NOTES TO CONSOLIDATED 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 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, 2020 (“Form 10-K”), which was filed with the SEC on February 24, 2021.

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 (“COVID-19”) pandemic 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. (“C Technologies”), Engineered Molding Technology LLC (“EMT”), Non-Metallic Solutions, Inc. (“NMS”), ARTeSYN Biosolutions Holdings Ireland Limited (“ARTeSYN”) and Repligen Singapore Pte. Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation.

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 Accounting Standards Updates (“ASUs” or “ASU”) 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 Standard Updates – Not Yet Adopted

In August 2020, the Financial Accounting Standards Board (“FASB”) issued 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).” 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. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. ASU 2020-06 is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. This update permits the use of either the modified retrospective or fully retrospective method of transition. The Company is currently evaluating the timing and impact of the adoption of ASU 2020-06 on the Company’s consolidated financial statements.

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.

As of March 31, 2021 and December 31, 2020, cash and cash equivalents on the Company’s consolidated balance sheets included $544.1 million and $549.0 million, respectively, in a money market account. These funds are valued on a recurring basis using Level 1 inputs.

In July 2019, the Company issued $287.5 million aggregate principal amount of the Company’s 0.375% Convertible Senior Notes due July 15, 2024 (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 March 31, 2021 and December 31, 2020, the carrying value of the 2019 Notes was $246.6 million and $243.7 million, respectively, net of unamortized discount, and the fair value of the 2019 Notes was $502.0 million and $501.0 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 March 31, 2021. The 2019 Notes are discussed in more detail in Note 12, “Convertible Senior Notes” to Part II, Item 8, “Financial Statements and Supplementary Data” to our Form 10-K.

During the three months ended March 31, 2021, there were no remeasurements to fair value of financial assets and liabilities that are not measured at fair value on a recurring basis.

3. Acquisitions

ARTeSYN Biosolutions Holdings Ireland Limited

On October 27, 2020, the Company entered into an Equity and Asset Purchase Agreement with ARTeSYN, a company organized under the laws of Ireland, Third Creek Holdings, LLC, a Nevada limited liability company (“Third Creek”), Alphinity, LLC, a Nevada limited liability company (“Alphinity”, and together with Third Creek the “ARTeSYN Sellers”), and Michael Gagne, solely in his capacity as the representative of the ARTeSYN Sellers, pursuant to which the Company acquired (i) all of the outstanding equity securities of ARTeSYN and (ii) certain assets from Alphinity related to the business of ARTeSYN (collectively, the “ARTeSYN Acquisition”) for approximately $200 million, comprised of approximately $130 million in cash to the ARTeSYN Sellers and approximately $70 million in the Company’s common stock to Third Creek. The transaction closed on December 3, 2020.

8

ARTeSYN is headquartered in Waterford, Ireland and conducts its operations in Ireland, the United States and Estonia. Its suite of single-use solutions has been created with the goal of enabling “abundance in medicine” by allowing 10x greater efficiency in biologics manufacturing. The ARTeSYN team has created a number of solutions targeting the single-use space from single-use valves with fully disposable valve liners, XO® skeletal supports, a hybrid small parts offering for de-bottlenecking traditional facilities, and fully automated SU process systems that have quickly become leading solutions in the bioprocessing industry. In addition to its single-use solutions, ARTeSYN also engages in the manufacture of large-scale systems to be used for biologics manufacturing. ARTeSYN has established downstream processing leadership with a suite of state of the art single-use systems for chromatography, filtration, continuous manufacturing and media/buffer prep workflows. In addition, the Company has integrated unique flow path assemblies utilizing EMT’s silicone extrusion and molding technology, to deliver highly differentiated, low hold-up volume systems that minimize product loss during processing.

Consideration Transferred

The ARTeSYN Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations”. The ARTeSYN Acquisition was funded through payment of $130.7 million in cash, as well as issuance of 372,990 unregistered shares of the Company’s common stock totaling $69.4 million, contingent consideration of approximately $1.5 million, and settlement of preexisting invoices with the Company of approximately $2.3 million, for a total purchase price of $204.0 million. Under the acquisition method of accounting, the assets acquired and liabilities assumed of ARTeSYN 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 tangible assets acquired is estimated to be $7.9 million, the fair value of the intangible assets acquired is estimated to be $67.4 million, and the residual goodwill is estimated to be $128.7 million. The estimated consideration and preliminary purchase price information has been prepared using a preliminary valuation. Payment of the final consideration for working capital was made in April 2021.

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	$	130,713
Equity consideration		69,422
Contingent consideration		1,548
Settlement of preexisting liabilities		2,310
Fair value of net assets acquired	$	203,993

Acquisition related costs are not included as a component of consideration transferred but are expensed in the periods in which the costs are incurred. The Company incurred $4.0 million in transaction and integration costs associated with the ARTeSYN Acquisition in 2020 and an additional $0.5 million of transaction and integration costs during the first quarter of 2021. The transaction costs are included in selling, general and administrative (“SG&A”) expenses in the consolidated statements of comprehensive income. 

The consideration transferred includes approximately $1.5 million related to consideration that was deferred at the acquisition date, with payment to the ARTeSYN Sellers contingent upon recognizing revenue on a large-scale system within 120 days of the acquisition date. This consideration is recorded at its estimated fair value as of the acquisition date, which includes the assumption of high probability of such revenue being recognized. During the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to 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 are recorded to our consolidated statements of comprehensive income.

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 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 December 3, 2020). Any such revision or changes may be material. The final allocation may include changes to: (1) deferred revenue; (2) inventory; (3) deferred tax liabilities, net; (4) allocations to intangible assets such as tradenames, developed technology and customer relationships as well as goodwill; and (5) other assets and liabilities. In March 2021, the Company recorded a $0.1 million working capital adjustment related to settlement of a pre-acquisition liability, which offset goodwill in the table below.

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

Cash and cash equivalents	$	2,982
Accounts receivable		4,811
Inventory		8,592
Prepaid expenses and other current assets		5,561
Property and equipment		1,836
Operating lease right of use asset		1,611
Other noncurrent assets		26
Customer relationships		38,400
Developed technology		27,060
Trademark and tradename		1,630
Non-competition agreements		300
Goodwill		128,748
Accounts payable		(2,251	)
Accrued liabilities		(8,856	)
Deferred revenue		(3,583	)
Deferred tax liabilities, net		(1,240	)
Notes payable		(24	)
Operating lease liability		(417	)
Operating lease liability, long-term		(1,193	)
Fair value of net assets acquired	$	203,993

Acquired Goodwill

The goodwill of $128.7 million represents future economic benefits expected to arise from synergies from combining operations and commercial organizations to increase market presence and the extension of existing customer relationships. 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 ARTeSYN Acquisition and their estimated useful lives:

	Useful life		Fair Value
			(Amounts in thousands)
Customer relationships		17 years	$	38,400
Developed technology		15 years		27,060
Trademark and tradename		21 years		1,630
Non-competition agreements		3 years		300
			$	67,390

Non-Metallic Solutions, Inc.

On October 15, 2020, the Company entered into a Stock Purchase Agreement with NMS, a Massachusetts corporation, and each of William Malloneé and Derek Masser, the legal and beneficial owners of NMS, to purchase NMS, which transaction subsequently closed on October 20, 2020 (the “NMS Acquisition”).

NMS, headquartered in Auburn, Massachusetts, is a manufacturer of fabricated plastics, custom containers, and related assemblies and components used in the manufacturing of biologic drugs. The acquisition of NMS allows Repligen to expand its line of single-use systems and associated integrated flow path assemblies, streamline the supply chain for current products, and gives the Company more flexibility to scale and expand single-use and systems portfolios.

Consideration Transferred

The NMS Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations.” Total consideration paid was $16.1 million, which included $1.3 million deposited into an escrow account against which the Company may make claims for indemnification. The fair value of the net tangible assets acquired is estimated to be approximately $0.9 million, the fair value of the intangible assets acquired is estimated to be $8.5 million, and the residual goodwill is estimated to be approximately $6.7 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 incurred $0.2 million of transaction and integration costs associated with the NMS Acquisition in 2020 and $0.2 million in 2021. The transaction costs are included in SG&A expenses in the consolidated statements of comprehensive income. 

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 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 October 20, 2020).

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

Cash and cash equivalents	$	1,163
Accounts receivable		415

Fair value of net assets acquired	$	16,099

Acquired Goodwill

The goodwill of $6.7 million represents future economic benefits expected to arise from anticipated synergies from the integration of NMS. These synergies include certain cost savings, operating efficiencies and other strategic benefits projected to be achieved as a result of the NMS Acquisition. Substantially all of the goodwill recorded is expected to be deductible for income tax purposes. In February 2021, the Company recorded an adjustment to goodwill of $0.1 million related to the finalization of the working capital true-up.

