Section 1: Key information Summary of results Solid financial performance with a ROAE1 of 25.7% in 1Q252, the fourth consecutive quarter with a ROAE of over 20%. As of March 31, 2025, the bank's net income attributable to shareholders totaled $278 billion ($1.47 per share and $0.62 per ADR), representing a 131.0% YoY3 increase and an ROAE of 25.7%, compared to an ROAE of 11.2% in 1Q24. The increase in results is explained by an increase in the bank's main revenue lines. Operating income increased 33.2% YoY, driven by a better net interest and readjustment income. Compared to the previous quarter, 4Q24, the bank's net income attributable to shareholders increased by 0.5%. The UF variation in 1Q25 was slightly lower than in 4Q24, which reduced QoQ4 readjustment gains. This was offset by higher fees and results from financial transactions and improved expense control. This resulted in a ROAE of 25.7% in 1Q25, marking the fourth consecutive quarter with ROAEs above 20%. Dividend payment of Ch$3.19 per share with a dividend yield of 5.4%. A solid CET15 ratio of 10.7%. At our Ordinary Shareholders' Meeting on April 22, 2025, the distribution of 70% of our 2024 earnings, amounting to $857,623 million, was approved. These earnings represent a dividend of $3.18571574 Chilean pesos per share, for a total of $600,336 million. Likewise, it was approved that the remaining 30% be partially allocated to increasing the Accumulated Earnings from previous years by the amount necessary to cover the payment of the next three interest coupons on the fixed-term bonds for $29.993 billion and to increase the Bank's Reserves and Other Retained Earnings by $227.294 billion. Our CET1 ratio remains at a solid 10.7% at the end of March 2025, with the overall Basel III ratio reaching 16.9%. The Bank's capital includes a dividend payment provision of 70% of 2024 earnings and a 60% provision of 2025 earnings to date. 4 1Annualized net income attributable to bank owners divided by the average equity attributable to equity holders.2The first quarter of 20253Year on year4 Quarter on quarter5 Common Equity Tier 1 under Chilean regulation.

Strong recovery of NIM6, reaching 4.1% in 1Q25 Net interest and readjustment income (NII) accumulated as of March 31, 2025, increased 41.7% compared to the same period in 2024. This increase in NII was due to higher net interest income due to the impact of a lower monetary policy rate on our funding cost, which fell from 5.3% to 3.9% in 3M25. The increase is also explained by higher readjustment income, resulting from a greater variation in the UF during the quarter compared to the same quarter last year. Compared to 4Q24, net interest and readjustment income decreased slightly due to lower inflation in 1Q25 compared to the previous quarter. Given the above, the NIM increased from 2.7% in 1Q24 to 4.2% in 4Q24 to 4.1% in 1Q25. Gravity: Migration of our systems to the cloud. Best-in-class efficiency of 35.0% in 1Q25. In 1Q25, the Bank celebrated the major milestone of the Gravity project, the migration from the Mainframe to the Cloud. In January, we transitioned processing to our new Cloud, which resulted in higher technology expenses related to the change and write-downs and impairments related to legacy systems. The Bank's efficiency ratio7 reached 35.0% as of March 31, 2025, better than the 47.4% of the same period in the previous year. Total operating expenses (which include other expenses) decreased 1.7% in 3M25 compared to 3M24, driven by lower other operating expenses related to the restructuring of our branch network and the transformation to Work/Café. The customer base continues to expand, with total customers increasing by 9.4% YoY and digital customers increasing by 6.6% YoY. Our strategy of strengthening our digital products has led to continued growth in our customer base, reaching approximately 4.3 million customers, of which nearly 2.3 million are digital customers (88% of our active customers). The Bank's market share in checking accounts remains strong at 22.5% through February 2025, driven by increased customer demand for US dollar checking accounts, as customers can open these types of accounts digitally through our platform in a few easy steps. This also demonstrates the success of Getnet's strategy to encourage cross-selling of other products such as the Cuenta Pyme Life. 5 6NIM: Net interest margin.

Net commissions increased by 16.8% in 3M25, reaching recurrence levels8 of 61.8%. Net commissions increased 16.8% in the three months ended March 31, 2025, compared to the same period in 2024, driven by increased customer numbers and greater product usage. As a result, the recurrence ratio (total net commissions divided by structural support expenses) increased from 57.8% as of March 2024 to 61.8% as of March 2025, demonstrating that more than half of the Bank's expenses are financed by commissions generated by our customers.

Macroeconomic Environment All of our operations and the majority of our customers are located in Chile. Consequently, our financial condition and results of operations depend substantially on prevailing economic conditions in the country. Economic activity during the first months of the year has been broadly in line with market expectations, reflecting increased activity in the trade sector, offset by a decline in activity in the mining sector. The February 2025 Imacec index (IMEC) fell -0.1% year-on-year, slightly below market expectations. This result was affected by one fewer day than in February 2024, a leap year, and by the power outage that affected much of the country. For 2025, we project GDP growth of 2.1%, driven by a stronger recovery in domestic demand, particularly investment concentrated in mining and energy sector projects. The trade war represents a significant threat to Chile, given its open economy, highly integrated into international trade. Slower global growth will affect demand for our exports, especially from key trading partners. Added to this is the negative impact on financial markets and deteriorating business and consumer confidence, factors that eventually translate into a slowdown in consumption and, especially, investment. This occurs in a context where demand for credit remains weak. The labor market is beginning to gain momentum. The rebound in formal employment is notable; its dynamism, along with sustained wage increases, creates a more favorable environment for domestic consumption. The unemployment rate for the three-month period ending in February stood at 8.4%. CPI (12 months) m ar -2 1 ju n- 21 se pt -2 1 di c- 21 M ar -2 2 ju n- 22 se pt -2 2 di c- 22 M ar -2 3 Ju ne 2 3 S ep t-2 3 D ec -2 3 M ar -2 4 Ju ne 2 4 S ep t-2 4 D ec -2 4 M ar -2 5 0.0 2.0 4.0 6.0 8.0 10.0 12.0 14.0 16.0 Inflation is starting the year in line with expectations. The March CPI rose 0.5% m/m, bringing the annual rate to 4.9%. The inflationary convergence process will continue, and the external outlook allows for a more rapid slowdown, reaching 3.7% for the full year. However, the moderation in activity is expected to lead to inflation of 2.9% at the close of 2026, with risks skewed to the downside. The UF variation in 1Q25 decreased slightly compared to the previous quarter (1.2% in 1Q25 vs. 1.3% in 4Q24). We expect the UF variation to reach 3.6% by 2025 (vs. 4.4% in 2024), in line with inflation levels. During the first months of 2025, the exchange rate has been highly volatile. While the peso appreciated against the dollar until mid-March, it depreciated significantly again during the second half of March due to the Fed's announcements and the Trump administration's tariff policies. While we are facing a scenario of uncertainty in this regard, our expectations are for an exchange rate of around 970 by the end of the year. 10

At its last meeting in 2024, the Central Bank cut the rate by 25 basis points to 5.0%, which was maintained at its January meeting. The recent developments surrounding the US tariffs would weaken global growth, putting a certain brake on activity and leading to a more rapid decline in inflation, which would require a more accommodative policy to avoid costly overadjustment. Given this, we estimate that the Central Bank Board would have the room to make the two cuts suggested in the latest Monetary Policy Report, but still close to the lower end of the rate corridor. In particular, we believe it is possible to bring forward the cut process to June, adding an additional rate cut during the final quarter, ending with a rate of 4.50% by the end of 2025.

