Groupe Casino now operates as Plesio, a French retail group focused on convenience shops. Its French portfolio comprises Monoprix, Casino, Vival, Cdiscount, Franprix and Naturalia.

The group reports more than 24,000 employees and nearly 6,500 sales outlets. Monoprix is one of its owned retail businesses and remains central to its French convenience presence.
