ANNUAL MEETING INFORMATION

Our board of directors is soliciting your proxy for the 2025 Annual Meeting of Stockholders (the Annual Meeting) of Biodesix, Inc. (Biodesix, the Company, we, us or our) and at any adjournment, continuation or postponement of the meeting for the purposes described in this proxy statement and the accompanying Notice of 2025 Annual Meeting of Stockholders. The Annual Meeting will take place virtually on May 20, 2025 at 1:00 p.m. Mountain Time. You must register to attend the meeting online and/or participate at www.proxydocs.com/BDSX using the control number on your proxy card or notice. You will receive an email one hour prior to the meeting containing a link which will connect you to the meeting portal. If you held shares of our Common Stock as of the close of business on March 24, 2025, you will be able to vote on the proposals described in this proxy statement and submit questions online through the virtual meeting platform during the Annual Meeting. On or about April 28, 2025, we will be mailing a copy of our Annual Report on Form 10-K for the year ended December 31, 2024 (the 2024 Annual Report), this Proxy Statement and the proxy card (together, the Proxy Materials). The documents will be available at www.proxydocs.com/BDSX.The proxy card will also include information on how to vote online or by telephone or by returning your proxy card by mail.

Who can vote?

If you were a stockholder of record as of the close of business on March 24, 2025 (the record date), you are entitled to vote your shares at the Annual Meeting. As of the record date, 146,443,291 shares of our Common Stock were issued and outstanding. Each share of our Common Stock is entitled to one vote on each matter properly brought before to the meeting.

What am I voting on?

You are being asked to vote on four proposals:

| ● | Proposal One: To elect the two Class II directors named in this proxy statement to hold office until the 2028 annual meeting of stockholders;

| ● | Proposal Two: To ratify the appointment of KPMG LLP as our independent registered public accounting firm for 2025;

| ● | Proposal Three: To approve an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the Company’s Common Stock at a ratio ranging from any whole number between 1-for-2 and 1-for-20, inclusive, as determined by our board of directors in its discretion, subject to our board of directors’ authority to abandon such amendments; and

| ● | Proposal Four: To approve the Company’s Amended and Restated Employee Stock Purchase Plan to increase the available shares of the Company’s Common Stock under the plan by 1,451,500 and to increase the maximum number of shares of the Company’s Common Stock that may be provided as the result of the plan’s annual automatic increase to 3,000,000.

2025 Proxy Statement |  | 1 |  |

How does the board of directors recommend that I vote on each proposal?

The board of directors recommends that our stockholders vote:

| ● | “For” the election of the two Class II directors named in this proxy statement to hold office until the 2028 annual meeting of stockholders;

| ● | “For” the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for 2025;

| ● | “For” the approval of an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the Company’s Common Stock; and

| ● | “For” the approval of the Company’s Amended and Restated Employee Stock Purchase Plan.

What if another matter is properly brought before the meeting?

The board of directors is not aware of any other matters that will be presented for consideration at the Annual Meeting. However, if any other matters are properly brought before the Annual Meeting, the persons named in the accompanying proxy intend to vote on those matters in accordance with their best judgment.

How do I vote?

The procedures for voting depend on whether your shares are registered in your name or are held by a bank, broker or other nominee. You may also vote your shares electronically during a designated portion of the virtual Annual Meeting after your successful registration at www.proxydocs.com/BDSX. Whether or not you plan to attend the Annual Meeting, we encourage you to vote and submit your proxy in advance of the meeting by one of the methods described below.

| ● | Stockholders of Record: Shares Registered in Your Name

Vote by Proxy in Advance of the Annual Meeting: If, on the record date, your shares were registered directly in your name with Biodesix’s transfer agent, Computershare Trust Company, N.A., then you are a “stockholder of record.” As a stockholder of record, you may vote by proxy in advance of the Annual Meeting in three ways:

Vote by Internet Go to http://www.proxypush.com/ BDSX to complete an electronic proxy card. You will be asked to provide the Company number and control number from your proxy card. Your vote must be received prior to the meeting start time to be counted. |  | Vote by telephone Dial toll-free 1-866-291-6774 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the Company number and control number from your proxy card. Your vote must be received prior to the meeting start time to be counted. |  | Vote by mail Complete, sign and date the proxy card you received as part of the Proxy Materials, and return it promptly in the envelope provided. If your signed proxy card is received prior to the meeting date, we will vote your shares as you direct.

2025 Proxy Statement |  | 2 |  |

| ● | Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Nominee

If, on the record date, your shares were held not in your name, but in an account with a broker, bank or other nominee as custodian on your behalf, then you are considered the “beneficial owner” of shares held in “street name.” The Proxy Materials are being forwarded to you by that broker, bank or other nominee who is considered the stockholder of record of those shares for purposes of voting at the Annual Meeting. As the beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote your shares by following the instructions for voting set forth on that organization’s voting instruction card.

What is the effect of giving a proxy? What if I return a proxy card or otherwise vote but do not make specific choices?

Proxies are solicited by and on behalf of the board of directors. Robin Harper Cowie (our Chief Financial Officer, Secretary and Treasurer) and Christopher C. Vazquez (our Chief Accounting Officer) have been designated as proxy holders by the board of directors. If you properly grant your proxy, your shares will be voted as you instruct. If you return a signed proxy card or otherwise vote without marking specific voting selections, your shares will be voted as the board of directors recommends: “For” the election of two Class II directors (Proposal One); “For” the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for 2025 (Proposal Two); “For” the approval of the amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the Company’s Common Stock (Proposal Three); “For” the approval of the Company’s Amended and Restated Employee Stock Purchase Plan (Proposal Four); and in accordance with the best judgment of your proxy holder for any other matters properly brought before the meeting, if any.

Can I change my vote or revoke my proxy?

Yes. If you are a stockholder of record, you can change your vote or revoke your proxy and voting instructions at any time prior to the vote at the annual meeting. To do so:

● Submit a new proxy card or voting instructions to the independent tabulator, Mediant Communications Inc. (Mediant), by mail, telephone or through the Internet by the closing of the polls at the annual meeting.

● Attend the virtual Annual Meeting and vote electronically during the meeting. Simply attending the meeting will not, by itself, revoke your proxy.

If you are the beneficial owner of shares held in street name, you should follow the instructions provided by your broker, bank or other nominee to revoke previously submitted voting instructions.

What are broker non-votes?

Brokers, banks or other nominees holding shares on behalf of a beneficial owner may vote those shares in their discretion on certain “routine” matters even if they do not receive timely voting instructions from the beneficial owner. With respect to “non-routine” matters, the broker, bank or other nominee is not permitted to vote shares for a beneficial owner without timely received voting instructions. The routine matters to be presented at the Annual Meeting are the proposal to ratify the appointment of KPMG LLP as our independent registered public accounting firm for 2025 (Proposal Two) and approval of an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the Company’s Common Stock (Proposal Three). The election of two Class II directors (Proposal One) and the approval of the Company’s Amended and Restated Employee Stock Purchase Plan (Proposal Four) are non-routine matters.

2025 Proxy Statement |  | 3 |  |

A broker non-vote occurs when a broker, bank or other nominee does not vote on a non-routine matter because the beneficial owner of such shares has not provided voting instructions with regard to such matter. If a broker, bank or other nominee exercises discretionary voting authority on Proposal Two and Proposal Three, such shares will be considered present at the Annual Meeting for quorum purposes and broker non-votes will occur as to Proposal One and Proposal Four and any other non-routine matters that are properly presented at the Annual Meeting. Broker non-votes will have no impact on the voting results.

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. A quorum will be present if the holders of at least a majority of the outstanding shares of our Common Stock entitled to vote are present at the Annual Meeting online or represented by proxy. On the record date, there were 146,443,291 shares of our Common Stock outstanding and entitled to vote. Therefore, the holders of 73,221,646 shares must be present online or represented by proxy at the Annual Meeting to have a quorum. For purposes of determining the presence of a quorum, abstentions, withheld votes and broker non-votes are counted. If there is no quorum, the holders of a majority of shares present or represented by proxy at the Annual Meeting may adjourn the meeting to a later date.

2025 Proxy Statement |  | 4 |  |

What vote is required for the approval of each proposal? What effect do “withhold” votes, abstentions and broker non-votes have on the proposals?

The following chart summarizes the proposals to be considered at the Annual Meeting, the vote required for approval of each proposal, and the manner in which votes will be counted:

Proposal |  | Voting Options |  | Vote Required to Adopt the Proposal |  | Effect of “Withheld” Votes or Abstentions |  | Effect of “Broker Non-Votes”
Proposal One: Election of the two Class II directors named in this proxy statement |  | For or Withhold on each nominee |  | Plurality of the votes cast. This means that the two nominees receiving the highest number of “For” votes (from the holders of votes of shares present or represented by proxy and entitled to vote on the election of directors) will be elected as Class II directors. |  | “Withheld” votes have no effect; only “For” votes affect the outcome of the election. |  | Brokers do not have discretion to vote. Broker non-votes will have no effect; only “For” votes affect the outcome of the election.
Proposal Two: Ratification of appointment of KPMG LLP as our independent registered public accounting firm for the year ended December 31, 2025 |  | For, Against or Abstain |  | Affirmative vote of a majority of the shares present or represented by proxy and entitled to vote on the proposal. |  | Abstentions are considered shares present and entitled to vote, and therefore have the same impact as votes “Against” the proposal. |  | Brokers have discretion to vote. Therefore, we do not expect any broker non-votes.
Proposal Three: Approval of an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the Company’s Common Stock at a ratio ranging from any whole number between 1-for-2 and 1-for-20, inclusive, as determined by our board of directors in its discretion, subject to our board of directors’ authority to abandon such amendments |  | For, Against or Abstain |  | Affirmative vote of a majority of the shares present or represented by proxy and entitled to vote on the proposal. |  | Abstentions are considered shares present and entitled to vote, and therefore have the same impact as votes “Against” the proposal. |  | Brokers have discretion to vote. Therefore, we do not expect any broker non-votes.
Proposal Four: Approval of the Company’s Amended and Restated Employee Stock Purchase Plan to increase the available shares of the Company’s Common Stock under the plan by 1,451,500 and to increase the maximum number of shares of the Company’s Common Stock that may be provided as the result of the plan’s annual automatic increase to 3,000,000 |  | For, Against or Abstain |  | Affirmative vote of a majority of the shares present or represented by proxy and entitled to vote on the proposal. |  | Abstentions are considered shares present and entitled to vote, and therefore have the same impact as votes “Against” the proposal. |  | Brokers do not have discretion to vote. Broker non-votes will have no effect; only “For” votes affect the outcome of the election.

Why were my Proxy Materials included in the same envelope as other people at my address? How may I obtain an additional copy of the Proxy Materials?

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, we deliver a single copy of our Proxy Materials to stockholders of record who share the same address, unless we have received contrary instructions from any stockholder at that address. This practice is designed to eliminate duplicate mailings, conserve natural resources and reduce our printing and mailing costs. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. If you share an address with another stockholder and receive only a single copy of our Proxy Materials, but would like to request a separate copy of these materials, please contact our mailing agent, Mediant, by calling 1-866-648-8133 or e-mailing paper@investorelections.com and an additional copy of the materials will be promptly delivered to you. Similarly, if you receive multiple copies of the Proxy Materials, but would prefer to receive a single copy in the future, you may also contact Mediant at the above telephone number or address. Beneficial owners should contact their broker, bank or other nominee to request information about householding procedures.

BOARD AND CORPORATE GOVERNANCE MATTERS

Proposal One: Election of Directors

General

The primary responsibilities of our board of directors are to provide oversight, strategic guidance, counseling and direction to our management. Our board of directors currently consists of nine directors and is divided into three classes of directors that serve staggered three-year terms, currently Class II, with a term expiring in 2025, Class III, with a term expiring in 2026 and Class I, with a term expiring in 2027. At the Annual Meeting, our stockholders will vote on the election of two Class II directors whose terms will expire at our 2028 annual meeting of stockholders. Each of our other current directors will continue to serve as a director until the election and qualification of his or her successor.

One current Class II member of our board of directors, Charles Watts, M.D., will not stand for reelection at the Annual Meeting. One current Class III member of our board of directors, Jack Schuler, will transition to the role of emeritus director at the Annual Meeting. As a result, the size of our board of directors will be reduced from nine (9) to seven (7) directors effective as of immediately prior to the closing of the polls at the Annual Meeting. The other two directors currently serving on our board of directors in Class II, the class whose term of office expires in 2025, have both been nominated by our board of directors, upon the recommendation of our nominating and corporate governance committee, to stand for election at the Annual Meeting. Lawrence T. Kennedy, Jr. has served on our board of directors since 2023. Matthew Strobeck, Ph.D. has served on our board of directors since 2012. Both of these two nominees have consented to being named as a nominee in this proxy statement and have agreed to serve, if elected, until our 2028 annual meeting of stockholders and until the election and qualification of his successor.

For more information about each of the director nominees and continuing directors, including information regarding the experience, qualifications, attributes and skills that led to the conclusion that each director should serve as a member of the board of directors, please refer to the section below entitled “Overview of Our Nominees and Continuing Directors.”

