research and development activities.

We have never generated revenue and do not expect to generate revenue from product sales unless and until we successfully complete development and obtain regulatory approval for REVTx-99a/b, REVDx-501 or other product candidates, which we expect will not be for at least several years, if ever. Accordingly, until such time as we can generate significant revenue from sales of REVTx-99a/b, REVDx-501 or other product candidates, if ever, we expect to finance our cash needs through a combination of public or private equity offerings, debt financings or other capital sources, including potential collaborations, licenses and other similar arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements when needed would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Recent Developments

Business Combination

On January 10, 2022, we consummated the previously announced Business Combination, pursuant to the terms of the SEC’s website at www.sec.gov. Exceptagreement and plan of merger, dated as expressly requiredof August 29, 2021 with Petra and Merger Sub. Pursuant to the Business Combination Agreement, on the Closing Date, (i) Merger Sub merged with and into Revelation Sub, with Revelation Sub as the surviving company in the Business Combination, and became a wholly-owned subsidiary of Petra and (ii) Petra changed its name to “Revelation Biosciences, Inc.”

Research and Development

Research and development expenses consist primarily of costs incurred for the development of our lead product candidates, REVTx-99a/b and our lead diagnostic product REVDx-501. Our research and development expenses consist primarily of external costs related to clinical development, costs related to contract research organizations, costs related to consultants, costs related to acquiring and manufacturing clinical study materials, costs related to contract manufacturing organizations and other vendors, costs related to the preparation of regulatory submissions, costs related to laboratory supplies and services, and personnel costs. Personnel and related costs consist of salaries, employee benefits and stock-based compensation for personnel involved in research and development efforts.

We expense all research and development expenses in the periods in which they are incurred. We accrue for costs incurred as the services are being provided by applicable securities law,monitoring the Company disclaimsstatus of specific activities and the invoices received from our external service providers. We adjust our accrual as actual costs become known.

We expect our research and development expenses to increase substantially for the foreseeable future as we continue the development of REVTx-99a/b and REVDx-501 and continue to invest in research and development activities. The process of conducting the necessary clinical research and product development to obtain regulatory approval is costly and time consuming, and the successful development of REVTx-99a/b, REVDx-501 and any intentionfuture product candidates is highly uncertain. To the extent that either REVTx-99a/b continue to advance into larger and later stage clinical studies, our expenses will increase substantially and may become more variable.

The actual probability of success for REVTx-99a/b, REVDx-501 or obligationany future product candidate may be affected by a variety of factors, including the safety and efficacy of our product candidates, investment in the development of REVDx-501, investment in our clinical programs, manufacturing capability and competition with other products. As a result, we are unable to updatedetermine the timing of initiation, duration and completion costs of our research and development efforts or revisewhen and to what extent we will generate revenue from the commercialization and sale of REVTx-99a/b, REVDx-501 or any forward-looking statements whetherfuture product candidate.

General and Administrative

Our general and administrative expenses consist primarily of personnel costs, expenses for outside professional services, including financial advisory, legal, human resource, audit and accounting services and consulting costs. Personnel and related costs consist of salaries, employee benefits and stock-based compensation for personnel involved in executive, finance and other administrative functions. We expect our general and administrative expenses to increase for the foreseeable future as we increase the size of our administrative function to support the growth of our business and support our continued research and development activities. We also anticipate increased expenses as a result of new information, future events or otherwise.operating as a public company, including increased expenses related to

Research and development expenses increased by $2.1 million, from $1.6 million for the three months ended March 31, 2021 to $3.7 million for the three months ended March 31, 2022. The increase was primarily due to an increase of $2.2 million in clinical study expenses related to REVTx-99a, $0.2 million in clinical study expenses related to REVTx-99b, $0.1 million in REVTx-99a/b manufacturing expenses and $0.2 million in personnel expenses, which included $57,808 of employee stock-based compensation expense. These increases were offset by a decrease of $0.5 million in diagnostic development expenses related to REVDx-501.

General and administrative expenses increased by $1.9 million, from $1.1 million for the three months ended March 31, 2021 to $2.9 million for the three months ended March 31, 2022. The increase was primarily due to an increase $1.2 million in financial advisory fees, legal fees and professional consulting service fees. In addition, other expenses increased by $0.7 million as a result of an increase in D&O Insurance.

