AstraZeneca Bristol Myers Squibb Merger Report Drags on FTSE 100
Reports of a potential merger between AstraZeneca (AZN) and Bristol Myers Squibb (BMY) caused a 5% drop in AstraZeneca's shares, wiping £17 billion off its market value. Both companies denied the reports, and analysts suggest antitrust scrutiny would be significant due to overlapping oncology businesses. The FTSE 100 traded flat, with oil prices also falling due to geopolitical developments.
