KEY TAKEAWAYS
The key investment drivers for Doosan Enerbility in 2026 are the combined growth of large nuclear power projects, SMR equipment, gas turbines for North American AI data centers, and long-term maintenance services.
Orders in the Enerbility segment reached KRW 14.73 trillion in 2025, more than doubling from the previous year. The order backlog expanded to KRW 24.13 trillion by the end of the first quarter of 2026.
However, large projects take a long time to convert from contracts into recognized revenue. Nuclear and SMR projects are also affected by government policy, licensing, financing, and construction schedules. For the stock to sustain a valuation re-rating, investors will need to see not only new orders but also revenue conversion and operating-margin improvement.
Analysis date: July 18, 2026
1. The Key Questions for Doosan Enerbility in 2026
Doosan Enerbility is an integrated energy infrastructure company that supplies equipment and services for large nuclear power plants, small modular reactors, gas turbines, steam turbines, power plant EPC projects, and long-term maintenance.
In the past, coal-fired power generation and large-scale plant construction represented a significant proportion of the company’s business.
More recently, however, the order portfolio and business structure have shifted toward nuclear power and gas turbines.
In particular, growing electricity demand from AI data centers is creating a new market for gas and steam turbines, while global nuclear expansion policies are generating opportunities for both large nuclear plants and SMR equipment.
Evaluating the Doosan Enerbility stock outlook for 2026 therefore requires more than simply determining whether nuclear or AI-related themes remain popular.
Investors should consider the following questions:
- Will the order backlog of more than KRW 24 trillion convert into actual revenue and operating profit?
- Will nuclear power, gas turbines, and other higher-margin growth businesses contribute a larger proportion of revenue?
- Will North American gas turbine orders for data centers lead to repeat orders and long-term service contracts?
- Will SMR reservation agreements and partnerships convert into full manufacturing contracts?
- Will large overseas nuclear projects proceed according to schedule?
- Can the company control cost inflation and construction delays in combined-cycle EPC projects?
- Will higher net debt decline as cash flow improves?
Doosan Enerbility’s long-term business direction is positive.
However, a sustained valuation re-rating will require repeated evidence that order expectations are translating into revenue, profit, and cash flow.
2. Consolidated Results and the Enerbility Segment Must Be Analyzed Separately
The first point investors should understand is that Doosan Enerbility’s consolidated results differ from the performance of its core Enerbility segment.
The consolidated financial statements include not only Doosan Enerbility’s core operations but also the results of major subsidiaries such as Doosan Bobcat and Doosan Fuel Cell.
The separately disclosed Enerbility segment primarily reflects the performance of the company and its overseas subsidiaries in nuclear power, gas turbines, turbine services, and EPC operations.
Looking only at consolidated operating profit may therefore allow changes in Doosan Bobcat’s performance to obscure improvement or weakness in Doosan Enerbility’s core business.
Investors should monitor both:
- Consolidated results: Final revenue and earnings for the entire corporate group
- Enerbility segment: Orders, revenue, and profitability from nuclear, gas turbine, and EPC operations
The indicators most likely to determine the company’s long-term valuation are the Enerbility segment’s order backlog and operating margin.
3. 2025 Results: Orders More Than Doubled
Orders in the Enerbility segment reached KRW 14.73 trillion in 2025, increasing 106.5% from KRW 7.13 trillion in 2024.
The order backlog increased 42.3%, from KRW 16.20 trillion at the end of 2024 to KRW 23.05 trillion at the end of 2025.
Enerbility segment revenue reached KRW 7.88 trillion, increasing 7% year over year.
Operating profit rose by KRW 58.7 billion to KRW 302.3 billion.
The operating margin improved slightly from 3.3% in 2024 to 3.8% in 2025.
Major contributors to the increase in orders included:
- Nuclear power projects related to the Czech Republic
- North American gas turbine orders
- Domestic gas turbine orders
- Combined-cycle power plant EPC projects in the Middle East and Asia
- Expansion of nuclear and gas turbine service operations
The fact that orders grew significantly faster than revenue indicates that the foundation for revenue growth over the next several years has strengthened.
However, consolidated revenue in 2025 increased 5.1% to KRW 17.06 trillion, while consolidated operating profit declined to KRW 762.7 billion.
This was partly due to higher tariff-related costs and selling, general, and administrative expenses at Doosan Bobcat.
Because the direction of core business orders may differ from the direction of consolidated operating profit, the two sets of results must be interpreted separately.

