It also delegated to the Board of Directors the approval of the repurchase rules under which the administration was authorized to execute said program. Based on the above, on July 17, 2025, the repurchase program began in Colombia on the trading systems of the Colombian Stock Exchange through Valores Bancolombia S.A.