Pension Reform On January 29, 2025, Congress approved the new pension reform. The main changes are: • 7% increase in pension contributions, payable by the employer, with gradual implementation over nine years. • Six percent will go to direct and deferred individual capitalization, and 1% to the new Social Security, which will also include the current 1.5% allocated to Disability and Survivors' Insurance. These funds will allow equal pensions for men and women in similar circumstances at retirement. • Tendering of 10% of the membership pool every two years, in order to increase competition. • Space and incentives for the entry of new pension fund managers. • Increase in the Guaranteed Universal Pension (PGU) to $250,000 pesos for 90% of the most vulnerable population. Tax reform The government is implementing a fiscal pact, seeking to modernize the current tax system, prioritize spending, increase transparency in state services, and achieve fiscal oversight. As part of this, they hope to encourage investment, productivity, and formalize the economy while closing opportunities for tax avoidance. During 2024, Congress approved the Tax Obligations Compliance Bill, which seeks to raise 1.5% of Gross Domestic Product (GDP) by reducing tax payment gaps due to tax avoidance, evasion, and/or involuntary underreporting. Also in the context of the fiscal pact, the government worked on a reform that sought to modify the income tax, cutting the corporate rate from 27% to 24%. However, in April 2025, news of global tariffs led to a change in priorities, and the Minister of Finance announced the indefinite postponement of this income tax reform. Pillar 2 – Basel III Implementation In the context of the implementation of Basel III, specifically in the case of Pillar 2, the CMF is evaluating and quantifying the material non-traditional risks to which each bank is exposed to determine the application of regulatory capital charges under Pillar 2. The risks covered under Pillar 1, which are considered traditional risks, are: credit, market, and operational risks. The non-traditional risks, which Pillar II seeks to cover (and which depend on each bank's business model), are: market risks related to the banking book; credit concentration; reputational; strategic; cybersecurity; geopolitical; climate, among others. On October 11, 2024, the CMF published a consultation version of the Pillar 2 capital requirements regulations, to which banks submitted their comments, and the CMF has not yet published its final version. On January 17, 2025, the CMF applies for the second time the current regulations on additional capital requirements according to Pillar 2, where the Council resolved to apply said requirements to the same institutions as the previous year, these are Banco Bice, Banco BTG Pactual Chile, Banco Consorcio, Banco de Chile, Banco del Estado de Chile, Banco Internacional, Banco Security, HSBC Bank (Chile), Scotiabank Chile. Finally, on April 11, the CMF (Federal Commission for the Protection of Financial Institutions) resolved to establish a requirement of 25 basis points of total capital for Banco Santander Chile, which will be applied progressively, with an initial tranche of 50% to be realized before June 30, 2025. The reported adjustment responds to technical analysis associated with metrics reviewed and updated by the bank, in accordance with its 12

internal validation processes and in coordination with the CMF. Banco Santander Chile already contemplated capital allowances above the regulatory minimums, so compliance with this requirement does not imply the need for new capital contributions. The charge will be absorbed with resources already available within the bank's effective equity. This update has no impact on the bank's financial position, solvency, or results, nor did it affect the dividend proposal for the Shareholders' Meeting held on April 22, 2025. It also does not affect the terms offered to clients or the strategic projections for shareholders. Interchange fees In February 2023, the Interchange Rate Capping Committee proposed new rate caps. These were approved at the end of April 2023 and will be implemented gradually. Card type Current rate Primera baja (Oct-23) Segunda baja (oct-24) (Suspendida) Debit 0.6% 0.5% 0.35% Credit 1.48% 1.14% 0.80% Prepaid 1.04% 0.94% 0.80% To assess the effects of the gradual implementation of the exchange rate capping process, the Committee agreed to conduct an impact study on: (i) the application of the preliminary rates; (ii) the first reduction established in this resolution; (iii) the evaluation of the potential effects, or those reasonably foreseeable, of the second reduction; and (iv) all market aspects relevant to the Committee's fulfillment of its objectives established in the aforementioned law. This report has not yet been published. On September 30, 2024, the Committee indicated that it had initiated a review process for the limits on interchange rates, and therefore would maintain the limits in effect to date; that is, the reduction scheduled for October 2024 was suspended. Given the timing of the process, we estimate that the committee could define the interchange fees towards the end of the year. Fraud Law In early April, improvements were approved to Fraud Law No. 20,009 to combat the recent increase in bank transaction fraud (better known as self-fraud) and other crimes associated with opportunistic behavior, which have severely impacted financial institutions. Certain aspects have been modified, such as: i) reimbursement deadlines for unknown transactions; ii) the requirement for a sworn statement from the user and a criminal complaint to be filed in order to enforce a fraud claim; iii) a new suspension procedure has been created, regardless of the amount claimed, when the issuer has sufficient evidence of fraudulent misconduct or gross negligence on the part of the user. The procedure must then be submitted to the local police court requesting authorization to maintain the suspension, among other measures. Consolidated debt In early June 2024, the Consolidated Debt Law was approved, creating a free, public Consolidated Debt Registry (Redec), which will be administered by the Financial Market Commission (CMF). The new law establishes that new institutions that did not previously do so will be required to report outstanding loans granted to individuals to the CMF. These include mortgage loan providers; family allowance compensation funds; credit card issuers 13

(supervised by the CMF); securitization companies; credit advisory entities regulated by the Fintec Law; and any other entity supervised by the CMF, as determined by the CMF through General Regulation. Furthermore, it is made clear that the individual is the owner of their data and is guaranteed the right to protection thereof, under the supervision of the CMF. This establishes their rights to update, rectify, and delete information, along with defining severe penalties for negligent or malicious access to or use of Redec information. To access registry information, reporters must have prior consent, which will be granted solely for the purpose of assessing their commercial or credit risk for a specific transaction and for a limited period of time. Fintec and Open Finance Law In early July, the Financial Market Commission (CMF) published the regulations governing the Open Finance System (SFA) or open finance of the Fintec Law, which will come into effect in July 2026. The regulation establishes that institutions currently regulated in the financial system - such as banks, payment card issuers, insurance companies, fund managers, savings and credit cooperatives supervised by the CMF - must comply with the SFA in order to provide the information that the user decides to share with other participating institutions, upon prior consent. In addition, the CMF established standards for institutions that voluntarily decide to register with the SFA and thus offer financial services to users. The implementation period for the SFA will be gradual, depending on the role each participant plays within this scheme. The first phase, as defined, has a 24-month deadline for entry into force, a period that will be used for the adaptations required for implementation by each participant. In addition, during this period, technical manuals with specifications will be developed. After this period, the standard contains an implementation schedule that begins with the progressive delivery of information that banks and payment card issuers must share within the following 18 months. Then, within the following 18 months, the obligation will begin for savings and credit cooperatives supervised by the CMF, insurance companies, fund administrators, and compensation funds, among others. Therefore, full implementation of the standard is estimated to take five years. Dividend Subsidy Law In January 2025, the Dividend Subsidy bill was introduced. It proposes reducing mortgage interest rates for new home purchases, seeking to facilitate access to homeownership and reactivate the real estate market. The project's features include a mortgage interest rate subsidy of up to 60 basis points. It also includes a state guarantee from the Special Guarantee Fund (FOGAES) that covers up to 60% of the home's value, which could further reduce the total interest rate by up to 100 basis points. The project seeks to provide 50,000 subsidies, of which 10% will be allocated to homes worth up to 3,000 UF and the remaining percentage to new homes worth up to 4,000 UF. Regulation and supervision In Chile, only banks may maintain current accounts for their customers, conduct foreign trade transactions, and, along with regulated non-bank financial institutions such as cooperatives, accept term deposits. The primary authorities regulating financial institutions in Chile are the Financial Market Commission (CMF) and the Central 14

Bank. Chilean banks are subject primarily to the General Banking Law and, secondarily, to the extent not inconsistent with this statute, to the provisions of the Chilean Companies Law governing corporations, except for certain provisions that are expressly excluded.

