REVELATION BIOSCIENCES, INC.
Notes to the Consolidated Financial Statements
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. (“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 August 29, 2021 Petra and Old Revelation signed an agreement and plan of merger (the “Business Combination Agreement”). 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 Company’s common stock and warrants are listed on the Nasdaq Capital Market under the symbols “REVB” and “REVBW”, respectively.
Reverse Stock Split
On January 25, 2024, the Company effected the approved 1-for-30 reverse stock split of our shares of common stock. Unless specifically provided otherwise herein, the share and per share information that follows in this Quarterly Report, reflects the effect of the reverse stock split.
Liquidity and Capital Resources
Going Concern
The Company has incurred recurring losses since its inception, including a net loss of $2.7 million for the three months ended March 31, 2024. As of March 31, 2024, the Company had an accumulated deficit of $28.1 million, a stockholders’ equity of $9.5 million and available cash and cash equivalents of $14.6 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 GEM-AKI, GEM-CKD, GEM-SSI or other product candidates, which the Company 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 sustain operations within one-year after the date that the Company’s unaudited financial statements for March 31, 2024 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 unaudited consolidated financial statements for March 31, 2024, 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.
Basis of Presentation
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.
2. Summary of Significant Accounting Policies
Unaudited Interim Condensed Consolidated Financial Statements
The unaudited interim consolidated financial statements have been prepared on the same basis as the audited financial statements as of December 31, 2023 and for the year ended December 31, 2023 and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s financial position. The financial data and the other financial information contained in these notes to the consolidated financial statements related to the three months ended March 31, 2024 are unaudited. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any other future annual or interim period. The consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended December 31, 2023 included on Form 10-K, as filed with the SEC on March 22, 2024. The accompanying consolidated balance sheet as of December 31, 2023 has been derived from the audited balance sheet at December 31, 2023 contained in the above referenced Form 10-K.
Use of Estimates
The preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of expenses. These estimates and assumptions are based on the Company’s best estimates and judgment. The Company regularly evaluates its estimates and assumptions using historical and industry experience and other factors; however, actual results could differ materially from these estimates and could have an adverse effect on the Company’s consolidated financial statements.
Cash and Cash Equivalents
The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. The Company maintains its cash in checking and savings accounts. Income generated from cash held in savings accounts is recorded as interest income. The carrying value of the Company’s savings accounts is included in cash and approximates the fair value.
Concentrations of Credit Risk
Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents. Bank deposits are held by accredited financial institutions and these deposits may at times be in excess of federally insured limits. The Company limits its credit risk associated with cash and cash equivalents by placing them with financial institutions that it believes are of high quality. The Company has not experienced any losses on its deposits of cash or cash equivalents.
Deferred Offering Costs
The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings as deferred offering costs until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds generated as a result of the offering. Should the planned equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the consolidated statements of operations.
Property and Equipment, Net
Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which is five years. Maintenance and repairs are charged to operating expense as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any gain or loss is included in other (expense) income.
Leases
The Company determines if an arrangement is a lease at inception. Lease right-of-use assets represent the right to use an underlying asset for the lease 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 similar 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 product candidates, GEM-AKI, GEM-CKD, GEM-SSI and other product candidates. 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 Company’s behalf. 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. Estimates are based on factors such as the work completed, including the level of patient enrollment. The Company monitors patient enrollment levels and related activity to the extent reasonably possible and makes judgments and estimates in determining the accrued balance in each reporting period. The 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 uncertain. These costs are recorded in general and administrative expenses in the consolidated statements of operations.
Stock-based Compensation
The Company recognizes stock-based compensation expense related to stock options, third-party warrants, and Restricted Stock Unit (“RSU”) awards granted, based on the estimated fair value of the stock-based awards on the date of grant. The fair value of employee stock options and third-party warrants are generally determined using the Black-Scholes option-pricing model using various inputs, including estimates of historic volatility, term, risk-free rate, and future dividends. The grant date fair value of the stock-based awards, which have graded vesting, is recognized using the straight-line method over the requisite service period of each stock-based award, which is generally the vesting period of the respective stock-based awards. The Company recognizes forfeitures as they occur.
Income Taxes
Income taxes 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 financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates applied to taxable income in the years in which those temporary differences are expected to be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or loss in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized. Interest and penalties related to unrecognized tax benefits are included within the provision of income tax. To date, there have been no unrecognized tax benefits balances.
Fair Value
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company’s valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company follows a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. These levels of inputs are the following:
Level 1—Quoted prices in active markets for identical assets or liabilities.
Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The Company has determined that the measurement of the fair value of the Class C Common Stock Warrants (as defined in Note 5) is a Level 3 fair value measurement and uses the Monte-Carlo simulation model for valuation (see Note 10).
Warrant Liability
The Company reviews the terms of debt instruments, equity instruments, and other financing arrangements to determine whether there are embedded derivative features, including embedded conversion options that are required to be bifurcated and accounted for separately as a derivative financial instrument. Additionally, in connection with the issuance of financing instruments, the Company may issue freestanding options and warrants.
The Company accounts for its common stock warrants in accordance with ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). Based upon the provisions of ASC 480 and ASC 815, the Company accounts for common stock warrants as current liabilities if the warrant fails the equity classification criteria. Common stock warrants classified as liabilities are initially recorded at fair value on the grant date and remeasured at each balance sheet date with the offsetting adjustments recorded in change in fair value of warrant liabilities within the consolidated statements of operations.
The Company values its Class C Common Stock Warrants classified as liabilities using the Monte-Carlo simulation model.
Basic and Diluted Net (Loss) Earnings per Share
Basic net (loss) earnings per share is calculated by dividing net (loss) income by the weighted-average number of shares of common stock outstanding during the period, without consideration of potential shares of common stock. Diluted net (loss) earnings per share is calculated by dividing net (loss) income by the weighted-average number of shares of common stock outstanding plus potential shares of common stock. Convertible preferred stock on an as converted basis, RSU awards, warrants and stock options outstanding are considered potential shares of common stock and are included in the calculation of diluted net (loss) earnings per share using the treasury stock method when their effect is dilutive. Potential shares of common stock are excluded from the calculation of diluted net (loss) earnings per share when their effect is anti-dilutive.
As of March 31, 2024, there were 30,466 potential shares of common stock, respectively, (see Note 8), that were excluded from the calculation of diluted net loss per share because their effect was anti-dilutive.
For the three months ended March 31, 2023, there were 30,839 million potential common shares that were included in the calculation of diluted net earnings per share, which consists of: (i) 28,099 shares of common stock issuable upon the alternative cashless exercise of the Class C Common Stock Warrants; (ii) 2,496 Class C Pre-Funded Warrants; and (iii) 244 Rollover RSU awards.
For the three months ended March 31, 2023, the basic and diluted weighted-average shares used to compute net earnings per share in the unaudited consolidated statements of operations includes the shares issued from the reverse stock split fractional share round up.
Comprehensive (Loss) Income
The Company has no components of comprehensive (loss) income other than net (loss) income. Thus, comprehensive (loss) income is the same as net (loss) income for the periods presented.
Segment Reporting
Operating segments are defined as components of an entity about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources in assessing performance.
The Company has one operating segment. The Company’s chief operating decision maker manages the Company’s operations for the purposes of allocating resources and evaluating financial performance.

