Three-month figures from DART consolidated statements. Q4 is the annual figure less the nine-month cumulative. EPS is net income over today's share count, so buybacks and issuance move earlier quarters. YoY compares with the same quarter a year earlier and is blank when that quarter was a loss.

006400 Next Report

The latest quarter on file is 2026 Q2. The next one, the Q3 2026 report covering the period to Sep 30, 2026, is due on DART by Nov 14, 2026 — Korean issuers must file quarterly and half-year reports within 45 days of period end and the annual report within 90 days.

Large issuers usually publish preliminary consolidated figures (잠정실적, a fair-disclosure filing with revenue and operating profit only) in the first weeks after the period ends, ahead of the full report. kstock does not know a company's chosen release date; when the preliminary filing arrives it appears under Filings and on this page.

How Korean earnings differ from US earnings

  • No quarterly guidance culture. Most KRX companies give no EPS or revenue guidance; the preliminary filing is the first number the market sees, and there is no consensus beat/miss ritual built around it.
  • Preliminary first, then the report. The 잠정실적 filing carries revenue and operating profit; net income and the balance sheet come with the full report weeks later.
  • Consolidated is the headline. Korean companies report consolidated (K-IFRS) and separate (parent-only) figures; kstock uses consolidated unless the page says otherwise.
  • Fiscal years end in December for almost every listed company, so Q4 is derived: the annual figure less the nine-month cumulative.
