PROXY STATEMENT QUESTIONS AND ANSWERS

Why am I receiving these proxy materials?

The Board of Directors (the “Board”) of AN2 Therapeutics, Inc., a Delaware corporation (“AN2 Therapeutics,” the “Company,” “we,” “us,” or “our”), has made these proxy materials available to you on the internet or, upon your request, by delivering printed versions of these materials to you by mail, in connection with the solicitation of proxies for use at our 2023 Annual Meeting of Stockholders (the “Annual Meeting”). The Board is soliciting your proxy to vote at the Annual Meeting, including at any adjournments or postponements of the meeting. You are invited to attend the Annual Meeting in person to vote on the proposals described in this proxy statement (the “Proxy Statement”). However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card or voting instruction form, or follow the instructions below to submit your proxy over the telephone or through the internet.

Why did I receive a one-page notice in the mail regarding the internet availability of proxy materials instead of a full set of printed proxy materials?

Pursuant to the “notice and access” rules adopted by the SEC, we have elected to provide stockholders access to our proxy materials over the internet. Accordingly, on or about April 29, 2023, we will mail a Notice of Internet Availability of Proxy Materials (the “Notice”) to all of our stockholders as of April 19, 2023 (the “Record Date”). The Notice includes instructions on how to access our proxy materials over the internet and how to request a printed copy of these materials. Internet distribution of our proxy materials is designed to expedite receipt by stockholders, lower the cost of the Annual Meeting and conserve natural resources. However, if you would prefer to receive paper copies of proxy materials, please follow the instructions included in the Notice.

What is the purpose of the Annual Meeting?

For stockholders to vote on the following proposals to:

•

elect the nominees Kabeer Aziz, Gilbert Lynn Marks, M.D., and Rob Readnour, Ph.D. as Class I directors;

•

ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; and

•

transact any other business as may properly come before the Annual Meeting.

How does the Board recommend I vote on these proposals?

The Board recommends that you vote:

•

FOR the election of Kabeer Aziz, Gilbert Lynn Marks, M.D., and Rob Readnour, Ph.D. as Class I directors; and

•

FOR the ratification of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.

Who is entitled to vote at the Annual Meeting?

Holders of AN2 Therapeutics common stock at the close of business on the Record Date are entitled to receive the Notice and to vote their shares at the Annual Meeting. As of the Record Date, there were 19,426,452 shares of common stock outstanding and entitled to vote at the Annual Meeting.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

If your shares are registered directly in your name with AN2 Therapeutic’s transfer agent, American Stock Transfer & Trust Co., you are considered the “stockholder of record” with respect to those shares, and the Notice was sent directly to you by the Company.

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the “beneficial owner” of shares held in street name. The Notice and, upon your request, the proxy materials have been forwarded to you by your broker, bank or other nominee who is considered, with respect to those shares, the stockholder of record. As the

beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote your shares by following their instructions for voting.

How can I vote my shares?

The instructions for accessing proxy materials and voting can be found in the Notice that you received either by mail or e-mail. In order to access proxy materials and vote, you will need the control number provided on the Notice. There are three ways a stockholder of record can vote:

(1)

By Internet: You may vote over the internet by following the instructions provided in the Notice or if you requested printed copies of proxy materials, the instructions provided in the proxy card.

(2)

By Telephone: You can vote by telephone by following the instructions in the Notice or if you requested printed copies of proxy materials, the instructions provided in the proxy card.

(3)

By Mail: If you requested printed copies of proxy materials, you can vote by mailing your proxy card as described in the proxy materials.

In order to be counted, proxies submitted by telephone or internet must be received by 11:59 p.m., Pacific Time, on June 6, 2023. If you vote by telephone or internet, you do not need to return your proxy card or voting instruction card.

If you are a beneficial owner of shares held of record by a broker, bank or other nominee, you may receive a Notice or a voting instruction card from your broker, bank or other nominee. If you receive a voting instruction card from your broker, bank or other nominee, you must follow these voting instructions in order to instruct your broker, bank or other nominee on how to vote your shares. The availability of telephone or internet voting will depend on the voting process of your broker, bank or other nominee. If you are a beneficial owner, you may not vote your shares in person at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

All shares that have been properly voted and not revoked will be cast as votes at the Annual Meeting.

What happens if I decide to attend the Annual Meeting, but I have already voted or submitted a proxy covering my shares?

You may still attend the Annual Meeting. Please be aware that attendance at the Annual Meeting will not, by itself, revoke a proxy.

Where will the Annual Meeting be held?

The Annual Meeting will be held at the offices of the Company at 1800 El Camino Real, Suite D, Menlo Park, California 94027.

What can I do if I change my mind after I vote my shares?

If you are a stockholder of record, you can change your vote or revoke your proxy before it is exercised by:

•

written notice to the Corporate Secretary of the Company;

•

timely delivery of a valid, later-dated proxy or a later-dated vote on the internet; or

•

voting in person at the virtual Annual Meeting, however, simply attending the meeting will not, by itself, revoke your proxy.

If you are a beneficial owner of shares, you should follow the instructions of your bank, broker or other nominee to change or revoke your voting instructions. You may also vote in person at the Annual Meeting if you obtain a legal proxy as described in the answer to the previous question.

What shares can I vote?

You can vote all shares that you owned on the Record Date. These shares include (1) shares held directly in your name as the stockholder of record, and (2) shares held for you as the beneficial owner through a broker, bank or other nominee.

Is there a list of stockholders entitled to vote at the Annual Meeting?

The names of stockholders of record entitled to vote at the Annual Meeting will be available for ten days prior to the Annual Meeting for any purpose germane to the Annual Meeting, between the hours of 9:30 a.m. and 4:30 p.m., Pacific Time, at our principal executive offices at 1800 El Camino Real, Suite D, Menlo Park, California, 94027, by contacting the Corporate Secretary of the Company.

How are votes counted? 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?

Each holder of common stock is entitled to one vote per share of common stock on each matter properly brought before the Annual Meeting.

