SanDisk's Record Quarter Collides With a Market Demanding Even More

SanDisk's blowout Q4 revenue and 437% datacenter growth couldn't offset soft Q1 guidance, triggering an 11% stock drop and analyst split on NAND cycle peak.

There's a particular kind of Wall Street whiplash that comes when a company delivers blowout numbers and still gets punished for them. SanDisk shareholders experienced exactly that this week, watching the memory chip maker's stock tumble more than 11 percent on Thursday to $1,199.31 — despite fourth-quarter revenue that most competitors would envy.

The disconnect isn't hard to explain. It's the same cyclical logic that has governed the storage industry for years, and it's currently pointing toward a peak in the NAND flash cycle just as the company's forward guidance came in below what the most optimistic investors had hoped.

The Numbers Tell One Story

The headline figures are genuinely impressive. SanDisk posted fourth-quarter revenue of $8.97 billion, a 51 percent sequential increase, while full-year 2026 sales reached $20.25 billion — up 175 percent year over year. GAAP net income for the quarter came in at $6.90 billion, with the full year totaling $11.43 billion, or $73.76 per diluted share. The non-GAAP gross margin climbed to 84.6 percent, supported by "New Business Model" agreements that now cover long-term revenue commitments exceeding $93.9 billion.

The growth engine was unmistakable: the datacenter business surged 437 percent, aided by a shift toward higher-value customers and firmer pricing. On paper, these are results that would normally trigger celebrations.

Guidance Creates the Friction

The problem emerged with the outlook. For the first quarter of fiscal 2027, SanDisk guided to revenue between $10.3 billion and $10.8 billion — solid, but short of the $11.1 billion that some on the buy side had been targeting. That gap between "good" and "good enough" proved decisive.

CEO David Goeckeler acknowledged the structural tension during the earnings call, saying the company wants to escape the "boom-and-bust pattern" that has historically defined the memory business and instead build deeper, more predictable customer relationships. It was a candid admission, but also a reminder of just how cyclical this industry remains.

The selling continued into Friday, with shares closing at €1,050.00, down 4.55 percent on the day. Over the past 30 days, the stock has shed 30.92 percent and now trades nearly 30 percent below its 50-day moving average. The drawdown has cut the share price roughly in half from its 52-week high. Observers attributed the decline to profit-taking after an extended rally, concerns about the NAND cycle peaking, and the widening divergence between robust datacenter demand and a softer consumer market.

Wall Street Splits on What Comes Next

The analyst response following the August 6 results was notably fractured. Goldman Sachs' James Schneider maintained his buy rating with a $2,200 price target — at the time, implying roughly 63 percent upside. Jefferies took a more cautious stance, slashing its target from $3,000 to $1,750 on margin concerns while keeping a buy recommendation. Evercore ISI's Amit Daryanani trimmed his target from $3,100 to $2,800 but retained an outperform rating. Citi's Asiya Merchant cut hers from $2,500 to $2,100, citing a "muted" pricing outlook for the September quarter.

Mizuho, Wells Fargo and Bank of America also reduced their targets, with Wells Fargo noting that average selling prices hadn't risen as much as competitors'. RBC Capital, meanwhile, moved its target higher, and Morgan Stanley confirmed its buy stance. A Seeking Alpha contributor even raised a target to $3,300. The resulting range of price targets is exceptionally wide — a sign of how divided the Street remains on the trajectory of the memory cycle.

Notably, none of the major firms abandoned their positive ratings. That suggests the recent weakness has more to do with expectation management than any fundamental deterioration.

Insider Moves and Institutional Shifts

The shareholder picture is more mixed. Fidelity (FMR LLC) cut its stake by 41.29 percent to 7,861,064 shares, representing about 5.30 percent of the company, just before the earnings release. Jane Street, in contrast, established a new position of 5.00 percent, or 7,409,437 shares. Chief Legal Officer Bernard Shek sold 600 shares at an average price of $1,162.16 under a pre-arranged Rule 10b5-1 trading plan — routine activity that carries little signal.

Management has also signaled confidence through capital allocation. The board authorized an additional $14 billion buyback program, bringing total remaining repurchase capacity to $15.5 billion.

The Longer-Term Bet

Beyond the immediate noise, SanDisk is positioning itself for the next phase of AI infrastructure. Together with SK hynix, the company published the technical specification for High Bandwidth Flash (HBF) on August 3 through the Open Compute Project. The format supports stacked configurations of eight to sixteen NAND chips, capacities up to 512 gigabytes per stack, and bandwidth ranging from 0.4 to 3.0 terabytes per second — designed specifically for AI inference workloads. Google and Tenstorrent have since joined the consortium, and SanDisk reinforced the message at the FMS 2026 trade show with a keynote titled "NAND: The Versatile & Scalable Foundation of the AI Era."

Whether that long-term wager offsets the near-term cyclical pain remains an open question. The upcoming investor day on August 13, where Goeckeler and CFO Luis Visoso are expected to detail the roadmap for BiCS10 technology and enterprise SSD production scaling, should offer some clarity. The next quarterly report is scheduled for November 5.

For now, the market is wrestling with a fundamental tension: record margins, nearly $94 billion in contracted revenue and a hefty buyback program argue against any structural breakdown, while the cyclical logic of the NAND market keeps volatility elevated. The recent selloff may prove to be a pause rather than a reversal — but in this industry, the difference between the two is often only visible in hindsight.
