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 shares financial

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

Class A ordinary shares are a type of ownership stake in a company that typically grants voting rights to shareholders, allowing them to have a say in important company decisions. They often come with priority in receiving dividends or profits, making them attractive to investors seeking influence and potential income. These shares help distinguish different levels of ownership and rights within a company's stock structure.

RSU financial

"Each RSU represents a contingent right to receive one Class A ordinary share."

Restricted stock units (RSUs) are a form of company shares given to employees as part of their compensation, usually with certain restrictions or conditions, such as remaining with the company for a set period. When these restrictions lift, employees receive actual shares that they can sell or hold. For investors, RSUs can impact a company's stock supply and reflect the company's commitment to attracting and retaining talent.
