Jeryong Industrial (147830) 🔎 In-depth
KOSDAQ · Price as of 2026-08-06 · Updated 2026-08-09
Jeryong Industrial makes and sells transmission, distribution, underground-cable, telecom, and railway materials for power and telecommunications infrastructure, producing many product types in small lots to customer order, so which customers it signs and which supply contracts it wins drives the revenue trend. In March 2026 it secured supply contracts of ₩21.5 billion and ₩9.1 billion (30.9% of recent annual revenue) in quick succession, building an order base comparable to last year's full-year revenue, alongside profitability of a 27.9% operating margin and 13.3% ROE plus a 4.9% dividend yield. What stands out recently is that if the large contracts signed in March flow through to revenue and profit as scheduled and additional orders are added, the low-price appeal of a 7.25x forward P/E, a -55.2% position versus the 52-week high, and an RSI of 26 could come to life, but if follow-on volume dries up after a large contract ends, quarterly results could become more uneven.

Core valuation metric
This stock's effective sub-sector is “Machinery & Electrical Equipment” (Shipbuilding, Machinery, Defense & Power Equipment), a type typically read first through P/E.
Machinery and electrical-equipment makers build and sell industrial gear, and orders and shipments feed fairly directly into profit. Because revenue translates cleanly into current-year net income, price-to-earnings (P/E) is the natural first lens.
Price against earnings alone becomes unstable when earnings swing. Reading it together with price against assets helps gauge the downside.
This note explains how each sector is typically valued and is educational context only, not investment advice.

🔎 In-depth analysis Reading
Jeryong Industrial is a company that makes and sells metal materials used in power and telecommunications infrastructure. Its mainstays are transmission materials, distribution materials, underground-cable materials, telecom equipment, and railway materials, covering the equipment that sends and distributes electricity over distance and the parts used in underground and railway sections. The business divides broadly into metal products and synthetic-resin products. Its head office is in Gwangjin-gu, Seoul, its production plant in Okcheon, North Chungcheong, and its technology research institute in Yuseong-gu, Daejeon. Most products are made in small lots across many types to customer order, so which customers it deals with and which supply contracts it signs drives the revenue trend.
The latest close is ₩6,750 and the market capitalization is ₩135.0 billion. The price sits above its 20-day moving average (₩6,244) and below its 60-day moving average (₩7,544). Short-term and medium-term trends are diverging, so the direction is best read separately. The RSI (a supplementary indicator that gauges the strength of gains versus losses over the past 14 days on a 0-100 scale) is 53.4, a neutral level. The one-month change is -2.2%, the three-month change is -44.6%, and the position relative to the 52-week high is -50.8%. Relative strength versus the KOSDAQ is 71 (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 72% of all stocks. Over the past three months it lagged the index by 22.2%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.
Recent annual revenue is ₩37.9 billion, with operating profit of ₩10.6 billion and net profit of ₩11.5 billion. The operating margin is 27.9% and the net margin is 30.3%, thick margins for a component maker, and ROE (how much a company earns in a year on its own equity) is 13.3%, above the peer average. The debt ratio is 11.4%, the current ratio (assets readily available versus debt due within a year) is 959%, and the interest coverage ratio (how many times operating profit can cover interest) is 288x, so the finances are solid. The P/E of 10.71x and P/B of 1.43x shown now are figures calculated on last year's annual results. For a company like this one, whose earnings jump sharply within a single year, the forward P/E of 7.56x recalculated on this year's increased earnings is closer to actual value. This 6.89x is even lower than Semyung Electric (8.33x), a close comparable within the peer set, so the share price is on the cheap side relative to earnings.
Revenue paused once, from ₩40.9 billion in 2023 to ₩29.3 billion in 2024, before rebounding +29.3% to ₩37.9 billion in 2025; that same year operating profit rose +158.6% and net profit +84%, a recovery far larger than the top line. The trend grew clearer this year, with Q1 2026 revenue up +82.8% year on year, operating profit up +92.0%, and net profit up +96.6%. Behind this rapid earnings expansion are materials demand from power-grid replacement and expansion and from telecom and railway facility investment, along with high-margin order volume. In Q1 alone it posted operating profit of ₩4.8 billion, already accumulating results close to half of last year's full year (₩10.6 billion), and for the full year figures of about ₩52.0 billion in revenue, ₩15.3 billion in operating profit, and ₩17.9 billion in net profit can be gauged. The supply contracts in hand and the Q1 results support these figures, so the picture of a large earnings increase this year rests on clear grounds.
On March 17, 2026, the company issued a corporate value-up plan as a voluntary disclosure, presenting its own plan for shareholder value and business direction. Supply-contract disclosures followed that same month, with a ₩21.5 billion contract on March 16 and a ₩9.1 billion contract (30.9% of recent annual revenue) on March 30 confirmed. Combined, the two contracts are comparable in size to last year's full-year revenue, making them a core foundation for revenue recognition this year and next. Because whether these deals are one-offs or continuing, repeat orders is the point that separates the medium-term trend, it is worth watching additional order disclosures alongside them.
This is a stock with relatively clear strengths. Profitability is good with a 27.9% operating margin and 13.3% ROE, its finances are stable on both debt and liquidity, and its dividend yield is high at 4.9% (a 50% payout ratio). Above all, with this year's earnings rising sharply, the forward P/E has come down to 6.89x, placing it cheaper relative to earnings than comparables in the same industry. On top of that, the share price is -55.2% versus its 52-week high with an RSI of 26, a short-term oversold zone, so improving results and the price position are at odds with each other. The condition that works strongly is when the large supply contracts signed in March flow through to revenue and profit as scheduled and additional orders are added. The point to watch, by contrast, is that revenue depends heavily on order contracts, so if follow-on volume dries up after a large contract ends, quarterly results could become more uneven. In the end, confirming the continuity of supply contracts each quarter is the most important gauge for reading this company.
🔎 Valuation vs peers Fairly valued
A peer set of metal-fabrication companies with adjacent market capitalization.
| Peer | P/E | P/B | ROE |
|---|---|---|---|
| Wooyang HC | — | 0.73x | -2.34% |
| Semyung Electric | 8.86x | 1.26x | 14.78% |
| Shinhwa Pretech | — | 1.14x | -6.40% |
The primary reference was a public-data peer set within metal fabrication with close market capitalization. The current P/E (how many times a year's earnings the share price is) is 11.75x, and the P/B (how many times book value the share price is) is 1.57x. That said, for smaller-cap stocks, earnings volatility and financing disclosures carry heavy weight, so the conclusion was not drawn from last year's confirmed-results metrics alone. The basis for the outlook box is a DART seasonality approximation.

Key metrics Computed vs sector median
Valuation
The P/E of 11.75x is below the sector median (14.98x). The P/B of 1.57x is above the sector median (0.78x). 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.
Profitability & financials
Return on equity (ROE) is 16.4%, above the sector average (1.0%). The operating margin is 29.1%. The debt ratio is 17.7%, so the financial structure is stable.

📖 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 (%).
