Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X for interim financial information and reflect all adjustments necessary to state fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. All such adjustments are of a normal recurring nature. Results for interim periods are not indicative of the results for the entire fiscal year. The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. Certain information and footnote disclosures, including significant accounting policies, normally included in fiscal year financial statements prepared in accordance with accounting principles generally accepted in the U.S. (GAAP) have been condensed or omitted. The condensed balance sheet as of March 31, 2025 was derived from the audited financial statements.

Certain information and footnote disclosures for prior period amounts have been included and reclassified to conform to the current period presentation pursuant to ASU No. 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures (ASC Topic 280). See Note 15 — Segment Reporting for additional information.

Concentrations of Credit Risk and Other Uncertainties

Substantially all of the Company’s cash and cash equivalents are deposited with one major financial institution in the United States. The Company continually monitors its positions with, and the credit quality of, the financial institution with which it holds cash. Periodically throughout the year, the Company has maintained balances in various operating and money market accounts in excess of federally insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents.

Several of the components for certain of the Company's sample collection kits, test reagents, and test systems are obtained from single-source suppliers. If these single-source suppliers fail to satisfy the Company's requirements on a timely basis, the Company could suffer delays in being able to deliver its diagnostic solutions, a possible loss of revenue, or incur higher costs, any of which could adversely affect our results of operations.

In addition, there is currently significant uncertainty about the future relationship between the U.S. and various other countries with respect to trade policies, treaties, tariffs and taxes. Current or future tariffs imposed by the U.S. may negatively impact our business. The extent to which these threats will be enacted and the duration for which enacted tariffs will be in place remain uncertain and could negatively affect our results of operations. The Company is currently evaluating our vendor relationships and assessing the overall impact of these trade policies, however, we do not expect a material impact to the financial statements.

For a discussion of credit risk concentration of accounts receivable as of March 31, 2025 and December 31, 2024, see Note 9 – Revenue and Accounts Receivable Credit Concentration.

Inventory

Inventory consists primarily of material supplies, which are consumed in the performance of assembly and testing services and charged to ‘Direct costs and expenses’. Inventory is stated at cost and reported within ‘Other current assets’ in the condensed balance sheets and was $1.1 million and $1.0 million as of March 31, 2025 and December 31, 2024, respectively. The Company recorded an insignificant reserve for excess inventory as of March 31, 2025 and December 31, 2024, respectively. During both the three months ended March 31, 2025 and 2024, the Company recorded an insignificant amount to the condensed statements of operations for excess and obsolete inventory.

Fair Value of Financial Instruments

U.S. GAAP for fair value establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). We utilize a combination of market and income approaches to value our financial instruments. Our financial assets and liabilities are measured using inputs from the three levels of the

fair value hierarchy. Fair value measurements are categorized within the fair value hierarchy based upon the lowest level of the most significant inputs used to determine fair value.

The three levels of the hierarchy and the related inputs are as follows:


Level		Inputs
1		Unadjusted quoted prices in active markets for identical assets and liabilities.
2		Unadjusted quoted prices in active markets for similar assets and liabilities;
		Unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active; or
		Inputs other than quoted prices that are observable for the asset or liability.
3		Unobservable inputs for the asset or liability.

The carrying amounts of certain financial instruments including cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, other long-term assets, accounts payable and accrued liabilities approximate fair value due to their relatively short maturities.

See Note 4 — Fair Value for further discussion related to estimated fair value measurements.

Recently Issued Accounting Standards

Standards Being Evaluated

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid by jurisdiction. This guidance became effective for the Company for the annual period beginning on January 1, 2025, and will become effective for interim periods beginning on January 1, 2026. The Company is currently evaluating this guidance and assessing the overall impact on its financial statements.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. This ASU improves the transparency of a public business entity's expense disclosures by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, SG&A, and research and development). This guidance will become effective for the Company for the annual period beginning on January 1, 2027, and interim periods beginning on January 1, 2028, with early adoption permitted. The Company is currently evaluating this guidance and assessing the overall impact on its financial statements.
