1. Treatment of This Report

This report organises the discussion dated 2026-05-29 as a supplementary note for reading TNB’s existing issuer summary. In the discussion, information and hypotheses described as additionally confirmed were presented on topics such as monthly AFA operation, government compensation, short-term borrowings, RP4 capex, RAB recovery, and decarbonisation investment. However, this report does not adopt the discussion responses themselves as newly verified facts. It separates issues already confirmed in the existing report, assertions and hypotheses raised in the discussion, and unverified items that should be checked going forward.

The foundation already confirmed in the existing issuer summary is that TNB is Malaysia’s core government-related and regulated electric utility, supported by IBR/RP4/AFA, high ratings, government linkage, and a broad electricity supply base. At the same time, FY2025 operating cash flow and capex were broadly similar in size, and the speed of AFA cash conversion, refinancing from 2026 onward, recovery of RP4 investments, foreign-currency debt, and terms of individual bonds remain continuing monitoring items. Government linkage provides credit support, but should be distinguished from an explicit government guarantee on all debt.

2. Analytical Read-Through from the Discussion

The Q&A converges on the view that TNB should not be read only as a “stable regulated utility protected by regulation”, but rather as a highly indebted utility that is protected by regulation and government support while remaining sensitive to bridge financing until cash recovery, unavoidable capex, and refinancing markets. The entry point for credit deterioration is framed less as a temporary decline in power demand and more as a pathway in which fuel costs, FX, tariff restraint, and the timing of government compensation overlap and appear in operating cash flow, receivables and contract assets, short-term borrowings, and liquidity.

The discussion raises three important hypotheses. First, AFA is an institutional improvement over ICPT, but it is not complete immediate cash protection; if political tariff restraint or compensation delays occur, TNB may temporarily bear the funding burden. Second, capex related to RP4, decarbonisation, and grid reinforcement may partly be recovered as regulated assets, but cash outflows come first, and the lag before RAB inclusion, tariff reflection, PPA monetisation, and subsidy receipt may pressure financial metrics. Third, refinancing risk may become visible in the market less as “inability to raise funding” and more as prolonged high-cost funding, shorter tenors, and reliance on short-term borrowings, delaying improvement in FFO/debt coverage and gearing.

These are not conclusions for investment judgment, but candidate issues to be tested in the next quarterly disclosures, rating agency comments, regulatory materials, and TNB’s borrowing- and capex-related disclosures.

3. Organisation of the Q&A Content

3.1 Fuel Cost, FX, and Tariff Recovery Lag After AFA Introduction

• Question intent: The question was intended to confirm how much TNB’s cash conversion risk has declined under RP4/AFA in a scenario where coal and gas prices, MYR depreciation, higher power purchase costs, and tariff restraint overlap. In particular, the focus was not on recoverability in the income statement, but on the entry point of unrecovered amounts, receivables and contract assets, short-term borrowings, and deterioration in operating cash flow.
• Key response points: The existing report treats AFA as an institutional improvement that accelerates the pass-through of fuel cost and FX fluctuations compared with ICPT. At the same time, the discussion response stated that the specific amount of operating cash flow pressure and the range of increase in short-term borrowings cannot be confirmed from public materials alone, and that even with AFA, if tariff and subsidy recovery lags overlap, the issue may surface first as a short-term liquidity risk.
• Follow-up: The follow-up question asked when TNB would begin to be viewed as exposed to subsidy and recovery-delay risk if the government or regulator prioritises consumer tariff restraint even while AFA is functioning institutionally. The discussion response cited signs such as actual billings being restrained despite the need for an AFA surcharge, delays in receipt even after government compensation or fund replenishment is announced, increases in receivables, contract assets, and government-related receivables, deterioration in short-term borrowings and liquidity, and rating agencies beginning to focus more on compensation timing than on the institutional improvement represented by AFA.
• Credit implication: The implication consistent with the existing report is that TNB’s downside is likely to appear first in operating cash flow and short-term liquidity. As an additional hypothesis from the discussion, AFA may be effective as “earnings protection”, but may become insufficient as “immediate cash protection” if political tariff restraint intervenes. In the next review, it will be necessary to look at the simultaneous movements in unrecovered AFA balances, trade receivables, contract assets, government-related receivables, short-term borrowings, and cash and deposits.

