Stock Option (right to buy) financial

"security_title: Stock Option (right to buy)"

Vesting Commencement Date financial

"following the Vesting Commencement Date, with the first vesting 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.

Continuous Service financial

"subject to your Continuous Service through each such vesting date"

stockholder-approved share reserve financial

"based on the then-current stockholder-approved share reserve thereunder"

Option Agreement financial

"Subject to the terms of the Option Agreement, one-twelfth"

An option agreement is a contract that gives one party the right, but not the obligation, to buy or sell a specific asset (like company shares or property) at a pre-agreed price within a set time period. Think of it like a reservation or ticket that holds a purchase at today’s terms for later — it matters to investors because it can create potential future value or liability, change ownership stakes, and affect share dilution and company control.
