**MINK THERAPEUTICS, INC. AND SUBSIDIARIES** 

**NOTES TO UNAUDITED INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS** 

**(Unaudited)** 

**(1) Business and Liquidity**

MiNK Therapeutics, Inc. ("MiNK" or the "Company") is a clinical-stage biopharmaceutical company pioneering the discovery, development and manufacturing of allogeneic, off-the-shelf, invariant natural killer T ("iNKT") cell therapies to treat cancer and other immune-mediated diseases. iNKT cells are a distinct T cell population that combine durable memory responses with the rapid cytolytic features of natural killer cells. iNKT cells offer distinct therapeutic advantages as a platform for allogeneic therapy in that the cells naturally home to tissues, aid clearance of tumors and infected cells, and suppress graft-versus-host-disease. MiNK's proprietary platform is designed to facilitate scalable and reproducible manufacturing for off-the-shelf delivery. As such, the Company believes that its approach represents a highly versatile application for therapeutic development in cancer and immune diseases. MiNK is leveraging its platform and manufacturing capabilities to develop a wholly owned or exclusively licensed pipeline of both native and engineered iNKT cells.

Since its inception in 2017, MiNK has incurred losses and expects to continue incurring operating losses and negative cash flows in the future until it is able to generate sales and profits. As of June 30, 2025, MiNK had an accumulated deficit of $151.2 million and cash and cash equivalents of $1.7 million. Subsequent to the quarter end, MiNK received $13.0 million from the sales of common stock in at the market offerings. MiNK believes that its cash and cash equivalents balance, plus the subsequent cash received and additional anticipated funding, will be sufficient to satisfy its liquidity requirements for more than one year from when these financial statements were issued. Because the completion of anticipated funding is not entirely within the Company's control, the Company is required to disclose that substantial doubt exists about its ability to continue as a going concern for a period of one year after the date of filing of this Quarterly Report on Form 10-Q. The financial statements have been prepared on a basis that assumes MiNK will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

Management continually monitors MiNK's liquidity position and adjusts spending as needed in order to preserve liquidity. To support its liquidity requirements the Company will require additional funding. Potential sources of additional funding for the Company include: (1) seeking strategic partnerships and collaborations, as well as out-licensing opportunities, for the Company's portfolio programs and product candidates, (2) exploring avenues for securing non-dilutive financing, such as grants, collaborations, and providing fee-based services to strengthen the Company's balance sheet, and (3) potential of equity or debt financing options.

MiNK's product candidates are in various stages of development and additional expenditures will be required if the Company starts new trials, encounters delays in its programs, applies for regulatory approvals, continues development of its technologies, expands its operations, and/or brings its product candidates to market. The eventual total cost of each clinical trial is dependent on a number of factors such as trial design, length of the trial, number of clinical sites, and number of patients. The process of obtaining and maintaining regulatory approvals for new therapeutic products is lengthy, expensive, and uncertain. Because all of the Company's programs are at an early stage of clinical development, the Company is unable to reliably estimate the cost of completing its research and development programs or the timing for bringing such programs to various markets or substantial partnering or out-licensing arrangements, and, therefore, when, if ever, material cash inflows are likely to commence.

**(2) Significant Accounting Policies** 

The Company's significant accounting policies are disclosed in the consolidated financial statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024, filed with the Securities and Exchange Commission ("SEC") on March 18, 2025. Since the date of those financial statements there have been no changes to the Company's significant accounting policies.

***Financial Statement Preparation***

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and with the instructions to Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete annual consolidated financial statements. In the opinion of the Company's management, the condensed consolidated financial statements include all normal and recurring adjustments considered necessary for a fair presentation of the Company's financial position and operating results. All significant intercompany transactions and accounts have been eliminated in consolidation. Operating results for the six months ended June 30, 2025, are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.

------

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amount of expenses during the reporting period. Management bases its estimates on historical experience and on various assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from those estimates.

For the Company's foreign subsidiaries, the local currency is the functional currency. Assets and liabilities of its foreign subsidiaries are translated into U.S. dollars using rates in effect at the balance sheet date while expenses are translated into U.S. dollars using average exchange rates during the period. The cumulative translation adjustment resulting from changes in exchange rates are included in the condensed consolidated balance sheets as a component of accumulated other comprehensive income (loss) in total stockholders' deficit.

In the quarter ended June 30, 2024, the Company deconsolidated a foreign subsidiary and recognized a gain of approximately $185,000, included in "Other income (expense), net" on its condensed consolidated statements of operations and comprehensive loss.

On January 17, 2025, MiNK executed a reverse stock split of its issued and outstanding common stock, par value $0.00001, at a ratio of 1-for-10 with a record date of January 28, 2025 (the "Reverse Stock Split"). All common share, per share and related information included in the accompanying financial statements and footnote disclosures have been adjusted retroactively, where applicable, to reflect the Reverse Stock Split. See Note 9 for further details.

**(3) Net Loss Per Share** 

Basic loss per common share is calculated by dividing the net loss by the weighted average number of common shares outstanding. Diluted loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding plus the dilutive effect of outstanding instruments such as stock options. Because the Company reported a net loss for all periods presented, diluted loss per common share is the same as basic loss per common share, as the effect of utilizing the fully diluted share count would have reduced the net loss per common share. Therefore, the following potentially dilutive securities have been excluded from the computation of diluted weighted average shares outstanding as of June 30, 2025 and 2024, as they would be anti-dilutive:

Other current liabilities of $2.4 million as of June 30, 2025 and $2.3 million as of December 31, 2024, represent the advance received under the Company's research and development agreement with the Belgium Walloon Region Government ("Walloon Region"). In 2022, the Company received notice that the Walloon Region had obtained a default judgment seeking repayment of approximately $2.4 million of the advance based upon the Company allegedly not providing required notification that research and operations in the region were discontinued.

