PROXY STATEMENT

FOR THE 2022 ANNUAL MEETING OF STOCKHOLDERS

MAY 17, 2022

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, or 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, or the Notice, because the Board of Directors of Personalis, Inc., sometimes referred to as the Company or Personalis, is soliciting your proxy to vote at the 2022 Annual Meeting of Stockholders, or the 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 or about April 1, 2022 to all stockholders of record entitled to vote at the Annual Meeting.

Will I receive any other proxy materials by mail?

No, you will not receive any other proxy materials by mail unless you request a paper copy of proxy materials. To request that a full set of the proxy materials be sent to your specified postal address, please go to www.ProxyVote.com or call 1-800-579-1639 or send an email to sendmaterial@proxyvote.com. Please have your proxy card in hand when you access the website or call and follow the instructions provided.

How do I attend the Annual Meeting?

The meeting will be held virtually via live webcast at www.virtualshareholdermeeting.com/PSNL2022 on Tuesday, May 17, 2022 at 9:00 a.m. Pacific Time. Information on how to vote online at the Annual Meeting is discussed below.

We encourage you to access the Annual Meeting before it begins. Online check-in will start approximately 15 minutes before the meeting on May 17, 2022.

To be admitted to the Annual Meeting, you will need to visit www.virtualshareholdermeeting.com/PSNL2022 and enter the 16-digit Control Number found next to the label “Control Number” on your proxy card or voting instruction form, or in the email sending you the Proxy Statement. If you are a beneficial shareholder, you should contact the bank, broker or other institution where you hold your account well in advance of the meeting if you have questions about obtaining your control number/proxy to vote.

If you have difficulty accessing the meeting, please call the number listed on the stockholder login page where technicians will be available to help you.

For the Annual Meeting, how do we ask questions of management and the board?

We plan to have a Q&A session at the Annual Meeting and will include as many shareholder questions as the allotted time permits. Shareholders may submit questions that are relevant to our business in advance of the Annual Meeting as well as live during the Annual Meeting. If you are a shareholder, you may submit a question in advance of the meeting at www.ProxyVote.com after logging in with your Control Number. Questions may be submitted during the annual meeting through www.virtualshareholdermeeting.com/PSNL2022.

If I miss the Annual Meeting, will there be a copy posted online?

Yes, a replay of the Annual Meeting webcast will be made available approximately 24 hours after the meeting and remain available for at least one year. The replay can be accessed by visiting www.virtualshareholdermeeting.com/PSNL2022.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on March 18, 2022 will be entitled to vote at the Annual Meeting. On this record date, there were 45,184,940 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on March 18, 2022 your shares were registered directly in your name with our transfer agent, Computershare Trust Company, N.A., then you are a stockholder of record. As a stockholder of record, you may vote online at the Annual Meeting, vote by proxy through the internet or by telephone, 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 Annual Meeting, we urge you to vote by proxy through the internet or by telephone as instructed below, or by completing a proxy card that you may request or that we may elect to deliver at a later time.

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

If on March 18, 2022 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 online. However, since you are not the stockholder of record, you may not vote your shares online at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.

Will a list of record stockholders as of the record date be available?

A list of our record stockholders as of the close of business on the record date will be made available to stockholders during the Annual Meeting at www.virtualshareholdermeeting.com/PSNL2022.

In addition, for the ten days prior to the Annual Meeting, stockholders may request to view a list of stockholders of record for a legally valid purpose by sending an email to investors@personalis.com.

What am I voting on?

There are four matters scheduled for a vote:

•

Proposal 1 – To elect our Board of Directors’ two nominees for Class III director named herein to hold office until our 2025 Annual Meeting of Stockholders and until their successors have been duly elected and qualified.

•

Proposal 2 – To ratify the selection by the Audit Committee of the Board of Directors of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2022.

•

Proposal 3 – To approve, on a non-binding, advisory basis, the compensation of the Company’s named executive officers.

•

Proposal 4 – To approve, on a non-binding advisory basis, the preferred frequency of holding future advisory votes on the compensation of the Company’s named executive officers.

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 nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify. For Proposal 2 and Proposal 3, you may vote “For” or “Against” or abstain from voting. For Proposal 4, you may vote for “1 Year,” “2 Years,” “3 Years” 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 online during the webcast of the Annual Meeting, vote by proxy through the internet or by telephone, 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 Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote online even if you have already voted by proxy.

•

To vote at the Annual Meeting you must be present via live webcast. To vote through the internet during the meeting, go to www.virtualshareholdermeeting.com/PSNL2022. Follow the instructions and have the control number from the Notice.

•

To vote using the proxy card, simply complete, sign and date the proxy card that may be delivered 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 through the internet before the meeting, go to www.ProxyVote.com.com to complete an electronic proxy card. You will be asked to provide the company number and control number from the Notice. Your internet vote must be received by 11:59 p.m., Eastern Time on May 16, 2022 to be counted.

•

To vote over the telephone, dial toll-free 1-800-690-6903 using a touch-tone phone 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 by 11:59 p.m., Eastern Time on May 16, 2022 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 Personalis. Simply follow the voting instructions in the Notice to ensure that your vote is counted. To vote online at the Annual Meeting, you must obtain a valid proxy from your broker, bank or other agent.

Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.

Internet proxy voting may be 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 own as of March 18, 2022.

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 stockholder of record and do not vote by completing a 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” Proposal 1 – Election of Both Nominees for Director, “For” Proposal 2 – Ratification of Selection of Independent Registered Public Accounting Firm, “For” Proposal 3 – Say-on-Pay, and “3 Years” for Proposal 4 – Say-on-Pay Frequency. If any other matter is properly presented at the meeting, your proxyholder will vote your shares using their 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. 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. All brokers registered as members with the NYSE are subject to NYSE Rules and, accordingly, the NYSE Rules apply to the voting of all shares held in a brokerage account, including shares of a company like ours listed on Nasdaq. In this regard, the election of directors (Proposal 1), Say-on-Pay (Proposal 3), and Say-on-Pay Frequency (Proposal 4) are considered to be “non-routine” under NYSE rules, meaning that your broker may not vote your shares on this proposal in the absence of your voting instructions. However, the ratification of the selection of our independent registered public accounting firm (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. We encourage you to provide voting instructions to your bank, broker, or other nominee. This ensures that your shares will be voted at the Annual Meeting according to your instructions. You should receive directions from your bank, broker, or other nominee about how to submit your proxy to them at the time you receive this proxy statement.

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.

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 online, 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 our Corporate Secretary at 1330 O’Brien Drive, Menlo Park, California 94025.

•

You may attend the live webcast of the Annual Meeting and vote online. Simply attending the meeting will not, by itself, revoke your 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.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for Proposal 1, votes “For,” “Withhold” and broker non-votes; with respect to Proposal 2, votes “For” and “Against,” abstentions and, if applicable, broker non-votes; and with respect to Proposals 3 and 4, votes “For” and “Against,” abstentions and broker non-votes.

Abstentions will be counted towards the vote total for Proposals 2 and 3 and will have the same effect as “Against” votes. Abstentions will be counted towards the vote total for Proposal 4 and will have the same effect as votes “Against” each of the proposed voting frequencies. Broker non-votes will be counted for purposes of determining the presence of a quorum and will have no effect on 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 to be “non-routine,” the broker or nominee cannot vote the shares. These unvoted shares are counted as “broker non-votes.” Proposal 1, Proposal 3, and Proposal 4 are considered to be “non-routine” and we therefore expect broker non-votes to exist in connection with these proposals.

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 does the Board recommend that I vote and how many votes are needed to approve each proposal?


Proposal Number	Proposal Description	Board Recommendation	Vote Required for Approval	Effect of Withhold and Abstentions	Effect of Non-Broker Votes
1	Election of Class III Directors.	FOR both nominees	Nominees receiving the most “For” votes.	Under plurality voting, there are no abstentions. Withheld votes will have no effect.	None.
2	Ratification of the selection of Deloitte & Touche, LLP as the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2022.	FOR	“For” votes from the holders of a majority of shares present online or represented by proxy and entitled to vote on the matter.	Against.	None.
3	Approval, on a non-binding, advisory basis, the compensation of the Company’s named executive officers.	FOR	“For” votes from the holders of a majority of shares present online or represented by proxy and entitled to vote on the matter.	Against.	None.
4	Indication, on a non-binding advisory basis, the preferred frequency of holding future advisory votes on the compensation of the Company’s named executive officers.	3 years	“For” votes from the holders of a majority of shares present online or represented by proxy and entitled to vote on the matter.**	Against each of the proposed voting frequencies.	None.

