Disclosure of reclassifications or changes in presentation [abstract]
Introduction, basis of presentation of the interim condensed consolidated financial statements and other information	Introduction, basis of presentation of the interim condensed consolidated financial statements and other information a) Introduction Banco Santander, S.A. ('the parent' or 'Banco Santander') is a private-law entity subject to the rules and regulations applicable to banks operating in Spain. The Bylaws and other public information of the Bank can be consulted at its registered office at Paseo de Pereda 9-12, Santander. In addition to the operations carried on directly by it, Banco Santander is the head of a group of subsidiaries that engage in various business activities and which compose, together with it, Grupo Santander ('Santander' or 'The Group'). Grupo Santander's interim condensed consolidated financial statements ('interim financial statements') for the six-month period ended 30 June 2022 were authorised and approved by Grupo Santander's directors at the board of directors meeting held on 27 July 2022 . Grupo Santander's consolidated annual accounts for year 2021 were approved by shareholders at Banco Santander annual general meeting on 1 April 2022. b) Basis of presentation of the interim financial statements Under Regulation (EC) n.º 1606/2002 of the European Parliament and of the Council of 19 July 2002 all companies governed by the law of an EU Member State and whose securities are admitted to trading on a regulated market of any Member State must prepare their consolidated financial statements for the years beginning on or after 1 January, 2005 in conformity with the International Financial Reporting Standards ('IFRS') previously adopted by the European Union ('EU-IFRS'). In order to adapt the accounting system of Spanish credit institutions with the principles and criteria established by the IFRS adopted by the European Union ('EU-IFRS'), the Bank of Spain published circular 4/2017, dated 27 November 2017, and subsequent changes, on Public and Confidential Financial Reporting Standards and Financial Statement Formats. The consolidated annual accounts for 2021 were authorised at the board of directors meeting on 24 February 2022 in compliance with International Financial Reporting Standards as adopted by the European Union, taking into account Bank of Spain Circular 4/2017, and subsequent modifications, using the basis of consolidation, accounting policies and measurement bases described in Note 2 to the aforementioned consolidated annual accounts and, accordingly, they presented fairly Grupo Santander’s consolidated equity and consolidated financial position at 31 December 2021 and the consolidated results of its operations, and the consolidated cash flows in 2021. The aforementioned consolidated annual accounts, which are included in Grupo Santander’s Form 6-K filed with the U.S. Securities and Exchange Commission on 8 April 2022, and these interim financial statements are also in compliance with International Financial Reporting Standards as issued by the International Accounting Standards Board ('IFRS-IASB', and together with EU-IFRS, 'IFRS'). These interim financial statements were prepared and are presented in accordance with International Accounting Standard (IAS 34), Interim Financial Reporting, for the preparation of interim financial statements in accordance with the provisions of article 12 of Royal Decree 1362 /2007 and taking into account the requirements of Circular 3/2018, of 28 June, of the Spanish National Securities Market Commission ('CNMV'). The aforementioned interim financial statements will be included in the half-year financial report for the first six months of 2022 to be presented by the Group in accordance with the Circular 3/2018. In accordance with IAS 34, the interim financial statements are intended only to provide an update on the content of the latest consolidated annual accounts authorised for issue, focusing on new activities, events and circumstances occurring during the first six months, and does not duplicate information previously reported in the latest consolidated annual accounts. Consequently, these interim financial statements do not include all the information that would be required for a complete set of consolidated annual accounts prepared in accordance with IFRS and, accordingly, for a proper comprehension of the information included in these interim financial statements, they should be read together with Grupo Santander’s consolidated annual accounts for the year ended 31 December 2021. Grupo Santander policies include presenting the interim financial statements for its use in the different markets using the Euro as its presentation currency. The amounts held in other currencies and the balances of entities whose functional currency is not the Euro, have been translated to the presentation currency in accordance with the criteria indicated in Note 2.a to the consolidated annual accounts for 2021. As indicated in that Note, for practical reasons, the balance sheet amount has been converted to the closing exchange rate, the equity to the historical type, and the income and expenses have been converted by applying the average exchange rate of the period; the application of such exchange rate or that corresponding to the date of each transaction does not lead to significant differences in the interim financial statements of Grupo Santander. The accounting policies and methods used in preparing these interim financial statements are the same as those applied in the consolidated annual accounts for 2021 taking into account the standards and interpretations with effective application date during the first six months of 2022, which are detailed below: – Amendment to IFRS 3 Business Combinations: to update the references to the Conceptual Framework for Financial Reporting and add an exception for the recognition of liabilities and contingent liabilities within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets and IFRIC 21 Levies. The amendments also confirm that an acquirer should not recognize contingent assets acquired in a business combination. Applicable from 1 January 2022. – Amendment to IAS 16 Property, Plant and Equipment: prevents an entity from deducting from the cost of an item of property, plant and equipment any revenue from the sale of finished goods while the entity is preparing the item for its intended use. It is also clear that an entity is "testing whether the asset is functioning properly" when evaluating the technical and physical performance of the asset. The financial performance of the asset should not be taken into account for this evaluation. Additionally, entities should disclose separately the amounts of income and expenses related to finished goods that are not the product of the entity's ordinary activities. Applicable from 1 January 2022. – Amendment to IAS 37 Provisions, Contingent Liabilities and Contingent Assets: clarifies that the direct costs of fulfilling a contract include both the incremental costs of fulfilling the contract and an allocation of other costs directly related to fulfilling contracts. Before recognising a separate provision for an onerous contract, the entity recognises any impairment loss that has occurred on assets used in fulfilling the contract. Applicable from 1 January 2022. – Amendment to IFRS Cycle (2018-2020): introduces minor amendments, applicable from 1 January 2022, to the following standards: • IFRS 9 Financial Instruments: clarifies which rates must be included in the 10% test for derecognition of financial liabilities. • IFRS 16 Leases: amendment to remove possible confusion regarding the treatment of leasing incentives in the application of IFRS 16 Leases. • IFRS 1, in relation to the first-time adoption of International Financial Reporting Standards, allows entities that have measured their assets and liabilities at the carrying amounts recorded in their parent's books to also measure any cumulative translation differences using the amounts reported by the parent. This amendment also applies to associates and joint ventures that have adopted the same exemption from IFRS 1. The aforementioned amendments to accounting standards have not had a significant effect on Grupo Santander’s financial statements. All accounting policies and measurement bases with a material effect on the interim financial statements for 30 June 2022 were applied in their preparation. By the time of the preparation and authorisation of these interim financial statements, there were no standards to be adopted by the European Union for the current year whose effective date of implementation by the IASB is after 1 January 2022. c) Use of critical estimates The consolidated results and the determination of the consolidated equity are sensitive to the accounting principles and policies, valuation criteria and estimates used by the directors of Banco Santander in preparing the interim financial statements. The main accounting principles, policies, and valuation criteria are indicated in note 2 of the consolidated annual accounts of the year 2021, except for those indicated in these interim financial statements due to the rules that have come into effect during the first six months of the year 2022. The interim financial statements contain estimates made by the senior management of Banco Santander and of the consolidated entities in order to quantify certain of the assets, liabilities, income, expenses and obligations reported in the consolidated entities. These estimates, which were made on the basis of the best information available, relate mainly to the following: 1. The income tax expense, which, in accordance with IAS 34, is recognised in interim periods based on the best estimate of the weighted average tax rate expected by Grupo Santander for the full financial year; 2. The impairment losses on certain assets – Financial assets at fair value through other comprehensive income, financial assets at amortised cost, non-current assets held for sale, investments in subsidiaries, joint ventures and associates, tangible assets and intangible assets; 3. The assumptions used in the calculation of the post-employment benefit liabilities and commitments and other obligations; 4. The useful life of the tangible and intangible assets; 5. The measurement of goodwill impairment arising on consolidation; 6. The calculation of provisions and the consideration of contingent liabilities; 7. The fair value of certain unquoted assets and liabilities; 8. The recoverability of deferred tax assets; and 9. The fair value of the identifiable assets acquired and the liabilities assumed in business combinations in accordance with IFRS 3. To update the above estimates, the Group's management has considered the situation of the war in Ukraine. The Group has no presence in Russia or Ukraine and its direct exposure to Russian and Ukrainian markets and assets are not material. The extent to which the conflict could ultimately impact the Group's results will depend on future developments, including subsequent sanctions that could eventually affect negatively to some Groups’ customers (those more closely related to Russia or Ukraine). Group's management has assessed the uncertainties caused by the current situation (high inflation, rise in interest rates, supply chain disruptions in more sensitive sectors, etc.) taking into account the best information available in order to anticipate the impact on the most relevant portfolios. Furthermore, Grupo Santander reinforced the monitoring of all risks, with special attention to Poland (due to its geographical situation). Overall, the most significant impacts have been in higher commodity prices, particularly energy, and lower household disposable income due to inflationary pressures. The main actions being taken by Santander have been: • Identification of potentially affected customers, specially by the increase in energy and oil prices, leveraging on risk playbooks • Cyber teams prepared for a possible contingency, as cyber threats have increased due to the