Western Digital (NASDAQ: WDC) saw its shares plunge as much as 10.8% in after-hours trading on Wednesday, extending a 5.4% decline during the regular session, even as the company reported quarterly results that topped Wall Street forecasts. The sharp selloff underscores the challenge of meeting sky-high expectations after a more than 190% rally in 2026.
Record profitability, but investors wanted more
The company posted adjusted earnings of $3.56 per share, up from $1.70 a year earlier and above the analyst consensus of $3.31. Revenue surged 44% year-over-year to $3.75 billion, edging past the $3.70 billion expected. Non-GAAP gross margin expanded to 54.4% from 41.3%, while operating cash flow reached $1.39 billion and free cash flow hit $1.28 billion.
These figures reflect robust demand for hard-disk drives from hyperscale data centers and AI workloads, with tight supply and favorable pricing boosting profitability. CEO Irving Tan noted that the company enters fiscal 2027 with greater visibility and confidence in demand, as HDDs remain a cost-effective solution for storing the massive datasets generated by AI training and inference.
However, the market's reaction suggests that investors are no longer satisfied with merely beating estimates. After such a dramatic run-up, the stock needed a larger surprise to justify its valuation. Analysts described the quarter as excellent but said the decline highlighted the elevated bar facing suppliers to the AI boom.
Guidance beats, but Seagate comparison stings
Western Digital guided first-quarter revenue to $4.0-$4.2 billion, versus the $4.04 billion consensus, and adjusted earnings of $3.85-$4.15 per share, above the $3.76 estimate. While the midpoints of both ranges exceeded expectations, the beats were modest. The company's outlook appeared more conservative than the forecast recently issued by rival Seagate, according to Investor's Business Daily.
Morgan Stanley analyst Erik Woodring, who had been bullish ahead of the report, argued that AI inferencing, cloud growth, and limited supply could sustain strong HDD demand for years. Yet the market's reaction indicates that investors are demanding more aggressive guidance, especially when compared to Seagate's more robust projections.
AI storage thesis intact, but execution is key
The results did not undermine the long-term storage story. Western Digital and Seagate dominate a concentrated HDD market, and hyperscalers need cost-effective capacity for expanding data sets. However, the company must now prove it can continue raising prices, expanding margins, and converting demand into cash without falling behind Seagate's execution.
Wedbush analyst Matt Bryson had previously flagged similar concerns after Western Digital's last report, noting that management's forecast was less robust than hoped, particularly regarding margin expansion. Wednesday's selloff suggests that concern is recurring: the company is delivering strong results, but the market repeatedly seeks more incremental upside.
For context, other tech names have faced similar dynamics. For instance, AMD's stock dropped 9% despite a record quarter due to a flat margin outlook, and NYT shares slid 12% on subscriber growth misses. The pattern highlights how elevated expectations can turn solid results into negative reactions.
Investors will now watch whether Western Digital can deliver the kind of upside that justifies its valuation, or if the stock's recent surge has priced in perfection. The AI-storage thesis remains intact, but the market's patience for modest beats may be wearing thin.
