PROXY STATEMENT

FOR THE 2023 ANNUAL MEETING OF STOCKHOLDERS

GENERAL INFORMATION

When are this proxy statement and the accompanying materials scheduled to be sent to stockholders?

We have elected to provide access to our proxy materials to our stockholders via the Internet. Accordingly, on or about April 26, 2023, we are mailing a Notice of Internet Availability of Proxy Materials (the “Notice”). Our proxy materials, including the Notice of 2023 Annual Meeting of Stockholders, this proxy statement, and the accompanying proxy card or, for shares held in street name (i.e., held for your account by a broker or other nominee), a voting instruction form, and the 2022 Annual Report to Stockholders (the “2022 Annual Report”), will be mailed or made available to stockholders on the Internet on or about the same date.

Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

Pursuant to rules adopted by the SEC, for most stockholders, we are providing access to our proxy materials over the Internet rather than printing and mailing our proxy materials. We believe following this process will expedite the receipt of such materials and will help lower our costs and reduce the environmental impact of our annual meeting materials. Therefore, the Notice was mailed to holders of record and beneficial owners of our common stock starting on or about April 26, 2023. The Notice provides instructions as to how stockholders may access and review our proxy materials, including the Notice of 2023 Annual Meeting of Stockholders, this proxy statement, the proxy card and our 2022 Annual Report, on the website referred to in the Notice or, alternatively, how to request that a copy of the proxy materials, including a proxy card, be sent to them by mail. The Notice also provides voting instructions. In addition, stockholders of record may request to receive the proxy materials in printed form by mail or electronically by e-mail on an ongoing basis for future stockholder meetings. Please note that, while our proxy materials are available at the website referenced in the Notice, and our Notice of 2023 Annual Meeting of Stockholders, this proxy statement and our 2022 Annual Report are available on our website, no other information contained on either website is incorporated by reference in or considered to be a part of this proxy statement.

Who is soliciting my vote?

Our board of directors is soliciting your vote for the Annual Meeting.

When is the record date for the Annual Meeting?

The record date for determination of stockholders entitled to vote at the Annual Meeting is the close of business on April 14, 2023.

How many votes can be cast by all stockholders?

There were 59,156,430 shares of our common stock, par value $0.0001 per share, outstanding on the record date, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder.

Where will the Annual Meeting be held this year?

The Annual Meeting will be held virtually. The virtual format will enable us to provide access to the Annual Meeting for our stockholders regardless of geographic location. We are committed to ensuring that stockholders will be afforded the same rights and opportunities to participate as they would at an in-person meeting. In order to attend the virtual Annual Meeting, vote your shares and ask questions, stockholders of record as of April 14, 2023 can access the meeting at www.virtualshareholdermeeting.com/PLRX2023.

To join the Annual Meeting, you will need to have your 16-digit control number, which is included on the Notice and your proxy card. In the event that you do not have a control number, please contact your broker, bank, or other nominee as soon as possible, so that you can be provided with a control number and gain access to the meeting.

If you are logged in as a stockholder at the virtual Annual Meeting, you will have an opportunity to submit questions live via the Internet during a designated portion of the virtual Annual Meeting. Once you are logged in, type your question into the question box and click “submit.” Subject to time constraints, we intend to answer questions pertinent to the Company and meeting matters

TABLE OF CONTENTS

submitted by stockholders during the Annual Meeting that comply with our rules of conduct for the Annual Meeting, which will be posted on the meeting website during the meeting.

The meeting will begin promptly at 8:30 a.m. Pacific Time on Wednesday, June 7, 2023. You may access the meeting platform beginning at 8:15 a.m. Pacific Time, and we encourage you to join in advance of the meeting start time to allow sufficient time to log in and confirm your connection and audio are working properly.

Even if you plan to attend the Annual Meeting virtually, we recommend that you also vote by proxy as described herein so that your vote will be counted if you decide not to attend the Annual Meeting.

What are the proposals to be voted on this year?

The purpose of the Annual Meeting is the following:


1			To elect three class III directors named in this proxy statement to our board of directors, to serve until the 2026 Annual Meeting of Stockholders and until their successor has been duly elected and qualified, or until his or her earlier death, resignation, or removal;
2			To approve, by non-binding advisory vote, the resolution approving named executive officer compensation (“say-on-pay”);
3			To ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; and
4			To transact any other business properly brought before the Annual Meeting or any adjournment or postponement of the Annual Meeting.

How do I vote?

If you are a stockholder of record, there are several ways for you to vote your shares.


•Online during the Annual Meeting. You may vote during the virtual Annual Meeting by following the instructions available at www.virtualshareholdermeeting.com/PLRX2023. If you hold your shares through a bank or broker and wish to vote at the virtual Annual Meeting, you must obtain a valid proxy from the firm that holds your shares. To join the Annual Meeting, you will need to have your 16-digit control number, which is included on the Notice and your proxy card. In the event that you do not have a control number, please contact your broker, bank, or other nominee as soon as possible, so that you can be provided with a control number and gain access to the meeting.
•By Internet or Telephone prior to the Annual Meeting. You can vote by proxy over the Internet or by telephone by following the instructions provided in the Notice. In order to be counted, proxies submitted by Internet or by telephone must be received by the cutoff time of 11:59 p.m. Eastern Time on June 6, 2023.
•By Mail prior to the Annual Meeting. If you requested printed copies of the proxy materials by mail, you can vote by mailing your proxy as described in the proxy materials. Proxies submitted by mail must be received before the start of the Annual Meeting.

If you complete and submit your proxy before the Annual Meeting, the persons named as proxies will vote the shares represented by your proxy in accordance with your instructions.

If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in your proxy and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed proxy card or otherwise vote without marking specific voting selections, your shares will be voted as the board of directors recommends: “For” the election of three (3) class III directors (Proposal No. 1); “For” the approval, by non-binding advisory vote, of the resolution approving named executive officer compensation (say-on-pay) (Proposal No. 2); “For” the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023 (Proposal No. 3); and in accordance with the best judgment of the proxy holders for any other matters properly brought before the meeting, if any.

TABLE OF CONTENTS

How do I revoke my proxy?

You may revoke your proxy by (1) following the instructions on the Notice and entering a new vote by mail that we receive before the start of the Annual Meeting or over the Internet by the cutoff time of 11:59 p.m. Eastern Time on June 6, 2023, (2) attending and voting at the virtual Annual Meeting (although attendance at the virtual Annual Meeting will not in and of itself revoke a proxy), or (3) by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with our Corporate Secretary. Any written notice of revocation or subsequent proxy card must be received by our proxy tabulator prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be delivered by mail to the Proxy Tabulator for Pliant Therapeutics, Inc. at Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717.

If a broker, bank, or other nominee holds your shares, you must contact such broker, bank, or nominee in order to find out how to change your vote.

How is a quorum reached?

Our Amended and Restated Bylaws (“bylaws”) provide that a majority of the shares entitled to vote, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting.

Under the General Corporation Law of the State of Delaware, shares that are voted “abstain” or “withheld” and broker “non-votes,” which are described more fully below, are counted as present for purposes of determining whether a quorum is present at the Annual Meeting. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

How many votes are required to approve the proposals?

Under our bylaws, any proposal other than an election of directors is decided by a majority of the votes properly cast for and against such proposal, except where a larger or different vote is required by law or by our Amended and Restated Certificate of Incorporation (“certificate of incorporation”) or bylaws. Accordingly, this is the voting standard that will apply for Proposals 2 and 3.

Abstentions and broker “non-votes” are not included in the tabulation of the voting results on any such proposal and, therefore, do not have an impact on such proposals. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting authority with respect to that item and has not received instructions from the beneficial owner.

To be elected, the directors nominated via Proposal 1 must receive a plurality of the votes properly cast, meaning that the director nominees receiving the most votes will be elected. Shares voting “withheld” have no effect on the election of directors.