Vote Required: |  | Directors are elected by a plurality of the votes cast by our stockholders at the Annual Meeting. This means that the two nominees receiving the highest number of affirmative votes (from the holders of votes of shares present or represented by proxy and entitled to vote on the election of directors) will be elected. Broker non-votes and “Withheld” votes will have no effect.
Board Recommendation: |  | OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE ELECTION OF EACH OF THE TWO CLASS II DIRECTOR NOMINEES NAMED ABOVE. |  |

Board Composition

In accordance with our amended and restated certificate of incorporation, our board of directors is divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our directors are divided among the three classes as follows:

| • |  | the Class II directors are Matthew Strobeck, Ph.D. and Lawrence T. Kennedy Jr., and their terms will expire at the Annual Meeting;

| • |  | the Class III directors are Jean Franchi and Hany Massarany, and their terms expire at the 2026 annual meeting of stockholders; and

| • |  | the Class I directors are Jon Faiz Kayyem, Ph.D., John Patience and Scott Hutton, and their terms will expire at the 2027 annual meeting of stockholders.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that the authorized number of directors may be changed only by resolution of the board of directors. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one third of the directors. Each director’s term continues until the election and qualification of his or her successor, or, if sooner, his or her death, resignation or removal.

Director Independence

Under the listing requirements and rules of Nasdaq Stock Market (Nasdaq), independent directors must comprise a majority of our board of directors as a listed company within one year of the closing of our initial public offering.

Our board of directors has undertaken a review of its composition, the composition of its committees and the independence of each director. 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 Ms. Franchi, Messrs. Massarany, Patience and Kennedy and Drs. Kayyem and Strobeck 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 “independent” as that term is defined under the applicable listing requirements and rules of Nasdaq. In making this determination, 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 Leadership Structure

Our corporate governance guidelines provide our board of directors with flexibility to combine or separate the positions of Chairman of the board of directors and the Chief Executive Officer and/or the implementation of a lead director in accordance with its determination that utilizing one or the other structure

2025 Proxy Statement |  | 12 |  |

would be in the best interests of the Company. Mr. Patience currently serves as the independent Chairman of our board of directors. Our board of directors believes that separating these positions reinforces the independence of our board of directors from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of our board of directors as a whole.

Role of our Board of Directors in Risk Oversight

Our board of directors is responsible for overseeing the overall risk management process at Biodesix. The day-to-day responsibility for managing risks and exposures resides with our executive management team while our board committees and our board of directors as a whole participate in the oversight process. The risk oversight process includes receiving regular reports from committees and management to enable our board of directors to understand management’s risk assessment and mitigation processes, which includes areas of potential material risk, including long-term strategic and operational planning, strategic biopharmaceutical partnerships, executive development and evaluation, regulatory and legal compliance, information technology (including cybersecurity), financial reporting and internal controls and reputational risk. Our board of directors focuses on the overall risks affecting us, and each of its standing committees has been delegated responsibility for oversight of specific risks that fall within its areas of responsibility. For example:

| • |  | Our audit committee is responsible for overseeing our major financial, legal and regulatory risk exposures, which spans a variety of areas including litigation, regulatory compliance, financial reporting, insurance and cybersecurity. Our audit committee also oversees the steps management has taken to monitor and control such exposures, including guidelines and policies for assessing and managing risk and related compliance efforts.

| • |  | Our 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, including monitoring the effectiveness of our corporate governance guidelines and cybersecurity risk profile and other policies such as our code of conduct and overseeing our environmental and sustainability efforts and progress.

| • |  | Our compensation committee regularly assesses risks arising from our compensation plans, policies and programs, including whether any such plans encourage excessive or inappropriate risk-taking.

While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the full board of directors is regularly informed through committee reports about such risks.

Meetings of our Board of Directors

Our board of directors held five meetings during 2024. Each incumbent director attended at least 75% of the aggregate total number of meetings of the board of directors and the committees on which he or she served held during the portion of 2024 for which he or she was a director or committee member. We encourage our directors to attend our annual meetings of stockholders. Eight directors, including our Chief Executive Officer, Mr. Hutton, attended our 2024 annual meeting of stockholders.

Committees of our Board of Directors

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee. Our board of directors may establish other committees to facilitate the management of our business. The composition and functions of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by our board of directors. The charter of each committee is available on our corporate website at www.biodesix.com in the Investors section

Director Nomination Process

Selection and Nomination Process

Our board of directors is responsible for nominating members for election to our board of directors by our stockholders at our annual meetings of stockholders. Whenever a vacancy occurs on our board of directors, whether due to a newly created director position or the death, resignation, removal or retirement of an existing director, our board of directors is authorized to select a person to fill the vacancy to serve as a director until the annual meeting of stockholders at which the director’s term expires and until the election and qualification of his or her successor or, if sooner, his or her death, resignation or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors.

Criteria for Board Membership

The board of directors and the nominating and corporate governance committee will determine the appropriate characteristics, skills and experience for the board of directors as a whole and for its individual members. The board of directors and the nominating and corporate governance committee will consider the minimum general criteria set forth below, and may add any specific additional criteria with respect to specific searches, in selecting candidates and existing directors for service on the board of directors. An acceptable candidate may not fully satisfy all of the criteria, but is expected to satisfy nearly all of them. While the nominating and corporate governance committee does not have a formal policy in this regard, the diversity of the board of the directors is a consideration in evaluating candidates for director positions, among others.

The board of directors and the nominating and corporate governance committee believe that candidates for director should have certain minimum qualifications, including being able to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. In considering candidates, the board of directors and the nominating and corporate governance committee intend to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of our stockholders.

The board of directors and the nominating and corporate governance committee review candidates for director nomination in the context of the current composition of the board of directors, the operating

2025 Proxy Statement |  | 16 |  |

requirements of the Company and the long-term interests of our stockholders. In conducting this assessment, the board of directors and the nominating and corporate governance committee consider diversity, age, skills, and such other factors as it deems appropriate given the current needs of the board of directors and the Company to maintain a balance of knowledge, experience and capability. In the case of incumbent directors whose terms of office are set to expire, the board of directors and the nominating and corporate governance committee review such directors’ overall service to the Company during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, the board of directors and the nominating and corporate governance committee also determine whether the nominee must be independent for purposes of any stock exchange on which any of the Company’s capital stock is listed.

Stockholder Recommendations and Nominations

Stockholders who wish to recommend candidates may contact the nominating and corporate governance committee in the manner described below under “Board and Corporate Governance Matters—Stockholder Communications with our Board of Directors.” Stockholder nominations must be made according to the procedures required under our bylaws and described in this proxy statement under the heading “Additional Information—Stockholder Proposals and Nominations for Next Year’s Annual Meeting of Stockholders.” Stockholder-recommended candidates and stockholder nominees whose nominations comply with these procedures will be evaluated by our nominating and corporate governance committee in the same manner as other nominees.

DIRECTOR COMPENSATION

Non-Employee Director Compensation Policy

The following summarizes our non-employee director compensation policy, as amended in the first quarter of 2024. Our employee director receives no additional compensation for service on our board of directors.

● Annual Retainers:

| – | Each non-employee director is entitled to receive annual retainers in the amount summarized in the table below.

Position |  | Annual Retainer |
Board Member |  | $ | 40,000 |
Chair of the Board of Directors |  | $ | 0 |
Committee Chairs: |  |  |  |
Audit |  | $ | 20,000 |
Compensation |  | $ | 15,000 |
Nominating and Corporate Governance |  | $ | 10,000 |
Committee Members: |  |  |  |
Audit |  | $ | 0 |
Compensation |  | $ | 0 |
Nominating and Corporate Governance |  | $ | 0 |

| – | For service from April 1, 2024 to March 31, 2025, non-employee directors could elect to receive annual retainers in cash or RSUs, or a mixture of cash and RSUs (with 25%, 50% or 75% of such annual retainers paid in RSUs). Annual retainers paid in cash would be paid in equal quarterly installments, in arrears following the end of each quarter in which the service was performed. Equity grants made in respect of annual retainers were granted as of the date of our 2024 annual meeting of stockholders, were valued based on the average price of our Common Stock over a 90-day period preceding the date of grant, and vested on March 31, 2025. If a non-employee director became a director after April 1, 2024, his or her annual retainers were pro-rated based on the period of the non-employee director’s service on our board of directors during the year.

| – | For service from April 1, 2024 to March 31, 2025, all of our non-employee directors elected to receive their annual retainers with respect to service on our board of directors or any of its committees in the form of RSUs. The average closing price of our Common Stock for the 90-day period beginning on February 21, 2024 and ending on May 20, 2024 was $1.42. Based on this price, it was determined that each non-employee director was entitled to a grant of 28,161 RSUs. In addition, the Audit Committee Chair, Compensation Committee Chair, and Nominating and Corporate Governance Committee Chair were entitled to a grant of 14,080 RSUs, 10,560, RSUs, and 7,040 RSUs, respectively.

● Equity Compensation:

| – | Upon appointment to our board of directors, each non-employee director is entitled to receive an initial stock option grant having a Black Scholes value of $187,500, determined as of the date of grant based on the average price of our Common Stock over a 90-day period preceding the date of grant, with 40% vesting on the two-year anniversary of the grant date and the remainder vesting ratably on each subsequent monthly anniversary of the grant date for 36 months, subject to such director’s continuous service through each applicable vesting date. The Company limits the number of shares of Common Stock that may be subject to the initial stock option grant to 0.075% of the Company’s outstanding shares of Common Stock as of the immediately preceding January 1, which may result in a newly appointed non-employee director receiving an initial stock option grant having a Black Scholes value that is less than $187,500.

2025 Proxy Statement |  | 22 |  |

| – | Upon appointment to our board of directors, each non-employee director is also entitled to receive an initial RSU grant valued at $187,500 as of the date of grant based on the average price of our Common Stock over a 90-day period preceding the date of grant, which will vest on the one-year anniversary of the grant date subject to such director’s continuous service through such date. The Company limits the number of shares of Common Stock that may be subject to the initial RSU grant to 0.0375% of the Company’s outstanding shares of Common Stock as of the immediately preceding January 1, which may result in a newly appointed non-employee director receiving an initial RSU grant having a value that is less than $187,500.

| – | For service from April 1, 2024 to March 31, 2025, each non-employee director continuing his or her service on our board of directors following the annual meeting of stockholders was entitled to receive an annual stock option grant having a Black Scholes value of $96,250 and an annual RSU grant valued at $96,250, in each case determined as of the date of the 2024 annual meeting of stockholders, based on the average price of our Common Stock over the preceding 90 days, which vested on March 31, 2025, subject to such director’s continuous service through such date. The Company limits the number of shares of Common Stock that may be subject to an annual stock option grant or an annual RSU grant to 0.0385% and 0.01925%, respectively, of the Company’s outstanding shares of Common Stock as of the immediately preceding January 1. The average closing price of our Common Stock for the 90-day period beginning on February 21, 2024 and ending on May 20, 2024 was $1.42. Based on this price, each non-employee director would have been granted an option to purchase 103,354 shares of the Company’s Common Stock and 67,762 RSUs on May 21, 2024. However, as a result of the grant limitations described above, each non-employee director was instead granted an option to purchase 37,050 shares of the Company’s Common Stock, having a Black Scholes value as of the date of grant of $1.06, and 18,525 RSUs with a grant date value of $1.42.

| – | Notwithstanding the vesting schedules described above, each non-employee director who remains in continuous service until a change of control (as defined in our 2020 Incentive Plan) will become fully vested in all then-outstanding equity awards. In addition, annual equity grants and equity grants in respect of annual retainers that were granted during 2024 will vest on a prorated basis in the event a director resigns or otherwise experiences a termination of service other than for cause.

● Expense Reimbursement: Our non-employee directors are also reimbursed for their reasonable out-of-pocket travel expenses to cover in-person attendance at and participation in board and committee meetings.

The non-employee director compensation policy was further amended on October 30, 2024, effective as of April 1, 2025, to provide that non-employee directors will receive annual retainers in the form of RSUs that vest in equal quarterly installments and to provide that annual equity grants will also vest in equal quarterly installments, beginning with 2025 grants.

Director Deferred Compensation Plan

On December 21, 2021, our compensation committee adopted the 2021 Non-Employee Director Deferred Compensation Plan (the Director Deferred Compensation Plan), an unfunded, non-qualified deferred compensation plan that allows our non-employee directors to defer RSU awards that they receive.

Any RSU deferred will be credited as deferred units to the non-employee director’s account as of the date on which it vests. Each deferred unit is credited with dividend equivalents equal to the dividends paid, if any, on our Common Stock, which are deemed reinvested in additional deferred units on the dividend payment date. Deferred units will be appropriately adjusted in the event of any change in our Common Stock through merger, consolidation, or otherwise; a stock dividend; or a stock split, combination or other change in our Common Stock.

