Non-interest expenses totaled BRL 16.7 billion, up 3.3% in the quarter. This increase is expected due to the seasonality of the first quarter, when expenses are usually lower, particularly as a result of the dynamics of personnel expense accounting, and due to lower activity and transaction volumes at the beginning of the year, which impact transactional expenses. The efficiency ratio in Brazil reached 35.5% in the second quarter of 2026, reflecting productivity gains from the technology investments made over the past few years. Itaú ended the quarter with comfortable levels of capitalization and liquidity. The Common Equity Tier 1 (CET1) ratio reached 12.3%, supported by organic capital generation and a prudent resource management policy. Itaú revised its projections for Commissions and fees and results from insurance operations for 2026. The bank now projects growth between 2.0% and 5.0%. The adjustment in the growth expectation is mainly related to higher volatility in the capital markets than projected at the beginning of the year. Expectations for all other lines disclosed in the 2026 Guidance remained unchanged. Throughout the quarter, Itaú continued to advance its agenda of transformation, operational efficiency and client experience enhancement. On this front, the highlight was the launch of ia.i, the new conversational experience integrated into the Itaú SuperApp that combines artificial intelligence, financial advisor and human interaction to support clients in their day-to-day decisions. The initiative represents another step in the bank's AI First strategy and reinforces its long-term vision of using technology to enhance the quality, efficiency, scale and personalization of financial services.

In BRL million Itaú Unibanco Market Consensus³ % Managerial Result 12,407 12,466 -0.5% "The results of the quarter demonstrate that the sustainable growth of the credit portfolio is a direct outcome of the bank's quality and diligence in granting credit responsibly and sustainably, based on a careful analysis of clients' needs. Credit lines designed for different client profiles, such as private-sector payroll loans, are advancing consistently and with controlled delinquency levels because they are offered within clients' actual repayment capacity. We remain active in several debt restructuring initiatives, which play a fundamental role in financial reabsorption and reintegration. However, they are only one stage of a much broader strategy. A genuinely healthy loan portfolio is not built through renegotiation, but through the quality of credit granting, the correct pricing of risk, the capacity for credit recovery and the dynamic monitoring of our clients' real needs throughout the entire cycle. It is this analytical discipline, combined with the intensive use of technology and artificial intelligence models, that ensures the stability of our results in any economic scenario.” Gabriel Amado de Moura CFO of Itaú Unibanco