Other Income (Expense), Net

Other income (expense), net was $4,645 for the three months ended March 31, 2021 and $30,241 for the three months ended March 31, 2022, related to interest expense for the Promissory Notes Payable and Convertible Note, foreign currency transaction gains and losses, and interest income from our cash balances in savings accounts.

Liquidity and Capital Resources

Since our inception to March 31, 2022, we have funded our operations from the issuance and sale of our common stock, preferred stock and warrants, from which we have raised net proceeds of $25.5 million, of which $11.6 million was received during the three months ending March 31, 2022. As of March 31, 2022, we had available cash and cash equivalents of $7.2 million and an accumulated deficit of $21.1 million.

Our use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our lead therapeutic product candidates, REVTx-99a/b and the development of our lead diagnostic product, REVDx-501. We plan to increase our research and development expenses substantially for the foreseeable future as we continue the clinical development of our current and future product candidates. At this time, due to the inherently unpredictable nature of product development, we cannot reasonably estimate the costs we will incur and the timelines that will be required to complete development, obtain marketing approval, and commercialize our current product candidate, diagnostic product or any future product candidates. For the same reasons, we are also unable to predict when, if ever, we will generate revenue from product sales or any future license agreements which we may enter into or whether, or when, if ever, we may achieve profitability. Clinical and preclinical development timelines, the probability of success, and development costs can differ materially from expectations. In addition, we cannot forecast the timing and amounts of milestone, royalty and other revenue from licensing activities, which future product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements.

We are a blank check company formed under the laws of the State of Delaware on November 20, 2019expect to continue to generate substantial operating losses for the purposeforeseeable future as we expand our research and development activities. We will continue to fund our operations primarily through utilization of effecting a merger, share exchange, asset acquisition, stock purchase, recapitalizationour current financial resources and through additional raises of capital.

To the extent that we raise additional capital through partnerships or reorganization (each a “Business Combination”)licensing arrangements with third parties, we may have to relinquish valuable rights to our product candidates, future revenue streams or research programs or to grant licenses on terms that may not be favorable to us. If we raise additional capital through public or private equity offerings, the ownership interest of our then-existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more businessesof our clinical studies or entities. We intendpreclinical studies, research and development programs or commercialization efforts or grant rights to completedevelop and market our Business Combination using cash from the proceeds from our Initial Public Offering, the exercise of over-allotment option and the sale of the private warrants, our capital stock, debtproduct candidates or a combination of cash, stock and debt.

Our entire activity since inception relates to our formation, to prepare for our Initial Public Offering, which was consummated on October 13, 2020 and identifying a company for a Business Combination.

The issuance of additional shares in connection with an initial Business Combination:

may significantly reduce the equity interest of our stockholders;

may subordinate the rights of holders of common stock if we issue preferred shares with rights senior to those afforded to our shares of common stock;

will likely cause a change in control if a substantial number of our shares of common stock are issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and most likely will also result in the resignation or removal of our present officers and directors; and

may adversely affect prevailing market prices for our securities.

Similarly,diagnostic product even if we issue debt securities, it could result in:would otherwise prefer to develop and market such product candidates or diagnostic product ourselves.

Going Concern

default and foreclosure on our assets if our operating revenues after a Business Combination are insufficient to pay our debt obligations;

acceleration of our obligations to repay the indebtedness even if we have made all principal and interest payments when due if the debt security contains covenants that required the maintenance of certain financial ratios or reserves and we breach any such covenant without a waiver or renegotiation of that covenant;

our immediate payment of all principal and accrued interest, if any, if the debt security is payable on demand; and

our inability to obtain additional financing, if necessary, if the debt security contains covenants restricting our ability to obtain additional financing while such security is outstanding.

We have incurred recurring losses since our inception, including a net loss of $6.6 million for the three months ended March 31, 2022. As of March 31, 2022 we had an accumulated deficit of $21.1 million, a stockholders’ deficit of $98,511 and available cash and cash equivalents of $7.2 million. We expect to continue to incur significant costs in the pursuit of our initial Business Combination. We cannot assure you that our plans to complete our initial Business Combination will be successful.

