ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Information pertaining to fiscal year 2019 was included in the Company’s Annual Report on Form 10-K (“Form 10-K”) for the year ended December 31, 2020 on pages 39 through 57 under Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which was filed with the SEC on February 24, 2021.

Repligen and its subsidiaries, collectively doing business as Repligen Corporation (“Repligen”, “we”, “our”, or “the Company”) is a global life sciences company that develops and commercializes highly innovated bioprocessing technology and systems that increase efficiencies and flexibility in the process of manufacturing biological drugs.

As the overall market for biologics continues to grow and expand, our customers – primarily large biopharmaceutical companies and contract development and manufacturing organizations – face critical production cost, capacity, quality and time pressures. Built to address these concerns, our products help set new standards for the way biologics are manufactured. We are committed to inspiring advances in bioprocessing as a trusted partner in the production of critical biologic drugs – including monoclonal antibodies (“mAbs”), recombinant proteins, vaccines and cell and gene therapies ("C&GT") – that are improving human health worldwide. For more information regarding our business, products and acquisitions, see above sections in Part I entitled “Overview”, “Our Products”, “2021 Acquisitions”, “2020 Acquisitions”, “2019 Acquisition” and “Our Market Opportunity”.

COVID-19 Pandemic

Our global operations have been and continue to be affected by the ongoing global pandemic of a novel strain of coronavirus (“COVID-19”) and the resulting volatility and uncertainty it has caused in the United States and international markets. During the year ended December 31, 2021, many businesses and countries, including the United States, continued applying preventative and precautionary measures designed to mitigate the spread of the virus and its variants including government orders and other restrictions on the conduct of business operations.

In response to COVID-19, we enacted safety measures, including social distancing protocols, encouraging employees to work from home when possible, suspending non-essential work travel, frequently disinfecting our workspaces and providing appropriate personal protective equipment to employees who are physically present at our facilities. As COVID-19 conditions improved, we began implementing a phased reopening process (which we have since reversed in response to the identification of COVID-19 variants), encouraged our employees to receive COVID-19 vaccinations and COVID-19 booster shots as they become available. We will continue to implement appropriate safety measures until COVID-19 is contained. We may take further actions and adjust our reopening process as government authorities require or recommend or as we determine to be in the best interests of our employees, customers, partners and suppliers.

COVID-19 continues to be dynamic, and near-term challenges across the economy remain. The ongoing effects of COVID-19 remain difficult to predict due to numerous uncertainties, including the severity, duration and resurgence of the outbreak, new variants, the effectiveness of health and safety measures including vaccines, the pace and strength of the economic recovery, and supply chain pressures, among others. We will continue to actively monitor the effects of COVID-19 and will continue to take appropriate steps to mitigate the impacts to our employees and on our business results.

Critical Accounting Policies and Estimates

While our significant accounting policies are more fully described in the notes to our consolidated financial statements, we have identified the policies and estimates below as being critical to our business operations and the understanding of our results of operations. These policies require management’s most difficult, subjective or complex judgements, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. The impact of and any associated risks related to these policies on our business operations are discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” specifically in the “Results of Operations” section, where such policies affect our reported and expected financial results. Although we believe that our estimates, assumptions, and judgements are reasonable, they are based upon information presently available. Actual results may differ significantly from these estimates under different assumptions, judgments, or conditions.

Revenue recognition

We generate 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 Accounting Standards Codification No. (“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. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer (“transaction price”). To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the expected value method or the most likely amount method, depending on the facts and circumstances relative to the contract. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in paragraph 606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of December 31, 2021.

Contracts with customers may contain multiple performance obligations. For such arrangements, the transaction price is allocated to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The Company recognizes product revenue under the terms of each customer agreement upon transfer of control to the customer, which occurs at a point in time.

Allowance for credit losses

We evaluate our global accounts receivable through a continuous process of assessing our portfolio on an individual customer and overall basis. This process consists of a thorough review of historical collection experience, current aging status of the customer accounts, financial condition of our customers, and whether the receivables involve retainages. We also consider the economic environment of our customers, both from a marketplace and geographic perspective, in evaluating the need for an allowance. Based on our review of these factors, we establish or adjust allowances for specific customers. Credit losses can vary substantially over time and the process involves judgment and estimation that require a number of assumptions about matters that are uncertain. Accordingly, our results of operations can be affected by adjustments to the allowance due to actual write-offs that differ from estimated amounts. See Note 7, “Credit Losses,” to our consolidated financial statements included in this report for more information.

Inventories

We value inventory at cost or, if lower, net realizable value, using the first-in, first-out method. We review our inventory at least quarterly and record a provision for excess and obsolete inventory based on our estimates of expected sales volume, production capacity and expiration dates of raw materials, work-in-process and finished products. We write down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value, and inventory in excess of expected requirements to cost of product revenue. Manufacturing of bioprocessing finished goods is done to order and tested for quality specifications prior to shipment.

A change in the estimated timing or amount of demand for our products could result in additional provisions for excess inventory quantities on hand. Any significant unanticipated changes in demand or unexpected quality failures could have a significant impact on

the value of inventory and reported operating results. During all periods presented in the accompanying consolidated financial statements, there have been no material adjustments related to a revised estimate of inventory valuations.

Business combinations

Total consideration transferred for acquisitions is allocated to the tangible and intangible assets acquired and liabilities assumed, if any, based on their fair values at the dates of acquisition. This purchase price allocation process requires management to make significant estimates and assumptions with respect to intangible assets and deferred revenue obligations. The fair value of identifiable intangible assets is based on detailed valuations that use information and assumptions determined by management. Any excess of purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as any contingent consideration, where applicable, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we 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. The Company estimates the fair value of the contingent consideration earnouts using the Monte Carlo Simulation and updates the fair value of the contingent consideration at each reporting period based on the estimated probability of achieving the earnout targets and applying a discount rate that captures the risk associated with the expected contingent payments. To the extent that our estimates change in the future regarding the likelihood of achieving these targets, we may need to record material adjustments to our accrued contingent consideration. Such changes in the fair value of contingent consideration are recorded as contingent consideration expense in our consolidated statements of comprehensive income. For the year ended December 31, 2021, we recorded $5.9 million of contingent consideration expense related to the change in estimated contingent consideration obligations from the acquisition of Avitide, Inc. ("Avitide") in September 2021.

We use the income approach to determine the fair value of certain identifiable intangible assets including customer relationships and developed technology. This approach determines fair value by estimating after-tax cash flows attributable to these assets over their respective useful lives and then discounting these after-tax cash flows back to a present value. We base our assumptions on estimates of future cash flows, expected growth rates, expected trends in technology, etc. We base the discount rates used to arrive at a present value as of the date of acquisition on the time value of money and certain industry-specific risk factors. We believe the estimated purchased customer relationships, developed technologies, trademark/tradename, patents, non-competition agreements and in-process research and development amounts so determined represent the fair value at the date of acquisition and do not exceed the amount a third-party would pay for the assets.

Intangible assets and goodwill

Intangible assets

Intangible assets with a definite life are amortized over their useful lives using the straight-line method and the amortization expense is recorded within cost of product revenue, research and development and selling, general and administrative expense in the consolidated statements of comprehensive income. Intangible assets and their related useful lives are reviewed at least annually to determine if any adverse conditions exist, that would indicate the carrying value of these assets may not be recoverable. More frequent impairment assessments are conducted if certain conditions exist, including a change in the competitive landscape, any internal decisions to pursue new or different technology strategies, a loss of a significant customer, or a significant change in the marketplace, including changes in the prices paid for the Company’s products or changes in the size of the market for the Company’s products. If impairment indicators are present, the Company determines whether the underlying intangible asset is recoverable through estimated future undiscounted cash flows. If the asset is not found to be recoverable, it is written down to the estimated fair value of the asset based on the sum of the future discounted cash flows expected to result from the use and disposition 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 definite-lived intangible assets are recoverable at December 31, 2021.

Indefinite-lived intangible assets are tested for impairment at least annually. There has been no impairment of our intangible assets for the periods presented.

