Explanatory Note

As previously reported, on October 2, 2024, SAIHEAT Limited (the “Company”) received notification (the “Notice”) from the Nasdaq Stock Market, LLC (“Nasdaq”) notifying the Company that the minimum bid price per share of its Class A ordinary shares was below $1.00 for a period of 30 consecutive business days between August 20, 2024 and October 1, 2024, and that the Company failed to meet the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”).

The Company was provided 180 calendar days, or until March 31, 2025, to regain compliance with the Minimum Bid Price Requirement.

Since then, Nasdaq has determined that for the last 12 consecutive business days, from March 17, 2025 through April 1, 2025, the closing bid price of the Company’s Class A ordinary shares has been at $1.00 per share or greater. On April 2, 2025, Nasdaq notified the Company that it has regained compliance with the Minimum Bid Price Requirement and the matter is now closed.
