1. Business Snapshot and Recent Developments

Airport Authority Hong Kong (“AAHK”) is the operator and developer of Hong Kong International Airport (“HKIA”), which is 100% owned by the Hong Kong Government. It is not the Hong Kong Government itself, but a statutory body corporate established under the Airport Authority Ordinance (Cap. 483), and should be viewed as a government-related infrastructure issuer operating Hong Kong’s international airport. It is not an airline, an airport project SPV, or direct debt of the Hong Kong Government. For bond investors, the central question is how far HKIA’s near-irreplaceable role as Hong Kong’s sole core international airport and the expectation of government support can absorb the increase in borrowings after the Three-runway System (“3RS”), continuing investment including T2 and SKYTOPIA, the cyclicality of air traffic demand, and the limits of legal protection as an unguaranteed bond issuer.

HKIA provides Hong Kong’s external connectivity in both passenger and cargo traffic. In FY2024/25, passenger throughput was 54.9 million, cargo and airmail throughput was 5.0 million tonnes, and aircraft movements were 373,050, each recording double-digit year-on-year growth. In calendar 2025, passenger throughput recovered to 61.0 million, cargo throughput to 5.07 million tonnes, and aircraft movements to 394,730. According to ACI’s 2025 data announced in April 2026, HKIA was the world’s busiest cargo airport. In March 2026 alone, passenger throughput was 5.74 million and aircraft movements were 34,100; for 1Q 2026, passenger throughput was 16.67 million, while rolling 12-month passenger throughput was 63.05 million. On the demand side, HKIA has moved from the post-pandemic recovery phase into a phase of capacity expansion through 3RS, Greater Bay Area (“GBA”) connectivity, and recovery in transfer traffic.

Financially, however, the profile is one in which “operating capacity has recovered with demand, but borrowings have increased materially.” FY2024/25 revenue was HK$16.4bn, EBITDA was HK$7.4bn, and profit attributable to the ordinary shareholder was HK$2.5bn, improving from FY2023/24. AAHK declared a dividend of HK$1.3bn to the Hong Kong Government, the first since FY2014/15. This indicates that earnings, which had long been retained to fund 3RS, have begun to return to a more normal capital policy to some extent. However, total borrowings at the same fiscal year-end were HK$162.2bn, total borrowings to capital was 64%, and net borrowings to net capital had risen to 54%. Demand recovery is a clear support, but the debt-funded nature of 3RS investment has also progressed, and credit analysis needs to monitor not only passenger throughput but also the deleveraging path.

The first half of FY2025/26 requires a more careful reading. For the six months ended 30 September 2025, revenue increased year-on-year to HK$8.84bn, but operating expenses, depreciation, and finance costs weighed on earnings, and profit for the period was HK$1.28bn, below HK$1.56bn in the prior-year period. Operating cash flow was HK$3.42bn, capital expenditure was HK$8.57bn, repayment of borrowings was HK$18.24bn, and dividend paid was HK$1.3bn. Cash and bank balances at period-end were HK$29.04bn, while total interest-bearing debt was HK$144.14bn. Borrowings had declined from the FY2024/25 year-end, but capital expenditure commitments remained at HK$44.59bn. Therefore, 1H FY2025/26 should be viewed less as credit deterioration and more as a period in which post-3RS funding, repayment, and investment rotation appeared in the financial statements.

The latest capital markets event is the HK$19.0bn Regulation S senior notes offering priced on 28 April 2026 and listed in May 2026. The transaction comprised HK$10.0bn of 2.90% notes due 2029, HK$6.5bn of 2.97% notes due 2031, and HK$2.5bn of 3.38% notes due 2036. AAHK stated that the proceeds would be used for refinancing existing debt, capital expenditure, and general corporate purposes. The issue size was large, but the peak orderbook exceeded HK$55bn, and S&P assigned an expected rating of AA+. The transaction demonstrates that AAHK can use its high rating and the depth of the Hong Kong dollar market to refinance debt, while also confirming that capital markets access remains central to the credit after 3RS.

The most relevant recent operational event to monitor as of 20 May 2026 is Terminal 2 (“T2”). The T2 Coach Hall commenced early operations in September 2025, but T2’s passenger departure facilities are scheduled to commence operation on 27 May 2026 and had not yet opened as of this report date. On 14 May 2026, a full-scale trial involving more than 1,100 participants was conducted, and AAHK indicated that it expects to handle around 8 million passengers in the first year of operation. This can support earnings capacity and customer experience, but it also entails execution risks related to transition, initial operations, airline relocation, passenger flows, and ramp-up of commercial facilities. T2 should not be treated as an asset whose revenue contribution is already assured, but as an asset that is now moving into operation to monetise post-3RS capacity.

2. Government Linkage, Legal Mandate and Policy Role

To understand AAHK’s credit quality, the relationship with the government needs to be separated into “ownership,” “statutory mandate,” “control,” “financial support,” and “guarantee of individual bonds.” AAHK is 100% owned by the Hong Kong Government, but bondholders do not have a direct claim against the Hong Kong Government. Support expectations as a government-related issuer are strong, but treating the bonds as government-guaranteed debt would understate credit risk. The HKAA credit starts with holding these two points simultaneously.

