As of June 30 , 2023 Santander Chile employed 9 , 162 people and has 260 branches throughout Chile . For more information on the constitution of our business please see Section 2 of our Management Commentary for 1 Q 22 . 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 . Domestic demand in Chile continues to weaken . The non - mining sectors have fallen significantly, revealing a persistent weakening of consumption and a slowdown in investment . Going forward, we estimate that spending will continue to lose strength in the face of tight financial conditions . For this reason, we corrected downward the estimate for growth for the year to - 1 . 0 % , below the range of the last Monetary Policy Report of the Chilean Central Bank . In 2024 we would return to the trend . The labor market remains weak . Almost zero job creation and destruction of private salaried jobs account for the loss of dynamism in the labor market . The outlook is for this to continue as labor demand has continued to contract . For the same reason, unemployment could rise more in the coming months, exceeding 8 % .

Global inflation continues to drop in the main markets given the normalization of commodity prices . However, underlying components remain elevated . At the local level, the CPI for June ( - 0 . 2 % MoM) surprised on the downside, marking a significant setback in its annual variation ( 7 . 6 % YoY vs . 8 . 7 % in May) with prices falling jn a generalized manner . Going forward, prices will continue to moderate so that the annual variation of the CPI will close 2023 somewhat below 4 % , almost in line with the tolerance range of the Central Bank . The UF variation in 2 Q 23 was 1 . 4 % ( 1 . 3 % in 1 Q 23 ) and we expect a strong drop this year with a UF variation of 4 . 3 % compared to the variation of 13 . 3 % in 2022 . The dollar has remained around $ 800 , but with ups and downs . Following the announcement by the Central Bank of the dollar purchase program for US $ 10 billion at one year in mid - June, the exchange rate tended to depreciate temporarily . Towards the end of 2023 , we maintain our forecast of a range between $ 810 and $ 820 for the exchange rate, based on a dollar that could appreciate somewhat globally if the Fed follows the announced course of action and the price of copper corrects somewhat downwards in line with a greater weakness of the Chinese economy . However, there are no reasons for large deviations of the currency from its current value . The monetary policy rate (MPR) reached its maximum of 11 . 25 % in October 2022 and the Central Bank has maintained that level since then, but we already see an imminent start of rate cuts . Although in its last meeting the Council of the Central Bank maintained the MPR at 11 . 25 % , the decision had two minority votes that opted for a cut of 50 bp . It is highly probable that the start of monetary normalization will begin at the Monetary Policy Meeting in July, with a cut of at least 50 bp . All in all, we expect the MPR to close 2023 at 7 . 25 % .

Constitutional Convention After the referendum was held in September 2022 that resulted in the rejection by voters of the proposed constitution, a new political agreement to start a new constitutional process was announced in December 2022 and approved in January 2023 . The new constitutional agreement includes a defined framework of main ideas that the new constitution should include . This has led to a moderation of internal political uncertainty . There will be a Constitutional council of 50 people plus indigenous representatives, an expert commission of 24 people and a technical commission of 14 people . Both commissions were appointed by the Senate and the Lower house . The timeline of the new constitutional process started in January, with the appointment of the expert committees . Then on May 7 , the council was elected and the new text is expected to be ready by November 2023 . Finally, there will be a referendum with mandatory participation on December 17 , 2023 , to accept or reject this new draft .

Tax reform The Chilean Finance Ministry presented a tax reform proposal that was presented to Congress in July 2022 , but raised several criticism and doubts from both the private and the political sectors, in particular, regarding to those aspects that could impact the country`s competitiveness and investment levels . The proposed reform was rejected on March 2023 . The proposal was based on four legislative initiatives : (i) Restructure income tax system : introduce a semi - dual system for corporate income tax to further de - coupling the taxation of companies from the taxation of shareholders ; increase the tax rates for higher income individuals ; introduce a new wealth tax and a new capital income regime (ii) Reducing tax exemptions : elimination of loopholes that facilitates tax avoidance and strength ability to combat tax evasion ; (iii) Mining royalty : a two - component tax considering a basic ad - valorem tax and profitability tax with higher sliding - scale rates for copper producers ; and (iv) Corrective taxes : to foster ESG programs and regional development . The government expected to collect US $ 12 , 000 million ( 4 . 1 % of GDP) with this reform to fund social expenditure . After the rejection of the proposal, the discussion of the reform focused on the mining royalty, where a new tax project for mining was proposed, which was 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 . 35 billion), of which US $ 450 million will be distributed directly to promote the productive development of regions and districts throughout the country . 10

11 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, 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 . 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 (Nov - 24) In 6 months (Nov - 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 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 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 .

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

Santander Life continues to be the main contributor in new client growth due to the success of the Meritolife program of this product and the digital onboarding process of current account openings . Life clients are quickly monetized and have a high NPS score throughout the incorporation process . SMEs 13% High income 68% 15 19% Middle income Mass income 0.5%

16 Also, with the objective on continuing to our commitment on financial inclusion, we launched “Más Lucas” the first 100 % digital on - boarding interest - bearing sight and savings account for the mass market . This product does not charge any maintenance or transaction fees, on the other hand, the sight account pays a fixed rate on a monthly basis in respect to the balance maintained in the account . Retail Banking loans grew 2 . 4 % YTD and 1 . 3 % compared to the previous quarter . Mortgage loans continued to increase 2 . 4 % QoQ, driven by the increase in the value of the UF (which increased 1 . 4 % QoQ), while the origination of new mortgages is very low as a result of high rates and high inflation . Credit cards and other consumer loans increased 2 . 1 % and 1 . 5 % respectively in the quarter . The foregoing is offset by a drop in loans to SMEs and car loans . On the other hand, total deposits in this segment increased 1 . 3 % compared to December 31 , 2022 , and 1 . 1 % QoQ due to the greater growth in time deposits despite demand deposits continuing to decrease after the excess liquidity following the strong inflow during the pandemic due to state aid and withdrawals from pension funds, as well as the switch to higher yielding time deposits . Results: The net contribution of retail banking increased 21 . 0 % YoY . The margin increased 18 . 5 % YoY due to a better mix of funding and loan growth . Fees in this segment increased strongly by 29 . 3 % 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 57 . 4 % 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 . 5 % YoY as the Bank continues its digital transformation, generating greater operating efficiencies . Compared to 1 Q 23 , the net contribution of retail banking increased 6 . 5 % QoQ . The margin increased by 3 . 2 % QoQ mainly due to the higher spreads earned on demand deposits . Commissions in this segment increased 1 . 1 % in the quarter, as a consequence of greater card fees, the consolidation of Getnet and greater fees generated by insurance brokerage . Provisions decreased 6 . 4 % QoQ mainly due to the decrease in the SME portfolio and the recovery of individual and SME loans during the quarter . The operating costs increased 5 . 8 % QoQ, mainly due to greater personnel expenses due to seasonal factors in 1 Q 23 .

During the quarter the portfolio increased 0 . 2 % QoQ, driven mainly by positive translation gains from loans denominated in UF . Deposits decreased 3 . 6 % YTD and 4 . 5 % QoQ due to the high liquidity levels that these customers had in 2021 which has now almost totally drained in 2023 . The main strategic objective of this segment is to focus on the client's total profitability, in lending and non - lending activities . Green financing has also been a focus, with Ch $ 114 billion in green loans disbursed in the first semester of 2023 . Results: Net contribution from the Middle Market increased 38 . 0 % YoY, with an increase in total revenues of 21 . 6 % due to a 22 . 8 % growth in net interest income as a result of a better loan and deposit spread and volume growth . Additionally, commissions increased by 7 . 1 % in line with the greater activity of clients in payments and foreign trade, as well as leasing, factoring and structuring of operations . Provisions in this segment decreased 35 . 4 % YoY due to higher risk in sectors such as construction during 2022 that were eliminated from the portfolio . Expenses remained stable with a slight decrease of 0 . 1 % mainly due to efficiencies generated by technological projects, as well at the appreciation of the Chilean peso in 6 M 23 . In the quarter, the net contribution of Middle Market decreased 9 . 5 % QoQ, due to a greater provision expense of 94 . 1 % QoQ because of a release of provisions for real estate projects in 1 Q 23 that have been recovered as the bank has finished their construction (around 10 projects), which was not repeated in 2 Q 23 . Operating expenses also increased 5 . 8 % QoQ due to seasonality in 1 Q 23 which led to lower personnel expenses compared to 2 Q 23 .