**(6) Share-based Compensation Plans** 

The Company primarily uses the Black-Scholes option pricing model to value options granted to employees and non-employees, as well as options granted to members of the Company's Board of Directors. All stock option grants have 10-year terms and generally vest ratably over a 3 or 4-year period.

A summary of option activity for the six-month period ended June 30, 2025 is presented below:

The weighted average grant-date fair values of options granted during the six months ended June 30, 2025 and 2024 were $5.92 and $6.90, respectively.

On June 18, 2025, at the Company's annual meeting of stockholders, the Company's stockholders approved a one-time exchange of options to purchase shares of the Company's common stock issued under the Company's 2021 Equity Incentive Plan (the "2021 Plan") and the 2018 Equity Incentive Plan (the "2018 Plan" and, together with the 2021 Plan, the "Equity Plans") that were held by the Company's executive officers, other employees, consultants, and non-employee directors, for new options to purchase shares of the Company's common stock (the "Option Exchange"). Pursuant to the Option Exchange, eligible options were cancelled in exchange for an equal number of new options to purchase shares of common stock with an exercise price equal to the fair market value of the Company's common stock at the time of the Option Exchange and a term of the option that extends ten years from the date of grant. An eligible stock option generally included any outstanding stock option that had an exercise price equal to or greater than $8.50 per share and greater than the closing price of the Company's common stock on the date of the Option Exchange, that vested based on continued service with the Company or based on the achievement of performance milestones and that was granted under the Equity Plans. The Option Exchange resulted in the re-pricing of 647,915 options to an exercise price of $7.43. The vesting conditions of the modified options remained the same and the modified awards have a 10-year term. Total expected incremental share-based compensation expense resulting from the modification is approximately $0.6 million, of which $0.4 million relates to vested awards and was recognized immediately with $0.2 million being recognized over the remaining vesting period.

As of June 30, 2025, there was $1.4 million of unrecognized share-based compensation expense related to stock options granted to employees, consultants and directors which, if all milestones are achieved on outstanding performance-based awards, will be recognized over a weighted average period of 0.7 years. For awards with performance conditions, expense is recognized if the underlying performance conditions are deemed probable of achievement.

**(7) Related Party Transactions** 

Until the completion of its Initial Public Offering ("IPO"), the Company relied on Agenus for all of its working capital requirements. For the periods presented, certain of the Company's operations were fully integrated with Agenus, including, but not limited to, corporate functions such as finance, human resources, information technology and certain legal functions. The Company's consolidated financial statements reflect all costs of doing business related to these operations.

In September 2021, the Company entered into an Intellectual Property Assignment and License Agreement with Agenus (the "New Assignment and License Agreement"), upon which the prior intercompany agreement between Agenus and MiNK was terminated. Pursuant to the New Assignment and License Agreement, Agenus assigned to the Company certain patent rights and know-how related to its iNKT cell platform, product candidates and other patents and know-how related to its business. In addition to the patent rights assigned to the Company by Agenus, the Company also received an exclusive, royalty-free, sublicensable license to research, develop, manufacture and commercialize certain licensed technology in the field. The New Assignment and License Agreement further provides for the Company to grant Agenus a field-limited, non-exclusive, royalty-free license under the assigned patent rights, subject to MiNK's discretion and provided such access would not reasonably result in a disruption of planned MiNK activities. Agenus has also agreed to provide the Company with Agenus' biological material upon written request in order for the Company to use such material in its development activities of a combination therapy. Agenus may withhold the transfer of biological material, including, but not limited to, checkpoint modulating antibodies, for various reasons, including if such transfer would reasonably result in a disruption of planned Agenus activities. For any materials Agenus does share with the Company, the parties have agreed to enter into a separate agreement governing the transfer and providing for joint ownership of the data. Agenus has agreed that during the full term of the New Assignment and License Agreement, and for three years thereafter, it will not develop, manufacture or commercialize an iNKT cell therapy, directly or indirectly by transferring such technology. The Company may terminate the New Assignment and License Agreement without cause upon 90 days' prior written notice to Agenus. Either party may terminate if there has been a material breach which has not been cured within 90 days (or 45 days for breach of payment obligations) of receiving such notice.

Effective April 1, 2022, the Company entered into an Amended and Restated Intercompany Services Agreement (the "New Intercompany Agreement") with Agenus, which amended and restated the Intercompany General & Administrative Agreement

------

between the Company and Agenus dated September 10, 2021 (the "Prior Intercompany Agreement"). Under the New Intercompany Agreement, Agenus provides the Company with certain general and administrative support, including, without limitation, financial, facilities management, human resources and information technology administrative support (the "Agenus Services"), and the Company and Agenus provide each other with certain research and development services (the "R&D Services") and other support services, including legal and regulatory support (the "Shared Services"). The Company is required to pay 10% of Agenus' costs related to the Agenus Services, and the costs of R&D Services are based upon pass-through costs related to such services plus an allocation of the costs of the employees performing the services. No payment will be due from either party for the Shared Services, provided that the services provided by each party are proportional in scope and volume. The Company is also entitled to use Agenus' business offices and laboratory space and equipment in exchange for the Company contributing a proportionate payment for the use of such facilities and equipment, and the Company will be covered by certain Agenus insurance policies, subject to certain conditions, including the Company paying the cost of such coverage. Either party may terminate the New Intercompany Agreement upon 60 days' prior written notice and individual services upon 30 days' prior written notice.

