A: Our Board is soliciting your proxy to vote at our Annual Meeting, including at any adjournments or postponements of the meeting.

Q: Why did I receive a notice regarding the availability of proxy materials on the Internet?

A: Pursuant to rules adopted by the Securities and Exchange Commission (the "SEC"), we have elected to provide access to our proxy materials over the Internet. Accordingly, we have sent you a Notice because the Board is soliciting your vote at the Annual Meeting, including at any adjournments or postponements of the meeting. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice and may request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice.

Q:Will I receive any other proxy materials by mail?

A:We may send you a proxy card, along with a second Notice, on or after November 1, 2024. In addition, if you wish, we will send you paper copies of our proxy materials, including a proxy card. Instructions on how to request paper copies of the proxy materials can be found in the Notice.

Q: How can I attend the Annual Meeting?

A: The Annual Meeting will be a virtual meeting of stockholders, which will be conducted exclusively by live audio webcast. Participants will receive an Internet link to where the audio webcast will be held once they register for the Annual Meeting. You are entitled to participate in the Annual Meeting only if you were a stockholder of record of the Company as of the close of business on October 25, 2024 (the "Record Date"), or if you hold a valid proxy for the Annual Meeting. No physical meeting will be held.

The online meeting will begin promptly at 10:00 AM. CST, on December 20, 2024. You may attend the Annual Meeting, vote, and submit a question during the Annual Meeting by webcast by first registering at http://www.viewproxy.com/slrx/2024 by 11:59 PM CT on December 17, 2024 . If you hold your shares in an account at a brokerage firm, bank, dealer or other similar organization, you will need to obtain a "legal proxy" from that entity and submit it when you register. On the day of the Annual Meeting, if you have properly registered, you may enter the meeting by clicking on the link provided and entering the password you received via email in your registration confirmations. We encourage you to access the meeting prior to the start time leaving ample time for the check in. To vote at the meeting, (a) if you hold your shares through a broker, bank or other nominee, you will need the control number you receive by email after registering, and (b) if you hold your shares in an account with our transfer agent, you will need the control number that is shown on your Notice of Internet Availability of Proxy Materials or on your proxy card if you elected to receive proxy materials by mail.

Q: Who can vote at the Annual Meeting?

A: Only stockholders of record at the close of business on the Record Date, October 25, 2024, will be entitled to vote at the Annual Meeting. On the Record Date, there were 1,441,157 shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on the close of business on the Record Date, your shares were registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, then you are a stockholder of record. As a stockholder of record, you may vote online during the Annual Meeting, via the Internet, by mail, or by telephone as described below. Giving a proxy will not affect your right to vote during the Annual Meeting. Whether or not you plan to attend the meeting, we urge you to vote promptly to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Nominee

If on the close of business on the Record Date, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in "street name" and the Notice is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct that organization regarding how to vote the shares in your account. Stockholders holding shares through a broker, bank or other nominee should follow the instructions in the materials received from that organization. You are also invited to attend the Annual Meeting. If you wish to attend the Annual Meeting, you must register in advance following the instructions above.

Q: What am I voting on?

A: There are three matters scheduled for a vote:

1.To elect two Class III directors to our Board, each to serve until our 2027 Annual Meeting of Stockholders or until their respective successors are duly elected and qualified.

2.To approve, on a non-binding advisory basis, the compensation paid by us to our named executive officers as disclosed in this proxy statement.

3.To ratify the appointment, by the Audit Committee of the Board, of Ernst & Young LLP as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 2024.

Q: What are the Board's recommendations?

A: Our Board recommends that you vote:

•"FOR" ELECTION OF EACH OF THE NOMINEES FOR CLASS III DIRECTOR;

•"FOR" THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION PAID BY US TO OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT; AND

•"FOR" RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2024.

Q: What if another matter is properly brought before the meeting?

A: The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the proxy holder to vote on those matters in accordance with their best judgment.

Q: How do I vote?

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote during the Annual Meeting, vote by proxy over the telephone, vote by proxy through the Internet or vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote at that time even if you have already voted by proxy.

•Voting via the Internet. To vote through the Internet, go to http://www.AALvote.com/slrx to complete an electronic proxy card. You will be asked to provide the control number from your Notice or proxy card. Your vote must be received by 11:59 PM EST on December 19, 2024. We encourage you to vote via the Internet.

•Voting by mail. To vote using the proxy card, simply complete, sign and date the proxy card that may be delivered to you and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.

•Voting by telephone. To vote over the telephone, dial toll-free 1-866-804-9616, using a touch-tone telephone and follow the recorded instructions. You will be asked to provide the control number from your Notice or proxy card. Your vote must be received by 11:59 PM EST on December 19, 2024 to be counted.

•Voting at the Annual Meeting. To vote at the Annual Meeting, you must join live online using the unique join link provided after registration. The webcast will start at 10:00 AM. CST, with log-in beginning at 9:45 AM CST. You may vote and submit questions while attending the meeting online. You will need the control number included on your Notice or your proxy card (if you received a printed copy of the proxy materials) to vote during the meeting.

Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Nominee

If you are a beneficial owner of shares registered in the name of your broker, bank or other nominee, you should have received a Notice containing voting instructions from that organization rather than from the Company. Simply follow the voting instructions in the Notice to ensure that your vote is counted. To vote at the Annual Meeting, you must obtain a valid proxy from your broker, bank or other nominee, register to attend the Annual Meeting following the instructions above and vote in accordance with the procedures described above. Follow the instructions set forth on the Notice or from your broker, bank or other nominee or contact that organization to request a voting instruction form.

We provide telephone and Internet proxy voting to allow you to vote your shares telephonically or online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your telephone or Internet access, such as usage charges from Internet access providers and telephone companies.

Q: How many votes do I have?

A: On each matter to be voted upon, you have one vote for each share of common stock you own as of the close of business on the Record Date, which is October 25, 2024.

Q: What happens if I do not vote?

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the Internet, or at the Annual Meeting, your shares will not be voted.

Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Nominee

If you are a beneficial owner of shares held in "street name" and do not instruct your broker, bank, or other nominee how to vote your shares, the question of whether that organization will still be able to vote your shares depends on whether the particular proposal is deemed to be "routine" under the rules of the New York Stock Exchange (also applicable to companies listed on the Nasdaq Capital Market ("Nasdaq")). Brokers, banks and other nominees can use their discretion to vote "uninstructed" shares only with respect to matters that are considered to be "routine." They may not vote your shares with respect to matters that are considered "non-routine" and for these matters your shares will be left unvoted. "Non-routine" matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation), approval of equity incentive plans, and certain corporate governance proposals, even if management-supported. Proposal 3 (ratifying the appointment of our independent registered public accounting firm) is considered a routine matter under applicable NYSE rules. Proposal 1 (election of directors) and Proposal 2 (advisory vote on the approval of named executive officer compensation) are each considered a "non-routine" item for which brokers and nominees do not have discretionary voting power. If your broker, bank or other nominee returns a proxy card but does not vote your shares, this results in a "broker non-vote." Broker non-votes will be counted as present for the purpose of determining a quorum. However, as brokers, banks or other nominees do not have discretionary authority to vote on Proposals 1 and 2, broker non-votes will not be counted for the purpose of determining the number of shares entitled to vote on such proposals. Accordingly, your broker, bank or other nominee may not vote your shares on Proposals 1 or 2 without your instructions but may vote your shares on Proposal 3. If you are a beneficial owner of shares held in "street name" you must provide voting instructions to your broker, bank or other nominee by the deadline provided in the materials you receive from such organization in order to ensure your shares are voted in the way you would prefer.

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

A: If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, "FOR" the election of each of the nominees for director, "FOR" the approval, on a non-binding advisory basis, of the named executive officer compensation, and "FOR" the ratification of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024. If any other matter is properly presented at the meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

Q: Who am I being asked to appoint as proxy holders and what does it mean?

A: Our Board asks you to appoint our President, Chief Executive Officer and director, David J. Arthur, and our Executive Vice President of Finance and Chief Financial Officer, Mark J. Rosenblum, as your proxy holders to vote your shares at the Annual Meeting. You make this appointment when you vote.

If appointed by you, the proxy holders will vote your shares as you direct on the matters described in this proxy statement. In the absence of your direction, they will vote your shares as recommended by our Board.

Unless you otherwise indicate when you vote, you also authorize your proxy holders to vote your shares on any matters not known by our Board at the time this proxy statement was printed and which, under our amended and restated bylaws (the "Bylaws"), may be properly presented for action at the Annual Meeting.

Q:Who is paying for this proxy solicitation?

A: We will pay the entire cost of the solicitation of proxies for the Annual Meeting. This includes preparation, assembly, printing, and mailing of the Notice, this proxy statement and any other information we send to stockholders. We have engaged Alliance Advisors, LLC to assist in the solicitation of proxies and provide related advice and information support, for a services fee and the reimbursement of customary disbursements, which are not expected to exceed $85,900 in the aggregate. In addition, we may supplement our efforts to solicit your proxy in the following ways:

•We may contact you using the telephone or electronic communication;

•Our directors, officers or other regular employees may contact you personally; and

•Alliance Advisors, LLC or any other third parties we may hire as agents for the sole purpose of contacting you regarding your proxy, may contact you.

Q:What does it mean if I receive more than one Notice?

A:If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each of the Notices to ensure that all of your shares are voted.

Q:I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

A:We have adopted a procedure called "householding," which the SEC has approved. Under this procedure, we deliver a single copy of the Notice and, if applicable, our proxy materials to multiple stockholders who share the same address unless we have received contrary instructions from one or more of such stockholders. This procedure reduces our printing costs, mailing costs, and fees. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will promptly deliver a separate copy of the Notice and, if applicable, our proxy materials to any stockholder at a shared address to which we delivered a single copy of any of these materials. To receive a separate copy, or, if a stockholder is receiving multiple copies, to request that we only send a single copy of the Notice and, if applicable, our proxy materials, such stockholder may contact us at the following address:

Salarius Pharmaceuticals, Inc.

Attention: Investor Relations

2450 Holcombe Blvd

Suite X

Houston, TX 77021

[email protected]

Street name stockholders may contact their broker, bank, or other nominee to request information about householding.

Q: Can I change or revoke my vote after submitting my proxy?

A:Stockholder of Record: Shares Registered in Your Name

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

•You may submit a properly completed proxy card with a later date.

•You may grant a subsequent proxy by telephone or through the Internet.

•You may send a timely written notice that you are revoking your proxy to our Secretary.

•You may attend the Annual Meeting via the live webcast and vote. Attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically so request.

We count your most current proxy card or telephone or Internet proxy.

Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Nominee

A: Stockholders holding shares through a broker, bank or other nominee should follow the instructions for revocation received from that organization.

Q:How are Abstentions, Withheld and Broker Non-Votes counted?

A: For Proposal 1, the election of directors, you may vote "FOR" each of the Class III nominees, vote "AGAINST" any or all of the Class III nominees or "ABSTAIN" with respect to any or all of the Class III nominees. An abstention has the same effect as a vote "AGAINST" a director nominee in Proposal 1. Broker non-votes will have no effect.

For Proposal 2, the approval, on a non-binding advisory basis, of the compensation of our named executive officers, you may vote "FOR," vote "AGAINST" or "ABSTAIN." An abstention has the same effect as a vote "AGAINST" Proposal 2. Broker non-votes will have no effect.

For Proposal 3, the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024, you may vote "FOR", vote "AGAINST" or "ABSTAIN". An abstention has the same effect as a vote "AGAINST" Proposal 3. Broker non-votes will have no effect.

Q: How many votes are needed to approve each proposal?

A:For Proposal 1, the election of the directors, a nominee receiving the affirmative vote of a majority of the voting power of the capital stock entitled to vote and present in person or represented by proxy at the Annual Meeting will be elected. Further, if the majority of the votes cast for a director are marked "AGAINST" or "ABSTAIN" then notwithstanding the valid election of such director, the Bylaws stipulate that such director will voluntarily tender his or her resignation for consideration by our Nominating and Corporate Governance Committee. Our Board will determine whether to accept the resignation of such director, taking into account the recommendation of the Nominating and Corporate Governance Committee.

For Proposal 2, the approval, on a non-binding advisory basis, of the compensation of our named executive officers, requires the affirmative vote of a majority of the voting power of the capital stock entitled to vote and present in person or represented by proxy at the Annual Meeting.

For Proposal 3, the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024, requires the affirmative vote of a majority of the voting power of the capital stock entitled to vote and present in person or represented by proxy at the Annual Meeting.

Q: What is the quorum requirement?

A: A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least 34% of the outstanding shares entitled to vote are present at the meeting or represented by proxy. As of the close of business on the Record Date, there were 1,441,157 shares outstanding and entitled to vote.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank, or other nominee) or if you vote by telephone, over the Internet or at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum either any officer entitled to preside at such meeting or the holders of a majority of the shares present at the meeting or represented by proxy may adjourn the meeting from time to time until a quorum shall be present or represented.

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

A: Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

Q: Who can help answer my other questions?

A: If you have more questions about the proposals or voting, you should contact Alliance Advisors, LLC who is assisting us with the proxy solicitation.