4. First-Quarter 2026 Results: Order Backlog and Profitability Improved Together
Orders in the Enerbility segment reached KRW 2.79 trillion in the first quarter of 2026.
This represented an increase of 61.8% from the previous year.
At the end of the first quarter, the Enerbility segment’s order backlog reached KRW 24.13 trillion.
This was an increase of 45.9% year over year and 3.8% from the end of 2025.
Revenue increased 20.3% year over year to KRW 1.90 trillion.
Operating profit reached KRW 57.0 billion, turning positive from an operating loss in the previous-year period.
The operating margin was 3.0%.
Revenue growth was supported by Czech nuclear equipment, gas turbines, and progress on combined-cycle EPC projects in the Middle East.
Operating profit improved as revenue increased and nuclear and gas turbine businesses represented a larger proportion of sales.
Consolidated first-quarter 2026 results were as follows:
- Revenue: KRW 4.26 trillion
- Operating profit: KRW 233.5 billion
- Operating margin: 5.5%
- Net income: KRW 60.2 billion
Consolidated operating profit increased 63.9% year over year.
However, the Enerbility segment’s operating margin of 3.0% remains below the company’s medium- and long-term targets.
The key issue is not revenue growth alone, but whether a larger contribution from high-margin nuclear equipment, turbines, and services can steadily improve profitability.

5. 2026 Order Targets and the Medium-Term Business Plan
Doosan Enerbility set a 2026 order target of KRW 13.3 trillion for the Enerbility segment.
The main targets by business are:
- Nuclear power: KRW 4.9 trillion
- Gas and hydrogen: KRW 3.2 trillion
- Combined-cycle EPC: KRW 3.0 trillion
- Renewable energy: KRW 1.2 trillion
- Other businesses: KRW 1.0 trillion
The company aims to increase annual orders to KRW 16.4 trillion by 2030.
The Enerbility segment’s revenue target is KRW 7.4 trillion in 2026 and KRW 11.7 trillion in 2030.
Operating profit is projected to increase from KRW 395.9 billion in 2026 to KRW 1.15 trillion in 2030.
The company aims to improve its operating margin from 5.4% to 9.9% over the same period.
Its order backlog target is approximately KRW 27.2 trillion in 2026 and KRW 47.7 trillion in 2030.
These figures are management targets, not confirmed results.
Actual performance may differ depending on the timing of nuclear, SMR, and gas turbine contracts and the progress of major projects.
Investors should focus less on the long-term targets themselves and more on whether the following indicators remain aligned with the plan each year:
- New orders
- Growth in the order backlog
- Conversion of the order backlog into revenue
- Operating-margin improvement
- Operating cash flow
- Long-term service revenue

6. The Composition of the Order Backlog Matters More Than Its Size Alone
A growing order backlog is positive, but not all orders generate the same level of profitability.
Large EPC projects can generate substantial revenue, but profitability may deteriorate due to raw-material prices, labor costs, construction delays, and design changes.
Nuclear reactor components, gas turbines, steam turbines, and long-term maintenance services generally have higher technological barriers and may provide more stable profitability.
Doosan Enerbility plans to increase the proportion of growth businesses such as nuclear power and gas turbines within its order backlog as follows:
- 2024: 71%
- 2025: 75%
- 2026 target: 78%
- 2030 target: 81%
If lower-margin coal-related projects decline while high-value equipment and services increase, operating profit may grow faster than revenue.
Investors should therefore monitor more than the total order backlog.
Important indicators include:
- Proportion of nuclear orders
- Proportion of gas turbine and service orders
- Proportion of combined-cycle EPC orders
- Remaining value of lower-margin legacy projects
- Expected profitability of new projects
- Rate at which the order backlog converts into revenue
The core investment thesis for Doosan Enerbility depends not only on a larger order backlog, but also on an improvement in the quality of that backlog.
7. Large Nuclear Power Plants: The Business Capable of Generating the Largest Orders
Large nuclear power projects are a core business in which Doosan Enerbility has extensive manufacturing experience and large-scale forging capabilities.
The company can manufacture reactors, steam generators, turbine generators, and other critical nuclear components.
Orders related to the Czech nuclear project contributed significantly to backlog growth in 2025.
The company is also pursuing opportunities involving additional Czech units, new domestic nuclear plants, and projects in Vietnam, Türkiye, Poland, and the United States.
The main advantage of large nuclear projects is that a single order can generate substantial revenue over a long period.
After construction, maintenance, replacement components, and generator diagnostics can also create recurring service revenue.
