Western Digital filings document material events for an operating storage company whose common stock trades on the Nasdaq Global Select Market under WDC. Recent 8-K disclosures record quarterly operating and financial results, dividend and capital-structure matters, shareholder voting and governance items, and material agreements.
The filing record also describes security-structure changes, including the mandatory conversion of Series A Convertible Perpetual Preferred Stock into common stock, the Certificate of Elimination for that preferred series, and redemptions or discharge of senior-note obligations. These documents frame WD's public-company reporting around results, debt and equity instruments, governance, and corporate actions following the completed Flash business separation.

Zamiska, automatically acquired 66.941 dividend-equivalent rights on 18 June 2025.

The acquisition was reported under transaction code “A” at a price of $0.00, indicating no cash outlay by the insider. After the transaction, Zamiska’s beneficial ownership in this derivative class stands at 66.941 units. No common-stock sales or other dispositions were reported, and the filing contains no additional equity transactions.
Western Digital Corp. (WDC) – Form 4 insider transaction
Director Stephanie A. Streeter reported one transaction dated 06/18/2025. She acquired 10.7603 dividend-equivalent rights (DERs) that are linked to previously granted restricted stock units (RSUs). Each DER represents a contingent right to receive either one share of Western Digital common stock or its cash value when the underlying RSUs vest. The acquisition price was $0.00, and all DERs are held directly. Following the transaction Streeter beneficially owns 10.7603 DERs; no common shares were bought or sold in the open market.
The filing, signed on 06/23/2025 by attorney-in-fact Sandra Garcia, reflects routine accrual of dividend equivalents rather than an active share purchase or sale. No other derivative or non-derivative transactions were reported.
Western Digital Corporation (WDC) filed a Form 4 indicating that director Roxanne M. Oulman acquired 6.8728 dividend-equivalent rights on 18 June 2025. These rights stem from previously granted restricted stock units (RSUs) and will vest proportionally with the underlying RSUs. Each dividend-equivalent right represents a contingent claim to one share of common stock—or its cash value—once vesting occurs. The filing shows no purchase or sale of common shares; the transaction price is recorded at $0.00, confirming it is a routine, non-cash adjustment tied to dividend accruals. After the transaction, Oulman beneficially owns 6.8728 derivative securities directly, and her status remains that of an independent director rather than an officer or 10% holder.
Western Digital Corp. (WDC) – Form 4 filing for Director Bruce E. Kiddoo
On 06/18/2025, Director Bruce E. Kiddoo acquired 6.8728 dividend equivalent rights that relate to previously granted restricted stock units (RSUs). The rights were credited at $0.00 cost and will vest proportionately with the underlying RSUs, giving the holder a contingent right to receive either one share of common stock or cash per right upon vesting. Following the transaction, Kiddoo directly holds exactly 6.8728 derivative securities of this type. No common shares were bought or sold and no cash changed hands; the filing merely records routine accrual of dividend equivalents under the company’s equity-compensation plan.
No other derivative or non-derivative transactions, sales, or additional grants were reported, and there is no indication of a 10b5-1 trading plan. The action is administrative in nature and does not meaningfully alter insider ownership or signal a strategic view on WDC’s share value.
