**FORWARD LOOKING STATEMENTS**

This Annual Report on Form 10-K (including the section regarding Management's Discussion and Analysis of Results of Operations, the "Annual Report") contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. These statements are based on our management's beliefs and assumptions and on information currently available to our management. Although we believe that the expectations reflected in these forward-looking statements are reasonable, these statements relate to future events or our future financial performance, and involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. All statements other than statements of historical facts contained in this Annual Report are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as "may," "could," "will," "would," "should," "expect," "plan," "anticipate," "believe," "estimate," "intend," "predict," "seek," "contemplate," "project," "continue," "potential," "ongoing" or the negative of these terms or other comparable terminology. These forward-looking statements include, but are not limited to, statements about:

● the implementation of our business model and strategic plans for our business, technologies and product candidates;

● our estimates of our expenses, ongoing losses, future revenue and capital requirements;

● our ability to obtain additional funds for our operations;

● our ability to obtain and maintain intellectual property protection for our technologies and product candidates and our ability to operate our business without infringing the intellectual property rights of others;

● our ability to attract and retain qualified key management and technical personnel;

● our use of net proceeds received by us from our ongoing fundraising efforts, whether from public offerings or private placements of securities;

● our expectations regarding the time during which we will be an emerging growth company under the JOBS Act;

● our financial performance; and

● developments relating to our competitors or our industry.

You should not place undue reliance on forward-looking statements, because they involve known and unknown risks, uncertainties, and other factors, which are, in some cases, beyond our control and which could materially affect results. Factors that may cause actual results to differ materially from current expectations include, among other things, those listed in the section titled "Risk Factors" in this Annual Report, and in our other filings with the Securities and Exchange Commission (the "SEC"). Actual events or results may vary significantly from those implied or projected by the forward-looking statements due to these risk factors. No forward-looking statement is a guarantee of future performance. You should read this Annual Report, the documents that we reference in this Annual Report and the documentation we have filed as exhibits thereto with the SEC, with the understanding that our actual future results and circumstances may be materially different from what we expect.

Unless the context otherwise requires, the terms "the Company," "Shuttle Pharma," "we," "us," and "our" in this Annual Report refer to Shuttle Pharmaceuticals Holdings, Inc. and its subsidiaries.

**Summary Risk Factors**

The risks described under the heading "Risk Factors" beginning on page 8 of this Annual Report may cause us not to realize the full benefits of our strengths and/or may cause us to be unable to successfully execute all or part of our strategy. Some of the more significant challenges we face include:

● Our
 ability to continue as a going concern in the near term is dependent upon us successfully raising additional equity or debt financing
 to fund our operations.

● Recent
 and future acquisitions may have a material adverse effect on our ability to manage our business and our results of operations and
 financial condition.

● If
 we are unable to acquire and retain customers for our Molecule.ai platform or if any of such customers renew licenses at lower prices,
 our future revenues may be negatively impacted.

● While
 our Company's management is working to improve our internal controls and procedures, at present management has determined that
 our internal controls were deemed to be inadequate, which could cause our financial reporting to be unreliable and lead to misinformation
 being disseminated to the public.

● If
 we fail to comply with the continued listing requirements of The Nasdaq Stock Market, it could result in our common stock being delisted,
 which could adversely affect the market price and liquidity of our securities and could have other adverse effects.

● Our
 ability to satisfy the continued listing requirements of the Nasdaq Capital Market and maintain the listing of our common
 stock.

● Our
 stock price may be volatile, and purchasers of our common stock could incur substantial losses.

● The
 future issuance of equity or of debt securities that are convertible into common stock will dilute our share capital.

● If
 securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading
 opinion regarding our stock, our stock price and trading volume could decline.

● Our
 board of directors has the authority, without stockholder approval, to issue preferred stock with terms that may not be beneficial
 to holders of our common stock and such issuance could potentially adversely affect stockholders' voting power and perpetuate
 their control over us.

**PART I**

**Item 1. Business**

On November 21, 2025, we acquired substantially all of the assets and liabilities of Molecule.ai, a pharmaceutical software company building an artificial intelligence ("AI") driven platform for molecular discovery and early-stage drug development. By combining modern AI techniques with structured scientific workflows, the Molecule.ai platform (hereafter, "Molecule.ai" or the "platform") helps researchers explore the chemical space more efficiently, evaluate molecular ideas with greater clarity and make more informed decisions during the earliest stages of drug development. The platform is engineered to accelerate the iteration cycles that characterize modern drug discovery while preserving scientific reproducibility, traceability and operational reliability. Molecule.ai adapts state of the art AI algorithms to create a practical, domain-specific AI infrastructure layer for molecular research and development. We will seek to leverage Molecule.ai's molecular modeling and predictive analytics platform to significantly augment our drug discovery and development business purpose. In tandem with the Molecule.ai asset acquisition, on November 20, 2025, we committed to a plan to wind-down our clinical trials of Ropidoxuridine (the "Clinical Trials"), our lead product candidate.

Molecule.ai is built on three core architectural components: a unified inference engine, an API-first integration layer and a modular model framework. The unified inference engine orchestrates model execution and multi-step reasoning through a deterministic and traceable sequence of operations. Molecule.ai uses an API-first design, which means that all platform capabilities can be accessed programmatically. All predictive and reasoning functions are modular, which allows the platform to expand over time without changing the underlying infrastructure. Molecule.ai currently supports three scientific and computational functions that reflect both its pharmaceutical focus and the structured inference techniques seen in modern agentic Large Language Model ("LLM") systems: (1) molecular property prediction, (2) cross-molecule and cross-property evaluation and (3) prediction reasoning and structured molecular insights. The platform predicts a wide range of molecular properties that are relevant to early-stage discovery and medicinal chemistry and provides inference pipelines for predicting molecular properties. By using transformer-based models, the platform computes predictive outputs on a wide range of therapeutic tasks. The platform evaluates multiple molecules across multiple properties in a unified workflow, helping researchers quickly identify the most-promising candidates, understand trade-offs, and make structured, evidence-based decisions. Molecule.ai also includes a reasoning module that uses LLM-based structured inference to contextualize predictions, explain differences between compounds, perform rule-guided reasoning and produce narrative or structured scientific interpretations with the goal to make complex scientific outputs understandable and actionable for broader research and development audiences.

The broader competitive landscape in the AI ecosystem, especially AI-driven drug discovery, is rapidly advancing toward agentic AI systems and more integrated, end-to-end platforms. To stay at the front of this shift, Molecule.ai is expanding its molecule predictive capabilities, and automated multi-tool workflows. These expansions are designed in accordance with the agentic framework and multi-tool reasoning to further strengthen the platform. A new module will evaluate chemical–protein interaction likelihoods, which will help researchers estimate how molecules may interact with specific biological targets. Molecule.ai is adding biological context reasoning supported by curated genomic and disease-association evidence, which helps tie together chemical ideas with the biological systems they may ultimately affect. The platform will increasingly support insights that connect chemical properties with biological implications, which creates a more complete, end-to-end picture for early research teams. Molecule.ai is also developing an autonomous AI agent designed to reduce manual workload and accelerate early research cycles, which will interpret a discovery objective, plan a series of actions, route each step to the appropriate tools, evaluate preliminary outputs and iterate until a stable result is achieved.

The Molecule.ai platform adheres to strict engineering standards, including reproducibility, traceability, extensibility, scalability and interoperability, which align with modern AI infrastructure expectations for regulated biomedical environments. Molecule.ai aims to become the foundational AI layer for molecular and biological reasoning in pharmaceutical research and development. By integrating property prediction, biological context, multi-step reasoning and agentic automation, the platform seeks to accelerate early discovery while maintaining scientific reliability and operational transparency.

We are still evaluating additional business impacts from the discontinuance of the Clinical Trials and the acquisition of Molecule.ai, all of which could materially affect our plans and financial position.

**Corporate Information**

The Company was formed as a limited liability company in the state of Maryland in December 2012 and was converted to a C corporation in August 2016. In June 2018, we completed a share exchange with Shuttle Pharma Acquisition Corp. Inc. ("Acquisition Corp."), pursuant to which Shuttle Pharmaceuticals, Inc. became a subsidiary of Acquisition Corp. and we subsequently changed the name of Acquisition Corp. to Shuttle Pharmaceuticals Holdings, Inc.

**Intellectual Property**

We have invested significant amounts of funds in research and development of Ropidoxuridine. Our research and development expenses before contract reimbursements related to Ropidoxuridine were $4,054,831 and $3,618,796 for the fiscal years ended December 31, 2025 and 2024 respectively, without receiving any reimbursements.

We are seeking multifaceted protection for our intellectual property that includes licenses, confidentiality and non-disclosure agreements, copyrights, patents, trademarks and common law rights, such as trade secrets. We enter into confidentiality and proprietary rights agreements with our employees, consultants, collaborators, subcontractors and other third parties and generally control access to our documentation and proprietary information.

On November 20, 2025, the Company committed to a plan to wind-down its clinical trials of Ropidoxuridine (the "Clinical Trials"), our lead product candidate.

**Employees**

As of the date of this Annual Report, we have two full-time employees. We consider our relationship with our employees to be good.

**Nasdaq Deficiency and Reverse Stock Splits**

Our common stock currently is listed for quotation on the Nasdaq Capital Market (the "Nasdaq"). We are required to meet Nasdaq listing rules in order to maintain such listing, including a requirement that the Company maintain stockholders' equity of at least $2.5 million. On September 10, 2024, we received a letter from the Nasdaq Listing Qualifications Staff (the "Nasdaq Staff") of The Nasdaq Stock Market LLC ("Nasdaq") notifying the Company that it is no longer in compliance with the minimum stockholders' equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires listed companies to maintain stockholders' equity of at least $2.5 million. Our plan to regain compliance was accepted by Nasdaq and we were granted an extra 180-days, or until March 10, 2025, to regain compliance.

On December 31, 2024, the Company received a letter from Nasdaq Staff stating that for the 30 consecutive business day period between November 15, 2024 to December 30, 2024 the Company's 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), the Company had a period of 180 calendar days, or until June 30, 2025, to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price of the Company's common stock must have met or exceed $1.00 per share for a minimum of 10 consecutive trading days.

Following the 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 failed to evidence compliance upon filing the March 31, 2025 Form 10-Q, we may have been be subject to delisting.

On June 16, 2025, in order to maintain the Minimum Bid Price Requirement, we effectuated a 1-for-25 reverse stock split of our issued and outstanding common stock, rounding up to account for any fractional shares. The reverse stock split had no effect on our authorized shares of common stock or preferred stock and the par value will remain unchanged at $0.00001, respectively. All common stock share, option, warrant and per share amounts (except our authorized but unissued shares and previously reserved shares) have been retroactively adjusted in these unaudited condensed consolidated financial statements and related disclosures. We evidenced compliance through maintaining a minimum closing bid price of our common stock of $1.00 per share or greater from June 16, 2025 to July 1, 2025. Accordingly, we regained compliance with Listing Rule 5550(a)(2).

On July 2, 2025, we received notification from Nasdaq acknowledging that we maintained the requisite minimum closing bid price of our common stock of $1.00 per share or greater. Accordingly, we regained compliance with Listing Rule 5550(a)(2), and the matter was closed.

For the year ended December 31, 2025, we reported stockholders' equity of $2,254,446, and, as a result, were not in compliance with the Stockholders' Equity Requirement. We believe, as of March 9, 2026, we regained compliance with the Stockholders' Equity Requirement based upon our underwritten public offering of 2,238,800 shares of our common stock at a public offering price of $0.50 per share, resulting in gross proceeds of $3,500,000 and net proceeds of approximately $3,360,000 after deducting underwriting discounts, commissions, and estimated offering expenses of $140,000. The offering included 4,761,000 pre-funded warrants at a price of $0.499 per warrant, each exercisable for one share of common stock at a nominal exercise price of $0.001 per share.

**Implications of Being an Emerging Growth and Smaller Reporting Company**

We qualify as an "emerging growth company" as defined in the JOBS Act. An emerging growth company may take advantage of relief from certain reporting requirements and other burdens that are otherwise applicable generally to public companies. These provisions include:

● reduced obligations with respect to financial data;

● an exception from compliance with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act");

● reduced disclosure about our executive compensation arrangements in our periodic reports, proxy statements and registration statements; and

● exemptions from the requirements of holding non-binding advisory votes on executive compensation or golden parachute arrangements.

