Section 1: Key information Summary of results ROAE 1 of 16 . 6 % in 4 Q 23 2 and 11 . 9 % in 12 M 23 3 , with a solid net contribution from business segments that increases 34 . 7 % . As of December 31 , 2023 , net income attributable to shareholders reached Ch $ 496 billion ( $ 2 . 63 per share and US $ 0 1 . 20 per ADR), decreasing 38 . 6 % compared to the same period last year and with an ROAE of 11 . 9 % . This lower result was mainly due to the impacts perceived in the NIM 4 produced by the deceleration of inflation during the year and higher interest rates that reduced the return on assets in UF and increased the funding costs, respectively . The net contribution of our business segments continues to be very strong, increasing 34 . 7 YoY 5 . Specifically, the Retail Banking segment increased 25 . 6 % YoY with total revenues increasing 22 . 0 % YoY . The net contribution of the Middle - market segment increased 27 . 9 % YoY, with an increase in total revenues of 16 . 3 % YoY . Finally, the net contribution of our Corporate and Investment Banking (CIB) unit grew 65 . 4 % YoY, driven by a 42 . 8 % YoY increase in total revenues . In the fourth quarter of 2023 , net income attributable to bank owners totaled $ 177 billion, increasing 212 . 5 % in the quarter with a quarterly ROAE of 16 . 6 % This increase is mainly due to higher inflation in 4 Q 23 of 1 . 6 % , compared to 3 Q 23 when it was 0 . 3 % . Also, the first cuts in the monetary policy rate during the second half of 2023 are already beginning to take pressure off the cost of funding . 1 . Return on Average Equity. Annualized net income attributable to shareholders divided by average equity attributable to shareholders. 2 The fourth quarter of 2023. 3. Nine months accumulated as of December 31, 2023. 4. NIM: Net interest margin. Annualized net income from interest and readjustments divided by interest earning assets. 5. Year on year, the twelve months accumulated as of December 31, 2023 compared to the twelve months accumulated as of December 31, 2022. 4

Net income from fees increases 22 . 4 % in 12 M 23 , with the recurrence 6 ratio reaching 55 . 3 % . During 12 M 23 , net commissions increased 22 . 4 % YoY due to an increase in clients and greater usage of our products . With this, the recurrence ratio (total net fees divided by total expenses) increased from 42 . 4 % accumulated as of December 2022 to 55 . 3 % accumulated as of December 2023 , demonstrating that more than half of the Bank's expenses are financed with the commissions generated by our clients . In 4 Q 23 , commissions decreased 5 . 2 % Q/Q, mainly because the other commissions line fell due to a quarter with fewer insurance brokerage commissions and lower collections . However, commissions on our main products continue to show good trends . Top 1 in NPS among our Chilean peers The first pillar of our strategy is based on cutting - edge technology and customer - focused processes and products . We are building a bank with strengths in digital channels that already allows digital onboarding in a safe, fast and user - friendly way, offering our Life and Más Lucas accounts for the mass segment and the PYME (SME) Life account and payment services through Getnet for small and medium - sized businesses and entrepreneurs . These initiatives not only encourage our clients to become more digital, they are also managing to increase financial inclusion in these segments and supporting them with transaction services, with the potential to extend the offer of other products and financing options . As a result of all our efforts, our clients are the most satisfied with us . As of December 31 , 2023 our NPS reached 60 points, and our contact center reached 72 points, being recognized as the best in the industry . Our digital channels also continue to be our strength, highlighting the website with an NPS of 73 and the App with 74 points . Solid capital levels with a CET1 ratio of 11.1% and a BIS ratio of 17.6% Our CET 1 ratio remains solid at 11 . 1 % and the total Basel III ratio reaches 17 . 6 % at the end of December 2023 . Risk - weighted assets (RWA) increased 4 . 0 % since December 31 , 2022 and decreased 0 . 9 % Q/Q . We are actively seeking to reduce our market risk - weighted assets through netting and novation of our derivatives portfolio, resulting in a 9 . 2 % decrease this quarter . At the same time, core capital increased slightly by 2 . 9 % Q/Q, mainly due to lower growth in results and 4 . 4 % since December 31 , 2022 , which considers the payment of dividends authorized at the last shareholders meeting in the month of April . Additionally, in January 2024 , the FMC announced the Pillar II charges for six banks in the Chilean system, and we highlight that, on this occasion, they did not assign a Pillar II charge to the Bank . 6 . Recurrence: Net fees divided by operating expenses. 5

We launched Workcafé Inversiones and reached a total of 91 Workcafés in Chile In 4 Q 23 we launched Work/Café Inversiones, a new space open to the community aimed at helping people improve their financial well - being . Clients and potential clients will be able to access specialized advice, talks and workshops on different topics that will help them learn and understand more about investment instruments, the impact of market movements and how to prepare for their various personal projects . Through concrete initiatives such as the opening of this new space, the Bank continues to clearly advance its purpose of helping people progress . This branch is part of our network of 91 Workcafé branches, which includes our Work/Café StartUp and Work/Café Expresso, in addition to our traditional Workcafés . The Work/Café StartUp is an initiative that aims to offer a comprehensive solution to all the needs of entrepreneurs . The Work/Café Expresso are transaction centers with cashier or self - service services, service desk, stampers for card printing and lockers for product delivery, all of the above in Work/Café format, where our clients can carry out their transactions in an environment efficient and secure, providing a better customer experience . As of December, we have opened 5 Work/Café Expresso, with an customer satisfaction (NPS) of 74 . Successful issuance on the Swiss market in January 2024 In January 2024 , the Bank returned to the international market with the successful issuance of a bond in Swiss francs for CHF 225 million (equivalent to US $ 263 million) for a three - year term, achieving a spread of 125 basis points over the reference rate, which is equivalent to a coupon of 2 . 445 % . The results of this transaction reflect the great interest and demand from investors, making it the third largest placement of a Chilean issuer in this market . The previous two also belong to Banco Santander, for CHF 250 million in 2010 and for CHF 300 million in 2014 . This new operation consolidates the excellent reception of Santander Chile in international markets, considering that the entity had not issued new bonds in this market since 2021 . Thanks to this recent instrument, the Bank's position in the Swiss franc market is around CHF 900 million (close to US $ 1 , 000 million), consolidating itself as the second most relevant within the entity's financing diversification strategy, thus reaching around 25 % of the total foreign debt . We made important progress in our Chile First strategy in 2023 • Largest bank in terms of loans and deposits (17.4% market share according to latest information from the CMF). • only Chilean bank included in the DJSI emerging markets. • More than 167,000 people bankerized through the Life y Más Lucas accounts in 2023. • A total of 91 Workcafés in Chile, serving our clients and the community in their different formats. • TSR 7 of 35.8% in 2023, the highest among Chilean banks. • First green bond of JPY 8.000 million equivalent to US$ 50 million to finance green mortgages. • Recognized as the Best Bank in Chile in 2023 by The Banker and Euromoney. • More than US$450 million committed to invest in infrastructure and technology between 2023 and 2026. 7 .

