1. Purpose and Treatment

This report organises the discussion on AFFIN Bank Berhad in a way that supplements the reading of the existing reports. The items covered here are a summary of additional research questions, working hypotheses used in the responses, and items for future verification. They do not adopt claims made in the discussion as newly verified facts.

The starting point already confirmed in the existing reports is that AFFIN is on an improving trend as a mid-sized Malaysian bank, while not being a bank with as deep a deposit franchise as the larger banks. In its 1Q2026 results, loans and financing, NII, and fee-related income increased, but customer deposit growth did not keep pace with loan growth, and the CASA ratio remained materially lower year on year. In addition, the sharp increase in credit impairment allowance, the decline in the CET1 ratio, and the seasoning risk associated with the high-growth portion of Enterprise Banking remain continuing monitoring points.

The central focus of this discussion was not whether AFFIN should be viewed as a bank in immediate danger, but rather to pre-define early-warning lines at which the existing view of an improving mid-sized bank would begin to break down. Accordingly, this report does not set out a final investment view or trading recommendation. It organises combinations of indicators to check over the next several quarters, unresolved items, and potential future items for transfer to issuer_notes.md.

2. Analytical Read-Through from the Discussion

The read-through from the overall discussion was that AFFIN’s downside is more likely to appear first as deterioration in funding quality and earnings quality than as a sudden near-term capital shortfall or liquidity crisis. Specifically, if loan growth continues to exceed deposit growth, recovery in the CASA ratio stalls in the 25-27% range, NIM declines, and impairment remains elevated at the same time, AFFIN’s growth story would shift from “a temporary mix deterioration that can be repaired” to “RWA expansion without low-cost deposits.”

Within this read-through, the items already confirmed in the existing reports are that loan growth materially exceeded deposit growth as of 1Q2026; the CASA ratio improved from end-FY2025 but remained low year on year; credit impairment allowance increased sharply; CET1 declined to 12.5%; LCR remained high; and the Sarawak state government becoming the largest shareholder has both support-expectation and strategic-change dimensions.

By contrast, it remains a discussion-level hypothesis whether these items will lead to a structural deterioration in growth quality. In particular, it is still unconfirmed whether the high growth in Enterprise Banking will come with transactional deposits, fee income, and risk-adjusted returns, or whether it will later add only credit costs and RWA. Sarawak-related business would be credit-positive if it brings low-cost deposits and high-quality corporate relationships, but it would become event risk if it is skewed towards policy-oriented regional development and SME lending.

3. Organisation of Q&A Items

3.1 Loan Growth and Funding Quality

The intent of the first question was to distinguish whether AFFIN’s loan growth, particularly the high growth in Enterprise Banking, is good-quality growth supported by a low-cost and sticky deposit base, or growth dependent on higher-cost funding alongside a declining CASA ratio. The PM’s concern was that if deposit costs stay elevated while CASA recovery fails to progress, and NIM pressure and rising credit costs emerge at the same time, PBT and internal capital generation could weaken faster than expected.

The main response was that, at this stage, there is insufficient evidence to conclude immediately that AFFIN’s growth is poor-quality growth, but the quality of loan growth remains untested. As of FY2025, profit, loans, deposits, and asset quality had improved simultaneously, and AFFIN was not clearly a stressed bank. On the other hand, in 1Q2026, loans and financing grew much faster than customer deposits, and although the CASA ratio recovered from end-FY2025, it remained materially lower year on year. Therefore, whether growth is accompanied by low-cost deposits needs to be checked through deposit growth, CASA balances, the loan-to-deposit ratio, and NIM from 2Q2026 onwards.

The follow-up discussion concluded that early-warning triggers should be based on combinations of indicators rather than a single metric. The first practical trigger would be a combination in which loan growth continues to exceed deposit growth for two to three quarters, the CASA ratio stagnates in the 25-27% range, and a decline in NIM or sluggish PBT growth is confirmed. If this is accompanied by persistently high impairment or a further decline in CET1, the discussion was that this should be viewed not as a mere deterioration in funding mix but as the beginning of a narrowing of rating headroom.

