  1. ELECTION OF DIRECTORS

    ELECTION OF DIRECTORS Our Board currently consists of nine directors. There are nine nominees for director this year, all of whom were nominated by our Board, consisting of our incumbent directors. Each director to be elected will hold office until the next annual meeting of stockholders and until his or her successor is elected, or until the director’s earlier death, resignation or removal. All nominees listed below are currently our directors and were previously elected by our stockholders at the 2024 Annual Meeting of Stockholders, except for Mr. Binder who was appointed to the Board in October 2024. It is our policy that directors are invited and expected to attend annual meetings. All of our directors attended the 2024 Annual Meeting of Stockholders. Directors are elected by a plurality of the votes properly cast at the Annual Meeting or by proxy. The nine nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nine nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares may be voted for the election of a substitute nominee proposed by our Nominating and Corporate Governance Committee. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve. We believe that we have an accomplished slate of nominees, with diversity of thought, experience, perspective and skills beneficial to the Company. All nominees except Messrs. Castagna and Binder are independent. The average tenure of our directors is approximately 9.3 years, which includes three directors with more than a dozen years of history with the Company and four directors who joined the Board after 2019. We believe that a mix of service lengths is beneficial to the overall functioning of the Board.

  9. Independence of the Board of Directors

    Independence of the Board of Directors As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. Our Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect time to time. Consistent with these considerations, after review of all relevant transactions or relationships between each director or any of his or her family members and the Company, its senior management and its independent auditors, the Board affirmatively has determined that all of the Company’s directors, other than Messrs. Castagna and Binder, are independent within the meaning of the applicable Nasdaq listing standards. Mr. Castagna was determined not to be independent under applicable Nasdaq listing standards due to his position as an executive officer of our company. Mr. Binder was similarly determined not to be independent under applicable Nasdaq listing standards due to his former position as an executive officer of the Company. In making this determination, the Board found that none of the other directors has a disqualifying relationship with the Company.

  10. Information Regarding the Board of Directors and its Committees

    Information Regarding the Board of Directors and its Committees We are committed to maintaining the highest standards of business conduct and ethics. Our Board has adopted a Code of Business Conduct and Ethics and adheres to corporate governance guidelines to assure that the Board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of our stockholders. The charters for various Board committees set forth the practices the Board will follow with respect to board composition and selection, board meetings and involvement of senior management, Chief Executive Officer performance evaluation and succession planning, and board committees and compensation. Our Board adopted these measures to, among other things, reflect changes to the Nasdaq listing standards and SEC rules adopted to implement provisions of the Sarbanes-Oxley Act of 2002, as amended. Our Code of Business Conduct and Ethics, as well as the charters for each committee of the Board, may be viewed on our website at mannkindcorp.com/corporate-governance/.

  12. Director Qualifications

    Director Qualifications The Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including being able to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also considers such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of the Company’s stockholders. However, the Nominating and Corporate Governance Committee retains the discretion to modify these qualifications from time to time.

  13. Evaluating Nominees for Director

    Evaluating Nominees for Director The Nominating and Corporate Governance Committee reviews candidates for director nominees in the context of the current composition of the Board of Directors, the operating requirements of the Company and the long-term interests of the Company’s stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee considers age, skills, and such other factors as it deems appropriate given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability. In the case of incumbent directors, the Nominating and Corporate Governance Committee reviews such directors’ overall service to the Company during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee would be independent, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee does not have a formal policy with respect to diversity; however, the Board and the Nominating and Corporate Governance Committee believe that it is important that directors represent different educational backgrounds, professional experiences, viewpoints and skills. The Nominating and Corporate Governance Committee assesses these factors in connection with the annual nomination process as well as in new director searches. The Nominating and Corporate Governance Committee uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider such candidates’ qualifications and then selects one or more nominees for recommendation to the Board by majority vote. To date, the Nominating and Corporate Governance Committee has not paid a fee to any third party to assist in the process of identifying or evaluating director candidates.

