	General background

Group financial information

General background

In H1 2024, Santander operated in an environment characterized by a gentle global economic slowdown, with relatively stable interest rates and a gradual decline in inflation in most regions. Geopolitical tensions, while still present, have not resulted in significant economic impacts. Labour markets withstood the monetary tightening period, with unemployment rates at or close to full employment across most of Santander's footprint.

Country		GDP Change1	Economic performance
	Eurozone	+0.4%	Having stagnated in 2023, the economy has entered a phase of soft recovery driven by external demand. Inflation continued to moderate (+2.5% year-on-year in June), which allowed for a 25 bp interest rate cut in June. The ECB is expected to make further interest rate cuts in the second half of the year, but it will depend on whether inflation continues to approach the ECB's target.
	Spain	+2.5%	In Q1 2024, GDP grew 2.5% year-on-year, supported by strong exports of services, while investment remained below pre-pandemic levels. The labour market remains strong, with the number of people enrolled in social security at record levels. In June, inflation was rose 3.4% year-on-year, while core inflation remained at 3%, due to persistently high inflation in services sector.
	United Kingdom	+0.3%	The economy grew in Q1 2024, ending the technical recession that began in H2 2023. The outlook has also improved, with increased business and consumer confidence and real wage growth. The unemployment rate remained low, although it increased to 4.4% in April. Inflation continues to decline (2.0% year-on-year in June) due to lower food prices. Inflationary pressures on wages and services led the Bank of England to hold the official interest rate at 5.25%.
	Portugal	+1.5%	Growth in Q1 2024 surprised positively due to the contribution from external demand. On the other hand, the contribution from domestic demand decreased, due to the slowdown in investment and private consumption. Labour market data remained strong with employment rising and unemployment at low levels (6.5% in May). After moderating in recent months, inflation rose slightly in June (2.8% year-on-year).
	Poland	+2.0%	In Q1 2024, GDP rose supported by private consumption. Supply constraints in the labour market and resilient labour demand kept the unemployment rate low (4.9% in June), supporting higher wages (+11.4% year-on-year in May). Inflation is within the central bank’s target range (2.6% year-on-year in June). However, core inflation remained high (+3.8% year-on-year in May) and, as such, the central bank decided to hold interest rates at 5.75%.
	United States	+2.9%	Domestic demand grew at a good pace in Q1 2024, but private consumption showed signs of slowdown in Q2 2024. The unemployment rate rose to 4.1% in June. Inflation, which had increased in Q1 2024, has since declined (3.0% year-on-year in June).
	Mexico	+1.6%	After having started the year with slight growth, the economy is now showing signs of weakening, though the labour market remains resilient. Year-on-year inflation rebounded to 5.0% in June. After a first 25 bp interest rate cut in Q1 2024, the central bank held interest rates at 11% in Q2 2024.
	Brazil	+2.5%	The economy recovered dynamism in early 2024, driven by private consumption, investment and a strong labour market. Year-on-year inflation rebounded to 4.2% in June and medium-term expectations rose, moving away from the target. Following the latest interest rate cut in May (-25 bps to 10.5%), the central bank held interest rates in June.
	Chile	+2.3%	After a weak 2023, the economy is recovering with growth in mining, industry and services sectors. Inflation rose slightly to 4.2% year-on-year in June. The central bank continued its process of rapid interest rate cuts, with a 150 bp reduction in Q2 2024 to 5.75%, though it said that interest rate cuts will slow down.
	Argentina	-5.1%	The economy remained weak at the beginning of the year, due to the impact of the fiscal and monetary adjustments and high inflation, although inflation has moderated faster than expected as the year has progressed (down to a monthly average of 5.9% during Q2 2024). The external sector is showing signs of recovery, with increases in exports and trade surpluses, in contrast to the 2023 deficit.

	Highlights of the period

Highlights of the period

Main figures
	u	In Q2 2024, profit attributable to the parent was EUR 3,207 million, a new record quarter, despite charges totalling EUR 452 million (provisions relating to our CHF mortgage portfolio in Poland and write-downs after discontinuing our merchant platform in Germany and Superdigital in Latin America).
	u	Attributable profit was 12% higher compared to Q1 2024 (+13% in constant euros), mainly driven by the good performance in Retail, Consumer and Wealth, and after having recorded the temporary levy on revenue obtained in Spain in Q1 2024 and the aforementioned charges in Q2 2024.
	u	Attributable profit increased 20% (in both euros and constant euros) compared to Q2 2023, with Retail, Wealth and Consumer growing. No contribution to the Single Resolution Fund (SRF) has been recorded in 2024, as contributions ended in 2023.
	u	In H1 2024, attributable profit was EUR 6,059 million, 16% higher than in the same period of 2023 (+15% in constant euros) boosted by solid revenue growth across all global businesses and regions.
	u	These positive results enabled us to improve the targets we had set for the year in revenue (from mid-single digit growth to high-single digit growth), efficiency (from less than 43% to close to 42%) and profitability (from 16% RoTE to more than 16%), while maintaining our objectives in capital and cost of risk.
	u	Profitability improved year-on-year and quarter-on-quarter. RoTE stood at 15.9% in H1 2024, compared to 14.5% in the same period of 2023. Annualizing the impact of the temporary levy on revenue obtained in Spain, RoTE was 16.3%, boosted by strong revenue growth.
	u	Sustained earnings per share growth in H1 2024, which rose 19% compared to H1 2023 to EUR 36.7 cents, supported by the positive performance in results and the share buybacks in the last 12 months.
	u	Business volumes continued to reflect the impact that the economic and interest rate environment had on customer behaviour and our active and disciplined capital management. Gross loans and advances to customers (excluding reverse repos) increased 2% year-on-year in constant euros, with all businesses growing except Retail, which decreased slightly as higher volumes in South America and Mexico largely offset lower loans in Europe and the US. Customer funds (customer deposits excluding repurchase agreements plus mutual funds) rose 5% year-on-year in constant euros, with deposits growing across all businesses except CIB (lower volumes in Spain and the US), while mutual funds rose double digits.
	u	The benefits from our global scale, margin management and higher customer activity were reflected in year-on-year increases in net interest income (+12% in euros, +11% in constant euros) and net fee income (+6% both in euros and constant euros), resulting in total income growth of 10% in euros (+9% in constant euros).
	u	Structural changes towards a simpler and more integrated model through ONE Transformation are contributing to efficiency gains and profitable growth. The efficiency ratio improved 2.6 pp compared to H1 2023 to 41.6%, driven mainly by Retail and Consumer.
	u	Credit quality remains robust, driven by the strong macroeconomic environment and employment across our footprint. The NPL ratio was 3.02%, improving 5 bps year-on-year. Total loan-loss reserves reached EUR 23,323 million, resulting in a total coverage ratio of 66%.
	u	The Group's cost of risk stood at 1.21% (1.18% in December 2023 and 1.08% in June 2023), in line with our expectations. Retail and Consumer accounted for 85% of Group's net loan-loss provisions. In Retail, the cost of risk remained under control at 1.03%. In Consumer, CoR continued to normalize (to 2.17%) and remained at controlled levels and in line with expectations.
	u	As at end June 2024, the fully-loaded CET1 ratio stood at 12.5%. In the quarter, we generated 52 bps organically, including a 7 bp positive contribution from RWAs, as RWA growth was more than offset by significant risk transfer and asset rotation initiatives. We also recorded a 25 bp charge for shareholder remuneration against profit earned in Q2 2024 in line with our 50% payout target1. Additionally, we recorded charges of -7 bps relating to deductions, mainly intangible assets and held to collect and sell portfolio valuations. There were no significant regulatory charges in the quarter.

1.In line with the current shareholder remuneration policy of approximately 50% of the Group's reported profit (excluding non-cash, non-capital ratios impact items), divided approximately equally between cash dividends and share repurchases. Execution of the shareholder remuneration policy is subject to future corporate and regulatory decisions and approvals.

January - June 2024 7

Key consolidated data Business model	Group financial information	Financial information by segment	Responsible banking Corporate governance Santander share	Appendix	Index
	Highlights of the period

Think Value

	u	The AGM approved a cash dividend of EUR 9.50 cents per share that was paid in May. Including the cash dividend per share paid in November 2023 (EUR 8.10 cents), the total cash dividend per share paid against 2023 results was EUR 17.60 cents, around 50% more than the dividends per share paid against 2022 results.
	u	In addition to this payment, there were two share buyback programmes which have been completed for a total of EUR 2,769 million. Including purchases made under such buyback programmes, the Group has repurchased c.11% of its outstanding shares since we began our buybacks in 2021.
	u	Total shareholder remuneration against 2023 results totalled EUR 5,552 million, 45% higher than the remuneration against 2022 results, distributed approximately equally between cash dividends and share buybacks.
	u	As at end June 2024, TNAV per share was EUR 4.94. Including both cash dividends charged against 2023 results, the TNAV per share + cash dividend per share increased 12% year-on-year.

Think Customer

	u	Our efforts to simplify and improve our product offering and quality of service were reflected in a more than 4 million year-on-year increase in total customers to 168 million, while active customers reached 101 million, up almost 2 million year-on-year.
	u	Transaction volumes per active customer rose 9% year-on-year in H1 2024.
	u	We continue to deliver great customer experience and improve our service quality, ranking in the top 3 in NPS1 in seven of our markets.

Think Global

	Contribution to Group revenue2		Year-on-year changes in constant euros
		u	In Retail, attributable profit was EUR 3,326 million (+35%) driven by double-digit growth in total income and the good performance in costs (due to our transformation efforts) and provisions.
		u	Efficiency improved 4.8 pp to 39.5%, cost of risk remained controlled (1.03%) and RoTE increased to 17.4% (18.1% annualizing the impact of the temporary levy).
		u	In Consumer, net operating income increased 12%, supported by total income growth (+7%) and good cost management, reaching an attributable profit of EUR 1,070 million, (+4%) despite higher LLPs (CHF mortgages, cost of risk normalization, higher volumes and some regulatory impacts).
		u	Efficiency stood at 40.6%, improving 2.7 pp, cost of risk was 2.17% and RoTE stood at 12.8% (13.0% annualizing the impact of the temporary levy).
		u	In CIB, revenue continued to grow, reaching record figures for H1 2024. However, attributable profit (EUR 1,405 million), declined 5%, impacted by costs relating to our transformation investments and lower gains on financial transactions in Brazil.
		u	The efficiency ratio was 43.4%, remaining one the best in the sector. RoTE was 19.0% (19.1% annualizing the impact of the temporary levy).
		u	In Wealth, attributable profit amounted to EUR 818 million (+14%) driven by higher activity and margin management, boosted especially by Private Banking.
		u	Efficiency improved 2.3 pp to 34.4% and RoTE was 79.3% (80.4% annualizing the impact of the temporary levy).
		u	In Payments, attributable profit reached EUR 49 million, impacted by write-downs in PagoNxt related to the discontinuation of our merchant platform in Germany and Superdigital in Latin America. Excluding it, profit would be 30% higher than in H1 2023, due to revenue growth and lower LLPs.
		u	Cost of risk slightly improved 8 bps to 7.03%. In PagoNxt, EBITDA margin was 20.1% (+8.9 pp year-on-year).

Statutory income statement

Results performance compared to H1 2023

In Q2 2024, profit attributable to the parent totalled EUR 3,207 million, reaching a new quarterly record, despite incorporating charges of EUR 452 million net of tax and minority interests: EUR 209 million related to higher provisions for our CHF mortgage portfolio in Poland (in Retail and Consumer), which brings the current ratio of these on-balance sheet assets to provisions to 100%; and EUR 243 million from write-downs in PagoNxt related to the discontinuation of our merchant platform in Germany (to focus on our core markets) and Superdigital in Latin America (in line with our strategy to promote the use of our common platforms across the Group to maximize operational leverage and provide the best service, while increasing access to banking services in the mass segment).

Additionally, from Q2 2024 onwards, a theoretical exchange rate has been used for the Argentine peso. For further information, see the 'Alternative performance measures' section in the appendix to this report.

Profit attributable to the parent amounted to EUR 6,059 million in H1 2024, compared to EUR 5,241 million in the same period in 2023, 16% higher year-on-year. This increase is due to the good performance of total income, which grew at a much faster pace than operating expenses, and with provisions growing in line with expectations, driven by the normalization in our Consumer business. SRF contributions ended in 2023 and therefore there is no contribution in 2024.

Total income

Total income amounted to EUR 30,715 million, up 10% year-on-year. By line:

•Net interest income (NII) totalled EUR 23,457 million, 12% higher than in H1 2023 with widespread growth across businesses and regions.

Growth was driven by Retail in Europe, due to good price management, and greater volumes and good margin management in Retail in Brazil and Consumer, benefitting from a lower interest rate environment given the negative sensitivity of its balance sheet. NII was also backed by increased activity in CIB, Wealth and Payments.

Net interest income

EUR million

•Net fee income amounted to EUR 6,477 million, up 6% compared to H1 2023, with solid performance across all our businesses, except Payments which was impacted by a one-time positive fee recorded in Q1 2023.

Net fee income

EUR million

•Gains or losses on financial assets and liabilities and exchange differences declined to EUR 957 million (EUR 1,302 million in H1 2023) affected by lower results in CIB, mainly in Brazil in a weak market.

•Dividend income was EUR 493 million (EUR 382 million in H1 2023).

•Income from companies accounted for by the equity method reached EUR 303 million, compared to EUR 296 million in H1 2023.

•Other operating income recorded a loss of EUR 972 million (compared to a EUR 993 million loss in H1 2023), owing to the negative impact from hyperinflation adjustment in Argentina (EUR 687 million), and the temporary levy on revenue earned in Spain (EUR 335 million in Q1 2024 and EUR 224 million in Q1 2023). As mentioned above, no contributions to the SRF were charged in 2024 (EUR 293 million in Q2 2023).

Total income

EUR million

All in all, good performance of total income, supported by year-on-year growth across all our businesses and regions.

Operating expenses

Operating expenses in H1 2024 amounted to EUR 12,913 million, and rose 3% year-on-year (at a much slower pace than total income), mainly due to the impact of inflation.

Our cost management continued to focus on structurally improving our efficiency and, as a result, we remained among the most efficient banks in the world.

We continued to drive our business transformation plan, ONE Transformation, across our footprint, reflected in greater operational leverage and better business dynamics.

Operating expenses

EUR million

Provisions or reversal of provisions

Provisions (net of provisions reversals) amounted to EUR 1,762 million and included a write-down in PagoNxt related to the discontinuation of our Superdigital platform in Latin America. In H1 2023, this provisions totalled EUR 1,330 million.

Impairment or reversal of impairment of financial assets not measured at fair value through profit or loss (net)

Impairment or reversal of impairment on financial assets not measured at fair value through profit or loss (net) was EUR 6,577 million (EUR 6,237 million in H1 2023), driven by volumes growth, normalization and regulatory impacts in Consumer. It also includes provisions for our CHF mortgage portfolio in Poland, both in H1 2024 and H1 2023.

Credit quality indicators remained robust, supported by the good performance of the global economy and labour markets across our footprint.

Impairment on other assets (net)

The impairment on other assets (net) was EUR 290 million, including the write-down in PagoNxt related to the discontinuation of our merchant platform in Germany. In H1 2023, impairments totalled EUR 92 million.

Gains or losses on non-financial assets and investments (net)

Net gains on non-financial assets and investments were EUR 366 million in H1 2024, including a EUR 352 million capital gain resulting from having closed the joint-venture agreement with Sodexo in Brazil. In H1 2023 net gains were EUR 277 million .

Negative goodwill recognized in results

There was no negative goodwill recorded in H1 2024 or in H1 2023.

Gains or losses on non-current assets held for sale not classified as discontinued operations

This item, which mainly includes impairment of foreclosed assets recorded and the sale of properties acquired upon foreclosure, recorded a EUR 31 million loss in H1 2024 (EUR 59 million loss in H1 2023).

Profit before tax

Profit before tax was EUR 9,508 million in H1 2024, up 18% year-on-year, supported by the solid performance in net interest income and net fee income.

Income tax

Total income tax amounted to EUR 2,916 million compared to EUR 2,281 million in H1 2023.

Profit attributable to non-controlling interests

Profit attributable to non-controlling interests amounted to EUR 533 million (EUR 568 million in H1 2023).

Profit attributable to the parent

Profit attributable to the parent rose to EUR 6,059 million in H1 2024, compared to EUR 5,241 million in the same period in 2023, 16% higher year-on-year.

These results do not fully reflect the underlying business performance due to the impact of the aforementioned charges.

Results performance compared to H1 2023

The Group presents, both at the total Group level and for each of the business units, the changes in euros registered in the income statement, as well as variations excluding the exchange rate effect (i.e. in constant euros) except for Argentina and any grouping which includes it, understanding that the latter provide a better analysis of the Group’s management. Additionally, from Q2 2024 onwards, a theoretical exchange rate has been used for the Argentine peso. For further information, see the 'Alternative performance measures' section in the appendix to this report.

At the Group level, exchange rates had a positive impact of 0.7 pp in revenue and a negative impact of 0.5 pp in costs.

To better understand the business trends, we reclassified certain items under some headings of the underlying income statement. These items explain the differences between the statutory and underlying income statements and are:

•In H1 2024:

–The impact of the temporary levy on revenue earned in Spain totalling EUR 335 million in Q1 2024, which was moved from total income to other gains (losses) and provisions.

–Provisions which strengthen the balance sheet in Brazil of EUR 352 million in Q2 2024 (EUR 174 million net of tax and minority interests).

•In H1 2023:

–The impact of the temporary levy on revenue earned in Spain totalling EUR 224 million in Q1 2023, which was moved from total income to other gains (losses) and provisions.

–Provisions which strengthen the balance sheet in Brazil of EUR 235 million, net of tax and minority interests in Q1 2023.

For more details, see the 'Alternative Performance Measures' section in the appendix of this report.

As profit was not affected by results that fell outside the ordinary course of our business, no amount was recorded in the net capital gains and provisions line in H1 2024 or in H1 2023 and so both profit attributable to the parent and underlying profit were the same; EUR 6,059 million in H1 2024 and EUR 5,241 million in H1 2023. This represents a 16% year-on-year increase, a 15% rise in constant euros.

This year-on-year comparison is impacted by a higher charge of the temporary levy and by the EUR 243 million net of tax and minority interests from the write-downs in PagoNxt in Q2 2024 related to the discontinuation of our merchant platform in Germany and Superdigital in Latin America. Additionally, there was no contribution to the SRF in 2024, as contributions ended in 2023.

Total income amounted to EUR 31,050 million, a new record, up 10% year-on-year. In constant euros, total income rose 9% year-on-year, as follows:

•Net interest income (NII) was 11% higher than H1 2023 with growth across businesses and regions:

–Strong growth in Retail, (+12%) with increases in all regions, especially in Europe, driven by good liability margin management, and in South America which benefitted from higher volumes and lower deposit costs in Brazil and Chile following interest rate cuts.

–In Consumer, NII rose 7% supported by our active asset repricing actions and volumes growth in Europe, and higher volumes and lower interest rates in Brazil (favouring consumption).

–CIB increased strongly (+22%), backed by solid performance in Global Banking.

–In Wealth, NII rose 13%, driven by good margin management and increased activity in Private Banking in a favourable macroeconomic environment.

–In Payments, NII rose 10% driven by the solid performance in Cards, which is the main NII business in Payments, driven by higher volumes in Mexico and Brazil.

•Net fee income grew 6% compared with H1 2023, reaching a new record of EUR 6,477 million with widespread growth across all businesses except Payments, whose year-on-year comparison was impacted by a one-time positive fee from commercial agreements in Brazil in Q1 2023. By business:

–In Retail, net fee income increased 3%, supported by growth across most countries, especially in Brazil, mainly due to insurance and foreign exchange fees.

–In Consumer, net fee income rose 27%, driven by growth in Europe due to increased insurance penetration (particularly in Germany), in Brazil boosted by volumes growth, and in the US in part due to auto fees.

–In CIB, it increased 12%, driven by greater activity in Global Banking, backed by our US Banking Build-Out (BBO) initiatives.

–In Wealth, net fee income rose 15%, mainly due to the good commercial activity in Private Banking and Asset Management.

–In Payments, it declined 7% affected by the impact of the aforementioned one-time positive fee in Q1 2023 in Cards,

while net fee income rose in PagoNxt due to the good performance in Ebury and the increase in Getnet in Chile, Mexico and Europe.

•Gains on financial transactions declined 26% driven by CIB (lower gains in Global Markets down from a very strong H1 2023, especially by Brazil in a weak market, partially offset by higher results in Retail.

•Other operating income included a greater negative impact from hyperinflation adjustment in Argentina. In 2024, there is no contribution to the SRF, as contributions ended in 2023.

This positive performance in revenue during H1 2024, enabled us to improve growth expectations for the whole year and upgrade our total income target from mid-single digit growth to high-single digits.

•Administrative expenses and amortizations in H1 2024 totalled EUR 12,913 million, up 3% year-on-year. In real terms, excluding the impact of the average inflation, and in constant euros, they were 1% lower year-on-year.

Our cost management continued to focus on structurally improving our efficiency. As a result, we remained among the most efficient banks in the world with an efficiency of 41.6%, having improved 2.6 pp vs. H1 2023 and better than our target for 2024. This is why we have upgraded our efficiency ratio target from under 43% to close to 42%.

We continued to progress with our business transformation plan, ONE Transformation, reflected in greater operational leverage and better business dynamics. By business and in constant euros:

Key consolidated data Business model	Group financial information	Financial information by segment	Responsible banking Corporate governance Santander share	Appendix	Index
	Underlying income statement

–In Retail, costs remained flat, but were down 4% in real terms (i.e excluding inflation), driven by the efforts in transformation (mainly in Spain and the US) and the lower costs in Argentina. The efficiency ratio stood at 39.5%, improving 4.8 pp year-on-year.

–In Consumer, costs were stable year-on-year, in real terms they fell 3% driven by cost discipline in the US, absorbing strategic investments in platforms in leasing (launched in two European markets) and check-out lending. This resulted in a 2.7 pp improvement in the efficiency ratio year-on-year, falling to 40.6%.

–In CIB, they increased by 20%, +16% in real terms, due to our investments in new products and capabilities, as we invest for future growth. The efficiency ratio stood at 43.4%.

–In Wealth, costs rose 5% mainly due to inflation. In real terms, they increased 2% due to investments in key initiatives such as reinforcing our Private Banking teams to respond to higher commercial activity. The efficiency ratio improved 2.3 pp year-on-year to 34.4%.

–In Payments, they were 4% up impacted by inflationary pressures, as they were flat in real terms despite investments in global platforms in both PagoNxt and Cards. The efficiency ratio remained relatively stable year-on-year at 46.9%.

•Net loan-loss provisions in H1 2024 amounted to EUR 6,243 million, up 8%. In constant euros, they also increased 8%, as the good performance in Retail, due to lower levels of provisions in Europe, partially offset the expected increase in Consumer, driven by the normalization of the cost of risk from very low levels, volumes growth and regulatory impacts.

Additionally, we increased the coverage of the CHF mortgage portfolio in Poland. The cost of risk stood at 1.21%, in line with the Group’s target for 2024.

•Profit attributable to the parent in H1 2024 was EUR 6,059 million, 16% more than in the same period in 2023 (+15% in constant euros), supported by double-digit net operating income growth, as total income greatly outpaced cost growth.

Annualizing the impact of the temporary levy on revenue earned in Spain, RoTE in H1 2024 would have been 16.3%. Positive H1 2024 results enabled us to improve our profitability target for the year, from a 16% RoTE to more than 16%.

Underlying results performance compared to Q1 2024

Underlying profit attributable to the parent and profit attributable to the parent were the same both in Q2 2024, at EUR 3,207 million, and in Q1 2024, at EUR 2,852 million, as profit was not affected by results outside the ordinary course of our business.

Quarterly variations in the income statement are impacted by the application of the new theoretical exchange rate for the Argentine peso. For further information, see the 'Alternative performance measures' section in the appendix to this report.

Profit increased 12% compared to Q1 2024. In constant euros, it increased 13%, by line:

Total income rose 3% driven by the positive performance of the main lines:

•Net interest income decreased 4%, largely impacted by Argentina. Excluding Argentina, it rose 2% driven by Retail (mainly Brazil and Chile supported by lower cost of deposits and greater volumes) and the increased activity in CIB.

•Net fee income grew 1% quarter-on-quarter. Excluding Argentina, they rose 3%, backed by the good performances in Retail, Consumer and Payments.

•Gains on financial transactions fell 46% (-42% excluding Argentina), due to the performance in CIB, mainly in Brazil, partially offset by higher results in Retail and the Corporate Centre.

•Operating expenses in Q2 2024 fell 2% quarter-on-quarter. Excluding Argentina, they were flat as cost efficiencies captured in Retail were offset by our investments in CIB.

•Net loan-loss provisions were practically flat, as the significant declines in Consumer in the US and Brazil offset the increase in Retail, due to volumes growth, and higher CHF provisions in Poland (Retail and Consumer).

•Other gains (losses) and provisions had a EUR 1,261 million loss in Q2 2024, which includes the write-downs in PagoNxt related to the discontinuation of our merchant platform in Germany and Superdigital in Latin America, compared to a EUR 1,125 million loss recorded in Q1 2024, which was affected by the impact of the temporary tax on revenue earned in Spain.

Loans and advances to customers

Loans and advances to customers stood at EUR 1,065,596 million as at end June 2024, a 2% increase both year-on-year and quarter-on-quarter.

For the purpose of analysing traditional banking loans, the Group uses gross loans and advances to customers excluding reverse repos (EUR 1,027,346 million). Additionally, the comments below do not include the exchange rate impact (i.e in constant euros), except for Argentina and any grouping which includes it. From Q2 2024 onwards, a theoretical exchange rate has been used for the Argentine peso. For further information, see the 'Alternative performance measures' section in the appendix to this report. However, the use of this new exchange rate did not significantly impact quarter-on-quarter balance variations given the small size of Argentina’s balance sheet relative to the total Group.

In Q2 2024, gross loans and advances to customers, excluding reverse repos, rose 2% quarter-on-quarter in constant euros, as follows:

•They increased 1% in Retail, driven by growth in corporates, as individuals and SMEs were stable. By region, they increased in South America (mainly in Brazil), North America (mainly Mexico) and were flat in Europe (good performance in Spain and Poland offset the fall in the UK).

•In Consumer, loans grew 3%, driven by the increases in auto in Europe, the US and Brazil.

Compared to June 2023, gross loans and advances to customers (excluding reverse repos and in constant euros) grew 2%, as follows:

•In Retail, they dropped 1%, as falls in the UK (in line with our strategy of increasing profitability) and Spain (affected by mortgage prepayments and lower SME lending) was partially offset by growth in Brazil, Poland, Mexico and Chile.

•They rose 6% in Consumer, boosted by the good performance in auto in Europe and Brazil.

•In CIB, they grew 7% boosted by solid growth in the US, on the back of our US BBO initiatives.

•They increased 3% in Wealth and 4% in Payments.

As at end June 2024, gross loans and advances to customers excluding reverse repos maintained a diversified mix among the markets in which the Group operates: Europe (55%), DCB Europe (14%), North America (16%) and South America (15%).

Customer funds

Customer deposits amounted to EUR 1,037,646 million in June 2024, falling 1% quarter-on-quarter and growing 2% year-on-year.

The Group uses customer funds (customer deposits excluding repos, plus mutual funds) for the purpose of analysing traditional retail banking funds, which amounted to EUR 1,171,085 million as at end June 2024. Additionally, the comments below do not include the exchange rate impact (i.e in constant euros), except for Argentina and any grouping which includes it. From Q2 2024 onwards, a theoretical exchange rate has been used for the Argentine peso. For further information, see the 'Alternative performance measures' section in the appendix to this report. However, the use of this new exchange rate did not significantly impact quarter-on-quarter balance variations given the small size of Argentina’s balance sheet relative to the total Group.

In the quarter, customer funds were flat in constant euros, as follows:

•By product, customer deposits excluding repos decreased slightly, offset by mutual funds which grew 3%.

•By primary segment, customer funds grew 3% in Consumer, up 1% in Retail and Wealth. On the other hand, they fell 7% in CIB, mainly driven by strategy changes to reduce excess corporate deposits.

Compared to June 2023, customer funds were up 5% in constant euros:

•By product, deposits excluding repurchase agreements rose 2%, driven by an increase in time deposits (+12%) given the current interest rate environment, with time deposit growth in most markets (except in the US and Argentina), to the detriment of demand deposits, which fell 1%. Mutual funds increased 17%.

•By business, they rose 4% in Retail, backed by strong growth in Brazil, Spain, Mexico and Poland, up 14% in Consumer as part of our strategy to increase deposit funding, while they fell 3% in CIB due to lower volumes in Spain and the US, and increased 10% in Wealth, due to mutual funds.

•By secondary segment, strong growth in Brazil, Spain Mexico, Poland and DCB Europe.

As at June 2024, customer funds maintained a diversified mix among the markets in which the Group operates: Europe (62%), DCB Europe (7%), North America (14%) and South America (17%). The weight of demand deposits as a percentage of total customer funds was 56%, while time deposits accounted for 25% of the total and mutual funds for 19%.

