  37. Non-Employee Director Compensation Policy

    Cash retainers are payable in arrears in four equal quarterly installments, provided that the amount of such payment is prorated for any portion of such quarter that the director was not serving on the Board or the relevant committee thereof. The committee chair cash retainers are provided in lieu of committee member cash retainers. The number of shares subject to each RSU award is determined by dividing the target award value by the average closing price of a share of our common stock over a 30-day period preceding the grant date. Annual grants of RSUs vest in full on the earlier of the first anniversary of the grant date or the date of the following annual meeting of stockholders of the Company, and initial appointment RSUs vest as to one-third (1/3) on the first anniversary of the grant date with the remaining portion vesting monthly over the following 24 months. Each such grant of RSUs vests in full upon the director’s death or disability or a change in control and, in each case, vesting is generally subject to the non-employee director’s continued service through the applicable vesting date. Each non-employee director was granted 2,134 RSUs on May 22, 2025. In addition, non-employee directors are reimbursed by the Company for reasonable travel and other expenses incurred in connection with the director’s attendance at Board and committee meetings, in accordance with the Company’s policies as in effect from time to time.

  39. Non-Employee Director Compensation Policy

    Proposal 2 Advisory Vote on Executive Compensation We are seeking your vote, on a non-binding advisory basis, to approve the compensation of our named executive officers as described in the Compensation Discussion and Analysis, the compensation tables and related narrative disclosure contained in this Proxy Statement, which is commonly referred to as a “say on pay” vote. Because your “say on pay” vote is advisory, it will not be binding on the Compensation Committee or the Board. However, the Compensation Committee and the Board will review the “say on pay” voting results and take them into consideration when making future decisions regarding executive compensation. The philosophy and principal objectives of our executive compensation programs are to attract, fairly compensate, appropriately incentivize, and retain superior executive talent in a manner that aligns their long-term interests with those of our shareholders. Our executive compensation program is designed to be:

  40. Non-Employee Director Compensation Policy

    | • | Competitively Positioned: Target compensation should be competitive with that being offered to individuals in comparable roles at other companies with which we compete for talent to ensure that we attract and retain the best people to lead our success. Our Compensation Committee generally targets the median of the market for target compensation opportunities but can set compensation for executives above or below that level based on factors such as individual and Company performance, an executive’s role and responsibilities relative to executives in similar positions in the market, and an executive’s actual and potential impact on the successful execution of our strategy, among others. |

  41. Non-Employee Director Compensation Policy

    | • | Performance-Driven and Shareholder-Aligned: A meaningful portion of total compensation should be variable and linked to the achievement of specific short- and long-term performance objectives and designed to drive shareholder value creation. |

  42. Non-Employee Director Compensation Policy

    | • | Responsibly Governed: Decisions about compensation should be guided by best-practice governance standards and rigorous processes that encourage prudent decision-making. |

  43. Non-Employee Director Compensation Policy

    Consistent with this philosophy, a significant portion of the total compensation opportunity for each of our executives is based on our performance. Shareholders are urged to read the Compensation Discussion and Analysis section of this Proxy Statement, which discusses how our executive compensation program, policies and procedures support our compensation philosophy and align with shareholder expectations.

  44. 2025 Executive Compensation Highlights

    2025 Executive Compensation Highlights Our executive compensation program has three primary elements: base salary, annual cash bonuses, and long-term equity compensation. Each of these compensation elements serves a specific purpose in our compensation strategy. Base salary is an essential component to any market-competitive compensation program. Annual cash bonuses reward the achievement of short-term goals, while long-term equity compensation drives our NEOs to focus on long-term sustainable

  45. 2025 Executive Compensation Highlights

    | • | Annual cash bonuses: Based on our 2025 revenue of $605.5 million and achievement or partial achievement of nine out of ten non-financial strategic objectives, each of our named executive officers was eligible for an annual bonus equal to 200% of such named executive officer’s target bonus. However, after considering our revenue and failure to achieve certain strategic objectives in full, the Chief Executive Officer recommended, and the Compensation Committee determined, that each named executive officer (other than Mr. Ranganath) would receive a bonus of 175% of target for 2025. Mr. Ranganath’s annual bonus was capped at 100% of target pursuant to his transition agreement. For more information, please see section “2025 EXECUTIVE COMPENSATION PROGRAM IN DETAIL — Annual Bonuses” below. |

