2. Summary of Significant Accounting Policies

There have been no material changes to our significant accounting policies from those described in the notes to our audited condensed consolidated financial statements contained in the 2023 Annual Report.

Risks and Uncertainties

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts ~~reported in~~of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and ~~disclosures made~~the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to the valuation of share-based awards, the discount rate used in estimating the ~~accompanying notes~~present value of the right-of-use assets and lease liabilities, clinical trial accruals and the assessment of our ability to fund our operations for at least the next 12 months from the date of issuance of these condensed consolidated financial statements. We ~~use~~base our estimates on historical experience and other market-specific or other relevant assumptions that ~~affect~~we believe to be reasonable under the ~~reported amounts (including assets, liabilities, revenues~~circumstances. Estimates are assessed each reporting period and ~~expenses)~~updated to reflect current information. As future events and ~~related disclosures. Actual~~their effects cannot be determined with precision, actual results ~~could~~may materially differ from those ~~estimates.~~estimates or assumptions.

Segment Reporting

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by our chief operating decision-maker (CODM), our Chief Executive Officer, in making decisions regarding resource allocation and assessing performance. The CODM views its operations and manages its business in one operating segment.

Concentrations of Credit Risk

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash, cash equivalents and short-term investments. Deposits in our checking and money market accounts are maintained in federally insured financial institutions and are subject to federally insured limits or limits set by the Securities Investor Protection Corporation.

We attempt to minimize credit risk associated with our cash, cash equivalents and short-term investments by periodically evaluating the credit quality of our primary financial institutions. Our investment portfolio is maintained in accordance with our investment policy, which is designed to preserve capital, safeguard funds and limit exposure to risk. While we maintain cash deposits in Federal Deposit Insurance Corporation insured financial institutions in excess of federally insured limits, we do not believe that we are exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. We have not experienced any losses on such accounts.

~~Fair Value Measurements~~Short-term Investments

~~Fair value is defined~~Short-term investments are marketable securities with original maturities greater than three months but less than one year from date of purchase. As of December 31, 2023 and June 30, 2023, our short-term investments consisted of $54.3 million and $83.8 million, respectively, in United States government securities. The short-term investments held as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of ~~observable inputs~~December 31, 2023 and ~~minimize the use of unobservable inputs. The fair value hierarchy based on three levels of inputs, of which the first two~~June 30, 2023 are considered ~~observable~~to be held to maturity and are carried at amortized cost. As of December 31, 2023 and June 30, 2023, the ~~last unobservable, that may~~gross unrealized gains and losses were immaterial.

Dividends

Due to our history of net losses, we have elected to first reduce our additional paid-in capital (APIC) to zero by the amount of dividends/return of capital approved by our Board. Any dividends/return of capital approved by our Board, in excess of our APIC, if any, will be ~~used~~recorded as an adjustment to ~~measure fair value is as follows:~~our accumulated deficit.

•

~~Level 1 – Observable inputs such as quoted prices in active markets for identical assets or liabilities.~~

•

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•

~~Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.~~

Revenue Recognition

Revenues from Customers

In accordance with ~~Accounting Standards Codification ("ASC")~~ASC Topic 606, Revenue from Contracts with Customers~~("Topic 606"),~~ (Topic 606), we recognize revenue 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, milestone payments for specific achievements designated in the agreements, and royalties on the sale of products. At the inception of arrangements that include milestone payments, we use judgment to evaluate whether the milestones are probable of being achieved, and we estimate the amount, if any, 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 the probability of achievement of development milestones and any related constraint and, as necessary, we adjust our estimate of the overall transaction price.

We may enter into arrangements that consist of multiple performance obligations. Such arrangements may include any combination of our deliverables. To the extent a contract includes multiple promised deliverables, we apply judgment to determine whether promised deliverables are capable of being distinct and are distinct inwithin the context of the contract. If these criteria are not met, the promised deliverables are accounted for as a combined performance obligation. For arrangements with multiple distinct performance obligations, we allocate variable consideration related to our 50-50 cost share for development services directly to the associated performance obligation and then allocate the remaining consideration among the performance obligations based on their relative stand-alone selling price.

Stand-alone selling price is the price at which we would sell a promised good or service separately to the customer. When not directly observable, we typically estimate 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.

Table of Contents

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”~~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.

For arrangements that include sales-based or usage-based royalties, we recognize revenue at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, we have not recognized any sales-based or usage-based royalty revenue from license agreements.

In connection with our April 2020 Kyowa Kirin Co., Ltd.(KKC) License, Development and Commercialization Agreement (the ~~"Kyowa Kirin~~KKC Commercialization ~~Agreement") with Kyowa Kirin,~~Agreement) described in Note 7. License Agreements, we ~~perform~~performed development services related to our 50-50 cost sharing arrangement for which revenue iswas recognized over time. Additionally, from time to time, we ~~perform~~performed services for ~~Kyowa Kirin~~KKC at their request, the costs of which ~~are~~were fully reimbursed to us. We ~~record~~recorded the reimbursement for such ~~pass through~~pass-through services as revenue at 100% of reimbursed costs, as control of the additional services for ~~Kyowa Kirin is~~KKC was transferred at the time we ~~incur~~incurred such costs. The costs of these services are recognized in the ~~Condensed Consolidated Statements~~condensed consolidated statements of ~~Operations~~operations as research and development expense.

The timing of revenue recognition, invoicing and cash collections results in billed accounts receivable and unbilled receivables (contract assets) and deferred revenue (contract liabilities). We invoice our customers in accordance with agreed-upon contractual terms, typically at periodic intervals or upon achievement of contractual milestones. Invoicing may occur subsequent to revenue recognition, resulting in unbilled receivables. We may receive advance payments from our customers before revenue is recognized, resulting in contract liabilities. The unbilled receivables and deferred revenue reported on the ~~Condensed Consolidated Balance Sheets relate~~condensed consolidated balance sheets related to the ~~Kyowa Kirin~~KKC Commercialization Agreement.

~~As of March 31, 2023 and June 30, 2022, we had $66.1~~ ~~million and $95.4~~ ~~million, respectively, of deferred revenue associated with the Kyowa Kirin Commercialization Agreement, of which $64.5~~ ~~million relates to the U.S. license which is a unit of account under the scope of ASC Topic 808,~~ ~~Collaborative Arrangements~~ ~~("Topic 808") and is not a performance obligation under Topic 606. The remaining balance of deferred revenue as of March 31, 2023 and June 30, 2022 of $1.6~~ ~~million and $30.9~~ million, respectively, relates to the development services performance obligations which are under the scope of Topic 606. The decrease in deferred revenue comes as a result of our winding down of all zandelisib studies outside of Japan. We updated our estimated costs to complete each of the performance obligations, resulting in a higher progress towards completion based on the ratio of costs incurred to date to the total estimated costs. Additionally, during the three months ended December 31, 2022, we recognized revenue related to non-refundable payments for performance obligations that have not commenced and will no longer be initiated.

Our contract liabilities accounted for under Topic 606 relate to the amount of initial upfront consideration that was allocated to the development services performance obligations. Contract liabilities are recognized over the duration of the performance obligations based on the costs incurred relative to total expected costs.

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 elements of 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 in the accompanying ~~Condensed Consolidated Balance Sheets,~~condensed consolidated balance sheets, classified as either ~~short-term~~current or long-term deferred revenue based on our best estimate of when such amounts will be recognized.

Net Income (Loss) Per Share

Basic and diluted net income (loss) per share is computed using the weighted-average number of shares of common stock outstanding during the period, less any shares subject to repurchase or forfeiture. There were no shares of common stock subject to repurchase or forfeiture for the three and six months ended December 31, 2023 and 2022. Diluted net income (loss) per share is computed based on the sum of the weighted-average number of common shares and potentially dilutive common shares outstanding during the period determined using the treasury-stock and if-converted methods.

For purposes of the diluted net income (loss) per share calculation for the three and six months ended December 31, 2023, potentially dilutive securities are excluded from the calculation of diluted net income (loss) per share because their weighted-average exercise prices were above our weighted-average share price as of December 31, 2023; therefore, basic and diluted net income (loss) per share were the same for the three and six months ended December 31, 2023. For purposes of the diluted net income (loss) per share calculation for the three and six months ended December 31, 2022, potentially dilutive securities are excluded from the calculation of diluted net income (loss) per share because their effect would be anti-dilutive and, therefore, basic and diluted net income (loss) per share were the same for the three and six months ended December 31, 2022.

~~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.

~~Leases~~The following table presents potentially dilutive shares excluded from the calculation of diluted net income (loss) per share (in thousands):

~~We account for our leases under ASC Topic 842,~~ ~~Leases~~ (“Topic 842”). Leases which are identified within the scope of Topic 842 and which have a term greater than one year are recognized on our Condensed Consolidated Balance Sheets as right-of-use ("ROU") assets and 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 right-of-use 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 incremental borrowing rate is determined based on the rate of interest that we would pay to borrow on a collateralized basis an amount equal to the lease payments for a similar term and in a similar economic environment. 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.

Operating lease expense for operating leases is recognized on a straight-line basis over the lease term based on the total lease payments. We have elected the practical expedient to not separate lease and non-lease components for our real estate leases. Our non-lease components are primarily related to property maintenance, which varies based on future outcomes, and thus is recognized in operating lease expense when incurred.

~~Share-Based Compensation~~

Share-based compensation expense stock options and restricted stock units ("RSUs") granted to employees and directors is recognized in the Condensed Consolidated Statements of Operations based on estimated amounts. The cost of stock options is measured at the grant date, based on the estimated fair value of the stock option using the Black-Scholes valuation model, which incorporates various assumptions, including expected volatility, risk-free interest rate, the expected term of the award and the dividend yield on the underlying stock. Expected volatility is calculated based on the historical volatility of our stock over the expected option life and other appropriate factors. The expected option term is computed using the "simplified" method as permitted under the provisions of ASC Topic 718, ~~Compensation - Stock Compensation~~. We use the simplified method to calculate the expected term of stock options and similar instruments, as we do not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. Risk-free interest rates are calculated based on continuously compounded risk-free rates for the appropriate term. The dividend yield is assumed to be zero as we have never paid or declared any cash dividends and do not intend to do so in the foreseeable future. For RSUs, we estimate the grant date fair value using our closing stock price on the date of grant. The estimated fair value of stock options and RSUs is amortized on a straight-line basis over the requisite service period, adjusted for actual forfeitures at the time they occur. The requisite service period is generally the time over which our share-based awards vest.

~~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 March 31, 2023, we have established a valuation allowance to fully reserve our net deferred tax assets. Tax rate changes are reflected in income during the period such changes are enacted. Changes in our ownership may limit the amount of net operating loss carryforwards that can be utilized in the future to offset taxable income.

~~There have been~~ no material changes in our unrecognized tax benefits since June 30, 2022, and, as such, the disclosures included in our 2022 Annual Report continue to be relevant for the nine months ended March 31, 2023.

Recent Accounting Pronouncement

Recently Adopted

In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-13, Financial Instruments–Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments~~("ASU 2016-13")~~ (ASU 2016-13), as amended. The amendments in ASU 2016-13 require, among other things, financial assets measured at amortized cost basis to be presented at the net amount expected to be collected as compared to previous U.S. GAAP which delayed recognition until it was probable a loss had been incurred. The amendments in ASU 2016-13 are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. ~~We are currently evaluating the impact that~~The adoption of ASU 2016-13 ~~will~~did not have a material impact on our financial statements and related disclosures.

We do not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on our condensed consolidated financial position, results of operations and cash flows.

Recently Issued

From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted as of the specified effective date. We believe the impact of recently issued standards, other than those noted below, and any issued but not yet effective standards will not have a material impact on its condensed consolidated financial statements upon adoption.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker. This ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. A public entity should apply the amendments in this ASU retrospectively to all prior periods presented in the financial statements. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows and financial condition.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid. ASU No. 2023-09 requires a public business entity (PBE) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity may apply the amendments in this ASU prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods, or may apply the amendments retrospectively by providing the revised disclosures for all period presented. We expect this ASU to only impact our disclosures with no impacts to our results of operations, cash flows, and financial condition.

