NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. Summary of Significant Accounting Policies
Basis of Presentation
The condensed consolidated financial statements included herein have been prepared by Repligen Corporation (the “Company”, “Repligen”, “our” or “we”) in accordance with generally accepted accounting principles in the United States (“GAAP”) and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in the audited financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The information included within this Quarterly Report on Form 10-Q 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, 2025, which was filed with the SEC on February 26, 2026 (“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 global geopolitical conflicts, supply chain challenges, foreign currency fluctuations and cost pressures on customers' purchasing patterns has made such estimates more difficult to calculate. Accordingly, actual results could differ from those estimates.
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 results of the interim periods presented. Results of the interim periods presented are not necessarily indicative of results to be expected for the entire year. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
During the three and nine months ended September 30, 2026, the Company made no material changes in the application of its significant accounting policies that were disclosed within Note 2, “Summary of Significant Accounting Policies” included in Part II, Item 8, “Financial Statements and Supplementary Data” to the Company's Form 10-K.
Reclassification
Certain prior year amounts have been reclassified to conform with the current year presentation. Beginning in 2026, “Restructuring activities and other charges” is presented separately on the condensed consolidated statements of comprehensive income or loss. This reclassification has no impact on net income or loss.
Recent Accounting Guidance
The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (“FASB”) and other recently issued guidance or rule decisions on its condensed consolidated financial statements. Updates not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company’s condensed consolidated financial position, results of operations or related disclosures.
Recently Issued Accounting Guidance – Not Yet Adopted
In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires disclosure of specific expense categories in the notes to the financial statements. This includes: (i) amounts of purchased inventory, employee compensation, depreciation, amortization and other related costs and expenses; (ii) an explanation of costs and expenses that are not disaggregated on a quantitative basis; and (iii) the definition and total amount of selling expenses. The amendment is effective for annual reporting periods beginning after December 15, 2026, with early adoption permitted, and interim reporting periods beginning after December 15, 2027. The amendment should be applied prospectively to financial reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and related disclosures.

2. Marketable Securities and Fair Value Measurements
Marketable Securities
In the fourth quarter of 2025, the Company invested in marketable securities, in the form of U.S. Treasury Bills. As of September 30, 2026, and December 31, 2025, the Company’s marketable securities were classified as available-for-sale investments and mature within one year from the balance sheet date. During the three and nine months ended September 30, 2026, the Company did not have any realized gains or losses. During the three and nine months ended September 30, 2026, the Company did not recognize credit losses related to the available-for-sale securities, and there was no allowance for credit losses recorded as of September 30, 2026, and December 31, 2025.
The following tables summarize the Company's marketable securities as of September 30, 2026, and December 31, 2025:

Fair Value Measured on a Recurring Basis
The Company uses various valuation approaches in determining the fair value of its assets and liabilities required to be recorded or disclosed at fair value. 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 observable market based inputs or unobservable inputs that are corroborated by market data, each either directly or indirectly.
Level 3 -Valuations based on inputs that are unobservable or 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.

Financial assets and financial liabilities measured at fair value on a recurring basis consist of the following as of September 30, 2026, and December 31, 2025:

Contingent Consideration – Earnout
In connection with the acquisition of Tantti Laboratory Inc. (“Tantti”), the Company has an obligation to pay a maximum of $54.5 million (undiscounted) in contingent consideration earnouts in cash over a three-year earnout period beginning January 1, 2025, and ending December 31, 2027. During the nine months ended September 30, 2026, the Company paid $5.2 million in cash for the Tantti contingent consideration earnouts. As of September 30, 2026, the estimated fair value of the remaining obligation is $2.3 million, which is classified as current within the condensed consolidated balance sheet.
A reconciliation of the change in fair value of contingent consideration – earnout is included in the following table (amounts in thousands):

Increase in fair value of contingent consideration earnouts1,459 
Earnout payment - cash(5,225)

Balance at September 30, 2026$2,254 
Changes in the projected performance of the acquired business could result in a higher or lower contingent consideration obligation in the future.

Convertible Senior Notes
At September 30, 2026, and December 31, 2025, the fair value of the Company’s 1.00% Convertible Senior Notes due 2028 (the “2023 Notes”) was $652.2 million and $603.1 million, respectively. The fair value of the 2023 Notes is a Level 1 valuation and was determined based on the most recent trade activity of the 2023 Notes as of September 30, 2026, and December 31, 2025. See Note 8, “Convertible Senior Notes”, for additional information.
Fair Value Measured on a Nonrecurring Basis
During the three months ended September 30, 2026, the Company determined the developed-technology intangible assets related to an intellectual property license agreement were impaired, as the asset would not generate future undiscounted cash flows and therefore was not recoverable. Accordingly, the Company recorded a $41.2 million impairment charge, representing the excess of carrying value over fair value. See Note 6, “Goodwill and Intangible Assets”, for more information.
3. Acquisitions and Divestitures
2026 Divestiture
Polymem S.A.S.
On March 30, 2026, the Company completed the sale of Polymem S.A.S. (“Polymem”) for total consideration of $3.6 million, net of cash divested, which was received during the second quarter of 2026. The Company recognized a net loss on the sale during the nine months ended September 30, 2026, of $13.7 million, which was recorded within loss on sale of business on the condensed consolidated statements of comprehensive income or loss.
2025 Acquisition
908 Devices Inc. Bioprocessing Analytics Portfolio
On March 4, 2025, the Company completed its acquisition of 908 Devices Inc.’s (“908 Devices”) desktop portfolio of four devices for bioprocessing process analytical technology applications (“PAT Portfolio”, together with 908 Devices, the “908 Devices PAT Portfolio”). In connection with the transaction, Repligen also acquired facilities, employees, equipment and lease obligations for facilities in North Carolina and Braunschweig, Germany as well as certain working capital balances related to the PAT Portfolio. This transaction is referred to as the 908 Devices PAT Portfolio acquisition.
Consideration Transferred
The Company accounted for the 908 Devices PAT Portfolio acquisition as a purchase of a business in accordance with ASC 805, “Business Combinations.” Under the securities and asset purchase agreement, the PAT Portfolio and associated net assets were acquired for cash consideration of $69.9 million. The assets acquired and liabilities assumed were recorded as of the acquisition date, at their respective fair values and consolidated with those of the Company.
Acquisition-related costs are not included as a component of consideration transferred but are expensed in the periods in which such costs are incurred. The Company has incurred $14.2 million of transaction and integration costs associated with the 908 Devices PAT Portfolio acquisition from the date of acquisition to September 30, 2026, of which $0.4 million and $1.7 million were incurred during the three and nine months ended September 30, 2026, respectively. The transaction and integration costs are included in operating expenses in the condensed consolidated statements of comprehensive income or loss.