Allocated Agenus services primarily include payroll related expenses, facility costs, insurance and stock-based compensation, and are included in the accompanying financial statements based on certain estimates and allocations described above. Under the Prior Intercompany Agreement, the allocation methods primarily included time devoted to activities and headcount-based allocations. Agenus business services and occupancy costs were allocated to the Company based on the Company's headcount as a percentage of Agenus' and the Company was required to pay 105% of Agenus' costs for these business services and occupancy costs. Research services were charged between the entities based on hours recorded by Agenus employees as time spent on specific projects, applied to hourly wage rates, and the Company paid 110% of Agenus' costs for these research services. As such, these allocations may not be indicative of the actual amounts that would have been recorded had the Company operated as an independent, publicly traded company for the periods presented.

Allocation of Agenus services, net of approximately $252,000 and $216,000 for the three months ended June 30, 2025 and 2024, respectively, and $487,000 and $443,000 for the six months ended June 30, 2025 and 2024, respectively, is included in "Operating expenses" in the Company's statement of operations and "Due to related parties," of $14.5 million as of June 30, 2025, in the Company's condensed consolidated balance sheet. Agenus has agreed to not require repayment of this balance for the foreseeable future.

On February 12, 2024, the Company and Agenus entered into a Convertible Promissory Note Purchase Agreement (the "Purchase Agreement") pursuant to which the Company issued to Agenus a convertible promissory note in the principal amount of up to $5.0 million (the "Note"). The Purchase Agreement sets forth the terms and conditions, including representations and warranties, for the Company's issuance and sale of the Note to Agenus.

The Note carries an annual rate of interest rate of 2% (the "Interest Rate") that accrues from the date funds are paid or advanced by Agenus to the Company. Interest shall accrue and not be payable until converted or paid in connection with the repayment in full of the principal amount of the Note. The Note provides that the Company will pay Agenus on request the principal amount outstanding, together with any unpaid interest, on or after January 1, 2026. In the event of a qualified financing event, as defined in the Note, the outstanding principal amount of the Note plus accrued and unpaid interest shall, at Agenus' election, either be paid in full or converted into equity shares equal to the quotient obtained by dividing (i) the amount due on the date of conversion by (ii) 80% of the per share price of the equity securities sold in the qualified financing. Upon a change of control, the Company will pay Agenus an amount equal to (i) 1.5 times the principal then outstanding under the Note and (ii) the amount of accrued interest then outstanding immediately prior to the closing of such change of control.

In March 2024, MiNK received $5.0 million from Agenus and the Note was fully drawn. As of June 30, 2025, the Note had a principal balance of $5.0 million, an accrued and unpaid interest balance of approximately $129,000 and a market interest rate of 15.0%.

In January 2023, the Company's Chief Executive Officer ("CEO" or "Dr. Buell"), became an employee of Agenus in the role of Chairman of the Executive Council, and she was appointed to the Agenus Board of Directors in June 2024. As an employee of Agenus, Dr. Buell is paid $150,000 annually. In June 2024 Dr. Buell was granted an option to acquire 37,500 shares of Agenus common stock that vest over a period of three years, in November 2024 she was granted an option to acquire 300,000 shares of Agenus common stock that vest after one year and in June 2025 Dr. Buell was granted an option to acquire 6,750 shares of Agenus common stock that vest over a period of three years. Dr. Buell receives no additional compensation as an Agenus board member.

Dr. Buell's spouse is a partner in the law firm of Wolf, Greenfield & Sachs, P.C. ("Wolf Greenfield"), which provided legal services to the Company during the periods ended June 30, 2025 and 2024, and continues to do so. For the three and six months ended June 30, 2025, the Company expensed Wolf Greenfield fees totaling approximately $61,800 and $152,400, respectively, and for the three and six months ended June 30, 2024, the Company expensed Wolf Greenfield fees totaling approximately $51,200 and $78,700,

------

respectively. Dr. Buell's spouse does not receive direct compensation from the fees paid to Wolf Greenfield by the Company and the fees paid by the Company to Wolf Greenfield in the period were an insignificant amount of Wolf Greenfield's revenues. The Company's Audit and Finance Committee approved these services under its related-party transactions policy.

**(8) Fair Value Measurement** 

The Company measures the Note at fair value. The fair value of the Note at June 30, 2025 was approximately $5.4 million, using a scenario based present value methodology that was derived by evaluating the nature and terms of the Note and considering the prevailing economic and market conditions at the balance sheet date, some of which are considered Level 2 inputs under the fair value measurements standard. As of June 30, 2025 the Note had a principal balance of $5.0 million. The initial difference between the determined fair value at the issuance of the Note and the proceeds received was recorded as additional paid-in capital at the date of issuance. The difference between the fair value of the Note at December 31, 2024 and the fair value of the Note as of June 30, 2025 was recorded in "Operating expenses" in the Company's condensed consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2025.

**(9) Equity** 

On January 17, 2025, the Company's stockholders approved a proposal to amend its Amended and Restated Certificate of Incorporation, as amended (the "Certificate of Incorporation"), to effect the Reverse Stock Split at a ratio of 1-for-10. On January 17, 2025, the Company filed a Certificate of Amendment (the "Certificate of Amendment") to its Certificate of Incorporation with the Secretary of State of the State of Delaware to effect the Reverse Stock Split. Pursuant to the Certificate of Amendment, the Reverse Stock Split became effective at 12:01 a.m., Eastern Time, on January 28, 2025. As of the opening of trading on January 28, 2025, MiNK's common stock began trading on a post-split basis under CUSIP number 603693 201.

