| Accounting Policies [Abstract] | |
| Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. These estimates, judgments, and assumptions are based on historical data and experience available at the date of the accompanying consolidated financial statements, as well as various other factors management believes to be reasonable under the circumstances. The Company’s estimates and assumptions may evolve as conditions change. Actual results could differ significantly from these estimates. On an on-going basis, management evaluates its estimates, primarily those related to: (i) revenue recognition criteria, (ii) accounts receivable and allowances for credit losses, (iii) the useful lives of fixed assets and intangible assets, (iv) estimates of tax liabilities, (v) valuation of goodwill and indefinite-lived intangible assets at time of acquisition and on a recurring basis, and (vi) valuation of investments. |
| Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company. All intercompany transactions and balances have been eliminated in consolidation. |
| Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents include cash held in banks and money market accounts. Cash equivalents are stated at fair value. |
| Restricted Cash | Restricted Cash Restricted cash consists of legally restricted deposits held in conjunction with a lease contract the Company entered into with a third-party landlord. A bank guarantee equivalent to six months of gross rent plus tax with an expiry date three months post the lease expiry is required under the lease contract, and the lease contract will expire in March 2034. Restricted deposit is recorded in other long-term assets in the Company’s Consolidated Balance Sheets as the balance is not expected to be released to cash within the next 12 months. As of December 31, 2024, the Company had restricted cash of $ 0.1 million . The Company did no t have restricted cash as of December 31, 2023 . |
| Marketable Securities | Marketable Securities All marketable debt securities, which consist of U.S. government and agency debt securities, U.S. treasury bills, corporate debt securities, municipal bonds, and Yankee debt securities issued by foreign governments or entities and denominated in U.S. dollars have been classified as “available-for-sale,” and are carried at fair value. Net unrealized gains and losses, net of any related tax effects, are excluded from earnings and are included in other comprehensive income (loss) and reported as a separate component of stockholders’ equity until realized. Realized gains and losses on marketable debt securities are included in interest income, in the accompanying Consolidated Statements of Operations. The cost of any marketable debt securities sold is based on the specific-identification method. The amortized cost of marketable debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Interest on marketable debt securities is included in interest income. In accordance with the Company’s investment policy, management invests to diversify credit risk and only invests in securities with high credit quality, including U.S. government securities. The Company’s investments in marketable equity securities are measured at fair value with the related gains and losses, realized and unrealized, recognized in interest income, in the accompanying Consolidated Statements of Operations. The cost of any marketable equity securities sold is based on the specific-identification method. For available-for-sale debt securities, in an unrealized loss, the Company determines whether a credit loss exists. The credit loss is estimated by considering available information relevant to the collectability of the security and information about past events, current conditions, and reasonable and supportable forecasts. The Company compares the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows to be collected is less than the amortized basis of the security, a credit loss exists, and an allowance for credit losses is recorded for the credit loss, limited by the amount of unrealized loss. Changes in the allowance are recorded in the period of changes as credit loss expense. If the Company has an intent to sell, or if it is more likely than not that the Company will be required to sell a debt security in an unrealized loss position before recovery of its amortized cost basis, the Company will write down the security to its fair value and record the corresponding charge as a component of other income, net. |
| Trade Accounts Receivable and Allowance for Credit Losses | Trade Accounts Receivable and Allowance for Credit Losses Trade accounts receivable are stated at the amount the Company expects to collect. The Company maintains an allowance for credit losses for expected uncollectible trade accounts receivable, which is recorded as an offset to trade accounts receivable, and changes in allowance for credit losses are classified as a general and administrative expense in the accompanying Consolidated Statements of Operations. The Company assesses collectability by reviewing trade accounts receivable on a collective basis where similar risk characteristics exist and on an individual basis when it identifies specific customers that have deterioration in credit quality such that they may no longer share similar risk characteristics with the other receivables. In determining the amount of the allowance for credit losses, the Company uses a loss rate model or