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 Report, and in our Annual Report on Form 10-K for the year ended December 31, 2025, 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 $405.1 million as of March 31, 2026. 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 March 31, 2026, iMDx had $28.2 million of cash and cash equivalents and $1.2 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 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 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 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 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 aforementioned global strategic partner. The Company is using the net proceeds primarily for general corporate purposes and working capital, including research and development in the transplantation category. See Note 7, “Common Stock – February 2026 Offering” for additional information.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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. 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.

2. Summary of Significant Accounting Policies

Accounting Principles

The consolidated financial statements and accompanying notes are prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”).

Principles of Consolidation and Basis of Presentation

The unaudited condensed consolidated interim financial statements presented herein have been prepared in accordance with GAAP for financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. In accordance with those rules and regulations, certain information and footnote disclosures normally included in comprehensive audited consolidated financial statements may have been condensed or omitted. The consolidated balance sheet as of December 31, 2025 was derived from the audited consolidated financial statements at that date. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in iMDx’s Annual Report on Form 10-K for the year ended December 31, 2025. The accompanying unaudited condensed consolidated financial statements, in the opinion of management, include all adjustments of a normal recurring nature necessary for a fair presentation of iMDx’s financial condition and results of operations. The consolidated results of operations are not necessarily indicative of the results to be expected for any other interim period or for the entire year.

On January 31, 2020, with the acquisition of Insight Genetics, Inc. (“IGI”) through a merger with a newly incorporated wholly-owned subsidiary of iMDx (the “IGI Merger”) under the terms of an Agreement and Plan of Merger (the “IGI Merger Agreement”), IGI became a wholly-owned subsidiary of iMDx, and on that date iMDx began consolidating IGI’s operations and results with iMDx’s operations and results. See Note 3, “Business Combinations and Contingent Consideration Liabilities – Acquisition of IGI”

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

On April 15, 2021, with the acquisition of Chronix Biomedical, Inc. (“Chronix”) pursuant to an Agreement and Plan of Merger dated February 2, 2021, amended February 23, 2021, and amended and restated as of April 15, 2021 (as amended and restated, the “Chronix Merger Agreement”), by and among iMDx and CNI Monitor Sub, Inc., a Delaware corporation and wholly-owned subsidiary of iMDx, Chronix became a wholly-owned subsidiary of iMDx (the “Chronix Merger”), and on that date iMDx began consolidating Chronix’s operations and results with iMDx’s operations and results. See Note 3, “Business Combinations and Contingent Consideration Liabilities – Acquisition of Chronix.”

All material intercompany accounts and transactions have been eliminated in consolidation.

Reclassifications

Certain prior period amounts in the consolidated financial statements and notes to consolidated financial statements have been reclassified to conform to the current period presentation. These changes had no impact on the previously reported consolidated financial condition, results of operations or total cash flows.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and contingent assets and liabilities, at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates estimates which are subject to significant judgment, including, but not limited to, valuation methods used, assumptions requiring the use of judgment to prepare financial projections and forecasted financial information, timing of potential commercialization of acquired in-process intangible assets, applicable discount rates, probabilities of the likelihood of multiple outcomes of certain events related to contingent consideration, comparable companies or transactions, determination of fair value of the assets acquired and liabilities assumed (including those relating to contingent consideration), the carrying value of any goodwill and other intangibles and related impairments, assumptions related to going concern assessments, revenue recognition, allowances for credit losses, allocation of direct and indirect expenses, useful lives associated with long-lived intangible and other assets, key assumptions in operating and financing leases including incremental borrowing rates, loss contingencies, valuation allowances related to deferred income taxes, and assumptions used to value stock-based awards and other equity instruments. These assessments are made in the context of information reasonably available to iMDx. Actual results may differ materially from those estimates.

Segment Reporting

In accordance with ASC 280, Segment Reporting, iMDx’s management views its operations as one reportable segment that includes the research, development and commercialization of diagnostic tests, including molecular diagnostic testing products and services. See Note 11 for additional information.

Fair Value Measurements, Business Combinations and Contingent Consideration Liabilities

iMDx accounts for business combinations in accordance with ASC 805, which requires the purchase consideration transferred to be measured at fair value on the acquisition date in accordance with ASC 820, Fair Value Measurement. ASC 820 establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and expands on required disclosures about fair value measurement. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. ASC 820 describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:

•
Level 1 – Quoted prices in active markets for identical assets and liabilities.
•
Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted market prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

10

Table of Contents

INSIGHT MOLECULAR DIAGNOSTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

•
Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Such inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. Management estimates include certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs, including the entity’s own assumptions in determining fair value.

When a part of the purchase consideration consists of shares of iMDx common stock, iMDx calculates the purchase price attributable to those shares, a Level 1 security, by determining the fair value of those shares as of the acquisition date based on prices quoted on the principal national securities exchange on which the shares traded. iMDx recognizes estimated fair values of the tangible assets and identifiable intangible assets acquired, including any in-process research and development (“IPR&D”), and liabilities assumed, including any contingent consideration, as of the acquisition date. Goodwill is recognized as any amount of excess consideration transferred over the fair value of the tangible and identifiable intangible assets acquired net of the liabilities assumed. ASC 805 precludes the recognition of an assembled workforce as an asset, effectively subsuming any assembled workforce value into goodwill.

In determining fair value, iMDx utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, and also considers counterparty credit risk in its assessment of fair value. As of March 31, 2026 and December 31, 2025, iMDx had no financial assets recorded at fair value on a recurring basis, except for money market funds. These assets are reported as cash equivalents and are measured at fair value using the period-end quoted market prices as a Level 1 input. iMDx's financial liabilities recorded at fair value on a recurring basis include contingent consideration, and are discussed below.

The carrying amounts of cash and cash equivalents, restricted cash, net accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximate fair values because of the short-term nature of these items.

In accordance with GAAP, from time to time, iMDx measures certain assets at fair value on a nonrecurring basis. iMDx reviews the carrying value of intangibles and other long-lived assets for indications of impairment at least annually. Refer to related discussions of impairments below.

Contingent Consideration Liabilities

Certain of iMDx’s asset and business acquisitions involved the potential for future payment of consideration to third-parties and former selling shareholders in amounts determined as a percentage of future net revenues generated, or upon attainment of revenue milestones, from laboratory services or tests, as applicable, or annual minimum royalties to certain licensors, as provided in the applicable agreements. The fair value of such liabilities is determined using unobservable inputs. These inputs include the estimated amount and timing of projected cash flows and the risk-adjusted discount rate used to present value the cash flows. These obligations are referred to as contingent consideration, which are carried at fair value based on Level 3 inputs on a recurring basis.

ASC 805 requires that contingent consideration be estimated and recorded at fair value as of the acquisition date as part of the total consideration transferred. Contingent consideration is an obligation of the acquirer to transfer additional assets or equity interests to the selling shareholders in the future if certain future events occur or conditions are met, such as the attainment of product development milestones. Contingent consideration also includes additional future payments to selling shareholders based on achievement of components of earnings, such as “earn-out” provisions or percentage of future revenues, including royalties paid to the selling shareholders based on a percentage of certain revenues generated.

The fair value of contingent consideration after the acquisition date is reassessed by iMDx as changes in circumstances and conditions occur, with the subsequent change in fair value recorded in the consolidated statements of operations. Changes in key assumptions can materially affect the estimated fair value of contingent consideration liabilities and, accordingly, the resulting gain or loss that iMDx records in its consolidated financial statements. See Note 3 for a full discussion of these liabilities and additional Level 3 fair value disclosures.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Cash, Cash Equivalents and Restricted Cash

iMDx considers all highly liquid securities with original maturities of three months or less when purchased to be cash equivalents. For the periods presented, iMDx’s cash equivalents are comprised of investments in AAA rated money market funds that invest in first-tier only securities, which primarily include domestic commercial paper and securities issued or guaranteed by the U.S. government or its agencies. Restricted cash balances, as reported in the consolidated balance sheets, relate to a bank letter of credit required under an office lease arrangement, see Note 6 for additional information.

For cash flow reporting purposes, the Company combines the reported balance sheet amounts from cash and cash equivalents with restricted cash (current and noncurrent). Accordingly, as of March 31, 2026 and 2025, the aggregate amount of such ending balances were $29.4 million and $32.7 million, respectively, as presented in the consolidated statements of cash flows.

Investments in Privately Held Companies

iMDx evaluates whether investments held in common stock of other companies require consolidation of the company under, first, the variable interest entity (“VIE”) model, and then under the voting interest model in accordance with accounting guidance for consolidations under ASC 810-10. If consolidation of the entity is not required under either the VIE model or the voting interest model, iMDx determines whether the equity method of accounting should be applied in accordance with ASC 323, Investments – Equity Method and Joint Ventures. The equity method applies to investments in common stock or in-substance common stock if iMDx exercises significant influence over, but does not control, the entity, where significant influence is typically represented by ownership of 20% or more, but less than majority ownership, of the voting interests of a company. iMDx initially records equity method investments at fair value on the date of the acquisition with subsequent adjustments to the investment balance based on iMDx’s pro rata share of earnings or losses from the investment.

iMDx’s first product for commercial release was a proprietary treatment stratification test called DetermaRx that identified which patients with early-stage non-small cell lung cancer may benefit from chemotherapy, resulting in a significantly higher, five-year survival rate. Beginning in September 2019 through February 23, 2021, iMDx held a 25% equity interest in Razor Genomics, Inc. (“Razor”), a privately held company, that had developed and licensed to iMDx the lung cancer treatment stratification laboratory test that iMDx was commercializing as DetermaRx. On February 24, 2021, iMDx completed the purchase of all the remaining issued and outstanding shares of common stock of Razor. As a result of the purchase of the Razor common stock, iMDx became the sole shareholder of Razor. On December 15, 2022, the Company entered into a Stock Purchase Agreement (the “Razor Stock Purchase Agreement”) with Dragon Scientific, LLC, a Delaware limited liability company (“Dragon”), and Razor. Pursuant to the Razor Stock Purchase Agreement, iMDx agreed to sell to Dragon, 3,188,181 shares of common stock of Razor, which constituted approximately 70% of the issued and outstanding equity interests of Razor on a fully-diluted basis, and transfer to Razor all of the assets and liabilities related to DetermaRx (the “Razor Sale Transaction”). On February 16, 2023, iMDx completed the Razor Sale Transaction (the “Razor Closing”). In connection with the Razor Closing, iMDx transferred to Razor all of the assets and liabilities related to DetermaRx. While no monetary consideration was received for the sale of 70% of the equity interests of Razor, the transaction allowed the Company to eliminate all development and commercialization costs with respect to DetermaRx. Following the Razor Closing, iMDx continues to own 1,366,364 shares of common stock of Razor, which constitutes approximately 30% of the issued and outstanding equity interests of Razor on a fully-diluted basis, however, the remaining common stock held is accounted for at historical cost less impairment, which is currently zero.

Inventories

Inventories include raw materials, work-in-process and finished goods and are valued at the lower of cost or net realizable value. In September 2024, the Company began to capitalize certain RUO inventory costs in connection with its collaboration arrangement with Bio-Rad to develop and commercialize its GraftAssureIQ RUO kitted tests and eventual GraftAssureDx IVD kitted transplant testing products. See Note 10, “Collaborative Arrangements” for additional information. As of March 31, 2026, inventories were comprised of RUO raw materials of $319,000 and finished goods of $63,000. As of December 31, 2025, inventories were comprised of RUO raw materials of $368,000 and finished goods of $78,000.

Assets Held for Sale

In accordance with ASC subtopic 360-10, Property, Plant, and Equipment, assets and liabilities are classified as held for sale when all of the following criteria for a plan of sale have been met: (1) management, having the authority to approve the action, commits to a plan to sell the assets; (2) the assets are available for immediate sale, in their present condition, subject only to terms that are usual and customary for sales of such assets; (3) an active program to locate a buyer and other actions required to complete the plan to sell the assets have been initiated; (4) the sale of the assets is probable and is expected to be completed within one year; (5) the assets are being actively marketed for a price that is reasonable in relation to their current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or the plan will be withdrawn. When all of these criteria have been met, the assets and liabilities are classified as held for sale in the consolidated balance sheet. Assets classified as held for sale are reported at the lower of their carrying value or fair value less costs to sell. Depreciation and amortization of assets ceases upon designation as held for sale.

Historically, the Company has entered into agreements to sell certain laboratory equipment. As a result, the Company classified the equipment as held for sale current assets in the consolidated balance sheet, when all the criteria of ASC 360-10 had been met. As of March 31, 2026 and December 31, 2025, the Company had no assets held for sale.

