Share Options (Right to Buy) financial

"security titled “Share Options (Right to Buy)” was granted to the director"

Ordinary Shares financial

"underlying security title is stated as Ordinary 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.

exercise price financial

"options have an exercise price of $0.025 per share"

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.

vested financial

"The share options are immediately fully vested, but are not exercisable"
