Section 1: Key information Summary of Results ROAE1 of 20.7% in 2Q242 and 15.8% in 6M243. In the second quarter of 2024 (2Q24), the Bank's net income attributable to shareholders totaled $217,724 million ($1.16 per share and US$ 0.49 per ADR), reflecting an increase of 81.1% compared to the previous quarter, with an ROAE of 20.7%. As of June 30, 2024, the Bank's net income attributable to shareholders totaled $337,976 billion ($1.79 per share and US$0.76 per ADR), reflecting an increase of 28.6% compared to the same period of the previous year, along with an ROAE of 15.8%. The increase in results in the quarter is explained by an increase in the Bank's main income lines, with operating income increasing by 19.4% in the quarter, driven by a better interest margin and adjustments. Strong recovery in MIN4 to 3.6% in 2Q24 and 3.1% in 6M24. Net interest and readjustment income (NII) as of June 30, 2024 increased by 54.5% compared to the same period in 2023. This increase in NII was due to higher interest income due to the effect of the lower monetary policy rate on our funding cost and partially offset by lower readjustment income due to lower inflation in the period. In 2Q24, total net interest and readjustment income increased by 26.4% compared to 1Q24. This is explained by higher interest income due to lower funding costs and also by higher net income from readjustments due to the greater variation of the UF in the quarter. It is important to mention the first payment of the FCIC, a line of credit granted by the Central Bank during the pandemic, which was made on April 1. This generated a 4.8% decrease in interest-generating assets in the last quarter. With these dynamics of funding costs, inflation and decrease in interest-generating assets in the last quarter, the NIM increased from 2.1% in 6M23 to 3.1% in 6M24 and from 2.0% in 2Q23 and 2.7% in 1Q24 to 3.6% in 2Q24. 4 1 Annualized net income attributable to owners of the bank divided by the average equity attributable to equity holders.2 The second quarter of 2024.3 The six months accumulated as of June 30, 2024. 4 MIN: Net interest margin. Net interest income and annualized adjustments divided by interest-earning assets

Net commissions increase 6.5% in the quarter, with recurrence5 levels of 55%. Net fees increased 6.5% QoQ6 due to increased customer numbers and greater use of products such as mutual funds, cards and current accounts. As a result, the recurrence ratio (total net fees divided by total expenses) is 55.0% in 2Q24, with more than half of the Bank's expenses being financed by the fees generated. In the first half of 2024, fees decreased by 1.4% compared to the same period in 2023, mainly due to lower card fees due to the impact of interchange fee regulation and lower fees earned on financial advisory services. However, fees on our other core products continue to trend well. Solid capital levels with a BIS7 ratio of 17.4% and a CET18 of 10.6%. Our total BIS ratio reached 17.4% as of June 30, 2024 and the CET1 ratio remains solid at 10.6%, even considering that we increased the dividend provision for the 2024 income from 30% to 60% in June 2024. Risk- weighted assets (RWA) increased 0.5% since December 31, 2023 and decreased 1.9% QoQ, explained by a decrease in credit risk-weighted assets. Additionally, in January 2024, the CMF announced the Pillar II charges for six banks in the Chilean system, and we highlight that, on this occasion, they did not assign a Pillar II charge to the Bank. 5 5 Recurrence: Net commissions divided by operating expenses.6 Quarter versus quarter (2Q24 vs 1Q24) 7 Regulatory capital divided by risk-weighted assets, according to CMF BIS III definitions8 Core capital divided by risk-weighted assets, according to CMF BIS III definitions.

Macroeconomic environment All of our operations and substantially all of our customers are located in Chile. Accordingly, our financial condition and the results of our operations depend substantially on the economic conditions prevailing in the country. Economic activity started 2024 more positively than the previous year, however, in recent months it has shown a slight slowdown, with a growth of 1.1% YoY to May 2024. As a result, we lower our GDP growth estimate for this year, from 2.8% to 2.5% annually, driven mainly by consumption and external demand. The labor market continues to gain dynamism with the participation rate approaching pre-pandemic levels. However, salaried employment has fallen more than expected while self-employment (mainly associated with the informal sector) drives the creation of new jobs. On the other hand, real wages continue to rise, which together with employment growth could boost consumption. The higher price of copper in recent periods has helped improve the terms of trade, which gives an additional boost to the trade balance. Finally, there is an increase in projects submitted for environmental assessment along with an upward trend in approvals, which improves investment prospects, especially for 2025. CPI (12 months) Ju n- 21 Se p- 21 De c- 21 M ar -2 2 Ju n- 22 Se p- 22 De c- 22 M ar -2 3 Ju n- 23 Se p- 23 De c- 23 M ar -2 4 Ju n- 24 0.0 5.0 10.0 15.0 Inflation followed the expected trajectory in the first half of 2024, although inflationary pressures are expected in the following months due to a renewed exchange rate depreciation, the oil rebound, and the impact of the unfreezing of electricity rates. Therefore, the CPI estimate is raised from the previous 3.9% to 4.3% for 2024 and from 3% to 3.4% for 2025. The UF variation in 2Q24 increased compared to the previous quarter, reaching 1.3% vs. 0.8% in 1Q24. We expect that for 2024 the UF variation will decrease to 4.0% (4.8% in 2023) and to 3.4% in 2025. The volatility of the exchange rate is explained by the fluctuations in the price of copper and the global dollar and, above all, the expectations of the rate differential between the Central Bank of Chile and the Fed. In the baseline scenario, we estimate that the parity will continue with a gradual process of convergence towards its equilibrium values. However, given the scenario of uncertainty regarding the global monetary normalization process that would keep the multilateral dollar at stronger levels, we raise our exchange rate projection to $890 by December 2024. 9

During 2024, the cuts have persisted, although more gradually. At the June meeting, the Central Bank cut the rate by 25bp, to 5.75%, and highlighted that the adjustments during the second half of the year would be less intense. This is due to higher inflation prospects in Chile and the evolution of the external scenario. With this, we estimate that the Central Bank could take the MPR to 5.25% at the end of 2024 and continue with more cuts next year, to reach a neutral rate of 4.25% in the first quarter of 2026.

