Key Takeaways
Western Digital Corp. (NASDAQ: WDC) reported third-quarter revenue of $3.34 billion, a 45% year-over-year increase that beat analyst expectations, but its stock fell more than 5% in after-hours trading as investors balked at its forward guidance.
The post-earnings drop comes after the stock’s massive rally created a high-risk, high-reward setup where performance needed to confirm the AI storage boom is accelerating. Ahead of the report, Zacks Investment Research noted that "much of this optimism is already reflected in the valuation, meaning upcoming earnings must live up to expectations."
The company's performance for the quarter that ended March 31 was strong, though it did not disclose earnings-per-share data in its initial release. The focus quickly shifted to the company's outlook for the fourth quarter.
For its fourth quarter, Western Digital projected an adjusted gross margin between 51% and 52%, a significant step up from the 47% to 48% guided for the third quarter. The company also forecast operating expenses in the range of $385 million to $395 million.
While the margin expansion is notable, the negative stock reaction suggests investors had priced in an even more aggressive outlook. The sentiment highlights the immense pressure on companies at the center of the artificial intelligence infrastructure boom to continuously deliver blowout results.
The rally in Western Digital's stock, which has seen it gain 888.6% over the past year and vastly outperform peers like Seagate Technology (NASDAQ: STX) and Micron Technology (NASDAQ: MU), has been fueled by surging demand for its high-capacity hard disk drives used in data centers. As generative AI becomes central to business, the need for mass-scale, cost-effective storage has exploded, with AI and cloud demand now accounting for roughly 90% of the company's revenue, according to analyst reports.
This demand allowed the company to secure firm purchase orders through 2026. However, it also pushed the company's valuation to a forward price-to-earnings ratio of over 31, nearly double the industry average of 16.8, setting the stage for a sharp correction on any perceived weakness.
The guidance, while strong on its face, was not enough to satisfy a market that had priced in perfection after a nearly 900% run-up. Investors will watch the upcoming earnings call and competitor reports from Seagate and Micron to gauge if this is a company-specific reaction or a broader cooling of sentiment in the AI storage sector.