Engineered Molding Technology LLC

On July 13, 2020, the Company completed the acquisition of 100% of the membership interests of EMT, a New York limited liability company, pursuant to a Membership Interest Purchase Agreement, dated June 26, 2020, by and among the Company, EMT, and each of Michael Pandori and Todd Etesse, the legal and beneficial owners of EMT (such acquisition, the “EMT Acquisition”).

EMT, headquartered in Clifton Park, New York, is an innovator and manufacturer of single-use silicone assemblies and components used in the manufacturing of biologic drugs. EMT’s standard and custom molding as well as their over-molded connectors and silicone tubing products are key components in single-use filtration and chromatography systems. EMT’s products will complement and expand Repligen’s single-use product offerings.

Consideration Transferred

The EMT Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations”. Total consideration paid was $28.5 million, which included $2.2 million deposited into an escrow account against which the Company may make claims for indemnification. Under the acquisition method of accounting, the net assets of EMT were recorded as of the acquisition date, at their respective fair values, and consolidated with those of Repligen. The fair value of the net tangible assets acquired is approximately $1.5 million, the fair value of the intangible assets acquired is approximately $14.4 million, and the residual goodwill is approximately $12.6  million. The estimated consideration and preliminary purchase price information have been prepared using a preliminary valuation. 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 Repligen believes to be reasonable. 

Acquisition-related costs are not included as a component of consideration transferred but are expensed in the periods in which the costs are incurred. The Company incurred $1.2  million of transaction and integration related costs associated with the EMT Acquisition in 2020 and  $0.1 million during the first quarter of 2021. The transaction costs are included in SG&A expenses in the consolidated statements of comprehensive income.

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 preliminary valuation. The Company obtained this information during due diligence and through other sources. In the months after the closing, the Company obtained additional information about these assets and liabilities as it learned more about EMT. The Company refined the estimates of fair value to more accurately allocate the purchase price. Only items identified as of the acquisition date were considered for subsequent adjustment. We have made appropriate adjustments to the purchase price allocation during the measurement period, which ends on July 13, 2021. We consider these adjustments to be final. The components and allocation of the purchase price consist of the following (amounts in thousands):

Cash and cash equivalents	$	69
Accounts receivable		1,057
Inventory		449
Prepaid expenses and other current assets		7
Property and equipment		414
Operating lease right of use assets		1,050
Customer relationships		11,080
Developed technology		2,910
Trademark and tradename		320
Non-compete agreements		50
Goodwill		12,585
Deferred tax asset		46
Accounts payable		(283	)
Accrued liabilities		(190	)
Operating lease liability		(211	)
Operating lease liability, long-term		(839	)
Fair value of net assets acquired	$	28,514

Acquired Goodwill

The goodwill of $12.6 million represents future economic benefits expected to arise from anticipated synergies from the integration of EMT. These synergies include certain cost savings, operating efficiencies and other strategic benefits projected to be achieved as a result of the EMT 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 EMT Acquisition and their estimated useful lives:

4. 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.

13

Disaggregation of Revenue

Revenues for the three months ended March 31, 2021 and 2020 were as follows:

	Three Months Ended
	March 31,
	2021		2020
	(Amounts in thousands)
Product revenue	$	142,737	$	76,060
Royalty and other income		100		30
Total revenue	$	142,837	$	76,090

When disaggregating revenue, the Company considered all of the economic factors that may affect its revenues. Because 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, factors such as regulatory and geopolitical factors within those regions could impact the nature, timing and uncertainty of the Company’s revenues and cash flows. In addition, a significant portion of the Company’s revenues are 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 can be found in Note 14, “Segment Reporting,” included in this report.

Except for the $10.9 million of revenue with MilliporeSigma for the three months ended March 31, 2020, there were no significant customers that represented 10% or more of total revenue for the periods presented in the table above.

For more information regarding our product revenue, see Note 5, “Revenue Recognition” included in Part II, Item 8, “Financial Statements and Supplementary Data” to our Form 10-K, which was filed with the SEC on February 24, 2021.

Contract Balances from Contracts with Customers

The following table provides information about receivables and deferred revenue from contracts with customers as of March 31, 2021 (amounts in thousands):

	2021
Balances from contracts with customers only:
Accounts receivable	$	90,207
Deferred revenue (included in accrued liabilities in the consolidated balance sheets)	$	14,253
Revenue recognized during the three-month period ended March 31, 2021 relating to:
The beginning deferred revenue balance	$	8,525
Changes in pricing related to products or services satisfied in previous periods	$	—

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

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 three months ended March 31, 2021 (amounts in thousands):

Balance at December 31, 2020	$	618,305
Measurement period adjustment - NMS		(71	)
Measurement period adjustment - ARTeSYN		90
Cumulative translation adjustment		(807	)
Balance at March 31, 2021	$	617,517

During each of the fourth quarters of 2020, 2019 and 2018, 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 months ended March 31, 2021.

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 SG&A 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 our 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 March 31, 2021.

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

7. Convertible Senior Notes

0.375% Convertible Senior Notes due 2024

On July 19, 2019, the Company issued $287.5 million aggregate principal pursuant to the 2019 Notes, which includes the underwriters’ exercise in full of an option to purchase an additional $37.5 million aggregate principal amount of 2019 Notes (the “Notes Offering”). The net proceeds of the Notes Offering, after deducting underwriting discounts and commissions and other related offering expenses payable by the Company, were approximately $278.5 million. The 2019 Notes are senior, unsecured obligations of the Company, and bear interest at a rate of 0.375% per year. Interest is payable semi-annually in arrears on January 15 and July 15 of each year, beginning on January 15, 2020. The 2019 Notes will mature on July 15, 2024, unless earlier repurchased or converted in accordance with their terms.

During the first quarter of 2021, the closing price of the Company’s common stock exceeded 130% of the conversion price of the 2019 Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the 2019 Notes are convertible at the option of the holders of the 2019 Notes during the second quarter of 2021, the quarter immediately following the quarter when the conditions are met, as stated in the terms of the 2019 Notes. These conditions were also met during the fourth quarter of 2020 and as a result, the Company received notices from note holders that they would convert $5,000 aggregate principal amount of the 2019 Notes, of which $1,000 principal were settled during the first quarter of 2021. The conversion resulted in the issuance of a nominal number of shares of the Company’s common stock to the note holders, and the Company recorded a loss of approximately  $1,000 on the conversion of these notes, which is included in other (expenses) income on our consolidated statements of comprehensive income for the three months ended March 31, 2021. The Company continues to classify the carrying value of the 2019 Notes as current liabilities on the Company’s consolidated balance sheet at March 31, 2021.

17

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

	March 31,			December 31,
	2021			2020
	(Amounts in thousands)
0.375% Convertible Senior Notes due 2024:
Principal amount	$	287,499		$	287,500
Unamortized debt discount		(35,843	)		(38,317	)
Unamortized debt issuance costs		(5,095	)		(5,446	)
Net carrying amount	$	246,561		$	243,737

Interest expense recognized on the 2019 Notes for the three months ended March 31, 2021 was $0.3 million, $2.5 million and $0.4 million for the contractual coupon interest, the accretion of the debt discount and the amortization of the debt issuance costs, respectively. The effective interest rate on the 2019 Notes is 5.1%, which included the interest on the 2019 Notes, amortization of the debt discount and debt issuance costs. At March 31, 2021 and December 31, 2020, the carrying value of the 2019 Notes was $246.6 million and $243.7 million, respectively, net of unamortized discount, and the fair value of the 2019 Notes was $502.0 million and $501.0 million, respectively. The fair value of the 2019 Notes was determined based on the most recent trade activity of the 2019 Notes at March 31, 2021.

8. Stockholders’ Equity

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 plans. The shares of common stock underlying any awards under the 2018 Plan and previous 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 March 31, 2021, 2,179,921 shares were available for future grants under the 2018 Plan.

Stock-Based Compensation

For the three months ended March 31, 2021 and 2020, the Company recorded stock-based compensation expense of $6.5 million and $4.2 million, respectively, for share-based awards granted under the Plans. The following table presents stock-based compensation expense in the Company’s consolidated statements of comprehensive income:

	Three Months Ended March 31,
	2021		2020
	(Amounts in thousands)
Cost of product revenue	$	506	$	433
Research and development		716		372
Selling, general and administrative		5,319		3,360
Total stock-based compensation	$	6,541	$	4,165

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 consisting 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 March 31, 2021, options to purchase 697,118 shares and 654,250 stock units were outstanding under the Plans.

18

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 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. Prior to 2020, the Company issued performance stock units to certain employees which are tied to the achievement of certain Company financial goal metrics and the passage of time. During 2020, the Company implemented a formal program that issued performance stock units to certain employees set to vest upon the achievement of individual goals and the passage of time. The Company recognizes expense on performance-based awards over the vesting period based on the probability that the performance metrics will be achieved. 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.

Information regarding option activity for the three months ended March 31, 2021 under the Plans is summarized below:

	Shares			Weighted average exercise price		Weighted- Average Remaining Contractual Term (in Years)		Aggregate Intrinsic Value (in Thousands)
Options outstanding at December 31, 2020		696,711		$	43.88		6.90	$	102,958
Granted		21,547		$	215.58
Exercised		(15,140	)	$	33.25
Forfeited/expired/cancelled		(6,000	)	$	48.05
Options outstanding at March 31, 2021		697,118		$	49.39		6.76	$	101,554
Options exercisable at March 31, 2021		384,757		$	34.20		6.00	$	61,641
Vested and expected to vest at March 31, 2021(1)		669,196					6.72	$	98,009

(1) Represents the number of vested options as of March 31, 2021 plus the number of unvested options expected to vest as of March 31, 2021 based on the unvested outstanding options at March 31, 2021 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 March 31, 2021, the last business day of the first quarter of 2021, of $194.41 per share and the exercise price of each in-the-money option) that would have been received by the option holders had all option holders exercised their options on March 31, 2021. The aggregate intrinsic value of stock options exercised during the three months ended March 31, 2021 and 2020 was $2.5 million and $4.7 million, respectively.

The weighted average grant date fair value of options granted during the three months ended March 31, 2021 and 2020 was $92.35 and $41.77, respectively. The total fair value of stock options that vested during the three months ended March 31, 2021 and 2020 was $1.9 million and $2.0 million, respectively.

19

The fair value of stock units is calculated using the closing price of the Company’s common stock on the date of grant. Information regarding stock unit activity, which includes activity for RSUs and performance stock units, for the three months ended March 31, 2021 under the Plans is summarized below:

	Shares			Weighted- Average Remaining Contractual Term (in Years)		Aggregate Intrinsic Value (in  Thousands)
Unvested at December 31, 2020		665,540			3.32	$	127,904
Awarded		119,148
Vested		(122,765	)
Forfeited/expired/cancelled		(7,673	)
Unvested at March 31, 2021		654,250			3.09	$	127,193
Unvested and expected to vest at March 31, 2021(1)		639,254			2.94	$	124,277

(1) Represents the number of vested stock units as of March 31, 2021 plus the number of unvested stock units expected to vest as of March 31, 2021 based on the unvested outstanding stock units at March 31, 2021 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 March 31, 2021, the last business day of the first quarter of 2021, of  $194.41 per share, as stock units do not have an exercise price) that would have been received by the stock unit holders had all holders exercised on March 31, 2021. The aggregate intrinsic value of stock units vested during the three months ended March 31, 2021 and 2020 was $27.1 million and $11.8 million, respectively.

The weighted average grant date fair value of stock units vested during the three months ended March 31, 2021 and 2020 was $209.13 and $86.75, respectively. The total fair value of stock units that vested during the three months ended March 31, 2021 and 2020 was $6.5 million and $5.3 million, respectively.

As of March 31, 2021, there was $65.4 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 3.25 years. The Company expects 1,894,207 unvested options and stock units to vest over the next five years.

9. Commitments and Contingencies

In June 2018, the Company secured an agreement with Navigo Proteins (“Navigo”) for the exclusive co-development of multiple affinity ligands for which Repligen holds commercialization rights. The Company is manufacturing and has agreed to supply the first of these ligands, NGL-Impact®, exclusively to Purolite Life Sciences (“Purolite”), who will pair 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 will be marketed by the Company. 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 $0.3 million for the three months ended March 31, 2021. No royalty payments were made to Navigo during the three months ended March 31, 2020.

11. Income Taxes

For the three months ended March 31, 2021, we recorded an income tax provision of $3.7 million. The Company’s effective tax rate for the three months ended March 31, 2021 was 11%, compared to 8.1% for the corresponding period in the prior year. The effective tax rates for the three months ended March 31, 2021 and 2020 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.

On March 27, 2020, President Trump signed the $2.2 trillion bipartisan Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. The CARES Act, the third congressional bill to address COVID-19, provides for loans and other benefits to businesses, expanded unemployment insurance, direct payments to those with middle-income and below wages, new appropriations funding for healthcare and other priorities, and tax changes, including deferrals of employer payroll tax liabilities, coupled with an employee retention tax credit and rollbacks of TCJA limitations on net operating losses (“NOLs”) and the Section 163(j) business interest limitation and a TCJA technical correction on qualified improvement property. The Company evaluated the provisions of the CARES Act and no provision had a material effect on the Company’s financial position or results of operations.

The Company’s tax returns are subject to examination by federal, state and international tax authorities for the following periods:

Jurisdiction	Fiscal Years Subject to Examination
United States - federal and state	2017-2020
Sweden	2013-2020

12. Earnings Per Share

The Company reports earnings per share in accordance with ASC 260, “Earnings Per Share,” which establishes standards for computing and presenting earnings per share. Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share 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. Under the treasury stock method, unexercised “in-the-money” stock options and warrants are assumed to be exercised at the beginning of the period or at issuance, if later. The assumed proceeds are then used to purchase common shares at the average market price during the period. In periods when the Company has a net loss, stock awards are excluded from the calculation of earnings per share as their inclusion would have an antidilutive effect.

21

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

	Three Months Ended March 31,
	2021		2020
	(Amounts in thousands, except per share data)
Net income	$	29,450	$	9,815
Weighted average shares used in computing net income per share - basic		54,805		52,139
Effect of dilutive shares:
Options and stock units		964		970
Convertible Senior Notes		1,092		—
Dilutive effect of unvested performance stock units		8		—
Dilutive potential common shares		2,064		970
Weighted average shares used in computing net income per share - diluted		56,869		53,109
Earnings per share:
Basic	$	0.54	$	0.19
Diluted	$	0.52	$	0.18

At March 31, 2021, there were outstanding options to purchase 697,118 shares of the Company’s common stock at a weighted average exercise price of $49.39 per share and 654,250 shares of common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three months ended March 31, 2021, 94,236 shares of the Company’s common stock were excluded from the calculation of diluted earnings per share 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 March 31, 2020, there were outstanding options to purchase 915,518 shares of the Company’s common stock at a weighted average exercise price of $32.91 per share and 716,630 common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three months ended March 31, 2020, 39,711 shares of the Company’s common stock were excluded from the calculation of diluted earnings per share 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, conversion of the 2019 Notes will be settled in cash, shares of the Company’s common stock or a combination thereof, at the Company’s election. As of March 31, 2021, the 2019 Notes were convertible. The Company currently intends to settle the par value of the 2019 Notes in cash and any excess conversion premium in shares.

As provided by the terms of the indenture underlying the 2019 Notes, the Company has a choice to settle the conversion obligation for the 2019 Notes in cash, shares or any combination of the two. The Company currently intends to settle the par value of the 2019 Notes in cash and any excess conversion premium in shares. The Company applies the provisions of ASC 260, “Earnings Per Share”, Subsection 10-45-44, to determine the diluted weighted average shares outstanding as it relates to the conversion spread on its convertible notes. Accordingly, the par value of the 2019 Notes is not included in the calculation of diluted income per share, but the dilutive effect of the conversion premium is considered in the calculation of diluted net income per share using the treasury stock method. The dilutive impact of the 2019 Notes is based on the difference between the Company’s current period average stock price and the conversion price of the 2019 Notes, provided there is a premium. Pursuant to this accounting standard, there is no dilution from the accreted principal of the 2019 Notes. For the three months ended March 31, 2021, the dilutive effect of the conversion premium included in the calculation of diluted earnings was 1,091,776 shares. There was no dilutive effect of the conversion premium included in the calculation of diluted earnings per share for the three months ended March 31, 2020.

13. Related Party Transactions

Certain facilities leased by Spectrum are owned by Roy Eddleman, the former owner of Spectrum. As of March 31, 2021, Mr. Eddleman owned greater than 5% of the Company’s outstanding shares and the Company considers him to be a related party.

22

The lease amounts paid to this shareholder prior to the public offering were negotiated in connection with the acquisition of Spectrum. The Company incurred rent expense totaling $0.2 million for the three months ended March 31, 2021 and 2020 related to these leases.

14. Segment Reporting

The Company views its operations, makes decisions regarding how to allocate resources and manages its business as one reportable segment and one reporting unit. As a result, the financial information disclosed herein represents all of the material financial information related to the Company.

The following table represents the Company’s total revenue by geographic area (based on the location of the customer):

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 March 31, 2021 and December 31, 2020, 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.

No revenue from customers represented 10% or more of the Company’s total revenue for the three months ended March 31, 2021. Revenue from MilliporeSigma represented 14% of the Company’s total revenue for the three months ended March 31, 2020.

At March 31, 2021, there were no accounts receivable balances with customers representing 10% or more of the Company’s total trade accounts receivable balance.

Building on over 35 years of industry expertise, we have developed a broad and diversified product portfolio that reflects our passion for innovation and the customer-first culture that drives our entire organization. We continue to capitalize on opportunities to maximize the value of our product platform through both organic growth initiatives (internal innovation and commercial leverage) and targeted acquisitions.

Acquisitions

ARTeSYN Biosolutions Holdings Ireland Limited

On October 27, 2020, we entered into an Equity and Asset Purchase Agreement with ARTeSYN Biosolutions Holdings Ireland Limited (“ARTeSYN”), a company organized under the laws of Ireland, Third Creek Holdings, LLC, a Nevada limited liability company (“Third Creek”), Alphinity, LLC, a Nevada limited liability company (“Alphinity”, and together with Third Creek the “ARTeSYN Sellers”), and Michael Gagne, solely in his capacity as the representative of the ARTeSYN Sellers, pursuant to which the Company acquired (i) all of the outstanding equity securities of ARTeSYN and (ii) certain assets from Alphinity related to the business of ARTeSYN (collectively, the “ARTeSYN Acquisition”) for approximately $200 million, comprised of approximately $130 million in cash to the ARTeSYN Sellers and approximately $70 million in our common stock to Third Creek. The transaction closed on December 3, 2020.

ARTeSYN is headquartered in Waterford, Ireland and conducts its operations in Ireland, the United States and Estonia. Its suite of single-use solutions has been created with the goal of enabling “abundance in medicine” by allowing 10x greater efficiency in biologics manufacturing. The ARTeSYN team has created a number of solutions targeting the single-use space from single-use valves with fully disposable valve liners, XO® skeletal supports, a hybrid small parts offering for de-bottlenecking traditional facilities, and fully automated SU process systems that have quickly become leading solutions in the bioprocessing industry. In addition to its single-use solutions, ARTeSYN also engages in the manufacture of large-scale systems to be used for biologics manufacturing. ARTeSYN has established downstream processing leadership with a suite of state of the art single-use systems for chromatography, filtration, continuous manufacturing and media/buffer prep workflows. In addition, we have integrated unique flow path assemblies utilizing Engineered Molding Technology LLC’s (“EMT”) silicone extrusion and molding technology, to deliver highly differentiated, low hold-up volume systems that minimize product loss during processing.

Non-Metallic Solutions, Inc.

On October 15, 2020, we executed a Stock Purchase Agreement with Non-Metallic Solutions, Inc. (“NMS”), a Massachusetts corporation, and each of William Malloneé and Derek Masser, the legal and beneficial owners of NMS, to purchase NMS, which transaction subsequently closed on October 20, 2020 (the “NMS Acquisition”).

NMS, headquartered in Auburn, Massachusetts, is a manufacturer of fabricated plastics, custom containers, and related assemblies and components used in the manufacturing of biologic drugs. The acquisition of NMS allows us to expand its line of single-use systems and associated integrated flow path assemblies, streamline the supply chain for current products, and gives us more flexibility to scale and expand single-use and systems portfolios.

24

Engineered Molding Technology LLC

On July 13, 2020, we completed the acquisition of 100% of the membership interests of EMT, a New York limited liability company, pursuant to a Membership Interest Purchase Agreement, dated June 26, 2020, by and among the Company, EMT, and each of Michael Pandori and Todd Etesse, the legal and beneficial owners of EMT (such acquisition, the “EMT Acquisition”).

EMT, headquartered in Clifton Park, New York, is an innovator and manufacturer of single-use silicone assemblies and components used in the manufacturing of biologic drugs. EMT’s standard and custom molding as well as their over-molded connectors and silicone tubing products are key components in single-use filtration and chromatography systems. EMT’s products will complement and expand our single-use product offerings.

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.

Revenues

Total revenue for the three months ended March 31, 2021 and 2020 were as follows:

	Three Months Ended March 31,				Increase/(Decrease)
	2021		2020		$ Change		% Change
	(Amounts in thousands, except for percentage data)
Revenue:
Products	$	142,737	$	76,060	$	66,677		87.7	%
Royalty and other		100		30		70		233.3	%
Total revenue	$	142,837	$	76,090	$	66,747		87.7	%

Product revenues

Direct sales represented approximately 80% and 76% of our product revenue for the three months ended March 31, 2021 and 2020, 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.

Revenue from our chromatography products includes the sale of our OPUS chromatography columns, chromatography resins and ELISA test kits. Revenue from our filtration products includes the sale of our XCell ATF systems and consumables, KrosFlo filtration products, SIUS filtration products, the silicone-molded products offered by EMT, which we acquired in the third quarter of 2020 and the products offered by NMS and ARTeSYN, which were both acquired during the fourth quarter of 2020. Revenue from protein products includes the sale of our Protein A ligands and cell culture growth factors. Revenue from our process analytics products includes the sale of our SoloVPE, FlowVPE and FlowVPX systems, consumables and service. Other revenue primarily consists of revenue from the sale of our operating room products to hospitals as well as freight revenue.

25

During the three months ended March 31, 2021, product revenue increased by $66.7 million, or 87.7%, as compared to the same period of 2020. The increase is due to the continued adoption of our products by our key bioprocessing customers, particularly our chromatography and filtration products. Beginning in the second quarter of 2020, we experienced an increase in overall sales as a result of accelerated demand, which was from broad-based covering mAb, gene therapy and COVID-19 customers working on vaccines and therapeutics. We expect there will be a continued increase in direct sales during 2021, especially from COVID-19 customers as they scale-up and move vaccine and therapy drug candidates through clinical trial processes. During the first quarter of 2021, we also saw good performance from our recent acquisitions, EMT, NMS and ARTeSYN, which were acquired in the second half of 2020. Revenue from these acquisitions represented $10.9 million, or 7.6%, of total revenue for the three months ended March 31, 2021. Additionally, we saw a $3.0 million increase in revenue related to our process analytics business associated with our acquisition of C Technologies, Inc. (“C Technologies”) in 2019, which was due to an increase in demand for our SoloVPE systems.

Royalty revenues

Royalty revenues in the three months ended March 31, 2021 and 2020 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 months ended March 31, 2021 and 2020 were comprised of the following:

	Three Months Ended March 31,				Increase/(Decrease)
	2021		2020		$ Change		% Change
	(Amounts in thousands, except for percentage data)
Cost of product revenue	$	59,747	$	31,982	$	27,765		86.8	%
Research and development		7,612		4,702		2,910		61.9	%
Selling, general and administrative		39,095		27,500		11,595		42.2	%
Total costs and operating expenses	$	106,454	$	64,184	$	42,270		65.9	%

Cost of product revenue

Cost of product revenue increased 86.8% in the three months ended March 31, 2021, compared to the same period of 2020, due primarily to the increase in product revenue mentioned above and costs associated with higher product volume. An increase in manufacturing headcount resulted in higher employee-related costs for the three months ended March 31, 2021, compared to the same period of 2020. Recent acquisitions during the second half of 2020, resulted in an increase in costs of product revenue during the three months ended March 31, 2021 for which there were no comparable amounts during 2020.

Gross margin was 58.2% in the three months ended March 31, 2021. The gross margin for the three months ended March 31, 2021 includes $1.6 million of amortization of inventory step-up associated with the ARTeSYN Acquisition. The gross margin for the three months ended March 31, 2020 was 58.0%. Excluding the step-up amortization, gross margin for the three months ended March 31, 2021 was 59.3%. The increase in gross margin, excluding the inventory step-up amortization, in the three months ended March 31, 2021, as compared to the same period of 2020, is due primarily to the increase in revenue mentioned above, and favorable product mix, partially offset by an increase in manufacturing headcount subsequent to March 31, 2020. Gross margins may fluctuate in future quarters based on expected 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.

26

R&D expenses increased 61.9% during the three months ended March 31, 2021, compared to the same period of 2020. The increase during the period is primarily due to the addition of $1.0 million of R&D expenses incurred by our recent ARTeSYN Acquisition for which there were not comparable costs in 2020, and due to the ramp up of project spending for new product development during the first quarter of 2021.    

We expect our R&D expenses for the remainder of 2021 to gradually increase 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 months ended March 31, 2021, SG&A costs increased by $11.6 million, or 42.2%, as compared to the same period of 2020. The increase is 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. Stock-based compensation expense and other employee-related costs increased during the three months ended March 31, 2021, as compared to the same period in 2020, resulting from an increase in headcount period over period. In addition, $3.2 million of the increase in SG&A costs for the three months ended March 31, 2021, was related to the 2020 acquisitions of EMT, NMS and ARTeSYN in the second half of 2020.

