Section 1: Highlights Solid financial performance with a 31.5% ROAE1 in 2Q262 and a 40.0% increase in earnings for the quarter. In the second quarter of 2026, net income attributable to the Bank's owners totaled $383 billion ($2.00 per share and US$0.90 per ADR). Compared to the previous quarter (1Q26), net income attributable to the Bank's owners increased 40.0% QoQ3 and 40.4% compared to 2Q254, primarily due to higher net income from readjustments in a quarter characterized by higher inflation (2.5% vs. 0.3% in 1Q26 and 1.0% in 2Q25), in addition to lower loan loss provisions during the quarter. As a result, ROAE increased from 24.5% in 2Q25 and 23.0% in 1Q26 to 31.5% in 2Q26. As of June 30, 2026, net income attributable to the Bank's owners totaled $656 billion ($3.48 per share and US$1.51 per ADR). Compared to the same period of the previous year, net income increased by 19.2%, reaching a ROAE of 27.2% in 6M26 versus 25.1% in 6M255. This is mainly due to higher net interest income resulting from higher inflation in the readjustment income line, as the UF variation was 2.7% in 6M26 compared to 2.2% in 6M25. Higher results from financial transactions and lower operating expenses also contributed to this improvement. Furthermore, at the shareholders' meeting in April 2026, it was agreed to distribute 60% of the 2025 profits as dividends. This represents a dividend of $3.35 per share and a yield of 4.5%. The Bank maintains a solid CET1 ratio6 of 11.1% with a BIS ratio7 of 16.6% as of June 2026. Net interest and inflation-linked income increased 26.9% QoQ with a NIM8 of 4.7% in 2Q26. In 2Q26, total net interest and inflation-linked income increased by 26.9% compared to 1Q26, primarily due to a strong 441.2% increase in inflation-linked income in 2Q26. This was driven by the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account) inflation rate, which rose from 0.3% in 1Q26 to 2.5% in 2Q26, due to the inflationary shock from oil prices. As a result, the NIM for the quarter increased from 3.8% in 1Q26 to 4.7% in 2Q26. Net interest and inflation-linked income YTD to June 30, 2026, increased 7.4% YoY9, with net interest income growing 5.4% and net readjustment income growing 17.7%. As a result, the net interest margin (NIM) increased from 4.1% in 6M25 to 4.3% in 6M26. 4 1Net profit attributable to owners of the Bank annualized divided by the average equity attributable to equity holders. 2Second quarter of 2026. 3Quarter versus quarter. 4Second quarter of 2025. 5The six months ending on June 30, 2025. 6Common Equity Tier 1 under Chilean regulation. 7Basel ratio (Tier 1 + Tier 2) under Chilean regulation. 8NIM: Net interest margin.

Total deposits grew 4.5% in the quarter. In the quarter, total deposits increased 4.5% QoQ, with time deposits growing 7.0% QoQ and demand deposits increasing 1.4% QoQ, related to our customers' increased liquidity in recent months. Mutual funds, meanwhile, grew 3.1% QoQ. Overall, customer funds grew 4.0% QoQ. Compared to December 31, 2025, our clients' funds grew by 7.1%. Total bank deposits increased by 6.0%, driven by an 11.8% increase in time deposits. Furthermore, there is a noticeable increase in client interest in mutual funds, which have grown by 9.5% since June 30, 2025. Total loans grow 1.3% QoQ, driven by commercial and mortgage loans Total loans at amortized cost increased 1.2% YoY compared to December 31, 2025, and 1.3% QoQ, reflecting growth in commercial, mortgage, and auto loans during the quarter. This was partially offset by lower growth in credit cards and consumer installment loans. This quarter we began to see an incipient improvement in growth in commercial loans increasing by 1.5% since December 31, 2025, and 1.3% QoQ. This trend is explained, firstly, by the impact of the Chilean peso's appreciation against the US dollar since December 2025, and by greater demand for foreign trade loans in recent months. Secondly, it reflects a slight improvement in the growth of non-foreign trade loans. Mortgage lending increased by 1.4% since December 31, 2025, and by 2.0% QoQ, due to a better origination dynamic and higher inflation in the quarter. Additionally, with an improved economic environment and new measures to encourage home purchases, we expect a gradual recovery in mortgage demand in the coming periods. Best in Class in Efficiency10 with 30.8% in 2Q26. The Bank's efficiency ratio reached 30.8% in the quarter, an improvement over the 32.5% recorded in 1Q26. This improvement was driven by higher net readjustment income due to higher inflation during the quarter and lower credit risk expenses, coupled with effective cost control. For the first six months of 2026, the efficiency ratio reached 31.6%, an improvement on the 35.3% registered in 6M25. Customer base expansion continues, with total customers increasing 6.9% YoY. The strategy of strengthening digital products has led to continued growth in our customer base, reaching over 4.8 million customers, of which 2.7 million are active. The Bank's market share in current accounts remained 5 10Operating expenses including impairment and other operating expenses/ margin+commissions+ financial transactions and other net operating income.

strong, reaching 20.8% as of May 2026. Furthermore, increased use of digital platforms continued to drive fee income, with YoY growth of 10% in mutual fund brokerage and 26.6% in insurance brokerage. As a result, the recurrence ratio (total net fees divided by structural support expenses) increased from 61.9% YTD11 to June 2025 to 64.1% YTD to June 2026, demonstrating that almost two-thirds of the Bank's expenses are funded by customer-generated fees. 6 11 Year to date

Macroeconomic Environment During the second quarter of 2026, the Chilean economy operated in a still challenging external environment, marked by rising fuel prices due to the armed conflict in the Middle East. A brief improvement toward the end of the period was reversed in early July by renewed external tensions. Copper continued to act as the main external buffer for the economy, while the resurgence of geopolitical tensions amplified upward pressure on energy prices. Nevertheless, the economy remained exposed to the evolution of the global context and the volatility of international financial markets. Domestically, economic activity remained weak throughout the quarter. Domestic demand failed to consolidate a more dynamic trajectory, and private consumption faced a more restrictive outlook due to weak job creation and higher inflation that eroded real incomes. This was compounded by supply-side factors, such as the weakening fishing industry, which dragged down other sectors like manufacturing. At the same time, business confidence and economic expectations moderated compared to previous readings. In this context, the growth projection for 2026 was adjusted to 1.0% annually. The labor market remained fragile. The unemployment rate exceeded 9% in the March–May 2026 moving quarter, in a context where job creation remained limited and without clear signs of recovery. This employment performance, along with still-weak economic activity, continued to constrain the evolution of private consumption and the speed of the domestic recovery. In terms of prices, the quarter was marked by an inflationary surge primarily associated with the cost shock stemming from the conflict in the Middle East, although without significant signs of a second-round effect. The May CPI surprised on the downside with a monthly increase of 0.2%, while the June figure showed no change, which was nonetheless above market expectations and pushed annual inflation to 4.3%, from the previous 3.9%. Meanwhile, the June Monetary Policy Report (IPoM) reduced the projected growth range for 2026 to 1.0%-1.75% and raised expected inflation to 4.2%, in a scenario where the most likely path for the Monetary Policy Rate (TPM) remained at 4.5% for most of the projection horizon.

