Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview

We are 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 and an Intellectual Property Assignment and License Agreement with Agenus. Under the Amended and Restated Intercompany Services 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. Our Phase 1 clinical trial studying agenT-797 in solid tumor cancers, as a monotherapy and in combination with anti-PD-1 checkpoint inhibitors, pembrolizumab and nivolumab, is currently advancing as a priority program. Encouraging early activity was seen with agenT-797 monotherapy and combination, with reductions in target and non-target lesions or disease stabilization in patients, which was presented at Society of Immunotherapy for Cancer (“SITC”) in 2022. We currently expect to have updated readouts from this clinical trial in 2023. We commenced a Phase 1 clinical trial of agenT-797 for the treatment of multiple myeloma and reported that agenT-797 was tolerable to 1x109 cells/dose and suppressed biomarkers associated with disease progression at SITC in 2022. This POC phase 1 underscores the potential application of INKTs in multiple myeloma and establishes important novel data to support the advancement of our armored BCMA-CAR-INKT program as a potential best in class next generation allogeneic BCMA cell therapy for these patients. Strategic discussions to advance this program are underway.

With the unique circumstances of the COVID-19 pandemic, we commenced a Phase 1 clinical trial of agenT-797 in viral ARDS and reported an encouraging survival benefit of 70%, compared to ~10-22% in an in-hospital control and time-matched data from the CDC. These data were presented at SITC 2022, and we have planned an update from the trial in the first half of 2023 and a formal scientific publication is currently in review. There are currently no approved therapies for ARDS; our data contribute favorably as a potential therapeutic and we plan to externally finance the advancement of agenT-797 in viral ARDS through strategic collaborations. Discussions are underway.

In addition, we are advancing a pipeline of next-generation allogeneic, engineered iNKT programs. Our two most advanced engineered programs are (1) MiNK-413, an IL-15 armored CAR-iNKT program targeting B cell maturation antigen (“BCMA), and (2) MiNK-215, an IL-15 armored tumor stromal targeting FAP-CAR-iNKT 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 robust 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 SITC in 2022. These programs are both in preclinical development with investigational new drug application (“IND”) enabling activities underway in 2023.

Our research and development expenses for the years ended December 31, 2022 and 2021 were $23.1 million and $14.0 million, respectively. We have incurred losses since our inception. As of December 31, 2022, we had an accumulated deficit of $110.9 million.

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 year-end cash balance will be sufficient to satisfy our liquidity requirements for more than one year from

69

when these financial statements were issued. Management continues to monitor 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. If additional funding is not obtained through these sources we have the ability to borrow certain funds from our parent company.

Historical Results of Operations

For the Year Ended December 31, 2022 Compared to the Year Ended December 31, 2021

Research and development (“R&D”) 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 increased 66% to $23.1 million for the year ended December 31, 2022 from $14.0 million for the year ended December 31, 2021. This increase is primarily due to an increase in costs associated with the advancement of our clinical trials, increased preclinical activities and increased personnel costs associated with internalization of our manufacturing activities.

General and administrative (“G&A”) expense

G&A expense consists primarily of personnel costs, facility expenses, and professional fees. G&A expense increased 69% to $7.8 million for the year ended December 31, 2022 from $4.6 million for the year ended December 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, audit and tax and insurance 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 December 31, 2022.

Other income (expense), net

Other income increased $2.5 million for the year ended December 31, 2022, from income of $0.2 million for the year ended December 31, 2021 to income of $2.7 million for the year ended December 31, 2022, due to the recognition of a $2.7 million gain on the partial forgiveness of the advance received under our research and development agreement with the Belgium Walloon Region Government (the “Walloon Region”), in the year ended December 31, 2022.

Interest income (expense), net

Interest income for the year ended December 31, 2022 was $253,000 due to interest earned on our money market funds. Interest expense related to the Note was $2.4 million for the year ended December 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 December 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.

For the years ended December 31,

70

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 $110.9 million as of December 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. 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 December 31, 2022.