Institutionally, AAHK is responsible for providing, operating, developing, and maintaining Hong Kong’s international airport. The Offering Circular explains that AAHK’s principal functions are to provide, operate, develop, and maintain an airport for civil aviation at and around Chek Lap Kok. Under the Ordinance, AAHK is required to conduct its business according to prudent commercial principles, taking into account safety, security, economy, and operational efficiency, and to ensure, as far as practicable, that revenue is sufficient to meet expenditure over each year and from year to year. This provision indicates that the government gives AAHK commercial autonomy, while also confirming that airport operations are a public mandate.

The government linkage operates through multiple channels. First, the Hong Kong Government owns 100% of the capital and has strong institutional involvement in AAHK’s board and management. Second, HKIA is highly important to Hong Kong’s policy objectives as an international aviation hub, cargo hub, GBA connector, and tourism, trade, and financial centre. Third, the Hong Kong Government is in a position to support AAHK’s demand base through air traffic rights, transport infrastructure, GBA integration, and related policies including T2 and Airport City. Fourth, S&P’s AA+ rating and the acceptance of AAHK in the Hong Kong dollar bond market demonstrate that AAHK has strong market access backed by its government-related status.

However, government linkage is not only a credit enhancement. The government can influence AAHK’s activities, airport charges, capital policy, dividends, and the scope of airport-related activities. AAHK’s declaration of a HK$1.3bn dividend in FY2024/25 is evidence of financial recovery, but from creditors’ perspective it is also a point to monitor in assessing the pace of retained earnings and deleveraging. If the government prioritises the public nature of the airport, tariff levels, regional development, GBA connectivity, and tourism promotion, investment and policy mandates may be prioritised over short-term debt reduction. Government ownership is therefore a strong support, but also a source of policy intervention and capital-policy constraints.

The absence of an explicit guarantee is a central point throughout this report. The May 2026 Supplemental Offering Circular states that the HK$19bn notes are direct, unconditional, unsubordinated, and unsecured obligations of AAHK and rank at least pari passu with its other unsecured obligations. This is a strong senior unsecured structure at the issuer level. At the same time, the risk factors in the same disclosure framework explicitly state that the Hong Kong Government does not guarantee the bonds and has no statutory or other obligation to provide direct or indirect financial support to repay AAHK’s outstanding debt. Government ownership and government guarantee must be separated in investment analysis.

AAHK’s credit quality is therefore best viewed in three layers. The first layer is the stand-alone cash flow of the airport operator, determined by passengers, cargo, commercial income, charges, the Airport Construction Fee, capital expenditure, and borrowing burden. The second layer is the likelihood of support arising from 100% Hong Kong Government ownership and policy importance, which has a major effect on ratings and market access. The third layer is the legal terms of each bond, where guarantee, ranking, covenants, cross-default, tax, governing law, currency, and hedging determine actual recovery risk. As this is an issuer report, analysis of individual bond terms is limited, but the absence of a government guarantee is central to the issuer view.

3. Industry Position and Franchise Strength

HKIA’s franchise should be assessed not simply by airport operating efficiency, but by the difficulty of substituting its role in Hong Kong’s external connectivity. Hong Kong is an open, city-state-like economy, and its aviation network is highly important for passengers, business, tourism, international finance, people flows, air cargo, cross-border e-commerce, and high-value logistics. Ports, roads, and railways are also important, but airports have limited substitutability for long-haul passengers and time-sensitive cargo. A shutdown or funding disruption at HKIA would go beyond AAHK as a stand-alone entity and affect Hong Kong’s function as an international hub.

The passenger franchise has moved from recovery to capacity expansion. FY2024/25 passenger throughput of 54.9 million represented a 21.6% year-on-year increase, while calendar 2025 passenger throughput of 61.0 million increased by a further 15%. In 1Q 2026, passenger throughput was 16.67 million, up 14.3% year-on-year, while March alone recorded 5.74 million passengers, up 19.6%. Growth was driven by visitors to Hong Kong, transfer and transit passengers, and route recovery to Southeast Asia, Mainland China, Europe, and other markets. In OAG’s April 2026 international passenger route rankings, routes connecting Hong Kong with Taipei, Bangkok, Manila, and Seoul Incheon ranked highly. This indicates that HKIA’s network value is not limited to simple origin-and-destination demand in Hong Kong, but includes regional transfer traffic and GBA connectivity.

The cargo franchise is a major differentiating factor for the HKAA credit. Cargo throughput in 2025 was 5.07 million tonnes, making HKIA the world’s busiest cargo airport based on ACI data. HKIA has held the world’s top cargo ranking 15 times since 2010, indicating not a one-year recovery but a long-term position as a cargo hub. Cargo is more sensitive than passenger traffic to economic conditions, trade tensions, and inventory cycles, but Hong Kong’s strengths extend beyond tonnage to high-value cargo, e-commerce fulfilment, cross-boundary transshipment, Dongguan Logistics Park, the Air-Land Fresh Lane, and the Cargo Data Platform, supported by processes and the GBA hinterland.