Deposits increased 12 . 5 % YTD due to higher demand for time deposits in CLP considering higher rates . Compared to 1 Q 23 , deposits fell slightly by 0 . 6 % mainly to a decrease in demand deposits fell . Results: Total income from this segment increased 84 . 5 % YoY Net income from interest and readjustments increased 76 . 9 % YoY due to the increase in loans compared to June 2022 , particularly foreign trade, and 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 54 . 1 % due to a better performance from financial advisory and financial brokerage and also greater customer treasury income of 30 . 5 % 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 3 . 9 % YoY mainly due to depreciation of the Chilean peso compared to 4 Q 22 , reducing expenses in technology . Compared to 1 Q 22 , expenses increased 6 . 2 % due to higher amortization of technology and administrative costs . In the quarter, SCIB's net contribution fell 11 . 3 % QoQ due to lower revenues from financial transactions as 1 Q 23 was very strong .

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 held to collect investment portfolio . The held to collect portfolio mainly includes Central Bank bonds held as collateral by the Central Bank 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 1 Q 23 , the net loss of the corporate center increased 4 . 6 % QoQ as the high rates and lower inflation continued to pressure our margins in the quarter .

20 Section 4: Balance sheet and results Balance sheet Loan growth led by consumer loans Total loans increased 0 . 6 % QoQ and 1 . 3 % YTD, mainly driven by the retail segment, by mortgage loans and consumer loans (credit cards) . Approximately 59 % of our loan portfolio is indexed to inflation through the UF, the majority of which are mortgage loans and around 40 % of commercial loans . Regarding in loans in foreign currency, around 20 % of our commercial loan portfolio is denominated in foreign currency, mainly US dollars, especially in the Middle Market and CIB segment .

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. Loans from the CIB segment decreased 2 . 5 % YTD and 1 . 4 % QoQ influenced by lower conversion gains caused by the appreciation of the peso in 2023 compared to the end of 2022 ( 5 . 7 % ) and, on the other hand, because in 2022 several successful large short - term loan operations were carried out . The Middle market segment's loan portfolio slightly increased 0 . 2 % QoQ, mainly driven by positive translation gains on UF - denominated loans, and fell 0 . 8 % since December 31 , 2022 affected by the translation loss of dollar - denominated loans as described above because the peso appreciated in 2023 . Retail banking loans grew 1 . 3 % QoQ and 2 . 4 % from December 31 , 2022 . Consumer loans increased 1 . 3 % QoQ and 2 . 4 % from December 31 , 2022 . This it was driven by a 2 . 1 % QoQ increase in credit cards .

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, increasing is total balance compared to pre pandemic levels . Origination of new mortgage loans has fallen as inflation and rates remain high, therefore the mortgage portfolio growth of 2 . 4 % QoQ and 4 . 3 % from December 31 , 2022 is due to the indexation of this loan book to the UF, growing slightly above the value of the UF . As for SMEs, the demand for new loans remains moderate after a strong increase in 2020 and 2021 for the Fogape and Fogape Reactiva loan programs . Given the above, the SME segment loan book decreased 0 . 6 % QoQ and 3 . 6 % from December 31 , 2022 as SMEs repaid FOGAPE loans . A new FOGAES program was launched by the government in April, in which the bank is participating . The programs objective is to support families in obtaining a mortgage loan for the purchase of their first home, and to support access to financing companies in the real estate and construction sectors . Also for 2023 , the government announced a new Fogape scheme to provide state guarantees to reactivate lending to micro and small and medium companies . 21

This explains the 3 . 9 % QoQ rise in our financial investment portfolio . It is important to point out that our financial investment portfolio is only comprised of HQLA such as Central Bank bonds and notes, Chile sovereign bonds and U . S . treasuries . Moreover, the utilization of the Central Bank Credit lines also requires us to set aside collateral . The instruments used as collateral for the Central Bank lines have been highly rated loans and Central Bank bonds . As a result of these factors, in 2021 , in Chilean GAAP and in line with IAS 39 , the Bank reclassified Ch $ 4 . 7 billion of assets available for sale (AFS) to the investment portfolio Held to Maturity (HTM) . The instruments included as HTM are being used as collateral for the Central Bank Credit Lines with similar maturity . Currently the Bank has around 80 % of the collaterals required in Central Bank bonds, higher than the industry average which is 50 % . In the unlikely case that the Bank should need more liquidity, the Central Bank has the Permanent Liquidity Facility where we can sell these instruments at market value . The market value of this portfolio is Ch $ 4 , 512 , 977 .

This rate increase and maintained at this high level has a direct impact on our funding mix . The Bank's total deposits increased 0 . 3 % QoQ and 4 . 1 % since December 31 , 2022 . The increase was driven by time deposits that increased 4 . 4 % QoQ and 14 . 7 % YTD mainly in the CIB segment, due to the fact that the increase in rates led our clients to switch to more attractive deposits explaining the decrease of 3 . 9 % QoQ and 5 . 8 % YTD of demand deposits . Bonds increased 2 . 6 % QoQ and 5 . 0 % YTD .

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 June 2023 decreased by 44 . 5 % compared to the same period in 2022 . This decrease in NII was mainly due to the lower inflation in the period, higher funding costs due to the higher MPR and a lower carry earned over our financial investments classified as held to collect that are at a fixed rate . This was partially offset by a higher rate earned over average generating assets due to higher inflation and higher spread earned over deposits .

27 The Bank has a shorter duration of interest - bearing liabilities than interest - bearing assets, and therefore, when rates rise sharply, our liabilities re - price faster than our assets, pushing margins down . During the second quarter of 2023 , the Central Bank of Chile maintained the MPR at 11 . 25 % , compared to 9 . 0 % in the same period last year . Given this, net interest income, which excludes the portion of assets and liabilities linked to inflation, decreased 15 . 1 % in 6 M 23 compared to 6 M 22 . Net income from readjustments decreased 61 . 8 % in 6 M 23 compared to the same period in 2022 , given that the UF variation reached 2 . 8 % in 6 M 23 compared to 6 . 8 % in the same period in 2022 . On the other hand , the Bank has been decreasing the difference between the interest - generating assets indexed to the UF and the liabilities indexed to the UF (called GAP UF), totaling an average of Ch $ 6 , 103 , 348 million as of June 2023 , as a result of inflation expectations that have been falling rapidly . Due to all of the above, the NIM reached 2 . 1 % as of June 30 , 2023 , lower than the 4 . 1 % in the same period of 2022 . In 2 Q 23 , total income net of interest and readjustments decreased by 8 . 2 % compared to 1 Q 23 and the NIM in 2 Q 23 decreased to 2 . 0 % . Firstly, we have that the variation of inflation measured by the variation of the UF was 1 . 4 % in 2 Q 23 , slightly higher than the 1 . 3 % of 1 Q 23 , which added to a higher GAP UF in the quarter, explains the 27 . 6 % increase in net income from readjustments in 2 Q 23 compared to 1 Q 23 . Secondly, the monetary policy rate remained at 11 . 25 % in both quarters, but our retail financing sources such as time deposits continue to grow as our clients sought higher profitability given the current high interest rates, switching from demand deposits to this type of product . This continues to put pressure on the cost of funding that increased from 6 . 8 % in 1 Q 23 to 7 . 3 % in 2 Q 23 . Given the above, net interest income decreased by 29 . 0 % . With the inflation data of - 0 . 2 % in the month of June, we expect the Central Bank to begin lowering the MPR at its next Monetary Policy Meeting of the Chilean Central Bank on July 31 and to continue making rapid cuts during the year, reaching December 31 , 2023 with a MPR of around 7 . 25 % . For this reason, our NIM expectation for 2023 is a recovery in the second semester as short - term interest rates drop, closing 2023 with a NIM of around 2 . 3 % 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 pension fund withdrawals, resulting in a positive evolution of asset quality during that period . Currently, with an economy that continues to slow down and without the excess liquidity in households that we had during the pandemic, asset quality is returning to pre - pandemic levels . Given the above in 2 Q, the non - performing loan ratio (NPL) increases from 1 . 5 % in 2 Q 22 to 2 . 1 % in 2 Q 23 . Along the same lines, the impaired portfolio ratio increased from 4 . 7 % in 2 Q 22 to 5 . 4 % in 2 Q 23 . Lastly, the expected loss ratio (provisions for credit risk divided by total loans) remains more stable, increasing to 2 . 8 % in 2 Q 23 , from a previous 2 . 7 % as a result of higher provisions constituted in the last periods . The expense for net credit losses totaled Ch $ 231 , 587 million in the six - month period ended June 30 , 2023 , an increase of 42 . 4 % compared to the same period in 2022 and in the same line, the cost of credit goes from 0 . 87 % at the end of June 2022 to 1 . 19 % at the end of June 2023 .

