Organization and Description of the Business	1. Organization and Description of the Business Insight Molecular Diagnostics Inc. (f/k/a Oncocyte Corporation) (“iMDx,” the “Company,” “we,” “our” or “us”), incorporated in 2009 in California, is a pioneering diagnostics technology company. Our mission is to expand access to novel molecular diagnostic testing, most immediately in the transplanted organ rejection testing category. Our current intellectual property portfolio comprises three general areas: 1) organ transplant, 2) oncology therapy selection, and 3) oncology therapy monitoring. Within these categories, we have developed or are in the process of developing laboratory developed tests (“LDTs”) that can be run at our Franklin, Tennessee laboratory, kitted research use only (“RUO”) tests, and in vitro diagnostic (“IVD”) kitted clinical tests that can be run by local labs. In June 2025, we changed our name from “Oncocyte Corporation” to “Insight Molecular Diagnostics Inc.” Our new trading symbol “IMDX” became effective on the Nasdaq Stock Market, LLC (“Nasdaq”) on June 18, 2025. In addition, in June 2025, we moved our headquarters from Irvine, California, to Nashville, Tennessee. Tennessee is home to our Clinical Laboratory Improvements Amendment (“CLIA”) certified lab and a growing hub for healthcare innovation. Business Risks Tariff policies and potential countermeasures could increase our costs and disrupt our global supply chain, which could negatively impact the results of our operations as well as our asset valuations and other fair value measurements. In addition, our business could be adversely impacted by other inflationary factors. The Company will continue to monitor these risks. Refer to Item 1A. “Risk Factors” included elsewhere in this Annual Report on Form 10-K for the year ended December 31, 2025 (this “Report”) for additional information about the risks that may impact our business. Liquidity iMDx has incurred operating losses and negative operating cash flows since its inception and had an accumulated deficit of $400.8 million as of December 31, 2025. iMDx expects to continue to incur operating losses and negative operating cash flows for the foreseeable future. Since its formation, iMDx has financed its operations primarily through the sale of shares of its common stock, convertible preferred stock and warrants to acquire common stock. As of December 31, 2025, iMDx had $11.6 million of cash and cash equivalents and $1.3 million in remaining restricted cash that started to be released in the third quarter of 2025 (see Note 6, “Office and Facilities Leases – Irvine Office Lease” for additional information). On February 12, 2026, we raised substantial additional capital as discussed below. On April 5, 2024, the Company entered into a global strategic partnership agreement with Bio-Rad Laboratories, Inc. (“Bio-Rad”) to collaborate in the development and the commercialization of RUO and IVD kitted transplant products for clinical use. On November 8, 2024, the Company and Bio-Rad entered into a memorandum of understanding with respect to such agreement to establish additional activities to be performed by each party pursuant to such agreement. See Note 10, “Collaborative Arrangements” for additional information. On February 10, 2025, the Company consummated a registered direct offering and concurrent private placement of its securities to certain accredited investors (the “February 2025 Offering”). The aggregate gross proceeds from the February 2025 Offering were approximately $29.1 million. After deducting offering expenses payable by the Company of $487,000, the resulting net proceeds were approximately $28.7 million. These net proceeds are inclusive of an investment from Bio-Rad (see Note 9), our aforementioned global strategic partner. The Company is using the net proceeds received for general corporate purposes and working capital. See Note 7, “Common Stock – February 2025 Offering” for additional information. On February 12, 2026, the Company consummated a registered direct offering of its securities to certain accredited investors (the “February 2026 Offering”). The gross proceeds from the February 2026 Offering were approximately $26.0 million. After deducting placement agent fees and offering expenses payable by the Company of $1.4 million, the resulting net proceeds were approximately $24.6 million. These net proceeds are inclusive of an investment from Bio-Rad (see Note 9), our aforementioned global strategic partner. The Company plans to use the net proceeds primarily for general corporate purposes, including but not limited to research and development in the transplantation category. See Note 13, “Subsequent Events – Registered Direct Offering” for additional information. In addition to general economic and capital market trends and conditions, iMDx’s ability to raise sufficient additional capital to finance its operations from time to time will depend on a number of factors specific to iMDx’s operations such as operating revenues and expenses, progress in our collaborative arrangement for the development and the commercialization of RUO and IVD kitted transplant products, progress in obtaining regulatory approval to distribute our products for clinical use, and progress in the development of, or in obtaining reimbursement coverage from Medicare for future laboratory tests that iMDx may develop or acquire. The unavailability or inadequacy of financing or revenues to meet future capital needs could force iMDx to modify, curtail, delay, or suspend some or all aspects of planned operations. Sales of additional equity securities could result in the dilution of the interests of iMDx's current stockholders. iMDx cannot assure that adequate long-term financing will be available on favorable terms, if at all. In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, we evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the consolidated financial statements included in this Report are issued. This evaluation initially does not take into consideration the potential mitigating effect of our plans that have not been fully implemented as of the date the consolidated financial statements included in this Report are issued. When substantial doubt exists under this methodology, we evaluate whether the mitigating effect of our plans sufficiently alleviates substantial doubt about our ability to continue as a going concern. The mitigating effect of our plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that such financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about our ability to continue as a going concern within one year after the date that such financial statements are issued. In performing this analysis, we excluded certain elements of our operating plan that cannot be considered probable. Although it is difficult to predict the Company’s liquidity requirements, based on the going concern evaluation discussed above, management believes that it will have sufficient cash to meet its projected operating requirements for at least the next twelve months following the issuance of these consolidated financial statements. The factors that previously raised substantial doubt about the Company's ability to continue as a going concern in the prior year were resolved in part as a result of the February 2026 Offering described above. Accordingly, management has concluded that substantial doubt does not exist about the Company's ability to continue as a going concern for a period of at least one year from the date of issuance of these consolidated financial statements. However, the Company anticipates that it will continue to generate operating losses and negative operating cash flows for the foreseeable future as it continues the development of its various programs and incurs additional costs associated with being a public company.
