Could Bristol-Myers Squibb (BMY) Outperform Novartis (NVS) as CAR-T Safety Concerns Shake the Sector?
Novartis (NVS) paused eight CAR-T trials after patient deaths, prompting Bristol-Myers Squibb (BMY) to halt its own trials. BMY reported Q2 revenue of $13.0B (+6% YoY) and raised 2026 guidance to $49.0-50.0B. NVS reported Q2 sales of $14.4B (+3%) but reaffirmed guidance. BMY's growth portfolio outperformed, while NVS faces generic competition.
