Dear Stockholder:
You are cordially invited to attend the Annual Meeting of Stockholders (the Annual Meeting) of Erasca, Inc., a Delaware corporation (the Company), at 11:30 a.m. Pacific Time on Friday, June 26, 2026. The Annual Meeting will be a completely virtual meeting, which will be conducted via live webcast.
We have elected to take advantage of Securities and Exchange Commission rules that allow companies to furnish proxy materials to their stockholders by providing access to these documents on the Internet instead of mailing printed copies. Those rules allow a company to provide its stockholders with the information they need, while lowering the costs of delivery and reducing the environmental impact of the Annual Meeting. Most of our stockholders will not receive printed copies of our proxy materials unless requested, but instead will receive a notice with instructions on how they may access and review our proxy materials on the Internet and how they may cast their vote via the Internet. If you would like to receive a printed or e-mail copy of our proxy materials, please follow the instructions for requesting the materials in the Notice of Internet Availability that is being sent to you.
The Notice of Annual Meeting of Stockholders and Proxy Statement on the following pages describe the matters to be presented at the Annual Meeting. Please see the section entitled “How can I attend the Annual Meeting?” of the proxy statement for more information about how to attend the virtual-only meeting.
Whether or not you attend the Annual Meeting online, it is important that your shares be represented and voted at the Annual Meeting. Therefore, I urge you to promptly vote and submit your proxy by phone, via the Internet, or, if you received paper copies of these materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope, which requires no postage if mailed in the United States. If you have received our Notice of Internet Availability of Proxy Materials, the instructions regarding how you can access your proxy materials and vote are contained in that notice. If you have received written proxy materials, the instructions regarding how you can access your proxy materials and vote are contained on the proxy card. If you decide to attend the Annual Meeting, you will be able to vote online, even if you have previously submitted your proxy. If you hold your shares through a bank or broker, you will need a proxy from your bank or broker to vote your shares online at the Annual Meeting.
Thank you for your support.
Sincerely,
| /s/ Jonathan E. Lim |

Householding. The SEC’s rules permit us to deliver a single Internet Notice or set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one Internet Notice or one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the Internet Notice or proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered.

Table of Contents
What is the difference between being a “record holder” and holding shares in “street name”?
If, on the Record Date, your shares were registered directly in your name then you are a stockholder of record.
If, on the Record Date, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting.
Am I entitled to vote if my shares are held in “street name”?
Yes. If your shares are held in street name, these proxy materials, along with instructions on how to vote your shares, are being provided to you by your brokerage firm, bank, dealer or other similar organization. As the beneficial owner, you have the right to direct your brokerage firm, bank, dealer or other similar organization how to vote your shares, and the brokerage firm, bank, dealer or other similar organizations are required to vote your shares in accordance with your instructions. If your shares are held in street name, you may not vote your shares in person at the Annual Meeting, unless you obtain, and present at the Annual Meeting, a legal proxy from your brokerage firm, bank, dealer or other similar organization.
How many shares must be present to hold the Annual Meeting?
A quorum must be present at the Annual Meeting for any business to be conducted. Under Delaware law and our Amended and Restated Bylaws (the Bylaws), the presence at the Annual Meeting online, or by proxy, of the holders of a majority in voting power of the common stock issued and outstanding and entitled to vote, on the Record Date will constitute a quorum for the transaction of business at the Annual Meeting. The inspector of election will determine whether a quorum is present and will tabulate the votes cast at the Annual Meeting.
How can I attend the Annual Meeting?
As noted above, we have decided to hold the Annual Meeting entirely online this year. You may attend the Annual Meeting only if you are a record holder or beneficial owner of our common stock as of the Record Date. If you are a record holder you are entitled to vote at the Annual Meeting. If you hold your shares in street name you must obtain a valid proxy from your brokerage firm, bank, dealer or other similar organization to vote at the Annual Meeting. To attend and participate in the Annual Meeting, you will need the Control Number included in your Internet Notice, your proxy card or on the instructions that accompanied your proxy materials. If your shares are held in “street name,” you should contact your bank or broker to obtain your Control Number or otherwise vote through the bank or broker. To be admitted to the Annual Meeting and vote your shares, you must register to attend the Annual Meeting at www.proxydocs.com/ERAS and provide the Control Number by 2:00 p.m. Pacific Time on June 22, 2026. After completion of your registration, further instructions, including a unique link to access the Annual Meeting, will be emailed to you.
This year’s stockholder question and answer session will include questions submitted in advance of the Annual Meeting. You may submit a question in advance of the meeting as a part of the registration process. Questions pertinent to meeting matters and that are submitted in accordance with our Rules of Conduct for the Annual Meeting will be answered during the Annual Meeting, subject to applicable time constraints. Questions and answers may be grouped by topic and substantially similar questions may be grouped and answered once. In order to promote fairness, efficient use of time and in order to ensure all stockholders are responded to, we will respond to up to two questions from a single stockholder.
What if a quorum is not present at the Annual Meeting?
If a quorum is not present at the scheduled time of the Annual Meeting, (i) the Chairperson of the Annual Meeting or (ii) the holders of a majority of the shares entitled to vote, present at the virtual meeting, or

