Thesis

The data supports a picture of a company under financial and ownership strain. Revenue was ₩19.8B in 2025, up 6.0%, and the operating loss narrowed from 2024, but the company has not reported a profitable year at the operating level except for a break-even 2023 (0.2% margin). Trailing twelve-month revenue to H1 2026 was ₩18.7B with an operating loss of ₩5.3B, so the improvement has not clearly continued. On the other side, liabilities are low relative to equity at 24.0%, and cash of ₩13.1B is close to borrowings of ₩16.1B. The price-to-book ratio of 0.9 is far below the 2.6 to 13.5 seen at year-ends since 2021, but that mostly reflects equity eroded by large past losses and a collapsed share price. The data does not show whether the business can return to profit. A recent news headline from Money Today questions when the company will recover funds tied to its affiliates, but the data gives no further detail.

Business overview

The company is listed on KOSDAQ in the Electronics sector, was founded in 1999 and listed in 2001. It has 11,109,170 listed shares and a market capitalisation of about ₩93.8B. Revenue has been volatile: ₩13.0B in 2021, ₩29.1B in 2022 (up 123.0%), ₩26.3B in 2023, ₩18.7B in 2024 (down 28.9%) and ₩19.8B in 2025. Foreign ownership is small at 3.8%, unchanged over 60 days, and the short balance is 0.9%. The data does not describe its products or customers in detail.

Financial analysis

These figures come from filed financial statements. Net losses were ₩17.2B in 2021, ₩18.3B in 2022, ₩48.4B in 2023, ₩76.8B in 2024 and ₩5.5B in 2025. Operating margins were -35.6%, -18.7%, 0.2%, -41.7% and -23.0% over the same years. For the twelve months to H1 2026, operating income was -₩5.3B (margin -28.3%), net income -₩2.2B (margin -11.8%) and ROE -2.2%. Free cash flow was -₩4.5B. Cash of ₩13.1B compares with borrowings of ₩16.1B, and liabilities are 24.0% of equity. Net loss being smaller than operating loss in the latest period suggests non-operating gains, but the data does not identify them.

Valuation

The price-to-book ratio is 0.9, versus year-end readings of 2.6 (2025), 9.6 (2024), 3.6 (2023), 6.9 (2022) and 13.5 (2021). Price-to-sales is 5.0 and enterprise value is ₩91.1B. P/E and EV/EBITDA are not available because earnings are negative, and the dividend yield is 0.0%. Peers show P/E of 8.7 (Samsung Electronics), 24.7 (LG Electronics), 16.4 (Hanwha Vision) and 37.6 (RFHIC), and P/B of 1.0 to 4.9 including KMW at 4.9; these companies are far larger, so comparison is limited. No model estimate per share is available, because the valuation model could not be worked out for this company. The share price of ₩8,440 sits near the 52-week low of ₩7,900 and far below the 52-week high of about ₩43,549.

Catalysts

  • Filings on 2026-09-18 and 2026-10-22 both amended a change of largest shareholder, so control of the company appears to be shifting.
  • Trading halts were recorded on 2026-09-08 and 2026-10-01, and their cause is not stated in the data.
  • A major sales or supply contract was filed on 2026-09-10, though the data gives no size or terms.
  • An Extraordinary Shareholders' Meeting concluded on 2026-08-12, with proxy documents filed in July and August.
  • A Money Today article on 2026-10-19 discusses recovery of funds linked to affiliates.

Risks

  • The company has had operating losses in four of the last five years and an operating margin of -28.3% in the latest twelve months.
  • Free cash flow was -₩4.5B and cash of ₩13.1B is lower than borrowings of ₩16.1B.
  • The share price is down 79.2% over one year and 18.5% over one month, showing high volatility.
  • Changes of largest shareholder and repeated trading halts point to ownership and governance uncertainty.
  • Over 20 days, foreign investors were net sellers of about ₩0.8B while retail investors were net buyers of about ₩0.9B, and trading flows are small relative to the history of losses.

Closing view

The data shows a small company with a long record of losses, a sharp share price decline, and recent ownership changes and trading halts. Against that, the loss at the operating level narrowed in 2025, debt relative to equity is modest, and the price-to-book ratio is below one for the first time in the period shown. Because earnings are negative, no model estimate is available and the data does not show a clear path to profit, the evidence is mixed and leaves significant uncertainty.