Operating environment All of our operations and substantially all of our customers are located in Chile . Consequently, our financial condition and the results of our operations are substantially dependent on the economic conditions prevailing in Chile . During the months of the last quarter of the year, the economy begins to stabilize, although domestic demand is still weakened . There are specific supply factors that have allowed the activity to present better results in those months . But with the strong decline of the IMACEC in the last month of 2023 (published on February 1 , 2024 ), it follows that the GDP would have closed the year with a variation of - 0 . 2 % , less than the 0 % previously estimated . We estimate that these results, in part, are transitory in nature and, therefore, should be reversed . However, they show an economy that still remains fragile, with a recovery that is not assured . The labor market continues without progress . Job creation has picked up, but concentrated in informal jobs . Formal jobs remain stagnant and the employment rate remains below historical averages . Real wages have tended to rise due to the rapid decline in inflation . Inflation fell sharply in December, wit h a variation of - 0 . 5 % , strongly surprising on the downside (market estimates pointed to - 0 . 1 % an d the last Monetary Policy Rep o rt had a n implicit 0 % ), closing the 2023 CPI at 3 . 9 % , w ell b el o w what wa s projected . I n the coming months, we will continue to see limited variations, although, given the volatility shown by some items wit h high incidence, it cannot be rule d out that relevant su rprise s may occur in any direction . A s of January 2024 the n ew consumer basket begins to govern, wit h changes in the weightings an d adjustments in the methodology for raising some prices . According to our preliminary analyses, the new basket should not introduce a bias to price dynamics going forward . Thus, we estimate that in the coming months inflation will continue to decline and will be around the target towards the beginning of the second quarter, although it could rise again in the second quarter due to base effects and then stabilize again at around 3 % from August onwards . The variation of the UF in 4 Q 23 increased strongly compared to the previous quarter ( 1 . 6 % in 4 Q vs 0 . 3 % in 3 Q), closing the year with a UF variation of 4 . 8 % . We expect that for next year the UF variation will reach 2 . 5 % , the first quarter being lower given the recent December CPI . The last months of the year presented mixed movements in the dollar . We began the quarter with a significant depreciation in the month of October, reaching $ 950 , but after the decision to lower the MPR cuts and suspend the reserve accumulation program, the exchange rate returned to close to its fundamentals (around $ 880 ), to close the year at $ 879 due to the global weakening of the dollar after the Fed's decision that pushed up the prices of currencies throughout the region . At the beginning of the year 2024 , the exchange rate has climbed back to above $ 915 , but we hope that the current decoupling will be corrected, and it would appreciate towards the end of the year to levels close to $ 870 . The monetary policy rate (MPR) reached its maximum of 11 . 25 % in October 2022 . The Central Bank began the rate cut process in July 2023 and has continued with that trend in all its subsequent meetings, closing the year at 8 . 25 % . In 11

2024 , cuts continue with a 100 bp drop at the January 31 meeting, as the Central Bank has room to continue with aggressive MPR cuts as inflation as well as core inflation have fallen rapidly .

Constitutional Convention After the December 2023 referendum where the Chilean population rejected the second proposal for a new constitution for Chile, the current constitution remains valid and there is a political consensus that a new process will not be carried out . Any proposed changes can be made to the current constitution through the processes already established in Congress . 12

13 Tax reform The Chilean Finance Ministry presented a tax reform proposal to Congress in July 2022 , but raised several criticism and doubts from both the private and the political sectors, in particular, regarding those aspects that could impact the country`s competitiveness and investment levels . The proposed reform was rejected on March 2023 . After the rejection of the proposal, the discussion of the reform focused on the mining royalty . A new tax project for mining was proposed and approved in mid - May 2023 . In general, the project establishes a new tax scheme for mining operators that produce more than 50 , 000 metric tons of fine copper per year that considers a 1 % ad - valorem tax on annual copper sales, and a component on the mining margin with rates between 8 % and 26 % according to operating margin . A maximum potential tax burden was set between 45 . 5 % and 46 . 5 % depending on the volume of production . This new tax structure will come into effect as of 2024 and, under the regime, it expects to collect 0 . 45 % of GDP (equivalent to approximately US $ 1 . 350 billion), of which US $ 450 million will be distributed directly to promote the productive development of regions and districts throughout the country . Meanwhile, the government is carrying out a fiscal pact, seeking to modernize the current tax system, prioritize spending, greater transparency of state services and fiscal supervision . As part of this, they hope to encourage investment, productivity and formalization of the economy while closing opportunities for tax evasion . In this context, on January 23 , 2024 , the government presented the Tax Obligation Compliance Project . This bill seeks to raise 1 . 5 % of GDP through 7 thematic axes : i) Modernization of the tax administration and the Tax and Customs Courts ; ii) Control of informality ; iii) Tax crimes ; iv) Aggressive tax planning ; v) New powers for the Taxpayer Ombudsman's Office ; vi) Regularization of tax obligations ; vii) Institutional strengthening and probity . This project will be submitted to Congress during January . Pension reform In November 2022 , the Chilean government presented a new bill for pension reform to Congress . The new proposal creates a Mixed Pension System . It maintains the individual capitalization system and complements it with a contributory pillar with social security logic . The 6 % additional contribution charged to the employer is allocated to social security, whose benefits are distributed among pensioners using social security criteria, better diversifying idiosyncratic risks among people . Also, a new institutional structure is created where public and private entities coexist . The Executive has proposed the creation of the Autonomous Pension Administrator, which will be in charge of the collection of individual and social security contributions, pension payments and other operational functions . In addition, there will be a public institution that, together with private institutions, will take charge of the financial management of the pension funds . People will have the right to choose which type of institution invests the individual capitalization savings . Additionally, all pensions will be paid out as annuities and the programmed withdrawal option will be eliminated . Lastly, the Universal Guaranteed Monthly Pension (PGU) will be increased to Ch $ 250 , 000 /month (US $ 300 ) . This bill has yet to be approved by Congress . On January 24 , 2024 , the Chamber of Deputies approved legislation on this matter, sending the project to the Senate for second processing . Now the initiative must be discussed in the Labor and Finance Commissions of the Upper House . Chamber of Deputies approved the creation of Social Security and its administration, in addition to issues related to

14 the Universal Guaranteed Pension and financing formula . And on the other hand, the new 6 % contribution rate was rejected along with the creation of a public institution for the financial management of the funds . All in all, the financial system welcomes this advance since it will imply greater savings at the country level . Pillar 2 – Basel III Implementation In the context of the implementation of Basel III in Chile, the FMC on December 12 , 2023 put out for consultation adjustments to the regulations on capital requirements for banks, referring to the component known as Pillar 2 . In this new cycle, the FMC is evaluating and quantifying the non - traditional material risks to which each bank is exposed, to determine whether or not the application of regulatory capital charges through the use of Pillar 2 is appropriate . The risks covered in Pillar 1 , covers the Traditional risks, considered to be : credit, market and operational risks . And the non - traditional risks that Pillar II seeks to cover are (and which depend on the business model of each bank) : the market risks of the banking book ; credit concentration ; reputational ; strategic ; cybersecurity ; geopolitical, climatic, among others . Subsequently, on January 17 , 2024 , the FMC applied the current regulations on additional capital requirements according to Pillar II, where the Council resolved to apply said requirements to the following institutions : Banco Bice, Banco BTG Pactual Chile, Banco Consorcio, Banco de Chile, Banco Estado, Banco Internacional, Banco Security, HSBC Bank (Chile) and Scotiabank Chile . The previous decision is based on the capital self - assessment process through the Effective Equity Self - Evaluation Report (IAPE) carried out annually by all banks in the month of April . In this report, it is the banks themselves who determine their internal objective of effective equity necessary to cover their material risks over a horizon of at least three years . And in addition, the IAPE corresponding to the year 2023 also considers the risks for which there is no measurement standard, such as market risk in the banking book and credit concentration risk . Finally, these new charges respond entirely to the risk of credit concentration and market risk in the banking book . For this last risk, the FMC has proposed changing the definition of a typical bank and eliminating the 15 % CET 1 threshold regarding the impact on economic value . This discussion will take place in the coming months so Pillar II charges are likely to change for all banks in the coming years . Interchange fees In February 2023 the Committee for the Fixing of the Interchange Rate limits proposed new limits to the interchange fees . These were approved in April 2023 , and their implementation will be gradual . In 18 months (Oct - 24) In 6 months (Oct - 23) Current rate Type of card 0.35% 0.5% 0.6% Debit 0.80% 1.14% 1.48% Credit 0.80% 0.94% 1.04% Prepaid

15 New Fogape Apoya Chile (Fogape Support Chile) New state guarantees for micro, small and medium companies for working capital, investment and refinancing of debt . This program is available until December 31 , 2023 and could potentially support up to 60 thousand companies who are in vulnerable sectors such as tourism, cultural activities, agriculture and construction . New Fogaes Banco Santander Chile will participate in the new FOGAES loans . The objective of the new special guaranteed fund (FOGAES), launched on April 5 by the government, is to support families in obtaining a mortgage loan for the purchase of their first home, within the framework of the Government's measures for security economic situation of families in the country . This will also contribute to the reactivation of the sector . The Fogaes Law involves an initial fiscal contribution of 50 million dollars and is made up of two programs that will last 12 months : the Housing Support guarantee program and the construction support program . The Housing Support program is intended to facilitate access to mortgage loans to buy a home for the first time . This program establishes that financial institutions can provision between 80 % and 90 % of the value of the home with the same parameter used for 80 % of the value . With the above, it aims to reduce the cost of financing granted by the financial institution . The Fogaes Construction Support program is intended to support access to financing for companies in the real estate and construction sectors. The requirements to access the construction support program are: ● Have annual sales over UF100,000 and up to UF1,000,000. ● Have at least one transfer corresponding to an activity on the list defined in the regulations. New regulation for consumer provisions During 2022 , the FMC published a draft for a new standardized consumer loan provisioning model for banks . The FMC estimated an impact for the entire industry of about US $ 1 , 000 million and the Bank estimated an impact of expense of between Ch $ 100 , 000 million to Ch $ 150 , 000 million . In October 2023 , the FMC published a second draft for consultation for the same model, estimating an initial impact of US $ 487 million for the entire system . We estimate that the impact of this regulations will be Ch $ 90 , 000 million for the Bank . According to what is written by the FMC, it can be covered with voluntary provisions already established in previous periods . Regulation and supervision In Chile, only banks may maintain checking accounts for their customers, conduct foreign trade operations, and, together with regulated non - banking financial institutions, such as Cooperatives, accept time deposits . The principal authorities that regulate financial institutions in Chile are the Financial Market Commission ( FMC) and the Central Bank .

20 SMEs: Through digital onboarding and initiatives such as Getnet, offering solutions for your businesses, we have managed to grow our customer base by 19 . 1 % in 2023 . Retail Banking loans grew 7 . 3 % YTD and 3 . 1 % compared to the previous quarter . Mortgage loans continued to increase 2 . 5 % QoQ and 8 . 5 % YoY, higher than the increase in the UF, which increased only 1 . 6 % QoQ and 4 . 8 % YoY, indicating that we are beginning to see that the origination of new mortgages is beginning to grow . On the consumer side, the increase of 6 . 0 % YTD and 2 . 9 % QoQ, are driven mainly by credit cards loans that grow 12 . 4 % YoY . Finally, SMEs have decreased by 1 . 8 % YTD but with an increase in the quarter of 2 . 4 % . We are beginning to see a reactivation in this segment after several periods of contraction due to SMEs accessing Fogape loans during the pandemic, which led to a drop in demand for new SME loans for some periods . Now that the Covid Fogapes are over, demand for new loans is increasing . On the other hand, total deposits in this segment increased 2 . 5 % YTD and 2 . 2 % QoQ due to the increase in the customer base and checking accounts, including accounts in MX, in addition to the attractive rates on time deposits . Results: The net contribution of retail banking increased 25 . 6 % YoY . The margin increased 22 . 3 % YoY due to a better mix of funding and loan growth . Fees in this segment increased strongly by 20 . 4 % YoY, driven by card fees due to greater usage and the increase in the client base, as well as the fees generated by Getnet . Provisions increased 56 . 7 % YoY, without including additional provisions, due to the growth of the portfolio in the year, slowing economic growth and the normalization of asset quality of our retail loans after historically low levels of non - performing loans due to the increase in liquidity of our clients in recent periods . Operating costs increased in a controlled manner by 4 . 1 % YoY as the Bank continues its digital transformation, generating greater operating efficiencies . Compared to 3 Q 23 , the net contribution of retail banking increased 5 . 8 % QoQ . The margin increased by 1 . 6 % QoQ mainly due to the higher spreads earned on demand deposits and a greater volume of current accounts . Commissions in this segment decreased 13 . 6 % in the quarter, mainly as a result of lower commissions for insurance brokerage for products not related to loans as well as lower commissions for collections and prepayments of consumer loans . Provisions increased 4 . 1 % QoQ mainly due to the higher consumer provision expenses due to an increase in NPLs on these loans in line with the labor market . The operating costs increased 0 . 9 % QoQ, mainly due to greater publicity and marketing costs related to the products in this segment .

Deposits decreased 9 . 5 % YTD and 3 . 5 % QoQ, due to the high levels of liquidity of these clients in previous years, which in 2023 have been almost completely drained . The main strategic objective of this segment is to focus on the client's total profitability, in credit and non - credit activities . Sustainable financing has also been a focus with US $ 407 million in sustainable loans disbursed during 2023 . Results: Net contribution from the Middle Market increased 27 . 9 % YoY, with an increase in total revenues of 16 . 3 % due to a 18 . 0 % growth in net interest income as a result of a better loan and the decrease in deposits in the period . Additionally, commissions increased by 3 . 7 % in line with the greater activity of clients in payments and other products, and compensated by lower fees from factoring and guarantees . Provisions in this segment decreased 14 . 8 % YoY due to lower growth in loans and a better behavior in some industries such as construction and real estate when compared to 2022 , despite greater risks in sectors such as agriculture that we saw affected with the intense rains and floods resulting from the “El Niño phenomenon”, which mainly affected the central regions of Chile where there is a lot of crops . Expenses remain stable as a result of the efficiencies generated by technological projects . In the quarter, the net contribution of Middle Market decreased 6 . 1 % QoQ, due to lower provision expense of 35 . 3 % QoQ as a result of lower provisions made in the quarter compared to 3 Q 23 when we reclassified some clients who graduated to the individual provisioning model .

22 Corporate Investment Banking (CIB): Accounting financial information Business activity: The loan portfolio in the CIB segment increases by 3 . 3 % YTD due to an increase in factoring loans and foreign trade loans and decreases 1 . 5 % QoQ due to exchange rate effects . Deposits increased 24 . 4 % YTD and a 6 . 2 % QoQ due to higher demand for time deposits in CLP considering the higher rates . Results: Total income from this segment increased 65 . 4 % YoY . Net income from interest and readjustments increased 73 . 0 % YoY due to a better margin from its financing sources due to the increase in current account balances . Also noteworthy is the year - on - year increase in fees of 35 . 3 % due to a better performance from financial advisory and financial brokerage and also greater customer treasury income of 17 . 3 % YoY in line with this segment Dz s focus on non - lending income . Regarding provisions, during the quarter there was a release in provisions due to the increase in loans with good payment behavior and a decrease in non - performing loans . Expenses increased 4 . 3 % YoY due to higher amortization of technology and administrative costs . In the quarter, CIB's net contribution fell 9 . 9 % as a result of higher provisions in the quarter after a release in 3 Q 23 and an increase in expenses related to the amortizations of technological projects and administrative costs, offset by higher commissions due to greater financial advice in the quarter and a slight increase in interest income and readjustments due to a better spread and greater volume of checking accounts in the quarter .

23 Corporate center/ Financial Management: Accounting financial information: Results: The Bank's results from corporate activities and ALM contributed with a loss of Ch $ 924 billion to results in the nine - month period ended December 31 , 2023 . This was mainly due to a lower margin . During the period we received lower income from interest and readjustments due to an increase in the cost of funding managed by the ALCO due to the increase in short - term rates and the lower carry earned over the portion of the held to collect investment portfolio of Central Bank bonds held as collateral against the FCIC financing lines that were offered to banks during the pandemic to keep loan growth flowing . Both the collateral and the FCIC lines come due in 2024 . Compared to 2 Q 23 , the net loss of the corporate center decreased 48 . 4 % QoQ due to a better result from net income from interest and readjustments due to higher inflation and an improvement in the cost of funding in the quarter as a consequence of the MPR rate cuts .

The clients included in each business segment are constantly revised and reclassified if a client no longer meets the criteria for the segment, they are in. Therefore, variations of loan volumes and profit and loss items reflect business trends as well as client migration effects. The Middle market segment's loan portfolio increases 1 . 5 % YTD, mainly driven by positive conversion gains on dollar - denominated loans against the depreciation of the Chilean peso of 2 . 9 % in 2023 , while in 4 Q 23 , the loan book decreased 0 . 5 % with the Chilean peso appreciating 1 . 7 % compared to 3 Q 23 , mainly affecting our import and export clients . Loans in the CIB segment increased 3 . 3 % YTD influenced by greater demand for factoring and foreign trade in addition to the effect of the exchange rate on loans in dollars . The decrease of 1 . 5 % QoQ is mainly explained by the effect of the appreciation of the Chilean peso in the quarter . Retail banking loans grew 3 . 1 % QoQ and 7 . 3 % since December 31 , 2022 , driven by growth in mortgages . In recent periods, the origination of new mortgage loans has decreased due to high inflation and rates, however, in the second half of the year mortgage loans once again grew stronger than inflation, reaching a growth of 2 . 5 % QoQ and 8 . 5 % from December 31 , 2022 in the way that clients adjust to market conditions .

Consumer loans increased 2 . 9 % QoQ and 6 . 0 % YTD . Between the end of 2019 and 2021 credit card loans decreased 7 . 0 % as clients reduced large purchases such as travel and hotels which fuels credit card loans . At the same time many clients paid off credit card debt with the liquidity obtained from government transfers and pension fund withdrawals . At the end of 2022 , as household liquidity levels returned to normal and holiday travel resumed credit card loans began to grow again . In the last quarter we have seen an acceleration of credit card loans, mainly related to the increased use of cards and seasonality . As for the SME loans, after several quarters with a contraction in this portfolio, growth is beginning to normalize . During the pandemic, our SME clients had access to Fogape programs with a state guarantee . As clients are finishing paying their debt and also thanks to the increase in SME clients through checking accounts and Getnet, the demand for credit in this segment is reactivating . Given the above, the SME segment portfolio increased 2 . 4 % QoQ and decreased 1 . 8 % YTD .

S . treasuries . During the quarter, the Bank began to make use of the Liquidity Deposit Program announced by the Central Bank in September 2023 . This program has the objective of facilitating the payment of the FCIC to banks . This instrument is at a floating MPR and matches the date of the first payment of the FCIC (April 1 , 2024 ) . By regulation, this instrument must be recorded at amortized cost in the HTM portfolio . Given the above, the Bank began to replace part of the Central Bank papers that were in the portfolio available for sale (mostly PDBCs) with Liquidity Deposits, explaining the variations in the quarter of these portfolios . As of December 31 , 2023 , the Bank has invested $ 3 , 392 , 609 million in this instrument . The rest of the HTM portfolio is composed of Central Bank bonds that we had previously set aside as collateral for the utilization of the FCIC . At the end of December 2023 , the total HTM portfolio have a fair market value of Ch $ 7 , 927 , 729 million . 25

Calculated according to Chilean regulations. The last increase by the Central Bank was in October 2022 where the monetary policy rate (MPR) reached 11 . 25 % , closing the cycle of increases . The increase in the rate and the prolonged maintenance of this high level had a direct impact on our funding cost . The downward cycle began with a first cut of 100 bp at the end of July and five consecutive rate cuts with the MPR finishing 2023 in 8 . 25 % . The Bank's total deposits increased 2 . 9 % QoQ and 9 . 6 % YTD . The increase was driven by time deposits that increased 24 . 3 % YTD, mainly in the CIB segment, because high rates led our clients to switch to more attractive deposits explaining the decrease of 3 . 9 % YTD of demand deposits . The growth in the fourth quarter is due to both time deposits and demand deposits with our clients maintaining more liquidity for the end of the year . Our clients' investments through mutual funds intermediated by the Bank also grew in the quarter, reaching an increase of 5 . 4 % QoQ and 25 . 5 % YTD . The bonds increased 1 . 1 % QoQ and 9 . 8 % YTD . During 2023 , the Bank has placed bonds for UF 7 . 7 million, CLP $ 424 , 400 million, US $ 30 million and JPY $ 25 , 500 million, taking advantage of attractive opportunities in the different fixed income markets at a national and international level . In addition to the above, in mid - October the Bank placed its first green bond under its ESG Framework which incorporates ESG criteria focusing on the green mortgage product . The objective of the transaction is to refinance or finance new operations of this product, which is offered by the Bank for the purchase of homes, based on energy efficiency certifications existing in the industry, and which benefits clients with a preferential rate . This is the first green bond with use of funds for green mortgages in the country . The instrument was placed privately to a Japanese investor with the advice of Daiwa Securities Capital Markets, for an amount of JPY 8 , 000 million, equivalent to US $ 53 million, for a term of two years and with a rate of 0 . 845 % . Additionally, in the first days of 2024 , the Bank issued a senior bond for a total of CHF 225 million in the Swiss market with a term of 3 years and a rate of 2 . 445 % . The Bank's Liquidity Coverage Ratio (LCR), which measures the percentage of liquid assets over net cash outflows, as of December 31 , 2023 , was 212 . 2 % , well above the minimum . As of the same date, the Bank's Net Stable Funding Ratio

27 (NSFR), which measures the percentage of illiquid assets financed through stable funding sources, reached 106.5%, also well above the current regulatory minimum established for this index.

Compared to December 31 , 2022 , total equity grew by 6 . 0 % due to a lower loss in valuation accounts, which decreased by 96 . 9 % in the period due to a better result from inflation hedges by decreasing inflation breakeven levels . This was offset by the dividend payment approved by the ordinary shareholders meeting in April where the distribution of 60 % of 2022 profits was agreed and lower net income in 2023 compared to 2022 .

We are actively seeking to reduce our market risk - weighted assets through netting and novation of our derivatives portfolio, resulting in a 9 . 2 % decrease this quarter . At the same time, core capital increased by 2 . 9 % QoQ mainly due to lower growth in results and an increase of 4 . 4 % YTD which considers the payment of dividends authorized at the last shareholders meeting in the month of April . The Bank's ROAE was 16 . 6 % in 4 Q 23 compared to 5 . 4 % in 3 Q 23 , due to greater inflation in the quarter and the rate cuts that improved our margin . The accumulated ROAE 2023 is 11 . 9 % .

Interest expense divided by the sum of interest bearing liabilities and demand deposits. 4. Net interest income divided by average interest earning assets. 5. Inflation measured as the variation in the UF in the period. Year to date net interest income and readjustments (NII) as of December 2023 decreased by 29.8% compared to the same period in 2022. This decrease in NII was mainly due to lower inflation in the period, a higher funding cost caused

30 by a higher MPR and to a lesser extent by our financial investments held to maturity that are at a fixed rate . The above is partially offset by a higher spread earned on deposits . Net income from readjustments decreased 62 . 0 % in 12 M 23 compared to the same period in 2022 , given that the variation in the UF reached 4 . 8 % in 12 M 23 compared to 13 . 3 % in the same period in 2022 . The UF GAP is significantly lower in 12 M 23 compared to 12 M 22 , decreasing 21 . 4 % , in line with lower inflation expectations . The Bank has a shorter duration of interest - bearing liabilities than interest - bearing assets, so our liabilities recognize the change in prices more quickly than our assets . After the rapid rise in the MPR that began in mid - 2021 and continued throughout 2022 , the Central Bank began to cut the MPR in July 2023 from 11 . 25 % , with five successive cuts to reach 8 . 25 % in December 2023 . This has produced a rapid recovery in net interest income, increasing by 23 . 3 % in 12 M 23 compared to 12 M 22 . Despite the above, the effect of lower inflation has been significantly greater, decreasing the NIM from 3 . 3 % as of December 31 , 2022 to 2 . 2 % as of December 31 , 2023 . During the third quarter of 2023 , the Central Bank began to cut the MPR from 11 . 25 % to 10 . 25 % at the end of July to 9 . 50 % in September . Given this, net interest income increased by 3 . 9 % in 9 M 23 compared to 9 M 22 . Despite the above, the effect of a lower inflation has been significantly greater, decreasing the NIM from 3 . 7 % as of September 30 , 2022 , to 2 . 0 % as of September 30 , 2023 . In 4 Q 23 , total net income of interest and readjustments increased by 79 . 6 % QoQ and 37 . 0 % compared to 4 Q 22 and the NIM for 4 Q 23 increased from 2 . 2 % in 4 Q 22 to 1 . 6 % in 3 Q 23 to 2 . 9 % in 4 Q 23 . The above responds to the fact that, first of all, the variation in inflation measured by the variation of the UF was 1 . 6 % in 4 Q 23 , much higher than the 0 . 3 % in 3 Q 23 , however lower compared to 2 . 5 % in 4 Q 22 , explaining the 524 . 5 % increase in net income from readjustments in 4 Q 23 compared to 3 Q 23 and the 13 . 2 % decrease compared to 4 Q 22 . When compared to 4 Q 22 , the GAP UF has increased 25 . 7 % as a result of less favorable terms in the inflation hedge market in 2023 , and which has remained stable compared to 3 Q 23 . Secondly, the cuts in the monetary policy rate are already producing a better funding cost, which decreases from 7 . 1 % in 4 Q 22 to 6 . 6 % in 3 Q 23 to 6 . 5 % in 4 Q 23 . Our time deposits represent 31 . 6 % of our funding, and in general these deposits take the new rate between 30 and 60 days . The swap of the FCIC at a variable rate represents 11 . 9 % of our funding and therefore with each rate reduction the funding cost improves (an immediate effect since the derivative takes the new rate on the same day the MPR is lowered) . Given the above, net interest income increases 93 . 6 % compared to 4 Q 22 and 32 . 0 % compared to 3 Q 23 . We estimate that the Central Bank will continue to cut the rate during 2024 , with the average MPR around 6 . 1 % . It is important to consider that 4 Q 23 inflation will not be repeated during 2024 , so we estimate a normalization towards 3 % annually . With this scenario, we estimate that our NIM for 2024 will begin weaker than the last quarter of 2023 but as 2024 progresses it will recover to reach levels of 3 . 0 % to 3 . 5 % for the full year .