Table of Contents
represented by proxy, at the virtual meeting are authorized by our Amended and Restated Bylaws to adjourn the Annual Meeting until a quorum is present or represented.
What does it mean if I receive more than one Internet Notice or more than one set of proxy materials?
It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.
How do I vote?
With respect to the election of directors, you may either vote “For” all the nominees to the Board or you may “Withhold” your vote for any nominee you specify. With respect to the ratification of the appointment of KPMG LLP as our independent registered public accounting firm, you may vote “For,” “Against” or “Abstain” from voting.
Stockholders of Record: Shares Registered in Your Name
If you are a stockholder of record, there are several ways for you to vote your shares. Whether or not you plan to attend the virtual Annual Meeting, we urge you to vote by proxy prior to the Annual Meeting to ensure that your vote is counted.
| • | Via the internet: You may vote at www.proxypush.com/ERAS, 24 hours a day, seven days a week, by following the instructions provided in the Internet Notice.

| • | By telephone: You may vote using a touch-tone telephone by calling (866) 648-8133, 24 hours a day, seven days a week.

Beneficial owners: shares registered in the name of a broker, bank or other agent
If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received voting instructions from that organization rather than directly from us. Please check with your bank, broker, or other agent and follow the voting instructions they provide to vote your shares. Generally, you have three options for returning your proxy.
| • | By method listed on voting instruction card: Please refer to your voting instruction card or other information provided by your bank, broker or other agent to determine whether you may vote by telephone or electronically on the Internet, and follow the instructions on the voting instruction card or other information provided by your broker, bank or other agent.

If your bank, broker or other agent does not offer Internet or telephone voting information, please follow the other voting instructions they provide to vote your shares. |

| • | At the virtual Annual Meeting: To vote online during the virtual Annual Meeting, you must obtain a valid proxy from your broker, bank or other agent.

You must also register to attend the Annual Meeting at www.proxydocs.com/ERAS and provide the Control Number included in your Internet Notice, your proxy card or on the instructions that accompanied your proxy materials. After completion of your registration, further instructions, including a unique link to access the Annual Meeting, will be emailed to you. |
Can I change my vote after I submit my proxy?
Yes. If you are a record holder, you may revoke your proxy and change your vote any time before the proxy is voted at the Annual Meeting:
| • | by submitting a duly executed proxy bearing a later date than your prior proxy; |
| • | by granting a subsequent proxy through the Internet or telephone; |
| • | by giving written notice of revocation to the Corporate Secretary of Erasca prior to or at the Annual Meeting; or |
| • | by voting online at the Annual Meeting. |
Your most recent proxy card or telephone or Internet proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy.
If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote virtually at the Annual Meeting by obtaining a legal proxy from your bank or broker and submitting the legal proxy along with your ballot at the Annual Meeting.
Who will count the votes?
A representative from Mediant Communications, Inc. is expected to tabulate the votes and an employee of the Company is expected to be our inspector of election and will certify the votes.
What if I do not specify how my shares are to be voted?
If you are a record holder and you indicate when voting on the Internet or by telephone that you wish to vote as recommended by the Board, then your shares will be voted at the Annual Meeting in accordance with the Board’s recommendation on all matters presented for a vote at the Annual Meeting. Similarly, if you are a record holder and submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board’s recommendations are indicated on page 1 of this proxy statement, along with the description of each proposal in this proxy statement.
If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions, then, the organization that holds your shares may generally vote your shares in their discretion on “routine” matters but cannot vote on “non-routine” matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, that organization will inform the inspector of election that it does not have the authority to vote on that matter with respect to your shares. This is generally referred to as a “broker non-vote.”

Table of Contents
What are broker non-votes and do they count for determining a quorum?
Shares represented by proxies that reflect a broker non-vote will be counted as present for purposes of determining the presence of a quorum. As discussed above, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because (1) the broker has not received voting instructions from the beneficial owner and (2) the broker lacks discretionary voting power to vote those shares on a particular matter. A broker has discretionary power to vote shares without instruction from the beneficial owner on routine matters, such as the ratification of the appointment of KPMG LLP as our independent registered public accounting firm. Thus, broker non-votes are not expected on that proposal. On the other hand, 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. Broker non-votes on the election of directors, which is considered a non-routine matter, will have no effect because they are not considered votes cast, and the three directors that receive the highest number of votes will be elected.
What is an abstention and how will votes withheld and abstentions be treated?
Shares of common stock held by persons attending the Annual Meeting but not voting, and shares represented by proxies that reflect withheld votes or abstentions as to a particular proposal, will be counted as present for purposes of determining the presence of a quorum. A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the ratification of the appointment of KPMG LLP, represents a stockholder’s affirmative choice to decline to vote on a proposal. Votes withheld have no effect on the election of directors, as the three directors that receive the highest number of votes will be elected, and abstentions are not considered to be a vote cast and will have no effect on the ratification of the appointment of KPMG LLP.
How many votes are required for the approval of the proposals to be voted upon and how will abstentions and broker non-votes be treated?
| Proposal |
Votes Required |
Effect of Votes Withheld / Abstentions and Broker Non-Votes | ||
| Proposal 1 – Election of directors | The plurality of the votes cast. This means that the three nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II directors. | Votes withheld and broker non-votes will have no effect. | ||
| Proposal 2 – Ratification of appointment of independent registered public accounting firm | The affirmative vote of a majority of the votes cast for or against the matter. | Abstentions will have no effect. We do not expect any broker non-votes on this proposal. |
Will any other business be conducted at the Annual Meeting?
We currently know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.
Where can I find the voting results of the Annual Meeting?
We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

