SanDisk Reports Explosive AI-Driven Growth

Western Digital — Sandisk, a computer memory specialist, has seen its shares soar by over 4,000% in the last 12 months, driven by explosive demand for its NAND flash solutions in AI data centers. The company reported a 233% year-over-year revenue increase to $1.47 billion in its fiscal third quarter, with gross margins jumping from 22.7% to 78.4%. Operating income surged from $2 million to $4.2 billion. This growth is fueled by the increasing memory constraints of powerful GPU clusters used for large language models like ChatGPT. Analysts project significant spending on AI data centers, ensuring continued demand for Western Digital — Sandisk's products. Despite its rapid growth, Western Digital — Sandisk's forward P/E ratio remains relatively low, reflecting investor caution about the memory industry's cyclical nature and potential AI bubble risks. However, a multiyear chip shortage is anticipated, with Western Digital — Sandisk's 2026 production already sold out.