DIRECTORS AND EXECUTIVE OFFICERS

Directors

Our Board consists of seven (7) directors which are divided into three classes: Class I, Class II, and Class III. Each class has a three-year term:

Arrangements between Officers and Directors

To our knowledge, there is no arrangement or understanding between any of our officers and any other person, including directors, pursuant to which the officer was selected to serve as an officer.

CORPORATE GOVERNANCE

Board of Directors

Our business and affairs are organized under the direction of the Board, which currently consists of seven members. Dr. McVicar currently serves as the Chair of our Board. The primary responsibilities of our Board are to provide oversight, strategic guidance, counseling, and direction to our management. Our Board meets on a regular basis and additionally as required.

Director Independence

The Nasdaq Listing Rules generally require that a majority of the members of a listed company's board of directors must qualify as "independent" as affirmatively determined by its board of directors. The Board of Directors consults with the Company's counsel to ensure that the Board of Directors' determinations are consistent with relevant securities 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.

Our Board of Directors has undertaken a review of its composition, the composition of its committees and the independence of each director and director nominee. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board of Directors has determined that six of our current directors, including Mr. McVicar, Ms. Burleson, Mr. Hanish, Dr. Lammers, Dr. McCreedy and Mr. Lieber, are "independent" as that term is defined under the applicable rules and regulations of the SEC and the listing requirements of Nasdaq.

Our Board of Directors has determined that Mr. Arthur, Chief Executive Officer of the Company in his role as a part-time consultant, is not independent under the applicable rules and regulations of the SEC and Nasdaq Listing Rules. In making these determinations, our Board of Directors considered the current and prior relationships that each non-employee director has with us and all other facts and circumstances our Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

Board Leadership Structure

Our Bylaws provide that if a chair of the Board of Directors is appointed, that person will preside at all meetings of the Board of Directors at which they are present. Currently, the position of chair of our Board of Directors is filled by Dr. McVicar.

The Board of Directors periodically reviews its leadership structure and developments in the area of corporate governance to ensure that this approach continues to strike the appropriate balance for the Company and our stockholders.

Ant-Hedging Policy; Policy on Pledging

We have an insider trading policy that sets forth guidelines and restrictions applicable to transactions involving our stock by our directors, officers and employees. Among other things, this policy prohibits our directors, officers and employees from engaging in purchases or sales of puts, calls, options or other derivative securities based on the Company's securities. These hedging transactions are prohibited because they would allow directors, officers and employees to continue to own the covered securities, but without the full risks and rewards of ownership. When that occurs, their interests and the interests of the Company and its stockholders may be misaligned and may signal a message to the trading market that may not be in the best interests of the Company and its stockholders at the time it is conveyed. The insider trading policy also prohibits directors and officers from engaging in short sales of the Company's securities.

Role of our Board of Directors in Risk Oversight

One of the key functions of the Board is informed oversight of our risk management process. Our Board does not have a standing risk management committee, but rather administers this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that address risks inherent in their

respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure and 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. Our Compensation Committee also assesses and monitors whether our compensation plans, policies, and programs comply with applicable legal and regulatory requirements.

Committees of the Board

Our Board has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. Our Board has adopted a charter for each of these committees, each of which complies with the applicable requirements of current Nasdaq rules. We intend to comply with future requirements to the extent they are applicable to us. Copies of the charters for each committee are available on the investor relations portion of our website at http://investors.salariuspharma.com/corporate-governance/highlights.

Audit Committee

The Audit Committee currently consists of Ms. Burleson, Mr. Hanish, and Mr. Lieber. Mr. Hanish serves as the chair of our Audit Committee.

In making this determination, the Board of Directors has considered Mr. Hanish's business background and previous experience. Both our independent registered public accounting firm and management periodically meet with the Audit Committee.

We intend to comply with future requirements to the extent they become applicable to us.

Board and Committee Meeting Attendance

In 2023, our Board held seven meetings. Each of our directors attended at least 75% of the aggregate number of meetings of our Board and meetings of any committee of which he or she was a member, which were held during the time in which he or she was a director or a committee member, as applicable. Our non-management directors meet in regularly scheduled sessions without the presence of management in executive sessions. Our Audit Committee held four meetings, our Nominating and Corporate Governance Committee held one meeting, and our Compensation Committee held two meetings in 2023. Directors are encouraged to attend our annual meeting of stockholders, either via webcast or telephonically.

Code of Ethics

The Board has adopted a Code of Business Conduct and Ethics (the "Code of Conduct") applicable to all of our employees, executive officers, and directors. The Code of Conduct is available on our website at www.salariuspharma.com. Information contained on or accessible through our website is not a part of this Proxy Statement, and the inclusion of our website address in this Proxy Statement is an inactive textual reference only. The Nominating and Corporate Governance Committee is responsible for overseeing the Code of Conduct and must approve any waivers of the Code of Conduct for employees, executive officers, and directors. We expect that any amendments to the Code of Conduct, or any waivers of its requirements, will be disclosed on our website.

We also implemented whistleblower procedures that establish formal protocols for receiving and handling complaints from employees. Any concerns regarding accounting or auditing matters reported under these procedures will be communicated promptly to our Audit Committee.

Director Nominations

Our Board nominates directors for election at each annual meeting of stockholders and elects new directors to fill vacancies when they arise. Our Nominating and Corporate Governance Committee has the responsibility to identify, evaluate, recruit, and recommend qualified candidates to our Board for nomination or election.

Director Criteria. Our Nominating and Corporate Governance Committee has a policy regarding consideration of director candidates recommended by stockholders. Our Nominating and Corporate Governance Committee reviews suggestions for director candidates recommended by stockholders and considers such candidates for recommendation based upon an appropriate balance of knowledge, experience, and capability. In addition to considering an appropriate balance of knowledge, experience, and capability, our Board has as an objective that its membership be composed of experienced and dedicated individuals with diverse backgrounds, perspectives, skills, genders, and ethnicities. Our Nominating and Corporate Governance Committee selects director candidates based on the candidate possessing relevant market and technological expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment, diversity, potential for long-term contribution to the Company's business, and having the commitment and vision to rigorously represent the long-term interests of the Company's stockholders. Our Nominating and Corporate Governance Committee believes it is appropriate for a majority of the members of our Board to meet the definition of "independent director" under the Nasdaq rules. Our Nominating and Corporate Governance Committee also believes it appropriate for our Chief Executive Officer to participate as a member of our Board.

