NOTICE OF ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON JUNE 21, 2018
AT 1:00 P.M. PACIFIC TIME

Dear Stockholder:

        You are cordially invited to attend the annual meeting of stockholders (the "Annual Meeting") of Corvus Pharmaceuticals, Inc., a Delaware corporation ("Corvus", we", "us" or "our"). The Annual Meeting will be held on June 21, 2018, at 1:00 p.m., Pacific Time, at 863 Mitten Road, Suite 102, Burlingame, CA 94010, for the following purposes:

1.

To elect two Class II Directors with terms to expire at the 2021 annual meeting of stockholders;



2.

To ratify the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018; and



3.

To conduct any other business properly brought before the Annual Meeting.

        These items of business are more fully described in the proxy statement accompanying this Notice of Annual Meeting of Stockholders. Only stockholders of record at the close of business on April 25, 2018 (the "Record Date") are entitled to notice of, and to vote at, the Annual Meeting or any adjournment thereof.

        We have elected to use the Internet as our primary means of providing our proxy materials to stockholders. Consequently, stockholders will not receive paper copies of our proxy materials, unless they specifically request them. We will send a Notice of Internet Availability of Proxy Materials on or about April 27, 2018 to our stockholders of record as of the close of business on the Record Date. We are also providing access to our proxy materials over the Internet beginning on or about April 27, 2018. Electronic delivery of our proxy materials will significantly reduce our printing and mailing costs, and the environmental impact of the proxy materials.

        Your vote is very important. Whether or not you attend the Annual Meeting in person, it is important that your shares be represented. You may vote your proxy on the Internet, by phone or by mail in accordance with the instructions in the Notice of Availability of Proxy Materials. Please review the instructions on the proxy card or the information forwarded by your bank, broker or other holder of record regarding each of these voting options.

        Our board of directors recommends that you vote FOR the election of the director nominees named in Proposal 1 of the proxy statement and FOR the ratification of the selection, by the audit committee of our board of directors, of PricewaterhouseCoopers LLP as our independent registered public accounting firm as described in Proposal 2 of the proxy statement.

        On behalf of the board of directors, thank you for your participation in this important annual process.

Even if you have voted by proxy, you may still vote in person if you attend the Annual Meeting. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the Annual Meeting, you must obtain a proxy issued in your name from the record holder.

NOTICE OF ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON JUNE 21, 2018
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 of Corvus Pharmaceuticals, Inc. is soliciting your proxy to vote at our annual meeting of stockholders (the "Annual Meeting") to be held on June 21, 2018 at 1:00 p.m., Pacific Time, at 863 Mitten Road, Suite 102, Burlingame, CA 94010. We invite you to attend the Annual Meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the 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 sent or made available on or about April 27, 2018 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 25, 2018 (the "Record Date") will be entitled to vote at the Annual Meeting. On the Record Date, there were 29,193,690 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 in person at the 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 Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you request and obtain a valid proxy from your broker, bank or other agent.

What am I voting on?

        There are two matters scheduled for a vote:

•

Proposal 1: To elect two Class II Directors with a term to expire at the 2021 annual meeting of stockholders.



•

Proposal 2: To ratify the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2018.

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, 2017, on the Internet at www.envisionreports.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?

        You may either vote "For" or "Withhold" or abstain from voting with respect to the nominee to the board of directors. You may either vote "For" or "Against" or abstain from voting with respect to the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm. 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 in person at the 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 Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote in person if you have already voted by proxy.

1.

To vote in person, come to the Annual Meeting and we will give you a ballot when you arrive.



2.

To vote on the Internet, go to www.envisionreports.com/crvs to complete an electronic proxy card. You will be asked to provide the control number from the Notice and follow the instructions. Your vote must be received by 11:59 p.m., Eastern Time, on June 20, 2018 to be counted.

2

Table of Contents

proxy materials and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.

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 in person at the 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, in person 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 29,193,690 shares of common stock outstanding and entitled to vote.

        Your shares will be counted toward the quorum only if you submit a valid proxy or vote in person at the 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:

1.

Proposal 1: "For" election of 2 nominees for director.



2.

Proposal 2: "For" the ratification of the audit committee's selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2018.

        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

3

Table of Contents

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 is considered non-routine under the applicable rules. If you do not give your broker specific instructions, the broker may not vote your shares on Proposal 1and 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 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, with respect to Proposal 1, "For" votes, "Withhold" votes and broker non-votes and with respect to Proposal 2, "For" votes, "Against" votes and abstentions.