probability-of-default and loss given default model. Following the loss rate method, expected credit losses are determined based on an estimated historical loss rate. The probability of default method allows the ability to define a point of default and measure credit losses for receivables that have reached the point of default for purposes of calculating the allowance for credit losses. Loss given default represents the likelihood that a receivable that has reached the point of default will not be collected in full. The Company updates its loss rate and factors annually to incorporate the most recent historical data and adjusts the quantitative portion of the reserve through its qualitative reserve overlay. The Company looks at qualitative factors such as general economic conditions in determining expected credit losses. A roll-forward of the activity in the Company’s allowance for credit losses is as follows:
2024 2023 2022
(in thousands)
Allowance for credit losses at beginning of year $ 25,226 $ 41,205 $ 11,217
Current period (gain) provision ( 1,730 ) ( 880 ) 32,596

Allowance for credit losses at end of year $ 20,458 $ 25,226 $ 41,205 |
| Preferred Stock Investment | Preferred Stock Investment The redeemable preferred stock investment of $ 20.4 million as of December 31, 2023, represents the fair value of the 7.3 million shares of preferred stock of a privately-held, Cayman Islands company, Laboratory for Advanced Medicine, Inc., or LAMH, doing business as “Helio Health” that the Company purchased in July 2021. Helio Health is an AI-biotechnology company developing blood-based early cancer detection tests, and the Company expected to gain access to an emerging liquid biopsy testing technology, through this strategic partnership. As the preferred stock had the option to be redeemed, the investment was initially recorded as available-for-sale debt securities with changes in fair value recorded in other comprehensive income (loss). On June 19, 2024, the Board of Directors of LAMH approved to spin out certain U.S.-based laboratory and development operations into a separate, privately-held Delaware corporation, Helio Genomics, Inc., or Helio Genomics. The Company received 7.3 million shares of preferred stock of Helio Genomics in connection with this spin-out. Post spin-out, Helio Genomics amended and restated its certificate of incorporation on July 25, 2024, which resulted in a change in stockholder’s rights where the Company no longer holds the right to redeem its preferred stock of Helio Genomics. As a result, the Company reclassified $ 0.4 million unrealized gain out of accumulated other comprehensive income (loss) to net income (loss) in the consolidated financial statements. The Company elected to record its preferred stock investment in Helio Genomics under the measurement alternative in accordance with ASC 321, defined as cost less impairment, adjusted for subsequent observable price changes and are periodically assessed for impairment when events or circumstances indicate that a decline in value may have occurred. As of July 25, 2024, the preferred stock investment carrying value of $ 9.9 million was recorded as other long-term assets in the Consolidated Balance Sheets. No impairment loss was recorded as of December 31, 2024. Post spin-out, the Company retained the original right to redeem its LAMH preferred stock. As the preferred stock had the option to be redeemed, the investment was recorded as available-for-sale debt securities with changes in fair value recorded in other comprehensive income (loss). The Company considered a number of factors including, but not limited to: (i) the extent to which the fair value of the investment is less than its amortized cost; (ii) the financial condition and near-term prospects of the investee, and (iii) general market conditions. As a result, the Company recognized a $ 10.1 million credit loss during the year ended December 31, 2024, recorded as impairment of available-for-sale debt securities in the Consolidated Statements of Operations. The roll-forward for the allowance for credit losses related to the available-for-sale debt securities is as follows:

| Business Combinations | Business Combinations The Company uses the acquisition method of accounting and allocates the fair value of purchase consideration to the assets acquired and liabilities assumed from an acquiree based on their respective fair values as of the acquisition date. The excess of the fair value of purchase consideration over the fair value of these assets acquired and liabilities assumed is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets. Critical estimates in valuing intangible assets include, but are not limited to, expected future cash flows, which includes consideration of future growth and margins, future changes in technology, expected cost and time to develop in-process research and development, brand awareness and discount rates. Fair value estimates are based on the assumptions that management believes a market participant would use in pricing the asset or liability. |
| Fixed Assets | Fixed Assets Fixed assets are recorded at cost, net of accumulated depreciation and amortization. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are capitalized and amortized over the shorter of their expected lives or the applicable lease term, including renewal options, if available. Major replacements and improvements are capitalized, while general repairs and maintenance are expensed as incurred. See Note 5, Fixed Assets , for useful lives for each major class of fixed assets. |
