Tregillis Cynthia L, Chief Legal Officer and Corporate Secretary, has demonstrated a consistent pattern of selling activity in Western Digital Corporation (WDC) shares, with no recorded purchases across 56 transactions. Recent SEC Form 4 filings show seven sales between January and March 2026, totaling approximately $3.2 million in aggregate value. The largest single disposal occurred on March 4, 2026, when Tregillis sold shares worth $2.3 million, followed by a $1.83 million transaction on February 6. Smaller but notable sales included $200,396 on March 4 and $316,642 on February 21, with multiple sub-$100,000 dispositions throughout the period.
The transactions appear structured, with sales frequently preceded by "M" (merger/acquisition) or "F" (tax-related) coded events that triggered no monetary value changes but often preceded monetization. For example, a February 25 filing shows a $224,031 sale following such an event. Tregillis's activity is exclusively concentrated in WDC, with no holdings or trades disclosed in other issuers. The absence of buy transactions and the repeated monetization of equity—particularly the seven-figure sales—suggest an ongoing reduction in exposure to Western Digital stock. The timing of sales does not indicate clustering around earnings releases or other predictable corporate events.