Proposals To Be Voted On
Proposal 1 – Election of directors
At the Annual Meeting, three Class II directors are to be elected to hold office for a three-year term expiring at the Annual Meeting of Stockholders to be held in 2029 and until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal. Based on the recommendation of the Nominating and Corporate Governance Committee, the Board has nominated Alexander W. Casdin, Julie Hambleton, M.D., and Michael D. Varney, Ph.D.for re-election as Class II directors at the Annual Meeting.
The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the three nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II directors. Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.
Our Amended and Restated Certificate of Incorporation (the Charter) and Bylaws provide that the authorized number of directors shall be fixed from time to time exclusively by resolution adopted by a majority of the Board. We currently have eight authorized directors on our Board. As set forth in our Charter, the Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. The following table summarizes the age, position at the Company, independence, and director class of our directors:
| Name |
Age | Position |
Independent | Director Class(1) | ||||||||||
| Jonathan E. Lim, M.D. |
54 | Chairman of the Board, Chief Executive Officer, and Co-Founder | I | |||||||||||

| (1) | Class II directors are nominated for re-election at the Annual Meeting with a term to expire at the 2029 annual meeting. The terms of Class III directors expire at the 2027 annual meeting. The terms of Class I directors expire at the 2028 annual meeting. |
The division of our Board into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of our Company. Our directors may be removed only for cause and only by the affirmative vote of the holders of at least two-thirds of the voting power of the then-outstanding shares of capital stock entitled to vote in the election of directors.
In the event any of the nominees should become unable to serve, or for good cause will not serve, as a director, it is intended that votes will be cast for a substitute nominee designated by the Board or the Board may elect to reduce its size. The Board has no reason to believe that the nominees named below will be unable to serve if elected. Each of the nominees has consented to being named in this proxy statement and to serve if elected.
All of the persons whose names and biographies appear below are currently serving as our directors. Each of our directors brings to the Board significant leadership experience derived from their professional experience and service as executives or board members of other corporations and/or private equity and venture capital firms. The

process undertaken by the Nominating and Corporate Governance Committee in recommending qualified director candidates is described below under “Board experience and director nomination process.” Certain individual qualifications and skills of our directors that contribute to the Board’s effectiveness as a whole are described in the following paragraphs.
Vote required
The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II Directors. Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.
The Board unanimously recommends a vote FOR the election of the three nominees for Class II directors.

Proposal 2 – Ratification of appointment of independent registered public accounting firm
Our Audit Committee has appointed KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. The Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of our appointment of KPMG LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.
KPMG LLP also served as our independent registered public accounting firm for the fiscal years ended December 31, 2025 and 2024. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit services. A representative of KPMG LLP is expected to attend the Annual Meeting, and to have an opportunity to make a statement and will be available to respond to appropriate questions from stockholders.
In the event that the appointment of KPMG LLP is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent registered public accounting firm for the fiscal year ending December 31, 2027. Even if the appointment of KPMG LLP is ratified, the Audit Committee retains the discretion to appoint a different independent registered public accounting firm at any time if it determines that such a change is in the interest of the Company.
Vote required
This proposal requires the affirmative vote of the holders of a majority in voting power of the votes cast affirmatively or negatively. Abstentions are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of KPMG LLP, we do not expect any broker non-votes in connection with this proposal.
The Board unanimously recommends a vote FOR the ratification of the appointment of KPMG LLP as our independent registered public accounting firm.

Audit Committee pre-approval of audit and non-audit services
The Audit Committee has established a policy that all audit and permissible non-audit services provided by our independent registered public accounting firm will be pre-approved by the Audit Committee, and all such services were pre-approved in accordance with this policy during the fiscal year ended December 31, 2025. These services may include audit services, audit-related services, tax services and other services. The Audit Committee considers whether the provision of each non-audit service is compatible with maintaining the independence of our auditors. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. Our independent registered public accounting firm and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date.
Report of the Audit Committee of the Board
The Audit Committee has reviewed the Company’s audited consolidated financial statements for the fiscal year ended December 31, 2025 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company’s independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by statement on Auditing Standards No. 1301 (Communications with Audit Committees), as adopted by the Public Company Accounting Oversight Board (the PCAOB). The Audit Committee is not employed by the Company, nor does it provide any expert assurance or professional certification regarding the Company’s consolidated financial statements. The Audit Committee relies, without independent verification, on the accuracy and integrity of the information provided, and representations made, by management and the Company’s independent registered public accounting firm.
The Company’s independent registered public accounting firm also provided the Audit Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning

independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from Erasca, Inc. The Audit Committee also considered whether the independent registered public accounting firm’s provision of certain other non-audit related services to the Company is compatible with maintaining such firm’s independence.
Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The Audit Committee and the Board also have recommended, subject to stockholder approval, the ratification of the appointment of KPMG LLP as the Company’s independent registered public accounting firm for 2026.

