PROXY STATEMENT FOR THE 2023 ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON THURSDAY, MAY 25, 2023

The board of directors of Phathom Pharmaceuticals, Inc. is soliciting the enclosed proxy for use at the annual meeting of stockholders, including at any adjournments or postponements of the meeting, to be held virtually at www.virtualshareholdermeeting.com/PHAT2023, on May 25, 2023 at 11:30 a.m., Eastern Time.

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

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Accordingly, we have elected to comply with the scaled-down executive compensation disclosure requirements applicable to emerging growth companies and we are not required to include a Compensation Discussion and Analysis section in this proxy statement. 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 votes must be conducted.

Important Notice Regarding the Availability of Proxy Materials for

the Annual Meeting of Stockholders to be Held on May 25, 2023:

This proxy statement and our Annual Report on Form 10-K are available electronically at www.proxyvote.com.

GENERAL INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why am I receiving these materials?

We have prepared these proxy materials, including this proxy statement and the related proxy card, because our board of directors is soliciting your proxy to vote at the 2023 annual meeting of stockholders. This proxy statement summarizes information related to your vote at the annual meeting. All stockholders who find it convenient to do so are cordially invited to attend the annual meeting via live webcast. However, you do not need to attend the meeting to vote your shares. Instead, you may simply submit your proxy via the Internet in accordance with the instructions provided on the Notice of Internet Availability of Proxy Materials or if you elected to receive printed copies of the proxy materials, you may submit your proxy via telephone or by completing, signing and returning the enclosed proxy card.

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

In accordance with rules of the Securities and Exchange Commission, or SEC, we use the Internet as the primary means of furnishing proxy materials to our stockholders. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials to our stockholders with instructions on how to access the proxy materials over the Internet or request a printed copy of the materials, and for voting over the Internet.

Stockholders may follow the instructions in the Notice of Internet Availability of Proxy Materials to elect to receive future proxy materials in print by mail or electronically by email. We encourage our stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of its annual meetings and reduce the cost to us associated with the printing and mailing of materials.

We intend to mail the Notice of Internet Availability of Proxy Materials on or before April 13, 2023, to all stockholders of record entitled to vote at the annual meeting. You will need the 16‐digit control number provided on the Notice of Internet Availability of Proxy Materials or your proxy card (if applicable).

Why are you holding a virtual meeting instead of a physical meeting?

We are excited to embrace technology and provide expanded access, improved communication and cost savings for our company and our stockholders. We believe that hosting a virtual meeting will enable more of our stockholders to attend and participate in the meeting because our stockholders can participate from any location around the world with Internet access.

What if I have trouble accessing the Annual Meeting virtually?

The virtual meeting platform is fully supported across browsers (Microsoft Edge, Firefox, Chrome and Safari) and devices (desktops, laptops, tablets and cell phones) running the most up-to-date version of applicable software and plugins. Participants should ensure that they have a strong WiFi connection wherever they intend to participate in the meeting. We encourage you to access the meeting prior to the start time. A link on the meeting page will provide further assistance should you need it.

Only stockholders of record at the close of business on the record date for the 2023 annual meeting, March 30, 2023, are entitled to vote at the annual meeting. At the close of business on this record date, there were 43,602,984 shares of our common stock outstanding. Common stock is our only class of stock entitled to vote.

Stockholders of Record: Shares Registered in Your Name

If, on the record date, your shares were registered directly in your name with the transfer agent for our common stock, Computershare Trust Company, N.A., then you are a stockholder of record. As a stockholder of record, you may vote your shares by proxy via the Internet by visiting www.proxyvote.com, by telephone or by mail. You will need the 16-digit control number included on your Notice of Internet Availability of Proxy Materials or your proxy card (if applicable). Whether or not you plan to participate in the virtual annual meeting, we encourage you to vote by proxy via the Internet, by telephone or by mail, as instructed below to ensure your vote is counted.

Beneficial Owners: Shares Registered in the Name of a Broker or Bank

If, on the record date, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the virtual annual meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the annual meeting, but you will need the 16‐digit control number provided on the voting instructions that accompanied your proxy materials from your broker, bank or other agent.

What am I voting on?

There are three proposals scheduled for a vote:

Proposal 1: To elect two directors to serve as Class I directors for a three-year term.

Proposal 2: To consider and vote upon the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2023.

Proposal 3: To approve an amendment to the Company’s Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”) to limit the liability of certain officers of the Company.

How many votes do I have?

Each share of our common stock that you own as of March 30, 2023, entitles you to one vote.

How do I vote?

With respect to the election of directors, you may either vote “For” all of the nominees to the board of directors or you may “Withhold” your vote for any nominee you specify. With respect to each of the remaining items, (i) the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, and (ii) the approval of the amendment to our Amended and Restated Certificate of Incorporation, you may vote “For,” “Against” or “Abstain” from voting.

Stockholders of Record: Shares Registered in Your Name

If you are a stockholder of record, there are several ways for you to vote your shares. Whether or not you plan to attend the meeting, we urge you to vote by proxy prior to the virtual annual meeting to ensure that your vote is counted.

•

Via the Internet: You may vote at www.proxyvote.com, 24 hours a day, seven days a week, by following the instructions provided in the Notice of Internet Availability of Proxy Materials. Votes submitted via the Internet must be received by 11:59 p.m., Eastern Time, on May 24, 2023.

•

By Telephone: If you request printed copies of the proxy materials by mail, you may vote using a touch-tone telephone by calling (800) 690-6903, 24 hours a day, seven days a week. Have your proxy card available when you call and use the 16‐digit control number shown on your Notice of Internet Availability or your proxy card (if applicable). Votes submitted by telephone must be received by 11:59 p.m., Eastern Time, on May 24, 2023.

•

By Mail: If you request printed copies of the proxy materials by mail, you may vote using your proxy card by completing, signing, dating and returning the proxy card in the self-addressed, postage-paid envelope provided. If you properly complete your proxy card and send it to us in time to vote, your proxy (one of the individuals named on your proxy card) will vote your shares as you have directed.

•

At the Virtual Annual Meeting: You may still attend the virtual annual meeting and vote during the meeting even if you have already voted by proxy. To vote during the meeting visit www.virtualshareholdermeeting.com/PHAT2023 on the day of the meeting; you will need the 16‐digit control number provided on the Notice of Internet Availability of Proxy Materials or your proxy card (if applicable).

Beneficial Owners: Shares Registered in the Name of a Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received voting instructions from that organization rather than directly from us. Please check with your bank, broker, or other agent and follow the voting instructions they provide to vote your shares. Generally, you have three options for returning your proxy.

•

By Method Listed on Voting Instruction Card: Please refer to your voting instruction card or other information provided by your bank, broker or other agent to determine whether you may vote by telephone or electronically on the Internet and follow the instructions on the voting instruction card or other information provided by your broker, bank or other agent. A large number of banks and brokerage firms offer Internet and telephone voting. If your bank, broker or other agent does not offer Internet or telephone voting information, please follow the other voting instructions they provide to vote your shares.

