2024 ANNUAL MEETING OF STOCKHOLDERS
June 10, 2024

EXAGEN INC.
1261 LIBERTY WAY, VISTA, CALIFORNIA 92081


April 26, 2024

Dear Stockholder:

You are cordially invited to attend the Annual Meeting of Stockholders (the "Annual Meeting") of Exagen Inc., a Delaware corporation (the "Company"). The Annual Meeting is to be held on June 10, 2024 at 6:00 a.m. Pacific Time in the Exagen Administrative Offices, Training Room, 2175 Salk Avenue, 3rd Floor, Carlsbad, California 92008.

We have elected to take advantage of Securities and Exchange Commission rules that allow companies to furnish proxy materials to their stockholders by providing access to these documents on the Internet instead of mailing printed copies. Those rules allow a company to provide its stockholders with the information they need, while lowering the costs of delivery and reducing the environmental impact of the Annual Meeting. Most of our stockholders will not receive printed copies of our proxy materials unless requested, but instead will receive a notice with instructions on how they may access and review our proxy materials on the Internet and how they may cast their vote via the Internet. If you would like to receive a printed or e-mail copy of our proxy materials, please follow the instructions for requesting the materials in the Notice of Internet Availability that is being sent to you.

The Notice of Annual Meeting of Stockholders and proxy statement on the following pages describe the matters to be presented at the Annual Meeting. Please see the section entitled "Who Can Attend the Annual Meeting of Stockholders?" of the proxy statement for more information about how to attend the meeting in person. We may decide to hold the meeting in a different location or solely by means of remote communication (i.e., a virtual-only meeting). If we hold a virtual-only meeting, we will announce the decision to do so in advance, and details on how to participate will be set forth in a press release issued by us and available on our website (www.exagen.com) and on our proxy website (www.proxydocs.com/XGN).

Whether or not you attend the Annual Meeting, it is important that your shares be represented and voted at the Annual Meeting. Therefore, we urge you to promptly vote and submit your proxy by phone, via the Internet, or, if you received paper copies of these materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope, which requires no postage if mailed in the United States. If you have received our Notice of Internet Availability of Proxy Materials, the instructions regarding how you can access your proxy materials and vote are contained in that notice. If you have received written proxy materials, the instructions regarding how you can access our proxy materials and vote are contained on the proxy card. If you decide to attend the Annual Meeting, you will be able to vote in person, even if you have previously submitted your proxy. If you hold your shares through a bank or broker, you will need a proxy from your bank or broker to vote your shares in person at the Annual Meeting.

Thank you for your support.


Sincerely,

/s/ John Aballi

RECOMMENDATIONS OF THE BOARD
The Board recommends that you vote your shares as indicated below. If you return a properly completed proxy card or vote your shares by telephone or Internet, your shares of Common Stock will be voted on your behalf as you direct. If not otherwise specified, the shares of Common Stock represented by the proxies will be voted, and the Board recommends that you vote, as follows:
1.FOR each of the nominees for election as a Class II director as set forth in this proxy statement; and
2.FOR the ratification of the appointment of BDO USA, P.C. as our independent registered public accounting firm for the fiscal year ending December 31, 2024.

If any other matter properly comes before the stockholders for a vote at the Annual Meeting, the proxy holders named on the proxy card will vote your shares in accordance with their best judgment.


INFORMATION ABOUT THIS PROXY STATEMENT
Why you received this proxy statement. You are viewing or have received these proxy materials because the Board is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the Securities and Exchange Commission ("SEC") and that is designed to assist you in voting your shares.

Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, we are making this proxy statement and 2023 Annual Report available to our stockholders electronically via the Internet. On or about April 30, 2024, we will begin mailing to our stockholders a Notice of Internet Availability of Proxy Materials (the "Internet Notice") containing instructions on how to access this proxy statement and our 2023 Annual Report and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you on how to access and review all of the important information contained in the proxy statement and 2023 Annual Report. The Internet Notice also instructs you on how you may submit your proxy over the Internet. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained on the Internet Notice. We encourage our stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of our annual meetings and reduce the cost to us associated with the printing and mailing of materials.

Printed Copies of Our Proxy Materials. If you received printed copies of our proxy materials, then instructions regarding how you can vote are contained on the proxy card included in the materials.

Householding. The SEC's rules permit us to deliver a single Internet Notice or set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one Internet Notice or one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the Internet Notice or proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered. If you prefer to receive separate copies of the Internet Notice or proxy materials, we will provide copies of these documents, free of charge, upon written request to Exagen Inc., 1261 Liberty Way, Vista, California 92081. Such requests by street name holders should be made through their bank, broker or other holder of record.

Stockholders sharing an address that are receiving multiple copies of the Internet Notice can request delivery of a single copy of the proxy statement or 2023 Annual Report or Internet Notice by contacting their broker, bank or other intermediary or sending a written request to Exagen Inc. at the above address or by calling (760) 560-1501.

Questions and Answers about the Annual Meeting of Stockholders

Who is entitled to vote on matters presented at the Annual Meeting?
The Record Date for the Annual Meeting is April 15, 2024. You are entitled to vote on the matters presented at the Annual Meeting if you were a record holder at the close of business on the Record Date. Each outstanding share of Common Stock is entitled to one vote. At the close of business on the Record Date, there were 17,356,580 shares of Common Stock outstanding and entitled to vote at the Annual Meeting. Common Stock is our only class of stock entitled to vote.

What is the difference between being a "Record Holder" and holding shares in "Street Name"?
If, on the Record Date, your shares were registered directly in your name then you are a stockholder of record.

If, on the Record Date, your shares were held 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 these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting.

Am I entitled to vote if my shares are held in "Street Name"?
Yes. If your shares are held by a brokerage firm, bank, dealer or other similar organization, you are considered the “beneficial owner” of those shares held in “street name.” If your shares are held in street name, these proxy materials, along with instructions on how to vote your shares, are being provided to you by your brokerage firm, bank, dealer or other similar organization. As the beneficial owner, you have the right to direct your brokerage firm, bank, dealer or other similar organization how to vote your shares, and such organizations are required to vote your shares in accordance with your instructions. If your shares are held in street name, you may not vote your shares in person at the Annual Meeting, unless you obtain, and present at the Annual Meeting, a legal proxy from your brokerage firm, bank, dealer or other similar organization.

How many shares must be present to hold the Annual Meeting?
A quorum must be present at the Annual Meeting for any business to be conducted. Under Delaware law and our Amended and Restated Bylaws, as amended (the "Bylaws"), the presence at the Annual Meeting of the holders of a majority in voting power of the Common Stock issued and outstanding and entitled to vote, present in person, or by remote communication, if applicable, or represented by proxy, on the Record Date will constitute a quorum for the transaction of business at the Annual Meeting. The inspector of election will determine whether a quorum is present and will tabulate the votes cast at the Annual Meeting.

Who can attend the Annual Meeting of Stockholders?
You may attend the Annual Meeting only if you are a record holder or beneficial owner of our capital stock as of the Record Date. If you are a record holder you are entitled to vote at the Annual Meeting. If you hold your shares in street name you must obtain a valid proxy from your brokerage firm, bank, dealer or other similar organization to vote at the Annual Meeting. We currently intend to hold the Annual Meeting in person. However, we may decide to hold the meeting in a different location or as a virtual-only meeting. If we hold a virtual-only meeting, we will announce the decision to do so in advance, and details on how to participate will be set forth in a press release issued by us and available on our website (www.exagen.com) and on our proxy website (www.proxydocs.com/XGN). We encourage you to check this website prior to the meeting if you plan to attend.

In order to be admitted into the Annual Meeting, your name must appear on the attendance list and you must present government-issued photo identification (such as a driver’s license or passport). If your bank or broker holds your shares in street name, to attend the Annual Meeting you will also be required to present proof of beneficial ownership of our Common Stock on the Record Date, such as the Internet Notice you received from your bank or broker or a bank or brokerage statement or a letter from your bank or broker showing that you owned shares of our Common Stock at the close of business on the Record Date.
3



What if a quorum is not present at the Annual Meeting?
A quorum, once established at a meeting, will not be broken by the withdrawal of enough votes to leave less than a quorum. If a quorum is not present at the scheduled time of the Annual Meeting, (i) the Chairman of the Annual Meeting or (ii) the holders of a majority of the shares entitled to vote, present in person, or by remote communication, if applicable, or represented by proxy, at the Annual Meeting may adjourn the Annual Meeting until a quorum is present or represented. At such adjourned meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the meeting as originally noticed.

What does it mean if I receive more than one Internet Notice or more than one set of Proxy Materials?
It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.

How do I vote?
With respect to the election of directors, you may either vote "For" any one or more of the nominees to the Board or you may "Withhold" your vote for any one or more of the nominees. With respect to the ratification of the appointment of BDO USA, P.C. as our independent registered public accounting firm, you may vote "For," "Against" or "Abstain" from voting.

We recommend that stockholders vote by proxy even if they plan to attend the Annual Meeting and vote in person.

If you are a record holder, there are several ways for you to vote your shares:
•By Telephone: You can vote by telephone by calling 1-866-475-8889 and following the instructions provided in the Internet Notice or on the proxy card. Telephone voting facilities for stockholders of record will be available 24 hours a day, seven days a week. Votes can be made up until the start of the Annual Meeting at 5:59 a.m. Pacific Time on June 10, 2024.
•By Internet: You can vote over the Internet at www.proxypush.com/XGN by following the instructions provided in the Internet Notice or on the proxy card. Internet voting facilities for stockholders of record will be available 24 hours a day, seven days a week. Votes can be made up until the start of the Annual Meeting at 5:59 a.m. Pacific Time on June 10, 2024.
•By Mail: If you received a printed copy of the proxy materials, you can vote by mail by signing, dating and mailing the proxy card that accompanied the printed proxy materials and returning the proxy card in the self-addressed, postage-paid envelope provided. If you properly complete your proxy card and send it to us in time to vote, your proxy (one of the individuals named on your proxy card) will vote your shares as you have directed.
•In Person: You may still attend the meeting and vote in person even if you have already voted by proxy. We will provide you with a ballot at the Annual Meeting.

If you are a beneficial owner of shares that are held in street name through a brokerage firm, bank, dealer or other similar organization, you will receive instructions on how to vote from that organization rather than from us. You must follow their instructions in order for your shares to be voted. Generally, you will have three options for returning your proxy and voting your shares.
•By the Method Listed on your Voting Instruction Card: Please refer to your voting instruction card or other information provided by your bank, broker or other agent to determine whether you may vote by telephone or electronically on the Internet and follow the instructions on the voting instruction card or other information provided by your broker, bank or other agent. A large number of banks and brokerage firms offer Internet and telephone voting. If your bank, broker or other agent does not offer Internet or telephone voting information, please follow the other voting instructions they provide to vote your shares.
•By Mail: You may vote by signing, dating and returning your voting instruction card in the pre-addressed envelope provided by your broker, bank or other agent.
4


•In Person: If you would like to vote your shares in person at the Annual Meeting, you will need to contact your brokerage firm, bank, dealer or other similar organization to obtain a legal proxy and bring it to the Annual Meeting in order to vote.

Can I change my vote after I submit my Proxy?
Yes. If you are a record holder, you may revoke your proxy and change your vote any time before the proxy is voted at the Annual Meeting:
•by submitting a duly executed proxy bearing a later date than your prior proxy;
•by granting a subsequent proxy through the Internet or telephone;
•by giving written notice of revocation to the Corporate Secretary of the Company prior to or at the Annual Meeting; or
•by voting in person at the Annual Meeting.