Financial market development As part of its market development agenda and refinement of the Basel III framework, the CMF published on April 13 the final regulations aimed at reducing regulatory friction in the repo and securitization markets. Among the main changes, the prudential treatment of repo transactions is simplified, the concept of significant risk transfer in securitizations is incorporated, the 1.250% weighting for retained instruments is eliminated, and adjustments are introduced to facilitate the registration of self-securitizations and the issuance of mortgage-backed securities. These measures should contribute to greater liquidity in the fixed-income market, strengthen the liquidity management of the banking system, and support a deeper and more competitive financial market. Then, on April 14, CMF President Catherine Tornel reinforced this agenda at the Capital Markets: Major Challenges 2026-2030 seminar, highlighting the institutional focus on market development. In that context, she announced progress in promoting the adoption of internal credit risk measurement models under Basel III, along with the creation of a specialized team for their validation. Finally, on July 3, the CMF held its second public consultation on the regulation updating the determination of Market Risk-Weighted Assets (MRWA), highlighting the following aspects: First, the duration method is incorporated for measuring overall interest rate risk, allowing for a more accurate reflection of variations in the economic value of positions in response to interest rate changes. Second, the current guidelines for excluding derivatives from interest rate risk estimation are refined, enabling the full offsetting of matched derivative positions even when they are not strictly identical. The CMF estimates that this will help reduce the system's MRWA by approximately 36%. 11

All these measures have the potential to contribute to the development of the financial system, although their final impact will depend on the depth to which the entities adopt the changes and on the evolution of the economic and financial cycle. Dividend Subsidy Law On May 20, 2025, Congress approved the Dividend Subsidy Law to facilitate access to homeownership and revitalize the real estate market. This initiative includes a subsidy of up to 60 basis points on mortgage interest rates. Furthermore, it is backed by a state guarantee from the Special Guarantee Fund (FOGAES) that covers up to 60% of the property value, which could further reduce the total interest rate by up to 100 basis points. The project aims to provide 50,000 subsidies, 10% of which are earmarked for first-time homebuyers valued up to 3,000 UF (Unidades de Fomento, a Chilean unit of account) and the remaining percentage for new homes valued up to 4,000 UF. To date, this program has been a significant factor in supporting the demand for mortgage loans. According to ABIF (Chilean Banking Association), as of June 19, 2026, 48,990 eligible applications had been received and commercially approved, a figure close to the 50,000-subsidy limit, and more than 26,948 mortgages had been processed. Pension Reform On January 29, 2025, Congress approved the pension reform after a lengthy process of considering various proposals. The main objective is to increase future and current pensions, taking into account the following changes. Pension contributions will increase by 7%, paid by employers, starting at 1% in August 2025 and gradually increasing over a period of 9 to 11 years. Of the total percentage, 6% will go to direct, deferred individual capitalization, and 1% to the new Social Security system, which will also include the current 1.5% allocated to Disability and Survivors' Insurance. These resources will allow for equal pensions for men and women in similar circumstances at the time of retirement. The reform also includes changes to the pension fund structure. The multi-fund system will be replaced by generational funds, and new administrators will be allowed to enter the system. A 10% share of the existing pension fund will be put out to tender every two years to increase competition. In addition, the reform proposes increasing the Guaranteed Universal Pension (PGU) to $250,000 pesos for the 90% of the most vulnerable population. More than a year after the law's enactment, the implementation of the pension reform continues to progress gradually according to the legal timeline. Significant milestones have been reached during 2026, such as the launch of the Single Contribution Collection System (SUCC), the commencement of pre-litigation collection by the General Treasury of the Republic, and the implementation of the new Social Security contributions. Furthermore, a new phase of increased employer contributions begins in August, while in September the Guaranteed Universal Pension (PGU) for individuals aged 75 and over will increase. While several operational measures have already been implemented, the final issuance of key regulations for the new individual capitalization system is still pending. Among these operational measures, mandates have already been awarded for the administration of the autonomous pension protection funds (FAPP), and the proposal for the Investment Regime for Generational Funds—currently open for public consultation—stands out. This 12

proposal will define the investment structure, risk limits, and benchmark portfolios of the funds that will replace the multi-funds starting in April 2027. Its final publication is one of the main regulatory milestones remaining for the reform. Beyond the details, it is commendable that the reform allows for a gradual recovery of pension savings levels. This is beneficial not only for financing future pensions but also for the capital market, insofar as a large part of this extra percentage is channeled under the current pension fund investment regime, even though the final impact will depend on the secondary regulations, which are still pending, and the investment rules of the new system. Interchange fees In February 2023, the Interchange Fee Limits Committee proposed new limits on the rates. These were approved at the end of April 2023, and a phased implementation was established. Card type Previous rate First cut (Oct-23) Current rate Second proposed cut (oct-24) (Suspended) Debit 0.6% 0.5% 0.35% Credit 1.48% 1.14% 0.80% Prepaid 1.04% 0.94% 0.80% In September 2024, just before the second rate reduction was to be implemented, the Committee decided to suspend the new phase of reductions, maintaining the existing limits, in order to assess the effects of the reductions already implemented on the functioning of the payments system. To this end, it was agreed to conduct an impact study to analyze market behavior and the foreseeable effects of a potential further rate reduction. Subsequently, and as recorded in the minutes of the Committee, the early termination of the contract with the external consultant in charge of the impact study was reported, due to the time elapsed and the lack of complete execution of the contract. To date, the future trajectory of interchange fees remains uncertain. The second rate cut remains suspended, and at the committee meeting on June 24, members evaluated and approved a new consultant to conduct the study. Consolidated debt In early June 2024, the law creating the Consolidated Debt Registry (REDEC) was passed. This registry consolidates information on outstanding loans granted to individuals. The registry will be public and free of charge, and will be managed by the Financial Market Commission (CMF). The legislation expands the scope of entities required to report, incorporating, in addition to banks and savings and credit cooperatives, mortgage loan administrators, compensation funds, credit card issuers regulated by the CMF, securitization companies, credit advisory entities regulated by the Fintec Law, and other entities that the CMF may determine through a General Regulation. Access to registry information will generally require the prior, express, and unequivocal consent of the debtor, granted for the assessment of their credit risk in a specific transaction and for a limited period, unless there is another legal basis for access under Law No. 19,628 or the information is anonymized. In July 2025, the CMF issued the REDEC operational framework, defining reporting obligations, applicable procedures, and information security and quality standards. 13

