Géant was opened its first hypermarket in 1970. In June 2013, Géant Casino had about 130 hypermarkets all over the world. The concept is, like most hypermarkets, to have all kinds of items available under one roof. A loyalty card system has been introduced by Géant, with a price discount on certain groceries. There are over two million Géant card-holders.
Fu-Com joined with Groupe Casino to bring the Géant hypermarket brand to the Middle-East where Géant opened its first store in Bahrain May 2001. A store was opened in Dubai in 2005 and one in Abu Dhabi in 2015 at Yas Mall.
