SanDisk Earnings Strong, Shares Fall

SanDisk earnings on Aug. 5, 2026 showed a stronger-than-expected quarter on revenue and profit, but shares fell after the company issued Q1 guidance that left traders questioning how long the firm's unusually high margins can hold.

Quarter Results and Scale

SanDisk reported fiscal fourth-quarter revenue of $8.97 billion, GAAP net income of $6.90 billion, and non-GAAP diluted earnings per share of $39.25. Fiscal 2026 revenue totaled $20.25 billion, up 175% year over year. The company described the quarter as materially larger in scale compared with prior periods, reflecting significant growth over the past year.

Sequential revenue rose 51%, with about one-third of the increase attributed to higher volumes and two-thirds to higher pricing. This pricing mix contributed to the elevated profit margins that investors scrutinized when assessing the outlook.

Guidance and AI Demand

SanDisk set Q1 fiscal 2027 revenue guidance at $10.3 billion to $10.8 billion and non-GAAP EPS guidance at $44 to $46. Market reaction focused on the guidance midpoint, which did not significantly exceed elevated expectations, prompting questions about the sustainability of the quarter’s high margins.

Data-center revenue climbed 103% sequentially to $2.98 billion, driven by AI-related storage demand. Management highlighted AI infrastructure orders and supply agreements as providing improved visibility over multiple years, supporting longer-term growth prospects despite near-term investor caution.

The company’s investor materials showed no merger, antitrust, or SEC filing events linked to the earnings release. The only related corporate action was an extension of joint-venture agreements with Kioxia at the Yokkaichi plant, separate from the quarter’s results. The combination of a strong quarterly performance, cautious guidance, and investor focus on margin durability suggests near-term trading may remain volatile, though the emphasis on multi-year AI demand could limit further declines.