What is a broker non-vote?

If your shares are held in “street name” by a brokerage firm, your brokerage firm is required to vote your shares according to your instructions. If you do not give instructions to your brokerage firm, the brokerage firm will still be able to vote your shares with respect to certain “discretionary” items but will not be allowed to vote your shares with respect to “non-discretionary” items. The election of directors and Proposal No. 2 are “non-discretionary” items. If you do not instruct your broker how to vote with respect to these proposals, your broker may not vote for such proposals, and a broker “non-vote” will occur. Proposal No. 3, the ratification of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023, is considered to be a discretionary item, and your brokerage firm will be able to vote on this proposal even if it does not receive instructions from you.

Who pays the cost for soliciting proxies?

We are making this solicitation and will pay the entire cost of preparing and distributing the Notice and our proxy materials and soliciting votes. If you choose to access the proxy materials or vote over the Internet, you are responsible for any Internet access charges that you may incur. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise. Proxy solicitation expenses that we will pay include those for preparation, mailing, returning, and tabulating the proxies.

How can I know the voting results?

We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

TABLE OF CONTENTS

PROPOSAL NO. 1 – ELECTION OF CLASS III DIRECTORS

Our board of directors currently consists of ten members. In accordance with the terms of our certificate of incorporation and bylaws, our board of directors is divided into three classes, class I, class II and class III, with members of each class serving staggered three-year terms. The members of the classes are divided as follows:


•the class I directors are Hoyoung Huh, M.D., Ph.D., Darren Cline, MBA, and David Pyott, MA, MBA, with current terms expiring at the Annual Meeting of Stockholders to be held in 2024;
•the class II directors are John Curnutte, M.D., Ph.D., Kate Knobil, M.D., Thomas McCourt and Smital Shah, MBA, with current terms expiring at the Annual Meeting of Stockholders to be held in 2025; and
•the class III directors standing for election are Bernard Coulie, M.D., Ph.D., Gayle Crowell and Suzanne Bruhn, Ph.D., with current terms expiring at the Annual Meeting.

Upon the 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.

Our board of directors has nominated each of Bernard Coulie, M.D., Ph.D., Gayle Crowell and Suzanne Bruhn, Ph.D., to stand for election as class III directors. Drs. Coulie and Bruhn and Ms. Crowell were elected as members of our board prior to our initial public offering, pursuant to a voting agreement entered into with certain of our stockholders that terminated upon completion of our initial public offering in June 2020. The nominees are currently directors and have indicated a willingness to continue to serve as directors, if elected. If the nominees become unable or unwilling to serve, however, the proxies may be voted for a substitute nominee selected by our board of directors.

Ms. Crowell received an undergraduate degree in education from the University of Nevada at Reno. We believe Ms. Crowell is qualified to serve on our board of directors based on her extensive leadership experience as a board member and senior executive of other private and public companies.

Suzanne Bruhn, Ph.D., has served as a member of our board of directors since July 2016. Dr. Bruhn currently serves as President and Chief Executive Officer of Tiaki Therapeutics, a preclinical biotechnology company, since May 2019.

She holds a B.S. in Chemistry from Iowa State University and a Ph.D. in Chemistry from Massachusetts Institute of Technology and completed her postdoctoral fellowship in the department of human genetics at Harvard Medical School. We believe Dr. Bruhn is qualified to serve on our board of directors based on her extensive expertise and experience in the biopharmaceutical industry, including her expertise in the development of treatments for rare diseases and diseases involving fibrosis.

The proxies will be voted in favor of the above nominees unless a contrary specification is made in the proxy. The nominees have consented to serve as our directors if elected. However, if the nominees are unable to serve or for good cause will not serve as a director, the proxies will be voted for the election of such substitute nominee as our board of directors may designate.

The board of directors recommends voting “FOR” the election of Bernard Coulie, M.D., Ph.D., Gayle Crowell and Suzanne Bruhn, Ph.D. as the class III directors, to serve for a three-year term ending at the Annual Meeting of Stockholders to be held in 2026.

CORPORATE GOVERNANCE

Director Nomination Process

Our Nominating and Corporate Governance Committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our board of directors, and recommending such persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.

The process followed by our Nominating and Corporate Governance Committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by management, recruiters, members of the committee and our board of directors. The qualifications, qualities, and skills that our Nominating and Corporate Governance Committee believes must be met by a committee-recommended nominee for a position on our board of directors are as follows:


•The nominee shall have experience at a strategic or policymaking level in a business, government, non-profit or academic organization of high standing.
•The nominee shall be highly accomplished in his or her respective field, with superior credentials and recognition.
•The nominee shall be well regarded in the community and shall have a long-term reputation for the high ethical and moral standards.
•The nominee shall have sufficient time and availability to devote to the affairs of the Company, particularly in light of the number of boards of directors on which such nominee may serve.
•To the extent such nominee serves or has previously served on other boards, the nominee shall have a demonstrated history of actively contributing at board meetings.

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates. Any such proposals must be submitted to our Corporate Secretary at the address below no later than the close of business on the 90th day nor earlier than the 120th day prior to the one-year anniversary of the date of the preceding year’s annual meeting and should include the biographical, background, and other information required by our bylaws, including beneficial ownership and other contractual interests with respect to the Company. In addition to other information and materials required by our bylaws, the proposal must include a questionnaire with respect to the background and qualifications of the nominee, and a written representation and agreement, in each case, completed by the nominee in the form required by the Company. The stockholder giving notice must request these documents in writing from the Company prior to submitting notice, and the Corporate Secretary of the Company will provide these documents to the stockholder no later than ten (10) days after receiving such request. Stockholder proposals and requests for required documentation should be addressed to Pliant Therapeutics, Inc., 260 Littlefield Avenue, South San Francisco, CA 94080, Attention: Corporate Secretary. In addition to the information required above, the board of directors may request that any stockholder giving notice and any proposed nominee furnish such additional information as may be reasonably required by the board of directors and to submit to interviews with the board of directors or any committee thereof. Assuming that all required information and materials have been provided on a timely basis in accordance with our bylaws, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the Nominating and Corporate Governance Committee. If our board of directors determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting of stockholders. See “Stockholder Proposals” for a discussion of submitting stockholder proposals.

Director Independence

In accordance with applicable listing standards of Nasdaq Stock Market LLC (“Nasdaq”), our board of directors has determined that all members of the board of directors, except Dr. Coulie, are independent directors, including for purposes of the rules of Nasdaq and the SEC. Dr. Coulie is not an independent director under these rules because he is the President and Chief Executive Officer of the Company.

Nominating and Corporate Governance Committee

Gayle Crowell, Suzanne Bruhn, Ph.D., Kate Knobil, M.D. and Hoyoung Huh, M.D., Ph.D. currently serve on the Nominating and Corporate Governance Committee, which is chaired by Ms. Crowell. Our board of directors has determined that each member of the Nominating and Corporate Governance Committee is “independent” as defined in the applicable Nasdaq rules.

Additionally, in selecting nominees for directors, the Nominating and Corporate Governance Committee will review candidates recommended by stockholders in the same manner and using the same general criteria as candidates recruited by the committee and/or recommended by our board of directors. Any stockholder who wishes

TABLE OF CONTENTS

to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described above under the heading “Director Nomination Process” and later in this proxy statement under the heading “Stockholder Proposals.”

Identifying and Evaluating Director Nominees. Our board of directors is responsible for filling vacancies on our board of directors and for nominating candidates for election by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. The Nominating and Corporate Governance Committee recommends director candidates to the board of directors for approval and nominations are then made by the full board of directors. Members of the board of directors and management are requested to take part in the process as appropriate.