4. Commitments and Contingencies
Lease Commitments
The Company leases 2,140 square feet of laboratory space located at 11011 Torreyana Road, Suite 102, San Diego, California (the “Lease”). In January 2024, the Company signed an amendment extending the Lease until November 30, 2024, with a base monthly rent equal to $5,350. The Company is required to maintain a security deposit of $5,564. The Lease contains customary default provisions, representations, warranties and covenants. In addition to rent, the Lease requires the Company to pay certain taxes, insurance and operating costs relating to the leased premises. The Company has applied the short-term lease exception as the amendment is less than twelve months. The Lease is classified as an operating lease.
Rent expense was $16,050 for the three months ended March 31, 2024 and $24,991 for the three months ended March 31, 2023, respectively.
Future minimum lease payments under the operating lease as of March 31, 2024 is $42,800.
Commitments
The Company enters into contracts in the normal course of business with third party service providers and vendors. These contracts generally provide for termination on notice and, therefore, are cancellable contracts and not considered contractual obligations and commitments.
Contingencies
From time to time, the Company may become subject to claims and litigation arising in the ordinary course of business. The Company is not a party to any material legal proceedings, nor is it aware of any material pending or threatened litigation other than described below.
Legal Proceedings
On February 18, 2022, LifeSci Capital LLC filed an action against the Company in the U.S. District Court for the Southern District of New York seeking damages in the amount of approximately $5.3 million plus interest for unpaid banking and advisory fees. These fees arise under contracts which were entered into prior to the Business Combination and the Company has asserted that LifeSci Capital LLC is not entitled to the fee because it violated its responsibilities by misrepresenting to Petra the funds that would be available following the Business Combination, absent which Petra would not have entered into the Business Combination Agreement. This action remains pending as of the date of this report. $1.5 million of the claim relates to deferred underwriting commissions from the Petra initial public offering, which are recorded as a current liability in the financial statements as of March 31, 2024 under deferred underwriting commissions. On December 1, 2023 a Magistrate Judge issued a report recommending summary judgment in favor of LifeSci Capital LLC. On December 15, 2023, the Company filed objections to the Magistrate’s report asserting that the Magistrate Judge made factual determinations not appropriate for summary judgment and misapplied the law. The Magistrate’s report is a recommendation to the trial judge who is responsible for reviewing the case de novo. Other than the deferred underwriting commissions, no liabilities are reflected in the financial statements as the amount of any additional liability cannot be determined at this time.

9. Stock-Based Compensation
2021 Equity Incentive Plan
In January 2022, in connection with the Business Combination, the Board of Directors and the Company’s stockholders adopted the 2021 Equity Incentive Plan (the “2021 Plan”) and reserved 1,232 authorized shares of common stock for issuance under the plan. 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, and began on January 1, 2022, by 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 July 14, 2023 at the Company’s 2023 Annual Meeting of Stockholders, an amendment to the 2021 Equity Incentive Plan to increase the number of shares reserved under the Plan to 21,623 was approved.
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.
As of March 31, 2024, there were 20,466 shares available for future grants under the 2021 Plan.
Restricted Stock Units
At 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 25% on the one-year anniversary and the remainder vesting monthly thereafter for grants to officers, employees and consultants. The milestone-based vesting conditions vested on the Closing Date of the Business Combination.
As of March 31, 2024 and December 31, 2023, the Company has a total of 94 Rollover RSU awards for shares of common stock outstanding, respectively. As of March 31, 2024, 61 Rollover RSU awards have fully vested but are unissued and no Rollover RSU awards have been forfeited. As of March 31, 2024, 94 Rollover RSU awards will vest and be issued over the next 0.9 years. Each Rollover RSU award converts to one share of common stock.
Stock Options
The Company has granted stock options which (i) vest fully on the date of grant; (ii) vest 25% on the one-year anniversary of the grant date or the employees hiring date, with the remainder vesting quarterly thereafter; or (iii) vest quarterly over one-year, for grants to Board of Directors, officers and employees. Stock options have a maximum term of 3 or 10 years.

For the three months ended March 31, 2024, the weighted-average Black-Scholes value per stock option was $314.03. The fair value of the stock options was estimated using the Black-Scholes option pricing model with the following weighted-average assumptions:

|

Expected volatility is based on the historical volatility of shares of the Company’s common stock. 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
For the three months ended March 31, 2024 and 2023, the Company recorded stock-based compensation expense for the period indicated as follows:

Class B Placement Agent Common Stock Warrants
In connection with the July 2022 Public Offering, the Company issued warrants to the Placement Agent to purchase up to 556 shares of common stock at an exercise price of $787.50 per share (the “Class B Placement Agent Common Stock Warrants”), valued on the public offering purchase date in the aggregate at $0.3 million and included in the issuance costs of the public offering and treated as equity. The warrants were exercisable immediately upon issuance, provide for a cash or cashless exercise right and expire on July 25, 2027.
The fair value of the Class B Placement Agent Common Stock Warrants were estimated using the Black-Scholes option pricing model with the following assumptions:

Class C Pre-Funded Warrants
In connection with the February 2023 Public Offering, the Company issued pre-funded warrants to purchase up to 11,214 shares of common stock at an exercise price of $0.003 per share. Between February 14, 2023 and April 6, 2023, the Company received notices of cash exercise for the Class C Pre-Funded Warrants issued in connection with the February 2023 Public Offering for 336,400 shares of common stock at a total purchase price of $33.64. As of March 31, 2024, there were no Class C Pre-Funded Warrants outstanding.
Class C Common Stock Warrants
In connection with the February 2023 Public Offering, the Company issued 6,450,000 warrants to purchase up to 215,000 shares of common stock at an exercise price of $160.80 per share, valued on the public offering purchase date in the aggregate at $13,996,500 and included in the issuance costs of the public offering and treated as a liability . The warrants were exercisable immediately upon issuance, provide for a cash, cashless exercise right or an alternative cashless exercise right for 0.4 shares of common stock per Class C Common Stock Warrant and expire on February 14, 2028.
The Company evaluated the Class C Common Stock Warrants under ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity (“ASC 815-40”) and concluded that they do not meet the criteria to be classified in stockholders’ equity and accounted for the Class C Common Stock Warrants as current liabilities.
The Company concluded that the multiplier of 0.4 shares of common stock per Class C Common Stock Warrant used in the alternative cashless exercise precludes the Class C Common Stock Warrants from being considered indexed to the Company’s stock. The Company recorded the Class C Common Stock Warrants as current liabilities on the balance sheet at fair value, with subsequent changes in their respective fair values recognized in the consolidated statements of operations at each reporting date. Estimating fair values of liability-classified financial instruments requires the development of estimates that may, and are likely to, change over the duration of the instrument with related changes in internal and external market factors. In addition, option-based techniques are highly volatile and sensitive to changes in the trading market price of the Company’s common stock. Because liability-classified financial instruments are initially and subsequently carried at fair value, the Company’s financial results will reflect the volatility in these estimate and assumption changes. Changes in fair value are recognized as a component of other (expense) income in the consolidated statements of operations.
At the date of issuance, the Company valued the Class C Common Stock Warrants using a Monte-Carlo simulation model with a fair value of $14.0 million.
As of March 31, 2024, the Company received notices of alternative cashless exercises for 6,217,640 Class C Common Stock Warrants issued in connection with the February 2023 Public Offering for 82,919 shares of common stock.
As of March 31, 2024, the Company re-valued 232,360 outstanding Class C Common Stock Warrants to purchase up to 7,746 shares of common stock using a Monte-Carlo simulation model with a fair value of $15,260.0 million. For the three months ended March 31, 2024, the gain of $0.1 million, respectively, resulting from the change in the fair value of the liability for the unexercised warrants was recorded as a change in fair value of the warrant liability in the accompanying consolidated statements of operations for the three months ended March 31, 2024.
As part of the February 2024 Public Offering, the exercise price of the Class C Common Stock Warrants issued in the February 2023 Public Offering was reset from $160.80 to $4.53.
Class D Pre-Funded Warrants
In connection with the February 2024 Public Offering, the Company issued pre-funded warrants to purchase up to 1,236,530 shares of common stock at an exercise price of $0.0001 per share. Between February 5, 2024 and February 13, 2024, the Company received notices of cash exercise for the Class D Pre-Funded Warrants issued in connection with the February 2024 Public Offering for 1,236,530 shares of common stock at a total purchase price of $123.65. As of March 31, 2024, there were no Class D Pre-Funded Warrants outstanding.
Class D Common Stock Warrants
In connection with the February 2024 Public Offering, the Company issued and has outstanding 2,730,000 warrants shares of common stock at an exercise price of $4.53 per share, valued on the public offering purchase date in the aggregate at $6.3 million and included in the issuance costs of the public offering and treated as equity. The warrants were exercisable immediately upon issuance, provide for a cash or cashless exercise right and expire on February 5, 2029.

11. Income Taxes
The quarterly provision for or benefit from income taxes is computed based upon the estimated annual effective tax rate and the year-to-date pre-tax (loss) income and other comprehensive (loss) income. The Company did not record a provision or benefit for income taxes during the three months ended March 31, 2024 and 2023, respectively.
For the three months ended March 31, 2024 and 2023, the Company recorded non-taxable income of $0.1 million and $7.7 million, respectively, related to a change in the fair value of a warrant liability. The Company incurred taxable losses in 2023 and projects further taxable losses for 2024. The Company did not record a benefit from income taxes because, based on evidence involving its ability to realize its deferred tax assets, the Company recorded a full valuation allowance against its deferred tax assets.
14. Subsequent Events
On April 26, 2024 the Company entered into a confidential settlement agreement with A-IR Clinical Research Ltd. (“A-IR”) for a previously filed claim against the Company in the High Court of Justice, in the Business and Property Courts of England and Wales and is included in other (expense) income in the accompanying consolidated statements of operations.
Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
You should read the following discussion of our financial condition and results of operations in conjunction with our unaudited financial statements and the notes included elsewhere in this Form 10-Q. The following discussion contains forward-looking statements that involve certain risks and uncertainties. Our actual results could differ materially from those discussed in these statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this form 10-Q or our Annual Report Form 10-K for the year ended December 31, 2023, particularly under the “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements and Risk Factors Summary” sections.
Overview
Revelation is a clinical-stage biopharmaceutical company founded in May 2020. We are focused on harnessing the power of trained immunity for the prevention and treatment of disease by developing and commercializing therapeutics that modulate the innate immune system. Our current product candidates were developed by us and licensed to potentially prevent, treat and detect disease. Our therapeutic product candidates are based on our therapeutic platform and consist of GEM-AKI, which is being developed as a potential therapy for the prevention and treatment of acute kidney injury as a result of cardiac surgery; GEM-CKD, which is being developed as a potential therapy for the prevention and treatment of chronic kidney disease; and GEM-SSI, which is being developed for the prevention and treatment of surgical sit infection.
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 GEM-AKI, GEM-CKD and GEM-SSI, our product candidates.
We have funded our operations since our inception in May 2020 to March 31, 2024 through the issuance and sale of our capital stock, from which we have raised net proceeds of $49.3 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, 2024 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 $2.7 million for the three months ended March 31, 2024 and $6.2 million for the three months ended March 31, 2023, respectively. As of March 31, 2024 we had an accumulated deficit of $28.1 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 above.
Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing 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 GEM-AKI, GEM-CKD, GEM-SSI 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 GEM-AKI, GEM-CKD, GEM-SSI 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
2024 Reverse Stock Split
On January 25, 2024, the Company effected a 1-for-30 reverse stock split of our outstanding shares of common stock, which had been approved at a special meeting of stockholders.
Research and Development
Research and development expenses consist primarily of costs incurred for the development of our product candidates GEM-AKI, GEM-CKD and GEM-SSI. 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 monitoring the status 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 GEM-AKI, GEM-CKD and GEM-SSI 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 GEM-AKI, GEM-CKD and GEM-SSI and any future product candidates is highly uncertain. To the extent that our product candidates 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 GEM-AKI, GEM-CKD and GEM-SSI or any future product candidate may be affected by a variety of factors, including the safety and efficacy of our product candidates, investment in our clinical programs, manufacturing capability and competition with other products. As a result, we are unable to determine the timing of initiation, duration and completion costs of our research and development efforts or when and to what extent we will generate revenue from the commercialization and sale of GEM-AKI, GEM-CKD and GEM-SSI or any future 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 we continue to operate as a public company, including increased expenses related to financial advisory services, audit, legal, regulatory, investor relations costs, director and officer insurance premiums associated with maintaining compliance with exchange listing and SEC requirements.
Other (Expense) Income, Net
Other (expense) income, net primarily consists of the change in fair value of warrant liability, clinical trial related expenses, foreign currency transaction gains and losses, interest expense and interest income from our cash balances in savings accounts.

