Atmósfera Sport, the Spanish buying group, has expanded its 2,000-m² head office near Valencia by an additional 1,000 square meters. The reasons given for extension are a growing number of retail members and plans for a stronger verticalization process for the group's operations. According to CMD Sport, the group's revenues have been rising steadily since 2010, and they grew by 8 percent to €22.9 million in 2015 as compared to the previous year. The number of affiliated retail stores rose by 6 percent to 274, with an average selling surface of 152 square meters. Retail sales increased by 4.6 percent to €45.9 million before VAT.
