1. Positioning and Treatment

This report is a supplementary organisation of the discussion, read against the existing AIA Group issuer_summary. The discussion here should be read by distinguishing among hypotheses raised in the discussion, points already confirmed in existing reports, and items that remain unverified. Views raised in the discussion should not be treated as newly confirmed AIA disclosures or new rating-agency conclusions.

The framework already confirmed in the existing issuer_summary is that AIA is supported by a broad Asian life and health insurance franchise, a high Group LCSM coverage ratio, substantial holding company financial resources, and AA-/A1/AA- level issuer ratings. At the same time, the contribution from Hong Kong and Mainland China, market sensitivity of investment assets and insurance liabilities, capital returns, and structural subordination of holding-company debt need to be analysed separately.

This discussion is positioned as a further refinement of that framework, focusing on the sequence in which deterioration in AIA’s credit strength would likely appear. The central issue is not short-term senior debt repayment risk. Rather, it is where the AA-level cushion and the effective buffer available to holding-company creditors would start to be eroded if slowing growth in Hong Kong and Mainland China, market stress, shareholder returns, subsidiary capital lock-in, and deterioration in sales quality were to occur simultaneously.

2. Overall Reading of the Discussion

One view raised in the discussion was that AIA’s earliest deterioration signals may appear not simply in a decline in VONB, but in the linkage among VONB margin, new business CSM efficiency, CSM variances, UFSG, subsidiary capital flows, and holding company financial resources. AIA currently has strong capital and liquidity, so it would be premature to frame a single-year slowdown in new business or market price volatility as a short-term repayment risk. At the same time, if the quality of growth or the quality of capital mobility deteriorates, this should be treated as a medium-term weakening of the business and capital profile.

As points already confirmed in existing reports, AIA’s shareholder capital ratio, Group LCSM coverage ratio, and holding company financial resources at end-2025 were all high, and its new business metrics in 1Q 2026 were also strong. However, the capital ratio declined in 2025, with shareholder returns and growth in required capital explained as the main drivers. Therefore, it is necessary to look not only at the absolute level of capital, but also at the pace at which capital is used for returns, growth investment, and market movements.

Items that remain unverified include the explicit numerical triggers at which AIA would change its growth investment in Hong Kong and Mainland China, its policy of returning 75% of net FSG, share buybacks, dividend growth, or subsidiary dividend policies. Quantitative information on regional capital flows, solvency headroom by major subsidiary, persistency by product, claims experience, sales complaints, and regulatory sanctions also cannot be sufficiently confirmed from this discussion alone.

3. Summary of Q&A

Research Question 1: Through What Channels Does Hong Kong / Mainland China Dependence Matter?

The purpose of the question was to assess whether, if Hong Kong Mainland Chinese Visitor demand and Mainland China’s low interest rates, product guarantees, sales quality, and regulatory capital constraints were to deteriorate at the same time, the impact would be confined to lower VONB or could extend to CSM, UFSG, Group LCSM, subsidiary dividends, and holding company financial resources.

The key point of the response was that the initial deterioration would likely appear in VONB, ANP, VONB margin, and new business CSM, but the more important credit issue is whether this then feeds through to UFSG, net FSG, subsidiary capital flows, and HFR. A merely temporary slowdown in sales would be unlikely to translate directly into short-term senior debt repayment risk, given AIA’s high capital, diversification, and HFR. By contrast, if simultaneous deterioration in Hong Kong and Mainland China persisted for several years and undermined product profitability, sales quality, and assumptions for the in-force book, it would damage the stock of future profits and excess capital generation.

The follow-up explored whether AIA would treat deterioration in Hong Kong MCV demand or the Mainland China business as a temporary new business slowdown, or as a structural change significant enough to alter product mix, sales channels, capital allocation, and subsidiary dividend policy. The discussion characterised AIA at present as not viewing Hong Kong and Mainland China as markets to be reduced. Rather, AIA is understood as seeking to continue growth by capturing both MCV and domestic demand in Hong Kong, and by using Premier Agency, selective bancassurance, new regional expansion, repricing, and protection products in Mainland China. However, the level at which AIA would shift its judgement from “temporary” to “structural” remains unverified.