The credit implication is that AFFIN’s risk lies less in the absolute level of LCR or the total capital ratio and more in whether growth without low-cost deposits erodes earnings quality. If the loan-deposit gap narrows, CASA recovers from the high-20% range towards 30%, and NIM is maintained, the issue would remain a temporary mix deterioration. Conversely, if CASA stalls in the 25-27% range, reliance on higher-cost fixed deposits, NID, and wholesale funding increases, and NII growth no longer keeps pace with loan growth, the quality of growth needs to be viewed more cautiously.

3.2 Capital Headroom and Management’s Financial Policy

The intent of the next question was to confirm whether, amid the decline in CET1 in 1Q2026, AFFIN has sufficient capital headroom to support its growth strategy, dividend policy, and rating-maintenance policy. The PM’s focus was not only whether the bank remains above regulatory minimums, but also at what point capital becomes a constraint rather than a source of growth capacity if loan growth, increased impairment, dividends, and AT1/Tier 2 issuance overlap.

The main response was that AFFIN is not currently an undercapitalised bank, but capital headroom has narrowed from end-FY2025. The 1Q2026 CET1 ratio was 12.5%, still at an adequate level, but it declined from 13.4% at end-FY2025. It was emphasised that the RM500m AT1CS issuance supports the total capital ratio but does not directly strengthen CET1, and therefore AT1/Tier 2 issuance should not be equated with a recovery in common-equity capital.

The follow-up discussion concluded that the priority management places on “continued growth, dividend maintenance, rating maintenance, and CET1 defence” should be assessed through actions rather than statements. The key point to watch is whether, in a phase where CET1 remains in the low-12% range and impairment remains elevated, management slows loan growth, restrains dividends, tightens RWA management, or instead relies only on AT1/Tier 2 to supplement total capital. If CET1 does not stabilise in the low-12% range for at least two quarters, elevated impairment and continued loan growth overlap, and there is limited explanation of dividend restraint or RWA management, this was viewed as a signal of transition towards capital constraint.

The credit implication is that AFFIN’s capital issue is not “whether the current CET1 ratio is at a dangerous level,” but “whether management demonstrates the willingness and means to protect CET1.” If CET1 recovers to around 12.5-13%, or at least stabilises around 12.5%, impairment normalises, and dividends are linked to the capital level, capital can be viewed as a buffer supporting growth. If CET1 begins moving below 12%, loan growth and dividends are not restrained, and only the total capital ratio is maintained through AT1/Tier 2, the quality of loss-absorption buffers should be viewed as deteriorating even from the perspective of senior creditors.

3.3 Asset Quality and the Increase in 1Q2026 Impairment

The intent of the asset-quality question was to confirm whether AFFIN’s asset quality can be viewed as improving based only on the decline in the GIL ratio at end-FY2025, or whether there remains a risk that credit costs will surface with a lag in high-growth segments. The focus was particularly on which areas among Enterprise Banking, SME, Islamic Banking, and household lending could generate Stage 2 loans, arrears, rescheduling, and new impaired loans.

The main response was that the GIL ratio alone is a lagging indicator. The GIL ratio at end-FY2025 improved to 1.64%, which is confirmed in the existing reports as a support for asset quality. However, in 1Q2026, while the GIL ratio improved year on year, it rose to 1.75% compared with end-FY2025, and credit impairment allowance increased sharply. In addition, impairment increases in Islamic Banking pressured PBT, confirming that credit costs affected earnings in at least some segments.

