NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON JUNE 11, 2026

AT 1:00 P.M. PACIFIC TIME

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING PROCEDURES

Why am I receiving these materials?

We sent you a Notice of Availability of Proxy Materials (“Notice”) because the board of directors (the “Board”) of Corvus Pharmaceuticals, Inc. is soliciting your proxy to vote at our annual meeting of stockholders (the “Annual Meeting”) to be held on June 11, 2026 at 1:00 p.m., Pacific Time, virtually at www.meetnow.global/MLFCJA4 at the meeting date and time described in the accompanying proxy statement. You will need to enter the 15 digit control number on your proxy card to submit questions and vote at our virtual Annual Meeting. There will be no physical meeting location. The meeting will only be conducted via an audio webcast. We invite you to attend the virtual Annual Meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the virtual Annual Meeting to vote your shares. Instead, you may vote by proxy over the Internet or by phone by following the instructions provided in the Notice or, if you request printed copies of the proxy materials by mail, you may vote by mail.

The Notice is being made available over the Internet on or about April 24, 2026 to all stockholders of record entitled to vote at the Annual Meeting.

As used in this proxy statement, “Corvus,” the “Company,” “we” or “us” refer to Corvus Pharmaceuticals, Inc., a Delaware corporation.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on April 16, 2026 (the “Record Date”) will be entitled to vote at the Annual Meeting. On the Record Date, there were 84,090,424 shares of our common stock outstanding and entitled to vote.

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, Computershare Trust Company, N.A., then you are a stockholder of record. The Notice will be sent to you by mail directly by us. As a stockholder of record, you may vote at the virtual Annual Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to vote on the Internet or by phone as instructed in the Notice or by proxy by mail by requesting a paper copy of the proxy materials as instructed in the Notice to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Agent

If, on the Record Date, your shares were held in an account at a brokerage firm, bank or other agent, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by such brokerage firm, bank or other agent. The brokerage firm, bank or other agent holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent on how to vote the shares in your account. Your brokerage firm, bank or other agent will not be able

to vote in the election of directors unless they have your voting instructions, so it is very important that you indicate your voting instructions to the institution holding your shares.

You are also invited to attend the virtual Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares at the virtual Annual Meeting unless you request and obtain a valid proxy from your broker, bank or other agent.

What am I voting on?

There are three matters scheduled for a vote:

In addition, you are entitled to vote on any other matters that are properly brought before the Annual Meeting.

How are proxy materials distributed?

Under rules adopted by the Securities and Exchange Commission (“SEC”), we are sending the Notice to our stockholders of record and beneficial owners as of the Record Date. Stockholders will have the ability to access the proxy materials, including this proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, on the Internet at www.investorvote.com/crvs or to request a printed or electronic set of the proxy materials at no charge. Instructions on how to access the proxy materials over the Internet and how to request a printed copy may be found on the Notice and on the website referred to in the Notice, including an option to request paper copies on an ongoing basis.

How do I vote?

Please note that by casting your vote by proxy you are authorizing the individuals listed on the proxy card to vote your shares in accordance with your instructions and in their discretion with respect to any other matter that properly comes before the Annual Meeting or any adjournments or postponements thereof.

The procedures for voting are:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record as of the Record Date, you may vote at the virtual Annual Meeting, vote by proxy over the Internet or by phone by following the instructions provided in the Notice or, if you request printed copies of the proxy materials by mail, you may vote by mail. If your proxy is properly executed in time to be voted at the Annual Meeting, the shares represented by the proxy will be voted in accordance with the instructions you provide. Whether or not you plan to attend the virtual Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend and vote at the virtual Annual Meeting if you have already voted by proxy.

Beneficial Owner: 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 a voting card and voting instructions from that organization rather than from us. Simply follow the instructions to ensure that your vote is counted. To vote at the virtual Annual Meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker, bank or other agent included with the proxy materials, or contact your broker, bank or other agent to request a proxy form.

We provide Internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you owned as of the Record Date.

What is the quorum requirement?

A quorum of stockholders is necessary to take any action at the meeting, other than to adjourn the meeting. The presence, virtually or by proxy duly authorized, of the holders of a majority of the outstanding shares of stock entitled to vote will constitute a quorum. As of the Record Date, there were 84,090,424 shares of common stock outstanding and entitled to vote. Accordingly, 42,045,213 shares must be represented by stockholders present at the Annual Meeting or by proxy to have a quorum.

