MASSENGILL MATTHEW E 4

What Happened

• Matthew E. Massengill, a director of Western Digital Corp. (WDC), received an award of 6.109 derivative shares on June 17, 2026. The filing shows the acquisition price as $0.00, i.e., no cash was paid for these units. This was an award/vesting-type transaction (not an open-market purchase or sale).

Key Details

• Transaction date: 2026-06-17; Filing date: 2026-06-22 (as reported).
• Transaction type/code: A — Grant/Award (derivative).
• Shares involved: 6.109 shares acquired at $0.00; reported total value $0.
• Shares owned after transaction: not provided in the supplied filing summary.
• Footnote: Dividend-equivalent rights accrued on previously awarded restricted stock units (RSUs) and vest proportionately with those RSUs; each represents a contingent right to one share or the cash value thereof (per filing footnote).
• No indication in the provided data that this was a sale, a 10b5-1 plan trade, or a tax-withholding event.

Context

• This transaction reflects compensation-related award mechanics rather than a market purchase or sale. Dividend-equivalent units commonly accrue on RSUs and convert to shares (or cash) when the underlying RSUs vest; they do not by themselves signal a buy or sell intent.
• For retail investors, awards and dividend-equivalent accruals are routine director/executive compensation events and should be interpreted differently than outright purchases (which can be a stronger bullish signal) or sales (which may be liquidity-related).
