All statements contained in this proxy statement other than statements of historical fact, including statements regarding our future operating results and financial condition, our business strategy and plans, market growth, and our objectives for future operations, are forward-looking statements.

These statements are not historical facts and are based on current expectations, estimates, and projections about our industry, management’s beliefs, and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, estimates, and uncertainties that are difficult to predict. For a discussion of some of the risks and important factors that could affect our future results and financial condition, see “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, and our other Securities and Exchange Commission (“SEC”) filings, which are available on our website located at https://ir.dayonebio.com under “SEC Filings” in the “Financial Information” section and on the SEC website at www.sec.gov.
All forward-looking statements contained herein are based on information available to us as of the date hereof and you should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, performance, or achievements. We undertake no obligation to update any of these forward-looking statements for any reason after the date of this proxy statement or to conform these statements to actual results or revised expectations, except as required by law.

PROXY STATEMENT FOR THE 2025 ANNUAL MEETING OF STOCKHOLDERS

APRIL 11, 2025
INFORMATION ABOUT SOLICITATION AND VOTING
The accompanying proxy is solicited on behalf of the board of directors of Day One Biopharmaceuticals, Inc. for use at our 2025 Annual Meeting of Stockholders (“Annual Meeting”) to be held virtually at www.virtualshareholdermeeting.com/DAWN2025 on Monday, June 2, 2025 at 10:00 a.m. Pacific Time, and any adjournment, rescheduling or postponement thereof. The Notice and this proxy statement for the Annual Meeting (“Proxy Statement”) and the accompanying form of proxy were first distributed and made available on the Internet to stockholders on or about April 11, 2025. Our Annual Report for the fiscal year ended December 31, 2024 is available with this Proxy Statement by following the instructions in the Notice of Internet Availability of Proxy Materials. In this Proxy Statement, we refer to Day One Biopharmaceuticals, Inc. as “the Company,” “Day One,” “we” or “us.” References to our website in this Proxy Statement are not intended to function as hyperlinks and the information contained on our website is not intended to be incorporated into this Proxy Statement.
INTERNET AVAILABILITY OF PROXY MATERIALS
In accordance with SEC rules, we are using the Internet as our primary means of furnishing proxy materials to stockholders. Consequently, most stockholders will not receive paper copies of our proxy materials. We will instead send these stockholders a Notice with instructions for accessing the proxy materials, including our Proxy Statement and Annual Report, and voting via the Internet. The Notice also provides information on how stockholders may obtain paper copies of our proxy materials if they so choose. We believe this rule makes the proxy distribution process more efficient, less costly, and helps to conserve natural resources.
GENERAL INFORMATION ABOUT THE MEETING
Purpose of the Annual Meeting
You are receiving this Proxy Statement because our board of directors is soliciting your proxy to vote your shares at the Annual Meeting with respect to the proposals described in this Proxy Statement. This Proxy Statement includes information that we are required to provide to you pursuant to the rules and regulations of the SEC and is designed to assist you in voting your shares.
We intend to ensure that our stockholders are afforded the same rights and opportunities to participate virtually as they would at an in-person meeting. We believe the virtual format improves access for stockholders to attend and participate fully and equally in the Annual Meeting because they can join with any Internet-connected device from any location around the world at no cost. Our virtual meeting format helps us engage with all stockholders regardless of size, resources, or physical location, saves us and stockholders time and money, and reduces our environmental impact.
Record Date; Quorum
Only holders of record of our common stock at the close of business on April 7, 2025 (the “Record Date”) will be entitled to vote at the Annual Meeting. At the close of business on the Record Date, we had 101,353,781 shares of common stock outstanding and entitled to vote. At the close of business on the Record Date, our directors and executive officers and their respective affiliates beneficially owned and were entitled to vote 2,227,732 shares of common stock at the Annual Meeting, or approximately 2.2% of the voting power of the shares of our common stock outstanding on such date. For at least ten days prior to the Annual Meeting, a complete list of the stockholders entitled to vote at the Annual Meeting will be available for examination by any stockholder for any purpose relating to the Annual Meeting. Stockholders can request the list of stockholders through our website located at https://ir.dayonebio.com under “Contact IR” in the “Investor Resources” section.
The holders of a majority of the voting power of the shares of our common stock entitled to vote at the Annual Meeting as of the Record Date must be present at the Annual Meeting in order to hold the Annual Meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the Annual Meeting if you are present and vote at the Annual Meeting or if you have properly submitted a proxy.

TABLE OF CONTENTS

Participating in the Annual Meeting
Instructions on how to attend the Annual Meeting are posted at www.virtualshareholdermeeting.com/DAWN2025.
You may log in to the meeting platform beginning at 9:45 a.m. Pacific Time on June 2, 2025. The meeting will begin promptly at 10:00 a.m. Pacific Time.
You will need the 16-digit control number provided in your proxy materials to attend the Annual Meeting at www.virtualshareholdermeeting.com/DAWN2025.
Stockholders of record and beneficial owners as of the Record Date may vote their shares electronically during the Annual Meeting.
If you wish to submit a question during the Annual Meeting, log into the virtual meeting platform at www.virtualshareholdermeeting.com/DAWN2025, type your question into the “Ask a Question” field, and click “Submit.” If your question is properly submitted during the relevant portion of the meeting agenda, we will respond to your question during the live webcast, subject to time constraints. Questions that are substantially similar may be grouped and answered together to avoid repetition. We reserve the right to exclude questions that are irrelevant to meeting matters, irrelevant to the business of Day One, or derogatory or in bad taste; that relate to pending or threatened litigation; that are personal grievances; or that are otherwise inappropriate (as determined by the chair of the Annual Meeting).
If we experience technical difficulties during the meeting (e.g., a temporary or prolonged power outage), we will determine whether the meeting can be promptly reconvened (if the technical difficulty is temporary) or whether the meeting will need to be reconvened on a later day (if the technical difficulty is more prolonged). In any situation, we will promptly notify stockholders of the decision via www.virtualshareholdermeeting.com/DAWN2025. If you encounter technical difficulties accessing our meeting or asking questions during the meeting, a support line will be available on the login page of the virtual meeting website.
Voting Rights; Required Vote
In deciding all matters at the Annual Meeting, as of the close of business on the Record Date, each share of common stock represents one vote. We do not have cumulative voting rights for the election of directors. You may vote all shares owned by you as of the Record Date, including (i) shares held directly in your name as the stockholder of record and (ii) shares held for you as the beneficial owner in street name through a broker, bank, trustee, or other nominee.
Stockholder of Record: Shares Registered in Your Name. If, on the Record Date, your shares were registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the Annual Meeting or vote by telephone, through the Internet or, if you request or receive paper proxy materials, by filling out and returning the proxy card.
Beneficial Owner: Shares Registered in the Name of a Broker or Nominee. If, on the Record Date, your shares were held in an account with a brokerage firm, bank or other nominee, then you are the beneficial owner of the shares held in street name. As a beneficial owner, you have the right to direct your nominee on how to vote the shares held in your account, and your nominee has enclosed or provided voting instructions for you to use in directing it on how to vote your shares. However, the organization that holds your shares is considered the stockholder of record for purposes of voting at the Annual Meeting. Because you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from the organization that holds your shares giving you the right to vote the shares at the Annual Meeting.
Each director will be elected by a plurality of the votes cast, which means that the two individuals nominated for election to our board of directors at the Annual Meeting (“Proposal No. 1”) receiving the highest number of “FOR” votes will be elected. You may vote “FOR ALL NOMINEES,” “WITHHOLD AUTHORITY FOR ALL NOMINEES” or “FOR ALL EXCEPT” one or any of the nominees you specify. Ratification of the appointment of PwC as our independent registered public accounting firm for the year ending December 31, 2025 (“Proposal No. 2”)

