Form 144 regulatory

"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.

proposed sale financial

"Common | 05/08/2026 | Option Granted - 02/16/2017 | Issuer"

gross proceeds financial

"38474 | 4161732.58"

The total amount of cash a company receives from a financing event or sale before any fees, expenses, taxes or deductions are taken out. Investors watch gross proceeds because it shows the raw scale of new capital being raised—think of it as the paycheck amount before withholdings—which helps assess how much funding is available for operations, growth, debt payoff or how much shareholder dilution might occur once costs are removed.

broker market

"Fidelity Brokerage Services LLC 900 Salem Street Smithfield RI 02917"

A broker is a licensed professional or firm that helps investors buy and sell financial assets by executing trades on their behalf, acting like a marketplace agent or matchmaker between buyers and sellers. Brokers matter to investors because they provide access to markets, handle order execution and paperwork, and can offer research or advice—services that affect trade speed, costs, and the quality of investment decisions.
