Ilseung is an equipment-and-materials company classified in the shipbuilding sector. Last year it posted annual revenue of ₩50.7 billion, operating profit of ₩10.9 billion and net profit of ₩7.5 billion, showing a structure that converts a modest top line into solid profit. In the quarterly report filed on May 14, 2026, Q1 2026 revenue of ₩12.1 billion, operating profit of ₩2.3 billion and net profit of ₩3.7 billion confirmed an improving-earnings trend, and with an operating margin of 21.4% and an ROE of 16.3% pointing to good profitability, the share price still sits -67.3% below its 52-week high with an RSI of 28.1, leaving price and results pointing in opposite directions. The point to note is that if the widened margin holds into the next quarter the current price looks cheap relative to profit, whereas because the earnings improvement came from margin rather than revenue growth, it is worth checking whether this margin level is sustainable, along with the financial trend implied by a debt ratio of 281.7%.

🔎 In-depth analysis
- Ilseung is an equipment-and-materials company classified in the shipbuilding sector.
- Last year's annual revenue was ₩50.7 billion, with operating profit of ₩10.9 billion and net profit of ₩7.5 billion, a structure that leaves good profit relative to its revenue scale.
- Given its small-cap nature, not only the business itself but each quarterly earnings disclosure tends to have a large effect on the financials and the share price, so it helps to watch the flow of disclosures alongside it.
- The latest close is ₩3,020 and the market cap is ₩92.8 billion.
- The price sits below its 20-day line (₩3,575) and below its 60-day line (₩4,639).
- Trading under both its short- and medium-term moving averages, the trend looks subdued.
- The RSI (an auxiliary gauge that compares upward and downward force over the past 14 days on a 0-100 scale) is 32.9, a neutral level.
- The one-month change is -19.6%, the three-month change is -42.7%, and the position versus the 52-week high is -69.5%.
- Relative strength versus the KOSDAQ is 43 (1-99, computed from the past year's return against the index with heavier weight on recent performance; higher means stronger than the market), placing it in roughly the top 57% of all stocks by strength.
- Over the past three months it lagged the index by 24.9%.
- When reading the chart, it helps to look at volume and disclosure dates together.
- Last year's annual revenue was ₩50.7 billion, with operating profit of ₩10.9 billion and net profit of ₩7.5 billion.
- The operating margin of 21.4% is high, and the ROE (how much is earned in a year on equity) of 16.3% makes the profitability assessment 'excellent.' The debt ratio (debt versus equity) of 281.7% means debt somewhat exceeds equity, but a current ratio of 366% and an interest-coverage ratio of 6.25x mean short-term payment capacity and the ability to cover interest are ample.
- The trailing (on last year's confirmed results) P/E is 13.36x and the P/B is 2.02x, which look ordinary by the numbers alone; but this company is at an inflection where profit is rising quickly, so assessing it on last year alone risks missing the real picture.
- On this year's profit, the forecast P/E is clearly below the peer set (Daeyang Electric 6.14x, Halla IMS 9.24x), reading as an undervalued signal.
- The assessment is likewise 'undervalued.'
- Revenue was roughly flat, at ₩53.0 billion in 2023, ₩51.8 billion in 2024 and ₩50.7 billion in 2025, but earnings tell a different story.
- Operating profit grew from ₩5.3 billion in 2023 to ₩10.9 billion in 2025, up +57.1% year over year, and net profit jumped +328.9%.
- In the most recent quarter, Q1 2026, this trend grew even clearer, with revenue up +20.4% year over year, operating profit up +228.0% and net profit up +263.6%.
- In other words, with revenue similar, the margin improved sharply and profit jumped.
- This year's forecast is around revenue of ₩54.6 billion, operating profit of ₩35.6 billion and net profit of ₩37.6 billion, a result of already earning ₩3.7 billion of net profit in the first quarter plus a trend of margins rising each quarter.
- The backdrop to this profit growth is that a backlog is being realized as profit and the operating margin has stepped up a level; because profit grows even as revenue stalls, margin improvement rather than the top line is the key driver.
- On 2026-02-27, a revenue and earnings-structure change filing disclosed last year's annual results (revenue ₩50.7 billion, operating profit ₩10.9 billion, net profit ₩7.5 billion), and on 2026-03-23 the annual report confirmed these figures.
- Then, in the 2026-05-14 quarterly report, Q1 2026 results (revenue ₩12.1 billion, operating profit ₩2.3 billion, net profit ₩3.7 billion) confirmed the improving-earnings trend.
- Given that it is a small-cap, earnings disclosures such as quarterly reports and earnings-structure changes are likely to remain a major variable for the share price going forward.
- Ilseung's strengths are clear.
- With an operating margin of 21.4% and an ROE of 16.3%, profitability is good, and as quarterly profit rises markedly, this year's forecast P/E has come down into undervalued territory versus peers.
- The share price is down -67.3% from its 52-week high with an RSI of 28.1, so the price has fallen sharply while profit, conversely, is improving, and the divergence between price and results stands out.
- The point to examine is that revenue itself is not growing and the earnings improvement comes from margin, so whether this margin level holds into the next quarter is the key.
- The debt ratio of 281.7% is also somewhat high, so it helps to check the financial trend as well as the results.
- In short, if the widened margin holds, the current price looks cheap relative to profit; if the margin falls back, that appeal weakens.

