Restricted Stock Units financial

"security_title": "Restricted Stock Units""

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

open-market sale financial

"transaction_action": "open-market sale""

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

preferred shares financial

"security_title": "Preferred shares""

Preferred shares are a type of investment that gives investors priority over common shareholders when it comes to receiving dividends and getting their money back if a company is sold or liquidated. Think of them as a safer, more predictable way to earn income from a company's profits, similar to a fixed-return investment, but without voting rights. This makes preferred shares appealing to those seeking stable income with a higher claim on assets than regular stockholders.

currency translation financial

"translated into U.S. dollars at the April 10, 2026 selling rate"

exchange rate financial

"selling rate of R$5.0229 per US$1.00"

Exchange rate is the price of one currency expressed in another—for example, how many euros you receive for one US dollar. It matters to investors because changes in that price alter the reported profits, costs and value of assets for companies and portfolios that operate or hold money across borders; think of it like switching measurement units, where the same item can look bigger or smaller depending on the unit used.