The follow-up discussion distinguished the conditions under which the 1Q2026 impairment increase should be viewed as “a conservative one-off provision” from those under which it should be viewed as “the beginning of credit deterioration in the growth portfolio.” To view it as a one-off provision, Stage 2 must not have increased materially, 30-day-plus arrears and rescheduling / modification must not have increased, new impaired loans must be limited to specific borrowers, impairment must normalise from 2Q2026 onwards, and the GIL ratio must not deteriorate significantly from around 1.75%. Conversely, if Stage 2, 30-day-plus arrears, and rescheduling deteriorate simultaneously in Enterprise Banking or Islamic Banking, and impairment remains elevated for at least two quarters, the holding risk should be reassessed without waiting for a full-scale rise in the GIL ratio.

The credit implication is that deterioration in AFFIN’s asset quality may appear in the sequence of increases in Stage 2, arrears, and rescheduling; persistently high impairment; a reversal and increase in the GIL ratio; and weaker PBT and CET1 generation capacity. The first portfolio to watch is Enterprise Banking, which grew rapidly in FY2025, followed by Islamic Banking, where impairment pressured earnings in 1Q2026. Community Banking exposures such as mortgages, auto loans, and cards were positioned not as the area likely to break first abruptly, but as a secondary risk that may affect results with a lag if household burden or property-market weakness persists.

3.4 Sarawak State Government Becoming the Largest Shareholder and Strategic Event Risk

The intent of the shareholder-structure question was to confirm whether the Sarawak state government becoming AFFIN’s largest shareholder is a stabilising factor for AFFIN’s credit profile, or a medium-term event risk through accelerated growth, dividend demands, policy-oriented lending, M&A, and other channels. The PM’s concern was not the shareholder name itself, but how the involvement of a state-government-related shareholder affects AFFIN’s deposit franchise, customer base, capital policy, and risk management.

The main response was that the Sarawak state government’s involvement is a potential credit positive, but actual evidence still needs to be confirmed. If a state-government-related shareholder acts as a long-term anchor and transactions with the state government, GLCs, civil servants, strong local corporates, and related parties increase together with CASA, payments, fee income, and high-quality corporate relationships, this could supplement AFFIN’s weakness as a mid-sized bank, namely its deposit franchise. On the other hand, if only loans and RWA increase against a backdrop of state-related business, regional development, and SME support, without CASA or fee income, the Sarawak strategy would become growth pressure rather than a credit positive.

The follow-up discussion organised KPIs for checking Sarawak-related business. The first is Sarawak-related CASA, payroll accounts, settlement accounts, cash management, and average deposit cost. The second is fee income, including advisory, trade finance, cash management, wealth management, and project finance arrangement fees. The third is the industry mix, collateral, risk weights, RWA density, and risk-adjusted returns of Sarawak-related loans. The fourth is concentration in the state government, state GLCs, specific projects, specific regions, and specific sectors. The fifth is Sarawak-related Stage 2, 30-day-plus arrears, rescheduling, and new impaired loans.

The credit implication is that the Sarawak state government becoming the largest shareholder should not be treated as an explicit guarantee or unconditional support. Support assessments by RAM and other agencies, as well as market expectations, are useful items to check, but they are not substitutes for issuer-level credit strength. If Sarawak-related CASA increases, the CASA ratio improves from the high-20% range towards 30%, deposit growth moves closer to loan growth, and fee income and risk-adjusted returns accompany this growth, it would be credit-positive. Conversely, if policy-oriented lending, concentrated exposures, a decline in CET1, persistently high impairment, and an increase in GIL appear at the same time, the shareholder strategy should be treated as medium-term event risk.

3.5 Liquidity and Market-Funding Resilience

The intent of the final question was to confirm whether AFFIN’s liquidity and market-funding resilience can be adequately assessed based only on a high LCR in normal times. The PM’s concern was the stage at which rising funding costs or weaker refinancing terms would feed through into issuer credit strength if deposit competition, a lower CASA ratio, reliance on subordinated capital and AT1 issuance, and risk-off sentiment across the Malaysian banking market overlap.

