Results Attributable profit in H1 2025 was EUR 3,687 million, 9% higher year-on-year, in part favoured by the temporary levy on revenue earned in Spain recorded in full in Q1 2024 (accrued quarterly in 2025). In constant euros profit rose 14% year-on-year, by line: • Total income increased 2%, mainly driven by positive performances in net fee income and a lower hyperinflation adjustment in Argentina. Net interest income also performed well, improving in a complex environment across most countries. However, it was flat year-on-year due to Argentina, which was heavily impacted by the decline in interest rates in the last twelve months. If we exclude Argentina, net interest income increased 3%, driven by a lower cost of deposits in Chile, higher mortgage profitability and a lower cost of deposits in the UK, volumes and lower cost of deposits in Mexico and higher activity in Poland.

Our more targeted products and services offering contributed to 8% net fee income growth, mainly driven by insurance, mutual funds and FX. By country, net fee income increased particularly in Argentina, Mexico and the UK.
