#### PROXY STATEMENT

#### FOR THE 2026 ANNUAL MEETING OF STOCKHOLDERS

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

#### June 4, 2026

#### QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

#### Why did I receive a notice regarding the availability of proxy materials on the internet?
Pursuant to rules adopted by the Securities and Exchange Commission (the "SEC"), we have elected to provide access to our proxy materials over the Internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the "Notice") because the Board of Directors (sometimes referred to as the "Board") of Pulmonx Corporation (referred to herein as "Pulmonx," the "Company," "we," "our" or "us") is soliciting your proxy to vote at the 2026 Annual Meeting of Stockholders (the "Annual Meeting"), including at any adjournments or postponements of the Annual Meeting. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice.

On or about April 22, 2026, we expect to mail to our stockholders the Notice containing instructions on how to access this proxy statement for the Annual Meeting (the "Proxy Statement") and our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "Annual Report on Form 10-K"). The Proxy Statement and the Annual Report on Form 10-K can be accessed directly at https://investors.pulmonx.com.

#### Will I receive any other proxy materials by mail?
No, you will not receive any other proxy materials by mail unless you request a paper copy of the proxy materials. To request that a full set of the proxy materials be sent to your specified postal address, please visit www.proxyvote.com, call 1-800-579-1639 or send an email to sendmaterial@proxyvote.com.

#### When and where is the Annual Meeting?
The Annual Meeting will be held virtually through a live webcast at http://www.virtualshareholdermeeting.com/LUNG2026. Whether or not you expect to attend the Annual Meeting, please vote as soon as possible by one of the methods described in the proxy materials for the Annual Meeting so that your shares will be represented and voted at the Annual Meeting.

We believe that holding the Annual Meeting in a virtual format invites stockholder participation, while reducing the costs to stockholders and the Company associated with an in-person meeting. This balance allows the Annual Meeting to remain focused on matters directly relevant to the interests of stockholders in an efficient way.

#### How do I attend the Annual Meeting?
You are entitled to attend the Annual Meeting if you were a stockholder as of the close of business on the record date, April 7, 2026 (the "Record Date"), or you hold a valid proxy to vote at the Annual Meeting.

If, on the Record Date, your shares were registered directly in your name with the Company's transfer agent, Equiniti Trust Company, LLC then you are a stockholder of record. To attend the Annual Meeting, you will need to visit http://www.virtualshareholdermeeting.com/LUNG2026 and enter the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials.

If, on the Record Date, your shares were held, not in your name, but rather in an account through an intermediary, such as a broker, bank or other nominee, then you are the beneficial owner of shares held in "street name," and this Proxy Statement and the accompanying proxy materials are being forwarded to you by your broker, bank or other nominee,

------

#### **TABLE OF CONTENTS**
which is considered to be the stockholder of record with respect to those shares. As a stockholder holding shares in street name, you must register in advance to attend, and to vote during, the Annual Meeting. To register, follow the instructions from your broker, bank, or other nominee included with these proxy materials to obtain a legal proxy or contact your nominee to request a proxy form.

Questions may be submitted during the Annual Meeting by accessing the virtual meeting platform at http://www.virtualshareholdermeeting.com/LUNG2026 with your 16-digit control number and following the instructions to submit a question. During the question and answer session of the Annual Meeting, we will address questions pertinent to meeting matters, subject to time constraints. Questions that are substantially similar may be grouped and answered once to avoid repetition. To allow us to respond to questions in the allotted time, we may limit each stockholder to one question.

We encourage you to access the Annual Meeting before it begins. The Annual Meeting will begin promptly at 8:00 a.m. Pacific Daylight Time, with log-in beginning at 7:45 a.m., on June 4, 2026.

If you have difficulty accessing the Annual Meeting, please contact the support numbers available at http://www.virtualshareholdermeeting.com/LUNG2026 on the day of the Annual Meeting. Technicians will be available to assist you.

#### Will a list of stockholders as of the Record Date be available?
A list of our stockholders as of April 7, 2026 will be available at our headquarters located at 700 Chesapeake Drive, Redwood City, California 94063 for inspection by stockholders of record for the ten days prior to the Annual Meeting. If you want to inspect the stockholder list, please contact our Secretary at investors@pulmonx.com to schedule an appointment.

#### Who is entitled to vote at the Annual Meeting?
You are entitled to participate in and vote at the Annual Meeting if you were a stockholder of record as of the close of business on the Record Date, April 7, 2026, or hold a legal proxy provided by your bank, broker or nominee for the Annual Meeting.

As of the Record Date, 42,237,203 shares of Pulmonx common stock were outstanding. Holders are entitled to one vote per share.

#### How can I vote at the Annual Meeting?
If you were a stockholder of record as of the Record Date, or you hold a legal proxy provided by your bank, broker or nominee for the Annual Meeting, you may vote during the Annual Meeting by following the instructions available on the meeting website at http://www.virtualshareholdermeeting.com/LUNG2026.

If you are a stockholder of record, you will need to enter the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials. If you are a beneficial owner of shares registered in the name of your broker, bank or other nominee, you must obtain a valid proxy from your broker, bank or other nominee in order to vote at the Annual Meeting. Follow the instructions from your broker, bank, or other nominee included with these proxy materials or contact your nominee to request a proxy form.

Whether or not you plan to attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the Annual Meeting. For information on how to vote prior to the Annual Meeting, see "How can I vote my shares without attending the Annual Meeting?"

#### How can I vote my shares without attending the Annual Meeting?
You may submit a proxy by telephone, via the Internet or by mail.

&nbsp;&nbsp;&nbsp;&nbsp;• *Submitting a Proxy by Telephone*: If you are a stockholder of record, you can submit your proxy by calling the telephone number specified on the proxy card that you received with the proxy materials. You must have the 16-digit control number that appears on your proxy card available when submitting your proxy over the telephone. If your shares are held in the name of a broker, bank or other nominee, follow the telephone voting instructions, if any, provided on your voting instruction card.

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• *Submitting a Proxy via the Internet*: You may submit your proxy or voting instructions over the Internet by following the instructions on the proxy card or voting instruction form.

&nbsp;&nbsp;&nbsp;&nbsp;• *Submitting a Proxy by Mail*: You can submit your proxy or voting instructions by completing and signing the separate proxy card or voting instruction form you received and mailing it in the accompanying prepaid and addressed envelope.

By casting your vote in any of the three ways listed above, you are authorizing the persons named in the accompanying proxy card as "proxies" to vote your shares in accordance with your instructions. All shares that have been properly voted, and not revoked, will be voted at the Annual Meeting.

Internet proxy voting is provided to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies.

If you attend the Annual Meeting, you may withdraw a prior proxy and vote online during the Annual Meeting if you so choose. For more information on how to revoke a proxy, see "Can I change my vote after submitting my proxy?"

#### What am I voting on?
There are three matters scheduled for a vote at the Annual Meeting:

&nbsp;&nbsp;&nbsp;&nbsp;• *Proposal No. 1* —To elect each of our Board's three nominees, Thomas W. Burns, Georgia Garinois-Melenikiotou, and Dana G. Mead, Jr., as a Class III director, to hold office until the 2029 Annual Meeting of Stockholders and until their successors are elected and qualified or until their earlier death, resignation or removal;

&nbsp;&nbsp;&nbsp;&nbsp;• *Proposal No. 2* —To ratify the selection by the Audit Committee of our Board of BDO USA, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026; and

&nbsp;&nbsp;&nbsp;&nbsp;• *Proposal No. 3* —To conduct a non-binding advisory vote to approve our executive compensation.

#### What if another matter is properly brought before the Annual Meeting?
As of the date of this Proxy Statement, the Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. However, if any other matter is properly brought before the Annual Meeting, it is the intention of the proxies to vote on such matter in accordance with their best judgment and in their discretion.

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

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, via the Internet, by mail or online at the Annual Meeting, your shares will not be voted. If you return your signed and dated proxy card to us before the Annual Meeting without marking your voting selections, proxies named in the proxy card will vote your shares in accordance with our Board's recommendations.

