Strategy

Banco Santander Brasil is the only international bank with scale in the country. We are convinced that the best way to grow in a profitable, recurring and sustainable manner is by providing excellent services to enhance customer satisfaction levels and attract more customers, making them more loyal.

Executive Summary

Our performance is a testament to the sustainability of our business model, with afocus on the customer and on generating greater value to shareholders. Although economic activity indicators still point to weak domestic demand, we continue to expand our loan portfolio through profitable market share gains. This annual expansion of the loan balance for the seventh consecutive quarter derived from solid risk management and the effectiveness of our models, maintaining quality indicators at controlled levels. As a result, our total revenue has grown steadily on a year-on-year basis since 1Q15, with positive contributions from both net interest income and fees. At the same time, our industrial operating model enables the constant improvement of the efficiency ratio. Due to the combination of all these factors, our profitability has remained with yearly growth and consistent.

Managerial net profit totaled R$ 8,992 million in the first nine months of 2018, growing 24.9% in twelve months and 2.8% in three months.	Profitability The return on average equity (ROAE), adjusted for goodwill, was 19.4%, in the first nine months of 2018, representing a twelve-month increase of 3.1 p.p. This performance stems from the rise in revenues, through the expansion of our customer base, and greater operational efficiency.
Total revenues amounted to R$ 43,797 in the first nine months of 2018, rising 11.7% in twelve months (or R$ 4,596 million) and 0.2% in three months. Net interest income reached R$ 31,253 million in the first nine months of 2018, meaning a 12.3% increase in twelve months, influenced by growth in the average loan balance and a stronger participation of retail segments. In three months, net interest income rose 1.6% due to higher revenues from market activities and deposits, while the loan margin was affected by the tightening of spreads. Fees came to R$ 12,544 million, advancing 10.3% in twelve months, driven by an increased customer base and loyalty. Among the revenues that comprise this result, the highlights continue to be credit cards and acquiring activities, alongside current account services and insurance fees. In three months, fees fell by 3.3%, largely explained by fees revisions according to market guidelines and reduced activity in capital markets.	Allowance for loan losses reached R$ 7,874 million in the year through September 2018, a 11.6% increase, below of the growth of the loan portfolio. In three months, allowance for loan losses rose 0.6%. This evolution in both periods reflects the strength of our risk management and the effectiveness of our mathematical models.
	General expenses totaled R$ 14,692 million in the first nine months of 2018, climbing 5.1% in twelve months and 3.2% in three months. This rise in both periods is primarily attributed to higher data processing expenses and personnel expenses. It is worth mention that the expansion of our customer base alongside increased transactionality affect our data processing expenses. The efficiency ratio reached 39.7% in the third quarter of 2018, went up 0.1 p.p. in three months. In the first nine months of 2018, the ratio was 39.8% meaning an improvement of 4.2 p.p. in twelve months.

BALANCE SHEET AND INDICATORS

The total loan portfolio amounted to R$ 298,433 million at the end of September 2018, expanding by 13.5% in twelve months (or a 10.4% increase, disregarding the exchange rate fluctuation effect). This quarter, the Individuals and Consumer Finance segments were once again the growth highlights, advancing 22.6% and 20.7% in twelve months, respectively. It is important to note our profitable market share gain in Brazil's total credit market, which reached 9.4% in September of 2018 (+0.8 p.p. in twelve months). In three months, the total portfolio grew 2.7%. The expanded loan portfolio reached R$ 380,713 million, meaning growth of 13.1% in twelve months and 3.4% in three months.	Total equity excluding R$ 727 million related to the goodwill balance, was R$ 64,824 million at the end of September 2018, climbing 5.3% in twelve months and 3.7% in three months.
Funding from clients totaled R$ 336,997 million at the end of September 2018, rising 9.0% in twelve months and 3.7% in three months. In both periods, the performance was chiefly influenced by the increase in time deposits, which went up 25.7% in twelve months and 3.9% in three months. Savings deposits also made a positive contribution, with growth of 15.2% in twelve months and 4.4% compared to June 2018.	Quality indicators The over-90-day delinquency ratio stood at 2.9% in September 2018, stable in twelve months. In three months, this ratio was 0.1 p.p. higher due to a one-off case in the Corporate segment. The cost of credit hit 3.1% in the third quarter of 2018, which represents a decrease of 0.2 p.p. in twelve months and a 0.1 p.p. decline in three months. The coverage ratio came to 207% in September 2018, falling 22.6 p.p. in twelve months and 12.3 p.p. in three months. The performance in both periods was impacted by the one-off case mentioned above. Portfolio quality indicators remain under control, owing to the effectiveness of our models and the strength of our risk management.
	Capital indicators The BIS ratio stood at 15.3% in September 2018, meaning a reduction of 0.9 p.p. in twelve months and an increase of 0.5 p.p. in three months. The fully-loaded CET1 ratio reached 12.6%, down 0.7 p.p. in twelve months and up 0.2 p.p. in three months.

