1. Business Snapshot and Recent Developments

China Petrochemical Corporation (“Sinopec Group”) is a central government-owned integrated energy and petrochemical group in China. It should be viewed as an integrated issuer spanning the upstream-to-downstream chain, with operations in oil and gas exploration and development, storage and transportation, refining, petroleum product sales, petrochemicals and chemicals, engineering, equipment, financial services, and new energy. For bond investors looking at SINOPE debt, the first question is how far the company’s importance to China’s energy security and the expectation of government support can absorb the refining and chemical cycles, structural changes in domestic fuel demand, capex burden, and guarantee and covenant risks at the individual-bond level.

This report clearly separates Sinopec Group, its listed core subsidiary China Petroleum & Chemical Corporation (“Sinopec Corp.”), offshore issuing SPVs, and the Chinese government / SASAC. Sinopec Corp. is the Hong Kong- and Shanghai-listed core operating company and has the most extensive public financial disclosure. It is therefore the most important public proxy for assessing the group’s earnings power and cash generation. At the same time, Sinopec Corp.’s cash, debt, and operating cash flow should not be treated as identical to the liquidity of the Sinopec Group parent or as the repayment source for all SINOPE bonds.

Sinopec Group’s 2024 annual report positions the company as China’s largest supplier of petroleum and petrochemical products, the world’s largest refining company, and the world’s second-largest chemical company. It also states that the company has the world’s second-largest number of service stations. This scale is not merely a corporate description; it is a credit support factor. Because domestic fuel supply, petrochemical feedstock supply, natural gas, engineering, and the product sales network are broadly integrated, any instability in the company’s financing or operations would have wide implications for China’s energy and industrial supply chains. This policy importance underpins the government support incorporated by rating agencies.

However, performance from 2024 to early 2026 shows that Sinopec is not an issuer that can be ignored simply because it is a strong government-related entity. It needs to be assessed by separating support-inclusive credit strength from standalone business risk. Sinopec Group’s 2024 operating income was RMB3,138.8bn, operating profit was RMB103.2bn, and net profit was RMB82.5bn, representing declines in both revenue and profit from 2023. At the listed core subsidiary Sinopec Corp., 2025 IFRS revenue was RMB2,783.6bn, operating profit was RMB48.6bn, and profit attributable to shareholders was RMB32.5bn, all of which clearly declined from 2024. In 1Q 2026, although unaudited CAS profit attributable to shareholders recovered by 28.2% year on year to RMB17.0bn, operating cash flow was negative, so structural improvement should not be inferred from one quarter alone.

In 2025, Sinopec Group issued HKD7.75bn of 0.75% exchangeable bonds through Deep Development 2025 Ltd., with Sinopec Group providing an unconditional and irrevocable guarantee. S&P assigned the bonds an A+ rating, the same as Sinopec Group’s long-term issuer credit rating, and views the likelihood of government support for the company as extremely high. However, the exchangeable bonds are not direct obligations guaranteed by the Chinese government. They are securities with exchangeability into Sinopec Corp. shares, a parent guarantee, an offshore issuer, and specific terms. Bonds should not be grouped into a single risk category solely because they carry the SINOPE ticker; the guarantor, ranking, exchangeability, maturity, currency, and governing law need to be checked individually.

In one sentence, Sinopec Group is a central SOE integrated energy group centred on China’s downstream and petrochemical sectors, while also encompassing upstream, natural gas, a sales network, engineering, and new energy. Its credit quality is supported by SASAC control, policy importance, its domestic refining, marketing, and chemical scale, Sinopec Corp.’s cash generation, and capital market access. Constraints, however, include refining and chemical market volatility, medium-term structural changes in domestic petroleum product demand, chemical segment losses, limited detailed disclosure of parent-company financials, and unverified terms of individual bonds.

2. Industry Position and Franchise Strength

Sinopec Group’s business base is characterised by the overlap between competitive strength and policy indispensability. As an oil and petrochemical company, its competitive advantages stem from oil and gas resources, refining capacity, chemicals production, sales networks, logistics and storage, brand, customer base, research and development, and funding capacity. At the same time, the company is a Chinese central SOE and not merely a private energy company. Because it is responsible for domestic fuel supply, petrochemical feedstocks, natural gas, and energy services for transport and industry, the government has strong incentives to maintain the company’s operations and credit standing.

