Thanks, Len. Earlier this month at the JPMorgan conference, we highlighted the breadth and depth of our pipeline, which is expected to generate clinical data over the next few years, spanning oncology, hematology, complement-mediated diseases, anticoagulation and obesity as well as in other areas. In 2026, we plan to build on our established leadership in ophthalmology as well as immunology and inflammation while advancing key late-stage programs. Starting with ophthalmology. EYLEA HD was recently approved by the FDA for monthly dosing and for the treatment of RVO, further strengthening its clinical profile. Data supporting these approvals will be presented at the upcoming Angiogenesis meeting, further highlighting the efficacy, safety and durability of EYLEA HD, along with dosing flexibility designed to support more personalized patient care. In terms of our ophthalmology pipeline, for our C5 program for geographic atrophy, we expect interim data from our Phase III study in the second half of 2026. We are currently evaluating our C5 siRNA cemdisiran as monotherapy and also with pozelimab, our potentially best-in-class C5 antibody with the goal of providing a systemic treatment that avoids the safety issues from repeated intravitreal injections associated with currently approved GA therapies. In case intravitreal delivery is required to adequately treat this disease, we've also begun clinical development of an intravitreal formulation of pozelimab to evaluate local C5 inhibition for appropriate patients. Beyond GA and ophthalmology, we have initiated a study of a novel intravitreally delivered T cell receptor blocking antibody for non-infectious uveitis, a disease generally driven by autoimmune T cells. This advance was made possible by our unique antibody capabilities as we are not aware of any other company that's been able to generate such an antibody. This year, we also plan to initiate clinical development for a long-acting antibody targeting a novel genetically validated target for glaucoma, along with a long-acting antibody that aims to treat thyroid eye disease and Graves' disease. Moving to immunology and inflammation. We are committed to strengthening our leadership by advancing several next-generation therapeutic approaches. As we first revealed at the JPMorgan Conference, in addition to exploring longer dosing intervals for DUPIXENT, we are progressing Veloci-derived fully human long-acting antibodies with enhanced binding properties that target the IL-4 receptor alpha, the same target as DUPIXENT, as well as antibodies targeting IL-13, IL-4 and a bispecific antibody targeting both IL-4 and IL-13. All of these approaches are designed to enable extended dosing. Our long-acting IL-13 antibody is expected to enter the clinic in the coming months, embarking on an expedited development plan in atopic dermatitis that we believe will enable us to remain competitive as other industry players that are pursuing related approaches. Our other long-acting antibodies are expected to enter the clinic by 2027, each with a custom development plan. At the same time, our Regeneron Genetics Center has utilized its large-scale genetics approaches to identify several exciting new immunology and inflammation targets. Similar to DUPIXENT, we believe these may represent future pipeline and product opportunities. The first of these antibodies is expected to enter clinical development in the first half of this year. After initially evaluating healthy volunteers, we plan to rapidly advance this candidate to establish proof of concept in several genetically linked diseases such as lupus, Sjogren's and primary biliary cholangitis. Turning now to allergen. Our initial cat and birch Phase III studies demonstrated that allergen-specific monoclonal antibody cocktails can meaningfully address ocular endpoints, adding to earlier data that showed significant reductions in nasal, respiratory and skin endpoints. These Phase III data from the cat and birch programs will be presented at the upcoming AAAAI conference. We anticipate initiating the confirmatory Phase III study for cat allergy in the first half of the year, while the confirmatory Phase III study for birch allergy is already underway. We are also advancing an innovative strategy with the goal of eliminating all IgE-mediated allergies. Our initial clinical effort is in patients suffering from severe food allergies, involving transient Lynozyfic treatment followed by long-term DUPIXENT maintenance. This approach demonstrated proof of principle with the first 4 treated patients all achieving over 90% sustained IgE reductions. These results validate our approach of first removing IgE-producing plasma cells and then preventing their return. Building on this, we are developing next-generation agents specifically targeting IgE-producing cells with the first expected to enter clinical development over the next year for potentially more rapid and broader allergy applications. On to oncology and fianlimab, our LAG-3 antibody in combination with LIBTAYO. Our pivotal study in first-line metastatic melanoma remains on track to read out in the first half of this year. Early clinical data from our first-in-human study across multiple advanced melanoma cohorts suggested a potentially differentiated and best-in-class profile. Also in the first half of this year, we're expecting an interim analysis for our study in adjuvant melanoma as well as Phase II data in advanced non-small cell lung cancer, a more speculative setting, in which clinical validation has not yet been established for LAG-3 and PD-1 combinations. Moving to Heme-Onc, Lynozyfic, our BCMAxCD3 bispecific, is establishing a new benchmark in multiple myeloma. In late-line disease and with the caveat of cross-trial comparisons, Lynozyfic has demonstrated nearly double the complete response rate compared to other BCMAxCD3 bispecifics at similar follow-up times with lower rates of cytokine release syndrome, shorter hospitalization requirements and more convenient dosing intervals. Building on its remarkable monotherapy activity across multiple lines of therapy, we are undertaking an ambitious development plan to simplify the existing myeloma treatment paradigm, which currently relies on highly complex, intense and burdensome triple and quad drug combinations by exploring