Information About This Proxy Statement

Why you received this proxy statement. You are viewing or have received these proxy materials because Imago BioSciences, Inc.’s Board of Directors is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the Securities and Exchange Commission (“SEC”) and that is designed to assist you in voting your shares.

Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, the Company is making this proxy statement and its 2021 Annual Report available to its stockholders electronically via the Internet. On or about April 19, 2022, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the “Notice of Internet Availability”) containing instructions on how to access this proxy statement and our 2021 Annual Report and vote online. If you received a Notice of Internet Availability by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Notice of Internet Availability instructs you on how to access and review all of the important information contained in the proxy statement and 2021 Annual Report. The Notice of Internet Availability also instructs you on how you may submit your proxy over the Internet. If you received a Notice of Internet Availability by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained on the Notice of Internet Availability.

Printed Copies of Our Proxy Materials. If you received printed copies of our proxy materials, instructions regarding how you can vote are contained on the proxy card or voting instruction form included with the materials.

Householding. The SEC’s rules permit us to deliver a single set of proxy materials to one address shared by two or more of our stockholders.

To take advantage of this opportunity, we have delivered a single copy of the 2021 Annual Report, proxy statement or Notice of Internet Availability, as applicable, to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the 2021 Annual Report, proxy statement or Notice of Internet Availability, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered.

QUESTIONS AND ANSWERS ABOUT THE 2022 ANNUAL MEETING OF STOCKHOLDERS

Who is entitled to vote at the Annual Meeting?

The Record Date for the Annual Meeting is April 5, 2022. You are entitled to vote at the Annual Meeting only if you were a stockholder of record at the close of business on that date, or if you hold a “legal proxy” from the stockholder of record. Each outstanding share of Common Stock is entitled to one vote for all matters before the Annual Meeting. At the close of business on the Record Date, there were 33,733,683 shares of Common Stock outstanding and entitled to vote at the Annual Meeting, representing 100% of the voting power of our Common Stock. To vote your shares at the Annual Meeting, refer to “How can I attend the Annual Meeting?” below.

How do proxies work?

You may vote by authorizing the persons selected by us as your proxy to vote your shares at the Annual Meeting according to your instructions on the matters discussed herein, and according to their discretion on any other business that may properly come before the Annual Meeting. We have designated two of our executive officers as proxies for the Annual Meeting: Hugh Y. Rienhoff, Jr. and Laura G. Eichorn.

What is the difference between being a “Registered Holder” and holding shares in “street name” as a “Beneficial Holder”?

A “Registered Holder” is a stockholder of the Company, as of the close of business on the Record Date, that holds shares in his or her name. A “Beneficial Holder” is a stockholder of the Company, as of the close of business on the Record Date, that holds shares in “street name” meaning the shares are held in the name of a bank or broker on a person’s behalf.

Am I entitled to vote if I am a Beneficial Holder that holds my shares in “street name” through a bank or broker?

Yes. If your shares are held by a bank or a brokerage firm, you are considered the “beneficial owner” of those shares held in “street name.” If your shares are held in street name, these proxy materials are being provided to you by your bank or brokerage firm, along with a voting instruction form, if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or brokerage firm how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions.

Alternatively, if you wish to attend and vote your shares at the Annual Meeting, you must obtain a “legal proxy” from your bank or brokerage firm (in accordance with the instructions provided to you by them) and then e-mail your “legal proxy” to: dsmsupport@mediantonline.com. The “legal proxy” needs to be received before the Annual Meeting. Please note that in addition to the submission of your “legal proxy” as described in the preceding sentence, in order to attend the Annual Meeting, you will still need to register, in advance of the start of the meeting. See “How can I attend the Annual Meeting?” below.

How many shares must be present to hold the Annual Meeting?

A quorum must be present at the Annual Meeting for any business to be conducted. The holders of a majority in voting power of our stock issued and outstanding and entitled to vote, present in person (virtually) or represented by proxy at the Annual Meeting, shall constitute a quorum.

How can I attend the Annual Meeting?

As part of our effort to maintain a safe and healthy environment for our stockholders, directors and members of management, in light of the COVID-19 pandemic, the Company has decided to hold the Annual Meeting entirely online this year. You may attend and participate in the Annual Meeting by visiting www.proxydocs.com/IMGO

and registering, in advance, using the control number provided to you in your Notice of Internet Availability of Proxy Materials, on your proxy card or on the instructions that accompanied your proxy materials. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting. You must complete your registration in advance of the start time of the meeting in order to be able to attend the Annual Meeting.

Those who wish to vote at the Annual Meeting but are not Registered Holders must also obtain a “legal proxy” from the record holder and e-mail the “legal proxy” to: dsmsupport@mediantonline.com. The “legal proxy” needs to be received before the Annual Meeting.

If you lose your control number or fail to register in advance, you may join the Annual Meeting as a “Guest” but you will not be able to vote, ask questions or access the list of stockholders as of the Record Date. The meeting webcast will begin promptly at 11:30 a.m. Pacific Time (2:30 p.m. Eastern Time). We encourage you to access the Annual Meeting prior to the start time. Online check-in will begin 15 minutes prior to the Annual Meeting at 11:15 a.m., Pacific Time (2:15 p.m. Eastern Time), and you should allow ample time for the check-in procedures.

What if a quorum is not present at the Annual Meeting?

