OS Therapies Inc

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 June 24, 2019. It is based in Rockville, Maryland. The Company is the successor to an LLC formed in 2018.

The Company intends to focus on the identification, development, and commercialization of treatments for Osteosarcoma and other related diseases. As of December 31, 2024, there is one ongoing clinical trial for Osteosarcoma therapy.

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 December 31, 2024, the Company had cash of $5,533,527. For the foreseeable future, the Company’s ability to continue its operations is dependent upon its ability to obtain additional capital. The Company is currently seeking to raise additional capital through a public or private financing of equity; although there can be no assurances the Company will be successful in such a campaign.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of U.S. Securities and Exchange Commission (“SEC”). 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 (FDIC) for a combined total of $250,000. In the normal course of business, the Company may have deposits that exceed the FDIC insured limit. The Company believes that it is not subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. As of December 31, 2024, and December 31, 2023, Chase Bank Checking account had $5,216,354 and $88, respectively. Chase Savings account had $20,000 and $0 as of December 31, 2024 and December 31, 2023, respectively. As of December 31, 2024 and December 31, 2023, SVB Bank Checking account had $287,173 and $28,893, respectively, and the SVB Money Market account had $10,000 and $10,000, respectively. The accounts in excess of the FDIC limits are the Chase checking account and the SVB Bank Checking account.

Redeemable Preferred Stock and Mezzanine Equity

The Company’s Series A Preferred Stock, in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 (“ASC 480”), is accounted for as mezzanine equity due to the redemption feature upon a deemed liquidation event: (i) a merger or consolidation, or (ii) the sale, lease, transfer or other disposition of substantially all the assets of the Company. The initial cash proceeds of $6,050,000 were allocated to the Warrants and the residual proceeds were allocated to the Series A Preferred Stock. Because the Series A Preferred Stock is classified as a mezzanine equity, the Company will record a deemed dividend for the accretion of the Series A Preferred Stock to carrying value in accordance with ASC 480.

Fixed Asset Policy

A capital asset is defined as a unit of property that has an economic useful life that extends beyond 12 months. Any items costing below the threshold or not fitting the definition of a capital asset will be expensed in the financial statements. All capital assets are recorded at historical cost as of the date acquired. Computer assets will be capitalized and Straight-Line depreciated over five years for financial statement purposes.

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. No impairment losses on long-lived assets have been recorded for the year ended December 31, 2024 or the year ended December 31, 2023.

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. On December 31, 2024, the Company had$0 in capitalized deferred offering costs. On December 31, 2023, the Company had $751,050 in 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.

Debt Discount and Redemption Premium

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 will be recorded at the amortized cost.

The initial fair value of the redemption value relating to the convertible debt instruments are capitalized and amortized over the term of the related debt using the straight-line method, which approximates the interest method. If a loan is paid in full, any unamortized financing costs will be removed from the related accounts and charged to operations. Amortization of debt discount is recorded as a component of interest expense. In accordance with ASU 2015-03, Interest — Imputation of Interest, the unamortized debt discount is presented in the accompanying balance sheet as a direct deduction from the carrying amount of the related debt.

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 with JLabs for $750 per month, primarily to have meetings in New York City and to have an office for our staff when they are in town.

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 50% likely of being realized upon ultimate finalization with the taxing authority. The Company recognizes the impact of an uncertain income tax position in the financial statements if it believes that the position is more likely than not to be sustained by the relevant taxing authority.

The Company will recognize interest and penalties related to tax positions in income tax expense. As of December 31, 2024 and December 31, 2023, 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.

Below is a table listing all preferred stock and common stock equivalents:

The shares of Series A Convertible Preferred Stock issued on December 31, 2024 are not included in the above table as stockholder approval is required for the issuance of shares of common stock upon any conversion thereof. As of December 31, 2024, the maximum number of shares of common stock to be issued upon conversion of all of the 1,512,500 Series A Convertible Preferred Stock is 6,050,000 shares of common stock.

Fair Value Measurements

The Company applies ASC 820Fair 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 December 31, 2024, the carrying value of the warrant liability in the aggregate was $1,971,975 (See Note 9).

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.

*** 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 Agreement, 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.