Your shares will be counted toward the quorum only if you submit a valid proxy or vote at the virtual Annual Meeting. Abstentions and broker non-votes will be counted toward the quorum requirement. If there is no quorum, the chairman of the Annual Meeting or a majority of the votes present at the Annual Meeting may adjourn the Annual Meeting to another date.

What if I return a proxy card but do not make specific choices?

If you are a stockholder of record and you return a proxy card without marking any voting selections, your shares will be voted:

If any other matter is properly presented at the meeting, your proxy (one of the individuals named on your proxy card) will vote your shares using his best judgment.

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, your shares are held by your broker, bank or other agent as your nominee, or in “street name,” and you will need to obtain a proxy form from the organization that holds your shares and follow the instructions included on that form regarding how to instruct the organization to vote your shares. If you do not give instructions to your broker, bank or other agent, it can vote your shares with respect to “discretionary” items but not with respect to “non discretionary” items. Discretionary items are proposals considered routine under the rules of various national securities exchanges, and, in the absence of your voting instructions, your broker, bank or other agent may vote your shares held in street name on such proposals. Non discretionary items are proposals considered non routine under the rules of various national securities exchanges, and, in the absence of your voting instructions, your broker, bank or other agent may not vote your shares held in street name on such proposals and the shares will be treated as broker non votes. Proposal 1 (the election of two directors) and Proposal 3 (non-binding advisory vote to approve the compensation of our named executive officers) are considered non routine under the applicable rules. If you do not give your broker specific instructions, the broker may not vote your shares on Proposals 1 and 3 and your shares will constitute broker non votes which will be counted for purposes of determining whether a quorum exists but will not affect the outcome of these proposals. Proposal 2 (ratification of PricewaterhouseCoopers LLP as our independent registered public accounting firm) involves a matter we believe to be routine and thus, if you do not give instructions to your broker, the broker may vote your shares in its discretion on Proposal 2, and therefore no broker non votes are expected to exist in connection with Proposal 2.

How are votes counted?

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will count:

How many votes are needed to approve each proposal?

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to the Notice and the proxy materials, our directors and employees may also solicit proxies in person, by telephone or by other means of communication. We will not pay our directors and employees any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding the Notice and any other proxy materials to beneficial owners.

What does it mean if I receive more than one Notice?

If you receive more than one Notice, your shares are registered in more than one name or are registered in different accounts. Please vote by proxy according to each Notice to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

Yes, you can revoke your proxy at any time before the final vote at the Annual Meeting. If you are a stockholder of record, you may revoke your proxy in any one of three ways:

If you are a beneficial owner, you may revoke your proxy by submitting new instructions to your broker, bank or other agent, or if you have received a proxy from your broker, bank or other agent giving you the right to vote your shares at the virtual Annual Meeting, by attending and voting at the virtual Annual Meeting.

How do I attend the virtual Annual Meeting?

The live audio webcast of the Annual Meeting will begin promptly at 1:00 p.m. local time. Online access to the audio webcast will open approximately 10 minutes prior to the start of the Annual Meeting to allow time for our stockholders to log in and test their devices’ audio system. We encourage our stockholders to access the meeting in advance of the designated start time.

To attend the Annual Meeting, stockholders will need to log-in to www.meetnow.global/MLFCJA4 and enter the 15 digit code on your Stockholders Meeting Notice.

Can I submit questions at the virtual Annual Meeting?

Stockholders may submit questions and vote during the Annual Meeting at www.meetnow.global/MLFCJA4. To demonstrate proof of stock ownership, you will need to enter the 15 digit control number on your proxy card to submit questions and vote at our Annual Meeting. We intend to answer questions submitted during the meeting that are

Table of Contents

pertinent to the Company and the items being brought before stockholder vote at the Annual Meeting, as time permits, and in accordance with the Rules of Conduct for the Annual Meeting. Answers to any pertinent questions not addressed during the meeting will be posted following the meeting on our website at http://corvuspharma.gcs-web.com. Questions and answers will be grouped by topic and substantially similar questions will be answered only once. To promote fairness, the efficient use of the Company’s resources and ensure all stockholder questions are able to be addressed, we will respond to no more than two questions from a single stockholder.