Research and development expenses increased by $0.2 million, from $0.5 million for the three months ended March 31, 2023 to $0.7 million for the three months ended March 31, 2024. The increase was primarily due to increases of $0.3 million in clinical study expenses related to GEM-AKI and GEM-SSI and $0.2 million in personnel expenses, offset by a decrease of $0.3 million in manufacturing expenses.

General and administrative expenses increased by $0.1 million, from $1.1 million for the three months ended March 31, 2023 to $1.2 million for the three months ended March 31, 2024. The increase was primarily due to increases of $0.3 million in personnel expenses, offset by a decrease of $0.2 million in legal and professional fees.
Other (Expense) Income, Net
Other (expense) income, net was $7,779,042 for the three months ended March 31, 2023, related to the change in fair value of the warrant liability, foreign currency transaction gains and losses, and interest income from our cash balances in savings accounts. Other (expense) income, net was $779,295 for the three months ended March 31, 2024, related to the change in fair value of the warrant liability, clinical trial related settlement expenses with A-IR, 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, 2024, 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 $49.3 million, of which $5.4 million was received during the three months ended March 31, 2024. As of March 31, 2024, we had available cash and cash equivalents of $14.6 million and an accumulated deficit of $28.1 million.
Our use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our therapeutic product candidates, GEM-AKI, GEM-CKD and GEM-SSI. 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 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 expect to continue to generate substantial operating losses for the foreseeable future as we expand our research and development activities. We will continue to fund our operations primarily through utilization of our current financial resources and through additional raises of capital.
To the extent that we raise additional capital through partnerships or 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 of our clinical studies or preclinical studies, research and development programs or commercialization efforts or grant rights to develop and market our product candidates even if we would otherwise prefer to develop and market such product candidates ourselves.
Going Concern
We have incurred recurring losses since our inception, including a net loss of $2.7 million for the three months ended March 31, 2024. As of March 31, 2024 we had an accumulated deficit of $28.1 million, a stockholders’ equity of $9.5 million and available cash and cash equivalents of $14.6 million. We expect to continue to incur significant operating and net losses, as well as negative cash flows from operations, for 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 GEM-AKI, GEM-CKD, GEM-SSI 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, 2024 were issued, which raises substantial doubt about our ability to continue as a going concern.
To 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 consolidated financial statements for March 31, 2024, 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.

We have entered into an operating lease for laboratory space in San Diego, California. The table above includes future minimum lease payments under the non-cancelable lease arrangement.
We enter into contracts in the normal course of business with third party service providers and vendors. These contracts generally provide for termination on notice and, therefore, are cancellable contracts and not considered contractual obligations and commitments. We believe that our non-cancelable obligations under these agreements are not material.
Off-Balance Sheet Arrangements
As of March 31, 2024, we did 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 consist primarily of highly liquid investments in money market funds and 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 nature of these instruments.
Foreign Currency Risk
Our expenses are generally denominated in the currencies in which our operations are located, which is primarily in the United States, England 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 our 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 consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, 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 consolidated financial statements. While our significant accounting policies are more fully described in the notes to our 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. 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 grant. The fair value of employee stock options and third-party warrants are generally determined using the Black-Scholes option-pricing model using various inputs, including estimates of historic volatility, term, risk-free rate, and future dividends. The grant date fair value of the stock-based awards, which have graded vesting, is recognized using the straight-line method over the requisite service period of each stock-based award, which is generally the vesting period of the respective stock-based awards. The Company recognizes forfeitures as they occur.
As of March 31, 2024, there were 94 Rollover RSU awards unvested and unissued and 1,157 stock options outstanding.
Determination of the Fair Value of Common Stock
Prior to the Business Combination, given the absence of a public trading market for our shares of common stock, our board of directors exercised its judgment and considered 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.
Recent Accounting Pronouncements
See Note 2 to our unaudited consolidated financial statements for more information about recent accounting pronouncements, the timing of their adoption, and our assessment, to the extent we have made one yet, of their potential impact on our financial condition of results of operations.
JOBS Act Accounting Election
We are an “emerging growth company,” as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies.
We have elected to use this extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements and our interim condensed financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.
Item 3. Quantitative 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.
Item 4. Controls 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, 2024, 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 the reports that it files or submits under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the U.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 the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting that occurred during our most recent quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
PART II—OTHER INFORMATION
Item 1. Legal Proceedings.
On February 18, 2022, LifeSci Capital LLC filed an action against the Company in the U.S. District Court for the Southern District of New York seeking damages in the amount of approximately $5.3 million plus interest for unpaid banking and advisory fees. These fees arise under contracts which were entered into prior to the Business Combination and the Company has asserted that LifeSci Capital LLC is not entitled to the fee because it violated its responsibilities by misrepresenting to Petra the funds that would be available following the Business Combination, absent which Petra would not have entered into the Business Combination Agreement. This action remains pending as of the date of this report. $1.5 million of the claim relates to deferred underwriting commissions from the Petra initial public offering, which are recorded as a current liability in the financial statements as of September 30, 2022 under deferred underwriting commissions. On December 1, 2023 a Magistrate Judge issued a report recommending summary judgment in favor of LifeSci Capital LLC. On December 15, 2023, the Company filed objections to the Magistrate’s report asserting that the Magistrate Judge made factual determinations not appropriate for summary judgment and misapplied the law. The Magistrate’s report is a recommendation to the trial judge who is responsible for reviewing the case de novo. Other than the deferred underwriting commissions, no liabilities are reflected in the financial statements as the amount of any additional liability cannot be determined at this time.
On September 27, 2022, A-IR Clinical Research Ltd. (“A-IR”) filed a claim against the Company in the High Court of Justice, in the Business and Property Courts of England and Wales, seeking £1.6 million in unpaid invoices, plus interest and costs, relating to the Company’s viral challenge study. The Company had disputed the claim because many of the invoices relate to work that was not performed and A-IR had misrepresented its qualifications to perform the contracted work. On April 26, 2024 the parties settled the claim and the proceedings were withdrawn with prejudice.
Item 1A. Risk Factors.
Our business is subject to various risks, including those described in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023. There have been no material changes from the risk factors disclosed in Item 1A of our Annual Report on Form 10-K.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.
Item 3. Defaults Upon Senior Securities.
Not applicable.
Item 4. Mine Safety Disclosures.
Not applicable.
Item 5. Other Information.
None.
Item 6. Exhibits, Financial Statement Schedules.
Furnish the exhibits required by Item 601 of Regulation S-K (§ 229.601 of this chapter).