| Finite-Lived Intangible assets | Finite-Lived Intangible assets Intangible assets, unless determined to be indefinite-lived, are amortized over their estimated useful lives. The Company amortizes intangible assets on a straight-line basis with definite lives generally over periods ranging from three to 14 years . See Note 17, Goodwill and Intangible Assets , for details of intangible assets. |
| Goodwill and Indefinite-lived Intangibles | Goodwill and Indefinite-lived Intangibles In-process research & development, or IPR&D, costs are considered to be indefinite-lived until the completion or abandonment of the associated research and development efforts. If and when development is complete, the associated assets would be deemed finite-lived and would then be amortized based on their respective estimated useful lives at that point in time. The Company assesses goodwill and indefinite-lived intangibles for impairment on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company may choose to bypass a qualitative assessment of impairment for any reporting unit and proceed directly to performing a quantitative assessment. An impairment loss would be recognized for the amount by which the reporting unit's carrying amount exceeds its fair value. The Company’s quantitative assessment includes estimating the fair value of each reporting unit and comparing it to its carrying value. The Company estimates the fair value of reporting units using both income-based and market-based valuation methods and typically engages a third-party appraisal firm to assist with the valuation. The estimated fair value for each reporting unit is determined based upon the range of estimated values developed from the income and market-based methods. If the estimated fair value of a reporting unit exceeds its carrying value, the goodwill is not impaired, and no further review is required. The income-based fair value methodology is based on a reporting unit’s forecasted future cash flows that are discounted to the present value using the reporting unit’s weighted-average cost of capital, or WACC. Under the income-based approach, it requires management’s assumptions and judgments regarding economic conditions in the markets in which the company operates and conditions in the capital markets, many of which are outside of management’s control. The market-based fair value methodology looks at the guideline public company valuation method to determine the prices of comparable public companies and looks at merger and acquisition methods, similar businesses that were sold recently, to estimate the value of the reporting units. Under the market-based approach, judgment is required in evaluating market multiples and recent transactions. The Company performed an annual goodwill and intangible asset impairment test on December 31, 2024, and elected to bypass the optional qualitative test and perform the quantitative assessments for its therapeutic development reporting units, which includes an indefinite-lived intangible asset. |
| Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company evaluates the carrying amount of its long-lived assets whenever events or changes in circumstances indicate that the assets may not be recoverable. An impairment loss would be recognized when estimated future cash flows expected to result from the use of an asset and its eventual disposition is less than the carrying amount of the asset. |
| Reagents and Supplies | Reagents and Supplies The Company maintains reagents and other consumables primarily used in testing which are valued at the lower of cost or net realizable value. Cost is determined using actual costs on a first-in, first-out basis. The reagents and other consumables were included in other current assets in the accompanying Consolidated Balance Sheets. |
| Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company’s financial instruments consist principally of cash and cash equivalents, marketable securities, trade accounts receivable, restricted cash, a redeemable preferred stock investment, preferred stock investments, accounts payable, and accrued liabilities. The carrying amounts of certain of these financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximate fair value due to their short maturities. Fair value of marketable securities, the redeemable preferred stock investment, and the preferred stock investments is disclosed in Note 4, Fair Value Measurement s, to the accompanying consolidated financial statements. |
