restricted stock units ("RSUs") financial

"The Reporting Person was granted restricted stock units ("RSUs"), each of which represents a contingent right to receive one share"

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 of which represents a contingent right to receive one share of ordinary stock"

vesting financial

"2,460 are already vested and the remaining 2,460 will vest on 07/31/2026"

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.

ordinary stock financial

"receive one share of ordinary stock of Tower Semiconductor Ltd."

continued service financial

"will vest on 07/30/2027, subject to the Reporting Persons continued service through each vesting date"
