1. Business Snapshot and Recent Developments

China Petroleum & Chemical Corporation (“Sinopec Corp.”) is one of China’s largest listed integrated energy and petrochemical companies, with operations in exploration and production, refining, marketing, chemicals and new energy services. For bond investors, the central question is how far the company’s importance in China’s domestic refining, marketing and petrochemical supply, together with control by its parent China Petrochemical Corporation / Sinopec Group, can absorb the margin decline, chemical losses, structural changes in fuel demand, capital-expenditure burden and issue-specific claim risks that became clearer in 2025.

This report distinguishes among Sinopec Corp., Sinopec Group, SINOPE parent-guaranteed bonds, offshore SPVs, and the Chinese government / SASAC. Sinopec Corp. is the core operating company listed in Hong Kong and Shanghai and discloses audited financials, segments, operating metrics and domestic bond information. The main subject of this report is therefore Sinopec Corp.’s own consolidated financial profile. By contrast, Sinopec Group is the central-SOE parent and the credit reference entity for SINOPE parent-guaranteed bonds covered in the existing sinopec_group report. Expectations of parental support should not be equated with a Chinese government guarantee for all Sinopec Corp. debt.

As of end-2025, China Petrochemical Corporation was the de facto controlling shareholder of Sinopec Corp. and held 69.87%, including H shares held through Century Bright. The 2026 first-quarter report also showed that the parent directly held 83,180,556,253 A shares, or 68.79%, while Century Bright held 1,404,842,000 H shares, or 1.16%. The control relationship is clear, but Sinopec Corp. is a listed company with minority shareholders, exchange disclosure obligations, independent consolidated financials and domestic debt. Even when assessing parental support, legal claims, guarantees, fund transfers, dividends and related-party transactions need to be checked separately.

The most recent credit development is the full-year profit decline in 2025 and the partial rebound in 1Q 2026. On a CAS basis, 2025 operating revenue fell 9.5% YoY to RMB2,783.6bn, operating profit fell 44.0% to RMB40.5bn, and net profit attributable to shareholders fell 36.8% to RMB31.8bn. On an IFRS basis, revenue also fell to RMB2,783.6bn, operating profit to RMB48.6bn, and profit attributable to shareholders to RMB32.5bn. The main drivers were lower crude oil prices, lower selling prices and volumes for oil products, weak chemical margins, and impairments on refining and chemical facilities and long-term equity investments.

At the same time, 2025 operating cash flow was RMB162.5bn, higher than RMB149.4bn in 2024. Accounting profit declined sharply, but operating cash flow remained large enough to broadly absorb capital expenditure and exploration spending. However, the strength of operating cash flow does not mean that margin pressure or chemical losses can be dismissed.

In 1Q 2026, profit rebounded YoY. CAS operating revenue was down 3.9% YoY at RMB706.7bn, but profit before tax rose 32.6% to RMB24.2bn and net profit attributable to shareholders rose 28.2% to RMB17.0bn. On an IFRS basis, operating profit rose 23.1% to RMB25.7bn and profit attributable to shareholders rose 26.9% to RMB17.7bn. However, operating cash flow was an outflow of RMB5.6bn, reflecting heavy working-capital pressure from inventories associated with rising crude oil prices and margin payments related to hedging. The quarterly profit rebound should not be treated as conclusive evidence of a full-year improvement.

In one line, Sinopec Corp. is a listed integrated energy and petrochemical company under parent control, combining upstream and natural gas with a downstream and petrochemical core in China. Its credit profile is supported by the domestic refining and marketing network, upstream and natural-gas earnings, operating cash flow, parent control, domestic AAA ratings and policy importance within a central-SOE group. Constraints are chemical losses, medium-term changes in fuel demand, thin margins, capital expenditure, short-term debt, unverified FX and issue-specific terms, and a structure in which parent or government support is easily confused with a legal guarantee.

2. Industry Position and Franchise Strength

Sinopec Corp.’s business platform is deeply embedded in China’s refining, fuel marketing, petrochemical and natural-gas supply chains. This scale increases the difficulty of substitution in domestic supply and supports expectations of parent- and government-related support. At the same time, refining, marketing and chemicals are exposed to prices, demand, regulation, inventories and capital expenditure; even very large revenue scale can still come with thin margins.

The 2025 market environment illustrated both sides clearly. China’s economy maintained 5.0% growth, but according to company statistics, domestic demand for oil products fell 4.1% YoY, with gasoline down 4.5%, diesel down 5.6% and jet fuel up 4.4%. EVs, LNG trucks, fuel-efficiency improvements, changes in industrial activity and shifts in logistics structures are limiting the growth potential of gasoline and diesel demand. The fuel marketing network remains a major competitive advantage, but the model is no longer one that can rely on volume growth.

Demand in the chemicals market itself is increasing. In 2025, consumption increased for ethylene-equivalent demand, PX, synthetic resins, synthetic fibres and synthetic rubber. However, capacity for basic petrochemical products grew faster than demand, and the company stated that overall chemical margins declined. This is why Sinopec Corp.’s chemicals business cannot be treated simply as a growth business. China’s chemical demand is large over the long term, but when overcapacity, price competition, export markets and feedstock prices overlap, scale does not protect earnings.

Refining and marketing are the core businesses supporting Sinopec Corp.’s franchise. In 2025, refinery throughput was about 250 million tonnes and refined oil product output was about 149 million tonnes. In marketing, the company has a presence in China’s domestic oil-product market, a petrol-station network, non-fuel businesses, LNG refuelling, EV charging, battery swapping and hydrogen supply. These are adaptation measures in response to declining oil-product demand. However, low-carbon and new-energy businesses are policy-important, but have not yet reached the scale required to replace the short-term cash flow of the existing refining, marketing and upstream businesses.

Industry risk also requires attention to China’s oil-product pricing system and policy decisions. Sinopec Corp. is affected by domestic fuel prices, export quotas, environmental and safety regulations, decarbonisation policy and SOE reform. The pricing system may soften extreme volatility, but when crude oil prices or inventories move sharply, it can create timing gaps in margins, working capital and inventory valuation.

The strength of the franchise is also clear in peer comparison. PetroChina/CNPC has a stronger upstream and natural-gas profile, while CNOOC is more focused on upstream and offshore resources. Sinopec Corp. has a stronger downstream, marketing and chemicals profile; upstream is an important profit source, but the group’s overall character is more heavily that of China’s refining, marketing and petrochemical supply company. This means that in exchange for domestic supply importance, Sinopec Corp. is also more exposed to EV adoption, changes in fuel demand and chemical overcapacity.

The credit conclusion is that Sinopec Corp.’s industry position is strong. It would be difficult to replace the company quickly in China’s fuel supply and petrochemical supply chain, and domestic market access and parent control also support credit quality. However, the company is not a regulated-tariff utility, but an operating company exposed to market conditions, demand, policy and capital expenditure. Even when assessing support-incorporated credit quality, the quality of segment earnings, especially chemical losses and the decline in marketing profit, is directly relevant to relative valuation and long-dated bond risk.

3. Segment Assessment

Sinopec Corp.’s segments are Exploration and Production, Refining, Marketing and Distribution, Chemicals, and Corporate and Others. For credit analysis, the focus should not be revenue scale but which segments support profit and which segments bring capital consumption and earnings volatility. In 2025, upstream remained the largest source of profit, refining improved, marketing and distribution declined, and chemical losses widened. In 1Q 2026, refining improved sharply, while chemicals remained loss-making.

Note: Units are RMB bn. 2024-2025 figures use segment operating profit from the annual report, while 1Q 2026 uses EBIT from the quarterly report. Quarterly EBIT is affected by seasonality, inventories and accounting presentation, and should not be directly compared with full-year segment operating profit.

Exploration and Production underpins Sinopec Corp.’s profit. In 2025, oil and gas production increased 1.9% YoY to 525.28 million boe, crude oil production was 282.40 million barrels, and natural-gas production increased 4.0% to 1,456.6 bcf. Segment profit declined from 2024 because of lower oil prices, but the segment still generated RMB45.5bn of operating profit. In natural gas, the company emphasises coordination across production, supply, storage and marketing, and profitability in the natural-gas chain provides support. From a credit perspective, the upstream business makes the company more resilient than a pure downstream or chemicals company, but because Sinopec Corp. is not as upstream-oriented as PetroChina or CNOOC, it cannot fully offset weakness in downstream and chemicals.

Refining combines very large scale with thin margins. In 2025, refinery throughput was about 250 million tonnes and refined oil product output was about 149 million tonnes, giving the company a central role in domestic fuel supply. Refining segment operating profit improved to RMB9.4bn in 2025, but the margin was low relative to the size of revenue and throughput. In 1Q 2026, EBIT improved sharply to RMB18.9bn, driven by higher Brent prices, inventory gains and improved refining by-product margins. However, this was heavily influenced by market conditions, inventories and margins, and does not indicate a structural shift to high profitability. Refining is a business platform supporting credit quality, but under stress it can also affect cash flow through inventories and working capital.