Goodwill

We test goodwill for impairment on an annual basis and between annual tests if events and circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying value. Events that would indicate impairment and trigger an interim impairment assessment include, but are not limited to, current economic and market conditions, including a decline in market capitalization, a significant adverse change in legal factors, business climate or operational performance of the business, and an adverse action or assessment by a regulator. Goodwill is tested for impairment as of December 31st of each year, or more frequently as warranted by events or changes in circumstances mentioned above. Accounting guidance also permits an optional qualitative assessment for goodwill to determine whether it is more likely than not that the carrying value of a reporting unit exceeds its fair value. If, after this qualitative assessment, we determine that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then no further quantitative testing would be necessary. A quantitative assessment is performed if the qualitative assessment results in a more likely than not determination or if a qualitative assessment is not performed. The quantitative assessment considers whether the carrying amount of a reporting unit exceeds its fair value, in which case an impairment charge is recorded to the extent the reporting unit’s carrying value exceeds its fair value.

The Company operates as one reporting unit. The fair value of the reporting unit is determined using both an income approach and market approach. Our income approach model used for our reporting unit valuation is consistent with that used for our December 31, 2019 goodwill impairment valuation noted above, except that cash flows from the entire business enterprise were used for the reporting unit valuation. Our market approach model estimated the fair value of the reporting unit based on market prices paid in actual precedent transactions of similar businesses and market multiples of guideline public companies. As a result of our 2020 quantitative assessment, we concluded that goodwill was not impaired as of December 31, 2020. During the qualitative assessment of the Company’s one reporting unit during the 2021 goodwill impairment testing, it was determined that it was not more likely than not that its fair value was less than its carrying amount. As such, a quantitative impairment assessment was not required as of December 31, 2021. If an event occurs or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying value, the Company will evaluate its goodwill for impairment between annual tests.

Accrued liabilities

We estimate accrued liabilities by identifying services performed on our behalf, estimating the level of service performed and determining the associated cost incurred for such service as of each balance sheet date. For example, we would accrue for professional and consulting fees incurred with law firms, audit and accounting service providers and other third-party consultants. These expenses are determined by either requesting those service providers to estimate unbilled services at each reporting date for services incurred or tracking costs incurred by service providers under fixed fee arrangements.

We have processes in place to estimate the appropriate amounts to record for accrued liabilities, which principally involve the applicable personnel reviewing the services provided. In the event that we do not identify certain costs that have begun to be incurred or we under or over-estimate the level of services performed or the costs of such services, the reported expenses for that period may be too low or too high. The date on which certain services commence, the level of services performed on or before a given date, and the cost of such services often require the exercise of judgment. We make these judgments based upon the facts and circumstances known at the date of the financial statements.

A change in the estimated cost or volume of services provided could result in additional accrued liabilities. Any significant unanticipated changes in such estimates could have a significant impact on our accrued liabilities and reported operating results. There have been no material adjustments to our accrued liabilities in any of the periods presented in the accompanying consolidated financial statements.

Debt accounting

Our short-term debt balance is related to our 0.375% Convertible Senior Notes due 2024 (the “2019 Notes”), which were issued in July 2019, and are carried at their principal amount less unamortized debt discount. We account for our convertible notes as separate liability and equity components. We estimate the carrying amount of the liability component by estimating the fair value of a similar liability that does not have an associated conversion feature. The Company allocates transaction costs related to the issuance of convertible notes to the liability and equity components using the same proportions as the initial carrying value of the convertible notes. The carrying value of the equity component is calculated by deducting the carrying value of the liability component from the

principal amount of the convertible notes as a whole. The difference represents a debt discount that is amortized to interest expense in our consolidated statement of comprehensive income over the term of the convertible notes using the effective interest rate method. We assess the equity classification of the cash conversion feature quarterly. We allocated transaction costs related to the issuance of the 2019 Notes to the liability and equity components using the same proportions as the initial carrying value of the 2019 Notes. In 2022, the Company will adopt Accounting Standards Update No. ("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)." This standard eliminates the liability and equity separation model for convertible instruments with a cash conversion feature. As a result, after adoption, the Company will no longer separately present in equity an embedded conversion feature for the 2019 Notes. Additionally, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the 2019 Notes. The Company is currently evaluating the impact of the adoption of ASU 2020-06 on the Company's consolidated financial statements.

Stock-based compensation

We use the Black-Scholes option pricing model to calculate the fair value of stock option awards on the grant date. The expected term of options granted represents the period of time for which the options are expected to be outstanding and is derived from our historical stock option exercise experience and option expiration data. For purposes of estimating the expected term, we have aggregated all individual option awards into one group, as we do not expect substantial differences in exercise behavior among our employees. The expected volatility is a measure of the amount by which our stock price is expected to fluctuate during the expected term of options granted. We determined the expected volatility based upon the historical volatility of our common stock over a period commensurate with the option’s expected term. The risk-free interest rate is the implied yield available on U.S. Treasury zero-coupon issues with a remaining term equal to the option’s expected term on the grant date. We have never declared or paid any cash dividends on any of our capital stock and do not expect to do so in the foreseeable future. Accordingly, we use an expected dividend yield of zero to calculate the grant-date fair value of a stock option.

The fair value for stock units, which include restricted stock units and performance stock units, is calculated using the closing price of the Company’s common stock on the date of grant. We recognize compensation expense on awards that vest based on service conditions on a straight-line basis over the requisite service period based upon the number of options that are ultimately expected to vest, and accordingly, such compensation expense has been adjusted by an amount of estimated forfeitures. We recognize compensation expense on awards that vest based on performance conditions following our assessment of the probability that the performance condition will be achieved over the service period. Forfeitures represent only the unvested portion of a surrendered option. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Based on an analysis of historical data, we have calculated an 8% annual forfeiture rate for non-executive level employees, a 3% annual forfeiture rate for executive level employees, and a 0% forfeiture rate for non-employee members of the Board of Directors, which we believe are reasonable assumptions to estimate forfeitures. However, the estimation of forfeitures requires significant judgment and, to the extent actual results or updated estimates differ from our current estimates, a cumulative adjustment to stock-based compensation expense will be recorded in the period estimates are revised.

For the years ended December 31, 2021, 2020 and 2019, we recorded stock-based compensation expense of $27.5 million, $17.0 million and $12.8 million, respectively, for share-based awards granted under all of the Company’s stock plans.

As of December 31, 2021, there was $59.2 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 3.16 years. We expect 1,953,733 unvested options and stock units to vest over the next five years.

Income taxes

Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided, if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. We account for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. We evaluate our tax position on a quarterly basis. We also accrue for potential interest and penalties related to unrecognized tax benefits in income tax expense.

In addition, we are subject to the continual examination of our income tax returns by the U.S. Internal Revenue Service (“IRS”) and other domestic and foreign tax authorities. We expect future examinations to focus on our intercompany transfer pricing practices as well as other matters. We regularly assess the likelihood of outcomes resulting from these examinations to determine the adequacy of our provision for income taxes and have reserved for potential adjustments that may result from such examinations. We believe such estimates to be reasonable; however, the final determination of any of these examinations could significantly impact the amounts provided for income taxes in our consolidated financial statements.

Recent accounting standards update

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 revenues for years ended December 31, 2021, 2020 and 2019 were comprised of the following:

(Amounts in thousands, except for percentage data)

Revenue:

Product revenues

Since 2016, we have been increasingly focused on selling our products directly to customers in the pharmaceutical industry and to our contract manufacturers. These direct sales have increased to 83.1% of our total product revenue during 2021 from 78.0% of our total product revenue in 2020. We expect that direct sales will continue to account for an increasing percentage of our product revenues, as the largest customer of our protein 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.

Product revenues were comprised of the following:

For the Years Ended December 31,

(Amounts in thousands)

(1)

2021 revenue for filtration products includes revenue related to Polymem from July 1, 2021 as well as BioFlex Solutions LLC ("BioFlex") and Newton T&M Corp ("NTM") from December 16, 2021 through December 31, 2021. 2021 revenue for proteins products includes revenue related to Avitide from September 20, 2021 through December 31, 2021.

