Note 1 – Organization and Liquidity

Organization and Line of Business

Shuttle Pharmaceuticals Holdings, Inc. (“we,” “us,” “our,” or 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 225,000 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. Shuttle Diagnostics, Inc, a subsidiary of the Company, was formed in the State of Maryland on November 14, 2023.

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 candidate, 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 through 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 had 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 had a net loss of approximately $6.8 million and no revenues for the six months ended June 30, 2025 and working capital of approximately $3.5 million as of June 30, 2025. The Company does not expect to generate positive cash flows from operating activities in the near future.

In February 2025, the Company issued a revolving note in the principal amount of up to $2,000,000, which the Company may draw upon at its discretion from time to time. In March 2025, the Company completed an equity raise that provided $5.0 million net cash proceeds for the issuance of 53,637 shares and 713,030 pre-funded warrants. In June 2025, the Company completed a private placement equity raise that provided $3.9 million net cash proceeds for the issuance of 21,924 shares and 1,158,953 pre-funded warrants. However, the Company’s existing cash resources, the cash received from the equity offering, and financing available under the revolving note are not expected to provide sufficient funds to carry out the Company’s operations and clinical trials through the next twelve months.

The ability of the Company to continue as a going concern is dependent upon its ability to continue 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. These 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.

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 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.

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. In addition to monthly base rent, the Company pays monthly CAM fees, 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 AG真人官方 Estate (ARE-QRS-CORP) is the beneficiary of the LOC. The current LOC expires on March 1, 2026.

Note 4 – Notes Payable-Related Party

On October 14, 2024, as part of the senior convertible note offering described in Note 5, the Company entered into a loan with an officer of the Company in the amount of $250,000 (principal) with an interest rate of 14.5% per annum due October 13, 2025, and warrants to purchase 4,016 shares of common stock at an exercise price of $35.00 per share. As of June 30, 2025, there was outstanding principal and interest balances for these related party notes of $250,000 and $7,753, respectively. Under the fair value option, the senior convertible note is $127,689 as of June 30, 2025.

On September 4, 2024, the Company issued a $250,000 promissory note (the “Promissory Note”) to an officer of the Company for $250,000. The Promissory Note accrues interest at 12% per annum and is repayable in 12 substantially equal installments over a period of one year. During the three and six months ended June 30, 2025 the Company incurred $2,614 and $8,009 in interest expense relating to this Promissory Note. For the three and six months ended June 30, 2025, the Company repaid principal of $63,405 and $124,944, respectively. For the three and six months ended June 30, 2025, the Company paid interest of $3,232 and $8,329, respectively. The principal balance of the Promissory Note as of June 30, 2025 and December 31, 2024 was $65,326 and $190,270, respectively.

Note 5 - Convertible Notes and Loan Agreement

Revolving Note Agreement

On February 27, 2025, the Company entered into a Revolving Loan Agreement with a lender. Pursuant to the Revolving Loan Agreement, the Company issued a revolving note dated February 28, 2025 in the principal amount of up to $2,000,000 (the “Revolving Note”), which the Company may draw upon at its discretion from time to time through its maturity on February 28, 2026.

The Revolving Note bears interest at the rate of 18% per annum calculated on the basis of a 360-day year, consisting of twelve 30 calendar day periods, and shall accrue interest daily commencing from the date of any draw down until paid in full on the maturity date. The Company recognized deferred loan costs of approximately $78,000 in relation to the closing of the Revolving Loan Agreement as an asset on the unaudited condensed consolidated balance sheet. These deferred loan costs are being amortized to interest expense on a straight-line basis to the maturity of the Revolving Loan Agreement. During the three and six months ended June 30, 2025, the Company recognized $23,392 and $29,928 in interest expense related to the amortization of these deferred loan costs, respectively.

The Revolving Loan Agreement contains customary events of default. If an event of default occurs, the lender may accelerate the repayment of amounts outstanding under the Revolving Loan Agreement, and an amount equal to 120% of the outstanding principal amount and accrued and unpaid interest plus other amounts, costs, expenses and/or liquidated damages. The default provision meets the criteria of a derivative liability that would have an associated fair value if any amounts are outstanding under the Agreement.

