Please inform the shareholders appointed to approve and sign the Meeting minutes.

The Board proposal to the Meeting will be that two of the shareholders attending the Meeting be appointed to sign the Minutes, jointly with the First Vice-President of the Board.

We inform that the Integrated Annual Report and the financial statements issued as of December 31, 2025 were published in the Argentine Securities Commission or “CNV” Online Information System (“AIF” or Autopista de Información Financiera) under ID No. 3490609 on March 6, 2026.

We also inform that the Bank submitted its financial statements in homogeneous currency - this in accordance with the accounting information framework established by the Argentine Central Bank (“BCRA”) through Communication "A" 6651 6849, as amended and supplemented, which established the mandatory application of such method as from the financial statements for fiscal years beginning on January 1, 2020 inclusive, and defined December 31, 2018 as the transition date. This situation is disclosed in Notes 2.1.5 to the consolidated financial statements as of December 31, 2025.

As mentioned in Note 2.1.5, IAS 29 requires the presentation of financial statements expressed in terms of the measuring unit at the end of the reporting period, when the functional currency of the entity corresponds to that of a hyperinflationary economy. To identify the existence of a hyperinflationary context, IAS 29 provides both qualitative guidelines and a quantitative guideline that consists of the cumulative inflation rate in the last three years reaching or exceeding 100%.

A series of indexes is used for the restatement of financial statements which is prepared and published monthly by the Argentine Federation of Professional Councils of Economic Sciences. This series combines the national Consumer Price Index (CPI) published by the National Institute of Statistics and Census (INDEC) starting from January 2017 (base month: December 2016) with the Wholesale Domestic Price Index (IPIM) published by INDEC up to that date. For the months of November and December 2015, for which INDEC did not disseminate information regarding the variation in the IPIM, the CPI variation for the Ciudad Autónoma de Buenos Aires was considered for calculation.

During the year ended 31 December 2025, the Board of Directors did not approve contracts with related parties pursuant to Section 73 of the Law 26.831.

The Financial Statements and the Board Integrated Annual Report referred to in the preceding answer give a full account of the management of BBVA Argentina Board of Directors, General Manager or Chief Executive Officer and Supervisory Committee.

The Board of Directors expects the Meeting to approve the proposal under item 5 of the agenda.

Regarding the distribution of Earnings, we hereby inform that the bank complies with the liquidity and solvency requirements set forth in Section 3 of the Central Bank's consolidated text on “Distribution of Results.

The Argentine Central Bank (BCRA) issued Communication "A" 6886 whereby  financial institutions must have the prior authorization of the BCRA for the distribution of their results.

The legal representative and/or any of the Directors of the Company will be authorized to sign the corresponding deed and carry out any procedure before the National Securities Commission and the Public Registry of Commerce in order to register said reform.

Sin otro particular, saludo a Uds. muy atentamente.
