Item 8.01. Other Events.

On July 15, 2025, Lixte Biotechnology Holdings, Inc. (the “Company”) received notice from The Nasdaq Stock Market LLC that the Nasdaq Hearings Panel found that the Company was in compliance with Listing Rule 5550(b)(1) (the “Equity Rule”). The Company was also notified that it will remain subject to a “Panel Monitor”, as that term is defined in Nasdaq Listing Rule 5815(d)(4)(B), for a period of one year from the date of the Nasdaq notice, through July 15, 2026. If, during the term of the Panel Monitor, the Company does not continue to remain in compliance with the Equity Rule, the Company will not be provided with the opportunity to submit a compliance plan for review by the Listing Qualifications Staff and must instead request a hearing before the Panel to address the deficiency, with such request staying any further action with respect to the Company’s listing on Nasdaq pending completion of the hearing process.

On July 16, 2025, the Company issued a press release announcing the regaining of compliance with the Equity Rule. A copy of the press release is filed as Exhibit 99.1 hereto and is incorporated by reference.