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the Internet or by attending the Annual Meeting, your shares will not be voted. If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of each of the three nominees for director (Proposal No. 1) and “For” the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm (Proposal No. 2). If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

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

If you are a beneficial owner of shares held in street name, your bank, broker or other nominee may under certain circumstances vote your shares if you do not timely instruct your bank, broker or other nominee how to vote your shares. Under the rules of the New York Stock Exchange (“NYSE”), banks, brokers and other nominees that are subject to NYSE rules can vote your “uninstructed” shares with respect to any matters considered to be routine matters under NYSE rules, but cannot vote such shares on non-routine matters. If you do not timely provide voting instructions to your bank, broker or other nominee to vote your shares, your bank, broker or other nominee may, on routine matters, either vote your shares or leave your shares unvoted. The election of directors (Proposal No. 1) is a non-routine matter. The ratification of the selection of our independent registered public accounting firm (Proposal No. 2) is a routine matter. We encourage you to provide voting instructions to your bank, broker or other nominee. This ensures that your shares will be voted at the Annual Meeting according to your instructions. You should receive directions from your bank, broker or other nominee about how to submit your proxy to them at the time you receive this proxy statement.

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

How will abstentions and broker non-votes be treated at the Annual Meeting?

An abstention represents a stockholder’s affirmative choice to decline to vote on a proposal. If a stockholder indicates on its proxy card that it wishes to abstain from voting its shares, or if a broker, bank or other nominee holding its customers’ shares of record causes abstentions to be recorded for shares, these shares will be considered present and entitled to vote at the Annual Meeting. As a result, abstentions will be counted for purposes of determining the presence or absence of a quorum and will also count as votes against a proposal in cases where approval of the proposal requires the affirmative vote of a majority of the shares present and entitled to vote at the Annual Meeting (e.g., Proposal No. 2). However, because the outcome of Proposal No. 1 (election of directors) will be determined by a plurality vote, abstentions will have no impact on the outcome of such proposal as long as a quorum exists.

A broker non-vote occurs when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker, bank or other nominee does not have discretionary voting power with respect to such proposal and has not received voting instructions from the beneficial owner of the shares. Broker non-votes will be counted for purposes of calculating whether a quorum is present at the Annual Meeting but will not be counted for purposes of determining the number of votes cast. Therefore, a broker non-vote will make a quorum more readily attainable but will not otherwise affect the outcome of the vote on any proposal.

How many votes are required to approve the proposals being voted upon at the Annual Meeting?

The presence of the holders of a majority of the outstanding shares of common stock entitled to vote at the Annual Meeting, present in person or represented by proxy, is necessary to constitute a quorum. Assuming there is a proper quorum of shares represented at the Annual Meeting, the voting requirements for approval of the proposals at the Annual Meeting are as follows:


Proposal	Vote Required	Effect of Abstentions	Effect of Broker Non-Votes
Election of directors	The three nominees receiving the most “For” votes by the holders of shares present in person or represented by proxy at the meeting and entitled to vote on the proposal	No effect	No effect
Ratification of PricewaterhouseCoopers LLP as our independent registered public accounting firm for fiscal year 2023	“For” votes from the holders of a majority of shares present in person or represented by proxy at the meeting and entitled to vote on the proposal	Against	Not applicable

Could other matters be decided at the Annual Meeting?

At the date of this proxy statement, we did not know of any matters to be raised at the Annual Meeting other than those referred to in this proxy statement. If other matters are properly presented at the Annual Meeting for consideration, the proxy holders named on the proxy card will have the discretion to vote on those matters for you.

Who will pay for the cost of this proxy solicitation?

We will pay the cost of soliciting proxies. Our directors, senior executives or employees, acting without special compensation, may also solicit proxies. Proxies may be solicited by personal interview, mail, electronic transmission, facsimile transmission or telephone. We are required to send copies of proxy-related materials or additional solicitation materials to brokers, fiduciaries and custodians who will forward these materials to the beneficial owners of our shares. On request, we will reimburse brokers and other persons representing beneficial owners of shares for their reasonable expenses in forwarding these materials to beneficial owners.

Who will count the vote?

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

How can I find out the results of the voting at the Annual Meeting?

We will announce preliminary voting results at our Annual Meeting. We will publish final voting results 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 within four business days after the Annual Meeting, we will disclose the preliminary results in the Current Report on Form 8-K and, within four business days after the final voting results are known to us, file an amended Current Report on Form 8-K to disclose the final voting results.

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

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 31, 2023 to our Corporate Secretary at 1800 El Camino Real, Suite D, Menlo Park, CA 94027. However, if our 2024 Annual Meeting of Stockholders is held more than 30 days before or more than 30 days after the one-year anniversary of the Annual Meeting, then the deadline will be a reasonable time prior to the time that we begin to print and mail our proxy materials.

If you wish to submit a proposal (including a director nomination) at our 2024 Annual Meeting of Stockholders that is not to be included in next year’s proxy materials, you must do so by not earlier than 5:00 p.m. Pacific Time on February 8, 2024 and not later than 5:00 p.m. Pacific Time on March 9, 2024, provided, however, that if our 2024 Annual Meeting of Stockholders is held more than 30 days before or more than 30 days after the one-year anniversary of the Annual Meeting, your proposal must be submitted not earlier than (i) the close of business on the 120th day prior to our 2024 Annual Meeting

of Stockholders and not later than the close of business on the later of the 90th day prior to our 2024 Annual Meeting of Stockholders or (ii) the 10th day following the day on which public announcement of such meeting is first made. You are advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations.

The proxy solicited by our Board of Directors for the 2024 Annual Meeting of Stockholders will confer discretionary voting authority with respect to (i) any proposal presented by a stockholder at that meeting for which we have not been provided with timely notice and (ii) any proposal made in accordance with our bylaws, even if the 2024 proxy statement briefly describes the matter and how management proxy holders intend to vote on it, if the stockholder does not comply with the requirements of Rule 14a-4(c)(2) promulgated under the Securities Exchange Act of 1934, as amended (“Exchange Act”).

