Part 1 · What the company is worth
Overview
IRPC refines crude oil into fuels and turns some of that output into petrochemicals, at an integrated site in Thailand that is the country's second-largest refinery, with capacity of about 215,000 barrels a day. It also sells lubricants, asphalt and plastics such as polyethylene and polypropylene. The company is majority-linked to Thailand's national oil company PTT, which owns roughly 45% of it and supplies its crude oil.
How it makes money
Revenue comes from selling refined fuels, petrochemicals and related products at market prices, so profit depends on the spread between the cost of crude oil and the price of what comes out the other end — a margin that swings with global oil and petrochemical markets rather than being set by the company. PTT supplies essentially all of its crude, but at market price rather than at a discount, so ownership does not translate into a lower input cost.
Competitive moat
No identified moat · NoneIRPC buys its main input, crude oil, at market price even from its own parent company, and sells fuels and basic petrochemicals that are largely undifferentiated commodities priced on global markets. Being Thailand's second-largest refiner gives it local scale, but not a cost or pricing advantage over other refiners exposed to the same crude and product prices.
What drives demand
CyclicalAs a refiner and petrochemical producer, results move with global crude oil prices and refining margins, which swing with the broader economy, energy demand and regional refining capacity — not with any steady, non-discretionary consumption pattern.
The case for
Buyers argue that being tied to PTT, Thailand's national oil company and a roughly 45% owner, gives IRPC funding support and credit-rating uplift in stressed periods, and that its position as the country's second-largest, fully integrated refining-and-petrochemical complex is not easily replicated.
The case against
Sellers fear that buying crude at market price even from its own parent leaves IRPC with no cost advantage, that refining and petrochemical margins are set by volatile global markets outside its control, and that a commodity business with no pricing power offers little protection when those margins compress.
