NOTE 1 — ORGANIZATION AND DESCRIPTION OF BUSINESS, LIQUIDITY, AND RISK FACTORS
OS Therapies Incorporated
(“we,” “us,” “our,” the “Company”) is a Delaware corporation incorporated on
The Company intends to focus on the identification, development, and commercialization of treatments for Osteosarcoma and other related diseases. As of June 30, 2025, there is one ongoing clinical trial for Osteosarcoma therapy.
OS Animal Health Corp – Subsidiary
The Company formed OS Animal Health Corp, a Delaware corporation and wholly owned subsidiary of the Company, on June 25, 2025. The entity is a shell at present and has no assets or liabilities. During the three months ended June 30, 2025, the Company entered into a license agreement with this subsidiary, pursuant to which the Company licensed to this subsidiary the rights to use the HER2 Assets (as defined below).
Liquidity
The Company has prepared its financial statements on a going concern basis, which assumes that the Company will realize its assets and satisfy its liabilities in the normal course of business. However, the Company has incurred net losses since its inception and has negative operating cash flows. These circumstances raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty concerning the Company’s ability to continue as a going concern.
As of June 30, 2025, the Company

The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America, and the Company’s fiscal year end is December 31.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in its financial statements and accompanying notes. On an ongoing basis, management evaluates these estimates and judgments, which are based on historical and anticipated results and trends and on various other assumptions that management believes to be reasonable under the circumstances. By their nature, estimates are subject to an inherent degree of uncertainty and, as such, actual results may differ from management’s estimates.
Cash
Cash consists primarily of
deposits with commercial banks and financial institutions. The Company maintains cash balances at various financial institutions. Both
interest and non-interest-bearing accounts with the same insured depository institution are insured by the Federal Deposit Insurance Corporation

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (cont.)
Impairment of Long-Lived Assets
The Company reviews long-lived
assets for impairment when events or changes in circumstances indicate the carrying value of the assets may not be recoverable. Recoverability
is measured by comparison of the book values of the assets to future net undiscounted cash flows that the assets or the asset groups are
expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which
the book value of the assets exceed their fair value, which is measured based on the estimated discounted future net cash flows arising
from the assets or asset groups.
Deferred Offering Costs
Deferred offering costs consist of capitalized underwriting, legal, accounting and other expenses incurred through the balance sheet date that are directly related to the Company’s initial public offering and that were charged to stockholders’ equity upon the completion of such offering. As of June 30, 2025 and December 31, 2024, the Company did not have any capitalized deferred offering costs. Upon completion of the Company’s initial public offering on August 2, 2024, the deferred offering costs were charged to stockholders’ deficit.
Research and Development Costs
Research and development expenses are charged to operations as incurred. Research and development expenses include, among other things, salaries, costs of outside collaborators and outside services, and supplies.
Revenue Recognition
As of the date of incorporation, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, and all subsequent amendments to the ASU (collectively, “ASC 606”), which (i) creates a single framework for recognizing revenue from contracts with customers that fall within its scope and (ii) revises when it is appropriate to recognize a gain (loss) from the transfer of nonfinancial assets.
Stock-Based Compensation
The Company, in accordance with ASC 718, employs the use of stock-based compensation. The compensation expense related to stock granted to employees and non-employees is measured at the grant date based on the estimated fair value of the award and is recognized on a straight-line basis over the requisite service period. Forfeitures are recognized as a reduction of stock-based compensation expense as they occur. Stock-based compensation expense for an award with a performance condition is recognized when the achievement of such performance condition is determined to be probable. If the outcome of such performance condition is not determined to be probable or is not met, no compensation expense is recognized and any previously recognized compensation expense is reversed.
Short-term Leases
For short-term leases, 12
months or less, we record rent expense. Our only lease currently meets this exemption and has been expensed. We have not renewed the current
lease due to landlord restrictions; the ownership is renovating the premises. We have temporarily moved our primary office to 115 Pullman
Crossing Road, Suite #103, in Grasonville, Maryland 21638. The space is the primary office of our Chief Financial Officer and is being
provided rent free. In May 2024, we signed a month-to-month lease for use of general space with JLabs for $

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (cont.)
Income taxes
The Company accounts for income taxes using the asset-and-liability method in accordance with ASC 740, Income Taxes (“ASC 740”). 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 basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on the deferred tax assets and liabilities of a change in tax rate is recognized in the period that includes the enactment date. A valuation allowance is recorded if it is “more likely than not” that some portion or all of the deferred tax assets will not be realized in future periods.
The Company follows the guidance in ASC Topic 740-10 in assessing uncertain tax positions. The standard applies to all tax positions and clarifies the recognition of tax benefits in the financial statements by providing for a two-step approach of recognition and measurement. The first step involves assessing whether the tax position is more-likely-than-not to be sustained upon examination based upon its technical merits. The second step involves measurement of the amount to be recognized.
Tax positions that meet the
more-likely than-not threshold are measured at the largest amount of tax benefit that is greater than
The Company will recognize interest and penalties related to tax positions in income tax expense. As of June 30, 2025 and December 31, 2024, the Company had no unrecognized uncertain income tax positions.
Basic and Diluted Loss per Share
The Company computes loss per share in accordance with ASC 260, Earnings per Share (“ASC 260”). ASC 260 requires presentation of both basic and diluted earnings per share (“EPS”) on the face of the statements of operations. Basic EPS is computed by dividing the net loss available to common shareholders (numerator) by the weighted average number of common shares outstanding (denominator) during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible notes payable using the if-converted method. Diluted EPS excludes all diluted potential shares if their effect is antidilutive.