All common share, per share and related information included in the accompanying financial statements and footnote disclosures have been adjusted retroactively, where applicable, to reflect the Reverse Stock Split.

On May 13, 2025, MiNK received a letter (the "MVLS Notice") from the Listing Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq") notifying it that for the previous 30 consecutive trading days the Company's Minimum Value of Listed Securities ("MVLS") was less than $35.0 million, as required by Nasdaq Listing Rule 5550(b)(2) (the "MVLS Rule"). Nasdaq has provided the Company with 180 calendar days, or until November 10, 2025, to regain compliance. To regain compliance, the Company's MVLS had to have met or exceeded $35.0 million for a minimum of ten consecutive trading days.

On July 28, 2025, the Company was notified by the Nasdaq Listing Qualifications Department staff that the Company's MVLS met or exceeded $35.0 million for at least ten consecutive business days. Accordingly, the Company regained compliance with the MVLS Rule and this matter is now closed.

**(10) Segments** 

MiNK is managed and operated as one business segment. The Company does not operate separate lines of business with respect to any of its product candidates or geographic locations. MiNK's single reportable segment is focused on the discovery, development and manufacturing of allogeneic, off-the-shelf, iNKT cell therapies to treat cancer and other immune-mediated diseases.

MiNK's CEO serves as its Chief Operating Decision Maker ("CODM") and is responsible for reviewing company performance and making decisions regarding resource allocation. The Company's CODM evaluates company performance based on net loss, as included in the Consolidated Statements of Operations and Comprehensive Loss, ensuring resource allocation decisions support company goals. The measure of segment assets is total assets, as included in the Consolidated Balance Sheets. Refer to the consolidated financial statements for other financial information regarding the Company's single reportable segment.

In the table above, "Other operating expenses" includes items such as the allocation of Agenus Services, depreciation and amortization expense, stock-based compensation expense, fair value adjustments and expenses related to certain foreign subsidiaries.

**(11) Contingencies** 

The Company may currently be, or may become, a party to legal proceedings. While the Company currently believes that the ultimate outcome of any of these proceedings will not have a material adverse effect on its financial position, results of operations, or liquidity, litigation is subject to inherent uncertainty and consumes both cash and management attention.

**(12)** Recent Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 requires incremental annual disclosures around income tax rate reconciliations, income taxes paid and other related disclosures. For the Company, ASU 2023-09 is effective for fiscal years beginning after December 15, 2025. Early adoption is permitted for any annual periods for which financial statements have not been issued or made available for issuance. The Company is currently evaluating the impact that ASU 2023-09 will have on the notes to its consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (DISE). This new guidance requires all public entities to incorporate disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. Public entities must adopt ASU 2024-03 prospectively for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption and retrospective application are permitted. The Company is currently evaluating the impact that ASU 2024-03 will have on its consolidated financial statements.

No other new accounting pronouncement issued or effective during the six months ended June 30, 2025 had or is expected to have a material impact on the Company's consolidated financial statements or disclosures.

**(13) Subsequent Events** 

*At the Market Sales Agreement*

On July 15, 2025, the Company entered into an At Market Issuance Sales Agreement (the "Sales Agreement") with B. Riley Securities, Inc., as sales agent (the "Sales Agent") to sell shares of the Company's common stock, from time to time through the Sales Agent, at a maximum aggregate offering price of $50.0 million. The issuances and sales under the Sales Agreement are pursuant to the Company's registration statement on Form S-3 (File No. 333-268143) (the "Registration Statement") filed with the Securities and Exchange Commission on November 3, 2022, the base prospectus included in the Registration Statement, dated November 8, 2022, and a prospectus supplement, dated July 15, 2025.

In July 2025, the Company sold approximately 478,000 shares of its common stock under the Sales Agreement, resulting in net proceeds of approximately $13.0 million.

*Controlled Company Status*

------

As a result of the shares issued and sold under the Sales Agreement in July 2025, the Company's largest stockholder, Agenus, which previously owned more than 50% of the voting power of the Company's common stock, owned less than 50% of the voting power of the Company's common stock as of July 2025. As a result, the Company no longer qualifies as a "Controlled Company" as defined in Nasdaq Rule 5615(a)(7).

*Nasdaq Compliance*

On July 28, 2025, the Company received a letter from Nasdaq notifying the Company it had regained compliance with the MVLS Rule and that it complied with the requirements for continued listing.

**Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.**

**Overview** 

MiNK Therapeutics, Inc. ("we," "us," "our," or "Company") is a clinical-stage biopharmaceutical company pioneering the discovery, development and manufacturing of allogeneic, off-the-shelf invariant natural killer T ("iNKT") cell therapies to treat cancer and other immune-mediated diseases. iNKT cells are a distinct T cell population that combine durable memory responses with the rapid cytolytic features of natural killer ("NK") cells. iNKT cells offer distinct therapeutic advantages as a platform for allogeneic therapy in that the cells naturally home to tissues, aid clearance of tumors and infected cells and suppress Graft versus Host Disease ("GvHD"). Our proprietary platform is designed to facilitate scalable and reproducible manufacturing for off-the-shelf delivery. As such, we believe that our approach represents a highly versatile application for therapeutic development in cancer and immune diseases. We are leveraging our platform and manufacturing capabilities to develop a wholly owned or exclusively licensed pipeline of both native and engineered iNKT cells.

