Marker Therapeutics, Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE FISCAL YEARS DECEMBER 31, 2024 AND 2023

NOTE 1: NATURE OF OPERATIONS

Marker Therapeutics, Inc., a Delaware corporation (the “Company” or “we”), is a clinical-stage immuno-oncology company specializing in the development and commercialization of novel T cell-based immunotherapies for the treatment of hematological malignancies and solid tumor indications. The Company’s multi antigen recognizing (“MAR”)-T cell technology is based on the selective expansion of non-engineered, tumor-specific T cells that recognize tumor associated antigens, which are tumor targets, and kill tumor cells expressing those targets. These T cells are designed to recognize multiple tumor targets to produce broad spectrum anti-tumor activity. The Company was incorporated in Nevada in 1992 and reincorporated in Delaware in October 2018.

Purchase Agreement with Cell Ready; Manufacturing

On June 26, 2023, the Company completed the previously announced transaction with Cell Ready, LLC (“Cell Ready”) pursuant to a Purchase Agreement (the “Cell Ready Purchase Agreement), dated May 1, 2023, by and between the Company and Cell Ready. Mr. John Wilson was a member of the Company’s board of directors at the time of the Cell Ready Purchase Agreement and through December 31, 2024 and is serving as the CEO of Cell Ready, therefore Cell Ready is a related party. Mr. Wilson resigned as a director of the Company on January 24, 2025. Pursuant to the Cell Ready Purchase Agreement, effective as of the Closing Date, the Company (i) assigned to Cell Ready the leases for the Company’s two manufacturing facilities in Houston, Texas (the “Manufacturing Facilities”), (ii) sold to Cell Ready all of the equipment and leasehold improvements at the Manufacturing Facilities and (iii) assigned to Cell Ready its rights, title and interest in the Company’s Master Services Agreement for Product Supply (the “MSA”), dated April 7, 2023, by and between the Company, Cell Ready and Indapta Therapeutics, Inc., as well as its rights, title and interest in any contracts related to the equipment and Manufacturing Facilities (collectively, the “Purchased Assets”). Cell Ready acquired the Purchased Assets for total consideration of $19.0 million. In connection with the purchase of the Manufacturing Facilities, Cell Ready also extended offers of employment to approximately 50 of the Company’s former employees in its manufacturing, development, quality, and regulatory affairs functions.

The Purchased Assets constituted a significant disposition. Based upon the magnitude of the disposition and because the Company is exiting certain manufacturing operations, the disposition represents a significant strategic shift that will have a material effect on the Company’s operations and financial results. Accordingly, the assets sold meet the definition of a discontinued operation, as defined by Accounting Standards Codification (“ASC”) 205-20 - Discontinued Operations. See additional discussion at Note 6.

Following the closing of the Cell Ready Purchase Agreement, the Company no longer operates a cGMP manufacturing facility and instead relies on third parties for the clinical and, once approved, commercial manufacture of our product candidates. As such, on February 22, 2024, the Company entered into a Master Services Agreement for Product Supply (the “MSA”) with Cell Ready for the provision of various products and services by Cell Ready pursuant to work orders that may be entered into from time to time. Cell Ready is a contract development and manufacturing organization (CDMO). The MSA contains customary representations, warranties and indemnification provision. The initial term of the MSA is three years and may be extended upon the mutual written agreement of the parties. Either party may terminate the MSA (a) for material breach by the other party if such breach has not been cured within 30 days following notice of termination or (b) if the other party is the subject of an insolvency event.

Additionally, the Baylor College of Medicine (“BCM”) continues to supply the Company with products and the Company is working with both of its existing qualified contract manufacturers as it continues its clinical trials. Furthermore, in anticipation of the commencement of the Company’s larger pivotal trial for Lymphoma in 2026, as well as the eventual need for commercial scale production, the Company intends to evaluate and qualify additional potential third-party manufacturing partners to provide potential multiple sources of clinical and commercial supply.

However, there is no guarantee that the Company will or has properly estimated its required manufacturing capacities or that the third parties on which it relies to manufacture products will be able or willing to perform on proposed timelines or to meet the Company’s manufacturing demands, if at all. If any third-party vendors experience disruptions or otherwise cease or substantially reduce the amount of products they are willing to supply, the Company’s business and operations could be adversely affected.