When are stockholder proposals due for next year’s Annual Meeting?

Pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), some stockholder proposals may be eligible for inclusion in our 2027 proxy statement. Any such proposal must be submitted in writing by December 29, 2026, to our Secretary, Corvus Pharmaceuticals, Inc., 901 Gateway Boulevard, Third Floor, South San Francisco, CA 94080, the current address of our principal executive offices. If we change the date of our 2027 annual meeting of stockholders by more than 30 days from the date of the previous year’s Annual Meeting, the deadline shall be a reasonable time before we begin to print and send our proxy materials. Stockholders interested in submitting such a proposal are advised to contact knowledgeable counsel with regard to the detailed requirements of the applicable securities laws and our amended and restated bylaws (the “Bylaws”). The submission of a stockholder proposal does not guarantee that it will be included in our proxy statement.

Our Bylaws provide that if you wish to submit a proposal that is not to be included in next year’s proxy statement, a timely written notice of a stockholder proposal must be delivered to, or mailed and received by, our Secretary, Corvus Pharmaceuticals, Inc., 901 Gateway Boulevard, Third Floor, South San Francisco, CA 94080, no earlier than February 11, 2027 and no later than the close of business on March 13, 2027, which notice must contain the information specified in our Bylaws. If we change the date of our 2027 annual meeting of stockholders by more than 30 days before, or more than 60 days after, the one-year anniversary of the Annual Meeting, then the written notice of a stockholder proposal that is not intended to be included in our proxy statement must be delivered, or mailed and received, not later than the 90th day prior to our 2027 annual meeting of stockholders or, if later, the 10th day following the day on which certain public disclosure as described in our Bylaws of the meeting date is made. In addition to satisfying the requirements under our Bylaws, to comply with the universal proxy rules under the Exchange Act, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act, no later than April 12, 2027.

What is “householding” and how does it affect me?

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, stockholders who have the same address may receive only one copy of the Notice, unless one or more of these stockholders notifies us that they wish to receive individual copies of the Notice and, if requested, other proxy materials. This process potentially means extra convenience for stockholders and cost savings for the Company.

If you are a beneficial owner of our common stock, once you receive notice from your broker, bank or other agent that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive separate Notices or other proxy materials, please notify your broker, bank or other agent, direct your written request to our Secretary, Corvus Pharmaceuticals, Inc., 901 Gateway Boulevard, Third Floor, South San Francisco, CA 94080 or at (650) 900-4520. Stockholders who currently receive multiple copies of the Notice or other proxy materials at their address and would like to request householding of their communications should contact their broker, bank or other agent.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K filed with the SEC within four business days following the Annual Meeting.

PROPOSAL 1

ELECTION OF DIRECTORS

Our Board is divided into three classes, designated as Class I, Class II and Class III. Under our amended and restated certificate of incorporation (the “Charter”), our Board is authorized to assign its members in office to each class. Each class has a term of three years. Our Charter provides that the authorized number of directors may be changed only by resolution of the Board. Our directors hold office until their successors have been elected and qualified or appointed, or the earlier of their death, resignation or removal.

Our Board currently consists of seven directors, divided into three classes as follows:

At each annual meeting of stockholders, the successors to directors whose terms will then expire will be elected to serve from the time of election and qualification until the third subsequent annual meeting of stockholders.

Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nominees named below. Directors are elected by a plurality of the votes cast at the meeting.

Dr. Miller and Dr. Grais have been nominated for election at the Annual Meeting to serve as Class I directors. If Dr. Miller or Dr. Grais becomes unavailable for election as a result of an unexpected occurrence, shares that would otherwise be voted for them will be voted for the election of a substitute nominee proposed by the nominating and corporate governance committee and nominated by the Board. Dr. Miller and Dr. Grais have agreed to serve if elected. Our management has no reason to believe that Dr. Miller or Dr. Grais will be unable to serve. If elected at the Annual Meeting, Dr. Miller and Dr. Grais will serve until the earliest of the 2029 annual meeting of stockholders, a successor is elected and qualified or his or her death, resignation or removal.

The following is a brief biography of Dr. Miller and Dr. Grais, the nominees for director, and a discussion of their specific experience, qualifications, attributes or skills that led the nominating and corporate governance committee of the Board to recommend Dr. Miller and Dr. Grais as nominees for director, as of the date of this proxy statement.

