Why it moved

This is industry reporting, not a confirmed direct HBM-order disclosure.
Contract value, duration and minimum volumes were not verified.
Disclosed performance
The August 13 standalone preliminary disclosure reported Q2 revenue of KRW 30.185 billion (+64.5%), operating profit of KRW 795 million and net profit of KRW 127 million.
First-half revenue was KRW 52.370 billion (+59.0%), but operating loss was KRW 1.260 billion and net loss KRW 2.145 billion.

Preliminary figures may change upon external review.
Risks to check
Recurring volumes, margins, customer concentration and fixed costs matter.
The Elec’s KRW 110 billion-plus annual revenue is an industry forecast, not a reported result.
A September 21 concentrated-account trading caution was observed, not proof of a current investment-warning designation.
Post-rally volatility remains a risk.
Review-only, not an investment recommendation.
The historical-data discrepancy is unexplained, but today’s close and change were independently matched with Hankyung.
