Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	The Company Twist Bioscience Corporation (the Company) was incorporated in the state of Delaware on February 4, 2013. The Company is a synthetic biology company that has developed a disruptive DNA synthesis platform. DNA is used in many applications across different industries: industrial chemicals/materials, academic, healthcare and food/agriculture. The Company’s fiscal year ends on September 30. The Company has generated net losses in all periods since its inception. As of March 31, 2023, the Company had an accumulated deficit of $929.4 million and has not generated positive cash flows from operations since inception. Losses are expected to continue as the Company continues to invest in product development, manufacturing, and sales and marketing. Since its inception, the Company has received an aggregate of $1,333.7 million in net proceeds from the issuance of equity securities in its public offerings and an aggregate of $13.8 million from debt. Management believes that these proceeds combined with existing cash balances on hand will be sufficient to fund operations for at least one year from the issuance of these consolidated financial statements. However, if the Company needs to obtain additional financing to fund operations beyond this period, there can be no assurance that it will be successful in raising additional financing on terms which are acceptable to the Company. If the Company requires but is unable to obtain additional funding, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations. During the three and six months ended March 31, 2023, overall financial results of the Company were not significantly affected by the COVID-19 pandemic, which continues to have global impact. The Company has considered all information available as of the date of issuance of these financial statements and the Company is not aware of any specific events or circumstances that would require an update to its estimates or judgments, or a revision to the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. The extent to which the COVID-19 outbreak affects the Company’s future financial results and operations will depend on future developments which continue to evolve and are difficult to predict, including mutations in the SARS-CoV-2 virus, which have resulted and may in the future result in strains that are more contagious and less responsive to current treatment methods, and current or future domestic and international actions to contain it and treat it.

Accounting Policies [Abstract]
Summary of significant accounting policies	Summary of significant accounting policies Basis of presentation and use of estimates The accompanying unaudited condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2022 (the Annual Report on Form 10-K) filed with the Securities and Exchange Commission on November 28, 2022. The condensed consolidated financial statements are unaudited and have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and include, in the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair statement of the condensed consolidated financial statements. The condensed consolidated balance sheet at September 30, 2022 is derived from audited consolidated financial statements but does not include all disclosures required by GAAP. The operating results for the three and six months ended March 31, 2023 are not necessarily indicative of the results expected for the full year ending September 30, 2023 or any interim period. The presentation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Certain prior year amounts have been reclassified to conform to the current year presentation. The Company’s unaudited condensed consolidated financial statements include its wholly owned subsidiaries. All intercompany balances and accounts are eliminated in consolidation. The following table provides a reconciliation of the Company’s cash and cash equivalents and non-current portion of restricted cash reported within the unaudited condensed consolidated balance sheets that sum to the total cash, cash equivalents and restricted cash shown in the Company’s condensed consolidated statements of cash flows: (in thousands) March 31, September 30, Cash and cash equivalents $ 315,196 $ 378,687 Restricted cash, non-current 2,365 1,572 Total cash, cash equivalents and restricted cash $ 317,561 $ 380,259 Restricted cash represents cash held at financial institutions that are pledged as collateral for stand-by letters of credit for lease commitments. Significant accounting policies There have been no material changes in the accounting policies from those disclosed in the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K. Revenue The Company had contract assets of $3.9 million and contract liabilities of $1.9 million as of March 31, 2023. The Company had contract assets of $3.4 million and contract liabilities of $3.5 million as of September 30, 2022. For the three and six months ended March 31, 2023, the Company recognized revenue of $1.4 million and $2.7 million, respectively, from the amount that was included in the contract liability balance at the beginning of each period. For the three and six months ended March 31, 2022, the Company's revenue from the amount that