Prior to each annual meeting of stockholders, our Nominating and Corporate Governance Committee first identifies nominees by reviewing the current directors whose terms expire at the annual meeting of stockholders and who are

willing to continue in service. These candidates are evaluated based on the criteria described above, including as demonstrated by the candidate's prior service as a director, and the needs of our Board, with respect to the particular talents and experience of its directors. If a director does not wish to continue in service, the Nominating and Corporate Governance Committee determines not to nominate the director, or a vacancy is created on our Board as a result of a resignation, an increase in the size of our Board or other event, the Nominating and Corporate Governance Committee will consider various candidates for Board membership, including those suggested by members of the Nominating and Corporate Governance Committee, by other members of our Board, by any executive search firm engaged by the Nominating and Corporate Governance Committee, and by stockholders. A stockholder who wishes to suggest a prospective nominee for our Board should notify our Secretary, any member of the Nominating and Corporate Governance Committee, or the persons referenced below in "Communications with our Board of Directors" in writing with any supporting material the stockholder considers appropriate.

Stockholder Nominees. In addition, our Bylaws contain provisions that address the process by which a stockholder may nominate an individual to stand for election to our Board at our annual meeting of stockholders. In order to nominate a candidate for director, a stockholder must give timely notice in writing to our Secretary and otherwise comply with the provisions of our Bylaws. To be timely, our Bylaws provide that we must have received the stockholder's notice not more than one hundred twenty (120) days nor less than ninety (90) days prior to the anniversary of the previous year's proxy statement provided in connection with the previous year's annual meeting of stockholdersprovided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is called for a date more than thirty (30) days before or after the anniversary date of the previous year's annual meeting, notice by the stockholder must be received by our Secretary not later than the close of business on the later of (A) the ninetieth (90th) day prior to such annual meeting and (B) the tenth (10th) day following the day on which public announcement of the date of such meeting is first made. Information required by our Bylaws to be in the notice include the name and contact information for the candidate and the person making the nomination and other information about the nominee that must be disclosed in proxy solicitations under Section 14 of the Exchange Act and the related rules and regulations under that section.

You can obtain a copy of our Bylaws by writing to the Secretary at this address.

Meetings of Our Independent Directors and Communications with our Board of Directors

During meetings of the Board, the independent directors meet regularly in an executive session without management or management directors present. The purpose of these executive sessions is to promote open and candid discussion among the non-management directors.Our Board recommends that stockholders and other interested parties initiate communications with our Board, the independent directors, the Chair, or any committee of our Board in writing to the attention of our Secretary, Salarius Pharmaceuticals, Inc., 2450 Holcombe Blvd. Suite X, Houston, TX 77021.

Compensation Arrangements

Our non-employee director compensation is comprised of cash compensation and equity compensation. Further, we reimburse all of our non-employee directors for their reasonable expenses incurred in attending meetings of our Board and committees of the Board.

Generally, our Board believes that the level of director compensation should be based on time spent carrying out Board and committee responsibilities and be competitive with comparable companies.

The Board makes changes in its director compensation practices only upon the recommendation of the Compensation Committee, and discussion and approval by the Board.

Our Board, following the Compensation Committee's recommendation, has approved the compensation of our non-employee directors, as described below. The compensation of our non-employee directors remains the same as it was in 2023.

Narrative Disclosure to Summary Compensation Table

In the process of determining compensation for our named executive officers, the Compensation Committee considers the current financial position of the Company, the strategic goals of the Company, and the performance of each of our named executive officers. In addition, from time to time, the Compensation Committee considers the various components (described below) of our compensation program for executives in relation to compensation paid by other public companies, compensation data, their historical review of all executive officer compensation, and recommendations from our Chief Executive Officer (other than for his own salary). The Compensation Committee has the sole authority to select, compensate and terminate its external advisors.

The Compensation Committee utilizes the following components of compensation (described further below) to strike an appropriate balance between promoting sustainable and excellent performance and discouraging any excessive risk-taking behavior:

•Base Salary;

•Non-equity incentive plan compensation;

•Annual long-term equity compensation;

•Personal benefits and perquisites; and

•Acceleration and severance agreements tied to changes in control of the Company.

Base Salaries

Our named executive officers receive base salaries as set forth in their respective employment or consulting agreements. Each named executive officer is eligible for annual raises subject to review and approval of the Compensation Committee. There were no salary raises in 2023. Mr. Arthur's base salary was $500,000 for 2023. Mr. Rosenblum's base salary was $330,000 for 2023.

Non-Equity Incentive Plan Compensation

Target bonuses are reviewed annually and established as a percentage of the executives' base salaries, generally based upon seniority of the officer and targeted at or near the median of the peer group (with reference to our corporate compensation philosophy) and relevant survey data. Each year, the Compensation Committee establishes corporate and individual objectives and respective target percentages, taking into account recommendations from our Chief Executive Officer as it relates to executive positions other than the Chief Executive Officer's compensation. Our Chief Executive Officer's target bonus is set by the Compensation Committee to align entirely with our overall corporate objectives. At the end of each fiscal year-end, our Chief Executive Officer provides the Compensation Committee with a written evaluation showing actual performance as compared to corporate and/or individual objectives, and the Compensation Committee uses that information, along with the overall corporate performance, to determine what percentage of each executive's bonus target will be paid out as a bonus for that year. Overall, the Compensation Committee seeks to establish the corporate and individual functional goals to be highly challenging yet attainable.

Mr. Arthur's and Mr. Rosenblum's target bonus' for both 2023 and 2022 as a percentage of base salary was 50% and 35% respectively. Neither named executive officer received a bonus for our 2023 fiscal year.

Long-Term Equity Compensation

We designed our long-term equity grant program to further align the interests of our executives with those of our stockholders and to reward the executives' longer-term performance. Historically, the Compensation Committee has granted stock options, although from time-to-time, to further increase the emphasis on compensation tied to performance, the Compensation Committee may grant other equity awards as allowed by the Salarius Pharmaceuticals 2015 Equity Incentive Plan. The Compensation Committee may grant stock options, restricted stock, restricted stock units and similar equity awards permitted under our plans based on its judgment as to whether the complete compensation packages to our executives, including prior equity awards, are appropriate and sufficient to retain and incentivize the executives and whether the grants balance long-term versus short-term compensation. The Compensation Committee also considers our overall performance as well as the individual performance of each of our named executive officers, the potential dilutive effect of restricted stock awards, the dilutive and overhang effect of the equity awards, and recommendations from the Chief Executive Officer (other than with respect to his own equity awards).

Stock options are granted with an exercise price equal to the fair market value of our common stock on the date of grant.

Restricted stock is granted at the closing price of the Company's common stock on the grant date.

On January 3, 2023, our Compensation Committee granted Mr. Arthur and Mr. Rosenblum 2,500 and 1,000 shares of restricted stock, respectively. 25% of the shares of restricted stock vested on January 2, 2024 and 1/36 of the remaining shares of restricted stock will vest on monthly anniversaries thereafter.

Personal Benefits and Perquisites

All of our executives are eligible to participate in our employee benefit plans, including medical, dental, vision, life insurance, short-term and long-term disability insurance, flexible spending accounts, 401(k), and an Employee Stock Purchase Program. These plans are available to all full-time employees. In keeping with our philosophy to provide total compensation that is competitive within our industry, we offer limited personal benefits and perquisites to executive officers. You can find more information on the amounts paid for these perquisites to or on behalf of our named executive officers in our Summary Compensation Table.

Nonqualified Deferred Compensation

None of our named executive officers participates in or has account balances in nonqualified defined contribution plans or other nonqualified deferred compensation plans maintained by us. Our Board may elect to provide our officers and other employees with nonqualified defined contribution or other nonqualified deferred compensation benefits in the future if it determines that doing so is in our best interests.

Employment and Separation Agreements

Below are descriptions of the employment or separation agreements with our named executive officers. Furthermore, each of our executive officers has executed a form of our standard proprietary information and inventions assignment agreement.

David J. Arthur

Separation Agreement

On February 20, 2024 (the "Separation Date"), we entered into a separation and release agreement (the "Separation Agreement") with David J. Arthur, our President and Chief Executive Officer, which provides for Mr. Arthur's separation of employment, effective as of the Separation Date. Under the Separation Agreement, we paid Mr. Arthur a lump-sum payment equal to the amounts owed to him pursuant to Section 5(c)(ii) of that certain Amended and

Restated Employment Agreement. Under the terms of the Separation Agreement, Mr. Arthur has elected to receive such amounts in a lump sum.

Mr. Arthur will remain as our principal executive officer and provide services to the us in such capacity pursuant to a Consulting Agreement, dated February 20, 2024 (the "Consulting Agreement"). Pursuant to the Consulting Agreement, Mr. Arthur is required to devote at least one-fourth (1/4) of his time on a weekly basis (on average 10 or more hours/week) to performing the services set forth in the Consulting Agreement. In exchange for Mr. Arthur's services as set forth in the Consulting Agreement, Mr. Arthur will receive $10,417 per month. The term of the Consulting Agreement expires on February 20, 2025, unless earlier terminated by either party in accordance with the terms of the Consulting Agreement.

In addition, on the Separation Date, we entered into a Notice of Stock Option Amendment with Mr. Arthur (the "Notice of Stock Option Amendment"), pursuant to which the Board amended the stock options to purchase shares of common stock granted to Mr. Arthur on September 10, 2019, March 23, 2020, July 14, 2020, December 2, 2020 and January 20, 2022 pursuant to the Company's 2015 Equity Incentive Plan (the "Plan") to extend the post-termination exercise period from 90 days to 18 months upon the termination of Mr. Arthur's "Continuous Service" (as defined in the Plan) for any reason other than for "Cause" (as defined in the Plan), but not beyond the term of the applicable stock option, and subject to earlier termination (such as in connection with a "Corporate Transaction" (as defined in the Plan) as provided under the Plan.

Mr. Arthur also entered into an updated indemnification agreement with the Company (the "Indemnification Agreement") to reflect his change in status from an employee of the Company to a consultant.

Mark J. Rosenblum

On April 24, 2020, we entered into an Executive Employment Agreement with Mark J. Rosenblum, its Executive Vice President of Finance and Chief Financial Officer (the "Rosenblum Agreement"). Under the Rosenblum Agreement, Mr. Rosenblum was originally entitled to an annual base salary of $265,000. Mr. Rosenblum is also eligible to participate in, subject to applicable eligibility requirements, all of our benefits plans and fringe benefits and programs that may be provided to our executives from time to time. In December 2021 Mr. Rosenblum's base salary was increased to $300,000, which increase became effective January 1, 2022. In November 2022 Mr. Rosenblum's base salary was increased to $330,000, which increase became effective January 1, 2023.On February 20, 2024, we entered into an amendment to the Rosenblum Agreement to provide Mr. Rosenblum with the option to receive any severance that may be owed to him pursuant to Section 5(c)(i) thereof in equal installments over a period of time or in a lump-sum amount.

Clawback Policy

We have a compensation recoupment, or clawback, policy, which we adopted to comply with Nasdaq listing standards implementing Exchange Act Rule 10D-1. The clawback policy includes mandatory recoupment of excess incentive-based compensation received by a covered executive (including the Named Executive Officers) on or after October 2, 2023 in the event of a restatement of the Company's financial statements due to material non-compliance with any financial reporting requirement under federal securities laws, as required by Exchange Act Rule 10D-1.

Additional Narrative Disclosure: Termination-Based Compensation

The Rosenblum Agreement provides that, so long as Mr. Rosenblum executes a release and settlement agreement with the Company, and subject to applicable withholdings, he would be entitled to receive a cash severance and an amount for premium payments under COBRA. Under the Rosenblum Agreement, the cash severance is equal to 9 months and if Mr. Rosenblum elects continuation coverage under COBRA or state law equivalent or enrollment in an individual marketplace, we will pay him an amount equal to the 9 months' worth of total premium payments (or until the date the executive secures reasonably comparable coverage with another employer, if sooner). These payments to Mr. Rosenblum are required to be made upon the following termination events:

•In the event we or a successor entity terminates the executive's employment for any reason other than a termination for Cause, or in connection with death, a permanent disability, or our dissolution; and

•In the event that, within the 18-month period following a Change in Control of the Company or a successor entity terminates the executive's employment for any reason other than a termination for Cause or in connection with death, a permanent disability, or the Company's dissolution, or if the executive terminates his employment for Good Reason.

The following definitions have been adopted in the Rosenblum Agreement:

"for Cause" shall be determined by the board of managers by a majority vote (not including such employee with respect to an event related to him) and shall mean:

•any material breach, which is not cured within 30 days after written notice thereof, of the terms of Rosenblum Agreement by the executive, or the failure of the executive to diligently and properly perform his duties, or the executive's failure to achieve the objectives specified by the board of managers;

•the executive's misappropriation or unauthorized use of the tangible or intangible property of the Company, or any other similar agreement regarding confidentiality, intellectual property rights, non-competition or non-solicitation;

•any material failure to comply with company policies or any other policies and/or directives of the board of managers, which failure is not cured within 30 days after written notice thereof, provided that no cure period is available for a failure to comply with policies related to harassment, unlawful discrimination, retaliation or workplace violence;

•the executive's use of illegal drugs or any illegal substance, or alcohol in any manner that materially interferes with the performance of his duties under the Rosenblum Agreement;

•any dishonest or illegal action (including, without limitation, embezzlement) or any other action by the executive which is materially detrimental to the interest and well-being of the Company, including, without limitation, harm to its reputation;

•the executive's failure to fully disclose to us any material conflict of interest he may have in a transaction between the Company and any third party which is materially detrimental to the interest and well-being of the Company; or

•any adverse action or omission by the executive which would be required to be disclosed pursuant to public securities laws or which would limit the ability of us or our affiliates to sell securities under any Federal or state law or which would disqualify us or our affiliates from any exemption otherwise available to it.

