Moat Score
One of the five NAND producers at scale, sharing wafer output with Kioxia through a joint venture extended to December 2034, with a growing book of take-or-pay supply contracts. The contracts are the moat news; the product itself is still a commodity bit.
Sandisk's edge is scale in a five-player NAND market plus multi-year contracts that turn spot exposure into committed volume, not a product competitors cannot make:
- New Business Model Agreements: Eight customers have signed multi-year NBM agreements with committed volumes and floor-and-ceiling pricing. Management puts the minimum expected revenue at $93.9B at floor prices, backed by $16.5B of cash deposits and financial guarantees, covering about half of FY27 bits and two-thirds of FY28 bits. That is more than four years of FY26 revenue under contract, the same structure that moved Micron's transaction embedding to strong.
- Kioxia Joint Venture Scale: Sandisk and Kioxia share the Yokkaichi and Kitakami fabs and split the wafer output, and the JV was extended through December 2034. The JV is how a company with no fabs of its own sits among the scale producers, and it is why bit growth in the mid-to-high teens comes from BiCS node transitions rather than new clean rooms. Samsung, SK hynix with Solidigm, and Micron run the same playbook at similar or larger scale.
- Datacenter Mix Shift: Datacenter revenue went from $213M in Q4 FY25 to $2.98B in Q4 FY26 as enterprise SSDs qualified at hyperscalers for AI storage. Qualification is real friction, but the same sockets are dual- or triple-sourced against Samsung, Solidigm, Kioxia and Micron, so it rates as embedding, not a lock.
Moat Verdict
Sandisk's moat is contracts on a commodity: transaction embedding is strong on $93.9B of NBM minimum revenue and $16.5B of guarantees, while process IP, scale through the Kioxia JV, talent and the retail brand are intact. None of it is AI-vulnerable software, and AI storage demand is the reason the contracts exist; the AI-era risk is the capex cycle, which sits in growth, not here.

The JV fabs in Japan receive government subsidies, as Micron's US fabs do under the CHIPS Act; peers hold the same class of support, so it bars entrants, not peers (rule M4).
No network effects in memory; customers buy on price, availability and qualification.
Eight customers on multi-year New Business Model agreements with committed volumes and floor-and-ceiling pricing: a minimum $93.9B of expected revenue at floor prices, $16.5B of cash deposits and guarantees, about half of FY27 bits and two-thirds of FY28 bits. The same contract structure as Micron's take-or-pay SCAs, at higher bit coverage.
Storage hardware, not an authoritative record of any business function.
Through the Kioxia JV, extended to December 2034, Sandisk shares wafer output from some of the largest NAND fabs, a barrier to new entrants. Samsung and SK hynix with Solidigm run comparable or larger capacity, so it is not a unit-cost lead over peers.
The SanDisk name carries retail shelf space in memory cards and portable drives, a separate source of durability from the datacenter book. Consumer is only $556M of Q4 FY26 revenue, so it moves little.
Moat in 5–10 years
Sandisk's moats hold at their current levels. The NBM book runs three to five years and covers two-thirds of FY28 bits, so the strong embedding is contracted for most of the horizon; renewals toward the end of the decade are the point to re-check, as with Micron's SCAs. Scale and IP hold at intact against Samsung, SK hynix, Kioxia and Micron, and YMTC adds supply rather than unwinding contracts.