4. Fair Value Measurements

The carrying amounts of financial instruments such as cash equivalents, short-term investments and accounts payable approximate the related fair values due to the short-term maturities of these instruments. We invest our excess cash in financial instruments which are readily convertible into cash, such as money market funds and U.S. government securities. Cash equivalents and short-term investments are ~~measured at fair value on a recurring basis and are~~ classified as Level 1 as defined by the fair value hierarchy. As of December 31, 2023 and June 30, 2023, we had no assets or liabilities measured on a recurring or non-recurring basis.

In May 2018, we issued warrants in connection with ~~our~~a private placement of our shares of common stock.

We recorded the fair value of the warrants upon issuance using the Black-Scholes valuation model and ~~are~~were required to revalue the warrants at each reporting date with any changes in fair value recorded onin our ~~Condensed Consolidated Statement~~condensed consolidated statement of ~~Operations.~~operations through their expiration in May 2023. The valuation of the warrants iswere considered under Level 3 of the fair value hierarchy due to the need to use assumptions in the valuation that ~~are~~were both significant to the fair value measurement and unobservable. Inputs used to determine estimated fair value of the warrant liabilities ~~include~~included 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. The significant unobservable inputs used in the fair value measurement of the warrant liabilities were the volatility rate and the estimated term of the warrants. Generally, increases (decreases) in the fair value of the underlying stock and estimated term would result in a directionally similar impact to the fair value measurement. The change in the fair value of the Level 3 warrant liability is reflected in the ~~Condensed Consolidated Statements~~condensed consolidated statements of ~~Operations~~operations for the three and ~~nine~~six months ended ~~March~~December 31, 2022. During the three months ended December 31, 2023 and ~~2022, respectively.~~the year ended June 30, 2023, there were no transfers into or out of Level 3 of the fair value hierarchy.

~~Note 3. Short-Term Investments~~5. One-time Employee Termination Benefits

In connection with our joint decision to discontinue development of zandelisib outside of Japan, in December 2022, we announced a realignment of our clinical development efforts that streamlined our organization towards the continued clinical development of our two earlier clinical-stage assets, voruciclib and ME-344. As ~~of March~~a result, our Board approved a staggered workforce reduction (the Reduction in Force) affecting 28 employees in December 2022 and an additional 26 employees through June 2023, representing an aggregate 51% Reduction in Force. For the three and six months ended December 31, ~~2023, and June 30,~~ 2022, ~~our short-term investments consisted~~we recorded one-time employee benefits of $~~103.2~~0.8 million and $~~137.5~~0.4 million, within research and development expense and general and administrative expense, respectively, associated with the termination of 18 employees in ~~U.S. government securities.~~ research and development departments and 10 employees in general and administrative departments. For the three months ended December 31, 2023, we recorded additional one-time employee benefits of $141,000 and $168,000, within research and development expense and general and administrative expense, respectively, associated with the termination of two and three additional research and development and general and administrative employees. For the six months ended December 31, 2023, we recorded additional one-time employee termination benefits of $169,000 and $168,000 within research and development expense and general and administrative expense, respectively, associated with the termination of six additional employees, three each within research and development and general and administrative departments.

6. Commitments and Contingencies

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. We also 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.

Litigation

From time to time, we may be involved in various lawsuits, legal proceedings, or claims that arise in the ordinary course of business. Management believes there are no claims or actions pending against us as of ~~March~~December 31, 2023 which will have, individually or in the aggregate, a material adverse effect on its business, liquidity, financial position, or results of operations. Litigation, however, is subject to inherent uncertainties, and ~~June 30, 2022 had maturity dates of less than one year, are considered~~an adverse result in these or other matters may arise from time to ~~be “held to maturity” and are carried at amortized cost.

Indemnification

In accordance with our amended and restated certificate of incorporation and bylaws, we have indemnification obligations to our officers and directors for certain events or occurrences, subject to certain limits, while they are serving in such capacity. There have been no claims to date, and we have a directors and officers liability insurance policy that may enable it to recover a portion of any amounts paid for future claims.

Presage License Agreement

As discussed in Note 8. Other License Agreements, we are party to a license agreement with Presage Biosciences, Inc. (Presage) under which we may be required to make future payments upon the achievement of certain development, regulatory and commercial milestones, as well as potential future royalties based upon net sales. As of December 31, 2023, we had not accrued any amounts for potential future payments as achievement of the milestones had not been met.

Potential Return of Capital

As discussed in Note 1. Description of Business and Basis of Presentation, under certain circumstances, we could potentially be obligated to pay a Potential Second Return of Capital, if authorized by our Board should our ongoing ME-344 Phase 1b trial fail to meet certain defined endpoints or our Board determines not to proceed with a second cohort. The Potential Second Return of Capital may take the form of a dividend or tender offer and is subject to Board approval as well as modification associated with applicable requirements under Delaware law, as detailed in the Cooperation Agreement. As of December 31, 2023, our Board has not declared the Potential Second Return of Capital and, therefore, we have not accrued a liability related to it.

~~Note 4.~~7. License Agreements

Kyowa Kirin Co., Ltd. License, Development and Commercialization Agreement

In April 2020, we entered into the ~~Kyowa Kirin~~KKC Commercialization Agreement ~~under~~pursuant to which we granted to ~~Kyowa Kirin~~KKC a co-exclusive, sublicensable, payment-bearing license under certain patents and know-how controlled by us to develop and commercialize zandelisib and any pharmaceutical product containing zandelisib for all human indications in the U.S. (the ~~"U.S. License")~~U.S. License), and an exclusive (subject to certain retained rights to perform obligations under the ~~Kyowa Kirin~~KKC Commercialization Agreement), sublicensable, payment-bearing, license under certain patents and know-how controlled by us to develop and commercialize zandelisib and any pharmaceutical product containing zandelisib for all human indications in countries outside of the U.S. ~~(the “Ex-U.S." and the “Ex-U.S. License”). Kyowa Kirin~~KKC granted to us a co-exclusive, sublicensable, license under certain patents and know-how controlled by ~~Kyowa Kirin~~KKC to develop and commercialize zandelisib for all human indications in the U.S., and a co-exclusive, sublicensable, royalty-free, fully paid license under certain patents and know-how controlled by ~~Kyowa Kirin~~KKC to perform our obligations in the Ex-U.S. ~~under the Kyowa Kirin Commercialization Agreement. Kyowa Kirin~~KKC also paid us an initial nonrefundable payment of $100.0 million.

Considering the ~~Ex-U.S.~~decisions to discontinue worldwide development of zandelisib the parties entered into a Termination Agreement on July 14, 2023, agreeing to mutually terminate the global KKC Commercialization Agreement. Pursuant to the Termination Agreement, we regained full, global rights to develop, manufacture and commercialize zandelisib, subject to KKC's limited rights to use for compassionate use (as more specifically defined in the Termination Agreement) in certain ~~exceptions, is solely responsible for all costs related thereto. We provide to Kyowa Kirin certain drug supplies necessary~~expanded access programs for the ~~development~~existing patients who have been enrolled in Japanese clinical trials sponsored by KKC until November 30, 2027, and ~~commercialization~~for which KKC is fully liable; each party released the other party from any and all claims or demands arising from the original KKC Commercialization Agreement excluding certain surviving claims; however, we are obligated to deliver a discrete quantity of ~~zandelisib in the Ex-U.S., with the understanding that Kyowa Kirin will assume responsibility for manufacturing for the Ex-U.S. as soon as practicable.~~materials to facilitate KKCs compassionate use activities.

We ~~assessed~~determined the ~~Kyowa Kirin~~KKC Commercialization Agreement in accordance with Topic 808 and Topic 606 and determined that our obligations comprise the U.S. License, the Ex-U.S. License, and development services (the “Development Services”).

See discussion within the

As discussed in Note 1, we and Kyowa Kirin jointly decided to discontinue zandelisib development in the U.S. As of March 31, 2023, we updated our assessment of the total transaction price from the Kyowa Kirin Commercialization Agreement to be $~~217.0~~Revenue Recognition ~~million, comprised~~subsection of ~~the upfront payment~~Note 2. Summary of $Significant Accounting Policies~~100.0~~ ~~million, milestone payments of $20.0~~ ~~million, estimated development cost-sharing of $91.8~~ ~~million, and deferred revenue of $5.2~~ ~~million. As of March 31, 2023, the updated assessment reflects a decrease in estimated variable consideration related to development cost sharing of $143.1~~ million from June 30, 2022. In December 2022, we announced our plan to discontinue the global development of zandelisib outside of Japan. As a result, we decreased our estimate for variable consideration related to development cost sharing. During the three months ended December 31, 2022, we recognized revenue of $~~16.6~~ ~~million from the change in estimate. Additionally, during the three months ended December 31, 2022, we recognized $8.6~~ million of revenue related to non-refundable payments for performance obligations that have not commenced and will no longer be initiated. Any variable consideration related to sales-based royalties and commercial milestones related to licenses of intellectual property will be determined when the sale or usage occurs, and is therefore excluded from the transaction price. In addition, we are eligible to receive future development and regulatory milestones upon the achievement of certain criteria; however, these amounts are excluded from variable consideration as the risk of significant revenue reversal will only be resolved depending on future research and development and/or regulatory approval outcomes. We re-evaluate the estimated variable consideration included in the transaction price and any related constraints at the end of each reporting period.

We allocated the transaction price of the Ex-U.S. License and Development Services performance obligations to each unit of account. Variable consideration that relates specifically to our efforts to satisfy specific performance obligations are 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 developed the estimated stand-alone selling price for the licenses using the risk-adjusted net present values of estimated cash flows, and the estimated stand-alone selling price of the development services performance obligations by estimating costs to be incurred, and an appropriate margin, using an income approach..

We evaluated the Termination Agreement under ASC 606 and determined ~~that control~~it met the requirements of a contract modification which changed the scope of the ~~U.S. License~~KKC Commercialization Agreement, and ~~Ex-U.S. License~~the remaining goods and services associated with the wind-down activities to be transferred. The cost of satisfying our performance obligation to provide compassionate use supply to KKC was determined to be de minimis and, therefore, immaterial within the context of the KKC Commercialization Agreement. As of September 30, 2023 activities associated with the compassionate use supply were ~~transferred~~completed.

Table of Contents

With the execution of the Termination Agreement, we regained full, global rights (subject to ~~Kyowa Kirin during~~KKC's limited rights for compassionate use) and KKC has no further rights to develop, use or commercialize zandelisib in the ~~year ended~~U.S., nor do we have any remaining performance obligations. All consideration received from KKC was nonrefundable, therefore, the remaining long-term deferred revenue as of June 30, ~~2020, and recognized revenue~~2023, of $~~21.0~~ ~~million related to the Ex-U.S. License.

8. Other License Agreements

Presage License Agreement

In September 2017, we, as licensee, entered into a ~~license agreement~~License Agreement with ~~Presage Biosciences, Inc. (“Presage”).~~Presage. Under the terms of ~~such~~the license agreement, ~~(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 $2.9 ~~million.~~million to Presage. With respect to the first indication, an incremental $2.0 million payment, due upon dosing of 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., ~~E.U.~~EU or Japan. Additional potential payments of up to $~~179~~179.0 million will be due upon the achievement of certain development, regulatory and commercial milestones. We will also pay ~~mid-single-digit~~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~~percentage (which decreases as product development progresses) of amounts received from such sublicensees. During the three and six months ended December 31, 2023 and 2022 we made no payments under the Presage license agreement.

~~Note 5.~~ BeiGene Collaboration

In October 2018, we entered into a clinical collaboration with BeiGene, Ltd. ~~(“BeiGene”)~~(BeiGene) to evaluate the safety and efficacy of zandelisib in combination with BeiGene’s zanubrutinib (marketed as Brukinsa®), an inhibitor of Bruton’s tyrosine kinase, for the treatment of patients with B-cell malignancies. Under the terms of the clinical collaboration agreement, we amended our ongoing Phase 1b trial to include evaluation of zandelisib in combination with zanubrutinib in patients with B-cell malignancies. Study costs are being shared equally by the parties, and we agreed to supply zandelisib and BeiGene agreed to supply zanubrutinib. We record the costs reimbursed by BeiGene as a reduction of our research and development expenses. We retained full commercial rights for zandelisib and BeiGene retained full commercial rights for zanubrutinib. With the discontinuation of the zandelisib program outside of Japan, this clinical collaboration ~~will be concluding with~~was terminated on September 28, 2023. During the ~~discontinuation~~three and six months ended December 31, 2023, we recorded approximately none and $0.1 million, respectively, in costs reimbursements, as a reduction of research and development costs in the ~~Phase 1b trial.~~condensed consolidated statements of operations. During the three and six months ended December 31, 2022, we recorded approximately $0.2 million and $0.3 million, respectively, in costs reimbursements, as a reduction of research and development costs in the condensed consolidated statements of operations.

