AstraZeneca and Bristol Myers Squibb Held Early Stage Combination Talks With No Deal Confirmed
Reports confirmed by a person familiar with the matter indicate AstraZeneca and Bristol Myers Squibb held preliminary combination discussions, though no agreement, transaction structure, or offer price has been disclosed. A combined entity would carry a combined market capitalization of roughly $400 billion and would rank as the world's largest drugmaker by revenue, but no formal regulatory or company filings have confirmed a transaction is underway. AstraZeneca shares fell approximately 9% on August 3 following the reports, their steepest single-day decline since 2020.
