Amendment Description	EXPLANATORY NOTERepligen Corporation (“we,” “us,” “our,” or the “Company”) is filing this Amendment No. 1 on Form 10-Q/A (the “Amendment”) to amend and restate certain items in our Quarterly Report on Form 10-Q as of and for the three month period ended March 31, 2023, originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 2, 2023 (the “Original Report”), as listed in “Items Amended in this Filing” below. In filing this Amendment, we are restating our previously issued unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2023 to correct the misapplication of accounting principles under U.S. GAAP related to the timing of revenue recognition arising from a specific COVID-related cancellation payment, received in connection with a contract modification (collectively, the "Misstatement"), as further described in Note 1 to the unaudited condensed consolidated financial statements herein. This restatement changes the timing of recognition of revenue, including the revenue reported in the Original Report, but will not change the total revenue to be recognized for this payment, nor have any impact on the Company’s previously reported cash and cash equivalent balances. This misapplication did not result from any override of controls, misconduct, or fraud of any kind. In connection with the restatement, the Company determined that it was appropriate to revise the condensed consolidated balance sheet as of December 31, 2022 and the condensed consolidated statement of cash flows for the three month period ended March 31, 2022, as well as impacted footnote disclosures, in this Form 10-Q/A to correct other unrelated immaterial errors. In addition, we are filing an amendment to our Annual Report on Form 10-K for the year ended December 31, 2023, originally filed with SEC on February 22, 2024, and amendments to our Quarterly Reports on Form 10-Q for the quarterly periods ended June 30, 2023, originally filed with the SEC on August 2, 2023; September 30, 2023, originally filed with the SEC on October 31, 2023; March 31, 2024, originally filed with the SEC on May 1, 2024; and June 30, 2024, originally filed with the SEC on July 30, 2024. In correcting the Misstatement in this Amendment, we have also restated other financial statement line item amounts including but not limited to product revenues, income tax provision, net income, foreign currency translation, deferred revenues, prepaid expenses, deferred taxes and earnings-per-share.

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Financial Statements	1. Restatement of Previously Issued Financial Statements Subsequent to the issuance of the Original Report on May 2, 2023, the Company identified a material accounting error related to the timing of revenue recognition which impacts the Company’s condensed consolidated financial statements as of and for the three month period ended March 31, 2023 ("the Misstatement"). Within this report, the Company has restated all impacted financial information and footnote disclosures impacted by the Misstatement. A description of the error and its impact on the previously issued financial statements is included below. In connection with the restatement, the Company determined that it was appropriate to revise the condensed consolidated balance sheet as of December 31, 2022 and the condensed consolidated statement of cash flows for the three month period ended March 31, 2022, as well as impacted footnote disclosures, in this Form 10-Q/A to correct other unrelated immaterial errors. Description of revenue restatement adjustments During the first quarter of 2023, a customer cancelled two COVID-related, non-cancellable product purchase orders (“Cancelled PO’s”) in exchange for a $ 17.3 million one-time cash payment (the “Payment”), which was received in April 2023. At the time of cancellation, no product units had been delivered under the Cancelled PO’s and the Company had two other purchase orders from the same customer for the same product (“Open PO’s”). The Company originally accounted for the Cancelled PO’s as a single contract and recognized the $ 17.3 million payment as component of product revenue in the first quarter of 2023. Subsequent to the issuance of the Original Report, the Company reassessed the accounting treatment of the Payment and concluded that the Cancelled PO’s and Open PO’s represented a combined contract such that the February 2023 transaction should have been analyzed and accounted for as a contract modification, which required the Payment to be deferred and recognized as product units were delivered under the Open PO’s. All Open PO product units were fully delivered to the customer by June 30, 2024; no Open PO product units were delivered in the three month period ended March 31, 2023. The correction of the Misstatement affects certain financial statement line items in these condensed consolidated financial statements including but not limited to product revenues, income tax provision, foreign currency translation, deferred revenues, prepaid expenses, deferred taxes