This proposal is considered to be “routine” and therefore no broker non-votes are expected for this proposal.

If none of the proposed voting frequencies receives the votes of the holders of a majority of shares present virtually or represented by proxy and entitled to vote on the matter at the Annual Meeting, we will consider the frequency receiving the highest number of affirmative votes from the holders of shares present virtually or represented by proxy and entitled to vote at the Annual Meeting to be the frequency preferred by our stockholders.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if the holders of a majority of the voting power of the outstanding shares entitled to vote are present at the meeting online or represented by proxy. On the record date, there were 45,184,940 shares outstanding and entitled to vote. Thus, the holders of 22,592,471 shares must be present online 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 card (or one is submitted on your behalf by your broker, bank, or other nominee) or if you vote online at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the Chair of the meeting or the holders of a majority of shares present at the meeting online 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.

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

To be considered for inclusion in our proxy materials for our 2023 Annual Meeting of Stockholders, your proposal must be submitted in writing by Friday, December 2, 2022, to our Corporate Secretary at 1330 O’Brien Drive, Menlo Park, California 94025, and you must comply with all applicable requirements of Rule 14a-8 promulgated under the Securities Exchange Act of 1934, as amended (“the Exchange Act”). However, if the 2023 Annual Meeting of Stockholders is advanced by more than 30 days prior to or delayed by more than 30 days after May 17, 2023, then the deadline will be a reasonable time prior to the time we begin to print and send our proxy materials.

Pursuant to our Amended and Restated Bylaws, or our bylaws, if you wish to submit a proposal (including a director nomination) at the 2023 Annual Meeting of Stockholders that is intended to be included in next year’s proxy materials, you must do so not later than the close of business on Thursday, February 16, 2023 and no earlier than the close of business on Tuesday, January 17, 2023 provided, however, that if next year’s annual meeting is advanced by more than 30 days prior to or delayed by more than 30 days after May 17, 2023, your proposal must be submitted not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of such meeting is first made. You are advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations. In addition, the proxy solicited by our Board of Directors for the 2023 Annual Meeting will

confer discretionary voting authority with respect to (i) any proposal presented by a stockholder at that meeting for which Personalis has not been provided with timely notice and (ii) any proposal made in accordance with our bylaws, even if the 2023 proxy statement briefly describes the matter and how management proxy holders intend to vote on it, if the stockholder does not comply with the requirements of Rule 14a-4(c)(2) promulgated under the Exchange Act. In addition to satisfying the foregoing requirements under our bylaws, to comply with the universal proxy rules (once effective), stockholders who intend to solicit proxies in support of director nominees other than our Board’s nominees must provide notice that sets forth any additional information required by Rule 14a-19 promulgated under the Exchange Act no later than March 18, 2023.

PROPOSAL 1

ELECTION OF DIRECTORS

Our amended and restated certificate of incorporation provides for a classified board of directors (“Board of Directors”) consisting of three classes of directors. Currently, Class I and Class III each consist of three directors, and Class II consists of two directors. Each class serves for a three-year term. Vacancies on our Board of Directors may be filled only by persons elected by a majority of the remaining directors. A director elected by our 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.

Our Board of Directors currently is composed of eight directors. There are three directors whose term of office expires in 2022, two of which have been nominated for re-election as directors at the Annual Meeting; as a result, after the Annual Meeting, our Board of Directors will be composed of seven directors. Proxies may not be voted for a greater number of persons than the number of nominees named

Upon the recommendation of the Nominating and Corporate Governance Committee, our Board of Directors has nominated the two individuals listed in the table below for election as directors at the Annual Meeting. Mr. Bowman and Ms. Eastham were each previously elected to our Board of Directors prior to our initial public offering (our “IPO”), which was completed in June 2019. If the nominees listed below are elected, they will each hold office until the annual meeting of stockholders in 2025 and until each of their successors has been duly elected and qualified or, if sooner, until the director’s death, resignation or removal. All nominees are currently serving on our Board of Directors and have consented to being named in this proxy statement and to serve if elected. It is our policy to encourage directors and nominees for director to attend the Annual Meeting. All of our then-serving directors attended the Annual Meeting of our stockholders held in 2021.

The brief biographies below include information, as of the date of this proxy statement, regarding the specific and particular experience, qualifications, attributes or skills that led the Nominating and Corporate Governance Committee to believe that each director or nominee should serve on the Board of Directors. There are no family relationships among any of our executive officers or directors.

Vote Required

Directors are elected by a plurality of the votes of the holders of shares present online or represented by proxy and entitled to vote on the election of directors. Accordingly, the two nominees receiving the highest number of affirmative votes will be elected. You may not vote your shares cumulatively for the election of directors. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the two nominees named above. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by our Board of Directors. The Board of Directors has no reason to believe that any of the nominees would prove unable to serve if elected. There are no arrangements or understandings between us and any director, or nominee for directorship, pursuant to which such person was selected as a director or nominee.

The Board of Directors Recommends

a Vote “For” Each of the Nominees Named Above.

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS MATTERS

Overview

We are committed to exercising good corporate governance practices. In furtherance of this commitment, we regularly monitor developments in the area of corporate governance and review our processes, policies, and procedures in light of such developments. Key information regarding our corporate governance initiatives can be found on the Investors section of our website, www.personalis.com, including our Corporate Governance Guidelines, Code of Business Conduct and Ethics, and the charters for our Audit, Compensation, and Nominating and Corporate Governance Committees. We believe that our corporate governance policies and practices, including the substantial percentage of independent directors on our Board of Directors and the appointment of an independent Chair of the Board of Directors, empower our independent directors to effectively oversee our management—including the performance of our Chief Executive Officer—and provide an effective and appropriately balanced board governance structure.

Board Experience and Diversity

We believe in order to provide effective decision making and oversight of the Company, our Board of Directors’ experience and diversity is integral. As set forth in our Corporate Governance Guidelines, the Nominating and Corporate Governance Committee and our Board of Directors consider diversity, age, skills and such other factors as they deem appropriate given the current needs of our Board of Directors and the Company in identifying director nominees, the Nominating and Corporate Governance Committee and our Board of Directors believe that considering age, gender, and ethnic diversity is consistent with the goal of creating a board that best serves the needs of the Company and the interests of our stockholders. For example, two of our eight directors identify as female, and two of our eight directors identify as members of an “underrepresented community” as defined under California law and Nasdaq board diversity requirements. The Board Diversity Matrix, below, provides the diversity statistics for our Board of Directors.

Independence of the Board of Directors

As required under the 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. Our Board of Directors has undertaken a review of its composition, the composition of its committees, and

the independence of each director, including consultation with our outside counsel to ensure our Board of Directors 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. Based upon information requested from and provided by each director concerning his or her background, employment, and affiliations, including family relationships, our Board of Directors has determined that Mses. Bloom and Eastham, Messrs. Bowman and Ludlum, and Drs. Colowick and Myers do not have any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is otherwise “independent” as that term is defined under applicable Nasdaq listing standards. Mr. West is not considered independent because he currently serves as our Chief Executive Officer. In addition, our Board of Directors has determined that each member of the Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee meets the applicable Nasdaq and SEC rules and regulations regarding “independence” and that each member is free of any relationship that would interfere with his or her individual exercise of independent judgment with regard to the Company. In making these independence determinations, our Board of Directors considered the current and prior relationships that each non-employee director has with our Company and all other facts and circumstances our Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

Board of Directors Leadership Structure

The positions of Chair of the Board of Directors and Chief Executive Officer are currently separated. Dr. MacQuitty will continue serving as our Chair of the Board of Directors through the date of the Annual Meeting, and thereafter Ms. Eastham will, if re-elected, serve as our Chair of our Board of Directors. Mr. West serves as our Chief Executive Officer. We believe separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing our Chair to lead our Board of Directors in its fundamental role of providing advice to and oversight of other members of management. Our Board of Directors recognizes the time, effort, and energy that the Chief Executive Officer must devote to his position in the current business environment, particularly as our Board of Directors’ oversight responsibilities continue to grow.