Tax reform Chile's Ministry of Finance submitted a tax reform proposal to Congress in July 2022, but it raised several criticisms and doubts from both the private and political sectors, in particular, regarding those aspects that could impact the country's competitiveness and investment. The proposed reform was rejected in March 2023. 10

Meanwhile, the government is carrying out a fiscal pact, seeking to modernize the current tax system, prioritize spending, greater transparency of state services and fiscal supervision. As part of this, they hope to encourage investment, productivity and formalization of the economy while closing opportunities for tax evasion. In this context, on January 29, 2024, the government submitted to Congress the Tax Compliance Bill, which seeks to collect 1.5% of the Gross Domestic Product (GDP) by reducing tax avoidance. This initiative is one of the commitments in the Pact for Economic Growth, Social Progress and Fiscal Responsibility. The initiative, which does not imply increasing the tax burden on taxpayers, is composed of 7 thematic pillars: i) Modernization of the tax administration and the Tax and Customs Courts; ii) Control of informality; iii) Tax crimes; iv) Aggressive tax planning; v) New powers for the Taxpayer's Ombudsman; vi) Regularization of tax obligations; vii) Institutional strengthening and integrity. Pension Reform In November 2022, the Chilean government submitted a new pension reform bill to Congress, which was rejected. A technical panel for pension reform was subsequently formed, which brings together the Government with parliamentarians and experts appointed by the political parties that decided to participate. After the last session in July, the report with the recommendations of this panel was published, where the points of consensus are: 1) Mechanisms to increase savings: they agree to increase the contribution by 6% at the employer's expense, in addition to including a modernization of the collection mechanism. 2) Bidding for the stock of members: this consists of randomly selecting 10% of the members and awarding the administration of the pension savings to the bidder with the lowest commission, who must maintain that price for ten years. The members who are tendered may withdraw from the bidding or change AFPs at any time, respecting their freedom of choice. 3) Commission per flow is maintained: maintaining the remuneration of the AFPs based on a commission on people's salaries, that is, independent of the performance of pension savings management. 4) Generational funds: change the current AFP multi-funds towards generational funds. 5) Risk insurance: compensation to women for longer life expectancy. 6) Additional insurance modalities: solidarity between generations for transitional periods, focused on women and groups that contribute for more years. 7) Changes in the Superintendency of Pensions: need to make changes to strengthen the superintendency by transforming it into a collegiate body similar to the CMF. Pillar 2 – Basel III Implementation In the context of the implementation of Basel III in Chile, on December 12, 2023, the CMF put out for consultation adjustments to the regulations on capital requirements for banks, referring to the component known as Pillar 2. In this new cycle, the CMF is evaluating and quantifying the non-traditional material risks to which each bank is exposed, to determine whether or not the application of regulatory capital charges under Pillar 2 is appropriate. The risks covered in Pillar 1, which are considered traditional risks, are: credit, market, and operational risks. And the non-traditional risks that Pillar II seeks to cover are (and which depend on the business model of each bank): market risks of the banking book; credit concentration; reputational; strategic; cybersecurity; geopolitical; climate, among others. 11

Subsequently, on January 17, 2024, the CMF applied the current regulations on additional asset requirements according to pillar II, where the Council resolved to apply said requirements to the following institutions: Banco Bice, Banco BTG Pactual Chile, Banco Consorcio, Banco de Chile, Banco del Estado de Chile, Banco Internacional, Banco Security, HSBC Bank (Chile) and Scotiabank Chile. The above decision is based on the capital self-assessment process through the Effective Equity Self-Assessment Report (IAPE) that all banks carry out annually in the month of April. In this report, the banks themselves determine their internal target of effective equity necessary to cover their material risks over a horizon of at least three years. And, in addition, from the IAPE corresponding to the year 2023, it also considers risks for which there is no measurement standard, such as market risk in the banking book and credit concentration risk. Finally, these new charges respond entirely to credit concentration risk and market risk in the banking book. For this last risk, the CMF has proposed changing the definition of a typical bank and eliminating the 15% CET1 threshold for the impact on economic value. This discussion will take place in the coming months, so it is likely that the Pillar II charges will change for all banks in the coming years. Interchange fees In February 2023, the Committee for the Setting of Exchange Rate Caps proposed new rate caps. These were approved at the end of April 2023 and will be implemented gradually. Card type Current rate In 6 months (Oct-23) In 18 months (Oct-24) Debit 0.6% 0.5% 0.35% Credit 1.48% 1.14% 0.80% Prepaid 1.04% 0.94% 0.80% In order to assess the effects of the gradual implementation of the process of determining limits on interchange rates, the Committee agreed to carry out 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 that are reasonably foreseeable, of the second reduction; and (iv) on all aspects of the market that are relevant to the fulfillment of the Committee's objectives established in the aforementioned law. New regulations for consumer provisions During 2022, the CMF published a draft for a new standardized provisioning model for consumer loans for banks. The CMF estimated an impact for the entire industry of about US$1 billion and the Bank estimated an impact of an expense of between Ch$100 billion and Ch$150 billion. In October 2023, the CMF published a second draft for consultation for the same model, estimating an initial impact of US$487 million for the entire system. Finally, in March 2024, the CMF published the final regulations for this model, which will come into force in January 2025. The impact for the entire system is close to US$454 million and for the Bank it is between Ch$85 billion and Ch$100 billion. As reported by the CMF, voluntary provisions already established in previous periods can be used to constitute this additional requirement. 12

Fraud Law In early April, improvements were approved to the Fraud Law No. 20,009 to combat the recent increase in cases of unknown bank transactions (better known as self-fraud) and other crimes associated with opportunistic behavior, which have strongly affected financial institutions. Certain aspects are modified, such as, for example, i) the repayment terms for an unknown transaction, ii) the requirement of a sworn statement from the user and a complaint to a criminal authority to make the fraud claim effective, iii) a new suspension procedure is created, regardless of the amount claimed, when the issuer has sufficient evidence of the existence of fraud or gross negligence on the part of the user, and then submits the background information to the respective local police court requesting authorization to maintain said suspension, among others. Consolidated debt In early June, the Consolidated Debt Law was approved, which creates a public and free Consolidated Debt Registry (Redec), which will be administered by the Financial Market Commission (CMF). The new law establishes that new institutions that did not do so before will be required to report to the CMF current loans granted to natural persons, such as the administrative agents of endorsable mortgage loans; cajas de compensación (employee benefit funds); credit card issuers (supervised by the CMF); securitization companies; credit advisory entities regulated by the Fintec Law; and any other entity supervised by the CMF, which it determines through a General Law. Furthermore, it is made clear that the person is the owner of his/her data and is guaranteed the right to protection of said data, under the supervision of the CMF, by establishing his/her rights to update, rectify and cancel the information, along with defining severe sanctions for negligent or malicious access or use of Redec information. In order to access the information in the registry, reporters must have prior consent, which will be granted for the sole purpose of evaluating their commercial or credit risk for a specific operation and for a limited period. Fintech and Open Finance Law At the beginning of July, the Financial Market Commission (CMF) published the regulations governing the Open Finance System (SFA) or open finance of the Fintech Law, which will come into force 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 compulsorily join the SFA to provide the information that the user decides to share with other participating institutions, after giving their consent. In addition, the CMF established the rules for institutions that voluntarily decide to register with the SFA and thus offer financial services to users. The implementation period of the SFA will be gradual, depending on the role played by each participant within this scheme. The first stage has a 24-month period for its entry into force, a period that will be used for the adaptations required for implementation by each of the participants. In addition, during this period they will develop the technical manuals with the specifications. After this time, the standard contains an implementation schedule that 13

begins with the progressive delivery of information that banks and payment card issuers must share within the following 18 months. Then, in the 18 consecutive months, the obligation will begin for savings and credit cooperatives supervised by the CMF, insurance companies, fund managers and cajas de compensación (employee compensation funds), among others. Therefore, the total implementation of the standard is estimated to take five years. Regulation and supervision In Chile, only banks may maintain current accounts for their clients, conduct foreign trade transactions and, together with regulated non-bank financial institutions such as cooperatives, accept time deposits. The main authorities regulating financial institutions in Chile are the Financial Market Commission (CMF) and the Central 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 Corporations Law governing corporations, except for certain provisions that expressly exclude them.

