Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The Company's consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain prior period balances have been reclassified to conform to current period presentation of the Company’s consolidated financial statements and accompanying notes. Such reclassifications have no effect on previously reported results of operations, accumulated deficit, subtotals of operating, investing or financing cash flows or consolidated balance sheet totals; however, for the period December 31, 2021, the Company reclassified $4.0 million of short-term investments from the prepaid expenses and other current assets caption in the consolidated balance sheets. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant items subject to such estimates include: revenue recognition; write-down of supplies; useful lives of property and equipment; the recoverability of long-lived assets; the incremental borrowing rates for leases; accounting for acquisitions; the estimation of the fair value of intangible assets and contingent consideration; stock based compensation; income tax uncertainties, including a valuation allowance for deferred tax assets; credit related losses on investments; and allowance for credit losses and contingencies. The Company bases these estimates on historical and anticipated results, trends, and various other assumptions that the Company believes are reasonable under the circumstances, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities and recorded revenue and expenses that are not readily apparent from other sources. Actual results could differ from those estimates and assumptions. Liquidity The Company has incurred net losses since its inception and as of December 31, 2022, the Company had an accumulated deficit of $393.7 million. The Company believes its cash and cash equivalents and short-term investments of $178.9 million as of December 31, 2022, and its revenue from sales in 2023 will be sufficient to meet its anticipated cash requirements through at least February 2024. In February 2021, the Company issued and sold 8,547,297 shares of common stock in a registered public offering, including 1,114,864 shares issued and sold upon the underwriters' exercise in full of their option to purchase additional shares, at a price to the public of $74.00 per share. The Company's net proceeds from the offering were approximately $593.8 million, after deducting underwriting commissions and offering expenses of $38.7 million. In August 2020, the Company issued and sold 6,900,000 shares of common stock in a registered public offering, including 900,000 shares issued and sold upon the underwriters' exercise in full of their option to purchase additional shares, at a price to the public of $30 per share. The Company's net proceeds from the offering were approximately $193.8 million, after deducting underwriting commissions and offering expenses of $13.2 million. If the Company is not able to generate cash proceeds from revenue sufficient to satisfy its cash obligations, the Company will need to finance future cash needs primarily through public or private equity offerings, debt financings, borrowings or strategic collaborations or licensing arrangements. If the Company is not able to secure additional funding when needed, on acceptable terms, it may have to delay, reduce the scope of or eliminate one or more research and development programs or selling and marketing initiatives which may have a material adverse effect on the Company's business, results of operations, financial condition and/or its ability to fund its scheduled obligations on a timely basis or at all. Concentrations of Credit Risk and Other Risks and Uncertainties The worldwide spread of coronavirus, or COVID-19, has created significant uncertainty in the global economy. There have been no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have. As a result, the ultimate impact of COVID-19 and the extent to which COVID-19 impacts the Company’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict. If the financial markets or the overall economy are impacted for an extended period, the Company’s liquidity, revenue, supplies, goodwill and intangibles may be adversely affected. The Company considers the effects, to the extent knowable, of the COVID-19 pandemic in developing its estimates. The majority of the Company’s cash and cash equivalents are deposited with one major financial institution in the United States. Deposits in this institution may exceed the amount of insurance provided on such deposits. The Company has not realized any losses on its deposits of cash and cash equivalents other than exchange rate losses related to foreign currency denominated accounts. Several of the components of the Company's sample collection kits and test reagents, and the nCounter Analysis system and related diagnostic kits, 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, suffer a possible loss of revenue, or incur higher costs, any of which could adversely affect its operating results. Through December 31, 2022, the Company has derived most of its revenue from the sale of Decipher and Afirma testing. To date, Decipher and Afirma testing have been delivered primarily to physicians in the United States. The Company is also subject to credit risk from its accounts receivable related to its sales. Credit risk for accounts receivable from testing revenue is incorporated in testing revenue accrual rates as the Company assesses historical collection rates and current developments to determine accrual rates and amounts the Company will ultimately collect. The Company generally does not perform evaluations of customers’ financial condition for testing revenue and generally does not require collateral. The Company assesses credit risk and the amount of accounts receivable the Company will ultimately collect for