    EXPLANATORY NOTE

    This Amendment No. 1 on Form 10-K/A (this “Amendment”) is filed with respect to our Annual Report on Form 10-K for the year ended December 31, 2024 (the “Original Filing”), filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2025. We are filing this Amendment for the purpose of (i) including the information required by Part III of Form 10-K, which information was omitted from the Original Filing in reliance on General Instruction G(3) to Form 10-K, which permits the information required by Part III of Form 10-K to be incorporated by reference from a registrant’s definitive proxy statement if it is filed with the SEC no later than 120 days after the fiscal year end and (ii) updating certain of our exhibits that were filed in the Original Filing.

    We do not intend to file a definitive proxy statement for our 2025 annual meeting of stockholders within 120 days of the end of our fiscal year ended December 31, 2024. Accordingly, this Amendment is being filed, in part, to provide the information required by Items 10 through 14 of Part III of the Original Filing and delete the reference on the cover page of the Original Filing to the incorporation by reference of portions of our definitive proxy statement into Part III of the Original Filing. In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), new certifications by our principal executive officer and principal financial officer are filed herewith as exhibits to this Amendment pursuant to Rule 13a-14(a) of the Exchange Act; accordingly, Item 15 of Part IV of the Original Filing has also been amended to reflect the filing of these new exhibits. Because no financial statements are being filed in this Amendment, and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. We are also not filing new certifications required under Section 906 of the Sarbanes-Oxley Act of 2002 or a new consent of our independent registered public accounting firm.

    This Amendment speaks as of the date of the Original Filing and, except as described above, this Amendment makes no changes to the Original Filing. This Amendment does not amend, update or change the financial statements or any other information presented in the Original Filing and does not otherwise reflect events occurring after the date of the Original Filing. Accordingly, this Amendment should be read in conjunction with our filings with the SEC subsequent to the filing of the Original Filing.

    Unless indicated otherwise, throughout this Amendment, references to the “Company,” “Carisma,” “we,” “us,” and “our” refer to Carisma Therapeutics Inc. (formerly Sesen Bio, Inc.) and its consolidated subsidiaries.

    References to “Legacy Carisma” refer to CTx Operations, Inc. (formerly CARISMA Therapeutics Inc.) and references to “Sesen Bio” refer to Sesen Bio, Inc. prior to completion of the business combination on March 7, 2023 in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated as of September 20, 2022, as amended, by and among the Company, Legacy Carisma and Seahawk Merger Sub, Inc., a wholly owned subsidiary of the Company, pursuant to which Seahawk Merger Sub, Inc. merged with and into Legacy Carisma, with Legacy Carisma continuing as a wholly owned subsidiary of the Company and the surviving corporation of the merger (the “Merger”).

    Composition of the Board of Directors

    Our board of directors currently consists of seven members. In accordance with the terms of our Restated Certificate of Incorporation, our board of directors is divided into three classes (Class I, Class II and Class III), with members of each class serving staggered three-year terms. The members of the classes are divided as follows:

    •the Class I directors are currently John Hohneker, M.D. and Sohanya Cheng, and their term expires at the annual meeting of stockholders to be held in 2027;
    •the Class II directors are Steven Kelly, Briggs Morrison, M.D. and Sanford Zweifach, and their term expires at the annual meeting of stockholders to be held in 2025; and
    •the Class III directors are David Scadden, M.D. and Marella Thorell, and their term expires at the annual meeting of stockholders to be held in 2026.

    Committees of our Board of Directors

    Our board of directors has an established audit committee, compensation committee, nominating and corporate governance committee and science committee, each of which operates pursuant to a charter adopted by our board of directors, and each such committee reviews its respective charter at least annually. We have posted a current copy of the charter for each of the audit committee, compensation committee, nominating and corporate governance committee and science committee on the “Governance” section of the “For Investors” section of our website, which is located at www.carismatx.com. Our board of directors also appoints from time-to-time ad hoc committees to address specific matters.

    Audit Committee and Audit Committee Financial Expert

    The members of our audit committee are currently Marella Thorell, Sohanya Cheng and Sanford Zweifach. Marella Thorell currently serves as chair of the audit committee. Michael Torok previously served as the chair of the audit committee from the closing of the Merger through his resignation, effective October 31, 2024. Regina Hodits served as a member of the audit committee from the closing of the Merger through her resignation, effective June 30, 2024.

    Our board of directors has determined that Mses. Thorell and Cheng and Mr. Zweifach each satisfy the independence standards for such committee established by the SEC and the Nasdaq Stock Market.

    All audit and non-audit services, other than de minimis non-audit services, to be provided to us by our independent registered public accounting firm must be approved in advance by our audit committee. Our board of directors has determined that Marella Thorell is an “audit committee financial expert” as defined in applicable SEC rules and that each of the members of our audit committee possesses the financial sophistication required for audit committee members under Nasdaq rules. We believe that the composition of our audit committee meets the requirements for independence under current Nasdaq and SEC rules and regulations.

    Code of Business Conduct and Ethics

    We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. We have posted a current copy of the code on the “Governance” section of the “For Investors” section of our website, which is located at www.carismatx.com. In addition, we intend to post on our
    6


    website all disclosures that are required by law or Nasdaq listing standards concerning any amendments to, or waivers from, any provision of the code.

