Dear Fellow Stockholders:
You are cordially invited to attend the 2024 annual meeting of stockholders (the “Annual Meeting”) of Krystal Biotech, Inc., which will be held virtually at www.virtualshareholdermeeting.com/KRYS2024, on May 17, 2024, at 4:00 p.m. Eastern Time.
The matters expected to be acted upon at the Annual Meeting are described in detail in the accompanying Notice of Annual Meeting of Stockholders and Proxy Statement.
In accordance with U.S. Securities and Exchange Commission “notice and access” rules, we are using the Internet as our primary means of furnishing proxy materials to our stockholders. Because we are using the Internet, most stockholders will not receive paper copies of our proxy materials. We will instead send our stockholders a notice with instructions for accessing the proxy materials and voting via the Internet. This notice also provides information on how our stockholders may obtain paper copies of our proxy materials if they so choose. We believe the use of the Internet makes the proxy distribution process more efficient and less costly and helps in conserving natural resources.
The Proxy Statement, the accompanying form of proxy card, the Notice of Annual Meeting of Stockholders and our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, are available at www.proxyvote.com and may also be accessed through our website at www.krystalbio.com under the “SEC Filings” section of the “Investors” page. If you would like to receive a paper or e-mail copy of these documents, you must request one. There is no charge to you for requesting a copy.
Your vote is important. Please cast your vote as soon as possible over the Internet, by telephone, or by completing and returning the proxy card to ensure that your shares are represented. Your vote by proxy will ensure your representation at the Annual Meeting regardless of whether or not you attend the Annual Meeting. Casting your vote by proxy does not deprive you of your right to attend the Annual Meeting and vote your shares.
On behalf of our Board of Directors and our employees, we thank you for your continued interest in and support of our company. We look forward to your attendance at the Annual Meeting on May 17, 2024.
Sincerely,
/s/ Krish S. Krishnan
Krish S. Krishnan
Chairman and Chief Executive Officer

PROXY STATEMENT
ABOUT THE MEETING
Why am I receiving this Proxy Statement?
This Proxy Statement contains information related to the solicitation of proxies for use at our Annual Meeting to be held virtually at www.virtualshareholdermeeting.com/KRYS2024, on May 17, 2024, at 4:00 p.m. Eastern Time, for the purposes stated in the accompanying Notice of Annual Meeting of Stockholders. This solicitation is made by Krystal Biotech, Inc. on behalf of our Board of Directors (also referred to as the “Board” in this Proxy Statement). “We,” “our,” “us,” “Krystal,” and the “Company” refer to Krystal Biotech, Inc.
We have elected to provide access to our proxy materials over the Internet. Accordingly, we are sending to our stockholders of record as of the close of business on March 25, 2024, the Record Date for the Annual Meeting, the Notice relating to the Annual Meeting. All stockholders of record will have the ability to access the proxy materials on the website referred to in the Notice or to request to receive a printed set of the proxy materials. Instructions on how to request a printed copy by mail or electronically may be found on the Notice and on the website referred to in the Notice, including an option to request paper copies on an ongoing basis. On or about April 4, 2024, we intend to make this Proxy Statement and accompanying form of proxy card available on the Internet and to mail the Notice to all stockholders entitled to notice of and to vote at the Annual Meeting. We intend to mail this Proxy Statement, together with a proxy card, to those stockholders entitled to notice of and to vote at the Annual Meeting who have properly requested paper copies of such materials, within three business days of such request.
The Notice, this Proxy Statement, accompanying form of proxy card and our Annual Report to Stockholders on Form 10-K for the fiscal year ended December 31, 2023, are available at www.proxyvote.com. You are encouraged to access and review all the important information contained in the proxy materials before voting.
What is a proxy?
A proxy is your legal designation of another person to vote the stock you own. The person you designate is your “proxy,” and you give the proxy authority to vote your shares by submitting the enclosed proxy card or voting by telephone or the Internet. We have designated each of Krish Krishnan, our Chairman and Chief Executive Officer, and John Thomas, our General Counsel and Corporate Secretary, to serve as proxies for the Annual Meeting.
What am I being asked to vote on?
You are being asked to vote on the following proposals:
•    Proposal 1 (Election of Class I Directors): The election of the three Class I director nominees named in this Proxy Statement, each for a three-year term expiring at the 2027 annual meeting of stockholders (the “2027 Annual Meeting”);
•    Proposal 2 (Ratification of KPMG LLP): The ratification of KPMG LLP (“KPMG”) as our independent registered public accounting firm for our fiscal year ending December 31, 2024;
•    Proposal 3 (Compensation of Our Named Executive Officers): The approval of the compensation of our named executive officers on a non-binding, advisory basis; and
•    To transact any other business that may properly come before the Annual Meeting or any adjournment(s) or postponements of the Annual Meeting.

What are the Board’s voting recommendations?
The Board recommends that you vote as follows:
•    Proposal 1 (Election of Class I Directors): “FOR” each of the Board nominees for election as Class I directors;
•    Proposal 2 (Ratification of KPMG): “FOR” the ratification of KPMG as our independent registered public accounting firm for our fiscal year ending December 31, 2024; and
•    Proposal 3 (Compensation of Our Named Executive Officers): “FOR” the approval, on a non-binding, advisory basis, of the compensation of our named executive officers.
Who is entitled to vote at the Annual Meeting?
Only holders of record of our common stock, par value $0.00001 per share (our “Common Stock”), at the close of business on March 25, 2024, which is the Record Date, are entitled to receive notice of the Annual Meeting and to vote at the Annual Meeting. Our Common Stock constitutes the only class of securities entitled to vote at the Annual Meeting.
What are the voting rights of stockholders?
Each share of our Common Stock outstanding on the Record Date entitles its holder to cast one vote on each matter to be voted on at the Annual Meeting.
Who can attend the Annual Meeting?
All holders of our Common Stock as of the Record Date, or their duly appointed proxies, are authorized to attend the Annual Meeting.
What is the difference between holding shares as a stockholder of record and as a beneficial owner?
Many stockholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially.
•    Stockholder of record. If your shares are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered the stockholder of record of those shares and the Notice is being sent directly to you by us.
•    Beneficial owner of shares held in street name. If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the “beneficial owner” of shares held in “street name,” and the Notice is being forwarded to you by your broker, bank or other nominee, which is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares and are also invited to attend the Annual Meeting. However, because you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you have a legal proxy from the organization that holds your shares.
What will constitute a quorum at the Annual Meeting?
The presence at the Annual Meeting, virtually or by proxy, of the holders of a majority of our Common Stock outstanding on the Record Date will constitute a quorum, permitting our stockholders to conduct business at the Annual Meeting. We will include abstentions and broker non-votes in the calculation of the number of shares considered to be present at the Annual Meeting for purposes of determining the presence of a quorum at the Annual Meeting. As of the Record Date, there were 28,514,547 shares of our Common Stock outstanding.
If a quorum is not present to transact business at the Annual Meeting or if we do not receive sufficient votes in favor of the proposals by the date of the Annual Meeting, the persons named as proxies may propose one or more
2


adjournments of the Annual Meeting to permit solicitation of additional proxies. The chairperson of the Annual Meeting shall have the power to adjourn the Annual Meeting.
What are broker non-votes?

If, on the Record Date, your shares of Common Stock are held through a bank, broker or other nominee, then you are the beneficial owner of shares held in “street name,” and you will need to submit voting instructions to the institution that holds your shares. If you do not provide voting instructions to your bank, broker or other nominee, the institution that holds your shares can only vote your shares with respect to “routine” proposals, under applicable securities exchange rules.

If you are a beneficial owner and do not provide your bank, broker or other nominee with voting instructions, your shares may constitute “broker non-votes.” Generally, broker non-votes occur on a matter when a bank, broker or other nominee is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given.
Proposal 2 is the only routine proposal to be brought at the Annual Meeting. Thus, if you are a beneficial owner and your shares are held in the name of a bank, broker or other nominee, the bank, broker or other nominee is permitted to vote your shares on the ratification of the appointment of KPMG as our independent registered public accounting firm for our fiscal year ending December 31, 2024, even if the bank, broker or other nominee does not receive voting instructions from you.
Proposals 1 and 3 are non-routine proposals. Thus, if you are a beneficial owner and do not give your bank, broker or other nominee voting instructions, your bank, broker or other nominee will not be able to vote on those proposals.
How many votes are needed for the proposals to pass?
The proposals to be voted on at the Annual Meeting have the following voting requirements:
•    Proposal 1 (Election of Class I Directors): Directors are elected by plurality vote. There is no cumulative voting in the election of directors. Therefore, the three director nominees receiving the highest number of “FOR” votes will be elected. For purposes of the election of directors, abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote, although they will be considered present for the purpose of determining the presence of a quorum.
•    Proposal 2 (Ratification of KPMG): The affirmative vote of a majority of the votes cast once a quorum has been established is required to ratify the appointment of KPMG as our independent registered public accounting firm for our fiscal year ending December 31, 2024. For purposes of the vote on the ratification of KPMG as our independent registered public accounting firm, abstentions will not be counted as votes cast and will have no effect on the result of the vote, although they will be considered present for the purpose of determining the presence of a quorum.
•    Proposal 3 (Compensation of Our Named Executive Officers): The approval of the compensation of our named executive officers, on a non-binding, advisory basis, requires the affirmative vote of a majority of the votes cast. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote, although they will be considered present for the purpose of determining the presence of a quorum. Because your vote is advisory, it will not be binding on the Board or the compensation committee of the Board (the “Compensation Committee”), but the Board and Compensation Committee will review the voting results and take them into consideration when making future decisions about executive compensation.
Will any other matters be voted on?
As of the date of this Proxy Statement, we are not aware of any matters that will come before the Annual Meeting other than those disclosed in this Proxy Statement. If any other matters are properly brought before the Annual Meeting, the persons named in the accompanying proxy card will vote the shares represented by the proxies on
3


the other matters in the manner recommended by the Board, or, if no such recommendation is given, in the discretion of the proxy holders.
How do I vote?
If you are a registered stockholder as of the Record Date, you may submit your proxy by U.S. mail, Internet or telephone by following the instructions in the Notice. You may also vote at the Annual Meeting if you attend virtually. The deadline for submitting your vote by Internet or telephone is 11:59 p.m. Eastern Time on the day before the date of the Annual Meeting. If you requested a paper copy of the proxy materials, you also may submit your completed proxy card by mail by following the instructions included with your proxy card. If the proxy card is properly signed and returned, and not subsequently revoked, the designated proxy holders named in the proxy card will vote according to your instructions. If you submit a signed proxy card without indicating your voting instructions, the designated proxy holders will vote your shares in accordance with the Board’s recommendations, as follows: (1) “FOR” the election of all nominees for the Board named in this Proxy Statement; (2) “FOR” the ratification of the appointment of KPMG as our independent registered public accounting firm for the fiscal year ending December 31, 2024; (3) “FOR” the approval, on a non-binding, advisory basis, of the compensation of our named executive officers; and (4) as recommended by the Board with regard to any other matters that may properly come before the Annual Meeting. If no such recommendation is given by the Board, in the designated proxy holders’own discretion.
If you are a street name or beneficial stockholder because your shares are held in a brokerage account or by a bank or other nominee, your broker or nominee firm will provide you with the Notice. Follow the instructions on the Notice to access our proxy materials and vote by Internet or to request a paper or email copy of our proxy materials. If you receive these materials in paper form, the materials include a voting instruction card so that you can instruct your broker or nominee how to vote your shares.
How do I access the Annual Meeting Online?
The Annual Meeting will be conducted virtually via a webcast available at www.virtualshareholdermeeting.com/KRYS2024. You are entitled to participate in the Annual meeting via the webcast if you were a stockholder as of the close of business on the Record Date or hold a valid proxy for the meeting. To be admitted to the annual meeting at www.virtualshareholdermeeting.com/KRYS2024, you must enter the 16-digit control number found next to the label “Control Number” for postal mail recipients or within the body of the email sending you the Proxy Statement. If you do not have your 16-digit control number, you will be able to login as a guest but will not be able to vote your shares or submit questions during the meeting. Support staff will be available should you experience any technical difficulties in accessing the virtual meeting. Instructions for requesting technical assistance will be available at www.virtualshareholdermeeting.com/KRYS2024.
If I plan to attend the Annual Meeting, should I still vote by proxy?
Yes. Voting in advance does not affect your right to attend the Annual Meeting. If you vote via the Internet, by telephone, or by completing and returning the proxy card or voting instruction card and attend the Annual Meeting, you do not need to vote again at the Annual Meeting unless you want to change your vote. If you are a record holder, you will be able to vote at the Annual Meeting using your 16-digit control number. Any votes cast with respect to a particular control number at the Annual Meeting will cancel any prior votes associated with that control number.
May I revoke my vote after I return my proxy card?
Yes.

