Sandisk Corp. insider Bernard Shek reported a change in beneficial ownership of the company’s common stock tied to sales made on July 1, 2026. The Form 4 was filed on July 2, 2026, covering transactions in Sandisk common stock under ticker SNDK. The filing states that the sales were executed pursuant to a Rule 10b5-1 trading plan adopted by Shek on March 4, 2026. Such plans allow insiders to schedule trades in advance under predetermined conditions, which can help demonstrate that sales were not made on the basis of material nonpublic information available at the time of execution. The provided filing text does not include the number of shares sold, sale prices, transaction codes, or Shek’s ownership following the transactions. It also does not provide any vesting, option-exercise, or derivative-security details. The key reported action is therefore an insider sale of Sandisk common stock on July 1, 2026, carried out under a prearranged 10b5-1 plan.