Organizational Changes

In 2023, the Company implemented changes to its organizational structure due to the transaction with Cell Ready and to reduce operational costs. In connection with these changes, the Company reduced headcount, including the separation of its former Chief Executive Officer, Peter Hoang, in May 2023 and its former Chief Accounting Officer, Michael Loiacono, in June 2023. During the second quarter of 2023, the Company recorded $0.9 million of severance and termination-related costs. The payments of these costs were completed in July of 2023. Effective May 1, 2023, the Company’s board of directors appointed Dr. Juan Vera as the Company’s President and Chief Executive Officer.

Effective June 30, 2023, the board of directors appointed Eliot M. Lurier as the Company’s Interim Chief Financial Officer, whereby Mr. Lurier provided consulting services to the Company pursuant to a consulting between the Company and Danforth Advisors, LLC (“Danforth”) and received no compensation directly from the Company. On November 17, 2023, the Company terminated the consulting agreement between the Company and Danforth, effective January 16, 2024.

On November 17, 2023, Mr. Lurier ceased serving as the Company’s Interim Chief Financial Officer and Dr. Vera was appointed as the Company’s Principal Financial and Accounting Officer.

NOTE 2: FINANCIAL CONDITION, GOING CONCERN AND MANAGEMENT PLANS

As of December 31, 2024, the Company had cash and cash equivalents of approximately$19.2 million. The Company’s activities since inception have consisted principally of acquiring product and technology rights, raising capital, and performing research and development. Successful completion of the Company’s development programs and, ultimately, the attainment of profitable operations are dependent on future events, including, among other things, its ability to access potential markets; secure financing; successfully progress its product candidates through preclinical and clinical development; obtain regulatory approval of one or more of its product candidates; maintain and enforce intellectual property rights; develop a customer base; attract, retain and motivate qualified personnel; and develop strategic alliances and collaborations. From inception, the Company has been funded by a combination of equity, debt financings and grants.

In August 2021, the Company entered into a Controlled Equity Offering SM Sales Agreement (the “ATM Agreement”) with Cantor Fitzgerald & Co. and RBC Capital Markets, LLC (the “Sales Agents”), pursuant to which the Company could offer and sell, from time to time at its sole discretion through the Sales Agents, shares of its common stock having an aggregate offering price of up to $75.0 million. Any shares of its common stock sold were issued pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-258687), which the SEC declared effective on August 19, 2021. However, our use of the shelf registration statement on Form S-3 was limited for so long as we were subject to General Instruction I.B.6 of Form S-3, which limited the amounts that we could sell under the registration statement and in accordance with the ATM agreement. The Sales Agents were entitled to compensation under the Sales Agreement at a commission rate equal to 3.0% of the gross sales price per share sold under the ATM Agreement, and we provided each of the Sales Agents with indemnification and contribution rights. During the year ended December 31, 2024, the Company sold 8,178 shares of its common stock under the ATM Agreement for proceeds of $0.04 million. On June 10, 2024, the Company provided notice of its termination of the ATM Agreement with Cantor Fitzgerald & Co. and RBC Capital Markets, LLC. The Company is not subject to any termination penalties related to the termination of the ATM Agreement.

In November 2024, the Company entered into an At The Market Offering Agreement, or the Sales Agreement, with H.C. Wainwright & Co. LLC, relating to the sale of shares of its common stock having an agreement offering price of up to $11,431,713 from time to time through H.C. Wainwright & Co. LLC. Any shares of common stock sold will be issued pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-283512), which the SEC declared effective on December 6, 2024. However, the Company’s use of the shelf registration statement on Form S-3 will be limited for so long as it is subject to General Instruction I.B.6 of Form S-3, which limits the amounts that the Company may sell under the registration statement and in accordance with the ATM agreement. H.C. Wainwright & Co. LLC will be entitled to compensation under the Sales Agreement at a commission rate equal to 3.0% of the gross sales price per share sold under the ATM Agreement, and the Company’ has provided H.C. Wainwright & Co. LLC with indemnification and contribution rights.

In December 2022, the Company entered into a purchase agreement, or the Purchase Agreement, with Lincoln Park Capital Fund, LLC, or Lincoln Park, which provides that, upon the terms and subject to the conditions of the agreement, the Company has the right, but not the obligation, to sell to Lincoln Park up to $25,000,000 of shares of its common stock, or the Purchase Shares, from time to time over a 24-month term. For the year ended December 31, 2024, the Company did not sell any shares of its common stock under the Purchase Agreement. In January 2023, Lincoln Park was issued 180,410 shares of stock as a commitment fee at a value of $0.5 million. On February 29, 2024, the Company terminated the Purchase Agreement with Lincoln Park effective March 1, 2024.