PROPOSALS TO BE VOTED ON
PROPOSAL 1: ELECTION OF CLASS I DIRECTORS
Our Board of Directors is divided into three classes of directors, each serving staggered three-year terms. The Board is currently comprised of nine directors, three of whom have terms expiring at the Annual Meeting. The nominees, each of whom is currently serving as a Class I director, have been recommended by the Board for re-election to serve as directors for three-year terms until the 2027 Annual Meeting and until their successors are duly elected and qualified.
The Board knows of no reason why the nominees would be unable to serve as a director. If the nominees are unavailable for election or service, the Board may designate a substitute nominee and the persons designated as proxy holders on the proxy card will vote for the substitute nominee recommended by the Board. Under these circumstances, the Board may also, as permitted by our bylaws, decrease the size of the Board.

PROPOSAL 3: NON-BINDING, ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION
Our Board is providing our stockholders with an opportunity to cast a non-binding, advisory vote to approve the compensation of our named executive officers.
Section 14A of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”) enables our stockholders to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the rules of the Securities and Exchange Commission (“SEC”). As described below under “Compensation Discussion and Analysis,” we have developed a compensation program that is designed to motivate employees to achieve short-term and long-term results that are in the best interests of our Company and stockholders. We believe our compensation policy strikes an appropriate balance between the implementation of responsible, measured compensation practices and the effective provision of incentives for our named executive officers to exert their best efforts for our success.
We are asking for stockholder approval, on a non-binding, advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement, which includes the disclosures under the Compensation Discussion and Analysis section below, including the compensation tables and the narrative discussion following the compensation tables in this Proxy Statement. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the policies and practices described in this Proxy Statement. Accordingly, our Board is asking our stockholders to cast a non-binding advisory vote “FOR” the following resolution at the Annual Meeting:
“BE IT RESOLVED, that the Company’s stockholders hereby approve, on a non-binding, advisory basis, the compensation of the Company’s named executive officers, as disclosed in the Proxy Statement for the 2024 Annual Meeting of Stockholders, including the Compensation Discussion and Analysis, the Summary Compensation Table and other compensation tables, and the narrative disclosures that accompany the compensation tables.”
As this vote is advisory, it will not be binding upon the Board or the Compensation Committee, and neither the Board nor the Compensation Committee will be required to take any action as a result of the outcome of this vote. However, the Compensation Committee will carefully consider the outcome of this vote when considering future executive compensation policies and decisions.
Each year, we intend to submit the executive compensation of our named executive officers to an advisory vote at our annual meeting of stockholders, consistent with the “say-when-on-pay” recommendation from our stockholders at our 2022 annual meeting of stockholders, until such time as the say-when-on-pay proposal is brought before our stockholders again.
Vote Required and Recommendation
For approval, this proposal must receive the affirmative vote of the majority of shares properly cast on the proposal. Abstentions and broker non-votes will not be counted as votes cast on this proposal.
THE BOARD RECOMMENDS A VOTE “FOR” TO APPROVE, ON A NON-BINDING, ADVISORY BASIS, THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT.

CORPORATE GOVERNANCE AND BOARD MATTERS
Board Structure and Leadership
Our second amended and restated certificate of incorporation and amended and restated bylaws provide for a classified board of directors consisting of three classes of directors, each serving staggered three-year terms. As a result, one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Our directors are divided among the three classes as follows.
•    the Class I directors are Ms. Krishnan, Mr. Gangolli, and Ms. Mazzacco, and their terms will expire at the Annual Meeting and they will stand for reelection at the Annual Meeting;
•    the Class II directors are Mr. Janney, Mr. Rossi, and Dr. Sutherland, and their terms will expire at the 2025 annual meeting of stockholders; and
the Class III directors are Mr. Krishnan, Mr. Ganorkar, and Dr. Mason and their terms will expire at the 2026 annual meeting of stockholders.
Each director’s term continues until the election and qualification of his or her successor, or his or her earlier death, resignation or removal. Our second amended and restated certificate of incorporation and amended and restated bylaws authorize only our Board to fill vacancies on our Board. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors.
Combined Chairman and Chief Executive Officer Positions
Mr. Krishnan serves as the Chairman of the Board and Chief Executive Officer. The Board has reviewed its current leadership structure and has determined that the use of the lead independent director, as described below, along with the combined Executive Chairman and Chief Executive Officer positions, is currently the most appropriate and effective leadership structure for the Company. As the individual primarily responsible for the day-to-day management of business operations, Mr. Krishnan is best positioned to chair regular Board meetings as the directors discuss key business and strategic issues. Coupled with a lead independent director, this leadership structure allows the Board to exercise independent oversight and enables the Board to have direct access to information related to the day-to-day management of business operations.
Lead Independent Director
The Board believes that its governance structure ensures a strong, independent Board even though the Board does not have an independent Chairman. To strengthen the role of our independent directors and encourage independent Board leadership, the Board also has established the position of lead independent director, which currently is held by Mr. Janney. The responsibilities of the lead independent director include, among others:
•    presiding at all meetings of the Board at which the Chairman of the Board is not present;
•    scheduling meetings of the independent directors from time to time;
•    developing the agendas for, and presiding at, executive sessions of the independent directors of the Board;
•    communicating the sense of the independent directors to Mr. Krishnan;
•    assisting the Chairman of the Board to review and set the agenda and schedule for each of the Board’s meetings, including bringing to the attention of the Chairman of the Board particular issues for the Board’s attention and consideration and assuring there is sufficient time for discussion of all agenda items;
•    assisting in improving the effectiveness of Board meetings;
•    assisting the Chairman of the Board in the review and approval of information and materials to be sent to the Board, including in particular providing input as to the quality, quantity and timeliness of
12


the information submitted by the Company’s management that is necessary or appropriate for the independent directors to effectively and responsibly perform their duties; and
•    coordinating with committee chairpersons with respect to self-evaluations.
Director Independence
As required under NASDAQ listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. The Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities laws and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of NASDAQ, as in effect from time to time.
Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent registered public accounting firm, the Board has affirmatively determined that the following seven directors are independent directors within the meaning of the applicable NASDAQ listing standards and relevant securities laws: Messrs. Gangolli, Ganorkar, Janney, and Rossi, Drs. Mason and Sutherland, and Ms. Mazzacco. In making this determination, the Board considered all relationships and transactions that occurred during any 12-month period within the last three fiscal years and determined that there were no relationships that would interfere with their exercise of independent judgment in carrying out their responsibilities as directors.
Role of the Board in Risk Oversight
The role of our Board is to oversee the Chief Executive Officer and other senior management in the competent, lawful and ethical operation of the Company, including management’s establishment and implementation of appropriate practices and policies with respect to areas of potentially significant risk to us. Management routinely reports to the Board or committees of the Board regarding any potential areas of significant risk. These reports include discussions of current and new areas of potential operational, legal or financial risk and status reports on risk mitigation programs undertaken by us. The Board as a whole is responsible for such risk oversight but administers certain of its risk oversight with support from its three standing committees, the Audit Committee, the Nominating and Corporate Governance Committee, and the Compensation Committee, each of which addresses risks specific to their respective areas of oversight. In particular, our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function. Our Nominating and Corporate Governance Committee monitors the effectiveness of our Corporate Governance Guidelines, including whether they are successful in preventing illegal or improper conduct. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. 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. This is primarily due to the fact that our compensation program is 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.
Board Committees
Our Board has three standing committees: an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. We comply with the listing requirements and other rules and regulations of NASDAQ, as amended or modified from time to time, and each of these three committees is comprised exclusively of independent directors. Additionally, our Board may from time to time establish certain other committees to facilitate the management of our Company. In February 2021, our Board established the Science and Technology Committee and in March 2023, our Board established the Commercial Advisory Committee. The principal functions of each committee of the Board are described below.

Director Selection Process

The Nominating and Corporate Governance Committee is responsible for, among other things, the selection and recommendation to the Board of nominees for election as directors. In accordance with the Nominating and Corporate Governance Committee charter and our Corporate Governance Guidelines, the Nominating and Corporate Governance Committee develops guidelines and criteria for the selection of candidates for nominees for election as directors. The Nominating and Corporate Governance Committee considers whether a potential candidate for director has the time available, in light of other business and personal commitments, to perform the responsibilities required for effective service on the Board, along with their personal and professional integrity, demonstrated ability and judgment, experience, familiarity with the Company, diversity (of both experience and background, including gender, age, race, national origin, sexual orientation, and ethnicity) as well as certain other relevant factors. Applying these criteria, the Nominating and Corporate Governance Committee considers candidates for Board membership suggested by its members and the Chairman of the Board and Chief Executive Officer as well as stockholders. After completing the identification and evaluation process described above, the Nominating and Corporate Governance Committee recommends the nominees for directorship to the Board. Taking the Nominating and Corporate Governance Committee’s recommendation into consideration, the Board then approves the nominees for directorship for stockholders to consider and vote upon at the annual stockholders’ meeting.
Stockholders wishing to recommend individuals for consideration as directors must follow the procedures described in Section 2.9 of the Company’s amended and restated bylaws, including (among other requirements) the giving of written notice of the nomination to our Corporate Secretary not less than 90 days or more than 120 days prior to the one-year anniversary of the date on which the Company first mailed its proxy materials for the preceding year’s annual meeting of stockholders. The stockholder’s notice must set forth as to each nominee all information relating to the person that would be required to be disclosed in a solicitation of proxies for election of directors pursuant to Regulation 14A under the Exchange Act if the candidate had been nominated by or on behalf of the Board. Recommendations by stockholders that are made in this manner will be evaluated in the same manner as director candidates selected by the Nominating and Corporate Governance Committee. See “Other Matters—Stockholders Proposals and Nominations for the 2025 Annual Meeting.”

