Micron reported fiscal Q3 2026 revenue of $41.46 billion, up from $9.30 billion a year earlier, and adjusted EPS of $25.11, beating the $20.78 consensus. The earnings surprise propelled the KOSPI 5% higher at the open and sent Micron shares up about 15% after hours.
Micron delivered fiscal Q3 revenue of $41.46 billion, more than quadrupling the $9.30 billion from the same quarter last year, and posted adjusted EPS of $25.11 versus the $20.78 analyst consensus. These results underscore a significant demand rebound in memory markets and the company’s improved pricing power.
The unexpected earnings beat triggered a 5% surge in the KOSPI at the open, pushing the index back above 8,900 and activating a five-minute buy-side sidecar to curb program trading. Micron shares rallied roughly 15% in after-hours trading, while SK Hynix and Samsung Electronics also climbed in early Asian sessions.
Domestic retail investors net bought about 490 billion won and institutions added 100 billion won following the report, even as foreign investors sold 600 billion won. Contributing factors included a drop in oil prices and the U.S. 10-year Treasury yield falling below 4.4%, which bolstered risk appetite across semiconductor names.