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

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other nominee how to vote your shares, your broker, bank or other nominee may still be able to vote your shares in its discretion. In this regard, under the rules of the New York Stock Exchange ("NYSE"), brokers, banks and other securities intermediaries that are subject to NYSE rules may use their discretion to vote your "uninstructed" shares with respect to matters considered to be "routine" under NYSE rules, but not with respect to "non-routine" matters. In this regard, Proposal No. 1, the election of directors, and Proposal No. 3, the approval, on a non-binding advisory basis, of our executive compensation, are considered to be "non-routine" under NYSE rules, meaning that your broker may not vote your shares on those proposals in the absence of your voting instructions. However, Proposal No. 2, the ratification of an independent registered accounting firm, is considered to be a "routine" matter under NYSE rules, meaning that if you do not return voting instructions to your broker, bank or other nominee by its deadline, your shares may be voted by your broker, bank or other nominee in its discretion.

------

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

#### How are votes counted?
Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count, (i) for Proposal No. 1 to elect directors, votes "For," votes "Withhold" and broker non-votes; and (ii) with respect to Proposal No. 2, the ratification of an independent registered accounting firm, and Proposal No. 3, approval, on a non-binding advisory basis, of our executive compensation, votes "For" and "Against," abstentions and, if applicable, broker non-votes.

#### What are "broker non-votes"?
As discussed above, when a beneficial owner of shares held in street name does not give voting instructions to his or her bank, broker or other nominee holding his or her shares as to how to vote on matters deemed to be "non-routine" under applicable rules, such broker, bank or other nominee cannot vote the shares. These un-voted shares are counted as "broker non-votes." Proposal Nos. 1 and 3 are considered to be "non-routine" under applicable rules and we therefore expect broker non-votes to exist in connection with these proposals.

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

#### What are the voting requirements to elect directors and approve the other proposals described in the Proxy Statement?
The following table summarizes the minimum vote needed to elect directors and approve each of the matters scheduled for vote at the Annual Meeting and the effect of abstentions and broker non-votes.

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Proposal** <br>**No** | **Proposal Description** | **Vote Required for Approval** | **Effect of Abstentions** | **Effect of** <br>**Broker Non-**<br>**Votes**  |
| 1 | Election of Directors. | Nominees receiving the most "For" votes from the holders of shares present or represented by proxy and entitled to vote on the matter; withheld votes will have no effect. | Not applicable. | No effect; <br>no broker discretion to vote.  |
| 2 | Ratification of the selection of BDO USA, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. | "For" votes from the holders of a majority of shares present or represented by proxy and entitled to vote on the matter. | Against. | Not applicable.<sup>(1)</sup>  |
| 3 | Non-binding advisory approval of our executive compensation. | "For" votes from the holders of a majority of shares present or represented by proxy and entitled to vote on the matter. | Against. | No effect; <br>no broker discretion to vote. |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) This proposal is considered to be a "routine" matter under applicable rules. Accordingly, if you hold your shares in street name and do not provide voting instructions to your broker, bank or other nominee that holds your shares, your broker, bank or other nominee has discretionary authority under applicable rules to vote your shares.

#### Who is paying for this proxy solicitation?
We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies online, by telephone, or by other means of communication. Directors and

------

#### **TABLE OF CONTENTS**
employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokers, banks and other nominees for the cost of forwarding proxy materials to beneficial owners.

#### What does it mean if I receive more than one Notice?
If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notices to ensure that all your shares are voted.

#### Can I change my vote after submitting my proxy?
*Stockholders of Record: Shares Registered in Your Name* 

Yes. Proxies may be revoked at any time before they are exercised at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

&nbsp;&nbsp;&nbsp;&nbsp;• you may send written notice that you are revoking your proxy to Pulmonx, Attn: Secretary, 700 Chesapeake Drive, Redwood City, California 94063;

&nbsp;&nbsp;&nbsp;&nbsp;• you may submit a proxy on a later date by telephone or Internet before 11:59 p.m. Eastern Daylight Time on June 3, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;• you may submit another properly completed proxy with a later date; or

&nbsp;&nbsp;&nbsp;&nbsp;• you may attend the Annual Meeting and vote electronically during the Annual Meeting. However, simply attending the Annual Meeting will not, by itself, revoke or change your previously granted proxy.

Your most current proxy is the one that is counted.

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

For shares held beneficially in street name, you may change your vote by submitting new voting instructions to your bank, broker or other nominee following the instructions it has provided, or, if you have obtained a legal proxy from your bank, broker or nominee giving you the right to vote your shares, by attending the Annual Meeting and voting electronically.

#### What is the quorum requirement?
A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the voting power of the outstanding shares entitled to vote are present at the meeting or represented by proxy. On the Record Date, there were 42,237,203 shares outstanding and entitled to vote.

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

#### How can I find out the results of the voting at the Annual Meeting?
Preliminary voting results will be announced at the Annual Meeting. Final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a current report on Form 8-K within four business days after the Annual Meeting, we intend to file a current report on Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an amended report on Form 8-K to disclose the final results.

#### **TABLE OF CONTENTS**

#### PROPOSAL NO. 1

#### ELECTION OF DIRECTORS

The Board of Directors presently has seven members. Currently, we have two directors in Class I, two directors in Class II and three directors in Class III, each serving a staggered three-year term. There are three directors in Class III whose term of office expires in 2026, all of whom are standing for election at the Annual Meeting: Thomas W. Burns, Georgia Garinois-Melenikiotou, and Dana G. Mead, Jr. Each director nominee is currently a director of the Company and was previously elected by the stockholders. If elected at the Annual Meeting, Ms. Garinois-Melenikiotou and Messrs. Burns and Mead would serve until the 2029 Annual Meeting of Stockholders and until their successors have been duly elected and qualified, or, if sooner, until the director's death, resignation or removal.

If any of the nominees become unavailable for election as a result of an unexpected occurrence, the Board of Directors may designate a substitute nominee, in which event the persons named in the enclosed proxy will vote for the election of such substitute nominee, unless the Board of Directors chooses to reduce the number of directors serving on the Board of Directors. Ms. Garinois-Melenikiotou and Messrs. Burns and Mead have each consented to being named as nominees in this Proxy Statement and have agreed to serve if elected. We have no reason to believe that Ms. Garinois-Melenikiotou and Messrs. Burns and Mead will be unable to serve if elected.

The following is a brief biography of the Class III director nominees standing for election at the Annual Meeting and each of our Class I and Class II directors continuing to serve on the Board of Directors, including their respective ages, as of March 31, 2026. Each biography includes information regarding the specific experience, qualifications, attributes or skills that led the Nominating and Corporate Governance Committee and the Board of Directors to determine that the applicable nominee, and each current director, should serve as a member of the Board of Directors.

#### Class III Director Nominees for Election for a Three-year Term Expiring at the 2029 Annual Meeting of Stockholders
*Thomas W. Burns, age 65, has served as a member of our Board since September 2020. Since December 2021, Mr. Burns has served as Chairman of the Board and Chief Executive Officer of Glaukos Corporation, a medical technology and pharmaceutical company ("Glaukos"). Mr. Burns has served as Chief Executive Officer and a member of the board of directors of Glaukos since March 2002, and additionally served as President from March 2002 to March 2022. From October 2009 until June 2015, Mr. Burns served as a member and the Chairman of the board of directors of DOSE Medical Corporation, a medical technology company. From March 2010 until June 2015, Mr. Burns served as DOSE Medical Corporation's Chief Executive Officer and President. From July 2018 until August 2019, Mr. Burns served on the board of directors of Avedro, Inc., prior to its acquisition by Glaukos. Mr. Burns holds a B.A. from Yale University.* 

We believe that Mr. Burns is qualified to serve as a member of our Board because of his extensive leadership and management experience in the medical technology industry and his experience on private and public company boards.

*Georgia Garinois-Melenikiotou, age 66, has served as a member of our Board of Directors since September 2020. Ms. Garinois-Melenikiotou served as Executive Vice President, Corporate Marketing at The Estée Lauder Companies, a global beauty products company, from January 2015 to July 2020, and as Senior Vice President, Corporate Marketing from April 2010 through December 2014. Prior to The Estée Lauder Companies, Ms. Garinois-Melenikiotou spent 27-years at Johnson & Johnson, a global manufacturer of medical devices, pharmaceutical products and consumer packaged goods, including in several senior leadership positions, most recently as President, Beauty Global Business Unit Strategy and New Growth from 2007 to 2010 and, from 2006 to 2007, as President, Beauty Care, EAME.

#### INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

#### Overview
We are committed to exercising good corporate governance practices. In furtherance of this commitment, we regularly monitor developments in the area of corporate governance and review our processes, policies and procedures in light of such developments. Key information regarding our corporate governance initiatives can be found on the Investor Relations section of our website, investors.pulmonx.com, including our Corporate Governance Guidelines, Code of Business Conduct and Ethics, Anti-Corruption Policy, Insider Trading Policy, Stock Ownership Policy, and Whistleblower Policy, as well as the charters for our Audit, Compensation and Nominating and Corporate Governance Committees. Information contained on our website is not incorporated by reference in, or considered to be a part of, this Proxy Statement. We believe that our corporate governance policies and practices, including the substantial percentage of independent directors on our Board and the appointment of an independent Board chair, empower our independent directors to effectively oversee our management—including the performance of our Chief Executive Officer—and provide an effective and appropriately balanced board governance structure.

#### Independence of The Board of Directors
As required under the listing standards of The Nasdaq Stock Market LLC (the "Nasdaq Listing Standards"), a majority of the members of a listed company's board of directors must qualify as "independent," as affirmatively determined by the board of directors. Our Board consults with our counsel to ensure that its determinations are consistent with relevant securities and other laws and regulations regarding the definition of "independent," including those set forth in pertinent Nasdaq Listing Standards, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, our Board has affirmatively determined that the following six directors are independent directors within the meaning of the applicable Nasdaq Listing Standards: Messrs. Burns, Ferrari, Florin, and Mead and Mses. Garinois-Melenikiotou and Sullivan. In making this determination, the Board of Directors found that none of these directors, or nominees for director, had a material or other disqualifying relationship with the Company. Our Board determined that Mr. French is not considered independent given his position as our Chief Executive Officer.

#### Board Leadership Structure
Our Board of Directors has an independent chair, Mr. Mead (the "Board Chair"), who has authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Board Chair has substantial ability to shape the work of the Board. The Company believes that separation of the positions of Board Chair and Chief Executive Officer reinforces the independence of the Board in its oversight of the business and affairs of the Company. In addition, the Company believes that having an independent Board Chair creates an environment that is more conducive to objective evaluation and oversight of management's performance, increasing management accountability and improving the ability of the Board to monitor whether management's actions are in the best interests of the Company and its stockholders. As a result, the Company believes that having an independent Board Chair can enhance the effectiveness of the Board as a whole.

#### Role of the Board in Risk Oversight
Our Board of Directors believes that risk management is an important part of establishing, updating and executing on our business strategy. Our Board of Directors, as a whole and at the committee level, has oversight responsibility relating to risks that could affect the corporate strategy, business objectives, compliance, operations and the financial condition and performance of the Company. Our Board of Directors focuses its oversight on the most significant risks facing the Company and, on its processes, to identify, prioritize, assess, manage and mitigate those risks. Our Board of Directors and its committees receive regular reports from members of the Company's senior management on areas of material risk to the Company, including strategic, operational, financial, cybersecurity, legal and regulatory. Our Board of Directors considers this information and provides feedback, makes recommendations, and, as appropriate, authorizes or directs management to address particular exposures to risk. While our Board of Directors has an oversight role, management is principally tasked with direct responsibility for management and assessment of risks and the implementation of processes and controls to mitigate their effects on the Company.

------

#### **TABLE OF CONTENTS**
The Audit Committee is responsible for overseeing our financial reporting process on behalf of our Board of Directors and reviewing with management and our auditors, as appropriate, our major financial risk exposures as well as risks relating to information security, competition, and regulation. The Compensation Committee is responsible for overseeing our practices and policies of employee compensation as they relate to risk management and risk-taking incentives to determine whether such compensation policies and practices are reasonably likely to have a material adverse effect on the Company. The Nominating and Corporate Governance Committee oversees the management of risks associated with our overall compliance and corporate governance practices and the independence and composition of our Board of Directors. Our Board committees provide regular reports to our Board of Directors.

#### Board Meetings
Our Board of Directors met eight times during the last fiscal year. Each Board member attended 75% or more of the aggregate number of meetings of the Board and of the committees on which he or she served, held during the portion of the fiscal year ended December 31, 2025 for which he or she was a director or committee member. Directors are encouraged, but not required, to attend each annual meeting of stockholders. All our then-serving directors attended the 2025 Annual Meeting of Stockholders.

#### Executive Sessions of the Board
As required under the Nasdaq Listing Standards, our independent directors meet periodically in scheduled executive sessions at which only independent directors are present, typically at the time of each regular Board meeting and as frequently as such independent directors deem appropriate.

#### Information Regarding Committees of the Board of Directors
Our Board of Directors has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. The following table provides membership and meeting information for each of the Board committees during last fiscal year:

\* Committee Chairperson

Below is a description of each committee of the Board of Directors. The Board has adopted written charters for each of the committees, which are available in the Investor Relations section of our website at https://investors.pulmonx.com.

#### Audit Committee
Our Board reviews the Nasdaq Listing Standards definition of independence for Audit Committee members on an annual basis and has determined that each of the members of the Audit Committee satisfies the independence requirements of the Nasdaq Listing Standards and Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Each member of the Audit Committee can read and understand fundamental financial statements in accordance with the applicable Nasdaq Listing Standards. In arriving at these determinations, our Board examined each Audit Committee member's scope of experience and the nature of her or his employment in the corporate finance sector. Our Board has also determined that Mr. Florin qualifies as an "audit committee financial expert," as defined in applicable SEC rules. Our Board made a qualitative assessment of Mr. Florin's level of knowledge and experience based on several factors, including his formal education and experience as a chief financial officer for public reporting companies.

------

#### **TABLE OF CONTENTS**
The Audit Committee was established by our Board in accordance with Section 3(a)(58)(A) of the Exchange Act to oversee the Company's corporate accounting and financial reporting processes and audits of its financial statements. For this purpose, the Audit Committee performs several functions. The principal duties and responsibilities of the Audit Committee include, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;• managing the selection, engagement terms, fees, qualifications, independence, and performance of the registered public accounting firms engaged as the Company's independent outside auditors for the purpose of preparing or issuing an audit report or performing audit services;

&nbsp;&nbsp;&nbsp;&nbsp;• approving or, as permitted, pre-approving, audit and permissible non-audit and tax services to be performed by the Company's independent outside auditors;

&nbsp;&nbsp;&nbsp;&nbsp;• setting hiring policies with respect to employees and former employees of our independent registered public accounting firm;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing audit plans, and reviewing, with management and the independent registered public accounting firm, the results of the independent audit and the quarterly reviews and any significant issues that arise regarding accounting principles and financial statement presentation;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing any reports or disclosures required by applicable law and stock exchange listing requirements;

&nbsp;&nbsp;&nbsp;&nbsp;• preparing the Audit Committee Report to be included in the Company's annual proxy statement;

&nbsp;&nbsp;&nbsp;&nbsp;• overseeing the design, implementation, organization, and performance of the Company's internal audit function;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and discussing with management and the independent registered public accounting firm the adequacy and effectiveness of our internal control over financial reporting and disclosure controls and procedures;

&nbsp;&nbsp;&nbsp;&nbsp;• helping our Board oversee the Company's legal and regulatory compliance; and

&nbsp;&nbsp;&nbsp;&nbsp;• assessing and managing risks pertaining to the financial, accounting, data privacy and cybersecurity matters of the Company and reviewing the Company's processes and policies related to such risks.

#### Report of the Audit Committee of the Board of Directors
The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2025 with management of the Company. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC. The Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountant's communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm's independence. Based on the foregoing, the Audit Committee has recommended to the Board of Directors of the Company that the audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

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

#### Compensation Committee
Our Board reviews the Nasdaq Listing Standards definition of independence for compensation committee members on an annual basis and has determined that each of the members of the Compensation Committee satisfies

------

#### **TABLE OF CONTENTS**
the independence requirements of the Nasdaq Listing Standards and Rule 10C-1 under the Exchange Act, is a "non-employee director" as defined in Rule 16b-3 promulgated under the Exchange Act, and is an "outside director" as that term is defined in Section 162(m) of the Internal Revenue Code (the "Code"). In arriving at this determination, our Board examined each Compensation Committee member's scope of experience and the nature of their prior and/or current employment.