  46. 2025 Executive Compensation Highlights

    | • | Long-term equity compensation: We continued to grant long-term incentives using a mix of 50% stock options and 50% restricted stock units (“RSUs”), based on grant date fair value using a 30-day average closing price, to each of our named executive officers. We also continued working with Pearl Meyer to analyze our equity granting practices, including the potential introduction of performance-based equity, and have decided to maintain our current approach at this time. We will continue to assess our equity mix in relation to our leadership and talent retention priorities, competitive market practices, and the strategic needs of our business, and may evolve our program to include performance-based equity in future years, as appropriate. For more information, please see section “2025 EXECUTIVE COMPENSATION PROGRAM IN DETAIL — Equity Incentive Awards” below. |

  47. 2025 Executive Compensation Highlights

    | • | Using a compensation peer group that appropriately reflects our size and growth trajectory and regularly reviewing and updating such peer group; |

  48. 2025 Executive Compensation Highlights

    | • | Having an annual cash bonus program driven by a formulaic measurement of revenue, with a payout cap of 200% of target annual bonus awards, and a threshold performance level; |

  49. 2025 Executive Compensation Highlights

    | • | Granting long-term incentive awards using a mix of equity that includes full value awards (RSUs) and stock options; and |

  50. Independent Compensation Consultant

    Independent Compensation Consultant The Compensation Committee believes that independent advice is important in developing and overseeing our executive compensation program. The Compensation Committee has engaged Pearl Meyer to provide consulting services in relation to executive and director compensation decisions. Pearl Meyer reports directly to the Compensation Committee and provides services to us on such matters as needed and as directed by the Compensation Committee. These services include providing guidance on trends in Chief Executive Officer, executive, and non-employee director compensation; assisting in the development of the specific components of our executive compensation program; and conducting a competitive market assessment of our executive compensation program, including the composition of our compensation peer group. Our Compensation Committee has determined, based on its analysis and in light of all relevant factors, that the work of Pearl Meyer has not created any conflicts of interest, and that Pearl Meyer is independent pursuant to the independence standards set forth in the Nasdaq listing standards promulgated pursuant to Section 10C of the Exchange Act.

  51. Use of Peer Group and Market Data

    Use of Peer Group and Market Data 2025 Compensation Peer Group. Our Compensation Committee uses peer group and other market data as a reference point to gauge the reasonableness of our executive compensation decisions and the general competitiveness of our executive compensation program in the market and to assist it in determining the type and amount of compensation that we pay. For purposes of setting compensation levels for 2025, our Compensation Committee, working in consultation with Pearl Meyer, selected companies that generally operate in the healthcare equipment/medical device industry or the early commercial biotechnology/pharmaceutical and diagnostic industry with a comparable market capitalization (targeting companies with a market value between approximately 0.33x and 3.0x our market value) and revenue (targeting companies with revenue between approximately 0.33x and 3.0x our current/projected revenue). Based on the analysis provided by Pearl Meyer, the Compensation Committee approved the following changes for our 2025 peer group, compared to the 2024 peer group, to better align the peer group with the Company’s valuation and growth trajectory and to account for M&A activity:

  56. Annual Bonuses

    Annual Bonuses Our Compensation Committee believes that a significant portion of our named executive officers’ cash compensation should be tied to our performance. Each of our named executive officers is eligible to receive an annual bonus based on the achievement of certain financial and strategic performance goals related to revenue growth, and regulatory and business goals. Target annual bonus opportunities are initially determined and thereafter reviewed annually by our Compensation Committee based on the same factors as described above for base salary. Actual awards can range from 0% to 200% of target depending on performance.

