BEST SPAC I Acquisition Corp.

Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. On August 19, 2026, BEST SPAC I Acquisition Corp. (the “Company”) received a letter from The Nasdaq Stock Market LLC (“Nasdaq”), which stated that, based upon a review of the Company’s Market Value of Listed Securities (MVLS) for the last 30 consecutive business days, the Company no longer meets the minimum MVLS of $35,000,000 required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(2). The Company also does not meet the requirements under Listing Rules 5550(b)(1) and 5550(b)(3). The notification has no immediate effect on the listing of the Company’s securities, and its units, Class A ordinary shares and rights will continue to trade on Nasdaq under the symbol “BSAAU,” “BSAA” and “BSAAR,” respectively, at this time. In accordance with the Nasdaq listing rules, the Company has been provided a compliance period of 180 calendar days, or until February 15, 2027, in which to regain compliance. In the event the Company does not regain compliance with the MVLS requirement prior to the expiration of the compliance period, it will receive written notification that its securities are subject to delisting. At that time, the Company may appeal the delisting determination to a Hearings Panel. There is no assurance that the Company will be able to regain compliance with the Nasdaq listing rules prior to the expiration of the compliance period or at all. This announcement is made in compliance with Nasdaq Listing Rule 5810(b), which requires prompt disclosure of receipt of a deficiency notification.