On December 19, 2024, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”), pursuant to which the Company issued and sold in a private Placement the following securities: (i)1,783,805 shares of common stock, (ii) Series B Warrants, or Pre-Funded Warrants, to purchase an aggregate of 3,247,445 shares of common stock in lieu of shares of common stock and (iii) Series A Warrants, or Private Placement Warrants, to purchase an aggregate of 5,031,250 shares of common stock. The purchase price per share of common stock and accompanying Private Placement Warrant to purchase a share of common stock was$3.20, and the purchase price per Pre-Funded Warrant and accompanying Private Placement Warrant to purchase a share of common stock was$3.199.

Net proceeds from the sale of securities in the Private Placement was approximately$14.9 million, which does not include any proceeds that may be received upon exercise of any warrants issued in the Private Placement. Both the Pre-Funded Warrants and the Private Placement Warrants are not exercisable until the Company obtains shareholder approval. On March 21, 2025, the Company obtained shareholder approval for the exercise of such warrants. The transaction closed on December 23, 2024.

The Company expects to continue to incur substantial losses over the next several years during its development phase.

Based on the Company’s lack of recurring revenues, anticipated uses of cash and historical recurring cash losses from operating activities, and cash and cash equivalents as of December 31, 2024, the Company anticipates that it will be able to fund its operating expenses and capital expenditure requirements into the first quarter of 2026, assuming no additional grant funds are received. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern.

Management currently plans to raise additional capital through the issuance of common shares and receipt of additional grant funds, which could enable the Company to fund its operating expenses and capital expenditure requirements beyond the first quarter of 2026, although no assurance can be given that such capital or existing awarded grants will be earned or future grants will be awarded. The Company’s future cash requirements are based on the Company’s clinical and research and development plans, timing expectations related to the progress of its programs, and is subject to the Company’s ability to effectively manage its costs, raise additional capital, and receive additional grant funds.

The Company’s assumptions may prove to be wrong, and the Company could utilize its available capital resources sooner than it currently expects. Furthermore, the Company’s operating plan may change, and it may need additional funds sooner than planned in order to meet operational needs and capital requirements for product development and commercialization. Because of the numerous risks and uncertainties associated with the development and commercialization of the Company’s product candidates and the extent to which the Company may enter into additional collaborations with third parties to participate in their development and commercialization, the Company is unable to estimate the amounts of increased capital outlays and operating expenditures associated with its current and anticipated clinical trials. The Company’s future funding requirements will depend on many factors, as it:

The Company’s consolidated financial statements have been prepared on a going concern basis, which implies that the Company will continue to realize its assets and discharge its liabilities in the normal course of business. The Company’s financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

In addition to the foregoing, the current macro-economic environment of decades-high inflation and concerns about an economic recession in the United States or other major markets have resulted in, among other things, volatility in the capital markets that may have the effect of reducing the Company’s ability to access capital, which could in the future negatively affect the Company’s liquidity.

In addition, a recession or market correction due to these factors could materially affect the Company’s business and the value of its common stock.

NOTE 3: SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and pursuant to the rules and regulations of the Securities Exchange Commission (“SEC”). Any reference in these footnotes to applicable guidance is meant to refer to the authoritative U.S. generally accepted accounting principles (“GAAP”) as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Principles of Consolidation

These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Marker Cell Therapy, Inc. and GeneMax Pharmaceuticals Inc. – a dormant subsidiary that wholly owns GeneMax Pharmaceuticals Canada, Inc. All significant intercompany balances and transactions are eliminated upon consolidation.

Use of Estimates

Preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Accordingly, actual results may differ materially from those estimates. Management considers many factors in selecting appropriate financial accounting policies, controls, and in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. Estimates are used in the following areas, among others: stock-based compensation expense and income taxes.

Cash, Cash Equivalents and Credit Risk

The Company considers highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents at December 31, 2024 consisted of cash and certificates of deposit in institutions in the United States. Balances at certain institutions have exceeded Federal Deposit Insurance Corporation insured limits and U.S. government agency securities.

The Company maintains cash in accounts which are in excess of the Federal Deposit Insurance Corporation (“FDIC”) insured limits of $250,000. As of December 31, 2024 and December 31, 2023, the Company had approximately $1.1 million and $1.4 million, respectively in cash at financial institutions. As of December 31, 2024, the Company had approximately $18.1 million in U.S. government agency securities.