(2)

2020 revenue for filtration products includes revenue related to Engineered Molding Technology LLC ("EMT") from July 13, 2020, Non-Metallic Solutions, Inc. ("NMS") from October 20, 2020 and ARTeSYN from December 3, 2020 through December 31, 2020.

(3)

2019 revenue includes process analytics revenue related to C Technologies from June 1, 2019 through December 31, 2019.

(4)

Revised 2020 and 2019 revenue in the table above reflects a shift in product revenue from chromatography products to proteins products of approximately $3 million and $4 million, respectively. These changes are consistent with the current year presentation of product revenue.

Revenue from our filtration products includes the sale of our XCell ATF® systems and consumables, KrosFlo® filtration products, SIUS® filtration products, the fluid management products offered by BioFlex, which we acquired on December 16, 2021, the hollow fiber ("HF") membrane technology offered by Polymem, which we acquired on July 1, 2021, the silicone-molded products offered by EMT, which we acquired on July 13, 2020 and the products offered by NMS and ARTeSYN, which were both acquired during the fourth quarter of 2020. Revenue from our chromatography products includes the sale of our OPUS chromatography columns, chromatography resins and ELISA test kits as well as sales of products offered by Avitide, which we acquired on September 20, 2021. 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.

For 2021, product revenue increased by $304.2 million, or 83.1%, as compared to 2020 with exceptional robust demand for our filtration, chromatography, process analytics and proteins products. The increase is due to the continued adoption of our products by key bioprocessing customers across all our key product lines. Beginning in the second quarter of 2020, we experienced an increase in overall sales as a result of accelerated demand across all our franchises due to the critical needs of customers working on COVID-19 vaccines and therapeutics. In addition, during 2021 we saw an increase in demand for C&GT and monoclonal antibody manufacturing. Revenue for 2021 also increased due to revenue from Polymem, Avitide, BioFlex and NTM, which we acquired during the second half of 2021. During 2021, we also include twelve months of revenue from our acquisitions executed in the second half of 2020, EMT, NMS and ARTeSYN, for which there was only a partial year of revenue commencing from the respective acquisition dates in 2020, through December 31, 2020.

Sales of our bioprocessing products are impacted by the timing of orders, development efforts at our customers or end-users and regulatory approvals for biologics that incorporate our products, which may result in significant quarterly fluctuations. Such quarterly fluctuations are expected, but they may not be predictive of future revenue or otherwise indicate a trend.

For 2020, product revenue increased by $96.0 million, or 35.6%, as compared to 2019. The increase was due to the continued adoption of our products by key bioprocessing customers across all our key product lines mentioned above. 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, C&GT and COVID-19 customers working on vaccines and therapeutics. In 2020, we also had good performance from our acquisitions executed in 2019 and 2020. C Technologies revenue increased by $16.9 million in 2020, compared to 2019, as 2020

represented twelve months of ownership of C Technologies, which was acquired in May 2019, compared to only seven months of ownership in 2019. Finally, as a result of our acquisitions of EMT, NMS and ARTeSYN in the second half of 2020, revenue from our filtration products included $6.2 million of additional revenue.

Royalty revenues

Royalty revenues in 2021 and 2020 relate to royalties received from a third-party systems manufacturer associated with our OPUS chromatography columns. Royalty revenues are variable and are dependent on sales generated by our partner.

Costs and operating expenses

Total costs and operating expenses for the years ended December 31, 2021, 2020 and 2019 were comprised of the following:

(Amounts in thousands, except for percentage data)

Contingent consideration expense 5,865 — — 5,865 100.0 % — N/A

Cost of product revenue

Cost of product revenue increased $122.6 million, or 78.3%, in 2021, as compared to 2020, due primarily to the increase in product revenue and costs associated with higher product volume. In addition, to support our rapid growth and increased demand for our products, we continue to invest in our manufacturing infrastructure through increased manufacturing headcount and increased occupancy costs. There was an approximately 84% increase in manufacturing headcount from December 31, 2020 to December 31, 2021, which resulted in higher employee-related costs. Our depreciation expense increased as manufacturing equipment was placed in service during 2021. The impact on cost of product revenue from our three acquisitions in 2021 was $7.4 million, which has also contributed to the increase in cost of product revenue as there were no comparable costs for these acquisitions in 2020.

Gross margin was 58.3% in 2021, as compared to 57.2% in 2020. The gross margin in 2021 included $2.1 million of amortization of inventory step-up associated with the Polymem Acquisition and ARTeSYN Acquisition and 2020 included $0.7 million of amortization of inventory step-up associated with the ARTeSYN Acquisition and the acquisition of EMT. Excluding the step-up amortization, gross margin for 2021 and 2020 was 58.7% and 57.4%, respectively. The increase in gross margin, excluding the inventory step-up amortization, in 2021, as compared to 2020, was due primarily to the increase in revenue mentioned above, and favorable product mix, partially offset by an increase in employee costs related to an increase in manufacturing headcount subsequent to December 31, 2020, an increase in occupancy costs due to added capacity in 2021 and an increase in depreciation expense mentioned above. Gross margins may fluctuate in future quarters based on expected production volume and product mix.

For 2020, cost of product revenue increased $37.5 million, or 31.5%, as compared to 2019, due primarily to the increase in product revenue and costs associated with higher product volume. An increase in manufacturing headcount resulted in higher employee-related costs in 2020, compared to 2019. Additional facility costs, including personal protection equipment purchased for essential manufacturing personnel on site to protect against COVID-19, were also incurred during 2020 for which there were no comparable amounts in 2019.

Gross margin was 57.2% in 2020, compared to 55.9% in 2019. The gross margin in 2020 included $0.7 million of amortization of inventory step-up associated with the EMT and ARTeSYN Acquisitions and the gross margin for 2019 included $1.5 million of amortization of inventory step-up associated with the C Technologies Acquisition in May 2019. Excluding the step-up amortization, gross margins in 2020 and 2019 were 57.4% and 56.5%, respectively. The increase in gross margins, excluding the inventory step-up amortization, in 2020, as compared to 2019, was due primarily to the increase in revenue mentioned above, and favorable product mix, partially offset by an increase in manufacturing headcount subsequent to December 31, 2019.

Research and development expenses

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

R&D expenses increased $14.1 million, or 69.8%, during 2021, as compared to 2020. The increase was due to the addition of R&D expenses related to operations of Avitide, Polymem and ARTeSYN, from their respective acquisition dates to December 31, 2021, including a full year of costs related to ARTeSYN programs for which there were costs from one month in 2020. Additionally, R&D costs increased, due to a rise in R&D headcount and the ramp up of project spending for new product development during 2021.

R&D expenses increased $0.7 million, or 3.8% in 2020, as compared to 2019. The increase was primarily due to a $1.1 million increase in C Technologies R&D expenses. C Technologies was acquired on May 31, 2019. Therefore, only seven months of expenses were recognized in 2019, compared to a full 12 months in 2020. The increase was partially offset by a decrease in R&D spending on external projects, as certain R&D process development laboratories were not fully functional for most of 2020 due to COVID-19.

R&D expense also includes investments made to expand our proteins product offering through our development agreement with Navigo Proteins GmbH (“Navigo”). The Company invested $2.3 million in 2021, $0.9 million in 2020 and $1.0 million in 2019 in the form of milestone payments to Navigo.

We expect our R&D expenses in 2022 to modestly 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 2021, SG&A costs increased by $64.2 million, or 53.7%, as compared to 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 and increased occupancy costs as well as an increase in depreciation related to assets placed in service during the year, all to support expected future growth. Employee-related costs during 2021, as compared to the same periods in 2020, resulted from the increase in headcount period over period. These costs include stock-based compensation expense, which increased $9.1 million in 2021, as compared to 2020. In addition, SG&A costs increased in 2021, due to the addition of EMT, NMS and ARTeSYN in the second half of 2020 and the addition of Polymem, Avitide, BioFlex and NTM during the second half of 2021, for which there were no comparable costs in 2020.

