VYVGART\u00ae Hytrulo is a subcutaneous combination of efgartigimod alfa (VYVGART) and recombinant human hyaluronidase PH20 (rHuPH20), Halozyme\u2019s ENHANZE\u00ae drug delivery technology to facilitate subcutaneous injection delivery of biologics. VYVGART is approved for generalized myasthenia gravis (gMG) and immune thrombocytopenia (Japan only). VYVGART Hytrulo is approved for gMG and chronic inflammatory demyelinating polyneuropathy (CIDP). VYVGART Hytrulo may be marketed under different proprietary names in other regions.<\/p>\n<p align=\"justify\">\n        <b>About Empasiprubart<\/b><br \/>\n        <br \/>Empasiprubart (ARGX-117) is a novel humanized monoclonal antibody that binds C2 and blocks activation of both the classical and lectin pathways of the complement cascade. By blocking complement activity upstream of C3 and C5, empasiprubart has the potential to reduce tissue inflammation and cellular damage, representing a broad pipeline opportunity across multiple severe autoimmune indications. In addition to multifocal motor neuropathy, argenx is evaluating empasiprubart in delayed graft function following kidney transplant,\u00a0and chronic inflammatory demyelinating polyneuropathy (CIDP).<\/p>\n<p align=\"justify\">\n        <b>About Adimanebart<\/b><br \/>\n        <br \/>Adimanebart (ARGX-119) is a first-in-class humanized agonist monoclonal antibody (mAb) that specifically targets and activates muscle-specific tyrosine kinase (MuSK) to promote maturation and stabilization of the neuromuscular junction (NMJ). It is a mAb derived from llamas and discovered using the argenx SIMPLE Antibody\u2122 platform technology. Adimanebart is being developed for patients with neuromuscular disease, including congenital myasthenic syndromes (CMS), amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy (SMA). Adimanebart was developed through argenx\u2019s IIP program in collaboration with the world\u2019s leading key opinion leaders on MuSK and the NMJ, Professor Steven J. Burden from MGH, Professor Shohei Koide from NYU and Professor Jan Verschuuren and Associate Professor Maartje Huijbers from LUMC.<\/p>\n<p align=\"justify\">\n        <b>About Generalized Myasthenia Gravis (gMG)<\/b><br \/>\n        <br \/>Generalized myasthenia gravis (gMG) is a rare and chronic autoimmune disease where IgG autoantibodies disrupt communication between nerves and muscles, causing debilitating and potentially life-threatening muscle weakness. Approximately 85% of people with MG progress to gMG within 24 months, where muscles throughout the body may be affected. Patients with confirmed AChR antibodies account for approximately 85% of the total gMG population.\u00a0<\/p>\n<p align=\"justify\">\n        <b>About Ocular Myasthenia Gravis (oMG)<\/b><br \/>\n        <br \/>Ocular myasthenia gravis (oMG) is a rare and chronic autoimmune disease characterized by muscle weakness limited to the muscles controlling the eyes and eyelids. Symptoms commonly include ptosis (drooping eyelids), diplopia (double vision), and fluctuating visual disturbance that can impair daily activities. Approximately 80% of myasthenia gravis (MG) patients initially present with ocular symptoms, and up to 92% experience ocular involvement at some point during the course of disease. While many progress to generalized myasthenia gravis (gMG), in 15\u201325% of patients, weakness remains restricted to the ocular muscles. oMG is driven by pathogenic IgG autoantibodies that disrupt communication at the neuromuscular junction. Despite the functional and quality-of-life burden associated with persistent ocular symptoms, there are currently no approved targeted therapies specifically for oMG. Treatment approaches often rely on symptomatic therapies and generalized immunosuppression, underscoring the need for additional therapeutic options for this distinct MG population.<\/p>\n<p align=\"justify\">\n        <b>About Generalized Myasthenia Gravis (gMG) without detectable AChR-Ab<\/b><br \/>\n        <br \/>Generalized myasthenia gravis (gMG) is a rare, chronic, neuromuscular autoimmune disease caused by pathogenic IgGs targeting the neuromuscular junction (NMJ), resulting in impaired neuromuscular transmission and debilitating and potentially life-threatening muscle weakness and chronic fatigue. Approximately 80% of patients with gMG have detectable antibodies against the AChR in sera, and these patients are diagnosed as AChR-Ab seropositive gMG. Approximately 20% of patients with gMG do not have detectable serum antibodies directed against AChR. These patients may have detectable autoantibodies targeting other NMJ proteins, such as muscle-specific tyrosine kinase (MuSK) and low-density lipoprotein receptor-related protein 4 (LRP4), or others. Anti-MuSK antibodies are detected in approximately 1-10% of patients with gMG, while anti-LRP4 antibodies are detected in approximately 1-5% of patients with gMG. About 10% of patients do not have any detectable autoantibodies against AChR, MuSK or LRP4. These triple seronegative patients have historically been excluded from studies and have a higher disease burden and unmet medical need compared to patients with detectable autoantibodies. Currently, there are no approved treatments available for patients with anti-LRP4 antibodies or for triple seronegative patients.<\/p>\n<p align=\"justify\">\n        <b>About Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP)<\/b><br \/>\n        <br \/>Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a rare and serious autoimmune disease of the peripheral nervous system. CIDP is a heterogenous disease involving different yet overlapping pathways and a varied disease course. There is increasing evidence that IgG antibodies and the complement system play a key role in the damage to the peripheral nerves. People with CIDP experience fatigue, muscle weakness and a loss of feeling in their arms and legs that can worsen over time or may come and go. These symptoms can significantly impair a person&#8217;s ability to function in their daily lives. Without treatment, one-third of people living with CIDP will need a wheelchair.<\/p>\n<p align=\"justify\">\n        <b>About Congenital Myasthenic Syndromes (CMS)<\/b><br \/>\n        <br \/>Congenital Myasthenic Syndromes (CMS) are an ultra-rare and heterogenous group of congenital neuromuscular disorders caused by genetic defects that are essential for the integrity of the neuromuscular junction. Early age of onset and fatigable muscle weakness are considered clinical hallmarks of CMS. Muscle weakness can be debilitating and life-threatening causing difficulties in speaking or swallowing, impaired or absent mobility, proximal arm and leg weakness, and respiratory insufficiency. DOK7 variations are one of the more frequent and severe causes of CMS, accounting for approximately 24% of CMS cases. There are no approved treatments. The prevalence of CMS is estimated to be 5 per 1M (DOK7-CMS estimated to be 1.2 per 1M).<\/p>\n<p align=\"justify\">\n        <b>About argenx<\/b><br \/>\n        <br \/>argenx is a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases. Partnering with leading academic researchers through its Immunology Innovation Program (IIP), argenx aims to translate immunology breakthroughs into a world-class portfolio of novel antibody-based medicines. argenx developed and is commercializing the first approved neonatal Fc receptor (FcRn) blocker and is evaluating its broad potential in multiple serious autoimmune diseases while advancing several earlier stage experimental medicines within its therapeutic franchises.

