SNDK · Q1 2026 Earnings

Sandisk

Reported November 6, 2025

30-second summary

Sandisk's first full quarter under the new guidance regime cleared the bar by a wide margin: revenue of $2.31B (+23% YoY, +21% QoQ) came in $108M above the high end of the prior guide, non-GAAP EPS of $1.22 was 36% above the high end of $0.70–0.90, and gross margin of 29.8% printed above the 28.5–29.5% guide. The Q2 guide is the real signal — revenue $2.55–2.65B and gross margin 41–43% imply ~1,150bps of sequential margin expansion, which management attributes to pricing (not cost-downs) and BiCS8 mix. Datacenter fell 10% YoY to $269M and is the one segment that did not participate, though it grew 26% QoQ and management framed CY26 as the year datacenter becomes NAND's largest end-market.

Guidance

Kioxia delivered a strong Q1 FY2026 beat on revenue (+4.9% above guidance) and Non-GAAP EPS (+35.6% above guidance) and raised Q2 FY2026 outlook dramatically, with revenue up 11–15% QoQ and gross margin expected to expand 1,100–1,320bps to 41–43%, suggesting accelerating demand and significant mix/operational leverage ahead.

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

Management tone

Quarterly-visibility cyclical → BiCS8 ramp story → strategic supplier with multi-year hyperscaler commitments.

A quarter ago the press-release framing was "exceeding our guidance" with HBF tagged as a future AI-inference paradigm; this quarter management explicitly states customers are "reaching out proactively and providing visibility all the way through calendar year 27." The shift from quarter-by-quarter to multi-year visibility is the most consequential change in the narrative — it converts NAND from a price-taker business into something closer to a long-term-contracted memory supplier, and it underpins the entire margin guide.

The second shift is structural market positioning. Last quarter Cloud was $213M, the smallest segment, and the company was still framed as a broad NAND supplier. This quarter: "Calendar year 26 will be the first time that data center market is the largest market in NAND. That's always been the mobile market." Management is now selling a thesis where Sandisk migrates from "underrepresented" in datacenter to participating in NAND's biggest end-market — and is making "strategic allocation decisions" to favor specific hyperscalers over breadth.

The third shift is the margin-driver framing. Last quarter Q1's ~280bps gross margin step-up was attributed to BiCS8 ramp. This quarter: "we stopped talking about cost declines a while back" and shifted to "pricing that we were implementing" with "double digits" increases expected. The Q2 guide of 41–43% gross margin — a 1,100bps+ step-up in a single quarter — is being underwritten by pricing power in a supply-constrained market, not cost-downs. That is a fundamentally different (and more fragile) margin model than the BiCS8-mix narrative of one quarter ago.

The fourth shift is on supply duration. Q4 framing had supply constraint persisting "through end of calendar year 26"; this quarter management says constraints push "beyond calendar year 26" and into 2027 based on customer commitments.

Recurring themes management leaned on this quarter:

Data center emergence as largest NAND market segmentSupply-constrained market extending into 2027Long-term customer commitments replacing spot market dynamicsBICS-8 technology enabling margin expansion and capacity growthEnterprise SSD qualifications across five hyperscalersAI-driven demand acceleration in data center exabytes

Risks management surfaced:

Market estimates for data center exabyte growth changing 'almost like every week or two'Q3 seasonality risk, with historical bit declines of 12-14% sequentially driven by consumer business weaknessLong-term agreements with hyperscalers still in early/nascent phase with uncertain termsHBF technology timeline slippage (memory in 2026, controller in 2027 remains target but 'work in progress')Wafer capacity constraints limiting ability to serve all customer demand even with allocation

Answers to last quarter's watch list

Gross margin delivery against the 28.5–29.5% Q1 guide. Delivered 29.8%, above the high end. More importantly, Q2 is guided to 41–43%, an 1,100bps+ sequential step-up that management ties to pricing and BiCS8 mix. The margin-recovery thesis didn't just hold — it accelerated.
Resolved positively
Cloud/Datacenter segment dollars and HBF pipeline. Datacenter (the renamed Cloud segment) printed $269M, clearing the $250M threshold, and grew 26% QoQ off the Q4 base. HBF was discussed as a multi-year initiative (memory in 2026, controller in 2027) but without a quantified pipeline. The qualification breadth (5 hyperscalers engaged, 2 qualifying) is the more substantive datapoint.
Resolved positively
Client segment YoY re-acceleration. The segmentation framework changed: Q4's "Client" ($1.10B, +3% YoY) and "Consumer" ($585M, +12% YoY) appear to have been recut into "Edge" ($1.39B, +30% YoY) and "Consumer" ($652M, +27% YoY). The new Edge category grew 30% YoY, which on a like-for-like basis is a sharp re-acceleration, but the segment redefinition makes direct comparison imprecise.
Not resolved
GAAP-to-non-GAAP gap. Q1 GAAP EPS of $0.75 vs non-GAAP $1.22 — a $0.47 gap, materially narrower than Q4's -$0.16 vs $0.29. GAAP turned solidly positive. The separation-charge bleed appears to be rolling off, though management didn't quantify it on the print.
Resolved positively
FY26 full-year guide. Still not provided. The only FY26 datapoint disclosed is the BiCS8 bit-share trajectory (majority of bits exiting FY26). Two quarters into the stated forward-quarter-and-FY cadence, the FY frame remains absent.
Continue monitoring

What to watch into next quarter

Q2 gross margin delivery against 41–43%. This is the single most important number in the entire FY26 setup. A 1,100bps+ sequential step-up in one quarter is unusual; if Q2 prints at the low end or below, the pricing-led margin model is in question. The bull case requires ≥41.0%.

Pricing realization disclosure. Management explicitly anchored the margin guide to "double digits" pricing increases. Watch whether next quarter quantifies the pricing component vs the BiCS8-mix component — if pricing is doing most of the work, the 2027 sustainability question becomes acute.

Datacenter YoY return to growth. Datacenter at -10% YoY but +26% QoQ implies a Q2 inflection. Watch whether Q2 datacenter revenue crosses $325M and turns positive YoY; if it doesn't, the "datacenter becomes NAND's largest end-market in CY26" thesis loses near-term proof.

Third hyperscaler + storage OEM qualification timing. Management committed to CY26 for the 3rd hyperscaler and top storage OEM. Any slippage of these calls into late CY26 or CY27 weakens the multi-year commitment narrative.

FY26 full-year guide. Third quarter in a row without one. Watch whether Q2 print finally supplies a revenue/margin envelope — the absence is becoming conspicuous given management's confidence on multi-year demand visibility.

HBF controller timeline. Memory targeted 2026, controller 2027, but management flagged the controller as "work in progress." Slippage of the controller into 2028 delays the HBF revenue contribution.