Fair Value Measurements
The Company applies ASC 820 Fair Value Measurement (“ASC 820”), which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date.
The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances.
The carrying value of the Company’s cash, accounts payable and accrued expenses are approximate fair value because of the short-term maturity of these financial instruments. The redemption feature of the debt instruments is recorded at fair value (See Note 3).
Warrant liability is recorded
at fair value. Currently, there is not an observable market for this type of derivative. Due to the lack of relevant and market reflective
Level 1 and Level 2 inputs, the Company valued the warrant liability using Level 3 inputs, which require significant judgment and estimates
on behalf of management in developing model assumptions. As of June 30, 2025 and December 31, 2024, the carrying value of the warrant
liability in the aggregate was $
The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below:
Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities.
Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.
Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES (cont.)
Warrant Liability
The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.
The warrants issued in connection with a Securities Purchase Agreements, dated as of December 24, 2024 (the “Purchase Agreement”), are recognized as a derivative liability in accordance with ASC 815. The Company recognizes the warrant instruments as a liability at fair value and adjusts the instruments to fair value at each reporting period. The liability is subject to re-measurement at each balance sheet date until exercised or reclassified, and any change in fair value is recognized in the Company’s consolidated statements of operations. The fair value of the warrants issued in connection with the Purchase Agreement were measured using a Binomial simulation model. The determination of the fair value of the warrant liability may be subject to change as more current information becomes available and accordingly the actual results could differ significantly. The derivative warrant liability is classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.
Recent Accounting Pronouncements
The Company has evaluated all recent accounting pronouncements and believes that none of them will have a material effect on the Company’s financial position, results of operations, or cash flows.

The Company evaluated the Notes in accordance with ASC 480, Distinguishing Liabilities from Equity (“ASC 480”), and determined the Notes are considered share-settled debt and should be recorded as a liability. This conclusion was determined based on the debt providing the holder with a variable number of shares at settlement with an aggregate fair value equal to the debt instrument’s outstanding principal. The general measurement guidance in ASC 480 requires obligations that can be settled in shares with a fixed monetary value at settlement (e.g., share-settled debt) to be carried at fair value unless other accounting guidance specifies another measurement attribute. It has been determined that the appropriate guidance for share-settled debt is ASC 835. As a result, the Notes were recorded at the amortized cost. On August 2, 2024, the Company consummated its initial public offering, and the convertible notes, including accrued interest, converted into shares of the Company’s common stock.

Legal Proceedings
From time to time, the Company may be involved in disputes, including litigation, relating to claims arising out of operations in the normal course of business. Any of these claims could subject the Company to costly legal expenses and, while management generally believes that there will be adequate insurance to cover different liabilities at such time the Company becomes a public company and commences clinical trials, the Company’s future insurance carriers may deny coverage or policy limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any such awards could have a material adverse effect on the results of operations and financial position. Additionally, any such claims, whether or not successful, could damage the Company’s reputation and business. The Company is currently not a party to any legal proceedings, the adverse outcome of which, in management’s opinion, individually or in the aggregate, could have a material adverse effect on the Company’s results of operations or financial position. The Company is currently in arbitration for a claim brought by its former investment advisor. The claim is for underwriter compensation for the Company’s initial public offering in August 2025. The Company believes the claim is meritless as it awaits a formal meeting.

The Preferred Stock has the following rights and privileges:
Voting — Votes together with the common stock on all matters on an as-converted basis. Approval of a majority of the New Preferred Stock voting as a separate class will be required to, among other things: (i) adversely change rights of the New Preferred Stock, (ii) change the authorized number of shares of New Preferred Stock.
Conversion — Each share of New Preferred Stock is convertible into one share of common stock (subject to proportional adjustments for stock splits, stock dividends and the like) at any time at the option of the holder. Conversion ratio will be subject to adjustment on a broad-based, weighted average basis in the event of subsequent issuances at a price less than the original issue price (as adjusted) subject to customary exceptions. The conversion into common stock occurred on February 9, 2024.
Liquidation — One

if greater, the amount that the New Preferred Stock would receive on an as-converted basis) will be paid first on each share of New Preferred
Stock, and the balance of proceeds to be paid to common stock. A merger, reorganization, or similar transaction (including a sale, exclusive
license or other disposition of all or substantially all of the assets of the Company or its subsidiaries) will be treated as a liquidation,
thereby triggering payment of the liquidation preference described above. For the avoidance of doubt, the liquidation preference is intended

NOTE 8 — REDEEMABLE PREFERRED STOCK, MEZZAININE EQUITY AND WARRANT LIABILITY (cont.)
Based on the terms of the Warrants and in accordance with ASC 815, the Warrants are accounted for as a liability due to the variable exercise price subject to adjustment. Currently, there is not an observable market for this type of derivative. Due to the lack of relevant and market reflective Level 1 and Level 2 inputs, the Company valued the Warrant liability using Level 3 inputs, which require significant judgment and estimates on behalf of management in developing model assumptions. The Company determined the value of the Warrant liability using a Binomial Simulation, which takes into consideration the fair market value of the Company’s stock, the variable nature of the exercise price, the estimated exercise period, the volatility of its common stock, and the risk-free interest rate.
The following assumptions
were made as of December 31, 2024 in the model: (1) a variable exercise price with a floor of $
The following assumptions
were made as of April 9, 2025 based on stockholder approval in the model for the aggregate warrants: (1) a fixed exercise price of $
As of June 30, 2025, the carrying
value of the Warrant liability in aggregate was . For the six months ended June 30, 2025, the Company recorded a gain on the change
in fair value of the Warrant Liability in the amount of $
The Series A Preferred Stock
and Warrants were issued in a basket transaction. When two or more instruments are issued in a basket transaction and some instruments
will be remeasured at fair value, the proceeds are first allocated to the instruments recorded at their fair value. Next, the residual
method is used to allocate the proceeds to the instrument(s) that are not remeasured at fair value. In this case, the Warrant is subsequently
measured at fair value, and the Series A Preferred Stock instrument is measured at initial carrying value. The Company will first allocate
the proceeds to the Warrant liability, with the residual allocated to the Series A Preferred Stock liability.

