SanDisk's Split Personality: A $94 Billion Backlog Meets a Market That Can't Make Up Its Mind

SanDisk posts record backlog and beats estimates, but analysts split on whether NAND pricing boom is sustainable or cyclical.

There aren't many stocks that can post a 371 percent revenue surge and still leave investors arguing about whether the story is genuinely good or merely cyclical noise. SanDisk has managed exactly that. The memory-chip maker finds itself in the unusual position of having secured the largest order backlog in its corporate history while simultaneously watching its share price swing with a violence that suggests the market remains deeply unconvinced about what comes next.

The headline numbers are hard to dismiss. Fourth-quarter revenue came in at $8.96 billion, a year-over-year jump of 371.59 percent, while earnings per share of $39.25 blew past the consensus estimate of $33.28. Gross margin climbed to 84.6 percent. Management's guidance for the current quarter points to revenue between $10.3 billion and $10.8 billion, with EPS expected to land in the $44 to $46 range.

The engine behind this momentum is a historic surge in NAND flash pricing. TrendForce estimates contract prices jumped 70 to 75 percent in the spring quarter, with another 10 to 15 percent increase expected in the current period. That pricing power is the foundation of the bull case, but it also raises a nagging question: how much of this growth is real demand versus a cyclical spike that will eventually reverse?

The $94 Billion Question

SanDisk's so-called NBM agreements — long-term customer commitments totaling $93.9 to $94 billion — represent what the company describes as an unprecedented milestone. JPMorgan's Harlan Sur has anchored his $2,250 price target to precisely this backlog, while also pointing to a NAND market that he expects to expand from $70 billion in 2025 to $300 billion this year and $500 billion next. Evercore ISI has similarly highlighted the company's long-term target of 80 percent gross margins.

Following the investor day and earnings release, analysts collectively raised their fair-value estimates from roughly $1,773 to $2,126 — an increase of about 20 percent, built on higher revenue growth assumptions and a margin forecast that was lifted to 68 percent.

Yet the analyst community is far from unified. While JPMorgan remains firmly bullish, Jefferies and Citi pulled back their price targets in August. Mizuho reaffirmed its Outperform rating on Monday but trimmed its target to $1,875 — a cautious adjustment that looks almost conservative given the scale of the company's stated ambitions.

One Seeking Alpha commentator flagged a detail that cuts to the heart of the debate: two-thirds of the recent sequential revenue growth came from price increases, with only one-third attributable to actual volume growth. For investors betting on structural market share gains, that's a sobering statistic. For those riding the cyclical pricing wave, it's exactly what they signed up for.

A Tale of Two Trades

The positioning of major institutional players tells its own story. Jane Street Capital disclosed in a regulatory filing that it has built its position to 7.41 million shares — roughly 5.47 percent of all outstanding stock — making SanDisk the firm's second-largest single equity holding. That's a meaningful shift for a house known for quantitative, market-making strategies rather than long-term conviction bets.

Meanwhile, CEO David Goeckeler sold 2,333 shares across two days in mid-August at prices between $1,596.08 and $1,600.62. The transactions were routine — proceeds went to cover tax obligations from the vesting of stock options, a standard occurrence for executives at public companies. Still, the optics of an insider trimming while a major quant fund loads up capture the current mood perfectly.

David Tepper's Appaloosa fund took the opposite route, exiting its SanDisk position entirely in the second quarter and rotating into Broadcom — a company with its own AI accelerator chips and a stated goal of more than $100 billion in AI revenue by fiscal 2027. That move reads as a bet against the commodity nature of memory chips in favor of companies with more differentiated product lines.

The Tape Tells Its Own Story

The stock's price action reflects this ambivalence. At €1,270.00, SanDisk trades roughly 38 percent below its 52-week high of €2,060.00, which was touched as recently as June. It remains 46 percent above the €870.00 low from late July. The annualized 30-day volatility of 135 percent tells you everything about how nervous the market is handling this name.

After the investor day sent the stock up nearly 14 percent, the shares have since gained another 21 percent before giving some back. The stock closed Tuesday down 5.9 percent over seven trading sessions, sitting 11 percent below its 50-day moving average — a clear sign that the short-term momentum has cooled.

On the technology front, the industry is undergoing a generational shift. The transition from tungsten to molybdenum in layer counts beyond 300 is expected to dramatically reduce leakage and boost bit density by more than 16 percent, according to SemiAnalysis. SanDisk and its partner Kioxia currently sit at 218 layers — behind SK Hynix, which is already mass-producing at 375 layers. That's a gap worth watching.

The Bottom Line

SanDisk is a textbook cyclical story being debated at what may be its peak. The contracted billions and the prospect of 80 percent gross margins are real and impressive. Equally real is the fact that the recent pullback and the departure of prominent investors suggest the market is beginning to distinguish between structural strength and cyclical tailwinds.

The question isn't whether SanDisk benefits from the memory boom — the customer commitments, the Kioxia partnership on QLC flash technology, and the long-term planning through fiscal 2030 make that clear. The question is who wants to own this trade at what price. Jane Street has made its choice. The CEO has made his. Both can be right, which is precisely why this stock remains one of the most difficult reads in the semiconductor space.