Commitment to Corporate Responsibility
Corporate responsibility is fundamental to our long-term success, and we are committed to building a sustainable business that provides long-term value for all of our stakeholders. Our mission is to develop and deliver genetic medicines to patients using redosable gene therapies for the treatment of severe, life‑threatening, and/or rare diseases that have limited or no approved therapies, and our diverse team of employees is committed to doing so sustainably and ethically, while using our resources to give back. We continue to advance our environmental, social and governance (“ESG”) practices. ESG oversight is exercised both at the Board of Directors level and through our executive leadership. The Nominating and Corporate Governance Committee of our Board of Directors has oversight responsibility regarding our ESG strategy and policies and is briefed by management on matters related to ESG. Our ESG program is centered around our commitment and responsibility to the patients we serve and their caregivers, the medical community, our employees, our communities in which we live and work, and business ethics and values. We take these commitments and responsibilities very seriously.
Our Commitment to Patients
Patients are at the center of our mission, and we are focused on making a difference for patients living with severe, life‑threatening, and/or rare diseases by discovering, developing, and delivering innovative genetic medicines. Our pioneering research in gene therapy has yielded the first approved genetic medicine for the treatment of wounds in patients with dystrophic epidermolysis bullosa (“DEB”), a serious rare skin disease caused by missing or mutated COL7 protein. In May 2023, the United States Food and Drug Administration (“FDA”) approved our genetic medicine, VYJUVEK® for the treatment of DEB, our first commercial product and the first-ever redosable gene therapy approved by the FDA. VYJUVEK is the only medicine for treatment of DEB that delivers the corrective power of gene therapy in an easy-to-apply, redosable, topical gel formulation that can be administered at home. We focus on creating an environment in which scientific and clinical innovation can thrive, and we have a robust clinical and preclinical pipeline.
16


We are committed to providing DEB patients with support and access to VYJUVEK to help them start and continue on treatment. Through Krystal ConnectTM, our personalized patient support program, we provide assistance throughout the treatment journey, including providing education about DEB and VYJUVEK, helping patients and caregivers understand and navigate insurance coverage, informing eligible patients about financial assistance programs, supporting VYJUVEK treatment planning and administration, and assisting patients with locating treating doctors. The Krystal Connect team includes community education liaisons who have backgrounds in nursing or genetic counseling and can answer questions about DEB and VYJUVEK, as well as patient access liaisons who assist patients who have been prescribed VYJUVEK navigate insurance coverage, financial assistance options for eligible patients, and treatment coordination.
We are committed to providing all DEB patients with access to VYJUVEK and have instituted philanthropic initiatives that provide financial assistance to eligible patients. With respect to financial assistance for VYJUVEK in the U.S., for eligible commercially insured patients, we have a copay program that can help reduce patients’ out-of-pocket costs to as low as $0. Additionally, for eligible patients without insurance coverage, or who may have insurance but do not have VYJUVEK coverage, our Patient Assistance Program may be able to provide VYJUVEK at no cost. Through our named patient program, we are able to supply VYJUVEK to DEB patients in countries outside of the U.S., where VYJUVEK is not yet commercially available. Additionally, through compassionate use programs, we have been able to address patient needs by making certain of our investigational products available to eligible patients, in accordance with applicable laws. We also have a genetic testing program to facilitate accurate diagnosis and delivery of optimal care.
Our patient-centric approach is enabled by the relationships fostered between our team and the patients, caregivers, and advocacy groups who experience these debilitating diseases on a day-to-day basis. These connections are especially valued in the rare disease setting. We partake in regular, compliant interaction with patient advocacy groups and invite patients to share their experiences in-person and virtually. Our ongoing interactions with patient advocacy groups and support programs help us to understand how we can continue to better serve our patients.
Our patients trust us to deliver products that are both safe and effective. We have policies that uphold the standards provided by the FDA to ensure quality, safe medicines. We take a proactive approach to ensure quality by prioritizing regulatory compliance and performing routine compliance checks, and we have established a Quality Management System, which ensures the highest quality standards. In addition, we have a system of robust processes to review, evaluate, and monitor the safety of VYJUVEK and our product candidates, and we are committed to continuous improvement.
Our Commitment to Our Employees and Diversity
Our future performance depends significantly upon the continued service of our employees and our continued ability to attract and retain highly skilled employees. We provide our employees with competitive salaries and bonuses, opportunities for equity ownership, development programs that enable continued learning and growth and a robust employment package that promotes well-being across all aspects of their lives. In addition to salaries, these programs include potential annual discretionary bonuses, stock options and restricted stock units awards, a 401(k) plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, and flexible work schedules, among other benefits. To promote engagement and well-being, our employees have access to our corporate wellness program and an onsite gym at our headquarters. We are committed to equitable pay, irrespective of gender identity or expression, race, ethnicity, sexual orientation, or other protected classes. Our executive team routinely reviews employee turnover throughout the organization to monitor employee satisfaction.
We strive to invest in and create ongoing opportunities for employee development to promote a respectful, diverse, and inclusive environment in which each team member plays a unique and vital role. We believe that a diverse workforce not only positively impacts our performance and strengthens our culture, but it also cultivates an essential pipeline of experienced leaders for management. Hiring for diversity of thought, background, experience, as well as personal characteristics such as gender identity and expression, race, ethnicity, faith, disability, veteran status, and LGBTQ+ identity, continues to be an area of focus as we grow our Company. Diversity starts at the top, where over half of the members of our Board of Directors identify as a member of an underrepresented racial/ethnic group, including our Chief Executive Officer and our President, R&D. In 2023, our employee population increased by 17%., and racially diverse employees made up approximately 21% of our
17


workforce. Our founder identifies as female and our team of senior leaders is diverse in both gender identity and race/ethnicity, as 66.7% of that group identifies as female and 66.7% of that same leadership group identifies as from racially/ethnically underrepresented groups.
We have formalized a set of corporate values to guide us in how we conduct our business and execute our corporate strategy:

Kindness
Respect
You (Authenticity)
Success
Teamwork
Accountability
Learning

Consistent with our “KRYSTAL” values, we believe a diverse and inclusive culture supports our ability to best serve patients. We are committed to our Diversity, Equity, and Inclusion (“DEI”) journey, and we have a team (our DEI Council) dedicated to our DEI strategy. The DEI Council works to foster a welcoming, diverse workplace where all employees can thrive and be their true selves. The DEI Council also spearheads inclusive hiring and business practices company-wide, improves upon employee engagement and psychological safety, and develops and sponsors training to counter unconscious bias, improve diversity, and create an equitable workplace. A wide range of leaders and employees at various levels and departments are members of our DEI Council. Our commitment to DEI is an ongoing journey, and we recognize there is always more to do. We continuously look for new ways to foster an inclusive and diverse culture to maintain the strongest possible team.
In addition to diversity in the workplace, we are committed to providing a diverse group of patients with access to our medicines, and we collaborate with numerous stakeholders to enable this access as appropriate. For example, for our pivotal Phase 3 (Gem 3) trial to evaluate the efficacy and safety of VYJUVEK, although DEB is a rare disease, we were able to recruit a study population where approximately 35% of the patients were non-white. We design our clinical trials to the highest ethical standards and to the extent possible, to reflect the target demographics of the disease state of the population.
Our Commitment to Our Communities and the Environment
We and our employees are actively involved in supporting our local and patient communities, including through charitable donations to patient advocacy groups. In 2023, we created a new philanthropy program known as the “Butterfly Effect” to support and make a difference in our communities through volunteering, making donations, and other ways of giving back. During 2023, our employees took part in many “Butterfly Effect” philanthropic activities, including volunteering at The Family House, which provides a safe, comforting, and affordable “home away from home” for patients and their families who travel to Pittsburgh hospitals for expert medical care; supporting TEAM DEBRA at the TD Five Boro Bike Tour in New York (debra of America is a national nonprofit organization dedicated to improving the lives of all people living with epidermolysis bullosa in the United States); donating school supplies to various non-profits such as the Education Partnership, the Children’s Advocacy Center, and Schools on Wheels, MA; and supporting the Greater Pittsburgh Community Food Bank and Feeding America by donating canned food and household items.
As a biotechnology company, our environmental footprint is relatively small in comparison to companies in many other industries, yet we are cognizant of our responsibility to our broader environment and have supported several green measures in an effort to reduce our Company’s carbon footprint, including increasing recycling and composting efforts, using energy-efficient rooftop HVAC units, and limiting waste in food service distribution. In our research laboratories and manufacturing facilities, hazardous waste is responsibly managed and tracked. Our second commercial scale Current Good Manufacturing Practice (“CGMP”) facility, ASTRA, a state-of-the-art 155,000 square foot CGMP manufacturing facility, is equipped with energy efficient systems to reduce environmental impact and carbon emissions and promote more cost-effective operations. We have also upgraded our corporate headquarters and our commercial scale CGMP-compliant manufacturing facility, ANCORIS, with new, more efficient equipment. In our manufacturing processes, we are committed to increasing efficiency, reducing materials, and minimizing waste. We have also taken steps to reduce environmental waste and increase environmental sustainability by reducing our use of paper by, for example, electronic delivery of this Proxy
18


Statement, and plastic. We have provided our employees with reusable water tumblers and ceramic coffee cups to encourage our employees to assist in preventing single use cups and plastic water bottle waste from entering the environment. We are committed to working with all of our stakeholders to understand and minimize our impact on the environment, and we continue to evolve our sustainability efforts, aiming for a long-term, sustainable future.
Our Commitment to Ethics, Values, and Corporate Governance
We are committed to conducting business ethically, responsibly, and transparently. We hold ourselves to the highest standards and have built strong governance practices to ensure accountability for our actions. All of our employees are required to adhere to our Code of Business Conduct and Ethics and are provided with training and reference materials to reinforce this commitment to integrity and ethics in our business. Our policies are clearly defined and include guidance on topics including, but not limited to, confidentiality; conflicts of interest; compliance with laws, rules, and regulations; fair dealing; antitrust compliance; accuracy of records; corporate disclosure; and improper payments.
We have implemented a comprehensive compliance program that has been designed to prevent and detect violations of Company policy or law through a proactive and practical training and communication approach and an open-door policy to discuss and report any concerns. In the event we become aware of potential compliance concerns, we will, where appropriate, take steps to investigate the matter, pursue disciplinary action, and/or implement corrective measures to prevent future issues. We also have robust policies in place to ensure compliant interactions with healthcare providers, protection of personal and patient data, and strong cybersecurity practices, among others.
Summaries of other corporate governance practices, including our Corporate Governance Guidelines, are included elsewhere in this Proxy Statement.

