Shareholders’ Agreement financial
"the provisions of the Company’s Shareholders’ Agreement, entered into on December 19, 2025"
A shareholders’ agreement is a private contract among a company’s owners that sets out their rights, responsibilities and how key decisions will be made—think of it as the house rules for people who own slices of the same business. It matters to investors because it controls voting rights, limits how shares can be sold or passed on, and lays out what happens in disagreements, so it affects control, liquidity and the value of an investment.
capital reduction financial
"completion of the first capital reduction of Suzano Holding S.A."
A capital reduction is a legal move where a company shrinks the amount of money recorded as its official share capital, either by cancelling shares, lowering the value of each share, or returning cash to shareholders. Investors care because it changes the company’s balance sheet and can alter how much each remaining share represents—like pruning a tree to concentrate fruit or giving back some of the harvest—potentially affecting ownership percentages, per‑share metrics and the stock’s market value.

Comissão de Valores Mobiliários regulatory
"Brazilian Securities and Exchange Commission (Comissão de Valores Mobiliários – CVM)"
A securities commission is a government agency that oversees the buying and selling of stocks, bonds and other investment products to ensure markets are fair, transparent and lawful. Think of it as the market’s referee and rulemaker: it sets disclosure rules, investigates fraud and can sanction bad actors, which helps investors trust that companies report accurate information and that markets operate smoothly. That oversight affects investment risk and confidence.
