Current report
We do not undertake any obligation to update forward-looking statements to reflect events or circumstances occurring after the date of this report, except as required by U.S. federal securities laws.
Current report
On December 31, 2024, we received a letter from the Nasdaq Listing Qualifications Staff of The Nasdaq Stock Market LLC (“Nasdaq”) stating that for the 30 consecutive business day period between November 15, 2024 to December 30, 2024 our common stock had failed to maintain a minimum closing bid price of $1.00 per share, as required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), we have a period of 180 calendar days, or until June 30, 2025 (the “Compliance Period”), to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price of our common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days.
Current report
Because we have already completed a 1-for-8 reverse stock split in August 2024, under new Nasdaq rules, we will not be allowed an additional 180 day compliance period. As such, if we do not regain compliance with the Minimum Bid Price Requirement by June 30, 2025, we will be subject to delisting. As such, we are seeking stockholder approval to complete an additional reverse stock split at our upcoming Annual Meeting of Stockholders, scheduled to be held on May 9, 2025, in the event our stock does not begin trading above $1.00 per share in the interim.
Current report
If we cannot regain compliance during the Compliance Period, by reverse split or otherwise, Nasdaq will provide a notice that our common stock will be subject to delisting. At that time, we may appeal Nasdaq’s delisting determination to a Nasdaq Hearings Panel.
Current report
Nasdaq’s notice of noncompliance has no immediate effect on the listing of our common stock and our common stock will continue to be listed on The Nasdaq Capital Market under the symbol “SHPH.” There can be no assurance that we will regain compliance with the Minimum Bid Price Requirement or maintain compliance with any of the other Nasdaq continued listing requirements. We will continue to monitor the closing bid price of its common stock and may, if appropriate, consider available options to regain compliance with the Minimum Bid Price Requirement.
Current report
Following the Company’s March 2025 $5.75 million equity financing, on March 14, 2025, Nasdaq acknowledged that we had regained compliance with the Listing Rule 5550(b)(1) but indicated that if we fail to evidence compliance upon filing our next periodic report for the period ended March 31, 2025, we may be subject to delisting. As evidenced herein, we continue to be in compliance with the Listing Rule 5550(b)(1). However, Nasdaq will continue to monitor our ongoing compliance with the Minimum Equity Requirement and, subject to a determination that we are not in compliance, we may be subject to delisting.
Current report
*Other Income (expense).*During the three months ended March 31, 2025, other expense decreased by $0.3 million or 73% compared to the same period in 2024. The decrease was primarily driven by a $0.5 million decrease in interest expense. The decrease was partially offset by a $0.2 million decrease in change in fair value of derivative liabilities.
Current report
In January 2025, we entered into a change order to the existing agreement with Theradex Systems, Inc., our primary third-party CRO, for purposes of supporting our clinical trials of Ropidoxuridine. Following the change order, our total cost limit increased by $3.0 million, for an aggregate of $5.3 million, of which $2.4 million had not yet been incurred as of March 31, 2025.
Current report
In March 2025, we entered into a consulting services agreement (the “Bowery Consulting Agreement”) with Bowery Consulting Group Inc. (the “Consultant”). According to the Bowery Consulting Agreement, the Consultant will provide consulting services in connection with our business, advising on viability of plans for scaling activities, growth and capital raising strategies and cost minimization associated with technological platform improvements and marketing spend. We agreed to pay the Consultant $260,000 for their services. We are not obligated to pay amounts under the Bowery Consulting Agreement until we regain full Nasdaq listing requirement compliance.
Current report
In April 2025, we entered into a consulting agreement (the “IR Agency Consulting Agreement”) with IR Agency LLC (the “IR Agency”). Pursuant to the IR Agency Consulting Agreement, IR Agency agrees to provide certain marketing and advertising services to communicate information about us to the financial community (the “Services”), including, but not limited to, creating company profiles, media distribution and building a digital community with respect to us.