If a quorum is not present at the scheduled time of the Annual Meeting, the chairperson of the Annual Meeting is authorized by our Amended and Restated Bylaws to adjourn the Annual Meeting in the manner provided for in our bylaws, without the vote of stockholders.

What does it mean if I receive more than one Notice of Internet Availability or more than one set of proxy materials?

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Notice of Internet Availability or set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the proxy card or voting instruction form.

How do I vote?

Registered Holders. If you are a Registered Holder, you may vote:

•

by Internet before the Annual Meeting—You can vote over the Internet at www.proxydocs.com/IMGO by following the instructions on the Notice of Internet Availability or proxy card;

•

by Telephone before the Annual Meeting—You can vote by telephone by calling 866-220-2494 and following the instructions on the proxy card;

•

by Mail before the Annual Meeting—You can vote by mail by signing, dating and mailing the proxy card; or

•

by Internet at the Annual Meeting—You will need the control number included on your Notice of Internet Availability or proxy card to, and must register in advance to, attend the Annual Meeting and vote electronically during the Annual Meeting. See “How can I attend the Annual Meeting?” above.

For Registered Holders, internet and telephone voting facilities will be available 24 hours a day until the start of the Annual Meeting.

Whether or not you expect to attend the Annual Meeting online, we urge you to vote your shares as promptly as possible to ensure your representation and the presence of a quorum at the Annual Meeting. If you submit your proxy, you may still decide to attend the Annual Meeting and vote your shares electronically during the Annual Meeting.

Beneficial Holders of Shares Held in “Street Name.” If your shares are held in “street name” through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions in order for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers, together with a deadline for voting prior to the Annual Meeting.

Alternatively, if you wish to attend and vote your shares at the Annual Meeting, you must register in advance and obtain a “legal proxy” from your bank or brokerage firm. See “Am I entitled to vote if I am a Beneficial Holder that holds my shares in ‘street name’ through a bank or broker?” and “How can I attend the Annual Meeting?” above.

Can I change my vote after I submit my proxy?

Yes.

If you are a Registered Holder, you may revoke your proxy and change your vote:

•

by submitting a duly executed proxy bearing a later date;

•

by granting a subsequent proxy through the Internet or by telephone;

•

by giving written notice of revocation to our Corporate Secretary prior to the Annual Meeting; or

•

by voting online at the Annual Meeting (see “How can I attend the Annual Meeting?” above).

Your most recent proxy card or Internet or telephone proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to our Corporate Secretary before your proxy is voted or you vote online at the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank. Alternatively, you may change or revoke your voting instructions by attending the Annual Meeting and voting you shares. To do so, you must register in advance and obtain a “legal proxy” from your bank or brokerage firm. See “Am I entitled to vote if I am a Beneficial Holder that holds my shares in ‘street name’ through a bank or broker?” and “How can I attend the Annual Meeting?” above.

Who will count the votes?

A representative of Mediant Communications, Inc., our Inspector of Election, will tabulate and certify the votes.

What if I do not specify how my shares are to be voted?

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board of Directors. The Board of Directors’ recommendations are indicated on pages 8 and 11 of this proxy statement, as well as with the description of each proposal in this proxy statement.

Will any other business be conducted at the Annual Meeting?

Why hold a virtual meeting?

As part of our effort to maintain a safe and healthy environment for our directors, members of management and stockholders who wish to attend the Annual Meeting, in light of COVID-19, we believe that hosting a virtual

meeting this year is in the best interest of the Company and its stockholders. A virtual meeting also enables increased stockholder attendance and participation because stockholders can participate from any location around the world.

What if during the check-in time or during the Annual Meeting I have technical difficulties or trouble accessing the virtual meeting website?

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting website. If you encounter any difficulties accessing the virtual-only Annual Meeting platform, including any difficulties using your unique link, or voting your shares or submitting questions, you may call the technical support number that will be provided to you in your instructional email.

How many votes are required for the approval of the proposals to be voted upon and how will abstentions and broker non-votes be treated?


Proposal	Votes required	Effect of Votes Withheld / Abstentions and Broker Non-Votes
Proposal 1: Election of Directors	A plurality of the votes cast. This means that the nominee receiving the highest number of affirmative “FOR” votes will be elected as a Class I Director.	Votes withheld and broker non-votes will have no effect.

Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm	The affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes).	Abstentions and broker non-votes, if any, will have no effect.

What is a “vote withheld” and an “abstention” and how will votes withheld and abstentions be treated?

A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the proposal regarding the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm, represents a stockholder’s affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on the election of directors. Abstentions have no effect on the ratification of the appointment of Deloitte & Touche LLP.

What are broker non-votes and do they count for determining a quorum?

Generally, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors. Broker non-votes count for purposes of determining whether a quorum is present.

Where can I find the voting results of the Annual Meeting?

We plan to announce preliminary voting results at the Annual Meeting, and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC after the Annual Meeting.

PROPOSALS TO BE VOTED ON

Proposal 1: Election of Directors

We currently have seven directors on our Board. However, Patrick Heron has not been nominated for re-election, and his Board service will end at the conclusion of the Annual Meeting. The Board has reduced the size of the Board to six directors, effective at the conclusion of the Annual Meeting. At the Annual Meeting, one Class I Director, Dennis Henner, is to be elected to hold office until the Annual Meeting of Stockholders to be held in 2025 and until his successor is elected and qualified or until his earlier death, resignation or removal.