Organization and Basis of Presentation |
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. (“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 August 29, 2021 Petra and Old Revelation signed an agreement and plan of merger (the “Business Combination Agreement”). 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 Company’s common stock and warrants are listed on the Nasdaq Capital Market under the symbols “REVB” and “REVBW”, respectively. Reverse Stock Split On January 25, 2024, the Company effected the approved 1-for-30 reverse stock split of our shares of common stock. Unless specifically provided otherwise herein, the share and per share information that follows in this Quarterly Report, reflects the effect of the reverse stock split. Liquidity and Capital Resources Going Concern The Company has incurred recurring losses since its inception, including a net loss of $2.7 million for the three months ended March 31, 2024. As of March 31, 2024, the Company had an accumulated deficit of $28.1 million, a stockholders’ equity of $9.5 million and available cash and cash equivalents of $14.6 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 GEM-AKI, GEM-CKD, GEM-SSI or other product candidates, which the Company 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 sustain operations within one-year after the date that the Company’s unaudited financial statements for March 31, 2024 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 unaudited consolidated financial statements for March 31, 2024, 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. Basis of Presentation 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.

Summary of Significant Accounting Policies |
2. Summary of Significant Accounting Policies Unaudited Interim Condensed Consolidated Financial Statements The unaudited interim consolidated financial statements have been prepared on the same basis as the audited financial statements as of December 31, 2023 and for the year ended December 31, 2023 and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s financial position. The financial data and the other financial information contained in these notes to the consolidated financial statements related to the three months ended March 31, 2024 are unaudited. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any other future annual or interim period. The consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended December 31, 2023 included on Form 10-K, as filed with the SEC on March 22, 2024. The accompanying consolidated balance sheet as of December 31, 2023 has been derived from the audited balance sheet at December 31, 2023 contained in the above referenced Form 10-K. Use of Estimates The preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of expenses. These estimates and assumptions are based on the Company’s best estimates and judgment. The Company regularly evaluates its estimates and assumptions using historical and industry experience and other factors; however, actual results could differ materially from these estimates and could have an adverse effect on the Company’s consolidated financial statements. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. The Company maintains its cash in checking and savings accounts. Income generated from cash held in savings accounts is recorded as interest income. The carrying value of the Company’s savings accounts is included in cash and approximates the fair value. Concentrations of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents. Bank deposits are held by accredited financial institutions and these deposits may at times be in excess of federally insured limits. The Company limits its credit risk associated with cash and cash equivalents by placing them with financial institutions that it believes are of high quality. The Company has not experienced any losses on its deposits of cash or cash equivalents. Deferred Offering Costs The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings as deferred offering costs until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds generated as a result of the offering. Should the planned equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the consolidated statements of operations. Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which is five years. Maintenance and repairs are charged to operating expense as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any gain or loss is included in other (expense) income. Leases The Company determines if an arrangement is a lease at inception. Lease right-of-use assets represent the right to use an underlying asset for the lease 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 similar 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 product candidates, GEM-AKI, GEM-CKD, GEM-SSI and other product candidates. 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 Company’s behalf. 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. Estimates are based on factors such as the work completed, including the level of patient enrollment. The Company monitors patient enrollment levels and related activity to the extent reasonably possible and makes judgments and estimates in determining the accrued balance in each reporting period. The 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 uncertain. These costs are recorded in general and administrative expenses in the consolidated statements of operations. Stock-based Compensation The Company recognizes stock-based compensation expense related to stock options, third-party warrants, and Restricted Stock Unit (“RSU”) awards granted, based on the estimated fair value of the stock-based awards on the date of grant. The fair value of employee stock options and third-party warrants are generally determined using the Black-Scholes option-pricing model using various inputs, including estimates of historic volatility, term, risk-free rate, and future dividends. The grant date fair value of the stock-based awards, which have graded vesting, is recognized using the straight-line method over the requisite service period of each stock-based award, which is generally the vesting period of the respective stock-based awards. The Company recognizes forfeitures as they occur. Income Taxes Income taxes 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 financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates applied to taxable income in the years in which those temporary differences are expected to be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or loss in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized. Interest and penalties related to unrecognized tax benefits are included within the provision of income tax. To date, there have been no unrecognized tax benefits balances. Fair Value Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company’s valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company follows a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. These levels of inputs are the following: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company has determined that the measurement of the fair value of the Class C Common Stock Warrants (as defined in Note 5) is a Level 3 fair value measurement and uses the Monte-Carlo simulation model for valuation (see Note 10). Warrant Liability The Company reviews the terms of debt instruments, equity instruments, and other financing arrangements to determine whether there are embedded derivative features, including embedded conversion options that are required to be bifurcated and accounted for separately as a derivative financial instrument. Additionally, in connection with the issuance of financing instruments, the Company may issue freestanding options and warrants. The Company accounts for its common stock warrants in accordance with ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). Based upon the provisions of ASC 480 and ASC 815, the Company accounts for common stock warrants as current liabilities if the warrant fails the equity classification criteria. Common stock warrants classified as liabilities are initially recorded at fair value on the grant date and remeasured at each balance sheet date with the offsetting adjustments recorded in change in fair value of warrant liabilities within the consolidated statements of operations. The Company values its Class C Common Stock Warrants classified as liabilities using the Monte-Carlo simulation model. Basic and Diluted Net (Loss) Earnings per Share Basic net (loss) earnings per share is calculated by dividing net (loss) income by the weighted-average number of shares of common stock outstanding during the period, without consideration of potential shares of common stock. Diluted net (loss) earnings per share is calculated by dividing net (loss) income by the weighted-average number of shares of common stock outstanding plus potential shares of common stock. Convertible preferred stock on an as converted basis, RSU awards, warrants and stock options outstanding are considered potential shares of common stock and are included in the calculation of diluted net (loss) earnings per share using the treasury stock method when their effect is dilutive. Potential shares of common stock are excluded from the calculation of diluted net (loss) earnings per share when their effect is anti-dilutive. As of March 31, 2024, there were 30,466 potential shares of common stock, respectively, (see Note 8), that were excluded from the calculation of diluted net loss per share because their effect was anti-dilutive. For the three months ended March 31, 2023, there were 30,839 million potential common shares that were included in the calculation of diluted net earnings per share, which consists of: (i) 28,099 shares of common stock issuable upon the alternative cashless exercise of the Class C Common Stock Warrants; (ii) 2,496 Class C Pre-Funded Warrants; and (iii) 244 Rollover RSU awards. For the three months ended March 31, 2023, the basic and diluted weighted-average shares used to compute net earnings per share in the unaudited consolidated statements of operations includes the shares issued from the reverse stock split fractional share round up. Comprehensive (Loss) Income The Company has no components of comprehensive (loss) income other than net (loss) income. Thus, comprehensive (loss) income is the same as net (loss) income for the periods presented. Segment Reporting Operating segments are defined as components of an entity about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources in assessing performance. The Company has one operating segment. The Company’s chief operating decision maker manages the Company’s operations for the purposes of allocating resources and evaluating financial performance. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. The Company has evaluated recently issued accounting pronouncements and does not believe any will have a material impact on the Company’s consolidated financial statements or related financial statement disclosures.