Current report
On February 27, 2025, we entered into a Revolving Loan Agreement (the “Revolving Loan Agreement”) with certain lender identified on the signature page thereto. Pursuant to and under the terms of the Revolving Loan Agreement, we issued a revolving note dated February 28, 2025 in the principal amount of up to $2.0 million (the “Revolving Note”), which we may draw upon at our 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.
Current report
On March 12, 2025, we consummated a public offering of an aggregate of (i) 1,340,921 shares of common stock, of the Company, at a public offering price of $0.30 per share and (ii) pre-funded warrants to purchase 17,825,746 shares of common stock at an exercise price of $0.001 per share, at a public offering price of $0.299 per pre-funded warrant (the “Offering”). The Offering closed on March 13, 2025. We received gross proceeds of approximately $5.7 million and net proceeds of approximately $5.0 million, reflecting approximately $0.7 million of legal costs and other expenses connected with the Offering.
Current report
In addition, we continued progress on our R&D programs during the three months ended March 31, 2025 that resulted in increased cash expenditures. The Company’s current liabilities as of March 31, 2025 are primarily comprised of $0.7 million of convertible notes payable, $0.9 million of accounts payable and accrued expenses, $0.1 million of notes payable to related parties, and the current portion of our operating lease liability of $0.1 million. The increase in current liabilities is primarily due to an increases in accounts payable and accrued expenses of $0.2 million, primarily attributable to our efforts to preserve cash while we strive to raise funds to finance ongoing business and operations.
Current report
Cash Flows
Current report
Our cash flows from operating activities are greatly influenced by our use of cash for operating expenses and working capital requirements to support the business. We have historically experienced negative cash flows from operating activities as we invested in research and development activities. The cash used in operating activities resulted primarily from our net losses adjusted for non-cash charges, which are generally attributable to stock-based compensation, changes in fair value of our derivative liabilities and amortization of debt discounts and finance fees, as well as changes in components of operating assets and liabilities, which are generally attributable to increased expenses and timing of vendor payments.
Current report
During the three months ended March 31, 2025, net cash used in operating activities of $2.5 million was primarily due to our net loss of $3.0 million, stock-based compensation of $0.5 million, change in fair value of convertible notes of $0.1 million, partially offset by the net change in operating assets and liabilities of $0.1 million.
Current report
During the three months ended March 31, 2024, net cash used in operating activities of $1.2 million was primarily due to our net loss of $1.7 million, increased by a gain on change in derivative liabilities of $0.2 million, offset by amortization of debt discount of $0.4 million, loss on settlement of convertible debt of less than $0.1 million, accrued interest settled with common stock of less than $0.1 million, stock-based compensation of $0.1 million and increased by a net change in working capital of $0.1 million.
Current report
For the three months ended March 31, 2025, the Company did not have investing activities. For the three months ended March 31, 2024, cash flows used in investing activities was primarily attributable to investing in trading marketable securities for $19 thousand and receiving $120 thousand in proceeds from disposition of marketable securities.
Current report
For the three months ended March 31, 2025, cash flows from financing activities was primarily comprised of net proceeds of $5.4 million, from the sale of common stock and pre-funded warrants, net of placement agent costs of $0.3 million, partially offset by $0.2 million payment of other issuance costs for issuance of common stock and equity-classified warrants, $0.1 million of payment for finance cost, and $0.1 million of repayment of note payable-related party used to finance the Company’s ongoing operations. For the three months ended March 31, 2024, the Company paid $40,000 related to financing activities.

Fair Value of Convertible Notes
Current report
As permitted under ASC 825, Financial Instruments (“ASC 825”), we elected the fair value option to account for the October 2024 Convertible Bridge Notes. The valuation of the October 2024 Convertible Bridge Notes utilizes a Monte Carlo simulation model. Monte Carlo simulation models require the use of simulations that are weighted based on projected future stock prices, the volatility of a set of guideline companies and significant unobservable inputs including probabilities assigned to not achieving a successful capital raise and a registration of related securities. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average.
Current report
The significant inputs and assumptions used to estimate the fair value also include: (i) the expected timing of conversion, (ii) the amount subject to equity conversion, (iii) the sum of the notes’ principal and unpaid accrued interest, (iv) expected volatility, (v) risk-free interest rate, (vi) the discount rate, (vii) volume-weighted average price (“VWAP”), (viii) illiquidity discounts, and (ix) probabilities assigned. The October 2024 Convertible Bridge Notes are subject to revaluation at the end of each reporting period, with changes in fair value recognized in the accompanying unaudited condensed consolidated statements of operations, or for changes due to our credit worthiness, if any, as a component of other comprehensive income.
Current report
Fair Value of Warrants to Purchase Common Stock
Current report
We have issued warrants to investors in our debt and equity offerings. We have also issued warrants to service providers in relation to our financing offerings.
Current report
We evaluate all warrants issued to determine the appropriate classification under ASC 480 and ASC 815 (as well as under ASC 718 for warrants issued as share-based payments). In addition to determining classification, we evaluate these instruments to determine if such instruments meet the definition of a derivative.
Current report
For warrants that are determined to be equity-classified, we estimate the fair value at issuance and record the amounts to additional paid in capital (potentially on a relative fair value basis if issued in a basket transaction with other financial instruments). Warrants that are equity-classified are not subsequently remeasured unless modified or required to be reclassified as liabilities. For warrants that are determined to be liability-classified, we estimate the fair value at issuance and each subsequent reporting date, with changes in the fair value reported in the unaudited condensed consolidated statements of operations. The classification of all outstanding warrants, including whether such instruments should be recorded as equity, is evaluated at the end of each reporting period.
Current report
For warrants with uncertain or more complex terms (such as variability in the warrant shares or exercise price), we may utilize more complex models to address such provisions, including Monte Carlo simulation models. Monte Carlo simulation models require the use of simulations that are weighted based on projected future stock prices, the volatility of a set of guideline companies and significant unobservable inputs including probabilities assigned. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average.

