Restricted Share Unit financial

"Each Restricted Share Unit (RSU) represents a contingent right to receive one Class A Ordinary Share of the Issuer."

A restricted share unit (RSU) is a promise by a company to give an employee a set number of company shares at a future date, typically after meeting time or performance conditions. For investors, RSUs matter because when they convert into actual shares they increase the number of shares outstanding (like unlocking more tickets in a game), which can dilute existing holders, and they align employee incentives with company performance, influencing behavior and long-term value.

Share Option financial

"The option vests and becomes exercisable in twelve substantially equal monthly installments following the date of the grant."

vests in their entirety financial

"The RSUs vest in their entirety on the earlier of a) the anniversary of the date of the grant and b) the date of the Issuer's annual meeting of shareholders in the following year."

annual meeting of shareholders financial

"the date of the Issuer's annual meeting of shareholders in the following year."

A yearly gathering where a company’s owners (shareholders) vote on key items like electing the board, approving executive pay, and ratifying auditors, and receive updates on performance and strategy. Think of it as an annual town hall for owners: it matters to investors because outcomes and disclosures can affect leadership, corporate direction, dividend and governance policies, and therefore the company’s risk and potential return.
