Derivative disposition entries 10 transactions Number of derivative-type disposition rows (RSUs and options) reported
restricted stock unit financial
"each reported restricted stock unit ("RSU") was cancelled and converted into the right to receive a cash payment"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
stock option financial
"each reported stock option ("Option") was cancelled and converted into the right to receive a cash payment"
A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
Merger financial
"disposed of in connection with the consummation of the acquisition of the Issuer by Angelini Pharma S.p.A. (the "Merger")"
A merger is when two companies combine into a single business, with ownership and control reorganized so they operate as one entity. For investors it matters because mergers can change the value and risk of holdings—shares may be exchanged, diluted, or rise if the combined company saves costs or gains market power, and the deal often depends on regulatory approval and successful integration like two households joining resources and routines.