| Concentrations of Credit Risk, Customers and Suppliers | Concentrations of Credit Risk, Customers and Suppliers Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents, trade accounts receivable, and marketable securities. As of December 31, 2024, substantially all of the Company’s cash and cash equivalents were deposited in accounts at financial institutions, and amounts may exceed federally insured limits. Management believes that the Company is not exposed to significant credit risk due to the financial strength of the depository institutions in which its cash and cash equivalents are held. In certain periods, a small number of customers has accounted for a significant portion of the Company’s revenue. For the laboratory services segment, aggregating customers under common control, one customer comprised of $ 62.6 million or 22 % of total revenue in the year ended December 31, 2024, and the same customer comprised of $ 35.7 million or 12 % of total revenue in the year ended December 31, 2023. A different customer comprised of $ 115.6 million or 19 % of total revenue in the year ended December 31, 2022. One customer comprised 15 % of total accounts receivable, net, as of December 31, 2024, and the same customer comprised 13 % of total accounts receivable, net, as of December 31, 2023. For the therapeutic development segment, the Company doesn't have customers or revenue as it does not have any commercialized or approved drug candidates. The Company’s therapeutic development business relies on ANP Technologies, Inc. for certain laboratory services, equipment, tools, and drug intermediates in connection with research and development efforts. The Company also relies on a limited number of suppliers for certain laboratory substances used in the chemical reactions incorporated into its processes, referred to as reagents, as well as for the sequencers and various other equipment and materials it uses in its laboratory operations. In particular, the Company relies on a sole supplier for the next generation sequencers and associated reagents it uses to perform its genetic tests and as the sole provider of maintenance and repair services for these sequencers. The Company’s laboratory operations would be interrupted if it encountered delays or difficulties securing these reagents, sequencers, other equipment or materials or maintenance and repair services, which could occur for a variety of reasons, including if the Company needs a replacement or temporary substitute for any of its limited or sole suppliers and is not able to locate and make arrangements with an acceptable replacement or temporary substitute. The Company’s development efforts could also be delayed or interrupted if it is unable to procure items needed for its therapeutic development activities. The Company believes there are currently only a few other manufacturers that are capable of supplying and servicing some of the equipment and other materials necessary for its laboratory operations, including sequencers and various associated reagents. |
| Leases | Leases The Company determines if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether the Company obtains substantially all of the economic benefits from and has the ability to direct the use of the asset. Operating and finance lease right-of-use assets, or ROU assets, short-term lease liabilities, and long-term lease liabilities are included in other long-term assets, accrued liabilities, and other long-term liabilities, respectively, in the accompanying Consolidated Balance Sheets. Lease ROU assets represent the Company’s right to use an underlying asset for the lease term. Lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term, including options to extend the lease when it is reasonably certain that the Company will exercise that option. The Company uses its incremental borrowing rate based on the information available at the commencement date, including inquiries with its bank, in determining the present value of lease payments when its leases do not provide an implicit or explicit rate. Lease ROU assets consist of initial measurement of lease liabilities, any lease payments made to lessor on or before the lease commencement date, minus any lease incentive received, and any initial direct costs incurred by the Company. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term. For finance lease, ROU assets are amortized on a straight-line basis from the commencement date to the earlier of the end of useful life of the ROU assets or the end of the lease term. Amortization of ROU assets and interest on the lease liability for finance leases are included as charges to the accompanying Consolidated Statements of Operations. Lease ROU assets and liabilities arising from business combinations are recognized and measured at the acquisition dates as if an acquired lease were a new lease at the date of acquisition using the Company’s incremental borrowing rate unless the discount rate is implicit in the lease. The Company elects to not to recognize assets or liabilities as of the acquisition dates for leases that, on the acquisition dates, have a remaining lease term of 12 months or less. The Company also retains the acquirees’ classification of the leases if there are no modifications as part of the business combinations. The Company leased out space in buildings it owns to third-party tenants under noncancelable operating leases. The Company recognized lease payments as income over the lease terms on a straight-line basis and recognized variable lease payments as income in the period in which the changes in facts and circumstances on which the variable lease payments were based occurred. The net rental income was included in the other income, net, in the accompanying Consolidated Statements of Operations. |
| Software for Internal Use | Software for Internal Use The Company capitalizes certain costs incurred to purchase computer software for internal use. These costs include purchased software packages for Company use. Capitalized computer software costs are amortized over the estimated useful life of the computer software, which is generally one to 10 years . Internally developed software costs are capitalized after management has committed to funding the project, it is probable that the project will be completed and the software will be used for its intended function. Costs that do not meet that criteria and costs incurred on projects in the preliminary and post-implementation phases are expensed as incurred. |
