Item 1A. Risk Factors

Investment in our securities involves a high degree of risk. You should consider carefully the risks described below, together with other information in this Annual Report and other public filings, before making investment decisions regarding our securities. If any of the following events actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our common stock to decline and you may lose all or part of your investment. Moreover, the risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, operating results, prospects or financial condition.

Risks Related to Our Review of Strategic Alternatives

We may not be successful in identifying and implementing any potential strategic alternatives in a timely manner, or at all, and any strategic transactions that we may consummate in the future could have negative consequences.

In July 2024, we announced that we are undertaking a comprehensive exploration of strategic alternatives focused on maximizing stockholder value. We expect to devote substantial time and resources to exploring strategic alternatives that our Board believes will maximize stockholder value. Despite management devoting significant efforts to identify and evaluate potential strategic alternatives, there can be no assurance that this strategic review process will result in us pursuing any transaction or that we will be able to successfully consummate any particular strategic transaction on attractive terms, on a timely basis, or at all. For example, certain types of strategic transactions may require third-party consents, such as stockholder approval, which could be difficult or costly to obtain. We have not set a timetable for completion of this strategic review process, and our Board has not approved a definitive course of action. Additionally, there can be no assurance that any particular course of action, business arrangement or transaction, or series of transactions, will be pursued, successfully consummated or lead to increased stockholder value or that we will make any cash distributions to our stockholders.

The process of continuing to evaluate our strategic alternatives may be costly, time-consuming and complex, and we may incur significant legal, accounting and advisory fees and other expenses, some of which may be incurred regardless of whether we successfully enter into a transaction. We may also incur additional unanticipated expenses in connection with this process. Any such expenses will decrease the remaining cash available for use in our business. Our ability to pursue or consummate strategic transactions also depends upon our ability to retain certain of our employees, the loss of whose services may adversely impact the ability to

---

identify, negotiate and consummate such transaction. If we are unable to successfully retain certain of our key remaining personnel, we are at risk of a disruption to our exploration and consummation of one or more strategic transactions.

In addition, potential counterparties in a strategic transaction involving us may place minimal or no value on our assets and our public listing. Further, should we resume the development of future drug candidates, such as one or more of the programs in our pipeline for which we halted further development, the development and any potential commercialization of our future drug candidates will require substantial additional cash to fund the costs associated with conducting the necessary preclinical and clinical testing and obtaining regulatory approval. If our existing third party manufacturers, or the third parties that we engage in the future to manufacture a product or component for commercial sale or for our clinical trials should cease to continue to do so for any reason, we likely would experience delays in obtaining sufficient quantities of our drug candidates for us to meet commercial demand or to advance our clinical trials while we identify and qualify replacement suppliers. Consequently, any potential counterparty in a strategic transaction involving us may choose not to spend additional resources to resume or continue development of our future drug candidates and may attribute little or no value, in such a transaction, to our future drug candidates.

In addition, any strategic transactions that we may pursue could have a variety of negative consequences, and we may enter into a transaction that yields unexpected results that adversely affect our business and decreases the remaining cash available for use in our business. Any potential transaction would be dependent on a number of factors that may be beyond our control, including, among other things, market conditions, industry trends, the interest of third parties in a potential transaction with us, obtaining stockholder approval and the availability of financing to third parties in a potential transaction with us on reasonable terms. There can be no assurance that any particular course of action, business arrangement or transaction, or series of transactions, will be pursued, successfully consummated, lead to increased stockholder value, or achieve the anticipated results.

If we are not successful in setting forth a new strategic path for us, or if our plans are not executed in a timely fashion, this may cause reputational harm with our stockholders and the value of our securities may be adversely impacted. In addition, speculation regarding any developments related to the review of strategic alternatives and perceived uncertainties related to the future of us could cause our stock price to fluctuate significantly.

Even if we successfully consummate any strategic transaction, or series of transactions, from our strategic assessment, we may fail to realize all or any of the anticipated benefits of any such transaction, such benefits may take longer to realize than expected, we may encounter integration difficulties or we may be exposed to other operational and financial risks.

Our ability to realize the anticipated benefits of any potential strategic transaction will depend on a number of factors, including our ability to integrate with any future business partner, our ability to obtain value for portions of our business, if divested, and our ability to generate future stockholder value. The process may be disruptive to our business, and the expected benefits may not be achieved within the anticipated time frame, or at all. The failure to overcome the challenges involved and to realize the anticipated benefits of any potential transaction could adversely affect our business and financial condition. The negotiation and consummation of any potential strategic transaction will require significant time on the part of our management, and the diversion of management’s attention may disrupt our business.

The negotiation and consummation of any such transaction may also require more time or greater cash resources than we anticipate and expose us to other operational and financial risks, including, but not limited to, increased near-term and long-term expenditures, exposure to unknown liabilities, higher than expected acquisition or integration costs, incurrence of substantial debt or dilutive issuances of equity securities to fund future operations, including financings in connection with a strategic transaction, write-downs of assets or goodwill or incurrence of non-recurring, impairment or other charges, increased amortization expenses, difficulty and cost in combining the operations and personnel of any acquired or acquiring business with our operations and personnel, impairment of relationships with key suppliers or customers of any acquired or acquiring business due to changes in management and ownership, inability to retain our key employees or any acquired or acquiring business and possibility of future litigation. Any of the foregoing risks could have a material adverse effect on our business, financial condition and prospects.