For 2020, SG&A costs increased by $24.0 million, or 25.1%, as compared to 2019. The increase was 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 in 2020, as compared to 2019, resulting from an increase in headcount and higher share prices period over period. In addition, $4.2 million of the increase in SG&A costs for 2020 was related to the C Technologies operations, which was acquired in May 2019. C Technologies’ SG&A costs for 2020 include a full year of costs, compared to only seven months in 2019. With the acquisitions of EMT, NMS and ARTeSYN in 2020, an additional $2.2 million of SG&A costs were included in the consolidated results.

Contingent consideration expense

Contingent consideration expense represents the change in fair value of the contingent consideration obligation included in noncurrent contingent consideration on the consolidated balance sheet as of the end of each period. Re-measurement of the contingent consideration obligation is done each quarter and the carrying value of the obligation is adjusted to the current fair value through our consolidated statement of comprehensive income. We recorded an adjustment to the fair value of the contingent consideration obligation for the year ended December 31, 2021 of $5.9 million.

Other expenses, net

(Amounts in thousands, except for percentage data)

Investment income

Investment income includes income earned on invested cash balances. The decrease of $1.6 million in 2021, as compared to 2020, is attributable to a decrease in interest rates on our invested cash balances and to a decrease in our average 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.

The decrease of $3.6 million in 2020, as compared to 2019, was also attributable to a decrease in interest rates on our invested cash balances. Higher average invested cash balances during 2020, as compared to 2019 due to the completion of a public offering and the issuance of our 2019 Notes during the third quarter of 2019, partially offset the decrease in interest rates mentioned above.

Loss on conversion of debt

The loss on conversion of debt in 2021 is a result of the settlement of the conversion of $11,000 aggregate principal of our 2019 Notes. We had no loss on conversion of debt in 2020.

The $5.7 million loss on conversion of debt for the year ended December 31, 2019 resulted from the settlement of our outstanding 2.125% Convertible Senior Notes due 2021 (the “2016 Notes”) in the third quarter of 2019. The loss represents the difference between (i) the fair value of the liability component and (ii) the sum of the carrying value of the debt component and any unamortized debt issuance costs at the time of settlement.

Interest expense

Interest expense in 2021 and 2020 is primarily from our 2019 Notes. Interest expense, which includes the amortization of debt issuance costs and contractual coupon interest, increased $0.6 million in 2021, as compared to 2020. This is a result of the decrease in the balance of debt issuance costs that are being amortized. As these costs decrease, the carrying value of the debt increases and interest calculated based on the carrying value increases as well.

Interest expense in 2020 was primarily from our 2019 Notes. In 2019, interest expense was from a combination of our 2016 Notes, which were settled during the third quarter of 2019 and our 2019 Notes. Interest expense increased $2.8 million in 2020, as compared to 2019 based on the increase in debt issued from $115.0 million for the 2016 Notes to $287.5 million for the 2019 Notes.

The amortization of debt issuance costs on the 2019 Notes was $11.5 million and $11.0 million in 2021 and 2020, respectively. Amortization of debt issuance costs on the 2019 Notes was $4.7 million in 2019. The amortization of the debt issuance costs on the 2016 Notes was $2.8 million in 2019.

Contractual coupon interest incurred on the 2019 Notes in 2021 and 2020 was $1.1 million in each year. Interest calculated based on the carrying value related to the 2019 Notes for 2019 was $0.5 million. Contractual coupon interest incurred on the 2016 Notes was

$1.3 million in 2019. Since the 2016 Notes were settled during July 2019, interest no longer accrued on the 2016 Notes subsequent to their settlement.

Other expenses, net

The change in other expenses, net in 2021, as compared to 2020, is primarily attributable to realized foreign currency losses related to amounts due from non-Swedish krona-based customers and vendors.

The change in other expenses during 2020, as compared to 2019, was primarily attributable to realized foreign currency losses related to amounts due from non-Swedish krona-based customers and vendors. In addition, $0.5 million was included in other expenses in 2019, which represents a bridge loan commitment fee incurred as part of the C Technologies Acquisition.

Income tax provision (benefit)

Income tax provision (benefit) for the years ended December 31, 2021, 2020 and 2019 was as follows:

(Amounts in thousands, except for percentage data)

For 2021, we recorded an income tax provision of $25.3 million. The effective tax rate in 2021 was 16.4% 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. Our effective tax rate for 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.

In 2020, we recorded an income tax benefit of $0.7 million. Our effective tax rate in 2020 was (1.2%) and was based upon the estimated income for the year ending December 31, 2020 and the composition of income in different jurisdictions. Our effective tax rate in 2020 was lower than the U.S. statutory rate of 21% primarily due to windfall benefits on stock option exercises and the vesting of stock units.

For the year ended December 31, 2019, we recorded an income tax provision of approximately $4.7 million. Our effective tax rate was an income tax provision of 18.1% and was based upon the estimated taxable income for the year ending December 31, 2019 and the composition of the taxable income in different jurisdictions. Our effective tax rate was lower than the U.S. statutory rate of 21% due primarily to windfall benefits on stock option exercises and the vesting of restricted stock units and to deductions related to debt extinguishment.

Non-GAAP Financial Measures

We provide non-GAAP adjusted income from operations, non-GAAP adjusted net income and adjusted EBITDA as supplemental measures to GAAP measures regarding our operating performance. These financial measures exclude the impact of certain acquisition related items and, therefore, have not been calculated in accordance with GAAP. A detailed explanation and a reconciliation of each non-GAAP financial measures to its most comparable GAAP financial measures are described 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, inventory step-up charges, contingent consideration expense and intangible amortization booked through our consolidated statements of comprehensive income. The following is a reconciliation of income from operations in accordance with GAAP to non-GAAP adjusted income from operations for the years ended December 31, 2021 and 2020:

Liquidity and Capital Resources

We have financed our operations primarily through revenues derived from product sales, the issuance of the 2016 Notes in May 2016 and our 2019 Notes in July 2019 and the issuance of common stock in our December 2020, July 2019 and May 2019 public offerings. Our revenue for the foreseeable future will primarily be limited to our bioprocessing product revenue.

At December 31, 2021, we had cash and cash equivalents of $603.8 million compared to cash and cash equivalents of $717.3 million at December 31, 2020. There were no restrictions on cash as of December 31, 2021.

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 2021 we acquired three companies for an aggregate of $149.9 million in cash, net of cash acquired. In connection with the acquisitions, the Company has an obligation to pay up to $62.5 million (undiscounted) in contingent consideration earnout payments in cash over a three-year performance period beginning January 1, 2022 and ending December 31, 2024. See Note 2, “Fair Value Measurements,” and Note 4, “Acquisitions,” for additional information. In 2020, we acquired three companies for an aggregate of $175.0 million in cash, net of cash acquired. All obligations related to these acquisitions have been settled.

We acquired C Technologies on May 31, 2019 for $239.9 million in cash and shares of our common stock. The C Technologies Acquisition was funded through payment of approximately $195.0 million in cash and issuance of 779,221 unregistered shares of the Company’s common stock totaling $53.9 million.

On July 19, 2019, the Company completed a public offering in which 1,587,000 shares of its common stock, including the underwriters’ full exercise of an option to purchase an additional 207,000 shares, were sold to the public at a price of $87.00 per share for $131.1 million in net proceeds to the Company, after deducting underwriting discounts and commissions and other estimated offering expenses payable by the Company (the “July Stock Offering”).

On July 19, 2019, the Company issued $287.5 million aggregate principal amount of 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” and, together with the July Stock Offering, the “Offerings”). The net proceeds of the Notes Offering, after deducting underwriting discounts and commissions and other offering expenses payable by the Company, were $278.5 million. See Note 13, “Convertible Senior Notes,” included in this reportfor more information on this transaction.

On May 3, 2019, the Company completed a public offering in which 3,144,531 shares of its common stock, including the underwriters’ full exercise of an option to purchase up to an additional 410,156 shares, were sold to the public at a price of $64.00 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, totaled approximately $189.6 million. Proceeds from this public offering were partially used to fund the C Technologies Acquisition on May 31, 2019.