Sinopec’s strength is particularly evident downstream. China is one of the world’s largest demand markets for petroleum products and chemicals, and Sinopec sits at the centre of that domestic supply network. In 2024, Sinopec Group reported crude throughput of 252 million tonnes, refined oil product output of 153 million tonnes, domestic refined oil product sales of 182 million tonnes, of which retail sales were 110 million tonnes. On a Sinopec Corp. basis, 2024 oil and gas production was 515.35 million boe, crude throughput was 252 million tonnes, refined oil product output was 153 million tonnes, petroleum product sales were 239 million tonnes, and chemical sales volume was 83.45 million tonnes. The definitions are not fully identical between Group and Corp., but it is clear that the company is a leading player in China’s refining, marketing, and chemicals sectors.

The downstream bias is both a strength and a constraint. The refining and marketing network is broadly linked to domestic demand, pricing policy, inventory management, imported crude procurement, refining margins, logistics, and fuel-quality regulations. As long as vehicle ownership, logistics, aviation demand, and industrial activity in China remain resilient, Sinopec’s sales network provides a large earnings base. At the same time, EV adoption, fuel-efficiency improvements, changes in urban transport structures, and slower economic growth will constrain medium-term growth potential for gasoline and diesel demand. This does not immediately raise Sinopec’s default risk, but it constrains profit growth in the marketing and refining businesses and raises the difficulty of capital allocation, including capex and shareholder returns.

In chemicals, Sinopec has major scale, but from a credit perspective, strength and weakness coexist. Petrochemicals, synthetic resins, synthetic fibres, high-value-added materials, and related products are important areas tied to China’s industrial upgrading and import substitution. Sinopec Group’s 2024 annual report states that the chemicals business worked to raise the share of high-value-added products, adjust utilisation of low-margin facilities, reduce logistics costs, customise products, and expand into advanced materials. However, Sinopec Corp.’s chemicals segment recorded an operating loss of RMB10.0bn in 2024 and an operating loss of RMB14.6bn in 2025. When China’s domestic petrochemical overcapacity, product price declines, naphtha and crude oil prices, export competition, and slower demand overlap, scale does not guarantee earnings stability.

Upstream and natural gas partly offset volatility in downstream and chemicals. In 2024, Sinopec Corp.’s exploration and production segment recorded operating profit of RMB56.4bn and was the core profit contributor. Sinopec Group’s 2024 annual report also states that natural gas sales volume was approximately 68.4bcm, up 9% year on year, with profit up 33%. Natural gas is highly important from the policy perspectives of China’s energy transition, city gas, industrial fuel, power generation, and winter supply. However, upstream is affected by oil and gas prices, reserves, development costs, geological risk, and overseas political risk. Compared with PetroChina/CNPC, Sinopec has historically had a stronger downstream profile, and upstream earnings alone cannot stabilise the entire group.

New energy and low-carbon businesses should be viewed as medium- to long-term business adaptability rather than near-term repayment sources. Sinopec Group’s 2024 annual report reports cumulative installed wind and solar capacity of 2,126MW, annual green power of 1bn kWh, 10,285 charging and battery swap stations, approximately 100,000 charging points, 5,490 service stations equipped with solar power, and 142 hydrogen stations. These are attempts to repurpose the existing sales network for a new-energy era and mitigate the risk of continued reliance on petroleum product sales alone. However, their scale is not yet sufficient to replace the group’s overall earnings and cash flow, and payback, policy subsidies, utilisation rates, and the competitive environment need to be monitored.

The credit conclusion is that Sinopec Group’s industry position is very strong. It is difficult to substitute the company within China’s energy and petrochemical supply chain. At the same time, the company is not a regulated-tariff utility; it is an operating company exposed to crude oil, product prices, chemical spreads, demand, policy, and capex. The support expectation as a government-related issuer strongly supports the downside of credit quality, but business earnings volatility, especially chemical losses and softer marketing and refining margins, cannot be ignored in spread and relative-value analysis.

3. Segment Assessment

Viewed by segment, Sinopec clearly separates into pillars that support issuer credit quality and areas that bring earnings volatility. This report could not obtain sufficient latest segment profit data for the Sinopec Group parent itself, so the analysis here focuses on Sinopec Corp.’s 2024 and 2025 segment profit, supplemented by business discussion in the Group annual report. Sinopec Corp. is not the entire Group, but as the listed core subsidiary, it best indicates the direction of business risk.