•

By Mail: You may vote by signing, dating and returning your voting instruction card in the pre-addressed envelope provided by your broker, bank or other agent.

•

At the Virtual Annual Meeting: To vote at the virtual annual meeting, visit www.virtualshareholdermeeting.com/PHAT2023 on the day of the meeting; you will need the 16‐digit control number provided on the voting instructions that accompanied your proxy materials from your broker, bank or other agent. If you do not have a 16-digit control number, you will be able to join the virtual annual meeting as a “guest,” but will not be able to vote or ask questions at the meeting.

May I revoke my proxy?

If you give us your proxy, you may revoke it at any time before it is exercised. You may revoke your proxy in any one of the three following ways:

•

you may send in another signed proxy with a later date,

•

you may authorize a proxy again on a later date on the Internet (only the latest Internet proxy submitted prior to the annual meeting will be counted), or

•

you may notify our corporate secretary, Larry Miller, at 100 Campus Drive, Suite 102, Florham Park, New Jersey 07932, in writing before the annual meeting that you have revoked your proxy, after which you are entitled to submit a new proxy or vote during the virtual annual meeting.

What constitutes a quorum?

The presence at the annual meeting, in person (virtually) or by proxy, of holders representing a majority of our outstanding common stock as of March 30, 2023, or approximately 21,801,492 shares, constitutes a quorum at the meeting, permitting us to conduct our business.

What vote is required to approve each proposal?

Proposal 1: Election of Directors. The two nominees who receive the most “For” votes (among votes properly cast in person or by proxy) will be elected. Only votes “For” or “Withhold” will affect the outcome.

Proposal 2: Ratification of Independent Registered Public Accounting Firm. The ratification of the appointment of Ernst & Young LLP must receive “For” votes from the holders of a majority in voting power of the votes cast affirmatively or negatively on the proposal. Only votes “For” or “Against” will affect the outcome.

Proposal 3: Approval of Amendment to Amended and Restated Certificate of Incorporation. Approval of Proposal 3 requires the affirmative vote of a majority of the shares outstanding and entitled to vote at the Annual Meeting. With respect to Proposal 3, stockholders may vote “For” or “Against” the proposal or may “Abstain” from voting on the proposal. Shares abstaining from voting on the proposal and broker non-votes will have the same effect as votes “Against” Proposal 3.

Voting results will be tabulated and certified by the inspector of election appointed for the annual meeting.

How will my shares be voted if I do not specify how they should be voted?

If you are a stockholder of record and you indicate when voting on the Internet or by telephone that you wish to vote as recommended by the Board, then your shares will be voted at the annual meeting in accordance with the Board’s recommendation on all matters presented for a vote at the annual meeting. Similarly, if you sign and return a proxy card but do not indicate how you want to vote your shares for a particular proposal or for all of the proposals, then

for any proposal for which you do not so indicate, your shares will be voted in accordance with the Board’s recommendation.

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

What is the effect of withheld votes, abstentions and broker non-votes?

Shares of common stock held by persons attending the virtual annual meeting but not voting, and shares represented by proxies that reflect withheld votes or abstentions as to a particular proposal, will be counted as present for purposes of determining the presence of a quorum. Abstentions are not an affirmative or negative vote on a proposal, so abstaining does not count as a vote cast and has no effect for purposes of determining whether our stockholders have ratified the appointment of Ernst & Young LLP, our independent registered public accounting firm. The election of directors is determined by a plurality of votes cast, so a “Withhold” vote will not be counted in determining the outcome of such proposal.

Shares represented by proxies that reflect a broker non-vote will be counted as present for purposes of determining the presence of a quorum exists. As discussed above, a broker non-vote occurs when an organization holding shares for a beneficial owner has not received instructions from the beneficial owner and does not have discretionary authority to vote the shares for certain non-routine matters. With regard to the election of directors and approval of an amendment to our Amended and Restated Certificate of Incorporation, which are considered non-routine matters, broker non-votes will not be counted as votes cast and will have no effect on the result of the vote. However, ratification of the appointment of Ernst & Young LLP is considered a routine matter on which a broker or other nominee has discretionary authority to vote. Accordingly, no broker non-votes will likely result from this proposal.

How does the Board recommend that I vote?

The Board recommends that you vote:

•

“For” each of the nominees for election as director;

•

“For” the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; and

•

“For” the approval of an amendment to our Amended and Restated Certification of Incorporation to limit the liability of certain officers of the Company.

If you vote via the Internet, by telephone, or sign and return the proxy card by mail but do not make specific choices, your shares, as permitted, will be voted as recommended by our board of directors. If any other matter is presented at the annual meeting, your proxy will vote in accordance with his or her best judgment. As of the date of this proxy statement, we know of no matters that needed to be acted on at the annual meeting, other than those discussed in this proxy statement.

Who is paying the costs of soliciting these proxies?

We will pay all of the costs of soliciting these proxies. Our directors, officers and other employees may solicit proxies in person or by mail, telephone, fax or email. We will not pay our directors, officers and other employees any additional compensation for these services. We will ask banks, brokers and other institutions, nominees and fiduciaries to forward these proxy materials to their principals and to obtain authority to execute proxies. We will then reimburse them for their expenses. Our costs for forwarding proxy materials will not be significant.

How do I obtain an Annual Report on Form 10-K?

If you would like a copy of our Annual Report on Form 10-K for the year ended December 31, 2022 that we filed with the SEC on February 28, 2023, we will send you one without charge. Please write to:

Phathom Pharmaceuticals, Inc.

100 Campus Drive, Suite 102

Florham Park, NJ 07932

Attn: Corporate Secretary

All of our SEC filings are also available free of charge in the “Investors & Media—Financials & Filings—SEC Filings” section of our website at www.phathompharma.com.

How can I find out the results of the voting at the annual meeting?

Preliminary voting results will be announced at the annual meeting. Final voting results will be published in our current report on Form 8-K to be filed with the SEC within four business days after the annual meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

PROPOSAL 1:

ELECTION OF DIRECTORS

Our board of directors is divided into three classes, with one class of our directors standing for election each year, generally for a three-year term. Directors for each class are elected at the annual meeting of stockholders held in the year in which the term for their class expires and hold office until the third annual meeting following election and until such director’s successor is elected and qualified, or until such director’s earlier death, resignation or removal. The composition of our board of directors is as follows: Class I consists of Terrie Curran and Mark Stenhouse; Class II consists of Michael F. Cola, Frank Karbe and Asit Parikh, M.D., Ph.D.; and Class III consists of Heidi Kunz, David Socks and James Topper, M.D., Ph.D.

At this meeting, two nominees for director are to be elected as Class I directors for a three-year term expiring at our 2026 annual meeting of stockholders and until their successors are duly elected and qualified. The nominees, who were recommended for nomination by the nominating and corporate governance committee of our board of directors, are Terrie Curran and Mark Stenhouse. The Class II directors have one year remaining on their terms of office and the Class III directors have two years remaining on their terms of office.

