Luke Miels, Chief Executive Officer, GSK:

“GSK has delivered another quarter of strong core results performance, with our key growth drivers performing well. We remain focused on operational delivery, execution, and accelerating R&D. 

To that end, we have identified late-stage pipeline accelerations - across 18 indications – for 7 key assets in Oncology, Respiratory, Hepatology and Vaccines. Based on clinical data, and their opportunities to improve upon current standards-of-care, we see strong reasons for all these assets to bring meaningful benefits and protection to patients. We have also decided to establish a new flagship R&D Centre on the UK’s Cambridge Biomedical Campus – an investment that will further integrate GSK into one of the world’s leading ecosystems for life-sciences. 

To fund investment in the late-stage portfolio and R&D, we are starting a 3-year cost savings programme to simplify the organisation and to reallocate capital and resources. Savings will primarily be reinvested, with some used to improve margins and profitability in the dolutegravir patent expiry period (2028-2030). 

We believe these plans, together with continued disciplined capital allocation, will drive strong operational performance and shareholder returns over the next five years, delivering our 2031 sales outlook and accelerated long-term growth.”