Reverse Stock Split
Previous report
On August 13, 2024, in order to meet the Nasdaq 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. All share, option, warrant and per share amounts (except our authorized outstanding and previously reserved shares) have been retroactively recast in our most recent filings, and are presented as such in these financial statements and related disclosures.
Previous report
This Notification has no immediate effect on the listing of the Company’s securities on the Nasdaq Capital Market. Nasdaq has provided the Company with 45 calendar days, or until October 25, 2024, to submit a plan to regain compliance with the minimum stockholders’ equity standard. If the Company’s plan to regain compliance is accepted, Nasdaq may grant an extension of up to 180 calendar days from September 10, 2024 for the Company to regain compliance.
Previous report
On October 15, 2024, the Company submitted a plan to Nasdaq to regain compliance. However, there can be no assurance that the Company’s plan will be accepted or that, if it is, that the Company will be able to regain compliance and maintain its listing on the Nasdaq Capital Market. If the Company’s plan to regain compliance is not accepted or if Nasdaq does not grant an extension and the Company does not regain compliance, or if the Company fails to satisfy another Nasdaq requirement for continued listing, Nasdaq could provide notice that the Company’s securities will become subject to delisting. In that event, the Company will have an opportunity to appeal Nasdaq’s decision to a hearings panel.

The $0.4 million gain in fair value of derivative liability resulted from the fair value measurement using the Monte Carlo pricing model and the impact of the decrease in the market price of warrant shares. These amounts were largely attributable to the Alto Convertible Note conversions and cash management activities.

Founded by Georgetown University Medical School faculty members, Shuttle Pharmaceuticals Holdings, Inc. (the “Company”) is a discovery and development stage pharmaceutical company leveraging our proprietary technology to develop novel therapies that are designed to cure cancer. Originally formed as Shuttle Pharmaceuticals, LLC in 2012, our goal is to extend the benefits of cancer treatments by leveraging insights into cancer therapy with surgery, radiation therapy, chemotherapy and immunotherapy. While there are several therapies being developed with the goal of curing cancer, one of the most effective and proven approaches to this is radiation therapy (RT). We are developing a pipeline of products designed to address the limitations of the current standard of cancer therapies. We believe that our product candidates will enable us to deliver cancer treatments that are safer, more reliable and at a greater scale than that of the current standard of care.

Operations to date have focused on continuing our research and development efforts to advance Ropidoxuridine clinical testing and improved drug formulation, to advance HDAC6 inhibitor (SP-2-225) preclinical development and explore new Small Business Innovation Research (SBIR) contract work on predictive biomarkers of radiation response, as well as prostate cell lines for health disparities research. We received SBIR contract funding from the National Institutes of Health (NIH), for the aforementioned projects. The clinical development of Ropidoxuridine has shown drug bioavailability and a maximum tolerated dose has been established for use in Phase II clinical trials. TCG GreenChem, Inc. (“TCG GreenChem”), with whom we have contracted for process research, development and cGMP compliant manufacture of IPdR, has successfully completed the manufacturing campaign for the active pharmaceutical ingredient (API) of Ropidoxuridine for use in the Company’s upcoming Phase II clinical trial in brain cancer patients undergoing radiation therapy. Shuttle also worked with University of Iowa Pharmaceuticals to develop the formulation, produce the capsules, and which have been shipped to Contract Research Organization (CRO) Theradex Oncology for distribution to clinical trial sites. Both activities have now been completed. In addition, Shuttle received approval from the U.S. Food and Drug Administration (FDA) to begin the clinical trial. The FDA made recommendations to expand the clinical trial and the Company agreed with the recommendation. With this change incorporated into the revised protocol, the Company commenced its Phase II clinical study with finalized agreements with all six of the planned site enrollment locations to administer the Phase II clinical trial of Ropidoxuridine and has enrolled the first three patients in October 2024. The radiation biomarker project and the health disparities project have been completed and the Company is following up with plans for clinical validation and potential commercialization. Changes in operational, administrative, legal and professional expenses related to our operations are set forth in more detail in the discussion below.

