Wonik Holdings: Sharp Share Price Rebound Alongside Thin Operating Profit and a Model Value Well Below the Market Price

Thesis

The data supports a company with sizeable revenue that has shrunk since 2022 and whose operating profit has nearly disappeared. Revenue fell from ₩881.0B in 2022 to ₩623.0B in 2025, and operating margin dropped from 11.9% to -0.1% over the same period. Trailing net income of ₩55.1B (9.4% margin) is far above operating income of ₩1.7B, so profit seems to come from items outside core operations; the data does not say which ones. Free cash flow was positive at ₩66.9B. The share price rose 16.1% in one month and 36.1% over one year, but the data does not explain the move, and no news headlines are available. Several recent filings, including a rights offering decision, a treasury share sale decision, a change of largest shareholder amendment and a put-back option contract decision, point to corporate and capital structure activity, though the data gives no details on terms or purpose.

Business overview

Wonik Holdings is listed on KOSDAQ and classified in the Chemicals sector. It was founded on 1991-09-19 and listed on 1996-09-24, with 77,237,981 listed shares and co-CEOs Jo Nam-seong and Jang Seong-dae. Market cap is about ₩2.0T and enterprise value about ₩2.05T. Revenue was ₩844.4B in 2021, peaked at ₩881.0B in 2022, then declined to ₩749.5B in 2023, ₩645.5B in 2024 and ₩623.0B in 2025. The data gives no segment breakdown, so we cannot say what drives these trends.

Financial analysis

All figures come from filed financial statements (DART). For the twelve months to H1 2026, revenue was ₩588.0B, operating income ₩1.7B (0.3% margin) and net income ₩55.1B (9.4% margin). Return on equity was 5.5%. Annual operating income was ₩104.998B in 2022 (11.9% margin), ₩45.8B in 2023, ₩30.6B in 2024 and -₩0.4B in 2025. Net income was ₩128.8B in 2022, then losses of ₩31.7B in 2023 and ₩74.5B in 2024, and a profit of ₩27.4B in 2025. Liabilities-to-equity was 53.5%. Cash was ₩116.1B against borrowings of ₩157.5B, leaving net debt of about ₩41.4B on the model's calculation. Trailing free cash flow was ₩66.9B, though the model uses a lower ₩39.1B.

Valuation

Current multiples are a P/E of 36.4, P/B of 1.9, P/S of 3.4 and a dividend yield of 0.1%; EV/EBITDA is not available. The P/E is based on earnings that are well above operating income. At the end of 2025 the P/E was 137.4 and P/B 3.8, so P/B is lower now than then; earlier year-end multiples are not available. Among the listed peers, P/B is 0.5 for LG Chem, 0.6 for Hanwha, 0.6 for Hanwha Solutions, 0.4 for KCC and 1.8 for SKC, so Wonik Holdings sits at the high end. Peer P/E is available only for Hanwha (10.3) and KCC (1.1). Our simple five-year discounted cash flow model (growth -5.0%, discount rate 9.0%) gives a fair value range of ₩4,442 (bear), ₩5,725 (base) and ₩7,493 (bull) per share. The share price of ₩25,950 is well above even the bull case. The model is simple and relies on a modest cash flow base and negative growth, so it is only one reference point.

Catalysts

• The 2026-08-28 rights offering (paid-in capital increase) decision could change the share count and balance sheet, though terms are not in the data.
• The 2026-09-15 treasury share sale decision may affect share supply and capital structure.
• The amended filing on a change of largest shareholder (2026-08-28) and the 5%+ holding report (2026-09-04) point to ownership changes that investors may watch.
• The H1 2026 report (2026-08-14) and the amended 2025 annual report (2026-09-23) offer updated financial information.
• The put-back option contract decision filed on 2026-08-28 is a major corporate matter whose details are not in the data.

Risks

• Operating income is almost zero (₩1.7B on ₩588.0B of revenue), so earnings rely on non-operating items.
• Revenue has fallen for several consecutive years, from ₩881.0B in 2022 to ₩588.0B on a trailing basis.
• The share price is far above the model's fair value range, which leaves it exposed if results do not improve.
• Borrowings of ₩157.5B exceed cash of ₩116.1B, and a rights offering could dilute existing holders.
• Investor flow, foreign ownership and short balance data are unavailable, so the drivers of recent price gains cannot be assessed.

Closing view

The evidence is mixed. The share price has risen strongly and trailing net income and free cash flow are positive, but core operating profit is close to zero and revenue has declined for several years. The shares trade at 1.9 times book value and 36.4 times earnings, and well above our model range of ₩4,442 to ₩7,493. Recent filings show significant capital and ownership activity, but the data lacks the details needed to judge it. Readers should check the filings directly and look at whether operating profit recovers.
