Issuer Overview

• CNOOC Limited is the listed upstream platform of China National Offshore Oil Corporation. It is listed in Hong Kong and Shanghai under HKEX 00883 / RMB counter 80883 and SSE 600938.
• It is China's largest offshore crude oil and natural gas producer and one of the larger independent upstream E&P companies globally.
• The core China operating areas are Bohai, Western South China Sea, Eastern South China Sea, East China Sea and onshore unconventional gas. Overseas assets are spread across Asia, Africa, North America, South America, Oceania and Europe.
• CNOOC Group is the substantial ultimate holding company and held approximately 62.13% of CNOOC Limited's total issued shares in the 2025 Annual Report.

Core Credit View

• The issuer is best read as a high-quality upstream E&P credit with central-SOE linkage. Standalone strength comes from scale, low cost, reserve life, cash generation and a net-cash-type balance sheet.
• Support-linked strength comes from CNOOC Group's policy role in Chinese offshore oil and gas and the strategic importance of domestic energy security.
• CNOOC Limited debt should not be described as Chinese government-guaranteed unless the specific instrument provides such a guarantee. Government support expectations, parent linkage and CNOOC Limited guarantees are separate concepts.

Business and Franchise View

• The company is upstream-heavy rather than a fully integrated oil major. Revenue and cash flow are concentrated in exploration, development, production and sale of crude oil and natural gas.
• China remains the core production and reserve base, which strengthens policy relevance and parent linkage. Overseas assets add scale and growth but bring country, sanctions, partner, tax, FPSO, deepwater and environmental risks.
• Low cost is a key recurring strength. FY2025 all-in cost was US$27.90/BOE, and cost discipline is central to the issuer's ability to absorb lower oil prices.
• FY2025 production and reserves both increased, with simple reserve life around 10 years. FY2026 started with record 1Q production, but one quarter should not be treated as a full-cycle credit conclusion.

Capital Structure and Structural Points

• The 2025 Annual Report identifies notes issued by CNOOC Finance entities and CNOOC Petroleum North America ULC as fully and unconditionally guaranteed by CNOOC Limited in note 27, but the terms of each offering circular have not been reviewed.
• The listed issuer, parent group, finance subsidiaries, project-related guarantees and Chinese government support must be separated in bond analysis.
• CNOOC Limited had a conservative end-2025 capital structure, with interest-bearing debt far below cash, time deposits within one year and current financial assets.

Liquidity and Funding View

• Liquidity is a major credit strength. End-2025 cash, time deposits within one year and current other financial assets materially exceeded total interest-bearing debt.
• Short-term refinancing risk is low at issuer level under normal market conditions, but specific offshore notes still require review of legal obligor, guarantee, governing law, NDRC / SAFE and sanctions clauses.
• The issuer's financial flexibility depends on maintaining operating cash flow through the commodity cycle while funding high annual oil and gas capex and dividends.

Credit Strengths

• Dominant position in offshore China and strong policy importance.
• Large reserve base, continuing production growth and reserve life of about 10 years on the initial-coverage calculation.
• Low all-in cost and strong operating cash flow.
• Very conservative balance sheet with liquid financial assets materially above interest-bearing debt.
• Public-market transparency from HKEX / SSE listing.
• Publicly confirmed high-grade rating context: Fitch A / Stable and S&P public issuer-ranking table A+ / Stable.

Credit Weaknesses

• Upstream concentration creates direct oil-price and reserve-conversion risk, unlike integrated majors with downstream or trading buffers.
• Offshore and deepwater projects are capital-intensive and operationally complex.
• Overseas growth brings country, sanctions, host-government, security, tax and partner risks.
• Dividend policy reduces retained cash in weaker price cycles.
• Individual bond documentation has not yet been reviewed issue by issue.

Rating Watchpoints

• China sovereign rating actions, CNOOC Group support assessment, CNOOC Limited standalone profile and rating-agency views of GRE support can affect spreads before operating results deteriorate.
• Moody's information remains limited to a secondary Cbonds headline in the initial coverage; original Moody's materials should be retrieved before relying on that rating.

