Sandisk Corporation (NASDAQ:SNDK) is benefiting from data-center demand, but valuing the entire company as though all its sales share those economics would miss most of the business. Its fiscal fourth quarter produced $8.97 billion of revenue, of which $2.98 billion came from data centers. The segment’s share was about 33%, leaving roughly two-thirds elsewhere.
That distinction matters at September 30’s $1,739.89 share price and approximately $254.75 billion market capitalization. Sandisk earned $11.43 billion in fiscal 2026, making the stock roughly 22 times that year’s net income. Investors are paying for profits that accelerated sharply within the year. The durability of edge-device demand and industry pricing therefore matters alongside AI storage.
The storage boom creates a stock choice as well as a demand story: Micron or Sandisk—which AI memory stock offers the better value? asks which memory franchise offers the better return for its price. The answer depends partly on how much profitability persists outside data centers.
A fast-growing segment can still be a minority
Data-center revenue rose from $213 million in the year-earlier quarter to $2.98 billion. Its full-year contribution was $5.15 billion out of total sales of $20.25 billion, or about 25%. The quarterly mix is more exposed to data centers than the annual mix, supporting the view that the company’s economic profile is changing.
Yet fourth-quarter edge revenue was still $5.43 billion and consumer revenue $556 million. Large gains in data-center sales do not remove the pricing sensitivity of those businesses. Nor does segment revenue reveal segment profitability: without a corresponding operating-profit breakdown, investors cannot assign all the consolidated margin improvement to enterprise demand.
The bull case is that higher-capacity, higher-performance storage requirements expand alongside AI deployment, raising the value of Sandisk’s product mix. If those customers demand qualified products and dependable supply, the company may retain better economics than a simple commodity-volume model would suggest. The bear case is that broader NAND capacity eventually catches up while device customers resist higher prices. Both can happen even if data-center units keep growing.
The valuation depends on which earnings persist
Short interest stood at 5,618,213 shares on September 15, about 3.8% of float and 0.56 days to cover. Those outstanding positions do not identify whether holders were trading memory prices, valuation or something else.
There is stronger protection than the quarterly mix alone suggests. On August 13, Sandisk said eight structured customer agreements covered roughly half of fiscal 2027 bits and two-thirds of fiscal 2028 bits, with minimum financial guarantees. Bit coverage is not the same as revenue coverage. Management’s fiscal 2028–2030 model targets about 80% adjusted gross margin and 50% adjusted free-cash-flow margin. Those are forward non-GAAP targets, but they directly challenge a simple assumption that current profitability must rapidly revert.
Sandisk Corporation had 128 hedge-fund holders in Q2 2026 in Insider Monkey’s hedge fund database, up from 114 in Q1. That increase of 14 captures wider historical participation rather than a verdict on how long current margins will last.
Fiscal fourth-quarter net income was $6.90 billion, compared with $11.43 billion for the full year. Multiplying the latest quarter by four produces $27.61 billion, putting the market capitalization at about 9.2 times that illustrative annual pace. That is not a forecast or a seasonally adjusted earnings estimate. It simply shows why the stock can appear much cheaper when investors choose a recent-quarter denominator.
A middle case of $15 billion in sustainable annual net income would imply about 17 times earnings. At $10 billion the multiple becomes roughly 25.5; at $7.5 billion it rises to 34. A lasting improvement in mix could justify the middle case, but record gross margins make it unsafe to assume the most recent quarter represents an ordinary year.
The company reported an 84.6% GAAP gross margin for the quarter and guided to an 83% to 84.9% GAAP range for the next one. Those figures support strong near-term profits. They also raise the size of the downside sensitivity: on fiscal 2026 sales, each 10-point margin reduction would remove roughly $2 billion of gross profit before other changes. Lower pricing could reduce revenue as well, making that fixed-sales calculation an incomplete downside case.
Sandisk Corporation has a growing data-center franchise and contractual protection extending beyond it. An attractive stock price still requires profits across the whole business to endure. The most useful test is whether contracted volumes, edge demand and cash conversion support the long-term margin targets as industry supply expands.
