ACHL Achilles Therapeutics PLC

Achilles Therapeutics plc (NASDAQ: ACHL) today announced that on November 15, 2024, the Listing Qualifications department of the Nasdaq Stock Market LLC ("Nasdaq") approved the Company's request to transfer the listing of the Company's American Depositary Shares (the "ADSs") from the Nasdaq Global Market to the Nasdaq Capital Market. The transfer is expected to take effect at the opening of business on November 19, 2024.

The transfer of the Company's listing to the Nasdaq Capital Market is not expected to have any impact on trading in the Company's ADSs. The Company's ADSs will continue to trade under the symbol "ACHL." The approval by Nasdaq was conditioned upon the Company meeting the applicable market value requirement of publicly held shares for continued listing and all other applicable requirements for listing on the Nasdaq Capital Market.

As previously disclosed, on May 17, 2024, the Company received a letter from Nasdaq indicating that the Company was not in compliance with Nasdaq Listing Rule 5450(a)(1), as the closing bid price of the ADSs had been below US$1.00 per ADS for the previous 30 consecutive business days. The Company was given a period of 180 calendar days to regain compliance with the minimum bid price requirement. In response, the Company submitted an application to transfer the listing of its ADSs from the Nasdaq Global Market to the Nasdaq Capital Market.

As a result of the transfer to the Nasdaq Capital Market, the Company will be eligible for an additional 180 calendar days to regain compliance with the requirements set forth in Nasdaq Listing Rule 5450(a)(1) that the bid price of the Company’s shares meet or exceed $1.00 per share for at least ten consecutive business days (the “Minimum Bid Price Rule”).

The Company intends to continue to actively monitor the minimum bid price requirement and, as appropriate, will consider available options to resolve any deficiencies and regain compliance.
