CALLAN JMB INC.

We are a smaller reporting company as defined by Rule 12b-2 of the Securities Exchange Act of 1934 and, as such, are not required to provide the information under this Item. Notwithstanding the foregoing, the following risk factor supplements the risk factors, if any, previously disclosed in our filings with the SEC.

Our common stock may be delisted from The Nasdaq Capital Market if we do not regain compliance with Nasdaq’s continued listing requirements.

On April 7, 2026, we received a deficiency letter (the “Notice”) from Nasdaq notifying us that we were not in compliance with Nasdaq Listing Rule 5550(b)(1), which requires a minimum of $2,500,000 in stockholders’ equity for continued listing on The Nasdaq Capital Market. We have until May 22, 2026 to submit a plan to regain compliance, and if Nasdaq accepts the plan, Nasdaq may grant us up to 180 calendar days from the date of the Notice, or until October 4, 2026, to evidence compliance. The Notice does not have an immediate effect on the listing or trading of our common stock; however, if Nasdaq does not accept our plan or if we fail to regain compliance within the applicable period, our common stock could be delisted, which could adversely affect the liquidity and market price of our common stock and our ability to raise capital.
