RSUs financial

"Represents RSUs granted pursuant to the Issuer's 2024 Equity Incentive Plan."

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

2024 Equity Incentive Plan financial

"Represents RSUs granted pursuant to the Issuer's 2024 Equity Incentive Plan."

contingent right financial

"Each RSU represents a contingent right to receive one share of common stock"

vest financial

"The RSUs vest on the earlier of 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.

continuous service financial

"subject to the Reporting Person's continuous service to the Issuer through such vesting date."