Executive Summary — Performance Highlights
Who We Are
We are a fully integrated, commercial-stage biotechnology company focused on the discovery, development, and commercialization of genetic medicines to treat diseases with high unmet medical needs. Our first commercial product, VYJUVEK, was approved by the FDA on May 19, 2023, and launched in the U.S. soon thereafter for the treatment of DEB, a serious rare skin disease caused by missing or mutated COL7 protein. VYJUVEK is the first medicine approved by the FDA for the treatment of DEB and the only medicine for treatment of DEB that delivers the corrective power of gene therapy in an easy-to-apply, redosable, topical gel formulation that can be administered at home.
Using our patented gene therapy technology platform that is based on engineered HSV-1, we create vectors that efficiently deliver therapeutic transgenes to cells of interest in multiple organ systems. The cell’s own machinery then transcribes and translates the encoded effector to treat or prevent disease. We formulate our vectors for non-invasive or minimally invasive routes of administration at a healthcare professional’s office or in the patient’s home by a healthcare professional. Our goal is to develop easy-to-use medicines to dramatically improve the lives of patients living with rare and serious diseases. Our innovative technology platform is supported by an in-house, FDA-inspected commercial scale CGMP manufacturing facility and a second, completed and qualified, commercial scale CGMP facility to support future expansion.
Performance Highlights
With the FDA approval and a successful commercial launch of VYJUVEK in the U.S., 2023 was a breakthrough year and an inflection point for the Company. Now, as a fully-integrated commercial-stage biotech with strong financial resources, VYJUVEK revenues, an FDA-approved redosable gene therapy platform, and two commercial-scale CGMP manufacturing facilities, we are well positioned for continued growth and to develop and bring to market highly differentiated, redosable gene therapies to treat many severe, life‑threatening, and/or rare diseases.
In addition to the FDA approval and commercial launch of VYJUVEK in the U.S., we achieved our other 2023 corporate goals and continued to make significant progress across both our pipeline and platform.
VYJUVEK (beremagene geperpavec-svdt, or B-VEC; referred to as B-VEC outside the U.S.)
On May 19, 2023, the FDA approved VYJUVEK, the first ever redosable gene therapy, for treating patients, six months of age or older, suffering from DEB. No clinical post-marketing commitments or Risk Evaluation and Mitigation Strategies program were required by the FDA. With the approval, the
24


FDA issued a Rare Pediatric Disease Voucher, or PRV, which confers priority review to a subsequent drug application that would not otherwise qualify for priority review. We sold the PRV in the third quarter of 2023 for $100.0 million.
Following FDA approval, we successfully launched VYJUVEK in the U.S., achieving $50.7 million in net product revenue for 2023. Additional highlights from our commercial launch include:
Gross margins of 93% in the fourth quarter of 2023.
Strong and sustained patient compliance to once weekly treatment while on VYJUVEK, with a 96% compliance rate for 2023.
Steady and strong progress in 2023 identifying patients, expanding and deepening our prescriber base, and securing broad access and reimbursement. As of February 2024, our prescriber base included over 195 prescribers, and we secured positive policies or coverage decisions from plans covering over 93% of commercial and Medicaid lives in the U.S., including positive coverage determinations from all major commercial national health plans and several regional health plans.
We also achieved multiple development milestones in 2023 as we worked to enable global access to B-VEC, including:
In October 2023, we submitted a marketing authorization application, or MAA, to the European Medicines Agency, or EMA, for B-VEC for the treatment of DEB in patients from birth. In November 2023, we were notified that the MAA had been validated and was now under Committee for Medicinal Products for Human Use review. We currently expect an EMA decision on our MAA in the second half of 2024.
In December 2023, B-VEC was granted Orphan Drug Designation status for the treatment of DEB by the Japan Ministry of Health, Labour and Welfare, a designation which confers specific benefits, including priority review of applications, extended registration validity, and reduced development costs. We also initiated an open label extension study of B-VEC in Japan in 2023 to support regulatory approval. This study is fully enrolled and we anticipate filing a Japan New Drug Application in the second half of 2024 enabling a potential authorization in 2025.
Respiratory
KB407 is an inhaled (nebulized) formulation of our novel vector designed to deliver two copies of the full-length CFTR transgene for the treatment of cystic fibrosis, a serious rare lung disease caused by missing or mutated CFTR protein.
In July 2023, we dosed the first patient in our Phase 1 CORAL-1 study evaluating KB407, delivered via a nebulizer, for the treatment of patients with cystic fibrosis. The CORAL-1 study is a multi-center, dose-escalation trial of KB407 in patients with cystic fibrosis, regardless of their underlying genotype. In the fourth quarter of 2023, we completed the first cohort of the CORAL-1 study with no severe or serious adverse events and, in January 2024, we initiated dosing in the second of three cohorts.
KB408 is an inhaled (nebulized) formulation of our proprietary vector, designed to deliver two copies of the SERPINA1 transgene that encodes functional, full-length human alpha-1- antitrypsin protein, for the treatment of alpha-1 antitrypsin deficiency, or AATD, a serious lung disease that can result in life threatening, progressive pulmonary impairment and severe respiratory insufficiency.
In September 2023, the FDA accepted our investigational new drug, or IND, application to evaluate KB408, delivered via a nebulizer, in a clinical trial to treat patients with AATD. In early 2024, we dosed the first patient in our KB408 Phase 1 clinical study and intend to announce interim data from the study in the second half 2024.

Ophthalmology
Ophthalmic B-VEC is a redosable eye drop formulation of B-VEC, designed to deliver two copies of the COL7A1 transgene to the epithelial cells in a patient’s eye to produce COL7 protein, to treat ocular complications of DEB, such as corneal erosions, abrasions, blistering, and scarring, that can lead to progressive vision loss.
In April 2023, we announced clinical data on the compassionate use of B-VEC, administered as an eye drop, to treat a patient suffering from ocular complications of DEB. Data was subsequently published in the New England Journal of Medicine in February 2024. Regular application of B-VEC to the eye was well tolerated and associated with full corneal healing at three months and visual acuity improvement from hand motion to 20/25 by eight months.
The FDA has agreed with our proposed single arm, open label study in approximately 10 patients to enable approval of B-VEC eyedrops, and we plan to initiate this study in the second half 2024.
Oncology
KB707 is a redosable, immunotherapy designed to deliver genes encoding both human IL-2 and IL-12 to the tumor microenvironment and promote systemic immune-mediated tumor clearance. Two formulations of KB707 are in development, a solution formulation for transcutaneous injection and an inhaled (nebulized) formulation for lung delivery.
In July 2023, the FDA granted intratumoral KB707 Fast Track Designation for the treatment of anti-PD-1 relapsed/refractory locally advanced or metastatic melanoma and accepted our IND application to evaluate intratumoral KB707 in a clinical trial to treat patients with locally advanced or metastatic solid tumors. The study, OPAL-1, is an open-label, multi-center, monotherapy, dose escalation and expansion Phase 1 study, enrolling patients with locally advanced or metastatic solid tumors, who relapsed or are refractory to standard of care, with at least one measurable and injectable tumor accessible by transcutaneous route.
In October 2023, we dosed the first patient in the OPAL-1 study. Enrollment is ongoing.
In December 2023, we submitted to the FDA an amendment to our IND application to evaluate inhaled KB707 in a clinical trial to treat patients with locally advanced or metastatic solid tumors of the lung. The FDA accepted the amendment in January 2024. The study, KYANITE-1, is an open-label, multi-center, monotherapy, dose escalation and expansion Phase 1 study. We plan on initiating the KYANITE-1 study in the first half of 2024. Inhaled KB707 also received Fast Track Designation from the FDA for the treatment of patients with solid tumors with pulmonary metastases that are relapsed or refractory to standard of care therapy.
Aesthetics
KB301 is a solution formulation of our novel vector for intradermal injection designed to deliver two copies of the COL3A1 transgene to address signs of aging or damaged skin caused by declining levels of, or damaged proteins within the extracellular matrix, including type III collagen.
In April 2023, Jeune Aesthetics, Inc. (“Jeune Aesthetics”), our wholly-owned subsidiary, initiated and treated the first subject in the PEARL-1 Cohort 3 clinical study. The PEARL-1 Cohort 3 study is an open label study to evaluate different doses of KB301 for the improvement of lateral canthal lines at rest in up to 20 subjects.
Jeune Aesthetics has also initiated and treated the first subject in the PEARL-1 Cohort 4 clinical study, an open label study to evaluate KB301 for the improvement of dynamic wrinkles of the décolleté in up to 20 subjects. Cohort 4 is running simultaneously with the Cohort 3 study, and Jeune Aesthetics expects to announce results for both cohorts in the first half of 2024.
Other 2023 Performance Highlights
In August 2023, we began research and development operations in our second commercial scale CGMP biologics manufacturing facility, ASTRA, a 155,000 sq. ft. state-of-the-art CGMP facility with comprehensive end-to-end capabilities.
26


We ended 2023 with cash, cash equivalents and investments of $594.1 million.
We continued to build on our existing capabilities and grew our organization in the United States and abroad.
Executive Compensation Highlights
Based on our overall operating environment and the performance results highlighted above, the Compensation Committee took the following key actions with respect to the compensation of our Named Executive Officers for and during 2023:
•    Base Salaries. Paid an annual base salary of $733,333 for our CEO and approved annual base salary increases ranging from 5.6% to 14.6% for our other Named Executive Officers.
•    Performance-Based Annual Cash Bonus Opportunities. Approved target annual cash bonus opportunities for our Named Executive Officers under our performance-based annual cash bonus plan in amounts equal to 65% of his 2023 annual base salary for our CEO and 50% of their 2023 annual base salaries for our other Named Executive Officers.

•    Performance-Based Annual Cash Bonus Awards. Under the 2023 annual bonus plan, Named Executive Officers other than our CEO were eligible to earn cash bonus awards based 75% on our corporate performance and 25% on individual performance. Our CEO’s annual cash bonus award was based 100% on our corporate performance. Based on our achieving 100% of corporate performance and 120% of individual performance for Ms. Krishnan and 120% of individual performance for Ms. Romano, our Named Executive Officers earned on average 103% of their target annual incentive bonus opportunities. The actual annual bonus paid to the Named Executive Officers under our 2023 annual bonus plan was $487,500 for our CEO, $307,125 for Ms. Krishnan, and $210,000 for Ms. Romano. Mr. Orth resigned from his position with the Company in August 2023 and was not eligible to receive a cash bonus under our 2023 annual bonus plan.

•    Long-Term Incentive Compensation. Granted long-term incentive compensation opportunities in the form of options to purchase shares of our Common Stock if vesting requirements are met and performance-based restricted stock units (“PSUs”) that are settled in shares of our Common Stock if performance objectives and vesting requirements are achieved. Our CEO received an award of 50,000 options to purchase shares of our Common Stock and an award of 25,000 PSUs. Ms. Krishnan received an award of 30,000 options to purchase shares of our Common Stock and an award of 15,000 PSUs. Mr. Orth and Ms. Romano each received an award of 20,000 options to purchase shares of our Common Stock and an award of 10,000 PSUs.
Relationship Between Pay and Performance
We believe our executive compensation program is reasonable, competitive, and appropriately balances the goals of attracting, motivating, rewarding, and retaining our executive officers with the goal of aligning their interests with those of our stockholders. To ensure this alignment and to motivate and reward individual initiative and effort, we seek to ensure that a meaningful portion of our executive officers’ target annual direct compensation opportunity is both variable in nature and “at-risk.”
We emphasize variable compensation that appropriately rewards our Named Executive Officers through two separate compensation elements:
•    First, we provide the opportunity to participate in our performance-based annual cash bonus plan which provides cash payments if we produce short-term financial, operational, and/or strategic results that meet or exceed pre-established corporate goals as determined by our Compensation Committee and includes the evaluation of certain individual contributions in achieving those goals for all Named Executive Officers, other than our CEO whose performance-based annual cash bonus is based 100% on our corporate performance against pre-established corporate goals.
•    In addition, in 2023, we granted options to purchase shares of our Common Stock and PSUs, and, in 2021, we granted Restricted Stock Awards (“RSAs”), which equity awards comprise a majority of the
27


