EXPLANATORY NOTE

The registrant is filing this Amendment No. 1 to Annual Report on Form 10-K/A, or this Amendment (also referred to herein as this report), to amend the Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (Commission File Number 001-36812), or the 2023 Annual Report on Form 10-K, as filed by the registrant with the Securities and Exchange Commission, or the SEC, on March 22, 2024. The purpose of this Amendment is to include in Part III the information that was to be incorporated by reference from the proxy statement for the registrant’s 2024 Annual Meeting of Stockholders, as well as to update certain of the information included on the cover page of the 2023 Annual Report on Form 10-K and in the list of exhibits included in Item 15 and the Exhibit Index of this report. The Part III information was previously omitted from the 2023 Annual Report on Form 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in Items 10 through 14 of Part III of Form 10-K to be incorporated in the Form 10-K by reference from the registrant’s definitive proxy statement if such statement is filed not later than 120 days after the registrant’s fiscal year-end. The registrant is filing this Form 10-K/A to include Part III information in the 2023 Annual Report on Form 10-K because the registrant does not expect to file a definitive proxy statement containing such information within 120 days after the end of the fiscal year covered by the 2023 Annual Report on Form 10-K. This Amendment hereby amends the cover page, Part III, Items 10 through 14, and Part IV, Item 15 of the 2023 Annual Report on Form 10-K. In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, new certifications by the registrant’s principal executive officer and principal financial officer are filed as exhibits to this Amendment.

No attempt has been made in this Amendment to modify or update the other disclosures presented in the 2023 Annual Report on Form 10-K. This Amendment does not reflect events occurring after the filing of the 2023 Annual Report on Form 10-K (i.e., those events occurring after March 22, 2024) or modify or update those disclosures that may be affected by subsequent events. Accordingly, this Amendment should be read in conjunction with the 2023 Annual Report on Form 10-K and the registrant’s other filings with the SEC.

In this report, unless otherwise indicated or the context otherwise requires, all references to “Salarius,” “the registrant,” “the Company,” “we,” “us,” and “our” refer to Salarius Pharmaceuticals, Inc. together with its wholly owned subsidiaries. On October 14, 2022, the registrant effected a 1-for-25 reverse split of shares of its common stock. All share and per share data in this report gives effect to the reverse stock split.

Family Relationships

There are no family relationships among any of our directors or executive officers.

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 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. The Board of Directors has determined that each of the members of the Audit Committee satisfies Nasdaq and SEC independence requirements. The Board of Directors has determined that Mr. Hanish qualifies as an audit committee financial expert within the meaning of SEC regulations and meets the financial sophistication requirements of the Nasdaq Listing Rules. 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.

The functions of this committee include, among other things:

•selecting, on behalf of the Board of Directors, an independent public accounting firm to audit our financial statements;

•reviewing our financial reporting processes and disclosure controls;

•discussing with the independent auditors their independence, reviews and discusses our audited financial statements with the independent auditors and management;

•recommending to the Board of Directors whether the audited financials should be included our annual reports to be filed with the SEC;

•reviewing and considering “related person transactions” under our Related Person Transaction Policy; and

•reviewing any proposed waiver of our Code of Business Conduct and Ethics and Code of Ethics for Senior Financial Officers and making recommendations to the Board of Directors with respect to the disposition of any proposed waiver.

We believe that the composition and functioning of our Audit Committee complies with all applicable requirements of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”) and all applicable SEC rules and regulations. We intend to comply with future requirements to the extent they become applicable to us.

Compensation Committee

Our Compensation Committee currently consists of Ms. Burleson, Mr. Hanish, and Dr. Lammers. Dr. Lammers serves as the chair of our Compensation Committee. The Board of Directors has determined that each of the members of the Compensation Committee is a non-employee director, as defined in Rule 16b-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Additionally, the Board has determined that each of the members of the Compensation Committee satisfies Nasdaq and SEC independence requirements.

