**Banco Santander, S.A. and Companies composing Grupo Santander**

Explanatory notes to the interim condensed consolidated financial statements for the nine-month period ended 30 September 2025.

**<u>1.&nbsp;&nbsp;&nbsp;&nbsp;Introduction, basis of presentation of the interim condensed consolidated financial statements and other information</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***a)&nbsp;&nbsp;&nbsp;&nbsp;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 nine-month period ended 30 September 2025 were authorised and approved by Grupo Santander's directors at the board of directors meeting held on 28 October 2025. Grupo Santander's consolidated annual accounts for year 2024 were approved by shareholders at Banco Santander annual general meeting on 4 April 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***b)&nbsp;&nbsp;&nbsp;&nbsp;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 2024 were authorised at the board of directors meeting on 25 February 2025 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 2024 and the consolidated results of its operations, and the consolidated cash flows in 2024. The aforementioned consolidated annual accounts, which are included in Grupo Santander's Form 20-F filed with the U.S. Securities and Exchange Commission on 28 February 2025, 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 and contains disclosures relating to the first nine months of 2025.

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 2024.

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 2024, except for the exchange rate used for the Argentine peso (see Note 1.c). 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 2024 including the following accounting standard with an effective application date 1 January 2025, which is detailed below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amendment to IAS 21 Effects of changes in foreign currency exchange rates: IAS 21 established the requirements to apply when there is a temporary lack of interchangeability between two currencies, but did not give indications when this situation was not temporary. Given this scenario, IAS 21 has been modified establishing the criteria to identify these situations, specifying how entities should estimate the spot exchange rate, the methodologies and data to be considered, as well as the associated disclosure requirements. Group applied the aforementioned amendment in advance as of 31 December 2024; for more information see Note 1.c.

The aforementioned accounting standards and modifications have not had a significant effect on Grupo Santander's financial statements, except for what was disclosed before.

All accounting policies and measurement bases with a material effect on the interim financial statements for 30 September 2025 were applied in their preparation.

By the time of the preparation of these interim financial statements, there are no standards pending adoption by the European Union for the current exercise by the IASB with an effective date of 1 January 2025.

&nbsp;&nbsp;&nbsp;&nbsp;***c)&nbsp;&nbsp;&nbsp;&nbsp; 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 2024, except for those indicated in these interim financial statements due to the accounting standards and modifications that have come into effect during the first nine months of the year 2025.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The income tax expense, which 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The assumptions used in the calculation of the post-employment benefit liabilities and commitments and other obligations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The useful life of the tangible and intangible assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The measurement of goodwill impairment arising on consolidation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The calculation of provisions and the consideration of contingent liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The fair value of certain unquoted assets and liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The recoverability of deferred tax assets; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The fair value of the identifiable assets acquired and the liabilities assumed in business combinations in accordance with IFRS 3.

To update the previous estimates, the Group's management has taken into account the current macroeconomic scenario resulting from the complex geopolitical situation and the changes in inflation levels, interest rates and currency exchange rate trends, albeit with a resilient labor market in the geographies where the Group operates.

The Group's management has evaluated in particular the uncertainties caused by the current environment in relation to credit risk, maintaining active oversight of clients in geographies and sectors more exposed to international trade tensions, global geopolitical uncertainty and the impact of public debt containment policies or fiscal stimulus measures, liquidity and market risks, taking into account the best available information, to estimate the impact on the credit portfolio's impairment provision, and in the debt instruments' interest rates and valuation.

In the second quarter of 2024, as a result of the significant divergence between the official exchange rate and other macroeconomic factors, primarily inflation, Grupo Santander began applying an alternative exchange rate to the official exchange rate for the Argentine peso. This rate reflects the exchange rate observed in orderly transactions between market participants under prevailing economic conditions for certain purposes, such as the repatriation of dividends from businesses in Argentine.

Given the stabilization and improvement in the country's macroeconomic outlook, during the fourth quarter of 2024 and the first quarter of 2025, this alternative rate was based on the CCL dollar ('*contado con liquidación*'), which is the exchange rate that results from the sale in US dollars of local bonds denominated in Argentine pesos (bonds with dual peso denomination/dollar).

------

From the second quarter of 2025, and considering the liberalization of the foreign exchange market and the elimination of restrictions on the purchase of foreign currency by individuals, and the value of this CCL dollar exchange rate does not differ significantly from other market rates and the official exchange rate, Grupo Santander started using the official exchange rate as a reference once again.

During the nine-month period ended on 30 September 2025, there were no additional significant changes to the estimates made at the end of the 2024 financial year, other than those indicated in these interim financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;***d)&nbsp;&nbsp;&nbsp;&nbsp;Contingent assets and liabilities***

Note 25 to Grupo Santander's consolidated annual accounts for the year ended 31 December 2024 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 2024 to the date of formal preparation of these interim financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;***e) Comparative information***

The information for the year 2024 contained in these interim financial statements is only presented for comparison purposes with the information relating to the nine-month period ended 30 September 2025.

The information in the interim income statement from the first nine months of 2024 has been restated, as a result of the agreement for the sale of Santander Bank Polska by Grupo Santander, as required by IFRS 5 (see Notes 2 and 6).

Likewise, the information in Note 12 related to segment information for September 2024 has been restated, in accordance with the changes in the segments' composition of Grupo Santander, as required by IFRS 8 (see Note 12).