will be obtained if the number of votes cast “FOR” the proposal at the Annual Meeting exceeds the number of votes “AGAINST” the proposal. Approval, on a non-binding advisory basis, of the compensation of our named executive officers (“Proposal No. 3”) will be obtained if the number of votes cast “FOR” the proposal at the Annual Meeting exceeds the number of votes “AGAINST” the proposal.
Under the Delaware General Corporation Law (“DGCL”), abstentions (shares present at the Annual Meeting and marked “ABSTAIN”) and “WITHHOLD AUTHORITY” votes are counted for purposes of determining whether a quorum is present. At the Annual Meeting, abstentions and proxies marked “WITHHOLD AUTHORITY” will have no effect on Proposal No. 1, Proposal No. 2 or Proposal No. 3.
Broker non-votes occur when shares held by a broker for a beneficial owner are not voted either because (i) the broker did not receive voting instructions from the beneficial owner, or (ii) the broker lacked discretionary authority to vote the shares. Broker non-votes are counted for purposes of determining whether a quorum is present. A broker is entitled to vote shares held for a beneficial owner on “routine” matters without instructions from the beneficial owner of those shares. Absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on “non-routine” matters. At our Annual Meeting, only Proposal No. 2 is considered a routine matter and brokers have discretionary authority to vote on shares that are beneficially owned on Proposal No. 2. If a broker chooses not to vote shares for or against Proposal No. 2, it would have the same effect as an abstention. The other proposals presented at the Annual Meeting are non-routine matters. Broker non-votes are not deemed to be shares entitled to vote on and will have no effect on the outcome of Proposal No. 1, Proposal No. 2 or Proposal No. 3.
Accordingly, we encourage you to provide voting instructions to your broker, whether or not you plan to attend the Annual Meeting.
Recommendations of Our Board of Directors on Each of the Proposals Scheduled to be Voted on at the Annual Meeting
Our board of directors recommends that you vote “FOR ALL NOMINEES” of the Class I directors named in this Proxy Statement, “FOR” the ratification of the appointment of PwC as our independent registered public accounting firm for the year ending December 31, 2025 and “FOR” the approval, on a non-binding advisory basis, of the compensation of our named executive officers.
None of our directors or executive officers has any substantial interest in any matter to be acted upon, other than with respect to Proposal No. 1 and Proposal No. 3.

TABLE OF CONTENTS

If you do not vote and you hold your shares in street name, and your broker does not have discretionary power to vote your shares, your shares may constitute “broker non-votes” (as described above) and will not be counted in determining the number of shares necessary for approval of the proposals. However, broker non-votes will be counted for the purpose of establishing a quorum for the Annual Meeting.
If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on each proxy card and vote each proxy card by telephone, through the Internet or by mail. If you requested or received paper proxy materials and you intend to vote by mail, please complete, sign and return each proxy card you received to ensure that all of your shares are voted.
We strongly recommend that you vote your shares in advance of the meeting as instructed above, even if you plan to attend the Annual Meeting virtually.
Expenses of Soliciting Proxies
We will pay the expenses of soliciting proxies, including preparation, assembly, printing and mailing of this Proxy Statement, the proxy and any other information furnished to stockholders. Following the original mailing of the soliciting materials, we and our agents, including directors, officers, and other employees, without additional compensation, may solicit proxies by mail, email, telephone, facsimile, by other similar means or in person. Following the original mailing of the soliciting materials, we will request brokers, custodians, nominees and other record holders to forward copies of the soliciting materials to persons for whom they hold shares and to request authority for the exercise of proxies. In such cases, we, upon the request of the record holders, will reimburse such holders for their reasonable expenses. If you choose to access the proxy materials or vote through the Internet, you are responsible for any Internet access charges you may incur.
Revocability of Proxies
A stockholder of record who has given a proxy may revoke it at any time before it is exercised at the Annual Meeting by:
delivering to our Secretary by mail a written notice stating that the proxy is revoked;
signing and delivering a proxy bearing a later date;
voting again through the Internet; or
attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy).
Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to revoke a proxy, you must contact that firm to revoke any prior voting instructions.
Voting Results
Voting results will be tabulated and certified by the inspector of elections appointed for the Annual Meeting. The preliminary voting results will be announced at the Annual Meeting. The final results will be tallied by the inspector of elections and filed with the SEC in a current report on Form 8-K within four business days of the Annual Meeting.

TABLE OF CONTENTS

BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD OF DIRECTORS;
CORPORATE GOVERNANCE STANDARDS AND DIRECTOR INDEPENDENCE
We are strongly committed to good corporate governance practices. These practices provide an important framework within which our board of directors and management can pursue our strategic objectives for the benefit of our stockholders.
Corporate Governance Guidelines
Our board of directors has adopted Corporate Governance Guidelines that set forth expectations for directors, director independence standards, board committee structure and functions, and other policies for the governance of the company. Our Corporate Governance Guidelines are available without charge on our website located at https://ir.dayonebio.com under “Documents & charters” in the “Corporate Governance” section. Our nominating and corporate governance committee reviews the Corporate Governance Guidelines periodically, and changes are recommended to our board of directors as warranted.
Board of Directors and Committee Self-Evaluations
Our board of directors is committed to a robust self-evaluation process designed for continuous improvement. As part of this process, our board of directors conducts an annual self-assessment of the performance of the board of directors and its committees, their own performance, and the performance of fellow members of the board of directors. Results from such assessment are aggregated and shared and discussed with our nominating and corporate governance committee and board of directors.
Our board evaluation process is used:
by our board of directors and nominating and corporate governance committee to assess the current composition of our board of directors and its committees and make recommendations for the qualifications, expertise, and characteristics we should seek in identifying potential new directors;
by our board of directors and nominating and corporate governance committee to identify the strengths and areas of opportunity of each member of our board of directors and to provide insight into how each member of our board of directors can be most valuable;
to improve agenda topics of the board of directors and its committees so that information they receive enables them to effectively address the issues they consider most critical; and
by our nominating and corporate governance committee as part of its annual review of each director’s performance when considering whether to nominate the director for re-election to the board of directors.
Board Leadership Structure
Our Corporate Governance Guidelines provide that our board of directors shall be free to choose its chairperson in any way that it considers in the best interests of our company, and that the nominating and corporate governance committee periodically considers the leadership structure of our board of directors and makes such recommendations to our board of directors with respect thereto as appropriate. Our Corporate Governance Guidelines also provide that, when the positions of chairperson and chief executive officer are held by the same person, our board of directors shall designate a “lead independent director” by a majority vote of the independent directors. In cases in which the chairperson and chief executive officer are the same person, the chairperson schedules and sets the agenda for meetings of our board of directors in consultation with the lead independent director, and the chairperson, or if the chairperson is not present, the lead independent director, chairs such meetings. The responsibilities of the lead independent director include: presiding at executive sessions of independent directors, serving as a liaison between the chairperson and the independent directors, consulting with the chairperson regarding the information sent to our board of directors in connection with its meetings, having the authority to call meetings of the independent directors, being available under appropriate circumstances for consultation and direct communication with stockholders, and performing such other functions and responsibilities as requested by our board of directors from time to time.
Currently, our board of directors believes that it should maintain flexibility to select the chairperson of our board of directors and adjust our board leadership structure from time to time. The positions of Chief Executive Officer and chair of our board of directors are currently held by two different individuals (Jeremy Bender and Garry Nicholson, respectively). Jeremy Bender has served as our Chief Executive Officer since September 2020 and Garry Nicholson
11

