Iljin Holdings does not make products itself; it holds stakes in Iljin Group operating companies and earns money through dividends, trademark royalties, and rental income as an operating holding company. Most of its ₩2.28 trillion in consolidated revenue comes from the power-equipment business of listed subsidiary Iljin Electric, with industrial-diamond and composite-materials affiliates adding to the mix. In Q1 2026, revenue of ₩572.9 billion and operating profit of ₩52.1 billion (+61.1%) showed subsidiary profit growing quickly, and in April a corporate value-up plan laid out a direction for shareholder returns and capital-efficiency improvement, while some potential dilution from mezzanine exercises remains. What stands out lately is that a forward P/E of 5.46x and a P/B of 0.58x are lower than peer holding companies, and its market cap (about ₩302.0 billion) is deeply discounted against the value of its listed holdings (about ₩2.0 trillion); on the other hand, results are concentrated at Iljin Electric alone, so the power-equipment cycle effectively drives the stock's direction.

Financial healthModerate
  • For financial companies, debt and interest costs are large by the nature of the business, so the debt ratio and interest coverage cannot be read on the same yardstick as an ordinary company.
GrowthHigh growth
  • Revenue rose 26.8% year over year, and the pace is quickening (3-year trend: rising).
  • Most recent quarter (Q1 2026) revenue was 13.3% higher than a year earlier.

💡 How to read a holding company · A holding company owns stakes in several subsidiaries. Its P/E swings with equity-method gains and losses on those stakes, so read it only as a rough guide. P/B is more meaningful because subsidiary stakes sit in equity, but book value carries them at low historical cost (so P/B looks higher than reality). The most accurate view is the price against the market value of those stakes (NAV)