Our business activities include product research and development, manufacturing, regulatory and clinical development, corporate finance, and support of our collaborations. To be successful, our product candidates require clinical trials and approvals from regulatory agencies, as well as acceptance in the marketplace. We are a party to an Amended and Restated Intercompany Services Agreement (the "New Intercompany Agreement") and an Intellectual Property Assignment and License Agreement with Agenus Inc. ("Agenus"). Under the New Intercompany Agreement, Agenus provides us with certain general and administrative support, including, without limitation, financial, facilities management, human resources and information technology administrative support, and we and Agenus provide each other with certain research and development services and other support services, including legal and regulatory support. We are also entitled to use Agenus' business offices and laboratory space and equipment in exchange for us contributing a proportionate payment for the use of such facilities and equipment, and we will be covered by certain Agenus insurance policies, subject to certain conditions, including us paying the cost of such coverage. Under the Intellectual Property Assignment and License Agreement, Agenus exclusively assigned patent rights and know-how related to our technology to us. We also have a field-limited exclusive license under certain Agenus patents and know-how; and we retain the rights to expand a proprietary pipeline of products and technologies.

Our most advanced product candidate, agenT-797, is an off-the-shelf, allogeneic, native iNKT cell therapy. iNKTs are a potent class of immune cells and serve as master regulators of immune response, possessing the killing power of NK cells and the memory of T-cells. Our proprietary manufacturing platform enables the infusion of these cells in billion-fold quantities, equipping the immune system to combat cancer and other life-threatening diseases. We have successfully established and launched in-house iNKT cell manufacturing and product release capacity, capable of supplying over 5,000 doses annually through a U.S. Food and Drug Administration ("FDA")-cleared, scalable, fully closed, and automated process.

Our clinical development of agenT-797 is advancing in multiple therapeutic areas of significant unmet needs. These include a Phase 2 trial in 2L gastric cancer and viral acute respiratory distress syndrome ("ARDS") in populations of patients where there are critical gaps in current treatment options.

In solid tumors, we have completed a Phase 1 trial of agenT-797 in both monotherapy and combination settings with anti-PD-1 checkpoint inhibitors pembrolizumab and nivolumab. The trial demonstrated durable clinical benefit with a favorable safety profile across heavily pre-treated cancers, including non-small cell lung cancer ("NSCLC"), testicular cancer, and gastric cancer. Median progression-free survival exceeded six months, and approximately 30% of patients achieved durable disease stabilization, including in cancers refractory to prior anti-PD-1 therapy.

Nature Oncogene highlights two landmark cases from this program, the most recent of which was published in July 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•A patient with refractory metastatic testicular cancer who achieved a durable complete remission following a single infusion of agenT-797 in combination with checkpoint blockade after failing multiple lines of therapy, including platinum chemotherapy and immune checkpoint inhibitors. The patient remains disease-free more than two years post-treatment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•A patient with advanced gastric cancer who achieved a durable partial response with agenT-797 plus checkpoint blockade, with meaningful tumor reduction and sustained disease control despite prior progression on standard therapies.

Building on these results, a randomized, Phase 2 investigator-sponsored trial led by Dr. Yelena Janjigian at Memorial Sloan Kettering Cancer Center is actively enrolling patients with previously treated, advanced esophageal, gastric, or gastroesophageal junction adenocarcinoma. This study is evaluating a combination regimen of agenT-797, botensilimab (a novel Fc-enhanced CTLA-4 inhibitor), balstilimab (anti-PD-1), ramucirumab, and paclitaxel. The trial, expected to enroll approximately 38 patients with advanced, unresectable, or metastatic disease, is a strategic priority for the Company. The inclusion of agenT-797 in this regimen reflects growing clinical interest following the durable responses observed in Phase 1, including the Nature Oncogene complete and partial responder cases, and aims to determine whether similar benefits can be achieved in 2L gastric cancer.

agenT-797 in both monotherapy and combination settings has been presented at major scientific meetings, including American Association for Cancer Research ("AACR") and Society for Immunotherapy of Cancer ("SITC") conferences.

In inflammatory diseases, we have completed a phase 1 study of agenT-797 in viral ARDS, leveraging the unique anti-inflammatory properties of iNKT cells. Results from our Phase 1 study were published in Nature Communications and presented at the American Thoracic Society International Conference over the past two years. We reported an encouraging survival benefit of 75%, compared to approximately 10-22% in an in-hospital control group and time-matched data from the Centers for Disease Control and Prevention. In a cohort of 21 patients on mechanical ventilation, survival rates exceeded 70%, with an 80% survival rate among those on venovenous extracorporeal membrane oxygenation. In addition to a survival benefit, agenT-797 improved lung function and significantly reduced inflammation and secondary infections, which are major contributors to comorbidity and mortality in intensive care units. Given the lack of approved therapies for ARDS, we plan to advance agenT-797 in viral ARDS through strategic collaborations and non-dilutive external financing into a randomized Phase 2 trial.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our pipeline is advancing next-generation allogeneic, engineered iNKT programs. Our two most advanced engineered programs are (1) MiNK-215, an IL-15 armored tumor stromal targeting FAP-CAR-iNKT and (2) MiNK-413, an IL-15 armored CAR-iNKT program targeting BCMA program. MiNK-413 has demonstrated tumor clearance and improved persistence in preclinical models, as well as manufacturing and logistical improvements over current BCMA cell therapies. MiNK-215 has demonstrated efficacy in NSCLC and melanoma preclinical models, promoting curative responses, eliminating tumor burden in the lungs, and enhancing tumor specific CD8+ T cell infiltration through tumor stroma. These data and programs were presented at AACR in 2024, International Cancer Immunotherapy Conference in 2023, SITC in 2023, and the American Society of Cell and Gene Therapy in 2023. Most recently, preclinical data from MiNK-215 in microsatellite stability colorectal cancer liver metastases were presented at AACR 2024. This presentation highlighted MiNK-215's potent anti-tumor activity, immune activation, and tumor stroma remodeling against this difficult-to-treat solid tumor setting. Investigational new drug ("IND") enabling activities are underway we expect to submit an IND to the FDA in 2025.