Marketing and Distribution is the clearest expression of Sinopec Corp.’s franchise. Domestic refined-product marketing, the petrol-station network, Easy Joy, LNG refuelling, EV charging and battery swapping, and hydrogen supply are sales channels connected to consumer and industrial demand. In 2025, domestic oil-product demand declined, and Marketing and Distribution segment operating profit fell to RMB10.0bn. In 1Q 2026, domestic sales volume was 43.42 million tonnes, up 0.6%, and retail sales were up 1.2%, but domestic oil-product consumption still fell 2.3% YoY because of the impact of alternative energy. The marketing network is a competitive advantage, but it is difficult to assume that sales volumes and margins will keep growing over the long term.

Chemicals are currently the largest business constraint. In 2025, external sales of chemical products fell 9.6% YoY to RMB378.0bn, mainly because of lower product prices. The segment operating loss widened from RMB10.0bn in 2024 to RMB14.6bn in 2025, and EBIT remained negative at RMB5.8bn in 1Q 2026. The company is advancing high-value-added products, low-cost technologies, high-performance materials, POE, carbon materials and product-mix improvement, but as long as overcapacity in basic chemicals persists in China, earnings improvement in chemicals is likely to take time. From a credit perspective, chemicals should be recognised as a policy-relevant and growth-related investment area, but in the short to medium term it should also be treated as a constraint on earnings and capital expenditure.

At the segment level, Sinopec Corp. is an issuer that supports profit through upstream and natural gas, maintains its franchise through the scale of refining and marketing, and carries chemical losses and energy-transition investment. For default risk, parent control, domestic market access and the scale of operating cash flow are important. For relative valuation within the same rating category or among Chinese SOEs, chemical losses, the decline in marketing profit, structural changes in oil-product demand and refining-margin volatility need to be explicitly discounted.

4. Financial Profile and Analysis

Sinopec Corp.’s financial profile combines enormous revenue scale, thin margins, still-large operating cash flow, heavy investment spending and a short-term debt structure that cannot be called fully conservative. In 2025, revenue and profit fell sharply, but operating cash flow improved. Credit analysis needs to examine not only earnings but also how much headroom operating cash flow provides against capital expenditure, exploration spending, dividends and short-term debt.

The table below summarises key financial indicators mainly on a CAS basis, together with supplementary IFRS metrics. Sinopec Corp. discloses under both IFRS and CAS, and presentation differs by accounting standard, including for operating profit. For international comparison, IFRS is relevant; for domestic bonds and the company’s key metrics, it is practical to also refer to CAS.

Note: Units are RMB bn unless otherwise stated. 2023-2025 figures are mainly from the 2025 annual report; 1Q 2026 figures are from the 2026 first-quarter report. The table explicitly identifies accounting standards because CAS and IFRS figures are mixed. Company-disclosed capital expenditure and capital expenditure plus exploration well expenditure in the cash-flow statement have different definitions.

The 2025 profit decline was large. Operating revenue fell 9.5% YoY, CAS operating profit fell 44.0%, and CAS net profit attributable to shareholders fell 36.8%. The company cited lower crude oil prices, lower product selling prices and volumes, weaker chemical margins, impairments and higher finance costs. Finance costs were RMB14.7bn, up 31.1% YoY, reflecting an increase in interest-bearing debt and FX losses on part of the foreign-currency borrowings. This may differ in presentation scope from the interest-expense-related figure referenced in the liquidity table, so the two should not be treated as the same concept. From a credit perspective, it is important that in a period of lower operating profit, finance costs and FX can put additional pressure on net profit.

Operating cash flow increased in the same year. In 2025, operating cash flow was RMB162.5bn, above RMB149.4bn in 2024. This shows that lower accounting profit does not immediately imply a sharp decline in repayment capacity. Investment spending in the cash-flow statement, combining capital expenditure and exploration well expenditure, was RMB133.6bn, leaving a gap of about RMB28.9bn versus operating cash flow. After considering dividends, interest payments, leases, investments, working capital and debt repayment, headroom is not substantial, but the absolute amount of operating cash flow is large.