"Good Reason" means the occurrence of any of the following actions taken by us without the executive's consent, but only if (a) the executive informs us within 90 days of its occurrence that an event constituting Good Reason has occurred (b) we fail to cure the event within 90 days of such notice, and (c) the executive terminates his employment within 6 months of the initial occurrence:

Pay Versus Performance Narrative Disclosure

In accordance with Item 402(v) of Regulation S-K, we are providing the following descriptions of the relationships between information presented in the Pay Versus Performance table on CAP and each of total stockholder return ("TSR") and net loss.

We do not utilize TSR and net loss in our executive compensation program. However, we do utilize several other performance measures to align executive compensation with our performance. As described in more detail above in the section of Summary Compensation Tables and Employment Agreements, part of the compensation our NEOs are eligible to receive consists of annual performance-based cash bonuses that are designed to provide appropriate incentives to our executives to achieve defined annual corporate goals and to reward our executives for individual achievement towards these goals, subject to certain employment criteria. Additionally, we view stock options, which are an integral part of our executive compensation program, as related to company performance although not directly tied to TSR, because they provide value only if the market price of our common stock increases, and if the executive officer continues in our employment over the vesting period. These stock option awards strongly align our executive officers' interests with those of our stockholders by providing a continuing financial incentive to maximize long-term value for our stockholders and by encouraging our executive officers to continue in our employment for the long-term.

With respect to net income, specifically, because we are not a commercial-stage company, we did not have any revenue during the periods presented, other than revenue associated with grants. Consequently, our company does

not consider net loss as a performance measure for our executive compensation program. In 2023, our net loss decreased from 2022 and 2021, respectively. This decrease was primarily due to the fact that we have curtailed our sponsored clinical trials and intend to rely on clinical trial data from the investigator initiated clinical trial conducted by MD Anderson Cancer Center in connection with our strategic alternatives review process.

The following graph illustrates the relationship during 2021-2023 of the CAP for our PEO and non-PEO NEO as calculated pursuant to SEC rules to our TSR assuming a $100 investment in our stock on December 31, 2020.

The following graph illustrates the relationship during 2021-2023 of the CAP for our CEO and other NEOs as calculated pursuant to SEC rules to our net loss.

The number of shares of our common stock authorized under the 2015 Equity Incentive Plan automatically increase on January 1st of each year, for a period of not more than ten years, commencing on January 1, 2016 and ending on (and including) January 1, 2025, in an amount equal to 4% of the total number of shares of capital stock outstanding on December 31st of the preceding calendar year. Notwithstanding the foregoing, the Board may act prior to January 1st of a given year to provide that there will be no January 1st increase in the share reserve under the 2015 Equity Incentive Plan for such year or that the increase in the share reserve for such year will be a lesser number of shares of common stock than would otherwise occur pursuant to the preceding sentence.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information as of October 25, 2024 regarding the number of shares of common stock and the percentage of common stock, beneficially owned by:

•each person, or group of affiliated persons, known by us to beneficially own more than 5% of our common stock;

•each of our directors;

•each of our named executive officers; and

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

The percentage ownership is based on 1,441,157 shares of common stock outstanding on October 25, 2024. We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of our common stock issuable pursuant to the exercise of stock options or warrants or other securities that are either immediately exercisable or exercisable or vest within 60 days of October 25, 2024. These shares are deemed to be outstanding and beneficially owned by the person holding those options, warrants, or securities for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

Except as otherwise noted below, the address for each person or entity listed in the table is c/o Salarius Pharmaceuticals, Inc., 2450 Holcombe Blvd., Suite X, Houston, TX 77021.

(1)On May 16, 2023, we issued to Armistice Capital, LLC ("Armistice Capital"), among other things, (i) Series A-1 warrants (the "Series A-1 Warrants") to purchase up to 454,546 shares of our common stock and (iv) Series A-2 warrants (the "Series A-2 Warrants") to purchase up to 454,546 shares of Common Stock. Series A-1 Warrants are exercisable for a period of five and one-half (5.5) years from the issuance date at an exercise price of $11.20 per share. The Series A-2 Warrants are exercisable for a period of eighteen (18) months from the issuance date at an exercise price of $11.20 per share. The amount reflected in the table excludes the Series A-1 Warrants and the Series A-2 Warrants because such warrants prohibit the investor from exercising the warrants to the extent such exercise would cause such investor, together with its affiliates and attribution parties, to beneficially own a number of shares of our common stock which would exceed 9.99% of our then outstanding common stock following such exercise. However, the investor can exercise such warrants up to the 9.99% blocker. The information below has been obtained from a Schedule 13G filed on February 14, 2024 by Armistice Capital. Armistice Capital is the investment manager of Armistice Capital Master Fund Ltd. (the "Master Fund"), the direct holder of the shares, and pursuant to an Investment Management Agreement, Armistice Capital exercises voting and investment power over the securities of the Company held by the Master Fund and thus may be deemed to beneficially own the securities of the Company held by the Master Fund. Mr. Steven Boyd, as the managing member of Armistice Capital, may be deemed to beneficially own the securities of the Issuer held by the Master Fund. The Master Fund specifically disclaims beneficial ownership of the securities of the Company directly held by it by virtue of its inability to vote or dispose of such securities as a result of its Investment Management Agreement with Armistice Capital.

CERTAIN RELATED-PERSON TRANSACTIONS

The following includes a summary of transactions since January 1, 2022 to which we have been a party, in which the amount involved in the transaction exceeded the lesser of $120,000 or one percent of the average of our total assets at year-end for the last two completed fiscal years, and in which any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our capital stock or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest, other than equity and other compensation, termination, change of control, and other arrangements, which are described under "Executive Compensation."

DeuteRX Transaction

On January 12, 2022, we entered into an Acquisition and Strategic Collaboration Agreement (the "ASCA"), with DeuteRx, LLC, a Delaware limited liability company (the "DeuteRx"), pursuant to which DeuteRx agreed to sell, and we agreed to purchase certain assets of DeuteRx, including the development product we refer to as DRX-3164 (collectively, the "Purchased Assets"). Dr. McVicar, a member of our Board, serves as a consultant to DeuteRx and is employed by an affiliate of DeuteRx.