Property and Equipment

Machinery and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the assets, generally over a period of 3 to 10 years. For equipment purchased under financing leases, iMDx amortizes the equipment based on the shorter of the useful life of the equipment or the term of the lease, ranging from 3 to 5 years, depending on the nature and classification of the financing lease (see Note 6). Maintenance and repairs are expensed as incurred whereas significant renewals and betterments are capitalized. When assets are retired or otherwise disposed of, the cost and the related accumulated depreciation or amortization are removed from the respective accounts and any resulting gain or loss is reflected in the results of operations.

Construction in progress, comprised primarily of leasehold improvements under construction, is not depreciated or amortized until the underlying asset is placed into service.

Intangible Assets

In accordance with ASC 350, Intangibles – Goodwill and Other, IPR&D projects acquired in a business combination that are not complete as of the acquisition date are capitalized and accounted for as indefinite-lived intangible assets until completion or abandonment of the related research and development efforts. Upon successful completion of the project, the capitalized amount is amortized over its estimated useful life. If a project is abandoned, all remaining capitalized amounts are written off immediately. iMDx considers various factors and risks for potential impairment of IPR&D assets, including the current legal and regulatory environment and the competitive landscape. Adverse clinical trial results, significant delays or inability to obtain local coverage determination (“LCD”) from the Centers for Medicare and Medicaid Services (“CMS”) for Medicare reimbursement for a diagnostic test, the inability to bring a diagnostic test to market and the introduction or advancement of competitors’ diagnostic tests could result in partial or full impairment of the related intangible assets. Consequently, the eventual realized value of the IPR&D project may vary from its fair value at the date of acquisition, and IPR&D impairment charges may occur in future periods. During the period between completion or abandonment, the IPR&D assets will not be amortized but will be tested for impairment on an annual basis and between annual tests if iMDx becomes aware of any events occurring or changes in circumstances that would indicate a reduction in the fair value of the IPR&D projects below their respective carrying amounts.

iMDx does not have intangible assets with indefinite useful lives reported in the consolidated balance sheets. The previously acquired IPR&D intangible assets were fully impaired as of December 31, 2025. See Note 5 for additional information.

INSIGHT MOLECULAR DIAGNOSTICS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

In accordance with ASC 350, we review and evaluate our intangible assets for impairment whenever events or changes in circumstances indicate that we may not recover their net book value. When applicable, we test for impairment on an annual basis in the fourth quarter of each year, and between annual tests, if indicators of potential impairment exist, using a fair-value approach. We typically use an income method to estimate the fair value of these assets, which is based on forecasts of the expected future cash flows attributable to the respective assets. Significant estimates and assumptions inherent in the valuations reflect a consideration of other marketplace participants and include the amount and timing of future cash flows (including expected growth rates). Estimates utilized in the projected cash flows include consideration of macroeconomic conditions, overall category growth rates, competitive activities, cost containment and margin expansion, Company business plans, the underlying product or technology life cycles, economic barriers to entry, and the discount rate applied to the cash flows. Unanticipated market or macroeconomic events and circumstances may occur, which could affect the accuracy or validity of the estimates and assumptions.

When applicable, goodwill represents the excess of the purchase price over the fair value of net identifiable assets and liabilities. Goodwill, similar to IPR&D, is not amortized but is tested for impairment at least annually, or if circumstances indicate that it is more-likely-than-not that the carrying value of the associated reporting unit exceeds its fair value. Qualitative factors considered in this assessment include industry and market conditions, overall financial performance, and other relevant events and factors affecting iMDx’s business. Based on the qualitative assessment, if it is determined that the fair value of goodwill is more-likely-than-not to be less than its carrying amount, the fair value of a reporting unit will be calculated and compared with its carrying amount and an impairment charge will be recognized for the amount that the carrying value exceeds the fair value. iMDx continues to operate in one segment (see Note 11) and is considered to be the sole reporting unit and, therefore, goodwill will be tested for impairment at the enterprise level, when applicable.

Long-Lived Intangible Assets

Long-lived intangible assets subject to amortization are stated at acquired cost, less accumulated amortization. iMDx amortizes intangible assets not considered to have an indefinite useful life using the straight-line method over their estimated period of benefit, which generally ranges from 1 to 9 years. Each reporting period, we evaluate the estimated remaining useful life of intangible assets and assess whether events or changes in circumstances warrant a revision to the remaining period of amortization or indicate that impairment exists. iMDx's long-lived intangible assets consisted of acquired customer relationships, which were fully amortized in 2025. See Note 5 for additional information.

Impairment of Long-Lived Assets

iMDx’s long-lived assets consist primarily of right-of-use assets for operating and financing leases, and machinery and equipment. If e vents or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable and the expected undiscounted future cash flows attributable to the asset are less than the carrying amount of the asset, an impairment loss, equal to the excess of the carrying value of the asset over its fair value, is recorded.

Leases

iMDx accounts for leases in accordance with ASC 842, Leases. iMDx determines if an arrangement is a lease at inception. Leases are classified as either financing or operating, with classification affecting the pattern of expense recognition in the consolidated statements of operations. iMDx accounts for the lease and non-lease components as a single lease component. iMDx recognizes right-of-use (“ROU”) assets and lease liabilities for leases with terms greater than twelve months in the consolidated balance sheets. ROU assets represent the right to use an underlying asset during the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most leases do not provide an implicit rate, iMDx uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. iMDx uses the implicit rate when it is readily determinable. The ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that iMDx will exercise that option. Operating lease expense and financing lease amortization expense are recognized on a straight-line basis over the lease term. Operating leases include ROU office lease assets and related lease liabilities, current and long-term, in the consolidated balance sheets. Financing leases include ROU machinery and equipment and related financing lease liabilities, current and long-term, in the consolidated balance sheets (see “Property and Equipment” above for more information). iMDx discloses the amortization of operating lease ROU assets and the related repayments of lease obligations as a net amount in the consolidated statements of cash flows. iMDx has entered into various operating and financing leases in accordance with ASC 842 as further discussed in Note 6.

Accounting for Warrants

iMDx determines the accounting classification of warrants it issues, as either liability or equity classified, by first assessing whether the warrants meet liability classification in accordance with ASC 480-10, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity, then in accordance with ASC 815-40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock. Under ASC 480, warrants are considered liability classified if the warrants are mandatorily redeemable, obligate iMDx to settle the warrants or the underlying shares by paying cash or other assets, or for warrants that must or may require settlement by issuing a variable number of shares. If warrants do not meet liability classification under ASC 480, iMDx assesses the requirements under ASC 815-40, which states that contracts that require or may require the issuer to settle the contract for cash are liabilities recorded at fair value, irrespective of the likelihood of the transaction occurring that triggers the net cash settlement feature. This liability classification guidance also applies to financial instruments that may require cash or other form of settlement for transactions outside of the company’s control and, in which the form of consideration to the warrant holder may not be the same as to all other shareholders in connection with the transaction. However, if a transaction is not within the company’s control but the holder of the financial instrument can solely receive the same type or form of consideration as is being offered to all the shareholders in the transaction, then equity classification of the financial instrument is not precluded, if all other applicable equity classification criteria are met.

After all relevant assessments, iMDx concludes whether the warrants are classified as liability or equity. Liability classified warrants require fair value accounting at issuance and subsequent to initial issuance with all changes in fair value after the issuance date recorded in the consolidated statements of operations. Equity classified warrants only require fair value accounting at issuance with no changes recognized subsequent to the issuance date. Based on the above guidance and, among other factors, the fact that our warrants cannot be cash settled under any circumstance but require share settlement, all of our outstanding warrants meet the equity classification criteria and have been classified as equity. See Note 7 for details about our outstanding warrants.

Revenue Recognition

Pursuant to ASC 606, Revenue from Contracts with Customers, revenues are recognized when control of goods or services is transferred to customers, in an amount that reflects the consideration iMDx expects to be entitled to in exchange for those goods or services. ASC 606 provides for a five-step model that includes:

(i)
identifying the contract with a customer,
(ii)
identifying the performance obligations in the contract,
(iii)
determining the transaction price,
(iv)
allocating the transaction price to the performance obligations, and
(v)
recognizing revenue when, or as, an entity satisfies a performance obligation.

iMDx determines transaction prices based on the amount of consideration we expect to receive for transferring the promised goods or services in the contract. Consideration may be fixed, variable, or a combination of both. The Company considers any constraints on the variable consideration and includes in the transaction price variable consideration to the extent it is deemed probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

The following table presents consolidated revenues by type:

|  | Three Months Ended March 31, |
|  | 2026 |  |  | 2025 |
|  | (In thousands) |
Laboratory Services |  | $ | 32 |  |  | $ | 2,138 |

Laboratory Services

Revenues recognized include Laboratory Services performed by iMDx for life sciences customers, including testing for biomarker discovery, assay design and development, clinical trial support, and a broad spectrum of biomarker tests. These Laboratory Services are generally performed under individual scope of work (“SOW”) arrangements or license agreements (together with SOW the “Laboratory Services Agreements”) with specific deliverables defined by the customer. Laboratory Services are performed on a (i) time and materials basis or (ii) per test completed basis. Upon completion of the service to the customer in accordance with a Laboratory Services Agreement, iMDx has the right to bill the customer for the agreed upon price (either on a per test or per deliverable basis) and recognizes Laboratory Service revenue at that time. Depending on the Laboratory Services Agreement, iMDx may identify the services offered as a single performance obligation, or identify the processing of test samples as a separate performance obligation (considered a series) within license agreements.

Completion of the service and satisfaction of the performance obligation is typically evidenced by acknowledgment of completed services, and access to the report or test made available to the customer or any other form or applicable manner of delivery defined in the Laboratory Services Agreements. However, for certain SOWs under which work is performed pursuant to the customer’s highly customized specifications, iMDx has the enforceable right to bill the customer for work completed, rather than upon completion of the SOW. For those SOWs, iMDx recognizes revenue over a period during which the work is performed using a formula that accounts for expended efforts, generally measured in labor hours, as a percentage of total estimated efforts for the completion of the SOW. As performance obligations are satisfied under the Laboratory Services Agreements, any amounts earned as revenue and billed to the customer are included in accounts receivable. Any revenues earned but not yet billed to the customer as of the date of iMDx’s consolidated financial statements are recorded as contract assets and are included in other current assets as of the financial statement date. Amounts recorded in contract assets are reclassified to accounts receivable in iMDx’s consolidated balance sheets when the customer is invoiced according to the billing schedule in the contract.

As of March 31, 2026 and December 31, 2025 and 2024, iMDx had gross accounts receivable from Laboratory Services customers of $159,000, $1.1 million and $1.6 million, respectively.

Allowance for Credit Losses

iMDx establishes an allowance for credit losses based on the evaluation of the collectability of its Laboratory Services accounts receivables after considering a variety of factors, including the length of time receivables are past due, significant events that may impair the customer’s ability to pay, such as a bankruptcy filing or deterioration in the customer’s operating results or financial condition, reasonable and supportable forecast that affect the collectability of the reported amount, and historical experience. If circumstances related to customers change, estimates of the recoverability of receivables would be further adjusted. iMDx continuously monitors collections and payments from customers and maintains a provision for estimated credit losses and uncollectible accounts, if any, based upon its historical experience and any specific customer collection issues that have been identified. Amounts determined to be uncollectible are written off against the credit loss reserve accounts. As of March 31, 2026 and December 31, 2025 and 2024, iMDx had an allowance for credit losses of $2,000, $11,000 and $16,000, respectively, related to Laboratory Services.

Kitted Products

Revenues recognized include our GraftAssureIQ RUO kitted tests, which are clearly labeled and intended for research purposes. GraftAssureIQ is a transplant monitoring assay to measure the donor-derived cell-free DNA (“dd-cfDNA”) molecular biomarker. iMDx recognizes revenue to depict the transfer of goods to a customer at an amount that reflects the consideration which it expects to receive for providing those goods. As of March 31, 2026 and December 31, 2025, iMDx ha d no accounts receivable fr om Kitted Products customers. See Note 10, “Collaborative Arrangements” for additional Kitted Products information.