Within shipbuilding, we prioritized a public-data comparison set close in market cap. The current P/E ratio (how many times a year's profit the share price is) is 12.45x and the P/B (how many times book value the share price is) is 2.02x. That said, for smaller-cap names, swings in profit and funding disclosures carry a large effect, so we did not draw firm conclusions from last year's confirmed results alone. The forecast box is based on a DART seasonality approximation.

Price history Close · MA20 · MA60
The latest close is ₩3,020 and the market capitalization is ₩92.8 billion. The price sits below its 20-day moving average (₩3,575) and below its 60-day moving average (₩4,639). It is under both its short- and medium-term moving averages, so the trend looks subdued. The RSI (a supplementary indicator that gauges the strength of gains versus losses over the past 14 days on a 0-100 scale) is 32.9, a neutral level. The one-month change is -19.6%, the three-month change is -42.7%, and the position relative to the 52-week high is -69.5%. Relative strength versus the KOSDAQ is 43 (on a 1-99 scale, converted from returns against the index over the past year with more weight on recent performance; higher means stronger than the market). It is stronger than roughly 43% of all stocks. Over the past three months it lagged the index by 24.9%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.

Key metrics vs sector median
Valuation
The P/E is 12.45x. The P/B of 2.02x is above the sector median (1.64x). That said, this P/E is based on last year's (trailing) results. With recent quarterly earnings up sharply, the trailing P/E can look higher than it really is, so a precise read is best done on this year's expected (forward) earnings.
Enterprise value (EV)
EV = market cap + net debt. It reflects cash and debt, so it captures the real cost of the whole business that market cap alone misses; lower multiples are cheaper relative to earnings or sales.
Intrinsic value (DCF estimate)
DCF (discounted cash flow) estimate — discount rate 11.3%, initial growth 4.0%→terminal 2.0%, 10-yr forecast, free-cash-flow basis. A reference range that shifts materially with assumptions.
Profitability & financials
Return on equity (ROE) is 16.3%, in line with the sector average (15.0%). The operating margin is 21.4%. The debt ratio is 281.7%, so the financial structure is somewhat high.

📖 Plain-language glossary — expand if you are new to this
- P/E
- How many times a year's net profit the price is worth (lower is cheaper relative to earnings). The P/E here is on trailing (last full-year) results; for companies whose earnings swing fast (memory chips and other cyclicals/high-growth), a forward P/E on this year's expected earnings is more accurate.
- P/B
- Price relative to net assets (equity). Around 1x means it trades near book value; below 1x means below book.
- P/S
- Price relative to a year's revenue — useful for growth companies with thin earnings.
- Net debt / EV
- Net debt = interest-bearing debt − cash. Negative means more cash than debt (net cash). EV (enterprise value) = market cap + net debt, closer to what it would cost to buy the whole business.
- EV/EBIT · EV/EBITDA · EV/Sales
- Enterprise value against operating profit (EBIT), EBITDA, or revenue. Unlike P/E these reflect debt and cash; lower is cheaper relative to earnings power or sales.
- FCF / FCF yield
- Free cash flow = operating cash − capex, the cash actually left over. FCF yield = FCF ÷ market cap; higher means more cash generated per unit of market value.
- Intrinsic value (DCF)
- Future free cash flow (or, for some capex-heavy but profitable names, forecast earnings) discounted to today to estimate per-share value. Because it shifts a lot with the discount-rate and growth assumptions, it is shown as a bear/base/bull range, and the basis and assumptions are disclosed in one line beneath it.
- ROE
- How much profit the company earns in a year on its equity (%). Higher means better returns on capital.
- EPS / BPS
- Earnings per share / net assets (book value) per share.
- Operating / net margin
- Profit left from the core business / final profit after tax and interest, per unit of revenue.
- Debt ratio
- Debt relative to equity (%). Higher means more reliance on borrowing (norms vary by sector).
- Current ratio
- Assets convertible to cash within a year against debt due within a year. Above 100% leaves some short-term headroom.
- Interest coverage
- How many times operating profit covers the interest owed. Below 1x means operating profit alone struggles to cover interest.
- Dividend yield / payout ratio
- The year's dividend as a % of today's price / the share of earnings paid out as dividends.
- Revenue CAGR
- Multi-year growth expressed as a single yearly average (compound annual growth rate).
- RSI (short-term signal)
- Whether recent price action is overheated or beaten down. Above 70 is overbought, below 30 oversold.
- MA20 / MA60 (moving averages)
- The 20- and 60-day average price. Price above them signals a firmer short-term trend.
- vs 52-week high
- How far below the past year's peak the price sits now (%).
