Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Description of Business And Basis of Presentation | 1. Description of Business and Basis of Presentation Description of Business Singular Genomics Systems, Inc. (the “Company”) is a life science technology company that is leveraging novel next generation sequencing (“NGS”) and multiomics technology to build products that are designed to empower researchers and clinicians to advance science and medicine. The Company developed a novel and proprietary NGS technology, which it refers to as its “Sequencing Engine”. This Sequencing Engine is the foundational platform technology that forms the basis of the Company’s products in development. The Company is currently developing two integrated solutions that are purpose built to target specific applications. Its first integrated solution is targeted at the NGS market and comprises an instrument (the “G4 Instrument”) and an associated menu of consumable kits, which is referred to collectively as the G4 Integrated Solution. The G4 Instrument is a bench top next generation sequencer designed to produce fast and accurate genetic sequencing results. The integrated purpose built kits that run on the G4 Instrument address specific applications in fast growing markets including oncology and immune profiling. The Company’s second integrated solution in development comprises an instrument (the “PX Instrument”) and an associated menu of consumable kits, which is referred to collectively as the PX Integrated Solution. Leveraging sequencing as a universal readout, the PX Integrated Solution combines single cell analysis, spatial analysis, genomics and proteomics in one integrated instrument providing a versatile multiomics solution. The Company was incorporated in the state of Delaware in June 2016 and has its principal operations in La Jolla, California. Initial Public Offering On June 1, 2021, the Company completed its initial public offering ("IPO") in which it sold 11,730,000 shares of common stock (which included 1,530,000 shares that were sold pursuant to the full exercise of the IPO underwriters’ option to purchase additional shares) at a public offering price of $ 22.00 per share. The Company received net proceeds of approximately $ 237.2 million after deducting offering costs, underwriting discounts, and commissions of $ 20.9 million. Concurrent with the completion of the IPO: 38,826,388 outstanding shares of convertible preferred stock converted into an equivalent number of shares of common stock; outstanding principal and interest amount of convertible promissory notes (the "2021 Notes") converted into 7,531,777 shares of the Company's common stock; a warrant to purchase 129,156 shares of convertible preferred stock was adjusted into a warrant to purchase an equivalent number of shares of the Company's common stock. Liquidity and Capital Resources The Company has experienced net losses since inception and, as of June 30, 2021 and December 31, 2020, had an accumulated deficit of $ 114.5 million and $ 53.1 million , respectively. The Company has a limited operating history and the revenue and income potential of the Company’s business are unproven. From incorporation in June 2016 through June 30, 2021, substantially all of the Company’s operations have been funded by the sales of equity securities and issuances of debt. As of June 30, 2021, the Company had cash and cash equivalents and short-term investments totaling, in aggregate, $ 371.7 million . Management expects to continue to incur significant expenses for the foreseeable future and to incur operating losses in the near term while the Company makes investments to support its anticipated growth. The Company cannot be certain that it will ever be profitable or generate positive cash flow from operating activities or that, if it achieves profitability, it will be able to sustain it. The Company believes that its cash and cash equivalents balance as of June 30, 2021 provides sufficient capital resources to continue its operations for at least 12 months from the issuance date of the accompanying unaudited condensed financial statements. Basis of Presentation and Use of Estimates The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures required by GAAP for annual financial statements have been omitted. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Interim financial results are not necessarily indicative of results anticipated for the full year. The preparation of the Company’s unaudited condensed financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities in the Company’s unaudited condensed financial statements and accompanying notes. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may significantly differ from these estimates and assumptions. Significant estimates and assumptions include the useful lives of property and equipment, the fair value of warrant liabilities, the fair value of the Company’s preferred and common stock and stock-based compensation and the fair value of the 2021 Notes. Impact of the COVID-19 Pandemic The Company is continuing to assess the impact of the COVID-19 pandemic on its current and future business and operations, as well as on the Company’s industry and the healthcare system. Any of the foregoing could harm the Company’s operations and the Company cannot anticipate all the ways in which it could be adversely impacted by health epidemics such as COVID-19. |

Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Segment Information Operating 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 singular focus is the development and eventual commercialization of proprietary sequencing solutions. The Company views its operations and manages its business in one operating and reporting segment. The Company’s long-lived assets are located in the United States. Cash, Cash Equivalents and Restricted Cash Cash and Cash Equivalents Cash and cash equivalents include cash readily available in checking, savings, money market and sweep accounts. The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Restricted Cash Restricted cash is held in a separate restricted bank account as the collateral for the security deposits on three executed lease agreements and the collateral on the Company’s corporate credit card program. The Company has classified these deposits as long-term restricted cash on its balance sheets. The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the balance sheets that sum to the total of the same such amounts shown in the statements of the cash flows as of June 30, 2021 and December 31, 2020 (in thousands): June 30, December 31, Cash and cash equivalents $ 257,268 $ 11,688 Restricted cash 687 482 Total $ 257,955 $ 12,170 Concentration of Credit Risk Financial instruments, which potentially subject the Company to a concentration of credit risk, consist primarily of cash, cash equivalents and short-term investments. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. Short-Term Investments As of June 30, 2021 and December 31, 2020 , short-term investments primarily consisted of corporate debt securities, and asset backed securities. The Company classifies all short-term investments as available-for-sale, as the sale of such investments may be required prior to maturity to implement management strategies, and therefore classifies all short-term investments with maturity dates beyond 90 days at the date of purchase as current assets in the accompanying balance sheets. Short-term investments are carried at fair value with the unrealized gains and losses included in other comprehensive income (loss) as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income as an adjustment to yield using the straight-line method over the life of the instrument. A decline in the market value of any short-term investment below amortized cost that is determined to be other-than-temporary will result in a revaluation of its carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. No such impairment charges were recorded for any period presented. Realized gains and losses are determined using the specific identification method and are included in other income (expense). The following tables summarize the short-term investments held at June 30, 2021 and December 31, 2020 (in thousands): June 30, 2021 Amortized Gross Estimated Asset backed securities 38,042 ( 8 ) 38,034 Corporate debt securities 76,341 25 76,366 $ 114,383 $ 17 $ 114,400 December 31, 2020 Amortized Gross Estimated Asset backed securities 3,938 5 3,943 Corporate debt securities 11,276 12 11,288 $ 15,214 $ 17 $ 15,231 The following table summarizes contractual maturities of available-for-sale debt securities held at June 30, 2021 and December 31, 2020 (in thousands): June 30, December 31, Estimated Estimated Due within one year $ 62,981 $ 9,559 After one but within five years $ 51,419 5,672 Total $ 114,400 $ 15,231 The Company determined there was no material change in the credit risk of any of its investments. Property and Equipment, Net Property and equipment, net, which consists primarily of computers, software, lab equipment, furniture and fixtures, and leasehold improvements, are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets (generally three to five years ). Leasehold improvements are amortized over the remaining life of the lease or the useful life, whichever is shorter. Repairs and maintenance costs are charged to expense as incurred. Deferred Offering Costs The Company had deferred offering costs consisting of legal and accounting fees directly attributable to its initial public offering. In June, 2021 the Company completed its initial public offering and offset $ 2.8 million of IPO costs against the proceeds. As of June 30, 2021, $ 1.4 million of deferred IPO costs were included in accounts payable on the Company’s balance sheet. Deferred Rent Rent expense is recognized on a straight-line basis over the initial lease term. The difference between rent expense and amounts paid under the lease agreement is deferred and recorded in short and long-term liabilities in the accompanying balance sheet. Impairment of Long-Lived Assets Long-lived assets consist primarily of property and equipment. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Fair value would be assessed using discounted cash flows or other appropriate measures of fair value. The Company did no t recognize any impairment losses for six months ended June 30, 2021 and June 30, 2020 , respectively. Fair Value Measurements Certain assets and liabilities are carried at fair value under GAAP and consist principally of cash equivalents, restricted cash, accounts payable, accrued liabilities, a warrant to purchase convertible preferred stock and convertible promissory notes. The carrying amounts of cash equivalents, accounts payable, and accrued liabilities approximate their related fair values due to the short-term nature of these instruments. None of the Company’s non-financial assets or liabilities are recorded at fair value on a recurring basis. As permitted under Accounting Standards Codification (“ASC”) 825, Financial Instruments, (“ASC 825”), the Company has elected the fair value option to account for its 2021 Notes and warrant to purchase convertible preferred stock. Changes in fair value of the warrant to purchase convertible preferred stock and the 2021 Notes are recorded in the statements of operations and comprehensive loss. As a result of applying the fair value option, direct costs and fees related to the 2021 Notes were recognized as incurred and not deferred. In June 2021 in connection with the IPO completion, the 2021 Notes converted into the Company's common stock and a warrant to purchase shares of convertible preferred stock was adjusted into a warrant to purchase an equivalent number of shares of the Company's common stock. There are significant judgments and estimates inherent in the determination of the fair value of these liabilities. If the Company had made different assumptions including, among others, those related to the timing and probability of various corporate scenarios, discount rates, volatilities and exit valuations, the carrying values of the warrant liabilities and the 2021 Notes, and net loss and net loss per common share could have been significantly different. Research and Development Expenses The Company’s research and development costs consist primarily of salaries, payroll taxes, employee benefits and stock-based compensation for personnel engaged in research and development activities; fees paid to consultants; license fees paid to third parties for use of their intellectual property, laboratory supplies and development materials; allocated overhead costs; and facilities and depreciation costs. All research and development costs are charged to expense as incurred. Patent Costs Costs related to filing and pursuing patent applications are recorded as general and administrative expenses within the Company’s statements of operations and comprehensive loss and expensed as incurred since recoverability of such expenditures is uncertain . Issuance Costs Related to Equity and Debt The Company allocates issuance costs between the individual freestanding instruments identified on the same basis as proceeds were allocated. Issuance costs associated with the issuance of debt is recorded as a direct reduction of the carrying amount of the debt liability but limited to the notional value of the debt. The Company accounts for the SVB Loan Agreement debt as liabilities measured at amortized cost and amortizes the resulting debt discount to interest expense using the effective interest method over the expected term of the debt. Stock-Based Compensation The Company accounts for stock-based compensation by measuring and recognizing compensation expense for all share-based awards made to employees and non-employees based on estimated grant-date fair values. The Company uses the straight-line method to allocate compensation cost to reporting periods over the requisite service period, which is generally the vesting period. The Company recognizes actual forfeitures by reducing the stock-based compensation in the same period as the forfeitures occur. The Company estimates the fair value of share-based awards to employees and non-employees using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the input of subjective assumptions, including fair value of common stock, expected term, expected volatility, risk-free interest rate, and expected dividend yield, which are described in greater detail below. Estimating the fair value of equity-settled awards as of the grant date using the Black-Scholes option pricing model is affected by assumptions regarding a number of complex variables. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation is recognized. These inputs are subjective and generally require significant analysis and judgment to develop. These inputs are as follows: Fair value of common stock — For grants prior to the Company’s IPO in June 2021, when there was no public market for the Company’s common stock, the Company’s grant date fair market value was determined by the Company’s board of directors based in part on valuations of the Company’s common stock prepared by a third-party valuation specialist. In connection with the preparation of the financial statements for the year ended December 31, 2020, the Company performed a retrospective review of the fair value of its common stock related to the current events available. Based on this review, the Company recorded stock compensation as reflected in the financial statements for that period. For all grants subsequent to the IPO, the fair value of common stock was determined by using the closing price per share of the Company's common stock on the grant date as reported on the Nasdaq Global Select Market. Expected term —The expected term represents the average period that the Company’s options granted are expected to be outstanding and is determined using the simplified method (based on the mid-point between the