WDC Fell 11.6% in the Past Month. Is the Weakness an Opportunity?
Western Digital (WDC) shares fell 11.6% in the past month despite strong financial performance. Q4 revenue rose 44% YoY to $3.75B, and non-GAAP EPS increased 109% to $3.56. Cloud demand drove 89% of revenue, with management expecting over 25% exabyte demand growth. WDC's gross margin expanded to 54.4%, and it expects Q1 FY2027 revenue of about $4.1B. Risks include customer concentration and a premium valuation at 22.9X forward earnings.
