As previously disclosed, on January 22, 2026, the Company received written notice (the “Letter”) from the Nasdaq notifying the Company that it is not in compliance with the Minimum Bid Price Requirement, as the closing bid price for the Company’s Class A ordinary shares had been below $1.00 per share for the period from December 4, 2025 to January 21, 2026. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company had 180 calendar days to regain compliance, or until July 21, 2026 (the “Compliance Period”), to regain compliance with the Minimum Bid Price Requirement. To regain compliance with the Minimum Bid Price Requirement, the closing bid price of the Company’s Class A ordinary shares must be at least $1.00 per share for a minimum of 10 consecutive business days at any time prior to the expiration of Compliance Period.

According to the Compliance Letter, for the last 10 consecutive business days, from June 22, 2026 to July 6, 2026, the closing bid price of the Company’s Class A ordinary shares has been at $1.00 per share or greater.