If no contrary indication is made, proxies in the accompanying form are to be voted for Ms. Curran and Mr. Stenhouse, or if either Ms. Curran or Mr. Stenhouse is not a candidate or is unable to serve as a director at the time of the election (which is not currently expected), for any nominee who is designated by our board of directors to fill the vacancy. Each of Ms. Curran and Mr. Stenhouse is currently a member of our board of directors.

All of our directors bring to the board of directors’ significant leadership experience derived from their professional experience and service as executives or board members of other corporations and/or private equity and venture capital firms. The process undertaken by the nominating and corporate governance committee in recommending qualified director candidates is described below under “Director Nomination Process.” Certain individual qualifications and skills of our directors that contribute to the board of directors’ effectiveness as a whole are described in the following paragraphs.

He also completed postdoctoral work in cancer biology at Massachusetts Institute of Technology. Dr. Parikh’s extensive knowledge of our business and prior oversight of the Takeda team bringing vonoprazan to the Japanese market in seven indications contributed to our board of directors’ conclusion that he should serve as a director of our company.

Director Independence

Our board of directors currently consists of eight members. Our board of directors has determined that Mr. Cola, Mr. Karbe, Ms. Kunz, Dr. Parikh. Mr. Stenhouse and Dr. Topper are independent directors in accordance with the listing requirements of the Nasdaq Global Select Market, or Nasdaq. The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his or her family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, our board of directors has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our board of directors reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and relationships as they may relate to us and our management. There are no family relationships among any of our directors or executive officers.

Board Leadership Structure

Our board of directors is currently led by its chairman, Michael Cola. Our board of directors recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as the company continues to grow. We separate the roles of chief executive officer and chairman of the board of directors in recognition of the differences between the two roles. The chief executive officer is responsible for setting the strategic direction for the company and the day-to-day leadership and performance of the company, while the chairman of the board of directors provides guidance to the chief executive officer and presides over meetings of the full board of directors. We believe that this separation of responsibilities provides a balanced approach to managing the board of directors and overseeing the company.

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

Role of Board in Risk Oversight Process

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

The audit committee reviews information regarding liquidity and operations, and oversees our management of financial risks. Periodically, the audit committee reviews our policies with respect to risk assessment, risk management, loss prevention, cybersecurity, and regulatory compliance. Oversight by the audit committee includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the actions management has taken to limit, monitor or control such exposures. The compensation

committee is responsible for assessing whether any of our compensation policies or programs has the potential to encourage excessive risk-taking. The nominating and corporate governance committee manages risks associated with the independence of the board of directors, corporate disclosure practices and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire board of directors is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered by our board of directors as a whole.

Board of Directors Meetings

Including telephonic meetings, our board of directors met fourteen times during fiscal year 2022. In that year, each director attended at least 75% of the total number of meetings held during such director’s term of service by the board of directors and each committee of the board of directors on which such director served.

Board Committees and Independence

Our board of directors has established three standing committees—audit, compensation and nominating and corporate governance – each of which operates under a charter that has been approved by our board of directors.

Audit Committee

The audit committee’s main function is to oversee our accounting and financial reporting processes and the audits of our financial statements. This committee’s responsibilities include, among other things:

•

appointing our independent registered public accounting firm;

•

evaluating the qualifications, independence and performance of our independent registered public accounting firm;

•

approving the audit and non-audit services to be performed by our independent registered public accounting firm;

•

reviewing the design, implementation, adequacy and effectiveness of our internal accounting controls and our critical accounting policies;

•

discussing with management and the independent registered public accounting firm the results of our annual audit and the review of our quarterly unaudited financial statements;

•

reviewing, overseeing and monitoring the integrity of our financial statements and our compliance with legal and regulatory requirements as they relate to financial statements or accounting matters;

•

reviewing on a periodic basis, or as appropriate, any investment policy and recommending to our board of directors any changes to such investment policy;

•

reviewing with management and our auditors any earnings announcements and other public announcements regarding our results of operations;

•

preparing the report from the committee that the SEC requires in our annual proxy statement;

•

receiving periodic updates from management on our policies, processes, procedures and any significant developments related to the identification, mitigation and remediation of cybersecurity risks;

•

reviewing and approving any related party transactions and reviewing and monitoring compliance with our code of conduct and ethics; and

•

reviewing and evaluating, at least annually, the performance of the audit committee and its members including compliance of the audit committee with its charter.

The members of our audit committee are Ms. Kunz, Mr. Cola, Mr. Karbe and Mr. Stenhouse. Ms. Kunz serves as the chairperson of the committee. The audit committee met five times during fiscal year 2022. All members of our audit committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and Nasdaq. Our board of directors has determined that Ms. Kunz is an “audit committee financial expert” as defined by applicable SEC rules and has the requisite financial sophistication as defined under the applicable

Nasdaq rules and regulations. Our board of directors has determined each of Ms. Kunz, Mr. Cola, Mr. Karbe and Mr. Stenhouse is independent under the applicable rules of the SEC and Nasdaq. The audit committee operates under a written charter that satisfies the applicable standards of the SEC and Nasdaq, which the audit committee will review and evaluate periodically.

Both our external auditor and internal financial personnel meet privately with the audit committee and have unrestricted access to this committee.

Compensation Committee

The compensation committee approves policies relating to compensation and benefits of our officers and employees. The compensation committee approves corporate goals and objectives relevant to the compensation of our Chief Executive Officer and other executive officers, evaluates the performance of these officers in light of those goals and objectives and approves the compensation of these officers based on such evaluations. The compensation committee also approves the issuance of equity awards under our equity plan. The compensation committee will review and evaluate, at least annually, the performance of the compensation committee and its members, including compliance by the compensation committee with its charter.

The members of our compensation committee are Mr. Cola, Mr. Karbe, Mr. Stenhouse, and Dr. Parikh. The compensation committee met six times during fiscal year 2022. Mr. Cola serves as the chairperson of the committee. Our board of directors has determined that each member of our compensation committee is independent under the applicable rules and regulations of Nasdaq and is a “non-employee director” as defined in Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act. The compensation committee operates under a written charter, which the compensation committee will review and evaluate periodically.

Nominating and Corporate Governance Committee

The nominating and corporate governance committee is responsible for assisting our board of directors in discharging the board’s responsibilities regarding the identification of qualified candidates to become board members, the selection of nominees for election as directors at our annual meetings of stockholders (or special meetings of stockholders at which directors are to be elected), and the selection of candidates to fill any vacancies on our board of directors and any committees thereof. In addition, the nominating and corporate governance committee is responsible for overseeing our corporate governance policies, reporting and making recommendations to our board of directors concerning governance matters and oversight of the evaluation of our board of directors.

The members of our nominating and corporate governance committee are Mr. Cola, Mr. Karbe, Ms. Kunz, Dr. Parikh, Mr. Stenhouse, and Dr. Topper. Dr. Parikh serves as chairperson of the committee. The nominating and corporate governance committee met three times during fiscal year 2022. Our board has determined that each member of our nominating and corporate governance committee is independent under the applicable rules and regulations of Nasdaq relating to nominating and corporate governance committee independence. The nominating and corporate governance committee operates under a written charter, which the nominating and corporate governance committee will review and evaluate periodically.