weighted-average vesting date and the end of the contractual term). The Company has very limited historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior for its stock option grants. Expected volatility — The Company had no publicly available stock price information prior to its IPO and limited publicly available stock price information subsequent to its IPO and therefore the Company has used the historical volatility of the stock price of similar publicly traded peer companies. The historical volatility is calculated based on a period of time commensurate with the expected term assumptions. Risk-free interest rate —The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the options. Expected dividend yield —The Company has never paid dividends on its common stock and have no plans to pay dividends on its common stock. Therefore, the Company used an expected dividend yield of zero. The Company will continue to use judgment in evaluating the expected volatility, expected terms, and interest rates utilized for its stock-based compensation calculations on a prospective basis. Assumptions the Company used in applying the Black-Scholes option pricing model to determine the estimated fair value of its stock options granted involve inherent uncertainties and the application of significant judgment. As a result, if factors or expected outcomes change and the Company uses significantly different assumptions or estimates, its equity-based compensation could be materially different. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized as income or expense in the period that includes the enactment date. The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions on the basis of a two-step process whereby (i) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. Comprehensive Income (Loss) Comprehensive income (loss) is defined as a change in equity during a period from transactions and other events and circumstances from non-owner sources. The only component of other comprehensive income (loss) is unrealized gain (loss) on available-for-sale securities. Comprehensive gains have been reflected in the statements of operations and comprehensive loss, and as a separate component in the statements of stockholders’ equity. Net Loss Per Share In periods of net loss, basic loss per share is computed by dividing net loss available to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for potentially dilutive securities. For periods prior to the IPO, the convertible preferred stock contain non-forfeitable rights to dividends with the common stockholders, and therefore are considered to be participating securities. For purposes of this calculation, outstanding stock options, an outstanding warrant, convertible preferred stock and shares of common stock subject to repurchase by the Company are excluded from the calculation of diluted net loss per common share for the periods presented as their effect would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the anti-dilutive effect of the securities. Recent Accounting Pronouncements—Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). The new standard establishes a right-of-use model and requires a lessee to recognize on the balance sheet a right-of-use asset and corresponding lease liability for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for the Company’s annual periods beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022 and early adoption is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. ASU 2016-13 is effective for the Company’s annual periods beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its financial statements and related disclosures. In November 2018, the FASB issued ASU No. 2018-18 (“ASU 2018-18”), which clarifies the interaction between ASC Topic 808, Collaborative Arrangements , and ASC Topic 606, Revenue from Contracts with Customers . This guidance, among other items, clarifies that certain transactions between collaborative participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. ASU 2018-18 is effective for the Company’s fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of the adoption of this standard on its financial statements and related disclosures. In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), as part of its initiative to reduce complexity in accounting standards. The amendments in the ASU are effective for the Company’s fiscal years beginning after December 15, 2021, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. The Company is currently evaluating the impact of the adoption of this standard on its financial statements and related disclosures. |

Fair Value Measurements | 3. Fair Value Measurements The accounting guidance defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets. Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly. Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. When quoted market prices are available in active markets, the fair value of assets and liabilities is estimated within Level 1 of the valuation hierarchy. If quoted prices are not available, then fair values are estimated by using pricing models, quoted prices of assets and liabilities with similar characteristics, or discounted cash flows, within Level 2 of the valuation hierarchy. In cases where Level 1 or Level 2 inputs are not available, the fair values are estimated by using inputs within Level 3 of the hierarchy. The fair value of short-term investments is based upon market prices quoted on the last day of the fiscal period or other observable market inputs. During 2019 and 2020, the Company issued a warrant in connection with its long-term debt (Note 6). The fair value of these warrants was remeasured at each financial reporting period with any changes in fair value being recognized as a component of other income (expense) in the statements of operations and comprehensive loss. In connection with completion of the initial public offering in June 2021, we performed the final remeasurement of the warrant liability. The value for the warrant liability balance was based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. None of the Company’s assets or liabilities are recorded at fair value on a recurring basis, except for short-term investments and 2021 Notes and the warrant prior to the conversion. No transfers between levels have occurred during the periods presented. The following tables summarize the Company’s assets and liabilities measured at fair value on a recurring basis as of June 30, 2021 and December 31, 2020 and (in thousands): June 30, 2021 Assets: Level 1 Level 2 Level 3 Total Money market funds (cash equivalents) $ 4,036 $ - $ - $ 4,036 Asset backed securities 38,042 - 38,042 Corporate debt securities $ - $ 72,304 $ - $ 72,304 Total Assets $ 4,036 $ 110,346 $ - $ 114,382 December 31, 2020 Assets: Level 1 Level 2 Level 3 Total Money market funds (cash equivalents) $ 5,426 $ - $ - $ 5,426 Asset backed securities - 3,943 - 3,943 Corporate debt securities - 11,288 - 11,288 Total assets $ 5,426 $ 15,231 $ - $ 20,657 Liability: Warrant liability $ - $ - $ 451 451 Total liabilities $ - $ - $ 451 $ 451 The following table provides reconciliation for all liabilities measured at fair value using significant unobservable inputs (Level 3) for the six months ended June 30, 2021 (in thousands): Balance at December 31, 2020 $ 451 Change in fair value of warrant through conversion $ 2,180 Reclassification of warrant liability into equity $ ( 2,631 ) Balance at June 30, 2021 $ - Balance at December 31, 2020 $ - Fair value of convertible promissory notes at issuance $ 130,500 Change in fair value of convertible promissory notes through conversion $ 35,199 Conversion of convertible promissory notes $ ( 165,699 ) Balance at June 30, 2021 $ - In March 2020 in connection with the second draw of the Company’s debt agreement the warrant was amended to increase the number of shares by 96,867 . The change in fair value of the warrant for the six months ended June 30, 2021 and June 30, 2020 was $ 2.2 