Annualized provision expense divided by average loans. 2. Balance sheet provisions include additional provisions over non - performing loans During the Covid - 19 pandemic, asset quality benefited from state aid and withdrawals from pension funds, which produced a positive evolution of these during that period, later normalizing in line with the economy and the drainage of excess liquidity from households . More recently, the behavior of our clients is reflecting the state of the economy and the labor market, where delinquencies are slightly higher than usual . Given the above, in 4 Q 23 , the non - performing loan ratio (NPL) increased from 1 . 8 % in 4 Q 22 to 2 . 3 % in 3 Q 23 and 4 Q 23 with data for 4 Q 23 below the rising trend due to a calendar effect in the quarter . The impaired portfolio ratio increases from 4 . 8 % in 4 Q 22 to 5 . 5 % in 3 Q 23 and 5 . 6 % in 4 Q 23 . Finally, the expected loss ratio (provisions for credit risk divided by total loans) remains more stable, increasing to 2 . 8 % in 4 Q 23 , from 2 . 7 % in 4 Q 22 as a result of higher provisions made in recent periods . The expense for net credit losses totaled Ch $ 473 , 593 million in the twelve - month period ended December 31 , 2023 , an increase of 27 . 7 % compared to the same period in 2022 and in the same line, the cost of credit goes from 0 . 98 % at the end of December 2022 to 1 . 20 % in 2023 .

32 In the quarter, the expense for credit losses increased 0 . 5 % Q/Q as a result of an increase in recoveries of 9 . 8 % and a decrease in the creation of special provisions for credit risk of 48 . 1 % Q/Q T Finally, the expense of provisions for credit risk for banks and loans and accounts receivable from clients grows 3 . 5 % explained by the acceleration of consumer loans, particularly credit cards in the quarter . With these results, the cost of credit in 4 Q 23 remained stable at 1 . 20 % in 4 Q 23 . The NPL portfolio coverage ratio (which includes the voluntary provisions of Ch $ 293 billion assigned by the Board of Directors between the 2020 - 2022 and Ch $ 6 billion due to the requirement of our regulator) decreased from 185 . 3 % in 4 Q 22 to 157 . 3 % in 4 Q 23 and remained stable compared to 3 Q 23 .

This is in order to cover the expected increase in consumption provisions as a result of the new standardized provision model that the CMF is proposing and which, to date, has not yet been approved . Considering the above, consumer loan provision expenses decreased 3 . 4 % in 12 M 23 compared to the same period in 2022 and 49 . 5 % in 4 Q 23 compared to 4 Q 22 . The consumer NPL ratio increased from 1 . 6 % in December 2022 to 1 . 9 % in September 2023 to 2 . 1 % in December 2023 . The increase is mainly related to the liquidity levels of households that have already returned to pre - pandemic levels added to a weaker economy . Given the above, the total impaired consumer ratio increased, going from 3 . 4 % in December 2022 to 4 . 5 % in September 2023 and 4 . 9 % in December 2023 . This deterioration and the growth of 10 . 5 % of credit card loans in 4 Q 23 produced an increase in consumer provisions of 11 . 4 % compared to 3 Q 23 and the consumer NPL coverage ratio decreased from 467 . 3 % in September 2023 to 413 . 8 % in December 2023 . Commercial loan provision expenses increased 703 . 5 %% in 12 M 23 due to the transfer of voluntary provisions from commercial to consumer which produced a release of commercial provisions in 4 Q 22 . Compared to 3 Q 23 , commercial loan provisions increased 7 . 8 % while the commercial NPL ratio increased from 2 . 5 % in December 2022 to 3 . 0 % in September 2023 to 3 . 2 % in December 2023 the same as the impaired commercial ratio, which increases from 7 . 0 % in 4 Q 22 to 7 . 7 % in 3 Q 23 and then shows a slight improvement to 7 . 6 % in 4 Q 23 . This mainly responds to a more challenging macroeconomic environment for companies, high rates and slowing activity . On the other hand, the commercial NPL coverage ratio decreases from 173 . 6 % in December 2022 to 146 . 1 % in September 2023 and 137 . 1 % in December 2023 .

33 Provision expenses for mortgage loans decreased 1 . 2 % in 12 M 23 compared to the same period in 2022 and 33 . 3 % Q/Q and 68 . 1 % compared to the same quarter of the previous year . This is explained by the evolution of the mortgage NPL ratio, which in December 2022 was 1 . 2 % , then worsened to 1 . 6 % in September 2023 and then improved to 1 . 3 % . The impaired mortgage ratio increased from 2 . 7 % in December 2022 to 3 . 4 % in September 2022 and 3 . 7 % in December 2023 , indicating that clients are renegotiating their credit . With the above, the mortgage NPL coverage ratio rises from 64 . 4 % in December 2022 and 62 . 3 % in September 2023 to 74 . 1 % in December 2023 . For more information on credit risk and asset quality see Section 6 : Risk .

With this, the recurrence ratio (total net commissions divided by total expenses) increased from 42 . 4 % accumulated as of December 2022 to 55 . 3 % accumulated as of December 2023 , demonstrating that more than half of the Bank's expenses are financed with the commissions generated by our clients .

Revenue from client treasury services reached a profit of Ch $ 245 , 926 million as of 12 M 23 , an increase of 12 . 2 % compared to the same previous period, and an increase of 9 . 0 % in 4 Q 23 compared to 4 Q 22 and stable compared to 3 Q 23 . These improved results reflect greater client demand for treasury products such as spot currency purchases, forward contracts and derivatives due to high market volatility and increases in the monetary policy rate . Non - customer treasury totaled Ch $ 54 , 313 million, increasing considerably compared to the period of the previous year . In 12 M 22 , negative non - customer treasury results were recorded due to a loss from the management of Financial Management liabilities, which was not repeated in 2023 . The decrease in non - customer income in 4 Q 23 compared to 3 Q 23 is mainly due to negative results in the inefficiency of hedges of the portfolio managed by Financial Management and the sale of portfolios in the period . Operating expenses decreased 5.4% in 12M23, demonstrating the solid cost control in the year Operating expenses decreased 5 . 4 % in 12 M 23 compared to the same period in 2022 demonstrating solid cost control in the quarter as the Bank continues to improve its productivity levels .