In December 2018, we entered into an agreement with the Walloon Region in which the Walloon Region agreed to provide a grant of up to €1.3 million and an advance of up to €8.3 million for the development of one of our research programs. As of December 31, 2022, we had received $881,000 of the grant portion and $5.2 million of the advance. During 2020, we discontinued research efforts related to this program, and in 2021 we provided additional information as requested by the Walloon Region to terminate the agreement. We recognized the grant portion received as income during the years ended December 31, 2019 and 2020. We learned in the second quarter of 2022 that the Walloon Region had obtained a default judgment in the amount of €2,086,711.91 for repayment of the advance. In view of the default judgment, we reduced the recorded liability and recorded a gain of approximately $2.7 million in our consolidated statement of operations for the year ended December 31, 2022. We have included the remaining balance of $2.2 million in other current liabilities in our consolidated balance sheet at December 31, 2022 while we continue to evaluate the merits of the Walloon Region’s claim to the amount.

Our cash and cash equivalents balance as of December 31, 2022 was $19.6 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. If additional funding is not obtained through these sources we have the ability to borrow certain funds from our parent company.

Net cash used in operating activities for the years ended December 31, 2022 and 2021 was $18.9 million and $12.8 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.

Critical Accounting Policies and Estimates

The SEC defines “critical accounting policies” as those that require the application of management’s most difficult, subjective, or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods.

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires us 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 amounts of revenues and expenses during the reporting period. We base those estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.

Our significant accounting policies are described in Note 2 of the notes to our consolidated financial statements contained elsewhere in this Annual Report on Form 10-K. In many cases, the accounting treatment of a particular transaction is dictated by U.S. GAAP, with no need for our judgment in its application. There are also areas in which our judgment in selecting an available alternative would not produce a materially different result.

Recent Accounting Pronouncements

Refer to Note 2 to our consolidated financial statements included within Item 8 of this Annual Report on Form 10-K for a description of recent accounting pronouncements applicable to our business.

JOBS Act

We qualify as an “emerging growth company” as defined in 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.

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.

MiNK THERAPEUTICS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Description of Business

MiNK Therapeutics, Inc. (“MiNK” or the “Company”) is a clinical stage biopharmaceutical company focused on developing allogeneic invariant natural killer T (“iNKT”) cell therapies to treat cancer and other life-threatening illnesses.

Since inception, in 2017, until the completion of the Company’s initial public offering (“IPO”), the Company financed its operations primarily through funding from Agenus Inc. (“Agenus”), its parent company. The Company has incurred losses since inception and, as of December 31, 2022, had an accumulated deficit of $110.9 million. MiNK expects to continue incurring operating losses and negative cash flows for the foreseeable future. Based on the Company’s current plans and projections, MiNK believes its cash and cash equivalents balance as of December 31, 2022 of $19.6 million will be sufficient to satisfy its liquidity requirements for more than one year from when these financial statements were issued.

Management continually monitors the Company’s liquidity position and adjusts spending as needed in order to preserve liquidity. The Company’s future liquidity needs will be determined primarily by the success of its operations with respect to the progression of the Company’s product candidates and key development and regulatory events in the future. Potential sources of additional funding for the Company include: (1) pursuing collaboration, out-licensing and/or partnering opportunities for the Company’s portfolio programs and product candidates with one or more third parties, (2) securing debt financing and/or (3) selling equity securities. If additional funding is not obtained through these sources the Company has the ability to borrow certain funds from its parent company.

MiNK’s product candidates are in various stages of development and significant 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) Summary of Significant Accounting Policies

(a) Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of MiNK and its subsidiaries. All significant intercompany transactions and accounts have been eliminated in consolidation.

(b) Segment Information

MiNK is managed and operated as one business segment. The entire business is managed by a single executive operating committee that reports to the chief executive officer. The Company does not operate separate lines of business with respect to any of its product candidates or geographic locations. Accordingly, the Company does not prepare discrete financial information with respect to separate product areas or by location and does not have separately reportable segments as defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 280, Segment Reporting.

(c) Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires the Company 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases those estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.

(d) Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with maturities at acquisition of three months or less to be cash equivalents. Cash equivalents consist primarily of money market funds.