2025 Proxy Statement |  | 23 |  |

Payments will be made in shares of our Common Stock equal to the number of deferred units credited to the director’s account, with a cash payment for any fractional deferred unit. A director may elect to receive deferred amounts in a lump sum within 90 days after either his or her separation from service or, alternatively the later of his or her separation from service or January 1 of a calendar year elected by the director which may not be more than 15 years after the calendar year in which the director’s initial deferral election under the Director Deferred Compensation Plan was made. Within 90 days following a non-employee director’s death, a lump sum equal to the then-remaining balance in his or her account will be made to his or her beneficiary. Within 10 business days after a change in control (as defined in our 2020 Incentive Plan) and to the extent permitted by federal tax law, each non-employee director (or former non-employee director) will receive a cash lump sum payment equal to the number of deferred units credited to his or her account on the date of the change in control, multiplied by the fair market value of one share of our Common Stock on such date. If payment within 10 business days following a change in control is not permitted by federal tax laws, then payment will be made at the time and in the form that payment would have been made if a change in control had not occurred.

2024 Director Compensation Table

The following table sets forth information for the fiscal year ended December 31, 2024 regarding the compensation awarded to, earned by or paid to our non-employee directors. The compensation received by our non-employee directors in respect of annual retainers for 2024 service was in the form of RSU awards and the compensation received by our non-employee directors in respect of annual equity grants was a mixture of stock option and RSU awards. Each of Messrs. Schuler, Patience and Kennedy, and Drs. Kayyem and Watts received grants for a total of 152,075 RSUs and stock options in respect of 37,050 shares of our Common Stock.

EXECUTIVE COMPENSATION

The following is a discussion of compensation arrangements of our named executive officers. This discussion contains forward-looking statements that are based on our current plans, considerations, expectations, and determinations regarding future compensation programs. Actual compensation programs that we adopt may differ materially from currently planned programs as summarized in this discussion. As an “emerging growth company” as defined in the JOBS Act, we are not required to include a Compensation Discussion and Analysis section and have elected to comply with the scaled back disclosure requirements applicable to emerging growth companies. In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of either the compensation of our named executive officers or the frequency with which such votes must be conducted.

Overview

This section provides a discussion of the compensation paid or awarded to our Chief Executive Officer and our two other most highly compensated executive officers as of December 31, 2024. We refer to these individuals as our “named executive officers.” For 2024, our named executive officers were:

| • |  | Scott Hutton, President and Chief Executive Officer;

| • |  | Robin Harper Cowie, Chief Financial Officer, Secretary and Treasurer; and

| • |  | Kieran O’Kane, Chief Commercial Officer.

Our executive compensation program is intended to align executive compensation with our performance objectives and business strategy and to enable us to attract, motivate, retain and reward executive officers who operate in a highly competitive and technologically challenging environment and whose contributions are critical to our long-term success. The compensation paid or awarded to our executive officers is generally based on the assessment of each individual’s performance compared against the business objectives established for the fiscal year as well as our historical compensation practices. The compensation paid to newly hired executive officers is primarily determined based on the negotiations of the parties as well as our historical compensation practices, and we seek fairness in total compensation paid to our executive officers. As a result, we benchmark executive compensation against external and internal comparisons and look at the relationship between team member roles in the organization to determine appropriate compensation. For the year ended December 31, 2024, the material elements of our executive compensation program were base salary, annual cash bonus and equity awards in the form of RSUs and stock options.

Performance-based, at risk and variable compensation in the form of annual cash bonuses and equity-based compensation is a significant portion of the overall compensation paid to each named executive officer. Our annual cash bonuses are earned or vest only upon the achievement of certain performance metrics. In addition, the value received from RSUs and stock options depends on our stock price.

We expect that our executive compensation program will continue to evolve over the coming years, while still supporting our overall business and compensation objectives. The compensation committee of our board of directors oversees our executive compensation program. In addition, during the year ended December 31, 2024, the compensation committee utilized our independent executive compensation consultant to advise us on the elements of our executive compensation program.

2025 Proxy Statement |  | 26 |  |

Compensation of Named Executive Officers

Base Salary

Base salaries are intended to provide a level of compensation sufficient to attract and retain an effective management team, when considered in combination with the other components of our executive compensation program. The relative levels of base salary for our named executive officers are designed to reflect each executive officer’s scope of responsibility and accountability to us. Please see the “Salary” column in the Summary Compensation Table for the base salary amounts received by each named executive officer during the years ended December 31, 2023 and December 31, 2024.

As of January 1, 2024, Mr. Hutton’s annual base salary was $515,000, Ms. Harper Cowie’s annual base salary was $355,000, and Mr. O’Kane’s annual base salary was $335,000. The compensation committee retained an independent executive compensation consultant and after review of external market data and consideration of individual factors including, but not limited to, performance and scope of role, determined to increase base salaries for the named executive officers. As of March 1, 2024, Mr. Hutton’s annual base salary was increased to $608,000, and each of Ms. Harper Cowie’s and Mr. O’Kane’s annual base salary was increased to $419,000. As of March 1, 2025, Mr. Hutton’s annual base salary was increased to $652,500, Ms. Harper Cowie’s annual base salary was increased to $449,500 and Mr. O’Kane’s annual base salary was increased to $449,500.

Annual Cash Bonuses

We provide our senior leadership team with short-term incentive compensation through an annual cash bonus program. Annual bonus compensation holds executives accountable, rewards the executives based on actual business results and helps create a “pay for performance” culture. Our annual cash bonus program provides cash incentive award opportunities based on the achievement of performance goals approved by our compensation committee at the beginning of each fiscal year.

Generally, our compensation committee establishes a Company-based performance metric as a threshold vesting criterion for any payouts for a particular annual bonus period. For 2024, individual performance goals did not factor into determining payouts for the annual bonus period.

For 2024, the compensation committee determined that the Company’s short-term incentive compensation would be based on the achievement of three financial objectives, (i) total revenue determined in accordance with U.S. GAAP, (ii) lung diagnostic gross margin percentage and (iii) total operating expense (excluding certain non-cash expenses). Actual results were measured at year end against targeted outcomes. Mr. Hutton’s, Ms. Harper Cowie’s and Mr. O’Kane’s 2024 bonus targets as a percentage of annual base salary were 100%, 50% and 60%, respectively. Based on our 2024 performance, our compensation committee determined, and our board of directors approved, a corporate funding percentage under our annual cash bonus program equal to approximately 75.4% of the target bonus opportunity.

Under the Company’s 2021 Senior Management Bonus to Equity Plan, eligible executives, including each of our named executive officers, were permitted to elect to receive 25%, 50%, 75% or 100% of the annual bonus earned in the form of a bonus-to-options award, subject to an individual cap equal to the executive’s target annual bonus or any maximum dollar amount or percentage approved by the Company or the executive for such year. The maximum percentage that applied for 2024 was 50%. The bonus-to-options awards, if any, are fully vested on the grant date and have an exercise price equal to the fair market value of our Common Stock on the grant date. The program reflects our commitment to a “pay for performance” philosophy and further aligns our executive compensation program with the long-term interests of our stockholders because an executive who participates foregoes a portion of his or her annual cash bonus in exchange for an option award that will be valuable only if the stock price increases.

2025 Proxy Statement |  | 27 |  |

Pursuant to elections made in 2023, each named executive officer received a portion of their respective annual bonuses earned for 2024 in the form of a bonus-to-options award instead of in cash. For annual bonuses earned in 2024, the number of shares of the Company’s Common Stock subject to each bonus-to-options award granted in 2024 was determined by multiplying the cash value of the bonus that was elected to be received in the form of an option award by three, and then dividing the product of that calculation by $1.57 (the Company’s average stock price during 2024, calculated based on the daily closing price of our publicly traded Common Stock). Accordingly, each of Mr. Hutton, Ms. Harper Cowie and Mr. O’Kane received a payout under the 2024 annual cash bonus program in cash and/or a bonus-to-options award, as illustrated below:

2024 |
Name |  | Incentive Cash Payout |  |  | Shares Subject to Bonus- to-Option Award |
Scott Hutton |  | $ | 223,604 |  |  | $ | 425,929 |
Robin Harper Cowie |  | $ | 115,597 |  |  | $ | 73,398 |
Kieran O’Kane |  | $ | 137,522 |  |  | $ | 87,319 |

Equity Awards
In the year ended December 31, 2024, the compensation committee awarded Mr. Hutton, Ms. Harper Cowie and Mr. O’Kane, 210,625 RSUs, 64,381 RSUs and 64,381 RSUs, respectively, which vest ratably on an annual basis for four years from the vesting commencement date, subject to continued service through the applicable vesting date. In addition, the compensation committee awarded Mr. Hutton, Ms. Harper Cowie and Mr. O’Kane, stock options in respect of 421,250, 128,761 and 128,761 shares of our Common Stock, respectively, which vest ratably on a monthly basis for four years from the vesting commencement date, subject to continued service through the applicable vesting date.
For 2025, the compensation committee has determined to continue to award a blend of stock options and RSUs to each of our named executive officers.

In September 2020, the board of directors amended these time-vested options such that 21/60 of the time-vested options vest on the date that is 21 months after the vesting commencement date, with the remaining balance vesting in a series of 39 successive equal monthly installments measured from such date, subject to the award recipient’s continued employment through the applicable vesting date.

| (3) | These time-vested RSUs vest in a series of four successive equal annual installments measured from the vesting commencement date, subject to the award recipient’s continued employment through the applicable vesting date.

| (4) | In the year ended December 31, 2019, the board of directors awarded Mr. Hutton and Ms. Harper Cowie performance-vested options representing the right to purchase 25,269 and 17,688 shares of our Common Stock, respectively. One third of these performance-vested options were eligible to vest after each of the first, second and third anniversaries of the vesting commencement date, subject to the Company’s achievement of recognized revenue of at least $31 million, $67 million and $134 million for the years ended December 31, 2019, 2020 and 2021, respectively. The board of directors had sole discretion to determine if the performance hurdles are met and to determine the vesting date, and shall make such determinations within 90 days after the end of the applicable fiscal year. For the 2019 tranche, the board of directors determined that the performance hurdle was not met. As a result, one third of each of Mr. Hutton’s and Ms. Harper Cowie’s awards were cancelled, and two thirds of each of Mr. Hutton’s and Ms. Harper Cowie’s awards remained outstanding. In addition, in September 2020 and in light of the impact of the COVID-19 pandemic on the Company’s operations and other considerations, the board of directors amended the performance-vested options to adjust the performance hurdles for the 2020 tranche and the 2021 tranche to $28.6 million and $51.5 million, respectively. For each of the 2020 tranche and the 2021 tranche, the board of directors determined that the applicable performance hurdles were met and one third of each of Mr. Hutton’s and Ms. Harper Cowie’s performance-vested option award became fully vested and exercisable on January 1, 2021 and January 1, 2022, respectively.

The number of installments is equal to the number of months that were remaining the in the vesting schedule of the stock options that were tendered under the stock option exchange program as of immediately prior to the exchange.

| (9) | These stock options vest in a series of 48 successive, equal monthly installments measured from the vesting commencement date.

Policies and Practices Related to the Timing of Grants of Certain Equity Awards
The compensation committee and senior management monitor the Company’s equity grant practices to evaluate whether such policies comply with governing regulations and are consistent with good corporate practices. When making regular annual equity grants, the compensation committee’s practice is to approve them at its meeting in February of each year as part of the annual compensation review and after results for the preceding fiscal year become available. Because the compensation committee’s regular meeting schedule is determined in the prior fiscal year, the proximity of any awards to other significant corporate events is coincidental. In addition, the compensation committee may make grants at any time during the year it deems appropriate, including with respect to new hires or transitions. The Company does not schedule its equity grants in anticipation of the release of material non-public information nor does the Company time the release of material non-public information based on equity grant dates.
During 2024, no stock option grants were made to any of our named executive officers during any period beginning four business days before the filing or furnishing of a periodic report or current report and ending one business day after the filing or furnishing of any such report with the SEC.

Additional Matters

Executive Severance and Change in Control Agreements

On April 16, 2024, the Company approved a form of Executive Severance and Change in Control Agreement. On April 23, 2024, each of Mr. Hutton, Ms. Harper Cowie and Mr. O’Kane entered into an Executive Severance and Change in Control Agreement with the Company.

In the event an executive who is party to an Executive Severance and Change in Control Agreement experiences a termination of employment without cause (as defined in the Executive Severance and Change in Control Agreement), other than within three months prior to, or one year following, the consummation of a change in control (as defined in the Executive Severance and Change in Control Agreement), the executive will be entitled to receive:

| • |  | base salary continuation for a period of nine months or, in the case of the chief executive officer, 12 months;

| • |  | for the chief executive officer only, a lump sum cash payment equal to 100% of his or her target annual cash incentive for the year in which the qualifying termination of employment occurs; and

| • |  | Company-paid COBRA premium payments for the executive and his or her covered dependents for up to 12 months.

