Shuttle Pharmaceuticals Holdings, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

June 30, 2024

Note 1 –Organization and Liquidity

Organization and Line of Business

Shuttle Pharmaceuticals Holdings, Inc. (“we”, “us”, “our”, the “Company”) was originally formed as Shuttle Pharmaceuticals, LLC in the State of Maryland on December 18, 2012. On August 12, 2016, the Company filed articles of conversion with the State of Maryland to convert from an LLC to a C corporation, at which time the Company changed its name to Shuttle Pharmaceuticals, Inc. (“Shuttle”). In connection with the conversion the Company issued 5,625,000 shares of common stock in exchange for 100% of the outstanding membership interests in Shuttle prior to conversion. On June 4, 2018, Shuttle completed a reverse merger with Shuttle Pharmaceuticals Holdings, Inc. (then known as Shuttle Pharma Acquisition Corp, Inc.), a Delaware corporation, pursuant to which Shuttle, our operating entity, became a wholly owned subsidiary of the Company. All share numbers referenced herein reflect a 1-for-8 reverse split of our common stock on a post-split basis, which was effective as of August 13, 2024 (see Note 2).

The Company’s primary purpose is to develop and commercialize unique drugs for the sensitization of cancers and protection of normal tissues, with the goal of improving outcomes for cancer patients receiving radiation therapy. Shuttle has deployed its proprietary technology to develop novel cancer immunotherapies, producing a pipeline of selective HDAC inhibitors for cancer and immunotherapy applications. The Company’s HDAC platform is designed to target candidate molecules with potential roles in therapeutics beyond cancer, including autoimmune, inflammatory, metabolic, neurological and infectious diseases. The Company’s Ropidoxuridine product, which is used with radiation therapy to sensitize cancer cells, was initially funded by a Small Business Innovation Research (“SBIR”) contract provided by the National Cancer Institute (“NCI”), a unit of the National Institutes of Health (“NIH”). Ropidoxuridine has been further developed though the Company’s collaborations with scientists at the University of Virginia for use in combination with proton therapy to improve patient survival. Historically, and prior to the Company’s initial public offering in September 2022, the Company has obtained funding to develop products through NIH grants, including a product to predict late effects of radiation with metabolite biomarkers and develop prostate cancer cell lines in health disparities research.

The production and marketing of the Company’s products and its ongoing research and development activities will be and are subject to extensive regulation by numerous governmental authorities in the United States. Prior to marketing in the United States, any products or combination of products developed by the Company must undergo rigorous preclinical (animal) and clinical (human) testing and an extensive regulatory approval process implemented by the Food and Drug Administration (“FDA”) under the Food, Drug and Cosmetic Act. There can be no assurance that the Company will not encounter problems in its clinical trials that will cause the Company or the FDA to delay or suspend the clinical trials.

The Company’s success will depend in part on its ability to obtain patents and product license rights, maintain trade secrets, and operate without infringing on the proprietary rights of others, both in the United States and in other countries. There can be no assurance that patents issued to or licensed by the Company will not be challenged, invalidated or circumvented, or that the rights granted thereunder will provide proprietary protection or competitive advantages to the Company now or in the future.

Liquidity and Going Concern

Our unaudited condensed consolidated financial statements are prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has incurred losses since inception and has a net loss of approximately $3.8 million andno revenues for the six months ended June 30, 2024 and has working capital of approximately $1.1 million as of June 30, 2024. In addition, the convertible note payable outstanding at June 30, 2024 includes covenants and certain cash payment requirements. On July 12, 2024, the Company informed the investor of its convertible note that the Company’s expected restatement of its financial statements for the years ended December 31, 2022 and 2023 constituted an event of default under the terms of the convertible note. On August 6, 2024, the Company paid $0.6 million to the investor of the convertible note and received a waiver from the investor related to the default. The funds paid are restricted and will be held as collateral to the balance owed under the convertible note (see Note 9). These conditions, and the Company’s ability to comply with such conditions, raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the unaudited condensed consolidated financial statements are issued.

