Restricted stock units ("RSUs") financial

"Restricted stock units ("RSUs") issued pursuant to the 2021 Equity Incentive Plan"

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.

2021 Equity Incentive Plan financial

"RSUs issued pursuant to the 2021 Equity Incentive Plan (the "2021 Plan")"

grantor retained annuity trust financial

"contributed to grantor retained annuity trust ("GRAT 1")"

A grantor retained annuity trust (GRAT) is an estate-planning tool where the person who creates the trust transfers assets into it but receives fixed cash payments (an annuity) from the trust for a set number of years; whatever remains after that term passes to designated beneficiaries. It matters to investors because it can shift future appreciation of assets out of the creator’s taxable estate—like putting an asset into a timed vending machine that pays you fixed amounts while any extra value that grows inside the machine goes to heirs with reduced gift or estate tax consequences.

Continuous Service financial

"subject to the Reporting Person's Continuous Service (as defined in the 2021 Plan)"

annual meeting of stockholders financial

"fully vested on the earlier of (i) the one-year anniversary ... or (ii) the date of the Issuer's next annual meeting of stockholders"
