NOTES TO CONSOLIDATE D FINANCIAL STATEMENTS

(Unaudited)

1.
Summary of Significant Accounting Policies

Basis of Presentation

The 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 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 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, 2021, which was filed with the SEC on February 17, 2022 (“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 period. The business and economic uncertainty resulting from the novel coronavirus pandemic (“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 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 Limited and its subsidiaries, Polymem S.A. (“Polymem”), Avitide LLC, Newton T&M Corp. ("NTM"), Bio-Flex Solutions, L.L.C. ("BioFlex") and Repligen Singapore Pte. Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation.

Except for the change in the Company's policy on Convertible Senior Notes as required by Accounting Standards Update ("ASU" or "ASUs") 2020-06 and discussed in Note 7, "Convertible Senior Notes," to these 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 management, the accompanying unaudited consolidated financial statements include all adjustments, consisting of only normal, recurring adjustments necessary for a fair presentation of the financial position, results of operations and cash flows. 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 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 consolidated financial position or results of operations. Recently issued ASUs that we feel may be applicable to the Company are as follows:

Recently Issued Accounting Standards Updates – Adopted During the Fiscal Year

Effective January 1, 2022, the Company adopted ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40)” using the modified retrospective method of adoption. ASU 2020-06 simplifies the accounting for convertible debt instruments and convertible preferred stock by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. Consequently, a convertible instrument is now accounted for as a single liability measured at its amortized cost as long as no other features of such convertible instrument require bifurcation and recognition as derivatives. By removing those separation models, the interest rate of convertible debt instruments will typically be closer to the coupon interest rate when

7

applying the guidance in Topic 835, “Interest.” The Company now accounts for its 0.375% convertible senior notes due July 15, 2024 (the "2019 Notes") as a single liability measured at amortized cost. As a result, the adoption of ASU 2020-06 had a material impact on the Company's consolidated financial statements, resulting in adjustments of $39.1 million, $17.3 million and $27.6 million to the opening balances of additional paid-in capital, retained earnings and Convertible Senior Notes, net, respectively, on the Company's consolidated balance sheet as of January 1, 2022. Additionally, due to the adoption of ASU 2020-06, the Company reversed the remaining balance of the deferred tax liability of $6.4 million, which was initially recorded in connection with the 2019 Notes. See Note 7, “Convertible Senior Notes,” for more information, including our modified disclosures as required by ASU 2020-06 upon adoption.

Recently Issued Accounting Standard Updates – Not Yet Adopted

In March 2022, the Financial Accounting Standards Board issued ASU 2022-02, “Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 eliminates the accounting guidance for Troubled Debt Restructurings by creditors that have adopted ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” while enhancing disclosure requirements for certain loan refinancing and restructurings made to borrowers experiencing financial difficulty. Additionally, ASU 2022-02 adds the requirement for companies to disclose current period write-offs by year of origination for financing receivables. ASU 2022-02 will become effective for the Company on January 1, 2023. Early adoption is permitted if an entity has adopted ASU 2016-13. The Company is currently evaluating the timing and impact of the adoption of ASU 2022-02 on the Company’s consolidated financial statements and disclosures.

2.
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 in markets that are not active and models for which all significant inputs are observable, either directly or indirectly.
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.

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 June 30, 2022 and December 31, 2021 (amounts in thousands):

|  | As of June 30, 2022 |
|  | Level 1 |  |  | Level 2 |  |  | Level 3 |  |  | Total |

Cash and cash equivalents

As of June 30, 2022 and December 31, 2021, cash and cash equivalents on the Company's consolidated balance sheets included $389.4 million and $460.9 million, respectively, in money market accounts. These funds are valued on a recurring basis using Level 1 inputs.

Contingent Consideration – Earnout

On September 20, 2021, the Company completed the acquisition of Avitide, Inc. ("Avitide") (the "Avitide Acquisition"), a privately-held affinity ligand discovery and development company headquartered in Lebanon, New Hampshire. The transaction consisted of upfront payments of $150.0 million, comprised of cash and the Company's common stock, and up to an additional $125.0 million (undiscounted) in contingent consideration for performance-based earnout payments made equally in cash and the Company's common stock over a three-year performance period beginning January 1, 2022 and ending December 31, 2024. See Note 3, "Acquisitions" below for additional information.

During 2022, there was a shift in revenue and volume projections, due to the expected timing of achievement over the three-year performance period, and an increase in risk-free interest rates that are used to calculate the discount rate, that resulted in a material change in amounts reported as of June 30, 2022. A reconciliation of the change in the fair value of contingent consideration - earnout is included in the following table (amounts in thousands):

Balance as of December 31, 2021 |  | $ | 94,238 |
Contingent consideration earnouts |  |  | (9,295 | )
Balance as of June 30, 2022 |  | $ | 84,943 |

The recurring Level 3 fair value measurement of our contingent consideration earnout that we expect to be required to settle include the following significant unobservable inputs (amounts in thousands, except percent data):

Contingent Consideration Earnout |  | Fair Value as of June 30, 2022 |  | Valuation Technique |  | Unobservable Input |  | Range |  | Weighted Average(1)
|  |  |  |  |  |  | Probability of |  |  |  |

|  |  |  |  |  |  | Earnout Discount Rate |  | 4.5%-5.8% |  | 5.1%

(1)
Unobservable inputs were weighted by the relative fair value of the contingent consideration liability.

The Company estimates the fair value of the contingent consideration earnouts at each subsequent reporting period using a Monte Carlo simulation. Changes in the projected performance of the acquired business could result in a higher or lower contingent consideration obligation in the future.

Fair Value Measured on a Nonrecurring Basis

During the three and six months ended June 30, 2022, there were no re-measurements to fair value of financial assets and liabilities that are measured at fair value on a nonrecurring basis.

Convertible Senior Notes

In July 2019, the Company issued $287.5 million aggregate principal amount of the 2019 Notes. Interest is payable semi-annually in arrears on January 15 and July 15 of each year. The 2019 Notes will mature on July 15, 2024, unless earlier converted or repurchased in accordance with their terms. At June 30, 2022 and December 31, 2021, the carrying value of the 2019 Notes was $283.7 million and $255.3 million, respectively, net of unamortized discount and issuance costs, and the fair value of the 2019 Notes was $432.3 million and $678.5 million, respectively. The fair value of the 2019 Notes is a Level 1 valuation and was determined based on the most recent trade activity of the 2019 Notes as of June 30, 2022. The 2019 Notes are discussed in more detail in Note 7, “Convertible Senior Notes” to this report.

Acquisitions

2021 Acquisitions

Bio-Flex Solutions L.L.C. and Newton T&M Corp.

On November 29, 2021, the Company entered into an Equity Purchase Agreement with BioFlex, NTM and each of Ralph Meola and Jason Nisler (the "Equity Purchase Agreement"), to acquire 100% of the outstanding securities of BioFlex and NTM (collectively, the “NTM Acquisition”). The transaction closed on December 16, 2021.

NTM, which is headquartered in Newton, New Jersey, is the parent company of BioFlex and focuses on manufacturing of products, while BioFlex, also headquartered in Newton, New Jersey, commercializes branded products to biotech customers. The NTM Acquisition complements and expands the Company's filtration offering paths as the industry migrates to single-use flow paths solutions for monoclonal antibody, vaccine and cell and gene therapy ("C&GT") applications, with a focus on single-use fluid management components, including single-use clamps, adapters, end caps and hose assemblies. The NTM Acquisition streamlines and increases control over many components in the Company's single-use supply chain which ultimately should drive reduced lead-times for Repligen customers in the coming years.

