Insights

Securities Compliance Analyst

TL;DR: Routine Rule 144 notice for a planned insider disposition of a modest block of WDC common stock on NASDAQ.

The notice documents a proposed sale of 14,067 shares worth about $1.05 million via Morgan Stanley Smith Barney LLC on 08/22/2025. The shares derive from an ESPP, restricted stock, and performance awards acquired between 11/2023 and 08/2024. The filing explicitly states no sales in the prior three months. Missing filer CI K/name fields limit identification of the selling person in this excerpt, but the transaction details and acquisition dates are clearly provided, consistent with Rule 144 reporting practices.

Corporate Governance Specialist

TL;DR: Disclosure appears routine and procedural, providing acquisition provenance and planned sale timing without material corporate developments.

The schedule of grant types (ESPP, restricted stock, performance shares) and payment methods (cash or not applicable) helps confirm these are typical compensatory holdings rather than third-party transfers. The filing contains no information about material undisclosed events and includes the required representation regarding material adverse information. However, absent explicit identification of the selling person's relationship beyond the equity types, the filing excerpt does not permit assessment of potential insider timing concerns beyond standard Rule 144 safeguards.
