Overview

We are a late-stage pharmaceutical company committed to the development and commercialization of novel cancer therapies intended to improve outcomes for patients. MEI Pharma's portfolio of drug candidates has three clinical-stage assets, including zandelisib (f/k/a ME-401), currently in multiple ongoing clinical studies intended to support marketing applications with the U.S. Food and Drug Administration ("FDA") and other regulatory authorities globally. Our approach to building our pipeline is to license or acquire promising cancer agents and build value in programs through development, commercialization and strategic partnerships, as appropriate. Our common stock is listed on the Nasdaq Capital Market under the symbol "MEIP."

Clinical Development Programs

We build our pipeline by licensing promising cancer agents and creating value in programs through development, commercialization and strategic partnerships, as appropriate. Our objective is to leverage the mechanisms and properties of our pipeline drug candidates to optimize the balance between efficacy and tolerability to meet the needs of patients with cancer. Our drug candidate pipeline includes:


Zandelisib (f/k/a ME-401), an oral phosphatidylinositol 3-kinase ("PI3K") delta
inhibitor;
•
Voruciclib, an oral cyclin-dependent kinase ("CDK") 9 ("CDK9") inhibitor; and
•
ME-344, a mitochondrial inhibitor targeting the oxidative phosphorylation
("OXPHOS") complex.

Recent Developments

Nasdaq Bid Price Letter

On May 9, 2022, we received a letter from Nasdaq indicating that, for the last thirty consecutive business days, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued listing on the Nasdaq Capital Market.

In accordance with Nasdaq listing rules, we were provided an initial period of 180 calendar days, or until November 7, 2022, to regain compliance. The letter states that Nasdaq will provide written notification that we have achieved compliance with its rules if at any time before November 7, 2022, the bid price of our common stock closes at $1.00 per share or more for a minimum of ten consecutive business days. The Nasdaq letter had no immediate effect on the listing or trading of our common stock, and the common stock continued to trade on The Nasdaq Capital Market.

If we do not regain compliance with Nasdaq listing rules by November 7, 2022, we may be eligible for an additional 180 calendar day compliance period. To qualify, we would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the deficiency during the second compliance period, by effecting a reverse stock split, if necessary. However, if it appears to Nasdaq that we will not be able to cure the deficiency, or if we are otherwise not eligible, Nasdaq would notify us that our securities would be subject to delisting. In the event of such a notification, we may appeal Nasdaq's determination to delist our securities, but there can be no assurance Nasdaq would grant our request for continued listing.

We have not regained compliance with Nasdaq listing rules as of the date of this Annual Report.

Equity Transactions

Underwritten Registered Offering

During the year ended June 30, 2022, we completed an underwritten registered offering of 20,125,000 shares of common stock at a price per share of $2.60 for net cash proceeds of $48.7 million, after offering costs of $3.7 million. During the year ended June 30, 2020, we completed an underwritten registered offering of 32,343,750 shares of common stock at a price per share of $1.60 for net cash proceeds of $48.5 million, after offering costs of $3.3 million.

Shelf Registration Statement

We have a shelf registration statement that permits us to sell, from time to time, up to $200.0 million of common stock, preferred stock and warrants. The shelf registration was filed and declared effective in May 2020, replacing our prior shelf registration statement that was filed and declared effective in May 2017, and carrying forward approximately $107.5 million of unsold securities registered under the prior shelf registration statement. As of June 30, 2022, there was $123.4 million aggregate value of securities available under the shelf registration statement.

At-The-Market Equity Offering

On November 10, 2020, we entered into an At-The-Market Equity Offering Sales Agreement (the "2020 ATM Sales Agreement"), pursuant to which we may sell an aggregate of up to $60.0 million of our common stock pursuant to the shelf registration statement. We had previously entered into an At-The-Market Equity Offering Sales Agreement in November 2017 (the "2017 ATM Sales Agreement"), pursuant to which we could sell an aggregate of up to $30.0 million of our common stock pursuant to the shelf registration statement. The 2017 ATM Sales Agreement expired on November 8, 2020. During the year ended June 30, 2021, we sold 958,083 shares under the 2017 ATM Sales Agreement for net proceeds of $3.1 million, after costs of $0.1 million. There were no sales under the 2020 ATM Sales Agreement during the year ended June 30, 2022. As of June 30, 2022, there was $60.0 million remaining available under the 2020 ATM Sales Agreement.