TABLE OF CONTENTS

as the chair of our board of directors since September 2022. This structure allows our Chief Executive Officer to focus on our day-to-day business while our chair leads our board of directors in its fundamental role of providing advice to, and independent oversight of, management. Our board of directors believes that Mr. Nicholson’s strategic vision for our business and deep knowledge of our industry make him well qualified to serve as chair of our board of directors. Our board of directors believes that its independence and oversight of management is maintained effectively through this leadership structure, the composition of our board of directors and sound corporate governance policies and practices. Any changes to the leadership structure of our board of directors, if made will be promptly disclosed on the “Investors & Media” portion of our website and disclosed in the applicable proxy materials. Our board of directors, in its sole discretion, may seek input from our stockholders on the leadership structure of the board of directors.
Our Board of Directors’ Role in Risk Oversight
Our board of directors, as a whole, has responsibility for risk oversight, although the committees of our board of directors oversee and review risk areas that are particularly relevant to them. The risk oversight responsibility of our board of directors and its committees is supported by our management reporting processes, which are designed to provide visibility to our board of directors and to our personnel that are responsible for risk assessment and information about the identification, assessment and management of critical risks and management’s risk mitigation strategies. These areas of focus include both short-term and long-term competitive, economic, operational, financial (accounting, credit, investment, liquidity and tax), legal, regulatory, cybersecurity, privacy, compliance and reputational risks. Our board of directors reviews strategic and operational risk in the context of discussions, question and answer sessions, and reports from the management team at each regular board meeting, receives reports on all significant committee activities at each regular board meeting, and evaluates the risks inherent in significant transactions. Our audit committee assists our board of directors in fulfilling its oversight responsibilities with respect to risk management.
Each committee of our board of directors meets with key management personnel and representatives of outside advisors to oversee risks associated with their respective principal areas of focus. Our audit committee reviews our major financial risk exposures, our internal control over financial reporting, our disclosure controls and procedures, legal and regulatory compliance, and, among other things, discusses with management and our independent auditor guidelines and policies with respect to risk assessment and risk management. Our compensation committee evaluates our major compensation-related risk exposure and the steps management has taken to monitor or mitigate such exposures. Our nominating and corporate governance committee assesses risks relating to our corporate governance practices, the independence of our board of directors and reviews and discusses the narrative disclosure regarding our board of directors’ leadership structure and role in risk oversight. We believe this division of responsibilities is an effective approach for addressing the risks we face and that our board leadership structure supports this approach.
Cybersecurity Risk Oversight
Securing the information of participants in our studies, medical professionals, team members, and other third parties is important to us. Moreover, our board of directors recognizes the critical importance of maintaining the trust and confidence of our patients, investors, business partners and employees. We have adopted physical, technological, and administrative controls on data security, and have a defined procedure for data incident detection, containment, response, and remediation. While everyone at our company plays a part in managing these risks, oversight responsibility is shared by our board of directors, our audit committee, and management. Further, on an annual basis, our board of directors and the audit committee discuss our approach to cybersecurity risk management with members of the Data Privacy and Security Committee, which includes our Chief Executive Officer, Chief Operating and Financial Officer, General Counsel and Head of Information Technology.
Independence of Directors
The listing rules of the Nasdaq Stock Market LLC (“Nasdaq”) generally require that independent directors constitute a majority of a listed company’s board of directors. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees must be an “independent director.” Under the rules of Nasdaq, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Additionally, compensation committee members must not have a relationship with the listed company that is material to the director’s ability to be independent from management in connection with the duties of a compensation committee member.
12

TABLE OF CONTENTS

In addition, audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or be an affiliated person of the listed company or any of its subsidiaries.
Our board of directors has undertaken a review of the independence of each director and considered whether each 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. As a result of this review, our board of directors determined that each of our directors continuing in their role after the Annual Meeting other than Dr. Bender are “independent directors” as defined under the applicable rules and regulations of the SEC and the listing requirements and rules of Nasdaq. In making these determinations, our board of directors reviewed and discussed information provided by the directors and by us with regard to each director’s business and personal activities and relationships as they may relate to us and our management, including the beneficial ownership of our common stock by each non-employee director and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”
Committees of Our Board of Directors
Our board of directors has established an audit committee, a compensation committee, and a nominating and corporate governance committee. The composition and responsibilities of each committee are described below. Each of these committees has a written charter approved by our board of directors. Copies of the charters for each committee are available without charge on our website, located at https://ir.dayonebio.com under “Documents & charters” in the “Corporate Governance” section. Members serve on these committees until their resignations or until otherwise determined by our board of directors.

The members of our audit committee meet the independence requirements under Nasdaq and SEC rules and regulations. Each member of our audit committee is financially literate. In addition, our board of directors has determined that Ms. Ramasastry is an “audit committee financial expert” as that term is defined in Item 407(d)(5)(ii) of Regulation S-K promulgated under the Securities Act. This designation does not impose any duties, obligations or liabilities that are greater than those generally imposed on other members of our audit committee and our board of directors. Our audit committee is responsible for, among other things:
selecting and hiring our independent registered public accounting firm;
the qualifications, independence and performance of our independent auditors;
the preparation of the audit committee report to be included in our annual proxy statement;

Social and Ethical Practices
We believe that CSR initiatives are important to our business and to creating sustainable value for our stockholders and wider stakeholder group. Our board of directors and management are committed to these initiatives in order to create and maintain an inclusive and safe work environment where our employees can bring their best selves to work each day. As part of our CSR initiatives, we made an active decision to pursue opportunities for learning and engagement that bring people from different backgrounds together into conversation. Our commitment to our employees extends through our recruitment, retention, learning, engagement, community partnerships and competitive pay and benefits. Social and Ethical CSR highlights include:
Company culture. Building a team of individuals from different backgrounds and with different experiences that functions in an inclusive environment is critical to our success as a global company. We seek to recruit, develop, and retain the most talented people from a diverse candidate pool. Day One is committed to providing an environment of mutual respect where equal employment opportunities are available to all applicants. Our management team and employees are expected to exhibit and promote honest, ethical and respectful conduct in the workplace. All of our employees must adhere to a code of conduct that sets standards for appropriate behavior and are required to attend biennial training to help prevent, identify, report and stop any type of discrimination and harassment. All recruitment, hiring, development, training, compensation and advancement at our company is based on qualifications, performance, skills and experience without regard to gender, race and ethnicity.
Competitive pay and benefits. Drug development is a complex endeavor which requires deep expertise and experience across a broad array of disciplines. Biotechnology and pharmaceutical companies, both large and small, compete for a limited number of qualified applicants to fill specialized positions. We monitor our compensation programs closely and provide what we consider to be a very competitive mix of compensation, insurance and wellness benefits for all our employees, as well as participation in our equity and enhanced maternity and paternity programs. To attract qualified applicants, we offer a total rewards package consisting of base salary and cash target bonus, a comprehensive benefits package and equity compensation for all full-time employees. Bonus opportunity and equity compensation increase as a percentage of total compensation based on level of responsibility. Actual bonus payout is based on company and individual performance.
Employee development and training. We focus on attracting, retaining and cultivating talented individuals. We emphasize employee development and training by providing access to a wide range of online and instructor-led development and continual learning programs. Employees are encouraged to attend scientific, clinical and technological meetings and conferences and have access to broad resources they need to be successful.
Governance
We are committed to corporate governance policies and practices demonstrating the highest standards of business ethics. We have procedures in place to help ensure compliance with governmental regulations. We review industry trends and best practices so we can continue to foster an environment centered around accountability. Governance CSR highlights include:
Board of Directors Oversight. Our board of directors recognizes the critical importance of our team and the necessity to ensure a diverse and inclusive work environment. Our board of directors discusses with management issues impacting our employees.
Nominating and Corporate Governance Charter Expansion. The responsibilities of our nominating and corporate governance committee include oversight of our corporate social responsibility programs.
Code of Business Conduct and Ethics Training Compliance. All employees and members of the board of directors are trained in and affirm compliance with our comprehensive Code of Business Conduct and Ethics.

NOMINATIONS PROCESS AND DIRECTOR QUALIFICATIONS

Nomination to the Board of Directors
Candidates for nomination to our board of directors are selected by our board of directors based on the recommendation of the nominating and corporate governance committee in accordance with the committee’s charter, our restated certificate of incorporation and amended and restated bylaws, our Corporate Governance Guidelines and the criteria approved by our board of directors regarding director candidate qualifications. In recommending candidates for nomination, the nominating and corporate governance committee considers candidates recommended by directors, officers, employees, stockholders and others, using the same criteria to evaluate all candidates. Evaluations of candidates generally involve a review of background materials, internal discussions and interviews with selected candidates as appropriate and, in addition, the committee may engage consultants or third-party search firms to assist in identifying and evaluating potential nominees.
Additional information regarding the process for properly submitting stockholder nominations for candidates for membership on our board of directors is set forth below under “Stockholder Proposals to Be Presented at Next Annual Meeting.”
Director Qualifications
With the goal of developing a varied, experienced and highly qualified board of directors, the nominating and corporate governance committee is responsible for developing and recommending to our board of directors the desired qualifications, expertise and characteristics of members of our board of directors, including any specific minimum qualifications that the committee believes must be met by a committee-recommended nominee for membership on our board of directors and any specific qualities or skills that the committee believes are necessary for one or more of the members of our board of directors to possess. Although our board of directors does not establish specific goals with respect to diversity, we seek to achieve a mix of members to our board of directors that represent varying backgrounds and experiences, including with respect to age, gender, race, ethnicity, and occupation.
Because the identification, evaluation and selection of qualified directors is a complex and subjective process that requires consideration of many intangible factors, and will be significantly influenced by the particular needs of our board of directors from time to time, our board of directors has not adopted a specific set of minimum qualifications, qualities or skills that are necessary for a nominee to possess, other than those that are necessary to meet U.S. legal and regulatory rules and the Nasdaq listing requirements and the provisions of our restated certificate of incorporation, amended and restated bylaws, Corporate Governance Guidelines, and charters of the committees of our board of directors. In addition, neither our board of directors nor our nominating and corporate governance committee has a formal policy with regard to the consideration of diversity in identifying nominees. When considering nominees, the nominating and corporate governance committee may take into consideration many factors including, among other things, a candidate’s independence, integrity, skills, financial and other expertise, breadth of experience, knowledge about our business or industry and ability to devote adequate time and effort to responsibilities of our board of directors in the context of its existing composition. Through the nomination process, the nominating and corporate governance committee seeks to promote board membership that reflects varied business experience, expertise, viewpoints, personal backgrounds and other characteristics that are expected to contribute to our board of directors’ overall effectiveness. The brief biographical description of each director set forth in Proposal No. 1 below includes the primary individual experience, qualifications, attributes and skills of each of our directors that led to the conclusion that each director should serve as a member of our board of directors at this time.

