Why this report
Start of coverage: written when a reader opened this company and there was no report yet.
Dongsung Finetec reports trailing revenue of ₩770.2B and net income of ₩79.5B, yet its share price closed at ₩12,910, down 59.0% over one year. Current multiples are well below the company's own year-end history, and the model estimate sits above the market price.

Thesis
The filings show several years of rising revenue and margins, with operating margin moving from 3.5% in 2022 to 12.8% on a trailing basis. The share price has moved the other way, falling 19.2% in one month, 12.2% in three months and 59.0% in one year, and it sits near the 52-week low of ₩12,520 (high ₩32,650). The data does not explain the gap between earnings and price, and no news headlines are available. Trailing free cash flow is negative at -₩11.5B, which the data supports as a point of caution against the strong profit figures. Foreign ownership eased from 16.8% to 16.1% over 60 days, and short balance is only 0.1%.
Business overview
Dongsung Finetec is listed on KOSDAQ and classified in the Chemicals sector. It was founded on 1985-07-31 and listed on 1997-12-19, with 29,989,494 shares outstanding and a market capitalisation of about ₩387.2B. Revenue grew from ₩365.0B in 2021 to ₩742.2B in 2025. Recent filings include several major sales or supply contract disclosures and amendments between April and July 2026, but the data does not give contract values or counterparties.
Financial analysis
Figures come from filed financial statements. Revenue was ₩742.2B in 2025, up 24.2%, after growth of 12.4% in 2024 and 22.4% in 2023. Operating income rose from ₩15.3B in 2022 to ₩72.6B in 2025, and net income reached ₩55.9B in 2025. Trailing to H1 2026, revenue is ₩770.2B, operating income ₩98.9B (12.8% margin) and net income ₩79.5B (10.3% margin). Return on equity is 32.3% trailing, versus 24.2% in 2025 and 5.8% in 2022. Liabilities to equity are 74.6%, cash is ₩50.2B and borrowings are just ₩250M. Free cash flow is negative at -₩11.5B.
Valuation
On trailing figures the stock trades at a P/E of 4.9, P/B of 1.3, P/S of 0.5 and EV/EBITDA of 3.1, with a dividend yield of 3.1%. Its own year-end P/E ranged from 11.4 to 13.6 in 2023-2025 (38.6 in 2022 on depressed earnings), and year-end P/B was 2.2 to 2.9. Listed peers show P/B between 0.3 and 2.1; P/E is available for only two peers (6.3 and 0.9), so the comparison is limited. The valuation model, a 5-year discounted cash flow at a 7.4% rate, gives a model estimate based on the assumptions shown of ₩42,491 per share in the base case, ₩24,051 bear and ₩73,651 bull. All three are above the ₩12,910 close. This is not a target or a reason to buy or sell, and the result depends heavily on the assumptions.
Catalysts
- Several major sales or supply contract filings and amendments (April, June and July 2026) show ongoing order activity, though values are not given in the data.
- The half-year report filed 2026-08-14 supplied the latest trailing earnings, and the next periodic report will show whether margins hold.
- Over 20 days foreign investors were net buyers of about ₩1.0B and retail about ₩1.5B, while institutions were net sellers of about ₩2.4B.
- A disposal of treasury shares was reported on 2026-04-30, and an insider shareholding report was filed on 2026-05-08.
Risks
- The share price has fallen 59.0% in a year and 19.2% in the last month, and the data gives no reason for the decline.
- Trailing free cash flow is negative at -₩11.5B despite reported profits of ₩79.5B.
- Margins and ROE are at multi-year highs, so any reversal would weigh on earnings that the low multiples rely on.
- The model estimate is sensitive to its assumptions, as shown by the wide range from ₩24,051 to ₩73,651.
- Foreign ownership slipped from 16.8% to 16.1% in 60 days, and institutions were net sellers over the last 20 days.
Closing view
The filings show strong growth in revenue, profit and returns, a nearly debt-free balance sheet and multiples far below the company's own history, while the share price has dropped sharply and free cash flow is negative. The model estimate is above the current price in all three cases, but it rests on assumptions and does not explain why the market is pricing the company so differently. The data is mixed, and the key unanswered question is the cause of the price decline, which is not in the information available.
