This proxy statement contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”), and the Private Securities Litigation Reform Act of 1995. These forward-looking statements are not based on historical fact and include statements regarding: Kodiak’s intention to file a Biologics License Application ("BLA") in diabetic retinopathy, retinal vein occlusion and wet AMD in 2026; expectations regarding the timing of topline data readouts from the DAYBREAK Phase 3 study for both Zenkuda and KSI-501; expectations regarding topline data readouts from the PEAK and PINNACLE Phase 3 studies; and the development of an AI-powered wearable headset with potential applications in retina care, alongside broader opportunities in identity security and cognitive science. Forward-looking statements generally include statements that are predictive in nature and depend upon or refer to future events or conditions, and often include words such as “anticipate,” “believe,” “could,” “expect,” “intend,” “may,” “plan,” “pursue,” “should,” “will,” “would” and other similar expressions, among others. Forward-looking statements are based on management’s current expectations of future events and are subject to risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to: the risk that the completed Phase 3 studies for Zenkuda may not be sufficient to support a BLA submission or approval in diabetic retinopathy, retinal vein occlusion or wet AMD; the risk that a BLA for tarcocimab tedromer or any other product candidate may not be accepted by, or receive approval from, the FDA or foreign regulatory agencies when expected or at all; the risk that cessation, modification or delay of any ongoing clinical studies and Kodiak’s development of Zenkuda, KSI-501, KSI-101 or any other product candidate may occur; the risk that safety, efficacy and durability data observed in Kodiak’s product candidates in current or prior studies may not continue or persist; the risk that KSI-501 may not inhibit VEGF and IL-6 or have an impact on the treatment of patients as expected, and that preclinical data suggesting the possibility that KSI-501 may be a disease-modifying therapy may not translate to clinical outcomes; the risk that the DAYBREAK Phase 3 study for Zenkuda or KSI-501 may not achieve its primary endpoint or may not do so on the anticipated timeline; the risk that the PEAK Phase 3 study for KSI-101 may not achieve its primary endpoint or may not do so on the anticipated timeline; the risk that any one or more of Kodiak’s product candidates may not be successfully developed, approved or commercialized; the risk that Kodiak’s research and development efforts and ability to advance product candidates into later stages of development may fail; the risk that sufficient capital may not be available as expected, or at all, to complete the development of any products; adverse conditions in the general domestic and global economic markets, which may significantly impact Kodiak’s business and operations, including its clinical trial sites, as well as the business or operations of its manufacturers, contract research organizations, or other third parties with whom Kodiak conducts business; as well as the other risks identified in the section entitled “Risk Factors” in Kodiak’s Annual Report on Form 10-K for the year ended December 31, 2025, as well as discussions of potential risks, uncertainties and other important factors in Kodiak’s subsequent filings with the Securities and Exchange Commission (“SEC”).

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Our business affairs are managed under the direction of our board of directors, which is currently composed of seven members. Six of our directors are “independent” under the listing standards of The Nasdaq Stock Market (“Nasdaq”). Our board of directors is divided into three staggered classes of directors. At each annual meeting of stockholders, a class of directors will be elected for a three-year term to succeed the same class whose term is then expiring.

Our directors beneficially own in the aggregate 29,786,724 shares of common stock, or 43% of our shares of common stock outstanding and subject to options and other rights to acquire shares of common stock that are exercisable on or before the 60th day after March 31, 2026. Excluding such exercisable options and rights, our directors beneficially own 22,951,172 shares of common stock, or 37% of our shares of common stock outstanding as of March 31, 2026. See “Security Ownership of Certain Beneficial Owners and Management”. Each director’s term continues until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. This classification of our board of directors may have the effect of delaying or preventing changes in control of our company.

The following table sets forth the names and certain other information for each of the nominees for election as a director and for each of the continuing members of our board of directors, including their respective ages as of April 6, 2026. Proxies may not be voted for a greater number of persons than the number of nominees named.