80

(e) Equipment

Equipment is carried at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, typically 4-10 years. Additions are capitalized, while repairs and maintenance are charged to expense as incurred. Depreciation expense was $122,000 and $78,000, for the years ended December 31, 2022 and 2021, respectively.

(f) Fair Value Option

Under the Fair Value Option subsection of ASC Subtopic 825-10, Financial Instruments – Overall, the Company has the irrevocable option to report most financial assets and liabilities at fair value on an instrument-by-instrument basis with changes in fair value reported in earnings. The Company elected to report the convertible affiliated note, as amended, it issued to Agenus (the “Note”) at fair value. The fair value of the Note was determined on a scenario based present value methodology. In connection with the Company’s IPO, the Note was automatically converted into 5,451,958 shares of the Company’s common stock and was not outstanding as of December 31, 2022 or 2021.

(g) Fair Value Measurements

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

The Company’s cash and cash equivalents are carried at fair value (a Level 1 measurement), determined according to the fair value hierarchy described above. The carrying values of the Company’s, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these liabilities.

(h) Foreign Currency Transactions

Gains and losses from the Company’s foreign currency-based accounts and transactions, such as those resulting from the remeasurement and settlement of receivables and payables denominated in foreign currencies, are included in the consolidated statements of operations within other income (expense). The Company recorded foreign currency losses of $14,000 and $407,000 for the years ended December 31, 2022 and 2021, respectively.

(i) Research and Development

Research and development expenses include the costs associated with the Company’s internal research and development activities, including salaries and benefits, share-based compensation, occupancy costs, clinical manufacturing costs, related administrative costs and research and development conducted for the Company by outside advisors. Research and development expenses also include the cost of clinical trial materials shipped to the Company’s research partners. Research and development costs are expensed as incurred.

(j) Share-Based Compensation

MiNK accounts for share-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation. Share-based compensation expense is recognized based on the estimated grant date fair value. Compensation cost is recognized on a straight-line basis over the requisite service period of the award. Forfeitures are recognized as they occur. See Note 8 for further discussion on share-based compensation.

81

(k) Income Taxes

Income taxes are accounted for under the asset and liability method with deferred tax assets and liabilities recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which such items are expected to be reversed or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the consolidated statement of operations in the period that includes the enactment date. Deferred tax assets are recognized when they are more likely than not expected to be realized.

(l) Net Loss Per Share

Basic income or loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding. Diluted income per common share is calculated by dividing net income attributable to common stockholders 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 attributable to common stockholders 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 December 31, 2022 and 2021, as they would be anti-dilutive:

(m) Recent Accounting Pronouncements

No new accounting pronouncement issued or effective during the year ended December 31, 2022 had or is expected to have a material impact on the Company’s consolidated financial statements or disclosures.

(3) Cash and Cash Equivalents

Cash equivalents consisted of the following as of as of December 31, 2022 (in thousands):

Cost Estimated Fair Value

(4) Equipment

Equipment, net, consist of the following as of December 31, 2022 and 2021 (in thousands):

The Company is subject to taxation in the United States and in various state, local and foreign jurisdictions. The Company remains subject to examination by U.S. Federal, state, local and foreign tax authorities for tax years 2019 through 2022. With few exceptions, the Company is no longer subject to U.S. Federal state, and foreign examinations by tax authorities for the tax year 2018. However, net operating losses from the tax year 2018 would be subject to examination if and when used in a future tax return to offset taxable income. The Company’s policy is to recognize income tax related penalties and interest, if any, in its provision for income taxes and, to the extent applicable, in the corresponding income tax assets and liabilities, including any amounts for uncertain tax positions.

As of December 31, 2022, the Company had available net operating loss carryforwards of $43.4 million and $40.4 million for Federal and state income tax purposes, respectively, which are available to offset future Federal and state taxable income, if any. $43.2 million

82

of these Federal net operating loss carryforwards do not expire, while the remaining net operating loss carryforwards expire in 2037. The Company’s ability to use these net operating losses is limited by change of control provisions under Internal Revenue Code Section 382 and may expire unused. The Company also has foreign net operating loss carryforwards, which do not expire, available to offset future foreign taxable income of $14.0 million generated in the United Kingdom, $9.1 million in Belgium and $289,000 in Hong Kong. The potential impacts of these provisions are among the items considered and reflected in the Company’s assessment of its valuation allowance requirements.

