Voting matters

Company Overview

We are a biopharmaceutical company committed to researching, developing and commercializing transformative therapeutics to treat high-prevalence retinal diseases. We are focused on bringing new science to the design and manufacture of next generation retinal medicines to prevent and treat the leading causes of blindness globally. Our antibody biopolymer conjugate platform, or ABC Platform^TM, uses molecular engineering to merge the fields of antibody-based and chemistry-based therapies and is at the core of Kodiak’s discovery engine. Kodiak’s lead product candidate, tarcocimab tedromer (“tarcocimab” or “KSI-301”), is a novel anti-VEGF antibody biopolymer conjugate being developed for the treatment of retinal vascular diseases including diabetic eye diseases, the leading cause of blindness in working-age patients in the developed world, and wet age-related macular degeneration (“AMD”), the leading cause of blindness in

		2023 PROXY STATEMENT			1

elderly patients in the developed world. The tarcocimab clinical program is designed to assess the product candidate’s durability, efficacy and safety in major retinal vascular diseases in parallel, through the GLEAM and GLIMMER studies in diabetic macular edema, the BEACON study in retinal vein occlusion, the GLOW study in non-proliferative diabetic retinopathy and the DAYLIGHT study in wet age-related macular degeneration. Phase 3 topline data across the tarcocimab clinical program are expected in the third quarter of 2023. Kodiak has leveraged its ABC Platform to build a pipeline of product candidates in various stages of development. KSI-501 is our dual inhibitor antibody biopolymer conjugate targeting both VEGF (VEGF-trap) and IL-6 (anti-IL-6 antibody) and is being investigated in a Phase 1 clinical study initially in patients with diabetic macular edema. We are expanding our early research pipeline to include ABC Platform based triplet inhibitors for multifactorial retinal diseases such as dry AMD and glaucoma.

2022 Performance Highlights

We remain committed to our mission of developing transformative therapies for high prevalence retinal diseases. In early 2022, we experienced a set-back with our Phase 2b/3 study in wet AMD that did not meet its primary efficacy endpoint leading to a substantial drop in our share price. Despite this set-back, we made steady operational progress with our tarcocimab pivotal program in 2022. We reported positive primary results from our Phase 3 BEACON study in patients with macular edema due to retinal vein occlusion (“RVO”). In the study, tarcocimab dosed every two months met the primary endpoint of non-inferior visual acuity gains compared to aflibercept dosed every month. Tarcocimab is the first anti-VEGF therapy to achieve non-inferiority in visual acuity gains while doubling the treatment interval in patients with RVO.

We completed enrollment in all four of our ongoing Phase 3 studies, namely our paired Phase 3 GLEAM/GLIMMER studies in diabetic macular edema (“DME”), our Phase 3 GLOW study in non-proliferative diabetic retinopathy (“NPDR”), and our Phase 3 DAYLIGHT study in wet AMD. We expect to read out topline data for all four studies in the third quarter of 2023.

In 2022 we also expanded our development pipeline of product candidates built on our ABC Platform with the filing of the Investigational New Drug (“IND”) application with the US FDA for KSI-501. KSI-501 is an investigational, first-in-class bispecific ABC that is designed to inhibit two mechanisms implicated in retinal diseases: vascular endothelial growth factor (“VEGF”) and interleukin-6 (“IL-6”). We believe KSI-501 has the potential to become a new category of retinal medicines with potentially greater therapeutic efficacy than existing therapies while also benefiting from the promising long-interval durability of Kodiak’s ABC Platform. A Phase 1 study is currently enrolling patients in the United States to evaluate the safety, tolerability and bioactivity of KSI-501 in DME patients.

While engaged in these development efforts, we believe we have demonstrated a disciplined and creative approach to building and financing the company. We believe we remain strongly positioned to execute on our vision for the tarcocimab pivotal program, including the manufacturing activities necessary for regulatory submission, to extend our platform while exploring a new category of retinal medicine with KSI-501 and to continue our unique franchise build in retinal science, technology and medicines development.

As a team, we can look back at the key accomplishments of Kodiak in 2022:

Key Highlights from Fiscal 2022

Corporate Responsibility

Kodiak is committed to the mission of preventing and treating the leading causes of blindness and doing so in a socially responsible and sustainable way. In 2022, we published our inaugural Environmental, Social and Governance (“ESG”) report that outlined our philosophy, focus, activities and commitments to the issues that we believe are vital to deliver meaningful impact over the long-term for our stakeholders, including patients, employees, shareholders and the broader communities in which we operate.