Nomination of Director Candidates

You may propose director candidates for consideration by our nominating and corporate governance committee. Any such recommendations should include the nominee’s name and qualifications for membership on our Board of directors and should be directed to our Secretary at the address set forth above. In addition, our amended and restated bylaws permit stockholders to nominate directors for election at an annual meeting of stockholders. To nominate a director, the stockholder must provide the information required by our amended and restated bylaws and send timely notice to our Secretary in accordance with our amended and restated bylaws, which, in general, require that the notice be received by our Corporate Secretary within the time periods described above under “Stockholder Proposals” for stockholder proposals that are not intended to be included in a Proxy Statement. In addition to satisfying the foregoing requirements under our amended and restated bylaws, to comply with the universal proxy rules in connection with our 2024 Annual Meeting of Stockholders, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice to the Company that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 8, 2024, or if the date of our 2024 Annual Meeting of Stockholders has changed by more than 30 days from the date of our 2023 Annual Meeting, then the notice must be provided by the later of (i) 60 days prior to the date of our 2024 Annual Meeting of Stockholders or (ii) the 10th day following the day on which public announcement of the date of our 2024 Annual Meeting of Stockholders is first made.

How may I obtain AN2 Therapeutic’s Form 10-K and other financial information?

DIRECTORS AND CORPORATE GOVERNANCE

Board Composition

Our business affairs are managed under the direction of our Board of directors, which is currently composed of nine members. Our directors are divided into three classes serving staggered three year terms. Upon expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three year term at the annual meeting of stockholders in the year in which their term expires. As a result of this classification of directors, it generally takes at least two annual meetings of stockholders for stockholders to effect a change in a majority of the members of our Board of directors.

The names, ages, principal occupations and certain other information about the director nominees with terms expiring at the Annual Meeting and the additional members of our Board (including the skills and qualifications that led to the conclusion that they should serve as directors) are set forth below.

We believe that Dr. Readnour’s more than 30 years of experience moving products from discovery through commercialization makes him an appropriate member of our Board of directors.

Director Independence

Our common stock is listed on The Nasdaq Stock Market (“Nasdaq”). Under the rules of Nasdaq, independent directors must comprise a majority of a listed company’s board of directors. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Under the rules of Nasdaq, a director will only qualify as an “independent director” if, in the opinion of that company’s board

of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

To be considered to be independent for purposes of Rule 10A-3 and under the rules of Nasdaq, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries.

To be considered independent for purposes of Rule 10C-1 and under the rules of Nasdaq, the Board of directors must affirmatively determine that each member of the compensation committee is independent, including a consideration of all factors specifically relevant to determining whether the director has a relationship to the company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (i) the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by the company to such director and (ii) whether such director is affiliated with the company, a subsidiary of the company or an affiliate of a subsidiary of the company.

Our Board undertook a review of its composition, the composition of its committees and the independence of our directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that none of our directors, other than Mr. Easom, have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the rules of Nasdaq. Our Board of directors has determined that Mr. Easom, by virtue of his position as our Chief Executive Officer, is not independent under applicable rules and regulations of the SEC and the Nasdaq Listing Rules.

In making these determinations, our Board considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them. There are no family relationships among any of our directors or executive officers.

Board Leadership Structure

Our Board is currently chaired by Mr. Zakrzewski. As a general policy, our Board believes that separation of the positions of chairperson of our Board and Chief Executive Officer can reinforce the independence of our Board from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of our Board as a whole. As such, Mr. Easom serves as our Chief Executive Officer while Mr. Zakrzewski serves as the chairperson of our Board. While the positions of chief executive officer and chair are currently held by different individuals, we do not believe there should be a fixed rule regarding the separation of these positions, or whether the chair should be

an employee of ours or should be elected from among the non-employee directors. Our needs and the individuals available to assume these roles may require different outcomes at different times, and we and our Board believe that retaining that flexibility in these decisions is in our best interests. Our Nominating and Corporate Governance Committee periodically reviews this matter and makes recommendations to the Board.

Board Committees and Meetings

Our Board has established an audit committee, a compensation committee and a nominating and corporate governance committee. The composition and responsibilities of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each of the audit, compensation, and nominating and corporate governance committees is a standing committee and operates pursuant to a separate written charter adopted by our Board that is available on the Investor Relations section of the Company’s website at investor.an2therapeutics.com. The inclusion of our website address in this proxy statement does not include or incorporate by reference into this proxy statement the information on or accessible through our website.

The Board met five times during fiscal year 2022. During fiscal year 2022, each of our directors attended 75% or more of the aggregate of (a) the total number of meetings of the Board held while a director (during the period in which the director served on the Board) and (b) the total number of meetings held by all committees on which the director served (during the period in which the director served on such committees). Pursuant to our Corporate Governance Guidelines, each director is encouraged to attend each annual meeting of stockholders.

Audit Committee

The audit committee consists of Ms. Wong, Mr. Aziz and Mr. Zakrzewski. Ms. Wong is the chairperson of the Audit Committee and is the audit committee financial expert, as that term is defined under the SEC rules implementing Section 407 of the Sarbanes-Oxley Act of 2002, and possesses financial sophistication, as defined under the rules of Nasdaq.

Although Mr. Aziz does not fall under the safe harbor provision of Rule 10A-3(e)(1)(ii) of the Exchange Act because Mr. Aziz is a limited partner of a stockholder that owns more than 10% of the Company’s voting power, our Board has determined that each of Mr. Aziz, Mr. Zakrzewski, and Ms. Wong is independent.

Each member of our audit committee can read and understand fundamental financial statements in accordance with applicable requirements. In arriving at these determinations, the Board of directors has examined each audit committee member’s scope of experience and the nature of their employment in the corporate finance sector.

The primary purpose of the audit committee is to discharge the responsibilities of our Board of directors with respect to our corporate accounting and financial reporting processes, systems of internal control and financial-statement audits, and to oversee our independent registered accounting firm. Specific responsibilities of our audit committee include:

•

helping our Board of directors oversee our corporate accounting and financial reporting processes;

•

managing the selection, engagement, qualifications, independence, and performance of a qualified firm to serve as the independent registered public accounting firm to audit our financial statements;

•

discussing the scope and results of the audit with the independent registered public accounting firm, and reviewing, with management and the independent accountants, our interim and year-end operating results;

•

developing procedures for employees to submit concerns anonymously about questionable accounting or audit matters;

•

reviewing related person transactions;

•

obtaining and reviewing a report by the independent registered public accounting firm at least annually, that describes our internal quality control procedures, any material issues with such procedures, and any steps taken to deal with such issues when required by applicable law; and

•

approving, or, as permitted, pre-approving, audit and permissible non-audit services to be performed by the independent registered public accounting firm.

