Section 1: Highlights Solid financial performance with a ROAE1 of 24.5% in 9M262 and profit growth of 11.9% YoY3. As of September 30, 2026, net income attributable to the Bank's owners totaled $893 billion (US$4.74 per share and US$1.94 per ADR). Compared to the same period of the previous year, net income increased by 11.9%, reaching a ROAE of 24.5% in 9M26 versus 24.0% in 9M254. This is mainly due to higher net interest income resulting from higher inflation in the readjustment income line, as the UF variation was 3.3% in 9M26 compared to 2.8% in 9M25. 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 dividends of 60% of the profits from the 2025 fiscal year. This is a dividend of $3.35 per share and a yield of 4.5%. In the third quarter of 2026, net income attributable to the Bank's owners totaled $237 billion ($1.30 per share and US$0.50 per ADR). Compared to the previous quarter (2Q26), it decreased 38.0% QoQ5 and 4.2% compared to 3Q256, primarily due to lower net income from readjustments in a quarter with lower inflation (0.6% in 3Q26 vs. 2.5% in 2Q26 and 0.6% in 3Q25), as well as lower fee income and higher provisions during the quarter. Despite these factors, ROAE reached 19.1% in 3Q26. Total equity increased 5.7% during the year, including a dividend distribution provision of 70%. Total equity reached $5,114,925 million as of September 30, 2026, a 5.7% increase compared to December 31, 2025. This growth is primarily due to reserves resulting from higher profits in fiscal year 2025. Additionally, as of September 2026, the Bank increased its dividend provision from 60% to 70% of 2026 profits. The Bank maintains a stable CET17 ratio of 10.9% with a capital adequacy ratio8 of 16.3% as of September 2026. Customer funds grow 3.7% in the quarter. The Bank's total deposits increased by 9.0% as of December 31, 2025, driven by an 18.1% growth in time deposits. This was partially offset by a slight contraction in demand deposits, associated with the usual seasonality compared to the previous year-end; however, demand deposits have increased by 5.5% compared to September 2025. We have also seen increased demand for mutual funds, which grew by 15.5% YTD9. Overall, client funds have grown by 11.1% as of December 31, 2025. 4 1Net profit attributable to owners of the Bank annualized divided by the average equity attributable to equity holders. 2The nine months ending September 30, 2026. 3Year on year. 4The nine months ending on September 30, 2025. 5Quarter versus quarter. 6Third quarter of 2025. 7Common Equity Tier 1 divided by risk-weighted assets, under Chilean regulation. 8Tier 1 + Tier 2 capital divided by risk-weighted assets, under Chilean regulation. 9 Year-to-date


 
In the third quarter (3Q26), total deposits increased by 2.8% QoQ. With lower expectations of cuts to the Monetary Policy Rate, time deposits grew by 5.6%, while demand deposits decreased slightly by 0.8% QoQ. Meanwhile, mutual funds increased by 5.5% QoQ. Overall, customer funds grew by 3.7% QoQ. Total loans grew 1.8% QoQ, driven by higher demand for loans from large companies Total loans at amortized cost increased by 3.0% compared to December 31, 2025 and by 1.8% QoQ, driven by growth in commercial, mortgage, and auto loans. During the second and third quarters, incipient signs of recovery in commercial loans began to appear, with growth of 5.5% since December 31, 2025, and 4.0% QoQ. This trend was primarily driven by increased demand for financing for foreign trade loans and the depreciation of the Chilean peso against the US dollar since December 2025. Secondly, it was also influenced by improved growth in non-trade-export commercial loans to large companies. Within consumer loans is the auto financing business, Santander Consumer, which has maintained positive trends with an increase of 6.3% since December 31, 2025 and an increase of 2.1% QoQ thanks to greater commercial agreements with car dealerships. Best-in-Class in the industry, with an efficiency10 of 33.0% in 9M26 with operating expenses contracting YoY. The Bank's efficiency ratio reached 33.0% as of September 30, 2026, an improvement over the 35.9% recorded in the same period of the previous year, and the efficiency ratio stood at 36.1% in 3Q26. In line with this, the cost- to-asset ratio decreased to 1.4% in the first nine months of 2026. Operating expenses (which include other expenses) decreased by 4.2% compared to 9M25, primarily due to lower administrative costs. It's worth noting that during the first quarter of 2025, the Bank completed a significant 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. During 3Q26, operating expenses decreased by 1.4% compared to 2Q26 and by 4.0% compared to 3Q25, explained by lower other operating expenses in the quarter. 5 10Operating expenses including impairment and other operating expenses/ margin+commissions+ financial transactions and other net operating income.


