PROXY STATEMENT

FOR THE 2021 ANNUAL MEETING OF STOCKHOLDERS

To Be Held On June 16, 2021

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

Why did I receive a notice regarding the availability of proxy materials on the internet?

Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the “Notice”) because the Board of Directors (sometimes referred to as the “Board”) of Poseida Therapeutics, Inc. (sometimes referred to as the “Company” or “Poseida”) is soliciting your proxy to vote at the 2021 Annual Meeting of Stockholders (“Annual Meeting”), including at any adjournments or postponements of the Annual Meeting. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice. We intend to mail the Notice on May 5, 2021 to all stockholders of record entitled to vote at the Annual Meeting.

Will I receive any other proxy materials by mail?

We may send you a proxy card, along with a second Notice, on or after May 15, 2021.

Why are we holding a virtual Annual Meeting?

This year we have implemented a virtual format for our Annual Meeting, which will be conducted via live audio webcast and online stockholder tools. Given the evolving situation relating to the COVID-19 pandemic, we believe a virtual format helps to facilitate stockholder attendance and participation by enabling stockholders to participate fully, and equally, from any location around the world without person-to-person contact, at no cost (other than any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies). A virtual Annual Meeting makes it possible for more stockholders (regardless of size, resources or physical location) to have direct access to information more quickly, while saving the Company and our stockholders time and money. We also believe that the online tools we have selected will increase stockholder communication. For example, the virtual format allows stockholders to communicate with us in advance of the Annual Meeting so they can submit questions of our Board or management. During the Annual Meeting, we may answer questions submitted in advance, to the extent relevant to the business of the Annual Meeting, as time permits.

What do I need to do to attend the Annual Meeting?

In order to attend the Annual Meeting, you must register at www.proxydocs.com/PSTX. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting and to vote during the Annual Meeting and to submit questions of our Board or management in advance of the Annual Meeting.

As part of the registration process, you must enter the control number located on your proxy card, voting instruction form, or Notice. If you are a beneficial owner of shares registered in the name of a broker, bank or other nominee, you will also need to provide the registered name on your account and the name of your broker, bank or other nominee as part of the registration process.

On the day of the Annual Meeting, stockholders may begin to log in to the virtual-only Annual Meeting 15 minutes prior to the Annual Meeting. The Annual Meeting will begin promptly at 1:00 p.m. Pacific Time on Wednesday, June 16, 2021. We encourage you to access the meeting prior to the start time which should allow ample time to check your audio settings.

We will have technicians ready to assist you with any technical difficulties you may have accessing the Annual Meeting. If you encounter any difficulties accessing the virtual-only Annual Meeting platform, including any difficulties voting, you may call the technical support number that will be posted in your instructional email.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on April 20, 2021, will be entitled to vote at the Annual Meeting. On the record date, there were 62,133,411 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on April 20, 2021, your shares were registered directly in your name with Poseida’s transfer agent, Computershare Trust Company N.A., then you are a stockholder of record. As a stockholder of record, you may vote live online at the Annual Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to fill out and return the proxy card that may be mailed to you, to vote by proxy over the telephone, or vote by proxy through internet as instructed below to ensure your vote is counted.

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

If on April 20, 2021, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares live at the meeting unless you request and obtain a valid proxy from your broker or other agent.

What am I voting on?

There are two matters scheduled for a vote:

•

Proposal 1: Election of the Board’s nominee for director named herein to hold office until the 2024 Annual Meeting of Stockholders; and

•

Proposal 2: Ratification of the selection by the Audit Committee of the Board of Directors of PricewaterhouseCoopers LLP as the independent registered public accounting firm of the Company for its fiscal year ending December 31, 2021.

What if another matter is properly brought before the meeting?

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 those matters in accordance with their best judgment.

How do I vote?

You may either vote “For” the nominee to the Board of Directors or you may “Withhold” your vote for the nominee. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are fairly simple:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote live online at the Annual Meeting, vote by proxy over the telephone, vote by proxy through the internet or vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may

still attend the meeting and vote live online even if you have already voted by proxy.

•

To vote live at the Annual Meeting, attend the Annual Meeting by visiting www.proxydocs.com/PSTX where stockholders may vote during the meeting (have your Notice or proxy card in hand when you visit the website).

•

To vote using the proxy card, simply complete, sign and date the proxy card that may be delivered to you 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.

•

To vote over the telephone, dial toll-free (866) 859-1992 and follow the recorded instructions. You will be asked to provide the company number and control number from the Notice. Your telephone vote must be received prior to the start of the meeting to be counted.

•

To vote through the internet, go to www.proxypush.com/PSTX and follow the on-screen instructions to complete an electronic proxy card or scan the QR code on your proxy notice with your smartphone. You will be asked to provide the control number from the Notice or proxy card. Your internet vote must be received prior to the start of the meeting to be counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a Notice containing voting instructions from that organization rather than from the Company. Simply follow the voting instructions in the Notice to ensure that your vote is counted. To vote live online at the Annual Meeting, you may be required to obtain a valid proxy from your broker, bank or other agent. You must also register by visiting www.proxydocs.com/PSTX. Follow the instructions from your broker or bank included with these proxy materials, and the instructions you receive via email after registration, or contact your broker or bank to request a proxy form.

Internet proxy voting is being provided 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 close of business on April 20, 2021.

If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens?

If you are a shareholder of record and do not vote by completing your proxy card, by telephone, through the internet or online at the Annual Meeting, your shares will not be voted.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of the nominee for director, and “For” the ratification of PricewaterhouseCoopers LLP as the independent registered public accounting firm of the Company. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

If I am a beneficial owner of shares held in street name and I do not provide my broker or bank with voting instructions, what happens?

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. In this regard, under the rules of the New York Stock Exchange (“NYSE”), brokers, banks and other securities intermediaries that are subject to NYSE rules may use their discretion to vote your “uninstructed” shares with respect to matters considered to be “routine” under NYSE rules, but not with respect to “non-routine” matters. In this regard, Proposal 1 is considered to be “non-routine” under NYSE rules meaning that your broker may not vote your shares on those proposals in the absence of your voting instructions. However, Proposal 2 is considered to be a “routine” matter under NYSE rules meaning that if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposal 2.

If you a beneficial owner of shares held in street name, and you do not plan to attend the Annual Meeting, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding 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 may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notices to ensure that all of your shares are voted.

Can I change my vote after submitting my proxy?

Stockholder of Record: Shares Registered in Your Name

Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

•

You may submit another properly completed proxy card with a later date.

•

You may grant a subsequent proxy by telephone or through the internet.

•

You may send a timely written notice that you are revoking your proxy to the Company’s Corporate Secretary at 9390 Towne Centre Drive, Suite 200, San Diego, California 92121.

•

You may attend and vote online at the Annual Meeting. Attendance at the Annual Meeting will not, by itself, revoke a proxy.

Your most current proxy card or telephone or internet proxy is the one that is counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

When are stockholder proposals and director nominations due for next year’s annual meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by January 5, 2022, to Attention: Corporate Secretary, 9390 Towne Centre Drive, Suite 200, San Diego, California 92121. If you wish to submit a proposal (including a director nomination) at the meeting that is not to be included in next year’s proxy materials, you must do so between February 16, 2022 and March 18, 2022. You are also advised to review the Company’s Amended and Restated Bylaws (“Bylaws”), which contain additional requirements relating to advance notice of stockholder proposals and director nominations.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for Proposal 1 to elect directors, votes “For,” “Withhold” and broker non-votes; and for Proposal 2 to ratify the Audit Committee’s selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm, votes “For” and “Against,” abstentions and, if applicable, broker non-votes. Abstentions will have no effect on Proposal 1. Abstentions will be counted towards the vote total for Proposal 2 and will have the same effect as “Against” votes. Broker non-votes will be counted towards the presence of a quorum but will not be counted towards the vote total for any proposal.