Seventy-nine percent of individual loans go to upper-middle-income individuals; however, the Bank has an innovative strategy for mass income. Within the retail segment, there are individuals, businesses, and Santander Consumer (auto financing), as detailed below. • Individuals: Santander Life continues to be a leading contributor to new customer growth, offering a digital onboarding process for opening a checking account. Santander Life customers are rapidly monetizing while achieving a high Net Promoter Score (NPS) for the onboarding process. Furthermore, continuing our commitment to financial inclusion, we launched "Más Lucas," the first profitable checking and savings account, 100% digital for the mass market. This product charges no maintenance or transaction fees; the checking account pays a fixed monthly rate based on the average balance maintained in the account. • Santander Consumer (auto financing): This business has been very proactive in increasing its partnerships with various automakers.. 19

• Companies: We continue to open digital checking accounts for these clients, which, combined with Getnet's service offering, completes the range of solutions for their businesses. Results: Retail banking's net contribution decreased 42.2% YoY. Margin increased 4.6% YoY due to a better mix, driven by growth in consumer loans. Fees in this segment increased sharply by 17.1% YoY, driven by card fees due to increased usage and a growing customer base, which also impacted the growth in current account fees. Provisions increased 75.8% YoY, mainly due to the reclassification of additional provisions to the consumer portfolio due to the change in the provisioning model established by the regulator, which came into effect in January 2025. Asset quality has also worsened due to lower economic growth and a weaker labor market. Operating costs increased 10.6% YoY, mainly due to the digital transformation and the migration of our systems to the cloud, as part of Project Gravity, which reached an important milestone in January 2025 when the bank began operating in the cloud. Compared to 4Q24, retail banking's net contribution decreased 40.2% QoQ, primarily impacted by the one-time effects of provisions and operating expenses in the quarter, as explained above. Margin remained stable in the quarter, and fees increased 1.5% in the quarter following higher spending in 4Q24 related to the credit card loyalty program. Wealth Management & Insurance: This unit aims to unify the investment offering, enabling greater consistency across all segments and better communication of products and services. Its focus is on generating a specialized investment strategy for each segment, establishing unique digital development and communication plans. Its core businesses are insurance and the distribution of investment instruments for the Retail and Private Banking segments.

Business activity: The loan portfolio in this segment increased 11.4% YoY due to increased demand for commercial and mortgage loans and credit cards. Compared to 4Q24, growth was driven by commercial and mortgage loans, while credit card loans normalized after seasonality at the end of the year. Deposits increased 43.7% YoY, primarily due to term deposits in Chilean pesos and demand funds. Growth in the quarter was also driven by increased savings from our customers. Results: Wealth Management & Insurance's net contribution increased 0.7% YoY, driven by higher margins due to portfolio growth and higher fees generated by mutual funds and insurance. This was offset by higher provisions due to portfolio growth, and higher salary-related and technology-related expenses. In the quarter, Wealth Management & Insurance's net contribution was a gain of $9,196 million, a 79.2% QoQ increase, primarily due to a higher margin resulting from a better spread on cards and higher fees related to insurance and mutual funds. This was partially offset by higher provisions related to portfolio growth.

Deposits increased 1.9% since March 31, 2024, and 0.1% QoQ, due to higher balances at year-end. The main strategic objective of this segment is to focus on total customer profitability, across lending and non-lending activities. 21

Results: The Middle-market's net contribution increased 9.0% YoY, primarily due to a higher margin from portfolio growth and higher fees and financial transactions generated by our commercial clients. This was offset by an increase in provisions. During 2024, there was greater risk in sectors such as agriculture, which were affected by the intense rains and flooding caused by the "El Niño" phenomenon, which primarily affected Chile's central regions, where crops are abundant. In the quarter, the middle-market's net contribution increased 30.9% QoQ, primarily due to a decrease in provisioning expenses after an increase in 4Q24 and also due to increased margin and fees in the quarter in line with increased customer activity.

Loans in this segment decreased by 5.3% QoQ due to exchange rate effects in the quarter. Deposits decreased by 21.0% since March 31, 2024, and by 16.3% QoQ, explained by an increase in our customers' liquidity in this segment at the end of the year, which drained off in the first weeks of the year. Results: Total revenues for this segment decreased 1.3% YoY. Net interest and readjustment income decreased 17.7% YoY due to lower loan volumes. This was partially offset by a provision release in the quarter related to portfolio 22

contraction and a decrease in riskier loans. Expenses increased 9.2% YoY due to higher variable salaries and technology expenses. In the quarter, CIB's net contribution was a gain of $66.26 billion, a 24.7% QoQ increase due to lower margin revenues explained by the portfolio contraction in the quarter and lower fees generated by financial advisory services. This was offset by a gain in financial transactions compared to a loss in 4Q24, and a provision release in the quarter. Expenses also decreased due to lower technology and remuneration expenses.

It is important to note that the last FCIC payment was made on July 1, 2024. Additionally, the new provisioning model for the consumer portfolio went into effect in January 2025. With this, the Bank reallocated voluntary provisions from corporate activities to Retail Banking. In the quarter, profit after tax was $65.292 billion, primarily due to the release of the aforementioned voluntary provisions in the quarter and partially offset by a higher margin loss due to a lower variation in UF in the quarter. 23

Section 4: Balance sheet and results Balance sheet Loan growth led by retail banking Total loans decreased 0.5% QoQ and 0.4% compared to March 31, 2024. The consumer portfolio associated with our Santander Consumer and Credit Card businesses grew significantly over the last 12 months. Mortgage loans grew YoY, albeit at low levels and below inflation, while the slower economic growth, along with exchange rate effects, translated into contractions in the commercial portfolio.

Total gross loans from provisions at amortized cost. Commercial loans decreased by 3.8% since March 31, 2024, and by 0.9% QoQ. Approximately 57% of our portfolio is indexed to the UF, mostly mortgage loans and approximately 34% of commercial loans. Approximately 24% of commercial loans (from the Middle-market and CIB segments) are denominated in foreign currencies, primarily in US dollars, so US$-denominated commercial loans have shown volatility in their peso value in recent quarters. In the first quarter of 2025, the Chilean peso recovered, appreciating 4.0% QoQ and 2.8% since March 2024, explaining the contraction in this portfolio due to the US$ depreciation of 0.9% and 0.6%, respectively. In general, commercial loans have been impacted by lower demand related to the macroeconomic environment. Also, as part of the business, our Corporate & Investment Bank uses a generate-to-distribute model, which has offset the growth of this product compared to March 2024. Furthermore, during the second quarter of 2024, the exclusion of Bansa S.A. from the Bank's consolidation (approximately 0.5% of the total portfolio) was determined. Mortgage loans are growing below inflation, reaching 1.6% growth since March 31, 2024, and declining 0.1% QoQ. In the recent periods, new mortgage loan originations have declined due to continued weak demand, affected by higher house price inflation and interest rates in recent years. The Bank also seeks to maintain its strategy of higher-yield loans. 24

Consumer loans decreased 0.9% QoQ and increased 4.0% since March 31, 2024. Between the end of 2019 and 2021, credit card loans decreased 7.0% as customers reduced major purchases, such as travel and hotels. At the same time, many customers paid off credit card debt with the liquidity obtained from government transfers and pension withdrawals.