This past year, we worked to build on this foundation by focusing our ESG efforts on those that continue to reflect our priorities as a clinical-stage company seeking to complete Phase 3 clinical trials for our lead candidate, tarcocimab tedromer, and pave the path towards commercialization. Select details are below and for further information please see our ESG report on our website.

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.

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 10, 2023. 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 (chairman), and Drs. Dahiyat and Yang, who currently comprise our audit committee, (ii) Dr. Baker (chairman), Mr. Bancroft and Mr. Profusek, who currently comprise our compensation committee, and (iii) Mr. Profusek (chairman), 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.

		2023 PROXY STATEMENT			11

Leadership Structure

Dr. Perlroth, our Chief Executive Officer, is also the Chairman 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.

In August 2018, our board of directors appointed Mr. Profusek to serve as our lead independent director. As lead independent director, Mr. Profusek presides over periodic meetings of our independent directors, serve as a liaison between the Chairman of our board of directors and the independent directors and performs such additional duties as our board of directors may otherwise determine and delegate.

Board Meetings and Committees

During the year ended December 31, 2022, our board of directors held 8 meetings (including regularly scheduled and special meetings) and no incumbent director attended fewer than 75% 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, except during the COVID-19 pandemic, we encourage, but do not require, directors to attend. All but one of our directors attended our most recent annual meeting of stockholders held on June 7, 2022.

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. Members serve on these committees until their resignation or until otherwise determined by our board of directors.

Audit Committee

The current members of our audit committee are Mr. Bancroft, Drs. Dahiyat and Yang. Mr. Bancroft is the chairman 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 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 is comprised entirely of directors who are independent for purposes of serving on an audit committee. Our audit committee will also:

12		2023 PROXY STATEMENT

The audit committee met four times in 2022. The audit committee operates under a written charter that was adopted by our board of directors. 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 Mr. Bancroft and Mr. Profusek. Dr. Baker is the chairman of our compensation committee. The composition of our compensation committee meets the requirements for independence under current Nasdaq listing standards and SEC rules and regulations. 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 six times in 2022. The compensation committee operates under a written charter that was adopted by our board of directors. 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 chairman 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:

		2023 PROXY STATEMENT			13

Our nominating and corporate governance committee met three times in 2022. The nominating and corporate governance committee operates under a written charter that was adopted by our board of directors. 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, 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.

Although our board of directors does not maintain a specific policy with respect to board diversity, our board of directors believes that the board of directors should be a diverse body, and the nominating and corporate governance committee considers a broad range of backgrounds and experiences. 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 director and committee evaluations.

Board Diversity

14		2023 PROXY STATEMENT

Board Diversity Matrix

The Company and the Board are committed to continue seeking director candidates who would further increase the Board’s diversity. The Company considers diversity more broadly than as defined in Nasdaq standards. The Board currently has one Middle Eastern member, who is classified as “white” in the matrix below pursuant to Nasdaq standards.

For further details, please refer to the following matrix:

Stockholder Recommendations for Nominations to the Board of Directors

The nominating and corporate governance committee will consider candidates for directors recommended by stockholders so long as such recommendations comply with our bylaws and applicable laws. The committee will evaluate such recommendations in accordance with its charter, our bylaws and the regular nominee criteria described above. This process is designed to ensure that our board of directors includes members with diverse backgrounds, skills and experience, including appropriate financial and other expertise relevant to our business. 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 can 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, 1200 Page Mill Road, Palo Alto, CA 94304. For our 2024 annual meeting of stockholders, notice must be received by us no earlier than February 12, 2024, and no later than March 11, 2024. 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.

To date, the nominating and corporate governance committee has not received a timely director nominee from a stockholder or group of stockholders that beneficially owned more than 5% of our voting stock.

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, 1200 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.

		2023 PROXY STATEMENT			15

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 2022. Directors who are also our employees receive no additional compensation for their service as a director. During 2022 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”). For purposes of the 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

16		2023 PROXY STATEMENT

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.

Our board of directors amended and restated the Outside Director Compensation Policy to increase the cash retainers paid to directors effective October 1, 2021. The board cash compensation was adjusted based on a competitive market analysis prepared by Compensia, Inc. and was modified as reflected in the table below. Director compensation is typically reviewed on an annual basis.