What are “broker non-votes”?

As discussed above, when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed by the NYSE to be “non-routine,” the broker or nominee cannot vote the shares. These un-voted shares are counted as “broker non-votes.” Proposal 1 is considered to be “non-routine” under NYSE rules and we therefore expect broker non-votes to exist in connection with this proposal.

As a reminder, if you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.

How many votes are needed to approve each proposal?

The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

Proposal Number	Proposal Description	Vote Required for Approval	Effect of Abstentions	Effect of Broker Non-Votes

1	Election of Directors	Nominee receiving the most “For” votes from the holders of shares present at the Annual Meeting or represented by proxy and entitled to vote on the matter; withheld votes will have no effect.	Not applicable	No effect

2	Ratification of the selection of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for fiscal year 2021	“For” votes from the holders of a majority of shares present at the Annual Meeting or represented by proxy and entitled to vote on the matter	Against	Not applicable

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present at the meeting or represented by proxy. On April 20, 2021, the record date, there were 62,133,411 shares outstanding and entitled to vote. Thus, the holders of 31,066,706 shares must be present at the Annual Meeting or represented by proxy at the meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote live online at the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares present at the meeting or represented by proxy may adjourn the meeting to another date.

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

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8- K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

PROPOSAL 1

ELECTION OF DIRECTORS

Our Board of Directors is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors, and each class has a three-year term. Vacancies on the Board of Directors may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board of Directors to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.

The following table sets forth certain information regarding our directors, including their ages as of the Annual Meeting:

Class	Name	Age	Position Held With the Company
I	Catherine J. Mackey, Ph.D.(1)	65	Director
I	Sean Murphy(1)	68	Director
I	John Schmid	58	Director
II	Luke Corning	39	Director
II	Mark J. Gergen, J.D.	59	President, Chief Business Officer and Director
II	Marcea B. Lloyd, J.D.	72	Director
III	David Hirsch, M.D., Ph.D.	50	Director
III	Eric Ostertag, M.D., Ph.D.	48	Chief Executive Officer and Director

(1) Dr. Mackey and Mr. Murphy will not stand for reelection at the Annual Meeting.

Our Board of Directors currently consists of eight members. There are three directors in Class I, whose term of office expires at the Annual Meeting: Dr. Mackey, Mr. Murphy and Mr. Schmid. Dr. Mackey and Mr. Murphy have notified us that they will not stand for reelection at the Annual Meeting. As such, each of Dr. Mackey’s and Mr. Murphy’s tenure on the Board of Directors will come to an end as of the conclusion of the Annual Meeting. As Dr. Mackey and Mr. Murphy will not stand for reelection at the Annual Meeting, there are fewer nominees than the authorized number of directors. We expect that, following the conclusion of the Annual Meeting, the authorized size of the Board of Directors will be reduced to six members. Proxies cannot be voted for a greater number of persons than the number of nominees named in this proxy statement.

Mr. Schmid, the nominee listed below, is currently a director of the Company who was previously elected by the stockholders. If elected at the Annual Meeting, Mr. Schmid would serve until the 2024 annual meeting and until his successor has been duly elected and qualified, or, if sooner, until his death, resignation or removal. It is the Company’s policy to encourage directors and nominees for director to attend the Annual Meeting.

Directors are elected by a plurality of the votes of the holders of shares present or represented by proxy and entitled to vote on the election of directors. Accordingly, the nominee receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nominee named below. If a nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by Poseida. Each person nominated for election has agreed to serve if elected. The Company’s management has no reason to believe that any nominee will be unable to serve.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE NAMED NOMINEE.

INFORMATION REGARDING DIRECTOR NOMINEES AND CURRENT DIRECTORS

The following is a brief biography of the director nominee and each director whose term will continue after the Annual Meeting.

Class I Director Nominee for Election for a Three-year Term Expiring at the 2024 Annual Meeting

John P. Schmid. Mr. Schmid has served as a member of our Board of Directors since July 2018. Mr. Schmid serves as Chairperson of the Audit Committee and as a member of the Nominating and Corporate Governance Committee of our Board of Directors. From September 2013 to June 2015, Mr. Schmid served as Chief Financial Officer of Auspex Pharmaceuticals, Inc., a publicly held biopharmaceutical company that focused on developing and commercializing medicines for the treatment of orphan diseases until its sale to Teva Pharmaceutical Industries Ltd. From June 2004 to September 2013, Mr. Schmid co-founded Trius Therapeutics, a publicly held biopharmaceutical company focused on the discovery, development, and commercialization of antibiotics for serious infections, where he served as the Chief Financial Officer until its merger with Cubist Pharmaceuticals, Inc.

From 1995 to 1998, Mr. Schmid served as the Chief Financial Officer of Endonetics Inc., a medical device company. Mr. Schmid currently serves as a member of the boards of directors of AnaptysBio, Inc., Xeris Pharmaceuticals, and Design Therapeutics and formerly Neos Therapeutics (June 2015 to March 2021) all publicly held companies in the pharmaceutical industry.

Mr. Schmid received his M.B.A. from the University of San Diego and his B.A. in Economics from Wesleyan University. We believe that Mr. Schmid’s extensive finance experience and leadership positions at multiple biopharmaceutical companies qualifies him to serve on our Board of Directors.

Our Nominating and Corporate Governance Committee and Board of Directors believes Mr. Schmid’s extensive finance experience and leadership positions at multiple biopharmaceutical companies provide him with the qualifications and skills to serve on our Board of Directors.

Class II Directors Continuing in Office Until the 2022 Annual Meeting

Luke Corning. Mr. Corning has served as a member of our Board of Directors since December 2020. Mr. Corning is Portfolio Manager and Head of Credit at Pentwater Capital Management. Mr. Corning has managed the credit team at Pentwater since August 2015 and prior to that he was a Portfolio Manager from November 2014 to August 2015. Prior to Pentwater, he was a Portfolio Manager at TLP Trading from September 2006 to October 2014. Mr. Corning began his career as an analyst at Goldman, Sachs & Co. in 2004. Mr. Corning received his B.S. in Finance from Miami University of Ohio, and is an alumnus of the Program for Leadership Development at Harvard Business School. Mr. Corning serves on a number of boards of directors, including Malin Corporation, Plc, a publicly held life science investment company. We believe that Mr. Corning’s broad perspective and experience as an investor and analyst including his experience in life science investing qualifies him to serve on our Board of Directors.

Mark J. Gergen, J.D. Mr. Gergen has served as our President since July 2020 and our Chief Business Officer since February 2018. From February 2018 to July 2020 he served as our Chief Financial Officer.

From February 2013 to August 2016, Mr. Gergen served as Executive Vice President and Chief Operating Officer of Mirati Therapeutics, Inc., a publicly held clinical-stage biopharmaceutical company focused on developing a pipeline of targeted oncology products. From May 2005 to November 2012, Mr. Gergen served in senior management positions, including most recently as Senior Vice President, Corporate Development, at Amylin Pharmaceuticals, Inc., publicly held biopharmaceutical company that was focused on the development and commercialization of medicines to treat chronic diseases. From July 2003 to March 2005, Mr. Gergen served as Executive Vice President of CardioNet Inc., a cardiovascular diagnostic company.

