Cents kept per dollar of sales
For every dollar a customer pays Sandisk, some pays for silicon, wafer fabrication, packaging, and shipping. The cents left overbefore paying for R&D, marketing, and overhead — is the company's ~gross margin~. In memory, this number is famously volatile. The market sets the price. The producer mostly takes it. When demand goes up faster than supply can grow, the price spikes.
Wall Street calls this
Gross margin
When this number *triples* in a year, the market is paying *whatever Sandisk asks.* That's pricing power — but it's the *cyclical* kind, not the *structural* kind.
Cents Sandisk keeps per dollar · Q3 FY26
78
¢
A year earlier — 22¢. Two things drove the shift: higher prices on NAND, and a mix shift toward higher-value data-center customers.

78¢ per dollar is extraordinary — but only meaningful in context. If every memory maker doubled their margin in the same year, this is the industry cycle lifting everyone. If Sandisk's margin jumped while peers stayed put, that's company-specific pricing power. The cleanest read is to compare against the closest publicly traded memory peer doing the same thing in the same window.

How the moat got built
1988
Sandisk founded — pioneers compact flash memory cards for cameras and early electronics.
2016
Acquired by Western Digital for $19B. Sandisk becomes WDC's flash-memory arm.
2023
WDC announces plan to spin Sandisk back out as an independent public company.
Feb 2025
Separation completes. Sandisk lists again on Nasdaq as a pure-play NAND business — just as AI demand for storage takes off.
Strong
78¢ per dollar — triple a year ago. The is widest at the top of the cycle.