In order to interpret the changes in the balances with respect to 31 December 2024, 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 51.b to the consolidated annual accounts for the annual year ended 31 December 2024) and the impact of the appreciation/depreciation of the various currencies against the euro in the first nine months of 2025: Mexican peso (0.14%), US dollar (-11.45%), Brazilian real (2.81%), Argentinian peso (-23.45%), Pound sterling (-4.96%), Chilean peso (-8.39%) and Polish zloty (0.24%); as well as the evolution of the average exchange rates between comparable periods: Mexican peso (-11.84%), US dollar (-2.7%), Brazilian real (-10.01%), Pound sterling (0.08%), Chilean peso (-4.72%) and Polish zloty (1.53%).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***f)&nbsp;&nbsp;&nbsp;&nbsp; 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 nine-month period ended 30 September 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***g)&nbsp;&nbsp;&nbsp;&nbsp;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 nine-month period ended 30 September 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***h) Other information***

On 29 May 2025, Order HAC/532/2025 of 26 May was published, which establishes the obligation to self-assess and pay the tax on the interest and commission margins of certain financial institutions, approved by Law 7/2024 of 20 December. Banco Santander appealed against this Ministerial Order, requesting its suspension, but at the date of these interim financial statements the request had not been resolved. As a result, in June and in September the tax payment of EUR 392 million corresponding to the 2024 margins was made, and the corresponding asset was recorded under 'Financial assets at amortised cost - loans and advances to customers'.

The accrued tax at 30 September 2025 for 2025 interest and commission margins is recognised in the tax expense line of the income statement for an amount of EUR 263 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***i)&nbsp;&nbsp;&nbsp;&nbsp;Events after the reporting period***

From 1 October to the date of authorization of these interim financial statements for the first nine months of 2025, no significant events other than those indicated therein have occurred.

---

| | | |

During the first nine months of 2025 there has been an decrease in goodwill of EUR 1,413 million, of which EUR 1,178 million corresponds to the reclassification in the consolidated balance sheet of the goodwill of Santander Bank Polska under the heading 'Non-current assets held for sale' (see Notes 2 and 6). The remaining amount is mainly due to exchange differences (see Note 11), which 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.

Note 17 of the consolidated annual accounts for the year ended 31 December 2024 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.

In accordance with IAS 36, a Cash Generating Unit (CGU) to which goodwill has been assigned should be subjected to an annual impairment test, and when there are signs of impairment.

In accordance with all mentioned before and the analysis made of the information available on the evolution of the different cash-generating units that could reveal the existence of indications of impairment, the directors of the Grupo Santander have concluded that during the first nine months of 2025 , there were no triggers that required the recording of impairments.

&nbsp;&nbsp;&nbsp;&nbsp; ***d) Fair value of financial liabilities not measured at fair value***

Following is a comparison between the value by which Grupo Santander's financial liabilities are recorded that are measured using criteria other than fair value and their corresponding fair value at 30 September 2025 and 31 December 2024:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | EUR million | EUR million | EUR million | EUR million |

**<u>10. Provisions</u>**

&nbsp;&nbsp;&nbsp;&nbsp;***a)&nbsp;&nbsp;&nbsp;&nbsp;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 2024 to 30 September 2025, is mainly due to net provisions against equity for changes in financial assumptions and other experience adjustments, and also to benefit payments, premiums and contributions (see Note 11.d).

&nbsp;&nbsp;&nbsp;&nbsp;***b)&nbsp;&nbsp;&nbsp;&nbsp;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 September 2025 and at 31 December 2024 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 | EUR million |
| | **30-09-2025** | **31-12-2024** |

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 Grupo Santander 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 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 of the different offices of the Group.

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.

With respect to changes in provisions in the first nine months of 2025, for employment and other legal proceedings, in Brazil, provisions of EUR 393 million and EUR 122 million were recorded, making payments of EUR 273 million and EUR 118 million, respectively.

***c)&nbsp;&nbsp;&nbsp;&nbsp;Litigation and other matters***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**i. Tax-related litigation**

At 30 September 2025 the main tax-related proceedings concerning the Group were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• 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 Programa de Integraçao Social (PIS) and Contribuição para Financiamento da Seguridade Social (COFINS), 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 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 Federal Supreme Court also admitted the appeals related to the other Group entities both for PIS and COFINS. On June 13, 2023, the Federal Supreme Court ruled unfavorably two cases through General Repercussion (Theme 372), including Banco Santander (Brasil) S.A. case. The Bank has filed a new appeal, considering the possible loss as a contingent liability. The cases of the other Group entities are no longer susceptible of appeal and a provision has been recognized for the amount of the estimated loss.

&nbsp;&nbsp;&nbsp;&nbsp;• 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 (Imposto sobre a Renda das Pessoas Jurídicas - IRPJ - and Contribuçao Social sobre o Lucro Liquido -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, which involves several cases, are pending decision in different administrative and judicial instances. No provision was recognised in connection with the amount considered to be a contingent liability.

&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;• 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 (Contribuição Provisória sobre Movimentação Financeira) 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. This case is in the scope of the Comprehensive Transaction Programme (Programa de Transaçao Integral) established by the Ministry of Finance. The formal acts of consolidation and approval of the transaction are pending. The amounts established in the transaction are fully provisioned.

&nbsp;&nbsp;&nbsp;&nbsp;• In December 2010 the Brazilian tax authorities issued an infringement notice against Santander Seguros S.A. (Brasil), (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) (currently Zurich Santander Brasil Seguros e Previdência S.A.), 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.

&nbsp;&nbsp;&nbsp;&nbsp;• 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. The Bank appealed before the Higher Chamber of CARF, and a final favourable decision was obtained in April 2024. No provision was recognised in connection with this proceeding as it was considered to be a contingent liability.

&nbsp;&nbsp;&nbsp;&nbsp;• 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. In May and October 2024, the appeal related to period 2009 to 2012 was finally rejected by the CARF and the resolution was appealed at the Federal Justice. No provision was recognised in connection with this matter as it was considered to be a contingent liability.