Mr. Gergen received his J.D. from the University of Minnesota Law School and his B.A. in Business Administration from Minot State University. We believe Mr. Gergen’s extensive operational and transactional experience in the life science industry qualifies him to serve on our Board of Directors.

Ms. Lloyd serves as Chairperson of the Nominating and Corporate Governance Committee and as a member of the Compensation Committee of our Board of Directors.

Ms. Lloyd received her B.S. and B.A. in sociology and psychology from Knox College and her J.D. from Northwestern University. We believe that Ms. Lloyd’s extensive legal, administrative and operational experience in the life sciences industry qualifies her to serve on our Board of Directors.

Class III Directors Continuing in Office Until the 2023 Annual Meeting

David Hirsch, M.D., Ph.D. Dr. Hirsch has served as a member of our Board of Directors since March 2018. Dr. Hirsch serves as a member of the Audit Committee of our Board of Directors. Since 2007, Dr. Hirsch has served as a Managing Director of Longitude Capital Management Co., LLC, a venture capital firm Dr. Hirsch co-founded, where he focuses on investments in biotechnology. Dr. Hirsch currently serves on the boards of directors of Tricida, Inc. and Molecular Templates, Inc., which are publicly held companies and Amunix Pharmaceuticals, Inc. and Rapid Micro Biosystems, Inc., which are private companies.

Dr. Hirsch holds a Ph.D. in Biology from the Massachusetts Institute of Technology, an M.D. from Harvard Medical School and a B.A. in Biology from Johns Hopkins University. We believe that Dr. Hirsch’s perspective and experience as an investor and board member in the life sciences industry, as well as his strong medical and scientific background, qualifies him to serve on our Board of Directors.

Eric Ostertag, M.D., Ph.D. Dr. Ostertag directed Poseida’s spin out from Transposagen in February 2015 and has served as our Chief Executive Officer and as a member of our Board of Directors since May 2015.

We believe that Dr. Ostertag’s extensive experience and leadership in the life science industry qualifies him to serve on our Board of Directors.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Independence of The Board of Directors

As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of a listed company’s Board of Directors must qualify as “independent,” as affirmatively determined by its Board of Directors. The Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent registered public accounting firm, the Board has affirmatively determined that all of our current directors other than Dr. Ostertag and Mr. Gergen were independent directors within the meaning of the applicable Nasdaq listing standards. In making this determination, the Board found that none of these directors had a material or other disqualifying relationship with the Company.

Board Leadership Structure

The Board of Directors is currently chaired by the Chief Executive Officer of the Company, Dr. Ostertag. The Board has also appointed Dr. Mackey as lead independent director.We expect Mr. Schmid will serve as lead independent director following the Annual Meeting.

The Company believes that combining the positions of Chief Executive Officer and Chairperson helps to ensure that the Board and management act with a common purpose. In the Company’s view, separating the positions of Chief Executive Officer and Chairperson has the potential to give rise to divided leadership, which could interfere with good decision-making or weaken the Company’s ability to develop and implement strategy. Instead, the Company believes that combining the positions of Chief Executive Officer and Chairperson provides a single, clear chain of command to execute the Company’s strategic initiatives and business plans. In addition, the Company believes that a combined Chief Executive Officer/ Chairperson is better positioned to act as a bridge between management and the Board, facilitating the regular flow of information. The Company also believes that it is advantageous to have a Chairperson with an extensive history with and knowledge of the Company (as is the case with the Company’s Chief Executive Officer) as compared to a relatively less informed independent Chairperson.

The Board appointed Dr. Mackey, and following the Annual Meeting, expects to appoint Mr. Schmid, as the lead independent director to help reinforce the independence of the Board as a whole. The position of lead independent director has been structured to serve as an effective balance to a combined Chief Executive Officer/Chairperson: the lead independent director is empowered to, among other duties and responsibilities, approve agendas and meeting schedules for regular Board meetings, preside over Board meetings in the absence of the Chairperson, preside over and establish the agendas for meetings of the independent directors, act as liaison between the Chairperson and the independent directors, approve information sent to the Board, preside over any portions of Board meetings at which the evaluation or compensation of the Chief Executive Officer is presented or discussed and, as appropriate upon request, act as a liaison to stockholders. In addition, it is the responsibility of the lead independent director to coordinate between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues. As a result, the Company believes that the lead independent director can help ensure the effective independent functioning of the Board in its oversight responsibilities. In addition, the Company believes that the lead independent director is better positioned to build a consensus among directors and to serve as a conduit between the other independent directors and the Chairperson, for example, by facilitating the inclusion on meeting agendas of matters of concern to the independent directors. In light of the Chief Executive Officer’s extensive history with and knowledge of the Company, and because the Board’s lead independent director is empowered to play a significant role in the Board’s leadership and in reinforcing the independence of the Board, the Company believes that it is advantageous for the Company to combine the positions of Chief Executive Officer and Chairperson.

Role of the Board in Risk Oversight

One of the Board’s key functions is informed oversight of the Company’s risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole,

as well as through various standing Board committees that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company. Our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function. Audit Committee responsibilities also include oversight of cybersecurity risk management, and, to that end, the committee typically meets twice annually with both IT and business personnel responsible for cybersecurity risk management and receives periodic reports from the head of cybersecurity risk management, as well as incidental reports as matters arise. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. Typically, the entire Board meets with the head of the Company’s risk management group at least annually, and the applicable Board committees meet at least annually with the employees responsible for risk management in the committees’ respective areas of oversight. Both the Board as a whole and the various standing committees receive periodic reports from the head of risk management, as well as incidental reports as matters may arise. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board as quickly as possible. The Board has delegated to the Board’s lead independent director the responsibility of coordinating between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues.

Meetings of The Board of Directors

The Board of Directors met seven times during the last fiscal year. Each Board member attended 75% or more of the aggregate number of meetings of the Board and of the committees on which he or she served, held during the portion of the last fiscal year for which he or she was a director or committee member.

Information Regarding Committees of the Board of Directors

The Board maintains an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The following table provides membership and meeting information for 2020 for each of the foregoing Board committees:

The Board of Directors has determined that each member of each committee meets the applicable Nasdaq rules and regulations regarding “independence” and each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

Below is a description of each committee of the Board of Directors.

Audit Committee

The Audit Committee of the Board of Directors was established by the Board in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. For this purpose, the Audit Committee performs several

functions, including, among others:

•

evaluates the performance of and assesses the qualifications of the independent auditors;

•

determines and approves the engagement of the independent auditors;

•

determines whether to retain or terminate the existing independent auditors or to appoint and engage new independent auditors;

•

reviews and approves the retention of the independent auditors to perform any proposed permissible non-audit services;

•

monitors the rotation of partners of the independent auditors on the Company’s audit engagement team as required by law;

•

reviews and approves or rejects transactions between the company and any related persons;

•

confers with management and the independent auditors regarding the effectiveness of internal control over financial reporting;

•

establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; and

•

meets to review the Company’s annual audited financial statements and quarterly financial statements with management and the independent auditor, including a review of the Company’s disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

The Audit Committee is composed of three directors: Dr. Hirsch, Ms. Mackey and Mr. Schmid. Mr. Schmid serves as the chair of our Audit Committee. After the Annual Meeting, we expect the Audit Committee members to be Dr. Hirsch, Mr. Schmid and either Ms. Lloyd or Mr. Corning, with Mr. Schmid continuing as the chair of the Audit Committee. The Board has adopted a written Audit Committee charter that is available to stockholders on the Company’s website at www.poseida.com.

The Board of Directors reviews the Nasdaq listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Company’s Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing standards).