Licensing

Revenues that may be recognized include licensing revenue derived from agreements with customers for exclusive rights to market iMDx’s proprietary testing technology. Under the agreements, iMDx grants exclusive rights to certain trademarks and technology of iMDx for the purpose of marketing iMDx’s tests within a defined geographic territory. A license agreement may specify milestone deliverables or performance obligations, for which iMDx recognizes revenue when its licensee confirms the completion of iMDx’s performance obligation. A licensing agreement may also include ongoing sales support from iMDx and typically includes non-refundable licensing fees and per-test Laboratory Services revenues discussed above, for which iMDx treats the licensing of the technology, trademarks, and ongoing support as a single performance obligation satisfied by the passage of time over the term of the agreement.

Disaggregation of Revenues and Concentrations of Credit Risk

See Note 11, “Segment Reporting” for additional information about geographical revenues and long-lived tangible assets.

Financial instruments that potentially subject the Company to concentrations of credit risk are cash and cash equivalents and accounts receivable. The Company places its cash equivalents primarily in highly rated money market funds. Cash and cash equivalents are also invested in deposits with certain financial institutions and may, at times, exceed federally insured limits. The Company has not experienced any significant losses on its deposits of cash and cash equivalents.

One customer individually represented approximately 100% of accounts receivable as of March 31, 2026. One customer individually represented approximately 100% of accounts receivable as of December 31, 2025. No other customers individually represented greater than ten percent of total accounts receivable.

The Company has a concentration in the volume of business transacted with Bio-Rad, its global strategic partner. In 2024, the Company entered into an 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, pursuant to which it is dependent on Bio-Rad with respect to many of its ongoing operations and future target performance. In addition, Bio-Rad is a significant investor in the Company's common stock. See Note 9, “Related Party Transactions” and Note 10, “Collaborative Arrangements” for additional information.

Cost of Revenues

Cost of revenues generally consists of cost of materials, direct labor including benefits, bonus and stock-based compensation, equipment and infrastructure expenses, clinical sample related costs associated with performing Laboratory Services, providing deliverables according to our licensing agreements, license fees due to third-parties, and Kitted Products inventory costs (see “Inventories” above) and royalties based on net product sales. Infrastructure expenses include depreciation of laboratory equipment, allocated rent costs, leasehold improvements, and allocated information technology costs for operations at iMDx’s CLIA-certified laboratory in Tennessee. Costs associated with generating service revenue are recorded as the tests or services are performed regardless of whether revenue was recognized. Royalties or revenue share payments for licensed technology calculated as a percentage of revenues generated using the associated technology, or from product sales, are recorded as expenses at the time the related revenues are recognized. Certain cost of revenues are attributed to our global strategic collaboration arrangement with Bio-Rad for commercializing our kitted test products. See Note 10, “Collaborative Arrangements” for additional information.

Research and Development Expenses

Research and development expenses are comprised of costs incurred to develop technology, which include salaries and benefits, stock-based compensation, laboratory expenses (including reagents and supplies used in research and development laboratory work), consumed kitted products, clinical trial expenses, infrastructure expenses (including depreciation expense and allocated facility occupancy costs), and contract services and other outside costs. Indirect research and development expenses are allocated primarily based on headcount, as applicable, and include rent and utilities, common area maintenance, telecommunications, property taxes and insurance. Research and development costs are expensed as incurred. Certain research and development expenses are attributed to our global strategic collaboration arrangement with Bio-Rad for commercializing our kitted test products. See Note 10, “Collaborative Arrangements” for additional information.

Sales and Marketing Expenses

Sales and marketing expenses consist primarily of personnel costs and related benefits, including stock-based compensation, trade show expenses, branding and positioning expenses, free kitted products, travel expenses, and consulting fees. Sales and marketing expenses also include indirect expenses for applicable overhead allocated based on headcount, and include allocated costs for rent and utilities, common area maintenance, depreciation expense, telecommunications, property taxes and insurance. During the three months ended March 31, 2026 and 2025, iMDx’s total advertising expenses were $135,000 and $91,000, respectively. Certain sales and marketing expenses are attributed to our global strategic collaboration arrangement with Bio-Rad for commercializing our kitted test products. See Note 10, “Collaborative Arrangements” for additional information.

General and Administrative Expenses

General and administrative expenses consist primarily of compensation and related benefits, including stock-based compensation, for executive and corporate personnel, professional and consulting fees, travel expenses, rent and utilities, common area maintenance, depreciation expense, telecommunications, property taxes and insurance. Certain general and administrative expenses are attributed to our global strategic collaboration arrangement with Bio-Rad for commercializing our kitted test products.

Stock-Based Compensation

iMDx recognizes compensation expense related to employee, Board of Director and other non-employee option grants and restricted stock grants in accordance with ASC 718, Compensation – Stock Compensation.

iMDx estimates the fair value of stock-based payment awards on the grant date and recognizes the resulting fair value over the requisite service period, which is generally a three or four-year vesting period. For stock-based awards that vest only upon the attainment of one or more performance goals set by iMDx at the time of the grant (sometimes referred to as milestone vesting), compensation cost is recognized if and when iMDx determines that it is probable that the performance condition or conditions will be, or have been, achieved. iMDx uses the Black-Scholes option pricing model for estimating the fair value of time-based options granted under iMDx’s equity plan. The fair value of each restricted stock unit (“RSU”) or award (“RSA”) is determined by the product of the number of units or shares granted and the grant date market price of the underlying common stock. iMDx has elected to treat stock-based payment awards with graded vesting schedules and time-based service conditions as a single award and recognizes stock-based compensation ratably on a straight-line basis over the requisite service period. Options have a maximum contractual term of ten years. Forfeitures are accounted for as they occur. See Note 8 for additional information.

The Black-Scholes option pricing model requires iMDx to make certain assumptions including the expected option term, the expected volatility, the risk-free interest rate and the dividend yield. The expected term of employee stock options represents the weighted average period that the stock options are expected to remain outstanding. iMDx estimates the expected term of options granted based on its own experience. iMDx estimates the expected volatility using its own stock price volatility for a period equal to the expected term of the options. The risk-free interest rate assumption is based upon observed interest rates on the United States government securities appropriate for the expected term of iMDx’s stock options. The dividend yield assumption is based on iMDx’s history and expectation of dividend payouts. iMDx has never declared or paid any cash dividends on its common stock, and iMDx does not anticipate paying any cash dividends in the foreseeable future.

All excess tax benefits and tax deficiencies from stock-based compensation awards accounted for under ASC 718 are recognized as income tax benefit or expense, respectively, in the consolidated statements of operations. An excess income tax benefit arises when the tax deduction of a stock-based award for income tax purposes exceeds the compensation cost recognized for financial reporting purposes and, a tax deficiency arises when the compensation cost exceeds the tax deduction. Because iMDx has a full valuation allowance for all periods presented (see “Income Taxes” below), there was no impact to iMDx's consolidated statements of operations for any excess tax benefits or deficiencies, as any excess benefit or deficiency would be offset by the change in the valuation allowance. iMDx does not recognize deferred income taxes for incentive stock option compensation expense and records a tax deduction only when a disqualified disposition has occurred.

Retirement Plan

iMDx has an employee savings and retirement plan under Section 401(k) of the Internal Revenue Code. The plan is a defined contribution plan in which eligible employees may elect to have a percentage of their compensation contributed to the plan, subject to certain guidelines issued by the Internal Revenue Service. During the three months ended March 31, 2026 and 2025, iMDx’s total contributions to the plan were $108,000 and $77,000, respectively.

Collaborative Arrangements

The Company analyzes its collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements, which includes determining whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. To the extent that the arrangement falls within the scope of ASC 808, the Company assesses whether the payments between the Company and its collaboration partner fall within the scope of other accounting literature. If the Company concludes that payments from the collaboration partner to the Company would represent consideration from a customer, the Company accounts for those payments within the scope of ASC 606. However, if the Company concludes that its collaboration partner is not a customer for certain activities and associated payments, the Company presents such payments as a reduction of the related expense, based on where the Company presents the underlying expense. See Note 10, “Collaborative Arrangements” for additional information.

Foreign Currency Gains and Losses

Foreign currency gains and losses primarily relate to our Chronix subsidiary in Germany, where the local currency is the functional currency. Assets and liabilities are translated from the foreign currency into U.S. dollars at the exchange rates in effect at the balance sheet date, while income and expenses are translated at the weighted average exchange rates for the period. The net effects of translating the foreign currency financial statements are included in the consolidated shareholders’ (deficit) equity as a component of accumulated other comprehensive income or loss. Gains and losses for all transactions denominated in a currency other than the U.S. dollar are recognized in the period incurred and included in the consolidated statements of operations as a component of other income or expense.

Other Income and Expenses

Other income and expenses are primarily comprised of interest income, interest expense, and foreign currency gains and losses. Interest income is earned from money market funds we hold for capital preservation. Interest expense is primarily incurred from our financing lease obligations (see Note 6).

Income Taxes

iMDx and its subsidiaries will file a consolidated U.S. federal income tax return and combined California state return for the year ending December 31, 2026. iMDx accounts for income taxes in accordance with ASC 740, Income Taxes, which prescribes the use of the asset and liability method, whereby deferred tax asset or liability account balances are calculated at the balance sheet date using current tax laws and rates in effect. The provision for income taxes for interim periods is determined using an estimated annual effective tax rate in accordance with ASC 740-270, Income Taxes, Interim Reporting. The effective tax rate may be subject to fluctuations during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as valuation allowances against deferred tax assets, the recognition or de-recognition of tax benefits related to uncertain tax positions, if any, and changes in or the interpretation of tax laws in jurisdictions where iMDx conducts business.

iMDx did not record any provision or benefit for income taxes for the three months ended March 31, 2026 and 2025, as iMDx had a full valuation allowance for the periods presented.

Valuation allowances are established when necessary to reduce deferred tax assets when it is more-likely-than-not that a portion or all of the deferred tax assets will not be realized. iMDx’s judgments regarding future taxable income may change over time due to changes in market conditions, changes in tax laws, tax planning strategies or other factors. If iMDx’s assumptions and consequently its estimates change in the future, the valuation allowance may be increased or decreased, which may have a material impact on iMDx’s consolidated statements of operations. iMDx established a full valuation allowance for all periods presented due to the uncertainty of realizing future tax benefits from its net operating loss carry-forwards and other deferred tax assets.

The guidance also prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not sustainable upon examination by taxing authorities. iMDx will recognize accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of March 31, 2026 and December 31, 2025. iMDx is not aware of any uncertain tax positions that could result in significant additional payments, accruals, or other material deviation as of March 31, 2026. iMDx is currently unaware of any tax issues under review. As of March 31, 2026 and December 31, 2025, iMDx had unrecognized tax benefits totaling $1.6 million.

On July 4, 2025, the U.S. enacted H.R. 1, “A bill to provide for reconciliation pursuant to Title II of H. Con. Res. 14,” commonly referred to as the One Big Beautiful Bill. Changes in tax laws may affect recorded deferred tax assets and deferred tax liabilities and iMDx’s effective tax rate in the future. iMDx continues to evaluate the impacts the new legislation will have on the consolidated financial statements. As a result of the enactment of H.R. 1, iMDx anticipates an impact to the deferred tax asset related to the full expensing of domestic research and experimental expenditures in 2025 and 2026. iMDx does not expect this change to result in any material impact to its overall tax expense.

The American Rescue Plan Act (“ARPA”) was signed on March 11, 2021. One of the provisions of the ARPA included a modification to the provision limiting the deductibility of executive compensation expense, expanding the definition of covered employees to include the top five highest compensated employees beyond the CEO, CFO and three highest paid officers. The provision was further modified by H.R. 1, which made the provision applicable to publicly traded companies and all members of their controlled group (as opposed to members of the affiliated group, as prescribed under prior law). All changes are effective for tax years beginning after December 31, 2026. While iMDx does not believe that these modifications will have a material impact on its income tax provision currently, iMDx will continue to monitor this provision.

Net Loss Per Common Share

Basic loss per share is computed by dividing the net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Basic weighted average shares outstanding includes the effects of pre-funded warrants that were issued in April 2024, February 2025 and February 2026 (see Note 7, “Common Stock Purchase Warrants” for additional information). Diluted loss per share is computed by dividing the net loss applicable to common stockholders by the weighted average number of common shares outstanding plus the number of additional common shares that would have been outstanding if all dilutive potential common shares had been issued, using the treasury stock method or the if-converted method, as applicable. Potential common shares are excluded from the computation if their effect is antidilutive.

