Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation and Consolidation The Company’s condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP, and in conjunction with the rules and regulations of the Securities and Exchange Commission, or the SEC. The accompanying condensed consolidated financial statements include the accounts of Guardant Health, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company adjusted the accompanying condensed consolidated balance sheet as of December 31, 2023 to separately present accounts payable and accrued expenses, inclusive of accrued compensation. In addition, certain other reclassifications of prior period amounts were made to conform with the current period presentation. The Company determined the adjustment is immaterial based on consideration of quantitative and qualitative factors. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the condensed consolidated financial statements, as well as the reported amounts of revenues and expenses during the periods presented. The Company bases its estimates on historical experience and other market-specific or other relevant assumptions that it believes to be reasonable under the circumstances. Estimates are used in several areas including, but not limited to, estimation of variable consideration, estimation of credit losses, standalone selling price allocation included in contracts with multiple performance obligations, goodwill and identifiable intangible assets, stock-based compensation, incremental borrowing rate for operating leases, contingencies, certain inputs into the provision for income taxes, including related reserves, valuation of non-marketable securities, among others. These estimates generally involve complex issues and require judgments, involve the analysis of historical results and prediction of future trends, can require extended periods of time to resolve and are subject to change from period to period. Actual results may differ materially from management’s estimates. Unaudited Interim Condensed Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Securities Act of 1933, as amended, or the Securities Act. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. These unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring accruals that the Company believes are necessary to fairly state the financial position and the results of the Company’s operations and cash flows for interim periods in accordance with GAAP. Interim-period results are not necessarily indicative of results of operations or cash flows for a full year or any subsequent interim period. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. Restricted Cash As of June 30, 2024, the Company had restricted cash balance of $101.5 million, included in cash, cash equivalents and restricted cash on the Company's condensed consolidated balance sheets, of which substantially all was related to cash held as collateral under surety bond requirements related to the intellectual property dispute with TwinStrand Biosciences, Inc. and the University of Washington, as described in Note 8 Commitments and Contingencies - Legal Proceedings to the Company's condensed consolidated financial statements. Non-Marketable Securities The Company acquires certain equity investments in private companies to promote business and strategic objectives. The Company's investments in non-marketable equity securities do not give the Company the ability to control or exercise significant influence over the investees. One of the investees is concluded to be a variable interest entity, or VIE, but the Company is deemed not to be the primary beneficiary as the Company does not have the power to direct the activities that most significantly impact the VIE’s economic performance. The Company's non-marketable equity and other related investments totaled $11.1 million and $8.6 million as of June 30, 2024, and December 31, 2023, respectively, and are included in other assets, net on the accompanying condensed consolidated balance sheets. Non-marketable securities are recorded at cost, subject to periodic impairment reviews and adjustments for observable price changes from orderly transactions. The Company's evaluation of impairment of such non-marketable securities is based on adverse changes in market conditions and the regulatory or economic environment, qualitative and quantitative analysis of the operating performance and financial condition of the investee; changes in operating structure or management of the investee; and additional funding requirements of the investee. As a result of the evaluation, for one of its non-marketable equity security investments, the Company recorded an impairment of $16.6 million and $22.1 million for the three and six months ended June 30, 2023, included in other income (expense), net on the Company's condensed consolidated statements of operations. In addition, in connection with the investment in non-marketable securities purchased by the Company, the Company acquired rights to purchase the investee at a pre-determined price subject to additional adjustments based on the performance of the investee, on or before December 31, 2022. In September 2022, the Company decided not to exercise such rights to purchase the investee and recorded an impairment of $5.3 million for the year ended December 31, 2022, included in other income (expense), net on the Company's condensed consolidated statements of operations. Pursuant to another investment in non-marketable securities purchased by the Company, the Company acquired rights to purchase the investee at a pre-determined price subject to additional adjustments based on the performance of the Company, on or before October 1, 2023, and acquired rights to obtain the exclusive license of the investee's certain technologies. In June 2023, the Company decided not to exercise such rights and recorded an impairment of $7.0 million for the three months ended June 30, 2023, included in other income (expense), net on the Company's condensed consolidated statements of operations. No other impairment or downward adjustments to the carrying value of the Company's non-marketable securities have been otherwise recorded. Concentration of Risk The Company is subject to credit risk from its portfolio of cash equivalents held at one commercial bank and investments in