1. Purpose and Treatment

This report preserves the analytical path of an SSC discussion. It is a supplementary discussion record, not a verification of new facts, a rating opinion, or an investment recommendation. The SSC discussion combined information already reflected in the existing issuer materials with analytical hypotheses and indicative warning lines. Unless expressly described below as existing-report context, the proposed thresholds and stress sequences are discussion constructs rather than Guotai Haitong disclosures, covenants, or rating-agency triggers.

The central question was whether the merged group's substantial parent-company regulatory buffers could obscure earlier pressure in collateral, legal-entity liquidity, subsidiary funding, operating flexibility, controls, asset quality, or entity-specific support. The existing issuer summary provides the starting context: at end-March 2026 the parent reported net capital of RMB191.6bn, a risk coverage ratio of 257.41%, LCR of 282.49% and NSFR of 148.18%. Those buffers are important positives, but they do not by themselves demonstrate the location, currency, transferability or unencumbered status of liquidity across the group.

2. Discussion Takeaway

The SSC discussion did not identify a currently established liquidity, capital, control, asset-quality or support failure. Its useful read-through is instead a hierarchy of questions for subsequent issuer work. The quickest market-stress transmission was discussed as the trading-derivatives-repo complex, with margin and stock-pledged financing as the next potentially fast loss channel. Offshore entities were considered more likely to amplify an entity-level liquidity problem than to be the first source of group-wide valuation losses, while leasing was viewed as a slower credit-cost channel.

Across the five questions, the common analytical discipline was to avoid taking a strong parent LCR, a positive consolidated profit figure, municipal-government-related ownership, or an unchanged group name as a substitute for evidence. Credit deterioration would become materially more concerning when two or more channels interact: collateral depletion and shortened repo tenor; earnings weakness and declining parent net capital; a repeated control failure and parent support; correlated losses across multiple businesses; or weak support behaviour coupled with entity-level legal uncertainty.

3. Q&A Discussion Notes

3.1 Market, repo and legal-entity liquidity stress

Question intent. The first question asked which exposures would transmit a simultaneous China equity correction, credit-spread widening and tighter repo haircuts first, and when earnings volatility would become a liquidity or downgrade concern. The follow-up tested a case in which parent LCR remained above 150% while offshore counterparties shortened tenors.

Answer points. The discussion ranked the trading-derivatives-repo complex first because valuation moves, repo collateral revaluation and derivative variation margin can create daily cash needs. Margin and stock-pledged financing were discussed as the next-fastest channel if falling share prices, client concentration or illiquid collateral make liquidation ineffective. Offshore subsidiaries could be the first visible liquidity problem where USD or HKD funding, counterparty limits, collateral calls or cross-border transfer constraints differ from the mainland parent. Finance leasing was treated as normally slower, transmitting through migration, provisions and recoveries rather than daily margin calls.

Existing materials support the need to monitor this distinction: the group has substantial repo funding and market-risk activities, while the parent regulatory metrics remain strong. They do not, however, disclose a complete legal-entity and currency liquidity ladder, unencumbered eligible collateral, haircut sensitivity, derivative peak-margin needs, intercompany transfer limits or a legacy-Haitong risk-book attribution. The discussion therefore did not conclude that a legacy Haitong portfolio is weaker; it identified the attribution and funding structure as unconfirmed.

Follow-up deepening. The follow-up replaced a single LCR test with a joint stress test. It proposed that a pre-rating exposure reduction could be considered if usable unencumbered collateral declined by roughly 25%–30%, a material subsidiary needed parent funding for about 20%–25% of its short-term needs, and parent net capital fell by at least 10% in one quarter. These are internal analytical warning lines only. The underlying point is that LCR can remain high while qualifying liquid assets are in the wrong entity or currency, are unacceptable collateral to a counterparty, or cannot be moved in time.

Credit-analysis implication. Future analysis should give more weight to repo tenor, haircut changes, unencumbered collateral, daily margin requirements, subsidiary funding and currency-specific liquidity than to headline parent LCR alone. Expected parent or municipal support is relevant to longer-horizon default risk, but is not evidence of same-day collateral availability or of legal support for every offshore obligation.

3.2 Weak capital-markets activity, earnings quality and internal capital generation

Question intent. The second question examined whether several quarters of weak turnover, issuance and client risk appetite would turn the enlarged platform's earnings weakness into structural pressure on net capital, leverage and ratings. The follow-up specified a four-quarter downturn with a cost-income ratio above 80% and trading income above 40% of recurring revenue.

