Why Sandisk Stock Fell
According to TIKR, the trigger for Friday's selling was Kioxia, which guided below estimates and warned that the AI-driven surge in flash prices is fading, as reported by Bloomberg. TIKR said the selling spread through the memory sector, with Intel falling after a weak fourth-quarter guide tied to PC demand squeezed by memory costs.
The drop came a day after strong numbers. In its fiscal first-quarter earnings report on Thursday, October 29, Sandisk posted revenue of $11.03 billion against a $10.70 billion consensus and adjusted earnings of $49.51 per share against a $46.36 estimate, as reported by Benzinga. The company guided fiscal second-quarter revenue to $12.2 billion to $12.6 billion and adjusted earnings per share to $55 to $57.
Per TIKR, pricing is doing less of the work. CFO Luis Visoso put pricing at about 40% of the quarter's 23% sequential revenue gain, after higher prices drove about two-thirds of growth in the prior quarter, and management guided only to "modest" further price increases. Consumer revenue fell 29% to $397 million as buyers pushed back on higher prices.
Simply Wall St described the market as actively pricing the risk that high memory prices could weaken demand for the volumes Sandisk has under contract.
SNDK Stock Analysis: Supporting Factors and Risks
Supporting Factors
Profitability stayed high in the quarter, with a non-GAAP gross margin of 85.1% and adjusted free cash flow of $5.7 billion, according to Simply Wall St.
About half of fiscal 2027 bit volume and two-thirds of fiscal 2028 are now under contract, per TIKR.
CEO David Goeckeler said long-term supply deals are "leading to a tremendous pull on our portfolio," and Benzinga reported that the company sees a customer pipeline with financial commitments running through 2030.
Risks
Kioxia's warning that the flash price surge is fading adds to TIKR's point that pricing "has stopped doing most of the work."
Device demand is under pressure: Simply Wall St noted global smartphone shipments fell 20% while memory prices raised device costs by about 20%.
In the bear case Simply Wall St described, contracted volume commitments could be hard to meet without discounting if memory prices stay high enough to pressure demand.
Next on the calendar is Sandisk's 8-for-1 stock split, with split-adjusted trading starting November 20, according to TIKR.