Exploration and production was the core profit contributor in both 2024 and 2025. When oil prices remain at a certain level and natural gas sales grow, upstream can partly offset profit pressure in downstream and chemicals. In 2024, Sinopec Corp.’s exploration and production segment increased profit by 25.4% year on year, compensating for weakness in refining, marketing, and chemicals. In 2025, operating profit declined to RMB45.5bn, but it remained the largest profit source within the group and shows that the company is not a pure downstream company.

Refining has large scale but thin margins. Sinopec Corp.’s refining segment operating profit improved to RMB9.4bn in 2025, but profitability is low relative to revenue scale. In refining, crude procurement prices, product prices, inventory valuation, the domestic pricing mechanism, product mix, utilisation rates, and environmental regulations all matter at the same time. Sinopec Group states that in 2024 it advanced crude throughput allocation by region, coordination between refining and marketing, and production optimisation for chemical feedstocks. These are important profit-improvement measures, but they do not mean that refining margins have structurally become thick.

Marketing and distribution is Sinopec’s most visible franchise. Its nationwide service station network, non-fuel services including Easy Joy, and industrial, commercial, and retail sales channels form barriers to entry against competitors. Sinopec Group’s 2024 annual report reported domestic refined oil product sales of 182 million tonnes, of which retail sales were 110 million tonnes. However, Sinopec Corp.’s marketing and distribution segment profit fell sharply to RMB10.0bn in 2025 from RMB18.6bn in 2024. This shows that scale in the sales network alone does not protect margins. Changes in domestic fuel demand, price competition, the profitability of non-fuel businesses, and substitution by EV charging need continuous monitoring.

Chemicals is the largest business constraint from a credit perspective. Sinopec is described as the world’s second-largest chemical company, with large scale in synthetic resins, synthetic fibres, basic chemicals, fine chemicals, and new materials. However, Sinopec Corp.’s chemicals segment was loss-making in both 2024 and 2025, with losses widening in 2025. China’s petrochemical overcapacity, slower domestic demand, competition in export markets, feedstock prices, utilisation rates, and environmental regulations can easily overlap. The Group is pursuing high-value-added products, advanced materials, cost reductions, and utilisation adjustments for low-margin facilities, but in credit analysis the chemicals business should not be treated simply as a growth area. It should be treated as a constraint that consumes capital and brings earnings volatility.

New energy and low-carbon businesses are investments to adapt the existing sales network and industrial facilities for the future. Hydrogen, charging and battery swapping, solar, geothermal, biofuels, and CCUS have significant policy relevance. From a credit perspective, it is positive that these activities help Sinopec maintain policy importance and reduce long-term business obsolescence risk. However, their effect in boosting short- to medium-term earnings and cash flow is limited; rather, they involve investment spending and execution risk. If payback is delayed, there may be limited impact on support-inclusive credit strength, but standalone FCF and debt reduction would be constrained.

Overall, Sinopec is an issuer that is “supported by upstream earnings, maintains its business base through downstream scale, and carries chemical losses and energy-transition investment.” It is strong on a support-inclusive basis, but by segment, earnings quality is not uniform. When assessing default risk on SINOPE senior bonds, support and scale are important. When considering relative value or continued holding, however, chemical losses, lower marketing profit, investment spending, and structural changes in domestic demand need to be weighted heavily.

4. Financial Profile and Analysis

In analysing Sinopec Group’s financial profile, the first step is to define the scope of public information. The 2024 Group annual report provides the income statement trend, investment allocation, and main operating metrics for 2022 to 2024. However, the latest detailed balance sheet, cash flow, debt maturity schedule, and unused committed lines for the Group parent or Group consolidation were not sufficiently obtained as of this report. Therefore, this section combines the Group’s profit trend with Sinopec Corp.’s public financials, while avoiding using Sinopec Corp.’s financials directly as an assessment of parent-company liquidity.

Sinopec Group’s 2024 income statement shows both its scale and thin margins. Operating income exceeds RMB3tn, but the operating profit margin is in the low 3% range and the net profit margin is in the mid-2% range. This indicates a business structure in which revenue scale is extremely large as an integrated energy and petrochemical company, while margins are easily compressed by crude and product prices, taxes and surcharges, raw materials, refining margins, and chemical spreads.

The 2024 profit decline does not immediately impair Sinopec’s credit quality. Net profit of RMB82.5bn is large in absolute terms, and the company has strong access to the domestic financial system and capital markets. However, the thin margins show that credit headroom relies not on high standalone profitability as an operating company, but on scale, government support, business diversification, and funding access. Sinopec Group should not be assessed by the same yardstick as private high-margin chemical companies or pure upstream companies.

Sinopec Corp.’s 2025 financials show both lower profit and resilient cash flow. IFRS revenue in 2025 was RMB2,783.6bn, down from RMB3,074.6bn in 2024, and operating profit fell by around 31.2% to RMB48.6bn. Profit attributable to shareholders was RMB32.5bn, sharply lower than RMB48.9bn in 2024. On the other hand, operating cash flow was RMB162.5bn, exceeding RMB149.4bn in 2024. Even though accounting profit declined, the company showed a degree of cash-flow resilience after working capital, inventory, taxes, and depreciation.

In 2025, after deducting capex and exploratory well expenditure from Sinopec Corp.’s operating cash flow, around RMB28.9bn remained on a simple calculation. However, this is not full free cash after dividends, share buybacks, leases, movements in time deposits, and other investing and financing items. Given substantial dividends and shareholder returns, funding transactions with the Group parent and affiliates, and the unverified location of cash at the parent, Sinopec Corp.’s cash flow alone should not be used to take comfort on liquidity for all SINOPE obligations.

In terms of leverage, Sinopec Corp.’s balance sheet is not excessively weak for a high-investment-grade operating company. Cash and cash equivalents at end-2025 were RMB81.1bn, and time deposits over three months were RMB69.8bn, for a total of RMB150.9bn. Debt, including short-term debt, long-term debt, and Group-related loans, was approximately RMB355.5bn, or approximately RMB531.0bn including lease liabilities. Total assets were RMB2,153.5bn and total capital was RMB986.9bn, indicating a substantial capital base. That said, current liabilities, including short-term debt, payables, and contract liabilities, were RMB698.6bn and exceeded current assets. This can be a normal working-capital structure for an oil and petrochemical company, but reliance on market access and bank relationships remains.

1Q 2026 appears to be a good start from a profit perspective. Sinopec Corp.’s CAS operating income declined 3.9% year on year to RMB706.7bn, but pre-tax profit rose 32.6% to RMB24.2bn and profit attributable to shareholders rose 28.2% to RMB17.0bn. IFRS profit attributable to shareholders was RMB17.7bn, up 26.9% year on year. However, operating cash flow moved from a positive RMB8.1bn in the prior-year quarter to negative RMB5.6bn. There is no need to be overly pessimistic because quarterly working-capital movements are large, but the lag between profit recognition and cash conversion is a monitoring item for an oil and petrochemical company.

Overall, Sinopec’s financial profile suggests that repayment and refinancing capacity in normal conditions is strong, supported by business scale, capital base, operating cash flow, and government-related market access. At the same time, margins are thin, profit at the core subsidiary fell sharply in 2025, and chemical losses widened. Since the detailed balance sheet, cash flow, and maturity schedule of the Group parent remain unverified, the assessment of Sinopec Group parent liquidity and leverage needs to be conservatively qualified. The credit floor is supported not by high standalone profitability, but by the combination of business scale, domestic importance, Sinopec Corp.’s cash generation, government support expectation, and capital market access.

5. Structural Considerations for Bondholders

The most important point for SINOPE bonds is not to confuse government support expectation, parent guarantee, issuing SPV, and Sinopec Corp.’s shares and assets. Sinopec Group is a central SOE, and S&P views the likelihood of government support as extremely high. However, neither the Chinese government nor SASAC provides a direct, unconditional, and irrevocable guarantee for all SINOPE bonds. Legal claims on individual bonds are governed by the issuer, guarantor, guarantee scope, governing law, registration and filing, covenants, tax, and cross-border remittance constraints.

The 2025 Deep Development 2025 Ltd. exchangeable bonds are a useful example for understanding structure. The bonds are HKD7.75bn, 0.75%, due 2032, issued by a wholly owned overseas subsidiary of Sinopec Group, and unconditionally and irrevocably guaranteed by China Petrochemical Corporation. The exchange property is Sinopec Corp. H shares, and proceeds were to be used to refinance existing offshore debt. Two points can be drawn from this transaction. First, Sinopec Group has access to offshore capital markets and can refinance using low-coupon, equity-linked instruments. Second, bond risk depends on the Sinopec Group guarantee, the exchange shares, specific terms, market price, and investor put and redemption conditions, and is not the same as that of a simple senior unsecured bond.

