1. Business Snapshot and Recent Developments

BOC Aviation Limited (“BOC Aviation”) is a major aircraft leasing company headquartered in Singapore and listed on the Hong Kong Stock Exchange. For credit analysis purposes, it should be viewed not as an airline, but as a non-bank aviation finance issuer that owns and orders aircraft, leases them to airlines under long-term leases, and funds those aircraft assets and lease receivables through US dollar bank borrowings and capital market funding. Air passenger demand, fuel prices and airline earnings conditions affect BOC Aviation not directly, but through lease payments, aircraft remarketing, asset values and lease renewal terms. Misreading this indirect transmission channel risks confusing airline operating risk with the asset and funding risks of an aircraft lessor.

The company is part of the Bank of China group, and Bank of China Limited is its ultimate controlling shareholder. This is an important support for capital market access, banking relationships, liquidity back-up and rating agency support assessments. However, BOC Aviation’s bonds should not be treated as obligations explicitly guaranteed by Bank of China or the Chinese government. The specific forms of support that can be verified from company materials centre on committed unsecured revolving credit facilities from the Bank of China group, intra-group relationships, and access to bank and capital markets; these are distinct from a legal guarantee that unconditionally covers principal and interest payments on individual bonds. In this report, the country bucket is kept as Singapore, in line with the user’s designation, while the relationship with the BOC group, capital market access and the link to a Chinese state-owned banking group are treated separately as structural considerations.

As of end-December 2025, BOC Aviation had 462 owned aircraft and engines, 16 managed aircraft, an orderbook of 337 aircraft and engines, and a total portfolio of 815 aircraft and engines. It served 87 airline customers across 46 countries and regions. Owned aircraft utilisation was 100%, the average aircraft age was 5.0 years, and the average remaining lease term was 7.8 years. This indicates not merely a large aircraft count, but an issuer with a young fleet, long remaining lease terms and a broad customer base. The quality of lease income is determined by the combination of airline customer payment capacity, lease maturity diversification, the remarketing flexibility of aircraft types, aircraft values and funding costs.

On a reported basis, full-year 2025 earnings declined from the prior year, but from a credit perspective the year should be read as one in which underlying earnings power improved. On 19 March 2026, the company announced 2025 revenues and other income of US$2.619bn, reported net profit after tax of US$787mn and underlying net profit after tax of US$746mn. Reported NPAT in 2024 was US$924mn, so headline earnings declined. However, 2024 was materially affected by Russia-related insurance recoveries and impairment reversals, while the company’s underlying NPAT rose by 18%, from US$633mn in 2024 to US$746mn in 2025. Investors therefore need to distinguish between the underlying earnings of the aircraft leasing business and one-off recoveries, rather than relying only on the year-on-year movement in reported NPAT.

Cash flow is also important. Operating cash flow net of interest was US$2.2bn in 2025, which the company described as a record high. For an aircraft lessor, the key question is less accounting profit in isolation and more how much operating cash remains after interest payments from long-term leases to support orderbook-related capital expenditure, refinancing, dividends and aircraft trading. At end-2025, total assets were US$26.3bn, aircraft assets were US$22.8bn and total equity was US$6.8bn. The debt burden is substantial, with both gross debt to equity and net debt to equity at 2.5x. BOC Aviation’s credit profile should therefore be understood not as “high profitability with low leverage”, but as a structure in which high-quality aircraft assets and long-term leases are supported by high but managed leverage and substantial liquidity.

Funding depth was confirmed in early 2026. On 16 February 2026, the company renewed its US$3.5bn unsecured committed revolving credit facility with the Bank of China group and extended the maturity to February 2031. On 12 March 2026, it signed a US$2.0bn self-arranged club loan. This comprised a US$1.0bn five-year unsecured term loan, a US$0.5bn five-year unsecured committed revolving credit facility and a US$0.5bn seven-year unsecured term loan. In 1Q 2026, the company also issued a US$500mn seven-year 4.375% bond, bringing total debt financing raised during the quarter to US$2.5bn. For an aircraft lessor, funding capacity to support long-term aircraft orders and long-term leases is central to credit quality, and the early-2026 funding activity reinforces this point.

