CK Infrastructure Holdings Issuer Summary

Report date: 2026-05-20
Issuer: CK Infrastructure Holdings Limited (長江基建集團有限公司; hereafter, CKI)
Ticker: CKINF / HKEX 1038 / LSE CKI
Relevant bond issuer: Cheung Kong Infrastructure Finance (BVI) Limited, with other CKI-guaranteed financing entities to be checked case by case
Bond structure reference: The principal instrument specifically reviewed in this report is the US$5bn Euro MTN Programme issued by Cheung Kong Infrastructure Finance (BVI) Limited and guaranteed by CK Infrastructure Holdings Limited. For other CKI-guaranteed bonds, the issuer, guarantor and terms need to be checked in the relevant documents on a case-by-case basis. Based on the scope reviewed in this report, parent company CK Hutchison Holdings, Power Assets Holdings, Hong Kong Electric Investments and individual investee operating companies should not be treated as general guarantors of CKI debt. For individual bonds, the negative pledge, cross default, change of control, investor put, tax provisions, listing and clearing systems, and individual ratings should be confirmed in the full Pricing Supplement and Offering Circular.

Scope note: This is the initial coverage report on CKI. CKI owns a large portfolio of regulated and contract-based infrastructure assets, but it is not a single electric utility. Accordingly, the analysis considers both the stability of essential infrastructure businesses and the structural subordination and capital allocation risk of a listed infrastructure investment holding company.

1. Business Snapshot and Recent Developments

CKI is a global infrastructure investment holding company listed in Hong Kong and dual-listed in London. It owns interests in electricity, gas, water, waste treatment, transport infrastructure and household infrastructure-related businesses through subsidiaries, associates, jointly controlled entities and its stake in Power Assets Holdings Limited (hereafter, Power Assets). Company materials show a portfolio spanning Hong Kong and mainland China, the United Kingdom, Continental Europe, Australia, New Zealand, Canada and the United States. The starting point for credit analysis is to read CKI not as a “power company” or a “Hong Kong government-related utility credit”, but as a listed holding company that aggregates dividends, equity-accounted earnings, asset disposals and external funding from regulated and contract-based infrastructure assets.

This positioning is practically important for bondholders. CKI group assets include many electricity, gas and water networks with relatively stable demand, as well as businesses with long-term contracts or established customer bases. At the same time, the repayment source for CKI-guaranteed bonds is not a direct claim on the revenues of each operating company. It depends on liquidity at CKI and group finance subsidiaries, dividends and distributions from investees, asset disposal proceeds, and refinancing capacity in bank and bond markets. Therefore, in addition to tariff frameworks and regulated asset bases, which are important in ordinary utility analysis, it is necessary to assess the distance of cash flow from the perspective of holding-company creditors, dividend restrictions at associates and jointly controlled entities, minority interests, local regulation, and ranking relative to investee debt.

Full-year 2025 results provide a sufficiently stable base for initial coverage. Profit attributable to shareholders in 2025 was HK$8.265bn, up 2% from HK$8.115bn in 2024. Funds from operations (hereafter, FFO) was HK$8.515bn, up 15% from HK$7.416bn in 2024. Cash and bank deposits were HK$7.350bn, total debt was HK$20.835bn, net debt was HK$13.485bn, and group headline net debt to net total capital was 8.9%. On the proportionate basis shown in the company presentation, net debt to net total capital was 48.5%, indicating that the debt burden including investee-level debt is considerably heavier than CKI’s headline consolidated net debt ratio.

By business contribution, most profit comes from the United Kingdom, Power Assets and Australia. Total contribution from businesses in 2025 was HK$9.770bn, comprising the United Kingdom at HK$3.983bn, Power Assets at HK$2.246bn, Australia at HK$1.784bn, Continental Europe at HK$961mn, Canada at HK$528mn, New Zealand at HK$200mn, and Hong Kong and mainland China at HK$68mn. Treasury-related activities and other activities were negative HK$1.067bn, distributions to perpetual securities were HK$438mn, resulting in final profit attributable to shareholders of HK$8.265bn. This composition shows that CKI’s profit sources are sufficiently diversified, but the quality of diversification is not uniform. Regulated infrastructure in the United Kingdom, Australia and Hong Kong power-related assets supports stability, while household services and airport parking in Canada, metering and waste in Europe, and construction materials in Hong Kong and mainland China carry more commercial volatility.