conflict. • Sensitivity analysis to assess potential impacts and define action plans if needed. • Continuous revision, by the Compliance teams, of the correct application of the sanctions established by the international community. • Activation of the Special Situation Committee to oversee the potential effects of the conflict. In addition, the Group's Management has taken into account the current situation as a result of covid-19, which significantly affected the economic activity worldwide and, as a result, the Group's operations and financial results. In order to minimize the medium- and long-term economic impacts of the efforts made to contain the covid-19 pandemic, in 2020 and 2021, governments and economic and regulatory authorities of the main countries, in which the Group operates, launched a set of fiscal and monetary policy measures and other initiatives to mitigate the impact of the pandemic on the economy and to support companies and people. Likewise, Grupo Santander implemented a set of customer relief measures in full compliance with regulatory and supervisory recommendations. Santander continued to support its customers in the first six months of 2022, fostering their economic resilience in all the Group's geographies. In relation to the relief measures to tackle the pandemic effects, the Group’s total moratoria programmes granted have fully expired at the end of first half performing better than expected. Regarding government liquidity programmes, the Group is closely monitoring their performance as the grace periods established are reaching their end. Spain concentrates most of these types of programmes, with 87% of the grace periods expired and credit quality in line with expectations, with no concerning signs of deterioration. Lastly, the Group has partially and voluntarily aligned during the first half of 2022 the accounting definition of stage 3, as well as for the calculation of impairment provision models, to the New Definition of Default, incorporating the criteria defined by the EBA in its implementation guide of the definition of default, capturing the economic deterioration of the operations (days in default - on a daily basis – and materiality thresholds - minimum amount in arrears). The alignment of criteria has been done taking into account the criteria of IFRS 9 as well as the accounting principles of unbiased presentation of financial information. There has been an increase in the default rate at around 19 basis points, with no material impact on the provision figures for credit risk. During the first six months ended 30 June 2022, there have been no additional significant changes in the estimates made at the end of 2021, other than those indicated in these interim financial statements. d) Contingent assets and liabilities Note 2.o to Grupo Santander's consolidated annual accounts for the year ended 31 December 2021 includes information on the contingent assets and liabilities at that date. There were no significant changes in Grupo Santander's contingent assets and liabilities from 31 December 2021 to the date of formal preparation of these interim financial statements. e) Comparative information The comparative information in Note 8 as of 31 December 2021 has been restated in accordance with the reallocation of the total amount of goodwill described in said note. In addition, the information in Note 12 regarding the Group´ segments information corresponding to the six months period ended 30 June 2021 has been restated in accordance with the Group's new organizational structure, as required by IFRS 8. Additionally, the information in Note 15 for June 2021 has been restated in accordance with the Group's standardization criteria. In order to interpret the changes in the balances with respect to 31 December 2021, it is necessary to take into consideration the exchange rate effect arising from the volume of foreign currency balances held by the Group in view of its geographic diversity (Note 50.b to the consolidated annual accounts for the year ended 31 December 2021) and the impact of the appreciation/depreciation of the various currencies against the euro in the first six months of 2022: Mexican peso (9.87%), US dollar (8.40%), Brazilian real (15.47%), Argentine peso (-11.10%), Pound sterling (-2.30%), Chilean peso (-1.53%) and Polish zloty (-2.22%); as well as the evolution of the average exchange rates between comparable periods: Mexican peso (9.82%), US dollar (10.32%), Brazilian real (17.23%), Pound sterling (3.01%), Chilean peso (-3.83%) and Polish zloty (-2.11%). f) Seasonality of the Grupo Santander’s transactions The business activities carried on by Grupo Santander entities, and their transactions are not cyclical or seasonal in nature. Therefore, no specific disclosures are included in these explanatory notes to the interim financial statements for the first six months ended 30 June 2022. g) Materiality In determining the note disclosures to be made on the various items in the interim financial statements or other matters, Grupo Santander, in accordance with IAS 34, took into account their materiality in relation to the interim financial statements for the first six months ended 30 June 2022. h) Events after the reporting period On 12 July 2022 the Spanish government announced its plans to impose new taxes on banks and energy companies. Particularly, regarding the new levy to Spanish banks, the only information available at the date of these interim financial statements is that this new tax would apply temporarily to domestic activities in 2022 and 2023. The proposal is subject to parliamentary approval and needs development to calculate the potential impact on profits. On 14 July 2022 the President of Poland signed a "Payment Holidays Act" on crowdfunding for businesses and support for borrowers. The impact of payment holidays solutions introduced in the execution of this act that will be accounted for in the third quarter is estimated at approximately PLN 1,400 million (EUR 300 million) in the gross financial results (assuming that 50% of eligible customers will avail of this solution). This impact will depend, among others, on the number of customers who will benefit from the solution, the number of instalments suspended by each of these customers and the moment they start to benefit from the "payment holidays".

Disclosure of detailed information about business combination [abstract]
Santander Group	Santander Group Appendices I, II and III to the consolidated annual accounts for the year ended 31 December 2021 provide relevant information on Grupo Santander companies at that date and on the companies accounted for under the equity method. Also, Note 3 to the aforementioned consolidated annual accounts includes a description of the most significant acquisitions and disposals of companies performed by Grupo Santander in 2021, 2020 and 2019. The most significant transactions carried out during the first six months of 2022 or pending execution at 30 June 2022 are described below: Purchase by SHUSA for shares of Santander Consumer USA In August 2021 Santander Holdings USA, Inc. ('SHUSA') and Santander Consumer USA Holdings Inc. ('SC') entered into a definitive agreement pursuant to which SHUSA acquired all outstanding shares of common stock of SC not already owned by SHUSA via an all-cash tender offer (the 'Tender Offer') for USD 41.50 per SC common share (the 'Offer Price'), followed by a second-step consisting of a merge (together with the Offer, the 'Transaction') in which a wholly owned subsidiary of SHUSA was merged with and into SC, with SC surviving as a wholly owned subsidiary of SHUSA, and all outstanding shares of common stock of SC not tendered in the Tender Offer were converted into the right to receive the Offer Price in cash. The Offer Price represented a 14% premium to the closing price of SC common stock of USD 36.43 as of 1 July 2021, the last day prior to the announcement of SHUSA’s initial offer to acquire the remaining outstanding shares of SC’s common stock. On 31 January 2022, after completion of the customary closing conditions, the Transaction was performed and SHUSA increased its share up to the 100% of SC's common stock. The transaction has meant a disbursement of USD 2,510 million (around EUR 2,239 million) for the Group, with a decrease of reserves of EUR 487 million and a decrease of EUR 1,752 million of minority interests. Acquisition of Amherst Pierpont, a U.S. fixed-income broker dealer On 15 July 2021, Santander Holdings USA, Inc. reached an agreement to acquire Amherst Pierpont Securities, a market-leading independent fixed-income and structured products broker dealer, through the acquisition of its parent holding company, Pierpont Capital Holdings LLC, for a total consideration of approximately USD 450 million (around EUR 405 million). The operation has been closed on 11 April 2022 once the pertinent regulatory approvals have been obtained. Immediately after the acquisition, SHUSA has lent financing to the company for an amount of USD 163 million (approximately EUR 147 million), which the company will use to cancel debt with third parties. Amherst Pierpont will become part of Santander Corporate & Investment Banking (Santander CIB) Global business line. The business combination has meant the recognition of a goodwill of EUR 158 million and EUR 24 million of intangible assets (mainly relationships with customers) identified in the purchase price allocation, without other relevant value adjustments to net assets of the business. The amount contributed by this business to the group net attributable profit since the date of acquisition is not material. Similarly, the result that this business would have brought to the group if the transaction had been carried out on January 1, 2022 is also immaterial.

In addition, during the first six months of 2022 EUR 169 million were recognized for losses in the income statement due to renegotiation or contractual modifications (no amount being recognized in the first six months of 2021). Considering these amounts, the recorded impairment of financial assets at amortised cost is EUR 4,762 million and EUR 3,785 million during the first six months of 2022 and 2021, respectively. c) Impaired assets of financial assets at amortised cost portfolio The movement during the first six months ended 30 June 2022 and 2021, in the balance of financial assets classified at amortised cost and considered impaired by reason for the credit risk is as follows: EUR million 30-06-2022 30-06-2021 Balance as at beginning of period 31,848 31,168 Net additions 5,710 4,842 Written-off assets (5,682) (4,353) Exchange differences and other 850 819 Balance at end of period 32,726 32,476 This amount, after deducting the related allowances, represents Grupo Santander's best estimate of the discounted value of the flows that are expected to be recovered from the impaired assets. d) Guarantees received Following is the breakdown of the value of the guarantees received to ensure the collection of the financial assets that comprise the heading of financial assets at amortized cost, distinguishing between real guarantees and other guarantees as of 30 June 2022 and 31 December 2021: EUR million 30-06-2022 31-12-2021 Real guarantees value 625,070 595,038 Of which: Impaired 11,411 11,371 Other guarantees value 96,091 87,791 Of which: Impaired 1,957 1,873 Total value of the guarantees received 721,161 682,829 e) Fair value of financial assets not measured at fair value Following is a comparison of the carrying amounts of Grupo Santander’s financial assets measured at other than fair value and their respective fair values at 30 June 2022 and 31 December 2021: EUR million 30-06-2022 31-12-2021 Carrying amount Fair value Carrying amount Fair value Loans and advances 1,072,170 1,065,917 1,002,190 1,006,711 Debt instruments 57,520 55,111 35,708 35,378 ASSETS 1,129,690 1,121,028 1,037,898 1,042,089 The main valuation methods and inputs used in the estimation of the fair value of the financial assets of the previous table are detailed in Note 50.c of the consolidated annual accounts for the year 2021.