In the event the executive’s employment is terminated without cause or the executive resigns for good reason (as defined in the Executive Severance and Change in Control Agreement) within three months prior to, or one year following, the consummation of a change in control, the executive will be entitled to receive:

| • |  | a lump sum cash payment equal to 100%, or in the case of the chief executive officer, 150%, of his or her then-current annual base salary;

| • |  | a lump sum cash payment equal to 100%, or in the case of the chief executive officer, 150%, of his or her target annual cash incentive for the year in which the qualifying termination of employment occurs;

| • |  | a lump sum cash payment equal to 12 months, or in the case of the chief executive officer, 18 months, of COBRA premium payments for the executive and his or her covered dependents;

| • |  | accelerated vesting of all equity awards which vest based solely on the executive’s continued service with us; and

| • |  | for the chief executive officer and chief financial officer only, a lump sum cash payment of $15,000 to help defray legal fees, tax and accounting fees, executive outplacement services, and other costs associated with transitional matters.

The payment of severance benefits under the Executive Severance and Change in Control Agreements is subject to a general release of claims by the executive in favor of the Company and its affiliates.

We believe the severance benefits payable under the Executive Severance and Change in Control Agreements provide reasonable compensation in the form of severance pay and certain limited benefits to our executive officers in the event of a qualifying termination of employment to facilitate the transition to new employment. In addition, we believe that these benefits help maintain our executive officers’ continued focus on their assigned duties to maximize stockholder value in the event of a potential change in control transaction, and mitigate the risk of subsequent disputes or litigation. The terms and conditions of these agreements were approved by the compensation committee after an analysis of competitive market data in consultation with our independent executive compensation consultant.

401(k) Plan

The Company participates in a multiple employer tax-qualified 401(k) savings plan which allows participants to defer eligible compensation up to the maximum amount allowed under Internal Revenue Service (IRS) guidelines. The Company did not make any discretionary or employer matching contributions under the plan during 2024.

Clawback Policy

During the year ended December 31, 2023, the Company adopted a Dodd-Frank Clawback Policy to comply with SEC and Nasdaq listing rules. Under that policy, the Company is required in certain situations to recoup incentive compensation paid or payable to certain current or former executive officers of the Company, including the named executive officers, in the event of an accounting restatement.

AUDIT MATTERS

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

Our audit committee has appointed KPMG LLP as our independent registered public accounting firm for the year ending December 31, 2025. Although stockholder ratification of the appointment of KPMG LLP is not required by our bylaws, other governing documents or the law, our board of directors considers the appointment of our independent registered public accounting firm to be an important matter of stockholder concern and is submitting the appointment of KPMG LLP for ratification by our stockholders as a matter of good corporate practice. If our stockholders fail to ratify the appointment, our audit committee will review its future selection of KPMG LLP as its independent registered public accounting firm. Even if the appointment is ratified, our audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and our stockholders.

Our board of directors considers the appointment of KPMG LLP as our independent registered public accounting firm for 2025 to be in the best interests of the Company and our stockholders. We expect representatives of KPMG LLP to attend the Annual Meeting. They will have an opportunity to make a statement if they wish and will be available to respond to appropriate questions from stockholders.

KPMG LLP has served as our independent registered public accounting firm since 2016.

APPROVAL OF AN AMENDMENT TO THE COMPANY’S AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO EFFECT A REVERSE STOCK SPLIT OF THE COMPANY’S COMMON STOCK

Proposal Three: Approval of an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the Company’s Common Stock at a ratio ranging from any whole number between 1-for-2 and 1-for-20, inclusive, as determined by our board of directors in its discretion, subject to our board of directors’ authority to abandon such amendments

General

The amendment proposal (the “Reverse Stock Split Proposal”), if approved, would not immediately cause a reverse stock split, but rather would grant authorization to our board of directors to determine whether or not to adopt an amendment to our amended and restated certificate of incorporation to effect a reverse stock split of our Common Stock (without reducing the number of authorized shares of our Common Stock) at a ratio ranging from any whole number between 1-for-2 and 1-for-20, inclusive (the “Split Ratio Range”), in the form set forth in Annex A to this Proxy Statement. Our board of directors has deemed advisable, approved and recommended that our stockholders adopt, and is hereby soliciting stockholder approval of, the proposed amendment to our amended and restated certificate of incorporation to effect a reverse stock split at a ratio within the Split Ratio Range, in the form set forth in Annex A to this Proxy Statement.

If we receive the required stockholder approval of this proposal, our board of directors will have the sole authority to elect, at any time prior to the one year anniversary of the Annual Meeting, whether or not to effect a reverse stock split. Even with stockholder approval of the Reverse Stock Split Proposal, our board of directors will not be obligated to pursue the reverse stock split. Rather, our board of directors will have the flexibility to decide whether or not a reverse stock split (and at what ratio within the Split Ratio Range) is in the best interests of the Company and its stockholders.

If approved by our stockholders and following such approval our board of directors determines that effecting a reverse stock split is in the best interests of the Company and our stockholders, the reverse stock split would become effective upon filing a certificate of amendment to our amended and restated certificate of incorporation with the Secretary of State of the State of Delaware. As filed, the certificate of amendment would state the number of outstanding shares to be combined into one share of our Common Stock, at the ratio approved by our board of directors within the Split Ratio Range. The amendment would not change the par value of our Common Stock and would not impact the total number of authorized shares of our Common Stock. Therefore, upon effectiveness of a reverse stock split, the number of shares of our Common Stock that are authorized and unissued will increase relative to the number of issued and outstanding shares of our Common Stock.

Under Section 242(c) of the Delaware General Corporation Law, our board of directors has reserved the right, notwithstanding our stockholders’ approval of the proposed amendment of the amended and restated certificate of incorporation at the Annual Meeting, to abandon the proposed amendment at any time (without further action by our stockholders) before the certificate of amendment with respect thereto is filed with the Secretary of State of the State of Delaware. Our board of directors may consider a variety of factors in determining whether or not to proceed with the proposed amendment of the amended and restated certificate of incorporation and the appropriate range within the Split Ratio Range for any such amendment, including overall

2025 Proxy Statement |  | 41 |  |

trends in the stock market, recent changes and anticipated trends in the per-share market price of our Common Stock, business developments and our actual and projected financial performance.

Purpose and Overview of the Reverse Stock Split

Our Common Stock is listed on The Nasdaq Global Market. Our primary objective in effectuating a reverse stock split would be to attempt to raise the per-share trading price of our Common Stock to continue our listing on The Nasdaq Global Market. To maintain listing, The Nasdaq Global Market requires, among other things, that our Common Stock maintain a minimum closing bid price of at least $1.00 per share. On April 16, 2025, the closing bid price for our Common Stock on The Nasdaq Global Market was $0.55 per share.

On March 24, 2025, we received a written deficiency notice from Nasdaq’s Listing Qualifications Staff notifying the Company that, for the last 30 consecutive trading days, beginning on February 7, 2025 and ending on March 21, 2025, the bid price for the Company’s Common Stock had closed below the $1.00 minimum bid price. In accordance with Nasdaq listing rules, we were provided an initial compliance period of 180 calendar days, or until September 22, 2025, for our Common Stock to regain compliance by having a closing price of at least $1.00 per share for at least ten consecutive trading days. If we do not regain compliance with the minimum bid price rule, Nasdaq will provide us written notice that our Common Stock may be transferred to The Nasdaq Capital Market, or ultimately delisted. Following a transfer to The Nasdaq Capital Market, we may be afforded a second compliance period, unless it does not appear to Nasdaq that it is possible for us to cure the deficiency. We may also request a hearing to remain on The Nasdaq Global Market.

Our board of directors is seeking stockholder approval for the authority to effectuate the reverse stock split as a means of increasing the share price of our Common Stock at or above $1.00 per share in order to avoid further action by Nasdaq, in the event we are not able to satisfy the minimum bid price requirement prior to the expiration of the 180-day compliance period, or any additional time we may become eligible for. We expect that the reverse stock split would increase the bid price per share of our Common Stock above the $1.00 per share minimum bid price, thereby satisfying this listing requirement. However, there can be no assurance that the reverse stock split would have that effect, initially or in the future, or that it would enable us to maintain the listing of our Common Stock on The Nasdaq Global Market.

Additionally, we believe that the low per-share market price of our Common Stock impairs its marketability to, and acceptance by, institutional investors and other members of the investing public and creates a negative impression of the Company. Theoretically, decreasing the number of shares of our Common Stock outstanding should not, by itself, affect the marketability of the shares, the type of investor who would be interested in acquiring them or our reputation in the financial community. In practice, however, many investors, brokerage firms and market makers consider low-priced stocks as unduly speculative in nature and, as a matter of policy, avoid investment and trading in such stocks. Moreover, the analysts at many brokerage firms do not monitor the trading activity or otherwise provide coverage of lower-priced stocks. The presence of these factors may be adversely affecting, and may continue to adversely affect, not only the price of our Common Stock but also its trading liquidity. In addition, these factors may affect our ability to raise additional capital through the sale of our Common Stock.

We also believe that a higher stock price could help us attract and retain employees and other service providers. We believe that some potential employees and service providers are less likely to work for or provide services to a company with a low stock price, regardless of the size of the Company’s market capitalization. If the reverse stock split successfully increases the per-share price of our Common Stock, we believe this increase would enhance our ability to attract and retain employees and service providers. Further, the reverse stock split will result in additional authorized and unissued shares becoming available for general corporate purposes as the board of directors may determine from time to time, including for use under its equity compensation plans.

We further believe that a higher stock price could help us improve relations with existing and potential new customers. We believe that some prospective customers may take a more cautious view of a company with a

2025 Proxy Statement |  | 42 |  |

low stock price, regardless of the size of the Company’s market capitalization, and may be less likely to use a product or service from such a company. If the reverse stock split successfully increases the per-share price of our Common Stock, we believe this increase would reduce the likelihood of a potential negative sentiment from both existing and potential customers.

We believe that the decrease in the number of shares of our outstanding Common Stock because of the reverse stock split, and the anticipated increase in the price per share, would possibly promote greater liquidity for our stockholders with respect to their shares. However, liquidity may be adversely affected by the reduced number of shares that would be outstanding if the reverse stock split is effected, particularly if the price per share of our Common Stock begins a declining trend after the reverse stock split is effectuated. The proposed reverse stock split is not intended to be an anti-takeover device.

There can be no assurance that the reverse stock split would achieve any of the desired results. There also can be no assurance that the price per share of our Common Stock immediately after the reverse stock split would increase proportionately with the reverse stock split, or that any increase would be sustained for any period of time.

If our stockholders do not approve the Reverse Stock Split Proposal and the price of our Common Stock does not otherwise close at $1.00 per share or more for at least ten consecutive trading days before September 22, 2025, it is possible that we would be subject to a delisting action by Nasdaq. We believe a reverse stock split is the most likely way for our Common Stock to reach the minimum bid price requirement of The Nasdaq Global Market, although effectuating the reverse stock split cannot guarantee that we would be in compliance with the minimum bid price requirement for even the minimum ten-day trading period required by The Nasdaq Global Market.

If our Common Stock were delisted from The Nasdaq Global Market, trading of our Common Stock would thereafter be conducted on the OTC Bulletin Board or the “pink sheets,” which are generally considered to be less efficient markets. As a result, investors may find it more difficult to dispose of, or to obtain accurate quotations as to the price of, our Common Stock. Many investors would likely not buy or sell our Common Stock due to difficulty in accessing OTC markets or policies preventing them from trading in securities not listed on a national exchange. To relist shares of our Common Stock on any one of Nasdaq’s three market tiers, we would be required to meet Nasdaq’s initial listing requirements, which are more stringent than the maintenance requirements.

If our Common Stock was delisted from The Nasdaq Global Market (or The Nasdaq Capital Market if we transferred tiers following an unsuccessful attempt to satisfy the minimum bid price requirement prior to the expiration of the initial 180-day compliance period) and the market price of our Common Stock was below $5.00 at such time, such stock would come within the definition of “penny stock” as defined in the Exchange Act and would be covered by Rule 15g-9 of the Exchange Act. Rule 15g-9 imposes additional sales practice requirements on broker-dealers who sell such securities that would make trading in our Common Stock more difficult and the market less efficient.

In evaluating whether to seek stockholder approval of the Reverse Stock Split Proposal, our board of directors took into consideration negative factors associated with reverse stock splits. These factors include: the negative perception of reverse stock splits that investors, analysts and other stock market participants may hold; the fact that the stock prices of some companies that have effected reverse stock splits have subsequently declined, sometimes significantly, following their reverse stock splits; the possible adverse effect on liquidity that a reduced number of outstanding shares could cause; and the costs associated with implementing a reverse stock split.

Even if our stockholders approve the Reverse Stock Split Proposal, our board of directors reserves the right not to effect the proposed amendment in its entirety if in our board of directors opinion it would not be in the best interests of the Company or our stockholders to effect a reverse stock split.

2025 Proxy Statement |  | 43 |  |

Risks Associated with the Reverse Stock Split

We cannot predict whether the reverse stock split, if completed, will increase the market price for our Common Stock. The history of similar stock split combinations for companies in like circumstances is varied. There is no assurance that:

| • |  | the market price per share of our Common Stock after the reverse stock split would rise in proportion to the reduction in the number of shares outstanding before the reverse stock split;

| • |  | the reverse stock split would result in a per-share price that would attract brokers and investors who do not trade in lower-priced stocks;

| • |  | the reverse stock split would result in a per-share price that would increase our ability to attract and retain employees and other service providers; or

| • |  | the reverse stock split would promote greater liquidity for our stockholders with respect to their shares.