  14. COMPENSATION OF DIRECTORS

    COMPENSATION OF DIRECTORS Pursuant to our non-employee director compensation program (the “director compensation program”), as amended in August 2024, each of our non-employee directors receives an annual retainer and fees for their service on our standing board committees as follows:

  15. COMPENSATION OF DIRECTORS

    | Element | Amount | | Annual Retainer | $50,000 | | Independent Chair Premium | $50,000 | | Audit Committee | Chair: $25,000 | | | Other members: $10,000 | | Compensation Committee | Chair: $20,000 | | | Other members: $7,500 | | Nominating and Corporate Governance Committee | Chair: $10,000 | | | Other members: $5,000 |

  16. COMPENSATION OF DIRECTORS

    The members of the Board are also eligible for reimbursement for their expenses incurred in attending Board meetings in accordance with Company policy. Other than the annual fees described above, our non-employee directors do not receive meeting fees or other compensation for their attendance at specific Board or committee meetings. Our director compensation program specifies that each non-employee director of the Company is also eligible to receive annual equity awards under our 2018 Equity Incentive Plan (the "EIP"). Specifically, on the date of each of our annual stockholder meetings, each of our non-employee directors receives a restricted stock unit ("RSU") award determined by dividing $250,000 by the then-current stock price used for valuing employee equity awards, which in no event is less than the last reported closing price of the Company’s common stock. Each such annual RSU award vests immediately, but shares are not distributed until the director separates from service to the Board (i.e. retires, is removed or dies). A non-employee director who joins the Board between annual stockholders meetings is entitled to a pro-rata compensation package. Non-employee directors have an option to receive their annual $50,000 retainer in cash or common stock of the Company. If a non-employee director elects to receive his or her annual retainer in common stock, such director will be granted an RSU award consisting of that number of shares that equals 100% of the annual retainer, based on the 20-day trailing average closing price as of the trading day immediately preceding the date of the annual stockholder meeting. This award vests immediately, but shares are not distributed until the director separates from service to the Board (i.e. retires, is removed or dies). Non-employee directors who do not elect this option receive the full annual retainer in cash shortly after the date of the stockholder meeting.

  17. Director Compensation Table

    Director Compensation Table The following table sets forth information concerning director compensation received for the fiscal year ended December 31, 2024 by our non-employee directors, other than Mr. Binder whose compensation is set forth in our 2024 Summary Compensation Table:

  20. Compensation Philosophy and Objectives

    Compensation Philosophy and Objectives The Compensation Committee oversees our executive compensation within the context of a compensation philosophy. This philosophy is to provide compensation and benefits programs designed to attract, engage, and retain a high caliber workforce that enables us to compete with companies in the pharmaceutical and biotechnology industries and to reward individual and corporate performance. We believe that a well-designed compensation program for our executive officers should: • align the goals of the executive officer with the goals of our stockholders; • recognize individual initiative and achievement; • provide total compensation that enables us to compete with companies in the pharmaceutical and biotechnology industries; and • align compensation with our short-term and long-term corporate objectives and strategy, focusing executive officer behavior on the fulfillment of those objectives. In keeping with this philosophy, our executive compensation program is designed to achieve the following objectives: • attract talented and experienced executives; • motivate and reward executives whose knowledge, skills and performance are critical to our success; • retain executives and employees who are instrumental in accomplishing our corporate goals; • align the interests of our executives and stockholders by motivating executives to increase stockholder value and rewarding executives when stockholder value increases; • provide a competitive compensation package which is weighted towards pay-for-performance (including, when appropriate, long-term incentives such as performance equity awards), and in which total compensation is primarily determined by the Company’s and the individual’s achievement of results; • ensure fairness among the executive management team by recognizing the contributions each executive makes to our success; • foster a shared commitment among executives by aligning the Company’s and their individual goals; and • compensate our executives to manage our business to meet our long-term objectives.