However, the business carries several risks:
- Changes in government policy
- Licensing delays
- Project cost increases
- Financing delays
- Changes in local political or diplomatic relationships
- Construction delays
- Local supply-chain requirements in export markets
A long period may pass between the announcement of a nuclear project and actual revenue recognition.
Investors should therefore focus on final contracts, manufacturing commencement, and construction progress rather than preliminary agreements alone.
8. SMRs: Moving from Expectations Toward Actual Manufacturing
Small modular reactors are one of Doosan Enerbility’s most important long-term growth opportunities.
The company has established partnerships with several SMR developers, including NuScale Power, X-energy, TerraPower, and Rolls-Royce SMR.
With X-energy, Doosan Enerbility signed a reservation agreement for long-lead materials required for 16 SMR modules.
A reservation agreement is a step taken before a full manufacturing contract to secure long-lead materials and production capacity.
Doosan Enerbility is also discussing the supply of major equipment and additional long-lead components for X-energy projects.
In 2026, the company was selected as a key equipment partner for Rolls-Royce SMR.
It will conduct manufacturability reviews for reactors and other major equipment intended for projects in the United Kingdom and the Czech Republic.

The positive development is that SMR projects are moving from the design stage toward execution as developers secure funding, licensing, and initial construction progress.
However, investors should avoid recognizing SMR revenue too early.
The main stages to monitor are:
- Power purchase agreements by the project owner
- Project financing
- Construction and operating licenses
- Full manufacturing contracts for Doosan Enerbility
- Procurement of long-lead materials
- Actual manufacturing progress
- Delivery and revenue recognition
SMRs offer significant long-term potential, but project delays and cancellations remain possible.
9. Gas Turbines: AI Data Centers Have Emerged as a New Source of Demand
Doosan Enerbility’s gas turbine business was one of the areas showing the most concrete progress in 2026.
During the first quarter, the company secured orders for three gas turbines for domestic combined-cycle power plants and seven gas turbines for North American data centers.
The North American contract involves the delivery of seven 380MW-class gas turbines and generators for data center power generation.
Deliveries are scheduled to begin in May 2029, with one unit supplied each month.
Including this order, Doosan Enerbility’s cumulative gas turbine orders in the United States reached 12 units.

AI data centers require large quantities of stable electricity.
In areas where grid connections are delayed or renewable energy alone cannot provide reliable power around the clock, gas-fired generation may serve as a complementary source.
Gas turbine sales also create opportunities beyond one-time equipment revenue.
After installation, the company may generate long-term service revenue from:
- Scheduled inspections
- Replacement of high-temperature components
- Performance upgrades
- Life-extension services
- Long-term parts supply agreements
- Operation and maintenance support
Doosan Enerbility aims to secure more than 100 cumulative gas turbine orders and KRW 1 trillion in annual service revenue by 2034.
These remain long-term company targets, so investors should verify actual repeat orders and service-contract execution.
10. Why Long-Term Services Matter
Power-generation gas turbines require maintenance and component replacement for several decades after installation.
Initial turbine sales generate manufacturing and installation revenue, while long-term service contracts can provide more recurring and stable earnings.
Doosan Enerbility has secured long-term service agreements for the Bundang and Eumseong combined-cycle plants.
It has also signed long-term parts supply agreements for gas turbines at Goyang Changneung and Hadong.

As the installed base of Doosan gas turbines expands, the number of units capable of generating long-term service revenue also increases.
If this business structure develops successfully, Doosan Enerbility may become less dependent on one-time project orders and gain a larger base of recurring service revenue.
Investors should monitor:
- Proportion of gas turbine orders accompanied by service contracts
- Service-contract duration
- Revenue from replacement components
- Service operating margins
- Expansion of overseas service networks
- Customer utilization rates and operating hours
11. Steam Turbines Complement the Gas Turbine Business
Combined-cycle power plants use exhaust heat from gas turbines to produce steam, which then powers steam turbines and increases overall efficiency.
A company capable of supplying both gas and steam turbines can therefore increase the value of each project.
Doosan Enerbility secured 2.2GW of steam turbine orders in the first quarter of 2026 and is targeting 3.2GW for the full year.
After receiving its first large combined-cycle steam turbine order in North America in March 2026, the company signed an additional contract to supply four steam turbines.

In the North American power market, gas turbine manufacturers frequently supply steam turbines as part of an integrated package.
As overseas gas turbine orders increase, Doosan Enerbility may also expand sales of steam turbines, generators, and long-term services.