In December 2023, we announced a collaboration with ImmunoScape, Inc. ("ImmunoScape") to discover and develop next-generation T-cell receptor therapies against novel targets in solid tumors. We will combine our unique, proprietary library of T cell antigens with ImmunoScape's platform for rapid discovery of novel T cell receptors. ImmunoScape's unique Deep Immunomics platform enables high-throughput and sensitive screening of T cells against relevant tumor targets for the rapid discovery of rare, therapeutically-relevant T-cell receptors ("TCRs"). We have a proprietary library of phospho-peptide neoantigens derived from a wide range of solid tumors and hematologic malignancies. In this collaborative effort, ImmunoScape will leverage its capabilities in multiplex antigen screening and in-depth T cell profiling to identify relevant TCRs targeting the library of phospho-peptide antigens. We will further characterize these tumor-specific TCRs, leveraging our proprietary capabilities to analyze and select TCR candidates for optimal tumor targeting. Any intellectual property resulting from the arrangement would be jointly owned by the parties.

**Historical Results of Operations** 

***Three Months Ended June 30, 2025 Compared to the Three Months Ended June 30, 2024*** 

*Research and development expense* 

Research and development ("R&D") expense includes the costs associated with our internal research and development activities, including compensation and benefits, occupancy costs, manufacturing costs, costs of expert consultants, and administrative costs. R&D expense was $1.8 million for both the three months ended June 30, 2025 and 2024.

*General and administrative expense* 

General and administrative ("G&A") expense consists primarily of personnel costs, facility expenses, and professional fees. G&A expense increased 74% to $1.8 million for the three months ended June 30, 2025 from $1.1 million for the three months ended June 30, 2024. This increase is primarily due to an increase in professional fees and the incremental share-based compensation expense resulting from the option award modification approved by shareholders in June 2025.

*Other income (expense), net*

Other expense increased to approximately $186,000 for the three months ended June 30, 2025 from income of approximately $331,000 for the three months ended June 30, 2024, primarily due to foreign currency exchange losses in the three months ended June 30, 2025, compared to the $185,000 gain recognized on the deconsolidation of a foreign subsidiary and the recognition of a refundable R&D tax credit in the UK in the three months ended June 30, 2024.

*Interest income, net* 

Interest income decreased $38,000 for the three months ended June 30, 2025, from income of $38,400 for the three months ended June 30, 2024 to income of $300 for the three months ended June 30, 2025, primarily due to interest expense accrued under our related party note (the "Note") and decreased interest earned on our money market funds.

***Six Months Ended June 30, 2025 Compared to the Six Months Ended June 30, 2024***

*Research and development expense*

R&D expense includes the costs associated with our internal research and development activities, including compensation and benefits, occupancy costs, manufacturing costs, costs of expert consultants, and administrative costs. R&D expense decreased 29% to $3.1 million for the six months ended June 30, 2025 from $4.4 million for the six months ended June 30, 2024. This decrease is primarily due to decreased costs associated with both the timing of our clinical trials and pre-clinical activities as well as decreased personnel costs, primarily due to decreased headcount.

*General and administrative expense*

G&A expense consists primarily of personnel costs, facility expenses, and professional fees. G&A expense increased 33% to $3.1 million for the six months ended June 30, 2025 from $2.3 million for the six months ended June 30, 2024. This increase is primarily due to an increase in professional fees and the incremental share-based compensation expense resulting from the option award modification approved by shareholders in June 2025.

*Other income, net*

Other expense increased to approximately $265,000 for the six months ended June 30, 2025 from income of approximately $331,000 for the six months ended June 30, 2024, primarily due to foreign currency exchange losses in the six months ended June 30, 2025, compared to the $185,000 gain recognized on the deconsolidation of a foreign subsidiary and the recognition of a refundable R&D tax credit in the UK in the six months ended June 30, 2024.

*Interest income, net*

Interest income decreased $41,000 for the six months ended June 30, 2025, from income of $55,000 for the six months ended June 30, 2024 to income of $14,000 for the six months ended June 30, 2025, primarily due to decreased interest earned on our money market funds and interest expense accrued under the Note.

Our product candidates are in various stages of development and significant additional expenditures will be required if we start new clinical trials, encounter delays in our programs, apply for regulatory approvals, continue development of our technologies, expand our operations and/or bring our product candidates to market. The total cost of any particular clinical trial is dependent on a number of factors such as trial design, length of the trial, number of clinical sites, number of patients and trial sponsorship. The process of obtaining and maintaining regulatory approvals for new products is lengthy, expensive and uncertain. Because of the current stage of our product candidates, among other factors, we are unable to reliably estimate the cost of completing our research and development programs or the timing for bringing such programs to various markets or substantial partnering or out-licensing arrangements, and, therefore, when, if ever, material cash inflows are likely to commence.

