Performance-Based Restricted Share Units financial

"Represents Ordinary Shares issued upon the vesting and settlement of Performance-Based Restricted Share Units"

Performance-based restricted share units are promises to give company stock to employees or executives only if the business hits specified targets, such as revenue, profit or stock performance; think of them as a bonus paid in shares that only vests when certain goals are met. They matter to investors because they align management incentives with shareholder outcomes, can dilute share count when paid out, and reveal how leadership is being rewarded and what milestones the company expects to reach.

Performance Share Units financial

"Performance Share Units granted on September 11, 2023 vested and were settled in Ordinary Shares"

Performance share units are a type of company stock award given to employees that depend on the company meeting specific goals or targets. If these goals are achieved, the employee receives shares or the value of shares; if not, they may receive little or no compensation. This aligns employees’ interests with the company's success and encourages performance that benefits investors.
