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

Overview

MiNK Therapeutics, Inc. (“we,” “us” and “our”) is a clinical stage biopharmaceutical company pioneering the discovery, development, and commercialization 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 Intercompany General & Administrative Services Agreement and an Intellectual Property Assignment and License Agreement with Agenus. Under the Intercompany General & Administrative Services Agreement, Agenus provides us with administrative support, including, without limitation, financial, legal, information technology and human resources administrative support. Additional non-administrative services and use of certain facilities are available as may be agreed to between the parties from time to time. 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, AGENT-797, is an off-the-shelf, allogeneic, native iNKT cell therapy. We have commenced a Phase 1 clinical trial of AGENT-797 for the treatment of multiple myeloma, reported preliminary signals of activity, and expect to report data from this trial in the fourth quarter of 2022. In addition, we announced the initiation of our Phase 1 clinical trial for the study of solid tumor cancers with AGENT-797 as a monotherapy and in combination with checkpoint inhibitors, which we intend to advance as a priority. We currently expect to have preliminary readouts from this clinical trial in 2022 in indications that may lead to an accelerated path to marketing approval. We also intend to initiate a Phase 1 study of AGENT-797 in GvHD in 2022 and expect to report top-line data from this trial in the second half of 2022. Finally, with the unique circumstances of the COVID-19 pandemic, we were able to commence first-in-human studies of AGENT-797 in acute respiratory distress (“ARDS”) secondary to COVID-19 and reported encouraging survival benefit exceeding 75% presented at the Society of Immunotherapy for Cancer in 2021. Later this year, we expect to present updated data of the clinical effect of AGENT-797 on viral ARDS where there are currently no effective therapies.

In addition, we are advancing a pipeline of next-generation allogeneic, engineered iNKT programs. Our two most advanced engineered programs are (1) a CAR-iNKT program targeting B-cell maturation antigen (“BCMA”), which we refer to as BCMA-CAR-iNKT, and (2) a tumor stromal targeting CAR-iNKT program, which we refer to as stromal target-CAR-iNKT. These programs are both in preclinical development and we expect to initiate our investigational new drug application filings for these candidates in 2022.

Our research and development expenses for the three months ended March 31, 2022 and 2021 were $5.3 million and $3.1 million, respectively. We have incurred losses since our inception. As of March 31, 2022, we had an accumulated deficit of $90.7 million.

Until the completion of our initial public offering, we were reliant on Agenus to finance our operations. We expect to continue to incur operating losses and negative cash flows for the foreseeable future. Based on our current plans and projections, we believe our quarter-end cash and cash equivalents balance will be sufficient to satisfy our liquidity requirements for more than one year from when these financial statements were issued. Management continues to address our liquidity position and will adjust spending as needed in order to preserve liquidity. Our future liquidity needs will be determined primarily by the success of our operations with respect to the progress of our product candidates and key development and regulatory events in the future. Potential sources of additional funding include: (1) pursuing collaboration, out-licensing and/or partnering opportunities for our portfolio programs and product candidates with one or more third parties, (2) securing debt financing and/or (3) selling equity securities.

Historical Results of Operations

Three Months Ended March 31, 2022 Compared to the Three Months Ended March 31, 2021

Research and development expense

Research and development (“R&D”) expense includes compensation and other direct costs plus an allocation of indirect costs, based on certain assumptions. R&D expense increased 70% to $5.3 million for the three months ended March 31, 2022 from $3.1 million for the three months ended March 31, 2021. This increase is primarily due to costs associated with an increase in preclinical activities, the continued advancement of our clinical trials and increased personnel costs.

General and administrative expense

General and administrative (“G&A”) expense consists primarily of personnel costs, facility expenses, and professional fees. G&A expense increased 252% to $2.1 million for the three months ended March 31, 2022 from $0.6 million for the three months ended March 31, 2021. This increase is primarily due to increased personnel costs, including stock-based compensation expense, and increased professional fees, primarily attributable to additional legal, strategy and audit and tax fees.