and earnings-per-share. Consolidated Financial Statements - Restatement Reconciliation Tables The following tables present the impact of the financial statement adjustments on the Company's previously reported condensed consolidated financial statements. The "Previously Reported" amounts in the following tables are amounts derived from the Original Report. The amounts in the columns labeled "Revenue Adjustments" represent the effect of adjustments resulting from the correction of the overstatement of revenues associated with the Payment and related tax impact. The amounts in the columns labeled "Other Adjustments" represent the effect of other adjustments that relate to other unrelated errors in previously filed financial statements that were not material, individually or in the aggregate, to those filed financial statements. The effects of both the restatement for the Revenue Adjustments and the immaterial Other Adjustments have been corrected in all impacted tables and footnotes throughout these condensed consolidated financial statements.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The condensed consolidated financial statements included herein have been prepared by Repligen Corporation in accordance with generally accepted accounting principles accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”), for Quarterly Reports on Form 10-Q and Article 10 of Regulation S-X and do not include all of the information and footnote disclosures required by GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the SEC on February 22, 2023 (“Form 10-K”). The preparation of 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 at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The business and economic uncertainty resulting from government-mandated actions in response to the COVID-19 pandemic, including all subsequent variants of the SARS-CoV-2 coronavirus ("COVID-19"), the Russia-Ukraine conflict, supply chain challenges, cost pressure and the overall effects of the current high inflation environment on customers' purchasing patterns has made such estimates more difficult to calculate. Accordingly, actual results could differ from those estimates. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Repligen Sweden AB, Repligen GmbH, Spectrum ® LifeSciences LLC and its subsidiaries (“Spectrum”), C Technologies, Inc., ARTeSYN Biosolutions Holdings Ireland Ltd., ARTeSYN Biosolutions Ireland Limited and its subsidiaries ("ARTeSYN"), Polymem S.A. (“Polymem”), Avitide LLC ("Avitide"), Newton T&M Corp. ("NTM"), Bio-Flex Solutions, L.L.C. ("BioFlex"), Repligen Singapore Pte. Ltd. and Repligen UK Limited. All significant intercompany accounts and transactions have been eliminated in consolidation. Except for the change in the Company's policy on Convertible Senior Notes, which the Company adopted effective January 1, 2022 as required by Accounting Standards Update No. ("ASU" or "ASUs") 2020-06 and discussed in Note 6, "Convertible Senior Notes," to these condensed consolidated financial statements, the Company made no material changes in the application of its significant accounting policies that were disclosed in its Form 10-K. In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of only normal, recurring adjustments necessary for a fair presentation of its financial position as of March 31, 2023, its results of operations for the three months ended March 31, 2023 and 2022 and cash flows for the three months ended March 31, 2023 and 2022. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the entire year. Certain prior year balances have been reclassified to conform to current year presentation. Recent Accounting Standards Updates We consider the applicability and impact of all ASUs on the Company’s condensed consolidated financial statements. As of March 31, 2023, there were no accounting standards or ASUs recently issued or effective during the fiscal year that would have a material effect on the Company's condensed consolidated financial statements or disclosures.

Fair Value Measurements

Fair Value Measurements	3 Months Ended
	Mar. 31, 2023
Disclosure Text Block [Abstract]
Fair Value Measurements	3. Fair Value Measurements The Company uses various valuation approaches in determining the fair value of its assets and liabilities. The Company employs a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. The fair value hierarchy is broken down into three levels based on the source of inputs as follows: Level 1 - Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access Level 2 - Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement. Cash, Cash Equivalents and Marketable Securities Held to Maturity The following table summarizes the Company's cash, cash equivalents and marketable securities held to maturity as of March 31, 2023 and December 31, 2022 (amounts in thousands): As of March 31, 2023 Amortized Gross Gross Estimated Cash and cash equivalents: Cash and money market funds $ 516,609 $ — $ — $ 516,609 Total cash and cash equivalents 516,609 — — 516,609 Marketable securities