Large AR$ cash dividend confirmed with record and pay dates set.

Banco Macro confirms instalment No. 5 of its cash dividend at AR$ 36,589,874,132.56, or AR$ 57.2261951351 per share. The notice is labeled complementary because recent treasury share repurchases adjusted the share count used for distribution.

Key mechanics include the 10/29/2025 record date and availability on 10/31/2025. The filing states a 7% withholding under the Income Tax Law, which reduces cash received by certain holders. ADR holders receive payment via BNY Mellon per the depositary agreement.

Further repurchases through close of business on the record date could prompt a supplementary notice. Actual cash outflow depends on final eligible shares at the record date; the excerpt provides the stated gross amount and per-share figure.