Overview
We are a clinical stage biopharmaceutical company focused on the identification, development and commercialization of treatments for Osteosarcoma (OS) and other solid tumors. Our mission is to address the significant need for new treatments in cancers of the bone in children and young adults. Osteosarcoma is an extremely challenging and often aggressive cancer that has particular treatment challenges due to its location, changing genotypes and high metastases rates. We are currently seeking to answer the call for new treatments that will prevent metastasis and the recurrence of metastases with our lead core product candidate OST-HER2 (also known as OST31-164), a cancer immunotherapy product candidate that produces a cellular immune response against the cancer antigen HER2. In 2021, we opened a clinical study to produce data for the U.S. Food and Drug Administration (FDA) to evaluate the safety and efficacy of OST-HER2 in patients after resection of recurrent Osteosarcoma, which achieved full enrollment of 41 patients in October 2023. In June 2025, we participated in a Type D meeting with the FDA and subsequently received positive written feedback regarding the design and endpoints of our Phase IIb trial of OST-HER2 to support a potential Biologics License Application (BLA). Based on this feedback, we have submitted a Breakthrough Therapy Designation request and, subject to continued positive regulatory guidance, plan to submit a BLA for OST-HER2 following our End of Phase 2 meeting with the FDA, anticipated in the third quarter of 2025. Upon success in gaining regulatory approval from the FDA with OST-HER2 in Osteosarcoma, we intend to evaluate OST-HER2’s potential use, both alone and in combination with HER2 targeting antibodies such as Herceptin®, in other solid tumors including breast, esophageal and lung cancers. OST-HER2 has potential uses in both the prevention of metastases in solid tumors, and therapeutically against HER2-expressing solid tumors treated with HER targeting antibodies.
30
We also own rights to OST-Tunable Drug Conjugate (OST-tADC) platform, a next generation antibody-drug conjugate (ADC) silicone dioxide linker technology. “Tunable” is a term used in drug development that refers to the properties that can be influenced by chemical modifications, and “antibody-drug conjugate” or ADC is a term used to describe a drug made up of a monoclonal antibody attached to a cytotoxic payload, or a highly active and toxic pharmaceutical molecule, through chemical linkers. The ADC links an antibody that can home in on a targeted tumor to deploy the cytotoxic payload or toxic agent against the tumor. Furthering our founding mission, we intend to investigate clinical indications for OST-tADC in Osteosarcoma and other solid tumors.
Recent Developments
PIPE Financing
On December 24, 2024, we entered into a Securities Purchase Agreement (the “PIPE Purchase Agreement”) with certain institutional and accredited investors (collectively, the “Purchasers”), substantially all of whom were existing stockholders of our company, pursuant to which we agreed to issue and sell to the Purchasers immediately separable units (the “Units”), with each Unit being comprised of (i) one share of Series A senior convertible preferred stock (“Series A Preferred Stock”) and (ii) a warrant to purchase one share of common stock (each, a “Series A Warrant” and such shares, the “Warrant Shares”), at a price per Unit of $4.00, for aggregate gross proceeds of not less than $6 million and not more than $10 million (the “PIPE Financing”). At two closings occurring on December 31, 2024 and January 14, 2025, we issued to the PIPE investors an aggregate of (i) 1,775,750 shares of Series A Preferred Stock and (ii) Series A Warrants initially exercisable into 1,775,750 shares of common stock. The gross proceeds from the PIPE Financing, before deducting transaction fees and other estimated PIPE Financing expenses, were approximately $7,103,000.
Brookline Capital Markets, a division of Arcadia Securities, LLC (“Brookline”), acted as exclusive placement agent for the issuance and sale of the securities in the PIPE Financing. We agreed to pay Brookline an aggregate cash fee (the “Cash Fee”) equal to (i) 7% of the gross proceeds received by us from the sale of the securities in the PIPE Financing to Purchasers other than certain Purchasers identified on a schedule thereto (“Reduced Fee Purchasers”) plus (ii) 3% of the gross proceeds received by us from the sale of the securities in the PIPE Financing to Reduced Fee Purchasers, plus expenses; provided that Ceros Financial Services, Inc., Brookline’s selected dealer for the PIPE Financing (“Ceros”), is entitled to up to 33.3% of the Cash Fee.
In addition, we agreed to pay Brookline or its designee a fee in the form of warrants to purchase shares of common stock (the “Agent Warrants”). The Agent Warrants are initially exercisable into a number of shares of common stock equal to (i) 7% of the number of shares of common stock initially issuable pursuant to the shares of Series A Preferred Stock issued to Purchasers other than Reduced Fee Purchasers in the PIPE Financing plus (ii) 3% of the number of shares of common stock initially issuable pursuant to the shares of Series A Preferred Stock issued to the Reduced Fee Purchasers in the PIPE Financing; provided that, Ceros is entitled to up to 33.3% of the Agent Warrants. The terms of the Agent Warrants are substantially similar to the terms of the Series A Warrants. At two closings occurring on December 31, 2024 and January 14, 2025, (i) Brookline received an aggregate cash fee of $159,685 and the right to receive Agent Warrants initially exercisable for an aggregate of 39,918 shares of common stock, and (ii) Ceros received an aggregate cash fee of $79,723 and the right to receive Agent Warrants initially exercisable for an aggregate of 19,930 shares of common stock.
The PIPE Purchase Agreement required us to seek stockholder approval for any transactions contemplated by the PIPE Purchase Agreement and the related documents for which the rules of the NYSE American require stockholder approval (“Stockholder Approval”) and to hold a special meeting of stockholders for the purpose of obtaining Stockholder Approval not later than April 9, 2025.
On April 9, 2025, we convened a Special Meeting of Stockholders (the “Special Meeting”) for the Stockholder Approval, in accordance with NYSE American LLC Company Guide Section 713(a), of the issuance of shares of our common stock upon (i) the conversion of 1,775,750 shares of Series A Preferred Stock, (ii) the exercise of the Series A Warrants, and (iii) the exercise of the Agent Warrants in connection with our PIPE Financing, in each case without regard to any limits on conversion or exercise therein and in amounts collectively equal to or exceeding 20% of our common stock outstanding as of December 24, 2024 (including upon the operation of applicable price reset and anti-dilution provisions and/or the reduction of conversion prices and exercise prices) (the “Issuance Proposal”). The Issuance Proposal was approved by the affirmative vote of a majority of the votes cast by our stockholders at the Special Meeting.
Our Acquisition of HER2 and Lm-Related Assets
On April 9, 2025, pursuant to the terms of an Asset Purchase Agreement, dated as of January 28, 2025 (the “HER2 Purchase Agreement”), between us and Ayala Pharmaceuticals, Inc., a Delaware corporation formerly known as Advaxis, Inc. (“Ayala”), we completed the acquisition of the Lm-based immune-oncology programs and related intellectual property assets (the “HER2 Assets”) from Ayala. The HER2 Assets include two investigational new drug (IND) filings with the FDA: (i) ADXS-503 for non-small cell lung cancer; and (ii) ADXS-504 for prostate cancer.
31
In consideration for the purchase of the HER2 Assets, we agreed to assume certain specified liabilities and to pay an aggregate purchase price of $8,000,000, which was paid as follows: (i) $400,000 to Ayala ($150,000 of which was transferred upon signing of the HER2 Purchase Agreement and the remainder on the closing date); (ii) $100,000 to a third party on behalf of Ayala on the closing date; and (iii) $7,500,000 worth of shares of our common stock, or 4,774,637 shares based on the volume-weighted average price of the Company’s common stock over the 30 trading days immediately preceding the closing date (the “Ayala Consideration Shares”).
Because the issuance of the Ayala Consideration Shares would have required us to issue more than 19.99% of our outstanding common stock immediately prior to such issuance (the “NYSE Ownership Limitation”), we issued to Ayala (i) 2,164,215 shares of common stock, and (ii) a warrant to purchase 2,166,381 shares of common stock (the “Ayala Warrant” and the shares of common stock issuable thereunder, the “Ayala Warrant Shares”). Once we obtain stockholder approval in accordance with NYSE American LLC Company Guide Section 713, we will subsequently issue to Ayala the remaining 444,041 shares of common stock (the “Ayala Additional Consideration Shares”), except that, if at that time, the number of shares of common stock beneficially owned by Ayala would exceed 9.99% of the number of shares of our common stock then outstanding, Ayala has the right to require us to issue, in lieu of such shares, a warrant to purchase 444,041 on substantially the same terms of the Ayala Warrant.
Ayala entered into a lock-up agreement, pursuant to which, and subject to the terms and conditions set forth therein, Ayala has agreed not to trade or transfer, subject to certain customary exceptions, any of the Ayala Consideration Shares (including the Ayala Warrant Shares) for a period of 180 days following the closing of the transaction.
Warrant Exercise Inducement and Exchange Offer
On July 11, 2025, we completed a final closing of a warrant exercise inducement and exchange offer (the “Offering”). The Offering was made to holders (the “Holders”) of certain of our existing warrants to purchase shares of our common stock, having a then current exercise price of $1.12 per share, originally issued to the Holders pursuant to the PIPE Purchase Agreement (the “Existing Warrants”), during the period beginning on June 20, 2025 and ending at 5:00 p.m., Eastern time, on July 10, 2025 (the “Inducement Period”).
