restricted stock units ("RSUs") financial

"The reported securities are represented by restricted stock units ("RSUs"), of which the RSUs vests 100%"

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

Annual Meeting financial

"on the earlier of the one year anniversary of grant or the day immediately before the first 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.

continuous service financial

"after the grant date., subject to the Reporting Person's continuous service on each applicable vesting date."
