Restricted Share Award financial

"Restricted Share Award which vests on May 21, 2027."

A restricted share award is a grant of company stock given to an employee or executive that only becomes permanent ownership if certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of it as a gift locked in a box that opens when the rules are satisfied; for investors, these awards can dilute existing shares and signal management’s incentives and confidence in future performance.

Ordinary Shares financial

"security_title: Ordinary Shares in the reported transaction."

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.
