RSUs financial

"RSUs granted to the Reporting Person under the Issuer's Amended and Restated 2021 Equity Incentive Plan."

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.
