Casino Group or Casino Guichard-Perrachon is a French mass-market retail group. It was founded on 2 August 1898 by Geoffroy Guichard under the corporate name Guichard-Perrachon & Co. Casino Group is the source of many innovations, such as the first distributor's brand in 1901, the first self-service store in 1948, or even the display of a sell-by date on consumer products in 1959. Casino Group operates across all food and non-food formats: supermarkets, convenience stores, discount stores, and wholesale stores. Casino Group owns brands such as Monoprix, Franprix, Cdiscount, Vival, and Casino. Internationally, through its franchise subsidiary ExtenC, it also operates the Géant and Leader Price brands. As of 2017 Casino Group, managed by Jean-Charles Naouri, was quoted on the Paris Stock Exchange and had total revenue of €37.8 billion. As of November 2021, the group has a market capitalization of approximately €2.35 billion. Between June 2023 and October 2024, in the grip of a financial crisis linked to its debt, the group closed or sold all of its Casino supermarkets and Géant hypermarkets in France to competitors.
