restricted stock units ("RSUs") financial
"On August 6, 2026, the Reporting Person received a grant of 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.
PRSUs financial
"the Reporting Person was also 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.
performance-based and service-based vesting conditions financial
"RSUs granted that were subject to only service-based vesting conditions, the Reporting Person was also granted RSUs with both performance-based and service-based vesting conditions"
free cash flow financial
"if KLA's free cash flow relative to its peers was at the 75th percentile or greater"
Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.
fair market value financial
"The fair market value of KLA common stock used for purposes of calculating the number of shares to be withheld"
The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.