Capital expenditure is an important credit constraint. Company-disclosed annual capital expenditure for 2025 was RMB147.2bn, comprising RMB70.9bn for Exploration and Production, RMB22.0bn for Refining, RMB13.8bn for Marketing and Distribution, RMB35.9bn for Chemicals and RMB4.6bn for Others. Investment is directed toward upstream production maintenance, natural gas, refining upgrading, integrated energy stations, major chemical projects, R&D and digitalisation. From a credit perspective, much of this investment is required for business maintenance and policy adaptation, and therefore cannot easily be treated as discretionary spending that can be cut in a downturn.

1Q 2026 was positive on earnings but requires caution on cash flow. IFRS operating profit improved to RMB25.7bn and profit attributable to shareholders to RMB17.7bn, but operating cash flow was an outflow of RMB5.6bn. The company attributed this to working capital, including inventories related to higher international crude oil prices, and margin payments for hedging business. This shows that profit improvement in a single quarter can be accompanied by higher inventories and cash outflow. For oil companies, profit, inventories, working capital, hedging and crude oil prices do not always move in the same direction.

The overall financial assessment is that Sinopec Corp. is strong as a support-incorporated issuer, but as a standalone operating company, thin margins and the investment burden must always be monitored. The 2025 profit decline alone does not require a major downgrade of credit quality because the company has operating cash flow, asset scale, parent control and access to domestic capital markets. However, margins, finance costs, short-term debt, chemical losses and capital expenditure are the reasons why Sinopec Corp.’s credit quality should not be equated with that of the sovereign or policy banks.

5. Structural Considerations for Bondholders

For Sinopec Corp. bondholders, the most important point is not to confuse the legal entity against which they have a claim. Sinopec Corp. is a listed company with its own domestic bonds, bank borrowings, leases and intra-group borrowings. Sinopec Group, as the parent, can be the credit reference entity for SINOPE-related offshore guaranteed bonds or exchangeable bonds. Market tickers and common usage often group these together as “Sinopec,” but the legal entities are not the same.

The domestic bond information in the 2025 annual report shows that Sinopec Corp. has issued medium-term notes and technology-innovation bonds in the National Interbank Bond Market, with multiple outstanding domestic bonds including 2025 and 2026 issuance. The annual report shows a domestic issuer rating of AAA and a 20-year bond rating of AAA, and states that these bonds are unsecured. This indicates strong credit recognition in the domestic market, while repayment of specific bonds still depends on Sinopec Corp.’s own credit profile and market access.

Parental support is strong, but it is separate from a legal guarantee. Sinopec Corp. is Sinopec Group’s core listed subsidiary, and the parent is the de facto controlling shareholder. If Sinopec Corp. were to become materially unstable, this would have broad implications for the parent group’s fuel and petrochemical supply, listed platform, domestic and overseas market access, and policy role. Parent support expectations are therefore stronger than for a normal private petrochemical company. However, the parent does not necessarily explicitly guarantee all Sinopec Corp. debt, and neither the Chinese government nor SASAC directly guarantees the debt.

Sinopec Corp.’s listed-company structure provides transparency for bond investors, but it is also a structure in which cash diversion or automatic transfer to the parent cannot be taken for granted. Audited financials, segment information, major subsidiaries, related-party transactions and shareholding structure support the credit profile, but minority shareholders, regulation, disclosure requirements and shareholder interests also matter. Sinopec Corp.’s cash is not automatically freely available for all Sinopec Group parent bonds.

For specific bond investments, domestic bonds must be separated from foreign-currency bonds and parent-guaranteed bonds. For domestic bonds, investors should examine the issuer, domestic rating, security or guarantee, early redemption, investor-protection clauses, use of proceeds, maturity and liquidity. For foreign-currency bonds or SINOPE-related bonds, investors should confirm the SPV, parent guarantee, governing law, NDRC/SAFE status, negative pledge, cross default, change of control, tax terms and exchange terms. This issuer summary has not reviewed individual offering circulars.

The structural conclusion is that Sinopec Corp. should not be treated as “government-guaranteed” or as fully identical to Sinopec Group. It is reasonable to give weight to parent and government-related support as a credit strength, but individual bonds should not be collapsed into a single risk bucket without checking the recovery source, guarantee, ranking, change of control, FX remittance and issuer.