Corporate Governance
General
The Board has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics and charters for our Nominating and Corporate Governance Committee, Audit Committee and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines and our Code of Business Conduct and Ethics in the “Corporate Governance” section of the “Investors” page of our website located at www.erasca.com, or by writing to our Secretary at our offices at 3115 Merryfield Row, Suite 300, San Diego, California 92121. Please note, however, that the information contained on the website is not incorporated by reference in, or considered part of, this proxy statement.
Director independence
The Board currently consists of eight members. The Board has determined that all of our directors, other than Drs. Lim and Varney, are independent directors in accordance with the listing requirements of the Nasdaq Global Select Market (Nasdaq). The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, the Board has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, the Board reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and relationships as they may relate to us and our management. There are no family relationships among any of our directors or executive officers.
Board experience and director nomination process
Our Nominating and Corporate Governance Committee is responsible for reviewing with the Board, on an annual basis, the appropriate characteristics, skills and experience required for the Board as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current members) for election or appointment, the Nominating and Corporate Governance Committee, in recommending candidates for election, and the Board will take into account many factors, including the following:
| • | personal and professional integrity, strong ethics and values and the ability to make mature business judgments; |
| • | experience in corporate management, such as serving as an officer or former officer of a publicly traded company; |
| • | experience as a board member or executive officer of another publicly traded company; |
| • | experience in finance and accounting and/or executive compensation practices; |
| • | strong leadership skills; |
| • | diversity of expertise and experience in substantive matters pertaining to our business relative to other board members; |
| • | contribution to the range of backgrounds, perspectives, and experiences on the board of directors; |
| • | relevant academic expertise or other proficiency in an area of our business operations; and |
| • | whether the candidate has the time required for preparation, participation and attendance at Board meetings and committee meetings, as applicable. |

Table of Contents
Currently, the Board evaluates each individual in the context of the Board as a whole, with the objective of assembling a group that can best maximize the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas.
Other than the foregoing, there are no stated minimum criteria for director nominees, although the Nominating and Corporate Governance Committee may also consider such other factors as it may deem to be in the best interests of our Company and our stockholders. The Nominating and Corporate Governance Committee does, however, believe it appropriate for at least one member of our Board to meet the criteria for an “audit committee financial expert” as defined by SEC rules, and that a majority of the members of our Board meet the definition of “independent director” under Nasdaq qualification standards. The Nominating and Corporate Governance Committee also believes it is appropriate for our Chief Executive Officer to serve as a member of our Board and as our Chairman.
Identification and evaluation of nominees for directors
The Nominating and Corporate Governance Committee identifies nominees for director by first evaluating the current members of our Board willing to continue in service. Current members with qualifications and skills that are consistent with the Nominating and Corporate Governance Committee’s criteria for Board service and who are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of our Board with that of obtaining a new perspective or expertise.
If any member of our Board does not wish to continue in service or if our Board decides not to re-nominate a member for re-election or if the Board decides to expand the size of the board, the Nominating and Corporate Governance Committee identifies the desired skills and experience of a new nominee in light of the criteria above. The Nominating and Corporate Governance Committee generally polls our Board and members of management for their recommendations. The Nominating and Corporate Governance Committee may also review the composition and qualification of the boards of directors of our competitors and may seek input from industry experts or analysts. The Nominating and Corporate Governance Committee reviews the qualifications, experience and background of the candidates. Final candidates are interviewed by the members of the Nominating and Corporate Governance Committee and by certain of our other independent directors and executive management. In making its determinations, the Nominating and Corporate Governance Committee evaluates each individual in the context of our Board as a whole, with the objective of assembling a group that can best contribute to the success of our Company and represent stockholder interests through the exercise of sound business judgment. After review and deliberation of all feedback and data, the Nominating and Corporate Governance Committee makes its recommendation to our Board.
The Nominating and Corporate Governance Committee evaluates nominees recommended by stockholders in the same manner as it evaluates other nominees. We have not received director candidate recommendations from our stockholders, and we do not have a formal policy regarding consideration of such recommendations. However, any recommendations received from stockholders will be evaluated in the same manner that potential nominees suggested by members of our Board, management or other parties are evaluated.
Under our Bylaws, a stockholder wishing to suggest a candidate for director should write to our Secretary and provide such information about the stockholder and the proposed candidate as is set forth in our Bylaws and as would be required by SEC rules to be included in a proxy statement. In addition, the stockholder must include the consent of the candidate and describe any arrangements or undertakings between the stockholder and the candidate regarding the nomination. In order to give the Nominating and Corporate Governance Committee sufficient time to evaluate a recommended candidate and include the candidate in our proxy statement for the annual meeting, the recommendation should be received by our Corporate Secretary at our principal executive offices in accordance with our procedures detailed in the section below entitled “Stockholder Proposals.”

Communication from stockholders
The Board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Our Secretary is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the directors as he considers appropriate.
Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that our Secretary and Chairman of the Board consider to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications. Stockholders who wish to send communications on any topic to the Board should address such communications to the Board in writing: c/o Secretary, Erasca, Inc., 3115 Merryfield Row, Suite 300, San Diego, California 92121.
Director attendance at annual meetings
Although we do not have a formal policy regarding attendance by members of our Board at our Annual Meeting, we encourage all of our directors to attend.
Board leadership structure
The Board is currently led by our Chairman, Jonathan E. Lim, M.D. The Board recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as we continue to grow. We do not currently separate the roles of Chief Executive Officer and Chairman of the Board. The Board has determined that having an employee director serve as Chairman is in the best interest of our stockholders at this time because combining the roles allows one person to drive strategy and agenda-setting at the board level, as well as maintaining responsibility for executing on that strategy. The Board has concluded that our current leadership structure is appropriate at this time. In 2023, in recognition of the importance of independent oversight over management, the Board created the position of Lead Independent Director. The Lead Independent Director is elected by the independent members of the Board. The Board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.
Lead Independent Director
The responsibilities of the Lead Independent Director, as set forth in our Corporate Governance Guidelines, include, but are not limited to: presiding over all meetings of the Board at which the Chairman of the Board is not present, including any executive sessions of the independent directors; calling separate meetings of the

independent directors, if needed; providing feedback on Board meeting schedules and agendas; acting as the liaison between the independent directors and the Chief Executive Officer and Chairman of the Board; providing the Chairman of the Board with feedback and counsel regarding the Chairman’s interactions with the Board; providing the Chairman of the Board and management with feedback on the quality, quantity, and timeliness of information provided to the Board; responding to stockholder questions that are directed to the Lead Independent Director or the independent directors as a group; and such other functions and responsibilities as requested by the Board from time to time.
Unless otherwise determined by the Board, the Lead Independent Director shall serve for an initial three-year term or, if earlier than the expiration of such three-year term, until such director’s successor has been duly elected and qualified or until such director’s earlier death, resignation or removal. James Bristol, Ph.D., was elected as the Lead Independent Director in July 2023, with a term that ran until the 2025 Annual Meeting. In April 2025, the Board elected Dr. Bristol to an additional three-year term that runs until the 2028 Annual Meeting.
Role of Board in risk oversight process
The Board has responsibility for the oversight of our risk management processes and, either as a whole or through its committees, regularly discusses with management our major risk exposures, their potential impact on our business and the steps we take to manage them. The risk oversight process includes receiving regular reports from Board committees and members of senior management to enable the Board to understand our risk identification, risk management and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, strategic and reputational risk.
The Audit Committee reviews information regarding liquidity and operations, and oversees our management of financial risks. Periodically, the Audit Committee reviews our policies with respect to risk assessment, risk management, loss prevention and regulatory compliance, including with respect to cybersecurity. Oversight by the Audit Committee includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the actions management has taken to limit, monitor or control such exposures. The Compensation Committee is responsible for assessing whether any of our compensation policies or programs has the potential to encourage excessive risk-taking. The Nominating and Corporate Governance Committee manages risks associated with the independence of the Board, corporate disclosure practices, and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered by the Board as a whole.
Board evaluation
Our Corporate Governance Guidelines require the Nominating and Corporate Governance Committee to oversee a periodic assessment by the Board of the Board’s performance. As provided in our Corporate Governance Guidelines, the Nominating and Corporate Governance Committee, acting in consultation with the Board, is responsible for establishing the evaluation criteria and implementing the process for such evaluation.

Narrative disclosure to compensation tables
The primary elements of compensation for our NEOs are base salary, annual performance bonuses and equity awards. The NEOs also participate in employee benefit plans and programs that we offer to our other employees, as described below.
Annual base salary
We pay our NEOs a base salary to compensate them for the satisfactory performance of services rendered to us. The base salary payable to each NEO is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. Base salaries for our NEOs have generally been set at levels deemed necessary to attract and retain individuals with superior talent.
Effective January 1, 2025, Dr. Lim’s annual base salary was increased from $644,600 to $670,400, Dr. Chacko’s annual base salary was increased from $492,100 to $516,700, and Dr. Morris’ annual base salary was increased from $486,500 to $515,000.
24
Table of Contents
In January 2026, each of Drs. Lim, Chacko, and Morris received a base salary increase to $700,000, $540,000, and $536,400, respectively, effective January 1, 2026.
We expect that base salaries for our NEOs will be reviewed periodically by our Compensation Committee, with adjustments expected to be made generally in accordance with the considerations described above and to maintain base salaries at competitive levels.
Bonus compensation
From time to time, our Board or Compensation Committee may approve bonuses for our NEOs based on individual performance, company performance, or as otherwise determined appropriate. Pursuant to their respective employment letter agreements, each NEO has an established target annual bonus amount. For 2025, our NEOs’ target bonuses, expressed as a percentage of annual base salary, were 60% for Dr. Lim and 40% for Drs. Chacko and Morris.
For 2025, annual bonuses were based on corporate performance relative to key corporate objectives tied to clinical and regulatory priorities as well as operational and financial objectives. Following a comprehensive review of our corporate performance relative to these corporate objectives, our compensation committee approved the payment of annual bonuses to our NEOs at 120% of target levels. The annual bonuses paid to our NEOs for 2025 are reflected in the Summary Compensation Table above.
Equity-based incentive awards
Our equity-based incentive awards are designed to align our interests and the interests of our stockholders with those of our employees and consultants, including our NEOs. The Board and compensation committee is responsible for approving equity grants. We typically grant equity awards to new hires upon their commencing employment with us. Generally, our equity awards vest over four years, subject to the employee’s continued employment with us on each vesting date.
In February 2025, we granted Drs. Lim, Chacko, and Morris options to purchase 2,500,000, 800,000, and 780,000 shares of our common stock, respectively, under our 2021 Incentive Award Plan (the 2021 Plan). The options are eligible to vest over a period of four years, with 1/48th of the options vesting on a monthly basis following the vesting commencement date, or February 1, 2025, subject to continuous service through each vesting date. These options are eligible for accelerated vesting on the terms provided in the Severance Plan.
In January 2026, we granted Drs. Lim, Chacko, and Morris options to purchase 2,000,000, 640,000, and 625,000 shares of our common stock, respectively, under our 2021 Plan. The options are eligible to vest over a period of four years, with 1/48th of the options vesting on a monthly basis following the vesting commencement date, or January 29, 2026, subject to continuous service through each vesting date. These options are eligible for accelerated vesting on the terms provided in the Severance Plan.
Other elements of compensation
Perquisites, health, welfare and retirement benefits
Our NEOs are eligible to participate in our employee benefit plans, including our medical, dental, vision, group life, disability and accidental death and dismemberment insurance plans, in each case, on generally the same basis as all of our other employees.
We generally do not provide perquisites or personal benefits to our named executive officers, except in limited circumstances. Our Board may elect to adopt qualified or non-qualified benefit plans in the future if it determines that doing so is in our best interests.
25
Table of Contents
401(k) plan
We maintain a defined contribution employee retirement plan (401(k)) plan for our employees. Our NEOs are eligible to participate in the 401(k) plan on the same basis as our other employees. The 401(k) plan is intended to qualify as a tax-qualified plan under Section 401(a) of the Internal Revenue Code. The 401(k) plan provides that each participant may make pre-tax deferrals from his or her compensation up to the statutory limit, which is $24,500 for calendar year 2026, and other testing limits. Participants that are 50 years or older can also make “catch-up” contributions, which in calendar year 2026 may be up to an additional $8,000 above the statutory limit. The 401(k) plan provides for discretionary matching and profit-sharing contributions. Commencing in 2021, we make safe harbor company contributions of 100% of employee contributions up to 3% of their eligible compensation. Participant contributions are held and invested, pursuant to the participant’s instructions, by the plan’s trustee.
Nonqualified deferred compensation
We do not maintain nonqualified defined contribution plans or other nonqualified deferred compensation plans. Our Board may elect to provide our officers and other employees with non-qualified defined contribution or other nonqualified deferred compensation benefits in the future if it determines that doing so is in our best interests.

