weighted-average sales price financial

"Price reported is a weighted-average sales price."

restricted stock units financial

"tax withholding obligations realized upon the vesting of 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.

performance-based restricted stock units financial

"vesting of restricted stock units and performance-based restricted stock units"

Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.

tax withholding obligations financial

"sell only the number of shares ... to cover applicable tax withholding obligations"
