Permanent TSB Group Holdings plc (PTSB) is a prominent Irish financial institution focused on retail and small-to-medium enterprise (SME) banking. The bank's core business model revolves around taking customer deposits and providing lending products, primarily residential mortgages, which account for the vast majority of its loan book. PTSB also offers personal loans, credit cards, overdrafts, and day-to-day banking services such as current accounts and payment solutions. In recent years, the bank has expanded its business banking and asset finance operations, significantly bolstered by the acquisition of a large portion of Ulster Bank's retail and SME business in the Republic of Ireland.
Revenue is predominantly generated through net interest income, which accounted for approximately €590 million of its €655 million total operating income in 2025. The remainder comes from net fees and commissions, primarily from current accounts and other banking services. Geographically, PTSB operates exclusively within the Republic of Ireland, serving over a million customers through a nationwide network of branches, digital platforms, and intermediary broker channels. The bank's competitive position is defined by its status as one of the pillar retail banks in the highly concentrated Irish banking market, maintaining a mortgage market share of approximately 20%.