Beginning January 1, 2022, the Tax Cuts and Jobs Act (the "Tax Act") eliminated the option to deduct research and development expenditures in the current year and requires taxpayers to capitalize such expenses pursuant to Internal Revenue Code ("IRC") Section 174. The capitalized expenses are amortized over a 5-year period for domestic expenses and a 15-year period for foreign expenses. We have included the impact of this provision, which results in additional deferred tax assets of approximately $4.2 million as of December 31, 2022.

The tax effect of temporary differences and net operating loss carryforwards that give rise to significant portions of the deferred tax assets and deferred tax liabilities as of December 31, 2022 and 2021 are presented below (in thousands).

Deferred tax assets:

U.S. Federal and state net operating loss carryforwards $ 11,411 $ 12,356

Foreign net operating loss carryforwards 6,224 5,641

Share-based compensation 441 472

Capitalized research expenses 4,154 —

Net deferred tax assets $ — $ —

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which the net operating loss and tax credit carryforwards can be utilized or the temporary differences become deductible. The Company considers projected future taxable income and tax planning strategies in making this assessment. To fully realize the deferred tax asset, the Company will need to generate future taxable income sufficient to utilize net operating losses prior to their expiration. Based upon the Company’s history of not generating taxable income, the Company believes that it is more likely than not that deferred tax assets will not be realized through future earnings. Accordingly, a valuation allowance has been established for the full value of the deferred tax assets. The valuation allowance on the deferred tax assets increased by $4.0 million and $7.3 million during the years ended December 31, 2022 and 2021, respectively.

Income tax benefit was nil for the years ended December 31, 2022 and 2021. Income taxes recorded differed from the amounts computed by applying the U.S. Federal income tax rate of 21% in 2022 and 2021 to loss before income taxes as a result of the following (in thousands).

(7) Equity

In September 2021, the Company effected a 2.783-for-one split of the Company’s common stock. All common share, per share and related information included in the accompanying financial statements have been adjusted retroactively, where applicable, to reflect the split.

In September 2021, the Company’s stockholders approved an amendment to the Company’s Amended and Restated Certificate of Incorporation, to increase the number of authorized shares of common stock to 35,000,000, with a par value $0.00001 per share. In connection with the Company’s IPO, the Company’s authorized capital stock increased to 155,000,000 shares, all with a par value of $0.00001 per share, of which:

150,000,000 shares are designated as common stock; and

5,000,000 shares are designated as preferred stock.

In October 2021, the Company completed an IPO of 3,333,334 shares of its 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. Subsequent to the completed offering, the Company continues to be majority owned by Agenus.

In October 2021, in connection with the Company’s IPO, the Note was automatically converted into 5,451,958 shares of the Company’s common stock. Refer to Note 10 for additional detail.

(8) Share-based Compensation Plans

The Company’s 2018 Equity Incentive Plan (the “2018 Plan”) provided for the grant of incentive stock options intended to qualify under Section 422 of the Internal Revenue Code, nonstatutory stock options, restricted stock, unrestricted stock and other equity-based awards, such as stock appreciation rights, and stock units including restricted stock units for up to approximately 13.9 million shares of the Company’s common stock (subject to adjustment in the event of stock splits and other similar events). As of December 31, 2022, no shares remain available for issuance under the 2018 Plan.

In connection with the Company’s IPO, MiNK’s board of directors adopted the MiNK Therapeutics, Inc. 2021 Equity Incentive Plan (the “2021 Plan”). The 2021 Plan provides for the grant of incentive stock options intended to qualify under Section 422 of the Code, nonstatutory stock options, restricted stock, unrestricted stock and other equity-based awards, for an initial share pool of approximately 6.1 million shares of the Company’s common stock (subject to adjustment in the event of stock splits and other similar events). The initial share pool will automatically increase on January 1st of each year from 2023 to 2031 by the lesser of (i) four percent of the number of shares of the Company’s common stock outstanding as of the close of business on the immediately preceding December 31st and (ii) the number of shares determined by the Company’s board of directors on or prior to such date for such year. In January 2022, the 2021 Plan share pool increased by approximately 1.3 million shares. As of December 31, 2022, there were approximately 7.4 million shares reserved for issuance under the 2021 Plan.