Consideration Transferred

10

The NTM Acquisition was accounted for as a purchase of businesses under ASC 805, “Business Combinations,” and the Company engaged a third-party valuation firm to assist with the valuation of the business acquired. Under the terms of the Equity Purchase Agreement, all outstanding shares of capital stock of BioFlex were acquired for consideration with a value totaling $31.6 million, which includes $3.0 million deposited into an escrow against which the Company may make claims for indemnification.

Under the acquisition method of accounting, the assets acquired and liabilities assumed of BioFlex were recorded as of the acquisition date, at their respective fair values, and consolidated with those of the Company. The fair value of the net assets acquired is estimated to be $4.6 million, the fair value of the intangible assets acquired is estimated to be $17.2 million and the residual goodwill is estimated to be $9.8 million. The estimated consideration and preliminary purchase price information has been prepared using a preliminary valuation. Acquisition-related costs are not included as a component of consideration transferred but are expensed in the periods in which costs are incurred. The Company has incurred $1.9 million of transaction and integration costs associated with the NTM Acquisition from the date of acquisition to June 30, 2022, with $0.7 million and $1.6 million of transaction and integration costs incurred during the three and six months ended June 30, 2022, respectively. The transaction costs are included in operating expenses in the consolidated statements of comprehensive income for the periods ended June 30, 2022.

The preparation of the valuation required the use of significant assumptions and estimates. Critical estimates included, but were not limited to, future expected cash flows, including projected revenues and expenses and the applicable discount rates. These estimates were based on assumptions that the Company believes to be reasonable. However, actual results may differ from these estimates.

Fair Value of Net Assets Acquired

The preliminary allocation of purchase price is based on the fair value of assets acquired and liabilities assumed as of the acquisition date, based on the preliminary valuation. As of June 30, 2022, the purchase accounting for this acquisition had not yet been finalized. As additional information becomes available, the Company may further revise its preliminary purchase price allocation during the remainder of the measurement period. Any such revisions or changes may have a material impact on our accounting treatment of the NTM Acquisition. The final allocation may include changes to deferred tax assets and other assets and liabilities.

The components and estimated allocation of the purchase price consist of the following (amounts in thousands):

Cash and cash equivalents |  | $ | 2,870 |
Accounts receivable |  |  | 1,408 |
Inventory |  |  | 741 |
Prepaid expenses and other current assets |  |  | 126 |
Property and equipment |  |  | 34 |
Operating lease right of use asset |  |  | 1,034 |
Customer relationships |  |  | 13,240 |
Developed technology |  |  | 3,540 |
Trademark and tradename |  |  | 310 |
Non-competition agreements |  |  | 60 |
Goodwill |  |  | 9,804 |
Long term deferred tax asset |  |  | 111 |
Accounts payable |  |  | (224 | )
Accrued liabilities |  |  | (450 | )
Operating lease liability |  |  | (1,030 | )
Operating lease liability, long-term |  |  | (3 | )
Fair value of net assets acquired |  | $ | 31,571 |

During the first half of 2022, the Company recorded net working capital adjustments of approximately $0.4 million related to pre-acquisition liabilities, which are included in goodwill and accrued liabilities in the table above.

Acquired Goodwill

11

The goodwill of $9.8 million represents future economic benefits expected to arise from anticipated synergies from the integration of BioFlex and NTM into the Company. These synergies include certain cost savings, operating efficiencies and other strategic benefits projected to be achieved as a result of the NTM Acquisition. Substantially all of the goodwill recorded is expected to be deductible for income tax purposes.

Intangible Assets

The following table sets forth the components of the identified intangible assets associated with the NTM Acquisition and their estimated useful lives:

|  | Useful life |  | Fair Value |
|  |  |  | (Amounts in thousands) |
Customer relationships |  | 10 years |  | $ | 13,240 |
Developed technology |  | 11 years |  |  | 3,540 |
Trademark and tradename |  | 15 years |  |  | 310 |
Non-competition agreements |  | 3 years |  |  | 60 |
|  |  |  | $ | 17,150 |

Avitide, Inc.

On September 16, 2021, the Company entered into an Agreement and Plan of Merger and Reorganization (“Avitide Merger Agreement”) with Avalon Merger Sub, Inc., a Delaware corporation and a wholly owned direct subsidiary of the Company, Avalon Merger Sub LLC, a Delaware limited liability company and a wholly owned direct subsidiary of the Company, Avitide, a Delaware corporation, and Shareholder Representative Services LLC, a Colorado limited liability company, solely in its capacity as the representative, agent and attorney-in-fact of Avitide's securityholders to purchase Avitide. The transaction closed on September 20, 2021 on the terms set forth in the Avitide Merger Agreement.

Avitide, which is headquartered in Lebanon, New Hampshire, offers diverse libraries and leading technology in affinity ligand discovery and development resulting in best-in-class ligand discovery and development lead-times. The acquisition gives the Company a new platform for affinity resin development, including C&GT, and advances and expands the Company’s proteins and chromatography franchise to address the unique purification needs of gene therapies and other emerging modalities.

Consideration Transferred

The Avitide Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations,” and the Company engaged a third-party valuation firm to assist with the valuation of the business acquired. Under the terms of the Avitide Merger Agreement, all outstanding shares of capital stock of Avitide were cancelled and converted into the right to receive merger consideration with a value totaling up to $275.0 million, which consisted of upfront payments in aggregate of $150.0 million ($149.4 million, net of cash acquired) and up to an additional $125.0 million (undiscounted) in contingent consideration earnout payments if certain performance targets are achieved. Total consideration paid also included $0.8 million deposited into an escrow account against which the Company may make claims for indemnification. The Avitide Acquisition was funded through payment of $75.0 million in cash, the issuance of 271,096 unregistered shares of the Company’s common stock totaling $83.0 million and contingent consideration with a fair value of approximately $88.4 million.

Under the acquisition method of accounting, the assets acquired and liabilities assumed of Avitide were recorded as of the acquisition date, at their respective fair values, and consolidated with those of the Company. The fair value of the net assets acquired is estimated to be $2.1 million, the fair value of the intangible assets acquired is estimated to be $46.7 million and the residual goodwill is estimated to be $197.5 million. The estimated consideration and preliminary purchase price information has been prepared using a preliminary valuation. Acquisition-related costs are not included as a component of consideration transferred but are expensed in the periods in which costs are incurred. The Company has incurred $3.9 million of transaction and integration costs associated with the Avitide Acquisition from the date of acquisition to June 30, 2022, with $0.7 million and $1.3 million of transaction and integration costs incurred during the three and six months ended June 30, 2022, respectively. The transaction costs are included in operating expenses in the consolidated statements of comprehensive income for the periods ended June 30, 2022. During 2022, due to the change in market inputs used to prepare the valuation of the contingent

12

consideration obligation, the Company also recorded contingent consideration adjustments of ($6.9) million and ($9.3) million to the Company's consolidated statements of comprehensive income for the three and six months ended June 30, 2022, respectively. See Note 2, "Fair Value Measurements" for more information.