🔎 In-depth analysis

🏢Business
  • Iljin Holdings is not a company that makes and sells products directly; it is an operating holding company (one whose enterprise value centers on subsidiary stakes) that holds stakes in Iljin Group's various operating companies and earns money through dividends, trademark royalties, and rental income.
  • On the accounts, however, most of its ₩2.28 trillion in consolidated revenue comes from listed subsidiary Iljin Electric.
  • In other words, the substance behind the revenue and operating-profit growth shown on screen is effectively the power-equipment business, to which industrial-diamond and conductive-materials as well as composite-materials affiliates (including hydrogen-storage vessels) are added.
  • So in looking at this company, one must consider both "how much the subsidiaries the holding company owns earn" and "how much of that stake value is reflected in the share price."
📈Price & chart
  • The latest close is ₩5,560 and market capitalization is ₩274.4 billion.
  • The price sits below its 20-day line (₩6,452) and below its 60-day line (₩8,815).
  • Trading below both the short- and medium-term moving averages, the trend is subdued.
  • The RSI (a supplementary gauge that measures upward versus downward momentum over the last 14 days on a 0-100 scale) is 30.3, at a neutral level.
  • The one-month change is -18.9%, the three-month change is -20.2%, and the position versus the 52-week high is -61.3%.
  • Relative strength versus the KOSPI is 23 (on a 1-99 scale, computed from returns against the index over the past year with more weight on recent performance; higher means stronger than the market).
  • That places it in roughly the top 77% of all stocks by strength.
  • Over the past three months it lagged the index by 38.8%.
  • Chart readings are best viewed alongside trading volume and disclosure dates.
📊Key metrics
  • On confirmed full-year 2025 figures, the P/E (how many times one year's profit the share price trades at) is 7.80x and the P/B (how many times net assets the price trades at) is 0.52x, trading below net assets.
  • The ROE (how much is earned in a year on equity) of 6.7% is above the peer holding-company average, and the operating margin is 6.4%.
  • The debt ratio (debt relative to equity) of 445.7% looks high, but this figure lumps in the borrowings and working capital of consolidated subsidiaries and differs from the holding company's standalone burden.
  • With an interest-coverage ratio of 4.2x and a current ratio of 1.6x, short-term coverage is reasonable.
  • One important point is that this P/E and P/B are on last year's confirmed figures.
  • Because this is a profit-inflection phase where this year's earnings are rising quickly, looking only at last year's multiples makes it appear more expensive than it is.
  • The forward P/E on this year's profit falls to 5.46x and the forward P/B to 0.52x, which is the real picture: a signal of undervaluation that is in fact lower than peer holding companies.
🚀Growth
  • Five-year revenue grew from ₩1.2 trillion in 2021 to ₩2.3 trillion in 2025, about 17.7% a year on average (24.5% over the last two years), and over the same span operating profit rose roughly 3.8x from ₩38.7 billion to ₩145.6 billion.
  • Looking at 2025 alone, revenue rose +26.8% and operating profit +100.8%, with profit growth far outpacing revenue and the pace itself accelerating.
  • In Q1 2026 the profit leverage carried straight through, with revenue of ₩572.9 billion (+13.3%), operating profit of ₩52.1 billion (+61.1%), and net profit of ₩39.1 billion (+55.5%).
  • The reason is clear: core subsidiary Iljin Electric is posting record-level results as utilization and prices rise together amid strong demand for transformers and power equipment, backed by a multi-year order backlog.
  • The forward P/E on this year's profit reflecting this is 5.46x, well below last year's confirmed P/E of 8.58x.
  • In other words, this is not a picture of growth stalling but of this year's profit stepping up another level, and at the current price the stock sits cheaper against that expanded profit.
📰Recent news & filings
  • Among this year's disclosures, the one carrying weight is the April 22, 2026, corporate value-up plan (voluntary disclosure).
  • It is a document in which the company itself laid out a direction for shareholder returns and capital-efficiency improvement, a starting point for gauging whether an undervalued holding company trading below net assets is moving to close the discount.
  • In April-May, disclosures of the disposal of shares in other corporations related to subsidiary stakes followed (April 17, 2026; amended May 15, 2026), showing the holding company's portfolio adjustment is under way.
  • The May 15 quarterly report officially confirmed Q1 revenue of ₩572.9 billion and operating profit of ₩52.1 billion (+61.1%).
  • Meanwhile, the April 29, 2026, disclosure on the exercise of conversion, warrant, and exchange rights is a variable to watch together, since mezzanine (such as convertible bonds) exercises increase the share count and can somewhat dilute existing holders' stakes.
🧭Bottom line
  • The strengths are distinct.
  • As core subsidiary Iljin Electric's profit grows quickly, the holding company's consolidated results grow with it, and the forward P/E on this year's profit of 5.46x and forward P/B of 0.52x are lower than peer holding companies.
  • On top of that, the parent's market cap (about ₩302.0 billion) is deeply discounted against the value of its listed holdings (about ₩2.0 trillion), a textbook picture of an undervalued holding company whose parent is priced cheap against subsidiary value.
  • The company also releasing a corporate value-up plan gives an opening for that discount to narrow.
  • What to watch is that most results are concentrated at Iljin Electric alone, so the power-equipment cycle effectively drives the stock's direction, and that dilution from mezzanine exercises remains.
  • In short, this stock is especially strong "when the subsidiary's power-equipment strength continues and the NAV discount narrows" and weak "when the power-equipment cycle turns down or dilution overlaps." Considering this year's expanded profit together with the deep stake-value discount, the current price reads as closer to the undervalued side.

🔎 Valuation vs peers Undervalued

Rather than a simple revenue-wholesale classification, comparison uses the substance of an "operating holding company," placing same-industry holding companies (LG, Doosan) alongside listed subsidiary Iljin Electric, which is the substance behind the consolidated results. Figures are the site's own calculated values (at the current price).

PeerP/EP/BROE
LG Corp21.19x0.54x2.57%
Doosan257.06x12.49x4.86%
Iljin Electric28.60x5.05x17.65%

Versus peer holding company LG, the P/B is similar, the ROE (6.7%) is higher, and profit growth is much faster. Above all, given the nature of an operating holding company, the key is the discount of the parent's market cap against subsidiary stake value. The market cap of listed subsidiary Iljin Electric alone is about ₩3.9 trillion, while the parent holding company sits at about ₩345.9 billion, so a large discount against stake value is observed. Also, last year's trailing P/E of 9.8x is limited because this is a profit-inflection phase, and applying forward profit approximated from DART seasonality in place of official guidance (operating profit of about ₩198.5 billion, net profit of about ₩111.3 billion) lowers the multiple further. That said, this approximation is unverified and subsidiary-industry and dilution risks remain, so rather than concluding outright that it is cheap, one should watch whether the conditions for the discount to close come together.

📖 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 (%).