Although our bylaws and Corporate Governance Guidelines do not require that we separate the Chair and Chief Executive Officer positions, our Board of Directors believes that having separate positions is the appropriate leadership structure for us at this time. Our Board of Directors recognizes that, depending on the circumstances, other leadership models, such as combining the role of Chair with the role of Chief Executive Officer, might be appropriate. Accordingly, our Board of Directors may periodically review its leadership structure. Our Board of Directors believes its administration of its risk oversight function has not affected its leadership structure.

Our Corporate Governance Guidelines provide that in the event that the Chair is not an independent director, our Board of Directors may designate one of the independent directors to serve as the Lead Independent Director. Specific roles and responsibilities of the Lead Independent Director, which are detailed in our Corporate Governance Guidelines, include:

•

presiding at all meetings of the Board of Directors at which the Chair is not present, including executive sessions of the independent directors;

•

acting as liaison between the independent directors and the Chief Executive Officer and Chair;

•

presiding over meetings of the independent directors;

•

consulting with the Chair in planning and setting schedules and agendas for meetings of the Board of Directors to be held during the year; and

•

performing such other functions as the Board of Directors may delegate.

As discussed above, except for our Chief Executive Officer, our Board of Directors is comprised of independent directors. The active involvement of these independent directors provides balance on the Board of Directors and promotes strong, independent oversight of our management and affairs.

Role of the Board of Directors in Risk Oversight

Our Board of Directors believes that risk management is an important part of establishing, updating, and executing on our business strategy. Our Board of Directors, as a whole and at the committee level, has oversight responsibility relating to risks that could affect the corporate strategy, business objectives, compliance, operations, and the financial condition and performance of the Company. Our Board of Directors focuses its oversight on the most significant risks facing the Company and on its processes to identify, prioritize, assess, manage, and mitigate those risks. Our Board of Directors and its committees receive regular reports from members of the Company’s senior management on areas of material risk to the Company, including strategic, operational, financial, cybersecurity, legal, and regulatory risks, as well as risks related to the ongoing COVID-19 pandemic. While our Board of Directors has an oversight role, management is principally tasked with direct responsibility for management and assessment of risks and the implementation of processes and controls to mitigate their effects on the Company.

The Audit Committee is responsible for overseeing our financial reporting process on behalf of our Board of Directors and reviewing with management and our auditors, as appropriate, our major financial risk exposures as well as risks relating to data privacy, technology, and information security, including cybersecurity and back-up of information systems, and the steps taken by management to monitor and control these exposures. The Compensation Committee is responsible for overseeing our practices and policies of employee compensation as they relate to risk management and risk-taking incentives to determine whether such compensation policies and practices are reasonably likely to have a material adverse effect on the Company. The Nominating and Corporate Governance Committee oversees the management of risks associated with our overall compliance and corporate governance practices and the independence and composition of our Board of Directors. These committees provide regular reports to the full Board of Directors.

With respect to cybersecurity, the Audit Committee monitors our cybersecurity risk profile, receives periodic updates from management on all matters related to cybersecurity, and reports out to the full Board of Directors, and assists the Board of Directors in providing oversight and assessment relating to the identification and evaluation of operational, regulatory, compliance, and external cybersecurity risks inherent to our business, and other risks related to data privacy and information technology. The Audit Committee reviews our cybersecurity management processes and infrastructure and discusses and evaluates any risks identified by such processes or otherwise, including cybersecurity risks and other risks related to information technology, and any mitigation activities put in place in response to such risks.

We have based our cybersecurity assessment approach on the National Institute of Standards and Technology Cybersecurity Framework and are implementing methodologies that are consistent with that framework, such as asset management, leading protection and detection technologies, continual monitoring, employee training and business continuity plans. We arrange for independent security assessments to keep us up to date on new security gaps and measures we can implement. Additionally, we conduct random phishing and penetration tests to assess our defenses as well as our employees’ awareness of cybersecurity risks.

Expectations of Board Members

Director Orientation and Continuing Education

Directors are expected to stay abreast of our strategic plans, key policies and practices, and industry trends. Our General Counsel and Chief Financial Officer are responsible for assuring the orientation of new directors, and for periodically providing materials or briefing sessions for all directors on subjects that would assist them in exercising their duties. The Board of Directors has approved a policy that provides for reimbursement of continuing education expenses for each director. In addition, the Company provides opportunities for directors to visit Company facilities in order to provide greater understanding of the Company’s business and operations.

Service on Other Boards

The Board of Directors recognizes that a director’s ability to fulfill his or her responsibilities as a member of the Board of Directors can be impaired if he or she serves on a large number of other boards or board committees. To that end, our Corporate Governance Guidelines provide that, unless approved by the Board of Directors, non-employee directors should generally serve on no more than four other public company boards and non-employee directors who are executive officers of other public companies should generally serve on no more than one other public company board. In selecting nominees for election (or for re-election, in the case of incumbent directors whose terms of office are set to expire), the Board of Directors takes into account the other demands on the time of a candidate.

Director Evaluation and Board, Committee, and Individual Director Self-Assessments

In order to help ensure that the current and future business needs of the Company are being served, the Nominating and Corporate Governance Committee facilitates annual Board and committee self-assessments, including director assessments of the performance of the Board of Directors as a whole, and director assessments of the performance of each committee on which he or she serves, and facilitates discussion among directors regarding the assessment results and any potential changes to the Company’s governance process indicated by the assessments.

Meetings of the Board of Directors

The Board of Directors met seven times during 2021. Each director attended 75% or more of the aggregate number of meetings of the Board of Directors and of the committees on which he or she served, held during the portion of 2021 for which he or she was a director or committee member.

Effective as of the Annual Meeting of Stockholders in 2022, Mr. Bowman will join the Compensation Committee and serve as Chair. Our Board of Directors has determined that each of Drs.

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 Chair of the Compensation Committee, in consultation with the Chief Executive Officer and Aon’s Human Capital Solutions practice, a division of Aon plc (“Aon”), the Compensation Committee’s independent 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 of our books, records, facilities, and personnel. In addition, under the charter, the Compensation Committee has the authority to obtain, at our expense, 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 Compensation 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.

During the past fiscal year, after taking into consideration the six factors prescribed by the SEC and Nasdaq described above, the Compensation Committee engaged Aon as a compensation consultant. The Compensation Committee requested that Aon review industry-wide compensation practices and trends to assess the competitiveness of our executive and non-employee director compensation programs.

As part of its engagement, Aon was requested by the Compensation Committee to develop a comparative group of companies and to perform analyses of competitive performance and compensation levels for that group, to evaluate our equity compensation policies and practices, examine executive severance, provide information on governance and market trends in addition to performing and independent review of compensation for our non-employee directors As needed, Aon provided various policy reviews and recommendations as input into the Compensation Committee’s discussions and decisions. Aon met with the Compensation Committee in executive session, as requested, in support of the Compensation Committee’s responsibilities. The Compensation Committee following its discussions and deliberations, makes recommendations as needed to the Board of Directors to approve certain matters.

Compensation Committee Interlocks and Insider Participation

None of the members of the Compensation Committee is currently or has been at any time one of our officers or employees. None of our executive officers currently serves, or has served during the last year, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our Board of Directors or Compensation Committee.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee currently consists of Ms. Eastham and Drs. Colowick and Myers. The Chair of our Nominating and Corporate Governance Committee is Ms. Eastham. Our Board of Directors has determined that each of Ms. Eastham and Drs. Colowick and Myers are independent under the applicable Nasdaq listing standards. The functions of this committee include:

•

identifying and evaluating candidates, including the nomination of incumbent directors for reelection and nominees recommended by stockholders, to serve on our Board of Directors;

•

considering and making recommendations to our Board of Directors regarding the composition and chairs of the committees of our Board of Directors;

•

developing and making recommendations to our Board of Directors regarding corporate governance guidelines and matters; and

•

overseeing periodic evaluations of the Board of Directors’ performance, including committees of the Board of Directors.

The Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements and having the highest personal integrity and ethics. The Nominating and Corporate Governance 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; demonstrating excellence in his or her field; having the ability to exercise sound business judgment; having experience as a board member or executive officer of another publicly held company; having a diverse personal background, perspective, and experience; and having the commitment to rigorously represent the long-term interests of our stockholders. However, the Nominating and Corporate Governance 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 of Directors, the operating requirements of Personalis, and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity, age, skills, and such other factors as it deems appropriate, given the current needs of the Board of Directors and Personalis, to maintain a balance of knowledge, experience, and capability. The Nominating and Corporate Governance Committee believes that it is important that directors represent diverse viewpoints. To this end, the Nominating and Corporate Governance Committee assesses diversity of gender, race and national original, as well as other self-identified diversity characteristics, in connection with the annual nomination process and in new director searches.

In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews these directors’ overall service to Personalis 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. In the case of new director candidates, the Nominating and Corporate Governance Committee uses its resources to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance 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 and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board of Directors. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board of Directors by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance 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 and Corporate Governance Committee to become nominees for election to the Board of Directors may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 1330 O’Brien Drive, Menlo Park, California 94025. Submissions must include, among other items required by our bylaws, the name, age, business address and residence address of the proposed nominee; the principal occupation or employment of such nominee; the class and number of shares of each class of capital stock of Personalis that are owned of record and beneficially by the proposed nominee; the date or dates on which such shares were acquired and the investment intent of such acquisition; a statement whether the proposed nominee, if elected, intends to tender, promptly following such person’s failure to receive the required vote for election or re-election at the next meeting at which such person would face election or re-election, an irrevocable resignation effective upon acceptance of such resignation by the Board of Directors; and such other information concerning such nominee as would be required to be disclosed in a proxy statement soliciting proxies for the election of such nominee as a director in an election contest (even if an election contest is not involved), or that is otherwise required to be disclosed pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder (including such person’s written consent to being named as a nominee and to serving as a director if elected).

Stockholder Communications With the Board of Directors

Our Board of Directors believes that stockholders should have an opportunity to communicate with the Board of Directors, and efforts have been made to ensure that the views of stockholders are heard by the Board of Directors or individual directors, as applicable, and that appropriate responses are provided to stockholders in a timely manner. We believe that our responsiveness to stockholder communications to the Board of Directors has been excellent. Stockholders wishing to communicate with the Board of Directors or an individual director may send a written communication to the Board of Directors or such director c/o Personalis, Inc., 1330 O’Brien Drive, Menlo Park, California 94025, Attn: Corporate Secretary. The Corporate Secretary will review each communication. The Corporate Secretary will forward such communication to the Board of Directors or to any individual director to whom the communication is addressed unless the communication contains advertisements or solicitations or is unduly hostile, threatening, or similarly inappropriate, in which case the Corporate Secretary shall discard the communication.

Code of Business Conduct and Ethics

We have adopted a Code of Business Conduct and Ethics that applies to all of our employees, officers, and directors, including those officers responsible for financial reporting. The full text of our Code of Business Conduct and Ethics is posted on the Investors section of our website at www.personalis.com. Annually, the Audit Committee of our Board of Directors reviews and assesses the adequacy of our Code of Business Conduct and Ethics and recommends any proposed changes to our Board of Directors for approval. We intend to disclose future amendments to certain provisions of our Code of Business Conduct and Ethics, or waivers of such provisions, applicable to any principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and our directors, on our website identified above.

Corporate Governance Guidelines

As part of our Board of Directors’ commitment to enhancing stockholder value over the long term, our Board of Directors has adopted a set of Corporate Governance Guidelines to provide the framework for

the governance of the Company and to assist our Board of Directors in the exercise of its responsibilities. Our Corporate Governance Guidelines cover, among other topics, board composition and structure, board membership criteria, director independence, board and board committee assessments, committees of the Board of Directors, board access to management and outside advisors, and director orientation and education. The Corporate Governance Guidelines, as well as the charters for each committee of the Board of Directors, may be viewed on the Investors section of our website at www.personalis.com.

Sustainability and Corporate Responsibility

Environment

We are committed to conducting business in a way that considers our environment and the Earth’s changing climate, and that is also consistent with providing a high state of wellness and success for our employees and other stakeholders. To date, we have incorporated environmentally sustainable practices into certain of our facilities and operations, and we plan to invest in more of these practices as we continue to grow. Our approach is to foster growth and longevity and to create long-term value by considering every dimension of how we operate – ethical, economic, and environmental. Through this plan, we strive to contribute to bettering our world by making a positive impact on people and the planet.

Our People

We recognize that our employees are both our most valuable asset and our most important investment. The success of our organization is reliant upon each individual’s significant contribution to our corporate culture and goals in line with our core company values of:

•

Integrity

•

Respect

•

Teamwork and collaboration

•

Commitment to scientific excellence

•

Dedication to discovery and innovation

•

Passion

We recognize the importance of our efforts in facilitating the development of safer, more effective targeted cancer therapies and immunotherapies. We regularly seek to reinforce to our employees the connection between our mission to transform the development of next-generation cancer therapies by providing more comprehensive molecular data about each patient’s tumor and its potential benefits to society.

At a foundational level, employees receive training related to workplace safety and emergency preparedness, awareness and expectations of inclusion and diversity, required data protection, and other regulatory matters. We offer competitive total rewards programs, ongoing training and development, and a commitment to the safety and health of our employees. We also practice a commitment to diversity by including broader outreach and sourcing for candidates for new roles as well as education and a visible commitment to diversity and inclusion internally. For example, we established a Diversity Committee in 2020 with its mission to promote a sense of belonging for all our employees.

An engaged workforce with skills specific to our needs is critical for our successful growth in a competitive market and sector. We regularly benchmark our compensation and benefits by geography,

industry (life sciences), and by role to ensure we maintain our status as an employer of choice in these areas. Our turnover rates over the last three years have been consistent with such benchmarks. Reports of our position relative to the benchmarks are reported to management and the Compensation Committee of our Board of Directors on a periodic basis.

Prohibitions on Hedging, Pledging and Short-Term Speculative Transactions

Our Insider Trading Policy, adopted in May 2019 and amended in November 2020, prohibits our employees, directors, or designated consultants (or any other person subject to the policy) who is aware of material nonpublic information relating to Personalis from:

•

engaging in short sales, transactions in put options, call options or other derivative securities on an exchange or in any other organized market, or in any other inherently speculative transactions with respect to Personalis’ common stock;

•

engaging in transactions that use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds; or

•

holding Personalis’ common stock in a margin account or otherwise pledging Personalis’ common stock as collateral for a loan.

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has selected Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2022 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. Deloitte & Touche LLP has audited our financial statements since 2018. Representatives of Deloitte & Touche LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm. However, the Audit Committee of the Board of Directors is submitting the selection of Deloitte & Touche LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of our company and our stockholders.

Vote Required

The affirmative vote of the holders of a majority of the shares present online or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to approve this Proposal 2.

The Board of Directors Recommends

a Vote “For” Proposal 2.

Principal Accountant Fees and Services

The following table represents aggregate fees billed to Personalis for the years ended December 31, 2021 and 2020, by Deloitte & Touche LLP, our independent registered public accounting firm.


	Year Ended December 31,
	2021		2020
	(in thousands)
Audit Fees ⁽¹⁾	$	1,546	$	969
Audit-Related Fees		—		—
Tax Fees ⁽²⁾		18		36
All Other Fees		—		—

Total Fees	$	1,564	$	1,005

(1)

Audit Fees includes fees for Deloitte & Touche LLP’s audit of our annual financial statements and internal control over financial reporting, quarterly review of financial statements, and services that are normally provided by the independent registered public accounting firm in connection with regulatory filings for those fiscal years. This category also includes fees for comfort letters and consents issued in connection with SEC filings. Fiscal 2021 fees were higher than fiscal 2020 fees because fiscal 2021 was the first year in which we were required to obtain auditor attestation on our internal controls over financial reporting.

(2)	Tax Fees includes fees for tax advice, tax planning, and transfer pricing in connection with our expansion into China.