The regulations came into effect in April 2026, and since then the CMF has issued technical adjustments to the Information System Manual, resolved queries from reporting entities, and continued to incorporate new actors required to report. Regulatory priority has focused on stabilizing the system and ensuring the quality of reported information, a key element for proper credit risk assessment and the functioning of the financial market. Fintech and Open Finance Law The development of the Open Finance System (OFS) originated with the approval of the Fintec Law in 2023, which established the legal framework for the secure and consensual exchange of financial information among different actors in the system. In 2024, the CMF (Financial Market Commission) issued the specific regulations governing the OFS, defining the participation obligations for regulated financial entities and the conditions for the voluntary registration of new financial service providers. These regulations included an implementation timeline that set the system's entry into force within a two-year period, which raised concerns regarding operational feasibility, implementation costs, and the maturity of the proposed technical standards. During the last few months, the CMF issued three rules for public consultation aimed at adjusting the implementation schedule of the SFA, along with defining in greater detail the technological standards necessary for its implementation. The main recent milestone was the issuance of the final standard NCG No. 569, which contains the technical specifications for system interoperability and introduces a series of adjustments aimed at facilitating a gradual and secure implementation of the SFA. These include postponing the effective date until July 2027, incorporating a pilot period for controlled testing among participants, establishing a technological sandbox managed by the CMF, creating simplified participation mechanisms for smaller entities, and standardizing procedures to reduce operational friction. Despite these advances, key regulatory aspects remain to be defined, including the cost-sharing model between entities that provide information and those that consume it. In this context, the SFA remains a regulatory project under development, and its final design will be crucial in assessing its impact on competition, innovation, and compliance costs for financial institutions in Chile. In this context, in December 2025, the Central Bank authorized a local fintech company to operate a low-value payment clearinghouse, enabling potential future changes in the functioning of the payments market. Personal Data Protection Law In December 2024, a law was published modernizing the protection and processing of personal data in Chile, establishing a regulatory framework aligned with international standards such as those of the European Union. The legislation creates the Personal Data Protection Agency, the body responsible for overseeing compliance with the law, imposing sanctions, issuing guidelines, and promoting best practices in data processing. The law recognizes new rights for data subjects—access, rectification, erasure, objection, and portability—and establishes relevant obligations for organizations, such as implementing compliance programs, adopting security measures, managing incidents, and appointing a Data Protection Officer. The law is set to enter into force on December 1, 2026, and the first appointment to the Agency's Governing Board should have been made by Congress in June 2026. However, this appointment is still pending. 14

Draft Law on Reconstruction and Economic and Social Development The National Reconstruction and Economic and Social Development Bill is in its final stage of legislative processing. After being approved by the Senate with several modifications, the Chamber of Deputies is currently debating it in its third constitutional stage, placing the bill in the final stage of the legislative process. Among the most relevant measures is the tax agenda aimed at strengthening investment, improving competitiveness, and supporting economic recovery. Specifically, the bill includes a gradual reduction of the First Category Tax rate from 27% to 23%, one of the most significant tax modifications in recent years, along with the complete reintegration of the tax system. This measure is designed to simplify the tax structure, reduce the cost of capital, and provide greater incentives for private investment. It also incorporates a temporary VAT exemption for the sale of new homes, an initiative that seeks to accelerate the absorption of the large available housing stock, stimulate the real estate and construction sectors, and facilitate access to housing. Additionally, the bill includes incentives for formal employment, investment benefits, property tax exemptions for senior citizens, and the creation of a special fund for the reconstruction of areas affected by wildfires. The initiative also incorporates other relevant financial and regulatory modifications, some of which have been the subject of extensive debate during its legislative process. Guarantee management as credit risk mitigators In July 2026, the Financial Market Commission published Circular No. 2,373, which establishes a new prudential framework for the management, valuation, and recognition of collateral used by banks as credit risk mitigators. The regulation incorporates Chapter 21-10 of the Updated Compilation of Regulations and reinforces the responsibility of the Board of Directors and senior management regarding the policies, controls, and procedures applicable throughout the collateral lifecycle. The circular requires that guarantees be legally valid, enforceable, properly documented, and prudently valued, taking into account their liquidity, execution costs and timeframes, asset volatility, and market conditions. It also establishes obligations for periodic revaluation, traceability, safekeeping, independent monitoring, and recording of amounts actually recovered. Guarantees that do not meet these conditions may be withdrawn to reduce credit exposure, leading to higher provisions and potentially greater capital consumption. Most of the provisions will come into effect on January 1, 2028. However, the changes related to the assessment of the quality of guarantee management by the CMF are effective immediately, so banks must begin adapting their policies, valuation methodologies, information systems, controls and execution processes in advance. Regulation and supervision In Chile, only banks can maintain current accounts for their clients, conduct foreign trade operations, and, along 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 primarily subject to the General Banking Law and, secondarily, to the extent that it is not incompatible with this law, to the provisions of the Chilean Corporations Law governing corporations, except for certain provisions that expressly exclude them.

Main advances of the strategy Digital Bank with Work/Cafes The Bank's strategy is based on cutting-edge technology, along with processes and products designed with a customer focus. The Bank is building robust capabilities in digital channels, enabling secure, agile, and user- friendly onboarding. Through this approach, it offers digital accounts for the mass market, specific solutions for SMEs, and payment services via Getnet for entrepreneurs and small and medium-sized businesses. These initiatives not only drive digital adoption among our clients but also promote greater financial inclusion in these segments. The Bank facilitates an initial approach through transactional services, with the potential to expand its offerings to include other products and financing options, such as credit cards and loans. In parallel, the transformation of its branch network to the Work/Café model is a key pillar of its strategy. This approach considers the needs of customers in each region, offering spaces that not only meet their financial requirements but also provide a welcoming, comfortable, and friendly environment for interacting with the Bank. Customers: Customers: 2023 2024 2025 June 2026 Total customers 4,052,314 4,311,488 4,608,182 4,825,551 Loyal customers 850,905 1,305,953 1,378,876 1,348,309 Active customers 2,398,741 2,556,462 2,693,441 2,693,108 Digital customers 2,113,128 2,238,774 2,291,971 2,253,290 Total customers increased by 6.9% YoY, while active customers grew by 1.3% YoY.

