London, Sept. 29, 2025 GlaxoSmithKline (GSK) has announced a major leadership shake-up as its long-serving Chief Executive Officer, Emma Walmsley, prepares to step down at the end of the year.
She will be succeeded by Luke Miels, the company’s Chief Commercial Officer, who is set to take over on January 1, 2026.
Walmsley, who became GSK’s first female CEO in 2017, is credited with steering the British pharmaceutical giant through a transformative period.
Her tenure saw the spin-off of GSK’s consumer healthcare division into Haleon, a sharpened focus on vaccines and biopharma, and a series of acquisitions aimed at strengthening the company’s drug pipeline.
In a statement, the GSK board praised Walmsley’s contributions and emphasized the need for “fresh leadership to define the next phase of growth.” Walmsley will remain with the company during a transition period, advising on strategy and ongoing global initiatives.
The announcement triggered a 2–3% rise in GSK shares on the London Stock Exchange, signaling investor confidence in the company’s succession plan. Analysts noted that Miels, who has led commercial operations since 2017, offers continuity while also bringing a sharper focus on revenue growth.
However, GSK faces significant challenges ahead. Patent expirations in its HIV portfolio, pressure to accelerate its research pipeline, and intensifying global competition mean the incoming CEO will inherit both opportunities and risks.
Miels, a seasoned pharma executive, previously worked with AstraZeneca and Roche before joining GSK. His new role comes with a base salary of £1.38 million, plus performance-related bonuses and long-term incentive opportunities.
Walmsley’s eight years as CEO leave a lasting mark on GSK’s history. Beyond corporate restructuring, she was a prominent advocate for diversity in leadership and invested heavily in next-generation vaccines and infectious disease research.
As one of only a handful of women to lead a major pharmaceutical multinational, her departure will be closely watched across the industry.
Investors and industry observers now look to Miels to balance stability with innovation. With 2026 described by the board as a “pivotal year” for the company, all eyes will be on how GSK navigates upcoming regulatory reviews, product launches, and possible acquisitions under its new chief.
