private placement financial

"purchased 12,500 shares of the issuer's common stock from the issuer in a private placement at a price of $2.00 per share"

A private placement is a way for companies to raise money by selling securities directly to a small group of investors instead of through a public offering. This process is often quicker and less regulated, making it similar to offering a special, exclusive investment opportunity to select individuals or institutions. For investors, it can provide access to unique investment options that are not available on public markets.

voting and dispositive power financial

"Mr. Dey has voting and dispositive power over the shares held by such entity"

Common Stock financial

"On March 14, 2026, Mr. Dey purchased 12,500 shares of the issuer's common stock"

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.

open-market purchase financial

"transaction_action": "open-market purchase", "transaction_code_description": "Purchase in open market or private transaction""

An open-market purchase is when an investor or a company buys shares on a public stock exchange at the going market price, rather than through a private deal. It matters to investors because these purchases change how many shares are available, can push the stock price up or signal confidence from large buyers, and often affect per-share metrics like earnings—think of it like someone buying lots of apples off a grocery shelf, reducing supply and potentially raising the price.