However, strong early-2026 funding does not mean that the issuer should be viewed as low-risk. Committed capital expenditure was US$19.1bn at end-2025, comprising US$3.2bn in 2026, US$2.1bn in 2027, US$2.4bn in 2028 and US$11.4bn thereafter. The orderbook is large at 337 aircraft, and OEM delivery delays, price escalation, PDPs, lease commitments to customers and changes in funding markets will all shape future funding needs and asset growth. The strength of an aircraft lessor lies not in simply owning aircraft, but in placing the right aircraft with the right customers on the right lease terms and yields, while securing funding in advance.

The latest credit snapshot is as follows.

2. Industry Position and Franchise Strength

Aircraft leasing is a capital-intensive finance business at the intersection of airline capital constraints, fleet renewal demand, OEM supply constraints, interest rates and aircraft residual values. BOC Aviation’s strengths lie in the combination of global scale, a young fleet, long remaining lease terms, airline and geographic diversification, and its relationship with the Bank of China group. Its average aircraft age of 5.0 years and average remaining lease term of 7.8 years at end-2025 help mitigate residual value risk on older aircraft and near-term re-lease risk. However, young aircraft also have high acquisition costs, so the balance among lease rentals, funding costs and residual values needs to be monitored continuously.

The company’s fleet mix is heavily weighted towards narrowbody aircraft, which supports remarketing flexibility. The aircraft counts in the table below represent the end-2025 composition of the total 815 owned aircraft, managed aircraft, aircraft on order and engines. They therefore include not only existing assets but also future deliveries. The interpretation of existing asset values and the interpretation of future deliveries and funding needs must be kept separate.

Customer and geographic diversification are also supportive. At end-2025, the company had 87 customers across 46 countries and regions. By net book value, the regional split was Americas 40.0%, Asia Pacific excluding Chinese mainland / Hong Kong / Macau / Taiwan 19.6%, Chinese mainland / Hong Kong / Macau / Taiwan 16.1%, Europe 14.5%, and Middle East and Africa 9.8%. However, by 2025 revenue, the largest customer accounted for 11% and the top five customers accounted for 34%. If top-customer credit quality, regional aviation demand, currencies, regulation and sanctions were to deteriorate at the same time, lease payments and remarketing could be affected.

The 337-aircraft orderbook is a franchise strength in the sense that it secures aircraft that airlines will need in the future, but it is also a source of funding need and execution risk. In 2025, the largest supplier was Boeing, which accounted for 54% of capital expenditure, while the top five suppliers accounted for 99%. Delivery delays and engine supply constraints can support the value of existing aircraft, but they also create uncertainty for BOC Aviation’s own growth plan, PDPs, capital expenditure and interest burden.

BOC Aviation is a major aircraft lessor with the distinctive feature of a strong link to the Bank of China group. This supports funding, but it is not the same as parent-guaranteed bonds. Young aircraft assets, customer diversification, OEM ordering capacity and the relationship with the BOC group are strengths. At the same time, the asset cycle, airline credit, funding markets and the legal limits of support expectations need to be analysed separately.

3. Aircraft Portfolio, Lease Cash Flow and Residual Value Risk

The core of BOC Aviation’s credit quality is the quality of its aircraft portfolio and the stability of lease cash flow. The repayment source is lease rentals from airlines, while the collateral-like support is the residual value of the aircraft themselves. The 100% utilisation rate at end-2025 is a strong metric, but it is a point-in-time figure and could change in the event of airline bankruptcies, sanctions, grounding of specific aircraft types or demand shocks.

An average remaining lease term of 7.8 years and the structure under which 72.0% of the operating lease portfolio by net book value has lease expiry in 2032 or later increase revenue visibility. On the other hand, long lease terms can also mean that existing lease yields do not immediately rise in periods of higher interest rates or higher aircraft values. At end-2025, fixed rate leases were 89%, while fixed rate funding including interest rate swaps was 72%, which suggests that near-term interest rate mismatch is mitigated to a degree, but not fully hedged.

On aircraft asset values, the company states that the appraised value of its operating lease fleet at end-2025 exceeded net book value by US$3.4bn, or 18%. This supports aircraft sales, collateral value and leverage assessment, but appraisal values can narrow under stress. The 2025 net gain on sale of aircraft of US$213mn is also evidence of portfolio management capability, but it is not of the same quality as recurring lease income.

