That is overwhelmingly bullish, not evidence that analysts generally expected SanDisk shares to fall. The bearish case is instead a scenario built around a possible NAND-price reversal, peak-cycle earnings, supply catching up with demand and execution or trade risks.
What the bearish case actually says
SanDisk’s recent results are exceptionally strong, which is precisely why some investors worry that the current earnings level may be temporary. Memory markets have historically moved through sharp booms and downturns. When demand accelerates, NAND average selling prices (ASPs) can rise quickly and manufacturers’ margins expand. When producers add capacity or improve output faster than demand grows, prices can fall just as quickly.

The downside thesis is not that SanDisk’s business is currently weak. It is that the market may be valuing unusually high profits that could normalize later. If NAND prices decline, revenue, gross margin and earnings could all weaken. A lower valuation multiple may then be applied to those reduced earnings, even if the company remains profitable and long-term data-center demand continues.

That is a risk scenario rather than a guaranteed prediction. The available analyst tally contradicts an unqualified claim that Wall Street expects an imminent decline.

The numbers that make price normalization important
SanDisk reported fiscal 2026 revenue of $20.25 billion, up 175% year over year. Fourth-quarter revenue reached $8.97 billion, and revenue increased 51% sequentially. Management said approximately one-third of that sequential increase came from higher volume and two-thirds from higher pricing.
That mix matters. Growth generated mainly by shipped bits and customer adoption can be more durable than growth generated mainly by a temporary increase in ASPs. If pricing retreats, the portion of recent growth attributable to price can reverse even if unit demand remains healthy.
Datacenter revenue rose 437% year over year, showing how powerful current infrastructure demand has been. Management’s August 5, 2026 outlook for the first quarter of fiscal 2027 called for revenue of $10.30 billion to $10.80 billion and non-GAAP diluted earnings per share of $44 to $46. Those are company guidance figures, not reported results or an independent analyst forecast.
| Measure | Reported or guided figure | Why it matters to the debate |
|---|---|---|
| Fiscal 2026 revenue | $20.25 billion | Shows the scale of the current upswing, but does not establish that the level is sustainable through a full memory cycle. |
| Fiscal 2026 year-over-year revenue growth | 175% | Extremely rapid growth can raise questions about how much is cyclical pricing and how much is durable demand. |
| Q4 fiscal 2026 revenue | $8.97 billion | Provides the base for the 51% sequential increase reported by the company. |
| Q4 sequential growth mix | About one-third volume; two-thirds pricing | Makes a reversal in NAND ASPs a particularly important sensitivity. |
| Datacenter year-over-year growth | 437% | Supports the bullish argument that AI infrastructure is changing demand, while leaving open the question of duration. |
| Q1 fiscal 2027 management guidance | $10.30–$10.80 billion revenue; $44–$46 non-GAAP diluted EPS | Strong near-term guidance counters a simple claim that the business is already rolling over. |
Risk 1: NAND prices could fall after a supply catch-up
The central bearish risk is a change in the supply-demand balance. NAND producers can add wafer capacity, bring new facilities online, increase yields or transition to technologies that produce more bits per wafer. If that additional supply arrives after demand growth slows, customers gain bargaining power and ASPs can decline.
Rank #2

SanDisk’s Q4 growth split makes the exposure easy to see: two-thirds of its sequential revenue increase came from pricing. A price decline would not necessarily erase all demand, but it could reduce revenue per bit and compress gross margins. The effect can be amplified because memory producers have substantial fixed costs; lower prices spread those costs over fewer dollars of revenue.
What the 2028–2030 forecast means
Morningstar analyst William Kerwin wrote on August 6, 2026 that the key question is when NAND prices peak and how sharply they fall afterward. His forecast expected supply from SanDisk and peers to come online in 2028, putting pressure on prices, followed by a sharper downturn in 2029 and 2030. This is Morningstar’s forecast, not an established industry timetable or a consensus prediction.
Investors using that scenario are effectively asking whether today’s pricing power survives until new supply arrives. A delay in capacity, stronger-than-expected AI demand or disciplined production could postpone the downturn. Faster capacity expansion or weaker deployments could bring it forward.

