On November 2, 2023, Acer Therapeutics Inc. filed a Form 8-K that included the following information regarding its delisting from The Nasdaq Stock Market:
Item 3.01. Notice of Delisting or Failure to Satisfy Continued Listing Rule or Standard; Transfer of Listing.
On October 31, 2023, the Company, received a letter (the “Delisting Notification”) from the staff (the “Staff”) of the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) stating that Nasdaq will suspend trading in the Company’s common stock, $0.0001 par value per share (“Common Stock”), effective at the opening of trading on November 9, 2023, because the Company had not regained compliance with the Nasdaq Listing Rule 5550(b)(2) (the “MVLS Rule”), which requires a listed company to have at least $35 million in market value of listed securities (“MVLS”) in order to qualify for continued listing on The Nasdaq Capital Market, during the grace period previously granted to the Company.
As previously reported in the Company’s Form 8-K filed on May 4, 2023, the Staff initially notified the Company on May 3, 2023 that the Company had not been in compliance with the MVLS Rule for a period of 30 consecutive business days. The Staff granted the Company a period of 180 calendar days, or until October 30, 2023, to regain compliance with the MVLS Rule.
Pursuant to the Delisting Notification, the Company has until 4:00 p.m. Eastern Time on November 7, 2023 to submit a written request to appeal the Staff’s delisting determination by the Nasdaq Hearings Panel (the “Hearings Panel”). Unless the Company submits a timely request for the Hearings Panel’s review of the Staff’s delisting determination, a Form 25-NSE will be filed with the SEC, which will remove the Company’s securities from listing and registration on The Nasdaq Capital Market. The Company does not intend to file an appeal, and therefore, trading of the Company’s Common Stock will be suspended at the opening of business on November 9, 2023, and a Form 25-NSE will be filed with the SEC, which will remove the Company’s securities from listing and registration on The Nasdaq Capital Market. If the Merger (as defined below) is not approved at the Company’s special meeting of stockholders on November 8, 2023, the Company’s shares will begin trading on OTC Pink Market starting on November 9, 2023.