The audit committee operates under a written charter that satisfies the applicable rules of the SEC and Nasdaq listing rules. A copy of the audit committee charter is available to stockholders on the investor relations portion of our website at https://investor.an2therapeutics.com/. The audit committee met five times in fiscal year 2022.

Compensation Committee

The compensation committee consists of Ms. Martin, Dr. Marks, and Dr. Spigelman, each of whom meets the requirements for independence under current Nasdaq listing standards and SEC rules and regulations. Ms. Martin is the chairperson of the compensation committee. Each member of the compensation committee is also a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act. The compensation committee oversees our compensation policies, plans and benefits programs.

The primary purpose of our compensation committee is to discharge the responsibilities of our Board of directors in overseeing our compensation policies, plans and programs, and to review and determine the compensation to be paid to our executive officers, directors and other senior management, as appropriate. Specific responsibilities of our compensation committee include:

•

reviewing and approving the compensation of our chief executive officer, other executive officers, and senior management;

•

reviewing and recommending to our Board of directors the compensation paid to our directors;

•

reviewing and approving the compensation arrangements with our executive officers and other senior management;

•

administering our equity incentive plans and other benefit programs;

•

reviewing, adopting, amending, and terminating, incentive compensation and equity plans, severance agreements, profit sharing plans, bonus plans, change-of-control protections, and any other compensatory arrangements for our executive officers and other senior management;

•

reviewing, evaluating, and recommending to our Board of directors succession plans for our executive officers; and

•

reviewing and establishing general policies relating to compensation and benefits of our employees, including our overall compensation strategy, including base salary, incentive compensation, and equity-based grants, to assure that it promotes stockholder interests and supports our strategic and tactical objectives, and that it provides for appropriate rewards and incentives for our management and employees.

The compensation committee has the right, in its sole discretion, to retain or obtain the advice of compensation consultants, independent legal counsel and other advisers. The compensation committee engaged Aon Consulting as an outside consultant, to advise on compensation-related matters.

Our compensation committee has the authority to form and delegate authority to one or more subcommittees as it deems appropriate from time to time.

The compensation committee operates under a written charter that satisfies the applicable rules of the SEC and Nasdaq listing rules. A copy of the compensation committee charter is available to stockholders on the investor relations portion of our website at https://investor.an2therapeutics.com/. The compensation committee met six times in fiscal year 2022.

Process and Procedure for Compensation Decisions

Our compensation committee is primarily responsible for establishing and reviewing our general compensation strategy. Typically, our compensation committee meets on a regular schedule several times per year. In addition, the compensation committee oversees our compensation and benefit plans and policies, administers our equity incentive plans and reviews and approves annually all compensation decisions relating to all of our executive officers, including our Chief Executive Officer. Generally, our compensation committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. The compensation committee considers recommendations from our Chief Executive Officer regarding the compensation of our executive officers other than himself. For all executives and directors as part of its deliberations, our compensation committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, executive and director stock ownership information, company stock performance data, analyses of historical executive or director compensation levels and current company-wide compensation levels and recommendations of our compensation committee’s compensation consultant, including analyses of executive and director compensation paid at other companies identified by the consultant. Various members of management and other employees as well as outside advisors or consultants are often 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 does not participate in, and is not present during, any deliberations or determinations of the compensation committee regarding his compensation or individual performance objectives.

The charter of the compensation committee grants our compensation committee full access to all of our books, records, facilities, and personnel. In addition, under its charter, our compensation committee has the right to retain or obtain the advice of compensation consultants, independent legal counsel and other advisers and other external resources that our compensation committee considers necessary or appropriate in the performance of its duties, only after taking into consideration the six factors prescribed by the SEC and Nasdaq that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent. In fiscal years 2022 and 2021, the compensation committee retained Aon Consulting, a compensation consultant, to help us determine the appropriate level of overall compensation for our executive officers, as well as assess each separate element of compensation and to assess how our compensation practices compared to the compensation practices of other companies, with a goal of ensuring that the compensation we offer to our executive officers is competitive and fair. As part of its engagement, Aon was requested by our Compensation Committee to develop a comparative peer group of companies and to perform analyses of competitive performance and compensation levels for that peer group. Aon then conducted a review and analysis of our executive and director compensation compared with current market practices and the peer group of companies, to be used for setting 2023 and 2022 executive and director compensation levels. Aon’s review, which consisted of an analysis of our compensation practices against prevailing market practices of identified peer group companies and broader industry trends, analyzed total direct compensation (inclusive of salary, cash bonuses and equity awards) of our executive officers and was based on an assessment of market trends through analysis of available public information in addition to proprietary data provided by Aon. Following an active dialogue with Aon and management and resulting modifications, the compensation committee approved the recommendations, with adjustment as deemed appropriate by the compensation committee.

Compensation Committee Interlocks and Insider Participation

Our compensation committee consisted of Ms. Martin, Dr. Marks, and Dr. Spigelman for the year ended December 31, 2022. None of the members of the compensation committee is currently, or has been at any time, one of our officers or employees. During 2022, no member of our compensation committee or any of our executive officers has or had a relationship that would constitute an interlocking relationship, as defined under applicable SEC rules, with executive officers or directors of another entity.

Please refer to the section of this proxy statement entitled “Certain Relationships and Related Transactions” for information concerning certain transactions involving members of the compensation committee.

Nominating and Corporate Governance Committee

The nominating and corporate governance committee consists of Dr. Readnour, Ms. FitzPatrick, Ms. Wong and Mr. Zakrzewski, each of whom meets the requirements for independence under current Nasdaq listing standards and SEC rules and regulations. Dr. Readnour is the chairperson of the nominating and corporate governance committee. The nominating and corporate governance committee oversees and assists our Board in reviewing and recommending nominees for election as directors. Specifically, the responsibilities of the nominating and corporate governance committee include:

•

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

•

considering and making recommendations to our Board of directors regarding the composition and chairmanship of the committees of our Board of directors;

•

instituting plans or programs for the continuing education of our Board of directors and orientation of new directors;

•

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

Our nominating and corporate governance committee operates under a written charter that satisfies applicable rules of the SEC and Nasdaq listing rules. A copy of the nominating and corporate governance committee charter is available to

stockholders on the investor relations portion of our website at https://investor.an2therapeutics.com/. The nominating and corporate governance committee met two times in fiscal year 2022.

Identifying and Evaluating Director Nominees

Our Board has delegated to the nominating and corporate governance committee the responsibility of identifying individuals qualified to become Board members and recommending to the Board nominees to fill vacancies and newly created directorships and the nominees to stand for election as directors. If the nominating and corporate governance committee determines that an additional or replacement director is required, it may take such measures that it considers appropriate in connection with its evaluation of a director candidate, including candidate interviews, inquiry of the person or persons making the recommendation or nomination, engagement of an outside search firm to gather additional information, or reliance on the knowledge of the members of the committee, the Board or management. In its evaluation of director candidates, including the members of the Board eligible for reelection, the nominating and corporate governance committee will consider the current size and composition of the Board and the needs of the Board and its committees. Some of the factors that our nominating and corporate governance committee considers include, without limitation, character, integrity, judgment, diversity, including diversity in terms of gender, race, ethnicity and experience, independence, area of expertise, corporate experience, length of service, potential conflicts of interest, other commitments and similar factors.

Nominees must also have the highest personal and professional ethics and integrity, proven achievement and competence in the nominee’s field and the ability to exercise sound business judgment, skills that are complementary to those of the existing Board, the ability to assist and support management and make significant contributions to the Company’s success, and an understanding of the fiduciary responsibilities that are required of a member of the Board and the commitment of time and energy necessary to diligently carry out those responsibilities.

A stockholder that wants to recommend a candidate for election to the Board should direct the recommendation in writing by letter to the Company, attention of the Corporate Secretary, at 1800 El Camino Real, Suite D, Menlo Park, California 94027. The recommendation must include the candidate’s name, home and business contact information, detailed biographical data, relevant qualifications, a signed letter from the candidate confirming willingness to serve, information regarding any relationships between the candidate and the Company and evidence of the recommending stockholder’s ownership of Company stock. Such recommendations must also include a statement from the recommending stockholder in support of the candidate, particularly within the context of the criteria for Board membership. In addition, a stockholder must meet the deadlines and other requirements set forth in the Company’s bylaws. The nominating and corporate governance committee will consider candidates recommended by stockholders in the same manner as candidates recommended to the committee from other sources.

Role of the Board in Risk Oversight

Our Board has an active role, as a whole and also at the committee level, in overseeing the management of our risks. Our Board is responsible for general oversight of risks and regular review of information regarding our risks, including credit risks, liquidity risks and operational risks. The compensation committee is responsible for overseeing the management of risks relating to our executive compensation plans and arrangements. The audit committee is responsible for overseeing the management of risks relating to accounting matters and financial reporting. Although each committee is responsible for evaluating certain risks and overseeing the management of such risks, our entire Board is regularly informed through discussions from committee members about such risks. Our Board believes its administration of its risk oversight function has not negatively affected the Board’s leadership structure. The Board’s allocation of risk oversight responsibility may change from time to time based on the evolving needs of the Company.

Compensation Risk Assessment

The compensation committee periodically reviews the Company’s general compensation strategy and reviews the risks arising from the Company’s compensation policies and practices for all employees that are reasonably likely to have a material adverse effect on the Company.

Communications with Directors

Stockholders and other interested parties may communicate with the Board by writing in care of the Corporate Secretary, AN2 Therapeutics, Inc., 1800 El Camino Real, Suite D, Menlo Park, California 94027. Communications intended for a specific director or directors, including the chairperson or the independent directors as a group, should be addressed to the attention of the relevant individual(s) in care of the Corporate Secretary at the same address. Our Corporate Secretary will review all correspondence intended for the Board and will regularly forward to the Board a summary of such correspondence

and copies of correspondence that, in the opinion of the Corporate Secretary, is of significant importance to the functions of the Board or otherwise requires the Board’s attention.

Corporate Governance Guidelines and Code of Business Conduct and Ethics

Our Board has adopted Corporate Governance Guidelines. These guidelines address items such as the qualifications and responsibilities of our directors and director candidates and corporate governance policies and standards applicable to us in general. In addition, our Board has adopted a Code of Business Conduct and Ethics that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer, and other executive and senior

financial officers. The full text of our Corporate Governance Guidelines and our Code of Business Conduct and Ethics is posted on our website at https://investor.an2therapeutics.com/ in the Governance section of our Investors webpage.

Narrative to Summary Compensation Table

Our compensation committee reviews compensation annually for all executive employees, including our named executive officers. In making compensation determinations, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives,

our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders and a long-term commitment to our Company. For setting our 2022 executive compensation levels, our compensation committee also engaged Aon as compensation consultants to develop a comparative peer group of companies and to perform analyses of our executive compensation practices compared with current market practices and the peer group of companies.

Our compensation committee has historically determined our executive officers’ compensation and has typically reviewed and discussed management’s proposed compensation with our Chief Executive Officer for all executives other than our Chief Executive Officer. Based on those discussions and its discretion, our compensation committee then approved the compensation of each executive officer.

Annual Base Salaries

Base salaries for our executive officers are initially established through arm’s-length negotiations at the time of the executive officer’s hiring, taking into account such executive officer’s qualifications, experience, the scope of his or her responsibilities and competitive market compensation paid by other companies for similar positions within the industry and geography. Base salaries are reviewed periodically, typically in connection with our annual review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. In making decisions regarding salary increases, especially in connection with our March 2022 initial public offering, we reviewed the analysis conducted by Aon comparing our compensation practices to current market practices and those of our peer group of companies. The 2022 and 2021 base salaries for our named executive officers are reflected in the table above, as adjusted throughout the year, except no base salary is reported for Mr. Eizen for 2021 given he joined us in 2022.

Non-Equity Incentive Plan Compensation

Each of our named executive officers was eligible to receive an annual incentive bonus based on the attainment of corporate objectives for the fiscal year ended December 31, 2022, approved by our Board in February 2023. The target bonus for each of Mr. Easom, Dr. Eckburg and Mr. Eizen was 50%, 40% and 40% of his base salary, respectively. The compensation committee of our Board has the authority, in its sole discretion and at any time, to increase, reduce or eliminate a participant’s actual award, and/or increase, reduce or eliminate the amount allocated to the bonus pool for a particular performance period. In February 2023, the Board assessed our performance against our 2022 corporate goals and, based on such performance, awarded a cash annual incentive bonus to each of Mr. Easom, Dr. Eckburg and Mr. Eizen equal to 90% of his target bonus amount for 2022.