| Reportable Segment and Geographic Information | Reportable Segment and Geographic Information Reporting segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions regarding resource allocation and assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. The Company reports its business in two segments, a laboratory services business and a therapeutic development business. For further financial information about these segments, including information for each of the last three fiscal years regarding revenue, operating income (loss), and other important information, see Note 7, Reportable Segment and Geographic Information . |
| Revenue Recognition | Revenue Recognition The Company generates revenue from sales of its testing services. The Company currently receives payments from primarily three different customer types: insurance payors, institutional customers, including hospitals, medical institutions, other laboratories, governmental bodies, municipalities, and large corporations, and patients who pay directly. The Company recognizes revenue in an amount that reflects the consideration to which it expects to be entitled in exchange for the transfer of promised goods or services to its customers. To determine revenue recognition for contracts with customers, the Company performs the following steps described in ASC 606: (1) identifies the contract with the customer, or Step 1, (2) identifies the performance obligations in the contract, or Step 2, (3) determines the transaction price, or Step 3, (4) allocates the transaction price to the performance obligations in the contract, or Step 4, and (5) recognizes revenue when (or as) the entity satisfies a performance obligation, or Step 5. The Company’s test results are primarily delivered electronically. The Company bills certain customers for shipping and handling fees incurred by the Company, and shipping and handling fees billed to customers are included in revenue, and such shipping and handling fees incurred are included in cost of revenue in the accompanying Consolidated Statements of Operations. Performance Obligations Institutional and Patient Direct Pay The Company’s institutional contracts for its testing services typically have a single performance obligation to deliver testing services to the ordering facility or patient. In arrangements with institutions, including hospitals, medical institutions, other laboratories, governmental bodies, municipalities, and large corporations, and patients who pay directly, the transaction price is stated within the contract and is therefore fixed consideration. For most of the Company’s testing, the Company identified the institutions, including hospitals, medical institutions, other laboratories, governmental bodies, municipalities, and large corporations, and patients as the customer in Step 1 and have determined a contract exists with those customers in Step 1. As these contracts typically have a single performance obligation, no allocation of the transaction price is required in Step 4. Control over testing services is transferred to the Company’s ordering facility at a point in time. Specifically, the Company determined the customer obtains control of the promised service upon delivery of test results. The Company enters into contracts with research institutions to perform testing and research services. Revenue is recognized as each individual test is completed, as the Company has a right to payment upon completion of each test. While the contract represents a single performance obligation to provide testing and research services, the revenue is recognized as the individual tests are completed and the results are delivered to the customer. Each completed test is considered a measurable event that indicates the transfer of control to the customer, at which point revenue is recognized. The Company regularly reviews its contracts and recognizes revenue in accordance with the completion of each test, based on the right to payment and the transfer of control. Insurance The Company’s insurance contracts for testing services typically have a single performance obligation to deliver testing services to the ordering facility or patient. For most of the Company’s insurance revenue, the Company identified the patient as the customer in Step 1 and determined a contract exists with the patient in Step 1. In arrangements with insurance patients, the transaction price is typically stated within the contract, however, the Company may accept payments from insurance payors that are less than the contractually stated price, therefore estimation of the transaction price is considered variable consideration. In developing the estimate of variable consideration, the Company utilizes the expected value method under a portfolio approach. As these contracts typically have a single performance obligation, no allocation of the transaction price is required in Step 4. Control over testing services is transferred to the Company’s ordering parties at a point in time. Specifically, the Company determined the customer obtains control of the promised service upon delivery of the test results. Certain incremental costs pertaining to both insurance and