In the event cash is received from grants in advance of incurring qualifying costs, it is recorded as restricted cash until it is earned and recorded to grant income.

The Purchased Assets sold to Cell Ready pursuant to the Cell Ready Purchase Agreement constituted a significant disposition and as such, the Company concluded that the disposition of its Purchased Assets represented a strategic shift that had a major effect on its operations and financial results. Therefore, the Purchased Assets, related party revenue, service revenue and related expenses are classified as discontinued operations for all periods presented herein. See Note 6 for further information.

Patents and Patent Application Costs

Although the Company believes that its patents and underlying technology have continuing value, the amount of future benefits to be derived from the patents is uncertain. Patent costs are, therefore, expensed as incurred.

Stock-Based Compensation

The Company incurs stock-based compensation expense related to the issuance of common stock and stock options. The Company estimates the fair value of stock options granted using the Black-Scholes option pricing model. The Black-Scholes option pricing model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected stock price volatility and expected option life:

Expected Term — The expected life of stock options was estimated using the “simplified method,” as the Company has limited historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior for its stock options grants. The simplified method is based on the average of the vesting tranches and the contractual life of each grant.

Expected Volatility — The Company computes stock price volatility over expected terms based on its historical common stock trading prices.

Risk-Free Interest Rate — The Company bases the risk-free interest rate on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term.

Expected Dividend — The Company has never declared or paid any cash dividends on its common shares and does not plan to pay cash dividends in the foreseeable future, and, therefore, uses an expected dividend yield of zero in its valuation models.

The Company amortizes the fair value of the awards expected to vest on a straight-line basis over the requisite service period of the awards. The Company recognizes fair value of stock options granted to nonemployees as stock-based compensation expense over the period in which the related services are received as if the Company had paid cash for those services. Forfeitures are accounted for as incurred.

Research and Development Costs

Research and development expenses consist of costs associated with clinical trial programs. Costs incurred by third parties are expensed as the contracted work is performed. The Company accrues for costs incurred as the services are being provided by monitoring the status of the clinical trial or project and the invoices received from its external service providers. The Company estimates depend on the timeliness and accuracy of the data provided by the vendors regarding the status of each project and total project spending. The Company adjusts its accrual as actual costs become known. Where contingent milestone payments are due to third parties under research and development arrangements, the milestone payment obligations are expensed when the milestone events are achieved.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax balances. Potential deferred tax assets and liabilities are measured using enacted tax rates expected to apply to the taxable income in the years in which those differences are expected to be recovered or settled. The effect on potential deferred tax assets and liabilities of a change in tax rates is recognized in the statement of operations in the period that includes the date of allowances against deferred tax assets.

Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards. As of December 31, 2024 and 2023, no liability for unrecognized tax benefits was required to

be reported. The guidance also discusses the classification of related interest and penalties on income taxes. The Company’s policy is to record interest and penalties on uncertain tax positions as a component of income tax expense. No interest or penalties were recorded during the years ended December 31, 2024 and 2023.

Grant Income

Grant Income represents funding under cost reimbursement programs from government agencies and non-profit foundations for qualified research and development activities performed by the Company. In applying the provisions of ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), the Company determined that grants and awards are out of the scope of ASC 606 because the funding entities do not meet the definition of a “customer”, as defined by ASC 606, as there is not considered to be a transfer of control of goods or services. With respect to each grant or award, the Company determines if it has a collaboration in accordance with ASC Topic 808, Collaborative Arrangements (“ASC 808”). For grant and awards outside the scope of ASC 808, the Company applies either ASC 606 or IAS 20 by analogy depending on if the arrangement is considered an exchange or non-exchange transaction, respectively. Under both accounting frameworks, revenue is recognized when the Company incurs expenses related to the grants for the amount the Company is entitled to under the provisions of the contract. During the two years ended December 31, 2024, the Company did not participate in any collaboration agreements.

Loss per Common Share

Basic loss per share includes only the weighted average common shares outstanding, without consideration of potentially dilutive securities. Diluted loss per share includes the weighted average common shares outstanding and any potentially dilutive common stock equivalent shares in the calculation.

Segment Reporting

The Company adopted Accounting Standard Update (“ASU”) 2023-07, Segment Reporting (Topic 280) – Improvements to Reportable Segment Disclosures, as of January 1, 2024. See the section Recently Adopted Accounting Standards below for more information.