product, biopharmaceutical and other revenue based on collection history, current developments and credit worthiness of the customer. The estimate of credit losses is not material at December 31, 2022. The Company's total third-party payers and other customers in excess of 10% of total revenue and their related revenue as a percentage of total revenue were as follows: Year Ended December 31, 2022 2021 2020 Medicare 31 % 30 % 24 % UnitedHealthcare 10 % 10 % 11 % 41 % 40 % 35 % The Company's significant third-party payers in excess of 10% of total accounts receivable and their related accounts receivable balance as a percentage of total accounts receivable were as follows: As of December 31, 2022 2021 Medicare 14 % 12 % UnitedHealthcare 10 % 9 % Cash Equivalents The Company considers demand deposits in a bank, money market funds and highly liquid investments with an original maturity of 90 days or less to be cash equivalents. Short-Term Investments The Company's short-term investments consist of U.S. treasury securities and time deposits with a bank with maturities at the time of purchase that were between 90 days and one year. The Company classifies these investments as held-to-maturity debt securities, which are reported at amortized cost. Discounts or premiums from the purchase of the securities are recognized as a component of interest income in other income (loss), net in the consolidated statements of operations. Investments are initially recorded net of an allowance for expected credit losses, if any, which are remeasured each period and any impairments are recognized as an expense. Unrealized gains and losses are not recognized in income. As of both December 31, 2022 and December 31, 2021, no allowances for expected credit losses had been recorded and there have been no impairment or credit losses on the Company's short term investments. Restricted Cash The Company had deposits of $0.7 million included in long-term assets as of both December 31, 2022 and December 31, 2021, restricted from withdrawal and held by banks in the form of collateral for irrevocable standby letters of credit held as security for the Company's leases. Acquisitions The Company first determines whether a set of assets acquired and liabilities assumed constitute a business and should be accounted for as a business combination. If the assets acquired are not a business, the Company accounts for the transaction as an asset acquisition. Business combinations are accounted for by using the acquisition method of accounting. Under the acquisition method, assets acquired, and liabilities assumed are recorded at their respective fair values as of the acquisition date in the Company's consolidated financial statements. The estimated fair value of intangible assets acquired are based on discounted cash flows utilizing certain assumptions including revenues (such as projected testing volumes, growth rates), discount rates and expected economic life/obsolescence factors of the respective assets. The excess of the fair value of consideration transferred over the fair value of the net assets acquired is recorded as goodwill. Contingent consideration obligations incurred in connection with a business combination are recorded at fair value on the acquisition date and remeasured at each subsequent reporting period until the related contingencies are resolved, with the resulting changes in fair value recorded in general and administrative expense in the consolidated statements of operations. Equity Investment In July 2020, the Company invested $1.0 million in the preferred stock of MAVIDx, Inc., or MAVIDx, a company developing a diagnostic platform for infectious diseases testing. MAVIDx is a variable interest entity, or VIE, and the Company's investment is a variable interest. The Company has determined that it is not the primary beneficiary of the VIE due to the fact that the Company does not have the power to direct the activities that impact the economic performance of MAVIDx or the obligation to fund its operations with ongoing financial support or contributions. MAVIDx is a private company and its equity securities are not traded or quoted in any securities exchange or in the over-the-counter market, and therefore does not have a readily determinable fair value. As such, the Company has elected to measure its investment in the preferred stock at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar equity financings of MAVIDx, in accordance with Accounting Standards Codification, or ASC 321, Investments—Equity Securities . Based on the fourth quarter of 2020 operating performance of MAVIDx and the volatile nature of the market in which it operates, the Company determined that the investment in MAVIDx was fully impaired as of December 31, 2020. As a result, an impairment loss of $1.0 million was recorded in the fourth quarter of 2020 and is included in general and administrative expense in the consolidated statements of operations. Supplies and Inventory Supplies consists of materials and reagents consumed in the performance of testing services. Inventory consists of raw materials consumed in the contract manufacturing process as well as finished and semi-finished components used in the assembly of diagnostic kits related to product sales. Inventory is stated at the lower of cost or net realizable value on a weighted average basis. The Company periodically analyzes supply and inventory levels and expiration dates, and writes down supply or inventory that has become obsolete, that has a cost basis in excess of its net realizable value, or in excess of expected sales requirements as cost of revenue. The Company records an allowance for excess or obsolete supplies and inventory using an estimate based on historical trends and evaluation of near-term expirations. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally between three Leases The Company determines if an arrangement is, or contains, a lease at inception. Operating leases are included in right-of-use assets - operating leases and operating lease liabilities in the consolidated balance sheets, representing the right to use an underlying asset for the lease term and the obligation to make lease payments arising from the lease. Right-of-use, or ROU, assets and lease liabilities are recognized at commencement based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments. The ROU assets also includes any lease payments made and is adjusted for lease incentives. Lease terms may include options to extend or terminate the lease which are recognized when it is reasonably certain that the Company will exercise that option. Lease expense is recognized on a straight-line basis over the lease terms. Lease and non-lease components are accounted for as a single lease component. Financing leases are immaterial and are included in property and equipment, net and other liabilities in the consolidated balance sheets. Leases with terms of 12 months or less are not recorded on our balance sheet. Finite-lived Intangible Assets Finite-lived intangible assets consist of intangible assets acquired as part of business combinations. The Company amortizes finite-lived intangible assets using the straight-line method over their estimated useful lives of 4 to 15 years, based on management's estimate of the period over which their economic benefits will be realized, product life and patent life. The Company tests these finite-lived intangible assets for impairment when events or circumstances indicate a reduction in the fair value below their carrying amounts. The Company recorded a $3.3 million impairment charge for the year ended December 31, 2022 and no impairment charge for the years ended December 31, 2021 or 2020. See Note 5 Balance Sheet Components for more information on the 2022 impairment testing. Indefinite-lived Intangible Assets Indefinite-lived intangible assets consist of in-process research and development, or IPR&D, acquired as part of business combinations. The IPR&D is not amortized until it becomes commercially viable and placed in service. At the time when the intangible assets are placed in service the Company will determine a useful life. The Company also tests these indefinite-lived intangible assets for impairment when events or circumstances indicate a reduction in the fair value below their carrying amounts. There was no impairment of indefinite-lived intangible assets for the years ended December 31, 2022, 2021 or 2020. Goodwill Goodwill, is reviewed for impairment on an annual basis or more frequently if events or circumstances indicate that it may be impaired. The Company's goodwill evaluation is based on both qualitative and quantitative assessments regarding the fair value of goodwill relative to its carrying value. The Company has determined that it operates in a single segment and has a single reporting unit associated with the development and commercialization of diagnostic products. In the event the Company determines that it is more likely than not the carrying value of the reporting unit is higher than its fair value, quantitative testing is performed comparing recorded values to estimated fair values. If impairment is present, the impairment loss is measured as the excess of the recorded goodwill over its implied fair value. There was no impairment of goodwill for the years ended December 31, 2022, 2021 or 2020. Fair Value of Financial Instruments The carrying amounts of certain financial instruments including cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate fair value due to their relatively short maturities. See Note 6. Fair Value Measurements for further information on the fair value of the Company’s financial instruments. Revenue Recognition The Company recognizes revenue in accordance with the provisions of ASC 606, Revenue from Contracts with Customers , or ASC 606. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue when the performance obligations have been satisfied. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. Performance obligations are considered satisfied once the Company has completed a service or transferred control of a product to the customer. In arrangements involving more than one service or good, each required service or good is evaluated to determine whether it qualifies as a distinct performance obligation based on whether (i) the customer can benefit from the service or good either on its own or together with other resources that are readily available and (ii) the service or good is separately identifiable from other promises in the contract. The consideration under the arrangement is then allocated to each separate distinct performance obligation based on its respective relative stand-alone selling price. The estimated selling price of each deliverable reflects the Company's best estimate of what the selling price would be if the deliverable was regularly sold by the Company on a stand-alone basis or using an adjusted market assessment approach if selling price on a stand-alone basis is not available. The consideration allocated to each distinct performance obligation is recognized as revenue when control is transferred which may be at a point in time or over time. Testing Revenue The Company bills for testing services at the time of test completion as defined by the delivery of test results. The Company recognizes revenue based on estimates of the amount that will ultimately be realized. In determining the amount to accrue for a delivered test, the Company considers factors such as payment history, payer coverage, whether there is a reimbursement contract between the payer and the Company, payment as a percentage of agreed upon rate (if applicable), amount paid per test and any current developments or changes that could impact reimbursement. These