Russia-related insurance recoveries and remaining risk also need to be incorporated into this asset value assessment. BOC Aviation experienced related impairments and insurance recoveries in prior years, and the gap between 2025 reported NPAT and underlying NPAT shows the need to separate one-off items. War risk, insurance recoveries, sanctions, aircraft location and legal claims remain important tail risks for aircraft lessors, even if they occur infrequently.

BOC Aviation’s portfolio therefore has clear strengths: a young narrowbody-heavy fleet, 100% utilisation and long lease terms. However, aircraft are not liquid assets. Under stress, remarketing, maintenance, regulation, insurance and airline negotiations can take time. Actual repayment capacity depends on airline payments and capital market refinancing.

4. Segment Assessment and Earnings Drivers

BOC Aviation’s sources of earnings can broadly be divided into operating leases, finance leases, aircraft sales and portfolio management, and other fee and interest income. The segment interpretation differs from product-by-product profit analysis for an industrial company; the key is to distinguish which earnings are recurring and which are closer to asset sales or one-off items. Revenues and other income were US$2.619bn in 2025, with lease rental income of US$1.890bn forming the core. This is long-term contractual income and is the foundation of BOC Aviation’s credit quality.

Operating lease income is the highest-quality revenue source from a credit perspective. As long as airlines pay according to contract, aircraft remain in service and lease terms remain outstanding, revenue is relatively predictable. However, operating lease income depends on airline credit. BOC Aviation does not buy fuel itself, but if fuel prices, exchange rates, airport constraints, labour negotiations or geopolitics pressure airlines, lease payments and renewal terms can be affected.

Finance lease income is closer in accounting substance to lending. Interest income from finance leases was US$271mn in 2025. It provides cash flow visibility during the contractual period, but counterparty credit, contractual terms, aircraft residual values and legal protection by jurisdiction are important. Aircraft gains on sale show portfolio management capability, but the 2025 net gain on sale of aircraft of US$213mn should not be treated as having the same stability as lease income.

PDP financing and orderbook-related income are also aircraft lessor-specific considerations. The larger the orderbook, the more important it becomes to manage purchase commitments, PDPs, lease commitments, payments to aircraft manufacturers and funding timing. The full picture of PDP funding liquidity is not sufficiently verifiable from public company materials, so delivery delays should not be treated as simply positive or negative; they should be viewed as timing differences between cash flow and lease contracts.

Overall, BOC Aviation’s earnings have stability centred on lease income, but total profit is affected by gains on sale, insurance recoveries, interest rates, asset values, and the delivery and ordering cycle. The increase in 2025 underlying NPAT is credit-positive, but persistent earnings power should not be assessed solely by reported NPAT or aircraft gains on sale. The key question is whether long-term lease rentals from airlines generate sufficient operating cash after interest payments to support the large orderbook and debt burden.

5. Financial Profile and Analysis

BOC Aviation’s financial profile needs to be assessed by combining earnings, cash flow, asset scale, leverage and funding costs. For an aircraft lessor, asset growth tends to increase revenue, but also tends to increase debt. Therefore, credit quality cannot be judged from revenue or profit growth alone. The focus is whether lease income absorbs interest expense, operating cash flow supports capital expenditure and refinancing, and aircraft asset values provide sufficient headroom relative to leverage.

From 2023 to 2025, revenue increased gradually. Revenues and other income were US$2.461bn in 2023, US$2.557bn in 2024 and US$2.619bn in 2025. Reported NPAT was volatile at US$764mn in 2023, US$924mn in 2024 and US$787mn in 2025, but underlying NPAT increased from US$547mn in 2023 to US$633mn in 2024 and US$746mn in 2025. This shows that underlying earnings, excluding Russia-related recoveries, have recovered and improved. For an aircraft lessor, the earnings trend excluding such one-off items is important.

The notable point in the 2025 earnings improvement is operating cash flow after absorbing finance costs. Finance expenses were US$738mn in 2025, up from US$710mn in 2024. The average cost of funds was 4.5%, which is high compared with the previous low-rate environment. Even so, operating cash flow net of interest increased to US$2.175bn. This indicates that long-term lease income is absorbing higher interest rates to a degree. However, if interest rates remain higher for longer and existing fixed leases do not reprice quickly, margins will come under pressure. The gap between fixed rate leases at 89% and fixed rate funding at 72% leaves some mismatch.

