SNDK (Sandisk Corporation Common Stock), the Nasdaq ticker for Sandisk Corporation, was trading lower Thursday, August 6, after the company reported a sharp jump in quarterly revenue and profit. The results topped the estimates used by several published services, but attention quickly shifted to a next-quarter revenue outlook that was below some of the more optimistic analyst forecasts.
Key facts
- Live stock move: The stock’s August 6 move was still unfolding in late-afternoon trading. At about 3:32 p.m. EDT, Yahoo Finance market data showed SNDK near $1,286, roughly $65 below the prior close. The regular session had not closed, so there was no final closing price or full-day percentage yet. Readers searching SNDK were seeing an intraday move after the company’s earnings release, not a completed day of trading.
- Ticker: SNDK is Sandisk Corporation, not Western Digital’s stock. Sandisk completed its separation from Western Digital on February 21, 2025, and became a standalone public company. Western Digital remains a separate company with the ticker WDC.
- Latest results: Fiscal fourth-quarter 2026 revenue was $8.965 billion. GAAP (Generally Accepted Accounting Principles) diluted EPS was $43.97, while non-GAAP diluted EPS was $39.25.
- Next-quarter outlook: Fiscal Q1 2027 revenue guidance was $10.30 billion to $10.80 billion, with non-GAAP diluted EPS guidance of $44 to $46.
- Buyback authorization: Sandisk added $14 billion to its share-repurchase program, leaving $15.5 billion in remaining authorization.
What Sandisk reported
Sandisk released its fiscal fourth-quarter 2026 results on August 5 for the quarter that ended July 3. Revenue was $8.965 billion, up 51% from the previous quarter and 372% from a year earlier. Compared with the previous quarter—a comparison often called sequential growth—Sandisk said roughly one-third of the increase came from higher volume and two-thirds from higher pricing.
By end market:
- Datacenter: Revenue rose 103% from the previous quarter to $2.977 billion.
- Edge: Revenue rose 48% to $5.432 billion.
- Consumer: Revenue fell 32% to $556 million.
GAAP net income was $6.903 billion, or $43.97 per diluted share. On a non-GAAP basis, which is the company’s adjusted presentation, net income was $6.162 billion, or $39.25 per diluted share. The two earnings-per-share figures are not interchangeable: $43.97 is GAAP EPS, while $39.25 is non-GAAP EPS.
These results are preliminary and unaudited. Sandisk said the numbers reflect management’s current information and could change after final closing work, audit adjustments and completion of its Form 10-K.
The reported quarter beat the forecasts cited by both Benzinga and Proactive, though the services were not comparing it with the same numbers. Benzinga listed non-GAAP EPS of $39.25 against an estimate of $33.38 and revenue of about $8.96 billion against $8.24 billion. Proactive used higher benchmarks—about $34.96 in non-GAAP EPS and $8.48 billion in revenue—and Sandisk beat those too. In other words, the quarter beat both sets of estimates; there was no single benchmark shared by every service.
Why the outlook became the focus
For the next quarter—which Sandisk labels fiscal Q1 2027 under its fiscal calendar—the company projected revenue of $10.30 billion to $10.80 billion, a midpoint of $10.55 billion. It also forecast non-GAAP diluted EPS of $44 to $46. The company did not provide GAAP EPS guidance for the quarter.
Here is what those comparisons amount to:
- Against the roughly $10.8 billion consensus figure cited by Proactive: Sandisk’s $10.55 billion midpoint was about $250 million lower, while the top of the company’s range matched that figure.
- Against the $11.16 billion figure cited by Proactive and Yahoo Finance: The midpoint was $610 million lower, and even the $10.8 billion high end was $360 million lower.
The published benchmarks were different, so the plain takeaway is that Sandisk’s outlook was below some forecasts—not that it missed one number everyone on Wall Street had agreed on.
But the available reporting did not prove that guidance alone caused the stock’s reaction. With trading still underway, there was no definitive explanation for the short-term move.
Sandisk also expanded its buyback
Sandisk’s board approved an additional $14 billion share-repurchase program, leaving the company with $15.5 billion in remaining authorization. That is permission to buy shares, not money already spent.
Separately, Sandisk’s unaudited cash-flow statement showed that the company used $4.524 billion to repurchase common stock during the fourth quarter. The next scheduled company event is its Investor Day on August 13 at 9 a.m. EDT.
