 to submit special reports to supervisory authorities. The designation as a globally systemically important entity is made by the Basel Committee, jointly with the Financial Stability Board, using a methodology based on five indicators: size, cross-jurisdictional activity, interconnectedness with other financial entities, substitutability of financial services/financial infrastructure and complexity (weighted at 20% for each of the above categories). The methodology was revised in December 2021 incorporating, among other things, an additional score considering the SRM Member States as a single jurisdiction. The information necessary to evaluate the indicators is requested yearly from banks with leverage exposure exceeding €200 billion or from any other bank at the supervisor's discretion: 77 banks were considered in December 2023. These institutions are then required to publish the information before 30 April of the following year. With this information, a global indicator is created. The score obtained by each bank determines the size of the capital

buffer required of it, which is based on a set of buckets defined by the regulators (CET1 surcharge ranging from 1% to 3.5%). The Financial Stability Board (FSB) published in November 2024 its list of global systemically important banks based on the December 2023 data. This will be fully applicable in 2025. Meeting these requirements makes the Group a more robust bank than its domestic rivals. Santander is currently subject to a systemic capital surcharge of 1%, which will become fully effective in 2025.