Lynozyfic monotherapy as well as in simple combinations in early line settings. In our Phase II study in newly diagnosed multiple myeloma, all 9 evaluable patients treated with Lynozyfic monotherapy at the planned Phase III dose achieved MRD negativity, an endpoint the FDA recently endorsed as a registrational-enabling for this malignant disease. Even more compelling are the early signals in myeloma precursor and related settings. For example, in evaluable patients with high-risk smoldering myeloma, Lynozyfic once again achieved 100% MRD negative in all 12 evaluated patients, whereas the standard of care, daratumumab, achieved less than 10% complete response. Similarly, in second-line patients with light chain amyloidosis, Lynozyfic monotherapy normalized abnormal light chain levels in approximately 2 weeks, whereas in a separate study, a daratumumab containing quad combo regimen took approximately 5 months to approach these levels in first-line patients. Both of these promising results could herald marked advances to existing standard of care, which can involve complex and [indiscernible] multidrug combinations. With 4 pivotal studies underway and 4 more initiating by the middle of this year, we are rapidly advancing our Lynozyfic development program with the hopes of transforming the myeloma treatment paradigm and ultimately preventing progression to malignant disease. On to complement-mediated diseases. Our C5 program consists of customized approaches to treat different diseases, which require different levels of target inhibition to maximize efficacy for each condition. I previously summarized above our C5 efforts in geographic atrophy. In our pivotal study for generalized myasthenia gravis, we showed that cemdisiran alone achieved differentiated efficacy and convenience with every 3-month subcutaneous dosing, delivering a potentially best-in-class profile with a placebo-adjusted improvement in the Myasthenia Gravis Activities of Daily Living score of 2.3 [ points ] at 24 weeks, the primary endpoint of the study and the best result among C5 inhibitors to date based on cross-trial comparisons. We remain on track to submit our U.S. regulatory application in the first quarter with potential approval anticipated later this year or early next year. In paroxysmal nocturnal hemoglobinuria or PNH, where our Phase III lead-in data showed the combination of cemdisiran and pozelimab was necessary to achieve potentially best-in-class disease control with 96% of patients controlled in the pivotal trial lead-in cohort and with the ability to rapidly rescue patients previously treated with ravulizumab who had not been well controlled. These results once again have the potential to deliver a best-in-class profile with pivotal data expected late this year or early next year, positioning this combination of C5 complement inhibitors as a new standard of care for PNH. Moving to anticoagulation. Clot prevention remains a critical unmet need since less than half of eligible patients received anticoagulant therapy, primarily due to concerns about their bleeding risk. To address this, we are developing 2 complementary Factor XI antibodies, one optimized for maximal antithrombotic activity and the other designed to further reduce bleeding risk, enabling a tailored approach based on individual patients' benefit risk profile. Initial clinical data support this strategy, showing impressive efficacy and a favorable bleeding profile compared to current standards of care. Pivotal studies are already underway in prevention of postsurgical venous thromboembolism or VTE, with pivotal studies in cancer-associated VTE prevention, catheter-associated thrombosis, stroke prevention in patients with atrial fibrillation and peripheral artery disease, all expected to initiate this year. Moving to obesity. We continue to pursue a differentiated strategy that includes olatorepatide, our in-licensed GLP/GIP agonist entering pivotal monotherapy studies in 2026 as well as a co-formulation of olatorepatide with Praluent, our antibody to PCSK9. Since current GLP agonists do not meaningfully lower LDL cholesterol, this co-formulated combination is designed to treat the large population of people living with obesity who also suffer from hyperlipidemia with a single, convenient and similarly affordable once-weekly subcutaneous injection analogous to the currently approved GLPs. Moreover, imagine if someone had invented a new GLP that in addition to delivering profound weight loss could also lower bad cholesterol by 50% to 60%. It would create an important and differentiated opportunity for the many obese patients simultaneously suffering hyperlipidemia with elevated cardiovascular risk. Our clinical program for this novel combination that we believe can deliver the same dual benefits is expected to begin later this year. Before I turn the call over to Marion, I would like to quickly address a couple of additional developments in our pipeline. In rare diseases, our DB-OTO gene therapy continues to produce transformative outcomes with meaningful hearing gains in 11 of the 12 treated children born with profound genetic deafness. This program was selected as the first new molecular entity to receive the FDA Commissioner's National Priority Voucher designation, and we are awaiting a regulatory decision in the first half of this year. In fibrodysplasia ossificans progressiva or FOP, a debilitating disease in which the soft tissues of the body are progressively replaced with abnormal bone, our garetosmab program demonstrated a more than 99% reduction in abnormal bone formation at 56 weeks, an unprecedented result, and we are waiting on regulatory decisions in the U.S. and EU in the second half of this year. Our commitment and dedication to these types of rare diseases, particularly those that affect children, not only speak to the heart and soul of Regeneron, but have also proven to pave the way for broader opportunities in the future as we would hope would be the case here. In summary, our scientific and clinical momentum continues to accelerate across the R&D enterprise with multiple pivotal readouts, regulatory milestones and first-in-class programs advancing in 2026. I have never been more excited about the breadth, depth and potential impact of our pipeline. With that, let me turn it over to Marion.
