How to read the table
Only open-market purchases and sales are trades the insider chose to make at the market price, and they are the ones counted in the summary above. Grants, option exercises and shares withheld for tax come from pay plans. A sale marked as a 10b5-1 plan was scheduled in advance under a written plan.
Where each row comes from
From the Form 4 that each executive, director or large shareholder must file with the SEC within two business days of a transaction, read up to 10 November 2026. Each row links to its filing on EDGAR. Only transactions in shares are listed, not derivatives, and amended filings are left out. The accounts of the company are on the KLA page; the method, in data sources.
