Evaluating Sandisk as a Potential Millionaire-Maker Investment

Key Points

• Sandisk’s NAND flash memory products are in high demand for data centers, leading to scarcity.

• Sales are skyrocketing as the company deals with high demand and low supply.

• Sandisk stock has become expensive.

Sandisk (NASDAQ: SNDK) reported a staggering 250% revenue growth and a 4,600% stock gain since its spin-off from Western Digital last year. A $25,000 investment at the time is now valued at nearly $1.2 million.

The surging demand for Sandisk’s NAND flash memory products is largely driven by increased data storage needs in data centers, especially in AI applications. The gross margin rose from 22.5% to 78.4% in Q3 2026, with operating income increasing by 386%. This comes amid limited competition, primarily from Micron Technology, resulting in higher prices due to supply constraints.

Despite the current revenue boom, concerns linger over potential cyclical downturns in the memory market. Sandisk has signed multiyear new business model agreements to stabilize its revenue stream, while its stock currently trades at 59 times trailing-12-month sales, raising questions about future investment risks.