All fees incurred were pre-approved by our Audit Committee.

Pre-Approval Procedures

The Audit Committee has procedures in place for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, Deloitte & Touche LLP. The Audit Committee 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.

PROPOSAL 3

APPROVAL, ON A NON-BINDING, ADVISORY BASIS, OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), and Section 14A of the Exchange Act, our stockholders are entitled to vote to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with SEC rules.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies, and practices described in this proxy statement. We have designed our executive compensation program to attract, motivate, reward, and retain the senior management talent required to achieve our corporate objectives and to increase long-term stockholder value. The compensation of our named executive officers subject to the vote is disclosed in the Executive Compensation discussion below, the compensation tables, and the related narrative disclosure contained in this proxy statement.

Accordingly, the Board is asking the stockholders to indicate their support for the compensation of our named executive

officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Executive Compensation discussion below, compensation tables and narrative discussion, is hereby APPROVED.”

This vote is advisory; it is not binding on the Board. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements. Advisory approval of this proposal requires the vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the annual meeting.

Vote Required

Approval of this proposal requires the vote of the holders of a majority of the shares present online or represented by proxy and entitled to vote on the matter at the Annual Meeting. Abstentions will be counted toward a quorum for Proposal 3 and will have the same effect as “Against” votes. Broker non-votes will have no effect.

The Board of Directors Recommends

a Vote “For” Proposal 3.

PROPOSAL 4

INDICATION, ON A NON-BINDING, ADVISORY BASIS, OF THE PREFERRED FREQUENCY OF HOLDING FUTURE ADVISORY VOTES ON THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

The Dodd-Frank Wall Street Reform and Consumer Protection Act, and Section 14A of the Exchange Act, enable the Company’s stockholders, at least once every six years, to indicate their preference regarding how frequently the Company should solicit a non-binding advisory vote on the compensation of the Company’s named executive officers as disclosed in the Company’s proxy statement. Accordingly, the Company is asking its stockholders to indicate whether they would prefer an advisory vote every one, two, or three years. Alternatively, stockholders may abstain from casting a vote. For the reasons described below, the Board recommends that the stockholders select a frequency of three years.

Our Board of Directors has determined that holding an advisory vote on executive compensation every third year is the most appropriate policy for us at this time as it aligns our interest in stockholder input with our long-term value creation goals. In addition, a vote every third year will allow for more a comprehensive and thorough plan analysis and provide us with the time to thoughtfully respond to stockholders’ sentiments and implement any necessary changes. As such, our Board of Directors recommends that stockholders vote for future advisory votes on executive compensation to occur every third year. Our Board of Directors considered that an advisory vote every three years on executive compensation will allow our stockholders to provide us with their direct input on our compensation philosophy, policies, and practices. However, stockholders should note that because the advisory vote on executive compensation occurs well into the compensation year, and because the different elements of our executive compensation program are designed to operate as part of an integrated program, it may not be appropriate or feasible to modify our executive compensation program in consideration of any one advisory vote on executive compensation by the time of the following year’s annual meeting of stockholders.

We understand that our stockholders may have different views as to what is the best approach for us, and we look forward to hearing from our stockholders on this proposal.

Accordingly, our Board of Directors is asking the stockholders to indicate their preferred voting frequency by voting for every year, every two years, or every three years.

While our Board of Directors believes that its recommendation is appropriate at this time, the stockholders are not voting to approve or disapprove that recommendation, but are instead asked to indicate their preferences, on an advisory basis, as to whether the non-binding advisory vote on the approval of our executive officer compensation practices should be held every year, every two years, or every three years. In accordance with our bylaws, a voting frequency will only be deemed selected by our stockholders if it receives the votes of the holders of a majority of shares present virtually or represented by proxy and entitled to vote on this matter at the Annual Meeting. If you “Abstain” from voting, it will have the same effect as a vote “Against” each of the proposed voting frequencies. However, if none of the proposed voting frequencies receives the votes of the holders of a majority of shares present virtually or represented by proxy and entitled to vote on the matter at the Annual Meeting, we will consider the frequency receiving the highest number of affirmative votes from the holders of shares present virtually or represented by proxy and entitled to vote at the Annual Meeting to be the frequency preferred by our stockholders. In either case, broker non-votes will have no effect.

Our Board of Directors and the Compensation Committee value the opinions of our stockholders in this matter, and, to the extent there is any significant vote in favor of one frequency over the other options, our Board will consider the stockholders’ concerns and evaluate any appropriate next steps. However,

because this vote is advisory and, therefore, not binding on us or our Board of Directors, our Board may decide that it is in the best interests of our stockholders that we hold an advisory vote on executive compensation more or less frequently than the option preferred by our stockholders. The vote will not be construed to create or imply any change or addition to our fiduciary duties or those of our Board.

Vote Required

Approval of this proposal requires “For” votes of the holders of a majority of the shares present online or represented by proxy and entitled to vote on the matter at the Annual Meeting. Abstentions will be counted toward a quorum for Proposal 4 and will have the same effect as “Against” votes. Broker non-votes will have no effect.

The Board of Directors Recommends

a Vote of “3 Years” for Proposal 4.

Narrative to Summary Compensation Table

The overall objectives of our executive compensation program are based on the following key principles:

•

attracting, retaining, and motivating top quality executives;

•

providing incentives that reward the achievement of performance goals; and

•

aligning the interests of executives with those of stockholders.

The three principal components of our executive compensation program for our named executive officers in 2021 were base salary, annual bonus, and equity compensation. We do not have any formal policies for allocating compensation among these components. Instead, our Compensation Committee uses its judgment to establish a total compensation program for each named executive officer that is a mix of current, short-term, and long-term incentive compensation, and cash and non-cash compensation, that it believes appropriate to achieve the goals of our executive compensation program and our corporate objectives. In line with our pay-for-performance philosophy, we structured a significant portion of our named executive officers’ 2021 compensation to be variable, at risk, and tied directly to our measurable performance in the form of performance-based bonuses and equity incentives.

Our Compensation Committee reviews compensation annually for our executives. In setting executive base salaries and bonuses and granting equity incentive awards, the Compensation Committee considers compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to our company.

The operation of our Compensation Committee is described in more detail above in the section titled, “Compensation Committee Processes and Procedures.”

The Compensation Committee uses the services of an independent compensation consultant who is retained by, and reports directly to, the Compensation Committee to provide the Compensation Committee with an additional external perspective with respect to its evaluation of relevant market and industry practices. Since 2019, the Compensation Committee has retained Aon to assist the Compensation Committee in establishing overall compensation levels. Aon conducted analyses and provided advice on, among other things, our equity compensation policies and practices, executive compensation and severance, and compensation for our non-employee directors.

The peer group was recommended by Aon and approved by the Compensation Committee in July 2021 based on the following parameters:


Peer Group Criteria

• Public U.S.-based medical device, diagnostics, and life science tools companies with revenue between $50 million and $250 million;

• Companies with market cap generally between $300 million and $3.0 billion and between 100 and 750 employees; and

• U.S.-based companies with a focus on companies headquartered in the San Francisco Bay Area in California and other biotech “hub” locations

The peer group of companies used by the Compensation Committee in making 2021 compensation decisions was comprised of the following companies:


Peer Companies:
Antares Pharma
Axonics Modulation Technology
CareDx
Castle Biosciences
ChromaDex
Codexis
Fluidigm
GenMark Diagnostics
Intersect ENT
NanoString Technologies
Oxford Immunotec Global
Quanterix
Retrophin
SI-BONE
Tactile Systems Technology
Twist Bioscience
Veracyte

Base Salary

Our Compensation Committee recognizes the importance of base salary as an element of compensation that helps to attract and retain our executive officers. We provide base salary as a fixed source of cash compensation to recognize each named executive officer’s day-to-day responsibilities, which is designed to provide an appropriate and competitive base level of current cash income for the named executive officers. The 2021 annual base salaries of Messrs. West and Tachibana and Dr. Chen were approved by the Board of Directors in April 2021 to become effective April 1, 2021.