&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;• 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 of year 2009 and 2019. The appeals are pending decision at the administrative level. No provision was recognised in connection with this matter as it is considered to be a contingent liability.

&nbsp;&nbsp;&nbsp;&nbsp;• Banco Santander (Brasil) S.A. filed a suspensive judicial measure aiming to avoid the withholding income tax (Imposto sobre a Renda Retido na Fonte - IRRF), on payments derived from technology services provided by Group foreign entities. A favorable decision was handed down and an appeal was filed by the tax authority at the Federal Regional Court, where it awaits judgment. No provision was recognized as it is considered to be a contingent liability.

&nbsp;&nbsp;&nbsp;&nbsp;• 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. The tax assessment notices were appealed to the CARF. In 2024, the CARF issued a favourable partial decision on both infraction notices. In December 2024, the tax authorities issued a new infringement notice for 2019 and 2020. 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 762 million, and for lawsuits that qualify as contingent liabilities is EUR 5,222 million.

At the date of approval of these interim financial statements, there are other less significant tax disputes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**ii. Non-tax-related proceedings**

At 30 September 2025 the main non-tax-related proceedings concerning the Group were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• Payment Protection Insurance (PPI): AXA France IARD and AXA France Vie (former GE Capital Corporation Group entities, known as Financial Insurance Company Ltd (FICL) and Financial Assurance Company Ltd (FACL), acquired by AXA SA in 2015) (together, AXA France) brought a claim against (i) Santander Cards UK Limited (formerly known as GE Capital Bank Limited (GECB), which was acquired by Banco Santander, S.A. in 2008 and subsequently transferred to Santander UK plc); and (ii) Santander Insurance Services UK Limited (a Banco Santander, S.A. subsidiary) (SISUK and together with GECB the Santander Entities). The claim relates to the allocation of liability for compensation and associated costs in respect of a large number of PPI policies distributed by GECB pre-2005, which were underwritten by FICL and FACL.

------

On 25 July 2025, the Commercial Court of England and Wales handed down its judgment in relation to the claim brought by AXA France (the Judgment). It found against SISUK in relation to AXA France's claim pursuant to an indemnity in an agency agreement entered into between GECB, FICL and FACL in 2000 and novated by GECB to SISUK in 2010. It also found GECB negligent in the sale of PPI policies, but this element of the claim was time barred to PPI policies sold in the period between 2002 and 2005 and overlaps with the indemnity claim. The Santander Entities applied to the Court of Appeal for permission to appeal. The permission was granted on 21 October 2025 and, consequently, the Santander Entities will now file their challenge of appeal.

No customers have suffered loss as a consequence of the claim brought by AXA France or the Judgment, nor does it impact upon past redress paid to customers for PPI complaints.

&nbsp;&nbsp;&nbsp;&nbsp;• Motor Finance Broker Commissions: following the Financial Conduct Authority's (FCA) Motor Market review in 2019 which resulted in a change in rules in January 2021, Santander Consumer (UK) plc (SCUK) has received several of county court claims and complaints in respect of its historical use of discretionary commission arrangements (DCAs) prior to the 2021 rule changes. In January 2024 the FCA commenced a review of the use of DCAs between lenders and credit brokers (the FCA Review). Pending the conclusion of its review, the FCA first paused the handling of DCA complaints and then extended this to motor finance commission related complaints which are now paused until 4 December 2025. A claim was issued against SCUK, Santander UK plc and others in the Competition Appeal Tribunal , alleging that SCUK's historical DCAs in respect of used car financing operated in breach of the Competition Act 1998. This is currently paused until the end of October 2025 connected to the outcome of the FCA Review.

In light of the Court of Appeal's judgment of October 2024, rendered in the judicial proceedings involving other financial entities, the Santander UK Group Holdings (Santander UK) recognised a provision of GBP 283.4 million (EUR 324.7 million) in relation to historical motor finance commission payments. This included estimates operational and legal costs and potential awards based on various using a range of assumptions. This judgment was appealed before the Supreme Court.

On 1 August 2025, the Supreme Court handed down its judgment that motor dealers acting as credit brokers do not owe fiduciary or disinterested duties to their customers and, as a consequence, commission payments by lenders to motor dealers would not be unlawful on that basis. In addition, the Supreme Court held that an unfair relationship under s.140A of the Consumer Credit Act 1974 had arisen in the Johnson case on its facts and awarded the amount of the commission paid by the lender plus interest at a commercial rate as the remedy. It also confirmed that the test for unfairness was highly fact sensitive and it outlined a series of non-exhaustive factors to consider in assessing unfair relationships in this context (indicating that no or partial disclosure was not necessarily enough on its own to constitute an unfair relationship).

Following the Supreme Court's judgment, on 3 August, the FCA announced that it aimed to publish a consultation on an industry wide redress scheme in early October, and that this consultation would be open for six weeks. In early September 2025, the appeal to the Court of Appeal of the High Court's judicial review of a final decision by the Financial Ombudsman Service against another lender (which alongside the Supreme Court case was highly relevant to the outcome of the FCA's Review) was discontinued.

On 7 October 2025, the FCA published its proposals for an industry-wide redress scheme under s404 of the Financial Services and Markets Act to compensate motor finance customers and launched a public consultation period. We are reviewing the proposal in detail to understand its potential implications. The deadline for a response on the substantive aspects of the Consultation is 18 November 2025.