  21. Competitive Market Assessment

    Competitive Market Assessment No less frequently than annually, the Compensation Committee reviews competitive market data to determine if our compensation levels remain at targeted levels and our pay practices are appropriate. These assessments include a review of base salary, STI compensation, and long-term incentive ("LTI") compensation. These components are benchmarked against a group of peer companies. Our peer group of similarly situated companies was developed by considering U.S.-based companies in the same industry (biotechnology/pharmaceutical) with similar company characteristics, such as revenue, market capitalization, and number of employees. In addition to these criteria, we consider companies with a similar competitive strategy, including utilizing an internal sales force, and maintaining internal manufacturing capabilities. In order to ensure that we do not exclude potential peers, we also take note of companies considered to be our peers by Institutional Shareholder Services for their benchmarking purposes. We review the list annually to ensure that our peer group is relevant while also striving for year-over-year consistency. In accordance with our annual process, the Compensation Committee reviewed our peer group in the first quarter of 2024. Based on data compiled by Mercer and reviewed by the Compensation Committee during this process, the Compensation Committee determined that two companies needed to be removed from the list: Sangamo Therapeutics, Inc., who does not have a product on the market and does not employ a sales force and Agenus Inc., whose market value is outside our peer screening criteria and who also does not have a product on the market and does not employ a sales force. In place of these companies, the Compensation Committee added two companies that satisfied our criteria for peer companies: Ironwood Pharmaceuticals, Inc. and Mirum Pharmaceuticals, Inc. Accordingly, the full 2024 peer group consisted of the following 12 companies:

  22. Competitive Market Assessment

    | ADMA Biologics, Inc. (ADMA) | Ironwood Pharmaceuticals, Inc. (IRWD) | | Anika Therapeutics, Inc. (ANIK) | Karyopharm Therapeutics Inc. (KPTI) | | BioCryst Pharmaceuticals, Inc. (BCRX) | Macrogenics Inc. (MGNX) | | Deciphera Pharmaceuticals, Inc. (DCPH) | Mirum Pharmaceuticals, Inc. (MIRM) | | Dynavax Technologies Corporation (DVAX) | Rigel Pharmaceuticals Inc. (RIGL) | | Insmed Inc. (INSM) | Vanda Pharmaceuticals Inc. (VNDA) |

  23. Competitive Market Assessment

    For some executive positions, the peer group data may not be sufficiently robust, or the position may not have an appropriate counterpart at our peer companies. In those cases, we will also consider industry specific and general published survey compensation data, such as the Aon Radford McLagan Global Life Sciences Executive Survey.

  24. Market Positioning

    Market Positioning The Compensation Committee reviews executive compensation at least annually, establishes competitive compensation levels and designs the compensation program to provide pay commensurate with individual and corporate performance. With support from Mercer, we have targeted total compensation levels for executives at the median of our peer group. We believe this target to be an appropriate level of compensation to attract and retain qualified and capable executives. However, actual compensation (or individual elements of compensation) may fall above or below this level under a range of circumstances, such as individual and Company performance, tenure with the Company or retention concerns. In addition to the factors listed above, we also consider, among other things: • our business need for the executive officer’s skills; • the contributions that the executive officer has made, or we believe will make, to our success; • the transferability of the executive officer’s managerial skills to other potential employers; and • the relevance of the executive officer’s experience to other potential employers, particularly in the pharmaceutical and biotechnology industries. As discussed in more detail below, we consider each element of executive compensation and make adjustments as appropriate. We believe our executive compensation packages are reasonable when considering our business strategy, the revenue potential of our business, our compensation philosophy and the competitive market data.

  25. Consideration of Past Say-on-Pay Results

    Aided by these insights, our annual equity award program for executives and other senior employees is designed to emphasize performance-based vesting, measured over a multi-year period. This component of long-term compensation pays out, if at all, in proportion to the Company’s total stockholder return relative to the Russell 3000 Pharmaceutical and Biotechnology industry index over a multi-year period. We believe that this approach to long-term compensation is responsive to investors’ preference for performance-vesting long-term compensation while also providing compensation that attracts, motivates, incentivizes and retains highly qualified executive officers to drive the success of the Company.