In January 2023, the Company entered into a securities purchase agreement with an institutional investor through which the Company sold a convertible note with a principal value of $4.3 million, along with afour-year warrant to purchase 127,260 shares of common stock, exercisable at $18.80 per share, providing the Company with approximately $3.6 million in net proceeds. To date, the warrant has not yet been exercised. However, the Company’s existing cash resources, marketable securities and the cash received from the equity offering and convertible note are not expected to provide sufficient funds to carry out the Company’s operations and clinical trials through the next twelve months.

The IPO and subsequent capital raise have supported operations, the manufacture of drug product and FDA approval of the IND for the Phase II clinical trial of Ropidoxuridine and radiation therapy in glioblastoma. The FDA recommended and the Company agreed to an expansion of the clinical trial, necessitating additional capital to complete the trial as well as fund ongoing operations. As a result, management had initiated a $4.5 million rights offering and submitted an application for a SBIR grant for non-dilutive funding for pre-clinical project through the NIH. The Company is also currently pursuing other financing. The ability of the Company to continue as a going concern is dependent upon its ability to successfully raise additional equity or debt financing to allow it to fund ongoing operations, conduct clinical trials and bring a drug candidate to commercialization to generate revenues.

The accompanying unaudited condensed consolidated financial statements do not include any adjustments to reflect the future effects on the recoverability and classification of assets or the amounts and classification of liabilities if the Company is unable to continue as a going concern.

Note 2 –Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements and with the instructions to Form 10-Q and Rule 8-03 of Regulation S-X of the United States Securities and Exchange Commission (“SEC”). Accordingly, they do not contain all information and notes required by GAAP for annual financial statements. A complete discussion of the Company’s significant accounting policies is included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements contain all of the adjustments necessary to present the financial position of the Company as of June 30, 2024 and the results of operations and cash flows for the periods presented. The accompanying condensed consolidated financial statements of the Company have not been audited by the Company’s independent registered public accounting firm, except that the year-end consolidated balance sheet was derived from audited financial statements. The results of operations for the six months ended June 30, 2024 are not necessarily indicative of the operating results for the full fiscal year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with the restated financial statements and related notes thereto for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K/A filed with the SEC on September 3, 2024.

Reverse Stock Split

On August 13, 2024, in order to meet Nasdaq’s minimum bid price requirement of $1.00 per share (the “Minimum Bid Price Requirement”), the Company effectuated a 1-for-8 reverse stock split of its issued and outstanding common stock, rounding up to account for any fractional shares (the “Reverse Stock Split”). The Reverse Stock Split had no effect on the Company’s authorized shares of common stock or preferred stock and the par value will remain unchanged at $0.00001, respectively. Following the reverse stock split on August 13, 2024, the Company had a total of 2,111,235 shares issued and outstanding (or 2,106,233 on a post-split basis as of June 30, 2024). All common stock share, option, warrant and per share amounts (except our authorized but unissued shares) have been retroactively adjusted in these financial statements and related disclosures.

Basis of Consolidation

The unaudited condensed consolidated financial statements have been prepared on a consolidated basis with those of the Company’s wholly-owned subsidiaries, Shuttle Pharmaceuticals, Inc. and Shuttle Diagnostics Inc. All intercompany transactions and balances have been eliminated.

Correction of an Immaterial Error in the Prior Period Financial Statements

During the fourth quarter of 2023, the Company determined that the prior year consolidated financial statements had a misstatement caused by an immaterial classification error of certain research and development expenses in accordance with Accounting Standards Codification (“ASC”) 730. As a result, certain prior year amounts have been corrected for consistency with the current year presentation. The Company assessed the materiality of this change in presentation on prior period consolidated financial statements in accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” (ASC Topic 250, Accounting Changes and Error Corrections). Based on this assessment, the Company concluded that these error corrections in its unaudited condensed consolidated statements of operations are not material to any previously presented financial statements based upon overall considerations of both quantitative and qualitative factors. The corrections had no impact on the unaudited condensed consolidated balance sheet, unaudited condensed consolidated statements of cash flows, or unaudited condensed consolidated statement of changes in stockholders’ equity, to these financial statements, or for any previously presented interim or annual financial statements. Further, the corrections did not result in a change in quarterly or year-to-date operating losses, basic or diluted earnings per share, or working capital. The quarterly correction required for the three and six months ended June 30, 2023 was $93,708 and $182,715, respectively. Accordingly, the Company corrected the previously reported immaterial error for the three and six months ended June 30, 2023 in this Quarterly Report on Form 10-Q.