The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the nominee receiving the highest number of affirmative “FOR” votes will be elected as a Class I Director. Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

As set forth in our Amended and Restated Certificate of Incorporation, the Board of Directors is currently divided into three classes, designated as Class I, Class II and Class III, as nearly equal in number as possible and with staggered, three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. The current class structure is as follows: Class I, whose term currently expires at the Annual Meeting and whose subsequent term will expire at the 2025 Annual Meeting of Stockholders; Class II, whose term will expire at the 2023 Annual Meeting of Stockholders; and Class III, whose term will expire at the 2024 Annual Meeting of Stockholders. The current Class I Directors are Dennis Henner and Patrick Heron (Mr. Heron is not nominated for re-election at the Annual Meeting); the current Class II Directors are Robert Baltera and Dina Chaya; and the current Class III Directors are Enoch Kariuki, Hugh Y. Rienhoff, Jr. and Laurie Keating.

The division of our Board of Directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of our Company. Our directors may be removed only for cause by the affirmative vote of the holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting power of all the then outstanding shares of voting stock with the power to vote at the election of directors, subject to the any special rights of any preferred stock.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of Common Stock represented thereby for the election of Dr. Henner as a Class I Director. In the event that Dr. Henner should become unable to serve, or for good cause will not serve, as a director, it is intended that votes will be cast for a substitute nominee designated by the Board of Directors, or the Board may elect to reduce its size. The Board of Directors has no reason to believe that Dr. Henner will be unable to serve if elected. Dr. Henner has consented to being named in this proxy statement and to serve if elected.

Vote required

Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

Recommendation of the Board of Directors

The Board of Directors unanimously recommends a vote FOR the election of Dr. Henner as a Class I Director.

Nominee For Class I Director (term to expire at the 2025 Annual Meeting)

Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit Committee has appointed Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022. Our Board has directed that this appointment be submitted to our stockholders for ratification at the Annual Meeting. Although ratification of our appointment of Deloitte & Touche LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

Deloitte & Touche LLP also served as our independent registered public accounting firm for the fiscal year ended December 31, 2021. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of Deloitte & Touche LLP is expected to attend the 2022 Annual Meeting and to have an opportunity to make a statement and be available to respond to appropriate questions from stockholders.

In the event that the appointment of Deloitte & Touche LLP is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent registered public accounting firm for the fiscal year ending December 31, 2022. Even if the appointment of Deloitte & Touche LLP is ratified, the Audit Committee retains the discretion to appoint a different independent registered public accounting firm at any time if it determines that such a change is in the interest of the Company.

Vote Required

This proposal requires the affirmative vote of the holders of a majority in voting power of the votes cast. Abstentions are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of Deloitte & Touche LLP, we do not expect any broker non-votes in connection with this proposal.

Recommendation of the Board of Directors

The Board of Directors unanimously recommends a vote FOR the Ratification of the Appointment of Deloitte & Touche LLP as our Independent Registered Public Accounting Firm for the fiscal year ending December 31, 2022.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The Audit Committee has reviewed the audited consolidated financial statements of the Company for the fiscal year ended December 31, 2021 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also discussed with the independent registered public accountants the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Securities and Exchange Commission.

The Company’s independent registered public accounting firm also provided the Audit Committee with the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from the Company.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES AND OTHER MATTERS

The following table summarizes the fees of Deloitte & Touche LLP, our independent registered public accounting firm, billed to us for each of the last two fiscal years for audit and other services:


Fee Category	2021		2020
Audit Fees	$	1,086,138	$	775,508
Audit-Related Fees		—		—
Tax Fees		—		—
All Other Fees		—		—
Total Fees	$	1,086,138	$	775,508

Audit Fees

Audit fees consist of all professional services rendered in connection with (a) the audit of our annual consolidated financial statements, (b) the reviews of our quarterly consolidated financial statements, (c) our Registration Statement on Form S-1 related to the initial public offering of our common stock (“IPO”) and (d) consents and review of other documents filed with the SEC.

Audit-Related Fees

Audit-related fees consist of business combination financial due diligence, internal control readiness and professional services rendered in connection with the audit of our 401(k) retirement savings plan. There were no such fees incurred in 2021 or 2020.

Tax Fees

There were no such fees incurred in 2021 or 2020.

All Other Fees

All other fees consist of services not included in the other three categories. There were no such fees incurred in 2021 or 2020.

Audit Committee Pre-Approval Policy and Procedures

The Audit Committee has adopted a policy (the “Pre-Approval Policy”) that sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by the independent registered public accounting firm may be pre-approved. The Pre-Approval Policy generally provides that we will not engage Deloitte & Touche LLP to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved by the Audit Committee (“specific pre-approval”) or (ii) entered into pursuant to the pre-approval policies and procedures described in the Pre-Approval Policy (“general pre-approval”). Unless a type of service to be provided by Deloitte & Touche LLP has received general pre-approval under the Pre-Approval Policy, it requires specific pre-approval by the Audit Committee or by the Chair of the Audit Committee. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval. For both types of pre-approval, the Audit Committee will consider whether such services are consistent with the SEC’s rules on auditor independence. The Audit Committee will also consider whether the independent registered public accounting firm is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative. On a periodic basis, the Audit Committee reviews and generally pre-approves the services (and related fee levels or budgeted amounts) that may be provided by Deloitte & Touche LLP without first obtaining specific pre-approval from the Audit Committee. The Audit Committee may revise the list of general pre-approved services from time to time, based on subsequent determinations.

