Declaration of Voting Results & Voting Rights Announcements Classification · 95% confidence The document is titled 'MAPA FINAL DE VOTAÇÃO DETALHADO ASSEMBLEIA GERAL ORDINÁRIA E EXTRAORDINÁRIA DE 23.04.2026' which translates to 'Final Detailed Voting Map of the Ordinary and Extraordinary General Meeting of 23.04.2026'. It contains detailed voting results from shareholders on various agenda items, including approval of financial statements and allocation of results for the fiscal year ended December 31, 2025.

Therefore, the document fits the category 'Declaration of Voting Results & Voting Rights Announcements' (DVA). The document length (15,000 characters) and content confirm it is the actual voting results, not just an announcement of a report publication or a regulatory filing.