The Purchased Assets were purchased for an aggregate purchase price of $1,500,000 and the delivery of 5,000 shares of our common stock. We also agreed to pay to DeuteRx (i) milestone payments upon the occurrence of certain events and (ii) royalty payments.

Indemnification Agreements

We have entered, and intend to continue to enter, into separate indemnification agreements with our directors and executive officers, in addition to the indemnification provided for in our Certificate of Incorporation and Bylaws. These agreements, among other things, require us to indemnify our directors and executive officers for certain expenses, including attorneys' fees, judgments, fines, and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of our directors or executive officers or as a director or executive officer of any other company or enterprise to which the person provides services at our request. We believe that these charter provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

The limitation of liability and indemnification provisions in our Certificate of Incorporation and Bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit us and our stockholders. A stockholder's investment may decline in value to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

Policies and Procedures for Transactions with Related Persons

We have adopted a written Related Person Transactions Policy that sets forth our policies and procedures regarding the identification, review, consideration, and oversight of "related person transactions." For purposes of our policy only, a "related person transaction" is a transaction, arrangement, or relationship (or any series of similar transactions, arrangements or relationships) in which we or any of our subsidiaries are participants involving an amount that exceeds $120,000, in which any "related person" has a material interest.

Transactions involving compensation for services provided to us as an employee, consultant, or director are not considered related person transactions under this policy. A related person is any executive officer, director, nominee to become a director or a holder of more than 5% of any class of our voting securities (including our common stock),

including any of their immediate family members and affiliates, including entities owned or controlled by such persons.

Under the policy, the related person in question or, in the case of transactions with a holder of more than 5% of any class of our voting securities, an officer with knowledge of the proposed transaction, must present information regarding the proposed related person transaction to our Audit Committee (or, where review by our Audit Committee would be inappropriate, to another independent body of our Board) for review. To identify related person transactions in advance, we rely on information supplied by our executive officers, directors, and certain significant stockholders. In considering related person transactions, our Audit Committee considers the relevant available facts and circumstances, which may include, but not limited to:

•the risks, costs, and benefits to us;

•the impact on a director's independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

•the terms of the transaction;

•the availability of other sources for comparable services or products; and

•the terms available to or from, as the case may be, unrelated third parties.

Our Audit Committee will approve only those transactions that it determines are fair to us and in our best interests.

AUDIT COMMITTEE REPORT

The following report of the Audit Committee does not constitute soliciting material and shall not be deemed filed or incorporated by reference into any other filing by the Company under the Securities Act of 1933 or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

The Audit Committee is a committee of the Board comprised solely of independent directors as required by the listing standards of Nasdaq and rules and regulations of the SEC. The Audit Committee provides assistance to the Board in fulfilling its legal and fiduciary obligations in matters involving the Company's accounting, auditing, financial reporting, internal control and legal compliance functions by approving the services performed by the Company's independent registered public accountants and reviewing their reports regarding the Company's accounting practices and systems of internal accounting controls as set forth in a written charter adopted by the Board, which is available on the Company's website at http://www.salariuspharma.com. The composition and responsibilities of the Audit Committee, as reflected in its charter, are intended to be in accordance with applicable requirements. The Audit Committee reviews and assesses the adequacy of its charter and the Audit Committee's performance on an annual basis.

The Company's management is responsible for preparing the Company's financial statements and the independent registered public accountants are responsible for auditing those financial statements. The Audit Committee is responsible for overseeing the conduct of these activities by the Company's management and the independent registered public accountants. In this context, the Audit Committee has met and held discussions with management and the independent registered public accountants. Management represented to the Audit Committee that the Company's consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent registered public accountants.

The Audit Committee has discussed with the independent registered public accountants matters required to be discussed by Auditing Standard No. 1301, as adopted by the PCAOB and approved by the SEC. In addition, the independent registered public accountants provided to the Audit Committee the written disclosures and letter from the independent registered public accountants as required by applicable requirements of the PCAOB regarding the independent registered public accountants' communications with the Audit Committee concerning independence and has discussed such accountants' independence from the Company and its management.

The Audit Committee has discussed with management the procedures for selection of consultants and fully considered whether those services provided by the independent registered public accountants are compatible with maintaining such accountants' independence. The Audit Committee has discussed with the Company's management and its independent registered public accountants, with and without management present, their evaluations of the Company's internal accounting controls and the overall quality of the Company's financial reporting.

In reliance on the reviews and discussions with management and the independent registered public accountants referred to above, the Audit Committee recommended to the Board, and the Board has approved, the inclusion of the audited financial statements in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for filing with the SEC.

In addition, the Audit Committee has selected Ernst & Young LLP as our independent registered public accounting firm to audit our books, records and accounts and our subsidiaries for the fiscal year ending December 31, 2024.

Respectfully submitted,

Mr. Arnold C. Hanish, Chair

Ms. Tess Burleson

Mr. Jonathan Lieber

PROPOSAL 1

ELECTION OF DIRECTORS

Directors and Nominees

Our Board consists of seven (7) directors which are divided into three classes: Class I, Class II, and Class III. Each class has a three-year term.

Our Board, upon the recommendation of the Nominating and Corporate Governance Committee, has nominated Tess Burleson and Paul Lammers as nominees for election as Class III directors at the Annual Meeting. If elected at the Annual Meeting, these directors would serve until the annual meeting of stockholders to be held in 2027 or until their respective successors are duly elected and qualified or until such individual's earlier resignation, removal, death or incapacity. If any nominee is unable or declines to serve as director at the time of the Annual Meeting, an event not now anticipated, proxies will be voted for any nominee designated by our Board to fill the vacancy.

Biographical information and the attributes, skills and experience of each nominee that led our Nominating and Corporate Governance Committee and Board to determine that such nominee should serve as a director are discussed in the "Directors and Executive Officers" section of this proxy statement and is incorporated into this section by reference.

Required Vote

Directors are elected by the affirmative vote of the holders of a majority of the voting power of the capital stock and entitled to vote present in person or represented by proxy at the Annual Meeting. Further, if the majority of the votes cast for a director are marked "AGAINST" or "ABSTAIN" then notwithstanding the valid election of such director, the Bylaws stipulate that such director will voluntarily tender his or her resignation for consideration by our Nominating and Corporate Governance Committee. Our Board will determine whether to accept the resignation of such director, taking into account the recommendation of the Nominating and Corporate Governance Committee.

OUR BOARD RECOMMENDS A VOTE "FOR" THE ELECTION OF TESS BURLESON AND PAUL LAMMBER AS CLASS III DIRECTORS OF THE COMPANY.