Acquired Goodwill
The goodwill of $50.2 million represents future economic benefits expected to arise from anticipated synergies from the integration of the 908 Devices PAT Portfolio into the Company. These synergies include operating efficiencies and strategic benefits projected to be achieved as a result of the 908 Devices PAT Portfolio acquisition. Goodwill is calculated based on the acquired assets in the United States and Germany. Goodwill related to the United States of $39.6 million is deductible for income tax purposes. The goodwill of $10.6 million related to Germany is nondeductible for income tax purposes.

4. Restructuring Activities and Other Charges
2026 Restructuring Activities and Other Charges
During the first quarter of 2026, the Company initiated a series of restructuring activities to simplify the global manufacturing footprint of the organization and align its workforce to support long-term company growth. These activities will include a series of site optimization phases with the purpose of improving operating efficiency. Costs related to these initiatives will primarily consist of severance and employee-related costs and facility and other exit costs.
The Company expects to identify additional actions as it further refines its initiatives in future periods. These charges will be recorded when criteria are met in accordance with ASC 420, “Exit or Disposal Cost Obligations.” The activities included in these initiatives are expected to be substantially complete by the end of 2027.
2025 Restructuring Activities and Other Charges
Beginning in 2023, the Company initiated restructuring activities to simplify and streamline its organization and strengthen the overall effectiveness of operations. The activities continued into 2024 and 2025 and included consolidating a portion of
12
the manufacturing operations between certain U.S. locations, writing-off abandoned equipment with the rationalization of excess production line capacity and discontinuing the sale of certain product SKUs. The Company does not expect to incur further significant charges related to these actions.
The following table summarizes the charges related to restructuring activities and other charges by type of cost for the periods presented within the Company’s condensed consolidated statements of comprehensive income or loss:

5. Revenue Recognition
Disaggregation of Revenue
Revenue for the three and nine months ended September 30, 2026, and 2025 was as follows:
Three Months Ended September 30,Nine Months Ended September 30,
2026202520262025
(Amounts in thousands)
Product revenue$209,270 $188,766 $607,566 $540,232 
Royalty and other revenue44 39 131 111 
Total revenue$209,314 $188,805 $607,697 $540,343 
When disaggregating revenue, the Company considered all of the economic factors that may affect its revenues. Because 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, factors such as regulatory and geopolitical factors within those regions 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.” For more information regarding product revenue, see Note 7, “Revenue Recognition” included in Part II, Item 8, “Financial Statements and Supplementary Data” to the Company's Form 10-K.

During the nine months ended September 30, 2026, the Company recognized $12.0 million of revenue that was deferred and included within accrued liabilities and other noncurrent liabilities as of December 31, 2025. During the nine months
13
ended September 30, 2025, the Company recognized $9.9 million of revenue that was deferred and included within accrued liabilities and other noncurrent liabilities as of December 31, 2024.
The timing of revenue recognition, billings and cash collections results in the accounts receivable and deferred revenue balances on the Company’s condensed consolidated balance sheets.
6. Goodwill and Intangible Assets
Goodwill
The following table represents the change in the carrying value of goodwill for the nine months ended September 30, 2026 (amounts in thousands):
Balance at December 31, 2025$1,114,408 
Divestiture of Polymem(713)
Cumulative translation adjustment(13,376)
Balance at September 30, 2026$1,100,319 
The Company’s annual impairment analysis of goodwill was performed as of October 1, 2026. The qualitative assessment of the Company’s one reporting unit indicated there were no indications of impairment and it was not more likely than not that its fair value was less than its carrying amount.
Intangible assets
Indefinite-lived intangible assets are reviewed for impairment at least annually. Definite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the asset group that includes the definite-lived assets may not be recoverable. The Company reassesses its asset groupings whenever changes in facts and circumstances occur.
During the three months ended September 30, 2026, the Company identified an impairment indicator related to certain definite-lived intangible assets, specific to an intellectual property license agreement, and performed an impairment analysis. Based on the facts and circumstances, these definite-lived intangible assets were determined to be a separate asset group. As a result, the Company determined the developed-technology intangible assets related to the intellectual property license agreement were impaired and recorded a $41.2 million impairment charge, which is included within intangible asset impairment charges on the condensed consolidated statements of comprehensive income or loss.

