Doosan Fuel Cell makes and sells large fuel-cell systems installed at power plants and earns steady income servicing them for more than 20 years after installation under long-term service agreements (LTSAs); its phosphoric-acid (PAFC) M400 line is the mainstay, and it is broadening its lineup into the solid-oxide type (SOFC) and expanding new businesses such as water electrolysis, marine power, and data-center power. In its preliminary first-quarter 2026 results in April, a surge in revenue and a narrowing operating loss were confirmed, and at the end of April it signed a system supply contract (₩60.8 billion) and a 20-year LTSA (₩49.1 billion) with Ansan Green Power at once, while in May the roughly 17 MW supply-contract value with Samchully ES (₩52.9 billion) was disclosed. What stands out lately is that revenue is growing at double digits or more, the first-quarter operating result has improved close to breakeven, orders including a 20-year LTSA are raising the quality and durability of revenue, and clean-hydrogen policy provides support; on the other hand, net profit is still in the red, and the financing burden of a 326% debt ratio could hold back a swing to profit, so how fast orders convert into revenue and profit is the crux.

🔎 In-depth analysis

🏢Business
  • Doosan Fuel Cell earns money by making and selling large fuel-cell systems installed at power plants and then servicing them over a long period after installation.
  • A fuel cell is a device that reacts hydrogen drawn from city gas, hydrogen, or LPG with oxygen from the air to make electricity and heat, and a single plant takes several-MW-class (megawatt) equipment.
  • Its mainstay product is the phosphoric-acid (PAFC) M400 line, and recently it has been broadening its lineup into the higher-efficiency solid-oxide type (SOFC).
  • The larger axis of revenue is the initial supply contract that delivers the system, and on top of this a long-term service agreement (LTSA) that manages the delivered equipment for more than 20 years attaches as a steady income source.
  • Domestic power operators (for example, Samchully ES and Ansan Green Power) are the main customers, and it is also broadening new businesses such as water electrolysis (equipment that splits water with electricity to make hydrogen), marine power, and data-center power.
📈Price & chart
  • The latest close is ₩42,850 and the market cap is ₩2.8 trillion.
  • The price sits below its 20-day line (₩59,452) and below its 60-day line (₩67,739).
  • Trading under both its short- and mid-term moving averages, the trend is on the subdued side.
  • The RSI (a supplementary gauge that weighs upward against downward force over the past 14 days on a 0-100 scale) is 28.4, close to a slump zone.
  • The one-month change is -40.4%, the three-month change is +24.2%, and the position versus the 52-week high is -57.8%.
  • Relative strength against the KOSPI is 56 (1-99, computed from returns versus the index over the past year with more weight on recent periods; higher means stronger than the market).
  • That places it in roughly the top 43% of all stocks by strength.
  • Over the past three months it lagged the index by 5.7%.
  • Chart reading is best done alongside trading volume and disclosure dates.
📊Key metrics
  • On valuation, earnings-based metrics do not hold.
  • Because of the 2025 net loss, the P/E ratio (how many times a year's earnings the share price is) cannot be calculated, and EPS (earnings per share) is -₩2,028.
  • Instead, at a P/B (how many times net assets the share price is) of 7.64x and a P/S (how many times revenue the share price is) of 8.56x, the level is high, reflecting expectations for growth and orders rather than results.
  • Profitability is still in the red, with ROE (how much it earns in a year per unit of equity) at -36.1% and an operating margin of -23.2%.
  • Financials are on the burdened side, with a debt ratio (debt against equity) of 326%, which is why interest and financing costs keep eating into net profit.
  • That said, it matters that the large 2025 loss was concentrated in the fourth quarter (a fourth-quarter operating loss of -₩76.6 billion), and that the first-quarter 2026 operating loss narrowed to -₩1.3 billion, close to breakeven.
  • On last year's confirmed results alone it looks burdensome, but as a company passing an earnings inflection, the ongoing flow should be weighed alongside.
🚀Growth
  • Revenue is on a growth track.
  • It rose from ₩260.9 billion in 2023 to ₩411.8 billion in 2024 (+57.8%) and ₩454.8 billion in 2025 (+10.4%), a two-year average of 32%, and first-quarter 2026 revenue of ₩144.8 billion was up 45.2% from a year earlier.
  • Profit and loss, by contrast, swung from a slight profit in 2023 to losses in 2024-2025, the result of new-business investment overlapping with costs concentrated in the fourth quarter of 2025.
  • The key is the direction of profit and loss.
  • The operating loss shrank sharply from -₩76.6 billion in the fourth quarter of 2025 to -₩1.3 billion in the first quarter of 2026, an early signal that profitability is recovering as revenue grows.
  • Future profit depends on how fast new system-supply volume is recognized as revenue and on how much steady, stable-margin service revenue such as the 20-year long-term service (LTSA) accumulates.
  • That said, a swing to net profit requires operating profit to exceed the financing costs arising from high debt, and at this point, with no material offering an official annual target from the company, it is hard to pin this year's net profit to a specific figure.
📰Recent news & filings
  • In 2026, meaningful disclosures have come from both results and orders.
  • The April preliminary-results disclosure confirmed a surge in revenue and a narrowing operating loss, and at the end of April it signed a system supply contract (₩60.8 billion) and a 20-year long-term service agreement (LTSA, ₩49.1 billion) with Ansan Green Power at once, securing both early revenue and long-term service revenue.
  • In May, the previously withheld contract value of the roughly 17 MW fuel-cell system supply contract signed with Samchully ES (₩52.9 billion) was disclosed.
  • Such supply and service orders form the basis for future revenue and margin recovery.
🧭Bottom line
  • The points that look positive are clear.
  • Revenue is growing at double digits or more, the first-quarter 2026 operating result has improved close to breakeven after the large fourth-quarter 2025 loss, and the quality and durability of revenue are improving as orders including a 20-year long-term service (LTSA) accumulate.
  • A policy environment that institutionally supports clean-hydrogen power also underpins demand for power-generation fuel cells.
  • On the other hand, the points to note are equally clear.
  • Net profit is still in the red, and with a debt ratio of 326% the financing burden could hold back a swing to net profit.
  • How fast orders convert into actual revenue and profit, and how shifts in government-auction market volume feed through to results, are the crux.
  • In sum, this is a company at an earnings inflection where the direction of revenue growth and profit-and-loss improvement is good, but a firmly established net profit and eased financial burden still need confirming.
  • It is reasonable to follow whether revenue growth and a narrowing loss actually continue quarter by quarter.