Operating segments are defined as components of an entity for which separate discrete financial information is made available and that is regularly evaluated by the chief operating decision maker (“CODM”) in making decisions regarding resource allocation and assessing performance. The Company is a clinical-stage immuno-oncology company specializing in the development and commercialization of novel T cell-based immunotherapies for the treatment of hematological malignancies and solid tumor indications. The Company’s operations are organized and reported as a single reportable segment, which includes all activities related to the discovery, development, and commercialization of its products. The Company’s CODM, its chief executive officer, reviews operating results on an aggregate basis and manages the operations as a single operating segment.

The accounting policies of the Company’s single operating and reportable segment are the same as those described in the summary of significant accounting policies. The measure of segment assets is reported on the consolidated balance sheets as total assets. The CODM evaluates performance and allocates resources based on consolidated net income (loss) that also is reported on the consolidated statements of operations as net loss, and consolidated cash used in operations. The Company’s significant expenses are consistent with the expenses presented on the consolidated statement of operations. The CODM makes operating decisions based on the availability of cash and the allocation of cash to the required expenditures. Expenses are not regularly provided to the CODM on a more disaggregated basis for purposes of assessing segment performance and deciding how to allocate resources.

New Accounting Standards

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that the Company adopts as of the specified effective date. Unless otherwise discussed, the Company does not believe that the impact of recently issued standards that are not yet effective will have a material impact on its financial position or results of operations upon adoption.

Recently Adopted Accounting Standards

Improvements to Reportable Segment Disclosures

In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU requires disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker, among other provisions. Effective January 1, 2024, the Company adopted the new standard on a retrospective basis for annual periods, and interim periods beginning the first quarter of 2025. The Company does not believe the impact of the new guidance and related codification improvements had a material impact to its financial position, results of operations and cash flows.

Recently Issued Accounting Standards Not Yet Adopted

Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the annual periods beginning the year ended December 31, 2025. Early adoption is permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. We do not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures

In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures, to improve transparency in financial reporting by requiring entities to present more detailed information about the nature of expenses included within the Income Statement. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. The Company is in the process of assessing the impact of ASU 2024-03 on its disclosures.

NOTE 4: NET LOSS PER SHARE APPLICABLE TO COMMON SHAREHOLDERS

Basic loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the reporting period. Diluted loss per common share is computed similarly to basic loss per common share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock.

The following table sets forth the computation of net loss per share for the years ended December 31, 2024 and 2023, respectively:

The following securities, rounded to the thousand, were not included in the diluted net loss per share calculation because their effect was anti-dilutive for the periods presented:

NOTE 5: OTHER RECEIVABLE

Qualifying grant income earned in advance of cash received from grants is recognized as revenue and recorded as other receivable. The Company recorded $4.4 million of grant income related to the CPRIT grant for the year ended December 31, 2024. At December 31, 2024, the Company recorded $2.1 million of grant income receivable related to the CPRIT grant.

Additionally, the Company recorded $0.5 million and $1.0 million of grant income related to the FDA and SBIR grants related to MT - 401, respectively, for the year ended December 31, 2024. At December 31, 2024, the Company recordednil and $0.2 million of grant income receivable related to the FDA and SBIR grants, respectively.

The Company received $0.2 million of funds from SBIR in February 2025.

The Company also recorded approximately $6,000 and $7,000 of grant income related to the National Institutes of Health grants related to the advancement of MT-601 in patients with pancreatic cancer.

The Company received $6,000 and $7,000, respectively, from the National Institutes of Health grants related to the advancement of MT-601 in patients with pancreatic cancer.

NOTE 6: DISCONTINUED OPERATIONS

As discussed in Note 1, on June 26, 2023, the Company completed the previously announced transaction with Cell Ready for cash consideration of $19.0 million, resulting in derecognition of the Purchased Assets and a gain on sale of approximately $8.7 million, net of $63,000 in tax.

There wereno assets and liabilities classified in discontinued operations as of December 31, 2024 and 2023, respectively.