  26. Base Salary

    Base Salary Base salaries are designed to provide compensation for the day-to-day management of the Company, assuming satisfactory levels of performance. This component is designed to provide consistent and steady cash flow for the executive and represents only a portion of total compensation. Salary levels are based primarily upon the competitive market for the executive officers’ services, as reflected by the peer group. Base salaries for our executives are generally intended to fall within 10% of the median of the competitive market, although individual performance, responsibility, and the importance of each role in our organization can also impact base salary levels. In 2024, the Compensation Committee reviewed executive salaries and other elements of compensation against the benchmarks provided by our peer group. The base salaries of all executives were found to be consistent with the competitive market (inclusive of a 3% cost of living increase in base salaries from 2023 to 2024).

  27. Short-Term Incentive Plan

    Short-Term Incentive Plan Each of our executive officers is eligible to receive an annual performance-based cash payment. The annual cash incentive awards under our STI plan are intended to compensate our executive officers for achieving our annual goals at the corporate level and for achieving individual annual performance objectives. The objectives for our company and individual measures are established so that performance at or above target levels requires significant effort on the part of our executives. The STI plan is funded based on the overall achievement of corporate objectives, as determined by the Compensation Committee in its evaluation of the accomplishments of the Company during the previous year. Evaluation criteria can be quantitative or qualitative, depending on the objective. Quantitative objectives are typically evaluated using a leverage curve that allows up to a 200% payout for over-achievement of up to 120% of the stated target and imposes on a 0% payout for any achievement that falls below 80% of the stated target. The STI plan is an important part of our pay-for-performance culture. We believe that tying a significant portion of our executive cash compensation to financial and operational goals – such as production goals, revenue metrics and progress of product development milestones – encourages corporate performance and stock price growth. This element of compensation is truly at risk, as reflected in the table below that shows the various achievement level of the corporate objectives over the last few years:

  28. Short-Term Incentive Plan

    | Year Achieved (paid in the following year) | STI Achievement Level | | 2017 | 90% | | 2018 | 50% | | 2019 | 93% | | 2020 | 125% | | 2021 | 115% | | 2022 | 124% | | 2023 | 144% | | 2024 | 125% |

  29. Short-Term Incentive Plan

    Early in 2024, the Board of Directors specified three main corporate objectives for 2024. In January 2025, the Compensation Committee evaluated the performance of the Company against the corporate objectives as follows:

  30. Short-Term Incentive Plan

    | Objective | Target | Assessment | Result | | Deliver on Tyvaso DPI production | 30% | Assessed quantitatively with respect to production goals and qualitatively with respect to actions taken to expand production | 57.5% | | Drive endocrinology business | 30% | Assessed quantitatively with respect to financial metrics and qualitatively with respect to clinical development milestones | 35.0% | | Advance pipeline opportunities | 30% | Assessed quantitatively with respect to the achievement of development milestones | 21.5% | | Finance/Quality | 10% | Assessed qualitatively | 11.0% | | Overall Result | | | 125.0% |

  31. Short-Term Incentive Plan

    Each eligible position, including the executive officers, is assigned a target STI opportunity expressed as a percentage of base salary, which reflects market competitive levels. Target STI opportunities are generally intended to be at the 50th percentile of the market. For Mr. Castagna, the target STI opportunity is 80% of base salary. For all other executive officers, the target STI opportunity is 50% of base salary. As a result of the Compensation Committee’s determination that the Company as a whole achieved 125.0% of its 2024 corporate goals, 125.0% of the aggregate target STI opportunity for all executive officers was made available for cash incentive awards to be paid in April 2025.