During the Inducement Period, we entered into inducement offer letter agreements (the “Inducement Letters”) with the Holders of Existing Warrants, pursuant to which the Holders agreed to exercise for cash their Existing Warrants to purchase an aggregate of 3,764,995 shares of our common stock in consideration of our agreement to issue new warrants (the “New Warrants”) to purchase up to an aggregate of 3,764,995 shares of our common stock (the “New Warrant Shares”) at an exercise price of $3.00 per share, subject to adjustment as provided therein. The New Warrants are immediately exercisable from the date of issuance and have a term of exercise of five years from such date.
We engaged an SEC registered broker dealer and FINRA member (the “Solicitation Agent”) to act as our exclusive warrant solicitation agent in connection with the Offering and agreed to pay the Solicitation Agent a cash fee equal to 5.0% of the total gross cash proceeds received from the exercise by the Holders of their Existing Warrants during the Inducement Period. We also agreed to pay the Solicitation Agent up to $15,000 for its reasonable legal and other expenses.
The gross proceeds to us from the Offering, before deducting transaction fees and other estimated Offering expenses, were approximately $4,216,794. We intend to use the net proceeds to support U.S. and international regulatory and pre-commercial efforts aimed at securing marketing authorizations for OST-HER2 in the prevention or delay of recurrent, fully resected, pulmonary metastatic osteosarcoma, advance strategic alternatives for our OS Animal Health subsidiary, close out and report on our OST-504 (previously ADXS-504) prostate cancer study, initiate AI-driven next-generation tADC product candidate modeling and for general corporate purposes.
We also agreed to file a registration statement on Form S-3 (or other appropriate form, including on Form S-1, if we are not then eligible to register securities on Form S-3) (the “Resale Registration Statement”) providing for the resale of the shares of common stock issued or issuable upon exercise of the New Warrants, within 30 calendar days of the final closing, and to use commercially reasonable efforts to have such Resale Registration Statement declared effective by the SEC within 60 calendar days (or within 90 calendar days in case of “full review” of the Resale Registration Statement by the SEC) following the initial filing of such Resale Registration Statement and to keep the Resale Registration Statement effective at all times until the earlier of (i) the time no holder of the New Warrants owns any New Warrants or New Warrant Shares and (ii) the Delegend Date (as defined in the Inducement Letters).
Critical Accounting Policies and Estimates
Our financial statements are prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The preparation of our financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.
32
Critical accounting policies are those that, in management’s view, are most important to the portrayal of a company’s financial condition and results of operations and most demanding on their calls on judgment, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. While our significant accounting policies are described in more detail in Note 2 to our financial statements appearing elsewhere in this annual report, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.
Warrant Liability
We do not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. We evaluate all of our financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.
The Series A Warrants issued in connection with the Purchase Agreement are recognized as a derivative liability in accordance with ASC 815. We recognize the warrant instruments as a liability at fair value and adjust the instruments to fair value at each reporting period. The liability is subject to re-measurement at each balance sheet date until exercised or reclassified, and any change in fair value is recognized in our consolidated statements of operations. The fair value of the Series A Warrants was measured using a Binomial simulation model. The determination of the fair value of the warrant liability may be subject to change as more current information becomes available, and accordingly, the actual results could differ significantly. The derivative warrant liability is classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.
Components of Our Results of Operations
Revenue. We did not recognize revenues for the six months ended June 30, 2025 and 2024.
Operating Expenses. Our operating expenses are comprised primarily of research and development expenses, general and administrative expenses and licensing costs.
Research and Development Expenses. Research and development expenses consist primarily of costs incurred for our research activities, including our drug discovery efforts, and the development of our product candidates, which include:
| ● | personnel-related costs, including salaries, benefits and stock-based compensation expense, for employees engaged in research and development functions; |
| ● | expenses incurred in connection with our research programs, including under agreements with third parties, such as consultants and contractors and CROs; |
33
| ● | the cost of developing and scaling our manufacturing process and manufacturing drug substance and drug product for use in our research and preclinical and clinical studies, including under agreements with third parties, such as consultants and contractors and contract development and manufacturing organizations (CDMOs); and |
| ● | the cost of laboratory supplies and research materials. |
We track our direct external research and development expenses on a program-by-program basis. These consist of costs that include fees, reimbursed materials, and other costs paid to consultants, contractors, CDMOs, and CROs in connection with our preclinical, clinical and manufacturing activities. We do not allocate employee costs, costs associated with our discovery efforts, and facilities expenses, including depreciation or other indirect costs, to specific product development programs because these costs are deployed across multiple programs and, as such, are not separately classified.
We expect that our research and development expenses will increase substantially as we advance OST-HER2 and OST-tADC into clinical development and expand our discovery, research and preclinical activities.
General and Administrative Expenses. General and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, for personnel in executive, finance and administrative functions. General and administrative expenses also include professional fees for legal, consulting, investor and public relations and accounting and audit services.
We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research activities and development of our product candidates. We also anticipate that we will incur increased accounting, audit, legal, regulatory, compliance, and director and officer insurance costs as well as investor and public relations expenses associated with operating as a public company.
Licensing Costs. Costs incurred in obtaining technology licenses and asset purchases are charged to licensing costs if the technology licensed has not reached technological feasibility which includes manufacturing, clinical, intellectual property and/or regulatory success which has no alternative future use. The licenses purchased by us require substantial completion of research and development and regulatory and marketing approval efforts in order to reach technological feasibility.
Interest Expense. We evaluated the convertible notes issued by us from July 2018 to April 2024 in accordance with ASC 480, Distinguishing Liabilities from Equity (“ASC 480”), and determined the convertible notes are considered share-settled debt and should be recorded as a liability. This conclusion was determined based on the debt providing the holder with a variable number of shares at settlement with an aggregate fair value equal to the debt instrument’s outstanding principal. The general measurement guidance in ASC 480 requires obligations that can be settled in shares with a fixed monetary value at settlement (e.g., share-settled debt) to be carried at fair value unless other accounting guidance specifies another measurement attribute. It has been determined that the appropriate guidance for share-settled debt is ASC 835. As a result, the convertible notes were recorded at the amortized cost.
Cumulative Series A Preferred Stock Dividend. The Series A preferred stock dividend requirement represents the coupon dividends on our preferred stock that has since been converted and is identified as a separate component of our statement of operations to compute net income (loss) available to common stockholders. The coupon dividends are computed at 5% of the principal per annum and are recorded monthly. The cumulative accrued dividend as of June 30, 2025 and December 31, 2024 were $375,000 and $375,000, respectively. The Series A preferred stock was converted into common stock on a 1:1 basis in February 2024, and the last coupon dividend was issued in the quarter ended March 31, 2024.
Income Taxes. Since our inception, we have not recorded income tax benefits for the net operating losses incurred or the research and development tax credits generated in each year, due to the uncertainty of realizing a benefit from those items.
For years ended December 31, 2024 and December 31, 2023, we had federal net operating loss (“NOLs”) of $22,236,580 and $16,269,893, respectively. The 2019 NOL carryforward of $292,144 will expire in tax years up through 2037. The NOLs generated in tax years 2020 and beyond will carry forward indefinitely, but the deductibility of such federal NOLs is limited. We have provided a valuation allowance to offset the deferred tax assets due to the uncertainty of realizing the benefits of the net deferred tax asset.
Our issuances of common stock have resulted in ownership changes as defined by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”); however, we have not conducted a Section 382 study to date. It is likely that a future analysis may result in the conclusion that a substantial portion, or perhaps substantially all, of our NOL carryforwards and R&D tax credit carryforwards will expire due to the limitations of Sections 382 and 383 of the Code. As a result, the utilization of the carryforwards may be limited, and a portion of the carryforwards may expire unused. We are subject to U.S. federal tax examinations by tax authorities for the year 2021 due to the fact that NOL carryforwards exist going back to 2019 that may be utilized on a current or future year tax return.
Deferred Offering Costs. Deferred offering costs consisted of legal, accounting, printing and filing fees that we capitalized, which were offset against the gross proceeds from our initial public offering.