 
Net interest income and readjustments increased 7.0% YoY with a NIM11 of 4.1% in 9M26. Net interest and readjustment income accumulated to September 30, 2026 increased by 7.0% compared to the same period in 2025. This growth was driven by a 21.8% increase in readjustment income, favored by a UF variation of 3.3% in 9M26 compared to 2.8% in the same period in 2025. In 3Q26, total net interest and readjustment income decreased by 18.1% compared to 2Q26, mainly due to a sharp contraction in readjustment income of 64.6% in 3Q26, where the variation of the UF decreased from 2.5% in 2Q26 to 0.6% in 3Q26. Meanwhile, interest income in the quarter remained stable compared to the previous quarter. As a result of these inflationary dynamics, the net interest margin (NIM) reached 3.8% in 3Q25, 4.7% in 2Q26 and 3.8% in 3Q26. In cumulative terms, the NIM increased from 4.0% in 9M25 to 4.1% in 9M26. Customer base expansion continues, with total customers increasing by 7.5% YoY. The strategy of strengthening digital products has led to continued growth in our customer base, reaching over 4.9 million customers, of which 2.7 million are active. The Bank's market share in current accounts remained strong, reaching 20.4% as of July 2026. Likewise, the increased use of digital platforms continued to drive fee income, with YoY growth of 13% in mutual fund brokerage and insurance. As a result, the recurrence ratio (total net fees divided by structural support expenses) reached 60.8% YTD as of September 2026, demonstrating that almost two-thirds of the Bank's expenses are financed by fees generated by customers. 6 11NIM: Net interest margin.

Macroeconomic Environment During the third quarter of 2026, the Chilean economy operated in a challenging external environment. The conflict in the Middle East kept fuel prices high, especially for refined products, while higher food and freight costs put pressure on the prices of imported goods. Major central banks reinforced their restrictive stance in the face of resilient global activity and the risk of the energy shock being passed on to underlying inflation. In this context, local long-term interest rates rose in line with those in the United States. Even so, the sovereign spread remained narrow, and copper continued to be a significant support for the external accounts. Domestically, activity remained weak. The Imacec (Monthly Index of Economic Activity) fell 1.0% YoY and 0.7% month-on-month in August, seasonally adjusted, mainly due to a 17.4% YoY contraction in mining, which reached its lowest level since 1996. The non-mining component rebounded 0.7% month-on-month, but only reversed the decline of July and remained practically stagnant compared to the end of 2015. In this context, we project zero growth for 2026, with risks still skewed to the downside by potential climate disruptions and transitory shocks that continue to affect mining production. For 2027, we anticipate an expansion of 3.5%, supported by the normalization of the mining sector, a low base of comparison, and greater implementation of large investment projects, mainly in mining and energy. This is further bolstered by the effect that the Reconstruction Law is expected to begin to take hold. Currently, some leading indicators, such as non- energy imports and perceived demand for credit, are beginning to show early signs of increased dynamism, although still insufficient to confirm a widespread recovery in domestic demand. The labor market showed a deterioration during 2026, in line with the weakness in economic activity. Slower formal job creation and low wage growth limited household spending. We expect the job recovery to be gradual and to lag behind the increased dynamism of economic activity, supported by project implementation. In terms of prices, the CPI rose 0.4% month-on-month in September, one-tenth of a percentage point below expectations, and annual inflation remained at 4.1%. Pressures continued to be concentrated in volatile components, especially energy and food, while the CPI excluding volatile items fell to 3.2% annually, consistent with weak domestic demand. Nevertheless, high international fuel prices and the depreciation of the peso are expected to push inflation up to 5.5% by the end of 2026, before converging back toward the target during the following year. The divergence between higher headline inflation and contained core inflation reduces the need to respond to the shock with an immediate rate hike. We therefore maintain our policy rate projection at 4.5% through 2027. The balance of risks, however, is tilted toward a more restrictive path if the energy shock is prolonged, if the exchange rate remains depreciated, or if two-year inflation expectations begin to deviate from 3%. 11

Advances in Risk-Weighted Asset (RWA) models The implementation of Basel III in Chile continues to progress through adjustments to Risk-Weighted Asset (RWA) models, focusing on market risk and credit risk. These changes aim to ensure that capital requirements more accurately reflect the risks assumed by banks, bringing local regulations closer to international standards and improving comparability with other jurisdictions. Regarding market risk, on September 11, 2026, the CMF published the final regulation incorporating the duration method as an alternative for measuring overall interest rate risk in determining Market Risk-Weighted Assets (MRWA). This approach allows for a more accurate capture of the sensitivity of positions to interest rate movements. Its adoption is voluntary and requires CMF approval, for which entities must demonstrate proper implementation through methodological, control, and internal validation documentation. According to previous CMF estimates, this modification would reduce the system's MRWA by approximately 36%. Additionally, the regulation continues to advance in defining criteria for the exclusion and offsetting of derivatives positions, with the aim of better reflecting the effects of hedging in the calculation of MRWA. Regarding credit risk, in August the CMF launched a public consultation on a new regulatory framework that consolidates and refines the requirements for adopting internal models for calculating provisions and risk- weighted assets. The proposal includes foundational and advanced methodologies. It also requires that the initial application cover at least 20% of modelable exposures and establishes a five-year timeframe for achieving full coverage, meaning its implementation would be phased in. Law of National Reconstruction and Economic and Social Development On October 17, 2026, Law No. 21,850 on National Reconstruction and Economic and Social Development was published, with measures to be implemented gradually between November 2026 and 2029. Among its main components is a tax agenda aimed at strengthening investment, improving competitiveness, and supporting economic recovery. The law includes a gradual reduction of the First Category Tax rate from 27% to 25.5% in 2027, 24% in 2028, and 23% from 2029 onward. Furthermore, starting in 2027, the tax system will be fully restructured, simplifying the tax structure, reducing the cost of capital, and increasing incentives for private investment. Furthermore, starting December 1, 2026, and for a period of twelve months, the first sale of new homes with final municipal approval will be exempt from VAT. This measure aims to accelerate the absorption of available housing stock, stimulate the real estate and construction sectors, and facilitate access to housing. Additionally, the law 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. Mortgage Subsidy Law On May 20, 2025, Congress approved the Mortgage 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. 13


