service-based Restricted Stock Units financial
"award of service-based Restricted Stock Units"
Service-based restricted stock units are promises by a company to give employees shares of stock only after they remain employed for a specified period; the stock is delivered gradually or all at once once the service condition is met. Investors care because these awards affect future share supply and company costs, align employee interests with long-term performance, and can influence dilution and earnings reports when the promised shares are recorded or issued.
Performance RSUs financial
"based on performance targets ("Performance RSUs")"
Performance RSUs are promises to deliver company shares to executives or employees only if the business meets preset goals such as revenue, profit, stock price, or operational targets. They matter to investors because they align management pay with measurable company results and can affect the number of shares outstanding and future earnings per share once the shares are issued. Think of them as a bonus paid in stock that only arrives if the team hits the agreed milestones.
vesting period financial
"4,265 Performance RSUs over the vesting period"
A vesting period is the set amount of time someone must wait before they fully own granted shares, stock options, or other equity tied to their work or an agreement; ownership increases gradually or in steps during that time. Investors care because vesting determines when insiders or employees can sell shares, which affects future supply of stock, company incentives and executive retention—think of it like unlocking ownership over installments rather than receiving it all at once.