Warrants

As of June 30, 2022, we had outstanding warrants to purchase 16,058,985 shares of our common stock. The warrants are fully vested, exercisable at a price of $2.54 per share and expire in May 2023. Pursuant to the terms of the warrants, we could be required to settle the warrants in cash in the event of an acquisition of the Company and, as a result, the warrants are required to be measured at fair value and reported as a liability in the Balance Sheets. Therefore, we are required to account for the warrants as liabilities and record them at fair value. The warrants were revalued as of June 30, 2022, 2021 and 2020 at $1.6 million, $22.4 million and $40.5 million, respectively. The changes in fair value were recorded on our Statements of Operations. During the year ended June 30, 2021, a warrant holder completed a cashless exercise of 2,617 warrants for 964 shares of common stock. No warrants were exercised during the years ended June 30, 2022 and 2020.

Critical Accounting Policies and Management Estimates

Management's discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements


                                       45

--------------------------------------------------------------------------------

Table of Contents

requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, expenses and related disclosures. Actual results could differ from those estimates. We believe the following accounting policies to be critical to the judgments and estimates used in the preparation of our financial statements.



Revenue Recognition

Revenues from Customers

We recognize revenue in accordance with Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers ("Topic 606") when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. For enforceable contracts with our customers, we first identify the distinct performance obligations - or accounting units - within the contract. Performance obligations are commitments in a contract to transfer a distinct good or service to the customer.

Payments received under commercial arrangements, such as licensing technology rights, may include non-refundable fees at the inception of the arrangements, cost reimbursements, milestone payments for specific achievements designated in the agreements, and royalties on the sale of products. At the inception of arrangements that include variable consideration, we use judgment to estimate the amount of variable consideration to include in the transaction price using the most likely method. If it is probable that a significant revenue reversal will not occur, the estimated amount is included in the transaction price. Milestone payments that are not within our or the licensee's control, such as regulatory approvals, are not included in the transaction price until those approvals are received. At the end of each reporting period, we re-evaluate estimated variable consideration included in the transaction price and any related constraint and, as necessary, we adjust our estimate of the overall transaction price.

We develop estimates of the stand-alone selling price for each distinct performance obligation. Variable consideration that relates specifically to our efforts to satisfy specific performance obligations is allocated entirely to those performance obligations. Other components of the transaction price are allocated based on the relative stand-alone selling price, over which management has applied significant judgment. We develop assumptions that require judgment to determine the stand-alone selling price for license-related performance obligations, which may include forecasted revenues, development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical, regulatory and commercial success. We estimate stand-alone selling price for research and development performance obligations by forecasting the expected costs of satisfying a performance obligation plus an appropriate margin.

In the case of a license that is a distinct performance obligation, we recognize revenue allocated to the license from non-refundable, up-front fees at the point in time when the license is transferred to the licensee and the licensee can use and benefit from the license. For licenses that are bundled with other distinct or combined obligations, we use judgment to assess the nature of the performance obligation to determine whether the performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. If the performance obligation is satisfied over time, we evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. Revenue is recorded proportionally as costs are incurred. We generally use the cost-to-cost measure of progress because it best depicts the transfer of control to the customer which occurs as we incur costs. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation (an "input method" under Topic 606). We use judgment to estimate the total cost expected to complete the research and development performance obligations, which include subcontractors' costs, labor, materials, other direct costs and an allocation of indirect costs. We evaluate these cost estimates and the progress each reporting period and, as necessary, we adjust the measure of progress and related revenue recognition.

Revenues from Collaborators

At contract inception, we assess whether the collaboration arrangements are within the scope of ASC Topic 808, Collaborative Arrangements ("Topic 808") to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. This assessment is performed based on the responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of Topic 808 that contain multiple units of account, we first determine which units of account within the arrangement are within the scope of Topic 808 and which elements are within the scope of Topic 606. For units of account within collaboration arrangements that are accounted for pursuant to Topic 808, an appropriate recognition method is determined and applied consistently, by analogy to authoritative accounting literature. For units of account within collaboration arrangements that are accounted for pursuant to Topic 606, we recognize revenue as discussed above. Consideration received that does not meet the requirements to satisfy Topic 606 revenue recognition criteria is recorded as deferred revenue on the Balance Sheets, classified as either current or long-term deferred revenue based on our best estimate of when such amounts will be recognized.