    Insider Trading Policy; Anti-Hedging and Pledging

    We have adopted an insider trading policy governing the purchase, sale and/or other dispositions of company securities by our directors, officers, employees and other covered persons. We believe the insider trading policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and Nasdaq listing standards. A copy of our insider trading policy is filed as Exhibit 19.1 to the Original Filing. The Company also does not engage in transactions in company securities while in possession of material nonpublic information concerning the Company or its securities.

    Our insider trading policy, among other things, expressly prohibits our directors, officers, employees and other covered persons from engaging in any short sales, including short sales “against the box”, any purchases or sales of puts, calls or other derivative securities, or any purchases of financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our securities. In addition, our insider trading policy expressly prohibits such persons from purchasing our securities on margin, borrowing against our securities held in a margin account, or pledging our securities as collateral for a loan, with an exception in extraordinary situations for pledges of our securities as collateral for a loan (other than a margin loan) only after certain prerequisites are met and only with the preapproval of our principal financial officer or general counsel.


    Item 11. EXECUTIVE COMPENSATION

    Executive and Director Compensation Processes

    Our executive compensation program is administered by the compensation committee of our board of directors, subject to the oversight and approval of our board of directors. Our compensation committee reviews our executive compensation practices on an annual basis and based on this review approves, or, as appropriate, makes recommendations to our board of directors for approval of, our executive compensation program. Our director compensation program is administered by our board of directors based on recommendations by the compensation committee. Our compensation committee periodically reviews our director compensation program and makes recommendations to the board of directors with respect thereto.

    In designing our executive compensation program and our director compensation program, our compensation committee considers compensation data from comparable publicly traded companies in the biotechnology and the biopharmaceutical industry (based on, among other things, industry market capitalization, headcount and location) provided by our independent compensation consultant, Pearl Meyer & Partners LLC (“Pearl Meyer”).

    During 2024, our compensation committee retained Pearl Meyer to advise the compensation committee on our compensation program for executive officers, which includes base salaries, annual performance-based cash bonuses, annual equity incentive awards and severance arrangements, and on the director compensation program, which includes board and committee fee retainers and equity awards. The compensation committee established a peer group. The compensation consultants made recommendations with respect to the amount and form of executive officer and director compensation. Although our compensation committee considers the advice and guidance of the compensation consultants as to our executive compensation program and our director compensation program, our compensation committee ultimately makes its own decisions about these matters. In the future, we expect that our compensation committee will continue to engage independent compensation consultants to provide additional guidance on our executive and director compensation programs and to conduct further competitive benchmarking against a peer group of publicly traded companies.

    The compensation committee reviewed information regarding the independence and potential conflicts of interest of Pearl Meyer, taking into account, among other things, the factors set forth in the Nasdaq listing standards. Based on such review, the compensation committee concluded that the engagement of Pearl Meyer did not raise any conflict of interest.

    Equity Incentives
    9



    Although we do not have a formal policy with respect to the grant of equity incentive awards to our executive officers, we believe that equity grants provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executive officers and our stockholders. Accordingly, we use stock options to compensate our executive officers in the form of initial grants in connection with the commencement of employment and also at various other times, based on performance. In addition, we believe that equity grants vesting over a four-year period promote executive retention because this feature incentivizes executive officers to remain in Carisma’s employment during the vesting period. Prior to completion of the Merger, all Carisma options were granted pursuant to the CARISMA Therapeutics Inc. 2017 Stock Incentive Plan the (“2017 Plan”). Upon completion of the Merger, the 2017 Plan was assumed by the company. Option awards issued to our executives during the 2023 fiscal year were granted pursuant to the 2014 Plan which the company adopted on March 7, 2023. See “2014 Plan” below for additional information. Prior to the exercise of an option under the 2014 Plan, the holder has no rights as a stockholder with respect to the shares subject to such option, including no voting rights and no right to receive dividends or dividend equivalents. We have historically granted stock options with exercise prices equal to the fair market value of our common stock on the date of grant as determined by our board of directors.

    In January 2025, we granted option awards with respect to 500,000 and 221,000 shares of our common stock to Mr. Kelly and Dr. Klichinsky, respectively. The shares underlying these option awards vest over four years in equal monthly installments, subject to continued service.

    In June 2024, we granted an option award with respect to 125,000 shares of our common stock to Mr. Kelly and option awards with respect to 85,000 shares of our common stock to each of Mr. Morris and Dr. Klichinsky. The shares underlying these option awards vest over two years, with 50% of the shares vesting on June 17, 2025 and the remaining 50% of the shares vesting on June 17, 2026, subject to continued service. In connection with Mr. Morris’ termination which became effective December 31, 2024, the board of directors approved the acceleration of the first 50% installment of the special retention option to purchase 85,000 shares of common stock granted to Mr. Morris with an effective grant date of June 17, 2024, which would have vested in June 2025.

    In January 2024, we granted an option award with respect to 438,000 shares of our common stock to Mr. Kelly and option awards with respect to 170,500 shares of our common stock to each of Mr. Morris and Dr. Klichinsky. The shares underlying these option awards vest over four years in equal monthly installments, subject to continued service.