According to the latest publicly available information from the CMF as of May 2026, the Bank holds a 20.8% share of all current accounts for both individuals and businesses, a figure that does not include demand deposit accounts. Meanwhile, demand for dollar current accounts continues to show positive growth. As of May 2026, the market share reached 36.4%, driven by the ease of online account opening and sustained customer demand for this type of product. In the SME segment, the number of accounts continues to grow strongly, supported by initiatives such as Getnet, the acquiring business, and offering 100% digital current accounts. These accounts include access to a debit card 19

and Office Banking, the transactional platform for businesses. This comprehensive approach allows the company to meet its clients' transactional needs and support them in the development and growth of their businesses.

Likewise, deepening relationships with this segment and the convenience of digital channels contributed to a 3.3% YoY growth in the number of SME clients. Additionally, for those clients who meet the eligibility criteria, we offer credit cards and various financing options. Expansion in payment services Getnet's operations in Chile have solidified its position as a leading player in the acquiring market, distinguished by strong growth and increasing market share. As of June 2026, it has over 287,000 operational POS terminals and more than 229,000 affiliated merchants, along with a payment solutions ecosystem that blends physical and digital presence, positioning it as one of the most dynamic networks in the country. This development has also been reflected in solid financial results and sustained expansion in transactions and processed volumes. Getnet's value proposition has evolved into an omnichannel model, integrating solutions for in-person payments, e-commerce, and value-added services, tailored to different types of businesses, from entrepreneurs to larger companies. In particular, its offering for SMEs has been key to driving the digitization of payments, while the development of more sophisticated solutions—such as integrations and customized services—has allowed it to expand its reach to corporate clients. Furthermore, Smart POS devices have expanded their functionality beyond simply accepting payments, becoming true service platforms for businesses. Today, they allow, for example, bill payments, mobile top-ups, and other transactions, contributing to increased customer traffic and generating new business opportunities for partner merchants. This is further complemented by the sustained growth of the e-commerce channel, which has become a key pillar of Getnet's offering, supporting the digitalization of commerce in Chile. 20

More than 40% of our branches operate on a cashless basis. As of June 2026, the Bank has a total of 224 branches, 123 of which operate under the traditional format. Since launching the Work/Café model in 2016, 91 branches have opened throughout Chile. This format includes different variations, such as Work/Café Investments, StartUp, Expresso, and Standard. Furthermore, the Bank is working on renovating traditional branches to adopt the Work/Café look and feel, a process that has already been completed at 18 branches. Within this network, the Work/Café Expresso locations stand out. Designed as transactional centers, they integrate teller and self-service options, service desks, card printing machines, and lockers for product delivery. All of this is offered in a modern and efficient environment, allowing customers to conduct their transactions quickly and securely, significantly improving their experience. These branches, supported by advanced technology, also generate significant efficiencies in cash management, contributing to the optimization and consolidation of our network. In this context, efficiencies continue to be captured in the branch network, with more than 40% of them currently operating on a cashless basis. In line with the strategy, customers are more satisfied with digital channels As a result of all the efforts with digital channels, customers are showing greater satisfaction with these service channels.

Section 5: Segment information Segment information is based on the financial information presented to senior management and the Board of Directors. The Bank has aligned segment information consistently with the underlying information used internally for management reporting purposes and with that presented in other public documents of the Bank. Senior management has been determined to be primarily responsible for the Bank's operational decision- making. The Bank's operating segments reflect its organizational and management structures. Senior management reviews internal information on a segment basis to assess performance and allocate resources. As of March 31, 2026, the Bank revised the identification of its operating segments to reflect changes in its internal management structure and in how the Chief Operating Decision Maker (CODM) evaluates performance and allocates resources. Consequently, comparative information has been restated for consistency with the current period's presentation. Management believes this revised presentation provides more relevant information for users of the financial statements. In order to achieve the strategic objectives set by senior management and adapt to changing market conditions, the Bank periodically makes adjustments to its organization. These modifications, in turn, impact, to a greater or lesser extent, how the Bank is managed and administered. This disclosure provides information on how the Bank is managed as of June 30, 2026.

This trend was partially offset by slower growth in consumer loans, particularly credit cards, due to improved liquidity among our clients, as evidenced by the 4.0% increase in deposits in this segment compared to December 31, 2025, and a 4.3% QoQ increase. Net operating income for this segment increased 7.6% YoY and 42.2% QoQ, driven by a higher margin, though impacted by higher inflation of 2.5% during the period. Provisions also decreased by 23.9% in the quarter due to the reversal of a provision established in 1Q26 for a corporate client. However, provision expenses increased 3.2% YoY due to higher provisions in line with the evolution of asset quality, explained in more detail in Section 8: Risks. Wealth Management & Insurance (WM&I) Wealth Management & Insurance's loan portfolio grew 8.3% YoY and 2.9% QoQ, driven by higher general- purpose commercial and mortgage loans. Deposits increased 1.6% YoY and 5.2% QoQ, reflecting our clients' improved liquidity position during the quarter. Net operating income increased 20.4% YoY and 7.1% QoQ, primarily due to higher margins driven by growth in client loans and funds. Additionally, compared to 2025, net income in this segment is projected to increase due to higher fees generated by mutual funds and travel-related insurance. Corporate Investment Banking (CIB) CIB's loan portfolio grew by 2.1% YoY and 2.5% QoQ, reflecting improved performance compared to previous periods, particularly in the foreign trade portfolio during the last quarter. Deposits increased by 13.2% YoY and 4.7% QoQ, thanks to strong relationships with these clients and an improvement in their liquidity position. Net operating income increased 11.5% YoY but decreased 20.8% QoQ explained by stronger margin growth and results from financial transactions, associated with client demand for fixed-income market-making products, which peaked in 1Q26. This was offset by lower commission performance in the quarter due to lower M&A advisory services and the establishment of provisions in the quarter following a release in 1Q26. Payments 26

Payments had a weaker quarter with less transactional activity from customers due to increased market competition and therefore greater price pressure. Digital Consumer Bank Digital Consumer Bank's loan portfolio grew 4.9% YoY and 1.8% QoQ. Net operating income increased 25.9% YoY and 19.2% QoQ, driven by strong fee growth in the quarter, including higher insurance collections and higher margins thanks to portfolio growth. 27