3.2 Medium-Term Capex Burden and Scope to Defer Investment

• Question intent: Given that FY2025 operating cash flow and capex were broadly similar in size, the question was intended to confirm how equipment renewal, transmission and distribution networks, and renewable energy investment over the next three to five years may affect financial leverage, short-term borrowing capacity, and rating headroom.
• Key response points: As confirmed in the existing report, TNB is an asset-intensive utility, and its FY2025 capex burden was heavy. The discussion response stated that if medium-term capex continues, it may be difficult to fund it solely from internal cash generation, and external funding such as short-term borrowings, bonds, and sukuk may be needed. At the same time, the year-by-year and project-by-project medium-term capex plan, funding structure, and scenarios under higher interest rates were treated as unconfirmed.
• Follow-up: The follow-up question asked about the ratio between capex that could be postponed or reduced under stress and capex that is unavoidable due to regulation, supply obligations, or government policy. The discussion response stated that power plant renewal and transmission and distribution network renewal are highly essential for stable supply, while some renewable energy investment may have an element of discretion, but the specific ratio remains unconfirmed.
• Credit implication: For credit purposes, the key variables are not only total capex, but the ratio of unavoidable capex and the timing of recovery. If unavoidable investment is large, deterioration in operating cash flow is more likely to be absorbed through additional borrowing rather than capex cuts. This can be positioned as translating the existing summary’s issue — that even investments recoverable as regulated assets involve spending first and recovery later — into more practical monitoring items.

3.3 Government and Regulatory Support: Credit Support or Policy Burden

• Question intent: The question was intended to confirm whether TNB’s government linkage and regulatory framework function as pure credit support even under stress, or whether TNB temporarily bears a policy burden through tariff restraint, delayed subsidy payments, and policy-led investment.
• Key response points: The existing report treats government linkage, IBR/RP4/AFA, and high ratings as credit supports, while indicating that these should not be conflated with an explicit government guarantee. The discussion response stated that government and regulatory involvement normally supports cost recovery and market access, but under stress may turn into a temporary balance sheet burden for TNB through tariff restraint, the timing of compensation payments, and front-loaded policy investment.
• Follow-up: The follow-up question asked how TNB would fund bridge financing if AFA or government compensation is recoverable but cash receipt is delayed. While noting that the company’s formal internal order of priority is unconfirmed, the discussion response presented the hypothesis that a delay of several months would likely be absorbed through available liquidity, short-term bank borrowings, and short-term or marketable funding such as CP/MTN/sukuk, while capex deferral would tend to rank lower.
• Credit implication: The scenario requiring the most caution is not the disappearance of government support, but a phase in which support remains in place while TNB bears bridge financing until payment is received. Whether the market treats this as a temporary working-capital swing or prices it into spreads as a more permanent policy burden will depend on the duration of unrecovered amounts, whether short-term borrowings reverse, the track record of government compensation receipts, and rating agency comments.

3.4 Refinancing from 2026 Onward and Resilience to Higher Interest Rates

• Question intent: The question was intended to confirm how far refinancing from 2026 onward, higher interest rates, and deterioration in market funding conditions may affect TNB’s credit quality, given its high debt level and large capex.
• Key response points: The existing summary confirms RM11.09bn of maturities in 2026, RM10.65bn of cash and cash equivalents at FY2025-end, and RM12.84bn of deposits, bank balances, and cash, while leaving unused committed lines and details of short-term debt as unconfirmed. The discussion response stated that TNB’s AAA/P1 ratings and access to domestic and overseas markets are supports, but that if large capex, AFA cash conversion lag, and high-cost refinancing overlap, the impact could become visible over the medium term through higher short-term borrowings, shorter funding tenors, a higher interest burden, and lower FFO/debt coverage.
• Follow-up: The follow-up question asked which measures TNB would prioritise to protect financial metrics under refinancing stress: dividend restraint, capex deferral, non-core asset sales, tenor extension through long-term bonds or sukuk, use of bank lines, or requests for additional compensation. The discussion response, while noting that the official policy is unconfirmed, presented the hypothesis that the initial response would be liquidity on hand, bank facilities, and short-term market funding, while capex deferral and dividend restraint would likely rank lower due to constraints from stable supply and policy investment.
• Credit implication: Refinancing risk should be viewed less as a near-term cash crunch and more as a risk that funding remains available but high-cost funding, shorter tenors, and reliance on borrowings persist, delaying improvement in financial metrics. Early warning indicators are the short-term debt ratio, reliance on bank borrowings, CP/MTN/sukuk outstanding, average tenor, interest burden, cash and deposits on hand, and whether rating agencies begin to emphasise debt burden rather than liquidity.

