Insights

Equity compensation and insider-trading analyst

Routine open-market sale; executive retains a substantial share position.

Chief of Global Operations Gubbi Vidyadhara K sold 8,518 shares of Western Digital common stock at an average price of $255.325 per share. The transaction is coded as an open-market sale, indicating an active decision to dispose of shares.

Following the sale, he still directly owns 99,276 shares, which suggests the transaction affects only a relatively small portion of his overall stake. There are no derivative holdings disclosed in this filing, so the visible equity exposure is entirely through common stock as of the reported date.

The filing does not reference a Rule 10b5-1 trading plan, so the timing appears discretionary based on the available data. Future Form 4 filings may provide additional context on whether this sale is part of a broader pattern or a one-time liquidity event.