CORPORATE GOVERNANCE

General

Our Board of Directors has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics, and charters for our Nominating and Corporate Governance Committee, Audit Committee and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines, and our Code of Business Conduct and Ethics in the “Corporate Governance” section under the “Documents & Charters” in our investor relations section of our corporate website located at https://ir.imagobio.com, or by writing to our Corporate Secretary at our offices at 329 Oyster Point Blvd., 3rd Floor, South San Francisco, California 94080.

Board Composition

Our Board of Directors currently consists of seven members: Dennis Henner, Ph.D., Patrick Heron, Robert Baltera, M.S., Dina Chaya, Ph.D., Enoch Kariuki, Pharm.D., Hugh Y. Rienhoff, Jr., M.D. and Laurie Keating, J.D. However, Mr. Heron has not been nominated for re-election, and his Board service will end at the conclusion of the 2022 Annual Meeting. The Board has reduced the size of the Board to six directors, effective at the conclusion of the 2022 Annual Meeting. As set forth in our Amended and Restated Certificate of Incorporation, the Board of Directors is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our Amended and Restated Certificate of Incorporation provide 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. The division of our Board of Directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of our Company. Our directors may be removed only for cause by the affirmative vote of the holders of at least sixty-six and two-thirds percent (66-2/3%) of voting power of the outstanding shares of our capital stock entitled to vote in the election of directors.

Director Independence

Our Board of Directors has determined that all of our directors, other than Dr. Rienhoff, qualify as “independent” in accordance with the listing requirements of Nasdaq. The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, our Board of Directors has made a subjective determination as to each independent director that no relationships exist, which, 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.

Director Candidates

The Nominating and Corporate Governance Committee is primarily responsible for searching for qualified director candidates for election to the Board and filling vacancies on the Board. To facilitate the search process, the Nominating and Corporate Governance Committee may solicit current directors and executives of the Company for the names of potentially qualified candidates or ask directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders. Once potential candidates are

identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates’ independence from the Company and potential conflicts of interest and determines if candidates meet the qualifications desired by the Nominating and Corporate Governance Committee for candidates for election as a director.

In evaluating the suitability of individual candidates (both new candidates and current Board members), the Nominating and Corporate Governance Committee, in recommending candidates for election, and the Board, in approving (and, in the case of vacancies, appointing) such candidates, may take into account many factors, including: personal and professional integrity, ethics and values; experience in corporate management, such as serving as an officer or former officer of a publicly held company; experience as a board member of another publicly held company; professional and academic experience relevant to the Company’s industry; the strength of the candidate’s leadership skills; experience in finance and accounting and/or executive compensation practices; whether the candidate has the time required for preparation, participation and attendance at Board meetings and committee meetings, if applicable; diversity of background and perspective, including, but not limited to, with respect to gender, age and ethnicity; practical and mature business judgment, including, but not limited to, the ability to make independent analytical inquiries; and any other relevant qualifications, attributes or skills and any potential conflicts of interest with the candidate’s other personal and professional pursuits. The Board evaluates each individual in the context of the Board as a whole, with the objective of assembling a group that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas. In determining whether to recommend a director for re-election, the Nominating and Corporate Governance Committee may also consider the director’s past attendance at meetings and participation in and contributions to the activities of the Board.

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Corporate Secretary, Imago BioSciences, Inc., 329 Oyster Point Blvd., 3rd Floor, South San Francisco, California, 94080. For more information, see “Stockholders’ Proposals” on page 38. Assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

Communications from Stockholders

The Board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Our Corporate Secretary is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the directors as he/she considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that our Corporate Secretary and Chairperson of the Board consider to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications. Stockholders who wish to send communications on any topic to the Board should address such communications to the Board of Directors in writing: c/o Corporate Secretary, Imago BioSciences, Inc., 329 Oyster Point Blvd., 3rd Floor, South San Francisco, California, 94080.

Board Leadership Structure and Role in Risk Oversight

Our Amended and Restated Bylaws and Corporate Governance Guidelines provide our Board of Directors with flexibility to combine or separate the positions of Chairperson of the Board and Chief Executive Officer in

accordance with its determination that utilizing one or the other structure would be in the best interests of our Company. Dr. Henner currently serves as chair of the Board of Directors, and in such role presides over the executive sessions of the Board of Directors and acts as a liaison between management and the 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.

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. The Board of Directors has designated the Audit Committee to take the lead in overseeing risk management at the Board of Directors level. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. The Audit Committee schedules time for periodic review of risk management, in addition to its other duties. In this role, the Audit Committee receives reports from management, independent registered public accounting firm, outside legal counsel, and other advisors, and strives to generate serious and thoughtful attention to our risk management process and system, the nature of the material risks we face, and the adequacy of our policies and procedures designed to respond to and mitigate these risks. Our compensation committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

Board Diversity

Our Nominating and Corporate Governance Committee is responsible for reviewing with the Board of Directors, on an annual basis, the appropriate characteristics, skills and experience required for the Board of Directors as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current members), the Nominating and Corporate Governance Committee, in recommending candidates for election, and the Board of Directors, in approving (and, in the case of vacancies, appointing) such candidates, may take into account many factors, including but not limited to the following:

•

personal and professional integrity;

•

ethics and values;

•

experience in corporate management, such as serving as an officer or former officer of a publicly held company;

•

experience in the industries in which we compete;

•

experience as a board member of another publicly held company;

•

diversity, including diversity of expertise and experience in substantive matters pertaining to our business relative to other board members;

•

conflicts of interest; and

•

practical and mature business judgment.