We may take advantage of these provisions for up to five years or such earlier time that we no longer qualify as an emerging growth company. We would cease to be an emerging growth company upon the earliest of:

● the last day of the fiscal year on which we have $1.235 billion or more in annual revenue,

● the date on which we become a "large accelerated filer" (i.e., as of our fiscal year end, the total market value of our common equity securities held by non-affiliates is $700 million or more as of June 30),

● the date on which we issue more than $1.0 billion of non-convertible debt over a three-year period, or

● the last day of our fiscal year following the fifth anniversary of the date of the completion of our IPO.

We may choose to take advantage of some but not all of these reduced reporting burdens.

In addition, under the JOBS Act, emerging growth companies can take advantage of an extended transition period and delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for private companies. If we were to subsequently elect instead to comply with public company effective dates, such election would be irrevocable pursuant to the JOBS Act.

Also, we are a "smaller reporting company" and may continue to qualify as such even after we no longer qualify as an emerging growth company. For as long as we qualify as a "smaller reporting company," we may provide reduced disclosure in the public filings that we make with the SEC than larger public companies, such as the inclusion of only two years of audited financial statements and only two years of management's discussion and analysis of financial condition and results of operations disclosure.

As a result of qualifying as an emerging growth company and a smaller reporting company, to the extent we take advantage of the allowable reduced reporting burdens, the information that we provide to our stockholders may be different than what you might receive from other public reporting companies in which you hold equity interests.

**Item 1A. Risk Factors**

*An investment in our common stock involves a high degree of risk. You should carefully consider the following risk factors and all the other information in this Annual Report before you decide to buy our common stock. If any of the following risks actually occur, our business, financial condition, operating results, and prospects would be adversely affected, and you may lose all or part of your investment.*

**Risks Related to Our Business, Financial Condition and Capital Requirements**

***Our 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; our ability to continue as a going concern is dependent upon our ability to raise additional equity or debt financing to fund our operations.***

Our 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 $11.7 million and no revenues for the year ended December 31, 2025, with working capital deficit of approximately $7.5 million as of December 31, 2025. 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 consolidated financial statements are issued.

***Recent and future acquisitions may have a material adverse effect on our ability to manage our business and our results of operations and financial condition.***

We may acquire assets, businesses, technologies, services, or products which are complementary to our operations. Recent and future acquisitions, including the now completed asset acquisition of Molecule.ai pursuant to that certain Asset Purchase Agreement with 1563868 B.C. Ltd., a Canadian limited corporation, and the Company's wholly owned subsidiary, 1542770 BC Ltd., a Canadian limited corporation, and the related employment contract with Zhitian (Andy) Zhang, an individual residing in Vancouver, Canada (the "Asset Purchase"), may expose us to potential risks, including risks associated with our inability to realize the intended benefits of the Asset Purchase, the costs and expenses incurred in connection with such acquisitions, or the potential loss of or harm to relationships with future suppliers, employees, and potential customers resulting from our integration of a new asset class. If any of these risks were to occur, our operations could be materially and adversely affected.

***If we are unable to acquire and retain customers for our Molecule.ai platform or if any of such customers renew licenses at lower prices, our future revenues may be negatively impacted.***

Currently, we do not have any customers for our Molecule.ai platform. We expect to derive a significant portion of our revenues from future license agreements with new customers related to our Molecule.ai platform. As a result, acquiring new customers and maintaining the renewal rate of those new customers is critical to our future operating results. Factors that may affect the acquisition of new customers and renewal rates for future customers include:

● the price, performance, and functionality of our platform;

● the availability, price, performance, and functionality of competing software solutions;

● the success of competitive products or technologies;

● the stability, performance, and security of our technological infrastructure; and

● the business environment of our future customers.

If we fail to acquire customers, and once acquired, if we are unable to successfully renew agreements with such clients or if clients renew such agreements upon less favorable terms or at lower fee levels, our future revenues may be negatively impacted.

***While our Company's management is working to improve our internal controls and procedures, at present management has determined that our internal controls were deemed to be inadequate, which could cause our financial reporting to be unreliable and lead to misinformation being disseminated to the public.***

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. As defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), internal control over financial reporting is a process designed by, or under the supervision of, the principal executive and principal financial officer and effected by the board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

● pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

● provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and/or directors of the Company; and

● provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

We are required to include in our Annual Report on Form 10-K a report of management on the effectiveness of our internal control over financial reporting. We expect to incur additional expenses and diversion of management's time as a result of performing the system and process evaluation, testing and remediation required in order to comply with the management certification requirements.

Presently, we have identified financial reporting internal control weaknesses relating to segregation of duties, information technology general controls and various accounting processes. While we have improved our organizational capabilities, we still may not have a sufficient number of employees to segregate responsibilities and may be unable to afford further enhancements to our staff or engaging outside consultants or professionals further to fully mitigate these internal control deficiencies. During the course of our testing, we may identify other deficiencies that we may not be able to timely remediate. If we cannot provide reliable financial reports or prevent fraud, our business and operating results could be harmed, investors could lose confidence in our reported financial information, and the trading price of our common stock, if a market ever develops, could drop significantly.

***Failure of our information technology systems could significantly disrupt the operation of our business.***

Our business increasingly depends on the use of information technologies, which means that certain key areas such as research and development and sales are to a large extent dependent on our information systems or those of third-party providers. Our ability to execute our business plan and to comply with regulatory requirements with respect to data control and data integrity, depends, in part, on the continued and uninterrupted performance of our information technology systems, or IT systems and the IT systems supplied by third-party service providers. These systems are vulnerable to damage from a variety of sources, including telecommunications or network failures, malicious human acts and natural disasters. Moreover, despite network security and backup measures, some of our servers are potentially vulnerable to physical or electronic break-ins, computer viruses and similar disruptive problems. Despite the precautionary measures we and our third-party service providers have taken to prevent unanticipated problems that could affect our IT systems, sustained or repeated system failures or problems arising during the upgrade of any of our IT systems that interrupt our ability to generate and maintain data, and in particular to operate our proprietary technology platform, could adversely affect our ability to operate our business.

**Risks Related to our Common Stock**

***If we fail to comply with the continued listing requirements of The Nasdaq Stock Market, it could result in our common stock being delisted, which could adversely affect the market price and liquidity of our securities and could have other adverse effects.***

On December 31, 2024, the Company received a letter from Nasdaq stating that for the 30 consecutive business day period between November 15, 2024 to December 30, 2024 the Company's common stock had failed to maintain a Minimum Bid Price Requirement of $1.00 per share, as required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2).

In addition, on September 10, 2024, the Company received a letter from Nasdaq, notifying the Company that it was no longer in compliance with the Stockholders' Equity Requirement In the Company's Quarterly Report on Form 10-Q for the period ended June 30, 2024, the Company reported stockholders' equity of $801,434, which is below the minimum stockholders' equity required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1).

On October 15, 2024, the Company submitted a plan to Nasdaq to regain compliance, which was accepted by Nasdaq. As a result, the Company had until March 10, 2025 to complete a follow on equity raise to bring the Company's stockholders' equity above the minimum requirement of $2.5 million.

Following the 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 failed to evidence compliance upon filing the March 31, 2025 Form 10-Q, we may have been subject to delisting.

On June 16, 2025, in order to maintain the Minimum Bid Price Requirement, we effectuated a 1-for-25 reverse stock split of our issued and outstanding common stock, rounding up to account for any fractional shares. The reverse stock split had no effect on our authorized shares of common stock or preferred stock and the par value will remain unchanged at $0.00001, respectively. All common stock share, option, warrant and per share amounts (except our authorized but unissued shares and previously reserved shares) have been retroactively adjusted in these consolidated financial statements and related disclosures. We evidenced compliance through maintaining a minimum closing bid price of our common stock of $1.00 per share or greater from June 16, 2025 to July 1, 2025. Accordingly, we regained compliance with Listing Rule 5550(a)(2).

On July 2, 2025, we received notification from Nasdaq acknowledging that we maintained the requisite minimum closing bid price of our common stock of $1.00 per share or greater. Accordingly, we regained compliance with Listing Rule 5550(a)(2), and the matter was closed.

We reported stockholders' equity of $1,394,161 in our Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2025, and, as a result, were not in compliance with the Stockholders' Equity Requirement. We believe as of November 17, 2025, we regained compliance with the Stockholders' Equity Requirement based upon our private placement consummated on November 4, 2025, pursuant to which we raised aggregate gross proceeds of approximately $2.5 million, before deducting placement agent fees and offering expenses payable by us.

For the year ended December 31, 2025, we report herein stockholders' equity of $2,254,446, and, as a result, were not in compliance with the Stockholders' Equity Requirement. We believe, as of March 9, 2026, we regained compliance with the Stockholders' Equity Requirement based upon our underwritten public offering of 2,238,800 shares of our common stock at a public offering price of $0.50 per share, resulting in gross proceeds of $3,500,000 and net proceeds of approximately $3,360,000 after deducting underwriting discounts, commissions, and estimated offering expenses of $140,000. The offering included 4,761,000 pre-funded warrants at a price of $0.499 per warrant, each exercisable for one share of common stock at a nominal exercise price of $0.001 per share.

Should we fail to satisfy the continued listing requirements for remaining listed on Nasdaq Capital Market, such as the minimum closing bid price requirement or the stockholders' equity requirement, Nasdaq may take steps to delist our common stock. Such a delisting would likely have a negative effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a delisting, we would take actions to restore our compliance with Nasdaq's listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below Nasdaq's minimum bid price requirement or prevent future non-compliance with such listing requirements.

If we cannot maintain the listing of our common stock for trading on Nasdaq, we could face significant material adverse consequences, including:

● a limited availability of market quotations for our common stock;

● reduced liquidity for our common stock;

● a determination that our common stock is a "penny stock" which will require brokers trading in our common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our common stock;

● a limited amount of news and analyst coverage; and

● a decreased ability to issue additional common stock or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as "covered securities." Because our common stock is listed on Nasdaq, such securities will be deemed covered securities. Although the states will be preempted from regulating the sale of our securities, the federal statute does allow states to investigate companies if there is a suspicion of fraud and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. Further, if we were no longer listed on Nasdaq, our securities would not be covered securities and we would be subject to regulations in each state in which we offer our securities.

***Our stock price may be volatile, and purchasers of our common stock could incur substantial losses.***

Since commencement of trading on Nasdaq, our stock price has been extremely volatile. As a result of this volatility, investors may not be able to sell their common stock at or above the price when they purchased our common stock. The market price for our common stock may be influenced by many factors, including the other risks described in this section of this Annual Report entitled "Risk Factors" and the following:

● the
 success of competitive products or technologies;

● regulatory
 or legal developments in the U.S. and other countries, especially changes in laws or regulations applicable to our products;

● introductions
 and announcements of new products by us, our commercialization partners, or our competitors, and the timing of these introductions
 or announcements;

● actions
 taken by regulatory agencies with respect to our products or sales and marketing terms;

● actual
 or anticipated variations in our financial results or those of companies that are perceived to be similar to us;

● the
 success of our efforts to acquire or in-license additional technologies, products or product candidates;

● announcements
 by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments;

● developments
 or disputes concerning patents or other proprietary rights, including patents, litigation matters and our ability to obtain patent
 protection for our products;

● our
 ability or inability to raise additional capital and the terms on which we raise it;

● the
 recruitment or departure of key personnel;

● changes
 in the structure of healthcare payment systems;

● market
 conditions in the pharmaceutical and biotechnology sectors;

● actual
 or anticipated changes in earnings estimates or changes in stock market analyst recommendations regarding our common stock, other
 comparable companies or our industry generally;

● our
 failure or the failure of our competitors to meet analysts' projections or guidance that we or our competitors may give to
 the market;

● fluctuations
 in the valuation of companies perceived by investors to be comparable to us;

● announcement
 and expectation of additional financing efforts;

● speculation
 in the press or investment community;

● trading
 volume of our common stock;

● sales
 of our common stock by us or our stockholders;

● the
 concentrated ownership of our common stock;

● changes
 in accounting principles;

● terrorist
 acts, acts of war or periods of widespread civil unrest;

● natural
 disasters and other calamities; and

● general
 economic, industry and market conditions.

In addition, the stock markets in particular have experienced extreme volatility that has been often unrelated to the operating performance of the issuer. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance.

***The future issuance of equity or of debt securities that are convertible into common stock will dilute our share capital.***

We may choose to raise additional capital in the future, depending on market conditions, strategic considerations and operational requirements. To the extent that additional capital is raised through the issuance of shares or other securities convertible into shares of our common stock, our stockholders will be diluted. Future issuances of our common stock or other equity securities, or the perception that such sales may occur, could adversely affect the trading price of our common stock and impair our ability to raise capital through future offerings of shares or equity securities. No prediction can be made as to the effect, if any, that future sales of common stock or the availability of common stock for future sales will have on the trading price of our common stock.

