Collaborative Arrangement	10. Collaborative Arrangement On April 5, 2024, the Company entered into the Collaboration Agreement with Bio-Rad to collaborate in the development and the commercialization of RUO and IVD kitted transplant products using Bio-Rad’s ddPCR instruments and reagents. The Collaboration Agreement has a term of 10 years unless earlier terminated pursuant to customary termination provisions. The Collaboration Agreement provides that through the oversight of a joint steering committee comprised of representatives from both parties, the parties will collaborate on the development of (i) the Company’s series of GraftAssureIQ Transplant Monitoring Assays to measure and test the concentration of dd-cfDNA for RUO (the “RUO Assays”); and (ii) the Company’s GraftAssureDx Transplant Monitoring Assays that have received regulatory approval as an in vitro diagnostic device (the “IVD Kits”) for use on one or more Bio-Rad ddPCR instruments. Pursuant to the Collaboration Agreement, and toward the development of the RUO Assays and the IVD Kits, the Company will collect and screen samples, conduct feasibility testing and stability studies, and perform analytical validation, among other things; and Bio-Rad will supply its ddPCR instruments and platforms as well as manufacture and supply all consumables. Prior to the commercial launch of the RUO Assays, under the Collaboration Agreement, the parties will develop a plan to market and sell the RUO Assays. The Company will be responsible for the manufacture and supply of all RUO Assays, and Bio-Rad will supply to the Company Bio-Rad’s ddPCR instruments and reagents for use in commercializing the RUO Assays, which products will be purchased by the Company exclusively from Bio-Rad. The Company and Bio-Rad will be jointly responsible for co-promoting and co-marketing the RUO Assays within the United States and Germany (the “Territory”). The Company has the exclusive right to sell the RUO Assays in the Territory exclusively with the use of Bio-Rad ddPCR instruments and reagents. Bio-Rad will be responsible for promoting and marketing, and has the exclusive right to sell, the RUO Assays outside the Territory. For the sales of the RUO Assays in the Territory, the Company will pay to Bio-Rad a single digit royalty payment based on net sales. The Company will manufacture and supply the RUO Assays to Bio-Rad for resale outside the Territory. Additionally, the Collaboration Agreement provides Bio-Rad a 90-day exclusive negotiating period, post regulatory clearance, for the right to exclusively promote, market and sell IVD Kits worldwide subject to certain conditions. If and when such option is exercised, Bio-Rad will purchase additional shares of the Company’s common stock, no par value per share, at the then-current market price per share, up to a specified maximum aggregate purchase price, and the Company will manufacture and supply IVD Kits exclusively for Bio-Rad. See Note 9, “Related Party Transactions – Financing Transactions” for additional information. On November 8, 2024, iMDx and Bio-Rad entered into a binding Memorandum of Understanding (the “Memorandum”) in connection with the Collaboration Agreement. The Memorandum establishes additional activities (described below) to be performed by iMDx and Bio-Rad prior to the commercial launch of the RUO Assays specifically related to pilot study sites outside the Territory (the “Pilot Sites”). Pursuant to the Memorandum, iMDx (i) will setup commercialization of Pilot Sites to use the RUO Assays, (ii) may sell RUO Assays to Pilot Sites, (iii) will train and support the Pilot Sites on the use of the RUO Assays, and (iv) if iMDx receives any net sales from the sale of the RUO Assays to the Pilot Sites, then iMDx shall pay to Bio-Rad a royalty payment based on a percentage of such net sales under the terms and conditions of the Collaboration Agreement. In addition, pursuant to the Memorandum, Bio-Rad will evaluate commercialization efforts for the RUO Assays, which will include (i) supporting installation and training for Pilot Sites, and (ii) evaluating distribution of the RUO Assays to Pilot Sites. In May 2025, the Company sold its first RUO Assays to a Pilot Site (see Note 2, “Revenue Recognition – Kitted Products” for additional information). For the year ended December 31, 2025, the income statement amounts attributable to Bio-Rad transactions arising from the Collaboration Agreement, included cost of revenues, research and development expenses, sales and marketing expenses, general and administrative expenses, and interest expense, and in the aggregate have not been significant. See Note 9, “Related Party Transactions – Bio-Rad Transactions” for additional information. In addition, the Company is capitalizing RUO Assay related inventory costs (see Note 2, “Inventories” for additional information).