Passenger and cargo traffic have different credit implications. Passenger demand affects airport charges, security charges, commercial retail, advertising, food and beverage, parking, and utilisation of terminal commercial facilities. Higher passenger throughput can broaden revenue materially, but it is affected by airline flight frequencies, visitor demand, household and business spending, regional competition, air traffic rights, and geopolitical events. Cargo demand supports handling, logistics facilities, airside support, GBA connectivity, and use of warehouse and digital platforms, but is strongly influenced by the regional composition of imports and exports and the global trade cycle. In March 2026, passenger traffic was strong, while cargo was down 4.4% year-on-year, mainly due to a sharp decline in exports to the Middle East. Passenger recovery and the world-leading cargo position should therefore not be treated as a single, uniform strength; volatility needs to be assessed by revenue source.

3RS raises the ceiling of the franchise, but does not automatically imply short-term credit improvement. 3RS was commissioned on 28 November 2024, and HKIA’s long-term target capacity is 120 million passengers and 10 million tonnes of cargo. This investment is essential to preserving Hong Kong’s hub function and reduces the risk that capacity constraints cap demand recovery. However, capacity becomes cash flow only when it is used. Without T2 departure facilities, the T2 Concourse, Airport City, SKYTOPIA, transport connectivity, airline attraction, and expanded route rights, the capital cost of 3RS will not be fully recovered.

4. Segment Assessment

AAHK’s revenue structure combines aeronautical income, passenger and commercial income, airport-related services, exhibitions, property and adjacent development, and cargo and logistics-related income. In the financial statements, revenue is split into airfield income, security charges, aviation security services, airside support services franchises, retail licences and advertising, other terminal commercial income, properties, conferences and exhibitions, and other income. Credit analysis should consider not only revenue composition, but also how each revenue source is linked to passenger throughput, cargo volume, aircraft movements, commercial spending, regulated or policy-related charges, and capital expenditure.

Aeronautical income is the most fundamental repayment source of the airport franchise. In FY2024/25, airfield income was HK$4.73bn, security charges were HK$1.53bn, aviation security services were HK$0.46bn, and airside support services franchises were HK$2.76bn. In 1H FY2025/26, airfield income was HK$2.46bn, security charges were HK$0.98bn, aviation security services were HK$0.25bn, and airside support services franchises were HK$1.39bn. These items are relatively directly linked to passenger throughput, aircraft movements, airport charges, and airline flight frequencies. Demand recovery feeds through most directly to these revenues, but they are also affected by airport charging policy, which needs to take account of airlines’ earnings environment and tariff competition.

Retail, advertising, and terminal commercial income are indicators of the quality of passenger recovery. FY2024/25 retail licences and advertising income was HK$4.67bn, while other terminal commercial income was HK$0.95bn, both improving materially from the prior year. In 1H FY2025/26, these revenues were HK$2.47bn and HK$0.54bn, respectively. Commercial income depends not only on passenger throughput, but also on the mix of visitors to Hong Kong, transfer passengers, airline route composition, duty-free and retail spending, terminal dwell time, and the ramp-up of T2 commercial facilities. Passenger recovery therefore does not necessarily convert directly into commercial margins. The passenger mix and spending behaviour of Mainland China, Southeast Asia, and long-haul routes need to be monitored.

Property, conferences and exhibitions, and Airport City-related businesses support HKIA’s long-term revenue diversification, but in the initial phase they also involve substantial investment and execution risk. FY2024/25 property income was HK$0.32bn and conferences and exhibitions income was HK$0.75bn, smaller than airfield income and retail income. AAHK is pursuing AsiaWorld-Expo Phase 2, Airport Bay Marina, art storage facilities, autonomous buses, SKYTOPIA, and other projects, aiming to expand the airport island from a mere transit point into a multi-use hub for consumption, exhibitions, logistics, and leisure. However, these are long-term assets and entail near-term risks related to capital expenditure, utilisation, tenant attraction, project management, and demand volatility.

Cargo and logistics-related income is not easily visible as a single revenue line in segment information, but it is important to the HKAA credit. Cargo connects airlines, cargo terminals, logistics operators, GBA manufacturing and consumption areas, e-commerce, cold-chain logistics, and high-value goods. Dongguan Logistics Park is a strategy to extend Hong Kong airport’s processing into pre-processing and transshipment on the Mainland side, and could become a means of expanding revenue without relying solely on physical capacity on the airport island. UPS’s new hub, the Air-Land Fresh Lane, the Cargo Data Platform, and Cargo Connect support service quality and stickiness as a cargo hub. However, cargo is sensitive to geopolitics, trade tensions, regional conflicts, inventory adjustment, and air freight rates, and monthly regional exports can decline sharply, as seen in March 2026.

The Airport Construction Fee (“ACF”) is different from both ordinary revenue and government subsidy. According to AAHK’s official explanation, ACF has been collected from air tickets issued from 1 August 2016 as part of the financial arrangements for 3RS, will continue until all 3RS-related borrowings are repaid, and the rates are fixed during the collection period. ACF is important as a repayment source for 3RS borrowings because cash collections increase as passenger demand recovers. However, ACF is a purpose-linked charge levied on passengers and does not have the same flexibility as ordinary commercial income. Higher passenger throughput is supportive, but investors should not assume tariff increases or unrestricted use of proceeds.

5. Financial Profile and Analysis

AAHK’s financial profile combines post-pandemic revenue recovery with high post-3RS leverage. From FY2020/21 to FY2022/23, the sharp decline in passenger traffic led to negative or low EBITDA and continuing losses attributable to the ordinary shareholder. In FY2023/24, revenue recovered to HK$13.68bn, EBITDA to HK$5.40bn, and profit attributable to the ordinary shareholder to HK$1.61bn. In FY2024/25, these improved further to revenue of HK$16.40bn, EBITDA of HK$7.37bn, and profit attributable to the ordinary shareholder of HK$2.46bn. Operationally, AAHK has clearly moved out of the extreme stress of the pandemic period.

However, financial improvement should not be assessed by earnings alone. AAHK materially increased borrowings while completing 3RS and related facilities. Total borrowings rose 45.2% from HK$111.67bn at FY2023/24 year-end to HK$162.16bn at FY2024/25 year-end, and total borrowings to capital increased from 56% to 64%. Because cash and bank balances were HK$54.52bn at FY2024/25 year-end, net borrowings to net capital remained at 54%, but this also reflects the timing of borrowings and treasury management. A simple calculation of net borrowings to EBITDA for FY2024/25 gives around 14.6x, indicating a heavy debt burden even for airport infrastructure. S&P’s adjusted metrics such as FFO/debt have not been directly confirmed in this report, but company disclosures alone show that debt capacity remains thin after the recovery in earnings.

1H FY2025/26 shows the tension between revenue and financial burden. Revenue increased from HK$7.80bn in the prior-year period to HK$8.84bn. “Operating profit before depreciation and amortisation,” which is close to EBITDA, was HK$3.65bn, slightly above HK$3.57bn in the prior-year period. However, depreciation and amortisation was HK$2.08bn, finance costs were HK$0.57bn, and interest income was HK$0.52bn, causing net finance income/expense to deteriorate from positive HK$0.32bn in the prior-year period to negative HK$0.05bn. As a result, profit for the period was HK$1.28bn, below the prior-year period. This shows that while demand is recovering, the post-3RS increase in assets and debt costs is absorbing earnings.

Cash flow should be read in the same way. In 1H FY2025/26, net cash generated from operating activities was HK$3.42bn, indicating that airport operations are generating cash. At the same time, investing activities included HK$8.57bn of payments for purchases of property, plant and equipment, land use rights, and related items. Financing activities included HK$18.24bn of repayments of notes, bonds, and bank borrowings, HK$1.3bn of dividends, and about HK$2.94bn of interest payments. Finance costs of HK$0.57bn in the income statement and interest paid in the cash flow statement should not be compared mechanically, as they may include differences in capitalised interest and presentation line items. Cash and cash equivalents at period-end were HK$4.79bn, while cash and bank balances on the balance sheet were HK$29.04bn. Because the scope of cash balances differs depending on deposit maturity, short-term liquidity should be assessed by considering cash and bank balances, maturity, and access to external borrowings together.

Asset quality in the banking sense is not the central credit risk for AAHK. The important question is whether capital invested in fixed assets and land use rights will be converted into future airport charges, commercial income, ACF, cargo and logistics income, and Airport City income. At end-September 2025, other property, plant and equipment was HK$198.69bn and land use rights were HK$21.89bn, accounting for the majority of total assets. These assets are illiquid and are not the type of assets that can be sold to repay debt. Repayment sources remain airport operating cash flow, ACF, market funding, and support expectations related to the government when needed.

Financial supports are revenue recovery, positive EBITDA, substantial cash and bank balances, market access, and government-related status. Constraints are the absolute amount of borrowings, high net borrowings to EBITDA, remaining capital expenditure, finance costs, variability in airport demand, and the ramp-up of new assets such as T2 and SKYTOPIA. The current financial profile is therefore one in which “repayment capacity is returning through operating recovery, but several years of strong cash flow are still needed to reduce post-3RS debt.”

6. Structural Considerations for Bondholders

From the perspective of bondholders, AAHK’s structure is relatively straightforward, but the interpretation of government support is not. The 2026 HKD notes are direct, unconditional, unsubordinated, and unsecured obligations of Airport Authority and rank at least pari passu with AAHK’s other unsecured obligations. At the issuer level, bondholders have claims on airport operating cash flow, ACF, cash, and capital markets access. They do not, however, have a direct claim on the Hong Kong Government. The bonds are neither secured project bonds nor government-guaranteed bonds.