The Company had no activity related to discontinued operations for the year ended December 31, 2024. Net loss from discontinued operations consists of the following for the year ended December 31, 2023, excluding the gain on disposal:

The following table summarizes our cash flows related to discontinued operations for the year ended December 31, 2023:

Related Party Service Revenue

In April 2022, the Company entered into a binding services agreement (“Wilson Wolf Agreement”) with Wilson Wolf Manufacturing Corporation (“Wilson Wolf”). Mr. John Wilson was a member of the Company’s board of directors at the time of the agreement and is serving as the CEO of Wilson Wolf. Wilson Wolf is in the business of creating products and services intended to simplify and expedite the transition of cell therapies and gene-modified cell therapies to mainstream society (the “Wilson Wolf Mission”). Pursuant to the Wilson Wolf Agreement, Wilson Wolf made a cash payment to the Company in the amount of $8.0 million, as consideration for certain training and research services.

In March 2023, the Company recognized the final $2.5 million of revenue pursuant to this $8.0 million agreement and an additional $1.0 million because the work was completed within one year from the onset of the Wilson Wolf Agreement, achieving the agreed milestone.

In December 2024, the Company received notice of an additional $9.5 million grant from CPRIT to support the clinical investigation of MT-601 in patients with pancreatic cancer. Both CPRIT grants contain identical terms surrounding intellectual property and revenue sharing.

Per the CPRIT grant agreements, the Company will retain ownership over any intellectual property developed under the contracts (the “Project Results”). With respect to non-commercial use of any Project Results, the Company agreed to grant to CPRIT a nonexclusive, irrevocable, royalty-free, perpetual, worldwide license with the right to sublicense any necessary additional intellectual property rights to exploit all Project Results by CPRIT, other governmental entities and agencies of the State of Texas, and private or independent institutions of higher education located in Texas, solely for academic, research, and other non-commercial purposes.

These payments will continue up to and until CPRIT receives an aggregate amount of 400% of the sum of all monies paid to the Company by CPRIT under the grant agreements. If the Company is required to obtain a license from a third party to sell any such product, the revenue sharing percentages may be reduced.

The effects of temporary differences that give rise to significant portions of the deferred tax assets as of December 31, 2024 and 2023 are as follows:

The Company assesses the likelihood that deferred tax assets will be realized. To the extent that realization is not likely, a valuation allowance is established. Based upon the history of losses, management believes that it is more likely than not that future benefits of deferred tax assets will not be realized and has established a full valuation allowance for the years ended December 31, 2024 and 2023.

The Company has approximately $138.3 million of federal and $38.8 million of state Net Operating Losses (“NOL”s) that may be available to offset future taxable income, if any. The federal net operating loss carryforwards of $38.4 million, if not utilized, will expire between 2030 and 2037. The federal net operating loss carryforwards of $99.9 million generated in 2018 and thereafter are subject to an 80% limitation on taxable income, do not expire and will carry forward indefinitely. The state net operating loss carryforwards of $21.9 million, if not utilized, will begin to expire in 2035. The state net operating loss carryforwards of $16.9 million generated in 2018 and thereafter are subject to an 80% limitation on taxable income, do not expire and will carry forward indefinitely.

Effective for tax years beginning after December 31, 2021, taxpayers are required to capitalize any expenses incurred that are considered incidental to research and experimentation (R&E) activities under IRC Section 174. While taxpayers historically had the option of deducting these expenses under IRC Section 174, the December 2017 Tax Cuts and Jobs Act mandates capitalization and amortization of R&E expenses for tax years beginning after December 31, 2021. Expenses incurred in connection with R&E activities in the US must be amortized over a 5-year period if incurred, and R&E expenses incurred outside the US must be amortized over a 15-year period. R&E activities are broader in scope than qualified research activities considered under IRC Section 41 (relating to the research tax credit). For the year ended December 31, 2024, and 2023, the Company performed an analysis based on available guidance and determined that it will continue to be in a loss position even after the required capitalization and amortization of its R&E expenses. The Company will continue to monitor this issue for future developments, but it does not expect R&E capitalization and amortization to require it to pay cash taxes now or in the near future.

The Company’s income tax returns for 2021 to 2023 are still open and subject to audit. In addition, net operating losses arising from prior years are also subject to examination at the time they are utilized in future years.

For the years ended December 31, 2024, and 2023, the expected tax expense (benefit) from continuing operations based on the U. S. federal statutory rate is reconciled with the actual tax provision (benefit) as follows:

The Company recognized approximately $50,000 in state tax expense for the year ended December 31, 2024.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. As of December 31, 2024, and 2023, there wereno unrecognized tax benefits. The Company recognizes accrued interest and penalties as income tax expense. No amounts were accrued for the payment of interest and penalties at December 31, 2024 and 2023. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position in the next year.
