(NASDAQ: REGN) today announced financial results for the first quarter of 2024 and provided a business update. "The Regeneron team has already made substantial progress this year, delivering our approved medicines to more patients around the globe, advancing our pipeline consisting of dozens of clinical-stage programs, and relentlessly pursuing cutting-edge science," said Leonard S. Schleifer, M.D., Ph.D., Board co-Chair, President and Chief Executive Officer of Regeneron. "We had a strong quarter of EYLEA HD uptake, and we are well positioned to continue our leadership in retinal diseases. Dupixent continues to grow at a remarkable pace seven years into its launch and is currently treating over 850,000 patients across a variety of diseases characterized by type 2 inflammation. Our promising oncology franchise is strengthening, driven by strong global growth in Libtayo sales and potential regulatory approvals later this year for linvoseltamab in relapsed/refractory multiple myeloma." Financial Highlights ($ in millions, except per share data) Q1 2024 Q1 2023 % Change Total revenues $ 3,145 $ 3,162 (1% ) Total revenues excluding Ronapreve(a)(b) $ 3,145 $ 2,940 7% GAAP net income $ 722 $ 818 (12% ) GAAP net income per share - diluted $ 6.27 $ 7.17 (13% ) Non-GAAP net income(a) $ 1,116 $ 1,168 (4% ) Non-GAAP net income per share - diluted(a) $ 9.55 $ 10.09 (5% ) "We are off to a strong start in 2024 as reflected in our solid first quarter financial results and the progress we have made across our growing pipeline," said Christopher Fenimore, Senior Vice President, Finance and Chief Financial Officer of Regeneron. "While investing in innovation remains our top capital allocation priority, the recent authorization by Regeneron's board of directors of a new $3.0 billion share repurchase program provides us with additional flexibility to continue returning capital to shareholders over time." Business Highlights Key Pipeline Progress Regeneron has over 35 product candidates in clinical development, including a number of marketed products for which it is investigating additional indications. Updates from the clinical pipeline include: EYLEA HD (aflibercept) 8 mg In January 2024, the European Commission (EC) and Japan's Ministry of Health, Labour and Welfare (MHLW) each approved EYLEA 8 mg (known as EYLEA HD in the United States) for the treatment of patients with wet age-related macular degeneration (wAMD) and diabetic macular edema (DME). In January 2024, the United States Centers for Medicare & Medicaid Services (CMS) assigned a permanent and product-specific J-code (J0177) for EYLEA HD, which became effective on April 1, 2024. J-codes simplify and streamline the billing and reimbursement processes for Medicare Part B treatments, allowing for efficient claims processing. Dupixent (dupilumab) The U.S. Food and Drug Administration (FDA) accepted for priority review the supplemental Biologics License Application (sBLA) for Dupixent as an add-on maintenance treatment in adult patients with uncontrolled chronic obstructive pulmonary disease (COPD) and evidence of type 2 inflammation. A regulatory application is also under review in the European Union (EU) and Japan. A Phase 3 study for Dupixent in asthma for children aged 2 to 5 years was initiated. In February 2024, the MHLW in Japan approved Dupixent for the treatment of chronic spontaneous urticaria (CSU) in adults and children aged 12 years and older whose disease is not adequately controlled with existing therapy. A regulatory application has also been submitted in the EU. Oncology Programs The FDA accepted the BLA seeking accelerated approval for linvoseltamab, a bispecific antibody targeting BCMA and CD3, to treat adult patients with relapsed/refractory (R/R) multiple myeloma that has progressed after at least three prior therapies, and the BLA was granted priority review with a target action date of August 22, 2024. A Phase 3 confirmatory trial is currently enrolling patients. A regulatory application is also under review in the EU. In April 2024, the Company presented positive pivotal data from the Phase 1/2 trial of linvoseltamab in patients with R/R multiple myeloma at the American Association for Cancer Research (AACR) Annual Meeting 2024. The linvoseltamab data reinforced previously shared findings and included a 71% objective response rate (ORR), with 46% of patients achieving a complete response (CR) or better. In March 2024, the FDA issued Complete Response Letters (CRLs) for the BLA for odronextamab, a bispecific antibody targeting CD20 and CD3, in R/R follicular lymphoma (FL) and R/R diffuse large B-cell lymphoma (DLBCL). The only approvability issue cited