The story
Sonae Distribuição started in 1985 by the merger of two large retailers, Modelo and Continente. Modelo was owned by the Sonae holding, while Continente was the Portuguese and Spanish operation of the French retailer Promodès, known by the ensign Continent elsewhere.
Thus, it was part-owned by its French competitor, Carrefour, who sold their stake to Sonae for €345 million on 16 November 2004.
In 2008, Carrefour sold its Portuguese retail ventures existing under the Carrefour ensign to Sonae. Continente used to have one branch in Dubai, which was later purchased by Carrefour. The Continente ensign disappeared from Spain after the 1999 Carrefour-Promodès merge.