Director Independence

Our board of directors has undertaken a review of its composition, the composition of its committees and the independence of directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning his or her background, relevant identified transactions, employment and affiliations, including family relationships, the board of directors has determined that none of Mr. Profusek, Mr. Bancroft and Drs. Levy, Dahiyat, Yang or Baker, representing six of our seven directors, has a relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is an “independent director” as defined under the rules of Nasdaq. The board of directors reviews on an annual basis the independence standards for those committees established by applicable SEC rules and the rules of Nasdaq and has also determined that (i) Mr. Bancroft (chair), and Drs. Dahiyat and Yang, who currently comprise our audit committee, (ii) Dr. Baker (chair), and Messrs. Bancroft and Profusek, who currently comprise our compensation committee, and (iii) Mr. Profusek (chair), Drs. Baker and Levy, and Mr. Bancroft, who comprise our nominating and corporate governance committee, satisfy such standards. In making this determination, our board of directors considered the relationships that each non-employee director has with us and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

Leadership Structure

Dr. Perlroth, our Chief Executive Officer, is also the Chair of our board of directors. Our board of directors believes that having our Chief Executive Officer also serve as the Chairman of our board of directors provides us with optimally effective leadership, providing a single, clear chain of command to execute our strategic initiatives and business plan and acting as a bridge between management and our board of directors and is thus in our best interests and those of our stockholders. Dr. Perlroth co-founded our company, and our board of directors believes that Dr. Perlroth’s years of management experience in the pharmaceutical industry as well as his extensive understanding of our business, operations and strategy make him well qualified to serve as Chairman of our board.

Mr. Profusek serves as our lead independent director. As lead independent director, Mr. Profusek presides over executive sessions conducted in meetings of our independent directors, serves as a liaison between senior management and the independent directors and performs such additional duties as our board of directors may otherwise determine and delegate.

Board Meetings and Committees

Our board of directors held seven meetings in 2025 (including regularly scheduled and special meetings) and no incumbent director attended fewer than 94% of the total number of meetings of the board of directors and the committees of which such director was a member.

Although we do not have a formal policy regarding attendance by members of our board of directors at annual meetings of stockholders, all directors attended our 2025 annual meeting of stockholders.

Our board of directors has an audit committee, a compensation committee and a nominating and corporate governance committee, each of which has the composition and responsibilities described below.

Audit Committee

The current members of our audit committee are Mr. Bancroft and Drs. Dahiyat and Yang. Mr. Bancroft is the chair of the audit committee. The composition of our audit committee meets the requirements for independence under current Nasdaq listing standards and SEC rules and regulations. Each member of our audit committee meets the independence and financial literacy requirements of Nasdaq. Our board of directors has determined that each of Mr. Bancroft and Dr. Dahiyat are audit committee financial experts, as that term is defined under the SEC rules implementing Section 407 of the Sarbanes-Oxley Act of 2002, and possesses financial sophistication, as defined under the rules of Nasdaq.

Our audit committee oversees our corporate accounting and financial reporting process and assists our board of directors in monitoring our financial systems. Our audit committee will also:

The audit committee met five times in 2025. A copy of the Audit Committee Charter is available on our website at ir.kodiak.com/corporate-governance/governance-overview.

Compensation Committee

The current members of our compensation committee are Dr. Baker and Messrs. Bancroft and Profusek. Dr. Baker is the chair of our compensation committee. The members of our compensation committee meet the independence requirements established by Nasdaq listing standards and SEC rules. Each member of the compensation committee is also a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act.

Our compensation committee oversees our compensation policies, plans and benefits programs. The compensation committee will also:

Our compensation committee met five times in 2025. A copy of the Compensation Committee Charter is available on our website at ir.kodiak.com/corporate-governance/governance-overview. Pursuant to its charter, the compensation committee may form subcommittees and delegate to such subcommittees any power and authority the compensation committee deems appropriate, excluding any power or authority required by law, regulation or listing standard to be exercised by the compensation committee as a whole.

Nominating and Corporate Governance Committee

The current members of our nominating and corporate governance committee are Messrs. Profusek and Bancroft and Drs. Baker and Levy. The chair of the nominating and corporate governance committee is Mr. Profusek. The composition of our nominating and corporate governance committee meets the requirements for independence under current Nasdaq listing standards and SEC rules and regulations.

Our nominating and corporate governance committee oversees and assists the board of directors in reviewing and recommending nominees for election as directors. The nominating and corporate governance committee will also:

Our nominating and corporate governance committee met two times in 2025. A copy of the Nominating and Corporate Governance Committee Charter is available on our website at ir.kodiak.com/corporate-governance/governance-overview.

Our board of directors may from time to time establish other committees.