Growth Score
Fiscal Q1 2027 (quarter to early October, reported October 29 after the close): revenue $11.03B, +23% QoQ and +378% YoY, above the $10.3–10.8B guide and ~$10.7B consensus. GAAP gross margin was 85.0%, non-GAAP EPS $49.51 (GAAP $52.60) against a $44–46 guide, and free cash flow $6.31B. Datacenter grew 61% QoQ to $4.80B; Edge rose 7% to $5.83B and Consumer fell 29% to $397M as bits went to higher-priced channels. Sandisk returned $5.0B through buybacks (~3.2M shares) and announced an eight-for-one split effective November 19, 2026. Fiscal Q2 is guided to revenue of $12.2–12.6B, gross margin 84.4–85.4% and non-GAAP EPS $55–57 (pre-split).
Valuation Score
Re-marked at the $1,330.05 close on October 29, 2026, before the fiscal Q1 print released after that close: 64 on the held $700 / $1,300 / $2,000 ladder (pre-split; the eight-for-one split is effective November 19), from 68 at the $1238.03 mark. The ladder, struck on October 26, is held: the quarter beat and the Q2 guide (EPS $55–57) runs above it, but the band is set off the cycle and the bear already prices a 2027 roll-over. The text below was written at the earlier mark. At $1,238.03 (October 23 close, ~$181B market cap) Sandisk is ~47% below its $2,354 52-week high and still up more than 400% this year. On the Q1 FY2027 EPS guide of $44–46 the run-rate multiple is ~7×; on FY2026's $70.88 it is ~17×. The ladder uses Micron's method so the two memory names can be read side by side: the base is ~12–13× a mid-cycle EPS near $100–105 (about 0.6× the guided run-rate, the same discount Micron's base takes), the bear is ~6–7× that mid-cycle figure with the NBM floor under it, and the bull is ~11× the run-rate. Spot is ~90% of the way from the $700 bear to the $1,300 base, for a valuation score of 68. The base is ~0.61× the ~$2,120 Street mean, the same far-below-Street shape as Micron (see the valuation-floor open call).

Growth Analysis
Growth Drivers
Key Risk
NAND pricing peaks in 2027 as Samsung, SK hynix, Kioxia and YMTC add bits and hyperscalers digest AI storage, so the half of FY2027 bits outside the NBM book reprices down. Falsifiable: gross margin below 50% for two consecutive quarters, or FY2028 non-GAAP EPS below $60 (FY2026 was $70.88), would mean the contracts cushioned the cycle rather than rewrote it. Western Digital's October 22 warning on rising input costs is the first sign to watch.
Score Derivation
80.7 base − 1.3 trajectory − 10 risk = 69
Base 80.7 (12–20% CAGR, midpoint 16%, set off the cycle per G5) − 1.3 trajectory (Datacenter accelerating; Edge and Consumer decelerating) + 0 stable margin (85% gross margin is at the peak, not expanding) − 10 high key risk = 69. The October 30 refresh moves Edge to decelerating (+48% QoQ in Q4 → +7% in Q1).

Memory at peak earnings trades at single-digit multiples, and Sandisk is there on the run-rate. The question the price asks is how far FY2028–29 earnings fall from a $180 annualised run-rate. The NBM floor pricing on half to two-thirds of bits is why the bear sits at $700 rather than at a full-cycle trough; the uncontracted half is why the base does not capitalise the run-rate.
Approximate figures as of October 23, 2026 (price $1,238.03).
Where We Are vs Targets
Loading live price…
NAND pricing rolls over in 2027 as supply catches up, the uncontracted half of bits reprices, and the stock trades at ~6–7× a mid-cycle EPS with the NBM floor holding the rest.
- Q1 FY27 lands at the low end of $10.3–10.8B and Q2 guides gross margin down as contract-price increases stall
- Samsung, SK hynix and YMTC bit additions push enterprise SSD prices down through 2027
- FY2028 consensus EPS falls toward $60, with NBM floors and guarantees preventing a deeper trough
FY2027 revenue near the ~$42B consensus, a digestion year in FY2028 cushioned by the NBM book, and the market capitalising a mid-cycle EPS of ~$100–105 at ~12–13×.
- Q1 FY27 delivers $10.3–10.8B and $44–46 EPS, and the NBM book keeps growing past eight customers
- Datacenter keeps gaining share of revenue as enterprise SSD qualifications broaden
- Gross margin settles well above prior-cycle peaks as contracted volume reduces spot exposure
AI storage demand keeps NAND tight into 2028, more of the book moves under NBM contracts at higher floors, and the market pays ~11× the guided run-rate.
- NBM coverage rises above two-thirds of FY28 bits at higher floor prices
- FY2028 EPS holds near the FY2027 run-rate instead of digesting
- Buybacks from the $15.5B authorisation shrink the share count materially
