Could SanDisk Be The Value Stock For Your Portfolio

SanDisk (SNDK) stock trades at 17.6 times earnings as of October 19, 2026, compared with 22.7 for the median S&P 500 company. This discount follows an 851% return over the past year, and the shares have fallen 25.6% in the past month. The current price appears to factor in an assumption that flash memory profits at SanDisk will not last. To qualify as a value stock, its profit has to be real cash and has to hold up when NAND prices stop rising. So is the profit behind that multiple backed by cash?

SanDisk's Profit Is Largely Backed By Cash

So far, the answer is largely yes. Over the four quarters ended July 3, 2026, SanDisk generated $11.7 billion of cash from operations alongside $11.4 billion of net income in fiscal 2026. Part of that cash came from customers: $2.48 billion of contract prepayments and deposits flowed into fiscal 2026 operating cash. Excluding them, SanDisk's adjusted free cash flow was $8.74 billion for the year, below net income. For fiscal Q4 2026 alone, adjusted free cash flow was $5.04 billion, compared with $7.08 billion before excluding $1.94 billion of those payments.

Much larger sales delivered that cash, with revenue rising 175.3% from the year before. Excluding one-time items, SanDisk retained 61.6% of its revenue as operating profit, compared with 18.5% for the median S&P 500 company.

The balance sheet adds to the value case. SanDisk ended July 3, 2026, holding $4.76 billion in cash and cash equivalents and no borrowings.

How Unusual Are These Margins?

Very. Excluding one-time items, the 61.6% operating margin for fiscal 2026 compares with 6.9% in fiscal 2025. On a reported basis, fiscal 2025 included a $1.83 billion goodwill impairment and ended in a net loss of $1.64 billion.

Price rather than volume drove most of this jump. On the August 5, 2026 call, management said higher pricing accounted for about two thirds of the revenue growth between fiscal Q3 and fiscal Q4 2026. The amount of storage SanDisk sold over the entirety of fiscal 2026 grew only in the mid-teens.

Management also said that pricing for the business outside its long-term contracts will fluctuate with the market. Profits built on high prices can shrink when those prices drop.

SanDisk Is Signing Multi-Year Contracts With Price Floors

Securing more storage volume under long-term contracts is management's solution. SanDisk currently holds contracts running up to five years with eight Datacenter and Edge customers, and management expects these agreements to yield at least $93.9 billion of revenue at floor prices.

Cash deposits and financial instruments totaling $16.5 billion back these customer commitments. Management expects margins to remain attractive even at floor pricing, projecting these contracts will cover more than half of the storage SanDisk sells during fiscal 2027. Revenue guidance for fiscal Q1 2027 sits between $10.3 billion and $10.8 billion, compared with $8.97 billion in fiscal Q4 2026.

Today's multiple is therefore measured against an exceptional margin year at SanDisk. Purchasing shares at this price is less a bet that the market has mispriced a steady business than a bet that these long-term contracts keep earnings near this level when NAND prices fall. The earnings behind that multiple would be far smaller if margins slide back toward the 6.9% SanDisk posted in fiscal 2025, excluding one-time items.

Cash largely backs the profit at SanDisk. The company has yet to show that the profit holds up when NAND prices change. The gross margin SanDisk reports for fiscal Q1 2027, due on October 29, 2026, is the number to watch against the 84.6% recorded in fiscal Q4 2026.