Named Executive Officers’ target total direct compensation opportunities. The value of these equity awards depends entirely on the value of our common stock, thereby incentivizing our Named Executive Officers to build sustainable long-term value for the benefit of our stockholders.
These variable pay elements ensure that a substantial portion of our Named Executive Officers’ target total direct compensation is contingent (rather than fixed) in nature, with the amounts ultimately payable subject to variability commensurate with our actual performance.
In 2023, approximately 87% of our CEO’s and approximately 85% (on average) of our other Named Executive Officers’ total direct compensation consisted of “at risk,” variable compensation.
We believe that this design provides balanced incentives for our Named Executive Officers to execute our financial, operational, and strategic objectives and drive long-term growth. To ensure that we remain faithful to our compensation philosophy, the Compensation Committee regularly evaluates the relationship between the reported values of the equity awards granted to our Named Executive Officers, the amount of compensation realizable (and, ultimately, realized) from such awards in subsequent years, and our Named Executive Officers’ performance.
Executive Compensation Policies and Practices
We endeavor to maintain sound governance standards consistent with our executive compensation policies and practices. The Compensation Committee reviews our executive compensation program on an annual basis to ensure consistency with our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent. The following summarizes our executive compensation-related policies and practices that were in effect during 2023:
What We Do:
•    Maintain Independent Compensation Committee. The Compensation Committee is comprised solely of independent directors who determine our compensation policies and practices and who have established effective means for communicating with our stockholders regarding their executive compensation views and concerns, as described in this Proxy Statement.
•    Retain an Independent Compensation Consultant. The Compensation Committee engaged its own independent compensation consultant to provide information and analysis with its 2023 compensation review, and other advice on executive compensation.
Review of Compensation Peer Group. Our compensation peer group is reviewed at least annually by the Compensation Committee and adjusted, when necessary, to help ensure that its composition remains a relevant and appropriate comparison for our executive compensation programs.
Review of Compensation Committee Charter. The Compensation Committee reviews its charter annually to consider the incorporation of best governance practices.
Conduct an Annual Say-on-Pay Vote. In accordance with our stockholders’ recommendation, we hold say-on-pay votes on an annual basis.
•    Annual Executive Compensation Review. The Compensation Committee reviews and approves our compensation strategy annually, including a review of the relationship between executive compensation and the Company’s performance, our compensation peer group used for comparative purposes, and a review of our compensation-related risk profile to ensure that our compensation programs do not encourage excessive or inappropriate risk-taking and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on the Company.
•    Compensation At-Risk. Our executive compensation program is designed so that a significant portion of our Named Executive Officers’ compensation is “at risk” based primarily on corporate performance, as well as equity-based, to align the interests of our Named Executive Officers and stockholders.
Clawbacks. In 2023, the Company adopted a new executive compensation Clawback Policy.
28


•    Multi-Year Vesting Requirements. The annual equity awards granted to our Named Executive Officers vest over multi-year periods, consistent with current market practice and our retention objectives.
•    Health and Welfare Benefits. Our Named Executive Officers participate in broad-based Company-sponsored health and welfare benefit programs on the same basis as our other full-time, salaried employees.
What We Don’t Do:
•    No Executive Pension Plans or Supplemental Retirement Plans. We do not currently offer, nor do we have plans to offer, defined benefit pension plans or any non-qualified deferred compensation plans or arrangements to our Named Executive Officers other than the plans and arrangements that are available to all employees. Our Named Executive Officers are eligible to participate in our Section 401(k) retirement plan on the same basis as our other employees. We do not provide any supplemental retirement plans.
•    No Guaranteed Cash Payments. We do not provide our Named Executive Officers with guaranteed base salary increases or performance-based annual bonus increases.
•    Limited Perquisites. We provide minimal perquisites and other personal benefits to our Named Executive Officers.
•    No Tax Payments on Perquisites. We do not provide any tax reimbursement payments (including “gross-ups”) on any perquisites or other personal benefits, other than on standard relocation benefits.
•    No Tax Payments on Change-in-Control Arrangements. We do not provide any excise tax reimbursement payments (including “gross-ups”) on payments or benefits contingent upon a change in control of the Company.
•    No Hedging or Pledging of our Equity Securities. We maintain a policy that prohibits our employees, including our Named Executive Officers, and the non-employee members of our Board of Directors from hedging or pledging our equity securities.
No Re-pricing of Stock Options. We do not re-price stock options without stockholder approval, and we do not grant discounted stock options.
Stockholder Advisory Vote on Named Executive Officer Compensation
We value the opinions of our stockholders. At our 2023 annual meeting of stockholders, we conducted a non-binding advisory vote on the compensation of our Named Executive Officers, commonly referred to as a “say-on-pay” vote, in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Over 95% of the votes cast by stockholders on this proposal, excluding broker non-votes and abstentions, were cast in support of the compensation paid to our Named Executive Officers. While this vote is a non-binding advisory vote, our Compensation Committee and Board take the voting results into account in determining the compensation of our Named Executive Officers. In light of the level of support evidenced by last year’s say-on-pay vote, among other factors, our Compensation Committee decided to maintain our general approach to executive compensation and made no significant changes to our executive compensation program for 2023.
In addition, at our 2022 annual meeting of stockholders, we asked that our stockholders recommend, on an advisory basis, whether we hold future say-on-pay votes annually, every two years or every three years. Of the votes cast, there was a large preference for an annual say-on-pay vote. After consideration of these results, it was decided, in accordance with stockholders’ recommendation, that we will hold future say-on-pay votes on an annual basis until the occurrence of the next advisory vote on the frequency of say-on-pay votes. Our Compensation Committee and Board will continue to consider stockholder input and monitor our executive compensation program to ensure it aligns the interests of our Named Executive Officers with the interests of our stockholders and adequately addresses input from our stockholders. Accordingly, at the Annual Meeting to which this Proxy Statement relates, we will be conducting a non-binding vote on the compensation of our Named Executive Officers disclosed in this Proxy Statement. See Proposal 3 in this Proxy Statement.

Executive Compensation Philosophy and Objectives
Our executive compensation program is guided by our overarching philosophy of paying for demonstrable performance. We strive to provide an executive compensation program that is competitive, rewards achievement of our business objectives, and aligns our executive officers’ interests with those of our stockholders. Consistent with this philosophy, we have designed our executive compensation program to achieve the following primary objectives:
•    provide market competitive compensation and benefit levels that will attract, motivate, reward, and retain a highly talented team of executives within the context of responsible cost management;
•    motivate and reward behavior consistent with our corporate performance objectives; and
•    ensure that our compensation is meaningfully tied to the creation of sustainable long-term stockholder value.
Executive Compensation Design
We structure the annual compensation of our Named Executive Officers using three principal elements: base salary, performance-based annual cash bonus opportunities, and long-term incentive compensation opportunities in the form of equity awards. The design of our executive compensation program is influenced by a variety of factors, with the primary goals being to align the interests of our Named Executive Officers and stockholders and to link pay with performance.
We emphasize the use of equity awards to provide incentives for our Named Executive Officers to focus on the growth of our overall enterprise value and, correspondingly, to create value for our stockholders. The longer-term nature of these equity awards mirror our long-term investment in bringing new therapies to market, and incentivize continuity of leadership over the long-term.
For 2023, our long-term incentive compensation awards granted to our Named Executive Officers consisted of stock options and PSUs. Our Board and the Compensation Committee believe that options to purchase shares of our Common Stock are a key tool in serving to align the interests of our Named Executive Officers and our stockholders. In 2023, the Compensation Committee introduced PSU awards as part of our long-term incentive compensation opportunities to further align the interests of our Named Executive Officers with our stockholders. We believe our equity awards facilitate retention and align the interests of our Named Executive Officers’ with those of our stockholders by allowing them to participate in our longer-term success and the intended appreciation of our stock price.
Stock options are inherently performance based, and link executive pay to stockholder return. With stock options, our Named Executive Officers will receive value from their awards only if the market price of our Common Stock increases above the exercise price and remains above the exercise price as the stock options vest, which focuses our Named Executive Officers on long-term stockholder value creation. Stock options do not offer downside protection, and, thus, will not provide value to our Named Executive Officers if the market price of our Common Stock is below the exercise price.
PSUs provide for alignment of our Named Executive Officers’ compensation with the Company’s performance. PSUs are also only eligible to vest if the Compensation Committee determines that specific objectives have been achieved, which may include financial, commercial, clinical, regulatory, operational, and/or business development objectives. Accordingly, PSUs provide incentives that (i) are tied to the Company’s performance and (ii) encourage our Named Executive Officers to continue providing services to us through the vesting period, and both of these components align the interests of our Named Executive Officers with those of our stockholders.
In 2021, our long-term incentive compensation opportunities included RSAs. RSAs provide our Named Executive Officers with an economic benefit equal to the portion of the RSA that vests annually. This provides incentives for our Named Executive Officers to continue to create stockholder value over time and with the downside protection that the RSA will retain some value, it also provides an incentive for our Named Executive Officers to continue providing services to us through the vesting period.
We have not adopted formal policies or guidelines for allocating compensation between current and long-term compensation, between cash and non-cash compensation or among different forms of non-cash compensation. As
30


described below, the Compensation Committee considers a variety of factors in determining the appropriate yearly mix among such compensatory elements.
Compensation-Setting Process
Role of Compensation Committee
The Compensation Committee discharges the responsibilities of our Board relating to the compensation of our Named Executive Officers and the non-employee members of our Board. The Compensation Committee has the overall responsibility for overseeing our compensation and benefits policies and overseeing and evaluating the compensation plans, policies, and practices applicable to our Named Executive Officers.
In carrying out its responsibilities, the Compensation Committee evaluates our compensation policies and practices with a focus on the degree to which these policies and practices reflect our executive compensation philosophy, develops strategies and makes decisions that it believes further our philosophy or align with developments in best compensation practices, and reviews the performance of our Named Executive Officers when making decisions with respect to their compensation.
The Compensation Committee’s authority, duties, and responsibilities are further described in its charter, which is available on our website at www.krystalbio.com under “Corporate Governance” on the “Investors” page.
The Compensation Committee retains an independent compensation consultant (as described below) to provide support in its review and assessment of our executive compensation program; however, the Compensation Committee exercises its own judgment in making final decisions with respect to the compensation of our Named Executive Officers.
The Compensation Committee reviews our executive compensation program annually. As part of this review process, the Compensation Committee applies the objectives described above within the context of our overall compensation philosophy while simultaneously considering the compensation levels needed to ensure our executive compensation program remains competitive based on input from and market data provided by the Compensation Committee’s compensation consultant. The Compensation Committee also evaluates whether we are meeting our retention objectives and the potential cost of replacing key Named Executive Officers.
Setting Target Total Direct Compensation

Each year, typically during the first quarter of the fiscal year, the Compensation Committee conducts a review of our Named Executive Officers’ compensation arrangements. As part of this review, the Compensation Committee evaluates the base salary levels, performance-based annual cash bonus opportunities, and long-term incentive compensation opportunities of our Named Executive Officers and all related performance criteria.
The Compensation Committee does not establish a specific target for formulating the target total direct compensation opportunities of our Named Executive Officers. Instead, it evaluates both performance and compensation to ensure that the compensation provided to our Named Executive Officers is competitive relative to the compensation paid by similar companies in the biotechnology and pharmaceuticals sectors, with particular emphasis on our peer companies, as described below.
In making decisions about the compensation of our Named Executive Officers, the members of the Compensation Committee rely primarily on their general experience and subjective considerations of various factors, including the following:
•    our executive compensation program objectives;
•    our performance against the financial, operational, and strategic objectives established by the Compensation Committee;
•    each individual Named Executive Officer’s knowledge, skills, experience, qualifications, and tenure relative to other similarly situated executives at the companies in our compensation peer group and/or the proprietary database of the Compensation Committee’s independent compensation consultant;
31


•    the scope of each Named Executive Officer’s role and responsibilities compared to other similarly situated executives at the companies in our compensation peer group and/or the proprietary database of the Compensation Committee’s independent compensation consultant;
•    the prior performance of each individual Named Executive Officer, based on a subjective assessment of his or her contributions to our overall performance, ability to lead his or her business unit or functions and work as part of a team, all of which reflect our core values;
•    the potential of each individual Named Executive Officer to contribute to our long-term financial, operational, and strategic objectives;
•    our CEO’s compensation relative to that of our other Named Executive Officers, and compensation parity among our executive officers;
•    the compensation practices of our compensation peer group and the companies in selected broad-based compensation surveys and the positioning of each Named Executive Officer’s compensation in a ranking of peer company compensation levels based on an analysis of competitive market data; and
•    the recommendations of our CEO with respect to the compensation of our other Named Executive Officers.
These factors provide the framework for compensation decision-making and final decisions regarding the compensation opportunities for each Named Executive Officer. No single factor is determinative in setting compensation levels, nor is the impact of any individual factor on the determination of pay levels quantifiable.
The Compensation Committee does not weigh these factors in any predetermined manner, nor does it apply any formulas in developing its compensation decisions. In making compensation decisions, the members of the Compensation Committee consider these factors in light of the members individual experience, knowledge of the Company, knowledge of the competitive market, knowledge of each Named Executive Officer, and business judgment.

