NEW YORK, December 31, 2025, 17:55 ET — After-hours
- Sandisk shares were down about 1.2% in after-hours trade.
- The company set Jan. 29 for its fiscal second-quarter results and conference call.
- Traders are sizing up year-end profit-taking after Sandisk’s outsized 2025 run.
Sandisk Corp (SNDK) shares were down 1.2% at $237.38 in after-hours trading on Wednesday, after U.S. markets closed at 4 p.m. ET. The stock traded between $235.54 and $241.69 during the regular session.
The flash-memory maker has been one of 2025’s biggest winners, climbing about 559% and riding AI-driven demand for data storage and memory chips, Barron’s reported. Sandisk was spun off from Western Digital in February and joined the S&P 500 late in the year. 1
That backdrop raises the stakes for Sandisk’s next earnings report, due Jan. 29. Investors are looking for signs that NAND flash — the memory chips used in solid-state drives — can hold pricing momentum as the industry heads into 2026.
Sandisk said on Tuesday it will host a fiscal second-quarter conference call at 1:30 p.m. Pacific time, with a webcast and replay available online. 2
The broader market ended 2025 on a softer note, with the S&P 500 down 0.74% and the Nasdaq off 0.76%, Reuters reported. “It’s perfectly fine in any bull market to have moments of cost,” said Giuseppe Sette, co-founder and president of Reflexivity, citing profit-taking when liquidity is low. 3
Peers also slipped in after-hours trading, with Western Digital (WDC) down 2.2%, Seagate Technology (STX) off 1.7% and Micron Technology (MU) down 2.5%.
Sandisk began trading on Nasdaq under ticker SNDK after completing its separation from Western Digital in February, the company said. 4
S&P Dow Jones Indices said in November that Sandisk would enter the S&P 500 and replace Interpublic Group, effective before trading opened on Nov. 28. 5
In its most recent results release, Sandisk reported first-quarter revenue of $2.31 billion and forecast fiscal second-quarter revenue of $2.55 billion to $2.65 billion. It guided for non-GAAP diluted earnings per share of $3.00 to $3.40, and said datacenter revenue rose 26% sequentially; non-GAAP excludes certain items such as stock-based compensation. The company said its BiCS8 technology accounted for 15% of total bits shipped and is expected to reach the majority of bit production by the end of fiscal 2026. 6
On Jan. 29, focus will fall on margins and management’s take on inventories and supply discipline, two swing factors in the cyclical memory market. Investors will also look for updates on cloud customers — often called hyperscalers, the largest cloud operators — as they qualify new enterprise storage for AI-heavy workloads.
U.S. equity markets are closed Thursday for New Year’s Day and reopen on Jan. 2, a calendar that can thin trading and exaggerate late-day moves. For Sandisk, the scheduled event risk remains the Jan. 29 report and call. 7