    In June 2023, we granted an option award with respect to 600,000 shares to Mr. Kelly and option awards with respect to 238,000 shares of our common stock to each of Mr. Morris and Dr. Klichinsky. The shares underlying these option awards vest over four years, with 25% of the shares vesting on June 6, 2024 and the remaining 75% of the shares vesting over the next three years thereafter in equal monthly installments until June 6, 2027, subject to continued service.

Shares of our common stock issued under the 2014 Plan may consist in whole or in part of authorized but unissued shares or treasury shares.

    For purposes of counting the number of shares available for the grant of awards under the 2014 Plan, all shares of common stock covered by SARs will be counted against the number of shares available for the grant of awards. However, SARs that may be settled only in cash will not be so counted. In addition, if we grant a SAR in tandem with an option for the same number of shares of our common stock and which provides that only one such award may be exercised, (“tandem SAR”), only the shares covered by the option, and not the shares covered by the tandem SAR, will be so counted, and the expiration of one in connection with the other’s exercise will not restore shares to the 2014 Plan.

    Shares covered by awards under the 2014 Plan that expire or are terminated, surrendered, or cancelled without having been fully exercised or are forfeited in whole or in part (including as the result of shares subject to such award being repurchased by us at the original issuance price pursuant to a contractual repurchase right) or that result in any shares not being issued (including as a result of a SAR that was settleable either in cash or in stock actually being settled in cash) will again be available for the grant of awards under the 2014 Plan (subject, in the case of incentive stock options, to any limitations under the Code). In the case of the exercise of a SAR, the number of shares counted against the shares available for the grant of awards under the 2014 Plan will be the full number of shares subject to the SAR multiplied by the percentage of the SAR actually exercised, regardless of the number of shares actually used to settle the SAR upon exercise, and the shares covered by a tandem SAR will not again become available for grant upon the expiration or termination of the tandem SAR.

    Shares of our common stock that are delivered (by actual delivery, attestation, or net exercise) to us by a participant to purchase shares of our common stock upon exercise of an award or to satisfy tax withholding obligations (including shares retained from the award creating the tax obligation) will be added back to the number of shares available for the future grant of awards under the 2014 Plan.

    In connection with a merger or consolidation of an entity with us or our acquisition of property or stock of an entity, our board of directors may grant awards under the 2014 Plan in substitution for any options or other stock or stock-based awards granted by such entity or an affiliate thereof on such terms as our board of directors determines appropriate in the circumstances, notwithstanding any limitation on awards contained in the 2014 Plan. No such substitute awards shall count against the overall share limit, except as required by reason of Section 422 and related provisions of the Code.

    Descriptions of Awards Options. A participant who is awarded an option receives the right to purchase a specified number of shares of our common stock at a specified exercise price and subject to the other terms and conditions that are specified in connection with the award agreement. An option that is not intended to be an “incentive stock option” is a “nonstatutory stock option.” Options may not be granted at an exercise price that is less than 100% of the fair market value of our common stock on the date of grant. If our board of directors approves the grant of an option with an exercise price to be determined on a future date, the exercise price may not be less than 100% of the fair market value of our common stock on that future date. Under present law, incentive stock options may not be granted at an exercise price less than 110% of the fair market value in the case of stock options granted to participants who hold more than 10% of the total combined voting power of all classes of our stock or any of our subsidiaries. Under the terms of the 2014 Plan, options may not be granted for a term in excess of ten years (and, under present law, five years in the case of incentive stock options granted to participants who hold greater than 10% of the total combined voting power of all classes of our stock or any of our subsidiaries).

    The 2014 Plan permits participants to pay the exercise price of options using one or more of the following manners of payment: (i) payment by cash or by check, (ii) except as may otherwise be provided in the applicable award agreement or approved by our board of directors, in connection with a “cashless exercise” through a broker, (iii) to the extent provided in the applicable award agreement or approved by the our board of directors, and subject to certain conditions, by delivery to us (either by actual delivery or attestation) of shares of common stock owned by the participant valued at their fair market value, (iv) to the extent provided in an applicable nonstatutory stock option award agreement or approved by our board of directors, by delivery of a notice of “net exercise” as a result of which we will retain a number of shares of our common stock otherwise issuable pursuant to the stock option equal to the
    15


    aggregate exercise price for the portion of the option being exercised divided by the fair market value of our common stock on the date of
    exercise, (v) to the extent permitted by applicable law and provided for in the applicable award agreement or approved by our board of directors, by any other lawful means as our board of directors may determine, or (vi) by any combination of these forms of payment.

    Stock Appreciation Rights. A participant who is awarded a SAR receives, upon exercise, a number of shares of our common stock, or cash (or a combination of shares of our common stock and cash) determined by reference to appreciation, from and after the date of grant, in the fair market value of a share of our common stock over the measurement price. The 2014 Plan provides that the measurement price of a SAR may not be less than 100% of the fair market value of our common stock on the date the SAR is granted (provided, however, that if our board of directors approves the grant of a SAR effective as of a future date, the measurement price will not be less than 100% of the fair market value on such future date) and that SARs may not be granted with a term in excess of 10 years.