During the fourth 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 first quarter of 2022 per the First Supplemental Indenture underlying the 2019 Notes. The 2019 Notes have a face value of $287.5 million and a carrying value of $255.3 million. The Company expects to continue meeting these terms and has again classified the carrying value of the 2019 Notes as current liabilities on the Company’s balance sheet as of December 31, 2021 and 2020. As of the date of this filing, the Company has received requests to convert $13,000 aggregate principal amount of 2019 Notes of which $11,000 have been settled and $2,000 still remain in the Observation Period (as defined by the First Supplemental Indenture dated as of December 31, 2021), which the Company will settle during the first quarter of 2022. We intend to pay or deliver, as the case may be, the settlement amount to be determined – paying the amount in excess of the aggregate principal portion of the converted notes in shares of our common stock.

In 2021, we had lease arrangements for certain equipment and facilities including corporate and manufacturing sites. As of December 31, 2021, the Company had fixed lease payment obligations of $110.8 million, with $8.3 million payable within 12 months. See Note 5, “Leases”, for additional information.

In 2021, we had other purchase obligations primarily consisting of purchase commitments with certain vendors and open purchase orders for the procurement of raw materials for manufacturing. As of December 31, 2021, the Company had other purchase obligations of $148.7 million, payable within 12 months.

Cash flows

For the Years Ended December 31, FY21 vs FY20 FY20 vs FY19

(Amounts in thousands)

Cash provided by (used in):

Operating activities

For 2021, our operating activities provided cash of $119.0 million reflecting net income of $128.3 million and non-cash charges totaling $92.9 million primarily related to depreciation, amortization, inventory step-up amortization, contingent consideration expense, deferred income taxes, amortization of debt discount and issuance costs and stock-based compensation charges. An increase in accounts receivable consumed $46.5 million of cash and was primarily driven by the 83.1% year-to-date increase in total revenues. An increase in inventory manufactured of $89.8 million supports expected increases in future revenue and an increase in prepaid expenses, specifically insurance and taxes of $10.2 million. The increases in accounts receivable, prepaid expenses and inventory

manufactured are offset by an increase in accounts payable of $19.5 million, which is primarily due to increased inventory purchases to support customer orders, an increase in accrued liabilities of $23.2 million, which was due to an increase in the accrual for expected costs, taxes payable, and to a decrease in deferred revenue related to products shipped during the first half of 2021. The remaining net cash used in operating activities resulted from unfavorable changes in various other working capital accounts.

For 2020, our operating activities provided cash of $62.6 million reflecting net income of $59.9 million and non-cash charges totaling $51.3 million primarily related to depreciation, amortization, non-cash interest expense, deferred taxes and stock-based compensation charges. An increase in accounts receivable consumed $21.0 million of cash and was primarily driven by the 35.5% year-to-date increase in total revenues and an increase in inventory manufactured of $29.3 million to support expected continued growth in future revenues. In addition, $4.9 million was consumed for increases in prepaid expenses for annual software and network contracts, as well as the renewal of the Company’s global insurance policies. These were offset by an increase in accounts payable and accrued liabilities of $3.5 million due primarily to increased inventory purchases to support customer orders and year-end tax adjustments, offset by payment of acquisition-related bonuses for C Technologies during the second quarter of 2020. The remaining cash source of operating activities resulted from favorable changes in various other working capital accounts.

For 2019, our operating activities provided cash of $67.2 million reflecting net income of $21.4 million and non-cash charges totaling $46.9 million primarily related to depreciation, amortization, non-cash interest expense, deferred taxes, loss on conversion of debt and stock-based compensation charges. An increase in accounts receivable consumed $7.7 million of cash and was primarily driven by the 39% year-to-date increase in revenues and an increase in inventory consumed $9.3 million to support future revenue, due to the addition of C Technologies on May 31, 2019. These were offset by an increase in accounts payable and accrued liabilities of $13.8 million due to the addition of C Technologies and a decrease in unbilled receivables of $2.1 million. The remaining cash used in operating activities resulted from unfavorable changes in various other working capital accounts.

Investing activities

Our investing activities consumed $221.2 million of cash during 2021. We used $149.9 million in cash (net of cash received) for the acquisitions of Polymem, Avitide, BioFlex and NTM, in the aggregate. Capital expenditures consumed $71.3 million as we continue to increase our manufacturing capacity worldwide. Of these expenditures, $4.2 million represented capitalized costs related to our internal-use software.

Our investing activities consumed $201.4 million of cash during 2020. We used $175.0 million in cash (net of cash received) for the EMT, NMS and ARTeSYN Acquisitions. Capital expenditures consumed $26.3 million as we continue to increase our manufacturing capacity worldwide. Of these expenditures, $3.9 million represented capitalized costs related to our internal-use software.

Our investing activities consumed $205.3 million of cash during 2019. We used $182.2 million in cash (net of cash received) for the C Technologies Acquisition on May 31, 2019. Capital expenditures consumed $23.2 million as we continue to increase our manufacturing capacity worldwide. Of these expenditures, $4.7 million represented capitalized costs related to our internal-use software.

Financing activities

In 2021, cash provided by financing activities of $1.0 million included proceeds from stock option exercises, offset by cash disbursed in relation to shares withheld to cover employee income taxes due upon the vesting and release of restricted stock units. Proceeds from stock option exercises during 2021 were $3.9 million offset by $2.9 million of cash disbursed to pay tax obligation on the vesting of restricted stock units.

In 2020, cash provided by financing activities of $305.9 million included $297.8 million from the issuance of our common stock resulting from our public offerings completed in December 2020. Proceeds from stock option exercises during 2020 were $8.2 million.

In 2019, cash provided by financing activities of $484.9 million included $320.7 million from the issuance of our common stock resulting from our public offerings completed in May and July 2019. In addition, in July 2019 the Company issued $287.5 million aggregate principal amount of the 2019 Notes for net proceeds of $278.5 million. Proceeds from stock option exercises during 2019

were $1.2 million. Offsetting these activities was $115.0 million of cash utilized by the Company in July 2019 to settle the 2016 Notes.

Effect of exchange rate changes on cash, cash equivalents and restricted cash

The effect of exchange rate changes on cash during 2021 is a result of the weakening of the Swedish krona against the U.S. Dollar by 10% and the weakening of the Euro against the U.S. Dollar by 8%.

Off-Balance Sheet Arrangements

We do not have any special purpose entities or off-balance sheet financing arrangements.

Capital Requirements

Our future capital requirements will depend on many factors, including the following:

•

the expansion of our bioprocessing business;

•

the ability to sustain sales and profits of our bioprocessing products;

•

our ability to acquire additional bioprocessing products;

•

the scope of and progress made in our research and development 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. We expect operating expenses in 2022 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, for example, due to acquisition-related financing needs or lower demand for our products, among potential other events, we may seek to sell common or preferred equity or convertible debt securities, enter into a credit facility or another form of third-party funding, or seek other debt funding. The sale of equity and convertible debt securities may result in dilution to our stockholders, and those securities may have rights senior to those of our common shares. If we raise additional funds through the issuance of preferred stock, convertible debt securities or other debt financing, these securities or other debt could contain covenants that would restrict our operations. Any other third-party funding arrangement could require us to relinquish valuable rights. We may require additional capital beyond our currently anticipated amounts. Additional capital may not be available on reasonable terms, if at all.

Net Operating Loss Carryforwards

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

December 2041. Net operating loss carryforwards and available tax credits are subject to review and possible adjustment by the Internal Revenue Service, state and foreign jurisdictions and may be limited in the event of certain changes in the ownership interest of significant stockholders.

Foreign Earnings

As of December 31, 2021, the Company has accumulated undistributed earnings generated by our foreign subsidiaries of approximately $93.3 million. Because $5.7 million of such earnings have previously been subject to the one-time transition tax on foreign earnings required by the 2017 Tax Cuts and Jobs Act enacted in December 2017, any additional taxes due with respect to such earnings or the excess of the amount for financial reporting over the tax basis of our foreign investments would generally be limited to foreign and state taxes. At December 31, 2021, we have not provided for taxes on outside basis differences of our foreign subsidiaries, as we have the ability and intent to indefinitely reinvest the undistributed earnings of our foreign subsidiaries, and there are no needs for such earnings in the United States that would contradict our plan to indefinitely reinvest.

