beneficially owned financial

"This figure includes 3,653,541 warrants beneficially owned by the Reporting Persons"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

Sole Voting Power regulatory

"5 | Sole Voting Power 0.00 6 | Shared Voting Power 4,153,541.00"

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.

Shared Dispositive Power regulatory

"8 | Shared Dispositive Power 4,153,541.00"

warrants financial

"includes 3,653,541 warrants beneficially owned by the Reporting Persons"

Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.

pecuniary interest financial

"disclaims beneficial ownership of the reported securities except to the extent of his or its pecuniary interest"
