Explanation of Responses:

1. The reported securities represent units held by the reporting person in an institutional voluntary pension fund sponsored by the issuer and administered by a third-party manager. The fund is unitized and invests primarily in Grupo Cibest common and preferred shares, together with a small amount of liquid assets and cash. The reporting person does not have voting or investment discretion with respect to the assets held by the fund, and the issuer has determined the strategic asset allocation of the fund. Amounts attributable to the reported units are payable solely in cash upon withdrawal determined by reference to the value of the underlying fund assets on the date of withdrawal.

2. The instrument has no expiration date
