SanDisk Put Margin Targets on Its AI Memory Story and the Stock Took Off

SanDisk gave investors a number for the part of the AI memory story that usually stays qualitative, and the stock rose roughly 14%.

The company guided to mid-to-high-teens annual revenue growth from fiscal 2028 through 2030, and attached margin targets to it: roughly 80% gross margins and roughly 75% operating margins.

The gap is the argument

An 80% gross margin is a strong number in memory. A 75% operating margin alongside it is the more aggressive of the two, because it implies operating expenses consume about five points of revenue at scale.

That is a statement about fixed-cost leverage: it says the business gets there by growing into a cost base rather than by spending proportionally to grow. Memory has historically been the opposite kind of business, which is why the market treated this as new information rather than a restatement.

What to hold lightly

These are targets for fiscal 2028 through 2030, which is far enough out that no part of it is yet a result. Guidance that distant is a description of the model the company believes it is building, and the stock moved on the model, not on a quarter.
