Dear Sirs,

In connection with the relevant event of last May 6^th regarding the authorization by the Superintendency of Financial and Exchange Entities of the Central Bank of the Republic of Argentina for the payment of a dividend of AR $294,130,168,000, please be advised that on the date hereof the Board of Banco Macro S.A. resolved to apply the amount of AR $294,130,167,680 to the payment of a cash dividend in 3 equal and consecutive monthly instalments. The amount of each one of such instalments shall be paid in constant currency, using the most recently-published consumer price index (CPI) as determined by Instituto Nacional de Estadísticas y Censos (INDEC) to the date each instalment is made available to the shareholders.

Therefore, the Board fixed a preliminary payment Schedule as follows:

Year 2024
Instalment #	Available on (date)	Amount (i)
1	May 22^nd	$ 98,043,389,226.67
2	June 26^th	$ 98,043,389,226.67
3	July 22^nd	$ 98,043,389,226.67

(i)

The amount shall be expressed in constant currency to the date of the resolution that determines the availability of such instalments.

Each time the Board resolves to make available a dividend instalment, it shall issue the relevant notice of payment, containing the following information: i) the amount to be made available to the shareholders; ii) the amount per share; and iii) whether the dividend to be paid is subject to any kind of tax withholding.

In addition, please be advised that pursuant to Communique “A” 7997 of the Central Bank of the Republic of Argentina, in connection with the option to be granted to the non-resident shareholders to apply the funds derived from the dividends received to the acquisition of BOPREALs, the Bank shall inform such possibility at the time of issuing the relevant notice of payment of each dividend instalment.

The amount to be paid as dividend is subject to a 7% tax withholding under section 97 of the Argentine Income Tax Law as revised in 2019 and, in the case of non-resident shareholders who choose to acquire BOPREALs, an additional 17.5% tax withholding shall apply as Tax for an Inclusive and Solidarity-based Argentina (PAÍS) pursuant to Decree No. 385/2024.

Simultaneously with this notice, we publish the notice of payment of the first dividend instalment.

Sincerely,
