Key Terms

4 terms

Stock Options financial

"security_title: "Stock Options" and underlying security labeled Common Stock"

Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.

grant/award acquisition financial

"transaction_action: "grant/award acquisition" for the CEO option grant"

exercise price financial

"conversion_or_exercise_price set at 1.6200 per share for the 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.

vesting financial

"footnote: "150,000 vest on March 31, 2027 and 12,500 vest monthly""

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.
