Coop Eesti Keskühistu has agreed to acquire Prisma Peremarket and its 13 stores in Estonia from Finland’s SOK. The agreement was announced on 7 April 2026 and is subject to approval by the Estonian Competition Authority. The move is designed to expand Coop’s store network, particularly in Tallinn, and to establish closer strategic cooperation between the two retail groups.
The transaction represents a significant step in Estonia’s grocery retail consolidation. Coop, already the country’s largest food retailer, is using the deal to strengthen its position in urban markets where its presence has been more limited. Prisma’s established store network provides immediate scale in key locations.
In practical terms, the acquisition covers 13 supermarkets across Tallinn, Harju County, Tartu, Narva and Rapla. The Prisma brand and Sokos Hotel Viru are not included in the agreement. Following completion, the stores will be operated by Coop’s regional consumer cooperatives rather than centrally, maintaining the group’s existing structure.
For the Estonian market, the impact is most visible in Tallinn. Coop’s market share in the capital is expected to rise to just over 15%, still below its national average but significantly stronger than before. In other regions, the effect on market share is expected to remain limited.
Beyond store ownership, the agreement sets the foundation for broader cooperation between Coop and SOK. The partnership is expected to expand product sourcing, particularly by increasing the availability of Scandinavian ассортимент in Estonia while supporting the potential export of Estonian goods into Nordic markets.
From a supplier perspective, the enlarged network creates wider distribution opportunities. Coop’s scale and logistics infrastructure could offer improved market access for both domestic producers and international FMCG brands. At the same time, closer ties with SOK may strengthen private label development and cross-border supply chains.
The deal also reflects a wider trend in Northern European retail, where cooperative groups are consolidating operations and forming partnerships to compete more effectively on pricing, ассортимент and supply efficiency. Estonia’s relatively small but competitive market has seen increasing pressure on retailers to scale up and optimise operations.
The transaction remains under review by the Estonian Competition Authority, with approval expected during 2026. Until then, Coop and Prisma will continue to operate separately. Once cleared, integration will focus on store operations, sourcing alignment and the development of joint supply initiatives between Estonia and Finland.

The transaction remains subject to regulatory approval, and both parties continue to operate independently until clearance is granted.