As of June 30, 2025, the Company has not yet drawn on the Revolving Note and no balances are outstanding.

2024 Convertible Bridge Notes

During October 2024, the Company completed a senior convertible note offering in two closings, as further described below.

On October 14, 2024, the Company issued an aggregate of $600,000 (of an up to $1.3 million authorized financing) senior secured convertible notes due in October 2025, which accrue interest at 14.5% interest per year. The notes include a 5% original issue discount and the Company received $570,000 in proceeds. The notes are optionally convertible by each holder at a 10% premium beginning three months after the date of issuance, and the conversion price will be the 5-day volume-weighted average price (“VWAP”) immediately prior to closing unless re-set (one-time only) by a lower price of an offering entered into by the Company during the term of the notes. The Company has the option to prepay the notes at any time for 107% of total outstanding balance and any outstanding principal will be paid in conversion of shares of common stock at a 15% discount at the end of the term, subject to the Company’s exercise of the optional prepayment right. Any accrued interest will be repaid quarterly in cash. The Company also issued warrants to the lenders to purchase an aggregate 9,639 shares of common stock, exercisable at $35.00 per share, with such warrants expiring five years from issuance. In addition, the Company’s former Chief Executive Officer and Chief Scientific Officer, Dr. Anatoly Dritschilo, invested a total of $237,500 in this financing round, in exchange for a $250,000 convertible note.

As part of the same offering, on October 21, 2024, the Company issued an additional $231,579 in senior secured convertible notes due in October 2025, with substantially similar terms as the October 14, 2024, issuance. The notes include a 5% original issue discount and the Company received $220,000 in proceeds. The Company also issued warrants to the lenders to purchase an aggregate 3,543 shares of common stock, exercisable at $37.25 per share, with such warrants expiring five years from issuance. Upon completing this issuance, the Company closed the senior secured convertible note offering after receiving a total of $790,000 in proceeds.

After analyzing the terms of the senior convertible notes (“Convertible Bridge Notes”) and its embedded features, the Company elected to account for the Convertible Bridge Notes at fair value under the allowable fair value option election. As such, the Company initially recognized the Convertible Bridge Notes at their fair value and subsequently measures the notes at fair value with changes in fair value recorded in current period earnings (or other comprehensive income, if specific to Company credit risk). The Company initially recorded the Convertible Bridge Notes at their estimated issuance date fair value of $806,758. As the fair value of the Convertible Bridge Notes exceeded the proceeds received, the Company recorded a loss on issuance of convertible notes of $16,758. The proceeds were allocated in full to the Convertible Bridge Notes recorded at fair value. The warrants issued in connection with the Convertible Bridge Notes were deemed to be equity instruments. In addition, the Company allocated the issuance costs incurred to these instruments to the Convertible Bridge Notes and, as such, expensed $107,491 in issuance costs, including $41,579 of original issue discount on the Convertible Bridge Notes.

The Company used a Monte Carlo simulation model to calculate the fair value of the Convertible Bridge Notes. The Convertible Bridge Notes were classified within Level 3 of the fair value hierarchy at the initial measurement date, due to the use of unobservable inputs. The key inputs into the model for the Convertible Bridge Note were as follows:

Upon mandatory conversion of the current outstanding principal of the notes at their maturity, 117,084 shares of common stock would be issuable.

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 “Alto Warrant”) to purchase 5,091 shares of common stock, exercisable at $470.00 per share, for gross proceeds of $3,935,000 (the “Investment Amount”) (See Note 6). As a consequence of the Company issuing the Convertible Bridge Notes, and then subsequently completing the Equity Financings in March 2025 and June 2025, the exercise price of the Alto Warrant was adjusted to $3.38. The Company determined that the Alto Warrant contains a net cash settlement feature at inception and categorized the Alto Warrant as a liability in the accompanying unaudited condensed consolidated financial statements. The Alto Convertible Note was amortized on a monthly basis and the Company could make such monthly amortization payments in cash or, subject to certain equity conditions, in registered shares of common stock or a combination thereof. Installments could be deferred by the noteholder, resulting in a variable interest rate. However, the effective interest rate was approximately 346% 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 was convertible into shares of common stock at a price per share equal to the lower of (i) $470.00 per share, as adjusted, (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 had an acceleration of installment amount conversion option (the “Alto Acceleration Option”), whereby the noteholder, with certain share percentage limitations, could 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 determined the Alto Acceleration Option was an embedded derivative within the host instrument and 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 Alto Convertible Note was repayable over 26 months and bore interest at the rate of 5% per annum. Additionally, the note contained 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 defaulted 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 million in convertible notes and warrants on substantially the same terms as the Alto Convertible Note and Alto Warrant, excluding the Springing DACA requirement, with such option to be effective through December 31, 2025. The agreement offered the investor an opportunity to participate in future capital raises at substantially similar terms as the January 11, 2023 agreement. The Company expected 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 357 shares of common stock, exercisable at $470.00 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 of five 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 was being amortized to interest expense over the term of the Alto 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 was being amortized to interest expense over the term of the Alto Convertible Note.