12. Middle Eastern EPC Projects Provide a Revenue Base
Doosan Enerbility is carrying out large gas-fired combined-cycle EPC projects in Saudi Arabia, Oman, Vietnam, and other markets.
In June 2026, it signed a construction contract for the Duqm combined-cycle power plant in Oman as part of a consortium with Korea Western Power.

https://www.doosannewsroom.com/?p=51580
Electricity demand is increasing in the Middle East and Asia due to industrialization, urbanization, and data center expansion.
Large EPC projects can provide revenue over several years and create additional opportunities to supply Doosan turbines and generators.
However, EPC businesses carry several risks:
- Higher raw-material and equipment prices
- Rising local labor costs
- Construction delays
- Currency fluctuations
- Design changes
- Delayed payments from project owners
- Lower-than-expected project profitability
Even when EPC order value increases, operating-profit improvement may remain limited if construction costs rise at the same time.
13. Financial Position and Net Debt
At the end of the first quarter of 2026, net debt in the Enerbility segment stood at KRW 3.54 trillion.
This was an increase of KRW 884.2 billion from KRW 2.66 trillion at the end of 2025.
The debt-to-equity ratio was 140.7%.
On a consolidated basis, net debt was KRW 3.40 trillion, with a debt-to-equity ratio of 130.6%.
The first-quarter increase in net debt may reflect working-capital requirements, investment spending, and normal quarterly cash flow fluctuations during project execution.
Large project-based businesses sometimes receive advance payments, but significant cash must also be invested during manufacturing and construction.
An increase in orders therefore does not always result in an immediate increase in cash.
Investors should monitor:
- Operating cash flow
- Advance payments and contract liabilities
- Accounts receivable
- Inventory and contract assets
- Capital expenditure
- Net debt
- Interest expense
Even if operating profit grows, a lack of cash-flow improvement may limit growth in shareholder value.
14. Major Upside Drivers in 2026
Expansion of Large Nuclear Orders
If revenue from the Czech nuclear project expands according to plan and additional domestic or international nuclear contracts are secured, the long-term order backlog and revenue outlook may improve.
Conversion of SMR Partnerships into Manufacturing Contracts
If reservation agreements and development partnerships convert into full equipment manufacturing contracts, SMR expectations may become more concrete revenue opportunities.
Repeat Gas Turbine Orders in North America
Additional gas turbine orders from North American data centers and power producers would provide further evidence of the company’s competitiveness in overseas markets.
Expansion of Long-Term Service Revenue
As the installed base of gas turbines and nuclear equipment grows, maintenance and replacement-parts revenue may increase and reduce earnings volatility.
Improvement in Order Backlog Quality
If nuclear power, gas turbines, and other higher-margin businesses represent a larger proportion of the order backlog while lower-margin legacy projects decline, operating margins may improve.
Operating-Margin Expansion
The company’s 2026 operating-margin target for the Enerbility segment is 5.4%.
If actual profitability approaches or exceeds this target, investors may conclude that the larger order backlog is successfully converting into earnings growth.
15. Major Downside Risks
Nuclear Policy and Project Delays
Large nuclear projects are influenced by government policy, diplomatic relationships, and financing.
Contracts and construction may be delayed for years after initial project announcements.
Delayed SMR Commercialization
If SMR developers fail to secure funding or face delays in licensing and power purchase agreements, Doosan Enerbility’s manufacturing contracts may also be postponed.
Intensifying Gas Turbine Competition
The global gas turbine market includes experienced competitors such as GE Vernova, Siemens Energy, and Mitsubishi Power.
To expand overseas market share, Doosan must prove long-term operating reliability and service competitiveness.
Slower AI Data Center Investment
If investment in AI infrastructure and data center construction slows, North American turbine demand may fall below expectations.
EPC Cost Inflation
Higher raw-material and labor costs or construction delays may reduce the profitability of large projects.
Rising Net Debt
Even if orders and revenue grow, persistent increases in net debt and interest expense may limit improvement in shareholder value.
Elevated Market Expectations
When expectations for nuclear power and AI-related electricity demand are already reflected in the share price, even positive order announcements may lead to a correction if they fall short of market expectations.
16. Korea Stock AI Scenario Analysis
The following scenarios are not brokerage target prices.