Total gross loans of provisions at amortized cost. Total loans at amortized cost increased by 1.2% compared to December 31, 2025, and by 1.3% QoQ, driven by growth in commercial, mortgage, and auto loans. In contrast, credit card and installment purchase loans showed slower growth during the period. Approximately 57% of the loan portfolio is indexed to the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account), given that most mortgage loans and about 35% of commercial loans are denominated in this unit. Additionally, around 21% of commercial loans are denominated in foreign currency, primarily US dollars. Consequently, the performance of these loans has shown some volatility in recent quarters, associated with exchange rate fluctuations. In recent periods, demand for commercial loans remained limited, particularly among large corporates. However, during the quarter, incipient signs of recovery began to emerge, with growth of 1.5% since December 31, 2025, and 1.3% QoQ. This trend was primarily driven by increased demand for financing for foreign trade operations, the effect of which was partially offset by the appreciation of the Chilean peso against the US dollar since December 2025. Secondly, a slight improvement in the growth of non-foreign trade loans was also observed. Mortgage originations increased by 1.4% since December 31, 2025, and by 2.0% QoQ, largely due to a better sales dynamic and higher inflation in the quarter. In recent periods, new loan origination has slowed, reflecting still-weak demand, impacted by rising house prices, as well as the level of inflation and interest rates observed in previous years. However, with an improved economic environment and new measures to encourage home 28

buying, such as those included in the Reconstruction Reform, we expect a gradual recovery in mortgage demand in the coming periods. Consumer loans increased slightly by 0.1% as of December 31, 2025, and decreased by 0.6% QoQ. Within consumer loans is the auto finance business, Santander Consumer, which has shown positive trends with an increase of 4.1% as of December 31, 2025, and a QoQ increase of 1.0% thanks to more commercial agreements with car dealerships. Credit card debt decreased by 1.5% YTD and 2.0% QoQ, while consumer installment loans also declined slightly. This is explained by our customers' improved liquidity position during the quarter, where their funds increased by 4.0% QoQ.

Calculated in accordance with Chilean regulations. The Bank's total deposits increased by 6.0% since December 31, 2025, driven by an 11.8% growth in time deposits, primarily due to increased inflows in the CIB segment. This was partially offset by a slight contraction in demand deposits, associated with normal seasonality compared to year-end. We also saw increased demand for mutual funds, which grew by 9.5% over the same period. Overall, client funds grew by 7.1% since December 31, 2025. In the second quarter (2Q26), total deposits increased by 4.5%. Time deposits grew by 7.0%, while demand deposits increased by 1.4% QoQ. Mutual funds, meanwhile, increased by 3.1% QoQ. Overall, customer funds grew by 4.0% QoQ. Bonds declined 7.6% YoY and 3.5% QoQ, in line with increased liquidity among our clients and slower demand in the long-term loan portfolio. Through June 2026, the Bank issued bonds totaling UF 6,562,000, Ch$ 248,500,000,000, and USD 530,000,000, taking advantage of favorable conditions in both local and international fixed-income markets. Of particular note was the issuance of a USD 500 million 144A bond in January 2026, maturing in November 2030 with a 4.55% interest rate. In terms of liquidity, the Bank's Liquidity Coverage Ratio (LCR), which measures the percentage of liquid assets relative to net cash outflows, stood at 177.1% as of June 30, 2026, well above the regulatory minimum. At the same date, the Bank's Net Stable Funding Ratio (NSFR), which measures the percentage of illiquid assets financed through stable funding sources, was 118.2%, also significantly above the required minimum. 30

This growth is primarily due to reserves resulting from higher profits in fiscal year 2025. Compared to the previous quarter, equity increased 5.0% QoQ due to higher profits and a lower loss recorded in valuation accounts associated with cash flow hedges. The Bank uses these hedges to mitigate the inflation risk of its assets. In the current context of inflation expectations, this has generated an unrealized gain during the quarter. As of June 2026, the Bank maintains a dividend provision of 60% of 2026 profits. At the Annual Shareholders' Meeting held on April 28, 2026, the distribution of a dividend of 60% of the 2025 profits, equivalent to Ch$ 631,925 million, and a dividend per share of Ch$ 3.35 with a yield of 4.5%, was approved. The Bank had already fully provisioned for this dividend. 31

Leverage: Core capital / Total regulatory assets, as calculated by the CMF. Risk-weighted assets (RWAs) increased 5.0% as of December 31, 2025, primarily driven by market RWAs, in a context influenced by global market volatility. During the quarter, our RWAs remained stable at 0.1% QoQ, with a decrease in market RWAs during the quarter, offset by growth in loan RWAs, in line with the growth of the loan portfolio. Regulatory capital has strengthened thanks to higher profit generation, allowing the CET1 ratio to increase organically by 20 basis points as of December 2025, reaching a ratio of 11.1% at the end of 2Q26, above the minimum requirement of 9.08%. Meanwhile, the total BIS ratio reached 16.6% at the close of June 2026. Finally, the ROAE for the last 6 months (6M26) reached 27.2% and 31.5% in the quarter, with the second quarter positively impacted by higher inflation during the period. 32

Net interest and readjustment income accumulated to June 30, 2026 increased by 7.4% compared to the same period in 2025. This growth was driven by a 17.7% increase in readjustment income, favored by a UF variation of 2.7% in 6M26 compared to 2.2% in the same period in 2025. In a context of lower inflation during the first quarter, average exposure to the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account) decreased on average during 2026 compared to 2025. However, given the inflationary rebound recorded during the second quarter, the Bank increased this exposure to capture the higher inflation observed in recent months. Meanwhile, interest income increased by 5.4%, driven primarily by the 3.5% growth in average interest-earning assets and, to a lesser extent, by a slight improvement in funding costs, in line with the decrease in the average Monetary Policy Rate (MPR) from 5.0% to 4.5%. The Bank maintains a shorter duration for its interest-bearing liabilities compared to its assets, allowing liabilities to adjust more quickly to changes in interest rates. As of June 2026, time deposits represented 35.9% of total funding and, given that they typically have a duration of 30 to 60 days, they rapidly capture changes in interest rates. In 2Q26, total net interest and readjustment income increased by 26.9% compared to 1Q26, primarily due to strong growth in readjustment income of 441.2% in 2Q26, where the UF variation increased from 0.3% in 1Q26 to 2.5% in 2Q26. Given the change in the inflation environment, we increased the gap in inflation-linked instruments in the quarter. This was offset by a slight decrease of 2.1% in interest income for the quarter, explained by a higher cost of funds. Compared to 2Q25, total net interest and readjustment income increased by 19.4% in 2Q26, primarily due to the impact of higher inflation, which rose from 1.0% in 2Q25 to 2.5% in 2Q26, leading to a strong increase in readjustment income of 104.8%. Furthermore, interest income grew by 2.8% in 2Q26 compared to 2Q25, driven by a 3.9% increase in interest-earning assets during the period. As a result of these inflationary dynamics, the net interest margin (NIM) increased from 4.1% in 2Q25 and 3.8% in 1Q26 to 4.7% in 2Q26, and from 4.1% in 6M25 to 4.3% in 6M26. 34

