Western Digital stock fell 11% in extended trading on August 5 despite the storage maker reporting a fourth-quarter earnings beat and upbeat guidance, reflecting investor concern over elevated expectations in the AI-driven memory sector.
The company reported adjusted earnings per share of $3.56 for fiscal Q4, surpassing the consensus estimate of $3.29, while revenue reached $3.75 billion, up 44% year-over-year and ahead of Wall Street’s forecast of $3.70 billion. The results underscored strong demand for data-center storage tied to artificial-intelligence infrastructure buildout.
Yet guidance disappointed relative to market hopes. Western Digital forecast first-quarter revenue of $4.1 billion, plus or minus $100 million, and adjusted EPS of $3.85 to $4.15—both above analyst expectations of $4.06 billion and $3.84, respectively. The company projected gross margins of 55% to 56%, however, falling short of what rival Seagate Technology signaled in its recent earnings. Barron’s reported that Western Digital attributed the margin gap partly to quarter-to-quarter pricing fluctuations, which should ease as customers sign new long-term agreements at higher rates.
The selloff illustrates a broader 2026 pattern in which technology stocks have tumbled after reporting earnings beats, as investors demand not just strong results but also exceptional forward guidance. Intel stock fell nearly 8% in late July despite a big earnings beat, while Figma dropped 16% on August 6 following a Q2 earnings beat overshadowed by steep artificial-intelligence investment costs. Reddit fell 10% in late July despite a strong earnings report, and Apple declined following a beat as investors weighed guidance concerns.
Western Digital’s stock had surged 176% year to date before the earnings print, raising the bar for what would satisfy the market. The company’s position as a critical supplier of hard drives and storage for AI data centers had fueled that rally, but the modestly conservative guidance suggested the boom may be maturing. Gross margin compression—a sign of potential pricing pressure—particularly concerned investors already wary of a slowdown in AI infrastructure spending after months of euphoric gains.
The reaction underscores a shift in market sentiment: earnings beats alone no longer guarantee stock gains when they arrive after massive year-to-date rallies. Investors are now scrutinizing guidance, margins, and signs of demand normalization, especially in sectors tied to the AI supercycle. For Western Digital, the strong operational performance proved insufficient to overcome the weight of sky-high expectations.
