What is the difference between annual, half-year, and quarterly reports in Korea?

An annual report is a comprehensive filing with audited financials, business overview, and risk factors — analogous to the US 10-K. A half-year (interim) report covers H1 results. Quarterly reports cover Q1 or Q3 — analogous to the US 10-Q but Korea publishes only two quarterly reports per year (with the half-year report covering Q2). SignalX provides AI-generated English summaries for all three filing types for YC.
