SanDisk's Explosive Growth Story Hits a Wall of Skepticism as NAND Pricing Fears Mount
Published on 08/09/2026 at 19:10 | Redaktion boerse-global.de
There are moments when a company's financial results and its stock price seem to be describing two entirely different businesses. SanDisk is living through precisely such a moment right now. The memory-chip maker has just delivered the strongest fiscal year in its recent history, generated billions from an AI-driven datacenter boom, and launched a massive share buyback — yet investors have responded by wiping nearly a third off the share price in a single month.
The Numbers Tell a Story of Unprecedented Demand
The fourth quarter of fiscal 2026 was nothing short of spectacular. Revenue came in at $8.97 billion, representing a 51 percent jump from the preceding quarter and a 372 percent surge year over year. GAAP net income reached $6.90 billion, translating to diluted earnings per share of $43.97, while the non-GAAP figure stood at $39.25. For the full fiscal year, revenue totaled $20.25 billion — a 175 percent increase from the prior year.
What makes these figures particularly striking is the composition of the growth. According to company statements, two-thirds of the sequential increase came from higher pricing, with only one-third attributable to greater volume. That mix cuts to the heart of the current NAND market dynamics: it isn't just that demand is exploding — suppliers are also regaining significant pricing power.
Nowhere is this more evident than in the datacenter segment, where revenue climbed 437 percent over the fiscal year, buoyed by a shift toward higher-value customers and improved pricing. Since the company's April earnings call, SanDisk has signed five additional "New Business Model" agreements — three with new clients and two expanding existing contracts. The total NBM pipeline, based on minimum prices, is projected to generate at least $93.9 billion in revenue. CFO Luis Visoso was quick to note that actual volume is expected to exceed that floor.
Should investors sell immediately? Or is it worth buying SANDISK?
A Buyback That Says One Thing, a Market That Says Another
The board's response to this momentum was to authorize an additional $14 billion share repurchase program, bringing total remaining authorization to $15.5 billion. A company aggressively buying back its own stock typically signals confidence in its valuation — yet the market's reaction suggests that message isn't landing.
On Friday, shares closed at €1,050.00, down 4.55 percent on the day. Over the past month, the stock has shed 30.92 percent — a brutal correction for a company with this kind of growth narrative. The stock now sits roughly 49 percent below its 52-week high of €2,060.00, while trading about a fifth above its 52-week low of €870.00.
The disconnect isn't rooted in the reported numbers themselves but in mounting anxiety about what comes next. Several analysts trimmed their price targets on Thursday, citing concerns about weakening NAND pricing heading into the September quarter. Jefferies cut its target from $3,000 to $1,750 while maintaining a Buy rating, with analyst Blayne Curtis pointing to softening NAND price momentum as the key factor. Wells Fargo's Aaron Rakers lowered his target from $1,600 to $1,420, keeping an Equal-Weight rating. Evercore ISI's Amit Daryanani reduced his from $3,100 to $2,800 while reaffirming a Buy recommendation.
Yet not every firm is moving in the same direction. RBC Capital actually raised its target from $1,000 to $1,300 on the same day, though it held steady with a neutral stance. This striking divergence — one house slashing targets dramatically, another daring to push higher, both maintaining their fundamental ratings — underscores just how uncertain professional observers are about the sustainability of the current pricing cycle.
Looking Ahead to a Defining Moment
For the current quarter, SanDisk has guided to revenue between $10.30 billion and $10.80 billion, with non-GAAP earnings per share of $44.00 to $46.00. Those figures nominally exceed the just-reported quarterly results, yet they failed to sway investors.
The company also made headlines with a technological announcement, teaming up with SK hynix to publish the technical specification for High Bandwidth Flash (HBF) through the Open Compute Project. The technology targets AI inference systems and aims to address memory solutions for compute-intensive workloads — a space where multiple memory manufacturers are currently jockeying for position.
Adding another layer of complexity, a regulatory filing revealed that Chief Legal Officer Bernard Shek sold 600 shares at an average price of $1,162.16. The transaction was executed under a pre-arranged trading plan pursuant to Rule 10b5-1, which allows executives to schedule trades independently of short-term market movements.
SANDISK at a turning point? This analysis reveals what investors need to know now.
Ripples Beyond the Company Itself
The SanDisk story extends beyond its own shareholder base. Former parent Western Digital reported fiscal Q4 2026 revenue of $3.75 billion, up 44 percent year over year, with a GAAP net income of $3.195 billion that included a valuation gain from its remaining equity stake in SanDisk — a reminder that the memory maker's stock performance carries financial consequences well beyond its own investors.
The technical picture reflects the broader uncertainty. The stock currently carries a Relative Strength Index of 41.5, placing it in neutral territory, while annualized 30-day volatility sits at roughly 154 percent. That combination of tepid momentum and extreme price swings captures the market's current state of mind.
SanDisk has scheduled an investor day for August 13, where management will have the opportunity to demonstrate how durable its growth promises truly are. Until then, the stock serves as a case study in how, in today's memory market, operational excellence alone no longer guarantees share price stability. The AI boom has transformed the storage industry into a supercycle where prices can explode within months — and just as quickly reverse course. Investors are no longer rewarding record quarters; they're already trading the next turn of the cycle.