The functions of this committee include, among other things:

•reviewing and approving the corporate objectives that pertain to the determination of executive compensation;

•reviewing and approving the compensation and other terms of employment of our executive officers;

•reviewing and approving performance goals and objectives relevant to the compensation of our executive officers and assessing their performance against these goals and objectives;

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee consists of Ms. Burleson, Dr. McCreedy and Mr. Lieber. Ms. Burleson serves as the chair of our Nominating and Corporate Governance Committee.

We believe that the composition and functioning of our Nominating and Corporate Governance Committee complies with all applicable requirements of the Sarbanes-Oxley Act and all applicable SEC and Nasdaq rules and regulations. 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 120 days nor less than 90 days prior to the anniversary of the previous year’s proxy statement provided in connection with the previous year’s annual meeting of stockholders. 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.

Stockholder nominations must be made in accordance with the procedures outlined in, and include the information required by, our Bylaws and must be addressed to: Secretary, Salarius Pharmaceuticals, Inc., 2450 Holcombe Blvd. Suite X, Houston, TX 77021. 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. This process will assist our Board in reviewing and responding to stockholder communications in an appropriate manner. Our Board has instructed our Secretary to review such correspondence and, at his discretion, not to forward items if he deems them to be of a commercial or frivolous nature or otherwise inappropriate for our Board’s consideration such as spam, junk mail and mass mailings, product complaints, personal employee complaints, product inquiries, new product suggestions, resumes and other forms of job inquiries, surveys, business solicitations, or advertisements.

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. 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 20,000 and 8,000 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.

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”).

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. 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 November 2022 Mr. Rosenblum’s base salary was increased to $330,000, which increase became effective January 1, 2023.

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:

“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:

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. In addition, the Board believes that a significant portion of director compensation should align director interests with the long-term interests of stockholders. 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. The Compensation Committee believes that our non-employee director compensation remains aligned with director compensation practices at our peer companies while considering the ongoing cash constraints of the Company.

Cash Compensation

For 2023,our non-employee director cash compensation policy provides that non-employee directors receive a $40,000 annual retainer, with an additional $20,000 annual retainer for our former lead independent director, an additional $40,000 annual retainer for the chair of the Board, and the following additional retainers for committee services:


Committee	Chair 2023	Member 2023
Compensation Committee	$13,500	$5,000
Nominating and Corporate Governance Committee	$10,000	$4,000
Audit Committee	$20,000	$7,500

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

Stock Ownership

Stock Ownership of Directors, Officers and Principal Stockholders

The following table sets forth information as of April 11, 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 4,314,433 shares of common stock outstanding on April 11, 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 April 11, 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)This information has been obtained from a Schedule 13G filed on February 14, 2024 by Armistice Capital, LLC (“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. The principal business address for Armistice Capital, LLC is 510 Madison Avenue, 7th Floor, New York, New York 10022, United States of America. The principal business address for Mr. Boyd is c/o Armistice Capital, LLC, 510 Madison Avenue, 7th Floor, New York, New York 10022, United States of America. The amounts in the table excluded pre-funded warrants, Series A-1 warrants and Series A-2 warrants to purchase share of our common stock held by entities affiliated with Armistice Capital because such warrants prohibits 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.

(2)Represents (i) 49,135 shares of common stock, (ii) 37,908 shares of common stock subject to options that are exercisable within 60 days of April 12, 2024 and (iii) 87 warrants to purchase shares of common stock.

Item 13. Certain Relationships and Related Transactions, and Director Independence

Transactions with Related Persons

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 previously referred to as DRX-164 (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 40,000 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.

Director Independence

See Item 10 "Directors, Executive Officers, and Corporate Governance" for additional information regarding director independence.

Item 14. Principal Accounting Fees and Services

Ernst & Young LLP, or EY, was our independent registered public accounting firm for the years ended December 31, 2023 and December 31, 2022.

(3)Consists of fees billed for tax compliance, tax advice, tax planning and tax return preparation.

(4)Consists of fees billed for services, other than those described above under Audit fees and Tax fees.

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. The Audit Committee reviewed and pre-approved all audit services and permitted non-audit services performed during the years ended December 31, 2023 and 2022.
