beneficially owns financial

"Through the Trust the Reporting Person beneficially owns 8,475,258 shares of Common Stock"

Beneficially owns means a person or entity enjoys the economic benefits and control of a security even if the legal title or registration is held in another name. Think of it like having the keys and profits from a car that is registered to a friend: you use it, benefit from it, and make decisions about it even though the official paperwork lists someone else. For investors, this matters because it reveals who truly controls shares, affects voting power, potential conflicts of interest, and regulatory disclosure obligations.

Series A Preferred Stock financial

"16,000 shares of Series A Preferred Stock of the Issuer"

Series A preferred stock is a type of ownership share in a company that gives investors certain advantages, such as priority in receiving profits or getting their money back if the company is sold or goes bankrupt. It is often issued during early funding stages to attract investors by offering more security than common shares. This stock matters to investors because it provides a safer way to invest while still holding potential for future gains.

Schedule 13D regulatory

"This Amendment No. 22 amends and supplements the original filed by the Reporting Person on Schedule 13D"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

dispositive power financial

"may be deemed to have the sole power to vote or direct the vote, and sole power to dispose"

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.

open market financial

"acquired 65,258 shares of Common Stock of the Issuer on the open market for $1.00 per share"

An open market is a system where buying and selling of goods, services, or financial assets happen freely without restrictions or special controls. For investors, it means they can trade assets easily and quickly, which helps determine fair prices based on supply and demand. This environment encourages transparency and competition, making it easier to buy or sell with confidence.

personal funds financial

"All shares of the Issuer's Common Stock acquired by the Reporting Person were acquired with personal funds"