estimates require significant judgment by management. Actual results could differ from those estimates and assumptions. The Company has changed its revenue estimates due to actual and anticipated cash collections for tests delivered in prior years and recognized immaterial changes in revenue, loss from operations and basic and diluted net loss per share for the years ended December 31, 2022, 2021 and 2020. Product Revenue The Company's products consist of the Prosigna breast cancer assay, the nCounter Analysis System and related diagnostic kits. Product revenue from diagnostic kits is generally recognized upon shipment. Product revenue from instruments is generally recognized when the instrument is ready for use by the end customer. Shipping and handling costs incurred for product shipments are included in product revenue. Revenue is presented net of the taxes that are collected from customers and remitted to governmental authorities. Biopharmaceutical and Other Revenue The Company enters into arrangements for biopharmaceutical research and development, commercialization, contract manufacturing and development, and testing services which are classified under biopharmaceutical and other revenue. Such arrangements may require the Company to deliver various rights, manufactured diagnostic test kits, services and/or samples, including intellectual property rights/licenses, biopharmaceutical research and development services, and/or commercialization services. The Company receives consideration in the form of upfront license fees; payments on delivery of data, test results or manufactured products; costs of service plus margin; and development and commercial performance milestone payments. The Company develops estimates and assumptions that require judgment to determine the underlying stand-alone selling price for each performance obligation which determines how the transaction price is allocated among the performance obligations. The estimation of the stand-alone selling price may include independent evidence of market price, forecasted revenue or costs, development timelines, discount rates, and probabilities of technical and regulatory success. The Company evaluates each performance obligation to determine if the obligation can be satisfied at a point in time or over time, and it measures the services delivered to the collaborative partner which are periodically reviewed based on the progress of the related program. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time. The effect of any change made to an estimated input component and, therefore revenue or expense recognized, would be recorded as a change in estimate. In addition, variable consideration must be evaluated to determine if it is constrained and, therefore, excluded from the transaction price. At the inception of each arrangement that includes milestone payments (variable consideration), the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price. Milestone payments that are not within either party’s control, such as non-operational developmental and regulatory approvals, are generally not considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company re-evaluates the probability of achievement of milestones that are within either party’s control, such as operational developmental milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and earnings in the period of adjustment. Revisions to the Company’s estimate of the transaction price may also result in negative revenue and earnings in the period of adjustment. One collaboration arrangement with milestone payments falls under the scope of ASC Topic 808, Collaborative Arrangements , or ASC 808. These milestone payments are recognized in the same manner as milestone payments from customers and are classified under biopharmaceutical and other revenue. Accounts receivable from biopharmaceutical and other revenue was $9.3 million and $11.6 million at December 31, 2022 and 2021, respectively. There was $2.6 million and $5.0 million of deferred revenue related to these agreements at December 31, 2022 and 2021, respectively. Revenue included in biopharmaceutical and other revenue for the years ended December 31, 2022, 2021 and 2020 was as follows (in thousands of dollars): Year Ended December 31, 2022 2021 2020 Biopharmaceutical revenue $ 26,341 $ 12,613 $ 5,668 Contract manufacturing and testing 7,019 3,255 — Collaboration milestones — 4,000 — Total $ 33,360 $ 19,868 $ 5,668 Cost of Testing Revenue The components of the Company's cost of testing services are laboratory expenses, sample collection expenses, compensation expense, license fees and royalties, depreciation, other expenses such as equipment and laboratory supplies, and allocations of facility and information technology expenses. Costs associated with performing tests are expensed as the test is processed regardless of whether and when revenue is recognized with respect to that test. Cost of Product Revenue Cost of product revenue consists primarily of costs of purchasing instruments and diagnostic kits from third-party contract manufacturers, installation, service and packaging and delivery costs, and the Company's internal labor expenses. In addition, cost of product includes royalty costs for licensed technologies included in the Company's products. Cost of product revenue for instruments and diagnostic kits is recognized in the period the related revenue is recognized. Shipping and handling costs incurred for product shipments are included in cost of product in the consolidated statements of operations. Cost of Biopharmaceutical and Other Revenue Cost of biopharmaceutical and other revenue consists of costs of performing activities under arrangements that require the Company to perform biopharmaceutical research and development, commercialization, contract manufacturing and contract testing services on behalf of a