Announcement of Receipt of Nasdaq Deficiency Notice Regarding Minimum Bid Price Requirement

On March 28, 2022, ASLAN Pharmaceuticals Limited (the “Company”) received a notice (the “Notice”) from the Nasdaq Stock Market LLC (“Nasdaq”) that the Company is not currently in compliance with the $1.00 minimum bid price requirement for continued listing on the Nasdaq Global Market, as set forth in Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Price Requirement”).  The Notice indicated that, consistent with Nasdaq Listing Rule 5810(c)(3)(A), the Company has 180 days, or until September 26, 2022 (the “Compliance Deadline”), to regain compliance with the Minimum Bid Price Requirement by having the closing bid price of the Company’s ADSs meet or exceed $1.00 per ADS for at least ten consecutive business days. The Notice is only a notification of deficiency and has no immediate effect on the listing of the Company’s ADSs.  The Company’s ADSs will continue to trade on the Nasdaq Global 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 Company announced the receipt of the Notice through a press release on April 1, 2022 (the “Press Release”), which is attached hereto as Exhibit 99.1.

If the Company does not regain compliance by the Compliance Deadline, the Company may be afforded an additional 180 calendar day period to regain compliance. To qualify, the Company would be required to transfer to the Nasdaq Capital Market and meet the continued listing requirement for market value of publicly held securities and all other initial listing standards for the Nasdaq Capital Market, except for the Minimum Bid Price Requirement. In addition, the Company would be required to notify Nasdaq of its intent to cure the deficiency during the second compliance period. Following a transfer to the Nasdaq Capital Market, the Company would be afforded the second 180 calendar day period to regain compliance, unless it does not appear to Nasdaq that it is possible for the Company to do so. If the Company does not regain compliance with the Minimum Bid Price Requirement by the end of the compliance period (or the second compliance period, if applicable), the Company’s ADSs will become subject to delisting. In the event that the Company receives notice that its ADSs are being delisted, the Nasdaq listing rules permit the Company to appeal a delisting determination to a Nasdaq hearings panel.

There can be no assurance, however, that the Company will be able to regain compliance with the Minimum Bid Price Requirement, and even if it does, there can be no assurance that the Company will be able to maintain compliance with the continued listing requirements for the Nasdaq Global Market (or, potentially, the Nasdaq Capital Market) or that the Company’s ADSs will not be delisted in the future. In addition, the Company may be unable to meet other applicable listing requirements of the Nasdaq Global Market (or, potentially, the Nasdaq Capital Market), including maintaining minimum levels of shareholders’ equity or market values of the Company’s ADSs, in which case, the ADSs could be delisted notwithstanding the Company’s ability to demonstrate compliance with the Minimum Bid Price Requirement.

Delisting from the Nasdaq Global Market may adversely affect the Company’s ability to raise additional financing through the public or private sale of equity securities, may significantly affect the ability of investors to trade the Company’s securities and may negatively affect the value and liquidity of the Company’s ADSs. Delisting also could have other negative results, including the potential loss of employee confidence, the loss of institutional investors or interest in business development opportunities.