After a seasonal increase in December 2024, credit card debt decreased slightly in the quarter, while increasing by 10.8% compared to March 2024. Additionally, within our consumer loans is our auto financing business, Santander Consumer, which has shown positive trends with a 13.6% increase since March 2024 and a 2.1% increase in the quarter.

Customers included in each business segment are constantly reviewed and reclassified if a customer does not meet the segment's criteria. Therefore, variations in business volumes and results may reflect business trends and the effects of customer migration. Retail banking loans grew 1.4% since March 31, 2024, driven by growth in consumer loans (credit cards and auto financing) and mortgages. In 1Q25, retail banking loans contracted 2.2% QoQ due to lower demand for mortgages, credit cards, and other consumer loans. Wealth Management & Insurance loans increased 11.4% since March 31, 2024, and 2.3% QoQ, driven by increased demand for commercial and mortgage loans and, more recently, credit cards during the quarter. 25

The Middle-market segment's loan portfolio increased by 3.7% since March 31, 2024, and by 5.3% QoQ, mainly due to the migration of corporate clients that were classified as SMEs and therefore part of the Retail Banking sector to the Middle-market segment thanks to the growth of their business in recent periods. CIB loans decreased 34.5% since March 31, 2024, partly due to the use of the generate-to-distribute model, combined with slower economic activity. In 1Q25, loans in this segment decreased 5.3% QoQ due to lower demand from our clients at the beginning of the year.

On April 1 and July 1, 2024, we made payments of Ch$3.3 trillion and Ch$2.8 trillion, respectively, for the FCIC using the Central Bank's liquidity deposit program, accounting for the contraction in the available-for-sale and - to-maturity portfolio during 2024. In June 2024, the Ministry of Finance carried out an early redemption or exchange exercise for a list of existing bonds. This exercise was intended to manage the maturity of Chilean government debt in the coming years, offering new bonds to support liquidity and retiring non-benchmark bonds. During June 2024, the Bank participated in this bidding process, for a total nominal value of Ch$4.32 billion. At the close of March 2025, the HTM instruments have a fair market value of Ch$4,761,345 million. 26

Calculated in accordance with Chilean regulations. The Central Bank's last rate hike was in October 2022, when the monetary policy rate (MPR) reached 11.25%, closing the cycle of increases. This increase and its prolonged maintenance directly impacted our financing costs. The rate cut cycle began at the end of July 2023, and after five successive cuts, the MPR closed 2023 at 8.3%. In 2024, the Central Bank continued to cut the rate, reaching 5.0% in December. The Bank's total deposits increased 0.6% since March 31, 2024, driven by a 2.4% increase in time deposits and offset by a 1.5% decrease in demand deposits. In the quarter, total deposits decreased 2.4%, with demand deposits falling 6.7%, explained by the seasonality of deposits at year-end, particularly among our corporate clients. This was partially offset by an increase in time deposits in the quarter. Our customers' investments through mutual funds brokered by the Bank grew in the quarter, reaching an increase of 2.1% QoQ and 20.1% since March 31, 2024, given our clients' preference for mutual funds in this scenario of falling rates. The reduction in the Central Bank's lines of credit is due to the full payment of the FCIC (a facility granted by the Central Bank during the pandemic) by July 2024. Bonds decreased 4.7% in the quarter and 5.4% since March 31, 2024. In January 2025, the Bank made a payment on the maturity of a 144A bond corresponding to USD 704 million. During 2025, the Bank placed bonds for UF 6,385,000, taking advantage of attractive opportunities in various fixed-income markets nationwide. The contraction in this item is in line with lower growth in our long-term loans (mortgage and commercial). The Bank's Liquidity Coverage Ratio (LCR), which measures the percentage of liquid assets as a percentage of net cash outflows, as of March 31, 2025, was 192.9%, well above the minimum. As of the same date, the Bank's Net Stable Funding Ratio (NSFR), which measures the percentage of illiquid assets funded through stable funding sources, reached 104.3%, also above the current legal minimum for this ratio. 27

This represents a dividend per share of Ch$3.19 and a dividend yield of 5.4%. As of March 2025, the Bank has established a dividend provision of 60% of profits in 2025. This was in line with the Board's view of the Bank's earnings expectations for the year. With this, the capital ratios reflect a dividend provision in line with historical dividend payments. Total equity reached $4,507,401 million as of March 31, 2025, an increase of 2.5% QoQ primarily due to the increase in profit for the period. Compared to March 31, 2024, total equity increased 5.1% due to higher earnings in the quarter, offset by a higher dividend payment provision of 70% of 2024 earnings and 60% of 2025 earnings, as previously mentioned. 28

Leverage: Core capital / Total regulatory assets, as calculated by the CMF. Our CET1 ratio remained strong at 10.7% and the overall Basel III ratio reached 16.9% at the end of March 2025. Risk-weighted assets (RWA) increased 1.2% from March 31, 2024, and 0.5% QoQ, mainly due to higher market risk-weighted assets from our CIB clients. In April 2025, the CMF informed the Bank of a Pillar 2 charge of 25bp. Fifty percent of this charge should be in place by June 2025, and the remainder by June 2026, with 56.3% comprised of CET1. With this, our minimum CET1 requirement at the end of 2025 is 9.07%. The Bank's ROAE was 25.7% in 1Q25 compared to 26.0% in 4Q24, due to slightly lower inflation in the quarter. The sharp increase in ROAE, from 11.2% in 1Q24, is explained by improvements in funding costs during 2024, which are driving the margin, along with higher inflation compared to 1Q24. During the first quarter of 2025, the dividend provision for the fiscal year was set at 60%, in accordance with the powers granted to the board of directors by the ordinary shareholders' meeting. 29

Net interest income and readjustments (NII) accumulated as of March 31, 2025, increased by 41.7% compared to the same period in 2023. This increase in NII was primarily due to lower interest expenses due to the effect of the lower monetary policy rate on our funding cost, which fell from 5.3% to 3.9% in 3M25. The Bank's interest-bearing liabilities have a shorter duration than its interest-bearing assets, so our liabilities recognize price changes more quickly than our assets. Following the rapid increase in the MPR that began in mid-2021 and continued throughout 2022, the Central Bank began cutting the MPR in July 2023 from its peak of 11.25%, with five successive cuts to reach 8.25% in December 2023 and continue through 2024, reaching 5.0% in December 2024. Our time deposits represent 37.3% of our funding at the end of March, and these deposits generally have a duration of 30-60 days, so they quickly price in the new rate. This has led to a rapid recovery in net interest income, increasing 36.4% in 3M25 compared to 3M24. Net readjustment income increased 73.6% in 3M25 compared to the same period in 2024, as the UF variation reached 1.2% in 3M25 compared to 0.8% in the same period in 2024. The UF GAP is slightly larger in 3M25 than in 3M24, in response to temporarily higher inflation levels due to the adjustment of electricity rates. In 1Q25, total net interest and readjustment income decreased 1.4% compared to 4Q24, primarily due to lower readjustment income in the quarter. The UF variation was 1.2% in 1Q25, slightly lower than the 1.3% increase in 4Q24, explaining the 7.7% decrease in net readjustment income in 1Q25 compared to 4Q24. On the other hand, interest income in 1Q25 increased by 0.1% in the quarter due to a lower average TPM in the quarter of 5.0% compared to 5.3% in 4Q24. With these funding cost and inflation dynamics, the NIM increased from 2.7% in 3M24 to 4.1% in 3M25 and decreased slightly from 4.2% in 4Q24 and to 4.1% in 1Q25. Our economists are currently projecting a UF variation of 3.6% during 2025 and an average rate of 4.8%. Therefore, we estimate that our NIM for 2025 could be around 4%. 31