Research and Development Expenses. Research and development expenses were approximately $3.8 million for the six months ended June 30, 2025 compared to approximately $0.8 million for the six months ended June 30, 2024. This increase was primarily due to an increase in vendor expenses associated with our Phase IIb clinical trial, as we compile data to submit to various governmental agencies, and a decrease in vendor expenses associated with out OST-tADC platform technology.
Research and development expenses were approximately $2.5 million for the three months ended June 30, 2025 compared to approximately $0.4 million for the three months ended June 30, 2024.

For the six months ended June 30, 2025 and 2024, the direct research and development expenses related to OST-HER2 were primarily lab fees, vendor expenses and staff payroll fees. In 2025, such expenses were primarily lab fees and related clinical support of approximately $1.0 million attributed to our Phase IIb clinical trial preparation, advisor fees of $1.9 million, and legal costs of $0.1 million as we completed IND-enabling studies. OST-tADC related direct research and development expenses were approximately $0.0 million and $0.0 million for the six months ended June 30, 2025 and 2024, respectively.
For the three months ended June 30, 2025 and 2024, the direct research and development expenses related to OST-HER2 were primarily lab fees, vendor expenses and staff payroll fees. In 2025, such expenses were primarily lab fees and related clinical support of approximately $0.6 million attributed to our Phase IIb clinical trial preparation, and advisor fees of $1.4 million, as we completed IND-enabling studies. OST-tADC related direct research and development expenses were approximately $0.0 million and $0.0 million for the three months ended June 30, 2025 and 2024, respectively.
General and Administrative Expenses. General and administrative expenses for the six months ended June 30, 2025 were approximately $6.0 million compared to $0.7 million for the six months ended June 30, 2024. These expenses were primarily attributed to marketing and investor relations costs and advisory fees associated with the PIPE Financing and equity line of credit.
General and administrative expenses for the three months ended June 30, 2025 were approximately $2.3 million compared to $0.4 million for the three months ended June 30, 2024. These expenses were primarily attributed to marketing and investor relations costs and advisory fees associated with the PIPE Financing and equity line of credit.
35
Interest Expense. Interest expense for the six months ended June 30, 2025 was approximately $0.0 million compared to $1.6 million for the six months ended June 30, 2024.
Interest expense for the three months ended June 30, 2025 was approximately $0.0 million compared to $0.8 million for the three months ended June 30, 2024.
Change in Fair Value of Warrant
The Series A preferred stock coupon dividend requirement of $31,250 for the six months ended June 30, 2024 represents an expense that terminated during the period ended March 31, 2024 upon the conversion of our old Series A preferred shares into shares of our common stock. We issued Series A convertible preferred stock and detachable warrants on December 31, 2024 and January 14, 2025. The adjustment of the fair value of the warrant liability was $1.4 million and $0.0 million for the six months ended June 30, 2025 and 2024, respectively.
Liquidity and Capital Resources
Operating Losses
Since our inception, we have incurred significant operating losses. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of our product candidates. For the six months ended June 30, 2025 and 2024, we reported a net loss of approximately $8.4 million and $3.0 million, respectively, and had an accumulated deficit of approximately $47 million and $33 million, respectively. We expect to incur significant expenses at an increasing rate and increasing operating losses for the foreseeable future. For the three months ended June 30, 2025 and 2024, we reported a net loss of approximately $4.5 million and $1.6 million, respectively.
As of June 30, 2025 and December 31, 2024, we had cash of approximately $2.8 million and $5.5 million, respectively. We have funded our operations to date primarily from the sale of our convertible notes and Series A securities in our private placements and cash exercises of our warrants, as well as the sale of our common stock in our initial public offering, which have provided total gross proceeds of $37.1 million as of June 30, 2025. We believe that the net proceeds from our private placements and initial public offering, together with our existing cash, will enable us to fund our operating expenses and capital expenditure requirements for the next nine to 12 months.
Cash Flows
The following table summarizes our sources and uses of cash for the six months ended June 30, 2025 and 2024:
| June 30, | ||||||||
| (In thousands) | 2025 | 2024 | ||||||
| Cash used in operating activities | $ | (5,869 | ) | $ | (1,523 | ) | ||
| Cash used in investing activities | (400 | ) | - | |||||
| Cash provided by financing activities | 3,537 | 1,579 | ||||||
| Net increase (decrease) in cash | $ | (2,732 | ) | $ | 56 | |||
Operating Activities
During the six months ended June 30, 2025 and 2024, operating activities used approximately $5.9 million and $1.5 million of cash, respectively, resulting from our net loss of approximately $8.4 million and $3.0 million, respectively, offset by net non-cash charges of approximately $1.4 million and $1.1 million, respectively, partially offset by net cash provided by changes in our operating assets and liabilities of approximately $1.2 million and $0.4 million, respectively.
Net cash provided by changes in our operating assets and liabilities for the six months ended June 30, 2025 and 2024 consisted primarily of an increase (decrease) in accounts payable of approximately $1.1 million and $(0.05) million, respectively, an increase in accrued interest of approximately $0.0 million and $0.5 million, respectively, and a change in prepaid expenses of approximately $0.4 million and $(0.0) million, respectively. The change in accrued expenses of approximately $(0.15) million and $0.3 million was a portion of the use.
36
Non-cash charges for the six months ended June 30, 2025 and 2024 were primarily the result of the changes in the fair value of our warrant liability of $(1.4) million and $0.0 million, respectively, combined with our common stock shares issued for service and our stock-based compensation of approximately $2.7 million and $0.0 million, respectively. Changes in accounts payable, accrued expenses and other current liabilities and prepaid expenses and other current assets in all periods were generally due to growth in our business, the advancement of our research programs and the timing of vendor invoicing and payments.
Investing Activities
During the six months ended June 30, 2025 and 2024, net cash used in investing activities was approximately $0.4 million and $0.0 million, respectively.
Financing Activities
For the six months ended June 30, 2025 and 2024, net cash provided by financing activities was approximately $3.5 million and $1.6 million, respectively. For the six months ended June 30, 2025, we saw funds raised from our Series A securities offering of $1.1 million and our warrant inducement exercise offering of $2.5 million.
Convertible Notes. We completed seven separate private financing transactions from July 2018 to April 2024 in which we issued convertible notes and raised total gross proceeds of $19,426,449 from accredited investors. All of the convertible notes were automatically converted into shares of our common stock at the closing of our initial public offering.
Demand Notes. On March 6, 2024 and June 28, 2024, we issued demand promissory notes to a lender who was an investor in one of our prior convertible notes rounds in a principal amount of $100,000 and $150,000, respectively. The demand notes bear interest at a rate of 8% per annum and the principal plus all accrued interest is payable upon demand by such lender. If such notes are not paid on demand by us, interest will accrue at a rate of the lesser of 16% per annum and the highest rate of interest allowable under Maryland law.
As of August 14, 2024, we repaid the demand notes in full.
BlinkBio. On August 19, 2020, we issued a convertible note with a principal amount of $2,400,000 (the “BlinkBio Convertible Note”) to BlinkBio, Inc., which was a related party because our former Chairman, Colin Goddard, Ph.D., is the Chairman and Chief Executive Officer of BlinkBio, in exchange for the entry into the license agreement. On March 15, 2021, the principal and unpaid accrued interest of $100,000 of the BlinkBio Convertible Note converted into 1,302,082 shares of our Series A preferred stock and then distributed to BlinkBio stockholders. The BlinkBio Convertible Note had a conversion capitalization ceiling of $19.2 million, which limited the price a noteholder must pay in a convertible note-to-common stock conversion occurrence. On February 9, 2024, the 1,302,082 shares of our Series A preferred stock were converted into 651,041 shares of common stock (on a post-split basis).
