#### Net Interest Income & Net Interest Income
Net interest income totaled COP 5,302 billion in 3Q25, representing an increase of 1.5% compared to 2Q25 and 2.9% compared to 3Q24. This growth was mainly due to a greater reduction in interest expenses relative to the decline in interest income, which was supported by the strong performance of interest income from debt instruments and the valuation of financial instruments, reaching COP 756 billion, a variation of 12.5% compared to the previous quarter. This change was primarily driven by higher yields on debt securities, associated with liquidity portfolio management.

On the other hand, interest income from the loan portfolio decreased during the quarter, mainly due to a reduction in income from the mortgage portfolio, this was particularly evident in loans indexed to the inflation-linked UVR 1 rate at Bancolombia S.A., driven by slower growth in the UVR value compared to the previous quarter. In contrast, interest income from commercial and consumer loans portfolios showed a slight increase over the same period.

Meanwhile, interest expenses decreased by 2.3% compared to the previous quarter and by 10.5% compared to 3Q24. This quarterly variation was mainly explained by lower yields on savings accounts and time deposits at Bancolombia S.A.

The annualized weighted average cost of deposits was 4.05% in 3Q25, representing a decrease of 13 basis points compared to 2Q25. During this quarter, Bancolombia S.A., Banco Agricola, and Banistmo reduced their cost of deposits, while Bam, on the other hand, recorded an increase linked to its strategy of boosting funding through savings accounts.

As a result, the loan portfolio NIM was 6.98% for the quarter, decreasing by 8 basis points compared to 2Q25 and by 18 basis points compared to 3Q24. The investment NIM stood at 4.21%, representing an increase of 82 basis points over 2Q25. Finally, the consolidated NIM registered an increase of 2 basis points in the quarter, rising from 6.57% to 6.59%, although it showed a decrease of 24 basis points compared to the previous year.
