stock option financial
"Ms. Chew was granted a total of 62,500 stock options exercisable for an aggregate"
A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
exercise price financial
"at a price per option of $0.80. In aggregate, Ms. Chew's stock options"
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.
Class A Ordinary Shares financial
"exercisable for approximately 2.435 Class A Ordinary Shares of Horizon Quantum Holdings Ltd."
Class A ordinary shares are a type of ownership stake in a company that typically grants voting rights to shareholders, allowing them to have a say in important company decisions. They often come with priority in receiving dividends or profits, making them attractive to investors seeking influence and potential income. These shares help distinguish different levels of ownership and rights within a company's stock structure.
vesting financial
"The remaining stock options are subject to Ms. Chew's continued employment and vest quarterly"
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
fully vested and exercisable financial
"As of August 4, 2026, 46,875 stock options are fully vested and exercisable"