Considerations in Evaluating Director Nominees

The nominating and corporate governance committee uses a variety of methods for identifying and evaluating director nominees. In its evaluation of director candidates, the nominating and corporate governance committee will consider the current size and composition of the board of directors and the needs of the board of directors and the respective committees of the board of directors. Some of the qualifications that the nominating and corporate governance committee considers include, without limitation, issues of character, integrity, judgment, diversity of backgrounds and experience, gender, age, independence, skills, education, expertise, business acumen, business experience, length of service, understanding of our company’s business and other commitments. Other than the foregoing, there are no stated minimum criteria for director nominees.

In making determinations regarding nominations of directors, the nominating and corporate governance committee may take into account the benefits of diverse viewpoints. The nominating and corporate governance committee also considers these and other factors as it oversees the annual board of directors and committee evaluations.

Stockholder Recommendations for Board Nominations

The nominating and corporate governance committee will consider candidates for directors recommended by stockholders. Eligible stockholders wishing to recommend a candidate for nomination should contact our Corporate Secretary in writing. Such recommendations must include information about the candidate and the nominating stockholder, including with respect to any holdings of our securities, and a signed letter from the candidate confirming willingness to serve on our board of directors. The committee has discretion to decide which individuals to recommend for nomination as directors.

A stockholder of record may nominate a candidate directly for election to the board of directors by complying with the procedures in Section 2.4(ii) of our bylaws. Any eligible stockholder who wishes to submit a nomination should review the requirements in the bylaws on nominations by stockholders. Any nomination should be sent in writing to Kodiak Sciences Inc., Attention: Corporate Secretary, 1250 Page Mill Road, Palo Alto, CA 94304. For our 2027 annual meeting of stockholders, notice must be received by us no earlier than February 2, 2027, and no later than March 4, 2027. The notice must set forth the information required by Section 2.4(ii)(b) of our bylaws and otherwise must comply with applicable federal and state law.

Stockholder Communications with the Board of Directors

Stockholders wishing to communicate with a non-management member of the board of directors may do so by writing to such director, and mailing the correspondence to: Kodiak Sciences Inc., Attention: Corporate Secretary, 1250 Page Mill Road, Palo Alto, CA 94304. All such stockholder communications will be forwarded to the appropriate committee of the board of directors or non-management director.

Corporate Governance Guidelines and Code of Business Conduct and Ethics

Our board of directors has adopted Corporate Governance Guidelines. These guidelines address, among other items, the responsibilities of our directors, the structure and composition of our board of directors and corporate governance policies and standards applicable to us in general. In addition, our board of directors has adopted a Code of Business Conduct and Ethics that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer and other executive and senior financial officers. The full text of our Corporate Governance Guidelines and Code of Business Conduct and Ethics is posted on the Corporate Governance portion of our website at ir.kodiak.com/corporate-governance/governance-overview. We will post amendments to our Corporate Governance Guidelines and Code of Business Conduct and Ethics or waivers of the same for directors and executive officers on the same website.

Insider Trading Policy

Our board of directors has adopted insider trading policies and procedures that govern the purchase, sale, and other dispositions of our securities by our directors, officers and employees. We believe these policies and procedures are reasonably designed to promote compliance with insider trading laws, rules, and regulations, and applicable listing standards. A copy of our insider trading policy is incorporated by reference as an exhibit to our Annual Report on Form 10-K for our fiscal year ended December 31, 2025.

Risk Management

Our board of directors has an active role, as a whole and also at the committee level, in overseeing the management of our risks. Our board of directors is responsible for general oversight of risks and regular review of information regarding our risks, including risks arising out of our business generally. Our compensation committee is responsible for overseeing the management of risks relating to our executive compensation plans and arrangements. Our audit committee is responsible for overseeing the management of our risks relating to accounting matters and financial reporting. Our nominating and corporate governance committee is responsible for overseeing the management of our risks associated with the independence of our board of directors and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, our entire board of directors is regularly informed through discussions with committee members about such risks. Our board of directors believes its administration of its risk oversight function has not affected the board of directors’ leadership structure.

Prohibitions on Hedging and Transactions Involving Equity or Derivative Securities

Our insider trading policy prohibits our non-employee directors, officers, employees, consultants, contractors and agents from among other things, short sales, hedging of stock ownership positions and transactions involving derivative securities relating to our common stock.

Non-Employee Director Compensation

The following table provides information regarding compensation paid by us to our non-employee directors during 2025. Directors who are also our employees receive no additional compensation for their service as a director. During 2025 one director, Dr. Perlroth, our Chief Executive Officer and Chairman, was an employee. Dr. Perlroth’s compensation is discussed under the caption “Executive Compensation.”

