Restricted Stock Units financial

"On July 1, 2026, the reporting person was granted 47,655 RSUs, of which 16,621 vested upon the date of grant..."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

RSUs financial

"Represents the conversion upon vesting of restricted stock units (RSUs) into Class A Common Stock."

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

economic equivalent financial

"Each restricted stock unit is the economic equivalent of one share of Sidus Space, Inc.'s Class A Common Stock."

Class A Common Stock financial

"Represents the conversion upon vesting of restricted stock units (RSUs) into Class A Common Stock."

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.