For 2021, each of our named executive officers (other than Mr. Eizen who joined us in 2022) was eligible to receive an annual incentive bonus based on the achievement of certain of our 2021 corporate goals. The target bonus for each of Mr. Easom and Dr. Eckburg was 40% and 30% of his base salary, respectively. In February 2022, our Board assessed Company performance against our 2021 corporate goals and based on such performance, awarded a cash annual incentive bonus to each of our named executive officers (other than Mr. Eizen) equal to 100% of his target bonus amount for 2021. These bonuses were paid in early 2022.

Equity-Based Incentive Awards

Our equity-based incentive awards are designed to align our interests and those of our stockholders with those of our employees and consultants, including our executive officers. Our Board or an authorized committee thereof is responsible for approving equity grants. Historically, we have generally used stock options as an incentive for long-term compensation to our executive officers because stock options allow our executive officers to profit from this form of equity compensation only if our stock price increases relative to the stock option’s exercise price, which exercise price is set at the fair market value of our common stock on the date of grant.

We may grant equity awards at such times as our Board or compensation committee determines appropriate. Our executives generally are awarded an initial grant in the form of a stock option in connection with their commencement of employment with us. Additional grants may occur periodically in order to specifically incentivize executives with respect to achieving certain corporate goals or to reward executives for exceptional performance.

Prior to our March 2022 initial public offering, we granted all stock options pursuant to our Amended and Restated 2017 Equity Incentive Plan (the “2017 Plan”). All equity incentive awards granted since our initial public offering have been granted pursuant to our 2022 Equity Incentive Plan (the “2022 Plan”).

All stock options are granted with an exercise price per share that is no less than the fair market value of our common stock on the date of grant of such award. Our stock option awards granted to our named executive officers generally vest over a

four-year period and may be subject to acceleration of vesting and exercisability under certain termination and change in control events, as described in more detail under the subsections below titled “Employment Arrangements” and “Potential Payments and Benefits upon Termination or Change in Control.”

In May 2022, our Board granted to Mr. Easom and Dr. Eckburg an option to purchase 225,000 and 66,000 shares of our common stock, respectively, at an exercise price of $17.28 per share. The shares shall vest in 48 monthly increments commencing on the one-month anniversary of the vesting commencement date of March 25, 2022, subject to continued service to the Company through each such vesting date. In October 2022, our Board granted to Mr. Eizen an option to purchase 92,000 shares of our common stock at an exercise price of $17.88 per share. 25% of the shares shall vest on the one-year anniversary of the vesting commencement date of September 29, 2022, and the remainder vest on a monthly basis thereafter, subject to continued service to the Company through each such vesting date. The option grants are set forth in the Outstanding Equity Awards at December 31, 2022 table below.

In April 2021, our Board granted to Mr. Easom and Dr. Eckburg an option to purchase 249,999 and 118,999 shares of our common stock, respectively, at an exercise price of $6.60 per share. Mr. Easom’s shares shall vest in 48 monthly increments commencing on the one-month anniversary of the vesting commencement date, subject to continued service to the Company through each such vesting date. Mr. Eckburg’s shares shall vest 25% on the one-year anniversary of the vesting commencement date, and the remainder vest on a monthly basis thereafter. The option grants are set forth in the Outstanding Equity Awards at December 31, 2022 table below.

Each named executive officer is eligible for severance and change of control-related benefits as described below.

Potential Payments and Benefits upon Termination or Change in Control

Our Board of directors has adopted a Severance and Change in Control Plan (“Severance Plan"), in which our named executive officers, and certain other executives, participate. The benefits provided in the Severance Plan replace any severance for which our named executive officers may be eligible under their existing offer letters or other employment agreements or arrangements, except to the extent such offer letters or other agreements or arrangements provide for greater benefits; provided, that, the defined terms in the Severance Plan supersede the corresponding defined terms or other similar terms in such offer letter or other agreements or arrangements.

The Severance Plan provides that upon a termination by us for any reason other than for “cause,” as defined in the Severance Plan, death or “disability,” as defined in the Severance Plan, outside of the change in control period (i.e., the period starting three months before and ending one year after a “change in control,” as defined in the Severance Plan), an eligible participant will be entitled to receive, subject to the execution and delivery of an effective release of claims in favor of our company and continued compliance with all applicable restrictive covenants, (i) a lump sum amount equal to 100% of the annual base salary in effect immediately prior to the date of termination for our Chief Executive Officer and 75% of the annual base salary in effect immediately prior to the date of termination for our other named executive officers, (ii) an additional cash lump sum equal to any earned but unpaid annual bonus for any performance years that were completed as of the date of termination, and (iii) if the named executive officer timely elects, continued group health plan continuation coverage under the Consolidated Omnibus Budget Reconciliation Act, or COBRA, the premiums on behalf of such officer and any eligible dependents for 12 months following termination for our Chief Executive Officer and nine months following termination for our other named executive officers. The payments under (i) and (ii) will be paid within 30 days after the delivery of an effective release of claims by the named executive officers.

The Severance Plan also provides that upon a (A) termination by us other than for cause, death or disability or (B) resignation for “good reason,” as defined in the Severance Plan, in each case within the change in control period, an eligible participant will be entitled to receive, in lieu of the payments and benefits above and subject to the execution and delivery of an effective release of claims in favor of our company and continued compliance with all applicable restrictive covenants, (i) a lump sum amount equal to 150% of the base salary and 150% of the target annual bonus in effect immediately prior to the date of termination for our Chief Executive Officer and 100% of the base salary and 100% of the target annual bonus in effect immediately prior to the date of termination for our other named executive officers, (ii) an additional cash lump sum equal to any earned but unpaid annual bonus for any performance years that were completed as of the date of termination, (iii) if the named executive officer timely elects continued group health plan continuation coverage, the COBRA premiums on behalf of such officer and any eligible dependents for 18 months following termination for our Chief Executive Officer and 12 months following termination for our other named executive officers, and (iv) for all outstanding and unvested equity awards of our company that are subject to vesting held by the participant, full accelerated vesting of such awards; provided, that the performance conditions applicable to any outstanding and unvested equity awards subject to performance-based vesting will be deemed satisfied at the target level specified in the terms of the applicable award agreement.