    Limitation on Repricing of Options or SARs. With respect to options and SARs, unless such action is approved by our stockholders or otherwise permitted under the terms of the 2014 Plan in connection with certain changes in capitalization and reorganization events, we may not (1) amend any outstanding option or SAR granted under the 2014 Plan to provide an exercise price or measurement price per share that is lower than the then-current exercise price or measurement price per share of such outstanding option or SAR, (2) cancel any outstanding option or SAR (whether or not granted under the 2014 Plan) and grant in substitution for such awards new awards under the 2014 Plan (other than certain substitute awards issued in connection with a merger or consolidation of an entity with us or an acquisition by us, described above) covering the same or a different number of shares of our common stock and having an exercise price or measurement price per share lower than the then-current exercise price or measurement price per share of the canceled option or SAR, (3) cancel in exchange for a cash payment any outstanding option or SAR with an exercise price or measurement price per share above the then-current fair market value of our common stock, or (4) take any other action under the 2014 Plan that constitutes a “repricing” within the meaning of the rules of Nasdaq.

    Restricted Stock Awards. A participant who is granted an award of restricted stock is entitled to acquire shares of our common stock, subject to our right to repurchase all or part of such shares at their issue price or other stated or formula price (or to require forfeiture of such shares if issued at no cost) in the event that the conditions specified in the applicable award are not satisfied prior to the end of the applicable restriction period established for such award. Unless otherwise provided in the applicable award agreement, any dividends (whether paid in cash, stock or property) declared and paid by us with respect to shares of restricted stock will be paid to the participant only if and when such shares become free from the restrictions on transferability and forfeitability that apply to such shares.

    Restricted Stock Unit Awards. A participant who is granted an RSU award is entitled to receive shares of our common stock, or cash equal to the fair market value of such shares or a combination of cash and shares, to be delivered at the time such award vests or on a deferred basis pursuant to the terms and conditions established by our board of directors. Our board of directors may provide that settlement of RSUs will be deferred, on a mandatory basis or at the election of the participant, in a manner that complies with Section 409A of the Code. A participant has no voting rights with respect to any RSU. An RSU award agreement may provide the applicable participant with the right to receive an amount equal to any dividends or other distributions declared and paid on an equal number of outstanding shares of our common stock. Any such dividend equivalents may be settled in cash and/or shares of our common stock and may be subject to the same restrictions on transfer and forfeitability as the RSUs with respect to which such dividend equivalents are awarded, in each case to the extent provided in the applicable award agreement.

    Other Stock-Based Awards. Under the 2014 Plan, our board of directors may grant other awards of shares of our common stock, and other awards that are valued in whole or in part by reference to, or are otherwise based on, shares of our common stock or other property, having such terms and conditions as our board of directors may determine. We refer to these types of awards as other stock-based awards. Other stock-based awards may be available as a form of payment in settlement of other awards granted under the 2014 Plan or as payment in lieu of compensation to which a participant is otherwise entitled. Other stock-based awards may be paid in shares of our common stock or in cash, as our board of directors may determine.

    Eligibility to Receive Awards

    16


    All of our employees, officers, directors, consultants or advisors are eligible to participate in the 2014 Plan.

    Transferability of Awards

    Awards may not be sold, assigned, transferred, pledged or otherwise encumbered by a participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution or, other than in the case of an incentive stock option, pursuant to a qualified domestic relations order. During the life of the participant, awards are exercisable only by the participant. However, our board of directors may permit or provide in an award for the gratuitous transfer of the award by the participant to or for the benefit of any immediate family member, family trust or other entity established for the benefit of the participant and/or an immediate family member thereof if we would be eligible to use a Form S-8 under the Securities Act of 1933, as amended, for the registration of the sale of the common stock subject to such award to the proposed transferee. Further, we are not required to recognize any such permitted transfer until such time as the permitted transferee has, as a condition to the transfer, delivered to us a written instrument in form and substance satisfactory to us confirming that such transferee will be bound by all of the terms and conditions of the award. None of the restrictions described in this paragraph prohibit a transfer from the participant to us.

    No Rights as a Stockholder

    Subject to the provisions of the applicable award, no participant or designated beneficiary will have any rights as a stockholder with respect to any shares of our common stock to be distributed with respect to an award granted under the 2014 Plan until becoming a record holder of such shares of our common stock.

    Term

    The 2014 Plan will terminate automatically on March 6, 2033 (but any awards previously granted under the 2014 Plan may extend beyond such date) unless it is earlier terminated by our board of directors.

    2017 Plan

    The Legacy Carisma board of directors adopted, and the Legacy Carisma stockholders approved, the 2017 Plan in September 2017. The 2017 Plan was amended on June 22, 2018, December 21, 2020, November 9, 2021 and April 7, 2022 to increase the number of shares of Legacy Carisma common stock available for issuance under the 2017 Plan. At the effective time of the Merger, we assumed the 2017 Plan and each Legacy Carisma option in accordance with the terms of the 2017 Plan and the applicable stock option agreements evidencing by which such Legacy Carisma options. The material terms of the 2017 Plan are summarized below.

