5 terms

restricted stock units financial

"Represents grant of restricted stock units (the "RSU Award") payable solely in common stock of the Issuer."

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.

Retainer RSU Award financial

"Represents grant of restricted stock units (the "Retainer RSU Award") payable solely in common stock of the Issuer."

Non-Employee Director Compensation Policy financial

"retainer cash fees provided for under the Issuer's Non-Employee Director Compensation Policy."

Director Stock Option financial

"Director Stock Option (right to buy)"

exercise price financial

"conversion_or_exercise_price": "2.5200""

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.