We may decide to hold the meeting in a different location or as a virtual-only meeting. If we hold a virtual-only meeting, we will announce the decision to do so in advance, and details on how to participate will be set forth in a press release issued by us and available on our website (www.exagen.com) and on our proxy website (www.proxydocs.com/XGN).

Your most recent proxy card or telephone or Internet proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote in person at the Annual Meeting by obtaining a legal proxy from your bank or broker and submitting the legal proxy along with your ballot at the Annual Meeting.

Who will count the votes?
Mediant Communications, Inc. is expected to tabulate the votes and an employee of the Company is expected to be our inspector of election and will certify the votes.

What if I do not specify how my shares are to be voted?
If you are a record holder and you indicate when voting on the Internet or by telephone that you wish to vote as recommended by the Board, then your shares will be voted at the Annual Meeting in accordance with the Board’s recommendation on all matters presented for a vote at the Annual Meeting. Similarly, if you are a record holder and submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board’s recommendations are indicated on page 2 of this proxy statement, along with the description of each proposal in this proxy statement.

If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions, then, the organization that holds your shares may generally vote your shares in their discretion on “routine” matters but cannot vote on “non-routine” matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, that organization will inform the inspector of election that it does not have the authority to vote on that matter with respect to your shares. This is generally referred to as a “broker non-vote.”

What are broker non-votes and do they count for determining a quorum?
Shares represented by proxies that reflect a broker non-vote will be counted as present for purposes of determining the presence of a quorum. As discussed above, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because (1) the broker has not received voting instructions from the beneficial owner and (2) the broker lacks discretionary voting power to vote those shares on a particular matter. A broker has discretionary power to vote shares without instruction from the beneficial owner on routine matters, such as the ratification of the appointment of BDO USA, P.C. as our independent registered public accounting firm. Thus, broker non-votes are not expected on that proposal. However, if a broker does not exercise this authority, such broker non-votes are not considered to be votes cast and will have
5


no effect on that proposal. Absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters. Broker non-votes on the election of directors, a non-routine matter, will have no effect because they are not considered a vote cast, and the three directors that receive the highest number of votes will be elected.

What is an Abstention and how will votes Withheld and Abstentions be treated?
Shares of Common Stock held by persons attending the Annual Meeting but not voting, and shares represented by proxies that reflect withheld votes or abstentions as to a particular proposal, will be counted as present for purposes of determining the presence of a quorum. A vote "withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the ratification of the appointment of BDO USA, P.C., represents a stockholder's affirmative choice to decline to vote on a proposal. Votes withheld have no effect on the election of directors, as the three directors that receive the highest number of votes will be elected, and abstentions are not considered to be votes cast and will have no effect on the ratification of the appointment of BDO USA, P.C.

How many votes are required for the approval of the proposals to be voted upon and how will Abstentions and Broker Non-Votes be treated?
ProposalVotes RequiredEffect of Votes Withheld / Abstentions and Broker Non-Votes
Proposal 1: Election of Directors
The plurality of the votes cast. This means that the three nominees receiving the highest number of affirmative "FOR" votes will be elected as Class II directors.
Votes withheld and broker non-votes will have no effect.
Proposal 2: Ratification of Appointment of Independent Registered Public Accounting FirmThe affirmative vote of a majority of the votes cast for or against the matter.Abstentions and broker non-votes will have no effect. We do not expect any broker non-votes on this proposal.

Will any other business be conducted at the Annual Meeting?
We currently know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.

Where can I find the voting results of the Annual Meeting of Stockholders?
We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC 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 Annual Meeting, we intend to file a Form 8-K to publish the 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.

Proposals To Be Voted On

Proposal 1 - Election of Directors
At the Annual Meeting, three (3) Class II directors are to be elected to hold office for three-year terms expiring at the Annual Meeting of Stockholders to be held in 2027 and until each such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal. Based on the recommendation of the Nominating and Corporate Governance Committee of the Board (the "Nominating Committee"), the Board has nominated Ana Hooker, Paul Kim and Frank Stokes for re-election as Class II directors at the Annual Meeting.

Our Amended and Restated Certificate of Incorporation (the “Charter”) and Bylaws provide that the authorized number of directors shall be fixed from time to time exclusively by resolution adopted by the Board. As of the date hereof, we have nine (9) authorized directors on our Board. Between April 22, 2024 and April 23, 2024, Brian Birk, Wendy Johnson and Ebetual Pallares, Ph.D. notified the Board of each of their decisions to resign as members of the Board, including all committees thereof, effective as of the date of the Annual Meeting. On April 25, 2024, upon the recommendation of the Nominating Committee, and pursuant to the bylaws of the Company, the Board appointed, effective as of the date of the Annual Meeting, Scott D. Kahn, Ph.D., to serve as a Class I director. Immediately following such resignations and appointment, the size of the Board will be reduced to seven (7) members. As set forth in our Charter, the Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election, until such director's successor is elected and qualified or until such director's earlier death, resignation or removal. The following table summarizes the class, independence and committee membership of our director nominees and those directors whose terms will begin, or will not end, at the Annual Meeting:

NameAgePositionIndependentCommittee Membership

CLASS I DIRECTORS - Terms to Expire at the 2026 Annual Meeting
Tina S. Nova, Ph.D.70Executive Chairman of the Board
Scott D. Kahn, Ph.D.64DirectorXCompensation, Nominating and Governance

The division of our Board into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of our Company. Our directors may be removed only for cause and only by the affirmative vote of the holders of at least two-thirds of the voting power of the then-outstanding shares of capital stock entitled to vote in the election of directors.

In the event any of the nominees should become unable to serve, or will not serve, as a director, it is intended that votes will be cast for a substitute nominee designated by the Board or the Board may elect to reduce its size. The Board has no reason to believe that the nominees named below will be unable to serve if elected. Each of the nominees has consented to being named in this proxy statement and to serve if elected.

