restricted stock units ("RSUs") financial

"Represents an award of restricted stock units ("RSUs"). Each RSU represents a contingent right..."

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.

contingent right financial

"Each RSU represents a contingent right to receive one share of the Issuer's common stock..."

vesting financial

"100% of the total shares subject to the RSU fully vest on the first anniversary..."

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

settlement financial

"common stock upon the vesting and settlement of the RSU."

Settlement is the process of completing a financial transaction, like buying or selling a stock, by transferring money and ownership between parties. It ensures that both the buyer gets the asset and the seller gets paid, making the deal official. Without settlement, the transaction wouldn't be finalized or legally recognized.
