KIDDOO BRUCE E 4

What Happened

• Bruce E. Kiddoo, a director of Western Digital Corp. (WDC), was issued an award on 2026-03-18 consisting of 0.65 shares (reported as acquired at $0.00). The filing classifies this as a derivative acquisition tied to previously granted restricted stock units (RSUs), so no cash was paid for these 0.65 shares.

Key Details

• Transaction date: 2026-03-18; Form 4 filed: 2026-03-19.
• Transaction type/code: Grant/Award (A); 0.65 shares acquired at $0.00 (derivative).
• Shares owned after transaction: Not specified in the filing provided.
• Footnote: Dividend-equivalent rights accrued on previously awarded RSUs and vest proportionately with those RSUs; each right represents a contingent claim to one share of common stock or its cash value.
• Timeliness: Filing appears timely (next-business-day filing; no late filing indicated).

Context

• This was an award of dividend-equivalent rights on RSUs (a form of compensation), not an open-market purchase or sale. Such small, routine awards are common for directors and reflect compensation mechanics rather than a direct buy/sell signal about company prospects.
