1. Business Snapshot and Recent Developments

Huaneng Power International, Inc. (hereafter Huaneng Power International, HPI, or HNINTL) is a major listed Chinese power generation company and a core listed subsidiary of China Huaneng Group. It is not a State Grid-type regulated utility that owns transmission and distribution networks. Its main repayment sources and risks arise from the development, construction and operation of power plants, the sale of power and heat, fuel costs, average selling tariffs, generation utilisation hours, market-based power transactions, renewable-energy tariff mechanisms and capital expenditure. For bond investors, the primary question is how far the listed generation company's standalone cash flow and heavy debt and investment burden are offset by expected support from parent China Huaneng Group and the company's policy importance to China's power supply.

The company profile is large in scale. According to the 2025 annual report, controlled installed capacity was 155,869MW as of 31 December 2025, with low-carbon and clean-energy capacity accounting for 41.01%. The company owns generation assets across 26 provinces, autonomous regions and municipalities in China, has a wholly owned power generation subsidiary in Singapore, and has an investment in an operating power generation company in Pakistan. As a Chinese power generation company, it has substantial diversification by both geography and generation mix. At the same time, it is heavily affected by China's domestic power-market framework, coal prices, capacity tariffs, renewable-energy tariff reform, and province-level differences in supply-demand balance and curtailment.

Ownership structure is central to the credit analysis. In the shareholder table in the 1Q 2026 report, Huaneng International Power Development Corporation held 32.28%, China Huaneng Group Co., Ltd. held 9.91%, and China Hua Neng Group Hong Kong Limited held 3.01%; these parties are treated as concert parties under the relevant rules on acquisitions of listed companies. In its November 2025 rating action, Fitch described HPI as China Huaneng Group's 46.23%-owned flagship subsidiary and equalised HPI's rating with the parent based on strategic and operational linkages. The company-disclosed ownership ratios and Fitch's ratio may differ because of direct versus indirect holdings, aggregation scope and reference dates; here, they are used as evidence of the parent group's influence. Parent ownership, importance within a central SOE group, and the support expectations incorporated by rating agencies support HPI's credit profile, but do not constitute an explicit guarantee of individual debt by the Chinese government.

2025 was a year in which profit improved despite lower power generation volume and tariffs. In the 2025 annual report and annual results announcement, consolidated operating revenue was RMB 229.288bn, down 6.62% yoy, while net profit attributable to equity holders of the parent was RMB 14.537bn, up 42.73%. The main reason revenue declined while profit increased was that lower fuel costs and cost control more than offset the decline in domestic power sales and average tariffs. Domestic power plants' power sold in 2025 was 437.563bn kWh, down 3.39% yoy, and the average on-grid tariff including tax was RMB 477.08/MWh, down 3.48%. Meanwhile, domestic thermal power fuel cost per unit of power sold was RMB 266.88/MWh, down 11.13%.

This combination makes the credit interpretation somewhat complicated. Profit improvement is clearly positive, but it was driven largely by lower fuel costs rather than strong demand or tariffs. Therefore, it would be too strong to read the 2025 improvement as a structural margin improvement as-is. If fuel costs rise again, average tariffs fall, utilisation hours decline and the profitability of new projects weakens under market-based renewable-energy pricing, the scale of earnings improvement could narrow. On the other hand, the ability of thermal power to generate substantial earnings when coal prices fall, while at the same time expanding wind and solar and advancing the generation mix transition, demonstrates HPI's scale and operating capability.

1Q 2026 is the first data point for assessing the 2025 improvement. In the first quarterly report dated 29 April 2026, 1Q 2026 operating revenue was RMB 56.783bn, down 5.89% yoy; profit before tax was RMB 7.694bn, down 6.20%; net profit attributable to shareholders of the parent was RMB 4.484bn, down 9.83%; and operating cash flow was RMB 12.437bn, down 28.51%. The company cited the combined effect of lower domestic power generation and tariffs and lower fuel costs. 1Q 2026 is unaudited PRC GAAP and seasonal, so it should not be mechanically extrapolated to the full year. However, the decline in revenue and operating cash flow and the increase in short-term borrowings are reasons not to take comfort solely from the strong profit improvement at end-2025.

In one sentence, HPI is a "major listed Chinese power generation credit with expected parent support." On a standalone basis, it is a capital-intensive generation company covering thermal power, renewables, gas and heat supply, with earnings exposed to fuel costs, tariffs and utilisation hours, and with large investment cash outflows. In the group context, it is an important listed subsidiary of China Huaneng Group and is embedded in China's power supply and low-carbon transition. Separating these two perspectives is the analytical axis of this report.

2. Industry Position and Franchise Strength

HPI's business base is supported by China's power demand, its scale as a listed power generation company, its importance within China Huaneng Group, geographic diversification and the generation mix transition. Controlled installed capacity of 155,869MW at end-2025 and operations across 26 domestic provinces, autonomous regions and municipalities support policy importance and refinancing access. However, HPI is a power generation company, not a grid company that owns transmission and distribution networks. Fuel costs, generation utilisation hours, average on-grid tariffs, market-based power transactions, capacity tariffs, renewable-energy market prices, curtailment, subsidies and government grants, and equipment replacement directly affect operating profit and cash flow.

This distinction is the starting point of the credit analysis. State Grid and China Southern Power Grid are centred on transmission and distribution networks and regulated revenue, whereas HPI, despite its high public-service nature, has weaker stability in cost pass-through and investment recovery than grid companies. In 2025, lower unit fuel costs for domestic thermal power supported earnings, while average on-grid tariffs and power sold both declined. Therefore, HPI's franchise should be characterised as "large-scale and policy-important, but exposed to earnings volatility as a power generation company."

On the regulatory side, coal-fired power capacity tariffs may partly support recovery of fixed costs for thermal power, but they do not eliminate volatility in fuel costs, utilisation hours or market prices. For renewables, the marketisation of new-energy on-grid tariffs creates a risk that increases in wind and solar capacity will no longer necessarily translate directly into higher profit and cash flow. S&P's May 2026 materials also show both HPI's large wind and solar capacity and tariff pressure over 2026-2028.

Credit strengths are scale, expected parent support and capital-market track record. Constraints are power sold, tariffs, fuel costs, renewable-energy profitability, investment burden and short-term debt. Mixing these points creates the risk of overrating HPI as if it were China Huaneng Group itself or a grid company.

3. Segment Assessment

In assessing HPI's segments, it is necessary to separate volume and profitability by power source. In domestic power sold in 2025, coal-fired power was 340.159bn kWh, accounting for about 77.7% of the total. Combined-cycle gas was 28.930bn kWh, wind power was 40.865bn kWh, solar power was 25.881bn kWh, hydropower was 0.972bn kWh and biomass was 0.756bn kWh. Wind and solar are growing, but coal-fired power remains the core of power sales.

Coal-fired power is the centre of HPI's earnings and risks. In 2025, coal-fired power sold declined 7.89% yoy, while lower unit fuel costs for domestic thermal power supported earnings. In domestic profit before tax by power source in 1Q 2026, coal-fired power was RMB 4.341bn, up 9.01% yoy. This indicates that lower fuel costs are currently supporting thermal power profitability. However, thermal power is affected by coal prices, average tariffs, capacity tariffs, environmental costs, carbon allowances and utilisation hours. HPI's thermal power is a necessary source for stable supply, but it carries the policy burden of decarbonisation and fuel-cost risk.

Combined-cycle gas sold 28.930bn kWh, and 1Q 2026 profit before tax was RMB 0.941bn, up 24.93% yoy. Gas-fired power is important as a flexible, peak-load, urban-demand and transitional low-carbon power source, but it is affected by gas prices, power-market prices, utilisation rates, foreign exchange and fuel procurement contracts. Its environmental burden is lower than coal-fired power, but earnings volatility remains if fuel-price pass-through is insufficient.

Wind and solar are the areas that will change HPI's future corporate profile. In 2025, wind power sold was 40.865bn kWh, up 10.59%, and solar power sold was 25.881bn kWh, up 42.77%. New-energy installed capacity reached 45,687MW at end-2025, expanding substantially compared with five years earlier. This change is aligned with China's new power system and low-carbon transition, and is also consistent with the parent group's policy importance.

However, in 1Q 2026 profit before tax, wind power was RMB 1.808bn, down 19.70%, and solar power was RMB 0.233bn, down 58.67%. Excessive conclusions should not be drawn from quarterly data, but this shows that renewable-energy capacity growth does not always translate directly into profit growth. Renewable-energy tariff marketisation, subsidies and subsidy receivables, curtailment, utilisation hours, construction costs, grid connection costs, land and sea-area use, and maintenance costs drive profitability. From a credit perspective, the increase in the renewable-energy share should not be read as simply positive; installed capacity, power generation, average prices, profit before tax, investment amount and debt growth need to be assessed together.

Overseas operations provide both diversification and complexity. Tuas Power in Singapore is a wholly owned subsidiary of HPI, and the company also has investments in Pakistan. Overseas operations provide earnings sources that are not dependent only on China's domestic framework, but they involve fuel procurement, power markets, foreign exchange, derivatives and local regulation. They should therefore be treated as a supplementary diversification benefit in credit assessment.

This report has not been able to sufficiently extract actual capacity-tariff receipts by power source, utilisation hours by plant or region, renewable-energy curtailment, or details of subsidies and subsidy receivables. Therefore, the profitability of renewables and support from capacity tariffs are assessed only directionally, and quantitative confirmation is left for the next update.

What should be read from this segment structure is that HPI's credit profile sits between "recovery in thermal profitability" and "expansion of renewable-energy investment." Thermal power supports near-term cash flow, while renewables support long-term policy alignment. However, thermal power carries decarbonisation, fuel and tariff risks, while renewables carry marketisation, utilisation-hour and investment-return risks. In credit assessment, neither should be read as simply positive or negative; capital allocation and debt burden need to be assessed together.

4. Financial Profile and Analysis

HPI's financial profile has clearly recovered since 2023 after the loss-making phase in 2021 and 2022. On an IFRS basis, operating revenue peaked at RMB 254.397bn in 2023, then declined to RMB 245.551bn in 2024 and RMB 229.288bn in 2025. By contrast, profit before tax increased from RMB 12.477bn in 2023 to RMB 17.821bn in 2024 and RMB 23.533bn in 2025. Profit attributable to shareholders of the parent also improved from RMB 8.357bn in 2023 to RMB 10.185bn in 2024 and RMB 14.537bn in 2025. Because revenue declined and profit increased at the same time, the analytical focus is not volume growth but fuel costs, tariffs, business mix, impairments, cost control and finance costs.

The largest support for 2025 earnings improvement was lower fuel costs. In the IFRS income statement, fuel costs declined substantially from RMB 142.115bn in 2024 to RMB 119.666bn in 2025. Purchased power costs also declined. Meanwhile, depreciation, labour costs and research and development expenses increased, and fixed costs are heavy for this capital-intensive business. The earnings improvement shows that HPI has a strong earnings base, but whether it can maintain the same profit level if fuel costs rise again is a separate question.

Cash flow both supports the credit profile and highlights the weight of the investment burden. Operating cash flow in 2025 was RMB 67.213bn, a large improvement from RMB 50.530bn in 2024. Investing cash flow was an outflow of RMB 57.292bn, lighter than the RMB 61.727bn outflow in 2024. The simplified FCF used in this report is an approximate figure calculated as operating cash flow plus investing cash flow, and is not a strict post-capex free cash flow measure. This simplified FCF was about RMB -11.197bn in 2024 and about RMB +9.921bn in 2025, indicating that the company was broadly able to cover investment outflows with internal cash flow in 2025.

However, this improvement should not be overestimated. HPI continues to make large capital investments. Purchases of property, plant and equipment and similar assets were RMB 58.326bn in 2025, and the company requires funding for new-energy facilities, new projects, thermal-power retrofits, environmental measures, and overseas and subsidiary investments. In 1Q 2026 as well, purchases of fixed assets, intangible assets and other long-term assets were RMB 9.154bn, and investing cash flow was an outflow of RMB 9.071bn. The power-source transition is a long-term credit support, but over the short to medium term it increases debt and refinancing needs.

