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

As previously disclosed, on April 7, 2026, Callan JMB Inc. (the “Company”) received a deficiency letter from the Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that it was not in compliance with Nasdaq Listing Rule 5550(b)(1), which requires the Company to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing on The Nasdaq Capital Market (the “Stockholders’ Equity Requirement”). The Staff granted the Company an extension until October 5, 2026 to regain compliance with the Stockholders’ Equity Requirement.

On October 12, 2026, the Company received a letter from the Staff (the “Staff Determination”) notifying the Company that, because the Company was unable to complete its capital raising initiatives and demonstrate compliance with the Stockholders’ Equity Requirement, the Staff has determined that the Company did not meet the terms of the extension. As a result, unless the Company requested an appeal of the Staff Determination by October 19, 2026, trading of the Company’s common stock will be suspended at the opening of business on October 21, 2026, and a Form 25-NSE will be filed with the Securities and Exchange Commission (the “SEC”), which will remove the Company’s securities from listing and registration on Nasdaq.

Pursuant to Nasdaq Listing Rule 5815(a), on October 14, 2026 the Company requested a hearing before a Nasdaq Hearings Panel (the “Panel”) to appeal the Staff Determination. The hearing request will stay the suspension of the Company’s common stock and the filing of the Form 25-NSE pending the Panel’s decision. The Company intends to vigorously demonstrate its compliance with the Stockholders’ Equity Requirement before the Panel. There can be no assurance that the Panel will grant the Company’s request for continued listing or that the Company will be able to regain compliance with the Stockholders’ Equity Requirement or maintain compliance with any other Nasdaq listing requirement.
