In the fiscal year 2016 such optional reserve fund was adjusted in AR$ 368,546,288.56, since the BCRA authorized the payment of a cash dividend of AR$ 227,708,000 for the year 2014, which was paid in March 2016. During the 2025 fiscal year, the reserves were applied in the amount of AR$ 171,727,125.17 resulting from the treasury stock acquisition, pursuant to the Board of Directors' resolution dated October 8, 2025.

Pursuant to the provisions of the Financial Entities Act No. 21526, each year the Bank must apply to the legal reserve fund the proportion of its annual earnings that the BCRA shall determine, which shall neither be less than 10% nor more than 20%.

The amounts arising from item 4 of the Agenda are restated in constant currency as of December 31, 2025, and shall not be restated as of the date of the Shareholders’ Meeting.

The optional reserves, created by the above mentioned shareholders’ meetings, are reasonable and are the result of a prudent administration under the provisions of subsection 3, Section 66 of the General Companies Act.

The request of authorization for the payment of dividends shall be submitted to the BCRA once the distribution is approved by the Shareholders’ Meeting.

As a financial institution, the Bank is subject to the rules of the BCRA, which does not provide that the distribution of profits shall be updated in the currency of the date of the Shareholders' Meeting.

Additionally, please be advised that as mentioned in item 5 of the Agenda, the motion to delegate powers to determine the time, currency, terms and other payment terms and conditions, shall be the responsibility of the Board as governing body.