Equity Compensation

Initial Options. Subject to the limits on compensation paid to independent 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 with a grant date fair value of approximately $905,800, 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 independent directors set forth in the 2018 Plan, under the 2021 Amended and Restated Outside Director Compensation Policy, each non-employee director is granted an annual option on June 30^th of each year (or the preceding trading day, if June 30^th is not a trading day) to purchase shares of our common stock with a grant date fair value of approximately $466,200, 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 as of 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 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. Based on the decline in the Company’s stock price in February 2022, the board of directors elected to receive an annual option award for 2022 of 25,000 options with a value of $131,965, which was significantly lower than the $466,200 value per the Amended and Restated Outside Director Compensation Policy.

In the event of a change in control of the Company, and unless otherwise agreed, each non-employee director will fully vest in his or her outstanding equity awards, including any initial option or annual option, provided that he or she 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 vote of the holders of a majority of the shares of our common stock present in person 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 2024 Annual Meeting of Stockholders.

Executive Officers

Victor Perlroth, M.D. See “Board of Directors and Corporate Governance — Continuing Directors” for Dr. Perlroth’s biographical information.

Jason Ehrlich, M.D., Ph.D. joined Kodiak as our Chief Medical Officer and Chief Development Officer in September 2018. Dr. Ehrlich, an ophthalmologist, is passionate about improving outcomes for patients with vision-threatening eye diseases through the development of innovative medicines. He is internationally recognized for his leadership and expertise in ophthalmic drug development. Prior to joining Kodiak, Dr. Ehrlich served in an executive capacity as Global Head, Clinical Ophthalmology at Genentech, a member of the Roche Group of pharmaceutical companies. In roles of increasing responsibility at Genentech and Roche from July 2008 to August 2018, Dr. Ehrlich’s efforts as lead clinician for Lucentis in diabetic eye disease resulted in a unanimous FDA Advisory Committee vote and the first-ever FDA approval of an intraocular drug for diabetic macular edema. He then championed further expanding the Lucentis labeling into all forms of diabetic retinopathy, resulting in another first-ever FDA approval. Dr. Ehrlich guided the integration of the ophthalmic drug delivery company ForSIGHT VISION4 into Genentech/Roche after its acquisition, including oversight of the successful Phase II study of the ranibizumab Port Delivery System (now FDA-approved as Susvimo). In his work, Dr. Ehrlich has participated in or overseen numerous supplemental biologics license applications and both FDA and European health authority interactions. He led the global development of lampalizumab towards an innovative new therapy for the dry form of age-related macular degeneration, including design and execution of the pivotal Phase III program that included over 1,800 patients, over 275 sites, and more than 20 countries.

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 following individuals, who were the only individuals serving as our executive officers at the end of 2022:

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

20		2023 PROXY STATEMENT

Under the 2021 LTPIP, options are earned primarily based on our stock price meeting or exceeding specified targets between $200 and $800 per share for a period of 90 consecutive trading days.

Up to 35% of the options can also be earned through the achievement of important operational milestones as follows: (i) up to 25% of the LTPIP options could be earned on approval by the U.S. Food and Drug Administration of a Biologics License Application in respect of a first, second and third major indication (RVO, DME and/or wAMD), and (ii) up to 10% may be earned based on attainment of sales of at least $2.5 billion in a completed fiscal year.

Even after the LTPIP options are earned as described above, they are subject to additional time-based vesting in substantially equal monthly installments over the remaining portion of the seven-year performance period.

All of the LTPIP options granted to our NEOs have an exercise price of $88.21 per share and will provide no realizable value to our NEOs unless and until our stock price exceeds $88.21 per share.

In order to participate in the LTPIP, each NEO had to “opt-in” and agree to forgo a corresponding percentage of annual equity incentive awards for 2021-2028. As a result, Dr. Perlroth’s annual incentive awards for those years have or will be reduced by 75%, and Mr. Borgeson’s and Dr. Ehrlich’s annual incentive awards for those years have or will be reduced by 50%.

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.

22		2023 PROXY STATEMENT

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

		2023 PROXY STATEMENT			23

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 CEO.

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 2022 compensation for each of our named executive officers and making 2022 compensation decisions, the compensation committee retained Compensia, 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 2022, 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 2022, 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:

24		2023 PROXY STATEMENT

Based on these criteria, for 2022, Compensia recommended, and our compensation committee approved the following peer group for use analyzing 2022 compensation:

Using the peer companies listed above, Compensia prepared, and the compensation committee reviewed, a range of market data reference points (generally at the 25^th, 50^th, 60^th and 75^th 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, as well as 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:

2022 Advisory Vote on Executive Compensation

A substantial majority (approximately 90%) of the votes cast at the 2022 annual meeting of stockholders approved the compensation of our named executive officers described in our 2022 proxy statement. Our compensation committee reviewed the results of the 2022 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 2022 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.

