4 terms

restricted stock units ("RSUs") financial

"Represents Ouster, Inc. (the "Company") restricted stock units ("RSUs")."

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 RSU represents a contingent right to receive one share of the Company's common stock."

vesting commencement date financial

"on each quarterly anniversary of March 11, 2026, the vesting commencement date"

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.

continued service financial

"subject to the reporting person's continued service through the applicable vesting date."