was included in the contract liability balance at the beginning of each period was not material. In addition, for all periods presented, there was no revenue recognized in a reporting period from performance obligations satisfied in previous periods. The aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied as of March 31, 2023 was $7.7 million. The Company expects to recognize revenue over the next twelve months relating to performance obligations unsatisfied as of March 31, 2023. Based on the nature of our contracts with customers, which are recognized over a term of less than 12 months, we have elected to use the practical expedient whereby costs to obtain a contract are expensed as they are incurred. We state our revenues net of any taxes collected from customers that are required to be remitted to various government agencies. The amount of taxes collected from customers and payable to governmental entities is included on the balance sheet as part of “Accrued expenses and other current liabilities.” Recent accounting pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). The Company considered the applicability and impact of all recent ASUs. ASUs not listed below were assessed and determined to be not applicable to the Company’s consolidated financial position and results of operations. Recent accounting pronouncements adopted In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. The amendments in this update require the annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model. The Company adopted this standard effective October 1, 2022. The adoption of ASU-2021-10 did not have an impact on the Company’s condensed consolidated financial statements as of and for the period ended March 31, 2023. Recently issued accounting pronouncement not yet adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard requires entities to use the new “expected credit loss” impairment model for most financial assets measured at amortized cost, including trade and other receivables and held-to-maturity debt securities, and modifies the impairment model for available-for-sale debt securities. The standard is effective for the Company for the

Fair value measurement

Fair value measurement	6 Months Ended

Fair Value Disclosures [Abstract]
Fair value measurement	Fair value measurement The Company assesses the fair value of financial instruments based on the provisions of ASC 820, Fair Value Measurements . ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company's short-term investments primarily utilize broker quotes in a non-active market for valuation of its investments. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value.

The unrealized loss on short-term investments have been in a continuous unrealized loss position for less than 12 months. We believe that the decline in value of these investments is temporary and is primarily related to the change in market interest rates since purchase. We believe it is more likely than not that we will be able to hold these investments to maturity. As of March 31, 2023, there were no financial assets or financial liabilities categorized as level 3 within the fair value hierarchy. As of September 30, 2022, the Company’s contingent consideration related to its Abveris acquisition was categorized as Level 3 within the fair value hierarchy. Contingent consideration was classified as a liability and remeasured to an estimated fair value at each reporting date until the contingency was resolved. Contingent consideration was recorded at its fair values using unobservable inputs and have included using the Monte Carlo simulation option pricing framework, incorporating contractual terms and assumptions regarding financial forecasts, discount rates, and volatility of forecasted revenue. The key assumptions were forecasted calendar year 2022 revenue and the Company's share price. The development and determination of the unobservable inputs for Level 3 fair value measurements and fair value calculations are the responsibility of the Company’s management with the assistance of a third-party valuation specialist. At September 30, 2022, management determined that the revenue target for the calendar year 2022 was probable of being achieved and a contingent consideration liability of $2.1 million was recognized. At December 31, 2022, management determined that the revenue target for the calendar year 2022 was not achieved, and therefore a change in fair value of contingent consideration of $2.1 million was recognized, resulting in the extinguishment of the contingent consideration liability of $2.1 million. The key inputs into the Monte Carlo simulation as of September 30, 2022 were as follows: Contingent consideration September 30, 2022 Stock Price $ 35.42 Equity volatility 93.7 % Risk-free interest rate 3.9 % Revenue volatility 30.2 % The following table provides a reconciliation of beginning and ending balances of the Level 3 financial liabilities during the six months ended March 31, 2023: (in thousands) Total Balance as of September 30, 2022 $ 2,100 Change in fair value (2,100) Balance as of March 31, 2023 $ —

