Merger with Groupe Casino

After the Asian financial crisis of 1997, Big C Supercenter PCL formed a business alliance with France-based Groupe Casino, known for its Géant stores. Groupe Casino bought 530 million shares of a capital increase in 1999, making them the largest shareholder after the company's recapitalization. After securing the controlling stake in Big C, Groupe Casino sold Big C's garment business in order to concentrate only on retail activity to strengthen the efficiency of the operation.


Big C extended its business hours from 08:00 to midnight daily and launched the Big C website in 2000. Two years later, Big C launched a hard-discount supermarket chain, "Leader Price by Big C", an affiliate store similar to the Leader Price brand of Groupe Casino. In the same year, Big C launched its first credit card, "Big C Credit Card", and "Big C Hire-Purchase". Big C Foundation was also launched in 2002, with its main objectives including providing necessary assistance and support for children in terms of education, and offering opportunities for education to those suffering as a result of social abuses or the drug trade.
Big C developed and expanded the "Compact Store" store concept in 2005. Compact Stores each require an investment of between 300 and 400 million baht, and have an average retail space of 5,000-6,000 square metres, whereas Big C's standard stores have retail space of about 10,000 square metres and require an investment of between 600-700 million baht. In May 2005, the "Big C Shopper Card" was launched, which was a hire-purchase card.
In 2006, Leader Price by Big C was remodeled into "Mini Big C", a proximity store format offering 24-hour service. Big C launched yet another new brand store format in July 2010 called "Big C Junior", which is sized midway between a compact store and a supermarket.

Global branding

"Big C" was used for the first time outside Thailand at the end of 2003, with the rebranding of three Cora hypermarkets in Vietnam. The stores were owned by Vindemia, a Groupe Bourbon company in Réunion. Casino took control of Vindemia, and the Big C Supercenter banner is used for these stores.
In 2010, Big C announced in Thailand that it would open its first store in Laos, inside The New Taladsao Shopping Mall in Vientiane, in late 2012.

Carrefour acquisition

In November 2010, Big C won a bid to buy the 42 Carrefour branches in Thailand for €868 million. After the acquisition, Groupe Casino, whose Thai subsidiary is Big C Supercenter PCL, owned 111 hypermarkets versus Tesco's 87. However, if other retail formats are included, Tesco is larger with some 704 stores nationwide.
Big C and Carrefour branches in Thailand had their first co-promotion in January 2011, before Carrefour Thailand stores were rebranded as Big C. And in March 2011, Carrefour Suwintawong was the first Carrefour store to be rebranded as a Big C.
