Restricted Stock Units ("RSUs") financial

"The Restricted Stock Units ("RSUs") were granted on May 19, 2026"

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.

vesting financial

"100% of the total number of RSUs granted shall vest on the first to occur"

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.

contingent right financial

"Each RSU represents a contingent right to receive one share of common stock"