If a strategic transaction is not consummated, our Board may decide to pursue a dissolution and liquidation. In such an event, the amount of cash available for distribution to our stockholders will depend significantly on the timing of such liquidation as well as the amount of cash that may need to be reserved for commitments and contingent liabilities.

If we do not successfully consummate a strategic transaction, our Board may decide to pursue a dissolution and liquidation. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such decision and, with the passage of time, the amount of cash available for distribution will be reduced as we continue to fund our operations. In addition, if our Board were to approve and recommend, and our stockholders were to approve, a dissolution and liquidation, we would be required under Delaware corporate law to pay our outstanding obligations, as well as to make reasonable provision for contingent and unknown obligations, prior to making any distributions in liquidation to our stockholders. As a result of this requirement, a portion of our assets may need to be reserved pending the resolution of such obligations and the timing of any such resolution is uncertain. In addition, we may be subject to litigation or other claims related to a dissolution and liquidation. If a dissolution and liquidation were pursued, our Board, in consultation with our advisors, would need to evaluate these matters and make a determination

---

about a reasonable amount to reserve. Accordingly, holders of our common stock could lose all or a significant portion of their investment in the event of a liquidation, dissolution or winding up.

The value to stockholders in the event of a strategic transaction or dissolution may depend on the extent to which we will be able to successfully satisfy our existing contractual obligations to third parties and regulatory commitments on favorable terms, which may include the outcome of our negotiations to reduce or terminate such commitments.

We are currently subject to certain contractual and regulatory obligations and commitments. In connection with our comprehensive exploration of strategic alternatives, we may seek to negotiate with third parties in order to reduce or eliminate such obligations and commitments. Our ability to successfully negotiate such obligations or commitments on favorable terms, or at all, or our ability to satisfy any such obligations may impact our ability to pursue a strategic transaction on terms favorable to us, the resulting value to stockholders in a strategic transaction or the cash available for distribution to our stockholders in the event of our dissolution. We may also incur substantial costs in connection with or as a result of such negotiations or termination of any of our commitments. There can be no assurance that we will be successful in negotiating to reduce or eliminate any of our existing contractual or regulatory obligations and commitments, or that we will be able to satisfy any such obligations on a timetable that will allow us to maximize potential value to our stockholders.

We may become involved in litigation, including securities class action litigation, that could divert our management’s attention and harm our business, and insurance coverage may not be sufficient to cover all costs and damages.

In the past, litigation, including securities class action litigation, has often followed certain significant business transactions, such as the sale of a company or announcement of any other strategic transaction, or the announcement of negative events. These events may also result in investigations by the SEC. We may be exposed to such litigation even if no wrongdoing occurred. Litigation is usually expensive and diverts management’s attention and resources, which could adversely affect our business and cash resources and our ability to consummate a potential strategic transaction or the ultimate value our stockholders receive in any such transaction.

Our workforce reduction may not achieve our intended outcome and may result in significant adverse consequences.

In July 2024, in connection with our evaluation of strategic alternatives, our Board approved a reduction-in-force to continue in stages as our operational and strategic direction evolves. This reduction-in-force may result in unintended consequences and costs, such as the loss of institutional knowledge and expertise, attrition beyond the intended number of employees, decreased morale among our remaining employees, and the risk that we may not achieve the anticipated benefits of the reduction-in-force. In addition, while positions have been eliminated, certain functions necessary to our operations remain, and we may be unsuccessful in distributing the duties and obligations of departed employees among our remaining employees. The reduction-in-force could also make it difficult for us to pursue, or prevent us from pursuing, new opportunities and initiatives due to insufficient personnel, or require us to incur additional and unanticipated costs to hire new personnel to pursue such opportunities or initiatives, including any potential strategic alternatives. If we are unable to realize the anticipated benefits from the reduction-in-force, or if we experience significant adverse consequences from the reduction-in-force, our business, financial condition, and results of operations may be materially adversely affected.

Risks Related to Our Financial Condition and Capital Requirements

We have incurred significant losses from our inception, and we anticipate that we may incur losses in the foreseeable future.

We are a clinical-stage pharmaceutical company. Until recently, we had focused our efforts primarily on developing voruciclib, a selective orally administered CDK9 inhibitor, and ME-344, an intravenous small molecule mitochondrial inhibitor targeting the oxidative phosphorylation pathway, with the goal of achieving regulatory approval. In connection with our decision to undertake a comprehensive exploration of strategic alternatives, we have discontinued our clinical programs involving voruciclib and ME-344.

Since inception, we have incurred significant operating losses. During the fiscal year ended June 30, 2024, we had net income of $17.8 million, while during the fiscal year ended June 30, 2023, we incurred a net loss of $31.8 million. As of June 30, 2024, we have an accumulated deficit of $388.2 million. In connection with the termination of all ongoing clinical programs noted above, our research and development expenses have decreased. We expect to continue to incur costs and expenditures in connection with the process of evaluating our strategic alternatives.