~~Note 6. Net Loss Per Share~~

Basic and diluted net loss per share are computed using the weighted average number of shares of common stock outstanding during the period, less any shares subject to repurchase or forfeiture. There were no shares of common stock subject to repurchase or forfeiture for the three and nine months ended March 31, 2023 and 2022. Diluted net loss per share is computed based on the sum of the weighted average number of common shares and potentially dilutive common shares outstanding during the period.

~~Torreya Partners~~

In October 2022, we engaged Torreya Partners as a financial advisor to help explore additional strategic opportunities. As part of this engagement, we issued warrants to acquire shares of our common stock having a value equal to $~~0.5~~ ~~million. These warrants were issued during the three months ended March 31, 2023.

~~Note 8.~~9. Leases

In July 2020, we entered into a lease agreement (the ~~"Initial~~Initial Lease ~~Agreement")~~Agreement) for approximately 32,800 square feet of office space in San Diego, California. The ~~Initial~~ Lease Agreement was scheduled to expire in March 2028 but was extended by 20 months to November ~~30,~~ 2029, in accordance with the amended lease agreement ~~that~~ we entered into in January 2022 (the ~~"Amended~~Amended Lease ~~Agreement")~~Agreement). The Initial and Amended Lease Agreements are collectively referred to as the Lease Agreements. The Lease Agreements contain rent escalations over the lease term. In addition, the Lease Agreements contain an option to renew and extend the lease term, which is not included in the determination of the right-of-use (ROU) asset and operating lease liability, as it was not reasonably certain to be exercised. Upon commencement of the Amended Lease Agreement, to extend the lease term, we recognized an additional operating lease ROU asset and a corresponding operating lease liability. The Lease Agreements include variable non-lease components (e.g., common area maintenance, maintenance, etc.) that are not included in the ROU asset and operating lease liability and are reflected as an expense in the period incurred as a component of the lease cost.

The Amended Lease Agreement ~~which began on July 1, 2022 and expires on~~also provides for an additional ~~November 30, 2029~~12,300~~, provides additional~~ square feet of office space adjacent to our current office in San Diego. Upon taking control of the additional office space on July 1, 2022, we recognized operating lease ROU assets obtained in exchange for operating lease liabilities of $4.3 million. ~~The Initial Lease Agreement and Amended Lease Agreement are collectively referred to as the "Lease Agreements" and have been accounted for as operating leases.~~

Description of Capital Stock

Our total authorized share capital is 226,100,000 shares consisting of 226,000,000 shares of common stock, $0.00000002 par value per share, and 100,000 shares of preferred stock, $0.01 par value per share.

CommonStock

The holders of common stock are entitled to one vote per share. In the event of a liquidation, dissolution or winding up of our affairs, holders of the common stock will be entitled to share ratably in all our assets that are remaining after payment of our liabilities and the liquidation preference of any outstanding shares of preferred stock. All outstanding shares of common stock are fully paid and non-assessable. The rights, preferences and privileges of holders of common stock are subject to any series of preferred stock that we have issued or that we may issue in the future. The holders of common stock have no preemptive rights and are not subject to future calls or assessments by us.

PreferredStock

Our Board has the authority to issue up to 100,000 shares of preferred stock with a par value of $0.01 per share in one or more series and to fix the rights, preferences, privileges and restrictions in respect of that preferred stock, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption (including sinking fund provisions), redemption prices and liquidation preferences, and the number of shares constituting such series and the designation of any such series, without future vote or action by the stockholders. Therefore, the Board, without the approval of the stockholders, could authorize the issuance of preferred stock with voting, conversion and other rights that could affect the voting power, dividend and other rights of the holders of shares or that could have the effect of delaying, deferring or preventing a change of control. There were no shares of preferred stock outstanding as of December 31, 2023 and June 30, 2023.

Rights Agreement

On October 1, 2023, our Board approved and adopted a Rights Agreement (Rights Agreement) by and between us and Computershare, Inc., as Rights Agent (as defined in the Rights Agreement). Pursuant to the Rights Agreement, the Board declared a dividend of one preferred share purchase right (each a Right) for each outstanding share of our common stock, par value $0.00000002 (each a Common Share and collectively, the Common Shares). The Rights are distributable to stockholders of record as of the close of business on October 12, 2023. One Right also will be issued together with each Common Share issued by us after October 12, 2023, but before the Distribution Date, as defined in the Rights Agreement (or the earlier of the redemption or expiration of the Rights) and, in certain circumstances, after the Distribution Date.

~~Note 10.~~11. Share-based Compensation

We use ~~equity-based~~share-based compensation programs to provide long-term performance incentives for our employees. These incentives consist primarily of stock options and ~~RSUs.~~restricted stock units (RSU). In December 2008, we adopted the MEI Pharma, Inc. 2008 Stock Omnibus Equity Compensation Plan ~~(“Omnibus Plan”)~~(Omnibus Plan), as amended and restated from ~~time-to-time,~~time to time, under which ~~1,450,740~~1,850,739 shares of common stock are currently authorized for issuance. The Omnibus Plan provides for the grant of options and/or other stock-based or stock-denominated awards to our non-employee directors, officers, and employees. ~~In January 2023, our stockholders approved the increase of~~ ~~400,000~~ ~~additional shares available for future grant under the Omnibus Plan.~~ As of ~~March~~December 31, 2023, there were ~~583,468~~439,101 shares available for future grant under the Omnibus Plan.

In May 2021, we adopted the 2021 Inducement Plan ~~("Inducement Plan")~~(Inducement Plan), under which ~~125,000~~217,000 shares of common stock are authorized for issuance. The Inducement Plan is intended to assist us in attracting and retaining selected individuals to serve as employees who are expected to contribute to our success, by providing an inducement for such individuals to enter into employment with us, and to achieve long-term objectives that will benefit our stockholders. As of ~~March~~December 31, 2023, there were ~~25,185~~116,734 shares available for future grant under the Inducement Plan.

This Quarterly Report on Form 10-Q ~~("Quarterly Report")~~(Quarterly Report) includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the ~~“Securities Act”)~~Securities Act) and Section 21E of the Securities Exchange Act of 1934, as amended (the ~~“Exchange Act”)~~Exchange Act). All statements other than statements of historical facts contained in this Quarterly Report, including statements regarding the future financial position, business strategy and plans and objectives of management for future operations, are forward-looking statements. The words ~~“believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “should,” “plan,” “expect,”~~believe, may, will, estimate, continue, anticipate, intend, should, plan, expect, and similar expressions, as they relate to us, are intended to identify forward-looking statements. We have based these forward-looking statements largely on current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including, without limitation, those described in ~~“Risk Factors”~~Risk Factors in our ~~2022~~2023 Annual Report on Form 10-K ~~("2022~~(2023 Annual ~~Report")~~Report), as filed with the Securities and Exchange Commission on September ~~8, 2022.~~26, 2023. Set forth below is a summary of the principal risks we face:

~~Risks Related~~Summary Risk Factors

Our business is subject to numerous risks and uncertainties that you should consider before investing in our common stock. Set forth below is a summary of the ~~Company:~~principal risks we face:

•

We ~~have identified a material weakness~~are subject to risks relating to general economic conditions, including financial market volatility and disruption, elevated levels of inflation, and uncertain economic conditions in ~~our internal control over financial reporting~~the United States and determined that our disclosure controls and procedures were ineffective as of June 30, 2021, as a result of the restatement of our financial statements as of and for the years ended June 30, 2021 and 2020. Relevant unaudited interim financial information for each of the quarterly periods ended September 30, 2020 through December 31, 2021 have also been restated. In the future, we may identify additional material weaknesses or otherwise fail to maintain an effective system of internal control over financial reporting or adequate disclosure controls and procedures, which may result in material errors of our financial statements or cause us to fail to meet our periodic reporting obligations;abroad;

•

We will need substantial additional funds to progress the clinical trial programs for our drug candidates, to commercialize our drug candidates and to develop new compounds. The actual amount of funds we will need will be determined by a number of factors, some of which are beyond our control;

•

We may be required to seek additional capital through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties at terms which maybe unfavorable to us;

•

We are a ~~clinical stage clinical research and development stage~~clinical-stage pharmaceutical company focused on developing potential new therapies for cancer and are likely to incur operating losses for the foreseeable future;

•

The results of pre-clinical studies and completed clinical trials are not necessarily predictive of future results, and our current drug candidates may not have favorable results in later studies or trials;

•

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

•

Changes in drug candidate manufacturing or formulation may result in additional costs or delay;

•

If third parties with whom we collaborate on the development and commercialization of our drug candidates do not satisfy their obligations, do not otherwise pursue development or commercialization of our drug candidates or if they terminate their agreements with us, we may not be able to develop or commercialize our drug candidates;

•

We are subject to significant obligations to Presage in connection with our license of voruciclib, and we may become subject to significant obligations in connection with future licenses we obtain, which could adversely affect the overall profitability of any products we may seek to commercialize, and such licenses of drug candidates, the development and commercialization for which we are solely responsible, may never become profitable;

•

Our business strategy may include entry into additional collaborative or license agreements. We may not be able to enter into collaborative or license agreements or may not be able to negotiate commercially acceptable terms for these agreements;

•

Final approval by regulatory authorities of our drug candidates for commercial use may be delayed, limited or prevented, for reasons which may or may not be directly related to our drug candidates, and any of which would adversely affect our ability to generate operating revenues;

•

The FDA may determine that our drug candidates have undesirable risk-benefit profiles with respect to its evaluations of efficacy and/or side effects that could delay or prevent ~~their~~ regulatory approval or commercialization;

•

If we experience delays or difficulties in the enrollment of patients in clinical trials, our completion of clinical trials and receipt of necessary regulatory approvals could be delayed or prevented;

•

Changes in funding for the FDA and other government agencies or future government shutdowns could cause delays in the submission and regulatory review of marketing applications, which could negatively impact our business or prospects;

Table of Contents

•

Failure to obtain regulatory approval in foreign jurisdictions would prevent us from marketing our products internationally;

•

Any designation granted by the FDA for any of our product candidates may not lead to a faster development or regulatory review or approval process, and does not increase the likelihood that our product candidates will receive marketing approval. We may also not be able to obtain or maintain any such designation;

•

Any orphan drug designations we receive may not confer marketing exclusivity or other benefits;

~~Table of Contents~~

•

Even if we or our licensees receive regulatory approval to commercialize our drug candidates, our ability to generate revenues from any resulting products will be subject to a variety of risks, many of which are out of our control;

•

If any products we develop become subject to unfavorable pricing regulations, ~~third-party~~third party reimbursement practices or healthcare reform initiatives, our ability to successfully commercialize our products will be impaired;

•

Our drug candidates are subject to ongoing government regulation both before and after regulatory approval;

•

We may not be able to establish the contractual arrangements necessary to develop, market and distribute our drug candidates;

•

Our commercial opportunity will be reduced or eliminated if competitors develop and market products that are more effective, have fewer side effects or are less expensive than our drug candidates;

•

Our product candidates may face competition sooner than anticipated;

•

We rely on third parties to conduct our clinical trials and pre-clinical studies. If those parties do not successfully carry out their contractual duties or meet expected deadlines, our drug candidates may not advance in a timely manner or at all;

•

We will depend on third party suppliers and contract manufacturers for the manufacturing of our drug candidates and have no direct control over the cost and timing of manufacturing our drug candidates. Increases in the cost of manufacturing our drug candidates or delays in manufacturing would increase our costs of conducting clinical trials and could adversely affect our future profitability;

•

We rely on acquisitions or licenses from third parties to expand our pipeline of drug candidates;

•

Our commercial success is dependent, in part, on obtaining and maintaining patent protection and preserving trade secrets, which cannot be guaranteed;

•

Claims by other companies that we infringe on their proprietary technology may result in liability for damages or stop our development and commercialization efforts;