Section 3: Segment information Segment information is based on the Financial Information presented to senior management and the Board of Directors. The Bank has aligned the segment information consistently with the underlying information used internally for management reporting purposes and with that presented in other public documents of the Bank. The Bank's senior management has been determined to be primarily responsible for the Bank's operating decisions. The Bank's operating segments reflect the Bank's organizational and management structures. Senior management reviews internal information based on these segments to assess performance and allocate resources. During 2024, the Bank will maintain the general criteria applied in 2023, adding the opening of Retail (formerly Individuals and SMEs) in Retail and Wealth Management & Insurance. For comparative purposes, the 2023 data has been restated to include these modifications.

In addition to companies in the real estate sector, specialized services are offered for the financing of mainly residential projects, with the intention of increasing the sale of mortgage loans. 15

Within the retail segment, there are individuals, companies and Santander Consumer (car financing) detailed below: • Individuals: Santander Life continues to be a major contributor to new customer growth, with a digital onboarding process for opening a current account. Santander Life customers are quickly monetizing while earning a high Net Promoter Score (NPS) for the onboarding process. 18

In addition, in order to continue with our commitment to financial inclusion, we launched “Más Lucas”, the first profitable checking account and savings account, 100% digital for the mass market. This product does not charge a maintenance or transaction fee, and the checking account pays a fixed monthly rate based on the average balance held in the account. • Santander Consumer (auto financing): This business has been very proactive in increasing alliances with different car manufacturers, achieving 14 new commercial alliances in 2023 and being the first financing option for more than 30 brands. Also in March, the FNE approved the purchase of an automotive loan portfolio with Servicios Financieros Mundo Crédito Spa (auto financing company). • Companies: We continue to open digital current accounts for these clients, which, together with the services offered by Getnet, complete the range of solutions for their businesses. Retail Banking loans increased 4.7% YoY and 1.1% QoQ. Mortgage loans continued to increase 1.3% QoQ and 2.5% since December 31, 2023, in line with the increase in UF, which increased 1.3% QoQ and 2.1% so far this year, so there is not enough new mortgage origination for portfolio growth. On the consumer side, it increased 1.9% since December 31, 2023 and 1.2% QoQ, mainly driven by credit cards that grew 3.5% so far this year and the purchase of Santander Consumer's portfolio of about Ch$ 50,000 million in 2Q24. On the side of total deposits in this segment, they decreased by 2.6% year-on-year and also in the quarter due to a fall in demand deposits to a greater extent, added to a fall in time deposits as well, where we have seen a transfer of liquidity from our clients to Mutual Funds as a consequence of the decrease in the MPR that makes time deposits less attractive for clients. Results: Retail banking's net contribution increased 4.9% YoY, due to higher revenues from core lines and lower provision expenses. Margins increased 6.3% YoY due to a better funding mix and loan growth. Fees in this segment increased strongly by 7.9% YoY, driven by fees from current accounts, mutual funds and insurance as well as fees generated by Getnet. Provisions increased 4.3% YoY, due to higher provision expenses in the consumer portfolio during this second quarter compared to the first quarter. Operating expenses decreased 0.4% YoY as the Bank continues its digital transformation. Compared to 1Q24, retail banking's net contribution increased 13.7% QoQ due to lower provisions than the previous quarter. The margin increased 2.5% QoQ due to higher inflation in the quarter. Commissions in this segment increased 3.0% in the quarter mainly as a result of higher commissions from mutual fund brokerage (Santander Asset Management). Provisions decreased 5.7% QoQ mainly due to lower provisions in the mortgage portfolio, which in 1Q24 were already provisioned in line with customer behavior, which is following the evolution of the labor market. Operating expenses decreased 2.4% QoQ, due to lower amortization expenses, offset by higher personnel expenses in the quarter due to the seasonality affecting 1Q24. 19

Wealth Management & Insurance: This unit aims to unify the investment offering, allowing for greater consistency across all segments and communication of products and services. Its focus is on generating a specialized strategy for investments in each segment, establishing unique digital and communication development plans. The core businesses are insurance and the distribution of investment instruments for the Retail segment and Private Banking.

Deposits increased by 7.7% QoQ and 22.6% YoY, mainly due to time deposits in CLP. Results: Net contribution from Wealth Management & Insurance increased 10.3% YoY due to higher total revenues which increased 10.6% YoY explained by a higher spread in cards and commercial loans in this segment and higher commissions related to mutual funds and insurance. This was offset by higher provisions due to a deterioration in mortgage and consumer loans. Operating expenses decreased 5.0% YoY due to a decrease in amortizations. In the quarter, Wealth Management & Insurance's net contribution increased 23.0% QoQ due to a 7.8% increase in total revenues due to higher inflation in the quarter. This was offset by higher provisions due to deteriorating client performance in the quarter. Expenses decreased 12.1% QoQ due to lower technology amortization. 20

Deposits fell by 5.4% QoQ and 2.9% YoY, mainly due to lower liquidity and a less attractive rate on time deposits. The main strategic objective of this segment is to focus on total customer profitability, in lending and non-lending activities. Results: Middle-market's net contribution decreased by 4.5% YoY. Total revenues increased by 0.5% due to an increase in commissions. This was offset by an increase in provisions of 64.7% YoY due to a worse performance in some industries such as construction and real estate in recent years and the agricultural sector, which was affected by the intense rains and floods caused by the "El Niño" phenomenon, which mainly affected the central regions of Chile where there are many crops and which had not seen such heavy rains in many years. Expenses increased by 15.2% YoY due to higher expenses in technological projects. In the quarter, Middle-market's net contribution decreased by 7.8% QoQ due to an increase in provisions explained in the previous paragraph. Total revenues increased by 2.0% QoQ mainly due to higher commissions. Finally, expenses increased by 2.2% in line with the progress of technological initiatives in this segment. 21

Deposits increased by 11.1% YoY, due to increased demand for time deposits during the period of high rates, but with the continued rate cuts by the central bank, time deposits became increasingly unattractive, decreasing by 6.6% in the quarter. Results: The net contribution of this segment decreased by 8.6% YoY. Total revenues fell by 3.2% YoY due to lower financial transactions due to lower demand for FX products, but on the other hand, commissions improved thanks to greater securities brokerage and financial advisory services. On the provisions side, there was a build- up of provisions compared to the release that occurred in the same period of the previous year, due to a deterioration of some clients in recent months. Expenses increased by 4.8% YoY due to higher amortization of technology and administrative costs. In the quarter, CIB's net contribution increased by 7.1% mainly due to higher total revenues in the quarter due to higher inflation, which increased net interest and adjustment income by 1.2% QoQ, higher commissions by 8.5% QoQ and higher financial transactions by 11.8%. Expenses increased by 5.9% due to higher technology and variable remuneration expenses. 22

During the period we had a loss from interest income and readjustments of $25 billion due to the cost of funding managed by the ALCO, which becomes less negative according to the MPR cuts. It is important to note that the last payment of the FCIC was made on July 1, 2024. 23

Section 4: Balance sheet and results Balance sheet Retail loans grow with soft trends, while commercial loans contract due to lower dynamism Total loans decreased 1.8% QoQ and 0.7% compared to December 31, 2023. The retail banking portfolio (mortgage and consumer) continued to grow modestly, while the slower dynamism of the economy, together with exchange rate effects, resulted in contractions in the commercial portfolio. In addition, during the quarter, Bansa S.A. was excluded from the Bank's consolidation, becoming part of another entity of the Santander Group. Bansa's main activity is the financing of revolving inventory lines of automotive dealers, totaling approximately Ch$ 219 billion in commercial loans, before being excluded from the Bank's consolidation (approximately 0.5% of the total portfolio).