In addition to capturing customer deposits, the Group, for strategic reasons, maintains a selective policy of issuing securities in the international fixed income markets and strives to adapt the frequency and volume of its market operations to the structural liquidity needs of each unit, as well as to the receptiveness of each market.

In H1 2024, the Group issued:

•Medium- and long-term senior debt placed in the market of EUR 12,053 million and covered bonds amounting to EUR 6,272 million.

•TLAC eligible instruments issued amounted to EUR 11,998 million, of which EUR 8,092 million was senior non-preferred, EUR 2,406 million was subordinated debt and EUR 1,500 million was AT1.

•Maturities of medium- and long-term debt totalled EUR 25,682 million.

The net loan-to-deposit ratio was 103% (103% in June 2023). The ratio of deposits plus medium- and long-term funding to the Group’s loans was 123%, underscoring the comfortable funding structure. The liquidity coverage ratio (LCR) was an estimated 163% in June 2024 (158% in June 2023).

The Group's access to wholesale funding markets and the cost of issuances depends, in part, on the ratings of the rating agencies.

Rating agencies
	Long term	Short term	Outlook
Fitch Ratings	A-(Senior A)	F2 (Senior F1)	Stable
Moody's	A2	P-1	Positive
Standard & Poor's	A+	A-1	Stable
DBRS	A (High)	R-1 (Middle)	Stable

Moody's confirmed its A2 long-term and P-1 short-term ratings in April of this year, and also improved its outlook from stable to positive following the same movement in the rating of the Kingdom of Spain, remaining two notches above sovereign. In April, Standard & Poor's (S&P) rated our additional tier 1 debt as BBB- (investment grade), a new rating for this instrument.

In terms of outlooks, DBRS and Fitch maintained their stable outlooks, above the sovereign's, while S&P also maintained its outlook but in line with the sovereign.

Sometimes the methodology applied by the agencies limits a bank's rating to the sovereign rating of the country where it is headquartered. Banco Santander, S.A. is still rated above the sovereign debt rating of the Kingdom of Spain by Moody’s, DBRS and S&P and at the same level by Fitch, which demonstrates our financial strength and diversification.

Executive summary

Fully-loaded capital ratio	Fully-loaded CET1 ratio
The fully-loaded CET1 ratio remained above 12% at the end of June, in line with the Group's objective.	We continued to generate capital organically in the quarter, backed by profit growth.
Fully-loaded CET1 performance (%)	Organic generation	+52 bps
	Accrual for shareholder remuneration1	-25 bps
	TNAV per share
	TNAV per share was EUR 4.94, increasing 12% year-on-year including the cash dividends.

As at end June 2024, the total phased-in capital ratio (applying the IFRS 9 transitional arrangements) stood at 16.7% and the phased-in CET1 ratio at 12.5%. We comfortably meet the levels required by the ECB on a consolidated basis (estimated 13.9% for the total capital ratio and 9.6% for the CET1 ratio)2. This resulted in a distance to the maximum distributable amount (MDA) of 245 bps and a CET1 management buffer of 286 bps.

In fully-loaded terms, we generated 52 bps organically in the quarter, including a 7 bp positive contribution from RWAs, as RWA growth was more than offset by significant risk transfer and asset rotation initiatives. We also recorded a 25 bp charge for shareholder remuneration against profit earned in Q2 2024 in line with our 50% payout target1.

Additionally, we recorded charges of -7 bps relating to deductions, mainly intangible assets and held to collect and sell portfolio valuations. There were no significant regulatory charges in the quarter.

This resulted in a fully-loaded CET1 ratio of 12.5%. The total fully-loaded capital ratio stood at 16.4%.

TNAV per share ended the quarter at EUR 4.94. Including the cash dividend paid in November 2023 (EUR 8.10 cents) and the second cash dividend charged against 2023 results (EUR 9.50 cents) paid in May, TNAV plus cash dividend per share increased 12% in the last twelve months (+2% in the quarter).

Lastly, the fully-loaded leverage ratio stood at 4.74% and the phased-in was also 4.74%.

1.Shareholder remuneration charged against profit earned in Q2 2024 in line with our target of approximately 50% payout, divided approximately equally between cash dividends and share repurchases. The implementation of the shareholder remuneration policy is subject to future corporate and regulatory decisions and approvals.

2.On 1 January 2024, our systemic buffer requirement increased from 1% to 1.25% due to a higher D-SIB requirement due to i) a methodological change by the ECB which was later adopted by Banco de España and ii) because institutions must hold capital at the consolidated level for the higher of the G-SIB (currently at 1%) and D-SIB requirements. Additionally, the ECB revised Banco Santander, S.A.'s P2R requirement from 1.58% to 1.74%, mainly due to a change in the ECB's methodology.

Credit risk 1

During H1 2024, one of the main factors influencing market behaviour was the uncertainly around the decline of inflation, where the ECB recently cut interest rates slightly while the Federal Reserve and the Bank of England held rates. Other determining factors were the growing geopolitical tensions and the various electoral processes in Europe and Latin America.

Nevertheless, in the current soft-landing scenario with a slight slowdown in inflation, economic activity has not been significantly affected, partially due to strong labour markets and fiscal policies that have been supportive of households and businesses.

Our business model, together with our conservative risk management, help us to maintain a medium-low risk profile even in a less favourable macroeconomic and geopolitical environment.

In terms of credit quality:

•The NPL ratio stood at 3.02% (-8 bps compared to Q1 2024), mainly driven by higher gross credit risk with customers (total risk), that increased 2% quarter-on-quarter, reaching EUR 1,164 billion, while credit impaired loans remained stable in the quarter at EUR 35,091 million, due to the good performance in Retail.

•Net loan-loss provisions rose 8% year-on-year in H1 2024 to EUR 6,243 million, due to the expected normalization in Consumer and increases in Retail in Mexico and Brazil, partially offset by lower levels of provisions in the European Retail portfolio.

In the quarter, provisions slightly increased (+1%), as lower provisions in the Consumer portfolio in the US offset higher provisions in CHF mortgage portfolio.

The cost of risk was 1.21%, remaining in line with our target for the year, in a context of a slight increase in credit risk exposure in the last 12 months.

•The total coverage ratio for credit impaired loans remained flat in the quarter at 66%, with loan-loss allowances of EUR 23,323 million. The coverage ratio remained at comfortable levels considering that 68% of the Group’s portfolio backed by quality collateral.

The IFRS 9 stage distribution of the portfolio was largely unchanged in the quarter in percentage terms. Stage 2 balances increased slightly due to changes in the classification criteria, improving our early risk detection systems. It does not significantly affect the total loan-loss provisions.

Stage 1: financial instruments for which no significant increase in credit risk has been identified since its initial recognition.

Stage 2: if there has been a significant increase in credit risk since the date of initial recognition but the impairment event has not materialized, the financial instrument is classified in Stage 2.

Stage 3: a financial instrument is catalogued in this stage when it shows effective signs of impairment as a result of one or more events that have already occurred resulting in a loss.

Our Retail, Consumer, CIB and Payments businesses account for more than 95% of the Group's total portfolio. The performance of the main businesses in Q2 2024 was as follows:

	Retail & Commercial Banking	Credit risk exposure
		56% of total Group

Retail's portfolio mainly comprises high quality mortgage loans, where 90% of loans have an LTV lower than 80%, and a corporate portfolio in which more than 50% have property collateral or other collateral.

The NPL ratio dropped 9 bps in the quarter to 3.15%, driven by the decrease in credit impaired loans, mainly in Europe. On the other hand, gross credit risk with customers (total risk) remained practically flat in the quarter.

Net loan-loss provisions declined 1% year-on-year, mainly due to the positive performance of the European portfolios. Provisions rose 5% quarter-on-quarter, driven by the increases in Brazil and in the CHF mortgage portfolio in Poland.

The cost of risk stood at 1.03%, having increased 11 bps year-on-year and remaining stable in the quarter.

The total coverage ratio of credit impaired loans was stable quarter-on-quarter at 60%. Given the Retail portfolio includes the mortgage portfolios in Spain and the UK, which have high-quality collateral, we consider the coverage is at appropriate levels for the risk of the portfolio.

	Digital Consumer Bank	Credit risk exposure
		18% of total Group

The Consumer portfolio mainly comprises auto loans (representing around 80% of the portfolio) through strategic alliances and our leasing business, as well as personal loans with good credit quality.

The NPL ratio stood at 4.81%, improving 5 bps quarter-on-quarter. Gross credit risk with customers (total risk) growth compensated the slight increase in credit impaired loans, which stood at EUR 10,280 million, 2% up in the quarter.

Net loan-loss provisions increased 21% year-on-year, affected by the continued normalization in Europe and the US (but still below our historical average). In the quarter, they improved 7% due to lower provisions in the US and Brazil.

The cost of risk stood at 2.17%, +31 bps quarter-on-quarter, performing as expected.

The total coverage ratio of credit impaired loans remained stable in the quarter and stood at 76%, a level we are comfortable with, considering more than 80% of the portfolio is auto loans.

	Corporate & Investment Banking	Credit risk exposure
		21% of total Group

CIB's portfolio consists of high credit quality wholesale customers (more than 85% of which have a rating above investment grade), with a strong advisory component and high value-added solutions.

The NPL ratio decreased 9 bps in the quarter to 1.05%, due to the portfolio increases (+5%), mainly in Spain, Poland and North America (supported by business growth in the CIB franchise in the US).

Net loan-loss provisions stood at EUR 96 million versus EUR 7 million in H1 2023 (net releases in Q1 2023). Compared to Q1 2024, they increased EUR 15 million.

The cost of risk was stable in the quarter at 0.15%.

The total coverage ratio of credit impaired loans declined 1 pp in the quarter to 45%, a level we believe to be adequate considering the credit quality of the portfolio.

	Payments	Credit risk exposure
		2% of total Group

Payments has a portfolio characterized by a high rapid turnover and high returns that offset its level of risk.

The NPL ratio stood at 5.00% (+15 bps vs. Q1 2024), due to the 2% increase in impaired loans in Cards, mainly in Europe and Brazil. Gross credit risk with customers decreased slightly in the quarter due to PagoNxt.

Net loan-loss provisions, which are mainly concentrated in the Cards portfolio, fell 3% year-on-year, but picked up 6% compared to Q1 2024, mainly driven by Brazil and the UK, partially offset by the decrease in Mexico.

The cost of risk rose to 7.03%.

The total coverage ratio of credit impaired assets stood at 149% having increased 5 pp in the quarter, remaining at levels we are comfortable with.

Market risk

Markets continue to be conditioned by central banks' monetary policies as well as by geopolitical tensions. Additionally, the elections in Europe and in Mexico have also affected markets, and led to an increase in volatility in the Mexican peso, depreciating against the US dollar.

Stock markets continue to be supported by the resilience of the global economies, while market interest rates remain volatile, impacted by inflation expectations.

Global corporate banking trading activity is focused on serving the needs of our clients. Their risk is measured in terms of daily VaR at 99% and is mainly driven by possible movements in interest rates.

In Q2 2024, the average VaR reached a value of EUR 16 million (EUR 1 million lower than Q1 2024), remaining stable with some occasional bouts of volatility either due to markets or to a higher exposure mainly to interest rates.

By market risk factor, VaR continued to be driven mostly by interest rate risk. VaR figures remain low compared to the size of the Group's balance sheet and activity.

Trading portfolios1. VaR performance

EUR million

Structural and liquidity risk

Structural exchange rate risk: mainly driven by transactions in foreign currencies relating to permanent financial investments, their results and associated hedges. Our dynamic management of this risk seeks to limit the impact of foreign exchange rate movements on the CET1 ratio. In the quarter, hedging of currencies impacting this ratio remained close to 100%.

Structural interest rate risk: in Q2 2024, market interest rates showed high levels of volatility, conditioned by inflation trends and expectations for the possible monetary policy adjustments by the major central banks. Our structural debt portfolios continued to perform negatively, although our structural interest rate risk remained at comfortable levels during the period.

Liquidity risk: the Group maintained its comfortable liquidity risk position in the quarter, supported by a robust and diversified liquidity buffer, with ratios well above regulatory limits.

Operational risk

Our operational risk profile deteriorated slightly in Q2 2024. In terms of operational risk losses, there was an increase compared to Q1 2024. Legal proceedings and fraud continue to be the main drivers of these losses, which are concentrated in the Group's Retail business.

The Group continuously monitors the evolution of operational risks in general, and technological risk in particular, arising from transformation plans, the services provided by third parties, external fraud and the relevant judicial processes.

Regarding supplier risk and cyber risk, on 14 May 2024, we announced that we became aware of an unauthorized access to a Santander database hosted by a third-party provider. We immediately implemented measures to contain the incident, including blocking the compromised access to the database and establishing additional fraud prevention controls to protect affected customers.

Financial information by segment

Description of segments

As we previously announced, following the creation of two new global segments and in order to align the operating and management model, we adapted our reporting, starting with the financial information for Q1 2024, with global businesses becoming the primary segments.

Main changes to the composition of Santander's segments

The main changes, which apply from 1 January 2024 to the management information for all periods included in the consolidated financial statements, are as follows:

•All of the Group's businesses across all markets were consolidated into five global areas: Retail & Commercial Banking, Digital Consumer Bank, Corporate & Investment Banking, Wealth Management & Insurance and Payments. These became the new primary segments.

•The changes in financial information were:

–The former Retail Banking was split into two new segments: Retail & Commercial Banking and Digital Consumer Bank. Our cards business now forms part of the new Payments segment.

–The results of activities mainly related to financial management located in the countries are fully allocated to their global businesses based on the segment that generates the financial position.

–The local corporate centres are fully allocated to the global businesses.

–The revenue sharing criteria between global businesses were revised to better reflect the contribution of each business to the Group.

•The former primary segments (Europe, North America, South America and Digital Consumer Bank - which is renamed DCB Europe) became our secondary segments. 2023 published figures for the countries, regions and the Corporate Centre remain unchanged.

All the changes described above have no impact on the reported Group consolidated financial statements.

Composition of Santander's segments

Primary segments

This primary level of segmentation, which is based on the Group's management structure from 1 January 2024, comprises six reportable segments: five operating areas plus the Corporate Centre.

The operating areas are:

Retail & Commercial Banking (Retail): area that integrates the retail banking business and commercial banking (individuals, SMEs and corporates), except for business originated in the consumer finance and the cards businesses.

Digital Consumer Bank (Consumer): comprises all business originated in the consumer finance companies, plus Openbank, Open Digital Services (ODS) and SBNA Consumer.

Corporate & Investment Banking (CIB): this business, which includes Global Transaction Banking, Global Banking (Global Debt Financing 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.

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) and the insurance business (Santander Insurance).

Payments: the Group's digital payments solutions, providing global technology solutions for our 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 we operate).

Secondary segments

At this secondary level, Santander is structured into the segments that made up the primary segments until 2023, which are Europe, DCB Europe, North America and South America:

Europe: comprises all business activity carried out in the region, except that included in DCB Europe. Detailed financial information is provided on Spain, the UK, Portugal and Poland.

DCB Europe: includes Santander Consumer Finance, which incorporates the entire consumer finance business in Europe, Openbank in Spain and ODS.

North America: comprises all the business activities carried out in Mexico and the US, which includes the holding company (SHUSA) and the businesses of Santander Bank (SBNA), Santander Consumer USA (SC USA), the specialized business unit Banco Santander International, the New York branch and Santander US Capital Markets (SanCap).

South America: includes all the financial activities carried out by Santander through its banks and subsidiary banks in the region. Detailed information is provided on Brazil, Chile, Argentina, Uruguay, Peru and Colombia.

Appendix Index

In addition to these operating units, both at the primary and secondary segment level, the Group continues to maintain the area of the Corporate Centre, which includes the centralized activities relating to equity stakes in financial companies, financial management of the structural exchange rate position, assumed within the sphere of the Group’s assets and liabilities committee, as well as management of liquidity and of shareholders’ equity via issuances.

As the Group’s holding entity, this area manages all capital and reserves and allocations of capital and liquidity with the other businesses. It also incorporates goodwill impairment but not the costs related to the Group’s central services (charged to the areas), except for corporate and institutional expenses related to the Group’s functioning.

The businesses included in each of the segments in this report and the accounting principles under which their results are presented here may differ from the businesses included and accounting principles applied in the financial information separately prepared and disclosed by our subsidiaries (some of which are publicly listed) which in name or geographical description may seem to correspond to the business areas covered in this report. Accordingly, the results of operations and trends shown for our business areas in this document may differ materially from those of such subsidiaries.

As explained on the previous page, the results of our segments presented below are provided on the basis of underlying results only and include the impact of foreign exchange rate fluctuations. However, for a better understanding of the changes in the performance of our business areas, we also provide and discuss the year-on-year changes to our results excluding such exchange rate impacts (i.e. in constant euros), except for Argentina, and any grouping which includes it. Additionally, from Q2 2024 onwards, a theoretical exchange rate has been used for the Argentine peso. For further information, see methodology in the 'Alternative performance measures' section in the appendix to this report.

Certain figures contained in this report, have been subject to rounding to enhance their presentation. Accordingly, in certain instances, the sum of the numbers in a column or a row in tables contained in this report may not conform exactly to the total figure given for that column or row.

→ To support our vision of becoming a digital bank with branches, we continued to drive our ONE Transformation programme forwards with the implementation of a common operating model and the rollout of our global technological platform. → Loans decreased 1% year-on-year in constant euros due to lower mortgage and SME balances in Europe, partially offset by increases in South America and Mexico.

Strategy

In Q2 2024, we advanced in our strategic priorities:

•Implement a common operating model, leveraging the Group’s global scale and our local presence. Our vision is to make Santander into a digital bank with branches, offering all our products and services digitally through our own global platform and use our branch network to advise and help our customers.

•We have almost 143 million customers who can access most of our products and services digitally. Sales through our web and apps and digital customers continued to rise at a good pace.

•We have a network of more than 8,000 branches, present in 12 markets. Branches continued to strengthen their role as an essential driver of sales and advisory, reducing operational activities thereby increasing their focus on commercial functions and supporting customers.

•Continue our transformation efforts, based on three pillars:

•Customer experience. We reduced the number of products by 20% year-on-year, as part of our commitment to offer a simple and attractive product portfolio that provides the best experience for our customers. We also continued to innovate our catalogue of products and services through different initiatives. Of note in the quarter was the new simpler and competitive campaign in Brazil, which targets individuals, and complements our new digital and customer-oriented service model.

–Operational leverage. Year-on-year, we have reduced the number of resources dedicated to non-commercial activities

per million customers by 8% and resources dedicated to operational activities per million customers by 18%, supported by economies of scale, process automation and organization simplification. This has freed up time to focus on value added activities. Process digitalization and cash management optimization in branches are some examples of what we have achieved.

–Global Technology Platform. Our goal is to leverage the Group's scale and roll out a global platform. This platform is based on our back-end Gravity technology and on ODS’s in- house, cloud-based technology for our apps and websites.

In Q2 2024, we successfully implemented our Gravity platform in the US, which is also operative at the Group level in the UK, Spain, Mexico, Brazil and Chile. The volume of transactions running through Gravity continued to grow, increasing 20% year-on-year. Finally, the app is available in Spain, Portugal and Poland and we will launch it in the UK, Brazil and Colombia during the year.

•We continue to drive profitable growth and structural efficiency improvements. New digital processes to attract customers, a more targeted offer and enhanced customer experience drove further customer growth (+4% year-on-year). The efficiency which the global platform's scale provides, together with increased simplification and process automation were significant drivers of these results.

Business performance

Loans and advances to customers decreased 2% year-on-year. Excluding reverse repos and in constant euros, gross loans fell 1%, due to decreases in individuals and SMEs despite growth in corporates.

In individuals, mortgage balances fell both in the UK (in line with our strategy) and in Spain, still impacted by prepayments (but new business volumes are picking up). This was partially offset by increases in Poland, Brazil, Mexico and Chile. Personal loans performed well in Brazil (double-digit growth), Spain, Poland and Mexico.

SME loans decreased mainly due to declines in Spain, the UK and Portugal, partially offset by higher volumes in Brazil and Poland. Corporate loans rose, driven by Spain, Brazil, Mexico and Poland.

Customer deposits decreased 1% year-on-year. Excluding repurchase agreements and in constant euros, they rose 2%, with increases in time deposits (+9%, especially in individuals and SMEs) and mutual funds (+22%, mainly in individuals) due to the current interest rate environment. As a result, customer funds increased 4% in constant euros.

Results

Attributable profit in H1 2024 was EUR 3,326 million, 37% higher year-on-year. In constant euros, profit rose 35% year-on-year, as follows:

•Total income increased 12%, driven by net interest income, net fee income and gains on financial transactions which more than offset the higher negative impact of the hyperinflation adjustment in Argentina. SRF contributions ended in 2023, therefore there is no contribution in 2024.

Net interest income increased 12%, with increases in most countries, but especially in Spain and Portugal (due to good margin management), in Poland (higher activity and lower cost of deposits), in Brazil and Chile (higher volumes and deposit costs in a context of falling interest rates) and in Argentina (with double-digit growth). The exceptions were the UK (lower mortgage loans and higher deposit costs) and the US (lower volumes).

Our more targeted products and services offer boosted net fee income growth (+3%) mainly in Brazil (insurance fees and FX), Mexico (insurance and mutual funds), Poland (FX and funds) and in the US (real estate portfolio servicing fees with the FDIC).

•Costs remained flat year-on-year (-4% in real terms), reflecting transformation efforts through organizational simplification, process automation and global platform implementation. Of note were the performances in the US (-7%), Spain (-2%) and Argentina.

These transformation efforts, together with the strong revenue growth, contributed to a 4.8 pp efficiency ratio improvement year-on-year to 39.5%.

•Net loan-loss provisions fell slightly (-1%), due to a positive performance in Europe, mainly in Spain (credit quality improvement) and in the UK (macro improvement), which offset greater provisions in Brazil due to higher activity and the normalization in Mexico and Chile.

The cost of risk was 1.03% (compared to 0.92% in June 2023 and was stable versus 1.02% in December 2023). The NPL ratio stood at 3.15% (3.22% in June 2023).

RoTE in H1 2024 was 17.4% (18.1% annualizing the impact of temporary levy on revenue earned in Spain).

Compared to Q1 2024, attributable profit grew 22% in constant euros, with variations across the income statement impacted by the use of the new Argentine peso exchange rate and temporary levy on revenue earned in Spain in the first quarter. Excluding the temporary levy and Argentina, attributable profit would have increased 4% quarter-on-quarter due to good performance of net interest income and cost reduction.

→ Our priority is to continue expanding our leadership in consumer finance across our footprint, converging towards a more digital global operating model and implementing enhanced solutions (check-out lending, digital journeys in auto lending and operational leasing) through common platforms. → Loans increased 6% year-on-year in constant euros, +8% in auto in a market that is starting to recover. Deposits rose 14% in constant euros, in line with our strategy aimed at lowering funding costs and reducing net interest income volatility across the cycle, to be able to offer our customers better pricing. → Attributable profit reached EUR 1,070 million in H1 2024, a 4% increase year-on-year in both euros and constant euros, mainly driven by the solid net interest income and net fee income performances and cost control, despite the cost of risk normalization towards pre-pandemic levels.

Strategy

Digital Consumer Bank (Consumer) is a leading consumer finance company globally. It operates in 26 countries in Europe and the Americas and it serves the financing needs at the point of sale (both physical and digital) of 25 million customers. It combines our auto financing business, where we are the world leaders, our consumer lending business supported by Zinia and Openbank's advanced digital and retail banking capabilities.

The vision for Consumer is to become the preferred partner of our end customers and partners, offering greater profitability and value creation.

To respond to the changes the mobility and consumer finance ecosystem is undergoing and to support our aim of becoming Santander's platform to expand into new markets, we continue to transform our operating model:

•Offering global and best-in-class solutions, integrated into our partners' (OEMs, importers or retailers) processes, accompanying them as their increasingly digital business models evolve. We continue to work on improving local relationships with manufacturers to achieve global agreements.

•Simplifying and automating our processes to improve customer experience and increase scalability.

•Building and developing global platforms such as the leasing platform in auto, already operative in three European markets having expanded its functionalities in H1 2024, and Zinia’s technology in check-out lending, operative in Germany.

As part of our profitable growth strategy, we continue to capture deposits to increase NII stability and funding autonomy and boost growth while we also actively manage our balance sheet to make it more capital light. We launched our digital deposit gathering activities in January 2024 in the Netherlands and continue to work on expanding Openbank to other markets.

In the quarter, we made progress with our strategic priorities:

•In Europe, we are focusing on the transformation of the operating model with the aim of recovering pre-pandemic profitability levels, while providing the best services to our partners. To achieve this, we continue to pursue and develop commercial opportunities, such as strengthening our operational leasing solution or launching instalment loans with Apple through Zinia in Germany.

Moreover, we continue to simplify our operating model, having moved from one platform per country to three, towards our final goal of having one common platform.

•In the US, our focus is on recovering pre-pandemic profitability, driving efficiency savings and improving our service. In H1 2024, we continued to incorporate new strategic agreements in auto and prepare the launch of Openbank in H2 2024.

•In Latin America, our aim is to continue driving greater profitable growth where there are large commercial opportunities at good profitability levels. In Mexico, we plan to launch Openbank with a full value proposition to compete with other neobanks.

Business performance

After a difficult environment in previous years, H1 2024 showed signs of recovery resulting from inflation moderation, lower interest rate expectations and auto sales growth in our main markets.

In this environment, new lending increased 8% year-on-year, with solid growth across our main markets, especially in South America (led by Brazil). We continued to prioritize new business profitability over volumes growth in a high interest rate environment which is supporting the progressive RoRWA improvement.

The stock of loans and advances to customers rose 7%. In gross terms, excluding reverse repos and in constant euros, they were 6% up year-on-year, driven by Europe and Latin America.

We have a EUR 17 billion leasing portfolio which increased 2% year-on-year in constant euros, as growth in DCB Europe more than offset a decline in the US due to higher volumes of repurchases by dealers and despite increased electric vehicle activity.

Results

In H1 2024, attributable profit reached EUR 1,070 million, 4% higher than H1 2023. In constant euros, profit also increased 4%. By line:

•Total income improved 7%, mainly due to net interest income, which also rose 7%, supported by our active asset repricing actions and volumes growth in Europe, and higher volumes and lower interest rates in Brazil. However, performance in the US was weaker due to lower credit volumes which were offset by higher yields.

Net fee income also increased strongly, rising 27% in the period, driven by growth in Europe due to increased insurance penetration (particularly in Germany), in Brazil driven by volumes growth, and in the US in part due to auto fees.

Other revenue fell 18% due to lower gains on financial transactions in Europe (from high levels in 2023), the greater impact of the hyperinflation adjustment in Argentina and lower leasing income in the US due to lower volumes and passing on fiscal benefits (recorded in the tax line) from electric vehicle leasing to prices.

* Year-on-year growth in revenue in the US of +1% if we include the impact of the EV incentives in the tax line.

•Costs remained flat, reflecting our efficiency and transformation efforts. This is particularly evident in the US where costs declined 8% and in DCB Europe where they were flat despite our strategic investments in leasing and check-out lending platforms and business growth. As a result, the efficiency ratio improved 2.7 pp to 40.6%.

•Net loan-loss provisions increased 21%, affected by continued normalization in Europe and the US towards pre-pandemic levels (but still below our historical average) and higher volumes. Additionally, we increased the coverage of our CHF mortgage portfolio, there were lower portfolio sales than in 2023 and we recorded some regulatory charges. Credit quality remained controlled with the cost of risk at 2.17% and the NPL ratio at 4.81%.

RoTE in H1 2024 was 12.8% (13.0% annualizing the impact of the temporary levy on revenue earned in Spain).

Compared to Q1 2024, profit rose 31% in constant euros driven mainly by lower LLPs in the US (which more than offset higher provisions related to the CHF mortgage portfolio in Poland), and also by continued positive trends in total income, stable costs and the temporary levy recorded in Q1. There was some negative impact from the new peso exchange rate in Argentina in the quarter, particularly in NII which fell 2% (+1% excluding Argentina) mitigated by a positive impact in other income, with little impact on the bottom line.

→ We continue making our centres of expertise more sophisticated, deepening client relationships with focus on our Global Markets plan to build institutional wallet share, the US Banking Build-Out strategy, and actively managing capital. → Strong activity year-on-year, mainly supported by Global Banking (Global Debt Finance and Corporate Finance) and Global Markets as we execute our growth initiatives, and, to a lesser extent, in Global Transaction Banking. → Attributable profit reached EUR 1,405 million, a 5% drop year-on-year (in euros and in constant euros). A record first half revenue was offset by higher costs related to investments in the development of new capabilities, and higher provisions. Nevertheless, we maintained a leading position in efficiency and profitability.

Strategy

Innovation will continue to transform the global economy and shape competition as new technology develops. In this changing environment, the corporate and investment banking industry will continue to coexist with fintechs, digital assets and new digital players (e.g. virtual asset services providers), presenting collaboration opportunities within new sectors.

Substantial transition finance opportunities remain in ESG (e.g. Inflation Reduction Act, Net Zero initiatives) and certain sectors are expected to present significant financial needs, namely infrastructure, energy, life sciences, healthcare and technology.

At Santander, we are well prepared to capitalize on these opportunities, given our unique combination of global approach and local leadership, which we demonstrate through our position in various rankings.

We continue to make progress in the execution of our strategy to become a world-class CIB business, positioning ourselves as a trusted advisor to our clients while delivering profitable growth and maintaining dynamic capital management.

In H1 2024, we continued to make progress across our priorities:

•We are making our centres of expertise more sophisticated, with important reinforcements in sales, trading and banking across the businesses:

–In Global Banking (GB), we complemented our Global Industrials Group (GIGs) product offering through hires in Chemicals, US Specialty Finance, Paper & Packaging and Technology.

–In Global Markets (GM), we continue to execute our plan to increase activity with our corporate and institutional clients and further leverage technology. We have bolstered our institutional and leveraged loan sales teams. We also brought in traders for rates, FX and US inflation-linked derivatives.

As a result, we are starting to reap the rewards of our investments in 2023, with solid performance in institutional sales in Europe and the US.

As well as investing in markets infrastructure, we are focused on increasing revenue from cross-border flows and on supporting the US Banking Build-Out (US BBO) initiative, with enhanced trading and distribution capabilities, mainly in Leveraged Finance, Strategic Equity Solutions and Convertible Bonds.

•We are deepening our client relationships with a particular focus on the US, where we are taking our CIB franchise to the next level through the execution of the US BBO initiative, selectively expanding our client universe and product capabilities in areas adjacent to our strengths.

We have already made progress in targeting untapped wallets in M&A, Equity and Debt Capital Markets (ECM and DCM) and Leveraged Finance. Our new global Leveraged Finance franchise is helping us to create deeper relationships, especially in the US and EMEA, and leading to follow-on business opportunities

The collaboration plan for US BBO is already providing results and numerous ‘firsts’ as platforms come online and coverage teams are ramped up. Examples of this are: we closed the first corporate share buyback for a US company and we were appointed first global coordinator win for a US-listed IPO for the first time. In DCM, large US companies have relied on CIB for USD placements, and we are leading the reverse yankee bond market.

In Mexico, we are capitalizing on business opportunities leveraging our GM and US BBO initiatives, creating significant partnerships within the MEX-US corridor.

•We continued to actively manage capital through our Originate-to-Share model to drive forward industrial scale capital recycling. This has contributed to a limited increase in our capital consumption despite our business growth, enabling us to continue to deliver high profitability ratios.

Business performance

A high proportion of CIB's activity is customer related (84% of total income). Moreover, we have a high and growing percentage of capital-light activity and we actively manage our balance sheet, as reflected in our total revenue to risk-weighted assets ratio, which has improved 1.1 pp since 2022 to 7.0%.

Customer loans, which are concentrated in our Global Transaction Banking (GTB) and GB businesses, increased 11% year-on-year. In gross terms, excluding reverse repos and in constant euros, they increased 7%. Customer deposits rose 6% year-on-year. Excluding repos and in constant euros, they fell 6%, mainly driven by strategy changes to reduce excess corporate deposits.

By business line, we had the following performance:

•In Global Transaction Banking, strong increase in Export Finance, while Trade & Working Capital Solutions remained flat, partially offset by slightly lower activity year-on-year in Cash Management, affected by interest rate cuts, mainly in Latin America.

Trade & Working Capital Solutions continued to implement innovative trade solutions within the corporate segment, such as Trade Select, our integrated global supply chain finance platform.

We once again led the Export Finance market, especially in the sustainable technology sector, where we were awarded the Export Finance Deal of the Year for Baltic Power (offshore wind farm in Poland).

•Global Banking showed significant growth year-on-year in both Global Debt Financing (GDF), with DCM gaining market share in Europe, Latin America and the US, and Corporate Finance (CF) continuing to benefit from positive market momentum.

In GDF, Fund Financing performed well, as many funds re-leveraged their portfolios and big players continued to raise funds. CIB remains consistently among the top 3 European lead managers across all core securitized products. Structured Finance remained flat despite the lower activity in refinancing and greenfield projects compared to last year.

In CF, we closed several 'first' transactions in Leveraged Finance and ECM, while our M&A activity continues to span all sectors. Our role as one of MásMóvil's financial advisors was key in the completion of its joint venture with Orange.

•In Global Markets, we had good activity levels, mainly in Europe, where the institutional platform and the investments in human capital and technology are paying off. We had strong activity in rates, credit and securitized products. We saw significant growth in the US, where the US BBO is starting to show results across different businesses, with notable transactions closed, particularly in Equity Derivatives.

Results

Attributable profit in H1 2024 decreased 5% year-on-year to EUR 1,405 million. In constant euros, it also fell 5%, with the following detail:

•Total income rose 6% year-on-year, backed by double-digit growth in net interest income and net fee income, achieving record revenue in H1 2024. SRF contributions ended in 2023, therefore there is no contribution in 2024. Net interest income grew 22% boosted by GB, due to increased Leveraged Finance activity in CF and good performance in GDF. Net fee income grew 12%, particularly in GB on the back of the US BBO initiative. Gains on financial transactions fell due to lower results in Global Markets, especially in Brazil in a weak market.

By region, good revenue performance in North America and Europe, partially offset by a decrease in South America due to weaker activity mainly in Brazil.

Note: total income includes less material revenue from other activities (EUR 76 million in H1'23 and EUR 72 million in H1'24).

•Net loan-loss provisions amounted to EUR 96 million, up from very low levels in H1 2023 (EUR 7 million due to releases at the beginning of 2023).

RoTE was 19.0% in H1 2024 (19.1% annualizing the impact of the temporary levy on revenue earned in Spain), supported by our efforts in active capital management.

Compared to Q1 2024, attributable profit remained flat in constant euros, impacted by seasonality in revenue, interest rate cuts in some countries affecting net interest income and higher costs.

Strategy

Wealth Management & Insurance business was established in 2017 with the aim of enhancing its service model and value proposition as part of a common platform that leverages Santander's scale and capabilities.

Since then, it has been a relevant growth driver for the Group through its three businesses, delivering consistent double-digit growth and generating around one third of the Group's total fees, including those ceded to the commercial network.

•Santander Private Banking (PB) is our leading global platform serving private banking clients across 11 countries. We have a best-in-class service model and value proposition connecting clients and countries through a single platform.

•Santander Asset Management (SAM) is our global asset manager, which manufactures investment solutions for retail and institutional customers, with presence in more than ten countries and over 50 years of experience. SAM makes the most of its local client knowledge and global capabilities to provide customers the best investment opportunities.

•Santander Insurance provides protection solutions following a model based on strategic alliances with leading insurance companies, that enables us to have a comprehensive value proposition across 12 countries. We pair this with in-person and digital distribution capabilities to better serve our clients.

We continued with focus on the following strategic initiatives:

•In Private Banking, we already have a best-in-class global platform leading investment flows between Latin America, Europe and the US. Going forward, we are developing key growth opportunities to expand our footprint, such as in the Middle East where we have established a branch in the Dubai International Financial Center.

We also continue to complete our sophisticated value proposition to make the most of our connectivity between countries and segments, which exceeded EUR 3.3 billion in total alternatives commitments and more than EUR 52 billion in fee-based mandates.

Private Banking clients

Thousands

+13%

During Q2 2024, we were named the Best Global Private Bank for Cyber Security by the Professional Wealth Management Magazine, a Financial Times publication.

•In SAM, we operate as a global asset manager leveraging our scale, global investment capabilities and product distribution hubs. In terms of retail distribution, we are implementing an advisory model, having established common investment views across all countries, supported by a global platform offering enhanced customer experience.

In terms of our Alternatives business, we are working on completing our value proposition while improving our scale. We already have EUR 3.1 billion of total global commitments across four different investment strategies: Private Debt, Infrastructure & Energy, Real Estate and Fund of Funds.

The main awards received by SAM during Q2 2024 include the Best Solidarity Fund in Spain by Expansion-Allfunds as well as being the asset manager with most awards at the Salmon awards in Chile with five prize-winning funds.

•In Insurance, we are delivering more value to our customers and simplifying our operations. In addition to our traditional focus on life and home businesses, we are shifting our mix towards higher growth verticals such as savings, health and SMEs, having launched the new health value offer (OneCare in Portugal and the UC Christus in Chile), and a new Unit Linked offer in Chile and Mexico.

Additionally, we are focused on improving customer growth and loyalty by developing fully digital servicing and claims capabilities while work is underway to maximize the value of our customer portfolio. Finally, we are also developing global platforms such as the new Latin American Autocompara, an integration of our motor insurance comparison engines in our Latin American markets, to capture additional business and unlock synergies.

The EBITDA margin in PagoNxt improved 8.9 pp to 20.1%.

PagoNxt and Cards strategy

PagoNxt continued to make progress in its key strategic priorities:

•In Getnet, we continued to consolidate our platform. We deployed new global solutions which are enabling us to gain market share across most of our footprint.

In addition, as part of our transformation in merchant in Europe, we remain focused on our current value proposition in Spain and Portugal, working with local partners in other European markets and doubling down in our strategic markets in Latin America. In line with this strategy, in June we decided to discontinue our merchant platform in Germany.

•In Ebury, we continued our expansion by developing specialist vertical-specific solutions, such as mass payments, accelerating the geographical expansion in emerging markets such as South Africa, expanding its product suite, especially FX risk management solutions, and continuously evolving online capabilities to better serve our customers.

•In PagoNxt Payments, we made progress in the development of Payments Hub, our modern global A2A payments processing platform, aiming to achieve an industry-leading cost per transaction combined with value-added services. Our goal is to deploy all these services to benefit both the Group and other open market participants.

Also, as part of our strategy to promote the use of common platforms across the Group to maximize operational leverage and provide the best service, we decided to discontinue our Superdigital platform in Latin America. Through our global platform we will continue to promote banking services in the mass segment and develop financial inclusion proposals.

In Cards, we continued to make progress in our priorities:

•Expand the business: we made progress implementing Card Risk Data Lab in Spain, Chile, Mexico and Uruguay, reaching more than 500,000 new pre-approved customers in H1 2024.

We are also increasing the connection between card issuing and acquiring platforms to offer value-added products and services. We launched a differential joint value proposition (card + PoS) in Spain, and will follow soon in Chile.

•Improve customer satisfaction: we are working to offer the best card payment experience in a simple way at any time, through what we call Invisible Payments. We made progress in the implementation of Click to Pay, an industry solution for e-commerce payments. We continued to roll out digital services on a global scale, such as the token manager, which already manages than 150 million of tokens at Santander banks.

•Implement Plard, our global card platform, which already manages more than 75,000 new debit cards in Brazil, where we expect the migration of the debit portfolio before year-end. In

Chile, we will start to manage new customer debit cards in Q3. In Mexico, the new authorizer engine is now live serving 2.9 million cards.

Business performance

Loans and advances to customers decreased 3% year-on-year. Excluding reverse repurchase agreements and in constant euros, gross loans rose 4%, driven mainly by Cards in Brazil and Mexico.

Payments has very small amount of deposits, concentrated in PagoNxt. These deposits (excluding repos) amounted to EUR 994 million and rose 66% year-on-year in euros and in constant euros.

Results

Attributable profit was EUR 49 million in H1 2024, 78% down year-on-year affected by write-downs related to the discontinuation of our merchant platform in Germany and Superdigital in Latin America. Excluding these impacts, profit was EUR 292 million, up 31% year-on-year. In constant euros, profit rose 30%, by line:

•Total income grew 3%. Excluding a one-time positive fee recorded in Q1 2023 from commercial agreements in Brazil, total income increased 6%, driven by activity improvement.

•Costs up 4%, but flat in real terms, despite our investments in platforms both in Cards and PagoNxt.

•Net loan-loss provisions, which are mainly related to the Cards business, decreased 3%, driven by the good performances in South America and Europe.

Compared to Q1 2024, worse bottom line affected by the already mentioned write-downs. Excluding them, profit rose 16% in constant euros driven by good revenue and cost performance.

•Costs rose 2% year-on-year, growing below inflation, despite our investment in platforms.

•Net loan-loss provisions fell 3%, due to good risk management and to a lower interest rate environment in South America.

In H1 2024, RoTE in Cards was 35.0%.

Compared to Q1 2024, variations were significantly impacted by the use of the new Argentine peso exchange rate. Excluding Argentina, profit rose 6% in constant euros, supported by good performance in revenue and costs (mainly in the UK).

→ The Corporate Centre continued to support the Group. → The Corporate Centre’s objective is to define, develop and coordinate the Group's strategy and aid the operating units by contributing value and carrying out the corporate oversight and control function. It also carries out functions related to financial and capital management. → Attributable loss of EUR 609 million, improving 2% compared to H1 2023 mainly due to lower costs, more than offsetting the worse performance of gains on financial transactions (higher negative impact from foreign currency hedging), with net interest income virtually flat year-on-year.

Strategy and functions

The Corporate Centre contributes value to the Group, through the following functions, among others:

•Global control frameworks and supervision.

•Fostering the exchange of best practices in cost management, which enables us to be one of the most efficient banks.

•Collaborating in the definition and execution of the global strategy, competitive development operations and projects that ensure we meet the business plan.

•Contributing to the launch of projects that will be developed by our global businesses aimed at leveraging our worldwide presence to generate economies of scale.

•Ensuring open and constructive communication with shareholders, analysts, investors, bondholders, rating agencies and other market players.

•Adding value to our businesses, countries and divisions by encouraging the exchange of best practices, driving and managing innovative global initiatives and defining corporate policies to improve efficiency in our processes and service quality for our customers.

It also coordinates the relationship with European regulators and supervisors and carries out functions related to financial and capital management, as follows:

•Financial Management functions:

–Structural management of liquidity risk associated with funding the Group’s recurring activity and stakes of a financial nature. At the end of June 2024, the liquidity buffer was EUR 304 billion.

This is done ensuring the diversification of funding sources (issuances and other), maintaining an adequate profile in volumes, maturities and costs.

The price of these transactions with other Group units is the market rate that includes all liquidity concepts (which the Group supports by immobilizing funds during the term of the transaction) and regulatory requirements (TLAC/MREL).

–We also actively manage interest rate risk is also in order to dampen the impact of interest rate changes on net interest income, conducted via high credit quality, very liquid and low capital consumption derivatives.

–Strategic management of exposure to exchange rates in equity and dynamic management of the FX hedges related to the units’ next twelve months results in euros. The net investments in equity currently hedged totalled EUR 17,247 million (mainly in Mexico, Brazil and the UK) with different FX instruments (spots and forwards).

•Management of total capital and reserves: capital analysis, adequacy and management of the Group including: coordination with subsidiaries, monitoring profitability to maximize shareholder returns, setting solvency targets and capital contributions, and monitoring the capital ratio in both regulatory and economic terms, and efficient capital allocation to the units.

Results

In H1 2024, the attributable loss was EUR 609 million, 2% better than in H1 2023 (a EUR 620 million loss), by line:

•Net interest income remained steady (worsening EUR 6 million), as the higher liquidity buffer remuneration nearly offset higher interest expense related to TLAC/MREL issuances.

•Weaker gains on financial transactions (EUR 95 million more negative than H1 2023), due to greater negative impacts from foreign currency hedging.

•On the other hand, costs improved 8% compared to H1 2023, driven by ongoing simplification measures.

•Lastly, other results and provisions increased slightly year-on-year.

→ We continue to accelerate our business transformation to achieve higher growth and a more efficient operating model. → New business lending volumes improved year-on-year, however the stock of loans declined, still affected by prepayments and in a context of higher interest rates. Customer deposits rose, mainly due to time deposits. → Attributable profit increased 26% (+24% in constant euros) to EUR 3,187 million, with strong revenue growth, mainly from net interest income in Spain, Portugal and Poland.

Strategy

In Q2 2024, we remained focused on growing our business and transforming our operating model, to improve efficiency and customer experience.

•In Retail, we continued to drive digitalization through a common online banking and mobile experience, while reducing running costs and streamlining products and processes.

•In CIB, we were focused on deepening customer relationships and boosting our distribution capabilities.

•We continued to grow our Wealth business, which is a key driver of fee generation, while increasing its efficiency by developing centralized global technology platforms.

•In Payments, we expanded our businesses across Europe through PagoNxt and Cards.

Additionally, our capital discipline allowed us to maximize the value of the businesses, through sustainable asset rotation and high-value origination.

Business performance

There were positive dynamics in the quarter, with new business volumes improving year-on-year, supported by 525,000 more customers year-on-year.

Loans and advances to customers rose 2% year-on-year. In gross terms, excluding reverse repurchase agreements and in constant euros, they decreased 1%, with falls across most countries, except Poland due to record mortgage and personal loan origination and CIB portfolio growth. By business, they decreased in Retail (due to mortgage prepayments in the UK and Spain and lower loans in SMEs) and Payments.

Customer deposits increased 1% year-on-year. Excluding repurchase agreements and in constant euros they also rose 1%, as the increase in time deposits (+16%) offset the decrease in

demand deposits (-3%). By business, deposits rose mainly due to time deposits in Retail, CIB and Wealth. Mutual funds increased 16% in constant euros, with growth in all countries.

Results

Attributable profit in H1 2024 was EUR 3,187 million, up 26% year-on-year. In constant euros, it grew 24%, as follows:

•Total income increased 10%, due to higher net interest income (+7%), with strong growth in Spain, Portugal and Poland (good margin management), which more than offset the fall in the UK (lower mortgage volumes and higher deposit costs). Net fee income rose 4%, mainly driven by mutual fund fees in Spain (Objetivo campaign). SRF contributions ended in 2023, therefore there was no contribution in 2024.

•Costs increased 4%, in line with inflation, especially in the UK where salaries were impacted by inflation and in Poland due to the tight labour market. Net operating income rose 15% and the efficiency ratio improved by 2.6 pp, reaching 39.3%.

•Net loan-loss provisions decreased 23%, driven by credit quality improvement across countries and also due to macro improvement in the UK. We had additional provisions related to the CHF mortgage portfolio in Poland, increasing its coverage. The cost of risk stood at 0.39% (0.42% June 2023).

•Other results and provisions increased 22%, impacted by the higher temporary levy on revenue earned in Spain.

Compared to Q1 2024, profit rose 7% in constant euros, due to having recorded the temporary levy on revenue earned in Spain in Q1 2024 and a positive performance in costs. The quarter was impacted by the higher CHF mortgage portfolio provisions in Poland.

→ Our strategy is focused on strengthening our leadership in auto and non-auto through strategic alliances and better service through new operational and non-auto leasing platforms, with Zinia in check-out lending. → In H1 2024, new business volumes rose 2% year-on-year in constant euros (+4% in auto), in an environment that is still tending to limit consumption (despite this, the auto market performed well). Deposits increased 24% in constant euros, in line with our objective to increase retail funding through common platforms to reduce liability costs. → Attributable profit of EUR 453 million, down 13% year-on-year in constant euros as the good performance in net interest income and net fee income with flat costs, were more than offset by cost of risk normalization towards pre-pandemic levels and higher CHF mortgage provisions.

Strategy

The vision in our DCB Europe business is to become the preferred partner of our final customers and partners, offering greater profitability and value creation.

We are thus transforming our operating model:

•We continue to offer global solutions integrated into the processes of our partners - manufacturers, importers and retailers - accompanying them as their increasingly digital business models evolve.

•Simplifying and automating our processes to improve customer experience and gain in scalability.

•Building and developing global platforms. In Q2 2024, we continued strengthening our operational leasing solution in Italy, Spain, France and Germany. Zinia, our check-out lending platform, launched a service of instalment loans with Apple (physical point of sale and e-commerce) in Germany. Openbank is present in four markets (Spain, the Netherlands, Portugal and Germany).

Business performance

The stock of loans and advances to customers rose 8%. In gross terms, excluding reverse repos and in constant euros, it also rose 8% year-on-year, reaching EUR 138 billion. New business volumes rose 2% year-on-year in constant euros (+4% in auto).

In line with our strategy to increase retail funding to reduce funding costs, customer deposits increased 24% year-on-year. Excluding repos and in constant euros, they also grew 24% to EUR 77 billion. Mutual funds increased double-digits from very low levels. Our access to wholesale funding markets remained strong and diversified.

Results

In H1 2024, attributable profit reached EUR 453 million, a 13% decline year-on-year. In constant euros, profit also decreased 13%, as follows:

•Total income improved 7%, mainly due to net interest income (+7%), supported by active loan repricing and customer deposit growth. In addition, net fee income grew 14%, driven by greater penetration in direct insurance, especially in Germany. SRF contributions ended in 2023, therefore there is no contribution in 2024.

•Costs remained flat, absorbing the effects of inflation and business growth. Net operating income grew 14% and the efficiency ratio improved 3.2 pp to 46.2%.

•Net loan-loss provisions increased 40%, significantly impacted by additional provisions in Q2 2024 to increase the coverage of the CHF mortgage portfolio. Additionally, they rose due to expected normalization (still below our historical average), volumes growth, some regulatory impacts and lower portfolio sales than in 2023. Despite all of this, cost of risk remained at very low levels (0.72%), normalizing in line with expectations and the NPL ratio stood at 2.31%.

The largest contribution to profit came from Germany (EUR 123 million), followed by the Nordic countries (EUR 122 million), France (EUR 63 million) and the UK (EUR 57 million).

Compared to Q1 2024, profit fell 2% in constant euros as the good performance in total income and especially in costs, were more than offset by the higher CHF mortgage provisions.

Customer deposits declined 4% in deposits in constant euros, mainly due to funding strategy changes in CIB in the US, partially mitigated by higher deposits in Mexico and Consumer in the US. → Attributable profit in H1 2024 was EUR 1,347 million, flat year-on-year (-3% in constant euros), with top line growth in both countries offset by higher costs (inflation and investments) and cost of risk normalization.

Strategy

We continued to pursue business transformation across the US and Mexico, while leveraging our global and regional scale. We:

•Remained focused on executing the transformation of our Retail and Consumer businesses in both countries. The simplification of our product portfolio and streamlining of our operations continued.

•Advanced in the adoption of global technology platforms to deliver an enhanced digital experience. For example, in April we announced the launch of our national deposit platform under the Openbank brand later this year in the US.

•Continued to invest in our Corporate & Investment Banking Build-Out in the US, with the expansion of our advisory services and enhanced product offering capabilities, resulting in strong revenue growth.

•Pursued growth in Wealth, with targeted investments to enhance our capabilities and strengthen growth levers.

•Strengthened our regional operating model in technology and operations to consolidate know-how, digitalization, digital hubs, front and back-office automation driving more effective and efficient operations.

Business performance

Loans and advances to customers rose 5% year-on-year. In gross terms, excluding reverse repos and in constant euros, they were 3% up primarily driven by robust growth in mortgages, auto, cards and corporates in Mexico and CIB and auto in the US.

Customer deposits rose 2% year-on-year. Excluding repos and in constant euros, they declined 4%. This was mainly driven by strategy changes to reduce excess corporate deposits in CIB in the US, partially offset by deposit growth in Retail in Mexico and in Consumer in the US.

Results

Attributable profit in H1 2024 was EUR 1,347 million, flat year-on-year. In constant euros, profit decreased 3%, as follows:

•Total income grew 7% year-on-year, driven by a strong revenue performance in CIB in the US, where we are moving forward with our capabilities build-out, and by a good performance across the board in Mexico (volumes growth and wider customer margins).

•Costs increased 7%, driven by inflation and higher digital and investments embedded in our transformation programme in Retail in Mexico and in CIB in the US. These were partially compensated by significant efficiencies in our Consumer and Commercial businesses in the US resulting from our transformation initiatives.

•Net loan-loss provisions rose 21%, reflecting the strong business growth in Retail and Cards in Mexico, as well as the expected cost of risk normalization in Mexico and auto in the US.

Compared to Q1 2024, attributable profit grew 9% in constant euros, fuelled by revenue growth in Retail in Mexico and Consumer in the US and lower net loan-loss provisions, particularly in Consumer in the US and Payments in Mexico.

Strategy

In Q2 2024, the main initiatives by business were:

•In Retail, we continued to focus on becoming a digital bank with branches, optimizing our product and service offering in digital channels and improving customer experience.

•In Consumer, we continued developing new business models and strengthening OEM agreements.

•In CIB, we are evolving towards a pan-regional offering, focusing on Markets and Corporate Finance.

Business performance

The variations in constant euros, both in the balance sheet and results, have been calculated considering the Argentine peso exchange rate on the last working day of each of the periods presented. Additionally, from Q2 2024 onwards, a theoretical exchange rate has been used for the Argentine peso. For further information, see the 'Alternative performance measures' section in the appendix to this report.

Loans and advances to customers fell 4% year-on-year. In gross terms, excluding reverse repos and in constant euros, they rose 7%, with increases in all global businesses.

Results

In H1 2024, attributable profit reached EUR 1,681 million, 15% higher than in H1 2023. In constant euros, profit rose 19%, as follows:

•Total income increased 10%, supported by 23% net interest income growth, up in all global businesses and rising double-digits in Brazil and Chile (higher volumes and benefiting from negative sensitivity of their balance sheet in a context of falling interest rates) and in Argentina. In net fee income, the good performance in Brazil (insurance and foreign exchange fees) Uruguay (Consumer) and Peru (CIB) offset lower fees in Argentina and Chile (from high levels in 2023). Gains on financial transactions were impacted by lower results in CIB in Brazil and Argentina.

•Costs remained flat and fell 4% in real terms, driven by lower costs in Argentina and our good cost management in Brazil and Chile. Efficiency improved by 3.7 pp to 35.4%.

•Net loan-loss provisions were up 10% due to Brazil, where provisions increased below portfolio growth, and normalization in Chile. The cost of risk stood at 3.50% (3.32% in June 2023).

Compared to Q1 2024, variations were significantly impacted by the use of the new Argentine peso exchange rate. Excluding Argentina, profit rose 7% in constant euros, supported by higher net interest income and net fee income in Brazil and Chile and controlled costs.

STRATEGY AND TARGET

Our sustainability strategy focuses on supporting business growth, meeting our stakeholders' expectations and making Santander more resilient through sound risk management, data protection and privacy, transparency, culture and governance. This strategy focuses on areas with the greatest risks or opportunities for the Group or where we can have the greatest impact.

We continued to make progress towards meeting the goals set at Investor Day, which include supporting the transition to a green economy and promoting inclusive growth.

Green finance	Socially Responsible Investments (SRI) AuMs	Financial inclusion
EUR 123.4 billion	EUR 74.0 billion	2.8 million people
Target 1: EUR 120 bn 2025	Target: EUR 100 bn 2025	Target: 5 mn 2025
Target 2: EUR 220 bn 2030
Note: targets were set before the publication of the European taxonomy in Q2 2023. Therefore, target definitions are not fully aligned with the taxonomy. For further information, see the 'Alternative performance measures' section in the appendix to this report.

GROUP

•We achieved the target we set in 2019 to invest or mobilize EUR 120 billion in green finance before 2025 18 months early. This put us in a good position to achieve our objective to reach EUR 220 billion in green finance between 2019 and 2030.

•In Q2 2024, Euromoney gave us the following awards:

–Best Bank for Corporate Responsibility in Western Europe, and also in Mexico, Portugal and Uruguay.

•We signed an asset securitization together with EIB Group. This will allow us to mobilize EUR 1.2 billion, that will contribute to financing green and women's entrepreneurship projects of SMEs and mid-caps in Spain.

•In Q2 2024, we published sustainability reports in Brazil, Mexico and the US, where we explain our local sustainability actions. In May, we published the 2023 University Report with information on all the activities throughout the year done by Santander Universidades and Universia to boost education, employability and entrepreneurship.

Share capital reduction of 2.09% under the shareholder remuneration charged against 2023 results

On 25 June, the board of directors reduced the Bank's share capital by EUR 165,652,500, cancelling 331,305,000 of its own shares. These shares accounted for 2.09% of share capital prior to the reduction and were acquired as part of the buyback programme that ran between February and June 2024 under the shareholder remuneration charged against 2023 results. The capital reduction, which was approved at the general shareholders’ meeting on 22 March 2024, was registered with the Commercial Registry of Cantabria on 1 July. Consequently, Article 5 of the Bylaws was amended to reflect that the Bank’s share capital is set at EUR 7,747,136,786, comprising 15,494,273,572 shares with a nominal value of EUR 0.50 per share, all of the same class and affording the same rights.

The six share buyback programmes charged against 2021, 2022 and 2023 results and the related share capital reductions have resulted in the cancellation of almost 11% of the Bank's shares (1,846,367,730 shares) since November 2021.

Changes to the board of directors

On 27 June, having obtained the corresponding regulatory approvals, Carlos Barrabés (filling the vacancy left by Bruce Carnegie-Brown), and Antonio Weiss (to succeed Ramiro Mato, who also ceased to be a member of the board of directors), joined the board as independent directors.

Changes to the board committees

On 27 June, Carlos Barrabés joined the nomination committee, the responsible banking, sustainability and culture committee and the innovation and technology committee to replace Ramiro Mato, who also ceased to be a member of other committees (executive, audit and risk supervision, regulation and compliance).

Also, on 23 July, Sol Daurella was appointed Chair of the responsible banking, sustainability and culture committee.

The updated composition of the board committees is available on our corporate website (www.santander.com).

Changes to the organizational structure of the Group's Senior Management

On 29 April, the board of directors approved the following appointments, subject to regulatory approval:

•Javier García Carranza as the new Global Head of Wealth Management & Insurance to succeed Víctor Matarranz, who will support Héctor Grisi in executing our strategy.

Dividends and shareholder remuneration

In application of the shareholder remuneration policy for 2023, the bank paid an additional cash dividend of EUR 9.50 cents per share against 2023 results in May 2024.

Likewise, and in application of the shareholder remuneration policy for 2023, a second share buyback programme was carried out between February and June 2024 for EUR 1,459 million, in which a total of 331,305,000 shares were acquired, representing 2.09% of the share capital. Under the authorization of the 22 March 2024 AGM, on 25 June 2024, the board agreed to amortize the shares acquired and to the corresponding reduction of share capital under the terms described in the 'Corporate governance' section.

As a result, the total shareholder remuneration against 2023 results, including the cash dividend of EUR 8.10 cent per share paid in November 2023 and the first share buyback programme (EUR 1,310 million) completed in January 2024, was EUR 5,552 million, equivalent to approximately 50% of the Group’s reported profit (excluding non-cash, non-capital ratios impact items) in 2023. This remuneration was split approximately equally with around 50% in cash dividends and 50% through share buybacks.

Share price performance

Santander's shares are listed on five markets: on four exchanges in Spain (Madrid, Barcelona, Bilbao and Valencia), in the US (as an ADR), in the UK (as a CDI), in Poland and in Mexico (Sistema Internacional de Cotizaciones).

During Q2 2024, disinflation slowed down. Fluctuations in interest rate expectations reflected market uncertainties about central bank decisions. While the ECB made its first interest rate cut in June, the Federal Reserve and the Bank of England decided to hold interest rates.

There has also been some volatility due to the recent electoral processes, which has impacted the markets in Mexico and Europe, although growth expectations in the eurozone remain reasonably positive. In the UK, the economic outlook is not expected to be greatly impacted by the results of the elections.

In this environment, equity markets performed well. Santander's share price ended June 2024 with positive return of 14.6% in the year to date. In the banking sector, the Eurostoxx Banks, the eurozone's main index, was 15.6% up, while the DJ Stoxx Banks rose by 15.2% and the MSCI World Banks increased 11.3%. The other main indices also closed up (the Ibex 35 +8.3% and the DJ Stoxx 50 +9.7% since end 2023).

				APMs

Alternative performance measures (APMs)

In addition to the financial information prepared under IFRS, this consolidated directors’ report contains financial measures that constitute alternative performance measures (APMs) to comply with the guidelines on alternative performance measures issued by the European Securities and Markets Authority on 5 October 2015 and non-IFRS measures.

The financial measures contained in this consolidated directors’ report that qualify as APMs and non-IFRS measures have been calculated using the financial information from Santander but are not defined or detailed in the applicable financial information framework or under IFRS and therefore have neither been audited nor are susceptible to being fully audited.

We use these APMs and non-IFRS measures when planning, monitoring and evaluating our performance. We consider these APMs and non-IFRS financial measures to be useful metrics for management and investors to facilitate operating performance comparisons from period to period. While we believe that these APMs and non-IFRS financial measures are useful in evaluating our business, this information should be considered as supplemental in nature and is not meant as a substitute of IFRS measures. In addition, the way in which Santander defines and

calculates these APMs and non-IFRS measures may differ from the calculations by other companies with similar measures and, therefore, may not be comparable.

The APMs and non-IFRS measures we use in this document can be categorized as follows:

Underlying results

In addition to IFRS results measures, we present some results measures which are non-IFRS and which we refer to as underlying measures. These measures allow in our view a better year-on-year comparability given that they exclude items outside the ordinary performance of our business (e.g. capital gains, write-downs, impairment of goodwill) or certain line items have been reclassified in the underlying ("adjusted") income statement, as their impact on profit is zero, to facilitate comparisons with prior quarters and better understand the trends in the business.

In addition, in the section "Financial information by segment", relative to the primary and secondary segments, results are only presented on an underlying basis in accordance with IFRS 8, and reconciled on an aggregate basis to our IFRS consolidated results to the consolidated financial statements, which are set out below.

Profitability and efficiency ratios

The purpose of the profitability and efficiency ratios is to measure the ratio of profit to capital, to tangible capital, to assets and to risk- weighted assets, while the efficiency ratio measures how much general administrative expenses (personnel and other) and amortization costs are needed to generate revenue.

Additionally, goodwill adjustments have been removed from the RoTE numerator as, since they are not considered in the denominator, we believe this calculation is more correct.

Ratio	Formula	Relevance of the metric
RoE	Profit attributable to the parent (annualized)	This ratio measures the return that shareholders obtain on the funds invested in the bank and as such measures the company's ability to pay shareholders.
(Return on equity)	Average stockholders’ equity 1 (excl. minority interests)
RoTE	Profit attributable to the parent (annualized)2	This indicator is used to evaluate the profitability of the company as a percentage of its tangible equity. It's measured as the return that shareholders receive as a percentage of the funds invested in the entity less intangible assets.
(Return on tangible equity)	Average stockholders' equity 1 (excl. minority interests) - intangible assets
RoA	Consolidated profit (annualized)	This metric measures the profitability of a company as a percentage of its total assets. It is an indicator that reflects the efficiency of the company's total funds in generating profit.
(Return on assets)	Average total assets
RoRWA	Consolidated profit (annualized)	The return adjusted for risk is a derivative of the RoA metric. The difference is that RoRWA measures profit in relation to the bank's risk-weighted assets.
(Return on risk-weighted assets)	Average risk-weighted assets
Efficiency ratio	Operating expenses 3	One of the most commonly used indicators when comparing productivity of different financial entities. It measures the amount of funds used to generate the bank's total income.
	Total income

1. Stockholders’ equity = Capital and Reserves + Accumulated other comprehensive income + Profit attributable to the parent + Dividends.

2. Excluding the adjustment to the valuation of goodwill.

3. Operating expenses = Administrative expenses + amortizations.

Credit risk indicators

The credit risk indicators measure the quality of the credit portfolio and the percentage of non-performing loans covered by provisions.

Ratio	Formula	Relevance of the metric
NPL ratio (Non-performing loans)	Credit impaired loans and advances to customers, customer guarantees and customer commitments granted	The NPL ratio is an important variable regarding financial institutions' activity since it gives an indication of the level of risk the entities are exposed to. It calculates risks that are, in accounting terms, declared to be credit impaired as a percentage of the total outstanding amount of customer credit and contingent liabilities.
	Total Risk 1
Total coverage ratio	Total allowances to cover impairment losses on loans and advances to customers, customer guarantees and customer commitments granted	The total coverage ratio is a fundamental metric in the financial sector. It reflects the level of provisions as a percentage of the credit impaired assets. Therefore it is a good indicator of the entity's solvency against customer defaults both present and future.
	Credit impaired loans and advances to customers, customer guarantees and customer commitments granted
Cost of risk	Allowances for loan-loss provisions over the last 12 months	This ratio quantifies loan-loss provisions arising from credit risk over a defined period of time for a given loan portfolio. As such, it acts as an indicator of credit quality.
	Average loans and advances to customers over the last 12 months

Other indicators

The Group has a series of additional financial metrics which facilitate analysis of the underlying business trends and performance. It also has another set of ESG indicators which enable us to track the progress of our Responsible Banking objectives.

Ratio	Formula	Relevance of the metric
TNAV per share	Tangible book value 1	This is a very commonly used ratio used to measure the company's accounting value per share having deducted the intangible assets. It is useful in evaluating the amount each shareholder would receive if the company were to enter into liquidation and had to sell all the company's tangible assets.
(Tangible equity net asset value per share)	Number of shares excluding treasury stock
Price / tangible book value per share (X)	Share price	This is one of the most commonly used ratios by market participants for the valuation of listed companies both in absolute terms and relative to other entities. This ratio measures the relationship between the price paid for a company and its accounting equity value.
	TNAV per share
LTD ratio	Net loans and advances to customers	This is an indicator of the bank's liquidity. It measures the total (net) loans and advances to customers as a percentage of customer deposits.
(Loan-to-deposit)	Customer deposits
Loans and advances (excl. reverse repos)	Gross loans and advances to customers excluding reverse repos	In order to aid analysis of the commercial banking activity, reverse repos are excluded as they are highly volatile treasury products.
Deposits (excl. repos)	Customer deposits excluding repos	In order to aid analysis of the commercial banking activity, repos are excluded as they are highly volatile treasury products.
PAT + After tax fees paid to SAN (in Wealth Management & Insurance)	Net profit + fees paid from Santander Asset Management and Santander Insurance to Santander, net of taxes, excluding Private Banking customers	Metric to assess Wealth Management & Insurance's total contribution to Grupo Santander profit.

Local currency measures

We make use of certain financial measures in local currency to help in the assessment of our ongoing operating performance. These non-IFRS financial measures include the results of operations of our subsidiary banks located outside the eurozone, excluding the impact of foreign exchange. Because changes in foreign currency exchange rates do not have an operating impact on the results, we believe that evaluating their performance on a local currency basis provides an additional and meaningful assessment of performance to both management and the company’s investors.

The Group presents, at both the Group level as well as the business unit level, the real changes in the income statement as well as the changes excluding the exchange rate effect ("excluding FX" or "constant euros"), as it considers the latter facilitates analysis, since it enables businesses movements to be identified without taking into account the impact of converting each local currency into euros.

Said variations, excluding the impact of exchange rate movements, are calculated by converting income statement lines for the different business units comprising the Group into our presentation currency, the euro, applying the average exchange rate for H1 2024 to all periods contemplated in the analysis. We use this method for all countries with the exception of Argentina, where we use the exchange rate on the last working day of each period presented, given it is a hyperinflationary economy, to mitigate the distortions caused by the hyperinflation.

The Group presents, at both the Group level as well as the business unit level, the changes in euros in the balance sheet as well as the changes excluding the exchange rate effect for loans and advances to customers excluding reverse repurchase

agreements (repos) and customer funds (which comprise deposits and mutual funds) excluding repos. As with the income statement, the reason is to facilitate analysis by isolating the changes in the balance sheet that are not caused by converting each local currency into euros.

These changes excluding the impact of exchange rate movements are calculated by converting loans and advances to customers excluding reverse repos and customer funds excluding repos, into our presentation currency, the euro, applying the closing exchange rate on the last working day of June 2024 to all periods contemplated in the analysis. We use this method to calculate the variations in loans and advances to customers excluding reverse repos and customer funds excluding repos for all countries with the exception of Argentina, where we use the exchange rate on the last working day of each period presented, given it is a hyperinflationary economy, to mitigate the distortions caused by the hyperinflation.

The average and period-end exchange rates for the main currencies in which the Group operates are set out in the table below.

From Q2 2024, we have begun to apply a new theoretical exchange rate for the Argentine peso. This decision is due to the significant divergence that we have observed between the official exchange rate and other macroeconomic magnitudes, mainly inflation. The new theoretical exchange rate also reflects the implicit exchange rate observed in certain transactions ordered between market participants under the prevailing economic conditions, such as the repatriation of dividends from businesses in Argentina. This theoretical rate has been modelled by our Economic Research Team primarily taking into account the inflation differential of Argentina with respect to the US.

Exchange rates: 1 euro / currency parity

1. From Q2 2024 onwards, a theoretical exchange rate has been used, as explained in the text above. We continue to apply the official ARS exchange rate to all prior periods.

Impact of inflation rate on the variations of operating expenses

Santander presents, for both the Group and the business units included in the primary and secondary segments: i) the changes in operating expenses in euros, ii) the changes excluding the exchange rate effect with the exception of Argentina which is calculated as described above in "Local currency measures", and iii) the changes excluding the exchange rate effect minus the effect of average inflation over the last twelve months except for Argentina as cost growth in euros should already largely reflect the effect of hyperinflation on exchange rates. The reason is that the two latter facilitate analysis for management purposes.

Inflation is calculated as the arithmetic average of the last twelve months for each country and, for the regions, as the weighted average of each country comprising the region's inflation rate, weighted by each country's operating expenses in the region. For South America, we exclude the impact of inflation in Argentina from the calculation of the region's average inflation as cost growth in euros should already largely reflect the effect of hyperinflation on exchange rates.

The table below shows the average inflation rates calculated as indicated.

Important information

Non-IFRS and alternative performance measures

This report contains financial information prepared according to International Financial Reporting Standards (IFRS) and taken from our consolidated financial statements, as well as alternative performance measures (APMs) as defined in the Guidelines on Alternative Performance Measures issued by the European Securities and Markets Authority (ESMA) on 5 October 2015, and other non-IFRS measures. The APMs and non-IFRS measures were calculated with information from Grupo Santander; however, they are neither defined or detailed in the applicable financial reporting framework nor audited or reviewed by our auditors. We use these APMs and non-IFRS measures when planning, monitoring and evaluating our performance. We consider them to be useful metrics for our management and investors to compare operating performance between periods. APMs we use are presented unless otherwise specified on a constant FX basis, which is computed by adjusting comparative period reported data for the effects of foreign currency translation differences, which distort period-on-period comparisons. Nonetheless, the APMs and non-IFRS measures are supplemental information; their purpose is not to substitute IFRS measures. Furthermore, companies in our industry and others may calculate or use APMs and non-IFRS measures differently, thus making them less useful for comparison purposes. APMs using ESG labels have not been calculated in accordance with the Taxonomy Regulation or with the indicators for principal adverse impact in SFDR. For further details on APMs and Non-IFRS Measures, including their definition or a reconciliation between any applicable management indicators and the financial data presented in the consolidated financial statements prepared under IFRS, please see the 2023 Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission (the SEC) on 21 February 2024 (https://www.santander.com/content/dam/santander-com/en/documentos/informacion-sobre-resultados-semestrales-y-anuales-suministrada-a-la-sec/2024/sec-2023-annual-20-f-2023-en.pdf), as well as the section “Alternative performance measures” of this Banco Santander, S.A. (Santander) Q2 2024 Financial Report, published on 24 July 2024 (https://www.santander.com/en/shareholders-and-investors/financial-and-economic-information#quarterly-results). Underlying measures, which are included in this report, are non-IFRS measures.

The businesses included in each of our geographic segments and the accounting principles under which their results are presented here may differ from the businesses included and local applicable accounting principles of our public subsidiaries in such geographies. Accordingly, the results of operations and trends shown for our geographic segments may differ materially from those of such subsidiaries.

Non-financial information

This report contains, in addition to financial information, non-financial information (NFI), including environmental, social and governance-related metrics, statements, goals, commitments and opinions.

NFI is not audited nor reviewed by an external auditor. NFI is prepared following various external and internal frameworks, reporting guidelines and measurement, collection and verification methods and practices, which are materially different from those applicable to financial information and are in many cases emerging and evolving. NFI is based on various materiality thresholds, estimates, assumptions, judgments and underlying data derived internally and from third parties. NFI is thus subject to significant measurement uncertainties, may not be comparable to NFI of other companies or over time or across periods and its inclusion is not meant to imply that the information is fit for any particular purpose or that it is material to us under mandatory reporting standards. NFI is for informational purposes only and without any liability being accepted in connection with it except where such liability cannot be limited under overriding provisions of applicable law.

Forward-looking statements

Santander hereby warns that this report contains “forward-looking statements” as per the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Such statements can be understood through words and expressions like “expect”, “project”, “anticipate”, “should”, “intend”, “probability”, “risk”, “VaR”, “RoRAC”, “RoRWA”, “TNAV”, “target”, “goal”, “objective”, “estimate”, “future”, “commitment”, “commit”, “focus”, “pledge” and similar expressions. They include (but are not limited to) statements on future business development, shareholder remuneration policy and NFI.

While these forward-looking statements represent our judgement and future expectations concerning our business developments, results may differ materially from those anticipated, expected, projected or assumed in forward-looking statements.

In particular, forward looking statements are based on current expectations and future estimates about Santander’s and third-parties’ operations and businesses and address matters that are uncertain to varying degrees and may change, including, but not limited to (a) expectations, targets, objectives, strategies and goals relating to environmental, social, safety and governance performance, including expectations regarding future execution of Santander’s and third-parties’ (including governments and other public actors) energy and climate strategies, and the underlying assumptions and estimated impacts on Santander’s and third-parties’ businesses related thereto; (b) Santander’s and third-parties’ approach, plans and expectations in relation to carbon use and targeted reductions of emissions, which may be affected by conflicting interests such as energy security; (c) changes in operations or investments under existing or future environmental laws and regulations; (d) changes in rules and regulations, regulatory requirements and internal policies, including those related to climate-related initiatives; (e) our own decisions and actions including those affecting or changing our practices, operations, priorities, strategies, policies or procedures; (f) events that lead to damage to our reputation and brand; (g) exposure to operational losses, including as a result of cyberattacks, data breaches or other security incidents; and (h) the uncertainty over the scope of actions that may be required by us, governments and others to achieve goals relating to climate, environmental and social matters, as well as the evolving nature of underlying science and industry and governmental standards and regulations.

In addition, the important factors described in this report and other risk factors, uncertainties or contingencies detailed in our most recent Form 20-F and subsequent 6-Ks filed with, or furnished to, the SEC, as well as other unknown or unpredictable factors, could affect our future development and results and could lead to outcomes materially different from what our forward-looking statements anticipate, expect, project or assume.

				Main risks and uncertainties

Main risks and uncertainties

At the date of preparation of this management report, Grupo Santander considers that the important factors below (and others described elsewhere in this report), as well as other unknown or unpredictable factors, could affect our future development and results and could lead to outcomes materially different from what our forward-looking statements anticipate, expect, project or assume:

•General economic or industry conditions (e.g., an economic downturn; higher volatility in the capital markets; inflation or deflation; changes in demographics or consumer spending, investment or saving habits; and the effects of wars and conflicts (including the war in Ukraine and the conflict in the Middle East) or the outbreak of public health emergencies on the global economy) in areas where we have significant operations or investments.

•Climate-related conditions, regulations, targets and weather events.

•Exposure to market risks (e.g., risks from interest rates, foreign exchange rates, equity prices and new benchmark indices).

•Potential losses from early loan repayments, collateral depreciation or counterparty risk.

•Political instability in Spain, the UK, other European countries, Latin America and the US.

•Legislative, regulatory or tax changes (including regulatory capital and liquidity requirements), especially in view of the UK's exit from the European Union and greater regulation prompted by financial crises.

•Acquisition integration and challenges arising from deviating management’s resources and attention from other strategic opportunities and operational matters.

•Uncertainty over the scope of actions that may be required by us, governments and other to achieve goals relating to climate, environmental and social matters, as well as the evolving nature of underlying science and industry and governmental standards and regulations.

•Changes affecting our access to liquidity and funding on acceptable terms, especially due to credit spread shifts or credit rating downgrades for the entire Group or core subsidiaries.

•Damage to our reputation and to our brand.

•Exposure to operational losses, including as a result of cyberattacks, data breaches or other cybersecurity incidents.

These are not the only risks that the bank may face. Other unknown risks or those not considered relevant at this time, may materialize in the future.

Our geographic and business diversification protects us, to some extent, from adverse circumstances and enables us to resiliently face them. Although it is difficult to make estimations in the current environment, our strategy and business model are a clear competitive advantage.

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

Explanatory notes to the interim condensed consolidated financial statements for the six-month period ended 30 June 2024.

1.    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 2024 were authorised and approved by Grupo Santander's directors at the board of directors meeting held on 23 July 2024. Grupo Santander's consolidated annual accounts for year 2023 were approved by shareholders at Banco Santander annual general meeting on 22 March 2024.

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 2023 were authorised at the board of directors meeting on 19 February 2024 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 2023 and the consolidated results of its operations, and the consolidated cash flows in 2022. 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 21 February 2024, 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 taking into account the requirements of Circular 3/2018, of June 28, of the Securities and Exchange Commission (CNMV). These interim financial statements will be included in the Half-Yearly Financial Information corresponding to the first half of 2024 that the Group presents in accordance with the aforementioned 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 2023.

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 2023. 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.

106 January - June 2024

The accounting policies and methods used in preparing these interim financial statements are the same as those applied in the consolidated annual accounts for 2023 taking into account the standards and interpretations with effective application date during the first six months of 2024, which are detailed below:

•Amendment to IFRS 16 Lease Liability in a Sale and Leaseback requires a seller-lessee to subsequently measure lease liabilities arising from a leaseback without recognising any amount of the gain or loss that relates to the right of use retained. This new requirement does not prevent a seller-lessee from recognising in profit or loss any gain or loss relating to the partial or full termination of a lease. Applicable, retrospectively, from 1 January 2024.

•Classification of Liabilities, amendments to IAS 1 Presentation of Financial Statements, considering non-current liabilities those in which the entity has the possibility of deferring payment for more than 12 months from the closing date of the reporting period.

Likewise, an additional amendment to IAS 1 on the classification of liabilities with covenants as current or non-current has been approved, specifying that covenants that must be complied with after the reporting date do not affect the classification of liabilities and require additionally their respective breakdowns.

They should be applied retrospectively in accordance with the normal requirements of IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors. Applicable from 1 January 2024.

•IAS 7 Statement of Cash Flows and IFRS 7 Financial Instruments: Additional disclosures are required for companies entering into supplier financing arrangements. The objective of the new disclosures is to provide information on Supplier Finance Arrangements (SFA) that allows investors to evaluate the effects on an entity's liabilities, cash flows and liquidity risk exposure (effective from 1 January 2024).

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 June 2024 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 2024.

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 2023, except for those indicated in these interim financial statements due to the accounting standards and modifications that have come into effect during the first six months of the year 2024.

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:

•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;

•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;

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

•The useful life of the tangible and intangible assets;

•The measurement of goodwill impairment arising on consolidation;

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

•The fair value of certain unquoted assets and liabilities;

•The recoverability of deferred tax assets; and

•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, the levels of inflation and interest rates, as well as the resilience of the labour market being a priority monitoring focus due to the potential uncertainty generated in the Group's estimates.

The Group's management has evaluated in particular the uncertainties caused by the current environment in relation to credit, 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.

January - June 2024 107

In addition, the Group has applied in the interim financial statements a new theoretical exchange rate for the Argentine peso (1,499 pesos on 30 June 2024). This decision is due to the significant divergence that has been observed between the official exchange rate and other macroeconomic magnitudes, mainly inflation. The new theoretical exchange rate also reflects the implicit exchange rate observed in certain transactions ordered between market participants under the prevailing economic conditions, such as the repatriation of dividends from businesses in Argentina. This matter has not had a material impact in the Group’s interim financial statements.

During the six-month period ended 30 June 2024, there have been no additional significant changes in the estimates made at the end of 2023, other than those indicated in these interim financial statements.

d)    Contingent assets and liabilities

Note 25 to Grupo Santander's consolidated annual accounts for the year ended 31 December 2023 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 2023 to the date of formal preparation of these interim financial statements.

e)   Comparative information

The information in Note 12 related to segment information for March 2023 has been restated, in accordance with the new organizational structure 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 2023, 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 2023) and the impact of the appreciation/depreciation of the various currencies against the euro in the first six months of 2024: Mexican peso (-4.45%), US dollar (3.18%), Brazilian real (-9.73%), Pound sterling (2.38%), Chilean peso (-4.57%) and Polish zloty (0.82%); as well as the evolution of the average exchange rates between comparable periods: Mexican peso (6.12%), US dollar (-0.06%), Brazilian real (-0.21%), Pound sterling (2.52%), Chilean peso (-14.30%) and Polish zloty (7.11%).

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 six-month period ended 30 June 2024.

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 six-month period ended 30 June 2024.

h) Other information

On 28 December 2022, the law establishing a temporary levy on credit institutions and financial credit establishments was published in Spain. On 1 January 2024, an amount of EUR 335 million (EUR 224 million on 1 January 2023) was recorded under the heading "Other operating expenses" in the profit and loss account in accordance with IFRIC 21 due to this new tax.

i)    Events after the reporting period

From 1 July 2024 and up to the date of issuance of these interim financial statements corresponding to the first six months of 2024, there have been no relevant events other than those indicated in the interim financial statements.

2.    Grupo Santander

Appendices I, II and III to the consolidated annual accounts for the year ended 31 December 2023 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 2023, 2022 and 2021.

During the first six months of 2024, no significant operations have been carried out or those are pending execution at 30 June 2023.

b)   Earnings per share from continuing and discontinued operations

i. Basic earnings per share

Accordingly:

	30-06-2024	30-06-2023
Profit attributable to the Parent (EUR million)	6,059	5,241
Remuneration of contingently convertible preferred securities (CCPS) (EUR million)	(309)	(229)

Of which: from discontinued operations (euros)	—	—
from continuing operations (euros)	0.37	0.31

January - June 2024 109

ii. Diluted earnings per share

Diluted earnings per share for the period are calculated by dividing the net profit attributable to Grupo Santander for the first six months adjusted by the after-tax amount relating to the remuneration of contingently convertible preference shares recognised in equity and of perpetual liabilities contingently amortisable in their case by the weighted average number of ordinary shares outstanding during the period, excluding the average number of treasury shares and adjusted for all the dilutive effects inherent to potential ordinary shares (share options, warrants and convertible debt instruments).

	30-06-2024	30-06-2023
Profit attributable to the Parent (EUR million)	6,059	5,241
Remuneration of contingently convertible preferred securities (CCPS) (EUR million)	(309)	(229)

Provisions for other legal proceedings	1,305	1,359
Provision for customer remediation	535	454
Provision for restructuring	663	596
Other	1,044	869
	4,873	4,634

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 six months of 2024, for employment and other legal proceedings, in Brazil, provisions of EUR 267 million and EUR 140 million were recorded, making payments of EUR 202 million and EUR 100 million, respectively.

c)    Litigation and other matters

i. Tax-related litigation

At 30 June 2024 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 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.

•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.

•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 (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.

•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.

•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.

•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 2024, the appeal related to period 2009 to 2012 was 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.

•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 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.

120 January - June 2024

•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.

•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 March 2024, the CARF issued a favourable partial decision on the infraction notice of 2014/2015. 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 759 million, and for lawsuits that qualify as contingent liabilities is EUR 4,815 million.

•Banco Santander appealed before European Courts the Decisions 2011/5/CE of 28 October 2009 (First Decision), andc2011/282/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 definitively confirmed these Decisions. The dismissal of the appeal, that only affects these two decisions, had no impact on results.

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

ii. Non-tax-related proceedings

At 30 June 2024the main non-tax-related proceedings concerning the Group were as follows:

•Payment Protection Insurance (PPI): AXA France IARD and AXA France Vie (former GE Capital Corporation Group entities (GE Capital), known as Financial Insurance Company Ltd (FICL) and Financial Assurance Company Ltd (FACL), acquired by AXA SA in 2015) (together, AXA France) have brought a claim for GBP 552 million (EUR 651.3 million)(plus interest) against (i) Santander Cards UK Limited (former GE Capital entity 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) (together 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. AXA France reduced their claim from GBP 670 million (plus interest) to GBP 552 million (EUR 651.3 million) (plus interest) in their Re-Re-Amended Particulars of Claim dated 29 June 2023. The Santander Entities strongly refute the claim. Trial has been fixed on 3 March 2025.

There are ongoing factual issues to be resolved 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 definitive resolution of the matter. The provision recognized includes the best estimate of the Santander Entities’ liability to the specific portfolio.

•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 a number of county court claims and complaints in respect of its historical use of discretionary commission arrangements (DCAs) prior to the 2021 rule changes. In the context of the complaints made to the Financial Ombudsman Service (FOS) relating to such commission arrangements, the FCA announced on 11 January 2024 that it intends to use its powers under s166 of the Financial Services and Markets Act 2000 to review the historical use of DCAs between lenders and credit brokers (the “FCA Review”) and whether redress should be payable within all the industry. In line with the FCA's announcement, we have paused the response to customer complaints until at least 20 November 2024. A claim has been issued against SCUK, Santander UK plc and others in the Competition Appeal Tribunal (CAT), alleging that SCUK’s historical commission arrangements in respect of used car financing operated in breach of the Competition Act 1998. The CAT proceedings have been stayed until 25 November 2024 given the ongoing FCA Review. While it is possible that certain charges may be incurred in relation to the FCA's review or related existing or future county court claims, FOS complaints and the CAT proceedings, it is not considered that a legal or constructive obligation has been incurred in relation to these matters that would require a provision to be recognised at this stage. The resolution of such matters is not possible to predict with any certainty and there remain significant inherent uncertainties regarding the existence, scope and timing of any possible outflow which make it impracticable to disclose the extent of any potential financial impact.

•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.

January - June 2024 121

•Former employees of Banco do Estado de São Paulo S.A., Santander Banespa, Cia. de Arrendamiento Mercantil: class action filed by AFABESP (an association of retirees and former Banespa employees) claiming payment of a semi-annual bonus provided for in the Bank's bylaws. The final decision rendered on the merits was unfavorable to Santander. However, a favorable decision was subsequently rendered stating that each beneficiary of the decision shall file an individual lawsuit to receive the due amount.

Since the judgments adopted different positions for each case, a procedure called Incident for the Resolution of Repetitive Demands (IRDR) was commenced before the Regional Labor Court (TRT) with the purpose of establishing objective criteria regarding the arguments brought by the Bank, mainly the statute of limitations and limitation of payments until December 2006 (Plan V). On 11 March 2024, the IRDR was admitted for future judgment, and it was determined that all cases filed in São Paulo - Capital remained suspended from its second instance (TRT).

Finally, due to the divergence between the interpretation of the Federal Constitution, an Action for Allegation of Non- Compliance with a Fundamental Precept (ADPF) was also filed, so that the Federal Supreme Court (STF) settles the issue and indicates the correct statute of limitations to be used in the individual cases filed.

On 27 June 2024, an agreement was signed with the indication of a nominal and exhaustive list of 7,299 retirees who, according to the criteria presented by the Bank, are entitled to payment of the amounts related to semi-annual bonuses. The total value of the agreement will be BRL 2.7 billion (EUR 454.3 million); though it will ultimately depend on the individual and voluntary adherence of each beneficiary until 31 July 2024, period that may be extended until 15 August 2024. After the end of the voluntary adherence period, payments will be made in five instalments for living retirees (first installment on 20 October 2024) and a single installment for the heirs of the deceased people (31 October 2024). Considering that it is not possible to estimate the number beneficiaries and the total volume of the obligations that will be involved in the agreement; and that recognition of the obligation is conditional upon the adherence of the beneficiaries within the fixed period, as of 30 June 2024, the recorded provision is based on the estimation of the risk associated to individual claims against the Bank, being subject to the mentioned circumstances the future evolution of the provision and the final cost of the agreement.

•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 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 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'. On 30 June 2024, the provision recorded for the economic plan proceedings amounts to EUR 175.8 million.

•Floor clauses: as a consequence of the acquisition of Banco Popular Español, S.A.U. (Banco Popular), 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 included floor clauses in certain asset-side transactions with customers. In relation to this type of clauses, and after several rulings issued by the Court of Justice of the European Union (CJEU) and the Spanish Supreme Court, and the extrajudicial process established by the Spanish Royal Decree-Law 1/2017, of 20 January, Banco Popular 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. On 30 June 2024, after having processed most of the customer requests, the potential residual loss associated with ongoing court proceedings is estimated at EUR 53.67 million, amount which is fully covered by provisions.

•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 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 rendered five judgements in which it 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. Although four of these five judgments were initially appealed in cassation before the CJEU, in July 2023 one of the appellants withdrew his appeal. Therefore, only the appeals against three judgments are pending before the CJEU and in June 2024, the CJEU upheld the appeal in case C-551/22-P brought by the Commission. Appeals which are still pending in cassation refer to cases C-448/22-P, C-535/22-P and C-541/22-P.

122 January - June 2024

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 15 May, 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 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.

Regarding this judgment, several courts have referred additional preliminary rulings before the CJEU: (i) in December 2022 the Supreme Court requested three preliminary rulings in respect of its applicability to the holders of subordinated obligations, preferred stocks and subordinated bonds of Banco Popular; (ii) in April 2023, the First Instance Court 3 of Santa Coloma de Farners requested three preliminary rulings to the CJEU asking about pre-emptive subscription rights and the compatibility of the principles of proportionality and legal certainty with the bringing of legal actions by former holders of pre-emptive subscription rights and shares against the entity issuing the securities or against the entity succeeding it, which have been stayed by the CJEU until the preliminary rulings raised by the Supreme Court are resolved; and (iii) in November 2023, the Supreme Court requested another two preliminary rulings which supplement the ones requested in December 2022, regarding to a holder of subordinated bonds who filed a claim against Banco Popular before the resolution.

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. On 11 July 2024 the parties were summoned to file their indictment briefs within a 40-day term.

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. In view of the CJEU ruling of 5 May 2022, the Bank requested confirmation of the exclusion of its subsidiary civil liability status in this criminal proceeding. On 26 July 2022, the Court rejected this request stating that it is a matter to be determined at a later procedural time. This decision was confirmed on appeal by the Chamber of the National Court by judgment of 5 October 2022.

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 2022 represented 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 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.

•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.

January - June 2024 123

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. Existing provisions cover the estimated risk of loss.

•Universalpay Entidad de Pago, S.L. (Upay): has filed a lawsuit against Banco Santander, S.A. for breach of the marketing alliance agreement (MAA) and claims payment (EUR 1,050 million). The MAA was originally entered into by Banco Popular and its purpose is the rendering of acquiring services (point of sale payment terminals) for businesses in the Spanish market. The lawsuit was mainly based on the potential breach of clause 6 of the MAA, which establishes certain obligations of exclusivity, non-competition and customer referral. On 16 December 2022, the Court ruled in favour of the Bank and dismissed the plaintiff's claim in its entirety. The decision has been appealed before the Provincial Court of Madrid and the Bank has filed its opposition to Upay's appeal.

Considering the decision at first instance and following the analysis carried out by the Bank's external lawyers, with the best information available to date, it is considered that no provision needs to be registered.

•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 considering that certain contractual clauses in CHF-Indexed loan agreements were abusive. The CJEU 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.

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.

At the same time, the CJEU ruled that, under European law, there is no obstacle to the consumer being able to claim compensation from the bank beyond the return of the installments paid, but at the same time stipulated that such a claim should be evaluated in light of all the circumstances of the case, so that the consumer's possible benefits from the cancellation of the contract do not exceed what is necessary to restore the factual and legal situation in which he would have been without entering into the defective contract and do not constitute an excessive sanction for the entrepreneur (principle of proportionality).

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. The grounds of the above resolution are being awaited.

124 January - June 2024

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.

As of 30 June 2024, Santander Bank Polska S.A. and Santander Consumer Bank S.A. maintained a portfolio of loans affected by the legal risk connected with CHF mortgage for an approximate gross amount of PLN 5,739.4 million (EUR 1,332.2 million). As of 1 January 2022, in accordance with IFRS 9 and based on the new best available information, the accounting methodology was adapted so that 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.

As of the same date, the total value of adjustment to gross carrying amount in accordance with IFRS9 as well as provisions recorded under IAS37, amount to PLN 5,815.2 million (EUR 1,349.8 million) of which PLN 4,565.5 million (EUR 1,059.7 million) corresponds to adjustment to gross carrying amount under IFRS 9 and PLN 1,249.8 million (EUR 290.1 million) to provisions recognized in accordance with IAS 37. The adjustment to gross carrying amount in accordance with IFRS9 in the first 6 months of 2024 amounted to PLN 794.4 million (EUR 184 million), the additional provisions under IAS 37 amounted to PLN 511.8 million (EUR 118.6 million). Other costs related to the dispute amounted to PLN 239.3 million (EUR 55.4 million). These provisions represent the best estimate as at 30 June 2024. Santander Bank Polska and Santander Consumer Bank Poland will continue to monitor and assess appropriateness of those provisions.

In December 2020, the KNF presented a proposal for voluntary settlements between banks and borrowers under which CHF loans would be retrospectively settled as PLN loans bearing an interest rate based on WIBOR plus margin. The KNF continues to support the concept of offering such settlements by banks after the verdict of the CJEU on 15 June 2023. The Bank has prepared settlement proposals which consider both the key elements of conversion of home loans indexed to CHF, as proposed by the KNF Chairman, and the conditions defined internally by the Bank. The proposals are being presented to customers. This is reflected in the model which is currently used to calculate legal risk provisions.

•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.

On 29 June 2022, Santander México, within the framework of the amparo review filed by the Bank, requested the First Collegiate Court in Civil Matters of the Fourth Circuit of Nuevo León the recusal of two of the three Magistrates who rendered against Santander Mexico, which was resolved in favour of Santander Mexico. Plaintiffs requested the recusal of the third Magistrate who ruled with a dissenting vote against the recurso de amparo referred above and this was resolved in favour of Plaintiffs, and consequently the matter was referred to the Second Collegiate Court of the Fourth Circuit based in Nuevo León. The President of this Court considered that the Seventh Civil Chamber of the Superior Court of Justice of Nuevo León had fulfilled the Amparo granted to Mrs. Garza, therefore the Bank presented disconformity “inconformidad”, which was sent for resolution by the Second Collegiate Court of the Fourth Circuit based in Nuevo León. However, on 22 April 2024, the Bank asked the Supreme Court of Justice of the Nation to take up the matter. This has been accepted and consequently, the Supreme Court of Justice will resolve the matter.

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.

•URO Property Holdings, S.A. (before URO Property Holdings, SOCIMI SA): on 16 February 2022, legal proceedings were commenced in the Commercial Court of London against Uro Property Holdings, S.A. (Uro), a subsidiary of Banco Santander, S.A., by BNP Paribas Trust Corporation UK Limited (BNP) in its capacity as trustee on behalf of certain bondholders and beneficiaries of security rights. The litigation concerns certain terms of a financing granted to Uro which was supported by a bond issue in 2015. The claimant seeks a declaration by the Court and a monetary award against Uro, in connection with an additional premium above the nominal value of the financing repayment because of Uro having lost its status as SOCIMI (Sociedad Anónima Cotizada de Inversión Inmobiliaria), such loss causing the prepayment of the bond issue and, in the opinion of the claimant BNP, also the obligation to pay the additional premium by Uro. Uro denies being liable to pay that additional premium and filed its defense statement and a counterclaim against the claimant. The trial hearing has been scheduled for November and December 2024. Furthermore, Uro filed a summary judgement application for BNP's claim to be dismissed before trial. The dismissal of this application by the Commercial Court was confirmed by the Appeal Court. It is estimated that the maximum loss associated with this possible contingency, amounts to approximately EUR 250 million.

•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 September 2020, the Barcelona Court of Appeal, rendered a decision stating that the commencement (dies a quo) for the statute of limitation starts running from the day the consumer fully paid mortgage expenses. The judgment has been appealed to the Supreme Court, which referred a preliminary matter to the ECJ for the establishment of the dies a quo from which the limitation period for the refund action starts running (C-561/21).

On 25 January 2024 the ECJ rendered a judgment (joint cases C‑810/21 and C‑813/21) stating that Directive 93/13 must be fixed on a case-by-case basis by national courts based on the moment when the consumer was aware of the unfair nature of the clause and the legal consequences of such unfair nature. Further, on 25 April 2024, two additional judgments were rendered (cases C-561/21 and C-484/21) in which the ECJ stated that the dies a quo 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 ECJ 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 ECJ 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 ECJ by the First Instance Court No 8 of La Coruña.

In light of the foregoing, there are ongoing issues to be resolved which may have legal consequences. These issues create uncertainties which mean that it is difficult to reliably predict the outcome or the timing of the resolution of the matter. Therefore, the provision recognized includes the best estimate of Group’s liability to 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 June 2024, 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.

11.   Equity

In the six-month periods ended 30 June 2024 and 2023 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 2024 and 31 December 2023 consisted of EUR 7,747 million and EUR 8,092 million, respectively, represented by 15,494,273,572 and 16,184,146,059 shares of EUR 0.50 of nominal value each, respectively, and all of them of a unique class and series.

On 26 June 2024, there was a capital reduction amounting to EUR 165,652,500 through the redemption of 331,305,000 shares, corresponding to the share buyback program carried out between February and June 2024.

Likewise, on 30 January 2024, there was a capital reduction amounting to EUR 179,283,744 through the redemption of 358,567,487 shares, corresponding to the share buyback program for the year 2023 ended in January 2024.

The operations have not entailed the return of contributions to the shareholders as the Bank is the holder of the redeemed shares.

b)    Share premium

Includes the amount paid by the bank's shareholders in capital issuances in excess of par value.

As a result of the capital reductions described in Note 11.a, during the first semester of 2024, the share premium has been reduced by EUR 2,424 million corresponding to the difference between the purchase value of the shares amortised (EUR 2,769 million) and the nominal value of said shares (EUR 345 million) (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 345 million).

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 six months of 2024, the amount of actuarial losses (net of actuarial gains) has increased by EUR 59 million. The main impacts are:

•Increase of EUR 187 million in the cumulative actuarial losses relating to the Group´s businesses in the UK, mainly due to the behaviour of the asset portfolio and the variation in inflation hypotheses (both short and long term). These effects have been partially offset by the variation in the discount rate (increase from 4.63% to 5.15%).

•Decrease of 63 million in the cumulative actuarial losses relating to the Group's businesses in Brasil, mainly due to the discount rate variation (increase from 8.65% to 9.57% in the main pension plans, from 8.70% to 9.56% in the main medical plan). These effects have been partially offset by the effect of short-term inflation and the behaviour of the asset portfolio.

•Decrease of EUR 43 million in the cumulative actuarial losses relating to the Group's businesses in Mexico, mainly due to the increase in the discount rate (from 9.25% to 10.25%).

•Decrease of EUR 10 million in the cumulative actuarial losses relating to the Group's businesses in Germany, mainly due to the discount rate variation (increase from 3.57% to 3.74%).

The other modification in accumulated actuarial profit or losses is a decrease of EUR 12 million as a result of the evolution of exchange rates and other movements.

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 2024 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 appreciation of the Pound Sterling, US dollar and Mexican peso as well as the depreciation of the Brazilian real and Chilean peso (see Note 1.e).

Of this variation, a capital loss of EUR 335 million corresponds to the valuation at the closing exchange rate of goodwill for the first six months of 2024 (see Note 8).

12.   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.

On September 18, 2023, Grupo Santander announced that it is consolidating its retail & commercial and consumer activities across all markets under two new global businesses: Retail & Commercial and Digital Consumer Bank. The changes align these businesses with Santander’s at 30 June 2024, global model in Corporate & Investment Banking, Wealth Management & Insurance and Payments, helping the bank achieve the strategic goals.

The segments are split by business units in which profits are made and by geographic area. 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.

The Group's main level of segmentation, derived from its management model, consolidates the retail, commercial and consumer banking businesses of all markets under the umbrella of two new global business areas:

•Retail & Commercial Banking (Retail): new area that integrates the retail banking business (individuals) and commercial banking (SMEs and corporates), except for business originated in the consumer finance and the cards businesses.

•Digital Consumer Bank (Consumer): comprises all business originated in the consumer finance companies, plus Openbank, Open Digital Services (ODS) and SBNA Consumer.

•Corporate & Investment Banking (CIB): this business, which includes Global Transactional Banking, Global Banking (Global Debt Finance and Corporate Finance) and 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.

•Wealth Management & Insurance (Wealth): includes the asset management business (Santander Asset Management), the corporate unit of Private Banking and International Private Banking in Miami and Switzerland and the insurance business (Santander Insurance).

•Payments: digital payments solutions, providing global technology solutions for our 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).

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 six-month periods ended 30 June 2024 and 2023.

In addition to these operating units, which report by geographic area and businesses, Grupo Santander continues to maintain the area of Corporate Center, 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 six-month periods ended 30 June 2024 and 2023:

Liabilities under insurance contracts	—	17,592	17,592	—	17,799	17,799

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 six months of 2024 and 2023, 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 2023.

As the end of 30 June 2024, the CVA (Credit Valuation Adjustment) accounted for was EUR 274 million (a decrease of 6.5% compared to 31 December 2023) and adjustments of DVA (Debt Valuation Adjustment) was EUR 265 million (a decrease of 19.7% compared to the end of December 2023). The reduction is mainly due to a decline in the spread curves of the credit markets.

138 January - June 2024

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 instruments 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 2024 arising from models whose significant inputs are unobservable market data (level 3) amounted to EUR 160 million profit (EUR 178 million in the first six months of 2023).

January - June 2024 139

The table below shows the effect, at 30 June 2024 and 31 December 2023, 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:

17.2    Preference Shares and Preferred Securities

The following table shows the balance of the preference shares and preferred securities as of 30 June 2024 and 31 December 2023:

	30 June 2024	31 December 2023
	(Millions of Euros)
Preference shares	207	202
Preferred securities	8,281	9,081
Total at period-end	8,488	9,283

Both preference shares and preferred securities are recorded under the “Financial liabilities at amortized cost – Subordinated Liabilities” caption in the consolidated balance sheet as of 30 June 2024 and 31 December 2023.

Preference shares include the financial instruments issued by the consolidated companies which, although equity for legal purposes, do not meet the requirements for classification as equity in the financial statements. These shares do not carry any voting rights and are non-cumulative.

Preference shares include non-cumulative preferred non-voting shares issued by Santander UK plc.

Preferred securities include non-cumulative preferred non-voting securities issued by Banco Santander, S.A.

For the purposes of payment priority, preferred securities are junior to all general creditors and to subordinated deposits. The payment of dividends on these securities, which have no voting rights, is conditional upon obtaining sufficient distributable profit and upon the limits imposed by Spanish banking regulations on equity.

156 January - June 2024

Preference shares and preferred securities are perpetual securities and there is no obligation that requires the Group to redeem them. All securities have been fully subscribed by third parties outside the Group. In the consolidated balance sheets, these securities are shown net of any temporary transactions relating to liquidity guarantees.

For further information, see Note 23.c. to our consolidated financial statements in Part 1 of our 2023 Form 20-F filed with the SEC on 21 February 2024 and Note 9.b. to our consolidated financial statements in Part 1 of this report.

ITEM 1. PRESENTATION OF FINANCIAL AND OTHER INFORMATION

Accounting principles

Under Regulation (EC) No. 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 (a 'Member State') and whose securities are admitted to trading on a regulated market of any Member State must prepare their consolidated financial statements in conformity with the International Financial Reporting Standards previously adopted by the European Union ('EU-IFRS'). The Bank of Spain Circular 4/2004 of 22 December 2004 on Public and Confidential Financial Reporting Rules and Formats ('Circular 4/2004') required Spanish credit institutions to adapt their accounting systems to the principles derived from the adoption by the European Union of International Financial Reporting Standards. This Circular was repealed on 1 January 2018 by Bank of Spain Circular 4/2017, of 27 November 2017 on Public and Confidential Financial Reporting Rules and Formats ('Circular 4/2017'). Therefore, Grupo Santander (the 'Group' or 'Santander') is required to prepare its consolidated financial statements for the six-month period ended 30 June 2024 in conformity with EU-IFRS and Bank of Spain’s Circular 4/2017. Differences between EU-IFRS, Bank of Spain’s Circulars and International Financial Reporting Standards as issued by the International Accounting Standards Board ('IFRS-IASB') are not material. Therefore, we assert that the financial information contained in this report on Form 6-K complies with IFRS-IASB.

We have presented our financial information according to the classification format for banks used in Spain. We have not reclassified the line items to comply with Article 9 of Regulation S-X, as permitted by the rules and regulations of the US Securities and Exchange Commission ('SEC'). Article 9 is a regulation of the SEC that contains presentation requirements for bank holding company financial statements.

General information

Our consolidated financial statements are in Euros, which are denoted 'euro', 'euros', 'EUR' or '€' throughout this report. Also, throughout this report, when we refer to:

•'we', 'us', 'our', the 'Group', 'Grupo Santander', ‘Banco Santander’ or 'Santander', we mean Banco Santander, S.A. and its subsidiaries, unless the context otherwise requires;

•'dollars', 'US$' or '$', we mean United States dollars; and

•'pounds', 'GBP sterling' or '£', we mean United Kingdom pounds.

When we refer to 'net interest income' we mean 'interest income/(charges)'.

When we refer to 'staff costs' we mean 'personnel expenses'.

When we refer to 'profit before tax' we mean 'operating profit/(loss) before tax'.

When we refer to 'average balances' for a particular period, we mean the average of the month-end balances for that period, unless otherwise noted. We do not believe that monthly averages present trends that are materially different from trends that daily averages would show. In calculating our interest income, we include any interest payments we received on non-accruing loans if they were received in the period when due.

When we refer to 'loans', we mean loans, leases, discounted bills and accounts receivable, unless otherwise noted. The loan to value 'LTV' ratios disclosed in this report refer to LTV ratios calculated as the ratio of the outstanding amount of the loan to the most recent available appraisal value of the mortgaged asset. Additionally, if a loan shows signs of impairment, we update the appraisals which are then used to estimate allowances for loan losses.

When we refer to the non-performing loans ratio ('NPL ratio'), we mean credit impaired loans and advances to customers, customer guarantees and customer commitments granted divided by total risk (total loans and advances to customers, customer guarantees and customer commitments granted, including those that are credit impaired).

When we refer to 'credit impaired balances', unless otherwise noted, we mean credit impaired loans and advances to customers, customer guarantees and customer commitments granted.

When we refer to 'allowances for credit losses', unless otherwise noted, we mean allowances for expected credit losses of financial assets.

When we refer to 'perimeter effect', we mean growth or reduction derived from changes in the companies that we consolidate resulting from acquisitions, dispositions or other reasons.

Where a translation of foreign exchange is given for any financial data, unless otherwise noted, we use the exchange rates of the relevant period (as of the end of such period for balance sheet data and the average exchange rate of such period for income statement data) as published by the European Central Bank (ECB).

Management makes use of certain financial measures in local currency to help in the assessment of ongoing operating performance. These non-GAAP financial measures include the results of operations of our subsidiary banks located outside the eurozone, excluding the impact of foreign exchange. We analyse these banks’ performance on a local currency basis to better measure the comparability of results between periods. Because changes in foreign currency exchange rates have a non-operating impact on the results of operations, we believe that evaluating their performance on a local currency basis provides an additional and meaningful assessment of performance to both management and the company’s investors. Variances in financial metrics, excluding the exchange rate impact, are calculated by translating the components of the financial metrics to our Euro presentation currency using the same foreign currency exchange rate for

160 January - June 2024

both periods presented. For a discussion of the accounting principles used in translation of foreign currency-denominated assets and liabilities to Euros, see note 2(a) to our consolidated financial statements included in Part 1 of our Annual Report on Form 20-F for the year ended 31 December 2023 filed with the SEC on 21 February 2024 (the '2023 Form 20-F'). See more information in 'Alternative Performance Measures' under Part 1 of this report.

January - June 2024 161

ITEM 2. CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Banco Santander advises that this report on Form 6-K contains statements that constitute 'forward-looking statements' within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, information regarding:

•future business development;

•shareholders' remuneration policy;

•exposure to various types of market risks;

•management strategy;

•capital expenditures;

•earnings and other targets;

•asset portfolios; and

•non-financial information.

Forward-looking statements may be identified by words such as 'expect,' 'project,' 'anticipate,' 'should,' 'intend,' 'probability,' 'risk,' 'VaR,' 'RoRAC,' 'RoRWA,' 'TNAV,' 'target,' 'goal,' 'objective,' 'estimate,' 'future,' 'commitment,' 'commit,' 'focus,' 'pledge' and similar expressions which are found throughout this report on Form 6-K. We include forward-looking statements throughout this report on Form 6-K, including but not limited to, the 'Quantitative Analysis About Market Risk' section and the emissions and other climate-related performance data, statistics, metrics and/or targets. Forward-looking statements are not guarantees of future performance and involve risks and uncertainties, and actual results may differ materially from those in the forward-looking statements.

Written and/or oral forward-looking statements may also be made in the periodic reports to the US Securities and Exchange Commission, shareholder' and investors' reports, offering circulars, prospectuses, press releases and other written materials, and in oral statements made by our directors, officers or employees to third parties, including financial analysts.

You should understand that the following important factors, in addition to those discussed under 'Item 4. Risk Factors', 'Item 5. Information on the Company', 'Part 1. Consolidated Directors’ Report—Group Financial Information', 'Part 1. Consolidated Directors’ Report—Financial Information by Segments', and elsewhere in this report on Form 6-K, could affect our future results and could cause those results or other outcomes to differ materially from those anticipated in any forward-looking statement:

ITEM 3. SELECTED FINANCIAL DATA

We have selected the following financial information from our consolidated financial statements. You should read this information in connection with, and it is qualified in its entirety by reference to, our consolidated financial statements included in Part 1 of this report on Form 6-K.

From 1 January 2023 we apply retrospectively IFRS 17 'Insurance Contracts and amendments to IFRS 17' which did not have material equity impacts except for a balance sheet reclassification for an amount of approximately EUR 16 billion as of 31 December 2022 (EUR 18 billion as of 31 December 2021) from a portfolio of products registered in 'Customer deposits' to 'Liabilities covered by insurance or reinsurance contracts'. See note 1.b to our consolidated financial statements in Part 1 of our 2023 Form 20-F.

Our unaudited interim condensed consolidated financial statements reflect all adjustments that we believe are necessary to state such information fairly for the six months ended 30 June 2024 and 2023. All those adjustments are of a normal recurring nature. Our results for the six months ended 30 June 2024 are not necessarily indicative of what our results will be for the full year or any other period.

(A) Total customer funds includes customer deposits, mutual funds, pension funds and managed portfolios. See notes 21 and 35 to our consolidated financial statements included in Part 1 of our 2023 Form 20-F.

(B) Equals the sum of the amounts included at the end of each year as 'Shareholders’ Equity' and 'Other comprehensive income' as stated in our consolidated financial statements included in Part 1 of this report. We have deducted the book value of treasury stock from stockholders’ equity.

(C) Other Subordinated debt includes issuances by subsidiaries not guaranteed by Banco Santander, S.A. excluding preferred securities and preferred shares.

(D) In our consolidated financial statements included in Part 1 of this report, preferred securities and preferred shares are included under 'Subordinated liabilities'.

(E) Net Operating Income is used for the Group’s internal reporting and management reporting purposes but is not a line item in the statutory consolidated income statement. Net operating income equals the sum of 'Total income', 'Administrative expenses' and 'Depreciation and amortization' as stated in our consolidated financial statements included in Part 1 of this report.

(F) The Return on average stockholders’ equity ratio is calculated as profit attributable to the Parent divided by average stockholders’ equity.

(G) The Return on average tangible equity ratio (ROTE) is calculated as profit attributable to the Parent excluding goodwill impairment divided by the monthly average of: capital + reserves + retained earnings + other comprehensive income (excluding non-controlling interests) - goodwill - other intangible assets. We provide this non-GAAP financial measure as an additional measure to return on equity to provide a way to look at our performance which is closely aligned to our capital position.

(H) Consolidated profit and profit attributable to the Parent for the six months ended 30 June 2024 and 30 June 2023 have been annualized by doubling the recurring results, that is, assuming that non-recurring results registered during the first half of the year (if any) will not be repeated in the second half of the year. In the first half of 2024 and the first half of 2023 there were no non-recurring results. We believe that annualizing the profits by doubling only the recurring amounts presents an accurate picture of the evolution of our profitability. Consolidated profit and profit attributable to the Parent for the first half of any year are not necessarily indicative of the results for that full year.

166 January - June 2024

(I) Fully loaded CET1 ratios are calculated without application of the transitory IFRS 9 provisions nor the subsequent amendments introduced by Regulation 2020/873 of the European Union. The phased-in CET1 ratios reflect the application of the transitory provisions and subsequent amendments introduced by Regulation 2020/873 of the European Union.

(J) Reflect Bank of Spain classifications. These classifications differ from the classifications applied by US banks in reporting loans as non-accrual, past due, restructured and potential problem loans. See note 2 to our consolidated financial statements included in Part 1 of our 2023 Form 20-F.

(K) We disclose these ratios because our credit risk exposure comprises loans and advances to customers as well as contingent liabilities, all of which are subject to impairment and, therefore, allowances are taken in respect thereof.

(L) Credit impaired balances include credit impaired loans and advances, customer guarantees and customer commitments granted.

(M) Pay-out information for the six months ended 30 June 2024 and 2023 and for the year-end is not comparable. The interim figures for the six months ended 30 June 2024 and 2023 include in the numerator cash dividends paid during the first half of the year on account of that year (therefore zero, given that the first interim dividend on account of every year is paid in the second half of that year) while the full-year figures include in the numerator all cash dividends paid or to be paid on account of that year.

(N) Average number of shares has been calculated on a monthly basis as the weighted average number of shares outstanding in the relevant year, net of treasury stock.

(O) With regard to the 2021 shareholder remuneration policy, on 28 September 2021 the board announced its intention to pay out an interim distribution of approximately 40% of the Group's underlying profit, split in equal parts in cash dividend and share buybacks.

Interim remuneration. Accordingly, the board authorized the payment of an interim dividend of EUR 4.85 cents per share (i.e., 20% of the Group's underlying profit for the first half of 2021), in cash and charged against 2021 profits. The interim dividend was paid on 2 November 2021. The board also voted to launch the First 2021 Buyback Programme worth 841 million euros (20% of the Group's underlying profit for the first half of 2021) once the ECB approved it on 28 September 2021. The First 2021 Buyback Programme was completed on 26 November 2021, and resulted in the acquisition of a total of 259,930,273 shares.

Final remuneration. On 24 February 2022, pursuant to the 2021 shareholder remuneration policy, the board of directors voted to: (i) submit a resolution at the 1 April 2022 AGM (the '2022 AGM') to approve a final cash dividend in the gross amount of EUR 5.15 cents per share (approximately 20% of the Group’s underlying profit for the second half of 2021); and (ii) implement a Second 2021 Buyback Programme worth 865 million euros (approximately 20% of the Group’s underlying profit for the second half of 2021). After approval at the 2022 AGM, the cash dividend was paid on 2 May 2022, and the Second 2021 Buyback Programme was completed on 6 May 2022, resulting in the acquisition of a total of 286,309,445 shares. As a result, total shareholder remuneration totalled approximately EUR 3.4 billion, equivalent to approximately 40% of 2021 underlying attributable profit.

With regard to the remuneration policy against the 2022 earnings, the board continued the policy of allocating approximately 40% of the Group's underlying profit to shareholder remuneration, split in approximately equal parts in cash dividends and share buybacks.

Interim remuneration. On 27 September 2022, the board authorized the payment of an interim cash dividend against 2022 results of 5.83 euro cents per share (equivalent to approximately 20% of the Group's underlying profit in the first half 2022). The interim dividend was paid on 2 November 2022. The board also agreed to implement the First 2022 Buyback Programme worth approximately 979 million euros (approximately 20% of the Group's underlying profit in first half 2022) following the ECB approval on 17 November 2022. The First 2022 Buyback Programme was completed on 31 January 2023, and resulted in the acquisition of a total of 340,406,572 shares.

Final remuneration. On 27 February 2023, per the 2022 shareholder remuneration policy, the board of directors voted to: (i) submit a resolution at the 31 March 2023 AGM to approve a final cash dividend in the gross amount of 5.95 euro cents per share entitled to receive dividends (following the approval at the AGM, the dividend was paid on 2 May 2023); and (ii) implement a Second 2022 Buyback Programme worth 921 million euros, that commenced on 1 March 2023 and was completed on 21 April 2023, resulting in the acquisition of a total of 269,848,953 shares. After the above-mentioned actions, the shareholders' remuneration for 2022 amounted to 3,842 million euros (approximately 40% of the underlying profit in 2022) split in approximately equal parts in cash dividends (1,942 million euros) and share buybacks (1,900 million euros).

With regard to the remuneration policy against the 2023 earnings, the board followed a policy of allocating 50% of the Group’s reported profit, excluding non-cash, non-capital ratios impact items, to shareholder remuneration, distributed in approximately 50% in cash dividend and 50% in share buybacks.

Interim remuneration. On 26 September 2023, the board resolved to pay an interim cash dividend against the 2023 results of 8.10 euro cents per share entitled to the dividend (equivalent to approximately 25% of the Group's reported profit in the first half of 2023). The interim dividend was paid on 2 November 2023. The board also agreed to implement the First 2023 Buyback Programme worth approximately EUR 1,310 million (equivalent to approximately 25% of the Group's reported profit in the first half of 2023). The First 2023 Buyback Programme was completed on 25 January 2024, and resulted in the acquisition of a total of 358,567,487 shares.

Final remuneration. Under the 2023 shareholder remuneration policy, on 19 February 2024, the board of directors resolved to submit a resolution at the 22 March 2024 AGM to approve a final cash dividend in the gross amount of 9.50 euro cents per share entitled to dividends. Following the approval at the AGM, the dividend was paid from 2 May 2024. The board of directors also resolved to implement the Second 2023 Buyback Programme worth 1,459 million euros, which commenced on 20 February 2024 and was completed on 17 June 2024 resulting in the acquisition of a total of 331,305,000 shares. Once the above-mentioned actions were completed, total shareholder remuneration for 2023 amounted to 5,538 million euros (approximately 50% of the Group's reported profit in 2023), distributed in approximately 50% in cash dividend and 50% in share buybacks.

Remuneration per share for the six months ended 30 June 2024 and 2023 and for the year-end is not comparable. The remuneration per share disclosed for each financial year includes all dividends paid or to be paid on account of that financial year. The remuneration per share disclosed for the periods ended 30 June 2024 and 30 June 2023 includes the cash dividends paid in those periods; that is, EUR 9.50 cents per share paid during the first half of 2024 on account of the 2023 financial year, and EUR 5.95 cents per share paid during the first half of 2023 on account of the 2022 financial year.

ITEM 4. RISK FACTORS

For a description of risks associated with Banco Santander and the Group, see the section entitled 'Risk Factors' in our 2023 Form 20-F. Set out below are certain risk factors which could have a material adverse effect on Banco Santander’s and the Group’s business, operations, financial condition or prospects and cause future results to be materially different from expected results. The risks appearing below update and supplement certain risks highlighted in the 2023 Form 20-F. These risks should be read in conjunction with the other risks appearing in the 2023 Form 20-F and all of the other information appearing in this report on Form 6-K and should not be regarded as a complete and comprehensive statement of all potential risks and uncertainties that Banco Santander and the Group face. In addition, Banco Santander’s results could be affected by competition and other factors, there may be additional risks that Banco Santander currently considers not to be material or of which they are not currently aware, and any of these risks could also have a material adverse effect on our operations, financial condition or prospects. All of these factors are contingencies which may or may not occur and Banco Santander is not in a position to express a view on the likelihood of any such contingency occurring.

We are exposed to risk of loss from legal and regulatory proceedings.

We face risk of loss from legal and regulatory proceedings, including tax proceedings, that could subject us to monetary judgements, regulatory enforcement actions, fines and penalties. The current regulatory and tax enforcement environment in the jurisdictions in which we operate reflects an increased supervisory focus on enforcement, combined with uncertainty about the evolution of the regulatory regime, and may lead to material operational and compliance costs.

We are from time to time subject to regulatory investigations and civil and tax claims, and party to certain legal proceedings incidental to the normal course of our business, including, among others, in connection with conflicts of interest, lending and derivatives activities, relationships with our employees and other commercial, data protection or tax matters. In view of the inherent difficulty of predicting the outcome of legal matters, particularly where the claimants seek very large or indeterminate damages, or where the cases present novel legal theories, involve a large number of parties or are in the early stages of investigation or discovery, we cannot state with certainty what the eventual outcome of these pending matters will be or what the eventual loss, fines or penalties related to each pending matter may be.

The amount of our reserves in respect of these matters, which considers the likelihood of future cash outflows associated with each of such claims, is substantially less than the total amount of the claims asserted against us, and, in light of the uncertainties involved in such claims and proceedings, there is no assurance that the ultimate resolution of these matters will not significantly exceed the reserves currently accrued by us. As a result, the outcome of a particular matter may be material to our operating results for a particular period. As of 31 December 2023, we had provisions for taxes, other legal contingencies and other provisions for EUR 4,634 million (EUR 4,873 million as of 30 June 2024). See more information in note 10.b) to our 'Interim consolidated financial statements' included in Part 1 of this report.

For example, in Poland we are exposed to significant litigation in connection with CHF indexed and CHF denominated loans in which we are facing claims that those loans or clauses included in them are abusive. Whilst the Court of Justice of the European Union ('CJEU') and the Polish Supreme Court have issued several rulings on this matter (including the CJEU ruling of 15 June 2023), sufficient case law has not yet been developed. The case law of the Polish national courts implementing the CJEU rulings (including the ruling of 15 June 2023) and the possible position of the Polish Supreme Court will be crucial for the final assessment of the legal risk related to this matter. On 25 April 2024, the Supreme Court issued a resolution on CHF loans, in which it considered contract invalidation to be the primary consequence of finding abusive contractual clauses. At the same time, 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. The full text of the resolution has not yet been released. See note 10.c) to our 'Interim consolidated financial statements' included in Part 1 of this report.

As of the date of this report, it is not possible to predict the Polish Supreme Court’s and CJEU’s decisions on individual cases. As of 31 December 2023, Santander Bank Polska S.A. and Santander Consumer Bank S.A. maintained a portfolio of mortgages denominated in or indexed to CHF for an approximate gross amount of PLN 6,398.1 million or EUR 1,473.1 million (PLN 5,739.4 million or EUR 1,332.2 million as of 30 June 2024) and the total value of the adjustments to gross carrying amount in accordance with IFRS9 as well as the provisions recorded under IAS37, amount to PLN 5,030.3 million or EUR 1,158.2 million (PLN 5,815.2 million or EUR 1,349.8 million as of 30 June 2024). The provisions and adjustments recorded are deemed sufficient to cover the risks associated with the legal claims against us. However, in the event that we are required to make higher payments than estimated, either with respect to existing or new claims, there could be a significant adverse effect on our results and financial situation.

Any failure or disruption of our operational processes or systems, or data breaches and other security incidents with respect to our or our third-party vendors’ systems could adversely affect our business or reputation, and create significant legal, regulatory or financial exposure.

Like other financial institutions, in conducting our banking operations, we receive, manage, hold, transmit and otherwise process certain proprietary, sensitive or confidential information, including personal information of customers and employees, as well as a large number of assets. Accordingly, our business relies on our ability to process a large number of transactions efficiently and accurately, and on our ability to rely on our digital technologies, computer and email services, software and networks, as well as on the secure storage, transmission and other processing of proprietary confidential, sensitive and personal data, and other information using our computer systems and networks or those of our third-party vendors. Our operations must also comply with complex and evolving laws and regulations in the countries in which we operate. The proper and secure functioning of our financial controls, accounting and other data collection and processing systems is critical to our business and to our ability to compete effectively. Data breaches, data losses and other security incidents, including fraudulent withdrawal of money, can result from, among other things, inadequate personnel, inadequate or failed internal control processes and systems, or external events or actors that interrupt normal business operations and may include

January - June 2024 169

cyberattacks, disruptions, failures, unauthorized access or misuse, software bugs, server malfunctions, software and hardware failure, malware and ransomware, social engineering and phishing attacks, denial-of-service attacks, misconduct, fraud, and other events that could have a serious impact on us. We also face the risk that the design of our or our third-party vendors’ cybersecurity controls and procedures prove to be inadequate or are circumvented such that our data or client records are incomplete, not recoverable or not securely stored. Moreover, it is not always possible to deter or prevent employee errors or misconduct, and the precautions we take to detect and prevent this activity may not always be effective. Any material disruption or slowdown of our systems could cause information, including data related to customer requests, to be lost or to be delivered to our clients with delays or errors, which could reduce demand for our services and products, produce customer claims and materially and adversely affect us.

We prioritize early identification, monitoring and mitigation of risks (including those resulting from our interactions with third parties) in our goal to provide a resilient and secure operational environment. In this regard, although (i) we have policies, procedures and controls in place designed to safeguard proprietary, sensitive and confidential information, including personal information, (ii) we take protective technical measures and monitor and develop our systems and networks to protect our technology infrastructure, data and information from misappropriation or corruption, and (iii) we work with our clients, vendors, service providers, counterparties and other third parties to develop secure data and information processing, collection, authentication, management, usage, storage and transmission capabilities and to ensure the eventual destruction of proprietary, sensitive and confidential information, including personal information, we, our third-party vendors or other third parties with which we do business have been and may continue to be subject to cyberattacks and other cybersecurity incidents. For example, on 14 May 2024, we announced that we had become aware of an unauthorized access to a Santander database that included certain customer and employee information hosted by a third-party provider (the '2024 Unauthorized Access'). For more information on the legal and regulatory risks arising from the data privacy and cybersecurity laws and regulations we are subject to, which, among other things, impose certain obligations with respect to cyberattacks, data breaches, data losses, and other cybersecurity incidents, see risk factor ‘2.1.2 We are subject to extensive regulation and regulatory and governmental oversight which could adversely affect our business, operations and financial condition – Data privacy and cybersecurity’ in our 2023 Form 20-F).

The implementation of our cybersecurity policies, procedures, controls and technical measures is designed to reduce the risk of such cybersecurity incidents but does not guarantee full protection against potential threats or cyberattacks or a risk-free environment. This is especially applicable in the current global environment, with the war in Ukraine and the conflict in the Middle East resulting in an increased risk of cyberattacks, and other disruptions in response to, or retaliation for, the sanctions and costs imposed on Russia and certain other countries directly or indirectly involved in the wars. Additionally, the shift to remote work policies for a significant portion of our workforce, as they access our secure systems and networks remotely, and our customers’ increased reliance on digital banking products and other digital services, including mobile payment products, has also increased the risk of cyberattacks (see risk factor '1.3 The global covid-19 pandemic materially impacted our business, and the continuance of this pandemic or any future outbreak of any other highly contagious diseases or other public health emergencies, could materially and adversely impact our business, financial condition, liquidity and results of operations' in our 2023 Form 20-F).

While we generally perform cybersecurity due diligence on our key vendors, because we do not control our vendors and our ability to monitor their cybersecurity is limited, we cannot ensure the cybersecurity measures they take will be sufficient to protect any information we share with them. Due to applicable laws and regulations or contractual obligations, we may be held responsible for security breaches, cyberattacks or other similar incidents attributed to our vendors as they relate to the information we share with them.

In addition, we may also be impacted by cyberattacks against national critical infrastructures of the countries where we operate, such as telecommunications networks. Our information technology systems are dependent on such critical infrastructure and any cyberattack against such critical infrastructure could negatively affect our ability to service our customers. As we do not operate such critical infrastructure, we have limited ability to protect our information technology systems from the adverse effects of a cyberattack. For further information see the 'Risk, compliance and conduct management' chapter in Part 1 of our 2023 Form 20-F.

We have seen in recent years the information technology systems and networks of companies and organizations being increasingly targeted, and the techniques used to obtain unauthorized, improper or illegal access to such information technology systems and networks have become increasingly complex and sophisticated, including through the use of AI. Furthermore, such techniques change frequently and are often not recognized or detected until after they have been launched and can originate from a wide variety of sources, including organized crime, hackers, activists, terrorists, nation-states, nation-state supported actors and others, any of which may see their effectiveness enhanced by the use of AI. As attempted attacks continue to evolve in scope and sophistication, we may incur significant costs in order to modify or enhance our protective measures against such attacks, or to investigate or remediate any vulnerability or resulting breach, or in communicating cyberattacks or other security incidents to our customers, affected individuals or regulators, as applicable.

If we cannot maintain effective and secure proprietary, confidential, sensitive and personal data, or if we or our third-party vendors fall victim to successful cyberattacks, penetrations, compromises, breaches or circumventions of our information technology systems or networks, such as the 2024 Unauthorized Access, or experience other security incidents in the future, we may incur substantial costs and suffer other negative consequences, such as disruption to our operations, misappropriation of personal, proprietary, confidential or sensitive information, remediation costs (including liabilities for stolen assets or information, repairs of system damage, among others), increased cybersecurity protection costs, lost revenues arising from the unauthorized use of personal, proprietary, confidential or sensitive information or the failure to retain or attract our customers following an operational or security incident, litigation and legal risks (including claims from customers, employees or other third parties, regulatory action, reporting obligations, investigation, fines and penalties), increased insurance premiums, reputational damage affecting our customers’ and the investors’ confidence, as well as damages to our competitiveness, stock price and long-term shareholder value. In addition, our remediation efforts may not be successful, and we may not have adequate insurance to cover these losses. While we maintain insurance coverage, we cannot assure you that such coverage will be adequate or otherwise protect us from liabilities or damages with respect to claims alleging compromises of proprietary, confidential, sensitive or personal data or otherwise relating to data privacy and cybersecurity matters.

any future claim. Moreover, even when a failure of or interruption in our or our third-party vendors’ systems or facilities is resolved in a timely manner or an attempted cyberattack, data breach or security incident is successfully avoided or thwarted, substantial resources and management attention are expended in doing so, and to successfully avoid or resolve any such incidents, we may be required to take actions that could adversely affect customer satisfaction or retention, as well as harm our reputation.

Any of the cyberattacks, data breaches, data losses and other security incidents described above could have a material adverse effect on our business, financial condition and results of operations.

Credit, market and liquidity risk may have an adverse effect on our credit ratings and our cost of funds. Any downgrade in our credit rating would likely increase our cost of funding, require us to post additional collateral or take other actions under some of our derivative and other contracts and adversely affect our interest margins and results of operations.

Credit ratings affect the cost and other terms upon which we are able to obtain funding. Rating agencies regularly evaluate us, and their ratings of our debt are based on a number of factors, including our financial strength and conditions affecting the financial services industry. In addition, due to the methodology of the main rating agencies, our credit rating is affected by the rating of Spanish sovereign debt. If Spain’s sovereign debt is downgraded our credit rating would also likely be downgraded.

Any downgrade in our debt credit ratings would likely increase our borrowing costs and require us to post additional collateral or take other actions under some of our derivative and other contracts, and could limit our access to capital markets and adversely affect our commercial business. For example, a ratings downgrade could adversely affect our ability to sell or market some of our products, engage in certain longer-term and derivatives transactions and retain our customers, particularly customers who need a minimum rating threshold in order to invest. In addition, under the terms of certain of our derivative contracts and other financial commitments, we may be required to maintain a minimum credit rating or terminate such contracts or require the posting of collateral. Any of these results of a ratings downgrade could reduce our liquidity and have an adverse effect on us, including our operating results and financial condition.

We have the following ratings by the major rating agencies as of the report dates indicated below:

Banco Santander, S.A.
Rating agency	Long term	Short term	Last report date	Outlook
Fitch Ratings	A- (Senior A)	F2 (Senior F1)	Mar 2024	Stable
Moody's	A2	P-1	Apr 2024	Positive
Standard & Poor's	A+	A-1	Apr 2024	Stable
DBRS	A (High)	R-1 (Middle)	Sep 2023	Stable

Santander UK, plc
Rating agency	Long term	Short term	Last report date	Outlook
Fitch Ratings	A+	F1	May 2024	Stable
Moody's	A1	P-1	Feb 2024	Stable
Standard & Poor's	A	A-1	Jun 2023	Stable

Banco Santander (Brasil)		(Foreign currency)
Rating agency	Long term	Short term	Last report update	Outlook
Moody's	Ba1	-	May 2024	Positive
Standard & Poor's	BB	B	Dec 2023	Stable

We conduct substantially all of our material derivative activities through Banco Santander and Santander UK. We estimate that as of 31 December 2023, if all the rating agencies were to downgrade Banco Santander’s long-term senior debt ratings by one notch, we would be required to post up to EUR 210 million in additional collateral pursuant to derivative and other financial contracts. A hypothetical two-notch downgrade would result in a further requirement to post up to EUR 178 million in additional collateral. We estimate that as of 31 December 2023, if all the rating agencies were to downgrade Santander UK’s long-term credit ratings by one notch, and thereby trigger a short-term credit rating downgrade, this could result in contractual outflows from Santander UK’s total liquid assets of £1.2 billion (equivalent to EUR 1.4 billion) of cash and additional collateral that Santander UK would be required to post under the terms of secured funding and derivatives contracts. A hypothetical two-notch downgrade would result in a further outflow of £0.8 billion (equivalent to EUR 0.9 billion) of cash and collateral under secured funding and derivatives contracts.

January - June 2024 171

While certain potential impacts of these downgrades are contractual and quantifiable, the full consequences of a credit rating downgrade are inherently uncertain, as they depend on numerous dynamic, complex and inter-related factors and assumptions, including market conditions at the time of any downgrade, whether any downgrade of our long-term credit rating precipitates downgrades to our short-term credit rating, and assumptions about the potential behaviours of various customers, investors and counterparties. Actual outflows could be higher or lower than the preceding hypothetical examples, depending upon certain factors including which credit rating agency downgrades our credit rating, any management or restructuring actions that could be taken to reduce cash outflows and the potential liquidity impact from loss of unsecured funding (such as from money market funds) or loss of secured funding capacity. Although unsecured and secured funding stresses are included in our stress testing scenarios and a portion of our total liquid assets is held against these risks, a credit rating downgrade could still have a material adverse effect on us.

In addition, if we were required to cancel our derivatives contracts with certain counterparties and were unable to replace such contracts, our market risk profile could be altered.

There can be no assurance that the rating agencies will maintain the current ratings or outlooks. In general, the future evolution of Santander's ratings is linked, to a large extent, to the general macroeconomic outlook which includes the impact of the continuance or escalation of the war in Ukraine and of the conflict in the Middle East on our asset quality, profitability and capital. Failure to maintain favourable ratings and outlooks could increase our cost of funding and adversely affect interest margins, which could have a material adverse effect on us.

ITEM 5. INFORMATION ON THE COMPANY

5.1. Average balance sheets and interest rates

The following tables include, by domicile of the Group entity at which the relevant asset or liability is accounted for, our average balances and interest rates for the six months ended 30 June 2024 and 2023. Domestic balances are those of Group entities domiciled in Spain, which reflect our domestic activities, and international balances are those of Group entities domiciled outside of Spain, which reflect our foreign activities.

To better understand the behaviour of average balance sheets and interest rates, we have split our foreign activities into ‘International – Mature markets’ which include Europe (except for Spain and Poland) and the United States and ‘International – Developing markets’ which include South America, Mexico and Poland.

You should read the following tables and the tables included under '—Changes in Net Interest Income/(charges)—Volume and Rate Analysis' and '—Assets—Earning Assets—Yield Spread' considering the following:

•We have included in interest income loan arrangement fees and other similar items;

•We have not recalculated tax-exempt income on a tax-equivalent basis because the effect of doing so would not be significant;

•We have included income and expenses from interest-rate hedging transactions as a separate line item under interest income and expenses if these transactions qualify for hedge accounting under IFRS-IASB. If these transactions do not qualify for such treatment, we have included income and expenses on these transactions elsewhere in our income statement. See Note 2 to our consolidated financial statements included in Part 1 of our 2023 Form 20-F for a discussion of our accounting policies for hedging activities;

•We have stated average balances on a net basis, netting our allowances for credit losses; and

•All average data have been calculated as the simple average of month-end balances over the relevant date range, which is not significantly different from having used daily averages.

Average loans outstanding	1,059,566		1,055,023		966,690		1,070,909		1,060,301

For the purpose of calculating the net charge-offs during the period to average loans outstanding ratio, net charge-offs consist of charge-offs against credit loss allowance less recoveries of loans previously charged-off and loans outstanding refer to gross loans and advances to customers. Reverse repurchase agreements are collateralized and therefore cannot be charged-off. Net charge-offs to average loans outstanding ratios at 30 June 2024 and 30 June 2023 reflect year-to-date net charge-offs annualized.

The table above excludes the 'fixed payments' of our derivatives since derivative contracts executed by the Group apply close-out netting across all outstanding transactions, that is, these agreements provide for settlements to be made on a maturity or settlement date for the differences that arise, and as such, the obligation to be settled in the future is not fixed at the present date and is not determined by the fixed payments.

January - June 2024 183

ITEM 7. RISK DISCLOSURES

Higher-Risk Loans

Grupo Santander’s loan portfolio is focused mainly on retail banking with a medium-low risk profile, with a broad diversified geographical footprint well-balanced between emerging and developed markets. In addition, our business diversification between customer segments is a key factor to remain resilient. Grupo Santander does not have any significant exposure to higher-risk loans.

Some of the Group’s portfolios require specific monitoring due to the inherent nature of their business and particular risk profile, including for instance the auto loans business in the consumer subsidiary in the US (SC USA). Other less relevant portfolios in terms of size are also explicitly monitored through the risk appetite and the applicable monitoring policies.

It should be noted that, at 30 June 2024, 65% of the Group’s net customer loans are secured, mostly by real estate collateral.

Mortgages to individuals represent approximately 34% of the Group’s loan book, with low risk profile and low non-performing ratios, along with appropriate provisions coverage. Among other factors, this is due to the fact that these are mainly first residence mortgage loans, which are subject to a rigorous assessment of credit risk and affordability. The admission process evaluates the current and future payment capacity of the customer, evaluating if the client’s disposable income will be sufficient to meet the loans’ instalments even in a more stressed but feasible scenario.

Certain mortgage portfolios that may present higher risks (interest only, flexible loans, loans with loan-to-value greater than 100% or buy to let), are subject to even stricter lending policies to mitigate their risks. Nevertheless, they represent a low percentage of the Group’s portfolio, and their performance is continuously monitored to guarantee close and effective control.

Changes in Practices

In the first half of 2024, Grupo Santander conducted its business in an environment marked by inflation’s soft landing (high inflation slowly declining or without improving in core inflation) in several geographies, ongoing geopolitical tensions and the different electoral processes in Europe and Latin America.

Grupo Santander reinforced the monitoring of all risks. In general, the most significant impacts are related to higher interest rates for longer, which may potentially affect credit growth; new cyberattacks and other cybersecurity incidents, such as the 2024 Unauthorized Access, which may also derive in an increase of reputational risk; the evolution and potential impacts of the Swiss francs mortgage portfolio in Poland, following the ruling of the CJEU on 15 June 2023 and the resolution issued by the Supreme Court on 25 April 2024; and the CRE portfolio, especially the Office segment, which has been impacted by persistent lower demand as a result of both the structural and the pandemic-related changes, mainly in the US market.

In addition, due to future implementation of regulatory requirements, Santander is assessing to improve the disclosure regarding the management of risks that may arise from the Group’s relationship with end-users, employees and suppliers.

Other

Grupo Santander's exposure to complex structured instruments and assets is very limited; this is a reflection of our robust risk culture and prudent risk management.

Santander uses credit derivatives to cover loans and to serve our customer needs regarding their trading activities in financial markets. Trading volume is small in terms of our notional value (0.4% of total counterparty risk notional value as of 30 June 2024) and is subject to a solid set of internal controls and procedures to minimize operational risk.

Exposures related to complex structured assets

We have a very limited exposure to complex structured assets. See 'Quantitative Analysis About Market Risk' below.

Quantitative Analysis About Market Risk

A.    Activities subject to market risk and types of market risk

Activities exposed to market risk encompass transactions where risk is assumed as a consequence of potential changes in interest rates, inflation rates, exchange rates, stock prices, credit spreads, commodity prices, volatility and other market factors, the liquidity risk from our products and markets, and the balance sheet liquidity risk. Therefore, they include trading risks and structural risks.

•Interest rate risk arises from changes in interest rates that could adversely affect the value of a financial instrument, a portfolio or the Group as a whole. It can affect loans, deposits, debt securities, most assets and liabilities held for trading and derivatives.

•Inflation rate risk originates from changes in inflation rates that could adversely affect the value of a financial instrument, a portfolio or the Group as a whole. It can affect instruments such as loans, debt securities and derivatives, where the returns are linked to future inflation values or a change in the current rate.

•Exchange rate risk is the possibility of loss in the value of a position not denominated in the base currency to shifts in exchange rates. A long or open position in a foreign currency may produce a loss if it depreciates against the base currency. Exposures affected by this risk include non-euro currencies investments in subsidiaries and transactions in foreign currency.

184 January - June 2024

•Equity risk is the possibility of loss from open positions in equities to adverse movements in their market prices or expectations about future dividends. This affects positions in shares, stock market indices, convertible bonds and derivatives with shares as the underlying asset (put, call, equity swaps, etc.).

•Credit spread risk is the possibility of loss from open positions in fixed income securities or credit derivatives to adverse movements in credit spread curves or recovery rates associated with specific issuers and types of debt. The spread is the yield difference between financial instruments with a quoted margin over other benchmark instruments, mainly the internal rate of return (IRR) of government bonds and interbank interest rates.

•Commodity price risk is the possibility of loss from adverse movements in commodity prices. Our exposure to this risk is minor and stems mainly from commodity derivatives.

•Volatility risk is the possibility of loss caused by adverse movements in the volatility of interest rates, exchange rates, shares, credit spreads and other factors affecting the value of our portfolio. It is inherent to all financial instruments whose value is affected by volatility (especially options contracts).

These market risks can be partly or fully mitigated with derivatives such as options, futures, forwards and swaps. However, there are other types of market risks that require more complex hedging:

•Correlation risk is the possibility of loss due to an adverse change in the relationship between risk factors (correlation) of the same type (e.g. two exchange rates) or different type (e.g. an interest rate and a commodity price).

•Market liquidity risk originates when Santander or a subsidiary cannot reverse or close a position without an impact on the market price or the transaction cost. Market liquidity risk can arise from a reduction in market makers or institutional investors, the execution of a large volume of transactions or market instability. It could also increase depending on how exposures are distributed among products and currencies.

•Pre-payment or cancellation risk originates when mortgages, deposits and other on-balance-sheet instruments give holders the option to buy or sell them, altering future cash flows. Potential mismatches on the balance sheet pose a risk since cash flows may have to be reinvested at an interest rate that is potentially lower (assets) or higher (liabilities).

•Underwriting risk arises when an entity underwrites or places securities and other types of debt and assumes the risk of having to acquire issued securities partially if buyers have not taken them up.

In addition to the above market risks, balance sheet liquidity risk (unlike market liquidity risk) is the possibility of meeting payment obligations late or at an excessive cost. Losses may be caused by forced sales of assets or margin impacts due to the mismatch between expected cash inflows and outflows.

On the other hand, pension and actuarial risks also depend on shifts in market factors. Further details are provided in this chapter.

Finally, in recent years there has been an increased focus on climate and environmental risks, which arise from the possibility that changes in climate may adversely affect the value of a financial instrument, a portfolio or the Group as a whole. Changes in climate include both extreme weather scenarios as well as gradual climate change and other situations where there is environmental degradation. This risk may have an impact both on financial instruments value or portfolios and on Santander's liquidity. The Group measures this risk through stress scenarios for both market and liquidity risk.

We aim to comply with the Basel Committee’s Fundamental Review of the Trading Book, and the EBA's Guidelines on the management of interest rate risk arising from non-trading book activities. Through several projects, we aim to provide risk managers and control teams with the best tools to manage market risks under the right governance framework for the models we use, to report risk metrics, and help satisfy requirements on these risks.

B.    Trading market risk management

Management limits and control system

The market risk function daily monitoring makes sure market risk positions remain within approved limits. It assesses the performance of, and major changes in, market risk metrics, and distributes regular reports to senior management and other internal and external stakeholders so market risk activities can be properly monitored.

The market risk limits are established based on different metrics and are intended to cover all activities subject to market risk from many perspectives, applying a prudent approach. The main ones are:

• Value at Risk (VaR) and Stressed VaR limits

• Limits of equivalent and/or nominal positions

• Interest rate sensitivity limits

• Vega limits

• Delivery risk limits for short positions in securities (fixed income and securities)

• Limits to constrain the volume of effective losses or protect results generated during the period:

• Loss trigger

• Stop loss

January - June 2024 185

• Credit limits:

• Total exposure limit

• Jump to default limit by issuer

• Others

• Limits for origination transactions

Those general limits include sub-limits that make the structure granular enough to control market risks from Santander's trading operations. We monitor subsidiaries' positions daily, checking changes in portfolios and at trading desks in order to detect events that may necessitate immediate mitigation.

The Group establishes global approval and control limits, global approval limits with local control, and local approval and local control limits. They are requested by each subsidiary's business manager in consideration of particular circumstances of the business, budgetary targets and the risk/reward ratio. Limits are then approved by risk bodies according to internal governance processes.

Subsidiaries must comply with the approved limits. On the day a limit breach occurs, subsidiary business managers must provide a written explanation with an action plan and corrective measures, such as reducing the position within the limits or formulating a strategy that justifies raising limits.

Methodologies

a) Value at Risk (VaR)

Value at Risk (VaR), our standard methodology for managing and controlling market risk, measures maximum expected loss with a certain confidence level over a given time.

For standard historical simulation, the confidence level is 99% and the time horizon is one day. We also make statistical adjustments efficiently to incorporate recent developments affecting our levels of risk. Our time frame is two years or at least 520 days from the reference date of the VaR calculation. We report the higher of two VaR figures we calculate daily. One applies an exponential decay factor that allocates less weight to the oldest observations; the other has the same weight for all observations.

We also simultaneously calculate Value at Earnings (VaE). It measures the maximum potential gain with a certain level of confidence and specific time frame under the same methodology for VaR.

VaR by historic simulation has many advantages as a risk metric. It states a portfolio's market risk in a single figure according to market movements, without assumptions about functions, forms or correlations between market factors.

However, the VaR metric has some limitations, regardless of the methodology to calculate it. In particular:

• As VaR calculation has a certain confidence level, it does not indicate the levels of possible losses beyond it.

• The liquidity horizon of some products in the portfolio is longer than that of the VaR model.

• VaR is a static measure of risk subject to significant (albeit unlikely) changes in the following day.

Historical simulation methodology also has limitations:

• High sensitivity to time frame used;

• Inability to capture plausible high-impact events if these do not occur during the time frame used.

• Valuation parameters with no market input (such as correlations, dividend and recovery rates).

• Slow adjustment to new volatility and correlation, as the weighting of the newest and oldest data is the same.

Using Stressed VaR and expected shortfall (ES) help overcome some of these limitations. We calculate VaR with exponential decay, apply conservative valuation adjustments, and regularly conduct analyses and backtesting to assess the accuracy of the VaR calculation model.

b) Stressed VaR (sVaR) and expected shortfall (ES)

We calculate sVaR daily for our main portfolios with the same methodology as for VaR, with these exceptions:

• We use a window of 260 observations (as opposed to 520 for VaR) over a continuous period of stress on a portfolio. For each portfolio, we review the history of a subset of selected market risk factors based on expert judgement and the most significant positions in the books.

• Unlike VaR, we obtain sVaR by using the percentile with uniform weighting, and not with the higher of the percentiles with exponential and uniform weightings.

To calculate the ES we estimate expected potential loss above the level obtained from VaR and assign uniform weights to all observations. Unlike VaR, ES has the advantage of capturing the risk of large losses with a low probability (tail risk) and being a sub-additive metric. According to the Basel Committee, an ES with a 97.5% confidence interval delivers a level of risk similar to VaR at a 99% confidence interval.

c) Scenario analysis

186 January - June 2024

Santander's risk measures are based on normal market conditions, price stability, sufficient liquidity and other assumptions used in daily risk management and decision-making. However, it is possible that extreme movements and strong unforeseen changes will not be properly anticipated. Therefore, we run scenario analyses, which prove important to predict the outcome of a wide range of risks and estimate the capital needed to absorb any losses in case such unexpected events occur.

These stress scenarios are important to estimate future risk, overcome the limitations of models and historical data, support liquidity and capital plans, report on risk tolerance levels and develop risk reduction and contingency plans under stress conditions.

We regularly calculate and analyse stress scenarios for our subsidiaries with trading activities which include historical scenarios, hypothetical scenarios and reverse stress test scenarios.

d) Analysis of positions, sensitivities and results

Santander uses positions to quantify the market values of transactions in the portfolio, grouped by main risk factor and considering the delta value of any futures or options. We can express risk positions in our subsidiaries' base currency and in the currency used for standardized information. We monitor positions daily to detect incidents and correct them immediately.

Measurements of market risk sensitivity estimate the variation of an instrument or portfolio's market value to changes in a risk factor with analytical approximations given through partial derivatives or a complete revaluation of the portfolio.

The daily profit and loss (P&L) statement prepared by the market risk function is an excellent indicator of the impact of changes of financial variables on portfolios.

e) Derivatives activities and credit management

We run controls over derivative activities and credit management daily with specific measures due to their atypical nature. We control and monitor underlying asset's sensitivity to price movements (Delta and Gamma), volatility (Vega) and time (Theta). Also, we systematically review measurements such as sensitivity to the spread, jump-to-default and concentrations of positions by rating.

For credit risk in trading portfolios, we also calculate Incremental Risk Charge (IRC), an additional metric recommended by the Basel Committee and current regulations. IRC covers default risks and rating migrations not adequately captured in VaR through variations in credit spreads.

We apply this metric to government and corporate bonds, derivatives on bonds (forward, options, etc.) and credit derivatives (credit default swaps, asset backed securities, etc.). We calculate IRC using direct measurements of loss distribution tails at an appropriate percentile (99.9%), over a one-year horizon. We follow the Montecarlo methodology, applying one million simulations.

f) Credit Valuation Adjustment (CVA) and Debt Valuation Adjustment (DVA)

Santander calculates trading portfolio results with credit valuation adjustment (CVA) and debit valuation adjustment (DVA). The CVA is for over the-counter (OTC) derivatives and results from the risk associated with the credit exposure assumed with each counterparty.

The CVA for a particular counterparty is the total CVA for all its maturities. To calculate it, we consider inputs such as expected exposure, loss given default, probability of default and a discount factor curve.

DVA is similar to CVA but results from the risk our counterparties assume in OTC derivatives traded with us.

January - June 2024 187

C.    Key metrics (Trading Market Risk)

In the first half of 2024, markets remained volatile supported by the geopolitical tensions maintained in Ukraine and Middle East coupled with elections in several countries and the European Union Parliament. Additionally, market focus remained on inflation evolution and the uncertainty over the timing and path of monetary easing cycle from major Central Banks. In this challenging environment, Santander’s trading risk profile remained low, in line with previous years, due to the fact that risks of trading activities arise mainly from activities with customers in non-complex instruments, concentrated in hedging of interest rate and exchange rate risks.

Value at Risk (VaR) analysis

During the first half of 2024, Santander continued its strategy of focusing its trading activity on customer business, minimising where possible, exposure to directional risk in net terms and maintaining its diversification by geography and risk factor.

Evolution of VaR for the first half of 2024.

EUR million. VaR at 99% over a one day horizon.

VaR during the first half of 2024 fluctuated between EUR 11.6 million and EUR 22.5 million, with an average VaR for the period of EUR 16.8 million and ending in June at EUR 14.9 million. Most of the time , daily VaR was above the average of the last three years, mainly due to market volatility spikes and a larger exposure to interest rates.

The following histogram shows the distribution of risk in terms of VaR in the first six months of 2024. The accumulation of days with levels up to EUR 21.5 million (98%) is shown. Values higher than EUR 21.5 million (2%) largely occur in periods affected by temporary spikes in volatility or punctual increases of exposure, mainly in interest rates and exchange rates.

Gauging and backtesting measures

Regulations dictate that the VaR model should accurately capture market risks. VaR uses statistical techniques under normal conditions. Therefore, for a certain confidence level and for a defined time horizon, the estimated maximum loss can differ from actual losses. Santander reviews and contrasts the VaR calculation model on a regular basis to verify its accuracy.

The market risk function runs tests such as internal backtesting, VaR contrast measures and hypothetical portfolio analysis for subsidiaries covered by the internal market risk model. For subsidiaries with an approved internal model, we also perform regulatory backtesting to count overshootings (when daily loss or profit exceeds VaR or VaE) affecting the calculation of market risk regulatory capital requirements.

Our backtesting assesses the general quality and effectiveness of the risk measurement model and compares the daily VaR/VaE obtained on D-1 with these P&Ls obtained on D:

•Economic P&L: is calculated on the basis of end-of-day mark-to-market or mark-to-model values. This test checks whether the VaR/VaE methodology used to measure and aggregate risk is appropriate.

•Actual P&L: is calculated based on the difference between the portfolio's end-of-day value and actual value at the end of the subsequent day. It includes the profit and loss stemming from intraday operations, minus fees, commissions, and net interest income. It is used to count regulatory overshootings.

•Hypothetical P&L: is calculated daily by comparing the portfolio's end-of-day value and its value at the end of subsequent day, assuming unchanged positions. It does not account for the time effect to be consistent with VaR. This backtesting helps us make sure portfolios are regularly subject to an intraday risk not reflected in closing positions and therefore, not reflected in VaR. We also use it to count regulatory overshootings.

•Theoretical P&L: is calculated with the market risk calculation engine, without intraday results, changes in portfolio positions or time (theta). We use it exclusively to test the quality of our internal VaR model.

We run regulatory backtesting on our subsidiaries every day. We also run internal (not regulatory) backtesting daily, weekly and monthly based on the granularity of a given portfolio level. The number (or proportion) of overshootings we register is one of the most intuitive indicators of a model's goodness of fit. We calculate regulatory backtesting for one year (250 days) and at a VaR confidence level of 99%.

In the last twelve months, for Hypothetical P&L backtesting and for the total portfolio, there were no overshootings in VaR at 99%. There was an overshooting in VaE at 99% on 13 December as a result of the devaluation of the Argentine peso. The results are consistent with the assumptions specified in the VaR calculation model.

190 January - June 2024

Derivatives risk management

Our derivatives business primarily involves selling investment products and hedging risks for customers. Our risk management aims to keep open net risk as low as possible. Transactions include options on equities, fixed income and exchange rates, mainly in Spain, Brazil and the UK.

Risk of derivatives (in terms of VaR Vega at 99%, over a one-day horizon) moved in the first half of 2024 in a range between EUR 1.9 million and EUR 4.2 million, with an average value of EUR 2.7 million.

Santander's exposure to complex structured instruments and assets is very limited, this reflects our risk culture and prudent risk management. The Risk Appetite of the Group limits the total of level 3 assets and liabilities (those which fair value is calculated using significant inputs not observable in market data) to 5% of Group's total assets and liabilities measured at fair value. On the other hand, at the end of the first half of 2024, our exposures in hedge funds was EUR 106 million (all indirect), acting as counterparty in derivative transactions. We analyse the risk related to this type of counterparty on a case-by-case basis, setting collateralization ratios based on each fund's characteristics and assets.

Our policy on approving new derivatives transactions remains extremely prudent and conservative. It is closely monitored by senior management.

Scenario analysis

Various stress scenarios were calculated and analysed regularly in the first half of 2024 (at least monthly) for all the trading portfolios.

Worst-case scenario

This is a hypothetical scenario which combines movements in risk factors with their respective volatilities. The construction of these scenarios is based on historical volatilities, assuming a variation of ±3 and ± 6 daily standard deviations, irrespective of the historical correlation between them. Its aim is to analyse the risk profile and potential maximum losses of trading portfolios, identifying the most unfavourable scenario.

At the end of June 2024, the stress test revealed that the economic loss in trading portfolios would be EUR 92 million (market price) if the stress movements in the worst-case scenario materialized in the market. The loss would mainly affect Europe (mostly in interest rate under a scenario of increases, in equities under a scenario of decreases and in exchange rates under a scenario of depreciation of the Euro).

Stress scenario: worst case. EUR million

	Interest rate	Equities	Exchange rate	Credit spread	Commodities	Total
Total trading	(37.0)	(17.9)	(28.6)	(8.1)	0.0	(91.6)
Europe	(21.7)	(15.7)	(12.8)	(7.7)	0.0	(57.9)
North America	(7.4)	(0.5)	(6.0)	0.0	0.0	(13.9)
South America	(7.8)	(1.8)	(9.8)	(0.4)	0.0	(19.8)

Other global stress test scenarios

‘Abrupt crisis’: an ad-hoc scenario with sharp market movements in all risk factors: rise in interest rate curves, sharp falls in stock markets, strong appreciation of USD against other currencies, increase in volatility and credit spreads and default of main debt and equity positions.

‘Subprime crisis’: historical scenario based on 2007-2008 events arising from the US subprime mortgage crisis. This financial crisis led to a sharp increase in volatility and a sharp reduction in liquidity in all financial markets worldwide. The worst 1-day and 10-day market shocks are identified for each market risk factor.

‘Forward Looking Scenario’: a plausible hypothetical scenario based on current portfolios and expert judgement regarding the short term expected movements in market risk factors that may negatively affect trading positions.

‘EBA adverse scenario’: hypothetical scenario based on the adverse macroeconomic scenario applied to all market risk factors, as proposed by the EBA to perform the 'EU wide stress test' exercise every two years.

'Covid-19 crisis': scenario based in the sharp movements in the financial markets as a result of the health crisis. Its calculation is based on the identification of the 10-day period with higher losses in the trading portfolio during the first half of 2020.

Reverse stress test scenarios, which identify market variable shifts that can lead to a loss that will endanger our survival. They complement traditional stress scenarios and help signal business vulnerabilities, hidden risks and interactions between risk factors. They begin with a known stress result (such as a failure to achieve certain capital, liquidity or solvency ratios) and identify extreme scenarios.

D.    Structural balance sheet risk management

January - June 2024 191

System for controlling limits

Like with trading market risk, annual limits planning sets limits for balance sheet structural risks based on risk appetite.

The main limits we use are:

• Balance sheet structural interest rate risk:

• Limit on net interest income (NII) over a 1-year horizon.

• Limit on the sensitivity of the economic value of equity (EVE).

• Limit on the market value variations of ALCO portfolios under stress scenarios.

• Structural exchange rate risk:

• Limit on the potential impact of the net foreign currency permanent position in the Core Capital Ratio.

• Limit on the individual hedge required by each currency.

Financial Management must explain why limits or sub-limit breaches occur and provide action plans to correct them.

Methodologies

a) Structural interest rate risk

We analyse the potential impact of changes in interest rate levels on EVE and NII. Depending on the changes in rates, impacts will be different and therefore various subtypes of interest rate risk need to be monitored and managed, such as repricing, curve or basis risk, among others.

Based on the balance sheet interest rate position and the market situation and outlook, financial actions (such as transacting positions or setting interest rate for products we market) may be needed to achieve our desired risk profile.

The suite of metrics we use to monitor interest rate risks includes the sensitivity of NII and EVE to changes in interest rates:

- Net interest income (NII) sensitivity

NII is the difference between income from interest on assets and the cost of liabilities in the banking book over a typical one-to three-year horizon (one year being standard in Santander). NII sensitivity is the difference between the NII calculated under a selected scenario and the NII calculated under a base scenario. There can be as many NII sensitivities as scenarios. This metric helps identify short-term risk and it is complementary to EVE sensitivity. Scenarios of -100 basis points parallel changes and +100 basis points are considered, choosing the worst one (hereinafter figures show the result under these scenarios).

-Economic value of equity (EVE) sensitivity

EVE is the difference between the net current value of assets and the net current value of outstanding liabilities in the banking book at a certain point in time. EVE sensitivity is the difference in EVE calculated under a selected scenario and under a base scenario. There can be as many EVE sensitivities as scenarios considered. This metric helps identify long-term risk and it is complementary to NII sensitivity. Scenarios of -100 basis points parallel changes and +100 basis points are considered, choosing the worst one (hereinafter figures show the result under these scenarios).

b) Interest rate models

Interest rate risk metrics consider the behaviour of financial products under stressed scenarios where uncertainty is common and contractual terms may not be met. We have methodologies that help to explain products' behaviour. Key interest rate risk models are:

-Treatment of liabilities without stated maturity

Our model uses variables such as stable and unstable volumes, the rate of settlement over time and the difference between customer rates and market rates to model non-maturity account balances.

- Pre-payment treatment for certain assets

Pre-payment risk mainly affects fixed-rate mortgages in subsidiaries where contractual rates are low relative to market levels. We model this risk and include it in risk appetite metrics.

192 January - June 2024

c) Structural foreign exchange rate risk/hedging of results

We monitor these activities daily via position measurements, VaR and results.

d) Structural equity risk

We monitor these activities monthly via position measurements, VaR and results.

E. Structural balance sheet risks key metrics

Consistent with previous years, the market risk profile of Santander's balance sheet remained moderated in the first half of 2024 in terms of asset, shareholders’ equity and net interest income volumes.

Each subsidiary's finance division manages its interest rate risk from commercial banking and is responsible for managing structural risk caused by fluctuating interest rates.

We use statistical models to measure interest rate risk and different strategies to manage structural risk with interest rate instruments, such as fixed income bond portfolios and derivative instruments to keep the risk profile within risk appetite.

Structural interest rate risk

Europe

At the end of June, the EVE sensitivity of our balance sheets in Europe was positive to interest rate decreases. In the case of NII, the sensitivity of our balance sheets in Santander Spain, Santander UK, Santander Poland and Santander Portugal, was positive to interest rate increases.

Exposure levels in all countries was moderate in relation to the annual budget and capital levels.

At June 2024, considering the scenarios previously mentioned, the most significant risk of NII sensitivity was in the Euro interest rate curve at EUR 783 million, followed by the British pound at EUR 128 million, the US dollar at EUR 116 million and the Polish zloty at EUR 61 million, all relating to the risk of rate decreases.

In the case of NII, our core South American balance sheets (Brazil, Chile and Argentina) were positioned for interest rate decreases. In the first half of 2024, exposure levels in all countries was moderate in relation to the annual budget and capital levels.

At the end of June, the most significant risk to NII was located in Brazil (EUR 132 million) and Chile (EUR 11 million).

In the first half of 2024, exposure levels in all countries were moderate in relation to the annual budget and capital levels.

At the end of June, the most significant risk to NII was mainly in the US (EUR 153 million).

Net interest income (NII) sensitivity

Structural foreign exchange rate risk/hedging of results

Our structural exchange rate risk is driven by exposures in foreign currencies related to permanent financial investments, their results and related hedges.

Our dynamic management of this risk seeks to limit the impact on the core capital ratio from foreign exchange rate movements. At the end of June 2024, the largest exposures of permanent investments (with their potential impact on equity) were (in order), in Brazilian reais, US dollars, UK pounds sterling, Mexican pesos, Polish zlotys and Chilean pesos. We hedge some of these positions (which are permanent in nature) with foreign exchange-rate derivatives.

The Financial division is responsible for foreign exchange rate risk management, hedging expected results and dividends in subsidiaries where the base currency is not the euro.

Structural equity risk

We hold equity positions in its banking book as equity instruments or equity stakes depending on the percentage owned or control.

We diversified the equity portfolio in the banking book at the end of June 2024 between securities in Spain, China, Morocco, Poland and other countries. Most of the portfolio invests in the finance and insurance industries, and also include real estate.

Structural equity positions have market risk exposure. We calculate VaR for these positions with market price data series or proxies. By the end of June 2024, the VaR at 99% over a one-day time horizon was EUR 141 million (EUR 171 and EUR 195 million at the end of 2023 and 2022, respectively).

F.    Pension and actuarial risks

Pension risk

Santander assumes the financial, market, credit and liquidity risks in the assets and investments of defined benefit employee pension funds, as well as the actuarial risks from pension obligations. Our main goal in the pension risk control and management is to identify, measure, monitor, mitigate and disclose all sources of pension risk.

We annually estimate combined losses in assets and liabilities under a stress scenario that includes changes in interest rates, exchange rates, inflation, stock markets, real estate prices and credit spread.

Actuarial risk

Actuarial risk stems from biometric changes in the life expectancy of defined benefit pension scheme beneficiaries; from life insurance holders; unforeseen non-life insurance payments; and unexpected changes in holders' behaviour when filing claims covered in insurance contracts.

We distinguish these actuarial risks:

Life liability risk is the risk of loss if fluctuations in risk factors changes the value of pension liabilities:

•Mortality/longevity risk: risk of loss in variations in insured parties' estimated probability of death/survival parties changes the value of liabilities.

•Morbidity risk: risk of loss if insured parties' estimated probability of disability/incapacity changes the value of liabilities.

•Surrender/lapse risk: risk of loss caused by changes in the value of liabilities because of the early termination or changes in policyholders' rights in regard to surrender, extraordinary contributions and/or paid up options.

•Expense risk: risk of loss if an adverse deviation in expected expenses changes the value of liabilities.

•Catastrophe risk: losses if catastrophic events increase pension liabilities.

Non-life liability risk is the risk of losses from changes in the value of Santander's non-life benefit liabilities with employees, caused by fluctuations in related risk factors:

•Premium risk: loss from insufficient premiums to pay for claims that might be made in the future.

January - June 2024 195

•Reserve risk: loss from insufficient reserves for unsettled claims, including related costs.

•Catastrophe risk: losses if catastrophic events increase non-life liabilities.

G.    Management of structural liquidity

Structural liquidity management aims to finance the Group’s recurring activity in optimum conditions of maturity and cost and avoid assuming undesired liquidity risks.

Given the retail nature of the Group, commercial branches have continued taking deposits following the selective financing strategy of the Group considering their costs.

Notwithstanding the aforementioned, the different Group companies have maintained frequent issuance activity in the different wholesale funding markets during the year in order to continue strengthening their liquidity position and presence in the markets, taking advantage of favourable market conditions. The Group issued in the first half of 2024 €30,323 million of medium- and long-term issues, of which €12,053 million was senior debt, €6,272 million was covered bonds and €11,998 million were TLAC (Total Loss Absorbing Capacity) eligible instruments of which €8,092 million was senior non-preferred, €2,406 million was subordinated debt and €1,500 million was additional Tier 1. Maturities of medium- and long-term debt amounted to €25,682 million in the first half of 2024, of which €15,587 million was senior debt, €3,349 million was covered bonds, €5,053 million was senior non-preferred, €0 million was subordinated debt and €1,693 million was additional Tier 1. Additionally, securitizations placed in the market amounted to €13,713 million while maturities followed a similar pattern.

In short, all these actions have contributed to strengthen the Group’s balance sheet and capital base and helped to maintain an appropriate liquidity position.

The main aspects in relation to structural management of liquidity during the first half of 2024 were:

•Adequate position of structural liquidity. We are essentially a retail bank. Therefore, customer deposits are the main source of funds in our financing structure. These deposits, together with capital and similar instruments, enable us to address most of the Group’s liquidity needs.

Diversification of markets and instruments to obtain liquidity. We have an active presence in several wholesale markets, across the different countries where the Group operates. This strategy limits our dependence on specific markets and allows us to maintain a comfortable capacity of recourse to the markets.

•As of 30 June 2024, the balance sheet of the Group was solid, as befits the Group’s retail nature. Lending, which accounted for around 70% of net assets, was fully financed by customer deposits and medium and long-term funding. The Group has an adequate structure of medium and long-term issuances, well diversified by products (including, senior debt, senior non-preferred debt, covered bond, subordinated debt and additional Tier 1) with a moderately conservative maturity (4.3 years as of 30 June 2024). All of this results in moderate needs of recourse to short term wholesale funding at the Group level.

Excluding securitizations, most medium- and long-term issuance activity has been concentrated on the Eurozone and the UK, with a moderate contribution from USA.

On 30 June 2024, the Group's structural liquidity surplus stood at €316.7 billion on a consolidated basis. This surplus is based mainly on fixed income securities (€232.1 billion), equities (€19.7 billion) and net lent deposits to central banks and credit entities (€106.1 billion), partially offset by short term funding balance (€41.2 billion).

•High capacity to obtain liquidity on the balance sheet. The reserve includes deposits in central banks and cash, unencumbered sovereign debt, undrawn credit lines granted by central banks, as well as other assets eligible as collateral and other undrawn credit lines in official institutions (FHLB, etc.), all of which reinforce the solid liquidity position of the Group and its subsidiaries. As a proof of this sound and ample liquidity position, the Group as a whole exhibits both a Liquidity Coverage Ratio (LCR) well above the 100% regulatory limit and a Net Stable Funding Ratio (NSFR), also well above 100%. Compared with 2023 year-end, LCR has slightly diminished and NSFR has not substantially changed during the first half of 2024.

•Access to wholesale markets for liquidity based on short and long-term ratings.

•Independence of the subsidiaries in funding within a coordinated liquidity management. The most important subsidiaries obtain their funding in wholesale markets in accordance with their needs, establishing their own liquidity and contingency plans, without recourse to lines from the parent Bank to finance their activity.

•Moderate use of assets as security for structural balance-sheet funding sources that has not materially changed since the end of 2023.

Santander Group performs a continuous internal process to ensure the adequacy of both, its liquidity position and the management, measurement, monitoring and control of its liquidity risk (Group Internal Liquidity Adequacy and Assessment Process). However, in accordance to Santander’s model for liquidity management based on autonomous subsidiaries, this adequacy assessment process in fact encompasses separate adequacy assessment processes at the subsidiary level (each of them an Internal Liquidity Adequacy and Assessment Process), which are complemented and overseen by corporate processes, governance and coordination functions.

196 January - June 2024

All these processes, which are forward looking and integrated into the decision-making and management process, risk management and risk appetite, liquidity planning and overall strategy, have the ultimate objective of ensuring that the Group's entities have and will have adequate liquidity resources to meet their obligations under both normal and stressed conditions and over an appropriate set of time horizons, taking into account all material sources of liquidity risk.

January - June 2024 197

Introduction, basis of presentation of the interim condensed consolidated financial statements and other information

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 2024 were authorised and approved by Grupo Santander's directors at the board of directors meeting held on 23 July 2024. Grupo Santander's consolidated annual accounts for year 2023 were approved by shareholders at Banco Santander annual general meeting on 22 March 2024.

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 2023 were authorised at the board of directors meeting on 19 February 2024 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 2023 and the consolidated results of its operations, and the consolidated cash flows in 2022. 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 21 February 2024, 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 taking into account the requirements of Circular 3/2018, of June 28, of the Securities and Exchange Commission (CNMV). These interim financial statements will be included in the Half-Yearly Financial Information corresponding to the first half of 2024 that the Group presents in accordance with the aforementioned 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 2023.

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 2023. 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 2023 taking into account the standards and interpretations with effective application date during the first six months of 2024, which are detailed below:

•Amendment to IFRS 16 Lease Liability in a Sale and Leaseback requires a seller-lessee to subsequently measure lease liabilities arising from a leaseback without recognising any amount of the gain or loss that relates to the right of use retained. This new requirement does not prevent a seller-lessee from recognising in profit or loss any gain or loss relating to the partial or full termination of a lease. Applicable, retrospectively, from 1 January 2024.

•Classification of Liabilities, amendments to IAS 1 Presentation of Financial Statements, considering non-current liabilities those in which the entity has the possibility of deferring payment for more than 12 months from the closing date of the reporting period.

Likewise, an additional amendment to IAS 1 on the classification of liabilities with covenants as current or non-current has been approved, specifying that covenants that must be complied with after the reporting date do not affect the classification of liabilities and require additionally their respective breakdowns.

They should be applied retrospectively in accordance with the normal requirements of IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors. Applicable from 1 January 2024.

•IAS 7 Statement of Cash Flows and IFRS 7 Financial Instruments: Additional disclosures are required for companies entering into supplier financing arrangements. The objective of the new disclosures is to provide information on Supplier Finance Arrangements (SFA) that allows investors to evaluate the effects on an entity's liabilities, cash flows and liquidity risk exposure (effective from 1 January 2024).

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 June 2024 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 2024.

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 2023, except for those indicated in these interim financial statements due to the accounting standards and modifications that have come into effect during the first six months of the year 2024.

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:

•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;

•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;

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

•The useful life of the tangible and intangible assets;

•The measurement of goodwill impairment arising on consolidation;

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

•The fair value of certain unquoted assets and liabilities;

•The recoverability of deferred tax assets; and

•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, the levels of inflation and interest rates, as well as the resilience of the labour market being a priority monitoring focus due to the potential uncertainty generated in the Group's estimates.

The Group's management has evaluated in particular the uncertainties caused by the current environment in relation to credit, 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 addition, the Group has applied in the interim financial statements a new theoretical exchange rate for the Argentine peso (1,499 pesos on 30 June 2024). This decision is due to the significant divergence that has been observed between the official exchange rate and other macroeconomic magnitudes, mainly inflation. The new theoretical exchange rate also reflects the implicit exchange rate observed in certain transactions ordered between market participants under the prevailing economic conditions, such as the repatriation of dividends from businesses in Argentina. This matter has not had a material impact in the Group’s interim financial statements.