Corcoran and Ranganath to be more competitive within our compensation peer group. The 2025 target annual bonus opportunities for our named executive officers were as follows:

  59. Annual Bonuses

    | Named Executive Officer | 2025 Target Annual Bonus Opportunity (As a Percentage of Base Salary) | | Waleed H. Hassanein, M.D. | 100% | | Gerardo Hernandez | 60% | | Tamer Khayal, M.D. | 60% | | Nicholas Corcoran | 50% | | Anil Ranganath | 50% |

  60. 2025 Performance Goals

    2025 Performance Goals Our Compensation Committee determines the performance metrics and goals for our annual bonus program in the beginning of each year based on input from management and our annual business plan. Our Compensation Committee strives to set challenging, yet achievable, performance goals that will promote the achievement of short-term business objectives that are important to our annual business plan. The performance metrics for annual bonuses include financial and strategic goals that reflect our growth strategy and purpose. In 2025, our Compensation Committee determined bonus payouts based on a formulaic measurement of revenue performance against budget and additionally considered our achievement of non-financial strategic goals when reviewing performance, as follows:

  61. 2025 Performance Goals

    | • | Threshold: In order for any bonus to be earned, we must achieve 2025 revenue of at least $464M (85% of our 2025 revenue target) and three out of five of our most important strategic goals for 2025 (i.e., our other “Impact Factor One” goals). Bonuses will be earned at 50% of target if such threshold is met. |

  62. 2025 Performance Goals

    | • | Target: Bonuses will be earned at 100% of target if our 2025 target revenue goal of $545M is achieved. |

  63. 2025 Performance Goals

    | • | Maximum Bonus: Bonuses will be earned at 200% of target if our 2025 revenue is achieved at or above $600M, which is 136% growth over our actual revenue from 2024. |

  64. 2025 Performance Goals

    | 30 | TransMedics Group, Inc. 2026 Proxy Statement |

  65. 2025 Performance Goals

    If our revenue was between the threshold and target or the target and maximum performance thresholds, the amount of the bonus earned would be determined based on linear interpolation between such thresholds. Our Compensation Committee also considers a second set of non-financial strategic goals (i.e., our “Impact Factor Two” goals) to measure the functional and individual performance of our named executive officers and determine whether any downward or upward adjustment to the bonuses earned by each of our named executive officers is appropriate. Regardless of how we performed on the Impact Factor One and Impact Factor Two goals, no bonuses would be payable for 2025 if our revenue was less than $464M. Our Compensation Committee may also consider individual performance contributions and retains the discretion to adjust bonus payouts downward or upward based on its assessment of each named executive officer’s contribution to the Company during the year, as well as the achievement of strategic goals. The specific metrics and goals that were approved by our Compensation Committee for 2025, as well as the actual achievement results, are outlined below:

  66. 2025 Performance Goals

    | 2025 Performance Metrics and Goals | | Results | | Revenue | Revenue target of $545M | $605.5M | | Impact Factor One | Initiation of a US Lung clinical program & enrolling approximately 150 OCS cases by December 31, 2025 | Not Met | | | Initiation of a US Heart clinical program and enrolling approximately 150 heart cases by December 31, 2025 | Partially Met | | | Initiation of OCS Liver NOP programs in six new US liver centers by December 31, 2025 | Met | | | Maintain positive EBITDA for all four quarters of 2025 | Met | | | Launch of NOP Connect to manage all NOP services by June 30, 2025 | Met | | Impact Factor Two | Establish OCS NOP program in two countries outside the United States by December 31, 2025 | Partially Met | | | Complete MES & Workday headcount planning modules by September 30, 2025 and develop business digital transformation roadmap by December 31, 2025 | Met | | | Complete the architectural design of the fully automated and remote-controlled OCS NextGen Tech platform and initiate key third-party developers by December 31, 2025 | Met | | | Complete the architectural design of OCS Kidney by December 31, 2025 | Met |