•

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property;

•

We may be subject to substantial costs stemming from our defense against ~~third-party~~third party intellectual property infringement claims;

•

We face a risk of product liability claims and claims may exceed our insurance limits;

•

Our employees, independent contractors, consultants, commercial partners, principal investigators, or ~~CROs~~clinical contract research organizations (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;

•

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

•

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

•

Negative U.S. and global economic conditions may pose challenges to our business strategy, which relies on funding from the financial markets or collaborators, including financial and other impacts of macroeconomic and geopolitical trends and events, including the conflicts in Ukraine and between Israel and Hamas and related regional and global ramifications;

•

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

•

Security breaches, cyber attacks and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer;

Table of Contents

•

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 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;

•

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

•

Our business could be negatively impacted as a result of actions by activist investors;

•

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;

•

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;

•

Because we do not intend to pay, and 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;

•

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

•

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

•

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

•

Our ~~fourth~~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; and

~~Table of Contents~~

•

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

~~Risks Related to the Proposed Merger:~~

•

The Exchange Ratio will not be adjusted based on the market price of our common stock or Infinity Common Stock, so the merger consideration at the Closing may have a greater or lesser value than at the time the Merger Agreement was signed;

•

~~If the conditions to the Merger are not satisfied or waived, the Merger may not occur;~~

•

~~The Merger may be completed even though a material adverse effect may result from the announcement of the Merger, industry wide changes or other causes;~~

•

If we and Infinity complete the Merger, the combined company may need to raise additional capital by issuing equity securities or additional debt or through licensing arrangements, which may cause significant dilution to the combined company’s stockholders or restrict the combined company’s operations;

•

Our directors and executive officers and Infinity's directors and executive officers have interests in the Merger that are different from yours and that may influence them to support or approve the Merger without regard to your interests;

•

Our securityholders and Infinity securityholders will have a reduced ownership and voting interest in, and will exercise less influence over the management of, the combined company following the completion of the Merger as compared to their current ownership and voting interests in the respective companies;

•

~~If the Merger is not completed, our stock price may fluctuate significantly;~~

•

During the pendency of the Merger, we may not be able to enter into a business combination with another party on more favorable terms because of restrictions in the Merger Agreement, which could adversely affect our respective business prospects;

•

~~Certain provisions of the Merger Agreement may discourage third parties from submitting competing proposals, including proposals that may be superior to the Merger;~~

•

~~The financial analyses, estimates and forecasts considered by us and Infinity in connection with the Merger may not be realized;~~

•

~~The announcement and pendency of the Merger, whether or not consummated, may adversely affect the trading price of our common stock and our business prospects;~~

•

Failure to consummate the Merger may result in either our or Infinity paying a termination fee to the other party and could harm the common stock price of the party obligated to pay the termination fee and such party’s future business and operations;

•

~~If the Merger is not consummated, we and Infinity would need to determine whether to continue its business, consummate another strategic transaction, or dissolve and liquidate its assets;~~

•

~~We or Infinity may waive one or more of the conditions to the Merger, and may do so without re-soliciting stockholder approval;~~

•

The Merger may not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, resulting in recognition of taxable gain or loss by Infinity stockholders in respect of their Infinity Common Stock;

•

~~Lawsuits could delay or prevent the Merger;~~

These risks are not exhaustive. Other sections of this report and our other filings with the Securities and Exchange Commission ~~("SEC")~~(SEC) include additional factors which could adversely impact our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for us to predict all risk factors, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. We cannot assure you that the events and circumstances reflected in the forward-looking statements will be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Past performance may not be an indicator of future results. The following discussion is qualified in its entirety by, and should be read in conjunction with, the more detailed information set forth in the condensed consolidated financial statements and the notes thereto appearing elsewhere in this Quarterly Report and the audited financial statements and notes thereto included in our ~~2022~~2023 Annual Report, as filed with the SEC. Operating results are not necessarily indicative of results that may occur in future periods.

Overview

MEI Pharma, Inc. (Nasdaq: MEIP) is a ~~clinical stage~~clinical-stage pharmaceutical company ~~focused on~~committed to developing ~~potential new therapies for cancer. MEI Pharma’s portfolio of~~novel and differentiated cancer therapies. We build our pipeline by acquiring promising cancer agents and creating value in programs through clinical development, strategic partnerships, and out-licensing or commercialization, as appropriate. Our approach to oncology drug development is to evaluate our drug candidates ~~includes clinical-stage candidates~~in combinations with ~~differentiated or novel~~standard-of-care therapies to overcome known resistance mechanisms of

~~Table of Contents~~

~~action intended to~~and address ~~unmet~~clear medical needs to provide improved patient benefit. The drug candidate pipeline includes voruciclib, an oral cyclin-dependent kinase 9 (CDK9) inhibitor, and ~~deliver improved benefit to patients, either as standalone treatments or in combination with other therapeutic options.~~ME-344, an intravenous small molecule inhibitor of mitochondrial oxidative phosphorylation (OXPHOS). Our common stock is listed on the Nasdaq Capital Market under the symbol ~~“MEIP.”~~MEIP.

~~In February 2023, we, Infinity Pharmaceuticals, Inc. (“Infinity”), and Meadow Merger Sub, Inc.,~~We believe our wholly owned subsidiary (“Merger Sub”) entered into an agreement and plan of merger (“Merger Agreement”). The Merger Agreement provides that Merger Sub will merge with and into Infinity, with Infinity being the surviving entity as a wholly-owned subsidiary of us. ~~Upon completion of the Merger, our stockholders will own approximately 58% of the combined company’s outstanding common stock and Infinity's stockholders will own approximately 42%.~~ ~~Subject to stockholder approval and the subsequent closing of the merger, the combined company~~cash is expected to be renamed and trade on the Nasdaq Stock Market. The combined company would be headquartered in San Diego, California. The Merger Agreement has been approved by the Boards of Directors of both companies. The merger is expected to close in mid-2023, subject to approvals by our and Infinity's stockholders, respectively.

In accordance with the Merger Agreement, prior to the consummation of the Merger, Daniel P. Gold, will resign as Chief Executive Officer. Dr. Gold will continue to serve on the Board of Directors of the combined company. David M. Urso, current Chief Operating Officer and General Counsel, will become Chief Executive Officer.

In December 2022, we announced plans to realign our clinical development efforts after jointly deciding with our development partner, Kyowa Kirin Co., Ltd. (“Kyowa Kirin”), to discontinue development of our lead drug candidate, zandelisib, outside of Japan. In connection with the realignment, we are focusing our development efforts on our two earlier stage clinical assets, voruciclib and ME-334. Additionally, we initiated a staggered workforce reduction, affecting 28 employees in December 2022 (representing approximately 27% of our workforce) and an additional 14 employees as of April 2023. Following completion of the close of the zandelisib development program, workforce reductions completed to date and any further workforce reductions necessary to fully align resources going forward, we expect that our existing cash, cash equivalents and short-term investments will be sufficient to fund operations for at least 12 months and through the reporting of clinical data readouts from the ~~issuance~~ongoing voruciclib Phase 1 and ME-344 Phase 1b clinical programs.

Table of ~~this Quarterly Report.~~Contents

On October 31, 2023, we announced entry into a Cooperation Agreement (Cooperation Agreement) with Anson Funds (Anson) and Cable Car Capital (Cable Car) which contains the following key terms:

•

Capital Return to Stockholders: Payment of a dividend to stockholders in the amount of $1.75 per share of common stock to all stockholders, which was issued on December 6, 2023. Additionally, a second return of capital of not to exceed $9.33 million (the Potential Second Return of Capital) could be issued if authorized by the board of directors (Board) should our ongoing ME-344 phase 1b trial fail to meet certain endpoints or our Board determines not to proceed with a second cohort. The Potential Second Return of Capital may take the form of a dividend or tender offer and is subject to Board approval as well as modification associated with applicable requirements under Delaware law, as detailed in the Cooperation Agreement.

•

Director Resignations: Three of our former directors resigned from the Board concurrently with the execution of the Cooperation Agreement and did not seek reelection at the 2024 Annual Meeting of Stockholders (2024 Annual Meeting).

•

Stockholder Designees Added to the Board: The appointment of two directors designated by Anson and Cable Car, with an additional director appointment mutually agreed upon by us and Anson and Cable Car. These appointments were effective immediately and the new directors were nominated for election by us and elected at the fiscal 2024 Annual Meeting to serve for a three-year term.

•

Formation of a Capital Allocation Committee: The formation of a Capital Allocation Committee, comprising five directors including the three new directors. The Capital Allocation Committee will advise the Board on the strategic allocation of capital to support (i) the development of our drug candidate programs and (ii) other value creation or preservation measures, with a view toward maximizing stockholder value.

As part of the Cooperation Agreement, Anson and Cable Car withdrew their consent solicitation and agreed to abide by customary standstill provisions. Additionally, we reimbursed Anson and Cable Car’s fees and expenses related to their engagement with us as of the date of the Cooperation Agreement, in the amount of $1.1 million.

Clinical Development Programs

Our business strategy is to build our pipeline by licensing or acquiring promising cancer agents and creating value in programs through development, strategic partnerships and commercialization, 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. Ourclinical-stage drug candidate pipeline includes voruciclib, an oral ~~cyclin-dependent kinase 9 (“CDK9”)~~CDK9 inhibitor, and ME-344, an intravenous small molecule mitochondrial inhibitor targeting ~~the oxidative phosphorylation pathway~~OXHPHOS in the mitochondria.

~~Study pending initiation.~~

Voruciclib: Potent Orally Administered CDK9 Inhibitor in Phase 1 Studies

Voruciclib is a potent and selective orally administered CDK9 inhibitor. Voruciclib is being ~~evaluated~~studied in a Phase 1b1 trial evaluating dose and schedule in patients with acute myeloid leukemia ~~(“AML”)~~(AML) and B-cell ~~malignancies.~~malignancies as a single-agent, and in combination with the B-cell lymphoma 2 (BCL2) inhibitor venetoclax (marketed as Venclexta®) in patients with AML.

Voruciclib Scientific Overview: Cell Cycle Signaling

CDK9 has important functions in cell cycle regulation, including the modulation of two therapeutic targets in cancer:

•

CDK9 is a transcriptional regulator of the myeloid leukemia cell differentiation protein ~~(“MCL1”)~~(MCL1), a member of the family of anti-apoptotic proteins which, when elevated, may prevent the cell from undergoing cell ~~death.~~death and result in poor prognosis in cancer. Inhibition of CDK9 blocks the production of MCL1, which is also an established resistance mechanism to the ~~B-cell lymphoma (“BCL2”)~~BCL2 inhibitor ~~venetoclax (marketed as Venclexta®).~~venetoclax.

~~Targeting~~Directly inhibiting MCL1 and MYC ~~directly~~ has historically been difficult, but CDK9 is a promising approach to indirectly target ~~this oncogene.~~these oncogenes.

Voruciclib: Inhibition of MCL1

CDK9 is a known transcriptional regulator of MCL1. Over expression of MCL1 is frequently observed in many tumor types and is closely associated with tumorigenesis, poor prognosis and drug resistance. In AML, MCL1 is upregulated in about half of patients withrelapsed and refractory (R/R) disease and is associated with poor prognosis in these patients. Also important, high levels of MCL1 expression are associated with resistance to venetoclax.

In pre-clinical studies, voruciclib shows dose-dependent suppression of MCL1; in December 2017, a study of voruciclib published in the journal Nature Scientific Reports reported that the combination of voruciclib plus the BCL-2 inhibitor venetoclax was capable of inhibiting two master regulators of cell survival, MCL-1 and BCL-2, and achieved synergistic antitumor effect in an aggressive subset of DLBCL ~~pre-clinical models.~~cells.

In a peer reviewed manuscript published in 2020, ~~by Luedtke et al,~~ it was reported that the inhibition of CDK9 by voruciclib synergistically enhances cell death induced by the ~~Bcl-2 selective~~BCL-2 inhibitor venetoclax in preclinical models of AML. The data demonstrated that voruciclib synergizes with venetoclax to induce programmed cell death, or apoptosis, in both AML cell lines and primary patient samples. It was also demonstrated that voruciclib downregulates MCL1, which is relevant for the synergy between voruciclib and venetoclax, and further that voruciclib ~~also~~ downregulates MYC, which also contributes to the synergies with venetoclax.