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company regularly evaluates estimates and assumptions. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected. Significant estimates are contained in the accompanying unaudited condensed consolidated financial statements for the recognition of research and development expenses, valuation of warrants and valuation of bifurcated derivative liabilities and other financial instruments.

Cash and Cash Equivalents

Cash and cash equivalents include cash in bank accounts and money market funds with maturities of less than three months from inception, which are readily convertible to known amounts of cash and which, in the opinion of management, are subject to an insignificant risk of loss in value. As of June 30, 2024 and December 31, 2023, cash and cash equivalents consisted of the following:

Periodically, the Company may carry cash balances at financial institutions in excess of the federally insured limit of $250,000 per institution. The amount in excess of the FDIC insurance as of June 30, 2024 was approximately $0.4 million. The Company has not experienced losses on these accounts and management believes, based upon the quality of the financial institutions, that the credit risk with regard to these deposits is not significant.

Marketable Securities

Our investments in debt securities are carried at fair value. Investments in debt securities that are not classified as held-to-maturity are carried at fair value and classified as either trading or available-for-sale. Realized and unrealized gains and losses on trading of debt securities are charged to income.

The marketable securities held by the Company, which are classified as trading marketable securities, consisted of an outstanding balance of $1.6 million and $2.9 million as of June 30, 2024 and December 31, 2023, respectively. During the three months ended June 30, 2024 and 2023, the Company recognized interest income of $14,158 and $19,267, realized gains of $39,683 and $1,744, and unrealized loss of $27,964 and unrealized loss of $26,534, respectively. During the six months ended June 30, 2024 and 2023, the Company recognized interest income of $35,611 and $35,955, realized gains of $43,720 and $1,744, and unrealized loss of $28,670 and unrealized gain of $11,528, respectively.

Fair Value of Financial Instruments

The Company follows accounting guidelines on fair value measurements for financial instruments measured on a recurring basis, as well as for certain assets and liabilities that are initially recorded at their estimated fair values. Fair Value is defined as the exit price, or the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The Company uses the following three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs to value its financial instruments:

Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires the Company to make judgments and consider factors specific to the asset or liability. The use of different assumptions and/or estimation methodologies may have a material effect on estimated fair values. Accordingly, the fair value estimates disclosed, or initial amounts recorded, may not be indicative of the amount that the Company or holders of the instruments could realize in a current market exchange.

The carrying amounts of the Company’s financial instruments including cash and cash equivalents, prepaid expenses, accounts payable and accrued liabilities approximate fair value due to the short-term maturities of these instruments.

Set out below are the Company’s financial instruments that are required to be remeasured at fair value on a recurring basis and their fair value hierarchy as of June 30, 2024 and December 31, 2023:

Derivative Financial Instruments

The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risks. We evaluate all of our financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the unaudited condensed consolidated statements of operations. For our liability classified derivative financial instruments, the Company used a Monte Carlo valuation model to value the derivative instruments at inception and on subsequent valuation dates. For our equity classified derivative financial instruments, we used a Black-Scholes option-pricing model at the grant date to value the derivative instrument. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the unaudited condensed consolidated balance sheets as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within twelve (12) months of the balance sheet date.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC 480,Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815,Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the unaudited condensed consolidated statements of operations. The fair value of the warrants is estimated using a Black-Scholes pricing model or a Monte Carlo simulation.

