Changes to Group reporting 10 February 2026

Important information Non - IFRS and alternative performance measures Banco Santander, S . A . (“Santander”) cautions that this presentation may contain financial information prepared according to International Financial Reporting Standards (IFRS) and taken from our consolidated financial statements, as well as alternative performance measures (APMs) as defined in the Guidelines on Alternative Performance Measures issued by the European Securities and Markets Authority (ESMA) on 5 October 2015 , and other non - IFRS measures . The APMs and non - IFRS measures were calculated with information from Grupo Santander ; however, they are neither defined or detailed in the applicable financial reporting framework nor audited or reviewed by our auditors . We use the APMs and non - IFRS measures when planning, monitoring and evaluating our performance . We consider them to be useful metrics for our management and investors to compare operating performance between accounting periods . Nonetheless, the APMs and non - IFRS measures are supplemental information ; their purpose is not to substitute the IFRS measures . Furthermore, companies in our industry and others may calculate or use APMs and non - IFRS measures differently, thus making them less useful for comparison purposes . APMs using environmental, social and governance labels have not been calculated in accordance with the Taxonomy Regulation or with the indicators for principal adverse impact in SFDR . For more details on APMs and non - IFRS measures, please see the 2024 Annual Report on Form 20 - F filed with the U . S . Securities and Exchange Commission (the SEC) on 28 February 2025 ( https : //www . santander . com/content/dam/santander - com/en/documentos/informacion - sobre - resultados - semestrales - y - anuales - suministrada - a - la - sec/ 2025 /sec - 2024 - annual - 20 - f - 2024 - en . pdf), as well as the section “Alternative performance measures” of Banco Santander, S .

(Santander) Q 4 2025 Financial Report, published on 3 February 2026 ( https : //www . santander . com/en/shareholders - and - investors/financial - and - economic - information#quarterly - results) . Forward - looking statements Santander hereby warns that this presentation may contain 'forward - looking statements', as defined by the US Private Securities Litigation Reform Act of 1995 . Such statements can be understood through words and expressions like 'expect', 'project', 'anticipate', 'should', 'intend', 'probability', 'risk', 'VaR', 'RoRAC', 'RoRWA', 'TNAV', 'target', 'goal', 'objective', 'estimate', 'future', 'ambition', 'aspiration', 'commitment', 'commit', 'focus', 'pledge' and similar expressions . They include (but are not limited to) statements on future business development, shareholder remuneration policy and NFI . However, risks, uncertainties and other important factors may lead to developments and results that differ materially from those anticipated, expected, projected or assumed in forward - looking statements . The important factors below (and others mentioned in this presentation), as well as other unknown or unpredictable factors, could affect our future development and results and could lead to outcomes materially different from what our forward - looking statements anticipate, expect, project or assume : general economic or industry conditions (e . g . , an economic downturn ; higher volatility in the capital markets ; inflation ; deflation ; changes in demographics, consumer spending, investment or saving habits ; and the effects of the wars in Ukraine, the uncertainties following the ceasefire agreement in the Middle East or the outbreak of public health emergencies in the global economy) in areas where we have significant operations or investments ; • exposure to operational risks, including cyberattacks, data breaches, data losses and other security incidents; • exposure to market risks (e.g., risks from interest rates, foreign exchange rates, equity prices and new benchmark indices); • potential losses from early loan repayment, collateral depreciation or counterparty risk; • political instability in Spain, the UK, other European countries, Latin America and the US; • changes in monetary, fiscal and immigration policies and trade tensions, including the imposition of tariffs and retaliatory responses; • legislative, regulatory or tax changes (including regulatory capital and liquidity requirements) and greater regulation prompted by financial crises; • acquisitions, integrations, divestitures and challenges arising from deviating management’s resources and attention from other strategic opportunities and operational matters; • climate - related conditions, regulations, targets and weather events; 2

