SanDisk's $94 Billion Contract Backlog Has Wall Street Split on Whether the Memory Cycle Is Finally Dead

SanDisk's $94B backlog and 80% margins suggest a structural shift, but wide analyst targets reveal lingering boom-bust risks.

The most contradictory chart in semiconductors right now belongs to SanDisk. The stock has surged 60 percent in two weeks, analysts are tripping over themselves to raise price targets, and a hedge fund that bet heavily on the shares just got crushed. All of it stems from one question: is the company actually breaking the memory industry's notorious boom-bust cycle, or is this just another sugar high?

The answer, on balance, leans yes — with caveats.

The Contracts That Changed the Conversation

Thursday's investor day was the catalyst. SanDisk laid out a financial model for fiscal 2028 through 2030 projecting revenue growth in the mid-to-high teens, a gross margin around 80 percent, an operating margin near 75 percent, and free cash flow at roughly half of sales. Those numbers alone would have turned heads.

But the real foundation is the backlog: eight long-term supply agreements, including with three US hyperscalers, totaling approximately $94 billion in contract value, backed by $16.5 billion in financial guarantees. Those contracts cover more than half of 2027's bit production and roughly two-thirds of 2028's output.

This is where the bull case diverges from mere price-chart euphoria. NAND flash has spent decades as a commodity business with brutal pricing cycles. When a majority of production is locked in under multi-year contracts with price protections, the quality of earnings changes fundamentally — regardless of what the spot market is doing on any given day.

JPMorgan's Harlan Sur, who initiated coverage with an Overweight rating and a $2,250 price target, argues the long-term agreements structurally reduce cyclicality. It's a compelling read of the numbers, and arguably stronger than the raw share-price reaction.

The Numbers Support the Narrative — For Now

The latest reported results back the story. Fiscal fourth-quarter revenue came in at $8.96 billion, up 371.6 percent year over year (the secondary report puts the figure at $8.97 billion), while earnings per share of $39.25 blew past the $33.28 consensus. Management guided first-quarter EPS to between $44 and $46 on revenue of $10.30 billion to $10.80 billion.

The quarter's sequential growth split roughly one-third from higher volumes and two-thirds from higher prices — evidence that the current memory shortage is driving margins more than unit shipments. For the full fiscal year 2026, SanDisk reported revenue of $20.25 billion.

A $14 billion share buyback program is underway, with management pledging to return all excess free cash flow to shareholders. Melius analyst Ben Reitzes has gone so far as to sketch a potential $100 billion buyback over three years, lifting his price target to $3,600.

Here's where caution kicks in. The target range across the Street is extraordinarily wide — from RBC's $1,600 to Bernstein's $3,000. That kind of dispersion isn't consensus; it's uncertainty about whether those margins can hold. Morgan Stanley, generally more cautious, concedes the margin targets "could be exceeded in the coming years" but warns they'll be hard to sustain long-term.

Even the Pros Can't Agree

The hedge fund Situational Awareness offers a cautionary tale. It had concentrated roughly half its US portfolio in SanDisk and Micron, only to absorb a 67 percent loss in July when SanDisk dropped 47 percent. The fund was forced to hand positions to Citadel, and its assets shrank from $45 billion to $10 billion.

David Tepper's Appaloosa Management also exited its roughly $400 million SanDisk position entirely in the second quarter — though reports suggest some re-entry since. When seasoned operators swing between full conviction and complete exit, certainty in either direction looks misplaced.

The stock closed Friday at €1,420.00, up 6.8 percent on the day and 35 percent for the week. That still leaves it 31 percent below its 52-week high of €2,060.00, suggesting the rally hasn't yet retraced old territory. The shares trade about 3 percent below their 50-day average of €1,460.50, and with annualized volatility at 145 percent, the swings are far from over.

The Structural Argument Wins — For Now

The contract structure with hyperscalers genuinely changes the business model, not just the narrative. That's the strongest argument for owning the stock. But the extreme volatility and the wide divergence in price targets argue for sobriety.

Investors who believe the NAND cycle has been structurally tamed will see the contracts running through 2028 as the real value driver. Those who doubt it won't be surprised by the next sharp correction. Both camps have evidence on their side — which is exactly why the chart looks the way it does.