Net Interest Income Net interest income totaled R$ 31,253 million in the first nine months of 2018, growing 12.3% in twelve months (or R$ 3,424 million) and 1.6% in three months. Revenues from loan operations advanced 19.2% in the year to date compared with the same period last year, given the increase in the average volume of the loan portfolio and greater participation of retail segments. In three months, these revenues were slightly higher, by 0.1%, as consequence of stronger volumes, which were partially offset by tighter spreads, in part attributed to regulatory changes in credit cards. Funding revenues in the first nine months of 2018 fell by 10.0% in twelve months, influenced by the decline in the benchmark interest rate in the period. In three months, these revenues experienced a 6.3% increase due to higher volumes. Other interest income, which comprises the result of the structural gap in the balance sheet interest rate and activities with treasury clients, among others, expanded by 4.6% in twelve months and 4.5% in three months, thanks to higher revenues from market activities.

Fees Revenues from Banking Services Revenues from banking services and fees totaled R$ 12,544 million in the year to date, representing a 10.3% rise in twelve months, mostly driven by credit cards and acquiring activities, current account services and insurance fees. In the quarter, these revenues declined by 3.3%. Cards and acquiring fees amounted to R$ 4,227 million in the first nine months of 2018, rising 18.1% relative to the same period of 2017, recording the tenth consecutive quarter of double-digit annual growth. This result is mainly attributed to higher card and acquiring turnover. In the quarter, these revenues went up 3.8%. Current account service fees came to R$ 2,475 million in the year to date, advancing 15.4% in twelve months and 3.0% in three months, in line with the growing base of active current account holders, which has been expanding for 40 consecutive months.

Insurance fees stood at R$ 1,989 million in the first nine months of 2018, representing growth of 10.8% in twelve months, supported by the credit dynamics in the period. In three months, these revenues declined by 3.6%, given the greater concentration of campaigns that normally occur in the second quarter and affect the comparison. Collection service fees reached R$ 1,120 million in the year to date, climbing 9.4% in twelve months and dropping 3.1% in three months. Lending fees were R$ 1,081 million in the first nine months of 2018, down 3.4% in twelve months and 25.7% in three months. This performance is mostly explained by fee revisions according to market guidelines. Securities placement, custody and brokerage fees totaled R$ 464 million in the year to date, decreasing by 7.1% in twelve months. In three months, these revenues saw a 42.1% drop due to lower capital market activities on the back of the political-economic scenario in the period.

General Expenses (Administrative + Personnel) General expenses, including depreciation and amortization, amounted to R$ 14,692 million in the first nine months of 2018, meaning increases of 5.1% in twelve months (or R$ 708 million) and 3.2% in three months. The performance in both periods is primarily attributed to higher data processing and personnel expenses, accompanying the business dynamics. Administrative and personnel expenses, excluding depreciation and amortization, came to R$ 13,020 million in the year to date, rising 4.4% in twelve months and 3.3% relative to the previous quarter. Personnel expenses, including profit-sharing, reached R$ 6,926 million between January and September 2018, climbing 3.0% in twelve months (or R$ 201 million), largely owing to higher labor charges and compensation expenses, in line with our meritocratic culture and the performance of our business. In three months, these expenses rose 2.0%. Both periods were also impacted by the collective bargaining agreement that took place in September 2018. Administrative expenses, excluding depreciation and amortization, stood at R$ 6,094 million in the first nine months of 2018, advancing 6.1%, in twelve months (or R$ 353 million) and 4.8% in comparison with the prior quarter. These increases were largely due to higher data processing expenses, given greater transactionality and growth in our customer base. Some of these changes were offset by lower expenses with outsourced and specialized services. Depreciation and amortization expenses were R$ 1,672 million in the year to date, up 10.1% in twelve months and 2.3% in three months.

Coverage Ratio The balance of allowance for loan losses came to R$ 18,224 million at the end of September 2018, increasing 5.2% in twelve months and 0.7% in three months. This evolution is in line with the expansion dynamics of our loan portfolio and shows that the provisioning levels are adequate. The coverage ratio stood at 207% at the end of September 2018, or a decline of 22.6 p.p. in twelve months and 12.3 p.p. lower in three months. These figures were impacted by a one-off case in the Corporate segment that occurred in this quarter.