​

Richard A. Miller, M.D. Dr. Miller has served as our President and Chief Executive Officer since February 2014 and chairman of our Board since January 2014 and co-founded the Company. From April 2012 to October 2014, Dr. Miller was Chairman and Chief Executive Officer of Graphea, Inc., a privately held chemical company, which he founded. Dr. Miller served as Chief Commercialization Officer, Associate Dean and Research Professor in Chemistry at The University of Texas at Austin from September 2010 to December 2011. Dr. Miller founded Principia Biopharma Inc., a privately held biopharmaceutical company, and served as its President and Chief Executive Officer and a member of its board of directors from January 2009 to February 2011. He served as President, Chief Executive Officer and Director of Pharmacyclics, Inc., a public biopharmaceutical company, from 1991, when he co-founded the company, to 2008. At Pharmacyclics, Dr. Miller led the initial discovery and development efforts for ibrutinib. Dr. Miller was a co founder, Vice President and Director of IDEC Pharmaceuticals Corporation, a biotechnology company that merged with Biogen, Inc. in June 2003, where he led research efforts on lymphoma leading to the development of rituximab. Dr. Miller was an Adjunct Clinical Professor of Medicine (Oncology) at Stanford University Medical Center from 1991 to

2023. Dr. Miller received a B.A. in Chemistry from Franklin & Marshall College and an M.D. summa cum laude from the State University of New York Medical School. He is board certified in both Internal Medicine and Medical Oncology. We believe Dr. Miller’s experience as an officer and director of pharmaceutical and biopharmaceutical companies provides him with the qualifications and skills to serve as a member of our Board.

Linda S. Grais, M.D., J.D. Dr. Grais has served as a member of our Board since January 2019. Dr. Grais previously served as President and Chief Executive Officer of Ocera Therapeutics, Inc. from June 2012 to December 2017 and as a member of its board of directors from January 2008 through December 2017. Prior to her employment by Ocera, Dr. Grais served as a managing member at InterWest Partners, a venture capital firm, from May 2005 until February 2011. From July 1998 to July 2003, Dr. Grais was a founder and executive vice president of SGX Pharmaceuticals Inc., a drug discovery company focusing on new treatments for cancer. Prior to that, she was a corporate attorney at Wilson Sonsini Goodrich & Rosati, where she practiced in such areas as venture financings, public offerings and strategic partnerships. Before practicing law, Dr. Grais worked as an assistant clinical professor of Internal Medicine and Critical Care at the University of California, San Francisco. She currently serves on the board of directors of ICON plc, a public contract research organization, Collective Health, a private healthcare services company and Iolyx Therapeutics, Inc., a private biotechnology company. Dr. Grais received a B.A. from Yale University, an M.D. from Yale Medical School and a J.D. from Stanford Law School. We believe Dr. Grais’ experience as an officer and director of pharmaceutical and biopharmaceutical companies provides her with the qualifications and skills to serve as a member of our Board.

CLASS I DIRECTOR NOMINEES NAMED ABOVE.

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee of our Board has selected PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026 and has further directed that management submit the selection of our independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. PricewaterhouseCoopers LLP has audited our financial statements beginning in fiscal year 2014. Representatives of PricewaterhouseCoopers LLP are expected to be present at the virtual Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm. However, the audit committee is submitting the selection of PricewaterhouseCoopers LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the audit committee will reconsider whether or not to retain PricewaterhouseCoopers LLP. Even if the selection is ratified, the audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the committee determines that such a change would be in the best interests of the Company and our stockholders.

Independent Registered Public Accounting Firm Fees And Services

The following table represents aggregate fees billed or to be billed to us for fiscal years ended December 31, 2025 and 2024, respectively, by PricewaterhouseCoopers LLP, our independent registered public accounting firm.

All fees described above were approved by our Board or the audit committee of the Board.

Pre-Approval Policies and Procedures

The audit committee has adopted policies and procedures for the pre-approval of audit and non-audit services provided by our independent registered public accounting firm, PricewaterhouseCoopers LLP. The policy generally requires pre-approval for specified services in the defined categories of audit services, audit-related services and tax services. The pre-approval of services may be delegated to one or more of the audit committee’s members, but the decision must be reported to the full audit committee at its next scheduled meeting.