The main response was that AFFIN does not face an immediate liquidity crisis, but LCR alone cannot measure funding quality. The LCR at end-FY2025 was high, indicating strong short-term liquidity. However, given that loan growth materially exceeded deposit growth in 1Q2026 and the CASA ratio was low year on year, the key issue is not cash-flow funding itself but the cost at which funding is being raised. AFFIN has market access and can issue AT1/Tier 2 instruments, but weaker issuance terms would pressure profitability and capital-policy flexibility.

The follow-up discussion confirmed the first triggers for judging that funding-quality deterioration is beginning to affect credit strength even while LCR remains high. In practical terms, the first warning line is the three-point combination of loan growth continuing to exceed deposit growth, the CASA ratio stagnating in the 25-27% range while reliance on high-cost deposits, NID, and wholesale funding increases, and a decline in NIM or sluggish PBT growth being confirmed. If this is accompanied by persistently high impairment, a decline in CET1, and weaker AT1/Tier 2 issuance terms, it should be treated not as a mere deterioration in funding mix but as narrowing rating headroom.

The credit implication is that AFFIN’s liquidity risk is more likely to surface first as earnings pressure and reduced capital flexibility than as a funding crisis. Even if LCR is adequate from a regulatory perspective, if CASA declines again towards around 25%, customer deposit growth fails to keep pace with loan growth, and NIM decline, persistently high impairment, and CET1 decline occur simultaneously, there would be clear deterioration pressure on issuer credit strength. Wider new-issue coupons or spreads for AT1/Tier 2 should then be treated as confirmation that the market has begun to price in the same concern.

4. Continuing Follow-Up Items

The most important follow-up item is the gap between loan growth and deposit growth. It is already confirmed that loan growth materially exceeded deposit growth in 1Q2026, and if this continues for two to three quarters while the CASA ratio stagnates in the 25-27% range, the quality of growth needs to be reassessed cautiously. The next materials to check are quarterly results materials, deposit breakdowns, the loan-to-deposit ratio, and the trend in CASA, fixed deposits, NID, and wholesale funding.

The second follow-up item is whether the recovery in the CASA ratio is genuine. It is already confirmed that the 1Q2026 CASA ratio improved from end-FY2025 but remained materially lower year on year. It is still unconfirmed whether Sarawak-related deposits or Enterprise Banking transactions are contributing to an increase in CASA, and the key question will be whether CASA returns towards 30% or stalls in the 25-27% range.

The third follow-up item is the seasoning risk of high-growth loans in Enterprise Banking. It is confirmed that Enterprise Banking grew rapidly in FY2025, but its industry mix, collateral, risk grades, share of new customers, and arrears by vintage are unconfirmed. If Stage 2, 30-day-plus arrears, rescheduling, and new impaired loans begin to increase from this segment, caution is warranted without waiting for a full-scale increase in the GIL ratio.

The fourth follow-up item is whether the increase in credit impairment allowance in 1Q2026 is temporary. It is confirmed that impairment increased materially in 1Q2026 and also pressured Islamic Banking PBT, but it is unconfirmed whether the source was Enterprise Banking, Islamic Banking, household lending, or specific large borrowers. If impairment remains elevated from 2Q2026 onwards and is accompanied by increases in Stage 2, arrears, and new impaired loans, questions would arise over the quality of growth lending.

The fifth follow-up item is CET1 defence and capital policy. It is confirmed that CET1 declined in 1Q2026 and that AT1 issuance supplements total capital but does not directly strengthen CET1. In a phase where CET1 remains in the low-12% range, it is necessary to confirm whether AFFIN restrains loan growth, adjusts dividends, and manages RWA, or instead relies on AT1/Tier 2.

The sixth follow-up item is the quality of Sarawak state government-related business. It is confirmed that the Sarawak state government became the largest shareholder, but it is unconfirmed whether this is translating into CASA, payments, fee income, and high-quality corporate relationships. If Sarawak-related lending increases while contributions to CASA and fee income are not visible, and this is accompanied by CET1 decline or persistently high impairment, the shareholder strategy would become medium-term event risk rather than a credit positive.