In connection with the Company’s IPO, MiNK’s board of directors adopted the MiNK Therapeutics, Inc. 2021 Employee Stock Purchase Plan (the “ESPP”). The ESPP provides eligible employees the opportunity to acquire the Company’s common stock in a program designed to comply with Section 423 of the Code. There are approximately 710,000 shares reserved for issuance under the ESPP, plus an automatic annual increase on January 1st of each year from 2023 to 2031 equal to the lesser of (i) one percent of the

84

number of shares of the Company’s common stock outstanding as of the close of business on the immediately preceding December 31st and (ii) the number of shares determined by the Company’s board of directors on or prior to such date for such year, up to a maximum of approximately 3.5 million shares in the aggregate.

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, service conditions, and generally vest ratably over a 3 or 4-year period.

The fair value of each option granted during the period was estimated on the date of grant using the following weighted average assumptions:

Expected volatility 81 % 67 %

Expected term in years 6 6

Risk-free interest rate 1.7 % 0.6 %

Dividend yield 0 % 0 %

The expected term of stock options granted is based on historical data and other factors and represents the period of time that stock options are expected to be outstanding prior to exercise. The risk-free interest rate is based on U.S. Treasury strips with maturities that match the expected term on the date of grant.

A summary of option activity for 2022 is presented below:

The weighted average grant-date fair values of options granted during the years ended December 31, 2022 and 2021, was $2.20 and $1.76, respectively. During both 2022 and 2021, all options were granted with exercise prices equal to the market value of the underlying shares of common stock on the grant date.

The aggregate intrinsic value in the table above represents the difference between the Company's closing stock price on the last trading day of fiscal 2022 and the exercise price, multiplied by the number of in-the-money options that would have been received by the option holders had all option holders exercised their options on December 31, 2022 (the intrinsic value is considered to be zero if the exercise price is greater than the closing stock price). This amount changes based on the fair market value of the Company's stock. The total intrinsic value of options exercised during the year ended December 31, 2022, determined on the dates of exercise, was approximately $0.5 million.

As of December 31, 2022, there was $4.8 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 2.5 years. For awards with performance conditions, expense is recognized if the underlying performance conditions are deemed probable of achievement.

A summary of non-vested stock activity for 2022 is presented below:

85

NonvestedShares WeightedAverageGrant DateFair Value

As of December 31, 2022, there was $0.8 million of unrecognized share-based compensation expense related to these non-vested shares which will be recognized over a weighted average period of 0.7 years. The total intrinsic value of shares vested during the year ended December 31, 2022 was $0.6 million.

The Company issues new shares upon option exercises and vesting of non-vested stock. During the years ended December 31, 2022 and 2021, 258,648 shares and 41,746 shares, respectively, were issued as a result of stock option exercises. During the year ended December 31, 2022, 60,595 shares were issued as a result of the vesting of non-vested stock. Additionally, during the year ended December 31, 2022, 125,199 shares were issued as payment for certain employee bonuses, with 43,665 of those shares being withheld to cover taxes, resulting in a net share issuance of 81,534.

Stock based compensation expense also includes expense related to awards granted to employees of the Company from the Agenus 2019 Equity Incentive Plan. The impact on the Company’s results of operations from share-based compensation for the year ended December 31, 2022 and 2021, was as follows (in thousands):

Research and development $ 435 $ 200

Total share-based compensation expense $ 3,027 $ 1,745

(9) Research and Development Agreement

In December 2018, the Company entered into an agreement with the Belgium Walloon Region Government ("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 the Company’s research programs. During 2020, the Company discontinued research efforts related to this program.

Other current liabilities of $2.2 million and $5.3 million as of December 31, 2022 and December 31, 2021, respectively, represent the remaining amount of the advance received.