Each of our directors and director nominees brings to the Board significant leadership experience derived from their professional experience and service as executives or board members of other companies. The process undertaken by the Nominating and Corporate Governance Committee in recommending qualified director candidates is described below under "Board Diversity and Director Nomination Process." Certain individual qualifications and
7


skills of our directors that contribute to the board of directors' effectiveness as a whole are described in the following paragraphs.

Proposal 2 - Ratification of Appointment of Independent Registered Public Accounting Firm
The Audit Committee of the Board (the "Audit Committee") has appointed BDO USA, P.C. as our independent registered public accounting firm for the fiscal year ending December 31, 2024. The Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of our appointment of BDO USA, P.C. is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

BDO USA, P.C. has served as our independent registered public accounting firm since 2017. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit services. A representative of BDO USA, P.C. is expected to attend the Annual Meeting and to have an opportunity to make a statement if they intend to do so. This representative will also be available to respond to appropriate questions from stockholders.

In the event that the appointment of BDO USA, P.C. is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent registered public accounting firm for the fiscal year ending December 31, 2024. Even if the appointment of BDO USA, P.C. is ratified, the Audit Committee retains the discretion to appoint a different independent registered public accounting firm at any time if it determines that such a change is in the interests of the Company.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF BDO USA, P.C. AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM, AND PROXIES SOLICITED BY THE BOARD WILL BE VOTED IN FAVOR THEREOF UNLESS A STOCKHOLDER HAS INDICATED OTHERWISE ON THE PROXY.


Independent Registered Public Accounting Firm Fees and Other Matters
The following table summarizes the fees of BDO USA, P.C., our independent registered public accounting firm, billed to us for each of the last two fiscal years for audit and other services:
Fiscal Year Ended December 31,
Fee Category20232022
Audit Fees(1)$581,461 $578,806 
Audit-Related Fees— — 
Tax Fees— — 
All Other Fees— — 
Total Fees$581,461 $578,806 
(1) Audit fees consist of fees for the audit of our financial statements, the review of the unaudited interim financial statements included in our quarterly reports on Form 10-Q and the issuance of consents and comfort letters in connection with registration statements.

The Audit Committee has considered whether the provision of non-audit services is compatible with maintaining the independence of BDO USA, P.C., and has concluded that the provision of such services is compatible with maintaining the independence of our auditors.

11



Audit Committee Pre-Approval of Audit and Non-Audit Services
The Audit Committee has established a policy that prior to engagement of an independent registered public accounting firm for the next year's audit, management will submit an aggregate of services expected to be rendered during that year for each of four categories of services to the Audit Committee for approval.

1.Audit services include audit work performed in the preparation of financial statements, as well as work that generally only an independent registered public accounting firm can reasonably be expected to provide, including comfort letters, statutory audits, and attest services.
2.Audit-Related services are for assurance and related services that are traditionally performed by an independent registered public accounting firm, including due diligence related to mergers and acquisitions, employee benefit plan audits, and special procedures required to meet certain regulatory requirements.
3.Tax services include all services performed by an independent registered public accounting firm's tax personnel except those services specifically related to the audit of the financial statements, and includes fees in the areas of tax compliance, tax planning, and tax advice.
4.Other Fees are those associated with services not captured in the other categories. The Company generally does not request such services from our independent registered public accounting firm.

The Audit Committee pre-approves the engagement of the independent registered public accounting firm and the provision of audit services and audit-related services on an annual basis. The Audit Committee also pre-approves the particular tax and all other services on a case-by-case basis and does not delegate approval to management. All of the services of BDO USA, P.C., for fiscal years ended December 31, 2023 and 2022 described above were pre-approved by the Audit Committee in accordance with this policy.

The Audit Committee considers whether the provision of each non-audit service is compatible with maintaining the independence of our auditors. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. Our independent registered public accounting firm and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date.

Report of the Audit Committee of the Board
The Audit Committee has reviewed the Company’s audited financial statements for the fiscal year ended December 31, 2023 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company’s independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by statement on Auditing Standards No. 1301 (Communications with Audit Committees), as adopted by the Public Company Accounting Oversight Board (“PCAOB”). The Audit Committee is not employed by the company, nor does it provide any expert assurance or professional certification regarding the company’s financial statements. The Audit Committee relies, without independent verification, on the accuracy and integrity of the information provided, and representations made, by management and the Company’s independent registered public accounting firm.

The Company’s independent registered public accounting firm also provided the Audit Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from Exagen Inc. The Audit Committee also considered whether the independent registered public accounting firm’s provision of certain other non-audit related services to the Company is compatible with maintaining such firm’s independence.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The Audit Committee and the Board have also recommended, subject to stockholder approval, the ratification of the appointment of BDO USA, P.C. as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024.

This report of the Audit Committee is not “soliciting material,” shall not be deemed “filed” with the SEC and shall not be incorporated by reference by any general statement incorporating by reference this proxy statement into any filing under the Securities Act of 1933, as amended (the "Securities Act"), or the Securities Exchange Act of 1934, as amended (the "Exchange Act"), whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under such acts.

The foregoing report has been furnished by the Audit Committee.

Corporate Governance

General
The Board has adopted Corporate Governance Guidelines, a Code of Conduct and Ethics and charters for our Nominating Committee, Audit Committee and Compensation Committee of the Board (the "Compensation Committee") to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines and our Code of Conduct and Ethics in the “Corporate Governance” section of the “Investors” page of our website located at www.exagen.com, or by writing to our Corporate Secretary at our offices at 1261 Liberty Way, Vista, CA 92081. Please note, however, that the information contained on the website is not incorporated by reference in, or considered part of, this proxy statement.


Director Independence
The Board currently consists of nine members. The Board has determined that Dr. Kahn and all of our current directors, other than Mr. Aballi and Dr. Nova, are independent directors in accordance with the listing requirements of the Nasdaq Global Market ("Nasdaq"). The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, the Board has made a subjective determination as to each independent director and director nominee that no relationships exist, which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, the Board reviewed and discussed information provided by the directors (and director nominee) and us with regard to each director’s or director nominee's business and personal activities and relationships as they may relate to us and our management. There are no family relationships among any of our directors, director nominees or executive officers.


