**Notes to the Unaudited Condensed Consolidated Financial Statements**

**1. Organization and Basis of Presentation**

Revelation Biosciences, Inc. (collectively with its wholly-owned subsidiaries, referred to as "we," us," "our," "Revelation," or the "Company") is a clinical-stage life science company that is focused on rebalancing inflammation to optimize health using its proprietary formulation Gemini. We have multiple ongoing programs to evaluate Gemini, including GEM-AKI as a prevention for acute kidney injury ("AKI"), GEM-CKD as a treatment for chronic kidney disease ("CKD"), and GEM-PSI as a prevention for post surgical infection ("PSI") (together the "Product Candidates"). The Company was incorporated in the state of Delaware on November 20, 2019 (originally as Petra Acquisition, Inc.) and is based in San Diego, California.

The Company's common stock and public warrants are listed on the Nasdaq Capital Market under the symbols "REVB" and "REVBW", respectively.

***Reverse Stock Split***

On January 28, 2025, the Company effected the approved 1-for-16 reverse stock split of our shares of common stock.

On July 7, 2025, the Company effected the approved 1-for-3 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 splits.

***Liquidity and Capital Resources***

*Going Concern*

The Company has incurred recurring losses since its inception, including a net loss of $4.5 million for the six months ended June 30, 2025. As of June 30, 2025, the Company had an accumulated deficit of $45.0 million, a stockholders' equity of $3.8 million and available cash and cash equivalents of $5.2 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 Product Candidates 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 June 30, 2025 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 condensed consolidated financial statements for June 30, 2025, 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"). The condensed consolidated financial statements include the accounts of Revelation Biosciences, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions among the consolidated entity have been eliminated in consolidation.

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited financial statements as of December 31, 2024 and for the year ended December 31, 2024 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 condensed consolidated financial statements related to the three and six months ended June 30, 2025 are unaudited. The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2025 or for any other future annual or interim period. The condensed 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, 2024 included on Form 10-K, as filed with the SEC on March 6, 2025. The accompanying condensed consolidated balance sheet as of December 31, 2024 has been derived from the audited balance sheet at December 31, 2024 contained in the above referenced Form 10-K.

**2. Summary of Significant Accounting Policies**

During the three and six months ended June 30, 2025, there were no changes to the Company's significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2024. Selected significant accounting policies are discussed in further detail below:

***Use of Estimates***

The preparation of the condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions about future events that affect the 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 condensed consolidated financial statements.

***Basic and Diluted Net Loss per Share***

Basic and diluted net loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. In net loss periods, basic net loss per share and diluted net loss per share are identical because the otherwise dilutive potential common shares become anti-dilutive and are therefore excluded. As of June 30, 2025 and 2024, there were 6,724,423 and 57,504 potential shares of common stock excluded from the calculation of diluted net loss per share as their effect is anti-dilutive, respectively. The basic weighted-average shares used to compute net loss per share in the unaudited condensed consolidated statements of operations includes 1 share underlying Rollover RSU's that have vested but are unissued and 41,668 shares underlying the outstanding Class F Common Stock Warrants as exercised via the alternative cashless exercise because their exercise requires only nominal consideration for delivery of the shares.

***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 condensed consolidated financial statements or related financial statement disclosures.

---

**4. Commitments and Contingencies**

***Lease Commitments***

The Company leases office space located at 4660 La Jolla Village Dr., Suite 100, San Diego, California, through a month-to-month rental agreement, with monthly rent of $151. In addition, the Company leases 2,140 square feet of laboratory space located at 11011 Torreyana Road, Suite 102, San Diego, California on a month-to-month basis with monthly rent of $5,350 per month.

***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.

**5. Financings**

***February 2024 Public Offering***

***2021 Equity Incentive Plan***

In January 2022, the Board of Directors and the Company's stockholders adopted the 2021 Equity Incentive Plan (the "2021 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 immediately or within four years. In addition, the number of shares of stock available for issuance under the 2021 Plan will be automatically increased on the first day of each quarter by 10% of the aggregate number of fully diluted shares of our common stock from the last day of the preceding quarter to the first day of the current quarter or such lesser number as determined by our board of directors (the "Evergreen").

On January 1, 2025, the number of shares of common stock available under the 2021 Plan increased to 52,173 as per the Evergreen in the 2021 Plan.

Under the 2021 Plan, stock options and stock appreciation rights are granted at exercise prices determined by the Board of Directors which cannot be less than 100% of the estimated fair market value of the common stock on the grant date. Incentive stock options granted to any stockholders holding 10% or more of the Company's equity cannot be granted with an exercise price of less than 110% of the estimated fair market value of the common stock on the grant date and such options are not exercisable after five years from the grant date.