Although the FCA expects to publish its policy statement and final rules in early 2026, with the redress scheme to launch the day after the publication of the rules, the final version of the scheme will be dependent on the consideration given to the responses it receives, and its application will be subject to any legal challenges which may ultimately be brought against it as well as by the claims filed by lenders or consumer groups. The FCA's proposed approach differs in some respects from the Supreme Court's ruling. There is therefore uncertainty regarding the final scope, methodology and timing of any redress scheme that may ultimately be implemented.

Santander UK is therefore reviewing the potential effects and impact of the above circumstances, although to date and as a consequence of the referred uncertainties, the provision already recognized has not been modified. While the ultimate financial impact of this matter could materially differ from the amount of the provision as of this date, such impact is not expected to be material for the Group as of the date of these interim financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;• Delforca: dispute arising from equity swaps entered into by Gaesco (now Delforca 2008, S.A. (Delforca)) 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, S.A., parent of Delforca (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, Monesa and the bankruptcy administrator. On 1 June 2023, the appeal hearing took place and on 15 November 2023 the Provincial Court of Barcelona rendered a judgment dismissing the appeals filed by Delforca, Monesa and the bankruptcy administrator and confirming the first instance judgment. Delforca and Monesa (not the bankruptcy administrator) have filed an appeal in cassation before the Supreme Court against the judgment of the Provincial Court of Barcelona.

Separately, Monesa, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 (the STF and the Collective Agreement). 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 proved 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 Collective Agreement for 5 additional years starting from 3 June 2020. Condition for this extension was to include in the Collective Agreement actions related to the 'Collor I Plan'. On May 2025, the STF issued the judgment recognizing the constitutionality of the Bresser, Verão, Collor I and II plans, guaranteeing savers the receipt of the amounts established in the Collective Agreement and setting a deadline of 24 months for new adhesions. As of 30 September 2025, the provision recorded for the economic plan proceedings amounts to EUR 161.5 million.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Banco Popular´s acquisition: after the declaration of the resolution of Banco Popular, some investors filed claims against the EU's Single Resolution Board decision, and the FROB's resolution executed in accordance with the aforementioned decision. Likewise, numerous civil lawsuits 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 the direct appeals filed before the General Court of the European Union (EGC) and the Court of Justice of the European Union (CJEU), all appeals were either dismissed or discontinued. Currently, there are no ongoing appeals.

In the civil proceedings, several Spanish judges referred to the CJEU a number of preliminary questions that have already been resolved. In particular, in the judgments of 5 May 2022 (C-410/20) and 5 September 2024 (C-775/22, C-779/22, C-794/22), the CJEU stated that Directive 2014/59/EU on bank resolution prevents shareholders, subordinated debt holders, and holders of equity instruments converted into shares bringing actions against a financial institution subject to a resolution proceeding or against its successor after the resolution, claiming liability for the information contained in the prospectus, under Directive 2003/71/EC, or actions seeking the nullity of the contract of subscription of capital instruments, which, given its retroactive effects, would result in the refund of the value of such securities, plus the interest accrued as of the date of execution of the contract. In its 11 September 2025 resolutions (C-687/23 and C-447/23), the CJEU declared that the above referred TJUE resolutions do not apply to actions pursued prior to the entity's resolution. There are currently no other preliminary questions under consideration.

On 4 March 2024, in the context of preliminary proceedings 42/2017, the Central Court of Instruction No. 4 issued a ruling transforming the proceedings into Summary Proceedings and terminating the investigation phase. The ruling considers that the circumstantial evidence resulting from the investigation which could constitute a crime is basically the following: (i) an alleged misrepresentation in the prospectus of the 2016 capital increase of Banco Popular; (ii) an alleged misrepresentation in the annual accounts of Banco Popular for 2015, the interim financial statements for 2016 and the annual accounts for 2016; and (iii) the offer to the market of a distorted amount of regulatory capital, after the capital increase of 2016 (for allegedly having been granted by Banco Popular financing to clients for the subscription of shares in the aforementioned capital increase, without discounting it from the regulatory capital). According to the aforementioned ruling, these facts could constitute the crimes of fraud of investors (art. 282 of the Criminal Code) and accounting falsehood (art. 290 of the Criminal Code). All appeals filed against the ruling have been dismissed.

The accusing parties, including the Public Prosecutor's Office, filed their indictment briefs on 28 October 2024, which included requests for compensation for civil liability and the request that not only the defendants but also several entities are held liable for such compensation, including Banco Santander, S.A., the auditing firm and several insurance companies. Following the filing of the indictment briefs, on 22 November 2024, the Court (Investigating Judge) issued an order for the opening of the oral trial against the defendants and civil liability parties, including Banco Santander, S.A. as a possible civil liable party. However, in line with what was determined by the Spanish National Court and confirmed by the Supreme Court concerning the hypothetical succession of Banco Popular by Banco Santander, S.A., the oral trial has not been opened against the Bank as possible direct civil liable party.

The order to open the oral trial states that the plaintiffs have requested compensation for civil liability for a total amount of EUR 2,277.65 million. Additionally, the order rejects the imposition of the guarantee requested by several of the accusing parties, considering that it is unnecessary to secure the outcome of the trial. The defendants and potential civil liable parties submitted their defense writs on 4 February 2025. After that, the proceedings will be forwarded to the Criminal Chamber of the National Court for the oral trial.

Regarding the civil liability, the Bank considers that it has no subsidiary civil liability in light of the CJEU's judgments of 5 May 2022 (C-410/20), 5 September 2024 (C-775/22, C-779/22, C-794/22) and 11 September 2025 (C-687/23 and C-447/23). Notwithstanding the foregoing, the Spanish National Court has stated that this issue shall be resolved within the ongoing proceedings.

