Western Digital (WDC) Stock Price Retreats Despite AI Fueled Margin Strength

Western Digital walked into this earnings season with a reputation as a high growth, AI leveraged storage leader trading on a modest 16.1x trailing P/E. Yet the stock dropped about 4% today and is down around 21% over the past month, even as the latest quarter delivered US$3.7b in revenue and very high net profit margins on a trailing basis.

The gap between that sharp share price pullback and the strength of the reported profitability is now the core question for investors. The full earnings story rests on whether those margins and cash generation can hold in a storage cycle this volatile.

Love Western Digital's strong reported margins and AI angle but worried about how volatile storage cycles can hit cash generation next? Take a look at our hand picked list of solid balance sheet and fundamentals stocks (49 results).

Western Digital’s AI HDD Story Meets Hard Milestones

The bullish story around Western Digital is that high capacity HDDs sit at the heart of AI and cloud storage and that this will support strong margins and more predictable earnings. The latest quarter goes a long way toward proving that out. Revenue of US$3.75b with non GAAP gross margin above 50% aligns with the claim that tight HDD supply and a richer mix are supporting high profitability. Exabyte shipments grew 22% year on year to 231 EB, which backs up the idea that hyperscale and AI data growth is flowing directly into capacity demand.

Crucially, Western Digital is not just talking about a roadmap; it is shipping it. Next generation 40 TB ePMR drives are already in market, and management is ramping UltraSMR. Early work on a 44 TB HAMR platform for 2027 plus multiyear contracts out to 2031 show execution against both technology and customer visibility milestones.

Western Digital: Strong Print, But Bears See Peak Signals

The bearish view on Western Digital is that HDD demand is structurally at risk and current AI strength could mark a late cycle peak rather than a new base. This quarter’s 54.4% gross margin and US$3.5b full year free cash flow clearly do not support an imminent collapse in profitability. However, the reaction around the Q1 FY 2027 guide validates part of the concern that margins may be near a high point. Management guided gross margin to 55 to 56% with continued growth, yet the stock fell about 11 to 15% on the day and is down roughly 21% over 30 days. That reset suggests expectations around AI storage pricing and peak economics had run ahead of earnings. Multi year HDD contracts out to 2031 and sold out capacity argue against a rapid secular HDD decline, but the market is treating this print as a possible high watermark rather than a fresh leg higher.

After a quarter this strong, yet marked by volatile trading, insider selling and high non cash earnings, it is worth asking whether recent concerns around Western Digital are isolated or hinting at deeper structural issues.
