GSK shares dive as weaker sales and mounting costs unnerve investors
GSK shares fell 5.5% despite better-than-expected earnings, due to weaker vaccine sales, restructuring costs, and a cautious outlook. The company reported a 19% decline in pre-tax profit to £1.9bn and £318m in restructuring charges. Sales rose 5% to £8.9bn, driven by HIV, cancer, and lupus drugs, but vaccine sales dipped 2%. GSK aims to generate £40bn in annual revenue by 2031 and is implementing a cost-saving plan to save £1.9bn annually.