 
The project aimed to provide 50,000 subsidies, 10% of which were 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. In 2026, the program was expanded, increasing the number of available subsidies from 50,000 to 80,000 and raising the maximum value of eligible homes from 4,000 UF to 6,000 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 September 25, 2026, 113,781 eligible applications had been received and commercially approved, and more than 33,033 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 began in August, while in September the Guaranteed Universal Pension (PGU) for individuals aged 75 and over increased. Several operational measures have already been implemented. Among these, mandates have already been awarded for the administration of the autonomous pension protection funds (FAPP), and the publication of the Investment Regime for Generational Funds defines the investment structure, risk limits, and benchmark portfolios of the funds that will replace the multi-funds starting in April 2027. 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, even though the final impact will depend on the implementation of the new investment rules of the new system. 14


 
Interchange fees In February 2023, the Interchange Rate 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 fee Proposed second 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. To date, the future trajectory of interchange fees remains uncertain. The second cut remains suspended, and at the committee meeting on September 24, it was recorded in the minutes that the consultant hired to conduct the study presented the preliminary report with the results, which received feedback and is still pending final approval. 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 is public and free of charge, and is 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. 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 Law and Open Finance System The Open Finance System (SFA) originated from the Fintec Law (Law No. 21,521), published in January 2023, which established the legal framework for the secure and consensual exchange of financial information. In July 2024, the CMF issued NCG No. 514, which regulates the SFA, defines the participation obligations of regulated entities and the voluntary registration of new providers, and set its entry into force for July 2026. This timeframe raised concerns about operational feasibility, implementation costs, and the maturity of the technical standards. 15


 
Therefore, between July 2025 and February 2026, the CMF conducted three public consultations to adjust the schedule and detail the system's technological standards, including payment initiation. 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. Currently, the law is still scheduled to come into effect on December 1, 2026. However, in September 2026, the Government submitted a bill proposing to postpone its entry into force to December 1, 2027, and strengthen the structure of the Data Protection Agency. As of October 19, 2026, this amendment is still under legislative review, so the current legal date remains December 2026. 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. 16


 
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. Capital Markets Reform On September 9, 2026, the Executive Branch submitted to Congress the Capital Market Reform and Homeownership Financing Bill, which includes more than 30 measures organized into four pillars: access to housing and promotion of savings; financing for companies of different sizes; modernization of financial market regulations and processes; and strengthening Chile as a regional financial center. Among its main measures are the creation of the National Housing Fund (FONAVI), with government contributions of up to US$2 billion, intended to finance mortgage loans for first-time homebuyers up to 6,000 UF (Unidades de Fomento). The bill also includes Voluntary Housing Savings (AVV), which supplements down payment savings with a government subsidy; the creation of a Junior Segment on the Stock Exchange for emerging and mining exploration companies; and tax adjustments to financial instruments. On October 27, the Chamber of Deputies approved the bill, which now begins its second constitutional review in the Senate. Regulation and supervision In Chile, only banks can maintain checking 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 strategic advances 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 September 2026 Total customers 4,052,314 4,311,488 4,608,182 4,923,793 Active customers 2,398,741 2,556,462 2,693,441 2,728,481 Total customers increased by 7.5% YoY, while active customers grew by 1.8% YoY.

According to the latest publicly available information from the CMF as of July 2026, the Bank holds a 20.4% share of all checking accounts for both individuals and businesses, a figure that does not include demand deposit accounts. Meanwhile, demand for dollar checking accounts continues to show positive growth. As of May 2026, the market share reached 35.9%, 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, its acquiring partner, and by an offering of 100% digital current accounts. These accounts include access to a debit card and Office Banking, the transactional platform for businesses. This comprehensive approach allows 21


 
the company to meet its clients' transactional needs and support them in the development and growth of their businesses.

Likewise, strengthening relationships with this segment and the convenience of digital channels contributed to a 3.6% 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 their position as a leading player in the acquiring market, initially distinguished by rapid growth and currently by a significant market share. As of September 2026, Getnet boasts nearly 297,000 operational POS terminals and over 238,000 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 growth has been reflected in strong financial results compared to its competitors and in sustained expansion of 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 22


 
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. More than 40% of our branches operate without handling cash. As of September 2026, the Bank has a total of 219 branches, 115 of which operate under the traditional format. Since launching the Work/Café model in 2016, 94 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 without handling cash. 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 September 30, 2026.

This trend was partially offset by slower growth in consumer lending, particularly credit cards, due to improved liquidity among our clients. In line with this, deposits in this segment increased by 4.2% YoY and 0.2% QoQ. Net income in this segment increased 5.4% YoY driven by a higher margin, impacted by higher inflation of 3.3% in 9M26. Provision expenses increased 4.3% YoY due to higher provisions in line with the evolution of asset quality, explained in more detail in Section 8: Risks. After very high inflation in the second quarter, the normalization of the UF (Unidad de Fomento) devaluation to 0.6% in 3Q26 resulted in lower margin income. Also in the third quarter, there was a normalization of provisions due to the reversal in 2Q26 of a provision established in 1Q26 for a client in the corporate portfolio. Therefore, net income from this segment decreased by 28.2% QoQ. Wealth Management & Insurance (WM&I) Wealth Management & Insurance's loan portfolio grew 20.5% YoY and 11.2% QoQ, driven by increased commercial general-purpose and mortgage lending. Deposits increased 12.5% YoY and 10.7% QoQ, reflecting our clients' improved liquidity position during the quarter. Net income increased 11.3% YoY, primarily due to higher margins resulting from growth in customer loans and funds. Additionally, compared to 2025, net income in this segment increased due to higher fees generated by mutual funds and travel-related insurance. Net income decreased 8.8% QoQ, mainly due to lower margins resulting from lower UF (Unidad de Fomento) devaluation during the quarter and financial transaction results. Corporate Investment Banking (CIB) CIB's loan portfolio grew by 5.5% YoY and 3.3% QoQ, reflecting improved performance compared to previous periods, particularly in the foreign trade portfolio during the last quarter. Deposits increased by 20.5% YoY and 6.5% QoQ, driven by strong relationships with these clients and an improved liquidity position. 28


 
Net income increased 4.5% YoY, driven by strong margin and fee growth. On a quarterly basis, it decreased 2.1% QoQ, primarily due to the lower impact of the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account) on margin. Payments Payments had a weaker quarter with less transactional activity from customers due to increased market competition and therefore greater price pressure. Digital Consumer Bank The Digital Consumer Bank portfolio grew 6.3% YoY compared to December 31, 2025, and 1.3% QoQ. Net income from this segment increased 17.9% YoY due to stronger portfolio growth and robust fee growth. Net income decreased 21.8% QoQ, impacted by lower UF (Unidad de Fomento) inflation during the quarter and slower fee growth. 29


 
Section 6: Financial Performance Balance sheet Total loans grow 1.8% QoQ, driven by higher demand for loans to large companies Loans by product: Financial accounting information YTD % Change (Ch$ million) Sept-26 Jun-26 Dec-25 Sept-26/ Dec-25 Sept-26/ Jun-26 Consumer loans 6,038,627 6,065,982 6,057,304 (0.3%) (0.5%) Santander Consumer (car loans) 1,148,874 1,125,338 1,080,862 6.3% 2.1% Credit cards 1,960,306 2,030,414 2,061,691 (4.9%) (3.5%) Other consumer loans 2,929,447 2,910,228 2,914,751 0.5% 0.7% Mortgage 17,779,978 17,696,111 17,443,563 1.9% 0.5% Commercial 18,315,178 17,616,970 17,363,835 5.5% 4.0% Interbank 19,729 47,565 68,178 (71.1%) (58.5%) Total(1) 42,153,512 41,426,628 40,932,880 3.0% 1.8% 1. Total loans at amortised cost, gross of provisions. Total loans at amortized cost increased by 3.0% compared to December 31, 2025, and by 1.8% QoQ, driven by growth in commercial, mortgage, and auto loans. In contrast, credit card lending showed less dynamism during the period. Approximately 56% 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 33% of commercial loans are denominated in this unit. Additionally, around 23% 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 companies. However, during the second and third quarters, incipient signs of recovery began to appear, with growth of 5.5% since December 31, 2025, and 4.0% QoQ. This trend was primarily driven by increased demand for financing for foreign trade loans and the depreciation of the Chilean peso against the US dollar since December 2025. Secondly, it was also influenced by improved growth in non-trade credit for large companies. Mortgage originations increased by 1.9% since December 31, 2025, and by 0.5% QoQ, driven by improved sales dynamics and offset by lower 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 inflation and interest rates observed in previous years. However, with an improved economic environment and new measures to encourage home 30


 
purchases, such as those included in the Reconstruction Reform, we expect a gradual recovery in mortgage demand in the coming periods. Consumer loans decreased slightly by 0.3% as of December 31, 2025, and by 0.5% QoQ. Within consumer loans is the auto finance business, Santander Consumer, which has shown positive trends with an increase of 6.3% as of December 31, 2025, and a increase of 2.1% QoQ, thanks to more commercial agreements with car dealerships. Credit card spending decreased by 4.9% since December 31, 2025, and by 3.5% QoQ, while consumer installment loans also increased slightly. The third quarter was affected by lower transaction volume and card usage, reflecting a weaker socio-economic environment and the new minimum payment regulations, which accelerate the amortization of the loan.

This figure is not included in the Bank's consolidated financial statements. 2. It includes regulatory capital financial instruments (AT1 and Tier 2). 3. Calculated in accordance with Chilean regulations. The Bank's total deposits increased by 9.0% since December 31, 2025, driven by an 18.1% growth in time deposits. This was partially offset by a slight contraction in demand deposits, associated with normal seasonality compared to the previous year-end. We also saw increased demand for mutual funds, which grew by 15.5% over the same period. Overall, client funds grew by 11.1% since December 31, 2025. In the third quarter (3Q26), total deposits increased by 2.8% QoQ. With lower expectations of cuts to the Monetary Policy Rate, time deposits grew by 5.6% QoQ, while demand deposits decreased slightly by 0.8% QoQ. Meanwhile, mutual funds increased by 5.5% QoQ. Overall, customer funds grew by 3.7% QoQ. Bond issuance decreased by 6.1% since December 31, 2025, and by 2.2% QoQ , in line with increased liquidity among our clients and slower demand in the long-term loan portfolio. Through September 2026, the Bank issued bonds totaling UF 6,855,000,000, CLP 253,500,000,000, CHF 100,000,000, and USD 555,000,000, taking advantage of favorable conditions in both local and international fixed-income markets. Of particular note is 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 172.3% as of September 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 116.9%, also significantly above the required minimum. 32

This growth is primarily due to reserves resulting from higher profits in fiscal year 2025. Compared to the previous quarter, equity decreased 0.5% QoQ due to a larger loss in valuation accounts, related to the cash flow hedges the Bank uses to mitigate the inflation risk of its assets. Given current inflation expectations, these hedges resulted in an unrealized loss during the quarter. Additionally, as of the end of September 2026, the Bank increased the dividend provision from 60% to 70% of 2026 profits. At the Annual General Meeting of Shareholders 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. 33

Risk-weighted assets (RWAs) increased 7.7% as of December 31, 2025, and 2.6% QoQ, driven primarily by credit RWAs, in a context of emerging signs of increased loan demand. Regulatory capital has strengthened thanks to higher profit generation, and the CET1 ratio reached 10.9% at the end of September 2026, above the minimum requirement of 9.08%. The Bank's core capital includes the negative impact of the increase in the dividend provision from 60% to 70% of profits in September 2026. Meanwhile, the capital adequacy ratio reached 16.3% at the end of September 2026. Finally, the ROAE for the last nine months (9M26) reached 24.5% and 19.1% in the third quarter, with the third quarter impacted by lower inflation during the period. On October 21, 2026, the Bank issued a perpetual bond, qualifying as Additional Tier 1 capital (“AT1”), for a total amount of USD 700 million, with an annual interest rate of 8.0% (a spread of 307bp above the Treasury), which were fully subscribed by a company of the Santander Group. Settlement of this issuance took place on October 26, 2026, and, using the proceeds, the Bank redeemed the AT1 bond issued in October 2021 on the same date. Interest on the new issuance will be paid semi-annually, in April and October of each year. 34

Gross interest and inflation-linked expense divided by the sum of interest-earning liabilities and demand deposits. 4. Net interest and inflation-linked income divided by average earning assets. 5. Inflation measured as the variation of the UF in the period. Net interest and readjustment income accumulated to September 30, 2026 increased by 7.0% compared to the same period in 2025. This growth was driven by a 21.8% increase in readjustment income, favored by a UF variation of 3.3% in 9M26 compared to 2.8% in the same period in 2025. 35


 
Average exposure to the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account) in 2026 was higher than in 2025, given the inflationary rebound in the second quarter when the Bank increased this exposure to capture the higher inflation and then reduced the exposure during the third quarter. Meanwhile, interest income increased by 4.5% YoY, driven primarily by the 4.4% growth in average interest-earning assets and, to a lesser extent, by a slight improvement in the cost of funding, in line with the decrease in the average Monetary Policy Rate (MPR) from 4.9% 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 the end of September 2026, time deposits represented 38.5% of total funding and, given that they typically have a duration of 30 to 60 days, they rapidly capture variations in interest rates. In 3Q26, total net interest and readjustment income decreased by 18.1% compared to 2Q26, mainly due to a sharp contraction in readjustment income of 64.6% in 3Q26, where the variation of the UF decreased from 2.5% in 2Q26 to 0.6% in 3Q26. Meanwhile, interest income in the quarter remained stable compared to the previous quarter. Compared to 3Q25, total net interest and readjustment income increased 6.2% in 3Q26, primarily due to greater exposure to the UF (Unidad de Fomento, a Chilean inflation-indexed unit of account), which increased 19.8% in the quarter compared to 3Q25. This led to strong growth in readjustment income of 38.1% in 3Q26. Furthermore, interest income grew 2.9% in 3Q26 compared to 3Q25 due to growth in interest-earning assets of 6.1% during the period. As a result of these inflationary dynamics, the net interest margin (NIM) reached 3.8% in 3Q25, 4.7% in 2Q26 and 3.8% in 3Q26. YTD the NIM increased from 4.0% in 9M25 to 4.1% in 9M26.

Annualized credit loss expense divided by average loans. 2. Balance sheet provisions including additional provisions divided by non-performing loans. During 2026, risk levels have shown a trend toward normalization, although with some isolated cases in the commercial loan portfolio. Following the increase in non-performing loans and impaired portfolios observed in previous years, in a context of lower economic activity and a weakening labor market, asset quality indicators have begun to stabilize. Net credit loss expense totaled $442,631 million in 9M26 and $157,048 million in 3Q26, representing a 2.8% increase compared to the same period in 2025, a 23.8% increase compared to 2Q26, and a 9.3% increase compared to 3Q25. Therefore, the cost of risk decreased from 1.39% in 3Q25 to 1.22% in 2Q26 and then increased to 1.48% in 3Q26. YTD, it reached 1.42% in 9M26. The impaired loan ratio increased from 6.8% in 3Q25 to 7.4% in 3Q26, reflecting loan restructuring. Consequently, the non-performing loan (NPL) ratio rose from 3.1% in 3Q25 to 3.5% in 3Q26, although the rate of deterioration is moderating. It is important to note that quality indicators are being affected by low portfolio growth. Finally, the expected loss ratio (provisions for credit risk divided by total loans) has increased from 3.2% in 3Q25 to 3.4% in 3Q26 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 105.7% in 3Q26.

Provisions for consumer loans increased by 6.4% in 9M26 compared to 9M25, driven by higher write-offs which were offset in part by higher recoveries of written-off loans during the period. Provisions for consumer loans decreased by 34.3% compared to 2Q26 and by 30.4% compared to 3Q25, driven by lower provisions related to the contraction of the credit card portfolio and, in particular, lower provisions made among our high-income customers. This was partially offset by the regulatory change regarding minimum credit card payments, which increased the minimum payment required by customers, leading to greater payment difficulties and delinquencies. With this, the non-performing loan ratio for the consumer loan portfolio improved from 2.4% in 3Q25 to 2.1% in 2Q26 and 2.3% in 3Q26, while the impaired ratio for the consumer loan portfolio increased from 5.2% in 3Q25 and 2Q26 to 5.5% in 3Q26. Consumer loan portfolio coverage reached 360% at the end of September 2026. Provisions for commercial loans increased by 2.7% in 9M26 compared to 9M25, primarily due to stronger portfolio growth, particularly in the last quarter. Compared to 2Q26, provisions for commercial loans increased by 395.8% in 3Q26 and by 104.3% compared to 3Q25. This increase was due to higher provisions in 1Q26 specifically related to a mining company, whose situation was reversed in 2Q26 with the release of these provisions. Additionally, other specific individual exposures showed weaknesses in 3Q26, leading to higher provisions. With this, the non-performing loan ratio for the commercial loan portfolio increased from 3.4% in September 2025 to 3.9% in June 2026 and 4.0% in September 2026. The impairment ratio for commercial loans stood at 8.2% in 3Q25, 9.1% in 2Q26, and 8.7% in 3Q26. Meanwhile, the non-performing loan coverage ratio for this portfolio remained high at 114.5% as of September 2026. Provisions for mortgage loans decreased by 32.1% in the first nine 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. Compared to the previous quarter, they increased by 43.6% QoQ and by 48.7% compared to the third quarter of 2025 due to higher provisions related to a larger portfolio of non-performing loans. In the quarter, the mortgage NPL ratio stood at 3.4% with a impairment ratio of 6.7%. As a result, the mortgage NPL coverage ratio remained at 34.8% in September 2026. For more information on credit risk and asset quality, see Section 8: Risk. Good performance in brokerage fees for mutual funds and other major products. Net commissions remained stable in the nine months ended September 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 activity (cards and payments) with greater competition in the payments market in Chile. With this, the recurrence ratio (total net commissions divided by structural support expenses) reached 60.8% YTD. 38


 
Commissions per product: Financial accounting information The evolution of commissions per product was as follows: YTD % change Quarterly % change Ch$ million Sept-26 Sept-25 Sept-26/ Sept-25 3Q26 2Q26 3Q25 3Q26/ 3Q25 3Q26/ 2Q26 Card fees 107,904 109,829 (1.8%) 33,959 35,560 34,696 (2.1%) (4.5%) Payments 59,653 77,209 (22.7%) 16,949 20,017 26,938 (37.1%) (15.3%) Asset mgt & Insurance 122,795 108,668 13.0% 42,234 40,573 39,249 7.6% 4.1% Accounts and collections 107,595 107,332 0.2% 36,191 35,779 34,989 3.4% 1.2% Others 28,828 38,104 (24.3%) 1,120 9,461 8,577 (86.9%) (88.2%) Total commissions 426,775 441,142 (3.3%) 130,453 141,390 144,449 (9.7%) (7.7%) Brokerage fees for mutual funds and insurance increased 13.0% in 9M26 compared to the same period in 2025, 7.6% compared to 3Q25, and 4.1% QoQ. This growth reflects increased demand, driven by an expanding client base and greater use of online platforms for purchasing products and services. Mutual fund fees maintained their momentum, as clients sought higher returns. In insurance brokerage, the increase compared to 9M25 is explained by higher fees for non-loan-related insurance, such as life and auto insurance. Compared to 2Q26, demand also grew for insurance associated with mortgage and consumer loans. Current account and collection fees increased by 0.2% in 9M26 compared to the same period in 2025 and by 3.4% compared to 3Q25, primarily due to higher account administration fees, in line with the expansion of our customer base. Account openings continued to grow during the quarter, reaching a market share of 20.4% and more than 3.3 million accounts as of July 2026. Current account and collection fees increased by 1.2% QoQ, also driven by higher insurance collections and money orders. Credit and debit card fees decreased by 1.8% in the first nine months of 2026 compared to the same period in 2025, by 4.5% QoQ, and by 2.1% compared to the third quarter of 2025. The decline is mainly due to lower transaction volume, associated with reduced consumer spending. To a lesser extent, higher spending by loyalty programs during the quarter also contributed, driven by campaigns that awarded more airmiles to customers who purchased more banking products. Payment fees are primarily related to the activity of Getnet, the bank's acquiring business. In 9M26, these fees contracted due to a more competitive environment, following strong growth in 2025. Other fees decreased by 24.3% in the first nine months of 2026 compared to the same period in 2025, primarily due to increased spending on guarantee services provided by multilateral development organizations seeking to promote the growth of certain portfolios. This was partially offset by improved performance in fees for prepayment of commercial loans and fees generated from financial advisory services related to client debt restructurings. 39


 
Net financial results income increased by 0.6% in 9M26.

In 3Q26, this line generated a profit of $61,098 million, a 24.8% decrease compared to 3Q25 and a 13.2% decrease compared to 2Q26. This performance is mainly explained by higher gains in the valuation of derivative contracts in the financial assets and liabilities for trading line and by higher portfolio sales in previous quarters of 2026. This was partially offset by a foreign exchange loss due to the depreciation of the Chilean peso and lower portfolio sales in the third quarter. For a better understanding of these lines, they are presented by business area in the following table: Net financial results by business: Non-accounting financial information YTD % Change Quarterly % Change Ch$ million Sept-26 Sept-25 Sept-26/ Sept-25 3Q26 2Q26 3Q25 3Q26/ 3Q25 3Q26/ 2Q26 Client 194,592 195,450 (0.4%) 62,502 62,627 66,103 (5.4%) (0.2%) Non-Client (1) 22,170 19,917 11.3% (1,404) 7,779 15,098 (109.3%) (118.0%) Total net financial transactions 216,762 215,367 0.6% 61,098 70,406 81,201 (24.8%) (13.2%) 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 customer treasury services reached a profit of $194,592 million as of 9M26 and a profit of $62,502 million in 3Q26, a decrease of 0.4% YoY and 5.4% compared to 3Q25 and 0.2% compared to 2Q26 due to lower demand for market making products. Non-customer treasury totaled a gain of $22,170 million in 9M26, mainly explained by the sale of commercial portfolio and ALCO and better hedging results in the first semester of the year and which did not show the same behavior in 3Q26. 40


 
Efficiency of 33.0% in 9M26 with operating expenses contracting YoY. The Bank's efficiency ratio reached 33.0% as of September 30, 2026, an improvement from 35.9% in the same period of the previous year. Quarterly, the efficiency ratio was 36.1% in 3Q26 compared to 30.8% in 2Q26 impacted by the lower operating income in the period. Meanwhile, the cost-to-asset ratio decreased to 1.4% in the first nine months of 2026. Operating expenses (which include other expenses) decreased by 4.2% compared to 9M25, primarily due to lower administrative costs. It's worth noting that during the first quarter of 2025, the Bank completed a significant 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 2Q26, operating expenses decreased by 1.4% in 3Q26 and by 4.0% compared to 3Q25, explained by lower spending in the other operating expenses line in the quarter.

Personnel expenses increased by 3.4% in the first nine months of 2026 compared to the same period in 2025, primarily due to salary adjustments in line with inflation and higher severance payments, in the context of a 4.6% reduction in staff and a 5.2% decrease in the number of branches. Compared to the second quarter of 2026, personnel expenses decreased by 0.9%, mainly due to lower compensation in line with the reduction in staff during the quarter. This was partially offset by higher severance payments. Compared to the third quarter of 2025, personnel expenses increased by 7.0%, explained by salary adjustments for inflation and higher severance payments based on years of service. Administrative expenses decreased by 5.5% in 9M26 compared to the same period in 2025 due to lower technology and data processing expenses, largely related to the aforementioned Gravity project. Compared to 2Q26, administrative expenses increased by 3.6% in 3Q26 due to higher data processing expenses. Administrative expenses increased by 2.5% in 3Q26 compared to 3Q25 due to higher data processing and advertising expenses. Depreciation expenses decreased 2.8% in 9M26 compared to the same period in 2025 and 4.3% in the quarter compared to 3Q25, mainly due to lower depreciation of internally developed software and equipment. Compared to 2Q26, depreciation expenses decreased 1.4% QoQ, mainly due to lower equipment depreciation in the quarter. Other operating expenses decreased 31.0% in 9M26 compared to the same period in 2025, primarily due to lower fraud-related expenses. Compared to 2Q26, other operating expenses decreased 28.8% QoQ and 54.5% compared to 3Q25 due to lower restructuration plan expenses. 42

