Restricted Stock Units financial
"Restricted Stock Units ("RSUs") convert into ARQQ ordinary shares on a one-for-one basis."
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
"The RSUs vest quarterly in equal installments on April 1, July 1, and October 1, 2026, and January 1, April 1, July 1, and October 1, 2027."
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.
derivative exercise/conversion financial

open-market sale financial
"transaction_action: "open-market sale" for 1,709 Ordinary Shares"
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
