Equity Incentive Plan financial

"defined in the Issuer's 2021 Equity Incentive Plan"

An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.

Vesting Commencement Date financial

""Vesting Commencement Date" shall mean April 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.
