Restricted Share Units financial

"Represents Class A ordinary shares, par value US$0.0001 per share (each, a "Class A ordinary share"), of BitFuFu Inc. (the "Company"), acquired by the reporting person upon vesting of the 17,500 out of 35,000 restricted share units"

Restricted share units (RSUs) are a promise from a company to give an employee or service provider actual shares or cash equal to the shares after certain conditions are met, typically staying with the company for a set time or hitting performance targets. Think of them like a time-locked gift card that becomes usable only after you’ve earned it. For investors, RSUs matter because they align employee incentives with company performance and can increase the number of shares outstanding over time, diluting existing ownership and affecting earnings per share.

Class A ordinary share financial

"Represents Class A ordinary shares, par value US$0.0001 per share (each, a "Class A ordinary share"), of BitFuFu Inc."

A Class A ordinary share is a type of common stock a company issues that carries a specific set of rights—most often particular voting power, dividend terms, or transfer rules—distinct from other share classes. For investors it matters because those rights affect control over company decisions, how income is paid out, and how easy shares are to buy or sell; think of it like a tiered ticket that gives different access and influence at the same event.