Carrying amount - Convertible Senior Notes due 2028, net$555,596 $542,213 
1.00% Convertible Senior Notes due 2028
On December 14, 2023, the Company issued $600.0 million aggregate principal amount of its 2023 Notes pursuant to Rule 144A under the Securities Act. The 2023 Notes are senior, unsecured obligations of the Company, and bear interest at a rate of 1.00% per year and have an effective interest rate of 4.39%. Interest is payable semi-annually in arrears on each of June 15 and December 15, which commenced on June 15, 2024. The 2023 Notes will mature on December 15, 2028, unless earlier redeemed, repurchased or converted.
The initial conversion rate for the 2023 Notes is 4.9247 shares of the Company’s common stock per $1,000 principal amount of the 2023 Notes, which is equivalent to an initial conversion price of $203.06 per share and represents a 30% premium over the last reported sale price of $156.20 per share on December 6, 2023, the date on which the 2023 Notes were priced.
The holders of the 2023 Notes may convert all or a portion of such notes prior to the close of business on the business day immediately preceding September 15, 2028 under the following circumstances, as stated in the indenture governing the 2023 Notes (the “2023 Notes Indenture”):
•During any calendar quarter (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;
•During the five-business day period immediately after any five consecutive trading day period (the “measurement period") in which the trading price (as defined in the 2023 Notes Indenture) per $1,000 principal amount of the 2023 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; and
•If the Company calls the 2023 Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or
•Upon occurrence of a specific corporate events as set forth in the 2023 Notes Indenture.
Prior to the close of business on the business day immediately preceding September 15, 2028, the 2023 Notes will be convertible at the option of the holders of the 2023 Notes, only upon the satisfaction of the specified conditions described above, into cash up to their principal amount, and into cash, shares of the Company’s common stock or a combination thereof, at the Company’s election, for the conversion value above the principal amount, if any. Thereafter until the close of business on the second scheduled trading day immediately preceding the maturity date, December 15, 2028, the 2023 Notes will be convertible at the option of the holders of the 2023 Notes at any time regardless of these specified conditions.
The Company may redeem for cash, all or a portion of the 2023 Notes, at its option, on or after December 18, 2026 and prior to the 21st scheduled trading day immediately preceding the maturity date at a redemption price of 100% of the principal amount of the 2023 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, if certain conditions are met in accordance with the 2023 Notes Indenture.
The conditional conversion features of the 2023 Notes were not triggered during the calendar quarter ended September 30, 2026, therefore, the 2023 Notes are not convertible during the calendar quarter ended December 31, 2026, pursuant to the applicable last reported sales price conditions.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value that would have been received by the option holders had all option holders exercised their options on September 30, 2026. The aggregate intrinsic value of stock options exercised was $27.0 million and $4.3 million during the nine months ended September 30, 2026, and 2025, respectively.
The weighted average grant date fair value of options granted during the nine months ended September 30, 2026, and 2025 was $64.21 and $72.94, 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 subject to market conditions over the employee’s requisite service period on a straight-line basis, while performance-based awards subject to financial performance conditions are recognized over the vesting period based on the probability that the performance metrics will be achieved. Information regarding stock unit activity, which includes activity for restricted stock units and performance stock units, for the nine months ended September 30, 2026, under the Plans is summarized below:

10. 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 and nine months ended September 30, 2026, and 2025.
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 probable 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.
11. Income Taxes
For the three and nine months ended September 30, 2026, the Company recorded an income tax provision of $11.6 million and $14.2 million, respectively. The Company’s effective tax rate for the three and nine months ended September 30, 2026, was (43.4)% and (130.6)%, respectively, compared to 12.9% and 17.7%, respectively, for the corresponding period in the prior year. The difference in effective tax rates between the periods was primarily due to the Polymem divestiture and intangible asset impairment charges.
12. (Loss) Earnings Per Share
The Company reports earnings or loss per share in accordance with ASC 260, “Earnings Per Share,” which establishes standards for computing and presenting earnings or loss per share. Basic earnings or loss per share is computed by dividing net income or loss available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings or loss per share is computed by dividing net income or loss available to common shareholders by the weighted-average number of common shares and dilutive common share equivalents outstanding during the period. Potential common share equivalents consist of restricted stock awards (including performance stock units) and the incremental common shares issuable upon the exercise of stock options, stock issuable upon conversion of convertible debt securities and certain contingent consideration earnouts. The dilutive effects of restricted stock awards and stock options are reflected in diluted earnings or loss per share by application of the treasury stock method. The dilutive effect of shares issuable upon conversion of the convertible debt securities are included in the calculation of diluted earnings or loss per share under the if-converted method, while contingent consideration is considered dilutive when the conditions for issuance are met at the end of the reporting period.
In periods where the Company is in a net loss position, diluted loss per share is the same as basic loss per share, as the effects of common stock equivalents outstanding, shares issuable upon conversion of convertible debt securities and shares issuable from certain contingent consideration earnouts, are antidilutive and therefore excluded from the calculation of diluted loss per share.

13. Segment Reporting
The Company operates under one reportable segment. The Company’s chief operating decision maker (“CODM”), is the Chief Executive Officer (“CEO”). The Company views its operations, makes decisions regarding how to allocate resources and manages its business as one reportable segment and one reporting unit. The CODM reviews financial information presented on a consolidated basis for purposes of allocating resources and assessing financial performance. Net income or net loss as reported on the consolidated statement of comprehensive income or loss is the measure of segment profit or loss used by the CODM in allocating resources and assessing performance. Total assets for the operating segment is the amount presented on the condensed consolidated balance sheets.