Research and Development Costs

Research and development costs are expensed as incurred and include costs paid to third party contractors to perform research, conduct clinical trials and develop and manufacture drug materials. Clinical trial costs, including costs associated with third party contractors, are a significant component of research and development expenses. We expense research and development costs based on work performed. In determining the amount to expense, management relies on estimates of total costs based on contract components completed, the enrollment of subjects, the completion of trials, and other events. Costs incurred related to the purchase or licensing of in-process research and development for early-stage products or products that are not commercially viable and ready for use, or have no alternative future use, are charged to expense in the period incurred.

Share-Based Compensation

Share-based compensation expense stock options and restricted stock units, ("RSUs"), granted to employees and directors is recognized in the Statements of Operations based on estimated amounts. For stock options, we estimate the grant date fair value using a Black-Scholes valuation model, which requires the use of multiple subjective inputs including estimated future volatility, expected forfeitures and the expected term of the awards. We estimate the expected future volatility based on the stock's historical price volatility. The stock's future volatility may differ from the estimated volatility at the grant date. For RSUs, we estimate the grant date fair value using our closing stock price on the date of grant. We recognize the effect of forfeitures in share-based compensation expense when the forfeitures occur. We recognize the value of the awards over the awards' requisite service or performance periods. The requisite service period is generally the time over which our share-based awards vest.

Warrant Liability

Pursuant to the terms of the warrants, we could be required to settle our warrants in cash in the event of an acquisition of the Company and, as a result, the warrants are required to be measured at fair value and reported as a liability in the Balance Sheets. We recorded the fair value of the warrants upon issuance using the Black-Scholes valuation model, and are required to revalue the warrants at each reporting date with any changes in fair value recorded on our Statements of Operations. Inputs used to determine the estimated fair value of the warrant liabilities include the estimated fair value of the underlying stock at the valuation date, the estimated term of the warrants, risk-free interest rates, expected dividends and the expected volatility of the underlying stock.

Leases

At the inception of a leasing arrangement, we determine whether the arrangement is or contains a lease based on the unique facts and circumstances within the arrangement. A lease is identified where an arrangement conveys the right to control the use of identified property, plant, and equipment for a period of time in exchange for consideration. Leases which are identified within the scope of ASC 842 and which have a term greater than one year are recognized on our Balance Sheets as ROU assets and operating lease liabilities. Operating lease liabilities and their corresponding ROU assets are recorded based on the present value of lease payments over the expected remaining lease term. The lease term includes any renewal options and termination options that we are reasonably certain to exercise. Certain adjustments to the ROU asset may be required for items such as initial direct costs paid or incentives received. The present value of lease payments is determined by using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, we use our incremental borrowing rate. The interest rate implicit in lease contracts to calculate the present value is typically not readily determinable. As such, significant management judgment is required to estimate the incremental borrowing rate.

Income Taxes

Our income tax expense consists of current and deferred income tax expense or benefit. Current income tax expense or benefit is the amount of income taxes expected to be payable or refundable for the current year. A deferred income tax asset or liability is recognized for the future tax consequences attributable to tax credits and loss carryforwards and to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of June 30, 2022 and 2021, we have established a valuation allowance to fully reserve our net deferred tax assets. Changes in our ownership may limit the amount of net operating loss carryforwards that can be utilized in the future to offset taxable income.

Results of Operations

Comparison of Years Ended June 30, 2022 and 2021

Revenue: Revenue increased by $5.9 million primarily due to increased reimbursement of expenses from KKC due to research and development activity related to zandelisib.

