beneficially owns financial

"The Reporting Person beneficially owns 4,193,028 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.

Sole Voting Power financial

"Number of Shares Beneficially Owned by Each Reporting Person With: Sole Voting Power"

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

"Number of Shares Beneficially Owned by Each Reporting Person With: Sole Dispositive Power"

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.

Schedule 13D regulatory

"has previously filed a statement on Schedule 13D to report the acquisition"

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.

outstanding Common Stock financial

"representing approximately 29.9% of the outstanding Common Stock"

Outstanding common stock represents the total number of shares of a company's basic ownership that are currently held by all shareholders, including individual investors and institutions. It reflects how many pieces of the company are available to be owned, bought, or sold. This figure matters to investors because it influences the company's stock price, voting power, and how its value is divided among shareholders.