The Board of Directors has also determined that Mr. Schmid qualifies as an Audit Committee financial expert within the meaning of SEC regulations and meets the financial sophistication requirements of the Nasdaq Stock Market listing standards. In making this determination, our board has considered Mr. Schmid’s prior experience, business acumen and independence. Both our independent registered public accounting firm and management will periodically meet privately with our Audit Committee.

Report of the Audit Committee of the Board of Directors*

The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2020 with management of the Company. The Audit Committee has discussed with PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm, the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee has also received the written disclosures and the letter from PricewaterhouseCoopers LLP required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Mr. John P. Schmid (Chair)

Dr. David Hirsch.

Dr. Catherine J. Mackey

* The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of the Company under the Exchange Act or the Securities Act of 1933, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

Compensation Committee

The Compensation Committee is composed of three directors: Ms. Lloyd, Dr. Mackey and Mr. Murphy. Dr. Mackey serves as the chair of our Compensation Committee. After the Annual Meeting, we expect the Compensation Committee members to be Dr. Hirsch and Ms. Lloyd, with Dr. Hirsch serving as the chair of our Compensation Committee. All members of the Compensation Committee are independent (as independence is currently defined in Rule 5605(d)(2) of the Nasdaq listing standards). The Board has adopted a written Compensation Committee charter that is available to stockholders on the Company’s website at www.poseida.com.

The Compensation Committee of the Board of Directors acts on behalf of the Board to review, recommend for adoption and oversee the Company’s compensation strategy, policies, plans and programs, including:

•

establishment of corporate and individual performance objectives relevant to the compensation of the Company’s executive officers, directors and other senior management and evaluation of performance in light of these stated objectives;

•

review and recommendation to the Board for approval of the compensation and other terms of employment or service, including severance and change-in-control arrangements, of the Company’s Chief Executive Officer and the other executive officers and directors; and

•

administration of the Company’s equity compensation plans, pension and profit-sharing plans, deferred compensation plans and other similar plan and programs.

Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets at least quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chairperson of the Compensation Committee, in consultation with the Chief Executive Officer, Chief Human Resources Officer and the Company’s compensation consultant. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

In 2020, the Compensation Committee engaged an independent compensation consultant, Radford, an Aon Hewitt company (“Radford”), to advise the Company on executive and director compensation matters. Radford reports directly to the Compensation Committee and coordinates with our management for data collection and job matching for our executive officers. During 2020, Radford specifically advised the Compensation Committee regarding executive and director pay levels, including both cash and equity; review and analysis of market practice for option granting policy and overall strategy; and other compensation matters as requested throughout the year. To assist in determining executive compensation in 2020, Radford and the Compensation Committee reviewed a peer group of publicly traded companies in the life sciences industry at a stage of development, market capitalization, and size comparable to the Company. The Compensation Committee believed

that these companies were generally comparable to the Company and that the Company competed with these companies for executive talent.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee (the “Nominating Committee”) of the Board of Directors is responsible for identifying, reviewing and evaluating candidates to serve as directors of the Company (consistent with criteria approved by the Board), reviewing and evaluating incumbent directors, selecting or recommending to the Board for selection, candidates for election to the Board of Directors, making recommendations to the Board regarding the membership of the committees of the Board and developing a set of corporate governance principles for the Company.

The current members of the Nominating Committee are Ms. Lloyd, Mr. Murphy and Mr. Schmid. After the Annual Meeting we expect Nominating Committee members to be Ms. Lloyd and Mr. Schmid. Our Board has determined that each of the members of the Nominating Committee is independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards). Ms. Lloyd serves as the chair of our Nominating Committee. The Board has adopted a written Nominating Committee charter that is available to stockholders on the Company’s website and www.poseida.com.

The Nominating Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominating Committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of the Company’s stockholders. However, the Nominating Committee retains the right to modify these qualifications from time to time. Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of stockholders. In conducting this assessment, the Nominating Committee typically considers diversity (including gender, racial and ethnic diversity), age, skills and such other factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability.

The Nominating Committee appreciates the value of thoughtful Board refreshment, and regularly identifies and considers qualities, skills and other director attributes that would enhance the composition of the Board. In the case of incumbent directors whose terms of office are set to expire, the Nominating Committee reviews these directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. The Nominating Committee also takes into account the results of the Board’s self-evaluation, conducted annually on a group and individual basis and every three years, conducted with an outside consultant. In the case of new director candidates, the Nominating Committee also determines whether the nominee is independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote.

The Nominating Committee will consider director candidates recommended by stockholders. The Nominating Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating Committee no later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting at 9390 Towne Centre Drive, Suite 200, San Diego, California 92121, Attention: Corporate Secretary. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating stockholder is a beneficial or record holder of the Company’s stock. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

Stockholder Communications with the Board of Directors

The Company’s Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed to: 9390 Towne Centre Drive, Suite 200, San Diego, California 92121, Attention: Corporate Secretary. Such written communications must set forth the name and address of the stockholder on whose behalf the communication is sent and the number of shares of our capital stock that are owned beneficially by such stockholder as of the date of the communication. All communications will be compiled by our Corporate Secretary and submitted to the Board or the individual directors on a periodic basis.

These communications will be reviewed by our Corporate Secretary, who will determine whether the communication should be presented to the Board. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications). The screening procedures have been approved by a majority of the independent directors.

Code of Business Conduct and Ethics

The Company has adopted the Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on the Company’s website at www.poseida.com. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website.

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has selected PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2021 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. PricewaterhouseCoopers LLP has audited the Company’s financial statements since 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 the Company’s Bylaws nor other governing documents or law require stockholder ratification of the selection of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm. However, the Audit Committee of the Board of Directors 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 of the Board of Directors will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board of Directors in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the shares present at the Annual Meeting or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of accounting firm.

Principal Accountant Fees and Services

The following table represents aggregate fees for professional services for the fiscal years ended December 31, 2020 and 2019 rendered by PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm.

(2)	Tax fees consist of fees for professional services, primarily including tax consulting and compliance services.

(3)	All other fees include fees for include fees for professional services that are appropriately not included in the Audit, Audit Related, and Tax categories. All other fees for the fiscal years ended December 31, 2020 and 2019 were related to annual subscription to accounting literature and tools.

All of the services related to the fees described above were pre-approved by the Audit Committee.

Pre-Approval Policies and Procedures.

The Audit Committee has adopted policies and procedures for the pre-approval of audit and non-audit services rendered by the Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. 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 has determined that the rendering of services other than audit services by PricewaterhouseCoopers LLP is compatible with maintaining the principal accountant’s independence.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” PROPOSAL 2.

The annual performance-based bonus each named executive officer is eligible to receive is generally based on the extent to which we achieve the corporate goals that our Board of Directors or Compensation Committee establishes each year.

Potential Payments upon Termination or Change in Control

Regardless of the manner in which a named executive officer’s service terminates, each named executive officer is entitled to receive amounts previously earned during his term of service, including unpaid salary and cash out of unused vacation.

