Sandisk is trading at $1285.01, down 3.39% in after-hours trading as memory-chip shares face pressure from Samsung and Intel disappointments and a broader technology sell-off. - Fiscal Q1 revenue was $11.03 billion and non-GAAP EPS was $49.51; both beat expectations. - Sandisk forecast Q2 revenue of $12.2–$12.6 billion, also above expectations, so results and guidance do not clearly explain the decline.