Research and Development Expenses

Research and development expenses are charged to expense as incurred. Research and development expenses include, but are not limited to, product development, clinical and regulatory expenses, payroll and other personnel expenses, which include a certain portion of our chief executive officer, chief operating officer, chief financial officer and directors’ compensation. For the three and six months ended June 30, 2024 and 2023, a portion of personnel-related expenses and stock-based compensation expense for these individuals totaling $0.1 million and $0.3 million, respectively, and $0.2 million and $0.6 million, respectively, was included within research and development due to their active involvement in the research and development activities, materials, supplies, related subcontract expenses, and consulting costs.

Regarding the accounting treatment for reimbursements, GAAP provides limited guidance on the accounting for government grants received by for-profit companies. In accordance with ASC Topic 832,Government Assistance, as adopted January 1, 2022, we disclose certain types of government assistance received in the notes to the consolidated financial statements that includes: a) the nature of the transaction including the nature of the assistance being given, b) the accounting policies being used to account for the transaction and c) other provisions of relevance, where required. Depending on the type of grant or contract, we understand there is more than one acceptable alternative for the accounting treatment – a reduction of costs, a deferred credit to be amortized, revenue or other income. The Company has concluded that reimbursements received for R&D expenses incurred, are more akin to a reduction of costs and applies reimbursements against incurred research costs. There were no reimbursements received for the six months ended June 30, 2024 and 2023.

Net Loss Per Common Stock

Net loss per share of common stock requires presentation of basic earnings per share on the face of the unaudited condensed consolidated statements of operations for all entities with complex capital structures and requires a reconciliation of the numerator and denominator of the basic earnings per share computation. In the accompanying unaudited condensed consolidated financial statements, basic loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the year. Diluted earnings per share is computed by dividing net income by the weighted average number of shares of common stock and potentially dilutive outstanding shares of common stock during the period to reflect the potential dilution that could occur from common shares issuable through contingent share arrangements, stock options and warrants unless the result would be antidilutive.

The dilutive effect of restricted stock units subject to vesting and other stock-based payment awards is calculated using the “treasury stock method,” which assumes that the “proceeds” from the exercise of these instruments are used to purchase common shares at the average market price for the period. The dilutive effect of convertible securities is calculated using the “if-converted method.” Under the if-converted method, securities are assumed to be converted at the beginning of the period, and the resulting shares of common stock are included in the denominator of the diluted calculation for the entire period being presented.

For the six months ended June 30, 2024 and 2023, the following common stock equivalents were excluded from the computation of diluted net loss per share as the result of the computation was anti-dilutive.

Deferred Offering Costs

Pursuant to ASC 340-10-S99-1, costs directly attributable to an offering of equity securities are deferred and would be charged against the gross proceeds of an offering as a reduction of additional paid-in capital. Deferred offering costs may consist of underwriting, legal, accounting, and other expenses incurred through the balance sheet date that are directly related to a proposed public offering. Should the proposed public offering prove to be unsuccessful, any deferred costs, as well as additional expenses to be incurred, will be expensed.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting Topic 280, “Segment Reporting-Improvements to Reportable Segment Disclosures,” which allows disclosure of one or more measures of segment profit or loss used by the chief operating decision maker to allocate resources and assess performance. Additionally, the standard requires enhanced disclosures of significant segment expenses and other segment items, as well as incremental qualitative disclosures on both an annual and interim basis. This guidance is effective for annual reporting periods beginning after December 15, 2023, and interim reporting periods after December 15, 2024. Early adoption is permitted and retrospective application is required for all periods presented. The adoption of this new guidance is not expected to have a significant impact on our consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes Topic 740, “Income Tax-Improvements to Income Tax Disclosures,” which requires enhanced disclosures, including specific categories and disaggregation of information in the effective tax rate reconciliation, disaggregated information related to income taxes paid, income or loss from continuing operations before income tax expense or benefit, and income tax expense or benefit from continuing operations. This guidance is effective for annual reporting periods beginning after December 15, 2024. Early adoption is permitted and should be applied on a prospective basis, however retrospective application is permitted. The Company is currently evaluating the impact of adopting this guidance on its consolidated and condensed financial statements and disclosures included within notes to consolidated and condensed financial statements.