For the three months ended March 31, 2026 and 2025, all common stock equivalents are antidilutive because iMDx reported a net loss. The following table presents the antidilutive potential common shares:

Recent Accounting Pronouncements

Not Yet Adopted

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, to address investor requests for more detailed information about certain types of reported costs and expenses. The amendments in this Update require disclosure, in the notes to financial statements, at each interim and annual reporting period an entity: 1) disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, and (d) intangible asset amortization included in each expense caption presented on the face of the income statement within continuing operations; 2) include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements; 3) disclose a qualitative description of the amounts remaining that are not separately disaggregated quantitatively; and 4) disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments in this Update should be applied either prospectively or retrospectively, and are effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. Management is currently evaluating the impact that the amendments in this Update will have on the Company’s financial statement disclosures. The adoption of this new standard will not have an impact on the Company’s consolidated balance sheets and consolidated statements of operations, comprehensive loss, shareholders' (deficit) equity and cash flows.

In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, to modernize the accounting for internal-use software costs. The amendments in this Update remove all references to prescriptive and sequential software development stages (referred to as “project stages”). Therefore, an entity is required to start capitalizing software costs when both of the following occur: 1) management has authorized and committed to funding the software project, and 2) it is probable that the project will be completed and the software will be used to perform the function intended (the “probable-to-complete recognition threshold”). In evaluating the probable-to-complete recognition threshold, an entity is required to consider whether there is significant uncertainty associated with the development activities of the software. In addition, the amendments supersede the website development costs guidance and incorporate the recognition requirements for website-specific development costs from Subtopic 350-50 into Subtopic 350-40. The amendments in this Update are effective for annual periods beginning after December 15, 2027, and interim periods within those annual periods, with early adoption permitted. The amendments may be applied prospectively, using a modified transition approach, or retrospectively. Management is currently evaluating the impact that the amendments in this Update will have on the Company’s consolidated balance sheets and consolidated statements of operations, comprehensive loss, shareholders' (deficit) equity and cash flows, and related disclosures.

3. Business Combinations and Contingent Consideration Liabilities

Acquisition of IGI

On January 31, 2020 (the “IGI Merger Date”), iMDx completed its acquisition of IGI pursuant to the IGI Merger Agreement. iMDx determined there were two types of contingent consideration in connection with the IGI Merger, the Milestone Contingent Consideration and the Royalty Contingent Consideration. There were three milestones comprising the Milestone Contingent Consideration, in connection with the IGI Merger which iMDx valued and recorded as part of the contingent consideration as of the IGI Merger Date (see table below), which consisted of (i) a payment for clinical trial completion and related data publication (“Milestone 1”), (ii) a payment for an affirmative final LCD from CMS for a specified lung cancer test (“Milestone 2”), and (iii) a payment for achieving specified CMS reimbursement milestones (“Milestone 3”). If achieved, any respective Milestone will be paid at the contractual value shown below, with the payment made either in cash or in shares of iMDx's common stock as determined by iMDx. There can be no assurance that any of the Milestones will be achieved.

The following table shows the IGI Merger Date contractual payment amounts, as applicable, and the corresponding fair value of each respective contingent consideration liability:

|  | Contractual Value |  |  | Fair Value on the Merger Date |
|  | (In thousands) |
Milestone 1 (a) (c) |  | $ | 1,500 |  |  | $ | 1,340 |
Milestone 2 (a) |  |  | 3,000 |  |  |  | 1,830 |
Milestone 3 (a) |  |  | 1,500 |  |  |  | 770 |
Royalty 1 (b) (c) |  | See(b) |  |  |  | 5,980 |
Royalty 2 (b) (c) |  | See(b) |  |  |  | 1,210 |
Total |  | $ | 6,000 |  |  | $ | 11,130 |

(a)
Indicates the maximum amount payable if the Milestone is achieved.
(b)
As defined, Royalty Payments are based on a percentage of future revenues of DetermaIO and Laboratory Services over their respective useful life, accordingly there is no fixed contractual value for the Royalty Contingent Consideration.
(c)
Contingent consideration is currently not expected to be paid out.

The fair value of the contingent consideration after the IGI Merger Date is reassessed by iMDx as changes in circumstances and conditions occur, with the subsequent change in fair value recorded in iMDx’s consolidated statements of operations. Since December 2023, Milestone 1 and Royalty 2 (Laboratory Services) are not expected to be paid and are excluded from the current fair value. Since December 2025, Royalty 1 (DetermaIO) is not expected to be paid and is excluded from the current fair value. During 2026, based on iMDx’s reassessment of significant assumptions, there was a decrease of approximately $38,000 to the fair value of the contingent consideration primarily attributable to revised estimates of the possible future payouts and, accordingly, this amount was recorded as a change in fair value of contingent consideration in the consolidated statement of operations for the three months ended March 31, 2026.

iMDx uses a discounted cash flow valuation technique to determine the fair value of its Level 3 contingent consideration liabilities. The significant unobservable inputs used in IGI’s contingent consideration valuation on March 31, 2026, included: (i) a discount period, based on the expected Milestone payment dates, ranging from 1.7 years to 1.9 years, (ii) a discount rate of 13.7%, and (iii) a management probability estimate of 25% to 50%. The significant unobservable inputs used in IGI’s contingent consideration valuation on March 31, 2025, included: (i) a discount period, based on the expected Milestone payment dates, ranging from 1.7 years to 7.5 years, (ii) a discount rate of 13.2% to 13.4%, and (iii) a management probability estimate of 25% to 50%. Changes to significant unobservable inputs to different amounts could result in a significantly higher or lower fair value measurement at the reporting date.

Acquisition of Chronix

On April 15, 2021 (the “Chronix Merger Date”), iMDx completed its acquisition of Chronix pursuant to the Chronix Merger Agreement. As additional consideration for holders of certain classes and series of Chronix capital stock, the Chronix Merger Agreement required iMDx to pay certain contingent consideration. On February 8, 2023, the Company and the equity holder representative named in the Chronix Merger Agreement entered into Amendment No. 1 to the Chronix Merger Agreement, pursuant to which the parties agreed that (i) Chronix’s equity holders will be paid earnout consideration of 10% of net collections for sales of specified tests and products, until the expiration of intellectual property related to such tests and products, (ii) Chronix’s equity holders will be paid 5% of the gross proceeds received from any sale of all or substantially all of the rights, titles, and interests in and to Chronix’s patents for use in transplantation medicine to such third-party, and (iii) all of the previous payment obligations were eliminated.

The fair value of the Chronix contingent consideration after the Chronix Merger Date is reassessed by iMDx as changes in circumstances and conditions occur, with the subsequent change in fair value recorded in iMDx’s consolidated statements of operations. During 2026, based on iMDx’s reassessment of significant assumptions, there was a decrease of approximately $5.9 million to the fair value of the contingent consideration primarily attributable to revised estimates of the possible future payouts and, accordingly, this amount was recorded as a change in fair value of contingent consideration in the consolidated statement of operations for the three months ended March 31, 2026.

iMDx uses a discounted cash flow valuation technique to determine the fair value of its Level 3 contingent consideration liabilities. The significant unobservable inputs used in Chronix’s contingent consideration valuation on March 31, 2026, included: (i) a discount period, based on the related patent expiration dates, ranging from 8.6 years to 9.5 years, (ii) a discount rate of 13.7% to 14.2%, and (iii) a payout percentage of 10% based on the earnout provision. The significant unobservable inputs used in Chronix’s contingent consideration valuation on March 31, 2025, included: (i) a discount period, based on the related patent expiration dates, ranging from 9.6 years to 10.5 years, (ii) a discount rate of 13.2% to 13.5%, and (iii) a payout percentage of 10% based on the earnout provision. Changes to significant unobservable inputs to different amounts could result in a significantly higher or lower fair value measurement at the reporting date.

As of March 31, 2026 and December 31, 2025, R OU operating and financing lease assets accumulated amortization was $3.2 million and $2.8 million, respectively (see Note 6, “Operating and Financing Leases” for additional information). ROU financing lease assets, machinery, equipment and leasehold improvements total depreciation and amortization expense amounted to $631,000 and $484,000 for the three months ended March 31, 2026 and 2025, respectively.

5. Intangible Assets, Net

As part of the IGI and Chronix acquisitions completed on January 31, 2020 and April 15, 2021, respectively, the Company acquired IPR&D and customer relationships (see Note 3). In 2023 and 2024, the Company recorded partial impairments related to its DetermaIO and DetermaCNI IPR&D intangible assets.

As of December 31, 2025, due to growing competitive pressure in the oncology market, although not abandoned, management did not foresee substantial near term investment in, or revenue generating opportunities from, DetermaIO and DetermaCNI. Due to this current market condition, the Company’s long range plan forecasts were updated, resulting in a significant reduction to anticipated future benefits derived from the Company’s IPR&D assets. The IPR&D balances were reassessed based on the updated long range plan using the multi-period excess earnings method approach and the results of the valuations noted that the carrying values of the DetermaIO and DetermaCNI IPR&D intangible assets were gre ater than the fair market values, resulting in the full impairment of both assets. Accordingly, the Company recorded impairments of $2.9 million and $11.7 million related to DetermaIO and DetermaCNI, respectively, as of December 31, 2025.

The significant unobservable inputs used related to DetermaIO and DetermaCNI as of December 31, 2025, included: (i) a discount period of 15.0 years, based on the long range plan forecast, and (ii) a discount rate of 29.0%, as well as certain assumptions about future cash flows in the related long range plan forecast. This valuation approach yielded a fair value of zero for both DetermaIO and DetermaCNI as of December 31, 2025. See Note 2, “Intangible Assets” for additional IPR&D information.

Intangible assets subject to amortization included a customer relationship, at the acquired value of $440,000, which was fully amortized as of March 31, 2025. Intangible asset amortization expense amounted to $7,000 during 2025. Amortization of intangible assets was included in cost of revenues in the consolidated statement of operations because the intangible assets pertained directly to the revenues generated from the acquired intangibles.

6. Commitments and Contingencies

Office and Facilities Leases

Irvine Office Lease

On December 23, 2019, iMDx and Cushing Ventures, LLC (“Landlord”) entered into an Office Lease Agreement (the “Irvine Lease”) of a building containing approximately 26,800 square feet of rentable space located at 15 Cushing in Irvine, California (the “Premises”) that served as iMDx’s principal executive and administrative offices until June 2025 (see “Nashville Office and Facilities Leases” below). The Irvine Lease has a term of 89 calendar months (the “Term”), which commenced on June 1, 2020 (the “Commencement Date”) and will end on October 31, 2027. iMDx agreed to pay base monthly rent in the amount of $61,640 during the first 12 months of the Term. Base monthly rent increases annually, over the base monthly rent then in effect, by 3.5%. In June 2025, in connection with the Subtenant's (as defined below under the caption "Irvine Office Sublease") full usage of, and iMDx's exit of, the Premises, iMDx performed a recoverability test of the remaining lease related assets. Such lease asset group carrying amount was compared to the total undiscounted future expected cash flows from the sublease income, which resulted in no impairment.

Effective as of January 2, 2025, iMDx, Landlord and Subtenant (defined below) entered into an amendment to the Irvine Lease, dated December 26, 2024 (the “Amendment”). Pursuant to the terms of the Amendment, among other things: (a) iMDx and Subtenant agreed that all rights to extend the Term of the Irvine Lease for a period of five years were terminated, and (b) Landlord and iMDx agreed that, provided iMDx is not in default under any of the terms and conditions of the Irvine Lease that is continuing beyond any and all applicable notice and cure periods, then, commencing on July 1, 2025 and continuing on the first day of each calendar month thereafter, the provided letter of credit (as further discussed below) in the amount of $1.7 million (the “Letter of Credit Amount”) shall be reduced by an amount equal to $60,714.29 on each such date, until the Letter of Credit Amount is fully reduced, after which the letter of credit shall be deemed to have been terminated and iMDx shall have no further obligation to maintain or deliver the letter of credit under the Irvine Lease. The new Letter of Credit Amount will correspond to the Company’s restricted cash on the accompanying consolidated balance sheet and the reductions in the Letter of Credit Amount would correspondingly reduce the associated amount of such restricted cash.