The 2020 and 2021 base salaries were as follows:


Named Executive Officer	2020 Base Salary		2021 Base Salary		% Change
John West	$	550,000	$	600,000		9	%
Aaron Tachibana	$	425,000	$	450,000		6	%
Richard Chen, M.D., M.S.	$	450,000	$	475,000		6	%

Annual Bonus Plan

Our executive officers are eligible to receive performance-based cash bonuses, which are designed to provide appropriate incentives to our executives to achieve pre-defined performance goals and to reward our executives for individual achievement toward these goals. The performance-based bonus each 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 and is paid annually. Annually, the Compensation Committee reviews the Company’s performance and determines the actual bonus payout to be awarded to each of our eligible executive officers.

For 2021, our named executive officers were eligible to earn annual cash bonuses based on the Compensation Committee’s determination of achievement of certain performance objectives recommended by it and approved by our Board of Directors.

Variable cash incentives offered to these named executive officers during 2021 afforded the opportunity for our Chief Executive Officer to earn up to 80% of his base salary and our other named executive officers to earn up to 40% of their base salary based on the achievement of certain financial, operational, and research and development metrics, each with separate, varied weightings. These performance goals for 2021 consisted of total GAAP-based revenue and GAAP-based revenue excluding revenue from the U.S. Department of Veterans Affairs Million Veteran Program recognized in 2021 (weighted at 30% and 40%, respectively), gross margin, (weighted at 10%), external collaborative studies (weighted at 10%), and certain operational goals related to anticipated future regulatory approvals and reimbursement (weighted at 10%). Generally, threshold achievement of the applicable revenue goal resulted in payout with respect to that goal of 90%, up to a maximum of 125% payout for maximum achievement, and 100% payout at target achievement; threshold achievement of the applicable non-revenue goal resulted in payout with respect to that goal of 100% at target achievement. Typically, our Chief Executive Officer provides an evaluation of the Company’s overall performance against goals and makes a recommendation for the funding of the plan and the individual awards. Based on the Compensation Committee’s assessment, the final awards are determined, making adjustments up or down for the actual incentive cash paid for each of these named executive officers, to reflect the individual’s contributions to our corporate goals. During 2021, 128% of our goals were achieved, resulting in our Chief Executive Officer achieving 102.4% of his target variable cash opportunity.. The objectives with respect to the 2021 incentive bonuses were aggressive, but attainable. Consistent with prior years, we established these 2021 objectives to be stretch goals that are intentionally challenging such that performance at target would require significant achievements across multiple performance criteria.

The 2021 annual bonuses were as follows:


Named Executive Officer	2021 Base Salary		2021 Bonus Target			2021 Corporate Goal Achievement			2021 Bonus Achievement
John West	$	600,000		80	%		128	%		102.4	%
Aaron Tachibana	$	450,000		40	%		128	%		51.2	%⁽¹⁾
Richard Chen, M.D., M.S.	$	475,000		40	%		128	%		51.2	%⁽¹⁾

(1)	The amount of bonus is not calculable through the latest practicable date. We expect the bonuses earned for the year ended 2021 to be determined on or about April 26, 2022.

Equity Compensation

In establishing the equity grant ranges, the Compensation Committee considered the market trends for annual equity grants, the mix of equity vehicles with the market assessment as well as the retention holdings for the named executive officers. The annual grant ranges established were based on annual equity value consistent with our total compensation approach, our pay for performance culture as well as the retention value of the outstanding awards. Our Chief Executive Officer used this data, as one input into making recommendations to the Compensation Committee for annual equity grants the value of which would be delivered in the form of approximately 50% stock options and 50% restricted stock units. The Compensation Committee used a mix of equity instruments to manage risk and retention while motivating leaders to deliver strong operating performance to improve the share price for stockholders. We believe that our ability to grant equity-based awards is a valuable and necessary compensation tool that aligns the long-term financial interests of our executive officers with the financial interests of our stockholders. In addition, we believe that our ability to grant equity-based awards helps us to attract, retain, and motivate executive officers, and encourages them to devote their best efforts to our business and financial success. Vesting of equity awards is generally tied to continuous service with us and serves as an additional retention measure. Our executive officers generally are awarded an initial new hire grant upon commencement of employment, as well as annual grants.

Each of our named executive officers currently holds stock options under our 2019 Equity Incentive Plan (the “2019 Plan”), and our 2011 Equity Incentive Plan (the “2011 Plan”), that were granted subject to the general terms of the applicable plan and the applicable forms of stock option agreement thereunder. The specific vesting terms of each named executive officer’s stock options are described below under “—Outstanding Equity Awards at December 31, 2021.” For additional information about our equity compensation plans, please see the section titled “—Equity Compensation Plans” below.

We currently grant all equity awards pursuant to the 2019 Plan or our 2020 Inducement Plan (the “2020 Plan”). All options are granted with a per share exercise price equal to no less than the fair market value of a share of our common stock on the date of the grant, and generally vest 25% after one year from the vesting commencement date and on a monthly basis thereafter over 36 months for the initial new hire grant and on a monthly basis over 48 months for annual grants, subject to continued service with us through each vesting date. All options have a maximum term of up to 10 years from the date of grant, subject to earlier expiration following the cessation of an executive officer’s continuous service with us. Options generally remain exercisable for 90 days following an executive officer’s termination, except in the event of a termination for cause or due to disability or death. Restricted stock units generally vest on an annual basis over four years for the initial new hire grant and on a semi-annual basis over four years for annual grants, subject to the continued service with us through each vesting date. Option and restricted stock unit vesting is subject to acceleration as described below under “—Potential Payments upon Termination or Change in Control” and “—Equity Compensation Plans.”

In May 2021, upon recommendation from the Compensation Committee, the Board of Directors granted to each of Mr. West, Mr. Tachibana and Dr. Chen (i) a stock option to purchase 107,500 shares, 40,000 shares, and 45,000 shares of our common stock, respectively, under the 2019 Plan, which vest in 48 equal monthly installments, subject to each executive’s continued service to us on each applicable vesting date and (ii) a restricted stock unit award of 53,750 shares, 20,000 shares, and 20,000 shares, respectively, under the 2019 Plan, which vest in 8 equal semiannual installments, subject to each executive’s continued service to us on each applicable vesting date. In May 2021, upon recommendation from the Compensation Committee, the Board of Directors additionally granted Mr. West a stock option to purchase 110,000 shares under the 2019 Plan, which vests in 12 equal monthly installments commencing after March 17, 2023, subject to Mr. West’s continued service to us on each applicable vesting date. In July 2021, in connection with their promotions to Senior Vice President, the Compensation Committee granted to each of Mr. Tachibana and Dr. Chen (i) a stock option to purchase 12,500 shares under the 2019 Plan, which vest in 48 equal monthly installments, subject to each executive’s service to us on each applicable vesting date and (ii) a restricted stock unit award of 10,000 shares, under the 2019 Plan, which vest in 8 equal semiannual installments, subject to each executive’s continued service to us on each applicable vesting date. In December 2021, based upon the recommendation of Mr. West for retention of certain key employees, the Compensation Committee granted to each of Mr. Tachibana and Dr. Chen a restricted stock unit award of 80,000 shares, under the 2019 Plan, which vest in 6 equal semiannual installments, subject to each executive’s continued service to us on each applicable vesting date.

Pay for Performance/At-Risk Pay

Our executive compensation program is designed to reward achievement of the specific strategic goals that we believe will advance our business strategy and create long-term value for our stockholders. Consistent with our goal of attracting, motivating, and retaining a high-caliber executive team, our executive compensation program is designed to pay for performance. We utilize compensation elements that meaningfully align our named executive officers’ interests with those of our stockholders to create long-term value. As such, a significant portion of our Chief Executive Officer’s and other named executive officers’ compensation is “at-risk”, performance-based compensation, in the form of long-term equity awards and annual cash incentives that are only earned if we achieve measurable corporate metrics.

Employment Terms

We have entered into employment agreements or offer letters with each of our named executive officers. Descriptions of such arrangements with our named executive officers are included under the caption “ —Employment Arrangements” below.