The largest development from 2025 to 20 May 2026 was the disposal of UK Power Networks (hereafter, UKPN). In February 2026, CKI, Power Assets and CK Asset agreed to sell 100% of UKPN Holdings Limited to ENGIE UK 2026 Limited. As for transaction status, the disposal was approved at a special general meeting on 27 April 2026, and completion was announced through UKPN-side RNS on 7 May 2026. CKI’s directly disposed interest was 40%, with cash consideration of GBP4.2192bn, equivalent to approximately HK$44.3bn based on the company announcement. The 100% equity consideration, including the stakes held by Power Assets and CK Asset, was GBP10.548bn. CKI stated that it expected an effective gain of approximately HK$14.5bn, including both its direct interest and the indirect impact through Power Assets. However, this HK$14.5bn is the company’s expected profit impact and is not the same as cash on hand at the CKI guarantor level, pro forma net debt, accounting gain recognition, or the actual use of proceeds.

The UKPN disposal is not simply credit-positive for CKI. Following completion, CKI has likely monetised an amount that substantially exceeds its 2025 year-end net debt of HK$13.485bn. If the proceeds are used for debt repayment or liquidity retention, short-term credit headroom would increase materially. However, the company has described the use of proceeds as future investment and acquisitions, and has not earmarked the proceeds for debt reduction. In addition, UKPN was a core regulated electricity distribution asset in the United Kingdom, and the disposal also means giving up part of a stable earnings source. Therefore, while the transaction should be recognised in credit analysis as a completed large-scale asset disposal, it should not be treated as permanent deleveraging until CKI’s pro forma cash, net debt, gain recognition, reinvestment targets, shareholder returns and M&A policy are confirmed.

Another capital recycling event was the disposal of UK Rails. In January 2026, a CK Group consortium including CKI completed the sale of Eversholt UK Rails Group and received GBP1.1bn in cash proceeds at the consortium level. UK Rails had been part of CKI’s UK portfolio through 2024, so this also demonstrates a track record of realising asset value. At the same time, the more asset disposals continue, the more future stable distribution sources may decline. CKI’s credit therefore depends not only on its ability to sell assets, but also on the risk-return profile of assets into which it reinvests after disposal.

Another important point in 2025 is the overlapping timing of regulatory resets. Regulatory period renewals and final determinations are progressing in 2025-2026 for UK water, UK gas distribution, Australian electricity and gas networks, and New Zealand electricity distribution. Based on company materials, allowed returns and revenue allowances are being revised across several assets following decisions by Ofwat, Ofgem, the Australian Energy Regulator (hereafter, AER), and the New Zealand Commerce Commission. Regulatory resets after higher interest rates and inflation can be more supportive of earnings than the low-rate regulatory periods of the past several years, but political pressure around water tariffs, energy bills, cost of living and environmental investment is also significant. Regulated infrastructure is a credit support, but regulation is not always favourable to the issuer.

Overall, CKI’s initial credit profile has two sides: “low-leverage CKI-guaranteed bonds” and “an infrastructure holding company with debt and regulatory risk at the investee level”. Group net debt at end-2025 was low, and the 2025 Annual Results Investor Presentation showed S&P A/Stable, supporting strong short- to medium-term repayment capacity. However, if one ignores proportionate leverage, capital allocation after the UKPN disposal, dependence on cash flow from associates and JVs, regulatory resets, and unverified bond terms, there is a risk of overvaluing CKI as a stable utility bond.

2. Industry Position and Franchise Strength

CKI’s franchise consists not of sales share in a single market, but of long-term interests in essential infrastructure across multiple countries, assets embedded in regulatory frameworks, capital market access, and infrastructure investment execution capability within the CK Group. Since its listing in 1996, the company has expanded its investment scope from Hong Kong and mainland China to the United Kingdom, Australia, New Zealand, Canada and Continental Europe. Its strengths as an infrastructure investment company are that demand for each business is not fully correlated with the economic cycle, revenue visibility is relatively high due to regulation and long-term contracts, and the portfolio can be reshaped through asset disposals and acquisitions.

However, CKI is not a pure regulated utility. It owns many assets with tariff regulation or capital-base returns, such as Hong Kong electricity through Power Assets, UK gas and water, and electricity distribution in Australia and New Zealand. At the same time, it also owns more commercially exposed assets, including metering and energy services such as ista, waste treatment at AVR, household equipment rental and services at Reliance Home Comfort, airport parking at Park'N Fly, and cement and concrete businesses in Hong Kong and mainland China. Therefore, CKI’s business risk is lower than that of a general corporate, but more complex than that of a single regulated electricity utility.

Geographic diversification is a credit support. In 2025 profit contribution, the United Kingdom was the largest contributor, followed by Power Assets and Australia. The portfolio combines assets with different risk characteristics: water, gas and electricity distribution in the United Kingdom; electricity and gas networks in Australia; electricity distribution and waste in New Zealand; metering and waste in Continental Europe; and household services and airport parking in Canada. This materially reduces dependence on a single country or single regulatory framework, but it also increases the number of variables to manage because each country has different regulation and currency.

At the same time, geographic diversification increases regulatory complexity. UK water is subject to Ofwat’s PR24, UK gas distribution to Ofgem’s RIIO-GD3, Australian distribution to five-year AER regulatory determinations, and New Zealand electricity distribution to the Commerce Commission’s Default Price-Quality Path. The cost of capital, efficiency targets, investment recovery, service quality, environmental and climate requirements, and customer tariff caps allowed by regulators differ by country. Investors should not stop at the simple statement that “regulated assets are stable”; they need to assess whether allowed returns have risen in each regulatory period, whether investment obligations have become heavier, and whether customer tariffs are socially acceptable.

Power Assets strengthens CKI’s franchise, but also creates structural distance. CKI is a major shareholder of Power Assets, whose profit contribution to CKI was HK$2.246bn in 2025. Power Assets is a separately listed company investing in Hong Kong power-related assets, the United Kingdom, Australia, Canada and Europe, and has a significant relationship with HKEI / HK Electric. However, returns from Power Assets’ investees first become earnings and dividends at Power Assets, and then reach CKI. HKEI or HK Electric’s regulated earnings should not be viewed as a direct repayment source for CKI-guaranteed bonds.

The relationship with CK Hutchison Holdings (hereafter, CKHH) also requires attention. CKHH is CKI’s controlling shareholder, with an approximately 75.67% profit sharing interest, and has significant influence over capital allocation, acquisitions and disposals, and governance within the CK Group. The CKHH group is a large credit with ports, retail, telecommunications, infrastructure and investments, and it underpins CKI’s market access and transaction execution capability. However, CKHH does not generally guarantee CKI debt. The existence of the parent is important in the context of capital allocation and group strategy, but should be distinguished from a legal guarantee of debt payment.

Within the industry, CKI is an Asia-origin listed infrastructure investment company with scale, track record and asset recycling capability. Regulated utility assets in the United Kingdom, Australia and Hong Kong, a long operating track record, external assessment in the A category, and access to the MTN market lower its business risk compared with similarly rated general corporates. On the other hand, compared with a pure Hong Kong electric utility or a Singapore government-linked infrastructure issuer, CKI has greater asset rotation, associate and JV complexity, parent-group transactions, overseas regulatory risk and foreign-exchange risk. This combination of utility-like characteristics and investment holding company characteristics is central to CKI’s credit analysis.

3. Segment Assessment

For CKI’s segment assessment, it is necessary to look not only at revenue, but also at profit contribution, dividend capacity, regulatory framework, capital consumption and disposability. The 2025 business contribution table is the most useful tool for understanding which regions and investees CKI depends on. The table below is organised mainly around the 2025 profit contribution shown in the company presentation.

Power Assets is an important stable earnings source for CKI, but it is a separately listed equity investment rather than a directly operated company. HKEI / HK Electric’s Scheme of Control and Hong Kong electricity tariff framework support the stability of Power Assets, but do not provide direct protection for CKI-guaranteed bonds. The United Kingdom is the largest contributing region, and after the UKPN disposal, the weight of water, gas and other energy assets will rise, making Ofwat and Ofgem regulatory decisions and dividend capacity more important.

Australia and New Zealand are centred on regulated revenues from electricity and gas networks, and AER and Commerce Commission decisions will shape medium-term cash flow. Continental Europe’s ista and AVR, and Canada’s Reliance and Park'N Fly, have recurring revenue or essential-service characteristics, but they are not regulated utilities in the tariff-regulated sense. Construction-materials businesses in Hong Kong and mainland China saw contribution fall to HK$68mn in 2025. The overall impact is small, but it illustrates that CKI is not a fully regulated utility portfolio.

For bondholders, the key regulated and contract-based assets can be simplified as follows. Figures are limited to what can be confirmed from company materials, and uncollected RAVs and detailed allowed returns remain pending items.

As this table shows, CKI’s business base is high quality but not homogeneous. The most stable assets are regulated networks, followed by contract-based and essential services, while the most volatile areas are construction materials, travel and some commercial services. Credit assessment should focus less on the simple aggregate of assets and more on earnings stability, dividend capacity, regulatory resets and the quality of the portfolio after reinvestment.

4. Financial Profile and Analysis

For CKI’s financial profile, it is more useful to focus on profit attributable to shareholders, FFO, dividends and distributions, cash, total debt and look-through leverage than on revenue and operating profit used for general corporates. This is because CKI’s profit includes a large amount of equity-accounted earnings from associates and jointly controlled entities. In the 2025 consolidated income statement, share of results of associates was HK$2.895bn and share of results of joint ventures was HK$6.127bn, meaning that most of the HK$8.843bn profit before tax came from investee earnings. This does not mean that earnings quality is weak, but those earnings must pass through a dividend or distribution process before reaching CKI in cash.

FFO in the table is a company-disclosed metric based on the Annual Report notes, calculated as net cash from operating activities plus dividends received from associates and joint ventures. The 2025 components were net cash from operating activities of HK$2.213bn, dividends from associates of HK$2.319bn, and dividends from joint ventures of HK$3.983bn. Therefore, FFO is useful as a cash-conversion metric close to the CKI guarantor, but it is not free cash flow itself and assumes the continuation of investee dividends. The proportionate net debt to net total capital ratio is a metric shown in the company presentation and is understood in this report as incorporating investee net debt in proportion to CKI’s economic interest, although the detailed formula has not been confirmed.

Headline financial risk in 2025 was low. Against net debt of HK$13.485bn, FFO was HK$8.515bn, implying simple net debt / FFO of around 1.6x. FFO relative to total debt of HK$20.835bn was also around 2.4x, which is not an excessive burden for a listed infrastructure holding company. Cash of HK$7.350bn represented approximately 35% of total debt, and given that debt due within one year was 13% of total debt, short-term liquidity headroom was substantial.

However, the analysis should not end at the group headline level. The company presentation shows proportionate net debt to net total capital of 48.5% in 2025, up from 47.0% in 2024. This means that, when debt at CKI’s infrastructure investees is included on a proportionate basis, leverage across the group’s economic interests is considerably higher. For infrastructure assets, it is common for investees to carry high debt supported by regulated revenues or long-term contracts. However, if interest rates rise, regulatory resets become unfavourable, or operating performance weakens, dividend capacity at investees falls first and then affects cash flow to CKI with a lag.

The relationship between dividends and FFO is important when assessing earnings cash conversion. CKI has increased dividend per share over a long period, and the 2025 dividend per share was HK$2.61. According to the Annual Report dividend note, the 2025 interim dividend of HK$0.73 and the proposed final dividend of HK$1.88 totalled HK$6.576bn, equivalent to approximately 80% of profit attributable to shareholders of HK$8.265bn. Dividends paid during 2025 in the cash flow statement were HK$6.526bn, in addition to HK$438mn of distributions on perpetual capital securities. This shows a shareholder-return orientation for an investment-grade infrastructure holding company. From a creditor perspective, however, it is necessary to keep assessing how FFO is allocated among dividends, perpetual distributions, reinvestment and debt repayment.

The presentation of operating cash flow also requires care. CKI’s consolidated cash flow involves not only operating cash flow from operating subsidiaries, but also dividends from associates and jointly controlled entities, investment activity, acquisitions and disposals, and borrowing and repayment. Even if profit is stable in 2025, CKI-guaranteed bond headroom will change if investees increase capex, regulators constrain dividends, or acquisitions consume cash. In this initial report, detailed CKI standalone or guarantor-level cash flow could not be sufficiently confirmed, so future MTN investment should additionally verify guarantor-level funding, bank facilities and individual debt balances.

On capital, perpetual capital securities should also be considered. Perpetual capital securities at end-2025 were HK$9.885bn and are treated closer to equity for accounting purposes. This makes net debt to net total capital look lower. At the same time, perpetual distributions are cash outflows, and call, refinancing and rating-equity-credit treatment depend on market conditions. From the perspective of senior creditors, perpetuals are likely to rank above ordinary equity but below senior debt; they demonstrate capital flexibility while also adding another layer to the funding structure.

The overall financial assessment currently provides strong support to credit quality. However, the support is not based only on the low level of CKI standalone net debt. It combines stable equity-accounted earnings, FFO, long-standing market access, low near-term maturities and asset disposal capacity. On the other hand, proportionate leverage, payout ratio, dependence on investee dividends and reinvestment after the UKPN disposal will determine future credit headroom.

5. Structural Considerations for Bondholders

For CKI bondholders, the most important issue is which entity is obligated to pay and which entities are not. This report focuses on the US$5bn Euro MTN Programme of Cheung Kong Infrastructure Finance (BVI) Limited and the CKI guarantee. In the HKEX publication announcement of June 2025, the programme issuer is Cheung Kong Infrastructure Finance (BVI) Limited, the guarantor is CK Infrastructure Holdings Limited, and the programme listing is for professional investors. The full text of the Offering Circular and all terms in each Pricing Supplement have not been fully verified in this report.

As this structure table shows, CKI’s credit is neither simply “safe because there are strong investees” nor “risky because there is investee debt”. Regulated infrastructure tends to generate stable earnings, but those earnings first pass through operating expenses, capex, taxes, local borrowings, regulatory conditions and dividend restrictions at operating companies. Holders of CKI-guaranteed bonds have claims against the CKI guarantor, but do not have direct security interests over the assets of individual operating companies.

Power Assets and HKEI require particular caution. HKEI / HK Electric is a high-quality regulated utility credit supported by electricity supply to Hong Kong Island and Lamma Island and the Scheme of Control. From CKI’s perspective, however, HKEI is an investee through Power Assets, and neither the Hong Kong government nor HK Electric pays CKI-guaranteed bonds. HKEI’s stability supports CKI’s credit through Power Assets’ equity-accounted earnings and dividends, but it is not a legal guarantee.

The same applies to parent company CKHH. CKHH controls CKI and influences group strategy, M&A, disposals and capital allocation. CKHH’s credit strength and market access are positive as an indirect background for CKI. At the same time, CKHH itself is a conglomerate holding company with ports, retail, telecommunications, infrastructure and investments, and carries separate event risks such as Panama Ports and large asset disposals. Unless CKHH directly guarantees CKI bonds, its presence should not be overvalued as legal support for debt payment.

For individual bond investment, the MTN Programme terms need to be confirmed. In general, issuer, guarantor, governing law, listing, unsecured and unsubordinated status, negative pledge, cross default, events of default, tax gross-up, early redemption, change of control, investor put, substitution, clearing and individual ratings affect investment decisions. This report is an initial issuer credit summary and is not a terms report that has verified all these points. Therefore, if the credit view in this report is used for an individual ISIN investment decision, the full Pricing Supplement and Offering Circular must be checked.

6. Capital Structure, Liquidity and Funding

CKI’s capital structure is conservative on a group headline basis. At end-2025, total debt was HK$20.835bn, cash and bank deposits were HK$7.350bn, and net debt was HK$13.485bn. Of total debt, 13% was due within one year and 87% between two and five years, so short-term maturity concentration was not significant. The presentation also shows S&P A/Stable and states that CKI has maintained an A- or above rating since 1997. These factors strongly support the short- to medium-term repayment capacity of CKI-guaranteed bonds.

Cash of HK$7.350bn at end-2025 was comfortably above a simple estimate of debt due within one year of around HK$2.7bn. This indicates headroom to absorb near-term maturities with cash on hand alone. However, the total amount of unused committed bank facilities, guarantor-level cash, cash location by currency, and fund transfer from the BVI issuer to CKI have not been confirmed in detail in this report. Therefore, the liquidity assessment is strong, but it does not constitute a definitive assessment of guarantor-level or individual issuer-level funding.

Completion of the UKPN disposal may substantially change liquidity during 2026. Cash consideration for CKI’s direct 40% stake was approximately GBP4.2192bn, or around HK$44.3bn, well above 2025 year-end net debt of HK$13.485bn. If the transaction is fully monetised at the CKI level and used for debt reduction, CKI could even have room to move into a net cash position in substance. However, the company has described the use of proceeds as future investments and acquisitions, so the disposal proceeds are likely to be used as a source of asset rotation. Therefore, the credit question is not only “whether cash came in”, but also “which assets, at what leverage, and with which regulatory, currency and political risks CKI reinvests into”.

The disposal and capital allocation events show that CKI’s capital policy has both conservative and growth-oriented characteristics.

Funding access is strong. CKI can combine the Hong Kong market, international MTN market, bank loans, perpetual securities and asset disposals. Dual listing in London also broadens the investor base and recognition. However, having access and always being able to fund at low cost are not the same. In a high-rate environment, allowed returns on regulated infrastructure assets may rise, while debt refinancing costs also increase. In particular, investee-level debt is affected at different times depending on each country’s regulatory period and interest-rate hedging.

Foreign exchange is also important. CKI reports in Hong Kong dollars, but its earnings and assets are widely diversified across GBP, AUD, NZD, CAD, EUR and other currencies. The 2025 business contribution table also shows differences between local currency basis and Hong Kong dollar basis. Currency diversification reduces Hong Kong dollar-only risk, but it also affects reported profit, dividend capacity, leverage ratios and Hong Kong dollar translation of disposal proceeds. In particular, proceeds from the disposal of UK assets and earnings from remaining UK businesses are affected by GBP/HKD movements.

The liquidity conclusion is strong, but there are many items to confirm going forward. Cash at end-2025, low near-term maturities, the A/Stable rating, and completion of the UKPN disposal support short-term repayment capacity. Constraints are post-disposal reinvestment, look-through leverage, investee dividends, perpetual distributions and individual bond terms. In particular, the 2026 interim results need to confirm which entity received the UKPN disposal proceeds and how they were reflected in cash, net debt, dividends and M&A plans.

7. Rating Agency View

The rating shown in the 2025 Annual Results Investor Presentation is S&P A / Stable. The presentation states that the S&P rating was A / Stable as of 19 February 2025 and that CKI has maintained an A- or above rating since 1997. This is an important external confirmation that CKI has maintained an upper investment-grade market assessment over a long period, but this report has not reviewed the full S&P report as of 20 May 2026.

However, this report has not confirmed S&P’s latest full rating rationale or formal rating triggers. Therefore, rather than citing the rating agency’s detailed view, it treats the company-disclosed rating as supporting information. In analytical terms, factors supporting the A category include low group headline net debt, a stable regulated and contract-based infrastructure portfolio, long-standing capital market access, FFO stability, asset disposal capacity and execution capability within the CK Group. Constraints on the rating include dependence on associates and JVs, proportionate leverage, regulatory resets, foreign exchange and interest rates, M&A and reinvestment risk, and the complexity of relationships with the parent and associates.

Capital allocation after the UKPN disposal is particularly important for rating direction. If the disposal proceeds remain in debt reduction or conservative liquidity, headroom within the S&P A rating could increase. Conversely, if proceeds are directed toward highly leveraged acquisitions, assets with high regulatory risk, or businesses with low earnings visibility, the apparent cash increase may disappear in a short period and portfolio quality may also change. Rating agencies typically focus more on post-transaction financial policy and business risk than on the gain from the transaction itself.

Typical downgrade triggers would be an increase in group headline net debt ratios, a sustained rise in proportionate leverage, lower investee dividends, creditor-unfriendly use of asset disposal proceeds, adverse regulatory decisions, higher interest burden, and weaker liquidity. Upgrade direction could be considered if lower leverage is maintained, portfolio quality remains high after reinvestment, FFO and distributable cash are stable, and regulatory resets support earnings. However, formal rating triggers are unconfirmed, and this report does not state them as rating agency views.

8. Credit Positioning

In credit positioning terms, CKI sits between a pure regulated utility and a conventional investment holding company. Compared with a single-region regulated electricity credit such as HKEI / HK Electric, CKI has much greater asset and geographic diversification and more scope for capital recycling and M&A. At the same time, it is not close to the operating cash flow of a single regulatory framework and single guarantor, as in HK Electric-guaranteed bonds, and it has substantial cash flow via associates, JVs and Power Assets. Therefore, it is most natural to treat CKI as an infrastructure holding company with low business risk but structural risk.

Compared with CKHH, CKI’s business risk is more infrastructure-oriented, and its operating base appears more stable than CKHH, which owns retail, ports, telecommunications and investment assets. CKI’s low group headline leverage is also a strength. On the other hand, CKI is a CKHH subsidiary, and asset disposals and acquisitions are determined within the broader CK Group capital allocation framework. For CKI bonds without a CKHH guarantee, it is necessary to focus on CKI’s own liquidity, guarantee structure and investee distributions.