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies Legal proceedings The Company may be subject to litigation, claims and disputes in the ordinary course of business. There is an inherent risk in any litigation or dispute and no assurance can be given as to the outcome of any claims. Securities Class Action On December 12, 2022, a putative securities class action lawsuit captioned Peters v. Twist Bioscience Corporation, et al., Case No. 22-cv-08168 (N.D. Cal.) (“Securities Class Action”) was filed in federal court in the Northern District of California (“Court”). The Securities Class Action names the Company and certain of its officers as defendants and asserts claims under sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated thereunder. The Securities Class Action’s claims are based in large part on allegations made in a report issued on November 15, 2022 by Scorpion Capital (“Scorpion Report”) concerning, among things, the Company’s DNA chip technology and accounting practices. The initial complaint filed in the Securities Class Action alleges that various statements that the defendants made between December 13, 2019 and November 14, 2022 were materially false and misleading in light of the allegations in the Scorpion Report, and seeks unspecified damages on behalf of all persons and entities who purchased or acquired Company securities during an alleged class period that began on December 13, 2019 and ended on November 14, 2022, as well as certain other costs. This case remains in the preliminary stage. Given the inherent uncertainty of litigation and the legal standards that must be met, including class certification and success on the merits, the Company cannot express an opinion on the likelihood of an unfavorable outcome or on the amount or range of any potential loss. The Company and the other defendants intend to vigorously defend themselves against the claims asserted against them. Indemnifications In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend the indemnified parties for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third-party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. To date, the Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. The Company has also entered into indemnification agreements with its directors and officers that may require it to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by corporate law. The Company also has directors’ and officers’ insurance. Leases The Company leases certain of its facilities under non-cancellable operating leases expiring at various dates through 2044. The Company is also responsible for utilities, maintenance, insurance, and property taxes under these leases. The Company's lease payments consist primarily of fixed rental payments for the right to use the underlying leased assets over the lease terms, as well as payments for common-area-maintenance and administrative services. The Company often receives customary incentives from its landlords, such as reimbursements for tenant improvements and rent abatement periods, which effectively reduce the total lease payments owed for these leases. Leases are classified as operating or financing at commencement. The Company does not have any material financing leases. Certain leases include options to renew or terminate at the Company’s discretion. The lease terms include periods covered by these options if it is reasonably certain the Company will renew or not terminate. The Company’s lease agreements do not contain any material residual value guarantees or restrictive covenants. Supplemental balance sheet information related to the Company’s operating leases as of March 31, 2023 is as follows: (in thousands) March 31, Assets: Operating lease right-of-use asset $ 70,669 Current liabilities: Current portion of operating lease liabilities $ 13,396 Noncurrent liabilities: Operating lease liabilities, net of current portion $ 77,824 Future minimum lease payments under all non-cancelable operating leases that have commenced as of March 31, 2023 are as follows: (in thousands) Operating Years ending September 30: Remainder of 2023 $ 7,480 2024 14,194 2025 14,066 2026 12,609 2027 7,265 Thereafter 90,968 Total minimum lease payments $ 146,582 Less: imputed interest (55,362) Total operating lease liabilities $ 91,220 Less: current portion (13,396) Operating lease liabilities, net of current portion $ 77,824 The statement of cash flows for the six months ended March 31, 2023, include changes in right-of-use assets and operating lease liabilities of $4.3 million and $3.7 million, respectively.

Income taxes	Income taxesIn determining quarterly provisions for income taxes, the Company uses the annual estimated effective tax rate applied to the actual year-to-date profit or loss, adjusted for discrete items arising in that quarter. The Company’s annual estimated effective tax rate differs from the U.S. federal statutory rate primarily as a result of state taxes, foreign taxes, and changes in the Company’s valuation allowance against its deferred tax assets. For the three and six months ended March 31, 2023, the Company recorded provisions for income taxes of $0.7 million and $0.8 million, respectively. For the three and six months ended March 31, 2022, the Company recorded $0.1 million and $10.6 million, respectively, of income tax benefit due to the deferred tax liability assumed as part of a business acquisition.