Compensation Recoupment and Forfeiture Policy

The Board of Directors adopted a Compensation Recoupment and Forfeiture Policy, also known as a “clawback” policy. The policy applies to incentive-based cash compensation and incentive-based equity awards (the “Covered Amounts”) granted to or received by our current and former Section 16 officers. Under the policy, any Covered Amounts granted or received by a Section 16 officer after the date of the clawback policy’s adoption that are predicated upon our achievement of certain financial results will, in the discretion of the Board of Directors or the Compensation Committee, be subject to recoupment or forfeiture if: (1) the Company’s quarterly or annual financial statements are adjusted to correct one or more errors having a material impact on the Company’s financial statements; and (2) the Board of Directors or the Compensation Committee determine that the Section 16 officer engaged in Misconduct (as defined in the policy) that materially contributed to the need for such restatement. The amounts subject to recoupment are any Covered Amounts that are in excess of any compensation that would have been earned by the Section 16 officer based on the restated financial results. In addition to the foregoing, our Chief Executive Officer and Chief Financial Officer are subject to the compensation recovery provisions of Section 304 of the Sarbanes-Oxley Act.

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 earned during his or her term of service, including unpaid salary and unused vacation.

We have entered into an agreement with each of our named executive officers with respect to potential payments and benefits due upon a termination of employment or change in control. In February 2022, the Compensation Committee approved the amendment and restatement of the terms of executive severance agreements for Messrs. West and Tachibana and Dr. Chen, each dated February 23, 2022 (collectively, the “A&R Executive Severance Agreements”).

John West

Pursuant to his employment agreement (as amended) with us, Mr. West is entitled to accelerated vesting for each of his then-outstanding unvested equity awards that would have vested within the next

12 months if a “change in control” (as defined in the 2019 Plan or the 2011 Plan, as applicable) occurs during his employment with us.

The amended provisions of the A&R Executive Severance Agreement with Mr. West provide that, among other things:

•

In the event that we terminate Mr. West’s employment without “cause” (and other than as a result of his death or disability) or he resigns for “good reason” (each, a “separation from service”, as further defined in the West Severance Agreement), the period to receive payment of COBRA health insurance premiums will be shortened to the earlier of (i) 12 months or (ii) the date upon which Mr. West obtains coverage under a subsequent employer’s medical plan.

•

In the event of a separation from service within 12 months after the effective date of “change in control” (as defined in the West Separation Agreement), the vesting of each of Mr. West’s then-outstanding unvested equity compensation awards shall accelerate as to all of then-unvested shares subject to each such award, or, in the case of any other separation from service, the vesting of each of Mr. West’s then-outstanding unvested equity compensation awards shall accelerate as to the number of the then-unvested shares subject to each such award that would have become vested within the first 24 months following such separation from service, subject to certain conditions.

Aaron Tachibana

The amended provisions of the A&R Executive Severance Agreement with Mr. Tachibana provide that, among other things:

•

In the event that we terminate Mr. Tachibana’s employment without “cause” (and other than as a result of his death or disability) or he resigns for “good reason” (each, a “separation from service”, as further defined in the Officer Severance Agreements), the period to receive payment of COBRA health insurance premiums will be shortened to the earlier of (i) 12 months for Mr. Tachibana or (ii) the date upon which the executive obtains coverage under a subsequent employer’s medical plan.

•

In the event that there is a separation from service that is not within 12 months after a “change in control” (as defined in the Officer Severance Agreements), the executive will be entitled to 6 months of his then current base salary, subject to certain conditions.

Richard Chen, M.D., M.S.

The amended provisions of the A&R Executive Severance Agreement with Dr. Chen provide that, among other things:

•

In the event that we terminate Dr. Chen’s employment without “cause” (and other than as a result of his death or disability) or he resigns for “good reason” (each, a “separation from service”, as further defined in the Officer Severance Agreements), the period to receive payment of COBRA health insurance premiums will be shortened to the earlier of (i) 9 months for Dr. Chen or (ii) the date upon which the executive obtains coverage under a subsequent employer’s medical plan.

•

Under the A&R Executive Severance Agreements for each of Messrs. West and Tachibana and Dr. Chen, the following definitions are used:

•

“Cause” generally means (1) the executive’s gross negligence or knowing and willful action which is or is likely to be materially injurious to us; (2) any intentional act by the executive in connection

with the executive’s responsibilities as an employee constituting fraud or a felony crime; (3) the executive’s consistent failure to report for work or perform the executive’s duties as directed by the Board of Directors; (4) persistent or repeated material breach of the A&R Executive Severance Agreement or any agreement between the executive and us; (5) the executive becoming disqualified from holding office through the executive’s own act or omission; (6) an unauthorized use or disclosure by the executive of our confidential information or trade secrets, which use or disclosure causes material harm to us; or (7) a material failure by the executive to comply with our written policies or rules which is or is likely to be materially injurious to us; and

•

“Good reason” generally means (1) a reduction of at least 10% of the executive’s base salary (excluding such a reduction made in connection with an across-the-board salary reduction affecting all members of management); (2) for Mr. West, a requirement that he report to a corporate officer rather than directly to the Board of Directors, or a material reduction in his duties, responsibilities and/or authority, provided, however, that our acquisition in a “change in control” (as defined in the West Separation Agreement) and subsequent conversion to a division or unit of the acquiring company will not by itself result in any such “material reduction,” (3) for Mr. Tachibana or Dr. Chen, a material reduction in the executive’s duties, responsibilities and/or authority, provided, however, that a change in job position (including a change in title) after or in connection with a “change in control” (as defined in the Officer Severance Agreements) shall not be deemed a “material reduction” in and of itself unless the executive’s new duties are materially reduced from the executive’s prior duties; (4) a relocation of the executive’s principal place of employment to a place that increases the executive’s one-way commute by more than 50 miles as compared to the executive’s then-current principal place of employment immediately prior to such relocation (excluding such a relocation that is within 20 miles of Palo Alto, California); or (5) a material breach by us of the A&R Executive Severance Agreement, except that, in order to resign for good reason, the executive must provide written notice to the Board of Directors within 30 days after the first occurrence of the event giving rise to good reason setting forth the basis for the executive’s resignation, allow us at least 30 days from receipt of such written notice to cure such event, and if such event is not reasonably cured within such period, the executive must resign from all positions the executive then holds with us not later than 30 days after the expiration of the cure period or the date of notification to the executive that we will not so cure.

Other Compensation and Benefits

All of our current named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision, life, disability, and accidental death and dismemberment insurance plans, in each case on the same basis as all of our other employees. We pay the premiums for the life, disability, and accidental death and dismemberment insurance for all of our employees, including our named executive officers.

Our named executive officers did not participate in, or earn any benefits under, any nonqualified deferred compensation plan sponsored by us during the fiscal year ended December 31, 2021. Our Board of Directors may elect to provide our officers and other employees with nonqualified deferred compensation benefits in the future if it determines that doing so is in our best interests.

Our current named executive officers participated in our 401(k) plan and, during fiscal 2021, each received a matching contribution in the amount of $1,500.

401(k) Plan

We maintain a 401(k) plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax-advantaged basis. Eligible employees are able to defer eligible compensation up to certain limits under the Internal Revenue Code of 1986, as amended (the “Code”), which are updated

annually. Our named executive officers are eligible to participate in the 401(k) plan. We have the ability to make matching and discretionary contributions to the 401(k) plan. Beginning in 2020, we began making matching contributions to the 401(k) plan up to $1,000 per participating employee, and increased such contributions to $1,500 in 2021. The 401(k) plan is intended to be qualified under Section 401(a) of the Code, with the related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan are deductible by us when made, and contributions and earnings on those amounts are not generally taxable to the employees until withdrawn or distributed from the 401(k) plan.

Perquisites and Other Personal Benefits

We do not provide perquisites or other personal benefits to our named executive officers.

No Tax Gross-Ups

In 2020 and 2021, we did not make gross-up payments to cover our named executive officers’ personal income taxes that pertained to any of the compensation paid or provided by the Company.

Equity Compensation Plans

See our registration statement on Form S-1 that we filed with the SEC on May 23, 2019 for a description of the 2011 Plan, our amendment no. 1 to Form S-1 registration statement that we filed with the SEC on June 7, 2019 for a description of the 2019 Plan and ESPP, and our registration statement on Form S-8 that we filed with the SEC on May 7, 2020 for a description of the 2020 Plan.

