SUZ · Suzano S.A.

This 6-K reports the outcomes of Suzano’s Annual and Extraordinary General Shareholders’ Meetings held on April 23, 2026 — a high-materiality corporate governance event reflecting investor ratification of 2025 performance and strategic direction. The near-unanimous approval of financial statements and management accounts (with over 85% of votes in favor and minimal opposition) signals strong shareholder confidence in the Company’s operational execution and financial reporting integrity for the fiscal year ended December 31, 2025. The dividend resolution is particularly consequential: R$1.385 billion in mandatory minimum dividends was approved, reinforcing Suzano’s commitment to disciplined capital return — notably, R$1.38 billion had already been distributed as interim dividends in February 2026, while the remaining R$5.63 million constitutes an additional dividend payable by year-end 2026, unadjusted for inflation. Governance enhancements were also affirmed, including the formal installation of a three-member Fiscal Council — triggered by a >2% shareholder petition — and the classification of four directors as independent, satisfying B3 Novo Mercado listing requirements and strengthening oversight capacity. The election of a nine-person Board, led by Chairman David Feffer and supported by two Vice-Chairmen, preserves continuity in leadership while embedding structural independence. Collectively, these resolutions validate Suzano’s adherence to Brazilian corporate law, regulatory compliance frameworks (CVM Resolutions 70/22, 80/22, 81/22), and Novo Mercado governance standards — all critical for investor trust, especially among international holders reliant on transparent, rule-based stewardship.