Effects of Inflation

Our assets are primarily monetary, consisting of cash and cash equivalents. Because of their liquidity, these assets are not directly affected by inflation. Since we intend to retain and continue to use our equipment, furniture, fixtures and office equipment, computer hardware and software and leasehold improvements, we believe that the incremental inflation related to replacement costs of such items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase our level of expenses and the rate at which we use our resources.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in interest rates and foreign currency exchange rates.

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

Although a majority of our contracts are denominated in U.S. Dollars, 37.5% and 29.8% of total revenues during 2021 and 2020, respectively, were denominated in foreign currencies while 27.1% and 6.8% of our costs and expenses during 2021 and 2020, respectively, were denominated in foreign currencies, primarily operating expenses associated with cost of revenue, sales and marketing and general and administrative. In addition, 17.7% and 21.8% of our consolidated tangible assets were subject to foreign

currency exchange fluctuations as of each of December 31, 2021 and 2020, respectively, while 9.6% and 5.7% of our consolidated liabilities were exposed to foreign currency exchange fluctuations as of each of December 31, 2021 and 2020, respectively.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Financial statements and supplementary data required by Item 8 are set forth at the pages indicated in Item 15(a) below and are incorporated herein by reference.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

None.

ITEM 9A. CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures.

The Company’s management, with the participation of our principal executive officer and 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 and as required by paragraph (b) of Rules 13a-15 or 15d-15 under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our 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.

(b) Report of Management on Internal Control Over Financial Reporting.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles and includes those policies and procedures that:

•

pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

•

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

•

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021. In making this assessment, management used the criteria established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO).

We acquired Polymem S.A. (“Polymem”) on July 1, 2021, Avitide Inc. (“Avitide”) on September 20, 2021 and BioFlex Solutions LLC (“BioFlex”) and Newton T&M Corp. (“NTM”) on December 16, 2021. The financial results of each of these acquisitions are included in our audited consolidated financial statements as of December 31, 2021. The Company's consolidated total assets as of December 31, 2021 includes $52.4 million, $253.3 million and $33.4 million from the Polymem, Avitide, and NTM and BioFlex businesses, respectively. The Company's consolidated revenue for the year ended December 31, 2021 includes $2.3 million, $1.3 million and $0.1 million, from Polymem, Avitide, NTM and Bioflex businesses, respectively. As these acquisitions occurred in the third or fourth quarter of 2021, the scope of our assessment of our internal control over financial reporting does not include these acquisitions. These exclusions are in accordance with the SEC’s general guidance that an assessment of a recently acquired business may be omitted from our scope in the year of such acquisition.

In connection with our initiative to integrate and enhance our global information technology systems and business processes, we continued the phased implementation of a new enterprise resource planning (“ERP”) system. The implementation of the ERP system is done in phases and will continue until all current and future subsidiaries are using it. The third phase of this project was completed during the second quarter of 2021. As a result of this implementation, we modified certain existing internal controls over financial reporting as of December 31, 2021.

Other than the foregoing, 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 December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Subject to the foregoing, based on this assessment, our management concluded that, as of December 31, 2021, our internal control over financial reporting is effective based on those criteria. Ernst & Young LLP, the independent registered public accounting firm that audited our financial statements included in this Form 10-K, has issued an attestation report on our internal control over financial reporting as of December 31, 2021.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Repligen Corporation:

Opinion on Internal Control over Financial Reporting

We have audited Repligen Corporation’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Repligen Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.

As indicated in the accompanying Report of Management on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Polymem S.A. ("Polymem"), Avitide, Inc. ("Avitide"), Newton T&M Corp ("NTM") and Bio-Flex Solutions, LLC ("Bioflex"), which are included in the 2021 consolidated financial statements of the Company and constituted $52.4 million, $253.3 million and $33.4 million of total assets, respectively, as of December 31, 2021, and $2.3 million, $1.3 million and $0.1 million of revenues, respectively, for the year to date 2021. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Polymem, Avitide, NTM and Bioflex.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes and our report dated February 17, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Report of Management on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Repligen Corporation:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Repligen Corporation (the Company) as of December 31, 2021 and 2020, the related consolidated statements of comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 17, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the US federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not,

by communicating the critical audit matters below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Organization and Nature of Business

Repligen Corporation (NASDAQ:RGEN) is a global life sciences company that develops and commercializes highly innovative bioprocessing technologies and systems that increase efficiencies and flexibility in the process of manufacturing biological drugs. The Company’s franchises include filtration (XCell ATF® systems, TangenXTM SIUS® flat sheet cassettes, Spectrum® Hollow Fibers, KrosFlo® systems and ProConnex® single-use flow path assemblies), chromatography (OPUS® Columns, chromatography resins, ELISA kits), process analytics (SoloVPE®, FlowVPE® and Flow VPX®) and proteins (Protein A affinity ligands and cell culture growth factors). The Company’s bioprocessing products are sold to major life sciences companies, biopharmaceutical development companies and contract manufacturing organizations worldwide. The Company operates under one reportable segment. The Company’s chief operating decision maker (“CODM”) reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. See Note 2, “Summary of Significant Accounting Policies – Segment Reporting,” for more information on the Company’s segment.

A majority of our 16 key manufacturing sites are located in the United States (California, Massachusetts, New Jersey and New York). Outside the United States, we have manufacturing sites in Estonia, France, Germany, Ireland, the Netherlands and Sweden.

The Company is subject to a number of risks typically associated with companies in the biotechnology industry. These risks principally include the Company’s dependence on key customers, development by the Company or its competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with the FDA and other governmental regulations and approval requirements, as well as the ability to grow the Company’s business and obtain adequate funding to finance this growth.

Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods.

Significant estimates and assumptions by management affect the Company’s revenue recognition for multiple element arrangements, allowance for credit losses, the net realizable value of inventory, valuations and purchase price allocations related to business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets, contingent consideration, estimated fair values of intangible assets and goodwill, amortization methods and periods, warranty reserves, certain accrued expenses, stock-based compensation, tax reserves and recoverability of the Company’s net deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances.

Basis of Presentation

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”), ARTeSYN Biosolutions Holdings Ireland Limited and its subsidiaries (“ARTeSYN”), Polymem S.A. (“Polymem”), Avitide, Inc. (“Avitide”), Newton T&M Corp ("NTM"), Bio-Flex Solutions, LLC ("BioFlex") and Repligen Singapore Pte. Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain prior year balances have changed to reflect current year presentation.

Foreign Currency

The Company translates the assets and liabilities of its foreign subsidiary at rates in effect at the end of the reporting period. Revenues and expenses are translated at average rates in effect during the reporting period. Translation adjustments, including adjustments related to the Company’s various intercompany loans. Any intercompany loans with foreign subsidiaries are remeasured at each period end and included in accumulated other comprehensive loss on the consolidated balance sheets.

Revenue Recognition

We generate revenue from the sale of bioprocessing products, equipment devices, and related consumables used with these equipment devices to customers in the life sciences and biopharmaceutical industries. Under Accounting Standard Codification No. (“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. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer (“transaction price”). To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the expected value method or the most likely amount method, depending on the facts and circumstances relative to the contract. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

The Company recognizes product revenue under the terms of each customer agreement upon transfer of control to the customer, which occurs at a point in time.

Shipping and handling fees are recorded as a component of product revenue, with the associated costs recorded as a component of cost of product revenue.

Risks and Uncertainties

The Company evaluates its operations periodically to determine if any risks and uncertainties exist that could impact its operations in the near term. The Company does not believe that there are any significant risks that have not already been disclosed in the consolidated financial statements. A loss of certain suppliers could temporarily disrupt operations, although alternate sources of supply exist for these items. The Company has mitigated these risks by working closely with key suppliers, identifying alternate sources and developing contingency plans.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash on hand and on deposit. Highly liquid investments in money market mutual funds with an original maturity of three months or less are classified as cash equivalents. All cash equivalents are carried at cost, which approximates fair value. Restricted cash represents cash that is restricted as to withdrawal or usage. There was no restriction on

the Company’s cash balance as of December 31, 2021 and 2020. In connection with the Company’s acquisition of C Technologies on May 31, 2019, cash was held and due to employees based on their continued employment with the Company one year after the date of the close of the acquisition. As of December 31, 2019, $9.0 million, which represented this amount due to employees, was carried as restricted cash on the Company’s consolidated balance sheet. Subsequently, during the second quarter of 2020, this $9.0 million was paid to employees.