**Liquidity and Capital Resources** 

We have incurred annual operating losses since inception in 2017, and we had an accumulated deficit of $151.2 million as of June 30, 2025. We expect to incur losses over the next several years as we continue development of our technologies and product candidates, manage our regulatory processes, initiate and continue clinical trials, and prepare for potential commercialization of products.

On July 15, 2025, we entered into an At Market Issuance Sales Agreement (the "Sales Agreement") with B. Riley Securities, Inc., as sales agent (the "Sales Agent") to sell shares of our common stock, from time to time through the Sales Agent, at a maximum aggregate offering price of $50.0 million. The issuances and sales under the Sales Agreement are pursuant to our registration statement on Form S-3 (File No. 333-268143) (the "Registration Statement") filed with the Securities and Exchange Commission on November 3, 2022, the base prospectus included in the Registration Statement, dated November 8, 2022, and a prospectus supplement, dated July 15, 2025. In July 2025, we sold approximately 478,000 shares of our common stock under the Sales Agreement, resulting in net proceeds of approximately $13.0 million.

We have a Note outstanding as of June 30, 2025 of $5.0 million in principal plus accrued and unpaid interest of approximately $129,000. The Note provides that we will pay Agenus on request the principal amount outstanding, together with any unpaid interest, on or after January 1, 2026. In the event of a qualified financing event, as described in the Note, at Agenus' election, we must pay the principal amount outstanding and any unpaid interest, either in full or in the form of equity securities.

In May 2024, we entered into a stock purchase agreement with an investor, pursuant to which we issued and sold an aggregate of 464,000 shares of common stock, at a purchase price of $12.50 per share, for an aggregate purchase price of approximately $5.8 million.

Our cash and cash equivalents balance as of June 30, 2025 was $1.7 million. Subsequent to the quarter end, we received $13.0 million from the sales of common stock in at the market offerings. We believe our cash and cash equivalents balance, plus the subsequent cash received and additional anticipated funding, will be sufficient to satisfy our liquidity requirements for more than one year from when these financial statements were issued. Because the completion of anticipated funding is not entirely within our control, we are required to disclose that substantial doubt exists about our ability to continue as a going concern for a period of one year after the date of filing of this Quarterly Report on Form 10-Q. The financial statements have been prepared on a basis that assumes we will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

Management continually monitors the Company's liquidity position and adjusts spending as needed in order to preserve liquidity. To support our liquidity requirements we will require additional funding. Potential sources of additional funding include: (1) seeking strategic partnerships and collaborations, as well as out-licensing opportunities, for our portfolio programs and product

------

candidates, (2) exploring avenues for securing non-dilutive financing, such as grants, collaborations, and providing fee-based services to strengthen our balance sheet, and (3) potential of equity or debt financing options.

Net cash used in operating activities for the six months ended June 30, 2025 and 2024 was $2.9 million and $4.8 million, respectively. Our future ability to generate cash from operations will depend on achieving regulatory approval and market acceptance of our product candidates, and our ability to enter into collaborations.

**Forward-Looking Statements**

This Quarterly Report on Form 10-Q and other written and oral statements we make from time to time contain certain "forward-looking" statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 (the "Exchange Act"). You can identify these forward-looking statements by the fact they use words such as "could," "expect," "anticipate," "estimate," "target," "may," "project," "guidance," "intend," "plan," "believe," "will," "potential," "opportunity," and "future," and other words and terms of similar meaning and expression in connection with any discussion of future operating or financial performance. You can also identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. Such forward-looking statements are based on current expectations and involve inherent risks and uncertainties, and other important factors, including factors that could delay, divert or change any of them, and could cause actual outcomes to differ materially from current expectations. These statements relate to, among other things, our business strategy, our research and development, our product development efforts, our ability to develop, including our ability to develop and obtain licensure of agenT-797, MiNK-215, and MiNK-413, our prospects for initiating partnerships or collaborations, the timing of the introduction of products, the effect of new accounting pronouncements, uncertainty regarding our future operating results and our profitability, our cash runway and anticipated sources of funds as well as our plans, objectives, expectations, and intentions.

More detailed descriptions of these risks and uncertainties and other risks and uncertainties applicable to our business that we believe could cause actual results to differ materially from any forward-looking statements are included in in Part I-Item 1A "Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 as updated by Part II-Item 1A "Risk Factors" elsewhere in this Quarterly Report on Form 10-Q. We encourage you to read those descriptions carefully. Although we believe we have been prudent in our plans and assumptions, no assurance can be given that any goal or plan set forth in forward-looking statements can be achieved. We caution investors not to place significant reliance on forward-looking statements contained in this document; such statements need to be evaluated in light of all the information contained in this document. Furthermore, the statements speak only as of the date of this document, and we undertake no obligation to update or revise these statements.

**JOBS Act** 

We qualify as an "emerging growth company" as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). As an emerging growth company, we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies, including reduced disclosure about our executive compensation arrangements, exemption from the requirements to hold non-binding advisory votes on executive compensation and golden parachute payments and exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting.