They are conditional outlooks based on nuclear, SMR, and gas turbine orders, operating margins, and cash flow.
| Scenario | Key Conditions | Expected Direction |
|---|---|---|
| Bull Case | Overseas nuclear and SMR contracts expand while repeat North American gas turbine orders and profitability improve | Further valuation expansion as a core global energy infrastructure supplier |
| Base Case | Order backlog and revenue increase, but the conversion of nuclear and SMR projects and margin improvement progress gradually | Long-term growth remains intact, but the share price remains volatile around contract and earnings announcements |
| Bear Case | Nuclear and SMR projects are delayed while EPC costs, weaker turbine orders, and net debt increase simultaneously | Earnings estimates and valuation multiples may be revised lower |
Bull Case
Revenue from the Czech nuclear project expands according to schedule and additional international nuclear projects convert into final contracts.
SMR partnerships involving X-energy, Rolls-Royce, and other developers move into actual manufacturing contracts.
At the same time, repeat gas turbine orders for North American data centers and long-term service agreements are secured.
If a higher proportion of premium equipment and service revenue produces rapid margin improvement, Doosan Enerbility could be valued more like a nuclear and turbine technology company than a traditional plant-construction business.
Base Case
The order backlog continues to increase, led by nuclear power and gas turbines, but major projects convert into revenue gradually.
Revenue and operating profit increase, although quarterly performance remains sensitive to project progress and EPC costs.
SMRs continue to support the long-term growth narrative, but their immediate contribution to earnings remains limited.
Under this scenario, the share price may continue to experience significant volatility around order and earnings announcements.
Bear Case
Large nuclear and SMR projects are delayed while North American gas turbine demand slows.
If EPC project costs and net debt also increase, the company may fail to meet market expectations for earnings and cash flow despite a growing order backlog.
In that case, the market may again value Doosan Enerbility as a volatile large-project contractor rather than a high-growth energy technology company.
17. Conditions That Would Invalidate the Investment Thesis
The positive investment thesis should be reassessed if several of the following conditions occur simultaneously:
- Nuclear revenue fails to increase for an extended period despite a growing nuclear order backlog
- The Enerbility segment’s operating margin remains near 3%
- No additional overseas gas turbine orders are secured for an extended period
- Gas turbine orders do not lead to long-term service agreements
- Full SMR manufacturing contracts are repeatedly delayed
- Major SMR developers experience financing or licensing interruptions
- Significant cost overruns occur on EPC projects
- Operating cash flow continues to weaken despite a larger order backlog
- Net debt and interest expense continue to increase
- Lower-margin projects decline more slowly than expected
- Management repeatedly lowers its medium-term revenue and operating-margin targets
Investors should focus not on a single project delay, but on whether several business and financial indicators deteriorate simultaneously.
18. Key Indicators to Monitor
During Doosan Enerbility’s earnings and order announcements, investors should prioritize the following indicators:
- New orders in the Enerbility segment
- Total order backlog
- Proportion of nuclear and gas turbine orders
- Rate at which the order backlog converts into revenue
- Enerbility segment revenue
- Enerbility segment operating margin
- New large nuclear contracts and project progress
- Conversion of SMR reservation agreements into manufacturing contracts
- Additional North American gas and steam turbine orders
- Long-term gas turbine service agreements
- EPC project cost ratios
- Operating cash flow
- Net debt and interest expense
- Annual order and earnings guidance
- AI data center and global electricity infrastructure investment plans
The size of an order announcement is less important than its expected profitability and its conversion into revenue, operating profit, and cash flow.
Conclusion: Moving from Order Expectations to Earnings Confirmation
Doosan Enerbility is transforming its business around nuclear power, gas turbines, and SMRs.
Orders in the Enerbility segment more than doubled in 2025, and the order backlog exceeded KRW 24 trillion by the end of the first quarter of 2026.
The order for seven gas turbines for North American data centers, additional steam turbine contracts, the X-energy SMR material reservation agreement, and selection as a key equipment partner for Rolls-Royce SMR demonstrate that the company’s growth businesses are becoming more concrete.
However, the most important issue for investors is not the announcement of new orders alone.
The market will focus on three questions:
- Will the large order backlog convert into actual revenue and operating profit?
- Will the growing contribution from nuclear power, gas turbines, and services improve operating margins?
- Will higher investment and working-capital requirements eventually generate stronger cash flow?
Doosan Enerbility in 2026 can therefore be evaluated not simply as a nuclear theme stock, but as a potential beneficiary of expanding nuclear, SMR, and AI data center electricity infrastructure.
However, large projects remain highly sensitive to policy, contracting, construction progress, and cash flow.
Investors should focus less on short-term share-price movements and continue monitoring the Enerbility segment’s order backlog, operating margin, repeat gas turbine orders, SMR manufacturing contracts, and net debt.
