Guidance, Outlook, and Risks
- Capital Position: The CET1 ratio of 13.46% is well above the 12-13% operating range and the minimum requirement of 9.83%. The distance to the Minimum Distributable Amount (MDA) is 334 basis points.

- Funding Plan: The 2025 funding plan was executed with €40.2 billion issued in public markets. The 2026 plan is pre-Webster acquisition and subject to market conditions.
- Key Risks:
- Geopolitical & Economic: Uncertainties regarding wars in Ukraine and the Middle East, inflation, and potential economic downturns.
- Operational: Exposure to cyberattacks, data breaches, and operational risks.
- Regulatory: Changes in capital and liquidity requirements, including the activation of a 0.50% countercyclical buffer in Spain in October 2025.
- Market: Interest rate volatility, foreign exchange fluctuations, and credit spread shifts.
- Forward-Looking Statements: Management cautions that future results may differ materially from projections due to the factors listed above. Sustainability information is subject to significant measurement uncertainties.
Investor Verification Checklist
- Argentina Hyperinflation: Verify the impact of the alternative exchange rate applied between Q2 2024 and Q1 2025 on reported figures and the current treatment of Argentine assets.
- Santander Polska Sale: Confirm the timeline and financial impact of the 49% stake sale to Erste Group, noting that current figures still include the subsidiary on an underlying basis.
- Brazil Performance: Investigate the drivers behind the 10.5% decline in underlying attributable profit in Brazil despite stable loan growth.
- Regulatory Buffers: Review the specific impact of the new 0.50% countercyclical buffer in Spain on the Group's capital requirements.
- Webster Acquisition: Assess the status and potential financial impact of the pending Webster acquisition, which is noted as a factor for the 2026 funding plan.