Note 3 –Leases

Operating lease right-of-use (“ROU”) assets and liabilities are recognized at the present value of the future lease payments as of the lease commencement date. Operating lease expense is recognized on a straight-line basis over the lease term.

During the six months ended June 30, 2023, the Company had a lease agreement which allowed for the use of a laboratory facility for a monthly payment of $6,480. The laboratory lease commenced on October 1, 2018 and expired on October 31, 2023.

The Company currently has a lease agreement which allows for the use of a laboratory facility, entered into on February 16, 2023, with base rent of $7,206 per month for a period of 64 months, which increases at the rate of 3% per year, that commenced June 1, 2023. The lease included a six-month 50% rent abatement upon commencement. Additional common area maintenance (“CAM”) fees are charged monthly and revised annually. The estimated monthly CAM fees are $3,300 per month for the first year of the lease, which are being expensed as incurred. An irrevocable letter of credit (“LOC”) for the security deposit of $43,234 and base rent of $3,891, including 50% abatement, and $3,315 of CAM cost, was due and paid on execution of the lease agreement. Alexandria Real Estate (ARE-QRS-CORP) is the beneficiary of the LOC, and the expiry date of the LOC is March 1, 2025.

The following summarizes the ROU lease expense components and cash flow information for the Company’s operating leases:

Supplemental balance sheet information related to operating leases was as follows:

Future non-cancelable minimum lease payments under the operating lease liability as of June 30, 2024, are as follows:

Note 4 –Notes Payable-Related Party

During the three and six months ended June 30, 2023 the Company incurred $2,588 and $6,825, respectively, in interest expense. During the three and six months ended June 30, 2023 principal payments of $139,229 and $685,473, respectively, and accrued interest of $25,917 and $102,373 were paid, respectively, on notes to related parties. The principal and accrued interest for these notes were fully paid by December 31, 2023.

Note 5 –Convertible Notes and Notes Payable

Alto Opportunity Master Fund, SPC

On January 11, 2023, the Company entered into a securities purchase agreement (the “SPA”) with Alto Opportunity Master Fund, SPC – Segregated Master Portfolio B, a Cayman entity (the “Investor”), pursuant to which the Company sold to the Investor a $4,300,000 convertible note (the “Alto Convertible Note”) and warrant (the “Warrant”) to purchase 127,260 shares of common stock, exercisable at $18.80 per share, in exchange for gross proceeds of $3,935,000 (the “Investment Amount”) (See Note 7). The Company determined that the Warrant contains a net cash settlement feature at inception and categorized the Warrant as a liability in the accompanying unaudited condensed consolidated financial statements. The Alto Convertible Note matures on March 11, 2025, but may be extended at the option of the noteholder. The Alto Convertible Note amortizes on a monthly basis and the Company can make such monthly amortization payments in cash or, subject to certain equity conditions, in registered shares of common stock or a combination thereof. Installments may be deferred by the noteholder, resulting in a variable interest rate. However, the effective interest rate is approximately 218% based on the internal rate of return calculated on a series of cash flows that occur at regular intervals. For equity repayment, the Alto Convertible Note is convertible into shares of common stock at a price per share equal to the lower of (i) $18.80, (ii) 90% of the three lowest daily VWAPs of the 15 trading days prior to the payment date, or (iii) 90% of the VWAP of the trading day prior to payment date. The noteholder may convert at any time at a fixed price of $18.80 per share. The noteholder has an acceleration of installment amount conversion option (the “Acceleration Option”), whereby the noteholder, with certain share percentage limitations, can convert to common stock any outstanding installment amount at an amount equal to the installment amount plus five times (5x) the installment amount at any time. The Company has determined the Acceleration Option is an embedded derivative within the host instrument and has bifurcated it from the host instrument and recorded it as a derivative liability valued at $1,442,000 at inception, using a Monte Carlo simulation model (Note 7). The Convertible Note is repayable over 26 months and bears interest at the rate of 5% per annum. Additionally, the note contains certain redemption options and “Make Whole” provisions.