Change in fair value of convertible affiliated note

Change in fair value of convertible affiliated note reflects the result of our fair value measurement of our convertible affiliated note issued to Agenus (the “Note”) at the balance sheet date. In October 2021, in connection with our initial public offering, the Note was automatically converted into 5,451,958 shares of our common stock and was not outstanding as of March 31, 2022.

Interest expense

Interest expense related to the Note was $0.7 million for the three months ended March 31, 2021. In October 2021, in connection with our initial public offering, the Note was automatically converted into 5,451,958 shares of our common stock and was not outstanding as of March 31, 2022.

Research and Development Programs

R&D program costs include compensation and other direct costs plus an allocation of indirect costs, based on certain assumptions.

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, and we had an accumulated deficit of $90.7 million as of March 31, 2022. 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.

In October 2021, we completed an initial public offering of 3,333,334 shares of our common stock, at a public offering price of $12.00 per share. The gross proceeds from the offering, before deducting underwriting discounts, commissions and other offering expenses, were approximately $46.0 million, which includes the exercise of the underwriters option to acquire an additional 500,000 shares at the public offering price, which shares were delivered in November 2021. Underwriting discounts, commissions and other offering expenses, were approximately $6.2 million, resulting in net proceeds of approximately $39.8 million.

Prior to our initial public offering, we had been reliant on Agenus to finance our operations. From our inception through our initial public offering in October 2021, we received funding of $45.5 million from Agenus through the Note. The Note had a $45.5 million principal balance, plus accrued and unpaid interest of $6.8 million, as of October 14, 2021, the date we priced our initial public offering. In connection of the completion of our initial public offering, the Note was automatically converted into 5,451,958 shares of our common stock and was not outstanding as of March 31, 2022.

In December 2018, we entered into an agreement with the Belgium Walloon Region Government (the “Walloon Region”) in which the Walloon Region agreed to provide a grant of €1.3 million and a repayable advance of €8.3 million for the development of one of our research programs. As of March 31, 2022, we had received $881,000 of the grant portion and $5.2 million of the repayable advance. During 2020, we discontinued research efforts related to this program and are evaluating our options in accordance with the terms of the agreement. We recognized the grant portion received as income during the years ended December 31, 2019 and 2020 and have included the repayable advance balance of $5.2 million in other current liabilities in our condensed consolidated balance sheet at March 31, 2022, while we finalize the termination of the agreement with the Walloon Region. We received a notice from the Walloon Region in February 2021 informing us that, pursuant to the terms of the agreement, they have assumed we plan to exploit the results of our research under the program and as such expect us to reimburse the repayable advance, and we have responded to the Walloon Region that we do not plan to exploit the results of such research. It is uncertain at this time if we will be obligated to repay any or all of this advance.

Our cash and cash equivalents balance as of March 31, 2022 was $34.7 million. Based on our current plans and projections we believe this cash balance will be sufficient to satisfy our liquidity requirements for more than one year from when these financial statements were issued.

Management continues to address our liquidity position and will adjust spending as needed in order to preserve liquidity. Our future liquidity needs will be determined primarily by the success of our operations with respect to the progression of our product candidates and key development and regulatory events in the future. Potential sources of additional funding include: (1) pursuing collaboration, out-licensing and/or partnering opportunities for our portfolio programs and product candidates with one or more third parties, (2) securing debt financing and/or (3) selling equity securities.

Net cash used in operating activities for both the three months ended March 31, 2022 and 2021 was $4.2 million. 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.

This Quarterly Report on Form 10-Q contains forward-looking statements. 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,” “future” and other words and terms of similar meaning. Certain forward-looking statements in this Quarterly Report on Form 10-Q can be identified by the fact that they do not relate strictly to historical or current facts. In particular, these statements relate to, among other things, our business strategy, our research and development, our ability to commercialize our product candidates, our prospects for initiating partnerships or collaborations, uncertainty regarding our future operating results and our profitability, anticipated sources of funds as well as our plans, objectives, expectations, and intentions.  Such forward-looking statements are based on current expectations and involve inherent risks and uncertainties, including factors that could delay, divert or change any of them, and could cause actual outcomes to differ materially from current expectations. Therefore, 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, except as required by law.

