Words such as “anticipate,” “expect,” “intend,” “plan,” “believe,” “seek,” “estimate,” variations of such words, and similar expressions are intended to identify such forward - looking statements, although not all forward - looking statements contain these identifying words . These statements concern, and these risks and uncertainties include, among others, the impact of SARS - CoV - 2 (the virus that has caused the COVID - 19 pandemic) on Regeneron's business and its employees, collaborators, and suppliers and other third parties on which Regeneron relies, Regeneron's and its collaborators’ ability to continue to conduct research and clinical programs, Regeneron's ability to manage its supply chain, net product sales of products marketed or otherwise commercialized by Regeneron and/or its collaborators or licensees (collectively, ”Regeneron’s Products“), and the global economy ;

safety issues resulting from the administration of Regeneron’s Products and Regeneron’s Product Candidates in patients, including serious complications or side effects in connection with the use of Regeneron’s Products and Regeneron’s Product Candidates in clinical trials ; the likelihood, timing, and scope of possible regulatory approval and commercial launch of Regeneron’s Product Candidates and new indications for Regeneron’s Products, including without limitation those listed above ; the likelihood and timing of achieving any of the anticipated milestones described in this presentation ; the extent to which the results from the research and development programs conducted by Regeneron and/or its collaborators or licensees may be replicated in other studies and/or lead to advancement of product candidates to clinical trials, therapeutic applications, or regulatory approval ; ongoing regulatory obligations and oversight impacting Regeneron’s Products, research and clinical programs, and business, including those relating to patient privacy ; determinations by regulatory and administrative governmental authorities which may delay or restrict Regeneron’s ability to continue to develop or commercialize Regeneron’s Products and Regeneron’s Product Candidates ; competing drugs and product candidates that may be superior to, or more cost effective than, Regeneron’s Products and Regeneron’s Product Candidates ; uncertainty of the utilization, market acceptance, and commercial success of Regeneron’s Products and Regeneron’s Product Candidates and the impact of studies (whether conducted by Regeneron or others and whether mandated or voluntary) or recommendations and guidelines from governmental authorities and other third parties on the commercial success of Regeneron’s Products and Regeneron’s Product Candidates ; the availability and extent of reimbursement of Regeneron’s Products from third - party payors, including private payor healthcare and insurance programs, health maintenance organizations, pharmacy benefit management companies, and government programs such as Medicare and Medicaid ; coverage and reimbursement determinations by such payors and new policies and procedures adopted by such payors ; the ability of Regeneron to manufacture and manage supply chains for multiple products and product candidates ; the ability of Regeneron’s collaborators, licensees, suppliers, or other third parties (as applicable) to perform manufacturing, filling, finishing, packaging, labeling, distribution, and other steps related to Regeneron’s Products and Regeneron’s Product Candidates ; unanticipated expenses ; the costs of developing, producing, and selling products ; the ability of Regeneron to meet any of its sales or other financial projections or guidance and changes to the assumptions underlying those projections or guidance ; risks associated with intellectual property of other parties and pending or future litigation relating thereto (including without limitation the patent litigation and other related proceedings relating to EYLEA, Dupixent, Praluent, and REGEN - COV), other litigation and other proceedings and government investigations relating to the Company and/or its operations, the ultimate outcome of any such proceedings and investigations, and the impact any of the foregoing may have on Regeneron’s business, prospects, operating results, and financial condition ; and the potential for any license or collaboration agreement, including Regeneron’s agreements with Sanofi, Bayer, and Teva Pharmaceutical Industries Ltd . (or their respective affiliated companies, as applicable), as well as Regeneron's agreement with Roche relating to the casirivimab and imdevimab antibody cocktail (known as REGEN - COV in the United States and Ronapreve Œ in other countries) and its REGEN - COV supply agreement with the U . S . government, to be cancelled or terminated . A more complete description of these and other material risks can be found in Regeneron’s filings with the U . S . Securities and Exchange Commission . Any forward - looking statements are made based on management’s current beliefs and judgment, and the reader is cautioned not to rely on any forward - looking statements made by Regeneron . Regeneron does not undertake any obligation to update (publicly or otherwise) any forward - looking statement, including without limitation any financial projection or guidance, whether as a result of new information, future events, or otherwise . This presentation uses total revenues excluding REGEN - COV, which is a financial measure that is not calculated in accordance with U . S . Generally Accepted Accounting Principles (“GAAP”) . This and other non - GAAP financial measures are computed by excluding certain non - cash and other items from the related GAAP financial measure . Non - GAAP adjustments also include the income tax effect of reconciling items . The Company makes such adjustments for items the Company does not view as useful in evaluating its operating performance . For example, adjustments may be made for items that fluctuate from period to period based on factors that are not within the Company’s control, such as the Company’s stock price on the dates share - based grants are issued . Management uses non - GAAP measures for planning, budgeting, forecasting, assessing historical performance, and making financial and operational decisions, and also provides forecasts to investors on this basis . Additionally, non - GAAP measures provide investors with an enhanced understanding of the financial performance of the Company’s core business operations . However, there are limitations in the use of non - GAAP financial measures as they exclude certain expenses that are recurring in nature . Furthermore, the Company’s non - GAAP financial measures may not be comparable with non - GAAP information provided by other companies . Any non - GAAP financial measure presented by Regeneron should be considered supplemental to, and not a substitute for, measures of financial performance prepared in accordance with GAAP . A reconciliation of the non - GAAP financial measure used in this presentation is provided on slide 28 . Note regarding forward - looking statements & non - GAAP financial measures
