NEW YORK, December 30, 2025, 17:33 ET — After-hours
- Sandisk shares were down 1.6% at $240.22 in after-hours trading.
- The company set its fiscal second-quarter earnings call for Jan. 29, 2026. 1
- Micron and Western Digital were also lower, while the semiconductor ETF was little changed.
Sandisk Corp (SNDK) slipped in after-hours trading on Tuesday after the company set Jan. 29 for its next earnings report. Shares were last down 1.6% at $240.22. 1
The calendar update lands as Sandisk heads into the final two sessions of the year with a stock that has been among 2025’s biggest S&P 500 gainers. That has kept traders on alert for outsized swings around even routine company updates. 2
Investors use Sandisk’s results as a read on demand and pricing for NAND flash — the memory used in storage devices such as solid-state drives (SSDs). The company has highlighted data-center demand as a key driver, alongside consumer and client markets. 3
Sandisk said the fiscal second-quarter earnings conference call is scheduled for Thursday, Jan. 29, 2026, at 1:30 p.m. Pacific time (4:30 p.m. ET), with a live webcast and replay available on its investor site. 1
During Tuesday’s session, the stock traded between $236.64 and $247.26, with roughly 5.7 million shares changing hands. The S&P 500 and Nasdaq were down 0.14% and 0.24%, respectively. 3
Peer moves were subdued in late trade, with Micron down 0.6% and Western Digital off about 2.0%, while the iShares Semiconductor ETF slipped 0.1%.
Sandisk, based in Milpitas, California, sells NAND-flash storage products including SSDs, removable cards and USB drives. It became a standalone, publicly traded company after separating from Western Digital in February. 3
The stock’s sharp 2025 run — up about 594% as of Kiplinger’s latest tally — has also made it sensitive to profit-taking and year-end portfolio rebalancing. 2
Sandisk last reported quarterly results in November, when it posted first-quarter revenue of $2.31 billion and non-GAAP (adjusted) earnings of $1.22 per share. It forecast fiscal second-quarter revenue of $2.55 billion to $2.65 billion and non-GAAP earnings of $3.00 to $3.40 per share. 4
“Customers are turning to Sandisk for our leading technology and products, which are exceptionally well positioned at a time when demand is strengthening,” CEO David Goeckeler said in that release. 4
For the Jan. 29 report, investors will focus on data-center momentum, including progress with hyperscalers — large cloud providers — and on the ramp of BiCS8, Sandisk’s latest generation 3D flash technology. BiCS8 accounted for 15% of total bits shipped in the first quarter, the company said. 4
Traders are also watching near-term technical levels after Tuesday’s swing, with support near the session low of $236.64 and resistance around the $247.26 high.