***If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.***

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities and industry analysts. If no or few securities or industry analysts commence coverage of us, the trading price for our stock would be negatively impacted. In the event we obtain securities or industry analyst coverage, if any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our stock performance, or if our target studies and operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

***Our board of directors has the authority, without stockholder approval, to issue preferred stock with terms that may not be beneficial to holders of our common stock and such issuance could potentially adversely affect stockholders' voting power and perpetuate their control over us.***

Our Certificate of Incorporation, as amended to date, allows us to issue shares of preferred stock without any vote or further action by our stockholders. Our board of directors has the authority to fix and determine the relative rights and preferences of any preferred stock. As a result, our board of directors could authorize the issuance of a series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock and the right to the redemption of the shares, together with a premium, prior to the redemption of shares of our common stock. These rights and preferences could negatively affect the holders of our common stock.

***Our Certificate of Incorporation and Bylaws, each as amended to date, provide for indemnification of officers and directors at the expense of the Company and limit their liability that may result in a major cost to us and hurt the interests of our stockholders because corporate resources may be expended for the benefit of officers and/or directors.***

Our Certificate of Incorporation and Bylaws, each as amended to date, provide for the indemnification of our officers and directors. We have been advised that, in the opinion of the SEC, indemnification for liabilities arising under federal securities laws is against public policy as expressed in the Securities Act and is therefore, unenforceable.

***Our Certificate of Incorporation, as amended to date, provides that disputes must be resolved in the Court of Chancery of the State of Delaware, except for cases brought under the Securities Act or Exchange Act.***

Our Certificate of Incorporation, as amended to date, provides that the Court of Chancery in the State of Delaware will be the exclusive forum for dispute resolution for certain enumerated actions, excluding any actions brought under the Securities Act or Exchange Act, or unless the Company consents in writing to an alternative jurisdiction. This exclusive forum selection clause may cause inconvenience of our stockholders or other stakeholders, should they need to bring suit against the Company for an action other than one arising under the Securities Act or Exchange Act.

***We do not expect to pay cash dividends in the foreseeable future.***

We have never paid cash dividends on our common stock. We do not expect to pay cash dividends on our common stock at any time in the foreseeable future. The future payment of dividends on our common stock directly depends upon our future earnings, capital requirements, financial requirements and other factors that our board of directors will consider. Since we do not anticipate paying cash dividends on our common stock, return on your investment, if any, will depend solely on an increase, if any, in the market value of our common stock.

***Provisions in our amended and restated certificate of incorporation, as amended, and bylaws, as amended, as well as Delaware law, might discourage, delay or prevent a change of control of our company or changes in our management and, therefore, depress the market price of our common stock.***

Our Certificate of Incorporation and Bylaws, each as amended to date, and bylaws contain provisions that could depress the market price of our common stock by acting to discourage, delay, or prevent a change in control of our company or changes in our management that the stockholders of our company may deem advantageous. These provisions, among other things:

● permit
 the board of directors to establish the number of directors;

● provide
 that directors may only be removed "for cause" and only with the approval of 66 2/3 percent of our stockholders;

● require
 super-majority voting to amend some provisions in our Certificate of Incorporation and Bylaws;

● authorize
 the issuance of "blank check" preferred stock that our board of directors could use to implement a stockholder rights
 plan (also known as a "poison pill");

● eliminate
 the ability of our stockholders to call special meetings of stockholders;

● prohibit
 stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

● provide
 that the board of directors is expressly authorized to make, alter or repeal our bylaws; and

● establish
 advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon
 by stockholders at annual stockholder meetings.

In addition, Section 203 of the Delaware General Corporation Law may discourage, delay or prevent a change in control of our company. Section 203 imposes certain restrictions on merger, business combinations and other transactions between us and holders of 15% or more of our common stock.

***Sales of substantial amounts of our securities in the public market could depress the market price of our common stock.***

Our common stock is listed for trading on the Nasdaq Capital Market. If our stockholders sell substantial amounts of our common stock in the public market, or the market perceives that such sales may occur, the market price of our securities could fall and we may be unable to sell our securities in the future.

***Although we have no preferred stock outstanding as of the date hereof and we have currently no intention to issue any preferred stock, our common stockholders could be adversely affected by the issuance by us of preferred stock in the future, if any.***

Our certificate of incorporation does not restrict our ability to offer one or more series of preferred stock, any or all of which could rank equally with or have preferences over our common stock as to dividend payments, voting rights, rights upon liquidation or other types of rights. Our board of directors has the authority, without further action by the stockholders, to issue shares of preferred stock in one or more series and to fix the rights, preferences and the number of shares constituting any series or the designation of such series. In the case our board of directors decides to issue any preferred stock, we would have no obligation to consider the specific interests of the holders of common stock in creating any such series of preferred stock or engaging in any such offering or transaction. Our creation of any series of preferred stock or our engaging in any such offering or transaction could have a material adverse effect on holders of our common stock.

***Trading of our common stock may be limited, making it difficult for our stockholders to sell their shares, and future sales of common stock could reduce our stock price.***

Our common stock currently trades on Nasdaq under the ticker "SHPH." The liquidity of our common stock may be limited, including in terms of the number of shares that can be bought and sold at a given price and reduction in security analysts' and the media's coverage of us, if any. These factors may result in different prices for our common stock than might otherwise be obtained in a more liquid market and could also result in a larger spread between the bid and asked prices for our common stock. In addition, in the absence of a large market capitalization, our common stock is less liquid than the stock of companies with broader public ownership, and, as a result, the trading prices of our common stock may be more volatile. In the absence of an active public trading market, an investor may be unable to liquidate his/her investment in our common stock. Trading of a relatively small volume of our common stock may have a greater impact on the trading price of our stock. We cannot predict the prices at which our common stock will trade in the future, if at all.

***FINRA sales practice requirements may limit a stockholder's ability to buy and sell our securities.***

Effective June 30, 2020, the SEC implemented Regulation Best Interest requiring that "A broker, dealer, or a natural person who is an associated person of a broker or dealer, when making a recommendation of any securities transaction or investment strategy involving securities (including account recommendations) to a retail customer, shall act in the best interest of the retail customer at the time the recommendation is made, without placing the financial or other interest of the broker, dealer, or natural person who is an associated person of a broker or dealer making the recommendation ahead of the interest of the retail customer." This is a significantly higher standard for broker-dealers to recommend securities to retail customers than before under FINRA "suitability rules." FINRA suitability rules do still apply to institutional investors and require that in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending securities to their customers, broker-dealers must make reasonable efforts to obtain information about the customer's financial status, tax status, investment objectives and other information, and for retail customers determine the investment is in the customer's "best interest" and meet other SEC requirements. As a result, fewer broker-dealers may be willing to make a market in our common stock, reducing a stockholder's ability to resell shares of our common stock.

***We are an emerging growth company and a smaller reporting company within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies or smaller reporting companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.***

We are an "emerging growth company" within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including, but not limited to, not being required to comply with the auditor internal controls attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As a result, our shareholders may not have access to certain information they may deem important. We could be an emerging growth company for up to five years following our initial public offering, although circumstances could cause us to lose that status earlier, including if the market value of our common stock held by non-affiliates exceeds $700,000,000 as of any June 30 before that time, in which case we would no longer be an emerging growth company as of the following December 31. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. We have elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Additionally, we are a "smaller reporting company" as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last day of the fiscal year in which (1) the market value of our ordinary shares held by non-affiliates is equal to or exceeds $250,000,000 as of the prior June 30, or (2) our annual revenues equaled or exceeded $100,000,000 during such completed fiscal year and the market value of our ordinary shares held by non-affiliates is equal to or exceeds $700,000,000 as of the prior June 30.

**Item 1B. Unresolved Staff Comments**

None.

**Item 1C. Cybersecurity**

***Risk Management and Strategy***

Together with third-party providers, we have established policies and processes for assessing, identifying, and managing material risks from cybersecurity threats. Accordingly, the assessment and management of material risks from cybersecurity threats, including any unauthorized occurrence on, or conducted through, information systems that may adversely affects the confidentiality, integrity, or availability of such systems or any information residing therein, are primarily undertaken by such third-parties which are reviewed and monitored by our Interim Chief Executive Officer and our Board of Directors.

Our approach to cybersecurity risk management consists principally of the evaluation and selection of third-party vendors and service providers that we believe maintain appropriate cybersecurity programs and safeguards. We have begun to conduct risk assessments at least annually to identify cybersecurity threats. We rely on these third parties to conduct risk assessments, implement and maintain security measures, and monitor the effectiveness of their controls in addressing cybersecurity risks.

As part of our overall risk management program, we provide cybersecurity training to employees in high risk areas and have distributed standard operating procedures to all employees. For additional information regarding whether any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect our company, including our business strategy, results of operations, or financial condition, please refer to Item 1A, "Risk Factors," in this annual report on Form 10-K , including the risk factors entitled *"Failure of our information technology systems could significantly disrupt the operation of our business.*

***Governance***

One of the key functions of our Board of Directors is informed oversight of our risk management process, including risks arising from cybersecurity threats. Our Board of Directors is responsible for monitoring and assessing strategic risk exposure, and our executive officers are responsible for the day-to-day management of the material risks we face. Our Board of Directors administers its cybersecurity risk oversight function directly as a whole.

Our Interim Chief Executive Officer is primarily responsible for assessing and managing material risks from cybersecurity threats on a day-to-day basis.

**Item 2. Properties**

**Facilities**

Our corporate headquarters are presently located in 401 Professional Drive, Suite 260, Gaithersburg, Maryland 20879 where we lease approximately 2,109 square feet of office and laboratory space (together, the "Laboratory Space"), which includes shared access to office space and reception services. We entered into a lease for the new Laboratory Space on June 1, 2023, and the lease has an initial term of 5.25 years and an option to extend for an additional three years, with a monthly rent of $7,206 per month, subject to increase at the rate of 3% per year. All of such space is leased from a non-affiliated third party. We believe that the above facilities are adequate for our current needs.

**Item 3. Legal Proceedings**

Currently, there are no material legal proceedings pending or threatened against us. We are not presently party to any pending or other threatened legal proceedings or claims that we believe will have a material adverse effect on our business, financial condition or operating results, although from time to time, we may become involved in legal proceedings in the ordinary course of business.

**Item 4. Mine Safety Disclosures**

Not applicable.

**PART II**

**Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities**

**Market Information**

Our common stock commenced trading on the Nasdaq Capital Market, under the symbol "SHPH" on August 31, 2022. Prior to that time, our common stock was not traded on any exchange or quoted on any over the counter market.

**Holders**

As of March 24, 2026, we had 65 holders of record of our common stock and 5,591,290 shares of common stock issued and outstanding.

Any future dividends on our common stock will be subject to the discretion of our board of directors and will depend upon, among other things, our earnings (if any), operating results, financial condition and capital requirements, general business conditions and other pertinent facts.

**Preferred dividends**

As of the date of this Annual Report, we have not issued any preferred stock nor paid any preferred dividends.

**Recent Sales of Unregistered Securities**

**Item 6. [Reserved]**

**ITEM 7. MANAGEMENT**'**S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

*The following Management's Discussion and Analysis of Financial Condition and Results of Operations (the "MD&A") should be read in conjunction with our financial statements and the related notes thereto included elsewhere in this Annual Report. The MD&A contains forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations, and intentions. Any statements that are not statements of historical fact are forward-looking statements. When used, the words "believe," "plan," "intend," "anticipate," "target," "estimate," "expect," and the like, and/or future-tense or conditional constructions ("will," "may," "could," "should," etc.), or similar expressions, identify certain of these forward-looking statements. These forward-looking statements are subject to risks and uncertainties that could cause actual results or events to differ materially from those expressed or implied by the forward-looking statements in this Annual Report. Our actual results and the timing of events could differ materially from those anticipated in these forward-looking statements as a result of several factors including, but not limited to, those noted under "Risk Factors" in this Annual Report.* 

*We do not undertake any obligation to update forward-looking statements to reflect events or circumstances occurring after the date of this Annual Report, except as required by U.S. federal securities laws.*

**Overview**

On November 21, 2025, we acquired substantially all of the assets of Molecule.ai, a pharmaceutical software company building an artificial intelligence ("AI") driven platform for molecular discovery and early-stage drug development, were acquired by a wholly owned subsidiary of ours. By combining modern AI techniques with structured scientific workflows, the Molecule.ai platform (hereafter, "Molecule.ai" or the "platform") helps researchers explore the chemical space more efficiently, evaluate molecular ideas with greater clarity and make more informed decisions during the earliest stages of drug development. The platform is engineered to accelerate the iteration cycles that characterize modern drug discovery while preserving scientific reproducibility, traceability and operational reliability. Molecule.ai adapts state of the art AI algorithms to create a practical, domain-specific AI infrastructure layer for molecular research and development. We will seek to leverage Molecule.ai's molecular modeling and predictive analytics platform to significantly augment our drug discovery and development business purpose. In tandem with the Molecule.ai asset acquisition, on November 20, 2025, we committed to a plan to wind-down the Clinical Trials of Ropidoxuridine.