    The 2017 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock, RSUs and other stock-based awards. Legacy Carisma’s employees, officers, directors, as well as its consultants and advisors, were eligible to receive awards under the 2017 Plan. Incentive stock options, however, were only granted to Legacy Carisma employees. Following the closing of the Merger, no further awards will be granted pursuant to the 2017 Plan.

    Authorized Shares

    As of March 7, 2023, the closing date of the Merger, Legacy Carisma had reserved an aggregate of 2,664,018 shares of Legacy Carisma common stock for the issuance of awards under the 2017 Plan. As of immediately prior to the effective time of the Merger, 1,802,979 Legacy Carisma stock options were issued and outstanding under the 2017 Plan to purchase shares of Legacy Carisma common stock at a weighted average exercise price of $1.92 per share.

    At the effective time, each Legacy Carisma option outstanding and unexercised immediately prior to the effective time, whether or not vested, was converted into an option of the Company. From and after the effective time, each Legacy Carisma option assumed by the Company may be exercised for such number of shares of the Company’s common stock as is determined by multiplying the number of shares of Legacy Carisma common stock subject to the Legacy Carisma option, as in effect immediately prior to the effective time, by the exchange ratio and rounding that result down to the nearest whole number of shares of the Company’s common stock. The per share exercise price of the converted Legacy Carisma option will be determined by dividing the per share exercise price of the
    17


    Legacy Carisma option, as in effect prior to the effective time, by the exchange ratio and rounding that result up to the nearest whole cent. As of immediately following the effective time of the Merger, 3,424,522 Legacy Carisma stock options were issued and outstanding under the 2017 Plan to purchase shares of Legacy Carisma common stock at a weighted average exercise price of $1.23 per share.

    2017 Plan Administration

    Pursuant to the terms of the 2017 Plan, the board of directors (or a committee delegated by the board of directors) administers the 2017 Plan.

    Transferability of Awards

    The 2017 Plan prohibits awards from being sold, assigned, transferred, pledged, hypothecated or otherwise encumbered by the person to whom such awards are granted, either voluntarily or by operation of law, and, during the life of a participant in the 2017 Plan, awards are exercisable only by the participant, except that certain awards may be transferred to family members through gifts or domestic relations orders or to an executor or guardian upon the death or disability of the participant. The Company is not required to recognize any such permitted transfer until such time as a permitted transferee delivers to the Company a written instrument, as a condition to such transfer, in form and substance satisfactory to the Company confirming that such transferee shall be bound by all of the terms and conditions of the applicable award.

    Effect of Certain Changes in Capitalization

    Upon the occurrence of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of common stock other than an ordinary cash dividend, under the terms of the 2017 Plan, the Company is required to equitably adjust (or make substitute awards, if applicable), in the manner determined by the board of directors:

    •the number and class of securities available under the 2017 Plan;
    •the number and class of securities and exercise price per share of each outstanding option;
    •the share and per-share provisions and the measurement price of each outstanding stock appreciation right;
    •the number of shares subject to and the repurchase price per share subject to each outstanding award of restricted stock; and
    •the share and per-share related provisions and the purchase price, if any, of each outstanding RSU award and each outstanding other stock-based award.

    Effect of Certain Corporate Transactions

    Upon the occurrence of a merger or other reorganization event (as defined in the 2017 Plan), the board of directors may, on such terms as the board of directors determines (except to the extent specifically provided otherwise in an applicable award agreement or other agreement between the participant and the Company), take any one or more of the following actions pursuant to the 2017 Plan as to all or any (or any portion of) outstanding awards, other than awards of restricted stock:

    •provide that outstanding awards will be assumed, or substantially equivalent awards will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof);
    •upon written notice to a participant, provide that all of the participant’s unexercised and/or unvested awards will terminate immediately prior to the consummation of the reorganization event unless exercised by the participant (to the extent then exercisable) within a specified period following the date of the notice;
    •provide that outstanding awards will become exercisable, realizable or deliverable, or restrictions applicable to an award will lapse, in whole or in part, prior to or upon such reorganization event;
    •in the event of a reorganization event pursuant to which holders of shares of common stock will receive a cash payment for each share surrendered in the reorganization event, make or provide for a cash payment to participants with respect to each award held by a participant equal to (1) the number of shares of common stock subject to the vested portion of the award (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such reorganization event) multiplied by (2) the excess, if any, (A) of
    18


    the cash payment for each share of common stock surrendered in the reorganization event, over (B) the exercise, measurement or purchase price of such award and any applicable tax withholdings, in exchange for the termination of such award; and/or
    •provide that, in connection with the company’s liquidation or dissolution, awards will convert into the right to receive liquidation proceeds (if applicable, net of the exercise, measurement or purchase price thereof and any applicable tax withholdings).

    The board of directors is not obligated under the 2017 Plan to treat all awards, all awards held by a participant, or all awards of the same type, identically.

