Hyosung Heavy Industries is a heavy-electric-machinery company that makes ultra-high-voltage (UHV) transformers, circuit breakers, motors and power systems such as STATCOM and ESS that go into the grid linking power plants and cities, and it also runs a construction division (with its own apartment brand). In 2025 it posted revenue of ₩5.9685 trillion and operating profit of ₩747.0 billion, doubling operating profit in a single year, and in the first quarter of 2026 revenue rose 26.2% and operating profit 48.8%, building an order backlog of about ₩11.9 trillion as growth continued. The point to watch is that while a shortage of UHV transformers persists on the back of AI data centers and aging-grid replacement, it is strong on high-margin orders led by its U.S. Memphis plant, but with a debt ratio above 200% and non-operating costs such as tariffs and interest weighing on net profit, net profit may not keep pace with the growth in operating profit.

Core valuation metric

Forward P/E (expected earnings)38.81x

This stock's effective sub-sector is “Power Equipment” (Shipbuilding, Machinery, Defense & Power Equipment), a type typically read first through forward P/E.

Power-equipment firms make the transformers and grid gear that move electricity, and their results swing with grid-investment cycles and large project awards. Because the backlog converting into future earnings matters more than results already booked, the forward P/E — reflecting expected earnings — is the first lens.

P/B (price-to-book)10.54x

Price against earnings alone becomes unstable when earnings swing. Reading it together with price against assets helps gauge the downside.

🔎 In-depth analysis Reading

🏢Business

Hyosung Heavy Industries makes the equipment needed along the path electricity travels from power plants to factories and cities. Revenue falls into two broad lines. The first is the heavy-industry division, which makes UHV transformers, distribution transformers, UHV circuit breakers, motors and power systems such as STATCOM (a device that stabilizes voltage), HVDC (long-distance direct-current transmission) and ESS (battery storage that holds electricity). This heavy-industry division's 2025 operating margin was about 17%, a high-margin engine responsible for most of the company's profit. The second is the construction division, which builds apartments under its own housing brand. Construction's operating margin is a low ~5%, but it is a stable pillar supporting revenue scale. The company's real growth driver is heavy industry, especially transformers. Its Memphis, Tennessee plant is the only base able to design and produce 765kV-class UHV transformers within the United States, and on this plant it is directly capturing U.S. grid-replacement demand.

📈Price & chart

The latest close is ₩2,708,000 and the market capitalization is ₩25.3 trillion. The price sits above its 20-day moving average (₩2,607,300) and below its 60-day moving average (₩3,250,817). 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 48.9, a neutral level. The one-month change is -6.7%, the three-month change is -41.1%, and the position relative to the 52-week high is -41.1%. Relative strength versus the KOSPI is 55 (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 55% of all stocks. Over the past three months it lagged the index by 30.0%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.

📊Key metrics

Profitability is clearly good. ROE (how much is earned in a year on equity) is 22.1%, above the sector average. The operating margin is 12.5%, but that is a company-wide figure blended with lower-margin construction; the core heavy-industry business alone is about 17%, higher. On the other hand, the financial burden is clear. The debt ratio (debt relative to equity) is 201.5%, meaning debt exceeds equity, and the interest coverage ratio (how many times operating profit can cover interest) is a low 1.35. In other words, profit is strong but interest costs eat considerably into net profit. Enterprise-value measures make this easy to understand. EV/EBIT (enterprise value including debt divided by operating profit, the debt-inclusive version of the P/E) is around 43x. Net debt (total borrowings minus cash) is about ₩247.6 billion, not large relative to market cap, but total borrowings themselves are high, showing up as an interest burden. The FCF yield (actual cash generated relative to market cap) is about 1%, still low, reflecting the growth-phase trait of heavy capital expenditure and working capital. In sum, "excellent margins and ROE, but note the debt and interest burden" are this company's two faces.

