Before Diageo’s Capital Markets Day, here is what every leadership change, asset disposal, and cost cut under Dave Lewis actually tells you

On 6 August 2026 – tomorrow – Diageo will publish its full-year FY2026 results and hold a Capital Markets Day at which CEO Sir Dave Lewis will present a complete transformation strategy for the business. It is the most anticipated single event in the drinks industry this year. And in the seven months since Lewis joined as CEO on 1 January 2026, the shape of that strategy has been visible not in statements or presentations but in the sequence of decisions he has already made: which people he has replaced, who he has brought in to replace them, where he has cut costs, what he has sold, and which markets he has chosen to address first.

This piece maps what Lewis has actually done since January, reads the specific logic behind each decision, and draws the commercial implications for every drinks producer that competes with Diageo, sells alongside its brands, or works in categories where Diageo’s choices set the commercial reference point for the rest of the market.

The starting point: what Lewis inherited

Lewis succeeded Debra Crew, who departed by mutual agreement in July 2025. Nik Jhangiani, Diageo’s CFO, served as interim CEO before Lewis formally took office on 1 January 2026. The business Lewis inherited had been in declining organic sales for six consecutive reporting periods. In H1 FY2026, Diageo reported organic net sales of –2.8%. North America – the largest market, accounting for 36% of group net sales – declined 6.8% organic in H1 FY2026 and 9.4% in Q3. Asia Pacific declined 9.4% across the nine months to March 2026. The share price had fallen approximately 30% over the prior twelve months. In February 2026, at the H1 results, Lewis cut the dividend to redirect capital toward investment, and confirmed a $625 million cost reduction mandate was underway. He described North America as a market where “there is much to do” and acknowledged the company was “significantly underrepresented” at the lower end of the market.

Lewis came to Diageo from Haleon, where he had been chairman since 2022. Before that, he served as Group CEO of Tesco from 2014 to 2020 – the restructuring of Tesco during a period of financial crisis earned him the nickname “Drastic Dave,” which he reportedly dislikes. Before Tesco, he spent 28 years at Unilever in a range of executive committee roles. His appointment to a luxury-adjacent consumer goods company facing a multi-year commercial decline was explicitly framed by Diageo’s board as a turnaround hire – the same logic that had seen Tesco go from profit scandal to operational recovery under his tenure.