Each of our named executive officers is eligible to receive benefits under the terms of our Severance and Change in Control Plan adopted by the Board of Directors in June 2020 (the “Severance Plan”). The Severance Plan provides for severance and/or change in control benefits to the named executive officers upon (i) a “change in control termination” or (ii) a “regular termination” (each as described below). Upon a change in control termination, each of our named executive officers is entitled to a lump sum payment equal to a portion of his base salary (18 months for Dr. Ostertag and 12 months for each of Mr. Gergen and Mr. Leonhardt, a lump sum payment equal to his target cash bonus, accelerated vesting of outstanding time-vesting equity awards, payment of COBRA premiums for a period of time (up to 18 months for Dr. Ostertag and 12 months for each of Mr. Gergen and Mr. Leonhardt) and, for Dr. Ostertag an extension of the post-termination exercise period applicable to Dr. Ostertag’s outstanding equity awards for up to 24 months following such termination. To the extent an equity award is not assumed, continued or substituted for in the event of certain change in control transactions and the executive’s employment is not terminated as of immediately prior to such change in control, the vesting of such equity award will also accelerate in full (and for equity awards subject to performance vesting, performance will be deemed to be achieved at target, unless otherwise provided in individual award documents). Upon a regular termination, each of our named executive officers is entitled to a lump sum payment equal to a portion of his base salary (12 months for Dr. Ostertag and 9 months for each of Mr. Gergen and Mr. Leonhardt) and payment of COBRA premiums for a period of time (12 months for Dr. Ostertag and 9 months for each of Mr. Gergen and Mr. Leonhardt). All severance benefits under the Severance Plan are subject to the executive’s execution of an effective release of claims against the company.

For purposes of the Severance Plan, a “regular termination” is an involuntary termination (i.e., a termination other than for cause (and not as a result of death or disability) or a resignation for good reason, as defined in the Severance Plan) that does not occur during the period of time beginning one month prior to, and ending 12 months following, a “change in control” (as defined in the Company’s 2020 Equity Incentive Plan (the “2020 Plan”)), or the “change in control period.” A “change in control termination” is a regular termination that occurs during the change in control period.

In addition, pursuant to his employment agreement, Dr. Ostertag is entitled to certain tax gross-up payments with respect to any benefits he receives in connection with a change in control.

Other Compensation

Our named executive officers are eligible to participate in our health and welfare plans to the same extent as all full-time employees generally. We generally do not provide our named executive officers with significant perquisites or other personal benefits.

Our named executive officers did not participate in, or earn any benefits under, a nonqualified deferred compensation plan sponsored by us during the fiscal year ended December 31, 2020. Our Board of Directors may elect to provide our officers and other employees with nonqualified defined contribution or other nonqualified deferred compensation benefits in the future if it determines that doing so is in our best interests.

We have established a 401(k) tax-deferred savings plan, which permits participants, including our named executive officers, to make contributions by salary deduction pursuant to Section 401(k) of the Internal Revenue Code of 1986, as amended. We are responsible for administrative costs of the 401(k) plan. For 2020, we matched 50% of the first 6% of the participant’s

eligible compensation contributed to the 401(k) plan, up to a cap of $8,550. Matching contributions vest annually over the first 4 years of service and are fully vested thereafter.

Equity Plans

2020 Equity Incentive Plan

Our board of directors adopted, and our stockholders approved, our 2020 Plan in July 2020. Our 2020 Plan became effective on July 9, 2020, and is the successor to and continuation of our 2015 Plan. As of December 31, 2020, option awards covering an aggregate of 1,018,735 shares of our common stock granted under the 2020 Plan were outstanding.

Awards. Our 2020 Plan provides for the grant of incentive stock options, or ISOs, within the meaning of Section 422 of the Code, to employees, including employees of any parent or subsidiary, and for the grant of nonstatutory stock options, or NSOs, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards and other forms of awards to employees, directors and consultants, including employees and consultants of our affiliates.

Authorized Shares. Initially, the maximum number of shares of our common stock that may be issued under our 2020 Plan is 11,183,476 shares, which is the sum of (1) 4,500,000 new shares, plus (2) the number of shares that remain available for the issuance of awards under our 2015 Plan at the time our 2020 Plan became effective, plus (3) any shares subject to outstanding stock options or other stock awards that were granted under our 2015 Plan that terminate or expire prior to exercise or settlement; are settled in cash; are forfeited because of the failure to vest; or are reacquired or withheld (or not issued) to

satisfy a tax withholding obligation or the purchase or exercise price, if any, as such shares become available from time to time. In addition, the number of shares of our common stock reserved for issuance under our 2020 Plan will automatically increase on January 1 of each calendar year, starting on January 1, 2021 through January 1, 2030, in an amount equal to the lesser of (1) 5% of the total number of shares of our common stock outstanding on the last day of the calendar month before the date of each automatic increase, or (2) a lesser number of shares determined by our board of directors prior to the applicable January 1st. The maximum number of shares of our common stock that may be issued on the exercise of ISOs under our 2020 Plan is 33,550,428 shares.

Shares subject to stock awards granted under our 2020 Plan that expire or terminate without being exercised in full or that are paid out in cash rather than in shares do not reduce the number of shares available for issuance under our 2020 Plan. Shares withheld under a stock award to satisfy the exercise, strike or purchase price of a stock award or to satisfy a tax withholding obligation do not reduce the number of shares available for issuance under our 2020 Plan. If any shares of common stock issued pursuant to a stock award are forfeited back to or repurchased or reacquired by us for any reason, the shares that are forfeited or repurchased or reacquired will revert to and again become available for issuance under the 2020 Plan. Any shares previously issued which are reacquired in satisfaction of tax withholding obligations or as consideration for the exercise or purchase price of a stock award will again become available for issuance under the 2020 Plan.

The maximum number of shares of common stock subject to stock awards granted under the 2020 Plan or otherwise during any period commencing on the date of the company’s annual meeting of stockholders for a particular year and ending on the day immediately prior to the date of the company’s annual meeting of stockholders for the next subsequent year to any non-employee director, taken together with any cash fees paid by us to such non-employee director during such period for service on the board of directors, will not exceed $750,000 in total value (calculating the value of any such stock awards based on the grant date fair value of such stock awards for financial reporting purposes), or, with respect to the period in which a non-employee director is first appointed or elected to our board of directors, $1,000,000.

Plan Administration. Our board of directors, or a duly authorized committee of our board of directors, will administer our 2020 Plan and is referred to as the “plan administrator” herein. Our board of directors may also delegate to one or more of our officers the authority to (1) designate employees (other than officers) to receive specified stock awards and (2) determine the number of shares subject to such stock awards. Under our 2020 Plan, our board of directors has the authority to determine award recipients, grant dates, the numbers and types of stock awards to be granted, the applicable fair market value, and the provisions of each stock award, including the period of exercisability and the vesting schedule applicable to a stock award.

Under the 2020 Plan, the board of directors also generally has the authority to effect, with the consent of any materially adversely affected participant, (1) the reduction of the exercise, purchase, or strike price of any outstanding award; (2) the cancellation of any outstanding award and the grant in substitution therefore of other awards, cash, or other consideration; or (3) any other action that is treated as a repricing under generally accepted accounting principles.

Stock Options. ISOs and NSOs are granted under stock option agreements adopted by the plan administrator. The plan administrator determines the exercise price for stock options, within the terms and conditions of the 2020 Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of our common stock on the date of grant. Options granted under the 2020 Plan vest at the rate specified in the stock option agreement as determined by the plan administrator.

The plan administrator determines the term of stock options granted under the 2020 Plan, up to a maximum of 10 years. Unless the terms of an optionholder’s stock option agreement provide otherwise, if an optionholder’s service relationship with us or any of our affiliates ceases for any reason other than disability, death, or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. This period may be extended in the event that exercise of the option is prohibited by applicable securities laws. If an optionholder’s service relationship with us or any of our affiliates ceases due to death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of 18 months following the date of death. If an optionholder’s service relationship with us or any of our affiliates ceases due to disability, the optionholder may generally exercise any vested options for a period of 12 months following the cessation of service. In the event of a termination for cause, options generally terminate upon the termination date. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (1) cash, check, bank draft or money order, (2) a broker-assisted cashless exercise, (3) the tender of shares of our common stock previously owned by the optionholder, (4) a net exercise of the option if it is an NSO, or (5) other legal consideration approved by the plan administrator.

