Sandisk is trading 10.12% down now at $1237.99 after investors rejected otherwise strong fiscal fourth-quarter results over first-quarter 2027 guidance that fell below some Wall Street expectations.

  • Fiscal fourth-quarter revenue surged 372% to $8.97 billion and adjusted EPS reached $39.25, beating estimates.
  • First-quarter 2027 revenue guidance was $10.3–$10.8 billion. The selloff also reflects lofty AI-storage expectations and pressure across storage-chip stocks after Western Digital issued similarly disappointing guidance.
