The bank's model focuses on three pillars: retail banking for individuals, corporate and investment banking, and treasury operations. Retail segment, which accounts for about 60% of revenue, includes deposits, consumer loans, and mortgages. According to the 2025 annual report published March 15, 2026, client assets under management reached PLN 250 billion as of December 31, 2025.