PROPOSAL NO. 1
ELECTION OF DIRECTORS
Our board of directors currently consists of nine directors and is divided into three classes. Each class serves for three years, with the terms of office of the respective classes expiring in successive years. Directors in Class I will stand for election at the Annual Meeting. The terms of office of directors in Class II and Class III do not expire until the annual meetings of stockholders held in 2026 and 2027, respectively. At the recommendation of our nominating and corporate governance committee, our board of directors proposes that each of the two Class I nominees named below, each of whom is currently serving as a director in Class I, be elected as a Class I director for a three-year term expiring at the 2028 annual meeting of stockholders and until such director’s successor is duly elected and qualified or until such director’s earlier death, resignation, disqualification, or removal. Each director will be elected by a plurality of the votes cast, which means that the two individuals nominated for election to our board of directors at the Annual Meeting receiving the highest number of “FOR” votes will be elected.
Shares represented by proxies will be voted “FOR” the election of each of the two nominees named below, unless the proxy is marked to withhold authority to so vote. If any nominee for any reason is unable to serve or for good cause will not serve, the proxies may be voted for such substitute nominee as the proxy holder might determine. Each nominee has consented to being named in this Proxy Statement and to serve if elected. Proxies may not be voted for more than two directors. Stockholders may not cumulate votes for the election of directors.
Nominees to Our Board of Directors

The ratification of the selection of PwC as our independent registered public accounting firm for the year ending December 31, 2025 requires the affirmative vote of a majority of the voting power of the shares present or represented by proxy at the Annual Meeting.

We expect representatives of PwC to be present at the Annual Meeting and they will be given an opportunity to make a statement at the Annual Meeting if they desire to do so, and will be available to respond to appropriate questions. We do not expect representatives of Ernst & Young LLP (“EY”), our former independent registered public accounting firm, to be present at the Annual Meeting and, therefore, they will not make a statement or address questions.

Changes in Independent Registered Public Accounting Firm
On November 10, 2023, our audit committee dismissed EY as our independent registered public accounting firm. The dismissal was not related to any disagreements with EY on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure. The decision to dismiss EY as our independent registered public accounting firm was at the direction of and approved by our audit committee.
Other than as described below, the reports of EY on our consolidated financial statements as of and for the fiscal years ended December 31, 2022 and December 31, 2021 and the subsequent interim period through November 10, 2023, did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.
During the fiscal years ended December 31, 2022 and 2021 and the subsequent interim period through November 10, 2023, there were (i) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K between the Company and EY on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, any of which, if not resolved to EY’s satisfaction, would have caused EY to make reference thereto in their reports, and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K.
We previously provided EY with a copy of the above disclosures as included in our Form 8-K filed with the SEC on November 15, 2023, and requested EY to furnish us with a letter addressed to the SEC stating whether EY agreed with the statements made by us in response to Item 304(a) of Regulation S-K and, if not, stating the respects in which it does not agree. A copy of EY’s letter, dated November 15, 2023, is attached as Exhibit 16.1 to that Form 8-K, and is incorporated herein by reference.
On November 15, 2023, our audit committee approved the engagement of PwC as our independent registered public accounting firm for the fiscal year ended December 31, 2023. During our two most recent fiscal years ended December 31, 2022 and 2021 and the subsequent interim period through November 10, 2023, neither we nor anyone acting on our behalf consulted with PwC regarding any of the matters described in Items 304(a)(2)(i) and (ii) of Regulation S-K.
Required Vote
Ratification of the appointment of PwC as our independent registered public accounting firm for the fiscal year ending December 31, 2025 requires the affirmative “FOR” vote of a majority of the voting power of the shares present virtually or represented by proxy at the Annual Meeting and entitled to vote on the proposal and are voted for or against the proposal.

PROPOSAL NO. 3
VOTE ON THE COMPENSATION OF OUR
NAMED EXECUTIVE OFFICERS
In accordance with the rules of the SEC, we are providing stockholders with an opportunity to make a non-binding, advisory vote on the compensation of our named executive officers. This non-binding advisory vote is commonly referred to as a “say on pay” vote and gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific item of compensation or any specific named executive officer, but rather the overall compensation of all of our named executive officers and the philosophy, policies, and practices described in this Proxy Statement.
Stockholders are urged to read the section titled “Executive Compensation,” which discusses how our executive compensation policies and procedures implement our compensation philosophy and contains tabular information and narrative discussion about the compensation of our named executive officers. Our compensation committee and board of directors believe that these policies and procedures are effective in implementing our compensation philosophy and in achieving our goals. Accordingly, we ask our stockholders to vote “FOR” the following resolution at the Annual Meeting:
“RESOLVED, that our stockholders approve, on a non-binding advisory basis, the compensation of the Named Executive Officers, as disclosed in the Proxy Statement pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and narrative discussion and the other related disclosures.”
As an advisory vote, this proposal is not binding. However, our board of directors and compensation committee, which are responsible for designing and administering our executive compensation program, value the opinions expressed by stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our named executive officers.
Required Vote
The approval, on an advisory basis, of the compensation of our named executive officers will be obtained if the number of votes “FOR” the proposal at the Annual Meeting exceeds the number of votes “AGAINST” the proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.
OUR BOARD RECOMMENDS A VOTE “FOR” THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

EXECUTIVE COMPENSATION
Compensation Discussion & Analysis
Overview
This Compensation Discussion and Analysis section discusses the principles and practices that guide our executive compensation program. We refer to the following four executive officers as our “named executive officers” (“NEOs”) during the year ended December 31, 2024, each of whose compensation is set forth in the Summary Compensation Table and the other compensation tables included in this Proxy Statement.
Jeremy Bender, Ph.D., M.B.A., our Chief Executive Officer and President
Charles York, II, M.B.A., our Chief Operating Officer and Chief Financial Officer
Samuel Blackman, M.D., Ph.D, our former Co-Founder and Head of Research and Development;(1) and
Adam Dubow, our General Counsel, Chief Compliance Officer and Secretary
(1)
Dr. Blackman retired from the Company effective January 3, 2025 and is no longer considered an executive officer of the Company.
Business Highlights
During 2024, we achieved several important business milestones, including but not limited to, the following:

31

TABLE OF CONTENTS

Compensation Highlights
Our executive compensation program aligns with our strategy and with stockholder interests in three significant respects.
Pay is aligned with performance. Direct compensation for the NEOs has three components: salary; an annual cash bonus opportunity tied to performance against prescribed financial, operational, and strategic goals; and equity in the form of a mix of stock options and restricted stock unit awards (“RSUs”), the value of which hinges on sustained stock price performance.
Most compensation is variable and at risk. The vast majority of target total direct compensation for our NEOs depends on either company performance or stock price. Approximately 90% of target compensation for the Chief Executive Officer (“CEO”), and 84% of target compensation for the other NEOs (on average), is variable and at risk.
Compensation packages are competitive. We provide competitive base salaries and meaningful short- and long-term incentive opportunities to support our retention objectives and to tie compensation to Day One’s stock price and achievement of Day One’s financial, strategic, and operational goals.

*
Pay mix is calculated based on incentive pay opportunities at target.
Compensation Philosophy and Objectives
The objective of our compensation program is to enable us to hire, reward, and retain the world-class talent that we need to execute our strategy and successfully pursue our mission of developing new medicines for people with life-threatening diseases. Our short- and long-term incentive compensation programs are tied to performance and stock price because we believe that consistent and strong results should lead to higher compensation.
As we continue to grow, the Compensation Committee of our board of directors (the “Compensation Committee”) will evaluate our compensation philosophy and objectives regularly to confirm that our program continues to appropriately encourage, motivate, and reward our NEOs.
32

TABLE OF CONTENTS

Executive Compensation Practices
Our executive compensation policies and practices reinforce our long-term, performance-based mindset and our belief that our executives should be rewarded for the success they help create. Our key policies and practices are summarized below.

