We address you to inform that this Institution has adopted the resolution which, in its pertinent part, establishes: “1- Order, effective from 18/08/25, the modification of the calculation for compliance with the integration of minimum cash in pesos, shifting from the current method –measured based on the average daily balances of admitted items– to a daily measurement, leaving without effect the carryover options provided for in point 1.7. and maintaining those provided for in point 7.9. of the consolidated text on Minimum Cash. The numerical values of any integration deficiency measured on average up to the day prior to the effective date established in the preceding paragraph must be integrated proportionally over the remaining days of the current month, in addition to 100% (one hundred percent) of the requirement corresponding to each day. Potential integration excesses –in the proportions admitted for integration– recorded up to that date may also be carried over proportionally until month-end, reducing the numerical values of the requirement for the remaining days of the month. 2- Establish that minimum cash integration deficiencies (point 3.1.1. of the consolidated text on Minimum Cash) and excesses in the net foreign currency position (3.1. of the consolidated text on Net Foreign Currency Position) will be subject to a charge in pesos equivalent to 3 (three) times the total Argentine Wholesale Rate (TAMAR) of banks, according to the methodology set forth in the respective consolidated texts. 3- Leave without effect point 3.2.1. of the consolidated text on Minimum Cash regarding integration in pesos. 4- Increase by 5 (five) percentage points, effective from 19/08/25 to 28/11/25, the minimum cash requirement rates applicable to demand deposits set forth in points 1.3.1.1., 1.3.2.1. and 1.3.3.1. of the consolidated text on Minimum Cash, as well as to peso deposits, demand and term investments with early redemption option from the day the investor may exercise that option, which constitute the assets of common money market funds (money market), passive repos and passive stock exchange pledges, both in pesos, as provided by Communication A 8289. This additional requirement will apply to financial entities of group A and branches or subsidiaries of G-SIBs not included in that group, and may be integrated with peso government bonds issued by the National Treasury that are acquired in primary subscription from 18/08/25 in special tenders for financial entities.

-2- Additionally, all entities may, effective 19/08/25, integrate with peso government bonds issued by the National Treasury acquired in primary subscription from 18/08/25 in special tenders for financial entities up to 3 (three) percentage points of the rates provided for demand deposits in points 1.3.1.1., 1.3.2.1. and 1.3.3.1. of the consolidated text on Minimum Cash.” Likewise, we inform you that we will subsequently send you the sheets that, replacing those duly provided, must be incorporated into the referenced consolidated texts.