in the CRLs is related to the enrollment status of the confirmatory trials. The CRLs (one for R/R FL and one for R/R DLBCL) did not identify any approvability issues with the clinical efficacy or safety, trial design, labeling, or manufacturing. A regulatory application for R/R DLBCL and R/R FL remains under review in the EU. In 2023, the Company initiated a Phase 2/3 study of the combination of fianlimab, an antibody to LAG-3, and Libtayo (cemiplimab) in first-line metastatic melanoma. This study is enrolling faster than expected and will be conducted solely as a Phase 3 study with the final analysis to be reported during 2025. Other Programs The FDA has extended the approval of Praluent® (alirocumab) as an adjunct to diet and other low-density lipoprotein cholesterol (LDL-C) lowering therapies to include pediatric patients aged 8 years and older with heterozygous familial hypercholesterolemia (HeFH). A Phase 2 study for itepekimab, an antibody to IL-33, for non-cystic fibrosis bronchiectasis (NCFB) was initiated. A Phase 2 study for ALN-APP, an investigational RNAi therapeutic targeting amyloid precursor protein (APP), was initiated by the Company's collaborator Alnylam Pharmaceuticals, Inc. in patients with cerebral amyloid angiopathy (CAA). Corporate and Business Development Updates In April 2024, the Company acquired full development and commercialization rights to 2seventy bio, Inc.'s oncology and autoimmune preclinical and clinical stage cell therapy pipeline. Under the terms of the agreement, the Company made a $5 million up-front payment, and has assumed ongoing program, infrastructure, and personnel costs related to the product candidates acquired. In addition, the Company is obligated to pay 2seventy bio a regulatory milestone upon the first major market approval of the first approved product; and, with respect to any approved product, a low single-digit percent royalty on sales. In April 2024, the Company and Mammoth Biosciences, Inc. entered into a collaboration agreement to research, develop, and commercialize in vivo CRISPR-based gene editing therapies for multiple tissues and cell types. Under the terms of the agreement, the Company purchased an aggregate of $95 million of Mammoth preferred stock and is obligated to make a $5 million up-front payment. The parties will jointly select and research collaboration targets, and then Regeneron will lead development and commercialization. In April 2024, the Company's board of directors authorized a new share repurchase program to repurchase up to an additional $3.0 billion of the Company's common stock. Repurchases may be made from time to time at management's discretion through a variety of methods. The program has no time limit and can be discontinued at any time. First Quarter 2024 Financial Results Revenues ($ in millions) Q1 2024 Q1 2023 % Change Net product sales: EYLEA HD - U.S. $ 200 $ — * EYLEA - U.S. 1,202 1,434 (16% ) Total EYLEA HD and EYLEA - U.S. 1,402 1,434 (2% ) Libtayo - Global 264 177 49% Praluent - U.S. 70 40 75% Evkeeza® - U.S. 24 15 60% Inmazeb® - Global 1 2 * Total net product sales 1,761 1,668 6% Collaboration revenue: Sanofi 910 798 14% Bayer 356 357 —% Other 1 223 (100% ) Other revenue 117 116 1% Total revenues $ 3,145 $ 3,162 (1% ) * Percentage not meaningful Net product sales of EYLEA in the U.S. decreased in the first quarter of 2024, compared to the first quarter of 2023, primarily due to changing market dynamics, resulting in lower volumes and a lower net selling price. In addition, aggregate net product sales of EYLEA and EYLEA HD in the first quarter of 2024 were negatively impacted by approximately $40 million due to a sequential net reduction in wholesaler inventory. Sanofi collaboration revenue increased in the first quarter of 2024, compared to the first quarter of 2023, primarily due to the Company's share of profits from commercialization of antibodies, which were $804 million in the first quarter of 2024, compared to $637 million in the first quarter of 2023. The change in the Company's share of profits from commercialization of antibodies was driven by higher profits associated with an increase in Dupixent sales. The decrease in other collaboration revenue in the first quarter of 2024, compared to the first quarter of 2023, was due to lower sales of Ronapreve. Under the Company's Roche collaboration agreement, the Company records collaboration revenue in connection with payments from Roche attributable to gross profits from sales of Ronapreve; however, the Company does not expect any additional Roche collaboration revenue from Ronapreve in future periods. Refer to Table 4 for a summary of collaboration revenue.