Report of the Audit Committee of the Board of Directors

The audit committee oversees the company’s financial reporting process on behalf of our board of directors. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls. In fulfilling its oversight responsibilities, the audit committee reviewed the audited financial statements in the company’s annual report with management, including a discussion of any significant changes in the selection or application of accounting principles, the reasonableness of significant judgments, the clarity of disclosures in the financial statements and the effect of any new accounting initiatives.

The audit committee reviewed with Ernst & Young LLP, which is responsible for expressing an opinion on the conformity of the company’s audited financial statements with generally accepted accounting principles, its judgments as to the quality, not just the acceptability, of the company’s accounting principles and such other matters as are required to be discussed with the audit committee under generally accepted auditing standards and the matters listed in Public Company Accounting Oversight Board Auditing Standard No. 1301, Communications with Audit

Committees. In addition, the audit committee has discussed with Ernst & Young LLP its independence from management and the company, has received from Ernst & Young LLP the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young LLP’s communications with the audit committee concerning independence, and has considered the compatibility of non-audit services with the auditors’ independence.

The audit committee met with Ernst & Young LLP to discuss the overall scope of its services, the results of its audit and reviews, and the overall quality of the company’s financial reporting. Ernst & Young LLP, as the company’s independent registered public accounting firm, also periodically updates the audit committee about new accounting developments and their potential impact on the company’s reporting. The audit committee’s meetings with Ernst & Young LLP were held with and without management present. The audit committee is not employed by the company, nor does it provide any expert assurance or professional certification regarding the company’s financial statements. The audit committee relies, without independent verification, on the accuracy and integrity of the information provided, and representations made, by management and the company’s independent registered public accounting firm.

In reliance on the reviews and discussions referred to above, the audit committee has recommended to the company’s board of directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2022. The audit committee and the company’s board of directors also have recommended, subject to stockholder approval, the ratification of the appointment of Ernst & Young LLP as the company’s independent registered public accounting firm for 2023.

This report of the audit committee is not “soliciting material,” shall not be deemed “filed” with the SEC and shall not be incorporated by reference by any general statement incorporating by reference this proxy statement into any filing under the Securities Act of 1933, as amended, 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 that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under such acts.

The foregoing report has been furnished by the audit committee.


		Respectfully submitted,

		The Audit Committee of the Board of Directors

Compensation Committee Interlocks and Insider Participation

Mr. Cola (chairperson), Mr. Karbe, Dr. Parikh, and Mr. Stenhouse served on our compensation committee during the 2022 fiscal year. None of the members of our compensation committee during the 2022 fiscal year has ever been one of our officers or employees. None of our executive officers currently serves, or has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our board of directors or compensation committee.

Director Nomination Process

Director Qualifications

Our nominating and corporate governance committee is responsible for reviewing with the board of directors, on an annual basis, the appropriate characteristics, skills and experience required for the board of directors as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current members), the nominating and corporate governance committee, in recommending candidates for election, and the board of directors, in approving (and, in the case of vacancies, appointing) such candidates, will take into account many factors, including the following:

•

personal and professional integrity, ethics and values;

•

experience in corporate management, such as serving as an officer or former officer of a publicly-held company;

•

experience as a board member or executive officer of another publicly-held company;

•

strong finance experience;

•

diversity of expertise and experience in substantive matters pertaining to our business relative to other members of our board of directors;

•

diversity of background and perspective, including, but not limited to, with respect to age, gender, race, place of residence and specialized experience;

•

experience relevant to our business industry and with relevant social policy concerns; and

•

relevant academic expertise or other proficiency in an area of our business operations.

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

Other than the foregoing, there are no stated minimum criteria for director nominees, although the nominating and corporate governance committee may also consider such other factors as it may deem to be in the best interests of our company and our stockholders. The nominating and corporate governance committee does, however, believe it appropriate for at least one, and preferably, several, members of our board of directors to meet the criteria for an “audit committee financial expert” as defined by SEC rules, and that a majority of the members of our board of directors meet the definition of “independent director” under Nasdaq qualification standards. The nominating and corporate governance committee also believes it is appropriate for our Chief Executive Officer to serve as a member of our board of directors.

Identification and Evaluation of Nominees for Directors

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

If any member of our board of directors does not wish to continue in service or if our board of directors decides not to re-nominate a member for re-election or if the board of directors decides to expand the size of the board, the nominating and corporate governance committee identifies the desired skills and experience of a new nominee in light of the criteria above. The nominating and corporate governance committee generally polls our board of directors and members of management for their recommendations. The nominating and corporate governance committee may also review the composition and qualification of the boards of directors of our competitors and may seek input from industry experts or analysts. The nominating and corporate governance committee reviews the qualifications, experience and background of the candidates. Final candidates are interviewed by the members of the nominating and corporate governance committee and by certain of our other independent directors and executive management. In making its determinations, the nominating and corporate governance committee evaluates each individual in the context of our board of directors as a whole, with the objective of assembling a group that can best contribute to the success of our company and represent stockholder interests through the exercise of sound business judgment. After review and deliberation of all feedback and data, the nominating and corporate governance committee makes its recommendation to our board of directors. Historically, the nominating and corporate governance committee has not relied on third-party search firms to identify director candidates. The nominating and corporate governance may in the future choose to do so in those situations where particular qualifications are required or where existing contacts are not sufficient to identify an appropriate candidate.

The nominating and corporate governance committee evaluates nominees recommended by stockholders in the same manner as it evaluates other nominees. We have not received director candidate recommendations from our stockholders, and we do not have a formal policy regarding consideration of such recommendations. However, any recommendations received from stockholders will be evaluated in the same manner that potential nominees suggested by members of our board of directors, management or other parties are evaluated.

Under our amended and restated bylaws, a stockholder wishing to suggest a candidate for director should write to our corporate secretary and provide such information about the stockholder and the proposed candidate as is set forth in our amended and restated bylaws and as would be required by SEC rules to be included in a proxy statement. In addition, the stockholder must include the consent of the candidate and describe any arrangements or undertakings between the stockholder and the candidate regarding the nomination. In order to give the nominating and corporate governance committee sufficient time to evaluate a recommended candidate and include the candidate in our proxy statement for the 2024 annual meeting, the recommendation should be received by our corporate secretary at our principal executive offices in accordance with our procedures detailed in the section below entitled “Stockholder Proposals.”

Corporate Governance

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. Our code of business conduct and ethics, as well as our corporate governance guidelines, audit committee charter, compensation committee charter and nominating and corporate governance committee charter, are available free of charge under the Corporate Governance section of our website at www.phathompharma.com.