  67. 2025 Performance Goals

    | TransMedics Group, Inc. 2026 Proxy Statement | 31 |

  68. 2025 Performance Goals

    Our 2025 revenue of $605.5 million represents a 37% increase over 2024 revenue and exceeded the established maximum revenue performance goal of $600M. Additionally, we achieved three out of five Impact Factor One goals, and we achieved three out of four of the Impact Factor Two goals. The Compensation Committee determined that the Company partially achieved its Impact Factor One goal with respect to initiating a United States Heart clinical program and enrolling approximately 150 heart cases by December 31, 2025 and its Impact Factor Two goal of establishing an OCS NOP program in two countries outside the United States by December 31, 2025. The partial achievement of such goals was attributable to unusual and unexpected delays by FDA review of the pre-clinical testing, which delayed the approval of the IDE to initiate the clinical trials. As a result, each of our named executive officers was eligible for an annual bonus equal to up to 200% of such named executive officer’s target bonus. However, after considering our revenue and failure to meet certain Impact Factor One and Impact Factor Two goals in full, the Chief Executive Officer recommended, and the Compensation Committee determined, that each named executive officer, other than Mr. Ranganath, would receive a bonus of 175% of target for 2025. Pursuant to the terms of a Transition Agreement, dated February 3, 2026, between the Company and Mr. Ranganath (the “Ranganath Transition Agreement”), Mr. Ranganath was eligible to and did receive an annual bonus for 2025 equal to 100% of his target annual bonus. The resulting bonus payouts for our named executive officers for 2025 are set forth below:

  69. 2025 Performance Goals

    | Named Executive Officer | 2025 Annual Base Salary | 2025 Target Annual Bonus Opportunity (as a % of Salary) | 2025 Target Annual Bonus Opportunity | 2025 Actual Annual Bonus Payout (as a % of Target) | Actual Annual Bonus Payout | | Waleed H. Hassanein, M.D. | $800,000 | 100% | $800,000 | 175% | $1,400,000 | | Gerardo Hernandez | $500,000 | 60% | $300,000 | 175% | $525,000 | | Tamer Khayal, M.D. | $500,760 | 60% | $300,456 | 175% | $525,798 | | Nicholas Corcoran | $456,750 | 50% | $228,375 | 175% | $399,656 | | Anil Ranganath | $416,000 | 50% | $208,000 | 100% | $208,000 |

  70. Equity Incentive Awards

    Equity Incentive Awards Our Compensation Committee believes that in order to appropriately incentivize our named executive officers to create shareholder value, a significant portion of our named executive officers’ compensation should be in the form of equity-based compensation. Our equity-based compensation program is designed to align the interests of our executives and shareholders by promoting stock ownership by our executives and senior management, tying compensation realized to stock price performance and encouraging retention. For 2025, our Compensation Committee granted equity incentive awards using a mix of 50% stock options and 50% RSUs, calculated based on target grant date fair value using the average closing price over the 30-day period preceding the grant date.

  71. Equity Incentive Awards

    | Equity Vehicle | Weighting | Features | | Stock Options | 50% | • Stock options are intended to align the interests of award recipients with those of shareholders since stock options only deliver value if our stock price appreciates after they are granted. • Stock options generally vest on a monthly basis over four years, generally subject to the named executive officer’s continued employment with us; stock options issued to new hires generally vest 25% on the first anniversary of the grant date and the remaining shares vest in equal monthly installments over three years thereafter. | | RSUs | 50% | • RSUs are intended to support our talent retention objectives while also aligning the interests of award recipients with those of shareholders since the value of RSUs is based on the value of our stock price. • RSUs generally vest on an annual basis over three years (four years for RSUs issued to new hires), generally subject to the named executive officer’s continued employment with us. |