This point is especially important in Hong Kong quasi-sovereign investment. Bonds issued by government-owned enterprises or statutory bodies often price in strong government support in the market. Legally, however, support expectations and guarantees are different. The disclosure incorporated in the 2026 Supplemental Offering Circular states that the Hong Kong Government does not guarantee AAHK’s debt and has no statutory or other obligation to provide direct or indirect financial support for AAHK’s outstanding debt. This does not negate the high rating; rather, it is the starting point for investors to understand their legal recovery rights correctly.

AAHK’s structural support lies in the fact that the airport itself is economic infrastructure for Hong Kong. It is reasonable to think that the government is unlikely to abandon AAHK. If airport operations stopped, passengers, cargo, tourism, connectivity as a financial city, and transport and logistics policy with the GBA would all be affected. AAHK is not merely an operator of commercial facilities; it is the vehicle through which the Hong Kong Government implements its policy objective of maintaining an international aviation hub. This policy importance contributes materially to low default risk and strong market access.

At the same time, government-related status is not a structure designed solely to maximise bondholder interests. The government has broad objectives covering airport charges, air traffic rights, GBA connectivity, tourism policy, Airport City, dividends, capital policy, public safety, security, and the environment. AAHK’s statutory mandate under the Ordinance includes prudent commercial principles, but it also has a role as public infrastructure. Therefore, a high likelihood of government support is not the same as saying that the fastest deleveraging path for creditors will always be prioritised.

The treatment of perpetual capital securities is also a point to monitor. Total capital at FY2024/25 year-end and at end-September 2025 included HK$11.585bn of perpetual capital securities. These are treated as equity for accounting purposes, but investors need to analyse distributions, redemption, subordination, step-up, and accounting and rating equity credit as hybrid instruments between ordinary shares and senior debt. In April 2026, a redemption notice was issued for US$750mn senior perpetual capital securities, and the capital, liquidity, and rating treatment should be confirmed in the next update.

The Airport Construction Fee is an institutionally important source of repayment for 3RS. Because ACF is collected until all 3RS-related borrowings are repaid, recovery in passenger traffic increases the repayment source. However, based on the information confirmed for this report, ACF is not treated here as collateral for bondholders or as a dedicated waterfall. Without confirming the collection period, unused balances, linkage with debt repayment, and sensitivity to passenger throughput, the speed of deleveraging can be misread.

7. Capital Structure, Liquidity and Funding

AAHK’s capital structure shifted materially toward debt as a result of 3RS. At FY2024/25 year-end, total borrowings were HK$162.16bn and total capital was HK$92.09bn, resulting in total borrowings to capital of 64%. The company-defined net borrowings to net capital ratio, after deducting cash and bank balances of HK$54.52bn, was 54%. At end-September 2025, total interest-bearing debt was HK$144.14bn and cash and bank balances were HK$29.04bn. On the surface, borrowings declined, but the actual treasury position moves significantly with the timing of large repayments, refinancing, investment spending, and cash holdings, especially given the HK$19bn notes issued in May 2026.

Liquidity should be assessed not only by cash but also by market access. Cash and bank balances of HK$29.04bn at end-September 2025 comfortably exceeded current interest-bearing debt of HK$8.85bn at the same date. However, cash and cash equivalents in the cash flow statement were HK$4.79bn, which differs from cash and bank balances including deposits with maturities exceeding three months. In addition, capital expenditure commitments at end-September 2025 were HK$15.88bn contracted and HK$28.71bn authorised but not contracted, for a total of HK$44.59bn. Short-term payment capacity has not become an issue, but funding needs over a multi-year horizon remain large.

In the maturity profile, at FY2024/25 year-end, the repayment amount within one year for interest-bearing debt based on contractual undiscounted cash flows was disclosed at HK$32.75bn. The company stated that it would address this short-term liquidity risk using internal resources and new external borrowings. In 1H FY2025/26, HK$18.24bn of borrowings was repaid, and the HK$19bn bond issue in April-May 2026 also provided funding for refinancing existing debt and capital expenditure. AAHK has a high rating and access to the Hong Kong dollar market, but debt repayment is not a structure naturally funded by operating cash flow alone; it combines operating cash flow with continued market access.

On currency, AAHK issues debt in multiple currencies including Hong Kong dollars, US dollars, and renminbi. Hong Kong dollar debt aligns more easily with Hong Kong dollar revenues. US dollar debt is relatively manageable from an FX risk perspective because of the Hong Kong dollar peg, but is affected by US dollar interest rates, hedging costs, long-term rates, and international investor appetite for Hong Kong risk. The interim financial statements at end-September 2025 disclose fixed-rate retail bonds, US dollar, renminbi, and Hong Kong dollar fixed-rate notes, cross-currency swaps, and interest rate swaps. These indicate risk management, but derivative valuation movements and hedging costs may affect comprehensive income and finance costs.

