Restricted Stock Units financial

"Each restricted stock unit ("RSU") represents a contingent right to receive one share of the Issuer's Common Stock."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

RSUs vested in full financial

"The RSUs vested in full on June 18, 2026."

stock option financial

"The option vests and becomes exercisable in twelve (12) substantially equal monthly installments following June 18, 2026..."

A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