  72. Equity Incentive Awards

  73. Equity Incentive Awards

    Our Compensation Committee determined the target value of each named executive officer’s 2025 annual equity awards based on competitive market data, as described above, our strong performance in 2024, and each named executive officer’s past individual performance and expected future contributions. Based on the size of Mr. Hernandez’s new hire equity award and his December 2024 start date, consistent with our internal compensation practices for new leaders, Mr. Hernandez was not eligible for annual equity awards in 2025, but the Compensation Committee decided to award Mr. Hernandez an annual equity award at the same time annual long-term incentives were awarded to our other named executive officers to improve his competitive positioning relative to market and to align a portion of his long-term incentive compensation, including the exercise price of certain stock options, with that of our other named executive officers and other equity eligible employees. The total target award grant date fair values for each named executive officer for 2025, as approved by the Compensation Committee and calculated using the average closing price over the 30-day period preceding the grant date, are shown in the table below:

  74. Equity Incentive Awards

    | Named Executive Officer | Stock Options Target Grant Date Value | RSUs Target Grant Date Value | Total Target Grant Date Value | | Waleed H. Hassanein, M.D. | $4,250,000 | $4,250,000 | $8,500,000 | | Gerardo Hernandez | $250,000 | $250,000 | $500,000 | | Tamer Khayal, M.D. | $1,250,000 | $1,250,000 | $2,500,000 | | Nicholas Corcoran | $900,000 | $900,000 | $1,800,000 | | Anil Ranganath | $400,000 | $400,000 | $800,000 |

  75. Equity Incentive Awards

    The number of shares subject to each award was determined by dividing the target award values by the average closing price of our common stock over a 30-day period preceding the grant date (and, for options, a Black-Scholes ratio). Values shown in the table above may differ from the values shown in the Summary Compensation Table and the Grants of Plan-Based Awards Table.

  76. Change in Control and Severance Benefits

    Change in Control and Severance Benefits We have entered into offer letters with Mr. Hernandez, Dr. Khayal, and Mr. Corcoran that set forth the initial terms and conditions of employment, and we have entered into retention agreements with Dr. Hassanein, Mr. Hernandez, and Dr. Khayal that provide for severance payments and benefits in connection with certain terminations of employment. Mr. Corcoran’s offer letter provides for severance payments in connection with certain terminations of employment. In addition, certain of the equity awards granted to our named executive officers would vest in connection with a qualifying termination of employment following a change in control. Prior to his transition from Senior Vice President, General Counsel & Corporate Secretary of the Company to a non-executive employee of the Company, we had also been party to an offer letter and a retention agreement with Mr. Ranganath and, in connection with his transition we entered into a transition agreement with Mr. Ranganath that provides for his entitlement to certain severance payments and benefits. The severance payments and benefits for all of our named executive officers are more fully described below under “Potential Payments upon Termination or Change in Control.” Our Compensation Committee believes that reasonable severance payments and benefits are necessary to attract and retain executives and are important in incentivizing them to pursue a change in control transaction if it is in the best interests of our shareholders even if it creates uncertainty for them.

  77. Practices Related to the Grant of Certain Equity Awards

    Practices Related to the Grant of Certain Equity Awards The Company generally maintains a structured equity grant timing process designed to ensure compliance with applicable securities laws, corporate governance best practices, and the avoidance of material nonpublic information (“MNPI”) in granting equity awards. The Compensation Committee generally grants annual equity-based awards to our executive officers in February of each year, in connection with our annual compensation review and approval process, although the exact timing may change from year to year. Our Compensation Committee may also grant equity awards, including RSUs and stock options, at different times of the year for new hires and in connection with promotions, or grants made for retention or other purposes. Stock option exercise prices are set at the closing price of the Company’s common stock on the grant date, in accordance with the Company’s equity plan and applicable securities regulations. This process is designed to prevent any appearance of opportunistic grant timing and to ensure that equity awards are made in a manner that reflects long-term stockholder value creation. Our Compensation Committee does not grant equity awards in anticipation of the release of MNPI and we have not timed the disclosure of MNPI for the purpose of affecting the value of executive compensation.

We have also entered into a retention agreement with each of Dr. Hassanein and Dr. Khayal that provides for severance payments and benefits in the event the named executive officer’s employment is terminated in certain circumstances. Mr. Corcoran’s offer letter provides for severance payments and benefits in connection with certain terminations of employment. Prior to his transition from Senior Vice President, General Counsel & Corporate Secretary of the Company to a non-executive employee of the Company, we had been party to an offer letter and a retention agreement with Mr. Ranganath. In connection with his transition, we entered into the Ranganath Transition Agreement with Mr. Ranganath.