The balance sheet remains heavy even after earnings improvement. On an IFRS basis, total assets were RMB 619.678bn, total liabilities RMB 400.140bn and total equity RMB 219.538bn at end-2025. Total liabilities / total equity was about 1.82x, little changed from about 1.83x in 2024. Cash and bank balances at end-2025 were RMB 19.456bn, thin relative to short-term interest-bearing debt consisting of short-term borrowings of RMB 61.932bn, short-term bonds of RMB 11.531bn, long-term borrowings due within one year of RMB 29.320bn, and long-term bonds due within one year of RMB 2.005bn. This indicates that HPI is a refinancing-based issuer that assumes normal-course access to banks and bond markets.

Under PRC GAAP in 1Q 2026, short-term borrowings increased from RMB 61.932bn at end-2025 to RMB 75.933bn at end-March 2026. Non-current liabilities due within one year were RMB 29.522bn, long-term borrowings were RMB 159.130bn, and bonds payable were RMB 49.939bn. Cash increased to RMB 21.735bn, but remained far below the combined amount of short-term borrowings and liabilities due within one year. This does not immediately imply a liquidity crisis, but it reconfirms that expected parent support, domestic bank relationships, bond-market access and rating maintenance are central to the credit profile.

Note: FY2021-FY2025 in the table above are IFRS consolidated figures based on annual reports. Unless otherwise stated, amounts are in RMB bn, and ratios calculated in this report are approximate.

The trend from 2021 to 2025 shows not so much that HPI is weak under stress, but that a power generation company's earnings are strongly affected by fuel costs and tariff mechanisms. 2021 and 2022 were loss-making, and the company returned to profit from 2023. This means that even with government-related status and parent support, the standalone generation business cannot avoid earnings volatility. On the other hand, the fact that HPI maintained capital-market access and expected group support through the loss-making period, and recovered profit and operating cash flow in 2025, demonstrates credit resilience.

1Q 2026 should not be compared mechanically in the same table as annual data because the accounting standards and periods differ. It is unaudited PRC GAAP, covers one quarter, and is affected by seasonality, Chinese New Year, the heating season, fuel inventory and receivables collection. However, the yoy declines in operating revenue, net profit attributable to shareholders of the parent and operating cash flow, and the increase in short-term borrowings, indicate that the 2025 profit improvement may not continue in a straight line.

Note: The 1Q 2026 table is unaudited PRC GAAP. Comparative figures for income statement and cash flow items are prior-year period figures, while comparative figures for balance-sheet items are end-2025 PRC GAAP figures; presentation is not fully identical to the annual-report IFRS table.

The financial conclusion is that, on a standalone basis, HPI is "improving, but remains highly leveraged and refinancing-dependent." Operating cash flow in 2025 was strong, and simplified FCF turned positive, so credit quality has clearly improved from the 2021-2022 loss-making period. However, cash is thin compared with short-term interest-bearing debt, total liabilities exceed RMB 400bn, and capital expenditure continues. Therefore, it is difficult to explain HPI as a high investment-grade credit based solely on standalone financials; expected parent support and domestic funding access need to be viewed as essential complementary factors.

5. Structural Considerations for Bondholders

For HPI bondholders, the most important point is not to confuse the support framework with legal claims. HPI is a core listed power generation company within China Huaneng Group, and the ratings from Fitch and S&P incorporate parent and government-related considerations to a significant degree. However, this does not mean that individual bonds have a direct claim on the Chinese government.

There are four layers to assess. The first is HPI's own operating cash flow, cash, bank borrowings and bond-market access. The second is expected parent support from China Huaneng Group. The third is policy importance as a central SOE power generation group. The fourth is the guarantee, security, ranking, covenants and governing law of each individual bond. This report has not confirmed the detailed terms of individual bonds, and therefore is limited to an issuer-credit assessment.

Its status as a listed subsidiary is also important. HPI has minority shareholders and non-controlling interests. Of IFRS-basis 2025 net profit of RMB 19.530bn, profit attributable to shareholders of the parent was RMB 14.537bn. Because consolidated cash flow does not all freely flow to bondholders, HNINTL bonds must be assessed by confirming the issuer, currency, governing law and guarantee structure individually.

6. Capital Structure, Liquidity and Funding

HPI's capital structure supports long-term capital investment with borrowings, bonds and other capital instruments. At end-2025 under IFRS, total interest-bearing debt was an estimated RMB 321.311bn in this report, and net interest-bearing debt was RMB 301.856bn. A large portion of total liabilities of RMB 400.140bn is financial debt that is important for repayment and refinancing analysis.

Liquidity is supported by operating cash flow, access to bank and bond markets, and expected parent support. Operating cash flow was strong at RMB 67.213bn in 2025, but declined 28.51% yoy in 1Q 2026 and is affected by changes in tariffs, generation volume and receivables collection. HPI is listed in Hong Kong and Shanghai, and its normal-course refinancing capacity appears reasonably strong. However, unused committed lines, debt by currency and a detailed maturity profile have not been confirmed.

Liquidity constraints are thin cash balances, short-term liabilities and the investment burden. Cash of RMB 19.456bn at end-2025 was far below short-term borrowings, short-term bonds, and borrowings and bonds due within one year. Investing cash flow outflow was also RMB 57.292bn in 2025. As long as new-energy investment and thermal-power retrofits continue, the balance between growth investment and debt control will be a monitoring point.

Note: Total interest-bearing debt is an estimate in this report, calculated as short-term borrowings, short-term bonds, borrowings and bonds due within one year, long-term borrowings, bonds payable and lease liabilities. For 1Q 2026, because the figures are unaudited PRC GAAP and some items such as short-term bonds are presented differently from the IFRS annual report, the amount is shown as "at least." This is not a covenant calculation, but a liquidity screen.

HPI's liquidity assessment looks weak if one focuses only on cash / short-term debt, but when funding access as a listed subsidiary of a government-related power generation group is included, it is natural to view normal-course refinancing resilience as reasonably strong. However, this assessment assumes market access, and does not mean that standalone cash can absorb short-term debt. Until unused bank lines, the maturity ladder, debt by currency and guarantee structure are confirmed, liquidity should not be overstated as "sufficient."

7. Rating Agency View

The rating-agency view indicates that HPI's credit strength is supported not only by standalone financials but also to a significant degree by parent and government-related factors. In November 2025, Fitch affirmed the Long-Term Foreign-Currency Issuer Default Ratings of China Huaneng Group and HPI at A-, with a Stable Outlook. For HPI, Fitch described it as China Huaneng Group's 46.23%-owned flagship subsidiary, assessed strategic and operational support incentives as high and legal incentives as moderate, and rated it at the same level as the parent.

The shareholder ratios disclosed by the company show the direct holdings of Huaneng International Power Development Corporation, China Huaneng Group and China Hua Neng Group Hong Kong, as well as their concert-party relationship. Fitch's 46.23% is understood as the rating-analysis aggregation of the parent group's ownership and control relationship. Both indicate "parent influence," but the scope of presentation is not identical.

Under Fitch's view, HPI's credit strength depends not only on its earnings capacity as a standalone power generation company, but also on the probability of parent support. This has two implications for investors. First, the parent link is an important support for credit quality, and assessing HPI only by standalone leverage could be overly conservative. Second, the parent link is not the same as an explicit guarantee; it is an assessment based on support incentives and rating criteria. If the parent's credit outlook, HPI's strategic importance, ownership ratio, business linkages or legal relationship changes, the rating treatment could also change.

S&P Global Ratings, in its May 2026 materials on China's energy transition, shows HPI at A / Stable and its stand-alone credit profile at bb+. The table in that material shows HPI's 2025 wind and solar capacity at 45.7GW, the share of total capacity at 29%, an expected 15.1% decline in wind and solar tariffs over 2026-2028, FFO/debt of 9-10% and FFO interest coverage of 3.5-4.0x. This indicates that while the post-support rating is high, the standalone credit profile is constrained as a highly leveraged power generation company.

The important point in the rating-agency view is the gap between HPI's standalone credit strength and its post-support credit strength. On a standalone basis, power demand, generation capacity scale, operating cash flow, lower fuel costs and renewable-energy investment are supports, while short-term borrowings, large investment, thermal-power dependence, renewable-energy marketisation, tariff decline and the parent / minority shareholder structure are constraints. On a post-support basis, parent support from China Huaneng Group, policy importance as a central SOE power generation group, and its role in China's power supply lift the rating.

The rating-agency view confirms that HPI's high external rating incorporates not only standalone financials but also parent and government-related support. Investors need to assess not only the rating level, but also the nature of support, the parent's credit profile, individual bond terms and the direction of standalone operating cash flow.

8. Credit Positioning

HPI's relative positioning is that of a "power generation credit incorporating parent and central SOE support." Compared with grid companies, it is more exposed to fuel costs, tariffs, utilisation hours and investment burden, but compared with general private power generation companies, it has stronger expected parent support and policy importance. It is a separate legal entity from China Huaneng Group itself, and should be viewed as a listed subsidiary whose credit is supplemented by expected parent support, not as the parent itself.

When comparing it with other central SOE-affiliated power generation companies, the comparison points are thermal-power dependence, renewable-energy share, fuel-cost sensitivity, power-market liberalisation, parent support, debt level, FFO/debt and individual bond guarantees. HPI has strong scale and support expectations, but on a standalone basis high leverage and investment burden are constraints. S&P's presentation of a bb+ SACP succinctly shows the gap between the post-support rating and standalone credit strength.

This report has not checked market spreads, OAS, latest prices or same-tenor bond comparisons, and therefore does not assess investment attractiveness or relative value. From a credit perspective, HPI has strong post-support credit quality, but not stability comparable to a grid company. When assessing market prices, it is necessary to check whether the volatility as a power generation company and the guarantee, liquidity, issuer, currency and maturity of individual bonds are sufficiently reflected in spreads.

In credit positioning terms, HPI is an issuer that is "strong on a post-support basis, but constrained by the power generation market and investment burden on a standalone basis." Within the scope of this report, the analysis is limited to setting out the credit foundation, with market-price-based investment judgment left as an unverified item.

9. Key Credit Strengths and Constraints

HPI's credit supports are its strong ties with parent China Huaneng Group, controlled capacity of 155,869MW and geographic diversification, improvement in profit and operating cash flow in 2025, and the transition to low-carbon power sources. Expected parent support, in particular, is the central factor offsetting HPI's high standalone debt and short-term refinancing burden.

Constraints are the size of debt, thin cash, earnings volatility as a power generation company, investment burden, and the distance between support and individual bond guarantees. 2025 improved because of lower fuel costs, but in 1Q 2026 revenue, profit and operating cash flow declined yoy. Even if issuer credit is supplemented by support, the issuer, guarantee, ranking, security, covenants and governing law of each individual bond need to be checked separately.

10. Downside Scenarios and Monitoring Triggers

HPI's downside is likely to appear through a combination of worsening fuel costs, tariffs and utilisation hours, declining returns on renewable-energy investment, deterioration in refinancing conditions, reassessment of expected parent support, and structural issues in individual bonds. Because lower fuel costs supported earnings in 2025, a reversal in fuel costs would pressure operating profit and operating cash flow. Even if capacity tariffs partly support fixed-cost recovery, they cannot fully offset deterioration in fuel costs and utilisation hours.

For renewables, credit improvement should not be judged only by the increase in wind and solar capacity. In 1Q 2026 domestic profit before tax by power source, wind and solar declined yoy. If lower tariffs on new projects, lower utilisation hours, curtailment and delayed subsidy collection overlap, capacity may increase without improving credit metrics.

On liquidity, HPI is not structured to absorb short-term debt with cash, and it depends on bank borrowings and the bond market. In normal times, expected parent support and business scale support refinancing. However, if domestic interest rates rise, the bond market becomes risk-averse, or the parent or Chinese sovereign outlook deteriorates, funding cost and tenor would come under pressure. In addition, for subsidiaries, overseas SPVs and unguaranteed bonds, even if the issuer credit is the same, guarantee, ranking, governing law and covenants can change price volatility and recovery prospects.

The most important item to monitor for HPI is the 2026 interim report. In 1Q 2026, revenue, profit and operating cash flow declined yoy, but a single quarter has strong seasonality. The first major confirmation point for whether the 2025 improvement can be sustained will be how power generation, average tariffs, fuel costs, wind and solar profit, operating cash flow, short-term borrowings and investing cash flow look at the half-year stage.

11. Credit View and Monitoring Focus

HPI's current credit strength can be viewed as that of a highly leveraged, capital-intensive power generation company on a standalone basis, and as a power generation credit incorporating parent and central SOE support on a post-support basis. The direction of credit quality, viewed only from the 2025 annual report, points to improvement, but because revenue, profit and operating cash flow declined in 1Q 2026, this report views the company as being in a phase of confirming stability after moderate improvement. The probability of a rapid change in credit level or direction is not high in normal times, but if fuel costs, tariffs, renewable-energy profitability, refinancing markets and the assessment of parent support deteriorate simultaneously, the view needs to be reassessed promptly.

The central credit view in this report is to position HPI as a "major listed Chinese power generation credit strongly supported by expected parent support." Installed generation scale, its position as a listed subsidiary of China Huaneng Group, the recovery in profit and operating cash flow in 2025, and access to domestic and overseas capital markets support issuer credit. Fitch and S&P rating materials also show that HPI's external credit strength is supported not only by the financial profile of a standalone power generation company but also by parent and government-related factors.

At the same time, standalone financial constraints are significant. Total liabilities exceed RMB 400bn, short-term borrowings are high, and cash is thin relative to short-term interest-bearing debt. Operating cash flow improved in 2025 and simplified FCF turned positive, but this was driven largely by lower fuel costs. In 1Q 2026, revenue, profit and operating cash flow declined yoy, and short-term borrowings increased. Therefore, it is risky to read HPI as "support means standalone financials do not matter."

For investors, the most important practical point is to separate issuer credit from individual bond structure. HPI's own credit quality should be assessed as a combination of expected parent support and standalone operating cash flow. The risk of individual bonds differs by issuer, guarantee, security, ranking, cross-default, governing law, maturity and liquidity. Chinese government ownership and the central SOE context are strong supports, but they do not mean that the Chinese government guarantees individual debts. Expected parent support, a parent guarantee, an HPI guarantee and a government guarantee need to be clearly distinguished.

The materials needed to judge the direction of issuer-level credit are broadly available. The 2025 annual report and 1Q 2026 confirm both earnings recovery and near-term deceleration, and rating-agency materials also confirm the gap between post-support rating and standalone credit strength. However, individual bond holding or purchase decisions require confirmation of terms, guarantee, ranking, liquidity, maturity, currency, spread and same-tenor comparisons. This report has not checked live spreads, OAS or prices, and therefore does not assess relative value.

In future monitoring, priority should be given to 2026 interim power generation, average on-grid tariffs, domestic thermal fuel costs, wind and solar profit, operating cash flow, investing cash flow, short-term borrowings, redemption of other capital instruments, and the views of the parent and rating agencies. The key point is whether the 2025 profit improvement is becoming a durable improvement in the generation portfolio's earnings power, rather than being driven only by lower fuel costs. Conversely, if tariff declines and lower utilisation hours continue, renewable-energy profit falls, and short-term borrowings keep increasing, then even if the post-support rating remains stable, the relative value and holding policy for individual bonds should be reviewed cautiously.

12. Short Summary & Conclusion

Huaneng Power International is one of China's largest listed power generation companies, and is a power generation credit strongly supported by expected parent support as a core listed subsidiary of China Huaneng Group. In 2025, profit and operating cash flow improved on the back of lower fuel costs, while in 1Q 2026 revenue, profit and operating cash flow declined yoy, making it necessary to continue monitoring power generation volume, tariffs, renewable-energy profitability and short-term borrowings. In credit assessment, it is important to clearly separate HPI's own repayment capacity, parent support from China Huaneng Group, Chinese government-related status and the legal protections of individual bonds.
