Ordinary Shares financial

"security_title: "Ordinay Shares""

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.

open market or private transaction financial

"transaction_code_description: "Purchase in open market or private transaction""

units financial

"Footnote: "Includes 250 shares contained within units.""

Units are bundled securities sold as one package in a financing—commonly a share paired with an instrument that gives the holder the right to buy more shares later. For investors this matters because a unit’s extra component can change future supply of shares and potential returns, similar to buying a combo with a coupon that can be redeemed later and alter what you actually receive and what others might own.