    Upon the occurrence of a reorganization event other than the Company’s liquidation or dissolution, the Company’s repurchase and other rights with respect to outstanding awards of restricted stock will continue for the benefit of the succeeding company and will, unless the board of directors determines otherwise, apply to the cash, securities, or other property which the common stock was converted into or exchanged for pursuant to the reorganization event in the same manner and to the same extent as they applied to the shares of common stock subject to the restricted stock award. However, the board of directors may provide for the termination or deemed satisfaction of such repurchase or other rights under the restricted stock award agreement or in any other agreement between a participant and the Company, either initially or by amendment, or provide for forfeiture of such restricted stock if issued at no cost. Upon the Company’s liquidation or dissolution, except to the extent specifically provided to the contrary in the restricted stock award agreement or any other agreement between the participant and the Company, all restrictions and conditions on all restricted stock awards then outstanding will automatically be deemed terminated or satisfied.

    Notwithstanding the provisions of the 2017 Plan described above related to reorganization events, except to the extent specifically provided to the contrary in the applicable award agreement or in any other agreement between a participant and the Company:

    •each stock option granted under the 2017 Plan will be immediately exercisable in full if, on or prior to the first anniversary of the date of the consummation of the change in control event (as defined in the 2017 Plan), the participant’s employment with the Company or the acquiring or succeeding corporation is terminated for good reason (as defined in the 2017 Plan) by the participant or is terminated without cause (as defined in the 2017 Plan) by the Company or the acquiring or succeeding corporation; and

    •each award of restricted stock or RSUs will immediately become free from all conditions or restrictions if, on or prior to the first anniversary of the date of the consummation of the change in control event, the participant’s employment with the Company or the acquiring or succeeding corporation is terminated for good reason by the participant or is terminated without cause by the Company or the acquiring or succeeding corporation.

    The board of directors may specify in an award agreement at the time of the grant the effect of a change in control event on any stock appreciation right or other stock-based award.

    Acceleration

    At any time, the board of directors may provide that any award under the 2017 Plan will become immediately exercisable in whole or in part, free of some or all restrictions or conditions, or otherwise realizable in whole or in part, as the case may be.

    Amendment of Plan and Awards

    The board of directors may amend, suspend, or terminate the 2017 Plan or any portion thereof at any time, however if approval of the stockholders as to any modification or amendment is required under the Code, with respect to incentive stock options, the board of directors may not effect such modification or amendment without such approval. The board of directors may amend, modify or terminate any outstanding award, however the participant’s consent to such action is required unless the board of directors determines that the action, taking into account any related action, does not materially and adversely affect the participant’s rights under the 2017 Plan or the change is otherwise permitted by the 2017 Plan. Furthermore, the board of directors may amend any outstanding award granted under the 2017 Plan to provide an exercise price per share that is lower than the then-current exercise price
    19


    per share of such award or, without stockholder approval, cancel any outstanding award and grant in substitution therefor new awards under the 2017 Plan covering the same or a different number of shares of common stock and having an exercise price per share lower than the then-current exercise price per share of the cancelled award.

    Termination

    The 2017 Plan terminates on or after the date that is ten years following the earlier of (i) the date on which the 2017 Plan was adopted by the board of directors or (ii) the date the 2017 Plan was approved by the Carisma stockholders, but all awards previously granted may extend beyond such date.

    We do not expect to grant any new awards under the 2017 Plan.

    401(k) Plan

    We maintain a defined contribution employee retirement plan for our employees, including our executive officers. The plan is intended to qualify as a tax-qualified 401(k) plan so that contributions to the 401(k) plan, and income earned on such contributions, are not taxable to participants until withdrawn or distributed from the 401(k) plan (except in the case of contributions under the 401(k) plan designated as Roth contributions). Under the 401(k) plan, each employee is fully vested in his or her deferred salary contributions and our discretionary match. Employee contributions are held and invested by the plan’s trustee as directed by participants. The 401(k) plan provides us with the discretion to match employee contributions. Effective May 1, 2022, we implemented a matching policy under which we match 100% of an employee’s contributions to the 401(k) plan, up to a maximum of 5% of the employee’s base salary and bonus paid during the year.

    Policies and Practices Related to the Grant of Equity Awards

    We grant stock options to our employees and directors on an annual basis. We may also grant stock options to individuals upon hire or promotion or for retention purposes. We currently do not grant stock appreciation rights or similar option-like instruments. During the last fiscal year, neither our board of directors nor the compensation committee took material nonpublic information into account when determining the timing or terms of stock options, nor did the Company time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

    Summary of Dodd-Frank Compensation Recovery Policy or “Clawback” Policy

    We adopted the Dodd-Frank Compensation Recovery Policy (the “Clawback Policy”), effective October 2, 2023. The Clawback Policy complies with Nasdaq and SEC rules and regulations and generally provides for the recovery of erroneously awarded compensation (as defined in the Clawback Policy) received by current and former executive officers (as defined in Rule 16a-1(f) under the Exchange Act) in the event of a required accounting restatement.

