BlockBeats News, August 6th, SanDisk (SNDK.O) reported a strong performance for Q4 of the 2026 fiscal year, with revenue and profit both beating market consensus. The revenue surged by 372% year-over-year and grew by 51% quarter-over-quarter.

Options expiring in the week of August 7th showed that the $1370 strike price held the highest open interest in both call and put options, suggesting that the intense options trading after the financial report may have been at least partially responsible for the weak stock performance. The lower-than-expected revenue outlook for the next quarter ($10.3 billion-$10.8 billion) may also be one of the reasons for the stock price decline after hours.

The SanDisk management team stated, "The better-than-expected revenue was driven by our shift towards a high-value customer mix (437% growth in data center business) and price increases."

According to BIT (bit.com) market data, SanDisk's US stock price briefly fell by 8% after hours, and is currently down by 5.57%.