In addition, the reverse stock split would reduce the number of outstanding shares of our Common Stock without reducing the number of shares of available but unissued Common Stock, increasing the number of authorized but unissued shares of Common Stock. Therefore, the number of shares of our Common Stock that are authorized and unissued will increase relative to the number of issued and outstanding shares of our Common Stock following the reverse stock split. The board of directors may authorize the issuance of the remaining authorized and unissued shares without further stockholder action for a variety of purposes, except as such stockholder approval may be required in particular cases by our amended and restated certificate of incorporation, applicable law or the rules of any stock exchange on which our securities may then be listed. The issuance of additional shares would be dilutive to our existing stockholders and may cause a decline in the trading price of our Common Stock. The issuance of authorized but unissued shares of Common Stock could be used to deter a potential takeover of us that may otherwise be beneficial to stockholders by diluting the shares held by a potential suitor or issuing shares to a stockholder that will vote in accordance with the board of directors’ desires. A takeover may be beneficial to independent stockholders because, among other reasons, a potential suitor may offer such stockholders a premium for their shares of stock compared to the then-existing market price. We do not have any plans or proposals to adopt provisions or enter into agreements that may have material anti-takeover consequences.

The market price of our Common Stock is based on our performance and other factors, some of which are unrelated to the number of shares outstanding. If the reverse stock split is effected and the market price of our Common Stock declines, the percentage decline as an absolute number and as a percentage of our overall market capitalization may be greater than would occur in the absence of a reverse stock split.

Principal Effects of the Reverse Stock Split on the Market for Our Common Stock

On April 16, 2025, the closing bid price for our Common Stock on The Nasdaq Global Market was $0.55 per share. By decreasing the number of shares of our Common Stock outstanding without altering the aggregate economic interest represented by the shares, we believe the market price would be increased. However, there can be no assurance that the market price of the Common Stock would rise to or maintain any particular level. In addition, the fewer number of shares of Common Stock that will be available to trade will possibly cause the trading market of our Common Stock to become less liquid, which could have an adverse effect on the price of our Common Stock.

Principal Effects of the Reverse Stock Split on Our Common Stock; No Fractional Shares

If our stockholders approve the Reverse Stock Split Proposal, and if our board of directors decides to effectuate a proposed amendment to effect a reverse stock split, the principal effect of the amendment would be to reduce the number of issued and outstanding shares of our Common Stock, depending on the Split Ratio Range set forth in such amendment, from 146,443,291 shares as of the Record Date to between approximately

2025 Proxy Statement |  | 44 |  |

73,221,645 shares and approximately 7,322,164 shares. If the reverse stock split is effectuated, the total number of shares of our Common Stock each stockholder holds would be reclassified automatically into the number of shares of our Common Stock equal to the number of shares of our Common Stock each stockholder held immediately prior to the reverse stock split divided by the ratio approved by the board of directors within the Split Ratio Range and set forth in the applicable amendment.

Effecting the reverse stock split will not change the total authorized number of shares of our Common Stock. However, the reduction in the issued and outstanding shares would provide more authorized shares available for future issuance. Other than the shares available for future issuance under our 2006 Incentive Plan, 2016 Incentive Plan, 2020 Incentive Plan, ESPP, 2011 Second Amended and Restated Bonus-to-Options Program, and 2015 Third Amended and Restated Bonus-to-Options Program (collectively, the “Plans”), we have no specific plan, commitment, arrangement, understanding or agreement, either oral or written, regarding the issuance of Common Stock subsequent to this proposed reverse stock split at this time. However, we have in the past conducted certain public and private offerings of our securities, and we may continue to require additional capital in the future to fund our operations. As a result, it is possible that we will seek to issue such additional shares of Common Stock in connection with any such capital raising activities, or any of the other activities described above. The board of directors does not intend to issue any Common Stock or securities convertible into Common Stock except on terms that the board of directors deems to be in the best interests of us and our stockholders.

The reverse stock split would affect all holders of our Common Stock uniformly and would not affect any stockholder’s percentage ownership interests, except to the extent that the reverse stock split results in such stockholder owning a fractional share. No fractional shares will be issued in connection with the reverse stock split. Stockholders who otherwise would be entitled to receive fractional shares because they hold a number of pre-split shares not evenly divisible by the number of pre-split shares for which each post-split share is to be exchanged, will be entitled to a cash payment in lieu thereof at a price equal to the fraction to which the stockholder would otherwise be entitled multiplied by the closing price of the Common Stock, as reported by Nasdaq, on the last trading day prior to the effective date of the split. The proceeds would be subject to certain taxes as discussed below. In addition, stockholders would not be entitled to receive interest for the period of time between the filing of the certificate of amendment to the amended and restated certificate of incorporation and the date a stockholder receives payment for the cashed-out fractional shares. The payment amount would be paid to the stockholder in accordance with the procedures outlined below.

After the reverse stock split, a stockholder would have no further interest in the Company with respect to such stockholder’s cashed-out fractional shares. A person otherwise entitled to a fractional interest would not have any voting, dividend or other rights except to receive payment as described above.

The reverse stock split may result in some stockholders owning “odd lots” of less than 100 shares of Common Stock. Odd lot shares may be more difficult to sell, and brokerage commissions and other costs of transactions in odd lots may be higher than the costs of transactions in “round lots” of even multiples of 100 shares.

After the effective date, our Common Stock would have a new CUSIP number, which is a number used to identify our equity securities. Stock certificates issued before the reverse stock split will reflect the older CUSIP number and should be returned to our transfer agent by following the procedures described below under “Effect on Registered Certificated Shares.”

Principal Effects of the Reverse Stock Split on Outstanding Equity

As of the Record Date, we had outstanding (a) options to purchase an aggregate of 8,612,580 shares of our Common Stock with exercise prices ranging from $0.4155 to $20.67 per share, (b) warrants to purchase an aggregate of 5,603,324 shares of our Common Stock with exercise prices ranging from $0.793 to $4.452 per share, and (c) 4,073,180 RSUs outstanding.

2025 Proxy Statement |  | 45 |  |

Under the terms of the Plans, the compensation committee will have discretion to determine the appropriate adjustment to the awards granted under our Plans in the event of a reverse stock split. Accordingly, if the reverse stock split is effected, the number of shares available for issuance under the Plans, as well as the number of shares subject to any outstanding award under the Plans, and the exercise price, grant price or purchase price relating to any such award under our Plans, will be proportionately adjusted by the compensation committee, as applicable, to reflect the reverse stock split. The compensation committee will also determine the treatment of fractional shares subject to outstanding awards under the Plans. Accordingly, pursuant to the authority as provided under each of the Plans, the compensation committee is expected to authorize the Company to effect any other changes necessary, desirable or appropriate to give effect to the reverse stock split, including any applicable technical, conforming changes to our Plans-based awards, which would also be proportionally adjusted by the ratio approved by the board of directors within the Split Ratio Range. Under the terms of the warrants, the number of warrant shares issuable upon exercise of the warrant shall be proportionally adjusted by the ratio approved by the board of directors within the Split Range Ratio, effective the date of the reverse stock split.

We have never declared or paid cash dividends on our Common Stock, nor do we have any plans to declare in the foreseeable future any distributions of cash or other property to holders of Common Stock, and we are not in arrears on any dividends. Therefore, we do not believe that the reverse stock split would have any effect with respect to future distributions, if any, to holders of our Common Stock.

Accounting Matters

The reverse stock split would not affect the par value of our Common Stock, which would remain unchanged at $0.001 per share. As a result, on the effective date, the present value of the stated capital on the Company’s balance sheet attributable to the Common Stock will be reduced based on the designated reverse stock split ratio, and the additional paid-in capital account will be increased with the amount by which the stated capital is reduced. The per share net loss and net book value of the Common Stock will be retroactively increased for each period because there will be fewer shares of Common Stock outstanding.

Beneficial Holders of Our Common Stock (Stockholders Who Hold in “Street Name”)

Upon the reverse stock split, we intend to treat shares held by stockholders in “street name,” through a broker, in the same manner as registered stockholders whose shares are registered in their names. Brokers would be instructed to effect the reverse stock split for their beneficial holders holding our Common Stock in “street name.” However, brokers may have different procedures than registered stockholders for processing the reverse stock split and making payment for fractional shares. Stockholders holding shares of our Common Stock with a broker and having any questions in this regard should contact their broker.

Effect on Registered “Book-Entry” Holders of Our Common Stock

If a stockholder holds registered shares in book-entry form with the transfer agent, no action needs to be taken to receive post- split shares or cash payment in lieu of any fractional share interest, if applicable. If such a stockholder is entitled to post- split shares, a transaction statement would automatically be sent to such stockholder’s address of record indicating the number of shares of our Common Stock held following the reverse stock split.

If such a stockholder is entitled to a payment in lieu of any fractional share interest, a check would be mailed to the stockholder’s registered address as soon as practicable after the effective time of the reverse stock split. By signing and cashing the check, stockholders would warrant that they owned the shares of our Common Stock for which they received a cash payment. The cash payment is subject to applicable federal and state income tax and state abandoned property laws. No stockholders would be entitled to receive interest for the period of time between the effective time of the reverse stock split and the date payment is received.

2025 Proxy Statement |  | 46 |  |

Effect on Registered Certificated Shares

Some stockholders hold their shares in certificated form or a combination of certificated and book-entry form. If any of a stockholder’s shares are held in certificated form, they will receive a letter of transmittal from Computershare as soon as practicable after the effective time of the reverse stock split. The letter of transmittal will be accompanied by instructions specifying how stockholders can exchange their certificate representing the pre-split shares for a statement of holding for their post-split shares. Please note, when sending Computershare their completed letter of transmittal, stockholders should ensure they enclose all of their original physical stock certificates with their letter of transmittal. It is recommended that stockholders send this presentation to Computershare by trackable mail, return receipt requested. After a stockholder submits their certificate representing the pre-split shares, together with a duly completed letter of transmittal, their post-split shares will be issued to them electronically in book-entry form. This means that, instead of receiving a new stock certificate, such stockholders will receive a statement of holding that indicates the number of post-split shares they own in book-entry form. We will no longer issue physical stock certificates unless a stockholder makes a specific request for a physical stock certificate representing the stockholder’s post-split shares.

Beginning on the effective date of the reverse stock split, each certificate representing pre-split shares will be deemed for all corporate purposes to evidence ownership of post-split shares. Stockholders will need to exchange their old certificates in order to effect transfers of shares on The Nasdaq Global Market. If a stockholder is entitled to a payment in lieu of any fractional shares, payment will be made as described above under “Principal Effects of the Reverse Stock Split on Our Common Stock; No Fractional Shares.”

STOCKHOLDERS SHOULD NOT DESTROY ANY SHARE CERTIFICATE(S) AND SHOULD NOT SUBMIT ANY CERTIFICATE(S) UNTIL REQUESTED TO DO SO.

As applicable, new share certificates evidencing post-split shares that are issued in exchange for pre-split shares representing restricted shares will contain the same restrictive legend as on the old certificates. For purposes of determining the term of the restrictive period applicable to the post-split shares, the time period during which a stockholder has held their existing pre-split shares will be included in the total holding period.

No Dissenters’ Rights

Under the Delaware General Corporation Law, stockholders are not entitled to dissenters’ rights with respect to the reverse stock split.

Material Federal Income Tax Consequences of the Reverse Stock Split

The following is a general summary of certain material U.S. federal income tax consequences of the reverse stock split to stockholders that hold their shares of Common Stock as capital assets for U.S. federal income tax purposes (generally, property held for investment). This summary is based upon the provisions of the U.S. Internal Revenue Code of 1986 (the “Code”) Treasury regulations promulgated thereunder, administrative rulings and judicial decisions, all as in effect as of the date hereof, and all of which are subject to change and differing interpretations, possibly with retroactive effect. Changes in these authorities or their interpretation may result in the U.S. federal income tax consequences of the Reverse Stock Split differing substantially from the consequences summarized below.

This summary is for general information purposes only and does not address all aspects of U.S. federal income taxation that may be relevant to stockholders in light of their particular circumstances, including the impact of the alternative minimum tax, the Medicare surtax on net investment income or the special tax accounting rules under Section 451(b) of the Code, or to stockholders that may be subject to special tax rules, including, without limitation: (i) banks, insurance companies, or other financial institutions; (ii) tax-exempt organizations; (iii) dealers in securities or commodities; (iv) regulated investment companies or real estate investment trusts; (v) partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes and their partners or members); (vi) traders in securities that elect to use the mark-to-market method of accounting; (vii) persons whose “functional currency” is not the U.S. dollar; (viii) persons holding our

2025 Proxy Statement |  | 47 |  |

Common Stock in a hedging transaction, “straddle,” “conversion transaction” or other risk reduction transaction; (ix) persons who acquired our Common Stock in connection with employment or the performance of services; (x) retirement plans; (xi) persons holding our Common Stock as “qualified small business stock” under Section 1202 of the Code; (xii) persons who are not U.S. Holders (as defined below); or (xiii) certain former citizens or long-term residents of the United States. In addition, this summary of certain material U.S. federal income tax consequences does not address the tax consequences arising under the laws of any foreign, state or local jurisdiction or any U.S. federal tax consequences other than U.S. federal income taxation (such as U.S. federal estate and gift tax consequences). If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds shares of our Common Stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner, the activities of the partnership, and certain determinations made at the partner level. Partnerships holding our Common Stock and the partners in such partnerships should consult their tax advisors regarding the tax consequences to them of the Reverse Stock Split.