The preparation of the valuation required the use of significant assumptions and estimates. Critical estimates included, but were not limited to, future expected cash flows, including projected revenues and expenses and the applicable discount rates. These estimates were based on assumptions that the Company believes to be reasonable. However, actual results may differ from these estimates.

Total consideration transferred is as follows (amounts in thousands):

Cash consideration |  | $ | 74,962 |
Equity consideration |  |  | 82,968 |
Contingent consideration - earnout |  |  | 88,373 |
Fair value of net assets acquired |  | $ | 246,303 |

Fair Value of Net Assets Acquired

The preliminary allocation of purchase price is based on the fair value of assets acquired and liabilities assumed as of the acquisition date, based on the preliminary valuation. As of June 30, 2022, the purchase accounting for this acquisition had not yet been finalized. As additional information becomes available, the Company may further revise its preliminary purchase price allocation during the remainder of the measurement period (which will not exceed 12 months from September 20, 2021). Any such revisions or changes may have a material impact on our accounting treatment of the Avitide Acquisition. The final allocation may include changes to long-term deferred liabilities and goodwill. Upon conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments will be recorded to our consolidated statement of comprehensive income.

Acquired Goodwill

The goodwill of $197.5 million represents future economic benefits expected to arise from anticipated synergies from the integration of Avitide. These synergies include certain cost savings, operating efficiencies and other strategic benefits projected to be achieved as a result of the Avitide Acquisition. Substantially all of the goodwill recorded is expected to be nondeductible for income tax purposes. In June 2022, the Company recorded an adjustment to goodwill of $1.8 million related to a change in estimated tax benefits associated with the net operating loss carryforward filed on the Avitide pre-acquisition tax return.

Polymem S.A.

On June 22, 2021, the Company entered into a Stock Purchase Agreement with Polymem, a company organized under the laws of France, and Jean-Michel Espenan and Franc Saux, acting together jointly and severally as the representatives of the sellers pursuant to which the Company acquired all of the outstanding common stock of Polymem for $47.0 million. The transaction closed on July 1, 2021 (the “Polymem Acquisition”).

Polymem, which is headquartered in, Toulouse, France, is a manufacturer of hollow fiber membranes, membrane modules and systems for industrial and bioprocessing applications. Polymem products will complement and expand the Company’s portfolio of hollow fiber systems and consumables. The acquisition substantially increases Repligen’s membrane and module manufacturing capacity and establishes a world-class center of excellence in Europe to address the accelerating global demand for these innovative products.

Consideration Transferred

The Polymem Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations,” and the Company engaged a third-party valuation firm to assist with the valuation of the business acquired. Payment for the transaction was denominated in Euros but is reflected here in U.S. dollars for presentation purposes based on an exchange rate of 0.8437 as of July 1, 2021, the date of acquisition. Total consideration paid was approximately $47.0 million, which included approximately $4.3 million deposited into an escrow account against which the Company may make claims for indemnification.

Under the acquisition method of accounting, the assets acquired and liabilities assumed of Polymem were recorded as of the acquisition date, at their respective fair values, and consolidated with those of the Company. The fair value of the net assets acquired is approximately $2.2 million, the fair value of the intangible assets acquired is approximately $9.1 million and the residual goodwill is approximately $35.7 million. Acquisition-related costs are not included as a component of consideration transferred but are expensed in the periods in which costs are incurred. The Company has incurred $6.3 million of transaction and integration costs associated with the Polymem Acquisition from the date of acquisition to June 30, 2022, with $1.6 million and $3.2 million of transaction and integration costs incurred during the three and six months ended June 30, 2022, respectively. The transaction costs are included in operating expenses in the consolidated statements of comprehensive income for the periods ended June 30, 2022.

Fair Value of Net Assets Acquired

The allocation of purchase price is based on the fair value of assets acquired and liabilities assumed as of the acquisition date, based on the final valuation of Polymem. The Company has made appropriate adjustments to the purchase price allocation during the measurement period, which ended on July 1, 2022.

Revenue Recognition

The Company generates revenue from the sale of bioprocessing products, equipment devices and related consumables used with these equipment devices to customers in the life science and biopharmaceutical industries. Under ASC 606, “Revenue from Contracts with Customers,” revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers.

Disaggregation of Revenue

Revenues for the three and six months ended June 30, 2022 and 2021 were as follows:

|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
|  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |
|  | (Amounts in thousands) |
Product revenue |  | $ | 207,597 |  |  | $ | 162,920 |  |  | $ | 413,960 |  |  | $ | 305,657 |
Royalty and other income |  |  | 36 |  |  |  | 40 |  |  |  | 73 |  |  |  | 140 |
Total revenue |  | $ | 207,633 |  |  | $ | 162,960 |  |  | $ | 414,033 |  |  | $ | 305,797 |

15

When disaggregating revenue, the Company considered all of the economic factors that may affect its revenues. 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 14, “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.

Contract Balances from Contracts with Customers

The following table provides information about receivables and deferred revenue from contracts with customers as of June 30, 2022 (amounts in thousands):

|  | June 30, |  |  | December 31, |
|  | 2022 |  |  | 2021 |
Balances from contracts with customers only: |  |  |  |  |  |
Accounts receivable |  | $ | 121,050 |  |  | $ | 117,420 |
Deferred revenue (included in accrued liabilities in the consolidated balance sheets) |  | $ | 22,161 |  |  | $ | 14,848 |
Revenue recognized during periods presented relating to: |  |  |  |  |  |
The beginning deferred revenue balance |  | $ | 11,215 |  |  | $ | 13,708 |

The timing of revenue recognition, billings and cash collections results in the accounts receivable and deferred revenue balances on the Company’s consolidated balance sheets.

A contract asset is created when the Company satisfies a performance obligation by transferring a promised good to the customer. Contract assets may represent conditional or unconditional rights to consideration. The right is conditional and recorded as a contract asset if the Company must first satisfy another performance obligation in the contract before it is entitled to payment from the customer. Contract assets are transferred to billed receivables once the right becomes unconditional. If the Company has the unconditional right to receive consideration from the customer, the contract asset is accounted for as a billed receivable and presented separately from other contract assets. A right is unconditional if nothing other than the passage of time is required before payment of that consideration is due.

When consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract, a contract liability is recorded. Contract liabilities are recognized as revenue after control of the products or services is transferred to the customer and all revenue recognition criteria have been met.

5.
Goodwill and Intangible Assets

Goodwill

16

Goodwill represents the difference between the purchase price and the estimated fair value of identifiable assets acquired and liabilities assumed. Goodwill acquired in a business combination and determined to have an indefinite useful life is not amortized, but instead is tested for impairment at least annually in accordance with ASC 350, “Intangibles – Goodwill and Other”.

The following table represents the change in the carrying value of goodwill for the six months ended June 30, 2022 (amounts in thousands):

Balance as of December 31, 2021 |  | $ | 860,362 |
Measurement period adjustment - BioFlex |  |  | (376 | )
Measurement period adjustment - Avitide |  |  | (1,784 | )
Cumulative translation adjustment |  |  | (3,874 | )
Balance as of June 30, 2022 |  | $ | 854,328 |

During each of the fourth quarters of 2021, 2020 and 2019, the Company completed its annual impairment assessments and concluded that goodwill was not impaired in any of those years. The Company has not identified any “triggering” events which indicate an impairment of goodwill in the three and six months ended June 30, 2022.