The Nominating and Corporate Governance Committee may identify candidates for director nominees in consultation with management, through the use of search firms or other advisors, through the recommendations submitted by stockholders or through such other methods as the Nominating and Corporate Governance Committee deems to be helpful to identify candidates. Once candidates have been identified, the Nominating and Corporate Governance Committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the Nominating and Corporate Governance Committee deems to be appropriate in the evaluation process. The Nominating and Corporate Governance Committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors.

Although we do not have a formal policy with regard to the consideration of diversity in identifying director candidates, overall board diversity of industry background, race and gender is generally among the factors considered. Our priority in selection of board members is identification of members who will further the interests of our stockholders through consideration of a number of facts and circumstances, including among other things, the skills of the prospective director candidate, his or her depth and breadth of business experience or other background characteristics, his or her independence and the needs of the board of directors.

Based on the results of the evaluation process, the Nominating and Corporate Governance Committee recommends candidates for the board of directors’ approval to fill a vacancy or as director nominees for election to the board of directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting.

Research and Development Committee

In addition to our three standing committees of the board of directors described above, we have also established a Research and Development Committee. John Curnutte, M.D., Ph.D. and Kate Knobil, M.D. serve on the Research and Development Committee, which is chaired by Dr. Knobil. The purpose of the Research and Development Committee is to assist us in evaluating research and development issues and decisions and to provide to the board of directors a detailed perspective on research and development efforts. The Research and Development Committee operates in an advisory capacity and the board of directors has not delegated any of its decision-making authority to this Committee.

Board and Committee Meetings Attendance

The full board of directors met 21 times during 2022. During 2022, the Audit Committee met five times, the Compensation Committee met nine times, and the Nominating and Corporate Governance Committee met six times.

During 2022, each member of the board of directors attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings of the board of directors (held during the period for which such person was a director) and (ii) the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served).

We encourage our directors to attend our annual stockholder meetings. Each member of our board of directors was in attendance at the 2022 Annual Meeting of Stockholders, which was held virtually.

Policy on Trading, Pledging and Hedging of Company Stock

Our insider trading policy expressly prohibits our executive officers, directors and designated employees and consultants from engaging in certain prohibited transactions, including short sales, purchases or sales of derivative securities or hedging transactions, the use of our securities as collateral in a margin account, and pledging of our securities.

Code of Business Conduct and Ethics

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. A current copy of the code is posted on the Investors & Media–Corporate Governance section of our website, which is located at https://pliantrx.com. If we make any substantive amendments to, or grant any waivers from, the Code of Business Conduct and Ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.

Board Leadership Structure

Hoyoung Huh, M.D., Ph.D. is our Lead Director and Bernard Coulie, M.D., Ph.D. is our President and Chief Executive Officer, hence the roles of Lead Director or Chairman and the Chief Executive Officer and President are separated. We believe that separating these positions allows our Chief Executive Officer to focus on setting the overall strategic direction of the company, expanding the organization to deliver on our strategy and overseeing our day-to-day business, while allowing a lead director of the board to lead the board of directors in its fundamental role of providing strategic advice. Our board of directors recognizes the time, effort, and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our lead director, particularly as the board of directors’ oversight responsibilities continue to grow. While our bylaws and corporate governance guidelines do not require that our lead director and chief executive officer positions be separate, our board of directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

The Board’s Role in Risk Oversight

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations, strategic direction and intellectual property as more fully discussed under the heading “Risk Factors” in our most recent Annual Report on Form 10-K. Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of the management of risks confronting the Company over the short term, intermediate term and long term. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The role of the board of directors in overseeing the management of our risks is conducted primarily through committees of the board of directors, as disclosed in the descriptions of each of the committees above and in the charters of each of the committees. The full board of directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) regularly discusses with management our major risk exposures, their potential impact on us, and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chairperson of the relevant committee reports on substantive discussions or decisions to the full board of directors during the committee reports

TABLE OF CONTENTS

portion of the next board meeting. This enables the board of directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Cybersecurity

We use security monitoring technologies to monitor and respond to cyber threats. We also regularly engage independent third-party security auditors to test our systems and controls against relevant security standards and regulations. Information security awareness training is mandatory for our employees. Our board of directors is briefed several times each year by management on cybersecurity matters and developments relevant to the Company.

Communication with the Directors of Pliant

Any interested party with concerns about our Company may report such concerns to the board of directors or the lead director of our board of directors and Nominating and Corporate Governance Committee, by submitting a written communication to the attention of such director at the following address:

c/o Pliant Therapeutics, Inc.

260 Littlefield Avenue

South San Francisco, CA 94080

You may submit your concern anonymously or confidentially by postal mail. You may also indicate whether you are a stockholder, customer, supplier, or other interested party.

A copy of any such written communication may also be forwarded to the Company's legal counsel and a copy of such communication may be retained for a reasonable period of time. The director may discuss the matter with the Company’s legal counsel, with independent advisors, with non-management directors, or with the Company’s management, or may take other action or no action as the director determines in good faith, using reasonable judgment, and applying his or her own discretion.

Communications may be forwarded to other directors if they relate to important substantive matters and include suggestions or comments that may be important for other directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances, and matters as to which we tend to receive repetitive or duplicative communications.

The Audit Committee oversees the procedures for the receipt, retention, and treatment of complaints received by the Company regarding accounting, internal accounting controls, or audit matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. The Nominating and Corporate Governance Committee oversees the procedures for the receipt, retention, and treatment of non-financial legal and compliance complaints received by the Company and the confidential, anonymous submission by employees of concerns of this nature. The Company has also established a toll-free telephone number for the reporting of such activity, which is (855) 722-2298.

Board and Committee Evaluations

The Nominating and Corporate Governance Committee oversees the annual board and committee evaluation process. Generally, the board and each committee conduct self-evaluations through a variety of means, such as written questionnaires or interviews completed by each director and committee member. The anonymous responses are summarized and provided to the board and each committee at their next meetings in order to facilitate an examination and discussion by the board and each committee of the effectiveness of the board and committees, board and committee structure and dynamics, and areas for possible improvement. The Nominating and Corporate Governance Committee establishes the board and committee evaluation process each year. An independent third party assists in the evaluation process periodically.

Non-Employee Director Compensation Policy

Our board of directors has adopted a non-employee director compensation policy. The policy is designed to enable us to attract and retain, on a long-term basis, highly qualified non-employee directors. Under the policy, our non-employee directors will be eligible to receive cash retainers (which will be prorated for partial years of service) and equity awards as set forth below:

TABLE OF CONTENTS


Annual Retainer for Board Membership
Annual service on the board of directors	$	40,000
Additional retainer for annual service as non-executive chairperson or lead director of the board of directors	$	30,000
Additional Annual Retainer for Committee Membership
Annual service as audit committee chairperson	$	15,000
Annual service as member of the audit committee (other than chair)	$	7,500
Annual service as compensation committee chairperson	$	10,000
Annual service as member of the compensation committee (other than chair)	$	5,000
Annual service as nominating and corporate governance committee chairperson	$	8,000
Annual service as member of the nominating and corporate governance committee (other than chair)	$	4,000
Annual service as research and development committee chairperson	$	8,000
Annual service as member of the research and development committee (other than chair)	$	4,000

In addition, our policy provides that, upon initial election or appointment to our board of directors, each new non-employee director will be granted a one-time grant of a non-statutory stock option with a target grant date fair value of $500,000, based on the average closing market price calculated over a trailing 30-day period, to purchase shares of our common stock on the date of such director’s election or appointment to the board of directors, (the “Director Initial Grant”). The Director Initial Grant will vest in substantially equal monthly installments over three years. On the date of each annual meeting of stockholders of our company, each non-employee director who will continue as a non-employee director following such meeting will be granted an annual award of a non-statutory stock option with a target grant date fair value of $250,000, based on the average closing market price calculated over a trailing 30-day period, to purchase shares of our common stock (the “Director Annual Grant”). The Director Annual Grant will vest in equal quarterly installments over one year and 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. The Director Initial Grant and Director Annual Grant are subject to full acceleration of vesting upon the sale of our company.

