SanDisk Shares Plunge After Q1 Outlook Disappoints
SanDisk (SNDK) shares dropped over 6% after the company’s Q1 revenue outlook slightly missed Wall Street expectations. In its fiscal Q4, adjusted EPS was $39.25 vs $34.96 expected, and revenue rose to $8.97B vs $8.48B. For the September quarter, it projected revenue of $10.3B to $10.8B and adjusted EPS of $44 to $46, with data center revenue up sequentially.
How this was made

The 30-second read
Why it matters
Traders are likely focusing on the revenue outlook for the September quarter, using it to reassess near-term demand and pricing assumptions despite improved margins and enterprise AI storage momentum.
Market read
A guidance-driven repricing event for SNDK, with the market weighing near-term revenue softness against improving gross margin and data center growth.
What to watch
Committed supply agreements (eight contracts, $93.9B value over four years) may support longer-term pricing, potentially reducing the durability of the selloff.
Background
SanDisk reported stronger-than-expected fiscal Q4 results but issued September-quarter revenue guidance with a midpoint slightly below Wall Street expectations.
Ticker impact
SanDisk shares dropped over 6% after its September-quarter revenue midpoint (10.3-10.8B) came in slightly below expectations.
Near-term downside bias as traders reprice the revenue outlook; upside depends on whether data center momentum offsets weaker consumer demand.
The article ties the selloff directly to guidance being slightly below consensus, while highlighting offsetting positives (Q4 EPS beat, gross margin improvement, data center revenue growth).
Market effects
Signals that NAND/memory demand expectations remain fragile even with data center strength, potentially pressuring sector sentiment.
Primarily US-listed semiconductor/storage sentiment; limited direct regional spillover described.
Could influence global read-across for enterprise AI storage and NAND pricing discipline, but no new macro/regional catalyst cited.
Counterpoint
The guidance miss is modest at the revenue midpoint, while Q4 fundamentals improved (EPS beat, gross margin up, data center revenue more than doubled).
