Dividend and capital structure analyst

Banco Macro details a large cash dividend instalment with clear timing and tax treatment.

Banco Macro S.A. is proceeding with instalment No. 4 of a dividend totaling AR $35,845,730,979.60, equivalent to AR $56.0603367572 per share and stated as 5,606.0336% of capital stock of AR $639,413,408. The filing links this distribution to prior shareholder approvals and specific Central Bank authorizations, indicating the payout structure has been vetted by regulators.

The dividend is distributed in 10 equal monthly instalments expressed in constant currency, which helps maintain the real value of each payment in an inflationary environment. A 7% withholding tax applies to the aggregate amount under section 97 of the Income Tax Law, meaning the net cash received by investors will be lower than the gross dividend figure.

Operationally, local shareholders can collect through Caja de Valores S.A. from 09/29/2025, using the record date of 09/26/2025, while ADR holders rely on The Bank of New York Mellon to pass through the distribution on the underlying Class B shares. Future company disclosures may clarify how this multi-instalment structure fits into ongoing capital management.