Our Board of Directors evaluates each individual in the context of the Board of Directors as a whole, with the objective of assembling a group that can best maximize the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas.

⁽¹⁾	This table includes Mr. Heron, who is not nominated for re-election at the Annual Meeting. At the conclusion of the Annual Meeting, the size of our Board of Directors will be reduced to six directors.

Code of Business Conduct and Ethics

We have a written Code of Business Conduct and Ethics that applies to our directors, officers, employees, members of the scientific advisory board and consultants, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. We have posted a current copy of the Code of Business Conduct and Ethics on our investor relations website, https://ir.imagobio.com, in the “Corporate Governance” section under “Documents & Charters.” In addition, we intend to post on our website all disclosures that are required by law or the rules of Nasdaq concerning any amendments to, or waivers from, any provision of the Code of Business Conduct and Ethics.

Anti-Hedging Policy

Our Board of Directors has adopted an Insider Trading Compliance Policy, which applies to all of our directors, officers, employees, certain of our consultants and anyone else within the Company who has material, non-public information about the Company (collectively, the “insiders”). The policy prohibits the insiders from entering into hedging transactions involving our equity securities, including but not limited to, zero-cost collars and forward sale contracts that lock in much of the value of an insider’s stock holdings, often in exchange for all or part of the potential for upside appreciation in the stock. These transactions allow an insider to continue to own the securities, but without the full risks and rewards of ownership, which may cause the insider to no longer have the same objectives as the Company’s other stockholders.

Attendance by Members of the Board of Directors at Meetings

There were eight meetings of the Board of Directors during the fiscal year ended December 31, 2021. For such duration, each director attended at least 75% of the aggregate of (i) all meetings of the Board of Directors and (ii) all meetings of the committees on which the director served during the period in which he or she served as a director.

Under our Corporate Governance Guidelines, which is available on our investor relations website at https://ir.imagobio.com, a director is expected to spend the time and effort necessary to properly discharge his or

her responsibilities. Accordingly, a director is expected to regularly prepare for and attend meetings of the Board and all committees on which the director sits (including separate meetings of the independent directors), with the understanding that, on occasion, a director may be unable to attend a meeting. A director who is unable to attend a meeting of the Board or a committee of the Board is expected to notify the Chairperson of the Board or the Chairperson of the appropriate committee in advance of such meeting, and, whenever possible, participate in such meeting via teleconference in the case of an in-person meeting. We do not maintain a formal policy regarding director attendance at the Annual Meeting; however, it is expected that absent compelling circumstances directors will attend.

Compensation Committee Interlocks and Insider Participation

During 2021, Dennis Henner, Ph.D., Robert Baltera, M.S., and Dina Chaya, Ph.D. served on our Compensation Committee. During 2021, no such member of our Compensation Committee was an officer or employee of the Company, was formerly an officer of the Company or had related person transactions with the Company that required disclosure. During 2021, none of the Company’s executive officers served on the board of directors or the compensation committee of any other entity that had one or more of its executive officers serving on our Board of Directors or Compensation Committee.

Limitation on Liability and Indemnification Matters

Our Amended and Restated Certificate of Incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except for:

•

any breach of the director’s duty of loyalty to us or our stockholders;

•

any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

•

unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or

•

any transaction from which the director derived an improper personal benefit.

Each of our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provides that we are required to indemnify our directors and officers, in each case to the fullest extent permitted by Delaware law. Our Amended and Restated Bylaws also obligates us to advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding, and permits us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under Delaware law. We have entered and expect to continue to enter into agreements to indemnify our directors, executive officers and other employees as determined by our Board of Directors. With specified exceptions, these agreements provide for indemnification for related expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding. We believe that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also maintain directors’ and officers’ liability insurance.

The limitation of liability and indemnification provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws may discourage stockholders from bringing a lawsuit against our directors and officers for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and our stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage.

Corporate Social Responsibility

Corporate social responsibility is central to our business practices, the continuous improvement of our operations, and our relationships with our employees and the communities in which we do business. We have been focused on delivering strong financial results, and we remain committed to doing so in a way that respects our key stakeholders, including our employees and the environments and communities in which we operate. For this reason, we consider material environmental, social and governance (“ESG”) factors when making investment and operational decisions. Doing so will help our business have a positive impact on the planet, the people whose lives we touch and our bottom line. While we are early in our ESG journey, we believe that our business is closely aligned to the underlying messages of ESG and expect to continue to explore, and report on, our efforts to pursue ESG opportunities as we navigate our ESG risks.

Our Board has established three standing committees, the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee, each of which operates under a written charter that has been approved by our Board.

Radford consulted with the members of our management regarding various aspects of executive and director compensation, including with respect to our long-term incentive program.

