Banco Santander, S.A., ("Santander") in accordance with the provisions of the securities market legislation, communicates the following:

INSIDE INFORMATION

The results of the Supervisory Review and Evaluation Process ("SREP") have now been confirmed and Santander has been informed by the European Central Bank ("ECB") of its decision regarding the minimum prudential capital requirements effective as of 1 March 2022.

The ECB's decision establishes a Pillar 2 ("P2R") requirement of 1.50%, at an individual and a consolidated level, of which at least 0.84% must be covered with Common Equity Tier 1 capital ("CET1"). This requirement remains unchanged from the last SREP decision effective on 1 January 2020.

The P2R requirement, when added to the Pillar 1 requirements, the capital conservation buffer, the requirement derived from the consideration of Santander as a global systemic financial institution, and the countercyclical capital buffer, determines the total minimum prudential capital requirements. The following table shows the minimum CET1 capital and total capital requirements, as well as Santander's ratios as of 31 December 2021, on a phased-in basis: [1]

As described in the table above, Santander maintains a surplus of capital over these requirements, both at a consolidated and an individual level.  These capital requirements do not imply any limitation to the distribution or payment to the holders of Santander's Additional Tier 1 securities.
