On August 6, SanDisk Corp. declined 7.55% overnight, trading at $1,248.00/share, with turnover of $1.4111 million. The sell-off was triggered by the company's below-consensus Q1 FY2027 revenue guidance despite a blowout Q4 FY2026 earnings report.

SanDisk reported Q4 FY2026 revenue of $8.97 billion, surging 372% year-over-year and exceeding the market estimate of approximately $8.39 billion. Adjusted EPS came in at $39.25, beating the consensus of $34.45 by nearly 14%. GAAP net income reached $6.9 billion, swinging from a loss in the year-ago period. However, the company guided Q1 FY2027 revenue to $10.3-$10.8 billion, with a midpoint of $10.55 billion, falling short of the Street's $10.8 billion expectation. Adjusted EPS guidance of $44-$46 also landed slightly below the consensus of $45.58.

Simultaneously, the board approved a new $14 billion share repurchase program, bringing total remaining authorization to $15.5 billion. Nonetheless, the softer forward outlook failed to offset investor concerns over decelerating growth momentum, as the AI storage leader faces elevated expectations following its massive revenue ramp.
