SanDisk Corp. (SNDK) management has shared pivotal insights following its fiscal second-quarter 2026 earnings release this week, signaling that the current downtrend in this high-momentum stock is likely unsustainable. Key data from AlphaSpace reveals that SanDisk aggressively repurchased $4.5 billion of its own shares last quarter, leaving $14.5 billion remaining under its current buyback authorization. Citi analyst Asiya Merchant, after meeting with SanDisk's CEO and CFO on Friday, released a report suggesting the company will likely continue its share repurchase program.

Merchant summarized the core takeaways from the meeting: "Overall, the management team remains highly optimistic... This confidence is rooted in a vast addressable market. The company forecasts that the total addressable market for NAND flash memory in fiscal 2027 will reach approximately $500 billion, driven by the long-term demand from expanding AI inference scale, up from $300 billion in fiscal 2026. Management also highlighted an increasing conviction in demand sustainability. Major hyperscale cloud providers are continuously expanding AI inference computing capacity globally, creating structural growth in data center storage. The company believes this demand trend is long-term, not cyclical or short-term, and therefore maintains a positive outlook on the NAND flash industry fundamentals."

From a broader perspective, SanDisk reported stellar fiscal fourth-quarter 2026 results this week, significantly beating Wall Street expectations. The company posted revenue of $8.97 billion and non-GAAP earnings per share of $39.25. The core driver of the record revenue was a surge in AI storage infrastructure demand, which propelled data center business revenue to soar 103% quarter-over-quarter to $2.98 billion. Despite this, the stock fell 6.8% on Thursday, primarily because the company's fiscal first-quarter 2027 revenue guidance midpoint of $10.3 billion to $10.8 billion fell short of the market consensus of $10.8 billion. On Friday, SanDisk Corp. shares were trading at $1,200.00, down $58.58 (4.65%). Even with the recent summer pullback, the stock is still up nearly 430% year-to-date. The market expected the company to deliver exceptionally strong guidance to halt bearish bets, but the guidance fell short of that expectation. However, management did not signal any fundamental weakness during the earnings call. SanDisk Corp. CEO David Goeckeler stated, "Over the past two to three quarters, we have been deeply engaging with our core customers to secure long-term orders. We now have visibility into demand spanning more than four years, and we are very optimistic about the company's business outlook."

The core conclusion is that this sell-off in SanDisk Corp. appears illogical from any angle. The company is generating triple-digit revenue growth, has a massive share buyback plan in place, and possesses a clear view of demand extending well into next year.
