Who Is the Owner of Diageo?

Diageo PLC is a publicly listed company with no single dominant individual owner. It trades under the ticker DGE on the London Stock Exchange and as DEO on the NYSE (as American Depositary Receipts).

The company is governed by a Board of Directors, with Debra Crew serving as CEO since June 2023, becoming one of the few women to lead a FTSE 100 company in the consumer goods sector.

Corporate History and Formation

Diageo was formed in 1997 through the merger of Guinness PLC and Grand Metropolitan PLC — two major UK conglomerates with deep roots in food, beverages, and spirits. The Guinness name comes with over 260 years of brewing history in Dublin, Ireland. Grand Metropolitan brought a portfolio of spirits brands. The merger created a global spirits powerhouse with revenues and brand recognition spanning 180 countries.

Brand Empire and Revenue

Diageo’s brand portfolio is unmatched in the spirits world. Johnnie Walker is the world’s best-selling Scotch whisky; Smirnoff is the world’s best-selling vodka; Baileys dominates the cream liqueur category; and Guinness is an icon in stout. The company reported revenues of approximately £17.1 billion in FY2023, with operating profits of around £4.5 billion. Its strength lies in premiumization — pushing consumers toward higher-margin, higher-priced products.