A low price-to-earnings ratio does not automatically mean a cyclical memory stock is undervalued. If earnings are near a cycle peak, the denominator in that ratio may be unusually high. Once profits normalize, the apparent discount can disappear without any increase in the share price.
Axios described this as the longstanding Wall Street concern about memory cyclicality. Mark Newman, a memory analyst with Bernstein Research, said: “Multiples are low because of the perceived un-sustainability of earnings,” and added, “I would argue that the multiple is now effectively pricing an imminent collapse in profits.” Those comments describe a valuation interpretation, not a verified forecast that SanDisk’s profits will collapse.
The practical test is whether investors are capitalizing through-cycle earnings or current peak earnings. A company can report excellent cash flow and still carry a vulnerable valuation if the market believes those results cannot persist.
Risk 3: AI demand may change the cycle—but may not eliminate it
The bullish response is that AI data centers require much more memory than earlier computing workloads. Gil Luria, an analyst covering memory for D.A. Davidson, told Axios: “Memory is how AI happens. The GPU can’t do an AI transaction without memory,” followed by, “We can’t possibly have enough of it.” This view argues that AI creates a structural demand source capable of absorbing new NAND supply.
The unresolved issue is economic durability. AI demand must remain strong enough, and customers must continue spending at a pace high enough, to offset additional production. Deployment schedules can change, customers can optimize memory usage, and infrastructure investment can become more selective. AI demand therefore supports the countercase, but its existence alone does not prove that current ASPs or margins are permanent.
Rank #4
| Question | Bear interpretation | Bull interpretation |
|---|---|---|
| Price versus volume | Recent growth relied heavily on ASP increases, which can reverse. | Higher-value products and sustained bit demand can preserve revenue even if pricing moderates. |
| Supply timing | New capacity from SanDisk and peers pressures prices from 2028, with a sharper fall in 2029–2030 in Morningstar’s forecast. | Capacity may arrive later, be absorbed by demand or be restrained by producer discipline. |
| AI demand | Data-center spending could slow before supply is absorbed. | AI workloads create a larger, more durable memory requirement than prior consumer cycles. |
| Valuation denominator | The market is valuing unsustainable peak profits. | Investors are underestimating structurally higher through-cycle earnings. |
Risk 4: customer concentration and forecasting uncertainty
SanDisk identifies changes in relationships with key customers, customer consolidation and difficulty forecasting demand as risks. Memory demand depends on deployment timing, inventory decisions and product launches, all of which can shift between quarters.
Longer-term agreements can improve visibility for the portions of the business they cover, but they do not automatically eliminate exposure to price resets, volume changes or customer concentration. An agreement may specify commitments for particular products, capacities or periods rather than guarantee every sale at today’s ASP. Investors therefore need to distinguish revenue covered by durable commitments from spot or renegotiable business.
Risk 5: manufacturing, partnerships and technology execution
SanDisk’s annual filing identifies product-ramp delays, manufacturing and supply-chain disruptions, product defects, competition and technology transitions as potential causes of weaker results. These risks can matter even when end-market demand is healthy.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Ramp timing: Delays can postpone revenue or leave the company unable to meet customer schedules during a favorable pricing window.
- Manufacturing and supply chain: Disruptions can reduce output or raise costs, limiting the benefit of strong ASPs.
- Product quality: Defects can lead to returns, remediation costs or lost customer confidence.
- Technology transitions: A late or costly transition can weaken competitiveness or reduce manufacturing efficiency.
- Kioxia relationship: Reliance on strategic relationships, including Kioxia, creates partnership and execution exposure that investors must consider alongside SanDisk’s own operations.
Risk 6: tariffs, trade policy and the broader economy
SanDisk says adverse economic conditions, tariffs and trade-policy changes can increase costs, weaken demand or reduce margins. In its fiscal 2026 filing, the company reported that most products sold in the United States were then exempt from tariffs, while warning that changed rates or the loss of exemptions could be harmful.

That exemption status was a report-date condition, not a permanent guarantee. A policy change can affect input costs, customer purchasing decisions, shipment routes or the profitability of particular products. A weaker economy could also reduce electronics, enterprise and data-center spending independently of NAND supply.
What the analyst ratings actually show
A third-party ratings-page snapshot accessed October 13, 2026 listed 21 Buy, 3 Hold and 1 Sell among 25 analysts. Ratings can change, and the tally may reflect different broker coverage, update dates and aggregation methods. It should not be read as a precise probability of a share-price decline.
| Rating | Analysts in the October 13 snapshot | Interpretation |
|---|---|---|
| Buy | 21 | Strongly positive published view at that snapshot date. |
| Hold | 3 | Neutral or balanced risk-reward assessments. |
| Sell | 1 | A minority bearish view. |
| Total | 25 | Not evidence that analysts broadly expected shares to fall. |
The correct reading is that a bearish valuation argument exists alongside a mostly bullish analyst consensus and strong company guidance. Some investors may expect a fall because they believe the market is extrapolating peak earnings, but the ratings snapshot does not support attributing that expectation to analysts generally.
How to evaluate the downside scenario
- Track ASPs separately from bits: Determine whether revenue growth is coming from price, volume, product mix or a combination.
- Watch supply additions: Compare announced or expected capacity from SanDisk and peers with actual demand growth and inventory conditions.
- Test AI durability: Look for evidence that data-center demand remains broad and recurring rather than concentrated in a temporary deployment wave.
- Separate contracted from exposed sales: Identify which agreements provide volume visibility and whether they protect price, volume, or only a limited portion of revenue.
- Normalize earnings: Consider margins and profits under lower ASP assumptions instead of valuing the company solely on current results.
- Monitor execution: Follow ramp schedules, yields, technology transitions, product quality and the Kioxia relationship.
- Recheck external exposure: Review tariff exemptions, trade rules, customer concentration and macroeconomic conditions because each can change independently of NAND demand.
The bottom line on why shares could fall
The strongest bearish argument is that SanDisk’s exceptional earnings and pricing power represent a cyclical peak. A supply catch-up could push NAND prices lower, reduce margins and expose a valuation built on unusually high profits. Morningstar’s 2028–2030 timing is one analyst forecast, not a settled schedule. Customer concentration, forecasting difficulty, manufacturing execution, the Kioxia relationship and tariff policy add independent ways for results to disappoint.
The counterevidence is substantial: fiscal 2026 revenue reached $20.25 billion, datacenter revenue grew 437%, Q4 growth was supported by both volume and pricing, and management guided to another strong quarter. AI could make memory demand structurally larger than in past cycles. The October 13 ratings snapshot—21 Buy, 3 Hold and 1 Sell—also shows that analysts were not broadly expecting a near-term fall.
SanDisk shares therefore hinge on a specific debate: will AI and other data-center demand absorb new supply and support durable through-cycle earnings, or will NAND prices normalize before that demand can do so? The answer determines whether today’s valuation looks like a bargain on sustainable profits or a low multiple applied to peak-cycle earnings.