We may take advantage of these exemptions until the last day of the fiscal year following the fifth anniversary of our initial public offering or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company earlier if (i) we have more than $1.235 billion in annual revenue, (ii) we are deemed to be a large accelerated filer, which among other things would require us to have more than $700.0 million in market value of our stock held by non-affiliates as of the last business day of our prior second fiscal quarter, or (iii) we issue more than $1.0 billion of non-convertible debt securities over a three-year period. For so long as we remain an emerging growth company, we are permitted, and intend, to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. We may choose to take advantage of some, but not all, of the available exemptions.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected not to "opt out" of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we will adopt the new or revised standard at the time private companies adopt the new or revised standard and will do so until such time that we either (i) irrevocably elect to "opt out" of such extended transition period or (ii) no longer qualify as an emerging growth company. Therefore, the reported results of operations contained in our consolidated financial statements may not be directly comparable to those of other public companies.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk.**

This item is not required for smaller reporting companies.

**Item 4. Controls and Procedures.**

**Evaluation of Disclosure Controls and Procedures**

Under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) and Rule 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Based on this evaluation, our Principal Executive Officer and our Principal Financial Officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective and were designed to ensure that information we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Principal Executive Officer and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure, and is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. It should be noted that any system of controls is designed to provide reasonable, but not absolute, assurances that the system will achieve its stated goals under all reasonably foreseeable circumstances. Our Principal Executive Officer and Principal Financial Officer have each concluded that our disclosure controls and procedures as of the end of the period covered by this report are effective at a level that provides such reasonable assurances.

**Changes in Internal Control Over Financial Reporting**

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the three months ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

------

**PART II—OTHER INFORMATION**

**Item 1. Legal Proceedings.**

We are not a party to any material legal proceedings.

**Item 1A. Risk Factors.**

Our results of operations and financial condition are subject to numerous risks and uncertainties described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. Other than as described below, there have been no material changes to the risk factors described in Part I, Item 1A "Risk Factors" of our 2024 Form 10-K.

**Risks Related to Our Relationship with Agenus** 

*Agenus owns a significant portion our common stock and may be able to exert control over specific matters subject to stockholder approval.* 

Agenus beneficially owns approximately 48% of our outstanding common stock. Therefore, Agenus may have the ability to substantially influence us through this ownership position. For example, Agenus may be able to control or influence elections of directors, amendments of our organizational documents or approval of any merger, sale of assets or other major corporate transaction. Agenus' interests may not always coincide with our corporate interests or the interests of other stockholders, and they may act in a manner with which you may not agree or that may not be in the best interests of us or our other stockholders. So long as Agenus continues to own a significant amount of our equity, it may be able to continue to be able to strongly influence or effectively control our decisions. Agenus could remain a significant stockholder for an extended period of time or indefinitely. Even though Agenus controls less than a majority of the voting power of our outstanding common stock, it may be able to influence the outcome of our corporate actions so long as it owns a significant portion of our common stock.

*The loss of controlled company status could disrupt our business.* 

Until recently, Agenus controlled a majority of the voting power of our outstanding common stock. As a result, we were a "controlled company" within the meaning of the Nasdaq corporate governance requirements. Under these rules, a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company is a "controlled company" and may elect not to comply with certain corporate governance requirements. Nasdaq rules require that, within one year of the date we no longer qualified as a "controlled company," among other things, we have a majority of independent directors on our board of directors, a compensation committee consisting solely of independent directors, and a director nominations process whereby directors are selected by a nominations committee consisting solely of independent directors or by a vote of the board of directors in which only independent directors participate. During this transition period, we may continue to utilize the available exemptions from certain Nasdaq corporate governance requirements, and accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the Nasdaq corporate governance requirements. This could make our common stock less attractive to some investors or otherwise adversely affect its trading price.

There may be other effects of the loss of controlled company status on the trading price of our common stock and on our business, including our ability to retain and hire key personnel and maintain relationships with Agenus, our customers, and our suppliers. In addition, our business may be more likely to be disrupted by persons seeking to influence or effect a change of control, change of management or change in governance of our company. Any such disruptions to our business could have a material adverse effect on our operations and financial results.

*If Agenus sells a significant interest in our company to a third party in a private transaction that results in that third party owning a controlling interest in the company, you may not realize a change of control premium on shares of our common stock, and we would become subject to the control of a presently unknown third party. In addition, Agenus may distribute a portion of the shares of our common stock it currently holds to its stockholders, which could impact our share price or volatility.* 

Agenus owns a significant equity interest in our company. This means that Agenus could choose to sell some or all of its shares of our common stock in a privately negotiated transaction, which, if sufficient in size, could result in a change of control of our company.

Agenus' ability to sell its shares of our common stock privately, with no requirement for a concurrent offer to be made to acquire your shares of our common stock, could, even if it results in that third party owning a controlling interest in us, prevent you from realizing any change of control premium on your shares of our common stock that may otherwise accrue to Agenus on its private sale of our common stock. Additionally, if Agenus privately sells its significant equity interest in our company, we may become subject to the control of a presently unknown third party. Such third party may have conflicts of interest with those of other stockholders. In addition, if Agenus sells a portion or all of their significant interest in our company to a third party, such a sale could

------

negatively impact or accelerate any future indebtedness we may incur, and negatively impact any other commercial agreements and relationships, all of which may adversely affect our ability to run our business as described herein and may have a material adverse effect on our operating results and financial condition. Furthermore, Agenus may elect to distribute to its stockholders a portion of the shares of our common stock that it holds. Such Agenus stockholders may then sell the shares of our common stock into the public market. Such sales may not be subject to the volume, manner of sale, holding period and other limitations of Rule 144 and, therefore, may adversely impact our stock price or volatility.

**Item 5. Other Information.**

*Trading Plans of Our Directors and Officers*

During the quarter ended June 30, 2025, none of our directors or executive officers adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each item is defined in Item 408 of Regulation S-K.