Intangible assets	Intangible assets The detail of Intangible Assets - Goodwill at 30 June 2022 and 31 December 2021, based on the cash-generating units giving rise thereto, is as follows: EUR million 30-06-2022 31-12-2021 Banco Santander (Brazil) 3,416 2,930 SAM Investment Holdings Limited 1,444 1,444 Santander Consumer Germany 1,304 1,304 Santander Bank Polska 1,071 1,095 Santander Consumer USA 1,062 979 Santander Portugal 1,040 1,040 Santander España 998 998 Santander Bank, National Association 697 643 Santander UK 618 633 Banco Santander - Chile 508 516 Grupo Financiero Santander (Mexico) 463 422 Getnet Brazil 330 287 Ebury 308 — Santander Consumer Nordics 218 224 Other entities 400 198 Total Goodwill 13,877 12,713 During the first half of 2022, the Group has reallocated the goodwill initially assigned to certain cash-generating units (CGUs), being the main modification the one made in the Banco Santander (Brazil) CGU, after the spin-off of Getnet Brasil and subsequent contribution of the Group's stake in this company to PagoNxt, SL. This reassignment has been made based on the relative values of the split units, none of them presenting evidence of impairment prior to the reassignment. The consolidated figures were not modified by this fact. In addition, during the first six months of 2022 there has been an increase in goodwill of EUR 1,164 million, of which EUR 643 million correspond to exchange differences and the rest to business combinations. Exchange differences (see Note 11), in accordance with current regulations, have been recorded with a credit to the heading Other comprehensive income - Items that can be reclassified in results- Foreign currency translation of equity through the Statement of recognized income and expenses consolidated summary. As for the main business combinations of the period, the Group completed the acquisition of Amherst Pierpont Securities in April (see Note 2). Additionally, in the same month, it took control of Ebury after disbursing USD 173 million (EUR 206 million) to thus reach a 66.5% participation in its capital. Note 17 of the consolidated annual accounts for the year ended 31 December 2021 includes detailed information on the procedures followed by Grupo Santander to analyse the potential impairment of the goodwill recognised with the respect to its recoverable amount and to recognise the related impairment losses, where appropriate. The accounting standard (IAS 36) requires that a cash‑generating unit to which goodwill has been allocated is tested for impairment annually, and whenever there is an indication that the unit may be impaired. Accordingly, based on the analysis performed of the available information on the performance of the various cash-generating units which might evidence the existence of indicators of impairment, Grupo Santander's directors concluded that in the first six months of 2022 there were no impairment losses which required recognition (see Note 1.c).

Provisions [abstract]
Provisions	Provisions a) Provisions for Pensions and other post-retirements obligations and Other long term employee benefits The variation experienced by the balance of the Pensions and other post-retirements obligations and other long-term employee benefits from 31 December 2021 to 30 June 2022, is mainly due to lower net actuarial losses as a result of changes in actuarial assumptions (see Note 11.d). b) Provisions for taxes and other legal contingencies and Other provisions Set forth below is the detail, by type of provision, of the balances at 30 June 2022 and at 31 December 2021 of Provisions for taxes and other legal contingencies and Other provisions. The types of provision were determined by grouping together items of a similar nature: EUR million 30-06-2022 31-12-2021 Provisions for taxes 678 564 Provisions for employment-related proceedings (Brazil) 381 328 Provisions for other legal proceedings 1,183 1,104 Provision for customer remediation 351 745 Regulatory framework-related provisions 18 36 Provision for restructuring 683 749 Other 957 897 4,251 4,423 Relevant information is set forth below in relation to each type of provision shown in the preceding table: The provisions for taxes include provisions for tax-related proceedings. The provisions for employment-related proceedings (Brazil) relate to claims filed by trade unions, associations, the prosecutor’s office and ex-employees claiming employment rights to which, in their view, they are entitled, particularly the payment of overtime and other employment rights, including litigation concerning retirement benefits. The number and nature of these proceedings, which are common for banks in Brazil, justify the classification of these provisions in a separate category or as a separate type from the rest. The Group calculates the provisions associated with these claims in accordance with past experience of payments made in relation to claims for similar items. When claims do not fall within these categories, a case-by-case assessment is performed and the amount of the provision is calculated in accordance with the status of each proceeding and the risk assessment carried out by the legal advisers. The provisions for other legal proceedings include provisions for court, arbitration or administrative proceedings (other than those included in other categories or types of provisions disclosed separately) brought against Santander Group companies. The provisions for customer remediation include mainly the estimated cost of payments to remedy errors relating to the sale of certain products in the UK, as well as the estimated amount related to the floor clauses of Banco Popular Español, S.A.U. To calculate the provision for customer remediation, the best estimate of the provision made by management is used, which is based on the estimated number of claims to be received and, of these, the number that will be accepted, as well as the estimated average payment per case. The regulatory framework-related provisions include Bank Levy in the UK and in Poland the provision related to the Banking Tax. The provisions for restructuring include only the costs arising from restructuring processes carried out by the various Group companies. Lastly, the 'Other' heading contains very atomized and individually insignificant provisions, such as the provisions to cover the operational risk. Qualitative information on the main litigation is provided in Note 10.c. The Group's general policy is to record provisions for tax and legal proceedings in which the Group assesses the chances of loss to be probable and the Group does not record provisions when the chances of loss are possible or remote. Grupo Santander determines the amounts to be provided for as its best estimate of the expenditure required to settle the corresponding claim based, among other factors, on a case-by-case analysis of the facts and the legal opinion of internal and external counsel or by considering the historical average amount of the loss incurred in claims of the same nature. The definitive date of the outflow of resources embodying economic benefits for the Group depends on each obligation. In certain cases, the obligations do not have a fixed settlement term and, in others, they depend on legal proceedings in progress. The changes in provisions arising from civil contingencies and legal nature are disclosed in this note. The main changes in provisions in the first six months of 2022 are as follows: With respect to provisions for labor and other legal proceedings, in Brazil, provisions of EUR 109 million and EUR 66 million were recorded, making payments of EUR 107 million and EUR 90 million, respectively. With respect to provisions for customer compensation, and based on the best information available, the gross amount of mortgage loans denominated and indexed to foreign currencies in Poland has been adjusted, in accordance with IFRS 9, by the new estimated cash flows, as described in Note 10 c. On the regulatory framework side, in Poland, EUR 76 million were recorded and paid in the period of six months of 2022 under the said regulatory framework. c) Litigation and other matters i. Tax-related litigation At 30 June 2022 the main tax-related proceedings concerning the Group were as follows: • Legal actions filed by Banco Santander (Brasil) S.A. and other Group entities to avoid the application of Law 9.718/98, which modifies the basis to calculate PIS and COFINS social contribution, extending it to all the entities income, and not only to the income from the provision of services. In relation of Banco Santander (Brasil) S.A. process, in May 2015 the Federal Supreme Court (FSC) admitted the extraordinary appeal filed by the Federal Union regarding PIS, and dismissed the extraordinary appeal lodged by the Brazilian Public Prosecutor's Office regarding COFINS contribution, confirming the decision of Federal Regional Court favourable to Banco Santander (Brasil) S.A. of August 2007. The appeals filed by the other entities before the Federal Supreme Court, both for PIS and COFINS, are still pending. These claims are fully provisioned. • Banco Santander (Brasil) S.A. and other Group companies in Brazil have appealed against the assessments issued by the Brazilian tax authorities questioning the deduction of loan losses in their income tax returns (IRPJ and CSLL) in relation to different administrative processes of various years on the ground that the requirements under the applicable legislation were not met. The appeals are pending decision in CARF. No provision was recognised in connection with the amount considered to be a contingent liability. • Banco Santander (Brasil) S.A. and other Group companies in Brazil are involved in administrative and legal proceedings against several municipalities that demand payment of the Service Tax on certain items of income from transactions not classified as provisions of services. There are several cases in different judicial instances. A provision was recognised in connection with the amount of the estimated loss. • Banco Santander (Brasil) S.A. and other Group companies in Brazil are involved in administrative and legal proceedings against the tax authorities in connection with the taxation for social security purposes of certain items which are not considered to be employee remuneration. There are several cases in different judicial instances. A provision was recognised in connection with the amount of the estimated loss. • In May 2003 the Brazilian tax authorities issued separate infringement notices against Santander Distribuidora de Títulos e Valores Mobiliarios, Ltda. (DTVM, actually Santander Brasil Tecnología S.A.) and Banco Santander (Brasil) S.A. in relation to the Provisional Tax on Financial Movements (CPMF) of the years 2000 to 2002. The administrative discussion ended unfavourably for both companies, and on July 3, 2015, filed a lawsuit requesting the cancellation of both tax assessments. The lawsuit was judged unfavourably in first instance. Therefore, both plaintiffs appealed to the court of second instance. On December 2020, the appeal was decided unfavourably. Against the judgment, the bank filed a motion for clarification which has not been accepted. Currently it is appealed to higher courts. There is a provision recognized for the estimated loss. • In December 2010 the Brazilian tax authorities issued an infringement notice against Santander Seguros S.A. (Brazil), currently Zurich Santander Brasil Seguros e Previdência S.A., as the successor by merger to ABN AMRO Brasil dois Participações S.A., in relation to income tax (IRPJ and CSLL) for 2005, questioning the tax treatment applied to a sale of shares of Real Seguros, S.A. The administrative discussion ended unfavourably, and the CARF decision has been appealed at the Federal Justice. As the former parent of Santander Seguros S.A. (Brasil), Banco Santander (Brasil) S.A. is liable in the event of any adverse outcome of this proceeding. No provision was recognised in connection with this proceeding as it is considered to be a contingent liability. • In November 2014 the Brazilian tax authorities issued an infringement notice against Banco Santander (Brasil) S.A. in relation to corporate income tax (IRPJ and CSLL) for 2009 questioning the tax-deductibility of the amortisation of the goodwill of Banco ABN AMRO Real S.A. performed prior to the absorption of this bank by Banco Santander (Brasil) S.A., but accepting the amortisation performed after the merger. Actually it is appealed before the Higher Chamber of CARF. No provision was recognised in connection with this proceeding as it was considered to be a contingent liability. • Banco Santander (Brasil) S.A. has also appealed against infringement notices issued by the tax authorities questioning the tax deductibility of the amortisation of the goodwill arising on the acquisition of Banco Comercial e de Investimento Sudameris S.A from years 2007 to 2012. No provision was recognised in connection with this matter as it was considered to be a contingent liability. • Banco Santander (Brasil) S.A. and other companies of the Group in Brazil are undergoing administrative and judicial procedures against Brazilian tax authorities for not admitting tax compensation with credits derived from other tax concepts, not having registered a provision for the amount considered to be a contingent liability. • Banco Santander (Brasil) S.A. is involved in appeals in relation to infringement notices initiated by tax authorities regarding the offsetting of tax losses in the CSLL (‘Social Contribution on Net Income’) of year 2009. The appeal is pending decision in CARF. No provision was recognised in connection with this matter as it is considered to be a contingent liability. • Brazilian tax authorities have issued infringement notices against Getnet Adquirência e Serviços para Meios de Pagamento S.A and Banco Santander (Brasil) S.A. as jointly liable in relation to corporate income tax (IRPJ and CSLL) for 2014 to 2018 questioning the tax-deductibility of the amortization of the goodwill from the acquisition of Getnet Tecnologia Proces S.A., considering that the company would not have complied with the legal requirements for such amortization. A defense against the tax assessment notices were submitted, and the appeal is pending decision in CARF. No provision was recognized as it is considered to be a contingent liability. The total amount for the aforementioned Brazil lawsuits that are fully provisioned is EUR 1,024 million, and for lawsuits that qualify as contingent liabilities is EUR 4,530 million. • Banco Santander appealed before European Courts the Decisions 2011/5/CE of 28 October 2009 (First Decision), and 2011/282/UE of 12 January 2011 (Second Decision) of the European Commission, ruling that the deduction of the financial goodwill regulated pursuant to Article 12.5 of the Corporate Income Tax Law constituted illegal State aid. On October 2021 the Court of Justice has definitively confirmed these Decisions. The dismissal of the appeal, that only affects these two decisions, has no effect on equity. At the date of approval of these interim financial statements certain other less significant tax-related proceedings are also in progress. ii. Non-tax-related proceeding s At 30 June 2022 the main non-tax-related proceedings concerning the Group were as follows: • Payment Protection Insurance (PPI): In recent years Santander UK plc has processed customer claims associated with the sale of payment protection insurance (“PPI”), derived from the Financial Conduct Authority guidelines. As of 30 June 2022 there is no provision related to those claims as the deadline for presenting them has already expired. However, customers can still commence in-court litigation for the mis-sale of PPI and a provision for the best estimate of any obligation to pay compensation in respect of current and future claims is recognized for this purpose. In addition, there is a legal dispute regarding allocation of liability for pre-2005 PPI policies underwritten by two entities (“Axa France”) that Axa Group acquired from Genworth Financial International Holdings, Inc. in September 2015. The dispute involves Santander Cards UK Limited (formerly known as GE Capital Bank Limited which was acquired by Banco Santander, S.A. from GE Capital group in 2008) which was the distributor of the policies in dispute and Santander Insurance Services UK Limited (the Santander Entities). In July 2017, the Santander Entities notified Axa France that they did not accept liability for losses on PPI policies relating to the referred period. Santander UK plc entered in a Complaints Handling Agreement –that included a standstill agreement- agreeing to handle complaints on Axa France, whilst Axa France accepted paying redress assessed to be due to relevant policyholders on a without prejudice basis. After the termination of the Complaints Handling Agreement, on 30 December 2020 Axa France provided written notice to the Santander Entities to terminate the standstill agreement. On 5 March 2021, the Santander Entities were served with a Claim Form and Brief Details of Claim by Axa France, claiming that the Santander Entities are liable to reimburse Axa France for pre-2005 PPI mis-selling losses, currently estimated at GBP 636 million (EUR 739 million). On 22 March 2021, the Santander Entities acknowledged service of the claim and notified the court of their intention to defend the claim in full and issued an application for Axa Frances’s claim to be struck out/summarily dismissed, which was heard by the Commercial Court on 22 and 23 February 2022 with judgement reserved. Judgment was handed down by the Commercial Court on 12 July 2022. The Commercial Court upheld a significant part of the Santander Entities’ strike-out plead. Both parties can seek permission to appeal this decision. In any event, notwithstanding any appeal, there are still ongoing factual issues to be resolved during the trial, which may have legal consequences including in relation to liability. These issues create uncertainties which mean that it is difficult to reliably predict the outcome or the timing of the resolution of the matter. The provision includes our best estimate of the Santander Entities’ liability for this matter. • Delforca: dispute arising from equity swaps entered into by Gaesco (now Delforca 2008, S.A.) on shares of Inmobiliaria Colonial, S.A. Banco Santander, S.A. is claiming to Delforca before the Court of Barcelona in charge of the bankruptcy proceedings, a total of EUR 66 million from the liquidation resulting from the early termination of financial transactions due to Delforca's non-payment of the equity swaps. In the same bankruptcy proceedings, Delforca and Mobiliaria Monesa have in turn claimed the Bank to repay EUR 57 million, which the Bank received for the enforcement of the agreed guarantee, as a result of the aforementioned liquidation. On 16 September 2021 the Commercial Court Number 10 of Barcelona has ordered Delforca to pay the Bank EUR 66 million plus EUR 11 million in interest and has dismissed the claims filed by Delforca. This decision has been appealed by Delforca, Mobiliaria Monesa and the bankruptcy administrator. The appeal which the Bank has already opposed to will be resolved by the Provincial Court of Barcelona. Separately, Mobiliaria Monesa, S.A. (parent of Delforca) filed in 2009 a civil procedure with the Courts of Santander against the Bank claiming damages that have not been specified to date. The procedure is suspended. • Former employees of Banco do Estado de São Paulo S.A., Santander Banespa, Cia. de Arrendamiento Mercantil: claim initiated in 1998 by the association of retired Banespa employees (AFABESP) requesting the payment of a half-yearly bonus contemplated in the by-laws of Banespa in the event that Banespa obtained a profit and that the distribution of this profit were approved by the Board of Directors. The bonus was not paid in 1994 and 1995 since Banespa had not made a profit during those years. Partial payments were made from 1996 to 2000, as approved by the Board of Directors. The relevant clause was eliminated in 2001. The Tribunal Regional do Trabalho (“Regional Labour Court”) and the High Employment Court (“TST”) ordered Santander Brazil, as successor to Banespa, to pay this half-yearly bonus for the period from 1996 to the present. On 20 March 2019, the Supreme Federal Court (“STF”) rejected the extraordinary appeal filed by Santander Brazil. Santander Bank Brazil filed a rescissory action before the TST to nullify the decisions of the main proceedings. The rescissory action was dismissed and a motion for clarification was filed, due to the absence of an explicit argument to deny the rescissory action filed by Santander Brazil. After the decision of the motion for clarification, Santander Brazil filed an extraordinary appeal in the rescissory action in February 2021, which was denied in an interlocutory decision in June 2021 by the TST. As Santander Brazil understands there is a conflict between the TST decision and the doctrine set by the STF, Santander Brazil has appealed this decision. This appeal is pending. In August 2021, a first instance court has ruled that the enforcement of the TST decision shall be carried out individually, at the jurisdiction pertaining to each person. AFABESP appealed this decision. In December 2021, the Regional Labor Court denied the appeal filled by AFABESP. This decision has not been appealed by AFABESP, and therefore it has become final. Santander Brazil external advisers have classified the risk as probable. The recorded provisions are considered sufficient to cover the risks associated with the legal claims that are being substantiated as of 30 June 2022. • 'Planos Económicos': Like the rest of the banking system in Brazil, Santander Brazil has been the target of customer complaints and collective civil suits stemming mainly from legislative changes and its application to bank deposits ('economic plans'). At the end of 2017, an agreement between regulatory entities and the Brazilian Federation of Banks (“Febraban”) with the purpose of closing the lawsuits was reached and was approved by the Supremo Tribunal Federal. Discussions focused on specifying the amount to be paid to each affected client according to the