Director Compensation

Our non-employee director compensation program provides for annual retainer fees and/or long-term equity awards for our non-employee directors. Each non-employee director receives an annual retainer of $50,000 (increased from $40,000 effective May 25, 2022). Non-employee directors serving as the chairs of the audit, compensation and nominating and corporate governance committees receive additional annual retainers of $20,000, $15,000 and $10,000, respectively. Non-employee directors serving as members of the audit, compensation and nominating and corporate governance committees receive additional annual retainers of $10,000, $7,500 and $5,000, respectively. Additionally, the non-executive chairman of the board receive an additional annual retainer of $40,000. The non-employee directors also receive initial grants of options to purchase 20,000 shares of our common stock upon election to the board of directors, one-third of which will vest on the first anniversary of the grant date and the remainder of which will vest in quarterly installments over the following 24 months, and thereafter annual grants of options to purchase 15,000 shares (increased from 12,500 shares effective May 25, 2022) of our common stock, vesting on the first to occur of (1) the first anniversary of the grant date or (2) the next occurring annual meeting of our stockholders, in each case, subject to the non-employee director continuing in service on our board of directors through such vesting date.

Compensation under our non-employee director compensation program is subject to the annual limits on non-employee director compensation set forth in our 2019 Incentive Award Plan, or 2019 Plan. Our board of directors or its authorized committee may modify the non-employee director compensation program from time to time in the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem relevant from time to time, subject to the annual limit on non-employee director compensation set forth in the 2019 Plan. As provided in the 2019 Plan, our board of directors or its authorized committee may make exceptions to this limit for individual non-employee directors in extraordinary circumstances, as the board of directors or its authorized committee may determine in its discretion, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation or in other compensation decisions involving non-employee directors.

We have reimbursed and will continue to reimburse all of our non-employee directors for their travel, lodging and other reasonable expenses incurred in attending meetings of our board of directors and committees of our board of directors.

The following table summarizes cash and stock compensation received by our non‑employee directors during the year ended December 31, 2022. Ms. Curran is not included in the following table as her compensation is included in the Summary Compensation Table in the “Executive Compensation and Other Information” section below. Mr. Socks also served as a strategic advisor to the Company in 2022.

The amounts are valued based on the aggregate grant date fair value of the option award in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or ASC 718. See Note 7 to our financial statements in our Annual Report on Form 10‑K for the year ended December 31, 2022, filed with the SEC on February 28, 2023, for a discussion of the relevant assumptions used in determining the grant date fair value pursuant to ASC 718. These amounts do not reflect whether the recipient has actually realized or will realize a financial benefit from the awards (such as by exercising stock options). Whether, and to what extent, a non‑employee director realizes a financial benefit from the awards will depend on our actual operating performance, stock price fluctuations and the non‑employee director’s continued service on our board.

Votes withheld from any nominee, abstention and broker non-votes will be counted only for purposes of determining a quorum and are not considered votes cast for the foregoing purpose. Broker non-votes will have no effect on this proposal as brokers or other nominees are not entitled to vote on such proposals in the absence of voting instructions from the beneficial owner.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE ELECTION OF TERRIE CURRAN AND MARK STENHOUSE, PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE SO VOTED UNLESS STOCKHOLDERS SPECIFY OTHERWISE.

PROPOSAL 2:

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee has selected Ernst & Young LLP as the company’s independent registered public accounting firm for the year ending December 31, 2023 and has further directed that management submit the selection of independent registered public accounting firm for ratification by the stockholders at the annual meeting. Ernst & Young LLP has audited the company’s financial statements since our inception in 2019. Representatives of Ernst & Young LLP are expected to be present at the annual meeting, will have an opportunity to make a statement if they so desire, and will be available to respond to appropriate questions.

Stockholder ratification of the selection of Ernst & Young LLP as the company’s independent registered public accounting firm is not required by Delaware law, the company’s amended and restated certificate of incorporation, or the company’s amended and restated bylaws. However, the audit committee is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the audit committee will reconsider whether to retain that firm. Even if the selection is ratified, the audit committee in its discretion may direct the appointment of different independent registered accounting firm at any time during the year if the audit committee determines that such a change would be in the best interests of the company and its stockholders.

Independent Registered Public Accounting Firm’s Fees

The following table represents aggregate fees billed to us for services related to the fiscal year ended December 31, 2022, by Ernst & Young LLP, our independent registered public accounting firm.


	Year Ended December 31, 2022

All Other Fees		—
Total	$	772,000

(1)

Audit Fees consist of fees billed for professional services performed by Ernst & Young LLP for the audit of our annual financial statements, quarterly reviews of our financial statements, services related to proposed registered stock offerings, consents and review of documents filed with the SEC, and related services that are normally provided in connection with statutory and regulatory filings or engagements.

The audit committee has considered whether the provision of non-audit services is compatible with maintaining the independence of Ernst & Young LLP, and has concluded that the provision of such services is compatible with maintaining the independence of our auditors.

Pre-Approval Policies and Procedures

Our audit committee has established a policy that all audit and permissible non-audit services provided by our independent registered public accounting firm will be pre-approved by the audit committee, and all such services were pre-approved in accordance with this policy during the fiscal year ended December 31, 2022. These services may include audit services, audit-related services, tax services and other services. The audit committee considers whether the provision of each non-audit service is compatible with maintaining the independence of our auditors. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. Our independent registered public accounting firm and management are required to periodically report to the audit committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date.

Vote Required; Recommendation of the Board of Directors

The affirmative vote of the holders of a majority in voting power of the votes cast affirmatively or negatively on the proposal will be required to ratify the selection of Ernst & Young LLP, meaning the number of shares voted “For” the proposal must exceed the number of shares voted “Against” the proposal. Abstentions will not be counted toward the tabulation of votes cast on this proposal and will have no effect on the proposal. The approval of Proposal 2 is a routine proposal on which a broker or other nominee has discretionary authority to vote. Accordingly, no broker non-votes will likely result from this proposal.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE RATIFICATION OF THE SELECTION OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023. PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE SO VOTED UNLESS STOCKHOLDERS SPECIFY OTHERWISE.

PROPOSAL 3:

Approval of Amendment to our Amended and Restated Certification of Incorporation to Limit the Liability of Certain Officers of the COMPANY

Background

The State of Delaware, which is Phathom’s state of incorporation, recently enacted legislation that enables Delaware companies to limit the liability of certain officers in limited circumstances under Section102(b)(7) of the Delaware General Corporation Law (“DGCL”). Amended DGCL Section 102(b)(7) only permits exculpation for direct claims brought by stockholders for breach of an officer’s fiduciary duty of care, including class actions, but does not eliminate officers’ monetary liability for breach of fiduciary duty claims brought by the corporation itself or for derivative claims brought by stockholders in the name of the corporation. Furthermore, the limitation on liability does not apply to breaches of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit.

The Board of Directors believes it is important to provide protection from certain liabilities and expenses that may discourage prospective or current officers from serving corporations. In the absence of such protection, qualified and officers might be deterred from serving as officers due to exposure to personal liability and the risk that substantial expense will be incurred in defending lawsuits, regardless of merit. In particular, the Board of Directors took into account the narrow class and type of claims that such officers would be exculpated from liability pursuant to amended DGCL Section 102(b)(7), the limited number of Phathom officers that would be impacted, and the benefits the Board of Directors believes would accrue to Phathom by providing exculpation in accordance with DGCL Section 102(b)(7), including, without limitation, the ability to attract and retain key officers and the potential to reduce future litigation costs associated with frivolous lawsuits.

