Sejin Heavy Industries세진중공업

Sejin Heavy Industries has strong recent profitability, but its share price has fallen sharply over the past year.

Sejin Heavy Industries makes deck houses and hull parts for ships, plus plant equipment for offshore energy projects, which recorded no revenue in the latest period. Trailing twelve-month results to H1 2026 show revenue of ₩387B, operating income of ₩81B and net income of ₩64B. The shares closed at ₩7,480 on 2026-10-23, down about 67% over one year and near the 52-week low of ₩7,230.

What stands out

• Trailing operating margin is 20.9% and net margin is 16.6%, well above the 2024 operating margin of 10.2%.
• Free cash flow is ₩54B against borrowings of ₩251B and cash of ₩43B, so debt is significant relative to cash.
• The data's DCF model gives a base value of ₩4,710 and a bull value of ₩11,916, both below or near the current price in the base case; the model is an estimate, not a forecast.
• Valuation looks low on earnings, with a P/E of 6.6 and dividend yield of 3%, but the share price has fallen far faster than profits.
• Foreign ownership rose from 2.4% to 2.9% over 60 days, while retail investors were net sellers of about ₩2.7B over 20 days.

What to watch

• The Q3 2026 quarterly report, expected after the H1 2026 half-year report filed on 2026-08-13, will show whether profitability holds.
• Filings noted a 5%+ holding report on 2026-07-23 and a change in the largest shareholder's holdings on 2026-04-06; further holding changes could matter.
• The data names no recent news headlines, and the plant segment has had no revenue in the reported period, so that business's outlook is unclear.