balance in their notebook at the time of the Plan. Finally, the total value of the payments will depend on the number of adhesions there may be and the number of savers who have demonstrated the existence of the account and its balance on the date the indexes were changed. In November 2018, the STF ordered the suspension of all economic plan proceedings for two years from May 2018. On 29 May 2020, the STF approved the extension of the agreement for 5 additional years starting from 3 June 2020. Condition for this extension was to include in the agreement actions related to the “Collor I Plan”. The provision recorded for the economic plan proceedings amounts to EUR 262 million at 30 June 2022. • Floor clauses: as a consequence of the acquisition of Banco Popular Español, S.A., the Group has been exposed to a material number of transactions with floor clauses. The so-called "floor clauses" are those under which the borrower accepts a minimum interest rate to be paid to the lender, regardless of the applicable reference interest rate. Banco Popular Español, S.A. included "floor clauses" in certain asset-side transactions with customers. In relation to this type of clauses, and after several rulings made by the Court of Justice of the European Union and the Spanish Supreme Court, and the extrajudicial process established by the Spanish Royal Decree-Law 1/2017, of 20 January, Banco Popular Español, S.A. made provisions that were updated in order to cover the effect of the potential return of the excess interest charged for the application of the floor clauses between the contract date of the corresponding mortgage loans and May 2013. At 30 June 2022, after having processed most of the customer requests, the potential residual loss associated with ongoing court proceedings is estimated at EUR 44 million, amount which is fully covered by provisions. • Banco Popular´s acquisition: After the declaration of the resolution of Banco Popular Español, S.A. (“Banco Popular”), some investors filed claims against the EU’s Single Resolution Board decision, and the FROB's resolution executed in accordance to the aforementioned decision. Likewise, numerous appeals were filed against Banco Santander, S.A. alleging that the information provided by Banco Popular was erroneous and requesting from Banco Santander, S.A. the restitution of the price paid for the acquisition of the investment instruments or, where appropriate, the corresponding compensation. In relation to these appeals, on the one hand, the General Court of the European Union (“GCUE”) selected 5 appeals from among all those filed before the European courts by various investors against the European institutions and processed them as pilot cases. On 1 June 2022, the GCUE has rendered five judgements in which it has completely dismissed the appeals, (i) supporting the legality of the resolution framework applied to Banco Popular, (ii) confirming the legality of the action of the European institutions in the resolution of Banco Popular and (iii) rejecting, in particular, all the allegations that there were irregularities in the sale process of Banco Popular to Banco Santander, S.A. These judgements can be appealed before the Court of Justice of the European Union ('CJEU'). On the other hand, in relation to the lawsuits initiated by investors directly against Banco Santander, S.A. derived from the acquisition of Banco Popular, on 2 September 2020, the Provincial Court of La Coruña submitted a preliminary ruling to the CJEU in which it asked for the correct interpretation of the Article 60, section 2 of Directive 2014/59/EU of the European Parliament and of the Council, of May 15, 2014, establishing a framework for the restructuring and resolution of credit institutions and investment services companies. Said article establishes that, in the cases of redemption of capital instruments in a bank resolution, no liability will subsist in relation to the amount of the instrument that has been redeemed. On 5 May 2022, the CJEU has rendered its judgement confirming that Directive 2014/59/EU of the European Parliament and of the Council does not allow that, after the total redemption of the shares of the share capital of a credit institution or an investment services company subject to a resolution procedure, the shareholders who have acquired shares within the framework of a public subscription offer issued by said company before the start of such a resolution procedure, exercise against that entity or against its successor, an action for liability for the information contained in the prospectus, under Directive 2003/71/EC of the European Parliament and of the Council, or an action for annulment of the subscription contract for those shares, which, taking into account its retroactive effects, gives rise to the restitution of the equivalent value of said shares, plus the interest accrued from the date of execution of said contract. Separately, the Central Court of Instruction 4 is currently conducting preliminary proceedings 42/2017, in which, amongst other things, is being investigated the following: (i) the accuracy of the prospectus for the capital increase with subscription rights carried out by Banco Popular in 2016; and (ii) the alleged manipulation of the share price of Banco Popular until the resolution of the bank, in June 2017. During the course of the proceedings, on 30 April 2019, the Spanish National Court, ruled in favour of Banco Santander, S.A. declaring that Banco Santander, S.A. cannot inherit Banco Popular’s potential criminal liability. This ruling was appealed before the Supreme Court, which rejected it. In these proceedings, Banco Santander, S.A. could potentially be subsidiarily liable for the civil consequences. Recently, and in view of the CJEU ruling of 5 May 2022, the Bank has requested confirmation of the exclusion of its subsidiary civil liability status in this criminal proceeding. On 26 July 2022, the Court has rejected this request stating that it is a matter to be determined at a later procedural time. This decision is subject to appeal. The estimated cost of any compensation to shareholders and bondholders of Banco Popular recognized in the 2017 accounts amounted to EUR 680 million, of which EUR 535 million were applied to the commercial loyalty program. The CJEU judgement of 5 May represents a very significant reduction in the risk associated with these claims. • German shares investigation: The Cologne Public Prosecution Office is conducting an investigation against the Bank, and other group entities based in the UK - Santander UK plc, Santander Financial Services Plc and Cater Allen International Limited -, in relation to a particular type of tax dividend linked transactions known as cum-ex transactions. The Group is cooperating with the German authorities. According to the state of the investigations, the result and the effects for the Group, which may potentially include the imposition of material financial penalties, cannot be anticipated. For this reason, the Bank has not recognized any provisions in relation to the potential imposition of financial penalties. • Banco Santander, S.A. has been sued in a legal proceeding in which the plaintiff alleges that a contract was concluded whereby he would be entrusted with the functions of CEO of the Bank. In the complaint, the claimant mainly requests a declaratory ruling that affirms the validity and conclusion of such contract and its enforcement together with the payment of certain amounts. If the main request is not granted, the claimant sought a compensation for a total amount of approximately EUR 112 million or, an alternative relief for other minor amounts. Banco Santander, S.A. answered to the complaint stating that the conditions to which the appointment was subject to were not met and that the contract required by law was not concluded. On 17 May 2021, the plaintiff reduced his claims for compensation to EUR 61.9 million. On 9 December 2021, the Court has rendered its decision ordering the Bank to compensate the plaintiff in the amount of EUR 67.8 million. On 13 January 2022, the Court has corrected and supplemented its judgment, reducing the total amount to EUR 51.4 million and establishing that part of this amount (EUR 18.6 million) would have to be paid in shares of Banco Santander, S.A. and subject to the application of the same terms provided in the applicable Santander executives’ remuneration program (deferred and linked to Santander’s performance metrics). On 14 February 2022, the Bank filed an appeal against the judgment before the Provincial Court of Madrid, which was formally objected by the plaintiff on 7 March 2022. The decision is pending. In parallel, the plaintiff lodged a request for provisional partial enforcement of the judgment of first instance. An order was issued for execution and the Bank deposited the entire amount within the voluntary compliance period. If the appeal filed by the Bank succeeds, the amount would be returned with the applicable interest. The provisions recorded are considered to be sufficient to cover the risks deriving from this claim. • Universalpay Entidad de Pago, S.L. has filed a lawsuit against Banco Santander, S.A. for breach of the marketing alliance agreement (“MAA”) and claim payment (EUR 1,050 million). The claim is being processed in the Court of First Instance no. 81 of Madrid. The MAA was originally entered into by Banco Popular Español, S.A. and its purpose is the rendering of acquiring services (point of sale payment terminals) for businesses in the Spanish market. The lawsuit is mainly based on the potential breach of clause 6 of the MAA, which establishes certain obligations of exclusivity, non-competition and customer referral. The Bank answered the complaint on May 2021 and the pretrial hearing took place on 11 March 2022. The hearing of the case will take place on 10 and 11 November 2022. At the current stage of the proceeding, there are still factual issues pending resolution, which may have legal consequences and affect any potential liability. This uncertainty makes it impossible to reliably predict the resolution of the issue, the timing or the significance of the potential economic impact. • CHF Polish Mortgage Loans. On 3 October 2019, the Court of Justice of the European Union (“CJEU”) rendered its decision in relation to a judicial proceeding against an unrelated bank in Poland considering that certain contractual clauses in CHF-indexed loan agreements were abusive. The CJEU has left to Polish courts the decision on whether the whole contract can be maintained once the abusive terms have been removed, which should in turn decide whether the effects of the annulment of the contract are prejudicial to the consumer. In case of maintenance of the contract, the court may only integrate the contract with subsidiary provisions of national law and decide, in accordance with those provisions, on the applicable rate. In 2021, the Supreme Court was expected to take a position regarding the key issues in disputes concerning loans based on foreign currency, clarifying the discrepancies and unifying case law. The Supreme Court met several