The members of our Compensation Committee are Dennis Henner, Ph.D., Robert Baltera, M.S. and Dina Chaya, Ph.D., and Dr. Henner serves as the Chairperson of the Compensation Committee. Each member of the Compensation Committee qualifies as an independent director under Nasdaq’s heightened independence standards for members of a compensation committee and as a “non-employee director” as defined in Rule 16b-3 of the Exchange Act.

In connection with our IPO, we adopted a non-employee director compensation program, which was amended in November 2021 (the “Director Compensation Program”). Pursuant to the Director Compensation Program, our non-employee directors will receive cash compensation as follows:

•

Each non-employee director will receive an annual cash retainer in the amount of $40,000 per year.

Under the Director Compensation Program, each non-employee director will automatically be granted an option to purchase 23,809 shares of our common stock upon the director’s initial appointment or election to our Board of Directors, referred to as the Initial Grant. Each non-employee director who has served for at least six months as of the date of each annual stockholders’ meeting will automatically be granted an option to purchase 11,904 shares of our common stock on the date of each annual stockholders’ meeting, referred to as the Annual Grant. The Initial Grant will vest and become exercisable as to 1/36th of the underlying shares on a monthly basis over three years, subject to continued service through each applicable vesting date. The Annual Grant will vest and become exercisable on the first anniversary of the date of grant, provided, that if our annual stockholders’ meeting immediately following the date of grant takes place prior to the first anniversary of the date of grant, the Annual Grant will vest and become exercisable immediately prior to our annual stockholders’ meeting following the date of grant, subject to continued service through each applicable vesting date.

In the event of a change in control (as defined in the Director Compensation Program), each option granted pursuant to the Initial Grant and Annual Grant, along with any other stock options or equity-based awards held by any non-employee director, will vest and become exercisable immediately prior to such change in control.

Executive Compensation

This section discusses the material components of the executive compensation program for our executive officers who are named in the 2021 Summary Compensation Table below (our “named executive officers” or “NEOs”).

Narrative to Summary Compensation Table

2021 Salaries

Our NEOs each receive a base salary to compensate them for services rendered to our company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities.

In connection with our IPO, our Board of Directors increased the annual base salaries of Dr. Rienhoff, Ms. Eichorn and Dr. Plunkett to $517,500, $350,800 and $411,900, respectively. In connection with Dr. Hong’s commencement of employment with us, her annual base salary was established at $400,000 and increased in connection with our IPO to $443,900.

Our Board of Directors and Compensation Committee may adjust base salaries from time to time in their discretion.

2021 Bonuses

We maintain an annual performance-based cash bonus program in which each of our NEOs participated in 2021. Each NEO’s target bonus is expressed as a percentage of the NEO’s annual base salary which can be achieved by meeting company and individual goals at target level. The 2021 annual bonus for Dr. Rienhoff was targeted at 50% of his annual base salary, and the 2021 annual bonuses for Ms. Eichorn, Dr. Hong and Dr. Plunket were targeted at 40% of their annual base salaries, Our Board of Directors has historically reviewed these target percentages to ensure they provide appropriate incentives to achieve the performance objectives established for the year. Our Board of Directors sets these rates based on each NEO’s experience in the NEO’s role with us and the level of responsibility held by the NEO, which we believe directly correlates to the NEO’s ability to influence corporate results.

For determining the 2021 performance bonus amounts, our Board of Directors evaluated Dr. Rienhoff 100% based on the achievement of corporate performance goals and the other NEOs 75% based on the achievement of corporate performance goals and 25% based on the achievement of individual performance goals. For 2021, our Board of Directors set certain corporate performance goals after receiving input from our Chief Executive Officer, in two broad strategic areas: corporate and research and development. Each area included specific performance objectives. Following its review and determinations of corporate and individual performance for 2021, our Board of Directors determined an achievement level of 85.25% for corporate goals and, for each NEO other than Dr. Rienhoff, whose bonus is determined based solely on corporate performance, 100% for individual performance goals. The actual amount of the 2021 annual bonus paid to each NEO for 2021 performance is set forth above in the Summary Compensation Table in the column titled “Non-Equity Incentive Plan Compensation.”

Equity-Based Compensation

In February 2021, we granted each of Dr. Rienhoff, Ms. Eichorn and Dr. Plunkett an option to purchase 609,441, 23,809 and 314,285 shares of our common stock, respectively. Each option has an exercise price per share of $4.20 and vests and becomes exercisable as to 25% of the shares on February 5, 2022 and as to 1/48th of the shares on each monthly anniversary over the three-year period thereafter, subject to the applicable NEO’s continued service through the applicable vesting date.

In connection with Dr. Hong’s commencement of employment with us, we granted her an option to purchase 259,523 shares of our common stock. The option has an exercise price per share of $7.06 and vests and becomes exercisable as to 25% of the shares on May 24, 2022 and as to 1/48th of the shares on each monthly anniversary over the three-year period thereafter, subject to Dr. Hong’s continued service through the applicable vesting date.

In November 2021, we granted each of Dr. Rienhoff, Ms. Eichorn and Dr. Hong an option to purchase 306,000, 103,000 and 62,000 shares of our common stock, respectively. Each option has an exercise price per share of $22.76 and vests and becomes exercisable as to 25% of the shares on November 17, 2022 and as to 1/48th of the shares on each monthly anniversary over the three-year period thereafter, subject to the applicable NEO’s continued service through the applicable vesting date.