Outside Director Compensation Policy

Our board of directors has approved a compensation policy for our non-employee directors (the “Outside Director Compensation Policy”), effective August 5, 2024. For purposes of the Outside Director Compensation Policy, our board of directors has classified each director into one of the two following categories: (1) an “employee director,” is a director who is employed by us and (2) a “non-employee director,” is a director who is not an employee director. Only non-employee directors receive compensation under the Outside Director Compensation Policy. Non-employee directors receive compensation in the form of equity and cash under the Outside Director Compensation Policy, as described below. We believe our Outside Director Compensation Policy provides reasonable compensation to our non-employee directors that is appropriately aligned with our peers and is commensurate with the services and contributions of our non-employee directors. All directors will be reimbursed for expenses in their capacities as directors in accordance with our standard expense reimbursement policy. Director compensation is typically reviewed on an annual basis.

Cash Compensation

Equity Compensation

Initial Options. Subject to the limits on compensation paid to non-employee directors set forth in our 2018 Equity Incentive Plan (the “2018 Plan”), under the Outside Director Compensation Policy, each person who first becomes a non-employee director (other than a person that ceases to be an employee of ours but remains a director of ours) will be granted an initial option to purchase shares of our common stock equal to two times the number of shares subject to an Annual Award, which option will be effective on the first trading date on or after the date on which such person first becomes a non-employee director, whether through election by our stockholders or appointment by our board of directors to fill a vacancy. Each initial option will vest as to 1/3rd of the shares subject to the initial option on the one-year anniversary of the date of grant and as to 1/36th of the shares subject to the initial option each month thereafter, in each case, subject to continued service through each applicable vesting date.

Annual Options. Subject to the limits on compensation paid to non-employee directors set forth in the 2018 Plan, under the Outside Director Compensation Policy, each non-employee director is granted an annual option on June 30th of each year (or the preceding trading day, if June 30th is not a trading day) to purchase 40,000 shares of our common stock, provided that such director has served on our board of directors for at least the preceding 12 months as of the grant date. Each non-employee director who has served on our board of directors for less than 12 months preceding the grant date will receive a prorated award based on the number of days during the prior 12 months such director has served on our board of directors. Each annual option will fully vest and become exercisable on the earlier of (1) the one-year anniversary of the date of grant of the annual option and (2) the day prior to the date of the annual meeting of our stockholders that occurs in the fiscal year following the grant of such annual option, in each case, subject to continued service through the applicable vesting date.

In the event of a change in control of the Company, and unless otherwise agreed, each non-employee director will fully vest in such director’s outstanding equity awards, including any initial option or annual option, provided that such director continues to be a non-employee director through such date.

PROPOSAL NO. 2

ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

Under Section 14A of the Exchange Act, the Company’s stockholders are entitled to vote to approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed in this proxy statement in accordance with SEC rules (a “say-on-pay” vote).

This vote is not intended to address any specific item of compensation, but rather the overall compensation of the Company’s named executive officers and the philosophy, policies and practices described in this proxy statement. The compensation of the Company’s named executive officers subject to the vote is disclosed in the section titled Executive Compensation, the compensation tables and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, the Company believes that its compensation policies and decisions are designed to meet two objectives: (1) to attract and retain talented and skilled executives by paying for performance and (2) to align the compensation of our named executive officers with our stockholders through an appropriate mix of short-term and long-term compensation. Compensation of the Company’s named executive officers is designed to enable the Company to attract and retain talented and experienced executives to lead the Company successfully in a competitive environment.

Accordingly, our board of directors is asking the stockholders to indicate their support for the compensation of the Company’s named executive officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the section titled Executive Compensation, compensation tables and narrative discussion that accompanies the compensation tables, is hereby APPROVED.”

Because the vote is advisory, it is not binding on the board of directors, the compensation committee or the Company. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to the board of directors and the compensation committee, and accordingly the board of directors and the compensation committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

Advisory approval of this proposal requires the affirmative vote of a majority of the voting power of the shares of our common stock present online or represented by proxy and entitled to vote on the matter at the annual meeting. Unless the board of directors decides to modify its policy regarding the frequency of soliciting advisory votes on the compensation of the Company’s named executive officers, the next scheduled say-on-pay vote will be at the 2027 Annual Meeting of Stockholders.

