Corporate Communications Ciudad Grupo Santander, edificio Arrecife, planta 2 28660 Boadilla del Monte (Madrid) comunicacion@gruposantander.com www.santander.com 1 Santander adds 12 million customers as underlying profit rises 15% to \u20ac7.3 billion in the first half Underlying earnings per share rose 20%1 Net interest income rose 7% and net fee income 9%, driven by more customers and higher activity CET1 ratio stood at 14.0% after completing the acquisition of TSB Madrid, 22 July 2026 – PRESS RELEASE \u2022 Revenue rose 6% to \u20ac30.8 billion, with strong net interest income (NII) and net fee income growth, driven by more customers and increased volumes across global businesses2. \u2022 Loans and customer funds grew 9% and 11%, respectively, in constant euros, driven by higher customer activity and supported by the incorporation of TSB. \u2022 Total costs were down (-2% in constant euros excluding TSB), reflecting efficiency gains from ONE Transformation, which continued to deliver structural operating leverage, supporting revenue growth while reducing cost-to-serve. \u2022 As a result, the efficiency ratio improved to 42.8%, 2.9 percentage points better than a year ago. \u2022 Underlying profit in Q2 reached \u20ac3.8 billion, up 17%. \u2022 Santander completed the acquisition of TSB on 30 April, strengthening its UK franchise with over four million customers, a high-quality deposit base, a low-risk mortgage portfolio and at least \u00a3400 million of expected cost synergies. \u2022 With the buybacks against 2025 results and c.50% of the capital generated from the Poland disposal, as well as the expected c.\u20ac1.8 billion buyback against H1\u201926 results, already approved by the ECB, the bank will have delivered c.\u20ac9 billion towards its commitment to distribute at least \u20ac10 billion through share buybacks for 2025 and 20263. \u2022 Santander is on track to meet its 2026 targets, which exclude the impact of M&A: mid-single-digit revenue growth, costs down, both in constant euros; higher profit (vs. \u20ac14.1 billion in 2025); and a CET1 ratio of 12.8-13%4. Ana Bot\u00edn, Banco Santander executive chair, said: \u201cWe performed strongly in the first half, adding twelve million customers year-on-year. Revenue grew 6% and costs fell, with ONE Transformation driving further improvements in operating leverage and supporting record profits. The successful completion of the TSB acquisition in the UK marks another important milestone in the execution of our strategy. It strengthens our position in one of our core markets, adding scale, high-quality deposits and a low-risk mortgage portfolio, while creating significant opportunities to improve our customer offering and profitability once the integration is complete. In 2026, including the expected buyback against our first half results which has been approved by the ECB3, we are on track to execute a total of \u20ac6.9 billion in share buybacks, equivalent to c.114 basis points of CET1, while continuing to invest in profitable growth opportunities across our footprint. Our business, geographic and balance sheet diversification, together with a team that has demonstrated disciplined execution and prudence in risk management, remain key strengths amid heightened geopolitical uncertainty. We are confident that our strategy will continue to drive profitable growth and sustainable value creation, and once again reaffirm all our 2026 and medium-term targets.\u201d <\/p>\n

Summary of statutory figures at the end of this press release. Underlying business performance All variations are year-on-year unless otherwise stated. Banco Santander reported a record underlying profit of \u20ac7,328 million in the first half of 2026, up 15%, driven by strong customer activity and the continued execution of ONE Transformation, that is resulting in lower costs. Attributable profit reached \u20ac8,973 million, up 31%, including a \u20ac1.9 billion net capital gain following the completion of the disposal of Santander Bank Polska in January, partially offset by \u20ac250 million of restructuring costs related to the integration of TSB. Underlying results exclude these non-recurring items, providing a consistent view of operating performance. Santander continued to expand its customer base, adding 12 million customers over the last twelve months to reach 182 million in total, driven by strong commercial momentum across all businesses, together with the addition of more than four million TSB customers following the acquisition, which was completed on 30 April. The bank continued to improve profitability and create value for shareholders, achieving an underlying return on tangible equity (RoTE) of 15.6% (+0.7 percentage points), with underlying earnings per share (EPS) up 20%. Tangible net asset value (TNAV) plus cash dividend per share increased 19%, reflecting sustained value creation driven by higher profitability and disciplined capital allocation. Business volumes remained strong, with loans increasing 9% and customer funds (deposits + mutual funds) 11% in constant euros, supported by solid commercial momentum across global businesses and the incorporation of TSB. Excluding TSB, loans increased 5% and customer funds 7% (deposits +5%) in constant euros. Loan growth was driven by mortgages in Retail, auto lending in Openbank and double-digit loan growth in CIB. Total revenue increased 6% to \u20ac30,847 million, supported by net interest income of \u20ac22,711 million (+7%) and net fee income of \u20ac6,851 million (+9%), reflecting higher customer activity, deeper customer relationships and business volume growth across all global businesses. More than 95% of group revenue continues to be linked to customer activity, providing resilience in the current interest rate environment. <\/p>\n

Corporate Communications Ciudad Grupo Santander, edificio Arrecife, planta 2 28660 Boadilla del Monte (Madrid) comunicacion@gruposantander.com www.santander.com 3 Total costs were down (-2% in constant euros excluding TSB), reflecting continued efficiency gains from ONE Transformation, which more than offset inflationary pressures and investments to support business growth. As a result, net operating income increased 12% to \u20ac17,636 million, while the efficiency ratio improved by 2.9 percentage points to 42.8%, supported by structurally lower costs and higher revenue. The group also continued to accelerate the deployment of AI across its businesses, generating \u20ac84 million of business value (higher revenue, lower costs and lower loan-loss provisions) in the first half through improved customer service, higher productivity and commercial growth. Loan-loss provisions increased 9%, mainly reflecting broader market trends in Argentina; excluding this impact, provisions were broadly stable. Credit quality remained solid, with cost of risk at 1.15%, supported by prudent risk management, diversified exposure and historically low unemployment levels across most of the bank’s markets. The non-performing loan ratio improved to 2.93% versus the previous quarter (-7 basis points), remaining at historically low levels, with a coverage ratio of 64%. The CET1 capital ratio reached 14.0%. Excluding the -55 basis point impact from the TSB acquisition completed on 30 April, the group generated 20 basis points of capital in the quarter through strong organic capital generation. Taking into account the expected impact of the Webster acquisition, Santander remains well positioned to meet its year-end CET1 target between 12.8% and 13%, at the high end of its 12-13% operating range. Santander continued to deliver attractive shareholder returns, with TNAV plus cash dividend per share up 19%. During the first half, the bank completed the payment of the 2025 cash dividend of 24 euro cents per share, up 14% year-on-year, and continued executing the \u20ac5.0 billion share buyback programme announced in February, including the additional distribution linked to the Poland disposal. Including the share buyback programme currently underway and the expected c.\u20ac1.8 billion share buyback programme against H1 2026 earnings, Santander will have delivered c.\u20ac9 billion towards its plan to distribute at least \u20ac10 billion through share buybacks for 2025 and 20263. The implementation of the programme against H1 2026 results, which has already been approved by the ECB, is subject to the corresponding corporate approvals and its terms will be communicated in due course following approval. Outlook Santander reiterates all its 2026 targets, which exclude the impact of M&A in 2025 and 2026. These targets include mid- single-digit revenue growth and lower costs in constant euros, higher profit than the \u20ac14.1 billion reported in 2025, and a CET1 ratio between 12.8% and 13%. Revenue growth is expected to continue to be supported by customer activity, with net fee income growing faster than net interest income, while cost discipline and ONE Transformation will continue to drive positive operating leverage. Santander also reiterates its three-year plan as outlined at its Investor Day last February: by 2028, the group targets a RoTE above 20%, profit above \u20ac20 billion and more than 210 million customers4, supported by scale, network effects and continued improvements in productivity and capital allocation. Note: YoY changes in constant euros. Targets market dependent. Based on macro assumptions aligned with international economic institutions. Excluding Poland, TSB and Webster in 2025-26, as defined during the Investor Day in February 2026. TNAVps + Cash DPS includes the \u20ac11.50 cent cash dividend per share paid in November 2025 and the \u20ac12.50 cent cash dividend per share paid in May 2026, all forming part of our shareholder ordinary remuneration policy against 2025 results. <\/p>\n

(\u201cSantander\u201d) cautions that this document may contain financial information prepared according to International Financial Reporting Standards (IFRS) and taken from our consolidated financial statements, as well as alternative performance measures (APMs) as defined in the Guidelines on Alternative Performance Measures issued by the European Securities and Markets Authority (ESMA) on 5 October 2015, and other non-IFRS measures. The APMs and non-IFRS measures were calculated with information from Grupo Santander; however, they are neither defined or detailed in the applicable financial reporting framework nor audited or reviewed by our auditors. We use the APMs and non-IFRS measures when planning, monitoring and evaluating our performance. We consider them to be useful metrics for our management and investors to compare operating performance between accounting periods. Nonetheless, the APMs and non-IFRS measures are supplemental information; their purpose is not to substitute the IFRS measures. Furthermore, other companies, including some in our industry, may calculate or use APMs and non-IFRS measures differently, thus making them less useful for comparison purposes. APMs using environmental, social and governance labels have not been calculated in accordance with the Taxonomy Regulation or with the indicators for principal adverse impact in SFDR. For more details on APMs and non-IFRS measures, please see the 2025 Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission (the SEC) on 27 February 2026 (https:\/\/www.santander.com\/content\/dam\/santander-com\/es\/documentos\/informacion-sobre- resultados-semestrales-y-anuales-suministrada-a-la-sec\/2026\/sec-2025-annual-20-f-2025-disponible-solo-en-ingles-es.pdf), except with respect to the information and the audited financial statements included therein and superseded by the information and the audited financial statements included in our Report on Form 6-K furnished to the SEC on 1 April 2026 relating to certain recast financial information as a result of certain changes to the presentation of the Group\u2019s financial information (https:\/\/www.santander.com\/content\/dam\/santander- com\/en\/documentos\/informacion-sobre-resultados-semestrales-y-anuales-suministrada-a-la-sec\/2026\/sec-recast-of-certain-financial- information-and-related-disclosure-for-the-three-years-ended-31-december-2025-en.pdf), as well as the section \u201cAlternative performance measures\u201d of our second quarter financial report, which was published on 22 July 2026 (https:\/\/www.santander.com\/en\/shareholders-and- investors\/financial-and-economic-information#quarterly-results) Forward-looking statements Santander hereby warns that this document may contain ‘forward-looking statements’, as defined by the US Private Securities Litigation Reform Act of 1995.
