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.
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.
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. Reuters
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.
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.
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.
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.