Share-Based Payment Arrangement [Abstract]
Stock-based compensation	Stock-based compensation The Company grants stock-based awards, consisting of stock options and restricted stock, to its employees, certain non-employee consultants and certain members of its board of directors. The Company measures stock-based compensation expense for restricted stock and stock options granted to its employees and directors on the date of grant and recognizes the corresponding compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. The Company measures stock-based compensation expense for restricted stock and stock options granted to non-employee consultants on the date of grant and recognizes the corresponding compensation expense of those awards over the period in which the related services are received. The Company adjusts for actual forfeitures as they occur. 2018 Equity Incentive Plan On September 26, 2018, the board of directors adopted the 2018 Equity Incentive Plan (the 2018 Plan) as a successor to the 2013 Stock Plan (the 2013 Plan). Any shares subject to outstanding awards under the 2013 Plan that are canceled or repurchased subsequent to the 2018 Plan’s effective date are returned to the pool of shares reserved for issuance under the 2018 Plan. Awards granted under the 2018 Plan may be non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, and performance units. Restricted Stock Units Restricted stock consists of restricted stock unit awards (RSUs) which have been granted to employees and non-employee directors. The value of an RSU award is based on the Company’s stock price on the date of grant. Employee grants generally vest over four years and non-employee director grants generally vest over one year. Forfeitures of RSUs are recognized as they occur. The shares underlying the RSU awards are not issued until the RSUs vest. Upon vesting, each RSU converts into one share of the Company’s common stock. Activity with respect to the Company’s restricted stock units during the six months ended March 31, 2023 was as follows: (in thousands, except per share data) Shares Weighted average grant date fair value per share Nonvested shares at September 30, 2022 1,566 $ 67.66 Granted 851 27.36 Vested/Issued (290) 59.99 Forfeited (290) 77.74 Nonvested shares at March 31, 2023 1,837 $ 48.58 As of March 31, 2023, there was $82.0 million of total unrecognized compensation cost related to these awards that is expected to be recognized over a weighted average period of 2.8 years. The total grant date fair value of RSUs awarded during the six months ended March 31, 2023 was $23.3 million. Performance Stock Units Performance stock unit awards (“PSUs”) granted to certain employees will vest upon achievement of operational milestones related to the Wilsonville facility, and Company executives will vest upon achievement of revenue and gross profit metrics as determined by the board of directors, and to certain non-employee consultants will vest upon achievement of operational milestones. Stock compensation expense for PSUs is recorded over the vesting period based on the grant date fair value of the awards and probability of the achievement of specified performance targets. The grant date fair value is equal to the closing share price of the Company’s common stock on the date of grant. For Company executives and employees, PSUs generally vest over a one one Activity under the PSUs during the six months ended March 31, 2023 is summarized below: (in thousands, except per share data) Shares Weighted average grant date fair value per share Nonvested shares at September 30, 2022 529 $ 79.60 Granted 480 28.14 Vested/Issued (18) 51.08 Forfeited (196) 84.83 Nonvested at March 31, 2023 795 $ 47.87 As of March 31, 2023, the maximum unrecognized compensation costs related to these awards was $27.0 million, based on 150% achievement of the performance target. The Company expects to recognize those costs over a weighted average period of 1.6 years. The total grant date fair value of PSUs awarded during the six months ended March 31, 2023 was $13.5 million. Options Stock options are generally granted to employees and were granted to non-employee directors until fiscal year 2020. Stock options entitle the holder to purchase, at the end of the vesting term, a specified number of shares of Company common stock at an exercise price per share equal to the closing market price of the common stock on the date of grant. Stock options have a contractual life from the date of the grant and a vesting schedule as established by the board of directors. The maximum term of stock options granted under the 2018 Plan is 10 years and the awards generally vest over a four-year period. Forfeitures of options are recognized as they occur. The fair value of each service based stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The Company historically had been a private company and lacked company-specific historical and implied volatility information for its stock. Therefore, it estimated its expected stock price volatility based on the historical volatility of publicly traded peer companies through the period ended March 31, 2023 and utilized the “simplified” method for awards that qualify as “plain-vanilla” options. As determined under the simplified method, the expected term of stock options granted is calculated based on contractual and vesting terms of the option award, the risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award, the expected dividend yield is zero based on the fact that the Company has never paid cash dividends on common stock and does not expect to pay any cash dividends in the foreseeable future. Options activity during the six months ended March 31, 2023 is summarized below: (in thousands, except per share data) Shares Weighted average exercise price per share Weighted average remaining contractual term (years) Aggregate