AstraZeneca and BMS explore $400B mega-merger, sparking pharma consolidation chatter
Reuters reports AstraZeneca and Bristol Myers Squibb held preliminary talks about a potential merger valued at about $400 billion, which would create one of the world’s largest pharma companies. The status of talks is unclear, and such a deal would face U.S. antitrust scrutiny under the Trump administration and could require divestitures. The companies’ oncology franchises are a focal point, with historical context from Bristol Myers’ Celgene deal cited in analysis.