The Compensation Committee does not engage in formal benchmarking against other companies’ compensation programs or practices to establish our compensation levels or to make specific compensation decisions with respect to our Named Executive Officers. Instead, in making its determinations, the Compensation Committee reviews information summarizing the compensation paid at a representative group of peer companies, the extent to which the executive positions at these companies are considered comparable to our positions and informative of the competitive environment and more broad-based compensation surveys. Broad-based compensation surveys allow the Compensation Committee to gain a general understanding of market compensation levels.
Role of Management
In discharging its responsibilities, the Compensation Committee works with members of our management, including our CEO. Our management assists the Compensation Committee by providing information on corporate and individual performance, market compensation data, and management’s perspective on compensation matters. The Compensation Committee solicits and reviews our CEO’s proposals with respect to program structures, as well as his recommendations for adjustments to annual cash compensation, long-term incentive compensation opportunities, and other compensation-related matters for our other Named Executive Officers based on his evaluation of their performance for the prior year.

At the beginning of each year, our CEO reviews the performance of our other Named Executive Officers, including each such individual’s level of success in accomplishing the business objectives established for him or her for the prior year and his or her overall performance during that year, and then shares these reviews with, and makes recommendations to, the Compensation Committee. The CEO’s recommendations include a recommendation for each element of compensation, as the elements are described above. The annual business objectives for each Named Executive Officer are developed through mutual discussion and agreement between our CEO and the Named Executive Officers and take into account our business objectives, which are reviewed with the Compensation Committee.
32


The Compensation Committee reviews and discusses the CEO’s proposals and recommendations with our CEO and considers them as one factor in determining and approving the compensation of our other Named Executive Officers. Our CEO also attends meetings of our Board and the Compensation Committee at which executive compensation matters are addressed, except with respect to discussions involving his own compensation.
Role of Compensation Consultant
The Compensation Committee has the sole authority to retain an external compensation consultant to assist it by providing information, analysis, and other advice relating to our executive compensation program. The Compensation Committee also has the authority to approve the consultant’s reasonable fees and other retention terms. The compensation consultant reports directly to the Compensation Committee and its chair, and serves at the discretion of the Compensation Committee, which reviews the engagement annually.
In 2023, the Compensation Committee engaged Compensia, Inc. (“Compensia”), a national compensation consulting firm, to serve as its compensation consultant to advise on executive compensation matters, including competitive market pay practices for our Named Executive Officers, and with the selection of our compensation peer group.
During 2023, Compensia provided various services including the following:
•    the review, analysis, and recommended updating of our compensation peer group;
•    the review and analysis of the base salary levels, performance-based annual cash bonus opportunities, and long-term incentive compensation opportunities of our Named Executive Officers against competitive market data based on the companies in our compensation peer group and Compensia's proprietary database;
•    consultation with the Compensation Committee chair; and
•    support on other ad hoc matters throughout the year.
Compensia also coordinated with our management for data collection and informal market comparisons for our Named Executive Officers. In 2023, Compensia did not provide any other services to us.
The Compensation Committee has evaluated its relationship with Compensia to ensure that it believes that such firm is independent from management. This review process included a review of the services that such compensation consultant provided, the quality of those services and the fees associated with the services provided during 2023. Based on this review, as well as consideration of the factors affecting independence set forth in Exchange Act Rule 10C-1(b)(4), Rule 5605(d)(3)(D) of the NASDAQ Marketplace Rules, and such other factors as were deemed relevant under the circumstances, the Compensation Committee has determined that no conflict of interest was raised as a result of the work performed by Compensia.
Competitive Positioning
The Compensation Committee believes that peer group comparisons are useful guides to evaluate the competitiveness of our executive compensation program and related policies and practices. For purposes of assessing our executive compensation against the competitive market, the Compensation Committee reviews and considers the compensation levels and practices of a select group of peer companies. This compensation peer group consists of biotechnology and pharmaceutical companies that are similar to us in terms of market capitalization and stage of development. The competitive data drawn from this compensation peer group is one of several factors that the Compensation Committee considers in making its decisions with respect to the compensation of our Named Executive Officers.
The compensation peer group for 2023, which was updated in December 2022 with the assistance of Compensia, to analyze the compensation of our Named Executive Officers was comprised of publicly traded biotechnology and pharmaceutical companies against which we compete for executive talent. In identifying and selecting the companies to comprise the compensation peer group, Compensia considered the following primary criteria:
•    similar industry – companies with a primary focus in the biotechnology and pharmaceutical sectors;
33


•    similar market capitalization – within a range of ~0.33x to ~3.0x of our then-market capitalization of approximately $2.0 billion;
•    FDA Phase – companies pending FDA approval, or early commercial (<$250 million revenue); and
Refinement criteria – gene/cell therapy, or orphan designation/rare disease – to help identify those companies most similar to us.
After evaluating the 2022 peer companies against these criteria, the Compensation Committee replaced 10 of the companies in our peer group, as being below our market capitalization range, outside our phase of development, or having been acquired. The compensation peer group for 2023 pay decisions consisted of the following companies:
Agios Pharmaceuticals
BridgeBio Pharma*
Intra-Cellular Therapies*
Alector
Crinetics Pharmaceuticals
Mirati Therapeutics*
AlloVir
Cytokinetics*
REGENXBIO
Apellis Pharmaceuticals*
Denali Therapeutics*
Sorrento Therapeutics
BioCryst Pharmaceuticals*
ImmunityBio*
SpringWorks Therapeutics
Blueprint Medicines*
Insmed*
*New for 2023
  
The Compensation Committee used data drawn from the companies in our compensation peer group, as well as data drawn from Compensia’s proprietary database, to evaluate the competitive market when determining the total direct compensation packages for our Named Executive Officers, including base salary, target performance-based annual cash bonus opportunities, and long-term incentive compensation opportunities.
The Compensation Committee reviews our compensation peer group at least annually and makes adjustments to its composition if warranted, taking into account changes in both our business and the businesses of the companies in the peer group.
Compensation Elements
Generally, our executive compensation program consists of three principal elements – base salary, performance-based annual cash bonus opportunity, and long-term incentive compensation in the form of equity awards. It also includes participation in our broad-based health and welfare benefit programs.

Base Salary
Base salary represents the fixed portion of the compensation of our Named Executive Officers and is an important element of compensation intended to attract and retain highly talented individuals. We use base salary to provide
34


each Named Executive Officer with a specified level of cash compensation during the year with the expectation that he or she will perform his or her responsibilities to the best of his or her ability and in our best interests.
Generally, we establish the initial base salaries of our Named Executive Officers through arm’s-length negotiation at the time we hire the individual, taking into account his or her position, qualifications, experience, prior salary level, and the base salaries of our other executive officers. Thereafter, the Compensation Committee reviews the base salaries of our Named Executive Officers each year as part of its annual review of our executive compensation program, with input from our CEO (except with respect to his own base salary) and makes adjustments as it determines to be reasonable and necessary to reflect the scope of a Named Executive Officer’s performance, individual contributions and responsibilities, position in the case of a promotion, and market conditions.
In February 2023, the Compensation Committee reviewed the base salaries of our Named Executive Officers, taking into consideration a competitive market analysis prepared by Compensia and the recommendations of our CEO (except with respect to his own base salary), as well as the other factors described in “Compensation-Setting Process – Setting Target Total Direct Compensation” above. Following this review, the Compensation Committee determined to adjust the base salaries of each of our Named Executive Officers to better reflect the
competitive marketplace.

The base salaries of our Named Executive Officers as approved by the Compensation Committee in February 2022 and 2023 were as follows:

The base salaries paid to our Named Executive Officers during 2023 are set forth in the “Summary Compensation Table” below.
Performance-Based Annual Cash Bonuses

We provide our Named Executive Officers with the opportunity to earn annual cash bonuses that are intended to encourage the achievement of corporate performance goals, which could include goals related to commercializing our products, advancing our clinical pipeline, building our research and development and manufacturing infrastructure, strategic initiatives, financial performance, and growing and sustaining the Company. Cash bonuses for our Named Executive Officers other than our CEO for 2023 were based 75% on our corporate performance and 25% on individual performance. The cash bonus for our CEO was based 100% on our corporate performance. The corporate performance multiplier is based on the degree to which the Company’s objectives have been achieved during the relevant year; this multiplier is determined by the Compensation Committee and for 2023 could have ranged from 0 to 125% of target. The individual performance multiplier is based on the degree to which each employee’s individual objectives have been achieved during the relevant year; this
35


multiplier is approved by the Compensation Committee for each of our Named Executive Officers and for 2023 could have ranged from 0 to 120% of target. To be eligible to receive an annual cash bonus payment, a Named Executive Officer must be employed by us through the time of the bonus payment.
Target Annual Cash Bonus Opportunities
In February 2023, the Compensation Committee reviewed the target annual cash bonus opportunities of our Named Executive Officers as part of its annual review of our executive compensation program. For purposes of this review, the Compensation Committee took into consideration a competitive market analysis prepared by Compensia and the recommendations of our CEO (except with respect to his own target annual cash bonus opportunity), as well as the other factors described in “Compensation-Setting Process – Setting Target Total Direct Compensation” above.
The target annual cash bonus opportunities of our Named Executive Officers for 2023, both as a percentage of annual base salary and in dollars are set forth below.

Corporate Performance Goals
Corporate performance goals for our annual cash bonus opportunity were approved by the Compensation Committee in February 2023 and related to operational and strategic objectives that were important to us, including commercializing VYJUVEK, advancing our clinical pipeline, and corporate goals. These corporate performance goals include highly-sensitive competitive data, and we do not disclose the specific goals or targets because we believe that such disclosure would result in competitive harm to us. The Compensation Committee purposely set these goals at challenging levels.
Annual Cash Bonus Payments
In January 2024, the Compensation Committee evaluated our actual performance against the corporate performance goals and determined that we had achieved such goals at 100% of their target level, resulting in a corporate performance multiplier of 100%.
In addition, our CEO assessed the individual performance of each of our other Named Executive Officers and provided these assessments to the Compensation Committee. The Compensation Committee reviewed our CEO's assessments and determined that, each of Suma Krishnan and Kathryn Romano had achieved 120% of their target individual performance goals. Mr. Orth resigned from his position in August 2023 and was not eligible to receive an annual cash bonus for his service in 2023.