Tax Limitations on ISOs. The aggregate fair market value, determined at the time of grant, of our common stock with respect to ISOs that are exercisable for the first time by an award holder during any calendar year under all of our stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of our total combined voting power or that of any of our affiliates unless (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant, and (2) the term of the ISO does not exceed five years from the date of grant.

Restricted Stock Unit Awards. Restricted stock unit awards are granted under restricted stock unit award agreements adopted by the plan administrator. Restricted stock unit awards may be granted in consideration for any form of legal consideration that may be acceptable to our board of directors and permissible under applicable law. A restricted stock unit award may be settled by cash, delivery of stock, a combination of cash and stock as deemed appropriate by the plan administrator, or in any other form of consideration set forth in the restricted stock unit award agreement. Additionally, dividend equivalents may be credited in respect of shares covered by a restricted stock unit award. Except as otherwise provided in the applicable award agreement, restricted stock unit awards that have not vested will be forfeited once the participant’s continuous service ends for any reason.

Restricted Stock Awards. Restricted stock awards are granted under restricted stock award agreements adopted by the plan administrator. A restricted stock award may be awarded in consideration for cash, check, bank draft or money order, past or future services to us, or any other form of legal consideration that may be acceptable to our board of directors and permissible under applicable law. The plan administrator determines the terms and conditions of restricted stock awards, including vesting and forfeiture terms. If a participant’s service relationship with us ends for any reason, we may receive any or all of the shares of common stock held by the participant that have not vested as of the date the participant terminates service with us through a forfeiture condition or a repurchase right.

Stock Appreciation Rights. Stock appreciation rights are granted under stock appreciation right agreements adopted by the plan administrator. The plan administrator determines the purchase price or strike price for a stock appreciation right, which generally cannot be less than 100% of the fair market value of our common stock on the date of grant. A stock appreciation right granted under the 2020 Plan vests at the rate specified in the stock appreciation right agreement as determined by the plan administrator. Stock appreciation rights may be settled in cash or shares of common stock.

The plan administrator determines the term of stock appreciation rights granted under the 2020 Plan, up to a maximum of 10 years. If a participant’s service relationship with us or any of our affiliates ceases for any reason other than cause, disability, or death, the participant may generally exercise any vested stock appreciation right for a period of three months following the cessation of service. This period may be further extended in the event that exercise of the stock appreciation right following such a termination of service is prohibited by applicable securities laws. If a participant’s service relationship with us, or any of our affiliates, ceases due to disability or death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested stock appreciation right for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stock appreciation rights generally terminate immediately upon the occurrence of the event giving rise to the termination of the individual for cause. In no event may a stock appreciation right be exercised beyond the expiration of its term.

Performance Awards. The 2020 Plan permits the grant of performance awards that may be settled in stock, cash or other property. Performance awards may be structured so that the stock or cash will be issued or paid only following the achievement of certain pre-established performance goals during a designated performance period. Performance awards that

are settled in cash or other property are not required to be valued in whole or in part by reference to, or otherwise based on, the common stock.

The performance goals may be based any measure of performance selected by the board of directors. The performance goals may be based on company-wide performance or performance of one or more business units, divisions, affiliates, or business segments, and may be either absolute or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. Unless specified otherwise by the board of directors at the time the performance award is granted, the board will appropriately make adjustments in the method of calculating the attainment of performance goals as follows: (1) to exclude restructuring and/or other nonrecurring charges; (2) to exclude exchange rate effects; (3) to exclude the effects of changes to generally accepted accounting principles; (4) to exclude the effects of any statutory adjustments to corporate tax rates; (5) to exclude the effects of items that are “unusual” in nature or occur “infrequently” as determined under generally accepted accounting principles; (6) to exclude the dilutive effects of acquisitions or joint ventures; (7) to assume that any portion of our business which is divested achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; (8) to exclude the effect of any change in the outstanding shares of our common stock by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions to common stockholders other than regular cash dividends; (9) to exclude the effects of stock based compensation and the award of bonuses under our bonus plans; (10) to exclude costs incurred in connection with potential acquisitions or divestitures that are required to be expensed under generally accepted accounting principles; and (11) to exclude the goodwill and intangible asset impairment charges that are required to be recorded under generally accepted accounting principles.

Other Stock Awards. The plan administrator may grant other awards based in whole or in part by reference to our common stock. The plan administrator will set the number of shares under the stock award (or cash equivalent) and all other terms and conditions of such awards.

Changes to Capital Structure. In the event there is a specified type of change in our capital structure, such as a stock split, reverse stock split, or recapitalization, appropriate adjustments will be made to (1) the class and maximum number of shares reserved for issuance under the 2020 Plan, (2) the class and maximum number of shares by which the share reserve may increase automatically each year, (3) the class and maximum number of shares that may be issued on the exercise of ISOs, and (4) the class and number of shares and exercise price, strike price, or purchase price, if applicable, of all outstanding stock awards.

Corporate Transactions. The following applies to stock awards under the 2020 Plan in the event of a corporate transaction (as defined in the 2020 Plan), unless otherwise provided in a participant’s stock award agreement or other written agreement with us or one of our affiliates or unless otherwise expressly provided by the plan administrator at the time of grant. In the event of a corporate transaction, any stock awards outstanding under the 2020 Plan may be assumed, continued or substituted for by any surviving or acquiring corporation (or its parent company), and any reacquisition or repurchase rights held by us with respect to the stock award may be assigned to the successor (or its parent company). If the surviving or acquiring corporation (or its parent company) does not assume, continue or substitute for such stock awards, then (1) with respect to any such stock awards that are held by participants whose continuous service has not terminated prior to the effective time of the corporate transaction, or current participants, the vesting (and exercisability, if applicable) of such stock awards will be accelerated in full to a date prior to the effective time of the corporate transaction (contingent upon the effectiveness of the corporate transaction), and such stock awards will terminate if not exercised (if applicable) at or prior to the effective time of the corporate transaction, and any reacquisition or repurchase rights held by us with respect to such stock awards will lapse (contingent upon the effectiveness of the corporate transaction), and (2) any such stock awards that are held by persons other than current participants will terminate if not exercised (if applicable) prior to the effective time of the corporate transaction, except that any reacquisition or repurchase rights held by us with respect to such stock awards will not terminate and may continue to be exercised notwithstanding the corporate transaction.

In the event a stock award will terminate if not exercised prior to the effective time of a corporate transaction, the plan administrator may provide, in its sole discretion, that the holder of such stock award may not exercise such stock award but instead will receive a payment equal in value to the excess (if any) of (1) the per share amount payable to holders of common stock in connection with the corporate transaction, over (2) any per share exercise price payable by such holder provided in the stock award, if applicable. In addition, any escrow, holdback, earn out or similar provisions in the definitive agreement

for the corporate transaction may apply to such payment to the same extent and in the same manner as such provisions apply to the holders of common stock.

Under the 2020 Plan, a corporate transaction is generally the consummation of: (1) a sale of all or substantially all of our assets, (2) the sale or disposition of more than 50% of our outstanding securities, (3) a merger or consolidation where we do not survive the transaction, or (4) a merger or consolidation where we do survive the transaction but the shares of our common stock outstanding immediately before such transaction are converted or exchanged into other property by virtue of the transaction.

