Hey there, bargain hunter. Western Digital posted $4.64 per share, raised its dividend, guided December EPS to as much as $6.00, and still fell 6.43% in the session and another 6.5% after hours. WDC was sitting near $331 by the close of extended trading, down more than 55% from its June peak of $799.87. The numbers were not the problem.
Scoreboard
Q1 FY2027 revenue hit $4.381 billion, up 55% year over year and about $240 million above consensus. Non-GAAP EPS came in at $4.64, a 161% increase and roughly a $0.5 beat. Free cash flow reached $1.38 billion. Q2 guidance: $5.0 to $5.2 billion in revenue versus a $4.57 billion estimate, and EPS of $5.60 to $6.00 against a $4.79 consensus. The midpoint EPS beat was about a dollar.
What Actually Happened
The selloff started before earnings. China’s ChangXin Memory Technologies (CXMT) had highlighted plans to ramp DRAM output, rattling the broader memory group for weeks. SanDisk fell roughly 8% and Micron around 6% on October 22 alone.
Western Digital does not make DRAM. Following its February 2025 spin-off of the NAND business as SanDisk, WDC is a pure-play HDD company. Cloud revenue in Q1 was $3.9 billion, 88% of total revenue. The CXMT threat runs through sentiment, not product competition.
The Valuation Question
Annualize the Q2 EPS guidance midpoint of $5.80 and the forward run rate lands near $23.20 per share. At the October 22 close of $354.19, that is 15.3x. At the after-hours price near $331, it falls to 14.3x. The hardware sector’s median forward multiple sits around 18x; WDC’s own 10-year trailing median is above 20x.
The market is pricing this as a cyclical peak. The company is arguing secular demand. Both have merit. Non-GAAP operating margin hit 49.1%, average price per terabyte rose 28% year over year, and non-GAAP gross margin is guided to about 60%-to-61% for December. HDD cycles have punished believers before, and near-term CapEx is running modestly above the long-term 4%-to-6%-of-revenue target as WDC invests in heads and media technology.
Bull / Base / Bear
Bull: AI storage demand is durable, gross margin reaches 60%-plus in December, and the stock re-rates toward 18x forward earnings, implying a price above $415.
Base: Growth moderates as comparisons toughen. Margins hold in the high-50s. WDC drifts toward $370 to $390 as fear fades.
Bear: DRAM oversupply fears spill further into hardware, HDD pricing softens, and the AI capex cycle stalls. At 12x trough, WDC revisits the low $200s.
The bull case rests on cloud capex remaining durable. AWS expanding operating margins while absorbing the largest infrastructure buildout in Amazon’s history suggests hyperscaler storage demand is not yet near a ceiling.
Action Plan and Checklist
Conservative accounts: watchlist, not buy list. Wait for December-quarter gross margin to confirm about 60%-to-61%. That result arrives in late January.
- Does Q2 gross margin land around 60%-61%?
- Does CXMT’s DRAM ramp translate into meaningful exportable volume by year-end 2026?
- Does exabyte growth reaccelerate past 22% toward the 25% long-term target?
- Does cost per terabyte return to the 10%-annual-decline track?
- Is CapEx contained below 8% of revenue?
Bottom Line
WDC is trading at roughly 15x an accelerating earnings run rate because the market is assigning cyclical fear to a business running 49% operating margins with December guidance sitting about 21% above analyst estimates. If the gross margin guide holds and CXMT’s timeline slips, that discount closes fast. If HDD pricing cracks first, the bear case is real. The December quarter settles it.