The credit implication is that it is insufficient to look only at year-on-year VONB in Hong Kong and Mainland China. If VONB declines but margin and new business CSM are preserved, and free surplus used to fund new business does not rise excessively, the issue is closer to a revision of growth expectations. By contrast, if VONB margin declines, new business CSM slows, CSM variances deteriorate, UFSG declines, and subsidiary capital flows fall at the same time, this becomes an issue that erodes medium-term rating headroom even within AIA’s strong issuer credit profile.

Research Question 2: Resilience to Combined Market Stress

The purpose of the question was to assess whether AIA could maintain a sufficient Group LCSM coverage ratio, shareholder capital ratio, UFSG, and HFR even if lower interest rates, wider credit spreads, weaker equity markets, and currency movements occurred simultaneously. A particular focus was whether capital-market stress would remain an accounting fluctuation or would have a substantive impact on shareholder-return capacity and rating headroom.

The key point of the response was that AIA has substantial buffers against single shocks, but combined stress should not be viewed solely as a temporary accounting movement. The Group LCSM coverage ratio, shareholder capital ratio, UFSG, and HFR at end-2025 were all strong. At the same time, market stress can affect investment variances, free surplus, net FSG, and HFR. In particular, if deterioration in investment return variances and other items, a decline in free surplus, lower subsidiary capital flows, and continued shareholder returns occur simultaneously, the impact may appear first in AA-rating headroom and spread assessment, rather than in short-term liquidity.

The follow-up asked at what stage under market stress AIA would restrain shareholder returns and prioritise the preservation of capital, free surplus, and HFR. The discussion concluded that, based on AIA’s public materials, no explicit return-suspension trigger based on the Group LCSM coverage ratio or free surplus can be confirmed. The discussion then framed AIA’s capital management policy as having two layers: return of 75% of annual net FSG, and additional returns after regular review of the capital position. As a hypothesis, in a stress scenario the first adjustment candidate would be additional share buybacks, followed by the share-buyback component within the 75% return framework, and lastly dividend growth.

The credit implication is that the Group LCSM coverage ratio alone is not sufficient to capture combined stress. The indicators a PM should monitor are total returns relative to net FSG, investment return variances, the post-return balance of free surplus, subsidiary capital flows, and the direction of HFR. Even if LCSM still appears high, if free surplus and HFR decline after returns and capital flows also weaken, the effective cushion available to holding-company creditors becomes thinner.

Research Question 3: Priority Order among Capital Policy, Shareholder Returns, and Growth Investment

The purpose of the question was to assess whether AIA’s capital policy increases downside resilience in its credit profile, or whether it is tilted toward prioritising growth and returns by using the cushion embedded in its high rating. Specifically, the issue was which expenditure would be adjusted first if the 75% net FSG return policy, share buybacks, dividend growth, new business investment, partnerships, and small-scale M&A were all to continue at the same time.

The key point of the response was that AIA’s capital policy is not managed with credit defence as the sole overriding priority. Rather, it is designed to continue growth investment and shareholder returns explicitly, on the basis of strong capital, free surplus, and HFR. However, this is not a policy of unlimited capital deployment. It was characterised as a framework that seeks to combine robust regulatory solvency, profitable new business growth, and shareholder returns. In 2025, shareholder returns pushed down the capital ratio, while the shift in Mainland China toward less capital-intensive products was viewed as evidence of attention to capital efficiency.

The follow-up asked whether stopping additional share buybacks alone would be sufficient to maintain the AA rating. The discussion concluded that, under mild stress, suspending additional share buybacks would have a meaningful defensive effect. However, in a scenario where slowing growth in Hong Kong and Mainland China, market stress, and lower subsidiary capital flows occur simultaneously, that measure alone could become insufficient. Unless the 75% return policy itself, dividend growth, capital-inefficient new business investment, and partnership investments also become more flexible, there may be cases in which declines in free surplus and HFR cannot be halted.