    Director Compensation and Narrative Disclosure

    In April 2023, following the closing of the Merger, we adopted a director compensation policy. Under our director compensation policy, we pay our non-employee directors a cash retainer for service on our board of directors and for service on each committee on which the director is a member, and the chair of the board and of each committee receive additional retainers for such service. These fees are payable in arrears in four equal quarterly installments on the last day of each quarter, provided that the amount of such payment is prorated for any portion of such quarter that the director is not serving on our board of directors or on such committee. The fees paid to non-employee directors for service on the board of directors and for service on each committee of the board of directors on which the director is a member are as follows:


    NameMember Annual FeeChair Incremental Annual Fee
    Board of Directors$40,000$67,500
    Audit Committee$7,500$7,500
    20


    Compensation Committee$5,000$5,000
    Nominating and Corporate Governance Committee$4,000$4,000
    Science Committee$5,000$5,000

    Our director compensation policy provides that we will reimburse our non-employee directors for reasonable out-of-pocket business expenses incurred in connection with attending meetings of our board of directors and any committee of our board of directors on which they serve. Non-employee directors will also be reimbursed for reasonable out of-of-pocket business expenses authorized by the board of directors or a committee of the board of directors that are incurred in connection with attendance at various conferences or meetings with our management.

    In addition, each non-employee director has received, upon his or her initial election or appointment to our board of directors, an option to purchase 38,700 shares of our common stock under the 2014 Plan (the “Initial Option”). Each of these Initial Options will vest as to 2.7778% of the shares of our common stock underlying such option at the end of each successive one-month period following the date of grant until the third anniversary of the date of grant, subject to the non-employee director’s continued service as a director. Further, on the date of the first board meeting held after each annual meeting of stockholders, each non-employee director received an option to purchase 19,350 shares of our common stock under the 2014 Plan (the “Annual Option”). Each of these Annual Options will vest with respect to all of the shares underlying such option on the first anniversary of the grant date or, if earlier, immediately prior to the first annual meeting of stockholders occurring after the grant date, subject to the non-employee director’s continued service as a director. All options issued to our non-employee directors under the director compensation policy will be issued at exercise prices equal to the fair market value of our common stock on the date of grant and will become exercisable in full upon specified change in control events.

    Effective January 1, 2025, the board of directors approved the following modifications to the director compensation policy: (i) the Initial Option award was increased to 60,000 shares of common stock and (ii) the Annual Option award was increased to 30,000 shares of common stock.

    Item 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

    Security Ownership of Certain Beneficial Owners and Management

    Unless otherwise provided below, the following table sets forth information with respect to the beneficial ownership of our common stock as of March 31, 2025 by:

    •each of our directors;
    •each of our NEOs;
    •all of our directors and executive officers as a group; and
    •each person, or group of affiliated persons, who is known to us to be the beneficial owner of 5% or more of the outstanding shares of our common stock.

    The column entitled “Percentage of Shares Beneficially Owned” is based on a total of 41,788,096 shares of our common stock outstanding as of March 31, 2025.

    Item 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

    Certain Relationships and Related Transactions

    Related Person Transactions

    The following is a description of transactions since January 1, 2023 to which we have been a party, and in which any of our directors, executive officers and holders of more than 5% of our voting securities and affiliates of our directors, executive officers and holders of more than 5% of our voting securities, had or will have a direct or indirect material interest. We believe that all of the transactions described below were made on terms no less favorable to us than could have been obtained from unaffiliated third parties.

    Private Placement of Securities Carisma Pre-Closing Financing

    Immediately prior to the effective time of the Merger on March 7, 2023, Legacy Carisma issued an aggregate of 1,964,101 shares of Legacy Carisma common stock at a price per share of $15.60 in cash, for an aggregate purchase price of approximately $30.6 million (the “pre-closing financing”), pursuant to an Amended and Restated Subscription Agreement, dated as of December 29, 2022 (the “Subscription Agreement”), between Legacy Carisma and certain investors named therein. All of the shares of Legacy Carisma common stock issued in the pre-closing financing were exchanged into shares of our common stock at the effective time of the Merger.

    The following table sets forth the aggregate number of shares of the Legacy Carisma common stock that were issued and sold to our directors, executive officers and holders of more than 5% of our voting securities and their affiliates in the pre-closing financing and the aggregate amount of consideration for such shares:

    Indemnification Agreements

    Our Restated Certificate of Incorporation limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the Delaware General Corporation Law, and provides that no director will have personal liability to us or to our stockholders for monetary damages for breaches of fiduciary duty as a director. In addition, we have entered into indemnification agreements with each of our directors and executive officers. Each indemnification agreement provides for indemnification and advancements by the Company of certain expenses and costs relating to claims, suits or proceedings arising from each individual’s service to the Company as an officer and/or director, as applicable, to the maximum extent permitted by applicable law.

    Policies and Procedures for Related Person Transactions Our board of directors has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which our company is a participant, the amount involved exceeds $120,000 and one of our executive officers, directors, director nominees or 5% stockholders, or their immediate family members, each of whom we refer to as a “related person,” has a direct or indirect material interest.

    If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a “related person transaction,” the related person must report the proposed related person transaction to our principal financial officer or general counsel. The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by our audit committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the audit committee will review, and, in its discretion, may ratify the related person transaction. The policy also permits the chair of the audit committee to review and, if deemed appropriate, determine whether to approve proposed related person transactions that arise between committee meetings, subject to ratification by the committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.