Commitments and Contingencies |
4. Commitments and Contingencies Lease Commitments The Company leases 2,140 square feet of laboratory space located at 11011 Torreyana Road, Suite 102, San Diego, California (the “Lease”). In January 2024, the Company signed an amendment extending the Lease until November 30, 2024, with a base monthly rent equal to $5,350. The Company is required to maintain a security deposit of $5,564. The Lease contains customary default provisions, representations, warranties and covenants. In addition to rent, the Lease requires the Company to pay certain taxes, insurance and operating costs relating to the leased premises. The Company has applied the short-term lease exception as the amendment is less than twelve months. The Lease is classified as an operating lease. Rent expense was $16,050 for the three months ended March 31, 2024 and $24,991 for the three months ended March 31, 2023, respectively. Future minimum lease payments under the operating lease as of March 31, 2024 is $42,800. Commitments The Company enters into contracts in the normal course of business with third party service providers and vendors. These contracts generally provide for termination on notice and, therefore, are cancellable contracts and not considered contractual obligations and commitments. Contingencies From time to time, the Company may become subject to claims and litigation arising in the ordinary course of business. The Company is not a party to any material legal proceedings, nor is it aware of any material pending or threatened litigation other than described below. Legal Proceedings On February 18, 2022, LifeSci Capital LLC filed an action against the Company in the U.S. District Court for the Southern District of New York seeking damages in the amount of approximately $5.3 million plus interest for unpaid banking and advisory fees. These fees arise under contracts which were entered into prior to the Business Combination and the Company has asserted that LifeSci Capital LLC is not entitled to the fee because it violated its responsibilities by misrepresenting to Petra the funds that would be available following the Business Combination, absent which Petra would not have entered into the Business Combination Agreement. This action remains pending as of the date of this report. $1.5 million of the claim relates to deferred underwriting commissions from the Petra initial public offering, which are recorded as a current liability in the financial statements as of March 31, 2024 under deferred underwriting commissions. On December 1, 2023 a Magistrate Judge issued a report recommending summary judgment in favor of LifeSci Capital LLC. On December 15, 2023, the Company filed objections to the Magistrate’s report asserting that the Magistrate Judge made factual determinations not appropriate for summary judgment and misapplied the law. The Magistrate’s report is a recommendation to the trial judge who is responsible for reviewing the case de novo. Other than the deferred underwriting commissions, no liabilities are reflected in the financial statements as the amount of any additional liability cannot be determined at this time.

Stock-Based Compensation

Share-Based Payment Arrangement [Abstract] |
|
Stock-Based Compensation |
. Stock-Based Compensation 2021 Equity Incentive Plan In January 2022, in connection with the Business Combination, the Board of Directors and the Company’s stockholders adopted the 2021 Equity Incentive Plan (the “2021 Plan”) and reserved 1,232 authorized shares of common stock for issuance under the plan. 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, and began on January 1, 2022, by 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 July 14, 2023 at the Company’s 2023 Annual Meeting of Stockholders, an amendment to the 2021 Equity Incentive Plan to increase the number of shares reserved under the Plan to 21,623 was approved. 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. As of March 31, 2024, there were 20,466 shares available for future grants under the 2021 Plan. Restricted Stock Units At 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 25% on the one-year anniversary and the remainder vesting monthly thereafter for grants to officers, employees and consultants. The milestone-based vesting conditions vested on the Closing Date of the Business Combination. As of March 31, 2024 and December 31, 2023, the Company has a total of 94 Rollover RSU awards for shares of common stock outstanding, respectively. As of March 31, 2024, 61 Rollover RSU awards have fully vested but are unissued and no Rollover RSU awards have been forfeited. As of March 31, 2024, 94 Rollover RSU awards will vest and be issued over the next 0.9 years. Each Rollover RSU award converts to one share of common stock. Stock Options The Company has granted stock options which (i) vest fully on the date of grant; (ii) vest 25% on the one-year anniversary of the grant date or the employees hiring date, with the remainder vesting quarterly thereafter; or (iii) vest quarterly over one-year, for grants to Board of Directors, officers and employees. Stock options have a maximum term of 3 or 10 years. The activity related to stock options during the three months ended March 31, 2024 is summarized as follows:

For the three months ended March 31, 2024, the weighted-average Black-Scholes value per stock option was $314.03. The fair value of the stock options was estimated using the Black-Scholes option pricing model with the following weighted-average assumptions:
|
|
|
|
|
Volatility |
|
|
126.0 |
% |
Expected term (years) |
|
|
5.03 |
|
Risk-free interest rate |
|
|
3.09 |
% |
Expected dividend yield |
|
|
0.0 |
% |
Expected volatility is based on the historical volatility of shares of the Company’s common stock. 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 For the three months ended March 31, 2024 and 2023, the Company recorded stock-based compensation expense for the period indicated as follows:

The Public Warrants trade on the Nasdaq Capital Market under the ticker symbol REVBW. The Company may redeem the Public Warrants at a price of $0.01 per Public Warrant upon not less than 30 days’ prior written notice of redemption if, and only if, the reported last sale price of the Company’s common stock equals or exceeds $18,900.00 per share for any 20 trading days within a 30-trading day period ending on the third business day prior to the notice of redemption to the Public Warrant holders; and if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying the Public Warrants. If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. Rollover Warrants Prior to the Merger, Revelation Sub issued warrants to a placement agent to purchase up to 157 shares of common stock with an exercise price of $2,816.92 per share which expire on January 31, 2027, valued on the issuance date in the aggregate at $326,675.

Class C Pre-Funded Warrants In connection with the February 2023 Public Offering, the Company issued pre-funded warrants to purchase up to 11,214 shares of common stock at an exercise price of $0.003 per share. Between February 14, 2023 and April 6, 2023, the Company received notices of cash exercise for the Class C Pre-Funded Warrants issued in connection with the February 2023 Public Offering for 336,400 shares of common stock at a total purchase price of $33.64. As of March 31, 2024, there were no Class C Pre-Funded Warrants outstanding. Class C Common Stock Warrants In connection with the February 2023 Public Offering, the Company issued 6,450,000 warrants to purchase up to 215,000 shares of common stock at an exercise price of $160.80 per share, valued on the public offering purchase date in the aggregate at $13,996,500 and included in the issuance costs of the public offering and treated as a liability . The warrants were exercisable immediately upon issuance, provide for a cash, cashless exercise right or an alternative cashless exercise right for 0.4 shares of common stock per Class C Common Stock Warrant and expire on February 14, 2028. The Company evaluated the Class C Common Stock Warrants under ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity (“ASC 815-40”) and concluded that they do not meet the criteria to be classified in stockholders’ equity and accounted for the Class C Common Stock Warrants as current liabilities. The Company concluded that the multiplier of 0.4 shares of common stock per Class C Common Stock Warrant used in the alternative cashless exercise precludes the Class C Common Stock Warrants from being considered indexed to the Company’s stock. The Company recorded the Class C Common Stock Warrants as current liabilities on the balance sheet at fair value, with subsequent changes in their respective fair values recognized in the consolidated statements of operations at each reporting date. Estimating fair values of liability-classified financial instruments requires the development of estimates that may, and are likely to, change over the duration of the instrument with related changes in internal and external market factors. In addition, option-based techniques are highly volatile and sensitive to changes in the trading market price of the Company’s common stock. Because liability-classified financial instruments are initially and subsequently carried at fair value, the Company’s financial results will reflect the volatility in these estimate and assumption changes. Changes in fair value are recognized as a component of other (expense) income in the consolidated statements of operations. At the date of issuance, the Company valued the Class C Common Stock Warrants using a Monte-Carlo simulation model with a fair value of $14.0 million. As of March 31, 2024, the Company received notices of alternative cashless exercises for 6,217,640 Class C Common Stock Warrants issued in connection with the February 2023 Public Offering for 82,919 shares of common stock. As of March 31, 2024, the Company re-valued 232,360 outstanding Class C Common Stock Warrants to purchase up to 7,746 shares of common stock using a Monte-Carlo simulation model with a fair value of $15,260.0 million. For the three months ended March 31, 2024, the gain of $0.1 million, respectively, resulting from the change in the fair value of the liability for the unexercised warrants was recorded as a change in fair value of the warrant liability in the accompanying consolidated statements of operations for the three months ended March 31, 2024. As part of the February 2024 Public Offering, the exercise price of the Class C Common Stock Warrants issued in the February 2023 Public Offering was reset from $160.80 to $4.53. Class D Pre-Funded Warrants In connection with the February 2024 Public Offering, the Company issued pre-funded warrants to purchase up to 1,236,530 shares of common stock at an exercise price of $0.0001 per share. Between February 5, 2024 and February 13, 2024, the Company received notices of cash exercise for the Class D Pre-Funded Warrants issued in connection with the February 2024 Public Offering for 1,236,530 shares of common stock at a total purchase price of $123.65. As of March 31, 2024, there were no Class D Pre-Funded Warrants outstanding. Class D Common Stock Warrants In connection with the February 2024 Public Offering, the Company issued and has outstanding 2,730,000 warrants shares of common stock at an exercise price of $4.53 per share, valued on the public offering purchase date in the aggregate at $6.3 million and included in the issuance costs of the public offering and treated as equity. The warrants were exercisable immediately upon issuance, provide for a cash or cashless exercise right and expire on February 5, 2029. The fair value of the Class D Common Stock Warrants were estimated using the Black-Scholes option pricing model with the following assumptions:

Income Taxes |
11. Income Taxes The quarterly provision for or benefit from income taxes is computed based upon the estimated annual effective tax rate and the year-to-date pre-tax (loss) income and other comprehensive (loss) income. The Company did not record a provision or benefit for income taxes during the three months ended March 31, 2024 and 2023, respectively. For the three months ended March 31, 2024 and 2023, the Company recorded non-taxable income of $0.1 million and $7.7 million, respectively, related to a change in the fair value of a warrant liability. The Company incurred taxable losses in 2023 and projects further taxable losses for 2024. The Company did not record a benefit from income taxes because, based on evidence involving its ability to realize its deferred tax assets, the Company recorded a full valuation allowance against its deferred tax assets.

Summary of Significant Accounting Policies (Policies)
|
3 Months Ended |
Mar. 31, 2024 |
Accounting Policies [Abstract] |
|
Use of Estimates |
Use of Estimates The preparation of the consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of expenses. These estimates and assumptions are based on the Company’s best estimates and judgment. The Company regularly evaluates its estimates and assumptions using historical and industry experience and other factors; however, actual results could differ materially from these estimates and could have an adverse effect on the Company’s consolidated financial statements.
|
Cash and Cash Equivalents |
Cash and Cash Equivalents The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. The Company maintains its cash in checking and savings accounts. Income generated from cash held in savings accounts is recorded as interest income. The carrying value of the Company’s savings accounts is included in cash and approximates the fair value.
|
Concentration of Credit Risk |
Concentrations of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents. Bank deposits are held by accredited financial institutions and these deposits may at times be in excess of federally insured limits. The Company limits its credit risk associated with cash and cash equivalents by placing them with financial institutions that it believes are of high quality. The Company has not experienced any losses on its deposits of cash or cash equivalents.
|
Deferred Offering Costs |
Deferred Offering Costs The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings as deferred offering costs until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds generated as a result of the offering. Should the planned equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the consolidated statements of operations.
|
Property and Equipment, Net |
Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which is five years. Maintenance and repairs are charged to operating expense as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any gain or loss is included in other (expense) income.
|
Leases |
Leases The Company determines if an arrangement is a lease at inception. Lease right-of-use assets represent the right to use an underlying asset for the lease 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 similar 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 Research and development expenses consist primarily of costs incurred for the development of the Company’s product candidates, GEM-AKI, GEM-CKD, GEM-SSI and other product candidates. 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 Company’s behalf. 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. Estimates are based on factors such as the work completed, including the level of patient enrollment. The Company monitors patient enrollment levels and related activity to the extent reasonably possible and makes judgments and estimates in determining the accrued balance in each reporting period. The 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 |
Patent Costs Legal costs in connection with approved patents and patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. These costs are recorded in general and administrative expenses in the consolidated statements of operations.
|
Stock-based Compensation |
Stock-based Compensation The Company recognizes stock-based compensation expense related to stock options, third-party warrants, and Restricted Stock Unit (“RSU”) awards granted, based on the estimated fair value of the stock-based awards on the date of grant. The fair value of employee stock options and third-party warrants are generally determined using the Black-Scholes option-pricing model using various inputs, including estimates of historic volatility, term, risk-free rate, and future dividends. The grant date fair value of the stock-based awards, which have graded vesting, is recognized using the straight-line method over the requisite service period of each stock-based award, which is generally the vesting period of the respective stock-based awards. The Company recognizes forfeitures as they occur.
|
Income Taxes |
Income Taxes Income taxes 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 financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates applied to taxable income in the years in which those temporary differences are expected to be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or loss in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized. Interest and penalties related to unrecognized tax benefits are included within the provision of income tax. To date, there have been no unrecognized tax benefits balances.
|
Fair Value |
Fair Value Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company’s valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company follows a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. These levels of inputs are the following: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company has determined that the measurement of the fair value of the Class C Common Stock Warrants (as defined in Note 5) is a Level 3 fair value measurement and uses the Monte-Carlo simulation model for valuation (see Note 10).
|
Warrant Liability |
Warrant Liability The Company reviews the terms of debt instruments, equity instruments, and other financing arrangements to determine whether there are embedded derivative features, including embedded conversion options that are required to be bifurcated and accounted for separately as a derivative financial instrument. Additionally, in connection with the issuance of financing instruments, the Company may issue freestanding options and warrants. The Company accounts for its common stock warrants in accordance with ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). Based upon the provisions of ASC 480 and ASC 815, the Company accounts for common stock warrants as current liabilities if the warrant fails the equity classification criteria. Common stock warrants classified as liabilities are initially recorded at fair value on the grant date and remeasured at each balance sheet date with the offsetting adjustments recorded in change in fair value of warrant liabilities within the consolidated statements of operations. The Company values its Class C Common Stock Warrants classified as liabilities using the Monte-Carlo simulation model.
|
Basic and Diluted Net Loss per Share |
Basic and Diluted Net (Loss) Earnings per Share Basic net (loss) earnings per share is calculated by dividing net (loss) income by the weighted-average number of shares of common stock outstanding during the period, without consideration of potential shares of common stock. Diluted net (loss) earnings per share is calculated by dividing net (loss) income by the weighted-average number of shares of common stock outstanding plus potential shares of common stock. Convertible preferred stock on an as converted basis, RSU awards, warrants and stock options outstanding are considered potential shares of common stock and are included in the calculation of diluted net (loss) earnings per share using the treasury stock method when their effect is dilutive. Potential shares of common stock are excluded from the calculation of diluted net (loss) earnings per share when their effect is anti-dilutive. As of March 31, 2024, there were 30,466 potential shares of common stock, respectively, (see Note 8), that were excluded from the calculation of diluted net loss per share because their effect was anti-dilutive. For the three months ended March 31, 2023, there were 30,839 million potential common shares that were included in the calculation of diluted net earnings per share, which consists of: (i) 28,099 shares of common stock issuable upon the alternative cashless exercise of the Class C Common Stock Warrants; (ii) 2,496 Class C Pre-Funded Warrants; and (iii) 244 Rollover RSU awards. For the three months ended March 31, 2023, the basic and diluted weighted-average shares used to compute net earnings per share in the unaudited consolidated statements of operations includes the shares issued from the reverse stock split fractional share round up.
|
Comprehensive (Loss) Income |
Comprehensive (Loss) Income The Company has no components of comprehensive (loss) income other than net (loss) income. Thus, comprehensive (loss) income is the same as net (loss) income for the periods presented.
|
Segment Reporting |
Segment Reporting Operating segments are defined as components of an entity about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources in assessing performance. The Company has one operating segment. The Company’s chief operating decision maker manages the Company’s operations for the purposes of allocating resources and evaluating financial performance.
|
Recent Accounting Pronouncements |
Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. The Company has evaluated recently issued accounting pronouncements and does not believe any will have a material impact on the Company’s consolidated financial statements or related financial statement disclosures.

- DefinitionThe estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.

- DefinitionThe estimated amount of dividends to be paid to holders of the underlying shares (expected dividends) over the option's term. Dividends are taken into account because payment of dividends to shareholders reduces the fair value of the underlying shares, and option holders generally do not receive dividends.

- DefinitionThe estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