The research ~~presented~~ suggests that voruciclib is potentially an attractive therapeutic ~~target~~agent for treating cancers in combination with venetoclax or other BCL-2 inhibitors, to address potential resistance associated with MCL1, and is supportive of our ongoing clinical evaluation of voruciclib in B-cell malignancies and AML.

Voruciclib: Inhibition of MYC

Many cancers are associated with ~~overexpression~~over expression of MYC, a transcription factor regulating cell proliferation and growth. CDK9 is a known regulator of MYC transcription and a modulator of MYC protein phosphorylation. Data reported at the American Association for Cancer Research ~~(“AACR”)~~(AACR) Annual Meeting 2021 in preclinical models ~~demonstrates~~demonstrated that voruciclib:

•

Results in a rapid decrease in the phosphorylation of proteins that promote MYC transcription;

•

Rapidly decreases phosphorylation of MYC protein on Ser62, a site implicated in stabilizing MYC in KRAS mutant cancers;

•

Possesses single agent activity against multiple KRAS mutant cancer cell lines both in vitro and in vivo; and

•

Synergistically inhibits KRAS G12C mutant cancer cell lines in combination with KRAS G12C inhibitors, both in vitro and in vivo.

The research presented suggests that voruciclib could be an attractive therapeutic agent for both hematological cancers, ~~including~~as well as solid tumors, dependent on the activity of MYC.

Clinical ~~Program~~Programs

We are evaluating patients with hematological malignancies in a Phase 1b1 clinical trial evaluating the dose and schedule of ~~voruciclib.~~voruciclib monotherapy and in combination with venetoclax. The trial started with the evaluation of dose and schedule of voruciclib as a monotherapy in patients with relapsed and refractory B-cell malignancies and AML after failure of prior standard therapies to determine the safety, preliminary efficacy and maximum tolerated dose. WeAfter completing the monotherapy dose escalation stage of the study, we are now ~~also~~ evaluating the dose and schedule of voruciclib in combination with venetoclax, a ~~BCL2~~BCL-2 inhibitor, initially in patients with ~~AML and subsequently across multiple indications where BCL2 inhibition has been shown to be effective.~~R/R AML. The primary goal of the Phase 1b1 study is to assess the safety, and possible synergies, of voruciclib administered in combination with venetoclax. ~~We are planning~~Clinical data is expected to ~~report key interim~~be reported from the dose escalation portion of the ongoing Phase 1 clinical ~~data from this~~ trial ~~around~~evaluating voruciclib plus venetoclax in patients with R/R AML in the first calendar ~~year-end 2023.~~quarter of 2024.

As we reported in a poster presented at the American Society of Hematology ~~2021 annual meeting~~(ASH) Annual Meeting in December 2023, the voruciclib monotherapy dose escalation/expansion stage of the study enrolled a total of 40 patients and is complete. The majority of patients (n=21) had AML and the remaining patients (n=19) had B-cell malignancies. Of the 40 patients enrolled, the first 16 were dosed daily continuously at 50 and 100 mg and the following 24 patients were dosed on an intermittent schedule (14 consecutive days on therapy in a ~~poster presentation, data~~28-day cycle) at 100, 150 and 200 mg. All patients were heavily pre-treated with a median of three prior therapies

(range 1-9), and five patients had prior hematopoietic stem cell transplant. Voruciclib at doses up to ~~date from the Phase 1 study evaluating voruciclib as a monotherapy~~200 mg administered on ~~an optimized schedule of~~ 14 consecutive days in a 28-day cycle (Cohort 2) was well ~~tolerated. No~~tolerated with no dose limiting toxicities (DLT) reported. The most common adverse events (≥20% of patients) were diarrhea, nausea, anemia and fatigue. The large majority of adverse events were Grade 1-2; of note, the only Grade 3-4 adverse events in Cohort 2 were diarrhea (n=1) and anemia (n=5). Pharmacokinetics were dose proportional and a mean half-life of approximately 24 hours supports once daily dosing.

On the intermittent dosing schedule selected for further development, no DLTs were observed, there were no Grade 3 or higher drug related toxicities, and ~~no significant myelosuppression~~dose escalation was ~~seen~~stopped at 200 mg before reaching the maximum tolerated dose because plasma concentrations reached levels considered sufficient for target inhibition. In the 21 patients enrolled with AML, one patient at 100 mg achieved a morphologic leukemia-free state and nine patients had disease stabilization, which lasted at least three months in two patients. In the 19 patients enrolled with B-cell malignancies, four patients had stable disease with a decrease in tumor size. Initial results from correlative studies assessing myeloid leukemia cell differentiation protein (Mcl-1) and RNA Pol II phosphorylation on Ser2 (RNA Pol II p-S2) demonstrated reduction in expression consistent with the anticipated on-target pharmacodynamic effect of voruciclib on Mcl-1 and RNA Pol II p-S2.

As further presented in the ASH 2023 poster, the second stage of the study evaluating the combination of voruciclib and venetoclax in patients with ~~B-cell malignancies, suggesting~~R/R AML is ongoing. All patients were heavily pre-treated with a ~~lower likelihood~~median of ~~additive toxicities~~three prior therapies including venetoclax.

Disease stabilization was~~venetoclax in patients with relapsed or refractory AML. No DLTs have been reported and no evidence of overlapping toxicity has been observed to date. Voruciclib doses from 50 mg to 200 mg administered in ~~heavily pretreated~~combination with venetoclax, as reported in the ASH 2023 poster, demonstrated anti-tumor activity as evidenced by objective responses and reductions in transfusions, with multiple patients ~~and differentiation syndrome was observed in AML patients, which is indicative of biologic activity.~~continuing on therapy for ≥ four months.

Voruciclib was also previously evaluated in more than 70 patients with solid tumors in multiple Phase 1 studies. The totality of the clinical data, along with data from pre-clinical studies, suggests voruciclib’s ability to inhibit its molecular target at a projected dose as low as 150 mg daily. In one clinical study, voruciclib was evaluated in combination with vemurafenib (marketed as Zelboraf®) in nine patients with BRAF mutated advanced/inoperable malignant melanoma. All three BRAF/MEK naive patients achieved a response: two partial responses and one complete response. In this study voruciclib was dosed at 150 mg daily plus vemurafenib 720 mg or 960 mg twice daily in 28-day cycles. The most common adverse events were fatigue, constipation, diarrhea, arthralgia and headache. One instance of grade 3 fatigue was dose limiting and no serious adverse events related to voruciclib were reported. Other clinical studies evaluated voruciclib at doses up to 850 mg in patients with solid tumors, demonstrating additional evidence of potential biologic activity and an adverse event profile generally consistent with other drugs in its class.

ME-344: ~~Clinical Stage~~Clinical-stage Mitochondrial Inhibitor with Combinatorial Potential

ME-344 is ~~our~~a novel ~~isoflavone-derived mitochondrial inhibitor~~ drug candidate that ~~demonstrates tumor selective activity in pre-clinical studies. It targets the oxidative phosphorylation~~inhibits mitochondrial OXPHOS, a fundamental metabolic pathway involved in the production of adenosine triphosphate ~~(“ATP”) production~~(ATP) in the mitochondria. ATP provides energy to drive many metabolic cell processes, including division, proliferation, and growth. By disrupting the production of ATP, ME-344 has been ~~evaluated~~shown to induce cancer cell death in nonclinical models and was associated with antitumor activity in clinical ~~studies, including~~studies.

Currently, we are evaluating ME-344 in combination with bevacizumab (AVASTIN®) in patients with metastatic colorectal cancer.

ME-344 Scientific Overview: Cancer Metabolism

Energy supplied in the form of ATP fuels tumor metabolism supporting cell division and growth. Accordingly, tumor cells often display a high metabolic rate to support tumor cell survival and proliferation. This heightened metabolism requires a continual supply of energy in the form of ATP. Anti-angiogenics, such as the vascular endothelial growth factor (VEGF) inhibitor bevacizumab, have the potential to normalize vasculature and decrease reliance on glycolysis for ATP. The resulting reduction in glycolysis may trigger an increased dependence on mitochondrial ATP production for energy to support continued tumor proliferation. In such cases of tumor plasticity, the combination of ME-344 and bevacizumab may induce metabolic synthetic lethality, providing a novel therapeutic strategy. Specifically, leveraging the ability of antiangiogenics like bevacizumab to reduce glycolysis and force tumor cells to switch to mitochondrial respiration via OXPHOS, which is inhibited by ME-344, may reduce access to ATP needed for cell division and growth in tumors.

We obtained initial clinical validation of this approach in a completed investigator-initiated, multi-center, randomized, controlled, window of opportunity clinical trial evaluating ME-344 in combination with ~~the vascular endothelial growth factor (“VEGF”) inhibitor~~ bevacizumab ~~(marketed as Avastin ®)~~ that enrolled a total of 42 patients with human epidermal growth factor receptor 2 ~~(“HER2”)~~(HER2) negative breast cancer.An earlier Phase 1 clinical study evaluating ME-344 as a single-agent in patients with refractory solid tumors also demonstrated anti-tumor activity, further validating the potential of mitochondrial inhibition as a promising therapeutic modality.

We are currently evaluating the combination of ME-344 ~~Scientific Overview: Cancer Metabolism~~

~~Tumor cells often display a high metabolic rate to support cell division~~ and ~~growth. This heightened metabolism requires a continual supply of energy~~bevacizumab in the form of ATP. The two major sources of ATP are the specialized cellular organelles termed mitochondria and through the metabolism of carbohydrates via the glycolysis pathway, which is frequently unregulatedpatients with metastatic colorectal cancer in ~~cancer cells in a phenomenon called the Warburg Effect.~~

ME-344 was identified through a screen of more than 400 new chemical structures originally created based on the central design of naturally occurring plant isoflavones. We believe that some of these synthetic compounds, including our drug candidate ME-344, interact with specific mitochondrial enzyme targets, resulting in the inhibition of ATP generation. When these compounds interact with their target, a rapid reduction in ATP occurs, which leads to a cascade of biochemical events within the cell and ultimately to cell death.an ongoing Phase 1b study.

Clinical Program

ME-344 has been evaluated pre-clinically and clinically as a single agent and in combination with anti-angiogenics such as bevacizumab. When evaluated as a single agent, ME-344 demonstrated evidence of ~~single agent~~ activity against refractory solid tumors in a Phase 11b trial, and in pre-clinical studies tumor cells treated with ME-344 resulted in a rapid loss of ATP and cancer cell death. In addition to single agent activity, ME-344 ~~may~~has also ~~have~~demonstrated significant potential in combination with anti-angiogenic therapeutics. ~~In pre-clinical~~

Pre-clinical studies, ~~it was~~have shown that one outcome of anti-angiogenics ~~was to reduce the~~is a reduced rate of glycolysis in tumors as a mechanism to slow tumor growth. However, when faced with reduced glycolysis and reduced ATP production, tumor metabolism was able to shift to mitochondrial metabolism for energy production to support continued tumor proliferation. In such cases of tumor plasticity in the presence of treatment with anti-angiogenics, contemporaneously targeting the mitochondria as an alternative metabolic source of ATP with ME-344 may open an important therapeutic opportunity.

Support for this combinatorial use of ME-344 was first published in the June 2016 edition of Cell Reports; pre-clinical data from a collaboration with the Spanish National Cancer Research Centre in Madrid demonstrated mitochondria-specific effects of ME-344 in cancer cells, including substantially enhanced anti-tumor activity when combined with agents that inhibit the activity of VEGF. These data demonstrating the potential anti-cancer effects of combining ME-344 with a VEGF inhibitor due to an inhibition of both mitochondrial and glycolytic metabolism provided a basis for commencement of an investigator-initiated trial of ME-344 in combination with bevacizumab in HER2 negative breast cancer patients.

Results published in the November 2019 issue of Clinical Cancer Research from a ~~multicenter,~~multi-center, investigator-initiated, randomized, ~~open-label,~~controlled, clinical trial that evaluated the combination of ME-344 and bevacizumab in 42 women with early HER2-negative breast cancer further support the combinatorial use of ME-344 with anti-angiogenic therapeutics.

