beneficially own financial

"Schonfeld may be deemed to indirectly beneficially own securities owned by the Schonfeld SMAs."

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.

sole voting power financial

"Sole Voting Power 781,678.00"

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

"Sole Dispositive Power 781,678.00"

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.

separately managed accounts financial

"assets of its private funds as separately managed accounts (the "Schonfeld SMAs")."

A separately managed account is an investment portfolio owned by a single investor but professionally managed to that investor’s specific goals and preferences, rather than pooled with other clients’ money. It matters to investors because it offers greater customization, tax control and transparency—like hiring a personal chef instead of eating from a shared buffet—though it often requires higher minimums and can have different fee and liquidity implications.

percent of class financial

"Percent of class: 5.33%"

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.
