Key Terms

4 terms

restricted stock units financial

"the Reporting Person was granted restricted stock units ("RSUs") of shares"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

vested financial

"On August 3, 2026, twenty-five percent (25%) of the RSUs vested"

fair market value financial

"The fair market value of KLA common stock used for purposes of calculating"

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.

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.
