[Form 4] Western Digital Corp. Insider Trading Activity

Rhea-AI Filing Summary

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.

Insights

Financial Analyst

TL;DR: Routine 10.76 DER accrual; negligible financial impact.

The filing records a small, automatic accrual of dividend-equivalent rights tied to existing RSUs. At roughly 11 shares, the economic value is immaterial relative to Western Digital’s market capitalization and daily trading volume. No cash changed hands and no voting power meaningfully shifted. Investors should treat this as standard housekeeping under the company’s equity compensation plan.

Corporate Governance Expert

TL;DR: Compliance update; no governance signal detected.

Streeter’s Form 4 complies with Section 16(a) reporting requirements. Because the rights vest proportionally with prior RSUs and involve no discretionary trade, the event offers no insight into insider sentiment or upcoming strategic moves. Governance risk unchanged.