Total gross loans from provisions at amortized cost. Approximately 59% of our portfolio is indexed to the UF, mostly mortgage loans and around 37% of commercial loans. Regarding foreign currency loans, around 23% of commercial loans (from the Middle-market and CIB segments) are denominated in foreign currency, mainly in US dollars. In the last quarter, the Chilean peso has appreciated by 4.0% and depreciated by 7.8% since December 2023. Therefore, commercial loans denominated in US$ have shown volatility in their value in pesos. These loans have also been impacted by a slower dynamism of the economy in recent months, therefore commercial loans decreased by 4.1% since December 31, 2023 and 5.5% QoQ. Mortgage loans continue to grow slightly above inflation, reaching a growth of 2.5% since December 31, 2023 and 1.3% QoQ. In recent periods, the origination of new mortgage loans has decreased due to high inflation and rates, however, since the second half of 2023, mortgage loans have grown again in real terms as customers adjusted to market conditions, although demand remains weak. Consumer loans increased 1.2% QoQ and 1.9% as of December 31, 2023. Between the end of 2019 and 2021, credit card loans decreased 7.0% as customers cut back on large purchases such as travel and hotels, boosting 24

credit card loans. At the same time, many customers paid off credit card debt with liquidity from government transfers and pension fund withdrawals.

In recent quarters, we have seen an acceleration of credit card lending, mainly related to the increased use of cards.

Therefore, changes in business volumes and results may reflect business trends and customer migration effects. Retail banking loans grew by 0.3% from December 31, 2023 and by 1.2% from March 31, 2024, driven by the slight growth seen in consumer and mortgage loans. Wealth Management & Insurance increased by 7.0% from December 31, 2023 and by 3.8% from March 31, 2024 mainly due to mortgage and card products and in the quarter, also due to commercial loans, Comex. The Middle-market segment's loan portfolio decreased by 3.8% since December 31, 2023 and by 5.6% since March 31, 2024, mainly due to the lower economic activity in general in recent months and a slight appreciation of the exchange rate, reducing the amount in pesos of loans denominated in dollars, mainly to our importer and exporter clients. 25

Loans in the CIB segment decreased by 23.3% since December 31, 2023 and by 28.7% since March 31, 2024, mainly due to a drop in loans and factoring, related to lower economic activity in the quarter.

In anticipation of the payment of the FCIC, a credit line provided by the Central Bank to banks during the pandemic, the Central Bank facilitated a Liquidity Deposit Program to facilitate the payment. This instrument is at a floating rate and matches the dates of the two FCIC payments (April 1, 2024 and July 1, 2024). By regulation, this instrument must be recorded at amortized cost in the HTM portfolio. Therefore, as of April 1, 2024, we have already made the first payment of Ch$ 3.3 trillion and at the end of the second quarter we built liquidity deposits in the HTM portfolio for the second payment that we made on July 1, 2024. The rest of the HTM portfolio is made up of bonds from the Central Bank and the Chilean Treasury. At the end of June 2024, the HTM instruments have a fair market value of Ch$ 7,455,236 million. In June, the Ministry of Finance carried out an early exchange or redemption exercise of a closed list of existing/ current bonds. This was done with the purpose of managing the maturity of Chilean State debt in the coming years, offering new bonds to support liquidity and withdrawing non-referential bonds. During June 2024, the Bank participated in this exchange process for nominal amounts of Ch$4,320 billion. 26

The last rate hike by the Central Bank was in October 2022, when the monetary policy rate (MPR) reached 11.25%, closing the cycle of increases. This rate increase and the prolonged maintenance of this high level had a direct impact on our funding cost. The beginning of the rate cut cycle began at the end of July 2023 and after 5 successive cuts, the MPR ended 2023 at 8.25%. In 2024, the Central Bank has continued to cut the rate, reaching 5.75% in June. The Bank's total deposits decreased by 1.3% since December 31, 2023, explained by the 2.3% decrease since December 31, 2023 in demand deposits and a decrease in time deposits in recent months. Compared to March 31, 2024, total deposits decreased by 3.7%, with demand deposits falling by 2.1%, while time deposits also decreased by 5.0%, as customers responded to lower interest rates. Our clients' investments through mutual funds brokered by the Bank also grew in the quarter, reaching an increase of 7.9% QoQ and 21.6% since December 31, 2023. The decrease in the Central Bank's lines in the quarter is due to the first payment of the FCIC (facility granted by the Central Bank during the pandemic) on April 1, 2024. Bonds increased by 1.7% in the quarter and 5.6% since December 31, 2023. During 2024, the Bank has placed bonds for UF 4,222,000, CLP 101,050,000,000 and CHF 225,000,000, taking advantage of attractive opportunities in the different fixed-income markets at national and international level. The Bank's Liquidity Coverage Ratio (LCR), which measures the percentage of liquid assets over net cash outflows, as of June 30, 2024, was 187.1%, well above the minimum. As of the same date, the Bank's Net Stable Funding Ratio (NSFR), which measures the percentage of illiquid assets financed through stable funding sources, reached 102.3%, also well above the current legal minimum established for this ratio. 27

This represents a dividend per share of Ch$1.84393687 and a dividend yield of 3.8%. At the same ordinary Shareholders' Meeting, the Board of Directors was given the power to increase the percentage of dividend provision during 2024. The Board of Directors agreed to increase the dividend provision from the legal minimum of 30% to 60% of profits in 2024 until June 2024 and for the remaining months of the year. This is in accordance with its vision of the Bank's results expectations for the year. With this, the capital ratios from June 2024 reflect a dividend provision more in line with what we have historically paid. Therefore, total equity reached $4,296,490 million as of June 30, 2024, a decrease of 4.4% from December 2023, mainly due to the lower profit for the period, higher dividend provisions due to the increase in the provision mentioned in the previous paragraph and there is also a higher loss in the valuation accounts, related to the investment portfolio at fair value (available for sale). Compared to the close of March 2024, total equity increased by 0.1% mainly due to higher profits for the period but offset by the higher provision for dividend payments in the quarter. 28