Emerging Growth Company and Smaller Reporting Company Status

Our status as an “emerging growth company” and “smaller reporting company,” as defined in the Exchange Act, ended on December 31, 2021 because we had at least $700 million of equity securities held by non-affiliates on June 30, 2021. Pursuant to the rules, we are still permitted to use scaled disclosures in this proxy statement. Accordingly, we have provided certain scaled disclosures around executive compensation.

Non-Employee Director Compensation Policy

We have adopted a non-employee director compensation policy, pursuant to which our non-employee directors will be eligible to receive cash compensation and equity awards for service on our Board of Directors and committees of our Board of Directors. Our non-employee director compensation policy was most recently amended in February 2022.

Following the amendment in February 2022, each non-employee director receives an annual cash retainer of $40,000 for serving on our Board of Directors. The Lead Independent Director, as applicable, is entitled to a cash retainer of $60,000 in lieu of the annual retainer received by other non-employee directors for serving as our Lead Independent Director.

The Chair of the Board, as applicable, is entitled to a cash retainer of $80,000 in lieu of the annual retainer received by other non-employee directors for serving as our Chair.

The Chair and members of the three committees of our Board of Directors are entitled to the following additional annual cash retainers:


Board Committee	Chair Fee*		Member Fee
Audit Committee	$	20,000	$	10,000
Compensation Committee		15,000		7,500
Nominating and Corporate Governance Committee		10,000		5,000

*	Cash retainer for the Chair is in lieu of the annual

All annual cash compensation amounts are payable in equal quarterly installments in arrears no later than 30 days following the end of each fiscal quarter in which the service will occur, prorated for any partial quarter of service.

Under our non-employee director compensation policy, newly appointed or elected non-employee directors will automatically receive two initial equity awards as follows: (i) a nonstatutory stock option to purchase a number of shares of our common stock with a value of $125,000 determined using Black-Scholes’ valuation methodology based on the average closing price of our common stock over the 90 calendar days prior to the grant date and with such number of shares rounded down to the nearest whole share and (ii) a restricted stock unit award covering a number of shares of our common stock with a value of $125,000 determined by dividing such dollar value by the average closing price of our common stock over the 90 calendar days prior to the grant date and rounding down to the nearest whole share. Each initial equity award will vest in a series of three successive equal annual installments over the three-year period measured from the date of grant, such that the shares will be fully vested on the third anniversary of the date of grant, subject to the director’s continuous service (as defined in the 2019 Plan) on the Board of Directors through each such date.

Thereafter, at the close of business on the date of each annual meeting of our stockholders, each non-employee director continuing in office will automatically receive two annual equity awards as follows: (x) a nonstatutory stock option to purchase a number of shares of our common stock with a value of $82,500 determined using Black-Scholes’ valuation methodology based on the average closing price of our common stock over the 90 calendar days prior to the grant date and with such number of shares rounded down to the nearest whole share and (y) a restricted stock unit award

covering a number of shares of our common stock with a value of $82,500 determined by dividing such dollar value by the average closing price of our common stock over the 90 calendar days prior to the grant date and rounding down to the nearest whole share. Each annual equity award will vest upon the earlier of the one (1) year anniversary of the grant date or the day prior to our next annual meeting occurring after the grant date, subject to the director’s continuous service on the Board of Directors through each such date.

In addition, in the event of a change in control (as defined in the 2019 Plan) of the Company, the shares underlying such grants will vest and become exercisable immediately prior to the effectiveness of such change in control.

The exercise price per share of each stock option granted under the non-employee director compensation policy will be equal to 100% of the Fair Market Value (as defined in the 2019 Plan) of the underlying common stock on the date of grant. Each stock option will have a term of ten years from the date of grant, subject to earlier termination in connection with a termination of the non-employee director’s continuous service with us or a corporate transaction, each as provided under the 2019 Plan, except that the post-termination exercise period for each stock option granted pursuant to the non-employee director compensation policy shall equal the lesser of (i) 36 months from the date of termination of the Non-Employee Director’s Continuous Service for any reason other than removal with cause by a vote of the stockholders in accordance with our bylaws and (ii) the remaining period of the applicable stock option’s ten-year term.

TRANSACTIONS WITH RELATED PERSONS AND INDEMNIFICATION

The following is a summary of transactions since January 1, 2021, to which we have been a participant in which the amount involved exceeded or will exceed $120,000, and in which any of our directors, executive officers or holders of more than five percent of our capital stock, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest, other than compensation arrangements which are described in the sections titled “Executive Compensation” and “Director Compensation.”

Related Person Transactions Policy

In connection with our initial public offering, we adopted a written Related Person Transactions Policy that sets forth our policies and procedures regarding the identification, review, consideration, and approval or ratification of “related person transactions.” For purposes of our policy only, a “related person transaction” is a transaction, arrangement, or relationship (or any series of similar transactions, arrangements or relationships) in which we and any “related person” are, were or will be participants involving an amount that exceeds $120,000. Transactions involving compensation for services provided to us as an employee, director, consultant or similar capacity by a related person are not covered by this policy. A related person is any executive officer, director, or holder of 5% or more of our capital stock, including any of their immediate family members, and any entity owned or controlled by such persons.

Under the policy, each director and executive officer must identify, and we will request each significant stockholder to identify, any related person transaction involving such director or executive officer or his or her affiliates and immediate family members and must seek approval from the Audit Committee before he or she or, with respect to immediate family members or any of their affiliates, before they, may engage in the transaction. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to us of the transaction and whether any alternative transactions were available. In considering related person transactions, the Audit Committee takes into account the relevant available facts and circumstances including, but not limited to (a) the risks, costs and benefits to us, (b) the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated, (c) the terms of the transaction, (d) the availability of other sources for comparable services or products, and (e) the terms available to or from, as the case may be, unrelated third parties or to or from employees generally. In the event a director has an interest in the proposed transaction, the director must recuse himself or herself form the deliberations and approval. The policy requires that, in determining whether to approve, ratify or reject a related person transaction, the Audit Committee consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, the best interests of us and our stockholders, as the Audit Committee determines in the good faith exercise of its discretion.

Certain Transactions With or Involving Related Persons

Amended and Restated Investor Rights Agreement

We entered into an amended and restated investor rights agreement (the “IRA”), with certain holders of our convertible preferred stock, including certain holders of 5% or more of our capital stock and entities with which certain of our directors are affiliated. The IRA provides that the holders of common stock issuable upon conversion of our convertible preferred stock have the right to demand that we file a registration statement or request that their shares of common stock be covered by a registration statement that we are otherwise filing. In addition to registration rights, the IRA provided for certain information rights and a right of first offer. The provisions of the IRA, other than those related to registration rights, terminated upon the closing of our initial public offering in June 2019.

Indemnification Agreements

We have entered into separate indemnification agreements with our directors and officers in addition to the indemnification provided for in our bylaws. With certain exceptions, these agreements provide for indemnification for related expenses, including attorneys’ fees, judgments, fines, and settlement amounts incurred by any of these individuals in connection with any action, proceeding, or investigation. We believe that these indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Exchange Act requires that our executive officers, directors and 10% stockholders file reports of ownership and changes of ownership with the SEC. Such directors, executive officers and 10% stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

SEC regulations require us to identify in this proxy statement anyone who filed a required report late during the most recent fiscal year. Based solely on our review of the reports furnished to us and written representations that no other reports were required, we believe that during our fiscal year ended December 31, 2021, all Section 16(a) filing requirements were satisfied on a timely basis except one Form 4 was filed late by Mr. West for the exercise of 75,000 shares pursuant to his 10b5-1 trading Plan.

As of the date of this filing, the Company is aware of one late Section 16(a) filing for the year ended December 31, 2022, Mr. Moore’s initial statement of beneficial ownership on a Form 3 was filed after the time period allowed due to delays in receipt of Mr. Moore’s EDGAR codes from the SEC.

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 Personalis stockholders will be “householding” our 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, notify our Corporate Secretary at 1-650-752-1300 or send a written request to: Corporate Secretary at Personalis, 1330 O’Brien Drive, Menlo Park, California 94025. 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.

OTHER MATTERS

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

By Order of the Board of Directors,