In conjunction with entry into the SPA, the Company entered into a series of related agreements, including a security agreement (the “Security Agreement”), an intellectual property security agreement (the “IP Security Agreement”) and a subsidiary guaranty (the “Subsidiary Guaranty”). The security agreements and guaranty allow, among other things, for the Investor to have a security interest in and place a lien on all of the Company’s assets and intellectual property until such time as the Alto Convertible Note is paid off. In addition, the SPA called for the Company to enter into a springing deposit account control agreement (the “Springing DACA”), which, in the event the Company defaults on its repayment of the Alto Convertible Note, would allow the Investor to assume control of the Company’s bank account only with regard to any funds remaining outstanding under the Alto Convertible Note. As such, in conjunction with entry into the SPA, the Company established a separate bank account in which it deposited the Investment Amount and pursuant to which the Company, the Investor and the bank holding the Investment Amount, First Republic Bank, entered into the Springing DACA agreement. As the Investment Amount had been held at First Republic Bank, in light of certain banking crises then affecting smaller banks, on March 12, 2023, the Company and the Investor moved the Investment Amount from First Republic Bank, after which time the Springing DACA was no longer in effect. Further, pursuant to amendments to the SPA entered into in May and June of 2023, the Company and the Investor agreed that all of the Investment Amount would be released to the Company and the relevant provision of the SPA which required the Springing DACA would no longer be deemed applicable. In addition, the Company granted the Investor the option to purchase up to an additional $10.0 million in convertible notes and warrants on substantially the same terms as the Alto Convertible Note and Warrant, excluding the Springing DACA requirement, with such option to be effective through December 31, 2025. The agreement offers the investor an opportunity to participate in future capital raises at substantially similar terms as the January 11, 2023 agreement. The Company expects that such subsequent convertible notes and warrants would be issued on substantially similar terms as the January 11, 2023 initial agreement, as amended, thus providing the Company the opportunity to negotiate certain aspects of the agreement.

Boustead Securities, LLC (“Boustead”) served as a placement agent for the Alto Convertible Note and Warrant offering and received $345,000 cash compensation and a warrant to purchase 8,909 shares of common stock, exercisable at $18.80 per share. The Boustead warrant was determined to be an equity instrument valued on a non-recurring basis. The Company used the Black Scholes valuation model using a term offive years, volatility of 110%, a risk-free rate of 3.53% for a value of $99,543.

The Company allocated the finance costs related to the Boustead placement agent fee of $345,000, based on the relative fair market values of the Convertible Note and warrants issued. The allocation of the financing costs applied $232,027 to the debt component as a debt discount that is being amortized to interest expense over the term of the Convertible Note, $104,245 to the warrant derivative liability component, expensed as a finance fee, and $8,727 to the equity warrant as a reduction in additional paid in capital.

The Company allocated to the debt component of the note an original discount of $300,000, legal fees of $65,000, $215,000 for additional interest fees on day one added to note principal, $1,442,000 for the accelerated conversion feature, and $1,288,543 for the fair value of warrants, resulting in an additional $3,310,543 debt discount that is being amortized to interest expense over the term of the Alto Convertible Note.

During the three and six months ended June 30, 2024, the Company recorded interest expense of $430,685 and $928,200, respectively, which included amortization of debt discount as interest expense of $386,505 and $832,014, respectively. During the three and six months ended June 30, 2024, the Company settled $0 and $235,200 of principal, and settled $0 and $18,783 of accrued interest, which settlements were made in the form of 0 and 78,197 shares of common stock. The Company also settled for cash during the six months ended June 30, 2024 $501,667 of principal and $56,958 of accrued interest for a total of $558,628 of principal and interest paid in cash.

