We started 2024 optimistic and committed to deliver even more value to our clients, stockholders and employees, taking advantage of the changes we have implemented in the organization so that our clients are placed in the center of all our decisions.” Milton Maluhy Filho Itaú Unibanco’s CEO Itaú Unibanco’s profit increases 15.7% in 2023 and loan portfolio reaches R$1.2 trillion Annual profit was R$35.6 billion, mainly driven by the increase in loan portfolio and margin with clients. São Paulo, February 5, 2024 - In 2023, Itaú Unibanco’s recurring managerial result totaled R$35.6 billion, up 15.7% year-on-year with an annualized recurring managerial return on average equity of 21.0%. Among the factors that most influenced the results are the growth of the loan portfolio, the higher liabilities’ margin, in addition to the positive impact of repricing of our working capital. Accordingly, financial margin with clients increased. The result was also influenced by the increase in commissions and fees and result from insurance operations, driven by higher card revenue, in both issuance and acquiring services, and by a better performance of insurance operations. The total loan portfolio grew 3.1% in relation to 2022, reaching R$1,176.5 billion in December 2023. In the individuals portfolio, the growth was due to the increases of 13.7% in personal loans, 6.8% in mortgage loans, a market in which the bank has made headway in our clients’ journey over this period, and 5.1% in vehicles. The companies loan portfolio2 was up 0.5% in the 12-month period with significant changes recorded in rural loans, mortgage loans, and BNDES and onlending. Non-performing loans over 90 days overdue (NPL 90) reached 2.8% in December 2023, the lowest amount in the last five quarters. This decrease was due to the reduction in this ratio for individuals in Brazil and reflects the bank's strategic risk management. Cost of credit totaled R$36.9 billion in 2023, up 14.4% on a year-on-year basis, mainly due to the higher provision for loan losses driven by the increase in the loan portfolio in the Retail Business segment in Brazil and the normalization of the provision flow in the Wholesale Business segment also in Brazil; rise in impairment of corporate securities; and increase in discounts granted. 1 Includes financial guarantees provided and private securities. 2 Without financial guarantees provided and private securities.