We have not sought, and will not seek, an opinion of counsel or a ruling from the IRS regarding the U.S. federal income tax consequences of the Reverse Stock Split and there can be no assurance that the IRS will not challenge the statements and conclusions set forth below or that a court would not sustain any such challenge.

EACH STOCKHOLDER SHOULD CONSULT ITS TAX ADVISORS WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES OF THE REVERSE STOCK SPLIT TO SUCH STOCKHOLDER.

This summary addresses only stockholders that are U.S. Holders. For purposes of this discussion, a “U.S. Holder” is any beneficial owner of our Common Stock that, for U.S. federal income tax purposes, is or is treated as any of the following:

| • |  | an individual who is a citizen or resident of the United States;

| • |  | a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia;

| • |  | an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

| • |  | a trust that (i) is subject to the primary supervision of a U.S. court and all substantial decisions of which are subject to the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (ii) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

It is intended that the reverse stock split should constitute a “recapitalization” for U.S. federal income tax purposes. Assuming the reverse stock split qualifies as a “recapitalization” for U.S. federal income tax purposes, then, except as described below with respect to cash received in lieu of fractional shares, a stockholder should not recognize gain or loss as a result of the reverse stock split. A stockholder’s aggregate tax basis in the shares of the Common Stock received pursuant to the reverse stock split should equal the stockholder’s aggregate tax basis in the shares of the Common Stock surrendered (excluding any portion of such basis that is allocated to any fractional share of our Common Stock), and such stockholder’s holding period in the shares of the Common Stock received should include the holding period of the shares of the Common Stock surrendered. Treasury regulations promulgated under the Code provide detailed rules for allocating the tax basis and holding period of shares of Common Stock surrendered pursuant to the reverse stock split to shares of Common Stock received pursuant to the reverse stock split. Stockholders holding shares of Common Stock that were acquired on different dates and at different prices should consult their tax advisors regarding the allocation of the tax basis and holding period of such shares.

A stockholder who receives cash in lieu of a fractional share of Common Stock should be treated as first receiving such fractional share and then receiving cash in redemption of such fractional share. A stockholder who

2025 Proxy Statement |  | 48 |  |

receives cash in lieu of a fractional share in the reverse stock split should recognize capital gain or loss equal to the difference between the amount of the cash received in lieu of the fractional share and the portion of the stockholder’s adjusted tax basis allocable to the fractional share. Stockholders should consult their tax advisors regarding the tax effects to them of receiving cash in lieu of fractional shares based on their particular circumstances.

A stockholder may be subject to information reporting with respect to any cash received in exchange for a fractional share interest in a new share in the reverse stock split. Stockholders who are subject to information reporting and who do not provide a correct taxpayer identification number and other required information (such as by submitting a properly completed IRS Form W-9) may also be subject to backup withholding at the applicable rate. Any amount withheld under such rules is not an additional tax and may be refunded or credited against the stockholder’s U.S. federal income tax liability, provided that the required information is properly furnished in a timely manner to the IRS.

Vote Required: |  | Approval of an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the Company’s Common Stock at a ratio ranging from any whole number between 1-for-2 and 1-for-20, inclusive, as determined by our board of directors in its discretion, subject to our board of directors’ authority to abandon such amendments requires the affirmative vote of a majority of the shares present or represented by proxy and entitled to vote at the Annual Meeting. Abstentions have the same impact as votes “Against” the proposal. Brokers do not have discretion to vote on this proposal.

APPROVAL OF THE COMPANY’S AMENDED AND RESTATED EMPLOYEE STOCK PURCHASE PLAN

Proposal Four: Approval of the Company’s Amended and Restated ESPP to increase the available shares of the Company’s Common Stock under the plan by 1,451,500 and to increase the maximum number of shares of the Company’s Common Stock that may be provided as the result of the plan’s annual automatic increase to 3,000,000

General

Effective with our IPO in October 2020, the Company’s board of directors and its stockholders approved the Company’s Employee Stock Purchase Plan (the “ESPP”). The ESPP allows the Company’s employees to purchase shares of the Company’s Common Stock at a discount through payroll deductions. We are asking our shareholders to approve an amendment and restatement of the ESPP to increase the number of shares of Common Stock authorized for issuance under the ESPP by 1,451,500 and to provide that the maximum number of shares available under the ESPP automatically increases on the first trading day of each calendar year by an amount equal to the lesser of (i) 1% of the shares of Common Stock issued and outstanding on December 31st of the immediately preceding calendar year, (ii) (x) beginning with the fiscal year ending December 31, 2022, and continuing until (and including) the fiscal year ending December 31, 2025, 338,106 Shares and (y) beginning with the fiscal year ending December 31, 2026, and continuing until (and including) the fiscal year ending December 31, 2030, 3,000,000, and (iii) an amount determined by the board of directors.

We initially reserved 338,106 shares of Common Stock for issuance under the ESPP. In addition, pursuant to its terms, the number of shares of Common Stock available for issuance automatically increases on the first day of each fiscal year, beginning with the fiscal year ending December 31, 2022 and continuing until (and including) the fiscal year ending December 31, 2030, with the annual increase equal to the lesser of (i) 1% of the shares of Common Stock issued and outstanding on December 31st of the immediately preceding calendar year, (ii) 338,106, and (iii) an amount determined by the board of directors. As a result of the annual automatic increase, the number of shares of Common Stock available for issuance increased by 307,896 for the fiscal year ending December 31, 2022 and by 338,106 beginning with the fiscal year ending December 31, 2023 and continuing until (and including) the fiscal year ending December 31, 2025. As of March 1, 2025, 48,500 shares of Common Stock remained available for issuance under the ESPP. If this proposal is approved by our shareholders, the total shares available for issuance under the ESPP would increase by 1,451,500 and the maximum annual increase would increase from 338,106 to 3,000,000.

Reasons for Stockholder Approval.

The Company views the ESPP as an integral tool for attracting, retaining, and motivating employees. The ESPP promotes stock ownership by employees, thereby aligning their interests with those of the Company’s stockholders.

As of March 1, 2025, there were 48,500 shares of Common Stock available for issuance under the ESPP. Our board of directors believes the currently available shares are insufficient to meet the Company’s needs with respect to competing for qualified personnel in the competitive market in which it operates.

Accordingly, on or about April 15, 2025 our board of directors approved the Company’s Amended and Restated ESPP, which will increase the available shares under the ESPP by 1,451,500, subject to shareholder approval at the annual meeting, and change the automatic increase provisions under our ESPP to provide that the annual increase will be the lesser of (i) 1% of the shares of Common Stock issued and outstanding on December 31st of the immediately preceding calendar year, (ii) (x) beginning with the fiscal year ending December 31, 2022, and continuing until (and including) the fiscal year ending December 31, 2025, 338,106

2025 Proxy Statement |  | 50 |  |

Shares and (y) beginning with the fiscal year ending December 31, 2026, and continuing until (and including) the fiscal year ending December 31, 2030, 3,000,000, and (iii) an amount determined by the board of directors. Our board of directors believes that if this proposal is not approved, we may be at a disadvantage against our competitors when competing for qualified personnel, which could result in the need to increase cash compensation, thereby reducing resources available to meet our business needs.

We are asking our shareholders to approve the Company’s Amended and Restated ESPP, as required by the Internal Revenue Code.

Summary of the ESPP

The purpose of the ESPP is to assist eligible employees of the Company and its designated affiliates in acquiring stock ownership interest in the Company. The following is a summary of the material terms of the ESPP, which is qualified by reference to the complete text of the ESPP, as amended and restated, a copy of which is attached as Annex B to this Proxy Statement:

| • |  | All employees of the Company who meet certain service requirements are eligible to participate in the ESPP. However, employees who own 5% or more of the total combined voting power or value of the Company’s stock are not eligible to participate. As of April 16, 2025, approximately 285 employees are eligible to participate in the ESPP.

| • |  | The ESPP includes two components: (a) a component intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code of 1986, as amended (Code) (423 Component) and (b) a component that does not qualify as an “employee stock purchase plan” under Section 423 of the Code (Non-423 Component), under which options shall be granted in ways designed by the compensation committee to achieve desirable tax outcomes or other objectives for plan participants and the Company. Except as otherwise provided in the ESPP, both components will operate and be administered in the same manner.

| • |  | The ESPP operates with successive six-month offering periods. Unless otherwise specified by the compensation committee, these offering periods begin on September 1st and March 1st of each year (or if such dates are not trading days, then the first trading day immediately following such dates). During these offering periods, participants can elect to purchase shares of the Company’s Common Stock through payroll deductions.

| • |  | Participants may contribute up to 15% of their earnings towards the purchase of Common Stock. These contributions are made through payroll deductions, which accumulate during the offering period.

| • |  | The purchase price for shares under the ESPP is generally set at 85% of the fair market value of the Company’s Common Stock on either the first or last day of the offering period, whichever is lower. However, the compensation committee may, at is discretion, choose a higher per share purchase price, so long as that price is communicated to plan participants prior to the beginning of the offering period.

| • |  | As amended, an additional 1,451,000 shares of Common Stock will be reserved for issuance under the ESPP. The maximum number of shares available under the ESPP will automatically increase on the first trading day of each calendar year by an amount equal to the lesser of (i) 1% of the shares of Common Stock issued and outstanding on December 31st of the immediately preceding calendar year, (ii) 3,000,000, and (iii) an amount determined by the board of directors. As of April 16, 2025, the closing sales price per share of the Company’s Common Stock was $0.55.

| • |  | Rights granted under the ESPP are not transferable by the participant other than by will or the laws of descent and distribution. During the participant’s lifetime, the rights are exercisable only by the participant.

| • |  | The ESPP will be administered by the compensation committee or a designee of the compensation committee. The ESPP may be amended by the Company’s board of directors or compensation committee but may not be amended without prior stockholder approval to the extent required by Section 423 of the Code.

2025 Proxy Statement |  | 51 |  |

| • |  | The ESPP shall continue in effect until the earlier of (i) the termination of the ESPP by the Company’s board of directors or the compensation committee pursuant to the terms of the ESPP and (ii) the ten-year anniversary of the effective date of the amended and restated ESPP, with no new offering periods commencing on or after such ten-year anniversary.

U.S. Federal Income Tax Consequences

The following is a brief summary of certain United States federal income tax consequences generally arising with respect to the ESPP. This discussion does not address all aspects of the United States federal income tax consequences of participating in the ESPP that may be relevant to participants in light of their personal investment or tax circumstances and does not discuss any state, local or non-United States tax consequences of participating in the ESPP. Each participant is advised to consult his or her personal tax advisor concerning the application of the United States federal income tax laws to such participant’s particular situation, as well as the applicability and effect of any state, local or non-United States tax laws before taking any actions with respect to the ESPP.

423 Component Offerings

Under the 423 Component of the ESPP, no taxable income will be recognized by a participant, and no deductions will be allowable to the Company (or, if applicable, the affiliate employer), upon either the grant or the exercise of the purchase rights. Taxable income will not be recognized until there is a sale or other disposition of the shares acquired under the ESPP or in the event the participant should die while still owning the purchased shares.

If the participant sells or otherwise disposes of the purchased shares within two years after the start date of the option period in which the shares were acquired or within one year after the actual purchase date of those shares, whichever is later, then the participant will recognize ordinary income, in the year of sale or disposition, equal to the amount by which the fair market value of the shares on the purchase date exceeded the purchase price paid for those shares, and the Company (or, if appliable, the affiliate employer) will be entitled to an income tax deduction (subject to applicable limits under the Code, including, if applicable, those imposed by Section 162(m) of the Code), for the taxable year equal to the amount recognized as ordinary income by the participant. The amount of this ordinary income will be added to the participant’s basis in the shares and any resulting gain or loss recognized upon the sale or disposition will be a capital gain or loss. If the shares have been held for more than one year since the date of purchase, the gain or loss will be long-term.

If the participant sells or disposes of the purchased shares more than two years after the start date of the option period in which the shares were acquired and more than one year after the actual purchase date of those shares (a “qualifying disposition”), then the participant will recognize ordinary income in the year of sale or disposition equal to the lesser of (a) the amount by which the fair market value of the shares on the sale or disposition date exceeded the purchase price paid for those shares or (b) the applicable purchase price discount on the purchased shares, measured against the fair market value of the shares on the first day of that option period. Any additional gain upon the disposition will be taxed as a long-term capital gain. Alternatively, if the fair market value of the shares on the date of the sale or disposition is less than the purchase price, there will be no ordinary income and any loss recognized will be a long-term capital loss. The Company (or, if applicable, the affiliate employer) will not be entitled to an income tax deduction with respect to a qualifying disposition.

