Restricted Share Unit (RSU) financial

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

Class A Ordinary Share financial

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

A Class A ordinary share is a type of common stock a company issues that carries a specific set of rights—most often particular voting power, dividend terms, or transfer rules—distinct from other share classes. For investors it matters because those rights affect control over company decisions, how income is paid out, and how easy shares are to buy or sell; think of it like a tiered ticket that gives different access and influence at the same event.

Share Option financial

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

vests and becomes exercisable financial

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

annual meeting of shareholders financial

"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"

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.
