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

On April 29, 2025, Distoken Acquisition Corporation (the “Company”) received a deficiency letter from the Listing Qualifications Department (the “Staff”) of the Nasdaq Stock Market (“Nasdaq”) notifying the Company that, for the preceding 30 consecutive business days, the Company’s Market Value of Publicly Held Shares (“MVPHS”) was below the $15 million minimum requirement under the continued listing standards of The Nasdaq Global Market pursuant to Nasdaq Listing Rule 5450(b)(2) (the “MVPHS Requirement”).

The notification received has no immediate effect on the Company’s Nasdaq listing. The Nasdaq rules provide the Company a compliance period of 180 calendar days, or until October 27, 2025, in which to regain compliance. If at anytime during this compliance period the Company’s MVPHS closes at $15 million or more for a minimum of ten consecutive business days, Nasdaq will provide the Company written confirmation of compliance.

The Company intends to monitor its MVPHS and may, if appropriate, consider available options to regain compliance with the MVPHS Requirement and continue the listing of its securities on Nasdaq.