Table of Contents

The audit committee reviews both audit and non-audit services performed by PricewaterhouseCoopers LLP and the fees charged for such services. Among other things, the audit committee reviews non-audit services proposed to be provided by PricewaterhouseCoopers LLP and pre-approve such services only if they are compatible with maintaining PricewaterhouseCoopers LLP’s status as an independent registered public accounting firm. All services provided by PricewaterhouseCoopers LLP in 2025 and 2024 were pre-approved by our Board or the audit committee after review of each of the services proposed for approval.

The affirmative vote of the holders of a majority of the shares of our common stock present at the virtual Annual Meeting or represented by proxy at the virtual Annual Meeting and cast on this proposal will be required to ratify the selection of PricewaterhouseCoopers LLP for our fiscal year ending December 31, 2026. Abstentions will not be counted as votes cast on this proposal. No broker non-votes are expected to exist in connection with this proposal.

THE BOARD RECOMMENDS A VOTE FOR PROPOSAL 2.

PROPOSAL 3

NON-BINDING, ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Summary

​

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) enables our stockholders to vote to approve, on an advisory, non-binding basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the SEC’s rules, commonly known as a “Say-on-Pay” vote. Accordingly, we are seeking a non-binding, advisory vote to approve the compensation of our named executive officers as described in the “Executive Compensation” section of this proxy statement and the compensation tables and accompanying narrative disclosures that follow.

​

Board Recommendation

​

As described in detail in the sections entitled “Executive Compensation,” our compensation programs are designed to reward, motivate, attract and retain top talent by rewarding performance. We believe that our compensation programs are designed appropriately, emphasizes pay for performance and aligns management’s interests with our stockholders’ interests to support long-term value creation.

​

Accordingly, our Board recommends that stockholders vote “FOR” the following resolution:

​

RESOLVED, that stockholders of Corvus Pharmaceuticals, Inc. (the “Company”) approve, on an advisory non-binding basis, the compensation of the Company’s named executive officers, as disclosed in “Executive Compensation,” compensation tables and the accompanying narrative disclosures of this proxy statement.

​

Approval, on a non-binding, advisory basis, of the compensation of our named executive officers pursuant to the compensation disclosure rules of the SEC, requires the affirmative vote of the holders of a majority of the shares of our common stock present at the virtual Annual Meeting or represented by proxy at the virtual Annual Meeting and cast on this proposal. Abstentions and broker non-votes will not be counted as votes cast on this proposal.

​

While the vote on this resolution is advisory and not binding on us, the compensation committee, or our Board, the compensation committee and our Board values thoughtful input from stockholders and will consider the outcome of the vote on this resolution when considering future executive compensation decisions. Our Board has adopted a policy of providing for advisory votes from stockholders on executive compensation once every year.

​

THE BOARD RECOMMENDS THAT STOCKHOLDERS VOTE, ON A NON-BINDING ADVISORY BASIS, “FOR” THE RESOLUTION TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The material in this report is being furnished and shall not be deemed “filed” with SEC for purposes of Section 18 of the Exchange Act, or otherwise subject to the liability of that section, nor shall the material in this section be deemed to be “soliciting material’ or incorporated by reference in any registration statement or other document filed with the SEC under the Securities Act or the Exchange Act, except as otherwise expressly stated in such filing.

The audit committee of the Board has furnished this report concerning the independent audit of the Company’s financial statements. Each member of the audit committee meets the enhanced independence standards established by the Sarbanes-Oxley Act of 2002 and rulemaking of the SEC and Nasdaq regulations. A copy of the audit committee charter is available on our website at www.corvuspharma.com.

The audit committee’s responsibilities include assisting the Board regarding the oversight of the integrity of the Company’s financial statements, the Company’s compliance with legal and regulatory requirements, the independent registered public accounting firm’s qualifications and independence, and the performance of the independent registered public accounting firm.

