Western Digital’s 20% Weekly Plunge Masks a Backlog That Runs Through 2028

Western Digital shares fell 21% in a week, dragged by downgrade, dilution fears, and tech sell-off, even as revenue jumps 46% and orders are sold out through 2026.

Western Digital’s share price has been battered over the past seven trading days, shedding roughly a fifth of its value even as the company’s order book remains stuffed through at least 2026. The stock closed at €514.80 on Friday, down 13.30% on the day alone, pushing the weekly loss to 21.39%. At its peak in mid-June, the shares had traded as high as €696.30 — a level that now feels distant, though the underlying demand story has rarely looked stronger.

The storage maker’s revenue hit $3.34 billion in the latest quarter, a 46% year-on-year jump, and gross margin expanded to 50.2%. The cloud segment now accounts for between 89% and 90% of total sales, and management has secured multi-year agreements that lock in capacity. Chief Financial Officer Kris Sennesael told a recent industry conference that customers are placing firm orders a full year in advance, with some contracts stretching all the way to 2032. For the calendar year 2026, every available production slot is already sold out, and the seven largest clients have snapped up the rest through 2028.

The structural drivers behind this surge are well-telegraphed. The so-called AI Memory Supercycle is fuelling demand from three distinct buckets: training artificial intelligence models, inference workloads, and physical AI applications such as robotics. Analysts project the cloud and AI storage market will expand at more than 25% annually through 2030. Western Digital, meanwhile, recently raised its quarterly dividend to $0.15 per share, a signal of confidence in cash generation.

Why, then, has the stock cratered? A confluence of technical and sentiment headwinds has overwhelmed the bullish fundamentals. The sell-off was triggered in late June when Fox Advisors downgraded the shares from “Outperform” to “Equal-Weight,” arguing that expectations for further hard-drive price increases had run ahead of reality. Shortly before that, Western Digital completed a share swap that converted over 1 million SanDisk securities into common stock, creating a short-term overhang that attracted arbitrageurs. The company is also restructuring approximately $858 million in convertible notes — a move that reduces future debt but dilutes existing shareholders through the issuance of new common equity.

Adding to the pressure, a sharp retreat in South Korean equity markets hit memory stocks across the board. Samsung and SK Hynix both fell, and because storage names rarely trade in isolation, Western Digital was caught in the downdraft. A broader rotation out of large-cap tech and into suppliers also failed to shelter the sector; instead, general tech weakness dragged down even the AI supply chain. Valuation has become a sticking point: the trailing price-to-earnings ratio stood at 44.7, leaving little room for missteps. As one market observer put it, the stock was “priced for perfection.”

Technically, the shares now sit 111% above their 200-day moving average, a stretched gap that implies substantial downside risk if sentiment turns. The relative strength index has fallen to 49.6, a neutral reading that leaves the market undecided. The 50-day line lies at €448.30, about 14.8% below the current price, offering a potential support level. Yet the annualized volatility of over 90% means any move is likely to be violent.

The pivotal factor going forward is the ramp of Western Digital’s new 40-terabyte hard drive, slated for release in the second half of the year. Profit margins depend heavily on a smooth launch; production snags or quality issues would quickly compress earnings. The next quarterly report, due in July 2026, will reveal whether the company can sustain its elevated margins and potentially raise full-year guidance. Despite the recent carnage, the fundamental reality remains that all production capacity for 2026 is already locked in via long-term contracts. The AI supercycle is real. What remains unresolved is whether the market’s current pessimism is a buying opportunity or the start of a deeper correction in a stock that had become too expensive for its own good.