The payments and benefits provided under the Severance Plan in connection with a change in control may not be eligible for a federal income tax deduction by us pursuant to Section 280G of the Code. These payments and benefits may also subject an eligible participant, including the named executive officers, to an excise tax under Section 4999 of the Code. If the payments or benefits payable in connection with a change in control would be subject to the excise tax imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to the participant.

401(k) Plan

We maintain a 401(k) retirement savings plan for the benefit of our employees.

As a tax-qualified retirement plan, pre-tax contributions to the 401(k) plan and earnings on those pre-tax contributions are not taxable to the employees until distributed from the 401(k) plan, and earnings on Roth contributions are not taxable when distributed from the 401(k) plan.

In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We will remain an emerging growth company until the earliest of (i) December 31, 2027, (ii) the last day of the first fiscal year in which our annual gross revenue is $1.235 billion or more, (iii) the date on which we have, during the previous rolling three-year period, issued more than $1.235 billion

in non-convertible debt securities, or (iv) the date on which we are deemed to be a “large accelerated filer” as defined in the Exchange Act.

Under the Director Compensation policy, each non-employee director is eligible to receive compensation for his or her service consisting of the following annual cash retainers and equity awards. Our Board has the discretion to revise non-employee director compensation as it deems necessary or appropriate.

Initial Award. Upon joining the Board, each newly-elected non-employee director will be granted a one-time grant (the “Director Initial Grant”) of a non-statutory stock option with a grant-date value of $209,093 on the date of such director’s election or appointment to the Board of directors. The Director Initial Grant will vest in substantially equal monthly installments over three years, subject to continued service as a Service Provider through each vesting date.

•

Annual Award. Each non-employee director (including the chairman of the Board) will be granted an annual award (the “Director Annual Grant”) of a non-statutory stock award with a grant-date value of $104,546; provided however, that any director who receives a Director Initial Grant at least three months, but less than six months, prior to the annual meeting stockholders of our company will be granted an award of a non-statutory stock option with a grant-date value of $52,273. The Director Annual Grant will vest in full on the earlier of the one-year anniversary of the grant date or on the date of our next annual meeting of stockholders, subject to continued service as a Service Provider through each vesting date. The Director Initial Grant and Director Annual Grant are subject to full acceleration vesting upon the sale of our company.

Pursuant to the Director Compensation Policy, no non-employee director may be issued, in any fiscal year, cash compensation and equity awards with an aggregate value greater than $750,000. Any cash compensation paid or equity awards granted to an individual for his or her services as an employee, for his or her services as a consultant (other than as a non-employee director), will not count for purposes of this limitation.

Limitation of Liability and Indemnification

Our amended and restated certificate of incorporation and amended and restated bylaws provide that we will indemnify our directors and officers, and may indemnify our employees and other agents, to the fullest extent permitted by Delaware law. Delaware law prohibits our amended and restated certificate of incorporation from limiting the liability of our directors for the following:

•

any breach of the director’s duty of loyalty to us or to our stockholders;

•

acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

•

unlawful payment of dividends or unlawful stock repurchases or redemptions; and

•

any transaction from which the director derived an improper personal benefit.

Such limitation of liability does not apply to liabilities arising under federal securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission.

Our amended and restated certificate of incorporation authorize us to indemnify our directors, officers, employees and other agents to the fullest extent permitted by Delaware law. Our amended and restated bylaws provide that we are required to indemnify our directors and officers to the fullest extent permitted by Delaware law and may indemnify our other employees and agents. Our amended and restated bylaws also provide that, on satisfaction of certain conditions, we will advance

expenses incurred by a director or officer in advance of the final disposition of any action or proceeding, and permit us to secure insurance on behalf of any officer, director, employee, or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the provisions of Delaware law. We have entered and expect to continue to enter into agreements to indemnify our directors, executive officers and other employees as determined by the Board of directors. With certain exceptions, these agreements provide for indemnification for related expenses including attorneys’ fees, judgments, fines, and settlement amounts incurred by any of these individuals in any action or proceeding.

We believe that these amended and restated certificate of incorporation and amended and restated bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also maintain customary directors’ and officers’ liability insurance.

The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted for directors, executive officers, or persons controlling us, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

BENEFICIAL OWNERSHIP OF SHARES OF COMMON STOCK

The following table sets forth certain information with respect to the beneficial ownership of our common stock as of March 15, 2023 for:

•

each beneficial owner of 5% or more of the outstanding shares of our common stock;

•

each of our directors;

•

each of our named executive officers; and

•

all directors and executive officers as a group.

The number of shares of common stock beneficially owned by each person or entity is determined in accordance with the applicable rules of the SEC and includes voting or investment power with respect to shares of our common stock. The information is not necessarily indicative of beneficial ownership for any other purpose. Unless otherwise indicated, to our knowledge, all persons named in the table have sole voting and investment power with respect to their shares of common stock, except to the extent authority is shared by spouses under community property laws. The inclusion herein of any shares as beneficially owned does not constitute an admission of beneficial ownership.

Applicable percentage ownership is based on 19,402,658 shares of common stock outstanding at March 15, 2023. In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares subject to options held by the person that are currently exercisable within 60 days of March 15, 2023. However, we did not deem such shares outstanding for the purpose of computing the percentage ownership of any other person.

License Agreements

Anacor Pharmaceuticals

In November 2019, we entered into an exclusive worldwide license agreement with Anacor for certain compounds and other intellectual property controlled by Anacor for the treatment, diagnosis, or prevention of disease. In exchange for the worldwide, sublicensable, exclusive right and licenses to develop, manufacture, and commercialize the specified compounds, we paid Anacor a $2.0 million upfront payment in November 2019 and issued Anacor shares of Series A Preferred Stock in November 2019, and additional shares in October 2020 in conjunction with the first and second closings of our Series A redeemable convertible preferred stock financing, respectively. We agreed to make further payments to Anacor upon achievement of various development milestones for an aggregate maximum payment of $2.0 million, various commercial and sales threshold milestones for an aggregate maximum payment of $125.0 million, and up to 50% of royalties received under certain sublicensing arrangements. Royalties are subject to certain customary reductions, including lack of patent coverage and generic product entry. We also agreed to pay Anacor sales royalties as a percentage of net sales ranging from single to mid-teens.

