Why Is Western Digital Stock Sinking Thursday?
Western Digital (WDC) shares fell about 14.9% premarket after fiscal Q4 results beat estimates but its outlook disappointed. Adjusted EPS rose to $3.56 vs $3.29 consensus, revenue rose 44% to $3.75B vs $3.69B. Q1 FY2027 revenue guidance is ~$4.1B and adjusted EPS $3.85-$4.15. Peers Seagate (STX) and SanDisk (SNDK) also declined.

The 30-second read
Why it matters
Traders likely focus on the gap between consensus and management’s Q1 revenue, gross margin, and adjusted EPS ranges, and on whether AI-driven nearline demand remains as strong as priced.
Market read
WDC’s guidance-driven repricing is the immediate catalyst, with sector read-across to AI storage and HDD names.
What to watch
The article highlights product ramp milestones (44TB HAMR, 40TB EPMR, Ultra SMR expansion) and cloud revenue growth, which could offset the near-term outlook disappointment if demand visibility improves.
Background
The piece frames WDC’s selloff as a guidance disappointment despite strong fiscal Q4 operating and financial metrics.
Ticker impact
Western Digital reported fiscal Q4 earnings and revenue beats, but its Q1 outlook and guidance range came in below elevated expectations, sending shares down premarket.
Bearish bias for the next session as traders reprice AI memory and HDD demand expectations around the guided revenue and earnings ranges.
The article attributes the selloff to the outlook falling short, and provides specific Q1 revenue, gross margin, and adjusted EPS guidance ranges versus consensus.
Market effects
AI memory and storage stocks pulled back alongside WDC, suggesting read-across pressure on HDD/nearline demand expectations.
Primarily US-listed storage complex reaction; no specific regional spillover cited.
Global hyperscale storage demand narrative is reinforced, but near-term sentiment turns cautious due to guidance.
Counterpoint
Despite the stock drop, WDC’s gross margin expansion, free cash flow, and shipment growth indicate fundamentals may be stronger than the market’s expectations.
