Critical Accounting Policies and Estimates A "critical accounting policy" is one which is both important to the portrayal of our financial condition and results and requires management's most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. For a description of our critical accounting policies that affect our more significant judgments and estimates used in the preparation of our consolidated financial statements, refer to Management's Discussion and Analysis of Financial Condition and Results of Operations and our significant accounting policies in Note 2 to the consolidated financial statements included in our Form 10-K. Results of Operations The following discussion of the financial condition and results of operations should be read in conjunction with the accompanying consolidated financial statements and the related footnotes thereto. Revenues Total revenue for the three and six months endedJune 30, 2021 and 2020 were as follows: Three Months Ended Six Months Ended June 30, Increase/(Decrease) June 30, Increase/(Decrease) 2021 2020 $ Change % Change 2021 2020 $ Change % Change (Amounts in thousands, except for percentage data) Revenue: Products$ 162,920 $ 87,432 $ 75,488 86.3 %$ 305,657 $ 163,492 $ 142,165 87.0 % Royalty and other 40 30 10 33.3 % 140 60 80 133.3 % Total revenue$ 162,960 $ 87,462 $ 75,498 86.3 %$ 305,797 $ 163,552 $ 142,245 87.0 % Product revenues Direct sales represented approximately 83% and 74% of our product revenue for each of the three months endedJune 30, 2021 and 2020, respectively, and represented 82% and 75% of our product revenue for each of the six months endedJune 30, 2021 and 2020, respectively. We expect that direct sales will continue to account for an increasing percentage of our product revenues, as the largest customer of our OEM products diversified its supply chain in 2020. Sales of our bioprocessing products can be impacted by the timing of large-scale production orders and the regulatory approvals for such antibodies, which may result in significant quarterly fluctuations. 26 -------------------------------------------------------------------------------- Table of Contents Revenues from our filtration franchise include the sales of our XCell ATF ® systems and consumables, KrosFlo ® TFF and TFDF systems,TangenX ® flat sheet cassettes, ARTeSYN ® systems, and silicone-molded and plastic consumables offered by EMT and NMS. Revenues from our process analytics franchise includes the sale of our SoloVPE ® , FlowVPE ® and FlowVPX ® systems and associated consumables and service. Revenues from our chromatography franchise include the sales of our OPUS ® pre-packed columns, resins, ELISA test kits and ARTeSYN ® systems. Revenues from our proteins franchise include the sale of our Protein A ligands and cell culture growth factors. Other revenue primarily consists of sales of our operating room products to hospitals as well as freight revenue. During the three and six months endedJune 30, 2021 , product revenue increased by$75.5 million , or 86.3% and$142.2 million , or 87.0%, as compared to the same periods of 2020, with exceptionally robust demand for our filtration products. Since the second quarter of 2020, we have experienced accelerated demand across all of our franchises due to the critical needs of customers working on the novel coronavirus ("COVID-19") vaccines and therapeutics. In addition, we saw an increase in demand for gene therapy and monoclonal antibody manufacturing. Royalty revenues Royalty revenues in the three and six months endedJune 30, 2021 and 2020 relate to royalties received from a third-party systems manufacturer associated with our OPUS PD chromatography columns. Royalty revenues are variable and are dependent on sales generated by our partner. Costs of product revenue and operating expenses Total costs and operating expenses for the three and six months endedJune 30, 2021 and 2020 were comprised of the following: Three Months Ended Six Months Ended June 30, Increase/(Decrease) June 30, Increase/(Decrease) 2021 2020 $ Change % Change 2021 2020 $ Change % Change (Amounts in thousands, except for percentage data) Cost of product revenue$ 61,990 $ 36,863 $ 25,127 68.2 %$ 121,737 $ 68,845 $ 52,892 76.8 % Research and development 8,389 4,336 4,053 93.5 % 16,001 9,038 6,963

Total costs and operating expenses$ 114,720 $ 67,925 $ 46,795 68.9 %$ 221,174 $ 132,109 $ 89,065 67.4 % Cost of product revenue Cost of product revenue increased 68.2% and 76.8% in the three and six months endedJune 30, 2021 , compared to the same periods of 2020, due primarily to the increase in product revenue mentioned above and costs associated with higher product volume. In addition, there was an increase in manufacturing headcount for the three and six months endedJune 30, 2021 , as compared to the same periods of 2020, which resulted in higher employee-related costs. We completed acquisitions during the second half of 2020, which resulted in an increase in costs of product revenue during these periods in 2021 as well, for which there were no comparable amounts during 2020. Gross margin