The Board of Directors balanced these considerations with our corporate governance guidelines and practices and determined that it is advisable and in the best interests of Phathom and our stockholders to amend the current exculpation and liability provisions in Article SEVENTH of our Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), to adopt amended DGCL Section 102(b)(7) and extend exculpation protection to our officers in addition to our directors. We refer to this proposed amendment to our Certificate of Incorporation as the “Charter Amendment” in this proxy statement.

Text of Proposed Charter Amendment

Our Certificate of Incorporation currently provides for the exculpation of directors but does not include a provision that allows for the exculpation of officers. To ensure Phathom is able to attract and retain key officers and in an effort to reduce litigation costs associated with frivolous lawsuits, we propose to amend Article SEVENTH of our Certificate of Incorporation so that it would state in its entirety as follows:

SEVENTH: Except to the extent that the General Corporation Law of the State of Delaware prohibits the elimination or limitation of liability of directors or officers for breaches of fiduciary duty, no director or officer of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director of officer, notwithstanding any provision of law imposing such liability. No amendment to or repeal of this provision shall apply to or have any effect on the liability or alleged liability of any director or officer of the Corporation for or with respect to any acts or omissions of such director or officer occurring prior to such amendment or repeal. If the General Corporation Law of the State of Delaware is amended to permit further elimination or limitation of the personal liability of directors or officers, then the liability of a director or officer, respectively, of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of the State of Delaware as so amended.

Reasons for the Proposed Charter Amendment

The Board of Directors believes it is appropriate for public companies in states that allow exculpation of officers to have exculpation clauses in their certificates of incorporation. The nature of the role of directors and officers often requires them to make decisions on crucial matters. Frequently, directors and officers must make decisions in

response to time-sensitive opportunities and challenges, which can create substantial risk of investigations, claims, actions, suits or proceedings seeking to impose liability on the basis of hindsight, especially in the current litigious environment and regardless of merit. Limiting concern about personal risk would empower both directors and officers to best exercise their business judgment in furtherance of stockholder interests. We expect our peers to adopt exculpation clauses that limit the personal liability of officers in their certificates of incorporation and failing to adopt the proposed Charter Amendment could impact our recruitment and retention of exceptional officer candidates that conclude that the potential exposure to liabilities, costs of defense and other risks of proceedings exceeds the benefits of serving as an officer of Phathom.

For the reasons stated above, on February 24, 2023, the Board of Directors determined that the proposed Charter Amendment is advisable and in the best interest of the Company and our stockholders and authorized and approved the proposed Charter Amendment and directed that it be considered at the Annual Meeting. The Board of Directors believes the proposed Charter Amendment would better position the Company to attract top officer candidates and retain our current officers and enable the officers to exercise their business judgment in furtherance of the interests of the stockholders without the potential for distraction posed by the risk of personal liability. Additionally, it would align the protections for our officers with those protections currently afforded to our directors.

The proposed Charter Amendment is not being proposed in response to any specific resignation, threat of resignation or refusal to serve by any officer.

Required Vote; Timing and Effect of the Charter Amendment; Recommendation of the Board

To be approved, this proposal requires the affirmative vote of a majority of the shares entitled to vote. Abstentions and broker non-votes will have the same effect as votes “Against” this proposal. If the proposed Charter Amendment is approved by our stockholders, it will become effective immediately upon the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, which we expect to file promptly after the Annual Meeting. Other than the replacement of the existing Article SEVENTH by the proposed Article SEVENTH, the remainder of our Amended and Restated Certificate of Incorporation will remain unchanged after effectiveness of the Charter Amendment. If the proposed Charter Amendment is not approved by our stockholders, our Amended and Restated Certificate of Incorporation will remain unchanged. In accordance with the DGCL, the Board of Directors may elect to abandon the proposed Charter Amendment without further action by the stockholders at any time prior to the effectiveness of the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, notwithstanding stockholder approval of the proposed Charter Amendment.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE approval of an amendment to the Company’s Amended and Restated Certificate of Incorporation to limit the liability of certain officers of the Company

The amounts are valued based on the aggregate grant date fair value of the stock and option awards granted in the applicable year in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or ASC 718. See Note 7 to our financial statements in our Annual Report on Form 10‑K for the year ended December 31, 2021, filed with the SEC on February 28, 2023, for a discussion of the relevant assumptions used in determining the grant date fair value pursuant to ASC 718. These amounts do not reflect whether the recipient has actually realized or will realize a financial benefit from the awards (such as by exercising stock options). With respect to the restricted stock units (“RSUs”) granted to our named executive officers in 2022 and the performance-based stock units (“PSUs”) granted to Ms. Curran and Dr. Nabulsi in 2021, the grant date fair value was determined by multiplying the closing price per share of our common stock on the date of grant by the number of RSUs or PSUs awarded. Whether, and to what extent, a named executive officer realizes a financial benefit from the awards will depend on our actual operating performance, stock price fluctuations and the named executive officer's continued employment or service.

Narrative Disclosure to Summary Compensation Table

Annual Base Salary

The compensation of our named executive officers is generally determined and approved at the time of their commencement of employment by our board of directors or the compensation committee. Additionally, our board of directors or the compensation committee periodically reviews our named executive officers’ base salaries annually and may make adjustments based on its review.

In May 2022, our Board of Directors approved merit salary increases, effective as of March 1, 2022, for each of our named executive officers as follows:


Executive	2021 Base Salary ($)	2022 Base Salary ($)
Terrie Curran	600,000	660,000

Ms. Henderson joined as our Chief Financial and Business Officer effective April 5, 2022.

Bonus Compensation

Each named executive officer is also eligible for a performance bonus based upon the achievement of certain corporate performance goals and objectives approved by our board of directors.

Bonus target amounts are set based on the executive’s total salary for the bonus year and are generally paid in the first quarter of the following year. The target levels for executive bonuses for 2022 were as follows: 65% of base salary for Ms. Curran, 50% of base salary for Dr. Nabulsi, and 45% of base salary for Ms. Henderson.

For 2022, the board of directors (considering the recommendations of the compensation committee and management) set corporate goals and milestones for the year. These goals and milestones and the proportional emphasis placed on each were set by the board of directors after considering management input and our overall strategic objectives. These goals generally related to factors such as financial targets, achievement of product development, manufacturing, and regulatory milestones, and achievement of commercial readiness objectives. The board of directors, upon recommendation of the compensation committee, determined the level of achievement of the corporate goals for the year.

All final bonus payments to our named executive officers are determined by our 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 may also vary based on other factors at the discretion of the compensation committee. For 2022, corporate objectives fell into the following three categories: regulatory, clinical and manufacturing developments (40%); commercial and launch readiness (40%), and financial goals (20%).