During the six-month period ended 30 June 2024, there have been no additional significant changes in the estimates made at the end of 2023, other than those indicated in these interim financial statements.

d)    Contingent assets and liabilities

Note 25 to Grupo Santander's consolidated annual accounts for the year ended 31 December 2023 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 2023 to the date of formal preparation of these interim financial statements.

e)   Comparative information

The information in Note 12 related to segment information for March 2023 has been restated, in accordance with the new organizational structure 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 2023, 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 2023) and the impact of the appreciation/depreciation of the various currencies against the euro in the first six months of 2024: Mexican peso (-4.45%), US dollar (3.18%), Brazilian real (-9.73%), Pound sterling (2.38%), Chilean peso (-4.57%) and Polish zloty (0.82%); as well as the evolution of the average exchange rates between comparable periods: Mexican peso (6.12%), US dollar (-0.06%), Brazilian real (-0.21%), Pound sterling (2.52%), Chilean peso (-14.30%) and Polish zloty (7.11%).

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 six-month period ended 30 June 2024.

g)    Materiality

b)   Earnings per share from continuing and discontinued operations

i. Basic earnings per share

Basic earnings per share for the period are calculated by dividing the net profit attributable to Grupo Santander for the first six months adjusted by the after-tax amount relating to the remuneration of contingently convertible preference shares recognised in equity by the weighted average number of ordinary shares outstanding during the period, excluding the average number of treasury shares held in the period.

Accordingly:

	30-06-2024	30-06-2023
Profit attributable to the Parent (EUR million)	6,059	5,241
Remuneration of contingently convertible preferred securities (CCPS) (EUR million)	(309)	(229)
	5,750	5,012
Of which:
Profit or Loss from discontinued operations (non controlling interest net) (EUR million)	—	—
Profit or Loss from continuing operations (CCPS net) (EUR million)	5,750	5,012
Weighted average number of shares outstanding	15,664,707,190	16,279,041,269
Basic earnings per share (euros)	0.37	0.31
Of which: from discontinued operations (euros)	—	—
from continuing operations (euros)	0.37	0.31

ii. Diluted earnings per share

Diluted earnings per share for the period are calculated by dividing the net profit attributable to Grupo Santander for the first six months adjusted by the after-tax amount relating to the remuneration of contingently convertible preference shares recognised in equity and of perpetual liabilities contingently amortisable in their case by the weighted average number of ordinary shares outstanding during the period, excluding the average number of treasury shares and adjusted for all the dilutive effects inherent to potential ordinary shares (share options, warrants and convertible debt instruments).

Accordingly, diluted earnings per share were determined as follows:

	30-06-2024	30-06-2023
Profit attributable to the Parent (EUR million)	6,059	5,241
Remuneration of contingently convertible preferred securities (CCPS) (EUR million)	(309)	(229)

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 2023 to 30 June 2024, is mainly due to benefit and premium payments or contributions (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 2024 and at 31 December 2023 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
	30-06-2024	31-12-2023
Provisions for taxes	714	745
Provisions for employment-related proceedings (Brazil)	612	611
Provisions for other legal proceedings	1,305	1,359
Provision for customer remediation	535	454
Provision for restructuring	663	596
Other	1,044	869
	4,873	4,634

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 six months of 2024, for employment and other legal proceedings, in Brazil, provisions of EUR 267 million and EUR 140 million were recorded, making payments of EUR 202 million and EUR 100 million, respectively.

c)    Litigation and other matters

i. Tax-related litigation

At 30 June 2024 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 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.

•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.

•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 (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.

•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.

•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.

•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 2024, the appeal related to period 2009 to 2012 was 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.

•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 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.

•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.

•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 March 2024, the CARF issued a favourable partial decision on the infraction notice of 2014/2015. 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 759 million, and for lawsuits that qualify as contingent liabilities is EUR 4,815 million.

•Banco Santander appealed before European Courts the Decisions 2011/5/CE of 28 October 2009 (First Decision), andc2011/282/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 definitively confirmed these Decisions. The dismissal of the appeal, that only affects these two decisions, had no impact on results.

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

ii. Non-tax-related proceedings

At 30 June 2024the main non-tax-related proceedings concerning the Group were as follows:

•Payment Protection Insurance (PPI): AXA France IARD and AXA France Vie (former GE Capital Corporation Group entities (GE Capital), known as Financial Insurance Company Ltd (FICL) and Financial Assurance Company Ltd (FACL), acquired by AXA SA in 2015) (together, AXA France) have brought a claim for GBP 552 million (EUR 651.3 million)(plus interest) against (i) Santander Cards UK Limited (former GE Capital entity 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) (together 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. AXA France reduced their claim from GBP 670 million (plus interest) to GBP 552 million (EUR 651.3 million) (plus interest) in their Re-Re-Amended Particulars of Claim dated 29 June 2023. The Santander Entities strongly refute the claim. Trial has been fixed on 3 March 2025.

There are ongoing factual issues to be resolved 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 definitive resolution of the matter. The provision recognized includes the best estimate of the Santander Entities’ liability to the specific portfolio.

•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 a number of county court claims and complaints in respect of its historical use of discretionary commission arrangements (DCAs) prior to the 2021 rule changes. In the context of the complaints made to the Financial Ombudsman Service (FOS) relating to such commission arrangements, the FCA announced on 11 January 2024 that it intends to use its powers under s166 of the Financial Services and Markets Act 2000 to review the historical use of DCAs between lenders and credit brokers (the “FCA Review”) and whether redress should be payable within all the industry. In line with the FCA's announcement, we have paused the response to customer complaints until at least 20 November 2024. A claim has been issued against SCUK, Santander UK plc and others in the Competition Appeal Tribunal (CAT), alleging that SCUK’s historical commission arrangements in respect of used car financing operated in breach of the Competition Act 1998. The CAT proceedings have been stayed until 25 November 2024 given the ongoing FCA Review. While it is possible that certain charges may be incurred in relation to the FCA's review or related existing or future county court claims, FOS complaints and the CAT proceedings, it is not considered that a legal or constructive obligation has been incurred in relation to these matters that would require a provision to be recognised at this stage. The resolution of such matters is not possible to predict with any certainty and there remain significant inherent uncertainties regarding the existence, scope and timing of any possible outflow which make it impracticable to disclose the extent of any potential financial impact.

•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.

•Former employees of Banco do Estado de São Paulo S.A., Santander Banespa, Cia. de Arrendamiento Mercantil: class action filed by AFABESP (an association of retirees and former Banespa employees) claiming payment of a semi-annual bonus provided for in the Bank's bylaws. The final decision rendered on the merits was unfavorable to Santander. However, a favorable decision was subsequently rendered stating that each beneficiary of the decision shall file an individual lawsuit to receive the due amount.

Since the judgments adopted different positions for each case, a procedure called Incident for the Resolution of Repetitive Demands (IRDR) was commenced before the Regional Labor Court (TRT) with the purpose of establishing objective criteria regarding the arguments brought by the Bank, mainly the statute of limitations and limitation of payments until December 2006 (Plan V). On 11 March 2024, the IRDR was admitted for future judgment, and it was determined that all cases filed in São Paulo - Capital remained suspended from its second instance (TRT).

Finally, due to the divergence between the interpretation of the Federal Constitution, an Action for Allegation of Non- Compliance with a Fundamental Precept (ADPF) was also filed, so that the Federal Supreme Court (STF) settles the issue and indicates the correct statute of limitations to be used in the individual cases filed.

On 27 June 2024, an agreement was signed with the indication of a nominal and exhaustive list of 7,299 retirees who, according to the criteria presented by the Bank, are entitled to payment of the amounts related to semi-annual bonuses. The total value of the agreement will be BRL 2.7 billion (EUR 454.3 million); though it will ultimately depend on the individual and voluntary adherence of each beneficiary until 31 July 2024, period that may be extended until 15 August 2024. After the end of the voluntary adherence period, payments will be made in five instalments for living retirees (first installment on 20 October 2024) and a single installment for the heirs of the deceased people (31 October 2024). Considering that it is not possible to estimate the number beneficiaries and the total volume of the obligations that will be involved in the agreement; and that recognition of the obligation is conditional upon the adherence of the beneficiaries within the fixed period, as of 30 June 2024, the recorded provision is based on the estimation of the risk associated to individual claims against the Bank, being subject to the mentioned circumstances the future evolution of the provision and the final cost of the agreement.

•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 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 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'. On 30 June 2024, the provision recorded for the economic plan proceedings amounts to EUR 175.8 million.

•Floor clauses: as a consequence of the acquisition of Banco Popular Español, S.A.U. (Banco Popular), 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 included floor clauses in certain asset-side transactions with customers. In relation to this type of clauses, and after several rulings issued by the Court of Justice of the European Union (CJEU) and the Spanish Supreme Court, and the extrajudicial process established by the Spanish Royal Decree-Law 1/2017, of 20 January, Banco Popular 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. On 30 June 2024, after having processed most of the customer requests, the potential residual loss associated with ongoing court proceedings is estimated at EUR 53.67 million, amount which is fully covered by provisions.

•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 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 rendered five judgements in which it 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. Although four of these five judgments were initially appealed in cassation before the CJEU, in July 2023 one of the appellants withdrew his appeal. Therefore, only the appeals against three judgments are pending before the CJEU and in June 2024, the CJEU upheld the appeal in case C-551/22-P brought by the Commission. Appeals which are still pending in cassation refer to cases C-448/22-P, C-535/22-P and C-541/22-P.

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 15 May, 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 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.

Regarding this judgment, several courts have referred additional preliminary rulings before the CJEU: (i) in December 2022 the Supreme Court requested three preliminary rulings in respect of its applicability to the holders of subordinated obligations, preferred stocks and subordinated bonds of Banco Popular; (ii) in April 2023, the First Instance Court 3 of Santa Coloma de Farners requested three preliminary rulings to the CJEU asking about pre-emptive subscription rights and the compatibility of the principles of proportionality and legal certainty with the bringing of legal actions by former holders of pre-emptive subscription rights and shares against the entity issuing the securities or against the entity succeeding it, which have been stayed by the CJEU until the preliminary rulings raised by the Supreme Court are resolved; and (iii) in November 2023, the Supreme Court requested another two preliminary rulings which supplement the ones requested in December 2022, regarding to a holder of subordinated bonds who filed a claim against Banco Popular before the resolution.

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. On 11 July 2024 the parties were summoned to file their indictment briefs within a 40-day term.

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. In view of the CJEU ruling of 5 May 2022, the Bank requested confirmation of the exclusion of its subsidiary civil liability status in this criminal proceeding. On 26 July 2022, the Court rejected this request stating that it is a matter to be determined at a later procedural time. This decision was confirmed on appeal by the Chamber of the National Court by judgment of 5 October 2022.

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 2022 represented 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 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.

•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. Existing provisions cover the estimated risk of loss.

•Universalpay Entidad de Pago, S.L. (Upay): has filed a lawsuit against Banco Santander, S.A. for breach of the marketing alliance agreement (MAA) and claims payment (EUR 1,050 million). The MAA was originally entered into by Banco Popular and its purpose is the rendering of acquiring services (point of sale payment terminals) for businesses in the Spanish market. The lawsuit was mainly based on the potential breach of clause 6 of the MAA, which establishes certain obligations of exclusivity, non-competition and customer referral. On 16 December 2022, the Court ruled in favour of the Bank and dismissed the plaintiff's claim in its entirety. The decision has been appealed before the Provincial Court of Madrid and the Bank has filed its opposition to Upay's appeal.

Considering the decision at first instance and following the analysis carried out by the Bank's external lawyers, with the best information available to date, it is considered that no provision needs to be registered.

•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 considering that certain contractual clauses in CHF-Indexed loan agreements were abusive. The CJEU 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.

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.

At the same time, the CJEU ruled that, under European law, there is no obstacle to the consumer being able to claim compensation from the bank beyond the return of the installments paid, but at the same time stipulated that such a claim should be evaluated in light of all the circumstances of the case, so that the consumer's possible benefits from the cancellation of the contract do not exceed what is necessary to restore the factual and legal situation in which he would have been without entering into the defective contract and do not constitute an excessive sanction for the entrepreneur (principle of proportionality).

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. The grounds of the above resolution are being awaited.

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.

As of 30 June 2024, Santander Bank Polska S.A. and Santander Consumer Bank S.A. maintained a portfolio of loans affected by the legal risk connected with CHF mortgage for an approximate gross amount of PLN 5,739.4 million (EUR 1,332.2 million). As of 1 January 2022, in accordance with IFRS 9 and based on the new best available information, the accounting methodology was adapted so that 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.

As of the same date, the total value of adjustment to gross carrying amount in accordance with IFRS9 as well as provisions recorded under IAS37, amount to PLN 5,815.2 million (EUR 1,349.8 million) of which PLN 4,565.5 million (EUR 1,059.7 million) corresponds to adjustment to gross carrying amount under IFRS 9 and PLN 1,249.8 million (EUR 290.1 million) to provisions recognized in accordance with IAS 37. The adjustment to gross carrying amount in accordance with IFRS9 in the first 6 months of 2024 amounted to PLN 794.4 million (EUR 184 million), the additional provisions under IAS 37 amounted to PLN 511.8 million (EUR 118.6 million). Other costs related to the dispute amounted to PLN 239.3 million (EUR 55.4 million). These provisions represent the best estimate as at 30 June 2024. Santander Bank Polska and Santander Consumer Bank Poland will continue to monitor and assess appropriateness of those provisions.

In December 2020, the KNF presented a proposal for voluntary settlements between banks and borrowers under which CHF loans would be retrospectively settled as PLN loans bearing an interest rate based on WIBOR plus margin. The KNF continues to support the concept of offering such settlements by banks after the verdict of the CJEU on 15 June 2023. The Bank has prepared settlement proposals which consider both the key elements of conversion of home loans indexed to CHF, as proposed by the KNF Chairman, and the conditions defined internally by the Bank. The proposals are being presented to customers. This is reflected in the model which is currently used to calculate legal risk provisions.

•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.

On 29 June 2022, Santander México, within the framework of the amparo review filed by the Bank, requested the First Collegiate Court in Civil Matters of the Fourth Circuit of Nuevo León the recusal of two of the three Magistrates who rendered against Santander Mexico, which was resolved in favour of Santander Mexico. Plaintiffs requested the recusal of the third Magistrate who ruled with a dissenting vote against the recurso de amparo referred above and this was resolved in favour of Plaintiffs, and consequently the matter was referred to the Second Collegiate Court of the Fourth Circuit based in Nuevo León. The President of this Court considered that the Seventh Civil Chamber of the Superior Court of Justice of Nuevo León had fulfilled the Amparo granted to Mrs. Garza, therefore the Bank presented disconformity “inconformidad”, which was sent for resolution by the Second Collegiate Court of the Fourth Circuit based in Nuevo León. However, on 22 April 2024, the Bank asked the Supreme Court of Justice of the Nation to take up the matter. This has been accepted and consequently, the Supreme Court of Justice will resolve the matter.

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.

•URO Property Holdings, S.A. (before URO Property Holdings, SOCIMI SA): on 16 February 2022, legal proceedings were commenced in the Commercial Court of London against Uro Property Holdings, S.A. (Uro), a subsidiary of Banco Santander, S.A., by BNP Paribas Trust Corporation UK Limited (BNP) in its capacity as trustee on behalf of certain bondholders and beneficiaries of security rights. The litigation concerns certain terms of a financing granted to Uro which was supported by a bond issue in 2015. The claimant seeks a declaration by the Court and a monetary award against Uro, in connection with an additional premium above the nominal value of the financing repayment because of Uro having lost its status as SOCIMI (Sociedad Anónima Cotizada de Inversión Inmobiliaria), such loss causing the prepayment of the bond issue and, in the opinion of the claimant BNP, also the obligation to pay the additional premium by Uro. Uro denies being liable to pay that additional premium and filed its defense statement and a counterclaim against the claimant. The trial hearing has been scheduled for November and December 2024. Furthermore, Uro filed a summary judgement application for BNP's claim to be dismissed before trial. The dismissal of this application by the Commercial Court was confirmed by the Appeal Court. It is estimated that the maximum loss associated with this possible contingency, amounts to approximately EUR 250 million.

•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 September 2020, the Barcelona Court of Appeal, rendered a decision stating that the commencement (dies a quo) for the statute of limitation starts running from the day the consumer fully paid mortgage expenses. The judgment has been appealed to the Supreme Court, which referred a preliminary matter to the ECJ for the establishment of the dies a quo from which the limitation period for the refund action starts running (C-561/21).

On 25 January 2024 the ECJ rendered a judgment (joint cases C‑810/21 and C‑813/21) stating that Directive 93/13 must be fixed on a case-by-case basis by national courts based on the moment when the consumer was aware of the unfair nature of the clause and the legal consequences of such unfair nature. Further, on 25 April 2024, two additional judgments were rendered (cases C-561/21 and C-484/21) in which the ECJ stated that the dies a quo 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 ECJ 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 ECJ 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 ECJ by the First Instance Court No 8 of La Coruña.

In light of the foregoing, there are ongoing issues to be resolved which may have legal consequences. These issues create uncertainties which mean that it is difficult to reliably predict the outcome or the timing of the resolution of the matter. Therefore, the provision recognized includes the best estimate of Group’s liability to 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 June 2024, 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.

Equity [abstract]

Equity

Equity

In the six-month periods ended 30 June 2024 and 2023 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 2024 and 31 December 2023 consisted of EUR 7,747 million and EUR 8,092 million, respectively, represented by 15,494,273,572 and 16,184,146,059 shares of EUR 0.50 of nominal value each, respectively, and all of them of a unique class and series.

On 26 June 2024, there was a capital reduction amounting to EUR 165,652,500 through the redemption of 331,305,000 shares, corresponding to the share buyback program carried out between February and June 2024.

Likewise, on 30 January 2024, there was a capital reduction amounting to EUR 179,283,744 through the redemption of 358,567,487 shares, corresponding to the share buyback program for the year 2023 ended in January 2024.

The operations have not entailed the return of contributions to the shareholders as the Bank is the holder of the redeemed shares.

b)    Share premium

Includes the amount paid by the bank's shareholders in capital issuances in excess of par value.

As a result of the capital reductions described in Note 11.a, during the first semester of 2024, the share premium has been reduced by EUR 2,424 million corresponding to the difference between the purchase value of the shares amortised (EUR 2,769 million) and the nominal value of said shares (EUR 345 million) (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 345 million).

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 six months of 2024, the amount of actuarial losses (net of actuarial gains) has increased by EUR 59 million. The main impacts are:

•Increase of EUR 187 million in the cumulative actuarial losses relating to the Group´s businesses in the UK, mainly due to the behaviour of the asset portfolio and the variation in inflation hypotheses (both short and long term). These effects have been partially offset by the variation in the discount rate (increase from 4.63% to 5.15%).

•Decrease of 63 million in the cumulative actuarial losses relating to the Group's businesses in Brasil, mainly due to the discount rate variation (increase from 8.65% to 9.57% in the main pension plans, from 8.70% to 9.56% in the main medical plan). These effects have been partially offset by the effect of short-term inflation and the behaviour of the asset portfolio.

•Decrease of EUR 43 million in the cumulative actuarial losses relating to the Group's businesses in Mexico, mainly due to the increase in the discount rate (from 9.25% to 10.25%).

•Decrease of EUR 10 million in the cumulative actuarial losses relating to the Group's businesses in Germany, mainly due to the discount rate variation (increase from 3.57% to 3.74%).

The other modification in accumulated actuarial profit or losses is a decrease of EUR 12 million as a result of the evolution of exchange rates and other movements.

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 2024 and 31 December 2023 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:

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 2024 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 appreciation of the Pound Sterling, US dollar and Mexican peso as well as the depreciation of the Brazilian real and Chilean peso (see Note 1.e).

Of this variation, a capital loss of EUR 335 million corresponds to the valuation at the closing exchange rate of goodwill for the first six months of 2024 (see Note 8).

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.

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.

On September 18, 2023, Grupo Santander announced that it is consolidating its retail & commercial and consumer activities across all markets under two new global businesses: Retail & Commercial and Digital Consumer Bank. The changes align these businesses with Santander’s at 30 June 2024, global model in Corporate & Investment Banking, Wealth Management & Insurance and Payments, helping the bank achieve the strategic goals.

The segments are split by business units in which profits are made and by geographic area. 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.

The Group's main level of segmentation, derived from its management model, consolidates the retail, commercial and consumer banking businesses of all markets under the umbrella of two new global business areas:

•Retail & Commercial Banking (Retail): new area that integrates the retail banking business (individuals) and commercial banking (SMEs and corporates), except for business originated in the consumer finance and the cards businesses.

•Digital Consumer Bank (Consumer): comprises all business originated in the consumer finance companies, plus Openbank, Open Digital Services (ODS) and SBNA Consumer.

•Corporate & Investment Banking (CIB): this business, which includes Global Transactional Banking, Global Banking (Global Debt Finance and Corporate Finance) and 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.

•Wealth Management & Insurance (Wealth): includes the asset management business (Santander Asset Management), the corporate unit of Private Banking and International Private Banking in Miami and Switzerland and the insurance business (Santander Insurance).

•Payments: digital payments solutions, providing global technology solutions for our 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).

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 six-month periods ended 30 June 2024 and 2023.

In addition to these operating units, which report by geographic area and businesses, Grupo Santander continues to maintain the area of Corporate Center, 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 six-month periods ended 30 June 2024 and 2023:

a) Valuation techniques for financial assets and liabilities

The following table shows a summary of the fair values, at 30 June 2024 and 31 December 2023, of the financial assets and liabilities indicated below, classified on the basis of the various measurement methods used by Grupo Santander to determine their fair value:

Financial liabilities designated at fair value through profit or loss	—	34,493	34,493	25	40,342	40,367
Hedging derivatives (liabilities)	—	5,535	5,535	—	7,656	7,656
Liabilities under insurance contracts	—	17,592	17,592	—	17,799	17,799

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 six months of 2024 and 2023, 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 2023.

As the end of 30 June 2024, the CVA (Credit Valuation Adjustment) accounted for was EUR 274 million (a decrease of 6.5% compared to 31 December 2023) and adjustments of DVA (Debt Valuation Adjustment) was EUR 265 million (a decrease of 19.7% compared to the end of December 2023). The reduction is mainly due to a decline in the spread curves of the credit markets.

Set forth below are the financial instruments at fair value whose measurement was based on internal models (levels 2 and 3) at 30 June 2024 and 31 December 2023:

(*) 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.

(**)     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 instruments 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 2024 arising from models whose significant inputs are unobservable market data (level 3) amounted to EUR 160 million profit (EUR 178 million in the first six months of 2023).

The table below shows the effect, at 30 June 2024 and 31 December 2023, 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:

30/06/2024
Portfolio/Instrument	Valuation technique	Main unobservable inputs	Range	Weighted average	Impacts (EUR million)
(Level 3)					Unfavourable scenario	Favourable scenario

The risk profile of the home purchase mortgage loan portfolio in Spain remained at a medium-low level, with limited prospects of additional impairment:

•Principal is repaid on all mortgages from the start.

•Early repayment is common so the average life of the transaction is well below that of the contract.

•High quality of collateral concentrated almost exclusively in financing the first home.

•Average affordability rate at the end of June stood at 24%.

•93% of the portfolio has a LTV below 80%, calculated as total risk/latest available house appraisal.

Both preference shares and preferred securities are recorded under the “Financial liabilities at amortized cost – Subordinated Liabilities” caption in the consolidated balance sheet as of 30 June 2024 and 31 December 2023.

Preference shares include the financial instruments issued by the consolidated companies which, although equity for legal purposes, do not meet the requirements for classification as equity in the financial statements. These shares do not carry any voting rights and are non-cumulative.

Preference shares include non-cumulative preferred non-voting shares issued by Santander UK plc.

Preferred securities include non-cumulative preferred non-voting securities issued by Banco Santander, S.A.

For the purposes of payment priority, preferred securities are junior to all general creditors and to subordinated deposits. The payment of dividends on these securities, which have no voting rights, is conditional upon obtaining sufficient distributable profit and upon the limits imposed by Spanish banking regulations on equity.

Preference shares and preferred securities are perpetual securities and there is no obligation that requires the Group to redeem them. All securities have been fully subscribed by third parties outside the Group. In the consolidated balance sheets, these securities are shown net of any temporary transactions relating to liquidity guarantees.

For further information, see Note 23.c. to our consolidated financial statements in Part 1 of our 2023 Form 20-F filed with the SEC on 21 February 2024 and Note 9.b. to our consolidated financial statements in Part 1 of this report.

Introduction, basis of presentation of the interim condensed consolidated financial statements and other information (Policies)

6 Months Ended

Jun. 30, 2024

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 2023 were authorised at the board of directors meeting on 19 February 2024 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 2023 and the consolidated results of its operations, and the consolidated cash flows in 2022. 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 21 February 2024, 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 taking into account the requirements of Circular 3/2018, of June 28, of the Securities and Exchange Commission (CNMV). These interim financial statements will be included in the Half-Yearly Financial Information corresponding to the first half of 2024 that the Group presents in accordance with the aforementioned 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 2023.

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 2023. 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 2023 taking into account the standards and interpretations with effective application date during the first six months of 2024, which are detailed below:

•Amendment to IFRS 16 Lease Liability in a Sale and Leaseback requires a seller-lessee to subsequently measure lease liabilities arising from a leaseback without recognising any amount of the gain or loss that relates to the right of use retained. This new requirement does not prevent a seller-lessee from recognising in profit or loss any gain or loss relating to the partial or full termination of a lease. Applicable, retrospectively, from 1 January 2024.

•Classification of Liabilities, amendments to IAS 1 Presentation of Financial Statements, considering non-current liabilities those in which the entity has the possibility of deferring payment for more than 12 months from the closing date of the reporting period.

Likewise, an additional amendment to IAS 1 on the classification of liabilities with covenants as current or non-current has been approved, specifying that covenants that must be complied with after the reporting date do not affect the classification of liabilities and require additionally their respective breakdowns.

They should be applied retrospectively in accordance with the normal requirements of IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors. Applicable from 1 January 2024.

•IAS 7 Statement of Cash Flows and IFRS 7 Financial Instruments: Additional disclosures are required for companies entering into supplier financing arrangements. The objective of the new disclosures is to provide information on Supplier Finance Arrangements (SFA) that allows investors to evaluate the effects on an entity's liabilities, cash flows and liquidity risk exposure (effective from 1 January 2024).

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 June 2024 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 2024.

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 2023, except for those indicated in these interim financial statements due to the accounting standards and modifications that have come into effect during the first six months of the year 2024.

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:

•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;

•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;

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

•The useful life of the tangible and intangible assets;

•The measurement of goodwill impairment arising on consolidation;

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

•The fair value of certain unquoted assets and liabilities;

•The recoverability of deferred tax assets; and

•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, the levels of inflation and interest rates, as well as the resilience of the labour market being a priority monitoring focus due to the potential uncertainty generated in the Group's estimates.

The Group's management has evaluated in particular the uncertainties caused by the current environment in relation to credit, 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 addition, the Group has applied in the interim financial statements a new theoretical exchange rate for the Argentine peso (1,499 pesos on 30 June 2024). This decision is due to the significant divergence that has been observed between the official exchange rate and other macroeconomic magnitudes, mainly inflation. The new theoretical exchange rate also reflects the implicit exchange rate observed in certain transactions ordered between market participants under the prevailing economic conditions, such as the repatriation of dividends from businesses in Argentina. This matter has not had a material impact in the Group’s interim financial statements.

During the six-month period ended 30 June 2024, there have been no additional significant changes in the estimates made at the end of 2023, other than those indicated in these interim financial statements.

Contingent assets and liabilities

Schedule of basic and diluted earnings per share

Basic earnings per share for the period are calculated by dividing the net profit attributable to Grupo Santander for the first six months adjusted by the after-tax amount relating to the remuneration of contingently convertible preference shares recognised in equity by the weighted average number of ordinary shares outstanding during the period, excluding the average number of treasury shares held in the period.

Accordingly:

	30-06-2024	30-06-2023
Profit attributable to the Parent (EUR million)	6,059	5,241
Remuneration of contingently convertible preferred securities (CCPS) (EUR million)	(309)	(229)

Weighted average number of shares outstanding	15,664,707,190	16,279,041,269
Basic earnings per share (euros)	0.37	0.31
Of which: from discontinued operations (euros)	—	—
from continuing operations (euros)	0.37	0.31

ii. Diluted earnings per share

Diluted earnings per share for the period are calculated by dividing the net profit attributable to Grupo Santander for the first six months adjusted by the after-tax amount relating to the remuneration of contingently convertible preference shares recognised in equity and of perpetual liabilities contingently amortisable in their case by the weighted average number of ordinary shares outstanding during the period, excluding the average number of treasury shares and adjusted for all the dilutive effects inherent to potential ordinary shares (share options, warrants and convertible debt instruments).

Accordingly, diluted earnings per share were determined as follows:

	30-06-2024	30-06-2023
Profit attributable to the Parent (EUR million)	6,059	5,241
Remuneration of contingently convertible preferred securities (CCPS) (EUR million)	(309)	(229)