If the participant still owns the purchased shares at the time of death, the lesser of (i) the amount by which the fair market value of the shares on the date of death exceeds the purchase price or (ii) the applicable purchase price discount on the purchased shares, measured against the fair market value of the shares on the first day of the option period in which those shares were acquired will constitute ordinary income in the year of death. The Company (or, if applicable, the affiliate employer) will not be entitled to an income tax deduction with respect to a qualifying disposition.

Non-423 Component Offerings

If a purchase right is granted under the Non-423 Component of the ESPP, then to the extent a participant is subject to U.S. federal income tax, the participant will recognize ordinary income, in the year of purchase, in

2025 Proxy Statement |  | 52 |  |

an amount equal to the excess of the fair market value of the shares on the purchase date over the purchase price. The amount of such ordinary income will be added to the participant’s basis in the shares, and any additional gain or resulting loss recognized on the disposition of the shares, after such basis adjustment, will be a capital gain or loss. A capital gain or loss will be long-term if the participant holds the shares for more than one year after the purchase date. The Company (or, if applicable, the affiliate employer) may be entitled to a deduction in the year of purchase equal to the amount of ordinary income realized by the participant (subject to applicable limits under the Code, including, if applicable, those imposed by Section 162(m) of the Code).

The foregoing is only a summary of the U.S. federal income taxation of participants and the Company as to the participation in the ESPP. This discussion is not intended to be exhaustive and does not provide tax guidance to participants in the ESPP, as the consequences may vary. The summary does not address the effects of other federal taxes (including employment taxes or excise taxes, or taxability under Section 409A of the Code) or taxes imposed under state, local, or non-U.S. tax laws. The summary is not intended or written to be used, and cannot be used, for the purposes of avoiding tax penalties.

Registration with the SEC

If our stockholders approve this proposal, we will file with the SEC, as soon as reasonably practicable after such approval, a registration statement of Form S-8 relating to the additional shares available for issuance under the amended and restated ESPP.

Plan Benefits

It is not possible to determine how many eligible employees will participate in the ESPP in the future or their level of participation. Therefore, it is not possible to determine with certainty the dollar value or number of shares of Company Common Stock that will be distributed under the ESPP. Our non-employee directors do not participate in the ESPP. During 2024, Mr. Hutton, Ms. Harper Cowie and Mr. O’Kane purchased 16,139, 10,000 and 13,231 shares of Company Common Stock, respectively, under the ESPP. During 2024, our executive officers as a group purchased 39,370 shares of Company Common Stock under the ESPP, and our employees as a group (other than executive officers) purchased 432,473 shares of Company Common Stock under the ESPP.

Vote Required: |  | Approval of the amendment and restatement of the ESPP requires the affirmative vote of a majority of the shares present or represented by proxy and entitled to vote at the Annual Meeting. Abstentions have the same impact as votes “Against” the proposal. Brokers do not have discretion to vote on this proposal.
Board Recommendation: |  | OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE COMPANY’S AMENDED AND RESTATED ESPP TO INCREASE THE NUMBER OF SHARES RESERVED FOR ISSUANCE AND PROVIDED BY THE AUTOMATIC INCREASE THAT OCCURS ANNUALLY UNDER THE COMPANY’S ESPP. |  |

Annex A

CERTIFICATE OF AMENDMENT

OF THE

CERTIFICATE OF INCORPORATION

OF

BIODESIX, INC.

Biodesix, Inc., a corporation organized and existing under the laws of the State of Delaware (the “Corporation”), hereby certifies as follows:

FIRST: The name of the Corporation is Biodesix, Inc. The Corporation was originally incorporated under the name Elston Technologies, Inc. The Corporation’s original certificate of incorporation was filed with the office of the Secretary of State of the State of Delaware on December 23, 2005, and amended on October 30, 2020 (as amended, the Certificate of Incorporation”).

SECOND: This amendment to the Certificate of Incorporation has been duly authorized by the directors and the requisite stockholders of the Corporation in accordance with the provisions of Sections 228 and 242 of the Delaware General Corporation Law.

THIRD: The Certificate of Incorporation is hereby amended in the form set forth in the following resolution:

RESOLVED: The Certificate of Incorporation is hereby amended to include a new Section 4.5 in Article IV as follows:

4.5 Reverse Stock Split. Upon the filing and effectiveness of this Certificate of Amendment of the Certificate of Incorporation with the Secretary of State of the State of Delaware, each [ ]2 shares of Common Stock either issued and outstanding or held by the Corporation in treasury stock immediately prior to the Effective Time (as defined below) shall, automatically and without any action on the part of the respective holders thereof, be combined and converted into one (1) share of Common Stock without increasing or decreasing the par value of each share (the “Reverse Stock Split”).

No fractional interest in a share of Common Stock shall be deliverable upon the Reverse Stock Split. All shares of Common Stock (including fractions thereof) issuable upon the Reverse Stock Split held by a holder prior to the Reverse Stock Split shall be aggregated for purposes of determining whether the Reverse Stock Split would result in the issuance of any fractional share. Any fractional share resulting from such aggregation upon the Reverse Stock Split shall be rounded down to the nearest whole number. Each holder who would otherwise be entitled to a fraction of a share of Common Stock upon the Reverse Stock Split (after aggregating all fractions of a share to which such stockholder would otherwise be entitled) shall, in lieu thereof, be entitled to receive a cash payment (without interest) in an amount equal to the fraction to which the stockholder would otherwise be entitled multiplied by the closing price of the Corporation’s Common Stock as reported by The Nasdaq Stock Market LLC on the last trading day prior

2 | This amendment approves the combination of not less than 2 nor more than 20 shares of the Corporation’s Common Stock into one share of the Corporation’s Common Stock, with the specific ratio and the implementation and timing of such Reverse Stock Split to be determined in the discretion of the Corporation’s board of directors. If the Reverse Stock Split Proposal is approved by stockholders, the Certificate of Amendment filed with the Secretary of State of the State of Delaware will include only that reverse stock split ratio determined by the Corporation’s board of directors to be in the best interests of the Corporation and its stakeholders. The other amendments will be abandoned pursuant to Section 242(c) of the General Corporation Law of the State of Delaware. The Corporation’s board of directors may also elect not to effect any reverse stock split, in which case all proposed alternate amendments will be abandoned.

EMPLOYEE STOCK PURCHASE PLAN

(AMENDED AND RESTATED EFFECTIVE APRIL 15, 2025)

1. PURPOSE. The purpose of the Biodesix, Inc. Employee Share Purchase Plan (this “Plan”) is to provide eligible Employees of the Company and Participating Subsidiaries with a convenient means of acquiring an equity interest in the Company through payroll deductions or other contributions in order to enhance such employees’ sense of participation in the affairs of the Company.

This Plan includes two components: (a) a component intended to qualify as an “employee stock purchase plan” under Section 423 of the Code (the “423 Component”), the provisions of which shall be construed so as to extend and limit participation in a uniform and nondiscriminatory manner consistent with the requirements of Section 423 of the Code; and (b) a component that does not qualify as an “employee stock purchase plan” under Section 423 of the Code (the “Non-423 Component”), under which options shall be granted pursuant to rules, procedures or sub-plans adopted by the Committee designed to achieve tax, securities laws or other objectives for eligible Employees, the Company and its Participating Subsidiaries. Except as otherwise provided in this Plan, the Non-423 Component will operate and be administered in the same manner as the 423 Component.

3.   ELIGIBILITY.

(a)  Only Employees of the Company or a Participating Subsidiary shall be eligible to be granted Options under the Plan and, in no event may a Participant be granted an Option under the Plan following his or her Termination Date.

(b)  Any provisions of the Plan to the contrary notwithstanding, no Employee shall be granted an Option under the 423 Component of the Plan if (i) immediately after the grant, such Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company and/or hold outstanding Options or options to purchase stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of any of its Subsidiaries or (ii) such Option would permit his or her rights to purchase stock under all employee stock purchase plans (described in Section 423 of the Code) of the Company and its Subsidiaries to accrue at a rate that exceeds $25,000 of the Fair Market Value of such stock (determined at the time each such Option is granted) for each calendar year in which such Option is outstanding at any time. Except as otherwise determined by the Committee prior to the commencement of an Offering Period, no Participant may purchase more than 10,000 Shares during any Offering Period.

4. EXERCISE OF AN OPTION.

2025 Proxy Statement |  | B-3 |  |

(b)  An Employee who does not become a Participant on the first Enrollment Date on which he or she is eligible may thereafter become a Participant on any subsequent Enrollment Date by properly completing and submitting an election form by the deadline prescribed by the Company.

(c)  Payroll deductions for a Participant shall commence on the first payroll date following the Enrollment Date and shall end on the last payroll date in the Purchase Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 12 hereof.

6.   PAYROLL DEDUCTIONS.

(a)  A Participant shall elect to have payroll deductions made during a Purchase Period equal to no less than 1% of the Participant’s Compensation up to a maximum of 15% (or such greater amount as the Committee establishes from time to time). The amount of such payroll deductions shall be in whole percentages. All payroll deductions made by a Participant shall be credited to his or her Purchase Account. A Participant may not make any additional payments into his or her Purchase Account. Notwithstanding the foregoing or any provisions to the contrary in the Plan, the Committee may allow participants to make other contributions under the Plan via cash, check, or other means instead of payroll deductions if payroll deductions are not permitted under applicable local law, and for any Offering Period under the 423 Component, if the Committee determines that such other contributions are permissible under Section 423 of the Code.

(b)  Except as otherwise determined by the Committee prior to the commencement of an Offering Period, a Participant may not increase the rate of payroll deductions during an Offering Period. A Participant may decrease the rate of payroll deductions during an Offering Period by properly completing and submitting an election change form in accordance with the procedures prescribed by the Committee and/or any other forms required by the Committee and by following any other procedures as may be established by the Committee, in which case the new rate shall become effective as soon as administratively practicable after the Participant elects such change and shall continue for the remainder of the Offering Period unless changed as described below. Such change in the rate of payroll deductions may be made at any time during an Offering Period, but not more than one (1) change may be made effective during any Offering Period, except that a Participant may elect at any time during an Offering Period, regardless of whether the Participant previously decreased his or her contribution percentage, to reduce his or her contribution percentage to 0% and such change shall become effective as soon as administratively practicable after the Participant elects such change and shall continue for the remainder of the Offering Period unless changed as described below. A Participant may change his or her payroll deduction percentage under subsection (a) above for any subsequent Offering Period by properly completing and submitting an election change form in accordance with the procedures prescribed by the Committee. The change in amount shall be effective as of the first Enrollment Date following the date of filing of the election change form. Unless otherwise determined by the Committee prior to the commencement of an Offering Period, a payroll deduction election will automatically apply to the next Offering Period, unless otherwise cancelled or changed by the Participant prior to the commencement of such Offering Period.

(c)  Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a Participant’s payroll deductions may be decreased to 0% at any time during an Offering Period. Payroll deductions shall recommence at the rate provided in such Participant’s election form at the beginning of the first Offering Period which is scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 12 hereof.

7. GRANT OF OPTION. On the applicable Enrollment Date, each Participant in an Offering Period shall be granted an Option to purchase on the applicable Exercise Date a number of full Shares determined by dividing such Participant’s payroll deductions accumulated prior to such Exercise Date and retained in the Participant’s Purchase Account as of the applicable Exercise Date by the applicable Purchase Price.

8. EXERCISE OF OPTION. A Participant’s Option for the purchase of Shares shall be exercised automatically on the Exercise Date, and the maximum number of Shares subject to the Option shall be purchased for such

2025 Proxy Statement |  | B-4 |  |

Participant at the applicable Purchase Price with the accumulated payroll deductions in his or her Purchase Account. If the Fair Market Value of a Share on the first day of the current Offering Period in which a participant is enrolled is higher than the Fair Market Value of a Share on the first day of any subsequent Offering Period, the Company may establish procedures to automatically enroll such participant in the subsequent Offering Period and any funds accumulated in a participant’s account prior to the first day of such subsequent Offering Period will be applied to the purchase of shares on the Exercise Date immediately prior to the first day of such subsequent Offering Period. A participant does not need to file any forms with the Company to be automatically enrolled in the subsequent Offering Period.

No fractional Shares shall be purchased; any payroll deductions accumulated in a Participant’s Purchase Account which are not sufficient to purchase a full Share shall be retained in the Purchase Account for the next subsequent Purchase Period, subject to earlier withdrawal by the Participant as provided in Section 12 hereof. All other payroll deductions accumulated in a Participant’s Purchase Account and not used to purchase Shares on an Exercise Date shall be distributed to the Participant. During a Participant’s lifetime, a Participant’s Option is exercisable only by him or her. The Company shall satisfy the exercise of all Participants’ Options for the purchase of Shares through (a) the issuance of authorized but unissued Shares, (b) the transfer of treasury Shares, (c) the purchase of Shares on behalf of the applicable Participants on the open market through an independent broker and/or (d) a combination of the foregoing.