institutional, such as commissions, are incurred in obtaining contracts. Contract costs are capitalized if the Company expects to recover them, and amortization of contract costs is classified in the general and administrative expense in the Consolidated Statements of Operations. Historically contract costs have not been significant to the financial statements. Significant Judgments and Contract Estimates Accounting for insurance contracts includes estimation of the transaction price, defined as the amount the Company expects to be entitled to receive in exchange for providing the services under the contract. Due to the Company’s out-of-network status with various insurance payors, estimation of the transaction price represents variable consideration. In the absence of Medicare coverage, contractually established reimbursement rates or other coverage, we have concluded that our contracts include variable consideration because the amounts paid by Medicare or commercial health insurance carriers may be paid at less than our standard rates or not paid at all, with such differences considered implicit price concessions. Variable consideration attributable to these price concessions measured at the expected value using the “most likely amount” method under ASC 606. The amounts are determined by the historical average collection rates by test type taking into consideration the range of possible outcomes, the predictive value of our past experiences, the time period of when uncertainties expect to be resolved and the amount of consideration that is susceptible to factors outside of our influence, such as the judgment and actions of insurance payors. Such variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainties with respect to the amount are resolved. Variable consideration may be constrained and excluded from the transaction price in situations where there is no contractually agreed upon reimbursement coverage or in the absence of a predictable pattern and history of collectability with a payor. The Company re-assesses its estimated transaction price at the end of each reporting period, including an assessment of whether the estimate variable consideration is constrained to the extent that is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. The Company records any necessary adjustments in the current period’s revenue. $ 1.8 million and $ 23.0 million variable consideration was recognized as additional revenue in the years ended December 31, 2024 and 2023 , respectively, that related to collections for COVID-19 tests completed in the prior period. Disaggregation of Revenue The Company classifies its customers into three payor types: (i) Institutional, including hospitals, medical institutions, other laboratories, governmental bodies, municipalities, and large corporations, (ii) Insurance, including claim reimbursement from HRSA for uninsured individuals, or (iii) Patients who pay directly, as the Company believes this best depicts how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors. The following table summarizes revenue from contracts with customers by payor type for the years ended December 31, 2024, 2023, and 2022.
Year Ended December 31,
2024 2023 2022
(in thousands)
Revenue by payor
Institutional $ 154,733 $ 134,191 $ 239,961
Insurance 123,924 151,946 377,873
Patient 4,813 3,076 1,134
Total revenue $ 283,470 $ 289,213 $ 618,968 The insurance revenue category above includes zero for the years ended December 31, 2024 and 2023, and $ 83.1 million for the year ended December 31, 2022 for services related to claims covered by the HRSA COVID-19 Uninsured Program. During the years ended December 31, 2024 and 2023, the Company experienced a change in estimate related to variable consideration. $ 1.8 million and $ 23.0 million variable consideration were recognized in the years ended December 31, 2024 and 2023, respectively, related to COVID-19 test services completed in the prior periods due to collection efforts, which was included as revenue from insurance in the table above. The Company estimates variable consideration using the expected value method. Any changes in variable consideration estimates that affect transactions are accounted for on a cumulative catch-up basis. Contract Balances Receivables from contracts with customers - Receivables from contracts with customers are included within trade accounts receivable on the Consolidated Balance Sheets. Receivables from Insurance and Institutional customers represented 44 % and 56 % , respectively, as of December 31, 2024 and 39 % and 61 % , respectively, as of December 31, 2023. Contracts assets and liabilities - Contract assets from contracts with customers associated with contract execution and certain costs to fulfill a contract are included in other current assets in the accompanying Consolidated Balance Sheets. Contract liabilities are recorded when the Company receives payment prior to completing its obligation to transfer goods or services to a customer. Contract liabilities are included in the Consolidated Balance Sheets. Revenues of $ 2.5 million , $ 2.2 million and $ 14.4 million for the years ended December 31, 2024, 2023, and 2022, respectively, related to contract liabilities at the beginning of the respective periods were recognized. Transaction Price Allocated to Future Performance Obligations ASC 606 issued by the Financial Accounting Standards Board, or FASB, requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of December 31, 2024. ASC 606 provides certain practical expedients that limit the requirement to disclose the aggregate amount of transaction price allocated to unsatisfied performance obligations. The Company applied the practical expedient to no t disclose the amount of transaction price allocated to unsatisfied performance obligations when the performance obligation is part of a contract that has an original expected duration of one year or less. The Company does not have material future obligations associated with its testing services that extend beyond one year. |
