STREETER STEPHANIE A 4

What Happened

• Stephanie A. Streeter, a director of Western Digital Corp. (WDC), was granted 0.65 shares as a derivative award on 2026-03-18. The award was recorded at $0.00 per share (total cash paid $0). The filing classifies this as an award/acquisition (code A) of derivative securities tied to previously issued RSUs.

Key Details

• Transaction date: 2026-03-18; Filing date (Form 4): 2026-03-19.
• Price: $0.00 per share; Shares acquired: 0.65 (derivative security).
• Shares owned after transaction: not specified in the filing.
• Footnote: The 0.65 represents dividend equivalent rights (DERs) that accrued on previously awarded RSUs and vest proportionately with those RSUs; each DER is a contingent right to receive one share or the cash value thereof (see footnote F1).
• No 10b5-1 plan, tax-withholding, or late-filing indication is reported.

Context

• These are dividend-equivalent rights tied to RSUs, not an open-market purchase or sale. DERs typically convert to shares or cash when the related RSUs vest, so this transaction reflects compensation accounting rather than an expressed buy/sell market sentiment.