On August 6, 2024, the Company entered into an amendment to the SPA with Alto. Under the Amendment Agreement, the Company and Alto agreed as follows: (i) that the Company would pay $600,000 (the “Cash Collateral”) in cash to Alto, which would be held as collateral on the remaining $1.2 million outstanding under the Alto Note; (ii) Alto will defer the monthly installment payment due on September 3, 2024 under the Alto Note until the Alto Note’s March 11, 2025 maturity date; and (iii) Alto would grant a waiver of any default Section 4(a)(xvi) of the Note related to the restatement and reaudit of the Company’s financial statements for the years ended December 31, 2022 and 2023. The amendment was accounted for as a troubled debt restructuring as the Company determined it was experiencing financial difficulties and was provided a concession through the deferral of one monthly principal and interest payment. As the future undiscounted cash flows exceeded the carrying value of the Alto Convertible Note, the Company did not recognize any gain or loss associated with the troubled debt restructuring.

On February 26, 2025, the Company, entered into an amendment agreement (the “Amendment Agreement”) for purposes of amending the terms of the SPA originally dated January 11, 2023, and as amended May 10, 2023, June 5, 2023 and August 6, 2024, between the Company and Alto.

Under the Amendment Agreement, in exchange for the Company’s payment of $75,000 to Alto, Alto agreed to permanently waive its right to purchase up to $10 million in Additional Notes and Additional Warrants and to a one-time waiver of the right to participate in the Company’s contemplated registered securities offering, as disclosed in the Company’s registration statement on Form S-1, filed with the SEC on February 13, 2025. The payment to Alto was accounted for as an issuance cost and recorded as a reduction to additional paid-in capital.

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 3,128 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.

Additionally, the March 2025 Pre-Funded Warrants included restrictions on exercise in the event the holder’s beneficial ownership of the Company’s common stock would exceed 4.99% of the number of shares of common stock outstanding immediately after giving effect to the exercise.

The Company concluded that the March 2025 Pre-Funded Warrants met the requirements to be classified in stockholders’ equity, and have been recorded as additional paid in capital.

As of June 30, 2025, all of the 713,030 March 2025 Pre-Funded Warrants have been exercised.

June 2025 Private Placement

On June 20, 2025, the Company entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) in a private placement, and engaged WestPark Capital, Inc. (“WestPark”) as the sole placement agent (the “Placement Agent”), pursuant to which the Company sold an aggregate of $4.3 million of its securities. The private placement consisted of the issuance of (i) 21,924 shares of common stock of the Company at a purchase price of $3.60 per share, and (ii) 1,158,953 pre-funded warrants, each to purchase one share of common stock of the Company at a purchase price of $3.599 and exercise price of $0.001 per pre-funded warrant (the “June 2025 Pre-Funded Warrants”) to one investor. The private placement closed on June 24, 2025. The private placement resulted in gross proceeds of approximately $4.3 million and net proceeds of approximately $3.9 million, reflecting approximately $0.4 million of placement agent fees, legal costs and other expenses connected with the transaction. The private placement closed on June 24, 2025.

The June 2025 Pre-Funded Warrants are exercisable at any time after issuance on June 24, 2025, at an exercise price of $0.001 per share.