The material terms of these agreements are summarized below. As used in the summary below, the terms “cause,” “disability,” “good reason” and “change in control” have the meanings set forth in the applicable agreement. Dr. Hassanein.

If his employment terminates in such circumstances either in connection with or in anticipation of, or within 24 months following, a change in control, then, in lieu of the payments and benefits described above, Dr. Hassanein will be entitled to receive (A) an amount equal to one and one-half (1.5) times the sum of his highest annual base salary during the preceding three years and his highest annual bonus during the preceding three years, payable in a lump sum; (B) Company-provided benefits for up to 18 months; (C) an additional 18 months of service credit for purposes of eligibility for any retiree benefits; (D) accelerated vesting of all of his then-outstanding and unvested stock options, restricted stock, and other equity-based awards; and (E) any accrued but unpaid compensation and benefits, including a prorated annual bonus for the year in which his employment terminates, based on Dr. Hassanein’s annual bonus for the preceding year.

  130. CEO Pay Ratio

    CEO Pay Ratio Under SEC rules, we are required to disclose the ratio of our CEO’s annual total compensation to the median of the annual total compensation of all of our other employees. We determined that the 2025 median of the annual total compensation of all of our employees who were employed as of December 31, 2025, other than our CEO, Dr. Hassanein, was $127,304. Dr. Hassanein’s 2025 annual total compensation was $10,915,533 (as reported in our Summary Compensation Table above). Based on the foregoing, our estimate of the ratio of Dr. Hassanein’s annual total compensation to the median annual total compensation of all of our other employees was 86 to 1. As of December 31, 2025, our total population, excluding Dr. Hassanein, consisted of 897 employees located in the United States, France, Germany, Ireland, Italy and the Netherlands. Pursuant to SEC rules, we excluded all of our non-U.S. employees (1 employee located in France, 6 employees located in Germany, 1 employee located in Ireland, 21 employees located in Italy, and 1 employee located in the Netherlands) for purposes of identifying our median employee. After applying this exemption, the employee population, excluding Dr. Hassanein, used for purposes of identifying the median employee consisted of 867 employees. To identify the median employee, we used Box 5 W-2 data for all such 867 individuals (with the exception of Dr. Hassanein) employed by us on December 31, 2025, annualizing such data for those individuals employed by us for less than the full year of 2025. We then calculated the annual compensation of the median employee using the same methodology used to calculate Dr. Hassanein’s compensation for the Summary Compensation Table. We believe that the pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. The SEC rules for identifying the median employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Therefore, our ratio may not be comparable to the ratios disclosed by other companies based on a number of factors, including differences in employee populations, different geographic distributions of employees, and the nature of the companies’ businesses.

  132. Pay Versus Performance Disclosure

    Pay Versus Performance Disclosure In accordance with rules adopted by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we provide the following disclosure regarding executive “Compensation Actually Paid” (“CAP”) and certain performance measures for the fiscal years listed below. The Compensation Discussion & Analysis (“CD&A”) describes the compensation setting process for our executive officers, which is done independently from the disclosure requirements.

  133. Pay Versus Performance

    Pay Versus Performance The following table provides the information required for our NEOs for each of the fiscal years ended December 31, 2025, December 31, 2024, December 31, 2023, December 31, 2022, and December 31, 2021 along with the required financial information required for each fiscal year. CAP is calculated in accordance with SEC rules and includes the increase or decrease in value of certain elements of compensation over each fiscal year, including compensation granted in a prior year. CAP does not correlate to the total amount of cash or equity compensation paid or received during each fiscal year. The calculations do not reflect the actual sale of stock underlying equity awards or the exercise of stock options by the executive, and the amount of compensation ultimately received may, in fact, be different from the CAP amounts disclosed in the table below:
