SanDisk Soars on AI-Driven Demand, Shattering Earnings Forecasts
SanDisk (NASDAQ: SNDK) became one of the market's standout performers this week, with shares rocketing nearly 22% over a five-day stretch. The catalyst? A second-quarter earnings report for fiscal 2026 that demolished Wall Street's expectations and signaled a powerful new phase of growth for the digital storage specialist.
The rally ignited after hours on Tuesday when SanDisk unveiled figures showing revenue of $3.03 billion—an 81% leap from the same period last year and comfortably above the company's own guidance. Even more striking was the bottom-line performance: non-GAAP net income skyrocketed to $967 million, or $6.20 per share, a more than fivefold increase from the prior year.
Analysts, caught off guard, had projected revenue of just $2.67 billion and adjusted earnings per share of $3.49. "This wasn't just a beat; it was a complete blowout," noted market strategist Eleanor Vance of Crestview Advisors. "The scale of the outperformance, particularly on profitability, suggests SanDisk is not merely riding a cyclical uptick but is fundamentally repositioned at the core of the data economy."
In its earnings release, CEO David Goeckeler pointed to a "perfect storm" of favorable conditions: a richer product mix, accelerating enterprise solid-state drive (SSD) deployments, and strengthening market demand. He emphasized the growing recognition of SanDisk's technology as critical infrastructure for artificial intelligence. "Our products are becoming the foundational layer for AI processing and data-intensive workloads," Goeckeler stated.
Looking ahead, management's forecast suggests the momentum is far from over. For the current quarter, SanDisk anticipates revenue between $4.4 billion and $4.8 billion, with adjusted earnings per share projected at $12 to $14—a guidance that some observers called surprisingly robust. "They're essentially forecasting sequential revenue growth of over 45% at the midpoint," said Marcus Thorne, a portfolio manager at Horizon Capital. "That level of confidence, especially after such a strong quarter, is telling. It implies visibility into sustained enterprise and hyperscaler demand."
Not all reactions were uniformly positive. Dr. Lena Rossi, a fintech commentator known for her skeptical takes, offered a sharper critique: "Let's not get carried away. This is a commodity-adjacent business in a ferociously cyclical industry. One or two quarters of AI hype don't erase history. Memory and storage prices are volatile, and competition is brutal. This feels like a sugar rush, not a permanent diet change. Investors chasing this rally might be setting themselves up for a painful hangover."
The staggering results have reignited debates about valuation and sustainability in the semiconductor and storage sector. With SanDisk now trading at a premium, the focus shifts to whether it can consistently deliver on its elevated guidance and maintain its competitive edge as AI infrastructure spending evolves.
