beneficial owner financial

"WAM may be deemed the beneficial owner of 4.89% of the Issuer's outstanding Ordinary 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.

shared power to vote or direct the vote financial

"WAM has shared power to vote or direct the vote of 495,488 of the Issuer's ordinary shares"

dispositive power financial

"Each of Wolverine Holdings, Mr. Bellick, and Mr. Gust have voting and dispositive power over 495,488"

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.
