Sandisk Corporation closed Friday at $606.91, up 5.3%, after bouncing around between $568.30 and $623.28. The stock managed to recoup losses from a volatile run. Western Digital surged 8.7%, Seagate picked up 6.3%, and Micron finished 3.2% higher—gains running through storage and memory stocks.

Investors are still digesting Sandisk’s late-January guidance bombshell. The company put out fiscal third-quarter revenue targets of $4.4 billion to $4.8 billion, and adjusted earnings in the $12 to $14 per share range—both numbers topping consensus. Sandisk also renewed a major supply pact with Kioxia, locking it in through 2034. Morgan Stanley’s team called earnings “above the long-term trend,” and said that could stick around for another year or more, as long as AI appetite holds up. 3
Sandisk, headquartered in Milpitas, California, reported a 61% jump in second-quarter revenue, hitting $3.03 billion. Adjusted earnings landed at $6.20 per share. CEO David Goeckeler said in the statement that “accelerating enterprise SSD deployments” and a stronger product mix drove the gains. 4