Concentrations of Credit Risk and Significant Customers
Financial instruments that subject the Company to significant concentrations of credit risk primarily consist of cash and cash equivalents, marketable securities and accounts receivable. The Company's investment policy requires that it only invest in highly-rated securities and limits its exposure to any single-issuer to mitigate the risk of credit loss.
The Company’s expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers' trade accounts receivable. The Company’s expected loss allowance and changes in the allowance period over period have not been historically material. Concentration of credit risk with respect to accounts receivable is limited to customers to whom the Company makes significant sales. To control credit risk, the Company performs regular credit evaluations of its customers’ financial condition.
There was no revenue from a specific customer that represented 10% or more of the Company's total revenue for the three and nine months ended September 30, 2026, or 2025.
One customer represented 10% of the Company’s total trade accounts receivable balance at September 30, 2026, and no customer represented 10% or more of the Company's total trade accounts receivable balance at December 31, 2025.
14. Subsequent Events
On October 29, 2026, the Company entered into privately negotiated exchange and subscription agreements with certain holders of its outstanding 1.00% Convertible Senior Notes due 2028 and certain new investors. Pursuant to the agreements, the Company expects to issue $1.0 billion aggregate principal amount of 0.25% Convertible Senior Notes due 2031 (the “New Notes”). Approximately $541.4 million principal amount of the New Notes will be issued in exchange for approximately $456.8 million principal amount of 2028 Notes (the “Exchange Transactions”) and approximately $458.6 million principal amount of the New Notes will be issued for cash (the “Subscription Transactions”, and together with the Exchange Transactions, the “Transactions”). In connection with the issuance of the New Notes, the Company intends to use approximately $120.0 million of the net proceeds from the Subscription Transactions to repurchase shares of its common stock from certain purchasers of the New Notes. The transactions are expected to close in November 2026, subject to customary closing conditions.
On October 6, 2026, the Company completed its previously announced acquisition of BioLife Solutions, Inc. (“BioLife”), a company focused on developing cell processing tools and services for the cell and gene therapy market, for approximately $1.9 billion, comprised of approximately 7.2 million shares in the Company’s common stock and approximately $564 million in cash on hand. BioLife stockholders received $11.25 in cash per BioLife share plus 0.1442 shares of the Company’s common stock per BioLife share. Following the acquisition, BioLife operates as the Company’s wholly owned subsidiary under the name “BioLife Solutions, LLC.” The Company will account for the acquisition in the fourth quarter of 2026.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Overview
Repligen and its subsidiaries, collectively doing business as Repligen Corporation (“Repligen”, “we”, “our”, or the “Company”) is a global life sciences company that develops and commercializes highly innovative bioprocessing technologies and systems that increase efficiencies and flexibility in the process of manufacturing biological drugs.
As the overall market for biologics continues to grow and expand, our customers – primarily large biopharmaceutical companies and contract development and manufacturing organizations (“CDMOs”) and other life sciences companies (integrators) – face critical production cost, capacity, quality and time pressures. Our products help enable customers to address these concerns, both accelerating development and improving yields. We are committed to inspiring advances in bioprocessing as a trusted partner in the production of critical biologic drugs – including monoclonal antibodies (“mAbs”) and mAb derivatives like antibody drug conjugates, recombinant proteins, RNA-based therapeutics and vaccines and cell and gene therapies – that are improving human health worldwide. For more information regarding our business, products and acquisitions, see Part I, Item 1, “Business”, included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which was filed with the Securities and Exchange Commission (“SEC”) on February 26, 2026 (“Form 10-K”).
We currently operate as one bioprocessing business, with a comprehensive suite of products to serve both upstream and downstream processes in biological drug manufacturing. Building on over 40 years of industry expertise, we have developed a broad and diversified product portfolio that reflects our passion for innovation and the customer-first culture that drives our entire organization. We continue to capitalize on opportunities to maximize the value of our product platform through both organic growth initiatives (internal innovation and commercial leverage) and targeted acquisitions.
Macroeconomic Trends
As a result of our global presence, a significant portion of our revenue and expenses is denominated in currencies other than the United States (“U.S.”) dollar. We are therefore subject to non-U.S. exchange exposure. Exchange rates can be volatile and a substantial weakening or strengthening of foreign currencies against the U.S. dollar could increase or reduce our revenue and gross profit margin and impact the comparability of results from period to period.
We have experienced, and expect to continue to experience, cost inflation, primarily in raw materials and other supply chain costs, as a result of global macroeconomic trends, including global geopolitical conflicts and labor shortages. Actions taken to mitigate supply chain disruptions and inflation, including price increases and productivity improvements, have generally been successful in offsetting the impact of these trends.
On February 20, 2026, the U.S. Supreme Court rendered a decision invalidating tariffs imposed by the Trump administration under the International Emergency Economic Powers Act (“IEEPA”). This decision introduces uncertainty regarding future trade policy actions and could impact our cost structure and supply-chain planning. We will continue to monitor the effects of tariffs implemented by the Trump administration and the potential imposition of modified or additional tariffs.
Acquisitions
On October 6, 2026, we completed our previously announced acquisition of BioLife Solutions, Inc. (“BioLife”), a company focused on developing cell processing tools and services for the cell and gene therapy market, for approximately $1.9 billion, comprised of approximately 7.2 million shares in our common stock and approximately $564 million in cash on hand. Following the acquisition, BioLife operates as our wholly owned subsidiary under the name “BioLife Solutions, LLC.” BioLife brings a differentiated portfolio of products including a market-leading bio- preservation media platform and other cell processing tools, expanding our presence in the cell therapy market. We will account for the acquisition in the fourth quarter of 2026. See Note 14, “Subsequent Events,” included in Part I, Item 1, “Financial Statements,” in this Quarterly Report on Form 10-Q.
On March 4, 2025, we completed our acquisition of 908 Devices Inc.’s (“908 Devices”) desktop portfolio of four devices for bioprocessing process analytical technology applications (“PAT Portfolio,” together with 908 Devices, the “908 Devices PAT Portfolio”). In connection with the transaction, we also acquired facilities, employees, equipment and lease obligations for facilities in North Carolina and Braunschweig, Germany as well as certain working capital balances related to the PAT Portfolio. The addition of these desktop assets complements and strengthens our differentiated PAT Portfolio that provides its biopharmaceutical and CDMO customers with actionable insights to optimize development processes and improve manufacturing efficiencies.

