PRESS RELEASE

ASLAN PHARMACEUTICALS ANNOUNCES RECEIPT OF NASDAQ DEFICIENCY NOTICE REGARDING MINIMUM BID PRICE REQUIREMENT

San Mateo, California, and Singapore, January 8, 2024 - ASLAN Pharmaceuticals (NASDAQ: ASLN) (“ASLAN” or the “Company”), announced today that on January 5, 2024, it received a written notice (the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company is not in compliance with the US$1.00 minimum bid price requirement under the Nasdaq Listing Rules (the “Listing Rules”). Based on the closing bid price of the Company’s listed securities for the 30 consecutive business days ended January 4, 2024, the Company has not met the minimum bid price requirement set forth in Listing Rule 5550(a)(2) during that period. The Notice is only a notification of deficiency and has no immediate effect on the listing of the Company’s American Depositary Shares (“ADS”). The Company’s ADSs will continue to trade on the Nasdaq Capital Market at this time. The Company’s receipt of the Notice does not impact the Company’s business, operations or reporting requirements with the Securities and Exchange Commission.

The Notice states that under Listing Rule 5810(c)(3)(A) the Company is provided with a period of 180 calendar days, or until July 3, 2024, to regain compliance with the Listing Rules. To regain compliance with the Listing Rules, the closing bid price of the Company’s ADSs must meet or exceed US$1.00 per ADS for at least ten consecutive business days. In the event the Company does not regain compliance by July 3, 2024, the Company may be eligible for an additional 180 calendar day period to regain compliance or may face delisting.

The Company intends to continue to monitor the closing bid price of its ADSs between now and July 3, 2024, and to evaluate its available options to regain compliance.

The Company fully intends to resolve the deficiency and regain compliance with the Listing Rules.