EXECUTIVE OFFICERS

The following table sets forth the names and positions of our executive officers, including their ages as of April 6, 2026. Officers are elected by the board of directors to hold office until their successors are elected and qualified.

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

EXECUTIVE COMPENSATION

In reviewing this section, please note that, we are a “smaller reporting company” as defined in the Exchange Act and are not required to provide a “Compensation Discussion and Analysis” of the type required by Item 402(b) of Regulation S-K. The following compensation disclosure is intended to comply with requirements applicable to smaller reporting companies. The disclosure in this section is intended to supplement the SEC-required disclosure and is not a Compensation Discussion and Analysis.

Overview

This section discusses our executive compensation program and policies and how and why our compensation committee arrived at specific compensation decisions for our “named executive officers” (also referred to herein as our “NEOs”) consisting of the individuals listed and pictured below, who were the only individuals serving as our executive officers at the end of 2025.

The important features of our executive compensation program include the following:

Overview of Our Executive Compensation Program

Objectives, Philosophy and Elements of Compensation

The overall objectives of our executive compensation program and policies are to:

Our executive compensation program generally consists of, and is intended to strike a balance among, three principal components: base salary, annual bonuses and long-term incentive compensation in the form of equity awards. We also provide our named executive officers with severance and change in control payments and benefits, as well as other benefits available to all our employees, including retirement benefits under our Section 401(k) plan and participation in our employee health and welfare benefit plans. The following chart summarizes the objectives and key features of the three primary elements of compensation.

In evaluating our executive compensation policies and programs, as well as the short-term and long-term value of our executive compensation plans, we consider both the performance and skills of each of our named executive officers, as well as the compensation paid to executives in similar companies with similar responsibilities. We focus on providing a competitive compensation package which provides significant short-term and long-term incentives for the achievement of measurable corporate objectives. We believe that this approach provides an appropriate blend of short-term and long-term incentives to maximize stockholder value.

In determining the aggregate size of equity grants in any given year, the compensation committee (or our board of directors in the case of our Chief Executive Officer) generally considers the same factors described above under “Base Salary” with respect to performance during the prior fiscal year, as well as the criticality of the executive officer to the long-term achievement of corporate goals. The compensation committee also considers the impact of dilution by reviewing overall share utilization and usage.

We do not have any formal policies for allocating compensation among base salary, annual bonus awards and equity awards, short-term and long-term compensation or among cash and non-cash compensation. Instead, the compensation committee uses its judgment to establish a total compensation package for each named executive officer that is a mix of current, short-term and long-term incentive compensation, and cash and non-cash compensation, that it believes appropriate to achieve the goals of our executive compensation program and our corporate objectives. However, a significant portion of the named executive officers’ target total direct compensation is comprised of target bonus opportunities and long-term equity awards, in order to align the named executive officers’ incentives with the interests of our stockholders and our corporate objectives.

In making executive compensation decisions, the compensation committee generally considers each named executive officer’s target total direct compensation, which consists of base salary, target bonus opportunity, which together with base salary we refer to as target total cash compensation and long-term equity awards (valued based on an approximation of grant date fair value).

Role of the Compensation Committee and Executive Officers in Setting Executive Compensation

The compensation committee reviews and oversees our executive compensation program, policies and plans, and it reviews and determines the compensation to be paid to our named executive officers. In making its executive compensation determinations, the compensation committee considers recommendations from our Chief Executive Officer for our named executive officers other than himself. In making his recommendations, our Chief Executive Officer receives internal input from our management team and has access to various third-party compensation surveys and compensation data provided by the compensation consultant to the compensation committee, as described below. While our Chief Executive Officer discusses his recommendations for the other named executive officers with the compensation committee, he is not present and does not participate in the deliberations concerning, or the determination of, his own compensation. In addition to our Chief Executive Officer, our Chief Financial Officer, as well as members of our management team may also attend compensation committee meetings from time to time and may take part in discussions of executive compensation. The compensation committee discusses and makes final determinations with respect to executive compensation matters without any named executive officers present (other than our Chief Executive Officer as described above). The compensation committee makes recommendations to the full board of directors with respect to its determination of compensation and benefits to our Chief Executive Officer.

The compensation committee meets periodically throughout the year to manage and evaluate our executive compensation program, and generally determines the principal components of compensation (base salary, annual bonus and equity awards) for our named executive officers on an annual basis; however, decisions may occur during the year for new hires, promotions or other special circumstances as our compensation committee determines appropriate. The compensation committee does not delegate its authority to approve named executive officer compensation. The compensation committee does not maintain a formal policy for the timing of equity awards to our named executive officers; awards are generally approved at a meeting of the compensation committee approximately midway through each year.