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. On 15 December 2024, Banco Santander, S.A., proceeded to redeem in advance voluntarily all bonds in circulation regarding such commercial action. The CJEU judgements of 5 May 2022 (C-410/20), 5 September 2024 (C-775/22, C-779/22, C-794/22) and 11 September 2025 (C-687/23 and C-447/23) referred above, represented a very significant reduction in the risk associated with these claims.

&nbsp;&nbsp;&nbsp;&nbsp;• 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 consequences (penalties and/or disgorgement of proceeds), cannot be anticipated. For this reason, the Bank has not recognized any provisions in relation to the potential imposition of financial penalties.

&nbsp;&nbsp;&nbsp;&nbsp;• Banco Santander, S.A. was sued in a legal proceeding in which the plaintiff alleges that the Bank breached his contract as CEO of the institution: in the lawsuit, the claimant mainly requested a declaratory ruling upholding the existence, validity and effectiveness of such contract and its enforcement together with the payment of certain amounts. For the case that 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 legal action stating that the conditions to which the appointment of that position was subject to were not met; that the executive services contract required by law was not concluded; and that in any case, the parties could terminate the contract without any justified cause.

On 17 May 2021, the plaintiff reduced his claims for compensation to EUR 61.9 million. On 9 December 2021, the Court upheld the claim and ordered the Bank to compensate the claimant in the amount of EUR 67.8 million. By court order of 13 January 2022, the Court corrected and supplemented its judgment, reducing the total amount to be paid by the Bank to EUR 51.4 million and clarifying that part of this amount (buy out) was to be paid under the terms of the offer letter, i.e., entirely in Banco Santander shares, within the deferral period for this type of remuneration at the plaintiff's former employer and subject to the performance metrics or parameters of the plan in force at the Bank, which was that of 2018. As explained in note 5 of the report of the consolidated annual accounts of the year 2022, the degree of performance of these objectives was 33.3%.

The Bank filed an appeal against the judgment before the Madrid Court of Appeal, which was opposed by the plaintiff. At the same time, the plaintiff filed an application for provisional enforcement of the judgment in the First Instance Court. A court order was issued ordering enforcement of the judgment, and the Bank deposited in the court bank account the full amount provisionally awarded to the claimant, including interest, for an approximate sum of EUR. 35.5 million, within the voluntary compliance period.

On 6 February 2023, Banco Santander was notified with the judgment of 20 January 2023 by which the Madrid Court of Appeal partially upheld the appeal filed by the Bank. The judgment has reduced the amount to be paid by EUR 8 million, which, to the extent that this amount was already paid in the provisional partial enforcement of the judgement of first instance court, must be returned to the Bank together with other amounts for interest, which the appeal judgement also rejects. The plaintiff deposited circa EUR 9.6 million. This amount was received by the Bank on 11 July 2023. On 11 April 2023, the Bank filed an extraordinary appeal for procedural infringement and an appeal in cassation against the Madrid Court of Appeal's judgment before Spanish Supreme Court. The extraordinary and cassation appeals submitted by the Bank were accepted on 26 March 2025 and are pending to be resolved. Existing provisions cover the estimated risk of loss.

&nbsp;&nbsp;&nbsp;&nbsp;• CHF Polish Mortgage Loans: on 3 October 2019, the CJEU rendered its decision in relation to a judicial proceeding against an unrelated bank in Poland regarding the consequences of potentially unfair contractual clauses in CHF-Indexed loan agreements. The CJEU left it up to national courts to decide in this regard, indicating that it is possible to invalidate a contract if it cannot be maintained without the abusive terms and there are no explicit supplementary provisions that can replace these terms.

On 15 June 2023, the CJEU issued its judgment in Case C-520/21, in which it confirmed that it is national law that is relevant to determine the effect of cancellation of a contract - respecting the principles arising from Directive 93/13/EEC. According to the ruling of the CJEU in that case, the bank's claims in excess of the repayment of the nominal amount of the loan's principal and, as the case may be, the payment of default interest are contrary to the objectives of Directive 93/13/EEC if they were to lead to a profit analogous to the one it intended to make from the performance of the contract and thus eliminate the deterrent effect.

On 25 April 2024, the Civil Chamber of the Supreme Court rendered a decision according to which: (i) in the event that a provision of an indexed or denominated loan agreement relating to the manner of determining the exchange rate of a foreign currency constitutes an abusive contractual term and is not binding, based on the current case law, it is not possible for this provision to be replaced by any other method of determining exchange rates under the law or prevailing practices; (ii) in the event that it is not possible to determine a foreign currency exchange rate binding for the parties in an indexed or denominated credit agreement, the agreement is not binding. Further, referring to the issues related to the cancellation of a credit agreement, the Supreme Court pointed out that: (i) if the bank has paid all or part of the credit amount to the borrower and the borrower has made repayments of the credit, independent claims for the repayment of the undue payment arise in favour of each party (the so-called two condition theory); (ii) the limitation period of the bank's claim for reimbursement of amounts paid under the credit begins from the day following the day on which the borrower challenged the bindingness of the terms of the agreement; (iii) there is no legal basis for either party to claim interest or other benefits for the use of its funds during the period between the undue payment and the date when the repayment became due. The criteria set out by the Supreme Court in its decision could clarify the previous decisions described above. Nine judges of the Supreme Court declined to participate in the resolution raising questions of a constitutional nature and six judges submitted dissenting opinions mainly on issues related to the maintenance of the agreement after the elimination of abusive clauses.

Santander Bank Polska and Santander Consumer Bank Poland estimate legal risk using a model which considers different possible outcomes and regularly monitor court rulings on foreign currency loans to verify changes in case law practice, including the impact of the aforementioned Supreme Court resolution on this case law. The Bank is reaching settlements with customers who have taken legal action as well as with those who have not yet decided to file a lawsuit. The settlement scenario is reflected in the model used to calculate provisions for legal risks.

