The announcement by ShopRite came months after another South African brand, Mr. Price, exited the market.
International supermarkets (excluding Nigeria) contributed 11.6% to group sales and reported 1.4% decline in sales from 2018. South African operations have contributed 78% of overall sales and saw a 8.7% rise for the year.
The company said it has been approached by potential investors willing to take over its Nigerian operations. It said it considering an outright sale of its operation or selling a majority stake in its Nigerian subsidiary.
ShopRite said in a statement on Monday.
