Significant Ownership Interest financial
"Announcement to the Market Significant Ownership Interest Itaú Unibanco Holding S.A."
American Depositary Receipts financial
"owners of preferred shares and American Depositary Receipts representing approximately 4.97%"
A certificate traded on U.S. markets that represents ownership of shares in a foreign company, letting U.S. investors buy and sell that company as if it were listed domestically. Think of it as a local voucher for a foreign product: it makes price quotes in dollars, trades on familiar exchanges, and brings differences in liquidity, fees and legal protections that can affect returns and risk compared with buying the underlying foreign shares directly.
CVM Resolution 44/21 regulatory
"in compliance with Article 12 of the Brazilian Securities Commission (“CVM”) Resolution No. 44, dated august 23, 2021"
minority investment financial
"This is a minority investment not intended to change the control or administrative structure of the Company."
A minority investment is when an investor buys less than half of a company's shares or voting rights, so they have a financial stake but not control over management or major decisions. It matters to investors because it offers potential upside from the company's growth without the responsibilities of running it, but also limits influence over strategy and exposes the investor to risks and exit constraints similar to being a passenger rather than the driver.
proxy voting rights financial
"GQG Partners also informs you that it does not hold proxy voting rights on behalf of its clients."