In evaluating management’s performance against our 2022 corporate goals, our compensation committee determined to award a corporate achievement level of 104.7% (out of a potential maximum score of 150%) relative to those goals, noting our achievements in securing our first product approvals, filing a new drug application for vonoprazan for the treatment of erosive gastroesophageal reflux disease (erosive GERD), execution and receipt of positive topline data from the primary endpoint of our Phase 3 trial studying vonoprazan as a treatment for non-erosive GERD, closing a revenue interest financing agreement providing up to $300 million in potential financing, and making substantial progress towards resolving the unanticipated nitrosamine impurity issue including, without limitation, completing root cause investigations and implementing mitigation measures to reduce and/or inhibit nitrosamine growth in vonoprazan drug product.

Both qualitative and quantitative guidelines were established for purposes of evaluating performance relative to the corporate objectives during 2022. These performance objectives were used as a guide by the compensation committee in subjectively determining overall corporate performance as they represented those areas in which the named executive officers and our employees generally were expected to focus their efforts.

Equity-Based Incentive Awards

Our equity-based incentive awards are designed to align our interests and the interests of our stockholders with those of our employees and consultants, including our named executive officers. Our board of directors or the compensation committee approves equity grants. We grant equity awards under our 2019 Incentive Award Plan, or 2019 Plan.

Other Elements of Compensation

Perquisites, Health, Welfare and Retirement Benefits

Our named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision, group life, disability, accidental death and dismemberment insurance plans, and 401(k) plan, in each case on generally the same basis as all of our other employees. We also pay a portion of the premiums for term life insurance and disability insurance for all of our employees, including our named executive officers. Our board of

directors may elect to adopt additional benefit plans, qualified or non-qualified, in the future if it determines that doing so is in our best interests.

We generally do not provide other perquisites or personal benefits to our named executive officers.

401(k) Plan

We maintain a 401(k) plan intended to qualify as a tax-qualified plan under Section 401 of the U.S. Internal Revenue Code of 1986, as amended, which our US-based named executive officers are eligible to participate in on the same basis as our other employees. The 401(k) plan allows us to make discretionary matching contributions. In July 2022, our board of directors approved a discretionary match for the first half of 2022, which was equal to 75% of each employee’s contribution from January 1, 2022 through June 30, 2022, up to the IRS maximum contribution amount of $20,500. In January 2023, our board of directors approved a discretionary match for the second half of 2021, which was equal to 75% of each employee’s annual contribution, up to the IRS maximum contribution amount of $20,500, less the matching contribution made for the first half of 2022. Each 2022 match under our 401(k) plan was made in the form of fully vested shares of our common stock.

Termination and Change in Control Benefits

Our named executive officers may become entitled to certain benefits or enhanced benefits in connection with certain qualifying terminations and/or a change in control of our company. The employment letters with Ms. Curran, Dr. Nabulsi and Ms. Henderson entitle them to certain accelerated vesting of equity awards, as well as certain other benefits, upon a qualifying termination and/or in connection with a change in control of our company. For additional discussion, please see “Employment Letters with Our Named Executive Officers” above. The restricted stock held by Dr. Nabulsi will also vest in full or in part upon a qualifying termination and/or in connection with a change in control of our company, as further described in footnote (7) to the “Outstanding Equity Awards at Fiscal Year End” table above. In addition, the PSUs granted to Ms. Curran and Dr. Nabulsi will vest in full upon a change in control as defined in the 2019 Plan.

In the event of a change in control where the acquirer does not assume awards granted our equity plans, awards issued under these plans shall be subject to accelerated vesting such that 100% of the awards will become vested and exercisable or payable, as applicable, and which may be subject to such terms and conditions as apply generally to holders of common stock under the change in control documents.

Takeda Agreements

License Agreement and Clinical Manufacturing and Supply Agreement

On May 7, 2019, we and Takeda, one of our 5% stockholders, entered into a license agreement, or the Takeda License, and a clinical manufacturing and supply agreement. Pursuant to the Takeda License, Takeda granted us an exclusive, sublicensable (with Takeda’s reasonable consent) license under certain patents and know how relating to vonoprazan and owned or controlled by Takeda during the term of the Takeda License to commercialize vonoprazan products using specified formulations for all human therapeutic uses in the United States, Europe and Canada, and a non-exclusive license under such patents and know how to develop and manufacture such vonoprazan products anywhere in the world (subject to Takeda’s consent as to each country) for the purposes of commercializing the vonoprazan products in the United States, Europe and Canada. We granted Takeda a non-exclusive, royalty-free, sublicensable license under our rights in any patents and know-how that are necessary or useful to enable Takeda to develop and manufacture vonoprazan products anywhere in the world for the purposes of commercialization outside United States, Europe and Canada. We also granted Takeda an exclusive, royalty-free license under our rights in certain patents and know-how owned or controlled by us and necessary for the exploitation of vonoprazan products, in each case for Takeda to commercialize any vonoprazan product outside of the United States, Canada, and Europe and for purposes other than human therapeutic use.

During the term of the Takeda License, we and our affiliates are not permitted to commercialize any pharmaceutical product, other than vonoprazan, that treats acid-related disorders, except for certain generic and OTC competing products in specified circumstances. We will be responsible, at our cost, for the development, manufacture and commercialization of the vonoprazan products. We are required to use commercially reasonable efforts to develop and commercialize the vonoprazan products in our licensed territory.

Under the Takeda License, Takeda has the sole right and authority, with our input, to prepare, file, prosecute, and maintain all Takeda and joint patents on a worldwide basis at its own cost. We are responsible, at our cost, for preparing, filing, prosecuting, and maintaining patents on inventions made solely by us in connection with vonoprazan, subject to input from Takeda. We have the first right to enforce the licensed patent rights with respect to certain infringing products in the United States, Europe and Canada.

We paid Takeda upfront consideration consisting of a cash payment of $25.0 million, 1,084,000 shares of common stock and a warrant to purchase 7,588,000 shares of common stock, or the Takeda Warrant. We agreed to make milestone payments to Takeda upon achieving certain tiered aggregate annual net sales of licensed products in the United States, Europe and Canada up a total maximum milestone amount of $250.0 million. We also agreed to make tiered royalty payments in the low double digits to the mid-teens on net sales of licensed products, subject to specified offsets and reductions. Royalties will be payable, on a product-by-product and country-by-country basis from the first commercial sale of such product in such country, until the latest of expiration of the licensed patents covering the applicable product, expiration of regulatory exclusivity in such country, or 15 years following first commercial sale in such country.

The Takeda License will continue until the expiration of the obligation to pay royalties in all countries and on all products. We may terminate the Takeda License in its entirety without cause upon six months’ prior written notice. We and Takeda may terminate the Takeda License in the case of the other party’s insolvency, or upon prior written notice within a specified time period for the other party’s material uncured breach. Takeda may terminate the Takeda License in its entirety if we challenge the licensed patents, or if we assist any third party in challenging such patents.

In connection with the Takeda License, we entered into a clinical manufacturing and supply agreement with Takeda whereby Takeda provided certain quantities of vonoprazan.