🔎 Valuation vs peers Inconclusive

The peer set is domestic listed names within the ecosystem of power- and industrial-use fuel cells and hydrogen and power equipment. Bumhan Fuel Cell is a direct fuel-cell peer (though its sub-field differs, centered on marine and hydrogen refueling), and Doosan Enerbility is a large-cap power-equipment name in the same group with business adjacency.

PeerP/EP/BROE
Bumhan Fuel Cell88.21x0.87x0.99%
Doosan Enerbility553.29x6.02x1.09%

(a) Position versus peers: at a P/B of 10.6x it is far higher than the direct peer Bumhan Fuel Cell (P/B of 1.4x) and higher even than the group-adjacent name Doosan Enerbility (7.28x). (b) Premium/discount: a premium for scale, order base, and growth potential in stationary power-generation fuel cells is reflected, making the asset-value multiple higher than peers. (c) Limits of trailing metrics: with the 2025 net loss, the P/E does not hold and EPS and ROE are negative, so undervaluation or overvaluation cannot be declared on an earnings basis. With no official annual company target disclosed, forward net profit is also hard to pin to a figure. In the end, this is a stock that should be assessed on revenue growth, order backlog, and the pace of profit-and-loss improvement rather than an earnings multiple, so rather than declaring it cheap or expensive on current metrics alone, Inconclusive is correct.

📖 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 (%).
