Coop Eesti to take over 13 Prisma stores from SOK

Finnish retail group SOK is selling the 13 Prisma Peremarket stores it operates in Estonia to Coop Eesti Keskühistu; about 700 employees are to move to Coop and the stores become Coop stores, while the Prisma brand is not part of the deal. Completion needs approval from the Estonian competition authority and is expected in 2026; the parties agreed not to disclose the terms (ERR, 7 Apr 2026). Update (7 Sep 2026): Coop Estonia has completed the acquisition of the 13 stores after the competition authority approved it in May; the conversion to the Coop brand runs in phases until November, around 700 employees transfer and the national market share rises from about 23% to 28% (Eurocoop, 7 Sep 2026).
