SanDisk just delivered the most profitable quarter in its short life as a public company, and the stock fell anyway. That contradiction is worth unpacking carefully, because the outcome of this selloff will depend entirely on one number most headlines have not focused on: $93.9 billion.
Why This Stock Matters Now
Revenue of $8.97 billion surged 372% year-over-year and 51% sequentially, and non-GAAP EPS of $39.25 beat the consensus estimate by more than 13%. Yet the market’s attention quickly shifted to the forward outlook, where Q1 FY2027 revenue guidance of $10.3 billion to $10.8 billion came in below analyst expectations of approximately $11.1 billion, triggering the selloff. Shares slumped by more than 9% before the start of U.S. trading.
The knee-jerk reaction is understandable. When a stock has already climbed more than 460% in a single calendar year, the market is not pricing in good results. It is pricing in results that exceed already-elevated expectations. SanDisk exceeded on everything except the one metric that drives short-term momentum trades: the forward revenue midpoint.
The Investment Thesis
The selloff creates a gap between what the business is actually doing and what the stock price is implying. The thesis is simple to state and hard to hold: SanDisk is not a traditional commodity memory company anymore. Its contract structure, if durable, turns the memory cycle from an existential threat into a manageable risk. The question is whether investors will wait for proof of that durability, or exit now while the stock still reflects peak-cycle optimism.
The Business Behind the Stock
Fiscal 2026 revenue climbed 175% year-over-year to $20.25 billion as the company benefited from a shift toward higher-value customers and stronger pricing. Data center revenue rose 437% for the full year, underscoring growing demand for AI infrastructure and enterprise storage.
Data center revenue surged 103% sequentially to $2.98 billion driven by AI demand, while non-GAAP gross margin reached 84.6% versus 26.4% a year earlier. A margin expansion from 26% to nearly 85% in twelve months is not a small shift. It reflects the degree to which hyperscaler demand has overwhelmed available NAND supply.
The company said that revenue growth came from approximately one-third higher volumes and two-thirds higher pricing. That mix matters. Pricing-driven growth is more vulnerable to cycle reversal than volume-driven growth. It is also more profitable while it lasts.
What’s Changing: The $93.9 Billion Floor
The most consequential disclosure from Wednesday’s earnings call was not the guidance miss. It was the New Business Model contract update. NBMs are multi-year customer agreements covering supply, volume, and pricing. Pricing includes fixed and variable components, with floors and ceilings designed to protect acceptable margins even if market prices decline.
The $93.9 billion figure represents minimum contracted revenue at floor pricing across all NBM agreements. Eight clients have entered into contracts guaranteeing a minimum revenue of $93.9 billion at floor pricing. The contracts carry a weighted average term of more than four years. The floor value amounts to 4.6 times projected sales for fiscal 2026.
Around 50% of fiscal 2027 bits and close to 66% of 2028 bits are already secured. Those are not soft commitments. SanDisk CFO Luis Visoso said directly on the call: “The total expected revenue from all our NBMs we have signed is a minimum of $93.9 billion, assuming floor pricing. We believe actual revenue will be above that minimum.”
In its Q4 earnings presentation, SanDisk said it expects customer demand to grow faster than its supply and bits to remain allocated beyond calendar 2027. Based on a TechInsights market report, management estimates the NAND market could exceed $300 billion in 2026 and reach $500 billion in 2027.
The Valuation Problem
The gap between what the stock looks like today and what it might look like in two years is enormous, and that gap is the entire debate. At the $1,350.50 closing price of August 5, SNDK traded at approximately 19 times fiscal 2026 non-GAAP EPS of $70.88. However, annualizing the $45 midpoint of Q1 guidance produces a $180 EPS run rate and an apparently much lower multiple of 7.5 times.
A potential investor is therefore not deciding whether 7.5 times earnings is cheap. The real decision is whether $180 is remotely representative of sustainable annual earnings. That is the question the NBM contracts are supposed to answer. If the floors hold and the NAND shortage persists into 2028, the stock at current levels looks very different than if pricing normalizes sharply in calendar 2027.
The company authorized an additional $14 billion share buyback, signaling strong liquidity. As of July 3, SanDisk reported $4.76 billion in cash and no outstanding debt. Adjusted free cash flow for the fourth quarter came in at $5.04 billion, after accounting for contract payments and joint-venture adjustments. A company generating $5 billion in free cash flow per quarter with zero debt has significant flexibility. The buyback is not theater.
The Risks
The bear case is well-established. The bear case is simply the idea that NAND is a commodity. Commodity margins eventually return to the mean. Floor pricing in the NBM contracts protects SanDisk to a point, but the floors were calibrated to conditions that existed when the deals were signed. The multiyear supply partnerships lock in committed supply and financials, offering some cash flow stability, but may be vulnerable if NAND prices fall 40% or more by 2027.
Even though those long-term contracts may dampen volatility, an unprecedented wave of new NAND supply is expected to enter the market, starting in early 2027. That is the timing risk that makes the guidance miss feel more threatening than it might otherwise be. If new supply arrives before contract floors have been tested, investors will not wait for the test results.
Citi maintained a Buy rating on SanDisk but lowered its price target to $2,100 from $2,500, citing a more “muted pricing” outlook for the September quarter. Wells Fargo cut its price target to $1,400 from $1,620 and kept an Equal Weight rating, pointing to valuation concerns after the stock’s recent rally. When both the bulls and the neutrals cut targets on the same morning, the price action tells you the market has elevated its probability estimate for a cycle turn.
What Investors Should Watch Next
The company has scheduled an Investor Day for August 13, making this a two-part information event rather than a normal standalone earnings release. That date now carries more weight than it did before Wednesday’s call. Management needs to answer three questions: at what price level do the NBM floor provisions actually activate, how much new supply from Chinese NAND producers hits the market in 2027, and whether BiCS10 can hold the technology lead that has justified premium pricing.
BiCS10 applies advanced lateral scaling techniques to achieve industry-leading 1Tb TLC memory density greater than 29Gb per square millimeter, improving bit density by 59 percent while delivering up to 4.8Gb/s interface speed. If that lead translates into customer stickiness, the pricing floors become more credible. If competitors close the gap, the floors become the ceiling.
Bottom Line
SanDisk’s selloff is not a statement about the last quarter. The last quarter was genuinely exceptional. SanDisk did not disappoint investors with its reported quarter. It disappointed a market that wanted the next quarter to be even further above expectations. That is a meaningful distinction for investors with a time horizon longer than one earnings cycle.
The stock remains a bet on one unresolved question: whether $93.9 billion in contracted minimum revenue can survive contact with a NAND market that has historically punished every company that believed the good times were permanent. The Investor Day on August 13 is where management either validates the contract architecture or reveals its limits. That is the session worth watching more carefully than any earnings call this year.
