DIA and the Spanish branch of Carrefour also represent two of the largest groups in the sector, both with a market share close to 9 percent. Carrefour in particular is the second supermarket brand in terms of turnover and number of workers, with a workforce of approximately 34 thousand people as of 2019. Grupo Día, which has experienced financial turbulence in recent years, saw its sales value fall below 4 billion euros for the first time in 2019 and wrapped up the year with losses. All the same, the group did not succumb to bankruptcy thanks to the financial aid supplied by Banco Santander that year.
Interestingly, the German supermarket chain Lidl, whose Spanish spinoff was founded in 1994, has considerably expanded its market in Spain, with a sharp increase in sales value of around 1.5 billion euros since 2014. In contrast, the Spanish Eroski Group has shrunk, although it remains stable as one of the most present brands in the industry, with sales amounting to about 1.7 billion euros in 2019.