In view of such achievement, the Compensation Committee determined to make annual cash bonus payments to our Named Executive Officers as follows:

The annual bonuses awarded to our Named Executive Officers for 2023 are set forth in the “Summary Compensation Table” below.
Long-Term Equity Incentive Compensation
As a biotechnology company that encounters significant competition for qualified personnel, long-term incentive compensation plays a critical role in our ability to attract, hire, motivate, and reward qualified and experienced executives. The use of long-term incentive compensation in the form of equity awards is necessary for us to compete for qualified executives without significantly increasing cash compensation and is the most important element of our executive compensation program. We use equity awards to incentivize and reward our Named Executive Officers for long-term corporate performance based on the value of our Common Stock and, thereby, to align their interests with the interests of our stockholders. The realized value of these equity awards bears a direct relationship to our stock price, and, therefore, these awards are an incentive for our Named Executive Officers to create value for our stockholders. Equity awards that vest over time also help us retain our Named Executive Officers in a highly competitive market.
In 2023, we used options to purchase shares of our Common Stock and PSUs that are settled in shares of our Common Stock to motivate and reward our Named Executive Officers for long-term increases in the value of our Common Stock. The Compensation Committee believes that because stock options provide an economic benefit only in the event that our stock price increases over the exercise price of the option, these awards align the interests of our Named Executive Officers with those of our stockholders. PSU awards granted to our Named Executive Officers vest only after the achievement of specified performance objectives approved by the Compensation Committee, which are set at challenging levels. Accordingly, the Compensation Committee believes that PSU awards provide meaningful incentives to our Named Executive Officers to increase the value of our stock over time. In addition, the vesting feature of PSU grants contributes to retention of our Named Executive Officers by providing an incentive to our Named Executive Officers to remain employed with us during the vesting period. The Compensation Committee determined that the equity mix for our Named Executive Officers’ 2023 equity awards (through stock options and PSUs) was appropriate to ensure that the compensation of our Named Executive Officers remains tied to stock performance and achievement of meaningful corporate goals and that it also promotes retention.
In 2023, the Compensation Committee did not apply a rigid formula in determining the size of the equity awards to be granted to our Named Executive Officers. Instead, in making these decisions, the Compensation Committee exercised its judgment as to the amount of the awards after considering a competitive market analysis prepared by Compensia, the outstanding equity holdings of each Named Executive Officer (including the current economic value of his or her unvested equity holdings and the ability of these unvested holdings to satisfy our retention objectives), the proportion of our total shares of our Common Stock outstanding used for annual employee long-term incentive compensation awards (our “burn rate”) in relation to the annual burn rate ranges of the companies in our compensation peer group, the potential voting power dilution to our stockholders in relation to the median practice of the companies in our compensation peer group, and the other factors described in “Compensation-Setting Process — Setting Target Total Direct Compensation” above. Based upon these factors, the
37


Compensation Committee determined the size of each award at levels it considered appropriate to create a meaningful opportunity for reward predicated on the creation of long-term stockholder value.
In February 2023, as part of its annual review of our executive compensation program, and after taking into consideration a competitive market analysis prepared by Compensia and the recommendations of our CEO (except with respect to his own equity award), as well as the factors described in the preceding paragraph, the Compensation Committee granted our Named Executive Officers options to purchase shares of our common stock and PSUs, as follows.

Mr. Krishnan50,00025,000$4,900,261

Ms. Romano20,00010,000$1,960,104 
Mr. Orth(1)
20,00010,000$1,960,104 
(1)Mr. Orth resigned from his position in August 2023 and all of the equity awards granted to him in 2023 were forfeited.

The PSUs granted to our Named Executive Officers on February 28, 2023 could be earned in full or in part upon the achievement during the year ending December 31, 2023, of some or all of the performance criteria that were weighted and approved the Compensation Committee. The performance criteria included specific commercial and regulatory targets concerning VYJUVEK/B-VEC and the commercial launch of VYJUVEK in the United States. We do not disclose the specific 2023 PSU performance criteria due to commercial sensitivity and competitive concerns. The Compensation Committee purposely set the performance criteria at challenging levels. To the extent that some or all of the performance criteria were not achieved during the year ending December 31, 2023, the corresponding amount of PSUs would have been forfeited. The 2023 PSU performance criteria were achieved and, accordingly, one-half of the PSUs granted in 2023 vested on February 28, 2024, the first anniversary of the grant date, and the other one-half of the PSUs granted in 2023 will vest on February 28, 2025, the second anniversary of the grant date, subject to continued employment by the Named Executive Officer through each applicable vesting date.
The options granted to our Named Executive Officers to purchase shares of our Common Stock vest (and become exercisable) over a four-year period, with 25% vesting each year and the first annual vesting date occurring on February 28, 2024. The vesting of the options is contingent on the Named Executive Officer’s continued employment with or service to us through each applicable vesting date.
The equity awards granted to our Named Executive Officers during 2023 are set forth in the “Summary Compensation Table” and the “Grants of Plan-Based Awards Table” below.
Health and Welfare Benefits
Our Named Executive Officers are eligible to participate in the same employee benefit plans, and on the same terms and conditions, as all other full-time, salaried U.S. employees. These benefits include medical, dental, and vision insurance, an employee assistance program, health and dependent care flexible spending accounts, basic life insurance, accidental death and dismemberment insurance, short-term and long-term disability insurance, and commuter benefits.
We also maintain a Section 401(k) retirement plan (the “Section 401(k) Plan”) that provides eligible employees, including our Named Executive Officers, with an opportunity to save for retirement on a tax-advantaged basis. Eligible employees are able to participate in the Section 401(k) Plan as of the first day of the month following the date they meet the plan’s eligibility requirements. Participants are able to defer up to 100% of their eligible compensation subject to applicable annual limits under the Internal Revenue Code (the “Code”). Currently, we match up to 100% of a participant’s first 3% and up to 50% of the next 2% of their eligible contributions to the Section 401(k) Plan. All participants’ interests in their contributions and the Company’s matching contributions to the Section 401(k) Plan are 100% vested when contributed.
38


We design our employee benefits programs to be affordable and competitive in relation to the market as well as compliant with applicable laws and practices. We adjust our employee benefits programs as needed based upon regular monitoring of applicable laws and practices and the competitive market.
Perquisites and Other Personal Benefits
Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not generally provide perquisites or other personal benefits to our Named Executive Officers except as generally made available to our employees or in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make him or her more efficient and effective, and for recruitment and retention purposes. During 2023, our Named Executive Officers did not receive perquisites or other personal benefits that were, in the aggregate, greater than $10,000 per individual, except for reimbursement of up to $10,000 per month for our CEO’s and Ms. Krishnan’s living expenses in connection with working at our corporate headquarters in Pittsburgh, Pennsylvania and matching contributions for the Section 401(k) Plan.
In the future, we may provide perquisites or other personal benefits in limited circumstances, such as those described in the preceding paragraph. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by the Compensation Committee.
Executive Officer Employment Agreements
We have entered into written employment agreements with each of our Named Executive Officers. Each of these agreements was approved by our Board and/or the Compensation Committee. We believe that these arrangements were necessary to secure the continued service of these individuals in a highly competitive job market.
Each of these employment agreements does not have a specific term, provides for “at will” employment (meaning that either we or the Named Executive Officer may terminate the employment relationship at any time) and generally sets forth the Named Executive Officer’s initial base salary, target performance-based annual cash bonus opportunity, eligibility to receive equity awards as determined in the discretion of our Board or authorized committee of the Board, and eligibility to participate in our employee benefit plans and programs in effect for similarly situated employees. In addition, each Named Executive Officer agrees to execute and be bound by our Proprietary Information and Invention Assignment Agreement and to comply with non-disclosure and non-competition covenants contained in the employment agreement.
For detailed descriptions of the employment agreements with our Named Executive Officers, see “Employment Agreements” below.
Post-Employment Compensation
Pursuant to her employment agreement, in the event that we terminate Ms. Romano’s employment for any reason other than for cause, we will pay her an amount equal to four weeks of her then-current base salary, which payment may, at our request, be conditioned upon her execution of a usual and customary general release of claims in our favor.
Pursuant to his employment agreement, in the event that we terminated Mr. Orth’s employment for any reason other than for cause, we will pay him an amount equal to six months of his then-current base salary, which payment may, at our request, be conditioned upon his execution of a usual and customary general release of claims in our favor. Mr. Orth resigned from his position in August 2023 and was not entitled to and did not receive any severance or other benefits under his employment agreement or otherwise.
Other Compensation Policies
Prohibition of Hedging and Pledging of Securities
Under our Insider Trading Policy, our employees, including officers, and the members of our Board of Directors are prohibited from engaging in any of the following activities involving our common stock, except with the prior written consent of our Corporate Compliance Officer or our Board of Directors:
•    short sales (for purposes of our Insider Trading Policy, “short sales” means any transaction in which a person may benefit from a decline in the market price of our common stock);
39


•    buying or selling puts or calls;
•    trading in options (other than those granted by us);
•    engaging in derivative transactions relating to our securities (for example, exchanged traded options, hedging transactions, etc.); and
•    making or maintaining purchases of our securities on margin, including pledging our securities to secure a loan or other obligation.
Clawback Policy
Upon the recommendation of the Compensation Committee, on August 4, 2023, the Board adopted an Executive Incentive Compensation Recoupment Policy (the “Clawback Policy”), in accordance with the NASDAQ listing standards and Rule 10D-1 under the Exchange Act, which Clawback Policy applies to our current and former executive officers. Under the Clawback Policy, we are required to recoup the amount of any erroneously awarded incentive-based compensation (as defined in the Clawback Policy) on a pre-tax basis within a specified lookback period in the event of any accounting Restatement (as defined in the Clawback Policy), subject to limited impracticability exceptions. Covered accounting Restatements include both a restatement of our financial statements to correct an error that is material to previously issued financial statements or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The amount required to be recovered is the excess of the amount of incentive-based compensation received over the amount that otherwise would have been received had it been determined based on the information in an accounting Restatement. The Clawback Policy is overseen and administered by the Compensation Committee. The full text of the Clawback Policy was included as Exhibit 97.1 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 26, 2024.
Tax and Accounting Considerations
The Compensation Committee takes the applicable tax and accounting requirements into consideration in designing and overseeing our executive compensation program.  
Deductibility of Executive Compensation
Under Section 162(m) of the Code, compensation paid to our covered executive officers (including our CEO, Chief Accounting Officer, and other Named Executive Officers), and except for certain grandfathered arrangements and certain compensation paid pursuant to a compensation plan in existence before the effective date of our initial public offering, will not be deductible to the extent it exceeds $1 million. In 2023, the Compensation Committee considered the potential future effects of Section 162(m) when determining Named Executive Officer compensation and the Compensation Committee is expected to consider the potential future effects of Section 162(m) when determining future Named Executive Officer compensation.
Accounting for Stock-Based Compensation
The Compensation Committee takes accounting considerations into account in designing compensation plans and arrangements for our executive officers and other employees. Chief among these is ASC Topic 718, the standard which governs the accounting treatment of certain stock-based compensation. Among other things, ASC Topic 718 requires us to record a compensation expense in our income statement for all equity awards granted to our executive officers and other employees. This compensation expense is based on the grant date “fair value” of the equity award and, in most cases, will be recognized ratably over the award’s requisite service period (which, generally, will correspond to the award’s vesting schedule). This compensation expense is also reported in the compensation tables below, even though recipients may never realize any value from their equity awards.
Taxation of “Parachute” Payments
Sections 280G and 4999 of the Code provide that officers and directors who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of the Company that exceeds certain prescribed limits, and that the Company (or a successor) may forfeit a deduction on the amounts subject to this additional tax. We have not
40


agreed to provide any Named Executive Officer, with a “gross-up” or other reimbursement payment for any tax liability that the executive officer might owe as a result of the application of Sections 280G or 4999 of the Code.
Compensation Committee Report
The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis included in this Proxy Statement with management and, based on such review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be incorporated by reference in the Company’s Annual Report on Form 10-K for fiscal year 2023 and included in this Proxy Statement.

