Novo Nordisk Stock Under Pressure Following Split Monday Announcements: STEP Young Pediatric Win Offset by Ziltivekimab HERMES + ATHENA HF Terminations; Barclays Cuts Price Target to DKK 300
Novo Nordisk (NYSE: NVO; Copenhagen: NOVO-B) shares closed at DKK 298.95 in Copenhagen on Monday September 7, 2026 (roughly 1.9% below Friday) after the company's simultaneous release of STEP Young Phase 3 pediatric semaglutide data (40.4% of children aged 6 to under 12 achieved BMI below the obesity threshold at week 68 versus 0% placebo) and confirmation that the HERMES and ATHENA Phase 3 ziltivekimab (anti-IL-6 monoclonal antibody) heart-failure trials had been terminated early after a data monitoring committee ruled the studies unlikely to succeed. Barclays' James Gordon cut the Novo Nordisk price target from DKK 310 to DKK 300 while maintaining an Equal Weight rating. Analyst commentary broadly framed the day as a scientific-engine-versus-diversification tension: the semaglutide franchise continues to add indication paths (pediatric obesity below 12 years is one of the last major label extensions available), while the non-GLP-1 diversification story tied to ziltivekimab now depends primarily on the post-acute heart-failure study that remains ongoing. Detailed STEP Young results will be presented at ObesityWeek 2026 in Washington DC November 14-17.
