restricted stock units (RSUs) financial

"Represents a sale to cover tax obligations on the release of restricted stock units."

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

performance restricted stock units (PSUs) financial

"Includes 1,435,162 shares represented by RSUs and performance restricted stock units."

weighted average price financial

"The price reported is a weighted average price. These shares were sold in multiple transactions."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

tax obligations financial

"Represents a sale to cover tax obligations on the release of restricted stock units."

performance milestones financial

"The PSUs vest upon achievement of certain performance milestones, subject to continued service."
