Hy-Lok Corporation (013030) 🔎 In-depth
KOSDAQ · Price as of 2026-08-06 · Updated 2026-08-09
Hy-Lok Corporation makes the instrumentation fittings, valves and tubing that go into chemical, refining, semiconductor, shipbuilding and gas plant sites, with precision machining of stainless steel and special alloys into a wide variety of leak-critical parts at the heart of its technology. On May 8 it reported Q1 revenue of ₩54.1 billion and operating profit of ₩15.7 billion for double-digit growth, and with a 27.5% operating margin and 11.1% ROE it delivers profitability above peer parts names while trading at lower P/E and P/B than they do and paying a dividend in the 4% range. The point to watch: in a phase where multiple front-end capex streams - semiconductors, shipbuilding and plants - stay alive and margins hold, profitability, dividend and valuation all provide support; against that, revenue is tied to the front-end industries' capex cycle, so if investment slows, order and earnings momentum can weaken together.

Core valuation metric
This stock's effective sub-sector is “Steel & Metals” (Chemicals, Refining, Steel & Materials), a type typically read first through P/B.
Steel and metals swing hard with raw-material prices and downstream demand, so profits balloon in upturns and can flip to losses in downturns. Because earnings are so volatile, price-to-book (P/B) — the share price against the value of plant and assets — is the first lens.
Price against assets alone says little about where the cycle stands. Reading it together with price against this year's expected earnings shows how far profits have recovered.
This note explains how each sector is typically valued and is educational context only, not investment advice.

🔎 In-depth analysis Reading
Hy-Lok Corporation makes the instrumentation fittings (parts that join pipe to pipe leak-free), valves and tubing that go into industrial sites such as chemical, refining, semiconductor, shipbuilding, offshore and gas plants. Because these are parts that must never leak in environments where liquids, gases or corrosive substances flow, the core of the business is the technology to precision-machine stainless steel and special alloys to high quality and specification. Rather than mass-producing a single type, it makes a wide variety of standard-spec and made-to-order products the customer requires, moving in step with front-end industries' capital investment and export conditions. Recently, areas with steady demand for precision parts - clean-energy facilities such as LNG and hydrogen, and semiconductor plant expansions - have supported revenue.
The latest close is ₩32,650 and the market capitalization is ₩384.2 billion. The price sits above its 20-day moving average (₩31,098) and below its 60-day moving average (₩33,649). 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 53.8, a neutral level. The one-month change is +5.3%, the three-month change is -27.1%, and the position relative to the 52-week high is -29.2%. Relative strength versus the KOSDAQ is 69 (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 70% of all stocks. Over the past three months it outpaced the index by 10.8%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.
On a confirmed annual (2025) basis, the P/E ratio (the price divided by earnings per share) is 7.64x and the P/B ratio (the price divided by net asset value per share) is 0.84x, so it trades even below net assets. Both metrics place the price on the cheap side relative to earnings and assets rather than the expensive side. ROE (how much was earned in a year on equity) is 11.1% and the operating margin is 27.5%, delivering profitability above the sector average. The debt ratio is 9.6%, but most of this is non-interest-bearing operating liabilities, and as a 1,390% current ratio and 30x interest coverage show, it has ample capacity to repay - a stable financial structure. The dividend yield is also high, in the 4% range, making this a stock where profitability, financial strength and dividend all provide support together.
Five-year revenue rose from ₩146.7 billion in 2021 to ₩214.6 billion in 2025, growing about 10% a year on average, and operating profit also climbed steadily over the same period from ₩18.9 billion to ₩58.9 billion. In 2025, revenue rose 12.6% and operating profit 17.5% year on year, quickening the pace of increase again, and in the most recent quarter, Q1 2026, revenue of ₩54.1 billion (+10.4%), operating profit of ₩15.7 billion (+23.5%) and net profit of ₩15.3 billion (+32.2%) showed earnings growing faster than revenue. This resulted from a larger share of higher-priced products and supportive cost management thickening margins even while making the same precision parts. With orders being filled in a phase where front-end capex in semiconductors, shipbuilding and LNG stays alive, this year's earnings are expected to be a step above last year's for the full year as well, and the forward P/E reflecting this comes down to 6.27x. There is no clear basis to view next year onward as lower than this year, so it is early to declare the current earnings level a cycle top.
The recent disclosure flow splits into two strands: shareholder returns and results confirmation. On March 20, 2026 the company decided a cash dividend, continuing the consistency of its capital-efficiency and shareholder-return policy, and on May 8 it announced preliminary Q1 results, reporting revenue of ₩54.1 billion and operating profit of ₩15.7 billion for double-digit growth. On May 15 the quarterly report confirmed the preliminary figures unchanged, and on May 21 it held an investor briefing (IR) where the company explained its business status and outlook to the market directly. Voluntarily holding an IR beyond mandatory disclosures can be read as a signal of both confidence in results and a willingness to communicate.
This is a stock with clear strengths. It supplies precision parts to different front-end industries - semiconductors, shipbuilding and plants - so it does not depend on any single one, and with a 27.5% operating margin and 11.1% ROE it delivers profitability above peer parts names (Sungkwang Bend ROE 6.3%, TK Corporation ROE 10.2%) while trading at lower P/E and P/B than they do and paying a dividend in the 4% range. It is a setup that reads as undervalued: doing the same business better while trading more cheaply. On top of that, a forward P/E of 6.81x reflecting this year's earnings growth, together with asset value (P/B 0.80x), provides downside support. The caution is that revenue is tied to the front-end industries' capex cycle, so if semiconductor, shipbuilding and plant investment slows, order and earnings momentum can weaken together. In short, in a phase where front-end capex stays alive and margins hold, it is a strong stock where profitability, dividend and valuation all provide support; in a phase where front-end investment cools or the exchange rate turns unfavorable, the shrinking of the earnings-growth margin is its weak point.
🔎 Valuation vs peers Fairly valued
The comparison uses names with verifiable site figures within the same business group that makes parts for front-end facilities and piping (fittings, valves and pipe couplings); the closest direct competitor, DK-Lok (105740), is often cited but is excluded from the numeric comparison as there is no site data for it.
| Peer | P/E | P/B | ROE |
|---|---|---|---|
| Sungkwang Bend | 20.75x | 1.29x | 6.10% |
| Taekwang | 9.35x | 0.92x | 12.75% |
(a) Position versus peers: against fellow parts makers Sungkwang Bend (P/E 21.5, P/B 1.35, ROE 6.3%) and TK Corporation (P/E 10.6, P/B 1.08, ROE 10.2%), Hy-Lok Corporation has the lowest multiples at P/E 7.76 and P/B 0.86 yet the highest ROE at 11.1%. With better profitability but lower multiples, it sits at a discount versus peers. (b) Premium/discount factors: its status as a small-mid KOSDAQ name and concern over volatility tied to the front-end capex cycle act as a discount, while high profitability, cash and dividends act as a premium, offsetting each other. (c) Limits of trailing and the forward basis: a P/E of 7.76x is on last year's confirmed earnings, so if this year's earnings grow the forward multiple falls further. Plugging in a seasonality approximation adjusted with DART confirmed results (this year's net profit of about ₩56.7 billion) brings the forward P/E down to about 6.9x, but this is an unverified approximation, not an official company outlook. Taken together, with multiples low relative to profitability, financial strength and dividends, it is hard to view as overvalued, but factoring in front-end cycle volatility we see it as roughly fairly valued.

📖 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 (%).