9. ISSUANCE OF STOCK. The Shares purchased by each Participant shall be issued in book entry form and shall be considered to be issued and outstanding to such Participant’s credit as of the end of the last day of each Purchase Period. The Committee may permit or require that shares be deposited directly in a Brokerage Account with one or more brokers designated by the Committee or to one or more designated agents of the Company, and the Committee may use electronic or automated methods of share transfer. The Committee may require that Shares be retained with such brokers or agents for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares, and may also impose a transaction fee with respect to a sale of Shares issued to a Participant’s credit and held by such a broker or agent. The Committee may permit Shares purchased under the Plan to participate in a dividend reinvestment plan or program maintained by the Company, and establish a default method for the payment of dividends.

10. APPROVAL BY STOCKHOLDERS. Notwithstanding the above, the Plan is expressly made subject to the approval of the stockholders of the Company within 12 months before or after the date the Plan is adopted by the Board. Such stockholder approval shall be obtained in the manner and to the degree required under applicable federal and state law. If the Plan is not so approved by the stockholders within 12 months before or after the date the Plan is adopted by the Board, this Plan shall not come into effect.

11.   ADMINISTRATION.

(a)Powers and Duties of the Committee. The Plan shall be administered by the Committee. Subject to the provisions of the Plan, Section 423 of the Code and the regulations thereunder with respect to the 423 Component, the Committee shall have the discretionary authority to determine the time and frequency of granting Options, the duration of Offering Periods and Purchase Periods, the terms and conditions of the Options and the number of Shares subject to each Option. The Committee shall also have the discretionary authority to do everything necessary and appropriate to administer the Plan, including, without limitation, interpreting the provisions of the Plan (but any such interpretation shall not be inconsistent with the provisions of Section 423 of the Code with respect to the 423 Component). All actions, decisions and determinations of, and interpretations by the Committee with respect to the Plan shall be final and binding upon all Participants and upon their executors, administrators, personal representatives, heirs and legatees. No member of the Board or the Committee shall be liable for any action, decision, determination or interpretation made in good faith with respect to the Plan or any Option granted hereunder. With respect to the 423 Component, an Offering Period shall be administered so as to ensure that all Participants have the same rights and privileges as provided by Section 423(b)(5) of the Code.

2025 Proxy Statement |  | B-5 |  |

(b)Administrator. The Company, Board or the Committee may engage the services of a brokerage firm or financial institution to perform certain ministerial and procedural duties under the Plan including, but not limited to, mailing and receiving notices contemplated under the Plan, determining the number of Purchased Shares for each Participant, maintaining or causing to be maintained the Purchase Account and the Brokerage Account, disbursing funds maintained in the Purchase Account or proceeds from the sale of Shares through the Brokerage Account, and filing with the appropriate tax authorities proper tax returns and forms (including information returns) and providing to each Participant statements as required by law or regulation.

(c)Indemnification. Each person who is or shall have been (i) a member of the Board, (ii) a member of the Committee, or (iii) an officer or employee of the Company to whom authority was delegated in relation to this Plan, shall be indemnified and held harmless by the Company against and from any loss, cost, liability or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit or proceeding against him or her; provided, however, that he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf, unless such loss, cost, liability or expense is a result of his or her own willful misconduct or except as expressly provided by statute.

The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s certificate of incorporation or bylaws, any contract with the Company, as a matter of law, or otherwise, or of any power that the Company may have to indemnify them or hold them harmless.

12. WITHDRAWAL. A Participant may withdraw from the Plan by properly completing and submitting to the Company a withdrawal form in accordance with the procedures prescribed by the Committee, which must be submitted prior to the date specified by the Committee before the last day of the applicable Offering Period. Upon withdrawal, any payroll deductions credited to the Participant’s Purchase Account prior to the effective date of the Participant’s withdrawal from the Plan will be returned to the Participant. No further payroll deductions for the purchase of Shares will be made during subsequent Offering Periods, unless the Participant properly completes and submits an election form, by the deadline prescribed by the Company in respect of such Offering Period. A Participant’s withdrawal from an offering will not have any effect upon his or her eligibility to participate in the Plan or in any similar plan that may hereafter be adopted by the Company.

13. TERMINATION OF EMPLOYMENT. On the Termination Date of a Participant for any reason prior to the applicable Exercise Date, whether voluntary or involuntary, and including termination of employment due to retirement, death or as a result of liquidation, dissolution, sale, merger or a similar event affecting the Company or a Participating Subsidiary, the corresponding payroll deductions credited to his or her Purchase Account will be returned to him or her or, in the case of the Participant’s death, to the person or persons entitled thereto under Section 16, and his or her Option will be automatically terminated.

14. INTEREST. No interest shall accrue on the payroll deductions of a Participant in the Plan.

15.   STOCK.

(a)  The stock subject to Options shall be common stock of the Company as traded on NASDAQ or on such other exchange as the Shares may be listed.

(b)  Subject to adjustment upon changes in capitalization of the Company as provided in Section 18 hereof, the maximum number of Shares which shall be initially made available for sale under the Plan shall be 1,789,606 Shares. In addition, subject to adjustments upon changes in capitalization of the Company as provided

2025 Proxy Statement |  | B-6 |  |

in Section 18 hereof, the maximum number of Shares which shall be made available for sale under the Plan shall automatically increase on the first day of each fiscal year, beginning with the fiscal year ending December 31, 2022, and continuing until (and including) the fiscal year ending December 31, 2030, with such annual increase equal to the lesser of (i) (x) beginning with the fiscal year ending December 31, 2022, and continuing until (and including) the fiscal year ending December 31, 2025, 338,106 Shares and (y) beginning with the fiscal year ending December 31, 2026, and continuing until (and including) the fiscal year ending December 31, 2030, 3,000,000, (ii) 1% of the number of Shares issued and outstanding on December 31 of the immediately preceding fiscal year, and (iii) an amount determined by the Board. If, on a given Exercise Date, the number of Shares with respect to which Options are to be exercised exceeds the number of Shares then available under the Plan, the Committee shall make a pro rata allocation of the Shares remaining available for purchase in as uniform a manner as shall be practicable and as it shall determine to be equitable.

(c)  A Participant shall have no interest or voting right in Shares covered by his or her Option until such Option has been exercised and the Participant has become a holder of record of Shares acquired pursuant to such exercise.

16. DESIGNATION OF BENEFICIARY. The Committee may permit Participants to designate beneficiaries to receive any Purchased Shares or payroll deductions, if any, in the Participant’s accounts under the Plan in the event of such Participant’s death. Beneficiary designations shall be made in accordance with procedures prescribed by the Committee. If no properly designated beneficiary survives the Participant, the Purchased Shares and payroll deductions, if any, will be distributed to the Participant’s estate.

17. ASSIGNABILITY OF OPTIONS. Neither payroll deductions credited to a Participant’s Purchase Account nor any rights with regard to the exercise of an Option or to receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 16 hereof) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw from an Offering Period in accordance with Section 12 hereof.

18.   ADJUSTMENT OF NUMBER OF SHARES SUBJECT TO OPTIONS.

(a)Adjustment. Subject to any required action by the stockholders of the Company, the maximum number of securities available for purchase under the Plan, as well as the price per security and the number of securities covered by each Option under the Plan which has not yet been exercised shall be appropriately adjusted in the event of any a stock split, reverse stock split, stock dividend, combination or reclassification of the common stock of the Company, or any other increase or decrease in the number of Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Board or the Committee, whose determination in that respect shall be final, binding and conclusive. If any such adjustment would result in a fractional security being available under the Plan, such fractional security shall be disregarded. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Option. With respect to the 423 Component, the Options granted pursuant to the Plan shall not be adjusted in a manner that causes the Options to fail to qualify as options issued pursuant to an “employee stock purchase plan” within the meaning of Section 423 of the Code.

(b)Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Board, and the Board may either provide for the purchase of Shares as of the date on which such Offering Period terminates or return to each Participant the payroll deductions credited to such Participant’s Purchase Account.

2025 Proxy Statement |  | B-7 |  |

(c)Merger or Asset Sale. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding Option shall be assumed or an equivalent option substituted by the successor corporation or a parent or subsidiary of the successor corporation, unless the Board determines, in the exercise of its sole discretion, that in lieu of such assumption or substitution to either terminate all outstanding Options and return to each Participant the payroll deductions credited to such Participant’s Purchase Account or to provide for the Offering Period in progress to end on a date prior to the consummation of such sale or merger.

19.   AMENDMENTS OR TERMINATION OF THE PLAN.

(a)  The Board or the Committee may at any time and for any reason amend, modify, suspend, discontinue or terminate the Plan without notice; provided that no Participant’s existing rights in respect of existing Options are adversely affected thereby. To the extent necessary to comply with Section 423 of the Code (or any other applicable law, regulation or stock exchange rule), the Company shall obtain stockholder approval in such a manner and to such a degree as required.

(b)  Without stockholder consent and without regard to whether any Participant rights may be considered to have been “adversely affected,” the Board or the Committee shall be entitled to change the Purchase Price, Offering Periods, Purchase Periods, eligibility requirements, limit or increase the frequency and/or number of changes in the amount withheld during a Purchase Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in an amount less than or greater than the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Shares for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Board or the Committee determines in its sole discretion advisable which are consistent with the Plan; provided, however, that changes to (i) the Purchase Price, (ii) the Offering Period, (iii) the Purchase Period, (iv) the maximum percentage of Compensation that may be deducted pursuant to Section 6(a) or (v) the maximum number of Shares that may be purchased in a Purchase Period, shall not be effective until communicated to Participants in a reasonable manner, with the determination of such reasonable manner in the sole discretion of the Board or the Committee.

20. NO OTHER OBLIGATIONS. The receipt of an Option pursuant to the Plan shall impose no obligation upon the Participant to purchase any Shares covered by such Option. Nor shall the granting of an Option pursuant to the Plan constitute an agreement or an understanding, express or implied, on the part of the Company to employ the Participant for any specified period.

21. NOTICES AND COMMUNICATION. Any notice or other form of communication which the Company or a Participant may be required or permitted to give to the other shall be provided through such means as designated by the Committee, including but not limited to any paper or electronic method.

22.   CONDITION UPON ISSUANCE OF SHARES.

(a)  Shares shall not be issued with respect to an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the 1933 Act and the 1934 Act and the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b)  As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.

2025 Proxy Statement |  | B-8 |  |

23. GENERAL COMPLIANCE. The Plan will be administered and Options will be exercised in compliance with the 1933 Act, the 1934 Act and all other applicable securities laws and Company policies, including without limitation, any insider trading policy of the Company.

24. TERM OF THE PLAN. The Plan shall become effective upon the earlier to occur of (i) its adoption by the Board and (ii) its approval by the stockholders of the Company (the earlier of such events, the “Effective Date”), and shall continue in effect until the earlier of (A) the termination of the Plan pursuant to Section 19 hereof and (B) the ten-year anniversary of the Effective Date, with no new Offering Periods commencing on or after such ten-year anniversary.

25. GOVERNING LAW. The Plan and all Options granted hereunder shall be construed in accordance with and governed by the laws of the State of Delaware without reference to choice of law principles and subject in all cases to the Code and the regulations thereunder.

26. NON-U.S. PARTICIPANTS. To the extent permitted under Section 423 of the Code, without the amendment of the Plan, the Company may provide for the participation in the Plan by Employees who are subject to the laws of foreign countries or jurisdictions on such terms and conditions different from those specified in the Plan as may in the judgment of the Company be necessary or desirable to foster and promote achievement of the purposes of the Plan and, in furtherance of such purposes the Company may make such modifications, amendments, procedures, subplans and the like as may be necessary or advisable to comply with provisions of laws of other countries or jurisdictions in which the Company or the Participating Subsidiaries operate or have employees. Each subplan shall constitute a separate “offering” under this Plan in accordance with Treas. Reg. §1.423-2(a) and, to the extent inconsistent with the requirements of Section 423, any such subplan shall be considered part of the Non-423 Component, and rights granted thereunder shall not be required by the terms of the Plan to comply with Section 423 of the Code.

27. SECTION 409A. The 423 Component is exempt from the application of Section 409A of the Code, and any ambiguities herein shall be interpreted to so be exempt from Section 409A of the Code. The Non-423 Component is intended to be exempt from the application of Section 409A of the Code under the short-term deferral exception and any ambiguities shall be construed and interpreted in accordance with such intent. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Committee determines that an option granted under the Plan may be subject to Section 409A of the Code or that any provision in the Plan would cause an option under the Plan to be subject to Section 409A, the Committee may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the Committee determines is necessary or appropriate, in each case, without the participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Section 409A of the Code, but only to the extent any such amendments or action by the Committee would not violate Section 409A of the Code. Notwithstanding the foregoing, the Company shall have no liability to a participant or any other party if the option under the Plan that is intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any action taken by the Committee with respect thereto.