In addition to base monthly rent, iMDx agreed to pay in monthly installments (a) all costs and expenses, other than certain excluded expenses, incurred by the lessor in each calendar year in connection with operating, maintaining, repairing (including replacements if repairs are not feasible or would not be effective) and managing the Premises and the building in which the Premises are located (“Expenses”), and (b) all real estate taxes and assessments on the Premises and the building in which the Premises are located, all personal property taxes for property that is owned by lessor and used in connection with the operation, maintenance and repair of the Premises, and costs and fees incurred in connection with seeking reductions in such tax liabilities (“Taxes”). Subject to certain exceptions, Expenses shall not be increased by more than 4% annually on a cumulative, compounded basis.

iMDx was entitled to an abatement of its obligations to pay Expenses and Taxes while constructing improvements to the Premises constituting “Tenant’s Work” under the Irvine Lease prior to the Commencement Date, except that iMDx was obligated to pay 43.7% of Expenses and Taxes during the period prior to the Commencement Date for its use of the second floor of the Premises, which was already built out as office space. The lessor provided iMDx with a “Tenant Improvement Allowance” in the amount of $1.3 million to pay for the plan, design, permitting, and construction of the improvements constituting Tenant’s Work. The lessor retained 1.5% of the Tenant Improvement Allowance as an administrative fee as provided in the Irvine Lease. As of June 2021, the lessor had provided $1.3 million of the total Tenant Improvement Allowance, which is being amortized over the Term.

iMDx provided the lessor with a security deposit in the amount of $150,000 and a letter of credit in the initial amount of $1.7 million. The lessor may apply the security deposit, in whole or in part, for the payment of rent and any other amount that iMDx is or becomes obligated to pay under the Irvine Lease but fails to pay when due and beyond any cure period. The lessor may draw on the letter of credit from time to time to pay any amount that is unpaid and due, or if the original issuing bank notifies the lessor that the letter of credit will not be renewed or extended for the period required under the Irvine Lease and iMDx fails to timely provide a replacement letter of credit, or an “event of default” under the Irvine Lease occurs and continues beyond the applicable cure period, or if certain instances of insolvency or bankruptcy with respect to iMDx occur. iMDx is required to restore any portion of the security deposit that is applied by the lessor to payments due under the Irvine Lease, and iMDx is required to restore the amount available under the letter of credit to the required amount if any portion of the letter of credit is drawn by the lessor. The Letter of Credit Amount shall be reduced as described in the Amendment above.

To obtain the letter of credit, iMDx has provided the issuing bank with a restricted cash deposit that the bank will hold to cover its obligation to pay any draws on the letter of credit by the lessor. The restricted cash may not be used for any other purpose. Corresponding to the Letter of Credit Amount, iMDx has reflected $1.2 million as the total remaining current and noncurrent restricted cash balances in the accompanying consolidated balance sheet as of March 31, 2026. The total restricted cash balance in the accompanying consolidated balance sheet as of December 31, 2025 was $1.3 million.

Irvine Office Sublease

On August 8, 2023, iMDx and Induce Biologics USA, Inc. (“Subtenant”) entered into a Sublease Agreement (the “Sublease Agreement”), which subsequently became effective as of September 14, 2023, upon the execution and delivery by the Company, Subtenant, and Landlord, of that certain Landlord’s Consent to Sublease dated September 12, 2023 (the “Consent Agreement”), under which Landlord consented to the Sublease Agreement, on the terms and subject to the conditions set forth therein. The Sublease Agreement is subject and subordinate to the Irvine Lease.

Under the Sublease Agreement, the Company agreed to initially sublet to Subtenant a portion of the Premises consisting of approximately 13,400 square feet of rentable space for a term (the “Initial Period”) commencing on the date that is 120 days after the effective date of the Consent Agreement (the “Sublease Commencement Date”) and ending on the date that is 18 months following the Sublease Commencement Date (June 20, 2025, the date on which the Initial Period ends, and the “Expansion Date”). On the Expansion Date, the portion of the Premises that is subleased to Subtenant under the Sublease Agreemen t automatically in creased to include the remaining portion of the Premises, which consists of approximately 13,400 square feet of additional rentable space for a term (the “Expansion Period”) beginning on the Expansion Date through the expiration of the Irvine Lease on October 31, 2027, unless earlier terminated.

The Sublease Agreement provides that, from and after the Sublease Commencement Date, Subtenant will pay to the Company monthly base rent in the following amounts: (i) $36,850 for rental periods beginning on the Sublease Commencement Date and ending on or before December 31, 2024; (ii) $37,955 for rental periods beginning on or after January 1, 2025 and ending on or before June 20, 2025; (iii) $75,844 for rental periods beginning on or after July 1, 2025 and ending on or before December 31, 2025; (iv) $78,188 for rental periods beginning on or after January 1, 2026 and ending on or before December 31, 2026; and (v) $80,534 for rental periods beginning on or after January 1, 2027 and ending on or before October 31, 2027.

Following the Sublease Commencement Date, Subtenant is responsible for the payment of Additional Rent, including Expenses and Taxes (as each such term is defined in the Irvine Lease), provided that, with respect to the Initial Period, Subtenant was responsible for only 50% of the Expenses and Taxes due. In addition, Subtenant paid the Company a security deposit in the amount of $101,987 in connection with the transactions contemplated by the Sublease Agreement.

The Sublease Agreement contains customary provisions with respect to, among other things, Subtenant’s obligation to comply with the Irvine Lease and applicable laws, the payment of utilities and similar services utilized by Subtenant with respect its use of the Premises, the indemnification of the Company by Subtenant, and the right of the Company to terminate the Sublease Agreement in its entirety and retake the Premises if Subtenant fails to remedy certain defaults of its obligations under the Sublease Agreement within specified time periods.

The lease line amount includes three options: (i) international equipment up to $500,000; (ii) sale and leaseback up to $1.0 million, whereby a liquidation value, based on a third-party appraiser of lessor’s choice, of the equipment will be utilized for the capitalized cost; both (i) and (ii) have an initial term of 24 months and a monthly rental factor of .0471; and (iii) new equipment up to $1.0 million with an initial term of 36 months and a monthly rental factor of .033. Actual monthly rentals will be determined by multiplying the original equipment capitalized cost by the applicable monthly rental factor, plus any monthly maintenance charges. At the end of an initial term, iMDx may return the equipment, exercise a purchase option, or extend for an additional 12 months at a monthly rental factor of .0175, plus any monthly maintenance charges. Currently, iMDx has not executed any lease schedules under the lease line agreement.

Litigation – General

iMDx may be subject to various claims and contingencies in the ordinary course of its business, including those related to litigation, business transactions, employee-related matters, and other matters. When iMDx is aware of a claim or potential claim, it assesses the likelihood of any loss or exposure. If it is probable that a loss will result and the amount of the loss can be reasonably estimated, iMDx will record a liability for the loss. If the loss is not probable or the amount of the loss cannot be reasonably estimated, iMDx discloses the claim if the likelihood of a potential loss is reasonably possible and the amount involved could be material.

Tax Filings

iMDx tax filings are subject to audit by taxing authorities in jurisdictions where it conducts business. These audits may result in assessments of additional taxes that are subsequently resolved with the authorities or potentially through the courts. Management believes iMDx has adequately provided for any ultimate amounts that are likely to result from these audits; however, final assessments, if any, could be significantly different than the amounts recorded in the consolidated financial statements. See Note 2, “Income Taxes” for additional information.

Employment Contracts

iMDx has entered into employment and severance benefit contracts with certain executive officers. Under the provisions of the contracts, iMDx may be required to incur severance obligations for matters relating to changes in control, as defined in the respective contracts, and certain terminations of executives. As of March 31, 2026 and December 31, 2025, iMDx accrued approximately $2.3 million, in severance obligations for certain executive officers, in accordance with the severance benefit provisions of their respective employment and severance benefit agreements, primarily related to iMDx’s acquisition of Chronix in 2021. For the periods presented, management has included $2.3 million of the accrued severance obligations related to the Chronix acquisition as contingent consideration in the consolidated balance sheets under contingent consideration liabilities, current and noncurrent. See Note 3, “Business Combinations and Contingent Consideration – Acquisition of Chronix” for additional information.

Indemnification

In the normal course of business, iMDx may provide indemnification of varying scope under iMDx’s agreements with other companies or consultants, typically iMDx’s clinical research organizations, investigators, clinical sites, suppliers and others. Pursuant to these agreements, iMDx will generally agree to indemnify, hold harmless, and reimburse the indemnified parties for losses and expenses suffered or incurred by the indemnified parties arising from claims of third parties in connection with the use or testing of iMDx’s diagnostic tests. Indemnification provisions could also cover third party infringement claims with respect to patent rights, copyrights, or other intellectual property pertaining to iMDx’s diagnostic tests. iMDx’s office and laboratory facility leases also will generally contain indemnification obligations, including obligations for indemnification of the lessor for environmental law matters and injuries to persons or property of others, arising from iMDx’s use or occupancy of the leased property. The term of these indemnification agreements will generally continue in effect after the termination or expiration of the particular research, development, services, lease, or license agreement to which they relate. iMDx periodically enters into underwriting and securities sales agreements with broker-dealers in connection with the offer and sale of iMDx securities. The terms of those underwriting and securities sales agreements include indemnification provisions pursuant to which iMDx agrees to indemnify the broker-dealers from certain liabilities, including liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), in connection with the offer and sale of iMDx securities. The potential future payments iMDx could be required to make under these indemnification agreements will generally not be subject to any specified maximum amounts. Historically, iMDx has not been subject to any claims or demands for indemnification. iMDx also maintains various liability insurance policies that limit iMDx’s financial exposure. As a result, iMDx management believes that the fair value of these indemnification agreements is minimal. Accordingly, iMDx has not recorded any liabilities for these agreements as of March 31, 2026 and December 31, 2025.

The Razor Stock Purchase Agreement (see Note 2, “Investments in Privately Held Companies”) also contains provisions under which iMDx has agreed to indemnify Razor and Encore Clinical, Inc., a former stockholder of Razor, from losses and expenses resulting from breaches or inaccuracy of iMDx’s representations and warranties and breaches or nonfulfillment of iMDx’s covenants, agreements, and obligations under the Razor Stock Purchase Agreement.

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.

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.

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.

8. Stock-Based Compensation

Equity Incentive Plan

In August 2018, iMDx shareholders approved an Equity Incentive Plan to replace the 2010 Stock Option Plan (the “2010 Plan”) and in October 2024, iMDx shareholders approved an amendment and restatement of such Equity Incentive Plan (as amended and restated, the “2018 Incentive Plan”). The 2018 Incentive Plan will expire on July 2, 2028. In initially adopting the 2018 Incentive Plan, iMDx terminated the 2010 Plan and ceased to grant any additional stock options or sell any stock under restricted stock purchase agreements under the 2010 Plan; however, stock options issued under the 2010 Plan continue in effect in accordance with their terms and the terms of the 2010 Plan until the exercise or expiration of the individual options. Total remaining stock options outstanding under the 2010 Plan as of March 31, 2026 and December 31, 2025, were 3,652 and 5,652, respectively.

As of March 31, 2026, 4,060,000 aggregate shares of common stock have been reserved for issuance under the equity incentive plans for the grant of stock options or the sale of restricted stock or for the settlement of RSUs. iMDx may also grant stock appreciation rights under the 2018 Incentive Plan. Upon the exercise of stock options, the issuance of RSAs, or the delivery of shares pursuant to vested RSUs or performance-based restricted stock units (“PSUs”), it is iMDx’s policy to issue new shares of common stock. The Board may amend or modify the 2018 Incentive Plan at any time, subject to any required stockholder approval. Shares available for grant under the 2018 Incentive Plan as of March 31, 2026 and December 31, 2025, were 530,200 and 528,200, respectively.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

In October 2024, the Company awarded 100,000 PSUs with market-based and service-based vesting conditions, and a grant date market price of $3.05 to a Company executive. Vesting is subject to continuous service as an employee of iMDx or a subsidiary thereof from hire date through the applicable vesting date, and shall performance vest as follows: (i) 50% will vest upon the Company’s achievement of an aggregate market value of voting and non-voting common equity held by non-affiliates of the Company of $75.0 million or more, such that the Company is no longer subject to the “Baby Shelf Rules” of Form S-3, and (ii) 50% will vest upon the Company’s achievement of a market capitalization of $200.0 million, which shall be determined based on the 30-day volume weighted average price of the common stock measured as of the end of each full calendar month following the date of grant. No units will vest prior to June 20, 2025, and any units that are not performance vested on December 31, 2026 shall automatically be forfeited. The fair value of such award was estimated using the Monte Carlo simulation model. Assumptions and estimates utilized in the model include the risk-free interest rate, dividend yield, expected stock volatility and the expected period to achievement of the market conditions. The grant date fair value and associated compensation cost of the market-based award reflect the probability of the market condition being achieved, and the Company will recognize this compensation cost regardless of the actual achievement of the market-based conditions. Assumptions utilized in connection with the Monte Carlo valuation technique included: estimated risk-free interest rate of 3.93 percent; term of 2.2 years; expected volatility of 90.0 percent; and expected dividend yield of 0 percent. The risk-free interest rate was determined based on the yields available on U.S. Treasury zero-coupon issues. The expected stock price volatility was determined using historical volatility. The expected dividend yield was based on expectations regarding dividend payments. Based on the two described performance vesting conditions, the grant date fair values were $2.03 and $1.43, respectively, amounting to a total fair value of $173,000. On October 31, 2025, 50,000 PSUs vested based on the achievement of an aggregate market value of common equity held by non-affiliates of $75.0 million or more, as described above. As of March 31, 2026, no additional awards have vested.