🚀Growth

The scale of growth is large. In 2025 revenue rose 21.9% year-on-year, and the pace of growth is gradually quickening. The grain of profit is steeper still. In 2025 operating profit grew 106% in a single year and net profit rose 133%. The trend continues into 2026. First-quarter revenue rose 26.2% and operating profit 48.8% year-on-year. That said, net profit in the same quarter fell about 12%. The reason is not that the core business weakened but that tariff-related costs (about ₩17.0 billion) and interest expense weighed on net profit below the operating line. In other words, with the core business strengthening while non-operating items eat into net profit, the P/E calculated on last year's basis can look more expensive than reality. The basis for growth is clear. AI data-center power demand and aging-grid replacement in the U.S. and Middle East are overlapping, leaving UHV transformers in chronic shortage, and this shortage is expected to persist broadly through around 2028. The order backlog is about ₩11.9 trillion, up 34% year-on-year, leaving plenty of work to convert into future revenue. The company plans to invest about ₩230.0 billion more in the Memphis plant to raise UHV-transformer capacity by more than 50% by 2028, so revenue has room to grow further as capacity expands. For this reason this year's profit is on a trajectory to exceed last year's, and with grid investment continuing next year (2027) too, there is weak basis for viewing this year as the profit peak.

📰Recent news & filings

Disclosures and company announcements reveal growth and risk together. In February 2026 it signed a roughly ₩787.0 billion contract with a U.S. transmission-grid operator to supply 765kV UHV transformers and reactors. This is the largest single U.S. project ever for a Korean power-equipment company, material that will push up results with high-margin U.S. revenue over the coming years. In April it held an IR to explain the direction of orders and results directly. Conversely, on May 8 it disclosed a serious safety accident; given the nature of manufacturing, safety incidents can lead to operational disruption, cost and reputational risk, and are a point to note. In May there were also disclosures on material management matters relevant to investment judgment and a quarterly report. In sum, a growth event in the form of a large order and risk events in the form of safety and finance coexist in the same period.

🧭Bottom line

Hyosung Heavy Industries is at the center of the large trend of a UHV-transformer shortage. The strengths are clear. It has the only local plant in the United States able to make 765kV transformers, and with a record order and a ₩11.9 trillion backlog it has secured several years of work ahead. ROE of 22% and a 17% operating margin in the heavy-industry division show that this growth is feeding through to profit. The 51x P/E on last year's basis looks high, but given this year's trajectory of further operating-profit growth, the valuation on forward earnings is lower than that. In a growth phase, the "picture on this year's earnings" is closer to reality than the "burden seen through last year's numbers." The cautions are equally distinct. With a debt ratio above 200% and low interest coverage, even when the core business is good, non-operating costs such as interest and tariffs can weigh on net profit so it does not grow as freely as operating profit. On-site risks such as serious safety accidents also persist. In sum, while grid investment and the transformer shortage continue, orders and profit are strong together, but the financial burden and non-operating costs can hold net profit back.

🔎 Valuation vs peers Fairly valued

Compared with domestic power-equipment (transformer, circuit-breaker and power-system) makers: HD Hyundai Electric, LS ELECTRIC, Iljin Electric and Jeryong Electric.

PeerP/EP/BROE
HD Hyundai Electric37.44x13.19x37.84%
LS ELECTRIC105.98x14.69x16.36%
Iljin Electric27.04x4.66x19.39%
Jeryong Electric12.50x3.20x22.65%

On last year's confirmed results the P/E is 51x, not low within the power-equipment peer group. But with profit inflecting upward for this company, it is premature to call it expensive on last year's P/E alone. Operating profit grew 106% in 2025 and 48.8% in the first quarter of 2026, so on this year's earnings the valuation burden is lower than last year's numbers. Against peers its position is in the middle. Its margins and ROE are lower than the most profitable peer, HD Hyundai Electric (P/E 40x, ROE 36%), justifying a correspondingly lower premium, while it is lower than LS ELECTRIC (P/E 105x). With strengths (U.S. orders, the shortage, growth) and weaknesses (high debt, low interest coverage, non-operating costs) in balance, we see the current valuation as a fairly valued level that reflects both growth expectations and the financial burden. For reference, given the nature of the metric, last year's trailing P/E can understate the actual earnings power to the extent net profit is depressed by non-operating costs, so it is appropriate to look at this year's earnings basis alongside it.

📖 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 (%).