The Compensation Committee acts on behalf of our Board to review, oversee (or make recommendation to our Board for approval of) the Company's compensation strategy, policies, plans and programs, including:

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and approving, or recommending that our Board approve, the compensation of our executive officers, including evaluating the performance of our Chief Executive Officer and, with his assistance, that of our other executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and recommending to our Board the compensation of our directors;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing the Company's practices and policies of employee compensation as they relate to risk management and risk-taking incentives;

&nbsp;&nbsp;&nbsp;&nbsp;• administering our equity awards and pension plans, bonus plans, benefit plans and other similar programs;

&nbsp;&nbsp;&nbsp;&nbsp;• adopting, amending, or terminating the Company's equity awards and pension plans, bonus plans, benefit plans and other similar programs;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and evaluating with our Board the succession plans for the Company's Chief Executive Officer and other executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and discussing with management any conflicts of interest raised by the work of a compensation consultant or advisor hired by the Committee or management and how such conflict is being addressed, and prepare any necessary disclosure in the Company's annual proxy statement in accordance with applicable law and stock exchange requirements;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and establishing general policies relating to compensation and benefits of our employees and reviewing our overall compensation philosophy; and

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and discussing with management the Company's policies and practices related to its management of human capital resources.

#### Compensation Committee Processes and Procedures
The Compensation Committee intends to meet four times a year and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with management and outside advisors. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation.

The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. If the Committee concludes that it must retain legal, accounting, or other outside advisors (including compensation consultants), it may do so and determine compensation terms for those advisors at the Company's expense. The Compensation Committee has the authority to require that any of the Company's personnel or outside advisors attend any meeting of the Compensation Committee or meet with any member of the Compensation Committee or any of its advisors. In addition, the Chairperson of the Compensation Committee has the delegated authority to act on behalf of the Committee in connection with approval of the retention of compensation consultants and outside service providers and advisors (including negotiation and execution of their engagement letters) and as may otherwise be determined by the Compensation Committee. The Compensation Committee also may form and delegate authority to one or more subcommittees consisting of one or more members of the Board (whether or not he, she or they are on the Committee) to the extent allowed under applicable law and stock exchange listing requirements.

#### **TABLE OF CONTENTS**

#### Nominating and Corporate Governance Committee
Our Board has determined that each of the members of the Nominating and Corporate Governance Committee satisfies the independence requirements of the Nasdaq Listing Standards.

The principal duties and responsibilities of the Nominating and Corporate Governance Committee include, among other things:

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

&nbsp;&nbsp;&nbsp;&nbsp;• overseeing our Board's committee structure and operations, including evaluating individual directors' interests, and prospective director independence, experience and the independence and requirements imposed by applicable law and stock exchange listing requirements and recommending to our Board annually the chairmanship and membership of each committee;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing the performance of our Board, including (together with such committees) the committees of our Board;

&nbsp;&nbsp;&nbsp;&nbsp;• instituting plans or programs for the continuing education of directors and orientation of new directors, as the committee deems appropriate;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and assessing the Company's corporate governance guidelines and stock ownership guidelines, and, as appropriate, recommending changes to our Board for its consideration;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing the processes and procedures used by the Company to provide information to our Board and its committees and the scope of such information and make recommendations to our Board and management for improvement as appropriate;

&nbsp;&nbsp;&nbsp;&nbsp;• overseeing the Company's strategy, risks, opportunities, and related public reporting with respect to environmental, social and governance matters and practices; and

&nbsp;&nbsp;&nbsp;&nbsp;• periodically reviewing and overseeing the Company's strategy, risks, opportunities, and related public reporting with respect to environmental, social, and governance matters and practices.

Our Board believes that candidates for director should have certain minimum qualifications and our Nominating and Corporate Governance Committee identifies and evaluates candidates consistent with the criteria set forth in our Corporate Governance Guidelines. These minimum qualifications include having the highest personal integrity and ethics, the ability to read and understand basic financial statements, and being older than 21 years of age. Our Board and the Nominating and Corporate Governance Committee also considers 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, diversity of personal background, demonstrated excellence in his or her field, having the ability to exercise sound business judgment, experience as a board member or executive officer of another publicly held company and having the commitment to rigorously represent the long-term interests of our stockholders. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time.

Candidates for director nominees are reviewed in the context of the current composition of the Board of Directors, the operating requirements of the Company and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee considers diversity of skill, professional experience, personal background and perspective and 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.

The Nominating and Corporate Governance Committee is responsible for reviewing the appropriate skills and characteristics required of directors and potential director candidates in the context of prevailing business conditions and existing competencies on our Board of Directors, and for making recommendations regarding the size and composition of the Board, with the objective of having a balanced and effective Board that reflects a variety of characteristics, perspectives, skills and professional experience. The Nominating and Corporate Governance Committee's review and periodic assessments of the characteristics, perspectives, skills and professional experience it seeks in the Board as a whole, and in individual directors, in connection with its review of the Board's composition, enables it to assess the effectiveness of its goal of achieving a balanced and effective board with diversity.

------

#### **TABLE OF CONTENTS**
The Nominating and Corporate Governance Committee uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board of Directors. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates' qualifications and then selects a nominee for recommendation to the Board of Directors by majority vote.

In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews these directors' service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors' independence, as well as the overall composition of the Board of the Directors and the desire to add new skill sets and expertise to the Company in light of its recent transition from a private to a public reporting company.

In the case of all director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for Nasdaq purposes, which determination is based upon applicable Nasdaq Listing Standards, applicable SEC rules and regulations and the advice of counsel, if necessary.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: Attn: Secretary, 700 Chesapeake Drive, Redwood City, California 94063. Submissions must include the full name of the proposed nominee, a description of the proposed nominee's business experience for at least the previous five years, complete biographical information, a description of the proposed nominee's qualifications as a director and a representation that the nominating stockholder is a beneficial or record holder of the Company's stock and has been a holder for at least one year. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected. For information on the requirements governing shareholder nominations for the election of directors, please refer to the section titled "Stockholder Proposals for 2027 Annual Meeting of Stockholders."

#### Stockholder Communications with The Board of Directors
Our Board of Directors believes that stockholders should have an opportunity to communicate with the Board of Directors, and efforts have been made to ensure that the views of stockholders are heard by the Board of Directors or individual directors, as applicable, and that appropriate responses are provided to stockholders in a timely manner. Stockholders wishing to communicate with the Board or an individual director may send a written communication to the Board of Directors or such director c/o Attn: Secretary, 700 Chesapeake Drive, Redwood City, California 94063. The Secretary will review each communication. The Secretary will forward such communication to the Board of Directors or to any individual director to whom the communication is addressed unless the communication contains advertisements or solicitations or is unduly hostile, threatening or similarly inappropriate, in which case the Secretary shall discard the communication.

#### Code of Business Conduct and Ethics
The Company has adopted the Pulmonx Code of Business Conduct and Ethics that applies to all officers, directors, and employees. The Code of Business Conduct and Ethics is available in the Investor Relations section of our website at investors.pulmonx.com.

#### Insider Trading Policy
We have adopted an Insider Trading Policy governing the purchase, sale, and/or other dispositions of the Company's securities by directors, officers and employees that is designed to promote compliance with insider trading laws, rules and regulations, as well as procedures designed to further the foregoing purposes. A copy of our

#### **TABLE OF CONTENTS**
insider trading policy is filed as Exhibit 19.1 to the Company's Annual Report on Form 10-K. In addition, it is the Company's intent to comply with applicable laws and regulations relating to insider trading.

#### Hedging Policy
Our Insider Trading Policy prohibits officers, directors, employees and designated consultants of the Company and its subsidiaries from purchasing our securities on margin or holding our securities in margin accounts, hedging or monetization transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds, trading in derivative securities related to our common stock or engaging in short selling of our common stock. The Insider Trading Policy is available in the Investor Relations section of our website at investors.pulmonx.com.

#### Board Composition
We believe that a Board comprised of directors with diverse skills, professional experience, personal background and perspectives contributes to overall Board effectiveness and improves Board decision making. As such, the Board and the Nominating and Corporate Governance Committee are committed to continuing to enhance the Board's composition by identifying potential director candidates with varied attributes, experiences, and perspectives. Currently, 28% of our Board self-identifies as female and 14% of our Board self-identifies as from an underrepresented community. The Nominating and Governance Committee evaluates the composition of the Board as part of the annual nomination process and assesses the effectiveness of its approach to Board composition as part of the Board and committee evaluation process.

#### Stock Ownership Policy
In an effort to further align the interests of our executive officers and non-employee directors with those of our stockholders, the Board has adopted a Stock Ownership Policy. Within five years of becoming subject to the policy, our non-employee directors are required to own or hold shares of our common stock, including any vested stock options (valued net of exercise price) and restricted stock units ("Qualifying Company Stock"), with a total value equal to three times the annual cash retainer for Board service, excluding any additional cash service retainers for serving on committees or as chairpersons. Within five years of becoming subject to the policy, an executive officer for purposes of Section 16 of the Exchange Act is required to own or hold Qualifying Company Stock with a value of one times annual base salary, except in the case of our Chief Executive Officer, who is required to own or hold Qualifying Company Stock with a value of three times annual base salary.