Recent Developments

On August 29, 2021, we entered into an Agreementoperating and Plan of Merger (the “Agreement”) with Petra Acquisition Merger Inc., a Delaware corporation (“Merger Sub”), and Revelation Biosciences, Inc., a Delaware corporation (“RevBio”). Pursuant to the terms of the Agreement, Merger Sub shall be merged with and into Revbio becoming a wholly-owned subsidiary of the Company. See Note 6 to Item 1 above for a description of the Merger Agreement and the transactions contemplated thereby.

Results of Operations

Our only activities from November 20, 2019 (inception) through September 30, 2021 were organizational activities, those necessary to consummate the Initial Public Offering, described below, searching for a target company for a business combination, and the proposed acquisition of RevBio. We generate non-operating income in the form of interest income on marketable securities held after the Initial Public Offering. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance),net losses, as well as negative cash flows from operations, for due diligence expenses.the foreseeable future as we continue to complete all necessary product development or future commercialization efforts. We have never generated revenue and do not expect to generate revenue from product sales unless and until we successfully complete development and obtain regulatory approval for REVTx-99a/b, REVDx-501 or other product candidates, which we expect will not be for at least several years, if ever. We do not anticipate that our current cash and cash equivalents balance will be sufficient to sustain operations within one year after the date that our unaudited financial statements for March 31, 2022 were issued, which raises substantial doubt about our ability to continue as a going concern.

21


 

17To continue as a going concern, we will need, among other things, to raise additional capital resources. We plan to seek additional funding through public or private equity or debt financings. We 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 our stockholders. If we are unable to obtain funding we could be required to delay, reduce or eliminate research and development programs, product portfolio expansion or future commercialization efforts, which could adversely affect our business operations.

 

The unaudited condensed consolidated financial statements for March 31, 2022, have been prepared on the basis that we will continue as a going concern, and do 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 us to continue as a going concern.

Off-Balance Sheet Arrangements

As of September 30, 2021,March 31, 2022, we haddid not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.

Quantitative and Qualitative Disclosure about Market Risk

We are exposed to market risks in the ordinary course of our business.

Interest Rate Risk

Our cash and cash equivalents of $0, marketable securities of $19,749, prepaid expenses of $19,334, and $73,514,561 held in our Trust account from our IPO and the purchase of private warrants, consistingconsist primarily of cash andhighly liquid investments in money market funds withand cash on hand and have an original maturity date of 90 days or less. The fair value of our cash and cash equivalents would not be significantly affected by either an increase or decrease in interest rates due mainly to the short-term maturities. Interest income on the balancenature of these instruments.

Foreign Currency Risk

Our expenses are generally denominated in the trust account may be used by us to pay taxes. Through September 30, 2021, we did not withdraw any interest earned on the trust account.

We intend to use substantially all of the funds held in the trust account, to acquire a target business and to pay our expenses relating thereto. To the extent that our capital stock is used in whole or in part as consideration to effect a business combination, the remaining funds held in the trust account will be used as working capital to finance the operations of the target business. Such working capital funds could be used in a variety of ways including continuing or expanding the target business’ operations, for strategic acquisitions and for marketing, research and development of existing or new products. Such funds could also be used to repay any operating expenses or finders’ fees which we had incurred prior to the completion of our business combination if the funds available to us outside of the trust account were insufficient to cover such expenses.

18

In order to fund working capital deficiencies or finance transaction costs in connection with a business combination, the Sponsor or our officers and directors or their affiliates may, but are not obligated to, loan us funds on a non-interest basis as may be required. If we complete our initial business combination, we would repay such loaned amounts. In the event that our initial business combination does not close, we may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from our trust account would be used for such repayment. Up to $1,500,000 of notes may be convertible into Private Warrants, at a price of $1.00 per warrant. The warrants would be identical to the Private Warrants.

We do not believe we will need to raise additional funds subsequent to the Initial Public Offering in order to meet the expenditures required for operating our business prior to our initial business combination. However, if our estimates of the costs of identifying a target business, undertaking in-depth due diligence and negotiating an initial business combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our business combination. Moreover, we may need to obtain additional financing either to complete our business combination or because we become obligated to redeem a significant number of our public shares upon completion of our business combination,currencies in which case we may issue additional securities or incur debt in connection with such business combination. If weour operations are unable to complete our initial business combination because we do not have sufficient funds available to us, we will be forced to cease operations and liquidate the trust account.