The primary objective of the trial was to show proof of ME-344 biologic activity as measured by ~~Ki67~~ reductions in ~~the presence of~~ the nuclear protein Ki67 (expression of which is strongly associated with tumor cell proliferation and growth) from days 0 to 28 compared to the control group who received bevacizumab alone. Secondary objectives included determining whether ME-344 biologic activity correlates with vascular normalization. The data ~~demonstrate~~demonstrated significant biologic activity in the ME-344 treatment group:

•

In ME-344 treated patients, mean absolute Ki67 decreases were 13.3 compared to an increase of 1.1 in the bevacizumab monotherapy group (P=0.01).

Table of Contents

•

In ME-344 treated patients, mean relative Ki67 decreases were 23% compared to an increase of 186% in the bevacizumab monotherapy group (P < 0.01).

•

The mean relative Ki67 reduction in patients experiencing vascular normalization in the ME-344 treated patients was 33%, compared to an increase of 11.8% in normalized patients from the bevacizumab monotherapy group (P=0.09). Approximately one-third of patients in each arm had vascular normalization.

Treatment was generally well tolerated; three grade 3 adverse events of high blood pressure were reported, two in the ME-344 arm and one in the bevacizumab monotherapy arm.

Results from our earlier, first-in-human, single-agent Phase 1 clinical trial of ME-344 in patients with refractory solid tumors were published in the April 1, 2015 edition of Cancer. The results indicated that eight of 21 evaluable patients (38%) treated with ME-344 achieved stable disease or better, including five who experienced progression-free survival that was at least twice the duration of their last prior treatment before entry into the trial. In addition, one of these patients, a heavily pre-treated patient with small cell lung

cancer, achieved a confirmed partial response and remained on study for two years. ME-344 was generally well tolerated at doses equal to or less than 10 mg/kg delivered on a weekly schedule for extended durations. Treatment-related adverse events included nausea, dizziness and fatigue. Dose-limiting toxicities were observed at both the 15 mg/kg and 20 mg/kg dose levels, consisting primarily of grade 3 peripheral neuropathy.

Additionally, ME-344 may also have clinical potential against hematological malignancies. At the AACR Annual Meeting 2022, a poster presentation reported results from preclinical studies exploring the ability of ME-344 to enhance the activity of venetoclax against AML. Data from the in vitro and in vivo preclinical studies evaluating the combination of ME-344 with venetoclax in standard-of-care-resistant AML cell lines and relapsed or refractory AML patient samples suggest that ME-344, both alone and in combination with venetoclax, inhibits purine biosynthesis, suppresses oxidative phosphorylation, induces apoptosis and decreases MCL-1, which together target metabolic vulnerabilities of AML cells. The data demonstrated that ME-344 and venetoclax prolong survival in MV4-11 and MV4-11/AraC-R-derived xenograft AML models. The poster ~~concludes~~concluded that ME-344 enhances venetoclax activity against AML cells including resistant AML.

Zandelisib: PI3Kδ Inhibitor Overview

Zandelisib is an oral, once-daily, selective PI3Kδ inhibitor that we were jointly developing with ~~Kyowa Kirin~~KKC under a global license, development and commercialization agreement entered into in April 2020.

In March 2022, we and ~~Kyowa Kirin~~KKC reported the outcome of an end of Phase 2 meeting with the FDA wherein the agency discouraged a filing based on data from a single-arm Phase 2 ~~trial, called~~ TIDAL ~~evaluating zandelisib in patients with relapsed or refractory follicular lymphoma.~~trial. At this meeting, the FDA stated that data generated from single arm

studies such as the Phase 2 TIDAL trial are insufficient to adequately assess the risk/benefit of ~~PI3K~~PI3Kδ inhibitors evaluating indolent non-Hodgkin lymphoma. At that time, the FDA emphasized that the ~~companies~~company continue efforts with the ongoing randomized Phase 3 COASTAL trial evaluating patients with relapsed or refractory follicular or marginal zone lymphomas. Subsequently, at an April 2022 meeting of the FDA Oncology Drugs Advisory Committee, the committee voted that future approvals of ~~PI3K~~PI3Kδ inhibitors for hematologic malignancies should be supported by randomized data.

In November 2022, we and ~~Kyowa Kirin~~KKC met with the FDA in a follow-up meeting to the March 2022 end of Phase 2 meeting. At this meeting, the FDA provided further guidance regarding the design and statistical analysis for the Phase 3 COASTAL trial. Following the November meeting, the companies jointly concluded that a clinical trial consistent with the recent FDA guidance, including modification of the ongoing COASTAL trial, would likely not be feasible to complete within a time period that would support further investment or with sufficient certainty of the regulatory requirements for approval to justify continued global development efforts. As a result, we and ~~Kyowa Kirin~~KKC jointly decided to discontinue global development of zandelisib for indolent forms of non-Hodgkin lymphoma outside of Japan. The discontinuation of zandelisib development outside of Japan was a business decision based on the most recent regulatory guidance from the FDA and is not related to the zandelisib clinical data generated to date.

~~Kyowa Kirin has been evaluating whether~~ After making the joint decision to ~~continue developing zandelisib in~~terminate development outside of Japan, we and after meeting with the PMDA has concluded that conducting a randomized study consistent with agency guidance to support a marketing application would likely not be feasible to complete within a time period that would support further investment. As a result, in May 2023, Kyowa Kirin decided to discontinue development of zandelisib in Japan. The discontinuation of zandelisib in Japan was a business decision by Kyowa Kirin based on the most recent regulatory guidance from the PMDA and is not related to the zandelisib clinical data generated to date.

~~We and Kyowa Kirin have begun~~KKC began closing all ongoing zandelisib clinical studies outside of Japan, including the Phase 3 COASTAL trial, the Phase 2 TIDAL trial, and the Phase 2 CORAL trial.

Subsequently, in May 2023, KKC decided to discontinue development of zandelisib in Japan. The discontinuation of zandelisib in Japan was a business decision by KKC based on the most recent regulatory guidance from the Pharmaceuticals and Medical Devices Agency in Japan and was not related to the zandelisib clinical data generated to date.

~~Kyowa Kirin~~On July 14, 2023, we entered into a Termination Agreement (the Termination Agreement) with KKC to terminate all agreements between the parties and cease further zandelisib clinical development globally. As of December 31, 2023, activities associated with the compassionate use supply were completed. We anticipate completing the wind-down activities associated with the KKC Commercialization Agreement in fiscal year 2024.

KKC License, Development and Commercialization Agreement

In April 2020, we entered into the ~~Kyowa Kirin~~KKC Commercialization Agreement under which we granted to ~~Kyowa Kirin~~KKC a co-exclusive, sublicensable, payment-bearing license under certain patents and know-how controlled by us to develop and commercialize zandelisib and any pharmaceutical product containing zandelisib for all human indications in the U.S. (the ~~“U.S. License”)~~U.S. License), and an exclusive (subject to certain retained rights to perform obligations under the ~~Kyowa Kirin~~KKC Commercialization Agreement), sublicensable, ~~payment-bearing,~~payment- bearing, license under certain patents and know-how controlled by us to develop and commercialize zandelisib and any pharmaceutical product containing zandelisib for all human indications in countries outside of the U.S. (the ~~“Ex-U.S.”~~Ex-U.S. and the ~~“Ex-U.S. License”)~~Ex-U.S. License). ~~Kyowa Kirin~~Also under the KKC Commercialization Agreement, we were granted ~~to us~~ a co-exclusive, sublicensable, license under certain patents and know-how controlled by ~~Kyowa Kirin~~KKC to develop and commercialize zandelisib for all human indications in the U.S., and a co-exclusive,

Pursuant to the Termination Agreement:

•

we regained full, global rights to develop, manufacture and commercialize zandelisib, subject to KKC's limited rights to use zandelisib for compassionate use (as more specifically defined in the Termination Agreement) in certain expanded access programs for the existing patients who have been enrolled in Japanese clinical trial sponsored by KKC until November 30, 2027, and for which KKC is fully liable;

•

each party released the other party from any and all claims, demands, etc. arising from the KKC Commercialization Agreement, excluding certain surviving claims; and

•

we are obligated to deliver a discrete quantity of materials to facilitate KKC's compassionate use activities.

As of June 30, 2023, we had $64.9 million of aggregate deferred revenue associated with the KKC Commercialization Agreement, of which $64.5 million was allocated to the U.S. License and $0.3 million was allocated to the Development Services performance obligations which were recognized based on the proportional performance of these development activities through wind-down of the associated trials. As further discussed in Note 7. License Agreements, in connection with the execution of the Termination

Research and development expenses consist primarily of clinical trial costs ~~(including~~and includes payments to contract research organizations ~~“CROs”),~~CROs, 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 decreased $19.5 million primarily as a result of the discontinuation of the program during ~~the nine months ended March 31, 2023.~~fiscal year 2023 with lower costs in fiscal year 2024 associated with wind-down activities. Costs related to voruciclib decreased $1.0 million mainly due to lower ~~drug~~recognized clinical costs in the Phase 1 study. Costs related to ME-344 increased $1.8 million due to higher clinical and manufacturing ~~costs and clinical~~ costs related to the Phase 1b study. ~~Costs related to ME-344 decreased due to decreased drug manufacturing costs and clinical costs related to the Phase 1b study. The increase in other~~Other research and development costs isdecreased $8.7 million primarily due to a decrease of $7.4 million in personnel costs resulting from our reductions in workforce, including ~~severance costs related to the reduction~~a $0.7 million decrease in ~~force, offset by lower share-based compensation expenses.~~one-time employee termination benefits and a $0.8 million decrease in noncash stock-based compensation.

General and Administrative: General and administrative expenses decreased by ~~$1.6~~$1.4 million to ~~$23.2~~$14.5 million for the ~~nine~~six months ended ~~March~~December 31, 2023 compared to ~~$24.8~~$16.0 million for the ~~nine~~six months ended ~~March~~December 31, 2022. The decrease iswas primarily due to $2.3 million less personnel costs ~~related to the reduction~~resulting from our reductions in ~~force~~workforce, $0.4 million less noncash stock-based compensation, and $0.5 million less corporate overhead costs partially offset by ~~increased~~a $1.7 million increase in legal fees ~~and investment banking fees as a result of~~primarily associated with the ~~proposed merger agreement.~~Cooperation Agreement.

Other Income, net: Other income, ~~or expense:~~net, decreased by approximately $1.0 million to $2.0 million for the six months ended December 31, 2023 compared to $2.9 million for the six months ended December 31, 2022. We recorded a ~~non-cash~~noncash gain of $1.6 million during the ~~nine~~six months ended ~~March~~December 31, ~~2023~~2022, due to a change in the fair value of our warrant liability ~~compared to a non-cash~~with no similar gain ~~of $20.8 million~~ during the ~~nine~~six months ended ~~March~~December 31, ~~2022. The change~~2023, because of the underlying warrants expiring in ~~the warrant liability is primarily due to changes in our stock price.~~May 2023. Additionally, we received interest and dividend income of ~~$2.3~~$2.0 million for the ~~nine~~six months ended ~~March~~December 31, 2023 compared to ~~$78,000~~$1.3 million for the ~~nine~~six months ended ~~March~~December 31, 2022. The increase in interest and dividend income is primarily due to higher yields during the ~~nine~~six months ended ~~March~~December 31, 2023 compared to the ~~nine~~six months ended ~~March~~December 31, 2022.

Liquidity and Capital Resources

We have accumulated losses of ~~$396.0~~$360.7 million since inception and expect to incur operating losses and generate negative cash flows from operations for the foreseeable future. As of ~~March~~December 31, 2023, we had ~~$112.0~~$59.5 million in cash and 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 Quarterly 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 operations and operating expenses may affect actual future use of existing cash resources. 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 ~~nine~~six months ended ~~March~~December 31, 2023 ~~was $41.2~~of $29.5 million ~~as compared~~consisted of our net income of $45.3 million and $2.1 million for noncash items offset by $77.0 million in changes in our operating assets and liabilities primarily due to ~~net~~recognition of $64.9 million in noncash deferred revenue. Net cash used in operating activities ~~of $33.2 million~~ for the ~~nine~~six months ended ~~March 31, 2022. The increase in net cash used in operating activities period over period reflects the receipt of two $10.0 million milestones during the nine months ended March~~December 31, 2022 ~~related to the Kyowa Kirin Commercialization Agreement, with no corresponding receipt for the nine months ended March 31, 2023, as well as other~~of $29.1 million consisted of our net loss of $6.4 million and changes in ~~working capital.~~our operating assets and liabilities of $24.3 million partially offset by $1.7 million in noncash items.

