Group 1 - Viking Therapeutics' stock fell 42% on August 19, 2025, due to disappointing Phase 2 results for its oral obesity pill VK2735, which showed only up to 12.2% weight loss over three months, underperforming compared to competitors like Eli Lilly and Novo Nordisk [2] - 28% of patients discontinued VK2735 therapy due to side effects such as nausea and vomiting, indicating potential challenges in patient adherence [2] - Despite the setback with VK2735, Viking has a diversified pipeline with several promising candidates that may be undervalued by the market [3] Group 2 - Viking's current stock price of $24 is significantly below the analyst average price target of $89, suggesting a valuation disconnect that may not be justified given the company's diversified pipeline [3] - The Phase 3 trials for VK2735's subcutaneous formulation began in June 2025, and prior Phase 2 data indicated a viable injectable route with up to 13.1% placebo-adjusted weight loss [6] - Other pipeline assets include VK2809 for NASH/MASH, VK5211 for hip fracture recovery, VK0612 for type 2 diabetes, and VK0214 for X-linked adrenoleukodystrophy, contributing to further diversification [6] Group 3 - Key risks for Viking include potential clinical disappointments, substantial capital needs for Phase 3 trials, and intense competition in metabolic disorders [7] - For risk-tolerant long-term investors, the current valuation may over-penalize the company for the shortcomings of one program, presenting a speculative investment opportunity [7] - The conclusion suggests that if execution improves across other programs, the diversified pipeline could offer meaningful long-term upside [7]