held to maturity: U.S. treasury bills - short-term 101,409 58 — 101,467 Total cash, cash equivalents and marketable securities $ 618,018 $ 58 $ — $ 618,076 As of December 31, 2022 Amortized Gross Gross Estimated Cash and cash equivalents: Cash and money market funds $ 523,458 $ — $ — $ 523,458 Total cash and cash equivalents 523,458 — — 523,458 Marketable securities held to maturity: U.S. treasury bills - short-term 100,299 24 — 100,323 Total cash, cash equivalents and marketable securities $ 623,757 $ 24 $ — $ 623,781 During the fourth quarter of 2022, the Company purchased $ 100.0 million of 6-month U.S. treasury bills with the positive intent and ability to hold them until maturity. Therefore, the Company classified this investment as held to maturity and stated it at amortized cost on the condensed consolidated balance sheet. The amortized cost and the fair value of the Company's held to maturity securities by contractual maturity at March 31, 2023 and December 31, 2022 are summarized below: March 31, 2023 December 31, 2022 Amortized Estimated Amortized Estimated Maturity of one year or less $ 101,409 $ 101,467 $ 100,299 $ 100,323 Total $ 101,409 $ 101,467 $ 100,299 $ 100,323 Fair Value Measured on a Recurring Basis Financial assets and financial liabilities measured at fair value on a recurring basis consist of the following as of March 31, 2023 and December 31, 2022 (amounts in thousands): As of March 31, 2023 Level 1 Level 2 Level 3 Total Assets: Money market accounts $ 339,044 $ — $ — $ 339,044 Liabilities: Short-term contingent consideration (1) $ — $ — $ 27,834 $ 27,834 Long-term contingent consideration $ — $ — $ 38,910 $ 38,910 As of December 31, 2022 Level 1 Level 2 Level 3 Total Assets: Money market accounts $ 343,929 $ — $ — $ 343,929 Liabilities: Short-term contingent consideration $ — $ — $ 13,950 $ 13,950 Long-term contingent consideration $ — $ — $ 51,559 $ 51,559 (1) The $ 27.8 million of short-term contingent consideration includes $ 14.5 million due and payable to the remaining securityholders of Avitide related to the First Earnout Year as defined in the Agreement and Plan of Merger and Reorganization with Avalon Merger Sub, Inc., which the Company entered into as part of the acquisition of Avitide in 2021. This amount is anticipated to be paid in the second quarter of 2023. Contingent Consideration – Earnout As of March 31, 2023 , the maximum amount of future contingent consideration (undiscounted) that we could be required to pay in connection with the completed acquisition of Avitide, was $ 125.0 million. Refer to Note 4, "Acquisitions" included in Part II, Item 8, “ Financial Statements and Supplementary Data” to our Form 10-K for additional information on the contingent consideration. During 2023, a change in market inputs used to calculate the discount rate resulted in an increase in amounts reported as of March 31, 2023 . A reconciliation of the change in the fair value of contingent consideration - earnout is included in the following table (amounts in thousands): Balance at December 31, 2022 $ 65,509 Increase in fair value of contingent consideration earnouts 1,235 Balance at March 31, 2023 $ 66,744 The recurring Level 3 fair value measurement of our contingent consideration earnout that we expect to be required to settle our 2023 and 2024 contingent consideration obligation include the following significant unobservable inputs (amounts in thousands, except percent data): Contingent Consideration Earnout Fair Value as of Valuation Technique Unobservable Input Range Weighted Average (1) Probability of Commercialization-based Monte Carlo Success 100 % 100 % payments $ 18,974 Simulation Earnout Discount Rate 5.9 %- 6.1 % 6.0 % Volatility 23.6 % 23.6 % Revenue and Volume- Monte Carlo Revenue & Volume based payments $ 33,301 Simulation Discount Rate 6.4 % 6.4 % Earnout Discount Rate 5.9 %- 6.1 % 6.0 % (1) Unobservable inputs were weighted by the relative fair value of the contingent consideration liability.

Because substantially all of its revenues are from bioprocessing customers, there are no differences in the nature, timing and uncertainty of the Company’s revenues and cash flows from any of its product lines. However, given that the Company’s revenues are generated in different geographic regions, regulatory, economic and geopolitical factors within those regions could impact the nature, timing and uncertainty of the Company’s revenues and cash flows. In addition, a significant portion of the Company’s revenue is generated from a small number of customers; therefore, economic factors specific to these customers could impact the nature, timing and uncertainty of the Company’s revenues and cash flows. Disaggregated revenue from contracts with customers by geographic region and revenue from significant customers can be found in Note 13, “Segment Reporting,” included in this report. For more information regarding our product revenue, see Note 6, “Revenue Recognition” included in Part II, Item 8, “ Financial Statements and Supplementary Data” to our Form 10-K.