Leverage: Core capital / Total regulatory assets, as calculated by the CMF. Our CET1 ratio remains solid at 10.6% and the total BIS ratio reached 17.4% as of June 30, 2024. Risk-weighted assets (RWA) increased 0.5% since December 31, 2023 and decreased 1.9% QoQ, explained by a decrease in credit risk-weighted assets. Additionally, in January 2024, the CMF announced the Pillar II charges for six banks in the Chilean system, and we highlight that, on this occasion, they did not assign a Pillar II charge to the Bank. At the same time, core capital decreased by 3.9% from December 31, 2023 and increased by 0.4% QoQ mainly due to the increase in the dividend provision described above and offset by higher profit in the quarter. The Bank's ROAE was 20.7% in 2Q24 compared to 11.2% in 1Q24, due to the higher result in the quarter as a result of the lower funding cost and higher income from the readjustments of the UF variation. With this, the ROAE for the six months accumulated to June 30, 2024 reached 15.8%, above the 2023 ROAE of 11.9%. 29

Interest expense divided by the sum of interest-bearing liabilities and demand deposits. 4. Net interest income divided by average earning assets. 5. Inflation measured as the variation of the UF in the period. Net interest and readjustment income (NII) as of June 30, 2024 increased by 54.5% compared to the same period in 2023. This increase in NII was mainly due to higher interest income due to the effect of the lower monetary policy rate on our funding cost, which fell from 7.1% to 5.0% in 6M24. This is partially offset by lower readjustment income. 30

Net income from readjustments had a variation of (36.9%) in 6M24 compared to the same period in 2023, given that the UF variation reached 2.1% in 6M24 compared to 2.8% in the same period in 2023. The UF GAP in 6M24 is larger than in 6M23, in line with a more stable UF variation vs an expectation of lower inflation in 6M23. The Bank has a shorter duration of interest-bearing liabilities than interest-bearing assets, so our liabilities recognize the change in rates more quickly than our assets. Following the rapid hike in the MPR that began in mid-2021 and continued through 2022, the Central Bank began cutting the MPR in July 2023 from 11.25%, with five successive cuts to reach 8.25% in December 2023 and then further cuts in 6M24 to end the period at 5.75%. This has led to a rapid recovery in net interest income, increasing 125.0% in 6M24 compared to 6M23. In 2Q24, total net interest and readjustment income increased 26.4% compared to 1Q24 and 80.2% compared to 2Q23. This is mainly due to higher interest income in 2Q24 compared to 1Q24 and 2Q23, which increased 17.1% QoQ and 192.2% compared to 2Q23 due to a lower average MPR in the quarter of 6.3% compared to 7.6% in 1Q24 and 11.3% in 2Q23. Our time deposits represent 33.6% of our funding at the end of June, and in general these deposits take the new rate between 30 and 60 days. On the other hand, the variation in inflation measured by the variation in the UF was 1.3% in 2Q24, higher than the 0.8% in 1Q24 and the 1.4% in 2Q23, explaining the 81.8% increase in net income from readjustments in 2Q24 compared to 1Q24 and (27.4%) compared to 2Q23. It is important to mention the first payment of the FCIC, a line of credit granted by the Central Bank during the pandemic, which was made on April 1. This generated a 4.8% decrease in interest-generating assets in the last quarter. With these dynamics of funding costs, inflation and decrease in interest-generating assets in the last quarter, the NIM increased from 2.1% in 6M23 to 3.1% in 6M24 and from 2.0% in 2Q23 and 2.7% in 1Q24 to 3.6% in 2Q24. The MPR ended the quarter at 5.75% and we estimate that the Central Bank could cut the rate in the second half to 5.25% with a UF variation of around 4% annually. With this scenario, we estimate that our NIM for the year 2024 will follow the recovery path to reach levels between 3.3% and 3.5% for the full year. 31

During the Covid-19 pandemic, asset quality benefited from state aid and pension fund withdrawals, which led to a positive evolution of assets during that period, and then began to normalize in line with the economy and the drainage of excess liquidity from households. Currently, the behavior of our clients is reflecting the state of the economy and the labor market, where non-performing loans (NPL) are slightly higher than usual, with the non- performing loan ratio (NPL) increasing from 2.1% in 2Q23 to 2.5% in 1Q24 and 2.7% in 2Q24. The impaired loan ratio increased from 5.4% in 2Q23 to 5.8% in 1Q24 and 6.2% in 2Q24. Finally, the expected loss ratio (credit risk provisions divided by total loans) has increased slightly, from 2.8% in 2Q23 to 2.9% in 1Q24 and to 2.9% in 2Q24 due to higher provisions established in recent periods. Net credit loss expense totaled $257,275 million YTD, an increase of 11.1% compared to the same period in 2023 and the cost of credit increases from 1.18% as of June 30, 2023 to 1.25% as of June 30, 2024. 32

In the quarter, net credit loss expense decreased by 1.0% compared to 1Q24, which is explained by a higher recovery of written-off loans, largely offset by an increase in provisions established for credit risk for banks and loans and accounts receivable from clients, which grew by 2.7% in the quarter. Therefore, the cost of credit remained stable at 1.25% in the quarter. The non-performing loan coverage ratio (which includes voluntary provisions of Ch$299 billion) decreased from 165.0% in 2Q23 to 142.4% in 1Q24 and 137.9% in 2Q24. This decrease in coverage is due to the increase in non- performing loans in the commercial and mortgage portfolios and also a higher weight of the mortgage portfolio in total loans, which require less coverage due to the associated collateral. We estimate that the evolution of portfolio quality in the coming quarters will follow the trend of the economy in 2024.

The increase is mainly related to household liquidity levels that have already returned to pre-pandemic levels coupled with a weaker economy. However, provisioning expense on consumer loans decreased 1.3% in 2Q24 compared to 1Q24, in line with a less dynamic portfolio in the quarter and a slight increase in recoveries in the quarter. The consumer NPL increased from 1.8% in June 2023 to 2.3% in March 2024 where it remained stable at 2.4% in June 2024 and the consumer impaired ratio increased from 4.2% in June 2023 to 4.9% in December 2023 where it has remained at these levels in March 2024 and June 2024, indicating a more normalized asset quality of the consumer portfolio. With this, the non-performing loan coverage of consumer loans is at 354.4% in June 2024. Commercial loan provision expenses increased by 19.0% in 6M24 compared to 6M23, and by 84.0% QoQ. The increase in provisions in the quarter is related to the economic cycle and an increase in provisions for non- performing companies (assessed on an individual and group basis). The non-performing loan ratio of the commercial portfolio increased from 2.9% in June 2023 to 3.5% in March 2024 and to 3.8% in June 2024 with the non-performing loan coverage ratio of this portfolio decreasing from 149.5% in June 2023 to 124.2% in March 2024 and 122.7% in June 2024. On the other hand, the impaired ratio of the commercial portfolio increased from 7.6% in June 2023 to 7.7% in March 2024 and to 8.6% in June 2024. Overall, the deterioration of the commercial portfolio is explained by particular names in the agriculture and real estate industries. However, it is important to mention that the commercial portfolio decreased by 5.5% in the quarter, mainly in loans to large companies and an increase in recoveries of commercial loans of 17.4% in the quarter. Mortgage loan provisioning expenses decreased by 11.0% in 6M24 compared to the same period in 2023 and 84.1% QoQ. The NPL ratio in June 2023 was 1.4%, then worsened to 1.5% in March 2024 and 1.6% in June 2024. 33

