Walmsley saw the company through the pandemic and has overseen the rollout of a vaccine for RSV as well as the separation of GSK’s consumer business into a separate company called Haleon Plc. Still, investors have been disappointed by sputtering vaccine sales and concerns about GSK’s pipeline of new drugs.

Under Walmsley’s watch the shares have fallen about 11% as investors remain concerned about the state of the company’s pipeline, with few drugs under development seen as potential blockbusters.