The consumer NPL increased from 1 . 3 % in June 2022 to 1 . 8 % in June 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, mainly affecting clients that were already impaired before the pandemic . Given the above, the total consumer impaired ratio increased, from 3 . 2 % in June 2022 to 4 . 2 % in June 2023 . In September 2022 , the Board of Directors approved transferring the amount of Ch $ 120 , 000 million from voluntary provisions of the commercial portfolio to voluntary provisions of the consumer portfolio, in four equal installments of Ch $ 30 , 000 million, starting with the first one in September 2022 . This was done in order to cover for the expected rise in consumer loan loss provisions as result of the new standardized provisioning model being formulated by the FMC . For this reason, the coverage of consumer loans increased from 435 . 2 % in June 2022 to 478 . 0 % in June 2023 . Compared to 1 Q 23 , the expense of net provisions for consumer loans increased 10 . 5 % in 2 Q 23 due to a greater deterioration observed as a result of a challenging economic environment for households, with lower quality of employment and less available liquidity . Commercial loan provision expenses decreased 13 . 2 % YoY in the six months ended June 30 , 2023 and decreased 2 . 9 % QoQ . NPLs increase from 1 . 9 % in June 2022 to 2 . 6 % in March 2023 to 2 . 9 % in June 2023 as well as the impaired ratio that increased from 6 . 5 % to 7 . 3 % to 7 . 6 % respectively . This is mainly due to a more challenging macroeconomic environment for companies, high rates and activity that is slowing down . On the other hand, as a result of the transfer of $ 120 , 000 million of voluntary provisions to the consumer portfolio, the coverage ratio of this portfolio drops sharply from 244 . 9 % in June 2022 to 149 . 5 % in June 2023 . Provision expenses for mortgage loans decreased 17 . 6 % in 6 M 23 compared to the same period of 2022 and decreased 17 . 1 % QoQ . Given the decrease in liquidity and high inflation, the mortgage NPL increased from 0 . 9 % in June 2022 to 1 . 0 % in March 2023 to 1 . 4 % in June 2023 . On the other hand, the mortgage impaired ratio increased from 2 . 9 % in June 2022 to 3 . 1 % in March 2023 to 3 . 4 % in June 2023 . With the above, the mortgage coverage ratio reached 66 . 1 % as of June 2023 .