Answer points. The discussion viewed post-merger scale, broad business coverage, equity and current regulatory headroom as sufficient to absorb a normal cyclical downturn. It nevertheless emphasised that fee income, margin financing, investment banking and asset-management activity can weaken together, while staff, technology, branch and subsidiary costs adjust more slowly. Trading income can support earnings, but a persistent increase in trading and fair-value income as a share of recurring revenue would weaken the quality and capital efficiency of those earnings.

The existing issuer summary already cautions that 2025 comparatives are distorted by the merger and acquisition-related gains, and that no same-scope pro forma history has been obtained. The SSC discussion added that quantified cost-synergy targets, a recurring post-merger cost-income ratio, the parent-only net-capital bridge, and return on regulatory capital by business remain unconfirmed. Accordingly, it did not treat reported profit as proof of sustainable organic net-capital generation.

Follow-up deepening. The discussion preferred an early management response of balance-sheet reduction, dividend and repurchase restraint, and permanent cost removal; external capital raising was regarded as a backstop rather than evidence of healthy internal generation. Indicative warning lines were recurring revenue down for four quarters, a cost-income ratio above 80% for two quarters, trading/fair-value income above 40% of recurring revenue, parent net capital down at least 5% over 12 months, and no quantified evidence of integration savings. The follow-up argued that management inaction for a further two quarters under those conditions would weaken the assumption that merger synergies are being realised.

Credit-analysis implication. The relevant future test is not absolute reported profit alone. It is whether retained recurring earnings translate into stable or growing parent regulatory net capital after distributions, subsidiary support and risk charges, while market-risk intensity and repo-funded assets are reduced rather than increased.

3.3 Subsidiary integration, risk systems and control effectiveness

Question intent. The third question tested whether incomplete integration could create a credit event through regulatory restrictions, operational losses or repeated capital support even while group earnings and liquidity ratios remained acceptable. The follow-up considered a repeated breach at a core subsidiary and a restriction lasting more than three months.

Answer points. The discussion recognised positive reported milestones: the parent legal-entity transition, major client migration and policy harmonisation were described as substantially completed, and the annual report reported a standard unqualified internal-control audit opinion. It also recorded that subsidiary integration, overlapping-operation rationalisation and the remaining control implementation are not fully demonstrated in public disclosure. Regulatory and disciplinary incidents across several business areas, including a temporary restriction at HuaAn Funds, were treated as reasons for heightened monitoring rather than proof that the merger caused a material group-wide control failure.

The key analytical distinction was between an isolated event and a systemic integration problem. A repeated post-remediation issue, a regulator-detected recurrence, comparable weaknesses at other entities, failure to aggregate group exposure, or a broad remedial programme would be more serious than a local employee or product-control incident. Existing materials do not establish the exact remaining legal-entity timetable, real-time aggregation coverage, unresolved audit findings or capital and liquidity support by subsidiary.

Follow-up deepening. A continued hold was linked to independent confirmation that the breach was contained, client assets and regulatory reporting remained reliable, the subsidiary was independently viable, and remediation had time-bound milestones. The SSC discussion identified a combination that would challenge the isolated-event assumption: a material integration delay of more than six months, parent support above roughly 3% of parent net capital, turnover among senior control personnel, and an extended or broadened regulatory restriction. These are analytical thresholds, not disclosed regulatory standards.

Credit-analysis implication. Parent LCR and consolidated profit should not neutralise a control issue without evidence on financial exposure, client assets, regulatory reporting, remediation effectiveness, business restrictions and the need for parent support. Control and system integration must be monitored at legal-entity level, including offshore and specialist subsidiaries.

3.4 Cross-business asset quality and correlated borrower exposure

Question intent. The fourth question asked whether a longer property, local-government-related and weaker-corporate credit cycle could produce correlated losses in bonds, secured financing, derivatives, leasing, investment banking and offshore businesses. The follow-up tested simultaneous deterioration in stock-pledged financing, leasing and offshore credit while consolidated profit remained positive.

Answer points. The discussion described a broad credit-risk perimeter rather than a confirmed asset-quality crisis. Existing-report and annual-report context includes exposure to bond and other debt instruments, margin and stock-pledged financing, OTC derivatives, finance leasing and sale-and-leaseback receivables. The SSC discussion particularly noted that existing stock-pledged Stage 3 balances and the material leasing/sale-and-leaseback book mean that losses may arise gradually through provisions and recoveries, even without an immediate liquidity shock.

