beneficially owned regulatory

"The aggregate amount beneficially owned by HC VIII Sponsor LLC consists of (i) 671,000 Class A Ordinary Shares..."

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