Other Elements of Compensation—Retirement Savings and Health and Welfare Benefits

The Company currently maintains a 401(k) retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. Our named executive officers are eligible to participate in the 401(k) plan on the same terms as other full-time employees.

All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, including medical, dental and vision benefits; medical and dependent care flexible spending accounts; short-term and long-term disability insurance; and life and AD&D insurance. Employees who choose

not to enroll in health insurance through us, including Ms. Eichorn, are eligible to be paid a monthly stipend of $425, which, for 2021, was $5,100.

Perquisites and Other Personal Benefits

We reimburse our employees, including our named executive officers, a fixed amount of $120 per month for internet and cellular phone usage. We do not provide our named executive officers with any other perquisites. Our compensation committee may from time to time approve additional perquisites in the future when it determines that such perquisites are necessary or advisable to fairly compensate or incentivize our employees.

Executive Compensation Arrangements

Employment Agreements

Hugh Y. Rienhoff, Jr., M.D. In July 2014, we entered into an employment agreement, with Dr. Rienhoff, which sets forth an initial base salary, stock grant and eligibility to participate in our benefit plans.

In the event such qualifying termination occurs within three months prior to or nine months after a change in control, then he shall receive the accelerated vesting of 100% of his outstanding equity awards. Dr. Rienhoff’s receipt of the separation payments and benefits are expressly conditioned upon Dr. Rienhoff’s execution of a general release of claims against us and our affiliates.

Change in Control and Severance Agreements.

In connection with our IPO, we entered into a Change in Control and Severance Agreement with each of our NEOs. Under each Change in Control and Severance Agreement, if we terminate the employment of the NEO without cause or the NEO resigns for good reason, the NEO will be entitled to (i) a payment equal to nine months, or in the case of our Chief Executive Officer, twelve months, of the NEO’s annual base salary and (ii) nine months, or in the case of our Chief Executive Officer, twelve months of company payment of COBRA premiums.

In connection with Dr. Plunkett’s termination of employment, on September 28, 2021 we entered into a Separation and Release Agreement with Dr. Plunkett (the “Separation Agreement”). The Separation Agreement provided for Dr. Plunkett to receive severance benefits of nine months of his base salary and reimbursement of his premiums to continue healthcare coverage under COBRA for up to ten months. As per the terms of Dr. Plunkett’s employment agreement, six months accelerated vesting of certain of his Company stock option grants (his stock options granted by the Company in 2021) resulted in an additional 91,664 shares vested of Company common stock. The Separation Agreement included a release of claims and certain restrictive covenants.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information with respect to holdings of our Common Stock by (i) stockholders who beneficially owned more than 5% of the outstanding shares of our Common Stock, and (ii) each of our directors (which includes the nominee for election as a Class I Director at the Annual Meeting), each of our named executive officers and all directors and executive officers as a group as of March 31, 2022, unless otherwise indicated.

The number of shares beneficially owned by each stockholder as described in this proxy statement is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. Applicable percentage ownership is based on 33,733,683 shares of Common Stock outstanding as of March 31, 2022. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of Common Stock subject to options, or other rights, held by such person that are currently exercisable or will become exercisable within 60 days of March 31, 2022, are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Policies and Procedures for Related Person Transactions

Our Board of Directors has adopted a written Related Person Transaction Policy and Procedures, setting forth the policies and procedures for the review and approval or ratification of related person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships in which we were, are or will be a participant, where the amount involved exceeds $120,000 and a related person had, has or will have a direct or indirect material interest, including without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness and guarantees of indebtedness; provided that, if we qualify as a “smaller reporting company” pursuant to the rules of the SEC, a “Related Person Transaction” is a transaction, arrangement or relationship in which we were, are or will be a participant, where the amount involved exceeds the lesser of (1) $120,000 or (2) one percent of the average of our total assets at fiscal year-end for the last two completed fiscal years, and in which any related person had, has or will have a direct or indirect material interest.

Under the policy, our finance department is primarily responsible for developing and implementing processes and procedures to obtain information regarding related persons with respect to potential related person transactions and then determining, based on the facts and circumstances, whether such potential related person transactions do, in fact, constitute related person transactions requiring compliance with the policy. In addition, any potential related person transaction that is proposed to be entered into by the Company must be reported to the Chief Financial Officer by both the related person and the person at the Company responsible for such potential related person transaction. If our finance department determines that a transaction or relationship is a related person transaction requiring compliance with the policy, our Chief Financial Officer (or his or her designee) is required to present to the Audit Committee all relevant facts and circumstances relating to the related person transaction. Our Audit Committee must review the relevant facts and circumstances of each related person transaction, including whether the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party, whether the transaction arose in the ordinary course of business, and the extent of the related person’s interest in the transaction, take into account the conflicts of interest and corporate opportunity provisions of our Code of Business Conduct and Ethics, and either approve or disapprove the related person transaction. If advance Audit Committee approval of a related person transaction requiring the Audit Committee’s approval is not feasible, then the transaction may be preliminarily entered into by management upon prior approval of the transaction by the chair of the Audit Committee subject to ratification of the transaction by the Audit Committee at the Audit Committee’s next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction. If a transaction was not initially recognized as a related person, upon such recognition the transaction will be presented to the Audit Committee for ratification at the Audit Committee’s next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction.