**Nasdaq Listing Compliance**

On December 31, 2024, we received a letter from the Nasdaq Staff 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). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), we had a period of 180 calendar days, or until June 30, 2025, to regain compliance with the Minimum Bid Price Requirement.

Following the 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 failed to evidence compliance upon filing the March 31, 2025 Form 10-Q, we may have been subject to delisting. We evidenced compliance through maintaining a minimum closing bid price of our common stock of $1.00 per share or greater from June 16, 2025 to July 1, 2025. Accordingly, we regained compliance with the Minimum Bid Price Requirement.

On June 16, 2025, in order to maintain the Minimum Bid Price Requirement, we effectuated a 1-for-25 reverse stock split of our issued and outstanding common stock, rounding up to account for any fractional shares. The reverse stock split had no effect on our authorized shares of common stock or preferred stock and the par value will remain unchanged at $0.00001, respectively. All common stock share, option, warrant and per share amounts (except our authorized but unissued shares and previously reserved shares) have been retroactively adjusted in these consolidated financial statements and related disclosures.

On July 2, 2025, we received notification from Nasdaq acknowledging that we maintained the requisite minimum closing bid price of our common stock of $1.00 per share or greater. Accordingly, we regained compliance with Listing Rule 5550(a)(2), and the matter was closed.

We reported stockholders' equity of $1,394,161 in our Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2025, and, as a result, were not in compliance with Nasdaq Listing Rule 5550(b)(1), which requires companies listed on the Nasdaq Capital Market ("Nasdaq") to maintain a minimum of $2,500,000 in stockholders' equity for continued listing (the "Stockholders' Equity Requirement"). We believe as of November 17, 2025, we regained compliance with the Stockholders' Equity Requirement based upon our private placement consummated on November 4, 2025, pursuant to which we raised aggregate gross proceeds of approximately $2.5 million, before deducting placement agent fees and offering expenses payable by us.

For the year ended December 31, 2025, we reported stockholders' equity of $2,254,446, and, as a result, were not in compliance with the Stockholders' Equity Requirement. We believe, as of March 9, 2026, we regained compliance with the Stockholders' Equity Requirement based upon our underwritten public offering of 2,238,800 shares of its common stock at a public offering price of $0.50 per share, resulting in gross proceeds of $3,500,000 and net proceeds of approximately $3,360,000 after deducting underwriting discounts, commissions, and estimated offering expenses of $140,000. The offering included 4,761,000 pre-funded warrants at a price of $0.499 per warrant, each exercisable for one share of common stock at a nominal exercise price of $0.001 per share.

*Research and Development.* Research and development ("R&D") expense was $4.1 million for the year ended December 31, 2025, as compared to $3.6 million for year ended December 31, 2024. The increase primarily relates to costs incurred with the Company's CRO and wind down costs associated with the contract termination. Although R&D expenses increased, the Company anticipates its future research and development activities will cease until such time as it determines the direction of its preclinical and clinical drug development efforts. The Company currently estimates wind down costs associated with Theradex contract termination to be approximately $0.8 million, and for the year ended December 31, 2025, have been recorded in the consolidated statements of operations as research and development expense.

R&D compensation related expenses were $1.2 million in the year ended December 31, 2025 as compared to $1.3 million in the year ended December 31, 2024. For the year ended December 31, 2025, R&D compensation related expenses were 30% as a percent of total R&D expense, representing a decrease from the 35% of total R&D incurred in the year ended December 31, 2024. The decrease in R&D compensation related expenses is largely attributable to the retirement of our former CEO and Chief Scientific Officer in 2025. Subcontractor expense made up 62% of total R&D expenses in the year ended December 31, 2025 and 60% of total R&D expenses during the year ended December 31, 2024.

*General and Administrative Expenses.* General and Administrative expenses in the year ended December 31, 2025 increased by $4.3 million, or 307% from $1.4 million in the year ended December 31, 2024 to $5.7 million in the year ended December 31, 2025. The increase in general and administrative expenses was primarily due to costs associated with advertising for investor relations of $3.5 million, and an increase in general and administrative stock-based compensation expense of $0.2 million.

*Legal and Professional Expenses*. During the year ended December 31, 2025, legal and professional expenses decreased by $0.5 million or 18%. The decrease in legal and professional fees was primarily due to lower expenses related to our public filing requirements, contracts and financing related work that occurred in the year ended December 31, 2025 than compared to the year ended December 31, 2024.

*Other Income (expense)*. During the year ended December 31, 2025, total other expense decreased by $1.6 million or 113% compared to the year ended December 31, 2024. The decrease was primarily driven by a $1.1 million decrease in interest expense resulting from the settlement of the Alto Convertible Note during the year ended December 31, 2024, $0.1 million decrease in the change in fair value of convertible notes, $0.6 million decrease in the change in fair value of derivative liabilities, a $0.2 million decrease in the finance fees, and a $0.8 million decrease in the loss on settlement of convertible debt also due to the settlement of the Alto Convertible Note during the year ended December 31, 2024, partially offset by a $0.3 million increase in gain on settlement of debt.

**Liquidity and Capital Resources**

Our 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 $11.7 million and no revenues generated during the year ended December 31, 2025 and working capital deficit of approximately $7.5 million as of December 31, 2025. We do not expect to generate positive cash flows from operating activities in the near future.

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. As disclosed in our SEC Form 8-K filings on October 21, 2025 and November 21, 2025, the Company received a letter from Theradex Systems, Inc., providing written notice of termination of the master agreement, dated November 1, 2018 (the "Master Agreement"), between us and Theradex, and all work orders thereunder, and demanding immediate payment of all outstanding amounts owed thereunder in the aggregate amount of $1.091 million. Pursuant to the notice of termination, on November 20, 2025, we entered into a release and settlement agreement (the "Settlement Agreement") with Theradex, pursuant to which we will pay a partial payment of $300,000 to Theradex as full and final payment of any and all claims relating to the debt or obligation previously owed by us to Theradex, totaling approximately $557,000 (the "Outstanding Liabilities") and in consideration of such payment, each party will release, acquit and discharge each other from all claims arising from the Outstanding Liabilities and Theradex will properly wind down operations in a manner compliant with the Food and Drug Administration. After the payments pursuant to the Settlement Agreement, we will still owe amounts, under five separate research site agreements between the Company and various hospitals, as disclosed in the Settlement Agreement. As part of the Company's wind down of its Clinical Trials, the Company has incurred expenses that qualify as exit and disposal costs under U.S. GAAP. These include right of use asset impairment charges, accelerated expense recognition of share-based payments, and contract termination costs. Costs associated with the wind down of the Clinical Trials are recorded within research and development expenses in the consolidated financial statements of operations.

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, which we are not obligated to pay until we regain full Nasdaq listing requirement. We received notice from Nasdaq on July 2, 2025 that we had regained compliance with the listing requirement and have since paid the fee.

On April 3, 2025, the Company entered into a consulting agreement with the IR Agency LLC (the "IR Agency"). Pursuant to the consulting agreement, IR Agency agreed to provide certain marketing and advertising services to communicate information about the Company to the financial community, including, but not limited to, creating company profiles, media distribution and building a digital community with respect to the Company. As consideration for the performance of the Services, the Company paid IR Agency $2.0 million on April 5, 2025. The term of the consulting agreement was three months starting on April 3, 2025. For the year ended December 31, 2025, the Company incurred $2.0 million of costs under the consulting agreement.

On September 15, 2025, the Company entered into another consulting agreement with the IR Agency. Pursuant to the consulting agreement, IR Agency agreed to provide marketing and advertising services to communicate information about the Company to the financial community, including, but not limited to, creating company profiles, media distribution and building a digital community with respect to the Company. As consideration for the performance of the Services, the Company paid IR Agency $1.5 million. The term of the consulting agreement will be two months. For the year ended December 31, 2025, the Company incurred $1.5 million of costs under the consulting agreement.

In October 2025, the October 2024 Convertible Bridge Notes mandatorily converted into 117,612 shares of common stock due to reaching maturity. The Convertible Bridge Notes converted at a share price of $6.38, which is the conversion price with a 15% discount per the Convertible Bridge Notes' terms. See Note 5 for more information.

On November 20, 2025, the Company entered into an asset purchase agreement (the "APA") to acquire Molecule.ai. The total purchase consideration was $10,117,304. For the year ended December 31, 2025, the Company made a $3,000,000 cash payment and issued 320,496 shares of common stock with a fair value of $564,073. As of December 31, 2025, the Company had contingent consideration payable and consideration payable of $2,000,000 and $4,435,927, respectively, related to the Molecule.ai acquisition.

Our ability to continue as a going concern is dependent upon our ability to continue to successfully raise additional equity or debt financing to allow us to fund ongoing operations, and commercialize, fund milestone and contingent payments due under the APA, and market our Molecule.ai platform in order to generate revenues. These conditions raise substantial doubt about our ability to continue as a going concern within one year after the date that the consolidated financial statements contained in the report are issued.

***Recent Financings***

On February 27, 2025, we entered into a Revolving Loan Agreement (the "Revolving Loan Agreement") with a lender. 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.

On March 12, 2025, we consummated a public offering of an aggregate of (i) 53,637 shares of common stock, of the Company, at a public offering price of $7.50 per share and (ii) pre-funded warrants to purchase 713,030 shares of common stock at an exercise price of $0.025 per share, at a public offering price of $7.48 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.

On June 20, 2025, we consummated a private placement of an aggregate of (i) 21,924 shares of common stock, of the Company, at a purchase price of $3.60 per share and (ii) pre-funded warrants to purchase 1,158,953 shares of common stock at an exercise price of $0.001 per share, at a purchase price of $3.599 per pre-funded warrant. The private placement closed on June 24, 2025. We received gross proceeds of approximately $4.3 million and net proceeds of approximately $3.9 million, reflecting approximately $0.4 million of legal costs and other expenses connected with the private placement.

On November 3, 2025, we consummated a private placement of prefunded warrants to purchase up to 625,156 shares of common stock at an exercise price of $0.001 per share, at a price of $3.99 per prefunded warrant. The private placement closed on November 4, 2025. We received gross proceeds of approximately $2.5 million and net proceeds of approximately $2.3 million, reflecting approximately $0.2 million of legal costs and other expenses connected with the private placement.

On March 9, 2026, the Company closed an underwritten public offering of 2,238,800 shares of our common stock at a public offering price of $0.50 per share, resulting in gross proceeds of $3.5 million and net proceeds of approximately $3.36 million after deducting underwriting discounts, commissions, and estimated offering expenses of $140,000. The offering included 4,761,200 pre-funded warrants at a price of $0.499 per warrant, each exercisable for one share of common stock at a nominal exercise price of $0.001 per share. The Company used $1.25 million of the net proceeds from this offering for marketing efforts and the remainder will be used for working capital and general corporate purposes.

As of December 31, 2025, total current assets were $0.5 million and total current liabilities were $8.0 million, resulting in working capital deficit of $7.5 million. As of December 31, 2024, total current assets were $2.2 million and total current liabilities were $1.5 million, resulting in a working capital of $0.7 million. The Company's current assets as of December 31, 2025 are comprised of $0.3 million of cash and cash equivalents and $0.2 million of prepaid expenses and other current assets, with the decrease from December 31, 2024 being primarily due to cash paid for Molecule.ai asset acquisition of $3.0 million and costs incurred in winding down of clinical trials.

