01Two businesses

India's biggest refiner and fuel retailer

Indian Oil Corporation (IOC) is a state-owned oil company and India's largest refiner, with refineries including Panipat, Mathura, Gujarat and Paradip. It runs the country's largest network of petrol pumps and of product pipelines.

Three businesses under one share price

Reliance Industries started out in textiles and petrochemicals and is now India's most valuable listed company. Its oldest engine, oil-to-chemicals (O2C), runs the Jamnagar refining complex and turns crude oil into fuels, polymers and polyester. Profits there rise and fall with global refining margins, which is why the segment is valued as a capital-heavy commodity business.

02The records side by side

On revenue the two have grown at much the same pace: Indian Oil compounded at about 7% a year (FY2018–FY2026) and Reliance Industries at about 9% (FY2019–FY2026). By revenue the two are of broadly similar size. Indian Oil kept 4.8% of revenue as net profit in FY2026; Reliance Industries kept 8.9% of revenue as net profit in FY2026. Indian Oil reported a net loss in FY2020; Reliance Industries was profitable in every year shown.

Indian Oil. The FY2020 loss and the big swings since come mostly from refining margins and inventory gains or losses as crude prices moved, not from changes in volume.
Reliance Industries. Revenue dipped in FY2021 when oil prices collapsed during the pandemic, then rebounded as crude recovered and Jio and Retail kept scaling.

04What decides each one's value

  • Gross refining marginsThe difference between product prices and crude costs drives refining profit.
  • Marketing marginsHow far retail prices are allowed to track costs decides fuel-retail profit.
  • Jio's revenue per userThe network is already built, so each tariff increase drops almost straight to profit. How far revenue per user can rise without losing subscribers is the biggest single swing factor in the group's value.
  • Retail's store economicsRetail is worth what each store earns once it matures, not how many stores open. Slower same-store growth would shrink this part of the valuation faster than any other.

05What could go wrong

  • Government pricingRetail fuel prices can be held down when crude rises.
  • Crude volatilitySharp moves in oil prices create big swings in reported profit.
  • The holding-company discountMarkets often value conglomerates below the sum of their parts, and that discount can last for years.
  • New energy is still a betThe solar, battery and hydrogen projects are early, capital-hungry and not yet proven at scale.