Should we resume development activities in the future, we expect that research and development costs would increase significantly and we would continue to incur significant expenses and operating and net losses, as we develop and seek regulatory approval for such drug candidates.

Our financial results may fluctuate significantly from year to year, depending on whether we resume development of our drug candidates or any future drug candidates, the timing of any clinical trials, the receipt of payments under any future agreements we may

---

enter into, and our expenditures on other research and development (R&D) activities as well as any payments owed under the License Agreement with Presage and any future similar agreements.

Should we resume the development activities in the future, we expect we would to continue to incur significant losses for the foreseeable future as we:

Because of the numerous risks and uncertainties associated with pharmaceutical drug development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability. If we are required by the FDA or foreign regulatory authorities, to perform studies in addition to those currently expected, or if there are any delays in completing our clinical trials or the development of our drug candidate, our expenses could increase.

If we decide to resume development of our drug candidate or any future drug candidate, we will need additional funding and may be unable to raise capital when needed, which would force us to delay, reduce or eliminate our drug development programs.

Conducting clinical trials, pursuing regulatory approvals, establishing outsourced manufacturing relationships, and successfully manufacturing and commercializing drugs and drug candidates is expensive. If we resume development of our drug candidates or any future drug candidate, we will need to raise additional capital to continue such development. In order to expand our pipeline of drug candidates for future development, we may need to purchase or in-license any such drug candidates.

In July 2024, we discontinued the clinical program in our pipeline in connection with our undertaking a comprehensive exploration of strategic alternatives focused on maximizing stockholder value. In connection with our streamlined operating plan, we commenced a reduction-in-force.

After taking into account the discontinuation of our clinical development programs, reduction-in-force and comprehensive exploration of strategic alternatives, we expect that our current unrestricted cash and cash equivalents and short-term investments will be sufficient to fund our currently anticipated operating plan for at least the next 12 months. In connection with the termination of all ongoing clinical programs, our research and development expenses have decreased. We expect to continue to incur costs and expenditures in connection with the process of evaluating our strategic alternatives. Should we resume development activities in the future, we expect that research and development costs would increase significantly. It is possible that the assumptions upon which we have based this estimate may prove to be wrong, and we could use our capital resources sooner than we presently expect.

Our future funding requirements will depend on many factors, including, but not limited to:

Future capital requirements will also depend on the extent to which we acquire or invest in additional complementary businesses, products and technologies. Until we can generate a sufficient amount of product revenue, if ever, we may seek to finance future cash needs through public or private equity offerings, debt financings, milestone and royalty payments from corporate collaboration and licensing arrangements, as well as through interest income earned on cash and investment balances. Our future revenues, profitability and access to capital will be affected by the continuing efforts of governmental and private third party payers to manage, contain or reduce the costs of health care through various means, such as capping prices, limiting price increases, reducing reimbursement, and requiring rebates. We cannot be certain that additional funding will be available on acceptable terms, or at all, and our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions, including high rates of inflation and interest rates, the continuing disruptions to

---

and volatility in the credit and financial markets in the United States and worldwide, including resulting from the ongoing conflicts between Russia and the Ukraine, conflicts in the Middle East, and increasing tensions between China and Taiwan.

Risks Related to Any Future Development and Commercialization of Our Drug and Potential Drug Candidates

Should we resume development of our drug candidate or future drug candidates, if we are unable to successfully complete clinical development, obtain regulatory approvals and commercialize our drug candidate or future drug candidates, or experience significant delays in doing so, our business will be materially harmed.

In July 2024, we discontinued the clinical programs in our pipeline in connection with our undertaking a comprehensive exploration of strategic alternatives. Should we resume development activities in the future, we cannot be certain that any such drug candidates will be successful in clinical trials or receive regulatory approval. Regulatory authorities may interpret our data differently than we do. We are not permitted to market or promote any of our drug candidates before we receive regulatory approval from the FDA or comparable foreign regulatory authorities; should we resume development activities in the future we may never receive such regulatory approval for voruciclib or any future drug candidates.

Should we resume development of our drug candidate or any future drug candidates, the success of such drug candidates will depend on many factors, including but not limited to:

● successful enrollment in, and completion of, clinical trials, as well as completion of preclinical studies;

● favorable efficacy and acceptable safety data from our clinical trials and other studies;

● receipt of additional regulatory approvals;

● managing our reliance on sole-source third parties such as our third-party vendors, suppliers, and manufacturers;

● the performance by CROs or other third parties and consultants we may retain of their duties to us in a manner that complies with our protocols and applicable laws and that protects the integrity of the resulting data;

● obtaining and maintaining patent, trade secret and other intellectual property protection and regulatory exclusivity;

● ensuring we do not infringe, misappropriate or otherwise violate the valid patent, trade secret or other intellectual property rights of third parties;

● successfully launching, either alone or with a commercial partner, any drug candidate for which regulatory approval is received;

● obtaining and maintaining favorable reimbursement from third-party payers and governments for drugs and drug candidates;

● competition with other drugs;

● post-marketing commitments, if any, to regulatory agencies following regulatory approval of any drug candidate;

● continued acceptable safety profile following regulatory approval; and

● manufacturing or obtaining sufficient supplies of our drugs and any drug candidate that may be necessary for use in clinical trials for evaluation of any drug candidate and commercialization of any approved drug.

