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

On October 7, 2026, Plum Acquisition Corp. IV (the “Company”) received a written notice (the “Notice”) from the staff of the Listing Qualifications Department of the Nasdaq Stock Market LLC (“Nasdaq”), notifying the Company that the Company was not in compliance with Listing Rule 5450(a)(2), which requires the Company to have at least 400 total holders for continued listing on the Nasdaq Global Market (the “Minimum Total Holders Requirement”). The Notice is only a notification of deficiency, not of imminent delisting, and has no immediate effect on the listing or trading of the Company’s securities on the Nasdaq Global Market.

The Notice states that the Company has 45 calendar days to submit a plan to regain compliance with the Minimum Total Holders Requirement. 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 Notice to evidence compliance with the Minimum Total Holders Requirement. 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 is considering actions that it may take in response to the Notice to regain compliance with the Minimum Total Holders Requirement. However, there can be no assurance that the Company will regain compliance with such requirement.