In 2022, the Company received notice that the Walloon Region had obtained a default judgment seeking repayment of approximately $2.2 million of the advance based upon the Company allegedly not providing required notification that research and operations in the region were discontinued. The Company reduced the recorded liability from the prior total of all amounts received under the advance from the Walloon Region, to the $2.2 million repayment that would be due based on the default judgment, and recorded a gain of approximately $2.7 million in “other income (expense), net” on its consolidated statement of operations for the year ended December 31, 2022. The Company continues to evaluate its options relating to the default judgement and the remaining outstanding liability.

(10) Related Party Transactions

Until the completion of its 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 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,

86

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 has the sole responsibility to develop, manufacture and commercialize products under this New Assignment and License Agreement. 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 they believe 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 (inclusive of a cGMP manufacturing suite) 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 $2.0 and $2.4 million for the years ended December 31, 2022 and 2021, respectively, is included in Operating expenses in the Company’s statement of operations and comprehensive loss and Due to related parties, of $9.1 million as of December 31, 2022, in the Company’s consolidated balance sheet. During 2023, Agenus agreed not to require repayment of this balance prior to March 31, 2024.

Effective April 12, 2022, the Company entered into a Master Services Agreement with Atlant Clinical Ltd. (“Atlant”), a subsidiary of Agenus, to provide clinical trial support services to the Company, including an eTMF platform, medical monitoring and data manager services. The Company’s Audit and Finance Committee approved the engagement under its related-party transactions policy for up to $250,000 in services. As of December 31, 2022, the Company had entered into work orders with Atlant totaling approximately $157,000, plus out of pocket expenses which are to pass through to Company at cost. For the year ended December 31, 2022, approximately $106,500 related to these services is included in “Research and development” expense in the Company’s consolidated statements of operations.

The Company's CEO's spouse is a partner in the law firm of Wolf, Greenfield & Sachs, P.C. (“Wolf Greenfield”), which provided legal services to the Company in 2022 and 2021 and continues to do so. In the years ended December 31, 2022 and 2021, the Company paid Wolf Greenfield fees totaling approximately $343,000 and $82,000, respectively. The Company's CEO’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 both years was an insignificant amount of Wolf Greenfield’s annual revenues. The Company’s Audit and Finance Committee approved these services under its related-party transactions policy.

87

In accordance with the terms of the Note, interest was computed on the basis of a 360-day year at 8% and accrued but was not payable until converted or paid. The Note was automatically converted, at a rate 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 Company’s common stock sold in the Company’s IPO, into 5,451,958 shares of the Company’s common stock upon completion of the IPO in October 2021, and was not outstanding at December 31, 2022.

(11) Other Long-Term Liabilities

In May 2020, the Company entered into a promissory note with Bank of America, NA for aggregate loan proceeds of $356,000 (the “Loan”) under the Small Business Administration Paycheck Protection Program of the Coronavirus Aid, Relief and Economic Security Act of 2020.In September 2021, the Company received notification that its forgiveness application was approved. As such, the Loan was extinguished, and for the year ending December 31, 2021, a $356,000 gain was recorded in the Company’s consolidated statements of operations and comprehensive loss.

(12) Fair Value Measurement

The Company measured the Note at fair value. In connection with the Company’s IPO, the Note was automatically converted into 5,451,958 shares of the Company’s common stock and was not outstanding as of December 31, 2021. The impact of the change in the fair value for the year ended December 31, 2021 was $9.8 million.

(13) 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. Furthermore, litigation consumes both cash and management attention.

(14) Benefit Plans

The Company’s employees are eligible to participate in the Agenus Inc. 401(k) Savings Plan in the United States and a defined contribution Group Personal Pension Plan in the United Kingdom (the “Plans”) for all eligible employees, as defined in the Plans. Participants may contribute a portion of their compensation, subject to a maximum annual amount, as established by the applicable taxing authority. Each participant is fully vested in his or her contributions and related earnings and losses. For the years ended December 31, 2022 and 2021, the Company expensed $131,000 and $86,000, respectively, related to the discretionary contribution to the Plans.

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 22 headings are on that chain and 16 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
