Guidance, Outlook, and Management Commentary
Shareholder Returns
The Board approved a new €5 billion share buyback program. Santander reiterated a commitment to distribute at least €10 billion from 2025-26 earnings and excess capital via buybacks. An interim cash dividend of 11.5 euro cents per share was paid in November 2025.
Strategic Outlook
- 2026 Targets (excluding Poland, TSB, Webster): Mid-single-digit revenue growth in constant euros; lower costs in constant euros; higher profits; stable cost of risk; CET1 ratio of 12.8-13%.
- 2027-2028 Outlook (post-Webster acquisition): Double-digit revenue growth in 2027; mid-teens profit growth in constant euros; CET1 ratio over 13%; RoTE exceeding 20% by 2028.
- Webster Acquisition: Expected to close in H2 2026. The transaction is projected to nearly double US RoTE to 18% by 2028 and deliver 7-8% EPS accretion for the group.
Risks and Contingencies
Management cited geopolitical volatility, potential delays in the Webster acquisition, integration risks, regulatory changes, and macroeconomic factors (inflation, interest rates) as key risks. The filing includes standard forward-looking statement disclaimers regarding the uncertainty of future results.