Annualized credit loss expense divided by average loans. 2. Balance sheet provisions including additional provisions divided by non-performing loans. During the COVID-19 pandemic, asset quality benefited from state aid and pension fund withdrawals, leading to positive performance over the period. It subsequently normalized in line with the evolution of the economy and the draining of excess household liquidity. Currently, our clients' behavior is reflecting the state of the economy and the labor market, where non- performing loans are higher than pre-pandemic levels. The impaired loan ratio increased from 5.8% in 1Q24 to 6.7% in 4Q24 and 6.9% in 1Q25, meanwhile the non-performing loan (NPL) ratio has remained stable in the quarter. Finally, the expected loss ratio (loan loss provisions divided by total loans) increased from 2.9% in 1Q24 to 3.2% in 1Q25, due to higher provisions in recent periods. 32

Net credit loss expense totaled $139,501 million for the three-month period ended March 31, 2025, an increase of 7.9% compared to the same period in 2024. Similarly, the cost of credit increased from 1.26% as of March 31, 2024, to 1.36% as of March 31, 2025. In the quarter, credit loss expenses increased by 5.4% compared to 4Q24, mainly due to higher provisions for the mortgage portfolio. Therefore, the cost of credit increased from 1.29% in 4Q24 to 1.36% in 1Q25. The non-performing loan coverage ratio (which includes the Ch$205 billion voluntary provisions established by the Board of Directors in recent years) decreased from 142.4% in 1Q24 to 115.4% in 4Q24 and 115.5% in 1Q25. This overall downward trend in coverage is due to the increase in non-performing loans in the commercial and mortgage portfolios, as well as the greater weight of the mortgage portfolio in total loans, which require less coverage due to the associated collateral. Loan quality ratios are also partly affected by the contraction in the loan portfolios.

Provision expenses for consumer loans increased 7.9% in 1Q25 compared to 1Q24 and 17.6% compared to 4Q24, explained in part by a one-time expense related to the change in the provisioning model. The non-performing loan ratio for the consumer portfolio remained stable at 2.2% in the quarter, showing a slight improvement compared to 2.3% in 1Q24, while the impaired loan ratio for the consumer portfolio increased from 4.9% in 1Q24 to 5.2% in 4Q24 and 1Q25. With the increase in consumer provision expenses, coverage increased slightly, reaching 381.3% at the end of March 2025. Commercial loan provisioning expenses increased 39.5% in 1Q25 compared to 1Q24. The increase in provisions is related to the economic cycle and an increase in provisions for non-performing companies. Compared to 4Q24, commercial loan provisions decreased 35.4% in 1Q25 following strong expense growth in this portfolio during 2024, which is already beginning to show improved performance. The commercial NPL ratio increased from 3.5% in March 2024 to 4.1% in December 2024, and remaining more stable in March 2025. The commercial impaired ratio also increased from 7.7% in 1Q24 to 8.6% in 4Q24, before showing a slight deterioration to 8.7% in 1Q25. Therefore, asset quality indicators remained fairly stable in 1Q25. Meanwhile, the NPL coverage ratio for this portfolio decreased from 124.2% in March 2024 to 114.7% in December 2024 and 116.0% in March 2025. Mortgage loan provisions decreased 23.2% in 1Q25 compared to the same period in 2024, while this expense increased 224.9% compared to 4Q24. This is explained by the evolution of the mortgage impaired ratio, which 33

increased from 4.0% in March 2024 to 5.4% in December 2024 and 5.8% in March 2025, indicating that customers are renegotiating their loans. Overall, the mortgage NPL coverage ratio fell from 70.9% in March 2024 to 39.3% in December 2024 and 41.8% in March 2025. In general, the mortgage portfolio has experienced a deterioration in its quality in the last year as a result of the evolution of the macroeconomic scenario related to short and long-term rates and inflation, which has resulted in an increase in the value of our clients' monthly payments. For further information on credit risk and asset quality, see Section 6: Risk. Fees increase 16.8% compared to the same period in 2024, due to a larger customer base and product usage. Net fees increased 16.8% in the twelve months ended March 31, 2025, compared to the same period in 2024, and 6.8% QoQ, primarily due to higher fees on our core products: cards, mutual fund brokerage, checking accounts, and Getnet, driven by the increased customer base and greater product usage. As a result, the recurrence ratio (total net fees divided by structural support expenses) increased from 57.8% cumulatively through March 2024 to 61.8% cumulatively through March 2025, demonstrating that more than half of the Bank's expenses are funded by fees generated by our customers.

This significant increase is explained by increased card usage by our customers and driven by the growth of our customer base, which has increased, reflecting the success of our strategy. 34

Getnet, our acquiring business, has significantly increased the bank's SME customer base, with more than 160,000 SME customers. It currently has more than 296,000 POS machines in operation. Mutual fund brokerage fees grew 21.2% in 3M25 compared to the same period in 2024, and 6.4% QoQ due to customer demand for investment products amid the lower-rate cycle and lower preference for time deposits. Checking account fees increased 11.2% in 3M25 compared to the same period in 2024, while in 1Q25 they increased 0.6% QoQ. Growth in account openings continued during the quarter. This brings the bank's market share of total checking accounts to 22.5% as of February 2025. This also reflects a strong increase in customer demand for US dollar checking accounts, as customers can digitally open these types of accounts through our platform in a few easy steps. We have opened 100,000 accounts in the last 12 months (through February 2025) to reach a total of 481,998 US$ checking accounts, achieving a total market share of 39.5%. Collection fees grew 7.0% in 3M25 compared to the same period last year and increased 1.8% QoQ due to higher collection fees from insurance-related items in the quarter. Insurance intermediation decreased 24.5% in 3M25 compared to the same period in 2024 due to lower commissions generated by personal insurance, both related to lower consumer loan insurance and, most recently, homeowners insurance in the last quarter. This performance is consistent with the lower demand we are seeing for retail loans. Guarantee fees increased 52.0% in 3M25 compared to the same period in 2024 and 39.1% QoQ due to higher fees from our corporate and large enterprise clients, particularly related to Stand-by letters. Loan prepayment fees increased 10.7% in 3M25 compared to the same period in 2024 and decreased 19.6% QoQ, primarily due to a very strong 4Q24 in commercial and consumer loan prepayments, which normalized in 1Q25. In the last item, others, it decreased by 88.7% in 3M25 compared to the same period in 2024, while in 1Q25 a gain was recognized vs. a loss in the fourth quarter of 2024 related to the worse performance of financial advisory in 4Q24. 35

In 1Q25, net financial results recorded a gain of $71,216 million, an increase of 6.5% compared to 4Q24 mainly due to a gain related to the foreign currency position and the sharp depreciation of the peso against the dollar at the end of 2024, which recovered by the end of March 2025. This was partially offset by higher losses related to derivative contracts. For a better understanding of these lines, they are presented by business area in the following table: Net Financial results by business: Non-accounting financial information YTD Var % Quarterly Var % Ch$ million Mar-25 Mar-24 Mar-25/ Mar-24 1Q25 4Q24 1Q24 1Q25/ 1Q24 1Q25/ 4Q24 Client 70,101 64,719 8.3% 70,101 69,627 64,719 8.3% 0.7% Non -client (1) 1,114 (13,852) –% 1,114 (2,768) (13,852) (108.0%) (140.2%) Total net financial transactions 71,216 50,867 40.0% 71,216 66,859 50,867 40.0% 6.5% 1.