The credit implication is that AIA’s risk should not be assessed only by the presence or absence of additional share buybacks. Even after additional share buybacks are suspended, if dividends remain downwardly sticky, total returns remain high relative to net FSG, and HFR continues to decline after returns, AA-rating headroom narrows. Conversely, if AIA adjusts additional buybacks, buybacks within the 75% return framework, lower-profitability new business investment, and partnership investments in stages, that can be viewed as credit-defensive behaviour.

Research Question 4: Movement of Funds from Subsidiaries to the Holding Company

The purpose of the question was to assess, for creditors of AIA Group Limited as the holding company, under what regulatory, market, and business stresses the movement of funds from insurance subsidiaries to the holding company is most likely to become constrained. The focus was how far HFR and group debt-servicing capacity would be affected if local solvency regulation, dividend restrictions, capital lock-in, and foreign-exchange or remittance constraints were to tighten in key markets such as Hong Kong, Mainland China, Singapore, and Thailand.

The key point of the response was that AIA’s group-wide capital amount and the HFR available to holding-company creditors are not the same thing. AIA’s own disclosures state that the holding company’s ability to pay dividends and meet its debt obligations depends on dividends, remittances, and other payments from operating branches / subsidiaries, and that these are subject to contractual, regulatory, and other restrictions. As of 2025, HFR was substantial and short-term repayment risk was low. However, in a downside scenario, the issue that may emerge first is that “capital exists inside subsidiaries but is hard to upstream to the holding company.”

The follow-up asked how to distinguish whether a decline in capital flows reflects a temporary remittance timing difference or a structural decline in the dividend capacity and regulatory capital headroom of major subsidiaries. The discussion concluded that AIA’s decline in 2025 capital flows, based on company explanation, reflected the reversal of large remittances in 2024 to support share buybacks and cannot immediately be concluded to represent structural deterioration. At the same time, regional capital flows, HKRBC headroom at AIA Co. / AIA International, C-ROSS II headroom at AIA China, and local RBC headroom at AIA Singapore / AIA Thailand remain unverified. Capital lock-in in Hong Kong and Mainland China was identified as the most important monitoring item.

The credit implication is that even if the Group LCSM coverage ratio is high, capital that cannot be converted into HFR is not an immediate cushion for holding-company creditors. A one-year decline in capital flows may be a timing difference. However, if capital flows decline for multiple consecutive years, HFR falls after shareholder returns, free surplus stagnates, and company explanations increasingly refer to local capital retention or dividend approval constraints, the issue should be treated as structural capital lock-in.

Research Question 5: Franchise Quality and “Low-Quality Growth”

The purpose of the question was to assess whether AIA’s broad Asian franchise can maintain underwriting quality, sales quality, and brand trust even if economic recession, medical inflation, higher lapse rates, deterioration in sales-channel quality, sales complaints, and regulatory intervention occur simultaneously. The underlying concern is that AIA’s credit strength is rooted not simply in capital ratios, but in its ability to keep originating profitable new business through high-quality distribution channels.

The key point of the response was that AIA’s franchise is currently strong, and that 2025 VONB, VONB margin, new business CSM, OPAT, and UFSG were all solid; there is no confirmed evidence that sales quality or underwriting has already broken down. At the same time, if franchise deterioration occurs, it could feed through to the medium-term business profile and rating assessment via lower VONB margin, slower new business CSM, worse CSM variances, lower persistency, weaker claims experience, and increased sales complaints or regulatory intervention.

The follow-up asked which combination of indicators, rather than the VONB growth rate, should be viewed as warning lines for “low-quality growth” or “business profile deterioration.” The discussion concluded that even if VONB is rising, a simultaneous decline in VONB margin, deterioration in new business CSM / VONB efficiency, worse CSM variances, lower persistency, weaker claims experience, and increased sales complaints or regulatory intervention should be treated not merely as a growth slowdown but as an early sign of structural deterioration. In particular, if AIA shifts toward lower-profitability products or lower-quality sales channels in order to maintain sales volumes, it may be using policy quality and brand trust to manufacture future profits.

