OTHER MATERIAL INFORMATION

Banco Santander reports the results it has obtained in the most recent stress test exercise carried out by the European Banking Authority (EBA) and the European Central Bank (ECB).

The exercise covered a three-year period (end 2020 - end 2023) with two scenarios (baseline and adverse) applied to the consolidated perimeter of Santander Group. The CET1 ratio is a financial solvency ratio introduced in 2010 with the Basel III Accord, the implementation of which is being carried out progressively by financial institutions, pursuant to the transitional implementation schedules of the Capital Requirements Directive and Regulation, and the International Financial Reporting Standard (IFRS) 9. During the phase-in period of these regulations, in addition to the CET1 Phased-in ratio (a capital ratio calculated pursuant to the transitional regime), which is the legally binding ratio, the CET1 Fully Loaded ratio (a capital ratio calculated assuming a full implementation of the aforementioned regulations) is also used for information purposes.

The stress test exercise results in the following projected capital ratios for Santander Group for the periods and scenarios considered. A comparison of these projected ratios with the data at the end of 2020 in terms of both the CET1 Fully Loaded ratio (11.89%) and the CET1 Phased-in ratio (12.34%) is also included in brackets:
