Diageo Names Sir Dave Lewis as New CEO Starting January 2026

Diageo, the company behind popular drinks like Johnnie Walker, Smirnoff, and Guinness, has appointed Sir Dave Lewis as its new Chief Executive Officer. He will take over on January 1, 2026.

Sir Dave brings years of experience in running big consumer companies. He was CEO of Tesco from 2014 to 2020, where he successfully turned the business around. Before that, he spent almost 30 years at Unilever, leading marketing and growth efforts. 

He currently chairs Haleon, a major player in consumer health products, but will step down from that role at the end of 2025.

He also serves on the board of PepsiCo and is involved with The Royal Foundation and the UK branch of the World Wildlife Fund. He was knighted in 2021 for his work in business and the food industry.

Diageo’s Chairman, Sir John Manzoni, led the search for the new CEO. “We’re thrilled to have Dave join us,” he said. “After a thorough global search, the board agreed he’s the right leader to grow our iconic brands in today’s changing market.”

Sir Dave shared his excitement: “Diageo has an amazing collection of brands. Yes, there are challenges ahead, but also great opportunities. I look forward to working with the team to build value for shareholders.”

Until the end of 2025, Nik Jhangiani will continue as interim CEO before returning to his role as Chief Financial Officer. Deirdre Mahlan, who stepped in as interim CFO, will stay on to help with the transition.