~~Contractual Obligations~~Capital Resource Requirements

~~We have contracted with various consultants and third parties~~As previously discussed in the overview section above, we may be required to ~~assist us~~pay a second return of capital of not to exceed $9.33 million if authorized by our Board as further described 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.

We lease office space in San Diego, California under non-cancelable operating leases. The leases are subject to additional variable non-lease component charges (e.g., common area maintenance, maintenance, etc.). See Note 8 ~~Leases~~ ~~of the unaudited condensed consolidated financial statements for additional details related to our lease obligations.~~

As part of this engagement,~~20 months through November 2029. The amended lease agreement also provided for additional lease space that we will pay a transaction fee equal to 20% of aggregate consideration, up to a maximum of $2.0 million, upon completion of a strategic transaction. As of March 31, 2023, we have not accrued any amount for potential future transaction fees.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

Our exposure to market interest rates relates primarily to the investments of cash balances and short-term investments. We have cash reserves held in U.S. dollars and we place funds on deposit with financial institutions, which are readily available. Our short-term investments consist solely of U.S. government securities with a maturity of three to twelve months.

We place our cash deposits with high credit quality financial institutions and by policy limit the amount of credit exposure to any one corporation or bank. These deposits are in excess of the Federal Deposit Insurance Corporation ~~(“FDIC”)~~(FDIC) insurance limits. We are adverse to principal loss and we ensure the safety and preservation of our invested funds by limiting default risk, market risk and reinvestment risk. We seek to mitigate default risk by depositing funds with high credit quality financial institutions, by limiting the amount of credit exposure to any one corporation or bank, by purchasing short-term investments consisting of U.S. government securities, and by positioning our portfolio to respond appropriately to a significant reduction in a credit rating of any such financial institution.

~~Table of Contents~~

We do not consider the effects of interest rate movements to be a material risk to our financial condition.

Item 4. Controls and Procedures

(a) Disclosure Controls and Procedures

~~We maintain~~Our management, with the participation of our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of December 31, 2023. Based on such evaluation, our CEO and CFO have concluded that, ~~are designed~~as of December 31, 2023, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit ~~pursuant to~~under the ~~Securities and~~ Exchange Act ~~of 1934, as amended (the "Exchange Act"),~~ is recorded, processed, summarized and reported, within the time periods specified in the U.S. Securities and Exchange Commission, or SEC’s, rules and forms, ~~of the SEC,~~ and ~~that such information~~ is accumulated and communicated to our management, including our ~~Chief Executive Officer~~CEO and ~~Chief Financial Officer,~~CFO, as appropriate to allow timely decisions regarding required disclosure.

Our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective due to the material weakness in our internal control over financial reporting related to the inadequate design and implementation of controls to evaluate and monitor the accounting for revenue recognition related to license agreements.

After giving full consideration to the material weakness, and the additional analyses and other procedures that we performed to ensure that preparation and fair presentation of our financial statements included in this Quarterly Report, our management and the board of directors has concluded that our consolidated financial statements present fairly, in all material respects, our financial position, results of operations and cash flows for the periods disclosed in conformity with U.S. GAAP.

~~Plan for Remediation of Material Weakness~~

Management is implementing enhanced internal controls to remediate the material weakness. The remediation plan includes enhancement of our contract review of license agreements to confirm appropriate understanding of the terms, as well as implementation of a control designed to evaluate and monitor, at inception and on a quarterly basis, the estimated consideration to be received under license agreements for purposes of revenue recognition, analysis of deferred revenue balances, and enhanced detailed review of our revenue recognition models.

Changes in Internal Control over Financial Reporting

~~Other than the ongoing remediation efforts related to the material weakness discussed above, there~~There were no changes in our internal control over financial reporting (as ~~such term is~~ defined ~~by Rules 13a-15(f) and 15d-15(f)~~in Rule 13a‑15(f) of the Exchange Act) that occurred during the ~~most recent~~ fiscal quarter ended December 31, ~~2022~~2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

~~The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.~~32

Table of Contents

Inherent Limitations of Internal Controls

Our management, including our CEO and CFO, does not expect that our disclosure controls and procedures or our internal controls over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Due to the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Item 1A. Risk Factors

~~Risks Related to the Merger~~

~~The Exchange Ratio will not be adjusted based on the market price of our common stock or Infinity common stock, so the merger consideration at the Closing may~~There have ~~a greater or lesser value than at the time the Merger Agreement was signed.~~

At the Closing, outstanding Infinity common stock, par value $0.001 ("Infinity Common Stock") will be converted into shares of our common stock. Applying the Exchange Ratio, the former Infinity stockholders immediately before the Merger are expected to own approximately 42% of the outstanding equity of the combined company immediately following the Merger, and our stockholders immediately before the Merger are expected to own approximately 58% of the outstanding equity of the combined company immediately following the Merger, subject to certain assumptions.

~~The number of shares Infinity stockholders will be entitled to receive pursuant to the Merger Agreement will not be affected by~~been no material changes in ~~the market price of~~ our common stock or Infinity Common Stock before the completion of the Merger. Therefore, if before the completion of the Merger, the market price of our common stock increases from the market price on the date of the Merger Agreement and/or the market price of Infinity Common Stock declines from the market price on the date of the Merger Agreement, then Infinity stockholders could receive merger consideration with substantially more value for their Infinity Common Stock than the parties had negotiated when they established the Exchange Ratio. Similarly, if before the completion of the Merger the market price of our common stock declines from the market price on the date of the Merger Agreement and/or the market price of Infinity Common Stock increases from the market price on the date of the Merger Agreement, then Infinity stockholders could receive merger consideration with substantially lower value. The Merger Agreement does not include a price-based termination right.

~~If the conditions to the Merger are not satisfied or waived, the Merger may not occur.~~

Even if the Infinity stockholders adopt the Merger Agreement and approve the Infinity Merger Proposal and our stockholders approve the MEI Nasdaq Proposal, specified conditions must be satisfied or waived to complete the Merger. These conditions are set forth in the Merger Agreement. We and Infinity cannot assure you that all of the conditions to the consummation of the Merger will be satisfied or waived. If the conditions are not satisfied or waived, the Merger may not occur or the Closing may be delayed, and we and Infinity each may lose some or all of the intended benefits of the Merger.

~~The Merger may be completed even though a material adverse effect may result from the announcement of the Merger, industry wide changes or other causes.~~

In general, neither we nor Infinity are obligated to complete the Merger if there is a continuing material adverse effect affecting the other party between February 22, 2023, the date of the Merger Agreement, and the Closing. However, certain types of changes are excluded from the concept of a “material adverse effect.” Such exclusions include, but are not limited to, changes in general business or economic conditions that generally affect the industry, political conditions, acts of war or terrorism or the outbreak or escalation of armed hostilities, natural disasters, epidemics and pandemics, certain measures and responses with respect to COVID-19, changes in laws or U.S. GAAP, certain changes in the price or trading volume of our common stock or Infinity Common Stock, certain failures by us or Infinity to meet internal or analysts’ expectations or projections or the results of operations, and changes resulting from the announcement, performance or pendency of the Merger. Therefore, if any of these events were to occur, impacting us or Infinity, the other party would still be obliged to consummate the closing of the Merger. If any such adverse changes occur and we and Infinity consummate the closing of the Merger, the stock price of the combined company may suffer. This in turn may reduce the value of the Merger to our stockholders, Infinity stockholders or both.

Additional financing may not be available to the combined company when it is needed or may not be available on favorable terms. To the extent that the combined company raises additional capital by issuing equity securities, such financing will cause additional dilution to all securityholders of the combined company, including our pre-Merger stockholders and Infinity’s former stockholders. It is also possible that the terms of any new equity securities may have preferences over the combined company’s common stock. Any debt financing the combined company enters into may involve covenants that restrict its operations. These

~~Table of Contents~~

restrictive covenants may include limitations on additional borrowing and specific restrictions on the use of the combined company’s assets, as well as prohibitions on its ability to create liens, pay dividends, redeem its stock or make investments. In addition, if the combined company raises additional funds through licensing arrangements, it may be necessary to grant licenses on terms that are not favorable to the combined company.

Our directors and executive officers and Infinity directors and executive officers have interests in the Merger that are different from yours and that may influence them to support or approve the Merger without regard to your interests.

Our directors and executive officers and Infinity directors and executive officers have interests in the Merger that are different from, or in addition to, the interests of our stockholders and Infinity stockholders generally. These interests with respect to our directors and executive officers may include, among others, that Daniel P. Gold, Ph.D., Charles V. Baltic III, Thomas C. Reynolds, and Sujay R. Kango, members of our board of directors, will continue as directors after the Merger. In addition, following the Closing, David Urso (currently our Chief Operating Officer and General Counsel) is expected to serve as Chief Executive Officer of the combined company. These interests with respect to Infinity’s directors and executive officers may include, among others, (i) the acceleration of equity award vesting, (ii) that options to purchase shares of Infinity Common Stock will be converted into and become fully vested options to purchase shares of common stock of the combined company, (iii) retention payments for continued services to and through the Closing, (iv) severance payments if employment is terminated in a qualifying termination in connection with the Merger and (v) all of Infinity’s directors and executive officers are entitled to certain indemnification and liability insurance coverage pursuant to the terms of the Merger Agreement. In addition, following the Closing, Robert Ilaria, Jr., M.D. (currently Infinity’s Chief Medical Officer) is expected to serve as Chief Medical Officer of the combined company and Stéphane Peluso, Ph.D. (currently Infinity’s Chief Scientific Officer) is expected to serve as Chief Scientific Officer of the combined company.

Sujay R. Kango serves on our board of directors and Infinity's board of directors. Our board of directors and Infinity's board of directors considered, among other things, that Mr. Kango holds stock options exercisable for shares of our common stock and Infinity Common Stock.

Further, the board of directors of the combined company will include certain of our current directors and executive officers and certain of Infinity's current directors and executive officers. Following the Closing, the board of directors of the combined company is expected to be composed of eight members, consisting of Norman C. Selby (currently Infinity’s Lead Independent Director), who is expected to chair the combined company board, David Urso (currently our Chief Operating Officer and General Counsel), Daniel P. Gold, Ph.D. (currently our Chief Executive Officer), Adelene Q. Perkins (currently Infinity’s Chief Executive Officer and Chair of the board of directors of Infinity), Richard Gaynor, M.D. (currently a director of Infinity), Charles V. Baltic III (currently our Chair of the board of directors), Thomas C. Reynolds, M.D., Ph.D. (currently one of our directors) and Sujay R. Kango (currently one of our directors and a director of Infinity). The non-employee directors of the combined company will be eligible to be compensated pursuant to our non-employee director compensation policy that is expected to remain in place following the Effective Time.

Our board of directors and Infinity's board of directors were aware of and considered those interests, among other matters, in reaching their decisions to approve and adopt the Merger Agreement and approve the Merger, and in the case of the Infinity board of directors, recommend the approval of the Merger Agreement to Infinity’s stockholders. These interests, among otherrisk factors ~~may have influenced our board of directors and Infinity's board of directors to support or approve the Merger.~~

Applying the Exchange Ratio, the former Infinity stockholders immediately before the Merger are expected to own approximately 42% of the outstanding equity of the combined company immediately following the Merger, and our stockholders immediately before the Merger are expected to own approximately 58% of the outstanding equity of the combined company immediately following the Merger, subject to certain assumptions. If the combined company is unable to realize the full strategic and financial benefits currently anticipated from the Merger, our stockholders and Infinity stockholders will have experienced substantial dilution of their ownership and voting interests in the respective companies without receiving any commensurate benefit, or only receiving part of the commensurate benefit to the extent the combined company is able to realize only part of the strategic and financial benefits currently anticipated from the Merger.

~~If the Merger is not completed, our stock price may fluctuate significantly.~~

The market price of our common stock is subject to significant fluctuations. During the 12-month period ended April 14, 2023, the closing sales price of our common stock on The Nasdaq Capital Market ranged from a high of $13.00 on June 27, 2022 to a low of $4.20 on February 24, 2023.

