Form 144 regulatory

"Filer Information | 144: Securities To Be Sold"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

Private Placement financial

"Common | 11/08/2019 | Private Placement"

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.

Pro-rata distribution financial

"08/15/2024 | Pro-rata distribution from Venture Fund"

A pro-rata distribution is when cash, shares, rights or other assets are divided among investors in proportion to their ownership stake, so each holder gets the same percentage of the total as their share of the company. Think of slicing a pie so everyone receives pieces sized to match how much of the pie they own. For investors this matters because it preserves relative ownership and determines how much value or new securities they receive, and whether they need to buy or sell to maintain their position.

Broker-dealer financial

"Stifel 501 N Broadway St Louis MO 63102"

A broker-dealer is a licensed firm or individual that both executes trades on behalf of clients (acting as a broker) and buys or sells securities for its own account (acting as a dealer). Investors care because broker-dealers provide the plumbing of markets — they place orders, hold or move cash and securities, offer research or advice, and their stability and fees directly affect trade execution, costs, and the safety of client funds; think of them as a combined travel agent and taxi for your investments.
