___________________________________________________________________________ We address you to inform that, effective from 02/01/26, the Central Bank of the Argentine Republic (BCRA) will replace the text of Communication A 3500 to update the method for collecting data and calculating the Reference Exchange Rate (TCR). From that date, the current text of the aforementioned communication will be as follows:
1- The Central Bank of the Argentine Republic (BCRA) will determine the Reference Exchange Rate (TCR) daily by calculating the weighted average price of all operations considered according to the following criteria:
a. Amount: executed operations equal to or greater than USD 500,000 (five hundred thousand United States dollars). b. Currency: foreign transfer dollar against transfer pesos (UST$T).
c. Term: corresponding to the highest executed volume.
d. Characteristic: only visible and operable bids by all participants will be considered, excluding operations requested via quotation or channeled through foreign exchange brokers. 2- The calculation methodology is as follows:

-2- where:
= exchange rate price (ARS/USD) of each UST$T operation; = amount in United States dollars (USD) of the operation; and = total number of UST$T operations executed in the CAM1 round. On non-business days in the United States, the currency with the highest operated volume will be used, including foreign exchange MEP dollar against transfer pesos (USMEP) operations. 3- The BCRA will report daily via Communication C the resulting TCR in accordance with the prescribed procedure and publish it on its institutional website. 4- The BCRA Library will make available to interested parties information regarding the transactions from the 3rd (third) banking business day following the date on which the corresponding operations have been processed.
