US-Korea Earnings Season, Reports Cluster Right After Quarter End

TL;DR

• US and Korea earnings seasons tend to concentrate immediately after quarter end, with differences in market practices and disclosure rules.
• Before making any investment decision, confirm the latest report dates and conference call schedules via filings, company IR, and broker research.

1. Basic structure of earnings season

• Quarterly results are typically divided into Q1, Q2, Q3, and annual (including Q4). After the quarter close, companies compile results and follow disclosure procedures.
• Both the US and Korea show clustering of releases after quarter end. Timing varies with filing deadlines, internal company schedules, and industry characteristics.

2. US disclosure practices

• In the US, major listed companies commonly report results within weeks after quarter end. Large and mid cap earnings often cluster around mid to late next month after quarter close.
• Investors check quarterly conference calls or webcasts, analyst reports, and SEC filings (10-Q, 10-K, etc.). Confirm current rules and deadlines with broker research or disclosure sites.

3. Korea disclosure practices

• In Korea, companies publish quarterly, semiannual, and annual results via public filings (e.g., Financial Supervisory Service electronic disclosure). Quarterly releases also tend to cluster right after quarter end, while annual results often align with closing and shareholder meeting schedules.
• Timing varies by large caps, small caps, and IPO timing. Check the latest rules for specific deadlines and tax or regulatory matters.

5. How to use a calendar in practice

1. Mark expected concentrated release windows based on quarter close dates on your calendar.
2. Set IR page and filing alerts for companies you follow to get real time disclosure updates.
3. Check research updates and conference call schedules around major reports.
4. Review historical seasonality and industry-specific quarterly patterns to prepare.