Funding access is very strong. The 2026 HK$19bn notes raised large-scale three-year, five-year, and ten-year Hong Kong dollar funding, supported by substantial investor demand. In 2025, AAHK also issued multiple tranches in US dollars, Hong Kong dollars, and renminbi, and the MTN Programme has been increased to U.S.$20bn. This shows that, as a Hong Kong quasi-sovereign, AAHK has broad access to domestic and international markets. However, the ability to raise funding is not the same as having a light debt burden. Investors in AAHK should understand that they hold a “highly rated, high-access, refinancing-based infrastructure issuer.”

The deleveraging path should be monitored in three parts. First, EBITDA and operating cash flow should increase through recovery in passenger throughput, aircraft movements, and commercial spending. Second, ACF should be used to repay 3RS-related borrowings, with collections increasing as passenger throughput recovers. Third, T2, Airport City, cargo and logistics, and GBA projects should generate additional revenue, while the capital expenditure peak should pass. If these factors align, AAHK can gradually reduce leverage while maintaining its high rating. Conversely, if demand recovery slows, additional investment increases, dividends or policy investments are prioritised, and market rates remain high, improvement in debt metrics will be delayed.

8. Rating Agency View

The central rating confirmed in AAHK’s public materials is S&P Global Ratings’ AA+. The Financial and Operational Highlights in the FY2024/25 annual report show both S&P’s long-term local-currency rating and long-term foreign-currency rating at AA+. The May 2026 HK$19bn notes are also described in the Supplemental Offering Circular and AAHK’s issuance press release as expected to receive an AA+ rating from S&P. This indicates very high support-inclusive credit strength as a Hong Kong government-related infrastructure issuer.

The sovereign and quasi-sovereign context of the Hong Kong Government is important in interpreting the rating. The Hong Kong Government’s own ratings, as confirmed in government releases as of May 2025, were S&P AA+ / Stable, Moody’s Aa3 / Stable, and Fitch AA- / Stable. In the HKSAR Government’s Green Bonds / Infrastructure Bonds issuance in May 2026, the government bonds were rated Fitch AA-, Moody’s Aa3, and S&P AA+. AAHK’s S&P AA+ is naturally read as incorporating the strong link with the Hong Kong Government and its policy importance.

At the same time, it would be inappropriate to explain AAHK’s rating solely by stand-alone financial strength. FY2024/25 EBITDA recovered to HK$7.37bn, but total borrowings were HK$162.16bn, and simple net borrowings to EBITDA was high. For a normal private-sector airport operator, this leverage alone would make it difficult to explain an AA+ rating. AAHK’s high rating should be understood as a support-inclusive assessment combining 100% Hong Kong Government ownership, the difficulty of substituting HKIA, Hong Kong’s international hub policy, capital markets access, and institutional repayment sources including ACF.

However, the latest full S&P issuer credit report, stand-alone credit profile, FFO/debt calculation, and rating triggers were not obtained for this report. Therefore, the rating interpretation here is based on AAHK’s and the Hong Kong Government’s public materials, issuance documents, and confirmed rating indications, not on S&P’s detailed model assumptions themselves.

A high rating is the starting point of investment analysis, not the endpoint. S&P’s AA+ indicates low default risk and strong refinancing capacity, but it does not automatically determine the spread, maturity, currency, guarantee, investor protections, liquidity, or benchmark status of individual bonds. In particular, because AAHK bonds are not guaranteed by the Hong Kong Government, the spread to sovereign bonds should reflect government support expectations, airport stand-alone financials, debt scale, issue size, liquidity, currency, and tenor. This report does not confirm live spreads and therefore does not make a valuation call on whether bonds are cheap or rich.

Rating downside pressure could arise through two channels. The first is deterioration in the Hong Kong Government’s rating or outlook. If AAHK is positioned close to the Hong Kong Government’s credit quality, a downgrade in the sovereign’s fiscal, external, or institutional assessment would likely flow through to AAHK’s rating. The second is deterioration in AAHK’s stand-alone financials. If demand recovery stalls, EBITDA does not grow, ACF collections fall short of expectations, additional investment and debt increase, and FFO/debt or interest coverage deteriorates, headroom would narrow even in a support-inclusive assessment. Maintaining the rating requires not only policy importance but also normalisation of the post-3RS capital structure.

9. Credit Positioning

Within Hong Kong credit, AAHK is best positioned as a government-related infrastructure issuer very close to the sovereign, but not the sovereign itself. Compared with Hong Kong Government bonds, the difference is that AAHK bonds are not legally direct government debt, but unguaranteed senior debt of the airport operator. Compared with Hong Kong infrastructure and utility issuers such as MTR Corporation, Hong Kong Electric Investments, and CLP-related issuers, AAHK has a stronger direct government ownership link and the international hub function of the airport. Its business risk and support expectations differ materially from private real estate companies and airlines.

