SanDisk's performance guidelines were poor and fell 8% after the market

Comparing news, SanDisk (SNDK.O) had strong Q4 performance in FY2026, and both revenue and profit exceeded market consensus. Revenue surged 372% year over year and 51% month over month. Options due in the week of August 7 showed that the exercise price of $1,370 held the highest volume of open positions among both bullish and bearish options. Intense options trading after the earnings report was announced may be at least part of the reason for the weak stock price performance. The revenue forecast for the next quarter (US$10.3 billion to US$10.8 billion) falls short of expectations and may also be one of the reasons for the lower share price after the market. SanDisk management said, “Revenue exceeded expectations due to our shift to a portfolio of high-value customers (437% increase in data center business) and price increases.” SanDisk shares fell 8% after the market.