During the three and six months ended June 30, 2023, the Company recorded interest expense of $729,351 and $1,328,682 respectively, which included amortization of debt discount as interest expense of $549,125 and $1,012,177 respectively. During the three and six months ended June 30, 2023, the Company paid $1,527,750 and $1,593,900 of principal, respectively, and paid $220,689 and $240,831, respectively, of accrued interest, which payments were made in the form of 228,489 and 234,864 shares of common stock, respectively, during the three and six months ended June 30, 2023.

As of June 30, 2024, the outstanding principal for the convertible note was $1,517,989 and the debt discount remaining was $691,754, with a net convertible note carrying value of $826,235.

Equity Incentive Plan

Our 2018 Equity Incentive Plan (the “2018 Plan”) provides for equity incentives to be granted to our employees, executive officers, directors and key advisers and consultants. Equity incentive grants may be made in the form of stock options with an exercise price of not less than the fair market value of the underlying shares as determined pursuant to the 2018 Equity Incentive Plan, restricted stock awards, other stock-based awards, or any combination of the foregoing. The 2018 Equity Incentive Plan is administered by the Company’s compensation committee. We have reserved 3,000,000 shares of our common stock for issuance under the 2018 Equity Incentive Plan. As of June 30, 2024,138,234 shares have been granted under the 2018 Equity Incentive Plan, of which 79,395 shares have vested.

Restricted Stock Units

We may grant restricted stock units (“RSU”) under our 2018 Plan. RSUs are bookkeeping entries representing an amount equal to the fair market value of one share of our common stock. Subject to the provisions of our 2018 Plan, the administrator determines the terms and conditions of RSUs, including the vesting criteria and the form and timing of payment. Notwithstanding the foregoing, the administrator, in its sole discretion, may accelerate the time at which any restrictions will lapse or be removed. RSUs granted typically vest annually in one third increments from the date of appointment.

During the three and six months ended June 30, 2024 and 2023, pursuant to agreements with officers and consultants,28,455 and 53,455, respectively and 4,291 and 7,416 RSUs, respectively with a value of $100,000 and $141,840, respectively, and $47,400 and $95,400, respectively, were granted and compensation expense for RSUs of $182,611 and $57,855, respectively, was incurred. During the three and six months ended June 30, 2024 and 2023, $13,033 and $46,986, respectively, and $41,190 and $41,190, respectively was included in compensation under Research and Development.

As of June 30, 2024, there was $190,779 of unrecognized RSU compensation cost related to non-vested stock-based compensation arrangements which is expected to be recognized over a weighted-average period of 1.97 years.

A summary of activity regarding the Restricted Stock Units issued follows:

Rights Offering and Financing Commitment

On February 7, 2024, the Company and its wholly-owned subsidiary, Shuttle Diagnostics, Inc., entered into a securities purchase agreement (the “Purchase Agreement”) with SRO, LLC, a Nevada limited liability company, pursuant to which SRO LLC agreed to commit to purchasing from the Company $2,250,000 of units from the Company, with each Unit consisting of(i) one share of the Company’s common stock, (ii) a warrant to purchase one share of the Company’s common stock exercisable at a purchase price of $18.80 per share, and (iii) a percentage of equity interest in Diagnostics such that, assuming the sale of all $2,250,000 of Units, SRO LLC will own a 22% interest in Diagnostics. Pursuant to the terms of the Purchase Agreement, the Units will be sold at a per Unit price equal to 90% of the VWAP of the Company’s common stock for the five trading days immediately preceding closing. The parties entered into the Purchase Agreement in anticipation of the Company commencing a rights offering (the “Rights Offering”) pursuant to which the Company intends to offer a total of $4,500,000 of Units to existing stockholders, which includes the $2,250,000 of Units being sold to SRO LLC, an entity which is controlled by Keith Moore, Executive Chairman of Boustead & Company Limited, an affiliate of Boustead.