Compared with a typical A-rated infrastructure issuer, CKI has strong monetisable assets and capital market access. The disposals of UKPN and UK Rails demonstrated that asset value is not just an accounting concept, but can be converted into cash. This is a major fundamental support. However, whether asset disposals benefit credit depends on the use of proceeds after disposal. If high-quality regulated assets are sold and the proceeds are reinvested into more opaque acquisitions, short-term liquidity may improve while long-term credit quality may decline.

Market spreads, prices, yields, OAS and same-tenor comparisons have not been checked in this report. Therefore, no market recommendation to buy, sell or hold is made. From a fundamental perspective, CKI senior guaranteed bonds can be treated as A-category credit of a high-quality infrastructure holding company, but not as pure government-guaranteed bonds or single regulated electric utility bonds. For short- to medium-term bonds, liquidity and low leverage are strong supports. For long-term bonds, the post-UKPN portfolio, regulatory resets, M&A and look-through leverage need to be reflected in pricing. For perpetuals or subordinated securities, sensitivity to calls, distribution suspension, rating equity credit and reinvestment risk is even higher.

9. Key Credit Strengths and Constraints

CKI’s first strength is diversified investment in essential infrastructure assets. Electricity, gas, water, waste, energy-related and household infrastructure services have stronger demand resilience than cyclical consumer goods or manufacturing. Many assets are supported by regulation or long-term contracts, providing earnings visibility. As a result, profit attributable to shareholders remained stable at HK$8.265bn and FFO at HK$8.515bn in 2025.

The second strength is low group headline leverage and short-term liquidity. At end-2025, net debt to net total capital was 8.9%, and net debt was only around 1.6x FFO. Debt due within one year was also 13% of total debt, limiting short-term maturity concentration. Completion of the UKPN disposal likely created a large monetisation event in 2026. This improves resilience if refinancing or M&A conditions deteriorate.

The third strength is asset disposal capacity, capital market access and CK Group execution capability. The disposals of UKPN and UK Rails showed that CKI can monetise large infrastructure assets at high values. The company-disclosed S&P A/Stable rating, long A-category track record, MTN market access and London dual listing also support the investor base and refinancing capacity.

The first constraint, however, is structural subordination. CKI-guaranteed bonds depend on cash flows that reach CKI after investee operating company debt, regulatory obligations, operating expenses, capex, taxes, minority shareholders, JV partners and local dividend restrictions. Even if consolidated and equity-accounted earnings are large, cash may not freely move to CKI at the same time.

The second constraint is proportionate leverage. CKI standalone and headline consolidated leverage is low, but proportionate net debt to net total capital reaches 48.5% when investee debt is included. High investee-level leverage is natural for regulated infrastructure, but if interest rates rise, regulation turns unfavourable, or operations weaken, investee dividend capacity can decline and affect CKI’s FFO and capital allocation.

The third constraint is regulatory and political risk. The more essential water, gas and electricity distribution services are, the more political attention they receive regarding customer tariffs, the environment, reliability of supply and cost of living. UK water, UK gas, Australian electricity, Hong Kong electricity and New Zealand distribution all follow different regulatory frameworks, and allowed returns or capex allowances may shift unfavourably for the issuer.

The fourth constraint is capital allocation risk. UKPN disposal proceeds are not earmarked for debt reduction and may be used for future investments and acquisitions. CKI has a strong investment track record, but a large acquisition at a high price, high leverage and low transparency could change the current low-leverage position in a short period. Bondholders need to focus not on the disposal gain itself, but on asset quality and financial policy after the disposal.

10. Downside Scenarios and Monitoring Triggers

CKI downside scenarios are more likely to arise from an overlap of capital allocation, regulation, investee dividends, interest rates and foreign exchange than from a sharp deterioration in a single business. The first items to monitor are cash and net debt after the UKPN disposal, then the risk of reinvestment targets, and finally investee dividends and the regulatory environment.

The most important short-term monitoring point is the 2026 interim results. These should confirm how the UKPN disposal proceeds are reflected and how cash, net debt, investment activity, dividends, perpetual securities and M&A plans have changed. If the disposal proceeds only remain temporarily in cash, short-term credit is strong. If they are quickly directed toward a large acquisition, the acquisition target’s regulatory framework, debt and dividend capacity need to be assessed. The combination that would lower the credit view is a large acquisition with debt financing, higher group headline leverage, higher proportionate leverage, lower investee dividends and questions over maintenance of A/Stable appearing at the same time. The focus should be not on any single item, but on whether use of proceeds, leverage, dividends and rating outlook deteriorate together.

