Sandisk (SNDK) Q2 2026 earnings review
A Parabolic Move: Earnings Double Guidance, Then Guide to Double Again
Sandisk delivered a quarter for the history books, obliterating its own guidance and signaling a memory supercycle of rare magnitude. Q2 Revenue of $3.03B beat the high end of guidance by ~$375M, but the real story is profitability: Non-GAAP EPS of $6.20 nearly doubled the guidance ceiling of $3.40. The pricing environment has shifted violently in Sandisk's favor, driving Gross Margins from ~30% in Q1 to 51% in Q2. Guidance for Q3 is even more shocking: projecting ~50% sequential revenue growth and EPS doubling again to ~$13.00.
🐂 Bull Case
Gross margins expanded ~2100 basis points sequentially to 51.1%. Guidance for Q3 suggests margins will hit ~66%. This indicates a severe supply shortage where Sandisk can dictate pricing.
Datacenter revenue grew 64% QoQ and 76% YoY. Management cites 'accelerating enterprise SSD deployments' and AI tailwinds. The shift to becoming a data-center-first storage company is materializing rapidly.
🐻 Bear Case
When a commodity hardware company guides for 66% gross margins and $13 EPS (annualized ~$52 EPS run rate), the market often fears a cyclical peak. Sustainability of this pricing environment beyond 2026 is the primary long-term risk.
The company is likely on strict allocation. While pricing is great, the inability to capture unconstrained demand due to wafer limits (fabs at 100% utilization in Q1) could allow competitors to regain share.
⚖️ Verdict: 🟢🟢
Strong Bullish. The guidance for Q3 implies the company will earn more in one quarter ($13/share) than it did in the last three years combined. The magnitude of the margin expansion overshadows all other concerns in the immediate term.
Key Themes
Margin Expansion Velocity
The speed of margin expansion is historic. Non-GAAP Gross Margin moved from 29.9% in Q1 to 51.1% in Q2, and is guided to 66% (midpoint) in Q3. This confirms that the 'structural reset' and 'supply/demand imbalance' mentioned in Q1 have intensified significantly.
Datacenter Hypergrowth
Datacenter revenue hit $440M, up 64% sequentially. In the Q1 call, management noted they were 'underrepresented' in Datacenter but engaged with 5 hyperscalers. The Q2 numbers suggest these qualifications are turning into volume orders faster than expected.
Tax Expense Volatility
Non-GAAP Tax Expense guidance for Q3 is $325M-$375M, a massive jump from $22M in Q1. While a high-class problem driven by surging profits, investors must model a significantly higher tax burden going forward compared to the minimal taxes paid during the downturn.
Consumer Resilience
Despite Q1 warnings about Q3 seasonality, Consumer revenue grew 39% sequentially to $907M in Q2. The guidance for Q3 implies this strength continues, suggesting the 'consumer seasonality' fear was unfounded or completely overridden by pricing increases.
Other KPIs
Cash ($1.54B) now exceeds Total Debt ($603M: $20M current + $583M long-term). The company repaid $750M in debt during the quarter. This balance sheet strength allows maximum flexibility for capital returns.
Accelerating. Up from negative FCF in 25Q4 and significantly higher than 26Q1. The cash conversion is powerful, driven by the margin explosion.
Stable/Lean. Inventory decreased sequentially from $2.08B in Q4 25 and remained flat vs Q2 25, despite massive sales growth. This confirms the 'supply constrained' narrative; they are selling everything they can make.
Guidance
Accelerating dramatically. The midpoint ($4.6B) implies ~52% sequential growth. This contradicts historical seasonality patterns (Q3 is usually down) and confirms a massive pricing/volume supercycle.
Accelerating. Implies more than doubling Q2's record EPS of $6.20. The operating leverage at 66% gross margin is driving unprecedented profitability.
Accelerating. Up from 51.1% in Q2. This level of margin in hardware storage is exceptionally rare and indicates Sandisk has near-total pricing power.
Key Questions
Seasonality vs. Supercycle
In Q1, you explicitly warned about negative seasonality in Q3. Guidance now suggests 50% sequential growth. What changed so dramatically in the last 90 days—is this purely pricing, or has unit demand structurally shifted?
Sustainability of 60%+ Margins
Guidance implies 66% gross margins. Historically, memory cycles peak and correct. What structural changes (consolidation, AI demand) give you confidence these margins are durable beyond the next 2 quarters?
Supply Allocation Strategy
With revenue skyrocketing, are you currently capping demand due to wafer constraints? How much revenue is being left on the table, and does this open the door for competitors to take share in the Edge/Consumer markets?
Capital Allocation with Record Cash Flow
With EPS run-rating ~$50 and a net cash position, will you accelerate buybacks or consider initiating a dividend, or is the priority to horde cash for the next downcycle?