In fulfilling its oversight responsibilities, the audit committee reviewed and discussed the Company’s financial statements for the fiscal year ended December 31, 2025 with the Company’s management and PricewaterhouseCoopers LLP. In addition, the audit committee has discussed with PricewaterhouseCoopers LLP, with and without management present, their evaluation of the Company’s internal accounting controls and overall quality of the Company’s financial reporting. The audit committee also discussed with PricewaterhouseCoopers LLP the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. The audit committee also received the written disclosures and the letter from PricewaterhouseCoopers LLP required by the Public Company Accounting Oversight Board Rule 3526 regarding PricewaterhouseCoopers LLP’s communications with the audit committee concerning independence and the audit committee discussed the independence of PricewaterhouseCoopers LLP with that firm.

Based on the audit committee’s review and discussions noted above, the audit committee recommended to the Board, and the Board approved, that the audited 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 have recommended the selection of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2026.

The Board met four times during the fiscal year ended December 31, 2025. The audit committee met five times, the compensation committee met two times and the nominating and corporate governance committee met two times.

14

Table of Contents

Each member of the Board attended at least 75% of the aggregate number of meetings of our Board, and of the committees on which he or she served, held during the last fiscal year. We encourage all of our directors and nominees for director to attend our annual meeting of stockholders; however, attendance is not mandatory. One of our directors attended our 2025 annual meeting of stockholders.

Corporate Governance Guidelines

The Board has documented our governance practices in our corporate governance guidelines to assure that the board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of our stockholders. The corporate governance guidelines set forth certain practices the board will follow with respect to board composition, board committees, board nomination, director qualifications and evaluation of the board and committees. The corporate governance guidelines and the charter for each committee of the Board may be viewed at www.corvuspharma.com.

Director Independence

Our Board currently consists of seven (7) members. Our Board has determined that all of our directors, other than Dr. Miller, qualify as independent directors in accordance with the Nasdaq Global Market (“Nasdaq”) listing requirements. Dr. Miller is not considered independent because he is an employee of the Company. Nasdaq’s independence definition includes a series of objective tests, such as that the director is not, and has not been for at least three (3) years, one of our employees and that neither the director nor any of his or her family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, our Board has made a subjective determination as to each independent director that no relationships exist that, in the opinion of our Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our 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.

As required under Nasdaq rules and regulations, our independent directors meet in regularly scheduled executive sessions at which only independent directors are present.

Leadership Structure of the Board

Our Bylaws and corporate governance guidelines provide our Board with flexibility to combine or separate the positions of chairperson of the Board and Chief Executive Officer and/or the implementation of a lead director in accordance with its determination that utilizing one or the other structure would be in our best interests. Dr. Miller currently serves as the chairperson of our Board. In that role, Dr. Miller presides over the meetings of our Board.

Our Board has concluded that our current leadership structure is appropriate at this time. However, our Board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Role of Board in Risk Oversight Process

Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks with the Board at regular board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks.

Our Board does not have a standing risk management committee, but rather administers this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing

15

Table of Contents

strategic risk exposure. Our audit committee is responsible for overseeing our major financial risk exposures and the steps our management has taken to monitor and control these exposures. The audit committee also monitors compliance with legal and regulatory requirements and considers and approves or disapproves any related person transactions. Our nominating and governance committee monitors the effectiveness of our corporate governance guidelines. Our compensation committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

Committees of the Board of Directors

Our Board has the following standing committees: an audit committee, a compensation committee and a nominating and corporate governance committee. Our Board may establish other committees to facilitate the management of our business. The composition and functions of each committee are described below.

The compensation committee considers those recommendations in determining base salaries, adjustments to base salaries, annual cash bonus program targets and awards and equity awards, if any, for the executive officers and other members of senior management.

The policy prohibits our directors, officers and employees and any entities they control from purchasing financial instruments such as zero-cost collars and forward sale contracts, or otherwise engaging in transactions that hedge, or are designed to hedge, any decrease in the market value of the Company’s equity securities, or that may cause an officer, director or employee to no longer have the same objectives as the Company’s other stockholders. A copy of our Insider Trading Compliance Policy is filed as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2025.

Our Insider Trading Compliance Policy also prohibits covered individuals, including our named executive officers, from (i) making short sales of our securities, (ii) engaging in transactions in puts, calls or other options or derivative instruments related to our equity securities, (iii) engaging in any hedging or similar transaction designed to hedge or offset any change in the market value of our securities and (iv) purchasing our securities on margin or pledging our securities as collateral.