Accounting Principles Adopted

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, requiring public companies to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. Public companies with a single report segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements of ASU 2023-07 during the year ended December 31, 2024. The Company operates as one operating segment and the Company’s CEO is the chief operating decision maker (“CODM”). The CODM uses the consolidated statement of operations to assess financial performance and allocate resources.

NOTE 3 — RELATED PARTY TRANSACTIONS

Accrued Payroll

NOTE 4 — CONVERTIBLE DEBT

Convertible Debt

The Company’s convertible notes are separated into seven groups — A, B, C, D, E, F and BlinkBio — per the table below:

The above convertible notes were all converted into common stock on August 2, 2024 upon consummation of the Company’s initial public offering.

Group A

Commencing in July 2018 through November 2021, the Company entered into an unsecured Subordinated Convertible Promissory Note Agreement (the “Agreements”) with certain lenders (together, the “Holders” or individually, the “Holder”). Interest on the unpaid principal balance accrues at a rate of 10% per annum, computed on the basis of the actual number of days elapsed and a year of 365 days. Unless earlier converted into shares of Equity Securities, the principal and accrued interest will be due and payable by the Company on demand by the Holders at any time after the earlier of (i) the Maturity Date (as defined in each Agreement) and (ii) the closing of the Next Equity Financing (as defined below). The stated Maturity Date was extended on October 24, 2023, under the same terms, until October 31, 2024.

The Notes will automatically convert into the type of Equity Securities issued in the Next Equity Financing upon closing. The number of shares of such Equity Securities to be issued will be equal to the quotient obtained by dividing the outstanding principal and unpaid accrued interest due on the Note on the date of conversion of 80 –87.5% of the price paid per share for Equity Securities by the investors in the Next Equity Financing. Equity Securities refers to Company’s common stock or preferred stock and Next Equity Financing refers to the next sale (or series of related sales) by the Company of its equity securities from which the Company receives gross proceeds of not less than $3,000,000 (including the aggregate amount of debt securities converted into Equity Securities upon conversion or cancellation of promissory notes) or $5,000,000, depending upon the signed agreement terms.

In the event that the Company raises aggregate additional cash proceeds of at least $3,000,000 or $5,000,000 through the sale of the Company’s equity securities, excluding the sales or conversions of Notes under the Agreement, the outstanding principal amount due will automatically, and without any action on part of the holder, be converted into fully paid and non-assessable units of the Company’s equity stock sold in such qualified financing at 12.5% of the equity stock conversion price. The Company, at its option, may pay all accrued, but unpaid, interest and other charges in cash or by the issuance of additional equity stock at a rate of the applicable conversion price.

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.

The convertible debt balance on December 31, 2024 and December 31, 2023 is summarized as follows:

Group B

Commencing in May 2020, the Company entered into an unsecured Subordinated Convertible Promissory Note Agreement (the “Agreements”) with certain lenders (together, the “Holders” or individually, the “Holder”), pursuant to which the Company issued a Subordinated Convertible Promissory Note (individually the “Note” or together the “Notes”) to the Holders, principally the investors brought in by an investment bank. Interest on the unpaid principal balance accrues at a rate of 6% per annum, computed on the basis of the actual number of days elapsed and a year of 365 days. Unless earlier converted into shares of Equity Securities, the principal and accrued interest will be due and payable by the Company on demand by the Holders at any time after the earlier of (i) the Maturity Date (as defined in each Agreement) and (ii) the closing of the Next Equity Financing (as defined below). The stated Maturity Date was extended October 24, 2023, under the same terms, until October 31, 2024.

The Notes will automatically convert into the type of Equity Securities issued in the Next Equity Financing upon closing. The number of shares of such Equity Securities to be issued will be equal to the quotient obtained by dividing the outstanding principal and unpaid accrued interest due on the Note on the date of conversion of 80% of the price paid per share for Equity Securities by the investors in the Next Equity Financing. Equity Securities refers to Company’s common stock or preferred stock and Next Equity Financing refers to the next sale (or series of related sales) by the Company of its equity securities from which the Company receives gross proceeds of not less than $10,000,000 (including the aggregate amount of debt securities converted into Equity Securities upon conversion or cancellation of promissory notes).

