Subsequent Events [Abstract] |
Subsequent Events | Note 12. Subsequent Events The Company has evaluated its subsequent events from June 30, 2025, through the date these condensed consolidated financial statements were issued. On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes a number of significant provisions, including the permanent extension of certain expiring provisions of the 2017 Tax Cuts and Jobs Act. Additionally, the OBBBA contains changes to the capitalization of research and development expenses, accelerated fixed asset depreciation, and limitations on deductions for interest expense, among other provisions. The Company is still evaluating the impact of the OBBBA. Reverse Stock Split On July 25, 2025, 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. The reverse stock split was previously approved by the Company’s stockholders at the 2025 Annual Meeting held on July 11, 2025, and the Company subsequently filed a Certificate of Amendment to its Certificate of Incorporation to effect the stock consolidation. The primary reasons for the reverse stock split and the amendment are:
| ● | To provide the Company with the ability to support its future anticipated growth and would provide greater flexibility to consider and respond to future business opportunities and needs as they arise, including equity financings and stock-based acquisitions of new technology and product development candidates. The availability of additional shares of Common Stock would permit the Company to undertake certain of the foregoing actions without delay and expense associated with holding a Special Meeting of Stockholders to obtain stockholder approval each time such an opportunity arises that would require the issuance of shares of Common Stock; and
| ● | To continue listing on 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). On May 29, 2025, the Company requested a hearing before The Nasdaq Hearings Panel (“Panel”). At this hearing, the Company requested an extension to meet the requirements and return to compliance. A reverse stock split is a potentially effective means for the Company to regain and maintain compliance with Nasdaq Marketplace Rules and to avoid, or at least mitigate, the likely adverse consequences of common stock being delisted from The Nasdaq Capital Market by producing the immediate effect of increasing the bid price of common stock.
Immediately prior to the reverse stock split, the Company had 31,828,425 shares of common stock outstanding which consolidated into 2,121,895 shares of the Company’s common stock. No fractional shares were issued in connection with the reverse stock split. All fractional shares will be rounded up to the nearest whole share. The reverse stock split did not impact the total authorized number of shares of common or preferred stock or the par value thereof. The number of outstanding options, stock awards and warrants were adjusted accordingly, with outstanding options and stock awards being reduced from approximately 1.9 million to approximately 0.1 million and outstanding warrants being reduced from approximately 12.7 million to approximately 0.8 million. Increase to Authorized Shares At the 2025 Annual Meeting of Stockholders (the “Annual Meeting”) of the Company held on July 11, 2025, upon the recommendation of the Company’s board of directors, the Company’s stockholders voted on and approved an amendment to the Company’s Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 112,500,000 shares to 350,000,000 shares, and to make a corresponding change to the number of authorized shares of capital stock. Such amendment became effective on July 11, 2025 upon filing with the Secretary of State of the State of Delaware. Stock Dividend On July 28, 2025, the Company announced that the Company’s Board of Directors approved a 15% stock dividend, 0.15 shares of common stock (the “Stock Dividend”) per share of the Company’s issued and outstanding shares of common stock and per each common stock equivalent with dividend rights. The Board of Directors has fixed August 7, 2025 as the record date (the “Record Date”) for the Stock Dividend, and the Stock Dividend will be payable on August 21, 2025 to stockholders of record as of the Record Date.
