WESTERN DIGITAL CORP 4

CEO Irving Tan had RSUs and related dividend equivalents vest in Western Digital common stock and shares withheld for taxes on May 20–21, 2026, resulting in minor net changes to his large direct holdings.

On May 20 and 21, 2026, Western Digital Corporation CEO Irving Tan had restricted stock units and related dividend equivalent rights vest, resulting in the acquisition of small incremental amounts of common stock through the conversion of dividend equivalent rights (approximately 12.56 and 23.68 shares, respectively, on a one‑for‑one basis into common stock). In connection with these vestings, the company withheld 145 shares on May 20 at an implied price of about $459.62 per share and 587 shares on May 21 at an implied price of about $486.46 per share to satisfy tax obligations, which are coded as disposition transactions but are routine, non‑discretionary withholdings under Rule 16b‑3(e). After these transactions, Tan held roughly 598,017–598,040 shares of Western Digital common stock directly, with an estimated multi‑hundred‑million‑dollar position based on the high per‑share values implied by the tax‑withholding prices.