33

TABLE OF CONTENTS


How We Determine Compensation
Role of the Compensation Committee
Our Compensation Committee acts on behalf of the board of directors in overseeing the compensation arrangements for our executive officers, including our NEOs. This includes reviewing our compensation programs, assessing our compensation risk profile, establishing our compensation peer group, and reviewing our compensation structure and pay mix to ensure alignment with our compensation philosophy and objectives.
Our Compensation Committee reviews the target total direct compensation opportunities for our executive officers, including our NEOs, on at least an annual basis to determine if any adjustments are needed or appropriate.
34

TABLE OF CONTENTS

In reviewing and ultimately approving the compensation of all of our executive officers, the Compensation Committee takes a well-rounded approach that considers a number of factors, including:

These factors provide a framework for decision-making regarding compensation opportunities and final compensation determinations for each NEO. The factors are not assigned specific weights, and no single factor is determinative. Rather, the Compensation Committee members arrive at compensation decisions after considering the relevant factors in light of their individual experience, business judgment, and knowledge of the company, each NEO, and the competitive market.
Role of Company Management and the Chief Executive Officer
In performing its responsibilities, the Compensation Committee consults with members of our management, including our CEO, Chief People Officer, Chief Financial Officer and General Counsel. Management assists our Compensation Committee by providing information on corporate and individual performance, market compensation data, and management’s perspective on compensation matters. Our Compensation Committee solicits and reviews our CEO’s recommendations and viewpoints with respect to adjustments to salary and incentive opportunities, program structures, and other compensation-related matters for our executive officers, other than with respect to the CEO’s own compensation. Our Compensation Committee considers these recommendations as one factor in determining the compensation of our executive officers, but ultimately is responsible for making all compensation decisions. Our CEO is not present during any deliberations or decision-making regarding his compensation.
Role of the Compensation Consultant
To help it carry out its responsibilities, the Compensation Committee retained Compensia Inc. (“Compensia”), a nationally recognized compensation consulting firm, to serve as its independent compensation consultant. Compensia supports the Compensation Committee in its review and oversight of our executive compensation programs. Compensia does not make specific compensation-related recommendations. Instead, the firm uses competitive market data to provide compensation ranges, taking into consideration our compensation peer group and compensation philosophy, for the Compensation Committee to consider. Representatives from Compensia attend certain Compensation Committee meetings, executive sessions, and preparatory meetings with the Compensation Committee chair and certain members of our management team, as requested by the Compensation Committee. Compensia also advises our Compensation Committee on public disclosures relating to our executive compensation programs.
The Compensation Committee has assessed, and periodically confirms, the necessary criteria and has determined that the engagement of Compensia does not raise any conflicts of interest or other similar concerns. Compensia reports directly to our Compensation Committee and does not provide any non-compensation-related services to the Compensation Committee or Day One.
35

TABLE OF CONTENTS

Use of Market Data
The Compensation Committee reviews and considers the compensation levels and practices of a group of peer companies for purposes of assessing the competitive market positioning of our executive compensation program. This peer group consists primarily of biotechnology companies that are similar to us in terms of location, industry, size, market capitalization, and FDA Phase. The Compensation Committee reviews the peer group at least annually with Compensia to account for any year-over-year changes to our business and the businesses of our peer companies.
In developing the 2024 compensation peer group, in consultation with Compensia, we considered the criteria outlined below to identify comparable U.S.-based publicly traded peer companies. In September 2023 the Compensation Committee reviewed the current peer group constituents with Compensia to ensure continued alignment with our business direction and financial profile. Following this review, the Compensation Committee approved the 2024 peer group shown below.

1
The following companies were removed from the 2023 peer group for purposes of 2024 as they were no longer considered to be comparable per the noted criteria primarily due to the lack of a lead asset either pending approval or approved/marketed: Allogene Therapeutics, Arcus Biosciences, Blueprint Medicines, Celldex Therapeuctics, Deciphera Pharmaceuticals, IDEAYA Biosciences, ImmunoGen, Kura Oncology, Mirati Therapeutics, NGM Biopharmaceuticals, Nuvation Bio, PMV Pharmaceuticals, RAPT Therapeutics, Replimune Group, Revolution Medicines, Xencor and Zentalis Pharmaceuticals.

TABLE OF CONTENTS

2024 Executive Compensation Elements
Our executive compensation program consists primarily of the three components described below.

While the Compensation Committee believes this structure is most appropriate for the NEOs at our current stage, as part of its ongoing review of our compensation programs the Compensation Committee will continue to consider whether our incentive structure should change as Day One matures.
Base Salary
Consistent with our long-term oriented philosophy, base salaries represent a small portion of the NEOs’ total direct compensation. In setting base salary amounts, we aim for internal equity among executives in similar roles and with similar performance and tenure. As discussed in “How We Determine Compensation,” we use our annual compensation cycles to adjust salary based on a number of factors, including responsibilities, experience, demonstrated performance, expected future contributions, and applicable market survey and peer data. The 2023 and 2024 base salaries for our NEOs are shown below.

Dr. Blackman retired from the Company effective January 3, 2025 and is no longer considered an executive officer of the Company.
Performance-based Annual Cash Bonus
Our annual incentive plan is structured to promote the achievement of specific and measurable company goals, approved by the Compensation Committee at the beginning of the year, including key objectives in four categories:
pLGG Program;
Finance;
Corporate Development; and
FIREFLY-1
37

TABLE OF CONTENTS

We use the same metrics to determine annual incentives for all executives to promote an enterprise-wide mindset. The Compensation Committee believes each performance metric is a key driver of our success, but to emphasize our focus on long-term value for stockholders, the goals associated with our pLGG program have a collective weight of 60%.
Target Incentive Opportunities
At the beginning of 2024, the Compensation Committee set the following target bonus opportunities for the NEOs:
Executive

Dr. Blackman retired from the Company effective January 3, 2025 and is no longer considered an executive officer of the Company.
Final payouts for each NEO are determined by multiplying the NEO’s target bonus by 100% of the company performance multiplier fixed by the Compensation Committee at the end of the year based on the Company’s achievement in each of the four categories of objectives with discretionary adjustment based on the NEO’s individual performance.
Performance Metrics and Results
Corporate performance goals include stretch goals to incentivize and motivate accelerated achievement of certain objectives. Recognition of stretch achievements ties executive compensation to Company performance, consistent with our pay for performance compensation philosophy.

In a series of meetings in late November and early December 2024, our Compensation Committee and our board of directors reviewed our 2024 corporate goals, taking into account the weighting for each goal and its determination of an achievement rating with respect to each such goal, as well as additional organizational accomplishments in 2024, and approved, based on the aggregate performance level pursuant to such factors, a company performance multiplier of 123% with respect to each executive’s bonus.
Final Annual Incentive Awards
In recognition of their efforts towards our successful achievement of such goals and milestones, the Compensation Committee approved awarding Mr. Bender, Mr. York, Dr. Blackman and Mr. Dubow their respective individual bonuses for 2024 at approximately 123% of each executive’s individual bonus opportunity, taking into account the

determination that we achieved our corporate goals at the 123% level and the individual performance goals at 100% based on the NEO’s individual performance as determined by the CEO (other than himself) and Compensation Committee (for CEO). The 2024 annual bonus payments for the NEOs, which were paid in February 2025, are summarized in the table below.