intrinsic value Outstanding at September 30, 2022 2,453 $ 24.67 6.33 $ 33,447 Granted — — — — Forfeited (71) 35.15 — — Exercised (58) 14.86 — 639 Outstanding at March 31, 2023 2,324 $ 24.59 5.78 $ 4,250 Nonvested at March 31, 2023 290 36.46 6.74 100 Exercisable 2,034 $ 22.90 5.65 $ 4,150 As of March 31, 2023, the unrecognized compensation costs related to these awards was $6.7 million. The Company expects to recognize those costs over a weighted average period of 1.1 years. Performance-Based Stock Options On September 1, 2020, the board of directors approved the implementation of a revised annual equity award program for executive officers, senior level employees and consultants to be granted as performance-based stock options ("PSOs") under the 2018 Plan. The number of PSOs ultimately earned in fiscal year 2022 by executive officers and senior level employees was calculated based on the achievement of a certain total revenue threshold during the fiscal year ended September 30, 2022. The percentage of performance stock options that vest depends on the board of directors’ determination of total revenue at the end of the performance period and can range from 0% to 150% of the number of options granted. For fiscal year 2022, the achievement was determined to be 150%. The number of PSOs ultimately earned under the awards to a consultant is calculated based on the achievement of certain operational milestones. The maximum term of performance stock options granted under the 2018 Plan is 10 years for both employees and non-employees. The awards generally vest over a two-year period for executive officers and senior level employees. Awards to non-employees generally vest over a five-year period. The provisions of a PSO are considered a performance condition, and the effects of that performance condition are not reflected in the grant date fair value of the awards. The Company used the Black-Scholes method to calculate the fair value at the grant date without regard to the vesting condition and will recognize compensation cost for the options that are expected to vest. Forfeitures of PSOs are recognized as they occur. The Company reassesses the probability of the performance condition at each reporting period and adjusts the compensation cost based on the probability assessment. As of March 31, 2023, the Company determined that 56,250 shares are expected to vest based on the probability of the performance condition that will be achieved under this equity award program. Activity under the PSOs during the six months ended March 31, 2023 is summarized below: (in thousands, except per share data) Shares Weighted average exercise price per share Weighted average remaining contractual term (years) Aggregate intrinsic value Outstanding at September 30, 2022 312 $ 61.35 8.33 $ 296 Exercisable at September 30, 2022 19 $ 31.29 9.57 $ 74 Nonvested at September 30, 2022 293 63.27 8.25 222 Vested (237) $ 70.84 — $ — Nonvested at March 31, 2023 56 $ 31.29 9.07 $ — Exercisable at March 31, 2023 256 67.95 7.56 — Outstanding at March 31, 2023 312 $ 61.35 7.83 $ — As of March 31, 2023, the unrecognized compensation costs related to these awards was $0.6 million.

An immaterial amount of stock-based compensation was capitalized to inventories attributable to employees who support the manufacturing of the Company's products for the three and six months ended March 31, 2023. The balance sheet as of March 31, 2023 includes $1.1 million of stock-based compensation primarily related to the implementation of the Company’s lab production software system and order management system, which was capitalized in property and equipment. 2018 Employee Stock Purchase Plan On September 26, 2018, the board of directors adopted the 2018 Employee Stock Purchase Plan (the "2018 ESPP"). The number of shares reserved for issuance under the 2018 ESPP upon approval was 275,225 shares of the Company’s common stock, and it increases automatically on the first day of each fiscal year, following the fiscal year in which the 2018 ESPP becomes effective, by a number equal to the least of 249,470 shares, 1% of the shares of common stock outstanding at that time, or such number of shares determined by the Company’s board of directors. The number of shares reserved for issuance at March 31, 2023 was as follows: (In thousands) Shares Reserved at September 30, 2022 507 Additional shares authorized 249 Shares issued during the period (132) Reserved at March 31, 2023 624 Subject to any plan limitations, the 2018 ESPP allows eligible service providers (through qualified and non-qualified offerings) to contribute, normally through payroll deductions, up to 15% of their earnings for the purchase of the Company’s common stock at a discounted price per share. The offering periods begin in February and August of each year, except the initial offering period which commenced with the initial public offering in October 2018 and ended on August 20, 2019. Unless otherwise determined by the board of directors, the Company’s common stock will be purchased for the accounts of employees participating in the 2018 ESPP at a price per share that is the lesser of 85% of the fair market value of the Company’s common stock on the first trading day of the offering period or 85% of the fair market value of the Company’s common stock on the last trading day of the offering period. During the three and six months ended March 31, 2023 and 2022, activity under the 2018 ESPP was immaterial. 401(k) Savings Plan During 2018, the Company adopted a 401(k) savings plan for the benefit of its employees. In January 2022, the Company modified its plan to include an employer matching contribution. The Company is required to make matching contributions to the 401(k) plan equal to 50% of the first 6% of wages deferred by each participating employee. The Company incurred expenses for employer matching contributions of $0.7 million and $1.4 million for the three and six months ended March 31, 2023, respectively. Abveris Acquisition