TEDCO Grant. In May 2021, we received the first of two tranches from TEDCO’s Rural & Underserved Business Recovery from Impact of Covid-19 (RUBRIC) Grant in the amount of $50,000. In October 2021, we received the second tranche of $50,000, which brought the total reimbursable grant amount to $100,000. We are obligated to report on and pay to TEDCO 3% of their quarterly revenues for a five-year period following the reward date. Income from grants and investments are not considered revenues. Royalties due to TEDCO are capped at 150% of the amount of the award, or $150,000. We have the option to eliminate the quarterly royalty obligation by making an advance payment prior to the end of the five-year period, in which case, we will receive a 10% reduction of the royalty cap percentage for each year prior to the expiration of the five-year reimbursement period that the grant is repaid in full. If we cease to meet eligibility requirements at any time, the reimbursement obligation will become due to TEDCO immediately; however, the discount for meeting the obligation will still apply.
37
PIPE Financing
On December 24, 2024, we entered into the PIPE Purchase Agreement with the selling stockholders, substantially all of whom were existing stockholders of the Company, pursuant to which we agreed to issue and sell to the selling stockholders the Units for aggregate gross proceeds of not less than $6 million and not more than $10 million. At two closings occurring on December 31, 2024 and January 14, 2025, we issued to the selling stockholders an aggregate of (i) 1,775,750 shares of Series A Preferred Stock and (ii) Series A Warrants initially exercisable into 1,775,750 shares of common stock. The gross proceeds from the closing of the PIPE Financing, before deducting transaction fees and other estimated PIPE Financing expenses, were approximately $7,103,000. The Purchase Agreement requires us to seek stockholder approval for any transactions contemplated by the Purchase Agreement and the related documents for which the rules of the NYSE American require stockholder approval (“Stockholder Approval”) and to hold a special meeting of stockholders for the purpose of obtaining Stockholder Approval not later than April 10, 2025. In the event Stockholder Approval is not obtained at the first meeting, we are required to call a meeting every four months seeking Stockholder Approval until Stockholder Approval is obtained.
On April 9, 2025, we convened the Special Meeting for the Stockholder Approval, in accordance with NYSE American LLC Company Guide Section 713(a), of the issuance of shares of our common stock upon (i) the conversion of 1,775,750 shares of Series A Preferred Stock, (ii) the exercise of the Series A Warrants, and (iii) the exercise of the Agent Warrants in connection with our PIPE Financing, in each case without regard to any limits on conversion or exercise therein and in amounts collectively equal to or exceeding 20% of our common stock outstanding as of December 24, 2024 (including upon the operation of applicable price reset and anti-dilution provisions and/or the reduction of conversion prices and exercise prices). The Issuance Proposal was approved by the affirmative vote of a majority of the votes cast by our stockholders at the Special Meeting.
Brookline acted as exclusive placement agent for the issuance and sale of the securities in the PIPE Financing. Pursuant to the terms of the Placement Agency Agreement, we agreed to pay Brookline an aggregate cash fee (the “Cash Fee”) equal to (i) 7% of the gross proceeds received by the Company from the sale of the securities in the PIPE Financing to selling stockholders other than certain selling stockholders identified on a schedule thereto (“Reduced Fee Purchasers”) plus (ii) 3% of the gross proceeds received by the Company from the sale of the securities in the PIPE Financing to Reduced Fee Purchasers, plus expenses; provided that Ceros is entitled to 33.3% of the Cash Fee.
In addition, we agreed to pay Brookline or its designees a fee in the form of the Agent Warrants. The Agent Warrants are initially exercisable into a number of shares of common stock equal to (i) 7% of the number of shares of common stock initially issuable pursuant to the shares of Series A Preferred Stock issued to Purchasers other than Reduced Fee Purchasers in the PIPE Financing plus (ii) 3% of the number of shares of common stock initially issuable pursuant to the shares of Series A Preferred Stock issued Reduced Fee Purchasers in the PIPE Financing; provided that, Ceros is entitled to up to 33.3% of the Agent Warrants. The terms of the Agent Warrants are substantially similar to the terms of the Series A Warrants. At two closings occurring on December 31, 2024 and January 14, 2025, (i) Brookline received an aggregate cash fee of $159,685 and 39,918 Agent Warrants, and (ii) Ceros received an aggregate cash fee of $79,723 and 19,930 Agent Warrants.
Warrant Exercise Inducement and Exchange Offer
On July 11, 2025, we completed the final closing of the Offering. During the Inducement Period, we entered into Inducement Letters with the Holders of Existing Warrants, pursuant to which the Holders agreed to exercise for cash their Existing Warrants to purchase an aggregate of 3,764,995 shares of our common stock in consideration of our agreement to issue New Warrants to purchase up to an aggregate of 3,764,995 shares of our common stock at an exercise price of $3.00 per share, subject to adjustment as provided therein. The New Warrants are immediately exercisable from the date of issuance and have a term of exercise of five years from such date.
We engaged an SEC registered broker dealer and FINRA member (the “Solicitation Agent”) to act as our exclusive warrant solicitation agent in connection with the Offering and agreed to pay the Solicitation Agent a cash fee equal to 5.0% of the total gross cash proceeds received from the exercise by the Holders of their Existing Warrants during the Inducement Period. We also agreed to pay the Solicitation Agent up to $15,000 for its reasonable legal and other expenses.
The gross proceeds to us from the Offering, before deducting transaction fees and other estimated Offering expenses, were approximately $4,216,794. We intend to use the net proceeds to support U.S. and international regulatory and pre-commercial efforts aimed at securing marketing authorizations for OST-HER2 in the prevention or delay of recurrent, fully resected, pulmonary metastatic osteosarcoma, advance strategic alternatives for our OS Animal Health subsidiary, close out and report on our OST-504 (previously ADXS-504) prostate cancer study, initiate AI-driven next-generation tADC product candidate modeling and for general corporate purposes.
38
Contractual Obligations and Other Commitments
We enter into contracts in the normal course of business with our CDMOs, CROs and other third parties to support preclinical research studies and testing and other development activities. These contracts are generally cancellable by us. Payments due upon cancellation consist only of payments for services provided or expenses incurred, including non-cancellable obligations of our service providers, up to the date of cancellation.
License Obligations and Research Services
Advaxis. In November 2020, we entered into an amended and restated development, license and supply agreement with Advaxis, Inc. (now Ayala Pharmaceuticals, Inc.) (“Advaxis”), a clinical-stage biotechnology company focused on the development and commercialization of proprietary Lm (Listeria monocytogenes)-LLO (Listeriolysin O) cancer immunotherapies. Pursuant to this agreement, Advaxis granted a license to us that allows us to utilize Advaxis’ ADXS-HER2 construct patents to develop and commercialize ADXS-HER2, our lead product candidate (OST-HER2). The agreement was subsequently amended in April 2021 to modify the payment amounts for Milestones 2 and 3 listed in the table below. Under the terms of the amended agreement, we are required to pay to Advaxis (i) a one-time, non-refundable payment of $1,550,000 (the “License Commencement Payment”) and (ii) certain amounts based on the achievement of the milestones described in the payment schedule below. For the six months ended June 30, 2025 and for the year ended December 31, 2024, no payments were made. A $400,000 payment was made to Ayala, together with payment of stock consideration, in connection with our purchase of the HER2 Assets on April 9, 2025, terminating this license agreement. The payment schedule for milestones and corresponding payment amounts were as set forth below.

