Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On April 6, 2026, DT Cloud Star Acquisition Corporation (the “Company”) received a letter (the “Deficiency Letter”) from the Listing Qualifications Staff of The Nasdaq Stock Market (“Nasdaq”) indicating that based on a shareholder range analysis provided by the Company to Nasdaq dated March 27, 2026, the Company is not in compliance with Listing Rule 5450(a)(2) (the “Minimum Public Holders Rule”), which requires the Company to maintain at least 400 total holders for continued listing on The Nasdaq Global Market. The Deficiency Letter is only a notification of deficiency, not of imminent delisting, and has no current effect on the listing or trading of the Company’s securities on the Nasdaq Global Market.

The Deficiency Letter states that the Company has 45 calendar days, or until May 21, 2026, to submit a plan to regain compliance with Listing Rule 5450(a)(2). If Nasdaq accepts the Company’s plan, Nasdaq may grant the Company an extension of up to 180 calendar days from the date of the Deficiency Letter to evidence compliance with Listing Rule 5450(a)(2). If Nasdaq does not accept the Company’s plan, the Company will have the opportunity to appeal the decision to a Nasdaq Hearings Panel. The Company may also consider applying for a transfer to The Nasdaq Capital Market (the “Capital Market”).

The Company is exploring all options to regain compliance with Listing Rule 5450(a)(2) and intends to submit a plan to regain compliance within the required timeframe. Although the Company will use all reasonable efforts to achieve compliance with Rule 5450(a)(2), there can be no assurance that the Company will be able to regain compliance with that rule or will otherwise be in compliance with other Nasdaq continued listing requirements.
