3 terms

restricted stock units (RSUs) financial

"Represents the grant of restricted stock units (RSUs). Each RSU represents a contingent right"

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

Continuous Service financial

"will vest quarterly thereafter, subject to the Reporting Person's Continuous Service"

2025 Equity Incentive Plan financial

"Continuous Service (as defined in the Issuer's 2025 Equity Incentive Plan)."