that are, or may be deemed to be, \u201cforward-looking statements.\u201d These forward-looking statements can be identified by the use of forward-looking terminology, including the terms \u201cadvance,\u201d \u201caim,\u201d \u201cbuild,\u201d \u201ccommit,\u201d \u201ccontinue,\u201d \u201cpotential,\u201d and \u201cwill,\u201d and include statements argenx makes concerning its plan to present certain new data at 2026 AAN Annual Meeting (including data for VYVGART and pipeline candidates empasiprubart and adimanebart) that continue to transform patient outcomes in myasthenia gravis (MG) and chronic inflammatory demyelinating polyneuropathy (CIDP) and build upon strength of pipeline; VYVGART\u2019s potential as the first targeted treatment for patients living with ocular MG; VYVGART\u2019s expanding treatment approach in CIDP; its advancement of its pipeline across two new mechanisms of action with an aim to deliver precision therapies for several neurological diseases with high unmet need; its plan to present myasthenia gravis (MG) data supporting its pursuit of the broadest label for MG patients, including: (1) data from the Phase 3 ADAPT OCULUS study, demonstrating the therapeutic potential of VYVGART in adults with oMG and the potential expansion of targeted\u00a0treatment options\u00a0for these patients,\u00a0marking\u00a0an important step\u00a0forward to expand\u00a0targeted\u00a0treatment options\u00a0for these patients; (2) data from Phase 3 ADAPT SERON and ADAPT Jr studies, supporting the use of VYVGART across broader patient populations, including patients with generalized myasthenia gravis (gMG) who do not have detectable anti-acetylcholine receptor antibodies (AChR-Ab) across three subtypes \u2013 MuSK+, LRP4+, and triple seronegative gMG, as well as in adolescents with gMG; and (3) additional MG presentations further characterizing the long-term safety and efficacy of VYVGART across both trial and real-world settings, as well as sustained clinical benefit across dosing patterns;\u00a0its plan to highlight results from an ADHERE post hoc analysis in treatment-na\u00efve patients with chronic inflammatory demyelinating polyneuropathy (CIDP) that underscore VYVGART Hytrulo&#8217;s impact in this underserved population and support its use earlier in the treatment paradigm; its intent to use real-world insights to further illustrate physician approaches to transitioning patients from IVIg to VYVGART Hytrulo to support positive patient outcomes; its plan to present featured research which includes ADHERE neurofilament light chain (NfL) data from the most comprehensive dataset to date, advancing CIDP innovation by exploring this potential biomarker of disease; its plan to share additional results from the ARGX-119 Phase 1b trial evaluating adimanebart in patients with DOK7 congenital myasthenic syndromes (CMS), providing proof-of-concept support based on a favorable safety profile and consistent functional improvements across multiple efficacy measures; argenx\u2019s relentless efforts to deliver a targeted treatment option to as many patients living with MG as possible; its commitment to improve the lives of people suffering from severe autoimmune diseases; its aim to translate immunology breakthroughs into a world-class portfolio of novel antibody-based medicines; its commercialization of the first approved neonatal Fc receptor (FcRn) blocker and evaluation of its broad potential in multiple serious autoimmune diseases; and its advancement of several earlier stage experimental medicines within its therapeutic franchises. By their nature, forward-looking statements involve risks and uncertainties and readers are cautioned that any such forward-looking statements are not guarantees of future performance. argenx\u2019s actual results may differ materially from those predicted by the forward-looking statements as a result of various important factors, including but not limited to, the results of argenx\u2019s clinical trials; expectations regarding the inherent uncertainties associated with the development of novel drug therapies; preclinical and clinical trial and product development activities and regulatory approval requirements; the acceptance of its products and product candidates by its patients as safe, effective and cost-effective; the impact of governmental laws and regulations, including tariffs, export controls, sanctions and other regulations on its business; its reliance on third-party suppliers, service providers and manufacturers; inflation and deflation and the corresponding fluctuations in interest rates; and regional instability and conflicts. A further list and description of these risks, uncertainties and other risks can be found in argenx\u2019s U.S. Securities and Exchange Commission (SEC) filings and reports, including in argenx\u2019s most recent annual report on Form 20-F filed with the SEC as well as subsequent filings and reports filed by argenx with the SEC.
