SEC Form DEF 14A filed by Pulmonx Corporation

You are cordially invited to attend the 2026 Annual Meeting of Stockholders (the “Annual Meeting”) of Pulmonx Corporation, a Delaware corporation (the “Company”). The Annual Meeting will be held on Thursday, June 4, 2026 at 8:00 a.m. Pacific Daylight Time exclusively via the Internet at http://www.virtualshareholdermeeting.com/LUNG2026, or any adjournments or postponements thereof, for the following purposes, as more fully described in the accompanying Proxy Statement:

Our Board of Directors has fixed the close of business on April 7, 2026 as the record date for the determination of stockholders entitled to notice of, and to vote at, the Annual Meeting or any adjournments or postponements thereof. The accompanying proxy materials include instructions on how to attend the Annual Meeting and how you may vote your shares.

The Annual Meeting will be held virtually through a live webcast. You will be able to attend the Annual Meeting, submit questions and vote during the live webcast by visiting http://www.virtualshareholdermeeting.com/LUNG2026 and entering the 16-digit control number on your Notice of Internet Availability of Proxy Materials, proxy card, or on the instructions that accompanied your proxy materials. Even if you plan on attending the Annual Meeting, we encourage you to vote your shares in advance to ensure that your vote will be represented at the Annual Meeting.

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.

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 [email protected].

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.

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,

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.

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 [email protected] to schedule an appointment.

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.

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?”

You may submit a proxy by telephone, via the Internet or by mail.

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?”

There are three matters scheduled for a vote at 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 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 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.

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.

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.

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.

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.

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

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.

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.

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:

Your most current proxy is the one that is counted.

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.

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.

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.

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

The 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.

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.

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.

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.

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.

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.

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.

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.

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:

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.

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.

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:

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.

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

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:

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.

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:

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.

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.”

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.

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. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website.

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

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.

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.

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.

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.

BDO USA, LLP (“BDO”) currently serves as our independent registered public accounting firm. After consideration of the firm’s qualifications and past performance, the Audit Committee has selected BDO as our independent registered public accounting firm for the fiscal year ending December 31, 2026. BDO has served as our independent registered public accounting firm since 2011.

In accordance with the rules of the SEC and the Audit Committee’s charter, the Audit Committee is directly responsible for the selection, appointment, compensation, retention and oversight of the Company’s independent registered public accounting firm. 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.

The following table represents aggregate fees billed by BDO to us for the fiscal years ended December 31, 2025 and 2024.

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.

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:

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.

The following table sets forth certain information regarding the ownership of our common stock as of March 15, 2026 by: (i) each director and nominee for director; (ii) each of the named executive officers named in the Summary Compensation Table; (iii) all executive officers and directors of the Company as a group; and (iv) all those known by us to be beneficial owners of more than five percent of our common stock.

This table is based upon information supplied by officers and directors as well as Schedules 13G or 13D filed with the SEC by beneficial owners of more than five percent of our common stock.

We are a “smaller reporting company” under Item 10 of Regulation S-K promulgated under the Exchange Act and the following compensation disclosure is intended to comply with the requirements applicable to smaller reporting companies. Although the rules allow us to provide less detail about our executive compensation program than companies that are not smaller reporting companies, our Compensation Committee is committed to providing the information necessary to help stockholders understand its executive compensation-related decisions. Accordingly, this section includes supplemental narratives that describe our 2025 compensation program for our named executive officers (our “NEOs”).

Our named executive officers for the year ended December 31, 2025 are as follows:

The following table summarizes our executive compensation practices to highlight both the responsible practices we have implemented and the practices we have avoided to best serve our stockholders’ long-term interests.

The following table provides information regarding compensation awarded to or paid to, or earned by, our NEOs during the fiscal years ended December 31, 2025 and 2024.

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.

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.

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.

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.

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.

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.

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 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.

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

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 EBITDA¹ 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.

The 2025 corporate bonus achievement levels were used to determine the bonuses of our NEOs. Annual bonus amounts paid to our NEOs are set forth above in “Non-Equity Incentive Plan Compensation” columns of the “Summary Compensation Table for Fiscal 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

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.

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.

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

Mr. Sung’s entry into employment with the Company within the meaning of Rule 5635(c)(4) of the Nasdaq Listing Rules. In accordance with Mr. Sung’s offer letter, he is not eligible for a further grant of Company equity awards for the four (4) calendar years subsequent to December 1, 2025.

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.

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.

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.

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. Following our IPO, we have only granted stock options, restricted stock units, performance stock units, and issued shares of our common stock pursuant to the 2020 Plan and the 2020 ESPP, and no additional issuances, grants or awards will be made pursuant to the 2010 Plan and 2020 Stock Plan.

Our Board of Directors also adopted the Pulmonx Corporation 2025 Inducement Plan (the “2025 Inducement Plan”) on November 21, 2025, without stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules. The 2025 Inducement Plan is exclusively for grants of equity compensation for newly hired employees as a material inducement of their joining the Company. Mr. Sung’s equity grants were made pursuant to the 2025 Inducement Plan in December 2025, see the section above titled “—Equity Awards.”

The following table shows for fiscal year ended December 31, 2025, certain information regarding outstanding equity awards at fiscal year end for our NEOs. For a description of vesting accelerations applicable to equity awards held by our NEOs, see the section above titled “—Severance and Change in Control Plan.”

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.

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.

The following table provides certain information with respect to all our equity compensation plans in effect as of December 31, 2025.
