[SanDisk Performance Guidance Disappoints, Shares Drop 8% After Hours] BlockBeats News, August 6 — SanDisk (SNDK.O) reported strong Q4 performance for fiscal year 2026, with both revenue and profit exceeding market consensus. Revenue surged 372% year-over-year and grew 51% quarter-over-quarter. The company's board of directors approved a $14 billion stock repurchase plan. Options expiring the week of August 7 show the $1,370 strike price holding the highest open interest in both call and put options, suggesting that intense options trading following the earnings report may be partly responsible for the stock's weak performance. Another possible reason for the after-hours decline could be the next quarter's revenue outlook ($10.3 billion–$10.8 billion), which fell short of expectations. SanDisk management stated, 'Revenue exceeded expectations thanks to our shift toward high-value customers (data center business grew 437%) and increased pricing.' According to BIT (bit.com) market data, SanDisk's U.S. shares dropped as much as 8% after hours and are currently down 5.57%.