Intangible Assets

Intangible assets with a definitive life are amortized over their useful lives using the straight-line method, and the amortization expense is recorded within cost of product revenue and selling, general and administrative expenses in the Company’s statements of comprehensive income. Intangible assets and their related useful lives are reviewed at least annually to determine if any adverse conditions existed that would indicate the carrying value of these assets may not be recoverable. More frequent impairment assessments are conducted if certain conditions exist, including a change in the competitive landscape, any internal decisions to pursue new or different technology strategies, a loss of a significant customer, or a significant change in the marketplace, including changes in the prices paid for the Company's products or changes in the size of the market for the Company’s products. An impairment results if the carrying value of the asset exceeds the estimated fair value of the asset. If the estimate of an intangible asset’s remaining useful life is changed, the remaining carrying amount of the intangible asset is amortized prospectively over the revised remaining useful life. The Company continues to believe that its intangible assets are recoverable at June 30, 2022.

Indefinite-lived intangible assets are reviewed for impairment at least annually. There has been no impairment of the Company’s intangible assets for the periods presented.

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 second quarter of 2022, 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 third quarter of 2022, 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, $24,000 aggregate principal amount of the 2019 Notes have been converted by the note holders since the issuance of the 2019 Notes, including $13,000 in the first half of 2022. 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 consolidated balance sheet at June 30, 2022.

Prior to the adoption of ASU 2020-06, the Company accounted for the 2019 Notes as a liability and equity component where the carrying value of the liability component was valued based on a similar debt instrument. In accounting for the issuance of the

19

2019 Notes, the Company separated the 2019 Notes into liability and equity components. The carrying value of the liability component was calculated as the present value of its cash flows using a discount rate of 4.5% based on comparative convertible transactions for similar companies. The carrying value of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2019 Notes as a whole. The excess of the principal amount of the liability component over its carrying value amount, referred to as the debt discount, was amortized to interest expense on our consolidated statements of comprehensive income over the five-year term of the 2019 Notes. The equity component was not re-measured as long as it continued to meet the conditions for equity classification. The equity component related to the 2019 Notes recorded at issuance was $52.1 million, which was recorded in additional paid-in capital on the Company's consolidated balance sheets.

In accounting for the transaction costs related to the issuance of the 2019 Notes, the Company allocated the total costs incurred to the liability and equity components of the 2019 Notes using the same proportions as the initial carrying value of the 2019 Notes. Transaction costs related to the liability component were $7.4 million and are amortized to interest expense using the effective interest method over the five-year term of the 2019 Notes. Transaction costs attributable to the equity component were $1.6 million and are netted with the equity component of the 2019 Notes in stockholders' equity of the Company's consolidated balance sheets. Additionally, the Company recorded a net deferred tax liability of $11.4 million.

Effective January 1, 2022, the Company adopted ASU 2020-06. After adoption, the Company now accounts for the 2019 Notes as a single liability measured at amortized cost. As the equity component is no longer required to be split into a separate component, the Company recorded a net adjustment for the initial $50.4 million that was allocated to additional paid-in capital and $22.9 million of life-to-date interest expense recorded as amortization of debt discount. Additionally, the net deferred tax liability recorded for the 2019 Notes was reversed. The principal amount of the liability over its carrying amount is amortized to interest expense over the five-year term of the 2019 Notes. Since the 2019 Notes are classified as a single liability, there is no debt discount required to be amortized for the three and six months ended June 30, 2022.

The net carrying value of the liability component of the 2019 Notes is as follows:

|  | June 30, |  |  | December 31, |
|  | 2022 |  |  | 2021 |
|  | (Amounts in thousands) |
0.375% Convertible Senior Notes due 2024: |  |  |  |  |  |

At June 30, 2022 and December 31, 2021, the carrying value of the 2019 Notes was $283.7 million and $255.3 million, respectively, net of unamortized discount, and the fair value of the 2019 Notes was $432.3 million and $678.5 million, respectively. The fair value of the 2019 Notes was determined based on the most recent trade activity of the 2019 Notes at June 30, 2022 and December 31, 2021.

Stock Option and Incentive Plans

Under the Company’s current 2018 Stock Option and Incentive Plan (the “2018 Plan”), the number of shares of the Company’s common stock that are reserved and available for issuance is 2,778,000, plus the number of shares of common stock available for issuance under the Company’s previous equity plans. The shares of common stock underlying any awards under the 2018 Plan and previous equity plans (together, the “Plans”) that are forfeited, canceled or otherwise terminated (other than by exercise) shall be added back to the shares of stock available for issuance under the 2018 Plan. At June 30, 2022, 1,948,381 shares were available for future grants under the 2018 Plan.

Stock-Based Compensation

For each of the three months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $7.0 million and $7.1 million, respectively, for share-based awards granted under the Plans. For the six months ended June 30, 2022 and 2021, the Company recorded stock-based compensation expense of $14.9 million and $13.7 million, respectively. The following table presents stock-based compensation expense in the Company’s consolidated statements of comprehensive income:

|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |

The 2018 Plan allows for the granting of incentive and nonqualified options to purchase shares of common stock, restricted stock and other equity awards. Employee grants under the Plans generally vest over a three to five-year period, with 20%-33% vesting on the first anniversary of the date of grant and the remainder vesting in equal yearly installments thereafter.

Nonqualified options issued to non-employee directors under the Plans generally vest over one year. In the first quarter of 2018, to create a longer-term retention incentive, the Company’s Compensation Committee granted long-term incentive compensation awards to its Chief Executive Officer, which consisted of both stock options and restricted stock units (“RSUs”) that are subject to time-based vesting over nine years. Options granted under the Plans have a maximum term of ten years from the date of grant and generally, the exercise price of the stock options equals the fair market value of the Company’s common stock on the date of grant. At June 30, 2022, options to purchase 648,546 shares and 551,029 stock units were outstanding under the Plans.

Stock Options

The Company uses the Black-Scholes option pricing model to calculate the fair value of stock option awards on the grant date, and the Company uses the value of the common stock as of the grant date to value RSUs. The Company measures stock-based compensation costs for stock options at the grant date based on the estimated fair value of the award. 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 stock-based compensation expense for options that are ultimately expected to vest, and accordingly, such compensation expense has been adjusted for estimated forfeitures.

Represents the number of vested options as of June 30, 2022 plus the number of unvested options expected to vest as of June 30, 2022 based on the unvested outstanding options at June 30, 2022 adjusted for estimated forfeiture rates of 8% for awards granted to non-executive level employees and 3% for awards granted to executive level employees.

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 June 30, 2022, the last business day of the second quarter of 2022, of $162.40 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 June 30, 2022. The aggregate intrinsic value of stock options exercised during the six months ended June 30, 2022 and 2021 was $2.4 million and $6.0 million, respectively.

The weighted average grant date fair value of options granted during the six months ended June 30, 2022 and 2021 was $76.64 and $86.96, respectively. The total fair value of stock options that vested during the six months ended June 30, 2022 and 2021 was $2.7 million and $2.5 million, 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. Information regarding stock unit activity, which includes activity for RSUs and performance stock units, for the six months ended June 30, 2022 under the Plans is summarized below:

|  | Shares |  |  | Weighted- Average Remaining Contractual Term (in Years) |  |  | Aggregate Intrinsic Value (in Thousands) |
Unvested at December 31, 2021 |  |  | 606,685 |  |  |  | 3.07 |  |  | $ | 160,674 |

Represents the number of vested stock units as of June 30, 2022 plus the number of unvested stock units expected to vest as of June 30, 2022 based on the unvested outstanding stock units at June 30, 2022 adjusted for estimated forfeiture rates of 8% for awards granted to non-executive level employees and 3% for awards granted to executive level employees.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (equal to the closing price of the common stock on June 30, 2022, the last business day of the second quarter of 2022, of $162.40 per share, as stock units do not

22

have an exercise price) that would have been received by the stock unit holders had all holders exercised on June 30, 2022. The aggregate intrinsic value of stock units vested during the six months ended June 30, 2022 and 2021 was $37.5 million and $35.8 million, respectively.

The weighted average grant date fair value of stock units granted during the six months ended June 30, 2022 and 2021 was $191.09 and $206.15, respectively. The total fair value of stock units that vested during the six months ended June 30, 2022 and 2021 was $17.9 million and $9.6 million, respectively.

As of June 30, 2022, there was $70.4 million of total unrecognized compensation cost related to unvested share-based awards. This cost is expected to be recognized over a weighted average remaining requisite service period of 3.01 years. The Company expects 1,790,901 unvested options and stock units to vest over the next five years.

Commitments and Contingencies

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 COVID-19 vaccines. 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 for use in a platform use resin product. 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 $0.7 million and $0.3 million for the three months ended June 30, 2022 and 2021, respectively and payments of $1.1 million and $0.6 million for the six months ended June 30, 2022 and 2021, respectively.

11.
Income Taxes

For the three and six months ended June 30, 2022, we recorded an income tax provision of $9.9 million and $21.9 million, respectively. The Company’s effective tax rate for the three and six months ended June 30, 2022 was 16.6% and 18.4%, respectively, compared to 18.3% and 15.2% for the corresponding periods in the prior year. The difference in effective tax rates between the periods was primarily due to higher income before income taxes, lower windfall benefits recognized on stock option exercises and the vesting of stock units partially offset by lower U.S. taxation of foreign earnings. The effective tax rates for the three and six months ended June 30, 2022 and 2021 were lower than the U.S. statutory rate of 21% primarily due to business tax credits and windfall benefits on stock option exercises and the vesting of stock units.

12.
Earnings Per Share

23

The Company reports earnings per share (“EPS”) in accordance with ASC 260, “Earnings Per Share,” which establishes standards for computing and presenting EPS. Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income available to common shareholders by the weighted-average number of common shares and dilutive common share equivalents then outstanding. Potential common share equivalents consist of RSUs, performance stock units and the incremental common shares issuable upon the exercise of stock options. In periods when the Company has a net loss, stock awards are excluded from the calculation of EPS as their inclusion would have an antidilutive effect.

A reconciliation of basic and diluted weighted average shares outstanding is as follows:

At June 30, 2022, there were outstanding options to purchase 648,546 shares of the Company’s common stock at a weighted average exercise price of $62.42 per share and 551,029 shares of common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three and six months ended June 30, 2022, 325,685 shares and 306,400 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.

At June 30, 2021, there were outstanding options to purchase 682,913 shares of the Company’s common stock at a weighted average exercise price of $5 1.71 per share and 618,618 shares of common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three and six months ended June 30, 2021, 69,388 shares 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

24

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. As mentioned in Note 7, "Convertible Senior Notes," 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 six months ended June 30, 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 and six months ended June 30, 2022, the dilutive effect of the conversion premium included in the calculation of diluted earnings was 676,166 shares and 1,779,041 shares, respectively. For the three and six months ended June 30, 2021, the dilutive effect of the conversion premium included in the calculation of diluted earnings was 1,011,993 shares and 1,052,337 shares, respectively.

Related Party Transactions

Certain facilities leased by Spectrum are owned by the Roy T. Eddleman Living Trust (the "Trust"). As of June 30, 2022, the Trust owned greater than 5% of the Company’s outstanding shares. Therefore, the Company considers the Trust to be a related party. The lease amounts paid to the Trust prior to the public offering were negotiated in connection with the acquisition of Spectrum. The Company incurred rent expense totaling $0.2 million for each of the three months ended June 30, 2022 and 2021 related to these leases and incurred rent expense of $0.4 million for each of the six months ended June 30, 2022 and 2021.

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. Per the Company’s investment policy, cash equivalents and marketable securities are invested in financial instruments with high credit ratings and credit exposure to any one issue, issuer (with the exception of U.S. Treasury obligations) and type of instrument is limited. At June 30, 2022 and December 31, 2021, the Company had no investments associated with foreign exchange contracts, options contracts or other foreign hedging arrangements.

Concentration of credit risk with respect to accounts receivable is limited to customers to whom the Company makes significant sales. While a reserve for the potential write-off of accounts receivable is maintained, the Company has not written off any significant accounts to date. To control credit risk, the Company performs regular credit evaluations of its customers’ financial condition.

There was no revenue from customers that represented 10% or more of the Company's total revenue for the three and six months ended June 30, 2022 and 2021.

No accounts receivable balance from a specific customer represented 10% or more of the Company's total trade accounts receivable at June 30, 2022. Significant accounts receivable balances representing 10% or more of the Company’s total trade accounts receivable and royalties at December 31, 2021 came from our accounts receivable balance outstanding with Pfizer Inc., which was 14% of our total accounts receivable and other receivable balance.

Critical Accounting Policies and Estimates

A “critical accounting policy” is one which is both important to the portrayal of our financial condition and results and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. For a description of our critical accounting policies that affect our more significant judgments and estimates used in the preparation of our consolidated financial statements, refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations and our significant accounting policies in Note 2 to the consolidated financial statements included in our Form 10-K.

Results of Operations

The following discussion of the financial condition and results of operations should be read in conjunction with the accompanying consolidated financial statements and the related footnotes thereto.

Product revenues

Since 2016, we have been increasingly focused on selling our products directly to customers in the pharmaceutical industry and to our contract manufacturers. These direct sales represented approximately 89% and 83% of our product revenue for each of the three months ended June 30, 2022 and 2021, respectively, and represented 88% and 82% of our product revenue for each of the six months ended June 30, 2022 and 2021, respectively. We expect that direct sales will continue to account for an increasing percentage of our product revenues, as the largest customer of our OEM products diversified its supply chain in 2020. Sales of our bioprocessing products can be impacted by the timing of large-scale production orders and the regulatory approvals for such antibodies, which may result in significant quarterly fluctuations.

Revenues from our filtration franchise include the sales of our XCell ATF® systems and consumables; Spectrum filtration systems, including KrosFlo®; SIUS® filtration products and systems; the fluid management assemblies and components offered by Engineered Molding Technology LLC, Non-Metallic Solutions, Inc., ARTeSYN Biosolutions Holdings Ireland Limited ("ARTeSYN") and BioFlex, the latter of which was acquired on December 16, 2021; the hollow fiber membrane technology offered by Polymem, which we acquired on July 1, 2021; and our ARTeSYN filtration systems. Revenue from our chromatography products includes the sale of our OPUS pre-packed chromatography columns, ELISA test kits and chromatography systems from Spectrum and ARTeSYN. Revenue from proteins products includes the sale of our Protein A ligands and cell culture growth factors, and sales of affinity products, including adeno-associated virus resins offered by Avitide,

28

which we acquired on September 20, 2021. Revenue from our process analytics products includes the sale of our SoloVPE®, FlowVPE® and FlowVPX® systems, consumables and service. Other revenue primarily consists of sales of our operating room products to hospitals as well as freight revenue.

During the three and six months ended June 30, 2022, product revenue increased by $44.7 million, or 27.4% and $108.3 million, or 35.4%, respectively, as compared to the same periods of 2021, with exceptionally robust demand for our filtration, chromatography and process analytics products. There is continued adoption of our products by key bioprocessing customers across all key product lines. Since the second quarter of 2020, we began to experience accelerated demand across all of our franchises due to the critical needs of customers working on the novel coronavirus pandemic (“COVID-19”) vaccines. However, decreasing demand for vaccination is driving a reduction in future demand of our products from these customers and the recognition of future revenue related to COVID-19. In addition, we have recently seen an increased demand for C&GT and mAb manufacturing. We also experienced an increase in revenue during the three and six months ended June 30, 2022, compared to the same periods of 2021, due to our 2021 acquisitions which were acquired in the second half of 2021 and for which there was no comparable amounts in the three and six months ended June 30, 2021.

Royalty revenues

Royalty revenues in the three and six months ended June 30, 2022 and 2021 relate to royalties received from a third-party systems manufacturer associated with our OPUS PD chromatography columns. Royalty revenues are variable and are dependent on sales generated by our partner.

Costs of product revenue and operating expenses

Total costs and operating expenses for the three and six months ended June 30, 2022 and 2021 were comprised of the following:

|  | Three Months Ended June 30, | Increase/(Decrease) |  |  | Six Months Ended June 30, | Increase/(Decrease) |
|  | 2022 |  |  | 2021 |  |  | $ Change |  |  | % Change |  |  | 2022 |  |  | 2021 |  |  | $ Change |  |  | % Change |

Total costs and operating expenses |  | $ | 144,465 |  |  | $ | 114,720 |  |  | $ | 29,745 |  |  |  | 25.9 | % |  | $ | 290,865 |  |  | $ | 221,174 |  |  | $ | 69,691 |  |  |  | 31.5 | %

Cost of product revenue

Cost of product revenue increased 39.2% and 38.5% in the three and six months ended June 30, 2022, respectively, compared to the same periods of 2021, due primarily to the increase in product revenue mentioned above and costs associated with higher product volume. In addition, in order to support our growth and demand for our products, we continue to invest in our manufacturing infrastructure through an increase in headcount related to manufacturing and occupancy costs. In addition, freight charges and import duties increased during the three and six months ended June 30, 2022, compared to the same periods of 2021, due to increased fuel costs and carrier market conditions. Our depreciation expense increased during the three and six months ended June 30, 2022, as compared to the same periods of 2021, as manufacturing equipment was placed into service during the second half of 2021. In addition, cost of product revenue increased for the three and six months ended June 30, 2022 due to the addition of Polymem, Avitide and BioFlex during the second half of 2021 for which there were no comparable costs during the three and six months ended June 30, 2021.

Gross margin was 58.5% and 62.0% in the three months ended June 30, 2022 and 2021, respectively. The reduction in gross margin in the three months ended June 30, 2022, as compared to the same period of 2021, is due primarily to the increase in manufacturing and employee-related costs from a rise in manufacturing headcount, an increase in occupancy costs due to added capacity, an increase in depreciation expense, an increase in freight charges and import duties mentioned above.

29

Gross margin was 59.3% and 60.2% in the six months ended June 30, 2022 and 2021, respectively. The reduction in gross margin in the six months ended June 30, 2022, as compared to the same period of 2021, is due primarily to the increase in employee-related costs from a rise in manufacturing headcount, an increase in occupancy costs due to added capacity in 2021 and an increase in depreciation expense mentioned above. The gross margin for the six months ended June 30, 2021 also includes $1.6 million of amortization of inventory step-up associated with the ARTeSYN Acquisition in December 2020. Gross margins may fluctuate in future quarters based on actual production volume and product mix.

Research and development expenses

Research and development (“R&D”) expenses are related to bioprocessing products, which include personnel, supplies and other research expenses. Due to the size of the Company and the fact that these various programs share personnel and fixed costs, we do not track all of our expenses or allocate any fixed costs by program, and therefore, have not provided historical costs incurred by project.

R&D expenses increased $2.1 million, or 24.4% and $6.6 million, or 41.2%, during the three and six months ended June 30, 2022, respectively, compared to the same periods of 2021. The increase during the periods is primarily due to increased spending on new product development and investments in newly acquired businesses, for which there were no comparable costs in the three and six months ended June 30, 2021. The increase during the periods is also due in part to increased development project-related expenses and employee-related costs.

R&D expense also includes payments made to expand our proteins product offering through our development agreement with Navigo Proteins GmbH (“Navigo”). Such expenses were $0.7 million and $1.1 million, respectively, for the three and six months ended June 30, 2022, as compared to $0.3 million and $0.6 million, respectively for the same periods in 2021, in the form of milestone payments to Navigo.

We expect our R&D expenses for the remainder of 2022 to gradually increase each quarter to support new product development.

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, including legal, accounting, patent, shareholder services, amortization of intangible assets and other administrative functions.

During the three and six months ended June 30, 2022, SG&A costs increased by $10.3 million, or 23.2%, and $25.5 million, or 30.6%, respectively, as compared to the same periods of 2021. The increases are partially due to the continued expansion of our customer-facing activities to drive sales of our bioprocessing products, and the continued buildout of our administrative infrastructure, primarily through increased headcount, to support expected future growth. In addition, SG&A costs increased for the three and six months ended June 30, 2022 due to the addition of Polymem, Avitide and BioFlex during the second half of 2021, for which there are no comparable costs in the three and six months ended June 30, 2021.

Contingent consideration expense

Contingent consideration expense represents the change in fair value of the contingent consideration obligation included in current and noncurrent contingent consideration on the consolidated balance sheets as of the end of each period. Re-measurement 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 consolidated statements of comprehensive income. We recorded an adjustment to the fair value of the contingent consideration obligation for the three and six months ended June 30, 2022 of ($6.9) million and ($9.3) million, respectively.

The table below provides detail regarding our other expenses, net:

|  | Three Months Ended June 30, |  |  | Increase/(Decrease) |  |  | Six Months Ended June 30, |  |  | Increase/(Decrease) |
|  | 2022 |  |  | 2021 |  |  | $ Change |  |  | % Change |  |  | 2022 |  |  | 2021 |  |  | $ Change |  |  | % Change |

Investment income

Investment income includes income earned on invested cash balances. Our investment income increased by $0.7 million for the three and six months ended June 30, 2022, compared to the same periods of 2021 due to an increase in interest rates on average invested cash balances since June 30, 2021. We expect investment income to vary based on changes in the amount of funds invested and fluctuation of interest rates.

Interest expense

Interest expense in the three and six months ended June 30, 2022 and 2021 is primarily from our 0.375% Convertible Senior Notes due 2024 (the “2019 Notes”), which were issued in July 2019. Interest expense for the three and six months ended June 30, 2022 includes the contractual coupon interest on the 2019 Notes. For the three and six months ended June 30, 2021, interest expense includes the amortization of the debt discount as well as the contractual coupon interest. As a result of our adoption of ASU 2020-06, "Debt - Debt with Conversion Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40)," effective January 1, 2022, the equity portion of the debt conversion feature recorded upon the issuance of the 2019 Notes, or the debt discount, was reversed along with the total amortization taken on that discount. Since there was no debt discount, no amortization was taken in the three and six months ended June 30, 2022.

Amortization of debt issuance costs

In accounting for the transaction costs related to the issuance of the 2019 Notes, the Company allocated the total costs incurred to the liability and equity components of the 2019 Notes based on their relative values. Transaction costs attributable to the liability component are amortized to amortization of debt issuance costs on the consolidated statements of comprehensive income. Amortization of debt issuance costs increased during the three and six months ended June 30, 2022, as compared to the same periods of 2021. This is a result of the decrease in the balance of debt issuance costs that are being amortized. As these costs decrease, the carrying value of the debt increases and interest calculated based on the carrying value increases as well.

Other expenses

The change in other expenses, net during the three and six months ended June 30, 2022, compared to the same periods of 2021, is primarily attributable to realized foreign currency losses related to transactions with customers and vendors.

Income tax provision

Income tax provision for the three and six months ended June 30, 2022 and 2021 was as follows:

|  | Three Months Ended June 30, |  |  | Increase/(Decrease) |  |  | Six Months Ended June 30, |  |  | Increase/(Decrease) |
|  | 2022 |  |  | 2021 |  |  | $ Change |  |  | % Change |  |  | 2022 |  |  | 2021 |  |  | $ Change |  |  | % Change |
|  | (Amounts in thousands, except for percentage data) |
Income tax provision |  | $ | 9,895 |  |  | $ | 8,125 |  |  | $ | 1,770 |  |  |  | 21.8 | % |  | $ | 21,862 |  |  | $ | 11,780 |  |  | $ | 10,082 |  |  |  | 85.6 | %
Effective tax rate |  |  | 16.6 | % |  |  | 18.3 | % |  |  |  |  |  |  |  |  | 18.4 | % |  |  | 15.2 | % |  |  |  |  |  |

31

For the three and six months ended June 30, 2022, we recorded an income tax provision of $9.9 million and $21.9 million, respectively. The effective tax rate was 16.6% and 18.4% for the three and six months ended June 30, 2022, respectively, and is based upon the estimated income for the year ending December 31, 2022 and the composition of income in different jurisdictions. The difference in effective tax rates between the periods was primarily due to higher income before income taxes, lower windfall benefits recognized on stock option exercises and the vesting of stock units partially offset by lower U.S. taxation of foreign earnings. Our effective tax rate for the three and six months ended June 30, 2022 was lower than the U.S. statutory rate of 21% primarily due to business tax credits and windfall benefits on stock option exercises and the vesting of stock units. For the three and six months ended June 30, 2021, we recorded an income tax provision of $8.1 million and $11.8 million, respectively. The effective tax rate was 18.3% and 15.2% for the three and six months ended June 30, 2021, respectively, and is based upon the estimated income for the year ending December 31, 2021 and the composition of income in different jurisdictions. Our effective tax rate for the three and six months ended June 30, 2021 was lower than the U.S. statutory rate of 21% primarily due to business tax credits and windfall benefits on stock option exercise and the vesting of stock units.

Non-GAAP Financial Measures

We provide non-GAAP adjusted income from operations; adjusted net income; and adjusted EBITDA as supplemental measures to GAAP, measures regarding our operating performance. These financial measures exclude the items detailed below and, therefore, have not been calculated in accordance with GAAP. A detailed explanation and a reconciliation of each non-GAAP financial measure to its most comparable GAAP financial measure are provided below.

We include this financial information because we believe these measures provide a more accurate comparison of our financial results between periods and more accurately reflect how management reviews its financial results. We excluded the impact of certain acquisition-related items because we believe that the resulting charges do not accurately reflect the performance of our ongoing operations for the period in which such charges are incurred.

Non-GAAP adjusted income from operations

Non-GAAP adjusted income from operations is measured by taking income, from operations as reported in accordance with GAAP and excluding inventory step-up charges, acquisition and integration costs, contingent consideration fair value adjustments, and intangible amortization booked through our consolidated statements of comprehensive income. The following is a reconciliation of income from operations in accordance with GAAP to non-GAAP adjusted income from operations for the three and six months ended June 30, 2022 and 2021:

Non-GAAP adjusted net income

Non-GAAP adjusted net income is measured by taking net income as reported in accordance with GAAP and excluding acquisition and integration costs, intangible amortization, inventory step-up charges, loss on conversion of debt, non-cash interest expense, amortization of debt issuance costs, contingent consideration fair value adjustments and the tax effects of these items.

Liquidity and Capital Resources

We have financed our operations primarily through revenues derived from product sales, the issuance of the 2019 Notes in July 2019 and the issuance of common stock in our December 2020, July 2019 and May 2019 public offerings. Our revenue for the foreseeable future will primarily be limited to our bioprocessing product revenue.

At June 30, 2022, we had cash and cash equivalents of $596.5 million compared to cash and cash equivalents of $603.8 million at December 31, 2021.

During the second quarter of 2022, 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 third quarter of 2022, 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 fourth quarter of 2020. As a result, $24,000 in aggregate principal amount of the 2019 Notes have been converted by the noteholders since the issuance of the 2019 Notes, including $9,000 during the second quarter of 2022. The conversions resulted in the issuance of a nominal number of shares of the Company’s common stock to the noteholders. The Company continues to classify the carrying value of the 2019 Notes as current liabilities on the Company’s consolidated balance sheet at June 30, 2022.

Operating activities

For the six months ended June 30, 2022, our operating activities provided cash of $68.8 million reflecting net income of $96.8 million and non-cash charges totaling $31.5 million primarily related to depreciation, amortization, contingent consideration adjustments, deferred income taxes and stock-based compensation charges. An increase in accounts receivable consumed $8.4 million of cash and was primarily driven by the 35.4% year-to-date increase in revenues. Additionally, we had an increase in inventory manufactured of $58.1 million to support expected increases in future revenue. A decrease in accrued liabilities of $4.0 million relates to the payout of employee bonuses and a decrease in our estimated income tax provision during the first half of 2022. Offsetting these uses of cash was a $6.3 million increase in accounts payable which correlates to the increase in inventory and is also a result of the timing of payments to vendors and a decrease in prepaid expenses driven by a decrease in prepaid corporate income taxes. The remaining cash provided by operating activities resulted from favorable changes in various other working capital accounts.

For the six months ended June 30, 2021, our operating activities provided cash of $46.9 million reflecting net income of $65.7 million and non-cash charges totaling $43.8 million primarily related to depreciation, amortization, inventory step-up amortization, deferred income taxes, non-cash interest expense and stock-based compensation charges. An increase in accounts receivable consumed $31.9 million of cash and was primarily driven by the 87.0% year-to-date increase in revenues. Additionally, we had an increase in inventory manufactured of $42.8 million to support expected increases in future revenue. The increases in accounts receivable and inventory manufactured are offset by an increase in accounts payable of $8.3 million, which was primarily due to increased inventory purchases to support customer orders, an increase in accrued liabilities of $4.5 million, which was due to an increase in accruals for expected costs, and to a decrease in deferred revenue related to products shipped during the first half of 2021. The remaining cash used in operating activities resulted from unfavorable changes in various other working capital accounts.

Investing activities

Our investing activities consumed $54.4 million of cash during the six months ended June 30, 2022 and $26.2 million of cash during the six months ended June 30, 2021, mainly due to capital expenditures as we continue to increase our manufacturing capacity worldwide. Of these expenditures, $1.9 million and $2.2 million represented capitalized costs related to our internal-use software for the six months ended June 30, 2022 and 2021, respectively.

Financing activities

Our financing activities consumed $14.3 million of cash for the six months ended June 30, 2022, which included cash disbursed in relation to shares withheld to cover employee income tax due upon the vesting and release of restricted stock units of $14.8 million. This was partially offset by proceeds received from stock option exercises during the period of $0.5 million.

Cash provided by financing activities of $0.9 million for the six months ended June 30, 2021 included proceeds from stock option exercises during the period.

Working capital decreased by $3.9 million to $552.5 million at June 30, 2022 from $556.4 million at December 31, 2021 due to the various changes noted above.

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;

35

•
the extent of any share repurchase activity; and
•
the success of any proposed financing efforts.

Absent acquisitions of additional products, product candidates or intellectual property, we believe our current cash balances are adequate to meet our cash needs for at least the next 24 months from the date of this filing. We expect operating expenses for the rest of the year 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 and continued investment in our intellectual property portfolio.

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 acquiring products, technologies or businesses that would complement our existing portfolio. We continue to seek to acquire such potential assets that may offer us the best opportunity to create value for our shareholders. In order to acquire such assets, 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, including because of any such acquisition-related financing needs or lower demand for our products, 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.

Net Operating Loss Carryforwards

At December 31, 2021, the Company had federal net operating loss carryforwards of $46.2 million, state net operating loss carryforwards of $4.0 million and foreign net operating loss carryforwards of $6.1 million. Federal net operating loss carryforwards of $19.1 million will expire at various dates through 2037. The other $27.1 million of the federal net operating loss carryforwards have unlimited carryforward periods. The total state net operating loss carryforwards will expire at various dates through 2041, while the foreign net operating loss carryforwards do not expire. We had business tax credits carryforwards of $2.7 million available to reduce future federal and state income taxes, if any. The business tax credits carryforwards will continue to expire at various dates through December 2041. 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 shareholders.

Effects of Inflation

Our assets are primarily monetary, consisting of cash, cash equivalents and marketable securities. Because of their liquidity, these assets are not directly affected by inflation. Since we intend to retain and continue to use our equipment, furniture and fixtures 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.

operations or acquisitions, product development and sales, product candidate research, development and regulatory approval, SG&A expenditures, intellectual property, development and manufacturing plans, availability of materials and product and adequacy of capital resources, our financing plans and the projected continued impact of, and response to, COVID-19 constitute forward-looking statements. These forward-looking statements are based on current expectations, estimates, forecasts and projections about the industry and markets in which the Company operates, and management’s beliefs and assumptions. The Company undertakes no obligation to publicly update or revise the statements in light of future developments. In addition, other written and oral statements that constitute forward-looking statements may be made by the Company or on the Company’s behalf. Words such as “expect,” “seek,” “anticipate,” “intend,” “plan,” “believe,” “could,” “estimate,” “may,” “target,” “project,” or variations of such words and similar expressions are intended to identify forward-looking statements. Such forward-looking statements are subject to a number of risks and uncertainties that could cause actual results to differ materially from those anticipated, including, without limitation, risks associated with the following: the impact of COVID-19 on demand for our products and on our business or financial results; the success of current and future collaborative or supply relationships, including our agreements with Cytiva, MilliporeSigma and Purolite Life Sciences, an Ecolab Inc. company; our ability to successfully grow our bioprocessing business, including as a result of acquisitions, commercialization or partnership opportunities, and our ability to develop and commercialize products; our ability to obtain required regulatory approvals; our compliance with all U.S. Food and Drug Administration regulations, our ability to obtain, maintain and protect intellectual property rights for our products; the risk of litigation regarding our patent and other intellectual property rights; the risk of litigation with collaborative partners; our manufacturing capabilities and our dependence on third-party manufacturers and value-added resellers; the effect of COVID-19, including mitigation efforts and economic effects, on our business operations and the operations of our customers and suppliers; our ability to hire and retain skilled personnel; the market acceptance of our products, reduced demand for our products that adversely impacts our future revenues, cash flows, results of operations and financial condition; our ability to integrate Polymem, Avitide and BioFlex businesses successfully into our business and achieve the expected benefits of the acquisitions; our ability to compete with larger, better financed life sciences companies; our history of losses and expectation of incurring losses; our ability to generate future revenues; our ability to successfully integrate our recently acquired businesses; our ability to raise additional capital to fund potential acquisitions; our volatile stock price; and the effects of our anti-takeover provisions. Further information on potential risk factors that could affect our financial results are included in the filings made by us from time to time with the SEC including under the sections entitled “Risk Factors” in our Form 10-K.

ITEM 3. QUANTITATIVE AND QUAL ITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We have historically held investments in commercial paper, U.S. Government and agency securities as well as corporate bonds and other debt securities. As a result, we have been exposed to potential loss from market risks that may occur as a result of changes in interest rates, changes in credit quality of the issuer or otherwise. We do not have any such investments as of June 30, 2022. As a result, a hypothetical 100 basis point increase in interest rates would have no effect on our cash position as of June 30, 2022.

We generally place our marketable security investments in high quality credit instruments, as specified in our investment policy guidelines. We believe that the conservative nature of our investments mitigates our interest rate exposure, and our investment policy limits the amount of our credit exposure to any one issue, issuer (with the exception of U.S. agency obligations) and type of instrument. We do not expect any material losses from our marketable security investments and therefore believe that our potential interest rate exposure is limited.

Foreign Exchange Risk

The reporting currency of the Company is U.S. dollars, and the functional currency of each of our foreign subsidiaries is its respective local currency. Our foreign currency exposures include the Swedish krona, Euro, British pound, Chinese yuan, Japanese yen, Singapore dollar, South Korean won and Indian rupee; of these, the primary foreign currency exposures are the Swedish krona, Euro and British pound. Exchange gains or losses resulting from the translation between the transactional currency and the functional currency are included in net income. Fluctuations in exchange rates may adversely affect our results of operations, financial position and cash flows. We currently do not seek to hedge this exposure to fluctuations in exchange rates.

37

ITEM 4. CONTROLS AN D PROCEDURES

Disclosure Controls and Procedures

The Company’s management, with the participation of the principal executive officer and the principal financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. 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 effective at the reasonable assurance level.

Changes in Internal Control

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 June 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

38

PART II. OTHER INFORMATION

ITEM 1. LEG AL 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 adverse effect on our business, financial condition or results of operations.

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, 2021 and in subsequent filings, could cause our actual results to differ materially from those in the forward-looking statements.
