Micron, SanDisk swing after hours
- Sandisk drove the after-hours move on April 30, posting a blowout fiscal Q3 with sharply higher NAND pricing and datacenter sales, while Micron traded in sympathy. - The standout number was Sandisk’s 97% sequential revenue jump to $5.95 billion, plus fiscal Q4 guidance for $7.75 billion to $8.25 billion. - It matters because AI demand is now lifting memory pricing broadly — not just HBM, but NAND too.
Memory stocks were the real story after the bell on Thursday, April 30. Sandisk didn’t just beat expectations — it posted numbers that screamed pricing power, and that sent the whole memory trade moving. Micron got pulled into the move because investors now read these companies as part of the same AI-memory chain, even if they sell different mixes of products. The basic takeaway is simple: the market is starting to believe the memory boom is broader than just HBM. (investor.sandisk.com) ### What actually hit after hours? Sandisk reported fiscal third-quarter 2026 revenue of $5.95 billion, up 97% from the prior quarter, with GAAP net income of $3.62 billion and gross margin of 78.4%. The company also guided fiscal fourth-quarter revenue to $7.75 billion to $8.25 billion and non-GAAP EPS to $30 to $33. That is the kind of print that forces people to rethink the whole NAND market in real time. (investor.sandisk.com) ### Why did Sandisk move Micron too? Because Micron is already the market’s cleanest large-cap memory proxy. When Sandisk says outperformance came from “higher pricing” and a mix shift toward higher-value customers, traders immediately map that onto the rest of the memory co(investor.sandisk.com)NAND. (investor.sandisk.com) ### Is this just an HBM story? Not anymore — and that’s the important shift. HBM still matters because it is the most obvious AI bottleneck, and Micron has been one of the biggest public winners there. But Sandisk’s report showed that plain old NAND is also getting pulled hi(investor.sandisk.com)shiest corner of it. (investor.sandisk.com) ### What did Sandisk say that mattered most? Two things. First, datacenter revenue jumped to $1.47 billion from $440 million in the prior quarter — up 233% sequentially. Second, management said the quarter’s outperformance came from both higher pricing and a shift toward higher-value customers. That is different from a one-off shipment spike. It sounds more like a market where customers are competing for supply. (investor.sandisk.com) ### Where does Micron fit in now? Micron had already laid out the bullish version of this trade on March 18. It reported fiscal Q2 revenue of $23.86 billion and said demand, tight industry supply, and execution drove records across revenue, margin, EPS, and free cash flow.

Because memory stocks are brutally cyclical, and the market is always trying to figure out whether a spike is temporary or structural. Sandisk’s quarter looked structural. The company talked about multi-year customer engagements w(investors.micron.com)ess like spot-market chaos and more like a tighter, more durable earnings setup. (investor.sandisk.com) ### Does this spill into Nvidia, AMD, and Intel? Indirectly, yes. If memory suppliers are showing this much pricing power, it reinforces the idea that AI infrastructure spending is still running hot. That helps the broader read-through for accelerator demand and server build(investor.sandisk.com) economics. (investor.sandisk.com) ### Bottom line? The after-hours swing was really about one thing — Sandisk made the NAND market look much stronger than many investors thought. And once that happened, Micron stopped looking like a one-product AI winner and started looking like part of a wider memory repricing story. (investor.sandisk.com)