Severance plan
In July 2021, our Board adopted our Severance and Change in Control Severance Plan (the Severance Plan) for the benefit of certain employees of our company or any of our parents or subsidiaries as designated by our Compensation Committee (the Covered Employees). The severance benefits under the Severance Plan will supersede any severance benefits otherwise payable under the Covered Employees’ employment offer letters.
The Severance Plan provides assurances of specified severance benefits to Covered Employees whose employment is subject to involuntary termination by us other than for cause (as defined in the Severance Plan) or the Covered Employee resigns for good reason (as defined in the Severance Plan) under the circumstances described in the Severance Plan, including, but not limited to, following a change in control (as defined in the Severance Plan). The severance benefits each Covered Employee could be entitled to receive under the Severance Plan are determined pursuant to each Covered Employee’s classification as the CEO, a Tier 1 Covered Employee, Tier 2 Covered Employee or Tier 3 Covered Employee. Covered Employees are classified as follows:
| • | “CEO” means our Chief Executive Officer. |
| • | “Tier 1 Covered Employee” means an employee of our company who has been designated by our Compensation Committee as eligible to participate under Tier 1 in the Severance Plan. |
| • | “Tier 2 Covered Employee” means an employee of our company who has been designated by our Compensation Committee as eligible to participate under Tier 2 in the Severance Plan. |
| • | “Tier 3 Covered Employee” means an employee of our company who has been designated by our Compensation Committee as eligible to participate under Tier 3 in the Severance Plan. |
Pursuant to the Severance Plan, if, at any time before or after the end of the 12-month period beginning on the date of a change in control, we (or any of our parents or subsidiaries) terminate a Covered Employee’s employment other than for cause (and other than due to death or disability (as defined in the Severance Plan)) or the Covered Employee resigns for good reason, then the Covered Employee will be entitled to receive the following severance benefits, subject to his or her execution of a release of claims and compliance with certain restrictive covenants, including with respect to non-solicitation and non-disparagement:
| • | An amount equal to the Covered Employee’s annualized Base Pay (as defined in the Severance Plan) for 12 months, nine months, six months or six months following termination in the case of the CEO, a Tier 1, Tier 2 or Tier 3 Covered Employee, respectively, paid in a lump sum. |
| • | Company-paid COBRA coverage for 12 months, nine months, six months or six months following termination in the case of the CEO, a Tier 1, Tier 2 or Tier 3 Covered Employee, respectively. |
| • | The accelerated vesting of the equity compensation awards (as defined in the Severance Plan) that would have become vested and exercisable within 12 months, nine months, six months or six months following termination automatically accelerate as of the date of termination in the case of the CEO, a Tier 1, Tier 2 or Tier 3 Covered Employee, respectively. |
Pursuant to the Severance Plan, if, at any time within the 12-month period following a change in control, we (or any of our parents or subsidiaries) terminate a Covered Employee’s employment other than for cause (and other than due to death or disability) or the Covered Employee resigns for Good Reason, then the Covered Employee will be entitled to receive the following severance benefits, subject to his or her execution of a release of claims and compliance with certain restrictive covenants, including with respect to non-solicitation and non-disparagement:
| • | The following aggregate cash amount paid in installments over the following time period: |
| • | In the case of the CEO, the sum of 18 months of annualized base pay and 1.5 times his or her target bonus (as defined in the Severance Plan) paid in a lump sum. |
29
Table of Contents
| • | In the case of a Tier 1 and Tier 2 Covered Employee, the sum of 12 months of annualized base pay and 1.0 times his or her target bonus paid in lump sum. |
| • | In the case of a Tier 3 Covered Employee, the sum of nine months of annualized base pay and the greater of 0.75 times his or her target bonus or a prorated target bonus based on the period of time he or she was employed for the fiscal year in which termination occurs. |
| • | Company-paid COBRA coverage for 18 months, 12 months, 12 months or nine months following termination in the case of the CEO, a Tier 1, Tier 2 or Tier 3 Covered Employee, respectively. |
| • | 100% accelerated vesting of the Covered Employee’s equity compensation awards. |
The severance benefits prescribed by the Severance Plan are subject to a Section 280G better-off cutback provision, which provides that, in the event that the benefits provided to the Covered Employee pursuant to the Severance Plan or otherwise constitute parachute payments with the meaning of Section 280G of the Internal Revenue Code, the Covered Employee’s severance benefits under the Severance Plan will either be delivered in full or reduced to the extent necessary to avoid an excise tax under Section 4999 of the Code, whichever would result in the Covered Employee receiving the largest amount of severance benefits on an after-tax basis.