Cost of goods sold
During the three and nine months ended September 30, 2026, cost of goods sold increased by $10.0 million, or 11.4%, and $22.9 million, or 9.0%, respectively, compared to the same period in 2025. Gross margin decreased to 53.0% for the three months ended September 30, 2026, compared to 53.2% for the same period in 2025. Gross margin increased to 54.2% for the nine months ended September 30, 2026, compared to 52.7% for the same period in 2025. The increase in cost of goods sold is primarily driven by higher product sales compared to the same periods in 2025, partially offset by improved leverage on indirect labor and overhead. The decrease in gross margin during the three months ended September 30, 2026, is primarily driven by unfavorable product mix, partially offset by improved leverage on indirect labor and overhead. The increase in gross margin during the nine months ended September 30, 2026, is driven by favorable product mix and improved leverage on indirect labor and overhead.
Research and development expenses
Research and development (“R&D”) expenses are related to the development of products supporting bioprocessing operations. The expenses include personnel compensation, supplies and other research expenses. Due to the fact that these various programs share personnel and fixed costs, we have not provided historical costs incurred by project.
R&D expenses increased by $0.3 million, or 1.8%, and $3.1 million, or 7.6%, respectively, during the three and nine months ended September 30, 2026, as compared to the same periods in 2025. The primary driver of the increase in R&D costs during the three and nine months ended September 30, 2026, is incremental R&D personnel expenses from the 908 Devices PAT Portfolio acquisition.
Selling, general and administrative expenses
Selling, general and administrative (“SG&A”) expenses include the costs associated with selling our commercial products and costs required to support our marketing efforts. It also includes legal, accounting, patent, shareholder services, amortization of intangible assets and other administrative functions.
SG&A costs increased by $9.9 million, or 13.5%, and $21.5 million, or 10.0%, respectively, during the three and nine months ended September 30, 2026, as compared to the same periods in 2025. The primary drivers of the increase in SG&A costs is investment in personnel costs to support growth, driven by corporate reorganization efforts, and increased professional services fees, driven by recent acquisition activities.
Restructuring activities and other charges
Restructuring activities and other charges increased by $2.0 million, or 100%, and $2.0 million, or 49.5%, respectively, during the three and nine months ended September 30, 2026, as compared to the same periods in 2025.
During the first quarter of 2026, we initiated a series of restructuring activities to simplify the global manufacturing footprint of the organization and align our workforce to support long-term company growth. These activities will include a series of site optimization phases with the purpose of improving operating efficiency and are expected to be completed by the end of 2027.

Table of Contents
Prior period costs consist of restructuring activities we started in 2023 to simplify and streamline our organization and strengthen the overall effectiveness of operations. The activities continued into 2024 and 2025 and included consolidating a portion of the manufacturing operations between certain U.S. locations, writing-off abandoned equipment with the rationalization of excess production line capacity and discontinuing the sale of certain product SKUs. We do not expect further costs related to these actions.
Intangible asset impairment charges
Intangible asset impairment charges increased by $41.2 million, or 100%, during the three and nine months ended September 30, 2026, as compared to the same periods in 2025.
During the three months ended September 30, 2026, we identified an impairment indicator related to certain definite-lived intangible assets, specific to an intellectual property license agreement, and performed an impairment analysis. Following this analysis, these definite-lived intangible assets were determined to be a separate asset group. As a result, we determined the developed-technology intangible assets related to the intellectual property license agreement were impaired and recorded a $41.2 million impairment charge, included within intangible asset impairment charges on the condensed consolidated statements of comprehensive income or loss.
Change in fair value of contingent consideration
Change in fair value of contingent consideration represents the change in fair value of the obligation included in current and noncurrent contingent consideration on the consolidated balance sheets as of the end of each period. Remeasurement of the contingent consideration obligation is done each quarter and the carrying value of the obligation is adjusted to the current fair value through our condensed consolidated statements of comprehensive income or loss.

Investment income
Investment income includes income earned on cash, cash equivalents and marketable securities. Our investment income increased by $0.1 million and decreased by $1.0 million for the three and nine months ended September 30, 2026, respectively, as compared to the same periods in 2025 due to changes in interest rates. We expect investment income to vary based on changes in the amount of funds invested and fluctuation of interest rates.
Interest expense
Interest expense increased by $0.3 million and $0.9 million for the three and nine months ended September 30, 2026, respectively, as compared to the same periods in 2025. Interest expense includes contractual coupon interest on the 2023 Notes, as defined below, and the associated accretion of the discount. The discount is being accreted into interest expense using the effective interest method over the term of the 2023 Notes. See Note 8, “Convertible Senior Notes” to our condensed consolidated financial statements included in this report for more information.
Amortization of debt issuance costs
Transaction costs related to the issuance of the 2023 Notes, as defined below, are amortized and recorded within amortization of debt issuance costs on the condensed consolidated statements of comprehensive income or loss.
Loss on sale of business
On March 30, 2026, we completed the sale of Polymem S.A.S. (“Polymem”) for total consideration of $3.6 million, net of cash divested. We recognized a net loss on the sale of business of $13.7 million during the nine months ended September 30, 2026.

Other income (expense), net increased by $2.7 million and decreased by $1.5 million for the three and nine months ended September 30, 2026, respectively, as compared to the same periods in 2025. Other income (expense), net primarily includes the changes in foreign currency transaction gains and losses, revaluation impact of intercompany loans with subsidiaries and unrealized and realized impacts of foreign exchange forward contracts.
Income tax provision
Income tax provision for the three and nine months ended September 30, 2026, and 2025 was as follows:

Effective tax rate(43.4)%12.9 %(130.6)%17.7 %
For the three and nine months ended September 30, 2026, we recorded an income tax provision of $11.6 million and $14.2 million, respectively. The effective tax rate was (43.4)% and (130.6)% for the three and nine months ended September 30, 2026, respectively, and is based upon the estimated income for the year ending December 31, 2026, and the composition of income in different jurisdictions.
The difference in effective tax rates between the periods was primarily due to the Polymem divestiture and intangible asset impairment charges. Our effective tax rate for the three months ended September 30, 2026, was lower than the U.S. statutory rate of 21% primarily due to additional discrete expense related to the Polymem divestiture and intangible asset impairment charges. Our effective tax rate for the nine months ended September 30, 2026, was lower than the U.S. statutory rate of 21% primarily due to the Polymem divestiture and intangible asset impairment charges.
Liquidity and Capital Resources
We have financed our operations primarily through revenues derived from product sales and the issuance of notes and public offerings. Our revenue for the foreseeable future will primarily be limited to our bioprocessing product revenue. The following table shows sources of liquidity for the periods presented:

Total liquidity$862,979 $767,628 
On December 14, 2023, we issued $600.0 million aggregate principal amount of 1.00% Convertible Senior Notes due 2028 (the “2023 Notes”) in a private placement pursuant to separate, privately negotiated exchange and subscription agreements (the “Exchange and Subscription Agreements”) with a limited number of holders of the 0.375% Convertible Notes due 2024 (the “2019 Notes”) and certain other qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (“Securities Act”).
The 2023 Notes are senior, unsecured obligations of the Company, and bear interest at a rate of 1.00% per year and have an effective interest rate of 4.39%. Interest is payable semi-annually in arrears on each of June 15 and December 15, which commenced on June 15, 2024. The 2023 Notes will mature on December 15, 2028, unless earlier redeemed, repurchased or converted.
The conditional conversion features of the 2023 Notes were not triggered during the calendar quarter ended September 30, 2026, therefore, the 2023 Notes are not convertible during the calendar quarter ended December 31, 2026, pursuant to the applicable last reported sales price conditions, as stated in the indenture governing the 2023 Notes.

Operating activities
For the nine months ended September 30, 2026, our operating activities provided cash of $104.2 million reflecting net loss of $25.1 million and non-cash charges totaling $164.2 million primarily related to depreciation and intangible amortization, intangible asset impairment charges, loss on sale of Polymem, stock-based compensation, operating lease right of use asset amortization and amortization of debt discount and issuance costs, partially offset by changes in deferred income taxes, net and other non-cash items.
The non-cash charges were partially offset by unfavorable changes in working capital of $35.0 million. This is primarily driven by increases in inventories of $16.1 million, increases in prepaid expenses and other current assets of $3.7 million, decreases in operating lease liabilities of $18.8 million, primarily due to normal course rent payments and net decreases in accounts payable and accrued liabilities of $3.0 million due to timing of payments to vendors and compensation. These are partially offset by decreases in accounts receivable of $3.4 million due to timing of sales and receipts from customers. The remaining cash provided by operating activities resulted from net favorable changes in various other working capital accounts.
For the nine months ended September 30, 2025, our operating activities provided cash of $91.7 million reflecting net income of $35.6 million and non-cash charges totaling $82.6 million primarily related to depreciation and intangible amortization, stock-based compensation, operating lease right of use asset amortization and amortization of debt discount and issuance costs, partially offset by net unrealized foreign exchange gains, changes in the fair value of contingent consideration and deferred income taxes, net. The non-cash charges were partially offset by unfavorable changes in working capital of $26.5 million. This is primarily driven by decreases in operating lease liabilities of $12.1 million, primarily due to normal course rent payments, increases in accounts receivable of $7.3 million due to timing of sales and receipts from customers, increases in prepaid expenses and other current assets of $5.5 million, and increases in inventories of $5.3 million. These are partially offset by net increases in accounts payable and accrued liabilities of $4.5 million due to timing of payments to vendors. The remaining cash provided by operating activities resulted from net unfavorable changes in various other working capital accounts.
Investing activities
Our investing activities provided cash of $57.9 million during the nine months ended September 30, 2026, which was primarily driven by increased maturities and sales of marketable securities of $271.1 million, compared to purchases of marketable securities of $200.5 million and proceeds received, net of cash divested from our sale of Polymem of $3.6 million. These are partially offset by capital expenditures of $16.3 million, inclusive of $1.3 million of capitalized costs related to our internal-use software.
Our investing activities consumed $89.7 million of cash during the nine months ended September 30, 2025, which was primarily driven by the acquisition of the 908 Devices PAT Portfolio, net of cash acquired, of $70.0 million. Capital expenditures during the nine months ended September 30, 2025, consumed $17.4 million, including $2.1 million of capitalized costs related to our internal-use software.
Financing activities
Our financing activities provided cash of $2.9 million for the nine months ended September 30, 2026, which was primarily driven by proceeds received from exercise of stock options of $15.9 million, partially offset by cash disbursed related to the tax withholding obligation on vesting of restricted stock units of $7.8 million and cash payments for a portion of the contingent earnout obligation related to the acquisition of Tantti of $5.2 million.
Our financing activities consumed $15.4 million of cash for the nine months ended September 30, 2025, which was driven by $8.0 million of cash disbursed related to the tax withholding obligation on vesting of restricted stock units and $9.5