Neither our Amended and Restated Bylaws nor other governing documents or law require stockholder ratification of the selection of BDO as our independent registered public accounting firm. However, our Board considers the selection of the independent registered public accounting firm to be an important matter of stockholder concern and is submitting the selection of BDO for ratification by our stockholders as a matter of good corporate practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain BDO. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of us and our stockholders.

The Audit Committee and our Board believe that the continued retention of BDO as our independent registered public accounting firm for the fiscal year ending December 31, 2026 to be in the best interests of us and our stockholders. Representatives from BDO are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and are expected to be available to respond to appropriate questions.

#### Pre-Approval Policies and Procedures
The Audit Committee has procedures in place for the pre-approval of audit and non-audit services rendered by the Company's independent registered public accounting firm, BDO. The Audit Committee generally pre-approves specified services in the defined categories of audit services, audit-related services, and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee's approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee's members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

The Audit Committee has determined that the rendering of services other than audit services by BDO is compatible with maintaining the principal accountant's independence.

#### PROPOSAL NO. 3

#### NON-BINDING ADVISORY VOTE TO APPROVE THE COMPENSATION OF THE COMPANY'S NAMED EXECUTIVE OFFICERS
Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") and Section 14A of the Exchange Act, our stockholders are entitled to vote to approve, on a non-binding advisory basis, our executive compensation as disclosed in this Proxy Statement in accordance with SEC rules. As described in further detail under the heading "Executive Compensation" our executive compensation program is designed to drive and reward performance and align the compensation of our named executive officers with the long-term interests of our stockholders. Please read the compensation tables and related narrative disclosures for additional details about our executive compensation program, including information about the compensation of our named executive officers for the last fiscal year.

This proposal, commonly known as a "say-on-pay" proposal, gives our stockholders the opportunity to express their views on our executive compensation as a whole. This vote is not intended to address any specific element of compensation but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this Proxy Statement. Our Board and our Compensation Committee believe that our compensation philosophy and decisions support our key business objectives of creating value for, and promoting the interests of, our stockholders and are therefore effective in achieving our compensation program goals.

Accordingly, our Board is asking our stockholders to indicate their support for our executive compensation as described in this Proxy Statement by casting a non-binding advisory vote "FOR" the following resolution:

**RESOLVED, that the stockholders of the Company approve, on a non-binding advisory basis, the Company's executive compensation, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and the narrative discussions that accompany the compensation tables.** 

Because the vote is advisory, it is not binding on us or our Board. Nevertheless, the views expressed by our stockholders, whether through this vote or otherwise, are important to our management and our Board and, accordingly, our Board and our Compensation Committee intend to consider the results of this vote in making determinations in the future regarding our executive compensation program. Unless the Board decides to modify its policy regarding the frequency of soliciting advisory votes on the compensation of the Company's named executives, the next scheduled say-on-pay vote will be at the 2027 Annual Meeting of Shareholders.

Commencing in August of 2023 the Compensation Committee engaged Frederic W. Cook & Co., Inc. ("FW Cook") as its compensation advisor. Each year, the Compensation Committee analyzes whether the work of FW Cook as a compensation consultant raises any conflict of interest, taking into consideration the factors set forth in applicable SEC rules and the Nasdaq Listing Standards regarding compensation advisor conflicts of interest and independence. As with prior years, in connection with the Company's 2025 executive compensation determinations, the Compensation Committee concluded, based on its analysis of those factors, that the work of FW Cook and the individual compensation advisors employed by the firm as a compensation consultant to the Company is free from any conflict of interest.

To assist in determining overall compensation for 2025, FW Cook and the Compensation Committee reviewed a peer group of publicly traded companies in the life sciences industry at a stage of development, market capitalization and size comparable to the Company. The Compensation Committee believed these companies were generally comparable to the Company and that the Company competed with these companies for talent, including executive talent. In addition to the publicly available information with respect to peer group companies, FW Cook gathered competitive market data from survey data from broader custom groups of publicly traded, US-based medical device companies for the Compensation Committee's analysis of executive compensation.

For compensation decisions for executives other than our Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to it by the Chief Executive Officer. In the case of our Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee in consultation with the Board.

#### Competitive Market Review
For developing the 2025 executive compensation program, the Compensation Committee, following consultation with FW Cook, approved a peer group. In developing the peer group for 2025, the criteria that were used to identify the peer companies were financial profile, revenue, market capitalization, and current stage of product development or business activity with a goal to maintain a substantial level of year-over-year consistency in the peer group to the extent appropriate barring substantial changes in company size or business. The 15 companies in the peer group for 2025 are listed below.

#### Stockholder Engagement With Respect to Compensation Programs
We value and encourage an open dialogue with our stockholders. We strongly believe that healthy two-way communication with our stockholders is an essential aspect of a company's processes and is beneficial to our business and our company. In addition to this outreach, we have an investor relations program that is active throughout the year and includes our quarterly financial and operational update calls, post-earnings communications, investor meetings, as well as attendance and presentations at conferences. Our investor relations team is generally available to engage on investor questions and dialogue.

In 2025, we reached out to stockholders in advance of the Company's 2025 Annual Meeting of Stockholders, to discuss the matters set out in our 2025 Proxy; later in 2025 into early 2026 we again reached out to stockholders to discuss the transitions of our CEO and CFO announced in October of 2025.

*2025 Advisory Vote on Executive Compensation* 

At the Company's 2025 Annual Meeting of Stockholders, the Company's non-binding advisory vote to approve its 2024 executive compensation passed, with approximately 51% of votes cast being in favor of the resolution. This result was lower than we had hoped for, particularly after we had introduced performance-based restricted stock

units ("PSUs") into the 2025 executive compensation program in direct response to stockholder feedback. As discussed below, we have engaged in two stockholder outreach initiatives since the publication of our 2025 Proxy Statement and have gleaned some valuable insights and input from our stockholders, which we describe in summary form below.

*May 2025 Stockholder Outreach – Compensation Reported in 2025 Proxy Statement and Corporate Governance* 

After the publication of our 2025 Proxy Statement, the Compensation Committee instructed management to reach out to stockholders to better understand their concerns and priorities as well as feedback on the matters discussed in the 2025 Proxy Statement. Our team, comprised of the Company's general counsel, chief people officer, in some cases our CFO, and in most cases the chairman of our Compensation Committee, reached out to stockholders representing approximately 65% of our outstanding common stock and were able to arrange meetings with stockholders representing approximately 29% of our outstanding common stock. We undertook this stockholder outreach effort in May 2025 prior to our 2025 Annual Meeting. In addition to soliciting input on the matters in the 2025 Proxy Statement, we sought input on whether our stockholders considered that we had addressed previous stockholder input regarding our practices and policies. Although we were only able to speak to a percentage of our top investors, those discussions helped us to understand the results of the subsequent voting results of the 2025 Annual Meeting. In particular, we heard important perspectives on the use of performance stock units in our executive compensation program, the way we disclose and structure our bonus program, and some corporate governance structures. In the spirit of transparency, to which our Board of Directors and management team is committed, we will discuss each of these points in turn below.

&nbsp;&nbsp;&nbsp;&nbsp;• **Performance Stock Units**: We introduced PSUs into the executive compensation program in 2025: for executives other than the CEO, 25% of their equity grant was in PSUs and 75% was in RSUs; for the CEO, 25% was in PSUs, 25% was in stock options, and the remainder was in RSUs. Although we heard that stockholders were appreciative of our introducing performance equity into the program, we were told that there was a preference to see a higher percentage of the CEO grant in performance equity. The Company understands that perspective, and it was reflected in the initial equity grant for Glen French when he was engaged later that year as CEO. See, "Outstanding Equity Awards at December 31, 2025" below.

&nbsp;&nbsp;&nbsp;&nbsp;• **Bonus Plan Disclosure**: Company stockholders have requested that we add further visibility to the way we report our bonus plan performance in relation to the specific goals that were established at the beginning of the plan. We understand that the lack of details around the goals of the 2024 bonus plan contributed to the results of the say-on-pay vote in 2025. The Company understands that providing clarity to investors about the goals that are set for management is useful for understanding the bonus achievement we report. We are subject to the reporting requirements of a smaller reporting company, which require less detail than is required for companies that are not smaller reporting companies. However, with this Proxy Statement, in our discussion of the 2025 bonus program, we have provided further clarity as to how we structure the bonus plan and the goals established under the plan.