The mortgage impaired ratio increased from 3.4% in June 2023 to 4.0% in March 2023 and 4.3% in June 2024. The mortgage NPL coverage ratio increased from 66.1% in June 2023 and 70.9% in March 2024 to 69.0% in June 2024. It is important to remember that this portfolio has the property as collateral and currently has an LTV below 60%. For more information on credit risk and asset quality, see Section 6: Risk. Fees increase 6.5% QoQ, due to a larger customer base and product usage Net fees increased 6.5% QoQ due to the increase in clients and greater use of products such as mutual funds, cards, and current accounts. With this, the recurrence ratio (total net fees divided by total expenses) is 55.0% in 2Q24, demonstrating that more than half of the Bank's expenses are financed by fees generated by our clients. In the first half of 2024, fees decreased by 1.4% compared to the same period in 2023, mainly due to lower card fees due to the impact of interchange fee regulation. However, fees for our other core products continue to trend well. Fees per product: Financial accounting information The evolution of fees by product was as follows: YTD Var. % Quarterly Var. % Ch$ million Jun-24 Jun-23 Jun-24/ Jun-23 2Q24 1Q24 2Q23 2Q24/2Q23 2Q24/1Q24 Cards 60,613 63,035 (3.8%) 32,101 28,512 29,148 10.1% 12.6% Mutual Fund Brokerage 36,191 28,954 25.0% 18,447 17,744 14,650 25.9% 4.0% Insurance brokerage 31,473 31,858 (1.2%) 15,105 16,368 16,309 (7.4%) (7.7%) Guarantee 17,845 17,755 0.5% 9,940 7,905 8,453 17.6% 25.7% Collections 31,664 30,804 2.8% 15,870 15,794 14,638 8.4% 0.5% Current accounts 35,222 29,090 21.1% 18,052 17,170 14,923 21.0% 5.1% Getnet 29,886 21,172 41.2% 15,541 14,345 10,956 41.8% 8.3% Prepayment of credits 7,809 6,051 29.1% 4,372 3,437 2,703 61.7% 27.2% Others 11,319 37,138 (69.5%) 5,680 5,639 24,140 (76.5%) 0.7% Total commissions 262,022 265,857 (1.4%) 135,108 126,914 135,920 (0.6%) 6.5% Credit and debit card fees decreased 3.8% in 6M24 compared to the same period in 2023 due to the impact of the regulatory change in the interchange rates that began in October 2023. Card fees increased 12.6% QoQ, due to increased use of our cards and a slight decrease in associated costs. Mutual fund brokerage fees increased by 25.0% in 6M24 compared to the same period in 2023, by 25.9% compared to 2Q23 and by 4.0% QoQ. This is explained by the transfer of liquidity and time deposits from our clients to mutual funds as interest rates have dropped and clients are taking this type of investment through digital platforms. Insurance brokerage commissions decreased 1.2% in 6M24 compared to the same period in 2023 due to a decrease in personal insurance, partially offset by higher non-credit insurance commissions from companies. In 2Q24, insurance brokerage commissions decreased 7.4% compared to 2Q23 and 7.7% compared to 1Q24 due to 34

lower non-credit insurance commissions in the quarter for personal insurance, such as auto insurance, and lower commissions from insurance related to consumer loans. Collection fees increased by 2.8% in 6M24 compared to the same period of the year mainly due to higher collections from credit-related debts. In 2Q24, collection fees increased by 8.4% compared to 2Q23 and by 0.5% compared to 1Q24 due to higher collections from credit-related debts and foreign payment orders. Guarantee fees increased by 0.5% in 6M24 compared to the same period of the year and grew by 17.6% in 2Q24 compared to 2Q23 and by 25.7% compared to 1Q24 due to higher fees related to guarantee vouchers. Current account fees increased by 21.1% in 6M24 compared to the same period in 2023, while in 2Q24 they increased by 5.1% QoQ and by 21.0% compared to 2Q23. Growth in account openings continued to grow strongly during the quarter. With this, the bank's market share in total current accounts as of April 2024 is 24.1%. In addition, this includes a strong increase in customer demand for US dollar current accounts as customers can digitally open this type of account through the Santander Life platform in a few simple steps. We have opened 146,280 accounts in the last 12 months (as of April 2024) to reach a total of 400,498 dollar current accounts, reaching a total market share of 39.8%. Getnet, our acquiring business, showed an increase of 41.2% YoY and 8.3% QoQ as Getnet gains more customers and a greater number of transactions. At the end of the period, Getnet has more than 177 thousand points of sale in operation with a strong demand from SME clients and expansion towards larger clients with Host to Host solutions. Prepaid loan fees increased 29.1% in 6M24 compared to the same period in 2023 and increased 27.2% QoQ and 61.7% compared to 2Q23 mainly due to higher prepayments of commercial loans and consumer loans, in an environment where interest rates have fallen over the last year. The last item, others, considers commissions received and paid for other services, particularly from our subsidiaries. Net financial results decreased by 33.2% in 6M24 due to valuations of derivative contracts.

Net financial results recorded a gain of $108,381 million in 6M24, a decrease of 33.2% compared to 6M23 mainly due to a strong gain in the first quarter of 2023 from our trading of financial assets and liabilities portfolio (derivative contracts) that was not repeated in 2024 and offset by higher gains from foreign currency hedging. In 2Q24, net financial results decreased by 32.3% compared to 2Q23 due to a lower gain on foreign currency exchanges, adjustments and hedging and a higher loss on the valuation of derivative contracts. Compared to 1Q24, net financial results increased by 13.1%, mainly due to lower losses on the derecognition of instruments from our available-for-sale portfolio and offset by a higher loss on the valuation of derivatives and a lower gain on foreign currency exchanges, adjustments and hedging. For a better understanding of these lines, they are presented by business area in the following table: Financial results, net by business: Non-accounting financial information YTD Var % Quarterly Var % Ch$ million Jun-24 Jun-23 Jun-24/ Jun-23 2Q24 1Q24 2Q23 2Q24/2Q23 2Q24/1Q24 Client 130,592 128,478 1.6% 65,873 64,719 56,478 16.6% 1.8% Non client1 (22,210) 33,860 (165.6%) (8,358) (13,852) 28,489 (129.3%) (39.7%) Total net financial transactions 108,382 162,338 (33.2%) 57,515 50,867 84,967 (32.3%) 13.1% 1. Non-client income. These results include interest and mark-to-market effect from the Bank's trading portfolio, realized gains from the available-for-sale portfolio and other results of the Finance Division. Revenue from client treasury services reached a profit of $130,592 million in 6M24, an increase of 1.6% compared to the same period of the previous year, and an increase of 16.6% compared to 2Q23 and 1.8% compared to 1Q24. These results reflect the demand from clients for treasury products such as spot currency purchases, forward contracts and derivatives due to the high volatility of the market and the high level of the monetary policy rate. Non-client treasury totaled a loss of Ch$22,210 million in 6M24 compared to a gain of Ch$33,860 million in the same period in the previous quarter and a loss of Ch$8,358 million in the quarter, a decrease of 39.7% from 1Q24. This result is due to a loss from the liabilities management of our Financial Division explained by bond repurchases among others and negative results in the inefficiency of hedges of the portfolio managed by our team. This was offset by higher results from the liquidity portfolio and portfolio sales in the quarter. Core support expenses increase 4.2% in 6M24 in line with guidance Core support expenses (salaries, administration and amortization) grew 4.2% in 6M24 compared to 6M23 and 4.0% in 2Q24 compared to 2Q23 and 4.7% compared to 1Q24, in line with the growth of the inflation, as we mentioned in our previous guidance. Total operating expenses (which includes other expenses) increased 15.2% in 6M24 compared to the same period in 2023 driven by higher other operating expenses, related to a provision for the restructuring of our branch network and the transformation to Work/Café and also the progress in Digital Banking. The Bank's efficiency ratio reached 42.1% as of June 30, 2024, better than the 45.4% of the same period last year, with a quarterly efficiency ratio of 37.6%, explained by the recovery of revenues in the quarter. On the other hand, the cost to assets ratio increased to 1.4% in 6M24 vs. 1.3% in the same period of the previous year. 36

