Thank you, Ryan, and welcome to everyone joining our call today. We're pleased to report another quarter of strong performance driven by outstanding commercial execution and a large and diverse pipeline that is continuing to deliver on its promise. Total revenue grew 36% and non-GAAP earnings per share grew 70% compared to the third quarter of 2025. This marks our third consecutive quarter of double-digit growth on both the top and bottom lines. Our commercial teams continue to execute at a very high level. Dupixin, Hylia HD, and Liptio each set new all-time highs for quarterly net sales for the second quarter in a row. Dupixin global net sales in the third quarter, as reported by Sanofi, reached a record $6.5 billion, up 35% year-over-year at constant currency, which is truly remarkable for a medicine approaching 10 years on the market. In the U.S., where Dupixent is the leading biologic in eight of its nine FDA-approved indications, quarterly net sales grew 40% and exceeded $5 billion for the first time, primarily driven by robust demand across all indications, as well as gross-to-net favorability, as disclosed by Sanofi. ILEA-HD quarterly net sales in the U.S. reached a new all-time high of approximately 700 million, up 62% from a year ago, and now represent nearly two-thirds of our U.S. retinal franchise. Physician unit demand grew 20% sequentially, reflecting the value retinal specialists and their patients see in extended dosing intervals, as well as last year's label enhancements, which added the retinal vein occlusion indication and greater dosing flexibility. We remain optimistic for approval of the pre-filled syringe before the end of the year, and we expect it to drive even further adoption if approved. Liptio is making important differences for patients with skin and lung cancers, and it continues to build clinical and commercial momentum. In the U.S., it is the leading immunotherapy in non-melanoma skin cancers and the second most prescribed immunotherapy in non-small cell lung cancer. Global net sales reached a record $550 million, up 51% in constant currency, and U.S. net sales grew 81% to nearly $400 million. Last week at ESMO, we presented longer-term data from our Phase III C post-trial, showing an increasing overall survival benefit with adjuvant Libtio in high-risk cutaneous squamous cell carcinoma, where it is the first and only approved immunotherapy. Liptio is now on an annual run rate of approximately 2.2 billion and remains the foundation for our broader oncology strategy. Beyond our strong commercial execution, our pipeline is poised to deliver several potential blockbuster opportunities over the next several years. Let me highlight new advances in four of our pipeline programs while George will discuss in more detail along with other late-stage clinical programs, including Factor XI, Linazific, and Otorepetide. In neuromuscular disease, we expect an FDA decision in November for Simdisiran and generalized myasthenia gravis. If approved, Simdisiran would be the first siRNA therapy for generalized myasthenia gravis and the only treatment that can offer quarterly subcutaneous dosing. Early in my career as a neurologist, I cared for many patients with this difficult-to-treat condition, so it is particularly gratifying to see us bring forward a potential new treatment option for them. In metabolic disease, MASH affects millions of people and treatment options are limited. Our Side B program is a great example of our genetics-driven scientific process. Regeneron Genetic Center discovered that people with naturally occurring loss of function variants of the Side B gene have a markedly lower risk of fatty liver disease and cirrhosis, which led us to develop a first-in-class sRNA that targets Side B. We are encouraged by the initial clinical data, which suggests best-in-class, best-in-disease potential, and we are rapidly advancing this program into registration-enabling studies. I'd also like to highlight our program for postural orthostatic tachycardia syndrome, or POTS. This is an increasingly recognized debilitating condition that affects many young people, often disrupting school, work, and daily life with very few effective treatment options and no FDA-approved medicines. Recent estimates suggest that between 500,000 and several million people in the U.S. alone suffer from PAS. We believe the initial clinical data that George will highlight supports our antibody's potential to become the first FDA-approved treatment for this disease, and we plan to initiate a potentially pivotal study next year pending regulatory feedback. In oncology, we recently shared encouraging data for the Ubimanumab, our MUC16 by CD3 bispecific antibody, an advanced low-grade serous ovarian carcinoma. This is a rare and difficult to treat form of ovarian cancer that often affects younger women who urgently need better treatment options. We saw durable responses in heavily pretreated patients at rates well above those historically seen with available therapies. We are already enrolling a dedicated, potentially registrational cohort and plan to start a confirmatory phase to be studied next year. Each of these programs is supported by compelling clinical data, human genetic validation, or both. It is no accident that they span four distinct therapeutic areas and that each has first-in-class or best-in-disease potential. That reflects our disease-agnostic enterprise approach to R&D. Rather than confining ourselves to a few therapeutic areas, we apply our core technologies wherever the science leads us. These technology platforms, including our Velocimune antibody and bispecific engines, Regeneron Genetic Center, and siRNA and gene editing technologies that allow us to translate genetic discoveries like Side B into potential medicines. Today, that approach supports approximately 50 clinical programs spanning immunology, oncology, ophthalmology, hematology, cardiovascular and metabolic diseases, neurology, and Rare Diseases. Our commercial organization has been built the same way. Our teams already call on ophthalmologists, dermatologists, pulmonologists, allergists, gastroenterologists, ENT specialists, oncologists, cardiologists, and hematologists. And if Semdiseran is approved, we will begin to call on neurologists as well. That means many of our pipeline medicines, including several of the programs I just mentioned, can launch into specialties where we already have deep relationships and expertise and can leverage our existing infrastructure and capabilities. Briefly on business development. Historically, we have been a net outlicenser of innovation, with the most recent example being the expansion of our alliance with Sanofi. We are contributing to the alliance for next-generation long-acting antibodies, all invented at Regeneron, that target the same pathways that made Dupixent so successful. Regeneron will lead research and development, and Sanofi will lead global commercialization, now with greater transparency and increased participation by Regeneron. If approved, these medicines can also benefit from Dupixent's commercial leadership and the strong market access position it has established, an advantage neither company could capture on its own. At the same time, our financial strength positions us to bring differentiated external innovation into Regeneron. We've done this effectively to date, primarily through early-stage research collaborations, including those that built our emerging genetic medicines pipeline across sRNA therapeutics, gene therapy, and gene editing. We continue to evaluate a wide range of opportunities, from early clinical programs and platforms to commercial-stage products with a sharp focus on valuation and strategic fit. In closing, this was an exceptional quarter by every measure. Our three core growth brands are performing at record levels and our expanded alliance with Sanofi positions us to lead the next era of type two inflammation medicines. Our pipeline is poised to deliver additional potential blockbusters across a broad range of diseases and our commercial organization is built to bring them to patients. Our future is bright and we remain focused on translating our science into new medicines that can make a meaningful difference for patients and create long-term value for shareholders. With that, let me turn the call over to George.
