employee stock purchase plan financial

"Purchased under the registrant's employee stock purchase plan."

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

restricted stock units ("RSUs") financial

"includes 217,169.680 shares issuable upon vesting of restricted stock units ("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.

performance-based and service-based vesting conditions financial

"RSUs with both performance-based and service-based vesting conditions ("PRSUs") divided into three tranches."

PRSUs financial

"performance-based and service-based vesting conditions ("PRSUs") divided into three tranches."

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.

tax withholding financial

"shares of KLA common stock were automatically withheld to cover required tax withholding on the 61,651.800 shares"

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.