• uncertainty over the scope of actions that may be required by us, governments and other to achieve goals relating to climate, environmental and social matters, as well as the evolving nature of underlying science and potential conflicts and inconsistencies among governmental standards and regulations . Important factors affecting sustainability information may materially differ from those applicable to financial information . Sustainability information is based on various materiality thresholds, estimates, assumptions, judgments and underlying data derived internally and from third parties . Sustainability information is thus subject to significant measurement uncertainties, may not be comparable to sustainability information of other companies or over time or across periods and its inclusion is not meant to imply that the information is fit for any particular purpose or that it is material to us under mandatory reporting standards . The sustainability information is for informational purposes only, without any liability being accepted in connection with it except where such liability cannot be limited under overriding provisions of applicable law ; • our own decisions and actions, including those affecting or changing our practices, operations, priorities, strategies, policies or procedures; and • changes affecting our access to liquidity and funding on acceptable terms, especially due to credit spread shifts or credit rating downgrade for the entire group or core subsidiaries. Forward looking statements are based on current expectations and future estimates about Santander’s and third - parties’ operations and businesses and address matters that are uncertain to varying degrees, including, but not limited to developing standards that may change in the future ; plans, projections, expectations, targets, objectives, strategies and goals relating to environmental, social, safety and governance performance, including expectations regarding future execution of Santander’s and third parties’ energy and climate strategies, and the underlying assumptions and estimated impacts on Santander’s and third - parties’ businesses related thereto ; Santander’s and third - parties’ approach, plans and expectations in relation to carbon use and targeted reductions of emissions ; changes in operations or investments under existing or future environmental laws and regulations ; and changes in government regulations and regulatory requirements, including those related to climate - related initiatives . Forward - looking statements are aspirational, should be regarded as indicative, preliminary and for illustrative purposes only, speak only as of the date of this presentation and are informed by the knowledge, information and views available on such date and are subject to change without notice . Banco Santander is not required to update or revise any forward - looking statements, regardless of new information, future events or otherwise, except as required by applicable law . Past performance does not indicate future outcomes Statements about historical performance or growth rates must not be construed as suggesting that future performance, share price or earnings (including earnings per share) will necessarily be the same or higher than in a previous period . Nothing mentioned in this presentation should be taken as a profit and loss forecast . Not a securities offer This presentation and the information it contains does not constitute an offer to sell nor the solicitation of an offer to buy any securities . Third Party Information In particular, regarding the data provided by third parties, neither Santander, nor any of its directors, managers or employees, either explicitly or implicitly, guarantees that these contents are exact, accurate, comprehensive or complete, nor are they obliged to keep them updated, nor to correct them in the case that any deficiency, error or omission were to be detected .

4 Executive summary Following completion of the Poland disposal in January 2026 and ahead of the upcoming Investor Day on 25 February, we will adjust our reporting effective from and including Q1 2026, as follows: Changes affecting underlying results and management metrics at the Group level, related to activity affected by the Poland disposal and to the classification of certain costs Reporting of Cards in Retail: we are positioning Payments, renamed Payment Solutions, as the Group’s payments platform business. As such, the Cards business will be reported in Retail, while Plard, our cards processing platform, remains in Payment Solutions Enhanced CoR, NPL ratio, NPL coverage ratio and Spain RoTE definitions, providing a more accurate reflection of the ratios, and impacts from the aforementioned adjustments to primary and secondary segment ratios 1 2 3 Primary segment definitions: in addition to the aforementioned changes, we are rebranding Consumer as Openbank and presenting a new business line structure within Wealth 4 These adjustments do not change the Group’s attributable profit, nor do they affect the Group’s targets announced in the Q4 2025 results presentation but rather enhance transparency, comparability and alignment with the way we manage the business Note: these adjustments will be applied to the financial information corresponding to 2024 and 2025 to enable comparisons across periods.