Acquired IPR&D for first quarter of 2023 included a $45 million up-front payment in connection with the Company's collaboration agreement with Sonoma Biotherapeutics, Inc. GAAP and non-GAAP SG&A expenses increased in the first quarter of 2024, compared to the first quarter of 2023, due to higher commercialization-related expenses to support the Company's launch of EYLEA HD and higher headcount and headcount-related costs primarily related to the international expansion in support of Libtayo and hematology product launch preparations. GAAP and non-GAAP COGS increased in the first quarter of 2024, compared to the first quarter of 2023, primarily due to higher start-up costs for the Company's Rensselaer, New York fill/finish facility. COCM decreased in the first quarter of 2024, compared to the first quarter of 2023, primarily due to lower Dupixent manufacturing costs as a result of the transition to a higher-yielding manufacturing process. GAAP other operating expense (income), net, for the first quarter of 2024 reflects a charge related to the increase in the estimated fair value of the contingent consideration liability recognized in connection with the Company's 2023 acquisition of Decibel Therapeutics, Inc. Other Financial Information GAAP other income (expense) included the recognition of net unrealized losses on equity securities of $196 million in the first quarter of 2024, compared to $165 million of net unrealized losses in the first quarter of 2023. GAAP and Non-GAAP other income (expense) also included interest income of $162 million in the first quarter of 2024, compared to $95 million in the first quarter of 2023. In the first quarter of 2024, the Company's GAAP effective tax rate (ETR) was (3.0%), compared to 4.7% in the first quarter of 2023. The GAAP ETR in the first quarter of 2024, compared to the first quarter of 2023, included a higher benefit from stock-based compensation. In the first quarter of 2024, the non-GAAP ETR was 6.1%, compared to 9.7% in the first quarter of 2023. GAAP net income per diluted share was $6.27 in the first quarter of 2024, compared to $7.17 in the first quarter of 2023. Non-GAAP net income per diluted share was $9.55 in the first quarter of 2024, compared to $10.09 in the first quarter of 2023. A reconciliation of the Company's GAAP to non-GAAP results is included in Table 3 of this press release. During the first quarter of 2024, the Company repurchased shares of its common stock and recorded the cost of the shares, or $298 million, as Treasury Stock. As of March 31, 2024, $1.2 billion remained available for share repurchases under the Company's share repurchase program then in effect (excluding the additional $3.0 billion share repurchase program authorized in April 2024). 2024 Financial Guidance(c) The Company's full year 2024 financial guidance consists of the following components: 2024 Guidance Prior Updated GAAP R&D $4.820–$5.070 billion $4.920–$5.170 billion** Non-GAAP R&D(a) $4.300–$4.500 billion $4.400–$4.600 billion** GAAP SG&A $2.890–$3.090 billion $2.940–$3.090 billion Non-GAAP SG&A(a) $2.500–$2.650 billion $2.550–$2.650 billion GAAP gross margin on net product sales(d) 86%–88% Unchanged Non-GAAP gross margin on net product sales(a)(d) 89%–91% Unchanged COCM(e)* $850–$910 million Unchanged Capital expenditures* $825–$950 million $780–$880 million GAAP effective tax rate 8%–10% 7%–9% Non-GAAP effective tax rate(a) 10%–12% Unchanged * GAAP and non-GAAP amounts are equivalent as no non-GAAP adjustments have been or are expected to be recorded. ** Updates to GAAP and non-GAAP amounts reflect ongoing program, infrastructure, and personnel costs assumed in connection with the acquisition of 2seventy bio's preclinical and clinical pipeline as described above. A reconciliation of full year 2024 GAAP to non-GAAP financial guidance is included below: Projected Range ($ in millions) Low High GAAP R&D $ 4,920 $ 5,170 Stock-based compensation expense 510 540 Acquisition and integration costs 10 30 Non-GAAP R&D $ 4,400 $ 4,600 GAAP SG&A $ 2,940 $ 3,090 Stock-based compensation expense 350 380 Acquisition and integration costs 40 60 Non-GAAP SG&A $ 2,550 $ 2,650 GAAP gross margin on net product sales 86% 88% Stock-based compensation expense 1% 1% Intangible asset amortization expense 1% 1% Acquisition and integration costs <1% <1% Non-GAAP gross margin on net product sales 89% 91% GAAP ETR 7% 9% Income tax effect of GAAP to non-GAAP reconciling items 3% 3% Non-GAAP ETR 10% 12% (a) This press release uses non-GAAP R&D, non-GAAP SG&A, non-GAAP COGS, non-GAAP gross margin on net product sales, non-GAAP other operating (income) expense, net, non-GAAP other income (expense), net, non-GAAP ETR, non-GAAP net income, non-GAAP net income per share, total revenues excluding Ronapreve, and free cash flow, which are financial measures that are not calculated in accordance with U.S. Generally Accepted Accounting Principles (GAAP). These non-GAAP financial measures are computed by excluding certain non-cash and/or other items from the related GAAP financial measure. The Company also includes a non-GAAP adjustment for the estimated income tax effect of reconciling items. A reconciliation of the Company's GAAP to non-GAAP results is included in Table 3 of this press release. 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 or changes in the fair value of the Company's investments in equity securities) or items that are not associated with normal, recurring operations (such as acquisition and integration costs). Management uses these 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. With respect to free cash flows, the Company believes that this non-GAAP measure provides a further measure of the Company's ability to generate cash flows from its operations. Additionally, such 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 these and other 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 the Company should be considered supplemental to, and not a substitute for, measures of financial performance prepared in accordance with GAAP. (b) The casirivimab and imdevimab antibody cocktail for COVID-19 is known as REGEN-COV in the United States and Ronapreve in other countries. Roche records net product sales of Ronapreve outside the United States. (c) The Company's 2024 financial guidance does not assume the completion of any business development transactions not completed as of the date of this press release. (d) Gross margin on net product sales represents gross profit expressed as a percentage of total net product sales recorded by the Company. Gross profit is calculated as net product sales less cost of goods sold. (e) Corresponding reimbursements from collaborators and others for manufacturing of commercial supplies is recorded within revenues.