Board Diversity and Director Nomination Process
Our Nominating Committee is responsible for reviewing with the Board, on an annual basis, the appropriate characteristics, skills and experience required for the board of directors as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current members) for election or
14


appointment, the Nominating Committee, in recommending candidates for election, and the Board will take into account many factors, including the following:
•personal and professional integrity, ethics and values;
•experience in corporate management, such as serving as an officer or former officer of a publicly-held company;
•experience as a board member or executive officer of another publicly-held company;
•strong finance experience;
•diversity of expertise and experience in substantive matters pertaining to our business relative to other board members;
•diversity of background and perspective, including, but not limited to, with respect to age, gender, race, place of residence and specialized experience;
•experience relevant to our business industry and with relevant social policy concerns; and
•relevant academic expertise or other proficiency in an area of our business operations.

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

Other than the foregoing, there are no stated minimum criteria for director nominees, although the Nominating Committee may also consider such other factors as it may deem to be in the best interests of our Company and our stockholders. The Nominating Committee does, however, believe it appropriate for at least one member of our Board to meet the criteria for an “audit committee financial expert” as defined by SEC rules, and that a majority of the members of our Board meet the definition of “independent director” under Nasdaq qualification standards. The Nominating Committee also believes it is appropriate for our President and Chief Executive Officer to serve as a member of our Board. As of April 15, 2024, three of our nine directors self-identified as female and five of our nine directors self-identified as members of an "underrepresented community" as defined in the California Corporations Code or an "underrepresented minority" as defined under Nasdaq board diversity requirements. The Board Diversity Matrix, below, provides the diversity statistics of our Board.

Identification and Evaluation of Nominees for Directors
15


The Nominating Committee identifies nominees for director by first evaluating the current members of our Board willing to continue in service. Current members with qualifications and skills that are consistent with the Nominating Committee's criteria for Board service and who are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of our Board with that of obtaining a new perspective or expertise.

If any member of our Board does not wish to continue in service or if our Board decides not to re-nominate a member for re-election or if the Board decides to expand its size, the Nominating Committee identifies the desired skills and experience of a new nominee in light of the criteria above. The Nominating Committee generally polls our Board and members of management for their recommendations. The Nominating Committee may also review the composition and qualification of the boards of directors of our competitors and may seek input from industry experts or analysts. The Nominating Committee reviews the qualifications, experience and background of the candidates. Final candidates are interviewed by the members of the Nominating Committee and by certain of our other independent directors and executive management. In making its determinations, the Nominating Committee evaluates each individual in the context of our Board as a whole, with the objective of assembling a group that can best contribute to the success of our Company and represent stockholder interests through the exercise of sound business judgment. After review and deliberation of all feedback and data, the Nominating Committee makes its recommendation to our Board.

We have not received director candidate recommendations from our stockholders, and we do not have a formal policy regarding consideration of such recommendations. However, any recommendations received from stockholders will be evaluated in the same manner that potential nominees suggested by members of our Board, management or other parties are evaluated.

Under our Bylaws, a stockholder wishing to suggest a candidate for director should write to our Corporate Secretary and provide such information about the stockholder and the proposed candidate as is set forth in our Bylaws and as would be required by SEC rules to be included in a proxy statement. In addition, the stockholder must include the consent of the candidate and describe any arrangements or undertakings between the stockholder and the candidate regarding the nomination. In order to give the Nominating Committee sufficient time to evaluate a recommended candidate and include the candidate in our proxy statement for the 2025 annual meeting of stockholders (the "2025 Annual Meeting"), the recommendation should be received by our Corporate Secretary at our principal executive offices in accordance with our procedures detailed in the section below entitled "Stockholder Proposals."


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

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that our Corporate Secretary and Executive Chairman of the Board consider to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications. Stockholders who wish to send communications on any topic to the Board should address such communications to the Board in writing: c/o Corporate Secretary, Exagen Inc., 1261 Liberty Way, Vista, California 92081.


Director Attendance at Annual Meetings
Although we do not have a formal policy regarding attendance by members of our Board at our Annual Meeting, we strongly encourage, but do not require, our directors to attend. Nine members of our Board attended our 2023 Annual Meeting of Stockholders.

Board Leadership Structure - Separate Executive Chairman
The Board is currently led by its Executive Chairman, Tina S. Nova, Ph.D. The Board recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as we continue to grow. We separate the roles of Chief Executive Officer and Executive Chairman of the Board in recognition of the differences between the two roles. The Chief Executive Officer is responsible for setting the strategic direction for our Company and the day-to-day leadership and performance of our Company, while the Executive Chairman of the Board provides guidance to the Chief Executive Officer and presides over meetings of the full Board. We believe that this separation of responsibilities provides a balanced approach to managing the Board and overseeing our Company.

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


Role of Board in Risk Oversight Process
The Board has responsibility for the oversight of our risk management processes and, either as a whole or through its committees, regularly discusses with management our major risk exposures, their potential impact on our business and the steps we take to manage them. The risk oversight process includes receiving regular reports from Board committees and members of senior management to enable the Board to understand our risk identification, risk management and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, strategic and reputational risk.

The Audit Committee reviews information regarding liquidity and operations and oversees our management of financial risks. Periodically, the Audit Committee reviews our policies with respect to risk assessment, risk management, loss prevention and regulatory compliance. Oversight by the Audit Committee includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the actions management has taken to limit, monitor or control such exposures. The Compensation Committee is responsible for assessing whether any of our compensation policies or programs has the potential to encourage excessive risk-taking. The Nominating Committee manages risks associated with the independence of the Board, corporate disclosure practices, and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered by the Board as a whole.