Annualized credit loss expense divided by average loans. 2. Balance sheet provisions including additional provisions divided by non-performing loans. The Bank's asset quality continued to reflect the economic environment facing both corporate and retail banking clients. The slower economic activity and weakening labor market observed in recent years resulted in higher levels of non-performing loans and impaired portfolios, requiring a greater level of loan loss provisions. In this context, during 2025 the Bank implemented several initiatives aimed at strengthening portfolio quality, particularly in the commercial segment. During the first quarter of 2026, asset quality indicators remained relatively stable, although one isolated case was recorded in the large corporate segment. This effect was partially reversed during the second quarter, contributing to a decrease in net loan loss expenses. Net credit loss expense totaled Ch$285,583 million in 6M26 and Ch$126,806 million in 2Q26, representing a decrease of 0.4% compared to the same period in 2025, 20.1% compared to 1Q26, and 13.9% compared to 35

2Q25. As a result, the cost of risk increased from 1.43% in 2Q25 to 1.55% in 1Q26 and improved to 1.22% in 2Q26, reaching 1.38% in 6M26. The impaired loan ratio increased from 6.8% in 2Q25 to 7.5% in 2Q26, reflecting loan restructuring. Consequently, the non-performing loan (NPL) ratio increased from 3.0% in 2Q25 to 3.4% in 2Q26, although the pace of deterioration appears to be moderating. It is important to note that asset quality indicators are being impacted by low portfolio growth. Finally, the expected loss ratio (provisions for credit risk divided by total loans) has increased from 3.2% in 2Q25 to 3.3% in 2Q26 as a result of higher provisions established in recent periods, and the non-performing loan coverage ratio (which includes voluntary provisions set out by the Board of Directors in recent years) is at 107.6% in 2Q26.

During the quarter, there were greater recoveries of non-performing consumer loans, and as a result, the non-performing loan ratio for the consumer portfolio improved from 2.2% in 2Q25 and 1Q26 to 2.1% in 2Q26. Meanwhile, the non-performing loan ratio for the consumer portfolio increased from 5.1% in 2Q25 to 5.2% in 1Q26 and 2Q26, indicating greater restructuring of customers during 2026. Consumer loan coverage reached 387% at the end of June 2026. Provisions for commercial loans decreased by 33.2% in 6M26 compared to 6M25, primarily due to lower provisions for the commercial loan portfolio assessed as on a group basis. As mentioned previously, in the first quarter of 2026, a specific company in the mining sector experienced difficulties, leading to an increased provision and the use of additional provisions to cover the client's exposure. Compared to 1Q26, provisions for commercial loans decreased by 72.1% in 2Q26 and by 78.8% compared to 2Q25 due to the release of provisions related to the aforementioned client. The non-performing loan ratio for the commercial loan portfolio increased from 3.6% in June 2025 to 3.7% in March 2026 and 3.9% in June 2026. The impaired loan ratio for commercial loans stood at 8.3% in 2Q25, 9.0% in 1Q26, and 9.1% in 2Q26, taking into account more loans restructured during 2025. On the other hand, the non-performing loan coverage ratio for this portfolio remained high at 119.3% as of June 2026. Provisions for mortgage loans decreased by 55.7% in the first six months of 2026 compared to the same period in 2025 due to lower provisions for non-performing loans and higher recoveries of previously written-off loans. 36

Compared to the previous quarter, they increased by 112.0% QoQ and by 758.2% compared to the second quarter of 2025 due to higher provisions for non-performing loans. The mortgage non-performing loan ratio stood at 3.4% for the quarter, with an impairment ratio of 6.6%. As a result, the non-performing loan coverage ratio for the mortgage portfolio remained at 34.2% in June 2026. For more information on credit risk and asset quality, see Section 8: Risk. Good performance in fees from brokerage of mutual funds and other major products. Net fees remained stable in the six months ended June 30, 2026 compared to the same period in 2025 mainly due to higher fees on our main products such as mutual fund brokerage and current accounts and offset by lower performance in transactional products and other fees. With this, the recurrence ratio (total net commissions divided by structural support expenses) increased from 61.9% YTD to June 2025 to 64.1% YTD to June 2026, demonstrating that almost two-thirds of the Bank's expenses are financed by the commissions generated by our customers. Commissions per product: Financial accounting information The evolution of commissions per product was as follows: YTD % change Quarterly % change Ch$ million Jun-26 Jun-25 Jun-26/ Jun-25 2Q26 1Q26 2Q25 2Q26/ 2Q25 2Q26/ 1Q26 Card fees 73,945 75,134 (1.6%) 35,560 38,385 37,539 (5.3%) (7.4%) Payments 42,704 50,271 (15.1%) 18,686 24,018 25,920 (27.9%) (22.2%) Asset mgt & Insurance 80,561 69,418 16.1% 40,573 39,988 35,561 14.1% 1.5% Accounts and collections 71,405 72,342 (1.3%) 35,779 35,626 36,355 (1.6%) 0.4% Others 27,707 29,529 (6.2%) 10,792 16,915 13,068 (17.4%) (36.2%) Total commissions 296,322 296,694 (0.1%) 141,390 154,932 148,443 (4.8%) (8.7%) Credit and debit card fees decreased by 1.6% in 6M26 compared to the same period in 2025, by 7.4% QoQ, and by 5.3% compared to 2Q25, driven by lower transactionality related to consumer spending and, to a lesser extent, higher expense related to loyalty program campaigns during the quarter. Payment fees are primarily generated by Getnet, the bank's acquiring business. The fees from Getnet experienced a contraction in the quarter and in the first six months of 2026 due to a more competitive environment following a period of strong growth. It currently has approximately 287,000 POS terminals in operation, consolidating its presence in the payments ecosystem. 37

Brokerage fees for asset management and insurance increased 16.1% in 6M26 compared to the same period in 2025 and 14.1% compared to 2Q25, reflecting higher demand, as a result of the expanding customer base, for investment products in a context of lower interest rates and insurance products associated with consumer loans, as well as non-loan-related insurance such as life and auto insurance. Brokerage fees increased 1.5% QoQ also driven by insurance associated with mortgage and consumer loans. Current account and collection fees decreased 1.3% in 6M26 compared to the same period in 2025 and 1.6% compared to 2Q25, mainly due to lower income associated with loan collections and insurance premiums. In the quarter, current account and collection fees increased 0.4% QoQ due to higher fees from current account. Account openings continued to grow during the quarter, reaching a market share of 20.8% as of May 2026. Strong growth in dollar current accounts was also noteworthy, with digital account opening facilitating their adoption. As of May 2026, 507,584 accounts were registered, representing a market share of 36.4%. Other fees decreased by 6.2% in 6M26 compared to the same period in 2025, by 17.4% in 2Q26 compared to 2Q25, and by 36.2% QoQ. Fees for loan prepayments performed well, primarily due to higher prepayments on commercial loans during the quarter. Furthermore, fees from guarantees also showed increased activity in standby letters of credit and cash guarantees during the quarter, although less than in 6M25, when demand from corporate clients and large companies was particularly high. Also noteworthy during the quarter were higher commissions generated by financial advisory services related to client debt restructurings. However, the quarter also saw increased fee expense on guarantee services provided by multilateral development organizations seeking to promote the growth of certain portfolios. Net financial results income increased by 16.0% in 6M26.