As of 30 September 2025, Santander Bank Polska S.A. and Santander Consumer Bank S.A. maintained portfolios of loans affected by the legal risk connected with CHF-indexed loan agreements for an approximate gross amount of PLN 3,958.2 million (EUR 928.1 million).

As of 30 September 2025, the total value of adjustment to gross carrying amount in accordance with IFRS9 as well as provisions recorded under IAS37, amount to PLN 6,011.3 million (EUR 1,409.5 million) of which PLN 3,677.9 million (EUR 862.4 million) corresponds to adjustment to gross carrying amount under IFRS 9 and PLN 2,333.3 million (EUR 547.1 million) to provisions recognized in accordance with IAS 37. The adjustment to gross carrying amount in accordance with IFRS9 during the first nine months of 2025 amounted to PLN 42.6 million (EUR 10.1 million), the additional provisions under IAS 37 amounted to PLN 726.0 million (EUR 171.2 million). Other costs related to the dispute amounted to PLN 483.2 million (EUR 114.0 million).

The above figures include Santander Bank Polska and Santander Consumer.

These provisions represent the best estimate as of 30 September 2025. Santander Bank Polska and Santander Consumer Bank Poland will continue to monitor and assess the appropriateness of those provisions.

&nbsp;&nbsp;&nbsp;&nbsp;• Banco Santander Mexico: dispute regarding a testamentary trust constituted in 1994 by Mr. Roberto Garza Sada in Banca Serfin (currently Santander Mexico) in favor of his four sons in which he affected shares of Alfa, S.A.B. de C.V. (respectively, Alfa and the Trust). During 1999, Mr. Roberto Garza Sada instructed Santander México in its capacity as trustee to transfer 36,700,000 shares from the Trust's assets to his sons and daughters and himself. These instructions were ratified in 2004 by Mr. Roberto Garza Sada before a Notary Public.

Mr. Roberto Garza Sada passed away on 14 August 2010 and subsequently, in 2012, his daughters filed a complaint against Santander Mexico alleging it had been negligent in its trustee role. The lawsuit was dismissed at first instance in April 2017 and on appeal in 2018. In May 2018, the plaintiffs filed an appeal (recurso de amparo) before the First Collegiate Court of the Fourth Circuit based in Nuevo León, which ruled in favor of the plaintiffs on 7 May 2021, annulling the 2018 appeal judgment and condemning Santander Mexico to the petitions claimed, consisting of the recovery of the amount of 36,700,000 Alfa shares, together with dividends, interest and damages.

Santander Mexico has filed various constitutional reviews and appeals against the recurso de amparo referred to above, which have been dismissed by the Supreme Court of Justice of the Nation. As of this date, an amparo review filed by the Bank is pending to be resolved in the Collegiate Courts in the State of Nuevo León, thus the judgment is not final.

The Bank asked the Supreme Court of Justice of the Nation to take up the matter, what was accepted and consequently, the Supreme Court of Justice will resolve the matter. In addition, the Bank filed two recursos de reclamación against the non-admission of the recurso de revisión extraordinario issued by the then president of the Supreme Court of Justice of the Nation. On 25 June 2025, one of such recursos de reclamación was accepted and this decision was extended to the remaining one, both will now be resolved. In case that these recursos against the non-admission are resolved favourably, the Supreme Court of the Nation will then decide on the merits of the recurso de revisión extraordinario against the judgment which condemned the Bank.

Santander México believes that the actions taken should prevail and reverse the decision against it. The impact of a potential unfavorable resolution for Santander México will be determined in a subsequent proceeding and will also depend on the additional actions that Santander México may take in its defense, so it is not possible to determine it at this time. At the current stage of the proceedings, the provisions recorded are considered to be sufficient to cover the risks deriving from this claim.

&nbsp;&nbsp;&nbsp;&nbsp;• Mortgage Expenses: In December 2015 the Spanish Supreme Court ruled that mortgage clauses relating to the payment of fees associated to formalizing the mortgage were abusive. On 27 November 2018, the Supreme Court agreed that the taxpayer of the documented legal acts stamp duty tax (IAJD) on the mortgage loans should be the borrower. On 9 November 2018, RDL 17/2018 came into force and modified the Law of the IAJD, establishing that the taxpayer is the Bank. On 23 January 2019, the Supreme Court ruled the distribution of the same must be 50% between the Bank and the borrower in public notary expenses and agency expenses. The Supreme Court also ruled that the Bank must pay 100% of the Registry. On 26 October 2020, the Supreme Court ruled that the Bank is fully responsible for the management expenses; and on 27 January 2021, the Supreme Court ruled that the Bank is also responsible for the valuation expenses.

In relation to the statute of limitations, on 25 April 2024, two judgments were rendered (cases C-561/21 and C-484/21) in which the Court of Justice of the European Union (CJEU) stated that the commencement of the statute of limitations for the annulment of the mortgage expenses shall be fixed on the moment when the consumer has an effective knowledge of the abusive nature of the clause and its effects and that this date must not be fixed (a) on the date of payment of such expense nor of the execution of the agreement; (b) when the Supreme Court has handed down judgments stating the abusive nature of a clause similar to the one included in the consumer contract; nor (c) when the CJEU has handed down judgments confirming that the statute of limitations for the annulment of contractual provisions is valid subject to its compliance with the principles of equivalence and effectiveness.