Convertible Senior Notes	7. Convertible Senior Notes 0.375% Convertible Senior Notes due 2024 On July 19, 2019, the Company issued $ 287.5 million aggregate principal pursuant to the 2019 Notes, which includes the underwriters’ exercise in full of an option to purchase an additional $ 37.5 million aggregate principal amount of 2019 Notes (the “Notes Offering”). The net proceeds of the Notes Offering, after deducting underwriting discounts and commissions and other related offering expenses payable by the Company, were approximately $ 278.5 million. The 2019 Notes are senior, unsecured obligations of the Company, and bear interest at a rate of 0.375 % per year. Interest is payable semi-annually in arrears on January 15 and July 15 of each year, beginning on January 15, 2020. The 2019 Notes will mature on July 15, 2024 , unless earlier repurchased or converted in accordance with their terms. During the first quarter of 2023, the closing price of the Company’s common stock exceeded 130 % of the conversion price of the 2019 Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the 2019 Notes are convertible at the option of the holders of the 2019 Notes during the second quarter of 2023, the quarter immediately following the quarter when the conditions are met, as stated in the terms of the 2019 Notes. These conditions have been met each quarter since the third quarter of 2020. As a result, $ 39,000 aggregate principal amount of the 2019 Notes have been requested for conversion by the note holders since the issuance of the 2019 Notes, all conversions have settled except for $ 9,000 aggregate principal amount, which settles in the second quarter of 2023. The conversions resulted in the issuance of a nominal number of shares of the Company’s common stock to the note holders. The Company continues to classify the carrying value of the 2019 Notes as current liabilities on the Company’s condensed consolidated balance sheets at March 31, 2023. The net carrying value of the liability component of the 2019 Notes is as follows: March 31, December 31, (Amounts in thousands) 0.375% Convertible Senior Notes due 2024: Principal amount $ 287,470 $ 287,470 Unamortized debt issuance costs ( 2,398 ) ( 2,855 ) Net carrying amount $ 285,072 $ 284,615 The following table sets forth total interest expense recognized related to the 2019 Notes: Three Months Ended 2023 2022 (Amounts in thousands) Contractual interest expense $ 270 $ 270 Amortization of debt issuance costs 457 452 Total $ 727 $ 722 Effective interest rate of the liability component 1 % 1 % At March 31, 2023 and December 31, 2022, the carrying value of the 2019 Notes was $ 285.1 million and $ 284.6 million, respectively, net of unamortized discount, and the fair value of the 2019 Notes was $ 441.8 million and $ 452.0 million, respectively.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the closing price of the common stock on March 31, 2023, the last business day of the first quarter of 2023, of $ 168.36 per share and the exercise price of each in-the-money option) that would have been received by the option holders had all option holders exercised their options on March 31, 2023. The aggregate intrinsic value of stock options exercised during the three months ended March 31, 2023 and 2022 was $ 0.2 million and $ 1.4 million, respectively. The weighted average grant date fair value of options granted during the three months ended March 31, 2023 and 2022 was $ 89.25 and $ 79.96 , respectively. Stock Units The fair value of stock units is calculated using the closing price of the Company’s common stock on the date of grant. The Company recognizes expense on awards with service-based vesting over the employee’s requisite service period on a straight-line basis. The Company recognizes expense on performance-based awards over the vesting period based on the probability that the performance metrics will be achieved.

Commitments and Contingencies	9. Commitments and Contingencies Collaboration Agreements The Company licenses certain technologies that are, or may be, incorporated into its technology under several agreements and also has entered into several clinical research agreements that require the Company to fund certain research projects. Generally, the license agreements require the Company to pay annual maintenance fees and royalties on product sales once a product has been established using the technologies. Research and development expenses associated with license agreements were immaterial amounts for the three months ended March 31, 2023 and 2022. In June 2018, the Company secured an agreement with Navigo Proteins GmbH (“Navigo”) for the exclusive co-development of multiple affinity ligands for which the Company holds commercialization rights. The Company is manufacturing and supplying the first of these ligands, NGL-Impact ® , exclusively to Purolite Life Sciences, an Ecolab Inc. company (“Purolite”), who is pairing the Company’s high-performance ligand with Purolite’s agarose jetting base bead technology used in their Jetted A50 Protein A resin product. The Company also signed a long-term supply agreement with Purolite for NGL-Impact and other potential additional affinity ligands that may advance from the Company’s Navigo collaboration. In September 2020, the Company and Navigo successfully completed co-development of an affinity ligand targeting the SARS-CoV-2 spike protein, to be utilized in the purification of vaccines for the COVID-19 pandemic, including emerging variants of the SARS-CoV-2 coronavirus. The Company has proceeded with scaling up and manufacturing this ligand and the development and validation of the related affinity chromatography resin, which is marketed by the Company. In September 2021, the Company and Navigo successfully completed co-development of a novel affinity ligand that addresses aggregation issues associated with pH sensitive antibodies and Fc-fusion proteins. The Company is manufacturing and supplying this ligand, NGL-Impact ® HipH, to Purolite. The Navigo and Purolite agreements are supportive of the Company’s strategy to secure and reinforce the Company’s proteins business. The Company made royalty payments to Navigo of $ 1.1 million and $ 0.4 million for the three months ended March 31, 2023 and 2022, respectively. Legal Proceedings From time to time, in the normal course of its operations, the Company is subject to litigation matters and claims relating to employee relations, business practices and patent infringement. Litigation can be expensive and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict, and the Company's view of these matters may change in the future as the litigation and events related thereto unfold. The Company expenses legal fees as incurred. The Company records a provision for contingent losses when it is both probably that a liability has been incurred and the amount of the loss can be reasonably estimated. An unfavorable outcome to any legal matter, if material, could have an adverse effect on the Company's operations or its financial results.

Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes (As Restated) For the three months ended March 31, 2023 and 2022, the Company recorded an income tax provision of $ 3.2 million and $ 12.0 million, respectively. The Company’s effective tax rate for the three months ended March 31, 2023 and 2022 was 17.3 % and 20.3 % , respectively. The decrease in effective tax rates between the periods was primarily due to lower income before taxes and increased benefits from business tax credits and windfall benefits recognized on stock option exercises and the vesting of stock units, partially offset by nondeductible contingent consideration and lower foreign-derived intangible income. On August 16, 2022, the United States enacted the Inflation Reduction Act of 2022 ("Inflation Reduction Act"), which, among other things, implements a 15 % alternative minimum tax on global adjusted financial statement income of certain large corporations, a 1 % excise tax on net stock repurchases and several tax incentives to promote clean energy and was effective beginning in 2023. We evaluated the provisions of the Inflation Reduction Act and no provision had a material effect on our consolidation financial position or results of operations.

Earnings Per Share, Basic [Abstract]
Earnings Per Share	11. Earnings Per Share A reconciliation of basic and diluted weighted average shares outstanding is as follows: Three Months Ended 2023 2022 (Amounts in thousands, (As Restated) Numerator: Net income $ 15,337 $ 46,964 Effect of dilutive securities: Charges associated with convertible debt instruments, net of tax — 387 Numerator for diluted earnings per share - net income available to common $ 15,337 $ 47,351 Denominator: Weighted average shares used in computing net income per share - basic 55,590 55,353 Effect of dilutive shares: Options and stock units 529 726 Convertible senior notes 883 2,726 Contingent consideration 44 — Dilutive effect of unvested performance stock units 3 11 Dilutive potential common shares 1,459 3,463 Denominator for diluted earnings per share - adjusted weighted average 57,049 58,816 Earnings per share: Basic $ 0.28 $ 0.85 Diluted $ 0.27 $ 0.81 For the three months ended March 31, 2023 and 2022, 263,871 shares and 137,247 shares, respectively, of the Company’s common stock were excluded from the calculation of diluted EPS because the exercise prices of the stock options were greater than or equal to the average price of the common shares and were therefore anti-dilutive. In July 2019, the Company issued $ 287.5 million aggregate principal amount of the 2019 Notes. As provided by the terms of the indenture underlying the 2019 Notes, prior to March 4, 2022, conversion of the 2019 Notes could have been settled in cash, shares of the Company’s common stock or a combination thereof, at the Company’s election. On March 4, 2022, we entered into the Second Supplemental Indenture for the 2019 Notes, which irrevocably elected to settle the conversion of the 2019 Notes using a combination of cash and shares of the Company’s common stock, settling the par value of the 2019 Notes in cash and any excess conversion premium in shares. As provided by the terms of the Second Supplemental Indenture underlying the 2019 Notes, the Company irrevocably elected to settle the conversion obligation for the 2019 Notes in a combination of cash and shares of the Company's common stock. This means the Company will settle the par value of the 2019 Notes in cash and any excess conversion premium in shares. The Company adopted ASU 2020-06 effective January 1, 2022. Under ASU 2020-06, the Company is required to reflect the dilutive effect of the convertible securities by application of the "if-converted" method, which means the denominator of the EPS calculation would include the total number of shares assuming the 2019 Notes had been fully converted at the beginning of the period. Prior to March 4, 2022, the Company had the choice to settle the conversion of the 2019 Notes in cash, stock or a combination of the two. Therefore, from January 1, 2022 (the date the Company adopted ASU 2020-06) to March 4, 2022, the Company included 3,474,429 shares in the denominator of the EPS calculation, applying the if converted method. Subsequent to March 4, 2022, after the Second Supplemental Indenture became effective, the Company irrevocably elected to settle the conversion obligation for the 2019 Notes in a combination of cash and shares of the Company's common stock, and from March 5, 2022 forward, only the excess premium will be settled with shares. Under the if-converted