Equity [Abstract] |
Shareholders' (Deficit) Equity | 7. Shareholders’ (Deficit) Equity Preferred Stock As of March 31, 2026 and December 31, 2025, iMDx had 5,000,000 shares of preferred stock, no-par value, authorized. As of March 31, 2026 and December 31, 2025, iMDx had no shares of preferred stock issued and outstanding. Common Stock As of March 31, 2026 and December 31, 2025, iMDx had 230,000,000 shares of common stock, no-par value, authorized. As of March 31, 2026 and December 31, 2025, iMDx had 32,286,113 and 28,682,844 shares of common stock issued and outstanding, respectively. February 2025 Offering On February 10, 2025, the Company consummated a private placement of its securities to certain accredited investors for the issuance and sale of 7,536,706 shares of the Company's common stock and pre-funded warrants to purchase 3,069,926 shares of the Company's common stock, with an exercise price of $0.0001 per share. The purchase price for one common share was $2.05, and the purchase price for one pre-funded warrant was $2.05. Certain officers of the Company subscribed for 109,756 of the shares of common stock sold in the private placement, at a purchase price of $2.05 per share (see Note 9). The related securities purchase agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and the investors, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. A holder of the pre-funded warrants may not exercise any portion of such holder’s pre-funded warrants to the extent that the holder, together with its affiliates, would beneficially own more than 4.99% (or, at the election of the holder, 9.99%) of the Company’s outstanding shares of common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to the Company, the holder may increase the beneficial ownership limitation to up to 9.99% of the number of shares of common stock outstanding immediately after giving effect to the exercise. As of March 31, 2026, none of such pre-funded warrants have been exercised. Further, on February 10, 2025, the Company consummated a registered direct offering of its securities to certain investors for the issuance and sale of 3,609,755 shares of the Company's common stock, priced at-the-market under the rules of The Nasdaq Stock Market. The purchase price for one common share was $2.05. The related securities purchase agreement contains customary representations, warranties and agreements by the Company, indemnification obligations of the Company and the investors, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. The registered shares of common stock were offered by the Company pursuant to its shelf registration statement on Form S-3 (File No. 333-281159), which was filed with the SEC on August 1, 2024, and declared effective by the SEC on August 7, 2024, including the base prospectus contained therein, and a related prospectus supplement, dated February 7, 2025, filed with the SEC on February 10, 2025. The aggregate gross proceeds from the February 2025 Offering were approximately $29.1 million. After deducting offering expenses of $487,000, the resulting net proceeds were approximately $28.7 million. These net proceeds were inclusive of an investment from Bio-Rad (see Note 9), our global strategic partner. The Company is using the net proceeds received for general corporate purposes and working capital. February 2026 Offering On February 12, 2026, the Company consummated a registered direct offering of its securities to certain institutional investors for the issuance and sale of (i) 3,482,498 shares of the Company’s common stock, and (ii) pre-funded warrants to purchase up to 1,043,478 shares of common stock, pursuant to an effective shelf registration statement on Form S-3 (File No. 333-281159), a base prospectus and a related prospectus supplement, in each case filed with the SEC. The offering price was (i) $5.75 per share and (ii) $5.7499 per pre-funded warrant, which is the price of each share sold, minus the $0.0001 exercise price per pre-funded warrant. The pre-funded warrants may be exercised at any time until exercised in full, except that a holder (together with its affiliates) will not be entitled to exercise any portion of any pre-funded warrant, which, upon giving effect to such exercise would cause the aggregate number of shares of the Company’s common stock beneficially owned by the holder (together with its affiliates) to exceed 4.99% (or, upon election of the holder, 9.99%) of the number of shares of common stock outstanding immediately prior to or after giving effect to the exercise, subject to such holder’s rights under the pre-funded warrants to increase or decrease such percentage to another percentage not in excess of 9.99% of the number of shares of common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants upon at least 61 days’ prior notice from such holder to the Company. As of March 31, 2026, none of such pre-funded warrants have been exercised. The gross proceeds from the February 2026 Offering were approximately $26.0 million. After deducting placement agent fees and offering expenses of $1.4 million, the resulting net proceeds were approximately $24.6 million. These net proceeds were inclusive of an investment from Bio-Rad (see Note 9), our global strategic partner. The Company is using the net proceeds received primarily for general corporate purposes and working capital, including research and development in the transplantation category. Unregistered Restricted Stock Issuance During the three months ended March 31, 2026, the Company issued 4,636 shares of restricted common stock for a total fair value of $24,000 in connection with an ongoing investor relations consulting service arrangement. During the three months ended March 31, 2025, no such shares were issued. Common Stock Purchase Warrants As of March 31, 2026 and December 31, 2025, iMDx had common stock purchase warrants issued and outstanding of 760,866. During the three months ended March 31, 2026, no warrants were exercised or expired. As of March 31, 2026, the outstanding warrants had exercise prices ranging from $30.60 to $109.20 per share, are set to expire on various dates ranging from February 2027 to October 2029 and have a weighted average remaining life of 1.07 years. Certain warrants have “cashless exercise” provisions meaning that the value of a portion of warrant shares may be used to pay the exercise price rather than payment in cash, which may be exercised under any circumstances in the case of the Bank Warrants discussed below or, in the case of certain other warrants, only if a registration statement for the warrants and underlying shares of common stock is not effective under the Securities Act or a prospectus in the registration statement is not available for the issuance of shares upon the exercise of the warrants. All of the outstanding warrants meet the equity classification criteria and have been classified as equity, see Note 2, “Accounting for Warrants” for additional information. Bank Warrants In connection with a loan that matured in September 2022 from Silicon Valley Bank (the “Bank”), in February 2017, iMDx issued common stock purchase warrants to the Bank (the “2017 Bank Warrants”). The Bank was issued warrants to purchase 412 shares of iMDx common stock at an exercise price of $97.00 per share, through February 21, 2027. In March 2017, the Bank was issued warrants to purchase an additional 366 shares at an exercise price of $109.20 per share, through March 23, 2027. In October 2019, iMDx issued a common stock purchase warrant to the Bank (the “2019 Bank Warrant”) entitling the Bank to purchase 4,928 shares of iMDx common stock at an exercise price of $33.80 per share, through October 17, 2029. The Bank may elect to exercise the 2017 Bank Warrants and the 2019 Bank Warrant on a “cashless exercise” basis and receive a number of shares determined by multiplying the number of shares for which the Bank Warrant is being exercised by (A) the excess of the fair market value of the common stock over the applicable Warrant Price, divided by (B) the fair market value of the common stock. The fair market value of the common stock will be the last closing or sale price on a national securities exchange, interdealer quotation system, or over-the-counter market. These warrants meet the equity classification criteria and have been classified as equity. As of March 31, 2026, no Bank Warrants have been exercised. Pre-Funded Warrants In connection with an April 2024 offering (see Note 9, “Related Party Transactions – Financing Transactions”), t he Company issued pre-funded warrants to purchase 342,888 shares of common stock. In connection with the February 2025 Offering, the Company issued additional pre-funded warrants to purchase 3,069,926 shares of common stock. In connection with the February 2026 Offering, the Company issued additional pre-funded warrants to purchase 1,043,478 shares of common stock. For accounting purposes, the pre-funded warrants are equity-classified, contain no contingencies to exercise and are therefore considered outstanding for purposes of calculating basic earnings per share (see Note 2, “Net Loss Per Common Share”). As of March 31, 2026, none of such pre-funded warrants have been exercised.
