restricted stock units ("RSUs") financial

"in connection with the net settlement of restricted stock units ("RSUs")"

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

net settlement financial

"in connection with the net settlement of restricted stock units ("RSUs")"

performance-based RSUs financial

"Certain of these shares are represented by time-based and performance-based RSUs"

Performance-based restricted stock units (RSUs) are promises to deliver company shares to employees only if the business meets specific goals, such as revenue, profit, stock-price targets, or strategic milestones. For investors, they matter because they change future share supply and align management incentives with company results—like a salesperson whose bonus only pays out when sales targets are hit—so they can affect earnings, dilution, and confidence in leadership.
