Key Terms

Stock Option (Right to Buy), exercise price, vesting, beneficially owned

4 terms

Stock Option (Right to Buy) financial

"security titled "Stock Option (Right to Buy)" was granted"

exercise price financial

"conversion or exercise price of $0.9549 per share applies"

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

"vests over a three-year period with one-third vesting on the first 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.

beneficially owned financial

"total derivative securities beneficially owned following the grant"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