Long-Term Equity Incentive Awards
Our equity awards serve as a long-term retention tool, encouraging executives to remain with Day One and build value over the long term. The NEOs’ equity compensation is delivered in the form of stock options (50%) and RSUs (50%) allocated based on fair value using 30-day trading average as of December 31, 2023 calculated in accordance with ASC 718. The Compensation Committee selected these equity vehicles and allocations to place an equal emphasis on stock options, which it views as inherently performance-based. In making this determination, it also considered that use of these equity vehicles is generally consistent with compensation practices among our peer group. All equity grants are subject to vesting over a 4-year period providing further retentive value.
Target Equity Grants for the Performance Period Beginning in 2024
In January 2024, the Compensation Committee granted the following equity awards to the NEOs, which fell between the 30th and 80th percentiles of our peer group:
Executive

RSUs

Adam Dubow

$1,535,000
(1)
The number of stock options and RSUs delivered to our NEOs is calculated using the DAWN Nasdaq closing price 30-day trailing average as of December 31, 2023, which differs from the accounting value reported in the Summary Compensation Table.
The exercise price for the stock options is $14.44, the closing price of our common stock on the grant date.
In determining the aggregate number of shares underlying our equity awards, the Compensation Committee considers the dilutive effect of our equity incentive compensation practices and the overall impact that equity awards will have on stockholder value. The Compensation Committee also considered the value of each NEO’s existing equity holdings, including the current economic value and vesting schedules of any unvested equity awards, and the ability of those unvested holdings to satisfy our reward and retention objectives.
Stock Options
The Compensation Committee believes that stock options are effective at motivating executives to pursue our long-term goals because options only have value if our stock price appreciates after the grant date. The options granted in 2024 will vest in equal monthly increments over four years (i.e., 1/48th), beginning in February 2024, so long as the recipient remains in service to Day One, and they will remain exercisable until the tenth anniversary of the grant date. Unvested options will be forfeited if an executive is no longer in service to Day One, but vested options will be exercisable for three months from the date an executive’s service with Day One terminates.
Restricted Stock Units
The Compensation Committee believes that RSUs that vest over several years are effective at retaining talented executives and motivating them to pursue our long-term goals because the value of RSUs is directly tied to our stock price. The RSUs granted in 2024 will vest in equal quarterly increments over four years (i.e., 1/16th), beginning in February 2024, so long as the recipient remains in service to Day One. Each RSU represents a contingent right to receive one share of our common stock following vesting.

TABLE OF CONTENTS

Compensation Practices and Policies
Retirement Savings and Health and Welfare Benefits
We currently maintain a 401(k) retirement savings plan for our employees, including our NEOs, who satisfy certain eligibility requirements. Our NEOs participate in the 401(k) plan on the same terms as other full-time employees. The Internal Revenue Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. We match up to 4% of employees’ contributions to their accounts in the 401(k) plan. Matching contributions are fully vested on the date they are made. We believe that providing a vehicle for tax-deferred retirement savings and making matching contributions adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our NEOs.
We do not provide any non-qualified deferred compensation benefits and do not have any defined benefit pension or supplemental executive retirement plans.
All of our full-time employees, including our NEOs, are eligible to participate in our health and welfare plans, including medical, dental, and vision benefits; medical and dependent care flexible spending accounts; short-term and long-term disability insurance; and life and AD&D insurance.
Perquisites and Other Personal Benefits
We do not view perquisites as important to achieving our compensation objectives. Our NEOs are eligible to participate in our health and welfare benefits on the same basis as all employees. No other perquisites or other personal benefits are provided. In the future, our board of directors or the Compensation Committee may determine that it is necessary or appropriate to provide certain perquisites to one or more NEOs to incentivize or fairly compensate them.
Employment Arrangements
We have entered into offer letters with each of our NEOs. Each offer letter provides for “at will” employment (meaning either Day One or the NEO may terminate the employment relationship at any time with or without cause and with or without notice); sets forth the initial title, base salary, annual incentive opportunity, and equity award for the executive; and summarizes the other terms and conditions applicable to the executive’s employment. Additionally, each of our NEOs has entered into a change in control and severance agreement, described below, and a standard proprietary information and invention assignment agreement.
Severance and Change in Control Benefits
We have entered into change in control and severance agreements with each of our NEOs. These agreements provide for severance benefits in connection with certain qualifying terminations. We believe that providing post-employment compensation arrangements is necessary to achieve our recruitment and retention goals, and to facilitate smooth transitions from Day One when and if appropriate. We have designed our arrangements to provide reasonable continued salary and healthcare coverage in the event of a termination without cause or a resignation for good reason. In addition, we aim to align the NEOs’ interests with those of our stockholders in the event of a change in control of Day One by providing “double-trigger” arrangements that encourage executives to focus on corporate transactions that are in our best interests, regardless of whether those transactions may result in their own job loss. We also condition all severance payments on receipt of a general release of claims to mitigate potential future disputes or litigation arising from an executive’s departure.
For a full description of the terms of these agreements, as well as an estimate of the potential amounts payable under these agreements, see “Potential Payments upon Termination or Change in Control” below.
Insider Trading and Hedging and Pledging Prohibitions
We have adopted an Insider Trading Policy that governs the purchase, sale and/or other dispositions of our securities by directors, officers, employees, consultants and contractors. Our Insider Trading Policy also provides that we will not transact in any of our own securities unless in compliance with U.S. securities laws. We believe that our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the Nasdaq listing standards applicable to us. The policy prohibits the unauthorized disclosure of any material nonpublic information acquired in the workplace and the misuse of material nonpublic information in securities trading. The policy also includes specific provisions which bar covered persons from hedging and pledging our
40

TABLE OF CONTENTS

securities. Additionally, covered persons are barred from engaging in transactions in publicly traded options, such as puts and calls, and other derivative securities with respect to our securities. A copy of our Insider Trading Policy is filed as Exhibit 19.1 to our 2024 Annual Report on Form 10-K.
Policies and Practices Related to the Grant of Certain Equity Awards
Our equity awards, including stock options, are granted in connection with our yearly compensation cycle and regularly scheduled meetings of our Compensation Committee. Our Compensation Committee does not grant equity awards in anticipation of the release of material non-public information. Similarly, we do not time the release of material non-public information based on equity award grant dates.
During fiscal year 2024, (i) none of our named executive officers were awarded stock options with an effective grant date during any period beginning four business days before the filing or furnishing of a Form 10-Q, Form 10-K, or Form 8-K that disclosed material non-public information, and ending one business day after the filing or furnishing of such reports, and (ii) we did not time the disclosure of material non-public information for the purpose of affecting the value of executive compensation.
Compensation Recovery Policy
In December 2023, the Compensation Committee adopted a compensation clawback policy (the “Clawback Policy”) in compliance with the final rules promulgated by the SEC under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, Rule 10D-1 and Nasdaq that provides for the recovery of certain incentive-based compensation in the event we are required to restate our financial statements. The Clawback Policy provides that, in the event of the restatement of any financial reporting required under the securities laws or other similar laws or regulations, our board of directors (or applicable committee thereof) will take such actions as necessary to recover the portion of any incentive-based compensation that was granted, earned or vested based wholly or in part on the attainment of a financial reporting measure which was received by the executive officer that was in excess of the amount that he or she would have received had our financial results been calculated under the restated financial statements; provided that such compensation was paid to or awarded to the executive officer, or which vested (or became eligible to vest) during the Clawback Period. “Clawback Period” under the Clawback Policy is defined as the three completed fiscal years immediately prior to the date on which our board of directors or management determine we are required to (or we are otherwise legally directed to) prepare an accounting restatement and any transition period between the last day of our previous fiscal year end and the first day of our new fiscal year (that results from a change in our fiscal year) within or immediately following such three-year period; provided that any transition period between the last day of our previous fiscal year end and the first day of its new fiscal year that comprises a period of nine to 12 months will be deemed a completed fiscal year.
Accounting and Tax Considerations
Accounting Considerations
The Compensation Committee considers accounting implications when designing compensation plans and arrangements for our NEOs and other employees.
We follow ASC718 for our stock-based compensation awards. ASC 718 requires companies to measure the compensation expense for all share-based awards made to employees and directors, including stock options and RSUs, based on the grant-date fair value of these awards. This calculation is performed for accounting purposes and reported in the compensation tables below, even though our executive officers may never realize any value from their awards.
Tax Considerations
The Compensation Committee generally takes into consideration the tax implications to Day One of our NEO compensation program.
Section 162(m) of the Internal Revenue Code provides that public companies may not take a federal income tax deduction for compensation in excess of $1 million per year paid to certain executives, including current and former NEOs. We believe the Compensation Committee’s ability to provide compensation that is non-deductible allows us to tailor compensation to the needs of our Company and our NEOs and benefits our stockholders.
We do not provide, and have no obligation to provide, any executive officer, including any NEO, with a “gross-up” or other reimbursement payment for any tax liability that he or she might owe because of the application of Section 280G, 4999, or 409A of the Internal Revenue Code.

