RSUs financial
"Consists of 21,239 shares of common stock and 7,632 RSUs."
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.
beneficially own financial
"may be deemed to beneficially own the shares held by ARCH VIII."
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.
pecuniary interest financial
"disclaim beneficial ownership of such securities, except to the extent of any pecuniary interest therein."
disclaims ownership financial
"The Reporting Person disclaims ownership of such shares, except to the extent of her pecuniary interest therein."
