Key Terms

restricted stock units ("RSUs"), PRSUs, Rule 10b5-1 trading plan, performance-based and service-based vesting conditions

4 terms

restricted stock units ("RSUs") financial

"granted restricted stock units ("RSUs") of shares of KLA common stock"

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.

PRSUs financial

"granted RSUs with both performance-based and service-based vesting conditions ("PRSUs")"

A PRSU is a type of employee equity award that turns into actual company shares only if preset performance goals are met over a specified time. Think of it like a prize that only pays out when a team hits agreed targets; investors watch PRSUs because they tie management pay to results, can increase the number of shares outstanding when paid, and therefore affect shareholder value and incentives.

Rule 10b5-1 trading plan financial

"sale was effected pursuant to the terms of a Rule 10b5-1 trading plan"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

performance-based and service-based vesting conditions financial

"RSUs with both performance-based and service-based vesting conditions ("PRSUs")"