million to settle the cash portions of the contingent consideration earnout obligations related to acquisitions from previous years. These cash outflows are partially offset by proceeds received from stock option exercises of $2.1 million.
Future capital requirements
Our future capital requirements will depend on many factors, including the following:
•the expansion of our bioprocessing business;
•the ability to sustain sales and profits of our bioprocessing products and successfully integrate them into our business;
•our ability to acquire additional bioprocessing products;
•the scope of and progress made in our R&D activities;
•the scope of investment in our intellectual property portfolio;
•contingent consideration earnout payments resulting from our acquisitions;
•conversion or refinancing efforts related to the 2023 Notes or other forms of indebtedness;
•the extent of any share repurchase activity;
•the success of any proposed financing efforts;
•general economic and capital markets;
•the impact of inflation on our operations, including our expenditures on raw materials and freight charges;
•fluctuations in foreign currency exchange rates; and
•costs associated with our ability to comply with, emerging environmental, social and governance standards.
On October 29, 2026, we entered into privately negotiated exchange and subscription agreements with certain holders of our outstanding 1.00% Convertible Senior Notes due 2028 and certain new investors. Pursuant to the agreements, we expect to issue $1.0 billion aggregate principal amount of 0.25% Convertible Senior Notes due 2031 (the “New Notes”). Approximately $541.4 million principal amount of the New Notes will be issued in exchange for approximately $456.8 million principal amount of 2028 Notes (the “Exchange Transactions”) and approximately $458.6 million principal amount of the New Notes will be issued for cash (the “Subscription Transactions”, and together with the Exchange Transactions, the “Transactions”). In connection with the issuance of the New Notes, we intend to use approximately $120.0 million of the net proceeds from the Subscription Transactions to repurchase shares of its common stock from certain purchasers of the New Notes. The transactions are expected to close in November 2026, subject to customary closing conditions.
On October 6, 2026, we completed the acquisition of BioLife pursuant to the Merger Agreement entered into on July 21, 2026, for approximately $1.9 billion, comprised of approximately 7.2 million shares in our common stock and approximately $564 million in cash. We funded the cash portion of the consideration with cash and cash equivalents on hand.
Aside from items discussed herein, there have been no other material changes to our future capital requirements or contractual obligations disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025, which was filed with the SEC on February 26, 2026.
Absent acquisitions of additional businesses, products, product candidates or intellectual property not reflected herein, we believe our current liquidity and future cash flow from operations are adequate to meet our cash needs for at least one year from this Quarterly Report on 10-Q. We expect operating expenses in 2026 to increase as we continue to expand our bioprocessing business. We expect to incur continued spending related to the development and expansion of our bioprocessing product lines and expansion of our commercial capabilities for the foreseeable future. Our future capital requirements may include, but are not limited to, purchases of property, plant and equipment, the acquisition of additional bioprocessing products and technologies to complement our existing manufacturing capabilities, continued investment in our intellectual property portfolio and financing activities to service our outstanding convertible notes.
We plan to continue to invest in our bioprocessing business and in key R&D activities associated with the development of new bioprocessing products. We actively evaluate various strategic transactions on an ongoing basis, including licensing, acquiring or investing in products, technologies or businesses that would complement our existing portfolio. We continue to seek to acquire or invest in such potential assets that may offer us the best opportunity to create value for our shareholders. In order to do so, we may need to seek additional financing to fund these investments. If our available cash balances and anticipated cash flow from operations are insufficient to satisfy our liquidity requirements, for example, due to acquisition-related financing needs, servicing of our outstanding indebtedness or lower demand for our products, among
28
Table of Contents
potential other events, we may seek to sell common or preferred equity or convertible debt securities, enter into a credit facility or another form of third-party funding, or seek other debt funding. The sale of equity and convertible debt securities may result in dilution to our shareholders, and those securities may have rights senior to those of our common shares. If we raise additional funds through the issuance of preferred stock, convertible debt securities or other debt financing, these securities or other debt could contain covenants that would restrict our operations. Any other third-party funding arrangement could require us to relinquish valuable rights. We may require additional capital beyond our currently anticipated amounts. Additional capital may not be available on reasonable terms, if at all.
Our future capital requirements and the adequacy of available funds will depend on many factors, including those described herein and in our other filings with the SEC, including those set forth in Part I, Item 1A, Risk Factors in our 10-K for the year ended December 31, 2025.
Off-balance sheet arrangements
We do not have any special purpose entities or off-balance sheet financing arrangements.
Effect of exchange rate changes on cash, cash equivalents and restricted cash
The effect of exchange rate changes on cash during the three and nine months ended September 30, 2026, is a result of using multiple currencies across the group, with the Euro and Swedish Krona being significant currencies for the group outside of the US Dollar.
Net Operating Loss Carryforwards
At December 31, 2025, we had federal net operating loss carryforwards of $7.5 million, state net operating loss carryforwards of $15 million, and foreign net operating loss carryforwards of $27.4 million. The federal net operating loss carryforwards have unlimited carryforward periods and do not expire. The state net operating loss carryforwards will expire at various dates through 2045. Approximately $5.7 million of the foreign net operating loss carryforwards have unlimited carryforward periods and do not expire, while $21.7 million of the foreign net operating loss carryforwards will expire at various dates through 2034. We had federal and state business tax credit carryforwards of $7.1 million available to reduce future federal and state income taxes. The business tax credit carryforwards will expire at various dates through 2045. Net operating loss carryforwards and available tax credits are subject to review and possible adjustment by the Internal Revenue Service, state and foreign jurisdictions and may be limited in the event of certain changes in the ownership interest of significant stockholders.
Effects of Inflation
Our assets are primarily monetary, consisting mainly of cash and cash equivalents. Because of their liquidity, these assets are not directly affected by inflation. Since we intend to retain and continue to use our equipment, furniture, fixtures and office equipment, computer hardware and software and leasehold improvements, we believe that the incremental inflation related to replacement costs of such items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase our level of expenses and the rate at which we use our resources.

We assume no obligation to update any forward-looking information contained in this Form 10-Q, except as required by law.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
There have been no material changes to our market risk exposures since December 31, 2025. For information regarding our exposure to certain market risks, see “Quantitative and Qualitative Disclosures About Market Risk”, included in Part II, Item 7A, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which was filed with the Securities and Exchange Commission on February 26, 2026.
ITEM 4. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
The Company’s management is responsible for establishing and maintaining adequate disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934 (“Exchange Act”)). Disclosure controls and procedures are those controls and procedures that are designed to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commissions’ rules and forms, and that such information is accumulated and communicated to the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.
Under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, the Company carried out an evaluation as of September 30, 2026, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rules 13a-15(b) and 15d-15(b). Based on such evaluation, the principal executive officer and principal financial officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were not effective because of the previously reported material weaknesses in our internal control over financial reporting, which are described in Part II, Item 9A, “Controls and Procedures” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, which was filed with the Securities and Exchange Commission on February 26, 2026 (“Form 10-K”). Notwithstanding the material weaknesses, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q are fairly stated in all material respects in accordance with generally accepted accounting principles in the United States for each of the periods presented.
Material Weaknesses in Internal Control Over Financial Reporting
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis. As previously disclosed in the Form 10-K, the Company identified the following material weaknesses in internal control over financial reporting:
•Management did not maintain effective information technology (“IT”) general controls for information systems that are relevant to the preparation of our financial statements. Specifically, we did not maintain logical access controls and program change management controls to ensure that access to programs and data are appropriately restricted and program and data changes are identified, tested, authorized and implemented appropriately. As a
30
Table of Contents
result, automated and business process controls that rely on information from the systems were also deemed ineffective because they could have been adversely affected.
•Irrespective of the effects of the IT general controls deficiencies, management did not perform certain business process-level controls related to inventory valuation and the financial statement close process either in a timely manner or with an appropriate precision threshold.
As of September 30, 2026, the Company has not remediated these material weaknesses. In connection with the remediation plan previously disclosed in the Form 10-K, the Company performed remediation activities during the nine months ended September 30, 2026, as detailed below.
Remediation Plans
IT General Controls - During the nine months ended September 30, 2026, our remediation activities included the following with respect to IT general controls:
•Continued execution of controls that we worked to improve during fiscal year 2025 that did not have a sufficient period of time to demonstrate operating effectiveness as of December 31, 2025;
•Engaging third-party experts to assist in certain aspects of the remediation plan;
•Redesigning certain existing controls with additional attributes to mitigate the presumed IT risk relevant to the control;
•Evaluating, enhancing, and adding personnel in the IT organization with a focus on the requisite experience in the areas of internal control compliance; and
•Assessing and identifying areas within logical access where supplemental tools can be implemented to enhance role security and logical access controls compliance.
Business process-level controls related to inventory valuation and the financial statement close process - During the nine months ended September 30, 2026, our remediation activities included the following with respect to certain business process-level controls related to inventory valuation and the financial statement close process:
•Continued execution of controls that we worked to improve during fiscal year 2025 that did not have a sufficient period of time to demonstrate operating effectiveness as of December 31, 2025;
•Redesigning and executing enhanced controls related to inventory valuation;
•Engaging third-party experts to assist in certain aspects of the remediation plan;
•Initiating the implementation of software tools in fiscal year 2026 to support control monitoring activities and the retention of control documentation; and
•Provided ongoing training related to internal control over financial reporting for control owners.
We believe we are making progress toward achieving effectiveness of our internal control over financial reporting. The actions that we are taking are subject to ongoing management review and Audit Committee oversight. We will not be able to conclude whether the steps we are taking will fully remediate the material weaknesses in our internal control over financial reporting until we have completed our remediation efforts and subsequently evaluated their design and effectiveness over a sufficient period of time, and management concludes, through testing, that these controls are operating effectively. We may also conclude that additional measures are required to remediate the material weaknesses in our internal control over financial reporting.
Changes in Internal Control
Except for the material weaknesses described above, there have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rule 13a-15 or Rule 15d-15 that occurred in the three months ended September 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. We are not currently aware of any such proceedings or claims that we believe will have, individually or in the aggregate, a material
31
Table of Contents
adverse effect on our business, financial condition or results of operations, nor are we aware of any governmental proceedings involving potential monetary sanctions of $0.3 million or more.
ITEM 1A. RISK FACTORS
The matters discussed in this Quarterly Report on Form 10-Q include forward-looking statements that involve risks or uncertainties. These statements are neither promises nor guarantees, but are based on various assumptions by management regarding future circumstances, over many of which Repligen has little or no control. A number of important risks and uncertainties, including those identified under the caption “Risk Factors” in Part I, Item 1A of our Form 10-K for the period ended December 31, 2025, and in subsequent filings, could cause our actual results to differ materially from those in the forward-looking statements. The information presented below supplements the risks and uncertainties identified under the caption “Risk Factors” in Part I, Item 1A of our Form 10-K for the period ended December 31, 2025.
We may be unable to successfully and efficiently integrate BioLife’s business into the Repligen enterprise, which could adversely affect our business, financial condition and results of operations.
Our ability to realize the anticipated benefits of the acquisition of BioLife depends on the successful and efficient integration of BioLife’s business into our existing business. The integration process may require significant management attention and resources and could result in unforeseen difficulties, delays or costs. We may also be unable to retain key employees or realize the anticipated cost savings or synergies from the acquisition. Such integration efforts, whether successful or not, could divert BioLife and Repligen management’s attention from ongoing business operations and other opportunities and could give rise to adverse reactions or changes to business or employee relationships. If we are unable to successfully integrate BioLife’s operations and realize the anticipated benefits of the acquisition, our business, financial condition and results of operations could be materially adversely affected.
Our assumptions around the size and trajectory of the cell therapy market and BioLife’s market position may prove to be incorrect, which, along with other risks and uncertainties related to the BioLife transaction, could materially and adversely affect our business and financial results.
Other risks and uncertainties related to the BioLife transaction that could materially and adversely affect our business and financial results include the risk that the parties have overestimated the size or trajectory of the cell therapy market and BioLife’s market position, as well as the possibility that the anticipated financial impact and revenue growth of the transaction will not be realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where we and BioLife do business; the outcome of any legal proceedings that may be instituted against us or BioLife in connection with the transaction or otherwise; and the potential for increased regulatory scrutiny and the impact on the clinical pipeline, global approvals and expanded indications.
ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
None.
ITEM 3. DEFAULTS UPON SENIOR SECURITIES
None.
ITEM 4. MINE SAFETY DISCLOSURES
Not applicable.
ITEM 5. OTHER INFORMATION
(a)None.
(b)None.
(c)Rule 10b5-1 Trading Plans
None of our directors or officers adopted, modified or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement” during the three months ended September 30, 2026.
