Cole Martin I 4

What Happened

• Cole Martin, a director of Western Digital Corp. (WDC), was credited with 0.404 dividend-equivalent rights related to previously awarded restricted stock units (RSUs) on 2026-06-17. The reported amount is 0.404 shares at $0.00 (derivative award), i.e., no cash purchase or sale occurred.

Key Details

• Transaction date: 2026-06-17; filing date: 2026-06-22 (appears to be filed after the standard 2-business-day Form 4 window).
• Transaction type/code: Award/Acquisition (A); amount: 0.404 shares; price: $0.00.
• Shares owned after transaction: Not specified in this filing.
• Footnote: The 0.404 represents dividend equivalent rights that accrue on the RSUs and vest proportionately with those RSUs. Each right is a contingent claim to one common share or its cash value.

Context

• This is a routine equity compensation accrual rather than a market purchase or sale. Dividend-equivalent rights simply track dividends on RSUs and convert to shares or cash when the underlying RSUs vest, and do not necessarily indicate a change in trading sentiment. The late filing may be an administrative matter but is noted for disclosure completeness.