In the event that the Company raises aggregate additional cash proceeds of at least $10,000,000 through the sale of the Company’s equity securities, excluding the sales or conversions of Notes under the Agreement, the outstanding principal amount due will automatically, and without any action on part of the holder, be converted into fully paid and non-assessable units of the Company’s equity stock sold in such qualified financing at 12.5% of the equity stock conversion price.

The Company evaluated the Notes in accordance with ASC 480 and determined the Notes are considered share-settled debt and should be recorded as a liability.

For the Years Ended December 31, 2024, and 2023

Group D

Commencing in November 2022, the Company entered into an unsecured Subordinated Convertible Promissory Note Agreement (the “Agreements”) with certain lenders (together, the “Holders” or individually, the “Holder”), pursuant to which the Company issued a Subordinated Convertible Promissory Note (individually the “Note” or together the “Notes”) to the Holders, principally the Investors brought in by an investment bank.

The Notes will automatically convert into the type of Equity Securities issued in the Next Equity Financing upon closing. The number of shares of such Equity Securities to be issued will be equal to the quotient obtained by dividing the outstanding principal and unpaid accrued interest due on the Note on the date of conversion of 50% of the price paid per share for Equity Securities by the investors in the Next Equity Financing. Equity Securities refers to Company’s common stock or preferred stock and Next Equity Financing refers to the next sale (or series of related sales) by the Company of its equity securities from which the Company receives gross proceeds of not less than $10,000,000 (including the aggregate amount of debt securities converted into Equity Securities upon conversion or cancellation of promissory notes).

In connection with the Group D Convertible Notes, the Company agreed to issue an additional 125,000 shares of common stock to the Group D Holders, prorated based on such Holder’s investment amount, as an inducement for their investment in the Group D Convertible Notes.

The Company evaluated the Notes in accordance with 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 number of shares of such Equity Securities to be issued will be equal to the quotient obtained by dividing the outstanding principal and unpaid accrued interest due on the Note on the date of conversion of 50% of the price paid per share for Equity Securities by the investors in the Next Equity Financing. Equity Securities refers to Company’s common stock or preferred stock and Next Equity Financing refers to the next sale (or series of related sales) by the Company of its equity securities from which the Company receives gross proceeds of not less than $10,000,000 (including the aggregate amount of debt securities converted into Equity Securities upon conversion or cancellation of promissory notes).

In the event that the Company raises aggregate additional cash proceeds of at least $10,000,000 through the sale of the Company’s equity securities, excluding the sales or conversions of Notes under the Agreement, the outstanding principal amount due will automatically, and without any action on part of the holder, be converted into fully paid and non-assessable units of the Company’s equity stock sold in such qualified financing at 50% of the equity stock conversion price. In connection with the Group E Notes, the Company agreed to issue an additional 68,750 shares of common stock to the Group E Holders, prorated based on such Holder’s investment amount as an inducement for their investment in the Group E Notes.

The Company evaluated the Notes in accordance with 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.

The convertible debt balance at December 31, 2024 and December 31,2023 is summarized as follows:

Group F

Commencing in June 2023, the Company entered into an unsecured Subordinated Convertible Promissory Note Agreement (the “Agreements”) with certain lenders (together, the “Holders” or individually, the “Holder”), pursuant to which the Company issued a Subordinated Convertible Promissory Note (individually the “Note” or together the “Notes”) to the Holders, principally the investors brought in by an investment bank. Interest on the unpaid principal balance accrues at a rate of 6% per annum, computed on the basis of the actual number of days elapsed and a year of 365 days. Unless earlier converted into shares of Equity Securities, the principal and accrued interest will be due and payable by the Company on demand by the Holders at any time after the earlier of (i) the Maturity Date (as defined in each Agreement) and (ii) the closing of the Next Equity Financing (as defined below). The stated Maturity Date was extended October 24, 2023, under the same terms, until October 31, 2024.

The Notes will automatically convert into the type of Equity Securities issued in the Next Equity Financing upon closing. The number of shares of such Equity Securities to be issued will be equal to the quotient obtained by dividing the outstanding principal and unpaid accrued interest due on the Note on the date of conversion of 50% of the price paid per share for Equity Securities by the investors in the Next Equity Financing. Equity Securities refers to Company’s common stock or preferred stock and Next Equity Financing refers to the next sale (or series of related sales) by the Company of its equity securities from which the Company receives gross proceeds of not less than $10,000,000 (including the aggregate amount of debt securities converted into Equity Securities upon conversion or cancellation of promissory notes).