CEO Pay Ratio
Our compensation and benefits philosophy and the overall structure of our compensation and benefit programs are broadly similar across the organization to encourage and reward all employees who contribute to our success. We strive to ensure the pay of each of our employees reflects the level of their job impact and responsibilities and is competitive within our peer group. Compensation rates are benchmarked and are generally set to be market-competitive. Our ongoing commitment to pay equity is critical to our success in supporting a diverse workforce with opportunities for all employees to grow, develop and contribute.
Under rules adopted pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we are required to calculate and disclose the total compensation paid to our median paid employee, as well as the ratio of the total compensation paid to the median employee as compared to the total compensation paid to our Chief Executive Officer (the “CEO Pay Ratio”). The paragraphs that follow describe our methodology and the resulting CEO Pay Ratio.
We identified the median employee using our employee population on December 31, 2023 (including all employees (except our CEO), whether employed on a full-time, part-time, or temporary basis). We identified the median employee using the employee’s annual total compensation in accordance with the requirements of the Summary Compensation table as of December 31, 2023 for all active employees as of that date. We did not perform adjustments to the compensation paid to part-time employees to calculate what they would have been paid on a full-time basis. In identifying the median employee, we did not exclude workers in non-U.S. countries and did not make any cost-of-living adjustments.
Our median employee compensation for 2023 as calculated using Summary Compensation Table requirements was $216,129. Our Chief Executive Officer’s 2023 compensation as reported in the Summary Compensation Table was $6,223,894. Therefore, our CEO Pay Ratio is approximately 28.8 to 1.
This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither the Compensation Committee nor management of the Company used the CEO Pay Ratio measure in making compensation decisions.

Pay Versus Performance
We are providing the following information about the relationship between executive compensation actually paid and certain financial performance of the Company. For further information concerning the Company’s variable pay-for-performance philosophy and how the Company aligns executive compensation with the Company’s performance, refer to “Compensation of Named Executive Officers – Compensation Discussion and Analysis.” The FDA approved our first product, VYJUVEK, in May 2023, and we subsequently initiated our U.S. commercial launch of VYJUVEK and booked our first revenue from product sales in mid-2023. Therefore, 2023 was an inflection point for the Company as we transitioned from a company with a research and development focus to a commercial company. When the 2023 incentive compensation program was approved, we were a clinical stage company and, therefore, we focused our incentive compensation programs and practices for 2023 on operational and strategic rather than financial measures of performance. Accordingly, we have not included a “Company-Selected Measure” in the Pay Versus Performance table below or a list of financial performance measures as we did not use any financial performance measures to link 2023 compensation actually paid to Company performance.

The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments are as follows:

(3)The dollar amounts reported in column (d) represent the average of the amounts reported for the Company’s named executive officers (“NEOs”) as a group (excluding Mr. Krishnan, who has served as our CEO since the Company’s inception) in the “Total” column of the Summary Compensation Table in each applicable year. The names of each of the NEOs (excluding Mr. Krishnan) included for purposes of calculating the average amounts in each applicable year are as follows: (i) for 2023, 2022, and 2021, Suma M. Krishnan, Kathryn A. Romano and Andrew C. Orth; and (ii) for 2020, Suma M. Krishnan and Kathryn A. Romano.
(4)    The dollar amounts reported in column (e) represent the average amount of “compensation actually paid” to the NEOs as a group (excluding Mr. Krishnan), as computed in accordance with Item 402(v) of Regulation
S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding Mr. Krishnan) during the applicable year. Average Compensation Actually Paid to Non-PEO NEOs for 2023 is less than the reported Average Summary Compensation for Non-PEO NEOs due to Mr. Orth’s resignation in August 2023. His resignation resulted in forfeiture and cancellation of all of his unvested equity awards which resulted in a negative equity award value and decrease in Average Compensation Actually Paid. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding Mr. Krishnan) for each year to determine the compensation actually paid, using the same methodology described above in Note 2:

(5)    Cumulative Total Shareholder Return (“TSR”) is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period. For each of the periods presented, the Company did not pay any dividends.
(6)    Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: NASDAQ Biotech Index.
(7)    Other than 2023, the Company reported net losses for the applicable years as it was a clinical stage biotechnology company without any commercialized products.
Financial Performance Measures
As described in greater detail in “Compensation of Named Executive Officers – Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. The metrics that the Company uses for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our stockholders. At the start of 2023 and when the performance measures for the NEOs 2023 incentive compensation were approved, we were a clinical stage biotechnology company without any revenue. Accordingly, financial performance measures were not used by the Company to link executive compensation actually paid to the Company’s NEOs to the Company’s performance. Therefore, the Company has not included a Company-Selected Measure or any financial performance measures in the Pay versus Performance disclosure.
Analysis of the Information Presented in the Pay Versus Performance Table
As described in more detail in the section “Compensation of Named Executive Officers – Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. While the Company utilizes several non-financial performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s non-financial performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.
Compensation Actually Paid and Cumulative TSR
The following graph demonstrates the amount of compensation actually paid (CAP) to Mr. Krishnan and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Krishnan) and
48


the Company’s cumulative TSR over the four years presented in the table. Cumulative TSR is calculated using a $100 initial investment on January 1, 2020.
https://cdn.kscope.io/8cbc01e1582254831460bbe13f59b4f1-Compensation Actually Paid Table.jpg
Compensation Actually Paid and Net Income (Loss)
As a clinical stage biotechnology company without any commercialized products during 2020, 2021, and 2022, the Company reported net losses for such years. The FDA approved our first product, VYJUVEK, in May 2023, and we subsequently initiated our U.S. commercial launch of VYJUVEK and booked our first revenue from product sales in mid-2023, and we reported net income for 2023. The Company did not use financial performance measures to link executive compensation actually paid to the Company’s NEOs to Company performance during the applicable years in the Pay Versus Performance Table. As a result, the amount of compensation actually paid to Mr. Krishnan and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Krishnan) does not align with the Company’s Net Income (Loss) over the four years presented in the table.
Cumulative TSR of the Company and Cumulative TSR of the Peer Group
As demonstrated by the following graph, the Company’s cumulative TSR over the four-year period presented in the table was 124.1%, while the cumulative TSR of the peer group presented for this purpose, the NASDAQ Biotech Index, was 15.2%. TSR is calculated using a $100 initial investment on January 1, 2020. The Company’s cumulative TSR outperformed the NASDAQ Biotech Index as of the end of the four years presented in the table. For more information regarding the Company’s performance and the companies that the Compensation Committee considers when determining executive compensation, refer to “Compensation of Named Executive Officers – Compensation Discussion and Analysis.”

REPORT OF THE AUDIT COMMITTEE
The Audit Committee is currently composed of Messrs. Rossi, Janney and Gangolli, and Dr. Sutherland, with Mr. Rossi serving as its chairperson. The members of the Audit Committee are appointed by and serve at the discretion of the Board.
One of the principal purposes of the Audit Committee is to assist the Board in the oversight of the integrity of the Company’s financial statements. The Company’s management team has the primary responsibility for the financial statements and the reporting process, including the system of internal controls and disclosure controls and procedures. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited financial statements in the Annual Report on Form 10-K for the fiscal year ended December 31, 2023 with our management.
The Audit Committee also is responsible for assisting the Board in the oversight of the qualification, independence and performance of the Company’s independent registered public accountants. The Audit Committee reviewed with the independent registered public accountants, who are responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards and those matters required to be discussed pursuant to the applicable standards of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC.
The Audit Committee has received both the written disclosures and the letter from KPMG required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence and has discussed with KPMG its independence. In addition, the Audit Committee has considered whether the provision of non-audit services, and the fees charged for such non-audit services, by KPMG are compatible with maintaining the independence of KPMG from management and the Company.
Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the Company’s audited financial statements for 2023 be included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2023 for filing with the SEC.
Respectfully submitted,
The Audit Committee of the Board of Directors
Dino A. Rossi (Chairman)
Julian S. Gangolli
Daniel S. Janney
E. Rand Sutherland
The Audit Committee Report above does not constitute “soliciting material” and will not be deemed “filed” or incorporated by reference into any of our filings under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent that the Company specifically incorporates the Audit Committee Report by reference therein.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
Related Party Transaction Policy
We have adopted a written related party transactions policy that provides that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of our common stock and any members of the immediate family of the foregoing persons, are not permitted to enter into a material related-person transaction with us without the review and approval of our Audit Committee, or a committee composed solely of independent directors in the event it is inappropriate for our Audit Committee to review such transaction due to a conflict of interest. The policy provides that any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of our common stock or with any of their immediate family members or affiliates, in which the amount involved exceeds $120,000 will be presented to our Audit Committee for review, consideration and approval. In approving or rejecting any such proposal, we expect that our Audit Committee will consider the relevant facts and circumstances available and deemed relevant to the Audit Committee, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.
Related Party Transactions
Indemnification of Officers and Directors
Our charter and bylaws provide for certain indemnification rights for our directors and officers and we entered into an indemnification agreement with each of our executive officers and directors, providing for procedures for indemnification and advancement by us of certain expenses and costs relating to claims, suits or proceedings arising from their service to us or, at our request, service to other entities, as officers or directors, or in certain other capacities, to the maximum extent permitted by Delaware law.

OTHER MATTERS
Other Matters to Come Before the 2024 Annual Meeting
No other matters are to be presented for action at the Annual Meeting other than as set forth in this Proxy Statement. If other matters properly come before the meeting, however, the persons named in the accompanying proxy card will vote all proxies solicited by this Proxy Statement as recommended by the Board, or, if no such recommendation is given, in their own discretion.
Stockholders Proposals and Nominations for the 2025 Annual Meeting
Any stockholder proposal pursuant to Rule 14a-8 of the rules promulgated under the Exchange Act, to be considered for inclusion in our proxy materials for the 2025 annual meeting of stockholders must be received at our principal executive offices no later than December 5, 2024.
In addition, any stockholder who wishes to propose a nominee to the Board or propose any other business to be considered by the stockholders (other than a stockholder proposal included in our proxy materials pursuant to Rule 14a-8 of the rules promulgated under the Exchange Act) must comply with the advance notice provisions and other requirements of Section 2.9 of our bylaws, which are on file with the SEC and may be obtained from our Corporate Secretary upon request. These notice provisions require that nominations of persons for election to the Board and the proposal of business to be considered at the 2025 annual meeting of stockholders must be received no earlier than December 5, 2024 and no later than January 4, 2025.
Householding of Proxy Materials
The SEC has adopted rules that permit companies and intermediaries (such as banks and brokers) to satisfy the delivery requirements for notices of annual meetings, proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies. This year, a single notice of the annual meeting of stockholders, or copy of the Proxy Statement and annual report, will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your bank or broker that it will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, please notify your bank or broker, and direct your written request to Krystal Biotech, Inc. at 2100 Wharton Street, Suite 701, Pittsburgh, Pennsylvania 15203, Attention: Corporate Secretary, or contact us by telephone at (412) 586-5830. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request householding of their communications should contact their bank or broker.