On April 9, 2025, we acquired from Ayala the HER2 Assets. Pursuant to the terms of the HER2 Purchase Agreement, the amended and restated development, license and supply agreement with Advaxis terminated, and we agreed to a change in milestone payments and royalty consideration owed as it relates to the OST-HER2 program as follows:
| 1. | Elimination of $3,500,000 payment owed to Ayala upon the first filing of a BLA approval for OST-HER2 with the FDA. |

In addition, we have agreed to pay an annual fee to the Trustees of the University of Pennsylvania. In April 2025, the Company paid a fee of $266,317 for the six months ended June 30, 2025 for the period from April 9, 2025 through April 8, 2026.
BlinkBio. In August 2020, we entered into a licensing agreement with BlinkBio, Inc., a privately-held developer of drug conjugate therapies designed to facilitate the treatment of cancer. Pursuant to this agreement, BlinkBio granted a license to us that allows us to utilize BlinkBio’s proprietary technology to develop, manufacture and commercialize certain of our products. BlinkBio granted us an exclusive license for tunable drug conjugates that are directed towards, binds to or modifies the folate receptor alpha and a co-exclusive license for tunable drug conjugates that are directed towards, binds to or modifies any target other than the folate receptor alpha, such as HER2.
Under the terms of the agreement, we are required to pay to BlinkBio (i) an upfront, non-refundable, non-creditable license fee of $300,000 (the “Up-Front Fee”), (ii) a royalty of 6% of net sales of our products that were made using BlinkBio’s proprietary technology, subject to potential reductions on such royalty, and (iii) certain amounts based on the achievement of the milestones described in the payment schedule below.
40
As of June 30, 2025, we had paid the Up-Front Fee. The payment schedule for milestones and corresponding payment amounts is set forth below.

