Since spinning off from its former parent in February 2025, Sandisk shares have climbed more than 1,030% over the past 11 months, making it the best-performing stock in the S&P 500 for 2025. This remarkable rally reflects investor enthusiasm for the company’s pure-play focus on flash storage, as well as its ability to capitalize on the surge in demand for high-speed devices. Sandisk achieved its first cash-flow target six months ahead of schedule and has maintained a gross margin above 29%, underscoring strong pricing power driven by a tight supply environment.

Sales to data-center operators currently account for roughly 12% of Sandisk’s total revenue, yet this segment is poised to be the primary growth driver over the next several years. Hyperscale cloud providers are projected to invest hundreds of billions of dollars in AI infrastructure build-outs, and flash storage is a critical component of model training and checkpointing workflows. Industrywide supply constraints have forced standard memory output down by an estimated 20% in the past year, allowing Sandisk to raise prices by double digits without dampening order volumes.

Sandisk trades at approximately 31 times projected earnings for the coming year, a premium to long-established tech giants but a discount to some AI hardware peers. Wall Street analysts are divided: one major bank warns of a potential 53% downside based on a target near $235, arguing that today’s chip shortage may reverse, while others highlight Sandisk’s vertical integration and forecast triple-digit EPS growth, from about $2.99 in 2025 to $13.46 in 2026. Given the stock’s rapid ascent, many investors favor a dollar-cost-averaging approach rather than a lump-sum allocation to manage the risk of a sharp correction.