6. Capital Structure, Liquidity and Funding

Sinopec Corp.’s liquidity is supported by the scale of operating cash flow, domestic market access, cash balances and relationships with the parent group. However, short-term debt and maturities within one year are large, and the company also has capital expenditure and dividends, so it is not an issuer with pure surplus cash. Liquidity assessment should consider not only cash balances but also operating cash flow, inventories and working capital, access to domestic banks and bond markets, and the refinancing capacity for short-term borrowings.

Note: Units are RMB bn. The table reorganises line items from the 2025 annual report for credit analysis purposes and is not a fully reconstructed debt maturity ladder. Short-term debt refers to the company-disclosed short-term debts, short-term borrowings referred to in the text are a separate line item, non-current liabilities due within one year are a separate item, and corporate bonds / bond-like liabilities represent bond-like liabilities outstanding. Classification and overlap with long-term debt require reconstruction from individual notes.

At end-2025, Sinopec Corp. had a net current liability structure, with current liabilities exceeding current assets. IFRS disclosures showed non-current assets of RMB1,630.7bn, net current liabilities of RMB175.8bn and non-current liabilities of RMB468.1bn at end-2025. For a large oil, refining and marketing company, net current liabilities do not necessarily indicate an immediate liquidity crisis, because inventories, receivables, payables, short-term borrowings and commodity-price changes all affect the balance sheet. However, bond investors should clearly recognise that continuous access to bank borrowings and domestic bond markets is an assumption.

In 2025, short-term borrowings declined, while non-current liabilities due within one year and corporate bond balances increased. The annual report shows that short-term borrowings fell to RMB29.5bn, while reclassification of non-current liabilities due within one year increased to RMB110.6bn, and corporate bond balances increased to RMB52.3bn. Short-term borrowings here are one component of short-term debt and differ in scope from total short-term debt in the table. From a credit perspective, not only repayment of short-term bank borrowings but also market funding and maturity management, including long-term bonds, MTNs and technology-innovation bonds, have become important.

The relationship between operating cash flow and investment spending supports normal-course funding, but headroom is not thick. In 2025, operating cash flow was RMB162.5bn, and capital expenditure plus exploration well expenditure in the cash-flow statement was RMB133.6bn. The difference was only RMB28.9bn, and dividends, buybacks, interest payments, additional investments, working-capital movements and debt repayments still need to be considered. The company proposed an annual dividend of RMB0.2 per share for 2025 and maintained a high profit-distribution ratio including buybacks. Shareholder returns are important for a listed company, but in credit analysis, the question is whether dividends and buybacks constrain debt-reduction capacity during a profit downturn.

Parent and intra-group financing are also important. At end-2025, the company had borrowings from the group and fellow group companies in both current and non-current liabilities. Group finance functions such as Sinopec Finance Co. may improve funding efficiency under normal conditions. At the same time, intra-group funding depends on relationships with the parent and affiliates, regulation and contract terms. External bondholders need to check the ranking, collateral, contractual terms and priority of fund transfers for intra-group borrowings on an issue-specific basis.

There are still unverified liquidity items. Unused committed lines, bank facilities, foreign-currency cash and debt, hedging, the maturity ladder, restricted cash and early-redemption clauses for individual bonds have not been fully extracted. For an investment decision in a specific bond, maturity, currency, guarantee and bank facilities need additional confirmation.

7. Rating Agency View

When reading Sinopec Corp.’s ratings, domestic ratings, international ratings, parent Sinopec Group ratings and government-related issuer assessments need to be separated. The 2025 annual report shows an issuer rating of AAA and a 20-year bond rating of AAA for domestic bonds. This indicates high credit recognition and funding access in China’s domestic market. However, a domestic AAA rating is not the same as an international A-range rating; it is a relative assessment on a domestic credit scale.

For international ratings, the latest Fitch/Moody’s issuer-specific detailed reports were not obtained at the time of this report. The Fitch Dodd-Frank disclosure that was obtained stated that in the 12 November 2024 action, China Petroleum & Chemical Corporation had a Long-Term IDR of A+, a Negative Outlook and a Short-Term IDR of F1+. This indicates that at least at that time, Sinopec Corp. was treated as a high-investment-grade, support-incorporated credit internationally, but Fitch’s latest detailed view after its 2025 change to China’s sovereign rating has not been confirmed.

For S&P, Sinopec Group-related guaranteed exchangeable bond materials confirm a China Petrochemical Corporation / Sinopec Group reference of A+/Stable/A-1 and a very high likelihood of government support. This is important for understanding the parent-support background, but should not be cited directly as the rating rationale for all Sinopec Corp. debt. Parent credit, parent-guaranteed bonds and the listed subsidiary’s domestic bonds are close but not identical.

The central point from rating-agency views is that the credit quality of the group is supported not only by standalone operations but also strongly by parent and government-related factors. Sinopec Corp. itself is also an important listed core company in China’s energy and petrochemical supply, with parent control and domestic market access. However, support incorporated in ratings should not be confused with high standalone profitability or an explicit guarantee from the Chinese government.

Rating monitoring items include China’s sovereign rating, central-SOE support assessment, Sinopec Group’s ratings and outlook, Sinopec Corp.’s profit, operating cash flow and debt, chemical losses, refining and marketing profit, domestic bond ratings, and the latest actions by Fitch, Moody’s and S&P. In particular, for support-incorporated ratings, changes in the sovereign or government-support assessment can affect ratings more than standalone financials. At the same time, if lower standalone margins or higher debt persist, they can affect relative valuation and spreads even with parent and government support.

8. Credit Positioning

Sinopec Corp.’s relative positioning is best framed among parent Sinopec Group, PetroChina/CNPC, CNOOC, policy banks, the Chinese sovereign, other central-SOE chemical companies and private petrochemical companies. Sinopec Corp. has government-support expectations and listed-company transparency, but it also has a strong downstream and chemicals profile and thin margins. It should therefore be evaluated not as a substitute for policy banks or the Chinese sovereign, but as a large support-incorporated central-SOE operating company.

Among China’s national oil companies, Sinopec Corp. has a higher downstream and petrochemical weighting. This increases its policy importance in domestic fuel supply and marketing networks, but also increases sensitivity to EV adoption, diesel demand, refining margins and chemical overcapacity. Compared with companies with a higher upstream share, earnings elasticity in an oil-price upcycle may be more limited, but the difficulty of replacing the marketing network and refining assets is high. Which profile is better depends on the combination of oil prices, domestic demand, chemical market conditions, government-support assessment and bond pricing.

Sinopec Corp. is relatively strong in disclosure transparency. As an HKEX/SSE-listed company, it provides annual reports, quarterly reports, segment earnings, domestic bond information, major subsidiaries and parent ownership percentages. This supports credit analysis by enabling investors to verify business and financial performance, especially compared with situations where the latest standalone balance sheet and cash-flow statement for parent Sinopec Group are not sufficiently available. However, listed-company transparency is not a substitute for a legal guarantee or government guarantee.

This report does not make a rich/cheap or buy/sell conclusion on market relative value because live spreads, OAS, CDS and same-maturity bond comparisons have not been checked. Investment decisions should assess whether the spread differentials versus China sovereigns, policy banks, CNPC/PetroChina, CNOOC, Sinopec Group guaranteed bonds and ChemChina/Sinochem-related bonds sufficiently compensate for Sinopec Corp.’s downstream and chemical risk, legal-entity differences, short-term debt and chemical losses.

9. Key Credit Strengths and Constraints

Sinopec Corp.’s greatest strength is the difficulty of substituting its role in China’s refining, fuel marketing and petrochemical supply. Refinery throughput, the fuel marketing network, chemical product supply, natural gas and upstream production, and integrated energy stations are widely connected to the domestic economy and industrial supply chain. This role is linked to control by parent Sinopec Group, domestic funding access, domestic AAA ratings and policy importance, supporting normal-course refinancing capacity.

The second strength is the scale of operating cash flow. Profit declined sharply in 2025, but operating cash flow remained high at RMB162.5bn. This indicates that despite the effects of inventories, depreciation, working capital and taxes, the company continues to have substantial cash-generation capacity. The fact that operating cash flow can broadly absorb capital expenditure and exploration spending supports standalone operating credit quality.

The third strength is upstream and natural-gas profit and the marketing network. Exploration and Production remained the largest profit source in 2025, and natural-gas production increased. Marketing and Distribution profit declined in 2025, but the business remains the company’s customer interface in the domestic market and the platform for conversion to new energy. This business diversification supports credit quality compared with a pure chemical company.

The first constraint is thin margins and the 2025 profit decline. CAS operating profit was RMB40.5bn, and the operating margin fell to the mid-1% range. Even on an IFRS operating-profit basis, the operating margin was below 2%. Because margins are thin relative to the enormous revenue scale, changes in prices, inventories, crude oil, chemical margins and finance costs can move net profit significantly.

