Other Events. As previously reported, on December 30, 2025, the Company received a notification letter from The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that, for the last 30 consecutive business days, the closing bid price for the Company’s American Depositary Shares (the “ADSs”), has been below the minimum $1.00 per share required (the “Bid Price Requirement”) for continued listing on the Nasdaq Global Market pursuant to Nasdaq Listing Rule 5450(a)(1). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was given 180 calendar days, or until June 29, 2026, to regain compliance with the Bid Price Requirement pursuant to Nasdaq Listing Rule 5450(a)(1). On June 30, 2026, the Company received a notice (the “Extension Notice”) from Nasdaq informing the Company that Nasdaq had granted the Company an additional 180 calendar days, or until December 28, 2026, to regain compliance with the Bid Price Requirement for continued listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2). In connection with the Extension Notice, the listing of the ADSs was transferred from the Nasdaq Global Market to the Nasdaq Capital Market, effective as of July 2, 2026. The Extension Notice has no other immediate effect on the listing of the ADSs. The Company intends to continue actively monitoring the bid price for its ADSs between now and December 28, 2026, and will consider available options to resolve the deficiency and regain compliance with the Bid Price Requirement. These options include, but are not limited to, effecting a reverse stock split, if necessary, to attempt to regain compliance. If at any time before December 28, 2026, the closing bid price of the ADSs is at least $1.00 per share for a minimum of 10 consecutive business days (which may be extended to be a period of up to 20 consecutive business days at the discretion of the Staff), Nasdaq will provide written confirmation that the Company has regained compliance with the Bid Price Requirement. If the Company does not regain compliance within the additional compliance period, Nasdaq will provide notice that the ADSs will be subject to delisting. The Company would then be entitled to appeal that determination to a Nasdaq hearings panel. There is no assurance, however, that the Company will regain compliance with the Bid Price Requirement or that the ADSs will not be delisted from Nasdaq.