Stock-Based Compensation Expense

iMDx recorded stock-based compensation expense in the following categories on the accompanying consolidated statements of operations:

|  | Three Months Ended March 31, |

General and administrative |  |  | 398 |  |  |  | 240 |
Total |  | $ | 615 |  |  | $ | 473 |

Total unrecognized stock-based compensation expense as of March 31, 2026 was $5.2 million, which will be amortized over a weighted average remaining recognition period of 2.32 years.

Other Information

The determination of stock-based compensation is inherently uncertain and subjective and involves the application of valuation models and assumptions requiring the use of judgment. If iMDx had made different assumptions, its stock-based compensation expense and results for the periods presented may have been significantly different. See Note 2, “Stock-Based Compensation” for additional information.

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).

11. Segment Reporting

The Company operates and reports its results in one reportable segment, on a consolidated basis. The Company reports segment information based on the management approach and organizes its business based on products and services. The management approach designates the internal reporting information regularly reviewed by the chief operating decision maker (the “CODM”) to make decisions about resources to be allocated to the segment and assess its performance as the basis for determining a company’s reportable segments. The Company’s CODM is the senior executive management team that includes the Chief Executive Officer and Chief Financial Officer. iMDx is an early-stage diagnostics technology company with core operations that include the research, development and commercialization of diagnostic tests. Currently, the Company’s revenues include Laboratory Services from its life sciences customers, including testing for biomarker discovery, assay design and development, clinical trial support, and a broad spectrum of biomarker tests, and to a lesser extent from Kitted Products (see Note 2, “Revenue Recognition” for additional information). Additionally, the Company is primarily focused on developing and commercializing new diagnostic tests for medical use related to organ transplant and in the field of oncology, accordingly, extensive resources, time and expense will be required to complete the development and commercialization of those tests.

Adjusted earnings or loss before interest, income taxes, depreciation and amortization is the singular measure of segment profit or loss that the CODM uses in assessing segment performance and deciding how to allocate resources. This measure of segment profit or loss is used to monitor budget versus actual results and for long range planning. Segment loss in the table below includes revenues, cost of revenues, research and development, and other significant operating expenses directly attributable to our reportable segment. Such operating expenses exclude depreciation and amortization expenses, stock-based compensation, the change in fair value of contingent consideration, and impairments. As an early-stage company with limited revenue, management believes this measure of profit or loss is helpful in assessing our ongoing performance, providing insight into the Company’s core operating costs and performance by excluding certain noncash and other non-operating items that may obscure the underlying trends in the business. The reconciling items and significant segment expense categories and amounts, as included in the table below, are based on the Company’s internal general ledger reporting system that is used in preparing our consolidated financial statements and are included in determining the measure of segment profit or loss that is used by the CODM.

The measure of segment assets is reported in the consolidated balance sheets as total assets. Total segment expenditures for additions to long-lived assets is reported in the consolidated statements of cash flows as a component of cash used in investing activities.

The Company's single reportable segment profit or loss information is as follows:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations is intended to provide information necessary to understand our consolidated financial statements for the three months ended March 31, 2026 and 2025 included elsewhere in this Report, and highlight certain other information which, in the opinion of management, will enhance a reader’s understanding of our financial condition, changes in financial condition and results of operations. These historical consolidated financial statements may not be indicative of our future performance. This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains a number of forward-looking statements, all of which are based on our current expectations and could be affected by the uncertainties and risks described throughout this filing, particularly under “Risk Factors” in this Report and those “Risk Factors” in Part I, Item 1A. of our most recent Annual Report on Form 10-K for the year ended December 31, 2025 as filed with the SEC. For additional information, refer to the section above entitled “Cautionary Note Regarding Forward-Looking Statements.” The following discussion should be read in conjunction with our consolidated financial statements and the related notes thereto provided under Part I, Item 1 of this Report.

Overview

We are 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.

We are developing molecular diagnostic test kits designed to empower our customers to run their own tests in-house to participate in the patient-care value chain, which is counter-positioned with the send-out-testing central laboratory model. Our decentralized approach also puts testing in the hands of researchers to enable more studies, which we believe can improve standards of care while also creating demand for more testing. We believe that combining innovative science with a simple, but disruptive, business model can create substantial value. Our initial targeted customer institutions are hospitals, transplant centers and labs. The decisions to deploy our tests come from doctors, including surgeons, nephrologists and oncologists, as well as researchers, pathologists, lab directors, medical directors, department heads, lab managers and chief medical officers.

We are a science-driven organization that champions scientific integrity and inquiry. We employ scientists who generate intellectual property in our strategic target markets. We have built and acquired an intellectual property portfolio that we believe will enable us to gain share in well-established clinical and research markets.

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 LDTs that can be run at our Franklin, Tennessee laboratory, kitted RUO tests, and IVD kitted clinical tests that can be run by local labs.

Our primary near-term strategic market is organ transplant. We seek to deliver the industry-leading molecular diagnostic test kit for clinical use that decentralizes access to organ health testing for transplant patients. We expect that enabling in-house testing will deliver new value to the market for kitted transplant rejection testing. We also believe that decentralizing access to transplanted organ rejection testing will bring care closer to the patient and help hospitals to operate more sustainably, as well as create a rapidly growing, high-margin, recurring business model.

Our flagship transplant testing technology quantifies a molecular biomarker known as dd-cfDNA. Our scientists in Germany and the U.S. have played a critical role over the past decade in developing the science that helped establish dd-cfDNA as a trusted biomarker of transplanted organ rejection. Under the GraftAssure™ brand, our transplant diagnostics include the following:

•
GraftAssureCore – Our LDT, currently reimbursed by CMS and performed at our CLIA certified laboratory in Franklin, Tennessee.
•
GraftAssureIQ – An RUO kit intended and labeled for non-clinical applications.
•
GraftAssureDx – The IVD kit currently in development for use in clinical decision-making.

Our GraftAssure family of assays are performed on a digital PCR instrument that is manufactured by Bio-Rad. Consequently, we have entered into a global strategic partnership agreement with Bio-Rad to collaborate in the development and the commercialization of kitted transplant products for clinical use (see Note 10, “Collaborative Arrangements,” to our consolidated financial statements included elsewhere in this Report for additional information). In May 2025, we sold our first GraftAssureIQ kits to a research laboratory customer (see Note 2, “Revenue Recognition – Kitted Products,” to our consolidated financial statements included elsewhere in this Report for additional information).

Table of Contents

On February 20, 2026, we entered into a Specimen Collection Agreement with a national reference lab provider. Pursuant to the agreement, the lab provider will provide specimen collection-related services, which may include, among other things, the collection, handling, processing, and delivery of specimens upon which we will perform testing with our GraftAssureCore test.

Under strict regulatory rules, our kitted tests may not be used in a clinical treatment setting until they have attained marketing authorization from the Food and Drug Administration (“FDA”) for U.S. sales, and In Vitro Diagnostic Medical Devices Regulation approval, for European Union sales. As such, we are working with these regulatory bodies to attain such clearance and approval, as applicable, supporting future distribution and higher sales of our products for clinical use. In 2025, we started a clinical trial in conjunction with our IVD submission for GraftAssureDx. On March 25, 2026, we submitted a data package to the FDA seeking marketing authorization for GraftAssureDx, which is the kitted version of our transplanted organ rejection monitoring assay. We believe that our assays will perform across multiple tissue, or organ, types, and we are pursuing regulatory authorization in kidneys first.

We also have a services lab, certified under the CLIA and accredited by the College of American Pathologists, in Franklin, Tennessee, and research and development labs in Nashville, Tennessee and Göttingen, Germany. Our innovation centers in Nashville and Germany employ research scientists whom we believe are leaders in their fields.

Our secondary strategic market is in the field of oncology. The inherent uncertainties of developing and commercializing new diagnostic tests for medical use make it impossible to predict the amount of time and expense that will be required to complete the development and commercialization of our oncology tests. We continue to dedicate a minimum amount of resources to our oncology assays, DetermaIO and DetermaCNI, although currently we do not intend to commercialize either in the next 12 months.

We also perform other assay development and clinical testing services for life sciences and biotechnology companies through our Laboratory Services operations.

We believe that the experience of our team with diverse technologies through our Laboratory Services activities, strong scientific integrity regarding evidence generation and innovation mentality, alongside our flexibility in operations and regulatory strategy, will drive our success, differentiate us from our competition, and are foundational to our future. We are focusing on executing the technology priorities discussed herein, which have evolved to reflect our operations and strategic vision.

Results of Operations – Three Months Ended March 31, 2026 Compared with the Three Months Ended March 31, 2025

Total net revenue decreased to $32,000 for the three months ended March 31, 2026, compared to $2.1 million in the comparable prior period primarily from Laboratory Services as further discussed below. Future Laboratory Services revenue is expected to be impacted as a result of our shift in strategic focus on commercializing our transplant kitted tests, and deploying our sales personnel toward signing new laboratory customers.

Net loss was $4.3 million for the three months ended March 31, 2026, compared to $6.7 million for the comparable prior period. Net loss decreased by $2.4 million primarily due to the change in fair value of contingent consideration, which was partially offset by a decrease in Laboratory Services revenue and increases in operating expenses. Further details related to the change in net loss are as follows:

•
Laboratory Services revenue decreased by $2.1 million. We earned Laboratory Services revenue from one existing customer in the amount of approximately $32,000 during 2026. See below for additional revenue information.
•
Cost of revenues decreased by $796,000, primarily related to labor and allocated overhead associated with performing our Laboratory Services. See below for additional cost of revenues information.
•
Research and development expenses increased by $2.0 million, as we continue development of GraftAssureCore, GraftAssureIQ and GraftAssureDx. The main drivers of the increase were clinical trials, professional fees, personnel-related expenses, facilities and insurance, and laboratory costs. See below for additional details.
•
Sales and marketing expenses increased by $1.2 million, primarily attributable to continued ramp up in sales, marketing and advertising activities related to the transplant business. The main drivers of the increase were personnel-related expenses and professional fees. See below for additional details.
•
General and administrative expenses decreased by $124,000, primarily due to decreases in professional fees, and facilities and insurance, partially offset by stock-based compensation, and personnel-related expenses and board fees. See below for additional details.
•
Change in fair value of contingent consideration was a gain of $5.9 million in 2026 compared to a loss of $879,000 in 2025. This change was due to changes in the fair value model inputs and revised estimates on if and when future payouts will occur. See below for additional information.
•
Total other income, net decreased by $5,000, primarily due to losses in money market funds, partially offset by additional interest income related to higher cash balances from our February 2025 Offering and February 2026 Offering. See below for additional details.

Revenues

The following table shows our revenues by type:

|  | Three Months Ended March 31, |
|  | 2026 |  |  | 2025 |  |  | $ Change |  |  | % Change |
|  | (In thousands, except percentage change values) |
Laboratory Services |  | $ | 32 |  |  | $ | 2,138 |  |  | $ | (2,106 | ) |  |  | (99 | )%
Kitted Products |  |  | — |  |  |  | — |  |  |  | — |  |  |  | — |
Total |  | $ | 32 |  |  | $ | 2,138 |  |  | $ | (2,106 | ) |  |  | (99 | )%

Laboratory Services are generally performed on a time and materials basis. Upon our completion of the service to the customer in accordance with the contract, we have the right to bill the customer for the agreed upon price (either on a per test or per deliverable basis) and recognize the Laboratory Services revenue at that time, on an accrual basis. Laboratory Services revenues are generated under discrete agreements for particular customer projects that generally expire with the completion or termination of the customer’s project. Accordingly, different customers may account for greater or lesser portions of Laboratory Services during different accounting periods, and Laboratory Services revenues may exhibit a larger variance from accounting period to accounting period than other revenues. Future Laboratory Services revenue is expected to be impacted as a result of our shift in strategic focus on commercializing our transplant kitted tests, and deploying our sales personnel toward signing new laboratory customers. See Note 2, “Revenue Recognition – Laboratory Services” and “Disaggregation of Revenues and Concentrations of Credit Risk,” to our consolidated financial statements included elsewhere in this Report for additional information.