times, with the last session taking place on 2 September 2021. However, the resolution was not adopted and instead, the Supreme Court referred questions to the CJEU on constitutional issues of the Polish judiciary system. No new date for consideration of the issue has been set and no comprehensive decision by the Supreme Court of the issue is expected in the near future. In the absence of a comprehensive position of the Supreme Court, it is difficult to expect a full unification of judicial decisions, and decisions of the Supreme Court and CJEU issued on particular issues may be important for shaping further case law on CHF matters. At the date of these interim financial statements, there is no uniform ruling practice and – in the opinion of Santander Bank Polska and Santander Consumer Bank Poland - it is not possible to predict the Supreme Court’s and CJEU decisions on individual cases. Santander Bank Polska and Santander Consumer Bank Poland regularly monitor court rulings on foreign currency loans to verify changes in case law practice. As of 30 June 2022, Santander Bank Polska and Santander Consumer Bank Poland maintain a portfolio of mortgages denominated in or indexed to CHF for an approximate gross amount of PLN 9,119.9 million (EUR 1,940 million). As of 1 January 2022, in accordance with IFRS 9 and based on the new best available information, the gross carrying amount of mortgage loans denominated and indexed in foreign currencies is reduced by the amount in which the estimated cash flows are not expected to cover the gross amount of loans, including as a result of legal controversies relating to these loans. In the absence of exposure or insufficient gross exposure, a provision according to IAS 37 is recorded. Total value of adjustment to gross carrying amount in accordance with IFRS9 as well as provisions recorded under IAS37, amount to PLN 2,964.5 million (EUR 630.5 million) of which PLN 2,651.1 million (EUR 563.9 million) corresponds to adjustment to gross carrying amount under IFRS 9 and PLN 313.3 million (EUR 66.6 million) to provisions recognized in

Equity [abstract]
Equity	Equity In the first six month periods ended 30 June 2022 and 2021 there were no quantitative or qualitative changes in Grupo Santander's equity other than those indicated in the condensed consolidated statements of changes in total equity. a) Capital Banco Santander's share capital at 30 June 2022 and 31 December 2021 consisted of EUR 8,397 and EUR 8,670 million, respectively, represented by 16,794,401,584 and 17,340,641,302 shares of EUR 0.50 of nominal value each, respectively, and all of them of a unique class and series. On 1 April 2022, there was a capital reduction amounting to EUR 129,965,136.50 through the redemption of 259,930,273 shares, corresponding to the share buyback program carried out in 2021. Likewise, on 28 June 2022, Banco Santander has decreased its capital by an amount of EUR 143,154,722.50 through the redemption of 286,309,445 shares, corresponding to the share buyback program carried out during the first half of 2022. Both operations have not entailed the return of contributions to the shareholders as Banco Santander was the owner of the redeemed shares. b) Share premium Includes the amount paid by the bank's shareholders in capital issues in excess of par value. As a result of the capital reductions described in Note 11.a, the issue premium has been reduced during the first half of 2022 by an amount of EUR 1,433 million, corresponding to the difference between the purchase value of the redeemed shares (EUR 1,706 million) and the par value of said shares (EUR 273 million). Likewise, in accordance with the applicable legislation, a reserve has been provided for amortized capital charged to the issue premium for an amount equal to the nominal value of said amortized shares (EUR 273 million). The decrease produced in 2021 for an amount of EUR 4,034 milli on has been the consequence of applying the result obtained by Banco Santander during the financial year 2020, consisting of losses of EUR 3,557 million and the charge of the dividend for the fiscal year 2020 for an amount of EUR 477 million, as reflected in the interim consolidated statement of changes in total equity. c) Breakdown of other comprehensive income - Items not reclassified to profit or loss and Items that may be reclassified to profit or loss EUR million 30-06-2022 31-12-2021 Other comprehensive income accumulated (32,526) (32,719) Items not reclassified to profit or loss (3,809) (4,241) Actuarial gains or losses on defined benefit pension plans (3,284) (3,986) Non-current assets held for sale — — Share in other income and expenses recognised in investments, joint ventures and associates (9) (8) Other valuation adjustments — — Changes in the fair value of equity instruments measured at fair value with changes in other comprehensive income (512) (157) Inefficacy of fair value hedges of equity instruments measured at fair value with changes — — Changes in the fair value of equity instruments measured at fair value with changes 312 275 Changes in the fair value of equity instruments measured at fair value with changes (312) (275) Changes in the fair value of financial liabilities measured at fair value through profit or loss (4) (90) Items that may be reclassified to profit or loss (28,717) (28,478) Hedge of net investments in foreign operations (effective portion) (5,976) (4,283) Exchange differences (19,524) (23,887) Hedging derivatives (effective portion) (2,054) (276) Changes in the fair value of debt instruments measured at fair value with changes in other comprehensive income (834) 436 Hedging instruments (items not designated) — — Non-current assets held for sale — — Share in other income and expenses recognised in investments, joint ventures and associates (329) (468) d) Other comprehensive income - Items not reclassified to profit or loss - Actuarial gains or losses on defined benefit pension plans The changes in the balance of Other comprehensive income - Items not reclassified to profit or loss - Actuarial gains or losses on defined benefit pension plans include the actuarial gains or losses generated in the period and the return on plan assets, excluding amounts included in net interest on the net defined benefit liability (asset), less the administrative expenses and taxes inherent to the plan, and any change in the effect of the asset ceiling. Its variation is shown in the condensed consolidated statement of recognised income and expense. During the first six months of 2022, the amoun t of actuarial losses (net of actuarial gains) has decreased by EUR 843 million. T he main impacts are: • Decrease of EUR 386 million in the cumulative actuarial losses relating to the Group´s businesses in the UK, mainly due to the evolution experienced by the discount rate (increase from 1.90% to 3.84%), partly compensated by the movement of assets. • Decrease of EUR 229 million in the accumulates actuarial losses relating to the Group´s entities in Spain, mainly due to the discount rate variation (increase from 0.90% to 3.10%). • Decrease of EUR 161 million in the cumulative actuarial losses relating to the Group's businesses in Germany, due to the discount rate variation (increase from 1.45% to 3.55%). • Decrease of EUR 110 million in the cumulative actuarial losses relating to the Group's businesses in Portugal, due to the discount rate variation (increase from 1.10% to 2.60%). • Decrease of EUR 46 million in accumulated actuarial losses corresponding to the Group’s business in Brazil, mainly due to the increase in the discount rate (increase from 8.39% to 9.12% for pension plans), partly compensated by the movement of assets. The other modification in accumulated actuarial profit or losses is an increase of EUR 89 million as a result of the evolution of exchange rates, mainly the appreciation of the Brazilian real. e) Other comprehensive income - Items not reclassified to profit or loss – Changes in the fair value of equity instruments measured at fair value with changes in other comprehensive income Includes the net amount of unrealised fair value changes in equity instruments at fair value with changes in other comprehensive income. Below is a breakdown of the composition of the balance as of 30 June 2022 and 31 December 2021 under 'Other comprehensive income - Items not reclassified to profit or loss - Changes in the fair value of equity instruments measured at fair value with changes in other comprehensive income' depending on the geographical origin of the issuer: EUR million 30-06-2022 31-12-2021 Revaluation gains Revaluation losses Net revaluation gains/(losses) Fair value Revaluation gains Revaluation losses Net revaluation gains/(losses) Fair value Equity instruments Domestic Spain 25 (916) (891) 504 25 (663) (638) 759 International Rest of Europe 82 (59) 23 220 39 (58) (19) 170 United States 17 (5) 12 36 13 (4) 9 31 Latin America and rest 346 (2) 344 1,371 496 (5) 491 1,493 470 (982) (512) 2,131 573 (730) (157) 2,453 Of which: Listed 346 (46) 300 1,391 500 (44) 456 1,521 Unlisted 124 (936) (812) 740 73 (686) (613) 932 f) Other comprehensive income - Items that may be reclassified to profit or loss – Hedges of net investments in foreign operations (effective portion) and exchange differences Other comprehensive income - Items that may be reclassified to profit or loss - Hedges of net investments in foreign operations (effective portion) includes the net amount of the changes in value of hedging instruments in hedges of net investments in foreign operations, in respect of the portion of these changes considered to be effective hedges. Other comprehensive income - Items that may be reclassified to profit or loss - Exchange differences includes the net amount of exchange differences arising on non-monetary items whose fair value is adjusted against equity and the differences arising on the translation to euros of the balances of the consolidated entities whose functional currency is not the euro. The net variation of both headings recognised during the first six months of 2022 in the interim condensed consolidated statement of recognised income and expenses, reflects the impact of the evolution of the currencies during the year, reflecting mainly the strong appreciation of the Brazilian real, US dollar and Mexican peso, and in the negative side the impact of the depreciation of the Pound sterling (see Note 1.e). Of this variation, a capital gain of EUR 643 million corresponds to the valuation at the closing exchange rate of goodwill for the first six months of 2022 (see Note 8). g) Other comprehensive income – Items that may be reclassified to profit or loss – Changes in the fair value of debt instrument s measured at fair value through other comprehensive income Includes the net amount of unrealised fair value changes in debt instruments at fair value through other comprehensive income.

Due to this fact Debt securities were transferred from the 'Financial asset at fair value through other comprehensive income' to the ‘Financial asset at amortised cost', being the value of these assets at the date of the transfer EUR 6,427 million.