How many votes are needed to approve each proposal?

•

For Proposal 1, the election of two members of the board of directors, the two nominees receiving the highest number of "For" votes will be elected.



•

For Proposal 2, the ratification of the audit committee's selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2018, the proposal must receive a "For" vote from the majority of the votes properly cast either in person or by proxy at the Annual Meeting, excluding abstentions and broker non-votes with respect to the proposal. This is a routine proposal and therefore we do not expect any broker non-votes.

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:

1.

A duly executed proxy card with a later date or time than the previously submitted proxy;



2.

A written notice that you are revoking your proxy to our Secretary, Corvus Pharmaceuticals, Inc., 863 Mitten Road, Suite 102, Burlingame, CA 94010; or



3.

A later-dated vote on the Internet or by phone or a ballot cast in person at the Annual Meeting (simply attending the Annual Meeting will not, by itself, revoke your proxy).

        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 Annual Meeting, by attending the Annual Meeting and voting in person.

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 2018 proxy statement. Any such proposal must be submitted in writing by December 28, 2018, to our Secretary, Corvus Pharmaceuticals, Inc., 863 Mitten Road, Suite 102, Burlingame, CA 94010, the current address of our principal executive offices. If we change the date of our 2018 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 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., 863 Mitten Road, Suite 102, Burlingame, CA 94010, no earlier than February 21, 2019 and no later than the close of business on March 23, 2019, which notice must contain the information specified in our Bylaws. If we change the date of our 2018 annual meeting of stockholders by more than thirty (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 2018 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.

        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., 863 Mitten Road, Suite 102, Burlingame, CA 94010, no earlier than February 21, 2019 and no later than the close of business on March 23, 2019, 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, which notice must contain the information specified in our Bylaws.

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., 863 Mitten Road, Suite 102, Burlingame, CA 94010 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 4 business days following the Annual Meeting.

PROPOSAL 1

ELECTION OF DIRECTORS

        Our board of directors is divided into three classes, designated as Class I, Class II and Class III. Under our Charter, our board of directors 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 of directors. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. 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 of directors currently consists of seven directors, divided into three classes as follows:

•

Class I directors: Richard A. Miller, M.D. and Peter Moldt, Ph.D., whose current terms will expire at the annual meeting of stockholders to be held in 2020;



•

Class II directors: Steve E. Krognes and Scott W. Morrison, whose current terms will expire at the Annual Meeting; and



•

Class III directors: Ian T. Clark, Elisha P. (Terry) Gould III and Peter Thompson, M.D., whose current terms will expire at the annual meeting of stockholders to be held in 2019.

        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 two nominees named below. Directors are elected by a plurality of the votes cast at the meeting.

        Mr. Krognes and Mr. Morrison have been nominated for election at the Annual Meeting to serve as Class II directors. If either Mr. Krognes or Mr. Morrison 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 of directors. Mr. Krognes and Mr. Morrison have agreed to serve if elected. Our management has no reason to believe that Mr. Krognes or Mr. Morrison will be unable to serve. If elected at the Annual Meeting, Mr. Krognes and Mr. Morrison will serve until the earliest of the 2021 annual meeting of stockholders, a successor for either of them is elected and qualified or one or both of their death, resignation or removal.

        The following is a brief biography of Mr. Krognes and Mr. Morrison, 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 of directors to recommend that Mr. Krognes and Mr. Morrison as nominees for director, as of the date of this proxy statement.

        Steve E. Krognes    Mr. Krognes has served as a member of our board of directors since January 2016. Mr. Krognes has served as Chief Financial Officer of Denali Therapeutics Inc., a public biotechnology company, since October 2015. From 2009 to September 2015, Mr. Krognes served as Senior Vice President and Chief Financial Officer at Genentech, Inc., a biotechnology company. From 2004 to 2009, he was Head of Mergers & Acquisitions at Roche Holding AG, a biotechnology company. Mr. Krognes served as Director of Mergers & Acquisitions at Danske Bank A/S, a Danish

bank, from 2002 to 2003. He was a Venture Capitalist with Pylonia Ventures, a Norwegian venture investments company, from 2000 to 2002. From 1996 to 2000, he was a Management Consultant for McKinsey & Company, a consulting firm. Mr. Krognes currently serves as a member of the boards of directors of RLS Global, a Swedish life sciences company, and the California Academy of Sciences, a scientific and educational institution. He was a member of the board of directors and board executive committee of the California Life Sciences Association, an industry organization, from September 2010 to September 2015. Mr. Krognes received a B.S. in Economics from the Wharton School of the University of Pennsylvania and an M.B.A. from Harvard Business School. We believe Mr. Krognes' experience in finance and the biotechnology industry provides him with the qualifications and skills to serve as a member of our board of directors.

