"security_title": "Stock Option (Right to Buy)""

exercise price financial

"conversion_or_exercise_price": "5.9500""

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

"which will vest in full on the earlier of the one-year anniversary"

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.

annual meeting of stockholders financial

"or immediately prior to the Issuer's next annual meeting of stockholders"
