5 terms

beneficially own regulatory

"As of the date hereof, Mr. Schmalz and Mrs. Schmalz beneficially own, in the aggregate, 100,394 shares"

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

subscription offering market

"purchased 8,500 shares for a purchase price of $10 per share in a subscription offering"

A subscription offering is a company’s sale of new securities that investors agree to buy in advance, similar to signing up for a magazine subscription where you commit to receive future issues. It matters to investors because it changes how many shares exist and who owns them, and it provides the company with cash for growth, debt repayment or other plans—outcomes that can raise or lower the value of existing holdings.

sole voting and dispositive power regulatory

"Mr. Schmalz has sole voting and dispositive power with respect to 24,153 shares"

shared voting and dispositive power regulatory

"has shared voting and dispositive power with respect to 76,241 shares of the Issuer's Common Stock"

Schedule 13D regulatory

"If the filing person has previously filed a statement on Schedule 13G 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.
