Restricted Stock Units financial
"Restricted stock units vest on March 1, 2027 (American Depositary Receipts)."
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.
American Depositary Receipts financial
"Restricted stock units vest on March 1, 2027 (American Depositary Receipts)."
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.
weighted average price financial
"The price reported in Column 4 is a weighted average price."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
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.