    26


    A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the audit committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the audit committee will review and consider:

    •the related person’s interest in the related person transaction;
    •the approximate dollar value of the amount involved in the related person transaction;
    •the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;
    •whether the transaction was undertaken in the ordinary course of our business;
    •whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;
    •the purpose of, and the potential benefits to us of, the transaction; and
    •any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.
    Our audit committee may approve or ratify the transaction only if it determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. Our audit committee may impose any conditions on the related person transaction that it deems appropriate.

    In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, our board of directors has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:

    •interests arising solely from the related person’s position as an executive officer of another entity, whether or not the person is also a director of the entity, that is a participant in the transaction where the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, the related person and such person’s immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction and the amount involved in the transaction is less than the greater of $200,000 or 5% of the annual gross revenues of the Company receiving payment under the transaction; and

    •a transaction that is specifically contemplated by provisions of our certificate of incorporation or bylaws.
    The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by our compensation committee in the manner specified in the compensation committee’s charter.

    Board Determination of Independence

    Applicable Nasdaq rules require a majority of a listed company’s board of directors to be comprised of independent directors within one year of listing. In addition, Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act, and compensation committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, among other things, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board of directors must consider, for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (i) the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director; and (ii) whether the director is affiliated with the Company or any of its subsidiaries or affiliates.

    27


    Our board of directors has determined that each of our directors, with the exception of Mr. Kelly, is an “independent director” as defined under applicable Nasdaq rules, including, in the case of all the members of our audit committee, the independence criteria set forth in Rule 10A-3 under the Exchange Act, and in the case of all the members of our compensation committee, the independence criteria set forth in Rule 10C-1 under the Exchange Act. Our board of directors had determined that Chidozie Ugwumba, who resigned from our board of directors in April 2024, Regina Hodits and Björn Odlander, who resigned from our board of directors in June 2024, and Michael Torok, who resigned from our board of directors in October 2024, were each an “independent director” as defined under the applicable Nasdaq rules. In making such determinations, our board of directors considered the relationships that each such non-employee director has with our company and all other facts and circumstances that our board of directors deemed relevant in determining his or her independence, including the beneficial ownership of our capital stock by each non-employee director. Mr. Kelly is not an independent director under these rules because he serves as our President and Chief Executive Officer.

    There are no family relationships among any of our directors or executive officers.

    Item 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES

    Audit Fees and Services

    KPMG LLP was our independent registered public accounting firm for the years ended December 31, 2024 and December 31, 2023. As disclosed in a Current Report on Form 8-K filed with the SEC on March 8, 2023, on March 6, 2023, the audit committee dismissed Ernst & Young LLP as our independent registered public accounting firm, effective as of the effective time of the Merger and on March 7, 2023, the audit committee approved the engagement of KPMG LLP as our independent registered public accounting firm for the year ended December 31, 2023.

    (2)“Tax fees” for services performed in fiscal years 2023 consist of fees for tax compliance services relating primarily to the preparation of Sesen Bio’s U.S. and various state tax returns. In addition, “tax fees” for fiscal years 2023 relate to services rendered related to our recovery of German VAT taxes paid for the
    28


    shipment of our drug substance from the United States to our contract manufacturer in Germany, and tax advisory transfer pricing services.

    The reports of Ernst & Young LLP on Sesen Bio’s condensed financial statements for the interim period from January 1, 2023 through March 7, 2023 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

    In connection with the audits of Sesen Bio’s condensed financial statements for the interim period from January 1, 2023 through March 7, 2023, there were no: (i) disagreements between the Company and Ernst & Young LLP on any matters of accounting principles or practices, financial statement disclosure, or auditing scope and procedures, which disagreements if not resolved to the satisfaction of Ernst & Young LLP, would have caused Ernst & Young LLP to make reference to the matter in its report or (ii) reportable events as that term is described in Item 304(a)(1)(v) of Regulation S-K.

    During the years ended December 31, 2024 and 2023, neither us, Legacy Carisma, nor anyone on our or Legacy Carisma’s behalf, consulted with KPMG LLP, regarding either (i) the application of accounting principles to a specific transaction, completed or proposed, or the type of audit opinion that might be rendered on Legacy Carisma’s financial statements, and neither a written report nor oral advice was provided to Legacy Carisma that KPMG LLP concluded was an important factor considered by Legacy Carisma in reaching a decision as to any accounting, auditing or financial reporting issue or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).

    Audit Committee Pre-Approval Policy and Procedures

    Our audit committee has adopted policies and procedures relating to the approval of all audit and non-audit services that are to be performed by our independent registered public accounting firm. This policy provides that we will not engage our independent registered public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by our audit committee or the engagement to render the service is entered into pursuant to the audit committee’s pre-approval procedure described below.

    From time to time, our audit committee may pre-approve specified types of services that are expected to be provided to us by our independent registered public accounting firm during the next 12 months. At the time such pre-approval is granted, the audit committee must identify the particular pre-approved services in a sufficient level of detail so that our management will not be called upon to make a judgment as to whether a proposed service fits within the pre-approved services and, at each regularly scheduled meeting of the audit committee following such pre-approval, management or the independent registered public accounting firm shall report to the audit committee regarding each service actually provided to us pursuant to such pre-approval.