million and $ 0 million , respectively. In connection with the completion of the Company’s IPO in June 2021, in accordance with the original terms the warrant instrument, the Company adjusted the SVB warrant into a warrant to purchase common stock of the Company (Note 10). Below are the assumptions used for the Black-Scholes option pricing valuation model for the fair value of the warrant liability as of the conversion date and December 31, 2020: December 31, Assumption At conversion date 2020 Fair Value 22.00 4.59 Expected volatility 62.00 % 60.00 % Expected term (years) 8.47 8.99 Expected dividend yield 0.00 % 0.00 % Risk-free interest rate 1.62 % 0.93 % The fair value on the date of measurement of the Series B convertible preferred stock, the underlying instrument, was estimated by management with the assistance of a third-party valuation specialist. The expected volatility is based on historical volatilities from guideline companies, since there is no active market for the Company’s common stock. The Company based the expected term assumption on the actual remaining contractual term of the warrant as of the date of measurement. The Company has not paid, and does not expect to pay, any cash dividends in the foreseeable future. The risk-free interest rate used is the rate for a U.S. Treasury zero coupon issue with a term consistent with the remaining contractual term of the warrant on the date of measurement. In February 2021, the Company sold and issued approximately $ 130.5 million aggregate principal amount of 2021 Notes in a private placement transaction. The 2021 Notes accrued 6 % interest per annum. The Company elected to account for the 2021 Notes at fair value, as of the issuance date. Management believes that the fair value option better reflects the underlying economics of the 2021 Notes, which contain multiple embedded derivatives. Under the fair value election, changes in fair value are reported as “Change in fair value of convertible promissory notes” in the statements of operations in each reporting period subsequent to the issuance through the conversion of the 2021 Notes. The Company measured the fair value of the 2021 Notes using the probability weighted “as converted” plus Black-Scholes model based on the inputs such as probability of IPO scenario vs. Non-IPO scenario, fair value of common stock price, discount yield, risk free rate, equity volatility, years expected term, number of converted shares and price negotiation adjustment for the calibration. In June, in connection with the completion of the Company's IPO, the 2021 Notes converted into 7,531,777 shares of the Company's common stock. Based on the terms of the agreement, the 2021 Notes converted at a 20 % discount from the actual offering price. Prior to the conversion, the Company recorded a final fair value adjustment of the 2021 Notes using the Company's common stock price at the IPO. There are significant judgments, assumptions and estimates inherent in the determination of the fair value of each of the instruments described above. These include determination of a valuation method and selection of the possible outcomes available to the Company, including the determination of timing and expected future investment returns for such scenarios. The Company considered the equity value of an initial public offering using market transactions and have determined the expected value of a stay private scenario using the income approach, which is based on assumptions regarding the Company’s future operating performance. The related judgments, assumptions and estimates are highly interrelated and changes in any one assumption could necessitate changes in another. In particular, any changes in the probability of a particular outcome would require a related change to the probability of another outcome. In addition, the fair value of the 2021 Notes is derived using assumptions that are consistent with the assumptions used to value the Company’s common stock and the Warrant. As of June 30, 2021 , the derivative liabilities no longer exist as a result of the automatic conversion of the convertible preferred stock upon the Company's IPO and the warrant liabilities have been reclassified into equity after the warrant became exercisable for common stock in connection with the Company’s IPO. |

Debt Disclosure [Abstract] | |
Long-term Debt | 6. Long-Term Debt In November 2019, the Company entered into a loan and security agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”) pursuant to which SVB agreed to lend to the Company up to $ 15.0 million in a series of term loans (the “Loan”). Contemporaneously, the Company borrowed $ 2.5 million in the first of three draw-downs available through September 30, 2021. The additional draws are at the discretion of the Company, but the Company is subject to penalties and fees if not fully drawn down. Simultaneously with the first draw-down, SVB entered into a warrant agreement with the Company to purchase 32,289 shares of Series B convertible preferred stock of the Company at an exercise price of $ 2.3228 per share (as amended, the “SVB warrant”). The SVB warrant will be adjusted to increase the number of shares of the Company’s Series B convertible preferred stock underlying the SVB warrant if the Company elects to draw down additional funds under the Loan (Note 10). In March 2020, the Company borrowed an additional $ 7.5 million as a second draw down related to the Loan and the SVB warrant was amended to increase the number of shares of Series B convertible preferred stock of the Company by 96,867 . In connection with the completion of the Company’s IPO in June 2021, in accordance with the original terms the warrant instrument, the Company adjusted the SVB warrant into a warrant to purchase common stock of the Company. As of June 30, 2021 , the warrants were net exercised into 117,088 shares of common stock of the Company. The outstanding balance of the Loan is due on the scheduled maturity date of September 1, 2023 (the “Maturity Date”). Payment on the Loan will be interest only through September 30, 2021, followed by 24 equal monthly payments of principal plus accrued interest commencing on October 1, 2021. The per annum interest rate for any outstanding Loan balance is the greater of (i) 0.65 % above the Prime Rate or (ii) 5.90%. The interest rate as of June 30, 2021 and December 31, 2020 was 5.90 %. In addition, a final payment (“Final Payment”) equal to the original principal amount of each advance multiplied by 5.50 % will be due on the Maturity Date. The Company may prepay the borrowed amounts, provided that the Company will be obligated to pay a prepayment fee equal to (i) 3 % of the outstanding principal balance of all draw-downs if the draw-downs are repaid prior to the first anniversary of the draw-down date, (ii) 2 % of the outstanding principal balance of all draw-downs if the draw-downs are repaid on or after the first anniversary of the draw-down date but prior to the second anniversary of the draw-down date, and (iii) 1 % of the outstanding principal balance of all draw-downs if the draw-downs are repaid on or after the second anniversary of the draw-down date but before the Maturity Date. Further, the Company is subject to a 1 % unused line fee payable to SVB related to the undrawn portion of the borrowing capacity on September 30, 2021 or, if applicable, upon prepayment. As of June 30, 2021 and December 31, 2020 , the debt issuance costs related to the Loan were $ 0.5 million and $ 0.6 million, respectively, the fair value of the warrant at issuance date is included within this balance (Note 10). The debt issuance costs and Final Payment are amortized to interest expense over the term of the loan using the effective interest method. The long-term debt and unamortized discount balances as of June 30, 2021 and December 31, 2020 are shown below (in thousands): June 30, December 31, 2021 2020 Total long-term debt $ 10,000 $ 10,000 Less unamortized discount ( 445 ) ( 605 ) Total long-term