Compared with MTR, AAHK is a non-listed, 100% government-owned airport operator, with heavier concentration in the airport and aviation cycle and a larger post-3RS debt burden. At the same time, its policy importance and directness of government ownership are strong. Compared with regulated utilities such as HK Electric or CLP-type issuers, AAHK has less automatic cost recovery through tariffs, and its revenue depends on passengers, cargo, and commercial spending. Compared with Asian airports such as Incheon and Changi, HKIA’s global cargo leadership, GBA hinterland, 3RS, and 100% Hong Kong Government ownership are strengths, but single-airport concentration, demand exposure to Hong Kong and Mainland China, regional competition, and high leverage need to be assessed separately.

Relative value against Hong Kong Government bonds cannot be determined without live spreads. In principle, AAHK bonds have higher risk than Hong Kong Government bonds and should command a spread premium at the same maturity. The size of the premium should be determined by the strength of government support expectations, the same S&P rating, lack of guarantee, issue size, liquidity, tenor, currency, capital structure, and T2/SKYTOPIA execution risk. AAHK should not be treated as equivalent to Hong Kong Government bonds solely because it is rated AA+, but demanding the same risk premium as a private airport company or airline with weaker policy importance would also be excessive.

10. Key Credit Strengths and Constraints

AAHK’s greatest credit strength is the near-irreplaceable nature of its monopoly operation of Hong Kong’s core international airport. HKIA is deeply embedded in Hong Kong’s passenger flows, cargo, finance, tourism, trade, and GBA connectivity. Handling 61.0 million passengers, 5.07 million tonnes of cargo, and 394,730 aircraft movements in 2025, and ranking as the world’s busiest cargo airport, show not merely scale but indispensability to the Hong Kong economy. This indispensability underpins government support expectations, market access, and investor demand.

The second strength is 100% Hong Kong Government ownership and the statutory policy link. AAHK is not a private airport company, but a statutory body corporate under Cap. 483, with all capital owned by the Hong Kong Government. The Hong Kong Government places policy importance on HKIA’s functions through air traffic rights, transport, GBA integration, tourism, logistics, and Airport City. Judging from ratings and issuance market response, investors significantly incorporate this government-related status.

The third strength is demand recovery and long-term capacity from 3RS. Post-pandemic revenue recovery is confirmed in the figures. EBITDA improved from HK$0.81bn in FY2022/23 to HK$7.37bn in FY2024/25, and profit attributable to the ordinary shareholder returned to positive territory. 3RS expands long-term capacity to 120 million passengers and 10 million tonnes of cargo. The physical capacity to capture future demand growth supports long-term credit quality.

The fourth strength is capital markets access. The 2026 HK$19bn notes attracted 2.9x demand despite market uncertainty. S&P AA+, the depth of the Hong Kong dollar market, issuance experience across multiple currencies including US dollars and renminbi, and the expansion of the MTN Programme show that AAHK is an issuer capable of executing refinancing.

The largest constraint, however, is the post-3RS debt burden. At FY2024/25 year-end, total borrowings were HK$162.16bn, total borrowings to capital was 64%, and net borrowings to net capital was 54%. EBITDA has recovered, but the absolute amount of debt is large and simple net borrowings to EBITDA is high. At end-September 2025, total interest-bearing debt was still HK$144.14bn, and capital expenditure commitments remained at HK$44.59bn. Without continued demand recovery, deleveraging will be delayed.

The second constraint is the absence of a government guarantee. Government ownership and policy importance are strong, but AAHK bonds are not guaranteed by the Hong Kong Government. Bondholders rely on AAHK’s credit quality and cannot make a direct claim against the government. In a stress scenario, some form of government support is likely in our view, but the form, speed, and conditions of support differ from a contractual guarantee. Investors should not infer legal protection solely from the high rating.

The third constraint is volatility in passenger and cargo demand. The history of passenger traffic almost disappearing during the pandemic and EBITDA turning negative shows that even airport infrastructure cannot fully avoid demand shocks. Geopolitics, epidemics, regional conflicts, aviation fuel prices, airline supply constraints, the Hong Kong and Mainland China economies, US-China trade tensions, FX, and consumer spending can all affect demand. Even with the world’s leading cargo position, regional exports can decline sharply, as seen in March 2026.

The fourth constraint is policy investment and capital policy. T2, Airport City, SKYTOPIA, Dongguan Logistics Park, GBA connectivity, art storage, marina facilities, autonomous transport, and other initiatives support long-term revenue diversification and policy objectives. In the short term, however, they entail capital expenditure, utilisation, tenant attraction, and execution risk. In addition, the resumption of dividends in FY2024/25 is a signal of financial recovery, but it also reminds investors that dividends to the government may be prioritised over debt reduction.

11. Downside Scenarios and Monitoring Triggers

The most realistic downside scenario is a combination of slower demand recovery and high leverage. If passenger and cargo traffic grow less than expected and the additional capacity from T2 and 3RS is not sufficiently monetised, EBITDA and operating cash flow growth will slow. At the same time, 3RS-related borrowings, T2, SKYTOPIA, logistics facilities, and refinancing of existing debt will continue. If operating cash flow does not sufficiently exceed capital expenditure and interest payments, borrowings will remain elevated and rating headroom will narrow.

