Sandisk reports Q4 revenue up 372% YoY to $8.97B, above $8.5B est., data center revenue of $2.97B, and forecasts Q1 revenue below est.; SNDK drops 5%+
The midpoint of the company's revenue forecast was below what analysts had been modeling — Sandisk's stock was falling on Wednesday afternoon.
Context & Ripple Effects
Sandisk’s latest outlook interrupts a run of accelerating reported growth: its Q2 results were attributed to AI-driven demand, followed by Q3 revenue that exceeded estimates and a Q4 guide above expectations. The new report pairs a much larger data-center revenue contribution with a Q1 midpoint below the analyst model.
That makes the forward guide—not the reported quarter—the immediate test of whether the demand trajectory implied by the prior Q3 beat and raised Q4 outlook can sustain at the pace investors had priced in.
First-order effects
- Sandisk shares fell more than 5% after the below-estimate Q1 forecast, despite Q4 revenue of $8.97 billion exceeding expectations.
- Analysts modeling Sandisk’s next quarter must reset revenue assumptions downward, while the company’s reported $2.97 billion in data-center revenue becomes the central indicator of demand durability.
Second-order effects
- The gap between a Q4 beat and softer Q1 guide shifts investor attention from backward-looking growth rates to Sandisk’s order visibility and sequential demand trajectory.
- Western Digital, which previously planned a discounted sale of a Sandisk stake, is exposed to the same share-price sensitivity to Sandisk’s forward outlook.
Third-order effects
- If similar guide-down reactions persist, storage suppliers will be valued less on peak-period revenue growth and more on the reliability of their contracted or visible demand through the semiconductor cycle.
The trend: AI-linked storage demand is producing exceptional reported growth, while forward guidance increasingly determines whether that growth is treated as durable or cyclical.
