O'Key Group S.A. (OKEY.ME) operates as a leading Russian food retailer, focusing on discount stores under the DA! brand; it offers a wide assortment of food products including dairy, meat, bakery, and delicatessen items, non-food goods such as household items, clothes, shoes, toys, and appliances, as well as private-label products through an extensive network across Russia, primarily in the Central Federal District, Northwest, Urals, and other regions. The company, founded in 2002 and headquartered in Luxembourg with operational base in Moscow, Russia, previously managed hypermarkets under the O'KEY brand, e-commerce platforms, real estate, import, and financing activities; it employs over 19,000 people and runs five distribution centers in Moscow and St. Petersburg. In a major strategic shift, O'Key Group completes the sale of its O'KEY hypermarket chain, including stores, online platform, trademarks, and logistics infrastructure, to the chain's management in November 2025, retaining the DA! discounter network of 224 stores alongside 77 hypermarkets at year-end 2024 for continued expansion; shareholders approve redomiciliation from Luxembourg to Russia as an international public joint-stock company in the Kaliningrad special administrative region in March 2025, enhancing operational alignment without disrupting retail activities.
