restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs") granted pursuant to the Issuer's 2022 Equity Incentive Plan."

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.

vest financial

"The RSUs will vest 25% on the first anniversary of the date of grant."

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

quarterly installments financial

"The remaining shares shall vest in 12 equal quarterly (every 3 months) installments thereafter."
