restricted stock unit (RSU) financial

"Each share is represented by a restricted stock unit (RSU)."

A restricted stock unit (RSU) is a promise from a company to give an employee company shares (or cash equal to their value) at a future date if certain conditions are met, such as staying with the company or hitting performance targets. For investors, RSUs matter because when they convert into actual shares they increase the number of shares available and can create selling pressure as employees cash out—think of them as a future paycheck paid in company stock.

Class A Common Stock financial

"Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock upon settlement."

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.

Continuous Service financial

"subject to the Reporting Person's Continuous Service (as defined in the 2021 Equity Incentive Plan) through the applicable vesting date."
