Sandisk delivered another unusually large beat in fiscal Q4, with revenue rising 51% qoq to $8.97bn—above both consensus and the company’s $7.75bn–$8.25bn guidance—while non-GAAP gross margin reached 84.6%. The results were not purely a datacenter story: management attributed roughly two-thirds of the sequential revenue increase to higher pricing and only one-third to volume. Datacenter revenue nevertheless doubled qoq to $2.98bn, while new disclosures around $93.9bn of NBM commitments improved multi-year demand visibility. The central question is how much of the current earnings power can persist once NAND pricing growth moderates.
Will Datacenter account for at least 50% of Sandisk’s revenue in fiscal Q1 2027?
TL; DR: Key Takeaways
Q4 exceeded Sandisk’s guidance by an unusually wide margin. Revenue reached $8.97bn, up 51% qoq and 372% yoy, compared with an ~$8.56bn consensus estimate. Non-GAAP EPS of $39.25 also exceeded the estimated $35.13 consensus. Non-GAAP gross margin rose 620 bps qoq to 84.6%, versus the company’s 79%–81% outlook. Sandisk’s Q1 FY2027 guidance calls for revenue of $10.3bn–$10.8bn, non-GAAP gross margin of 83%–85% and non-GAAP EPS of $44–$46, suggesting limited near-term margin normalization.
Datacenter has become a material destination for Sandisk’s capacity. Datacenter revenue more than doubled qoq to $2.98bn and represented 33% of total revenue. More significantly, its share of company bits increased from 12% a year earlier to 38%. This supports the view that enterprise SSD growth is more than a pricing effect. Still, Edge remained the largest end market at $5.43bn, and future results must distinguish between higher datacenter bit shipments and higher NAND prices.
Pricing remained the largest earnings driver. Q4 revenue increased by $3.02bn sequentially, with management attributing roughly two-thirds of the growth to pricing and one-third to volume. Datacenter mix and the BiCS8 transition are supporting profitability, but the revenue bridge indicates that NAND pricing remains central to the 84.6% gross margin. The next test is not whether margins set another record, but whether they remain materially above historical levels as pricing contributes less to sequential growth.
NBM has moved from a strategic narrative to a measurable contract framework. Sandisk disclosed that eight Datacenter and Edge customers have signed agreements representing $93.9bn of minimum revenue at contractual price floors, including $59.8bn of quarter-end RPO, or $91.1bn after two post-quarter agreements. Cash deposits and financial guarantees total $16.5bn, while the contracts cover ~50% of FY2027 bits and ~67% of FY2028 bits. This primarily locks in multi-year supply and purchasing obligations, allowing Sandisk to plan capacity with greater certainty. It does not lock in current profitability: the guarantees cover only ~18% of minimum contract revenue, pricing contains floors and ceilings, and execution risks remain. NBM should therefore raise the cycle floor rather than eliminate the NAND cycle.
Cash generation was strong, although headline FCF benefited from contract payments. Q4 operating cash flow was $7.13bn and reported FCF was $7.08bn. After adjusting for NBM prepayments, deposits and Flash Ventures activity, FCF was $5.04bn—still substantial, but a better measure of underlying cash generation. Sandisk also added $14bn to its repurchase authorization, taking the remaining authorization to $15.5bn after completing $4.52bn of buybacks during Q4.
Key Debates
- Can non-GAAP gross margin remain above 80% as NAND pricing growth moderates?
- Will datacenter revenue and its share of total bits continue to rise together?
- How quickly will NBM commitments convert into recognized revenue and adjusted FCF?
- Will planned inventory growth support contracted demand or create future pricing pressure?
