"PWAM, as investment manager to the PW Funds, may be deemed to beneficially own 6,019,695 Equity Shares"
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.
Series E Convertible Preferred Stockfinancial
"as well as Series E Convertible Preferred Stock convertible into 757,888 Equity Shares"
Series E convertible preferred stock is a class of investment shares issued in a later-stage financing round that behave like a hybrid between a safety-first claim and an option to become ordinary shares. Think of it as a VIP ticket that gives owners priority on payments and protections if things go wrong, but can be swapped for regular shares later—important to investors because it affects payout priority, potential dilution of ownership, voting power, and the company’s implied valuation.
Subordinate voting shares are a type of company stock that typically carry fewer voting rights than regular shares, meaning holders have less influence over company decisions. They are often used to raise capital while allowing founders or main shareholders to retain control. For investors, understanding the difference helps assess their level of influence in company decisions and the potential risks or benefits of holding different types of shares.
Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.
Schedule 13Gregulatory
"This report on (this "") is being jointly filed by"
A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.