PROPOSAL 2

NON-BINDING ADVISORY VOTE ON EXECUTIVE COMPENSATION

The Dodd-Frank Act requires that we provide our stockholders with the opportunity to vote to approve, on a nonbinding, advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the compensation disclosure rules of the SEC.

Our executive compensation programs are designed to reward our named executive officers for the achievement of short-term and long-term strategic and operational goals, while at the same time avoiding the encouragement of unnecessary or excessive risk taking. Stockholders are encouraged to read the Executive Compensation section of this proxy statement for a more detailed discussion of how our compensation programs reflect our objectives.

We are asking our stockholders to indicate their support for our named executive officer compensation as described in this proxy statement. This proposal, commonly known as a "say-on-pay" proposal, gives our stockholders the opportunity to express their views on our named executive officers' compensation. This vote is advisory, which means that the vote on executive compensation is not binding on us, our Board or the Compensation Committee. This vote is not intended to address any specific item of compensation, but rather the vote relates to the compensation of our named executive officers as a whole, as described in this proxy statement in accordance with the compensation disclosure rules of the SEC. Accordingly, we will ask our stockholders to vote for the following resolution at the Annual Meeting:

"RESOLVED, that the Company's stockholders approve, on a non-binding advisory basis, the compensation of the named executive officers, as disclosed in the Company's proxy statement for the 2024 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the SEC, including the Summary Compensation Table and the other related tables and disclosure."

Required Vote

Approval of the compensation of our named executive officers on a non-binding advisory basis requires the affirmative vote of a majority of the voting power of the capital stock entitled to vote and present in person or represented by proxy at the Annual Meeting. An abstention has the same effect as a vote "AGAINST" Proposal 2. Broker non-votes will have no effect.

THE BOARD RECOMMENDS A VOTE "FOR" THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

PROPOSAL 3

RATIFICATION OF THE SELECTION OF INDEPENDENT REGISTERED PUBLIC

ACCOUNTING FIRM

Our Board has endorsed this appointment. Ratification of the selection of Ernst & Young LLP by stockholders is not required by law. However, as a matter of good corporate practice, such selection is being submitted to the stockholders for ratification at the Annual Meeting. If the stockholders do not ratify the selection, our Board and the Audit Committee will reconsider whether or not to retain Ernst & Young LLP, but may retain Ernst & Young LLP. Even if the selection is ratified, the Audit Committee in its discretion may change the appointment at any time during the year if it determines that such change would be in our best interests the best interests of our stockholders.

Audit Committee Pre-Approval Policies and Procedures

Our Audit Committee has implemented pre-approval policies and procedures related to the provision of audit and non-audit services. Under these procedures, the Audit Committee pre-approves both the type of services to be provided by Ernst & Young LLP and the estimated fees related to these services.

During the approval process, the Audit Committee considers the impact of the types of services and the related fees on the independence of the registered public accountant. The services and fees must be deemed compatible with the maintenance of such accountants' independence, including compliance with SEC rules and regulations.

Throughout the year, our Audit Committee reviews for any revisions to the estimates of audit and non-audit fees initially approved.

In the event the stockholders do not ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm, the Audit Committee will reconsider its appointment.

Required Vote

Ratification of the appointment of Ernst & Young LLP requires the affirmative vote of a majority of the voting power of the capital stock and entitled to vote and present in person or represented by proxy at the Annual Meeting. An abstention has the same effect as a vote "AGAINST" Proposal 3. Broker non-votes will have no effect. If your shares are held in street name, your broker, bank or other nominee has discretionary authority to vote shares held through it in the absence of your instruction regarding how your shares should be voted. Unless marked to the contrary, proxies received will be voted "FOR" ratification of the appointment.

THE BOARD RECOMMENDS A VOTE "FOR" THE RATIFICATION OF

ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2024.

OTHER MATTERS

The Board does not know of any other business that will be presented at the Annual Meeting. If any other business is properly brought before the Annual Meeting, the proxy holders will vote in accordance with their judgment unless you direct them otherwise. Whether or not you intend to attend the Annual Meeting, we urge you to vote by telephone or the Internet.

Availability of Annual Report on Form 10-K and Form 10-K/A

A copy of an Annual Report on Form 10-K and Form 10-K/A, including the financial statements and schedules thereto, required to be filed with the SEC for our most recent fiscal year, may be found on our website, investors.salariuspharma.com. In addition, we will provide each beneficial owner of our securities with a copy of the Annual Report without charge, upon receipt of a written request from such person. Such request should be sent to the office of our Corporate Secretary, Salarius Pharmaceuticals, Inc., 2450 Holcombe Blvd., Suite X, Houston, TX 77021.

Householding of Proxy Materials

To reduce the expense of delivering duplicate proxy materials to stockholders who may have more than one account holding our stock but who share the same address, we have adopted a procedure approved by the SEC called "householding." Under this procedure, certain stockholders of record who have the same address and last name will receive only one copy of our proxy materials until such time as one or more of these stockholders notifies us that they want to receive separate copies. This procedure reduces duplicate mailings and saves printing costs and postage fees, as well as natural resources. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

If you receive a single set of proxy materials as a result of householding and you would like to have separate copies of proxy materials mailed to you, please submit a request to our Secretary at 2450 Holcombe Blvd., Suite X, Houston, TX 77021 and we will promptly send you what you have requested. You can also contact our Secretary at the above address if you received multiple copies of the annual meeting materials and would prefer to receive a single copy in the future, or if you would like to opt out of householding for future mailings.

Stockholder Proposals for the 2025 Annual Meeting

To be considered for inclusion in next year's proxy materials, your proposal must be submitted in writing by July 4, 2025, to our Secretary at 2450 Holcombe Blvd., Suite X, Houston, TX 77021. If you wish to submit any other motion related to business proposed to be brought before next year's annual meeting of stockholders, you must provide the specified information required by our Bylaws to our Secretary at 2450 Holcombe Blvd., X, Houston, TX 77021 not more than 120 days (July 4, 2025) nor less than 90 days (August 3, 2025) prior to the first anniversary of the date the proxy statement was provided to our stockholders in connection with the 2024 Annual Meeting of stockholders; however, if the annual meeting is called for a date that is more than 30 days before or after the anniversary date of the 2024 annual meeting of stockholders, notice by the stockholder must be received by our Secretary not later than the close of business on the later of (i) the 90th day prior to the 2025 annual meeting of stockholders and (ii) the 10th day following the day on which public announcement of the date of the 2025 annual meeting of stockholders is publicly given. You are also advised to review our Bylaws, which contain additional requirements regarding advance notice of stockholder proposals and director nominations.