Structural support comes from Sinopec Group’s importance as a Chinese energy and petrochemical group, its large listed subsidiary Sinopec Corp., and its access to domestic and overseas financial markets. S&P’s assignment of the same A+ rating to the guaranteed exchangeable bonds as Sinopec Group’s long-term issuer credit rating indicates that it views the company’s guarantee as a credit substitute for that security. S&P also sees an extremely high likelihood that the government would intervene if needed. However, this does not constitute a blanket confirmation of recovery prospects or structural ranking for all individual SINOPE bonds.

For bondholders, the constraint is that the legal claim must be checked. Even if Sinopec Corp. has substantial cash flow, SINOPE creditors do not necessarily have direct access to Sinopec Corp.’s assets. If a parent guarantee exists, creditors can claim against the guarantor Sinopec Group, but access to Sinopec Corp. subsidiary assets, dividends, intra-group loans, related-party transactions, minority interests, regulatory approvals, and foreign-currency remittance are separate issues. For offshore bonds in particular, NDRC registration or post-issuance filing, SAFE-related matters, enforceability of cross-border guarantees, tax gross-up, negative pledge, cross default, and change of control need to be confirmed.

In investing in specific bonds, senior unsecured bonds, guaranteed bonds, exchangeable bonds, and perpetual securities should not be treated as equivalent. For exchangeable bonds, equity exchangeability and put/call terms drive pricing; if perpetual securities exist, subordination, coupon deferral, step-ups, and call incentives differ significantly. This report is an initial issuer credit review, not a termsheet-level investment memo. Therefore, when holding or newly purchasing SINOPE bonds, the Offering Circular for each target ISIN must be reviewed.

6. Capital Structure, Liquidity and Funding

It is natural to view Sinopec Group’s funding capacity as strong, but that strength is confirmed less by detailed public parent-company financials than by its financial access as a central SOE, Sinopec Corp.’s capital market access, domestic bank relationships, government support expectation, and track record in the offshore bond market. Because this report could not obtain the Group parent’s standalone cash, short-term debt, maturity schedule, or committed lines, the liquidity assessment is a preliminary assessment based on Sinopec Corp.’s public figures and the 2025 offshore refinancing example.

Sinopec Corp.’s end-2025 balance sheet shows substantial assets and capital, while also showing the scale of short-term working capital. Cash and cash equivalents of RMB81.1bn plus time deposits of RMB69.8bn total RMB150.9bn. Short-term financial debt appears to be at least around RMB120.3bn when combining short-term debt of RMB108.3bn and short-term Group-related loans of RMB11.9bn, which appears broadly coverable by cash and time deposits. However, total current liabilities are large at RMB698.6bn and include payables, contract liabilities, taxes, derivatives, and leases. For oil and petrochemical companies, inventories, receivables, and payables are large, and short-term liquidity depends on bank borrowing and operating collections.

Sinopec Corp.’s 2025 operating cash flow was RMB162.5bn and absorbed capex of RMB115.5bn and exploratory well expenditure of RMB18.1bn. This indicates that the company can fund a substantial portion of its normal investment burden internally. At the same time, after dividends, share buybacks, dividends to minority shareholders of subsidiaries, lease repayments, investments, and movements in time deposits, the cash balance declined from RMB91.3bn to RMB81.1bn. Sinopec Corp.’s funding capacity is sufficiently large, but its investment, shareholder returns, and working capital are also large relative to business scale.

The 2025 exchangeable bond issuance is evidence of offshore refinancing capacity. According to S&P materials, Sinopec Group intended to use proceeds from the bonds to refinance offshore bonds maturing in 2025. This indicates that the company can use flexible capital market instruments, including equity-linked securities. However, exchangeable bonds are affected by the H-share price, investor puts, exchange terms, and share supply and demand, so low-cost issuance cannot necessarily be replicated at all times.

In terms of capital structure, the important point for Sinopec is that capex and energy-transition investment will continue for a long period. Group total investment in 2024 was RMB223bn, allocated as RMB116bn to oil and gas and new energy, RMB46bn to refining and marketing, RMB50bn to chemicals and materials, and RMB8bn to research and development, IT, and other areas. This is necessary to maintain and transform the business base, but it can pressure free cash flow. S&P’s 2026 China commodities outlook also indicates that Sinopec Group is more likely to face pressure than peers because of its downstream-oriented business mix, while maintaining an A+/Stable base case.