Personnel expenses increased 1 . 1 % in 6 M 23 compared to the same period in 2022 , due to the fact that salaries are adjusted according to inflation, which is partly offset by a lower number of collaborators, which falls 4 . 0 % in the same period . Compared to 1 Q 23 , they grew 17 . 6 % QoQ due to seasonality caused by the holiday season in Chile . Productivity also continues to improve, with volumes (loans plus deposits) per branch increasing 22 . 3 % YoY and volumes per employee growing 6 . 8 % YoY . This increase in productivity is a reflection of the strength of our digital channels and a higher level of automation in the different cost centers . Administrative expenses increased 3 . 7 % in 6 M 23 compared to the same period of 2022 . Compared to June 2022 , the value of UF has increased 9 . 1 % , increasing expenses related to leases and other long - term contracts and services . In 2 Q 23 , administrative expenses decreased 6 . 7 % compared to 1 Q 23 . This was due to lower marketing expenses as well as lower branch maintenance expenses (cleaning, community association expenses, etc . ) as a result of their closing in the quarter . Amortization expenses increased 10 . 8 % in 6 M 23 compared to the same period in 2022 . This increase is explained by higher software amortization due to digital banking developments as part of our plan to improve productivity . Other operating expenses decreased 87 . 0 % in 6 M 23 compared to the same period of 2022 and 89 . 7 % QoQ . The decrease responds to lower compensation expenses as well as a lower disbursement in cybersecurity insurance as the Bank has been implementing different measures such as general improvements in the security of digital channels, longer and more complex web access codes , physical cards without visible numbers and dynamic CVV, etc . Other operating income, income from investments in companies and taxes In these items we highlight the higher result from investments in companies due to the better results of Transbank in the quarter. As a reminder, we have a 25% interest in Transbank, and the Bank is in the process of selling its interest in this company. 35

Approx. 15% ROE ROE, growth of equity and risk - weighted assets and dividend policy. Finishing the year > 10.5% CET1 Long term ROE expectations remain at 17% - 19%. Section 6: Risks Risk management in 2 Q 23 has focused on preparing our risk structure for an expected slowdown in economic activity in 2023 . 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 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 . 38

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 : All debtors' loans are to be maintained in the impaired portfolio until their payment ability or performance is normalised, irrespective of penalty procedures for each loan, particularly those that meet the conditions of Title II of Chapter B - 2 of the CNC . 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 . 39

40 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 . During 2022 , the FMC published a draft for a new standardized provisioning model for consumer loans for banks . While the final version is yet to be published, our initial estimate was a one - time expense of between Ch $ 100 , 000 million to Ch $ 150 , 000 million that can be covered with the voluntary provisions that already have been established in previous periods .

42 Credit quality of debtors At the end of June 2023 , the non - performing loan rate continued to increase after historically low levels, reaching 1 . 5 % in June 2022 to 1 . 8 % in December 2022 to 2 . 1 % in June 2023 , in line with pre - pandemic levels . At the same time, the impairment ratio ended at 5 . 4 % in June 2023 , increasing from 4 . 8 % in December 2022 and 4 . 7 % in June 2022 . As household liquidity normalizes after withdrawals from pension funds and emergency family income in 2021 and the economy begins to slow, asset quality is expected to return to pre - pandemic levels . The coverage ratio, including additional provisions, reached 165 . 0 % in June 2023 and the expected loss ratio (credit risk provisions divided by total loans) remained stable at 2 . 8 % .

Distribution by economic sector The Bank's portfolio is also highly diverse in terms of economic sector, with no particular industry representing a significant portion, therefore increasing the possibility of maintaining a stable loan book through time. 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 . 43

44 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 June 30 , 2023 the Bank's HQLA amounted to Ch $ 6 , 573 , 100 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 June 30 , 2023 , this indicator for Banco Santander Chile was 175 . 8 % , 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 June 30 , 2023 , the NSFR was at 109 . 4 % . Evolution of the NSFR Tier 1: Available, 858,405 Tier 1: Fixed income, 5,707,516 Tier 2: Fixed income, 7,179 153.3% 45 198.6% 175.2% 182.3% 175.8% Jun/22 Sep/22 Dec/22 Mar/23 Jun/23

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 . 108.5% 46 115.6% 116.0% 113.2% 109.4% Jun/22 Sep/22 Dec/22 Mar/23 Jun/23

Due to the rules established by the Assets and Liabilities Committee (ALCO) and the Markets Committee, 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 .

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 . Operational risk In general, the indicator of operational risk events on operating income has remained stable and below the system average . As of June 30 , 2023 , operating loss increased 31 . 4 % compared to the same period last year explained by the increase in clients and products and greater losses due to processing and fraud .