Annual Board Evaluation
Our Corporate Governance Guidelines require the Nominating Committee to oversee an annual assessment by the Board of the Board’s performance. As provided in our Corporate Governance Guidelines, the Nominating Committee is responsible for establishing the evaluation criteria and implementing the process for such evaluation.


Code of Ethics
We have a written Code of Conduct and Ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. We have posted a current copy of the code in the "Corporate Governance" section of the "Investors" page on our website located at www.exagen.com.

In addition, we intend to post on our website all disclosures that are required by law or the listing standards of Nasdaq concerning any amendments to, or waivers from, any provision of the code.


Policy Prohibiting Hedging
17


Our Insider Trading Compliance Policy applies to all officers, directors, employees of the Company and certain consultants specified by management and prohibits all hedging transactions involving the Company's equity securities, such as zero-cost collars and forward sale contracts.


Attendance by Members of the Board of Directors at Meetings
There were seven meetings of the Board (including telephonic meetings) during the fiscal year ended December 31, 2023. During the fiscal year ended December 31, 2023, each director attended at least 75% of the aggregate of all meetings of the Board and each director attended as least 75% of meetings of the committees on which such director served, during the period in which he or she served as a director.

The Compensation Committee has the authority to retain or obtain the advice of compensation consultants, legal counsel and other advisors to assist in carrying out its responsibilities. In 2023, the Compensation Committee engaged Frederick W. Cook & Co., Inc. (“FW Cook"), an independent compensation consultant, to assist in making decisions regarding the amount and types of compensation to provide our executives and non-employee directors. As part of this process, the Compensation Committee reviewed a compensation assessment provided by FW Cook which compared our compensation to that of a group of peer companies within our industry. The Compensation Committee also met with FW Cook to discuss our executive and non-employee director compensation and receive input and advice. FW Cook reported directly to the Compensation Committee.

The members of our Compensation Committee are Dr. Robertson, Ms. Hooker and Mr. Kim. Dr. Robertson serves as the Chairman of the committee. Effective as the Company’s Annual Meeting, Ms. Hooker will resign as Chairman and as a member of the Compensation Committee and Dr. Kahn will become a member of the Compensation Committee.

Narrative Disclosure to Summary Compensation Table
Base Salaries

The named executive officers receive a base salary to compensate them for services rendered to our company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. The Board made no increases to annual base salaries in 2023. The 2023 base salaries of our named executive officers were $525,000, $406,477 and $378,416 for Messrs. Aballi, Adawi and Hazeltine, respectively.

We expect that base salaries for our named executive officers will continue to be reviewed periodically by our Compensation Committee, with adjustments expected to be made generally in accordance with the considerations described above and to maintain base salaries at competitive levels.

Cash Bonuses
22



Our named executive officers are eligible to earn cash bonuses based on corporate and individual performance measures for the applicable year which, at the discretion of the Compensation Committee, may be further adjusted based on the individual performances of each named executive officer. For 2023, Mr. Aballi was eligible to receive a target bonus of up to 50% of his base salary, and each of Messrs. Adawi and Hazeltine were eligible to receive target bonuses of up to 45% of their base salaries.

For 2023, annual bonus payments were based in part on the achievement of pre-established objective performance goals for revenue, Adjusted EBITDA, cash balance, trailing-twelve-month average sales price, cost of sales and employee turnover, weighted 20%, 20%, 20%, 13.3%, 13.3% and 13.3%, respectively, to determine each executive's bonus opportunity. Award opportunities for each goal were established at target and maximum levels. Achievement at or above maximum for each goal was capped at 150% of target. Straight-line interpolation is used to calculate the 2023 bonus payouts associated with actual results falling between goals. The goals were set at levels that were expected to be challenging but achievable at the outset of the year.

In 2023, actual performance of our goals for revenue, Adjusted EBITDA, cash balance, trailing-twelve-month average sales price, cost of sales and employee turnover, were achieved at 115%, 145%, 135%, 109%, 93% and 113%, respectively, of the target goals.

For 2023, the Compensation Committee authorized awarding Messrs. Aballi and Adawi with discretionary bonuses of $76,125 and $34,799, respectively. The Compensation Committee reviewed each named executive officer's individual performance and contributions to the Company's success, and believed these payments recognized management's achievements in 2023, including record total revenue and record AVISE CTD tests, which we believe will contribute to long-term shareholder returns. The following table shows information regarding grants of non-equity incentive plan awards that we made during the fiscal year ended December 31, 2023 to each of our executive officers.

Equity Compensation

We award stock options and restricted stock unit awards to our employees, including our named executive officers, as the long-term incentive component of our compensation program. Awards granted since our initial public offering in September 2019 were granted under our 2019 Incentive Award Plan (the “2019 Plan”); prior to our initial public offering, awards were granted under the 2013 Stock Option Plan, as amended from time to time (the “2013 Plan”) and our 2002 Stock Option Plan (the “2002 Plan”).

We typically grant equity awards to key new hires upon their commencing employment with us. We historically have used stock options as the primary incentive for long-term compensation to our named executive officers. Generally, the stock options we grant vest as to 25% of the total number of option shares on the first anniversary of the date of grant and in equal monthly installments over the 36 months thereafter, subject to the employee’s continued service with us on each vesting date. Since 2021, we have used restricted stock units as the primary long-term compensation to our named executive officers. Generally, the restricted stock units we grant vest as to 25% of the total number of restricted stock units on the first anniversary of the first day of the month in which such restricted stock units were granted and in annual installments over the four years thereafter, subject to the employee's continued service with us on each vesting date.

There were no options granted to our named executive officers in 2023.

Restricted stock units and stock options granted to our named executive officers may be subject to accelerated vesting in connection with the termination of their services with the Company. For additional discussion, please see “—Other Elements of Compensation—Severance and Change in Control Benefits” below.