Kitted Products include our GraftAssureIQ RUO kitted tests sold to research laboratory customers, which are clearly labeled and intended for research purposes. GraftAssureIQ is a transplant monitoring assay to measure the dd-cfDNA molecular biomarker. See Note 2, “Revenue Recognition – Kitted Products,” to our consolidated financial statements included elsewhere in this Report for additional information.

Cost of Revenues

Cost of revenues generally consists of cost of materials, direct labor including benefits, bonus and stock-based compensation, equipment and infrastructure expenses, clinical sample related costs associated with performing Laboratory Services, providing deliverables according to our licensing agreements, license fees due to third-parties, and Kitted Products inventory costs and royalties based on net product sales. Infrastructure expenses include depreciation of laboratory equipment, allocated rent costs, leasehold improvements, and allocated information technology costs for operations at our CLIA-certified laboratory in Tennessee. Costs associated with generating service revenue are recorded as the tests or services are performed regardless of whether revenue was recognized. Royalties or revenue share payments for licensed technology calculated as a percentage of revenues generated using the associated technology, or from product sales, are recorded as expenses at the time the related revenues are recognized. Cost of revenues for Laboratory Services varies depending on the nature, timing, and scope of customer projects.

(1)
Certain prior period amounts have been reclassified to conform to the current period presentation. These changes had no impact on the previously reported total research and development expenses.

We expect to continue to incur a significant amount of research and development expenses for the foreseeable future. We will continue development of GraftAssureCore, GraftAssureIQ and GraftAssureDx. Our future research and development efforts and expenses will also depend on the amount of capital that we are able to raise to finance those activities and whether we acquire rights to any new diagnostic tests. A portion of our costs for leasing and operating our CLIA-certified laboratory in Tennessee, and our facilities in Germany, will also be included in research and development expenses to the extent allocated to the development of our diagnostic tests.

In 2025, we started a clinical trial in conjunction with our IVD submission for GraftAssureDx. On March 25, 2026, we submitted a data package to the FDA seeking marketing authorization for GraftAssureDx, which is the kitted version of our transplanted organ rejection monitoring assay.

Sales and Marketing Expenses

A summary of the main drivers of the change in sales and marketing expenses is as follows:

|  | Three Months Ended March 31, |
|  | 2026 |  |  | 2025 (1) |  |  | $ Change |  |  | % Change |
|  | (In thousands, except percentage change values) |

Table of Contents

We expect to continue to incur sales and marketing expenses for the foreseeable future, especially as we continue to commercialize GraftAssureCore, GraftAssureIQ and GraftAssureDx. Our commercialization efforts and expenses will also depend on the amount of capital that we are able to access to finance commercialization of our tests. Our future expenditures on sales and marketing will also depend on the amount of revenue that those efforts are likely to generate. Because physicians are more likely to prescribe a test for their patients if the cost is covered by Medicare or health insurance, demand for our diagnostic and other tests and our expenditures on sales and marketing are likely to increase if our diagnostic or other tests qualify for reimbursement by Medicare or private health insurance companies.

General and Administrative Expenses

A summary of the main drivers of the change in general and administrative expenses is as follows:

|  | Three Months Ended March 31, |
|  | 2026 |  |  | 2025 (1) |  |  | $ Change |  |  | % Change |
|  | (In thousands, except percentage change values) |
Personnel-related expenses and board fees |  | $ | 1,378 |  |  | $ | 1,241 |  |  | $ | 137 |  |  |  | 11 | %

Change in Fair Value of Contingent Consideration

We will pay contingent consideration if various payment milestones are triggered under the merger agreements through which we acquired IGI and Chronix. In 2025, we earned our first Kitted Products revenue and, accordingly, we began to pay related royalties to Chronix. Changes in the fair value of the contingent consideration will be based on our reassessment of the key assumptions underlying the determination of this liability as changes in circumstances and conditions occur from the IGI and Chronix acquisition dates to the reporting periods being presented, with the subsequent changes in fair value recorded as part of our consolidated results from operations for such periods. See Note 3 to our consolidated financial statements included elsewhere in this Report for additional information.

Other Income and Expenses

Other income and expenses are primarily comprised of interest income, interest expense, and foreign currency gains and losses (see Note 2, “Foreign Currency Gains and Losses,” to our consolidated financial statements included elsewhere in this Report). Interest income is earned from money market funds we hold for capital preservation. Interest expense is incurred from our financing lease obligations (see Note 6 to our consolidated financial statements included elsewhere in this Report) and insurance financing activity.

Income Taxes

We did not record any provision or benefit for income taxes for the three months ended March 31, 2026 and 2025, as we had a full valuation allowance for the periods presented. A valuation allowance is provided when it is more-likely-than-not that some portion of the deferred tax assets will not be realized. We established a full valuation allowance for all periods presented due to the uncertainty of realizing future tax benefits from our net operating loss carry-forwards and other deferred tax assets. See Note 2, “Income Taxes,” to our consolidated financial statements included elsewhere in this Report for additional information.

Inflation

Although historically not significant to our results of operations, financial condition and cash flows, we may experience inflationary pressures, primarily in personnel costs, with certain laboratory supplies, from inventory costs related to certain raw materials, with essential vendors including audit fees and regulatory consultants, and from tariff policies and potential countermeasures. Prices for raw materials may fluctuate based on a number of factors beyond our control, including changes in supply and demand, general economic conditions, labor costs, fuel related delivery costs, competition, import duties, excises and other indirect taxes, currency exchange rates, and government regulation. The extent of any future impacts from inflation on our business and our results of operations will depend upon how long elevated inflation levels persist and the extent to which the rate of inflation were to increase, if at all, neither of which we are able to predict. If elevated levels of inflation were to persist or if the rate of inflation were to accelerate, the purchasing power of our cash and cash equivalents may be diminished, our expenses could increase faster than anticipated and we may utilize our capital resources sooner than expected. Due to the highly competitive nature of the healthcare industry and the cost containment efforts of our customers and third-party payors, we may be unable to pass along cost increases for key components or raw materials through higher prices to our customers. Further, given the complexities of the reimbursement landscape in which we operate, our payers may be unwilling or unable to increase reimbursement rates to compensate for inflationary impacts. As such, the effects of inflation may adversely impact our results of operations, financial condition and cash flows. See Note 1, “Business Risks,” to our consolidated financial statements included elsewhere in this Report for additional information about the risks that may impact our business.

Liquidity and Capital Resources

Our foreseeable material cash requirements as of March 31, 2026, are recognized as liabilities in the consolidated balance sheet or generally are otherwise described in Note 6, “Commitments and Contingencies,” to our consolidated financial statements included elsewhere in this Report. Our cash requirements are generally derived from our operating and investing activities including expenditures for working capital, human capital, equipment purchases, lease payments, business development, investments in intellectual property, and business combinations. Our office lease obligations (net of sublease payments) and financing lease obligations, and contingent consideration obligations are further described in Note 6 and Note 3, respectively, to our consolidated financial statements included elsewhere in this Report. As of March 31, 2026 and December 31, 2025, other than certain equity-classified warrants (see Note 7, “Common Stock Purchase Warrants,” to our consolidated financial statements included elsewhere in this Report), we had no off-balance sheet arrangements, and historically we have not entered into any such arrangements other than the noted warrants. As of March 31, 2026 and December 31, 2025, we had unrecognized tax benefits totaling $1.6 million (see Note 2, “Income Taxes,” to our consolidated financial statements included elsewhere in this Report).

Since formation, we have financed our operations primarily through the sale of our common stock, preferred stock and warrants to acquire common stock (see Note 7 to our consolidated financial statements included elsewhere in this Report). We have incurred operating losses and negative operating cash flows since inception and had an accumulated deficit of $405.1 million as of March 31, 2026. At March 31, 2026, we had $28.2 million of cash and cash equivalents. On February 12, 2026, we raised additional capital as discussed below. Management anticipates that we may continue to incur operating losses and negative operating cash flows for the near future. Although it is difficult to predict our liquidity requirements, based on the going concern evaluation discussed in Note 1, “Liquidity,” to our consolidated financial statements included elsewhere in this Report, 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.

On February 10, 2025, we consummated the February 2025 Offering. 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, our global strategic partner. We are using the net proceeds received for general corporate purposes and working capital. See Note 7, “Common Stock – February 2025 Offering,” to our consolidated financial statements included elsewhere in this Report for additional information.

On February 12, 2026, we consummated 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 of $1.4 million, the resulting net proceeds were approximately $24.6 million. These net proceeds were inclusive of an investment from Bio-Rad, our global strategic partner. We are using the net proceeds primarily for general corporate purposes and working capital, including research and development in the transplantation category. The net proceeds from the offering will allow us to invest in research and development with the goal of expanding our GraftAssure product offering beyond kidney transplant rejection testing into other organs, and most immediately, into heart transplant rejection testing. See Note 7, “Common Stock – February 2026 Offering,” to our consolidated financial statements included elsewhere in this Report for additional information.

Our remaining restricted cash balance in the total amount of $1.2 million as of March 31, 2026 relates to a bank letter of credit required under our Irvine office lease. From July 1, 2025 and continuing on the first day of each calendar month thereafter, the letter of credit will be reduced by an amount equal to $60,714.29 on each such date, until the letter of credit is fully reduced, after which the letter of credit arrangement will terminate and we will have no further obligation to maintain or deliver the letter of credit. See Note 6, “Office and Facilities Leases – Irvine Office Lease,” to our consolidated financial statements included elsewhere in this Report for additional information.

We expect that our general operating expenses will be commensurate with the market opportunity as we continue to manage our available cash. Although we intend to market our diagnostic tests in the United States through our own sales force, we are also making marketing arrangements with distributors in other countries. We are exploring a range of other commercialization options in order to enter overseas markets and to reduce our capital needs and expenditures, and the risks associated with the timelines and uncertainty for attaining the Medicare reimbursement approvals that will be essential for the successful commercialization of additional diagnostic tests. Those alternative arrangements could include marketing arrangements with other diagnostic companies through which we might receive a licensing fee and royalty on sales, or through which we might form a joint venture to market one or more tests and share in net revenues, in the United States or abroad.

In April 2024, we entered into a global strategic partnership 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. In November 2024, we entered into a memorandum of understanding with Bio-Rad with respect to such agreement to establish additional activities to be performed by each party pursuant to such agreement. Due to the significance of our arrangement with Bio-Rad, we are dependent on them with respect to many of our ongoing operations and future target performance, which also results in a concentration in the volume of business transacted with Bio-Rad. In addition, Bio-Rad is a significant investor in our common stock. For more information regarding our transactions and business with Bio-Rad, see Note 9, “Related Party Transactions” and Note 10, “Collaborative Arrangements,” to our consolidated financial statements included elsewhere in this Report.

On February 20, 2026, we entered into a Specimen Collection Agreement with a national reference lab provider. Pursuant to the agreement, the lab provider will provide specimen collection-related services, which may include, among other things, the collection, handling, processing, and delivery of specimens upon which we will perform testing with our GraftAssureCore test, a blood test designed to measure dd-cfDNA using a novel PCR-based measurement platform, for potential patient registrants. The agreement provides for certain fees to be paid to the lab provider for services rendered. The lab provider will not bill any other party for the services it provides, and patients will be billed by us.

In addition to research, development, sales and marketing expenses, we will incur other expenses from leasing and improving our offices and laboratory facilities in the Nashville, Tennessee area and Göttingen, Germany. We have recently expanded our Nashville and Germany facilities by extending and adding new office and laboratory leases. In addition, we have added various new laboratory instruments to be used in our transplant operations, under new financing leases or from purchases. As of March 31, 2026, we have acquired a total of 34 new lab instruments for use in our transplant operations. As of December 31, 2025, we had a total of 32 lab instruments. See Note 6, “Commitments and Contingencies,” to our consolidated financial statements included elsewhere in this Report for additional operating and financing lease information.

We may need to meet significant cash payment or stock obligations to former IGI and Chronix shareholders in connection with our acquisition of those companies, as disclosed in Note 3 to the consolidated financial statements included elsewhere in this Report. As of March 31, 2026 and December 31, 2025, total contingent consideration liabilities were $38.0 million and $43.9 million, respectively. To meet the future cash payment obligations, we may have to utilize cash on hand that would otherwise be available to us for other business and operational purposes, which could cause us to delay or reduce activities in the development and commercialization of our tests. In 2025, we earned our first Kitted Products revenue, accordingly, we began to pay related royalties to Chronix.