marketable debt securities. The Company limits its exposure to credit losses by investing in money market funds through a U.S. bank with high credit ratings. The Company’s cash may consist of deposits held with banks that may at times exceed federally insured limits, however, its exposure to credit risk in the event of default by the financial institution is limited to the extent of amounts recorded on the condensed consolidated balance sheets. The Company performs evaluations of the relative credit standing of these financial institutions to limit the amount of credit exposure. The Company also invests in investment-grade debt instruments and has policy limits for the amount it can invest in any one type of security, except for securities issued or guaranteed by the U.S. government. The goals of the Company’s investment policy, in order of priority, are as follows: safety and preservation of principal and diversification of risk; liquidity of investments sufficient to meet cash flow requirements; and a competitive after-tax rate of return. Under its investment policy, the Company limits amounts invested in such securities by credit rating, maturity, investment type and issuer, as a result, the Company is not exposed to any significant concentrations of credit risk from these financial instruments. The Company is subject to credit risk from its accounts receivable. The majority of the Company’s accounts receivable arises from the provision of precision oncology services, and development services and other, primarily with biopharmaceutical companies and international laboratory partners, all of which have high credit ratings. The Company has not experienced any material losses related to receivables from individual customers, or groups of customers. The Company does not require collateral. Accounts receivable are recorded net of allowance for credit losses, if any. A significant customer is any biopharmaceutical customer, clinical testing payer, or international laboratory partner that represents 10% or more of the Company’s total revenue or accounts receivable balance. Revenue attributable to each significant customer, including its affiliated entities, as a percentage of the Company’s total revenue, for the respective period, and accounts receivable balance attributable to each significant customers, including its affiliated entities, as a percentage of the Company’s total accounts receivable balance, at the respective condensed consolidated balance sheet date, are as follows:

* less than 10% Accounts Receivable, Net Accounts receivable represent valid claims against commercial and governmental payers, biopharmaceutical companies, research institutes, international laboratory partners and distributors, including unbilled receivables, and royalty payments due from third parties for licensing the Company’s technologies. Unbilled receivables include balances due from biopharmaceutical customers related to development services and other revenues that are recognized upon the achievement of performance-based milestones but prior to the achievement of contractual billing rights. As of June 30, 2024, and December 31, 2023, the Company had unbilled receivables of $5.6 million and $4.9 million, respectively. The Company evaluates the collectability of its accounts receivable based on historical collection trends, the financial condition of payment partners, and external market factors and provides for an allowance for potential credit losses based on management’s best estimate of the amount of probable credit losses. The Company recorded immaterial credit losses related to its accounts receivable for the three and six months ended June 30, 2024, and 2023. Goodwill and Intangible Assets, net Goodwill represents the excess of the purchase price over the fair value of net identifiable assets and liabilities. Goodwill is not amortized but is tested for impairment at least annually during the fourth fiscal quarter, or if circumstances indicate its value may no longer be recoverable. The Company continues to operate in one segment, which is considered to be the sole reporting unit and, therefore, goodwill is tested for impairment at the enterprise level. As of June 30, 2024, there has been no impairment of goodwill. Intangible assets with finite useful lives are carried at cost, net of accumulated amortization. The Company does not have intangible assets with indefinite useful lives other than goodwill. Amortization is recorded on a straight-line basis over the intangible asset's useful life, which is approximately 2—12 years. Leases The Company determines if an arrangement contains a lease at inception. Operating lease right-of-use, or ROU, assets and operating leases liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. ROU assets also include any initial direct costs incurred and any lease payments made at or before the lease commencement date, less lease incentives received or receivable. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the lease liabilities, as the Company's leases generally do not provide an implicit rate. Lease terms may include options to extend or terminate when the Company is reasonably certain the option will be exercised. Lease expense is recognized on a straight-line basis over the lease term. The Company also has lease arrangements with lease and non-lease components. The Company elected the practical expedient not to separate non-lease components from lease components for the Company’s facility leases. The Company also elected to apply the short-term lease measurement and recognition exemption in which ROU assets and lease liabilities are not recognized for leases with terms of 12 months or less. Convertible Senior Notes Convertible senior notes are accounted for as a liability and measured at their amortized cost. Transaction costs related to the issuance of the notes are netted with the liability and are amortized to interest expense over the term of the notes, using an effective interest rate method. Revenue Recognition The Company derives revenue from the provision of precision oncology testing services, as well as from development services and other. Precision oncology testing revenue includes amounts derived from the delivery of the Company’s precision oncology tests, including those tests delivered by labs operated by our