Management Comments

• Vlad Coric, M.D., Chairman and CEO: "We made significant progress over the past year in advancing our pipeline of innovative therapies, particularly with our revolutionary degrader platform, the central pillar of our long-term strategic focus in immunology and inflammation."
• Vlad Coric, M.D., Chairman and CEO: "Our degrader portfolio possesses the potential to address an array of well-validated targets with highly differentiated mechanisms of action, reinforcing our confidence in this platform as a meaningful driver of future value creation, and we have the unique opportunity to be the first to market with this innovative technology."
• Vlad Coric, M.D., Chairman and CEO: "Our selective Kv7 program is an extremely promising approach for treating focal epilepsy, which has the potential to address the significant unmet medical need for a novel efficacious antiseizure medicine that is easy-to-use, does not burden patients with central nervous system (CNS) side effects like dizziness and somnolence, and does not make their comorbidities worse."
• Vlad Coric, M.D., Chairman and CEO: "We were very excited to report preliminary data demonstrating strong signals of efficacy from our ongoing open label extension (OLE) trial of opakalim, including improvements in seizure frequency greater than or equal to 50% in the majority of participants treated with opakalim 75 mg once daily for at least six months in the OLE, coupled with an exceptional tolerability profile. We are on track to deliver pivotal topline data from this program this year."
• Vlad Coric, M.D., Chairman and CEO: "With our myostatin-activin pathway inhibitor, taldefgrobep alfa, we are now exploring the opportunity to address critical gaps in the treatment of obesity. Specifically, taldefgrobep is designed to directly target fat, build muscle and increase bone density while avoiding the intolerable adverse effects that occur with other myostatin-activin inhibitors. We look forward to reporting topline data with this exciting program this year."
• Matt Buten, CFO: "Though progress across our portfolio was demonstrable, we redoubled efforts to execute with a renewed emphasis on financial discipline. During the final quarter of 2025, we initiated strategic portfolio and cost-optimization measures, carefully prioritized investments, aligned spending with clear development milestones, and maintained a prudent approach to capital allocation."

Industry Context

StockSavvy.ai notes that Biohaven's focus on extracellular protein degradation (MoDE/TRAP) positions it at the forefront of a novel therapeutic modality in immunology, potentially offering highly selective treatments with fewer off-target effects compared to traditional immunosuppressants. The Kv7 activation for epilepsy addresses a significant unmet need for well-tolerated antiseizure medications, a common challenge in the neurology space. In obesity, taldefgrobep's muscle-sparing and bone-density-increasing mechanism differentiates it from GLP-1 agonists, which primarily focus on weight loss and can lead to muscle mass reduction, suggesting a complementary or alternative approach in a rapidly evolving market. The ADC portfolio also aligns with the growing trend of targeted cancer therapies.

Comparison to Industry Standards

• BHV-1300's potential for best-in-class IgG reductions (up to 87%) and complete suppression of TSH receptor-stimulating antibodies in Graves' disease could offer a significant advantage over existing therapies like anti-thyroid drugs or radioactive iodine, which have limitations in long-term efficacy or side effects.
• BHV-1400's rapid and deep lowering of Gd-IgA1 (>60% mean reduction) and early clinical responses in IgAN patients position it favorably against current IgAN treatments, which often focus on symptom management rather than directly targeting the disease-causing protein. For example, current treatments like SGLT2 inhibitors or corticosteroids offer broad immunosuppression or kidney protection, whereas BHV-1400 aims for a more targeted approach.
• Opakalim's 50% seizure frequency reduction in the majority of OLE participants with a low incidence of CNS adverse events represents a highly differentiated safety profile compared to many approved antiseizure medicines (ASMs) such as levetiracetam (Keppra) or lacosamide (Vimpat), which often carry significant CNS side effects like dizziness, somnolence, and cognitive impairment, impacting patient adherence and quality of life.
• Taldefgrobep's mechanism of reducing fat mass while increasing lean muscle mass and bone density contrasts with GLP-1 receptor agonists (e.g., Ozempic, Wegovy), which, while effective for weight loss, can lead to a substantial loss of lean muscle mass. This differentiated profile could make taldefgrobep a compelling option for patients seeking "high quality" weight loss.
• BHV-1510 (Trop2 ADC) showing confirmed objective response rates of 60% in NSCLC, 100% in endometrial cancer, and 50% in urothelial cancer, with a differentiated safety profile (low rates of hematological toxicities, diarrhea, no interstitial lung disease) compares favorably to other Trop2 ADCs like Trodelvy (sacituzumab govitecan), which has shown efficacy but also carries risks of neutropenia and diarrhea. The potential for subcutaneous administration is also a significant patient convenience advantage.

Stakeholder Impact

• Shareholders: Potential for increased value through successful clinical development and future commercialization of prioritized assets; dilution from recent share issuances; improved financial discipline may lead to more sustainable operations.
• Patients: Potential for novel, life-changing therapies for Graves' disease, IgA Nephropathy, epilepsy, obesity, and various cancers with differentiated safety and efficacy profiles.
• Employees: Restructuring and cost optimization efforts may impact non-priority program teams, but focus on core programs provides clarity and potential for long-term growth.
• Creditors: Strengthened cash position from capital raises improves short-term liquidity and ability to meet obligations.