Other expenses, net

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

	Three Months Ended March 31,						Increase/(Decrease)
	2021			2020			$ Change			% Change
	(Amounts in thousands, except for percentage data)
Investment income	$	52		$	1,364		$	(1,312	)		(96.2	%)
Interest expense		(3,106	)		(2,976	)		(130	)		4.4	%
Other expenses		(224	)		382			(606	)		(158.6	%)
Total other expense, net	$	(3,278	)	$	(1,230	)	$	(2,048	)		166.5	%

Investment income

Investment income includes income earned on invested cash balances. The decrease of $1.3 million in 2021, as compared to the same period of 2020, was attributable to a decrease in interest rates on our invested cash balances. In March 2020, in response to the outbreak of COVID-19 and to stay ahead of disruptions and economic slowdown, the Federal Reserve reduced federal funds rates to a range of 0.0% to 0.25%, which will continue to affect our investment income in future periods. 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 months ended March 31, 2021 and 2020 is primarily from our 0.375% Convertible Senior Notes due 2024 (the “2019 Notes”), which were issued in July 2019. Interest expense increased $0.1 million for the three months ended March 30, 2021, as compared to the same periods in 2020.

The amortization of debt issuance costs on the 2019 Notes was $2.8 million for the three months ended March 31, 2021. Amortization of debt issuance costs on the 2019 Notes was $2.7 million for the three months ended March 31, 2020.    

Contractual coupon interest incurred on the 2019 Notes for the three months ended March 31, 2021 and 2020 was $0.3 million for both periods.

27

Other expenses

The change in other expenses, net during the three months ended March 31, 2021, compared to the same period of 2020, is primarily attributable to realized foreign currency losses related to amounts due from non-Swedish krona-based customers and vendors.

Income tax provision

Income tax provision for the three months ended March 31, 2021 and 2020 was as follows:

	Three Months Ended March 31,						Increase/(Decrease)
	2021			2020			$ Change		% Change
	(Amounts in thousands, except for percentage data)
Income tax provision	$	3,655		$	861		$	2,794		324.5	%
Effective tax rate		11.0	%		8.1	%

For the three months ended March 31, 2021, we recorded an income tax provision of $3.7 million. The effective tax rate was 11.0% for the three months ended March 31, 2021 and is based upon the estimated income for the year ending December 31, 2021 and the composition of income in different jurisdictions. The effective tax rate for the three months ended March 31, 2021 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 months ended March 31, 2020, we recorded an income tax provision of $0.9 million. The effective tax rate was 8.1% for the three months ended March 31, 2020 and is based upon the estimated income for the year ending December 31, 2020 and the composition of income in different jurisdictions. The effective tax rate for the three months ended March 31, 2020 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 acquisition and integration costs, intangible amortization and inventory step-up charges 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 months ended March 31, 2021 and 2020:

	Three Months Ended March 31,
	2021		2020

Intangible amortization		5,162		3,878
Non-GAAP adjusted income from operations	$	45,694	$	18,337

28

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 and the tax effects of these items. The following are reconciliations of net income in accordance with GAAP to non-GAAP adjusted net income for the three months ended March 31, 2021 and 2020:

Liquidity and Capital Resources

We have financed our operations primarily through revenues derived from product sales, the issuance of the 2019 Notes (defined below) 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.

29

At March 31, 2021, we had cash and cash equivalents (excluding restricted cash) of $711.3 million compared to cash and cash equivalents (excluding restricted cash) of $717.3 million at December 31, 2020.

On December 8, 2020, the Company completed a public offering in which 1,725,000 shares of its common stock, including the underwriters’ full exercise of an option to purchase up to an additional 225,000 shares, were sold to the public at a price of $181.00 per share. The total proceeds received by the Company from this offering, net of underwriting discounts and commissions and other estimated offering expenses payable by the Company, were approximately $297.8 million.

In 2020, we acquired three companies for an aggregate of $175.0 million in cash, net of cash acquired.

During the first quarter of 2021, the closing price of the Company’s common stock exceeded 130% of the conversion price of the 2019 Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the 2019 Notes are convertible at the option of the holders of the 2019 Notes during the second quarter of 2021, the quarter immediately following the quarter when the conditions are met, per the First Supplemental Indenture underlying the 2019 Notes. These conditions were met during the fourth quarter of 2020 as well and as a result, the Company received notices from note holders that they would convert $5,000 aggregate principal amount of the 2019 Notes, of which $1,000 principal were settled during the first quarter. The conversion resulted in the issuance of a nominal number of shares of the Company’s common stock to the holder, and the Company recorded a loss of less than $1,000 on the conversion of these notes, which is included in other (expenses) income on our consolidated statements of comprehensive income for the three months ended March 31, 2021. The 2019 Notes have a face value of $287.5 million and a carrying value and a carrying value of $246.6 million and continue to be classified as current liabilities on the Company’s consolidated balance sheet as of March 31, 2021.

We intend to use the net proceeds from the Offerings for working capital and other general corporate purposes, including to fund possible acquisitions of, or investments in, complementary businesses, products, services and technologies, such as the acquisitions executed in 2020 as mentioned in Note 3, “Acquisitions,” included in this report. It is the Company’s policy and intent to settle the face value of the 2019 Notes in cash and any excess conversion premium in shares of our common stock.

In July 2020, the Company entered into a First Amendment to the lease agreement for its Marlborough, Massachusetts facility, expanding the leased space by 66,939 square feet. In December 2020, the Company signed the Second Amendment to the lease agreement, changing the commencement date from April 1, 2021 to January 1, 2021. As a result, under the amended lease agreement, the Company will pay an additional $5.7 million in base rent over the life of the lease, which expires on November 30, 2028.

Operating activities

For the three months ended March 31, 2021, our operating activities provided cash of $9.3 million reflecting net income of $29.5 million and non-cash charges totaling $20.2 million primarily related to depreciation, amortization, deferred income taxes, amortization of debt discount and issuance costs, and stock-based compensation charges. An increase in accounts receivable consumed $19.8 million of cash and was primarily driven by the 87.7% year-to-date increase in revenues. An increase in inventory manufactured of $17.0 million supports expected increases in future revenue. An increase in accounts payable of $3.7 million was primarily due to increased inventory purchases to support customer orders. These are offset by a $4.9 million decrease in accrued liabilities primarily related to payment of employee bonuses during the three months ended March 31, 2021 and related to a decrease in deferred revenue related to products shipped during the first quarter of 2021. The remaining cash used in operating activities resulted from unfavorable changes in various other working capital accounts.

30  

For the three months ended March 31, 2020, our operating activities provided cash of $9.5 million reflecting net income of $9.8 million and non-cash charges totaling $13.4 million primarily related to depreciation, amortization, amortization of debt discount and issuance costs and stock-based compensation charges. An increase in accounts receivable consumed $2.4 million of cash and was primarily driven by the 25.5% year-to-date increase in revenues. An increase in inventory consumed $7.2 million to support future revenue, as well as inventory acquired in the C Technologies acquisition in 2019. A decrease in accounts payable and accrued liabilities of $5.7 million was due to the accrued liabilities acquired in the C Technologies acquisition in 2019, the timing of payments of payables, payment of the 2019 incentive compensation programs and an adjustment to the tax liability for the quarter. The remaining cash used in operating activities resulted from unfavorable changes in various other working capital accounts.

Investing activities

Our investing activities consumed $9.0 million of cash during the three months ended March 31, 2021, primarily related to the ongoing capital expenditures as we continue to increase our manufacturing capacity worldwide. Of these expenditures, $1.5 million represented capitalized costs related to our internal-use software.    

Capital expenditures for the three months ended March 31, 2020 included $0.9 million for capitalized costs related to our internal-use software.    

Financing activities

Cash provided by financing activities of $0.5 million for the three months ended March 31, 2021 included proceeds from stock option exercises during the period. Proceeds from stock option exercises during the three months ended March 31, 2020 were $1.6 million.

Working capital increased by approximately $29.6 million to $613.0 million at March 31, 2021 from $583.4 million at December 31, 2020 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;

• our ability to acquire additional bioprocessing products;

• the scope of and progress made in our R&D activities;

• 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 licensing or acquiring complementary 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

31  

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.

Off-Balance Sheet Arrangements

We do not have any special purpose entities or off-balance sheet financing arrangements as of March 31, 2021.

Net Operating Loss Carryforwards

At December 31, 2020, we had net operating loss carryforwards of $6.4 million remaining. We had business tax credits carryforwards of $9.4 million available to reduce future federal income taxes, if any. The business tax credits carryforwards will continue to expire at various dates through December 2039. 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.

Cautionary Statement Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements which are made pursuant to the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The forward-looking statements in this Quarterly Report on Form 10-Q do not constitute guarantees of future performance. Investors are cautioned that statements in this Quarterly Report on Form 10-Q which are not strictly historical statements, including, without limitation, express or implied statements or guidance regarding current or future financial performance and position, potential impairment of future earnings, management’s strategy, plans and objectives for future 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 impact of, and response to, the COVID-19 coronavirus pandemic and the related downturn of the U.S. and global economies 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 ultimate impact of the coronavirus pandemic on our business or financial results; the success of current and future collaborative or supply relationships, including our agreements with Cytiva (formerly GE Healthcare), MilliporeSigma and Purolite; 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 limited manufacturing capabilities and our dependence on third-party manufacturers and value-added resellers; the effect of the pandemic of the novel coronavirus disease, including

32  

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 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 QUALITATIVE 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 March 31, 2021. As a result, a hypothetical 100 basis point increase in interest rates would have no effect on our cash position as of March 31, 2021.

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.

ITEM 4. CONTROLS AND 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 Securities Exchange Act Rule 13a-15 or Rule 15d-15 that occurred in the three months ended March 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

33  

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. We are not currently aware of any such proceedings or claims that we believe will have, individually or in the aggregate, a material 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, 2020 and in subsequent filings, could cause our actual results to differ materially from those in the forward-looking statements. There are no material changes to the risk factors described in our Form 10-K for the period ended December 31, 2020.

Summary of Significant Accounting Policies

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 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, 2020 (“Form 10-K”), which was filed with the SEC on February 24, 2021.

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 (“COVID-19”) pandemic 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. (“C Technologies”), Engineered Molding Technology LLC (“EMT”), Non-Metallic Solutions, Inc. (“NMS”), ARTeSYN Biosolutions Holdings Ireland Limited (“ARTeSYN”) and Repligen Singapore Pte. Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation.

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 Accounting Standards Updates (“ASUs” or “ASU”) 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 Standard Updates – Not Yet Adopted

In August 2020, the Financial Accounting Standards Board (“FASB”) issued 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).” 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. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. ASU 2020-06 is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. This update permits the use of either the modified retrospective or fully retrospective method of transition. The Company is currently evaluating the timing and impact of the adoption of ASU 2020-06 on the Company’s consolidated financial statements.

Fair Value Measurements

Fair Value Measurements

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.

As of March 31, 2021 and December 31, 2020, cash and cash equivalents on the Company’s consolidated balance sheets included $544.1 million and $549.0 million, respectively, in a money market account. These funds are valued on a recurring basis using Level 1 inputs.

In July 2019, the Company issued $287.5 million aggregate principal amount of the Company’s 0.375% Convertible Senior Notes due July 15, 2024 (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 March 31, 2021 and December 31, 2020, the carrying value of the 2019 Notes was $246.6 million and $243.7 million, respectively, net of unamortized discount, and the fair value of the 2019 Notes was $502.0 million and $501.0 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 March 31, 2021. The 2019 Notes are discussed in more detail in Note 12, “Convertible Senior Notes” to Part II, Item 8, “Financial Statements and Supplementary Data” to our Form 10-K.

During the three months ended March 31, 2021, there were no remeasurements to fair value of financial assets and liabilities that are not measured at fair value on a recurring basis.

3. Acquisitions

ARTeSYN Biosolutions Holdings Ireland Limited

On October 27, 2020, the Company entered into an Equity and Asset Purchase Agreement with ARTeSYN, a company organized under the laws of Ireland, Third Creek Holdings, LLC, a Nevada limited liability company (“Third Creek”), Alphinity, LLC, a Nevada limited liability company (“Alphinity”, and together with Third Creek the “ARTeSYN Sellers”), and Michael Gagne, solely in his capacity as the representative of the ARTeSYN Sellers, pursuant to which the Company acquired (i) all of the outstanding equity securities of ARTeSYN and (ii) certain assets from Alphinity related to the business of ARTeSYN (collectively, the “ARTeSYN Acquisition”) for approximately $200 million, comprised of approximately $130 million in cash to the ARTeSYN Sellers and approximately $70 million in the Company’s common stock to Third Creek. The transaction closed on December 3, 2020.

ARTeSYN is headquartered in Waterford, Ireland and conducts its operations in Ireland, the United States and Estonia. Its suite of single-use solutions has been created with the goal of enabling “abundance in medicine” by allowing 10x greater efficiency in biologics manufacturing. The ARTeSYN team has created a number of solutions targeting the single-use space from single-use valves with fully disposable valve liners, XO® skeletal supports, a hybrid small parts offering for de-bottlenecking traditional facilities, and fully automated SU process systems that have quickly become leading solutions in the bioprocessing industry. In addition to its single-use solutions, ARTeSYN also engages in the manufacture of large-scale systems to be used for biologics manufacturing. ARTeSYN has established downstream processing leadership with a suite of state of the art single-use systems for chromatography, filtration, continuous manufacturing and media/buffer prep workflows. In addition, the Company has integrated unique flow path assemblies utilizing EMT’s silicone extrusion and molding technology, to deliver highly differentiated, low hold-up volume systems that minimize product loss during processing.

Consideration Transferred

The ARTeSYN Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations”. The ARTeSYN Acquisition was funded through payment of $130.7 million in cash, as well as issuance of 372,990 unregistered shares of the Company’s common stock totaling $69.4 million, contingent consideration of approximately $1.5 million, and settlement of preexisting invoices with the Company of approximately $2.3 million, for a total purchase price of $204.0 million. Under the acquisition method of accounting, the assets acquired and liabilities assumed of ARTeSYN 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 tangible assets acquired is estimated to be $7.9 million, the fair value of the intangible assets acquired is estimated to be $67.4 million, and the residual goodwill is estimated to be $128.7 million. The estimated consideration and preliminary purchase price information has been prepared using a preliminary valuation. Payment of the final consideration for working capital was made in April 2021.

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	$	130,713
Equity consideration		69,422
Contingent consideration		1,548
Settlement of preexisting liabilities		2,310
Fair value of net assets acquired	$	203,993

Acquisition related costs are not included as a component of consideration transferred but are expensed in the periods in which the costs are incurred. The Company incurred $4.0 million in transaction and integration costs associated with the ARTeSYN Acquisition in 2020 and an additional $0.5 million of transaction and integration costs during the first quarter of 2021. The transaction costs are included in selling, general and administrative (“SG&A”) expenses in the consolidated statements of comprehensive income. 

The consideration transferred includes approximately $1.5 million related to consideration that was deferred at the acquisition date, with payment to the ARTeSYN Sellers contingent upon recognizing revenue on a large-scale system within 120 days of the acquisition date. This consideration is recorded at its estimated fair value as of the acquisition date, which includes the assumption of high probability of such revenue being recognized. During the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to 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 are recorded to our consolidated statements of comprehensive income. 

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 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 December 3, 2020). Any such revision or changes may be material. The final allocation may include changes to: (1) deferred revenue; (2) inventory; (3) deferred tax liabilities, net; (4) allocations to intangible assets such as tradenames, developed technology and customer relationships as well as goodwill; and (5) other assets and liabilities. In March 2021, the Company recorded a $0.1 million working capital adjustment related to settlement of a pre-acquisition liability, which offset goodwill in the table below.

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

Cash and cash equivalents	$	2,982
Accounts receivable		4,811
Inventory		8,592
Prepaid expenses and other current assets		5,561
Property and equipment		1,836
Operating lease right of use asset		1,611
Other noncurrent assets		26
Customer relationships		38,400

Operating lease liability		(417	)
Operating lease liability, long-term		(1,193	)
Fair value of net assets acquired	$	203,993

Acquired Goodwill

The goodwill of $128.7 million represents future economic benefits expected to arise from synergies from combining operations and commercial organizations to increase market presence and the extension of existing customer relationships. 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 ARTeSYN Acquisition and their estimated useful lives:

	Useful life		Fair Value
			(Amounts in thousands)
Customer relationships		17 years	$	38,400
Developed technology		15 years		27,060
Trademark and tradename		21 years		1,630
Non-competition agreements		3 years		300

Non-Metallic Solutions, Inc.

On October 15, 2020, the Company entered into a Stock Purchase Agreement with NMS, a Massachusetts corporation, and each of William Malloneé and Derek Masser, the legal and beneficial owners of NMS, to purchase NMS, which transaction subsequently closed on October 20, 2020 (the “NMS Acquisition”).

NMS, headquartered in Auburn, Massachusetts, is a manufacturer of fabricated plastics, custom containers, and related assemblies and components used in the manufacturing of biologic drugs. The acquisition of NMS allows Repligen to expand its line of single-use systems and associated integrated flow path assemblies, streamline the supply chain for current products, and gives the Company more flexibility to scale and expand single-use and systems portfolios.

Consideration Transferred

The NMS Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations.” Total consideration paid was $16.1 million, which included $1.3 million deposited into an escrow account against which the Company may make claims for indemnification. The fair value of the net tangible assets acquired is estimated to be approximately $0.9 million, the fair value of the intangible assets acquired is estimated to be $8.5 million, and the residual goodwill is estimated to be approximately $6.7 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 incurred $0.2 million of transaction and integration costs associated with the NMS Acquisition in 2020 and $0.2 million in 2021. The transaction costs are included in SG&A expenses in the consolidated statements of comprehensive income. 

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 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 October 20, 2020).

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

Cash and cash equivalents	$	1,163
Accounts receivable		415
Inventory		334
Prepaid expenses and other current assets		13
Property and equipment		73
Operating lease right of use asset		194

Fair value of net assets acquired	$	16,099

Acquired Goodwill

The goodwill of $6.7 million represents future economic benefits expected to arise from anticipated synergies from the integration of NMS. These synergies include certain cost savings, operating efficiencies and other strategic benefits projected to be achieved as a result of the NMS Acquisition. Substantially all of the goodwill recorded is expected to be deductible for income tax purposes. In February 2021, the Company recorded an adjustment to goodwill of $0.1 million related to the finalization of the working capital true-up.

Engineered Molding Technology LLC

On July 13, 2020, the Company completed the acquisition of 100% of the membership interests of EMT, a New York limited liability company, pursuant to a Membership Interest Purchase Agreement, dated June 26, 2020, by and among the Company, EMT, and each of Michael Pandori and Todd Etesse, the legal and beneficial owners of EMT (such acquisition, the “EMT Acquisition”).

EMT, headquartered in Clifton Park, New York, is an innovator and manufacturer of single-use silicone assemblies and components used in the manufacturing of biologic drugs. EMT’s standard and custom molding as well as their over-molded connectors and silicone tubing products are key components in single-use filtration and chromatography systems. EMT’s products will complement and expand Repligen’s single-use product offerings.

Consideration Transferred

The EMT Acquisition was accounted for as a purchase of a business under ASC 805, “Business Combinations”. Total consideration paid was $28.5 million, which included $2.2 million deposited into an escrow account against which the Company may make claims for indemnification. Under the acquisition method of accounting, the net assets of EMT were recorded as of the acquisition date, at their respective fair values, and consolidated with those of Repligen. The fair value of the net tangible assets acquired is approximately $1.5 million, the fair value of the intangible assets acquired is approximately $14.4 million, and the residual goodwill is approximately $12.6  million. The estimated consideration and preliminary purchase price information have been prepared using a preliminary valuation. 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 Repligen believes to be reasonable. 

Acquisition-related costs are not included as a component of consideration transferred but are expensed in the periods in which the costs are incurred. The Company incurred $1.2  million of transaction and integration related costs associated with the EMT Acquisition in 2020 and  $0.1 million during the first quarter of 2021. The transaction costs are included in SG&A expenses in the consolidated statements of comprehensive income. 

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 preliminary valuation. The Company obtained this information during due diligence and through other sources. In the months after the closing, the Company obtained additional information about these assets and liabilities as it learned more about EMT. The Company refined the estimates of fair value to more accurately allocate the purchase price. Only items identified as of the acquisition date were considered for subsequent adjustment. We have made appropriate adjustments to the purchase price allocation during the measurement period, which ends on July 13, 2021. We consider these adjustments to be final. The components and allocation of the purchase price consist of the following (amounts in thousands):

Cash and cash equivalents	$	69
Accounts receivable		1,057
Inventory		449
Prepaid expenses and other current assets		7
Property and equipment		414

Acquired Goodwill

The goodwill of $12.6 million represents future economic benefits expected to arise from anticipated synergies from the integration of EMT. These synergies include certain cost savings, operating efficiencies and other strategic benefits projected to be achieved as a result of the EMT Acquisition. Substantially all of the goodwill recorded is expected to be deductible for income tax purposes.

Accounting Policies [Abstract]

Revenue Recognition

4. 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 months ended March 31, 2021 and 2020 were as follows:

	Three Months Ended
	March 31,
	2021		2020
	(Amounts in thousands)
Product revenue	$	142,737	$	76,060
Royalty and other income		100		30
Total revenue	$	142,837	$	76,090

When disaggregating revenue, the Company considered all of the economic factors that may affect its revenues. Because 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, factors such as regulatory and geopolitical factors within those regions could impact the nature, timing and uncertainty of the Company’s revenues and cash flows. In addition, a significant portion of the Company’s revenues are 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 can be found in Note 14, “Segment Reporting,” included in this report.

Except for the $10.9 million of revenue with MilliporeSigma for the three months ended March 31, 2020, there were no significant customers that represented 10% or more of total revenue for the periods presented in the table above.

For more information regarding our product revenue, see Note 5, “Revenue Recognition” included in Part II, Item 8, “Financial Statements and Supplementary Data” to our Form 10-K, which was filed with the SEC on February 24, 2021.

Contract Balances from Contracts with Customers

The following table provides information about receivables and deferred revenue from contracts with customers as of March 31, 2021 (amounts in thousands):

	2021
Balances from contracts with customers only:
Accounts receivable	$	90,207
Deferred revenue (included in accrued liabilities in the consolidated balance sheets)	$	14,253
Revenue recognized during the three-month period ended March 31, 2021 relating to:
The beginning deferred revenue balance	$	8,525
Changes in pricing related to products or services satisfied in previous periods	$	—

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.

Goodwill and Intangible Assets

5. Goodwill and Intangible Assets

Goodwill

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 three months ended March 31, 2021 (amounts in thousands):

Balance at December 31, 2020	$	618,305
Measurement period adjustment - NMS		(71	)
Measurement period adjustment - ARTeSYN		90
Cumulative translation adjustment		(807	)
Balance at March 31, 2021	$	617,517

During each of the fourth quarters of 2020, 2019 and 2018, 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 months ended March 31, 2021.

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 SG&A 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 our 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 March 31, 2021.

Indefinite-lived 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

3 Months Ended

Convertible Senior Notes

7. Convertible Senior Notes

0.375% Convertible Senior Notes due 2024

On July 19, 2019, the Company issued $287.5 million aggregate principal pursuant to the 2019 Notes, which includes the underwriters’ exercise in full of an option to purchase an additional $37.5 million aggregate principal amount of 2019 Notes (the “Notes Offering”). The net proceeds of the Notes Offering, after deducting underwriting discounts and commissions and other related offering expenses payable by the Company, were approximately $278.5 million. The 2019 Notes are senior, unsecured obligations of the Company, and bear interest at a rate of 0.375% per year. Interest is payable semi-annually in arrears on January 15 and July 15 of each year, beginning on January 15, 2020. The 2019 Notes will mature on July 15, 2024, unless earlier repurchased or converted in accordance with their terms.

During the first quarter of 2021, the closing price of the Company’s common stock exceeded 130% of the conversion price of the 2019 Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the 2019 Notes are convertible at the option of the holders of the 2019 Notes during the second quarter of 2021, the quarter immediately following the quarter when the conditions are met, as stated in the terms of the 2019 Notes. These conditions were also met during the fourth quarter of 2020 and as a result, the Company received notices from note holders that they would convert $5,000 aggregate principal amount of the 2019 Notes, of which $1,000 principal were settled during the first quarter of 2021. The conversion resulted in the issuance of a nominal number of shares of the Company’s common stock to the note holders, and the Company recorded a loss of approximately  $1,000 on the conversion of these notes, which is included in other (expenses) income on our consolidated statements of comprehensive income for the three months ended March 31, 2021. The Company continues to classify the carrying value of the 2019 Notes as current liabilities on the Company’s consolidated balance sheet at March 31, 2021.

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

	March 31,			December 31,
	2021			2020
	(Amounts in thousands)
0.375% Convertible Senior Notes due 2024:
Principal amount	$	287,499		$	287,500
Unamortized debt discount		(35,843	)		(38,317	)
Unamortized debt issuance costs		(5,095	)		(5,446	)
Net carrying amount	$	246,561		$	243,737

Interest expense recognized on the 2019 Notes for the three months ended March 31, 2021 was $0.3 million, $2.5 million and $0.4 million for the contractual coupon interest, the accretion of the debt discount and the amortization of the debt issuance costs, respectively. The effective interest rate on the 2019 Notes is 5.1%, which included the interest on the 2019 Notes, amortization of the debt discount and debt issuance costs. At March 31, 2021 and December 31, 2020, the carrying value of the 2019 Notes was $246.6 million and $243.7 million, respectively, net of unamortized discount, and the fair value of the 2019 Notes was $502.0 million and $501.0 million, respectively. The fair value of the 2019 Notes was determined based on the most recent trade activity of the 2019 Notes at March 31, 2021.

8. Stockholders’ Equity

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 plans. The shares of common stock underlying any awards under the 2018 Plan and previous 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 March 31, 2021, 2,179,921 shares were available for future grants under the 2018 Plan.

Stock-Based Compensation

For the three months ended March 31, 2021 and 2020, the Company recorded stock-based compensation expense of $6.5 million and $4.2 million, respectively, for share-based awards granted under the Plans. The following table presents stock-based compensation expense in the Company’s consolidated statements of comprehensive income:

	Three Months Ended March 31,
	2021		2020
	(Amounts in thousands)
Cost of product revenue	$	506	$	433
Research and development		716		372
Selling, general and administrative		5,319		3,360
Total stock-based compensation	$	6,541	$	4,165

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 consisting 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 March 31, 2021, options to purchase 697,118 shares and 654,250 stock units were outstanding under the Plans.

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 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. Prior to 2020, the Company issued performance stock units to certain employees which are tied to the achievement of certain Company financial goal metrics and the passage of time. During 2020, the Company implemented a formal program that issued performance stock units to certain employees set to vest upon the achievement of individual goals and the passage of time. The Company recognizes expense on performance-based awards over the vesting period based on the probability that the performance metrics will be achieved. 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.

Information regarding option activity for the three months ended March 31, 2021 under the Plans is summarized below:

	Shares			Weighted average exercise price		Weighted- Average Remaining Contractual Term (in Years)		Aggregate Intrinsic Value (in Thousands)

(1) Represents the number of vested options as of March 31, 2021 plus the number of unvested options expected to vest as of March 31, 2021 based on the unvested outstanding options at March 31, 2021 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 March 31, 2021, the last business day of the first quarter of 2021, of $194.41 per share and the exercise price of each in-the-money option) that would have been received by the option holders had all option holders exercised their options on March 31, 2021. The aggregate intrinsic value of stock options exercised during the three months ended March 31, 2021 and 2020 was $2.5 million and $4.7 million, respectively.

The weighted average grant date fair value of options granted during the three months ended March 31, 2021 and 2020 was $92.35 and $41.77, respectively. The total fair value of stock options that vested during the three months ended March 31, 2021 and 2020 was $1.9 million and $2.0 million, respectively.

The fair value of stock units is calculated using the closing price of the Company’s common stock on the date of grant. Information regarding stock unit activity, which includes activity for RSUs and performance stock units, for the three months ended March 31, 2021 under the Plans is summarized below:

	Shares			Weighted- Average Remaining Contractual Term (in Years)		Aggregate Intrinsic Value (in  Thousands)

Unvested and expected to vest at March 31, 2021(1)		639,254			2.94	$	124,277

(1) Represents the number of vested stock units as of March 31, 2021 plus the number of unvested stock units expected to vest as of March 31, 2021 based on the unvested outstanding stock units at March 31, 2021 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 March 31, 2021, the last business day of the first quarter of 2021, of  $194.41 per share, as stock units do not have an exercise price) that would have been received by the stock unit holders had all holders exercised on March 31, 2021. The aggregate intrinsic value of stock units vested during the three months ended March 31, 2021 and 2020 was $27.1 million and $11.8 million, respectively.

The weighted average grant date fair value of stock units vested during the three months ended March 31, 2021 and 2020 was $209.13 and $86.75, respectively. The total fair value of stock units that vested during the three months ended March 31, 2021 and 2020 was $6.5 million and $5.3 million, respectively.

As of March 31, 2021, there was $65.4 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 3.25 years. The Company expects 1,894,207 unvested options and stock units to vest over the next five years.

In June 2018, the Company secured an agreement with Navigo Proteins (“Navigo”) for the exclusive co-development of multiple affinity ligands for which Repligen holds commercialization rights. The Company is manufacturing and has agreed to supply the first of these ligands, NGL-Impact®, exclusively to Purolite Life Sciences (“Purolite”), who will pair 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.

For the three months ended March 31, 2021, we recorded an income tax provision of $3.7 million. The Company’s effective tax rate for the three months ended March 31, 2021 was 11%, compared to 8.1% for the corresponding period in the prior year. The effective tax rates for the three months ended March 31, 2021 and 2020 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.

On March 27, 2020, President Trump signed the $2.2 trillion bipartisan Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. The CARES Act, the third congressional bill to address COVID-19, provides for loans and other benefits to businesses, expanded unemployment insurance, direct payments to those with middle-income and below wages, new appropriations funding for healthcare and other priorities, and tax changes, including deferrals of employer payroll tax liabilities, coupled with an employee retention tax credit and rollbacks of TCJA limitations on net operating losses (“NOLs”) and the Section 163(j) business interest limitation and a TCJA technical correction on qualified improvement property. The Company evaluated the provisions of the CARES Act and no provision had a material effect on the Company’s financial position or results of operations.

The Company’s tax returns are subject to examination by federal, state and international tax authorities for the following periods:

Earnings Per Share

3 Months Ended

Mar. 31, 2021

Earnings Per Share

12. Earnings Per Share

The Company reports earnings per share in accordance with ASC 260, “Earnings Per Share,” which establishes standards for computing and presenting earnings per share. Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share 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. Under the treasury stock method, unexercised “in-the-money” stock options and warrants are assumed to be exercised at the beginning of the period or at issuance, if later. The assumed proceeds are then used to purchase common shares at the average market price during the period. In periods when the Company has a net loss, stock awards are excluded from the calculation of earnings per share as their inclusion would have an antidilutive effect.

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

	Three Months Ended March 31,
	2021		2020
	(Amounts in thousands, except per share data)
Net income	$	29,450	$	9,815
Weighted average shares used in computing net income per share - basic		54,805		52,139
Effect of dilutive shares:
Options and stock units		964		970
Convertible Senior Notes		1,092		—
Dilutive effect of unvested performance stock units		8		—
Dilutive potential common shares		2,064		970
Weighted average shares used in computing net income per share - diluted		56,869		53,109
Earnings per share:
Basic	$	0.54	$	0.19
Diluted	$	0.52	$	0.18

At March 31, 2021, there were outstanding options to purchase 697,118 shares of the Company’s common stock at a weighted average exercise price of $49.39 per share and 654,250 shares of common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three months ended March 31, 2021, 94,236 shares of the Company’s common stock were excluded from the calculation of diluted earnings per share 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 March 31, 2020, there were outstanding options to purchase 915,518 shares of the Company’s common stock at a weighted average exercise price of $32.91 per share and 716,630 common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three months ended March 31, 2020, 39,711 shares of the Company’s common stock were excluded from the calculation of diluted earnings per share 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, conversion of the 2019 Notes will be settled in cash, shares of the Company’s common stock or a combination thereof, at the Company’s election. As of March 31, 2021, the 2019 Notes were convertible. The Company currently intends to settle the par value of the 2019 Notes in cash and any excess conversion premium in shares.

As provided by the terms of the indenture underlying the 2019 Notes, the Company has a choice to settle the conversion obligation for the 2019 Notes in cash, shares or any combination of the two. The Company currently intends to settle the par value of the 2019 Notes in cash and any excess conversion premium in shares. The Company applies the provisions of ASC 260, “Earnings Per Share”, Subsection 10-45-44, to determine the diluted weighted average shares outstanding as it relates to the conversion spread on its convertible notes. Accordingly, the par value of the 2019 Notes is not included in the calculation of diluted income per share, but the dilutive effect of the conversion premium is considered in the calculation of diluted net income per share using the treasury stock method. The dilutive impact of the 2019 Notes is based on the difference between the Company’s current period average stock price and the conversion price of the 2019 Notes, provided there is a premium. Pursuant to this accounting standard, there is no dilution from the accreted principal of the 2019 Notes. For the three months ended March 31, 2021, the dilutive effect of the conversion premium included in the calculation of diluted earnings was 1,091,776 shares. There was no dilutive effect of the conversion premium included in the calculation of diluted earnings per share for the three months ended March 31, 2020.

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 March 31, 2021 and December 31, 2020, 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.

No revenue from customers represented 10% or more of the Company’s total revenue for the three months ended March 31, 2021. Revenue from MilliporeSigma represented 14% of the Company’s total revenue for the three months ended March 31, 2020.

Basis of presentation

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 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, 2020 (“Form 10-K”), which was filed with the SEC on February 24, 2021.

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 (“COVID-19”) pandemic 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. (“C Technologies”), Engineered Molding Technology LLC (“EMT”), Non-Metallic Solutions, Inc. (“NMS”), ARTeSYN Biosolutions Holdings Ireland Limited (“ARTeSYN”) and Repligen Singapore Pte. Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation.

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

Recent Accounting Standards Updates

We consider the applicability and impact of all Accounting Standards Updates (“ASUs” or “ASU”) 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 Standard Updates – Not Yet Adopted

In August 2020, the Financial Accounting Standards Board (“FASB”) issued 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).” 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. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. ASU 2020-06 is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. This update permits the use of either the modified retrospective or fully retrospective method of transition. The Company is currently evaluating the timing and impact of the adoption of ASU 2020-06 on the Company’s consolidated financial statements.