The Company's current liabilities as of December 31, 2025 are comprised of $1.5 million of accounts payable and accrued expenses, $2.0 million of contingent consideration, and $4.4 million of consideration payable. The increase in current liabilities is primarily due to an increase in contingent consideration and consideration payable of $2.0 million and $4.4 million related to the Molecule.ai acquisition, respectively, as well as an increase in accounts payable and accrued expenses of $0.9 million, partially offset by a $0.7 million decrease in convertible notes payable following their conversion into shares of common stock in October 2024, and a $0.2 million decrease in notes payable to related parties. This is primarily attributable to our efforts to preserve cash while we strive to raise funds to finance ongoing business and operations.

***Cash Flows from Operating Activities***

Our cash flows from operating activities are greatly influenced by our use of cash for operations 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, changes in fair value of our convertible notes, 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.

During the year ended December 31, 2025, net cash used in operating activities of $9.5 million was primarily due to our net loss of $11.7 million, interest payments on convertible notes accounted for at fair value of $0.1 million, and the net change in operating assets and liabilities of $0.5 million, partially offset by stock-based compensation of $0.9 million, gain on settlement of debt of $0.3 million, and depreciation and amortization of $0.3 million.

During the year ended December 31, 2024, net cash flows used in operating activities of $7.3 million was primarily due to our net loss of $9.1 million, change in fair value of derivative liabilities of $0.6 million and change in fair value of convertible notes of $0.1 million, partially offset by loss on settlement of convertible debt of $0.8 million, amortization of debt discount and finance fees of $1.1 million, accrued interest settled with common stock of $0.1 million, expense for debt issuance costs due to fair value election on convertible notes of $0.1 million, stock-based compensation of $0.3 million, and the net change in operating assets and liabilities of $0.1 million.

***Cash Flows from Investing Activities***

For the year ended December 31, 2025, net cash flows used in investing activities was primarily attributable to $3.0 million of cash paid at the close of our acquisition of Molecule.ai. For the year ended December 31, 2024, cash provided by investing activities was primarily attributable to $3.0 million in proceeds from the disposition of marketable securities.

***Cash Flows from Financing Activities***

For the year ended December 31, 2025, cash flows from financing activities was primarily comprised of proceeds of $5.4 million from the sale of common stock and pre-funded warrants as part of the March 2025 equity financing, net of placement agent costs of $0.3 million, and proceeds of $4.1 million, from the sale of common stock and pre-funded warrants as part of the June 2025 equity financing, net of placement agent costs of $0.2 million, proceeds of $2.3 million from the sale of pre-funded warrants as part of the November 2025 equity financing, net of placement agent costs of $0.2 million, partially offset by $0.6 million of payments of other issuance costs for issuance of common stock and equity-classified warrants in the March 2025 and June 2025 equity financings, $0.1 million for finance costs, and $0.2 million of repayment of note payable-related party used to finance our ongoing operations.

For the year ended December 31, 2024, cash flows from financing activities was primarily comprised of net proceeds from the sale of common stock, warrants and pre-funded warrants of $4.0 million, partially offset by $0.3 million of issuance costs, and proceeds from the issuance of convertible notes of $0.8 million, partially offset by issuance costs of $0.1 million, used to finance the Company's ongoing operations.

**Off-Balance Sheet Arrangements**

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

**Critical Accounting Policies and Significant Judgments and Estimates**

This discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP"). The preparation of these 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 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 the significant accounting policies are described in more detail in the notes to the 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.

Our most critical accounting policies and estimates relate to the following:

● Research and Development Expenses

● Fair Value of Convertible Notes

● Fair Value of Warrant to Purchase Common Stock

● Fair Value of Derivative Financial Instruments

● Useful Life of Molecule.ai Intangible Asset

*Research and Development Expense*

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 may include portions of the Company's executives to the extent they are active involved in the research and development activities, materials, supplies, related subcontract expenses, and consulting costs. The periods presented include a portion of the Company's former chief executive officer (prior to his transition to chief scientific officer), former chief operating officer, former vice president regulatory (formerly the chief financial officer) and directors' compensation, prior to the individuals' departures from the Company.

*Fair Value of Convertible Notes*

As permitted under ASC 825, Financial Instruments ("ASC 825"), we elected the fair value option to account for the October 2024 Convertible Bridge Notes. In prior periods, the valuation of the October 2024 Convertible Bridge Notes utilized 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.

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.

In the current reporting period, the Company calculated the fair value of the October 2024 Convertible Bridge Notes immediately prior to their conversion at mandatory conversion based on the fair value of the conversion shares. The fair value was determined by calculating the number of shares into which the October 2024 Convertible Bridge Notes converted upon mandatory conversion, multiplied by the fair value per share of the Company's common stock at the balance sheet date.

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 consolidated statements of operations, or for changes due to our credit worthiness, if any, as a component of other comprehensive income.

*Fair Value of Warrants to Purchase Common Stock*

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.

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.

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 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.

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 simulations or Black-Sholes 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. Black-Sholes Models require specification of the current stock price, exercise price, expected term, expected volatility, a risk-free interest rate aligned with the expected term, and expected dividend yield.

The use of these valuation models requires the input of highly subjective assumptions. Any change to these inputs could produce significantly higher or lower fair value measurements.

*Fair Value of Financial Instruments*

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 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.

For our derivative financial instruments classified as a liability, we use 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 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. The Monte Carlo simulation uses an implied VWAP for valuation. The implied VWAP was back solved by setting the summation of the parts (e.g., derivatives and debt without derivatives) equal to the cash proceeds and is updated each period.

The use of Monte Carlo valuation models require key inputs, some of which are based on estimates and judgments by management. Any change to these key inputs could produce significantly higher or lower fair value measurements.

*Useful Life of Molecule.ai Intangible Asset*

The Company's identifiable intangible asset consists of the Molecule.ai platform classified as developed technology. The Molecule.ai platform is a definite-lived intangible asset and is amortized on a straight-line basis over its estimated 4-year useful life, which reflects the period over which the asset is expected to generate economic benefits. The Company periodically reviews useful life assumptions and related classifications and updates them when facts and circumstances indicate a change is warranted.

**Report of Independent Registered Public Accounting Firm**

To the Shareholders, Board of Directors, and Audit Committee of

Shuttle Pharmaceuticals Holdings, Inc.

**Opinion on the Consolidated Financial Statements**

We have audited the accompanying consolidated balance sheets of Shuttle Pharmaceuticals Holdings, Inc. and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of operations, changes in stockholders' equity, and cash flows for each of the years in the two-year period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP").

**Going Concern**

The accompanying financial statements have been prepared assuming the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has suffered recurring losses and negative cash flows from operations since inception. These conditions as set forth in Note 1, raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**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.

On November 21, 2025, the Company acquired substantially all of the assets of Molecule.ai, a pharmaceutical software company building an artificial intelligence ("AI") driven platform for molecular discovery and early-stage drug development, which were acquired by a wholly owned subsidiary of the Company. By combining modern AI techniques with structured scientific workflows, the Molecule.ai platform (hereafter, "Molecule.ai" or the "platform") helps researchers explore the chemical space more efficiently, evaluate molecular ideas with greater clarity and make more informed decisions during the earliest stages of drug development. The platform is engineered to accelerate the iteration cycles that characterize modern drug discovery while preserving scientific reproducibility, traceability and operational reliability. Molecule.ai adapts state of the art AI algorithms to create a practical, domain-specific AI infrastructure layer for molecular research and development. The acquisition seeks to leverage Molecule.ai's molecular modeling and predictive analytics platform to significantly augment our drug discovery and development business purpose. In tandem with the Molecule.ai asset acquisition, on November 20, 2025, we committed to a plan to wind-down our clinical trials of Ropidoxuridine (the "Clinical Trials"), our lead product candidate (See Note 9).

Molecule.ai is built on three core architectural components: a unified inference engine, an API-first integration layer and a modular model framework. The unified inference engine orchestrates model execution and multi-step reasoning through a deterministic and traceable sequence of operations. Molecule.ai uses an API-first design, which means that all platform capabilities can be accessed programmatically. All predictive and reasoning functions are modular, which allows the platform to expand over time without changing the underlying infrastructure. Molecule.ai currently supports three scientific and computational functions that reflect both its pharmaceutical focus and the structured inference techniques seen in modern agentic LLM systems: (1) molecular property prediction, (2) cross-molecule and cross-property evaluation and (3) prediction reasoning and structured molecular insights. The platform predicts a wide range of molecular properties that are relevant to early-stage discovery and medicinal chemistry and provides inference pipelines for predicting molecular properties. By using transformer-based models, the platform computes predictive outputs on a wide range of therapeutic tasks. The platform evaluates multiple molecules across multiple properties in a unified workflow, helping researchers quickly identify the most-promising candidates, understand trade-offs, and make structured, evidence-based decisions. Molecule.ai also includes a reasoning module that uses LLM-based structured inference to contextualize predictions, explain differences between compounds, perform rule-guided reasoning and produce narrative or structured scientific interpretations with the goal to make complex scientific outputs understandable and actionable for broader research and development audiences.

The broader competitive landscape in the AI ecosystem, especially AI-driven drug discovery, is rapidly advancing toward agentic AI systems and more integrated, end-to-end platforms. To stay at the front of this shift, Molecule.ai is expanding its molecule predictive capabilities, and automated multi-tool workflows. These expansions are designed in accordance with the agentic framework and multi-tool reasoning to further strengthen the platform. A new module will evaluate chemical–protein interaction likelihoods, which will help researchers estimate how molecules may interact with specific biological targets. Molecule.ai is adding biological context reasoning supported by curated genomic and disease-association evidence, which helps tie together chemical ideas with the biological systems they may ultimately affect. The platform will increasingly support insights that connect chemical properties with biological implications, which creates a more complete, end-to-end picture for early research teams. Molecule.ai is also developing an autonomous AI agent designed to reduce manual workload and accelerate early research cycles, which will interpret a discovery objective, plan a series of actions, route each step to the appropriate tools, evaluate preliminary outputs and iterate until a stable result is achieved.

The Molecule.ai platform adheres to strict engineering standards, including reproducibility, traceability, extensibility, scalability and interoperability, which align with modern AI infrastructure expectations for regulated biomedical environments. Molecule.ai aims to become the foundational AI layer for molecular and biological reasoning in pharmaceutical research and development. By integrating property prediction, biological context, multi-step reasoning and agentic automation, the platform seeks to accelerate early discovery while maintaining scientific reliability and operational transparency.

***Liquidity and Going Concern***

Our 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 $11.7 million and no revenues for the year ended December 31, 2025 and working capital deficit of approximately $7.5 million as of December 31, 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. As of December 31, 2025, the Company has not drawn on the revolving note. 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. In November 2025, the Company completed a private placement equity raise that provided $2.2 million net cash proceeds for the issuance of 625,156 pre-funded warrants. However, the Company's existing cash resources, the cash received from the equity offerings, and financing available under the revolving note are not expected to provide sufficient funds to carry out the Company's operations through the next twelve months.

In March 2026, the Company closed an underwritten public offering of 2,238,800 shares of its common stock at a public offering price of $0.50 per share, resulting in gross proceeds of $3.5 million and net proceeds of approximately $3.36 million after deducting underwriting discounts, commissions, and estimated offering expenses of $140,000. The offering included 4,761,200 pre-funded warrants at a price of $0.499 per warrant, each exercisable for one share of common stock at a nominal exercise price of $0.001 per share. The Company intends to use up to $1.5 million of the net proceeds from this offering for future marketing efforts and the remainder for working capital and general corporate purposes.

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, fund milestone and contingent payments due under the APA, and commercialize and market the Molecule.ai platform in order 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 consolidated financial statements are issued.

The accompanying 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***

These consolidated financial statements and related disclosures have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). The consolidated financial statements and disclosures have been prepared using the accrual basis of accounting in accordance with U.S. generally accepted accounting principles ("GAAP").

***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 "August 2024 Reverse Stock Split"). Subsequently, on June 16, 2025, in order to meet the Minimum Bid Price Requirement, the Company effectuated a 1-for-25 reverse stock split of its issued and outstanding common stock, rounding up to account for any fractional shares (the "June 2025 Reverse Stock Split", and collectively with the August 2024 Reverse Stock Split, the "Reverse Stock Splits").

The Reverse Stock Splits had no effect on the Company's authorized shares of common stock or preferred stock and the par value remained unchanged at $0.00001. All common stock share, option, warrant and per share amounts (except our authorized but unissued shares and previously reserved shares) have been retroactively adjusted in these consolidated financial statements and related disclosures.

***Basis of Consolidation***

The consolidated financial statements have been prepared on a consolidated basis with those of the Company's wholly-owned subsidiaries, Shuttle Pharmaceuticals, Inc., Shuttle Diagnostics, Inc., and 1563868 B.C. LTD (d/b/a Molecule.ai). All intercompany transactions and balances have been eliminated.