method of calculating dilutive shares, the Company was also required to exclude amortization of debt issuance costs and interest charges applicable to the convertible debt from the numerator of the dilutive EPS calculation for the period from January 1, 2022 to March 4, 2022, as if the interest on convertible debt was never recognized for that period. For the three months ended March 31, 2022, the Company excluded interest charges of $ 0.4 million (net of tax) from the numerator. Prior to the adoption of ASU 2020-06, the Company applied the provisions of ASC 260, “Earnings Per Share,” Subsection 10-45-44, to determine the diluted weighted average shares outstanding as it related to the conversion spread on its convertible notes. Accordingly, the par value of the 2019 Notes was not included in the calculation of diluted income per share, but the dilutive effect of the conversion premium was considered in the calculation of diluted net income per share using the treasury stock method. The dilutive impact of the 2019 Notes was based on the difference between the Company’s current period average stock price and the conversion price of the 2019 Notes, provided there was a premium. Pursuant to this accounting standard, there was no dilution from the accreted principal of the 2019 Notes. For the three months ended March 31, 2023, the dilutive effect of the conversion premium included in the calculation of diluted earnings was 882,599 shares. For the three months ended March 31, 2022, the dilutive effect of the conversion premium included in the calculation of diluted earnings was 2,726,258 shares.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements included herein have been prepared by Repligen Corporation in accordance with generally accepted accounting principles accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”), for Quarterly Reports on Form 10-Q and Article 10 of Regulation S-X and do not include all of the information and footnote disclosures required by GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the SEC on February 22, 2023 (“Form 10-K”). The preparation of 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 at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The business and economic uncertainty resulting from government-mandated actions in response to the COVID-19 pandemic, including all subsequent variants of the SARS-CoV-2 coronavirus ("COVID-19"), the Russia-Ukraine conflict, supply chain challenges, cost pressure and the overall effects of the current high inflation environment on customers' purchasing patterns has made such estimates more difficult to calculate. Accordingly, actual results could differ from those estimates. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Repligen Sweden AB, Repligen GmbH, Spectrum ® LifeSciences LLC and its subsidiaries (“Spectrum”), C Technologies, Inc., ARTeSYN Biosolutions Holdings Ireland Ltd., ARTeSYN Biosolutions Ireland Limited and its subsidiaries ("ARTeSYN"), Polymem S.A. (“Polymem”), Avitide LLC ("Avitide"), Newton T&M Corp. ("NTM"), Bio-Flex Solutions, L.L.C. ("BioFlex"), Repligen Singapore Pte. Ltd. and Repligen UK Limited. All significant intercompany accounts and transactions have been eliminated in consolidation. Except for the change in the Company's policy on Convertible Senior Notes, which the Company adopted effective January 1, 2022 as required by Accounting Standards Update No. ("ASU" or "ASUs") 2020-06 and discussed in Note 6, "Convertible Senior Notes," to these condensed consolidated financial statements, the Company made no material changes in the application of its significant accounting policies that were disclosed in its Form 10-K. In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of only normal, recurring adjustments necessary for a fair presentation of its financial position as of March 31, 2023, its results of operations for the three months ended March 31, 2023 and 2022 and cash flows for the three months ended March 31, 2023 and 2022. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for the entire year. Certain prior year balances have been reclassified to conform to current year presentation.
Recent Accounting Standards Updates	Recent Accounting Standards Updates We consider the applicability and impact of all ASUs on the Company’s condensed consolidated financial statements. As of March 31, 2023, there were no accounting standards or ASUs recently issued or effective during the fiscal year that would have a material effect on the Company's condensed consolidated financial statements or disclosures.
