Beneficial Ownership Maximum financial

"the Reporting Person would beneficially own, after any such issuance or exercise, more than 9.99% of the then issued and outstanding shares of the issuer's common stock (the "Beneficial Ownership Maximum")"

Prefunded Warrants financial

"Excludes (i) 127,007,616 shares of common stock underlying prefunded warrants ("Prefunded Warrants")"

Prefunded warrants are a security that gives the holder the right to convert the warrant into a share after paying a very small remaining amount because almost the full purchase price was paid upfront. They matter to investors because exercising them increases the company’s outstanding shares (dilution) and can provide immediate cash to the issuer while allowing holders to bypass ownership limits or simplify timing, similar to buying a nearly-complete gift card that only needs a tiny top-up to use.

Series B preferred stock financial

"shares of common stock issuable upon conversion of 517,559 shares of Series B preferred stock ("Preferred Stock")"

Series B preferred stock is a type of ownership share issued by a company that offers certain advantages over common stock, such as priority in receiving dividends or assets if the company is sold or liquidated. It is typically issued after an initial round of funding, making it a way for investors to support a company's growth while gaining some protections and benefits. This stock matters to investors because it often provides a more secure investment position with potential for future growth.

beneficially owned financial

"Amount beneficially owned: 45,339,650. Excludes (i) 127,007,616 shares of common stock underlying prefunded warrants"

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.

dispositive power financial

"Sole power to dispose or to direct the disposition of: 45,339,650."

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.