The liquidity assessment is explicitly qualified. Sinopec Corp.’s public financials show that cash, operating cash flow, and capital base are large for an operating company. However, the Sinopec Group parent’s standalone foreign-currency liquidity, guaranteed debt, offshore bond maturities, reliance on subsidiary dividends, unused committed lines, and hedging position are unverified. Therefore, the liquidity assessment in this report is a qualitative assessment based on market access as a central SOE, Sinopec Corp.’s public financials, and the 2025 offshore refinancing example. It does not quantitatively confirm the parent company’s short-term debt coverage or foreign-currency liquidity.

7. Rating Agency View

The central rating material confirmed in this report is from S&P. In May 2025, S&P assigned an A+ long-term issuer-linked rating to Sinopec Group’s guaranteed Hong Kong dollar exchangeable bonds and referenced Sinopec Group’s long-term issuer credit rating of A+/Stable/A-1. S&P views the likelihood of extraordinary support from the Chinese government for Sinopec Group as extremely high and assesses the guarantee as functioning as a credit substitute. In its 2026 China commodities outlook, S&P also shows Sinopec Group as A+/Stable.

The important point in S&P’s view is that the rating is not determined by standalone financials alone. Sinopec Group’s business scale, integrated operations, and dominant position in domestic refining, marketing, and chemicals are strong, but the main reason for its A+ rating is its policy importance and government support expectation as a major Chinese state-owned oil company. S&P views Sinopec Group as more exposed to pressure in the current environment than more upstream-oriented peers such as CNOOC because of its higher downstream exposure. At the same time, this view does not negate the framework of viewing Sinopec as a high-investment-grade, support-inclusive credit. Rather, it highlights the need to separate business risk and government support.

The rating agency view is broadly consistent with this report’s analysis. Sinopec is a central SOE energy issuer with a high likelihood of Chinese government support, and its default risk cannot be explained solely by the standalone chemical and refining cycles. At the same time, a high rating does not mean that all individual bonds are guaranteed by the Chinese government or that all securities have the same recovery ranking. S&P’s A+ rating on the guaranteed exchangeable bonds is a specific judgment that the Sinopec Group guarantee functions as a credit substitute; it does not remove the need to check the terms of each bond.

The latest full issuer-specific reports from Fitch and Moody’s were not obtained for this report. Historically, rating materials have existed evaluating the government linkage, parent-subsidiary relationship, and role as a national oil company for Sinopec Corp. and Sinopec Group, but this report does not assert the latest triggers as of 2026-05-18. If rating differentials, outlooks, and downgrade triggers are used for investment decisions, the latest Fitch and Moody’s materials should be checked in addition to S&P.

Rating monitoring items include China’s sovereign rating and outlook, maintenance of S&P’s Sinopec Group A+/Stable rating, changes in government support assessment, Sinopec Corp.’s debt-to-EBITDA, cash flow after discretionary spending, chemical segment losses, offshore refinancing, and rating assignment conditions for specific guaranteed bonds. Because Sinopec is a support-inclusive credit, changes in the sovereign or central SOE support assessment may affect the rating more than changes in standalone financials.

8. Credit Positioning

Sinopec Group’s relative positioning should be viewed across multiple axes: the Chinese sovereign, policy banks, other Chinese national oil companies, central SOE chemical and resource companies, and private petrochemical companies. It has greater business risk than the sovereign or policy banks and has a stronger downstream and chemicals profile than CNPC/PetroChina and CNOOC. Compared with central SOE chemical companies such as ChemChina, Sinopec is stronger in terms of energy supply and the transparency of its listed core subsidiary, but the chemicals cycle and fuel demand transition still need to be monitored.

From a credit perspective alone, Sinopec Group senior guaranteed bonds are positioned as defensive credits with high support expectation even among Chinese central SOEs. The importance of energy supply and the petrochemical supply chain, the scale of the listed core subsidiary, and S&P A+/Stable support an upper-investment-grade profile. At the same time, even within the A+ category, Sinopec should not be treated in the same way as policy banks or more directly public-infrastructure-related issuers. Sinopec carries additional risks from the refining, marketing, and chemicals cycles, decarbonisation investment, medium-term changes in petroleum product demand, and individual-bond structures.

This report does not confirm live spreads, OAS, CDS, or same-maturity comparisons, so it does not make a rich/cheap conclusion on market relative value. For investment decisions, the key question is whether the spread differential versus same-maturity Chinese sovereign, policy bank, CNPC/CNOOC, State Grid, and other central SOE energy and chemical issuers sufficiently compensates investors for Sinopec’s business and structural risks. For exchangeable bonds, the analysis also needs to incorporate equity exchangeability, puts, share price, volatility, and share supply and demand.

