Material Changes vs. Prior Period

- Revenue Composition: Net fee income reached a record €10.0bn (+8% constant €), while Net Interest Income (NII) remained stable at €33.8bn (-2% constant €) due to a challenging interest rate environment, partially offset by volume growth.
- Efficiency Gains: The efficiency ratio improved significantly to 41.3%, down 450 basis points from the prior year, reflecting €90mn in technology efficiencies in 9M'25 alone.
- Argentina Impact: Results include Argentina in current euros to mitigate hyperinflation distortions. Excluding Argentina, NII grew 3% YoY and revenue grew 4% YoY.

Guidance, Outlook, and Risks
Guidance and Targets
- 2025 Targets: Management remains on track to beat updated Investor Day 2025 targets, including a RoTE post-AT1 of ~16.5% and double-digit EPS growth.
- Shareholder Remuneration: The bank intends to distribute approximately 50% of reported profit via cash dividends and share buybacks. A total share buyback target of at least €10bn for 2025-2026 was confirmed, including proceeds from the Santander Polska sale.
- Dividends: A cash dividend of €11.50 cents per share was approved in September 2025, to be paid in November 2025.
Risks and Contingencies
- Forward-Looking Statements: Results are subject to economic downturns, inflation, geopolitical instability (wars in Ukraine/Middle East), and regulatory changes.
- Operational Risks: Exposure to cyberattacks, data breaches, and operational losses.
- Argentina: Significant measurement uncertainties remain regarding the Argentine economy and exchange rate volatility, though the bank has adjusted its reporting methodology.
- Sustainability: Sustainability metrics are unaudited and subject to evolving standards and measurement uncertainties.
Investor Verification Checklist
- Poland Disposal: Verify the final closing conditions and capital release timing for the 49% stake sale to Erste Group, which impacts the €10bn buyback target.
- Argentina Methodology: Confirm the continued application of the official exchange rate vs. alternative rates for Argentina reporting and its impact on NII volatility.
- Regulatory Approvals: Monitor regulatory approvals for the TSB Banking Group acquisition and the Poland transaction.
- Capital Allocation: Track the execution of the €10bn share buyback program and the specific timing of the additional buybacks linked to the Poland sale proceeds.
- Cost of Risk: Monitor the Cost of Risk (CoR) trend, particularly in Brazil and Mexico, where model updates and macro conditions may influence provisions.