5 1 Changes affecting underlying results and management metrics at the Group level UNDERLYING P&L 2025, € mn (1) Change to the classification of certain costs which, until 2025, were reported in the ‘other results and provisions’ line. Bank levies were reported in other results as they were originally conceived as temporary charges, but attending to their structural nature linked to our activity, we are recording them in ‘other income’. (2) Loans and deposits excluding reverse repos and repos, respectively. 58,308 - 358 - 3,724 62,390 Total revenue - 26,410 - 1,721 +1,036 - 25,725 Total costs - 12,128 0 +283 - 12,411 LLPs - 834 +2,080 +473 - 3,387 Other results 13,152 0 - 949 14,101 Underlying profit 949 0 +949 0 Non - recurring items 14,101 0 0 14,101 Attributable profit Differences from… Published… … Poland … Costs …New …New Published… …New CHANGES RELATED TO POLAND DISPOSAL • The results associated with the activity affected by the Poland disposal will be reported in the ‘non - recurring items’ line in the underlying P&L – Global businesses are reported on an underlying basis only and will therefore exclude the results from Poland • Likewise, loans, deposits, RWAs and the management metrics no longer include Poland balances REPORTING OF CERTAIN COSTS 1 • Certain charges, mainly relating to bank levies and taxes applicable to the banking sector will now be recorded under ‘other operating income’ 1 • Other recurring operating costs , mainly relating to labour and legal processes, will be reclassified to the ‘total costs’ line BALANCE SHEET 2 Dec - 25, € bn MAIN FINANCIAL KPIs 2025 Differences from… Published… … Poland … Costs 45.3% 41.2% Efficiency ratio 984 0 - 41 1,024 Loans 15.2% 16.3% Underlying RoTE (post - AT1) 944 0 - 54 998 Deposits 16.3% 16.3% Statutory RoTE (post - AT1) 600 0 - 30 629 RWAs

6 • Given that our payments platform strategy is now largely established , we are positioning Payments, renamed Payment Solutions, as the Group’s payments platform business: - Results for our cards business and the related loan balances will be reclassified to Retail from Payments where it was previously recorded - Plard , our card processing platform, will remain in Payment Solutions , and will charge market - based fees to global businesses for card processing Note: figures after applying the adjustments described in slide 5 (changes related to Poland disposal and to the classification of certain costs).

7 • As Santander Spain doesn’t have its own accounting tangible equity 3 , we are updating the way we allocate a theoretical tangible equity to Spain to increase accuracy, based on: i) the amount required to reach a CET1 ratio of 13% and ii) the allocation of capital deductions and add - ons • Group and primary segment underlying RoTEs are affected by the Poland disposal adjustments and the reporting of Cards in Retail. Secondary segment underlying RoTEs are not affected, except for Spain 3 Impacts on primary and secondary segments’ underlying RoTEs (1) Digital Consumer Bank (Consumer) has been renamed Openbank. Subject to regulatory approvals. (2) This metric is not provided for Payment Solutions (‘Payments’) because, with Cards reported in Retail from 2026, we do not consider this to be a relevant metric for a payment platform business. (3) Santander Spain doesn’t have its own accounting tangible equity since it is booked under Banco Santander, S.A. with other units such as the Corporate Centre among others. Therefore, it is assigned a theoretical tangible equity. …New 20.4% 24.3% Spain 10.2% 10.2% UK 30.3% 30.3% Portugal 10.2% 10.2% US 22.0% 22.0% Mexico 15.3% 15.3% Brazil 19.7% 19.7% Chile 20.2% 20.2% Argentina Published… …New Published… Underlying RoTE (post - AT1), 2025 CHANGES TO GLOBAL BUSINESSES CHANGES TO COUNTRIES Underlying RoTE (post - AT1), 2025 17.1% 17.7% Retail 8.5% 8.6% Openbank 1 17.8% 19.1% CIB 61.5% 68.5% Wealth N/A 28.0% Payments 2 Underlying RoTE GROUP Statutory RoTE 16.3% 16.3% 15.2% 16.3% GROUP 15.2% 16.3% Underlying RoTE 16.3% 16.3% Statutory RoTE

31 CoR calculation: Brazil • CoR numerator (12m rolling LLPs) currently includes provisions arising from private fixed income products. However, the denominator (12m average net loans including reverse repos) does not include the exposure to these fixed income products, creating an imbalance between the numerator and the denominator • As a result, the CoR definition has been enhanced to include corporate exposures originated through private fixed income products in the denominator, providing a more accurate view of credit quality - 56bps vs. current criteria BRL mn, FY’25 … New Published… 27,798 27,798 Loan - loss provisions 1,131 1,131 o/w private fixed income 666,152 587,546 Average loans 78,607 0 o/w private fixed income CoR 4.73% 4.17% Note: with this change to the CoR calculation, we are aligning its definition to market standards in Brazil.