These results include interest and mark-to-market effects from the Bank's trading portfolio, realized gains from the available-for-sale portfolio, and other results from the Finance Division. Revenue from client treasury services reached a profit of $70.101 billion in 3M25. This line increased 8.3% in 1Q25 compared to 1Q24 and 0.7% compared to 4Q24, primarily due to higher results related to foreign exchange and fixed-income instruments, both local and offshore. Non-customer treasury totaled a gain of $1.114 billion, compared to a loss in 3Q24 and 4Q24, primarily explained by higher foreign currency hedging results. 36

Efficiency of 35.0% in 1Q25 with operating expenses decreasing 3.7% QoQ. The Bank's efficiency ratio reached 35.0% as of March 31, 2025, better than the 47.4% of the same period in the previous year, with a quarterly efficiency ratio of 35.0%. Furthermore, the cost-to-asset ratio increased to 1.5% in 3M25 compared to 1.4% in the same period last year, in line with a reduction in our total assets. Total operating expenses (which includes other expenses) decreased 1.7% in 3M25 compared to 3M24, driven by lower other operating expenses related to the restructuring of our branch network and the transformation to Work/Café. Core support expenses (personnel, administration and amortization) grew 9.3% in 3M25 compared to 3Q24 and 5.9% compared to 4Q24, mainly due to higher technology expenses. In 1Q25, the Bank celebrated the main milestone of the Gravity project, the migration from the Mainframe to the Cloud. In January, we transitioned processing to our new Cloud, which resulted in higher expenses related to the changeover and write-downs and impairments related to legacy systems. During 2025, the Bank is focused on advancing the execution of its US$450 million investment plan for 2023-2026, focusing on technology initiatives and branch renovations.

Personnel expenses increased by 3.3% in 3Q25 compared to the same period in 2024 due to inflation-related salary adjustments, offset by a 2.9% drop in employee numbers over the same period. Compared to 4Q24, personnel expenses decreased 6.3% QoQ, mainly due to lower expenses on short-term incentives and benefits in 1Q25, in addition to a slight decrease in employees 0.5% QoQ due to the temporary hiring of cashiers for vacation periods in 4Q24. Administrative expenses increased 20.0% in 3M25 compared to the same period in 2024 and increased 22.5% compared to 4Q24 primarily due to higher technology and data processing expenses, largely related to the aforementioned Gravity project. Amortization expenses decreased 3.0% in 3M25 compared to the same period in 2024 and decreased 1.5% QoQ primarily due to lower amortization of internally generated software. Other operating expenses decreased 62.4% in 3M25 compared to the same period in 2024 and 59.4% QoQ, which corresponds in part to restructuring plan expenses recognized during 2024. In 2024, we recorded a total of $43,156 million due to advances in our branch network transformation and progress toward digital banking, which entails a shift from operational to administrative functions. The decrease in this line is also explained by a lower provision and insurance costs related to operational risk, net of recoveries. 38

Section 6: Risks Risk management in 1Q25 focused on strengthening our risk structure in the face of weak economic activity and the labor market. Credit risk Estimate of expected loss: The provisioning estimate is based on expected loss models, in line with Chapter B1 of the CMF's Compendium of Accounting Standards. The loan portfolio is divided between loans analyzed as a group and loans analyzed individually. Within each group, there are different provisioning models for consumer loans, mortgages, and commercial loans. In simplified terms, provisions for most loans are determined using the following expected loss formula: Provisions for individual assessments According to the CMF, the individual assessment of commercial debtors is necessary for companies that, due to their size, complexity or level of exposure, must be analyzed in detail. The analysis of debtors focuses mainly on their credit quality and they are assigned to one of the following portfolio categories: Normal, sub-standard or non-performing portfolio. For this assignment, several risk factors are considered: the industry or economic sector, its activity, the situation of the owners and managers, financial indicators, payment capacity and payment performance. Based on this, the portfolio is classified as: • Normal portfolio: considers debtors whose payment capacity allows them to meet their obligations and commitments and in which there is no foreseeable alteration in their economic and financial situation. The classifications assigned to this portfolio are categories from A1 to A6. • Substandard portfolio: includes borrowers with financial difficulties or significant deterioration in their payment capacity and for whom there is reasonable doubt about their future repayment of principal and interest within the contractual terms, showing a limited capacity to meet short-term financial obligations. The classifications assigned to this portfolio are categories from B1 to B4. 41

• Non-compliant Portfolio: Includes borrowers and related loans whose recovery is considered remote, as they have reduced or no ability to repay. This portfolio includes borrowers who have defaulted on their loans or show clear signs that they will default, as well as those who require a forced restructuring of the debt, reducing the overdue obligation or delaying the payment of principal or interest; and any other borrower who is more than 90 days past due on the payment of interest or principal. The classifications assigned to this portfolio are categories from C1 to C6. As part of the individual assessment of debtors classified as Normal or Substandard, the Bank classifies them into the following categories, assigning them a percentage of probability of default and loss in the event of default (severity), resulting in expected loss percentages. Type of Portfolio Debtor Category Probability of Default (%) Loss due to Default (%) Expected Loss Normal Portfolio A1 0.04 90.00 0.03600 A2 0.10 82.50 0.08250 A3 0.25 87.50 0.21875 A4 2.00 87.50 1.75000 A5 4.75 90.00 4.27500 A6 10.00 90.00 9.00000 Substandard Portfolio B1 15.00 92.50 13.87500 B2 22.00 92.50 20.35000 B3 33.00 97.50 32.17500 B4 45.00 97.50 43.87500 the individual assessment of commercial debtors is necessary for companies that, due to their size, complexity or level of exposure, must be analyzed in detail.

As part of the individual assessment of debtors classified as Normal or Substandard, the Bank classifies them into the following categories, assigning them a percentage of probability of default and loss in the event of default (severity), resulting in expected loss percentages.

