KLA Corp President and CEO Richard P. Wallace reported routine equity compensation-related transactions in KLA common stock.

Rhea-AI Filing Summary

KLA Corp President and CEO Richard P. Wallace reported routine equity compensation-related transactions in KLA common stock. On June 30, 2026, 92,477.700 performance-based restricted stock units vested following the Board’s prior determination that the applicable performance conditions for the second tranche were satisfied.

To cover required tax withholding on the vested shares, 45,850.444 shares were automatically withheld at a price of $278.39 per share, a non-market, tax-withholding disposition. Separately, he acquired 196.1599 shares at $108.33 per share under the employee stock purchase plan, reflecting 85% of the closing price on January 2, 2026, the first day of that offering period.

After these transactions, Wallace’s reported holdings include 668,175.7959 shares of KLA common stock, which at different points include 575,111.680 and later 482,633.980 shares issuable upon vesting of RSUs. The filing shows compensation-driven and tax-related adjustments rather than open-market buying or selling.

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

"The number of shares of KLA common stock includes 575,111.680 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 ("PRSUs") financial

"the reporting person was granted RSUs with both performance-based and service-based vesting conditions ("PRSUs") divided into three tranches."

offering period financial

"the first day of the offering period under the employee stock purchase plan."

tax withholding financial

"shares of KLA common stock were automatically withheld to cover required tax withholding on the 92,477.700 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.