  32. Long-Term Incentives

    Long-Term Incentives In order to provide a significant retention incentive and to ensure a strong link to the long-term interests of stockholders, we provide a portion of our total compensation in the form of LTI compensation, which is generally delivered as an equity award (typically restricted stock units). In 2024, all employees, including executive officers, were eligible to receive equity awards. Equity awards are granted under the 2018 Equity Incentive Plan, which is administered by the Compensation Committee pursuant to a delegation of concurrent authority by our Board of Directors. The awards are made at the discretion of the Compensation Committee, after taking into consideration grant guidelines that we have developed. In 2024, based on the benchmarks provided by our peer group, the Compensation Committee determined that our equity guidelines for executive officers had fallen below the median of our peer group. Accordingly, the annual long-term incentive awards for executive officers were revised to target $4.5 million (from 450% of base salary target used in the prior year) for the CEO and $1.25 million (an increase from the 200% of median base salary target used in the prior year) for all other executive officers. These revised targets correspond to approximately the 60th percentile of the competitive market, but they can be modified at the discretion of the Compensation Committee for a range of reasons, including but not limited to, company performance, individual employee performance, financial position of the company, number of shares available for grant under the equity incentive plan, the volatility of the stock price, and similar factors. Our policy with regard to the timing of grants of equity compensation is to issue annual grants of equity awards in connection with a regularly scheduled quarterly meeting of the Compensation Committee. The timing of grant dates is not based on any favorable or unfavorable non-public information anticipated to be disclosed at a later date. All stock option awards are granted with an exercise price equal to the closing price of our common stock on the Nasdaq Global Market on the date of the meeting at which such stock options were granted. In May 2024, annual equity awards were delivered as grants of both performance-based and time-based restricted stock units. The total target amount of annual equity compensation (i.e., $4.5 million for the CEO; $1.25 million for each of the other executive officers) was converted into a number of shares using the then-current 20-day trailing average stock price and the resulting number was divided into two awards of restricted stock units. For clarity, the values of these grants for purposes of the Summary Compensation Table on page 34 and the Grants of Plan table on page 36 are calculated on the basis of a Monte Carlo simulation of the grant date fair market value.

  33. Long-Term Incentives

    | Executive Officer | LTI Guideline | Performance-based Award | Time-based Award | | Mr. Castagna | 1,034,000 shares | 569,000 RSUs | 465,000 RSUs | | Messrs. Blank, Prentiss, Singh, Thomson, Tross and Ms. Sabella | 287,000 shares | 158,000 RSUs | 129,000 RSUs | | Mr. Binder (1) | 287,000 shares | 0 RSUs | 287,000 RSUs |

  34. Long-Term Incentives

    | (1) Mr. Binder did not receive any performance-based restricted stock unit awards during the year ended December 31, 2024. Prior to the grant date, Mr. Binder had transitioned out of the role of Chief Financial Officer and announced his intention to retire later in 2024. |

  35. Long-Term Incentives

    One award, representing approximately 45% of total annual equity incentive, was delivered as a time-based restricted stock unit that vests 25% annually, commencing in July 2025 and ending in July 2028. The other award, representing approximately 55% of the total annual equity incentive, was delivered as a performance stock unit that cliff-vests in July 2027. The number of shares delivered on the vesting date, as a percentage of the target number specified in the table above, will be determined by the percentile ranking of the Company’s total stockholder return (“TSR”) over a three-year measurement period from July 2024 until June 2027 relative to the TSR of the Russell 3000 Pharmaceutical & Biotechnology Index over the same period, as follows: • <25th percentile = 0% of target • 25th percentile = 50% of target • 50th percentile = 100% of target • 75th percentile = 200% of target • ≥90th percentile = 300% of target Payout values will be interpolated between the percentile rankings above. As reflected in the Summary Compensation Table on page 34, executive officers who were awarded a performance-based stock unit in 2021 received a payout from such awards in May 2024. Based on the relative performance of the Company’s TSR over the measurement period (198%), each such executive officer received a number of shares that corresponded to 198% of target for such awards. We believe that the use of relative TSR is an appropriate metric for LTI compensation whereas operational metrics, such as revenue growth, are better suited for STI. Putting a majority of the LTI at risk and tying the value of that compensation to stockholder returns over the same period aligns with our pay-for performance philosophy. At the same time, the inclusion of time-based awards within the LTI program encourages employee retention and fosters equity ownership, which are additional objectives of our compensation program.