Productivity also continues to improve, with volumes per branch (loans plus deposits) up 10.2% YoY and volumes per employee up 6.7% YoY. This increase in productivity reflects the strength of our digital channels and a higher level of automation across the different cost centers. During 2024, the Bank is focused on advancing the execution of its US$450 million investment plan for the years 2023-2026, with a focus on technology initiatives and branch renovations.

Personnel expenses decreased by 8.5% in 6M24 compared to the same period in 2023 and by 10.3% in 2Q24 compared to 2Q23 due to a lower number of employees, which fell by 3.0% in the same period, which was partly offset by the adjustment of salaries in line with inflation. In 2Q24, personnel expenses increased by 12.3% 37

compared to 1Q24, mainly due to a seasonal effect in the first quarter of the year related to the staff vacation season and its respective provision. Administrative expenses increased 23.8% in 6M24 compared to the same period in 2023 and 28.7% in 2Q24 compared to 2Q23. In the same period, the value of the UF has increased 4.1% due to higher expenses related to leases and other long-term contracts and services and the exchange rate has depreciated 17.7% affecting technology-related services contracted in foreign currency. Compared to 1Q24, administrative expenses increased 0.5% mainly due to higher data processing and advertising expenses, offset by lower expenses related to leases and maintenance of fixed assets. Amortization expenses increased 0.3% in 6M24 compared to the same period in 2023 due to higher amortization of internally generated software and higher depreciation of equipment. Amortization expenses decreased slightly by 0.1% in 2Q24 compared to 2Q23 and by 3.8% compared to 1Q24 due to lower amortization of intangible assets partly offset by higher depreciation of fixed assets. Other operating expenses increased 652.4% in 6M24 compared to the same period in 2023, and decreased 60.3% QoQ. The increase corresponds to a one-off provision for restructuring plans in 1Q24 of approximately $17,000 million due to the progress in our branch network transformation and the progress towards digital banking, which implies a movement of operational functions to administrative functions. Operating expenses increased from $695 million in 2Q23 to $15,952 million in 2Q24 considering a low comparative base where in 2023 we benefited from lower expenses for operational risk event insurance premiums, which are now at normalized levels.

Income tax expense in 6M24 totaled $94,779 million, an increase of 286.5% compared to the same period in 2023 due to higher pre-tax profit and a lower effect of the monetary correction of taxable equity. For tax purposes, our equity must be readjusted by inflation, therefore, when inflation is high, the effective tax rate tends to be lower. As of June 2024, the effective rate was 21.6%. 38

In 2Q24, tax expenses increased 66.9% compared to the previous quarter due to the growth in pre-tax profit. Additionally, in 2Q24, there was the payment of the semi-annual coupon of our AT1 bond in April, which generates a tax benefit, which slightly reduces the effective rate to reach 21.2%.

Section 6: Risks Risk management in 2Q24 has focused on strengthening our risk structure in the face of low economic activity and labor market conditions. Credit risk Estimated expected loss: The estimation of provisions is based on expected loss models, in line with Chapter B1 of the Compendium of Accounting Standards of the CMF. 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 a simplified manner, provisions for most loans are determined with 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. • 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 41

borrower who is more than 90 days past due on 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. Portfolio Debtor's category Probability of Default (%) Severity (%) Expected loss (%) Normal porfolio A1 0.04 90.0 0.03600 A2 0.10 82.5 0.08250 A3 0.25 87.5 0.21875 A4 2.00 87.5 1.75000 A 5 4.75 90.0 4.27500 A6 10.00 90.0 9.00000 Substandard portoflio B1 15.00 92.5 13.87500 B2 22.00 92.5 20.35000 B3 33.00 97.5 32.17500 B4 45.00 97.5 43.87500 In order to calculate the provisions to cover a debtor classified as in default, first, an expected loss rate is determined by calculating the amounts recoverable through collateral and deducting the present value of recoveries obtained through collection services after related expenses. 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 Until 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 CMF accounting compendium for banks (Compendio Normas Contables Banco or CNC). 42

Provisions for group evaluations 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 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 for commercial and residential mortgage loans, the Bank must establish minimum provisions in accordance with the standard method established by the CMF 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. 43

Credit quality of debtors At the end of June 2024, the NPL rate continues to increase, reaching 2.7% as of June 30, 2024. The coverage ratio, including additional provisions, reached 137.9% as of June 30, 2024, with the expected loss ratio (credit loss provisions divided by total loans) increasing slightly to 2.9%. The impaired ratio closed at 6.2%, up from 5.6% as of December 31, 2023. The impaired ratio includes NPLs in addition to restructured loans, being an indicator with a broader view than NPL. The commercial portfolio has increased in NPL and impaired over the last 12 months, while the mortgage portfolio has been slightly more stressed in the last half year, both due to the economic cycle and labor market conditions. However, it is important to remember that mortgage holders generally have a property as collateral.

Their measurement and control is the responsibility of the Market Risk Management, which is part of the Risk Division. The limits are approved by the various committees in charge, a responsibility that lies mainly 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 Financial Division, have the following functions, which are supervised and controlled by the ALCO and Risk Management: • Optimizing the cost of liabilities, seeking the most efficient financing strategies, including the issuance of bonds and bank lines. • Manage short- and long-term regulatory liquidity limits. • Inflation risk management and exposure. • Manage local and foreign currency exchange rate risk. • Capital adequacy and requirements Liquidity risk The Financial Management area manages liquidity risk by using a portfolio of liquid assets to ensure that the Bank always maintains sufficient liquidity to cover short-term fluctuations and long-term financing, complying with internal regulatory liquidity requirements. The Financial Management Department 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 derived from future business. Based on this information, the area maintains a portfolio of short-term liquid assets, composed mainly of liquid investments, loans and advances to other banks, to ensure that the Bank has sufficient liquidity. The liquidity needs of the business units are covered by short- term transfers from Financial Management to cover short-term fluctuations and long-term financing to meet all structural liquidity needs. 47

