grant/award acquisition financial

"transaction_action: "grant/award acquisition" for both transactions"

exercise price financial

"conversion_or_exercise_price: "77.1500" for the stock option"

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.

Common Stock financial

"security_title: "Common Stock" and underlying_security_title: "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.