Section 6: Risks Risk management in 4 Q 23 has focused on preparing our risk structure for an expected slowdown in economic activity and the labor market . Credit risk Estimation of expected loss : The estimation of provisions is based on models of expected loss, in line with Chapter B 1 of the FMC's Accounting Standards Compendium . The loan portfolio is divided into individually and collectively analyzed loans . Within each group, there are different provision models for consumer loans, mortgages, and commercial loans . The provisions of the majority of loans are determined, in simple terms, through the following formula of expected loss . Provisions for individual assessments According to the FMC, an individual assessment of commercial debtors is necessary for companies that, due to their size, complexity, or level of exposure, must be analysed in detail . The debtors' analysis is primarily focused on their creditworthiness . Therefore, they are classified in the corresponding risk category and by their respective credit transactions and contingent loans before being assigned to one of the following portfolio categories : Normal, Substandard, and Impaired portfolio . For this assignation, several risk factors are considered : the industry or economic sector, their business, partners and management's situation, financial situation, payment ability, and payment performance . Thus, the portfolio assignations are : ● Normal Portfolio : it considers debtors whose payment ability enables them to meet their obligations and commitments and in which there is no foreseeable alteration regarding their economic and financial situation . The classifications assigned to this portfolio are categories from A 1 to A 6 . ● Substandard Portfolio : it includes debtors with financial difficulties or significant deterioration in their payment ability and of which there is reasonable doubt concerning their future reimbursement of the principal and interests within the contractual terms, displaying a limited ability to meet short - term financial obligations . The classifications assigned to this portfolio are categories from B 1 to B 4 . ● Impaired Portfolio : it includes debtors and related loans where recovery is considered remote, as they display a reduced or null repayment capacity . This portfolio encompasses debtors who have stopped paying their 40

loans or show clear signs they will stop paying, as well as those who require forced debt restructuring, reducing the due obligation or delaying their principal repayment or interests ; and any other debtor who is beyond 90 days overdue in their payment of interests or principal . The classifications assigned to this portfolio are categories from C 1 to C 6 . As part of the individual assessment of debtors, the Bank classifies them into the following categories, assigning them a percentage for the probability of default and loss given default (severity), which results in percentages of expected loss . To calculate the provisions to cover an impaired portfolio, firstly, an expected loss rate is determined by calculating the amounts recoverable through financial guarantees and deducting the present value of recoveries obtained through collection services after related expenses . Once the expected loss range is determined, the corresponding provision percentage is applied over the exposure amount, which encompasses loans and contingent loans of the same debtor . The provision rates applied over the calculated exposure are as follows : Al l debtors' credits must be maintained in the impaired portfolio until their payment capacity or performance is normalized, regardless of the sanctioning procedures for each credit, particularly those that comply with the conditions of Title II of Chapter B - 2 of the accounting compendium for CMF banks . (Compendium of Bank Accounting Standards or CNC) . 41

42 Provisions for Group assessments Group assessments are appropriate to address a large volume of transactions that have small individual balances belonging to individuals or small companies . To determine their provisions, group assessments require the clustering of debtors with similar characteristics in terms of debtor type and loan commitments in order to determine both the group's payment behaviour and the recovery of defaulted loans, using technically substantiated estimates and prudential criteria . The model used is based on the debtor's characteristics, payment history, outstanding loans, and defaults, among other relevant factors . The Bank uses methodologies to determine credit risk based on internal and/or standard models to estimate the provisions of the group assessment portfolio . This considers commercial loans for debtors that are not assessed individually, mortgage and consumer loans (including instalment loans, credit cards and overdraft lines) . Such methodology allows the Bank to independently identify the portfolio's performance in the year and thus determine the provision required to cover losses manifested within one year starting from the balance date . The customers are segmented according to their internal and external characteristics into clusters or profiles to differentiate each portfolio's risk in a more appropriate and orderly manner (customer - portfolio model) . This is known as the profile allocation method, which is based on a statistical construction model that, through logistic regression, establishes relations between variables – such as default, external performance, and socio - demographic data, among others – and a response variable that determines the client's risk, in this case a default equal or beyond 90 days . After this, common profiles are defined and assigned a Probability of Non Performance (PNP) and a recovery rate based on a historical analysis known as Severity (SEV) . Once the customers have been profiled and assigned a PNP and a SEV in terms of their loan's profile, the exposure of default is calculated . This estimation includes the customer's book value of loans and accounts receivables added to contingent loans, minus any recoverable amount through collateral enforcement (for credits other than consumer loans) . Notwithstanding the above, to constitute provisions concerning commercial and housing loans, the Bank must establish minimum provisions adhering to the standard method set by the FMC for these types of loans . While such standard model constitutes a minimum prudential baseline, it does not relieve the Bank of its responsibility to have its own internal methodologies for determining sufficient provisions protecting this portfolio's credit risk . The impaired portfolio includes all current and contingent loans of those debtors who are more than 90 days past due in the payment of any interest or principal . It also includes debtors who have been granted a loan to refinance a loan more than 60 days past due and debtors who have undergone forced debt restructuring or partial debt forgiveness . On April 27 , 2022 , in the last amendment to the Compendium of Accounting Standards (CNC) for Banks, it was established that the formation of the group portfolio for commercial exposures, other than student loans, associated with the same counterparty, should not pass a threshold of 20 , 000 UF and 0 . 2 % of the group portfolio . The Bank has implemented this modification, generating a net impact of Ch $ 2 , 344 million in higher provisions for credit risk .

44 Credit quality of debtors At the end of December 2023 , the non - performing loan rate remained stable compared to September, in 2 . 26 % and greater than 1 . 8 % as of December 2022 after historically low levels due to greater liquidity of our clients during the pandemic . At the same time, the impaired ratio ended at 5 . 6 % in December 2023 , increasing slightly from 5 . 5 % in September 2023 and 4 . 8 % in December 2022 . The coverage ratio, including additional provisions, reached 157 . 3 % in December 2023 and the expected loss ratio (credit risk provisions divided by total loans) remained stable at 2 . 8 % . In general, the quality of the asset is reflecting the situation that the Chilean economy and the labor market are going through, which has been putting pressure on our clients during 2023 .

46 Market risk There are four significant market risks that may affect the Bank : liquidity, exchange rate, inflation, and interest rate . The measure and control of market risks are the responsibility of Market Risk Management, which is part of the Risk Division . The limits are approved by the various committees in charge, with responsibility falling primarily under the Market Committee and the Asset and Liabilities Committee (ALCO) . The main market risks are also reviewed by the Comprehensive Risk Committee . The Financial and Capital Management areas, as part of the Financial Division, have the following functions, which are supervised and controlled by the ALCO and Risk Management: ● Optimization of the cost of liabilities, seeking the most efficient financing strategies, including the issuance of bonds and bank lines. ● To handle short - and long - term liquidity regulatory limits. ● Management of inflation risk and exposure ● To manage the risk of local and foreign currency rates. ● Capital adequacy and requirements Liquidity risk The Finance Division manages the liquidity risk using a liquid assets portfolio to ensure the Bank always keeps enough liquidity to cover short - term fluctuations and long - term financing while adhering to regulatory internal liquidity requirements . The Financial Management Division receives information from all the business units on the liquidity profile of their financial assets and liabilities, as well as breakdowns of other projected cash flows stemming from future businesses . On the basis of that information, the Financial Management Division maintains a portfolio of liquid short – term assets, comprised mainly of liquid investments, loans and advances to other banks, to make sure the Bank has sufficient liquidity . The business units’ liquidity needs are met through short – term transfers from the Financial Management Division to cover any short – term fluctuations and long – term financing to address all the structural liquidity requirements . The Bank monitors its liquidity position every day, determining the future flows of its outlays and revenues . In addition, stress tests are performed at the close of each month, for which a variety of scenarios encompassing both normal market conditions and conditions of market fluctuation are used . The liquidity policy and procedures are subject to review and approval by the Bank’s Board . Periodic reports are generated by the Market Risk Department, providing a breakdown of the liquidity position of the Bank and its subsidiaries, including any exceptions and the corrective measures adopted, which are regularly submitted to the ALCO for review . The Bank captures demand deposits from Retail, Middle - Market and Corporates, obligations to banks, debt instruments, and time deposits as its main sources of funding . Although most obligations to banks, debt instruments and time deposits mature in over a year, customer (retail) and institutional deposits tend to have shorter maturities and a large proportion of them are payable within 90 days . The short – term nature of these deposits increases the Bank’s liquidity risk, and hence, the Bank actively manages this risk by continual supervision of the market trends and price management . High - quality liquid assets High - Quality Liquid Assets (HQLA) are an essential component in liquidity risk management . They consist of balance sheet assets, mainly comprised of financial investments that are not consigned as collateral, have low credit risk, and have a deep secondary market . According to the Basel III standards, these assets are divided into three levels, with Tier 1 assets being the most liquid and Tier 3 assets being the least liquid .