The aggregate amount of compensation, including both equity compensation and cash compensation, paid to any non-employee director in a calendar year period will not exceed $1,000,000 in the first calendar year such individual becomes a non-employee director and $750,000 in any other calendar year (with the value of equity compensation based on the grant date fair value thereof).

We will reimburse all reasonable out-of-pocket expenses incurred by directors for their attendance at meetings of our board of directors or any committee thereof.

PROPOSAL NO. 2 – TO APPROVE, BY NON-BINDING ADVISORY VOTE, THE RESOLUTION APPROVING NAMED EXECUTIVE OFFICER COMPENSATION

In accordance with Section 14A of the Exchange Act, we are requesting stockholder approval, on a non-binding advisory basis, of the compensation of our named executive officers during 2022, as described in this proxy statement. This proposal, commonly known as a “say-on-pay” vote, gives our stockholders the opportunity to express their views on the design and effectiveness of our executive compensation program. In accordance with the preference of our stockholders expressed at our “say-on-frequency” vote conducted at our 2022 Annual Meeting of Stockholders, this vote is held on an annual basis. This vote is not intended to address any specific element of compensation, but rather the overall compensation of our named executive officers and the compensation philosophy, policies and practices described in this proxy statement.

As discussed in further under the heading “Compensation Discussion and Analysis” in this proxy statement, the goals of our executive compensation program are to attract, engage, and retain executive officers who share our vision and are deeply connected to our mission. Our overall compensation philosophy is market-based and is designed to enable our executive officers to share with our stockholders in the Company’s long-term success. We strive to incentivize these executive officers to achieve our short-term and long-term business objectives in order to increase stockholder value over the long-term. Our program combines competitive fixed and variable cash compensation as well as time-vested and performance-vested equity award opportunities in the forms and proportions that we believe will motivate our executive officers to increase stockholder value over the long-term. Our compensation program is guided by the following principles:

1. A significant portion of total target compensation should be allocated to incentive-based compensation opportunities;

2. Incentive plan objectives should contribute to increased stockholder value; and

3. A significant portion of total compensation should be in the form of variable compensation.

The Compensation Committee conducts an annual competitive compensation study to guide decisions regarding total and individual compensation components and values. For details on our executive compensation program, we urge you to carefully read the Compensation Discussion and Analysis section of this proxy statement, the 2022 Summary Compensation Table, as well as the other related tables and disclosure.

Accordingly, we are asking our stockholders to approve the following resolution at the Annual Meeting:

RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the named executive officers as disclosed in the Company’s proxy statement for the 2023 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis section, the 2022 Summary Compensation Table and the other related tables and disclosure.

Although this advisory vote is non-binding, our Board and Compensation Committee value the opinions of our stockholders and will consider the outcome of this say-on-pay vote when making future compensation decisions for our executive officers.

The board of directors recommends voting “FOR” Proposal No. 2 to approve, by non-binding advisory vote, the resolution approving named executive officer compensation.

TABLE OF CONTENTS

EXECUTIVE COMPENSATION

This section describes the compensation program for our Named Executive Officers. In particular, this section focuses on our 2022 executive compensation program and related decisions. As a smaller reporting company, we are not required to include a “Compensation Discussion and Analysis” and are permitted to exclude certain executive compensation tables from our disclosure. We have elected to include a Compensation Discussion and Analysis as well as additional tables under Item 402 on a voluntary basis. In addition, we are including Messrs. Hull and Ouimette as additional Named Executive Officers on a voluntary basis solely for purposes of this Proxy Statement.

Compensation Discussion and Analysis

This Compensation Discussion and Analysis provides an overview of our executive compensation program for 2022 and our executive compensation philosophies and objectives.

Our named executive officers consist of our President and Chief Executive Officer, our Chief Financial Officer and our three other most highly compensated executive officers serving in such roles as of December 31, 2022 (collectively, the “Named Executive Officers”). For 2022, our Named Executive Officers were:


Name						Position
Bernard Coulie, M.D., Ph.D.						President, Chief Executive Officer and Director
Keith Cummings, M.D., MBA						Chief Financial Officer
Hans Hull, J.D.						Chief Business Officer
Éric Lefebvre, M.D.						Chief Medical Officer
Mike Ouimette, J.D.						General Counsel & Corporate Secretary

Executive Summary

2022 was a transformative year for the Company as we executed on strategic objectives to advance and expand our portfolio of clinical and preclinical programs. Our key accomplishments during the year included:

•The Company announced positive data from INTEGRIS-IPF, a multinational, randomized, double-blind, placebo-controlled Phase 2a clinical trial of bexotegrast in patients with idiopathic pulmonary fibrosis (IPF). The trial met its primary and secondary endpoints demonstrating that bexotegrast was well tolerated over a 12-week treatment period and displayed a favorable pharmacokinetic profile. The trial’s exploratory efficacy endpoints assessing changes in forced vital capacity (FVC) and Quantitative Lung Fibrosis (QLF) imaging, demonstrated a dose-dependent treatment effect on FVC and QLF versus placebo over 12 weeks in bexotegrast treated patients.

•The Company successfully completed a $230 million public common stock follow-on offering, including full exercise of the underwriters’ option to purchase additional shares.

•The Company announced positive data from its bexotegrast Phase 1b proof-of-mechanism trial where bexotegrast demonstrated clear evidence of on-target biological activity in the lungs of healthy participants.

•The independent Data Safety Monitoring Board recommended the INTEGRIS-IPF Phase 2a trial continue without modification and proceed to evaluate dosing of bexotegrast at 320mg.

•The company reached multiple regulatory milestones including:

•The Company filed an Investigational New Drug application with the U.S. Food and Drug Administration (FDA) for PLN-101095, an oral, small molecule, dual selective inhibitor of integrins αvβ8 and αvβ1.

•The Company received Fast Track designation from the FDA for bexotegrast in IPF and primary sclerosing cholangitis (PSC), and Orphan Designation from the European Medicines Agency for bexotegrast in IPF.

In sum, the Company made progress across all key strategic objectives in 2022, particularly in the lead program for bexotegrast. These accomplishments were reflected by the stock performance of the Company, which returned significant value to stockholders during a year of general poor performance in the pre-commercial biotech industry.

Executive Compensation Philosophy

TABLE OF CONTENTS

The Compensation Committee of the Board (the “Committee”), which is responsible for overseeing the Company’s executive compensation program, believes that the Company’s executive compensation program should reward actions and behaviors that build a foundation for the long-term performance of the Company, while also rewarding achievement of short-term performance goals informed by the Company’s strategy. The goals of our executive compensation program are to attract, engage, and retain executive officers who share our vision and are deeply connected to our mission. Our overall compensation philosophy is market-based and enables our executive officers to share with our stockholders in the Company’s long-term success. We strive to incentivize these executive officers to achieve our short-term and long-term business objectives in order to increase stockholder value over the long-term. Our program combines competitive fixed and variable cash compensation as well as time-vested and performance-vested equity award opportunities in the forms and proportions that we believe will motivate our executive officers to increase stockholder value over the long-term. Our compensation program is guided by the following principles:

1. A significant portion of total target compensation should be allocated to incentive-based compensation opportunities;

2. Incentive plan objectives should contribute to increased stockholder value; and

3. A significant portion of total compensation should be in the form of variable compensation.

Based on our compensation philosophy, our performance-driven annual compensation program consists of three principal pay elements as outlined in the table below:


Pay Elements
	Base Salary	Annual Cash Incentive Awards	Equity Awards
Who Receives	All Named Executive Officers
When Granted	Annually
Form of Delivery	Cash		Stock options
Type of Performance	Short term emphasis		Long-term emphasis
Performance Period	N/A	1 year	4 year time-vesting
How Payout Determined	Committee determination	Based upon market data and established corporate objectives, as well as certain other qualitative factors considered by the Compensation Committee in its discretion.	Based upon stock price appreciation between grant and exercise
2022 Performance Measures	Individual	Clinical, operational and financial performance goals.	N/A

In addition to the principal pay elements described above, in 2022, the Committee approved an equity incentive program outside of the annual equity grant cycle designed to retain talent through key milestones. This program was delivered in the form of performance-based restricted stock units “Incentive Program PSUs”) for executive level employees, including each of the Named Executive Officers. The Incentive Program PSU grants to the Named Executive Officers are described in more detail below.