As of June 30, 2025 and December 31, 2024, the fair value of the Class C Common Stock Warrants was $786 and $2,246, respectively, using a Black-Scholes model and Monte-Carlo simulation model as of June 30, 2025 and December 31, 2024, respectively.

The Class D Common Stock Warrants were valued on the issuance date in the aggregate at $6.3 million and included in the issuance costs of the offering and treated as equity. As part of the reverse stock split on January 28, 2025, the exercise price of the Class D Common Stock Warrants was reset from $48.00 to $11.28. The exercise price was further reset to $3.30 on May 29, 2025 as a result of the down-round provision in the Class D Common Stock Warrants triggered by instruments sold in the May 2025 Public Offering (see Note 5 above). The impact of the down-round trigger for the Class D Common Stock Warrants was not significant to the Company's condensed consolidated financial statements for the three and six months ended June 30, 2025.

---

| | |

As of June 30, 2025, there are 21,502 Class E Common Stock Warrants outstanding to purchase 21,502 shares of common stock.

The fair value of the Class E Common Stock Warrants were estimated using the Black-Scholes option pricing model with the following assumptions:

---

As part of the reverse stock split on January 28, 2025, common stock underlying the Class G Common Stock Warrants was adjusted from 127,001 shares of common stock to 540,488 shares of common stock and the exercise price was reset from $48.00 to $11.28.

On May 29, 2025, as a result of the down-round provision in the Class G Common Stock Warrants triggered by instruments sold in the May 2025 Public Offering (see Note 5 above), the Class G Common Stock Warrants were reset to an exercise price of $3.30 per warrant, and there was a corresponding increase in the common stock underlying the Class G Common Stock Warrants to 1,847,273 shares. The Company recorded a deemed dividend of approximately $3.2 million, which represents the incremental fair value of the outstanding warrants as a result of the down-round provision and is measured as the difference between the warrants' fair value using an exercise price of $11.28 per share and an exercise price of $3.30 per share. As the Company has an accumulated deficit, the deemed dividend was recorded as a reduction in additional paid-in capital, resulting in a net impact of zero to additional paid-in capital in the accompanying condensed consolidated balance sheet.

The fair values of the Class G Common Stock Warrants on May 29, 2025, with an exercise price of $11.28 per share and $3.30 per share were $2.12 per warrant share and $2.34 per warrant share, respectively, and was estimated using the Black-Scholes option pricing model with the following assumptions:

For the six months ended June 30, 2025 and 2024, the Company recorded non-taxable income of $1,460 and $0.1 million, respectively, related to a change in the fair value of a warrant liability. The Company incurred taxable losses in 2024 and projects further taxable losses for 2025.

**11. Segment Information**

ASC 280, "Segment Reporting," establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate discrete financial information is available that is evaluated regularly by the chief operating decision maker ("CODM") in deciding how to allocate resources and in assessing performance. The Company and the Company's CODM view the Company's operations and manage its business on the basis of one reportable segment, which is focused on the prevention and treatment of disease by developing and commercializing therapeutics that modulate the innate immune system.

The CODM of the Company is the Chief Executive Officer. The CODM assesses the performance of the Company and decides how to allocate resources based upon consolidated net loss that is also reported within the condensed consolidated statements of operations. The measure of segment assets that is reviewed by the CODM is reported within the condensed consolidated balance sheets as consolidated total assets. The CODM uses consolidated net loss to monitor period-over-period results and decides where to allocate and invest additional resources within the business to continue growth. The following is a summary of the significant expense categories and consolidated net loss details provided to the CODM:

Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Form 10-Q, the Company's Form 10-K for the fiscal year ended December 31, 2024 and in the Company's registration statements filed under the Securities Act of 1933, as amended, particularly under the "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements and Risk Factors Summary" sections.*

**Overview**

Revelation is a clinical-stage life science company that is focused on rebalancing inflammation to optimize health using its proprietary formulation Gemini. We are developing a pipeline of potential high-value products based on Gemini. Gemini is our proprietary formulation of PHAD an established TLR4 agonist that can stimulate the human body's innate immune response to prevent and treat disease. Our current Gemini based programs consist of: GEM-AKI, which is being developed as a potential therapy for the prevention and treatment of acute kidney injury; GEM-CKD, which is being developed as a potential therapy for the prevention and treatment of chronic kidney disease; GEM-PSI, which is being developed for the prevention and treatment of post surgical infection; and GEM-PBI as a prevention of infection in severe burn patients requiring hospitalization (together the "Product Candidates").