The second constraint is chemical losses. The Chemicals segment loss widened to RMB14.6bn in 2025 and remained negative in 1Q 2026. China’s chemical demand is increasing, but if basic petrochemical capacity growth exceeds demand growth, larger-scale businesses are exposed to price competition and impairments. Transitioning to higher-value-added materials is necessary, but does not guarantee improvement in short-term credit metrics.

The third constraint is capital expenditure and short-term debt. Investment in upstream, refining, chemicals, new energy and the marketing network is needed for business maintenance and policy adaptation. 2025 capital expenditure was RMB147.2bn, large relative to operating cash flow. Short-term debt and liabilities due within one year are also large, and domestic market access is an assumption. Sudden funding stress is unlikely because of parent-support expectations, but refinancing dependence remains.

The fourth constraint is structural confusion risk. Sinopec Corp. is Sinopec Group’s core listed subsidiary, but it is not the parent itself. If Sinopec Corp. domestic bonds, Sinopec Group guaranteed bonds, offshore SPV bonds, exchangeable bonds and government-support expectations are treated as one, bondholder claims can be misunderstood. Legal guarantees, maturity structure, bank facilities, the latest international rating rationale and the persistence of chemical losses remain provisional items in this report.

10. Downside Scenarios and Monitoring Triggers

The most realistic downside path is a simultaneous slowdown in oil-product demand, deterioration in chemical margins, decline in refining margins and continuation of capital expenditure. In this case, despite the large revenue base, the operating margin would become even thinner and the headroom after deducting capital expenditure, exploration spending, dividends and interest from operating cash flow would shrink. If operating cash flow is maintained, as in 2025, the company has resilience; if working capital deteriorates and operating cash flow also falls, dependence on short-term borrowing and domestic bond refinancing would increase.

The second downside is the persistence of chemical losses and the fuel-demand transition. If overcapacity, demand slowdown, lower export prices, feedstock prices, EV adoption and fuel-efficiency improvements overlap, chemical losses, lower marketing profit and delayed investment recovery could occur at the same time. Expansion into high-value-added materials, LNG, EV charging, hydrogen and non-fuel services is necessary, but it will not fully replace existing fuel-marketing profit in the short term.

The third downside is a change in support expectations or sovereign / central-SOE assessment. Sinopec Corp. is often viewed as a support-incorporated issuer, and parent control and policy importance are significant. However, if China’s sovereign rating, central-SOE support assessment or the credit outlook for parent Sinopec Group deteriorates, ratings and spreads could react even without a sharp change in standalone financials. Conversely, even if government-support expectations are strong, legal recovery analysis is still required separately where a specific bond has no explicit guarantee.

Monitoring should prioritise the 2026 interim results, 2026 full-year outlook, whether chemical segment losses narrow, Marketing and Distribution profit, the gap between operating cash flow and capital expenditure, short-term debt and maturities within one year, domestic bond issuance, parent-support assessment, the latest actions by Fitch/Moody’s/S&P, and China’s sovereign rating. In particular, it is necessary to confirm whether the 1Q 2026 profit improvement is limited to temporary factors such as inventory gains and refining margins, or whether it connects to full-year operating cash-flow improvement.

11. Credit View and Monitoring Focus

Based on the confirmed public information, Sinopec Corp.’s current credit quality appears to have upper-investment-grade resilience on a support-incorporated basis as a listed core energy and petrochemical company under a Chinese central-SOE group. However, the latest Fitch/Moody’s issuer-specific detailed reports have not been obtained, and the details of rating triggers and support incorporation remain provisional. This credit level is not a direct guarantee from the Chinese government. It is supported by de facto control by Sinopec Group, the company’s importance in domestic refining, marketing and petrochemical supply, domestic capital-market access and the scale of operating cash flow. The near-term credit direction is stable to somewhat cautious. The 1Q 2026 profit rebound is positive, but a sustained improvement sufficient to offset the sharp profit decline in 2025, chemical losses and lower marketing profit has not yet been confirmed.

This credit view is supported by Sinopec Corp.’s domestic supply importance and operating cash flow. Even though profit fell in 2025, operating cash flow remained at RMB162.5bn. Upstream and natural gas are the largest profit source, while refining and the marketing network support domestic supply and customer access. Disclosure as a listed company is also substantial, and the domestic AAA rating and access to the interbank bond market support normal-course funding. De facto control by Sinopec Group also provides credit support that a standalone private petrochemical company would not have.