Key Compensation Policies and Practices

We are committed to having strong governance standards with respect to our executive compensation program, policies and practices. Consistent with this focus, we maintain the following policies and practices that we believe demonstrate our commitment to executive compensation best practices.

TABLE OF CONTENTS


What We Do:
✔			Pay-for-performance. A significant portion of the Named Executive Officers’ compensation is delivered in the form of variable compensation that is connected to our performance or stock price through stock option grants. For 2022, variable compensation comprised approximately 85% of the targeted annual direct compensation for Dr. Coulie and, on average, 70% of the targeted annual direct compensation for the other Named Executive Officers, in each case, excluding the Incentive Program PSUs.
✔			Linkage between quantitative performance measures and operating objectives. Performance measures for annual incentive compensation are linked to operating objectives informed by our business strategy and designed to create long-term stockholder value. In addition, the Incentive Program PSUs vest based on operational performance goals linked to our long-term strategy as well as our relative total shareholder return.
✔			“Double trigger” in the event of a change-in-control. For all of our Named Executive Officers, in the event of a change-in-control, equity awards will accelerate upon a “double trigger” – meaning that both a change in control and qualifying termination of employment must occur for automatic acceleration.
✔			Independent compensation consultant. The Committee retains its own compensation consultant to review the Company’s executive compensation program and practices.
✔			Annual risk assessment. Based on our annual risk assessment, we have concluded that our compensation program does not present a risk that is reasonably likely to have a material adverse effect on the Company.
✔			Annual peer group review. The Committee, with the assistance of its independent compensation consultant, annually reviews the composition of the peer group used to evaluate and assess the Company’s executive compensation program and makes adjustments to the composition of the group as it deems appropriate.
✔			Clawback policy. In 2022, the Committee adopted a compensation clawback policy allowing the Company to recover incentive compensation paid to certain officers (including the Named Executive Officers) in the event of certain financial statement restatements. We will revise this policy as necessary to comply with the final listing rules adopted by Nasdaq with respect to clawback policies.
What We Don't Do:
✘			No change-in-control tax gross-ups.
✘			No material perquisites.
✘			The Company does not maintain excessive severance benefits.
✘			The Company does not allow directors and key executives (including all Named Executive Officers) to hedge or pledge their Company securities.

Compensation of Named Executive Officers

Base Salary

Base salaries are benchmarked against our peer group and intended to provide a level of compensation sufficient to attract and retain an effective management team in the highly competitive biotechnology talent market, when considered in combination with the other components of our executive compensation program. The relative levels of base salary for our Named Executive Officers are designed to reflect each executive officer’s scope of responsibility and accountability with us and are adjusted annually after reviewing market data and individual performance.

The table below sets forth the 2021 and 2022 base salary level for each of our Named Executive Officers:


Named Executive Officer	2021 Annual Base Salary		2022 Annual Base Salary
Bernard Coulie, M.D., Ph.D.	$	556,200	$	586,800
Keith Cummings, M.D., MBA	$	401,700	$	427,200
Hans Hull, J.D.	$	385,700	$	407,000
Éric Lefebvre, M.D.	$	456,000	$	481,100
Mike Ouimette, J.D.	$	362,700	$	398,000

Annual Cash Incentives

During 2022, we provided our senior leadership team with annual cash incentive compensation through our cash bonus plan. Cash incentives hold executives accountable, rewards the executives based on actual business results and helps create a “pay for performance” culture. Our cash bonus plan provides cash incentive award opportunities for the achievement of performance goals

TABLE OF CONTENTS

established by the Committee at the beginning of the fiscal year. Payouts to participants vary based on performance as compared to the target performance goals recommended by the Committee and considered and approved by the Board, with such modifications as the Board determines to be appropriate. The Committee also retains discretion to adjust payouts for any factors it deems appropriate. For 2022, the target bonus opportunities for Dr. Coulie and our other Named Executive Officers under the cash bonus plan were unchanged from 2021, at 55% and 40%, respectively.

The Committee undertakes a rigorous review and analysis to establish performance goals under the cash bonus plan, with the performance goals linked to our operating strategy and key measures of the Company’s success in executing against its strategic operating plan. Consistent with the 2021 program design, for 2022, the Committee established performance goals relating to pre-clinical, clinical, regulatory and program-related metrics (weighted 75%, with the ability to earn an additional 20% of the bonus pool for clinical, program and regulatory metrics) and financial and operational metrics (weighted 25%, with the ability to earn an additional 10% of the bonus pool for the financial and operational metrics). Each goal category had a number of sub-goals, such as program, product and candidate advancement, with a total of twelve sub-goals having a target weighting ranging from 5% to 20%. The goals were designed to be challenging, but achievable with the coordinated, cross-functional focus and effort by the executive team. In determining 2022 performance, the Committee considered the Company’s achievement against the pre-established performance goals, clinical developments relating to certain of the Company’s products as well as the release of positive INTEGRIS-IPF data, strong enrollment performance and strong cash position. Based on the Company’s performance, the Committee approved a 130% bonus pool funding with respect to the 2022 cash bonus plan, with the ability to differentiate payouts on an individual basis based on qualitative assessment of individual performance.

The table below sets forth the target bonus opportunities for each of the Named Executive Officers (each expressed as a percentage of base salary and in dollars), as well as the actual bonus payment amount:


Named Executive Officer	Target Bonus (%)	Target Bonus ($)	Actual Payment ($)
Bernard Coulie, M.D., Ph.D.	55%	$322,740	$440,000
Keith Cummings, M.D., MBA	40%	$170,880	$222,144
Hans Hull, J.D.	40%	$162,800	$211,640
Éric Lefebvre, M.D.	40%	$192,440	$269,416
Mike Ouimette, J.D.	40%	$159,200	$191,040

Equity Incentive Program

To further align the interests of our executive officers with the interests of our stockholders and to further focus our executive officers on our long-term performance, we have historically granted equity compensation in the form of time-vested stock options. The 2022 equity grants were determined based on individual performance, input of the Committee’s independent compensation consultant, and the Committee’s review of the public company market data described below, with the general goal of aligning equity compensation between the 50th and 75th percentiles of the market data. In 2022, the Committee awarded the following stock option grants to the Named Executive Officers, with the stock options generally vesting in 48 monthly installments subject to the recipient’s continued service through each vesting date:


Named Executive Officer									Stock Options (#)
Bernard Coulie, M.D., Ph.D.									440,000
Keith Cummings, M.D., MBA									124,000
Hans Hull, J.D.									112,500
Éric Lefebvre, M.D.									140,000
Mike Ouimette, J.D.									87,000

Incentive Program PSUs

Beginning in early 2022, the Committee undertook a comprehensive review of the Company's compensation programs to evaluate whether they were sufficient to continue to retain and incentivize talent, considering the incredibly competitive market for Company talent at the time as well as guidance from the Committee's independent compensation consultant. As a result of such

TABLE OF CONTENTS

review, in July 2022, the Committee approved the Incentive Program PSUs outside of the annual grant cycle in order to support the retention of key talent through the achievement of key clinical milestones for the Company. Under this incentive program, each of the Named Executive Officers received performance-based restricted stock units, with the grants initially sized based on the 2022 annual grant value and then adjusted based on the criticality of the position and the recipient's compensation relative to the competitive market. The Committee elected to deliver the grant to the Named Executive Officers in the form of performance-based equity in order to incentivize performance with respect to key clinical objectives and other actions that would support the creation of stockholder value.