The Company filed an initial registration statement on Form S-1 (the “Form S-1”) with the SEC in April 2024 related to the registration of subscription rights to purchase the Units to be sold in the Rights Offering. The Form S-1 has not been declared effective as of the date these unaudited condensed consolidated financial statements were issued. Upon the Form S-1 being declared effective, the Purchase Agreement allows SRO LLC up to 60 days to raise the initial $2,250,000, which funds will be placed in escrow with Sutter Securities, Inc. (“SSI”), an affiliate of BSL, pursuant to the terms of an escrow agreement entered into between the Company, Shuttle Diagnostics, Inc., BSL and SSI on February 7, 2024 (the “Escrow Agreement”). The funds will remain in escrow up until closing on the Rights Offering. In addition, in the event the Company fails to raise the full $4,500,000 in the Rights Offering, SRO LLC agreed to a backstop commitment pursuant to which it would have the right to purchase any remaining Units not purchased by existing Company stockholders in the Rights Offering, up to an additional $2,250,000 (the “Back-up Contingency”). Unless the parties waive the conditions to closing, in the event the full $4,500,000 is not raised, whether through SRO LLC or through the Company’s existing stockholders, the Company will not close on the offering and any funds raised and held in escrow will be returned to investors.

In conjunction with its entry into the Purchase Agreement, on February 7, 2024, the Company entered into a placement agent and advisory services agreement (the “Placement Agent Agreement”) with BSL, pursuant to which BSL and BSL’s affiliates will provide the Company with regular and customary financial consulting advice and will act as placement agent, on a best efforts basis, for the Rights Offering. In exchange for its services, BSL will receive a commitment fee equal to $112,500 upon the earlier of the Company filing the registration statement on Form S-1 registering the Rights Offering or upon such date as the Company terminates the Rights Offering, a commission equal 8% of the gross proceeds disbursed to the Company upon closing the Rights Offering, and $40,000 in diligence and related expenses.

As of June 30, 2024, the Company has incurred $142,000 in costs directly related to the planned Rights Offering and initially deferred these costs as other current assets in the unaudited condensed consolidated balance sheet. However, since that date, the Rights Offering has not been consummated and, therefore, the deferred costs have been expensed. As of June 30, 2024, there were no deferred costs recorded on the Company’s unaudited condensed consolidated balance sheet. Subsequent to June 30, 2024, the Company is pursuing other financing options.

Note 7 –Derivative Liabilities

Fair Value Assumptions Used in Accounting for Derivative Liabilities

ASC 815 requires us to assess the fair market value of derivative liabilities at the end of each reporting period and recognize any change in the fair market value as other income or expense.

In January 2023, in connection with the Alto Convertible Note, the Company issued warrants to purchase 127,260 shares of common stock, with an exercise price of $18.80 per share, valued at inception at $1,189,000 and as of June 30, 2024, at $359,919. The Company determined our derivative liabilities from the warrants issued in relation to the Alto Convertible Note do not satisfy the classification as equity instruments due to the existence of a certain net cash settlement provision that is not within the sole control of the Company. In addition, there are certain down round provisions that could reduce the exercise price if the Company issues securities at lower prices in the future.

The Company has determined the Acceleration Option is an embedded derivative within the host instrument and has bifurcated it from the host instrument and recorded it as a derivative liability valued at $1,442,000, using a Monte Carlo simulation model. The Company determined our derivative liability from the noteholder’s Acceleration Option for the Alto Convertible Note is not clearly and closely related to the host and should be thus accounted for as a bifurcated derivative liability.

The Company classified these derivative liabilities as a Level 3 fair value measurement and used the Monte Carlo pricing model to calculate the fair value as of January 11, 2023 ($2,631,000 included in debt discount) and June 30, 2024 ($360,423). Key inputs for the simulation are summarized below. The Monte Carlo simulation uses an implied VWAP for the January 11, 2023 valuation date. The implied VWAP was backsolved by setting the summation of the parts (e.g., derivatives and debt without derivatives) equal to the cash proceeds. The simulation was then iterated and manipulated to solve for the implied share price, which was approximately $12.64 per share (or an approximate 14% discount to the quoted market VWAP on January 11, 2023).

The key inputs for the Monte Carlo simulation as of June 30, 2024, were as follows:

The following table summarizes the changes in the derivative liabilities:
