beneficial owner financial

"each of Linden Advisors and Mr. Wong may be deemed the beneficial owner of 1,150,000 Shares"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

separately managed accounts financial

"40,332 Shares held by the Managed Accounts (the "Managed Accounts")"

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.

dispositive power financial

"Shared power to dispose or to direct the disposition of: Linden Capital and Linden GP: 1,109,668"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.

voting power financial

"Shared power to vote or to direct the vote: Linden Capital and Linden GP: 1,109,668"

Voting power is the ability shareholders have to influence a company's major decisions—like electing the board, approving mergers, or changing corporate rules—based on the voting rights attached to the shares they hold. For investors it matters because greater voting power is like holding more keys to a building: it gives you a stronger say over management choices and the company’s strategy, which can affect future value and risk.

Power of Attorney regulatory

"duly authorized under Siu Min Wong's Power of Attorney, dated June 10, 2019"

A power of attorney is a legal document that allows one person to make decisions and act on behalf of another person, often in financial or legal matters. It’s like giving someone a trusted helper or agent the authority to handle important tasks if you are unable to do so yourself. This matters to investors because it can impact how their assets are managed or transferred if they become unable to oversee their affairs.