Business Combination and Asset Acquisition [Abstract]
Business acquisition	Business acquisition On December 1, 2021, the Company acquired all of the outstanding stock of AbX Biologics, Inc. (“Abveris”), a privately-held company providing in vivo antibody discovery services. The acquisition date fair value of the consideration transferred for Abveris was $102.6 million, consisting of cash totaling $9.5 million, 759,601 shares of the Company’s common stock valued at $66.1 million based on the Company’s closing stock price on December 1, 2021, employee stock awards issued to certain Abveris employees valued at $6.4 million, contingent consideration of $8.5 million, holdbacks of $12.8 million, and an estimated net working capital adjustment of $0.7 million. The contingent consideration was subject to the attainment of the calendar year 2022 revenue target. The contingent consideration was payable after December 31, 2022 in a combination of cash and up to 334,939 shares of the Company’s common stock. The acquisition date fair value of the contingent consideration was based on forecasted revenue of Abveris relative to the 2022 revenue target as well as the Company’s stock price as of December 1, 2021. The Company maintains an indemnity and adjustment holdback for the purposes of providing security against any adjustment to the amounts at closing. The indemnity holdback period extends for 18 months from the anniversary of the closing date. The indemnity holdback will be settled by transferring up to 128,351 shares of the Company’s stock, options to purchase up to 15,304 shares of the Company’s common stock and an immaterial amount of cash. The fair value of the indemnity holdback was $12.5 million as of the acquisition date. The adjustment holdback represented up to 3,416 shares of the Company’s stock, options to purchase up to 408 shares of the Company’s common stock and an immaterial amount of cash. The holdback adjustment liability was $0.3 million as of the acquisition date. During the six months ended March 31, 2023, the adjustment holdback liability was settled by transferring 538 shares. As of the acquisition date, post-combination compensation expense excluded from the purchase price included employee stock awards issued to certain Abveris employees valued at $41.0 million. This included awards valued at $17.7 million which vest over a two year service period following the acquisition date and awards valued at $3.2 million with no future vesting requirements, which were deemed accelerated by the Company at the acquisition date and expensed within the three months ended December 31, 2021. Finally, post-combination expense included awards initially valued at approximately $20.1 million which may have vest based on achievement of the calendar year 2022 revenue target and continuing employment through the payout date, and for certain employees, additional continuing employment through the two year anniversary of the acquisition date. At the conclusion of the measurement period ended December 31, 2022, management determined that the revenue target associated with the performance based awards was not met, and therefore none of these awards vested. The following table summarizes the final fair value amounts of the assets acquired and liabilities assumed as of the acquisition date, as well as the purchase consideration: (in thousands) December 1, 2021 Assets acquired Cash and cash equivalents $ 1,306 Accounts receivable 2,309 Other current assets and prepaid expenses 1,654 Property, plant and equipment 1,078 Other non-current assets 2,970 Intangible assets 46,500 Liabilities assumed Current liabilities 3,549 Non-current liabilities 846 Deferred tax liability 10,545 Fair value of assets acquired and liabilities assumed $ 40,877 Goodwill 61,768 Total purchase price $ 102,645 Consideration transferred Cash $ 9,467 Company common stock 72,514 Contingent consideration 8,500 Holdback liabilities 12,838 Net working capital adjustment (674) Fair value of purchase consideration $ 102,645 The following table summarizes the estimate of the intangible assets as of the acquisition date: (in thousands except for years) Estimated Estimated Fair Developed technology 14 $ 30,900 Customer relationships 10 14,700 Trade name 3 900 Estimated fair value of acquired intangible assets $ 46,500 The following table provides a reconciliation of contingent consideration and holdback balances from acquisition date to March 31, 2023: (in thousands) Contingent Holdback Total Balance at December 1, 2021 – acquisition date $ 8,500 $ 12,164 $ 20,664 Change in fair value during the period (6,400) (7,071) (13,471) Balance at September 30, 2022 $ 2,100 $ 5,093 $ 7,193 Change in fair value during the period (2,100) (2,921) (5,021) Balance at March 31, 2023 $ — $ 2,172 $ 2,172 The estimated fair value of the contingent consideration liability decreased as the revenue target for calendar year 2022 was not achieved. The estimated fair value of the holdback liability decreased as a result of the change in the Company’s stock price as of March 31, 2023. For the six months ended March 31, 2023, the Company recognized a gain of $5.0 million relating to the change in fair value of acquisition consideration in its condensed consolidated statement of operations. Issuance of contingent consideration for iGenomX acquisition In December 2022, the Company determined that the indemnity holdback condition specified in the iGenomX acquisition agreement had been met, and the Company became obligated to issue 171,551 shares of its common stock to satisfy the indemnity holdback. The shares of common stock, valued at $4.1 million, were subsequently issued by the Company during January 2023 along with an immaterial cash payment for fractional shares.

