Business Highlights Key Pipeline ProgressRegeneron has approximately 40 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 The Company announced that the primary endpoint was met in the Phase 3 QUASAR trial investigating EYLEA HD for the treatment of patients with macular edema following RVO, including those with central, branch, and hemiretinal vein occlusions. In the trial, patients treated with EYLEA HD every 8 weeks (after initial monthly doses) experienced non-inferior vision gains compared to those treated with the approved monthly dosing regimen of EYLEA, the current standard of care. The Company plans to submit a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) in the first quarter of 2025.A regulatory application for a pre-filled syringe was submitted to the FDA, with an FDA decision expected by mid-2025. Dupixent (dupilumab) In November 2024, the European Commission (EC) approved Dupixent to treat eosinophilic esophagitis (EoE) in children aged 1 to 11 years, making Dupixent the first and only medicine indicated to treat these young patients.The FDA accepted for review the resubmission of an sBLA for Dupixent to treat adults and adolescents aged 12 years and older with chronic spontaneous urticaria (CSU) whose disease is not adequately controlled with H1 antihistamine treatment, with a target action date of April 18, 2025.An sBLA for Dupixent in bullous pemphigoid was submitted to the FDA.A Phase 3 study in lichen simplex chronicus was initiated. Libtayo (cemiplimab) The Company announced positive results from a Phase 3 trial of Libtayo, which demonstrated that adjuvant treatment with Libtayo was the first and only immunotherapy that led to a statistically significant and clinically meaningful improvement in the primary endpoint of disease-free survival (DFS) in patients with high-risk CSCC after surgery.A Phase 3 study of Libtayo administered intralesionally in patients with early-stage CSCC was initiated. Hematology Programs In January 2025, the Company resubmitted to the FDA the BLA for linvoseltamab, a bispecific antibody targeting BCMA and CD3, in relapsed/refractory (R/R) multiple myeloma following resolution of third-party manufacturing issues.In January 2025, the Company resubmitted to the FDA the BLA for odronextamab, a bispecific antibody targeting CD20 and CD3, in R/R follicular lymphoma.The Company presented new and updated data for odronextamab spanning several B-cell non-Hodgkin lymphoma (B-NHL) subtypes across earlier lines of treatment at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition.The Company announced positive Phase 2 results for two antibodies targeting distinct domains of Factor XI. REGN7508 (catalytic domain) is designed to maximize anticoagulant activity while minimizing bleeding risk, and REGN9933 (A2 domain) is designed to provide an additional option for patients with the highest bleeding risk who would otherwise not be candidates for currently available anticoagulants. Per the Phase 2 results, there was a robust antithrombotic effect for each antibody, and no clinically relevant bleeding was observed.The Company announced positive updated data from a Phase 3 study of pozelimab (C5 antibody), in combination with cemdisiran (siRNA therapy), against ravulizumab, a standard-of-care C5 inhibitor, in patients with paroxysmal nocturnal hemoglobinuria (PNH). The study showed that the combination treatment helped patients achieve and maintain greater disease control, compared to ravulizumab. These results were presented at the 66th ASH Annual Meeting and Exposition. Other Programs The EC approved Kevzara® (sarilumab) for the treatment of polymyalgia rheumatica (PMR) and polyarticular juvenile idiopathic arthritis (pJIA).A Phase 3 study for mibavademab, an agonist antibody to leptin receptor (LEPR), in generalized lipodystrophy was initiated.Enrollment was completed in a Phase 2 study in obesity for trevogrumab, an antibody to myostatin (GDF8), in combination with semaglutide with and without garetosmab, an antibody to Activin A.A Phase 2 study for itepekimab, an antibody to IL-33, in chronic rhinosinusitis without nasal polyposis (CRSsNP) was initiated.A Phase 2 study for REGN7544, an antagonist antibody to NPR1, in postural orthostatic tachycardia syndrome (POTS) was initiated.The Company shared initial data from the first patient in a Phase 1 study of linvoseltamab, in combination with Dupixent, in severe food allergy at the 43rd Annual J.P.

Net product sales of EYLEA HD and EYLEA in the fourth quarter and full year 2024 were adversely impacted by a lower net selling price compared to the same periods of 2023. In addition, fourth quarter 2024 total EYLEA HD and EYLEA net product sales were favorably impacted by approximately $85 million as a result of higher wholesaler inventory levels for EYLEA, partially offset by lower wholesaler inventory levels for EYLEA HD, at the end of the fourth quarter 2024 compared to the end of the third quarter 2024. Sanofi collaboration revenue increased in the fourth quarter and full year 2024, compared to the same periods of 2023, due to an increase in the Company's share of profits from the commercialization of antibodies, which were $1.043 billion and $886 million in the fourth quarter of 2024 and 2023, respectively, and $3.924 billion and $3.137 billion for full year 2024 and 2023, respectively. 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. Sanofi collaboration revenue in 2023 was positively impacted by the recognition of a $50 million sales-based milestone. Collaboration revenue for full year 2023 included $224 million in connection with the Company's share of global gross profits from sales of Ronapreve by Roche.

The GAAP ETR increased in the fourth quarter of 2024, compared to the same period in the prior year, due to a lower benefit from stock-based compensation. In the fourth quarter and full year 2024, the non-GAAP ETR was 9.9% and 9.6%, respectively, compared to 2.4% and 9.1% in the fourth quarter and full year 2023, respectively.

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 flow, 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, the non-GAAP measures presented are intended to 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 2025 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.
