- Market Share Leadership: Eli Lilly commands a 60% share of the U.S. weight loss drug market, driven by strong performance of its tirzepatide products (Mounjaro and Zepbound), solidifying its leadership in the rapidly growing weight loss sector.
- Competitive Landscape: Viking Therapeutics is advancing its VK2735 candidate through clinical trials, with strong results suggesting it could enter phase 3 trials in Q3, indicating potential competition against Lilly and Novo Nordisk's offerings, intensifying market rivalry.
- Demand and Supply Dynamics: The demand for weight loss drugs remains high, at times exceeding supply, providing Viking with an opportunity to carve out market share if its candidate successfully completes trials and gains regulatory approval.
- Investment Opportunity: Despite Eli Lilly's stock dropping about 8% this year, its forward P/E ratio has decreased to 28x, indicating a favorable investment opportunity in this weight loss leader, especially with the potential regulatory approval of its oral weight loss drug on the horizon.