Subsequent Events [Abstract]
Subsequent events	Subsequent events 2023 Restructuring Plan On May 3, 2023, the Company’s Board of Directors approved a strategic restructuring plan to reduce costs, build a leaner organization and increase operating efficiencies. The restructuring plan includes a reduction in force affecting approximately 270 employees worldwide, representing approximately 25% of the Company’s total workforce. The reduction in force will be subject to local regulatory requirements. The Company expects the plan to be implemented beginning in the third quarter of fiscal year 2023 and be substantially completed by the end of fiscal year 2023. The Company expects to incur pre-tax charges of between $9 million and $11 million consisting of employee severance and related benefit costs. In addition, the Company expects that it may incur additional charges related to facility consolidation and asset impairments that it is currently not able to estimate. The Company’s estimates are subject to a number of assumptions, and actual results may materially differ. The Company may also incur additional costs not currently contemplated due to events that may occur as a result of, or that are associated with, the restructuring plan. * * * * *

Accounting Policies [Abstract]
Basis of presentation and use of estimates	Basis of presentation and use of estimates The accompanying unaudited condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2022 (the Annual Report on Form 10-K) filed with the Securities and Exchange Commission on November 28, 2022. The condensed consolidated financial statements are unaudited and have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and include, in the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair statement of the condensed consolidated financial statements. The condensed consolidated balance sheet at September 30, 2022 is derived from audited consolidated financial statements but does not include all disclosures required by GAAP. The operating results for the three and six months ended March 31, 2023 are not necessarily indicative of the results expected for the full year ending September 30, 2023 or any interim period. The presentation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Certain prior year amounts have been reclassified to conform to the current year presentation. The Company’s unaudited condensed consolidated financial statements include its wholly owned subsidiaries. All intercompany balances and accounts are eliminated in consolidation.
Revenue	Based on the nature of our contracts with customers, which are recognized over a term of less than 12 months, we have elected to use the practical expedient whereby costs to obtain a contract are expensed as they are incurred. We state our revenues net of any taxes collected from customers that are required to be remitted to various government agencies. The amount of taxes collected from customers and payable to governmental entities is included on the balance sheet as part of “Accrued expenses and other current liabilities.”
Recent accounting pronouncements	Recent accounting pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). The Company considered the applicability and impact of all recent ASUs. ASUs not listed below were assessed and determined to be not applicable to the Company’s consolidated financial position and results of operations. Recent accounting pronouncements adopted In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. The amendments in this update require the annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model. The Company adopted this standard effective October 1, 2022. The adoption of ASU-2021-10 did not have an impact on the Company’s condensed consolidated financial statements as of and for the period ended March 31, 2023. Recently issued accounting pronouncement not yet adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard requires entities to use the new “expected credit loss” impairment model for most financial assets measured at amortized cost, including trade and other receivables and held-to-maturity debt securities, and modifies the impairment model for available-for-sale debt securities. The standard is effective for the Company for the