Some of the factors that could cause actual results to differ are identified below, as well as those discussed in the Item 1A. Risk Factors section in our Annual Report on Form 10-K for the year ended December 31, 2021. It is not possible to predict or identify all such factors. Consequently, you should not consider the following to be a complete discussion of all potential risks or uncertainties: we expect to incur losses for the foreseeable future; if we fail to raise capital, we would be forced to delay, reduce, or eliminate certain projects; raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies; we may fail to develop AGENT-797 successfully or be unable to obtain regulatory approval for it; utilizing

13

allogeneic iNKT cells represents a novel approach to immunotherapy; our product candidates will require significant additional testing before we can seek regulatory approval; we may experience delays or difficulties in the enrollment of patients in our clinical trials; serious adverse events, undesirable side effects or unexpected characteristics caused by our product candidates could delay or prevent regulatory approval or limit their commercial potential; data produced in our clinical trials is at an early stage and future data may not support continued development; if our clinical trials fail to demonstrate safety and efficacy, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of product candidates; we face significant competition and there is a possibility that our competitors may achieve regulatory approval before us or develop adoptive cell therapies that are safer or more advanced or effective than ours; product candidates we develop may be complex and difficult to manufacture; the regulatory landscape that will govern any product candidates we may develop is complex and uncertain; failure to comply with laws and regulations could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings; Agenus owns a majority of our common stock and will be able to exert control over specific matters subject to stockholder approval; certain of our directors and officers may have actual or potential conflicts of interest; we rely on third parties, which may not perform satisfactorily; if we are not able to establish collaborations, we may have to alter our development and commercialization plans which may cause delays or increase costs; we may be unable to obtain and maintain satisfactory patent and other intellectual property protection for any product candidates we develop; our rights to develop and commercialize our cell-based immunotherapies and product candidates are subject, in part, to the terms and conditions of licenses granted to us by others, including Agenus; third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property rights; we may be unable to retain our key executives and to attract, retain and motivate qualified personnel; our internal computer systems, or those of our third-party vendors, collaborators or other contractors or consultants, may fail or suffer security breaches; the continuing outbreak of COVID-19 in the United States and other countries may adversely affect our business and that of our suppliers, contract research organizations or other third parties relevant to our business; and a market for our common stock may not be sustained.

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 we have more than $1.07 billion in annual revenue, we have more than $700.0 million in market value of our stock held by non-affiliates (and we have been a public company for at least 12 months and have filed one annual report on Form 10-K) or 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 March 31, 2022 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, 2021. There have been no material changes to the risk factors described in Part I, Item 1A "Risk Factors" of our 2021 Form 10-K.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Use of Proceeds

On October 19, 2021, we closed the initial public offering of our common stock pursuant to which we issued and sold 3,333,334 shares of our common stock at a price to the public of $12.00 per share for aggregate gross proceeds of approximately $40.0 million, before deducting underwriting discounts and commissions and offering expenses payable by us. On November 3, 2021, we sold an additional 500,000 shares of our common stock pursuant to the underwriters’ option to purchase additional shares in the initial public offering at the public offering price for an additional $6.0 million in gross proceeds.

All of the shares issued and sold in the initial public offering were registered under the Securities Act pursuant to a Registration Statement on Form S-1 (File No. 333-259503), which was declared effective by the SEC on October 14, 2021. Evercore Group L.L.C and William Blair & Company, L.L.C. acted as joint book-running managers and B. Riley Securities, Inc. and Robert W. Baird & Co. Incorporation acted as co-managers of our initial public offering.

We received net proceeds of approximately $39.8 million after deducting underwriting discounts and commissions and other offering expenses. None of the underwriting discounts and commissions or offering expenses were incurred or paid to directors or officers of ours or their associates or to persons owning 10 percent or more of our common stock or to any of our affiliates.

As of March 31, 2022, we had used approximately $5.1 of the net proceeds from our initial public offering for the development of AGENT-797 and working capital and other general corporate purposes. There has been no material change in our planned use of the net proceeds from the offering as described in our Registration Statement on Form S-1.
