"Non-Qualified Stock Option (right to buy)"

Restricted Stock Units financial

"Each 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.

tranche financial

"the third and final tranche of his July 2024 RSU grant award"

A tranche is one slice of a larger financing or investment that is released, sold, or paid out in separate parts rather than all at once. Investors care because each slice can carry different risk, return and timing—like buying pieces of a cake where some slices are richer or come later—so the specific tranche you hold affects when you get paid and how much you might gain or lose.

ratably financial