debt, net 9,555 9,395 Less current portion of long-term debt ( 3,473 ) ( 926 ) Long-term debt, net of current portion $ 6,082 $ 8,469 The Company is subject to customary affirmative and restrictive covenants under the SVB Loan agreement. The Company’s obligations under the SVB Loan agreement are secured by a first priority security interest in substantially all of the Company’s current and future assets, other than intellectual property. The Company has agreed not to encumber its intellectual property assets, except as permitted by the SVB Loan agreement. The Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, the failure to fulfill certain obligations under the Loan Agreement and the occurrence of a material adverse change in the business, operations, or condition (financial or otherwise), a material impairment of the prospect of repayment of any portion of the Loan, or a material impairment in the perfection or priority of SVB’s lien in the collateral or in the value of such collateral. In the event of default by the Company under the Loan Agreement, SVB would be entitled to exercise their remedies thereunder, including the right to accelerate the debt, upon which the Company may be required to repay all amounts then outstanding under the Loan Agreement. As of June 30, 2021 and December 31, 2020, the Company was in compliance with all covenants under the Loan Agreement and there had been no material adverse change in its business. Future minimum payments of outstanding principal and interest under the outstanding draw-down of $ 10.0 million on the Loan consist of the following: As of June 30, 2021 2021 (six months remaining) 1,544 2022 5,386 2023 4,393 Total future minimum payments 11,323 Less: Interest payments ( 1,323 ) Long-term debt 10,000 In February 2021, the Company issued the 2021 Notes to various investors, in the aggregate principal amount of $ 130.5 million. The 2021 Notes accrued interest at 6 % per annum. Due to certain embedded features within the 2021 Notes, the Company elected to account for these notes and all their embedded features under the fair value option. For the six months ended June 30, 2021 , the Company recognized $ 35.2 million of change in fair value of convertible promissory notes in the statements of operations and comprehensive loss related to increases in the fair value of the 2021 Notes. In June 2021, in connection with the completion of the Company’s IPO, the Notes were converted into 7,531,777 shares of the Company’s common stock. |

Commitments and Contingencies | 7. Commitments and Contingencies Columbia License Agreement and Sponsored Research Agreement In 2016, the Company entered into an exclusive license agreement (the “License Agreement”) with The Trustees of Columbia University (“Columbia”). Under the License Agreement, the Company acquired the exclusive right to use certain patents, materials and information. The License Agreement includes a number of diligence obligations that require the Company to use commercially reasonable efforts to research, discover, develop and market products covered by the patents, materials and information licensed by Columbia by certain dates. The License Agreement provides for the potential payment to Columbia of development milestones and royalties on net sales of products covered by the licensed patents, materials or information. The license fee was immaterial for all periods presented. The Company does not believe that its G4 or PX Instruments or the associated consumables, as the Company presently intends to commercialize them, fit within the definitions in the License Agreement that would require the Company to make milestone payments or pay royalties on sales of these products and as a result no amounts have been accrued to date. However, there is no assurance that Columbia will agree with the Company’s interpretation of the License Agreement or its payment obligations thereunder or agree that the Company has complied with its other obligations under the License Agreement. In addition to the License Agreement, the Company entered into a sponsored research agreement (the “Research Agreement”) to fund a research program with Columbia. The program ended in 2019. The Company recorded $ 0.1 million of expense in connection with the Research Agreement for the year ended December 2019. Operating Lease In November 2017, the Company entered into a non-cancelable operating lease that expires upon commencement of the new HQ lease, as defined below (estimated second quarter of 2022). The lease includes certain rent escalations and additional charges for common area maintenance and other costs. The Company gained access to the leased space and began recognizing rent expense under this lease in February 2018. In December 2019, the Company entered into a 5-year lease agreement for an additional office space in San Diego, California. The lease includes certain rent escalations and additional charges for common area maintenance and other costs. The Company gained access to the leased space and began recognizing rent expense under this lease in January 2020. In June 2020, the Company entered into a sublease agreement for an additional office space in La Jolla, California. The sublease includes certain rent escalations and additional charges for common area maintenance and other costs. The Company gained access to the leased space and began recognizing rent expense under this sublease in July 2020. In June 2020, the Company entered into a 10-year lease agreement with ARE-SD Region No. 27, LLC (“landlord”) for new office and laboratory space containing approximately 76,778 rentable square feet located in La Jolla, California (“premises”, “new HQ lease”), with a target commencement date in April 2022. If landlord does not deliver the premises within 120 days of the target commencement date for any reason other than Force Majeure delays or delays by the Company, the Company may terminate by the Company and neither landlord nor the Company will have any further rights, duties, or obligations under the new HQ lease. Landlord shall make available to the Company for use within 12-months after the commencement date a Tenant Improvement Allowance (“TI Allowance”), which the Company will repay to the landlord as additional rent over the base term and shall accrue interest at a rate of 8 % per annum. Upon commencement, the contractual base rent will be charged, subject to partial rent abatement, annual base rent adjustments, the Company’s share of operating expenses, and additional rent for the TI Allowance actually disbursed by the landlord. In April 2021, the Company entered into a 62-month lease agreement for an additional office space in San Diego, California. The lease includes certain rent escalations and additional charges for common area maintenance and other costs. The Company gained access to the leased space in June 2021 and began recognizing rent expense under this lease at that time. In April 2021, the Company amended its current lease for an office space in La Jolla, California. The lease amendment includes extension of the current lease expiration date by 24-months subsequent to commencement of new HQ lease, expansion of the existing premises for additional space and certain rent escalations. The Company recorded rent expense of $ 0.8 million and $ 0.3 million for the six months ended June 30, 2021 and June 30, 2020, respectively. Future minimum payments under the Company’s non-cancelable operating leases are as follows (in thousands): As of June 30, 2021 Operating 2021 (six months remaining) 1,166 2022 6,265 2023 7,892 2024 6,394 2025 and thereafter 42,122 $ 63,839 |

Convertible Preferred Stock | 8. Convertible Preferred Stock Prior to its conversion to common stock in connection with the Company’s IPO, the convertible preferred stock was classified as temporary, or mezzanine, equity on the accompanying condensed balance sheets since the shares contained certain redemption features that were not solely within the control of the Company.

