Item 8.01. Other Events

On October 10, 2025, Salarius Pharmaceuticals, Inc. (“Salarius”) received a letter from the Nasdaq Hearings Panel (the “Hearings Panel”) of The Nasdaq Stock Market LLC (“Nasdaq”) notifying Salarius that it has regained compliance with the minimum stockholders’ equity requirement set forth in Nasdaq Listing Rule 5550(b)(1) (the “Equity Standard”), as required by the Hearings Panel.

Nasdaq further notified Salarius that it will be subject to a Mandatory Panel Monitor for a period of one year from October 10, 2025. If, within that one-year monitoring period, the Listing Qualifications Staff (the “Staff”) finds Salarius again out of compliance with the Equity Standard that was the subject of the exception, Salarius will not be permitted to provide the Staff with a plan of compliance with respect to that deficiency and the Staff will not be permitted to grant additional time for Salarius to regain compliance with respect to that deficiency, nor will the company be afforded an applicable cure or compliance period pursuant to Nasdaq Listing Rule 5810(c)(3). Instead, the Staff will issue a delisting determination letter and Salarius will have the opportunity to request a hearing with the Hearings Panel.

On October 13, 2025, Salarius issued a press release announcing that that it had regained compliance with the Equity Standard. A copy of the press release is filed herewith as Exhibit 99.1 and is incorporated herein by reference.