In connection with the Securities Purchase Agreement, the Company entered into a registration rights agreement with the investor. Pursuant to the registration rights agreement, the Company agreed to file a registration statement with the Securities and Exchange Commission (the “SEC”) to register for resale the shares of common stock, and the shares issuable upon exercise of the pre-funded warrants issued under the purchase agreement, within 10 days of the closing date, and to have such registration statement declared effective within 90 days of the closing date (or 120 days if the registration statement is reviewed by the SEC). The registration rights agreement provided that the Company would be obligated to pay certain liquidated damages to the investor if the Company failed to file the resale registration statement, or to have such registration statement declared effective by such dates. The Company was prepared to file the registration statement within the deadline required under the registration rights agreement but due to requests by the investor, the Company did not file the registration statement until August 4, 2025 , upon receiving the investor’s request to do so. The registration statement was declared effective on August 11, 2025.

The warrants had intrinsic value of $1,960 as of June 30, 2025. All of the outstanding warrants are exercisable as of June 30, 2025.

Equity Incentive Plan

The Company’s 2018 Equity Incentive Plan (the “2018 Plan”) provides for equity incentives to be granted to 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 Plan, restricted stock awards, other stock-based awards, or any combination of the foregoing. The 2018 Plan is administered by the Company’s compensation committee. In May 2025, the Company increased the shares authorized under the 2018 Plan by 5,000,000 shares. As of June 30, 2025, the Company has authorized 8,000,000 shares of common stock for issuance under the 2018 Plan. As of June 30, 2025, 69,066 shares have been granted, net of forfeitures, under the 2018 Equity Incentive Plan, of which 37,624 shares have vested.

Restricted Stock Units

The Company 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 the 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, 2025, pursuant to agreements with directors, officers and consultants, 22,101 RSUs with a value of $0.3 million were granted. During the three and six months ended June 30, 2024, 1,139 and 2,139 RSUs, respectively, with a value of $0.1 million and $0.1 million, respectively, were granted.

On February 27, 2025, the Company entered into a Revolving Loan Agreement with Bowery Consulting Group Inc. (“Bowery”) where the Company may borrow from Bowery an aggregate principal amount of up to $2,000,000 (see Note 5). As part of one of the lender conditions, no less than four of the current board members were to resign, with three new nominees to be elected and appointed by the remaining members of the Company’s Board of Directors. Upon the resignation of the four board members, vesting of all outstanding unvested RSUs held by the departing board members were allowed to accelerate immediately. The Company concluded that the acceleration represented a modification of the outstanding unvested RSUs. As a result of the modification, the Company recorded approximately $0.5 million of stock-based compensation expense.

As of June 30, 2025, there was $0.5 million 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 2.48 years.

Note 7 – Derivative Liabilities

Fair Value Assumptions Used in Accounting for Derivative Liabilities

ASC 815 requires the Company 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 October 2024, in connection with the October 2024 Equity Financing, the Company issued warrants to purchase 118,033 shares of common stock, with an exercise price of $35.00 per share, valued at inception at $0.2 million and as of June 30, 2025, at less than $0.1 million. The Company determined that the derivative liabilities from the warrants issued in relation to the October 2024 Equity Financing did not qualify for classification as equity instruments as they did not meet the requirements to be considered indexed to the Company’s own stock, due to potential variability in the settlement amount upon a fundamental transaction, as defined.

In January 2023, in connection with the Alto Convertible Note, the Company issued warrants to purchase 5,091 shares of common stock, with an exercise price of $3.38 per share, as adjusted, valued at inception at $1.1 million and as of June 30, 2025, at less than $0.1 million. The Company determined that the derivative liabilities from the warrants issued in relation to the Alto Convertible Note did not qualify for classification as equity instruments due to the existence of certain net cash settlement provisions that are 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 in the Alto warrants 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 $1.4 million at inception, using a Monte Carlo simulation model. The Company determined its derivative liability from the noteholder’s Acceleration Option for the Alto Convertible Note was not clearly and closely related to the host and should thus be accounted for as a bifurcated derivative liability. As of June 30, 2025, the value of the Acceleration Option was $0 as the Alto Convertible Note was settled in full by September 30, 2024.

The Company classifies these derivative liabilities as a Level 3 fair value measurement and used the Monte Carlo pricing model to calculate the fair value as of June 30, 2025 (less than $0.1 million) and December 31, 2024 (less than $0.1 million).
