Reverse stock split description | the Company effected a 15-for-1 reverse stock split of its common stock which was made effective for trading purposes as of 12:01 a.m. ET on July 25, 2025. As of that date, each 15 shares of issued and outstanding common stock and equivalents were consolidated into one share of common stock. All shares have been restated to reflect the effects of the 15-for-1 reverse stock split. In addition, at the market open on July 25, 2025, the Company’s common stock started trading under a new CUSIP number 15117N701 although the Company’s ticker symbol, IMNN, remained unchanged |  |  |  |
NASDAQ capital market description | The NASDAQ Capital Market, which requires that the Company comply with the applicable listing requirements under NASDAQ Marketplace Rules, which requirements include, among others, a minimum bid price of at least $1.00 per share. On November 26, 2024, the Company received a letter from NASDAQ indicating that the closing bid price of the Company’s Common Stock fell below $1.00 per share for the previous 30 consecutive business days, and that the Company was therefore not in compliance with the minimum bid price requirement for continued inclusion on The NASDAQ Capital Market. The Company had 180 calendar days, until May 27, 2025, to regain compliance with this requirement, which occurs when the closing bid price of the Company’s Common Stock is at least $1.00 per share for a minimum of ten consecutive business days during the 180-day compliance period. As of May 27, 2025, we were not eligible for an additional 180 calendar day compliance period, as we did not meet the required Nasdaq initial listing standards, and, on May 28, 2025, we received a delisting notice from Nasdaq. We also received a notice from the Staff notifying us that, because our stockholders’ equity was below $2.5 million as reported on our Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, we no longer meet the minimum stockholders’ equity requirement for continued listing on Nasdaq under Nasdaq Rule 5550(b)(1). |  |  |  |