In the event that the Company raises aggregate additional cash proceeds of at least $10,000,000 through the sale of the Company’s equity securities, excluding the sales or conversions of Notes under the Agreement, the outstanding principal amount due will automatically, and without any action on part of the holder, be converted into fully paid and non-assessable units of the Company’s equity stock sold in such qualified financing at 50% of the equity stock conversion price. In connection with the Group F Notes, the Company agreed to issue an additional 214,594 shares of common stock to the Group F Holders, prorated based on such Holder’s investment amount, as an inducement for their investment in the Group F Notes.

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.

The convertible debt balance at December 31, 2024 and December 31,2023 is summarized as follows:

Redemption Liability

The fair value of the redemption liability is calculated under Level 3 of the fair value hierarchy, is determined based upon a Probability-Weighted of Expected Returns Model (“PWERM”). This PWERM was determined to be the most appropriate method of estimating the value of possible redemption or conversion outcomes over time, since the Company has not entered into a priced equity round through December 31, 2024. The fair value of the redemption liability is calculated using the initial value of the convertible note less the debt discount rate of 12.5% in Group A,20% in Groups B and C, and 50% in Groups D, E and F. The redemption liability is then amortized over the remaining life of the note, utilizing the interest rates of 10% and 6% respectively for the groups. The life of each note in Group A is for a set period of 3 years, and is variable in Groups B, C, D, E and F with a range of 12 months to 3 years. The Company retains the option to negotiate an extended maturity date for Groups B, C, D, E and F. The new embedded redemption values were $0 for the year ended December 31, 2024, and $1,541,250 for the year ended December 31, 2023, respectively. 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. The redemption liability was closed to stockholders’ equity on such date.

The redemption liability is re-measured at each period end and is summarized as follows:

Fees Associated with Convertible Debt Raise

The fees associated with the convertible debt raise are legal and investment fees associated with the issuance of the convertible notes for Groups A, B, C, and D. There were no related parties who received these fees. The fees are amortized over the life of the convertible note utilizing an interest rate of 10% for Group A and 6% for Groups B, C, and D. The debt issuance liability is re-measured at each period end and is summarized in the table below.

Make-whole liability — Shares due Noble Capital

In March 2020, the Company signed a new advisory agreement with Noble Capital, in lieu of cash remuneration and the company agreed to issue 4% of the Company’s shares, with an anti-dilution clause. The make-whole liability represents the shares earned for the anti-dilution of their stock position over 2020 and 2021. The 2021 year-end had the Company owning an aggregate of 233,202 shares valued in the amount of $408,413, after issuing 200,000 shares in 2020. In 2021, the Company recorded an associated expense to advisory fees of $152,482 to recognize the share value earned on the anti-dilution compensation in 2021. In 2022, the Company set aside 70,624 shares to satisfy the anti-dilution clause. In 2022, the Company recorded an associated expense to advisory fees of $282,496 to recognize the share value earned on the anti-dilution compensation in the 2022.

For the years ended December 31, 2024 and 2023, the Company recorded an additional 0 and 16,672 shares, respectively, with an associated expense to advisory fees of $0 and $66,688, respectively, on the anti-dilution compensation.

On July 1, 2023, the make-whole liability for Noble Capital was determined to be contractually nullified. The Company unwound the liability, and it is reflected in our Statement of Stockholders’ Deficit.

Noble Capital and the Company settled on various investment fees in dispute, as well as the shares of the Company’s common stock related to the anti-dilution clause that expired in September 2024. Noble Capital was awarded 320,033 shares of common stock and $50,000 in cash.

Make-whole liability — Shares Officers & Directors

In January 2023,350,000 shares of Class A common stock were issued to officers, key employees, key advisors and directors, leaving 20,000 shares in the balance to be issued to Joacim Borg, a director with a value of $80,000.

On March 1, 2023, the Company hired Alan Musso, former CFO, and, as part of his compensation contract, he was awarded 12,500 shares of common stock with a value of $4.00 per share, the $50,000 in compensation of which is reflected in the make-whole stock liability.

Alan resigned on June 30, 2023, and Christopher Acevedo, current CFO, took his position. Mr. Acevedo was awarded the balance of Mr. Musso’s shares upon the successful initial public offering.