On the asset side, aircraft assets of US$22.8bn account for the majority of total assets of US$26.3bn. Aircraft assets generate earnings, but their liquidity differs from bank deposits or government bonds. Aircraft can be sold, but saleability depends on price, buyer availability, whether the aircraft is on lease or off-lease, maintenance condition, aircraft type, region, registration, jurisdiction, sanctions and insurance. Therefore, what matters is not simply the size of total assets, but whether the aircraft are young, utilised, covered by long leases and in demand in the secondary market. The end-2025 appraised value premium is supportive, but should be viewed conservatively as stress-period liquidation value.

Leverage is one of the most important constraints in assessing BOC Aviation’s credit. Total indebtedness / gross debt used in this report is company-defined interest-bearing debt, centred on loans and borrowings, and stood at US$17.228bn at end-2025. Accounting total liabilities, calculated as total assets of US$26.3bn less total equity of US$6.8bn, are approximately US$19.5bn, which is a broader liability concept than the interest-bearing debt above. Gross debt to equity of 2.5x is not excessively unusual for an aircraft lessor, but it is high compared with an ordinary industrial company. If financial market access were disrupted, asset growth and refinancing would be affected. Aircraft lessors operate by matching long-term leases with long-term funding, so maintaining investment-grade ratings and banking relationships has significance close to credit quality itself.

On profitability, ROE was 11.9% in 2025, which is an adequate profit level for a leasing company. However, high ROE should not be read as simple credit improvement. ROE can be inflated by leverage and can also be affected by aircraft gains on sale and one-off income. For bond investors, operating cash flow, interest coverage, liquidity, refinancing capacity, asset values and orderbook funding needs are more important than ROE.

The 2025 financial profile supports the foundation of an investment-grade issuer. Underlying profit increased, operating cash flow was strong, total equity increased and leverage was managed at 2.5x. However, this financial profile depends on aircraft asset prices and capital market access. If a sharp decline in aviation demand, airline bankruptcies, higher interest rates, lower aircraft values and closed funding markets occur at the same time, the high leverage would quickly become more visible. BOC Aviation’s financial profile is currently supportive, but stress resilience needs to be tested including liquidity and the orderbook.

6. Structural Considerations for Bondholders

There are three structural considerations for bondholders in BOC Aviation. First, the issuer is a consolidated company that owns and leases aircraft, and the repayment source for individual bonds is the group’s aircraft assets and lease income. Second, the relationship with the Bank of China group is important as credit support, but should not be confused with an explicit guarantee. Third, aircraft assets involve practical recovery elements such as security interests, lease contracts, jurisdictions, registration, insurance and repossession in the event of airline insolvency.

BOC Aviation is part of the Bank of China group, and this relationship clearly supports the issuer’s credit quality. At end-2025, the company had a US$3.5bn unsecured committed revolving credit facility from the Bank of China group, of which US$0.5bn was drawn and US$3.0bn was undrawn. In February 2026, the maturity of this facility was extended to February 2031. For an aircraft lessor, the quality and maturity of bank lines affect survivability under stress, making this long-term commitment credit-relevant.

However, this RCF is not a legal guarantee of the bonds. Even when BOC Aviation bond investors incorporate the relationship with the Bank of China group into their assessment, they still need to review the offering circular, pricing supplement, guarantees, negative pledge, change of control, cross default, pari passu provisions, governing law and issuing entity for individual bonds. Having a large parent and bank lines is not the same as the parent being certain to pay principal and interest if the issuer cannot. In particular, under market stress, investors should distinguish between the degree of support uplift incorporated by rating agencies and how far the issuer can withstand stress using only its stand-alone aircraft assets and liquidity.

The collateral-like nature of aircraft assets is also not straightforward. Looking at the end-2025 debt mix, secured term loans were small at US$53mn, with unsecured term loans, revolving credit facilities and medium-term notes accounting for most debt. This suggests that many assets may not be encumbered by security interests and that there may be asset headroom for unsecured creditors. On the other hand, unsecured creditors do not have direct security over individual aircraft; they are general creditors of the issuer and, in insolvency, are subject to jurisdictions, subsidiary structure, lease contracts, aircraft registration and local procedures. Details of unencumbered aircraft, the secured debt ratio and asset location by legal entity should be checked before investing in individual bonds.