This performance is mainly explained by higher gains in the valuation of derivative contracts and by the sale of commercial portfolio and available-for-sale portfolio, partially offset by lower results associated with the foreign currency position. 38

Net financial results increased by 11.8% compared to 2Q25, due to a better result from the valuation of derivative contracts, while this line decreased by 17.4% in 2Q26 compared to 1Q26 with a lower gain from the valuation of derivative contracts in the quarter offset by better results associated with the foreign currency position. 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 % Change Quarterly % Change Ch$ million Jun-26 Jun-25 Jun-26/ Jun-25 2Q26 1Q26 2Q25 2Q26/ 2Q25 2Q26/ 1Q26 Client 133,340 129,346 3.1% 62,626 70,714 59,244 5.7% (11.4%) Non-Client (1) 22,324 4,820 –% 7,780 14,544 3,706 109.9% (46.5%) Total net financial transactions 155,664 134,166 16.0% 70,406 85,258 62,950 11.8% (17.4%) 1. Non-client income. 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 Ch$133,340 million in 6M26, a 3.1% YoY increase and a 5.7% increase compared to 2Q25. This growth was driven by higher demand for fixed-income market making due to increased market volatility. However, revenue from client treasury services decreased by 11.4% QoQ, following a strong first quarter. Non-client treasury income totaled a gain of Ch$22,324 million, mainly explained by the sale of commercial portfolio and ALCO and better hedging results. Efficiency of 31.6% in 6M26 with operating expenses contracting YoY. The Bank's efficiency index reached 31.6% as of June 30, 2026, an improvement over the 35.3% recorded in the same period of the previous year. The efficiency ratio stood at 30.8% in 2Q26, compared to 32.5% in 1Q26 and 35.6% in 2Q25. In line with this, the cost-to-asset ratio decreased to 1.4% in the first six months of 2026. Operating expenses (which include other expenses) decreased by 4.3% compared to 6M25, primarily due to lower administrative costs. It's worth noting that during the first quarter of 2025, the Bank completed a major milestone with Project Gravity, which involved migrating from the mainframe to the cloud. During that period, both systems operated in parallel, resulting in higher costs. Furthermore, the transition to the new cloud infrastructure generated higher amortization and depreciation expenses associated with legacy systems. Compared to 1Q26, operating expenses increased by 7.8%, driven by higher personnel expenses. Personnel expenses in the first quarter of the year show seasonality due to the holiday season in Chile. Operating expenses decreased by 2.0% compared to 2Q25 due to lower personnel and other expenses. 39

Personnel expenses increased by 1.7% in 6M26 compared to 6M25, primarily due to salary readjustments in line with inflation and higher severance payments, in the context of a 4.0% reduction in staff and a 3.0% decrease in the number of branches. This was offset by lower short-term incentives. Compared to 1Q26, personnel expenses increased by 11.7%, mainly due to higher salaries, where, for accounting purposes, the holiday season causes seasonality in this account. This was partially offset by lower severance payments. Compared to 2Q25, personnel expenses decreased by 1.2%, explained by lower severance payments for years of service offset by higher spending on training and salaries in line with inflation. Administrative expenses decreased by 9.3% in 6M26 compared to the same period in 2025 due to lower technology and data processing expenses, largely related to the aforementioned Gravity project. Compared to 40

1Q26, administrative expenses increased by 3.4% due to higher IT and communications spending. Compared to 2Q25, administrative expenses remained stable. Depreciation expenses decreased 2.0% in 6M26 compared to the same period in 2025 and 2.2% in 2Q26 compared to 2Q25, primarily due to lower depreciation of internally developed software. Compared to 1Q26, depreciation expenses decreased 6.9% QoQ due to the aforementioned factors, in addition to higher equipment depreciation during the quarter. Other operating expenses decreased 11.6% in 6M26 compared to the same period in 2025, mainly due to the release of provisions associated with other contingencies in 1Q26. Compared to 1Q26, other operating expenses increased 49.7% QoQ due to the aforementioned release of provisions, which was not repeated in 2Q26. Compared to 2Q25, other operating expenses decreased 10.5% due to lower financial leasing credit operating expenses.

For tax purposes, capital must be adjusted for inflation; therefore, when inflation is high, the effective tax rate tends to be lower. As of June 2026, the effective tax rate was 14.6%. 41

Section 7: Management Perspectives The Bank's Management continuously evaluates the evolution of the economic, regulatory, and competitive environment, as well as trends that could influence the institution's future performance. In this context, the perspectives presented in this section reflect Management's current view of the main challenges, opportunities, and factors that could impact the Bank's ability to generate sustainable value and maintain a solid financial position in the short, medium, and long term. These perspectives consider the Bank's defined strategy, its risk profile, the expected evolution of the markets in which it operates, and the capabilities developed to respond to a constantly changing environment. Furthermore, Management continuously monitors financial, commercial, operational, and sustainability indicators to support timely decision-making and strengthen value creation for clients, employees, shareholders, and other stakeholders. With all of the above in mind, the Bank's expectations for growth in volumes, capital and results for the year 2026 are as follows: Indicator Initial expectation Updated outlook 2Q26 Key factor Loan growth Mid single digits Mid single digits Demand reactivation driven by macro environment. NIM C. 4.0% C. 4.1% Baseline macroeconomic environment for interest rates and inflation and the asset and liability mix. Non NII growth Mid to High Single Digits Mid-Single Digits Customer growth and product usage. Does not include potential regulatory changes related to interchange fees. Efficiency Mid 30s% Low 30s% Inflation, total employees, exchange rate, productivity, and investment plans. Cost of credit c. 1.3% c. 1.35% Subject to the evolution of the cycle. ROAE 22-24% +24% Based on our estimates of key components including inflation, rates, and business growth. Regarding capital management, on July 3, the CMF (Financial Market Commission) held a second public consultation on the regulation updating the calculation of market risk weighted assets (MRWA), which had a two-week deadline. The CMF estimates that this will help reduce the system's MRWA by approximately 36%. The Bank is awaiting the final regulation to calculate an estimate of the impact on capital ratios, which should be positive. The Bank's Research team projects stronger economic growth in 2027, coupled with inflation converging to the Central Bank's target range of 3% and a potential reduction in the monetary policy rate. This scenario should boost customer demand for loans in the coming year. In the long term, ROAE is estimated to be above 20%, subject to macroeconomic projections and other external factors. 42

