NEW YORK, December 31, 2025, 19:43 ET — After-hours
- Western Digital shares eased in late trading as year-end positioning weighed on high-flying storage names.
- Broader tech weakness kept pressure on the group into the final session of 2025.
- Investors are looking ahead to Western Digital’s next quarterly update for signals on data-center demand and margins.
Western Digital Corp shares fell about 2.2% to $172.27 in after-hours trading on Wednesday, after swinging between $171.28 and $177.46 earlier in the day.
The late-day dip matters because Western Digital has been a high-beta proxy for data-center spending, and year-end rebalancing can amplify moves when liquidity is thinner than usual.
It also comes as investors try to separate short-term flow-driven trading from the bigger question for 2026: whether demand for high-capacity drives used in AI-heavy data centers stays strong enough to support pricing and margins.
U.S. stocks ended the last regular session of 2025 lower, 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, pointing to profit-taking in a low-liquidity stretch; markets are closed on Thursday for New Year’s Day.

Western Digital has moved in tandem with other AI-linked storage plays as investors priced in a step-up in demand for infrastructure that stores, moves and trains on massive datasets.
That has put the stock’s day-to-day tape back in focus on the final turn of the calendar, when some investors lock in gains while others reset exposure for January.
In its most recent results, Western Digital reported fiscal first-quarter 2026 revenue of $2.82 billion and non-GAAP diluted earnings per share of $1.78. The company guided for fiscal second-quarter revenue of about $2.9 billion, plus or minus $100 million, and non-GAAP EPS of $1.88, plus or minus 15 cents, and said it expected profitability to improve as customers adopt higher-capacity drives; it also noted it completed the separation of its Flash business into Sandisk earlier in 2025.
Non-GAAP results are adjusted figures that exclude certain items companies say can obscure underlying performance, such as stock-based compensation or one-time costs.
For traders, the next key read-through will be whether the company delivers on that outlook and how management frames demand from cloud customers and large data-center buyers.
Investors will also be listening for any updated view on supply tightness in high-capacity hard drives, because that dynamic can influence pricing power and gross margin.
With U.S. markets shut on Thursday, positioning pressure may roll into Friday’s reopening, when trading typically normalizes and investors reassess year-end moves against fresh volume.
Western Digital competes most directly with Seagate in enterprise hard disk drives, while memory chipmaker Micron often trades with the same AI-infrastructure theme even though it sells different products.
By the time the stock market opens again, Western Digital’s after-hours slide will be competing with a familiar set of catalysts: macro rate expectations, data-center spending signals and the company’s next earnings update for clarity on margins and demand.