In aircraft leasing, contractual rights and practical recovery are different. If an airline stops paying, the lessor may have the ability to repossess the aircraft, but in practice this depends on the country where the aircraft is located, airports, authorities, maintenance condition, aircraft registration, engine location, part-outs, insurance, sanctions and court procedures. The Russia-related experience showed that this risk is not merely theoretical. BOC Aviation has received insurance recoveries, but war risk, sanctions, insurance claims and the inability to repossess aircraft remain structural risks in aircraft leasing.

Another structural issue is dividends and growth investment. BOC Aviation is a listed company and returns capital to shareholders. The company states that it raised its dividend payout ratio from around 35% to around 50% in 2025. When earnings are strong and liquidity is ample, dividends are less likely to be problematic. However, for an aircraft lessor, orderbook capital expenditure, refinancing, airline payment delays and asset value declines can occur at the same time. Bond investors need to monitor continuously whether shareholder returns remain consistent with a financial policy that prioritises liquidity and leverage management.

Overall, BOC Aviation’s structure combines the BOC group relationship, unsecured funding, aircraft assets and capital policy as a listed company. Issuer credit is supported by the relationship with the Bank of China group, but individual bond investments require separate confirmation of legal guarantees, security, covenants, issuing entity and unsecured creditor access to assets. This report focuses on issuer credit, leaving individual bond terms as an unresolved item.

7. Capital Structure, Liquidity and Funding

BOC Aviation’s capital structure and liquidity are central to its credit quality. At end-2025, the company had total liquidity of US$6.9bn, comprising cash and short-term deposits of US$0.4bn and undrawn committed credit facilities of US$6.5bn. Cash itself is small relative to total assets and interest-bearing debt, but undrawn committed facilities are substantial. For an aircraft lessor, looking only at cash balances can understate liquidity, while looking only at undrawn facilities can understate reliance on the banking market and the BOC group relationship. Both need to be assessed together.

The Banker's Lunch 2026 presentation shows available liquidity of US$8.0bn as of 6 April 2026. This appears to reflect the early-2026 club loan and bond issuance. In 1Q 2026, the company raised US$2.5bn of debt financing, of which US$500mn was a seven-year 4.375% bond and US$2.0bn was loan facilities. In May 2026, the company also made announcements related to CNY-denominated 2029 bonds, indicating continued diversification by currency and investor base. However, this report has not confirmed the detailed terms of the CNY bonds.

The debt structure shows total indebtedness / gross debt of US$17.228bn at end-2025, comprising US$53mn of secured term loans, US$8.005bn of unsecured term loans, US$1.070bn of revolving credit facilities and US$8.100bn of medium-term notes. The structure is broadly balanced between bank loans and capital market bonds, so there is no single-market dependence. The small amount of secured term loans indicates that unsecured funding is the main form of funding and that aircraft assets may have room not tied up as collateral. Conversely, a large unsecured funding base also means that credit depends heavily on ratings, investor demand, banking relationships and the BOC group relationship.

The debt repayment profile at end-2025 was US$1.9bn in 2026, US$2.7bn in 2027, US$3.5bn in 2028 and US$9.1bn in 2029 and thereafter. There is no excessive near-term maturity wall, but there is recurring refinancing need each year in 2026–2028. Committed capital expenditure overlays this maturity profile, so the company needs funding not only to refinance existing debt, but also to acquire new aircraft. End-2025 committed capital expenditure comprised US$3.2bn in 2026, US$2.1bn in 2027, US$2.4bn in 2028 and US$11.4bn thereafter. Therefore, liquidity from end-2025 to early 2026 provides headroom against 2026 funding needs, but it is not permanent self-contained funding for refinancing and deliveries in 2027–2028 and beyond. Current liquidity should be viewed as a “time-buying buffer” to maintain continuous market access.

Putting maturities and the orderbook together shows that BOC Aviation is an issuer that always needs market access. End-2025 liquidity of US$6.9bn provides a degree of headroom even when 2026 debt maturities and capex are considered together, but capital expenditure will continue beyond 2027. For aircraft lessors, a rating downgrade or market closure would affect not only refinancing but also growth plans, deliveries and lease commitments to airlines. Maintaining the A- rating and Bank of China group facility is therefore not merely a credit enhancement but part of business continuity.

