Company overview

Indian Oil Corporation Limited (IOC) is India's largest oil refining and marketing company, a Maharatna PSU under the Ministry of Petroleum and Natural Gas. The company operates 11 refineries with a combined capacity of approximately 81 million metric tonnes per annum (MMTPA), making it the largest Indian refiner ahead of Reliance Industries (which has higher single-refinery capacity at Jamnagar but smaller aggregate). IOC operates the largest retail petroleum distribution network in India with over 36,000 fuel stations, 12,000 LPG distributors, and ownership of cross-country pipeline infrastructure spanning over 15,000 kilometres. The company is also a meaningful petrochemicals producer and has emerging investments in green hydrogen, biofuels, and EV charging infrastructure through its IndianOil-Total joint venture and the IndianOil-Adani Gas city gas distribution network.

Business model

IOC operates five reporting segments: Petroleum Products (refining and marketing), Petrochemicals, Pipelines, Gas (LPG, Natural Gas, CNG), and Renewables and Alternate Energy. The Petroleum Products segment is the largest by revenue, with the marketing arm benefiting from administered pricing for some products and market pricing for others. The Petrochemicals segment serves Indian industrial customers and exports. Pipelines provide stable utility-style cash flow. The Gas segment includes both LPG distribution and the growing CGD (city gas distribution) network. The Renewables segment is in early ramp with hydrogen and biofuels investments.

Operating segments

Financial performance and recent trajectory

IOC reported FY25 consolidated revenue of approximately ₹8.77 lakh crore with net profit of ₹39,500 crore. The business is cyclical, tracking Singapore complex gross refining margins (GRM) and the administered pricing of diesel and LPG. Capital expenditure run-rate is approximately ₹30,000 to ₹35,000 crore per year supporting refinery expansion, petrochemicals integration, and renewable energy investments.

Stock performance and shareholder context

IOC (NSE: IOC, BSE: 530965) is a Nifty 50 constituent. Government of India holds majority shareholding (above 51 percent). High dividend payout typical for Maharatna PSU.

Competitive position

IOC is the largest by aggregate refining capacity and the largest retail footprint, ahead of BPCL, HPCL, Reliance Industries (in marketing), and Nayara Energy. The marketing scale and the pipeline infrastructure are the structural moats.

Key risks

Crude price volatility; administered pricing risk on LPG and diesel; transition to electric mobility; refinery capex execution; petrochemicals margin cyclicality.

Outlook

Through FY30 the principal trajectories are the refinery capex completing across Panipat and Paradip, the green hydrogen pilot scaling, the CGD network reaching peak penetration, and the EV charging infrastructure rolling out. For businesses entering oil and gas adjacent sectors, IOC is the principal counterparty for procurement, JV, and distribution.
