restricted stock units ("RSUs") financial

"in addition to the restricted stock units ("RSUs") granted that were subject"

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

"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

"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"

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.

tax withholding financial

"shares of KLA common stock were automatically withheld at vesting to cover required tax withholding"

Tax withholding is the practice of taking a portion of a payment—such as wages, dividends, or sale proceeds—before it reaches the recipient and sending that portion to the tax authority as an advance on the recipient’s eventual tax bill. For investors it matters because withholding reduces immediate cash received and affects after‑tax returns, estimated tax payments, and whether you may owe more or receive a refund when taxes are finally calculated, like having a small automatic savings set aside for your tax bill.
