SanDisk (SNDK) stock faces a major test after Wednesday’s earnings as investors look beyond another expected revenue beat. According to Visible Alpha, the company may report fiscal fourth-quarter revenue of $8.71 billion and adjusted earnings of $35.45 per share.

Those estimates exceed SanDisk’s guidance ceiling of $8.25 billion in revenue and $33 in adjusted earnings. That gap matters because the market has already been rewarding memory shares for tighter NAND supply and firmer pricing, so even a solid print may not be enough unless management shows the gains can last. Investors now want proof that strong NAND prices, data-centre demand, and new supply agreements can support growth into fiscal 2027.

SanDisk Stock Must Beat Raised Expectations

Revenue near $8.71 billion would be more than four times the $1.90 billion reported a year earlier. Even so, results within management’s original range may still disappoint because the market has already lifted its expectations.

Options expiring Friday priced a move of about 14.9% in either direction. That range placed the shares between roughly $1,211 and $1,635, based on Tuesday’s close near $1,428. Options measure expected volatility, not market direction.

In fiscal third-quarter results, SanDisk’s data-centre revenue rose 233% sequentially to $1.47 billion. TLC enterprise SSD sales drove much of that growth, while consumer revenue fell 10% over the same period.

The company also expects its high-capacity QLC Stargate products to begin generating revenue in fiscal Q4. Investors will be watching enterprise SSD shipments, NAND selling prices, bit growth, production costs, and gross margin guidance, since those figures will help show whether recent operating strength is broadening beyond one quarter.

July Selloff Raised Peak-Cycle Concerns

SanDisk stock fell 46.6% in July before the company reported any confirmed demand weakness. Micron and other memory shares also declined, indicating that investors reduced exposure across the broader memory sector.

The selloff reflected concern that high NAND margins may not last. Near-term contract prices could rise 10% to 15% in the September quarter, but faster supply growth could pressure prices in the second half of 2027.

Fiscal 2027 Guidance Is the Key Test

SanDisk’s earnings call and August 13 Investor Day must provide clearer targets for fiscal 2027. Investors want more detail on sustainable margins, enterprise SSD demand, customer agreements, and revenue visibility.

Evercore ISI estimates that five agreements may cover about $62 billion in minimum revenue, backed by more than $11 billion in guarantees and prepayments. Investors want evidence that these commitments can protect cash flow if NAND prices weaken.

Analysts will also look for contract terms covering prices, volumes, guarantees, and cancellation rights. That detail will help clarify how much of SanDisk’s recent momentum is tied to specific customer commitments rather than near-term market conditions. Strong results may support SanDisk stock, but guidance will need to show that earnings can remain firm after the current NAND shortage eases.
