SNDK · Q2 2026 Earnings

Sandisk

Reported January 29, 2026

30-second summary

Sandisk delivered Q2 FY2026 revenue of $3.025B (+61% YoY, +31% QoQ), $375M above the high end of the prior $2.55–2.65B guide, with non-GAAP EPS of $6.20 nearly double the $3.00–3.40 guide and non-GAAP gross margin of 51.1% landing ~810bps above the 41–43% guide. The Q3 FY2026 guide is the bigger event: revenue $4.40–4.80B (mid +52% QoQ), EPS $12.00–14.00 (mid +110% QoQ), and non-GAAP gross margin 65.0–67.0% — a further 1,390–1,590bps step-up on top of Q2's already-massive beat. Management is now framing this as a "structurally higher" margin level tied to datacenter mix and the upcoming Stargate/BiCS8 QLC ramp, not a cyclical bounce; datacenter +76% YoY to $440M finally cleared the bull-case threshold and is positioned to become NAND's largest end-market in 2026.

Guidance

Q2 significantly beat revenue and EPS guidance; company raised Q3 outlook and reset gross margin expectations to a structurally higher 65–67% level driven by datacenter mix and near-term Stargate product ramp.

Guidance is issued for both next quarter and the full year. Both may appear below.

Management tone

Cyclical recovery → BiCS8 ramp story → multi-year supplier commitments → structural margin reset and datacenter primacy.

A quarter ago management was selling a 1,100bps margin step-up as the proof point for the pricing-led recovery; this quarter they guided to another 1,390–1,590bps step-up on top of that, and explicitly relabeled it: "Margins are expected to reset at a structurally higher level, delivering fair returns on the substantial innovation and investment required." The verb tense shift from "expansion" to "reset" is the most important rhetorical move in the print — it converts the bull thesis from a cyclical upswing into a permanent industry repricing, and it commits management to defending a 60%+ gross margin floor going forward. If Q4 FY2026 prints below 60%, that commitment cracks.

The datacenter framing also hardened from forward-looking to declarative. Last quarter: "Calendar year 26 will be the first time that data center market is the largest market in NAND." This quarter: "data center is expected to become the largest market for NAND in 2026, driven by some of the world's largest and well-capitalized technology companies" — and they backed it with a +76% YoY print that finally validates the claim. The accompanying line that "data center is not the commodity NAND market...data center is NAND is a highly strategic product that's part of a very sophisticated AI architecture" is management explicitly arguing the datacenter mix earns a different multiple than the legacy book — a pricing-power argument, not a volume-growth argument.

The commercial-model shift accelerated from "customers reaching out proactively" to firm structural change: "We are engaged in discussions with customers to evolve from quarterly negotiations towards multi-year agreements with firmer commitments on supply and pricing." This is a generational change in how NAND is sold — moving from quarterly auction to long-term-contracted memory — and it underpins the entire structural-margin claim. The credibility of the 65–67% Q3 FY2026 guide depends on these contracts actually existing in writing, not just in discussion.

Finally, the supply-duration framing pushed out again. Last quarter said constraint through CY26; the prior quarter said beyond CY26; this quarter: "We continue to see customer demand well above supply beyond calendar year 2026, which requires careful allocation planning." The portfolio-allocation comment — "we're literally able to trade out the lowest margin business for now the highest margin business" — is the operational mechanism behind the margin reset, and it implies datacenter-share gains are coming at the explicit cost of de-prioritizing lower-margin consumer/edge business.

Recurring themes management leaned on this quarter:

AI-driven structural demand shift in data center becoming primary NAND marketGross margin expansion to structurally higher levels (51% Q2, 66% Q3 guidance) from low 30sTransition from transactional quarterly market to multi-year supply agreementsEnterprise SSD explosive growth (64% sequential Q2, expected to accelerate further)NAND as critical strategic component vs. commodity product in AI infrastructureSupply-demand imbalance requiring disciplined allocation to highest-value customers

Risks management surfaced:

Forward-looking statements subject to various risks and uncertaintiesActual results could differ materially from expectations regarding technology, business plans, and financial resultsVisibility into long-term demand still uncertain despite strong near-term signalsDependency on multi-year agreement adoption by customers changing decades-old business practicesPotential tax rate normalization as Malaysia loss carryforwards consume quickly

Answers to last quarter's watch list

Q2 FY2026 gross margin delivery against 41–43%. Delivered 51.1%, ~810bps above the high end of guide. The pricing-led margin model didn't just hold — it materially overshot. And the Q3 FY2026 guide of 65–67% extends the trajectory by another 1,390–1,590bps. The bull case has been validated for two consecutive quarters; the question shifts to whether 65%+ is defensible.

Resolved positively

Pricing realization disclosure. Not quantified separately from mix. Management's "trade out the lowest margin business for the highest margin business" framing implies mix is doing material work alongside pricing, but the specific split between pricing % and mix % was not disclosed. The 2027 sustainability question remains open.

Continue monitoring

Datacenter YoY return to growth. Datacenter printed $440M, well above the $325M threshold, and turned from -10% YoY in Q1 FY2026 to +76% YoY in Q2 FY2026 — the cleanest possible resolution. The prior framing of Q4 as a trough is validated.

Resolved positively

Third hyperscaler + storage OEM qualification timing. Management noted completion of PCIe Gen 5 TLC qualification at a second hyperscaler with additional hyperscaler quals on track "over the coming quarters," but no specific third-hyperscaler or storage-OEM milestone was named.

Continue monitoring

FY2026 full-year guide. Still not provided, despite the stated forward-quarter-and-FY cadence. Four consecutive quarters now without a full-year envelope. Given the magnitude of the Q3 FY2026 ramp and the "structurally higher" margin claim, the absence is increasingly hard to justify.

Resolved negatively

HBF controller timeline. Not addressed. Stargate (BiCS8 QLC storage-class product) was given a refined timeline of "shipping for revenue within the next several quarters" but that is a separate product from HBF. HBF controller (originally 2027 target) was not updated.

Continue monitoring

What to watch into next quarter

Q3 FY2026 gross margin delivery against 65–67%. Two consecutive quarters of margin guides being blown out gives the print credibility, but a 65%+ gross margin from a NAND supplier has no precedent. Below 65% calls the "structural reset" framing into question; above 67% reinforces the pricing-power narrative and triggers a re-rating debate.

Datacenter dollars crossing $700M. Q2 FY2026 datacenter at $440M needs to maintain or accelerate the +64% QoQ trajectory to keep the "largest NAND end-market in CY26" claim on track. Watch for a $700M+ print and whether QoQ growth holds above +40%.

Multi-year customer agreements moving from "discussion" to "signed." This is the single most important narrative dependency. Specific dollar value or duration of executed LTAs would materially de-risk the structural-margin thesis. Discussion-only language for a third quarter would erode credibility.

FY2026 full-year guide. The absence is now conspicuous. If Q3 FY2026 still does not bring a revenue/margin envelope, the gap between management's "demand visibility through CY27" claims and their willingness to commit to FY-level numbers becomes a governance question.

Stargate (BiCS8 QLC) revenue contribution. Management said "shipping for revenue within the next several quarters." Watch for first-revenue disclosure and any quantification of the contribution to the Q4 FY2026 or Q1 FY2027 mix — this is the product underpinning the next leg of margin expansion.

Tax rate normalization pace. Q3 FY2026 tax guide of $325–375M on implied pre-tax income of ~$2.3B suggests ~15% effective rate. Watch whether the rate steps up further as Malaysia loss carryforwards exhaust — material erosion of EPS leverage from here is the principal hidden risk in the model.