Brii Biosciences

Adjuvant purchased shares of the Company’s Series A redeemable convertible preferred stock in 2019 and 2020 for a total investment of $5.0 million.

In conjunction with Adjuvant’s investment in the Company’s Series B redeemable convertible preferred stock financing in March 2021, the Company entered into an Amended and Restated Global Health Agreement (the “Adjuvant Amendment”).

Adjuvant purchased shares of the Company’s Series B redeemable convertible preferred stock in 2021 for a total investment of $7.0 million.

If we do not maintain compliance with the investment commitments under the Adjuvant Agreement and the Adjuvant Amendment (together, the “Adjuvant Agreements”), Adjuvant may be entitled to repayment for any portion of its investment that is not used for the purposes outlined in the Adjuvant Agreements. Risk of repayment under the Global Health Agreement is limited to Adjuvant’s aggregate investment of $12.0 million in our Series A and Series B redeemable convertible preferred stock in 2019, 2020 and March 2021. Adjuvant’s aggregate investment of $12.0 million has been fully utilized toward development of epetraborole, including toxicology studies, clinical trials, and manufacturing activities to the extent development of epetraborole for NTM lung disease overlaps with development of epetraborole for melioidosis, tuberculosis, and any other mutually agreed-upon products.

The indemnification agreements and our amended restated certificate of incorporation and amended and restated bylaws require us to indemnify our directors, executive officers and certain controlling persons to the fullest extent permitted by Delaware law.

Related Person Transaction Policy

Our audit committee maintains the primary responsibility for reviewing and approving or disapproving “related person transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. The charter of our audit committee will provide that our audit committee shall review and approve in advance any related person transaction.

Our related person transaction policy provides that we are not permitted to enter into any transaction that exceeds $120,000 and in which any related person has a direct or indirect material interest without the consent of our audit committee. In approving or rejecting any such transaction, our audit committee is to consider the relevant facts and circumstances available and deemed relevant to our audit committee, including whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

PROPOSAL 2 — Ratification of Independent Registered Public Accounting Firm

We are asking our stockholders to ratify the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm.

In the event that our stockholders fail to ratify the selection, the Audit Committee will review its future selection of independent auditors. Even if this selection is ratified, pursuant to the Sarbanes-Oxley Act of 2002, the audit committee is directly responsible for the appointment, compensation, retention and oversight of the work of our independent registered public accounting firm and may determine to change the firm selected at such time and based on such factors as it determines to be appropriate.

Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting to answer appropriate questions. They also will have the opportunity to make a statement if they desire to do so.

TRANSACTION OF OTHER BUSINESS

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, the persons appointed in the accompanying proxy intend to vote the shares represented thereby in accordance with their best judgment on such matters, under applicable laws.

REQUIREMENTS, INCLUDING DEADLINES, FOR SUBMISSION OF PROXY PROPOSALS, NOMINATION OF DIRECTORS AND OTHER BUSINESS OF STOCKHOLDERS

Under the rules of the SEC, if a stockholder would like us to include a proposal in our proxy statement and form of proxy for presentation at our 2024 Annual Meeting of Stockholders, the proposal must be received by us at our principal executive offices at 1800 El Camino Real, Suite D, Menlo Park, California 94027, to the attention of the Corporate Secretary, no later than December 31, 2023.

Alternatively, under our bylaws, if a stockholder would like to propose a matter for presentation at the 2024 Annual Meeting of Stockholders rather than for inclusion in the proxy materials, or would like to nominate a person as a candidate for election to the Board at the 2024 Annual Meeting of Stockholders, the stockholder must follow certain procedures contained in our bylaws. Stockholders may request a free copy of our bylaws from:

AN2 Therapeutics, Inc.

Attn: Corporate Secretary

1800 El Camino Real, Suite D

Menlo Park, California 94027

Under the bylaws, notice of a nomination or other business must be delivered to the Corporate Secretary no later than the close of business on March 9, 2024 and no earlier than the close of business on February 8, 2024. If the date of our 2024 Annual Meeting of Stockholders is advanced more than 30 days prior to, or delayed by more than 30 days after, the anniversary of the date of the 2023 Annual Meeting of Stockholders, notice must be delivered to the Corporate Secretary not earlier than the close of business on the 120th day prior to the 2024 Annual Meeting of Stockholders nor later than the close of business on the later of (i) the 90th day prior to the 2024 Annual Meeting of Stockholders or (ii) the 10thday following the day on which public announcement of the date of the 2024 Annual Meeting of Stockholders is first made. Nominations and the proposal of other business also must satisfy other requirements set forth in the bylaws. The chairman of the meeting may refuse to acknowledge the introduction of any stockholder proposal or nomination not made in compliance with the foregoing procedures.

If a stockholder fails to comply with the foregoing deadlines established under the bylaws, the Company will have discretionary authority to vote shares under proxies we solicit when and if the nomination or other business is raised at the Annual Meeting of Stockholders and, to the extent permitted by law, on any other business that may properly come before the Annual Meeting and any adjournments or postponements.

HOUSEHOLDING OF ANNUAL MEETING MATERIALS

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy materials with respect to two or more stockholders sharing the same address by delivering a single annual report, proxy statement and Notice of Internet Availability to those stockholders. This process, which is commonly referred to as “householding,” potentially provides convenience for stockholders and cost savings for companies. Although we do not household for registered stockholders, a number of brokerage firms have instituted householding for shares held in street name, delivering a single set of proxy materials to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that the broker will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, now or in the future, you no longer wish to participate in householding and would prefer to receive a separate annual report, proxy statement and Notice of Internet Availability, please notify us by calling (650) 331-9090 or by sending a written request to 1800 El Camino Real, Suite D, Menlo Park, California 94027, Attention: Corporate Secretary, and we will promptly deliver a separate copy of our annual report and proxy statement. If you are receiving multiple copies of the annual report and proxy statement and wish to receive only one, please notify your broker.

DELINQUENT SECTION 16(A) REPORTS

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

SEC regulations require us to identify in this proxy statement anyone who filed a required report late during the most recent fiscal year. Based solely on our review of forms we received and written representations of our executive officers, directors and 10% stockholders, we believe that during our fiscal year ended December 31, 2021, all Section 16(a) filing requirements were satisfied on a timely basis, other than the following exception: a late filing for Mr. Eizen was submitted on October 28, 2022, covering his initial grant upon hire.
