Company Overview

Founded in 1970 by a Motorola employee, Western Digital (NASDAQ: WDC) is a leading producer of hard disk drives, SSDs and flash memory.

Sales Growth

Reviewing a company’s long-term sales performance reveals insights into its quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Over the last five years, Western Digital’s demand was weak and its revenue declined by 7.9% per year. This was below our standards and is a sign of poor business quality. Semiconductors are a cyclical industry, and long-term investors should be prepared for periods of high growth followed by periods of revenue contractions.

We at StockStory place the most emphasis on long-term growth, but within semiconductors, a half-decade historical view may miss new demand cycles or industry trends like AI. Western Digital’s recent performance shows its demand remained suppressed as its revenue has declined by 13.2% annually over the last two years.

This quarter, Western Digital’s revenue fell by 33.6% year on year to $2.29 billion but beat Wall Street’s estimates by 1.9%. Despite the beat, the drop in sales could mean that the current downcycle is deepening. Company management is currently guiding for a 34.9% year-on-year decline in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to decline by 11.8% over the next 12 months, similar to its two-year rate. While this projection is better than its two-year trend, it's hard to get excited about a company that is struggling with demand.

Software is eating the world and there is virtually no industry left that has been untouched by it. That drives increasing demand for tools helping software developers do their jobs, whether it be monitoring critical cloud infrastructure, integrating audio and video functionality, or ensuring smooth content streaming. .

Product Demand & Outstanding Inventory

Days Inventory Outstanding (DIO) is an important metric for chipmakers, as it reflects a business’ capital intensity and the cyclical nature of semiconductor supply and demand. In a tight supply environment, inventories tend to be stable, allowing chipmakers to exert pricing power. Steadily increasing DIO can be a warning sign that demand is weak, and if inventories continue to rise, the company may have to downsize production.

This quarter, Western Digital’s DIO came in at 86, which is 26 days below its five-year average. At the moment, these numbers show no indication of an excessive inventory buildup.
