Forward-Looking Statements & Use of Non-GAAP Reporting Forward-looking Statements. Some statements in this presentation may be forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, without limitation, statements regarding management’s goals, plans, and expectations, our future financial performance, our future financial projections, our growth strategy, and other matters. Forward looking statements generally can be identified by the use of forward-looking terminology such as, “anticipate,” “believe,” “expect,” “assume,” “continue,” “may,” “will,” “intend,” “estimate,” or similar expressions or the negative of those terms or expressions, although not all forward-looking statements contain these words. These statements are based on assumptions and expectations of future events that are subject to risks and uncertainties. Included in these forward-looking statements are statements regarding the impact of the COVID-19 pandemic on Bio-Rad’s results and operations. Our actual results may differ materially from these plans and expectations, and the impact and duration of the COVID-19 pandemic is unknown. Undue reliance should not be placed on these forward-looking statements, and it is encouraged to review our SEC filings, where the risk factors in our business are discussed in detail. The forward-looking statements contained in this presentation reflect our views and assumptions only as of the date of this presentation. While we may elect to update forward-looking statements at some point in the future, we specifically disclaim any obligation to do so, even if estimates change, so you should not rely on these forward-looking statements as representing our views as of any date other than the date of this presentation. Use of Non-GAAP Reporting and Currency-Neutral. In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use certain non-GAAP financial measures, including non-GAAP revenue, non-GAAP gross margin, non-GAAP adjusted EBITDA, and non-GAAP adjusted EBITDA margin, which exclude amortization of acquisition-related intangible assets, certain acquisition-related expenses and benefits, restructuring charges, asset impairment charges, valuation changes of equity-owned securities, gains and losses on equity-method investments, and significant legal-related charges or benefits and associated legal costs. Non-GAAP revenue, non-GAAP gross margin, non-GAAP adjusted EBITDA, and non-GAAP adjusted EBITDA margin also exclude certain other gains and losses that are either isolated or cannot be expected to occur again with any predictability, tax provisions/benefits related to the previous items, and significant discrete tax events. We exclude the above items because they are outside of our normal operations and/or, in certain cases, are difficult to forecast accurately for future periods. We utilize a number of different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of our business, in making operating decisions, forecasting and planning for future periods, and determining payments under compensation programs. We consider the use of the non-GAAP measures to be helpful in assessing the performance of the ongoing operation of our business. We believe that disclosing non-GAAP financial measures provides useful supplemental data that, while not a substitute for financial measures prepared in accordance with GAAP, allows for greater transparency in the review of our financial and operational performance. We also believe that disclosing non-GAAP financial measures provides useful information to investors and others in understanding and evaluating our operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies. More specifically, management adjusts for the excluded items for the following reasons: Amortization of purchased intangible assets: we do not acquire businesses and assets on a predictable cycle. The amount of purchase price allocated to purchased intangible assets and the term of amortization can vary significantly and are unique to each acquisition or purchase. We believe that excluding amortization of purchased intangible assets allows the users of our financial statements to better review and understand the historic and current results of our operations, and also facilitates comparisons to peer companies. Acquisition-related expenses and benefits: we incur expenses or benefits with respect to certain items associated with our acquisitions, such as transaction costs, professional fees for assistance with the transaction; valuation or integration costs; changes in the fair value of contingent consideration, gain or loss on settlement of pre-existing relationships with the acquired entity; or adjustments to purchase price. We exclude such expenses or benefits as they are related to acquisitions and have no direct correlation to the operation of our on-going business. Restructuring, impairment charges and valuation changes in equity-owned securities and gains and losses on equity-method investments: we incur restructuring and impairment charges on individual or groups of employed assets and charges and benefits arising from valuation changes in equity-owned securities and gains and losses on equity-method investments, which arise from unforeseen circumstances and/or often occur outside of the ordinary course of our on-going business. Although these events are reflected in our GAAP financials, these unique transactions may limit the comparability of our on-going operations with prior and future periods. Significant litigation charges or benefits and legal costs: we may incur charges or benefits as well as legal costs in connection with litigation and other contingencies unrelated to our core operations. We exclude these charges or benefits, when significant, as well as legal costs associated with significant legal matters, because we do not believe they are reflective of on-going business and operating results. Income tax expense: we estimate the tax effect of the excluded items identified above to determine a non-GAAP annual effective tax rate applied to the pretax amount in order to calculate the non-GAAP provision for income taxes. We also adjust for items for which the nature and/or tax jurisdiction requires the application of a specific tax rate or treatment. From time to time in the future, there may be other items excluded if we believe that doing so is consistent with the goal of providing useful information to investors and management. Percentage sales growth in currency neutral amounts are calculated by translating prior period sales in each local currency using the current period’s monthly average foreign exchange rates for that currency and comparing that to current period sales. There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with generally accepted accounting principles and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact on our reported financial results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP in the United States. Non-GAAP adjusted EBITDA includes an annual dividend from our investment in Sartorius AG. Investors should review the reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this presentation. In addition, for 2020 and 2021 we have presented information about core revenue, which we define as currency neutral non-GAAP revenue and excludes COVID related sales. We present this core revenue measure since we think it is helpful for understanding the performance of the rest of our business excluding COVID related sales. In 2020 and 2021, COVID related sales were approximately $318 million and $266 million respectively. COVID related sales for Life Science in 2020 and 2021 were approximately $311 million and $247.1 million respectively, and Covid related sales for Clinical Diagnostics in 2020 and 2021 were approximately $7 million and $18.6 million respectively. Free cash flow is a non-GAAP measure and is defined as cash flow from operations minus net capital expenditures. We believe free cash flow is a helpful financial metric for use in evaluating the company’s financial performance since it measures our ability to generate additional cash from our business operations. We do not provide a reconciliation of our non-GAAP financial expectations to expectations for the most comparable GAAP measure because the amount and timing of many future charges that impact these measures (such as amortization of future acquisition-related intangible assets, future acquisition-related expenses and benefits, future restructuring charges, future asset impairment charges, future valuation changes of equity-owned securities, future gains and losses on equity -method investments or future legal charges or benefits), which could be material, are variable, uncertain, or out of our control and therefore cannot be reasonably predicted without unreasonable effort, if at all. Additional Disclosures. The data included in this presentation regarding markets and the industry in which we operate, including the size of certain markets, are based on publicly available information and published industry sources. In presenting this information, we have also made certain estimates and assumptions that we believe to be reasonable based on the information referred to above and similar sources, as well as our internal research, calculations and assumptions based on our analysis of such information and our knowledge of, and our experience to date in, our industries and markets. Market share data is subject to change and may be limited by the availability of raw data, the voluntary nature of the data gathering process and other limitations inherent in any statistical survey of market share data. Accordingly, you are cautioned not to place undue reliance on such market share data or any other such estimates. While we believe such information is reliable, we cannot guarantee the accuracy or completeness of this information.