Table of Contents

We may need to continue to access additional forms of capital, beyond what is provided by cash flow from operations, to finance our operations, including the development and commercialization of our diagnostic tests, and making payments that may become due under our obligations to former IGI and Chronix shareholders, until such time as we are able to generate sufficient revenues to cover our operating expenses. Delays in our collaborative arrangement for the development and the commercialization of RUO and IVD kitted transplant products, or delays in obtaining regulatory approval to distribute our products for clinical use, or delays in the development of, or in obtaining reimbursement coverage from Medicare for future laboratory tests that we may develop or acquire, could prevent us from raising sufficient additional capital to finance the completion of development and commercial launch of those tests. However, additional financing may not be available on acceptable terms, if at all, including due to difficult conditions in the capital markets, particularly with respect to securities of biotechnology and life sciences companies on the U.S. stock exchanges. Investors may be reluctant to provide us with capital until our tests are approved for reimbursement by Medicare or reimbursement by private healthcare insurers or healthcare providers, or until we begin generating significant amounts of revenue from selling and performing those tests.

The unavailability or inadequacy of financing or revenues to meet future capital needs could force us to modify, curtail, delay, or suspend some or all aspects of our planned operations. Sales of additional equity securities could result in the dilution of the interests of our shareholders.

See Note 1 and Note 7 to our consolidated financial statements included elsewhere in this Report for additional information about our liquidity discussion and equity offerings, respectively.

Cash Flow from Operating Activities

During the three months ended March 31, 2026, our total research and development expenses were $5.0 million, our sales and marketing expenses were $2.4 million, and our general and administrative expenses were $3.0 million. We also incurred $17,000 in total cost of revenues. Net loss for the period was $4.3 million, and our net cash used in operating activities amounted to $7.6 million. Our cash used in operating activities during 2026 did not include the following noncash items: $631,000 in depreciation and amortization expenses, $615,000 in stock-based compensation, $32,000 in other equity compensation expenses, $5.9 million gain from the change in fair value of contingent consideration, and unrealized foreign currency gains of $5,000. Net changes in operating assets and liabilities for the period were $1.3 million as a source of additional cash.

During the three months ended March 31, 2025, our total research and development expenses were $2.9 million, our sales and marketing expenses were $1.2 million, and our general and administrative expenses were $3.1 million. We also incurred $813,000 in total cost of revenues, including $7,000 for amortization of intangible assets. Net loss for the period was $6.7 million, and our net cash used in operating activities amounted to $5.8 million. Our cash used in operating activities during 2025 did not include the following noncash items: $491,000 in depreciation and amortization expenses, $473,000 in stock-based compensation, $14,000 in other equity compensation expenses, $879,000 loss from change in fair value of contingent consideration, and unrealized foreign currency losses of $39,000. Net changes in operating assets and liabilities for the period were $1.1 million as an additional use of cash.

Cash Flow from Investing Activities

During the three months ended March 31, 2026, net cash used in investing activities was $613,000 from cash paid for purchases of machinery and equipment, and construction in progress.

During the three months ended March 31, 2025, net cash used in investing activities was $307,000 from cash paid for purchases of machinery and equipment, and construction in progress.

Cash Flow from Financing Activities

During the three months ended March 31, 2026, net cash provided by financing activities was $24.7 million from $24.8 million of net cash proceeds from the February 2026 Offering, partially offset by repayments of financing lease obligations of $143,000.

During the three months ended March 31, 2025, net cash provided by financing activities was $28.6 million from $28.7 million of net cash proceeds from the February 2025 Offering, partially offset by repayments of financing lease obligations of $98,000.

Critical Accounting Estimates

Our consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles. In preparing these financial statements, we make assumptions, judgments and estimates that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial condition or results of operations. We base our assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. On a regular basis, we evaluate our assumptions, judgments and estimates and make changes accordingly.

We believe that of the significant accounting policies discussed in Note 1 and Note 2 to our consolidated financial statements included elsewhere in this Report, the following accounting policies involve a significant level of estimation uncertainty and require our most difficult, subjective or complex assumptions, judgments and estimates:

•
Going Concern Assessment;
•
Contingent Consideration Liabilities;
•
Impairment of Long-Lived Assets;
•
Revenue Recognition and Allowance for Credit Losses;
•
Stock-Based Compensation; and
•
Income Taxes.

Going Concern Assessment

We assess going concern uncertainty in our consolidated financial statements to determine if we have sufficient cash and cash equivalents on hand and working capital, including available loans or lines of credit, if any, to operate for a period of at least one year from the date our consolidated financial statements are issued (the “look-forward period”). As part of this assessment, based on conditions that are known and reasonably knowable to us, we consider various scenarios, forecasts, projections and estimates, including stress tests, and we make certain key assumptions, including the timing and nature of projected cash expenditures or programs, and our ability to delay or curtail those expenditures or programs, if necessary, among other factors. Based on this assessment, as necessary or applicable, we make certain assumptions around implementing curtailments or delays in the nature and timing of programs and expenditures to the extent we deem probable those implementations can be achieved and we have the proper authority to execute them within the look-forward period. For additional information, including our current assessment results, see Note 1 to our consolidated financial statements included elsewhere in this Report.

Contingent Consideration Liabilities

Contingent consideration is estimated and recorded at fair value as of the acquisition date as part of the total consideration transferred. Contingent consideration is an obligation of the acquirer to transfer additional assets or equity interests to the selling shareholders in the future if certain future events occur or conditions are met, such as the attainment of product development milestones. Contingent consideration also includes additional future payments to selling shareholders based on achievement of components of earnings, such as “earn-out” provisions or percentage of future revenues, including royalties paid to the selling shareholders based on a percentage of certain revenues generated.

The fair value of milestone-based contingent consideration was determined using a scenario analysis valuation method which incorporates our assumptions with respect to the likelihood of achievement of the milestones, as defined in the merger agreements, credit risk, timing of the contingent consideration payments and a risk-adjusted discount rate to estimate the present value of the expected payments, all of which require significant management judgment and assumptions. Since the contingent consideration payments are based on nonfinancial, binary events, management believes the use of the scenario analysis method is appropriate.

The fair value of royalty or revenue share-based contingent consideration was determined using a single scenario analysis method to value those payments. The single scenario method incorporates our assumptions with respect to specified future revenues generated over their respective useful lives, credit risk, and a risk-adjusted discount rate to estimate the present value of the expected royalty payments, all of which require significant management judgment and assumptions. Since the royalty-based contingent consideration payments are based on future revenues and linear payouts, management believes the use of the single scenario method is appropriate.

49

Table of Contents

The fair value of contingent consideration after the acquisition date is reassessed by us as changes in circumstances and conditions occur, with the subsequent change in fair value recorded in our consolidated statements of operations. Changes in key assumptions can materially affect the estimated fair value of contingent consideration liabilities and, accordingly, the resulting gain or loss that we record in our consolidated financial statements. During the three months ended March 31, 2026 and 2025, we recorded a gain of $5.9 million and a loss of $879,000, respectively, related to the fair value of contingent consideration. As of March 31, 2026 and December 31, 2025, total contingent consideration liabilities were $38.0 million and $43.9 million, respectively. As of March 31, 2026, a hypothetical 2% increase and 2% decrease in the discount rate would have resulted in total contingent consideration liabilities of $34.5 million and $42.0 million, respectively. For additional information, see Note 3 to our consolidated financial statements included elsewhere in this Report.

Impairment of Long-Lived Assets

We assess the impairment of long-lived assets, which consists primarily of right-of-use assets, machinery and equipment, and finite-lived intangible assets, whenever events or changes in circumstances indicate that such assets might be impaired and the carrying value may not be recoverable. When such events or changes in circumstances are present, we estimate the future cash flows expected to result from the use of the asset (or asset group) and its eventual disposition. If the sum of the expected undiscounted future cash flows is less than the carrying amount, we recognize an impairment based on the fair value of such assets.

Revenue Recognition and Allowance for Credit Losses

Laboratory Services

Laboratory Services are generally performed under individual SOW arrangements or license agreements (together with SOW the “Laboratory Services Agreements”) with specific deliverables defined by the customer. Laboratory Services are performed on a (i) time and materials basis or (ii) per test completed basis. Upon completion of the service to the customer in accordance with a Laboratory Services Agreement, we have the right to bill the customer for the agreed upon price (either on a per test or per deliverable basis) and recognize Laboratory Service revenue at that time. Depending on the Laboratory Services Agreement, we may identify the services offered as a single performance obligation, or identify the processing of test samples as a separate performance obligation (considered a series) within license agreements. Completion of the service and satisfaction of the performance obligation is typically evidenced by acknowledgment of completed services, and access to the report or test made available to the customer or any other form or applicable manner of delivery defined in the Laboratory Services Agreements. However, for certain SOWs under which work is performed pursuant to the customer’s highly customized specifications, we have the enforceable right to bill the customer for work completed, rather than upon completion of the SOW. For those SOWs, we recognize revenue over a period during which the work is performed using a formula that accounts for expended efforts, generally measured in labor hours, as a percentage of total estimated efforts for the completion of the SOW. As performance obligations are satisfied under the Laboratory Services Agreements, any amounts earned as revenue and billed to the customer are included in accounts receivable.

We establish an allowance for credit losses based on the evaluation of the collectability of its Laboratory Services accounts receivables after considering a variety of factors, including the length of time receivables are past due, significant events that may impair the customer’s ability to pay, such as a bankruptcy filing or deterioration in the customer’s operating results or financial condition, reasonable and supportable forecast that affect the collectability of the reported amount, and historical experience. We continuously monitor collections and payments from customers and maintain a provision for estimated credit losses and uncollectible accounts, if any, based upon its historical experience and any specific customer collection issues that have been identified. Amounts determined to be uncollectible are written off against the credit loss reserve accounts. As of March 31, 2026 and December 31, 2025, we had an allowance for credit losses of $2,000 and $11,000, respectively, related to Laboratory Services.

Stock-Based Compensation

We recognize compensation expense related to stock-based payment awards made to employees, board directors and other non-employees based on estimated fair values. We estimate the fair value of stock-based payment awards on the grant date and recognize the resulting fair value over the requisite service period on a straight-line basis. For stock-based awards that vest only upon the attainment of one or more performance goals, compensation cost is recognized if and when we determine that it is probable that the performance condition or conditions will be, or have been, achieved. For grants with market-based and time-based vesting conditions, the fair value is estimated using the Monte Carlo simulation model, which includes the estimated period to achievement of the performance and market conditions, which are subject to the achievement of the market-based goals established by us and continued employment. We utilize the Black-Scholes option pricing model for determining the fair value of standard time-based stock options. Our determination of fair value of stock-based payment awards on the date of grant using an option pricing model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. We estimate the expected volatility using our own stock price volatility for a period equal to the expected term of the options. The expected term of options granted is based on our own experience. The risk-free rate is based on the U.S. Treasury rates in effect during the corresponding period of grant. Key inputs and assumptions may change as we continue to develop our Company estimates, experience and key inputs including our expected term, and stock price volatility based on the trading history of our stock in the public market. Changes in these subjective assumptions can materially affect the estimated value of equity grants and the stock-based compensation that we record in our consolidated financial statements. During the three months ended March 31, 2026 and 2025, we recognized total stock-based compensation of $615,000 and $473,000, respectively. For additional information, see Note 8 to our consolidated financial statements included elsewhere in this Report.

Income Taxes

We account for income taxes in accordance with Accounting Standards Codification 740, Income Taxes, which prescribes the use of the asset and liability method, whereby deferred tax asset or liability account balances are calculated at the balance sheet date using current tax laws and rates in effect. The provision for income taxes for interim periods is determined using an estimated annual effective tax rate in accordance with ASC 740-270, Income Taxes, Interim Reporting. Valuation allowances are established when necessary to reduce deferred tax assets when it is more-likely-than-not that a portion or all of the deferred tax assets will not be realized. Our judgments regarding future taxable income may change over time due to changes in market conditions, changes in tax laws, tax planning strategies or other factors. If our assumptions and consequently our estimates change in the future, the valuation allowance may be increased or decreased, which may have a material impact on our statements of operations.

The guidance also prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not sustainable upon examination by taxing authorities. We will recognize accrued interest and penalties, if any, related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of the financial statement periods presented herein. We account for uncertain tax positions by assessing all material positions taken in any assessment or challenge by relevant taxing authorities. We are currently unaware of any tax issues under review. For additional information, see Note 2, “Income Taxes,” to our consolidated financial statements included elsewhere in this Report.
