Schedule 13G regulatory

"This is being filed on behalf of ... the "Reporting Persons"."

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

beneficial ownership financial

"Other than those securities reported herein as being held directly by such Reporting Person, each Reporting Person disclaims beneficial ownership"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

shared voting power financial

"Shared Voting Power 1,906,809.00 7 | Sole Dispositive Power 0.00 8 | Shared Dispositive Power"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

dispositive power financial

"Sole Dispositive Power 0.00 8 | Shared Dispositive Power 1,906,809.00"

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.

pecuniary interest financial

"disclaim beneficial ownership of the reported securities held by U.S. Venture Partners, except to the extent of any pecuniary interest therein."

Rule 13d-1(k)(1) regulatory

"to file jointly in accordance with the provisions of Rule 13d-1(k)(1) under the Act"