Common Stock Warrant | 10. Common Stock Warrant As discussed in Note 6, the Company issued a warrant to SVB concurrently with the Loan Agreement, which warrant was later amended. Upon the closing of the Company’s IPO in June 2021, warrants to purchase shares of Series B Preferred Stock automatically converted into warrants to purchase shares of our Common Stock. The preferred stock warrant liability was reclassified from current liabilities to equity, as the warrants met the definition of an equity instrument. As a result, the fair value of the preferred stock warrants as of June 1, 2021, estimated to be $ 2.6 million using the Black-Scholes option-pricing model, was reclassified to additional paid-in capital. At that time the warrant became exercisable for 129,156 shares of common stock of the Company at $ 2.3228 per share. As of June 30, 2021 the warrant has been net exercised into 117,088 shares of common stock of the Company. |

Stock Incentive Plan | 11. Stock Incentive Plan 2021 and 2016 Equity Incentive Plans The Company's Board of Directors and stockholders adopted and approved the Company's 2021 Equity Incentive Plan (the “2021 Plan”) in May 2021. The 2021 Plan replaced the Company's 2016 Equity Incentive Plan adopted in September 2016 (the “2016 Plan”), however, awards outstanding under the 2016 Plan will continue to be governed by their existing terms. The number of shares of the Company's common stock that were initially available for issuance under the 2021 Plan equaled the initial sum of 7,500,000 shares plus 832,980 shares that were then available for issuance under the 2016 Plan. The 2021 Plan provides for the following types of awards: incentive and non-statutory stock options, stock appreciation rights, restricted shares, and restricted stock units. The number of shares of common stock reserved for issuance under the 2021 Plan are increased automatically on the first business day of each fiscal year, commencing in 2022 and ending in 2031, by a number equal to the lesser of : (i) 5% of the shares of common sto ck outstanding on the last business day of the prior fiscal year; or (ii) the number of shares determined by the Company's Board of Directors. In general, to the extent that any awards under the 2021 Plan are forfeited, terminate, expire or lapse without the issuance of shares, or if the Company reacquires the shares subject to awards granted under the 2021 Plan, those shares will again become available for issuance under the 2021 Plan, as will shares applied to pay the exercise or purchase price of an award or to satisfy tax withholding obligations related to any award. Stock-based awards are governed by agreements between the Company and the recipients. Incentive stock options and nonqualified stock options may be granted under the 2021 Plan (and previously the 2016 Plan) at an exercise price of not less than 100 % of the fair market value of common stock on the respective date of grant. The grant date is the date the terms of the award are formally approved by the Company’s Board of Directors or its designee. The following table summarizes stock option activity under the Plan since December 31, 2020: Number of Options Weighted Weighted Outstanding at December 31, 2020 7,274,953 $ 0.57 8.81 Exercisable at December 31, 2020 7,274,953 $ 0.57 8.81 Granted 2,855,700 $ 8.62 Exercised ( 5,381,217 ) $ 0.65 Canceled / Forfeited ( 70,398 ) $ 3.43 Outstanding at June 30, 2021 4,679,038 $ 5.35 8.88 Exercisable at June 30, 2021 3,335,363 $ 2.41 8.52 The 2016 Plan allows for the early exercise of awards to plan participants subject to the right of repurchase by the Company at the lower of the original exercise price or fair market value for unvested awards. At June 30, 2021 and December 31, 2020 , the Company has a liability for the cash received from the early exercise of stock options in the amount of $ 2.2 million and $ 0 million, respectively. The Company reduces the liability as the underlying shares vest in accordance with the vesting terms of the individual award. As of June 30, 2021 and December 31, 2020 , there were 2,958,410 and 141,955 respectively, of early exercised stock options that remain subject to the Company’s repurchase right. ESPP Shares In May 2021, the Company’s Board of Directors approved the 2021 Employee Stock Purchase Plan (the “ESPP”). A total of 730,000 shares of common stock was initially reserved for issuance under the ESPP. The price at which common stock is purchased under the ESPP is equal to 85 % of the fair market value of the common stock on the first day of the offering period or purchase date, whichever is lower. During the six months ended June 30, 2021, no shares of common stock were issued under the ESPP.

Accounting Policies [Abstract] | |
Initial Public Offering | Initial Public Offering On June 1, 2021, the Company completed its initial public offering ("IPO") in which it sold 11,730,000 shares of common stock (which included 1,530,000 shares that were sold pursuant to the full exercise of the IPO underwriters’ option to purchase additional shares) at a public offering price of $ 22.00 per share. The Company received net proceeds of approximately $ 237.2 million after deducting offering costs, underwriting discounts, and commissions of $ 20.9 million. Concurrent with the completion of the IPO: 38,826,388 outstanding shares of convertible preferred stock converted into an equivalent number of shares of common stock; outstanding principal and interest amount of convertible promissory notes (the "2021 Notes") converted into 7,531,777 shares of the Company's common stock; a warrant to purchase 129,156 shares of convertible preferred stock was adjusted into a warrant to purchase an equivalent number of shares of the Company's common stock. |
Liquidity and Capital Resources | Liquidity and Capital Resources The Company has experienced net losses since inception and, as of June 30, 2021 and December 31, 2020, had an accumulated deficit of $ 114.5 million and $ 53.1 million , respectively. The Company has a limited operating history and the revenue and income potential of the Company’s business are unproven. From incorporation in June 2016 through June 30, 2021, substantially all of the Company’s operations have been funded by the sales of equity securities and issuances of debt. As of June 30, 2021, the Company had cash and cash equivalents and short-term investments totaling, in aggregate, $ 371.7 million . Management expects to continue to incur significant expenses for the foreseeable future and to incur operating losses in the near term while the Company makes investments to support its anticipated growth. The Company cannot be certain that it will ever be profitable or generate positive cash flow from operating activities or that, if it achieves profitability, it will be able to sustain it. The Company believes that its cash and cash equivalents balance as of June 30, 2021 provides sufficient capital resources to continue its operations for at least 12 months from the issuance date of the accompanying unaudited condensed financial statements. |
Basis of Presentation and Use of Estimates | Basis of Presentation and Use of Estimates The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures required by GAAP for annual financial statements have been omitted. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Interim financial results are not necessarily indicative of results anticipated for the full year. The preparation of the Company’s unaudited condensed financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities in the Company’s unaudited condensed financial statements and accompanying notes. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may significantly differ from these estimates and assumptions. Significant estimates and assumptions include the useful lives of property and equipment, the fair value of warrant liabilities, the fair value of the Company’s preferred and common stock and stock-based compensation and the fair value of the 2021 Notes. |
