Why This Company Now

SanDisk is the #1 name on today's US VolumeSurge by a wide margin — $11.6B of turnover, roughly ten times the #2 name (Cleveland-Cliffs at $1.2B) — in a screen where Technology supplied 10 of the 27 passing names. The trigger is the rebound, not the run: SNDK closed +5.53% at $1,371.12 on Monday 19 October after a 23% seven-session drawdown through 16 October, a selloff sparked by China's CXMT disclosing next-generation DRAM progress — a product SanDisk does not make — while Micron's pricing read-through and a stabilising memory tape did the lifting on the way back. FQ1 2027 results land after the close on 29 October, with guidance already set at $10.3–10.8B of revenue and $44–46 of non-GAAP EPS.

🔄 Second Look — 77 Days Later

Last covered on 4 August 2026 at roughly $1,288, before the FQ4 print. Since then trailing EPS has gone from about $29 to $73.76 while the share price is up only ~6% — the multiple collapsed from ~44x forward to ~6.4x. The question is no longer whether the AI-storage cycle is real; it is how much of the peak is contractually locked in.

Financial Snapshot

Year	Revenue ($M)	Rev Growth	Op Margin	Net Income ($M)
FY2022 (Jul '22)	9,754	+75.3%	12.5%	1,064
FY2023 (Jun '23)	6,086	−37.6%	−21.3%	−2,143
FY2024 (Jun '24)	6,663	+9.5%	−6.7%	−672
FY2025 (Jun '25)	7,355	+10.4%	6.9%	−1,641
FY2026 (Jul '26)	20,248	+175.3%	61.6%	11,433
Q4 FY2026 (Jul '26)	8,965	+371.6% YoY	78.5%	6,903

FY2022–FY2025 span the carve-out and the 21 February 2025 separation from Western Digital; FY2025's GAAP net loss sits below a positive $507M operating line. Q4 FY2026 is shown separately because it reset the run-rate: non-GAAP EPS of $39.25 beat the $33.28 consensus, gross margin reached 84.6%, and roughly two-thirds of the 51% sequential revenue growth came from pricing.

Bull vs Bear

✅ Bull Case

Contracted demand is the whole ballgame. $93.9B of New Business Model agreements at floor pricing, $16.5B of financial guarantees and more than 50% of FY2027 bits already committed — visibility no prior NAND cycle has had. Management: demand is growing faster than supply.
The multiple no longer prices a supercycle. Q1 guidance of $44–46 EPS on $10.3–10.8B revenue implies a ~$180+ annualised run-rate; at $1,371 the stock trades ~6.4x forward with $6.3B of net cash and a $15.5B buyback authorisation (~7.7% of the market cap).
Datacenter is now a real second leg. Segment revenue reached $5.15B in FY2026 (+437%) and $2.98B in Q4 alone (+103% QoQ); BiCS8 and the SK hynix HBF standard (512GB, 3TB/s, released through OCP) move SanDisk into AI inference memory, not just consumer flash.

🔴 Bear Case

84.6% gross margin is a peak-cycle number. Two-thirds of Q4's sequential growth was price, not volume, and this business ran at −21% and −7% operating margins in FY2023–24. NAND has never sustained a margin regime like this one.
China supply is the new bear thesis. CXMT's DRAM progress alone took 23% off the stock in seven sessions through 16 October, even though SanDisk makes no DRAM. The uncontracted half of FY2027 bits is fully exposed to a YMTC/CXMT NAND ramp.
The tape is broken and fast money is leaving. Price sits 14% below the 50-day ($1,596) and 42% below the $2,354 high, beta is 3.6, 10 of 18 tracked funds trimmed in Q3 (D.E. Shaw, Millennium, Two Sigma among them), and the CEO sold $21.9M of stock.

Verdict

In August this was a momentum chase at ~44x forward earnings; today it is a contracted AI-storage cash machine at single-digit forward earnings, and that is a materially better setup. The catch is that the earnings are peak-cycle and the market has decided to treat every Chinese memory headline as a SanDisk headline — so own it as a sized, volatile position into the 29 October print, not as a core compounder.