***Use of Estimates***

The preparation of 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 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 consolidated financial statements for the valuation of debt and warrants, valuation of bifurcated derivative liabilities and other financial instruments, and the useful life of the Molecule.ai intangible asset.

***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 December 31, 2025 and December 31, 2024, 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 December 31, 2025 was approximately $0.1 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.

***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:

● Level 1: Observable inputs such as unadjusted quoted prices in active markets for identical instruments.

● Level 2: Quoted prices for similar instruments that are directly or indirectly observable in the marketplace.

● Level 3: Significant unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires a significant judgment or estimation.

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 December 31, 2025 and December 31, 2024:

See Note 5 and Note 7 for additional disclosures related to the fair value of the Company's convertible notes and derivative liabilities, respectively.

***Derivative Financial Instruments***

The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risks. The Company evaluates all of its 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 consolidated statements of operations.

For its derivative financial instruments, the Company utilizes the most appropriate valuation model (such as Monte Carlo simulations or other sophisticated models, based on the nature of the terms of the instrument) to value the derivative instruments at inception and on subsequent valuation dates. 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 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.

***Convertible Notes***

The Company accounts for its Convertible Bridge Notes (as defined in Note 5) under the fair value option in accordance with ASC 825. The fair value option may be elected on an instrument-by-instrument basis and is irrevocable unless a new election date occurs. Additional term or other notes may be issued in subsequent periods where the Company would be able to make a fair value option election upon issuance provided eligibility criteria are met. The Company records the portion of the Convertible Bridge Notes that are issued and outstanding for accounting purposes at fair value with changes in fair value recorded in other income (expense), net in the consolidated statements of operations, except for the portion of the total change in fair value that results from a change in the instrument-specific credit risk of the Convertible Bridge Notes, which is recorded in other comprehensive income (loss), if applicable. No loss was attributed to changes in credit risk for the periods presented therefore net loss was equal to comprehensive loss. The fair value option election was made to align the accounting for the Convertible Bridge Notes with the Company's financial reporting objectives and reduce operational effort to account for embedded features that otherwise would require bifurcation as a separate unit of account.

Pursuant to the fair value option election, direct and incremental debt issuance costs and consideration paid to the lender related to the Convertible Bridge Notes were expensed as incurred and recorded in other income (expense), net in the consolidated statements of operations.

For convertible notes for which the fair value option is not elected, the Company evaluates the convertible notes for embedded features and bifurcates these features (such as conversion options and redemption options) from their host instruments and accounts for them as free standing derivative financial instruments if certain criteria are met. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument. All of the Company's Convertible Bridge Notes as of December 31, 2025 have been converted.

***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. Finally, the Company determines if the warrants meet the definition of a derivative based on their contractual terms. 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 at 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 consolidated statements of operations. The Company also evaluates if changes in contractual terms or other considerations would result in the reclassification of outstanding warrants from liabilities to stockholders' equity (or vice versa).

***Stock-Based Compensation***

Compensation cost for stock awards, which include restricted stock units ("RSUs"), is measured at the fair value on the grant date and recognized as expense, over the related service period. The fair value of stock awards is based on the quoted price of our common stock on the grant date. Compensation expense related to the RSUs is reduced by the fair value of the units that are forfeited by employees that leave the Company prior to vesting as they occur. Compensation cost for RSUs is recognized using the straight-line method over the requisite service period.

***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 may include portions of the Company's executives to the extent they are active involved in the research and development activities, materials, supplies, related subcontract expenses, and consulting costs.

***Leases***

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use asset ("ROU"), operating lease liability - current, and operating lease liability - noncurrent on the consolidated balance sheets.

ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the related obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the estimated rate of interest for collateralized borrowing, over a similar term of the lease payments at commencement date. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

***Impairment of Long-Lived Assets***

The Company reviews its long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the asset may not be fully recoverable. Recoverability of assets is measured by a comparison of the carrying amount of an asset to the estimated undiscounted cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, an impairment charge will be recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. There were no impairments of long-lived assets during the periods presented.

***Property and Equipment***

Property and equipment are stated at cost less accumulated depreciation. Expenditures for maintenance and repairs are charged to expense as incurred; additions, renewals and betterments are capitalized. When property and equipment are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts, and any gain or loss is included in operations. Depreciation of property and equipment is provided using the straight-line method for substantially all assets with estimated lives as follows:

Furniture 5 years <br> Computers and equipment 5 years <br> Research Equipment 10 years

***Internal-Use Software***

All costs related to the development of internal use software, other than those incurred during the application development stage, are expensed as incurred. Costs incurred during the application development stage are capitalized and amortized over the estimated useful life of the software, which is typically four years. The estimated useful lives of internally developed software are reviewed frequently and adjusted as appropriate to reflect upcoming development activities that may include significant upgrades and/or enhancements to the existing functionality. Capitalized internally developed software costs are amortized on a straight-line basis over their expected economic lives. Amortization of these costs begins once the product is ready for its intended use. The amount of costs capitalized within any period is dependent on the nature of software development activities and projects in each period.

***Intangible Assets***

Intangible assets can include intangible assets acquired as part of business combinations, asset acquisitions and other business transactions. The Company records intangible assets at cost, net of accumulated amortization and accumulated impairment losses, if any. Cost is measured based on the fair values of cash consideration paid and equity interests issued. The cost of an intangible asset acquired is its acquisition date fair value. Amortization of definite life intangible assets is calculated on a straight-line basis over the estimated useful lives of the assets.

***Income Taxes***

The Company accounts for income taxes in accordance with ASC Topic 740, *Income Taxes*. ASC 740 requires a company to use the asset and liability method of accounting for income taxes, whereby deferred tax assets are recognized for deductible temporary differences, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, the Company does not foresee generating taxable income in the near future and utilizing its deferred tax asset, therefore, it is more likely than not that some portion, or all of, the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

Under ASC 740, a tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. The Company has no material uncertain tax positions for any of the reporting periods presented.

***Segment Information***

Operating segments are defined as components of an enterprise about which separate and discrete information is available for evaluation by the chief operating decision-maker ("CODM") in deciding how to allocate resources and assess performance. The Company's CODM, its chief executive officer, evaluates the Company's operations and manages its business as a single operating segment. With the exception of the Molecule.ai intangible asset, substantially all of the Company's long-lived assets are held in the United States. The Molecule.ai intangible asset is recorded on the books of the Company's Canadian subsidiary. Refer to Note 9 for the Company's disclosure on its single operating segment.

***Net Loss Per Common Stock***

Net loss per share of common stock requires presentation of basic and diluted earnings per common share on the face of the 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 to diluted earnings per share.

In the accompanying consolidated financial statements, basic loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the year. Certain warrants issued and outstanding include terms and conditions resulting in the treatment as participating securities. Such warrants do not include an obligation for the warrant holders to fund the losses of the Company. Therefore, these warrants are excluded from the calculation of earnings per common share in periods of net loss.

Diluted earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of shares of common stock outstanding and potentially dilutive shares of common stock during the period to reflect the potential dilution that could occur from common shares issuable through convertible securities, contingent share arrangements, stock options and warrants unless the result would be antidilutive.

The dilutive effect of restricted stock units and other stock-based payment awards subject to vesting and common stock warrants 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.

Given the nominal exercise price of the Company's issuance of Pre-Funded Warrants (as defined in Note 6), such Pre-Funded Warrants are included in the calculation of basic and diluted net loss per share as the exercise price per warrant is deemed nonsubstantive when compared to the fair value of the underlying common shares. The 1,284,109 unexercised pre-funded warrants as of December 31, 2025 were included in the Company's calculation of basic and diluted loss per share.

For the years ended December 31, 2025 and 2024, 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.

***Recently Adopted Accounting Pronouncements***

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The guidance is effective for the Company's fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-09, effective December 31, 2025, in these consolidated financial statements. ASU 2023-09 which only impacted the disclosures and did not otherwise impact the consolidated financial statements. See Note 11, Income Taxes, for disclosures related to the adoption of ASU 2023-09.

***Recently Issued Accounting Pronouncements***

In November 2024, the FASB issued ASU 2024-03, "Disaggregation of Income Statement Expenses ("DISE")," which requires disaggregated disclosure of income statement expenses for public business entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the notes to the financial statements. ASU 2024-03 is effective for all public business entities for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, "Intangibles-Goodwill and Other-Internal-use Software (Subtopic 350-40)," which modernizes the accounting framework for internal-use software. The ASU removes all references to prescriptive and sequential software development stages to reflect the current software development methodologies and frameworks. Under the ASU, an entity is required to start capitalizing software development costs when both of the following occur: (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. ASU 2025-06 is effective for all entities for fiscal years beginning after December 15, 2027, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements and related disclosures.

There have been no other recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance that are of significance or potential significance to the Company.

**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 Real Estate (ARE-QRS-CORP) is the beneficiary of the LOC. The current LOC expires on March 1, 2026.

Following the Company's discontinuation of its clinical trial for Ropidoxuridine, the Company committed to a plan to pursue a sublease for its laboratory space. Although no sublease has been executed as of December 31, 2025, the Company recorded total non-cash impairment charges of $109,235 related to its operating lease right-of-use asset during the year ended December 31, 2025, to reflect the reduced expected economic value of the operating lease right-of-use asset based on estimated sublease rates. The impairment charges are recorded within research and development expenses in the consolidated statements of operations.

The following summarizes the right-of use asset and lease information for the Company's operating leases:

**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 a former 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 December 31, 2025, there was no outstanding principal and interest balances for these related party notes. Under the fair value option, the senior convertible note was $206,085 as of December 31, 2024. The convertible note converted to 39,216 shares of the Company's common stock in October 2025 (see Note 10).

On September 4, 2024, the Company issued a $250,000 promissory note (the "Promissory Note") to a former 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 years ended December 31, 2025 and 2024, the Company incurred $8,730 and $8,692 in interest expense relating to this Promissory Note. For the years ended December 31, 2025 and 2024, the Company repaid principal of $190,270 and $59,730, respectively. For the years ended December 31, 2025 and 2024, the Company paid interest of $9,640 and $6,907, respectively. The principal balance of the Promissory Note as of December 31, 2025 and 2024 was $0 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 and under the terms of 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 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 year ended December 31, 2025, the Company recognized $62,030 in interest expense related to the amortization of these deferred loan costs.

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 December 31, 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 included a 5% original issue discount and the Company received $570,000 in proceeds. The notes were optionally convertible by each holder at a 10% premium beginning three months after the date of issuance, and the conversion price would 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 had the option to prepay the notes at any time for 107% of total outstanding balance and any outstanding principal would 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 was 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 (see Note 4).

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 measured 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.

As of December 31, 2024, 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:

---

| | |
|:---|:---|
|  | **December 31, 2024** |
| Risk-free interest rate | 4.16% |
| Expected term (years) | 0.83 |
| Quoted VWAP | $20.50 |
| Volatility | 57.50% - 97.14 |
| Discount rate | 40% - 60 |
| Probability assessment<sup>1</sup> | 10% - 40 |
| Illiquidity discount | (26)% |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Probability assessments
include the probabilities that subsequent successful capital raises (in terms of amounts raised and timing) are not executed and the
probability that the securities issuable under the convertible bridge notes are not timely registered.

Immediately prior to their mandatory conversion, the Company remeasured the fair value of the Convertible Bridge Notes based on the number of shares to be issued upon conversion and the fair value of the Company's common stock immediately prior to conversion. Upon mandatory conversion of the outstanding principal in October 2025, the Company issued 117,612 shares of common stock. The fair value of the Company's common stock at October 14, 2025 and October 21, 2025 was $3.92 and $3.47 per share.

The following table summarizes the changes in the carrying value of the Convertible Bridge Notes:

---

| | |
|:---|:---|
| **Fair Value Measurements Using Significant Unobservable Inputs (Level 3)** | **Fair Value Measurements Using Significant Unobservable Inputs (Level 3)** |
| Balance - December 31, 2024 | $684205 |
| Conversion of Convertible Bridge Note (at fair value) | (572217) |

***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, in exchange 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 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 8). 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 amending 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 by wire transfer of immediately available funds 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 year ended December 31, 2024, the Company recorded interest expense of $1.2 million, which included amortization of debt discount of $1.1 million. During the year ended December 31, 2024, the Company settled $1.4 million of principal and settled $0.1 million of accrued interest, which settlements were made in the form of 31,894 shares of common stock. During the year ended December 31, 2024, the Company paid $0.8 million of principal and $0.1 million of accrued interest for a total of $0.9 million. In relation to the settlements described above, the convertible debt was settled by September 30, 2024 and the Company recognized a loss on settlement of convertible debt of $0.8 million.

