restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs") awarded under the Issuer's 2023 Stock Option and 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.

2023 Stock Option and Incentive Plan financial

"RSUs awarded under the Issuer's 2023 Stock Option and Incentive Plan"

Series A Common Stock financial

"each representing the contingent right to receive one share of the Issuer's Series A Common Stock"

Series A common stock is a specific class of a company’s ordinary shares issued during an early formal funding round, carrying the ownership rights and voting power tied to that class. For investors it signals an early-stage equity claim with potential upside if the business grows, but also greater risk and typically less liquidity than shares in mature, publicly traded firms—imagine buying a seat on a startup’s team before the company has proven itself.
