restricted stock units financial
"which included 689,467 shares of Common Stock and 319,213 restricted stock units"
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.
stock option financial
"In connection with consummation of the Merger, each reported stock option ("Option") was cancelled"
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 consummation of the acquisition of the Issuer by BioMarin Pharmaceutical Inc. (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.
exercise price financial
"equal to (a) the excess of (i) $14.50 per share over (ii) the exercise price payable per share"
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.
cash payment financial
"was cancelled and converted into the right to receive a cash payment equal to"