Total research and development expenses $ 85,641 $ 69,398

Research and development expenses consist primarily of clinical trial costs, including payments to contract research organizations, pre-clinical study costs, and costs to manufacture our drug candidates for non-clinical and clinical studies. Other research and development expenses consist primarily of salaries and personnel costs, share-based compensation, legal costs, and other costs not allocated to specific drug programs. Costs related to zandelisib increased for the year ended June 30, 2022 primarily as a result of higher professional services and drug manufacturing costs offset by decreased costs for the COASTAL study as a result of higher start-up costs during the prior year. Costs related to voruciclib increased for the year ended June 30, 2022 compared with the year ended June 30, 2021 primarily due to increased costs associated with the Phase 1 study and drug manufacturing costs. Cost related to ME-344 increased for the year ended June 30, 2022 compared with the year ended June 30, 2021 primarily due to increased drug manufacturing costs and start-up costs for the Phase 2 study. Other research and development costs increased for the year ended June 30, 2022 compared with the year ended June 30, 2021 primarily due to higher levels of personnel costs associated with increased headcount to support our clinical activities.

General and Administrative: The increase in general and administrative expenses of $6.1 million was primarily due to increases in personnel costs of $2.5 million, external professional services of $2.0 million and corporate overhead costs of $1.6 million.

Other Income, Net: Other income, net, increased by $1.9 million was primarily due to the increase in non-cash gains of $2.6 million related to the changes in the fair value of our warrant liability for warrants issued in connection with our private placement of shares of common stock, primarily as a result of changes in our stock price. Interest and dividend income decreased by $0.2 million for the year ended June 30, 2022 as compared to the year ended June 30, 2021 due to lower average short-term investment balances during the year ended June 30, 2022 as compared to the year ended June 30, 2021.

Comparison of Years Ended June 30, 2021 and 2020

We have omitted discussion of the results of operations for the fiscal year ended June 30, 2020 because it would be redundant to the discussion previously included in Part II, Item 7 of our Annual Report on Form 10-K/A for the fiscal year ended June 30, 2021, filed with the SEC on May 23, 2022.

New Accounting Pronouncements

See Note 1, "The Company and Summary of Significant Accounting Policies," to the Financial Statements included in Item 8 of this Annual Report.

Liquidity and Capital Resources

We have accumulated losses of $374.2 million since inception and expect to incur operating losses and generate negative cash flows from operations for the foreseeable future. As of June 30, 2022, we had $153.3 million in cash, cash equivalents and short-term investments. We believe that these resources will be sufficient to fund our operations for at least 12 months from the issuance of this Annual Report. Our current business operations are focused on continuing the clinical development of our drug candidates. Changes to our research and development plans or other changes affecting our operating expenses may affect actual future use of existing cash resources. Our research and development expenses are expected to increase in the foreseeable future. We cannot determine with certainty costs associated with ongoing and future clinical trials or the regulatory approval process. The duration, costs and timing associated with the development of our product candidates will depend on a variety of factors, including uncertainties associated with the results of our clinical trials.

To date, we have obtained cash and funded our operations primarily through equity financings and license agreements. In order to continue the development of our drug candidates, at some point in the future we expect to pursue one or more capital transactions, whether through the sale of equity securities, debt financing, license agreements or entry into strategic partnerships. There can be no assurance that we will be able to continue to raise additional capital in the future.

Sources and Uses of Our Cash

Net cash used in operating activities for the year ended June 30, 2022 was $48.7 million ($68.7 million, net of $20.0 million of milestone payments received from KKC) compared to $32.0 million ($52.4 million, net of $20.4 million received from the Japanese government for tax

withholdings) for the year ended June 30, 2021. The increase in net cash used in operating activities was due to increased research and development and general and administrative activities as well as other changes in working capital. Net cash provided by operating activities for the year ended June 30, 2020 was $34.3 million ($45.3 million, net of a $79.6 million license fee received from KKC).

Net cash provided by investing activities for the year ended June 30, 2022 was $6.9 million compared to $24.7 million for the year ended June 30, 2021. The decrease in net cash provided by investing activities was primarily due to lower maturities and purchases of short-term investments during the year ended June 30, 2022.

Net cash provided by financing activities for the year ended June 30, 2022 was $49.1 million compared to $3.5 million for the year ended June 30, 2021. Cash raised during the years ended June 30, 2022 and 2021 included $48.7 million and $3.1 million, respectively, of net proceeds from the issuance of common stock.

Contractual Obligations

We have contracted with various consultants and third parties to assist us in pre-clinical research and development and clinical trials work for our leading drug compounds. The contracts are terminable at any time, but obligate us to reimburse the providers for any time or costs incurred through the date of termination. Additionally, we have employment agreements with certain of our current employees that provide for severance payments and accelerated vesting for share-based awards if their employment is terminated under specified circumstances.