Director compensation
Our director compensation program is intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors’ interests with those of our stockholders. Directors who are also employees of our company do not receive compensation for their service on the Board. We have reimbursed, and will continue to reimburse, our non-employee directors for their actual out-of-pocket costs and expenses incurred in connection with attending board and committee meetings.
Non-employee director compensation program
The non-employee director compensation program provides for annual retainer fees and/or long-term equity awards for our non-employee directors. Under the non-employee director compensation program in effect for 2025, each non-employee director received an annual retainer of $40,000, and the chair of the Board and/or lead independent director received an additional $30,000. Non-employee directors serving as the chairs of the audit, compensation and nominating and corporate governance committees received additional annual retainers of $15,000, $12,000, and $10,000, respectively. Non-employee directors serving as members of the audit, compensation and nominating and corporate governance committees received additional annual retainers of $7,500, $6,000, and $5,000, respectively. For 2025, the non-employee directors also received initial grants of options to purchase 240,000 shares of our common stock, vesting over three years, upon election to the Board, and thereafter annual grants of options to purchase 120,000 shares of our common stock, vesting on the first to occur of (i) the first anniversary of the grant date or (ii) the next occurring annual meeting of our stockholders. In April 2026, the non-employee director compensation program for 2026 and thereafter was updated to: (i) provide that each new non-employee director is granted an initial equity award with a target grant-date fair value of $650,000, vesting over three years, upon election to the Board; and (ii) provide that each continuing

Table of Contents
non-employee director is granted an annual equity award with a target grant-date fair value of $325,000, vesting on the first to occur of (a) the first anniversary of the grant date or (b) the next occurring annual meeting of our stockholders.
The non-employee director compensation program allows non-employee directors to elect to receive options to purchase shares of our common stock in lieu of receiving all of the cash retainer payable to such director in the next calendar year. Such election is voluntary and irrevocable for the applicable calendar year. In the event a non-employee director timely makes an election, such non-employee director will be granted a number of stock options under the 2021 Plan on the first day of the calendar year in which the cash retainer would otherwise be earned with a value equal to the aggregate dollar value of the cash retainer payable to the non-employee director for such calendar year based on the director’s committee assignments in effect on the last day of the preceding calendar year, as calculated on the grant date in accordance with the Black-Scholes option pricing model (utilizing the same assumptions that we utilized in connection with the most recent stock options we granted prior to the grant date and the average closing price per share of our common stock for the calendar month preceding the grant date). The stock options will vest in twelve monthly installments on the last day of each calendar month following the date of grant.
Compensation under our non-employee director compensation program is subject to the annual limits on non-employee director compensation set forth in the 2021 Plan. Our Board or its authorized committee may modify the non-employee director compensation program from time to time in the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem relevant from time to time, subject to the annual limit on non-employee director compensation set forth in the 2021 Plan (which limits will not apply to any non-employee director that serves in any additional capacity with the company for which he or she receives compensation or any compensation paid to any non-employee director prior to the calendar year following the calendar year in which this offering occurs). As provided in the 2021 Plan, our Board or its authorized committee may make exceptions to this limit for individual non-employee directors in extraordinary circumstances, as the Board or its authorized committee may determine in its discretion, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation or in other compensation decisions involving non-employee directors.

| (1) | Amounts in this column represent the annual retainers to which the non-employee directors were entitled for 2025. Certain of the non-employee directors who were eligible to receive annual retainers elected to receive those annual retainers in the form of stock options, as described above. The number of options to be awarded was determined based on the Black-Scholes option pricing model on January 1, 2025, which resulted in a Black-Scholes value per share of $1.90. The grant date fair value of the options awarded to the non-employee directors, computed in accordance with FASB ASC 718, was lower than the annual retainers otherwise payable to them. See Note 10 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 12, 2026, for a description of the assumptions used in valuing our stock options. |

Security Ownership of Certain Beneficial Owners and Management
The following table and accompanying footnotes set forth certain information with respect to the beneficial ownership of our common stock at April 15, 2026 for:
| • | each of our directors; |
| • | each of our NEOs; |
| • | all of our current directors and executive officers as a group; and |
| • | each person, or group of affiliated persons, who beneficially owned more than 5% of our outstanding common stock. |
We have determined beneficial ownership in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons and entities named in the table below have sole voting and sole investment power with respect to all shares of common stock that they beneficially owned, subject to applicable community property laws.
Applicable percentage ownership is based on 310,923,623 shares of common stock outstanding as of April 15, 2026. In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of that person, we deemed to be outstanding all shares of common stock subject to options, warrants or other rights held by that person or entity that are currently exercisable within 60 days of April 15, 2026. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Erasca, Inc., 3115 Merryfield Row, Suite 300, San Diego, California 92121.

