The company is owned by a Hong Kong listed company Wing On Company International Limited (SEHK: 289), incorporated in Bermuda. The holding company of the listed company itself is Wing On International Holdings Limited, which is owned by Karl Kwok Chi Leung (郭志樑)[1] and the Kwok family.

"Brothers James Gock Lock (Kwok Lok) (郭樂) and Philip Gock Chin (Kwok Chuen) (郭泉) started the Wing On fruit store in Australia in 1897. Wing On imported nuts, tea, rice, fireworks and ginger from China. The original "Wing On Building", located at 37 Ultimo Road in Haymarket, New South Wales, in Sydney's Chinatown, is now a hotel.[4]

In 1907, James, Philip and their other brother William Gock Son (Kwok Sun) returned to Hong Kong with accumulated savings and founded the Wing on Company, the second Chinese-owned department store in Hong Kong. They expanded to Shanghai in 1918."