  36. Severance Provisions

    Severance Provisions Currently, we have no severance agreements with our executive officers, except with Mr. Thomson. The terms of the agreement and amounts that may be realized are detailed under the heading “Potential Payments Upon Termination or Change of Control.”

  37. Change of Control Provisions

    Change of Control Provisions We have entered into change of control agreements with each of our executive officers in order to ensure that we have the continued dedication of these executives and in order to provide them with reasonable compensation and benefit arrangements in the event of termination of their employment following a change of control. We believe that it is imperative to diminish any distraction of our executives arising from the personal uncertainty and insecurity that arises in the absence of any assurance of job security, thereby allowing executives to focus on corporate objectives and strategy. The terms of these agreements and amounts that may be realized are detailed under the heading “Potential Payments Upon Termination or Change of Control.”

  38. Summary Compensation Table

    Summary Compensation Table The following table shows for the three year period ended December 31, 2024 compensation awarded to, or earned by: • the individuals who served as our principal executive officer ("PEO") or principal financial officer for any portion of 2024; • our three most highly compensated executive officers in 2024, other than the individuals listed above, who were serving as executive officers during 2024 and as of December 31, 2024.

  40. Summary Compensation Table

    | (1) Includes amounts earned but deferred at the election of the named executive officer, such as salary deferrals under our 401(k) Plan established under Section 401(k) of the Code. | | (2) Represents the aggregate grant date fair value of the restricted stock unit awards comprised of time-based and performance-based stock awards. Time-based restricted stock unit awards are valued based on the market price of the stock on the grant date. Performance-based restricted stock unit awards are valued based on a Monte-Carlo simulation model. Those issued during the year ended December 31, 2024 had a grant date fair value of $10.30 per share and will vest on July 15, 2027. The fair value of the performance-based restricted stock unit awards was determined using a share price of $4.45, risk-free interest rate of 4.46%, volatility of 61%, and a dividend yield of 0%. The number of shares delivered on the vesting date is determined by the percentile ranking of TSR over the period from July 1, 2024 until June 30, 2027 relative to the TSR of the Russell 3000 Pharmaceutical & Biotechnology Index over the same period, as follows: less than 25th percentile=0% of target, 25th percentile=50% of target, 50th percentile=100% of target, 75th percentile=200% of target, 90th percentile or higher=300% maximum. Payout values will be interpolated between these percentile rankings. The 300% maximum yields the following: Mr. Castagna, $7,596,150; Mr. Prentiss, $2,109,300; Dr. Blank, $2,109,300; Ms. Sabella, $2,109,300 and Mr. Thomson, $2,109,300. Mr. Binder did not receive any performance-based restricted stock unit awards during the year ended December 31, 2024. | | (3) Represents non-equity incentive plan compensation earned in the applicable year which is paid (or will be paid) in the following year. Non-equity incentive plan compensation is based on individual performance in the achievement of corporate objectives. Performance is compared to these objectives annually. | | (4) Amounts include employer contributions credited under our 401(k) Plan and the incremental cost of perquisites received by the named executive officers. Under the 401(k) Plan, which is open to substantially all of our employees, we make matching contributions based on each participant’s voluntary salary deferrals, subject to the provisions of the 401(k) Plan and limits of the Code. | | (5) Includes $11,500 in contributions under the 401(k) Plan, $14,439 in medical benefits and $1,855 in group term life insurance benefits. | | (6) On April 22, 2024, Mr. Prentiss was appointed as Chief Financial Officer. | | (7) Includes $191,609 in relocation benefits, $6,989 in contributions under the 401(k) Plan, $1,943 in medical benefits and $1,092 in group term life insurance benefits | | (8) On April 22, 2024, Mr. Binder retired as our Chief Financial Officer and was appointed as our Executive Vice President, Special Projects until he joined the Board effective September 30, 2024. | | (9) Includes $15,250 in contributions under the 401(k) Plan, $32,058 in medical benefits and $3,295 in group term life insurance benefits. Also includes $33,333 as a pro-rated cash retainer for his Board service and $118,104 which represents the grant date fair value of a restricted stock unit award that Mr. Binder received on November 18, 2024 as a pro-rated equity award made in connection with his Board appointment effective September 30, 2024. | | (10) Includes $15,250 in contributions under the 401(k) Plan, $7,664 in group term life insurance benefits and $3,250 in other stipend. | | (11) Includes $13,542 in contributions under the 401(k) Plan, $20,366 in medical benefits and $4,323 in group term life insurance benefits. | | (12) Includes $12,150 in contributions under the 401(k) Plan, $21,063 in medical benefits and $3,658 in group term life insurance benefits. |