Section 8: Risks Risk management in 2Q26 has focused on strengthening our risk structure in the face of weak economic activity and the labor market as described in Section 3 of this document. Credit risk Estimated expected loss: The provision estimate is based on expected loss models, in accordance with Chapter B1 of the CMF's Compendium of Accounting Standards. The loan portfolio is divided into 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: Further information on the loan models can be found in note 2 of the Bank's financial statements. Below you can see more details of the loan portfolio. 43

During 2025, the Bank implemented several initiatives to strengthen portfolio quality, including write-offs. However, in the first quarter of 2026, a one-off deterioration was observed for a commercial client assessed on an individual basis. This led to an increase in the loan loss provision coverage for this exposure, which was reversed during the second quarter. As a result, the commercial non-performing loan ratio reached 3.9% in June 2026, while the impaired loan ratio increased from 8.6% in December 2025 to 9.1% at the end of June 2026. In the mortgage portfolio, a deterioration was observed during 2024, associated with lower household liquidity and an increase in the total installment in the recent years due to high inflation. During 2025, clients began renegotiating their loans, and NPLs showed signs of stabilization, reaching 3.1% in December 2025 and 3.4% in June 2026. Meanwhile, the impaired loan ratio reached 6.3% and 6.6%, respectively. It is worth noting that these loans are secured by real estate, maintaining a loan-to-value (LTV) ratio of around 60% of the outstanding loan portfolio. The consumer portfolio continues to show good performance with a stable impairment ratio of 5.2% and an improvement in the NPL ratio from 2.5% in December 2025 to 2.1% in June 2026. Total loan provisions decreased 0.4% YoY and 20.1% QoQ, explained by the specific case of the commercial portfolio, which was reversed in 2Q26. With that, the non-performing loan coverage ratio, including additional provisions, reached 107.6% in June 2026, and the expected loss ratio (loan loss provisions divided by total loans) increased to 3.3%. Significant rainfall has been recorded in various parts of the country during July, particularly in the Atacama and Coquimbo regions, where unusually high levels for this time of year have been observed. Management is continuously monitoring the evolution of these events and their potential effects on client activity and the various 45

business segments. In this regard, no material impacts on the loan portfolio or significant changes in the Bank's main risk and asset quality indicators are anticipated. Furthermore, this rainfall has contributed to the recovery of reservoirs and water reserves in several regions of the country, especially in the north, strengthening the future availability of water resources for economic activities dependent on this resource. The Bank will continue to assess the evolving situation and its potential impact on economic activity and specific productive sectors, maintaining prudent and timely management of associated risks.

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 team, which is part of the Risk Division. Limits are approved by the various committees in charge, primarily the Market Committee and the Assets and Liabilities Committee (ALCO). The main market risks are also reviewed by the Integrated 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 the Risk Management: • Optimizing the cost of liabilities by seeking the most efficient financing strategies, including the issuance of bonds and bank lines of credit. • 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 using a portfolio of liquid assets to ensure the Bank always maintains sufficient liquidity to cover short-term fluctuations and long-term financing, in compliance with internal regulatory liquidity requirements. The Financial Management Department receives information from all business units regarding the liquidity profile of their financial assets and liabilities, as well as a breakdown of other projected cash flows from future business activities. Based on this information, the area maintains a portfolio of short-term liquid assets, primarily consisting of liquid investments, loans, and advances to other banks, to ensure the Bank has sufficient liquidity. The liquidity needs of the business units are met through short-term transfers from Financial Management to cover short-term fluctuations and long-term financing to address all structural liquidity requirements. The Bank monitors its liquidity position daily, determining future cash inflows and outflows. Additionally, stress tests are conducted at the end of each month, using a variety of scenarios that encompass both normal market conditions and market fluctuations. Liquidity policies and procedures are subject to review and approval by the Bank's Board of Directors. Periodic reports are generated by the Market Risk Department, detailing the liquidity position of the Bank and its subsidiaries, including exceptions and corrective measures taken. These reports are submitted periodically to the ALCO for review. The Bank obtains demand and time deposits from its customer base, while 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, with a large proportion 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 through continuous monitoring of market trends and pricing management. 47

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. According to Basel III standards, these assets are divided into three tiers, with Tier 1 assets being the most liquid and Tier 3 assets the least liquid. As of June 30, 2026, the Bank's HQLA amounted to $8,446,542 million and corresponded mainly to Level 1 liquid assets, composed mainly of bonds of the Republic of Chile, Central Bank of Chile and United States Treasury. Liquid Assets (Consolidated Ch$ million) Tier 1: Available, 1,697,584 Tier 1: Fixed Income, 6,746,426 Tier 2: Fixed Income, 2,532 Regarding 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 relative to net cash outflows. This indicator is required by Basel III standards and provides a sustainable maturity structure for assets and liabilities, enabling banks to maintain a stable funding profile relative to their operations. As of June 30, 2026, this indicator for Banco Santander Chile stood at 177.1% above the minimum (100%). This reflects the conservative liquidity requirements established by the board of directors through the ALCO committee. 48

As of June 30, 2026, the NSFR stood at 118.2%.

To manage this risk, Banco Santander Chile conducts a sensitivity analysis regarding both local and foreign currencies. Through simulations, limits are set on the maximum potential loss that interest rate movements could have on capital and net financial income budgeted for the year. 49

Due to the rules established by the Assets and Liabilities Committee (ALCO), the Bank should not have significant exposure to foreign currencies; therefore, all exchange rate 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 for the trading portfolio, which includes foreign exchange risk and interest rate risk.

Risk of inflation The Bank holds assets and liabilities that are adjusted according to the variation of the Unidad de Fomento (UF). Generally, the Bank has more assets than liabilities denominated in UF, and therefore, moderate increases in inflation have a positive effect on adjustment income, 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-bearing assets. Operational risk As of June 30, 2026, the operating profit from operational risk totaled Ch$20,193 million, mainly related to higher expenses for external fraud compared to the same period in 2025. 51
