beneficially owns financial
"Vivo Opportunity, LLC beneficially owns 7,207,573 shares of Common Stock."
Beneficially owns means a person or entity enjoys the economic benefits and control of a security even if the legal title or registration is held in another name. Think of it like having the keys and profits from a car that is registered to a friend: you use it, benefit from it, and make decisions about it even though the official paperwork lists someone else. For investors, this matters because it reveals who truly controls shares, affects voting power, potential conflicts of interest, and regulatory disclosure obligations.
sole voting power financial
"5 | Sole Voting Power 7,207,573.00 6 | Shared Voting Power 0.00"
Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.
sole dispositive power financial
"7 | Sole Dispositive Power 7,207,573.00 8 | Shared Dispositive Power 0.00"
Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.
percent of class financial
"The percentage of class is based on 180,087,915 shares of Common Stock outstanding"
Percent of class is the portion of a specific category of securities—such as a company’s common shares, preferred shares, or a bond series—that takes part in or approves a corporate action (vote, consent, tender, etc.). Investors watch this number because it reveals how much support or opposition exists within that particular shareholder group; like counting how many members of a club back a proposal, it can determine whether a plan passes or how influence is distributed.
limited partnership financial
"Vivo Opportunity Fund Holdings, L.P. is a Delaware limited partnership."
A limited partnership is a legal business structure with two types of partners: at least one general partner who runs the business and bears full legal responsibility, and one or more limited partners who contribute money, share profits, and have liability capped at their investment. For investors, it matters because it separates control from financial exposure — like putting money into a store without managing it — and affects how returns, risks, taxes and transferability of ownership are handled.
