Novo Nordisk A/SFaces fierce competition from Eli Lilly's tirzepatide and newly approved oral Foundayo, plus pricing pressure.
Novo Nordisk and Viking Therapeutics offer contrasting ways to invest in the booming obesity drug market. Novo Nordisk remains the global GLP-1 leader with a 54.6% volume market share, driven by blockbusters Ozempic, Rybelsus, and Wegovy, and is expanding labels for cardiovascular and kidney disease while advancing next-generation candidates like CagriSema and amycretin. However, it faces 2026 sales and earnings declines, pricing pressure, and fierce competition from Eli Lilly's tirzepatide and newly approved oral Foundayo. Viking Therapeutics is a clinical-stage biotech with no approved products, but its lead candidate VK2735, a dual GLP-1/GIP agonist, has shown promise in phase III studies with data expected in 2027, and it recently advanced a second obesity drug, VK3019, into phase I. Year to date, NVO shares have lost 5.5% while VKTX gained 8.2%, and VKTX trades at a higher price-to-book ratio of 8.8 versus NVO's 6.75. Despite near-term headwinds, Novo Nordisk's established portfolio, label expansions, and commercial scale make it the better pick for a balanced risk-reward profile, while Viking offers higher long-term upside tied to clinical success.
