Restricted Stock Units financial
"Each reported restricted stock unit represents a contingent right to receive one share"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Disposition to issuer financial
"Transaction code D is described as a disposition to issuer of the reported securities"
consummation of the acquisition regulatory
"Securities were disposed of in connection with the consummation of the acquisition by Angelini Pharma"
Angelini Pharma S.p.A. financial
"The reported securities were disposed of in connection with the acquisition by Angelini Pharma S.p.A."
exercise price financial
"Cash payment equals the excess of $31.50 per share over the per-share exercise price of each 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.
