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.~~2021 (“Form

10-K”).

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The business and economic uncertainty resulting from the novel coronavirus

(“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—Debt with Conversion and Other Options (Subtopic

470-20)

and Derivatives and ~~Hedging -~~ 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,~~June 30, 2021 and December 31, 2020, cash and cash equivalents on the Company’s consolidated balance sheets included ~~$544.1~~$483.9 million and $549.0 million, respectively, in a money market ~~account.~~accounts. 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,~~June 30, 2021 and December 31, 2020, the carrying value of the 2019 Notes was ~~$246.6~~$249.4 million and $243.7 million, respectively, net of unamortized discount, and the fair value of the 2019 Notes was ~~$502.0~~$496.7 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,~~June 30, 2021.

The 2019 Notes are discussed in more detail in Note 12,

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.

hold-up

volume systems that minimize product loss during processing. The ARTeSYN portfolio expands on the market success of the Company’s hollow fiber systems and complements our chromatography and TFF filtration product lines.

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~~ $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~~

.Company. The fair value of the net tangible assets acquired is estimated to be ~~$7.9~~$8.0 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~~

$128.6 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 infrom the date of acquisition to December 31, 2020, and an additional

~~0.5~~

$2.0 million of transaction and integration costs during the first ~~quarter~~half 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~~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.

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.

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.

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~~. The following table represents the change in the carrying value of goodwill for the ~~three~~six months ended ~~March 31,~~June 30, 2021 (amounts in thousands):


Balance at December 31, 2020	$	618,305		$	618,305
Measurement period adjustment - NMS		(71	)		(71	)

Balance at March 31, 2021	$	617,517
Balance at June 30, 2021				$	617,593

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 and six months ended ~~March 31,~~June 30, 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 expenses in the Company’s statements of comprehensive income. Intangible assets and their related useful lives are reviewed at least annually to determine if any adverse conditions existed that would indicate the carrying value of these assets may not be recoverable. More frequent impairment assessments are conducted if certain conditions exist, including a change in the competitive landscape, any internal decisions to pursue new or different technology strategies, a loss of a significant customer, or a significant change in the marketplace, including changes in the prices paid for 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,~~June 30, 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.

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.

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,~~June 30, 2021, ~~2,179,921~~2,159,922 shares were available for future ~~grant~~

grants under the 2018 Plan.

Stock-Based Compensation

For each of the three months ended ~~March 31,~~June 30, 2021 and 2020, the Company recorded stock-based compensation expense of ~~$6.5~~$7.1 million and ~~$4.2~~$4.1 million, respectively, for share-based awards granted under the Plans. For the six months ended June 30, 2021 and 2020, the Company recorded stock-based compensation expense of $13.7 million and $8.3 million, respectively.

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,~~June 30, 2021, options to purchase ~~697,118~~682,913 shares and ~~654,250~~618,618 stock units were outstanding under the Plans.

~~Table of Contents~~

The Company uses the B

~~ack-Scholes~~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~~Since 2020, the Company has implemented a formal ~~program~~programs that ~~issued~~issue performance stock units to certain employees set to vest upon the achievement of individual goals and financial goals of the Company, as well as 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.

11.	Income Taxes

For the three and six months ended ~~March 31,~~June 30, 2021,

we recorded an income tax provision of ~~$3.7 million.~~$8.1 million and $11.8 million, respectively. The Company’s effective tax rate for the three and six months ended ~~March 31,~~June 30, 2021 was ~~11%~~18.3% and 15.2%, respectively, compared to ~~8.1%~~1.0% and 3.8% for the corresponding ~~period~~periods in the prior year.

The increase in effective tax rates was primarily due to higher income before income taxes, lower windfall benefits recognized on stock option exercises and the vesting of stock units partially offset by lower U.S. taxation of foreign earnings.

The effective tax rates for the three and six months ended ~~March 31,~~June 30, 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.

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.

At ~~March 31,~~June 30, 2021, there were outstanding options to purchase ~~697,118~~682,913 shares of the Company’s common stock at a weighted average exercise price of ~~$49.39~~$51.71 per share and ~~654,250~~618,618 shares of common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three and six months ended ~~March 31,~~June 30, 2021, ~~94,236~~69,388 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,~~June 30, 2020, there were outstanding options to purchase ~~915,518~~768,904 shares of the Company’s common stock at a weighted average exercise price of ~~$32.91~~$38.87 per share and ~~716,630~~696,098 shares of common stock issuable upon the vesting of stock units, which include RSUs and performance stock units. For the three and six months ended ~~March 31,~~June 30, 2020, ~~39,711~~11,578 and 12,328 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,~~June 30, 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 and six months ended ~~March 31,~~June 30, 2021, the dilutive effect of the conversion premium included in the calculation of diluted earnings was

~~1,091,776 shares.~~ 1,011,993 shares and 1,052,337 shares, respectively. There was 0 dilutive effect of the conversion premium included in the calculation of diluted earnings per share for the three and six months ended ~~March 31,~~June 30, 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.~~gene therapy and monoclonal antibody manufacturing.

Royalty revenues

Royalty revenues in the three and six months ended ~~March 31,~~June 30, 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 and six months ended ~~March 31,~~June 30, 2021 and 2020 were comprised of the following:

Cost of product revenue

Cost of product revenue increased ~~86.8%~~68.2% and 76.8% in the three and six months ended ~~March 31,~~June 30, 2021, compared to the same ~~period~~periods of 2020, due primarily to the increase in product revenue mentioned above and costs associated with higher product volume. AnIn addition, there was an increase in manufacturing headcount for the three and six months ended June 30, 2021, as compared to the same periods of 2020, which resulted in higher employee-related ~~costs for the three months ended March 31, 2021, compared to the same period of 2020. Recent~~costs. We completed acquisitions during the second half of 2020, which resulted in an increase in costs of product revenue during ~~the three months ended March 31,~~these periods in 2021 as well, for which there were no comparable amounts during 2020.

Gross margin was ~~58.2%~~62.0% and 60.2% in the three and six months ended ~~March 31,~~June 30, 2021. The gross margin for the ~~three~~six months ended ~~March 31,~~June 30, 2021 includes $1.6 million of amortization of inventory

step-up

associated with the ARTeSYN Acquisition. The gross margin for the ~~three~~six months ended ~~March 31,~~June 30, 2020 was ~~58.0%~~57.9%. Excluding the

step-up

amortization, gross margin for the ~~three~~six months ended ~~March 31,~~June 30, 2021 was ~~59.3%~~60.7%. The increase in gross margin, excluding the inventory

step-up

amortization, in the ~~three~~six months ended ~~March 31,~~June 30, 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,~~June 30, 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.

~~Table of Contents~~

R&D expenses increased ~~61.9%~~93.5% during the three months ended ~~March 31,~~June 30, 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~~during the period, for which there were not comparable costs in 2020, and due to the increase in employee related costs as the number of R&D employees has increased since June 30, 2020.

R&D expenses increased 77.0% during the six months ended June 30, 2021, compared to the same period of 2020. The increase during the period is due to the addition of $2.1 million in R&D expenses related to ARTeSYN’s operations and increased costs associated with an increase in R&D headcount and the ramp up of project spending for new product development during the first ~~quarter~~half 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 and six months ended ~~March 31,~~June 30, 2021, SG&A costs increased by ~~$11.6~~$17.6 million, or ~~42.2%~~65.9%, and $29.2 million, or 53.9%, as compared to the same ~~period~~periods 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 and six months ended ~~March 31,~~June 30, 2021, as compared to the same period in 2020, resulting from an increase in headcount period over period. In addition, ~~$3.2~~$3.6 million and $6.8 million of the increase in SG&A costs for the three and six months ended ~~March 31,~~June 30, 2021, respectively, was related to the ~~2020 acquisitions~~addition of EMT, NMS and ARTeSYN induring the second half of 2020 for which there were no comparable amounts for the same periods of 2020.

Investment income

Investment income includes income earned on invested cash balances. The decrease of ~~$1.3~~$0.2 million and $1.5 million in the three and six months ended June 30, 2021, as compared to the same ~~period~~periods 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 and six months ended ~~March 31,~~June 30, 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, which includes the amortization of debt issuance costs and contractual coupon interest, increased $0.1 million and $0.3 million for the three and six months ended ~~March~~June 30, 2021, as compared to the same periods in 2020.

~~The amortization~~ This is a result of the decrease in the balance of debt issuance costs that are being amortized. As these costs decrease, the carrying value of the debt increases and interest calculated based on the ~~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.~~

27carrying value increases as well.

~~Table of Contents~~

Other expenses

The change in other expenses, net during the three and six months ended ~~March 31,~~June 30, 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 and six months ended ~~March 31,~~June 30, 2021 and 2020 was as follows:

Effective tax rate		18.3	%		1.0	%							15.2	%		3.8	%

For the three and six months ended ~~March 31,~~June 30, 2021, we recorded an income tax provision of ~~$3.7 million.~~$8.1 million and $11.8 million, respectively. The effective tax rate was ~~11.0%~~18.3% and 15.2% for the three and six months ended ~~March 31,~~June 30, 2021 and is based upon the estimated income for the year ending December 31, 2021 and the composition of income in different jurisdictions. The increase in effective tax rates was primarily due to higher income before income taxes, lower windfall benefits recognized on stock option exercises and the vesting of stock units, partially offset by lower U.S. taxation of foreign earnings. The effective tax rate for the three and six months ended ~~March 31,~~June 30, 2021 was lower than the U.S. statutory rate of 21% primarily due to business tax credits and windfall benefits on stock option exercises and the vesting of stock units. For the three and six months ended ~~March 31,~~June 30, 2020, we recorded an income tax provision of ~~$0.9 million.~~$0.2 million and $1.0 million, respectively. The effective tax rate was ~~8.1%~~1.0% and 3.8% for the three and six months ended ~~March 31,~~June 30, 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 and six months ended ~~March 31,~~June 30, 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.

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.~~offerings (the “Offerings”). Our revenue for the foreseeable future will primarily be limited to our bioprocessing product revenue.

~~Table of Contents~~

At ~~March 31,~~June 30, 2021, we had cash and cash equivalents (excluding restricted cash) of ~~$711.3~~$734.3 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~~second 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~~third 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 also met during the fourth quarter of 2020 ~~as well~~ and asthe first quarter of 2021. As a result, the Company received notices from note holders that they would convert ~~$5,000~~$6,000 aggregate principal amount of the 2019 Notes, of which $1,000 principal were settled during the first ~~quarter.~~quarter of 2021, $4,000 principal were settled during the second quarter of 2021 and $1,000 principal will be settled during the third quarter of 2021. The ~~conversion~~conversions 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~~approximately $4,000 on the conversion of these notes, which is included in other ~~(expenses) income~~expenses, net on our consolidated statements of comprehensive income for the three and six months ended ~~March 31,~~June 30, 2021. The 2019 Notes have a face value of $287.5 million and a carrying value and a carrying value of ~~$246.6~~$249.4 million and continue to be classified as current liabilities on the Company’s consolidated balance sheet as of ~~March 31,~~June 30, 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.

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

~~Table of Contents~~

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,~~June 30, 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.