3.5 Decarbonisation and Renewable Energy Investment and RAB Recovery

• Question intent: The question was intended to confirm how reliably renewable energy expansion, reinforcement of transmission and distribution networks, storage and grid stabilisation, and the phased reduction of coal-fired power can be recovered through regulated tariffs, RAB, government subsidies, and long-term contracts, and whether shareholders and creditors are left with front-loaded burdens.
• Key response points: The existing summary treats renewable energy and overseas businesses as pillars of long-term transition, but states that near-term credit assessment centres on the domestic Malaysian regulated power business and funding burden. The discussion response stated that transmission and distribution networks and grid reinforcement investments are relatively likely to be recovered as regulated capex under RAB/RP4, whereas generation, overseas renewable energy, and coal-reduction-related investments depend on PPAs, power sale prices, subsidy schemes, project finance terms, and treatment of undepreciated assets, and therefore cannot be assumed to be recoverable through RAB as a whole.
• Follow-up: The Q&A presented a three-part classification for decarbonisation investment. The first is grid investment recoverable through RAB, the second is renewable energy investment backed by PPAs or project revenues, and the third is policy transition costs such as early coal retirement and repowering. The third category in particular was described as policy-necessary but prone to opaque recovery mechanisms.
• Credit implication: Decarbonisation risk lies less in renewable energy investment itself and more in the possibility that policy-required investment is implemented upfront while RAB inclusion, tariff reflection, subsidy receipt, and PPA monetisation are delayed. It will be necessary to confirm approved regulated capex under RP4/RP5, Actual RAB, allowed returns, the scope of RAB inclusion for BESS and grid investment, contractual terms for LSS/CRESS/CGPP/overseas renewable energy, and compensation and undepreciated asset treatment for early coal retirement.

4. Issues Confirmed in the Existing Report and Additional Issues from the Discussion

The issues confirmed in the existing report are as follows.

• TNB is Malaysia’s core regulated utility and government-related issuer, with credit quality supported by IBR/RP4/AFA, high ratings, and government linkage.
• AFA is an institutional improvement that shortens the cost pass-through lag compared with ICPT, but fuel cost, FX, and tariff recovery lags do not disappear completely.
• FY2025 earnings improved, but operating cash flow and capex were broadly similar in size, leaving limited headroom after investment.
• 2026 maturities, foreign-currency debt, unused committed lines, and guarantees and covenants on individual bonds remain continuing items for confirmation.
• Government linkage must be distinguished from an explicit government guarantee.

Issues presented as additional points in the discussion but treated as unverified in this report are as follows.

• The approval process when AFA exceeds certain thresholds, the discretion of the government and regulator, and the possibility of divergence between the calculated AFA amount and the amount actually billed.
• Historical recovery record for the government-borne portion of ICPT, and quarterly trends in short-term borrowings and ICPT/AFA receivables.
• The levels and interpretation of lease-adjusted debt, gearing, and FFO/debt coverage in rating comments by RAM and others.
• Investment recovery design under RP4, including contingent capex, regulated capex, Actual RAB, and the 7.3% regulated return.
• Off-RAB risks related to renewable energy, BESS, CRESS, CGPP, overseas renewable energy, and coal-reduction-related investments.

These are candidates for deciding whether to incorporate into the existing source registry when official materials, rating reports, and regulatory materials are next reviewed.

5. Candidate Items for Transfer to issuer_notes

The following are candidate items that could be considered for transfer to the “follow-up on management strategy, investment plan, and financial policy” section of issuer_notes.md in a future update. The issuer notes have not been updated as of the preparation date of this report.

• Continue monitoring the cash conversion speed of AFA calculation and government compensation. In particular, check for simultaneous deterioration in unrecovered AFA balances, delays in government compensation receipts, trade receivables, contract assets, and short-term borrowings.
• Continue checking the medium-term capex burden and refinancing capacity. Prioritise the 2026-2028 capex plan, the mix of borrowings, bonds, and sukuk, and unused committed lines.
• Follow the recovery timing and scope of RAB inclusion for renewable energy and decarbonisation investment. Separately confirm transmission and distribution/grid investment and off-RAB investments related to generation, overseas renewable energy, and coal reduction.
• Continue monitoring short-term borrowings and reliance on market funding. Check changes in CP/MTN/sukuk outstanding, average tenor, interest rates, and liquidity on hand together with the AFA recovery lag.
• Continue assessing the impact of policy-priority capex on financial metrics. Track requests from the government and regulator to front-load renewable energy and grid investment, and approved regulated capex under RP4/RP5.

6. Unconfirmed Items and Materials to Review Next

In this discussion report, assertions in the discussion have not been reverified against external sources. Accordingly, the next items to confirm are as follows.