&nbsp;&nbsp;&nbsp;&nbsp;• **Bonus Plan Structure**: In addition to stockholder feedback for increased transparency with respect to the Company's cash bonus plan, stockholders have consistently noted that they prefer to see bonus plan objectives closely align with stockholder value, to see goals with clear objective achievement criteria, and to include a cap on overachievement. We have incorporated that input into our bonus plan designs in the past and believe the 2025 bonus plan is consistent with this approach. Among other things, the financial objectives of revenue and Adjusted EBITDA, which stockholders have identified as being closely tied to stockholder value, comprised 75% of the total target bonus opportunity for 2025. We heard input that bonus programs should have caps and that those caps should be transparent. The 2025 bonus plan included a maximum cap of 200% on the revenue objective overachievement potential, while the Adjusted EBITDA goal had a 150% overachievement feature. The plan also included strategic objectives involving the Company's key programs tied to value creation for 2025. Finally, the stockholders have consistently provided input that while the Compensation Committee has the discretion to modify plan mechanics or goals as they calculate the results of a given year, in such circumstances it is helpful to include a thorough disclosure of the Compensation Committee's rationale. With this advice in mind, the Compensation Committee calculated the results of the 2025 bonus plan strictly in accordance with the objectives and

------

mechanics established at the beginning of the year, and the Compensation Committee did not make any discretionary adjustments to the 2025 bonus plan goals established at the beginning of the year or to the final payouts. For further discussion of the annual cash performance bonus, see the section below titled "Annual Cash Performance Bonus."

&nbsp;&nbsp;&nbsp;&nbsp;• **Corporate Governance Matters**: Lastly, we have had the opportunity to hear comments from our stockholders about certain corporate governance structures that we maintain, including certain provisions of our Bylaws and our classified Board structure. What investors told us is that they understand that these structural elements are typical for companies in our industry that are of our size and stage as a public company, but that they would like to see us modify those elements in the future. For now, the Company is confident that these elements are appropriate for our Company and in the best interest of stockholders at this stage in the Company's development. Management and the Nominating and Corporate Governance Committee of our Board continue to benchmark peer company practices and seek third party expert advice on these matters and will continue to assess the most appropriate corporate governance practices and structures for the Company.

*Stockholder Outreach Beginning in October 2025 - CEO and CFO Transition* 

In October of 2025, the company announced that (i) Steve Williamson had resigned as Chief Executive Officer and that Glen French, who was previously Chief Executive Officer of the Company and who was an ongoing member of our Board of Directors, was returning to that role, and (ii) that Mehul Joshi had resigned as Chief Financial Officer and that Derrick Sung, who had previously served as CFO of the Company, was joining the Company as Chief Operating Officer and Chief Financial Officer. After this executive transition was announced, a similar team to the one described above, including Rich Ferrari, the Chairman of our Compensation Committee, reached out to stockholder representing approximately 47% of our outstanding common stock and were able to engage with stockholders representing approximately 30% of the Company's outstanding common stock.

In these conversations we heard feedback that investors were generally pleased that we had included performance-based equity awards as part of the sign-on package for each of Messrs. French and Sung. Investors generally voiced support for the executive transition and enthusiasm for seeing what the new leadership can achieve. Consistent with past conversations with investors, there was a clear message to continue to work to align executive compensation with stockholder interests.

*Report to Board Regarding Stockholder Outreach* 

After both of these stockholder outreach initiatives, Mr. Ferrari and management provided a report about the stockholder feedback and input to the Compensation Committee and the Nominating and the Corporate Governance Committee, and through such committees, to the full Board of Directors. Both committees were grateful for the engagement of the stockholders and continue to consider such feedback in their determinations about executive compensation and corporate governance, respectively. We hold a non-binding advisory vote on our executive compensation annually and we look forward to continued engagement with our stockholders on these important issues.

#### Base Salary
Base salaries are designed to provide our NEOs with a reasonable degree of financial certainty and stability, which is important for the recruitment and retention of high-quality executives. Our Compensation Committee annually reviews and determines the base salaries of NEOs and evaluates the base salaries of new hire NEOs at the time of hire. In early 2025, our Compensation Committee determined to increase the base salaries of our then-employed named executive officers by between 3% and 4%, consistent with overall merit increases to our management team. Additionally, Mr. French rejoined the Company in October 2025 and Mr. Sung rejoined the Company in November 2025. Their initial base salaries were established with reference to their role, their experience and peer company compensation data.

#### Annual Cash Performance Bonus
In addition to their base salaries, our NEOs are eligible to receive performance-based cash bonuses, which are designed to provide appropriate incentives to our executives to achieve defined performance goals and to reward our executives for individual contributions towards such goals. The performance-based cash bonus each executive

------

#### **TABLE OF CONTENTS**
officer is eligible to receive is generally based on the extent to which we achieve the corporate goals that our Board of Directors or the Compensation Committee establishes at the beginning of each year. All final bonus payments to our executive officers are determined by the Compensation Committee. The actual bonuses awarded in any year, if any, may be more or less than the target, depending on the achievement of corporate objectives and individual performance.

Bonuses are set based on a percentage of the executive's base salary and are expected to be paid annually in the first quarter of the year following the performance year. The 2025 target bonus levels for our NEOs were as follows: 75% for Mr. Williamson, who was serving as Chief Executive Officer at the time that target bonuses were set, 50% for Mr. Joshi, who was serving as our Chief Financial Officer, and 45% for Mr. Lehman, our General Counsel, respectively. Messrs. Williamson and Joshi did not receive any payout from the 2025 bonus due to their departure from the Company in December 2025. Messrs. French and Sung joined the Company as executives in the fourth quarter of 2025 and were not eligible for a bonus for 2025.

In January 2025, the Compensation Committee, in consultation with our Board, established the corporate performance goals for the 2025 bonus plan with 75% focused on financial objectives, comprised of a revenue objective representing 65% of the target bonus opportunity, and an Adjusted EBITDA<sup>1</sup> target representing 10%. Objectives involving various strategic initiatives represented the remaining 25% of the target bonus opportunity. The strategic initiatives included objectives related to supporting scaling treating centers, patient education and engagement, and progress of our clinical studies. All of the corporate performance goals included a minimum threshold and discounting feature applicable to achievement below 100% of the revenue target and overachievement potential for performance beyond the target. The maximum potential achievement was capped at 200% for the revenue target and capped at 150% for all other performance goals. In February 2026, the Compensation Committee assessed our achievement of the corporate performance targets for 2025 and determined that (1) the revenue target had not been achieved above the minimum threshold resulting in no payment with respect to that portion of the bonus plan, (2) the Adjusted EBITDA target had been overachieved due to cost discipline during the year resulting in a maximum (150%) payout with respect to that 10% portion of the bonus, and (3) with respect to the objectives related to strategic initiatives, only the objective related to the progress of our clinical studies, which represented 10% out of the 25% weighting associated with the strategic goals was partially achieved, at the level of 5.6%, resulting in a 56% payout with respect to that portion of the bonus, with the total of such achievement levels resulting in a 2025 bonus plan payout of 20.6% of the target bonus opportunity.

*Equity Compensation* 

*Introduction of Performance Awards in 2025* 

For the 2025 executive compensation program, the Compensation Committee, with the advice of our compensation consultant, considered a variety of approaches to performance equity, including the most appropriate performance metrics and vesting structure, as well as the optimal timing for introducing such elements into our executive compensation program. The Compensation Committee determined, after substantial analysis, that it was in the best interests of the Company and our stockholders to add PSUs to the Company's executive compensation

<sup>1</sup> Refer to our earnings press release for the year and quarter ended December 31, 2025 filed as Exhibit 99.1 to our Current Report on Form 8-K filed with the SEC on March 4, 2026. We defined Adjusted EBITDA as GAAP net loss adjusted for depreciation and amortization, stock-based compensation, interest income or expense, net, and income taxes.

#### **TABLE OF CONTENTS**
program commencing with 2025. The Compensation Committee utilized PSUs both for the annual equity compensation grants to the Company's executives and also used PSUs for the initial grants made to Mr. French and Mr. Sung later in the year.