~~Table of Contents~~

Market prices for securities of pharmaceutical, biotechnology and other life science companies have historically been particularly volatile. In addition, the market prices of our common stock and Infinity Common Stock will likely be volatile based on whether stockholders and other investors believe that we and Infinity can complete the Merger or otherwise raise additional capital to support the combined company’s operations if the Merger is not consummated and another strategic transaction cannot be identified, negotiated and consummated in a timely manner, if at all. The volatility of the market prices of our common stock and Infinity Common Stock are exacerbated by low trading volume. Additional factors that may cause the market prices of our common stock and Infinity Common Stock, respectively, to fluctuate include:

•

the initiation of, material developments in, or conclusion of litigation to enforce or defend its intellectual property rights or defend against claims involving the intellectual property rights of others;

•

~~the entry into, or termination of, key agreements, including commercial partner agreements;~~

•

~~announcements by commercial partners or competitors of new commercial products, clinical progress or lack thereof, significant contracts, commercial relationships or capital commitments;~~

•

~~the introduction of technological innovations or new therapies that compete with its future products;~~

•

~~the loss of key employees;~~

•

~~future sales of its common stock;~~

•

~~general and industry-specific economic conditions that may affect its research and development expenditures;~~

•

~~the failure to meet industry analyst expectations; and~~

•

~~period-to-period fluctuations in financial results.~~

Moreover, the stock markets in general have at times experienced substantial volatility that has often been unrelated to the operating performance of individual companies. These broad market fluctuations may also adversely affect the trading prices of our common stock and Infinity Common Stock. In the past, following periods of volatility in the market price of a company’s securities, stockholders have often instituted class action securities litigation against such companies.

Covenants in the Merger Agreement impede our ability and Infinity's ability to make acquisitions during the pendency of the Merger, subject to specified exceptions. As a result, if the Merger is not completed, we may be at a disadvantage to our competitors during that period. In addition, while the Merger Agreement is in effect, each party is generally prohibited from soliciting, initiating, inducing, encouraging, or facilitating any inquiries, proposals or offers that constitute or could reasonably be expected to lead to certain transactions involving a third party, including a merger, sale of assets or other business combination, subject to specified exceptions. Any such transactions could be favorable to our stockholders, but we may be unable to pursue them.

~~Certain provisions of the Merger Agreement may discourage third parties from submitting competing proposals, including proposals that may be superior to the Merger.~~

The terms of the Merger Agreement prohibits us and Infinity from soliciting or engaging in discussions with third parties regarding alternative acquisition proposals, except in limited circumstances when such party’s board of directors determines in good faith that an unsolicited acquisition proposal constitutes or could reasonably be expected to lead to a superior proposal and that failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties under applicable law. In addition, if the Merger Agreement is terminated by us or Infinity under certain circumstances, including because of a decision by either company’s board of directors to accept a superior proposal, such company would be required to pay the other a termination fee. This termination fee may discourage third parties from submitting alternative takeover proposals to either company or its stockholders and may cause such company’s board of directors to be less inclined to recommend an alternative proposal.

~~The financial analyses, estimates and forecasts considered by us and Infinity in connection with the Merger may not be realized.~~

Our unaudited prospective financial information and Infinity's unaudited prospective financial information considered by us and Infinity in connection with the Merger was not prepared with a view toward public disclosure, and such information and the estimated synergies were not prepared with a view toward compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The estimates and assumptions underlying the unaudited prospective financial information and estimated synergies involve judgments with respect to, among other things, future economic, competitive, regulatory and financial market conditions, future tax rates and future business decisions which may not be realized and that are inherently subject to significant business, economic, competitive and regulatory uncertainties and contingencies, including, among others, risks and uncertainties, all of which are difficult to predict and many of which are beyond our and/or Infinity's control. In addition, the unaudited prospective financial information and estimated synergies will be affected by our or Infinity’s, as applicable, ability to achieve strategic goals, objectives and targets over the

~~Table of Contents~~

applicable periods. As a result, there can be no assurance that the underlying assumptions will prove to be accurate or that the projected results or synergies will be realized, and actual results or synergies likely will differ, and may differ materially, from those ~~reflected~~included in ~~the unaudited prospective financial information and the estimated synergies, whether or not the Merger is completed, which could have an adverse effect on~~ our ~~and Infinity’s business, financial condition and result of operations.~~

~~The announcement and pendency of the Merger, whether or not consummated, may adversely affect the trading price of our common stock and our business prospects.~~

The announcement and pendency of the Merger, whether or not consummated, may adversely affect the trading price of our common stock and our business prospects. In the event that the Merger is not completed, the announcement of the termination of the Merger Agreement may also adversely affect the trading price of our common stock and our business prospects.

Failure to consummate the Merger may result in either us or Infinity paying a termination fee to the other party and could harm the common stock price of the party obligated to pay the termination fee and such party’s future business and operations.

The Merger will not be consummated if the conditions precedent to the consummation of the transaction are not satisfied or waived, or if the Merger Agreement is terminated in accordance with its terms. If the Merger is not consummated, we and Infinity, as applicable, are subject to the following risks:

•

if the Merger Agreement is terminated under certain circumstances, we may be required to pay Infinity a termination fee of $4,000,000 and/or reimburse Infinity’s reasonable out of pocket fees and expenses incurred in connection with the Merger Agreement and the transaction contemplated thereby up to a maximum of $1,000,000;

•

if the Merger Agreement is terminated under certain circumstances, Infinity may be required to pay us a termination fee of $2,900,000 and/or reimburse our reasonable out of pocket fees and expenses incurred in connection with the Merger Agreement and the transaction contemplated thereby up to a maximum of $1,000,000; and

•

~~the price of either party’s common stock may decline and remain volatile.~~

If the Merger does not close for any reason, either party’s board of directors may elect to, among other things, attempt to complete another strategic transaction, attempt to sell or otherwise dispose of such company’s various assets, dissolve or liquidate its assets, declare bankruptcy or seek to continue to operate its business. If either company seeks another strategic transaction or attempts to sell or otherwise dispose of its various assets, there is no assurance that it will be able to do so, that the terms would be equal to or superior to the terms of the Merger or as to the timing of such transaction. If either company decides to dissolve and liquidates its assets, such company would be required to pay all of its debts and contractual obligations, and to set aside certain reserves for potential future claims, and there can be no assurance as to the amount or timing of available cash left to distribute to stockholders after paying its debts and other obligations and setting aside funds for reserves.

~~If the Merger is not consummated, each of us and Infinity would need to determine whether to continue its business, consummate another strategic transaction, or dissolve and liquidate its assets.~~

If the Merger is not consummated, we and Infinity, as applicable, may be unable to retain the services of key remaining members of our respective management teams and, as a result, may be unable to seek or consummate another strategic transaction, properly dissolve and liquidate its assets or continue its business. If the Merger is not successfully consummated, our board of directors and Infinity's board of directors may dissolve or liquidate the respective company’s assets to pursue a dissolution and liquidation. In such an event, the amount of cash available for distribution to our stockholders or Infinity’s stockholders, as applicable, will depend heavily on the timing of such transaction or liquidation.

If the Merger does not close for any reason, the board of directors of Infinity may elect to, among other things, dissolve or liquidate its assets, which may include seeking protection from creditors in a bankruptcy proceeding. If Infinity decided to dissolve and liquidate its assets, it would be required to pay all of its debts and contractual obligations, and to set aside certain reserves for potential future claims, and there can be no assurances as to the amount or timing of available cash left to distribute to stockholders after paying its debts and other obligations and setting aside funds for reserves.

In the event of a dissolution and liquidation, the amount of cash available for distribution to our stockholders or Infinity’s stockholders, as applicable, will depend heavily on the timing of such decision and, ultimately, such liquidation, since the amount of cash available for distribution continues to decrease as we or Infinity, as applicable, fund our respective operations in preparation for the consummation of the Merger. Further, the Merger Agreement contains certain termination rights for each party, and provides that, upon termination under specified circumstances, either party may be required to pay the other a termination fee, which would further decrease such company’s’ available cash resources. If either party’s board of directors were to approve and recommend, and its stockholders were to approve, a dissolution and liquidation, such company would be required under Delaware corporate law to pay its outstanding obligations, as well as to make reasonable provision for contingent and unknown obligations, prior to making any distributions in liquidation to its stockholders. As applicable, our and Infinity’s commitments and contingent liabilities may include (i)

~~Table of Contents~~

regulatory and clinical obligations remaining under our respective clinical trials; (ii) obligations under its employment, separation and retention agreements with certain employees that provide for severance and other payments following a termination of employment occurring for various reasons, including a change in control; and (iii) potential litigation against such company, and other various claims and legal actions arising in the ordinary course of business. As a result of this requirement, a portion of our assets and Infinity’s assets, as applicable, may need to be reserved pending the resolution of such obligations. In addition, either company may be subject to litigation or other claims related to a dissolution and liquidation of such company. If a dissolution and liquidation were pursued, such company’s board of directors, in consultation with its advisors, would need to evaluate these matters and make a determination about a reasonable amount to reserve. Accordingly, holders of our common stock and Infinity Common Stock, as applicable, could lose all or a significant portion of their investment in the event of either companies liquidation, dissolution or winding up.

~~We or Infinity may waive one or more of the conditions to the Merger, and may do so without re-soliciting stockholder approval.~~

We or Infinity may agree to waive, in whole or in part, some of the conditions to each party’s obligations to complete the Merger, to the extent permitted by applicable law. For example, it is a condition to our and Infinity’s respective obligations to close the Merger that certain of the representations and warranties of the other party are true and correct in all respects as of the date of the Closing (the “Closing Date”), except where the failure of such representations and warranties to be true and correct would not have a material adverse effect. However, if the board of directors of either party determines that it is in the best interests of the stockholders of that company to waive any such breach by the other party, then such board of directors may elect to waive that condition.

In the event of a waiver of a condition, our board of directors and Infinity's board of directors will evaluate the materiality of any such waiver to determine whether amendment of this joint proxy statement/prospectus and re-solicitation of proxies is necessary. In the event that the boards of directors of the waiving party, in its own reasonable discretion, determines any such waiver is not significant enough to require re-solicitation of its stockholders, it will have the discretion to cause the Merger to be completed without seeking further stockholder approval, which decision may have a material adverse effect on the stockholders of the combined company following the Merger. For example, the market could react negatively to such information, which may cause a substantial decline in the price of the common stock of the combined company following the Merger.

Notwithstanding the foregoing, certain closing conditions may not be waived due to applicable law, or otherwise. The following closing conditions may not be waived: receipt of the requisite stockholder approvals; the effectiveness of the registration statement of which this joint proxy statement/prospectus forms a part; and the absence of any order or injunction that has the effect of prohibiting the consummation of the Merger. The foregoing closing conditions are the only closing conditions to the Merger that may not be waived. All other closing conditions to the Merger may be waived by us and/or Infinity, as applicable.

The Merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) Code. However, Infinity has not sought and does not intend to seek a ruling from the IRS or an opinion of counsel regarding the intended tax treatment of the Merger. Consequently, there can be no assurance that the IRS will not challenge the intended tax treatment of the Merger and, if challenged, that a court would not sustain the IRS’s position. In the event that the Merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, each U.S. Holder would recognize gain or loss upon the exchange of shares of Infinity Common Stock for our common stock in the Merger equal to the difference between the fair market value of the shares of our common stock received in exchange for the shares of Infinity Common Stock (plus any cash received in lieu of a fractional share) and such U.S. Holder’s adjusted tax basis in the shares of Infinity Common Stock surrendered. Each Infinity stockholder is urged to consult with his, her or its own tax advisor with respect to the tax consequences of the Merger.

~~Lawsuits could delay or prevent the Merger.~~

Putative stockholder complaints, including stockholder class action complaints, and other complaints may be threatened or filed against us, Infinity, and/or our respective boards of directors in connection with the transactions contemplated by the Merger Agreement. We, Infinity, and/or our respective boards of directors may not be successful in defending against any such claims. The outcome of litigation is uncertain, and any such lawsuits that may be threatened or filed against us, Infinity, and/or our respective boards of directors could delay or prevent the Merger from becoming effective or from becoming effective within the intended timeframe, divert the attention of our and/or Infinity’s management and employees from our respective day-to-day businesses and otherwise adversely affect their respective financial conditions.
