SanDisk earnings analysis: questions answered and next catalysts
SanDisk earnings analysis: questions answered and next catalysts
SanDisk (SNDK) just delivered its strongest fiscal year on record — FY2026 revenue of $20.25B (+175% YoY) and Q4 EPS of $39.25 (+13.5% beat) — yet the stock fell 4.0% today (and was down as much as 13% pre-market) because Q1 FY2027 revenue guidance of $10.3B–$10.8B landed below the Street’s most optimistic expectations of ~$12.3B. When the bar is set by elevated expectations, even strong results can disappoint.
The numbers that rewrote the record books
SanDisk Corporation (SNDK): Trading at $1,296.34 (-4.01% today) || Q4 Revenue: $8.97B (beat by +$550M) || Non-GAAP Gross Margin: 84.6% || Q4 EPS: $39.25 (vs. $34.59 est.)
Four consecutive earnings beats:
| Quarter | EPS Surprise | Revenue Beat | Price Reaction |
|---|---|---|---|
| FY2026 Q4 (Aug 5) | +13.5% | +$550M | -6.6% to -13% |
| FY2026 Q3 (Apr 30) | +59.7% | +$1.22B | +11.5% |
| FY2026 Q2 (Jan 29) | +77.7% | +$360M | +9.2% |
| FY2025 Q4 (Nov 6) | +37.1% | +$160M | +10.6% |
Q4 was the largest beat, yet it triggered the largest selloff. Expectations had simply run too far ahead.
Questions this earnings answered
1. Can margins hold above 80%? — Answered definitively. Non-GAAP gross margin hit 84.6% in Q4, up from 78.4% in Q3, and Q1 guidance calls for 83%–85% — margins are structurally elevated, not a one-quarter result. Evercore ISI noted margins "well ahead of consensus" with NBMs ensuring they stay above 80% as agreements ramp.
2. Is AI/data center demand real and durable? — Confirmed. Data Center revenue grew +437% YoY for full FY2026 to $5.15B, growing from ~30% to ~50% of the total NAND market. The NAND market itself is projected to exceed $300B in 2026 and approach $500B in 2027.
3. Are New Business Models (NBMs) gaining traction? — Locked in. SanDisk secured 10 NBMs covering $93.9B in long-term revenue guarantees, with $16.5B in customer financial guarantees to back them. NBMs will represent >50% of bits in FY2027 and ~two-thirds in FY2028 — this is a structural shift from spot-market NAND selling to contracted, premium pricing.
4. What drives the revenue mix? — Clarity delivered. Two-thirds of Q4’s sequential growth came from higher pricing, one-third from volume — confirming pricing power over commodity-cycle dependency.
5. Capital return conviction? — The board approved an additional $14B share repurchase authorization, bringing total remaining buyback capacity to $15.5B against a Q4 free cash flow of $5.0B (56% margin).
Questions still open
1. Are NAND contract prices peaking? — The market’s biggest concern. Morgan Stanley flagged on Jul 21 that memory contract prices may be peaking in Q4 2026 — triggering an 8.6% drop in SNDK before earnings even arrived. CEO David Goeckeler’s mid-teens decline forecast for PC/smartphone unit shipments this calendar year feeds that concern.
2. How transformative is High Bandwidth Flash (HBF)? — SK Hynix and SanDisk just announced the first-ever HBF standard specifications this week. HBF sits between HBM (high-bandwidth memory) and SSDs — potentially a new $B-scale market. Customer interest is described as "significant," but revenue contribution timelines are undefined.
3. Can SanDisk close the HBM gap vs. Micron? — Today’s sector selloff showed Micron (MU) fell only 2.3% vs. SNDK’s 6.6% — the market is rewarding Micron’s HBM exposure for AI accelerators. SanDisk’s NAND-centric model is being discounted relative to DRAM/HBM peers.
4. NBM execution risk — $93.9B in commitments is substantial, but with $16.5B in guarantees extended to customers, the question is: what happens if hyperscaler capex cycles turn? The visibility is real, but so is the concentration risk.
Next catalysts on the radar
| Catalyst | Timing | What to Watch |
|---|---|---|
| Analyst Day | Next week | HBF roadmap, capital allocation detail (Evercore flags this as the key event) |
| Q1 FY2027 Earnings | ~Nov 2026 | Can guidance of $10.3B–$10.8B be beaten again? |
| HBF Commercial Ramp | FY2027 | First revenue from the SK Hynix consortium |
| BiCS10 Production | FY2027 | Follow-on to BiCS8 majority production — cost/density leap |
| NAND pricing data | Monthly | Industry spot/contract price checks — the Morgan Stanley concern in real time |
| NBM expansion | Ongoing | New customer signings beyond the current 10 agreements |
The analyst divide
Goldman Sachs reiterated Buy / $2,200 PT — views the selloff as an expectation reset, not a fundamental crack.
Evercore ISI maintained Outperform, cut PT to $2,800 — still sees +116% upside from current levels, points to analyst day as the re-rating catalyst.
RBC Capital stays Sector Perform, raised PT to $1,300 — acknowledges the beat but questions whether the narrative has run ahead of execution risk.
InvestingPro Fair Value: ~$1,440 — implying ~11% upside from today’s $1,296.
The bull/bear divide hinges on one question: Is this a peak-pricing cycle top or a secular AI storage re-rating that’s just getting started? Next week’s Analyst Day is likely the most important near-term event to answer that.
