"The RSUs will vest on the earlier of April 22, 2027 or the date of the Issuer's next Annual Meeting"

A company's annual meeting is a yearly gathering where owners (shareholders) and the board review performance, ask questions, and vote on key matters like electing directors, approving auditor choices, and sometimes setting pay or dividend policies. For investors it matters because decisions made and votes cast can change who runs the company, influence strategy and payouts, and affect the value or direction of their investment—similar to a homeowners’ meeting where rules and leaders that shape your property’s value are decided.

It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth.
