WHEREAS: (i) Itaú Unibanco Conglomerate has continuously sought to rationalize the use of its resources and optimize its structures and businesses, with a view to providing greater efficiency and return on invested capital to its shareholders. Accordingly, on February 26, 2026, ITAÚ UNIBANCO HOLDING’s Board of Directors approved the proposal for a corporate restructuring for the merger of ITAUCARD into ITAÚ UNIBANCO HOLDING as further detailed below ("Merger" or "Transaction").