The following is a summary of the Company’s cash, cash equivalents, and restricted cash total as presented in the Company’s consolidated statements of cash flows for the years ended December 31, 2021, 2020 and 2019:

For the Years Ended December 31,

(Amounts in thousands)

Restricted cash — — 9,015

There were no realized gains or losses on investments for the years ended December 31, 2021, 2020 and 2019.

Fair Value Measurement

In determining the fair value of its assets and liabilities, the Company uses various valuation approaches. 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:

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.

Allowance for credit losses

We establish an allowance for credit losses through a review of several factors, including historical collection experience, current aging status of the customer accounts, and current financial condition of our customers. Losses are charged against the allowance when the customer accounts are determined to be uncollectible.

Inventories

Inventories relate to the Company’s bioprocessing business. The Company values inventory at cost or, if lower, net realizable value, using the first-in, first-out method. The Company reviews its inventories at least quarterly and records a provision for

excess and obsolete inventory based on its estimates of expected sales volume, production capacity and expiration dates of raw materials, work-in-process and finished products. The Company writes down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value, and inventory in excess of expected requirements to cost of product revenue. Manufacturing of bioprocessing finished goods is done to order and tested for quality specifications prior to shipment.

A change in the estimated timing or amount of demand for the Company’s products could result in additional provisions for excess inventory quantities on hand. Any significant unanticipated changes in demand or unexpected quality failures could have a significant impact on the value of inventory and reported operating results. During all periods presented in the accompanying consolidated financial statements, there have been no material adjustments related to a revised estimate of inventory valuations.

Work-in-process and finished products inventories consist of material, labor, outside processing costs and manufacturing overhead.

Lease Accounting

The Company adopted Accounting Standards Update No. ("ASU") 2016-02, “Leases (Topic 842)” (“ASC 842”) as of January 1, 2019. Under ASC 842, the Company determines whether the arrangement contains a lease at the inception of an arrangement. If a lease is identified in an arrangement, the Company recognizes a right-of-use asset and liability on its consolidated balance sheet and determines whether the lease should be classified as a finance or operating lease. The Company does not recognize assets or liabilities for leases with lease terms of less than 12 months.

A lease qualifies as a finance lease if any of the following criteria are met at the inception of the lease: (i) there is a transfer of ownership of the leased asset to the Company by the end of the lease term, (ii) the Company holds an option to purchase the leased asset that it is reasonably certain to exercise, (iii) the lease term is for a major part of the remaining economic life of the leased asset, (iv) the present value of the sum of lease payments equals or exceeds substantially all of the fair value of the leased asset, or (v) the nature of the leased asset is specialized to the point that it is expected to provide the lessor no alternative use at the end of the lease term. All other leases are recorded as operating leases.

Finance and operating lease assets and liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term using the discount rate implicit in the lease. If the rate implicit is not readily determinable, the Company utilizes its incremental borrowing rate at the lease commencement date. Operating lease assets are further adjusted for prepaid or accrued lease payments. Operating lease payments are expensed using the straight-line method as an operating expense over the lease term. Finance lease assets are amortized to depreciation expense using the straight-line method over the shorter of the useful life of the related asset or the lease term. Finance lease payments are bifurcated into (i) a portion that is recorded as imputed interest expense and (ii) a portion that reduces the finance liability associated with the lease.

The Company does not separate lease and non-lease components when determining which lease payments to include in the calculation of its lease assets and liabilities. Variable lease payments are expensed as incurred. If a lease includes an option to extend or terminate the lease, the Company reflects the option in the lease term if it is reasonably certain it will exercise the option.

Finance leases are recorded in property, plant and equipment, net, other current liabilities and long-term finance lease liabilities and operating leases are recorded in operating lease right of use assets, operating lease liability and operating lease liability, long-term on the Company’s consolidated balance sheet.

Certain of the Company’s operating leases where the Company is the lessee provide for minimum annual payments that increase over the life of the lease. Some of these leases include obligations to pay for other services, such as operations and maintenance. For leases of property, the Company accounts for these other services as a component of the lease. The aggregate minimum annual payments are expensed on the straight-line basis beginning when the Company takes possession of the property and extending over the term of the related lease, including renewal options when the exercise of the option is reasonably certain as an economic penalty may be incurred if the option is not exercised. The Company also accounts in its straight-line computation for the effect of any “rental holidays.”

Operating lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of the fixed lease payments, reduced by landlord incentives using a discount rate based on similarly secured borrowings available to the Company. Most of the leases do not provide implicit interest rates and therefore the Company determines the discount rate based on its incremental borrowing rate. The incremental borrowing rate for the Company’s leases is determined based on lease term and currency in which the lease payments are made.

Accrued Liabilities

The Company estimates accrued liabilities by identifying services performed on the Company’s behalf, estimating the level of service performed and determining the associated cost incurred for such service as of each balance sheet date. For example, the Company would accrue for professional and consulting fees incurred with law firms, audit and accounting service providers and other third-party consultants. These expenses are determined by either requesting those service providers to estimate unbilled services at each reporting date for services incurred or tracking costs incurred by service providers under fixed fee arrangements.

The Company has processes in place to estimate the appropriate amounts to record for accrued liabilities, which principally involve the applicable personnel reviewing the services provided. In the event that the Company does not identify certain costs that have begun to be incurred or the Company under or over-estimates the level of services performed or the costs of such services, the reported expenses for that period may be too low or too high. The date on which certain services commence, the level of services performed on or before a given date, and the cost of such services often require the exercise of judgment. The Company makes these judgments based upon the facts and circumstances known at the date of the financial statements.

Income Taxes

Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are provided, if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company accounts for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. The Company evaluates this tax position on a quarterly basis. The Company also accrues for potential interest and penalties related to unrecognized tax benefits in income tax expense.

Property, Plant & Equipment

Property, plant & equipment is recorded at cost less allowances for depreciation. Depreciation is calculated using the straight-line method over the estimated useful life of the asset as follows:

Classification Estimated Useful Life

Buildings Thirty years

Leasehold improvements Shorter of the term of the lease or estimated useful life

Equipment Three to twelve years

Furniture, fixtures and office equipment Three to eight years

Computer hardware and software Three to seven years or estimated useful life

Upon disposal of property, plant & equipment, the cost of the asset and the accumulated depreciation are removed from the accounts and the resulting gain or loss is reflected in our results of operations. Fully depreciated assets are not removed from the accounts until they are physically disposed of.

Certain systems development costs related to the purchase, development and installation of computer software developed or obtained for internal use are capitalized and depreciated over the estimated useful life of the related project. Costs incurred prior

to the development stage, as well as maintenance, training costs, and general and administrative expenses are expensed as incurred.

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 restricted stock awards and the incremental common shares issuable upon the exercise of stock options and warrants. Under the treasury stock method, unexercised “in-the-money” stock options 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 share amounts is as follows:

Earnings per share:

At December 31, 2021, there were outstanding options to purchase 625,107 shares of the Company’s common stock at a weighted average exercise price of $54.15 per share and 606,685 shares of common stock issuable upon the vesting of stock units which include restricted stock units and performance stock units. For the year ended December 31, 2021, 68,968 shares of the Company’s common stock were excluded from the calculation of diluted earnings per share because they would have had an anti-dilutive effect.

At December 31, 2020, there were outstanding options to purchase 696,711 shares of the Company’s common stock at a weighted average exercise price of $43.88 per share and 665,540 shares of common stock issuable upon the vesting of stock units. For the year ended December 31, 2020, 98,048 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 December 31, 2019, there were outstanding options to purchase 957,559 shares of the Company’s common stock at a weighted average exercise price of $30.81 per share and 734,984 shares of common stock issuable upon the vesting of stock units. For the year ended December 31, 2019, 104,316 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 December 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.

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 convertible 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 years ended December 31, 2021, 2020 and 2019, the dilutive effect of the conversion premium included in the calculation of diluted earnings was 1,253,168 shares, 366,534 shares and 1,123,139 shares, respectively. In 2022, the Company will adopt Accounting Standards Update No. ("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)." Once adopted, the 2019 Notes will be subject to the "if-converted" method for calculating diluted earnings per share. Under the "if-converted" method, diluted earnings per share will be calculated assuming that all of the convertible notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be anti-dilutive. The Company is currently evaluating the impact of the adoption of ASU 2020-06 on the Company's consolidated financial statements.

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 December 31, 2021, the Company had no investments associated with foreign exchange contracts, options contracts or other foreign hedging arrangements.

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

Revenue from significant customers that represent 10% or more of the Company’s total revenue is as follows:

Business Combinations, Goodwill and Intangible Assets

Business Combinations

Total consideration transferred for acquisitions is allocated to the tangible and intangible assets acquired and liabilities assumed, if any, based on their fair values at the dates of acquisition. This purchase price allocation process requires management to make significant estimates and assumptions with respect to intangible assets and deferred revenue. The fair value of identifiable intangible assets is based on detailed valuations that use information and assumptions determined by management. Any excess of purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as any contingent consideration, where applicable, the Company’s estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records 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 the Company’s consolidated statements of comprehensive income. Any excess of the fair value of the net tangible and intangible assets acquired over the purchase price is recognized in the consolidated statements of comprehensive income. The fair value of contingent consideration includes estimates and judgments made by management regarding the probability that future contingent payments will be made and the extent of royalties to be earned in excess of the defined minimum royalties. Management updates these estimates and the related fair value of contingent consideration at each reporting period. These changes in the fair value of contingent consideration are recorded to contingent consideration expense in our consolidated statements of comprehensive income. For the year ended December 31, 2021, we recorded $5.9 million of contingent consideration expense related to the change in estimated contingent consideration obligation related to the Avitide Acquisition.

The Company uses the income approach to determine the fair value of certain identifiable intangible assets including customer relationships and developed technology. This approach determines fair value by estimating after-tax cash flows attributable to these assets over their respective useful lives and then discounting these after-tax cash flows back to a present value. The Company bases its assumptions on estimates of future cash flows, expected growth rates, expected trends in technology, etc. Discount rates used to arrive at a present value as of the date of acquisition are based on the time value of money and certain industry-specific risk factors. The Company believes the estimated purchased customer relationships, developed technologies, trademark/tradename, patents, non-compete agreements and in-process R&D amounts so determined represent the fair value at the date of acquisition, and do not exceed the amount a third-party would pay for such assets.

Goodwill

Goodwill is not amortized and is tested for impairment at least annually at the reporting unit level. In 2019, the Company reorganized its reporting structure and changed the way the CODM views the Company’s operations and allocates its resources. Accordingly, the Company operates as one reporting unit as of the goodwill impairment measurement date of December 31, 2021. During the qualitative assessment of the Company’s one reporting unit during the 2021 goodwill impairment testing, it was determined that it was not more likely than not that its fair value was less than its carrying amount. As such, a quantitative impairment assessment was not required as of December 31, 2021. If an event occurs or circumstances change that would more likely than not reduce the fair value of its reporting unit below its carrying value, the Company will evaluate its goodwill for impairment between annual tests. There was no impairment to goodwill and therefore no impairment charge recorded for the years ended December 31, 2021, 2020 and 2019.

Intangible Assets

Intangible assets with a definite life are amortized over their useful lives using the straight-line method and the amortization expense is recorded within cost of product revenue, research and development and selling, general and administrative expense in the consolidated statements of comprehensive income. Intangible assets and their related useful lives are reviewed at least annually to determine if any adverse conditions exist that would indicate the carrying value of these assets may not be recoverable. More frequent impairment assessments are conducted if certain conditions exist, including a change in the competitive landscape, any internal decisions to pursue new or different technology strategies, a loss of a significant customer, or a significant change in the marketplace, including changes in the prices paid for the Company’s products or changes in the size of the market for the Company’s products. If impairment indicators are present, the Company determines whether the underlying intangible asset is recoverable through estimated future undiscounted cash flows. If the asset is not found to be recoverable, it is written down to the estimated fair value of the asset based on the sum of the future discounted cash flows expected to result from the use and disposition 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 definite-lived intangible assets are recoverable at December 31, 2021.

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

Stock Based Compensation

The Company measures stock-based compensation cost at the grant date based on the estimated fair value of the award and recognizes it as an expense over the employee’s requisite service period on a straight-line basis. The Company records the expense for share-based awards subject to performance-based milestone vesting over the remaining service period when management determines that achievement of the milestone is probable. Management evaluates whether the achievement of a performance-based milestone is probable as of the reporting date. The Company has no awards that are subject to market conditions. The Company recognizes stock-based compensation expense based upon options that are ultimately expected to vest, and accordingly, such compensation expense has been adjusted by an amount of estimated forfeitures.

The Company uses the Black-Scholes option pricing model to calculate the fair value of share-based awards on the grant date. The following assumptions are used in calculating the fair value of share-based awards:

Expected term – The expected term of options granted represents the period of time for which the options are expected to be outstanding. For purposes of estimating the expected term, the Company has aggregated all individual option awards into one group as the Company does not expect substantial differences in exercise behavior among its employees.

Expected volatility – The expected volatility is a measure of the amount by which the Company’s stock price is expected to fluctuate during the expected term of options granted. The Company determines the expected volatility based primarily upon the historical volatility of the Company’s common stock over a period commensurate with the option’s expected term.

Risk-free interest rate – The risk-free interest rate is the implied yield available on U.S. Treasury zero-coupon issues with a remaining term equal to the option’s expected term on the grant date.

Expected dividend yield – The Company has never declared or paid any cash dividends on any of its capital stock and does not expect to do so in the foreseeable future. Accordingly, the Company uses an expected dividend yield of zero to calculate the grant-date fair value of a stock option.

Estimated forfeiture rates – The Company has applied, based on an analysis of its historical forfeitures, annual forfeiture rates of 8% for awards granted to non-executive level employees, 3% for awards granted to executive level employees and 0% for awards granted to non-employee members of the Board of Directors to all unvested stock options as of December 31, 2021. The Company reevaluates this analysis periodically and adjusts these estimated forfeiture rates as necessary. Ultimately, the Company will only recognize an expense for those shares that vest.

Advertising Costs

The Company expenses advertising costs as they are incurred. Advertising expense for the years ended December 31, 2021, 2020 and 2019 was less than $0.6 million, $0.3 million and $0.1 million, respectively.

Recent Accounting Standards Updates

We consider the applicability and impact of all Accounting Standards Updates 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 Accounting Standards Updates that we feel may be applicable to the Company are as follows:

Recently Issued Accounting Standard Updates – Not Yet Adopted

In October 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-08, “Business Combinations (Topic 805) – Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” ASU 2021-08 requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, “Revenue from Contracts with Customers,” as if it had originated the contracts. This approach differs from the current requirement to measure contract assets and contract liabilities acquired in a business combination at fair value. ASU 2021-08 will be effective for us for the first quarter of 2023, with early adoption permitted. The adoption impact of the new standard will depend on the magnitude of future acquisitions. The standard will not impact acquired contract assets or liabilities from business combinations occurring prior to the adoption date.

In August 2020, the 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 does not believe the impact of the adoption of ASU 2020-06 will have a significant impact on its consolidated financial statements when adopted, beginning in the first quarter of 2022.

Fair Value Measurements

Contingent Consideration – Earnout

On September 20, 2021, the Company completed the acquisition of Avitide (the "Avitide Acquisition"), a privately-held affinity ligand discovery and development company headquartered in Lebanon, New Hampshire. The transaction consisted of upfront payments of $150.0 million and up to an additional $125.0 million (undiscounted) in contingent consideration earnout payments made equally in cash and the Company's common stock over a three-year performance period beginning January 1, 2022 and ending December 31, 2024. See Note 4, "Acquisitions" below for additional information.

A reconciliation of the change in fair value of contingent consideration – earnout is included in the following table (amounts in thousands):

Balance as of December 31, 2020 $ —