Off-balance sheet financing arrangements

We have no obligations, assets or liabilities,located, which would be considered off-balance sheet arrangements as of September 30, 2021. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

Contractual obligations

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than the underwriters are entitled to deferred compensation of $0.40 per unit, or $2,800,000 upon completion of a business combination or $3,220,000 in the aggregate if the underwriters’ over-allotment option is exercised in full in the aggregate. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that we complete a Business Combination, subject to the terms of the underwriting agreement.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with accounting principles generally acceptedprimarily in the United States and Australia. We make payments to vendors for research and development services with payments denominated in foreign currencies including Australian Dollars and British Pounds. We are subject to foreign currency transaction gains or losses on our payments denominated in foreign currencies. To date, foreign currency transaction gains and losses have not been material and we have not had a formal hedging program with respect to foreign currency; however, we may consider doing so in the future. A 10% increase or decrease in currency exchange rates would not have a material effect on our financial results.

Critical Accounting Policies and Significant Judgements and Estimates

Our management’s discussion and analysis of Americaour financial condition and results of operations is based on our financial statements, which have been prepared in accordance with the U.S. generally accepted accounting principles (“GAAP”). The preparation of the condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities disclosure ofreported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. These estimates and assumptions are based on management’s best estimates and judgment. Management regularly evaluates its estimates and assumptions using industry experience and other factors; however, actual results could differ materially from these estimates and could have an adverse effect on our condensed consolidated financial statements. While our significant accounting policies are more fully described in the notes to our condensed consolidated financial statements, we believe that the accounting policies discussed below are most critical to understanding and evaluating our historical and future performance.

Research and Development Expenditures

We record accrued expenses for estimated preclinical and clinical study and research expenses related to the services performed but not yet invoiced pursuant to contracts with research institutions, contract research organizations and clinical manufacturing organizations that conduct and manage preclinical studies, and clinical studies, and research services on our behalf.

23


Payments for these services are based on the terms of individual agreements and payment timing may differ significantly from the period in which the services were performed. Our estimates are based on factors such as the work completed, including the level of patient enrollment. We monitor patient enrollment levels and related activity to the extent reasonably possible and make judgments and estimates in determining the accrued balance in each reporting period. Our estimates of accrued expenses are based on the facts and circumstances known at the time. If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates. As actual costs become known, we adjust our accrued expenses. To date, we have not experienced significant changes in our estimates of clinical study accruals.

Stock-based Compensation

We recognize the compensation expense related to stock options, third-party warrants, and RSU awards granted, based on the estimated fair value of the awards on the date of the financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following critical accounting policies as of September 30, 2021.

Common stock subject to possible redemption

We account for common stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable common stock (including common stock that feature redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. Our common stock features certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of our condensed balance sheet.

19

Derivative Warrant Liabilities

The Company accounts for the Warrants in accordance with the guidance contained in ASC 815 under which the Private Warrants do not meet the criteria for equity treatment and must be recorded as derivative liabilities. Accordingly, the Company classifies the Private Warrants as liabilities at their fair value and adjusts the Private Warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until the Private Warrants are exercised or expire, and any change in fair value is recognized in the Company’s statement of operations.grant. The fair value of employee stock options and third-party warrants are generally determined using the Private Warrants was initiallyBlack-Scholes option-pricing model using various inputs, including estimates of expected volatility, term, risk-free rate, and subsequently measured atfuture dividends. The grant date fair value of the endstock-based awards, which have graded vesting, is recognized using the straight-line method over the requisite service period of each reportingstock-based award, which is generally the vesting period usingof the respective stock-based awards. The Company recognizes forfeitures as they occur.

As of March 31, 2022, there were 460,706 Rollover RSU awards and 354,452 stock options outstanding.

Determination of the Fair Value of Common Stock

Prior to the Business Combination, given the absence of a Monte Carlo simulation.public trading market for our shares of common stock, our board of directors exercises its judgment and considers a number of objective and subjective factors to determine the best estimate of the fair value of our shares of common stock, including timely valuations of our shares of common stock prepared by an unrelated third-party valuation firm, important developments in our operations, sales of common stock and convertible preferred shares, actual operating results and financial performance, the conditions in the biotechnology industry and the economy in general, the stock price performance and volatility of comparable public companies, and the lack of liquidity of our shares of common stock, among other factors. After the Business Combination, the fair value of each share of common stock is based on the closing price of our shares of common stock as reported on the date of grant.