On interest rate risk, the balance between fixed rate leases and fixed rate funding is important. At end-2025, fixed rate leases were 89% and fixed rate funding including swaps was 72%. This indicates high fixed-rate characteristics on the lease income side and a substantial degree of fixed funding. However, the fact that the fixed lease ratio is higher than the fixed funding ratio means that floating rate funding or higher refinancing costs could affect margins. If interest rates decline, funding costs may improve, but in the short term the timing of interest rate movements matters because existing fixed leases reprice slowly.

The conclusion on liquidity is that BOC Aviation showed sufficient funding access for an investment-grade lessor from end-2025 into early 2026. Funding sources are broad, including the Bank of China group facility, 54 lenders, the MTN market, club loans and CNY bonds. However, cash balances are small, the orderbook is large and refinancing needs are recurring. The company’s liquidity is therefore strong, but its strength assumes continued access to capital and bank markets.

8. Rating Agency View

According to company materials, BOC Aviation is rated A- by S&P Global Ratings and Fitch Ratings. For an aircraft lessor, being positioned in the A category is important for capital market access and borrowing costs. For aircraft lessors, ratings are not merely labels; they broadly affect bank lines, MTN issuance, airline confidence, relationships with aircraft manufacturers, hedging transactions and the investor base. Maintaining the rating is therefore both an outcome of credit quality and a condition that supports credit quality.

The supports that rating agencies are likely to recognise include the young aircraft portfolio, long remaining lease terms, diversified customer base, 100% utilisation, stable operating cash flow, relationship with the Bank of China group and ample committed liquidity. The end-2025 average aircraft age of 5.0 years, average remaining lease term of 7.8 years, total liquidity of US$6.9bn, gross debt to equity of 2.5x and 2025 underlying NPAT of US$746mn appear consistent with the A- rating that can be verified from company materials. However, this report has not confirmed the split between stand-alone credit strength and support uplift from the BOC group relationship.

Rating constraints include the capital intensity of aircraft leasing, high leverage, indirect exposure to airline credit, the aircraft value cycle, continued dependence on external funding and orderbook-related funding needs. Aircraft lessors do not have a bank-like deposit base or utility-like regulated revenue. Therefore, even at the same A- rating level, the nature of credit risk differs from that of megabanks or utilities. BOC Aviation’s A- is that of an aviation finance issuer with asset quality and support, while sensitivity to the aviation cycle remains.

This report has not confirmed the full text of the latest detailed S&P and Fitch reports, the precise number of support notches, or the full downgrade and upgrade triggers. Therefore, it does not replace the rating agencies’ detailed views with this report’s analysis. At this stage, the A- rating that can be verified from company materials is used only as evidence of capital market access. In the next update, the latest rating action texts should be reviewed to confirm the incorporation of Bank of China support, stand-alone credit strength, leverage thresholds, liquidity assessment, aircraft value stress and the treatment of Russia-related items.

For bond investors, it is important to distinguish between the rating level and the protection level of individual bonds. Even if the issuer is rated A-, the security credit profile depends on whether the individual bond is unsecured or guaranteed, which issuing entity is used, whether there is a negative pledge, whether there is a change of control clause, how cross default is defined and other terms. In BOC Aviation’s case, parent support expectations are also separate from individual bond terms. Therefore, this issuer report treats the A- rating as a support for credit quality, but the offering circular and pricing supplement need to be reviewed before investing in individual bonds.

9. Credit Positioning

BOC Aviation is positioned as a high-quality investment-grade issuer within the aircraft leasing industry. Its young fleet, long remaining lease terms, 100% utilisation, A- rating and relationship with the Bank of China group are supportive within the peer group. However, this report has not verified live market data on spreads, bond liquidity, collateral structures, parent relationships or aircraft portfolio differences versus AerCap, Air Lease, Avolon, SMBC Aviation Capital, Aircastle and others, and therefore does not make definitive relative value conclusions.

Fundamentally, the practical approach is to treat BOC Aviation not as a “stable credit close to an A- bank”, but as a market-funded aviation finance credit with a BOC group relationship and young aircraft assets. The young narrowbody-focused portfolio supports asset liquidity, but the large orderbook leaves execution risk in relation to PDPs, delivery delays, manufacturer concentration and future lease placement. Buy, hold, sell and relative cheapness or richness should be judged only after reviewing actual spreads, tenor, individual bond terms and liquidity.