Amounts for 2023 represent the aggregate grant date fair value of restricted stock unit awards granted to the named executive officer in the applicable year, as computed in accordance with ASC Topic 718, Compensation-Stock Compensation, rather than the amounts paid to or realized by the named executive officer. For a discussion of valuation assumptions used in the calculations, see Note 2 and Note 9 to our audited financial statements in our Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on March 18, 2024.

Other Elements of Compensation

Retirement Plans

We currently maintain a 401(k) retirement savings plan that allows eligible employees to defer a portion of their compensation, within limits prescribed by the Code, on a pre-tax basis through contributions to the plan. Our named executive officers are eligible to participate in the 401(k) plan on the same terms as other full-time employees generally. Currently, we make employer matching contributions under the 401(k) plan up to a specified percentage, and these matching contributions are fully vested as of the date on which the contribution is made. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan, and making matching contributions, adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

Employee Benefits and Perquisites

Our named executive officers are eligible to participate in our health and welfare plans to the same general extent as all full-time employees, including:
•medical, dental and vision benefits;
•medical and dependent care flexible spending accounts;
•short-term and long-term disability insurance;
•life insurance and accidental death and dismemberment insurance; and
•paid-time-off

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

No Tax Gross-Ups

We generally have not made gross-up payments to cover our named executive officers’ personal income taxes that may pertain to any of the compensation paid or provided by our company.

Severance and Change in Control Benefits

Our named executive officers may become entitled to certain benefits or enhanced benefits upon a termination of employment pursuant to the Exagen Inc. Amended and Restated Executive Change in Control and Severance Plan (the "Amended and Restated Severance Plan"), as explained in further detail below. In addition, stock options granted to our employees, including our named executive officers, may be subject to acceleration in connection with a change in control under our equity plans.
24



On April 25, 2022, the Compensation Committee adopted the Amended and Restated Severance Plan. The Amended and Restated Severance Plan is intended to provide severance protections to a select group of management or highly compensated employees, including our named executive officers, in the event of a qualifying termination of employment with us. The Amended and Restated Severance Plan superseded any and all severance plans, separation policies, the provisions of any offer letters or any agreement that provided for severance payments and benefits applying to our executives who are party to the Amended and Restated Severance Plan.

Under the Amended and Restated Severance Plan, in the event that we terminate an executive's employment without "cause" and at any time, other than within twelve months following a "change in control," the executive will be eligible to receive the following payments and benefits:
•a cash payment equal to 50% (or, for Mr. Aballi, 75%) of the executive's then-current annual base salary rate for the year in which the termination occurs, to be paid in a lump sum on the 30th day following the executive's termination;
•a cash payment equal to the executive's pro-rated cash performance bonus (based on actual performance) for the year in which the termination occurs, to be paid on the date on which annual bonuses are generally paid but no later than March 15 of the year following the year of the executive's termination; and
•Company-subsidized premium payments under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), for the executive and his or her covered dependents for up to 6 (or, for Mr. Aballi, 9) months.

The Amended and Restated Severance Plan also provides that in the event of a termination of an executive's employment by us without "cause" or by the executive for "good reason," in either case, on or within twelve months following a "change in control," the executive will be eligible to receive the following payments and benefits:
•a cash payment equal to 100% (or, for Mr. Aballi, 125%) of the executive's then-current annual base salary rate for the year in which the termination occurs, to be paid in a lump sum on the 30th day following the executive's termination;
•a cash payment equal to the executive's pro-rated cash performance bonus (based on actual performance) for the year in which the termination occurs, to be paid on the date on which annual bonuses are generally paid but no later than March 15 of the year following the year of the executive's termination;
•Company-subsidized COBRA premium payments for the executive and his or her covered dependents for up to 12 (or, for Mr. Aballi, 15) months; and
•full accelerated vesting of all outstanding equity awards that vest solely based on the passage of time.

The executive's right to receive the severance payments and benefits described above is subject to the executive's delivery and, as applicable, non-revocation of a general release of claims in our favor and the executive's continued compliance with any applicable restrictive covenants.

In addition, in the event that any payment under the Amended and Restated Severance Plan, together with any other amounts we paid to the executive, would subject the executive to an excise tax under Section 4999 of the Internal Revenue Code, such payments will be reduced to the extent that such reduction would produce a better net after-tax result for the executive.

In connection with Mr. Hazeltine’s resignation, the Company and Mr. Hazeltine entered into a consulting agreement (the “Consulting Agreement”) and a severance agreement (the “Severance Agreement”). Pursuant to the Consulting Agreement, among other things, (i) each of Mr. Hazeltine’s unvested stock options and restricted stock awards continued to vest during the term of the Consulting Agreement, and (ii) from December 6, 2023 to March 31, 2024, Mr. Hazeltine provided consulting services to the Company at an hourly rate of $243.00. The Severance Agreement provided, among other things, that Mr. Hazeltine was entitled to receive, in accordance with the Severance Plan, the following cash payments: (i) $202,441.56, which is equivalent to six months of his then-current annual base salary and (ii) $182,197.40, which is equivalent to 100% of his cash performance bonus for 2023.

For additional discussion, please see “Equity Compensation” and "Outstanding Equity Awards at 2023 Fiscal Year-End." Other than the benefits described above, none of our named executive officers are entitled to any severance or change in control benefits.

Director Compensation
27


Our director compensation program is intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors' interests with those of our stockholders. Directors who are also employees of our Company do not receive compensation for their service on the Board.

In September 2019, the Board adopted the Non-Employee Director Compensation Program (the "Director Compensation Program") that became effective in connection with our initial public offering.

