Funding NII also improved, driven by higher volumes and a better mix, more than compensating for fewer business days in the quarter. Over twelve months, client NII rose 6.6%, driven both by funding NII, benefitting from higher Selic rates and volumes, and by the positive contribution from credit NII, due to volume, and working capital, the latter supported by the Selic. It is worth noting that the deferral expense arising from the reclassification under CMN Resolution No. 4,966/21 negatively impacted spreads by 0.2 p.p. on an annual basis. Market NII losses widened in the quarter, totaling loss of R$1,486 million versus a negative R$1,348 million in the previous quarter, mainly due to lower treasury results. For the year, the impact was driven primarily by negative interest-rate sensitivity. Evolution of net interest income Spread (p.a.)

On an annual comparison, NII declined 4.0%, reflecting the performance of market NII, negatively affected by its sensitivity to higher interest rates, while client NII increased 6.6%, supported by wider spread and higher volumes during the period. 198 97 (730) (1,348) (1,486) 15,780 15,825 16,127 16,556 16,818 15,978 15,922 15,396 15,208 15,332 10.49% 10.51% 10.75% 10.85% 10.67% -2.00% 0.00% 2.00% 4.00% 6.00% 8.00% 10.00% 12.00% (2,000) 3,000 8,000 13,000 18,000 23,000 28,000 4Q24 1Q25 2Q25 3Q25 4Q25 0.18 p.p. -0.17 p.p.

The year-on-year comparison is also affected by changes in the provisioning model introduced by CMN Resolution No. 4,966/21, adopted as of 2025.

Result from loan losses and cost of risk R$ million Managerial result from loan losses totaled R$6,105 million in 4Q25, declining 6.4% versus the prior quarter, mainly reflecting the acceleration of coverage carried out throughout the year and the absence of relevant one-off effects, such as specific wholesale cases.

The loan portfolio totaled R$566,074 million in December 2025, up 2.9% quarterly, with growth across all major segments. Performance was led by a 5.4% increase in Consumer Finance and in SMEs, particularly in working capital. Similarly, the Individual loan portfolio rose 1.6% in the quarter, supported by credit cards (+9.3%) and mortgages (+2.7%), partially offset by declines in payroll loans (-3.2%) and rural credit (-2.3%), reflecting continued selectivity in origination and a focus on higher returns on capital. The Corporate portfolio grew 1.9% in the quarter, driven by foreign trade lines and FX effects. Excluding FX, growth would have been 0.5% over three months and 3.3% over the year. The total loan portfolio would have advanced 2.5% in the quarter and 4.4% over the year. The expanded portfolio, which includes structured capital markets operations with credit risk and guarantees, reached R$708,201 million, up 2.8% quarterly and 3.7% in the annual comparison, with notable growth in securities (+6.6% quarterly and +7.9% in the annual comparison).

The customer funding balance reached R$670,430 million in December 2025, up 1.7% quarterly, mainly due to increases in repos, time deposits and LCI.