strategic partners. Development services include companion diagnostic development and regulatory approval, clinical study setup, monitoring and maintenance, testing development and support, GuardantConnect and GuardantINFORM. Other revenue includes amounts derived from licensing the Company's technologies, and kit fulfillment. The Company currently receives payments from third-party commercial and governmental payers, certain hospitals and oncology centers and individual patients, as well as biopharmaceutical companies, research institutes, international laboratory partners and distributors. Revenues are recognized when control of services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. FASB ASC Topic 606, Revenue from Contracts with Customers, provides for a five-step model that includes identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations, and recognizing revenue when, or as, an entity satisfies a performance obligation. Precision oncology testing The Company recognizes revenue from the sale of its precision oncology tests for clinical customers, including certain hospitals, cancer centers, other institutions and patients, at the time results of the test are reported to physicians. Most precision oncology tests requested by clinical customers are sold without a written agreement; however, the Company determines an implied contract exists with its clinical customers. The Company identifies each sale of its test to a clinical customer as a single performance obligation. With the exception of certain limited contracted arrangements with insurance carriers and other institutions where the transaction price is fixed, a stated contract price does not exist and the transaction price for each implied contract with clinical customers represents variable consideration. The Company estimates the variable consideration under the portfolio approach and considers the historical reimbursement data from third-party commercial and governmental payers and patients, as well as known or anticipated reimbursement trends not reflected in the historical data. The Company monitors the estimated amount to be collected in the portfolio at each reporting period based on actual cash collections in order to assess whether a revision to the estimate is required. Both the estimate and any subsequent revision contain uncertainty and require the use of significant judgment in the estimation of the variable consideration and application of the constraint for such variable consideration. The Company analyzes its actual cash collections over the expected reimbursement period and compares it with the estimated variable consideration for each portfolio and any difference is recognized as an adjustment to estimated revenue after the expected reimbursement period, subject to assessment of the risk of future revenue reversal. Revenue from sales of precision oncology tests to biopharmaceutical customers are based on a negotiated price per test or on the basis of an agreement to provide certain testing volume over a defined period. The Company identifies its promise to transfer a series of distinct tests to biopharmaceutical customers as a single performance obligation. Precision oncology tests to biopharmaceutical customers are generally billed at a fixed price for each test performed. For agreements involving testing volume to be satisfied over a defined period, revenue is recognized over time based on the number of tests performed as the performance obligation is satisfied over time. Results of the Company’s precision oncology services are delivered electronically, and as such there are no shipping or handling fees incurred by the Company or billed to customers. Development services and other The Company performs development services for its biopharmaceutical customers utilizing its precision oncology information platform. Development services typically represent a single performance obligation as the Company performs a significant integration service, such as analytical validation and regulatory submissions. The individual promises are not separately identifiable from other promises in the contracts and, therefore, are not distinct. However, under certain contracts, a biopharmaceutical customer may engage the Company for multiple distinct development services which are both capable of being distinct and separately identifiable from other promises in the contracts and, therefore, distinct performance obligations. The Company collaborates with biopharmaceutical companies in the development of new drugs. As part of these collaborations, the Company provides services related to regulatory filings to support companion diagnostic device submissions for the Company’s testing panels. Under these collaborations, the Company generates revenue from achievement of milestones, as well as provision of on-going support. For the companion diagnostic development and regulatory approval services performed, the Company is compensated through a combination of an upfront fee and performance-based, non-refundable regulatory and other developmental milestone payments. The transaction price of these contracts typically represents variable consideration. Application of the constraint for variable consideration to milestone payments is an area that requires significant judgment. The Company evaluates factors such as the scientific, clinical, regulatory, commercial, and other risks that must be managed to achieve the respective milestone and the level of effort and investment required to achieve the respective milestone. In making this assessment, the Company considers its historical experience with similar milestones, the degree of complexity and uncertainty associated with each milestone, and whether achievement of the milestone is dependent on parties other than the Company. The constraint for variable consideration is applied such that it is probable a significant reversal of revenue will not occur when the uncertainty associated with the contingency is resolved. Application of the constraint for variable consideration is assessed and updated at each reporting period as a revision to the estimated transaction price. The Company recognizes companion diagnostic development and regulatory approval services revenue over the period in which biopharmaceutical research and development services are