  1. PROPOSAL NO. 1—ELECTION OF THREE CLASS III DIRECTORS

    PROPOSAL NO. 1—ELECTION OF THREE CLASS III DIRECTORS Our board of directors currently consists of ten members. In accordance with the terms of our restated certificate of incorporation and our bylaws, 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 currently divided as follows: •the Class I directors are Linda Bain, John Houston, Ph.D., and Laurie Smaldone Alsup, M.D., and their term expires at the annual meeting of stockholders to be held in 2025; •the Class II directors are Sunil Agarwal, M.D., Leslie V. Norwalk, Esq., and John Young., to be held in 2026; and •the Class III directors are Wendy Dixon, Ph.D., Edward Kennedy, Jr., Everett Cunningham, and Briggs Morrison, M.D., and their term expires at the Annual Meeting. Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires. Our restated certificate of incorporation and our bylaws provide that the authorized number of directors may be changed only by resolution of our board of directors. Our restated certificate of incorporation and bylaws also provide that our directors may be removed only for cause by the affirmative vote of the holders of at least 75% of the votes that all our stockholders would be entitled to cast in an annual election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office. Our board of directors, based on the recommendation of the nominating and corporate governance committee of our board of directors, has nominated three current Class III members, Edward Kennedy, Jr., Everett Cunningham, and Briggs Morrison, M.D., for election as Class III directors at the Annual Meeting. Wendy Dixon, Ph.D.,will not be standing for re-election as a Class III director at the Annual Meeting. Following the Annual Meeting subject to approval of this proposal, our board of directors will consist of nine members. Each of the nominees has indicated a willingness to serve as director, if elected. We have no reason to believe that any of our nominees will be unable to serve. However, if a nominee becomes unable or unwilling to serve, the proxies may be voted for substitute nominees selected by our board of directors, or our board of directors may reduce the number of directors to be elected at the Annual Meeting Our corporate governance guidelines provide that nominees should represent a diverse array of personal and professional characteristics, including gender, racial or ethnic identity, sexual identity, international experience and/or expertise in a particular discipline or field. Our priority in selection of board members is identification of members who will further the interests of our stockholders through their established records of professional accomplishment, the ability to contribute positively to the collaborative culture among our board members, knowledge of our business, understanding of the competitive landscape in which we operate and adherence to high ethical standards. Certain individual qualifications and skills of our directors that contribute to our board of directors’ effectiveness as a whole are described in the following paragraphs.

  11. EXECUTIVE AND DIRECTOR COMPENSATION

    EXECUTIVE AND DIRECTOR COMPENSATION

  12. Compensation Design

    Compensation Design Compensation Philosophy and Objectives The goal of our executive compensation policies and programs is to pay for performance. Within this overarching principle, there are a number of key objectives that our policies and programs are designed to achieve: •Attract and retain individuals with superior ability, technical, and managerial experience; •Align the executives’ interests with those of our stockholders through long-term incentives linked to specific performance; and •Provide market competitive compensation to attract and retain highly qualified individuals who are capable of making significant contributions to the long-term success of the company. Alignment with Company Strategy Our executive compensation policies and programs reinforce our pay-for-performance philosophy. While fixed compensation, such as base salary and benefits, are primarily designed to be competitive in the biopharmaceutical marketplace for employees, a substantial portion of our named executive officers’ compensation is linked to achieving scientific, business, organizational and operational goals. We provide a significant portion of our executive compensation in the form of long-term incentives (stock options and RSUs) that vest over time. These equity awards are a key aspect of our pay-for-performance philosophy and serve to align the interests of our named executive officers with our stockholders, as they are tied to future increases in the value of our stock. Further, we believe that equity awards with a time-based vesting feature promote retention because this feature incentivizes our named executive officers to remain in our employment during the vesting period. The annual cash bonuses paid to our named executive officers are based entirely on corporate performance goals established by the board of directors. Our executives make strategic decisions that influence the company, and we believe it is appropriate to reward performance against corporate performance goals in that case, in line with our pay-for-performance philosophy. The total target compensation (base salary, target annual cash bonuses and equity incentive awards) for our Chief Executive Officer and our other named executive officers in 2023 was primarily performance-based, as shown in the charts below: The compensation committee uses a comparative framework to assess the named executive officers’ total compensation mix, but does not have a pre-established policy for allocating total compensation. Rather, based on blended peer group and broader market data, market competitiveness, expected future contribution, experience, impact and individual performance, and internal parity relative to similar positions within the company, the compensation committee subjectively determines the appropriate level and mix of total compensation, keeping in mind our pay-for-performance compensation philosophy. We believe that this approach results in compensation that: •is at an appropriate level to attract and retain individuals with superior ability, technical, and managerial experience; •provides the appropriate incentives to our executives to make significant contributions to the long-term success of the company, while avoiding incentives for inappropriate risk-taking; and •is fair and competitive without being excessive. Elements of Executive Compensation The primary elements of our executive compensation in program in 2023 were:

  13. Compensation Design

    | Element | Purpose | Key Features and Timing | | Base Salary (fixed cash) | Provide competitive, fixed compensation to attract and retain top executive talent | • Cash-based • Initial base salaries are set at the time of hire, and adjustments to base salaries are considered in conjunction with changes in job responsibilities or annually as part of our merit increase process | | Annual Cash Bonus (“at-risk” cash) | Performance-contingent compensation to motivate and reward individual for attaining rigorous corporate performance goals that relate to our key business objectives | • Cash-based • Based on corporate and individual performance • Generally measured and paid out on an annual basis, typically annually following the close of the previous fiscal year | | Long-term Incentives (“at-risk” equity) | Variable incentive compensation to promote performance, support retention, and create stockholder alignment | • Equity-based • Granted in time-based stock options and RSUs • Based on blended peer group and broader market data, market competitiveness, expected future contribution, experience, impact and individual performance, and internal parity relative to similar positions within the company • Generally granted at the time of hire, and annually following the close of the previous fiscal year |

  14. 2023 Compensation Decisions and Outcomes

    2023 Compensation Decisions and Outcomes Role of our Compensation Committee and Executive Officers Our compensation committee, composed entirely of independent directors, is responsible for overseeing our compensation philosophy and operates under a written charter. Among other things, the role of our compensation committee is to seek to ensure that compensation decisions represent sound fiscal policy and enable us to attract and motivate qualified personnel, review and approve, or make recommendations to our board of directors with respect to, the compensation of our Chief Executive Officer and our other executive officers and recommend to the board of directors the compensation of the board of directors. In making its executive compensation determinations, our compensation committee and, if applicable, the full board of directors, considers recommendations from our Chief Executive Officer for our named executive officers (other than himself). In making his recommendations, our Chief Executive Officer has access to various third-party compensation surveys and compensation data provided by our compensation committee’s compensation consultant, as described below. While our Chief Executive Officer discusses his recommendations for the other named executive officers with our compensation committee, he does not participate in the deliberations concerning, or the determination of, his own compensation. From time to time, various other members of management and other employees as well as outside advisors or consultants may be invited by our compensation committee to make presentations, provide financial or other background information or advice or otherwise participate in compensation committee meetings. No named executive officer is present during voting or deliberations on his own compensation. Say-on-Pay Advisory Vote and Stockholder Engagement Each year, pursuant to Section 14(a) of the Exchange Act, we submit to our stockholders a proposal to vote, on an advisory, non-binding basis, to approve the compensation of our named executive officers disclosed in our proxy statement. We first held this vote at the 2021 annual meeting of stockholders. In addition, at our 2021 annual meeting of stockholders, our stockholders voted that we hold such a vote every year. In setting executive compensation, the compensation committee and the board of directors also consider the results of this “say-on-pay” vote. At the 2023 annual meeting of stockholders, this proposal received over 83% of the votes cast by stockholders, excluding broker non-votes and abstentions. While the say-on-pay vote is an advisory, non-binding, vote, we strongly value the opinions of our stockholders as expressed by the results of the say-on-pay vote and believe that stockholder approval of our named executive officer compensation demonstrates an alignment with our stockholders’ interests. Our compensation committee and board will continue to consider stockholder input and monitor our executive compensation program to ensure it aligns the interests of our named executive officers with the interests of our stockholders and adequately addresses any stockholder concerns that may be expressed in future votes. Consistent with the recommendation of our board and the preference of our stockholders as reflected in the non-binding advisory vote on the frequency of future “say-on-pay” votes conducted at our 2021 annual meeting of stockholders, our stockholders will have an opportunity annually to cast an advisory vote in connection with compensation for our named executive officers. Role of our Compensation Consultant As a part of reviewing, recommending and determining (as applicable) compensation for our named executive officers, the compensation committee has engaged Aon’s Human Capital Solutions Practice, a division of Aon plc (“Aon”), as an independent compensation consultant. Aon provides analysis and recommendations to the compensation committee regarding: •trends and emerging topics with respect to executive compensation; •peer group selection for executive compensation benchmarking; •compensation practices of our peer group; •compensation programs for executives, directors and all of our employees; and •stock utilization and related metrics. When requested, Aon consultants attend meetings of the compensation committee, including executive sessions in which executive compensation issues are discussed. Aon is engaged by the compensation committee and meets with management for purposes of gathering information for its analyses and recommendations. In determining to engage Aon, the compensation committee reviewed the independence of Aon taking into consideration relevant factors, including the absence of other services provided to the company by Aon, the amount of fees the company paid to Aon as a percentage of Aon’s total revenue, the policies and procedures of Aon that are designed to prevent conflicts of interest, any business or personal relationship of the individual compensation advisors employed by Aon with an executive officer of the company, any business or personal relationship the individual compensation advisors employed by Aon have with any member of the compensation committee, and any stock of the company owned by Aon or the individual compensation advisors employed by Aon. The compensation committee has determined, based on its analysis in light of all relevant factors, including the factors listed above, that the work of Aon and the individual compensation advisors employed by Aon as compensation consultants to the compensation committee has not created any conflicts of interest, and that Aon is independent pursuant to the independence standards set forth in The Nasdaq Global Select Market listing standards promulgated pursuant to Section 10C of the Exchange Act. Executive Compensation Process The compensation committee compares our executive compensation against a peer group to determine market trends and competitiveness. On an annual basis, the compensation committee reviews the companies in our peer group, as well as Aon’s recommendations regarding which companies should be included in the peer group. The compensation committee may also adjust the peer group to ensure it properly reflects the market in which we compete for executive talent. For purposes of compensation for 2023, the compensation committee retained Aon to evaluate our executive compensation program and recommend a course of action for 2023. In determining the 2023 base salaries, annual cash bonuses and long-term incentives for our named executive officers, our compensation committee relied on the following peer group, or the 2023 Peer Group:

  15. 2023 Compensation Decisions and Outcomes

    * New to the 2023 Peer Group Aon focused on developing a peer group that: •comprised companies operating in the biopharmaceutical industries; •captured comparable companies in terms of market capitalization, revenue, employee size and stage of development; and •allowed for sufficient room for the company to grow. The 2023 Peer Group represents a group of pre-commercial, later stage, oncology or neurology-focused biopharmaceutical/biotechnology companies, with a median market capitalization of $3,110.7 million and a median of 346 employees. Dicerna Pharmaceuticals, Inc., Rubius Therapeutics, Inc., Turning Point Therapeutics, Inc. and Zymeworks, Inc. were each removed from our peer group as their market capitalization and/or stage of development, as applicable, fell outside our targeted range, or due to acquisition, as applicable. Based on the 2023 Peer Group, Aon prepared an assessment that included pay levels and compensation practices from public SEC filings. Aon supplemented the 2023 Peer Group proxy information with data from the Radford Global Compensation Survey, comprising 71 companies with a median headcount of 348 and a median market capitalization of $2.4 billion, which provides a broader market representation of companies and deeper position reporting. To arrive at competitive market compensation, market data collected from the 2023 Peer Group and the Radford Global Compensation Survey was blended equally to form a composite assessment. In analyzing and setting our executive compensation program for 2023, the board of directors and the compensation committee, as applicable, compared certain aspects of our named executive officers’ compensation to the compensation levels included in this composite assessment. Based on the results of the assessment, the board of directors and the compensation committee, as applicable, determined that compensation levels for our named executive officers in 2023 generally reflected market competitive ranges. Base Salaries The base salary for our Chief Executive Officer is determined annually by the board of directors, upon recommendation by the compensation committee. Base salaries for our named executive officers other than our Chief Executive Officer are recommended by our Chief Executive Officer to the compensation committee for approval. Each such determination is based on the scope of each officer’s responsibilities along with his respective experience and contributions to the company during the prior year. When reviewing base salaries, the board of directors and compensation committee, as applicable, takes factors into account such as blended peer group and broader market data, market competitiveness, expected future contribution, experience, impact and individual performance, and internal parity relative to similar positions within the company, but does not assign any specific weighting to any factor. The following table presents the base salaries for each of our named executive officers for the years 2022 and 2023, as approved by the board of directors and compensation committee, as applicable. The 2023 base salaries became effective on January 1, 2023.

