SanDisk's 85% Margin Is Only as Good as the Contracts Behind It

A 5.3% slide on Friday has put SanDisk back in the crosshairs of the memory cycle debate — and this time the argument isn't really about the share price.

Rising memory prices sound like good news for a NAND maker. Yet Friday's session was dominated by worries over competition and margins, with the stock shedding 5.3% as the broader memory sector sagged. Reports linked the move to concerns about price competition and the durability of SanDisk's gross margins, while spending on AI infrastructure also came under scrutiny. Two uncertainties collided: whether demand holds, and how the spoils get divided along the supply chain.

That combination is what makes the call difficult. Higher NAND prices would be a convincing argument for SanDisk only if the company can defend its margins in a more competitive field. Watching the direction of prices alone falls short. What matters is which economic benefits actually reach SanDisk — and how well they hold up.

Evercore's Counterweight

Evercore ISI offered a more optimistic read on Wednesday, reaffirming its "Outperform" rating and a $2,500 price target. The brokerage pointed to supply agreements with customers, discipline on the supplier side and robust AI-related demand.

That is a concrete counter to market skepticism. The supply deals and supply discipline speak for SanDisk — provided they support earnings power even when NAND prices shift. That is precisely where the bullish analyst call will be judged, beyond the next swing in sentiment.

A High Bar Set by the Numbers

SanDisk's results, published on 29 October, supply the economic backdrop to this dispute. They show strong growth paired with guidance for further gains, which sets the bar accordingly high for coming reports.

In the first fiscal quarter of 2027, SanDisk posted revenue of $11.031 billion — an increase of 378% year on year. For the second fiscal quarter of 2027, the company guided to revenue of $12.2 billion to $12.6 billion.

Profit guidance points upward too, though the calculation basis matters: the diluted figures cited under adjusted accounting refer to the basis before the stock split. SanDisk reported adjusted diluted earnings per share of $49.51 and guided to $55.00 to $57.00 for the following quarter.

BIT Capital's Full Exit

Against that backdrop, BIT Capital reported a US equity portfolio without SanDisk yesterday. The exit, which came to light today, cuts to the heart of the valuation debate: how durable are fat memory profits once prices retreat? SanDisk's multi-year contracts argue for better protection — as long as their price floors hold in a downturn. That is the test the cheap valuation must pass.

The stake disclosure covers the quarter through 30 September. SanDisk had previously ranked among the larger positions in the reported portfolio, at a 6.7% weighting. The filing does not reveal the timing or proceeds of the sale.

The exit is best read as a counterpoint to the optimistic valuation case. One institutional investor has unwound its position entirely, while analysts see opportunity after the selloff. What both decisions share is the question of earnings durability.

Cheap — If the Profits Carry

Bernstein analyst Mark Newman counts SanDisk among the stocks where he sees recovery potential after the selloff. That is a weighty argument, provided the earnings expectations underpinning it survive. Under such a valuation, the next price move matters less than the earnings level that can be sustained across a memory cycle.

The skeptical reading starts here: Bernstein expects memory prices to normalize from the second half of 2027 through 2028. For fiscal 2030, the earnings estimates of three analysts sit well below the consensus for the prior year. The low valuation and the expectation of falling profits therefore belong in the same thought. SanDisk looks especially cheap as long as investors accept today's high earnings as a durable base. Anyone assuming a sharp normalization has to lean harder on contractual protection.

Contracts Versus the Cycle

Add financial guarantees of just under $16.5 billion. This is the most interesting part of the SanDisk story: a cyclical commodity business is meant to become more predictable through longer-term commitments. The contracts speak for the company as long as their economic protection survives weaker market conditions. So far, the price floors have not been through a downturn.

According to SanDisk management, the minimum prices in multi-year contracts support a gross margin of roughly 80%. In the quarter through 2 October, gross margin reached 85.1%.

That scale explains why contract terms matter so much. If minimum prices keep the margin anchored at a high level, the cheap-valuation argument gains weight. If earnings fall sharply alongside memory prices, the size of normalized profits moves to center stage.

Market Share as the Second Test

Competitive position deserves attention alongside pricing. Counterpoint estimates SanDisk's share of global NAND revenue at 11% in the second quarter of 2026, down from 13% in the prior quarter.

That decline argues for assessing contractual protection and market position together. High margins make SanDisk attractive only if the company simultaneously defends its place in the NAND business. A shrinking revenue share belongs on the checklist right next to the expected price normalization.

The decisive yardstick, then, is the resilience of the business model in the next weaker pricing environment. SanDisk's contracts offer a concrete argument for steadier earnings. How much that argument is worth will be settled by whether minimum prices and customer commitments deliver the promised protection under stress.
