Restricted Stock Units financial

"security_title: "Restricted Stock Units" with exercise or conversion into common stock"

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.

cash settlement financial

"Represents the cash settlement on May 19, 2026 of RSUs granted on May 19, 2025."

Cash settlement is a process where, instead of exchanging physical assets like stocks or commodities, the parties involved settle the difference in value with money after a contract ends. For investors, it simplifies transactions by avoiding the need to handle or deliver the actual asset, making it quicker and more convenient to complete trades. This method ensures a straightforward way to settle agreements based on their final value.