was 62.0% and 60.2% in the three and six months endedJune 30, 2021 . The gross margin for the six months endedJune 30, 2021 includes$1.6 million of amortization of inventory step-up associated with the ARTeSYN Acquisition. The gross margin for the six months endedJune 30, 2020 was 57.9%. Excluding the step-up amortization, gross margin for the six months endedJune 30, 2021 was 60.7%. The increase in gross margin, excluding the inventory step-up amortization, in the six months endedJune 30, 2021 , as compared to the same period of 2020, is due primarily to the increase in revenue mentioned above, and favorable product mix, partially offset by an increase in manufacturing headcount subsequent toJune 30, 2020 . Gross margins may fluctuate in future quarters based on expected production volume and product mix. 27 -------------------------------------------------------------------------------- Table of Contents 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 93.5% during the three months endedJune 30, 2021 , compared to the same period of 2020. The increase during the period is primarily due to the addition of$1.0 million of R&D expenses incurred by ARTeSYN during the period, for which there were not comparable costs in 2020, and due to the increase in employee related costs as the number of R&D employees has increased sinceJune 30, 2020 . R&D expenses increased 77.0% during the six months endedJune 30, 2021 , compared to the same period of 2020. The increase during the period is due to the addition of$2.1 million in R&D expenses related to ARTeSYN's operations and increased costs associated with an increase in R&D headcount and the ramp up of project spending for new product development during the first half of 2021. We expect our R&D expenses for the remainder of 2021 to gradually increase to support new product development. Selling, general and administrative expenses Selling, general and administrative ("SG&A") expenses include the costs associated with selling our commercial products and costs required to support our marketing efforts, including legal, accounting, patent, shareholder services, amortization of intangible assets and other administrative functions. During the three and six months endedJune 30, 2021 , SG&A costs increased by$17.6 million , or 65.9%, and$29.2 million , or 53.9%, as compared to the same periods of 2020. The increase is partially due to the continued expansion of our customer-facing activities to drive sales of our bioprocessing products, and the continued buildout of our administrative infrastructure, primarily through increased headcount, to support expected future growth. Stock-based compensation expense and other employee-related costs increased during the three and six months endedJune 30, 2021 , as compared to the same period in 2020, resulting from an increase in headcount period over period. In addition,$3.6 million and$6.8 million of the increase in SG&A costs for the three and six months endedJune 30, 2021 , respectively, was related to the addition of EMT, NMS and ARTeSYN during the second half of 2020 for which there were no comparable amounts for the same periods of 2020. Other expenses, net The table below provides detail regarding our other expenses, net: Three Months Ended Six Months Ended June 30, Increase/(Decrease) June 30, Increase/(Decrease) 2021 2020 $ Change % Change 2021 2020 $ Change % Change

The decrease of$0.2 million and$1.5 million in the three and six months endedJune 30, 2021 , as compared to the same periods of 2020, was attributable to a decrease in interest rates on our invested cash balances. InMarch 2020 , in response to the outbreak of COVID-19 and to stay ahead of disruptions and economic slowdown, theFederal 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. 28 -------------------------------------------------------------------------------- Table of Contents Interest expense Interest expense in the three and six months endedJune 30, 2021 and 2020 is primarily from our 0.375% Convertible Senior Notes due 2024 (the "2019 Notes"), which were issued inJuly 2019 . Interest expense, which includes the amortization of debt issuance costs and contractual coupon interest, increased$0.1 million and$0.3 million for the three and six months endedJune 30, 2021 , as compared to the same periods in 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. Other expenses The change in other expenses, net during the three and six months endedJune 30, 2021 , compared to the same period of 2020, is primarily attributable to realized foreign currency losses related to amounts due from non-Swedish krona-based customers and vendors. Income tax provision Income tax provision for the three and six months endedJune 30, 2021 and 2020 was as follows: Three Months Ended Six Months Ended June 30, Increase/(Decrease) June 30, Increase/(Decrease) 2021 2020 $ Change % Change 2021 2020 $ Change % Change (Amounts in thousands, except for percentage data) Income tax provision$ 8,125 $ 159 $ 7,966 5010.1 %$ 11,780 $ 1,020 $ 10,760 1054.9 % Effective tax rate 18.3 % 1.0 % 15.2 % 3.8 % For the three and six months endedJune 30, 2021 , we recorded an income tax provision of$8.1 million and$11.8 million , respectively. The effective tax rate was 18.3% and 15.2% for the three and six months endedJune 30, 2021 and is based upon the estimated income for the year endingDecember 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 lowerU.S. taxation of foreign earnings. The effective tax rate for the three and six months endedJune 30, 2021 was lower than theU.S. statutory rate of 21% primarily due to business tax credits and windfall benefits on stock option exercises and the vesting of stock units. For the three and six months endedJune 30, 2020 , we recorded an income tax provision of$0.2 million and$1.0 million , respectively. The effective tax rate was 1.0% and 3.8% for the three and six months endedJune 30, 2020 and is based upon the estimated income for the year endingDecember 31, 2020 and the composition of income in different jurisdictions. The effective tax rate for the three and six months endedJune 30, 2020 was lower than theU.S. statutory rate of 21% primarily due to windfall benefits on stock option exercise and the vesting of stock units. Non-GAAP Financial Measures We provide non-GAAP adjusted income from operations; adjusted net income; and adjusted EBITDA as supplemental measures to GAAP measures regarding our operating performance. These financial measures exclude the items detailed below and, therefore, have not been calculated in accordance with GAAP. A detailed explanation and a reconciliation of each non-GAAP financial measure to its most comparable GAAP financial measure are provided below. We include this financial information because we believe these measures provide a more accurate comparison of our financial results between periods and more accurately reflect how management reviews its financial results. We excluded the impact of certain acquisition-related items because we believe that the resulting charges do not accurately reflect the performance of our ongoing operations for the period in which such charges are incurred. Non-GAAP adjusted income from operations Non-GAAP adjusted income from operations is measured by taking income from operations as reported in accordance with GAAP and excluding inventory step-up charges, acquisition and integration costs, and intangible amortization booked through our consolidated statements of comprehensive income.

Our revenue for the foreseeable future will primarily be limited to our bioprocessing product revenue. AtJune 30, 2021 , we had cash and cash equivalents (excluding restricted cash) of$734.3 million compared to cash and cash equivalents (excluding restricted cash) of$717.3 million atDecember 31, 2020 . During the second quarter of 2021, the closing price of the Company's common stock exceeded 130% of the conversion price of the 2019 Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the 2019 Notes are convertible at the option of the holders of the 2019 Notes during the third quarter of 2021, the quarter immediately following the quarter when the conditions are met, per the First Supplemental Indenture underlying the 2019 Notes. These conditions were also met during the fourth quarter of 2020 and the first quarter of 2021. As a result, the Company received notices from note holders that they would convert$6,000 aggregate principal amount of the 2019 Notes, of which$1,000 principal were settled during the first quarter of 2021,$4,000 principal were settled during the second quarter of 2021 and$1,000 principal will be settled during the third quarter of 2021. The conversions resulted in the issuance of a nominal number of shares of the Company's common stock to the holder, and the Company recorded a loss of approximately$4,000 on the conversion of these notes, which is included in other expenses, net on our consolidated statements of comprehensive income for the three and six months endedJune 30, 2021 . The 2019 Notes have a face value of$287.5 million and a carrying value and a carrying value of$249.4 million and continue to be classified as current liabilities on the Company's consolidated balance sheet as ofJune 30, 2021 . It is the Company's policy and intent to settle the face value of the 2019 Notes in cash and any excess conversion premium in shares of our common stock. InJuly 2020 , the Company entered into a First Amendment to the lease agreement for itsMarlborough, Massachusetts facility, expanding the leased space by 66,939 square feet. InDecember 2020 , the Company signed the Second Amendment to the lease agreement, changing the commencement date fromApril 1, 2021 toJanuary 1, 2021 . As a result, under the amended lease agreement, the Company will pay an additional$5.7 million in base rent over the life of the lease, which expires onNovember 30, 2028 . 31 -------------------------------------------------------------------------------- Table of Contents InMay 2021 , the Company entered into an agreement to lease approximately 64,000 square feet of space at a site inHopkinton, Massachusetts , which expires onAugust 15, 2034 .