provided. Specifically, the Company recognizes revenue using an input method to measure progress, utilizing costs incurred to-date relative to total expected costs as its measure of progress. The Company assesses the changes to the total expected cost estimates as well as any incremental fees negotiated resulting from changes to the scope of the original contract in determining the revenue recognition at each reporting period. For development of new products or services under these arrangements, costs incurred before technological feasibility is reached are included as research and development expenses in the Company’s condensed consolidated statements of operations, while costs incurred thereafter are recorded as cost of development services and other. The Company also recognizes revenue from other development services, in addition to companion diagnostic development and regulatory approval services noted above, such as clinical study setup, monitoring and maintenance, testing development and support, GuardantConnect and GuardantINFORM. These revenues are generally recognized over time based on an input method to measure progress in the period when the associated services have been performed. In addition, the Company licenses its digital sequencing technologies to its domestic customers and international laboratory partners. For the licensed technology, the Company is compensated through royalty-based payments, non-refundable upfront payments, guaranteed minimum payments, and/or sample milestone payments. Depending on the nature of the technology licensing arrangements, and considering factors including but not limited to enforceable right to payment and payment terms, and if an asset with alternative use is created, these revenues are recognized in the period when royalty-bearing sales occur, when the technology transfer is complete, or over the technology transfer period. Other revenue also includes kit fulfillment, which is recognized when such products are delivered. For the three and six months ended June 30, 2024, the Company recorded $15.2 million and $24.9 million, respectively, as revenue related to performance obligations satisfied in prior periods. For the three and six months ended June 30, 2023, the Company recorded $2.8 million and $4.5 million, respectively, as revenue related to performance obligations satisfied in prior periods. Contracts with multiple performance obligations Contracts with biopharmaceutical customers and international laboratory partners may include multiple distinct performance obligations, such as provision of precision oncology testing, the above-mentioned development services, and digital sequencing technology licensing, among others. The Company evaluates the terms and conditions included within its contracts with biopharmaceutical customers and international laboratory partners to ensure appropriate revenue recognition, including whether services are considered distinct performance obligations that should be accounted for separately versus together. The Company first identifies material promises, in contrast to immaterial promises or administrative tasks, under the contract, and then evaluates whether these promises are both capable of being distinct and distinct within the context of the contract. In assessing whether a promised service is capable of being distinct, the Company considers whether the customer could benefit from the service either on its own or together with other resources that are readily available to the customer, including factors such as the research, development, and commercialization capabilities of a third party as well as the availability of the associated expertise in the general marketplace. In assessing whether a promised service is distinct within the context of the contract, the Company considers whether it provides a significant integration of the services, whether the services significantly modify or customize one another, or whether the services are highly interdependent or interrelated. For contracts with multiple performance obligations, the transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. The Company determines standalone selling price by considering the historical selling price of these performance obligations in similar transactions as well as other factors, including, but not limited to, the price that customers in the market would be willing to pay, competitive pricing of other vendors, industry publications and current pricing practices, and expected costs of satisfying each performance obligation plus appropriate margin; or by using the residual approach if standalone selling price is not observable, by reference to the total transaction price less the sum of the observable standalone selling prices of other performance obligations promised in the contract. Deferred revenue Deferred revenue, which is a contract liability, consists primarily of payments received in advance of revenue recognition from contracts with customers. For example, development services and other contracts with biopharmaceutical customers often contain upfront payments which results in the recording of deferred revenue to the extent cash is received prior to the Company's performance of the related services. Contract liabilities are relieved as the Company performs its obligations under the contract and revenue is consequently recognized. As of June 30, 2024 and December 31, 2023, the deferred revenue balance was $35.4 million and $22.9 million, respectively, of which $6.0 million and $5.0 million was considered long-term and recorded within other long-term liabilities on the accompanying condensed consolidated balance sheets. Revenue recognized in the six months ended June 30, 2024 that was included in the deferred revenue balance as of December 31, 2023 was $9.3 million, and revenue recognized in the six months ended June 30, 2023 that was included in the deferred revenue balance as of December 31, 2022 was $11.8 million, respectively. Transaction price allocated to the remaining performance obligations Transaction price allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes deferred revenue and non-cancelable amounts that will be invoiced and recognized as revenues in future periods. The Company expects to recognize substantially all of the remaining transaction price in the next 1-2 years. Costs