SanDisk, a memory company, is set to report its fiscal third-quarter earnings on April 30. The company, known for its memory cards, flash drives, and SSDs, reported a 31% increase in revenue from the previous quarter and 61% from the year-earlier period. Despite this, Wall Street is looking for signs that SanDisk's recent surge has more room to run. The firm's guidance, which included a non-GAAP gross margin of 65% to 67%, well above the 51.1% non-gaAP gross profit it reported in the second quarter, made it harder for investors to ignore. The next test will be whether SanDisk can prove its NAND recovery has become strong enough to support a higher level of earnings power. SanDisk’s performance in the data center side of the business is becoming more important, particularly as AI demand spreads beyond semiconductor companies.