In connection with the Takeda License, we also (i) entered into a Stock Issuance Agreement with Takeda, pursuant to which we issued Takeda 1,084,000 shares of our common stock, (ii) issued a warrant, or the Takeda Warrant, to purchase 7,588,000 shares of common stock at an exercise price of $0.00004613 per share and (iii) granted to Takeda a right, or the Takeda Warrant Right, to receive an additional common stock warrant upon the closing of this offering if Takeda’s fully-diluted ownership represents less than a specified percentage of our fully-diluted capitalization, including shares issuable upon conversion of outstanding convertible promissory notes, calculated immediately prior to the closing of our initial public offering, each as partial consideration under the Takeda License. The Takeda Warrant would have expired ten years from its date of issuance, subject to its earlier termination upon the completion of certain mergers, acquisitions and similar transactions. The Takeda Warrant Right expired upon the closing of our initial public offering in October 2019.

Commercial Supply Agreement

On May 5, 2020, the Company entered into a Commercial Supply Agreement (the “Commercial Supply Agreement”) with Takeda, pursuant to which Takeda will supply commercial quantities of vonoprazan bulk drug product. Pursuant to the Commercial Supply Agreement, Takeda has agreed to supply the Company with, and the Company has agreed to purchase from Takeda, certain quantities of vonoprazan bulk drug product according to approved specifications at a fixed price per batch of bulk drug product in order to commercialize vonoprazan in accordance with the Takeda License. Unless terminated earlier, the term of the Commercial Supply Agreement extends for a period of two years from the date the Company places an order for bulk drug product for the first commercial launch of vonoprazan in any jurisdiction in the licensed territory, provided that this two-year period will expire no later than December 31, 2023. The Commercial Supply Agreement will terminate immediately upon the termination of the Takeda License in accordance with its terms.

Temporary Services Agreement

In connection with the Takeda License, the Company entered into a temporary services agreement (the “Temporary Services Agreement”) with Takeda on November 24, 2020. Pursuant to the Temporary Services Agreement, Takeda agreed to provide or procure the provision of services related to the ongoing clinical development of vonoprazan.

The Temporary Services Agreement will terminate immediately upon termination of the Takeda License in accordance with its terms.

Policies and Procedures for Related Person Transactions

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

STOCKHOLDER PROPOSALS

Proposals of stockholders intended to be presented at our annual meeting of stockholders to be held in 2024, including nominations of any person for election to our board of directors, must be received by us no later than December 15, 2023, which is 120 days prior to the one-year anniversary of the mailing date of the proxy statement for the 2023 annual meeting, in order to be included in our proxy statement and form of proxy card relating to that meeting, unless the date of the 2024 annual meeting of stockholders is changed by more than 30 days from the anniversary of our 2023 annual meeting, in which case the deadline for such proposals will be a reasonable time before we begin to print and send our proxy materials. These proposals must comply with the requirements as to form and substance established by the SEC in Rule 14a-8 of the Exchange Act for such proposals in order to be included in the proxy statement.

In addition, our amended and restated bylaws establish an advance notice procedure with regard to certain matters, including stockholder proposals and nominations of any person for election to our board of directors not included in our proxy statement, to be brought before an annual meeting of stockholders. In general, notice that meets the requirements set forth in our amended and restated bylaws must be received at our principal executive offices not less than 90 calendar days nor more than 120 calendar days prior to the first anniversary of the preceding year’s annual meeting. Therefore, to be presented at our 2024 annual meeting of stockholders, such a proposal must be received by us no earlier than January 26, 2024, and no later than February 25, 2024. However, if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice must be received no earlier than the close of business on the 120th day prior to such annual meeting and not later than the later of the close of business on the 90th calendar day prior to such annual meeting and the close of business on the tenth day following the day on which public disclosure of the date of such annual meeting was first made. If the stockholder fails to give notice by these dates, then the persons named as proxies in the proxies solicited by the board of directors for the 2024 annual meeting may exercise discretionary voting power regarding any such proposal. Stockholders are advised to review our amended and restated bylaws which also specify requirements as to the form and content of a stockholder’s notice.

In addition to satisfying the foregoing requirements under our amended and restated bylaws, to comply with the universal proxy rules (once they become effective), stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 26, 2024, which is 60 days prior to the one-year anniversary of the date of the 2023 annual meeting. We intend to file a proxy statement and WHITE proxy card with the SEC in connection with our solicitation of proxies for our 2024 annual meeting of stockholders.

ANNUAL REPORT

Any person who was a beneficial owner of our common stock on the record date may request a copy of our Annual Report on Form 10-K for the year ended December 31, 2022, and it will be furnished without charge upon receipt of a written request identifying the person so requesting a report as a stockholder of our company at such date. Requests should be directed to Phathom Pharmaceuticals, Inc., 100 Campus Drive, Suite 102, Florham Park, NJ 07932, Attention: Corporate Secretary. The Company makes available free of charge on its website all of its filings that are made electronically with the SEC, including Forms 10-K, 10-Q and 8-K. These materials can be found at www.phathompharma.com in the “Investors & Media” section. Our Annual Report on Form 10-K does not constitute, and should not be considered, a part of this proxy solicitation material.

STOCKHOLDERS SHARING THE SAME ADDRESS

The rules promulgated by the SEC permit companies, brokers, banks or other intermediaries to deliver a single copy of proxy materials, or, where applicable, a Notice of Internet Availability of Proxy Materials, to households at which two or more stockholders reside. Each stockholder, however, still receives a separate proxy card if he or she receives paper copies. This practice, known as “householding,” is designed to reduce duplicate mailings and save significant printing and postage costs as well as natural resources. Stockholders sharing an address who have been previously notified by their broker, bank or other intermediary and have consented to householding will receive only one copy of our proxy statement and annual report or Notice of Internet Availability of Proxy Materials. If you would like to opt out of this practice for future mailings and receive a separate proxy statement and annual report or Notice of Internet Availability of Proxy Materials for each stockholder sharing the same address, please contact your broker, bank or other intermediary. You may also obtain a separate proxy statement or annual report or Notice of Internet Availability of Proxy Materials without charge by sending a written request to Phathom Pharmaceuticals, Inc., 100 Campus Drive, Suite 102, Florham Park, NJ 07932 Attention: Corporate Secretary or by calling (877) 742-8466. We will promptly send additional copies of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials upon receipt of such request. Stockholders sharing an address that are receiving multiple copies of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials can request delivery of a single copy of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials by contacting their broker, bank or other intermediary or sending a written request to Phathom Pharmaceuticals, Inc. at the address above or by calling (877) 742-8466.

OTHER MATTERS

We do not know of any business other than that described in this proxy statement that will be presented for consideration or action by the stockholders at the annual meeting. If, however, any other business is properly brought before the meeting, shares represented by proxies will be voted in accordance with the best judgment of the persons named in the proxies or their substitutes. All stockholders are urged to vote via the Internet, by telephone or to complete, sign and return a completed proxy card as soon as possible.