The credit implication is that AIA’s strengths should not be viewed as static. In a strong insurer such as AIA, brand, agency force, bancassurance, and the existing customer base may allow headline ANP or VONB to be maintained for some time. However, if profitability, persistency, underwriting, and sales quality deteriorate at the same time beneath the surface, the impact will appear later in future OPAT, UFSG, capital flows, and HFR. Therefore, the deterioration in quality of growth should be monitored before an absolute decline in VONB.

4. Credit Issues by Theme

Deterioration in Hong Kong and Mainland China Would Feed Through in Stages from VONB to HFR

The discussion hypothesis is that deterioration in Hong Kong and Mainland China would first appear in VONB, ANP, VONB margin, and new business CSM. Thereafter, if sales quality, product profitability, lapses, medical claims, guarantee costs, and investment returns affect in-force assumptions, the impact would feed through to CSM variances, CSM release, and UFSG. If net FSG then declines, subsidiary capital flows fall, and HFR declines after shareholder returns, the cushion available to holding-company creditors would also be affected.

Within the scope already confirmed in existing reports, AIA as of 2025 and 1Q 2026 continues to treat Hong Kong and Mainland China as core growth markets. Hong Kong is supported by both MCV and domestic customers, while Mainland China is supported by Premier Agency, selective bank partnerships, repricing, and improved capital efficiency. Therefore, structural deterioration cannot be said to have materialised at present.

What remains unverified is regional new business CSM, regional CSM release, the UFSG contribution from Hong Kong and Mainland China, and the breakdown of subsidiary dividends and capital flows. Without these, the speed at which a VONB slowdown would feed through to HFR cannot be quantified.

Emphasise Post-Return Free Surplus and the Direction of HFR, Rather Than the Height of Capital Ratios Alone

AIA’s Group LCSM coverage ratio and shareholder capital ratio are high, but the discussion concluded that these alone do not fully capture combined stress. Even if LCSM appears high, if investment return variances become significantly negative, free surplus declines after returns, net FSG weakens, and subsidiary capital flows also fall, shareholder-return capacity and rating headroom would come under pressure.

As a confirmed point, AIA has a policy of returning 75% of annual net FSG and also conducts additional share buybacks. Shareholder returns contributed to the decline in the capital ratio in 2025. This has not been characterised as a level that currently impairs credit strength, but it indicates that strong capital headroom is being used not only for preservation but also for shareholder returns and growth investment.

What remains unverified is the level at which AIA would make its return policy more flexible. In the discussion, the adjustment candidates were identified as additional share buybacks first, then share buybacks within the 75% return framework, then capital-inefficient new business investment and partnership investments, and finally dividend growth. However, this is an inference from disclosed policy, not an order explicitly stated by the company.

For Subsidiary Capital Flows, Look Not Only at the Aggregate Amount but Also at Where They Come From

For creditors of AIA Group Limited, what matters is not only the group’s overall insurance financial strength, but whether capital inside subsidiaries can be upstreamed to the holding company. The discussion concluded that local regulatory capital and dividend capacity in Hong Kong AIA Co. / AIA International, Mainland China AIA China, Singapore, and Thailand should be monitored as sources of HFR.

As a confirmed point, AIA’s HFR was substantial at end-2025 and scheduled near-term debt repayments were limited. At the same time, HFR is affected by subsidiary capital flows, investment income, borrowings, dividends, and buybacks. Assets of insurance subsidiaries are first used for policyholder protection and local regulatory capital, so holding-company debt is structurally subordinated.

What remains unverified is the regional breakdown of 2025 capital flows, excess capital by major subsidiary, distributable amounts, local regulatory approvals, and actual remittance capacity under C-ROSS II and HKRBC. Hong Kong may have a large direct impact on HFR because of its scale and core status, while Mainland China requires attention as a capital lock-in risk because of low interest rates, guaranteed products, C-ROSS II, and growth investment.

“Low-Quality Growth” Can Occur Even While VONB Is Rising

The central warning line in the discussion is whether the quality of AIA’s growth is deteriorating even if VONB is increasing. If VONB margin declines, new business CSM growth lags VONB, persistency and claims experience deteriorate, sales complaints or regulatory intervention increase, and shareholder returns or growth investment are nevertheless maintained, the business profile may be deteriorating beneath the surface growth.