  43. Grants of Plan-Based Awards

    | (1) Annual cash incentive awards under our STI plan are based on a percentage of base salary of 80% for Mr. Castagna and 50% for other NEOs. Actual payout of these awards is assessed by the Compensation Committee as a result of performance against defined corporate objectives. Estimates of these payouts are computed using the following percentages of meeting the corporate objectives: threshold = 0%, target = 100%, and maximum = 200%. The Compensation Committee assessed the achievement of corporate goals of 125.0% for the year ended December 31, 2024, resulting in the following amounts payable: Mr. Castagna, $766,442; Mr. Prentiss, $187,981; Mr. Binder, $247,548; Dr. Blank, $281,029; Ms. Sabella, $281,029; and Mr. Thomson, $315,988. | | (2) The restricted stock units will vest on July 15, 2027 subject to continuing service. The number of shares delivered on the vesting date is determined by the percentile ranking of the Company’s total stockholder return (TSR) over the period from July 1, 2024 until June 30, 2027 relative to the TSR of the Russell 3000 Pharmaceutical & Biotechnology Index over the same period, as follows: less than 25th percentile=0% of target, 25th percentile=50% of target, 50th percentile=100% of target, 75th percentile=200% percent of target, 90th percentile or higher=300% maximum. The grant date fair value is based on a Monte-Carlo simulation model. | | (3) The restricted stock units will vest 25% on each one year anniversary of the vesting commencement date of July 15, 2024 until fully vested on the fourth anniversary of the vesting commencement date, subject to continuing service. The grant date fair value is based on the market price of the stock on the grant date. | | (4) The restricted stock units will vest 33% on April 22, 2026 and each anniversary until fully vested on the fourth anniversary of the vesting commencement date of April 22, 2024, subject to continuing service. The grant date fair value is based on the market price of the stock on the grant date. | | (5) The restricted stock units vested immediately upon the grant of a pro-rated restricted stock unit award granted to Mr. Binder upon his appointment to the Board. The shares subject to such award shall not be delivered until there is a separation of service, such as through resignation or retirement from the Board or death. |

  51. CEO Pay Ratio

    CEO Pay Ratio As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our median employee and the annual total compensation of Mr. Michael Castagna, our Chief Executive Officer. In calculating the annual total compensation, we used the actual base salary in 2024, the actual cash short-term incentive compensation paid in 2025 for performance in 2024, the grant date fair value of the equity awards granted in 2024, and the value of all other compensation, contributions under the 401(k) plan and medical benefits. We identified the median employee by examining the 2024 total compensation for all individuals, excluding our CEO, who were employed by us on December 31, 2024. We included all employees, as all our employees are U.S.-based. The annual total compensation for 2024 was $176,105 for our median employee and $9,490,628 for Mr. Castagna. The resulting ratio of our CEO’s pay to the pay of our median employee for 2024 is approximately 54 to 1.