An increase in accounts receivable consumed$31.9 million of cash and was primarily driven by the 87.0% year-to-date increase in revenues. An increase in inventory manufactured of$42.8 million supports expected increases in future revenue. The increases in accounts receivable and inventory manufactured are offset by an increase in accounts payable of$8.3 million , which was primarily due to increased inventory purchases to support customer orders, an increase in accrued liabilities of$4.5 million , which was due to an increase in the accrual for expected costs, and to a decrease in deferred revenue related to products shipped during the first half of 2021. The remaining cash used in operating activities resulted from unfavorable changes in various other working capital accounts. For the six months endedJune 30, 2020 , our operating activities provided cash of$26.3 million reflecting net income of$25.7 million and non-cash charges totaling$24.8 million primarily related to depreciation, amortization, deferred income taxes, non-cash interest expense and stock-based compensation charges. An increase in accounts receivable consumed$6.0 million of cash and was primarily driven by the 24.5% year-to-date increase in revenues. An increase in inventory consumed$15.0 million to support future revenue. A decrease in accounts payable and accrued liabilities of$4.1 million was due primarily to the payment of the$9.0 million to employees during the second quarter of 2020 for C Technologies acquisition-related bonuses. The remaining cash provided by operating activities resulted from favorable changes in various other working capital accounts. Investing activities Our investing activities consumed$26.2 million of cash during the six months endedJune 30, 2021 , primarily related to the ongoing capital expenditures as we continue to increase our manufacturing capacity worldwide.

Table of Contents Our future capital requirements will depend on many factors, including the following:
• the expansion of our bioprocessing business;
• the ability to sustain sales and profits of our bioprocessing products;
• our ability to acquire additional bioprocessing products; • the scope of and progress made in our R&D activities; • the extent of any share repurchase activity; and • the success of any proposed financing efforts. Absent acquisitions of additional products, product candidates or intellectual property, we believe our current cash balances are adequate to meet our cash needs for at least the next 24 months from the date of this filing. We expect operating expenses for the rest of the year to increase as we continue to expand our bioprocessing business. We expect to incur continued spending related to the development and expansion of our bioprocessing product lines and expansion of our commercial capabilities for the foreseeable future. Our future capital requirements may include, but are not limited to, purchases of property, plant and equipment, the acquisition of additional bioprocessing products and technologies to complement our existing manufacturing capabilities, and continued investment in our intellectual property portfolio. We plan to continue to invest in our bioprocessing business and in key R&D activities associated with the development of new bioprocessing products. We actively evaluate various strategic transactions on an ongoing basis, including licensing or acquiring complementary products, technologies or businesses that would complement our existing portfolio. We continue to seek to acquire such potential assets that may offer us the best opportunity to create value for our shareholders. In order to acquire such assets, we may need to seek additional financing to fund these investments. If our available cash balances and anticipated cash flow from operations are insufficient to satisfy our liquidity requirements, including because of any such acquisition-related financing needs or lower demand for our products, we may seek to sell common or preferred equity or convertible debt securities, enter into a credit facility or another form of third-party funding, or seek other debt funding. The sale of equity and convertible debt securities may result in dilution to our shareholders, and those securities may have rights senior to those of our common shares. If we raise additional funds through the issuance of preferred stock, convertible debt securities or other debt financing, these securities or other debt could contain covenants that would restrict our operations. Any other third-party funding arrangement could require us to relinquish valuable rights. We may require additional capital beyond our currently anticipated amounts. Additional capital may not be available on reasonable terms, if at all. Off-Balance Sheet Arrangements We do not have any special purpose entities or off-balance sheet financing arrangements as ofJune 30, 2021 . Net Operating Loss Carryforwards AtDecember 31, 2020 , we had net operating loss carryforwards of$6.4 million remaining. We had business tax credits carryforwards of$9.4 million available to reduce future federal income taxes, if any. The business tax credits carryforwards will continue to expire at various dates throughDecember 2039 . Net operating loss carryforwards and available tax credits are subject to review and possible adjustment by the Internal Revenue Service, state and foreign jurisdictions and may be limited in the event of certain changes in the ownership interest of significant shareholders. Effects of Inflation Our assets are primarily monetary, consisting of cash, cash equivalents and marketable securities. Because of their liquidity, these assets are not directly affected by inflation. Since we intend to retain and continue to use our equipment, furniture and fixtures and leasehold improvements, we believe that the incremental inflation related to replacement costs of such items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase our level of expenses and the rate at which we use our resources. 33
