SanDisk stock surges from $25k to $1.13M in one year as datacenter NAND revenue hits $1.47 billion

SanDisk's datacenter segment posted $1.47 billion in Q3 FY26 revenue, up 645% year over year, with non-GAAP gross margin expanding from 22.5% to 78.4% in twelve months. CEO David Goeckeler called it 'a fundamental inflection point'.

A $25,000 investment made in February 2025 when SNDK began trading would have grown to $1.13 million. Multiple Reddit users reported six-figure gains; one investor posted $333k in gains in a single day using options after buying 1,500 shares two weeks prior at $1,000 per share.

Demand for SanDisk's NAND products (memory chips used in data storage) continued to outpace supply, with fabs running at 100% utilization. The company signed five multi-year customer commitments, retired $650 million in debt to reach zero long-term debt, and issued Q4 FY26 guidance of $7.75 billion to $8.25 billion in revenue and $30 to $33 in non-GAAP EPS.
