Weight-loss drug boom creates stark divide between biotech winners and wipeouts

Ascendis Pharma has regained exclusive rights to TransCon technology-based products in metabolic and cardiovascular diseases after ending its collaboration with Novo Nordisk. The company plans to advance its own programs in obesity and type 2 diabetes using its TransCon platform, with management highlighting once-monthly TransCon Semaglutide as a planned program within its expanded metabolic disease pipeline. Control of once-monthly TransCon Semaglutide and other metabolic projects shifts Ascendis from a partner model with Novo Nordisk to running these programs itself, concentrating both the potential upside and the development and commercialization costs inside one balance sheet. The regained rights and the once-monthly TransCon Semaglutide plans are only one part of the Ascendis story, and the company's existing rare endocrine portfolio still centers on YORVIPATH, SKYTROFA, and TransCon CNP or YUVIWEL. Key proof points now sit in the clinic and on the cash line, including formal trial initiation for once-monthly TransCon Semaglutide in obesity and type 2 diabetes, plus any updated R&D and share repurchase commentary at events such as the September 15, 2026 Morgan Stanley conference.

Amgen's updated analyst model lifted its fair value price target to US$388.03 from a prior US$371.93, with the revenue growth assumption rising to 3.50% from 2.93%, the net profit margin assumption moving to 25.15% from 24.84%, the future P/E multiple changing to 25.1x from 24.6x, and the discount rate shifting to 7.96% from 7.70%. The revision reflects a split analyst view, with UBS, Argus, TD Cowen, Scotiabank and Oppenheimer raising their Amgen price targets into a US$420 to US$460 range on the strength of a strong product portfolio, Q2 beats and higher guidance. Wells Fargo and Piper Sandler lifted their targets to US$435, citing external survey work and prescription data they believe support higher long term sales potential for cholesterol and cardiovascular products such as Repatha and Lipfendra. On the bearish side, HSBC downgraded Amgen to Hold and cut its target to US$425 from US$445, saying the stock price now more closely matches its assessment of fair value with limited near term upside, while BMO Capital shifted to a neutral Market Perform stance even with a higher US$450 target, citing ongoing loss of exclusivity headwinds and a need for more clarity on the competitive profile and sales potential of MariTide.

Novo Nordisk CEO Mike Doustdar is resetting the drugmaker's culture and competitive focus under a new "Novo Way" emphasizing customer focus, competitiveness, clarity and care, as the company rebrands to the day-to-day name "Novo" after losing ground to Eli Lilly in obesity drugs. Novo pioneered the modern obesity-drug market with Wegovy in the U.S. in 2021, but Eli Lilly has since gained ground with Zepbound and more aggressive consumer-focused commercialization. Novo has moved into oral obesity treatment with its Wegovy pill, and expects oral drugs to account for more than one-third of GLP-1 obesity-treatment use by 2030; analysts expect the U.S. obesity-treatment market to exceed $100 billion annually by 2030. Novo's Wegovy pill had captured roughly 90% of the U.S. oral-obesity market as of August, although Lilly subsequently said its Foundayo treatment had already captured more than 30% of new U.S. oral-treatment patients. Doustdar's message is that Novo must operate differently to defend and expand its position, and the company's September 21 capital-markets day should show investors how the "Novo Way" will translate into stronger competitive performance.