If we do not achieve and maintain one or more of these factors in a timely manner or at all, we could experience significant delays in our ability to, or be unable to obtain regulatory approvals for, and/or to successfully commercialize any drugs or drug candidates, which would materially harm our business and we may not be able to generate sufficient revenues and cash flows to continue our operations.

Risks Related to Our Intellectual Property

The value of our intellectual property is dependent, in part, on obtaining and maintaining patent protection and preserving trade secrets, which cannot be guaranteed.

Patent protection and trade secret protection are important to our business and our future will depend, in part on our ability to maintain trade secret protection, obtain patents and operate without infringing the proprietary rights of others both in the U.S. and abroad. Litigation or other legal proceedings may be necessary to defend against claims of infringement, to enforce our patents or to protect our trade secrets. Such litigation could result in substantial costs and diversion of our management’s attention.

The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. We acquired patents and patent applications related to voruciclib from Presage in 2017, and acquired both issued patents and pending patent applications related to ME-344 from Novogen in relation to its Isoflavone-based compounds, which we previously licensed from Novogen, in 2011. Additionally, Novogen had previously applied for patents in a number of countries with

---

respect to the use of their isoflavone compounds, including ME-344. Finally, in September 2013, we acquired patents and patent applications related to zandelisib from Pathway Therapeutics, Inc.

The patent applications may not proceed to grant or may be amended to reduce the scope of protection of any patent granted. The applications and patents may also be opposed or challenged by third parties. Should we resume development of our drug candidate or any future drug candidates, our commercial success will depend, in part, on our ability to obtain and maintain effective patent protection for our compounds and their use in treating, preventing, or curing cancer, and to successfully defend patent rights in those technologies against third-party challenges. Any of these events could prevent us from achieving or maintaining regulatory product approval and market acceptance of the particular drug candidate, if approved, or could substantially increase the costs and expenses of developing and commercializing such product, which in turn could delay or prevent us from generating significant revenues from our sale. As patent applications in the U.S. are maintained in secrecy until published or issued and as publication of discoveries in the scientific or patent literature often lag behind the actual discoveries, we cannot be certain that we or Presage were the first to make the inventions covered by the pending patent applications or issued patents referred to above or that we or they were the first to file patent applications for such inventions. Additionally, the breadth of claims allowed in biotechnology and pharmaceutical patents or their enforceability cannot be predicted. We cannot be sure that, should any patents issue, we will be provided with adequate protection against potentially competitive products. Furthermore, we cannot be sure that should patents issue, they will be of commercial value to us, or that private parties, including competitors, will not successfully challenge our patents or circumvent our patent position in the U.S. or abroad.

General Business Risks

Our employees, independent contractors, consultants, commercial partners, principal investigators, or CROs may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have a material adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees, independent contractors, consultants, commercial partners, manufacturers, investigators, or CROs could include intentional, reckless, negligent, or unintentional failures to comply with FDA regulations, comply with applicable fraud and abuse laws, provide accurate information to the FDA, properly calculate pricing information required by federal programs, comply with federal procurement rules or contract terms, report financial information or data accurately or disclose unauthorized activities to us. This misconduct could also involve the improper use or misrepresentation of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter this type of misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. Moreover, it is possible for a whistleblower to pursue a False Claims Act (FCA), case against us even if the government considers the claim unmeritorious and declines to intervene, which could require us to incur costs defending against such a claim. Moreover, it is possible for a whistleblower to pursue a False Claims Act, (“FCA”), case against us even if the government considers the claim unmeritorious and declines to intervene, which could require us to incur costs defending against such a claim. Further, due to the risk that a judgment in an FCA case could result in exclusion from federal health programs or debarment from government contracts, whistleblower cases often result in large settlements. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, financial condition, and results of operations, including the imposition of significant fines or other sanctions.

Our business and operations would suffer in the event of system failures.

Our internal computer systems and those of our CROs and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical failures. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug candidate development and, if such drug candidates are approved commercialization programs. For example, the loss of clinical trial data from completed, ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of personal, confidential or proprietary information, we could incur liability and regulatory enforcement actions, and the further development of any of our drug candidates could be delayed.

Our efforts will be seriously jeopardized if we are unable to retain and attract key employees.

Our success depends on the continued contributions of our principal management, development and scientific personnel. We face competition for such personnel, and we believe that risks and uncertainties related to our business, including the timing and risk associated with research and development, our available and anticipated cash resources, and the volatility of our stock price, may impact our ability to hire and retain key and other personnel. The loss of services of our Acting Chief Executive Officer, Chief Financial Officer or other key employees could adversely impact our operations and ability to generate or raise additional capital. The loss of services of our Chief Executive Officer or other key employees could adversely impact our operations and ability to generate or raise additional capital.