The next items to monitor are regulatory decisions. UK water and gas distribution, Australian electricity and gas networks, and New Zealand electricity distribution all have medium-term earnings shaped by regulatory determinations. Water in particular has high political sensitivity around environmental investment and customer tariffs. Even if regulators allow high capex, dividend capacity does not necessarily increase if efficiency targets or customer tariff constraints are strict.

Investee dividends are also important. CKI’s earnings are recorded as equity-accounted earnings, but debt repayment requires cash. If dividends from associates and JVs decline, CKI-guaranteed bond liquidity headroom narrows even if accounting profit remains. Power Assets, dividends from UK and Australian investees, perpetual distributions and ordinary dividends need to be considered together.

11. Credit View and Monitoring Focus

CKI’s current credit strength can be assessed as a strong infrastructure holding company credit consistent with a high investment-grade level as of 20 May 2026. The near-term credit direction is stable to somewhat positive, supported by the large monetisation from completion of the UKPN disposal, but a clear improvement direction should not be asserted until the reinvestment policy for the disposal proceeds is confirmed. The probability of a rapid deterioration in the credit level or direction is currently low. However, if the disposal proceeds are directed toward high-risk, highly leveraged acquisitions while dividends from regulated assets weaken, medium-term rating and spread pressure could increase.

The credit is supported by low group headline leverage, a substantial capital base, diversified regulated and contract-based infrastructure assets, the A/Stable rating shown in the 2025 Annual Results Investor Presentation, and the ability to monetise assets through disposals. At end-2025, net debt to net total capital was 8.9%, net debt was around 1.6x FFO, and debt due within one year was 13% of total debt. The HK$44.3bn equivalent cash consideration for the UKPN disposal is substantially larger than 2025 year-end net debt and strengthens short-term financial flexibility.

On the other hand, CKI should not be treated as a simple stable utility bond. Proportionate leverage including investee-level debt is 48.5%, and the substantive debt burden exists at the operating-company level. Holders of CKI-guaranteed bonds do not have direct claims on the business cash flows of HKEI, HK Electric, Power Assets, Northumbrian Water, SA Power Networks or other investees. Repayment sources reach the guarantor through dividends, equity-accounted earnings, asset disposals and external funding, so structural subordination and cash-flow timing must always be considered.

For investment purposes, CKI’s senior guaranteed bonds benefit from strong short-term liquidity and low group leverage. Short- to medium-term bonds in particular are strongly supported by end-2025 liquidity and the potential liquidity uplift after the UKPN disposal. For long-term bonds, the remaining portfolio after UKPN, reinvestment targets, regulatory resets, look-through leverage, and capital allocation including perpetual securities and ordinary dividends become more important. Perpetuals and subordinated securities are more sensitive than senior bonds to calls, distributions, rating equity credit and market access.

The monitoring priorities are clear. First, confirm the UKPN disposal proceeds, disposal gain, cash, net debt and use of proceeds in the 2026 interim results. Second, confirm the target, price, leverage and regulatory framework of new investments and acquisitions. Third, assess how regulatory decisions by Ofwat, Ofgem, AER, the New Zealand Commerce Commission and others affect investee dividends and proportionate leverage. Fourth, monitor dividends and regulatory developments at Power Assets and HKEI/HK Electric. Fifth, confirm individual MTN terms and market spreads. If these evolve conservatively, CKI should be able to maintain its assessment as an A-category stable infrastructure holding company.

12. Short Summary & Conclusion

CK Infrastructure Holdings is a Hong Kong-listed global infrastructure investment holding company that aggregates regulated and contract-based infrastructure assets across the United Kingdom, Australia, Hong Kong, Europe, Canada, New Zealand and other markets. Low group headline leverage and the A/Stable rating shown in the 2025 Annual Results Investor Presentation strongly support the credit of senior guaranteed bonds. Completion of the UK Power Networks disposal in May 2026 may have materially increased short-term financial flexibility, but it also represents the sale of a stable earnings source, and the risk that disposal proceeds are directed toward reinvestment or M&A rather than debt reduction needs to be monitored. CKI is a high-quality infrastructure credit, but it is not a pure utility or government-guaranteed bond. It should be assessed as holding-company debt dependent on dividends and equity-accounted earnings from investees including Power Assets and HKEI, with structural subordination, proportionate leverage and regulatory resets incorporated into the credit view.