Once the expected loss range is determined, the corresponding provision percentage is applied to the amount of the exposure, which includes loans and contingent loans of the same debtor. The provision rates applied to the calculated exposure are as follows: Classification Estimated loss range Provision C1 Up to 3% 2% C2 More than 3% up to 20% 10% C3 More than 20% up to 30% 25% C4 More than 30% up to 50% 40% C5 More than 50% up to 80% 65% C6 More than 80% 90% All debtors' credits must remain in impaired portfolio until their payment or performance capacity is normalized, regardless of the sanctioning procedures for each credit, in particular those that comply with the conditions of Title II of Chapter B-2 of the accounting compendium for banks of the CMF. (Compendio Normas Contables Banco or CNC). Provisions for group assessments Group assessments are appropriate to address a large volume of loans that have small individual balances, mainly disbursed to individuals or small businesses. To determine their provisions, group assessments require the grouping of debtors with similar characteristics in terms of debtor type and credit commitments to determine both the group's payment behavior and the recovery of nonperforming loans, using technically sound estimates 43

and prudential criteria. The model used is based on debtor characteristics, payment history, outstanding loans and defaults, among other relevant factors. The Bank uses methodologies to determine credit risk based on internal and/or standard models to estimate the provisions for the group's assessment portfolio. It considers commercial loans for debtors that are not assessed individually, mortgages and consumer loans (including installment loans, credit cards and overdrafts). This methodology allows the Bank to independently identify the performance of the portfolio in the year and thus determine the provision required to cover losses that arise within one year from the balance sheet date. Clients are segmented according to their internal and external characteristics into clusters or profiles to differentiate the risk of each portfolio in a more appropriate and orderly manner (client-portfolio model). This is known as the profile assignment method, which is based on a statistical construction model that, through logistic regression, establishes relationships between variables – such as delinquency, external performance, sociodemographic data, among others – and a response variable that determines the client's risk, in this case a default equal to or greater than 90 days. After this, common profiles are defined and assigned a Probability of Non-Performance (PND) and a recovery rate based on a historical analysis known as Severity (SEV). Once clients have been profiled and assigned a PND and SEV based on their credit profile, the default exposure is calculated. This estimate includes the client's credit portfolio, including contingent credits, less any amount recoverable through enforceable guarantees (for non-consumer credits). Notwithstanding the foregoing, in order to establish provisions mortgage, commercial and consumer loans, the Bank must establish minimum provisions in accordance with the standard method established by the FMC for this type of loans. Although this standard model constitutes a minimum prudential baseline, it does not exempt the Bank from its responsibility to have its own internal methodologies for determining sufficient provisions to protect the credit risk of this portfolio. The impaired portfolio includes all outstanding and contingent loans of borrowers who are more than 90 days past due on any interest or principal. It also includes borrowers who have been granted a loan to refinance a loan that is more than 60 days past due and borrowers who have undergone a forced debt restructuring or partial debt forgiveness. On April 27, 2022, the latest amendment to the Compendium of Accounting Standards (CNC) for Banks established that, for the formation of the group portfolio, commercial exposures, other than student loans, associated with the same counterparty, should not exceed a threshold of 20,000 UF and 0.2% of the group portfolio. The Bank has implemented this amendment, generating a net impact of MM$2,344 in higher provisions for credit risk. 44

Credit quality of debtors During 2024, our clients showed signs of more stressed payment behavior, particularly in the mortgage and commercial portfolios. Therefore at the end of March 2025, the impaired ratio reached 6.9%. The mortgage portfolio deteriorated during 2024 due to the drain on household liquidity and the increase in monthly payments in recent years. Therefore, compared to five years ago, in an environment with a weaker labor market, we have seen more delinquencies. Since the second half of 2024, with more stable financial conditions, clients began to renegotiate, which is reflected in the mortgage impaired loan ratio, which has increased from 4.0% in March 2024 to 5.8% in March 2025. It is important to remember that mortgage loans have property as collateral and an LTV of around 60%. Regarding the commercial portfolio, in 2024 certain industries such as real estate and agriculture came under pressure, which led to the commercial impaired ratio increasing from 7.7% in March 2024 to 8.7% in March 2025. In recent months, we have seen that the asset quality of this portfolio is more stable and showing an improving trend. During 1Q25, provisioning expenses increased 5.4% QoQ and 7.9% YoY, reflecting the evolution of asset quality. As a result, the non-performing loan coverage ratio, including additional provisions, reached 115.5% in March 2025, and the expected loss ratio (credit risk provisions divided by total loans) increased to 3.2%. The overall downward trend in coverage is due to the increase in non-performing loans in the commercial and mortgage portfolios and also a greater weight of the mortgage portfolio in total loans, which require less coverage due to the associated collateral. Loan quality ratios are also partly affected by the contraction in the loan portfolios. 46

Distribution by economic sector By economic sector, the Bank's portfolio is highly diversified, with no significant exposure to any particular industry, increasing the possibility of maintaining a stable portfolio over time. 8.0% 9.0% 13.6% 20.0% 27.9% 43.0% 42.7% 14.3% 0.1% Interbank loans Consumer Mortgage Commercial Social services and other community services Trade Real estate services Agriculture, livestock, fishing, forestry, etc. Manufacture Electricity, gas and water Construction Transport Financial services Telecommunications Mining Oil and natural gas Total portfolio Commercial Portfolio 0% 20% 40% 60% 80% 100% Market risk There are four main market risks that can affect the Bank: exchange rate, inflation, interest rate, and liquidity. Their measurement and control are the responsibility of the Market Risk Management Department, which is part of the Risk Division. The limits are approved by the various committees responsible, a responsibility that lies primarily with the Market Committee and the Assets and Liabilities Committee (ALCO). The main market risks are also reviewed by the Comprehensive Risk Committee. The Financial and Capital Management areas, as part of the Finance Division, have the following functions, which are supervised and controlled by the ALCO and Risk Management: • Optimizing the cost of liabilities by seeking the most efficient financing strategies, including bond issuance and bank lines. • Manage regulatory limits on short- and long-term liquidity. • Inflation risk management and exposure. • Manage local and foreign currency exchange rate risk. • Capital adequacy and requirements. Liquidity risk 48

The Financial Management area manages liquidity risk using a portfolio of liquid assets to ensure that the Bank always maintains sufficient liquidity to cover short-term fluctuations and long-term funding, complying with internal regulatory liquidity requirements. The Financial Management Division receives information from all business units on the liquidity profile of their financial assets and liabilities, as well as the breakdown of other projected cash flows arising from future business. Based on this information, the area maintains a portfolio of short-term liquid assets, composed primarily of liquid investments, loans, and advances to other banks, to ensure the Bank has sufficient liquidity. The business units' liquidity needs are covered through short-term transfers from Financial Management to cover short-term fluctuations and long-term funding to address all structural liquidity needs. The Bank monitors its liquidity position daily, determining future inflows and outflows. Additionally, stress tests are conducted at the end of each month, using a variety of scenarios covering both normal and fluctuating market conditions. The liquidity policy and procedures are subject to review and approval by the Bank's Board of Directors. Periodic reports are generated by the Market Risk Department, which detail the liquidity position of the Bank and its subsidiaries, including exceptions and corrective measures adopted. These reports are periodically submitted to the ALCO for review. The Bank obtains demand and fixed-term deposits from retail, Middle-market, and Corporate banking. The Financial Management Department obtains financing from correspondent banks, debt instruments, commercial paper, and wholesale term deposits. Although most obligations with banks and debt instruments mature in more than one year, customer and wholesale deposits tend to have shorter maturities, and a large proportion of them are payable within 90 days. The short-term nature of these deposits increases the Bank's liquidity risk; therefore, the Bank actively manages this risk through continuous monitoring of market trends and price management. High-quality liquid assets High-quality liquid assets (HQLAs) are an essential component of liquidity risk management. They consist of balance sheet assets, primarily composed of financial investments that are not pledged as collateral, have low credit risk, and have a deep secondary market. Under Basel III standards, these assets are divided into three tiers, with Tier 1 assets being the most liquid and Tier 3 assets being the least liquid. As of March 31, 2025, the Bank's ALAC amounted to $8,376,486 million and corresponded mainly to Level 1 liquid assets, composed primarily of bonds of the Republic of Chile, the Central Bank of Chile, and the United States Treasury. 49

Liquid Assets (Consolidated Ch$ million) Tier 1: Available, 1,526,665 Tier 1: Fixed income, 6,845,705 Tier 2: Fixed income, 4,116 In terms of liquidity, the main metrics managed by the Bank's Finance Division are the following: 1. Liquidity Coverage Ratio (LCR). 2. Net stable financing ratio (NSFR). LCR The Liquidity Coverage Ratio (LCR) measures the percentage of liquid assets over net cash outflows. This indicator is required by Basel III standards and provides a sustainable maturity structure for assets and liabilities, allowing banks to maintain a stable funding profile relative to their activities. As of March 31, 2025, this ratio for Banco Santander Chile was 192.9%, above the minimum (100%). This reflects the conservative liquidity requirements established by the Board of Directors through the ALCO Committee.