Since our inception, we have devoted substantially all of our resources to organizing and staffing our Company, business planning, raising capital, and research and development of the Product Candidates.

We have funded our operations since our inception to June 30, 2025 through the issuance and sale of our capital stock, from which we have raised net proceeds of $60.2 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 audited financial statements for June 30, 2025 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 $4.5 million for the six months ended June 30, 2025 and $11.1 million for the six months ended June 30, 2024. As of June 30, 2025 we had an accumulated deficit of $45.0 million. We expect to continue to generate operating losses and negative operating cash flows for the foreseeable future if and as we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•continue the research and development of our product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•initiate clinical studies for, or preclinical development of, our product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•further develop and refine the manufacturing processes of our product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•change or add manufacturers or suppliers of product candidate materials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•seek regulatory and marketing authorizations for any of our product candidates that successfully complete development;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•acquire or license other product candidates, technologies or biological materials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•make milestone, royalty or other payments under future license agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•obtain, maintain, protect and enforce our intellectual property portfolio;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•seek to attract and retain new and existing skilled personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•create additional infrastructure to support our operations as a public company and incur increased legal, accounting, investor relations and other expenses; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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 Product Candidates 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 Product Candidates 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**

*One Big Beautiful Bill Act*

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing its impact on its consolidated financial statements, which are expected to be immaterial.

*Reverse Stock Splits*

On January 28, 2025, the Company effected a 1-for-16 reverse stock split of our outstanding shares of common stock, which had been approved at a special meeting of stockholders. Additionally, on July 7, 2025, the Company effected the approved 1-for-3 reverse stock split of our shares of common stock.

***Research and Development***

Research and development expenses consist primarily of costs incurred for the development of our product candidates. 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 Product Candidates 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 Product Candidates 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 Product Candidates 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, regulatory and staffing developments at the FDA 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 Product Candidates 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 settlement expenses with A-IR Clinical Research Ltd., foreign currency transaction gains and losses, interest expense and interest income from our cash balances in savings accounts.

---

Research and development expenses decreased by $0.1 million, from $1.4 million for the three months ended June 30, 2024 to $1.3 million for the three months ended June 30, 2025. The decrease was primarily due to a decrease of other research and development expenses.

Research and development expenses increased by $0.1 million, from $2.1 million for the six months ended June 30, 2024 to $2.2 million for the six months ended June 30, 2025. The increase was primarily due to increases of $0.1 million of clinical study expense and $0.1 million of personnel expenses, offset by a decrease of $0.1 million of other research and development expenses.

<u>General and Administrative Expenses</u>

General and administrative expenses for the three months ended June 30, 2025 and 2024 were $1.1 million for both periods.

General and administrative expenses increased by $0.1 million, from $2.3 million for the six months ended June 30, 2024 to $2.4 million for the six months ended June 30, 2025. The increase was primarily due to increases of $0.1 million in legal and professional fees.

<u>Other (Expense) Income, Net</u>

Other (expense) income, net was expense of $5.9 million for the three months ended June 30, 2024, primarily related to the clinical trial related settlement expenses with A-IR Clinical Research Ltd., offset by interest income from our cash balances in savings accounts. Other (expense) income, net, was minimal for the three months ended June 30, 2025.

Other (expense) income, net, was expense of $6.6 million for the six months ended June 30, 2024, primarily related to the change in fair value of the warrant liability, the clinical trial related settlement expenses with A-IR Clinical Research Ltd., foreign currency transaction gains and losses, and interest income from our cash balances in savings accounts. Other (expense) income, net,

------

was income of $0.06 million for the six months ended June 30, 2025, primarily 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.

**Liquidity and Capital Resources**

Since our inception to June 30, 2025, 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 $60.2 million. As of June 30, 2025, we had available cash and cash equivalents of $5.2 million and an accumulated deficit of $45.0 million.

Our use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to our Product Candidates. 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 $4.5 million for the six months ended June 30, 2025. As of June 30, 2025 we had an accumulated deficit of $45.0 million, a stockholders' equity of $3.8 million and available cash and cash equivalents of $5.2 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 Product Candidates 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 audited financial statements for June 30, 2025 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 June 30, 2025, 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.

***Cash Flows***

The following table summarizes our cash flows for the periods presented:

---

| | | |
|:---|:---|:---|
|  | **Six Months Ended<br>June 30,** | **Six Months Ended<br>June 30,** |
|  | **2025** | **2024** |
| Net cash used in operating activities | $(4713688) | $(5316651) |
| Net cash used in investing activities | - | (19172) |
| Net cash provided by financing activities | 3388541 | 5417180 |
| Net (decrease) increase in cash and cash equivalents | $(1325147) | $81357 |

---

***Net Cash Used in Operating Activities***

During the six months ended June 30, 2025, net cash used in operating activities was $4.7 million, which consisted of a net loss of $4.5 million and a net change of $0.2 million comprised of the change in fair value of the warrant liability, stock-based compensation expense and depreciation expense, offset by a net change of $0.5 million in our net operating assets and liabilities.

During the six months ended June 30, 2024, net cash used in operating activities was $5.3 million, which consisted of a net loss of $11.1 million and a net change of $0.03 million comprised of the change in fair value of the warrant liability, stock-based compensation expense and depreciation expense, offset by a net change of $5.7 million in our net operating assets and liabilities.

***Net Cash Used in Investing Activities***

During the six months ended June 30, 2025, there was no net cash provided by or used in investing activities.

During the six months ended June 30, 2024, net cash used in investing activities consisted of the purchase of lab equipment.

***Net Cash Provided by Financing Activities***

During the six months ended June 30, 2025, net cash provided by financing activities was $3.4 million from the May 2025 Public Offering.

During the six months ended June 30, 2024, net cash provided by financing activities was $5.4 million from the February Public Offering.

**Contractual Obligations and Other Commitments**

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 June 30, 2025, 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.

**Critical Accounting Policies and Significant Judgments 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 generally accepted accounting principles in the United States ("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.

------

**Recent Accounting Pronouncements**

See Note 2 to our unaudited condensed 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.

**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 June 30, 2025, 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 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 SEC'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.**

None.

**Item 1A. Risk Factors.**

Our business is subject to various risks, including those described below and in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024.

***Significant reductions in FDA staffing and changes in federal regulatory policy may delay or adversely affect the approval and commercialization of our product candidates.***

Recent actions by the current administration, including substantial reductions in the workforce of the U.S. Food and Drug Administration ("FDA"), have created increased uncertainty regarding the timing and outcome of regulatory reviews for new drugs and biologics. These staffing cuts, which have affected key divisions responsible for the review of innovative therapies, may result in longer review times, missed milestones, and inconsistent or delayed feedback from the agency. In addition, the loss of experienced FDA personnel and potential further restructuring could lead to a loss of institutional knowledge and a reduced ability to resolve complex regulatory questions efficiently.

As a result, we may experience delays in the initiation, conduct, or completion of our clinical trials and in the review and approval of our marketing applications. These delays could adversely impact our ability to bring our product candidates to market, disrupt our development timelines, and increase our costs. Furthermore, ongoing regulatory uncertainty may negatively affect investor confidence and our ability to raise additional capital on favorable terms, particularly as small and mid-cap biopharmaceutical companies are more vulnerable to such disruptions.

If the FDA's operational capacity continues to be reduced or if further policy changes are implemented that affect the agency's review processes, our business, financial condition, and results of operations could be materially and adversely affected.

------

***Artificial intelligence is playing an increasingly important role in biotechnology which may have an effect on us.***

Artificial intelligence ("AI") is increasingly playing a role in our industry, being used for target identification, drug discovery, preclinical modeling, and data analysis. While it is not a significant factor in our current operations, AI may play a future role in our operations based upon our evaluation of its usefulness to us, and there are material risks associated with its use.

AI technologies are inherently complex and evolving. They may not function as intended, produce accurate results, or provide actionable insights. The quality of AI outputs depends heavily on the quality and quantity of input data, which in the life sciences context may be limited, biased, incomplete, or subject to regulatory and privacy constraints. If we utilize AI in the future and our AI systems fail to identify viable therapeutic candidates, predict biological outcomes, or produce reproducible results, our product development efforts may be delayed or unsuccessful.

In addition, the use of AI in regulated environments such as biotechnology and pharmaceuticals may attract increasing scrutiny from regulatory authorities. Regulatory bodies have not yet established clear guidelines governing the validation, approval, or oversight of AI-generated insights or AI-supported decision-making. Any failure to comply with future regulatory expectations regarding AI could limit our ability to use such technologies or result in penalties or delays.

We also rely on third-party AI platforms, vendors, and cloud infrastructure. Any errors, outages, security breaches, or failures by such third parties may disrupt our operations or compromise proprietary data. Furthermore, as AI technologies become more widely adopted, we may face increased competition from other biotechnology companies leveraging similar tools.

If we are unable to successfully integrate and manage AI within our business, or if AI fails to deliver the expected benefits, our ability to discover and develop new therapies could be materially adversely affected.