9. Key Credit Strengths and Constraints

Sinopec Group’s largest credit strength is its difficult-to-substitute role in China’s energy and petrochemical supply chain. By combining one of China’s largest refining, marketing, and chemicals platforms with natural gas, upstream, engineering, new energy, and financial services, the company is not a single-product business but plays a role close to national industrial infrastructure. This role supports government support expectation, bank access, capital market access, and ratings.

The second strength is the transparency and cash generation of the business and financial profile, centred on Sinopec Corp. Profit declined in 2025, but operating cash flow was large at RMB162.5bn and absorbed a substantial portion of capex and exploration spending. The fact that the core business is listed and that annual reports, quarterly reports, and segment information can be reviewed is an important support factor among Chinese central SOE issuers.

The third strength is offshore capital market access and the support-inclusive rating. The 2025 HKD exchangeable bonds were issued to refinance existing offshore debt and received an A+ issuer-linked assessment from S&P. This indicates that Sinopec Group normally has access to diverse funding channels. Because the expectation of government support is strong, fluctuations in standalone business profit are unlikely to immediately eliminate refinancing capacity.

The first constraint is thin margins and business cyclicality. The Group’s operating margin is in the 3% range, and Sinopec Corp.’s 2025 operating margin was below 2%. Refining, marketing, and chemicals have large revenue scale, but are affected by prices, costs, taxes, inventories, and demand. In particular, the chemicals segment losses show that being a large petrochemical company and having a chemicals business that always supports credit quality are separate issues.

The second constraint is the energy transition. EVs, fuel-efficiency improvements, changes in logistics structures, urban policy, and decarbonisation constrain growth potential for petroleum product demand. Sinopec is investing in charging, battery swapping, hydrogen, solar, geothermal, and biofuels, but these are not yet large enough to fully replace earnings from the existing oil marketing and refining businesses. Transition investment helps maintain policy importance, but it also involves capex and payback risk.

The third constraint is information limitations at the parent-company and individual-bond levels. This report did not obtain the latest balance sheet, cash flow, maturity schedule, foreign-currency liquidity, or guaranteed debt at the Sinopec Group parent level. Sinopec Corp. figures are extensive, but the claims of SINOPE creditors, parent guarantees, access to subsidiary assets, and specific bond terms are separate issues. These unverified items limit the scope of the credit conclusion.

10. Downside Scenarios and Monitoring Triggers

The most realistic downside scenario is a combination of slower petroleum product demand, weaker chemical spreads, lower refining margins, and continued investment spending. In this case, even if revenue scale remains large, operating margins would become even thinner, and the cushion remaining after deducting capex, exploration spending, and dividends from Sinopec Corp.’s operating cash flow would narrow. If lower profit at the core subsidiary persists, it could also affect dividends and funding upstreamed to the parent, offshore refinancing, and S&P’s view of financial metrics.

The second downside is a prolonged loss in the chemicals business. If China’s petrochemical overcapacity continues, domestic demand and export prices remain weak, and feedstock costs such as naphtha and crude oil do not decline, chemicals segment losses could lead to capital consumption and restructuring burdens. Sinopec Group is advancing high-value-added materials and adjustments to low-margin facilities, but if overcapacity is an industry-wide problem, it cannot be rapidly resolved by one company’s efforts alone.

The third downside is a change in government support expectation or sovereign constraints. Sinopec is a support-inclusive credit, and its rating and refinancing capacity are linked to the Chinese sovereign, central SOE support policy, and confidence in the domestic financial system. If the support assessment changes, spreads could move even without a major deterioration in standalone financials.

The fourth downside is individual-bond structure. Senior bonds with parent guarantees, exchangeable bonds, perpetual securities, and SPV-issued bonds have different risk profiles. For exchangeable bonds, share price declines, failure to exchange, put exercise, and the refinancing environment affect prices. For SPV bonds, guarantee scope, governing law, NDRC/SAFE, foreign-currency remittance, tax, cross default, and negative pledge affect recoverability and early redemption risk. Strong credit quality does not justify skipping review of the terms.