Role of Our Compensation Consultant

The compensation committee has the authority to retain compensation consultants to assist it in fulfilling its responsibilities. For purposes of evaluating 2025 compensation for each of our named executive officers and making 2025 compensation decisions, the compensation committee retained Compensia, Inc., a national compensation consulting firm, to assist the compensation committee in reviewing our executive compensation program and to ensure that our compensation programs remain competitive in attracting and retaining talented executives.

During 2025, Compensia assisted the compensation committee in developing a group of peer companies to use as a reference in making compensation decisions, developing the compensation committee’s executive pay philosophy, evaluating current pay practices and considering different compensation programs and compensation and corporate governance best practices. As described further below, Compensia also prepared an analysis of our compensation practices with respect to base salaries,

annual bonuses and equity awards against competitive market practices. Compensia reports directly to the compensation committee, which maintains the authority to direct Compensia’s work and engagement, and advises the compensation committee and our human resources department from time to time. Compensia interacts with management to gain access to Company information that is required to perform its services and to understand the culture and policies of our organization. The compensation committee and Compensia meet in executive session with no members of management present as needed to address various compensation matters, including deliberations regarding our Chief Executive Officer’s compensation.

Our compensation committee has assessed the independence of Compensia pursuant to the applicable Nasdaq listing standards and SEC rules, and concluded that Compensia is independent and that the work of Compensia has raised no conflict of interest that would prevent Compensia from independently representing the compensation committee.

Use of Competitive Market Compensation Data

We aim to attract and retain the most highly qualified executive officers in an extremely competitive market. Accordingly, the compensation committee believes that it is important when making its compensation decisions to be informed as to the current practices of comparable public companies with which we compete for top talent. To this end, the compensation committee reviews market data for each named executive officer’s position, compiled by Compensia as described below, including information relating to the compensation for executive officers in the biopharmaceutical industry.

In developing a proposed list of our peer group companies to be used in connection with making compensation decisions for 2025, Compensia examined our compensation philosophy and selected companies that would be appropriate peers based on geography, industry focus, stage of development and market capitalization. Specifically, companies were selected with the following parameters:

Based on these criteria, for 2025, Compensia recommended, and our compensation committee approved, the following peer group for use in analyzing 2025 compensation:

Using the peer companies listed above, Compensia prepared, and the compensation committee reviewed, a range of market data reference points (generally at the 25th, 50th, 60th and 75th percentiles of the market data) with respect to base salary, annual bonuses, equity awards (valued based on an approximation of grant date fair value and as an ownership percentage), target total cash compensation (including base salary and the target annual bonus) and target total direct compensation (total target cash compensation and equity compensation).

The compensation committee reviews these market data reference points and structures each component of compensation (including target total direct compensation) to be competitive with the market. However, the market data is only one of the factors that the compensation committee considers in making compensation decisions, and therefore, individual named executive officer compensation may fall above or below these general guidelines.

Factors Used in Determining Executive Compensation

Our compensation committee sets the compensation of our named executive officers at levels it determines to be competitive and appropriate for each named executive officer, using the professional experience and judgment of compensation committee members. Pay decisions are not made by use of a formulaic approach or benchmark; the compensation committee believes executive pay decisions require consideration of a multitude of relevant factors which may vary from year to year. In making executive compensation decisions, the compensation committee generally takes into consideration the following factors:

2025 Advisory Vote on Executive Compensation

Approximately 94% of the votes cast, excluding abstentions and broker non-votes, at the 2025 annual meeting of stockholders approved the compensation of our named executive officers described in our 2025 proxy statement. Our compensation committee reviewed the results of the 2025 stockholder advisory vote on NEO compensation as one of the many factors considered in connection with the discharge of its responsibilities. Because a substantial majority of our stockholders at the 2025 annual meeting of stockholders voted to approve the compensation of our named executive officers, our compensation committee did not implement changes to our executive compensation program as a direct result of the stockholder advisory vote.

2025 Executive Compensation Program

Annual Base Salary

In reviewing and adjusting base salaries in June 2025, the compensation committee assessed current base salary levels against the competitive market analysis prepared by Compensia to align us competitively with at least the 50th percentile of our 2025 compensation peer group, and to remain competitive with the companies with whom we compete.

