5 terms

Stock Option (right to buy) financial

"The reported security is a Stock Option (right to buy) with an exercise price."

grant/award acquisition financial

"The transaction action is described as a grant/award acquisition to the director."

exercise price financial

"The options carry an exercise price of $1.6500 per share of common stock."

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

"A footnote states the options vest monthly over 1 year in 12 equal installments."

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.

Common Stock financial

"The underlying security title for the options is listed as Common Stock."

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