		2023 PROXY STATEMENT			25

2022 Executive Compensation Program

Annual Base Salary

In reviewing and adjusting base salaries in June 2022, the compensation committee first assessed current base salary levels against the competitive market analysis prepared by Compensia and determined that certain of our named executive officers trailed the 50^th percentile of our 2022 compensation peer group. The compensation committee determined the market 50^th percentile remained appropriate for these named executive officers, and necessary to remain competitive with companies with whom we compete. Accordingly, the compensation committee increased the base salaries of the named executive officers to the amounts necessary to set their 2022 base salaries at approximately the 50^th percentile of the competitive market data.

Annual Bonuses

Our compensation committee approved our annual bonus program for 2022 in early 2022. The 2022 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 2022 target bonus percentage should remain at 65% for Dr. Perlroth and 45% for both Mr. Borgeson and Dr. Ehrlich. The compensation committee’s decision regarding 2022 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 2022 compensation peer group.

In connection with establishing the 2022 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 2022 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 2022, so our named executive officers’ bonuses were entirely dependent on the achievement of our corporate goals.

26		2023 PROXY STATEMENT

During 2022, management reported regularly to the compensation committee on the status of our performance against these goals and in January 2023, the compensation committee evaluated our performance in relation to the 2022 goals.

After consideration of such performance, the compensation committee concluded that 2022 was a year of important accomplishments during which the Company achieved each 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.

		2023 PROXY STATEMENT			27

Based on our performance relative to the 2022 corporate goals, the compensation committee awarded each of our named executive officers an annual bonus equal to 85% of his target bonus opportunity for 2022, as shown in the table below:

Long-Term Incentive Compensation

In July 2022, 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 2022 equity would be in the form of service-based stock options.

In determining 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. These stock options vest monthly over a four-year period, subject to the NEO’s continued service with us through the applicable vesting date.

The table below shows the 2022 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.

On October 31, 2021, Kodiak stockholders approved the 2021 LTPIP, which for our NEOs are stock options with an exercise price of $88.21 per share. The options are earned primarily based on Kodiak stock price attaining certain goals between $200 and $800 per share for a period of 90 consecutive trading days. In addition, up to 35% of the options can be earned based on certain operational milestones to the extent that those options have not yet been earned through stock appreciation. Specifically, up to 25% of the LTPIP options could be earned on approval by the U.S. Food and Drug Administration of a Biologics License Application in respect of a first, second and third major indication (RVO, DME and/or wAMD), and up to 10% may be earned based on attainment of sales of at least $2.5 billion in a completed fiscal year. If LTPIP options are earned based on the foregoing, they would then become eligible to vest based on time in substantially equal monthly installments over the period of time remaining in the seven-year performance period. In order to participate in the LTPIP, each NEO had to “opt-in” and agree to forgo a corresponding percentage of annual equity incentive awards for the seven-year period from 2021 to 2028. As a result, Dr. Perlroth’s 2021 annual incentive awards were reduced by 75%, and Mr. Borgeson’s and Dr. Ehrlich’s 2021 annual incentive awards were reduced by 50%. Each NEO’s annual awards over the next six years will also be reduced by the same respective percentages. During 2022, the equity incentive awards granted to the NEOs factored in each individual’s 2021 LTPIP election to forego a portion of the awards.

Timing of Equity Award

Annual grants of equity awards to our named executive officers are generally determined and approved at compensation committee meetings, with such meeting date typically serving as the grant date. However, the compensation committee

28		2023 PROXY STATEMENT

may sometimes approve the grant of equity awards to our named executive officers and other employees in advance of its next scheduled meeting, either at a special meeting or by unanimous written consent, in connection with certain new hires, promotions and other circumstances where the compensation committee deems it appropriate to grant such awards. The grant dates for these equity awards are typically the same date that a newly hired executive officer begins employment or the effective date of an executive officer’s promotion, as applicable. All stock options are granted with an exercise price that is not less than the closing price of our common stock on the grant date. We have no plan or practice to time option grants in coordination with the release of non-public information, and we do not time the release of non-public information to affect the value of executive compensation.

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, either outside of or 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 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 unused vacation pay.

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. In 2019, we amended the Section 401(k) Plan to provide employer matching contributions of 100% of employee contributions up to a maximum of 50% of the individual maximum contribution limit allowed under the Internal Revenue Service rules. Company matching contributions for the Section 401(k) plan became effective January 1, 2019. 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 employees 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

		2023 PROXY STATEMENT			29

as our compensation committee determines appropriate. In 2022, we paid Dr. Ehrlich a monthly housing and travel allowance, as reported in the “2022 Summary Compensation Table.” The compensation committee determined that such benefits were reasonable and necessary component of Dr. Ehrlich’s compensation.