Operations to date have focused on continuing our research and development efforts to advance Ropidoxuridine clinical testing and improved drug formulation, to advance HDAC6 inhibitor (SP-2-225) preclinical development and explore the application of the PC-RAD Test, predictive biomarkers of radiation response. The clinical development of Ropidoxuridine has included completion of a Phase I clinical trial to establish drug bioavailability and a maximum tolerated dose for use in Phase II clinical trials. TCG GreenChem, with whom we have contracted for process research, development andcGMP compliant manufacture of IPdR, has manufactured the API of Ropidoxuridine and the University of Iowa Pharmaceuticals has formulated the drug product for use in our upcoming Phase II clinical trial in brain cancer patients undergoing radiation therapy. The drug product (capsules) were shipped to CRO Theradex Oncology and distributed to clinical trial sites that are fully approved to enroll patients in the trial. Shuttle received approval from the FDA to begin the clinical trial. The FDA thereafter made recommendations to expand the clinical trial to include a randomized dose “optimization” step and we agreed with the recommendation. Meetings with engaged clinical sites to review the protocol documents have occurred and FDA required IRB approvals have been received. With FDA recommended changes incorporated into the revised protocol and the completion of site initiation visits, we commenced our Phase II clinical study in October 2024. The Company’s radiation biomarker project and the health disparities project have been completed and we are proceeding with plans for clinical validation and potential for commercialization of Ropidoxuridine as a radiation sensitizer.

Previous wording
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 $7.5 million and no revenues for the nine months ended September 30, 2024 and has a working capital deficit of approximately $1.3 million as of September 30, 2024. The Company does not expect to generate positive cash flows from operating activities in the near future.
Current wording
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. We have incurred losses since inception and had a net loss of $3.0 million and no revenues generated during the three months ended March 31, 2025 and working capital of approximately $3.2 million as of March 31, 2025. We do not expect to generate positive cash flows from operating activities in the near future.
Previous wording
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.

As of December 31, 2023, total current assets were $5.6 million and total current liabilities were $1.0 million, resulting in a working capital of $4.6 million. As of September 30, 2024, the current assets were from $0.2 million cash, $0.1 million in prepaid expenses and $0.1 million in deferred costs, with the decrease from December 31, 2023 being primarily due to ongoing cash burn from our R&D programs, filing expenses, reaudits, and general operations. The increase in current liabilities is primarily due to an increase in accounts payable of $1.1 million compared to December 31, 2023, partially offset by the net change in amounts owed under convertible notes and notes payable of $0.5 million.

This discussion and analysis of our financial condition and results of operations is based on our unaudited condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. While our significant accounting policies are described in more detail in the notes to our unaudited condensed consolidated financial statements included elsewhere in this report, we believe that the following accounting policies are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Previous wording
The use of Black Scholes valuation model requires the input of highly subjective assumptions, including the expected price volatility, that is based on an analysis of the historical volatility of the common stock of a group of comparable entities. Any change to these inputs could produce significantly higher or lower fair value measurements.

Previous wording
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. The classification of derivative instruments, including whether such instruments should be recorded as liabilities are evaluated at the end of each reporting period.
Current wording
We evaluate our financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, such as the Acceleration Option in the Alto warrants (as defined in Note 5). 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. The classification of derivative instruments, including whether such instruments should be recorded as liabilities are evaluated at the end of each reporting period.
Previous wording
For our derivative financial instruments classified as a liability, the Company uses a Monte Carlo valuation model to value the derivative instruments at inception and on subsequent valuation dates. The model requires the use of simulations that are weighted based on significant unobservable inputs including the average volatility of a population set and probabilities assigned. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average. The Monte Carlo simulation uses an implied VWAP for valuation. The implied VWAP was backsolved by setting the summation of the parts (e.g., derivatives and debt without derivatives) equal to the cash proceeds and is updated each period.