  16. 2023 Compensation Decisions and Outcomes

    Annual Cash Bonuses Our annual cash incentive program promotes and rewards our executive officers for the achievement of key business and strategic goals. Under this program, cash incentive awards are determined by multiplying each executive officer’s annualized base salary by a target annual bonus percentage and a corporate performance achievement factor established by our board of directors and compensation committee based on our performance as measured against our pre-established corporate goals. For the year ended December 31, 2023, the target annual bonus percentage was 60% for Dr. Houston and 45% for each of Mr. Cassidy, Dr. Peck and Dr. Taylor. Our board of directors and compensation committee, as applicable, set these targets at the beginning of the year and determined that annual cash bonus opportunities were competitive with the market based primarily on data provided by Aon. During and following the last quarter of each year, our senior management team evaluates our company performance. Based on this evaluation, our Chief Executive Officer recommends to our compensation committee any cash awards for executives (other than himself) under our annual cash incentive program. Our compensation committee then carefully reviews overall corporate performance. Our board of directors, upon the recommendation of our compensation committee, then further reviews our Chief Executive Officer’s compensation and evaluates our Chief Executive Officer’s contributions to our corporate performance. Our board of directors and compensation committee, as applicable, have the discretion to adjust the size of individual awards upward or downward based on company performance. At the beginning of 2023, the compensation committee and the board of directors established the corporate goals listed in the table below for the calendar year 2023, each overall goal having a designated weighting and relating to key development, strategic and business goals for the company. Our Chief Executive Officer and certain other members of senior management report to the compensation committee and the board of directors on our overall performance against these goals on a regular basis throughout the year. In addition, our compensation committee met with our Chief Executive Officer and certain other members of senior management as part of its annual compensation review and discussed our corporate performance in 2023 and a proposed corporate goal achievement score based on the Company’s actual performance as calculated against the previously-established corporate goals. The Chief Executive Officer then proposed recommendations for cash incentive awards for each of our executive officers other than the Chief Executive Officer. Our board of directors then further evaluated the cash incentive award for our Chief Executive Officer. Because our overall corporate goals allow for some amount of subjective and qualitative assessment, the compensation committee and the board of directors engaged in a number of discussions, including with certain members of senior management, as to the appropriate scoring of the Company’s performance against the goals previously-established corporate goals. The following table sets forth our 2023 corporate goals and the level of achievement against those goals as determined by the compensation committee and the board of directors.

  17. 2023 Compensation Decisions and Outcomes

    As part of its evaluation of our corporate performance, our compensation committee and our board of directors noted various performance outcomes, including certain upside considerations supporting actual level of achievement over 100%, during 2023, including the factors listed below. Based on our overall performance during 2023 against these goals, our compensation committee and our board of directors determined that our overall corporate goals had been achieved at a level of 125%. However, as part of our overall commitment to our employees, we funded a special bonus pool of 5% from the overall bonus pool of 125%. As such, the bonuses awarded to all employees, including our named executive officers, for 2023 are based on a corporate goal achievement level of 120% and a portion of our employee population that contributed significantly to the company in 2023 received additional bonus amount. For the avoidance of doubt, for purposes of calculating annual bonuses for our named executive officers, bonuses were based on achievement of corporate goals at a level of 120%. 2023 Achievement Outcomes:

    (1) Based on past historical practice, annual bonuses actually awarded to each of Dr. Houston, Mr. Cassidy, Dr. Peck and Dr. Taylor were rounded up to the next hundred dollars from $473,542, $248,733, $255,659, $252,102, respectively, at the discretion of our compensation committee and board of directors, as applicable. Long-term Incentives Our equity awards program is designed to: •reward demonstrated leadership and performance; •align our executive officers’ interests with those of our stockholders; •retain our executive officers at least through the term of the awards; •maintain competitive levels of executive compensation; and •motivate our executive officers for outstanding future performance. The market for qualified and talented executives in the biopharmaceutical industry is highly competitive and we compete for talent with many companies that have greater resources than we do. Accordingly, we believe equity compensation is a crucial component of any competitive executive compensation package we offer. Historically, our equity awards have generally taken the form of stock options. In February 2023, our compensation committee determined that, in 2023 our annual equity incentive awards granted to our named executive officers would be in the form of stock options and RSUs, with two thirds of such award in the form of stock options and one third in the form of RSUs. We typically make equity award grants to each of our executive officers upon commencement of employment, annually in conjunction with our review of executive compensation, in connection with a promotion, or as a special incentive. All equity awards to our executive officers are approved by our compensation committee and, other than equity awards to new hires, are typically granted by our compensation committee in the first quarter of the year. The size of equity awards varies among our executive officers based on their positions and annual performance assessments. All stock options granted to our executive officers have exercise prices equal to the fair market value of our common stock on the date of grant, so that the recipient will not realize any value from his options unless our share price increases above the exercise price on the date of grant. Accordingly, this portion of our executive officers’ compensation is at risk and is directly aligned with stockholder value creation. In addition, equity grants to our executive officers typically vest over four years, which we believe provides an incentive to our executives to add value over the long-term and to remain with our company. Typically, the stock options we grant to our executives have a ten-year term and vest as to 25% of the shares on the first anniversary of their grant date and then in equal monthly installments thereafter until the fourth anniversary of such date, and RSU awards we grant to our executives vest as to 25% of the shares on the first anniversary of their grant and then in equal annual installments thereafter until the fourth anniversary of such date. Vesting of equity granted to employees ceases upon termination of employment and exercise rights typically cease three months following termination of employment, except in the case of death or disability, for grants made under our 2018 Plan. Prior to the exercise of an option, or settlement of an RSU, the stock option or RSU holder, as applicable, does not have any rights as a stockholder with respect to the shares subject to such option or RSU, as applicable, including voting rights or the right to receive dividends or dividend equivalents. The compensation committee may approve different award types in the future as part of the overall compensation strategy. Awards made in connection with a new, extended or expanded employment relationship may involve a different mix of equity awards, depending on the compensation committee’s assessment of the total compensation package being offered. In connection with the annual review of each executive officer’s individual performance and consistent with our compensation philosophy, based on a long-term incentive value in line with our 30-day stock price and Black Scholes percentage, in February 2023, our compensation committee approved annual equity incentive awards for our named executive officers. The number of stock options awarded and RSUs to each named executive officer was based on the 30-day average stock price of our common stock on the Nasdaq Global Select Market as of January 6, 2023, which was of $35.00, and Black Scholes percentage of 67.5% of face value. The exercise price for each of these stock options was $34.37, which was equal to the closing price of our common stock on the Nasdaq Global Select Market on the date of grant. The annual equity incentive awards granted to our named executive officers are set forth in the table below:

  37. Pay Ratio

    Pay Ratio As required by the Dodd-Frank Act and SEC rules, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of John Houston, our President and Chief Executive Officer. For 2023, we estimate the pay ratio of the annual total compensation of our President and Chief Executive Officer ($7,627,032 as reported in the 2023 Summary Compensation Table above) to the annual total compensation of our median employee ($266,130) to be approximately 29 to 1. We believe this ratio represents a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. There have been no changes in our employee population or employee compensation arrangements that we believe would significantly impact the calculations of this pay ratio and require us to identify a new median employee. Last year’s reported median employee had anomalous compensation, therefore, consistent with SEC rules, for 2023, we chose to use a substitute employee that was identified near the median and who was viewed as more representative. In 2022, the median employee was identified by examining our total employee population at October 15, 2022 of approximately 400 full-time employees, excluding our President and Chief Executive Officer. We then used base salary, incentive compensation (including annual cash bonuses and long-term incentives) and other incentive payments, as applicable, to determine the annual total compensation of our median employee. We did not make any cost-of-living or other adjustments. The SEC rules for identifying the median compensated 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. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

  49. Director Compensation

    Director Compensation We do not pay any compensation to our President and Chief Executive Officer in connection with his service on our board of directors. The compensation that we pay to our President and Chief Executive Officer is discussed earlier in this “Executive and Director Compensation” section. Under our director compensation program, we pay our non-employee directors a cash retainer for service on the board of directors and for service on each committee on which the director is a member. The chairperson of the board and of each committee receive higher 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 will be prorated for any portion of such quarter that the director is not serving on our board of directors. In June 2023, based on a review of our the cash and equity compensation paid to our board of directors versus directors of our peer companies, and with assistance of Aon, our compensation consultant, we amended our director compensation program to add fees for the lead independent director and approve fees for the science and technology committee, as follows:

  50. Director Compensation

    | | Non-Employee Member Annual Fee ($) | Non-Employee Chairperson Incremental Annual Fee ($) | Lead Independent Director ($) | | Board of Directors | 40,000 | 35,000 | 25,000 | | Audit Committee | 10,000 | 10,000 | — | | Compensation Committee | 7,500 | 7,500 | — | | Nominating and Corporate Governance Committee | 5,000 | 5,000 | — | | Science and Technology Committee | 7,500 | 7,500 | — |

  51. Director Compensation

    We also reimburse our non-employee directors for reasonable travel and other expenses incurred in connection with attending our board of director and committee meetings. In addition, under our director compensation program, as amended in June 2023, each non-employee director receives under the 2018 Plan, upon his or her initial election to our board of directors, equity having an aggregate grant date fair value of $750,000 as calculated by the company in accordance with ASC Topic 718, with two-thirds of the value of such award being issued as an option to purchase common stock, or the Initial Option Grant and one-third of the value of such award being issued in RSUs, or the Initial RSU Grant, subject to the maximum annual compensation limits set forth in the program and such other limits as may be set forth in the 2018 Plan. Subject to the non-employee director’s continued service as a director, (a) the Initial Option Grant will vest with respect to 1/36th of the shares of common stock subject thereto at the end of each successive one-month period following the grant date until the third anniversary of the grant date and (b) the Initial RSU Grant will vest annually over three years until the third anniversary of the grant date, and in the event of a change in control of the Company, the vesting schedule of the Initial Option Grant and the Initial RSU Grant will accelerate in full. The exercise price of the Initial Option Grant will be equal to the fair market value of the common stock on the date of grant, which shall be the closing trading price. Further, on the date of each of our annual meetings of stockholders, each non-employee director who has served on our board of directors for at least six months receives, under the 2018 Plan, equity having an aggregate grant date fair value of $375,000 as calculated by the company in accordance with ASC Topic 718, with two-thirds of the value of such award being issued as an option to purchase common stock, or the Annual Option Grant, and one-third of the value of such award being issued in RSUs, or the Annual RSU Grant, subject to the maximum annual compensation limits set forth in the program and such other limits as may be set forth in the 2018 Plan. Each of the Annual Option Grant and Annual RSU Grant will vest in full on the earlier of the first anniversary of the grant date or the first board of directors meeting held after the following annual meeting of stockholders, subject to the non-employee director’s continued service as a director. All options issued to our non-employee directors under our director compensation program are issued at exercise prices equal to the fair market value of our common stock on the date of grant. Prior to June 2023, each non-employee director received under the 2018 Plan, upon his or her initial election to our board of directors, an option to purchase approximately $750,000 of shares of our common stock based on the closing price of our common stock on the date of grant, subject to the maximum annual compensation limits set forth in the program and such other limits as may be set forth in the 2018 Plan. Each of these options vested in equal monthly installments at the end of each month following the date of grant through the third anniversary of the date of grant, subject to the non-employee director’s continued service as a director, employee, or consultant. Further, on the date of each of our annual meetings of stockholders, each non-employee director who has served on our board of directors for at least six months received, under the 2018 Plan, an option to purchase approximately $375,000 of shares of our common stock, based on the closing price of our common stock on the date of grant, subject to the maximum annual compensation limits set forth in the program and such other limits as may be set forth in the 2018 Plan. Each of these options vested in full on the one-year anniversary of the date of grant (or, if earlier, the date of our next annual meeting of stockholders following the date of grant), subject to the non-employee director’s continued service as a director. All options issued to our non-employee directors under our director compensation program were issued at exercise prices equal to the fair market value of our common stock on the date of grant. The following table sets forth information regarding compensation earned by our non-employee directors during the year ended December 31, 2023. There were no outstanding equity awards held by our non-employee directors as of December 31, 2023 other than as described in footnote 1 to the following table.

PROPOSAL NO. 3—RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2024 Our stockholders are being asked to ratify the appointment by the audit committee of the board of directors of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024.

If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain Deloitte & Touche LLP. If the selection of Deloitte & Touche LLP is ratified, the audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of our company and our stockholders. A representative of Deloitte & Touche LLP is expected to virtually attend the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders. We incurred the following fees from Deloitte & Touche LLP for the audit of the consolidated financial statements and for other services provided during the years ended December 31, 2023 and 2022.