10. Key Credit Strengths and Constraints

BOC Aviation’s first strength is its young, utilised aircraft portfolio. The average aircraft age of 5.0 years, average remaining lease term of 7.8 years and owned aircraft utilisation of 100% at end-2025 support lease income visibility and asset value. The narrowbody-focused fleet mix is a strength from the perspective of airlines’ underlying demand and remarketing flexibility. For an aircraft lessor, asset quality leads to funding quality, so this portfolio quality is the starting point for credit strength.

The second strength is customer and geographic diversification. Diversification across 87 airlines and 46 countries and regions provides protection against stress at a single airline or in a single country. Regional NBV is also split among the Americas, Asia Pacific, Chinese mainland / Hong Kong / Macau / Taiwan, Europe, and Middle East and Africa. Top-customer concentration remains, but the largest customer at 11% and the top five customers at 34% indicate that the credit structure is not one in which stress at a single airline would immediately undermine issuer credit. However, the credit quality, region, currency and contractual terms of top customers have not been reviewed individually in this report, and the quality of diversification should be checked in the next update.

The third strength is the relationship with the Bank of China group and liquidity. Liquidity of US$6.9bn at end-2025, available liquidity of US$8.0bn as of April 2026, the US$3.5bn Bank of China group RCF and 54 lenders are lines of defence against the orderbook, refinancing and airline stress. In particular, the extension of the BOC RCF to 2031 is evidence not only of short-term liquidity, but also of confirmed BOC group liquidity back-up and continued relationship support.

The fourth strength is capital market access. The company raised US$4.3bn of debt financing in 2025 and US$2.5bn in 1Q 2026, demonstrating access to both bank and bond markets.

The first constraint is high leverage and the orderbook. Gross debt to equity of 2.5x, net debt to equity of 2.5x and interest-bearing debt of US$17.2bn may be manageable for an aircraft lessor, but under stress they become a large fixed burden. In addition, committed capital expenditure of US$19.1bn means that funding needs will continue. This is less likely to be an issue when aviation demand is strong and capital markets are open, but it becomes a constraint if airline stress and market closure occur at the same time.

The second constraint is airline credit and aircraft values. Even if lease contracts are long and aircraft are young, cash flow is disrupted if airlines cannot pay. Aircraft can be remarketed, but remarketing takes time and money, and sale prices fall in weak markets.

The third constraint is interest rates and funding costs. The average cost of funds was 4.5% in 2025 and finance expenses were US$738mn. Fixed rate funding of 72% mitigates a sharp short-term impact, but new interest rate conditions feed through at refinancing. Fixed lease and fixed funding mismatch, the long-term orderbook, bond maturities and repricing of bank lines need to be considered together.

The fourth constraint is the legal limit of the BOC group relationship. The relationship with the Bank of China group is a strong support, but issuer debt is not necessarily explicitly guaranteed. If the market questions support expectations, or if market views on Chinese state-owned banks and China-related credit change, BOC Aviation’s own assets, liquidity and rating will be tested. Support expectations are positive, but investors should not confuse them with legal protection.

11. Downside Scenarios and Monitoring Triggers

The most realistic downside scenario is one in which airline credit deterioration, lower aircraft values and a weaker capital market environment occur together. If recession, high fuel prices, geopolitics, currency depreciation and lower fares pressure airlines, payment delays, lease renegotiations, returns and airline bankruptcies may increase. BOC Aviation can remarket aircraft, but if multiple airlines weaken at the same time, re-lease terms, idle periods and maintenance and transfer costs would deteriorate. If this is accompanied by wider spreads or higher pricing on bank facilities, lease income, aircraft values and funding costs would deteriorate simultaneously.

The second downside is the funding burden from the orderbook and capital expenditure. BOC Aviation has a 337-aircraft orderbook and committed capital expenditure of US$19.1bn. Delivery delays, customer cancellations, lease commencement delays and weaker funding markets can create timing mismatches among PDPs, capital expenditure, idle assets and refinancing. Debt repayments of US$1.9bn in 2026, US$2.7bn in 2027 and US$3.5bn in 2028 overlap with capital expenditure, so maintaining market access over multiple years is important.