Within the scope already confirmed in existing reports, AIA remains strong at present. VONB margin, new business CSM, CSM, and UFSG in 2025 were solid. The emphasis on protection and fee-based products is viewed as positive evidence that AIA is not excessively skewed toward savings products with heavy guarantee burdens.

What remains unverified is persistency, lapse rate, claims ratio, claims inflation, sales complaints, regulatory sanctions, and sales quality by region, product, and channel. These cannot be sufficiently disaggregated from public group-level materials alone, and local disclosures and supervisory data in each market would also be needed.

5. Monitoring / Next Check

In subsequent checks, priority should be given to the following.

• Check VONB, ANP, VONB margin, new business CSM, product mix, the balance between Hong Kong MCV and domestic customers, and repricing and capital efficiency in Mainland China.
• In CSM movement, check new business CSM, CSM release, and CSM variances / operating variances, and assess whether deterioration in new business is feeding into assumptions for the in-force book.
• Check UFSG, net FSG, free surplus used to fund new business, investment return variances, and the post-return balance of free surplus, and assess whether growth, returns, and market movements are consuming capital-generation capacity.
• Check not only the Group LCSM coverage ratio and shareholder capital ratio, but also HFR, subsidiary capital flows, and the post-shareholder-return balance of HFR.
• For shareholder returns, check how far total returns exceed 75% of net FSG, the presence or absence of additional share buybacks, share buybacks within the 75% return framework, and flexibility in dividend growth.
• For subsidiary fund movements, check regional capital flows, HKRBC headroom at AIA Co. / AIA International, C-ROSS II headroom at AIA China, local RBC headroom in Singapore and Thailand, and company explanations regarding dividend approvals or capital retention.
• For franchise quality, check VONB margin, new business CSM / VONB efficiency, persistency / lapse, claims experience, medical inflation, sales complaints, regulatory intervention, and channel-level productivity.

The following are candidate items to consider transferring to “Follow-up on management strategy, investment plans, and financial policy” in issuer_notes.md in subsequent updates. This report itself does not update issuer_notes.md.

• Continue to monitor deterioration in Hong Kong and Mainland China not only through VONB, but also through whether there is any feed-through to new business CSM, UFSG, and subsidiary capital flows. Structural deterioration is not confirmed at present.
• Under market stress, monitor simultaneous deterioration in net FSG, investment return variances, free surplus, and HFR, rather than the Group LCSM coverage ratio alone.
• AIA’s return policy is not currently assessed as impairing credit strength, but if total returns exceed net FSG and HFR declines after returns, this should be treated as a factor reducing AA-rating headroom.
• When subsidiary capital flows decline, distinguish between a one-year remittance timing difference and capital lock-in in core markets such as Hong Kong and Mainland China. Regional capital flows remain unverified.
• Monitor not only the VONB growth rate, but also VONB margin, new business CSM efficiency, persistency, claims experience, and sales quality in combination, in order to identify low-quality growth at an early stage.
• Continue to check whether, in the event of deterioration in Hong Kong and Mainland China, AIA maintains growth investment or narrows its product mix, channels, and capital allocation. Explicit decision triggers remain unverified.

6. Unverified Items

This discussion should not be used to assert the following as new facts.

• If Hong Kong MCV demand declines, how much would be a temporary sales slowdown and how much would feed through to product profitability, CSM, UFSG, and capital flows.
• The quantitative impact of low interest rates, guaranteed products, C-ROSS II capital requirements, and deterioration in sales quality in Mainland China on AIA China’s excess capital and dividend capacity.
• Regional new business CSM, regional CSM release, regional CSM variances, and regional UFSG contribution.
• The Group LCSM coverage ratio, shareholder capital ratio, free surplus, or HFR levels at which AIA would restrain shareholder returns or growth investment.
• Regional capital flows, solvency ratios by major subsidiary, distributable amounts, and the status of local regulatory approvals.
• Persistency by product, lapse rate, claims ratio, claims inflation, sales complaints, mis-selling, regulatory sanctions, and sales quality by channel.
• The quantitative levels at which rating agencies would incorporate deterioration in AIA’s sales quality, claims experience, or continued capital returns into the rating.