**Note 6 – Molecule.ai Asset Acquisition** 

On November 20, 2025, the Company, through its wholly-owned subsidiary 1563868 B.C. Ltd, entered into an asset purchase agreement with 1542770 B.C. Ltd (the "Selling Party") pursuant to which the Company purchased certain assets of the Selling Party, including, among others, the Selling Party's AI-driven life sciences platform, all as more specifically set forth in the asset purchase agreement. In exchange for the acquired assets, the Company agreed to pay the Selling Parties (i) a cash payment of $3,000,000 at Closing, (ii) a first installment of $3,000,000 payable six months after Closing, and (iii) a second installment of $2,000,000 payable twelve months after closing, with both installments payable in cash or common stock at the Selling Party's discretion, subject to a 19.99% equity issuance cap without shareholder approval. In addition, the Selling Party is entitled to contingent consideration of up to $2,000,000, payable upon achievement of specified technology development milestones within six months post-closing. Any portion of the consideration settled in equity will be measured based on the volume-weighted average price of the Company's common stock over the ten trading days preceding the payment date.

Concurrently, the Company executed a consulting agreement pursuant to which the founder of the Selling Party will provide specified consulting services to enhance, upgrade and develop new features for the AI-driven platform. The term of the consulting agreement is one year, cancellable at any time by either party with thirty days' notice. Total consideration under the consulting agreement is approximately $0.1 million per year, payable in equal monthly installments. The Company concluded that the payments under the consulting agreement are representative of fair market value and there are not economic interdependencies between the asset purchase agreement and the consulting agreement. Therefore, the Company accounts for the consulting agreement and the asset purchase agreement separately.

On December 23, 2025, the parties executed the first amendment to the asset purchase agreement pursuant to which a portion of the first installment payment was accelerated, with the remaining balance payable in accordance with the original terms. The Company issued 320,496 shares of common stock for an aggregate value of approximately $0.6 million, with the remaining $2.4 million payable in May 2026.

The asset purchase agreement contains customary mutual indemnification provisions under which each party agrees to indemnify the other for certain losses arising from breaches of representations, warranties, and covenants and specified pre-/post-closing liabilities, subject to customary limitations such as survival periods, thresholds, and caps.

The total purchase consideration as determined by the Company is as follows:

---

| | |
|:---|:---|
| **Consideration** | **Dollar Value** |
| Closing Cash | $3000000 |
| Accelerated portion of the First Installment | 564073 |
| Six Month Installment | 2435927 |
| Twelve Month Installment | 2000000 |
| Technology Development Milestone 1\* | 1000000 |
| Technology Development Milestone 2\* | 1000000 |
|  | $10000000 |

---

\* These payments are contingent upon certain contingent milestones. The Company has accrued for these payments as of December 31, 2025, as the Company determined that both milestones were probable of being achieved.

The Company incurred approximately $0.1 million of transaction expenses related to the acquisition, which were capitalized and included in the initial carrying value at the date of the acquisition.

The Company accounted for the transaction as an asset acquisition due to the determination that substantially all of the fair value of the assets acquired was concentrated in a group of similar identifiable assets. The Company believes the "substantially all" criterion was met with respect to the acquired intellectual property as it acquired no other assets and assumed no liabilities in the transaction. Further, the Company concluded that the asset acquired represented a developed technology asset as the assets did not meet the definition of an in-process research and development asset. Accordingly, the purchase consideration, plus transaction costs, was allocated to the developed technology asset, with no goodwill recognized. The Company estimates that the developed technology asset has a useful life of four years.

The carrying value of the developed technology asset is summarized as follows:

---

| | |
|:---|:---|
| Carrying value as of December 31, 2024 | $— |
| Developed technology acquired | 10117304 |
| Amortization expense | (288062) |
| Software in progress | 12000 |
| Carrying value as of December 31, 2025 | $9841242 |

***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.

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 years ended December 31, 2025 and 2024, pursuant to agreements with directors, officers and consultants, 231,720 and 44,099 RSUs with a value of $1.1 million and $0.9 million were granted, respectively.

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. On September 8, 2025, the managing partner of Bowery was appointed to the Company's Board of Directors. As a result, Bowery became a related party effective as of that date.

On August 31, 2025 and September 11, 2025, Steve Richards and Joseph Tung, respectively, resigned from their positions on the Board of Directors. Upon the resignation of the two board members, vesting of 7,367 RSUs held by each departing board member, for a total of 14,734 were allowed to accelerate immediately and the remaining unvested RSUs were forfeited. The Company concluded that the acceleration represented a modification of the outstanding unvested RSUs. As a result of the modification, the Company recorded approximately $30,503 of stock-based compensation expense.

On May 8, 2025, the Company and Dr. Anatoly Dritschilo ("Dr. Dritschilo") executed a Settlement Agreement and General Release pursuant to which Dr. Dritschilo agreed to resign from his position as the Company's Chief Scientist Officer and Director of the Company's Board of Directors on May 9, 2025. Under the Agreement and as consideration for timely signing, not timely revoking, and compliance with the promises made therein, the Company agreed to issue 38,565 RSUs, which vest in two years from issuance date. The fair value of the Company's common stock at close of market on May 9, 2025 was $5.825 per share, for an aggregate fair value of the RSUs of $224,641. In November 2025, the Company accelerated recognition of the remaining unrecognized stock-based compensation expense of $170,481 associated with Dr. Dritschilo's Settlement Agreement. As the Company is winding down its clinical trial activities, management concluded the remaining service requirements were no longer substantive; therefore, the remaining expense was recognized in November 2025. The expense is presented within research and development expense for the year ended December 31, 2025, and no additional expense will be recognized thereafter.

On November 21, 2025, Mr. Lorber resigned from his position as Chief Financial Officer. In connection with his resignation, the Company and Mr. Lorber entered into a Separation Agreement and Mutual Release (the "Separation Agreement"). Under the Separation Agreement, specified portions of Mr. Lorber's RSU awards were modified to accelerate and vest on February 8, 2026, which coincided with (i) the expiration of his obligation to remain available for reasonable consultation/inquiries under the Separation Agreement and (ii) the vesting date of the August 12, 2025 RSU award under its original terms. As a result of the modification, 14,999 RSUs were forfeited and 39,854 RSUs remained outstanding and subject to vesting through February 8, 2026. As a result of the modification, the Company recognized incremental stock-based compensation expense of $322 during the year ended December 31, 2025.

As of December 31, 2025, there was $0.3 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 2.47 years.

The following is a summary of activity regarding Restricted Stock Units issued:

---

| | | |
|:---|:---|:---|
|  | **Number of RSU** | **Weighted Average<br> Fair Value Per RSU** |
| Outstanding, December 31, 2024 | 43386 | $21.00 |
| Granted | 231720 | 4.79 |
| Forfeited | (74702) | 5.60 |

**Note 8 – 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 December 31, 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 December 31, 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 December 31, 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. As of December 31, 2024, the Company utilized a Monte Carlo simulation to calculate the fair value of the October 2024 Equity Financing warrants. The key inputs for the Monte Carlo simulation as of December 31, 2024, were as follows:

---

| | |
|:---|:---|
| **Net cash settlement and down round key valuation inputs - warrants\*** | |
| Annualized volatility | 57.50% - 97.14% |
| Risk-free interest rate | 4.4% |
| Quoted VWAP | $0.82 |
| Exercise price | $0.48 |
| Probability assessment<sup>1</sup> | 10% - 40 |
| Illiquidity discount | (26)% |
| Time period (years) | 2.03 - 4.84 |

|:---|:---|
| 1 | Probability assessments include the probabilities that subsequent successful capital raises (in terms of amounts raised and timing) are not executed and the probability that the securities issuable under the convertible bridge notes are not timely registered. |
| \* | *Based on a Monte Carlo simulation analysis of 50,000 iterations* |

---

As of December 31, 2025, the Company utilized a Black-Scholes Model to calculate the fair value of the Alto and October 2024 Equity Financing warrants. The change in methodologies was deemed appropriate due to the conversion of the October 2024 Convertible Notes and reduction in variables and complexities with said instruments no longer outstanding. The key inputs for the Black-Scholes Model as of December 31, 2025, were as follows:

---

| | |
|:---|:---|
|  | **December 31, 2025** |
| Stock price on valuation date | $1.80 |
| Exercise price per share | $3.38 - $35.00 |
| Term (years) | 1.03 - 3.84 |
| Volatility | 112% - 135 |
| Risk-free rate | 3.48% - 3.63 |
| Dividend yield | —% |

**Note 9 – Commitments and Contingencies**

On April 3, 2025, the Company, entered into a consulting agreement with the IR Agency LLC (the "IR Agency"). Pursuant to the consulting agreement, IR Agency agreed to provide certain marketing and advertising services to communicate information about the Company to the financial community, including, but not limited to, creating personnel profiles, media distribution and building a digital community with respect to the Company. As consideration for the performance of the services, the Company paid the IR Agency $2.0 million on April 5, 2025. The term of the consulting agreement was for three months starting on April 3, 2025.

On September 15, 2025, the Company, entered into another consulting agreement with the IR Agency to continue the services contracted for in April 2025. As consideration for the performance of the services, the Company paid the IR Agency $1.5 million. The term of the consulting agreement was for two months. For the year ended December 31, 2025, the Company incurred $3.5 million of costs under the two consulting agreements with the IR Agency.

On December 16, 2024, the Company entered into a sponsored research agreement (the "Sponsored Research Agreement") with the Regents of the University of California, on behalf of its San Francisco campus (the "UCSF"), pursuant to which UCSF's employees will conduct research on a project entitled "Investigation of 18F-fluorodeboronation method for PSMA targeting ligand radiolabeling and evaluation in prostate cancer models" (the "Research Program"). Under the terms of the Sponsored Research Agreement, the Company will bear the total cost of $0.3 million of the Research Program and has an exclusive license to the intellectual property underlying the research. This Sponsored Research Agreement will be effective for a period of one year and may be extended by written mutual consent of the parties. In December 2025, the Sponsored Research Agreement was extended until June 30, 2026. During the year ended December 31, 2025, the Company made prepayments of $0.2 million, respectively, and amortized $0.2 million, respectively, of costs under the Sponsored Research Agreement.

In January 2025, the Company entered into a change order to its existing agreement with Theradex Systems, Inc., the Company's primary third-party CRO, for purposes of supporting the Company's clinical trials of Ropidoxuridine. Following the change order, the Company's total cost limit increased by $3.0 million, for an aggregate of $5.3 million. On October 15, 2025, the Company received a letter from Theradex Systems, Inc., providing written notice of termination of the master agreement, dated November 1, 2018 (the "Master Agreement"), between the Company and Theradex, and all work orders thereunder, and demanding immediate payment of all outstanding amounts owed thereunder in the aggregate amount of $1.1 million. Pursuant to the notice of termination, on November 20, 2025, the Company entered into a release and settlement agreement (the "Settlement Agreement") with Theradex, pursuant to which the Company paid a partial payment of $0.3 million to Theradex as full and final payment of any and all claims relating to the debt or obligation previously owed by the Company to Theradex, totalling approximately $0.6 million (the "Outstanding Liabilities") and in consideration of such payment, each party released, acquitted and discharged each other from all claims arising from the Outstanding Liabilities and Theradex properly winded down operations in a manner compliant with the Food and Drug Administration. After the payments pursuant to the Settlement Agreement, the Company still owes amounts, under five separate research site agreements between the Company and various hospitals, as disclosed in the Settlement Agreement. As part of the Company's wind down of its Clinical Trials, the Company has incurred expenses that qualify as exit and disposal costs under U.S. GAAP. These include right of use asset impairment charges, accelerated expense recognition of share-based payments, and contract termination costs. Costs associated with the wind down of the Clinical Trials are recorded within research and development expenses in the consolidated financial statement of operations. The Company currently estimates wind down costs associated with Theradex contract termination to be approximately $0.8 million and is recorded within accounts payable and accrued expenses on the consolidated balance sheets as of December 31, 2025, and within research and development expenses on the consolidated statements of operations for the year ended December 31, 2025.