Accounting and Tax Considerations

Under Financial Accounting Standard Board ASC Topic 718, or 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). The compensation committee also retains the flexibility to modify compensation that was initially intended to be exempt from the deduction limit under Section 162(m) if it determines that such modifications are consistent with the Company’s business needs.

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 our 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. In addition, we intend to implement a Dodd-Frank Wall Street Reform and Consumer Protection Act-compliant clawback policy as soon as, and to the extent that, the requirements of such clawbacks are finalized by the SEC.

2022 Summary Compensation Table

The following table provides information regarding the compensation of our named executive officers during 2022 and 2021. Note that the large amounts for 2021 appearing in the “Option Awards” column of the summary compensation table reflect principally special one-time LTPIP awards calculated by reference to awards only a seven-year period (plus annual grants). See the description of LTPIP awards, which represent most of the 2021 awards, under “Executive Compensation” above.

For information regarding Dr. Ehrlich’s outstanding equity awards as of December 31, 2022, see the section captioned “2022 Outstanding Equity Awards at Fiscal Year End,” including with respect to acceleration of vesting provisions that apply to certain of his equity awards in certain circumstances.

Equity Plans

The 2021 LTPIP provides that in the event of a “change in control” (as defined in the 2021 LTPIP), each outstanding award will be earned as to an applicable percentage of the award based on the per share consideration received by the Company’s stockholders in such change in control transaction meeting or exceeding the corresponding stock price goal, in accordance with the performance-based vesting requirement, with pro-rata vesting between stock price goals. To the extent less than 35% of the award has vested upon a change in control based on the performance-based requirement, then the award remains eligible to be earned based on the attainment of the operational milestones. The earned award then vests and becomes exercisable in accordance with the service-based requirement; provided, however, that, subject to the participant’s timely execution and delivery of a release and waiver of claims agreement, if (1) on the date 24 months immediately following a change in control, the participant is providing services to the acquiring company as either an employee or a consultant or (2) within 24 months following a change in control, the participant’s employment is terminated without cause, or by the participant for good reason, then in either case, 100% of the portion of the award that has been earned but remains unvested based on the service-based requirement will vest and become exercisable in full, effective as of the date the release becomes effective. In addition, in the event that a successor corporation or its parent or subsidiary does not assume or substitute an equivalent award for any outstanding award, then such award will fully vest and the participant will have the right to exercise the portion of the award that has been earned as of the date of such change in control. If an award is not assumed or substituted, the administrator will notify the participant in writing or electronically that such award will be exercisable for a period of time determined by the administrator in its sole discretion and the award will terminate upon the expiration of such period. For additional details regarding the vesting conditions applicable to the 2021 LTPIP awards.

The 2018 Plan provides that in the event of our merger with or into another corporation or other entity or a “change in control” (as defined in the 2018 Plan), each outstanding award will be treated as the administrator determines, except that if a successor corporation or its parent or subsidiary does not assume or substitute an equivalent award for any outstanding award, then such award will fully vest, all restrictions on such award will lapse, all performance goals or other vesting criteria applicable to such award will be deemed achieved at 100% of target levels, and such award will become fully exercisable, if applicable, for a specified period prior to the transaction. The award will then terminate upon the expiration of the specified period of time.

34		2023 PROXY STATEMENT

Under our 2015 Share Incentive Plan (the “2015 Plan”), unless otherwise described in an award agreement, in the event of a corporate transaction (as defined in the 2015 Plan), each outstanding option will either be (1) assumed or an equivalent option or right will be substituted by the successor corporation (or a parent or subsidiary of the successor corporation), or (2) terminated in exchange for a payment of cash, securities and/or other property equal to the excess of the fair market value of the portion of the shares underlying the portion of the option that is vested and exercisable immediately prior to the consummation of the corporate transaction over the per share exercise price of the option. If the successor corporation (or a parent or subsidiary of the successor corporation) does not agree to such assumption, substitution, or exchange, each such option will terminate upon the completion of the corporate transaction. Unless a participant’s award agreement, employment agreement or other written agreement provides otherwise, if the corporate transaction constitutes a triggering event (as defined in the 2015 Plan) and any outstanding option held by a participant is to be terminated (in whole or in part), each such option will become fully vested and exercisable before the completion of the triggering event at such time and on such conditions as the administrator determines. The administrator will notify the participant that the option will terminate at least five days before the date the option terminates.
