Thesis

The data supports a story of sharply higher revenue and a very large share price move. The data does not show that the move is explained by operating performance. TTM operating margin is 5.5%, while net margin is 135.3%, which means net income is mostly coming from something other than core operations. The data does not say what that source is, so the headline P/E of 5.2 should be read with caution. Free cash flow is negative at ₩63.4B and borrowings are ₩324.5B against cash of ₩44.7B. Filings in August to October 2026 show convertible bond issuance, a bond with warrants decision, warrant exercises, and a change of largest shareholder. Investor flow, foreign ownership, short balance and news data are not available, so we cannot say who is driving the trading.

Business overview

Sungho Electronics is a KOSDAQ-listed electronic components company, founded in 1973 and listed on 2001-11-29, with 61,002,189 listed shares. CEO is listed as 박성재. Revenue has grown from ₩133.2B in 2021 to ₩231.6B in 2025, and TTM revenue to H1 2026 is ₩267.0B. The 52-week range runs from ₩1,155 to ₩59,600, so the current ₩30,700 sits well below the high but far above the low. The data does not describe products or customers.

Financial analysis

From filed financial statements (DART): revenue was ₩133.2B in 2021, ₩153.6B in 2022 (+15.3%), ₩208.1B in 2023 (+35.5%), ₩207.3B in 2024 (-0.4%) and ₩231.6B in 2025 (+11.7%). Operating income was ₩1.2B, ₩2.0B, ₩25.9B, ₩6.3B and ₩7.6B over the same years, with operating margin of 0.9%, 1.3%, 12.4%, 3.0% and 3.3%. Net income was ₩3.2B in 2021, a loss of ₩4.2B in 2022, ₩17.6B in 2023, ₩8.1B in 2024 and ₩91.0B in 2025. TTM to H1 2026 net income is ₩361.1B on operating income of ₩14.7B, with ROE of 130.0%. Liabilities to equity is 223.1%. Cash is ₩44.7B, borrowings ₩324.5B and free cash flow -₩63.4B.

Valuation

Current P/E is 5.2, P/B 4.5 and P/S 7.0; enterprise value is ₩2.15T. EV/EBITDA and dividend yield are not available. The P/E is low mainly because trailing net income is unusually large relative to operating income. Year-end 2025 P/E was 6.2 and P/B 2.2, so P/B has roughly doubled since then. Peers show P/E of 17.1 (LG Innotek) to 110.2 (Samsung Electro-Mechanics) and P/B of 1.8 to 10.9, so Sungho's P/E is below all five listed peers while its P/B of 4.5 sits in the middle. Our simple five-year DCF model could not produce a fair value range (fair_value_model is null), so we cannot compare the ₩30,700 price with a model estimate.

Catalysts

  • A bond with warrants issue decision was amended on 2026-10-06 and again on 2026-10-13, which may change future share count and funding.
  • An investor relations event was held on 2026-10-06, which may have given more company information.
  • A convertible bond call option designation was reported on 2026-09-18, which relates to how existing convertible debt may be handled.
  • A change of largest shareholder and a 5%+ holding report were filed on 2026-09-01, pointing to a shift in ownership.
  • The next financial statements will show whether the large non-operating net income and negative free cash flow persist.

Risks

  • Net income is far larger than operating income, so earnings quality and repeatability are unclear from the data.
  • Convertible bonds, warrants and bonds with warrants could dilute existing shareholders.
  • Borrowings of ₩324.5B far exceed cash of ₩44.7B, and liabilities to equity is 223.1%.
  • Free cash flow is negative at ₩63.4B, so operations are not funding investment.
  • The 2581.2% one-year price gain leaves the shares exposed to sharp swings, and flow and short-interest data are not available to judge positioning.

Closing view

The evidence is mixed. Revenue growth and a very large share price rise are clear, and headline multiples such as P/E of 5.2 look low. However, they rest on net income that is far above operating profit, while cash flow is negative, leverage is high, and recent filings show ongoing capital raising and an ownership change. With no model fair value, flow data or news available, the data leaves the key questions about the source of profit and the sustainability of the rerating unanswered.

Model estimate of fair value

The valuation model has no estimate for this company yet (not enough data, or no positive value with the base case).