of Precision Oncology Testing Cost of precision oncology testing generally consists of cost of materials, cost of labor, including bonus, benefit and stock-based compensation, equipment and infrastructure expenses associated with processing test samples (including sample accessioning, library preparation, sequencing, and quality control analyses), freight, curation of test results for physicians, phlebotomy, and license fees due to third parties. Infrastructure expenses include depreciation of laboratory equipment, lease costs, amortization of leasehold improvements, and information technology costs. Costs associated with performing the Company’s tests are recorded as the tests are performed regardless of whether revenue was recognized with respect to that test. Cost of Development Services and Other Cost of development services and other primarily includes costs incurred for the performance of development services requested by the Company’s biopharmaceutical customers, and costs associated with the Company's partnership agreements and delivery of screening tests. For development of new products, costs incurred before technological feasibility has been achieved are reported as research and development expenses, while costs incurred thereafter are reported as cost of development services and other. Research and Development Expenses Research and development expenses consist of costs incurred to develop technology and include salaries and benefits including stock-based compensation, reagents and supplies used in research and development laboratory work, infrastructure expenses, including facility occupancy and information technology costs, contract services, other outside costs and costs to develop the Company's technology capabilities. Research and development expenses also include costs related to activities performed under contracts with biopharmaceutical companies before technological feasibility has been achieved. Research and development costs are expensed as incurred. Payments made prior to the receipt of goods or services to be used in research and development are deferred and recognized as expense in the period in which the related goods are received or services are rendered. Costs to develop technology capabilities are recorded as research and development expenses unless they meet the criteria to be capitalized as internal-use software costs. Stock-Based Compensation Stock-based compensation related to stock options granted to the Company’s employees, directors and nonemployees is measured at the grant date based on the fair value of the award. The fair value is recognized as expense over the requisite service period, which is generally the vesting period of the respective awards. Compensation expense for stock options with performance metrics is calculated based upon expected achievement of the metrics specified in the grant. The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options granted under the 2012 Stock Plan (as amended and restated), or the 2012 Plan, the 2018 Incentive Award Plan, or the 2018 Plan, the 2023 Employment Inducement Incentive Award Plan, or the 2023 Plan, and stock purchase rights granted under the 2018 Employee Stock Purchase Plan. The Black-Scholes option-pricing model requires assumptions to be made related to the expected term of an award, expected volatility, risk-free rate and expected dividend yield. The Company measures the grant date fair value of its service-based and performance-based restricted stock units issued to employees and non-employees based on the closing market price of the common stock on the date of grant. For restricted stock units with only service-based vesting conditions, compensation expense is recognized in the Company’s condensed consolidated statement of operations on a straight-line basis over the requisite service period. Compensation expense for restricted stock units with performance metrics, or PSUs, is calculated based upon expected achievement of the metrics specified in the grant, and is recognized in the Company’s condensed consolidated statement of operations using an accelerated attribution model over the requisite service period for each separately vesting portion of the award. No stock-based compensation expense is recorded for PSUs, unless it is determined to be probable that the related performance metrics will be met. In addition, a cumulative adjustment will be recorded in the period when the probability of achieving the related performance metrics is adjusted. Any PSUs that remain unvested at the end of the performance period will be forfeited. Forfeitures are accounted for as they occur. Net Loss Per Share The Company calculates basic net loss per share by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period. The diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period determined using the treasury stock method or the as-if converted method, as appropriate. For purposes of this calculation, stock options, restricted stock units, shares issuable pursuant to the employee stock purchase plan, and contingently issuable shares under the convertible senior notes are considered common stock equivalents but have been excluded from the calculation of diluted net loss per share as their effect is anti-dilutive. New Accounting Pronouncements Not Yet Adopted In November 2023, the Financial Accounting Standards Board, or FASB, issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires an enhanced disclosure of significant segment expenses on an annual and interim basis. This guidance will be effective for the annual reporting periods beginning the year ended December 31, 2024, and for interim reporting periods beginning January 1, 2025, with early adoption permitted, and should be applied retrospectively. The Company expects to provide required disclosures upon the effective date. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which amended existing income tax disclosure guidance, primarily requiring more detailed disclosures on the effective tax rate reconciliation and income taxes paid. This guidance will be effective for annual reporting periods beginning the year ended December 31, 2025, with early adoption permitted and can be applied on either a prospective or retroactive basis. The Company expects to provide required disclosures upon the effective date.