Delinquency Ratio over-90-Day The over-90-day delinquency ratio stood at 2.9% at the end of September 2018, stable in twelve months and a 0.1 p.p. rise in three months. The ratio remains at a controlled level, attesting to the effectiveness of our models and our preventive risk management. Delinquency in the Individuals segment was 3.8% in the period, advancing 0.1 p.p. in twelve months and remaining stable compared with the previous quarter. Delinquency in the Corporate and SME segment came to 1.9% at the end of September 2018, stable in twelve months. In the quarter, this ratio increased by 0.2 p.p., owing to the one-off case discussed earlier in this report.

Delinquency Ratio 15-to-90-day The 15-to-90-day delinquency ratio reached 4.0% at the end of September 2018, dropping 0.5 p.p. in twelve months and 0.2 p.p. in three months. In the Individuals segment, the ratio stood at 5.6%, which represents a decline of 0.2 p.p. in twelve months and a 0.1 p.p. decline in three months. In the Corporate & SME segment, this ratio came to 2.1% at the end of September 2018, falling 1.0 p.p. in twelve months and 0.3 p.p. compared to the prior quarter.

¹ According to ANBIMA criteria.

The loan portfolio to customer funding ratio was 88.6% at the end of September 2018, meaning a 3.6 p.p. increase in 12 months and a 0.8 p.p. reduction in three months. The liquidity metric adjusted for the impact of reserve requirements and medium/long-term funding reached 86.1% in September 2018, down 2.3 p.p. in twelve months and 1.6 p.p. in three months. The Bank is in a comfortable liquidity situation, with stable funding sources and an adequate funding structure.

The BIS ratio stood at 15.3% at the end of September 2018, a reduction of 0.9 p.p. in twelve months. This change is chiefly explained by the impact on capital deductions under the Basel III schedule, which went from 80% in 2017 to 100% in 2018. In the quarter, the ratio rose 0.5 p.p., driven by an improved CET1 ratio, given the increase in retained earnings and better deduction levels, which offset the RWA growth in the period. It is important to mention that the use of the internal model for Market Risk was approved in the second quarter of 2018 by the Brazilian Central Bank. Thus, the calculation of this portion is now obtained from the maximum value between the internal methodology and 90% of the standardized approach. Since January 2018, the capital requirement has been changed from 9.25% to 8.625% + conservation capital of 1.875% + additional CET1 for systemically important financial institutions in the Brazilian market of 0.5%, totaling 11%. Tier I Capital is 8.375% and CET1 is 6.875%.

In March 2013, the Brazilian Central Bank issued the Basel III rules on capital definition and risk management. These criteria will be gradually implemented by 2019. If we were to apply Basel III rules immediately and in full, our CET1 would have reached 12.6% in September 2018, down 0.7 p.p. in twelve months, affected by the RWA increase. In the quarter, the ratio rose 0.2 p.p., owing to the capital improvement arising from higher retained earnings and better deduction levels.

¹ Foreign Exchange Hedge: under Brazilian tax rules, gains (losses) derived from exchange rate fluctuations on foreign currency investments are not taxable (tax deductible). This tax treatment leads to exchange rate exposure to taxes. An exchange rate hedge position was set up with the purpose of protecting the net profit from the impact of foreign exchange fluctuations related to this tax exposure.
² Credit Recovery: reclassified from revenue from loan operations to allowance for loan losses and, from 2017 onwards, it includes provision for guarantees provided.
³ Amortization of Goodwill: reversal of goodwill amortization expenses. 
⁴ Exchange Rate Fluctuation: includes, in addition to the effect of the exchange rate fluctuation, reclassifications between different lines of the Bank s results (other operating income/expenses, allowance for loan losses and non-operating result) for better comparability with previous quarters.
⁵ Other events: 
 
2017
3Q17: Adhesion effect to the installment payment program for outstanding taxes and social security debts (in accordance with Provisional Measure No. 783/2017).

2018
1Q18: Adhesion effect to the installment payment program for outstanding taxes and social security debts (in accordance with Provisional Measure No. 783/2017).
2Q18: Includes a gain of R$ 816 MM from the adjustment of post-employment benefits, additional provisions for contingencies in the amount of R$ 358 MM, impairment of intangible assets (systems acquisition and development) in the amount of R$ 306 MM and a write-off of tax credits in the amount of R$ 74 MM.
3Q18: Net Interest Income, Allowance for Loan Losses and Other Operating Income and Expenses: reclassifications between the lines referring to adjustments in the valuation of assets related to the impairment of securities (R$ 173 MM) and derivative instruments (R$ 127 MM)