| Contract Liabilities | Contract Liabilities Contract liabilities are recorded when the Company receives payment or bills prior to completing its obligation to transfer goods or services to a customer, and the Company subsequently recognizes contract liabilities as revenue in the period in which the applicable revenue recognition criteria, as described above, are met. |
| Customer Deposit | Customer Deposit Customer deposit in the accompanying Consolidated Balance Sheets consists of payments received from customers in excess of their outstanding trade accounts receivable balances. These deposits will be offset against future testing receivables or refunded to the customers. |
| Overhead Expenses | Overhead Expenses The Company allocates overhead expenses, such as facility, rent, and utilities, to cost of revenue and operating expense categories based on square footage. As a result, an overhead expense allocation is reflected in cost of revenue and each operating expense category. |
| Cost of Revenue | Cost of Revenue Cost of revenue reflects the aggregate costs incurred in delivering test results and consists of: personnel costs, including salaries, employee benefit costs, bonuses, and equity-based compensation expenses; costs of laboratory supplies; depreciation of laboratory equipment; amortization of leasehold and building improvements and allocated overhead. Costs associated with performing tests are recorded as tests are processed. |
| Research and Development Expenses | Research and Development Expenses Research and development expenses represent costs incurred to develop the Company’s technology and future tests. These costs consist of: personnel costs, including salaries, employee benefit costs, bonuses, and equity-based compensation expenses; laboratory supplies; consulting costs and allocated overhead. The Company expenses all research and development costs in the periods in which they are incurred. |
| Selling and Marketing Expenses | Selling and Marketing Expenses Selling and marketing expenses consist of: personnel costs, including salaries, employee benefit costs, bonuses, and equity-based compensation expenses; customer service expenses; direct marketing expenses; educational and promotional expenses; market research and analysis and allocated overhead. The Company expenses all selling and marketing costs as incurred. |
| General and Administrative Expenses | General and Administrative Expenses General and administrative expenses include executive, finance and accounting, legal, and human resources functions. These expenses consist of: personnel costs, including salaries, employee benefit costs, bonuses, and equity-based compensation expenses; audit and legal expenses; consulting costs and allocated overhead. The Company expenses all general and administrative expenses as incurred. |
| Restructuring Costs | Restructuring Costs Restructuring costs represent one-time employee termination benefits provided to employees associated with an acquired entity that were involuntarily terminated. A plan of termination was approved and authorized by management in the second quarter of 2022. The plan identified specific employees to be terminated and established terms of benefits those employees would receive upon termination. No additional costs are expected to be incurred under the plan of termination post 2022, and the full amount was paid off by August 2023 . |
| Income Taxes | Income Taxes Income taxes are accounted for under the asset and liability method. The Company provides for federal, state and foreign income taxes currently payable, as well as for taxes deferred due to timing differences between reporting income and expenses for financial statement purposes versus tax purposes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in income tax rates is recognized as income or expense in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount with a greater than 50% likelihood of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. For income tax positions where it is not more likely than not that a tax benefit will be sustained, the Company does not recognize a tax benefit in its consolidated financial statements. The Company records interest and penalties related to uncertain tax positions, if applicable, as a component of income tax expense. The Company releases income tax effects from other comprehensive income (loss) under the portfolio method. In 2024, the Company reclassified certain investments out of the available-for-sale debt security category. This reclassification resulted in the removal of unrealized gains or losses previously recorded in other comprehensive income (loss). The tax effects of these adjustments have been recognized, as a benefit of $ 2.1 million, in net loss to avoid stranded tax effects in other comprehensive income (loss). |