Future monitoring should prioritise Sinopec Corp.’s 2026 interim results, 2026 full-year outlook, whether chemicals segment losses narrow, marketing and distribution profit, the gap between operating cash flow and capex, Group parent funding, S&P’s outlook for Chinese oil majors, the latest Fitch/Moody’s actions, and the maturities, terms, and market spreads of each SINOPE bond. In particular, it is necessary to confirm whether the profit improvement in 1Q 2026 continues for the full year and whether negative operating cash flow is merely seasonal.

11. Credit View and Monitoring Focus

Based on S&P’s A+/Stable/A-1 indication and government support assessment, the basic view is that Sinopec Group currently has upper-investment-grade, support-inclusive credit quality as a Chinese central SOE energy issuer. However, that level is not a direct guarantee from the Chinese government. It is supported by policy importance as a central SOE, business scale centred on Sinopec Corp., domestic financial access, and government support expectation. The credit direction is biased toward stability, but given the 2025 decline in Sinopec Corp.’s profit and widening chemical losses, it is still difficult to say that the standalone business trend has clearly shifted toward improvement. A rapid deterioration in the level or direction of credit quality is not highly likely as long as government support expectation and market access are maintained, but if a change in sovereign or central SOE support assessment, a deterioration in the offshore refinancing environment, and simultaneous weakness in chemical and marketing profit overlap, spreads or the rating outlook may react first.

This credit view is supported by Sinopec Group’s importance in China’s domestic energy and petrochemical supply chain. Sinopec Corp. is an important public proxy for assessing normal-course repayment and refinancing capacity, and it maintained large operating cash flow in 2025, with 1Q 2026 profit also improving year on year. However, this does not directly quantify parent-company foreign-currency liquidity or the payment source for specific guaranteed bonds.

Standalone business risk should not be ignored. Sinopec is not a regulated utility; it is an oil and petrochemical company exposed to market volatility. In 2025, Sinopec Corp. recorded declines in revenue, operating profit, and profit attributable to shareholders, while chemicals segment losses widened. Marketing and distribution profit also declined. EV adoption, fuel-efficiency improvements, petrochemical overcapacity, and decarbonisation investment are medium-term constraints. These do not immediately increase support-inclusive default risk, but they can affect relative valuation, spread requirements, and the pricing of long-dated bonds and exchangeable bonds within the same rating category.

For bond investors, the most important point is not to simplify Sinopec as “government-related, therefore sovereign-equivalent.” S&P views the likelihood of government support as extremely high, but individual SINOPE bonds are not direct obligations of the Chinese government. The scope of parent guarantees, issuing SPVs, equity linkage in exchangeable bonds, ranking of senior bonds and other securities, NDRC/SAFE, governing law, and covenants need to be checked. In particular, even when using Sinopec Corp.’s public financials, investors should always separate the point that SINOPE bondholders’ legal claim does not directly reach Sinopec Corp.’s assets.

In terms of holding stance, Sinopec Group senior guaranteed bonds have high defensive quality as Chinese central SOE energy credits. At the same time, compared with policy banks or more directly public-infrastructure-related SOEs, investors should require additional compensation for business cyclicality, chemical losses, energy transition, and individual-bond structural risks. Because live spreads are unavailable, this report does not assert buy, sell, cheap, or rich conclusions. For investment decisions, it is necessary to separately confirm whether the spread differential versus same-maturity Chinese sovereign, policy bank, CNPC, CNOOC, State Grid, and ChemChina/Sinochem group bonds sufficiently compensates for these additional risks.

Future monitoring should prioritise Sinopec Corp.’s 2026 interim and full-year results, the Group parent’s balance sheet and cash flow if the 2025 annual report is published, chemicals segment losses, marketing and distribution profit, operating cash flow versus capex, offshore maturities, the exchangeable bonds’ share price and put terms, the latest actions from S&P/Fitch/Moody’s, and China’s sovereign rating. If parent-company liquidity, maturity schedule, and individual-bond OCs can be obtained, the next update can move one step deeper from issuer credit to individual-bond credit.

12. Short Summary & Conclusion

Sinopec Group is a central SOE integrated energy and petrochemical group centred on China’s refining, petroleum product marketing, and petrochemicals, with operations also spanning upstream, natural gas, engineering, and new energy. Its credit quality is strongly supported by its importance to domestic energy security, the large business base centred on Sinopec Corp., and government support expectation reflected in S&P A+/Stable. At the same time, SINOPE bonds are not directly guaranteed by the Chinese government, and investors need to separately assess thin refining and chemical margins, chemical losses, medium-term changes in fuel demand, and unverified parent-company financials and individual-bond terms.