The main unresolved issue is correlation rather than the size of an individual product. Public materials reviewed in the SSC discussion did not provide a consolidated same-obligor and same-sector map across the merged group. A stressed borrower or collateral pool could appear in debt investments, a stock pledge, derivatives, leasing and underwriting-related activity, but the discussion did not assert that such overlap currently exists.

Follow-up deepening. The SSC discussion treated sector-limit reductions, accelerated provisioning, collateral revaluation, subsidiary deleveraging and dividend restraint as potentially supportive actions only if they were paired with evidence of an aggregated exposure map and a reduction of stressed-sector risk. It proposed warning lines including simultaneous Stage 2 or Stage 3 migration in three or more businesses, poor collateral recoveries, and repeated parent support. A parent-support amount above about 3% of net capital was an illustrative escalation point, not a verified threshold.

Credit-analysis implication. Future asset-quality work should distinguish fair-value losses from ECL migration and should not assume that product diversification equals obligor diversification. The essential evidence route is sectoral, top-obligor and cross-business exposure disclosure, together with Stage migration, recoveries, write-offs and subsidiary-capital support.

3.5 Municipal, parent and offshore-entity support assumptions

Question intent. The fifth question examined the dependence of issuer and offshore ratings on expected support from Shanghai municipal government-related shareholders. Its follow-up considered unchanged ownership but non-participation in a needed capital raise, with Guotai Junan International (GTJAI) retaining core status while other offshore entities faced wider spreads or selective support.

Answer points. The discussion maintained the existing-report distinction between expected support and a legal guarantee. Municipal-government-related ownership, strategic importance and current rating context are positive, but do not establish uniform support across Guotai Haitong, GTJAI, former Haitong offshore entities, financing vehicles or individual bonds. The SSC discussion treated GTJAI's reported core status as relevant only to GTJAI and not as proof of support for all group entities.

The exact current support uplift at the parent, current agency classifications of all offshore entities, enforceable guarantees, committed facilities and the timing of cross-border support remain unconfirmed. The discussion therefore did not infer support from ownership alone or from a common brand.

Follow-up deepening. The proposed hold case required stable effective municipal control and strategic-importance language, adequate parent standalone capital, a normal-market capital raise or credible alternative shareholder support, reaffirmed GTJAI core status, and clear legal ring-fencing of weaker non-core entities. The reverse case was a necessary remedial capital raise without proportional or alternative shareholder support, weaker support language, persistent parent-subsidiary spread divergence after structural adjustment, and restructuring or non-support of a material offshore entity. These are analytical conditions to reassess support assumptions, not predictions of an event.

Credit-analysis implication. Each holding requires an entity and instrument-specific analysis of issuer, guarantor, ranking, committed liquidity, regulatory ring-fencing and recovery path. Market spread differences may be useful corroborating evidence only after adjusting for currency, tenor, seniority, liquidity and guarantee status.

5. Monitoring and Next Check

The discussion suggests a compact set of future checks rather than a detailed work programme:

• Monitor parent regulatory ratios together with their drivers: parent net-capital bridge, risk coverage, capital leverage, non-equity securities and derivatives relative to net capital, repo tenor and funding mix.
• Seek legal-entity and currency-level liquidity evidence for GTJAI, former Haitong offshore entities, Haitong Bank, leasing entities and other material subsidiaries before relying on group liquidity fungibility.
• Compare recurring fee income, trading and fair-value income, controllable costs, distributions and risk-asset growth on a rolling basis once a longer post-merger earnings history becomes available.
• Track disclosed remediation, control incidents, restrictions, client-asset and regulatory-reporting issues, subsidiary integration milestones and parent support transactions.
• Build a cross-business borrower and sector view before drawing conclusions about property, local-government-related or weaker-corporate concentration.
• Obtain current primary rating materials and bond documentation before applying support assumptions to a particular offshore obligation.

6. Unverified / Pending Items

The SSC discussion leaves several material points unverified. These include the breakdown of legacy Haitong trading positions; repo haircuts, collateral eligibility and unencumbered collateral by entity; derivative margin sensitivity; offshore liquidity and maturities by currency; quantified synergy targets and parent-only recurring capital generation; remaining subsidiary integration milestones and real-time group-risk aggregation; cross-business same-obligor exposures; and current rating-agency support notching and entity-level group status.

No numerical stress line in this report should be interpreted as a company limit, a regulatory requirement beyond the established minimum ratios, or a published rating-agency trigger. The numbers were used in the SSC discussion solely to make a future evidence threshold explicit. Primary-source disclosure, current rating materials and bond-specific documentation are required before any decision based on those issues.
