beneficial owner financial

"Group One Trading LLC may be deemed to be the beneficial owner of 9,445,376 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.

Sole Voting Power financial

"5 | Sole Voting Power 9,445,376.00 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 9,445,376.00 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.

market maker financial

"Group One Trading LLC is a market maker in the options listed on POET Technologies Inc."

A market maker is a firm or individual that stands ready to buy and sell a particular stock or other security throughout the trading day, posting prices at which it will transact so buyers and sellers can trade quickly. Think of it as a shopkeeper who keeps inventory and posts prices to ensure someone can always buy or sell; this reduces delays, narrows price swings, and helps investors execute trades at fairer, more predictable prices.

CUSIP financial

"(e) | CUSIP Number(s): 73044W302"

A CUSIP is a nine-character alphanumeric code that uniquely identifies a U.S. or Canadian financial security—such as a stock, bond, or fund share—like a Social Security number for an investment. It matters to investors because brokers, exchanges and record-keepers use the CUSIP to match trades, track ownership, settle transactions and pull accurate records, reducing errors and ensuring money and securities go to the right place.
