The numbers are almost too big to believe. Since being spun off from Western Digital in February 2025, SanDisk has delivered a staggering 3,710% return, making it the single best-performing stock in the S&P 500 year-to-date in 2026, ahead of even Seagate and Intel. But the real question isn’t how far it has come — it’s whether the underlying story justifies continued confidence.

🔄 A New Life as a Pure-Play NAND Company

For nearly a decade, SanDisk was buried inside Western Digital, its NAND flash business competing for capital with Western Digital’s hard drive division. Activist investors, led by Elliott Management, forced a reckoning. On February 24, 2025, SanDisk completed a tax-free spinoff and relisted on Nasdaq under the ticker SNDK. The result: a focused, independent company with no strategic conflict, owning one of the most critical technologies in the AI infrastructure stack.

🤖 Why AI Is SanDisk’s Biggest Tailwind

AI infrastructure is, at its core, a storage problem. Training large language models generates enormous datasets. Inference workloads require low-latency reads at scale. The answer to both is high-capacity, high-performance enterprise SSDs — and NAND flash is the technology inside every one of them. Hyperscalers have made their intentions clear: Google pledged up to $185 billion in AI infrastructure spending in 2026 alone. Meta directly cited rising memory pricing as the primary driver behind its increased capital expenditure guidance. Microsoft attributed roughly $25 billion of its $190 billion 2026 capex to rising component costs. SanDisk, as a pure-play NAND producer in a supply-constrained market, sits directly in the path of all that spending.

📈 The Fundamentals Back Up the Hype

This isn’t just momentum trading. Analysts forecast SanDisk’s sales to soar 42% in fiscal 2026 to approximately $10.45 billion, followed by another 26% growth to $13.15 billion in FY27. Even more striking, annual earnings per share are projected to surge 350% this year to $13.46, with FY27 EPS forecast to nearly double again to around $25.94. Cantor Fitzgerald analyst C.J. Muse has raised his price target to $1,400, maintaining an Overweight rating, citing the potential for long-term supply agreements similar to those in the DRAM market — a move that would add pricing visibility and revenue stability.

⚠️ The Risks Are Real

After a run this dramatic, skepticism is warranted. The price-to-earnings ratio sits well above the company’s five-year median, and the NAND cycle has historically been brutal in both directions. A supply ramp or slowdown in AI capital expenditure could reprice the stock sharply. Institutional investors have been noted taking profits across the broader S&P 500, and some rotation out of SNDK appears to already be underway. The story is powerful, but no stock is immune to gravity.

💡 The Bottom Line

SanDisk’s remarkable run is not a fluke. It reflects genuine structural demand for NAND in the AI era, a clean corporate restructuring that unlocked real value, and a supply environment that has kept pricing favorable. The risks of a high-multiple, cyclical stock are real — but so is the potential for further earnings growth as AI infrastructure spending continues to accelerate. For investors who missed the initial move, the question is whether the fundamentals have grown into the valuation. Based on the numbers, there’s a credible case that they have.