Certain Relationships and Related Person Transactions
The following is a summary of transactions entered into or existing since January 1, 2024 to which we have been a party in which the amount involved exceeded or will exceed $120,000 (or, if less, 1% of the average of our total assets at year-end for the last two completed fiscal years), and in which any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our capital stock or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest, other than equity and other compensation, termination, change in control and other arrangements, which are described under “Executive and Director Compensation.” We also describe below certain other transactions with our directors, executive officers and stockholders.
Stockholders’ agreement
We entered into an amended and restated stockholders’ agreement in April 2020, or the stockholders’ agreement, with the holders of our convertible preferred stock, including entities with which certain of our directors are affiliated. This agreement provides for certain rights relating to the registration of their shares of common stock issuable upon conversion of their convertible preferred stock and certain additional covenants made by us. Except for the registration rights (including the related provisions pursuant to which we have agreed to indemnify the parties to the stockholders’ agreement), all rights under this agreement terminated upon closing of our IPO. The registration rights will terminate five years after the closing of our IPO.
Erasca Foundation
In May 2021, we established the Erasca Foundation to provide support such as direct research grants, hardship grants, patient advocacy, patient education in underserved populations, and funding for other initiatives to positively impact society that align with our mission. Our chief executive officer and certain board members serve as directors of the Erasca Foundation and our chief executive officer, chief financial officer, and chief legal officer are also officers of the Erasca Foundation. In April 2024, we made a donation of $125,000 to the Erasca Foundation.
Indemnification agreements
We have entered into indemnification agreements with each of our directors and executive officers. These agreements, among other things, require us or will require us to indemnify each director (and in certain cases their related venture capital funds) and executive officer to the fullest extent permitted by Delaware law, including indemnification of expenses such as attorneys’ fees, judgments, fines and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in right of us, arising out of the person’s services as a director or executive officer.
Our Charter and Bylaws provide that we will indemnify each of our directors and officers to the fullest extent permitted by the Delaware General Corporation Law. Further, we have entered into indemnification agreements with each of our directors and officers, and we have purchased a policy of directors’ and officers’ liability insurance that insures our directors and officers against the cost of defense, settlement or payment of a judgment under certain circumstances.
Policies and procedures for related person transactions
The Board adopted a written related person transaction policy, setting forth the policies and procedures for the review and approval or ratification of related-person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships in which we were or are to be a participant, where the amount involved exceeds $120,000 (or, if less, 1% of the average of our total assets at year-end for the last two

completed fiscal years) and a related person had or will have a direct or indirect material interest, including, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person. In reviewing and approving any such transactions, our Audit Committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction.

Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2027 Annual Meeting of Stockholders (the 2027 Annual Meeting) pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to our Secretary at our offices at 3115 Merryfield Row, Suite 300, San Diego, California 92121 in writing not later than January 15, 2027, which is 120 days prior to the one-year anniversary of the mailing date of the proxy statement for the Annual Meeting, unless the date of the 2027 Annual Meeting is changed by more than 30 days from the anniversary of our Annual Meeting, in which case the deadline for such proposals will be a reasonable time before we begin to print and send our proxy materials. These proposals must comply with the requirements as to form and substance established by the SEC in Rule 14a-8 of the Exchange Act for such proposals in order to be included in the proxy statement.
Stockholders intending to present a proposal at the 2027 Annual Meeting, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that our Secretary receive written notice from the stockholder of record of their intent to present such proposal or nomination not earlier than the close of business on the 120th day and not later than the close of business on the 90th day prior to the anniversary of the preceding year’s annual meeting. Therefore, the Company must receive notice of such a proposal or nomination for the 2027 Annual Meeting no earlier than the close of business on February 26, 2027, and no later than the close of business on March 28, 2027. The notice must contain the information required by the Bylaws, a copy of which is available upon request to our Secretary. In the event that the date of the 2027 Annual Meeting is more than 30 days before or more than 60 days after June 26, 2027, then our Secretary must receive such written notice not later than the 90th day prior to the 2027 Annual Meeting or, if later, the 10th day following the day on which public disclosure of the date of such annual meeting is first made by the Company. SEC rules permit management to vote proxies in its discretion in certain cases if the stockholder does not comply with this deadline and, in certain other cases, notwithstanding the stockholder’s compliance with this deadline. Stockholders are advised to review our Bylaws which also specify requirements as to the form and content of a stockholder’s notice.
In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 27, 2027.
We intend to file a proxy statement and WHITE proxy card with the SEC in connection with the solicitation of proxies for our 2026 Annual Meeting. Stockholders may obtain our proxy statement (and any amendments and supplements thereto) and other documents as and when filed by the Company with the SEC without charge from the SEC’s website at: www.sec.gov.
We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.