Impact of the COVID -19 Pandemic | Impact of the COVID-19 Pandemic The Company is continuing to assess the impact of the COVID-19 pandemic on its current and future business and operations, as well as on the Company’s industry and the healthcare system. Any of the foregoing could harm the Company’s operations and the Company cannot anticipate all the ways in which it could be adversely impacted by health epidemics such as COVID-19. |
Segment Information | Segment Information Operating 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 singular focus is the development and eventual commercialization of proprietary sequencing solutions. The Company views its operations and manages its business in one operating and reporting segment. The Company’s long-lived assets are located in the United States. |
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include cash readily available in checking, savings, money market and sweep accounts. The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. |
Restricted Cash | Restricted Cash Restricted cash is held in a separate restricted bank account as the collateral for the security deposits on three executed lease agreements and the collateral on the Company’s corporate credit card program. The Company has classified these deposits as long-term restricted cash on its balance sheets. The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the balance sheets that sum to the total of the same such amounts shown in the statements of the cash flows as of June 30, 2021 and December 31, 2020 (in thousands): June 30, December 31, Cash and cash equivalents $ 257,268 $ 11,688 Restricted cash 687 482 Total $ 257,955 $ 12,170 |
Concentration of Credit Risk | Concentration of Credit Risk Financial instruments, which potentially subject the Company to a concentration of credit risk, consist primarily of cash, cash equivalents and short-term investments. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and management believes that the Company is not exposed to significant credit risk due to the financial position of the depository institutions in which those deposits are held. |
Short-Term Investments | Short-Term Investments As of June 30, 2021 and December 31, 2020 , short-term investments primarily consisted of corporate debt securities, and asset backed securities. The Company classifies all short-term investments as available-for-sale, as the sale of such investments may be required prior to maturity to implement management strategies, and therefore classifies all short-term investments with maturity dates beyond 90 days at the date of purchase as current assets in the accompanying balance sheets. Short-term investments are carried at fair value with the unrealized gains and losses included in other comprehensive income (loss) as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income as an adjustment to yield using the straight-line method over the life of the instrument. A decline in the market value of any short-term investment below amortized cost that is determined to be other-than-temporary will result in a revaluation of its carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. No such impairment charges were recorded for any period presented. Realized gains and losses are determined using the specific identification method and are included in other income (expense). The following tables summarize the short-term investments held at June 30, 2021 and December 31, 2020 (in thousands): June 30, 2021 Amortized Gross Estimated Asset backed securities 38,042 ( 8 ) 38,034 Corporate debt securities 76,341 25 76,366 $ 114,383 $ 17 $ 114,400 December 31, 2020 Amortized Gross Estimated Asset backed securities 3,938 5 3,943 Corporate debt securities 11,276 12 11,288 $ 15,214 $ 17 $ 15,231 The following table summarizes contractual maturities of available-for-sale debt securities held at June 30, 2021 and December 31, 2020 (in thousands): June 30, December 31, Estimated Estimated Due within one year $ 62,981 $ 9,559 After one but within five years $ 51,419 5,672 Total $ 114,400 $ 15,231 The Company determined there was no material change in the credit risk of any of its investments. |
Property and Equipment, Net | Property and Equipment, Net Property and equipment, net, which consists primarily of computers, software, lab equipment, furniture and fixtures, and leasehold improvements, are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets (generally three to five years ). Leasehold improvements are amortized over the remaining life of the lease or the useful life, whichever is shorter. Repairs and maintenance costs are charged to expense as incurred. |
Deferred Offering Costs | Deferred Offering Costs The Company had deferred offering costs consisting of legal and accounting fees directly attributable to its initial public offering. In June, 2021 the Company completed its initial public offering and offset $ 2.8 million of IPO costs against the proceeds. As of June 30, 2021, $ 1.4 million of deferred IPO costs were included in accounts payable on the Company’s balance sheet. |
Deferred Rent | Deferred Rent Rent expense is recognized on a straight-line basis over the initial lease term. The difference between rent expense and amounts paid under the lease agreement is deferred and recorded in short and long-term liabilities in the accompanying balance sheet. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets Long-lived assets consist primarily of property and equipment. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. Fair value would be assessed using discounted cash flows or other appropriate measures of fair value. The Company did no t recognize any impairment losses for six months ended June 30, 2021 and June 30, 2020 , respectively. |
Fair Value Measurements | Fair Value Measurements Certain assets and liabilities are carried at fair value under GAAP and consist principally of cash equivalents, restricted cash, accounts payable, accrued liabilities, a warrant to purchase convertible preferred stock and convertible promissory notes. The carrying amounts of cash equivalents, accounts payable, and accrued liabilities approximate their related fair values due to the short-term nature of these instruments. None of the Company’s non-financial assets or liabilities are recorded at fair value on a recurring basis. As permitted under Accounting Standards Codification (“ASC”) 825, Financial Instruments, (“ASC 825”), the Company has elected the fair value option to account for its 2021 Notes and warrant to purchase convertible preferred stock. Changes in fair value of the warrant to purchase convertible preferred stock and the 2021 Notes are recorded in the statements of operations and comprehensive loss. As a result of applying the fair value option, direct costs and fees related to the 2021 Notes were recognized as incurred and not deferred. In June 2021 in connection with the IPO completion, the 2021 Notes converted into the Company's common stock and a warrant to purchase shares of convertible preferred stock was adjusted into a warrant to purchase an equivalent number of shares of the Company's common stock. There are significant judgments and estimates inherent in the determination of the fair value of these liabilities. If the Company had made different assumptions including, among others, those related to the timing and probability of various corporate scenarios, discount rates, volatilities and exit valuations, the carrying values of the warrant liabilities and the 2021 Notes, and net loss and net loss per common share could have been significantly different. |
Research and Development Expenses | Research and Development Expenses The Company’s research and development costs consist primarily of salaries, payroll taxes, employee benefits and stock-based compensation for personnel engaged in research and development activities; fees paid to consultants; license fees paid to third parties for use of their intellectual property, laboratory supplies and development materials; allocated overhead costs; and facilities and depreciation costs. All research and development costs are charged to expense as incurred. |
