beneficial owner financial

"Each of the Reporting Persons may be deemed to be the beneficial owner of approximately 5.18%"

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.

sole voting power financial

"Each of the Reporting Persons has the sole power to vote or to direct the vote of 818706 shares."

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.

dispositive power financial

"sole power to dispose or to direct the disposition of 818706 shares."

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.

investment manager financial

"BAM, the direct holder of 818,706 shares... BAM may be deemed to exercise voting and investment power"

exempted company financial

"ADMF, a Cayman Islands exempted company that is an investment management client of BAM"