Recurring Analytical Cautions

• Do not equate parent or government support expectations with a legal sovereign guarantee.
• Do not read production growth alone as credit improvement if it requires capex that weakens free cash flow or reserve economics.
• Do not treat overseas diversification as automatically risk-reducing; each asset region has distinct political, sanctions, partner and operating risks.

Ongoing Follow-Up Items

• Monitor whether production growth remains internally funded. The company targets 780-800mmboe production and RMB112-122bn oil and gas capex in 2026.
• Watch the dividend payout floor. Management indicates a payout ratio floor of no less than 45% for 2025-2027, subject to shareholder approval and market/operating conditions; this is manageable while operating cash flow remains high but reduces retained-cash upside in weaker oil-price years.
• Track quarterly operating results: net production, China versus overseas split, oil versus gas split, oil and gas sales, realized oil and gas prices, all-in cost and capex.
• Track annual disclosure for proved reserves, reserve replacement, reserve life, net cash position, interest-bearing debt, cash / time deposits / current financial assets, capex, dividends, dismantlement provisions and related-party balances.

Unresolved Issues and Items to Check Next Time

• Individual offering circulars and supplemental offering circulars for CNOOC Finance and CNOOC Petroleum North America notes have not been reviewed issue by issue. Before any bond-specific recommendation, confirm issuer, guarantor, guarantee scope, ranking, negative pledge, cross default, events of default, change of control, tax gross-up, governing law, NDRC / SAFE and sanctions / exchange-control language.
• Full Fitch, S&P and Moody's issuer-specific reports were not all accessed directly in the initial coverage. Fitch was available through a secondary republication, S&P through a public issuer-ranking table, and Moody's only through a Cbonds headline.
• CNOOC Group's latest full group financials and detailed government-support materials were not obtained. Parent and government linkage assessment should be refreshed when those sources are available.
• Detailed commodity-price sensitivity, hedge position, project-level economics and reserve replacement by project were not fully modelled.
• Live bond prices, OAS, CDS and same-maturity peer curves were not available in the workspace.

Analytical Cautions

• Keep CNOOC Limited, CNOOC Group, CNOOC Finance issuing vehicles, CNOOC Petroleum North America ULC and Chinese government support separate. A CNOOC Limited guarantee can be strong without making the bonds PRC sovereign obligations.
• The core single-name risk is not downstream margin, but oil and gas price volatility, reserve conversion, offshore execution, overseas political risk, HSSE incidents and capital discipline.
• Treat rating support carefully. Fitch links CNOOC Limited to CNOOC Group and the Chinese sovereign framework while also assigning a strong standalone credit profile; a sovereign or parent-support reassessment can move spreads faster than operating results.
• Overseas assets require separate risk review. Guyana Stabroek, Brazil Mero / Buzios, Canada Long Lake, Uganda Kingfisher, Indonesia Tangguh / NWS and any Russia-related exposure have different country, sanctions, tax, partner and operating-risk profiles.

Report Wording Cautions

• Do not describe CNOOC Limited debt as directly guaranteed by the Chinese government unless the specific instrument says so.
• Avoid treating "central SOE-linked" as equivalent to sovereign credit. Use language such as support expectations, strategic importance, parent linkage and explicit CNOOC Limited guarantees where confirmed.
• Avoid implying that a single strong quarter eliminates upstream cyclicality. The report should continue to distinguish near-term production momentum from commodity-price and capex risk.

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

• Check whether the 2026 production target and capex plan are executed without materially weakening post-dividend free cash flow.
• Monitor whether low-carbon, gas and offshore-wind initiatives remain secondary to the oil and gas repayment base or begin to affect capital allocation materially.
• Track management comments on dividend policy, reserve replacement and overseas growth projects.

Items to Check for Ratings and Bond Investors

• Fitch / S&P / Moody's actions on CNOOC Limited, CNOOC Group and the China sovereign.
• Rating-agency support assumptions, standalone credit profile, downgrade triggers and liquidity assessment.
• Issue-by-issue guarantees, negative pledge, cross-default, NDRC / SAFE and sanctions language for CNOOC Finance and CNOOC Petroleum North America notes.
• Relative spread versus the China sovereign, policy banks, CNPC / PetroChina, Sinopec, State Grid, PETRONAS, PTTEP and global E&P peers when reliable market data are available.