Potential Payments upon Termination or Change of Control
In May 2021, we adopted arrangements for our executive officers, including our NEOs, that provide for payments and benefits on termination of employment or upon a termination in connection with a change of control (the “Severance Arrangements”).
Under the Severance Arrangements, in the event that Dr. Bender is terminated without “cause” or he resigns for “good reason” outside of the period of three months before or 12 months after a “change of control,” he will be entitled to (i) an amount equal to 12 months of his base salary at the rate in effect immediately prior to such termination, payable in a cash lump-sum, (ii) to the extent Dr. Bender timely elects to receive continued coverage under our group-healthcare plans, we will continue to pay the full amount of his premium payments for such continued coverage for a period ending on the earlier of (x) 12 months following the termination date and (y) the date that he becomes eligible for coverage under another employer’s plans, and (iii) vesting acceleration of his equity awards (including any unvested shares issued upon conversion of any profits interests and excluding any performance-based equity awards) in an amount equal to an additional 12 months of vesting credit. Notwithstanding the foregoing, all such benefits shall be limited to an amount that is not greater than the period of the applicable executive officer’s service to us (e.g., an executive officer who has only been in service to us for two months shall only receive two months of severance, COBRA, and vesting acceleration). Further, in the event that such termination of employment is without “cause” or is due to a resignation for “good reason,” that occurs within three months before or 12 months following a “change of control” of the company, then (i) the amount payable as severance shall be increased to 24 months of Dr. Bender’s base salary at the rate in effect immediately prior to such termination plus 200% of his then-current annual target bonus opportunity, payable in a cash lump-sum, (ii) the period of continued benefit coverage shall be increased to a period of 24 months following the termination date (or, if earlier, until the date that he becomes eligible for coverage under another employer’s plans), and (iii) the vesting acceleration of all equity awards shall be increased to 100% vesting acceleration of each of his then-outstanding equity awards (provided that performance-based awards shall accelerate at the greater of target levels or actual achievement). All such payments and benefits (whether with or apart from a change of control) will be subject to Dr. Bender’s execution of a general release of claims against us.
In the event that either Mr. York or Mr. Dubow is terminated without “cause” or he resigns for “good reason” outside of the period of three months before or 12 months after a “change of control,” he will be entitled to (i) an amount equal to nine months of his base salary at the rate in effect immediately prior to such termination, payable in a cash lump-sum, (ii) to the extent Mr. York or Mr. Dubow timely elects to receive continued coverage under our group-healthcare plans, we will continue to pay the full amount of their premium payments for such continued coverage for a period ending on the earlier of (x) nine months following the termination date and (y) the date that he becomes eligible for coverage under another employer’s plans, and (iii) vesting acceleration of his equity awards (including any unvested shares issued upon conversion of any profits interests and excluding any performance-based
46

TABLE OF CONTENTS

equity awards) in an amount equal to an additional nine months of vesting credit. Notwithstanding the foregoing, all such benefits shall be limited to an amount that is not greater than the period of the applicable executive officer’s service to us (e.g., an executive officer who has only been in service to us for two months shall only receive two months of severance, COBRA, and vesting acceleration). Further, in the event that such termination of employment is without “cause” or is due to a resignation for “good reason,” that occurs within three months before or 12 months following a “change of control” of the company, then (i) the amount payable as severance shall be increased to 18 months of Mr. York’s or Mr. Dubow’s base salary at the rate in effect immediately prior to such termination plus 150% of his then-current annual target bonus opportunity, payable in a cash lump-sum, (ii) the period of continued benefit coverage shall be increased to a period of 18 months following the termination date (or, if earlier, until the date that he becomes eligible for coverage under another employer’s plans), and (iii) the vesting acceleration of all equity awards shall be increased to 100% vesting acceleration of each of his then-outstanding equity awards (provided that performance-based awards shall accelerate at the greater of target levels or actual achievement). All such payments and benefits (whether with or apart from a change of control) will be subject to Mr. York’s or Mr. Dubow’s execution of a general release of claims against us.
The following table provides information concerning the estimated payments and benefits that would be provided in the circumstances described above for each of our NEOs in accordance with the Severance Arrangements in effect on December 31, 2024. Except where otherwise noted, payments and benefits are estimated assuming that the triggering event took place on December 31, 2024, and the price per share of our common stock is $12.67, the closing price on the Nasdaq Global Market as of December 31, 2024, the last business day in the year ended December 31, 2024. There can be no assurance that a triggering event would produce the same or similar results as those estimated below if such event occurs on any other date or at any other price, of if any other assumption used to estimate potential payments and benefits is not correct. Due to the number of factors that affect the nature and amount of any potential payments or benefits, any actual payments and benefits may be different.

TABLE OF CONTENTS

PAY VERSUS PERFORMANCE
As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K (the “PvP Rules”), we are providing tabular compensation and performance disclosure for our fiscal years 2021, 2022, 2023, and 2024 and additional disclosure relative to the relationship between the “Compensation Actually Paid” (“CAP”) set forth in the Pay versus Performance Table and between the Company’s and the Peer Group TSR, in each case over four years. We did not use any financial performance measure to link “compensation actually paid” to our NEOs to our Company performance in the most recently completed fiscal year; accordingly, this disclosure does not present a Company-Selected Measure in the table below. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown. For further information concerning our pay-for-performance philosophy and how we align executive compensation with our performance, refer to the “Compensation Discussion and Analysis” section above.
In the below Pay versus Performance Table, we provide information about compensation of our NEOs for each of the last four fiscal years (the “Covered Years”). Although the PvP Rules require us to disclose “compensation actually paid,” these amounts do not necessarily reflect compensation that our NEOs actually earned in the Covered Years. Instead, “compensation actually paid” reflects a calculation computed in accordance with the PvP Rules, including adjusted values to unvested and vested equity awards during the Covered Years based on either year-end or vesting date stock prices and various accounting valuation assumptions. “Compensation actually paid” generally fluctuates due to stock price performance.

Pursuant to Item 402(v) of Regulation S-K, the comparison assumes $100 was invested in our common stock on May 27, 2021, using the closing stock price on that date. Historic stock price performance is not necessarily indicative of future stock price performance.
(6)
The TSR Peer Group is the Nasdaq Biotechnology Index (NBI). This calculation assumes that $100 was invested in this index on May 27, 2021 (aligned with the period used in footnote #5 above).
Relationship Between Pay and Performance
“Compensation Actually Paid,” as calculated per Item 402(v) of Regulation S-K, reflects cash compensation actually paid as well as changes to the fair values of equity awards during the years shown in the table based on year-end or vesting date stock prices, and various accounting valuation assumptions. Due to how CAP is calculated, the CAP as reported for each year does not reflect the actual amounts earned by our NEOs from their equity awards. CAP generally fluctuates annually due to the change in our stock price from year to year as well as varying levels of actual achievement of performance goals.
Because CAP does not reflect the actual amount earned by our NEOs on their equity compensation, we do not use this measure for understanding how NEO pay aligns with our company performance. For a discussion of how our compensation committee assessed “pay-for-performance” and how our executive compensation program is designed to link executive compensation with the achievement of our financial and strategic objectives as well as stockholder value creation each year, see the “Compensation Discussion and Analysis” section above.
Below are graphs showing the relationship of “Compensation Actually Paid” to our PEO and non-PEO NEOs for our fiscal years 2021, 2022, 2023, and 2024 to (1) TSR of both our common stock and the Nasdaq Biotechnology Index (NBI) and (2) our net income (loss).

TABLE OF CONTENTS



Tabular List of Financial Performance Measures
Given the current life-cycle stage of our Company, specific financial measures do not feature meaningfully in our incentive plan design, which focuses on clinical, regulatory and commercial advancement, business development and overall financial position, as described in the section titled “Compensation Discussion & Analysis.” For the fiscal year ended December 31, 2024, there were no financial performance measures used to link CAP paid to our NEOs to company performance and therefore, no company-selected measure is reported.
CEO Pay Ratio
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to calculate and provide information regarding the relationship between the annual total compensation of our CEO, and the median annual total compensation of our employees (other than our CEO) for the year ended December 31, 2024.
Measurement Date
We identified the median employee using our employee population on December 31, 2024 (including all employees, whether employed on a full-time or part-time basis).
Consistently Applied Compensation Measure
Under the SEC rules, we are required to identify the median employee by use of a “consistently applied compensation measure”, or CACM. We chose a CACM that closely approximates the annual target total direct compensation of our employees. Specifically, we identified the median employee by aggregating for each employee as of December 31, 2024:(1) annual base pay, (2) annual target cash incentive opportunity, (3) the fair market value for equity awards granted during the fiscal year ended December 31, 2024 (as determined at the grant date), and (4) any other items of compensation earned by, or paid to, such employee during 2024 (e.g. retention bonus, spot bonus, 401K match). For employees who joined the Company during 2024, we annualized their compensation values for base pay and annual performance-based cash incentive where applicable.
51

