Issuer Overview

• China Petroleum & Chemical Corporation / Sinopec Corp. is the listed flagship operating subsidiary of China Petrochemical Corporation / Sinopec Group.
• The company is listed in Hong Kong and Shanghai, with equity references HKEX 00386 and SSE 600028.
• The report scope is Sinopec Corp.'s own consolidated credit profile. It is separate from Sinopec Group parent credit, SINOPE parent-guaranteed offshore bonds, offshore SPVs, and the Chinese government / SASAC.
• At 31 December 2025, Sinopec Group held 69.87% of Sinopec Corp., including H shares held through Century Bright. The 2026 Q1 report showed direct parent A-share ownership of 68.79% plus Century Bright H-share ownership of 1.16%.
• Main businesses are exploration and production, refining, marketing and distribution, chemicals, and new energy / integrated energy services.

Core Credit View

• Sinopec Corp. is a support-influenced listed central-SOE operating company with large domestic fuel, refining, marketing and petrochemical importance.
• Its credit profile combines parent control, policy importance, domestic AAA rating and large operating cash flow with thin margins, chemical losses, fuel-demand transition pressure, capital expenditure needs and short-term refinancing dependence.
• In 2025, CAS operating income was RMB2.78tn, CAS net profit attributable to shareholders was RMB31.8bn, operating cash flow was RMB162.5bn and the liabilities-to-assets ratio was 54.08%.
• In 2026 Q1, profit rebounded year on year, but operating cash flow was negative because of working-capital pressure and hedging margin movements.

Business and Franchise View

• Sinopec Corp. is one of China's largest integrated energy and petrochemical companies, with a particularly strong downstream, refining, fuel-marketing and chemicals profile.
• Refining and marketing are central to its domestic franchise. In 2025, refinery throughput was about 250 million tonnes and refined oil product output was about 149 million tonnes.
• Exploration and Production is an important earnings stabiliser. In 2025, oil and gas production was 525.28 million boe, crude oil production was 282.40 million barrels and natural gas production was 1,456.63 bcf.
• Chemicals are a large business area but were loss-making in 2024, 2025 and 2026 Q1, reflecting overcapacity and weak product prices.
• The marketing network is being adapted through non-fuel retail, LNG refuelling, EV charging, battery swapping, hydrogen and integrated energy services, but these activities do not yet replace the earnings base of the existing refining, marketing and upstream businesses.

Capital Structure and Structural Points

• The analytical stack is: Sinopec Corp. listed operating-company debt, Sinopec Group as controlling shareholder and support background, then SASAC / China government ownership and policy background.
• Sinopec Corp. domestic bonds, Sinopec Corp. bank debt, Sinopec Group parent-guaranteed offshore bonds, exchangeable bonds linked to Sinopec Corp. shares and China government support expectations are separate structures.
• The 2025 annual report discloses domestic entity rating AAA and AAA ratings for certain interbank market debt financing instruments.
• Annual-report domestic bond information indicates relevant domestic debt is not automatically guaranteed; issue-specific terms must be checked separately.

Liquidity and Funding View

• 2025 operating cash flow was large at RMB162.5bn and broadly absorbed capital expenditure and exploration spending, but headroom after dividends, interest, lease payments, investments and debt repayment is not substantial.
• At end-2025, cash and cash equivalents plus time deposits were RMB150.9bn, while short-term debts were RMB108.3bn before considering other current funding needs.
• Current liabilities exceeded current assets at end-2025, so refinancing access to domestic banks and bond markets remains an important assumption.
• 2026 Q1 operating cash flow was an outflow of RMB5.6bn, so interim 2026 results are needed before treating the Q1 profit rebound as sustained credit improvement.

Credit Strengths

• Difficult-to-substitute role in China's refining, fuel marketing and petrochemical supply chain.
• De facto control by Sinopec Group and central-SOE support background.
• Large operating cash flow despite the 2025 profit decline.
• Upstream and natural-gas earnings complement downstream and chemical exposure.
• Domestic AAA rating and listed-company disclosure transparency.

Credit Weaknesses

• Thin margins and sharp 2025 profit decline.
• Chemicals segment losses widened in 2025 and remained negative in 2026 Q1.
• Domestic oil-product demand faces medium-term pressure from EV adoption, LNG trucks, fuel efficiency and logistics changes.
• Large capital expenditure and short-term debt create refinancing dependence.
• Parent support and government-related status do not equal a legal guarantee on every Sinopec Corp. obligation.

