SanDisk (SNDK) stock is the top performing stock of the S&P 500 ($SPX). Shares are up more than 147% year-to-date (YTD) and are up more than 1,000% in just six months. The development of artificial intelligence (AI) data centers has boosted demand for memory products used in AI infrastructure, thus supporting SNDK stock.
The rapid development of AI-centric data centers has significantly increased demand for NAND flash memory, a core component of SanDisk’s product portfolio. The company provides high-performance flash storage solutions designed to support AI workloads in hyperscale data centers, edge computing environments, and consumer applications. As enterprises scale AI capabilities, the need for reliable, high-capacity, and energy-efficient storage continues to grow, SanDisk is positioned to take advantage of these emerging industry trends.
In addition to favorable demand dynamics, SanDisk is benefiting from supply-side constraints in the global memory market. With limited availability, producers have been able to set higher prices, supporting margin expansion and improved profitability.
Recent financial results show that high demand and prices have enabled SanDisk to deliver record revenues and earnings. In the second quarter of fiscal 2026, SanDisk reported a 61% year-over-year (YoY) increase in net income. Growth was primarily driven by a 36% increase in average selling prices per gigabyte and a 22% increase in exabytes sold, reflecting strong demand for the company’s data storage products. The combination of higher prices and increased shipping volumes has translated into a significant revenue boost. It posted adjusted earnings of $6.20 per share in Q2, up 408% YoY.
However, after such a rapid rise, should investors cash out or hold on to SNDK stock for further gains?

While SanDisk has delivered significant growth, the pace of its business is unlikely to slow down anytime soon. A major catalyst is the planned increase in capital spending by hyperscalers, which are investing heavily in AI infrastructure.
As hyperscale continues to expand AI-centric data center capacity, the demand for high-performance storage is growing in tandem. AI workloads, especially inference at scale, require significantly higher NAND density everywhere. This dynamic directly benefits SanDisk’s enterprise solid-state drive (SSD) portfolio, where demands are accelerating across the broader data center ecosystem.
For SanDisk, this change is not limited to a few customers. Adoption is expanding across enterprise data centers, infrastructure infrastructure operators, OEMs, and system integrators building AI-ready systems. This diversification strengthens the revenue outlook and reduces concentration risk. Management expects the data center segment to deliver significant growth, reflecting structural demand trends.
At the edge, the imbalance between supply and demand is even more pronounced. The era of deployment in computers and mobile devices, combined with AI-enabled features that require high storage density, is pushing device configurations toward richer, higher-capacity architectures. Demand significantly outpaced supply in Q2, allowing SanDisk to take advantage of volume expansion and favorable pricing dynamics. In consumer markets, the mix shifted to premium products and higher value configurations, supporting margin expansion along with revenue growth.
Going forward, SanDisk projects customer demand to outstrip available supply through at least 2026. Such continued volatility will create favorable pricing conditions and operating leverage for SunDisk, delivering significant revenue and earnings growth in fiscal 2026 and 2027.
For the upcoming third quarter, the company is guiding revenue between $4.4 billion and $4.8 billion, implying sequential growth of 45% to 58%. This represents a faster pace than previous quarters. The profit expectation is very high. Adjusted gross margin is estimated to be in the range of 65% to 67%, significantly higher than last quarter and year-ago levels. Adjusted EPS is estimated between $12 and $14, with the midpoint suggesting earnings could double sequentially.
Profit expectations for the third quarter support a bullish outlook for SNDK stock. SanDisk is forecasting an adjusted gross margin of 65% to 67%, a significant increase from Q2 levels and better than the margin recorded a year ago. Adjusted EPS is estimated between $12 and $14, with the midpoint implying that earnings could double sequentially.
A strong demand environment, a broad customer base, continued supply tightness, and an accelerating margin profile indicate that SanDisk is well positioned to deliver significant gains in the coming years.
From a value perspective, SNDK stock doesn’t appear to be expanding despite its recent rally. SNDK trades at a forward price-to-earnings ratio of 27.7, a number that seems reasonable given the expected earnings growth. Analysts anticipate an extraordinary increase in EPS of 1,189.9% in FY2026, followed by another year of strong growth in FY2027. Strong profitability helps justify current value and leaves room for expansion.
That said, not all analysts are bullish on SNDK stock after the strong rally. The consensus rating is “Moderate Buy”, reflecting some caution around the cyclical nature of the memory market and macro uncertainty.
However, as NAND demand remains strong and prices continue to accelerate, SanDisk is well positioned to maintain its growth strategy, suggesting further upside for SNDK stock.