Under the terms of the Incentive Program PSUs, vesting is tied to clinical and relative total shareholder return (“TSR”) goals, with performance measured through the second quarter of 2024. The vesting of 50% of the Incentive Program PSUs is tied to the achievement of three operational performance goals relating to IPF. The operational goals were designed to be challenging but achievable with strong execution of the Company's clinical operating plan. In December 2022, the first operational goal relating to the progression of clinical trial in IPF was achieved and 50% of the operational goal PSUs vested. Vesting of the remaining 50% of the Incentive Program PSUs is tied to the Company's TSR relative to the Nasdaq Biotechnology Index, as follows:

Performance Level

*The vesting percentage will be determined using straight-line interpolation between performance levels. In the event the Company’s absolute total shareholder return is negative during the performance period, the Compensation Committee retained discretion to reduce the vesting percentage to no greater than target, as determined by the Compensation Committee to be appropriate.

Under the Incentive Program PSUs, the Named Executive Officers received the following target PSUs:


Named Executive Officer									Target PSUs (#)
Bernard Coulie, M.D., Ph.D.									275,000
Keith Cummings, M.D., MBA									77,500
Hans Hull, J.D.									70,313
Éric Lefebvre, M.D.									87,500
Mike Ouimette, J.D.									54,375

Other Elements of Our 2022 Executive Compensation Program

Severance Arrangements

The Company generally executes an offer of employment before an executive joins the Company. This offer describes the basic terms of the executive’s employment, including his or her start date, starting salary, annual incentive target, initial equity grants and, in some cases, severance entitlements. In addition, we maintain an Executive Severance Plan (the “Severance Plan”), in which our Named Executive Officers, and certain other executives, participate. The benefits provided in the Severance Plan replaced any severance for which our Named Executive Officers may be eligible under their existing offer letters or other agreements or arrangements, except to the extent such offer letters or other agreements, or arrangements provide for greater benefits.

The Severance Plan helps accomplish the Company’s compensation philosophy of attracting and retaining exemplary talent as it was designed to be aligned with competitive market practices. The Severance Plan reduces the need to negotiate individual severance arrangements with departing executives and protects our executives from termination for circumstances not of their doing. The Committee also believes the Severance Plan promotes management independence and helps retain, stabilize, and focus the executive officers in the event of a change-in-control.

TABLE OF CONTENTS

Please see the “Executive Compensation—Potential Payments Upon Termination or Change-in-Control” section of this Proxy Statement for further information regarding the Severance Plan, including the treatment of awards upon qualifying termination events or a change-in-control.

Other Benefits

Our Named Executive Officers participate in our corporate-wide benefit programs. Our Named Executive Officers are offered benefits that generally are commensurate with the benefits provided to all of our full-time employees, which includes participation in our qualified defined contribution plan. We do not provide perquisites, other than an annual home travel reimbursement, including associated tax reimbursement to Dr. Coulie which was provided as part of his initial employment agreement and relocation in 2015 (amounts reflected in the “All Other Compensation” column in the 2022 Summary Compensation Table below).

Clawback Policy

The Company maintains a clawback policy, which applies to individuals designated by the Board as executive officers for purposes of Section 16 of the Exchange Act as well as other key employees designated by the Committee. Our policy generally provides that, in the event that (i) an incentive compensation payment or award (or the vesting of such award) was based upon the achievement of financial results that were subsequently the subject of a restatement to correct an accounting error due to material noncompliance with any financial reporting requirement under the federal securities laws and (ii) a lower incentive compensation payment or award would have been made to such officer (or lesser or no vesting would have occurred with respect to such award) based upon the restated financial results, then we will recover the full or partial portion of cash or equity-based incentive compensation received by such officer during the three fiscal years preceding the date on which we were required to prepare the restatement. Our policy is separate from and in addition to requirements of Section 304 of the Sarbanes-Oxley Act of 2002 that are applicable to our Chief Executive Officer and Chief Financial Officer. The Company continues to monitor this policy to ensure that it is consistent with applicable laws and will review and modify the policy as necessary to reflect the final Nasdaq listing rules adopted to implement the compensation recovery requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”).

How We Make Executive Compensation Decisions

Role of the Board, Compensation Committee and our Executive Officers

The Committee determines the compensation of our Chief Executive Officer and each of our other executive officers and reports its decisions to the Board. In setting the compensation of our Chief Executive Officer, the Committee assesses and takes into account the Chief Executive Officer’s individual performance. In setting the compensation of our other executive officers, the Committee takes into account the Chief Executive Officer’s review of each executive officer’s performance and his recommendations with respect to their compensation. The Committee’s responsibilities regarding executive compensation are further described in the “Corporate Governance” section of this proxy statement.

Guidance from Independent Compensation Consultant

Aon is engaged at the sole discretion of the Committee to provide executive compensation consulting services. With respect to 2022, Aon provided services related to the review of 2022 compensation adjustments including a review of peer group compensation data, awards under our equity incentive program, the award levels and design of the Incentive Program PSUs, the setting of performance goals in our annual incentive plan, an analysis of the relationship between the Company’s pay and performance relative to peers, trends and tax and regulatory developments with respect to executive compensation, our compensation peer group, our non-employee director compensation program, and assistance with this Compensation Discussion and Analysis. Aon is retained by and reports to the Committee and, at the request of the Committee, participates in Committee meetings. Aon did not provide any services to the Company with respect to 2022 other than those provided to the Committee. The Committee reviewed the independence of Aon under Nasdaq and SEC rules and concluded that the work of Aon has not raised any conflict of interest.

Comparison to Relevant Peer Group

TABLE OF CONTENTS

To obtain a broad view of competitive practices among industry peers and competitors for executive talent, the Committee reviews market data for peer group companies. The Committee believes that our executive compensation peer group should reflect the markets in which the Company competes for business, executive talent and capital and selects companies based on the following peer selection criteria:

•Industry: Public U.S. Pre-Commercial Biopharma Organizations

•Company Profile: Predominantly in Phase II and Phase III Clinical Trials

•Market Capitalization: $250 million to $2.5-billion

•Number of employees: Fewer than 150

•Companies located in biotech talent hubs

In selecting companies for our peer group, the Committee considers recommendations from Aon. The Committee approved the peer group of companies set forth below to evaluate 2022 executive compensation decisions. This was the same peer group that was used to evaluate 2021 compensation decisions except for (i) the removal of Chiasma, Eidos Therapeutics and Principia Biopharma due to acquisition; (ii) Abeona Therapeutics, Adverum Biotechnologies, Calithera Biosciences, Corbus Pharmaceuticals, Odonate Therapeutics and Unity Biotechnology due to market capitalization considerations and (ii) the addition of 89bio, Aligos Therapeutics, Annexon, KalVista Pharmaceuticals, Poseida Therapeutics, Praxis Precision Medicines and Tarsus Pharmaceuticals due to market capitalization, company profile and geographic considerations.

1. 89bio

2. Aeglea BioTherapeutics

3. Aligos Therapeutics

4. Annexon

5. AVROBIO

6. Cortexyme

7. Crinetics Pharmaceuticals

8. CytomX Therapeutics

9. Dicerna Pharmaceuticals

10. Eiger BioPharmaceuticals

11. KalVista Pharmaceuticals

12. Kezar Life Sciences

13. Morphic

14. Poseida Therapeutics

15. Praxis Precision Medicines

16. Protagonist Therapeutics

17. Replimune Group

18. Rocket Pharmaceuticals

19. Scholar Rock

20. Tarsus Pharmaceuticals

For 2022, the Committee considered market pay practices to assess the overall competitiveness and reasonableness of the Company’s executive compensation program. While the Committee considers relevant market pay practices when setting executive compensation, it does not believe it is appropriate to establish compensation levels based only on market practices. The Committee believes that compensation decisions are complex and require a deliberate review of Company and individual performance and peer compensation levels.