---

Negative U.S. and global economic conditions may pose challenges to our business strategy, which relies on funding from the financial markets or collaborators.

Negative conditions in the U.S. or global economy, including financial markets, may adversely affect our business and the business of current and prospective vendors, licensees and collaborators, and others with whom we do or may conduct business. The duration and severity of these conditions is uncertain. If negative economic conditions occur, we may be unable to secure funding on terms satisfactory to us to sustain our operations or to find suitable collaborators to advance our internal programs, even if we achieve positive results from our drug development programs.

Laws, rules and regulations relating to public companies may be costly and impact our ability to attract and retain directors and executive officers.

Laws and regulations affecting public companies, including rules adopted by the SEC and by Nasdaq, may result in increased costs to us. These laws, rules and regulations could make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our Board, on our board committees or as executive officers. We cannot estimate accurately the amount or timing of additional costs we may incur to respond to these laws, rules and regulations.

Security breaches and privacy issues could compromise our information and expose us to liability, which would cause our business and reputation to suffer.

In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information and that of our suppliers, as well as personally identifiable information of clinical trial participants and employees. Similarly, our third-party providers possess certain of our sensitive protected health data. Similarly, our third party providers possess certain of our sensitive protected health data. The secure maintenance of this information is critical to our operations and business strategy. Despite our reasonable security measures, our information technology and infrastructure may be vulnerable to cyber-attacks or breached due to employee error, malfeasance or other disruptions. Cyber-attacks and other security incidents are increasing in their frequency, levels of persistence, sophistication and intensity, and are being conducted by sophisticated and organized groups and individuals with a wide range of motives and expertise. Cyber attacks and other security incidents are increasing in their frequency, levels of persistence, sophistication and intensity, and are being conducted by sophisticated and organized groups and individuals with a wide range of motives and expertise. Although we develop and maintain systems and controls designed to prevent these events from occurring, and we have a process to identify and mitigate threats, the development and maintenance of these systems, controls and processes is costly and requires ongoing monitoring and updating as technologies change and efforts to overcome security measures become more sophisticated, and such systems, controls and processes may not be successful in preventing a breach or other incident. Any such security incident could compromise our networks and the information stored there could be accessed, publicly disclosed, encrypted, lost or stolen. We could be required to expend significant amounts of money and other resources to repair or replace information systems or networks. In addition, our liability insurance may not be sufficient in type or amount to cover us against claims related to security breaches, cyber-attacks and other related security incidents.

The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing amount of focus on privacy and data protection issues with the potential to affect our business, including compliance with the Health Insurance Portability and Accountability Act of 1996 and state laws requiring security breach notification. The collection and use of personal health data of individuals in the European Union is also governed by strict data protection laws. In addition to existing laws, since May 25, 2018, the General Data Protection Regulation (GDPR) has imposed obligations with respect to European Union data and substantial fines for breaches of the data protection rules. The GDPR increased our responsibility and potential liability in relation to personal data that we process, and we were required to implement additional mechanisms to comply with the GDPR and related European Union data protection rules. Enforcement uncertainty and the costs associated with ensuring GDPR compliance may be onerous and adversely affect our business, operating results, prospects and financial condition.

We continue to evaluate the legal issues that arise concerning transfer of personal data of residents of the European Economic Area (EEA) member states or the U.K. to the U.S. or other jurisdictions that are not deemed adequate by the European Commission. Among other steps, we are implementing the new standard contractual clauses issued on June 4, 2021 by the European Commission. It remains uncertain how these standard contractual clauses will be implemented by the data exporters and data importers and whether they will ultimately be deemed sufficient by European courts. MEI Pharma observes the developments and will agree to the appropriate data transfer mechanism. In addition to standard contractual clauses, we may rely on individual contents of the patients where appropriate and necessary to safeguard the data flow from the EU to the U.S. Present solutions to legitimize transfers of personal data from the EEA may be challenged or deemed insufficient. We may, in addition to other impacts, experience additional costs associated with increased compliance burdens, and we and our customers face the potential for regulators in the EEA or U.K. to apply different standards to the transfer of personal data from the EEA/U.K. to the U.S., and to block, or require ad hoc verification of measures taken with respect to, certain data flows from the EEA or U.K. to the U.S. We also may be required to engage in new contract negotiations with third parties that aid in processing data on our behalf. We may experience reluctance or refusal by current or

---

prospective European clinical trial sites and CROs to use our products, and we may find it necessary or desirable to make further changes to our processing of personal data of EEA or U.K. data subjects.