Change in Control. Awards granted under the 2020 Plan may be subject to acceleration of vesting and exercisability upon or after a change in control as may be provided in the applicable stock award agreement or in any other written agreement between us or any affiliate and the participant, but in the absence of such provision, no such acceleration will automatically occur. Under the 2020 Plan, a change in control is generally (1) the acquisition by any person or company of more than 50% of the combined voting power of our then outstanding stock, (2) a merger, consolidation or similar transaction in which our stockholders immediately before the transaction do not own, directly or indirectly, more than 50% of the combined voting power of the surviving entity (or the parent of the surviving entity) in substantially the same proportions as their ownership immediately prior to such transaction, (3) a sale, lease, exclusive license or other disposition of all or substantially all of our assets other than to an entity more than 50% of the combined voting power of which is owned by our stockholders in substantially the same proportions as their ownership of our outstanding voting securities immediately prior to such transaction, or (4) when a majority of our board of directors becomes comprised of individuals who were not serving on our board of directors on the date of the underwriting agreement related to this offering, or the incumbent board, or whose nomination, appointment, or election was not approved by a majority of the incumbent board still in office.

Plan Amendment or Termination. Our board of directors has the authority to amend, suspend, or terminate our 2020 Plan, provided that such action does not materially impair the existing rights of any participant without such participant’s written consent. Certain material amendments also require the approval of our stockholders. No ISOs may be granted after the tenth anniversary of the date our board of directors adopts our 2020 Plan. No stock awards may be granted under our 2020 Plan while it is suspended or after it is terminated.

2015 Equity Incentive Plan

Our board of directors adopted our 2015 Equity Incentive Plan (the “2015 Plan”), in February 2015, and our stockholders approved our 2015 Plan in May 2015. In July 2020, upon the effective date of the 2020 Plan, the 2015 Plan ceased to be available for new grants of equity awards, and any shares remaining available for issuance under the 2015 Plan became available for issuance under the 2020 Plan. As of December 31, 2020, there were outstanding stock options covering a total of 3,719,872 shares of our common stock that were granted under our 2015 Plan. Our board of directors, or a duly authorized committee thereof, administers the 2015 Plan and is referred to as the “plan administrator” herein.

Stock Options. ISOs and NSOs are granted under stock option agreements adopted by the plan administrator. The plan administrator determines the exercise price for stock options, within the terms and conditions of the 2015 Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of our common stock on the date of grant (or 110% of the fair market value for certain major stockholders). Options granted under the 2015 Plan vest at the rate specified in the stock option agreement as determined by the plan administrator.

The plan administrator determines the term of stock options granted under the 2015 Plan, up to a maximum of 10 years (or five years, for certain major stockholders). If an optionholder’s service relationship with us or any of our affiliates ceases for any reason other than disability, death or cause, the optionholder may generally exercise any vested options for a period of up to three months following the cessation of service. This period may be extended in the event that exercise of the option is prohibited by applicable securities laws or our insider trading policy.

If an optionholder’s service relationship with us or any of our affiliates ceases due to death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of up to 18 months following the date of death. If an optionholder’s service relationship with us or any of our affiliates ceases due to disability, the optionholder may generally exercise any vested options for a period of up to 12 months following the cessation of service. In the event of a termination for cause, options generally terminate upon the termination date. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (1) cash, check, bank draft or money order payable to us, (2) a broker-assisted cashless exercise, (3) the tender of shares of our common stock previously owned by the optionholder, (4) a net exercise of the option if it is an NSO, (5) a deferred payment arrangement, or (6) other legal consideration approved by the plan administrator.

Unless the plan administrator provides otherwise, options generally are not transferable except by will or the laws of descent and distribution. Subject to approval of the plan administrator or a duly authorized designee in each case, (1) an option may be transferred pursuant to a domestic relations order and (2) an optionholder may designate a beneficiary who may exercise the option following the optionholder’s death.

Corporate Transactions. Our 2015 Plan provides that in the event of a corporate transaction, unless otherwise provided in an award agreement or other written agreement between us and the award holder, the plan administrator may take one or more of the following actions with respect to such stock awards:

•

arrange for the assumption, continuation, or substitution of a stock award by a surviving or acquiring corporation;

•

arrange for the assignment of any reacquisition or repurchase rights held by us to the surviving or acquiring corporation;

•

accelerate the vesting, in whole or in part, of the stock award and provide for its termination if not exercised (if applicable) at or before the effective time of the transaction;

•

arrange for the lapse of any reacquisition or repurchase rights held by us with respect to the stock award;

•

cancel or arrange for the cancellation of the stock award, to the extent not vested or exercised before the effective time of the transaction, in exchange for such cash consideration, if any, as the board of directors may consider appropriate; and

•

make a payment equal to the excess, if any, of (1) the value of the property the participant would have received on exercise of the award, over (2) any exercise price payable by the participant in connection with the exercise.

The plan administrator is not obligated to treat all stock awards in the same manner and is not obligated to treat all participants in the same manner.

Under the 2015 Plan, a corporate transaction is generally defined as the consummation, in a single transaction or in a series of related transactions, of: (1) a sale or other disposition of all or substantially all of our assets, (2) the sale or disposition of at least 50% of our outstanding securities, (3) a merger or consolidation where we do not survive the transaction, or (4) a merger, consolidation or similar transaction where we do survive the transaction but the shares of our common stock outstanding immediately before such transaction are converted or exchanged into other property by virtue of the transaction.

Change in Control. A stock award may be subject to additional acceleration of vesting and exercisability upon or after a change in control as may be provided in an applicable award agreement or other written agreement, but in the absence of such provision, no such acceleration will occur. Under the 2015 Plan, a change in control is generally defined as (1) the acquisition by a person or entity of more than 50% of the combined voting power of our then outstanding stock other than by merger, consolidation or similar transaction, (2) a consummated merger, consolidation or similar transaction in which our stockholders immediately before the transaction do not own, directly or indirectly, more than 50% of the combined voting power of the surviving entity (or the parent of the surviving entity) in substantially the same proportions as their ownership immediately prior to such transaction, or (3) a consummated sale, lease, exclusive license or other disposition of all or substantially all of our consolidated assets other than to an entity more than 50% of the combined voting power of which is owned by our stockholders in substantially the same proportions as their ownership of our outstanding voting securities immediately prior to such transaction.

2020 Employee Stock Purchase Plan

Our board of directors adopted, and our stockholders approved, our 2020 Employee Stock Purchase Plan (“2020 ESPP”), in July 2020. The 2020 ESPP became effective on July 9, 2020. The purpose of the 2020 ESPP is to secure the services of new employees, to retain the services of existing employees, and to provide incentives for such individuals to exert maximum efforts toward our success and that of our affiliates. The 2020 ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Code for U.S. employees.

Share Reserve. The 2020 ESPP initially authorizes the issuance of up to 615,000 shares of our common stock under purchase rights granted to our employees or to employees of any of our designated affiliates. The number of shares of our common stock reserved for issuance will automatically increase on January 1 of each calendar year, beginning on January 1, 2021 through January 1, 2030, by the lesser of (1) 1% of the total number of shares of our common stock outstanding on the last day of the calendar month before the date of the automatic increase, and (2) 1,230,000 shares; provided that before the date of any such increase, our board of directors may determine that such increase will be less than the amount set forth in clauses (1) and (2). As of the date hereof, no shares of our common stock have been purchased under the 2020 ESPP.