(1) The amounts shown represent performance-vested stock units granted under the 2020 Stock Option and Incentive Plan (the “2020 Plan”) to each of the Company’s Named Executive Officers. The shares subject to these performance-vested stock units vest based on the achievement of various operational and shareholder return goals and the Named Executive Officer’s continuous service on the applicable vesting date. The amounts included in the Stock Awards column for the performance-vested stock units are calculated based on the probable satisfaction of the performance conditions for such awards as of the date of grant. Assuming the highest level of performance is achieved for the 2022 performance-vested stock units with vesting tied to the operational goals, the maximum value of the operational performance-vested stock units would be as follows: Dr. Coulie, $4,831,750; Dr. Cummings, $1,361,675; Mr. Hull, $1,235,382; Dr. Lefebvre, $1,537,375; and Mr. Ouimette, $955,351. Under FASB ASC Topic 718, the vesting condition related to the performance-vested stock units with vesting tied to total shareholder return is considered a market condition and not a performance condition. Accordingly, there is no grant date fair value below or in excess of the amount reflected in the table above for the Named Executive Officers that could be calculated and disclosed based on achievement of the underlying market-based vesting condition. Please see “Compensation Discussion & Analysis - Compensation of Named Executive Officers – Performance-Vested Restricted Stock Units” for further information regarding these awards.

(2) Reflects the aggregate grant date fair value of the awards, computed in accordance with the FASB ASC Topic 718. The assumptions used in calculating the grant date fair value of the 2022 stock option awards and performance-vested stock unit awards reported in this column are set forth in note 10 to our consolidated financial statements included in our annual report on Form 10-K for the year ended December 31, 2022. The amounts reported in this column reflect the accounting cost for these stock option and performance-vested stock unit awards and do not correspond to the actual economic value that may be received by our Named Executive Officers upon the exercise of the stock option awards, the vesting of performance-vested stock units, or any sale of the underlying shares of common stock.

(3) For 2022, represents cash amounts earned by our Named Executive Officers under our annual cash incentive program, based on the Company’s achievement of certain corporate performance goals and the Named executive Officers’ individual performance.

(4) The amount reported for each Named Executive Officer represents the matching contributions made by the Company under its 401(k) plan during the year, and in the case of Dr. Coulie, the amount reported also includes personal travel reimbursements paid by the Company pursuant to his employment agreement.

Employment, Severance and Change of Control Agreements

Executive Severance Plan

In 2020, our board of directors adopted an Executive Severance Plan (the “Severance Plan”), in which our Named Executive Officers, and certain other executives, participate. 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 of 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 the Company and continued compliance with all applicable restrictive covenants, (i) 12 months of “base salary” (i.e., the higher of the annual base salary in effect immediately prior to the date of termination or the annual base salary in effect for the year immediately prior to the year in which the date of termination occurs) for our Chief Executive Officer and nine months of base salary for the other Named Executive Officers, (ii) an amount equal to the Named Executive Officer’s target annual bonus in effect immediately prior to the date of termination, pro-rated for the number of days employed during the year of termination, and (iii) an amount equal to the monthly employer contribution, based on the premiums as of the date of termination, that we would have made to provide health insurance for the Named Executive Officer if he had remained employed by us for up to 12 months for our Chief Executive Officer and nine months for our other Named Executive Officers. The payments under (i), (ii) and (iii) will be paid in substantially equal installments in accordance with our payroll practice over 12 months for our Chief Executive Officer and nine months for our other 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 the 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 (or immediately prior to the change in control, if higher) 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 (or immediately prior to the change in control, if higher) for our other Named Executive Officers (II) a lump sum amount equal to the monthly employer contribution, based on the premiums as of the date of termination, that we would have made to provide health insurance for the participant if the applicable Named Executive Officer had remained employed by us for 18 months for our Chief Executive Officer and 12 months for our other Named Executive Officers and (III) for all outstanding and unvested equity awards of the Company that are subject to time-based 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 except, that in the case of the 2022 performance-vested stock unit with vesting tied to total shareholder return, in the event of a change in control, vesting will be deemed achieved at the greater of (i) target and (ii) actual performance through the date of the change in control.

TABLE OF CONTENTS

The payments and benefits provided under the Severance Plan may subject an eligible participant, including the Named Executive Officers, to an excise tax under Section 4999 of the Code. If the payment 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.

2022 Potential Payments Upon Change in Control and Termination Table

(4) The payments and benefits provided under the Severance Plan may subject an eligible participant, including the Named Executive Officers, to an excise tax under Section 4999 of the Code.

The amounts reported in this table do not reflect the application of any reduction in payments or benefits.

Compensation Risk Assessment

We believe that although a portion of the compensation provided to our executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. Our compensation programs are designed to encourage our executive officers and other employees to remain focused on both short-term and long-term strategic goals, in particular in connection with our pay-for-performance compensation philosophy. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

Pursuant to Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, the Pay Versus Performance Table (set forth below) is required to include “Compensation Actually Paid,” as calculated per SEC disclosure rules, to the Company’s principal executive officer (“PEO”) and the Company’s non-PEO Named Executive Officers, as noted below. “Compensation Actually Paid” represents a new required calculation of compensation that differs significantly from the Summary Compensation Table calculation of compensation, the Named Executive Officer’s realized or earned compensation, as well as from the way in which the Compensation Committee views annual compensation decisions, as discussed in the Compensation Discussion and Analysis. The amounts in the table below are calculated in accordance with SEC rules and do not represent amounts actually earned or realized by our Named Executive Officers, including with respect to our equity awards which remain subject to forfeiture if the vesting conditions are not satisfied. As permitted under the rules applicable to Smaller Reporting Companies, we are including two years of data and are not including a peer group total shareholder return or company-selected measure, as contemplated under Item 402(v) of Regulation S-K.

Relationship Between Pay and Performance

We believe the “Compensation Actually Paid” in each of the years reported above and over the two-year cumulative period are reflective of the Compensation Committee’s emphasis on “pay-for-performance” as the “Compensation Actually Paid” fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against our performance goals under our annual cash incentive program. As is the case with many pre-commercial companies in the biotechnology industry, the Company’s incentive objectives are predominantly tied to the Company’s strategies and operational goals rather than financial goals. Accordingly, the Company’s compensation program is not meaningfully influenced by financial metrics, such as net loss.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Except for the compensation arrangements, including employment, termination of employment and change in control arrangements, with our directors and executive officers, including those discussed in the sections entitled “Management,” “Executive Compensation” and “Director Compensation,” there have been no transactions since January 1, 2022 in which:

•we have been or are to be a participant;

•the amounts involved exceeded or will exceed $120,000; and

•any of our directors, executive officers or holders of more than 5% of our capital stock, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest.

Indemnification Agreements

We have entered into new agreements to indemnify our directors, executive officers, and other officers as determined from time to time by our board of directors or our Compensation Committee. These agreements and our amended and restated bylaws, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts reasonably incurred by such person in certain actions or proceeding, including any action, on account of any services undertaken by such person on behalf of our company or that person’s status as a member of our board of directors to the maximum extent allowed under Delaware law. We are also required by these agreements to indemnify these individuals for certain expenses (including attorney’s fees) in certain action or proceeding by or in our right.

Policies for Approval of Related Party Transactions

Our board of directors has adopted and approved a written Related Person Transaction Policy. The policy sets forth our procedures for the identification, review, consideration and approval or ratification of related person transactions. For purposes of our policy only, a related person transaction is any transaction in which we are a participant and a related person has a direct or indirect material interest. Transactions involving compensation for services provided to us as an employee or director are not covered by this policy. A related person is any executive officer, director, director nominee, or beneficial owner of more than 5% of any class of our voting securities, including any of their immediate family members.