Additionally, California has the California Consumer Privacy Act (CCPA), which creates individual privacy rights for consumers (as that word is broadly defined in the law) and places increased privacy and security obligations on entities handling personal data of consumers or households. The CCPA may significantly impact our business activities and require substantial compliance costs that adversely affect business, operating results, prospects and financial condition. Amendments to the CCPA mandated by the California Privacy Rights Act (CPRA) will impose additional privacy requirements, effective on January 1, 2023. Similarly comprehensive state consumer privacy laws in other states, such as Virginia, Utah, Connecticut and Colorado will also become effective in 2023. These new state privacy measures may reflect the start of a movement in other state legislatures to enact more comprehensive privacy laws, which would create a more complex privacy regulatory landscape for our business in the U.S. In addition, there is privacy legislation and rule making efforts at the federal level which may increase our privacy obligations in the U.S.

Thus, any access, disclosure or other loss of information, including our data being breached at our partners or third-party providers, along with violations of privacy laws that exist and are increasing around the world, could result in legal claims or proceedings and liability under laws that protect the privacy of personal information, disrupt our operations and damage our reputation, which could adversely affect our business.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could harm our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. From time to time and in the future, our operations may involve the use of hazardous and flammable materials, including chemicals and biological materials, and may also produce hazardous waste. Even if we contract with third parties for the disposal of these materials and waste, we cannot completely eliminate the risk of contamination or injury resulting from these materials. In the event of contamination or injury resulting from the use or disposal of our hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations.

We maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, but this insurance may not provide adequate coverage against potential liabilities. However, we do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. Current or future environmental laws and regulations may impair our research, development or production efforts. In addition, failure to comply with these laws and regulations may result in substantial fines, penalties or other sanctions.

We or the third parties upon whom we depend may be adversely affected by natural disasters and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Events outside of our control, including natural disasters and public health emergencies, could severely disrupt our operations and have a material adverse effect on our business, operating results, prospects or financial condition. If a natural disaster, or public health emergency such as COVID-19, power outage or other event occurred that prevented us from conducting our clinical trials, including by damaging our critical infrastructure, such as third-party facilities, or that otherwise disrupted operations and travel, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. If a natural disaster, or public health emergency such as COVID-19, power outage or other event occurred that prevented us from conducting our clinical trials, including by damaging our critical infrastructure, such as third party facilities, or that otherwise disrupted operations and travel, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. The disaster recovery and business continuity plans we have in place may prove inadequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business, operating results, prospects or financial condition.

Limitations on the deductibility of net operating losses could adversely affect our business and financial condition.

We have a history of net operating losses. In December 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the Tax Act). The Tax Act limits the deduction of net operating losses to 80% of current year taxable income. The limitations on the net operating loss deduction, as well other changes in tax policy, may subject us to additional taxation, adversely affecting our results of operations and financial condition.

Risks Related to Securities Markets and Investment in our Stock

We are currently operating in a period of capital markets disruption and economic uncertainty.

The U.S. capital markets are currently experiencing extreme volatility and disruption following the global outbreak of COVID-19, high inflation and the government response thereto, potential economic downturn, publicized failures in the regional banking

---

sector, the war in Ukraine, the upcoming U.S. presidential election, and other global events. Disruptions in the capital markets in the past have resulted in illiquidity in parts of the capital markets. Future market disruptions and/or illiquidity would be expected to have an adverse effect on our business, financial condition, results of operations and cash flows. Unfavorable economic conditions also would be expected to increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us should that become required for us to fund ongoing operations. These events have limited and could continue to limit our capital investment considerations, limit our ability to fund further clinical development, limit our ability to identify and implement any potential strategic alternatives and have a material negative impact on our operating results.

If we fail to comply with the continued listing standards of the Nasdaq Capital Market, we may be delisted and the price of our common stock, our ability to access the capital markets and our financial condition could be negatively impacted.

Our common stock is currently listed on Nasdaq under the symbol MEIP. To maintain the listing of our common stock on the Nasdaq Capital Market, we are required to meet certain listing requirements, including, among others, maintaining a minimum closing bid price of $1.00 per share. As we continue to explore strategic alternatives, we intend to actively monitor the bid price of our common stock and its compliance with the listing requirement. If we fail to comply with the continued listing standards and the Nasdaq Capital Market delists our securities from trading on its exchange, we and our stockholders could face significant negative consequences including: reducing the liquidity and market price of our common stock; reducing the number of investors willing to hold or acquire our common stock, which could negatively impact our ability to raise equity financing; decreasing the amount of news and analyst coverage of us; and limiting our ability to issue additional securities or obtain additional financing in the future. In addition, delisting from Nasdaq may negatively impact our reputation and, consequently, our business.

Our business could be negatively impacted as a result of any future activism campaigns by Anson Advisors Inc. Anson Advisors Inc. and Cable Car Capital LLC and other activist investors.

Anson Advisors Inc. holds approximately 16.4% of our outstanding common stock and Cable Car Capital LLC holds approximately 9.2% of our outstanding common stock, and each have sought to exert influence on our business operations and Board, and we expect that each will or may continue to do so. holds approximately 13.0% of our outstanding common stock and Cable Car Capital LLC holds approximately 6.9% of our outstanding common stock, and each have sought to exert influence on our business operations and Board of Directors, and we expect that each will or may continue to do so.

In July 2023, Anson Advisors Inc. Anson Advisors Inc. and Cable Car Capital LLC initiated a consent solicitation to seek the consent of our stockholders holding at least a majority of our outstanding shares of common stock to, among other things, remove and replace all members of our Board. On September 18, 2023, we filed our definitive consent revocation statement urging stockholders to revoke their consents and reject the Consent Solicitation.

The Consent Solicitation and our response to it resulted in significant distraction for management and additional capital outlays by us. Continued pursuit or further activities by Anson Advisors Inc. Anson Advisors Inc. and Cable Car Capital LLC, or by other activist shareholders, could result in yet additional distractions and costs and could lead to a materially adverse impact on our business or operating results.

The trading price of the shares of our common stock has been and may continue to be highly volatile and could decline in value and we may incur significant costs from class action litigation.

The trading price of our common stock could be highly volatile in response to various factors, many of which are beyond our control, including, but not limited to, the following:

---

Equity markets in general, and the market for biotechnology and life sciences companies in particular, have experienced substantial price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of companies traded in those markets. In addition, changes in economic conditions in the U.S., the Europe or globally, particularly in the context of current global events, could impact upon our ability to grow profitably. Adverse economic changes are outside our control and may result in material adverse impacts on our business or our results of operations. These broad market and industry factors may materially affect the market price of shares of our common stock, regardless of our development and operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been instituted against that company. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management’s attention and resources.

Future sales of our common stock, including common stock issued upon exercise of outstanding warrants or options, may depress the market price of our common stock and cause stockholders to experience dilution.

The market price of our common stock could decline as a result of sales of substantial amounts of our common stock in the public market, including upon exercise of outstanding warrants or stock options, and any subsequent sales of such shares. As of June 30, 2024, we had outstanding warrants exercisable to purchase 102,513 shares of common stock at an exercise price of $6.80 per share, which expire in October 2027. We also have outstanding options to purchase 1,357,213 shares of common stock . We may seek additional capital through one or more additional equity transactions in the future; however, such transactions will be subject to market conditions and there can be no assurance any such transactions will be completed. If we sell shares in the future, the prices at which we sell these future shares will vary, and these variations may be significant. Stockholders will experience significant dilution if we sell these future shares at prices significantly below the price at which such previous stockholders invested.

Other than as described below or in connection with a strategic transaction we do not intend to pay, and we have not paid, any cash dividends on our shares of common stock. Our stockholders will not be able to receive a return on their shares unless the value of our common stock appreciates and they sell their shares. Therefore, our stockholders will not be able to receive a return on their investment unless the value of our common stock appreciates and they sell their shares.

Other than the Capital Return, we have never paid or declared any cash dividends on our common stock, and we intend to retain any future earnings to finance the development and expansion of our business. We do not anticipate paying any cash dividends on our common stock in the foreseeable future other than in connection with a strategic transaction. We do not anticipate paying any cash dividends on our common stock in the foreseeable future. Therefore, our stockholders will not be able to receive a return on their investment unless a strategic transaction that requires a dividend is successful or the value of our common stock appreciates and they sell their shares. Therefore, our stockholders will not be able to receive a return on their investment unless the value of our common stock appreciates and they sell their shares.

We will have broad discretion over the use of the net proceeds from any exercise of outstanding warrants and options.

We will have broad discretion to use the net proceeds to us upon any exercise of outstanding warrants and options, and investors in our stock will be relying on the judgment of our Board and management regarding the application of these proceeds. Although we expect to use a substantial portion of the net proceeds from any exercise of the warrants and options for general corporate purposes and progression of our clinical trial programs, we have not allocated these net proceeds for specific purposes.

We are authorized to issue blank check preferred stock, which could adversely affect the holders of our common stock.

Our amended and restated certificate of incorporation allows us to issue blank check preferred stock with rights potentially senior to those of our common stock without any further vote or action by the holders of our common stock. The issuance of a class of preferred stock could decrease the amount of earnings and assets available for distribution to the holders of our common stock or could adversely affect the rights and powers, including voting rights, of such holders. The issuance of a class of preferred stock could decrease the amount of earnings and assets available for distribution to the holders of our common stock or 39 Table of Contents could adversely affect the rights and powers, including voting rights, of such holders. In certain circumstances, such issuance could have the effect of decreasing the market price of our shares or making a change in control of the company more difficult.

Anti-takeover provisions contained in our amended and restated certificate of incorporation and sixth amended and restated bylaws, as well as provisions of Delaware law, could impair a takeover attempt.

Our amended and restated certificate of incorporation and sixth amended and restated bylaws contain provisions that may discourage unsolicited takeover proposals that stockholders may consider to be in their best interests. We are also subject to anti-takeover provisions under Delaware law, which could delay or prevent a change of control. Together, these provisions may make more difficult the removal of management and may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities. These provisions include:

---

Our sixth amended and restated bylaws require, to the fullest extent permitted by law, that derivative actions brought in our name, actions against our directors, officers, other employees or stockholders for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel, which may have the effect of discouraging lawsuits against our directors, officers, other employees or stockholders.

Our sixth amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for any stockholder to bring (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of ours to us or our stockholders, (iii) any action asserting a claim pursuant to any provision of the Delaware General Corporation Law, or (iv) any action asserting a claim governed by the internal affairs doctrine, and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel, provided, however, that, in each case, if the Court of Chancery does not have jurisdiction, the forum for such action shall be another state court located within the State of Delaware or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware, in all cases subject to the court having personal jurisdiction over the indispensable parties named as defendants therein.

Any person or entity purchasing or otherwise acquiring or holding any interest in our shares of capital stock shall be deemed to have notice of and consented to such provisions.

Notwithstanding the foregoing, the forum selection provision of our sixth amended and restated bylaws will not apply to suits brought to enforce any liability or duty created by the federal securities laws or any other claim for which the federal district courts of the U.S. of America shall be the sole and exclusive forum.

This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our sixth amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition. Alternatively, if a court were to find the choice of forum provision contained in our fifth amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition.

Our executive officers and directors may sell shares of their stock, and these sales could adversely affect our stock price.

Sales of our stock by our executive officers and directors, or the perception that such sales may occur, could cause the market price of our common stock to decline or could make it more difficult for us to raise funds through the sale of equity in the future, either as part, or outside, of trading plans under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the Exchange Act).

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

We recognize the importance cybersecurity has to the success of our business, as well as recognize the need to continually assess cybersecurity risks and evolve our responses in the face of a rapidly and ever-changing environment. Accordingly, we aim to protect our business operations, records and information against known and evolving cybersecurity threats.

Risk Management and Strategy

We have established policies and processes for assessing, identifying, and managing material risk from cybersecurity threats, and have integrated these processes into our overall risk management systems and processes. We routinely assess material risks from cybersecurity threats, including any potential unauthorized occurrence on or conducted through our information systems that may result in adverse effects on the confidentiality, integrity, or availability of our information systems or any information residing within these systems.

---

We conduct periodic risk assessments to identify cybersecurity threats, as well as assessments in the event of a material change in our business practices that may affect information systems that are vulnerable to such cybersecurity threats. These risk assessments include identification of reasonably foreseeable internal and external risks, the likelihood and potential damage that could result from such risks, and the sufficiency of existing policies, procedures, systems, and safeguards in place to manage such risks.

Following these risk assessments, we re-design, implement, and maintain reasonable safeguards to minimize identified risks, reasonably address any identified gaps in existing safeguards, and regularly monitor the effectiveness of our safeguards. Primary responsibility for assessing, monitoring and managing our cybersecurity risks rests with the Vice President of Information Technology who reports to our Acting Chief Executive Officer, Chief Financial Officer to manage the risk assessment and mitigation process.

As part of our overall risk management system, we monitor and test our safeguards and train our employees on these safeguards, in collaboration with our Information Technology department. Personnel at all levels and departments are made aware of our cybersecurity policies through trainings and internal communications.

If required, we engage consultants, or other third parties in connection with our risk assessment processes. These service providers, where appropriate, assist us in the assessment, testing or other aspects of our security controls to help identify material cybersecurity risks to our critical systems, information, products, services, and our broader enterprise IT environment, as well as assist us in designing and implementing our cybersecurity policies and procedures.

We have not encountered cybersecurity challenges that have materially impaired our operations or financial standing. For additional information regarding risks from cybersecurity threats, please refer to Item 1A, “Risk Factors,” in this annual report on Form 10-K.

Cybersecurity Governance

Our Board considers cybersecurity risk as part of its risk oversight function and has delegated oversight of cybersecurity and other information technology risks to the Audit Committee. The Audit Committee oversees management’s implementation of our cybersecurity risk management program and is responsible for monitoring and assessing strategic risk exposure, while our management team is responsible for the day-to-day operations over the material risks we face. Our management team, including our Acting Chief Executive Officer, Chief Financial Officer and Vice President of Information Technology, provide periodic briefings to the Audit Committee regarding our cybersecurity risks and activities, including any recent cybersecurity incidents and related responses, if applicable.

The Audit Committee receives annual reports from management on our cybersecurity risks. In addition, management updates the Audit Committee, as necessary, regarding any material cybersecurity incidents, as well as any incidents with lesser impact potential.

The Audit Committee reports to the full Board regarding its activities, including those related to cybersecurity. The full Board also receives briefings from management on our cyber risk management program, in the discretion of the Board and management. Board members may receive presentations on cybersecurity topics from external experts as part of the Board’s continuing education on topics that impact public companies.

Our Acting Chief Executive Officer, CFO and Vice President of Information Technology, are responsible for assessing and managing our material risks from cybersecurity threats and have decades of experience in overseeing operations, including information technology functions, in the public company environment. The team has primary responsibility for our overall cybersecurity risk management program and supervises our retained external cybersecurity consultants as needed.

Our management team supervises cybersecurity risk management efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include briefings from external consultants engaged by us; threat intelligence and other information obtained from governmental, public or private sources; and alerts and reports produced by security tools deployed in the IT environment. The cybersecurity risk management program also includes tools and activities to prevent, detect, and analyze current and emerging cybersecurity threats, and plans and strategies to address threats and incidents.