We are required to make the above cash payments to BlinkBio within 30 days of the achievement of each milestone with respect to the first product to attain each such milestone, except that the first milestone only applies to our first product candidate. The aggregate amount of payments relating to milestones 2 through 6 payable thereunder cannot exceed $22,375,000.
In connection with the license agreement, we also agreed to issue the BlinkBio Convertible Note. See “— Convertible Notes” above for more information on the BlinkBio Convertible Note.
George Clinical. In June 2020, we entered into a services agreement, as amended, with George Clinical, Inc., a clinical contract research organization. Pursuant to this agreement, we engaged George Clinical to use its clinical research services for our study entitled “An Open Label, Phase 2 Study of Maintenance Therapy with OST-HER2 after Resection of Recurrent Osteosarcoma.” Under the terms of the agreement, we are required to pay to George Clinical certain fees described in the fee schedule below. The total new budget under the agreement is approximately $2,436,928. For the six months ended June 30, 2025 and 2024, we paid $0 and $86,687, respectively, to George Clinical. These payments have been recorded as research and development expenses in our Statement of Operations and Comprehensive Loss. The fee schedule for certain fees and corresponding payment amounts is set forth below.

Off-Balance Sheet Arrangements
We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.
Recent Accounting Pronouncements
A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2 to Notes to the Financial Statements appearing elsewhere in this report.
The JOBS Act
The JOBS Act permits an emerging growth company such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We have elected to avail ourselves of the extended transition period for complying with new or revised financial accounting standards.
We will remain an emerging growth company until the earliest of (i) the last day of our first fiscal year in which we have total annual gross revenues of $1.235 billion or more; (ii) the date on which we are deemed to be a “large accelerated filer” under the rules of the SEC with at least $700.0 million of outstanding equity securities held by non-affiliates; (iii) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the previous three years; or (iv) the last day of our fiscal year following the fifth anniversary of the date of the completion of our initial public offering.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Not applicable.
Item 4. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) are controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Due to the inherent limitations of control systems, not all misstatements may be detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. Controls and procedures can only provide reasonable, not absolute, assurance that the above objectives have been met.
Our management, including our Chief Executive Officer and Chief Financial Officer, has conducted an evaluation of the effectiveness of disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded as of June 30, 2025, that the disclosure controls and procedures are not effective due to lack of segregation of duties as a result of limited personnel and insufficient written policies and procedures for accounting, information technology and financial reporting.
There have been no changes in our internal control over financial reporting during the three months ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings.
We are not currently a party to any pending or threatened legal proceedings.
See also Note 6 to our financial statements contained in Item 1 of Part I of this Quarterly Report on Form 10-Q, which is incorporated herein by reference.
Item 1A. Risk Factors.
You should carefully consider the factors discussed under the section entitled “Risk Factors” in our most recent Annual Report on Form 10-K filed with the SEC on March 31, 2025, as such factors could materially affect our business, financial condition, and future results. The risks described in such annual report are not the only risks that we face. Additional risks and uncertainties not currently known to us, or that we currently deem to be immaterial, also may have a material adverse impact on our business, financial condition, or results of operations. There have been no material changes to the risk factors identified in our most recent Annual Report on Form 10-K, other than as set forth below.
The issuance of shares in connection with the Offering and the resale of a significant number of shares by the selling stockholders, or the perception that such sales may occur, could adversely affect the market price of our common stock.
During the Inducement Period, we issued to the Holders New Warrants exercisable for an aggregate of 3,764,995 shares of common stock in exchange for the cash exercise of their Existing Warrants for an equal number of shares, pursuant to the Inducement Letters. In the future, we may issue additional shares of common stock or other securities convertible into or exercisable for common stock. These issuances and any future issuance could result in substantial dilution to our existing stockholders and negatively affect the market price of our common stock.
In addition, sales by the Holders of a significant number of shares of common stock, or the perception that such sales could occur, could materially adversely affect the trading price of our common stock. Even if the Holders do not sell their shares immediately, the registration of such shares for resale could increase market uncertainty and put downward pressure on our stock price. We cannot predict the effect, if any, that future sales or the availability of shares for sale will have on the trading price of our common stock.
