The transaction makes Erste Group the main shareholder with control of Poland's third-largest bank by assets.

The acquisition is expected to deliver a significant improvement in Erste Group's profitability. For 2026, the return on tangible equity is projected at approximately 19%, while earnings per share are anticipated to increase by more than 20%. This enhanced profitability will strengthen Erste Group's ability to deploy capital in a way that maximises shareholder value.

Erste Group and Santander Group are entering into a strategic alliance to better serve corporate and institutional clients across borders. Santander provides access to its international network and global product platforms, while Erste contributes its expertise in CEE. Corporate and institutional clients will benefit through a broader range of services in corporate, investment and correspondent banking, markets, cash management, export finance, as well as trade and working capital solutions.
