performance units financial

"159,982 ordinary shares underlying performance units held by the Reporting Person."

Performance units are company awards that become valuable only if specified business targets are met; they typically convert into shares or cash when performance goals are achieved. Think of them like a conditional bonus that turns into stock only if the company hits agreed milestones, so they align managers’ incentives with shareholders’ interests and can affect future share count, executive pay expense, and investor returns.

Ordinary Shares financial

"This amount includes 159,982 ordinary shares underlying performance units"

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.
