AstraZeneca reportedly in merger talks with BMS

3 August 2026

UK pharma major AstraZeneca (LSE: AZN) has been in talks in recent months to combine with US rival Bristol Myers Squibb (NSE: BMY), about a deal that would create one of the world’s biggest pharmaceutical groups, valued at nearly $400 billion, according to a report by the Financial Times.

AstraZeneca, the UK’s second most valuable listed company, has a market value of about £196 billion ($264 billion), while BMS is worth roughly $133 billion. A combination of the two would be among the biggest pharmaceutical deals of all time, and propel the combined entity to become the world’s fourth-largest drugmaker by market capitalisation.