The Company’s make-whole share liability is summarized in the table below as of September 30, 2024.

The Company issued all of the make-whole shares due to the director and officers in October 2024, and, therefore, the current balance due is 0 shares.

Warrants for Placement Agent — Noble Capital

In March 2020, the Company signed a new advisory agreement with Noble Capital, in lieu of cash remuneration it was provided a 10% warrant fee, in addition to cash remuneration on debt raises from Noble procured investments.

An investor lent the Company $150,000 on June 28, 2024. The note is a demand note, carrying interest at 8% and was also used for working capital purposes. The Company repaid these loans, including accrued interest thereon, in August 2024.

NOTE 5 — TEDCO GRANT

In May of 2021, the Company received the first oftwo tranches from TEDCO’sRural & Underserved Business Recovery from Impact of COVID-19 (RUBRIC) Grantin the amount of $50,000. A second tranche of $50,000 was received in October 2021 for a total reimbursable grant amount of $100,000. The Company is 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 total. The Company has 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, the Company will receive a 10% reduction of the royalty cap percentage for each year prior to the expiration of thefive-year reimbursement period that the grant is repaid in full. If the Company ceases to meet eligibility requirements the reimbursement obligation will become due to TEDCO immediately; however, the discount for meeting the obligation will still apply.

NOTE 6 — INCOME TAXES

Significant components of the Company’s deferred tax assets and liabilities were as follows:

Thefederal income tax rate used for the years ended December 31, 2024 and 2023 was 21%. The Maryland rate was 8.25%.

For years ended December 31, 2024 and December 31, 2023, the Company had federal net operating loss (“NOL”) 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. The Company has provided a valuation allowance to offset the deferred tax assets due to the uncertainty of realizing the benefits of the net deferred tax asset.

The Company’s issuances of common stock have resulted in ownership changes as defined by Section 382 of the Code; however, the Company has 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 the Company’s 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. The Company is 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.

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 2024. The Company believes the claim is meritless as it awaits a formal meeting.

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.

Liquidation— One times the original issue price of the New Preferred Stock plus declared but unpaid dividends on each share of New Preferred Stock (or, 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.

NOTE 9 — REDEEMABLE PREFERRED STOCK, MEZZAININE EQUITY AND WARRANT LIABILITY

Securities Purchase Agreement

On December 24, 2024, the Company entered into the Purchase Agreement with various institutional and accredited investors. The Company completed the initial closing on December 31, 2024 and sold an aggregate of 1,512,500 immediately separable units (the “Units”), each Unit consisting of (i) one share of the Company’s Series A Senior Convertible Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock”), and (ii) a warrant to purchaseone share of common stock (each, a “Warrant” and, collectively, the “Warrants”), at a price per Unit of $4.00. The Warrant has an exercise price of $4.40 per share, subject to adjustment therein, and a term of five years from the date stockholder approval of the common stock issuances contemplated by the Purchase Agreement is obtained. The gross proceeds from the initial closing to the Company, before deducting transaction fees and other estimated expenses, was 6,050,000.

Based on the terms of the Series A Preferred Stock and the Company’s Certificate of Designation, and in accordance with ASC 480, the Series A Preferred Stock is accounted for as mezzanine equity due to the redemption feature upon a deemed liquidation event: (i) a merger or consolidation, or (ii) the sale, lease, transfer or other disposition of substantially all the assets of the Company. The initial cash proceeds of $6,050,000 were allocated to the Warrants and the residual proceeds were allocated to the Series A Preferred Stock.

NOTE 9 — PREFERRED STOCK 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 to 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 in the model: (1) a variable exercise price with a floor of $4.40 per share, (2) current common stock price of $4.28 per share, (3) discount rate of 4.38%, and (4) expected stock price volatility of 24.90%. As of December 31, 2024, the carrying value of the Warrant liability in aggregate was $1,971,975.

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. Because the Series A Preferred Stock is classified as a mezzanine equity, the Company will record a deemed dividend for the accretion of the Series A Preferred Stock to carrying value in accordance with ASC 480. The following table reflects the allocation of the cash proceeds, which results in a deemed dividend recorded in the consolidated statement of operations in the amount of $1,971,975 for the year ended December 31, 2024.
