Analysis · SNDK · Technology
CEO David Goeckeler has filed a Form 144 to sell 33,838 shares worth approximately $55.3 million. The sale is executed under a 10b5-1 trading plan adopted on May 29, 2026, which means it was pre-scheduled and not a reaction to current market conditions. The shares come from restricted stock units that vested in May and performance stock units that vested in August. While the dollar amount is substantial, the pre-planned nature of the sale reduces the informational value about the CEO's current view of the company. This follows a pattern of insider selling at Sandisk, with $11.96 million in net insider sales over the past 90 days.