As of December 31, 2023 the Bank's HQLA amounted to Ch$ 8,048,069 million and corresponded primarily to Level 1 liquid assets, mainly composed of bonds from the Republic of Chile, the Central Bank of Chile, and the US Treasury. Liquid assets (Consolidated Ch$ million) In terms of liquidity, the main metrics that the Bank's Finance Division manages are : 1. Liquidity Coverage Ratio (LCR) 2. Net Stable Finance Ratio (NSFR) LCR Liquidity coverage ratio (LCR), which measures the percentage of Liquid Assets over Net Cash Outflows . As of April 2019 , Chilean banks began reporting their local LCR figures with a minimum level of 60 % in 2020 , 80 % in 2021 and 100 % in 2022 . This indicator is required by the Basel III standards and provides a sustainable maturity structure for assets and liabilities, allowing banks to maintain a stable funding profile in relation to their activities . As of December 31 , 2023 , this indicator for Banco Santander Chile was 212 . 2 % , above the minimum . This is a reflection of the conservative liquidity requirements set by the Board through the ALCO committee . Evolution of the LCR NSFR This indicator is a local regulatory version of the NSFR required by Basel III, which provides a sustainable maturity structure for assets and liabilities, so that banks maintain a stable funding profile in relation to their activities . As of December 31 , 2023 , the NSFR was at 104 . 4 % . Tier 1: Available; 1.969.547 Tier 1: Fixed income; 6.072.282 Tier 2: Fixed income; 6.240 47

Evolution of the NSFR Interest rate risk : Bank book For the financial management portfolio (bank book), the Bank has more liabilities than assets exposed to short - term rates, and from this, mismatches occur when there are rate adjustments . To manage this risk, Banco Santander Chile performs a sensitivity analysis with respect to local and foreign currency . Through simulations, limits are set in relation to the maximum loss that rate movements may 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 through Value at Risk (VaR) limits, where it remained within the established risk limits . Due to the rules established by the Assets and Liabilities Committee (ALCO), the Bank must not have a significant exposure to foreign currencies ; therefore, all exchange rate risk is included in the trading portfolio and is measured and controlled with Value at Risk (VaR) limits . The following table shows the evolution of the Bank's consolidated VaR of the trading portfolio, which includes the exchange rate risk and the interest rate risk of the trading portfolio . December 31, 2023 US$ millions VAR Consolidated VAR 6.81 High 2.61 Low 4.09 Average Fixed - income investments 5.06 High 2.11 Low 3.15 Average Foreign currency investments 5.79 High 0.23 Low 2.20 Average Inflation risk The bank has assets and liabilities that are readjusted according to the variation of the Unidad de Fomento (UF) . In general, the Bank has more assets than liabilities in UF and, therefore, moderate rises in inflation have a positive effect on income from readjustments, while a fall in the value of the UF negatively affects the margin of the Bank . To manage this risk, the ALCO establishes a set of limits on the difference between assets and liabilities denominated in UF . 49

50 Operational risk In general, the indicator of operational risk events on operating income has remained stable and below the system average . As of December 31 , 2023 , operating loss decreased 19 . 0 % compared to the same period last year explained by lower losses from business continuity and lower losses from frauds . Losses from operational risks : Dec - 23/Dec - 22 Dec - 22 Dec - 23 (57.0%) 6,410 2,759 Fraud (16.3%) 6,704 5,611 Labor related 556.0% 116 761 Client / product related 15.4% 221 255 Damage to fixed assets (83.2%) 979 164 Business continuity / systems 56.9% 2,815 4,418 Processing (19.0%) 17,245 13,968 Total

Our long term goal For the purposes of this transformation, we have developed a Chile First initiative plan, where we seek to generate, as Santander Chile, an outstanding financial operation in Chile and within the Santander group, to help our customers, employees, communities and shareholders prosper . Responsible Banking Santander defines two major challenges associated with Responsible Banking : Challenge 1: New business environment Establish a solid culture that allows the development of responsible banking . This culture must be resilient, able to adapt to the demands of a competitive and changing business environment . This implies generating bonds of trust with its interest groups, achieving mutual support . For this, a work culture has been established in Santander that can be summarized in three words : Simple, Personal and Fair . Challenge 2: Inclusive and sustainable growth Generate a broad vision of what inclusive growth means . It must go beyond satisfying customer needs and proactively advance specific social goals . This translates into supporting entrepreneurs in the creation of businesses and jobs, strengthening local economies, advancing financial inclusion, contributing to the education of people and generating social investment programs . In addition, sustainable growth drives the Bank's green financing initiatives .

The six Principles of Responsible Banking establish a global standard definition of what it means to be a responsible bank and are aligned with the UN Sustainable Development Goals (SDGs) and the Paris Climate Agreement. These are: Principles of Responsible Banking Alignment Align the commercial strategy to be consistent with the needs of individuals and the objectives of society, in accordance with relevant approaches at the national and international level, such as the SDGs and the Paris agreement . 55 Impact Set and publish impact goals .

The results of this transaction reflect the great interest and demand from investors, making it the third largest placement of a Chilean issuer in this market. The previous two also belong to Banco Santander, for CHF 250 million in 2010 and for CHF 300 million in 2014. This new operation consolidates the excellent reception of Santander - Chile in international markets, considering that the entity had not issued new bonds in this market since 2021 . Thanks to this recent instrument, the Bank's position in the Swiss franc market is of around CHF 900 million (close to US $ 1 , 000 million), consolidating itself as the second most relevant within the entity's financing diversification strategy, thus reaching around 25 % of the total foreign debt .