The seventh follow-up item is liquidity risk viewed through funding quality rather than LCR. It is confirmed that LCR was high at end-FY2025, but even with a high LCR, liquidity risk can surface as earnings pressure if CASA stagnation, reliance on high-cost funding, and NIM decline overlap. It is necessary to check the loan-to-deposit ratio, NSFR, deposit costs, NID and wholesale funding balances, and new-issue terms and secondary-market spreads for AT1/Tier 2.

5. Potential Future Items for Transfer to issuer_notes.md

issuer_notes.md will not be updated in the preparation of this report. However, at the time of the next issuer_summary, issuer_flash, or issuer notes update, the following items should be considered as candidates for transfer as continuing monitoring items.

• AFFIN is in a phase where loan growth is exceeding deposit growth, and if growth without CASA recovery continues, pressure could emerge on NIM, PBT, and CET1 generation capacity through deterioration in funding quality.
• Sustained recovery in the CASA ratio is a key confirmation point for AFFIN’s growth story. If it stagnates in the 25-27% range, loan growth needs to be viewed as RWA expansion without low-cost deposits.
• The high-growth portion of Enterprise Banking has a seasoning lag, and the GIL ratio alone may not capture credit deterioration. Priority should be given to checking leading deterioration in Stage 2, 30-day-plus arrears, rescheduling, and new impaired loans.
• It is unconfirmed whether the increase in impairment in 1Q2026 is temporary. If it remains elevated from 2Q onwards and leading indicators deteriorate in Enterprise Banking or Islamic Banking, questions would arise over the quality of growth lending.
• If CET1 remains in the low-12% range, it will be important whether AFFIN prioritises CET1 defence over growth and dividends. AT1/Tier 2 issuance alone should not be viewed as CET1 recovery.
• The Sarawak state government becoming the largest shareholder would be credit-positive if accompanied by CASA, payments, and fee income, but would become medium-term event risk if it is skewed towards RWA expansion centred on regional development and SME lending.
• AFFIN’s liquidity risk may appear as earnings pressure through CASA stagnation, reliance on high-cost funding, and NIM decline before any decline in LCR.

6. Unresolved Items

The most important unresolved item is deposit quality. Additional confirmation is needed on the composition of CASA, fixed deposits, NID, wholesale deposits, money market funding, and financial-institution deposits; average funding cost; actual Sarawak-related CASA; and the contribution of Enterprise Banking transactional deposits.

For asset quality, disclosure is needed on Stage 2 loans / financing, 30-day-plus arrears, 60-day-plus arrears, rescheduled and modified loans, new impaired loans, recoveries, write-offs, the GIL ratio by Enterprise Banking / Islamic Banking, sector-level watchlists, and arrears by vintage. It also remains unconfirmed which portfolio generated the RM68.9m of impairment in 1Q2026.

For capital policy, unresolved items include the CET1 level management wants to maintain, its dividend-adjustment policy when CET1 declines, its policy for restraining RWA growth, future AT1/Tier 2 issuance plans, issuance terms, and explicit constraints related to rating maintenance.

For Sarawak-related business, unresolved items include actual transaction volume with the state government, GLCs, civil servants, SMEs, and local corporates; CASA contribution; fee income; RWA density; risk-adjusted returns; regional and sector concentration; and the presence or absence of Stage 2 or rescheduling. The Sarawak state government’s involvement has not been confirmed as an explicit debt guarantee or loss-absorption commitment.

For market funding, unresolved items include NSFR, the loan-to-deposit ratio, the composition of liquid assets, secured-funding capacity, room to access central bank liquidity, new-issue coupons for AT1/Tier 2, secondary-market yields, spreads versus similarly rated and larger banks, investor demand, and price movements during risk-off periods across the Malaysian banking sector.