Clawbacks

​

We have adopted a compensation recovery policy as required by Rule 10D-1 under the Exchange Act, and the corresponding listing standards of the Nasdaq, which provides for the mandatory recovery from current and former officers of incentive-based compensation that was erroneously awarded during the three fiscal years preceding the date that the company is required to prepare an accounting restatement, including to correct an error that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The amount required to be recovered is the excess of the amount of incentive-based compensation received over the amount that otherwise would have been received had it been determined based on the restated financial measure.

Employment, Severance and Change in Control Arrangements

We are party to an employment agreement or offer letter with each of Dr. Miller, Mr. Lea and Dr. Jones which sets forth the terms of their employment as our President and Chief Executive Officer, Chief Financial Officer and Senior Vice President, Pharmaceutical Development, respectively. These agreements provided for initial base salaries, eligibility for annual discretionary bonuses and the grants of discretionary equity awards, and standard benefit plan participation.

We are also party to a change in control severance agreement with Dr. Jones. Dr. Miller’s and Mr. Lea’s employment agreements and Dr. Jones’ change in control severance agreement provide for severance benefits in connection with certain terminations of employment.

Change in Control and Severance Benefits.

Pursuant to Dr. Miller’s and Mr. Lea’s employment agreements and Dr. Jones’ change in control severance agreement, in the event that the executive’s employment is terminated by us other than for “cause,” or by the executive for “good reason” (each as defined below) at any time other than during the three month period prior to and twelve month period immediately following a change in control of the Company, the executive is entitled to receive (i) severance payments in an amount equal to nine months or, in the case of Dr. Miller, twelve months, of his then existing base salary; and (ii) continued healthcare coverage for the earlier of nine, or, in the case of Dr. Miller, twelve months, or the date the executive and his dependents, if any, become eligible for healthcare coverage under another employer’s plan(s). In addition, each outstanding equity award that vests subject to the executive’s continued employment will automatically become vested, and, if applicable, all restrictions thereon will lapse, in each case, with respect to (i) in the case of Mr. Lea and Dr. Jones, the number of shares that would have vested in the nine month period following such termination had Mr. Lea and Dr. Jones remained employed or (ii) in the case of Dr. Miller, 100% of the number of shares that would have vested following such termination.

Furthermore, pursuant to Dr. Miller’s and Mr. Lea’s employment agreements, as amended and restated, and Dr. Jones’ change in control severance agreement, in the event that the executive’s employment is terminated by us other than for “cause”, or by the executive for “good reason” (each as defined below) during the three month period prior to and twelve month period immediately following a change in control of the Company, the executive is entitled to receive (i) severance payments in an amount equal to the sum of twelve months or, in the case of Dr. Miller, eighteen months, of his then-existing base salary, specified as $300,000, plus 100% or, in the case of Dr. Miller, 150%, of his target bonus opportunity, payable in a cash lump sum, less applicable withholdings; and (ii) continued healthcare coverage until the earlier of twelve, or in the case of Dr. Miller, eighteen, months following termination, or the date the executive and his dependents, if any, become eligible for healthcare coverage under another employer’s plan(s). In addition, for Mr. Lea and Dr. Jones, each outstanding equity award that vests subject to executive’s continued employment will automatically

become vested, and, if applicable, all restrictions thereon will lapse, in each case, with respect to 100% of the shares subject thereto.

In addition, under Dr. Miller’s employment agreement, each outstanding unvested equity award will automatically become vested and, if applicable, all restrictions thereon will lapse, in each case, with respect to 100% of the shares subject thereto effective upon a change in control of the Company.

Any such severance payments and accelerated vesting are subject to the executive’s timely execution and non-revocation of a general release of claims against us and our affiliates.

With respect to each of Dr. Miller’s and Mr. Lea’s employment agreements and Dr. Jones’ change in control severance agreement:

Pursuant to Dr. Miller’s and Mr. Lea’s employment agreements and a proprietary information agreement entered into by Dr. Jones, each named executive officer is bound by certain restrictive covenants, including covenants relating to confidentiality and/or assignment of intellectual property rights. In addition, they are bound by covenants not to solicit our officers or employees during employment and for a specified period following termination of employment. Each named executive officer is also bound by a covenant not to disparage us or our employees, clients, directors or agents or divert or attempt to divert any of our actual or potential business.

Defined Contribution Plan

We maintain a 401(k) retirement savings plan for the benefit of our employees, including our named executive officers, who satisfy certain eligibility requirements. Under the 401(k) plan, eligible employees may elect to defer a portion of their compensation, within the limits prescribed by the Internal Revenue Code, on a pre-tax or after-tax (Roth) basis through contributions to the 401(k) plan. In 2025, we matched 100% of each participant’s contribution to our 401(k) plan up to a maximum match of $6,000 per participant. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

Perquisites

We provide limited perquisites and other personal benefits to our named executive officers, including the payment of life insurance premiums to the same extent provided to our other employees. We do not view these benefits as a significant component of our executive compensation program.

The Compensation Committee monitors our compensation programs on an annual basis and expects to make modifications as necessary to address any changes in our business or risk profile.

PAY VERSUS PERFORMANCE

Pay Versus Performance Table

The following table sets forth information concerning the compensation provided to our NEOs and certain measures of Company performance in the years ended December 31, 2025, 2024 and 2023, for services to our Company in all capacities. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the fiscal years shown.

Description of Certain Relationships between Information Presented in the Pay versus Performance Table

While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with SEC rules) for a particular

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information regarding the ownership of our common stock as of March 31, 2026, by: (i) each of our directors; (ii) each of our named executive officers as set forth in the summary compensation table above; (iii) all of our executive officers and directors as a group; and (iv) all those known by us to be beneficial owners of more than five percent (5%) of our common stock.

Beneficial ownership is determined in accordance with the rules of the SEC and generally includes voting or investment power with respect to securities. This table is based upon information supplied by officers, directors and principal stockholders and Forms 3, Forms 4, Forms 5 and Schedules 13D and 13G filed with the SEC. Unless otherwise indicated in the footnotes to this table, we believe that each of the stockholders named in the table has sole voting and dispositive power with respect to the shares indicated as beneficially owned, subject to community property laws where applicable. Shares of our common stock subject to options and warrants that are currently exercisable or exercisable within 60 days of March 31, 2026 are deemed to be outstanding and to be beneficially owned by the person holding the options for the purpose of computing the percentage ownership of that person, but are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Applicable percentages are based on 84,090,424 shares outstanding on March 31, 2026, adjusted as required by rules promulgated by the SEC. Unless otherwise indicated, the address of each of the individuals and entities named below is c/o Corvus Pharmaceuticals, Inc., 901 Gateway Boulevard, Third Floor, South San Francisco, CA 94080.

ADDITIONAL INFORMATION

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

Brokers with account holders who are Corvus stockholders may be “householding” our proxy materials. A single proxy statement may 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 notify your broker or the Company that you no longer wish to participate in “householding.”

If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate proxy statement and annual report, you may (1) notify your broker, (2) direct your written request to: Secretary, Corvus Pharmaceuticals, Inc., 901 Gateway Boulevard, Third Floor, South San Francisco, CA 94080, or (3) request from the Company by calling (650) 900-4520. Stockholders who currently receive multiple copies of this proxy statement at their address and would like to request “householding” of their communications should contact their broker. In addition, the Company will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the Form 10-K, proxy statement, Proxy Card or Notice of Availability of Proxy Materials to a stockholder at a shared address to which a single copy of the documents was delivered.

Other Matters

The Board knows of no other matters that will be presented for consideration at the virtual Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

Our website address is www.corvuspharma.com. The information in, or that can be accessed through, our website is not deemed to be incorporated by reference into this proxy statement. Our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and amendments to those reports are available, free of charge, on or through our website as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. The public may read and copy any materials we file with the SEC. The SEC maintains an internet site that contains reports, proxy and information statements and other information regarding our filings at www.sec.gov.

We have filed our Annual Report on Form 10-K for the year ended December 31, 2025 with the SEC. It is available free of charge at the SEC’s web site at www.sec.gov. Upon written request by a Corvus stockholder, we will mail without charge a copy of our Annual Report on Form 10-K, including the financial statements and financial statement schedules, but excluding exhibits to the Annual Report on Form 10-K. Exhibits to the Annual Report on Form 10-K are available upon payment of a reasonable fee, which is limited to our expenses in furnishing the requested exhibit. All requests should be directed to the Secretary, Corvus Pharmaceuticals, Inc., 901 Gateway Boulevard, Third Floor, South San Francisco, CA 94080.