customer. Research and Development Research and development expenses include expenses incurred to develop the Company's technology, collect clinical samples and conduct clinical studies to develop and support its products. These expenses consist of compensation expenses, direct research and development expenses such as laboratory supplies and costs associated with setting up and conducting clinical studies at domestic and international sites, professional fees, depreciation and amortization, other miscellaneous expenses and allocation of facility and information technology expenses. The Company expenses all research and development costs in the periods in which they are incurred. Income Taxes The Company accounts for income taxes under the liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The Company assesses all material positions taken in any income tax return, including all significant uncertain positions, in all tax years that are still subject to assessment or challenge by relevant taxing authorities. The Company's assessment of an uncertain tax position begins with the initial determination of the position's sustainability and is measured at the largest amount of benefit that is more-likely-than-not of being realized upon ultimate settlement. As of each balance sheet date, unresolved uncertain tax positions must be reassessed, and the Company will determine whether (i) the factors underlying the sustainability assertion have changed and (ii) the amount of the recognized tax benefit is still appropriate. The recognition and measurement of tax benefits requires significant judgment. Judgments concerning the recognition and measurement of a tax benefit may change as new information becomes available. Stock-based Compensation Stock-based compensation expense for stock options issued to employees and non-employees is measured based on the grant-date fair value of the award. The fair value of each stock option is estimated on the date of grant using the Black-Scholes option-pricing model. Stock-based compensation expense for restricted stock units, or RSUs, is measured based on the fair value of the award, which is determined based upon the closing price of the Company’s common stock on the date of the grant. The Company grants performance-based stock units, or PSUs, to certain employees which vest upon the achievement of certain performance conditions, subject to the employees’ continued service with the Company. The probability of vesting is assessed at each reporting period and compensation cost is adjusted based on this probability assessment. The Company recognizes compensation costs on a straight-line basis for all employee stock-based compensation awards that are expected to vest over the requisite service period of the awards, which is generally the awards' vesting period. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Net Loss per Common Share Basic net loss per common share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration of common stock equivalents. Diluted net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common share equivalents outstanding for the period determined using the treasury stock method. Potentially dilutive securities consisting of options to purchase common stock, RSUs, PSUs and shares subject to purchase under the Company's employee stock purchase plan are considered to be common stock equivalents and were excluded from the calculation of diluted net loss per common share because their effect would be anti-dilutive for all periods presented. French Research Tax Credits The French research tax credits (crédit d’impôt recherche or CIR) are generated by the Company’s wholly owned subsidiary, Veracyte SAS, in connection with its research efforts performed in Marseille, France. The Company recognizes other income from the CIR over time based on when the research and development expenses are incurred. As of December 31, 2022, $4.8 million of CIR are recorded in prepaids and other current assets on the consolidated balance sheets and $3.5 million is included in other assets. Foreign Currency Translation The functional currency of the Company’s foreign subsidiary, Veracyte SAS, is the Euro. Assets and liabilities denominated in foreign currencies are translated to U.S. dollars using the exchange rates at the balance sheet date. Foreign currency translation adjustments are recorded as a component of accumulated other comprehensive income (loss) within stockholders’ equity. Revenues and expenses from the Company’s foreign subsidiaries are translated using the monthly average exchange rates in effect during the period in which the transactions occur. Foreign currency transaction gains and losses are recorded in other income, net, on the consolidated statements of operations. Comprehensive Loss Comprehensive loss is the change in stockholders’ equity from transactions and other events and circumstances other than those resulting from investments by stockholders and distributions to stockholders. The Company's comprehensive loss includes our net loss and gains and losses from the foreign currency translation of the assets and liabilities of our foreign subsidiaries. Segment Reporting The chief operating decision maker for the Company is the Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of allocating resources and assessing financial performance. The Company has a single reporting unit associated with the development and commercialization of diagnostic products and biopharmaceutical services. Revenue by geographic region based on the customer billing address was as follows (in thousands): Year Ended December 31, 2022 2021 2020 United States $ 262,923 $ 200,982 $ 109,614 International 33,613 18,532 7,869 Total revenue $ 296,536 $ 219,514 $ 117,483 Substantially all of the Company’s long-lived assets were located in the United States as of December 31, 2022 and 2021.