TABLE OF CONTENTS

Methodology and Pay Ratio
After applying our CACM methodology, we identified the median employee. Once the median employee was identified, we calculated the median employee’s annual total direct compensation in accordance with the requirements of the Summary Compensation Table.
Our median employee compensation in 2024 as calculated using Summary Compensation Table requirements was $389,481. Our Chief Executive Officer’s compensation in 2024, as reported in the Summary Compensation Table, was $6,560,577. Therefore, our CEO Pay Ratio for 2024 is approximately 17:1.
We believe this ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Exchange Act. This information is being provided for compliance purposes, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither our compensation committee nor management of the Company used the CEO Pay Ratio measure in making compensation decisions.
Limitations on Liability and Indemnification Matters
Our restated certificate of incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by the DGCL. Consequently, our directors are not personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for:
any breach of the director’s duty of loyalty to us or our stockholders;
any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or
any transaction from which the director derived an improper personal benefit.
Our restated certificate of incorporation and our amended and restated bylaws require us to indemnify our directors and officers to the maximum extent not prohibited by the DGCL and allow us to indemnify other employees and agents as set forth in the DGCL. Subject to certain limitations, our amended and restated bylaws also require us to advance expenses incurred by our directors and officers for the defense of any action for which indemnification is required or permitted, subject to very limited exceptions.
We have entered, and intend to continue to enter, into separate indemnification agreements with our directors, officers, and certain of our other employees. These agreements, among other things, require us to indemnify our directors, officers and key employees for certain expenses, including attorneys’ fees, judgments, penalties, fines and settlement amounts actually incurred by these individuals in any action or proceeding arising out of their service to us or any of our subsidiaries or any other company or enterprise to which these individuals provide services at our request. Subject to certain limitations, our indemnification agreements also require us to advance expenses incurred by our directors, officers and key employees for the defense of any action for which indemnification is required or permitted.
We believe that these provisions in our restated certificate of incorporation, amended and restated bylaws and indemnification agreements are necessary to attract and retain qualified persons such as directors, officers, and key employees. We also maintain directors’ and officers’ liability insurance.
The limitation of liability and indemnification provisions in our restated certificate of incorporation, amended and restated bylaws or in these indemnification agreements may discourage stockholders from bringing a lawsuit against our directors and officers for breaches of their fiduciary duties. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions.
52

TABLE OF CONTENTS

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, executive officers or persons controlling us, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
Rule 10b5-1 Sales Plans
Certain of our directors and executive officers have adopted written plans, known as Rule 10b5-1 plans, in which they have contracted with a broker to buy or sell shares of our common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the director or executive officer when entering into the plan, without further direction from them. The director or executive officer may amend or terminate the plan in specified circumstances.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
Except for the executive officer and director compensation arrangements discussed above under “Executive Compensation” and “Proposal No. 1 Election of Directors-Director Compensation,” respectively, since January 1, 2024, there have been no transactions or series of similar transactions, and there are currently no proposed transactions, to which we were or will be a party in which the amount involved exceeds $120,000 and in which any director, nominee for director, executive officer, beneficial holder of more than 5% of our capital stock or any member of their immediate family or any entity affiliated with any of the foregoing persons had or will have a direct or indirect material interest.
July 2024 Private Placement
On July 30, 2024, we entered into a securities purchase agreement (the “Securities Purchase Agreement”) with certain institutional and accredited investors (the “Investors”), pursuant to which we agreed to sell and issue to the Investors in a private placement (the “Private Placement”) an aggregate of (i) 10,551,718 shares (the “Shares”) of our common stock at a purchase price of $14.50 per share and (ii) 1,517,241 pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to an aggregate of 1,517,241 shares of Common Stock (the “Warrant Shares” and, together with the Shares and the Pre-Funded Warrants, the “Securities”) at a purchase price of $14.4999 per Pre-Funded Warrant. Each Pre-Funded Warrant has an exercise price of $0.0001 per Warrant Share. We received net proceeds of $166.5 million, after deducting placement agent fees, offering costs and other expenses, of which $145.6 million was allocated to the common stock and $20.9 million was allocated to the Pre-Funded Warrants.
In the Private Placement, we sold and issued to AI Day1 LLC Pre-Funded Warrants to purchase up to 827,586 shares of our common stock. Daniel Becker, who serves as Managing Director at Access Biotechnology, the biopharmaceutical investing arm of Access Industries, Inc. and an affiliate of AI Day1 LLC, served as a member of our board of directors from December 2019 through May 23, 2024. Prior to the Private Placement, AI Day1 LLC owned 14.7% of our common stock.
Indemnification Agreements
We have entered into indemnification agreements with each of our directors and executive officers. The indemnification agreements and our restated bylaws require us to indemnify our directors and executive officers to the fullest extent not prohibited by Delaware law. Subject to certain limitations, our restated bylaws also require us to advance expenses incurred by our directors and officers. For more information regarding these agreements, see the section titled “Executive Compensation-Limitation on Liability and Indemnification Matters.”
Review, Approval or Ratification of Transactions with Related Parties
Our written related persons transactions policy provides that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of our common stock, and any members of the immediate family of and any entity affiliated with any of the foregoing persons, are not permitted to enter into a material related person transaction with us without the review and approval of our audit committee, or a committee composed solely of independent directors in the event it is inappropriate for our audit committee to review such transaction due to a conflict of interest. The policy further provides that any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of our common stock or with any of their immediate family members or affiliates in which the amount involved exceeds $120,000 will be presented to our audit committee (or the committee composed solely of independent directors, if applicable) for review, consideration and approval. In approving or rejecting any such proposal, our audit committee (or the committee composed solely of independent directors, if applicable) will consider the relevant facts and circumstances available and deemed relevant to the audit committee (or the committee composed solely of independent directors, if applicable), including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

TABLE OF CONTENTS

receive a single copy of our annual report and proxy materials, including the Notice, unless the affected stockholder has provided contrary instructions. This procedure reduces printing costs and postage fees, and helps protect the environment as well.
This year, a number of brokers with account holders who are our stockholders will be “householding” our annual report and proxy materials, including the Notice. A single Notice and, if applicable, a single set of annual report and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by contacting Broadridge at (866) 540-7095 or writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York, 11717.
Upon written or oral request, we will promptly deliver a separate copy of the Notice and, if applicable, our annual report and other proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the Notice and, if applicable, annual report and other proxy materials, you may write our Secretary at 1800 Sierra Point Parkway, Suite 200, Brisbane, California 94005 telephone number +1 (650) 484-0899.
Any stockholders who share the same address and receive multiple copies of our Notice or annual report and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about householding or our Secretary at the address or telephone number listed above.

Pay vs Performance Disclosure, Table
PAY VERSUS PERFORMANCE
As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K (the “PvP Rules”), we are providing tabular compensation and performance disclosure for our fiscal years 2021, 2022, 2023, and 2024 and additional disclosure relative to the relationship between the “Compensation Actually Paid” (“CAP”) set forth in the Pay versus Performance Table and between the Company’s and the Peer Group TSR, in each case over four years. We did not use any financial performance measure to link “compensation actually paid” to our NEOs to our Company performance in the most recently completed fiscal year; accordingly, this disclosure does not present a Company-Selected Measure in the table below. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown. For further information concerning our pay-for-performance philosophy and how we align executive compensation with our performance, refer to the “Compensation Discussion and Analysis” section above.
In the below Pay versus Performance Table, we provide information about compensation of our NEOs for each of the last four fiscal years (the “Covered Years”). Although the PvP Rules require us to disclose “compensation actually paid,” these amounts do not necessarily reflect compensation that our NEOs actually earned in the Covered Years. Instead, “compensation actually paid” reflects a calculation computed in accordance with the PvP Rules, including adjusted values to unvested and vested equity awards during the Covered Years based on either year-end or vesting date stock prices and various accounting valuation assumptions. “Compensation actually paid” generally fluctuates due to stock price performance.

Tabular List of Financial Performance Measures
Given the current life-cycle stage of our Company, specific financial measures do not feature meaningfully in our incentive plan design, which focuses on clinical, regulatory and commercial advancement, business development and overall financial position, as described in the section titled “Compensation Discussion & Analysis.” For the fiscal year ended December 31, 2024, there were no financial performance measures used to link CAP paid to our NEOs to company performance and therefore, no company-selected measure is reported.