Under the Director Compensation Program, non-employee directors receive a cash retainer for service on the Board and for service on each committee of which the director is a member. The Chairman of the Board and of each committee receives a higher retainer for such service. In connection with Dr. Nova’s appointment as Executive Chairman of the Board, the Board approved an aggregate annual cash retainer of $100,000 for Dr. Nova in lieu of any retainer under the director compensation program. Cash retainers are payable quarterly in arrears. Annual cash retainers are pro-rated for any partial calendar quarter of service. All cash compensation payable to the directors affiliated with Sun Mountain Capital or H.I.G. Capital, LLC is paid to Sun Mountain Capital or H.I.G. Capital, LLC, as applicable. The fees paid to non-employee directors for service on the Board under the Director Compensation Program are as follows:

Cash Compensation
Non-Employee Director annual retainer$50,000 
Incremental annual retainer for the Chairman$20,000 
Committee Chair incremental annual retainers
Audit$12,000 
Compensation$10,000 
Nominating and Corporate Governance$9,000 
Committee member incremental annual retainers
Audit$7,500 
Compensation$7,500 
Nominating and Corporate Governance$7,500 

In addition, under this program, each of our non-employee directors is eligible to receive an annual stock option grant to purchase 9,000 shares of our Common Stock, which shall vest in full on the earlier to occur of (i) the one-year anniversary of the applicable grant date and (ii) the date of the next annual meeting following the grant date, subject to continued service through the applicable vesting date. Additionally, new non-employee directors are eligible to receive a stock option to purchase 15,000 shares of our Common Stock on the date on which such eligible director is appointed or elected to serve on the Board, and shall vest as to 1/36th of the shares underlying the option on each monthly anniversary of the grant date, subject to the eligible director's continued service through the applicable vesting date.

The following table sets forth information regarding the compensation of our non-employee directors earned for services rendered during the year ended December 31, 2023. Mr. Aballi, who served as our President and Chief Executive Officer during the year ended December 31, 2023, did not receive additional compensation for his service as a director, and therefore is not included in the Director Compensation table below. The compensation paid to Mr. Aballi is reported above in the “Summary Compensation Table.”

Amounts reflect the aggregate grant date fair value of stock options granted in 2023, computed in accordance with the provisions of ASC Topic 718, Compensation Stock Compensation.

The assumptions that we used to calculate these amounts are discussed in Note 2 and Note 9 to our audited financial statements in our Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on March 18, 2024.

Security Ownership of Certain Beneficial Owners and Management
The following table and accompanying footnotes set forth certain information with respect to the beneficial ownership of our Common Stock at April 15, 2024 for:
•each of our directors and nominees for director;
•each of our named executive officers;
•all of our current directors and executive officers as a group; and
•each person, or group of affiliated persons, who beneficially owned more than 5% of our outstanding Common Stock.

We have determined beneficial ownership in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons and entities named in the table below have sole voting and sole investment power with respect to all shares of Common Stock that they beneficially owned, subject to applicable community property laws.

Applicable percentage ownership is based on 17,356,580 shares of Common Stock outstanding as of April 15, 2024. In computing the number of shares of Common Stock beneficially owned by a person and the percentage ownership of that person, we deemed to be outstanding all shares of Common Stock subject to options, warrants or other rights held by that person or entity that are currently exercisable or scheduled to vest within 60 days of April 15, 2024. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Exagen Inc., 1261 Liberty Way, Vista, California 92081.

Certain Relationships and Related Party Transactions
There are and have been no transactions entered into or existing since January 1, 2022 to which we have been a party in which the amount involved exceeded or will exceed $120,000 (or, if less, 1% of the average of our total assets amounts for the years ended December 31, 2023 and 2022), and in which any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our capital stock or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest, other than equity and other compensation, termination, change in control and other arrangements, which are described under “Executive and Director Compensation.”

Policies and Procedures for Related Person Transactions

The Board adopted a written related person transaction policy, setting forth the policies and procedures for the review and approval or ratification of related-person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships in which we were or are to be a participant, where the amount involved exceeds $120,000 (or, if less, 1% of the average of our total assets at year-end for the last two completed fiscal years) and a related person had or will have a direct or indirect material interest, including, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person. In reviewing and approving any such transactions, our Audit Committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction.


Stockholder Proposals
Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2025 Annual Meeting pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to our Corporate Secretary at our offices at 1261 Liberty Way, Vista, CA 92081 in writing not later than December 31, 2024, which is 120 days prior to the one-year anniversary of the mailing date of the proxy statement for the Annual Meeting, unless the date of the 2025 Annual Meeting of Stockholders is changed by more than 30 days from the anniversary of our Annual Meeting, in which case the deadline for such proposals will be a reasonable time before we begin to print and send our proxy materials. These proposals must comply with the requirements as to form and substance established by the SEC in Rule 14a-8 of the Exchange Act for such proposals in order to be included in the proxy statement.

Stockholders intending to present a proposal at the 2025 Annual Meeting, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that our Corporate Secretary receive written notice from the stockholder of record of their intent to present such proposal or nomination not earlier than the close of business on the 120th day and not later than the close of business on the 90th day prior to the anniversary of the preceding year’s annual meeting. Therefore, the Company must receive notice of such a proposal or nomination for the 2025 Annual Meeting no earlier than the close of business on February 9, 2025 and no later than the close of business on March 11, 2025. The notice must contain the information required by the Bylaws, a copy of which is available upon request to our Corporate Secretary. In the event that the date of the 2025 Annual Meeting is more than 30 days before or more than 60 days after June 9, 2025, our Corporate Secretary must receive such written notice not earlier than the close of business on the 120th day prior to the 2025 Annual Meeting and not later than the close of business on the 90th day prior to the 2025 Annual Meeting and the 10th day following the day on which public disclosure of the date of such meeting is first made by the Company. SEC rules permit management to vote proxies in its discretion in certain cases if the stockholder does not comply with this deadline and, in certain other cases, notwithstanding the stockholder’s compliance with this deadline. Stockholders are advised to review our Bylaws which also specify requirements as to the form and content of a stockholder's notice. In addition to satisfying the foregoing advance notice requirements, to comply with the universal proxy rules under the Exchange Act, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must follow the requirements set forth in Rule 14a-19 as promulgated under the Exchange Act.

33


We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.