At the same time, standalone business risk cannot be ignored. The 2025 profit decline was large, and chemical segment losses widened. Marketing and Distribution profit also fell, and domestic oil-product demand declined. Chemical overcapacity, EV adoption, refining margins, crude oil prices, inventories, working capital and capital expenditure will continue to move Sinopec Corp.’s credit metrics. Strong parent and government linkage supports a floor for default risk, but these business constraints should be reflected in relative valuation within the same rating category and in the pricing of long-dated bonds.

For bond investors, the most important point is not to equate Sinopec Corp. mechanically with parent Sinopec Group or the Chinese government itself. Sinopec Corp. domestic bonds are claims on the company itself, and some domestic bonds confirmed in the annual report are stated to be unsecured. Sinopec Group guaranteed bonds and exchangeable bonds have different legal structures, and risks should not be aggregated solely because the market uses the SINOPE name. For individual bonds, investors need to confirm the issuer, guarantor, ranking, NDRC/SAFE status, governing law, negative pledge, cross default, change of control and tax terms.

In terms of portfolio direction, Sinopec Corp. is a defensive large-scale Chinese central-SOE energy and petrochemical credit, but it is not a substitute for policy banks or the sovereign. Compared with PetroChina/CNPC or CNOOC, its greater downstream and chemical exposure means that chemical losses and the fuel-demand transition require closer monitoring. Because live spreads are unavailable, this report does not make a rich/cheap conclusion. Investment decisions should separately assess whether the spread differential versus same-maturity China sovereigns, policy banks, PetroChina/CNPC, CNOOC, Sinopec Group guaranteed bonds and ChemChina/Sinochem-related bonds sufficiently compensates for Sinopec Corp.’s business and structural risks.

Future monitoring should focus first on whether the 1Q profit rebound continues into operating cash flow and segment profit in the 2026 interim results. Next, chemical losses, Marketing and Distribution profit, domestic oil-product demand, refining margins, capital expenditure, short-term debt, domestic bond issuance, finance costs, parent-support assessment and the latest actions by international rating agencies should be checked. Sinopec Corp.’s credit quality will be determined less by short-term profit rebounds than by whether the company can maintain operating cash flow and refinancing capacity while absorbing chemical losses and the fuel-demand transition.

12. Short Summary & Conclusion

Sinopec Corp. is a listed integrated energy and petrochemical company under Sinopec Group, centred on China’s refining, oil-product marketing and petrochemical businesses, with upstream, natural gas and new energy as well. Its credit quality is supported by domestic supply importance, parent control, domestic AAA ratings and large operating cash flow, while the 2025 profit decline, chemical losses, medium-term changes in fuel demand, short-term debt and differences in legal entities across individual bonds need to be analysed separately. Support expectations from the Chinese government and the parent are important credit anchors, but Sinopec Corp. bonds should not be equated with directly government-guaranteed bonds or Sinopec Group guaranteed bonds. Issuer, guarantee, maturity and terms need to be checked bond by bond.

14. Unverified / Pending

1. Latest full Fitch and Moody's issuer-specific reports for Sinopec Corp. were not obtained. International rating triggers, support assumptions and post-2025 sovereign-related changes should be checked before a rating-focused update; this mainly affects the support-incorporated rating view and peer-rating comparison, not the basic company financial summary.
2. Specific domestic and offshore offering circulars were not reviewed issue by issue. Before investing in a specific bond, confirm issuer, guarantor, guarantee scope, ranking, negative pledge, cross default, change of control, tax gross-up, governing law, NDRC/SAFE status, put/call terms, exchangeability and outstanding amount; this affects recovery, covenant and issue-specific risk, not the broad issuer franchise assessment.
3. Detailed debt maturity ladder, unused committed bank lines, restricted cash, foreign-currency debt, foreign-currency cash and hedge position were not fully extracted in this workflow. This limits the precision of liquidity runway and refinancing-risk analysis.
4. Sinopec Corp. 2026 Q1 is unaudited and may be affected by inventory, hedging margin and other working-capital movements. Confirm 2026 interim results before treating the Q1 profit rebound as a sustained trend; this affects the direction-of-travel view for 2026 rather than the audited 2025 baseline.
5. Live bond prices, spreads, OAS, CDS and same-maturity peer comparisons were not available in this workspace. No relative-value conclusion is made; this limits buy/sell or rich/cheap conclusions, not the issuer-level credit diagnosis.