ITEMItem 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKQuantitative and Qualitative Disclosures About Market Risk

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this item.

As of September 30, 2021, we were not subject to any market or interest rate risk. Following the consummation of our Initial Public Offering, the net proceeds received into the Trust Account, have been invested in U.S. government treasury bills, notes or bonds with a maturity of 185 days or less or in certain money market funds that invest solely in US treasuries. Due to the short-term nature of these investments, we believe there will be no associated material exposure to interest rate risk.

ITEMItem 4. CONTROLS AND PROCEDURESControls and Procedures

 

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures. Based on that evaluation of our disclosure controls and procedures as of March 31, 2022, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures as of such date are effective at the reasonable assurance level. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in ourthe reports filedthat it files or submittedsubmits under the Exchange Act isare recorded, processed, summarized and reported within the time periods specified in the SEC’sU.S. Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in ourthe reports filedwe file or submittedsubmit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officerprincipal executive officer and Chief Financial Officer,principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Evaluation of Disclosure Controls and Procedures

As required by Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out an evaluation of the effectiveness of the design and operation of our disclosure Management recognizes that any controls and procedures, asno matter how well designed and operated, can provide only reasonable assurance of September 30, 2021. Based on this evaluation, our principal executive officer and principal financial and accounting officer have concluded that, solely due to the events that led to the Company’s restatement of its financial statements to reclassify the Company’s derivative instruments as liabilities (which are described in the Company’s Amendment No. 1 to its Annual Report on Form 10-K/A filed on June 16, 2021) (the “Restatement”), during the period covered by this report, a material weakness existedachieving their objectives, and our disclosuremanagement necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures were not effective.procedures.

Changes in Internal Control Overover Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fiscalour most recent quarter of 2021 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. In light of the material weakness identified and the resulting Restatement, we plan to enhance our processes to identify and appropriately apply applicable accounting requirements to better evaluate and understand the nuances of the complex accounting standards that apply to our financial statements. Our plans at this time include providing enhanced access to accounting literature, research materials and documents and increased communication among our personnel and third-party professionals with whom we consult regarding complex accounting applications. The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.

On October 13, 2020, we consummated the Initial Public Offering of 7,000,000 units. On October 16, 2020, we consummated the sale of an additional 278,151 units subject to the underwriters’ over-allotment option. The units sold in the Initial Public Offering, including pursuant to the over-allotment option, were sold at an offering price of $10.00 per unit, generating total gross proceeds of $72,781,510. LifeSci Capital LLC and Ladenburg Thalmann & Co. Inc., acted as joint book-running managers and Northland Securities, Inc., and Ingalls & Snyder LLC acted as co-managers of the Initial Public Offering. The securities in the offering were registered under the Securities Act on registration statements on Forms S-1 (Nos. 333-240175). The Securities and Exchange Commission declared the registration statement effective on October 7, 2020.

Simultaneous with the consummation of the Initial Public Offering, we consummated the private placement of an aggregate of 3,150,000 private warrants (“Private Warrants”) to our Sponsor at a price of $1.00 per Private Warrant, generating total proceeds of $3,150,000. Simultaneous with the consummation of the underwriters’ over-allotment option, we consummated the private placement of an additional 83,446 Private Warrants to the Sponsor at a price of $1.00 per Private Warrant, generating total proceeds of $83,446.

The Private Warrants are identical to the warrants sold in the Initial Public Offering, except that the private warrants: (i) will not be redeemable by us and (ii) may be exercised for cash or on a cashless basis, as described in this prospectus, in each case so long as they are held by the initial purchasers or any of their permitted transferees. If the private warrants are held by holders other than the initial purchasers or any of their permitted transferees, the private warrants will be redeemable by us and exercisable by the holders on the same basis as the warrants included in the units being sold in this offering. Furthermore, our initial stockholders have agreed to vote the their founders shares in favor of any proposed business combination, as applicable (B) not to convert any founders shares in connection with a stockholder vote to approve a proposed initial business combination or sell any shares to us in a tender offer in connection with a proposed initial business combination and (C) that the founders shares shall not participate in any liquidating distribution from our trust account upon winding up if a business combination is not consummated.
