5 terms

restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs") granted on March 31, 2026, which vest"

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 in sixteen equal quarterly installments financial

"which vest in sixteen equal quarterly installments over four years"

vesting commencement date financial

"over four years with a vesting commencement date of January 1, 2026."

The vesting commencement date is the starting point when an employee begins earning ownership rights to their promised benefits, such as stock options or retirement contributions. Think of it like the day a savings account is opened—only after this date do the benefits start to grow and become fully available over time. It matters to investors because it marks when the clock begins ticking toward full ownership, affecting the timing and value of these benefits.