Administration. Our board of directors, or a duly authorized committee of our board of directors, will administer the 2020 ESPP. The 2020 ESPP is implemented through a series of offerings under which eligible employees are granted purchase rights to purchase shares of our common stock on specified dates during such offerings. Under the 2020 ESPP, we may specify offerings with durations of not more than 27 months, and may specify shorter purchase periods within each offering. Each offering will have one or more purchase dates on which shares of our common stock will be purchased for employees participating in the offering. An offering under the 2020 ESPP may be terminated under certain circumstances.

Payroll Deductions. Generally, all regular employees, including executive officers, employed by us or by any of our designated affiliates, may participate in the 2020 ESPP and may contribute, normally through payroll deductions, up to 15% of their earnings (as defined in the 2020 ESPP) for the purchase of our common stock under the 2020 ESPP. Unless otherwise determined by our board of directors (and subject to certain limitations in the 2020 ESPP and under the Code), common stock will be purchased for the accounts of employees participating in the 2020 ESPP at a price per share that is at least the lesser of (1) 85% of the fair market value of a share of our common stock on the first date of an offering, or (2) 85% of the fair market value of a share of our common stock on the date of purchase.

Corporate Transactions. In the event of certain significant corporate transactions, any then-outstanding rights to purchase our stock under the 2020 ESPP may be assumed, continued, or substituted for by any surviving or acquiring entity (or its parent company). If the surviving or acquiring entity (or its parent company) elects not to assume, continue, or substitute for such purchase rights, then the participants’ accumulated payroll contributions will be used to purchase shares of our common stock within 10 business days before such corporate transaction, and such purchase rights will terminate immediately.

Under the 2020 ESPP, a corporate transaction is generally the consummation of: (1) a sale of all or substantially all of our assets, (2) the sale or disposition of more than 50% of our outstanding securities, (3) a merger or consolidation where we do not survive the transaction, and (4) a merger or consolidation where we do survive the transaction but the shares of our common stock outstanding immediately before such transaction are converted or exchanged into other property by virtue of the transaction.

2020 ESPP Amendment or Termination. Our board of directors has the authority to amend or terminate our 2020 ESPP, provided that except in certain circumstances such amendment or termination may not materially impair any outstanding purchase rights without the holder’s consent. We will obtain stockholder approval of any amendment to our 2020 ESPP as required by applicable law or listing requirements.

In accordance with SEC rules, this column reflects the aggregate grant date fair value of the stock option awards granted during 2020. This amount has been computed in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 718, “Compensation - Stock Compensation”. Assumptions used in the calculation of this amount are described in Note 9 to the Consolidated Financial Statements included in our Annual Report filed on Form 10-K filed with the SEC on March 11, 2021, for the fiscal year ended December 31, 2020. This amount does not reflect the actual economic value that will be realized upon the vesting of the stock options, the exercise of the stock options, or the sale of the common stock underlying such stock options.

(2)	As of December 31, 2020, the aggregate number of shares underlying outstanding options to purchase our common stock held by our non-employee directors were: Mr. Schmid, 68,115, Ms. Lloyd, 68,115, Dr. Mackey, 68,115, Dr. Hirsch, 20,000 and

Mr. Murphy, 20,000 and Mr. Corning did not hold any options to purchase shares of our common stock. As of December 31, 2020, none of our non-employee directors held other unvested stock awards.

(3)	Mr. Corning elected not to receive the compensation to which he would otherwise be entitled in accordance with the Company’s Non-Employee Director Compensation Policy.

We have reimbursed and will continue to reimburse all of our non-employee directors for their reasonable out-of-pocket costs and expenses incurred in connection with attending board meetings.

Our Board of Directors adopted a non-employee director compensation policy that became effective in July 2020 in connection with our initial public offering and is applicable to all of our non-employee directors. This compensation policy provides that each such non-employee director will receive the following compensation for service on our Board of Directors:

•

an annual cash retainer of $40,000;

•

an additional annual cash retainer of $30,000 for service as independent chair of the Board of Directors;

•

an additional annual cash retainer of $20,000 for service as lead independent director;

•

an additional annual cash retainer of $7,500, $5,000 and $4,000 for service as a member of the Audit Committee, Compensation Committee and the Nominating and Corporate Governance Committee, respectively;

•

an additional annual cash retainer of $15,000, $10,000 and $8,000 for service as chair of the Audit Committee, chair of the Compensation Committee and chair of the Nominating and Corporate Governance Committee, respectively (in lieu of the committee member retainer above);

•

an initial option grant to purchase 40,000 shares of our common stock, vesting in 36 equal monthly installments; and

•

an annual option grant to purchase 20,000 shares of our common stock, vesting on the earlier of (i) the one year anniversary of the date of grant and (ii) the day before the next annual meeting.

Each of the option grants described above will be granted under our 2020 Plan. Each option grant will vest in full upon a change in control. The term of each option will be ten years, subject to earlier termination as provided in the 2020 Plan, provided that upon a termination of service other than for death, disability or cause, the post-termination exercise period will be 12 months from the date of termination.

TRANSACTIONS WITH RELATED PERSONS AND INDEMNIFICATION

The following includes a summary of transactions since January 1, 2019 to which we have been a party in which the amount involved exceeded or will exceed the lesser of $120,000 or 1% of our total assets as of our last two completed fiscal years, and in which any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our capital stock, including any of their immediate family members and affiliates, including entities owned or controlled by such persons, had or will have a direct or indirect material interest, other than equity and other compensation, termination, change in control and other arrangements, which are described under “Executive Compensation” and “Director Compensation.”

Directed Share Program

We closed our initial public offering in July 2020. At our request, the underwriters reserved for sale at the initial public offering price per share a certain number of shares for sale to certain of our directors and other early supporters of Poseida Therapeutics, Inc. identified by management through a directed share program. Ms. Lloyd and Mr. Murphy who served as our directors in 2020 participated in the directed share program and each purchased 10,000 shares of our common stock at a purchase price of $16.00 per share.

Investor Agreements

In connection with our preferred stock financings, we entered into an amended and restated investor rights agreement, amended and restated voting agreement and amended and restated right of first refusal and co-sale agreement containing voting rights, information rights, rights of first refusal and co-sale and registration rights, among other things, with certain of our stockholders. These rights, except for the registration rights contained in the amended and restated investor rights agreement, terminated upon the completion of our initial public offering in July 2020.

Management Rights Letters

In connection with our sale of our preferred stock, we entered into management rights letters with certain purchasers of our preferred stock, including holders of more than 5% of our capital stock and entities with which certain of our directors are

affiliated, pursuant to which such entities were granted certain management rights, including the right to consult with and advise our management on significant business issues, review our operating plans, examine our books and records and inspect our facilities. These management rights terminated upon the completion of our initial public offering in July 2020.

Indemnification Agreements

The Company provides indemnification for its directors and officers so that they will be free from undue concern about personal liability in connection with their service to the Company. Our amended and restated certificate of incorporation contains provisions limiting the liability of directors and under the Company’s Bylaws, the Company is required to indemnify its directors and officers to the extent not prohibited under Delaware or other applicable law. The Company has also entered into indemnity agreements with certain officers and directors. These agreements provide, among other things, that the Company will indemnify the officer or director, under the circumstances and to the extent provided for in the agreement, for expenses, damages, judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by reason of his or her position as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under Delaware law and the Company’s Bylaws.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other annual meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are Company stockholders will be “householding” the Company’s proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that 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 a separate Notice of Internet Availability of Proxy Materials, please notify your broker or the Company by telephone at (858) 779-3100 or in writing at 9390 Towne Centre Drive, Suite 200, San Diego, California 92121, Attention: Corporate Secretary. Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.

The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting.