The Supreme Court has confirmed this criterion in its 14 June 2024 judgment, establishing that the public dissemination of case-law declaring the abusive nature of a clause does not necessarily give rise to the limitation period of the reimbursement action derived from similar clauses. However, the 4 July 2024 judgment, rendered in the case C-450/22, the CJEU has established that it cannot be excluded a priori that, as a consequence of the occurrence of an objective event or of a notorious event, such as the amendment of the applicable legislation or a widely disseminated and debated development of jurisprudence, the court considers that the average consumer's overall perception of the floor clause has changed during the reference period and has enabled him to become aware of the potentially significant economic consequences arising from such clause. A further preliminary question concerning the statute of limitations of the annulment of mortgage expenses has been raised before the CJEU by the First Instance Court No 8 of La Coruña. In December in 2024, the Supreme Court handed down two additional judgments regarding statute of limitations, in which it determines that the date to be considered for the purposes of the application of Directive 93/1994 and, consequently, the statute of limitations detailed in its previous judgments, is 31 December 1994 (i.e. the date when the deadline for its transposition ended). This is based on the principle of interpretation in accordance with directives not transposed (applicable once their transposition period has expired). The recorded provision includes the best estimate of Group's liability for this matter.

Banco Santander, S.A. and the other Group companies are subject to claims and, therefore, are party to certain legal proceedings incidental to the normal course of their business including those in connection with lending activities, relationships with employees and other commercial or tax matters additional to those referred to here.

With the information available to it, the Group considers that, at 30 September 2025, it had reliably estimated the obligations associated with each proceeding and had recognized, where necessary, sufficient provisions to cover reasonably any liabilities that may arise as a result of these tax and legal risks. Those cases in which provisions have been registered but are not disclosed are justified on the basis that it would be prejudicial to the proper defense of the Group. Subject to the qualifications made, the Group believes that any liability arising from such claims and proceedings will not have, overall, a material adverse effect on the Group's business, financial position, or results of operations.

**<u>11. Equity</u>**

In the nine-month periods ended 30 September 2025 and 2024 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.

&nbsp;&nbsp;&nbsp;&nbsp;***a)&nbsp;&nbsp;&nbsp;&nbsp;Capital***

Banco Santander's share capital at 30 September 2025 and 31 December 2024 consisted of EUR 7,443 and 7,576 million, represented by 14,885,325,372 and 15,152,492,322 shares, respectively, of EUR 0.50 of nominal value each and all of them of a unique class and series.

On 3 June 2025, there was a capital reduction amounting to EUR 133,583,475 through the redemption of 267,166,950 shares, corresponding to the share buyback program carried out between February and June 2025.

The transaction did not involve the return of contributions to shareholders, as the Bank holds the redeemed shares.

&nbsp;&nbsp;&nbsp;&nbsp;***b)&nbsp;&nbsp;&nbsp;&nbsp;Share premium***

As a result of the capital reduction described in Note 11.a, during the first semester of 2025, the share premium has been reduced by EUR 1,453,416,348 corresponding to the difference between the purchase value of the shares amortised (EUR 1,586,999,823) and the nominal value of said shares (EUR 133,583,475) (see Total Statement of Changes in Shareholders' Equity). Likewise, and in accordance with applicable legislation, a reserve for amortized capital has been allocated with a charge to the share premium for an equal amount to the nominal value of said amortised shares (EUR 133,583,475).

&nbsp;&nbsp;&nbsp;&nbsp;***d) Other comprehensive income - Items not reclassified to profit or loss - Actuarial gains or losses on defined benefit pension plans***

The balance of the heading Other accumulated comprehensive income - Items not reclassified to profit or loss - Actuarial gains or losses on defined benefit pension plans, includes the actuarial gains or losses and the return on the assets assigned to the plan, less administration costs and plan's own taxes, and any change in the effects of the asset limit, excluding amounts included in net interest on net defined benefit liability (asset). Its variation is shown in the consolidated condensed statement of recognized income and expense.

During the first nine months of 2025, the amount of actuarial losses (net of actuarial gains) has increased by EUR 33 million. The main impacts are:

In first place, due to the higher addition against equity amounting to EUR 173 million, with the following breakdown:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increase of EUR 108 million in the accumulates actuarial losses relating to the Group´s entities in the United Kingdom, mainly due to the evolution experienced by the portfolio, partially compensated by the increase in the discount rate - from 5.54% to 5.88%- and to the reduction in short term inflation -from 3.11% to2.93%-.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increase of EUR 91 million in the accumulates actuarial losses relating to the Group´s entities in Brazil, mainly due to the evolution experienced by the discount rate -reduction from 10.58% to 10.52% in pension plans and from 10.50% to 10.42% in medical plans-, to the short term inflation and the evolution in the asset portfolio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Decrease of EUR 31 million in the accumulates actuarial losses relating to the Group´s entities in Germany, mainly due to the evolution experienced by the discount rate -increase from 3.56% to 4.15%-.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Decrease of EUR 27 million in the accumulates actuarial losses relating to the Group´s entities in Spain, mainly due to the evolution experienced by the discount rate -increase from 3.00% to 3.60%-.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increase of EUR 10 million in the cumulative actuarial losses relating to the Group's businesses in Portugal, mainly due to the evolution of the collective.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increase of EUR 22 million in the cumulative actuarial losses relating to the Group's businesses in other geographical areas.

In second place, due to the evolution of exchange rates, a EUR 140 million decrease, mainly due to the depreciation of the pound sterling.

&nbsp;&nbsp;&nbsp;&nbsp;***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 September 2025 and 31 December 2024 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:

&nbsp;&nbsp;&nbsp;&nbsp;***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 nine months of 2025 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 general depreciation of the currencies, except the Brazilian real, Chilean peso and the Polish zloty (see Note 1.e).

Of this variation, a capital loss of EUR 219 million corresponds to the valuation at the closing exchange rate of goodwill for the first nine months of 2025 (see Note 8).