        Scott W. Morrison    Mr. Morrison has served as a member of our board of directors since December 2015. From 1996 to December 2015, Mr. Morrison was a Partner with Ernst & Young LLP, a public accounting firm, where he also served as U.S. Life Sciences Leader from 2002 to December 2015. He has served on the board of directors of Audentes Therapeutics, Inc., a public biotechnology company, since December 2015 and on the board of directors of Global Blood Therapeutics, Inc., a public biopharmaceutical company, since January 2016. Since January 2017, Mr. Morrison has served on the board of directors of Symic Bio, Inc., a privately held biotechnology company. Mr. Morrison has held roles on the boards of directors of numerous life sciences industry organizations. Since 1999, he has served on the board of directors of the Biotechnology Institute, a nonprofit organization, where has also served on the audit committee since 2002. Mr. Morrison has previously served on the boards of directors of the Life Sciences Foundation, a biotechnology nonprofit organization, the Bay Area Biosciences Association, a 501(c)(3) organization, and the Emerging Companies Section of the Biotechnology Industry Organization, a trade organization. He received a B.S. in Business Administration from the University of California-Berkeley and is a certified public accountant (inactive). We believe Mr. Morrison's experience in public accounting and the life sciences industry provides him with the qualifications and skills to serve as a member of our board of directors.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF EACH
CLASS II DIRECTOR NOMINEE NAMED ABOVE.

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        The audit committee of our board of directors has selected PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2018 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 for the fiscal years ended December 31, 2017, 2016 and 2015. Representatives of PricewaterhouseCoopers LLP are expected to be present at the 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, 2017 and 2016, respectively, by PricewaterhouseCoopers LLP, our independent registered public accounting firm.

Table of Contents

        All fees described above were approved by our board of directors of the audit committee of the board of directors.

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.

        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 2017 and 2016 were pre-approved by our board of directors 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 in person or represented by proxy at the Annual Meeting and cast on this proposal will be required to ratify the selection of PricewaterhouseCoopers LLP for our fiscal year ending December 31, 2018. 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 OF DIRECTORS RECOMMENDS A VOTE FOR PROPOSAL 2.

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 of directors 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 of directors 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, 2017 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 Statement on Auditing Standards No. 114 (formerly SAS 61), as amended (AICPA, Professional Standards, Vol. 1 AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T. The audit committee also received the written disclosures and the letter from PricewaterhouseCoopers LLP required by the Public Company Accounting Oversight Board Rule 3526 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 of Directors, and the Board of Directors 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, 2017.

        The audit committee and the board of directors have recommended the selection of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm for the year ending December 31, 2018.

Meetings of the Board of Directors, Board and Committee Member Attendance and Annual Meeting Attendance

        The board of directors met four times and acted once by unanimous written consent during the fiscal year ended December 31, 2017. The audit committee met five times, the compensation committee met two times and the nominating and corporate governance committee met one time and acted by unanimous written consent one time. Each member of the board of directors, except Mr. Krognes who attended 50% of the compensation committee meetings held in 2017, attended at least 75% of the aggregate number of meetings of our board of directors, and of the committees on which he 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. All of our directors attended our 2017 annual meeting of stockholders.

Corporate Governance Guidelines

        The board of directors 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 of directors may be viewed at www.corvuspharma.com.

Director Independence

        Our board of directors currently consists of seven (7) members. Our board of directors 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 of directors has made a subjective determination as to each independent director that no relationships exist that, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our board of directors 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.

Table of Contents

        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 of directors with flexibility to combine or separate the positions of chairperson of the board of directors 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 of directors. In that role, Dr. Miller presides over the meetings of our board of directors.

        Our board of directors has concluded that our current leadership structure is appropriate at this time. However, our board of directors 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 of directors 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 of directors 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 of directors does not have a standing risk management committee, but rather administers this oversight function directly through our board of directors as a whole, as well as through various standing committees of our board of directors that address risks inherent in their respective areas of oversight. In particular, our board of directors is responsible for monitoring and assessing 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 of directors has the following standing committees: an audit committee, a compensation committee and a nominating and corporate governance committee. Our board of directors may establish other committees to facilitate the management of our business. The composition and functions of each committee are described below.

Pursuant to their respective agreements, each named executive officer is entitled to severance payments upon the occurrence of certain terminations of employment.

Dr. Miller and Mr. Lea.

        We entered into employment agreements with Dr. Miller and Mr. Lea in November 2014, which were amended and restated in December 2015, setting forth the terms of their employment as our President and Chief Executive Officer and our Chief Financial Officer, respectively. These employment agreements provided for initial base salaries, eligibility for annual discretionary bonuses and the grants of discretionary equity awards, and standard benefit plan participation.

Mr. Hunt

        We entered into an employment agreement with Mr. Hunt in November 2017, setting for the terms of his employment as our Senior Vice President and Chief Business Officer. Mr. Hunt's employment agreement provided for an initial base salary, eligibility for annual discretionary bonuses and the grants of discretionary equity awards, and standard benefit plan participation. Also in November 2014, we entered into a change in control and severance agreement with Mr. Hunt, as described below.

Change in Control and Severance Benefits.

        Pursuant to Dr. Miller's and Mr. Lea's employment agreements, as amended and restated, and Mr. Hunt's change in control and 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 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, 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 vest 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 Mr. Hunt, the number of shares that would have vested in the nine month period following such termination had the executive remained employed or (ii) in the case of Dr. Miller, (a) 100% of the shares subject thereto if the termination occurs prior to the second anniversary of the effective date of the amended and restated agreement or (b) the number of shares that would have vested in the twelve month period following such termination had Dr. Miller remained

employed if the termination occurs after the second anniversary of the effective date of the amended and restated agreement.

        Furthermore, pursuant to Dr. Miller's and Mr. Lea's employment agreements, as amended and restated, and Mr. Hunt's change in control and 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 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, or in the case of Dr. Miller, eighteen, months of his then-existing base salary plus 100%, or, in the case of Dr. Miller, 150%, of his target bonus opportunity; and 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, 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.

        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 and Mr. Lea's employment agreements and Mr. Hunt's change in control and severance agreement:

•

"Cause" means, subject to certain notice requirements and cure rights, the occurrence of any of the following events, as determined by our board of directors or a committee designated by our board, in its sole discretion: the executive's (i) commission of any felony or any crime involving fraud, dishonesty, or moral turpitude under the laws of the United States or any state thereof; attempted commission of, or participation in, a fraud or act of dishonesty against us; intentional, material violation of any contract or agreement with us or of any statutory duty owed to us; (iv) unauthorized use or disclosure of our confidential information or trade secrets; gross misconduct; or, with respect to Dr. Miller's employment agreement, (vi) willful failure to perform his duties and responsibilities to us.



•

"Good Reason" means, subject to certain notice requirements and cure rights, the executive's resignation from all positions he then holds with us if (i) there is a material diminution in his duties and responsibilities with us; provided, however, that a change in title or reporting relationship will not constitute good reason; (ii) there is a material reduction of his base salary; provided, however, that a material reduction in base salary pursuant to a salary reduction program affecting all or substantially all of our employees and that does not adversely affect the executive to a greater extent than other similarly situated employees shall not constitute good reason; or (iii) the executive is required to relocate his primary work location to a facility or location that would increase his one-way commute distance by more than twenty-five (25) miles from his primary work location as of immediately prior to such change.

        Pursuant to their respective agreements, our named executive officers are bound by certain restrictive covenants, including covenants relating to confidentiality and/or assignment of intellectual property rights. In addition, each named executive officer is 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 2017, we matched 100% of each participant's contribution to our 401(k) plan up to a maximum match of $2,000 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 only 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

Securities Authorized for Issuance Under Equity Compensation Plans

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, 2018, 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 that are currently exercisable or exercisable within 60 days of March 31, 2018 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 29,183,481 shares outstanding on March 31, 2018, 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., 863 Mitten Road, Suite 102, Burlingame, CA 94010.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who beneficially own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. Officers, directors and greater than ten percent beneficial owners are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

        To our knowledge, based solely on our review of Forms 3, 4 and 5, and any amendments thereto, furnished to us or written representations that no Form 5 was required, we believe that during the fiscal year ended December 31, 2017, all filing requirements applicable to our executive officers and directors under the Exchange Act were met in a timely manner.

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 or (2) direct your written request to: Secretary, Corvus Pharmaceuticals, Inc., 863 Mitten Road, Suite 102, Burlingame, CA 94010. 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 of directors knows of no other matters that will be presented for consideration at the 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 at the SEC's Public Reference Room at 100 F Street, NE, Washington, D.C. 20549. Information on the operation of the Public Reference Room can be obtained by calling 1-800-SEC-0330. 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, 2017 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
