Item 5.07			Submission of Matters to a Vote of Security Holders.

On December 19, 2025, Salarius Pharmaceuticals, Inc. (the “Company”) convened its 2025 annual meeting of stockholders (the “Annual Meeting”). At the Annual Meeting, there was not a sufficient number of shares of the Company’s common stock present or represented by proxy in order to constitute a quorum. As a result, the Company adjourned the Annual Meeting, without conducting any business.

As announced at the Annual Meeting, the Annual Meeting will reconvene on December 31, 2025 at 10:00 am Central Time and will continue to be held virtually via live webcast at www.virtualshareholdermeeting.com/SLRX2025. No changes have been made to the proposals to be voted on by the stockholders described in the Company’s definitive proxy statement filed with the Securities and Exchange Commission (the “SEC”) on November 7, 2025 (the “Definitive Proxy Statement”). The Company encourages all stockholders to review the Definitive Proxy Statement, along with all other related proxy materials, which are available free of charge on the SEC’s website at www.sec.gov.

The record date for determining stockholder eligibility to vote at the Annual Meeting will remain the close of business on October 24, 2025. Proxies previously submitted will be voted at the Annual Meeting unless properly revoked, and the stockholders who have already submitted a proxy or otherwise voted need not take any action.


Item 7.01			Regulation FD Disclosure.

On December 19, 2025, the Company issued a press release announcing the convening and adjournment of the Annual Meeting and the information for the reconvened Annual Meeting. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.