&nbsp;&nbsp;&nbsp;&nbsp;***g) Other comprehensive income – Items that may be reclassified to profit or loss – Changes in the fair value of debt instruments 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.

Below is a breakdown of the composition of the balance as of 30 September 2025 and 31 December 2024 under Other comprehensive income - Items that may be reclassified to profit or loss - Changes in the fair value of debt instruments measured at fair value through other comprehensive income depending on the type of instrument and the geographical origin of the issuer:

**<u>12. Segment information (Primary segments)</u>**

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 business units in which benefits are obtained or by geography. The information is prepared by aggregating the figures for Grupo 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.

During the first nine months of 2025, Grupo Santander made changes to the composition of its primary segments, as well as to the criteria for allocating profit among them, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To better align reporting with the changes to the management structure in Wealth Management & Insurance, investment platforms (Investment Platforms Unit) and certain stakes in companies, mainly in the real estate sector, that were previously recorded in Retail and Commercial Banking or Corporate and Investment Banking have been incorporated into Wealth Management & Insurance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Profit sharing criteria between Retail & Commercial Banking and Cards has been improved, aligning criteria across the Group.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Additionally, it has been completed the usual annual adjustment of the perimeter of the Global Customer Relationship Model between Retail & Commercial Banking and Corporate & Investment Banking and between Retail & Commercial Banking and Wealth Management & Insurance.

The Group's main level of segmentation, derived from its management model, consolidates the Group's businesses under five business areas:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Retail & Commercial Banking (Retail): area that integrates the retail banking and commercial banking business (individuals, SMEs and corporates), except private banking clients and business originated in the consumer finance and the cards businesses. Detailed financial information is provided on Spain (Retail Spain), the UK (Retail UK), Mexico (Retail Mexico) and Brazil (Retail Brazil), which represent the majority of the total Retail business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Digital Consumer Bank (Consumer): comprises all business originated in the consumer finance companies, plus Openbank, Open Digital Services (ODS) and SBNA Consumer. Detailed financial information is provided on Europe (DCB Europe) and US (DCB US).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Corporate & Investment Banking (CIB): this business, which includes Global Transactional Banking, Global Banking (Global Debt Finance and Corporate Finance) and Global Markets, offers products and services on a global scale to corporate and institutional customers, and collaborates with other global businesses to better serve our broad customer base.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Wealth Management & Insurance (Wealth): includes the corporate unit of Private Banking and International Private Banking in Miami and Switzerland (Santander Private Banking), the asset management business (Santander Asset Management), the insurance business (Santander Insurance) and the unit that manages the investment platforms and stakes that complement Wealth's traditional business (the new vertical, Portfolio Investments).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Payments: comprises the Group's digital payments solutions, providing global technology solutions for the banks and new customers in the open market. It is structured in two businesses: PagoNxt (Getnet, Ebury and PagoNxt Payments) and Cards (cards platform and business in the countries where Group operates).

In accordance with the information used by the Group's executive committee for decision making, following is a distribution of the gross margin by business segment accompanying consolidated income statements for the nine-month periods ended 30 September 2025 and 2024.

In addition to these operating units, which report by businesses and geographic area, 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.

The financial instruments at fair value determined on the basis of published price quotations in active markets (level 1) include government debt securities, private-sector debt securities, derivatives traded in organised markets, securitised assets, shares, short positions and fixed-income securities issued.

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 nine months of 2025 and 2024, 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 types of derivatives, and the related valuation techniques and inputs, by asset class, are detailed in the consolidated annual accounts as at 31 December 2024.

As the end of 30 September 2025, the CVA (Credit Valuation Adjustment) accounted for was EUR 219 million (a decrease of 19.5% compared to 31 December 2024) and adjustments of DVA (Debt Valuation Adjustment) was EUR 280 million (a decrease of 11.7% compared to 31 December 2024). The reduction in CVA is due to the evolution in the models used to calculate spread curves for certain counterparties, movements in credit markets, market movements in interest rate and foreign exchange risk factors, while the reduction in DVA is due reductions in credit markets.

(\*) The internal models of level 2 implement figures based on the parameters observed in the market, while level 3 internal models use significant inputs that are not observable in market data.

(\*\*)&nbsp;&nbsp;&nbsp;&nbsp; Includes mainly temporary acquisitions/disposals of assets with corporate clients and, to a lesser extent, with central banks.

(\*\*\*) Includes mainly syndicated loans under the HTC&S business model.

(\*\*\*\*) Includes mainly short-term deposits that are managed based on their fair value.

*<u>Level 3 financial instruments</u>*

Set forth below are the Group's main financial instruments measured using unobservable market data as significant inputs of the internal models (level 3):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Illiquid equity instruments in non-trading portfolios, classified at fair value through profit or loss and at fair value through equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Long-term temporary acquisitions/disposals of assets with corporate clients based on underlying assets for which no observable credit curve exists. To a lesser extent, repos/reverse repos with central banks on illiquid government-backed underlying assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Callable interest rate derivatives (Bermudan-style options) where the main unobservable input is mean reversion of interest rates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Trading derivatives on interest rates, taking as an underlying asset titling and with the amortization rate (CPR, Conditional prepayment rate) as unobservable main entry.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Derivatives from trading on inflation in Spain, where volatility is not observable in the market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Equity volatility derivatives, specifically indices and equities, where volatility is not observable in the long term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 nine months of 2025 arising from models whose significant inputs are unobservable market data (level 3) amounted to a loss of EUR 75 million (EUR 158 million of profit in the first nine months of 2024).

The table below shows the effect, at 30 September 2025 and 31 December 2024, 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:
