Please be advised that the Shareholders’ Meeting held on the date hereof resolved to separate a portion of the Optional Reserve Fund for Future Profit Distributions, in order to pay a cash or in kind dividend, in the latter case valued at market price, or in any combination of both options, in the amount of AR$ 138,956,468,470 (amount expressed in constant currency as of 31 December 2025), which expressed in constant currency as of 28 February 2026 amounts to AR$ 147,101,261,954 and represents AR$ 217.33 per share, subject to prior authorization from the Banco Central de la República Argentina (BCRA). The above stated amount is subject to a 7% tax withholding under section 97 of the Income Tax Law as revised in 2019.

It is hereby stated that these consist of distributable profits obtained from realized earnings arising from the audited annual financial statements for the fiscal year beginning January 1st, 2025; that the amount approved for distribution complies with the maximum limit established by Communiqué “A” 8410 issued by the BCRA; and that the proposed dividend payment does not breach any commitments undertaken by the Bank.

Pursuant to the provisions of Communique “A” 8410, financial entities shall be able to distribute profits in 3 monthly equal and non-cumulative installments as from the third business day of May and of each month in which the payment is made. The amount of each dividend instalment shall be paid in constant currency as of the date of the shareholders' meeting.

Please be advised that for all references contained herein as to re-expressing any amounts in constant currency, the applicable rate shall be the national consumer price index (CPI) published by Instituto Nacional de Estadísticas y Censos (INDEC).

Accordingly, pursuant to the provisions of Communique “A” 7984 mentioned above, Banco Macro S.A. shall request the BCRA authorization for the distribution of the dividends approved by the Shareholders’ Meeting first above mentioned.

Sincerely,

Jorge F. Scarinci

Head of Market Relations