Patent Costs | Patent Costs Costs related to filing and pursuing patent applications are recorded as general and administrative expenses within the Company’s statements of operations and comprehensive loss and expensed as incurred since recoverability of such expenditures is uncertain |
Issuance Costs Related to Equity and Debt | Issuance Costs Related to Equity and Debt The Company allocates issuance costs between the individual freestanding instruments identified on the same basis as proceeds were allocated. Issuance costs associated with the issuance of debt is recorded as a direct reduction of the carrying amount of the debt liability but limited to the notional value of the debt. The Company accounts for the SVB Loan Agreement debt as liabilities measured at amortized cost and amortizes the resulting debt discount to interest expense using the effective interest method over the expected term of the debt. |
Stock-Based Compensation | Stock-Based Compensation The Company accounts for stock-based compensation by measuring and recognizing compensation expense for all share-based awards made to employees and non-employees based on estimated grant-date fair values. The Company uses the straight-line method to allocate compensation cost to reporting periods over the requisite service period, which is generally the vesting period. The Company recognizes actual forfeitures by reducing the stock-based compensation in the same period as the forfeitures occur. The Company estimates the fair value of share-based awards to employees and non-employees using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the input of subjective assumptions, including fair value of common stock, expected term, expected volatility, risk-free interest rate, and expected dividend yield, which are described in greater detail below. Estimating the fair value of equity-settled awards as of the grant date using the Black-Scholes option pricing model is affected by assumptions regarding a number of complex variables. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation is recognized. These inputs are subjective and generally require significant analysis and judgment to develop. These inputs are as follows: Fair value of common stock — For grants prior to the Company’s IPO in June 2021, when there was no public market for the Company’s common stock, the Company’s grant date fair market value was determined by the Company’s board of directors based in part on valuations of the Company’s common stock prepared by a third-party valuation specialist. In connection with the preparation of the financial statements for the year ended December 31, 2020, the Company performed a retrospective review of the fair value of its common stock related to the current events available. Based on this review, the Company recorded stock compensation as reflected in the financial statements for that period. For all grants subsequent to the IPO, the fair value of common stock was determined by using the closing price per share of the Company's common stock on the grant date as reported on the Nasdaq Global Select Market. Expected term —The expected term represents the average period that the Company’s options granted are expected to be outstanding and is determined using the simplified method (based on the mid-point between the weighted-average vesting date and the end of the contractual term). The Company has very limited historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior for its stock option grants. Expected volatility — The Company had no publicly available stock price information prior to its IPO and limited publicly available stock price information subsequent to its IPO and therefore the Company has used the historical volatility of the stock price of similar publicly traded peer companies. The historical volatility is calculated based on a period of time commensurate with the expected term assumptions. Risk-free interest rate —The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the options. Expected dividend yield —The Company has never paid dividends on its common stock and have no plans to pay dividends on its common stock. Therefore, the Company used an expected dividend yield of zero. The Company will continue to use judgment in evaluating the expected volatility, expected terms, and interest rates utilized for its stock-based compensation calculations on a prospective basis. Assumptions the Company used in applying the Black-Scholes option pricing model to determine the estimated fair value of its stock options granted involve inherent uncertainties and the application of significant judgment. As a result, if factors or expected outcomes change and the Company uses significantly different assumptions or estimates, its equity-based compensation could be materially different. |
Income Taxes | Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized as income or expense in the period that includes the enactment date. The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company records uncertain tax positions on the basis of a two-step process whereby (i) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. |
Comprehensive Income (Loss) | Comprehensive Income (Loss) Comprehensive income (loss) is defined as a change in equity during a period from transactions and other events and circumstances from non-owner sources. The only component of other comprehensive income (loss) is unrealized gain (loss) on available-for-sale securities. Comprehensive gains have been reflected in the statements of operations and comprehensive loss, and as a separate component in the statements of stockholders’ equity. |
Net Loss Per Share | Net Loss Per Share In periods of net loss, basic loss per share is computed by dividing net loss available to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for potentially dilutive securities. For periods prior to the IPO, the convertible preferred stock contain non-forfeitable rights to dividends with the common stockholders, and therefore are considered to be participating securities. For purposes of this calculation, outstanding stock options, an outstanding warrant, convertible preferred stock and shares of common stock subject to repurchase by the Company are excluded from the calculation of diluted net loss per common share for the periods presented as their effect would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the anti-dilutive effect of the securities. |
Recent Accounting Pronouncements - Not Yet Adopted | Recent Accounting Pronouncements—Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). The new standard establishes a right-of-use model and requires a lessee to recognize on the balance sheet a right-of-use asset and corresponding lease liability for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for the Company’s annual periods beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022 and early adoption is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. ASU 2016-13 is effective for the Company’s annual periods beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its financial statements and related disclosures. In November 2018, the FASB issued ASU No. 2018-18 (“ASU 2018-18”), which clarifies the interaction between ASC Topic 808, Collaborative Arrangements , and ASC Topic 606, Revenue from Contracts with Customers . This guidance, among other items, clarifies that certain transactions between collaborative participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. ASU 2018-18 is effective for the Company’s fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of the adoption of this standard on its financial statements and related disclosures. In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”), as part of its initiative to reduce complexity in accounting standards. The amendments in the ASU are effective for the Company’s fiscal years beginning after December 15, 2021, including interim periods therein. Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. The Company is currently evaluating the impact of the adoption of this standard on its financial statements and related disclosures. |
