Korea Petro Chemical IND: Profits Recover From Losses, but Shares Fall Sharply and a Production Halt Is Filed

Thesis

The data supports a recovery story in the numbers: operating income moved from a loss of ₩59.9B in 2024 to ₩52.7B in 2025 and ₩136.8B over the trailing twelve months to H1 2026. Revenue is also higher, at ₩3.56T. The share price has not reflected this, falling 13.5% in one month, 11.3% in three months and 29.4% in one year, and it sits close to the 52-week low of ₩79,300 versus a high of ₩202,500. The data does not explain why. It also does not say what the production halt covers, how long it lasts, or its financial impact, so any link between that filing and the price is not established. Margins remain thin at 3.8% operating and 2.1% net, well below the 7.1% operating margin of 2021.

Business overview

Financial analysis

These figures come from filed financial statements. Trailing twelve-month revenue to H1 2026 is ₩3.56T, operating income ₩136.8B, net income ₩73.7B, operating margin 3.8%, net margin 2.1% and ROE 4.0%. For 2025, revenue grew 19.6% to ₩3.35T, operating margin was 1.6%, net income ₩31.7B and ROE 1.7%. The 2022 loss was the deepest, with an operating loss of ₩214.6B (margin -9.7%). The balance sheet looks conservative: liabilities to equity is 35.6%, cash is ₩302.7B against borrowings of ₩157.7B, and free cash flow is ₩102.4B.

Valuation

The stock trades at a P/E of 7.5, P/B of 0.3, P/S of 0.2 and a dividend yield of 1.5%. Enterprise value is ₩410.1B; EV/EBITDA is not available. Its own year-end P/B was 0.3 to 0.6 across 2021 to 2025, so the current 0.3 is at the low end of that range. Year-end P/E was 7.9 in 2021 and 29.7 in 2025, reflecting very different earnings levels. Among the listed peers, P/B is 0.5 for LG Chem, 0.7 for Hanwha Solutions, 0.4 for Hanwha, 2.3 for SKC and 0.3 for KCC; P/E is available only for Hanwha (6.8) and KCC (0.9). The valuation model estimate (fair value) is not available for this company, so no comparison with the share price can be made.

Catalysts

• The Production Halt filing on 2026-10-06 could matter once its scope, duration and cost become clear, though the data gives no details.
• The next earnings releases will show whether the H1 2026 trailing recovery in operating income to ₩136.8B continues.
• Insider shareholding reports (2026-10-06, 2026-09-17) and changes in the largest shareholder's holdings (2026-09-11, 2026-08-14) show ongoing ownership activity.
• A 5%+ holding report was filed on 2026-10-02, following another on 2026-07-01, which points to changes among large holders.
• Retail investors were net buyers of ₩6.4B over 20 days, which is a flow pattern worth watching against foreign selling.

Risks

• Margins are thin at 3.8% operating, so modest swings in conditions could move profit quickly, as the 2022 to 2024 losses show.
• The Production Halt filing carries unquantified operational and earnings risk because the data gives no detail.
• Foreign ownership fell from 13.6% to 9.7% over 60 days, and foreigners were net sellers of ₩4.9B over 20 days.
• The share price is near its 52-week low and down 29.4% over a year, showing weak market sentiment.
• ROE of 4.0% is low, and the 2025 P/E of 29.7 shows how much earnings have varied from year to year.

Closing view

The filed numbers show a clear improvement from three loss-making years, with solid cash relative to borrowings and positive free cash flow. The market, however, has moved the other way: the price is down sharply, foreign holdings are shrinking, and a production halt was filed in early October with no detail in the data. Low multiples such as a P/B of 0.3 sit alongside low returns and thin margins, and no model estimate is available. The evidence is mixed and depends on details not in the data, mainly the halt and the durability of the profit recovery.
