Doosan Enerbility Co., Ltd.
Korean maker of nuclear reactors, gas turbines, and power plant equipment.
On the record
Checkpoint: Q2/Q3 2026 earnings, watched for whether operating and net margins recover as the record order backlog converts to revenue
The call
Orders are piling up faster than profit is, so the company's nuclear position looks strong while the numbers say watch how that backlog turns into cash.
Doosan Enerbility builds critical metal parts for nuclear power plants, like reactor vessels and steam generators. It is hard to replace because only a handful of companies worldwide have the special certifications, massive forging equipment, and government contracts needed to do this work, and competitors like GE Vernova, Siemens Energy, and Mitsubishi Heavy Industries would take years to catch up. The puzzle is this: the company took in record orders in 2025, yet its net profit dropped 48 percent at the same time. The real test comes in the next two quarters of 2026, when we will see if those huge orders finally turn into healthy profits, or if something went wrong with costs that would signal real trouble ahead.
Why
01
AI pressure: None apparent. AI is a customer here, not a predator: data center power demand is driving its gas turbine and nuclear orders higher. Could AI do the core job? Unlikely.
02
Bigger players: GE Vernova, Siemens Energy, Mitsubishi Heavy Industries. In gas turbines these three outsell and outscale Doosan, though its first US turbine export in 2025 shows it can win deals anyway. Could a giant copy it? No, they are blocked.
03
What protects it. Government backed nuclear EPC ties and forging capacity that let it build reactor vessels almost no other company is qualified to make.
What would change this call
Doosan's Q2/Q3 2026 earnings show operating and net margin trend versus FY2025's 25% and 48% declines. Tests whether record orders are converting to profit or costs are eroding margins.
Dukovany construction start date holds at or before 2029 without delay announcements. Confirms execution capability on the flagship Czech nuclear contract.
Shanghai Electric or Dongfang Electric win a major emerging-market nuclear tender before end of 2026. Would show Chinese state rivals capturing deals Doosan is targeting.

Key numbers
- FY2025 net profit fell 48% to KRW 205.2B
- Q4 2025 orders more than doubled to KRW 14.7tn
- Czech Dukovany reactor contract worth $4.1bn signed
Named risks
- Margin compression despite record order intake, net profit down 48% in FY2025.
- Dukovany construction start set for 2029 faces EU state-aid and legal challenge exposure.
- Gas turbine business remains small challenger against entrenched >70% Big Three share.
- AI data-center capex slowdown could reduce gas turbine export pipeline through 2028.
- Ongoing Doosan Group divestitures reshuffle consolidated scope and reported headcount.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| GE Vernova | contesting | Holds part of >70% Big Three gas turbine share as of Oct 2025 while Doosan made first export |
| Siemens Energy | contesting | Part of Big Three dominating >70% gas turbine market share, Oct 2025 |
| Mitsubishi Heavy Industries | contesting | Rival in hydrogen-turbine race and nuclear equipment as Doosan pushes faster commercialization, 2026 |
| Westinghouse Electric | gaining on | Doosan-led Team Korea won $4.1bn Dukovany deal Dec 2025 over Western nuclear incumbents |

Questions people ask
- Is Doosan Enerbility profitable in 2026?
- Doosan Enerbility remains profitable but margins are shrinking. FY2025 net profit fell 48% year over year to KRW 205.2 billion despite revenue growing 5.1% to KRW 17.0578 trillion, reported February 12, 2026, as record orders have not yet converted into profit.
- Could AI replace Doosan Enerbility?
- No. Doosan Enerbility's core business is physical nuclear reactor vessel and steam generator fabrication plus decades of regulatory licensing, moats AI software cannot replicate. AI is instead boosting its order book by driving data-center power demand, as seen in its first-ever gas turbine export deal signed October 15, 2025.
- Who is Doosan Enerbility's biggest competitor?
- In gas turbines, GE Vernova, Siemens Energy, and Mitsubishi Heavy Industries control over 70% of the global market as of October 2025, making Doosan Enerbility a challenger there, though it holds a near-monopoly position in nuclear reactor-component fabrication.
- Who owns Doosan Enerbility?
- Doosan Enerbility (KRX: 034020) is a publicly listed company within the Doosan Group conglomerate, with a market capitalization of roughly $29.9 to 30.2 billion USD as of July 14, 2026, per PitchBook.
- What is Doosan Enerbility's biggest recent contract?
- The largest recent deal is the Czech Dukovany nuclear reactor-equipment supply contract with KHNP, valued at KRW 5.64 trillion (about $4.1 billion USD), signed December 2025, followed by a KRW 320 billion steam-turbine follow-on contract via Doosan Skoda Power in February 2026.
- Is Doosan Enerbility benefiting from the AI boom?
- Yes. Doosan Enerbility signed its first-ever gas turbine export, two 380MW units for a US big-tech data-center LNG plant, October 15, 2025, and expanded its NVIDIA partnership in June 2026 to supply turbines and SMRs for NVIDIA's DSX AI-factory power platform.
