CS Wind is the world's number-one maker of wind towers, the pillars of wind turbines, having supplied more than 13,000 units worldwide; it delivers to global turbine makers such as Vestas and Siemens Gamesa from plants in eight countries including Vietnam and the U.S., and in 2023 it broadened into offshore-wind substructures by acquiring Denmark's Bladt. Q1 2026 was confirmed on May 7, 2026 with revenue of ₩711.1 billion, operating profit of ₩74.3 billion, and net profit of ₩43.9 billion, followed by three IR sessions, a decision on debt guarantees for a subsidiary, and a corporate governance report and other administrative disclosures. The point to watch is that, with its world-leading position, production bases in eight countries, and two growth axes in U.S. onshore and European offshore, net profit that was depressed by a 2025 impairment returned to a normal track in Q1, so reflecting this recovery brings the headline P/E of 53x down sharply; but a 174.8% debt ratio and 2.33x interest coverage leave a financing-cost burden, and this is a policy-sensitive industry where a wind-down of U.S. tax support and offshore-wind policy drive the order flow.

🔎 In-depth analysis

🏢Business
  • CS Wind makes wind towers, the 'pillar' of the wind turbines that generate electricity from wind, and is the world's number-one player in the field, having supplied more than 13,000 units worldwide to date.
  • It has plants in eight countries including Vietnam, the U.S., Portugal, China, Turkey, and Taiwan, and delivers towers to global turbine makers such as Vestas and Siemens Gamesa.
  • At the end of 2023 it acquired Denmark's Bladt, a specialist in offshore-wind substructures (the foundation structures that fix a turbine to the seabed), broadening its business from onshore towers to offshore foundations.
  • Revenue splits mainly into a tower segment and a substructure segment; as of Q1 2026, towers were ₩597.6 billion and substructures ₩113.5 billion, so the tower share is large.
📈Price & chart
  • The latest close is ₩39,200 and the market cap is ₩1.7 trillion.
  • The price sits below its 20-day line (₩43,212) and below its 60-day line (₩52,571).
  • Trading under both its short- and medium-term moving averages, the trend is on the soft side.
  • RSI (a supplementary gauge that weighs upward against downward force over the last 14 days on a 0-100 scale) is 39.9, a neutral level.
  • The one-month change is -5.2%, the three-month change is -40.2%, and the position versus the 52-week high is -49.0%.
  • Relative strength versus the KOSPI is 29 (1-99, computed from returns against the index over the past year with recent performance weighted more heavily; higher means stronger than the market).
  • That places it in roughly the top 71% of all stocks by strength.
  • Over the last three months it has lagged the index by 51.3%.
  • Chart reading is best done alongside trading volume and disclosure dates.
📊Key metrics
  • The valuation surface looks heavy.
  • The P/E ratio (how many years of profit the price represents) is high at 53x, and ROE (how much is earned in a year on equity) is just 3.0%.
  • But this is because 2025 net profit (₩34.7 billion) was unusually low.
  • In the same year operating profit actually rose to ₩320.3 billion (up 25.4% year on year), while only net profit fell 75.6%.
  • The reason is a large impairment at an offshore-wind subsidiary: when a U.S. project cancellation cut off work at the Danish monopile plant (Lindoe), the company booked a one-off accounting charge marking down asset values sharply.
  • Because this charge involves no cash outflow, it is a temporary item and should be separated from the ongoing operating strength of the business.
  • For reference, the U.S. plant receives a tax credit for domestic production (AMPC); at about ₩95.1 billion last year, this equaled 37% of operating profit, contributing structurally to earnings.
  • The debt ratio (debt against equity) is somewhat high at 174.8% and interest coverage is 2.33x, a structure with a financing-cost burden.
  • P/B (the price relative to book equity) is 1.43x and the dividend yield is 2.3% (₩1,000 per share).
  • The cash flow is also worth noting: EV/EBIT (enterprise value including debt divided by operating profit) is low at 8.1x and the FCF yield (actual cash generated relative to market cap) is high at 23.5%, so even though accounting net profit was depressed by a one-off, the real cash-generating power is solid.
🚀Growth
  • Over five years, revenue grew from ₩1.20 trillion in 2021 to ₩3.07 trillion in 2024, then eased to ₩2.93 trillion in 2025, while operating profit rose clearly over the same span from ₩101.1 billion to ₩320.3 billion.
  • Net profit plunged from ₩142.3 billion in 2024 to ₩34.7 billion in 2025, not because of operating weakness but because of the one-off impairment at the offshore-wind subsidiary.
  • In fact, Q1 2026 net profit of ₩43.9 billion already surpassed the entire 2025 full-year net profit (₩34.7 billion) in a single quarter.
  • In other words, net profit has hit bottom and is returning to a normal level.
  • Q1 revenue and operating profit fell year on year largely because Q1 of the prior year was unusually strong, a negative base effect.
  • The offshore-wind subsidiary had a work gap in the second half of last year, but new substructure orders have secured this year's revenue, so that concern has cleared.
  • In the U.S., onshore-wind orders are being pulled forward ahead of the reduction in tax support, and the company sees the U.S. tax credit staying at around ₩120 billion a year.
  • On these grounds, this year's earnings are on a trajectory clearly pointing up from the depressed 2025 level.
  • Reflecting this recovery, even though the current price looks to carry a high P/E on last year's results, it sits at a much lower multiple on this year's earnings basis.
📰Recent news & filings
  • On May 7, 2026, a consolidated preliminary results disclosure confirmed Q1 revenue of ₩711.1 billion, operating profit of ₩74.3 billion, and net profit of ₩43.9 billion.
  • In May the company held three IR sessions in succession (5/11, 5/18, 5/22), strengthening communication with investors, and on May 15 it disclosed a decision on debt guarantees for third parties, showing that the funding-support structure for its production subsidiaries remains in place.
  • On May 22 large-holding and ownership-change filings related to treasury shares followed, and a corporate governance report came on May 29 and an executive and major-shareholder ownership report on June 1.
  • Rather than standalone disclosures of major new orders, the quarter was dominated by administrative disclosures such as periodic reports, IR, and stake/guarantee items.
🧭Bottom line
  • The strong case is clear.
  • There is the world-leading tower-making position, production bases in eight countries, and two growth axes in pulled-forward U.S. onshore orders and European offshore substructures; and net profit, temporarily depressed by the 2025 impairment, had already returned to a normal track by Q1 2026.
  • Reflecting this recovery, the headline 53x P/E comes down sharply on this year's earnings basis, so it is hard to call the stock expensive on last year's results alone.
  • The cautions are equally clear.
  • With a 174.8% debt ratio and 2.33x interest coverage, there is a financing-cost burden, so rates and exchange rates can amplify net-profit volatility.
  • And as a policy-sensitive industry where the timing of the U.S. tax-support wind-down and offshore-wind policy direction drive the order flow, a wobble in order visibility would shake the earnings trajectory too.
  • In the end, this is a structure where an earnings recovery supports the valuation while policy and orders hold, and where high leverage becomes a burden in a policy-retreat phase.

🔎 Valuation vs peers Undervalued

Korean-listed peers within the wind value chain. SK Oceanplant, which overlaps in offshore-wind substructures, is the closest by business, while Unison, a wind-turbine maker, is a value-chain reference.

PeerP/EP/BROE
SK Oceanplant21.99x1.02x4.64%
Unison0.00x2.11x-19.74%

A headline P/E of 53x looks higher than the peer SK Oceanplant (25.8x), but this is an illusion created by 2025 net profit (₩34.7 billion) being unusually low due to the one-off impairment at the offshore-wind subsidiary. In the same year operating profit actually rose to ₩320.3 billion, and Q1 2026 net profit of ₩43.9 billion already surpassed the full 2025 figure, with earnings returning to a normal track. On this year's earnings basis reflecting that recovery, the multiple falls sharply to a level below SK Oceanplant's current P/E. Given the world-leading position and dual growth axes, it is hard to call the stock overvalued on last year's trailing results alone, and on a forward view that reflects the earnings inflection it is seen as undervalued territory. The high debt ratio, however, should be weighed together as a discount factor.

📖 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 (%).