NSFR This indicator is a local regulatory version of the NSFR required by Basel III, which provides a sustainable maturity structure for assets and liabilities so that banks maintain a stable funding profile relative to their activities. As of March 31, 2025, the NSFR was 104.3%.

To manage this risk, Banco Santander performs a sensitivity analysis for local and foreign currencies. Through simulations, limits are set on the maximum loss that rate movements can have on the capital and net financial income budgeted for the year. 31 de marzo de 2025 Effect on financial income Effect on capital Financial management portfolio – local currency (in $MM) Stop loss 175,196 370,271 High 33,072 186,784 Low (1,723) 111,997 Average 11,134 154,517 Financial management portfolio – foreign currency (in millions of US dollars) Stop loss 42,936 190,824 High 8,553 68,145 Low 442 47,615 Average 2,828 55,685 Financial management portfolio – consolidated (in $MM) Stop loss 175,196 370,271 High 30,570 357,867 Low — 279,778 Average 15,466 319,759 51

VaR trading portfolio In the case of the trading portfolio, risk is estimated and managed using Value at Risk (VaR) limits, remaining within established risk limits. Due to the rules established by the Asset and Liability Committee (ALCO), the Bank must not have significant exposure to foreign currencies; therefore, all foreign exchange risk is included in the trading portfolio and is measured and controlled using Value at Risk (VaR) limits. The table below shows the evolution of the Bank's consolidated VaR of the trading portfolio, which includes the exchange rate risk and the interest rate risk of the trading portfolio. VAR March 31, 2025 US$ million Consolidated: High 3.19 Low 1.53 Average 1.53 Fixed income investments: High 2.72 Low 1.41 Average 1.72 Foreign currency investments High 2.54 Low 0.14 Average 1.11 Inflation risk The bank has assets and liabilities that are indexed based on the variation in the Unidad de Fomento (UF). In general, the bank has more assets than liabilities in UF, and therefore, moderate increases in inflation have a positive effect on indexation revenues, while a decrease in the value of the UF negatively affects the bank's margin. To manage this risk, the ALCO establishes a set of limits on the difference between assets and liabilities denominated in UF as a percentage of interest-earning assets.

Build a digital bank with branches that offer well-targeted products and services to grow the customer base. Lead the customer experience by leveraging global and market scale, network capabilities, and technology to accelerate profitable growth. 58

Main advances of our strategy Digital Bank with Work/Cafés Our first strategic pillar is based on cutting-edge technology and customer-focused processes and products. We are building a bank with strengths in digital channels that enable secure, fast, and easy-to-use digital onboarding. We offer our Life, Más Lucas, and Mas Lucas Joven accounts for the mass segment, and our PYME Life account, along with payment services through Getnet for entrepreneurs and small and medium-sized businesses. These initiatives not only encourage our customers to become increasingly digital, but are also increasing financial inclusion in these segments through an initial approach through transactional services, with the potential to expand the offering of other products and financing options, such as credit cards and loans. The other part of the first pillar is the transformation of our branches to Work/Café, assessing the needs of our customers in different areas and providing branches that not only meet their financial needs but also provide a pleasant environment for them to come to us.

Similarly, digital customers grew by 6.6% year-over-year, due to the success of its digital initiatives. Digital clients: As a result of these efforts, the Bank's market share in checking accounts remains strong. According to the latest publicly available information, which is as of February 2025, our market share reaches 22.5% in checking accounts, which includes products such as Santander Life and PYME Life. These figures do not include our Más Lucas checking account. On the other hand, demand for dollar checking accounts continues to grow. As of February 2025, we have a 39.5% market share and have opened 100,000 dollar checking accounts in the last twelve months, thanks to the ease of opening these accounts online and continued customer demand for these types of accounts. Furthermore, digital customers continue to grow, reaching more than 2.2 million digital customers, representing 88% of our active customers. The majority are current account holders. The most popular products are deposits, credit cards, mutual funds, and general insurance.

Santander Life continues to be the leading contributor to new customer growth with a digital onboarding process for opening a checking account. Santander Life customers are monetizing rapidly while achieving a high Net Promoter Score (NPS) for the onboarding process. Más Lucas is the first 100% digital checking and savings account for the mass market. This product charges no maintenance or transaction fees and is remunerated monthly based on the balance maintained. In this way, the Bank aims to provide greater access to these simple banking products and reinforce Santander's commitment to financial inclusion. Since its launch in March 2023, Más Lucas has more than 350,000 customers and has maintained an average of 20,000 open accounts per month in recent months. In June 2024, we launched Más Lucas Joven, a checking account for people between 12 and 17 years old. Like the Más Lucas account, this account is free and also pays monthly interest based on the average balance. With this, we seek to attract customers in their first encounter with a bank, offering them digital products with the ease of paying by debit card and online transfers. It has had good traction, with approximately 7,000 accounts being opened monthly and nearly 100,000 young customers using this product to date.

We continue to grow in Work/Café branches As of March 2025, we have a total of 91 Work/Café branches, including Work/Café Investments, Start-Up, Expresso, and regular Work/café branches. We have closed nine branches in the last 12 months, including Select branches, aimed at higher-income customers, and traditional branches. In total, we have 237 branches, a 3.7% decrease compared to last year. In 4Q22, we launched Work/Café StartUp, an initiative that aims to offer a comprehensive solution to all the needs of entrepreneurs, specifically increasing banking access, conducting pilot programs with the Bank, and even offering financing. It's aimed at companies with three main characteristics: first, they are just starting out and experiencing accelerated growth; second, they must include technology as part of the value proposition; and third, they must be scalable to address a real problem. Then, in 1Q23, we launched Work/Café Expresso, our new transaction centers with cashier or self-service services, a service desk, card printing machines, and lockers for product delivery, all in a Work/Café format, where our customers can conduct their transactions in an efficient and secure environment, providing a better customer experience. These high-tech branches provide greater efficiencies in our cash management, allowing us to continue consolidating our branch network. And finally, in 4Q23, we launched Work/Café Inversiones, a new community space designed to help people improve their financial well-being. Clients and potential clients will be able to access specialized advice, talks, and workshops on various topics that will help them learn and understand more about investment instruments, the impact of market movements, and how to prepare for their various personal projects. Through concrete initiatives such as the opening of this new space, the Bank continues to clearly advance its mission to help people thrive. With all of the above, we continue to find efficiencies in our branch network, with more than 38% of our branches now cashless.