Segment information (Primary se

Segment information (Primary segment)	6 Months Ended

Disclosure of operating segments [abstract]
Segment information (Primary segment)	Segment information (Primary segment) Grupo Santander has aligned the information in this note with the underlying information used internally for management reporting and with that presented in Grupo Santander's other public documents. Grupo Santander's executive committee has been selected to be its chief operating decision maker. Grupo Santander's operating segments reflect its organizational and managerial structures. The executive committee reviews internal reporting based on these segments to assess performance and allocate resources. The segments are split by geographic area in which profits are earned and type of business. We prepare the information by aggregating the figures for Santander’s various geographic areas and business units, relating it to both the accounting data of the units integrated in each segment and that provided by management information systems. The same general principles as those used in Grupo Santander are applied. On 4 April 2022, Grupo Santander announced that, starting and effective with the financial information for the first quarter of 2022, it will carry out changes in the reportable segments to reflect the new reporting structure. The main changes, which have been applied to management information for all periods included in the interim financial statements, relate to the allocation of certain financial costs of the Corporate Centre as follows: • Further clarity in the minimum requirement for own funds and eligible liabilities (MREL) and total loss absorbing capacity (TLAC) regulation makes it possible to allocate the cost of eligible debt issuances to the corresponding units from the Corporate Centre. • Other financial costs, primarily associated with the cost of funding the excess capital held by the units above the Group's CET1 ratio have been reassigned from the Corporate Centre to the corresponding units. Following is the breakdown of revenue that is deemed to be recognised under Dividend income, Commission income, Gain or losses on financial assets and liabilities not measured at fair value through profit or loss, net, Gain or losses on financial assets and liabilities held for trading, net, Gain or losses on non-trading financial assets and liabilities mandatorily at fair value through profit or loss, Gain or losses on financial assets and liabilities measured at fair value through profit or loss, net, Gain or losses from hedge accounting, net, Other operating income and Income from assets under insurance and reinsurance contracts in the accompanying consolidated income statements for the first six months ended 30 June 2022 and 2021. In addition to these operating units, which report by geographic area and businesses, Grupo Santander continues to maintain the area of Corporate Centre, that includes the centralized activities relating to equity stakes in financial companies, financial management of the structural exchange rate position, assumed within the sphere of Grupo Santander's assets and liabilities committee, as well as management of liquidity and of shareholders' equity via issuances. This financial information ('underlying basis') is computed by adjusting reported results for the effects of certain gains and losses (e.g.: capital gains, write-downs, etc.). These gains and losses are items that management and investors ordinarily identify and consider separately to understand better the underlying trends in the business. Following is the reconciliation between the adjusted profit and the statutory profit corresponding to the first six months ended 30 June 2022 and 2021: EUR million Revenue from ordinary activities Profit before taxes Profit Segment 30-06-2022 30-06-2021 30-06-2022 30-06-2021 30-06-2022 30-06-2021 Europe 13,649 10,862 2,693 1,963 1,839 1,312 North America 8,154 7,315 2,061 2,478 1,578 1,581 South America 17,613 10,580 3,165 3,105 1,946 1,639 Digital Consumer Bank 3,395 3,245 1,010 888 572 485 Corporate Centre 173 (169) (1,014) (805) (1,041) (812) Underlying Profit 42,984 31,833 7,915 7,629 4,894 4,205 Adjustments — — — (715) — (530) Statutory Profit 42,984 31,833 7,915 6,914 4,894 3,675 Explanation of adjustments: In the first six months of 2021, the impact of restructuring costs of EUR -530 million was mainly in the United Kingdom and Portugal.

In cases where price quotations cannot be observed, management makes its best estimate of the price that the market would set, using its own internal models. In most cases, these internal models use data based on observable market parameters as significant inputs (level 2) and, in cases, they use significant inputs not observable in market data (level 3). In order to make these estimates, various techniques are employed, including the extrapolation of observable market data. The best evidence of the fair value of a financial instrument on initial recognition is the transaction price, unless the fair value of the instrument can be obtained from other market transactions performed with the same or similar instruments or can be measured by using a valuation technique in which the variables used include only observable market data, mainly interest rates. During the first six months of 2022 and 2021, Grupo Santander did not make any material transfers of financial instruments between measurement levels other than the transfers included in level 3 table. Grupo Santander has developed a formal process for the systematic valuation and management of financial instruments, which has been implemented worldwide across all the Group’s units. The governance scheme for this process distributes responsibilities between two independent divisions: Treasury (development, marketing and daily management of financial products and market data) and Risk (on a periodic basis, validation of pricing models and market data, computation of risk metrics, new transaction approval policies, management of market risk and implementation of fair value adjustment policies). The approval of new products follows a sequence of steps (request, development, validation, integration in corporate systems and quality assurance) before the product is brought into production. This process ensures that pricing systems have been properly reviewed and are stable before they are used. The most important products and families of derivatives, and the related valuation techniques and inputs, by asset class, are detailed in the consolidated annual accounts as at 31 December 2021. As of 30 June 2022, the CVA (Credit Valuation Adjustment) accounted for was EUR 308 million (an increase of 30% compared to 31 December 2021) and adjustments of DVA (Debt Valuation Adjustment) was EUR 280 million (an increase of 73% compared to 31 December 2021). The increase is mainly due to movements in the credit markets, whose spread levels have doubled compared to those at the end of the year. These increases have been partially offset by reductions in exposures due to the increase in the medium and long-term yield curves. Set forth below are the financial instruments at fair value whose measurement was based on internal models (levels 2 and 3) at 30 June 2022 and 31 December 2021: EUR million EUR million Fair values

the market, while level 3 internal models uses significant inputs that are not observable in market data. (**) Includes mainly short-term loans/deposits and repurchase/reverse repurchase agreements with corporate customers (mainly brokerage and investment companies). (***) Includes mainly structured loans to corporate clients. Level 3 financial instruments Set forth below are the Group’s main financial instruments measured using unobservable market data as significant inputs of the internal models (level 3): • HTC&S (Hold to collect and sale) syndicated loans classified in the fair value category with changes in other comprehensive income, where the cost of liquidity is not directly observable in the market, as well as the prepayment option in favour of the borrower. • Illiquid equity in non-trading portfolios, classified at fair value through profit or loss and at fair value through equity. • Instruments in Santander UK’s portfolio (loans, debt instruments and derivatives) linked to the House Price Index (HPI). Even if the valuation techniques used for these instruments may be the same as those used to value similar products (present value in the case of loans and debt instruments, and the Black-Scholes model for derivatives), the main factors used in the valuation of these instruments are the HPI spot rate, the growth and volatility thereof, and the mortality rates, which are not always observable in the market and, accordingly, these instruments are considered illiquid. • Callable interest rate derivatives (Bermudan-style options) where the main unobservable input is mean reversion of interest rates. • Trading derivatives on interest rates, taking as an underlying asset titling and with the amortization rate (CPR, Conditional prepayment rate) as unobservable main entry. • Derivatives from trading on inflation in Spain, where volatility is not observable in the market. • Equity volatility derivatives, specifically indices and equities, where volatility is not observable in the long term. • Derivatives on long-term interest rate and FX in some units (mainly South America) where for certain underlyings it is not possible to demonstrate observability to these terms. • Debt instruments referenced to certain illiquid interest rates, for which there is no reasonable market observability. The measurements obtained using the internal models might have been different if other methods or assumptions had been used with respect to interest rate risk, to credit risk, market risk and foreign currency risk spreads, or to their related correlations and volatilities. Nevertheless, the Bank’s directors consider that the fair value of the financial assets and liabilities recognised in the interim condensed consolidated balance sheet and the gains and losses arising from these financial instruments are reasonable. The net amount recorded in the results of the first six months of 2022 arising from models whose significant inputs are unobservable market data (level 3) amounted to EUR 19 million profit (EUR 11 million loss in the first six months of 2021). The table below shows the effect, at 30 June 2022 and 31 December 2021, on the fair value of the main financial instruments classified as Level 3 of a reasonable change in the assumptions used in the valuation. This effect was determined by applying the probable valuation ranges of the main unobservable inputs detailed in the following table: 2022 Portfolio/Instrument Valuation technique Main unobservable inputs Range 1 Weighted average Impacts (EUR million) (Level 3) Unfavourable scenario Favourable scenario Financial assets held for trading Derivatives CCS Discounted Cash Flows Interest rate (0.7)% - 0.7% 0.73% (0.09) 0.09 CCS Forward estimation Interest rate (4)pb - 4pb 4.00% (0.14) 0.11 EQ Options EQ option pricing model Volatility 0% - 90% 61.30% (0.24) 0.50 EQ Options Local volatility Volatility 10% - 90% 40.00% (3.53) 3.53 FRAs Asset Swap model Interest rate 0% - 4% 1.81% (0.77) 0.64 FX Options FX option pricing model Volatility 0% - 50% 31.37% (0.23) 0.39 Inflation Derivatives Asset Swap model Inflation Swap Rate (50)% - 50% 50.00% (0.43) 0.22 Inflation Derivatives Volatility option model Volatility 0% - 40% 14.04% (0.35) 0.19 IR Futures Asset Swap model Interest rate 0% - 15% 6.02% (0.84) 0.57 IR Options IR option pricing model Volatility 0% - 60% 35.82% (0.15) 0.22 IRS Asset Swap model Interest rate (5.9)% - 12.7% 10.27% (0.06) 0.11 IRS Discounted Cash Flows Credit spread 154.5% - 632.3% 156.06% (3.82) 2.49 IRS Discounted Cash Flows Swap Rate 9% - 9.4% 9.28% 0.00 0.00 IRS Forward estimation Interest rate (8.95) TIIE 91pb - 15.18 TIIE 91pb n.a.

