What the filing actually says.

AI · forensic preset

The filings present two different stories. Operating results show a real recovery: cloud demand and pricing lifted nine-month operating income to $2,890 million, from $1,654 million a year earlier. Reported net income, however, leans heavily on the Sandisk retained-interest gain, so readers may want to look at the operating line and the non-operating items separately. The Beneish M-Score is -3.038, below the -1.78 threshold, so it is not in the elevated manipulation-risk zone. That is a screening result, not proof that the numbers are accurate. The Altman Z-Score is 2.16, which falls in the grey zone between 1.10 and 2.60, meaning it is neither clearly safe nor distressed. The Piotroski F-Score is 6 of 9 computable signals. Operating cash flow of $1.69 billion against net income of $1.89 billion gives a ratio of 0.90 for fiscal 2025. Fiscal 2025 revenue of $9.52 billion was down 26.8% from $13 billion, but the Separation from Sandisk, completed February 21, 2025, changes the comparability of prior-year figures, so the annual decline should be read with that in mind. Balance sheet changes are substantial: long-term debt fell from $5.68 billion to $2.48 billion, and equity fell from $10.82 billion to $5.31 billion in fiscal 2025. Those moves reflect the Bridge Loan, Senior Note redemptions, Term Loan A-3 exchange, and conversion of preferred shares into 7 million common shares. Readers may want to look at how much of future earnings depends on cloud demand sustaining its pricing and on the remaining Sandisk share monetization.

Catalyst.In the quarter ended April 3, 2026, net revenue was $3,337 million, up 45% from $2,294 million a year earlier, driven by a 34% increase in exabytes sold and a 9% increase in average selling price per exabyte. Cloud, which management says represents 89% of total revenue, grew 48% to $2,972 million. Management attributes this to AI adoption, hybrid data growth, and accelerated demand for high-capacity drives. It notes longer production lead times and that customers are partnering earlier and extending the duration of their commercial arrangements. Quarterly operating income rose to $1,190 million from $760 million. For the nine months, revenue was $9,172 million, up 33%.

Hidden risk.Nine-month net income from continuing operations was $6,229 million, while operating income was $2,890 million. The gap is largely a non-operating item: a $4,448 million gain on the retained interest in Sandisk. Costs of $545 million tied to the debt-for-equity exchange also appear below operating income. As of April 3, 2026, the company held 1.7 million Sandisk shares and expects to monetize them by the end of 2026, so this gain source is finite and depends on Sandisk's value. The 10-K risk factors also flag tariffs, sole-source suppliers, and geographic concentration in California and Asia as ongoing exposures.

What traders are betting.

The scores above come from what WDC reports to the SEC. These readings come from how traders are positioned in its shares. They change quickly, they can be wrong, and they are not part of the verdict.

What it tells us

Few traders are betting against WDC. Levels this low are common for large, widely held companies.

Little changed since the Aug 31 report (−8.0%).

At normal trading volume, short sellers would need about 2.8 days to buy back every borrowed share.

How investors use it

  • Squeeze watching. Some aggressive traders seek out heavily shorted stocks, betting that good news will force short sellers to buy back shares and push the price higher.
  • Hedging. Funds short one company to offset risk in another, often owning a stronger business and shorting a weaker one in the same industry.
  • Timing. Chart-based traders pair rising short interest with price patterns, such as a break below a level where buyers used to step in, to decide when to enter or exit.
  • Warning sign. Some owners treat a sharp rise in short interest as a red flag and respond by tightening stop-loss orders or holding smaller positions.