The Bank monitors its liquidity position on a daily basis, determining the future flows of its expenses and income. Additionally, stress tests are carried out at the end of each month, for which a variety of scenarios are used that cover both normal market conditions and market fluctuation 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 break down the liquidity position of the Bank and its subsidiaries, including exceptions and corrective measures adopted, which are periodically submitted to the ALCO for review. The Bank obtains demand and fixed-time deposits from retail, EIB and Corporate banking. The Finance Department obtains funding from correspondent banks, debt instruments, commercial paper and wholesale time deposits. Although most obligations to 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 and therefore the Bank actively manages this risk by continuously monitoring market trends and managing pricing. High quality liquid assets High-quality liquid assets (HCA) are an essential component in liquidity risk management. They consist of balance sheet assets, composed mainly of financial investments that are not collateralized, 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 June 30, 2024, the Bank's ALAC amounted to $8,533,887 million and corresponded mainly to Level 1 liquid assets, composed mainly of bonds of the Republic of Chile, the Central Bank of Chile and the United States Treasury. Liquid Assets (Consolidated Ch$ million) Tier 2: Fixed income, Tier 1: Available, 1,569,775 Tier 1: Fixed income, 6,958,735 5,377 In terms of liquidity, the main metrics managed by the Bank's Finance Division are the following: 1. Liquidity Coverage Ratio (LCL). 2. Net stable financing ratio (NSFR). 48

LCR 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 in relation to their activities. As of June 30, 2024, this indicator for Banco Santander Chile was 187.1% above the minimum. This is a reflection of the conservative liquidity requirements established by the board of directors through the ALCO committee.

Interest rate risk: banking book For the financial management portfolio (bank book), the Bank has more liabilities than assets exposed to short- term rates, and this creates mismatches when rate adjustments occur. To manage this risk, Banco Santander performs a sensitivity analysis with respect to local and foreign currencies. Through simulations, limits are set in relation to the maximum loss that rate movements may have on the capital and net financial income budgeted for the year.

Due to the rules established by the Assets and Liabilities Committee (ALCO), the Bank must not have significant exposure to foreign currencies; therefore, all exchange rate risk is included in the trading portfolio and is measured and controlled with Value at Risk (VaR) limits. 50

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.

In general, the Bank has more assets than liabilities in UF and, therefore, moderate increases in inflation have a positive effect on indexation income, while a fall 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.

In the same vein, digital customers grew by 7.7% YoY, due to the success of digital initiatives. 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 allows digital onboarding in a safe, fast and easy-to-use way, offering our Life and Más Lucas accounts for the mass segment and the Life SME account and payment services through Getnet for entrepreneurs and medium and small businesses. These initiatives not only encourage our clients to become increasingly digital, but are also achieving increased financial inclusion in these segments through an initial approach through transactional services, with the potential to extend the offer 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 into Work/Café, evaluating the needs of our clients in different areas and providing branches that not only meet their financial needs, but also provide them with a pleasant environment to approach us. 60

Digital Clients: As a result of these efforts, the Bank's market share in current accounts remains strong. According to the latest publicly available information, which is as of April 2024, our market share reaches 24.1% in current accounts, which includes products such as Santander Life and PYME Life. These figures do not include our Más Lucas checking account. In addition, due to the volatility in the exchange rate, we have seen increasing customer demand for dollar checking accounts. As of April 2024, we have a market share of 39.8% and we have opened 146 thousand dollar checking accounts in the last twelve months, thanks to the ease of opening these accounts online and a strong increase in customer demand for this type of account. Furthermore, digital clients continue to grow, surpassing 2 million digital clients. Our digital clients represent 86% of our active clients and the majority are current account holders, and the products with the greatest traction are deposits, credit cards, investment funds and general insurance. +2 million digital customers DIGITAL CUSTOMERS 1,076,937 2,130,718 M ar -1 9 Ju n- 19 Se pt -1 9 De c- 19 M ar -2 0 Ju n- 20 Se pt -2 0 De c- 20 M ar -2 1 Ju n- 21 Se pt -2 1 De c- 21 M ar -2 2 Ju n- 22 Se pt -2 2 De c- 22 M ar -2 3 Ju n- 23 Se pt -2 3 De c- 23 M ar -2 4 Ju n- 24 * Digital customers are those who access their account online or through the App at least once a month. 61

Más Lucas is the first 100% digital savings and checking account for the mass market. This product does not charge maintenance or transaction fees and is also remunerated monthly according to the balance maintained. In this way, the Bank aims to provide better 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 177 thousand clients and in recent months has maintained an average of 15 thousand accounts opened per month. 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 contact with a bank, offering them digital products with the ease of paying with a debit card and online transfers.

Additionally, the sale of mPOS, which are more compact devices, continues to grow, where we have more than 1,200 mPOS sold. In addition, e-commerce also attracts merchants, with more than 6,700 businesses using Getnet for their online sales to date, reaching $197 billion in sales in the last 12 months.

Other initiatives launched recently Apart from the Más Lucas Joven account, we have also launched the following: • Complementary health insurance with UC Christus medical centers, where they implemented a revolutionary medical care model for Chile. Clients have access to a primary care physician, who is available for both in-person and online consultations, and who refers patients to the appropriate specialists, maintaining a holistic view of the patient, encouraging prevention and reducing waiting times for specialties. • Autocompara: A digital platform to compare car insurance in a transparent and efficient way, allowing people to make an informed decision before purchasing insurance. In June 2024, we opened this platform to non-customers as well, being one of the few platforms available in Chile with this service. • Currency transfers to 28 countries online or with reception in a branch. These transfers are safer and faster than swift transfers and are free for our clients. We continue to grow in Work/Café branches As of June 2024, we have a total of 96 Work/Cafés, which consider different types such as Investment Work/Cafés, StartUps and regular ones. We have closed 16 branches in the last 12 months, including Select branches, aimed at higher-income clients, and traditional branches. In total, we have 244 branches, 6.2% less than last year. In 4Q22, we launched Work/Café StartUp, an initiative that aims to offer a comprehensive solution to all the needs of entrepreneurs, and in particular to increase banking penetration, carry out pilot programs with the Bank and even offer financing. It is aimed at companies that have three main characteristics: first, that they are starting activities and showing accelerated growth; second, that technology is part of the value proposition; and third, that the proposals are scalable to a real problem. Then, in 1Q23, we launched Work/Café Expresso, our new transaction centers with cashier or self-service services, service desk, card printing machines, and lockers for product delivery, all in Work/Café format, where our customers can carry out their transactions in an efficient and secure environment, providing a better customer experience. These high-tech branches provide greater efficiencies with our cash management, allowing us to continue consolidating our branch network. Since its launch, Work/Café Expresso's NPS is 74%, which has helped improve the bank's overall opinion. And finally, in 4Q23 we launched Work/Café Inversiones, a new space open to the community aimed at helping people improve their financial well-being. Clients and potential clients will be able to access specialized advice, talks and workshops on different 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 specific initiatives such as the opening of this new space, the Bank continues to make clear progress in its purpose of helping people progress. 64

With all of the above, we continue to find efficiencies in our branch network, with over 30% of our branches cashless. Due to the strength of our digital channels, the Bank's productivity continues to grow, with volume per branch increasing 10.2% YoY and productivity per employee increasing 6.7% YoY.