In July 2020, we entered into a lease agreement (the "Initial Lease Agreement") for approximately 32,800 square feet of office space in San Diego, California. The Initial Lease Agreement was extended to November 2029 in accordance with the amended lease agreement that we entered into in January 2022 (the "Amended Lease Agreement"). The Amended Lease Agreement also provides for an additional 12,300 square feet of office space adjacent to our current office in San Diego, California and encompasses both our current office space and the additional office space, for a total of approximately 45,100 square feet, which began on July 1, 2022. The average annual lease payment under the Initial and Amended Lease Agreements is approximately $2.5 million, plus a pro rata share of certain building expenses. Our total contractual obligation over the remaining term of the Initial and Amended Lease Agreements is approximately $18.6 million.

Presage License Agreement

In September 2017, we entered into the Presage License Agreement. Under the terms of the Presage License Agreement, Presage granted to us exclusive worldwide rights to develop, manufacture and commercialize voruciclib, a clinical-stage, oral and selective CDK inhibitor, and related compounds. In exchange, we paid Presage $2.9 million. With respect to the first indication, an incremental $2.0 million payment, due upon dosing the first subject in the first registration trial will be owed to Presage, for total payments of $4.9 million prior to receipt of marketing approval of the first indication in the U.S., EU or Japan. Additional potential payments of up to $179 million will be due upon the achievement of certain development, regulatory and commercial milestones. We will also pay mid-single-digit tiered royalties on the net sales of any product successfully developed. As an alternative to milestone and royalty payments related to countries in which we sublicense product rights, we will pay to Presage a tiered percent (which decreases as product development progresses) of amounts received from such sublicensees. As of June 30, 2022, we had not accrued any amounts for potential future payments.

COVID-19

As a result of the ongoing COVID-19 pandemic, various public health orders and guidance measures have been implemented across much of the U.S., and across the globe, including in the locations of our office, clinical trial sites, key vendors and partners. Despite the relaxation of many governmental orders earlier this year, COVID-19 still impacts the normal conduct of business. Furthermore, the COVID-19 virus may continue to mutate into different strains, which could be more contagious or severe or for which current vaccines and treatments are not effective or available.

While we continue to enroll and dose patients in our clinical trials, our clinical development program timelines may continue to be subject to potential negative impacts from the ongoing pandemic in the U.S. and globally. The extent to which the ongoing pandemic continues to impact our business, including our preclinical studies, CMC studies, manufacturing, and clinical trials, will depend on future developments, which are highly uncertain and cannot be predicted with confidence.

We may experience enrollment delays and suspensions, patient withdrawals, postponement of planned clinical or preclinical studies, redirection of site resources from studies, and study deviations or noncompliance. We may also need to maintain or implement study modifications, suspensions, or terminations, the introduction of additional remote study procedures and modified informed consent procedures, study site changes, direct delivery of investigational products to patient homes or alternative sites, which may require state licensing, and changes or delays in site monitoring. The foregoing may require that we consult with relevant review and ethics committees, IRBs and the FDA. The foregoing may also impact the integrity of our study data. The ongoing COVID-19 pandemic may further increase the need for clinical trial patient monitoring and regulatory reporting of adverse effects, and may delay regulatory authority meetings, inspections, assessments, or the regulatory review of marketing or investigational applications or submissions.

The ongoing COVID-19 pandemic may also impact our ability to procure the necessary supply of our investigational drug products, as well as any ancillary supplies necessary for the conduct of our studies. Third party manufacturers may also need to implement measures and changes, or deviate from typical manufacturing requirements that may otherwise adversely impact our product candidates.

In light of the ongoing COVID-19 pandemic, the FDA issued a number of new guidance documents. Specifically, as a result of the potential effect of the ongoing COVID-19 pandemic on many clinical trial programs in the U.S. and globally, the FDA issued guidance concerning potential impacts on clinical trial programs, which guidance FDA has continually updated. In addition, the European Medicines Agency ("EMA") as well as various country regulatory authorities (EU and UK) have issued similar guidance. We have adapted the FDA and EMA/UK guidance for study procedures, data collection, and oversight resulting from the ongoing COVID-19 pandemic.
