Sungho Electronics Corp. (043260) recorded ₩426.5 billion of finance income in the first quarter of 2026. Its revenue that quarter was ₩66.0 billion.
One line on the income statement came to roughly six and a half times everything the company sold. Almost everything strange about how this stock is priced follows from that single entry, and any screen that ranks Korean small caps by earnings multiple has been quietly telling investors the wrong thing about this company since April.
The first quarter produced ₩410.7 billion of pretax income, ₩91.2 billion of tax expense, and ₩319.5 billion of net income. Operating income in the same three months was ₩3.2 billion.
Add the last four reported quarters and trailing net income is ₩361.4 billion. Against a market capitalisation of ₩1.2 trillion at Monday's close, that is the 3.23 times earnings the screens display. The arithmetic is correct. What it measures is not profit from selling anything.
Two other multiples sit on the same page and disagree loudly. Price to sales is 4.36 and price to book is 2.77. When one ratio says a stock is among the cheapest on the exchange and the other two say it is expensive, the odd one out is almost always the earnings line, because earnings is the only one of the three that a revaluation can move by a factor of a hundred in ninety days.
Here is the same company measured by what it operates rather than what it holds.
Trailing revenue over the four quarters through June was ₩267.0 billion. Trailing operating income was ₩14.7 billion. Against the same ₩1.2 trillion of market value, that is roughly 79 times operating profit.
Both numbers come from the same filings. One of them is 3.2 and the other is 79, and the difference is entirely what sits below the operating line. A reader who buys this on the earnings multiple is not buying ₩361 billion of earning power. They are buying a components manufacturer with a large and volatile portfolio of financial assets attached.
The second quarter showed which way that portfolio can move. Finance income was negative ₩34.2 billion, pretax income was a loss of ₩47.4 billion, and the company reported a net loss of ₩46.0 billion. Three months after the largest profit in its history, it lost money.
The quarterly figures don't identify what the gain and the reversal were marked against. The income statement records the amounts as finance income and finance costs, and nothing in the summary lines names the underlying asset. The notes to the half-year report are where that answer lives, and anyone taking a position on this company should read them before trusting either quarter.
This is the part the marks obscure, and it is the more encouraging half of the story.
Second-quarter revenue was ₩85.2 billion, up 50.7% from ₩56.6 billion a year earlier. Operating income was ₩6.9 billion against ₩1.3 billion, more than a fivefold increase. First-half revenue of ₩151.2 billion was up 30.6% year on year, and first-half operating income of ₩10.1 billion was more than triple the ₩2.9 billion of a year before.
Zoom out and the trend holds. Annual revenue has climbed from ₩107.2 billion in 2020 to ₩231.6 billion in 2025. Operating income is thinner and choppier, at ₩7.6 billion in 2025 against ₩25.9 billion in 2023, but the direction of the top line is not in doubt.
That is a real business improving at a real rate. It is also a business whose entire trailing operating profit is about 1.3% of the company's market value.
Total assets were ₩581.1 billion at the end of 2025. Three months later they were ₩1,355.5 billion, and at the end of June ₩1,359.3 billion.
The funding is visible in the cash flow statement. Across the first half of 2026 financing activities brought in ₩555.6 billion and investing activities consumed ₩510.7 billion. Operating activities used ₩30.2 billion, so the operating business was a net drain on cash in both quarters while the investment programme ran.
Liabilities moved accordingly, from ₩327.1 billion at the end of 2025 to ₩938.7 billion at the end of June, with non-current liabilities rising from ₩76.8 billion to ₩438.3 billion. Equity finished the half at ₩420.7 billion, down from ₩585.1 billion three months earlier. Retained earnings only fell ₩46.3 billion over that quarter, so most of the ₩164.4 billion decline in equity came from somewhere other than the loss, and the summary figures don't say where.
Some of that funding is dilutive by construction. The company filed convertible bond issuance reports on five occasions between August 5 and August 31, and warrant exercise notices on July 26, August 26 and August 27. Stated share capital has gone from ₩30.5 billion at the end of 2024 to ₩35.8 billion at the end of June, a 17.3% increase in eighteen months.
In August it also put ₩20.0 billion of cash into DES Holdings Co., Ltd., buying 50,000 redeemable convertible preferred shares to reach 100% ownership. DES Holdings makes semiconductor chillers, was established in October 2025, and reported no revenue and a ₩7 million loss. The stated purpose was strengthening control of a subsidiary. That is 7.1% of Sungho's equity going into a ten-month-old company in a business its flat-panel components heritage does not obviously cover.
The most important filing this company has made this year is not an earnings release.
Seoryong Electronics Co., Ltd., the largest shareholder, holds 27,448,301 shares, or 37.37% of the 73,433,552 outstanding. It has pledged 27,410,601 of them. That is 99.86% of its stake and better than a third of the entire company, committed as collateral under a single loan agreement dated April 2. The filing states plainly what happens if the pledge is enforced: the holding falls to 37,000 shares, or 0.05%.
Korea requires a dedicated disclosure for exactly this, a share pledge contract accompanied by a change of largest shareholder. There is no clean US equivalent, and the form is unusually explicit, because it makes the borrower publish the share count at which control leaves the building.
The terms matter. The facility totals ₩300 billion with a 200% collateral requirement, giving the ₩600 billion pledge figure in the filing, and ₩165 billion was outstanding as of the September 1 amendment after five early repayments across July. Enforcement is triggered by missed payments, by insolvency proceedings at the borrower or at the issuer of the pledged shares, or by the collateral ratio falling below 200% without additional collateral inside three business days.
The purpose of the borrowing, as disclosed, was acquiring another company. Seoryong Electronics itself reported ₩6.9 billion of revenue and ₩2.4 billion of net income in its last financial year, against ₩286.3 billion of assets. The filings name the same person, Park Sung-jae, as chief executive of Seoryong Electronics and of DES Holdings.
The third-quarter report should show whether the first-quarter gain survives at anything like its recorded value, and the notes should name the asset. That is the difference between a company that earned ₩361 billion and one that briefly marked it.
After that, the collateral ratio is the number to follow. A pledge covering better than a third of the shares, tested at 200% with three business days to cure, means a sustained fall in the stock can force the sale of the controlling block into the same falling market. That mechanism has nothing to do with how many components the company ships, and it is the risk least visible in any of the three valuation multiples printed on this page.