| Equity-Based Compensation | Equity-Based Compensation The Company grants various types of equity-based awards to its employees, consultants, and non-employee directors. Equity-based compensation costs are reflected in the accompanying Consolidated Statements of Operations based upon each award recipient’s role with the Company. The Company primarily grants to its employees restricted stock unit awards, or RSU awards, that generally vest over a specified period of time upon the satisfaction of service-based conditions or performance conditions. Compensation expense for employee RSU awards with a service-based vesting condition is recognized ratably over the vesting period of the award. Compensation expense for employee RSU awards with a performance condition is based on the probable outcome of that performance condition. The Company measures compensation expense for equity-based awards granted to employees based on the fair value of the award on the grant date of the award. |
| Foreign Currency Translation and Foreign Currency Transactions | Foreign Currency Translation and Foreign Currency Transactions The Company translates the assets and liabilities of its non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period. Expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from these translations are recognized in foreign currency translation gain (loss) included in the accompanying Consolidated Statements of Comprehensive Income (Loss). The Company and its subsidiaries that use the U.S. dollar as their functional currency remeasure monetary assets and liabilities at exchange rates in effect at the end of each period, and inventories, property and nonmonetary assets and liabilities at historical rates. Gains and losses from these measurements are included in other income, net, in the accompanying Consolidated Statements of Operations. Losses from foreign currency exchange were not significant in 2024, 2023, and 2022 . |
| Comprehensive (Loss) Income | Comprehensive (Loss) Income Comprehensive (loss) income is comprised of net (loss) income and other comprehensive (loss) income. Other comprehensive (loss) income consists of net unrealized gain or loss on available-for-sale debt securities, net of tax, and foreign currency translation adjustments from its subsidiaries not using the U.S. dollar as their functional currency. Reclassification from other comprehensive (loss) income to net loss, which includes reclassification of stranded tax effects, was $ 3.6 million in 2024. Reclassifications from other comprehensive income (loss) to net earnings were not significant in 2023 or 2022. Th e tax effects related to net unrealized gain or loss on available-for-sale debt securities were zero in 2024 and 2023, due to the valuation allowance in the current period that precludes the Company from recognizing the deferred tax benefit, and $ 7.2 million in 2022 . |
| Basic and Diluted Net Income or Loss per Share | Basic and Diluted Net Income or Loss per Share Basic net income or loss per common share is computed by dividing the net income or loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income or loss per common share is computed by dividing the net income or loss attributable to common stockholders by the weighted-average number of common shares and dilutive common share equivalents outstanding during the period. |
| Prior Period Reclassifications | Prior Period Reclassifications Certain amounts reported in the prior periods have been reclassified to conform with the current period presentation. In the Consolidated Statements of Cash Flow, the Company has separated prepaid income taxes from its previous inclusion in other current and long-term assets and separated customer deposits, and contract liabilities from its previous inclusion in accrued liabilities and other liabilities. In the Consolidated Statements of Operations, the Company has also separated interest income, and interest expenses from its previous inclusion in other income, net. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements The Company evaluates all Accounting Standards Updates, or ASUs, issued by the Financial Accounting Standards Board, or FASB, for consideration of their applicability. ASUs not included in the Company’s disclosures were assessed and determined to be either not applicable or are not expected to have a material impact on the Company’s consolidated financial statements or disclosures. Adopted In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segments .

Issued In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures . This update requires more detailed information on certain income tax disclosures including the income tax rate reconciliation and income taxes paid. Amendments in this update are effective for annual periods beginning December 15, 2024 for public entities, and early adoption is permitted. This update will result in enhanced income tax disclosures, and the Company does not expect any impact to income tax expense. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses . This update requires disclosure in the notes to financial statements, of specified information about certain costs and expenses.

The Company is currently evaluating the impacts of this amendment on the consolidated financial statements and related disclosure. The Company does not expect that any other recently issued accounting guidance will have a significant effect on its consolidated financial statements. |