Introduction, basis of presen_2

Introduction, basis of presentation of the interim condensed consolidated financial statements and other information (Policies)	6 Months Ended
	Jun. 30, 2022
Disclosure of reclassifications or changes in presentation [abstract]
Basis of presentation of the interim financial statements	Basis of presentation of the interim financial statements Under Regulation (EC) n.º 1606/2002 of the European Parliament and of the Council of 19 July 2002 all companies governed by the law of an EU Member State and whose securities are admitted to trading on a regulated market of any Member State must prepare their consolidated financial statements for the years beginning on or after 1 January, 2005 in conformity with the International Financial Reporting Standards ('IFRS') previously adopted by the European Union ('EU-IFRS'). In order to adapt the accounting system of Spanish credit institutions with the principles and criteria established by the IFRS adopted by the European Union ('EU-IFRS'), the Bank of Spain published circular 4/2017, dated 27 November 2017, and subsequent changes, on Public and Confidential Financial Reporting Standards and Financial Statement Formats. The consolidated annual accounts for 2021 were authorised at the board of directors meeting on 24 February 2022 in compliance with International Financial Reporting Standards as adopted by the European Union, taking into account Bank of Spain Circular 4/2017, and subsequent modifications, using the basis of consolidation, accounting policies and measurement bases described in Note 2 to the aforementioned consolidated annual accounts and, accordingly, they presented fairly Grupo Santander’s consolidated equity and consolidated financial position at 31 December 2021 and the consolidated results of its operations, and the consolidated cash flows in 2021. The aforementioned consolidated annual accounts, which are included in Grupo Santander’s Form 6-K filed with the U.S. Securities and Exchange Commission on 8 April 2022, and these interim financial statements are also in compliance with International Financial Reporting Standards as issued by the International Accounting Standards Board ('IFRS-IASB', and together with EU-IFRS, 'IFRS'). These interim financial statements were prepared and are presented in accordance with International Accounting Standard (IAS 34), Interim Financial Reporting, for the preparation of interim financial statements in accordance with the provisions of article 12 of Royal Decree 1362 /2007 and taking into account the requirements of Circular 3/2018, of 28 June, of the Spanish National Securities Market Commission ('CNMV'). The aforementioned interim financial statements will be included in the half-year financial report for the first six months of 2022 to be presented by the Group in accordance with the Circular 3/2018. In accordance with IAS 34, the interim financial statements are intended only to provide an update on the content of the latest consolidated annual accounts authorised for issue, focusing on new activities, events and circumstances occurring during the first six months, and does not duplicate information previously reported in the latest consolidated annual accounts. Consequently, these interim financial statements do not include all the information that would be required for a complete set of consolidated annual accounts prepared in accordance with IFRS and, accordingly, for a proper comprehension of the information included in these interim financial statements, they should be read together with Grupo Santander’s consolidated annual accounts for the year ended 31 December 2021. Grupo Santander policies include presenting the interim financial statements for its use in the different markets using the Euro as its presentation currency. The amounts held in other currencies and the balances of entities whose functional currency is not the Euro, have been translated to the presentation currency in accordance with the criteria indicated in Note 2.a to the consolidated annual accounts for 2021. As indicated in that Note, for practical reasons, the balance sheet amount has been converted to the closing exchange rate, the equity to the historical type, and the income and expenses have been converted by applying the average exchange rate of the period; the application of such exchange rate or that corresponding to the date of each transaction does not lead to significant differences in the interim financial statements of Grupo Santander. The accounting policies and methods used in preparing these interim financial statements are the same as those applied in the consolidated annual accounts for 2021 taking into account the standards and interpretations with effective application date during the first six months of 2022, which are detailed below: – Amendment to IFRS 3 Business Combinations: to update the references to the Conceptual Framework for Financial Reporting and add an exception for the recognition of liabilities and contingent liabilities within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets and IFRIC 21 Levies. The amendments also confirm that an acquirer should not recognize contingent assets acquired in a business combination. Applicable from 1 January 2022. – Amendment to IAS 16 Property, Plant and Equipment: prevents an entity from deducting from the cost of an item of property, plant and equipment any revenue from the sale of finished goods while the entity is preparing the item for its intended use. It is also clear that an entity is "testing whether the asset is functioning properly" when evaluating the technical and physical performance of the asset. The financial performance of the asset should not be taken into account for this evaluation. Additionally, entities should disclose separately the amounts of income and expenses related to finished goods that are not the product of the entity's ordinary activities. Applicable from 1 January 2022. – Amendment to IAS 37 Provisions, Contingent Liabilities and Contingent Assets: clarifies that the direct costs of fulfilling a contract include both the incremental costs of fulfilling the contract and an allocation of other costs directly related to fulfilling contracts. Before recognising a separate provision for an onerous contract, the entity recognises any impairment loss that has occurred on assets used in fulfilling the contract. Applicable from 1 January 2022. – Amendment to IFRS Cycle (2018-2020): introduces minor amendments, applicable from 1 January 2022, to the following standards: • IFRS 9 Financial Instruments: clarifies which rates must be included in the 10% test for derecognition of financial liabilities. • IFRS 16 Leases: amendment to remove possible confusion regarding the treatment of leasing incentives in the application of IFRS 16 Leases. • IFRS 1, in relation to the first-time adoption of International Financial Reporting Standards, allows entities that have measured their assets and liabilities at the carrying amounts recorded in their parent's books to also measure any cumulative translation differences using the amounts reported by the parent. This amendment also applies to associates and joint ventures that have adopted the same exemption from IFRS 1. The aforementioned amendments to accounting standards have not had a significant effect on Grupo Santander’s financial statements. All accounting policies and measurement bases with a material effect on the interim financial statements for 30 June 2022 were applied in their preparation.
Use of critical estimates	Use of critical estimates The consolidated results and the determination of the consolidated equity are sensitive to the accounting principles and policies, valuation criteria and estimates used by the directors of Banco Santander in preparing the interim financial statements. The main accounting principles, policies, and valuation criteria are indicated in note 2 of the consolidated annual accounts of the year 2021, except for those indicated in these interim financial statements due to the rules that have come into effect during the first six months of the year 2022. The interim financial statements contain estimates made by the senior management of Banco Santander and of the consolidated entities in order to quantify certain of the assets, liabilities, income, expenses and obligations reported in the consolidated entities. These estimates, which were made on the basis of the best information available, relate mainly to the following: 1. The income tax expense, which, in accordance with IAS 34, is recognised in interim periods based on the best estimate of the weighted average tax rate expected by Grupo Santander for the full financial year; 2. The impairment losses on certain assets – Financial assets at fair value through other comprehensive income, financial assets at amortised cost, non-current assets held for sale, investments in subsidiaries, joint ventures and associates, tangible assets and intangible assets; 3. The assumptions used in the calculation of the post-employment benefit liabilities and commitments and other obligations; 4. The useful life of the tangible and intangible assets; 5. The measurement of goodwill impairment arising on consolidation; 6. The calculation of provisions and the consideration of contingent liabilities; 7. The fair value of certain unquoted assets and liabilities; 8. The recoverability of deferred tax assets; and 9. The fair value of the identifiable assets acquired and the liabilities assumed in business combinations in accordance with IFRS 3. To update the above estimates, the Group's management has considered the situation of the war in Ukraine. The Group has no presence in Russia or Ukraine and its direct exposure to Russian and Ukrainian markets and assets are not material. The extent to which the conflict could ultimately impact the Group's results will depend on future developments, including subsequent sanctions that could eventually affect negatively to some Groups’ customers (those more closely related to Russia or Ukraine). Group's management has assessed the uncertainties caused by the current situation (high inflation, rise in interest rates, supply chain disruptions in more sensitive sectors, etc.) taking into account the best information available in order to anticipate the impact on the most relevant portfolios. Furthermore, Grupo Santander reinforced the monitoring of all risks, with special attention to Poland (due to its geographical situation). Overall, the most significant impacts have been in higher commodity prices, particularly energy, and lower household disposable income due to inflationary pressures. The main actions being taken by Santander have been: • Identification of potentially affected customers, specially by the increase in energy and oil prices, leveraging on risk playbooks • Cyber teams prepared for a possible contingency, as cyber threats have increased due to the conflict. • Sensitivity analysis to assess potential impacts and define action plans if needed. • Continuous revision, by the Compliance teams, of the correct application of the sanctions established by the international community. • Activation of the Special Situation Committee to oversee the potential effects of the conflict. In addition, the Group's Management has taken into account the current situation as a result of covid-19, which significantly affected the economic activity worldwide and, as a result, the Group's operations and financial results. In order to minimize the medium- and long-term economic impacts of the efforts made to contain the covid-19 pandemic, in 2020 and 2021, governments and economic and regulatory authorities of the main countries, in which the Group operates, launched a set of fiscal and monetary policy measures and other initiatives to mitigate the impact of the pandemic on the economy and to support companies and people. Likewise, Grupo Santander implemented a set of customer relief measures in full compliance with regulatory and supervisory recommendations. Santander continued to support its customers in the first six months of 2022, fostering their economic resilience in all the Group's geographies. In relation to the relief measures to tackle the pandemic effects, the Group’s total moratoria programmes granted have fully expired at the end of first half performing better than expected. Regarding government liquidity programmes, the Group is closely monitoring their performance as the grace periods established are reaching their end. Spain concentrates most of these types of programmes, with 87% of the grace periods expired and credit quality in line with expectations, with no concerning signs of deterioration. Lastly, the Group has partially and voluntarily aligned during the first half of 2022 the accounting definition of stage 3, as well as for the calculation of impairment provision models, to the New Definition of Default, incorporating the criteria defined by the EBA in its implementation guide of the definition of default, capturing the economic deterioration of the operations (days in default - on a daily basis – and materiality thresholds - minimum amount in arrears). The alignment of criteria has been done taking into account the criteria of IFRS 9 as well as the accounting principles of unbiased presentation of financial information. There has been an increase in the default rate at around 19 basis points, with no material impact on the provision figures for credit risk. During the first six months ended 30 June 2022, there have been no additional significant changes in the estimates made at the end of 2021, other than those indicated in these interim financial statements.
Contingent assets and liabilities	Contingent assets and liabilitiesNote 2.o to Grupo Santander's consolidated annual accounts for the year ended 31 December 2021 includes information on the contingent assets and liabilities at that date. There were no significant changes in Grupo Santander's contingent assets and liabilities from 31 December 2021 to the date of formal preparation of these interim financial statements.