The third downside is a change in market perception of the BOC group relationship or insurance and war risk. The relationship with the Bank of China group is supportive, but the more support expectations are priced into the market, the greater the impact if those expectations weaken. In addition, as the Russia-related experience showed, war, sanctions, aircraft seizure, disputes with insurers, and aircraft registration and jurisdictional issues remain low-frequency but high-severity risks.

The monitoring items are as follows.

Before investing in individual bonds, it is necessary to confirm the issuing entity, guarantees, negative pledge, change of control, cross default, pari passu provisions, security, governing law, redemption provisions, descriptions of the BOC group relationship, and terms of each currency bond including CNY bonds. This report is an initial issuer credit review and does not analyse individual bond terms or make an investment recommendation based on market prices.

12. Credit View and Monitoring Focus

BOC Aviation’s current credit quality appears consistent with the A- rating verifiable from company materials and with an investment-grade aircraft leasing issuer profile. The young aircraft portfolio, 100% utilisation, average remaining lease term of 7.8 years, US$2.2bn of operating cash flow net of interest, liquidity in the US$6.9bn to US$8.0bn range and the relationship with the Bank of China group support ordinary-course repayment and refinancing capacity. However, this report has not confirmed how much of the A- rating reflects stand-alone credit strength and how much reflects support uplift from the BOC group relationship. The credit direction is biased towards stability, given the increase in 2025 underlying NPAT and early-2026 funding track record, but the large orderbook and high leverage mean that it is not yet appropriate to strongly anticipate an improving trajectory.

The main supports for credit quality are asset quality and liquidity. A young fleet with an average age of 5.0 years, a narrowbody-focused mix, long remaining lease terms and customer and geographic diversification strengthen the earnings base of the aircraft leasing business. The Bank of China group US$3.5bn RCF, the early-2026 US$2.0bn club loan and the US$500mn bond issue show that the company has funding access to address large capital expenditure and maturities. However, these are evidence of confirmed liquidity support and market access, not legal guarantees of individual bonds. They clearly distinguish the company from lower-rated airline credit.

The constraints are leverage, the orderbook, aircraft values and the legal limits of the BOC group relationship. Gross debt to equity of 2.5x may be acceptable for an aircraft lessor, but debt size becomes visible under stress. Committed capital expenditure of US$19.1bn is both a source of growth and future funding need. Aircraft assets have appraised values above book, but there is no guarantee that they can be sold at the same prices under stress. The relationship with the Bank of China group is significant, but separate from an unconditional guarantee of individual bonds.

The practical investor view is to treat BOC Aviation as an investment-grade aircraft leasing credit with a BOC group relationship and strong liquidity. However, it is not a stable credit in the same sense as a bank or utility. It is an asset finance credit sensitive to the aviation cycle, airline credit, aircraft residual values and dollar funding markets. Confirmed RCFs and liquidity reduce near-term concerns, but the capital intensity of aircraft leasing sets a ceiling on the credit assessment. Buy, hold or sell decisions require market spreads, tenor, individual bond terms and peer comparison; this report does not make that judgement.

The credit view would improve if orderbook deliveries and lease commencements progress as planned, utilisation and lease yields are maintained, gross debt to equity is managed around or below 2.5x, increases in the average cost of funds are absorbed by lease income, and the Bank of China group facility and capital market access continue. Conversely, the current stable view would need to be revisited if airline payment delays, lower aircraft values, lower gains on sale, impairments, higher orderbook funding needs, a negative rating outlook, reductions in RCFs or bank lines, and weaker BOC group support expectations occur together.

13. Short Summary & Conclusion

BOC Aviation is a major aircraft lessor headquartered in Singapore. At end-2025, it had 462 owned aircraft and engines, an orderbook of 337 aircraft, diversification across 87 airlines and 46 countries and regions, an average aircraft age of 5.0 years and an average remaining lease term of 7.8 years. Its young fleet, 100% utilisation, US$2.2bn of operating cash flow net of interest and the Bank of China group US$3.5bn RCF support credit quality, while gross debt to equity of 2.5x, US$19.1bn of orderbook-related capital expenditure, airline credit, aircraft values and the legal limits of the BOC group relationship are the key constraints. It appears to be an investment-grade aircraft leasing credit consistent with the A- rating shown in company materials, but individual bond investment requires separate confirmation of market spreads, bond terms, the legal nature of BOC support and aircraft residual value risk.