Annual Bonuses

In early 2026, our compensation committee approved our 2025 annual bonus program. The 2025 annual bonus each named executive officer was eligible to receive was based on the individual’s target bonus, calculated as a percentage of base salary, or target bonus percentage, and the extent to which we achieved the corporate objectives that our board of directors established for the year. There is no specified minimum or maximum bonus percentage or amount established for the named executive officers.

Specifically, the compensation committee determined that the 2025 target bonus percentage should remain at 65% for Dr. Perlroth and 45% for Mr. Borgeson. The compensation committee’s decision regarding 2025 target bonus percentages for our NEOs was based on a review of a competitive market analysis prepared by Compensia, as well as an assessment of target bonus percentages appropriate to align us competitively with our 2025 compensation peer group.

In connection with establishing the 2025 annual bonus program, the compensation committee approved the corporate goals identified in the table below. In selecting these goals, the compensation committee believed that they were appropriate drivers for our business, as they supported tarcocimab clinical development and advanced our research and discovery pipeline, all while maintaining a solid financial position, which together, would enhance stockholder value. At the time the 2025

corporate goals were set, the compensation committee and management believed that such goals were challenging and achieving them would require not only continued strong research and product development success as well as prudent fiscal and legal management, but also a high level of effort and execution on the part of our named executive officers.

The compensation committee also applied a performance weighting to each goal relative to the overall performance of the Company to reflect the prioritization of key business objectives in the table below. No specific individual objectives were established for any of our named executive officers for 2025, so our named executive officers’ 2025 annual bonuses were entirely dependent on the achievement of our 2025 corporate goals.

During 2025, management reported regularly to the compensation committee on the status of our performance against these goals and in January 2026, the compensation committee evaluated our performance in relation to the 2025 goals.

After consideration of such performance, the compensation committee concluded that 2025 was a year of important advancements during which the Company achieved or exceeded all of our pre-established corporate goals, as further described in the table below. The table below describes each corporate goal as well as the achievements related to each goal.

As shown in the table below, based on our performance relative to the 2025 corporate goals, the compensation committee awarded each of our named executive officers an annual bonus equal to 150% of his target bonus opportunity for 2025.

Long-Term Incentive Compensation

In June 2025, our compensation committee granted an annual service-based equity award to each of our NEOs in the form of an option to purchase common stock.

In determining the form of the annual equity awards for our NEOs, the compensation committee took into consideration both the practices of the companies in our compensation peer group and competitive market data provided by its compensation consultant. The compensation committee determined that the 2025 equity awards would be in the form of service-based stock options.

To determine the value of these equity awards, the compensation committee considered a competitive market analysis of long-term incentive compensation prepared by Compensia using the 60th percentile of the competitive market data as the starting point and then adjusting the value of the annual equity awards as it deemed appropriate in its discretion. In addition, the size of the option award ultimately awarded to each NEO in 2025 was reduced to reflect the elections our NEOs made in connection with the 2021 LTPIP. In October 2021, our NEOs received stock options under the 2021 LTPIP, which vest subject to the achievement of certain stock price goals and operational milestones (and subject to their continued employment) during a seven-year performance period. In connection with receiving these awards, each NEO agreed to forgo a corresponding percentage of the annual equity incentive awards they would otherwise have received for the seven-year period from 2021 to 2028. As a result, Dr. Perlroth’s 2025 annual option award was reduced by 75% and Mr. Borgeson’s 2025 annual option award was reduced by 50%. These stock options vest monthly over a four-year period, subject to the NEO’s continued service with us through the applicable vesting date.

In March 2026, in recognition of his leadership in guiding the Company’s strategy during the years 2023, 2024 and 2025, our compensation committee granted a performance-based stock option award to Dr. Perlroth to acquire up to 175,000 shares of our common stock at an exercise price of $25 per share. Shares subject to the performance-based option will vest as follows based on the 30-day average stock price as measured on June 30, 2027, the Performance Criteria Achievement Date (the "PCAD"). In the event the average stock price on the PCAD is (i) less than $25.00, then zero shares will vest, (ii) greater than or equal to $25.00, then one-third of the shares subject to the option will vest, (iii) greater than $30.00, then two-thirds of the shares subject to the option will vest; or (iv) greater than $35.00, then all the shares subject to the option will vest, subject to Dr. Perlroth’s continued service with us through the PCAD.

