Related Party Transactions financial

"Director and Related Party Transactions Group and Related Parties"

Transactions between a company and people or entities that have close ties to it—such as executives, board members, major shareholders, family members, or related companies—where the parties are not independent. These deals matter to investors because they can create conflicts of interest or hide favorable terms that distort a company’s true profits and risks; think of it like a business buying or selling to a family member instead of using the open market, which can lead to biased prices or undisclosed obligations.

CVM resolution 44/21 regulatory

"There were the following securities and derivatives operations, in accordance with CVM resolution 44/21"

Common Registered financial

"Security Description Quantity Common Registered 296.359"

Controlling Shareholder financial

"Controlling Shareholder ( ) People connected to the management"

A controlling shareholder is a person or entity that holds enough voting power in a company—often a majority of votes or decisive influence through agreements—to determine its board, strategy and major decisions. For investors this matters because that control shapes corporate direction, risk and who benefits from deals; like a driver steering a car, a controlling shareholder can speed up or block changes, which can affect minority shareholders’ returns and the company’s value.

Fiscal Council financial