In 3Q26, tax expense decreased 21.0% QoQ and 12.9% compared to 3Q25 due to lower revenues in the quarter. For tax purposes, capital must be adjusted for inflation; therefore, when inflation is high, the effective tax rate tends to be lower. As of September 2026, the effective tax rate was 15.0%. On October 17, 2026, the National Reconstruction and Economic and Social Development Law was published in the Official Gazette, which includes a gradual reduction of the First Category Tax rate from 27% to 23%. As of September 30, 2026, deferred tax assets and liabilities were determined based on the tax regulations in effect at that time. As a result of this legal amendment, the Entity must remeasure its deferred tax assets and liabilities. Based on preliminary estimates, the remeasurement will generate a negative effect of approximately Ch$ 45 billion during the fourth quarter of 2026, of which Ch$ 40 billion will be recognized as an increased expense in profit or loss and Ch$ 5 billion as a charge in Other Comprehensive Income (OCI). 43


 
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. The Bank's expectations for 2027 are based on the macroeconomic scenario projected by our Research team, which considers economic growth of around 3.5%, inflation converging to the Central Bank's 3% target, and the maintenance of the monetary policy rate. This environment should favor greater demand for credit during the coming year. Indicator Initial expectation Key factor Loan growth 6% - 7% Demand reactivation driven by macro environment.

Section 8: Risks Risk management in 3Q26 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. 46

Distribution by economic sector The Bank's portfolio is highly diversified, with no significant exposure to specific industries, which contributes to greater stability and resilience over time. 9.1 % 8.5 % 12.4 % 20.2 % 26.9 % 43.4 % 42.2 % 14.3 % — % Interbank Consumer Mortgage Commercial Social services and other community services Trade Real estate services Agriculture, livestock farming, fishing, forestry, etc. Manufacture Utilities Construction Transport Financial services Telecommunications Mining Oil and natural gas Total portfolio Commercial Portfolio 0 % 20 % 40 % 60 % 80 % 100 % Credit quality of debtors As of September 2026, the NPL rate increased slightly to 3.5%, while the impaired loan ratio rose to 7.4%. While some stabilization was observed in certain indicators during the third quarter, the commercial portfolio continues to reflect some greater deterioration observed in previous years, especially in specific individual exposures. The commercial non-performing loan ratio reached 4.0% in September 2026, while the impaired commercial loan ratio increased from 8.6% in December 2025 to 8.7% at the end of September 2026. Throughout 2026, the mortgage portfolio has reflected the macroeconomic environment, where inflation has surprised on the upside and indicators show a weaker labor market. As a result, the mortgage NPL rate reached 3.1% in December 2025 and 3.4% in September 2026. Meanwhile, the impaired mortgage loan ratio reached 6.3% and 6.7%, 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 deterioration ratio of 5.5% and an improvement in the NPL ratio from 2.5% in December 2025 to 2.3% in September 2026. Over the past few months, significant rainfall has been recorded in various parts of the country. Management is continuously monitoring the evolution of these events and their potential effects on client activity and the different business segments. Accordingly, no material impacts on the loan portfolio or significant changes in the Bank's main risk and asset quality indicators have been observed to date. 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 development of situations related to the El Niño phenomenon and its potential impact on economic activity in certain productive sectors, maintaining prudent and timely management of associated risks. 48

Market risk There are four main market risks that can affect the Bank: exchange rate, inflation, interest rate, and liquidity. Their measurement and control are the responsibility of the Market Risk Management 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. 49


 
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. 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. 50


 
As of September 30, 2026, the Bank's ALAC amounted to Ch$8,699,363 million and corresponded mainly to Level 1 liquid assets, composed mainly of bonds of the Republic of Chile, Central Bank of Chile and United States Treasury. Liquid Assets (Consolidated Ch$ million) Tier 1: Available, 1,740,160 Tier 1: Fixed Income, 6,957,004 Tier 2: Fixed Income, 2,199 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 September 30, 2026, this indicator for Banco Santander Chile stood at 172.3% above the minimum (100%). This reflects the conservative liquidity requirements established by the board of directors through the ALCO committee. Evolution of LCR 171.8% 187.7% 151.4% 177.1% 172.3% Sept-25 Dic-25 Mar-26 Jun-26 Sept-26 51


 
NSFR This indicator is a local regulatory version of the NSFR required by Basel III, which provides a sustainable maturity structure for assets and liabilities, enabling banks to maintain a stable funding profile relative to their operations. As of September 30, 2026, the NSFR stood at 116.9%. Evolution of NSFR 111.0% 115.1% 115.6% 118.2% 116.9% Sep-25 Dec-25 Mar-26 Jun-26 Sep-26 Interest rate risk: banking book For its financial management portfolio (bank book), the Bank has more liabilities than assets exposed to short- term interest rates, resulting in mismatches when interest rate adjustments occur. 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.

VaR trading portfolio In the case of the trading portfolio, risk is estimated and managed using Value at Risk (VaR) limits, which have been maintained within the established risk limits. 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. VAR September 30, 2026 US$ million Consolidated: High 1.99 Low 0.65 Average 1.15 Fixed income investments: High 2.50 Low 0.63 Average 1.70 Foreign currency investments High 0.91 Low 0.10 Average 0.34 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 readjustment 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-earning assets.