The table below shows the 2025 annual service-based equity awards approved by the compensation committee for each of our named executive officers and the final awards, after giving effect to each individual’s 2021 LTPIP election to forego a portion of the awards as described above.

Other Features of Our Executive Compensation Program

Employment Agreements with Our Named Executive Officers

We entered into employment agreements with each of our named executive officers upon their initial commencement of employment with us. Each of our named executive officers is employed “at will” and may be terminated at any time for any reason. All of our named executive officers are eligible for severance and change in control payments and benefits pursuant to the terms of their respective employment agreements, the terms of which are described below under “Severance and Change in Control Payments and Benefits” and “Executive Employment Contracts and Change in Control Arrangements.”

Severance and Change in Control Payments and Benefits

The employment agreements with our named executive officers provide for certain severance payments and benefits (cash payments, payments for benefits continuation and equity acceleration) upon a termination of employment without cause or resignation for good reason, with additional benefits if the termination occurs within the three months prior to or 24 months following a corporate transaction. We do not provide any excise or other tax reimbursement (including “gross up”) payments in connection with severance or change in control transactions. Our compensation committee periodically reviews the severance payments and benefits that we provide, including by reference to market data, to ensure that the payments and benefits remain appropriately structured and at reasonable levels. The compensation committee believes that severance protection payments and benefits are necessary to provide stability among our named executive officers, serve to focus our named executive officers on our business operations, and avoid distractions in connection with a potential change in control transaction or period of uncertainty. A more detailed description of the severance payments and benefits for each of our named executive officers is provided below under “Executive Employment Contracts and Change in Control Arrangements.”

Regardless of the manner in which a named executive officer’s service terminates, the named executive officer is entitled to receive amounts earned during his term of service, including base salary earned and accrued paid time-off.

Section 401(k) Plan and Health Benefits

We maintain a Section 401(k) retirement plan that provides eligible employees with an opportunity to save for retirement on a tax-advantaged basis. Eligible employees, including our named executive officers, are able to defer eligible compensation subject to applicable annual limits under the Internal Revenue Code of 1986, as amended (the “Code”). All participants’ interests in their deferrals are 100% vested when contributed. Effective January 1, 2019, we amended the Section 401(k) plan to provide employer matching contributions of 100% of employee contributions up to a maximum of $10,250. Pre-tax contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. The Section 401(k) plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As a tax-qualified retirement plan, contributions to the Section 401(k) plan and earnings on those contributions are generally not taxable to the employee until distributed from the Section 401(k) plan, and all contributions are deductible by us when made. The Section 401(k) plan also permits contributions to be made on a post-tax basis for those employees participating in the Roth 401(k) plan component.

In addition, we provide health benefits to our named executive officers, on the same basis as to all of our full-time employees. These benefits include, but are not limited to, medical, dental, vision, group life, disability and accidental death and dismemberment insurance plans.

Perquisites and Other Personal Benefits

We generally do not offer perquisites or personal benefits to our named executive officers, although we may from time to time provide reasonable relocation, signing bonuses, retention bonuses or other benefits to our named executive officers as our compensation committee determines appropriate.

Accounting and Tax Considerations

Under FASB ASC Topic 718 (“ASC 718”), the Company is required to estimate and record an expense for each award of equity compensation over the vesting period of the award. We record share-based compensation expense on an ongoing basis according to ASC 718.

Under Section 162(m) of the Code (“Section 162(m)”), compensation paid to each of the Company’s “covered employees” that exceeds $1 million per taxable year is generally non-deductible.

Although the compensation committee will continue to consider tax implications as one factor in determining executive compensation, the compensation committee also looks at other factors in making its decisions and retains the flexibility to provide compensation for our named executive officers in a manner consistent with the goals of our executive compensation

program and the best interests of the Company and its stockholders, which may include providing for compensation that is not deductible by the Company due to the deduction limit under Section 162(m).

Compensation Recovery (“Clawback”) Policy

As a public company, if we are required to restate our financial results due to our material noncompliance with any financial reporting requirements under the federal securities laws as a result of misconduct, the Chief Executive Officer and Chief Financial Officer may be legally required to reimburse the Company for any bonus or other incentive-based or equity-based compensation they receive in accordance with the provisions of Section 304 of the Sarbanes-Oxley Act of 2002. Effective October 2, 2023, we implemented the Incentive Compensation Recoupment Policy, a Dodd-Frank Wall Street Reform and Consumer Protection Act-compliant clawback policy.
