Performance Rights financial
"The CEO also holds 1,778,734 Performance Rights that vest upon achievement of performance milestones"
Performance rights are conditional awards that give employees or executives the promise of receiving company shares or cash only if the business meets specific targets or survives for a set period. They work like a bonus you only get when certain goals are hit, so they matter to investors because they can increase the number of shares outstanding (dilution), signal management’s incentives and confidence in future results, and affect per-share earnings and valuation.
Options financial
"He also holds options over 1,430,000 Ordinary Shares with a USD exercise price"
Options are contracts that give investors the right to buy or sell an asset at a specific price within a certain time frame. They function like a reservation or a ticket that allows for potential profit or protection against price changes, making them useful tools for managing investment risks or speculating on market movements.
exercise price financial
"These options carry an exercise price of $0.0861 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.
expiration date financial
"These options carry an exercise price of $0.0861 per share and have an expiration date of June 27, 2026"
The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.
Ordinary Shares financial
"He directly holds 3,155,047 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.