In March 2025, the Company entered into a consulting services agreement (the "Consulting Agreement") with Bowery Consulting Group Inc. (the "Consultant"). According to the Consulting Agreement, the Consultant will provide consulting services in connection with the Company's business, advising on viability of plans for scaling activities, growth and capital raising strategies, and costs minimization associated with technological platform improvements and marketing spend. On September 8, 2025, the managing partner of the Consultant was appointed to the Company's board of Directors. As a result, the Consultant became a related party effective as of that date. The Company agreed to pay the Consultant $0.3 million for their services, of which the Company recognized expense of $0.3 million during the year ended December 31, 2025 related to the Consulting Agreement.

On November 10, 2021, the Company entered into an engagement agreement ("EA") with Boustead designating Boustead as its exclusive financial advisor for corporate finance activities and subsequently, on August 29, 2022, the Company entered into an underwriting agreement with Boustead in conjunction with the Company's IPO. The EA contained an up to three year right of first refusal ("ROFR') and the Underwriting Agreement, which overrode conflicting terms in the EA, contained a two year ROFR following the September 2, 2022 closing of the Company's IPO. Further, Boustead also had a ROFR in conjunction with the Company's terminated rights offering, which provided Boutead with a ROFR through February 7, 2025. Following the Company's engagement agreement and underwriting agreement with WestPark Capital dated February 10, 2025 and March 13, 2025, respectively, Boustead asserted it has ROFR rights, demanding termination of WestPark's engagement and claiming entitlement to compensation under the Boustead EA. As of the reporting date, there are no conditions indicating a loss has been incurred, nor does the Company believe a loss is probable and reasonably estimable, therefore no accrual for a potential loss has been recorded.

The Company is, from time to time, involved in various legal proceedings relating to claims arising in the ordinary course of its business. Neither the Company nor any of its subsidiaries is a party to any such legal proceeding the outcome of which, individually or in the aggregate, is expected to have a material adverse effect on the Company's financial position, results of operations or cash flows.

**Note 10 – Business Segment Information**

The Company operates as one operating segment with a focus on the development of novel drug therapies, including cancer therapies, extending new applications of radiation therapy, and other drug development, including through the use of the Molecule.ai platform by the Company as well as licensing the right to use Molecuile.ai to others. The CEO, as our chief operating decision maker (CODM), manages and allocates resources to the operations of the Company on a consolidated basis, considering primarily research and development expenditures, investment in the continued development of the Molecule.ai platform cash burn and net loss. This enables the CEO to assess our overall level of available resources and determine how best to deploy these resources across projects in line with the longer-term Company-wide strategic goals. During the year ended December 31, 2025, the Company appointed an Interim CEO, who assumed the role of CODM. This appointment did not result in any immediate changes to the reporting metrics that the CODM uses to manage and allocate resources to the operations of the Company. Our former CEO continued to chair the Company's Board of Directors and serve in a corporate role as Chief Scientific Officer until his retirement on May 9, 2025.

The accounting policies of our reportable segment are the same as those described in the "Summary of Significant Accounting Policies" for the Company. All costs, research and development expenses, general and administrative expenses, other operating expenses, interest expense, depreciation, corporate overhead assets (workforce, intellectual property, etc.) are fully allocated to the Company's one segment. Significant segment expenses include payroll and costs incurred for the Company's primary third-party contract research organization ("CRO"). The contract with the Company's primary CRO was terminated during the year ended December 31, 2025 following the discontinuation of the clinical trial of Ropidoxuridine (see Note 9). During the years ended December 31, 2025 and 2024, the Company incurred payroll expenses classified in our consolidated statements of operations as research and development of $1.2 million and $1.0 million, respectively. During the years ended December 31, 2025 and 2024, the Company incurred payroll expenses classified in our consolidated statements of operations as general and administrative of $0.6 million and $0.5 million, respectively. During the year ended December 31, 2025, the Company incurred third-party CRO expenses of $2.4 million, all of which is classified in our consolidated statements of operations as research and development. All other operating expenses in our consolidated statements of operations are characterized as other segment expenses which, after factoring in other income and expenses, reconcile to net loss for each period. The Company's reportable segment's profit or loss, assets, significant expenses and other specified items are consistent with the financial information disclosed in our consolidated financial statements. See the consolidated financial statements for the financial information of the Company's one segment.

As of December 31, 2025 and 2024, the Company had approximately $28.0 million and $10.9 million of net operating losses ("NOL") carried forward to offset federal and state taxable income, if any, in the future. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on the assessment, management has established a full valuation allowance against all of the deferred tax asset relating to NOLs for every period because it is more likely than not that all of the deferred tax asset will not be realized.

NOLs created prior to 2018 could be carried back two years and carried forward 20 years. As amended by the Tax Cuts and Jobs Act of 2017 (TCJA), NOLs created after 2017 can no longer be carried back and are instead carried forward indefinitely. The Company has $139,813 and $238,380 of federal NOL carryforwards from 2016 and 2017, respectively, which begin to expire in 2036. The Company has an additional $27.3 million and $26.3 million of federal and state NOLs created after 2017, respectively, which can be carried forward indefinitely. The NOLs can be used to offset future income limited to the lesser of the NOL or 80% of the year's taxable income.

As of December 31, 2025, the Company has $200,715 of federal Research and Development tax credits. These can be carried forward 20 years to offset future federal income tax. These begin to expire in 2037.

The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized from such positions are estimated based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. There are no uncertain tax positions to be reported for the tax years 2025 and 2024.

Beginning in 2022, the Tax Cuts and Jobs Act (the "Tax Act") requires taxpayers to capitalize research and development expenses with amortization periods over five years for domestic research and developments costs and fifteen years for foreign research and development costs. The One Big Beautiful Bill Act (the "OBBBA") was signed into law on July 4, 2025, and contains significant tax law changes, including allowing for the immediate expensing in 2025 and forward of domestic research and development costs. Because of the Company's valuation allowance on its deferred tax assets, the change did not impact the Company's consolidated financial statements.

**Note 12 – Subsequent Events**

On January 6, 2025, the Board of Directors of the Company appointed Ms. Yuying Liang, CPA as Chief Financial Officer of the Company. In connection with this appointment, Mr. Christopher Cooper will no longer serve as the Company's Chief Financial Officer (Principal Financial Officer). Mr. Cooper will continue to serve the Company in his position as Interim Chief Executive Office.

On January 29, 2026, the Company entered into Amendment No. 1 to Mr. Cooper's consulting agreement (the "Amendment") to extend the term of the consulting agreement to August 1, 2026, effective September 11, 2025. In accordance with the terms of the consulting agreement, Mr. Cooper will receive compensation of $20,000 per month. The consulting agreement may be terminated by either party upon 30 days' notice, and may be terminated for cause immediately. Mr. Cooper will be expected to work 40 hours per week and will be subject to standard confidentiality and non-disclosure provisions.

In January and February 2026, the Company issued a total of 1,284,109 shares of common stock from the Pre-Funded Warrant Shares reserved for issuance upon the exercise of Pre-Funded Warrants. Following the exercises in January and February 2026, all Pre-Funded Warrants outstanding as of December 31, 2025, have been exercised.

On March 9 2026, the Company closed an underwritten public offering of 2,238,800 shares of its common stock at a public offering price of $0.50 per share, resulting in gross proceeds of $3.5 million and net proceeds of approximately $3.36 million after deducting underwriting discounts, commissions, and estimated offering expenses of $140,000. The offering included 4,761,200 pre-funded warrants at a price of $0.499 per warrant, each exercisable for one share of common stock at a nominal exercise price of $0.001 per share. The Company intends to use up to $1.5 million of the net proceeds from this offering for future marketing efforts and the remainder for working capital and general corporate purposes.

In March 2026, the Company made a payment of $1.25 million to IR Agency related to certain marketing and advertising services.

**Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure** 

On March 21, 2023, the Company's audit committee selected Forvis Mazars, LLP (the "New Accountant") to serve as the Company's independent registered public accounting firm for the review of its Quarterly Reports on Form 10-Q and Annual Report on Form 10-K for the year ending December 31, 2023. As a result, the audit committee determined that BF Borgers CPA PC (the "Former Accountant") would no longer serve as the Company's independent registered public accounting firm, effective as of March 21, 2023.

On March 22, 2023, the Company filed a Current Report on Form 8-K (the "Original Form 8-K") with the SEC disclosing the changes in its certifying accountant.

As disclosed in the Original Form 8-K, the Former Accountant's audit report on our financial statements for the years ended December 31, 2021 and 2022 contained no adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope or accounting principles, except that the audit report on the financial statements of the Company for the year ended December 31, 2021 contained an uncertainty about the Company's ability to continue as a going concern (the "Going Concern Opinion"). The Former Auditor's Going Concern Opinion was resolved following the Company's completion of its approximately $11.4 million initial public offering in September 2022 and subsequent $4.0 million private placement in January 2023.

When the Former Accountant was engaged through its dismissal in March 2023, for the years ended December 31, 2022 and 2021 and through the date of the Original Form 8-K, the Company had no "disagreements" (as defined in Regulation S-K, Item 304(a)(1)(iv) and the related instructions) with the Former Accountant on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to the satisfaction of the Former Accountant would have caused them to make reference thereto in their reports on the financial statements for such periods.

There were no reportable events for the years ended December 31, 2022 or 2021 and through the date of the Original Form 8-K, there were no reportable events as defined in item 304(a)(1)(v) of Regulation S-K.

As also disclosed in the Form 8-K, prior to retaining the New Accountant, the Company did not consult with the New Accountant regarding either: (i) the application of accounting principles to a specified transaction, either contemplated or proposed, or the type of audit opinion that might be rendered on the Company's financial statements; or (ii) any matter that was the subject of a "disagreement" or a "reportable event" (as those terms are defined in Item 304(a)(1)(iv) and (a)(1)(v) of Regulation S-K, respectively).

On March 21, 2023, the Company provided the Former Accountant with the disclosures contained in the Form 8-K disclosing the dismissal of the Former Accountant and requested in writing that the Former Accountant furnish the Company with a letter addressed to the SEC stating whether or not they agree with such disclosures. The Former Accountant's response was filed as Exhibit 16.1 to the Original Form 8-K.

On May 3, 2024, the SEC entered a cease-and-desist order against our Former Accountant, which resulted in the Re-audit of our financial statements for the year ended December 31, 2022, which had been audited by our Former Accountant. Since that time and as a result of the Re-audit, as of July 10, 2024, the Company and the audit committee of our board of directors, in consultation with our current auditor, Forvis Mazars LLP, concluded that our audited financial statements for the year ended December 31, 2022, our audited financial statements for the year ended December 31, 2023 and the quarterly periods included in the Company's 2023 Form 10-K, and the Quarterly Report on Form 10-Q for the period ended March 31, 2024, required restatement and were not reliable. We reported this determination in our Form 8-K filed on July 16, 2024 and subsequently filed an Annual Report on Form 10-K/A amending the Company's 2023 Form 10-K and a Quarterly Report on form 10-Q/A amending the Company's Form 10-Q for the period ended March 31, 2024, which reports were each filed on September 4, 2024.

**Item 9A. Controls and Procedures**

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Exchange Act Rule 15d-15(e)) are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act, such as this report, is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including our Interim Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

As of December 31, 2025, our management carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures. Such evaluation was carried out under the supervision of our Interim Chief Executive Officer by our Chief Financial Officer, and our third-party financial service provider. Based on this evaluation, management concluded that our disclosure controls and procedures were, and continues to be, ineffective as of December 31, 2025. Based on the foregoing, our management concluded that our internal controls over the following financial reporting areas to be material weaknesses:

● Our written policies and procedures over accounting transaction processing and period end financial close and reporting are limited, which has resulted in ineffective oversight in the establishment of proper monitoring controls over accounting and financial reporting; in addition, we lacked sufficient review and segregation of duties for certain financial transactions, manual journal entries, and critical financial spreadsheets, such that a proper review had not been performed by someone other than preparer, and that process documentation is lacking for review and monitoring controls over accounting and financial reporting.

● We identified findings related to overall information technology general controls ("ITGCs") including issues with super-user access and segregation of duties for systems supporting the Company's internal control processes and controls.

● We identified deficiencies in our entity level controls specifically related to timely communication of material contracts and other communications for consideration in the Company's accounting and financial reporting processes.

Other than as noted below, there has been no change in the Company's internal control over financial reporting during the fiscal year ended December 31, 2025 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting. Management will continue to monitor and evaluate the effectiveness of our internal controls and procedures over financial reporting on an ongoing basis and are committed to taking further action and implementing additional improvements as necessary.

Management's Remediation Measures

While the Company has improved its organizational capabilities, the Company's remediation efforts will continue to take place.