The 2025 annual equity compensation grants to Company executives other than the CEO were comprised of 25% PSUs and 75% RSUs, and the equity compensation grant to Mr. Williamson was comprised of 25% PSUs, 25% stock options, and 50% RSUs. Payouts for the Company's 2025 annual equity compensation grant PSUs will be determined based on the Company's consolidated cumulative revenue over a two-year performance period, and any such PSUs earned at the end of the performance period will vest in equal installments over the following four quarters. The Compensation Committee considered various potential performance features for the PSUs and determined that a cumulative consolidated revenue goal is a measurement metric that, for a company at our stage of growth, closely aligns the interests of the Company's executives with those of our stockholders. The two-year period of measurement also is consistent with stockholder focus on growth during that period and, considering the Company's maturity and growth assumptions, avoids the complications of forecasting for longer durations. The Compensation Committee also considered that this is the first introduction of PSUs into the Company's executive compensation program and determined this performance metric to be one that the stockholders and the executives can clearly measure and tie to the Company's performance. The Compensation Committee believes these performance features are aligned with stockholder feedback and interests.

The Compensation Committee, working with the Company's compensation consultants, granted PSUs with a somewhat different structure to Mr. French and Mr. Sung in 2025 in connection with their joining the Company as executives. Their PSUs vest upon meeting the two conditions: (a) our common stock achieving an average closing price of $4.00 per share over sixty (60) consecutive trading days, and (b) a service-based vesting schedule, which is met with respect to 33% of the award on the first anniversary of the grant date of December 1, 2025, with the remainder vesting in eight subsequent equal quarterly installments, subject to continued service. The Compensation Committee considered this structure appropriate for the context of attracting and motivating new senior executives in a manner that is directly aligned with stockholder value.

*2025 Equity Awards* 

The Compensation Committee believes that stock options, which only have value if the Company experiences an increase in its stock price after the date of grant, and restricted stock units, both time-based and performance-based, the value of which is intrinsically linked to the value of the Company's stock, align the interests of our executives with those of our stockholders.

For 2025, the Company granted Mr. Williamson (i) 181,696 RSUs, vesting in equal quarterly installments over the subsequent four-year period commencing March 3, 2025, (ii) 90,848 PSUs vesting in the manner and in accordance with the terms described above, and (iii) a nonstatutory stock option to purchase 128,395 shares of the Company's common stock, vesting in equal monthly installments over the subsequent four-year period commencing March 3, 2025. The Company granted Mr. Joshi (i) 108,000 RSUs, vesting in equal quarterly installments over the subsequent four-year period commencing March 3, 2025 and (ii) 36,000 PSUs. The Company granted Mr. Lehman (i) 108,000 RSUs, vesting in equal quarterly installments over the subsequent four-year period commencing March 3, 2025 and (ii) 36,000 PSUs.

In connection with the appointment of Mr. French as our President and Chief Executive Officer in October of 2025, the Company granted Mr. French (i) 1,200,000 RSUs, vesting in equal quarterly installments over a three-year period following December 1, 2025 subject to Mr. French's continued service, and (ii) 800,000 PSUs, which vest upon meeting the following two conditions: (a) our common stock achieving an average closing price of $4.00 per share over sixty (60) consecutive trading days, and (b) a service-based vesting schedule, which is met with respect to 33% of the award on the first anniversary of the grant date of December 1, 2025, with the remainder vesting in eight subsequent equal quarterly installments ((i) and (ii) collectively referred to as the "French Initial Equity Grants").

In connection with the appointment of Mr. Sung as our Chief Operating Officer and Chief Financial Officer in October of 2025, the Company granted Mr. Sung (i) 1,200,000 RSUs, 25% of which vests on the first anniversary of the grant date of December 1, 2025, with the remainder vesting in equal quarterly installments over the three-year period following December 1, 2026, in each case subject to Mr. Sung's continued service, and (ii) 400,000 PSUs, which vest based on the same conditions as Mr. French's PSUs ((i) and (ii) collectively referred to as the "Sung Initial Equity Grants"). The Sung Initial Equity Grants were issued pursuant to the Company's 2025 Inducement Plan, adopted by the Board of Directors on November 21, 2025, and were granted as a material inducement to

#### Severance and Change in Control Plan
In September 2020, we adopted a Severance and Change in Control Plan ("CIC Plan") that provides severance and change in control benefits to each of our executive officers, including our NEOs, and certain other participants, under the conditions described below.

Pursuant to the terms of the CIC Plan, upon a termination other than for "cause," death, or "disability," or upon a resignation for "good reason" (each as defined in the CIC Plan, and collectively, a qualifying termination), in each case that occurs during the period commencing immediately prior to the closing of a "change in control" (as defined in the CIC Plan) and ending 12 months following such change in control, the participant will be entitled to receive (i) a cash payment equal to 18 months of base salary, in the case of the CEO, or 12 months of base salary, in the case of other executive officers; (ii) a cash payment equal to the participant's target annual bonus; (iii) reimbursement of COBRA premiums for the duration of the severance period; and (iv) acceleration of vesting (and, if applicable, exercisability) of 100% of then-unvested time-based equity awards held by such employee. Upon a qualifying termination that does not occur in connection with a change of control, the participant will be entitled to receive (i) cash payments equal to 12 months of base salary, in the case of the CEO, and nine months of base salary, in the case of other executive officers; and (ii) reimbursement of COBRA premiums for the duration of the severance period. All benefits under the CIC Plan are subject to the participant signing a general release of claims.

#### Incentive Compensation Recoupment Policy
As a public company, if we are required to restate our financial results due to our material noncompliance with any financial reporting requirements under the federal securities laws as a result of misconduct, our Chief Executive Officer and our Chief Financial Officer may be legally required to reimburse us for any bonus or other incentive-based or equity-based compensation they receive in accordance with the provisions of section 304 of the Sarbanes-Oxley Act of 2002, as amended. Additionally, in an effort to further align the interests of our executive officers with those of our stockholders, we have implemented a Dodd-Frank Act-compliant clawback policy, as required by SEC rules.

#### **TABLE OF CONTENTS**

#### Employee Benefit Plans
Our NEOs participate in our health and welfare plans on the same basis as other employees.

Our NEOs are also eligible to participate in our 401(k) plan on the same basis as other employees. Eligible employees may defer compensation pursuant to the terms of the 401(k) plan up to certain limits imposed by the Code. We may make matching and discretionary contributions to the 401(k) plan but have not done so to date. Employees are immediately and fully vested in their own contributions. The 401(k) plan is intended to be qualified under Section 401(a) of the Code, with the related trust intended to be tax exempt under Section 501(a) of the Code.

#### Equity Compensation Plans
We believe that our ability to grant equity-based awards is a valuable and necessary compensation tool that aligns the long-term financial interests of our employees, directors, and consultants with the financial interests of our stockholders. In addition, we believe that our ability to grant options, restricted stock units, and other equity-based awards helps us to attract, retain and motivate employees, directors, and consultants, and encourages them to devote their best efforts to our business and financial success.

We currently maintain five equity compensation plans: our Amended and Restated 2010 Stock Plan (the "2010 Plan"), our 2020 Stock Plan (the "2020 Stock Plan"), our 2020 Equity Incentive Plan (the "2020 Plan"), and our 2020 Employee Stock Purchase Plan (the "2020 ESPP"), which have all been approved by stockholders. The 2010 Plan expired in February 2020 and the 2020 Stock Plan terminated in September 2020 in connection with our IPO.

#### Analysis of the Information Presented in the Pay versus Performance Table
We generally seek to incentivize long-term performance and therefore do not specifically align our performance measures with "compensation actually paid" (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, we are providing the following descriptions of the relationships between information presented in the Pay Versus Performance table.

#### Compensation Actually Paid and Net Income (Loss)
Our company has not historically looked to net income (loss) as a performance measure for our executive compensation program. Our net income (loss) was $(60.84) million in 2023, $(56.39) million in 2024, and $(54.00) million in 2025.

#### Compensation Actually Paid and Cumulative TSR
The chart below shows the relationship between the compensation actually paid to Messrs. French and Williamson and the average compensation actually paid to our other NEOs, on the one hand, to our cumulative TSR over the two years presented in the table, on the other.

All information provided above under the "Pay Versus Performance" heading will not be deemed to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent the Company specifically incorporates such information by reference.

#### Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Nonpublic Information
From time to time, the Company grants stock options, restricted stock units, and performance stock units (collectively, "Equity Awards") to its employees, including the named executive officers. Our practice is to grant new-hire Equity Awards on the first business day of the third month of each quarter (the "Quarterly Grant Date") that falls on or after a new hire's employment start date and to grant annual refresh Equity Awards to employees who are not executives on the Quarterly Grant Date in the first quarter of each fiscal year. Refresh grants for executives of the Company are typically approved at a meeting of the Compensation Committee occurring in such first quarter and are granted effective as of the Quarterly Grant Date.

