% compared to 2Q25. This reduction is explained by a release of COP 266 billion resulting from models calibration and lower expense across all segments except for Bancolombia’s corporate segment, due to the recognition of provisions for certain specific clients classified in stage 2.

Provisions as a percentage of average gross loans, quarterly annualized, were 1.18% in 3Q25 and 1.42% over the last 12 months, implying a decrease of 39 and 97 basis points, respectively, reflecting a lower expected loss outlook. Meanwhile, loan loss provisions (for the principal) totaled 12,963 billion, which, although lower than the previous quarter, represents adequate coverage equivalent to 4.7% of gross loans.

General expenses totaled COP 2,052 billion in the quarter, which represented a decrease of 3.0% compared to the previous quarter and an increase of 6.0% versus 3Q24. The quarterly reduction was largely due to lower stamp tax payments and a decrease in expenses related to the corporate evolution towards Grupo Cibest. Likewise, the annual increase was mainly attributable to expenses linked to the corporate evolution towards Grupo Cibest, as well as higher licensing and technology maintenance costs.
