Form 3 regulatory
"This Form 3 is being filed jointly by BRC, B. Riley Principal Capital, LLC"
Form 3 is the initial public filing that officers, directors and large shareholders must submit to report their ownership of a company’s securities when they become insiders. It acts like an opening inventory sheet that gives investors a starting point to see who holds significant stakes and to spot later trades or potential conflicts of interest, helping assess insider confidence and transparency.
beneficially own financial
"As a result, BRC may be deemed to indirectly beneficially own the 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.
pecuniary interest financial
"disclaims beneficial ownership of the outstanding shares of Common Stock reported herein, except to the extent of its/his respective pecuniary interest"
private placement financial
"acquired 460,080 shares of the Issuer's common stock at a purchase price of $1.60 per share in private placement by the Issuer"
A private placement is a sale of securities directly to a selected group of investors, typically institutions or accredited investors, instead of through a public offering. It lets a company raise money faster and with fewer regulatory steps; for existing shareholders it matters because the newly issued shares, often sold at a discount, increase the share count and can dilute their ownership.
Securities Purchase Agreement regulatory
"pursuant to the terms of a Securities Purchase Agreement dated August 20, 2026"
A securities purchase agreement is a written contract between a buyer and a seller outlining the terms for buying or selling financial assets such as stocks or bonds. It specifies details like the price, quantity, and conditions of the transaction, similar to a shopping list with agreed-upon terms. For investors, it provides clarity and legal protection when transferring ownership of these financial instruments.