Also, non-employee directors may receive automatic grants of initial and annual Equity Awards on the Quarterly Grant Date immediately following his or her initial election or appointment to our Board or the business day following the Annual Meeting of Stockholders, respectively, pursuant to the Non-Employee Director Compensation Policy, as further described under the heading, "Director Compensation—Non-Employee Director Compensation Policy" below. The Company does not otherwise maintain any written policies on the timing of

------

#### **TABLE OF CONTENTS**
Equity Awards. Because the Compensation Committee has a practice of generally granting Equity Awards on the Quarterly Grant Date after Equity Awards are approved, the Compensation Committee generally does not take MNPI into account when determining the timing of awards and it does not seek to time the award of Equity Awards in relation to the Company's public disclosure of MNPI. The Company has not timed the release of MNPI for the purpose of affecting the value of executive compensation.

On January 1, 2026, the number of shares available for issuance under the 2020 ESPP automatically increased by 416,736 shares.

&nbsp;&nbsp;&nbsp;&nbsp;(3) This amount includes inducement awards granted pursuant to the Company's 2025 Inducement Plan, as well as inducement awards granted to Mr. Williamson and Mr. Joshi outside of the Company's 2020 Equity Incentive Plan. In each case, these awards were granted pursuant to the "inducement" grant exception under Nasdaq Listing Rule 5635(c)(4), which were approved by the Compensation Committee of the Board of Directors. Please see Part II, Item 8 titled "Financial Statements and Supplementary Data" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, including Note 10, "Stockholders' Equity" of the Notes to Consolidated Financial Statements, for further information regarding our equity compensation plans and awards.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Amounts shown in this column do not reflect dollar amounts actually received by our non-employee directors.

We currently reimburse our directors for their reasonable out-of-pocket expenses in connection with attending Board of Directors and Board committee meetings. From time to time, we have granted stock options and restricted stock unit awards to certain of our non-employee directors as compensation for their services.

In May 2025, our Board approved restricted stock unit awards for 37,153 shares of common stock to each of Messrs. Burns, Ferrari, Florin, French and Mead and Mses. Garinois-Melenikiotou and Sullivan, effective June 2, 2025. All of the restricted stock units will vest on the earlier of the one-year anniversary of the date of grant or on the date of the next annual meeting of stockholders, subject to the non-employee director's continuous service through such vesting date. Such restricted stock units are otherwise subject to the terms of the 2020 Plan and our standard form of restricted stock unit award agreement.

#### Non-Employee Director Compensation Policy
Our non-employee directors are eligible to receive equity and cash compensation for service on our Board and Board committees pursuant to our non-employee director compensation policy (the "Non-Employee Director Compensation Policy"). Our Non-Employee Director Compensation Policy was last amended in December 2023 and in August 2025, as described below.

------

#### **TABLE OF CONTENTS**

#### Equity Compensation
Equity awards are granted under the 2020 Plan or any successor equity incentive plan. All stock options granted under the Non-Employee Director Compensation Policy will be nonstatutory stock options, with a term of ten years from the date of grant (subject to earlier termination upon a termination of the non-employee director's continuous service) and an exercise price per share equal to 100% of the fair market value of a share of our common stock on the date of grant.

*Initial Equity Grant. Each non-employee director who is elected or appointed to our Board of Directors for the first time on or after the effective date of the Non-Employee Director Compensation Policy will be granted, at the discretion of the Board, either, or a combination of (i) an option to purchase a number of shares of our common stock (the "Initial Stock Option Grant") or (ii) restricted stock units (the "Initial RSU Grant") with an aggregate value of an amount equal to the pro-rata value of the Annual Equity Grant (as defined below) granted to directors at the immediately previous annual meeting of stockholders, based on the month in which the new non-employee director commences service on the Board (based on the Black-Scholes pricing method for option grants) on the Quarterly Grant Date immediately following his or her initial election or appointment to our Board and a per-share exercise price based on the closing price of our common stock on Nasdaq on the date of grant (the "Initial Equity Grant"). Such Initial Equity Grant will be made on the Quarterly Grant Date immediately following the date of his or her initial election or appointment to the Board. The Initial Stock Option Grant will vest in equal monthly installments on the same, pro-rated, vesting schedule as the Annual Equity Grant on the one-month anniversary of the date of grant and each month thereafter on the same day of the month as the grant date, subject to the non-employee director's continuous service through each vesting date, such that the Initial Stock Option Grant will be fully vested on the date of the next annual meeting of stockholders or the same day of the month as the initial stock option grant date in the month when the annual meeting of stockholders is held, whichever is earlier. In the case of the Initial RSU Grant, all of the Initial RSU grant will be fully vested on the date of the next annual meeting of stockholders or the same day of the month as the initial stock option grant date in the month when the annual meeting of stockholders is held, whichever is earlier subject to the non-employee director's continuous service through each vesting date.* 

*Annual Equity Grant. With respect to each annual meeting following the applicable non-employee director's Initial Equity Grant, each person who continues to serve as a non-employee director following such annual meeting, will be granted, at the discretion of the Board, either, or a combination of (i) an option to purchase a number of shares of our common stock (the "Annual Stock Option Grant") or (ii) restricted stock units (the "Annual RSU Grant", and the Annual Stock Option Grant and the Annual RSU Grant, alternatively or collectively, the "Annual Equity Grant") with an aggregate value of $125,000 (based on the Black-Scholes pricing method for option grants) on the Quarterly Grant Date (or, starting in August 2025, on the first business day) immediately following the date of such meeting and a per-share exercise price based on the closing price of our common stock on Nasdaq on the date of grant. In the case of the Annual Stock Option Grant, one-twelfth of the shares will vest on the one-month anniversary of the date of grant and each month thereafter on the same day of the month as the grant date (and if there is no corresponding day, on the last day of the month), subject to the non-employee director's continuous service through each vesting date. In the case of the Annual RSU Grant, all of the restricted stock units will vest on the earlier of the one-year anniversary of the date of grant or on the date of the next annual meeting of stockholders, subject to the non-employee director's continuous service through such vesting date.* 

*Change in Control. Notwithstanding the above, for each non-employee director who remains in continuous service until immediately prior to the closing of a change in control, any unvested shares subject to his or her then-outstanding equity awards will become fully vested and exercisable immediately prior to the closing of such change in control.*

All annual cash retainers will be vested upon payment.

#### Expenses
We will also reimburse each non-employee director for all ordinary, necessary, and reasonable out-of-pocket travel expenses incurred by the non-employee director in attending in person and participating in meetings of our Board or any committee thereof and any meetings of our stockholders, provided the non-employee director timely submits appropriate documentation substantiating such expenses in accordance with our travel and expense policy, as in effect at the time.

#### TRANSACTIONS WITH RELATED PERSONS AND INDEMNIFICATION

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

#### Related-Person Transactions Policy and Procedures
In September 2020, the Company adopted a written Related-Person Transactions Policy that sets forth the Company's policies and procedures regarding the identification, review, consideration and approval or ratification of "related-persons transactions." For purposes of the Company's policy only, a "related-person transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which the Company and any "related person" are participants involving an amount that exceeds $120,000. Transactions involving compensation for services provided to the Company as an employee, director, consultant or similar capacity by a related person are not covered by this policy. A related person is any executive officer, director, or more than 5% stockholder of the Company, including any of their immediate family members, and any entity owned or controlled by such persons.

Under the policy, where a transaction has been identified as a related-person transaction, management must present information regarding the proposed related-person transaction to the Audit Committee (or, where Audit Committee approval would be inappropriate, to another independent body of the Board) for consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to the Company of the transaction and whether any alternative transactions were available. To identify related-person transactions in advance, we rely on information supplied by our executive officers, directors and certain significant stockholders. In considering related-person transactions, the Committee takes into account the relevant available facts and circumstances including, but not limited to (a) the risks, costs and benefits to the Company, (b) the impact on a director's independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated, (c) the terms of the transaction, (d) the availability of other sources for comparable services or products and (e) the terms available to or from, as the case may be, unrelated third parties or to or from employees generally. In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberations and approval. The policy requires that, in determining whether to approve, ratify or reject a related-person transaction, the Committee consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, the best interests of the Company and its stockholders, as the Committee determines in the good faith exercise of its discretion.
