SanDisk's Data-Center Windfall Faces a Capacity Test
Published on 11/11/2026 at 08:11 | Editorial boerse-global.de
CoreWeave's blowout quarter has handed SanDisk a fresh demand signal, but the same morning brought warnings that the memory industry's own building boom could eventually erode the margins underpinning the stock.
CoreWeave reported revenue of $3.66 billion, up 168 percent year over year, with a backlog of $132.5 billion. The figures put memory makers back in the spotlight — and for SanDisk, the read-through is direct. Data centers are a key growth engine, and capital spending there supports volume prospects as long as it translates into additional storage demand.
That dynamic was already visible in the quarterly results and outlook published roughly two weeks ago. SanDisk's data-center revenue climbed 61 percent sequentially to $4.8 billion, and management expects data-center bit demand to rise 40 percent in 2027.
A Profitability Story First
Volume is only half the equation. What matters just as much for the valuation is the price SanDisk can command, and here the company has been riding a memory shortage that keeps supply behind demand. In the first quarter of fiscal 2027, gross margin reached 85.1 percent, while operating cash flow came in at $6.36 billion — evidence of just how much the favorable pricing environment has done for the bottom line.
The warnings circulating today take aim at any assumption that such exceptional profitability simply continues. A model cited in media reports illustrates the risk: if the operating margin fell from 73 percent to 10 percent, the price-to-earnings ratio could climb to 100. That is a scenario, not a forecast for SanDisk's actual business trajectory — but it frames the debate over how long the good times can run.
Should investors sell immediately? Or is it worth buying SANDISK?
Supply Is Coming, Just Not Yet
The bull case rests on a prolonged shortage. BofA expects a memory super-cycle through 2028, an assessment that favors SanDisk provided demand keeps absorbing the industry's production build-out.
New capacity, however, takes time to arrive. Micron's fab in Singapore is slated to begin wafer production in the second half of 2028, while SK hynix's M17 fab is scheduled to start in early 2029. That leaves the central test sitting between near-term earnings strength and later supply growth: CoreWeave's numbers bolster the demand side of the equation, but SanDisk must hold its pricing power once the additional plants come online for the valuation to stay genuinely cheap.
Guidance Is the Yardstick
Against that backdrop, the operative reference point remains the quarterly figures and outlook released about two weeks ago. SanDisk reported revenue of $11.03 billion for the first quarter of fiscal 2027, along with adjusted earnings per share of $49.51.
The company's own targets sit above those results. Revenue guidance of $12.2 billion to $12.6 billion points to higher sales than the reported quarter, and adjusted EPS is expected at $55 to $57. Execution against those numbers deserves particular weight given the risks under discussion — it would be a stronger argument for the shares than a short-lived rally alongside the sector.
Politics Adds a Second Variable
Tuesday's trading offered a reminder of how fragile sentiment remains. SanDisk fell 2.5 percent as investors weighed election-related uncertainty over AI infrastructure spending and concerns about the NAND price cycle, according to media reports. The pullback came only a day after SanDisk and Micron had recovered alongside other memory names — a rebound that reportedly followed the selloff about a week earlier and the election-driven worries about AI spending tied to it.
That swing between recovery and renewed weakness argues for taking political uncertainty seriously as a valuation risk. A more convincing case emerges once business performance strengthens confidence in SanDisk's targets. The growth-oriented outlook speaks for the company — provided it delivers.