Our management will update the Audit Committee as to any material changes to any approved or ratified related person transaction and will provide a status report at least quarterly of all then current related person transactions. No director may participate in approval of a related person transaction for which he or she is a related person.

The following are certain transactions, arrangements and relationships with our directors, executive officers and stockholders owning 5% or more of our outstanding Common Stock, or any member of the immediate family of any of the foregoing persons, since January 1, 2021, other than equity and other compensation, termination, change in control and other arrangements, which are described under “Executive and Director Compensation.”

Convertible Note Financing

In November 2018, we entered into a note purchase agreement pursuant to which we issued, in two tranches, subordinated convertible promissory notes, or the Bridge Notes, in an aggregate principal amount of

$2.5 million. The Bridge Notes provided for an annual interest rate of 8.0% and a maturity date of May 19, 2019. Under the terms of the Bridge Notes, under certain circumstances, the unpaid principal of the Bridge Notes, including any accrued but unpaid interest thereon, would convert into preferred stock upon the closing of a future preferred stock financing that met specified criteria. In March 2019, as part of the issuance of Series B convertible preferred stock, the outstanding principal under the Bridge Notes, plus approximately $64,157 of accrued interest, converted into 74,817 shares of Series B Preferred Stock at a rate of $5.712 per share in full payment for the Bridge Notes and accrued interest. The table below sets forth the principal amount of the Bridge Notes and the number of shares of Series B convertible preferred stock issued to our directors, executive officers or owners of more than 5% of our capital stock, or an affiliate or immediate family member thereof upon conversion of outstanding principal and unpaid, accrued interest under the Bridge Notes:

Indemnification Agreements and Directors’ and Officers’ Liability Insurance

Investor Rights Agreement

We entered into an amended and restated investor rights agreement with the purchasers of our outstanding convertible preferred stock, including entities with which certain of our directors are affiliated.

Under our amended and restated investors’ rights agreement, following the consummation of our IPO, the holders of approximately 21.4 million shares of Common Stock converted from shares of our preferred stock (the “Pre-IPO Shares”), or their transferees, have the right to require us to register their shares under the Securities Act so that those shares may be publicly resold, and the holders of such shares of Common Stock, or their transferees, have the right to include their shares in any registration statement we file, in each case as described below.

Demand Registration Rights

Following the consummation of the IPO and the concurrent private placement discussed above, holders of the Pre-IPO Shares, or their transferees, are entitled to certain demand registration rights. Beginning six months following the effectiveness of the registration statement of our IPO, the holders of at least 65% of these shares can request that we register all or a portion of their shares if the aggregate price to the public of the shares offered is at least $15 million. Additionally, we are not required to effect a demand registration during the period beginning 90 days prior to the filing and ending 180 days following the effectiveness of a company-initiated registration statement relating to a public offering of our securities.

Piggyback Registration Rights

Following the consummation of the IPO and the concurrent private placement discussed above, in the event that we determine to register any of our securities under the Securities Act (subject to certain exceptions), either for our own account or for the account of other security holders, the holders of the Pre-IPO Shares, or their transferees, are entitled to certain “piggyback” registration rights allowing the holders to include their shares in such registration, subject to certain marketing and other limitations. As a result, whenever we propose to file a registration statement under the Securities Act, other than with respect to a registration related to employee benefit plans, the offer and sale of debt securities, or corporate reorganizations or certain other transactions, the holders of these shares are entitled to notice of the registration and have the right, subject to limitations that the underwriters may impose on the number of shares included in the registration, to include their shares in the registration. In an underwritten offering, the managing underwriter, if any, has the right, subject to specified conditions, to limit the number of shares such holders may include.

Form S-3 Registration Rights

Following the consummation of this offering and the concurrent private placement, the holders of the Pre-IPO Shares, or their transferees, are entitled to certain Form S-3 registration rights. The holders of at least 65% of these shares can make a written request that we register their shares on Form S-3 if we are eligible to file a registration statement on Form S-3 and if the aggregate price to the public of the shares offered is at least $2.5 million, net of underwriting discounts and commissions. These stockholders may make an unlimited number of requests for registration on Form S-3, but in no event shall we be required to file more than two registrations on Form S-3 in any given 12 month period.

Expenses of Registration

We will pay the registration expenses of the holders of the shares registered pursuant to the demand, piggyback and Form S-3 registration rights described above, including the expenses of one counsel for the selling holders.

Expiration of Registration Rights

The demand, piggyback and Form S-3 registration rights described above will expire, with respect to any particular stockholder, upon the earlier of five years after the consummation of the IPO or when that stockholder can sell all of its shares under Rule 144 of the Securities Act during any three-month period, or upon an acquisition of the Company by a company subject to and in compliance with the reporting provisions of the Exchange Act.

Rights of First Refusal

The amended and restated investor rights agreement also provides for a right of first refusal in favor of certain holders of convertible preferred stock with regard to certain issuances of our capital stock. The rights of first refusal were terminated upon the consummation of the IPO.

Voting Agreement

We entered into an amended and restated voting agreement with certain holders of our Common Stock and convertible preferred stock. The agreement was terminated upon the consummation of the IPO.

Right of First Refusal and Co-Sale Agreement

We entered into an amended and restated right of first refusal and co-sale agreement with certain holders of our Common Stock and convertible preferred stock.

The agreement was terminated upon the consummation of the IPO.