The second downside scenario is an aviation and cargo demand shock. If epidemics, geopolitics, regional conflicts, airline supply constraints, higher fuel prices, a slowdown in Hong Kong and Mainland China, US-China trade tensions, and weak tourism spending overlap, passenger traffic, cargo, and commercial income could all slow at the same time. Retail, advertising, and terminal commercial income are influenced not only by passenger volumes but also by spending per passenger. Even with the world’s leading cargo position, short-term declines can occur in specific export regions.

The third downside scenario is deterioration in capital markets access. AAHK has a high rating and strong market access, but because its capital structure depends on refinancing, it is exposed to interest rates, Hong Kong dollar bond supply and demand, US dollar rates, the Hong Kong Government rating, and investor risk appetite toward China and Hong Kong. The 2026 HK$19bn issuance demonstrated strong market access, but future funding may not be available on the same terms. If long-term rates remain elevated, spreads widen, and maturities become concentrated, interest expense and refinancing costs will pressure credit quality.

The fourth downside scenario is a reassessment of government support expectations. A downgrade of the Hong Kong Government rating, weaker fiscal capacity, greater government demands for dividends or policy investment from AAHK, politicisation of airport charge policy, or ambiguity around the form of government support could weaken support-inclusive credit quality. AAHK is very close to the government, but it is not a government-guaranteed issuer, so changes in support expectations can have a direct effect on spreads.

The fifth downside scenario is project execution risk. T2 departure facilities are scheduled to open on 27 May 2026 and had not yet commenced operations as of this report date. If the transition is not smooth, airline relocation is delayed, passenger flows or security and immigration processing are disrupted, or commercial facilities do not ramp up as expected, there could be short-term effects on reputation, costs, and revenue. SKYTOPIA and Airport City are longer-term mixed-use developments, and demand, tenants, construction costs, and investment returns need to be monitored continuously.

The sixth downside scenario is risk in individual bond terms. Even when issuer credit is strong, the guarantee, ranking, security, covenants, tax, governing law, listing, liquidity, currency, and hedging of each bond affect investor risk. The 2026 HKD notes are confirmed as direct, unconditional, unsubordinated, unsecured, and pari passu, but not all outstanding bonds and perpetual securities have the same investment characteristics. In particular, perpetual capital securities, long-dated USD bonds, CNY bonds, and HKD retail bonds should be assessed separately by product features.

12. Credit View and Monitoring Focus

AAHK’s current credit quality sits in the high-rating category as a government-related airport infrastructure issuer very close to the Hong Kong Government, but legally it is not direct debt of the Hong Kong Government, and the issuer’s stand-alone debt burden is heavy. The credit direction is improving operationally due to passenger and cargo recovery, 3RS commissioning, T2 opening preparations, and the successful HK$19bn issue, but leverage normalisation is still at an early stage and the pace of improvement depends on multi-year demand recovery and the peaking-out of capital expenditure. The likelihood of rapid credit deterioration is not high under normal conditions, but if a deterioration in the Hong Kong Government rating, an aviation demand shock, worsening market funding conditions, and delays in T2/SKYTOPIA investment overlap, spreads and the stand-alone financial assessment could worsen relatively quickly.

This view is supported by HKIA’s near-irreplaceable role, 100% Hong Kong Government ownership, S&P AA+, and market access demonstrated by the 2026 HK$19bn issuance. At the same time, total borrowings of HK$162.16bn at FY2024/25 year-end, total interest-bearing debt of HK$144.14bn at end-September 2025, and capital expenditure commitments of HK$44.59bn show that AAHK, while a low-risk Hong Kong quasi-sovereign, is not a low-leverage issuer. Bond investors need to price both the very strong government support expectations and the fact that individual bonds are not government-guaranteed.

Monitoring should prioritise the FY2025/26 full-year annual report, the ramp-up of T2 after 27 May 2026, monthly passenger and cargo traffic, ACF collections, EBITDA, operating cash flow, capital expenditure, total borrowings, cash and bank balances, finance costs, dividends, the post-2026 issuance maturity profile, S&P rating commentary, and the HKSAR Government rating. In particular, even if passenger numbers increase after 3RS, credit improvement will not progress as quickly as the rating might suggest unless profit and operating cash flow sufficiently exceed finance costs, investment spending, and dividends.

Short Summary & Conclusion

Airport Authority Hong Kong is a government-related airport infrastructure issuer, 100% owned by the Hong Kong Government, that operates and develops HKIA. Passenger and cargo recovery, one of the world’s largest cargo hub positions, long-term capacity from 3RS, S&P AA+, and strong market access support the credit, while total borrowings of HK$162bn at FY2024/25 year-end, the absence of a government guarantee, and continuing investment such as T2 and SKYTOPIA constrain the assessment. HKAA bonds are viewed as quasi-sovereign debt very close to the Hong Kong Government, but they are not direct government obligations, and investors should separately monitor deleveraging, ACF, monthly traffic, individual bond terms, and the Hong Kong Government rating.
