Tan Irving, chief executive officer of Western Digital (WDC), has filed 86 Form 4 transactions across two companies. The pattern is one-sided. His total open-market sales reach $25.6 million, while his open-market purchases total zero. The only other money moving in his direction is $4,843.64 in acquired value, which is compensation, not a buy.
The recent activity is concentrated in WDC and heavily skewed toward selling. On August 11, 2026, Irving executed six open-market sales in a single day, totaling roughly $7.8 million. The individual transactions ranged from $437,351.13 to $2,876,926.83. That was the last open-market selling event. Since then, his filings have been mechanical: option exercises (code M) with zero value, shares withheld to cover tax (code F), a grant (code A) on September 17, and a gift (code G) on September 1.
The F-code transactions are the largest dollar figures in the recent window. On August 26, 2026, $1,553,868.32 was withheld for taxes, and on September 20, $481,539.21 was withheld. These are automatic, not discretionary. The August 11 sales are the only recent trades that represent a deliberate decision to reduce his position, and they are substantial. Irving has not bought a single share on the open market in any of the 86 filings. The direction is unambiguous: he sells, and he does not buy.
