Why is Haleon stock plunging today?
Haleon's stock dropped 11.8% after lowering its 2026 revenue growth outlook to 2.5%, citing weak respiratory health sales and market challenges. Analysts cut price targets, and share buybacks failed to offset the decline. The FTSE 100's slight gain did not mitigate the company-specific drop.
