Tregillis, Chief Legal Officer and Corporate Secretary of Western Digital Corp ($WDC), sold 807 shares of common stock at a price of $380.00 per share, totaling $306,660.00.

Transaction Details
- Open Market Sale: 807 shares sold on October 21, 2026, at $380.00 per share.
- Tax Withholding: 1,309.713 shares surrendered on October 20, 2026, at $364.32 per share to satisfy tax obligations upon vesting.

Market and Trading Context
The open-market sale represents less than 1% of the insider's total equity holdings in the company. Because the disposal was executed under an existing Rule 10b5-1 plan and reflects a modest fraction of her total position, this transaction is viewed as routine personal financial planning and carries low overall trading significance.