Rating Watchpoints

• Fitch Dodd-Frank material from November 2024 showed Sinopec Corp. Long-Term IDR A+/Negative and Short-Term IDR F1+, but a latest full Fitch report was not obtained.
• S&P public materials used in the workflow related mainly to Sinopec Group support context, not a complete Sinopec Corp. issuer-specific rating rationale.
• Latest full Fitch, Moody's and S&P issuer-specific materials for Sinopec Corp. remain to be confirmed before a rating-focused update.

Ongoing Follow-Up Items

• Check Sinopec Corp. 2026 interim and full-year results, with emphasis on segment EBIT, chemical losses, Marketing and Distribution profit, operating cash flow, capex, dividends, short-term debt and debentures payable.
• Track whether the 2026 Q1 profit rebound converts into sustained operating cash flow improvement or remains a quarter affected by inventory gains, margins and working capital.
• Monitor domestic refined oil demand, gasoline and diesel demand, jet fuel, EV/LNG substitution, refining margins and inventory gains or losses.
• Monitor chemical overcapacity indicators, including ethylene-equivalent demand, PX, synthetic resin/fibre/rubber demand, product prices, impairments and the shift toward high-value materials.
• Track funding structure, including domestic MTNs / sci-tech innovation bonds, one-year maturities, bank facilities, foreign-currency debt, hedging, group loans and lease liabilities.

Unresolved Issues and Items to Check Next Time

• Latest full Fitch, Moody's and S&P issuer-specific rating reports and rating triggers for Sinopec Corp.
• Detailed debt maturity ladder, unused committed bank lines, restricted cash, foreign-currency debt, foreign-currency cash and hedge position.
• Individual domestic and offshore bond prospectuses or offering circulars before any issue-specific recommendation.
• Live prices, spreads, OAS, CDS and peer curves versus China sovereign, policy banks, CNPC/PetroChina, CNOOC, Sinopec Group and ChemChina/Sinochem.
• Whether chemicals segment losses narrow and whether Marketing and Distribution profit stabilises after the 2025 decline.

Analytical Cautions

• Do not treat Sinopec Corp. as the same legal entity as Sinopec Group.
• Do not call Sinopec Corp. debt China government-guaranteed unless the specific bond document says so.
• Do not use Sinopec Group-guaranteed exchangeable bonds as a proxy for all Sinopec Corp. debt.
• Do not read chemical scale as automatically credit-positive; chemicals were loss-making in 2024, 2025 and 2026 Q1.
• Do not treat one quarter of refining or inventory gains as sustained recovery.
• Do not make a relative-value call without live spreads, OAS, CDS and same-maturity peer curves.

Report Wording Cautions

• Use "support-influenced listed central-SOE operating company" or similar wording, not "sovereign-guaranteed issuer."
• Keep "parent support expectation" separate from "legal guarantee."
• When using Sinopec Group or SINOPE context, state that it is parent or bond-structure context rather than Sinopec Corp.'s own legal obligation unless the document proves otherwise.
• When discussing 2026 Q1, say that profit improved but operating cash flow was negative; do not frame it as confirmed full-year recovery.

Follow-Up on Management Strategy, Investment Plans, and Financial Policy

• Recheck capital expenditure allocation across E&P, refining, marketing, chemicals and new energy.
• Monitor whether high-value chemical materials, EV charging, hydrogen, LNG refuelling, battery swapping and non-fuel services become material earnings contributors or remain policy / adaptation investments.
• Watch dividend policy and shareholder returns because operating cash flow headroom after capex and exploration spending is limited.
• Reassess whether energy-transition investment is preserving long-term franchise value without worsening short-term FCF and leverage.

Items to Check for Ratings and Bond Investors

• Confirm issuer, guarantor, guarantee scope, ranking, negative pledge, cross default, change of control, NDRC/SAFE, governing law, tax gross-up, put/call and exchangeable features for each bond.
• Check whether any domestic bond table explicitly states no guarantee or other structural limitations.
• Separate domestic bond analysis, listed-company bank debt analysis, parent-guaranteed offshore analysis and exchangeable-bond analysis.
• Compare Sinopec Corp. with PetroChina/CNPC and CNOOC while explicitly adjusting for Sinopec Corp.'s heavier downstream and chemicals exposure.