TABLE OF CONTENTS

Under the policy, we will provide our Audit Committee with all material information regarding such related person transaction. Our Audit Committee will review the material facts of all related person transactions, taking into account, among other factors that it deems appropriate, whether the related person transaction is on terms no

less favorable to us than terms generally available in a transaction with an unaffiliated third-party under the same or similar circumstances and the extent of the related person’s interest in the transaction. To facilitate identification of related person transactions, we will compile a list of all related persons and related person affiliates, and updated the list at least annually, based on questionnaires completed by our directors and officers. Each of our directors, officers and director nominees shall also be responsible for promptly notifying us of any change in the identity of relevant related party affiliates.

In addition, under our Code of Conduct, our employees and directors have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest.

In considering related person transactions, our Audit Committee, or other independent body of our board of directors, will take into account the relevant available facts and circumstances including, but not limited to:

•the size of the transaction and the amount payable to a related person;

•the nature of the interest of the related person in the transaction;

•whether the transaction may involve a conflict of interest;

•whether the transaction was undertaken in the ordinary course of business of the Company;

•whether the transaction involves the provision of goods or services to the Company that are available from unaffiliated third parties and, if so, whether the transaction is on terms and made under circumstances that are at least as favorable to the Company as would be available in comparable transactions with or involving unaffiliated third parties; and

•any other information regarding the related person transaction or related person that would be material to investors in light of the circumstances of the transaction.

The policy requires that, in determining whether to approve, ratify, or reject a related person transaction, our Audit Committee, or other independent body of our board of directors, must consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, our best interests and those of our stockholders, as our Audit Committee, or other independent body of our board of directors, determines in the good faith exercise of its discretion. Some of the indemnification agreements described above were entered into prior to the adoption of the written policy, but all were approved by our board of directors considering similar factors to those described above.

PRINCIPAL STOCKHOLDERS

The following table presents information concerning the beneficial ownership of the shares of our common stock as of April 14, 2023 by:

•each person we know to be the beneficial owner of 5% or more of our outstanding shares of our capital stock;

•each of our directors and director nominees;

•each of our named executive officers; and

•all of our current executive officers and directors as a group.

We have determined beneficial ownership in accordance with SEC rules. The information does not necessarily indicate beneficial ownership for any other purpose. Under these rules, a person is deemed to be a beneficial owner of our common stock if that person has a right to acquire ownership within 60 days by the exercise of options. A person is also deemed to be a beneficial owner of our common stock if that person has or shares voting power, which includes the power to vote or direct the voting of our common stock, or investment power, which includes the power to dispose of or to direct the disposition of such capital stock. Except in cases where community property laws apply or as indicated in the footnotes to this table, we believe that each stockholder identified in the table possesses sole voting and investment power over all shares of common stock shown as beneficially owned by the stockholder.

Percentage of beneficial ownership in the table below is based on 59,156,430 shares of common stock deemed to be outstanding as of April 14, 2023. Shares of common stock subject to options that are currently exercisable or exercisable within 60 days of April 14, 2023 are considered outstanding and beneficially owned by the person holding the options for the purpose of computing the percentage ownership of that person but are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated below, the address of each individual listed below is c/o Pliant Therapeutics, Inc., 260 Littlefield Avenue, South San Francisco, California 94080.

Under U.S. securities laws, directors, certain officers and persons holding more than 10% of our common stock must report their initial ownership of our common stock and any changes in their ownership to the SEC. To our knowledge, based solely on our review of copies of the reports filed with the SEC and the written representations of our directors and executive officers that no other reports were required to be filed during fiscal year 2022, we believe that for fiscal year 2022, all required reports were filed on a timely basis with the exception of one Form 4 report reporting the annual grant of compensatory stock options for each of Drs. Coulie, Lefebvre and Cummings and Messrs. Hull and Ouimette, which were filed three days late due to clerical error.

PROPOSAL NO. 3 – RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS PLIANT’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023

Pliant’s stockholders are being asked to ratify the appointment by the Audit Committee of the board of directors of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023. Deloitte & Touche LLP has served as our independent registered public accounting firm since 2018.

The Audit Committee is solely responsible for selecting our independent registered public accounting firm for the fiscal year ending December 31, 2023. Stockholder approval is not required to appoint Deloitte & Touche LLP as our independent registered public accounting firm. However, the board of directors believes that submitting the appointment of Deloitte & Touche LLP to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the Audit Committee will reconsider whether to retain Deloitte & Touche LLP. If the selection of Deloitte & Touche LLP is ratified, the Audit Committee, at its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of the Company and its stockholders.

A representative of Deloitte & Touche LLP is expected to be present at the virtual Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

The following table sets forth all fees paid or accrued by us for professional audit services and other services rendered by Deloitte & Touche LLP during the years ended December 31, 2022 and December 31, 2021.

All other fees(3)	1,895		1,895
Total fees	$	1,398,580	$	1,354,666

(1) Audit fees consist of fees for professional services provided by Deloitte & Touche LLP for the audit of our annual financial statements, the review of interim consolidated financial statements and consultations on accounting matters directly related to the audit, and comfort letters, consents, and assistance with and review of documents filed with the SEC.

(2) Tax fees consist of fees for performing a Section 382 study.

(3) All other fees consist of fees paid for a subscription to Deloitte & Touche LLP’s accounting research tool.

Audit Committee Pre-approval Policy and Procedures

Our Audit Committee has adopted policies and procedures relating to the approval of all audit and non-audit services that are to be performed by our independent registered public accounting firm. This policy provides that we will not engage our independent registered public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by our Audit Committee, or the engagement is entered into pursuant to the pre-approval procedure described below.

From time to time, our Audit Committee may pre-approve specified types of services that are expected to be provided to us by our independent registered public accounting firm during the next 12 months. Any such pre-approval details the particular service or type of services to be provided and is also generally subject to a maximum dollar amount.

During our 2022 and 2021 fiscal years, no services were provided to us by Deloitte & Touche LLP other than in accordance with the pre-approval policies and procedures described above.

The board of directors and the Audit Committee recommend voting “FOR” Proposal No. 3 to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee has reviewed and discussed the audited financial statements of the Company with management of the Company. In addition, the Audit Committee has discussed with Deloitte & Touche LLP (“Deloitte”) the matters required to be discussed by Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee has received from Deloitte the written

TABLE OF CONTENTS

disclosures and the letter required by applicable requirements of the PCAOB regarding Deloitte’s communications with the Audit Committee concerning independence and has discussed with Deloitte the independence of Deloitte from the Company and its management. Based on the foregoing, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K filed with the SEC for the fiscal year ended December 31, 2022.

Respectfully submitted by the members of the Audit Committee of the board of directors:

Smital Shah, MBA (chairperson)

HOUSEHOLDING

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our documents, including the annual report to stockholders and proxy statement, may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you upon written or oral request to Pliant Therapeutics, Inc., 260 Littlefield Avenue, South San Francisco, CA 94080, Attention: Corporate Secretary, telephone: (650) 481-6770. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.

STOCKHOLDER PROPOSALS

A stockholder who would like to have a proposal considered for inclusion in our 2024 proxy statement must submit the proposal in accordance with the procedures outlined in Rule 14a-8 of the Exchange Act so that it is received by us no later than December 28, 2023. SEC rules set standards for eligibility and specify the types of stockholder proposals that may be excluded from a proxy statement. Stockholder proposals should be addressed to Pliant Therapeutics, Inc., 260 Littlefield Avenue, South San Francisco, CA 94080, Attention: Corporate Secretary.

If a stockholder wishes to propose a nomination of persons for election to our board of directors or present a proposal at an annual meeting but does not wish to have the proposal considered for inclusion in our proxy statement and proxy card, our bylaws establish an advance notice procedure for such nominations and proposals.
